ActionScript 3 after seven buttons clicked go to next scene - function

Question

I have seven buttons (btn_one, btn_two, btn_three, ...) and when all of them were clicked (not in a row, just random) I want go to the first frame in the next scene. What does my code should look like?
Thank you!

Answer 1

const buttons:Array = [btn_one, btn_two, btn_three, btn_four, btn_five, btn_six, btn_seven];
// dictionary to keep clicks state
const clicked:Dictionary = new Dictionary();
function buttonClickHandler(event:Event):void {
// record specific button's click to a dictionary
clicked[event.currentTarget] = true;
// true, if all the dict keys have true values
const allButtonsClicked:Boolean = buttons.every(
function(button:Object, ...rest):Boolean {
return clicked[button];
});
if (allButtonsClicked) {
// remove all listeners
for each (var button:DisplayObject in buttons) {
button.removeEventListener(MouseEvent.CLICK, buttonClickHandler);
}
//do whatever action you need. For example:
gotoAndStop(/*neededFrame*/);
}
}
// initialize dictionary values, and add listeners
for each (var button:DisplayObject in buttons) {
clicked[button] = false;
button.addEventListener(MouseEvent.CLICK, buttonClickHandler);
}
haven't tested, it but should work. Anyway, the scheme should be valid.

Answer 2

stop();
const buttons:Array = [btn_one, btn_two, btn_three, btn_four, btn_five, btn_six, btn_seven];
// dictionary to keep clicks state
const clicked:Dictionary = new Dictionary();
function buttonClickHandler(event:Event):void {
// record specific button's click to a dictionary
clicked[event.currentTarget] = true;
// true, if all the dict keys have true values
const allButtonsClicked:Boolean = buttons.every(
function(button:Object, ...rest):Boolean {
return clicked[button];
});
if (allButtonsClicked) {
// remove all listeners
for each (var button:DisplayObject in buttons) {
button.removeEventListener(MouseEvent.CLICK, buttonClickHandler);
}
//do whatever action you need. For example:
gotoAndStop(2);
}
}
// initialize dictionary values, and add listeners
for (var button:DisplayObject in buttons) {
clicked[button] = false;
btn_one.addEventListener(MouseEvent.CLICK, buttonClickHandler);
btn_two.addEventListener(MouseEvent.CLICK, buttonClickHandler);
btn_three.addEventListener(MouseEvent.CLICK, buttonClickHandler);
btn_four.addEventListener(MouseEvent.CLICK, buttonClickHandler);
btn_five.addEventListener(MouseEvent.CLICK, buttonClickHandler);
btn_six.addEventListener(MouseEvent.CLICK, buttonClickHandler);
btn_seven.addEventListener(MouseEvent.CLICK, buttonClickHandler);
}
I tested the code of leetwinski and added the eventlisteners for my buttons, but it doesn't work. I get the error "1067: Implicit coercion of a value of type Class to an unrelated type flash.display:DisplayObject" What did I do wrong?
