PlayerAnimator (Unofficial 1.21.10 Port)
by antostcr
PlayerAnimator is an unofficial Fabric port of the animation library for Minecraft 1.21.10, letting other mods animate the player model.
What it does
The library animates the whole player model through position, rotation, scale and bend transformations. Body parts such as the head, body, chest, torso, both arms and both legs can each be driven by an animation, and animations can be layered with a priority system so that several run at once without overriding each other.
Animations are read from JSON files in the formats used by GeckoLib and Emotecraft, placed under assets/modid/playeranimator. Other mods that use PlayerAnimator can enable their animations once this library is installed, and the port keeps an API compatible with the original PlayerAnimator project.
Installation needs Fabric API. PlayerAnimator runs on client and server, so both the server and every player need it. Its only published file is for 1.21.10, released under the MIT License, and the code is not open source.
Key features
Full player model animation
Position, rotation, scale and bend transformations can be applied to the head, body, chest, torso and each limb.
Layered animation priority
Animation layers with a priority system let several animations run together, with the higher-priority layer taking precedence.
JSON animation files
Animations load from JSON in GeckoLib and Emotecraft formats, so existing animation assets can be reused.
First-person mode
A first-person animation mode lets animations show in the view the player sees, not only on the third-person model.

Use cases
Mod animation support
Developers of mods that add emotes, combat moves or custom poses can rely on this library instead of writing their own player animation code.
Who it’s for: Mod developers and modpack makers who want animated player poses in 1.21.10 should use this library. Players gain animations only from other mods that depend on it.
How it compares
TweakHands is a Fabric client-side only mod for 1.21.11 under the MIT License, so it does not cover the same library role. Sophisticated Core (Unofficial Fabric port) is a client and server Fabric library for 1.19.2 – 1.21.1 under the GNU Lesser General Public License v3.0 only, and it is open source, unlike this port.
