Store your updated "Adventure Game" code in a file named AdventureGameFinal.java. Store your classes in the files Player.java, Enemy.java, and Weapon.java. The focus of this assignment is: (1) defining classes; and (2) using objects. New Features You will add three new features to the original game. 1. Improved Pacing (Note; this is a featured that you implemented in Assignment 3) Improve the pacing of the game by prompting the player to hit a key after each minion (i.e. Goblin/Skeleton) fight. So when the player battles multiple minions, instead of simulating all the fights and printing all the outputs together, the first fight will be simulated and its results printed, but then the user will be prompted to hit the Enter key to continue to the next fight. 2. A New, Powerful Weapon In addition to the option of choosing a Healing Potion or a Ring of Strength, present the player with a third option: Staff of Power. Weapon Name: Staff of Power Damage: 5 -9 3. Variable Number of Goblins/Skeletons The number of goblins will be a random number in the range 2-5. The number of skeletons will be a random number in the range 3 - 7
