Mini Tutorial:

The following example show a basic joystick implementation.

; Get the Screen Center
  Xpos=GetScreenWidth()/2
  Ypos=GetScreenHeight()/2

; start of Program loop
  Do

   ; Clear the screen
     Cls RGB(0,0,0)

   ; Display the title message
     Print "JoySticks present:"+Str$(JoySticksFound)
     Print "Use JoyStick to Move the Circle"

   ; Set the print cursor to 0,100
     SetCursor 0,100

     JoySticksFound=0

   ; Loop through and check the  4 possible Joystick devices
     For Device=1 To 4

      ; Check if this devices exists
        If JoyStatus(device)
           Print "JoyStick:"+Str$(device)

         ; check directional controls
           If JoyLeft(device) Then  Dec xpos
           If JoyRight(device) Then  Inc xpos
           If JoyUp(device) Then  Dec ypos
           If JoyDown(device) Then Inc ypos

         ; check the button States
           For button=1 To 10
              If JoyButton(device,Button)
                 Print "Pressing Button:"+Str$(Button)
              EndIf
           Next
           Print ""
           Inc JoySticksFound
        EndIf

     Next

     If JoySticksFound=0
        CenterText 400,100,"No JoyStick Present, Please Connect one !"
     EndIf

     Circle Xpos,Ypos,10,true
     Sync
