double press?

[kpxnamja]

I've come to a stumbling point.
How do you have flash recognize a double pressed key from a single press?
Similar to a double click on a window program opening the software, and a single click selecting the program. How would you program flash to do a similar detection?

For instance, if I have a MC named "hero" and I want it to move casually with these simple movement scripts:


_root.hero.onEnterFrame = function() {
if (Key.isDown(87)){
movement = "up";
this._y -= _root.speed;
}
if (Key.isDown(83)){
movement = "down";
this._y += _root.speed;
}
if (Key.isDown(65)){
movement = "left";
this._x -= _root.speed;
}
if (Key.isDown(68)){
movement = "right";
this._x += _root.speed;
}
}


However, if the "up" (87) is double pressed I want it to move double times the speed for a short second.

Is there any suggestions for this function?

That should help.

Excuse me for the asking incorrectly. I meant a double keyboard press/click not a double mouse click.

So I want it to detect a double <space> press as oppose to a sinlge <space> press.

it's the same idea swope MouseDown with Key.isDown, you might need to Key.addListener but it will work

This works well. Just modify the variables. If the fps if set to 30 then the person has 1/3 of a second to double click.

onClipEvent (load) {
c = 0;
}

onClipEvent (enterFrame) {
if (Key.isDown(Key.SPACE)) {
if (!down){
c += 20;
down = true;
}
} else {
down = false;
}

if (c>30) {
this._rotation = 90;
}
if (c>0){
c -= 1;
}
trace (c);
}
