Using UndelphiX again.

[User137]

Have you enabled the timer? Do you see any animation on screen if you try?

edit: Oh you said you did. Need more actual source code or something more to give more hints then.

Also the way i used DelphiX back then was with DXImagelist1.Items.Find('mytexture').Draw(Surface, X, Y, pattern); (might have forgotten the syntax). So you could say nxpascal is a predecessor to it in a sense. Now i do the same with:
tex.SetByName('mytexture');
nx.Draw(X, Y, pattern);

So if you're looking for something modern, and much faster than DelphiX, you can give it a try
