SCNPhysicsContactMBS.collisionImpulse as Double

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	SceneKit	MBS Mac64bit Plugin	20.2	✅ Yes	❌ No	❌ No	✅ Yes	Desktop & iOS

The force over time of the collision, in newton-seconds.

This property’s value tells you how hard the bodies struck each other in a collision. For example, in a game you might allow a character to proceed unhindered after a minor collision, but take damage when struck with sufficient force.

SCNPhysicsContactMBS.contactNormal as SCNVector3MBS

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	SceneKit	MBS Mac64bit Plugin	20.2	✅ Yes	❌ No	❌ No	✅ Yes	Desktop & iOS

The normal vector at the contact point between the two physics bodies, in scene coordinates.

This vector tells you which direction the bodies were moving relative to one another at the time of the collision. For example, in a game you can examine this vector to have enemy characters take damage when struck from above by the player character but damage the player character instead when they collide side-to-side.
