Hello,
I’m trying to get VSCode to attach to unreals python instance, but im getting weird behaviour from unreal when im trying to start the listen server.
I did all the necessary things to setup python for unreal (I can execute python scripts from within unreal perfectly fine).
However when I try to execute this script below, a new instance of Unreal starts. So I suddenly have two editors and after a moment the output log in the original editor screams in pain and I get this output below the script.
I have no clue why unreal starts a new instance tho. It is a mystery.
However what I do know is that I can open up a listen server that I can actually connect to with the package called ptvsd. Which is also used for debugging python but it’s deprecated and even recommends using the microsoft version debugpy
I did install both packages for the python interpreter that is shipped with the unreal engine version I am using.
Executing the script with the debugpy version outside of unreal works, but that’s not what I need.
init_remote_debug.py
def attach_to_debugger(host, port):
try:
import debugpy
debugpy.listen((host, port))
debugpy.wait_for_client()
print("VSCode Remote Debug enabled on %s:%s." % (host,port))
except:
import traceback
traceback.print_exc()
attach_to_debugger("0.0.0.0", 60058)
Output Log
