Array index is out of range (C#) ?
IndexOutOfRangeException: Array index is out of range. Ramdom_Tree.Start () (at Assets/Standard Assets/Scripts/Ramdom_Tree.cs:14)
using UnityEngine; using System.Collections;
public class Ramdom_Tree : MonoBehaviour {
public GameObject[] Cay_Dua = new GameObject[1];
void Start () {
for(var i=0; i< 19; i+=1)
{
transform.position = new Vector3(Random.Range(-200, 200), 0, Random.Range(-200, 200));
Instantiate(Cay_Dua[i], transform.position , transform.rotation); // error
} } }
Instead of hard coding the array length in your loop, try this...
for (var i=0; i < Cay_Dua.length; i+=1)
That said, your array apparently doesn't have the number of items in it that you expect.
You're trying to access elements 0 to 18 from Cay_Dua array, but apparently it contains less elements.
Cay_Dua is defined as a 1-item array in line 2, so it can't work after the first pass. Also, it's defined but never filled, so you're got an empty 1-unit array - calling instantiate will give you a null ref excecption too.
This array is declared as public, so OP probably filled in in inspector. But it seems less than 19 elements was inserted.
