Json Entity Animation

Json Entity Animation

Json Entity Animation (JsonEA) for short is a library mod for other mods to be able to define animations through JSON instead of through code. A Blockbench plugin (also available in the Blockbench plugins browser) is also provided in order to export your animations to this format.

For developers

Add the mod as a dependency using the Modrinth Maven.

dependencies {
    include(modImplementation("maven.modrinth:json-entity-animation:0.2.1+1.19.4"))
}

Once added, put your animation JSONs in the assets/modid/jsonea directory. To load the animations, your entity model must subclass SinglePartEntityModel/HierarchicalModel. Then define a JsonAnimator field and animation IDs.

public class MyEntityModel extends SinglePartEntityModel<MyEntity> {
    private static final Identifier PUNCH_ANIMATION = new Identifier("modid", "my_entity/punch");
    
    private final JsonAnimator animator = new JsonAnimator(this);
    
    // ...
    
    @Override
    public void setAngles(MyEntity entity, float limbAngle, float limbDistance, float animationProgress, float headYaw, float headPitch) {
        getPart().traverse().forEach(ModelPart::resetTransform);
        animator.animate(entity.punchState, PUNCH_ANIMATION, animationProgress);
    }
}
