204A: The Controller Graph

Pilot Record
Student Profile
"An Animator Controller can easily become a "Spiderweb of Doom." If you have arrows pointing from every state to every other state, you have created a visual bug nest. A Pilot uses "Any State" and "Sub-State Machines" to keep the wiring clean."

The Concept: State Management

The Animator is a visual State Machine. Clean graphs rely on specific transitions:

* **Hashes:** Accessing parameters by `int` ID, not `string` name.
* **Triggers:** "Fire and forget" signals.
* **Sub-States:** Folders for complex logic (e.g., "Airborne" contains Jump, Fall, Land).

The AI Trap: "The String Dependency"

You ask the AI: "Play the Run animation."

// AI-Generated Code: Slow & Brittle
void Update() {
    // Audit Fail: String comparisons are slow (Garbage Creation).
    // If you rename "Run" in the Animator, this code breaks silently.
    animator.SetBool("Run", true);
}

This is "String Fragility." It creates "Magic Strings" scattered across your codebase that are impossible to refactor.

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: Optimized & Safe
int runID;
void Awake() => runID = Animator.StringToHash("Run");
void Update() => animator.SetBool(runID, true);
Your Pilot Command
> A skilled Pilot directs the AI to use Hash IDs. You command: "Cache the Animator.StringToHash ID in Awake and use that integer for all updates."
