As we all know, when a skeleton kills a creeper it drops an music disk, and if you didn't know you can pick up an mob during its dying animation using a safari net and auto spawn exact copies of it which will instantly die. When you make a skeleton kill a creeper, and you can catch it before it dies, can you put it through the autospawner and autospawn creepers that will drop music disks?
No the record would not drop. The arrow does not maintain the shooter as a nbt tag and the creeper does not maintain the killer as a NBT tag either.
When capturing a mob in a safari net, it saves all of the NBT information of the creature, and because the creeper does not store the DamageSource in a NBT tag, this information is lost upon capturing a creature.
