203F: The Custom Gauge

Pilot Record
Student Profile
"Standard buttons are fine, but a pilot needs an Altimeter or a Radar. Creating 100 separate "Image" objects for a radar grid is inefficient. A Pilot creates a custom `VisualElement` that draws itself."

The Concept: Custom Controls

You can create your own UI tags (e.g., ``).

* **generateVisualContent:** A function where you draw lines/circles directly to the mesh.
* **Performance:** Draws the entire radar in 1 batch, rather than 100 Image GameObjects.

The AI Trap: "The Prefab Spawner"

You ask the AI: "Make a radar grid with 50 lines."

// AI-Generated Code: Object Spam
void Start() {
    for(int i=0; i<50; i++) {
        Instantiate(linePrefab, uiParent);
    }
}

This is "Hierarchy Pollution." It creates a massive list of objects that slows down the UI layout engine.

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: Single Draw
void GenerateVisualContent(MeshGenerationContext mgc) {
    var painter = mgc.painter2D;
    painter.MoveTo(start);
    painter.LineTo(end);
    painter.Stroke();
}
Your Pilot Command
> A skilled Pilot directs the AI to use the Mesh API. You command: "Create a custom RadarElement and override GenerateVisualContent to draw the lines using the MeshGenerationContext."
