Adding an existing script to a gameobject programmatically

Question

Is there a way to take a script and apply that specific script to an object through code? In pseudocode, what I'm trying to do is essentially as follows:

ObjectOne.MyScript = ObjectTwo.GetComponent<MyScript>();

The closest thing I've found to doing this is AddComponent(), but that only takes either a string or a type and I'd assume it just finds the relavant script and instantiates a clean copy of it. That could work for what I want to do as I could just fill in the relevant information, but that would be tiresome and there should be an easier way to do this.

Answer 1

Yes, the only way is using AddComponent():

var myScript = gameObject.AddComponent<MyScript>();

I don't see how this can be tiresome. There's no way to instantiate a MonoBehaviour so you cannot have multiple instances of your script instantiated by yourself and added them to the game objects on the go - if that's what you thought.

Update

There's really no way to reparent or move a component, so you'll probably have to copy.

However, there's another approach! Instead of having this component in your main Game Object you could instantiate a child Game Object that would just act as a container for your component, and you would move this child to other Game Objects as necessary. Of course the viability of this idea depends on the complexity of the relationship between the main Game Object and the component: if the component uses too many variables of the main Game Object it may be tiresome to reposition it to a child Game Object.
