Question

The goal of this assignment is to develop an event-based game. You are going to develop a Pong Game.

The game board is a rectangle with a ball bouncing around. On the right wall, you will have a rectangular paddle (1/3 of the wall height). The paddle moves with up and down arrows. Next to the game board, there will be a score board. It will show the count of goals, and count of hits to the paddle. In the beginning of the game, the paddle will be on the center of the right wall.

You can develop a two-player game, and it will count for extra 2 points bonus.

You can arrange the color and the style of the board/paddle/ball/Score Board as you prefer.

My Pong Game SCORE BOARD Goals Hits 10 25

Explanation / Answer

Please find my answer:

You need to understand that this is a very big assignment which is difficult to be completed in 2 hours (time we get to complete an assignment in Chegg).

For your reference, I am providing you a sample code for creating a Ball, one controller for Computer and one controller for a Player. You need to incrementally add changes to Game.java to construct the whole game.

You need to incrementally add features to this class.

****Note: Please create one more post on Chegg to implement Game.java and I will try to answer it.
