Is there any way to pass arguments to the game when running it from the CLI with Headless/Server version?

You can use OS.get_cmdline_args() for this. However, you’ll have to parse command-line arguments yourself. Due to how Godot currently parses them, there are a few limitations to be aware of:

  • Command-line arguments should be written in the form --key=value. Godot will try to open value as if it was a scene file if you use --key value.
  • Custom command-line arguments shouldn’t conflict with engine arguments.

If this is too limiting, you can also use environment variables using OS.get_environment() instead.

PS: You can set Editor → Main Run Args in the Project Settings to define command-line arguments to be passed by the editor when running the project.

To parse command-line arguments into a dictionary, you could use something like this:

    var arguments = {}
    for argument in OS.get_cmdline_args():
        # Parse valid command-line arguments into a dictionary
        if argument.find("=") > -1:
            var key_value = argument.split("=")
            arguments[key_value[0].lstrip("--")] = key_value[1]

Is it possible to parse command line arguments with exported game binaries as well?

Can you give an example of how to work with
Editor → Main Run Args
?
