Unity warned: NullReferenceException and the frog moved before pressed the space bar

When I played the sample game in unity, it warned "NullReferenceException" in "if (playerHealth.alive == false)". I checked the object "playerHealth" already and the frog is moved before pressed the space bar.

Best Regards

Hi Keen,

This sounds like a missing reference in the Inspector, but it's hard to tell without looking at the project. If you're still having trouble, post a zip file somewhere online and then paste the link here and I can take a look.

All the best, Nick
