Sadly i cant find a way to set the initial value through a global/local variable. If you know any way to do it, please tell. (When i use on to set it every spawn, it resets all active instances to that value, meaning that the first spawn/instance was damaged and would be healed/reset his hp)
For now i use pick #th instance, to set the hp. (Every spawn would +1 to variable that the #th function would use). It's not very nice/clean/neat that way
Update:
The #th doesnt work correctly, trying to set 5th instance while 1creep died (setting all others instance number 1lower xD ), trying to workout a way for that.
Update2:
For some strange reason it suddenly works.... Just setting the value to a certain hp... the reason why? no idea xD
New link for updated project for the interested:
