}

Cold contact data. Used as a persistent handle and for persistent island connectivity. (b2Contact)

Fields

edges: [ContactEdge; 2]

island_id: i32

A contact only belongs to an island if touching, otherwise NULL_INDEX.

island_index: i32

Index into the island’s contacts array for O(1) swap-removal. NULL_INDEX when not in an island.

set_index: i32

index of simulation set stored in World. NULL_INDEX when slot is free.

color_index: i32

index into the constraint graph color array. NULL_INDEX for non-touching or sleeping contacts, and when the slot is free.

local_index: i32

contact index within set or graph color. NULL_INDEX when slot is free.

shape_id_a: i32

shape_id_b: i32

contact_id: i32

flags: u32

contact_flags bits

generation: u32

Monotonically advanced when a contact is allocated in this slot. Used to check for invalid ContactId.
