SpriteInCamera

Flag = SpriteInCamera(SpriteIndex, CameraIndex)

Parameters:     SpriteIndex = The Index of the sprite you wish to query     CameraIndex = The Index of the camera you wish to check this sprite against

Returns:     Flag = The state of this sprite (0= outside of camera, 1 = inside of camera)

The SpriteInCamera functions check if a sprite position is within the viewport of a camera. FACTS:       * This compares the world space position of the sprite to the camera.       * See CameraBasics, CreateCamera Mini Tutorial:       This example is really 4 parts. Part1 creates an image. Part 2 creates some randomly positioned sprites using the previous created image. Part 3 Creates a camera, while Part 4 is the main process loop, which lets the user control the camera, and thus displaying the (SpriteinCamera) status of each sprite.    ; ======================== ; Part 1 - Create an image ; ========================      Cls RGB(0,255,255)   GetImage 1,0,0,32,32       ; ============================= ; Part 2- Create some sprites ; =============================    ; Create a bunch of randomly positioned sprites   For Sprites=1 To 10      CreateSprite Sprites      SpriteImage Sprites,1    ; Randomly position them      PositionSprite sprites,Rnd(1000),Rnd(1000)   Next          ; ============================= ; Part 3- Create a camera ; =============================      CreateCamera 1   w=GetScreenWidth()-32   h=GetScreenHeight()-32   CameraViewPort 1,32,32,w,h       ; ============================= ; Part 4- The Main Loop ; =============================      MakeBitmapFont 1,RGB(255,255,255)    ; Start a DO/Loop   Do    ; Clear the screen      Cls RGB(0,0,255)          ; Tell PB to capture all future GFX commands    ; to the scene buffer, rather than draw them      CaptureToScene          ; Clear the scene buffer      ClsScene          ; Controls for moving the camera      If UpKey() Then MoveCamera 1,0,-5      If DownKey() Then MoveCamera 1,0,5      If LeftKey() Then MoveCamera 1,-5,0      If RightKey() Then MoveCamera 1,5,0          ; Draw All of the sprites to scene buffer      DrawAllSprites          ; Draw the Camera      DrawCamera 1          ; Cycle through the sprites and display if their    ; in view of the camera Or Not            For Sprites=1 To 10         s$="Sprite "+Str$(Sprites)+" is in camera:"         If SpriteInCamera(Sprites,1)=true            s$=s$+"Yes"         Else            s$=s$+"No"         EndIf         Print s$      Next          ; Draw the screen      Sync          ; Loop back to the DO statement   Loop    This example would output.
