"FindObjectsOfType" in specific gameObject only?

Question

Hi all, quick question about "FindObjectsOfType"...right now the way it's being used returns all objects of type T[] in the scene:

public GameObject myGO;

void Awake(){

 foreach(GameObject go in FinObjectsOfType(typeof(GameObject)) as GameObject[])
 {
     if (go.name == "The Name I'm Looking For")
     {
         myGO = go;
     }
 }

Returning all GameObjects in the scene when I'm only looking for only 1 object, which I know is a child of another GameObject, is a huge waste of time. So is there a way to do this:

public GameObject myGO; private GameObject playerObj;

void Awake(){

 playerObj = GameObject.FindWithTag("Player");

 foreach(GameObject go in playerObj.FinObjectsOfType(typeof(GameObject)) as GameObject[])
 {
     if (go.name == "The Name I'm Looking For")
     {
         myGO = go;
     }
 }

That way "FindObjectsOfType" only looks in the "playerObj" GameObject for objects of type "GameObject" instead of looking through the entire scene.

Also, is "FindObjectsOfType" faster the "GameObject.Find" ?

Thx for any help in advance! Stephane

If I'm reading you right, you just want to find a specific gameObject from the children of playerObj. If that's the case, then you could do something like this:

public GameObject myGO; private GameObject playerObj;

void Awake(){

 playerObj = GameObject.FindWithTag("Player");

 childTransforms = playerObj.GetComponentsInChildren&lt;Transform&gt;();
 foreach(Transform currentChildTransform in childTransforms)
 {
     if (currentChildTransform.gameObject.name == "The Name I'm Looking For")
     {
         myGO = currentChildTransform.gameObject.name;
     }
 }

Please note, the above is untested C# and may contain errors.

Yes the "GetComponent" method is the way to go for this! It's a lot faster then looking up every object type in the scene...thanks for your help Elliot!
