Controller 107 wirelessly transmits data such as game control data to the game console 100. The game control data may be generated using an operation section of controller 107 having, for example, a plurality of operation buttons, a direction key and the like. Controller 107 may also wirelessly receive data transmitted from game console 100. Any one of various wireless protocols such as Bluetooth (registered trademark) may be used for the wireless transmissions between controller 107 and game console 100.
As discussed below, controller 107 also includes an imaging information calculation section for capturing and processing images from light-emitting devices 108a and 108b. Although markers 108a and 108b are shown in
With reference to the block diagram of
In one example implementation, optical disk drive 208 receives both optical disks of a first type (e.g., of a first size and/or of a first data structure, etc.) containing applications developed to take advantage of the capabilities of CPU 204 and graphics processor 216 and optical disks of a second type (e.g., of a second size and/or a second data structure) containing applications originally developed for execution by a CPU and/or graphics processor having capabilities different than those of CPU 204 and/or graphics processor 216. For example, the optical disks of the second type may be applications originally developed for the Nintendo GameCube platform.
CPU 204 is connected to system LSI 202 that includes graphics processing unit (GPU) 216 with an associated graphics memory 220, audio digital signal processor (DSP) 218, internal main memory 222 and input/output (10) processor 224.
10 processor 224 of system LSI 202 is connected to one or more USB ports 226, one or more standard memory card slots (connectors) 228, WiFi module 230, flash memory 232 and wireless controller module 240.
USB ports 226 are used to connect a wide variety of external devices to game console 100. These devices include by way of example without limitation game controllers, keyboards, storage devices such as external hard-disk drives, printers, digital cameras, and the like. USB ports 226 may also be used for wired network (e.g., LAN) connections. In one example implementation, two USB ports 226 are provided.
Standard memory card slots (connectors) 228 are adapted to receive industry-standard-type memory cards (e.g., SD memory cards). In one example implementation, one memory card slot 228 is provided. These memory cards are generally used as data carriers but of course this use is provided by way of illustration, not limitation. For example, a player may store game data for a particular game on a memory card and bring the memory card to a friend's house to play the game on the friend's game console. The memory cards may also be used to transfer data between the game console and personal computers, digital cameras, and the like.
WiFi module 230 enables game console 100 to be connected to a wireless access point. The access point may provide internet connectivity for on-line gaming with players at other locations (with or without voice chat capabilities), as well as web browsing, e-mail, file downloads (including game downloads) and many other types of on-line activities. In some implementations, WiFi module may also be used for communication with other game devices such as suitably-equipped hand-held game devices. Module 230 is referred to herein as “WiFi”, which is generally a designation used in connection with the family of IEEE 802.11 specifications. However, game console 100 may of course alternatively or additionally use wireless modules that conform to other wireless standards.
Flash memory 232 stores, by way of example without limitation, game save data, system files, internal applications for the console and downloaded data (such as games).
Wireless controller module 240 receives signals wirelessly transmitted from one or more controllers 107 and provides these received signals to 10 processor 224. The signals transmitted by controller 107 to wireless controller module 240 may include signals generated by controller 107 itself as well as by other devices that may be connected to controller 107. By way of example, some games may utilize separate right- and left-hand inputs. For such games, another controller (not shown) may be connected to controller 107 and controller 107 can transmit to wireless controller module 240 signals generated by itself and by the other controller.
Wireless controller module 240 may also wirelessly transmit signals to controller 107. By way of example without limitation, controller 107 (and/or another game controller connected thereto) may be provided with vibration circuitry and vibration circuitry control signals may be sent via wireless controller module 240 to control the vibration circuitry (e.g., by turning the vibration circuitry on and off). By way of further example without limitation, controller 107 may be provided with (or be connected to) a speaker (not shown) and audio signals for output from this speaker may be wirelessly communicated to controller 107 via wireless controller module 240. By way of still further example without limitation, controller 107 may be provided with (or be connected to) a display device (not shown) and display signals for output from this display device may be wirelessly communicated to controller 107 via wireless controller module 240.
Proprietary memory card slots 246 are adapted to receive proprietary memory cards. In one example implementation, two such slots are provided. These proprietary memory cards have some non-standard feature(s) such as a non-standard connector and/or a non-standard memory architecture. For example, one or more of the memory card slots 246 may be adapted to receive memory cards used with the Nintendo GameCube platform. In this case, memory cards inserted in such slots can transfer data from games developed for the GameCube platform. In an example implementation, memory card slots 246 may be used for read-only access to the memory cards inserted therein and limitations may be placed on whether data on these memory cards can be copied or transferred to other storage media such as standard memory cards inserted into slots 228.
One or more controller connectors 244 are adapted for wired connection to respective game controllers. In one example implementation, four such connectors are provided for wired connection to game controllers for the Nintendo GameCube platform. Alternatively, connectors 244 may be connected to respective wireless receivers that receive signals from wireless game controllers. These connectors enable players, among other things, to use controllers for the Nintendo GameCube platform when an optical disk for a game developed for this platform is inserted into optical disk drive 208.
A connector 248 is provided for connecting game console 100 to DC power derived, for example, from an ordinary wall outlet. Of course, the power may be derived from one or more batteries.
GPU 216 performs image processing based on instructions from CPU 204. GPU 216 includes, for example, circuitry for performing calculations necessary for displaying three-dimensional (3D) graphics. GPU 216 performs image processing using graphics memory 220 dedicated for image processing and a part of internal main memory 222. GPU 216 generates image data for output to television 102 by audio/video connector 214 via audio/video IC (interface) 212.
Audio DSP 218 performs audio processing based on instructions from CPU 204. The audio generated by audio DSP 218 is output to television 102 by audio/video connector 214 via audio/video IC 212.
External main memory 206 and internal main memory 222 are storage areas directly accessible by CPU 204. For example, these memories can store an application program such as a game program read from optical disc 104 by the CPU 204, various types of data or the like.
ROM/RTC 238 includes a real-time clock and preferably runs off of an internal battery (not shown) so as to be usable even if no external power is supplied. ROM/RTC 238 also may include a boot ROM and SRAM usable by the console.
Power button 242 is used to power game console 100 on and off. In one example implementation, power button 242 must be depressed for a specified time (e.g., one or two seconds) to turn the console off so as to reduce the possibility of inadvertently turn-off. Reset button 244 is used to reset (re-boot) game console 100.
With reference to
Cross-switch 302a is described by way of example and other types of operation sections may be used. By way of example without limitation, a composite switch including a push switch with a ring-shaped four-direction operation section and a center switch may be used. By way of further example without limitation, an inclinable stick projecting from the top surface of housing 301 that outputs signals in accordance with the inclining direction of the stick may be used. By way of still further example without limitation, a horizontally slidable disc-shaped member that outputs signals in accordance with the sliding direction of the disc-shaped member may be used. By way of still further example without limitation, a touch pad may be used. By way of still further example without limitation, separate switches corresponding to at least four directions (e.g., front, rear, right and left) that output respective signals when pressed by a player can be used.
Buttons (or keys) 302b through 302g are provided rearward of cross-switch 302a on the top surface of housing 301. Buttons 302b through 302g are operation devices that output respective signals when a player presses them. For example, buttons 302b through 302d are respectively a “1” button, a “2” button and an “A” button and buttons 302e through 302g are respectively a “+” key, a menu switch, and a “−” key, for example. Generally, buttons 302b through 302g are assigned various functions in accordance with the application being executed by game console 100. In an exemplary arrangement shown in
Button 302h is provided forward of cross-switch 302a on the top surface of the housing 301. Button 302h is a power switch for remote on-off switching of the power to game console 100. Button 302h may also be recessed from a top surface of housing 301 to reduce the possibility of inadvertent pressing by a player.
A plurality (e.g., four) of LEDs 304 is provided rearward of button 302c on the top surface of housing 301. Controller 107 is assigned a controller type (number) so as to be distinguishable from other controllers used with game console 100 and LEDs 304 may be used to provide a player a visual indication of this assigned controller number. For example, when controller 107 transmits signals to wireless controller module 240, one of the plurality of LEDs corresponding to the controller type is lit up.
With reference to
As shown in
Connector 303 is provided on a rear surface of controller housing 301. Connector 303 is used to connect devices to controller 107. For example, a second controller of similar or different configuration may be connected to controller 107 via connector 303 in order to allow a player to play games using game control inputs from both hands. Other devices including game controllers for other game consoles, input devices such as keyboards, keypads and touchpads and output devices such as speakers and displays may be connected to controller 107 using connector 303.
For ease of explanation in what follows, a coordinate system for controller 107 will be defined. As shown in
As shown in the block diagram of
As one skilled in the art understands, linear accelerometers, as used in acceleration sensor 507, are only capable of detecting acceleration along a straight line corresponding to each axis of the acceleration sensor. In other words, the direct output of acceleration sensor 507 is limited to signals indicative of linear acceleration (static or dynamic) along each of the two or three axes thereof. As a result, acceleration sensor 507 cannot directly detect movement along a non-linear (e.g. arcuate) path, rotation, rotational movement, angular displacement, tilt, position, attitude or any other physical characteristic.
However, through additional processing of the linear acceleration signals output from acceleration sensor 507, additional information relating to controller 107 can be inferred or calculated (i.e., determined), as one skilled in the art will readily understand from the description herein. For example, by detecting static, linear acceleration (i.e., gravity), the linear acceleration output of acceleration sensor 507 can be used to determine tilt of the object relative to the gravity vector by correlating tilt angles with detected linear acceleration. In this way, acceleration sensor 507 can be used in combination with micro-computer 502 of controller 107 (or another processor) to determine tilt, attitude or position of controller 107. Similarly, various movements and/or positions of controller 107 can be calculated through processing of the linear acceleration signals generated by acceleration sensor 507 when controller 107 containing acceleration sensor 307 is subjected to dynamic accelerations by, for example, the hand of a user, as will be explained in detail below.
In another embodiment, acceleration sensor 507 may include an embedded signal processor or other type of dedicated processor for performing any desired processing of the acceleration signals output from the accelerometers therein prior to outputting signals to micro-computer 502. For example, the embedded or dedicated processor could convert the detected acceleration signal to a corresponding tilt angle (or other desired parameter) when the acceleration sensor is intended to detect static acceleration (i.e., gravity).
Returning to
Vibration circuit 512 may also be included in controller 107. Vibration circuit 512 may be, for example, a vibration motor or a solenoid. Controller 107 is vibrated by actuation of the vibration circuit 512 (e.g., in response to signals from game console 100), and the vibration is conveyed to the hand of the player grasping controller 107. Thus, a so-called vibration-responsive game may be realized.
As described above, acceleration sensor 507 detects and outputs the acceleration in the form of components of three axial directions of controller 107, i.e., the components of the up-down direction (Z-axis direction), the left-right direction (X-axis direction), and the front-rear direction (the Y-axis direction) of controller 107. Data representing the acceleration as the components of the three axial directions detected by acceleration sensor 507 is output to communication section 506. Based on the acceleration data which is output from acceleration sensor 507, a motion of controller 107 can be determined.
Communication section 506 includes micro-computer 502, memory 503, wireless module 504 and antenna 505. Micro-computer 502 controls wireless module 504 for transmitting and receiving data while using memory 503 as a storage area during processing. Micro-computer 502 is supplied with data including operation signals (e.g., cross-switch, button or key data) from operation section 302, acceleration signals in the three axial directions (X-axis, Y-axis and Z-axis direction acceleration data) from acceleration sensor 507, and processing result data from imaging information calculation section 505. Micro-computer 502 temporarily stores the data supplied thereto in memory 503 as transmission data for transmission to game console 100. The wireless transmission from communication section 506 to game console 100 is performed at predetermined time intervals. Because game processing is generally performed at a cycle of 1/60 sec. (16.7 ms), the wireless transmission is preferably performed at a cycle of a shorter time period. For example, a communication section structured using Bluetooth (registered trademark) technology can have a cycle of 5 ms. At the transmission time, micro-computer 502 outputs the transmission data stored in memory 503 as a series of operation information to wireless module 504. Wireless module 504 uses, for example, Bluetooth (registered trademark) technology to send the operation information from antenna 505 as a carrier wave signal having a specified frequency. Thus, operation signal data from operation section 302, the X-axis, Y-axis and Z-axis direction acceleration data from acceleration sensor 507, and the processing result data from imaging information calculation section 505 are transmitted from controller 107. Game console 100 receives the carrier wave signal and demodulates or decodes the carrier wave signal to obtain the operation information (e.g., the operation signal data, the X-axis, Y-axis and Z-axis direction acceleration data, and the processing result data). Based on this received data and the application currently being executed, CPU 204 of game console 100 performs application processing. If communication section 506 is structured using Bluetooth (registered trademark) technology, controller 107 can also receive data wirelessly transmitted thereto from devices including game console 100.
In this particular example, the game player provides inputs to the video game system to control the position of targeting marker 502. The game player may control the position of targeting marker 502 by any convenient means such as by tilting handheld controller as described above, moving a joystick, moving a stylus in contact with a touch screen, or any other convenient method. As the game player moves targeting marker 502, the video game system automatically animates character 504 so that the character turns toward the targeting marker and the character's weapon 506 is always pointing toward the targeting marker. In this way, the game player selects where animated game character 504 is aiming his weapon 506.
For example, if the game player positions targeting marker 502 directly above a displayed enemy (not shown) within a 3D scene, then animated character 504 is controlled to automatically aim his weapon 506 at the targeting marker and thus at the enemy. In this exemplary illustrative non-limiting implementation, targeting marker 502 is displayed as if it were positioned on a virtual reticle or other 2D overlay in front of the entire scene. However, in other exemplary illustrative non-limiting implementations, the targeting marker 502 could be a laser pointer, a tracer bullet, or any other indicator within the 3D scene itself.
Image 500 is “captured” from the perspective of a virtual camera VC also located within the same 3D world as character 504. See
In this particular exemplary illustrative non-limiting implementation, the targeting marker 502 is shown positioned “on” the game character 504 itself so that that game player does not lose sight of the targeting marker 502. As discussed above, however, other arrangements are possible.
In one exemplary illustrative non-limiting implementation, a virtual invisible plane may be defined between the virtual camera VC and the centroid of the game character 504. As the targeting marker 502 passes through that virtual plane, the virtual camera VC changes position by moving and/or pivoting to the left so that it is now viewing the 3D scene over the game character's left shoulder 510. In one exemplary illustrative non-limiting implementation, the transition between the
In an alternative exemplary illustrative non-limiting implementation, the camera location and the on-screen character position are fixed when the character is in this free-targeting mode (i.e. the player can move the targeting marker wherever desired). In this exemplary implementation, the character 504 is fixed in a lower left or right hand corner (e.g. one of the positions shown in
According to this implementation, if the player wishes to view a different portion of the world to select a target, the player uses a control other than that controlling the targeting marker (e.g. an analog joystick) to turn the direction in which the character faces. This allows the character to spin a full 360 degrees although the entire time the camera remains over the character's right shoulder (in this example).
In both of these exemplary implementations, the character continues to aim along a vector 505 passing through the character's 504 centroid and through the targeting marker 502.
As the game player continues to move the targeting marker 502 rightward, the targeting marker will eventually cross the line between the virtual camera position and the centroid of the virtual character 504. At this point, the virtual camera position automatically shifts again so the game player feels as if he is again viewing the 3D scene over the game character's right shoulder 508 rather than his left shoulder. This is shown in the transition between
a-12d show exemplary illustrative non-limiting displays of a character shifting from a “movement” mode to a “free targeting” mode. According to these exemplary implementations, a player controlled cursor 760 is shown flying in a position on the screen. In this exemplary implementation, the position of the cursor 760 can be changed using the same control that the player would use to move the targeting marker in the free targeting mode. Thus, for example, the player could preposition the targeting marker in the movement mode before switching into the free targeting mode.
a and 12c are the same exemplary displays, except that the cursor 760 has moved from the character's right side in 12a to the character's left side in 12c. According to this exemplary implementation, the relative position of the cursor to the character when the targeting mode is selected determines at which screen side the character is positioned. The
In this exemplary implementation, such a system allows the player to “pre-designate” which side of the screen the character will be set to, as well as which side of the screen will be shown, all through the use of a single input in the exemplary illustrative non-limiting implementation. For example, if two enemies are charging the player, from the left and from the right, but the right-most enemy is closer, the player can position the cursor over the closer enemy and trigger the free targeting mode. Since the perspective will shift so the character is placed in the lower left corner, the player has a clearer view of a wider area of the right half of the previous movement mode screen. The player can then target the closer enemy, kill it, shift back to movement mode, place the cursor over the remaining enemy and trigger the free targeting mode again.
Since in this exemplary implementation, the free targeting mode is triggered by the same button, regardless of the resultant character position, the player can worry less about designating the proper input to place a camera in one position or another and focus more on playing the game. The action becomes very intuitive. The player simply places the cursor over what he wishes to attack in movement mode, triggers free targeting mode, and the camera is automatically placed in a proper position allowing optimal view of the approaching designated target or designated area.
To determine which corner the character is rendered in, the system detects whether the displayed cursor is to the right of the character or not (decision block 614). While it would also be possible to subsequently determine if the cursor was to the left of the character or not, in this example it is assumed that if the cursor is not to the right of the character, then it must be to the left of the character. If the cursor is to the right of the character, the character is displayed in a lower left screen corner (block 616). Alternatively, if the cursor is not to the character's right, the character is displayed in a lower right screen corner (block 618). From either display, rotational input and/or targeting marker control are detected (block 620). Additionally, the system checks to ensure that targeting is still desired (decision block 622). If targeting is no longer selected at some point, then the system can return to display the character in a movement mode. As long as targeting is still selected, however, the system checks to see whether the character is in a lower left corner (decision block 624) and then branches to block 616 or 618 depending on the result, allowing a new check for different input.
a-16d show a plurality of exemplary third person viewpoints when a game is in a lock-on targeting mode according to an exemplary illustrative non-limiting implementation.
a shows an overhead view not necessarily seen in the game in this exemplary implementation but described here for purposes of illustration and clarity. A character 504 is displayed at a variety of positions B, C and D around a target dummy 702. According to this exemplary implementation, once the character 504 has locked-on to the target 702, the character can be freely moved within the game space. Here, the character is shown rotating from a position B where the camera 504 is looking over the character's right shoulder to a position C 90° away, to a position D almost 180° away. At each position B, C and D, the character 504 remains facing the target 702 and the character's weapon is aimed at the target along a vector (not shown) from the character's centroid through the target. While no targeting marker is provided according to this exemplary implementation, a marker 701 indicating the selected target may be shown, allowing the player to easily determine which target is locked in.
b shows an exemplary screen that might be shown if the character 504 is in position B. Here, the character is shown to the left and in the foreground with respect to the target 702. The marker 701 indicating target selection may also be shown.
c shows a second exemplary screen that might be shown if the character has moved to position C. Returning to
d shows a third exemplary screen that might be shown if the character has reached position D. Here the character is almost opposite the camera position, but has not quite reached 180° away. Now the target appears to be in the foreground relative to the character, and the character is about to pass behind the target. While the target is smaller in size than the character in this exemplary display, it would be possible for a character to be attacking a target that is much larger than the character. If this were the case, then the character moving behind the target could obscure the player's view of the character. Thus, in this exemplary implementation, when the character has reached position D, the camera begins to rotate around the target in the direction that the character is moving, and thus the screen shown in
Although the screen will typically maintain the display of
In the automatic camera positioning of this exemplary implementation, the camera's automatic following of the character at a point just before the character would be obscured allows the player to constantly see the character. Thus, instead of having to manually adjust the camera to show various perspective, the simple rotation of the camera to keep the player shown frees up the player's concentration of focus on attacking the enemy. Since this exemplary implementation also chooses a view that shows both character and target, players don't have to be concerned about selecting an improper camera view at a critical moment of a fight and thus being unable to see the character. Rather, by allowing game controlled camera motion, the player can rely on the game to show a proper and useful view.
a-17c show another plurality of exemplary third person viewpoints when a game is in a lock on targeting mode according to an exemplary illustrative non-limiting implementation. In these exemplary viewpoints, the player moves the character 504 from a position B′ to the left of a target 702 to a position C′ to the right of a target 702 across an invisible center plane 720.
b shows an exemplary initial position wherein the character 504 is at a position B′ to the left of a target 704. The character is shown from a perspective over the character's right shoulder by camera 750. Here, as the character moves towards a center plane 720, the camera 750 may move with the character, so as to attempt to prevent the character from passing in front of the camera and completely obscuring the target. Although the camera is moving with the character 504 in this exemplary illustrative non-limiting implementation, as the character 504 approaches a center plane 720 the camera 750 is moving slower than the character, so the character begins to obscure the target. Once the character 504 reaches the center plane 720, the character briefly blocks the target view and then passes over the plane 720. On the other side of the center plane, the camera 750 switches to a view over the character's opposite shoulder, placing the target 702 on the left and the character 504 on the right. This helps minimize character obstruction of the target, since the character is moving to the right and the target is now displayed on the character's left side.
In another exemplary illustrative non-limiting implementation, the camera 750 remains relatively fixed as the character 504 moves between the camera 750 and the target 702 towards the central plane 720. Since the camera can be place near the central plane, the character will still only obscure the view of the target for a short period of time before crossing the central plane, at which point the view would switch to the view from the other camera position, also near the central plane.
c shows an exemplary position where a character 504 has moved from position B′ to position C′ across plane 720. The camera 750 is now positioned over the character's left shoulder and shows the target 702 on the left side of the character 504. Such switching allows the player to move the character back and forth in front of the enemy and not have to worry about obscuring the enemy from view.
Also shown with
In this exemplary implementation, automatic camera decision making saves the player from being forced to manually switch a camera when the character crosses in front of a target. The scene would potentially appear awkward if the camera remained in a position over the character's right shoulder while the character was on the right side of the screen, since the target may then be obscured by some or all of the character's body. Instead of forcing the player to manually change the perspective, the camera simply keeps proper sight-lines established by switching shoulders over which it looks as the character crosses a center plane of the target. In this exemplary implementation the center plane is determined by the target, not the center of the screen, allowing the player to ensure that, because of camera swapping, the character should obscure the target for a very limited time, if any. This way, even if the target has moved away from the center of the screen, the player's view of it will remain correct as the character passes across a center plane of the target.
Since the camera makes correct automatic adjustments according to this illustrative implementation, a player can freely run back and forth in front of a foe and focus on the enemy, rather than on the camera-work.
a-18d show a plurality of exemplary viewpoints of a character shown by a camera when a player has ceased to direct a character motion in a particular direction. As shown in
In
b shows an exemplary scene of a forward “static” position of a camera. Here, the player presumably stopped moving the character while the character was in position F, which was within the forward grey area 722. Since the character was possibly obscuring part of the target in this position, the camera automatically shifts to position B″, thus showing the character 504 on the left side of the screen and the target 702 on the right side of the screen, with neither one obscured. The camera shift speed may depend on a variety of factors and can be varied as needed for a particular game.
c shows an exemplary scene of a “shift-free” zone, wherein the player can freely move and leave the character 504. Here, the character is closer to the camera than the target 702, and to well the left of the target. In this area, when the player stops directing character movement, the scene remains relatively the same (slight camera shifts may occur to account for terrain or other potential obstacles). The size of this zone can also vary with the relative character and target sizes, as well as varying with the proximity of the character to the target. For example, if the character were attacking a very small target at very close proximity, then position B″ and most positions from B″ to D″ might not be desirable as the character may obscure portions, if not all, of the target. In this instance, the camera may automatically shift to position D″, where the character and target are shown at opposite positions and a similar depth, to avoid possibly obscuring the target.
d shows an exemplary rearward “static” position of a camera. In this exemplary implementation, the player stopped moving the character while it was at a position E. Since the character was in the background at this point, the camera automatically adjusts to bring the character to an “even” position with the target, thus placing the character in the foreground again. This way, if a character is running behind a target to attack a tail or rear weak spot, and then the player desires to focus attention on attacking that area, the player can release the control designating movement around the target and have the view rotated such that a previously hidden rear portion of the target onto which the character was locked is now displayed oppositional to the character and in plain sight. Thus, if a target had multiple zones for attacking, the player could lock onto an appropriate zone and focus on moving the character into position for the attack and then release the movement designation control and focus efforts on attacking the now shown portion. These automatic camera shifts help keep the action and locked-on target visible to a player when the character is not maneuvering for position.
After displaying the character in initial position with the camera over the right shoulder (block 805), the game checks to see if the player directed character movement (decision block 806). If the player did direct movement, the game must then determine if the movement was rightward or not (decision block 808) (forward and backward movement do not generally cause camera movement in lock-on mode except zooms to prevent character from moving offscreen, although additional camera motion could be applied for these character movements).
If the character was moved right, the game displays the character moving to his right (block 810) and then checks to see if the character crosses over the central plane (decision block 812). If the character does not cross over the central plane, the game checks for continued movement indication (block 806), but if the character does cross over the central plane then the camera perspective changes and the character is shown moving to his right still (block 840), but with the camera now over his left shoulder and the target on the left side of the screen.
If the character was not moved right (at decision block 808) then the character is shown moving to his left (block 814). The game must then determine if the turning point was reached (decision block 816). If not, then the game returns to checking for movement (decision block 806). If the turning point was reached, then the camera itself begins to shift left around the target (block 818) as the character continues to move in that direction. This has the effect of causing the scene to rotate, preventing the character from moving behind the target (although the character can still be maneuvered behind the target, such maneuvering just may take extra work). As the camera is shifted (block 818) the game must also determine if the central plane has been crossed behind the target (decision block 820). If the plane has not been crossed, the game returns to detecting movement (decision block 806), but if the plane is crossed then the character continues to be displayed moving left (block 836) only from the other camera position, such that the target is now on the left side of the screen In this instance, since the character is opposite the camera and facing the camera, the target is on the screen's left side, while the character moves to his left (or the screen's right side).
If no character motion is detected at decision block 806, then the game must determine if the camera needs to be automatically moved to a better position. First, the game checks to see if the character is in a “shift-free” zone (decision block 822) (such as the exemplary zone between positions B″ and D″ shown in
Alternatively, after displaying the character in initial position with the camera over the left shoulder (block 830), the game checks to see if the player directed character movement (decision block 832). If the player did direct movement, the game must then determine if the movement was leftward or not (decision block 834) (forward and backward movement do not generally cause camera movement in lock-on mode except zooms to prevent character from moving offscreen, although additional motion could be applied for these movements).
If the character was moved left, the game displays the character moving to his left (block 836) and then checks to see if the character crosses over the central plane (decision block 838). If the character does not cross over the central plane, the game checks for continued movement indication (block 832), but if the character does cross over the central plane then the camera perspective changes and the character is shown moving to his left still (block 814), but with the camera now over his right shoulder and the target on the right side of the screen.
If the character was not moved left (at decision block 832) then the character is shown moving to his right (block 840). The game must then determine if the turning point was reached (decision block 842). If not, then the game returns to checking for movement (decision block 832). If the turning point was reached, then the camera itself begins to shift right around the target (block 844) as the character continues to move in that direction. This has the effect of causing the scene to rotate, preventing the character from moving behind the target (although the character can still be maneuvered behind the target, such maneuvering just may take extra work). As the camera is shifted (block 844) the game must also determine if the central plane has been crossed behind the target (decision block 846). If the plane has not been crossed, the game returns to detecting movement (decision block 832), but if the plane is crossed then the character continues to be displayed moving right (block 810) only from the other camera position, such that the target is now on the right side of the screen In this instance, since the character is opposite the camera and facing the camera, the target is on the screen's right side, while the character moves to his right (or the screen's left side).
