Oddly, this works now too :D Maybe i misspelled. Thanks again for your help!

This page of the Java tutorials might help.

Again, I cannot tell where this act method is with it by itself like that. I will say this much, however. It appears you are trying to create and start a new world by changing the background image of the first world. If you are, it is not done that way. It would still be the first world with a different background image; and, the constructor of the second world would never be executed. You need to use 'new background2()' to create a 'background2' world. You can create and set one active using 'Greenfoot.setWorld(new background2());'.

nevermind I didn't see he wanted to start a new method. I thought he wanted to make a boolean my bad.

You could size down the pictures and only show every other picture. This would reduce the load on the heap space dramatically. At a size of (400x300px) showing only half the pictures, you will reduce the load by over 87 percent.

I think that it is indeed the problem (although, it could possibly be something else. Remove 'images/' from the filenames in the 'setImage' lines (unless you have a folder called 'images' inside the 'images' folder in your project directory. On the other hand, you did not mention any exception throws or error messages which leads me to believe that either you are not being very helpful in describing your problems or something else is creating the problem to begin with.

Show what you tried so we can help fix it.

That would depend on how you move the actor to begin with. Post the class code of the actor (use the 'code' link below the reply box to insert code into your posts).

I will change it after I finish my code, I still need to code that bit. So for now I use 1==1. Just to check if the code works.

BTW, if both of the objects (the Held object and the Gegner1 object) are fixed at their initial locations in the world, then you can just use (50, 0).

I understand thank you !

Ahh I fixed it. Here's the solution: Constructor: <Code Omitted>and click: <Code Omitted>

Thank you so much. It works now
