Local projects and communication

[robotasun]

Is it possible to run local projects in the Scratch app, without User/Password information or a sessionId?
I'm working with external hardware, and communication to it will be through a Python script that mustn't be tampered with, and preferably takes no inputs. It is also okay if the Scratch project receives nothing from the Python script, i.e. I just want to read some variables from Scratch.

From PyPI:
Get a Scratch cloud var from the clouddata logs:
Does not require a connection / session.

value = scratch3.get_var("project_id", "variable")
variables = scratch3.get_cloud("project_id") #Returns a dict with all cloud var values

Is project_id in this case something that is reached online, or could a local project be accessed with its own ID number?
Would such an ID number be constant?
Is it possible to sniff current project_ID values of Scratch projects running on the machine?

Finally, is it possible to run the following line with something like localhost instead?

conn = scratch3.TwCloudConnection(project_id = "project_id", username="username", cloud_host="<wss://clouddata.turbowarp.org")

[TimMcCool]

value = scratch3.get_var("project_id", "variable")
variables = scratch3.get_cloud("project_id") #Returns a dict with all cloud var values

These functions will send / get data from Scratch's cloud variable server.

Is project_id in this case something that is reached online

Yes. It's the id that the project has on the Scratch website (scratch.mit.edu/projects/project_id/)

or could a local project be accessed with its own ID number

No, and cloud variables don't work on local projects anyways, they only work on projects posted on the Scratch website.

Finally, is it possible to run the following line with something like localhost instead?

conn = scratch3.TwCloudConnection(project_id = "project_id", username="username", cloud_host="wss://clouddata.turbowarp.org")

Yes, it's technically possible (if you manage it to host a websocket server on your computer and then open the project on turbowarp with the URL of the locally hosted websocket as cloud host: https://docs.turbowarp.org/url-parameters#cloud_host)
