Graphics / Re: Clear or reset a texture?

« on: March 27, 2014, 10:10:17 pm »

Oh, I may have misunderstood your question
Hmm. So when you update a texture with a smaller image, the old content to get cleared? Maybe leave some wierd "garbage" pixels?

If thats the case. Well I've had a similar problem with WebGL/OpenGL a year ago. Can't remember what my solution ended up beeing, but if I remember right I just created another thread and added the image to that.

Maybe the other guys have a better solution for problem :-)

My suggestion would be to use pointers to the textures instead.
This way you wont have these problems. You simple make the pointer, point to another texture.

Correct me if im wrong. But are you loading the image everytime you need a texture for a sprite? Thats a bad way of handling assets in general. Load all the textures/assets you need for the current scene into a array of some kind, maybe a map. When the scene is done, delete those textures/assets you dont need further to free up some memory and don't get alot of garbage.

What you want is called wordwrapping.
But here some code I made for you, that hopefully may help you get going

#include <fstream>
#include <sstream>
#include <list>
#include <SFML\Graphics\Text.hpp>
#include <SFML\Graphics\Rect.hpp>

int main()
{
        std::string line;
        std::ifstream file;
        std::list<sf::Text> textList;
        sf::Text text("", font, 50); //Load your font and replace 'font'


        file.open("text.txt"); //Set your path here
        if(file.is_open())
        {
                while(std::getline(file, line))
                {
                        //Getting every line of the .txt file and putting it in the 'line' string
                        text.setString(line);
                        textList.push_back(text);
                }
        }

        float i = 0;
        for(std::list<sf::Text>::iterator it = textList.begin(); it != textList.end(); ++it)
        {
                sf::Text& text = *it;
                sf::FloatRect boundings = text.getLocalBounds();
                text.setPosition(0.f, i * (boundings.height + 5));
                ++i;

                //draw or something here
        }
}

(craft.ThrustActive - craft.ReverseActive * 0.5)

Maybe you have to mulitiply with delta here somehow.

Can you please provide some code?
Because it should be easy to implement with a simple stream.

First: You should NOT initialize your class members in the header file.

Second: Did some testing after some modification for making it working with visual c++. So it making me wonder, does your code compile at all? After I did get your the code compiled, I got no crash. hmmm...

Please don't link this way, it is not cross platform and writing non cross platform code is a very bad habit once started.

I know that it is non-cross platform and I noramlly don't link that way. But thanks for reminding me.

Like Jesper said, use the std::to_string.

sf::Text text;
sf::String str = std::to_string(123);

//add font and stuff

text.setString(str);

Oooh, I just missed a library ... stupid me!

#pragma comment(lib, "ws2_32.lib")

Network / Unresolved external from static library Visual Studio 2013

« on: March 18, 2014, 10:28:28 pm »

Hi!

I've upgraded my visual studio to 2013 lately and have been recompiling the libraries.
Everything have been working like a charm, untill i tried to use a class from the network library ... 

I'm linking it correctly with "sfml-network-s-d.lib", "SFML_STATIC" and so on..

I get no error compiling SFML in Visual Studio 2013.

I dont have a log on this computer, but i it's just ALOT of unresolved externals. Nothing about "__declspec(dllimport". Its like the whole static library is broken, but the library is being compiled without any error.

Anyone who have a idea whats wrong? The only idea I have right now is going back to Visual Studio 2012 and use the precompiled libraries.

UPDATE:

Here is a simple test code

#include <SFML\Network.hpp>

int main()
{
        sf::TcpSocket socket;
        return 0;
}

Here is my log
