linearGravityField() is not affecting physics bodies in the scene SceneKit

Question

I\'m trying to use a SCNPhysicsField.linearGravityField object to affect only specific objects in my scene. The problem is, that I can\'t seem to get it to affect anything.

Answer 1

Set the "downGravityCatagory" bit mask on the node:

dice.categoryBitMask = downGravityCatagory;

the physics's categoryBitMask is for physics collisions only.
