im using actionscript 2.0, in flash 8, so can anyone help me?

Use the keyUp clip event or listener if you want it to be triggered only once.

onClipEvent(keyUp) {
    trace(Key.getCode())
}

But if you want it to be triggered only once and when it is pressed (not released), then set a boolean to true when it is pressed.

onClipEvent(load) {
    this._key_pressed = false
}
onClipEvent(keyDown) {
    if (this._key_pressed == false) {
        trace('key pressed: ' + Key.getCode())
        this._key_pressed = true
    }
}
onClipEvent(keyUp) {
    this._key_pressed = false
}

thanks, but how do i use it in a script tho?

also, can you please send me a full script like this, but with the script you replied with? to make my character move forever when a key is only pressed?

here is the script:

onClipEvent(enterFrame) {

if(Key.isDown(Key.LEFT)) {

this._x -=5;

}

if(Key.isDown(Key.RIGHT)) {

this._x +=5;

}

if(Key.isDown(Key.UP)) {

this._y -=5;

}

if(Key.isDown(Key.DOWN)) {

this._y +=5;

}

}

just replace the "this._x +=5;" or "this._y +=5;" parts with your script, thanks!

You can create a variable like "_X_key_pressed" for each key you want to have pressed, or use an Object to store those details - and then use an IF condition to check whether those keys have been pressed or not.

Two things:

1. I won't program your game for you, and
2. "Making the character move forever when a key is only pressed" is very different from the title of the question. Including the original answer in your script would have the character move only once when a key was pressed.

can someone also tell how to do this but in construct 2?

alright, thanks
