"""This examples demonstrates a simplish water effect of an
|
||
|
|
image. It attempts to create a hardware display surface that
|
||
|
|
can use pageflipping for faster updates. Note that the colormap
|
||
|
|
from the loaded GIF image is copied to the colormap for the
|
||
|
|
display surface.
|
||
|
|
|
||
|
|
This is based on the demo named F2KWarp by Brad Graham of Freedom2000
|
||
|
|
done in BlitzBasic. I was just translating the BlitzBasic code to
|
||
|
|
pygame to compare the results. I didn't bother porting the text and
|
||
|
|
sound stuff, that's an easy enough challenge for the reader :]"""
