Okay, no need for the

class. Then you can use something like the following in the
Bear
and
Wolf
classes: <Code Omitted>

As always, start with the basics -- your
World
subclass and
Actor
classes. Actors should interact or positioned to determine when a user action is to be executed.

If you have specific problems with the code, then show codes, indicate how it is not doing what you want and what you do want.
Hey, thanks for the response! Maybe I should've been a bit more specific with my question; I see that now. I have a general idea of how all the main f

when the player gets attacked by the enemies and the enemies reduce the players health to 0 or lower than 0 the game just stops and the terminal window pops up. Also the healthbar does not drop down to 0 after the final blow, but the game stops anyway, which is the bigger problem. << Code Omitted >> I would be super super thankful if anybody could help me because our teacher told us not to ask him for help
What did the terminal window display? (copy/paste output and error messages) You could remove the try/catch block from lines 387 to 396. If an error occurs ther

Thank you for the help. I made those changes and reuploaded but it still seems to be giving the INFO: Running TeaVM error. Still not really sure what it could be.
Sorry it didn't help. Maybe try making the
ArrayList
assignments in the constructor instead of in the declaration lines.

You are referencing files in a manner that does not conform to the javascript translation. You are using file directory names, "sounds" and "images", followed by double back slashes, In Asteroid and Laser classes. Remove the directory names (and slashes) and just use the filename itself.
