It is just there so you can see which is which easier. You can also change those colors or remove them completely. For background: Green is code for classes, yellow for methods, red for loops and blue for any other code blocks such as "if". White is the rest. For code itself: variable types (int, bytes, also return type void) and class/extends/... are red, some keywords (this, null, …) are blue, others (instanceof) are yellow. Access modifiers (private, public, …) are purple. Comments are blue or gray and the rest is black.

Okay -- yes. The WorldCanvas object was a JPanel object (a swing object) acquired via the WorldHandler object. The Cursor and Toolkit classes are both part of the java.awt package. I am not even sure if it is possible to acquire the world canvas in the later versions of greenfoot to begin with.

You could try this: Actor variable name = (subclass name) getOneIntersectingObject(subclass name.class);

See, that's what I'm trying to do.

Thanks. I hope to use this next time.

There should be no problems with using isKeyDown here. However, best would be to control turn phase in your World subclass, not only because it is a function of the game itself (not the individual players), but also because you will only require one field instead of two.

You need a reference to the GreenfootSound object which is playing. So when creating it, make sure you keep a reference to it or you will never be able to do anything with it afterwards.

ok ill go back and use the other thread

You need half of the sum of the height of both actor's images. So basically: <Code Omitted>with "obj" = the object which was intersected.

Show the class code of the actor which leaves the world. In your world, you don't have anything which would prevent objects from moving outside the world boundaries.

Please see my Scrolling Tutorial scenario.

My IQ is so high lol

Thank you it works.

Put this into the world's constructor. <Code Omitted>
