You may have noticed that if the timer was already running, you got one more batch of zombie
bunnies before they stopped reproducing. The flag is used before the timer is reset. You can easily
add a return clause to the
PopulateGardenBunnies()
function.
In the SpawnBunnies script, at the top of the
PopulateGardenBunnies
function, add the following:
10.
if (!canReproduce) return; // cancel the latest population explosion
11.
Save the script.
12.
Click Play, and test the result.
