Avoider Game — Part 12

Hi,

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.

thanks

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

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.
}

mine? 100000! oh yeah
