Struct b2ContactHitEvent 

#[repr(C)]
pub struct b2ContactHitEvent {
    pub shapeIdA: b2ShapeId,
    pub shapeIdB: b2ShapeId,
    pub contactId: b2ContactId,
    pub point: b2Pos,
    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: b2Pos

Point where the shapes hit. This is a mid-point between the two surfaces. It could be a speculative point where the shapes were not touching at the beginning of the time step. The point is reconstructed after the step, so when both bodies are moving it may trail the impact by up to one step of motion.

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.
