Yes, I'm making a LUA script. And it's simple. How do I modify an existing ability through LUA? Specifically the homing attack.

Well, it sorta depends on your intentions, but for the most control, generally, you'll have to recode the entire move based on the source code, then edit it. It's what I did for my Air Drill edits.
