+1.

Should be made optional.

Why should a RotateSprite3D x, y?
The rotation of sprites always looks the same.
The shift comes at DisplaySprite3D.
There, the x and y:

Code: Select all

x+Cos(Angle)*dx-Sin(Angle)*dy
y+Sin(Angle)*dx+Cos(Angle)*dy

Where dx and dy represent the displacement then.

Here a result:

Code: Select all

InitSprite()
InitSprite3D()

OpenWindow(0, 0, 0, 800, 600, "SCREEN", #PB_Window_SystemMenu|#PB_Window_ScreenCentered)
OpenWindowedScreen(WindowID(0), 0, 0, 800, 600, 0, 0, 0)
 
 CreateSprite(1, 256, 256,#PB_Sprite_Texture)
 StartDrawing(SpriteOutput(1))
  Box(0,0,128,128,$FF0000)
  Box(128,0,128,128,$00FF00)
  Box(0,128,128,128,$0000FF)
  Box(128,128,128,128,$00FFFF)
 StopDrawing()
 CreateSprite3D(1,1)
 
Repeat

 Event = WindowEvent()

 ClearScreen(0)

 Angle.f+0.02
 
 Start3D()
 
  RotateSprite3D(1, Degree(Angle), 0)
  DisplaySprite3D(1, 128, 128) ; no shift, roate at center
  dx = 128 : dy = 128 ; Shift to a corner
  DisplaySprite3D(1, 384+Cos(Angle)*dx-Sin(Angle)*dy, 128+Sin(Angle)*dx+Cos(Angle)*dy) ; with shift
 
 Stop3D()

 FlipBuffers()

Until Event = #PB_Event_CloseWindow

Interesting and thanks for posting. But I think I would still prefer the request. As I think it would fit the command.
