How easy is it to modify properties of an entity with the DOS2 editor?
I'm not sure which properties you meant exactly in your question. There are a lot of things you can change in the object properties panel for a given object. They can have several scripts associated with themselves. If you click in the script, you then get a list of script variables that you can change right from the editor. I think this is how the majority of object properties get changed.
If you mean re-writing character and item scripts to behave differently, then I haven't done as much with that.
I'll give you one example of what I am talking about. In our mod, we have a cemetery with gravestones. When you click on them in game, you get text displayed on the gravestone. In order to do this, there is a script associated with the object called "DisplayTextOnCharacter". When I click on the script within a window pane, it brings up arguments to the script, one of which is "DialogKey". You fill it in with the filename of the dialog you want to display when the character clicks on it. There was no searching for the script and manually editing it. Everything is done by point and click through the object properties.
Thank you for posting. Did Larian tell you around when they were planning on releasing tutorials or documentation?
I don't have any dates on that, sorry.
