A question from a user required them to change the atlas at runtime to add an offset.
The Spine component has a
atlasAsset property that can be given an assetId and will rebuild the spine object to use the new atlas.
this.entity.spine.atlasAsset = this.newAtlasAsset.id; this.entity.spine.state.setAnimation(0, "portal", true);
atlasData that can be used if a JSON object is being created and dynamically changed at runtime.
