Ping Pong Rhythm Smash

Initial prompt

Ping Pong Game Description for Upit AI: Create a simple 2D ping pong (table tennis) game with the following features: Game Setup: A 2D ping pong table with two paddles (player and opponent) and a ball. Player Controls: The player controls the paddle using left and right arrow keys (or optionally mouse). The opponent paddle moves automatically, tracking the ball’s horizontal position. Ball Mechanics: The ball moves continuously and bounces off the paddles and table edges. When the ball hits a paddle, it changes direction and speeds up slightly. The ball also slightly changes direction and speed in sync with music beats (for example, every second). This creates a “dancing ball” effect tied to the rhythm. Music Synchronization: The ball’s speed and direction react to music beats or rhythm, making the gameplay rhythmic and dynamic. Scoring System: Keep track of the player’s and opponent’s scores. Scores update when the ball passes beyond a paddle. Visuals and UI: Display the current scores on screen. Simple but clear 2D graphics for the paddles, ball, and table.
