Subject: [PATCH] Add '/paper mobcaps' and '/paper playermobcaps'
|
|
|
|
Add commands to get the mobcaps for a world, as well as the mobcaps for
|
|
each player when per-player mob spawning is enabled.
|
|
|
|
Also has a hover text on each mob category listing what entity types are
|
|
in said category
