I've had this trigger work before, but I've modified it so it has more restrictions on who it will choose and it doesn't seem to work anymore. I also transferred it to a new map. It doesn't seem to want to choose any unit at all.
What the trigger is supposed to do, at least the first half of it, is choose the hero with the lowest health on your team. Can someone help me figure out the reason why it doesn't seem to pick any unit?

It heals the unit by 150 per 0.4 seconds 90% of the time?

The problem is ...

((Picked player) controller) Equal to User

... what picked player?

 

[Kelv]

I switched it to 90% just for testing because it didn't want to have to deal with the low percentage. Also, shouldn't the wait .5 plus .1 plus .4 equal a whole second?

Thanks for the help anyways, that was one of the new conditions that I added recently, I guess I'll have to change it to (Owner of Picked Player is equal to user)

I have an additional question if you don't mind answering, can I classify a hero, as a unit? just so it doesn't pass the, triggering unit is a hero conditions, and yet still have all the functions of a hero?

No.
A Hero is a Hero and a Normal unit is a Normal unit.
Be one of them or none at all.
