How to make a instance of this, or how to get the instance, because I get an error when trying to use it.
You are trying to create a MonoBehaviour using the 'new' keyword. This is not allowed. MonoBehaviours can only be added using AddComponent(). Alternatively, your script can inherit from ScriptableObject or no base class at all

Hi

You should use Unity’s AddComponent, not new ProceduralGridMover.
