DotNet / Issue querying mouse position from SFML.Net, errors in native code

« on: December 01, 2012, 07:10:09 pm »

Hello,
I have quickly tried running my SFML.Net application on arch, and for the most part it works, however I have an issue which occurs when I enter the game state, exit it and enter it again. Upon restarting the game state I get an error the first time I attempt to get the mouse position.  The error I'm getting for mono is as follows:

[ben@arch Release]$ mono TopDown.exe
MenuState::Enter()
GameState::Initialize()
MenuState::Exit()
GameState::Enter()
GameState::Exit()
MenuState::Enter()
GameState::Initialize()
MenuState::Exit()
GameState::Enter()
[xcb] Unknown request in queue while dequeuing
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.

Debug info from gdb:


=================================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
=================================================================

Aborted (core dumped)
 

I am using SFML, CFSML and SFML.Net from Git as the Keyboard.A vs Keyboard.Unknown bug is a rather large issue for my application. It functions just fine on Windows with VS2012.

Thanks,
Ben.

SFML projects / Escape! An entry to Ludum Dare

« on: August 22, 2011, 02:15:39 pm »

Hello all, this wasn't really meant for here but I thought it fitted just as well. There is a game competition called ludum dare in which you have to make a game in 48 hours. I entered and used SFML 2. My LD link is http://www.ludumdare.com/compo/ludum-dare-21/?action=preview&uid=5787. It uses every SFML library except network

Feature requests / Scaleable windows

« on: August 22, 2011, 01:50:07 pm »

It would be nice to be able to add another VideoMode so that we can have a window which sfml2 thinks is say 320 x 240 however is displayed at 640 x 480 . This would be useful for old styled games such as the one I entered for ludum dare 21, http://www.ludumdare.com/compo/ludum-dare-21/?action=preview&uid=5787 . It is one of the things I wish I could do.
