Disable objects that dose not equal Index(array)

Questions & Answers

Hi.

I have a script that disables weapons depending on the Index of an array. Something like so:

var weapons : GameObject[];
var currentWeapon = 0;

function Update () {
	if(Input.GetButtonDown("YButton")){
	currentWeapon += 1;
	if(currentWeapon == 0){
	weapons[currentWeapon].SetActiveRecursively(true);
        weapons[!=currentWeapon].SetActiveRecursively(false); //HERE
    }
	else if(currentWeapon == 1){
	weapons[currentWeapon].SetActiveRecursively(true);
	}
	else if(currentWeapon == 2){
	weapons[currentWeapon].SetActiveRecursively(true);
	}
}
}

But how can I easily set SetActiveRecursively to objects that dose not equal currentWeapon? Some thing like so:

weapons[!=currentWeapon].SetActiveRecursively(false);

Instead of “hard-code” it the above example would be flexible but it gives errors, though.

I hope you get what I mean.

Thank you.

You could use a For loop to set the first item in the loop to true and everything else to false.

if(currentWeapon == 0){		
	for (int i; i < weapons.length; i++) {
		if (i == 0) {
			weapons[currentWeapon].SetActiveRecursively(true);
		} else {
			weapons[!=currentWeapon].SetActiveRecursively(false);
		}
	}
}
else if(currentWeapon == 1)
{
	weapons[currentWeapon].SetActiveRecursively(true);
}
else if(currentWeapon == 2)
{
	weapons[currentWeapon].SetActiveRecursively(true);
}

(Sorry. I don’t know the JS syntax but you should get the general idea.)

var weapons : GameObject;
var currentWeapon = 0;

function Update () {
currentWeapon  = Mathf.Clamp (currentWeapon , 0, weapons.length);
    if(Input.GetButtonDown("YButton")){
    currentWeapon += 1;
    }
selectWeapon(currentWeapon );
}

function selectWeapon(index : int){
for (var i=0;i<transform.childCount;i++){
// Activate the selected weapon
	if (i== index)
		transform.GetChild(i).gameObject.SetActiveRecursively(true);
// Deactivate all other weapons
	else
		transform.GetChild(i).gameObject.SetActiveRecursively(false);
	}
}

Both of the answers would work - my question is which would execute faster? Or is the difference neglible?
