Window / Incorrect handling of multiple controllers events

« on: August 10, 2022, 04:06:45 pm »

I am using SFML 2.5.1.

I have two Xbox One Controllers connected to my PC. Obviously they will have two ids, 0 and 1.

When I disconnect the one with id 0 (the first one) bad magic happens.

First of all, I can see a weird sequence of JoystickDisconnected/JoystickConnected events.
The 0 controller gets disconnected, and a new 0 controller gets connected.

Secondly, once the 0 controller is disconnected, events for connected controller are reported with id 0 and 1.

I wrote a simple code for tracing Joystick events.

      sf::Event event;
      while (m_window.pollEvent(event))
      {
         switch (event.type)
         {
         case sf::Event::JoystickMoved:
            {
               Diagnostics::Trace::Write("Controller move: Id:[{0}]\n", event.joystickMove.joystickId);
            }
            break;
         case sf::Event::JoystickDisconnected:
            {
               Diagnostics::Trace::Write("Controller disconnected: Id:[{0}]\n", event.joystickConnect.joystickId);
            }
            break;
         case sf::Event::JoystickConnected:
            {
               Diagnostics::Trace::Write("Controller connected: Id:[{0}]\n", event.joystickConnect.joystickId);
            }
            break;
         }
      }

This is the output after disconnecting 0 controller and moving a thumbstick on other, still connected controller.

Controller disconnected: Id:[0]
Controller connected: Id:[0]
Controller move: Id:[0]
Controller move: Id:[0]
Controller move: Id:[0]
Controller move: Id:[0]
Controller move: Id:[1]
Controller move: Id:[1]
Controller move: Id:[1]
Controller move: Id:[1]
Controller move: Id:[0]
Controller move: Id:[0]
Controller move: Id:[1]
Controller move: Id:[1]

As you can see:
1. Controller 0 gets somehow connected
2. Events are reported for both controllers 0 and 1 even there is only one controller connected.

This seems to be a bug in SFML library.
I have found two topics about similar problems, but there is no explanation what is going on.

Graphics / SFML 2.0 - Freetype library linking in graphics module

« on: September 27, 2010, 08:33:36 pm »

Hello,

I have started using SFML 2.0 in my application. Recently I have added 2 new libraries to it zlib and zziplib to be able to read zip archives. Once I linked them as static libraries I received couple of linker errors

1>LIBCMT.lib(dosmap.obj) : error LNK2005: __errno already defined in MSVCRTD.lib(MSVCR90D.dll)

All my projects are supposed to link Multithreaded Runtime libs from DLL (/MD option in VS2008), but from what I saw in dumpbin.exe reports sfml2-graphics-s-d.lib uses freetype.lib which is compiled with /MT Runtime Library option and this is not good.

Is it going to be changed in near future ?

//EDIT:

I have more problems with my application now. I cannot compile it even if i have recompiled FreeType library.

Can you tell me what version of freetype lib are you using. Maybe I have compiled wrong wersion.

//EDIT 2

I have managed to compile it correctly. I have downloaded lates version of Freetype lib. Compile it it /MD[d] option and recompile SFML 2.0

I think this issue should be fixed in SFML 2.0.[/b]
