This entity’s collider that touched first, by its place in its collider list.
entityKey
string
This entity’s stable key.
impulse
number
The solver’s contact impulse between the two in the step they first touched, in newton-seconds: what a pinball bumper scores by.
normal
Vector3
The contact’s normal, in world space, from this entity to the other.
other
Entity | null
The entity it touched; null once that entity is destroyed.
otherColliderIndex
number
The other entity’s collider that touched first.
otherKey
string
The other entity’s stable key, which outlives it, as the stream and the dump name it.
point
Vector3
Where they first touched, in world space.
relativeVelocity
Vector3
The other’s velocity at the point less this one’s, in metres a second, before the step’s solve: a box dropped at 5 m/s reads about 5 m/s, not what is left after it lands.
