301B: Airspace Transitions

"In a commercial flight, you don't instantly teleport from London to New York. There is a transition phase where systems prepare for the new arrival. If your AI is using `SceneManager.LoadScene`, the entire 'engine' of your game freezes while the new world loads. A skilled Navigator audits for **Async Transitions** to keep the cockpit responsive."

The Concept: LoadSceneAsync

As detailed in **Chapter 8**, Unity allows you to load scenes in the background. This prevents the "Not Responding" window and allows you to display a loading bar or transition animation to the player while the heavy lifting happens behind the scenes.

The Navigator's Strategy:
* **SceneManager.LoadSceneAsync:** Starts the load process on a separate thread.
* **AsyncOperation.progress:** A value from 0 to 1 that you can use to drive a loading bar.
* **allowSceneActivation:** A toggle that lets you wait for a user's input before actually "jumping" into the new scene.

The AI Trap: "The Synchronous Jump"

You ask the AI: "Load the next level when I walk into the portal."

// AI-Generated Code: The System Hiccup
public void EnterPortal() {
    // Audit Fail: The game will freeze until "Level2" is finished loading!
    SceneManager.LoadScene("Level2"); 
}

This is "Blocking I/O." During a large scene load, Unity cannot process input, play music, or update animations. It feels like a crash to the user. A professional Navigator uses a Coroutine or Async task to keep the "Loading Screen" active and fluid.

Corrective Protocol

IEnumerator LoadNewScene(string sceneName) {
    AsyncOperation op = SceneManager.LoadSceneAsync(sceneName);

    while (!op.isDone) {
        float progress = Mathf.Clamp01(op.progress / 0.9f);
        loadingBar.value = progress; // Update UI
        yield return null; // Wait for next frame
    }
}
