No… he creates an entity every time. I’m just saying to reset the decay component to a bit more into the future.
No… have a decay that lasts however long you want the damage to keep going after the step out of the AOE. Most damage might continue damaging for at least a few frames (especially fire)… and it nicely covers the case where they jump out and into the AOE really quickly.
Yes… if you only want damage to instantly stop then set the decay very small. But large enough that it survives for just one frame. (Though even if not then it will get recreated and it’s just a tad wasteful is all.)
