The question is as follows:
I need a script that can recognize objects excluded manually. That is,
the action of a button is to create 3 spheres: (sphere1, sphere2,
sphere 3). Inside the 3 balls, 3 joints are related to each other. Say
I delete the sphere 2. If you run the script, it gives the error:
Object is invalid sphere2 ok?
So my doubt is that ... how to make the script understand that you
have deleted the 2 sphere without error.
and so, the ball 1 and 3 work perfectly without the 2....
