@ -260,6 +260,8 @@ functions needed for the mob to work properly which contains the following:
'pick_up' table of itemstrings the mob will pick up (e.g. for breeding)
'on_pick_up' function that will be called on item pickup - return true to not pickup the item
'custom_visual_size' will not reset visual_size from the base class on reload
'noyaw' If true this mob will not automatically change yaw
'particlespawners' Table of particlespawners attached to the mob. This is implemented in a coord safe manner i.e. spawners are only sent to players within the player_transfer_distance (and automatically removed). This enables infinitely lived particlespawners.
