Struct SoftBodySharedSettingsBuilder 

pub struct SoftBodySharedSettingsBuilder { /* private fields */ }

Collects the vertices, faces and constraints of SoftBodySharedSettings; made by SoftBodySharedSettings::builder.

Implementations

impl SoftBodySharedSettingsBuilder

pub fn create_constraints( self, bend: SoftBodyBendType, attributes: SoftBodyVertexAttributes, ) -> Self

Creates edge, shear, bend and LRA constraints from the faces, every vertex with the same attributes (Jolt SoftBodySharedSettings::CreateConstraints, with its default angle tolerance of 8° for detecting quads). Replaces an earlier call.

pub fn create_constraints_per_vertex( self, bend: SoftBodyBendType, attributes: Vec<SoftBodyVertexAttributes>, ) -> Self

Like create_constraints with one attribute set per vertex, in vertex order; there must be exactly as many as vertices.

pub fn edge(self, edge: SoftBodyEdge) -> Self

Adds an edge constraint, kept in addition to the generated ones. Long range attachments follow the generated edges only.

pub fn dihedral_bend(self, bend: SoftBodyDihedralBend) -> Self

Adds a dihedral bend constraint, kept in addition to the generated ones.

pub fn volume(self, volume: SoftBodyVolume) -> Self

Adds a volume constraint, for example one per tetrahedron of a solid soft body.

pub fn build(self) -> Result<SoftBodySharedSettings, SoftBodyError>

Checks everything and builds the settings; nothing is allocated when a check fails.

Fails with SoftBodyError::InvalidValue when:

• there is no vertex;
• a vertex position is beyond limits::MAX_SHAPE_EXTENT, a velocity beyond limits::MAX_LINEAR_VELOCITY, or an inverse mass neither 0 nor the inverse of a mass within limits::MIN_MASS..=limits::MAX_MASS;
• the masses of the movable vertices add up to more than limits::MAX_MASS (Jolt gives the body their sum as its mass);
• a face names a vertex that does not exist or one vertex twice, has no area, or has an edge shorter than limits::MIN_SOFT_BODY_EDGE_LENGTH;
• with SoftBodyBendType::Distance, the vertices opposite a shared edge are closer than that length (the bend edge between them would have no length);
• an attribute is out of range, or a per-vertex attribute does not have one value per vertex;
• an explicit constraint names a vertex that does not exist or one vertex twice, has a compliance out of range or an edge (or a bend’s shared edge) shorter than limits::MIN_SOFT_BODY_EDGE_LENGTH, or is a tetrahedron without volume.
