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.

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 |
|---|---|
| bool | 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.

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 |

SendHapticImpulse(float, float)
Play a haptic impulse on the controller if one is available.
Declaration
public override bool SendHapticImpulse(float amplitude, float duration)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

| Type | Name | Description |
|---|---|---|
