Accessing the sibling of an object

Question

Hey guys, this may be entirely too simple of a question but for some reason everything I try isn't working. I'm shooting a raycast at an enemy who has a collider that is a child of the main object. So when I cast the ray, it returns the out hit and I can call GetComponent();

I need to get a script that isn't attached to the collider object, nor the parent, I need to access a sibling of the object I've hit. Is there any way to call GetComponent on a sibling? ![alt text Trying to access MouseLook from the Collider.

That was it!
Script script = temporaryHit.parent.GetComponentInChildren
Thanks!

Downvote. This does not access the child, only a component in the child

Transform transform = temporaryHit.parent.FindChild("Child Name");

OR

Transform transform = temporaryHit.parent.GetChild(0);

GetChild(0) gets first child (1) gets second etc.

You can get the next child of the same parent by using the GetSiblingIndex like this:

 SomeObject.transform.parent.GetChild(SomeObject.transform.GetSiblingIndex() + 1);

That is the easiest way for me:

 someObject = transform.parent.gameObject.transform.GetChild(0).gameObject;

The number in the brackets next to the GetChild() part is the index for the children of the parent object, so in this case, it will access sibling object that is the first child (index number 0), increase index number to access next child in the hierarchy. Hope it helps someone as it took me a while to get it right. Cheerio!

Hey I dont know why I am doing this because I am very late, but instead of doing

 someObject = transform.parent.gameObject.transform.GetChild(0).gameObject;

You can do:

 someObject = transform.parent.GetChild(0).gameObject;

The reason is that transform.parent or transform.GetChild (all types of these methods) return a transform. In your code, you are getting the transform's parent (which will give the transform), then getting the gameObject of the parent and then getting the transform from the gameObject.
