LytoColorHack

LytoColorHack is a simple project for fun.

Use it to automatically play Lyto Different Color Game to beat your pitty friends. :D

Demonstration

Click the above thumbnail to see demo video on Youtube.

Test Environment

This code was developed and tested on the following environment.

• Windows 10 :: 64-bit
• Python 3.6.1 :: Anaconda 4.4.0 (64-bit)
• Resolution :: 1920 x 1080

The accuracy of cv2.HoughCircles() heavily depends on the screen resolution and the parameters. Please feel free to tune the parameters to attain higher accuracy of circles detection.

Dependencies

Python package required for this project can be easily installed via pip:

pip install numpy
pip install opencv-python
pip install pillow
pip install pyautogui

For Linux system, PIL (pillow) does not support ImageGrab. Use alternative library:

pip install pyscreenshot

Usage

Open the game and place the browser on the left to fill the left half screen as the demo video shows.

python LytoColorHack.py

Execute the code, a window will pop up and show the target region on screen and the circles it detected.

Once the game is started, press s to tell the program the game had started and begin auto-gaming.

To exit the program and close the window, press ESC.

Methodology

• Take a screenshot of the left half screen.
• Indentify the circles in the screenshot using Hough in OpenCV.
• Post-process circles:
  1. Boundary check
  2. Non-max suppression
• Identify the circle with the most different color from the others.
• If auto-gaming is on, simulate mouse to click the circle we identified.
• Display the result on a separate window.
