If you don't initialize paused it's undefined whether it will be trur or false.
Also if you have a global window, you have a bad design and possibility of certain things going wrong. I advise you to not use global variables at all.
Other than that, the code is incomplete and we can't tell you much more. Provide a minimal and compilable example instead.
sorry, i think id better post the rest of the code. Dont worry everything isnt global, its the name of the class those are in
(i know my code design isnt perfect, but thats more of why im building this, to learn
)
