Peaceful-ish

This mod introduces 2 new gamerules:

• peacefulMobs: determines if mobs will attack
• OnPeaceful: (default) hostile mobs will be passive if the difficulty is peaceful
• Always: Hostile mobs will always be passive
• Never: Hostile mobs will always be hostile, even in peaceful

• mobsInPeaceful: determines if hostile mobs can exist in peaceful difficulty
• false: (default) vanilla behavior, mobs dont spawn and instantly despawn in peaceful
• true: hostile mobs can spawn and remain in peaceful.

If you want mobs to exist in peaceful but not spawn use the vanilla gamerule doMobSpawning
