sprite alpha?

[Mr. Strange]

Since the concept of an alpha channel is supported in the "color" functionality, I suspect that I can designate a color to act as an alpha mask for my sprites. Or maybe there is a color already designated as an alpha mask? In either case, I'm at a point where I'm applying complex sprites, and I need my alpha. Could someone point me to the syntax I need?

You can't choose a color as an alpha mask, no. (This question is almost FAQ-worthy by now). You can use the built in alpha channel in image files like .png or .tga. What looks transparent in your image editor will become transparent in LÖVE.

On a related note, you can also modulate the general color of an image with the current color. This is useful if you want change the the total alpha of the sprite, for instance to fade an image in/out. See love.graphics.setColorMode.

Alright, I grabbed the beta for pixelformer, and saved my images as rgba. Works fine!
