CS3/AS2 moving objects

programming flash
1

Heya. It’s been a long time since I used flash and actionscript, and I thought Id try to make something simple to start with, a basic rpg. To start off, im trying to do everything using classes and OOP as much as possible - I want to use as little code in the timeline as possible, and I never put code directly on objects, so everything has to be external.

That said, I have it mostly working (not that there’s much TO be making work…), though for some reason it isnt recognizing coordinate commands. Im sure its probably something ridiculously simple that im simply overlooking, but Id appreciate any input. Thanks all!

Heres the code:

Main Timeline:

import Pawn;

var player_1: Pawn = new Pawn(5); //no space after = sign. the post wanted to make that a smiley face
trace("Pawn 1: " + player_1.showInfo());

External file named Pawn - the lines im having trouble with are the “this._x += walkSpeed;” lines in the if statements. I know the if statement is sloppy, ill clean it up later. right now i just want to make it work and im not worried about “pretty” yet.:

import flash.events.*;

class Pawn {

public var walkSpeed:Number = 0;
public var walkListener:Object = new Object();

//Constructor
public function Pawn(_walkSpeed:Number) {
walkSpeed = _walkSpeed;

    // create the listener event inside the constructor so that when the object
    // is destroyed, the listener goes away with it
    walkListener.onKeyDown = function() {
            if(Key.isDown(Key.RIGHT)) {
                    this._x += walkSpeed;
                    trace ("You Pressed the Right Arrow. X Coord is: " + this._x);
            }
			
            if(Key.isDown(Key.LEFT)) {
                    this._x -= walkSpeed;
                    trace ("You Pressed the left Arrow. X Coord is: " + this._x);
            }
			
            if(Key.isDown(Key.UP)) {
                    this._y -= walkSpeed;
                    trace ("You Pressed the up Arrow. Y Coord is: " + this._y);
            }
			
            if(Key.isDown(Key.DOWN)) {
                    this._y += walkSpeed;
                    trace ("You Pressed the down Arrow. Y Coord is: " + this._y);
           }
    }
    Key.addListener(walkListener);

}

//Temporary for testing
public function showInfo():String {
return ("Speed: " + walkSpeed);
}

}

and that’s it. Like I said, im sure it’s probably something insanely simple, but I just either cant remember what it is or its something I didnt know to begin with.

Thanks again.

Also, it doesnt seem to want to let me format the code :confused: sorry

Edit: Forgot to mention that there is a movieclip on the stage. in the library the movieclip is named player_mc and on the stage, the instance name of the movieclip is player_1. I have the player_mc linked to the Pawn.as and exported for actionscript.
