Struct bevy_rapier2d::prelude::MassProperties [−][src]
pub struct MassProperties {
pub local_com: OPoint<f32, Const<2_usize>>,
pub inv_mass: f32,
pub inv_principal_inertia_sqrt: f32,
}Expand description
The local mass properties of a rigid-body.
Fields
local_com: OPoint<f32, Const<2_usize>>The center of mass of a rigid-body expressed in its local-space.
inv_mass: f32The inverse of the mass of a rigid-body.
If this is zero, the rigid-body is assumed to have infinite mass.
inv_principal_inertia_sqrt: f32The inverse of the principal angular inertia of the rigid-body.
Components set to zero are assumed to be infinite along the corresponding principal axis.
Implementations
Initializes the mass properties with the given center-of-mass, mass, and angular inertia.
The center-of-mass is specified in the local-space of the rigid-body.
The world-space center of mass of the rigid-body.
The world-space inverse angular inertia tensor of the rigid-body.
Transform each element of the mass properties.
Changes the mass on these mass-properties.
The adjust_angular_inertia argument should always be true, unless
there are some specific reasons not to do so. Setting this to true
will automatically adjust the angular inertia of self to account
for the mass change (i.e. it will multiply the angular inertia by
new_mass / prev_mass). Setting it to false will not change the
current angular inertia.
Computes the mass properties of a ball.
