A bunch of scripts for better orbit arrangement in Unity
Assets->Import Package->Custom Package, then choose the package downloaded from release.
After importing the package, there should be three more folders in your project. Get into the folder BeizerTool. Drag the script BezierDriver.cs onto the object(s) you want to control.
Select the object in Hierarchy. There are three control points in the Scene by default. You can drag the handle to adjust the orbit which is drawn with white dash. To add more control points, input the number of control points you need in the field named size under Ctrl Points in Inpector.
Click on Play. Check the orbit of objects.
