How do I respawn instances of an object?

So saying I have a "Troll" sprite and created few instances of it. Now I need to respawn them every time my player kills them.

But this isn't working. I try to do it with pick by IID. But it only works for one instance. Then I tried creating new spawn sprites for other troll instances and repeat the On Destroyed event but that doesnt work as well. I tried to add another event/sub event pick by unique UID of troll instances but failed.

Im a beginner so I havent got yet to the point to understand UID/IDD very well and if they change on destroy/respawn.

I also tried it without a respawn sprite. And it works ok. But it respawns them instantly, which I dont want it. I added the time behavior to troll but then doesnt respawn at all.

Any help is greatly appreciated.

Thanks in advance.

Im sorry Im afraid I dont understand you. Could you please write a simple example.

Simplify is the spawn object cannot find your Troll.IID after it destroyed

You will need to replace it with your certain layer number.

A simpler method might be to simply turn the troll invisible and disable his movement and logic. He will appear "destroyed" and "respawned" but really you're just hiding and later re-enabling him (allowing him to retain his UID)
