301E: Regional Buffers

Pilot Record
Student Profile
"In a Digital Twin of a city, you don't unload the entire street just to look inside a single Smart Building. You 'layer' the building's data on top of the street. If your AI is forcing a full scene swap for every small location, you've created **Environmental Drag**. A skilled Navigator audits for **Additive Loading**."

The Concept: Additive Scenes

As detailed in **Chapter 8**, Unity allows multiple scenes to be open at once. This is critical for **Smart Buildings** where the structural shell remains constant, but interior data or GIS layers are loaded dynamically as needed.

The Streaming Advantage:
* **Seamless Transitions:** The player/pilot never sees a loading screen because the new area loads in the background.
* **Memory Efficiency:** Only the current "Region" is in memory, rather than the entire flight plan.
* **Modular Architecture:** Keep the "Skybox" and "Global Managers" in one scene, and stream the "Terrain" in others.

The AI Trap: "The Memory Flush"

You ask the AI: "Load the interior of the building when the player touches the door."

// AI-Generated Code: Standard (Single) Loading
public void EnterBuilding() {
    // Audit Fail: This destroys the exterior world!
    // The player will see a jarring 'jump' to a black screen.
    SceneManager.LoadScene("BuildingInterior"); 
}

This is "Logic Amnesia." In architecture and GIS projects, maintaining context is vital. If the user zooms into a building, they expect to still see the surrounding terrain. Standard loading flushes that data, forcing a slow re-load later.

Elite Telemetry

Research shows "Elite" teams achieve 15% faster lead times by keeping AI on a "very tight leash."

  • Small Batches Solving one problem at a time prevents logic drift.
  • Modular Design Localizing the "blast radius" of AI changes.
  • Tight Loops Rapid iteration with constant code review.

The Pilot's Correction

Corrective Protocol
using UnityEngine.SceneManagement;

public void EnterBuilding() {
    // Corrected: Layering the interior on top of the world
    SceneManager.LoadScene("BuildingInterior", LoadSceneMode.Additive);
}
