This GitHub Action allows you to automate the process of building a Unity project for the Windows 64-bit platform using a self-hosted runner. It facilitates the build process, ensuring that the necessary steps are executed smoothly.

• unityPath (required): The full path to the Unity executable.
• buildPath (required): The path where the build artifacts will be stored.
• executeMethod (required): The name of the Unity method to execute during the build.
• extraArgument (required): Extra arguments to pass to the Unity build command.
• projectPath (optional): The path to the Unity project. Default is the root of the repository.
• exeFileName (required): The name of the .exe file to check for in the build folder.

This action runs using a composite run strategy, ensuring efficient execution of the defined steps.

1. Check if Build Folder Exists: Verifies if the build folder already exists.
2. Remove Existing Build Folder: Removes the existing build folder if it exists.
3. Create Build Folder: Creates a new build folder.
4. Unity Build: Executes the Unity build process based on the provided inputs.
5. Check for Custom .exe File: Verifies if the custom .exe file exists in the build folder.
