Mob Collision Off

by Gvoper

Mob Collision Off turns off collisions between entities, so mobs and other entities no longer push against each other on a server.

FabricForgeNeoForgeClient and serverAll rights reserved1.20.1 – 26.3

What it does

The mod skips the calculation of entity-to-entity collisions. The author states that this steadies TPS and may slightly raise FPS. The mod is published for Fabric, Forge and NeoForge across 22 release versions, 1.20.1 – 26.3, and it is not open source, released under All rights reserved. Mob Collision Off runs on client and server, so both the server and every player need it.

Key features

  1. Entity collision disabled

    Entities no longer collide with each other, so the server skips that calculation for every tick.

  2. Steadier TPS

    According to the author, skipping entity collisions gives more stable server ticks per second.

  3. Possible FPS gain

    The author notes that the frame rate may rise slightly, since the collision work is not done.

What the author says

This will improve TPS stability and may slightly increase FPS because it doesn't calculate entity collisions. Это повысит стабильность TPS и может чуть увеличить FPS, потому что не рассчитывает столкновение сущностей.
