How to start a timer only on a certain scene??

hipponose · February 2018

Hi I'm making a game where I need a timer but it only starts on a certain scene. I need the timer (timer.start()) to start only on level 1. Thanks for the help!

Tell me if you need the extra tabs. :-h

Looks like you are using the timer library by @Lord_of_the_Galaxy

I see you have created this function:

void checkForTimer() {
  if (scene == "level1") {
    timer.start();
  }
}

Do you ever call this function anywhere?

No, but I'm not sure where to place it... In the draw?? Or in a certain scene?

jeremydouglass · February 2018

Well, when do you want to start the timer? Describe exactly what you want to happen.

hipponose · February 2018

Hi, I found out how to solve the problem! I start the timer in setup() and use timer.reset() in the scene I want!! Thanks for the help!

jeremydouglass · February 2018

Great job, @hipponose -- and thanks for sharing how you solved it.

Lord_of_the_Galaxy · February 2018

Thanks for helping out @jeremydouglass I'd completely forgotten that I'd written a library :P

Howdy, Stranger!
