Making a flight script dependent on several variables activated by another script.

Question

For a magic based game I am making, I need there to be a flight script which lets the player fly by pressing the space bar, but only after pressing the keys O P I. I tried doing it several ways. At this point my code looks like this:

 function FixedUpdate ()
 {
     Debug.Log ("Update Called");
     if (MainScript.flying == true)
     {
         if (Input.GetKey(KeyCode.Space))
         {
             Debug.Log ("Flight Attempted");
             var input = new Vector3 (Input.GetAxis("Horizontal"),0,Input.GetAxis("Vertical"));
             GetComponent.<Rigidbody>().AddForce(input);
             Debug.Log ("Flight Successful");
         }
     }
 }

This does nothing, although all Debug.Logs are being triggered. I do not know if there is any way for this code to work, so it may be necessary to start from scratch. I really don't care anymore so long as it works. Keep in mind that I am relatively new to programming, so try to be specific in your answers as there are a lot of features that I have no clue how to use.

First, make sure the object has a rigidbody. It's pretty obvious, but sometimes, people forget it.

Try saving rigidbody to a variable, so, at the beginning of the program, write,

 public Rigidbody rb;
 //You are using JS, so you may need to save it as a var instead of Rigidbody.
 //Sorry, I don't get how JS variables work

Then, In void Start, write

 function Start() {
      rb = GetComponent<Rigidbody>();
 }

Then, drag your object into where it says Rb in the editor, like so: alt text

Hope it helped! And, Good luck on your game. Sounds like a great idea.

P.S: I don't know that my code will work. I used C# :/

 var rb : Rigidbody;
 
 function Start(){
     rb = GetComponent.<Rigidbody>();
 }

it's not mandatory but it will speed the game up a tad bit.
