I want to make a plugin that loops the blocks around a player and has a very small chance of them becoming spawners. I am having 2 issues one whenever I do this it uses the default spawners which is pig and I was wondering how to make that something else and I want it to only loop blocks that are not already spawners.

Skript Version: 2.5.3

Code:
command /spawner:
trigger:
loop all blocks in radius 50 around players:
if loop block is not spawner:
chance of 0.0051%:
set loop-block to zombie spawner

Errors: It says that it can't compare loop block with an item type and zombie spawner doesn't work saying that it is also an item type

 

Thanks for the help but this still does not work it says that spawner with nbt ¨{SpawnData:{id:"minecraft:zombie"}}¨ is neither an item type or a block data. Any idea on how to fix this?

 

That's okay. Thanks for trying to help!
