SCNPhysicsWorldMBS.SCNPhysicsTestBackfaceCullingKey as String

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

The key for choosing whether to ignore back-facing polygons in physics shapes when searching for contacts.

The value for this key is a Boolean value. The default value is true, specifying that the search should only return contacts with the exterior surfaces of any physics shapes. Change the value to false to consider contacts with both interior and exterior surfaces.

This key applies only to ray and convex sweep tests, and only to physics shapes created using the SCNPhysicsShapeTypeConcavePolyhedron option.

SCNPhysicsWorldMBS.SCNPhysicsTestCollisionBitMaskKey as String

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

The key for selecting which categories of physics bodies that SceneKit should test for contacts.

The value for this key is an unsigned Integer value. SceneKit tests for contacts only with physics bodies whose categoryBitMask property overlaps with this bit mask. The default value is SCNPhysicsCollisionCategoryAll, specifying that searches should test all physics bodies regardless of their category.

SCNPhysicsWorldMBS.SCNPhysicsTestSearchModeAll as String

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

One of the option values for SCNPhysicsTestSearchModeKey key.

Searches should return all contacts matching the search parameters.

SCNPhysicsWorldMBS.SCNPhysicsTestSearchModeAny as String

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

One of the option values for SCNPhysicsTestSearchModeKey key.

Searches should return only the first contact found regardless of its position relative to the search parameters.

SCNPhysicsWorldMBS.SCNPhysicsTestSearchModeClosest as String

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

One of the option values for SCNPhysicsTestSearchModeKey key.

Searches should return only the closest contact to the beginning of the search.

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

The key for selecting the number and order of contacts to be tested.

See Physics Test Search Modes for possible values. The default value is SCNPhysicsTestSearchModeAny.
This key applies only to ray and convex sweep tests.
