Mean Mobs is a light-weight mod made for modpack creators (or users that know how to mess with configs a little) that allows the customization of targetting behavior for ANY mob, both vanilla and modded.
Ever wanted zombies to attack skeletons on sight? Now you can!
Ever wanted endermen/spiders/wolves attack the player on sight? Yup, you can do that too.
Ever wanted absolute chaos by making creepers hostile towards anything that breathes? No? Well you can do that anyway.
How to use:
1) Install the mod as normal
2) Run the game once for the config to generate
3) Exit the game and go into your config folder. (No Configured support yet, sorry)
4) Locate meanmobs-common.json and edit it.
This config file will automatically include every living entity both from vanilla and modded, and attempt to add it inside of it.
Config settings available (with example)
when opening the config, you'll see something like;
"minecraft:zombie": {
"targets": [],
"overrideVanillaTargets": false,
"exclude": false,
"attackEverything": false,
"attackEverythingExceptions": [],
"attackEverythingIncludingSelf": false
},
If there's a mob from a specific mod missing from this list, you can simply include it by copy pasting one of the other mobs and replacing the mod id and mob name, for example:
"examplemod:example_mob": {
"targets": [],
"overrideVanillaTargets": false,
"exclude": false,
"attackEverything": false,
"attackEverythingExceptions": [],
"attackEverythingIncludingSelf": false
},
What the settings do:
"targets": Array to insert any mob to add to the target list. If exclude is turned off, any mobs in this list will be attacked by the mob. Add "minecraft:player" to include the player in this list.
example: "targets": ["minecraft:skeleton,", "minecraft:player"]
"overrideVanillaTargets": Boolean that removes the mob's vanilla targetting settings (Not functional at the moment)
"exclude": Boolean that turns the "targets" list into a whitelist. Any mob NOT on the "targets" list will be attacked.
"attackEverything": Boolean that makes it so the mob.. uh, you know. Attacks everything.
attackEverything does not include attacking players, you have to add minecraft:player into the targets list if you want to include players being attacked.
"attackEverythingExceptions": Array that excludes the added mobs from being targetted.
example: "attackEverythingExceptions": ["minecraft:creeper", "minecraft:silverfish"]
"attackEverythingIncludingSelf": Boolean that allows mobs of the same type to fight eachother. Very chaotic.
Please leave any bugs/feedback/suggestions in the comments.
