refactor: use end state effect

[HardyNLee]

介绍

将 animationObject 中的 getEndFilterEffect 改为 getEndStateEffect，以便获得完整的终态 Effect
在 removeAnimationWithSetEffect 中，使用 getEndStateEffect 避免强行打断动画时，意外获取了当前态的位置，缩放，旋转，不透明度，模糊属性

Summary of Changes

Hello @HardyNLee, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refactors the animation system to ensure that the complete end state of an animation is accurately captured and applied, particularly when an animation is interrupted. By transitioning from a filter-specific state retrieval to a comprehensive end-state retrieval, the changes prevent visual inconsistencies and improve the reliability of animation handling.

Highlights

• Refactoring Animation State Retrieval: The method for retrieving the end state of an animation has been refactored from getEndFilterEffect to getEndStateEffect. This change signifies a shift from only capturing filter effects to capturing the complete final state of an animation, including transform properties like position, scale, rotation, and opacity.
• Improved Animation Interruption Handling: When an animation is forcibly interrupted (e.g., via removeAnimationWithSetEffect), the system now correctly applies the animation's intended end state. Previously, it might have inadvertently captured and applied the current, intermediate state's position, scale, rotation, opacity, and blur properties, leading to visual glitches. The getEndStateEffect now provides the comprehensive final state, ensuring a smooth transition.

Code Review

This pull request refactors animation handling to correctly capture the final state by replacing getEndFilterEffect with a more comprehensive getEndStateEffect. My review identifies a critical issue where getEndStateEffect is used without being defined, which would cause a runtime error. I've provided a suggested implementation. I also included a minor suggestion to improve code quality and maintainability in PixiController.ts.

[gemini-code-assist]

The getEndStateEffect function is missing. This function is intended to return the final state of the animation as an ITransform object. The code currently references this function but it's not defined, which will cause a runtime error.

Here's a suggested implementation to be placed before the return statement.

  function getEndStateEffect() {
    const endSegment = timeline[timeline.length - 1];
    const { duration, ease, ...transform } = endSegment;
    return transform;
  }
