Script for making a explosive?

[SayWhatOneMoreTime]

I'm trying to make a explosive type thing but I don't know what I need to make it, I know you need slade and I already have that and I already have the sprites done but I just need to know how to make the throwing animation and the script that I can use for it to work as a grenade.
