Is there any way to achieve alpha blending effects in BlitzPlus? Thanks.

Extended Blitz 2D should work.

There's also another DLL around that can give you fast alphablending in blitzplus, but for the life of me I don't recall what it was called....

And there's some old posts floating around mentioning sswift's BOB system which apparently can do transparancy... He released it for free some time ago, but the free download link posted to the forum at the time no longer appear to work. See a demo + contact info here:

Here's a couple links from the code archives.

There's another called "drawAlphaImage2" somewhere in the archives.

The comment said its pretty slow so I'd take his word.

Didn't work for me when I tried it but I'm going to try it again.
