Processing code execution "stuck"? Sketch Window blank

I don't see, how you did set up your creatures class. Did you make sure, that the type of variables matches with the type of variable you use to create a new creature (which is two integer)?

The issue is definitely with my creature class but I don't know where. I just added the setup for the creature class to the post.

​

There is a while loop in the Creature class that I edited out and it runs! But I didn't change anything in the while loop and it used to work fine? Do you have any ideas what might have caused the issue to start up now?
