InputVRController Class
Warning
The scope of applications for UnigineScript is limited to implementing materials-related logic (material expressions, scriptable materials, brush materials). Do not use UnigineScript as a language for application logic, please consider C#/C++ instead, as these APIs are the preferred ones. Availability of new Engine features in UnigineScript (beyond its scope of applications) is not guaranteed, as the current level of support assumes only fixing critical issues.

The class manages VR controller input, serving as the primary interface for VR input.
Notice
Each instance of the InputVRController class will contain its own set of values sampled from the controller.
There are three types of VR controllers: left-hand, right-hand controllers, and a treadmill. To get the type of the VR controller, you can use the getControllerType() function.
The class provides access to the following input:
- Buttons of the VR controller, including the touch buttons. They can be either pressed or released in the current frame or continuously pressed or touched for multiple frames in a row, including the current one.
- Axes of the VR controller that detect 1-dimensional movement of the control. Depending on the type of the VR controller, there can be a different number of axes. Usually, there are 3 axes, however, UNIGINE supports up to 4.
An axis can be mapped to a control of one of the following types (also referred to as an axis type): trackpad, joystick, or trigger. Each axis type has a different number of reserved axes.
To identify the supported axes, call getNumAxes(). Additionally, you can get the axis type using getAxisType().
Notice
The article on VR Input System provides several examples of inputs on different types of OpenVR-supported controllers and information on buttons and axes mapping in UNIGINE.

Members
int getModelType ( ) #
Returns the model type of the VR controller.Return value
Controller model type.void setFilter ( float filter ) #
Sets a filter value used to correct the current state of the analog axis relative to the previous one. Axis states are interpolated for thumbsticks and triggers.Arguments
- float filter - Filter value for interpolation between axis states. The provided value is clamped to a range [0.0;1.0].
- Filter value of 0.0 means there is no interpolation and the current value is not corrected.
- Filter value of 1.0 means the previous state is used instead of the current one.
float getFilter ( ) #
Returns a filter value used to correct the current state of the analog axis (thumbsticks and triggers) relative to the previous one:- Filter value of 0.0 means there is no interpolation and the current value is not corrected.
- Filter value of 1.0 means the previous state is used instead of the current one.
Return value
Filter value.int getControllerType ( ) #
Returns the type of the VR controller.Return value
Controller type.int getNumAxes ( ) #
Returns the number of axes supported by the VR controller.Return value
Number of axes.int getAxisType ( int axis ) #
Returns the type of the specified axis.Arguments
- int axis - Axis number.
Return value
Axis type.float getAxis ( int axis ) #
Returns a state value for the specified axis. It includes position of the VR controller along the following axes: X, Y (two-axis controller) and Z (three-axis controller). When the VR controller is in the center position, X and Y axes values are zero. Negative values indicate left or down; positive values indicate right or up.Arguments
- int axis - Axis number.
Return value
Value in range [-1.0f; 1.0f].float getAxisDelta ( int axis ) #
Returns the axis delta — the difference between a new and the current state of the specified axis.Arguments
- int axis - Axis number.
Return value
Value in range [-1.0f; 1.0f].int isButtonPressed ( int button ) #
Returns a value indicating if the specified button is pressed. Check this value to perform continuous actions.Arguments
- int button - Button.
Return value
true if the button is pressed; otherwise, false.int isButtonDown ( int button ) #
Returns a value indicating if the specified button was pressed during the current frame.Arguments
- int button - Button.
Return value
true if the button was pressed; otherwise, false.int isButtonUp ( int button ) #
Returns a value indicating if the specified button was released during the current frame.Arguments
- int button - Button.
Return value
true if the button was released; otherwise, false.int isButtonTouchPressed ( int touch ) #
Returns a value indicating if the specified button is touched.Arguments
- int touch - Button.
Return value
true if the button is touched; otherwise, false.int isButtonTouchDown ( int touch ) #
Returns a value indicating if the specified touch button was "pressed" in the currect frame.Arguments
- int touch -
Return value
true if the touch button was "pressed"; otherwise, false.int isButtonTouchUp ( int touch ) #
Returns a value indicating if the specified touch button was "released" in the currect frame.Arguments
- int touch -
Return value
true if the touch button was "released"; otherwise, false.InputEventVRButton getButtonEvent ( int button ) #
Returns the currently processed VR controller button input event.Arguments
- int button - Button.
Return value
InputEventVRButtonTouch getButtonTouchEvent ( int button ) #
Returns the currently processed VR controller button touch event.Arguments
- int button - Button.
Return value
void setVibration ( unsigned short duration_ms = 100 ) #
Sets the vibration of the given duration for the VR controller.Arguments
- unsigned short duration_ms - Duration of the vibration.
