Re: [pygame] Why does my ball vibrate?

a while ago someone said that the ball speeding up and slowing down "randomly" was because it was based on the time elapsed every frame and that time varies because if other tasks are being run then the cpu is executing both threads so it doesn't spend all of its time in your game. But then what w

I always wondered how the ball in Pong could bounce indefinitely, and not acceler

I did also manually put the font into library.zip. Still had the same problem. Then I took the suggestion from another post and explicitly loaded the freasnsbold.ttf font, instead of using None (and getting the default.) That worked, but all my fonts rendered about 50% bigger than before. Stra

Re: [pygame] Problems with py2exe and Pygame

Hi, you can use the datafiles option in your setup.py to copy the font. Maybe take a look at my setup.py script: http://schoolsplay.svn.sourceforge.net/viewvc/schoolsplay/branches/childsplay_sp/windows/setup.py?view=markup It's fairly straight forward. Chris On Dec 5, 2007 2:15 AM, Patrick Mull
