This data pack adds 3 turrets. To acquire them, enter the command "/trigger give_turret". For the turrets to be functional they need to be within 10 blocks of an active relay, which is activated with a redstone signal, and deactivated by removing the signal. Additionally, at least on generator must be present in the world, anywhere as long as it is loaded.
If these conditions are met, the turrets will attack nearby hostile mobs.
