Ogre3D - OpenGL - Sprite

EDIT: Missed CreateCamera, which was the reason for lack of sprites ...

Code:

;InitEngine3D()
InitSprite()
InitKeyboard()

OpenWindow(0,  0, 0, 300, 300, "OpenGL Sprite", #PB_Window_ScreenCentered|#PB_Window_SystemMenu)
OpenWindowedScreen(WindowID(0), 0, 0, 300, 300)
CreateCamera(0, 0, 0, 100, 100) ;<--- Duh!
CreateSprite(0, 50, 50, #PB_Sprite_AlphaBlending)
StartDrawing(SpriteOutput(0))
DrawingMode(#PB_2DDrawing_AlphaBlend)
Circle(25, 25, 20, $FF00FFFF)
StopDrawing()
Quit = #False

Repeat
  Repeat
    ev = WindowEvent()
    If ev = #PB_Event_CloseWindow : quit = #True : EndIf 
  Until  ev = 0
  RenderWorld()
  DisplaySprite(0, 0, 0)
  FlipBuffers()
  ExamineKeyboard()
 
Until  KeyboardPushed(#PB_Key_Escape) Or quit = #True

I get the same outcome.

Bug confirmed for the following configuration:
Windows 7 x64, PB 5.72 b1 x64 OpenGL subsystem.

For me it is already sufficient to uncomment the first line: InitEngine3D(). Then the sprite is no longer displayed.

it's important to fix this bug because the future versions of PB will integrate shaders that work everywhere only in opengl

Bug confirmed here for Windows 10, PB 5.72 x86 OpenGL

There is no bug in Windows 10, PB 5.72 x86 DirectX

For debbuging:
With Windows XP32b + pb 572b2x86:
No bug with opengl :!:

But i've got a bug with directX+InitEngine3D()+RenderWorld() , the yellow thing is displayed but the screen flickers a lot.

with "CreateCamera" it works

Code:

InitEngine3D()
InitSprite()
InitKeyboard()

OpenWindow(0,  0, 0, 300, 300, "OpenGL Sprite", #PB_Window_ScreenCentered|#PB_Window_SystemMenu)
OpenWindowedScreen(WindowID(0), 0, 0, 300, 300)
CreateSprite(0, 50, 50, #PB_Sprite_AlphaBlending)
StartDrawing(SpriteOutput(0))
DrawingMode(#PB_2DDrawing_AlphaBlend)
Circle(25, 25, 20, $FF00FFFF)
StopDrawing()
CreateCamera(0, 0, 0, 100, 100)
 
Repeat
  Repeat
    ev = WindowEvent()
    If ev = #PB_Event_CloseWindow : quit = #True : EndIf
  Until  ev = 0
  RenderWorld()
  DisplaySprite(0, 0, 0)
  FlipBuffers()
  ExamineKeyboard()
 
Until  KeyboardPushed(#PB_Key_Escape) Or quit = #True

but with a screen the programme crash

Code:

InitEngine3D()
InitSprite()
InitKeyboard()

OpenScreen(1280,720,32,"")
CreateSprite(0, 50, 50, #PB_Sprite_AlphaBlending)
StartDrawing(SpriteOutput(0))
DrawingMode(#PB_2DDrawing_AlphaBlend)
Circle(25, 25, 20, $FF00FFFF)
StopDrawing()
CreateCamera(0, 0, 0, 100, 100)
 
Repeat
  RenderWorld()
  DisplaySprite(0, 0, 0)
  FlipBuffers()
  ExamineKeyboard()
 
Until  KeyboardPushed(#PB_Key_Escape) Or quit = #True

"startdrawing la sortie est specifiée est null"

another clue:
a piece of the 3d scene is sometimes displayed in the sprite. there is obviously a memory corruption.

config : PB 5.72, Windows 10 Famille
