Removing/Resetting Timers for Game

[cyb3ria]

Greetings fellow Flashdevelopers

My friend and I are trying to create a small Flash game for school but we're stuck trying to reset it when you have a Game Over.

The timers keep going on the Game Over screen and when you press the back button they keep going on the menu screen aswell.

We're trying to look for a solution to fix the issue.

We're also trying to find out how you make the game completely reset when you press the back button, so that you can start a new game without any issues.

This is the AS3 script we wrote for the game. I highlighted the places in red where we tried to write some code for the Game Over screen.

You have a lot of ENTER_FRAME event listeners at work, at least one of which is telling the Timer to start().  YOu need to remove them if you want to start fresh and stop the Timer(s).

Alright! That works. Is there a way to delete the objects that are on the screen? I removed the ENTER_FRAME events in the red part of the code.

I have some issues with the music aswel. It just replays the track over the first one, so the track is playing 2 times at the same time.

Thanks for the help Ned, We really Appreciate it.

If the objects you want to remove were added dynamically then remove them dynamically using removeChild() and null any references to them.

As far as sound goes, if you use the Sound class you should have complete control over when sound plays and when it doesn't.... if you are placing sounds in the timeline, not so much control is possible..
