Instantiate as child
I'm trying to make it so that when a collision happens, an object is instantiated at an exact point as the child of another object. How can I do this?
Please add next time more details because your question is very abstract: when "a collision" happens; child "of another" object. And since you didn't post any code you have so far, we only can guess what language you use / want use.
I guess you use JS (because most beginners use JS ;) but i prefer C#)
One way would be something like:
var yourPrefab : Transform; var anotherObject : Transform;
function OnCollisionEnter (collision : Collision){ var anObject : Transform; anObject = Instantiate(yourPrefab, Vector3.zero, Quaternion.identity); anObject.parent = anotherObject; anObject.localRotation = Quaternion.identity; // rotates the object like the parent anObject.localPosition = Vector3(XX,YY,ZZ); // define here your "exact point" within the parent }
You have to give more information whether you want a exact local or global position and if one of your "objects" is involved in the collision?
You instantiate first, then you parent. You can always set position, and after the parenting, set localPosition if you want, instead.
in c# it had to be done like this. Adding this info for anyone else searching for this solution.
GameObject player;
GameObject playerClone;
void Start () {
player = Resources.Load("Player") as GameObject;
Instantiate(player);
playerClone = GameObject.Find("Player(Clone)");
playerClone.transform.parent = GameObject.Find("Main Camera").transform;
}
You should avoid using GameObject.Find() where possible as it will be relatively slow. In this case you can simply cast the newly created player object:
GameObject player;
GameObject playerClone;
void Start () {
player = Resources.Load("Player") as GameObject;
playerClone = Instantiate(player) as GameObject;
playerClone.transform.parent = GameObject.Find("$$anonymous$$ain Camera").transform;
}
Note that if you only want to parent to the current game object (which the script is attached to) you can just use playerClone.transform.parent = transform. Which will save you another GameObject.Find()
