Flip Sprite ???

Is it possible to have something like FlipSprite or Mirror sprite function ? All OS
Or at least something to invert the 3D sprite polygon so it doesn't disappear when you try to flip it using the TransformSprite function.

but only optional, like TransformSprite(Sprite, x1, y1 ..., z4[, ShowBackSide]), I have written a small 3D-Engine with TransformSprite(), and I don't want to see the back side of my Sprites
.
But yes, it would be nice to flip a Sprite with ZoomSprite(Sprite, -256, 256) or with ClipSprite(Sprite, 100, 0, -100, 100).

Another possible solution also could be is to have access to the polygons normals.

I don't understand why not always simple solution to enable/disable backface culling when use transformsprite (All Os)

I found this way for 5.20 on windows.
press space to flip sprite
InitSprite()
InitKeyboard()
OpenWindow(0, 0, 0, 800, 600, "", #PB_Window_SystemMenu | #PB_Window_MinimizeGadget | #PB_Window_MaximizeGadget | #PB_Window_ScreenCentered)
OpenWindowedScreen(WindowID(0),0,0,WindowWidth(0),WindowHeight(0))
;Disable Backface Culling

; thanks Innesoft
Define pd3d.IDirect3DDevice9
EnableASM
!extrn _PB_Screen_Direct3DDevice
!MOV dword EAX, [_PB_Screen_Direct3DDevice]
!MOV dword [v_pd3d],EAX
DisableASM
pd3d\SetRenderState(22,1)
pd3d\SetRenderState(7,0)
;-create sprite
CreateSprite(0,128,128)
StartDrawing(SpriteOutput(0))
Circle(32,32,64,#Red)
Box(64,32,64,32,#Green)
StopDrawing()
Repeat
Repeat
Event = WindowEvent()
Select Event
Case #PB_Event_CloseWindow
End
EndSelect
Until Event=0
ExamineKeyboard()
ClearScreen(#Black)
If KeyboardPushed(#PB_Key_Space)
TransformSprite(0,SpriteWidth(0),0,0,0,0,SpriteHeight(0),SpriteWidth(0),SpriteHeight(0))
Else
TransformSprite(0,0,0,SpriteWidth(0),0,SpriteWidth(0),SpriteHeight(0),0,SpriteHeight(0))
EndIf
DisplaySprite(0,32,32)
FlipBuffers()
Delay(1)
ForEver
But i have no solution for Linux/MacOsX

Yes, but it's very slow and you must to copy the orginal sprite ...
it is a shame not to use the hardware facilities

Yes, that is a shame. After 14 years PureBasic there is no function to mirror a sprite in an easy way...
The workaround with TransformSprite, is this possible with Win, Mac and Linux?

Damn.
Its not working for me. When i hit the spacebar it blank out the screen. Or maybe i see the backside of the sprite.
I am using PB 5.62 on a win 8.1 system 16 Gb mem,i7 core intel(64 bits). Nvidea Geforce 950m
There must be something i miss.
