General / [Solved]Draw FPS each second

« on: October 31, 2010, 06:07:02 pm »

Hi,
I'm trying to make a function that would draw how many FPS were displayed each second.
The original function is:

Code: [Select]

double app_properties::draw_fps()
{
stringstream ss;
getfps=1/(App.GetFrameTime()); //getfps is a float declared in the app_properties class
ss << getfps;
dfps.SetText("FPS: " + (ss.str()).substr(0,2)); //dfps is a font string declared in the app_properties class
App.Draw(dfps);
return getfps;
}

How could I change this and make it draw the FPS only each second?
This is probably very easy to do, but I'm being dumb...

Thanks in advance!

General / [Solved]Problem Setting up Code::Blocks

« on: October 16, 2010, 01:55:22 am »

Yet again another thread of a problem I couldn't solve for myself... Hope I'm not getting annoying.

I tried to set up SFML on Code::Blocks, following the documentation on the tutorial section but I'm not being very successful.

I think I did everything right, but when I try to compile a simple code using static libraries (I.E. -lsfml-system-s), I get the following:


However, when I use -lsfml-system, it compiles just fine.
What could be wrong?

Thanks in advance

General / Capture Enter Key

« on: October 15, 2010, 03:27:21 pm »

Hi, I believe this is very simple to do but I'm probably being thick.

How can I capture the enter key, in order to confirm a selection.
I tried App.GetInput().IsKeyDown(Key::Enter) but I that's not correct since Key doesn't have the "Enter" option.

Thanks in advance.

General / Thread Priority

« on: October 04, 2010, 01:17:58 am »

Hello, once again.
Sorry for creating so many threads in a short amount of time but since I'm on a learning phase, I really want  to solve my questions.

Is there a way to change the priority of a thread?
I noticed all the threads I create are being executed with "Lowest" priority.


On the image, the worker thread plays a music, but since it's running on lowest priority, whenever I do something outside of the application (Open browser, open a folder, open a winrar archive, etc...) the music starts slowing down and skipping.

Is there a way to change this? Or should I stop using SFML thread classes?
Thanks in advance.

General / Pass data to a thread function

« on: October 02, 2010, 04:19:34 am »

Hi, I have a simple question about passing a variable to a thread function that I think it's easy to answer.

I was following this tutorial:
http://www.sfml-dev.org/tutorials/1.6/system-threads.php
And I read the part that explains my question, however I'm not having success when I try to pass a variable to the thread function.


I have the variable int n declared on the main, where n's value is 5.
Now I want to pass this value to a threaded function.
I tried the following:

Code: [Select]


void print_Console(void *UserData)
{
int* n = static_cast<int*>(UserData);
cout << "n=" << *n << endl;
}

int main()
{
int n=2; //EDITED AT Sat Oct 02, 2010 11:50 am
Thread th1(&print_Console, &n);
th1.Launch();
}


But it's not outputting n correctly.
So, what could be wrong here?

Thanks in advance

Audio / Failed to load sound buffer from file

« on: September 29, 2010, 08:26:38 pm »

Hi, I'm new to the forums so I'm not sure if I'm posting in the correct section, but here it goes.

I tried making a program in Visual Studio C++ 2008 using SFML, that would play a simple .wav file. However when I run it I only get the message:
"Failed to load sound buffer from file "sound.wav".

The code is the default one provided on the Audio tutorial:
http://www.sfml-dev.org/tutorials/1.6/audio-sound.php

source file in: http://www.sfml-dev.org/tutorials/1.6/sources/audio-sound.cpp

I've included libsndfile-1 and openal32 on the exe folder. The sound is present on the folder as well and is named sound.wav

What could be wrong?

Thanks in advance for any help
