hey, does this CameraProject thing work fine? even a simple test with CameraProject(cam,10,10,10) print ProjectedX() returns #QNAN000 whats the problem here? i use minib3d 0.53 and the last smallfix thingy (the one from february 2010)

I just adapted Blitz3D CameraProject sample to miniB3D, and here it works without any problem. Import sidesign.minib3d '; CameraProject Example '; --------------------- Graphics3D 640,480,0 Local camera:TCamera=CreateCamera() PositionEntity camera,0,2,-10 Local light:TLight=CreateLight() RotateEntity light,90,0,0 Local cube:TMesh=CreateCube() EntityColor cube, 255,0,0 PositionEntity cube,0,1,0 While Not KeyDown( KEY_ESCAPE ) If KeyDown( KEY_LEFT )=True Then TurnEntity camera,0,-1,0 If KeyDown( KEY_RIGHT )=True Then TurnEntity camera,0,1,0 If KeyDown( KEY_UP )=True Then MoveEntity camera,0,0,-0.05 If KeyDown( KEY_DOWN )=True Then MoveEntity camera,0,0,0.05 '; Use camera project To get 2D coordinates from 3D coordinates of cube CameraProject(camera,EntityX(cube),EntityY(cube),EntityZ(cube)) RenderWorld '; If cube is in view Then draw text, If Not Then draw nothing otherwise text will be drawn at 0,0 If EntityInView(cube,camera)>0 Then Text ProjectedX(), ProjectedY(), "Cube" EndIf Text 0,0,"Use cursor keys to move about" Text 0,20,"ProjectedX: "+ProjectedX#() Text 0,40,"ProjectedY: "+ProjectedY#() Text 0,60,"ProjectedZ: "+ProjectedZ#() Text 0,80,"EntityInView: "+EntityInView(cube,camera) Flip Wend End Try this code and see if it works...

ty slotman, that worked, and helped me to find the problem. for any reason it was not working when i did "self.camera = CreateCamera(self.pivot)" inside a method of another object. maybe its a thing with include stuff or something.
