How do i compile greenfoot to .JAR?

Unfortunately, it is no longer possible in recent versions. However, most scenarios work a few versions back. Just download an older version of greenfoot (v26 iirc) and use the share button.

As a test I uploaded a scenario of a single ant being instanced and nothing else and that still resulted in an HTML5 issue, so it it the computer?
Maybe you should have left it up here for us to look over. Start simple and work up gradually to pinpoint where the problem begins. That is, start with no sound files, limited images and minimal code to get going. Share it to see if it uploads correctly. If not, it may be your computer, your version of greenfoot, or who knows. It loads, maybe add ONLY one music file and test it again. Then continue b
Artificial Inteligence
By CowboyIggy, with no replies.
I am creating a Chess game and would like to make the player vs computer option, but I don't have any idea how to create an Artificial Inteligence to play Chess. Sure using a lots of 'Ifs' wouldn't be the best way... Someone has any ideia or a link for some discussion that could help me in that way? I didn't try any code yet also, if I try in the next days I upload it here in this discussion.

Thanks danpost! That totally explains why the cows weren’t spawning — I had no idea the timer reset was messing with the later condition. I’ll go fix that now. Also, just wanted to say I haven’t been on Greenfoot for long, but I’ve already noticed how active and helpful you are. Your replies are quick, spot-on, and actually help people level up their code. Big respect — keep doing your thing!

The first four lines in your

Right. I am getting similar results after further testing. Maybe you should use a different method -- maybe the following for line 10: <Code Omitted>I get consistently correct results with this one.

What do you mean by 'call this new method from wolf/bear classes'?
I mean add the "new method" above,

Looks like I missed one case world: <Code Omitted> And actually, the final range is 1 to 36 as 49 is the character code for '1' (not 48) which shifts everything up by 1. (48 is the character code for a '0' (zero)).
Rhythm Game in Greenfoot?

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. Depending on what you want, add a timing system or some type of a scoring system, or both (controlled by the world). 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
