[Gamecode]

hi
i need combine one clasics texture and one alphamap into one tex.and this texture then draw with screen2d.drawtexture.

see screen.

Code:

int source = TF.LoadTexture("\\media\\texture.jpg");
int alpha = TF.LoadAlphaTexture("\\media\\alpha.jpg");
int combined = TF.AddAlphaChannel(source, alpha, "combined");

that's C#, but i'm sure you can change that

[Gamecode]

Code:

int source = TF.LoadTexture("\\media\\texture.jpg");
int alpha = TF.LoadAlphaTexture("\\media\\alpha.jpg");
int combined = TF.AddAlphaChannel(source, alpha, "combined");

that's C#, but i'm sure you can change that

great thanxs.
and if i need rotate with alphamap ? must on every frame create new "combined" texture ?

no, the combined one is just a normal texture with an alpha channel, so you can rotate that texture just like you would rotate any other texture. I don't know if it's the same if you just want to rotate the alpha channel, that's different i guess.

no i need base texture in same position (0 degrees) and rotate only with alpha chanel

I wonder: can in the AddAlphaChannel funcion, can you pass a rendersurface texture to the alpha argument? If so, then you couls render your rotated alpha texture to the rendersurface. Don't know if this is legal though.

This is awesome! thanks a bunch!

and yes, you can pass a rendersurface as a texture:
