⬇ Download on CurseForgeThe author built this one for Minecraft 1.20.1 on Fabric. On other versions it may install and then do nothing.
Overview
Ever get tired of mobs sneaking up on you whilst you're minding your own buisiness? Don't want to stop mobs spawning altogether? Introducing the Automated Defence mod, a simple solution for a simple problem.
- Consumes arrows (including spectral)
- Uses bows and crossbows
- Optional enchanted book slot for easy upgrades
Crafting

The recipe uses vanilla items, making it easy to integrate into any modpack. Use a Dispenser, an Armor Stand, and a Grindstone in a crafting grid as shown above.
Usage

Right-clicking a placed Auto-Turret opens the GUI. From here you can load the turret with a bow/crossbow and arrows, which will activate it. You can also provide an Enchanted book to apply Power, Punch, Flames, or Infinity to any bow in the turret. Enchantments stack, and will apply the highest of each from either the bow or the book.
The turret consumes the durability of the provided bow. Arrows and Tipped Arrows fired by the turret cannot be picked up outside of Creative Mode. Spectral Arrows can be picked up.
The turret picks a random mob in a 16x16 cube around it and shoots directly at that mob until it is further than 16 blocks away or is dead. Auto-Turrets fire at a rate of roughly 2 shots per second (10 ticks per shot).
Mod Support
The bow slot accepts any item that has the c:bows tag. By default this includes vanilla bows and crossbows.
The turret will target any mob that inherits the MobEntity class. In vanilla, this means it will target undead mobs, but not Slimes.
Please use this in your modpacks if you want to.
