Spawning animated decal/effect

You have to make an animated material and use that material on your decal.
A place to start:

Basically I’m trying to make an animated 2d decal that spawns on a wall after impact. (Here is the look I’m going for TRON: Legacy Clip - Disc Wars - YouTube)

I’m not quite sure how to create this effect with a decal?

At first I made a hit effect particle emitter that looks good, but when I spawn it on the wall, obviously it’s going to be 3D and not really flat/flush with the wall.

How can I create an animated effect like that with a decal? Or some other way of having an animated 2d hit effect on a wall? Is there a way to turn the emitter visuals into a decal?
