Control Mob Spawns

Control Mob Spawns 1.1.0 adds groups, editing several mobs at once and a key to open the world configuration, and fixes spawn rules for monsters.

New

• Groups: give settings to a named group that mixes mobs, entity tags (#minecraft:undead) and categories (@monster…), minus the mobs or tags you exclude. Groups are ordered by priority; the mob's own settings always win, and list settings (banned biomes, spawn types, NBT bans) are merged
• Several mobs at once: in the Mobs tab, Select… lets you edit several mobs together, paste copied settings on them, or make a group of them
• Copy / paste settings between mobs and groups
• Inherited values: a mob's settings screen shows the values its groups give it, with the group's name. A mob can ignore its groups to keep only its own settings
• Key to open this world's configuration while playing (unbound by default, in Controls → Key Binds → Control Mob Spawns)
• ↺ reset buttons on every changed value
• Group NBT editors suggest the paths of all their mobs, and list which mobs have each path

Fixes and changes

• Spawn rules now really replace the mob's own conditions: a rule allowing daylight spawns zombies in daylight (natural spawning, chunk generation and spawners)
• New spawn rules start with light 0–15 and the full build height, so they exclude nothing
• NBT proportions skip mobs that don't have the path
• The Current mobs tab now comes right after Mobs

Requirements

• Minecraft 26.2
• Fabric Loader 0.20.1 or newer
• Fabric API
• Java 25
• Mod Menu, optional: adds the button that opens the menu
