Player Animation Core

🎬 Player Animation Core

Keyframe-based animation library for NeoForge — powering custom player animations in Minecraft.

---

✨ Overview

Player Animation Core (PAC) is a library mod for NeoForge that provides a flexible, layered animation system for player models. It powers custom animations for mods like Dinamyc Combat, allowing smooth, keyframe-based animations for combat, movement, and more — with full first-person support.

🎯 Features

🎞️ Keyframe Animation System

Define animations in JSON using GeckoLib-style keyframes. Full control over bone transforms: position, rotation, scale per keyframe with configurable easing.

🧩 Layered Animation Stacking

Multiple animations run simultaneously with priority layering. Higher-priority animations override lower ones per-bone, enabling complex blends like walking + attacking.

👁️ Four First-Person Modes

THIRD_PERSON_MODEL — Full 3D player model rendered in first person with configurable part visibility.
HANDS_ONLY — Item bone transforms applied on top of vanilla first-person hands.
HANDS_ONLY_ARM — Arm bone rotations (configurable scale) applied to vanilla first-person item rendering. Matches third-person arm swing without extra keyframes.
VANILLA — Standard Minecraft first-person view.

⚙️ FirstPersonConfiguration

Control visibility of arms, items, and armor per-animation. Configurable arm rotation scale, arm length, and pitch factor for per-weapon tuning.

🦴 Bone Transform API

Query and apply transforms to any body part: head, torso, arms, legs, right/left item. Automatically mirror animations for left-hand rendering with MirrorIfLeftHandModifier.

📦 Lightweight

Designed as a library — zero visual changes on its own. Only affects rendering when another mod triggers an animation. Perfect dependency for combat, parkour, emote, or any animation mod.

📋 Requirements

Minecraft	26.1.2
NeoForge	26.1.2.78+

🎮 For Mod Developers

Add PAC as a dependency in your build.gradle:

repositories {
    maven {
        url "https://gitlab.com/api/v4/projects/stalking-dragons/minecraft/player-animation-core/packages/maven"
    }
}

dependencies {
    implementation "com.skd:player_animation_core:0.0.0-beta.21"
}

Register an animation factory:

PlayerAnimationFactory.ANIMATION_DATA_FACTORY.registerFactory(
    Identifier.of("yourmod", "combat"), 1000, YourController::new);

Trigger animations:

var layer = PlayerAnimationAccess.getPlayerAnimationLayer(avatar, FACTORY_ID);
if (layer instanceof PlayerAnimationController controller) {
    controller.triggerAnimation(animId);
}

Override first-person config:

@Override
public FirstPersonMode getFirstPersonMode() {
    return FirstPersonMode.HANDS_ONLY_ARM;
}

@Override
public FirstPersonConfiguration getFirstPersonConfiguration() {
    return new FirstPersonConfiguration()
        .setArmRotationScale(1.0f)
        .setShowArmor(true);
}
