Passing additional arguments when launching an executable

Unity Engine

Hi,
I am trying to use the additional_args parameter when instantiating a UnityEnvironment() but it doesn’t look like I am receiving that parameter in the environment.

In Python:

additional_args = []
additional_args += ["--test_arg"]
env = UnityEnvironment(..., additional_args=additional_args)

In Unity (3DBall scenario, inside Ball3DAgent.Initialize())

var sr = File.CreateText(fileName);
string[] args = System.Environment.GetCommandLineArgs();
for (var i = 0; i < args.Length - 1; i++)
{
      sr.WriteLine(args[i]);       
}
sr.Close();

As you can see, I am generating a text file with all the received arguments, but so far I only see the path to the executable and --mlagents-port 5005

Any ideas what could be happening?

Hi,

There is a bug in the code you are using to retrieve the arguments:
Replace
for (var i = 0; i < args.Length - 1; i++)
with
for (var i = 0; i < args.Length; i++)
Let us know if there is still an issue.

Oh wow, how did I miss that. Thanks!
