Add-Ons give you the ability to change the way things in your game look and behave. Using Add-Ons, you can change the rules, appearances and mechanics of things in the game. At a basic level, you can change the way mobs look. But you can also change the way they behave. For example, you can change a chicken to behave like a creeper – to attack and explode. Add-Ons can help you bring new gameplay ideas to life. They are the first step on our journey towards a fully customizable Minecraft.
