Solid Entity Hitboxes
by Stray123
Solid Entity Hitboxes makes the hitboxes of certain mobs solid on a server, so players cannot walk through them.
What it does
The mod is a server-side change that makes the hitboxes of selected entities solid. Players and other entities collide with those mobs instead of passing through them, which affects combat, pathing and movement around the affected creatures. Only the server needs the mod to apply the change, since it sets the collision behaviour for the entities it covers.
The covered entities are the snow golem, the wandering trader, the zombie villager, the zombified piglin and the piglin brute. Players on the server do not need the mod installed to get the effect, but a client may still run it. Builds are published for Fabric, Forge, NeoForge and Quilt, and the three game versions 1.21.6, 1.21.7 and 1.21.8 each have files.
The project is licensed as All rights reserved and is not open source, so redistribution and modification fall under that license. The latest file on every loader is 1.0+mod for 1.21.8, dated 2025-11-28, which is also the first publication date.
Key features
Solid mob hitboxes
Selected entities block players and other mobs from moving through them, so their collision matches a solid object.
Covered entity list
The change applies to the snow golem, wandering trader, zombie villager, zombified piglin and piglin brute.
Server-side behaviour
The collision change is applied on the server, so a server can use it without requiring every player to install anything.

Use cases
Pvp and mob blocking
Server owners who want mobs to act as physical barriers can use the mod to stop players from walking through them.
Village trading
Wandering traders and villagers can block movement around a trading spot, which keeps them from being pushed or bypassed.
Who it’s for: Server owners who want certain villagers, traders and piglins to behave as solid obstacles, and modpack builders who run a server with this collision rule.
How it compares
Solid Entities is the closest match, a Fabric-only mod for 1.21.11 with a Creative Commons non-commercial license that is not open source. Prettier Hitboxes is a client-side mod for Fabric and Quilt across 1.21.1 – 1.21.10 under the MIT License, so it changes what a player sees rather than server collision. PVP hitboxes is client-side only as well, for 1.16.5 – 26.3 on Fabric, Forge and NeoForge, and is not open source.
