My /kill @e isn't killing
I'm trying to destroy dropped Oak Planks, and my command is:
/kill @e[type=item,tag={id:"minecraft:oak_planks"}]
But it doesn't work.
The [tag=] you use in the selector isn't the same with the NBT tag {tag:{}}, you need to use [nbt={}] instead of [tag=] for it to work.
Here's the fixed version:
/kill @e[type=item,nbt={id:"minecraft:oak_planks"}]
