Oh ist named miniminecraft

just write in act() <Code Omitted>instead of Five, you can use any number. Play around whith different settigs ;-)

You are not resetting touchingTrash back to false when you are no longer touching the trash. So the health would only decrease once in the above code (after danpost's suggestion which clears up another issue). You need to add an else on the if (Trash != null) to set touchingTrash to false.

I did not say that. In fact you did create one. You just did not add it into the world.

In your atEdge method, your conjunction is wrong. Using '&&', you are restricting the check to the corner where the two edges meet. Also, you should probably be using '>=" as the actor could pass right over either of the exact given coordinate (although, I do not see why you check along the x-axis at the right edge since the actor only moves straight down).

it appears and I can click on "add new subclass", then it loads and.. does nothing, popup menu stays

I deleted my part with the brighter()/darker() method and solved my issue with a simple inside black circle, that indicates the pen up status. Thanks for your help

I may want to migrate my project unto your project, as the implementation into mine is getting clunky and awkward.

It does not matter what your World subclass name is. All instances of subclasses of World are still World objects. So, the code need not be changed if you change the name of the World subclass. Now, although not necessary, you could be more specific as to what type world it actually is by changing line 2 to the following: <Code Omitted>This de

Hmmm I can't see a way that setLocation can remove the actor from the world, though. Sorry for all the hassle, but would you be willing to send us the scenario for us to try it out? This looks like a bug in Greenfoot as that exception shouldn't be thrown, but I'm struggling to see exactly how it happens at the moment. If you are happy to email the zipped scenario to support@greenfoot.org then we will take a look, fix anything on our end, and also advise you on a work-around.

It works now! All I had to do was change it to equal 4 instead of 5. Thank you all!

You will need to provide more code. The full class of the actor and possibly your World subclass as well.

This may be an issue with Java version. If you are double-clicking the JAR in Windows, it will use whatever version of Java happens to be the primary version on your machine. If this is not Java 8 (especially if it's Java 9 or later), that won't currently work well with Greenfoot's exported JARs, which currently only work with Java 8 (until we update to Java 9+ in future). Best work-around is to use a batch file as you describe -- you can try changing which Java is associated with .jar files but it's probably more trouble than it's worth, especially if other applications on your system need

This is a hack that we don't officially support... but having said that, the code looks like it should work. Technically you should add the focus listener on the JavaFX thread but I doubt that is the issue. If you run the exported program from the command line, do you see any exceptions in the console? Maybe add some System.out.println lines to check which parts of the code are reached.
