The short answer is:
getTriggeringPath() returns the scene graph path to the
"object it collided with".
getArmingPath() returns the scene graph path to the "current
object".
The long answer:
In the collision, there are four important objects:
1. The Behavior object which has
2. a WakeupCondition of WakeupOnCollisionEntry
3. The arming node/path (or bounds)
4. The triggering node/path (or bounds)
The specification of USE_GEOMETRY will use a node/path
The specification of USE_BOUNDS will use a bounds instead (for speed)
The arming node/path is the node for which collisions are detected.
You can think of the Behavior and the WakeupCondition as being
associated with the arming node.
The triggering node/path is the object which collided with the
arming node/path.
The path is returned instead of a node so that you have maximum
flexibility in responding to the collision. It could be you
want to operate on the visual objects, or it could be you want
to operate on the scene graph path (perhaps a TransformGroup)
to the visual object.
Hope this helps,
