RoadManager class's move(int) method, call the move method on each object in the items list. Pass the sum of boost and the object's speed as the argument.

Question about the task

Resolved

Hi, What's wrong with lines 48-49 in RoadManager Class? I'm doing as in the instructions, passing the sum of the boost + object's speed. Thanks,

The RoadManager class's name isn't arbitrary: it manages all the obstacles on the road.
It must know how to draw and move all the stored objects.

In the RacerGame class, create a RoadManager roadManager field so you can access it.
Initialize the roadManager field in createGame(), and call draw(Game) on it in drawScene().

Requirements:

The RoadManager class must have a public void draw(Game) method.
In the RoadManager class's draw(Game) method, call the draw(Game) method on each object in the items list.
The RoadManager class must have a public void move(int boost) method.
In the RoadManager class's move(int) method, call the move method on each object in the items list. Pass the sum of boost and the object's speed as the argument.
The RacerGame class must have a private RoadManager roadManager field.
The roadManager field must be initialized with a new RoadManager object in the createGame() method before the call to the drawScene() method.
In the drawScene() method, the draw(Game) method must be called on the roadManager object. Pass this to the method.
In the drawScene() method, the draw(Game) method must be called on the roadManager object after the drawField() method.

Changing move method in RoadObject solves it: Instead:

public void move(int boost, List<RoadObject> RoadObjects) {
       this.y += boost;
   }

Replace with:

public void move(int boost) {
        this.y += boost;
    }
