Automate Chrome Dino Game using Python

Automate Chrome Dino Game using Python

Automating the Chrome Dino Game (also known as the T-Rex game) using Python can be a fun and educational project. This game appears in Google Chrome when you're not connected to the internet. Automating it typically involves simulating key presses based on the game's visuals.

To automate the game, you can use Python libraries like pyautogui for controlling the keyboard and PIL (Pillow) or opencv-python for capturing and processing the screen content. Here's a high-level overview of the steps involved:

Step 1: Install Necessary Libraries

First, install the required libraries:

pip install pyautogui pillow opencv-python

Step 2: Capture Game Screen

You need to capture the screen area where the game is running. You can use Pillow for taking screenshots and OpenCV for image processing.

Step 3: Detect Obstacles

Use image processing techniques to detect obstacles. This could be as simple as detecting changes in pixel values in the region where obstacles appear.

Step 4: Simulate Keypresses

Use pyautogui to simulate key presses (like the space bar for jump) when an obstacle is detected.

Example Code

Here's a very simplified example to give you an idea:

import pyautogui import time from PIL import ImageGrab import cv2 import numpy as np def detect_obstacle(start_x, end_x, start_y, end_y): # Grab a region of the screen where obstacles appear screen = np.array(ImageGrab.grab(bbox=(start_x, start_y, end_x, end_y))) screen = cv2.cvtColor(screen, cv2.COLOR_BGR2GRAY) # Convert to grayscale # Detect changes or obstacles in the region # (this is a simple example; you may need a more sophisticated approach) if np.any(screen < 127): # Assuming obstacles are darker pixels return True return False # Coordinates of the region to monitor (you need to adjust these) REGION_X_START = 300 REGION_X_END = 600 REGION_Y_START = 300 REGION_Y_END = 400 # Wait for 5 seconds before starting (to switch to the game window) print("Starting in 5 seconds...") time.sleep(5) try: while True: if detect_obstacle(REGION_X_START, REGION_X_END, REGION_Y_START, REGION_Y_END): pyautogui.press('space') # Jump time.sleep(0.05) # Check every 50 milliseconds except KeyboardInterrupt: print("\nStopped")

How It Works

  • The detect_obstacle function captures a region of the screen and checks for the presence of obstacles.
  • The script continuously checks for obstacles and presses the space bar when one is detected.
  • You need to manually set the coordinates for the region to monitor. These coordinates depend on your screen size and the position of the game window.

Important Considerations

  1. Screen Coordinates: You need to adjust the screen coordinates in the script (REGION_X_START, REGION_X_END, REGION_Y_START, REGION_Y_END) to match the area where the game is displayed on your screen.
  2. Game Speed: As the game progresses, it gets faster. Your script might need to account for this by reducing the sleep interval or adjusting the detection algorithm.
  3. Complexity: This is a basic example. The actual game might require more sophisticated image processing to reliably detect obstacles, especially as the game speeds up and night mode kicks in.
  4. Fair Play: Remember, automating games like this is just for fun and learning. It should not be used to falsely achieve high scores or compete with others.
