Prefab Can't be Controlled if Instantiated

Problem has been solved.

 

Hi, you could leave your original post and reply with a solution for others, thanks

edit, you control instantiated objects like this for example:

public GameObject worldObject;
GameObject worldObjectInstantiate;

worldObjectInstantiate = Instantiate(worldObject, transform.position, Quaternion.identity);
worldObjectInstantiate.transform.parent = this.transform;
worldObjectInstantiate.transform.localRotation = Quaternion.Euler(-90, 0, 90);
