« on: June 02, 2012, 01:39:41 pm »

I see that M$ releases VS2012! Now i've some question about:
How much of you use VS2012 RC?
How is C++11 support?
Can i still use sfml2 under VS2012?

Graphics / VertexArray for tilemap

« on: May 31, 2012, 12:13:12 am »

Ok, now i made a functional tilemap, but i foud a limit... cus VertexArray is a std::vector<Vertex> i can't make a 3900x3900 tile map (60 milion of vertex)
Due to private member i can't know m_vertices.max_size()
For the moment i can generate and build a 32x32*256px tilemap in some microseconds and draw it in 10 microseconds
My question, how can i know the max size of m_vertices?

For the moment i get crash at this line:

myMap.resize(nrows*ncols*4);
 

EDIT:
Ok i see that i will get some FPS crash with 350x350 map. So i suppose to set max map size to 300x300 which is the last stable FPS map size!

Graphics / Question about RenderTexture

« on: May 29, 2012, 10:05:38 pm »

I have some question about RenderTexture. I'm making a tilemap. Each tile is 256x256 px and i want to test if i can handle huge map (3900x3900). First time i used a vector and there was a very bad way. Now i've switched to RenderTexture and i draw each tile into it. The problem is one... 3900x3900 or a little example (100x100) isn't possible due to RenderTexture::create() limit. It say me i can create max 8192x8192 px texture (32x32 tile map). Now i have these questions:
1) Is max texture size same in all GPUs or is it a MY GPU limit?
2) To manage bigger map, will it be a good idea to create a vector<RenderTexture> each 32x32?

General / setFramerateLimit doesn't work

« on: May 27, 2012, 05:05:59 pm »

I've found this problem in my SFML2 RC... i'm using this code for test it:

int main(){
        sf::RenderWindow window(sf::VideoMode(1024,768,32),"FPS: ");
        window.setFramerateLimit(500);
        //window.setVerticalSyncEnabled(true);
        while (window.isOpen()){
                window.setTitle("FPS: "+GetFrameRate());
                sf::Event events;
                while (window.pollEvent(events)){
                        if (events.type == sf::Event::KeyPressed && events.key.code == sf::Keyboard::Escape)
                                window.close();
                }

                window.clear(sf::Color::Blue);
                window.display();
        }
        return EXIT_SUCCESS;
}

With VSync ON FPS are 59~61.
With or without setFramerateLimit(500) FPS are 980~991

Simple and fast:
There is a way to pause sf::Clock?

Audio / No sound inside custom class

« on: March 18, 2012, 10:52:59 pm »

I have some problem with my weapon class to fire when it's costructed.
This is what i made in Weapon constructor:

Code: [Select]

Weapon::Weapon(std::string n, const int rate, const int speed):bullets("data/bullets/"+n+"bullet.png")
{
name=n;
fireRate=rate;
bullets.setSpeed(speed);
buffer.loadFromFile("data/sounds/weapons/"+n+".wav"); //SF BUFFER
weaponSound.setBuffer(buffer); // SF SOUND
weaponSound.play();
}
If i made this in my main:

Code: [Select]

Weapon test("M60",80,1500);
It plays the sound well!
Now, i tested a little weapon vector initializer, so this is what i made:

Code: [Select]

bool loadWeaponList(std::vector<Weapon> &weaponVector){
std::string tempName;
int tempRate, tempSpeed;
std::ifstream weaponFile("data/weapons/weaponlist.txt", std::ios::in);
if (!weaponFile){
std::cerr << "Weapon List File Error!"<<std::endl;
return false;
}
while(!weaponFile.eof()){
weaponFile >> tempName >> tempRate >> tempSpeed;
weaponVector.push_back(Weapon(tempName,tempRate,tempSpeed));
}
return true;
}
The function wroks for bullets and fire, but seems sound doesn't want to start! What can be the error?

SFML projects / The Hangman

« on: March 10, 2012, 12:02:14 am »

This is my first complete project!
It sux and it is stupid but i learned a lot.
I putted it in sourceforge and maybe i've used a GPL licence on it, but really i don't know how it works :lol:  want to learn about licence and all about a software project.
Btw you can download the game at:
https://sourceforge.net/projects/thehangman/
Controls are into Readme and explained in-game!
It support English and Italian wordlist (800+, 1000+ words)
Hope you will enjoy it!
I'll w8 your comments

Graphics / Better FPS drawing 10.000 sprite

« on: March 09, 2012, 03:06:00 pm »

I'm testing this code to lern how can i get more FPS. Running it in Release without debugging mode:

Code: [Select]

#include <iostream>
#include <SFML/Graphics.hpp>

int main()
{
sf::Clock clock;
sf::Texture prova;
prova.LoadFromFile("icon.png");
std::vector<sf::Sprite> test;
for (int i=0; i<10000; ++i){
test.push_back(sf::Sprite(prova));
test[i].SetPosition(0.1*i,0.05*i);
}
sf::RenderWindow App(sf::VideoMode(1024,768,32),"Test Test",sf::Style::Close);
App.SetFramerateLimit(300);
sf::RenderTexture renderTest;
clock.Restart();
renderTest.Create(1024,768);
std::cout << clock.GetElapsedTime().AsMilliseconds() << std::endl;
while(App.IsOpen()){
sf::Event events;
while(App.PollEvent(events)){
if (events.Type == sf::Event::KeyPressed && events.Key.Code == sf::Keyboard::Escape)
App.Close();
}
renderTest.Clear(sf::Color::Blue);
clock.Restart();
for (unsigned int i=0; i<test.size(); ++i)
renderTest.Draw(test[i]);
std::cout << clock.GetElapsedTime().AsMilliseconds()<<std::endl;
renderTest.Display();

App.Clear();

// Draw the texture
sf::Sprite sprite(renderTest.GetTexture());
App.Draw(sprite);
App.Display();
}
return EXIT_SUCCESS;
}
Using playclaw/fraps i get 14~19 FPS to draw all item and less than 50ms to draw all 10.000 item into renderTest.
How can i get more FPS drawing all this 10.000 sprites?

General / Release Errors

« on: March 08, 2012, 11:37:48 pm »

My game work well when run it in debug mode (with and without debugging it) but when i switch to release i get some errors! I work on VS 2010!
Code:

Code: [Select]

#include <SFML/Graphics.hpp>

int main()
{
sf::RenderWindow App(sf::VideoMode(1024,768,32),"Test TEST tt",sf::Style::Close);
App.SetFramerateLimit(300);
sf::Font TestFont;
//TestFont.LoadFromFile("segoesc.ttf");
while(App.IsOpen()){
sf::Event events;
while(App.PollEvent(events)){
if (events.Type == sf::Event::KeyPressed && events.Key.Code == sf::Keyboard::Escape)
App.Close();
}
App.Clear(sf::Color::Blue);
App.Display();
}
return EXIT_SUCCESS;
}
So i made a little code for testing it and i discovered this:
sf::RenderWindow give this error when has a space into the title:

Eccezione non gestita a 0x7592feb8 in test.exe: 0xC0000005: Violazione di accesso nella lettura del percorso 0x53455420.

Error pointer:

Code: [Select]

-> sf::RenderWindow App(sf::VideoMode(1024,768,32),"Test TEST tt",sf::Style::Close);
If i put a title like "Test" it works well!
Now the second error. When i try to load a font i get this error:

Eccezione non gestita a 0x571c37ef (msvcr100d.dll) in test.exe: 0xC0000005: Violazione di accesso nella lettura del percorso 0x2e637365.

Error pointer in fopen.c:

Code: [Select]

-> if(*file==_T('\0'))
        {
            errno=EINVAL;
            return NULL;
        }

How can i fix these errors?

Graphics / Alternative to window.Capture()

« on: March 05, 2012, 03:39:20 pm »

I need a good alternative to window.Capture(). This function take 0.5s to take image, i need a faster function to do the same!
I read a topic where laurent said "shader" can do this!
But i can't find a good tutorial or topic that explain how put in image/texture/sprite what i see in window!

General / Keyboard.Code problems

« on: March 03, 2012, 08:11:01 pm »

I found a little bug, i don't know if is SFML related or project related, btw i've this simple if:

Code: [Select]

if (events.Type == sf::Event::KeyPressed && (events.Key.Code >= sf::Keyboard::A && events.Key.Code <= sf::Keyboard::Z))
inside this i print in console key's code (for test) and i've discovered that there are 3 non-alphabetic button that activate it!
My keyboard is this:
http://www.mygarage.ro/attachments/teste-si-review-uri/7297d1221598095-review-logitech-cordless-desktop-lx710-laser-hpim1677.jpg
and the 3 buttons are:

Numpad DEL
Num Lock
search button in the middle-up of keyboard

Numpad DEL and Num Lock have 0 as code
search button in the middle-up of keyboard has 2 as code!
There is a way to fix this?

General / PollEvent in debugging Visual Studio

« on: March 03, 2012, 03:00:41 pm »

I'm working with VS 2010 and i want to run step-by-step my program so i can manage all problem and find bugs. But i've a problem, in VS i need to press F10/F11 to move one step forward, when my program point to PollEvent() istruction it always get F10/F11 or mouseclick event, i don't know how can i give it all other comands.
My question is simple. There is a guide to use debugging in VS 2010 for SFML projects?

Graphics / MouseMoved always true

« on: February 19, 2012, 08:52:27 pm »

I've found that if i use this code somewhere:

Code: [Select]

if (Event.Type == sf::Event::MouseMoved){
std::cout<<"Mouse moved! "<<std::endl;
}
It is always true even if i don't touch mouse. Is it normal?
