How to make a back function using a keyboard key?

[solarboi]

the scenerio goes. I have 2 scenes. if i wan flash to play back the previous scene using a key eg. backspace, how do i go about doing it?

Another qns i would like to ask too.
for example. I have 3 scenes. A is the main scene, B is the 2nd and C is the third. The flash will play as follow. A, B, then back to A again then C. Is there any actionscript to do this?

Thx in advance to the scripters here :)

stage.addEventListener(KeyboardEvent.KEY_DOWN, downHandler);
function downHandler(event:KeyboardEvent):void {
if(event.keyCode == 8) { // IF backspace pressed
gotoAndPlay(1); // OR prevFrame();
}
}


I believe that should do it for the back button. This link will show you all of the key codes (you need to change the 8 to whatever number you need):

For the second question:

Make a boolean variable (for example var bVisited:boolean = false; )
then on scene 'A', right before you go to scene 'B' put the following:

if (bVisited) {
gotoAndPlay(C);
}
else {
gotoAndPlay(B);
}

and at the beginning of scene 'B' put:
bVisited = true;

i paste it but i have this error.

the class or interface 'KeyboardEvent' could not be loaded.

Are you using AS 3.0? If so, is the script in its own .as file?

[solarboi]

yap. using AS3.

sorry. i quite a newbie in this. dun mind me asking what do you mean by "the script in its own .as file?"

Here is a tip: if you don't know what he is talking about, you are not using it. He is talking about a separate class file.
