That would probablity work, I am wanting to make the conyard to make base repairs, like in Renegade. Is there a way for a building to automaticly target your structures?
You could try giving it a weapon that fires and deals negative damage and maybe even give it a tag that gives it like a 'guard' logic (i.e., Repair IFV's automatically repair vehicles in their guard range). That might work, but it woun't work as a superweapon.
IFV-Repair only works on VehicleTypes, and MedicHeal only works on infantry - yet it is unlikely that similar stuff works with buildings, since building-repair is a special logic...
As usual, it might work with a particle, though.
Also, something similar to the power on+off SW might work, and abuse is rather improbable, since you wouldn't go and repair your enemy's stuff...
I'm also in a project, Heal Shield SW. This SW will completely heal only ur con-yard for 30 sec (that means its not a force shield, but it'll heal ur con-yard in every sec within 30 sec). I think u'll like it. But i have problems to implement it for every sides. Hope i can fix that problem
