i got it to work, thank you for replying though. What do you mean by if it is not under another actor. Are you talking about the side panel to the right and the ordering of the actors?

I´m doing this for a school project so I have absolutely 0 knowledge. I simply changed the image of my class, however it won´t move, even though it moved correctly before and I´m not sure why. It says there´s no errors as well
Please show class codes for object in question.
This is spawned when an enemy is killed. This code lags in HTML5 for 0.5 seconds but not when run locally. Gifs do the exact same thing. Is it possible to fix this online?

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.

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.
Feedback on Game Request

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

Okay, no need for the
