102A: The Component Audit
"A pilot doesn't guess if the landing gear is attached; they check the indicator light. If your code assumes a component exists without checking, you are flying blind. A skilled Engineer audits for Dependency Validation."
The Concept: RequireComponent
In Unity, scripts often rely on other components (like a Rigidbody or AudioSource) to function. If that component is missing, the game crashes.
* **[RequireComponent]:** A safety attribute that automatically adds the required dependencies when you add your script to an object.
* **TryGetComponent:** A safe way to check for a component without allocating garbage memory (unlike GetComponent).

The AI Trap: "The Silent Crash"
You ask the AI: "Write a script that plays a sound when the player jumps."
// AI-Generated Code: Fragile
public class PlayerJump : MonoBehaviour {
void Jump() {
// Audit Fail: What if there is no AudioSource?
// NullReferenceException: Object reference not set to an instance of an object
GetComponent<AudioSource>().Play();
}
}
This is "Dependency Rot." If a designer accidentally removes the AudioSource, the entire Jump mechanic breaks. A professional script enforces its requirements.
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
// Corrected: robust and self-healing
[RequireComponent(typeof(AudioSource))] // Automatically adds the component
public class PlayerJump : MonoBehaviour {
private AudioSource audioSource;
void Awake() {
// Safe to assume it exists because of the attribute above
audioSource = GetComponent<AudioSource>();
}
void Jump() {
audioSource.Play();
}
}
