Missile creation help

[Moon_Raven]

Ok I want to make an ability that works like this: It shoots a rock(like a missle) and you can target both ground and a unit. If ground is targeted, the missle doesn't just explode on the point, it goes through the point you clicked on and travels beyond. I've tried to make this ina couple of ways but it doesn't work. Can somebody help me please? Also, the point of missle is that if it comes in a range of (something) of enemy unit, the enemy unit is killed.

this sounds very much like Elunes Arrow in "The-Map-That-Must-Not-Be-Named".

anyway here is a GUI version made by Naminator though it should be said that his version is neither MUI nor MPI. (but maybe you don't need it to be.)
