@ue-too/animate / index / RGBAnimationHelper

クラス: RGBAnimationHelper

定義: animatable-attribute.ts:299

Interface for type-specific interpolation helpers.

Remarks

Animation helpers provide the lerp (linear interpolation) logic for specific types. Different types require different interpolation strategies:

• Numbers: Simple linear interpolation
• Points: Component-wise interpolation
• Colors (RGB): Component-wise color interpolation
• Strings: Step-based (threshold) interpolation

例

const myHelper: AnimatableAttributeHelper<number> = {
  lerp: (ratio, start, end) => {
    const t = (ratio - start.percentage) / (end.percentage - start.percentage);
    return start.value + t * (end.value - start.value);
  }
};
