Once a player misses the ball, the other player’s score is incremented by one.The up and down boundaries of the canvas will reflect the ball when the ball hits.The direction of the ball is changed and speed is increased a little when the ball touches a paddle.UP & DOWN arrow keys for the right player to move up and down respectively. W & S for the left player to move up and down respectively.
We move the paddles up and down using the keys on the keyboard.We’ll deploy a ball with an initial velocity and a direction at the center.We are using HTML5 canvas and JavaScript to implement this game.
