Hello team aternos. I didn't find a mod called BlockPhysics in your place. I want you to add it. Small description:
This mod enables you to set the blocks of Minecraft to fall. The falling blocks collide with each other and the mobs, causing damage and bouncing off. You can set the mass, strength, moving behavior and a few more properties to customize the worlds physics. Please add.
