""" pg.examples.testsprite
|

|
|
|
||
|
|
Like the testsprite.c that comes with libsdl, this pygame version shows
|
||
|
|
lots of sprites moving around.
|
||
|
|
|
||
|
|
It is an abomination of ugly code, and mostly used for testing.
|
||
|
|
|
||
|
|
|
||
|
|
See pg.examples.aliens for some prettyier code.
