there must be a situation when you see it wandering from right to left and seeing that the background image below is resting. But from beginning on it works perfekt and everything is wandering perfect without seeing something resting in the background ..... That is perfect, but it is not clear to me why it is so perfect ...

I am not sure what you mean by "image below is resting". If you want clarification on some point, you will have to be more specific, show all codes used for scrolling (other than the Scroller class itself (which should not be modified

Games are the easiest way for a beginner to practice programming though. At least that's my opinion.

Yes, but one must first become familiar with the basics of the java language and what methods are available in the classes provided in the greenfoot package. Looking through the API documentation of the classes should help immensely in the latter, and the java tutorials should help with the former. Then trial and error programming will help in learning what is possible as well as how to accomplish things. This last part can be done while creating your game;

Counter not working

You create a Car object, but show a cars class. Cannot do anything about the counter until it is known what you are doing there. Remove act(); from the Level2 class constructor and then take the first 3 lines in act and move them to the prepare method.

I want my screen to automatically scroll into the according direction when I hover my mouse over the bottum/top/right/left.

Please refer to my Scrolling Tutorial scenario. It does not specifically cover mouse-at-edge action, but other than that, it will not be any different.

Contact during the whole time if object1 via object2

I want whoever a lobster sees a crab to only get one life ripped off. The problem is that the crab "crawls" over the lobster and has about 5 times contact = lifetime is deducted.

Your solution might work (with some minor adjustments) if not for two issues. The first one is that you probably have multiple lobsters in the world. A boolean field like hits would only detect (a) crab intersect any, but unknown, lobster; or (b) crab not touching any at all. That is, it does not track which lobster is intersecting. So, if a 2nd one touches while one is already inte

Hide cursor in Greenfoot 3.5.0 onwards

By AlexDascalu, with no replies.

I am trying to update the code for a Greenfoot game I made so that the mouse cursor is hidden. In previous version I manage to do that with some Swing code but since 3.5.0 switched from Swing to JavaFX that code no longer works. I know how to set the cursor if I have a reference to the JavaFX Scene, and I have found in the source code the GreenfootStage class which extends Stage, but I can not find a way to access the GreenfootStage of the game. Can anyone please help me?

I have coded the button to disappear on touch but I cant figure out how to make the coins spawn in when the button disappears. I don't know what code to show so if you need any just let me know.

Show any and all codes related to the button. Also include any attempt to spawn the coins when the button disappears or provide what ideas you might have for implementing it.

How to hide actors in the left pane

By AlexDascalu, with no replies.

Hello! I have made a game in Greenfoot that is intended to be used for educational purposes, and I am trying to find a way to hide some of the actors of my game from showing up in the left pane of Greenfoot, so as to make the game less intimidating to a pupil. I could not find anything like that in the API or on the Internet. Does anyone know if there is a way to do that?

Cant find symbol (variable disk)

if(disk!=null) <------ says it "cannot find symbol" here as well ... arena.removeObject(disk); <------- says that it cannot find symbol here

Apparently, you have not initialized a variable called disk before trying to reference it: <Code Omitted>Once it is initialized, you will need an assignment statement: <Code Omitted>to possibly acquire a reference to a disk object. Then your if statement will have a chance to be true as well as false (provided your assignment may or may not actually a

No code, no details -- No help. Always include related codes and specifics. The code should include some attempt at trying to accomplish what you are having difficulty with.
