NoCollisions
NoCollisions is a datapack that turns off player-to-player collision, so players can walk through one another on a server.
What it does
Minecraft normally stops players from pushing through each other, which can leave them stuck in tight spaces during builds, PvE combat and spawn gatherings. This datapack disables collisions between players, letting them move freely through one another. Its effect is on player movement only and does not change terrain or mob collision.
The datapack is aimed at multiplayer servers, minigames, roleplay worlds and any setting where movement freedom matters. Server owners and single-player players can install it by dropping the datapack into a world's datapacks folder and reloading the world. It works alongside other datapacks and vanilla gameplay.
Installation needs no extra mods or setup. The server requires NoCollisions, and clients may leave it out. It is published as a data pack for the 1.21.2 – 1.21.4 range, with the latest build for 1.21.4, and is not open source; the mod is All rights reserved by Kittiese Studios.
Key features
Player collision removed
Players can pass through each other, so being pushed into corners or stuck in narrow passages no longer happens.
Lightweight datapack
The change is delivered as a single datapack with no mod loader needed, adding little overhead to the world.
Simple installation
The file goes into the world's datapacks folder, and a reload applies it without further configuration.
Vanilla-compatible
The datapack leaves other datapacks and vanilla gameplay in place, changing only the collision rule between players.

Use cases
Crowded PvE and spawn areas
Groups gathering at a spawn point or fighting together can move past each other without bumping.
Builds and roleplay
Players working in the same space or moving through crowded scenes keep their movement free.
Who it’s for: Server owners running multiplayer, minigame or roleplay worlds, and players who want to move through others during shared builds or events.
How it compares
Random Player Size is needed on the server, with the client optional only when the server runs it, so players can join without it; it is released under the GNU Lesser General Public License v3.0 only, is not open source, and has files for 1.21.2 – 26.2. Collision Damage Port is open source under the MIT License and is for client and server together, covering 1.20.1 – 1.21.11 on Fabric, Forge and NeoForge, so it changes the collision rule on both sides instead.
