Как одновременно запустить два метода?

Подскажите пожалуйста, как сделать чтобы два метода выполнялись одновременно, при попытке через thread выбивает UnityException: get_transform can only be called from the main thread. Constructors and field initializers will be executed from the loading thread when loading a scene. Don't use this function in the constructor or field initializers, instead move initialization code to the Awake or Start function.
