Dynamic Hitboxes
by SSH
Dynamic Hitboxes changes how a player's hitbox is sized while the player is in certain poses, such as elytra flight and swimming.
What it does
Dynamic Hitboxes adjusts the player's collision box to match the pose the player is in, so a flying or swimming player is hit where the body actually sits. The mod shows these hitboxes on screen and reacts to the items a player holds. It runs on the client alone, so servers do not need to install it. Files target Fabric for 1.21.10 and 1.21.11, under a Creative Commons Attribution Non Commercial 4.0 license, and the project is not open source.
Key features
Elytra and swimming hitboxes
The hitbox follows the shape of the player while gliding with an elytra or swimming, rather than staying in the standing box.
Hitbox display
The mod shows the current hitboxes of players, making the collision area visible while fighting.
Item-based changes
The hitbox reacts to the items a player uses, so a flying player holding a mace can be hit in PvP with a different box.
