extractcoordinates.jsx
This scripts allows you to export the current layer's positions through time to a .txt format (to export to a 3d app for instance)
It doesn't have a 'z' position nor does it allow you to select anchor points or rotation values - but I'll add it if needs be.
If no position keyframes are selected then all the position values during the comp length will be written to the text file
Code: Select all
// script created by mlk: mlkdesign@gmail.com Jan 2007
//
// The script will write to a text file the x & y values of the layer position for every frame comprised in
// a selection of keyframes, or for the whole comp duration if no keyframes are selected

Nice touch on the animating GIF too.
