And also i have learned using DrawingBuffer & DvrawingBufferPitch.
looks like an easy water-mirroring
Code: Select all
If InitSprite() = 0 Or InitKeyboard() = 0
MessageRequester("Error", "Can't open DirectX 7 Or later", 0)
End
EndIf
If InitSprite3D() = 0
MessageRequester("Error", "Direct3D system can't be initialized correctly", 0)
End
EndIf
