200B: Autopilot

Pilot Record
Student Profile
"A pilot doesn't memorize the location of every cloud; they use a navigation computer. If your AI is manually calculating rotation and movement vectors every frame to avoid obstacles, you are reinventing the wheel. A skilled Architect audits for NavMesh Agents."

The Concept: NavMesh Navigation

Unity's **NavMesh** system allows AI to "Walk" on defined surfaces, automatically avoiding walls and other agents.

* **Baking:** The process of pre-calculating the walkable floor.
* **NavMeshAgent:** The component that pilots the character.
* **SetDestination():** The only command you need to move the AI.

The AI Trap: "The Update Calculator"

You ask the AI: "Move the drone to the target while avoiding walls." 

// AI-Generated Code: Expensive Manual Math
void Update() {
    // Audit Fail: Raycasting every frame for walls?
    // Manual rotation math? This is brittle and heavy.
    transform.position = Vector3.MoveTowards(...);
    if (Physics.Raycast(...)) { Rotate(); }
}

This is "Calculation Drag." Writing your own physics avoidance is complex and error-prone. Why write 100 lines of buggy code when Unity has a built-in Autopilot?

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 Architect's Correction

Corrective Protocol
// Corrected: The "Set and Forget" method
using UnityEngine.AI;

public NavMeshAgent agent;

void Update() {
    // The internal computer handles ALL physics and turning.
    agent.SetDestination(target.position);
}
Your Pilot Command
> A skilled Architect directs the AI to use the NavMesh. You command: "Use a NavMeshAgent to handle pathfinding and obstacle avoidance."
