This should work. Change the 'itemStateChanged' method to this: <Code Omitted>Appending the following to your 'actionPerformed' method should solve the rest:

thanks a lot! now it works.

Thanks! I had the first letters capitalized in the code, but not in the files so I didn't notice.

<Code Omitted> This is covered in tutorial #6

Awesome thank you so much that works! :D Thanks! <Image Omitted>

Input (as far as computers are concerned) is defined as any means by which external data is supplied to a program. This can be, for some examples, through reading of a disk file, input from the keyboard, or through a network link. If the console contains data, then some program supplied that data to it. Your keystrokes do not magically appear on the console and your program does acquire data from the console. It is NOT an input device. Maybe these other environments have underlying code that takes your keyboard input and displays (or outputs) it to the console. It would not be difficult

i told you it was a dumb question ;-) thanks a lot! that solved the problem.

I take it that PlayerChar is a class. When you say 'PlayerChar.getX()', you are asking, therefore, for the location of a class. Classes do not have a location. Actors - i.e. instances of classes - have a location. You need to get a reference to the PlayerChar actor that you want the location of, and call getX() on that. See for example tutorial #6.

Nvm i fixed it lol <Code Omitted>needs to be <Code Omitted>

Thanks for the help.

This is telling you that you are attempting to de-reference a null reference on line 93 of your Greeps class. First step: look at the line and see what might be null. <Code Omitted> ... the only thing on the left-hand-side of a dot operator is 'getWorld()', so that must be returning null. Which means: your object isn't in any world. Which probably means: your 'Small' subclass is removing 'this' instance from the world before it calls the 'move

Thank You that worked ;) awesome!!

thanks it works

Thanks Hippo, I've got it working now :)

Ah, thanks, it works!
