Third Law
Java mod listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.
This mod (jokingly) adds newton's third law to minecraft! When you throw an item or shoot a projectile you get pushed back with (un)realistic force!
⬇ Download on ModrinthThis mod makes it so when you throw items or shoot projectiles, it throws you backwards! Most unstackable items as well as projectiles have custom values, but most other items do not have a non-default value! This should be datapackable, so if you'd like to do that, or add modded blocks/items that have non-default values you can!
This mod adds 3 gamerules to control the knockback, you can enable/disable both item and projectile knockback, as well as whether being in the air is required!
Projectile knockback also affects mobs such as pillagers, blazes, and skeletons!
Let me know if you'd like any features implemented!
