made the changes for compatibility with new Greenfoot (java.awt.Color is no longer acceptable vs greenfoot.Color it seems)

Actually, it is javascript security measures that disallow any use of java.awt and javax.swing packages.

It also seems as though the jar files are still hosted on the Greenfoot server, just hidden from view.

I am not too sure on that. I was under the understanding that they were not uploaded to the site when the source code was not included as per a Greenfoot team member.

Black screen with truncated error: "lass: java.lang.RuntimeException - (JavaScrip"

By lmoellendorf, with 1 reply.

To track down the cause of the `RuntimeException` I added some `System.out.println("start of Intro()")` statements to the constructor of my initial world class. They should have shown up in the browser console. But they did not. So I figured the issue must be in the static code of my initial world class. By trial and error I found out it was the `static final` keywords for the world background `GreefootImage` and GreenfootSound`. Here is a diff:

need help << Code Omitted >>

The only thing I see wrong with your codes is in the second line of the prepareBoard method, which should increment the column (c) value, not the row (r) value. Don't really know what you need help with. You need to explain (in English, please) what you are trying to do and how the execution is wrong.

I think if this last error is solved, it will function?

My mistake. Line 28 should be: <Code Omitted> My last edit to change methods still stands as it should not matter which world is currently active here. The referencing bypasses that issue. And, it should have nothing to do with actor not in world as act method is not executed when not in world.

Between the time I posted that and your reply, I searched far and wide for a solution and ended up basically revamping a lot of the code. Good news tho

I was wondering if there was any way to get a random subclass? like, say i had a subclass of actor and then 3 subclasses of that subclass, and i wanted to select a random one of those 3 to display on the screen. is that possible?

Here is an example method using mock class names. The return type can be modified to be the parent class name.

I wanna add Hearts that function as Lives into my game and I have done that by creating three different heart actors (Named Heart, Heartt and Hearttt) but now I want those Hearts to disappear if my Player touches an object (in this Case a bomb) and reappear when my player touches another object (in this case a strawberry). Can anyone help me with how I could make it so if my player touches a bomb one heart disappears and if my player touches a strawberry one heart reappears ??
