Thanks for the great tutorials, I have found a slight problem with your finished game. I am not sure if your aware that, you can just position your avatar off the screen and none of the enemies can attack you.

Cheers Chris!

Yep, it’s true. I didn’t notice that at first, but I left it in because I think it’s a good challenge to work out how to fix it yourself 🙂

The high score is stored on your own computer, so no one else’s scores will show up.

HI, pretty good game but how can I make it to move on diagonal? D:

Cazbot Commander September 5, 2011 at 8:00 pm

To make it move diagonal you have to make left,right,up, and down boolean fucntions.

Here is some pseudo code for an Idea:
var left:Boolean = false;
var right:Boolean = false;
var up:Boolean = false;
var down:Boolean = false;
var speed:Number = 5;

player.addEventListener(KeyboardEvent.KEY_DOWN, keyTrue);
player.addEventListener(KeyboardEvent.KEY_UP, keyFalse);
stage.addEventListener(Event.ENTER_FRAME, boolListen);

function keyTrue(event:KeyboardEvent)
if(charCode == 37) //or keyCode I forget which one works the best
left = true;
//do this for all charCodes 37 – 40 left-37 up-38 right-39 down-40
//Play around with else if’s and if’s to play around with the logic so you can understand it better

function keyFalse(event:KeyboardEvent)
if(charCode == 37)
left = false;
//again for all of them.

function boolListen(event:Event)
if(left == true)
player.x += speed
//for all charCodes.
// this one I believe should ALL be if’s, no else if’s or else only one at a time will work.
