I’m working on a platform game and I wan the main character to shoot, I’m very new to Flash and ActionScript; this is ActionScript 3.0. I’ getting:“1026: Constructor functions must be instance methods.” when try to test my game, I don’t know if I have to import a class or what the problem is. The “blasts” are scripted using code from an example I also realize that the blasts are currently coded to shoot vertically I just wanted to able to get this character to shoot. Any help with this is greatly appreciated; below is the code: (I can post the fla. file if that would help)

stage.focus=stage;  
matazon.gotoAndStop(“stand”);  
var shootBlast:Boolean=false;  
var blastArray:Array=new Array(blast0,blast1,blast2,blast3,blast4,blast5);  
var blastIndex:int=-1;  
var moveRight:Boolean=false;  
var moveLeft:Boolean=false;  
var gravity:Number=2;  
var velocity:Number=1.1;  
var jumpPower:Number=0;  
var isJumping:Boolean=false;  
var ground:Number=630-matazon.height;  
var droneDirection:Number=5;  
var matazonScale:Number=matazon.scaleX;  
import flash.ui.Keyboard;  
stop();

stage.addEventListener(Event.ENTER\_FRAME, blastAnimation);  
stage.addEventListener(Event.ENTER\_FRAME, runAnimation);  
stage.addEventListener(Event.ENTER\_FRAME, leftWall);  
stage.addEventListener(Event.ENTER\_FRAME, rightWall);  
stage.addEventListener(KeyboardEvent.KEY\_DOWN, jump);  
stage.addEventListener(Event.ENTER\_FRAME, nojump);  
stage.addEventListener(KeyboardEvent.KEY\_DOWN, downKey);  
stage.addEventListener(KeyboardEvent.KEY\_UP, upKey);  
stage.addEventListener(Event.ENTER\_FRAME, moveOver);  
stage.addEventListener(Event.ENTER\_FRAME, matazonFunction);  
stage.addEventListener(Event.ENTER\_FRAME, droneLeft);  
stage.addEventListener(Event.ENTER\_FRAME,checkCollision);

function checkCollision(event:Event) {  
if (matazon.hitTestObject(drone)) {

```
    stage.removeEventListener(Event.ENTER_FRAME, blastAnimation);
