I’m new to shaders and trying to learn but i need to get something done and don’t find any tutorials on that.

i need a glowing shader for a 2D game that kind of looks like this:

(sorry for this gigantic monstrocity of a link)

the only thing i know about shaders is how to make they move their vertexes (up, down, left and right) and paint them with different flat colors :S i have no idea of how to do this effect.

There are a lot of ways such as setting the render to unshaded and using the fragment function and changing the alpha value higher and lower.
or tampering with the light function.

but the quickest is modifying someone else’s code :slight_smile:

Thank you :smiley:

helped a lot, the alpha tip was killer!
