Referring the code made by Mr.Shiffman, i found that he couldn’t explain the code for stopping the timer at 0, so could anyone help with it…-Johann

Link please! What video or example or book chapter etc. are you talking about? There are so many.
> explain the code for stopping the timer at 0
There are many kinds of timers, and many ways to stop them. Please give a longer explanation of what you are trying to do.
Also, is this a millisecond timer, or a frameCount timer, or a wall clock timer?
