After playing with several extensions to get a better overview what is possible to extend. I figured out that some options are missing with the parameter tab.
By the way the documentation in wiki is not good, to get an idea. (sorry to say that)
I don’t know where comes that, properly is this extension (there are also some more) which is never be updated/patched over time.
These options brings in the moment “choose an option”
example: File selection and variable selection (from GDevelop-extensions/JSONResourceLoader.json at main · GDevelopApp/GDevelop-extensions · GitHub)
see “Choose an option”
Event Editor
Possible Selections:
So my question, it is not possible anymore to choose files or select a variable from my scene?
Finally I found also a lot of ways to come to the result that I would like to achieve.
But this missing selection makes for me no sense. So if it should be not possible in the Editor, then the extensions should be deprecated or removed from the extension selection.
