Narrative scripting languages like Yarn Spinner or Inkle were originally meant for writing dialogue, but I think they can also be used for scripting the world progression even when no dialogue or even narration is involved.
Example for something silent that can be scripted with a narrative scripting language:
- When the player pulls a lever...
- Move the camera to show a certain gate
- Open the gate
- Move the camera to show something interesting behind the gate
- Return the camera to the player
Even though no text nor voice are involved here, I think a narrative language will still fit better than a traditional scripting language because:
- Narrative languages describe everything in steps. Scripting languages will need to work a bit harder to generate steps the actual game engine can use.
- Narrative languages have visual editor that can help showing the flow of the level as nodes.
- The interface between a narrative language and the game engine tends to be seems to tend to be higher level (and less powerful) than the one with a traditional scripting language.
On the other hand, flow control seems a bit more crude and ugly with narrative scripting languages than with traditional scripting languages. It should probably still be fine for simple things (e.g. - player activates a keyhole. Do they have the key?), but I wonder if a game can reach a point where it becomes too complex for a narrative language (I'm still talking about simple world progression, not full blown modding)
