Button problems: Hitting my Back Button Once Stops my Project Completely

Report · Jan 26, 2013

Good morning, afternoon, and evening to you all!

The issue that I'm having seems silly. Please bear with me.

I have simple gotoAndStop(); buttons on this project I'm working on. On my title page, I have three of them, and on the pages corresponding to those buttons, I have but one button each; that's my back button, which is a simple gotoAndStop(1); button that executes when clicked. However, when I click on either one of my back buttons, the rest of my buttons simply stop working. Do I need to add my event listeners again?

My code:

public function main()
{

start_btn.addEventListener(MouseEvent.CLICK, clicker);

controlbtn.addEventListener(MouseEvent.CLICK, ctrls);

creditbtn.addEventListener(MouseEvent.CLICK, credit);

bacnbtn.addEventListener(MouseEvent.CLICK, back);

}

function ctrls(e:MouseEvent)
{

gotoAndStop(10);

}

function credit(e:MouseEvent)

{

gotoAndStop(9);

}

function clicker(e:MouseEvent)

{

gotoAndStop(2);

StartLevel();

}

function back(e:MouseEvent)

{

gotoAndStop(1);

}

Help? I need this fixed TODAY ASAP. Please.

Are you assigning all this code on frame 1? If so, if you go back to frame 1 you're piling on even more assignments and function definitions over and over.

You should assign the code in frame 1 and then start your while timeline on frame 2. Return back to that (e.g. gotoAndStop(2)) so you never re-run the same code again. Otherwise update the logic so it only runs once.

e.g. on frame 1:

if (!firstRun)
{
          // now on thsi frame this var exists forever and the code to assign never runs again
          var firstRun:Boolean = true;

          // I took 'public' off this as none of the other functions have
          // "class" specific access modifiers.. add it back if you're showing
          // a mix of class scripting and frame scripting
          function main()
          {
                    start_btn.addEventListener(MouseEvent.CLICK, clicker);
                    controlbtn.addEventListener(MouseEvent.CLICK, ctrls);
                    creditbtn.addEventListener(MouseEvent.CLICK, credit);
                    bacnbtn.addEventListener(MouseEvent.CLICK, back);
          }
          function ctrls(e:MouseEvent)
          {
                    gotoAndStop(10);
          }
          function credit(e:MouseEvent)
          {
                    gotoAndStop(9);
          }
          function clicker(e:MouseEvent)
          {
                    gotoAndStop(2);
                    StartLevel();
          }
function back(e:MouseEvent)
{
gotoAndStop(1);
}
}

Now upon returning to frame 1 functions won't be redefined (erroring) nor will assignments be added to buttons that already have them.
