Window / Error in the OpenGL Version Picking

« on: October 21, 2012, 10:36:09 pm »

A while back, it was suggested that if an SFML window fails to create an OpenGL context of a specific, requested version (say, 4.3), it falls back to a previous version, and continues to do so until it finds a supported version. Right now, I have a bit of code that creates a window with an OpenGL version of 4.3 (but my graphics cards only supports up to 4.2), and instead of falling back to a previous version of OpenGL, it instead crashes with the following error:

X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  153 (GLX)
  Minor opcode of failed request:  34 ()
  Serial number of failed request:  89
  Current serial number in output stream:  90

I am using the latest version of SFML2 from the repository. I did search for this error, but found nothing.

A complete and minimal source that demonstrates this is here.

I'm running an NVidia GTX 460 on Arch Linux. Drivers are proprietary, 304.51. I just updated to 304.60 though, so I will test with those as well and edit with the results.

Graphics / RenderTexture Speed

Quick question: how slow is the creation of a RenderTexture? How bad would it be to create one per frame?

Graphics / Font Sizes, how do they work?!

« on: September 17, 2011, 03:32:45 am »

I know that font size works by setting the height of a specific character to the chosen height in pixels, and scales other pixels accordingly, but I forget which character this is.
Also, if I set the font size to 12, what's the height of the tallest character in an average font, say Arial?

General discussions / Estimated time to new Graphics API?

It doesn't even need to be precise. A guesstimate would be fine. Please, just give us something to go on! I'm dying here!

General discussions / Premake

You don't have to use it. Just want you to look at it. I think it looks far superior to CMake (imo). Might be a good idea. Looks like it's far easier to grasp.

Network / Latest update broke packets

/home/onilink/Desktop/SFML/src/SFML/Network/Packet.cpp:97:31: error: invalid conversion from ‘const void*’ to ‘void*’
Congratulations on missing this, Laurent!

SFML website / Nitpicking the Documentation

« on: May 23, 2011, 02:13:32 am »

Was looking through the documentation, found this:
Structure defining a page if glyphs.
Sorry to nitpick, but I'd like it if this were fixed.

Audio / SoundBuffer multiple channel sample organization

« on: May 20, 2011, 05:37:03 am »

When there are multiple channels in a sound buffer, how are the samples organized? Do they alternate between channels like
1,2,3,4,1,2,3,4,1,2,3,4?
Do they sort themselves by channel like
1,1,1,2,2,2,3,3,3,4,4,4?
Do they do something else?

SFML projects / Terra Game Engine

« on: April 18, 2011, 04:26:32 am »

Hey guys, OniLink here, and I have something for you!
I've been working on this game engine for quite a while now, and I think it's ready for public release.

The Terra Game Engine is a game engine designed to be easy to use in the creation of 2D games. It provides an object manager, resource manager, level loader, game loop, and more! It is written in pure C++0x, and conforms to the portions of the standard implemented in GCC 4.6.

Repository
Task Tracker
The level and configuration files are stored in XML files, which are parsed by RapidXML.

The engine runs on the latest build of SFML2, so make sure you have it! Any dynamic libraries, including the SFML libraries, must be provided by you when distributing the games made with this engine.

There are currently no tutorials. Soon, I will begin making tutorials for this engine.

If anyone has any suggestions or error reports, post them on the Task Tracker. If anyone wishes to become a developer, please let me know.

General / CMake FindSFML Guide

« on: March 18, 2011, 12:16:03 am »

Can someone explain to me how to use FindSFML? I can't find any information on it. Specifically, how do I choose between locating the Debug modules and Release modules?

General / Linux Dynamic Libraries

« on: March 10, 2011, 02:05:23 am »

I am preparing my game engine for use by developers, but I need to know something: Which libraries do I need to include with the engine? I have it set up to use libraries in the binary's directory, but I'm not sure which libraries are used by SFML that I need to include. Help?

General / SFML2 Build 32-bit libraries on 64-bit system

« on: March 09, 2011, 06:11:32 am »

I need to be able to compile SFML for both 32-bit and 64-bit Linux from a 64-bit desktop so that I can distribute games for both 32-bit and 64-bit. However, I do not know the steps needed to compile 32-bit on Linux with cmake. I have the multilib GCC installed, so that isn't a problem.

Graphics / wxWidgets with SFML2?

Does the SFML 1.6 tutorial for binding wxWidgets and SFML together work for SFML2?

Window / Segmentation Fault when Window is Closed

« on: November 21, 2010, 09:28:26 pm »

Every time I close an SFML window on Linux, I get a segmentation fault. It even happens in the examples.

Graphics / GetFrameTime returns time for current or previous frame?

« on: November 21, 2010, 07:42:30 am »

The documentation is slightly confusing. It says:
Get the time elapsed since the last frame.

This function returns the time elapsed during the last frame. This can be useful for calculating the framerate, or for updating the application's objects.

It has two conflicting meanings: elapsed time so far in current frame, and elapsed time in previous frame.

Which of the two does it mean?
