addEventListener() isn't detecting KEY_UP nor KEY_DOWN
- by Zirenth
My full code is
import flash.events.KeyboardEvent;
import flash.events.Event;
//init some variables
var speedX = 0;
var speedY = 0;
msg.visible = false;
var curLevel = 2;
var level = new Array();
var flagVar;
var won = false;
//Adding level platforms
for(var i = 0; i < numChildren; i++) {
if(getChildAt(i) is platform) {
level.push(getChildAt(i).getRect(this));
}
if(getChildAt(i) is flag) { flagVar = getChildAt(i).getRect(this); }
}
//Checking key presses
var kUp = false;
var kDown = false;
var kLeft = false;
var kRight = false;
var kSpace = false;
stage.addEventListener(KeyboardEvent.KEY_DOWN, kD);
stage.addEventListener(KeyboardEvent.KEY_UP, kU);
function kD(k:KeyboardEvent) {
trace("Key down - " + k.keyCode);
if(k.keyCode == 32) { kSpace = true; }
if(k.keyCode == 37 ) { kLeft = true; }
if(k.keyCode == 38) { kUp = true; }
if(k.keyCode == 39) { kRight = true; }
}
function kU(k:KeyboardEvent) {
trace("Key up - " + k.keyCode);
if(k.keyCode == 32) { kSpace = false; }
if(k.keyCode == 37) { kLeft = false; }
if(k.keyCode == 38) { kUp = false; }
if(k.keyCode == 39) { kRight = false; }
}
addEventListener(Event.ENTER_FRAME, loopAround);
function loopAround(e:Event) {
//horizontal movement
if(kLeft) {
speedX = -10;
} else if(kRight) {
speedX = 10;
} else {
speedX *= 0.5;
}
player.x += speedX;
//horizontal collision checks
for(var i = 0; i < level.length; i++) {
if(player.getRect(this).intersects(level[i])) {
if(speedX > 0) {
player.x = level[i].left - player.width;
}
if(speedX < 0) {
player.x = level[i].right;
}
speedX = 0;
}
}
//vertical movement
speedY += 1;
player.y += speedY;
var jumpable = false;
//Vertical collision
for(i = 0; i < level.length; i++) {
if(player.getRect(this).intersects(level[i])) {
if(speedY > 0) {
player.y = level[i].top - player.height;
speedY = 0;
jumpable = true;
}
if(speedY < 0) {
player.y = level[i].bottom;
speedY *= -0.5;
}
}
}
//JUMP!
if((kUp || kSpace) && jumpable) {
speedY=-20;
}
//Moving camera and other
this.x = -player.x + (stage.stageWidth/2);
this.y = -player.y + (stage.stageHeight/2);
msg.x = player.x - (msg.width/2);
msg.y = player.y - (msg.height/2);
//Checking win
if(player.getRect(this).intersects(flagVar)) {
msg.visible = true;
won = true;
}
//Check for next level request
if(kSpace && won) {
curLevel++;
gotoAndStop(curLevel);
won = false;
}
}
The section in question is
//Checking key presses
var kUp = false;
var kDown = false;
var kLeft = false;
var kRight = false;
var kSpace = false;
stage.addEventListener(KeyboardEvent.KEY_DOWN, kD);
stage.addEventListener(KeyboardEvent.KEY_UP, kU);
function kD(k:KeyboardEvent) {
trace("Key down - " + k.keyCode);
if(k.keyCode == 32) { kSpace = true; }
if(k.keyCode == 37 ) { kLeft = true; }
if(k.keyCode == 38) { kUp = true; }
if(k.keyCode == 39) { kRight = true; }
}
function kU(k:KeyboardEvent) {
trace("Key up - " + k.keyCode);
if(k.keyCode == 32) { kSpace = false; }
if(k.keyCode == 37) { kLeft = false; }
if(k.keyCode == 38) { kUp = false; }
if(k.keyCode == 39) { kRight = false; }
}
This was working fine last night, but today I moved it to a new keyframe and now it's not working. I'm not getting any errors (even if I debug). It just won't move the character or even show up in output.
I'm still quite new to as3, so I don't really know what to do.
Thanks in advance.
Edit: After playing with it a bit, I've found out that the reason it's not working is due to the menu. The menu has a single button and two text elements, which are fine. The code that I'm using on the menu is this:
import flash.events.MouseEvent;
stop();
var format:TextFormat = new TextFormat();
format.size = 26;
format.bold = true;
playGameButton.setStyle("textFormat", format);
stage.addEventListener(MouseEvent.CLICK, playGame);
function playGame(e:MouseEvent) {
if(e.target.name == "playGameButton") {
gotoAndStop(2);
}
}
If I use just gotoAndStop(2); it works fine, but with everything else it just goes to the second frame, and nothing else works after that.
Edit #2: I've narrowed it down even farther to the if statement itself.
if(e.target == playGameButton)
if(e.target.name == "playGameButton")
Both of those don't work. If I just remove the if statement all together it works perfectly fine.
