Slide System

The Slide System allows presenters in a HoloMIT session to show and control a slide presentation on a virtual screen. This interaction is designed to be fully synchronized across all users in the session out-of-the-box.

Overview​

The core logic for the presentation is driven by the SlideController component. It abstracts the networking and input logic, allowing you to easily drop a presentation screen into any scene without having to write custom replication code.

Key Features​

  • Automatic Network Synchronization: Slide transitions are broadcasted automatically using NetworkTrigger components, ensuring all participants see the exact same slide simultaneously.
  • Input Ready: It integrates seamlessly with the Unity Input System via the HoloMITControls asset. It listens for specific actions to navigate (Next, Back, Start/Finish) without requiring custom input scripts.
  • Material-Based Rendering: Slides are simply an array of Texture2D images. The controller dynamically swaps the _MainTex property of the SlideMaterial applied to your virtual screen.

Setup Requirements​

To configure a working Slide System in your scene, add the SlideController to a GameObject and provide the following in the Unity Inspector:

  1. Slides Array: An ordered array of Texture2D images representing your presentation.
  2. Screen Object: A GameObject with a MeshRenderer that will act as the projection screen (e.g., a Quad or Plane).
important

Material Requirement The system requires a material named exactly SlideMaterial to be available in a Resources folder. The SlideController will instantiate it at runtime to prevent modifying your base asset, applying it to your Screen Object automatically.

Usage​

Once configured, the presentation can be driven by the user using the default bound input actions:

  • Start/Finish: Toggles the screen's visibility. Starting the presentation will always reset it to the first slide.
  • Next Slide: Advances the slide index (clamps at the last slide).
  • Back Slide: Decreases the slide index (clamps at the first slide).
