Animation of an object using other object's fcurves
There a few things going on in this that I’m slowly understanding and/or I find interesting and useful.
This example comes from leasons in Animation section on Interpolations Example 3.3a.
1. I’m getting used to the idea of using the Group Subprogram to develop reuseable programs.
– in this case the Group Subprogram creates the node (Invoke Subprogram – animate-to-Fcurve) which could not be used for other objects as well as this one here.
2. In the example, they are using Curve Interpolation to control the motion behaviour of the animated object, but it seems wiser to use the interpolation from FCurve (any FCurve will do – I just used the one from the circle below running on the x axis.) Wiser, becasue it’s easy to manipulate the curve with all it’s handles and a clear grid than to use the simple curve and dots in the Curve Interpulation window.
