joystick object
This method explicitly opens a joystick device on the user's system.
bool set(int index)
Parameters:
index
The index of the device to open (see remarks).
Return value:
true on success, false on failure.
Remarks:
The index corresponds to the list returned by list_joysticks, and is zero-based, ranging from 0 to joysticks minus 1.
If no joystick is explicitly opened, the engine will automatically open the user's preferred joystick as set in control panel. This is done when the joystick object instance is first created.
Example:

    // Enumerate the list of joysticks and display information on the first available.

    void main()
    {
    joystick stick;
    show_game_window("Joystick Test");
    if(stick.joysticks==0)
    {
    alert("Error", "No joysticks seem to be attached.");
    exit();
    }
    string[] names=stick.list_joysticks();
    for(int i=0;i<names.length();i++)
    alert("Joystick " + (i+1), names[i]);
    stick.set(0);
    if(stick.active==false)
    {
    alert("Error", "Could not open the joystick device.");
    exit();
    }
    alert("Information", "Buttons: " + stick.buttons + "\nSliders: " + stick.sliders + "\nPovs: " + stick.povs);
    }
