Don't worry about it!

Have you read through the
scripting page? This is actually an introduction & breakdown of how scripting works in Visionaire Studio. It also gives a basic explanation of how to access / update data structure tables & fields.
I've mostly finished writing that page, save for the last few entries towards the end.
Quick note: The data structure page lists (almost all, but not every one of) the accessible data structure fields & tables. I've added some icons to each table row to indicate whether or not the field is scriptable; actually pretty much all fields are scriptable to some degree, even if it says they are not on the wiki page. The reason I say they are all scriptable is because they are to a degree, but some will not show any difference until after you reload the scene or character etc & some will not save the new values to the save game files, hence why they are not classed as scriptable.
Quick example: Let's say I want to change the action text (displayed text) of an object or character when I hover over it. I can do so by accessing & manipulating the language texts, but the changes will not be saved to the save game files, which means I have to create some conditions & queries to determine which name should be displayed on mouse over. Using that method I can now use previously unscriptable fields & have it remember my changes in save games, because values & conditions do get saved into the save game files.
I hope this post was informative & didn't bore you too much. It's just scripting side of things can be a little complicated & not everything is black & white in terms of what you can or can not do.
