Re: [Plib-users] Buiding Sky using the functions in ssgaSky

[Michael W. <mic...@ti...>]

Hi Nick,
I have tried the sky example and it runs well.
The difference in my code is, that the function sky->build(...) is called in
a different file as the function sky->preDraw(() .

If I'am using the functions init_graphics and redraw of the example sky in
my code.Tthe scenery with the sky is rendered then well but in another
window than my simulation is running.

Where comes the problem from?

Best regards
