Hello @Dave ,

Welcome to the Plugin Café forum and the Cinema 4D development community, it is great to have you with us!

Getting Started

Before creating your next postings, we would recommend making yourself accustomed with our Forum and Support Guidelines, as they line out details about the Maxon SDK Group support procedures. Of special importance are:

Support Procedures: Scope of Support: Lines out the things we will do and what we will not do. Support Procedures: Confidential Data: Most questions should be accompanied by code but code cannot always be shared publicly. This section explains how to share code confidentially with Maxon. Forum Structure and Features: Lines out how the forum works. Structure of a Question: Lines out how to ask a good technical question. It is not mandatory to follow this exactly, but you should follow the idea of keeping things short and mentioning your primary question in a clear manner. About your First Question

Your question is effectively out of scope of support because we do not debug code for users as lined out in our support guidelines. So, you cannot just post your code and then ask us to fix it, this especially applies when things like Chat GPT are involved.

With that being said, there are two (three) major problems with your code:

show_script_list_dialog: This is pure nonsense regarding creating and running a dialog. Dialogs must be implemented, see here for our dialog examples. run_script: This does not set the runtime environment, the globals, of the script to run. Which will cause many scripts to fail, as script manager scripts are prepopulated with doc and op. Plugin ID: The plugin ID 1009792 you are using does not seem to be a valid ID, the current plugin ID counter is at 1062027. You can do whatever you want to do locally, but you cannot ship any plugins with such made up IDs.

You also do not really need a full-blown dialog here, you could just get away with ShowPopupDialog. Find a simple version below. Please understand that we cannot support ChatGPT nonsense output in future postings of yours.

Cheers,
Ferdinand

Result:
Running the twice hello_doc.py script with the wrapper script run_scripts.py. And then for the lulz run the wrapper with the wrapper to run the hello_doc script.
