Bone Updaters

Bone Updaters are the interface that GeckoLib provides to add bone manipulations to GeoRenderers from outside the renderer itself.

Overview​

Because of the changes Mojang has made to rendering in Minecraft (see: Bone Snapshots), GeckoLib no longer allows bones to be manipulated directly for animation.
Additionally, GeckoLib requires that bone manipulations be done at a specific time in the rendering process.

Due to this, GeckoLib only allows manipulation of bones via BoneUpdaters - an interface that RenderPassInfo provides.

Usage​

If you want to modify bones for a render pass, you have two options:

  1. If you are modifying them inside a GeoRenderer, you override and use adjustModelBonesForRender. See here
  2. If you are modifying them anywhere else, you add a BoneUpdater to the RenderPassInfo
renderPassInfo.addBoneUpdater((renderPassInfo, boneSnapshots) -> {
    // Modify bones here
});

See the BoneSnapshots page for more information on using them.

warning

BoneUpdaters can only be added prior to the render pass being submitted in GeoRenderer#submitRenderTasks. Attempting to add one too late will result in an error.
