}Expand description
A trait for computing MassProperties2d for 2D objects.
For the 3D equivalent, see ComputeMassProperties3d.
Required Methods§
Sourcefn unit_angular_inertia(&self) -> f32
fn unit_angular_inertia(&self) -> f32
Computes the angular inertia corresponding to a mass of 1.0.
Sourcefn center_of_mass(&self) -> Vec2
fn center_of_mass(&self) -> Vec2
Computes the local center of mass relative to the object’s origin.
Provided Methods§
Sourcefn angular_inertia(&self, mass: f32) -> f32
fn angular_inertia(&self, mass: f32) -> f32
Computes the angular inertia corresponding to the given mass.
Equivalent to mass * shape.unit_angular_inertia().
Sourcefn mass_properties(&self, density: f32) -> MassProperties2d
fn mass_properties(&self, density: f32) -> MassProperties2d
Computes the MassProperties2d with a given density.
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
