Struct b2ContactHitEvent 

#[repr(C)]
pub struct b2ContactHitEvent {
    pub shapeIdA: b2ShapeId,
    pub shapeIdB: b2ShapeId,
    pub contactId: b2ContactId,
    pub point: b2Vec2,
    pub normal: b2Vec2,
    pub approachSpeed: f32,
}

A hit touch event is generated when two shapes collide with a speed faster than the hit speed threshold. This may be reported for speculative contacts that have a confirmed impulse.

Fields

shapeIdA: b2ShapeId

Id of the first shape

shapeIdB: b2ShapeId

Id of the second shape

contactId: b2ContactId

Id of the contact. @warning this contact may have been destroyed @see b2Contact_IsValid

point: b2Vec2

Point where the shapes hit at the beginning of the time step. This is a mid-point between the two surfaces. It could be at speculative point where the two shapes were not touching at the beginning of the time step.

normal: b2Vec2

Normal vector pointing from shape A to shape B

approachSpeed: f32

The speed the shapes are approaching. Always positive. Typically in meters per second.
