Here are some other possible options to implement "camera interaction" or demonstrate real-time rendering in a 2D cutscene:
1. Slight Parallax or Background Shift
- Shift the background or elements in the scene slightly in response to user input (e.g., arrow keys or mouse movement).
- This creates a subtle but effective indication of interactivity, mimicking camera movement in a way that works for 2D.
2. Scaling or Layer Movement
- Add a zoom-in or zoom-out effect triggered by a key press, or slightly move a foreground or background layer to create a parallax effect.
- This interaction stays non-intrusive while demonstrating real-time rendering.
3. Transparency Toggles
- Allow the player to make specific sprites or layers transparent or toggle their visibility by pressing a key.
- This method provides an obvious but simple cue of interactivity.
4. Dynamic Scene Adjustments
- Enable small changes to the scene, such as turning an effect (e.g., glow or lighting) on or off, or repositioning an object slightly with a key press.
- These adjustments confirm real-time rendering while allowing the cinematic experience to remain uninterrupted.
Parallax Backgrounds
- If the style allows, you can include parallax backgrounds to create a sense of depth. However, this may not fit every cutscene.
And of course any other option you can think of to proof it is real-time rendered and not pre-rendered.
