Ease Sliders for EffectCraft

A three-slider easing panel for EffectCraft, inspired by the Ease Sliders in Mt. Mograph's Motion v2: drag Out to ease the leaving side of the selected keyframes, In for the arriving side, Both for the two together. A side at 0 % is plain linear; at 100 % it comes to (or leaves from) full rest. Dragging previews live; each drag is one undo step.

适用于 EffectCraft 的三滑杆缓动面板（灵感来自 Motion v2 的 Ease Sliders）：选中关键帧后拖 Out（出场缓动）、In（入场缓动）、Both（两边联动）；0 % = 线性，100 % = 完全停顿；拖动实时生效，一条拖动 = 一个撤销步骤。

Two panels / 两个面板：

• Ease Sliders.jsx — three-slider easing (Out / Both / In), as described below
• AutoSway.jsx — two modes, picked from the selection. Pin mode: select one layer with Puppet pins (pin root → tip) and click Sway — it rigs every pin with a null (via EffectCraft's built-in paths.pointsFollowNulls), parents the nulls into a chain and writes a lagged sine to each rotation, so the wave travels root → tip and the mesh bends. Layer mode: select a parented chain and the same sway goes onto every rotation. Both read four sliders (Wind Amount / Direction / Speed, Lag) from a [SwayControl] null live — adjust it anytime. Stop clears everything. 2D for now / 图钉模式：选中带 Puppet 图钉的图层（从根到尖顺序打钉）点 Sway——用内置 paths.pointsFollowNulls 给每个图钉配一个空对象并串成链，逐级滞后正弦驱动，波浪从根传到尖；图层模式：选中父子链直接摆。参数都在 [SwayControl] 控制层滑杆上（风力量/风向/速度/滞后），实时生效；Stop 清除

Install / 安装

Requires EffectCraft v0.8.0 or later / 需要 EffectCraft v0.8.0 及以上。

• In EffectCraft: File ▸ Scripts ▸ Install ScriptUI Panel… and pick Ease Sliders.jsx
• Or copy it to Scripts/ScriptUI Panels/ in the settings folder:
  • Linux: ~/.config/effectcraft/Scripts/ScriptUI Panels/
  • macOS: ~/Library/Application Support/EffectCraft/Scripts/ScriptUI Panels/
  • Windows: %APPDATA%\EffectCraft\Scripts\ScriptUI Panels\
• Or / 中文：把文件放进上面的目录（或用菜单安装），然后 Window ▸ Ease Sliders.jsx

Use / 使用

1. Select keyframes in the timeline / 在时间轴选中关键帧
2. Open Window ▸ Ease Sliders.jsx / 打开面板
3. Drag a slider / 拖滑杆：Out = leaving side, In = arriving side, Both = together

Hold keys and values that don't interpolate are left alone; a side dragged to 0 % goes back to linear interpolation.

Hold 关键帧和不可插值的属性不动；某一侧拖回 0 % 即恢复线性。

Notes

• Independent, unofficial. Not affiliated with Mt. Mograph or the EffectCraft project; no Motion v2 code is used — the panel is written against EffectCraft's documented After Effects-style scripting API.
• Uses only setTemporalEaseAtKey / KeyframeEase / setInterpolationTypeAtKey (speed 0, influence 0–100), the same model as EffectCraft's bundled Ease Presets panel.
