FrostyFriend

FrostyFriend is a macOS-only automation helper for Whiteout Survival. It uses GoCV for computer vision and leverages AppleScript and Core Graphics for interacting with macOS applications.

Features

• Brings the target application to the foreground.
• Captures screenshots of the application's window.
• Performs multi-scale template matching.
• Simulates mouse clicks and movements.

Requirements

• macOS (this project is macOS-only)
• Go 1.16 or later
• GoCV

OS Dependencies

FrostyFriend uses macOS built-in tools:

• AppleScript for window control.
• The screencapture command for taking screenshots.
• Core Graphics (via the ApplicationServices framework) for simulating mouse events.

Installing OpenCV (for GoCV)

Install OpenCV and pkg-config via Homebrew:

brew install opencv pkg-config

Installing GoCV

Install GoCV using the following command:

go get -u -d gocv.io/x/gocv

Usage

To run the script, use the following command:

go run main.go [options]

Command-Line Options

• --iterations: Number of iterations to run the helper. Set to 0 for infinite iterations. (default: 0)
• --delay: Delay between iterations, in seconds. (default: 10)
• --random: If set, use a random delay between 0 and the specified delay.
• --debug: Enable debug mode to save screenshots annotated with rectangles and click points.
• --help: Display usage information.

Example Commands

Run with a fixed delay of 5 seconds between iterations and infinite runs:

go run main.go --delay 5

Run for 10 iterations with random delay up to 8 seconds between iterations:

go run main.go --iterations 10 --delay 8 --random

Run in debug mode to annotate and save screenshots:

go run main.go --debug

How It Works

1. Application Detection and Window Location: The script checks if "WhiteoutSurvival" is running and locates its window.
2. Screen Capture: It captures the game window to identify target images.
3. Image Detection and Interaction:
   • Searches for big_x.png. If found, it clicks on the location and waits for a brief delay.
   • Takes a new screenshot, searches for handshake_icon.png, and clicks on it if found.
4. Debug Mode: When enabled, the script saves annotated screenshots to help visualize the matched areas and click locations.
5. Logging: Logs significant events (e.g., image matches, clicks, errors) for easier tracking.

Dependencies

• GoCV: Handles image processing and template matching.
• AppleScript (osascript): Locates and interacts with the application window.
• cliclick: Performs the automated mouse clicks.

Important Notes

• The script currently only works on macOS due to its reliance on osascript and the screencapture command.
• Ensure the game window remains visible and unobstructed during the script's runtime to ensure proper functionality.
• Make sure the images used for template matching (big_x.png and handshake_icon.png) closely resemble the in-game visuals to ensure accurate detection.
