Issue with increasing speed of MC

Hi all,

I was wondering if someone could assist with an issue I'm having. I'm creating an interactive menu planner, which has a moving list of foods that move along a conveyer belt.

The user can hit a 'stop' button, that will stop the foods on the belt, which makes the food items drag-and-dropable.

Once they have selected the foods they want, they hit the 'go' button, and the foods begin moving along the belt again.

I've implemented it, and having running, but the issue I've run into is that every time I hit the 'go' button the speed of all the items increases ten fold. I've tried using timers, enter frame etc and all result in the same issue.

If someone could let me know where I'm going wrong, or a potential solution, it would be greatly appreciated.

Thank you in advance- and I apologise for the lack of commenting.

Because beltRun is called on every button click and because you have the same listener on stop and go clicks (you shouldn't btw), each time you click a button, a new ENTER_FRAME is created with the same action, so actually, on every frame you have the movement multiplied by the times you clicked the button so far.
Remove the listener from there and leave only the stop flag comparison for the rest of the function.

Cheers,

Fixed the issue- can't believe I missed that!
