add_text_animation
Apply entrance, exit, or looping animations to text segments in video editing projects. Choose from effects like typewriter, spring, glitch, fade-in, or fade-out to enhance visual storytelling.
Instructions
为文本片段添加动画效果
Args: text_segment_id: 文本片段ID，通过add_text_segment获得 animation_type: 动画类型，支持以下类型： - "TextIntro": 入场动画 - "TextOutro": 出场动画 - "TextLoopAnim": 循环动画 animation_name: 动画名称，如 "复古打字机", "弹簧", "色差故障", "淡入", "淡出" 等，可以使用find_effects_by_type工具，资源类型选择TextIntro、TextOutro、TextLoopAnim，从而获取动画类型有哪些 duration: 动画持续时间（可选），格式如 "1s", "500ms"

Implementation Reference
- jianyingdraft/tool/text_tool.py:138-231 (handler)The primary handler for the 'add_text_animation' MCP tool. It performs input validation (animation type and existence check using JianYingResourceManager), resolves draft/track info via index_manager, and delegates to the service layer for execution.
