how do i fix this error

i get this error,

Assets/custom/CUSTOM/Scripts/randomspawnn.js(7,48): BCE0023: No appropriate version of ‘UnityEngine.Object.Instantiate’ for the argument list ‘(int, UnityEngine.Vector3, UnityEngine.Quaternion)’ was found.

from this script,

var items : GameObject [];
var thePrefab = Random.Range(1,items.length);

	function OnTriggerEnter() {
    collider.enabled = false;
	
	var instance : GameObject = Instantiate(thePrefab, transform.position, transform.rotation);

    //------------//

}

how do i fix this?

This is referring to the parameters that you are putting into Instantiate. It’s saying that there are no versions of this function that take an int, a Vector3, and a Quaternion, in that order.

If you look at the documentation for Instantiate, you’ll that the function has only one version: one that takes a an Object, a Vector3, and a Quaternion. If you look at your code, the variable thePrefab is in fact an int type. This explains why you are getting this error. it is asking for an Object, and you are giving it an int instead.

Your real problem is that you are misusing Random.Range. According to the documentation, it returns a random number between the two numbers you gave it.

Assuming what you meant to do was use Random.Range to get the index, you should use the result of Random.Range to get the item you want from items, using the [] operator:

var items : GameObject [];
var index : int = Random.Range(1,items.length);
var thePrefab : GameObject = items[index];
