Calling World public method with actor as a parameter

So I need to create a new class called ActorIcon and put the code you gave me inside, right?

Yes.

And how do I call the class ActorIcon to work in myWorld?

Create them as you create the game actors that require instrument actors. Use the following example as a format:

Violin violin = new Violin(); // create game actor
ActorIcon icon = new ActorIcon(violin); // create instrument actor
addObject(icon, 20, 90); // add instrument actor to world
addObject(violin, << wherever >>); // add game actor to world

ActorIcon icon = new ActorIcon(violin); // create instrument actor
addObject(icon, 20, 90); // add instrument actor to world
addObject(violin, << wherever >>); // add game actor to world

When I put : ActorIcon icon= new ActorIcon(violin); it highlights the word violin and says that "cannot find symbol- variable violin"

In MyWorld I have:

Violin violin = new Violin();
addObject( violin,x ,y); // actor in game

ActorIcon icon = new ActorIcon(violin);
addObject(icon, 20,90);

and the method:

public void instrumentsTransparency(Actor Instrument,int t)
    {
       Instrument.getImage().setTransparency(t);
    }

And in the class ActorIcon:

public class ActorIcon extends Actor
{
    //field for linked actor
    private Actor linked;
 
    //constructor
    public ActorIcon(Actor link)
   {
       linked = link; // retain linked actor
       setImage(new GreenfootImage(linked.getImage())); // assume a likeness of image of actor
       getImage().setTransparency(50); // fade image
   }
   
    public void act()
   {
    if (linked != null && linked .getWorld() == null) // if linked actor is collected
    {
        linked = null; // reference no longer needed
        getImage().setTransparency(255); // illuminate
    }
   }
}

And on the Player 2 class:

public void lookForBonusPoints()
    {
        if(isTouching(Violin.class))
        {
            MyWorld world = getWorldOfType(MyWorld.class);
            world.instrumentsTransparency(world.violin,255);
            removeTouching(Violin.class);
        }
    }

I think you do not need lines 5 and 6 in the method lookForBonusPoints since the transparency gets taken care of in the ActorIcon class (that was the point). All Player2 needs to do is remove the Object (Violin). (See ActorIcon.act(ActorIcon.java:16))

P. S. You didn't show any more code than what has already been displayed in this discussion, the point was to copy the whole class code and paste it here.

The "new ActorIcon" doesn't accept the variable violin It says that "cannot find symbol- variable violin"

Where did you try to use this line of code? You will need to remove at minimum in your MyWorld class lines 6, line 51, lines 132 through 152 and lines 170 through 190. Then line 89 will need to use my example code for adding the Viiolin object. The other objects (Tambourine, Mandolin, Congal and Saxophone) should be added (at lines 77, 81, 85 and 93) similar to that of the Violin object.
