getChildEntity method
Finds the child entity named childName
associated with the given parent.
Usually, parent
will be the return value from loadGlb/loadGltf and childName
will be the name of a node/mesh.
Implementation
@override
Future<ThermionEntity> getChildEntity(
ThermionEntity parent, String childName) async {
return (await _shim.getChildEntity(parent, childName).toDart).toDartInt;
}
