Soft body for L shape?

I am creating a soft body according to the following video tutorial:

But when I convert to L shape, it doesn't achieve the desired result because I don't know how to find the center of L shape?
Thanks for reading.

 

Video tutorial to create softbody for circle shape. They use 1 point in the center of the circle and 5 points around using 2d spring joint to connect together. They then used sprite shapes to create a circle shape based on the points I mentioned above. I'm wondering how can I create L shape from sprite shape controller whose points have spring joint 2d together?

 

A circle has a single center point. An L does not.

So the first thing you need to experiment around with is having several center points.. or even a center object / shape which cannot be deformed. Around this / these you can then attach your wiggle bits and pieces to achieve the wanted effect. How exactly you do this is up to experimentation.

Or you look for a tutorial more closely matching your usecase, even if some circumstances are different, ie it being about 3D objects. You then need to transfer the learned knowledge to your own usecase and apply it.

 

I have the above points connected together by spring joint 2d. Is there any way to create L shape from the other points?
