Questions & Answers

Hello,
I have four missiles on a launcher,
Each press on the fire button toggles another missile
Everything works, except error line 16, Array index is out of range.

var missile :GameObject[];  
var CurrentMissile : int ;


function Start()
{
  CurrentMissile  = 0;
}

function Update () 
{
    if (Input.GetButtonDown("Fire3")) 
	{
	   missile[CurrentMissile].GetComponentInChildren(Homing).Fire();
	   CurrentMissile ++;   
	}     	
}
2

When Currentmissile gets to 3, reset it to 0

3

This means that the variable CurrentMissile is a number that is outside the range of the array.

Does the array have anything in it? I dont see them assigned in the code so have you assigned them in the editor? Right now I see an empty, unititlised array and you are trying to access the first element in it.

Remember an array is a list of a fixed size.

Also this is a common programming question, and in no way specific to Unity so you can find a ton of info on this on the internet. Is this your first time programming?
