Blitz3D Lesson4 Error

| Hi, I seem to have messed up the lesson4.bb file, because Blitz3d demo does not undo changes, unfortunately, and it also apparently auto saves the file, so now the file is messed up. However, I had created my own file, as I followed the lessons. I am getting this error: Memory Access Violation, and can't get it fixed. Can someone help please. Here's the code: ; Variables Global escape_key = 1 ; scancode for ESCape key is 1 - Store it's value in a Global variable we'll name "escape_key" Global screenW = 640, screenH = 480 ; create a Global variable for the game screen ; Running sound effect handle and volume tags Global run, run_vol#, runchannel Graphics3D (screenW,screenH,32,2) ; 32 bit color depth ; windowed ; Running fullscreen can speed up your game significantly in many cases. SetBuffer BackBuffer() ; AmbientLight 200, 200, 200 ;add some Ambient light so that if the player gets too far from the point light source things won't go dark Global myLight_01 = CreateLight(2) ; creates a standard point light. (1 = directional (Default) , 2 = point, 3 = spot) ; create single camera Global myCam_01 = CreateCamera() ; creates a camera CameraViewport (myCam_01,0,0,screenW,screenH) ; sets up the view of th camera. This 'sees' the entire game screen. ; Load/Use sprite functions Include "spriteLoader.bb" ; Load/Use sound functions Include "soundFunctions.bb" ; INSERTS "soundFunctions.bb" file ;FUNCTIONS LoadMusic() LoadSFX() ; Load world randomly with "tree" sprites using our NEW reuseable LoadRandomSprites() function ; Just give the sprite image, how many, and the X and Z range for random placement! LoadRandomSprites ("tree.bmp", 500, -250, 250, -250, 250) ; call function ; Run a loop as long as no escap key is not pressed - so that I can see what happens While Not KeyHit(escape_key) ; Use the sprite "RUN" sound volume to toggle sprite animation If (run_vol# > 0) Then AnimSprite (sprChar, sprCharAnim_tex, 200, 4) ; execute function UpdateWorld RenderWorld Flip Wend End |
