What this error means ..?

[anon_24863542]

in this script:

// created by Dastardly Banana Productions
// http://www.dastardlybanana.com/

//This is a dummy script to fool the radar, since our AI script is not ready to be posted at this time.
// “isChasing” is true

var isChasing : boolean;
var seeDistance : float = 50;

function Start () {
}
function Update () {
var gos : GameObject[ ];
gos = GameObject.FindGameObjectsWithTag(“Player”);
//assumes only one player
var thePlayer:GameObject = gos[0];
var dist = Vector3.Distance(thePlayer.transform.position,transform.position);

if(dist<seeDistance){
isChasing= true;
} else {
isChasing=false;
}
}

the console gave me this error:

IndexOutOfRangeException: Array index is out of range.
EnemyAI.Update () (at Assets/Radar/EnemyAI.js:16)

the colsole refer to this line -specially-:

var thePlayer:GameObject = gos[0];

what is the error? help, please!

It means there is no gos[0].

GameObject.FindGameObjectsWithTag(“Player”) did not find any GameObjects with the tag “Player”

Exactly what it says - there is no object at the 0 index of that array, or more specifically - your array has no elements because you never gave it a length. The distinction between JavaScript arrays and .NET arrays is an important one: http://unity3d.com/support/documentation/ScriptReference/Array.html

This error means this line GameObject.FindGameObjectsWithTag("Player"); didn’t find any gameobject with the tag Player, so the array returned was empty

A simple…

if(gos.Length==0) return;

would fix this.

Or just use GameObject.FindGameObjectWithTag(“Player”); To not get a array at all. ( no s )
