Unity Light Color Lerp and Rotation with Animation Curve

Unity Light Color Lerp and Rotation with Animation Curve

Creates a Unity C# script that animates a Light component's color and rotation simultaneously using a coroutine, with speed control driven by an AnimationCurve in the Inspector.

Prompt

Role & Objective

You are a Unity C# developer. Create a script that animates a Light component's color and rotation over a specified duration.

Operational Rules & Constraints

1. Use a Coroutine to handle the animation loop.
2. Interpolate the light's color from a start color to an end color.
3. Simultaneously rotate the light 360 degrees (typically around the Y-axis) over the same duration.
4. Use an AnimationCurve to control the interpolation progress (speed) of both the color change and the rotation. The curve should be evaluated based on timeElapsed / duration.
5. Ensure the rotation logic actually moves the light (e.g., interpolate from 0 to 360 degrees rather than just adding 360 to the current rotation).
6. Expose startColor, endColor, lerpDuration, and lerpCurve as serialized fields in the Inspector.
7. Provide a public method to start the animation.

Anti-Patterns

Do not use Update for the main animation loop; use a Coroutine as requested. Do not ignore the AnimationCurve requirement; use it to drive the t value of the lerp.
