I have been playing with the new sprite functions and here is a rough version of a simple demo, it needs more logic and some collision of sprite to sprite and sprite to background.

Enjoy

That is very nice Michael. Thanks for the present.

The only problem I see in the example is CPU usage that is too high I suppose because using WHILE/WEND loop. If it could be converted to callbacks and timer it would really fly.

Ciao and thanks again.

Hi Michael,

that is very nice demo!

If you want to let it in window and still have low CPU use, instead of:


while TBGL_isWindow(hWnd)
' -- Rendering code here
wend


you can use "periodical" function mechanism:


' -- Specify which function will take care of rendering, and how often
TBGL_BindPeriodicFunction(hWnd, "Do_GameLoopFunction", 15) ' -- 15ms timeout

' -- Here it halts rendering and starts calling Do_GameLoopFunction each 15ms if possible
TBGL_ProcessPeriodicFunction(hWnd)

' -- Once TBGL_UnBindPeriodicFunction is called, we get here

...

SUB Do_GameLoopFunction()
' -- Rendering code here
If TBGL_GetWindowKeyState(hWnd, %VK_ESCAPE) Then TBGL_UnBindPeriodicFunction( hWnd )
END SUB


It should kick CPU usage down to almost zero. Internally it is timer based.

Thanks guys

I will do a rewrite when time allows and add some more, it was from the sprite sample.


thanks for your help as always

Quick update I have used Petr's timing and it has gone down to 0 seconds but I wont release a new version until i've add more features.
Does looks quite good in full screen from a distance, so I will add an option to do that.
