Device Handling

After you have created an instance of EM_JOYSTICK you have now full control of your joystick.

Basically they are two levels of controls. One level is on system scale and the other one is on device scale.

Handling on System Scale

To access all features on system scale you need to inherit from EM_SHARED_SUBSYSTEMS where you will find a singleton called joystick_subsystem. This singleton is an instance of EM_JOYSTICK_SUBSYSTEM with some features to get more information about all CD-Rom devices of your system.

E.g.: You can get the name of a device or count how many devices they are connected to your system.

Note: Those Information are updated during runtime, therefore they can change.

Handling on Device Scale

To access all features on device scale you need to create an instance of EM_JOYSTICK as mentioned above. This class will give you features to handle any Joystick's and to get information the current joystick state.

Note: Getting your information directly from a joystick device is very slow. It is much better to use joystick events, which contains information about every desired state changes. See below for more information.

Here is a list of all avaiable status information directly from your joystick:
