nice links. never thought of it. might work. yes xml will be a bitch.
No, storyboard would be easy. Im talking prototyping entire dialog inside sketchup. no camera movement just dialog.
dialog tree is xml file of entire dialog with certain character. like when you play adventure game you click on character, then he says hello massage and you are offered couple possible questions, when you click on them he gives you answer where you get new questions or your just brought back to first screen. so all of that in one file is called dialog tree. its mostly in xml and in modern games like starcraft 2 or dragon age or neverwinter nights its done in scripting language like ruby or lua.
thanks for advice, I tried scripting so Im not master programmer but I really need to do this. Ill post my progress...
