Sorry for trowing something in your coffee.
When pause = off ... A double tap will switch it on .. then off (after a short time).
Clearly showing that the 'on tap' runs its actions, even when double tapped.
The easy solution is in my example.
WHY would you need to use double tap on the same object if double tap event is already running?
If you need that use single tap and just toggle the variable.
Tap and double tap are separate actions and used properly on the same sprite work as they are supposed to.
