I have a world with settings for my game. In this world you should be able to click on a button and change the background of the world where the main game is. But I don´t know how to change the Background of the gameworld when the Actor is not in this world.

Store the String filename of the background image in a field in your settings world. When creating the game world, set its image right there before setting the game world active.

How could the World actually work?

By KlausKrieger, with 3 replies.
Last reply by RcCookie, over 4 years ago:

No problem:-) Concerning the change of the world, this might also help: Every frame of the Greenfoot application the current world gets rendered by (simplified) stacking the images of all the actors on top of the worlds background image. If the world changes, the images used to render will simply look different on the next frame, which results in the world being switched visually. Additionally, Simulation will call act on the new world.

somehow my ghost wont rotate anymore at the given points... Eventhough I used getImage().rotate instead of set Rotation.

Do NOT rotate the image. Maybe I misunderstood what you were trying to do. Please explain, in detail, what behavior you are trying to achieve.

For loops not working

By BeeSauce, with 1 reply.
Replied to by RcCookie, over 4 years ago:

I assume "Wait" is initially 0. And 25ms is not a quarter of a second but a fourteeth. You should use 250 there. But that is not the main problem. The thing is the first for-loop can run really quickly, and only if it is very slow (taking the 25ms) it would spawn another instance. The much simpler solution here is using Greenfoot.delay(int) where the number specifies the number of time steps to delay. The lenght of one time step can be adjusted using the ui slider or using Greenfoot.setSpeed(int). Example implementaion:
