I need help with shooting in my flash game for University

Question

Hi there
Ive tried to make my tank in my game shoot, all the code that is there works but when i push space to shoot which is my shooting key it does not shoot I really need help with this and I would appriciate anyone that could help
listed below should be the correct code
//checking if the space bar is pressed and shooting is allowed
if(evt.keyCode == 32 && shootAllow){
    //making it so the user can't shoot for a bit
    shootAllow = false;
    //declaring a variable to be a new Bullet
    var newBullet:Bullet = new Bullet();
    //changing the bullet's coordinates
    newBullet.y = tank_mc.y + tank_mc.width/2 - newBullet.width/2;
    newBullet.x = tank_mc.x;
    //then we add the bullet to stage
    addChild(newBullet);
listed below is my entire code
import flash.display.MovieClip;
    //declare varibles to create mines
//how much time before allowed to shoot again
var cTime:int = 0;
//the time it has to reach in order to be allowed to shoot (in frames)
var cLimit:int = 12;
//whether or not the user is allowed to shoot
var shootAllow:Boolean = true;

var currentHP:int = maxHP;
var percentHP:Number = currentHP / maxHP;

    minesInGame = 15;
    //create a timer fires every second
    mineMaker = new Timer(6000, minesInGame);
    //tell timer to listen for Timer event
    mineMaker.addEventListener(TimerEvent.TIMER, createMine);
    //start the timer
    mineMaker.start();

//create a new instance of tankMine

Answer 1

USe the trace function to analyze what happens and what fails to happen in the code you showed.  trace the conditional values to see if they are set up to allow a shot when you press the key
