I was experimenting with the particle emitter. This is a freaking magical wall!
It has a collision shape with it.
Emmission rate: 225
Gravity: -40
Colors: Blue
I wanted to create a magical wall like in WoW, but oh well, this ain't bad.
You can change the height, width, color or direction of the wall if you want.
edit 1: centered; Death animation nothing.
