A"SAFE" haven

[gudson]

im using a spell that involves triggers called haven, it creates a protective barrier for allied units to keep enemies out but ranged units can still attack units inside the haven, i want to prevent this but am not sure how, i dont want units inside the haven attacking either. Ive got some ideas on how to fix this, making units invisible or invulnerable, but im not sure how to make it happen. any help is greatly appreciated.

This is the spell

Spoiler:

Based on your natural offset of your "rotating orbs" at a offset of 400 range, I based my triggers off that assumption that you neither want or want units attacked/attacking from in that aquired area. Thus, these triggers arose...

Prevent Attacking
Events
Unit - A unit Is attacked
Conditions
Or - Any (Conditions) are true
Conditions
((Attacking unit) is in (Units within 400.00 of havenpos)) Equal to True
((Attacked unit) is in (Units within 400.00 of havenpos)) Equal to True
Actions
Unit - Order (Attacking unit) to Stop


Prevent Ability
Events
Unit - A unit Begins casting an ability
Conditions
Or - Any (Conditions) are true
Conditions
((Casting unit) is in (Units within 400.00 of havenpos)) Equal to True
((Target unit of ability being cast) is in (Units within 400.00 of havenpos)) Equal to True
Actions
Unit - Order (Casting unit) to Stop

The map is tested and fully functional, Gl hf. Credits always a bonus.
