Hi again,

The problem is you used zero as parameter to the RenderWorld() function ... try 1 instead. Thanks Floyd for pointing this out in the mirror thread.

This works (converted to PureBasic):


IncludeFile "blitz3dsdk.pbi"


Procedure main()
  bbBeginBlitz3D()
  
  bbGraphics3D(640, 480)
 
  
  cube = bbCreateCube(0)
  light = bbCreateLight(1, 0);
  camera = bbCreateCamera(0);
  
  sphere=bbCreateSphere(16)
  bbEntityColor(sphere, 255, 0, 0)
  bbPositionEntity(sphere, 0, 0, 300)
  bbscaleentity(sphere, 100, 100, 100)

  bbPositionEntity(camera, 0, 0, -4, 1);

  bbEntityAlpha(cube, 0.5); // as i understand this line should make the cube transperent ... it dosent.

  While Not bbKeyHit(#KEY_ESCAPE)
    bbUpdateWorld(1);
    bbRenderWorld(1);
    bbTurnEntity(cube, 0.1, 0.2, 0.3, 1);
    bbText(20, bbGraphicsHeight() - 20, "Blitz3DSDK C# Example (C)2007 Blitz Research 2007", 0, 0);
    bbFlip(1);
  Wend
  bbEndBlitz3D()
EndProcedure

main()

On a sidenote, don't crosspost between forums, please.
