Access component from another script

Question

Im using unity and I have Im trying to access a script called Outline on my parent object. I need to disable and enable the script Outline from another

Answer 1

If its on your parent object then:

myScript = gameObject.transform.parent.gameObject.GetComponent<Outline>();

Other good Solution(cos performance is not critical here) by Hugo:

myScript = gameObject.GetComponentInParent<Outline()>;

Not in unity enviroment but i think in the second case gameObject is redundant.

Answer 2

If they are on the same object than

myScript = GetComponent<Outline>();

should already give you the reference you want.

Otherwise if you say it is on the parent object than you should instead use

myScript = transform.parent.GetComponent<Outline>();

or GetComponentInParent (only if the component is enabled and the GameObject active on Start)

myScript = GetComponentInParent<Outline>();

Even better (if possible) would be you make it a [SerializeField]

[SerializeField] private Outline myScript;

and directly reference it via the Inspector than you don't have to use GetComponent at all. Drag&Drop the according GameObject in the field it automatically gets the according component reference.

In order to then enable or disable it simply set MonoBehaviour.enabled

myScript.enabled = true; // or false
