You need to remove the import of "java.awt.Color" at the top of any class which won't compile. The Greenfoot API changed in version 3.1.0 and some older scenarios aren't compatible with it; full details here.

Also, I forgot to mention what I'm trying to accomplish is a rhythm game that gives point based on how close you pressed the button at the "Target" area. Right now the notes are Random but plan on making them sync to a beat later on. Here is an example of something similar to what i want to make: Youtube Link ]

You will need to track which direction the ship is currently moving. The speed is a constant and can be hard-coded or held in a field. The new y-coordinate of the ship in your setLocation line can then be expressed as 'getY()+dir*speed' or 'getY()+dir*5', for example. The 'dir' field, as an int, would hold a value of '1' or

That is because the bullet is not being removed when hitting a barrier. In the Bullet class hitBarrrier method (as last shown), add after line 4: <Code Omitted>

Thank you so much! I completely missed that. :) It works as expected now!

The getCount method is not in the World class -- but in a subclass of World. You must inform the compiler which type of world it is in. For example, if the subclass is named MyWorld, then: <Code Omitted>Note that the getWorld method of the Actor class returns a World object (or null), which could potentially be of any subclass of World.

Yes -- it is possible. No further help can be given with the limited information given (detail on game structure and what you are currently having difficulties with).

Oh - and you won't be able to update the file using that method. If you really want to keep high scores persistent, I suggest looking into the Java Preferences API. There's a brief tutorial here.

But thanks. :)

Seems like the name you use in your code is not the same as the name of the file (RIGHT vs. Right)

Like this?

There is also an issue with a stream of bullets instead of individual ones (a new one will be create for each act cycle the space key is held down. You will need a boolean field to track the state of the space key:
