Class ActionBasedController
Interprets feature values on a tracked input controller device using actions from the Input System into XR Interaction states, such as Select. Additionally, it applies the current Pose value of a tracked device to the transform of the GameObject.

public class ActionBasedController : XRBaseControllerRemarks
This behavior requires that the Input System is enabled in the Active Input Handling setting in Edit > Project Settings > Player for input values to be read. Each input action must also be enabled to read the current value of the action. Referenced input actions in an Input Action Asset are not enabled by default.
Properties
activateAction
The Input System action to use for activating a selected Interactable. Must be an action with a button-like interaction where phase equals performed when pressed. Typically a ButtonControl Control or a Value type action with a Press or Sector interaction.

The Input System action to read values for selecting an Interactable. Must be an AxisControl Control or Vector2Control Control.
Declaration
public InputActionProperty selectActionValue { get; set; }Property Value
| Type | Description |
|---|---|
| InputActionProperty |
Remarks
Optional, Unity uses selectAction when not set.
See Also
trackingStateAction
The Input System action to read the Tracking State when updating this GameObject position and rotation; falls back to the tracked device's tracking state that drives the position or rotation action when not set. Must be an IntegerControl Control.
Declaration

translateAnchorAction
The Input System action to use for translating the interactor's attach point closer or further away from the interactor. Must be a Vector2Control Control. Uses the y-axis as the translation input.
Declaration

Methods
IsPressed(InputAction)
Evaluates whether the given input action is considered performed. Unity automatically calls this method during UpdateInput(XRControllerState) to determine if the interaction state is active this frame.
Declaration
protected virtual bool IsPressed(InputAction action)Parameters
| Type | Name | Description |
|---|---|---|
| InputAction | action | The input action to check. |
Returns
| Type | Description |
|---|---|
| Boolean | Returns true when the input action is considered performed. Otherwise, returns false. |
Remarks
More accurately, this evaluates whether the action with a button-like interaction is performed. Depending on the interaction of the input action, the control driving the value of the input action may technically be pressed and though the interaction may be in progress, it may not yet be performed, such as for a Hold interaction. In that example, this method returns false.

OnDisable()
See MonoBehaviour.
Declaration
protected override void OnDisable()Overrides
OnEnable()
See MonoBehaviour.
Declaration
protected override void OnEnable()Overrides
ReadValue(InputAction)
Reads and returns the given action value. Unity automatically calls this method during UpdateInput(XRControllerState) to determine the amount or strength of the interaction state this frame.
Declaration
protected virtual float ReadValue(InputAction action)Parameters
| Type | Name | Description |
|---|---|---|
| InputAction | action | The action to read the value from. |
Returns
| Type | Description |
|---|---|
| Single | Returns the action value. If the action is null returns the default float value ( |
See Also
SendHapticImpulse(Single, Single)
Play a haptic impulse on the controller if one is available.
Declaration
public override bool SendHapticImpulse(float amplitude, float duration)Parameters
| Type | Name | Description |
|---|---|---|
| Single | amplitude | Amplitude (from 0.0 to 1.0) to play impulse at. |
| Single | duration | Duration (in seconds) to play haptic impulse. |
Returns
| Type | Description |
|---|---|
| Boolean |
Overrides
UpdateInput(XRControllerState)
Updates the XR Interaction states in the given controller state based on the current inputs of the controller device. Unity calls this automatically during UpdateController() so explicit calls to this function are not required.
Declaration
protected override void UpdateInput(XRControllerState controllerState)Parameters
| Type | Name | Description |
|---|---|---|
| XRControllerState | controllerState | The state of the controller. |
Overrides
UpdateTrackingInput(XRControllerState)
Updates the pose values in the given controller state based on the current tracking input of the controller device. Unity calls this automatically from FixedUpdate(), OnBeforeRender(), and UpdateController() so explicit calls to this function are not required.
Declaration
protected override void UpdateTrackingInput(XRControllerState controllerState)Parameters
| Type | Name | Description |
|---|---|---|
| XRControllerState | controllerState | The state of the controller. |
