2D Infinite Runner Game on DE10-Lite

Overview

This project is a 2D infinite runner game where the player controls a character to jump over randomly generated obstacles. Inspired by the Google Chrome dinosaur game, it features real-time scorekeeping, VGA display output, and gameplay controls using the DE10-Lite board's buttons and switches.

Features

• Real-time Score Display: Seven-segment displays show the score in decimal format.
• Player Controls:
  • Jump Button: Triggers the player's jump.
  • Reset Button: Resets the score or starts a new game.
  • Pause Switch: Pauses/resumes the game.
• Game Elements:
  • Player gravity and collision detection.
  • Randomized obstacle generation (height and delay).
• VGA Output: Smooth 60 FPS display with 640x480 resolution and 4-bit RGB sprites.
• Phase Locked Loop (PLL): Ensures a 25MHz clock for VGA synchronization.

Design Approach

1. Counters: Designed as ripple carry adders with a decimal system to manage scorekeeping on the seven-segment display.
2. Game Logic:
   • Player and obstacle positions defined within the 640x480 VGA bounds.
   • Jump physics implemented using registers and bit-shifting for realistic motion.
   • Collision detection compares player and obstacle coordinates.
3. VGA Display:
   • Static elements: Floor and "Game Over" screen.
   • Dynamic elements: Player and obstacles with moving coordinates.

Gameplay Mechanics

• Starting Position: Player starts at x=40, y=460, with the floor at y=460.
• Obstacle Generation: Randomly appears at x=640 with varying heights.
• Game Over: Collision detection runs at 10Hz. If collision occurs, the display shows "DED," and the game stops until reset.

Hardware Utilization

• DE10-Lite Features Used:
  • 7-segment displays for scorekeeping.
  • Buttons and switches for game control.
  • Internal clocks for timing mechanisms.
  • VGA output for game visuals.
