Preserved Topic: Good old setTimeout (Page 1 of 1)

Y'ello

I've always had and still have problems with setTimeout
(EDIT) or maybe I should use setInterval ? (EDIT)

What I'm trying to do is this:

When someone holds down a key, a gif-animation is suppose to move to the left in 8 pixel steps
The problem is that I dont want this to happen to fast, and there should be like a 200millisecond pause between the little moves. So, while holding down it should move, and as soon as the key is released the movement should stop. And the animation changes into a still image. The change between the images I have no problems with.

I've tried several methods and it always goes down to the problem that it moves in the 8 pixel steps too fast.

Hope you understand my problem and I would be grateful for replys,
Thanks in advance,

Bye

How is onkeypress different from onkeydown ?

I get somewhat what you were saying in your first reply but I think I forgot to explain something...
I'm going to move in bigger steps, basically this means that always when moving the object it should always move 16 pixels, BUT in 8 pixel steps. It should finish moving the 16 pxs even if the key is released. Does this make things much more complicated or....

Ok, I basically solved it:

var wTimer;
var frame = 0;
var KEYISDOWN = false;

function keyDown() {
KEYISDOWN = true;
image.src = 'dudeleftwalking.gif';
walkLeft();
wTimer = window.setInterval(checkMove(), 200);
}

function checkMove() {
return walkLeft;
}

function keyUp() {
KEYISDOWN = false;
clearInterval(wTimer);
image.src = 'dudeleft.gif';
}

function walkLeft() {
if (frame < 2) {
image.style.pixelLeft -= 8;
frame++;
setTimeout("walkLeft()",100);
}
else { frame = 0; }
}

document.onkeydown=new Function("if(!KEYISDOWN){keyDown();}");
document.onkeyup=keyUp;


Was this something like what you thought about?
Anyway, thanks a lot for your replys, appreciate it.

Indeed.
