Graphics / sf::RenderWindow vs sfml/qt

« on: July 23, 2010, 12:22:40 am »

Situation:

I'm using OpenSuse 11.3 with the opensource "radeon" driver for my ATI X1200 (RS690). Performance is worse than it was under 11.2. Funny thing is that qt/SFML app gives me better framerate (within tolerance) than the solo SFML window (way too slow).

Questions

What is the difference in implementation between a sf::RenderWindow and SFML/qt view? Is the former using overlay? If that is the case, it is possible to disable the use of overlay as the "radeon" driver doesn't seem to support them?

Regards,
Frank B.

SFML projects / LGCK Builder was updated to 0.5.0.1a

« on: July 08, 2010, 07:12:27 pm »

What's new in 0.5.0.1a

- parallax scrolling support
- inventory system
- scripting event model
- customizable overlay displays (scores, time left, lives etc.)
- wrap around on all four sides. (think pac-man)
- better monster AIs when gravity is turned off

General / Converting keycodes

« on: July 05, 2010, 05:41:15 pm »

That's what I was afraid of.

It just so happens that I have a qt/sfml application that works rather well except for those moments when the sfml windows decides to lose input focus and no longer receives messages.

My workarround was to grab the messages from qt and feed them to key mapper code that normally processes the sfml msg queue. The idea does what it is intended with the few keys that are used to manipulate the sfml view. However, I plan to let the user redefine the keys so that leaves me open to the whole problem again.

That's where having a mean to do the convertion would be very useful. Not just to work arround the issue but also to let the user define shortcuts sequences (he's press keys in qt dialog, I'd convert those keys to sfml equivants for use later in the sfml windows).

Frank B.

Is there an easy way to convert qt keycodes to SFML and vice versa?

How can you possibly only support a specific desktop environment? They will all run each others' programs.

Good point. It's been tested on KDE. I know it works there. (I updated the topic accordingly)

If someone would be willing to help me test it on other Linux desktop enviroments, I could supply them with a compiled Linux binary and we could all have some fun!

Wow, 20,000 lines and it's not done?

20k is not all that big. That's roughly 10,000 for the shared libraries. (of which CGame and CGameState account for more than 5,000). The remaining 10,000 are split between the GUI of LGCK Builder and OBL4EDIT.And yes it's not finished but you can still make games with it. The goal is to include many more features than currently available today.

What we need mostly is feedback !

Let us know how we can improve it !

Audio / Error message with sfml-audip

« on: December 21, 2009, 12:01:04 am »

I was too eager to report on the good news ! :cry:

The game module stopped crashing because of the work around.

#ifdef SFML
sf::SoundBuffer snd;
sleep(1);
#endif

It doesn't change anything as far as the test application goes.

Someone on another forum suggested this could be a problem with the version of openAL shipped with OpenSuse 11.2. Any ideas?

Code: [Select]



// main.cpp
//

#include <QFile>
#include "Snd.h"

int main(int argc, char *argv[])

        qDebug("file opened\n");
        int size = file.size();
        char * buf = new char[size];;
        file.read(buf, size);

        char t[5];
        t[4] = 0;
        memcpy(t, buf, 4);
        qDebug("header: %s\n", t);

        CSnd snd;
        snd.Create(buf, size, QString("test"));
        snd.Play();

        delete [] buf;
