I want to get information to print to the terminal about a specific object, but I can't tell which instance of the object the information is coming from.

Introduce an indentifying field into the CatClass class: <Code Omitted>Then add a constructor to the class to accept a name: <Code Omitted>Now, you can give the cats their names: <Code Omitted>For the print line command, you can now use:

<< Code Omitted >> What i wanted to do is to use a GreenfootImage to display the typed text. but i have no clue how to make the "name" in the method individual. My idea was to create a new object: << Code Omitted >> to do so. But i can´t figure out how to create on of this objects without giving the "text" in the code

"typed text"? where is the code that allows user input?

Is it a good idea to use Swing Timer? Does it affect the performance if I use it repeatedly?I use a swing timer like this: << Code Omitted

For anything to be uploaded onto the greenfoot site, all javax.swing classes should be avoided (same with java.awt classes). The "common way", as you put it, is more direct, works anywhere and has no chance of messing with the behavior of the greenfoot environment.

What does this error mean?

Are there any more lines in the stack trace? It's possible there's an error in the collision checker because it does use recursion but the stack overflow will probably involve more than three calls, so we'd need to see more of the trace. If you're willing to, zipping up the scenario and sending it to support@greenfoot.org would allow us to take a look.

Strange. After doing a bit of debugging, I found that bombBoom never returns true; it's always false, even when the bomb hits it. Is it supposed to do that? I would like to use this for my lives system, whenever the bombs hit the boomArea (bombBoom is now true. False is when the bomb is in the air falling down.)

Just fixed it as of now. The problem was that boomBoom was being called in the act method of boomArea.

I added bullet code to my character but I don't know how to make my character shoot in the direction of which my character is facing. I have tried about anything on the internet but nothing seems to work. << Code Omitted >>

The rotation of your Soldaat actor never changes;, so getRotation() will always return zero at line 32. Bullet on line 32 is a Class

Is it possible for the wombats to move diagonally? << Code Omitted >>

You would need to change line 48 to: <Code Omitted>and add the appropriate cases to the switch block in the canMove method. However, once an edge is reached, it will turn twice to go along each edge, anyway. Maybe adding a random turn to the code would help: <Code Omitted>

Variable from MyWorld

I'm not sure how, but I treat my actors like Variables. ... how do I figure out what case random has been assigned to? e.g If random followed case 2 (as I already said that the actor paper has to be pressed), the IF statement will mean that scissor's actor will be removed.

Place your actors in an array field: <Code Omitted>They will each now have a number associated with them: <Code Omitted>Your act method can then start wit
