If you insist.
I should have stated that the source program (for "Cowboy Shootout") comes with the GFXLIB package, whereas the ZIP folder (cowboyshootout.zip) contains only the compiled executable.
The GFXLIB package contains an updated (i.e. slightly better) version of Cowboy Shootout.

I've been working on a new bitmap rotation routine for GFXLIB.
Despite still partially being in BASIC(!), this one is significantly faster than "my old one",
and yet it's still very far from optimal. In fact, until I can get my Sutherland-Hodgman polygon clipper
working properly, this routine will remain very inefficient.
Here's a preview:

Use the left and right mouse buttons to zoom in and out.
David.

New routine (alpha-blend with master opacity control) as recently requested by a BB4W user who's developing a GFXLIB-based game.
Here's a quick demo of PlotAlphaBlend4:
http://www.bezu.co.uk/filesdump/temp/progs/plotalphablend4demo.zip
Notice the nice smooth sprite edges? Use the left/right arrow keys to decrease/increase the number of sprites.
This routine will be included in the next release (v2.02) of GFXLIB due out in a month or three.
David.
