I'm sure a lot of you have played the game Quake 2 and used the Railgun. When shooting the railgun it gives a cool spiral effect. I wanted to know if it was possible to create a similar effect with a bunch of temporary entities (or a better method).
or...
Would it be possible to make one sprite give that same effect?
If you have never saw the quake2 railgun effect before then you can checkout these screenshots.
