XR Grab Interactable

Interactable component that hooks into the interaction system (via XRInteractionManager) to allow basic "grab" functionality. Can attach to a selecting Interactor and follow it around while obeying physics (and inherit velocity when released).

Property	Description
Interaction Manager	The XRInteractionManager that this Interactable will communicate with (will find one if None).
Interaction Layer Mask	Allows interaction with Interactors whose Interaction Layer Mask overlaps with any Layer in this Interaction Layer Mask.
Colliders	Colliders to use for interaction with this Interactable (if empty, will use any child Colliders).
Custom Reticle	The reticle that appears at the end of the line when valid.
Select Mode	Indicates the selection policy of an Interactable. This controls how many Interactors can select this Interactable. The value is only read by the Interaction Manager when a selection attempt is made, so changing this value from Multiple to Single will not cause selections to be exited.
Single	Set Select Mode to Single to prevent additional simultaneous selections from more than one Interactor at a time.
Multiple	Set Select Mode to Multiple to allow simultaneous selections on the Interactable from multiple Interactors.
Movement Type	Specifies how this object moves when selected, either through setting the velocity of the Rigidbody, moving the kinematic Rigidbody during Fixed Update, or by directly updating the Transform each frame.
Velocity Tracking	Set Movement Type to Velocity Tracking to move the Interactable object by setting the velocity and angular velocity of the Rigidbody. Use this if you don't want the object to be able to move through other Colliders without a Rigidbody as it follows the Interactor, however with the tradeoff that it can appear to lag behind and not move as smoothly as Instantaneous.
Kinematic	Set Movement Type to Kinematic to move the Interactable object by moving the kinematic Rigidbody towards the target position and orientation. Use this if you want to keep the visual representation synchronized to match its Physics state, and if you want to allow the object to be able to move through other Colliders without a Rigidbody as it follows the Interactor.
Instantaneous	Set Movement Type to Instantaneous to move the Interactable object by setting the position and rotation of the Transform every frame. Use this if you want the visual representation to be updated each frame, minimizing latency, however with the tradeoff that it will be able to move through other Colliders without a Rigidbody as it follows the Interactor.
Retain Transform Parent	Enable to have Unity set the parent of this object back to its original parent this object was a child of after this object is dropped.
Track Position	Enable to have this object follow the position of the Interactor when selected.
Smooth Position	Enable to have Unity apply smoothing while following the position of the Interactor when selected.
Smooth Position Amount	Scale factor for how much smoothing is applied while following the position of the Interactor when selected. The larger the value, the closer this object will remain to the position of the Interactor.
Tighten Position	Reduces the maximum follow position difference when using smoothing. Fractional amount of how close the smoothed position should remain to the position of the Interactor when using smoothing. The value ranges from 0 meaning no bias in the smoothed follow distance, to 1 meaning effectively no smoothing at all.
Velocity Damping	Scale factor of how much to dampen the existing velocity when tracking the position of the Interactor. The smaller the value, the longer it takes for the velocity to decay. Only applies when Movement Type is in Velocity Tracking mode.
Velocity Scale	Scale factor Unity applies to the tracked velocity while updating the Rigidbody when tracking the position of the Interactor. Only applies when Movement Type is in Velocity Tracking mode.
Track Rotation	Enable to have this object follow the rotation of the Interactor when selected.
Smooth Rotation	Apply smoothing while following the rotation of the Interactor when selected.
Smooth Rotation Amount	Scale factor for how much smoothing is applied while following the rotation of the Interactor when selected. The larger the value, the closer this object will remain to the rotation of the Interactor.
Tighten Rotation	Reduces the maximum follow rotation difference when using smoothing. Fractional amount of how close the smoothed rotation should remain to the rotation of the Interactor when using smoothing. The value ranges from 0 meaning no bias in the smoothed follow rotation, to 1 meaning effectively no smoothing at all.
Angular Velocity Damping	Scale factor of how much Unity dampens the existing angular velocity when tracking the rotation of the Interactor. The smaller the value, the longer it takes for the angular velocity to decay. Only applies when Movement Type is in VelocityTracking mode.
Angular Velocity Scale	Scale factor Unity applies to the tracked angular velocity while updating the Rigidbody when tracking the rotation of the Interactor. Only applies when Movement Type is in Velocity Tracking mode.
Throw On Detach	Enable to have this object inherit the velocity of the Interactor when released. This is not supported for a kinematic Rigidbody.
Throw Smoothing Duration	Time period to average thrown velocity over.
Throw Smoothing Curve	The curve to use to weight thrown velocity smoothing (most recent frames to the right).
Throw Velocity Scale	Scale factor Unity applies to this object's velocity inherited from the Interactor when released.
Throw Angular Velocity Scale	Scale factor Unity applies to this object's angular velocity inherited from the Interactor when released.
Force Gravity On Detach	Forces this object to have gravity when released (will still use pre-grab value if this is false / unchecked).
Attach Transform	The attachment point Unity uses on this Interactable (will use this object's position if none set).
Attach Ease In Time	Time in seconds Unity eases in the attach when selected (a value of 0 indicates no easing).
Attach Point Compatibility Mode	Controls the method used when calculating the target position of the object. Use AttachPointCompatibilityMode.Default for consistent attach points between all XRBaseInteractable.MovementType values. Marked for deprecation, this property will be removed in a future version. This is a backwards compatibility option in order to keep the old, incorrect method of calculating the attach point. Projects that already accounted for the difference can use the Legacy option to maintain the same attach positioning from older versions without needing to modify the Attach Transform position.
