Looking for a script to make spells with, please help!

I need a script that causes a particle burst on collision. I'm making a set of invisiprim shots from the hand that sticks to it's impact point. But here's the problem: I have no particle on collision script to make an effect of being hit with it. Now, I don't want much from it, just a templatethat allows me to edit it's colors size, effects, etc. the basics, you know? I will pay you 50L for it, if you are so inclined and if it is allowed on here. if not, disreguard the price lol

This should be about what you want I think. This script has not yet been compiled, so it may need a minor syntax fix or two, but it is based on a template I use for all particles, so it shouldn't have too many issues.

float BURST_DURATION = 1.5;

particlesOn()
{
