Move line 41 down a line or two. The getWorld call needs to be before that line since when the actor is removed from the world, it will have no world to get.

Also just by way of suggestion you can cut your code by at least half if you use an Array, and For loops to place them in the world. like this: <Code Omitted>to instantiate them use a For loop like this: << Code Omitted >> to add them in to the world use this loop << Code Omitted >>
The quoted line of code should be: <Code Omitted>and I would have done the rest with:

Remove the first word from line 21. You do not want to declare a new variable there. You want to refer to the field declared on line 3.

I want to make the weapon dissapear after I grab (or should i say touched) it and make it appear on my character. I used if touching and then transparancy to 0 but with that code I can't make the weapon follow my character around because if I touched it. It will dissapear.
True that you cannot have it both disappear and appear at the same time. So ... why make it disappear at all?

I am making a game similar to Agar.io and I am having issues with my actor following the mouse in the scrolling world. Anyone know how do scroll using the mouse?
Program the actor to follow the mouse without regards to the scrolling. Then, scroll the world depending on the actor's position.

Exporting standalone to Raspberry pi (Raspbian)

By Higgins1904, with no replies.
Hi, I have done a simple Greenfoot project at my Win 10 computer, runs fine in the Greenfoot GUI version 3.6.0. Now I want to export it and run it at my Raspberry pi 4 (Raspbian) that has the Java version 11.0.5. I read at the export info page here that one need to tinker with the command line arguments when executing the exported jar-file. Anyone that knows what needs to be done? I try to run it with the following command line: java -jar /home/pi/test.jar I get an error message saying that the class greenfoot.export.GreenfootScenarioApplication is missing or could not be loaded. The file is there in the jar file, at the path greenfoot.export, I can see that when inspecting the contents of the package. Both my Pi and my Win 10 computer runs Java 11
