with subsystem opengl ScreenOutput() = 0

Hi,

ScreenOutput() returns null with subsystem opengl:

Win = OpenWindow(#PB_Any, 100, 100, 195, 260, "PureBasic Window", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)

Debug InitSprite()
Debug OpenWindowedScreen(WindowID(Win), 10, 10, 50, 50, 0, 0, 0)
Debug ScreenOutput()

Repeat
Until WaitWindowEvent() = #PB_Event_CloseWindow

Its because you cannot do 2ddrawing on a screen with opengl.

Uh...

so it's impossible to use Sprite3D and 2DDrawing in the same application...

In my game, I don't use 2DDrawing commands. I need the ScreenOutput() and SpriteOutput() only to identify the memory adress of the screen/sprite for manipulation with CopyMemory, Peek/Poke and Pointers. It's possible to identify the memory adress of a screen/sprite and the pixel format without 2DDrawing library?

Her is my old code:

Code: Select all

  StartDrawing(ScreenOutput())
    ScreenFormat = DrawingBufferPixelFormat()
  StopDrawing()

  StartDrawing(SpriteOutput(SourceSprite))
    SourceAdress = DrawingBuffer()
    SourceRowLen = DrawingBufferPitch()
  StopDrawing()

  StartDrawing(SpriteOutput(DestinSprite))
    DestinAdress = DrawingBuffer()
    DestinRowLen = DrawingBufferPitch()
  StopDrawing()
