Ability Area Effect

[PsychoMagnataur]

How do I change the target of an ability from single unit to area to radius?
How? Please tell me!

You can't. You'll have to find some other way to do what you're doing.

That sux...

 

[Eusira]

What are you basing if off of?

 

[PsychoMagnataur]

I wanna make either Ensnare or Aerial Shackles hit every enemy in an area.

 

[Eusira]

Ensnare is easy. Create an invisible dummy with a no-cooldown ensnare

Unit starts effect of an ability
Condition
Ability being cast equal to mass ensnare
Actions
Shift control of dummy 001 to Owner of triggering player
Move dummy 001 to position of triggering unit
Pick every unit within 500 of Target unit of ability being cast an do- Order dummy 001 to Neutral-Ensnare Picked unit

That's a perfectly functional trigger, although the mechanics of unit groups and locations means that it will be pretty memory-leaky. If cast often, it may cause the game to lag and will likely cause a long garbage-collection period at the end of the map.

However, doing it with jass variable destruction and locals is substantially more difficult, so if this one works well, I'd advise you to use it.
