hello everyone, im tryin to make a script to attach on a gameobject that will find my player via tag and enable/disable the third person controller script on key press, i went on to do this by using nested ifs and it works but when i press the buttons i get null reference please help me!:
var scriptname : ThirdPersonController;
var Player : GameObject;
function Start () {
scriptname.enabled = false;
}
function OnTriggerStay (other : Collider)
{
if(other.gameObject.tag == "Player"){
if(Input.GetKeyDown("2")) {
scriptname.GetComponent(ThirdPersonController).enabled = true;
}
}
else if(Input.GetKeyDown("3")) {
scriptname.GetComponent(ThirdPersonController).enabled = false;
}
}
What is your scriptname variable set to? Do you even need that? Seems like scriptname should either be a string, set to the name of the script component you want to find and call it like this:
GetComponent(scriptname).enabled = true;
or just remove scriptname altogether if you’re always looking for the ThirdPersonController component.
change line 13 and 18 - I am sure you meant Player.GetComponent… etc.
even though it is more economical to store the access to the script in a variable… - but you clearly do not understand the concept of storing something in a variable yet
Make sure you understand what an object is …and what a component is and how you would access component X on GameObject Y .
That is very important (and very basic stuff) .
like Dave mentioned - you did not set your (poorly named) variable scriptname to anything. (and if you didn’t do drag and drop … you also didn’t set your player to anything).
