I am working on a defense map that requires triggers to create interceptors with adjusted HP/SP percentages and send them along a path.

How do I get the triggers to create the interceptors, and if it is any different, how do I order them to do things?

Always wanted to say that
Ordering interceptors

First, you can't directly create an interceptor with a trigger. You need a carrier. When you have the carrier(s), place a target so they will attack, make a trigger to move the interceptors where the carriers are, to the location you want. If you want me to explain everything, I'd be happy to, but I need your answer. Anyway here's an article about it: http://www.staredit.net/wiki/Ordering_and_Using_Interceptors/Scarabs
As I said, if you need my personal help I would make a test map too if you want.

Thank you very much, Lethoth. You've been of great help!

I'm glad I can help, so will you need a test map or anything else?

I like to mess with triggers myself, find out how they work for myself and such.
I just know I've seen maps using them in that manner and I couldn't get it working right.
From what I knew and what I got from 5 seconds of reading that wiki, it's working

Thank you again!
