Build a Digital Pet Game - "excessive period of idle time"?

Curriculum Help
1

Tell us what’s happening:

Hello, I have two failing tests related to “idle time”:

  1. The Hunger stat should be 100 after an excessive period of idle time.

  2. The Happiness stat should be 0 after an excessive period of idle time.

What exactly constitutes as “an excessive period of idle time”?

I tried adding a setInterval to increment/decrement the stats if no recent change occurred but that code made the test runner stall out. All other tests are passing.

Any help appreciated, thanks!

Your code so far

Hi @alexwilliams4

Good question!

Play a game in the example project, then count how many seconds it takes for the stats to change.

Happy coding

This is the last thing I need to fix as well. Did you figure it out? using setInterval() seems to crash the test because it just keeps loading.
