[ASK] Trying to create a 2D physics blob

[hamdirizal]

Hi, Guys. 

I am trying to create a blob ball using p2js. What I am trying to achieve is something like the "Sushi Cat" game.

I created a blob using the structure in the picture A (attached). The gray orbits are allowed to penetrate each other, and the red lines are distantConstraint.

But the problem is when the blob fell from a high place (or hitting corner), it becomes like in picture B.

I tried to use spring, different constraint force, smaller orbits, but they are not working properly.
 

My questions are;

1. What is the solution for this?

2. Is there any other js physics engine that has a specific feature to do this task?

 

Any help is greatly appreciated. 

Thanks.
