So I need to create two public methods into the "MyWorld" class, on for music.play and a second one for music.stop? And what do you mean by "cast" to your World? Thank you.
You would only need to create public method(s) if the GreenfootSound object was private. That is, as public, the GreenfootSound object would already be accessible; otherwise, you would need public method(s) to make them accessible (either with a getter method or with action method(s) to control the sound). As a public field, an actor in the world can get a reference to the GreenfootSound object with: <Code Omitted>which can be shortened to this: <Code Omitted>This presumes you named the GreenfootSound object in MyWorld as music: <Code Omitted> Actually, if you refrain from stopping the scenario in the actor class, you could add the following act method in the MyWorld class: <Code Omitted>and the music field can be made private (with no getter or action methods needed for the GreenfootSound object).

If you have actors and references to them, then: <Code Omitted>will be true if actor is in the world (and false, if not).

Ok, so now i've pasted the code in the beginning of the code of my actor "player1". So, what do I write in another actors code so that the actor changes p by (as example) 1?
Depends. If during colliion detection: <Code Omitted>Without collision detection, you will have to go through the world: <Code Omitted>
