Question by ravery90 · Apr 21, 2020 at 10:13 AM · crashwebglchrome

Why is "PlayerLoop internal function has been called recursively"?

I have a project with three scenes: MainMenu, MainGame, and Tutorial. Both MainMenu and Tutorial work, but when I do a single click in the MainGame, it crashes on a WebGL build. Here is the Chrome console output after it crashes:

This won't happen when I debug the game within Unity, but when I do a WebGL Development Build (and regular Build), it will give this error. I've tracked my memory usage and I don't ever see it peek at any point. What could be causing this?

Thanks!

So, I figured out what the problem (sorta) was. For one of my prefabs, instead of an image, I used Unity's engine to make the sprite shape. So, I took a screenshot of that and created a new sprite with the new screenshotted sprite image.

Why does this cause this? Not sure. But once I created the new prefab sprite, everything worked.

Thank you, man. Your post fixed my headache)) I just started using new 2019 version of unity, saw this new Sprite Shape and thought it would be a good idea to use it for my simple project.
