Using the Mouse in Linux Windowed/Fullscreen Game

How can I poll the mouse in a Linux Fullscreen or Windowed game?
InitMouse() gives an error, also the documentation says the mouse commands only work for Windows...

Hi!

I've already posted it in the German forum, but perhaps somebody else here needs this, too. So if somebody have the same problem and can't use the Mousefunctions on his Linux distribution, than take a look to your /purebasic/examples/sources/sdl.pb file. You also can mix up the PB-Code with the SDL one. So here is an example for this:

Code: Select all

If SDL_Init_(#SDL_INIT_VIDEO | #SDL_INIT_AUDIO) >= 0 And InitSprite() <> 0 And OpenScreen(800, 600, 24, "Mousemovement under Linux") <> 0

 CreateSprite(0, 5, 5)
 StartDrawing(SpriteOutput(0))
  Box(0, 0, 5, 5, RGB(255,255,255))
 Stopdrawing()

 Repeat
     While SDL_PollEvent_(@Event.SDL_Event)

       Select Event\Type
      	 Case #SDL_QUIT  ; Close button of the window has been pressed
           quit = 1

;      	 Case #SDL_KEYDOWN
;	   PrintN("Key: "+Str(Event\key\keysym\sym))

	 Case #SDL_MOUSEMOTION
           PrintN("X:"+Str(Event\motion\x)+"; Y:"+Str(Event\motion\y))
       EndSelect

     Wend

   DisplaySprite(0,Event\motion\x, Event\motion\y)
   StartDrawing(ScreenOutput())
     FrontColor(255,255,255)
     Locate(Event\motion\x+5, Event\motion\y+5)
     DrawText(Str(Event\motion\x)+"; "+Str(Event\motion\y))
   StopDrawing()

  FlipBuffers() : ClearScreen(0,0,0)
 Until Event\key\keysym\sym = #SDLK_ESCAPE Or quit = 1
Else
 MessageRequester("Error", "Couldn't initialize SDL or was unable to open a 800*600 24-bit screen!", 0)
 End
Endif

best regards,
Christian

Fine!

Works the normal mouse library of PB on your system?

i already posted it in the german forum: i tried it again with a clean linux installation, but then something with the graphic driver went wrong and well.... i'll try again in six months, perhaps i'll have better luck then :roll:

@TronDoc:

See helpfile!

@The_Pharao:
Take a look in the Suse Support, perhaps you'll find something to solve your problem. Good luck for the next try with Linux.
