I have doubts with the documentation and I don't understand it very well when it comes to assigning integrated functions. Can I put live functions created within the create script of a particular object?

Greetings and thanks in advance.

live_name is intended for enabling live-reload in non-top-level functions. This does allow you to live-code functions in Create events (by using live_call + live_name) inside them, but does not currently work for constructor functions as they cannot be adequately simulated through current GML
