soft_body_sets

Like the rigid-bodies and the colliders, the soft-bodies of a simulation are stored inside of a set: the SoftBodySet. The examples of this page use the PhysicsWorld, a façade owning all the sets of one simulation, but the sets can also be used directly. Note that the insertion of a soft-body (SoftBodySet::insert) needs the rigid-body set and the collider set as well, because a soft-body owns the rigid-body standing for it and the colliders of its surface:

Example 2D

// The sets can also be used directly, without the `PhysicsWorld` façade.
let mut soft_body_set = SoftBodySet::new();
let mut rigid_body_set = RigidBodySet::new();
let mut collider_set = ColliderSet::new();
let rope = SoftBodyBuilder::rope(Vector::new(0.0, 3.0), Vector::new(2.0, 3.0), 20);
let rope_handle = soft_body_set.insert(rope, &mut rigid_body_set, &mut collider_set);
let soft_body = &soft_body_set[rope_handle];
assert_eq!(soft_body.num_particles(), 20);

Example 3D

// The sets can also be used directly, without the `PhysicsWorld` façade.
let mut soft_body_set = SoftBodySet::new();
let mut rigid_body_set = RigidBodySet::new();
let mut collider_set = ColliderSet::new();
let rope = SoftBodyBuilder::rope(Vector::new(0.0, 3.0, 0.0), Vector::new(2.0, 3.0, 0.0), 20);
let rope_handle = soft_body_set.insert(rope, &mut rigid_body_set, &mut collider_set);
let soft_body = &soft_body_set[rope_handle];
assert_eq!(soft_body.num_particles(), 20);
