Description

Make a field for editing an AnimationCurve.

Curve field in an Editor Window.

// Makes the selected GameObject follow the animation curve.
//
// Usage: Generate the curves for X,Y and Z axis of your desired GameObject
// Select an Object and click Generate Curve.
// Press Play and see your object moving.

And the script attached to this editor script:

// FollowAnimationCurve.js
// This script has to go outside of the Editor Folder.
