201F: Animation States
"A pilot doesn't just pull the stick; the plane's flaps, rudder, and lights all react in sync. If your AI sets an animation to "Run" but the code says "Idle", you have a visual disconnect. A skilled Architect audits for Animator Parameters."
The Concept: Animator Controller
The **Animator** is a State Machine for visuals. We drive it using Parameters (Bool, Float, Trigger).
* **Transitions:** The lines connecting animations (e.g., Idle -> Run).
* **HasExitTime:** Should the animation finish before switching? (Uncheck for instant response).
* **Blend Trees:** Smoothly mixing animations (Walk -> Run) based on speed.

Red Flag Detected
The AI Trap: "The String Trigger"
You ask the AI: "Play the 'Run' animation."
// AI-Generated Code: Brittle and Jerky
void Update() {
// Audit Fail: Strings are prone to typos.
// Play() forces a snap transition, looking unnatural.
if (speed > 0.1f) {
animator.Play("Run");
}
}
This is "Hard State Switching." It overrides the transition logic you built in the Animator window, causing the character to "pop" between poses.
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: Smooth Driving
void Update() {
// We just update the data. The Animator handles the visuals.
bool isRunning = agent.velocity.magnitude > 0.1f;
animator.SetBool("IsRunning", isRunning);
}
Your Pilot Command
> A skilled Architect directs the AI to use Parameters. You command: "Use SetBool to drive the 'IsRunning' parameter, allowing the Animator to handle the smooth transition."
