ADF1 - Interface

Today, game is an important industrial of software, one of most important features that a game must have is the extensible capacity. As an architect, you know the meaning of “implement into interface not into implementation”, so you must:

Create an interface for actor that can do :

- forward()

- jump()

- blink()

Code:

• Interface:

public interface Action

{

    public void Forward();

    

    public void Blink();

    

    public void Jump();

}

• Class Actor:

public class Actor implements Action

{

    private Circle face;

    private Circle leftEye;

    private Circle rightEye;

    private Triangle mouth;

  

    

    public Actor(){

        

        face = new Circle();

        face.makeVisible();

        face.changeSize(70);

        face.moveHorizontal(107);

        face.moveVertical(100);

        face.changeColor("yellow");

        

        leftEye = new Circle();

        leftEye.makeVisible();

        leftEye.changeSize(15);

        leftEye.moveHorizontal(120);

        leftEye.moveVertical(120);

        leftEye.changeColor("black");

        

        rightEye = new Circle();

        rightEye.makeVisible();

        rightEye.changeSize(15);

        rightEye.moveHorizontal(150);

        rightEye.moveVertical(120);

        rightEye.changeColor("black");

        

        mouth = new Triangle();

        mouth.makeVisible();

        mouth.changeSize(8,30);

        mouth.moveHorizontal(112);

        mouth.moveVertical(192);

        mouth.changeColor("brown");

    }

    

    public void Forward(){

        face.moveHorizontal(100);

        leftEye.moveHorizontal(100);

        rightEye.moveHorizontal(100);

        mouth.moveHorizontal(100);        

    }

    

    public void Jump(){

        face.moveVertical(-100);

        leftEye.moveVertical(-100);

        rightEye.moveVertical(-100);

        mouth.moveVertical(-100);

        face.moveVertical(100);

        leftEye.moveVertical(100);

        rightEye.moveVertical(100);

        mouth.moveVertical(100);

    }

    

    public void Blink(){

        face.makeInvisible();

        leftEye.makeInvisible();

        rightEye.makeInvisible();

        mouth.makeInvisible();

        

        face.moveHorizontal(100);

        leftEye.moveHorizontal(100);

        rightEye.moveHorizontal(100);

        mouth.moveHorizontal(100);

        

        face.makeVisible();

        leftEye.makeVisible();

        rightEye.makeVisible();

        mouth.makeVisible();

    }
