Python MediaPipe Pose x, y variables equal to certain points of the character and the character will repeat those movements that the camera sees

Great work thank you for documenting this, the official docs are a bit lacking here. They give you a clue that it can be done but don't say HOW!

How about a video on getting and setting blueprint default properties? It works fine but I am running in to a problem with type conversion

[TheFeanture]

Thank you so much! It is super helpful. Before this video I used Format Text with {0} {1} to get input and had no output. Lol) Thank you!

hey, this is code to import only if its not imported :P (maybe somone needs that)

import sys
sys.path.append(r"path to folder")

if "tutorial" in sys.modules:
import tutorial
import importlib
importlib.reload(tutorial)
else:
import tutorial

Thanks Matt. Any thoughts on accessing EditorUtilityWidget variables from Python?

[TrashPraxis]

can I return an object reference, for example from a 'create asset' operation?

awesome tutorial!how to package a python file with a build and then call it?right now you are using absolute path so it wouldn't work on a different computer right?

Is there any way to output other data type than string ?
Thank you !

Hi Matt,
Thanks a lot for your videos. I was wondering whether it works to add a python script which streams some data from a sensor which I could use then to move an actor in the editor? I wonder whether it stops the script every time with the new tick and reruns it or whether it shifts back and forth from other tasks to the script? I would like to make the actor move with the real time data transferred. Any ideas, if that works?

I read before python is not available on run time, but meaning it should work with the editor using ticks, right? I also read about multi threading. Any Tipps on that using blueprints or python?

Thank you for your inputs!

How would you use this to enter text from a textbox input into your script?

Hi Matt! Do you know any way to set/get state from the game runtime with python? More specifically, Is there a way to make an api for a game that you can call from python? Thank you!

[edoartworks]

Alright Matt! This is really useful! Nice one :)

[BrunoSommier]

thanks for your helpfull tutorial.
NEWBIE QUESTION :In my python script I have a return in a function to return value that is use in another function. but when the return is call, is exiting the script to the output,
is it possible to have 2 type of return, one internal that give back the variable I need and one for the output message to print string ?
hope it's clear
