Bézier Path Creator [Unity Engine]
An intuitive and lightweight editor for quickly creating smooth paths in the editor.
You can easily make objects move along these paths, or use them as a guide for spawning objects and generating meshes.
Paths can be rotated and scaled, and work well in both 2D and 3D space. Paths can also be created entirely from code -- just provide an array of waypoints and get a smooth path back.
Full C# source code is provided, so you can extend the tool to meet your specific needs if necessary.
