Create Nulls From Paths EXTENDED在 AE 2018 中，Adobe 引入了使用表达式控制路径的可能性，与该版本一起出现的是由 Adobe 创建的 Create Nulls From Paths。
这是对 After Effects 的路径功能一个很好的补充，但缺少一些功能。这和Create Nulls From Paths师出同源，但它扩展了一些更多的功能。 除了对脚本的一些小改进外，添加的功能还有：从选定的创建路径、手柄控件、使用定位器，可以更精确控制路径，也可以方便制作贝塞尔曲线可视化。 该脚本适用于 AE 2018 及更高版本，由Thor Sarup添加了这些重大改进。
/*
Create Nulls From Paths.jsx v.0.5
Attach nulls to shape and mask vertices, and vice-versa.
Changes:
- wraps it all in an IIFE
- fixes call to missing method array.indexOf
*/
/*
Extended version by crunchycph.dk - youtube.com/c/crunchycphdk
Added features:
- Add controls for bezier handles
- Use locators instead of nulls
- Create path from nulls
- Uniform bezierepath
- Auto soft / round corners
- Close path
- Save settings
- Responsive interface
Possibly upcoming features:
- Parent nulls to shape layer
- Remove controls from path
- Option to create locator master style
*/
/*
Modified by Thor Sarup
- Ability to rotate / scale points (handles follow)
- locked rotation and scaling of handles (only for indicators)
- sets handles to shy
- renamed script to Path tools to save precious panel space :)
*/
/*
Update by crunchy 30. oct. 2017
- Fixed bug when both handle controls and use locators was selected for Create Path From Selected
- Renamed the plugin back to it's original, since it explains pretty well what this is doing. :)
- Researched the posibility to only connect selected verticies. But that is not posible since there is nothing like a selectedVerticies property
