Is it possible through some use of spawn conditions to make a mob spawn after a specific structure has been built, irrespective of who built it? For example, so far I've only been able to make players be able to spawn custom mobs via placing certain blocks in certain locations.
For example, onblock gold_block combined with inblock diamond_block and heightabove 200 will make a mob spawn inside the diamond blocks, then I can just use the mob to delete the blocks that were used to spawn it...
