Joystick Controller

The Joystick Controller demonstrates the following

• How to install a new joystick based controller
• How to configure the controller
• How to execute code when a joystick function group and function is triggered

Since this example is loaded as a plugin, it can be used in conjunction with the released VR-Forces application

In the Launcher, click the Plug-ins button to bring up the Plug-ins Selection dialog. Enable the joystick plugin. Then launch VR-Forces.

When creating a new scenario you will also need to use the Joystick simulation model set from the developer examples simulation model sets and create the Joystick Example entity to show the new Joystick Example function group and function. This shows how to implement a button and axis function

JoystickController

This subclass of DtControllerComponent prints out a message when the function group and function are enabled and used.
