I was trying to make minecraft sculptures and art with {NoAI:1} mobs, like sethbling did. When I tried to spawn an EnderDragon with NoAI, he just flew away and did what an enderdragon normally does.
No screenshots needed... 🙂
Oh and I used
/summon EnderDragon ~ ~ ~ {NoAI:1}to spawn him. Seems correct.
EDIT: It doesn't work for LightningBolt too, but maybe that is intended.
And also not for Potions, Items and Arrows...
This issue is a duplicate of MC-65603. It has been linked to the original bugreport.
Please search before reporting any bugs, as it's likely that one exists already.
The lightningbolt is not a living entity and does not have AI.
