getInstances method

@override Future<List<ThermionEntity>> getInstances(ThermionEntity entity)

Returns all instances of entity.

Implementation

@override
Future<List<ThermionEntity>> getInstances(ThermionEntity entity) async {
  final instanceCount = await getInstanceCount(entity);
  final buf = _module._malloc(instanceCount * 4) as JSNumber;
  _module.ccall(
      "get_instances",
      "void",
      ["void*".toJS, "int".toJS, "int*".toJS].toJS,
      [_sceneManager!, entity.toJS, buf].toJS,
      null);
  final instances = <ThermionEntity>[];
  for (int i = 0; i < instanceCount; i++) {
    final instanceId =
        _module.getValue((buf.toDartInt + (i * 4)).toJS, "i32") as JSNumber;
    instances.add(instanceId.toDartInt);
  }
  _module._free(buf);
  return instances;
}
