# CollisionComponent.Mode.default

A default collision object.

## Declaration

```swift
case `default`
```

## Discussion

Discussion When two objects of this type collide, RealityKit computes the full contact details (contact points, normal vectors, penetration depths, and so on) and stores them in the contact set. note: Collisions will fall through and do not collide by default, to enable colliding see the CollisionComponent.Mode.colliding mode.
