HI Im trying make one spawner with 20 mobs and second with treasure chest, now i have triggedonprop like this GET spawner1,killcount>5 , no Treasure chest is spawned when i kill 5 or more mobs but problem is how to reset all that because killcount stay all the time higher than 5 so the treasure chest is spawned permanently Thanx for answer I hope u Understand what i need ;

The spawner with the treasure chest, the next line after your chest put this:

SET/killcount/0

Make sure on the properties for treasure chest spawner you have the monster spawner set as your setitem. Also, make sure you have the two spawn entries under the same sequence so they spawn at the same time.
