I'm not sure if this is outside the bounds of what this board covers, but I figured I'd ask.
I want to be able to achieve spell effects that cause a fragmenting/discoloring effect on the sprite. The first couple seconds of shows what i meant. When the enemy get's hit by an electric attack, the effect I'd like to achieve activates (in yellow).
I'll have to use shaders to do this (if I don't, other, practical ways to do it would be extremely helpful). I have no idea where to start with a shader like this (beyond the obvious - using time and base color as parameters), and was curious if someone had something similar I could use as a base, or had a good idea where to start. I know the basic of glsl, but was hoping to spare myself some pain if someone has something like this already or could provide a starting point.
Any help would be appreciated,
