PhysicsJS Friction Behavior

Question

I am new to physicsjs and am creating some test simulations in order to become familiar with the library.

I want to simulate multiple boxes sliding across the screen which all experience different degrees of friction. So far I have 3 boxes which start on the left border of the screen and all have a pos xvel. I am unsure what the best approach is to add friction to the simulation. all 3 boxes should not be affected the same way by friction. Therefor i need some way of applying a general friction algorithm to all the boxs, however the amount of friction needs to depend on what box it is currently acting on.

Answer 1

Friction is built in (but it's not the greatest algorithm).

Just use:

Physics.body('rectangle', {
     width: 40,
     height: 40,
     cof: 0.5, // <-- change the friction. range [0, 1]
     x: ...
     ...
});
