Detailed Description

The QObjectPicker class instantiates a component that can be used to interact with a QEntity by a process known as picking.

The signals pressed(), released(), clicked(), entered(), and exited() are emitted when the bounding volume defined by the pickAttribute property intersects with a ray.

Note: Instances of this component shouldn't be shared, not respecting that condition will most likely result in undefined behavior.
