Re: [sdljava-users] EventManager: using pollEvent() instead of waitEvent() ?

[Patric R. <pa...@ma...>]

It isn't a real problem. SDL_WaitEvent() has to use a loop, too.

As you can see in the source:

int SDL_WaitEvent (SDL_Event *event)
{
	while ( 1 ) {
		SDL_PumpEvents();
		switch(SDL_PeepEvents(event, 1, SDL_GETEVENT, SDL_ALLEVENTS)) {
		    case -1: return 0;
		    case 1: return 1;
		    case 0: SDL_Delay(10);
		}
	}
}

I think, it would be best to maintain the original timings and sleep for 
10 ms.
