Re: [pygame] groups drawing optimization

["René Dudfield" <renesd@xxxxxxxxx>]

Hi,

depending on how you've done it, it could be skipping those things
anyway.  This is because a surface does not draw stuff outside of it's
area... things get clipped.

However it may be worth doing, if you can calculate what not to draw
quickly enough.

Another trick is not running the AI for things off screen too.
Depending on your game that could work too.

cheers,
