Unigine::ControlsSixAxis Class
| Header: | #include <UnigineControls.h> |
| Inherits from: | Controls |
This class handles Sixaxis controller input. It provides access to the following controller properties:
- Buttons represent digital buttons on the controller and can be either pressed or unpressed. Just like in the case of mouse/keyboard controls, they can be mapped to the specific controls states, to bind input events and programmed actions. You can either bind buttons in the code via setStateButton() or let the user assign the button for a control state via getStateEvent().
- D-pad is represented as four directional buttons (left, right, up and down). They are handled in the same way as other buttons.
- Thumbsticks are left and right analog directional sticks on the controller. They are queried via getLeftX() and getLeftY() for the left thumbstick and getRightX() and getRightY() for the right one. Thumbsticks also act as two digital buttons when pressed (i.e. the stick is "clicked" in). In this case, they are handled in the same way as other buttons.
- Vibration motors allow to set vibration effects. The amount of vibration for each of the motors can be set via setLargeMotor() and setSmallMotor().
- Controller position/G-sensor data can be obtained via getSensorX(), getSensorY(), getSensorZ(), and getSensorG().
Input data from analog controls (thumbsticks and triggers) can be additionally filtered via setFilter() to provide smooth interpolation between frames and avoid jerks.
A controller should update the physical state of all its input controls (i.e. check whether the user has pressed the button, for example) each frame using
updateEvents().
