Struct libliquidfun_sys::box2d::ffi::b2MassData

#[repr(C)]
pub struct b2MassData {
    pub mass: f32,
    pub center: b2Vec2,
    pub I: f32,
}

This holds the mass data computed for a shape.

Fields

mass: f32

The mass of the shape, usually in kilograms.

center: b2Vec2

The position of the shape’s centroid relative to the shape’s origin.

I: f32

The rotational inertia of the shape about the local origin.

Implementations
