Question by Jason Hamilton · Dec 28, 2010 at 12:01 PM · transformnullreferenceexceptionchildfind

transform.Find(string)?

hey, can i use a string variable (whichGemIGot) that is equal to a gameObjects name (Gem - Blue) ??? what i have now gets NullReferenceException

I know this is probably wrong i just cut out the bits that seemed needed to understand my situation. :P

var whichGemIGot : String; function Update () { if(Input.GetButtonDown("Jump") && isShooter) { var child = transform.Find(whichGemIGot); child.rigidbody.AddRelativeForce(0,-1000,0); transform.DetachChildren(); isShooter = false; } }

function CreateGem () { var whichGem = Random.Range(1,7); switch(whichGem) { case 1: var Gem11 = Instantiate(Gem1, transform.position, transform.rotation); Gem11.parent = transform; whichGemIGot = "Gem - Blue";

Remember that instantiated objects have (Clone) on the end of their name by default

It'll my bet is you need to search for "Gem - Blue (Clone)" instead

Yes you can. If no child with that name exists the function will return null.

Is it a child of the object that your script is attached to? Is it a direct child?

the script is applied to the parent, the child is a direct child
