TimelineFloatArrayKeyframe

A keyframe that stores an array of floating-point values for timeline animations.

Used by TimelineFloatArrayTrack to animate multiple numeric values simultaneously. Each element in the array is interpolated independently, allowing complex multi-value animations with a single track.

Common uses:

• Animating multi-dimensional positions (2D/3D coordinates)
• Color components as separate values (R, G, B, A)
• Complex shape morphing (vertex positions)
• Particle system parameters
• Any property that requires multiple synchronized values

Example usage in a timeline:

var track = new TimelineFloatArrayTrack();

// Animate a 2D position
track.add(new TimelineFloatArrayKeyframe([0, 0], 0, LINEAR));
track.add(new TimelineFloatArrayKeyframe([100, 50], 30, EASE_IN_OUT));
track.add(new TimelineFloatArrayKeyframe([200, 0], 60, BOUNCE_EASE_OUT));

// Or animate RGBA values
track.add(new TimelineFloatArrayKeyframe([1.0, 0.0, 0.0, 1.0], 0, LINEAR));
track.add(new TimelineFloatArrayKeyframe([0.0, 1.0, 0.0, 0.5], 30, EASE_OUT));

Note: All keyframes in a track should have arrays of the same length.

The array of float values stored in this keyframe. Each element is interpolated independently during animation. All arrays in a track should have the same length.
