Class XRInteractionManager

The Interaction Manager acts as an intermediary between Interactors and Interactables. It is possible to have multiple Interaction Managers, each with their own valid set of Interactors and Interactables. Upon being enabled, both Interactors and Interactables register themselves with a valid Interaction Manager (if a specific one has not already been assigned in the inspector). The loaded scenes must have at least one Interaction Manager for Interactors and Interactables to be able to communicate.

public class XRInteractionManager : MonoBehaviour
Remarks

Many of the methods on the Interactors and Interactables are designed to be called by this Interaction Manager rather than being called directly in order to maintain consistency between both targets of an interaction event.

Properties

hoverFilters

The list of global hover filters in this object. Used as additional hover validations for this manager.

Declaration
public IXRFilterList<IXRHoverFilter> hoverFilters { get; }
Property Value
Type Description
IXRFilterList<IXRHoverFilter>
Remarks

While processing hover filters, all changes to this list don't have an immediate effect. These changes are buffered and applied when the processing is finished. Calling MoveTo(T, int) in this list will throw an exception when this list is being processed.

See Also
