Taking damage and possibly dying

Let's enhance the Player object to track health. Just like the goblin, let's start with 10 health, and if the goblin hits us, we will lose 5 health. If the Player is hit twice (unlikely, but possible), then the Player will die and be sent back to the MainScreen.

Let's also add a convenient function to apply damage to the Player's health. The modified Player class looks like this:

package docrob.cag.mygame.characters;

import lombok.*;

@NoArgsConstructor
@AllArgsConstructor
@Getter
@Setter
@ToString
public class Player {
    private String name;

    private int health;

    public Player(String name) {
        this.name = name;
        health = 10;
    }

    public boolean isAlive() {
        return health > 0;
    }

    public void takeDamage(int damage) {
        health -= damage;
        if(health < 0) {
            health = 0;
        }
    }
}

Next, let's modify the WestScreen's hitByGoblin method to damage the Player.

private void hitByGoblin() {
    System.out.println("You attack the goblin and MISS! The goblin punches you.");
    MyGame.getPlayer().takeDamage(5);
    if(!MyGame.getPlayer().isAlive()) {
        Game.getInstance().getInput().getString("You have died.\nPress Enter to continue.");
        MyGame.killPlayer();
        ScreenManager.addScreen(new MainScreen());
        setReadyToExit();
        return;
    }
    Game.getInstance().getInput().getString("Press Enter to continue.");
}

Run and test the game. You might change the value in attackGoblin from 75 to a smaller number like 10. This will increase the likelihood that you will miss the goblin and be damaged. Once you feel the code is working, be sure to change that number back to 75, unless you like restarting the game.

Next: winning the game
