AOE Polymorph without CasterSystem?

Is there a way to make an AOE Polymorph without using the CasterSystem?
Like when a mine dies, itll make all the unit within 300 range of the mine, become Polymorphed

If you could help id appreciate it! =] Sorry for all the spell help posts =/

Just make a unit group for the units in the area targeted, and create a dummy unit to cast polymorph for each one.

There's a Jass tutorial on here that actually uses mass polymorph and mass slow as examples and has walk-through for them.

I was looking around and i didnt see the tutorial, Do you know where the tutorial is?

It is like the oldest trick in the book, pick every unit in (Units within 500 of (Dying unit ) and do:

-Create dummy unit on position of (picked unit)
-Order last created unit to polymorph (picked unit)
-- make sure the dummy unit has a castable polymorph --
- Add expiration timer to dummy unit

Alright thanks Vexorian!
+Rep for the help =]
