Returns the command line arguments passed to the engine.
Returns the command-line arguments passed to the engine.
Command-line arguments can be written in any form, including both [code]--key value[/code] and [code]--key=value[/code] forms so they can be properly parsed, as long as custom command-line arguments do not conflict with engine arguments.
You can also incorporate environment variables using the [method get_environment] method.
You can set [code]editor/main_run_args[/code] in the Project Settings to define command-line arguments to be passed by the editor when running the project.
Here's a minimal example on how to parse command-line arguments into a dictionary using the [code]--key=value[/code] form for arguments:
[codeblock]
var arguments = {}
for argument in OS.get_cmdline_args():
if argument.find("=") > -1:
var key_value = argument.split("=")
arguments[key_value[0].lstrip("--")] = key_value[1]
[/codeblock]
