General / A few questions regarding Android development

« on: November 01, 2014, 07:13:14 pm »

I want to start developing C++ Android applications using SFML.
Unfortunately, I don't have any experience developing apps for the Android platform, so I have a few(a bunch of) questions:

• Do I have to modify my existent C++ code to compile it for android?
• What else do I have to include to my project? (Maybe a manifest file?)
• Can I use sort of an Android API in my C++ project? (For example to get the screen resolution of the device)
• How do I compile my C++ code?
• Can I continue using my favorite IDE?

If somebody has the time to answer my questions or just give me a link to a website or forum topic which helps me, I would really appreciate it!

Today I built SFML from the latest GitHub source on my Win7 PC, and It also had the space on top of the text. I guess my problem is solved now, since my code won't provide different results depending on the operating system anymore!

Okay, its not the fault of libsfml-dev.
Today, I installed a fresh Arch Linux (x86_64), and It doesn't work. I built SFML from GitHub master with cmake.
The libraries

extra/freetype2 2.5.3-2

and

extra/libxft 2.3.2-1

were already installed (maybe they are dependencies of cinnamon).

I honestly have no idea what I could do to solve the problem

Does somebody have an idea?

So... what happens if you do exact same, except instead of installing libsfml-dev, you grab the latest GitHub master, build it and install it? If it produces the correct results, then libsfml-dev is bogus.

It works perfectly, theres no space on top. Tested with a fresh Mint VM without updates. After I installed SFML in the usr/local directory, the example program didn't start, and showed me an error message that it couldn't find the SFML library, which is weird, since I linked it statically. Then I installed SFML in the root directory and it worked.
I had libsfml-dev installed  before I built SFML from source on my original system, but removed it before I started building the library (apt-get remove libsfml-dev and apt-get autoremove, I forgot to simply use purge).
So I guess that libsfml-dev was/is causing the error.

I've set up a VM with Linux Mint, and I'm able to reproduce the problem. I didn't install any updates on the virtual machine, and I only installed the packages cmake-gui, libsfml-dev, codeblocks and g++.
I copied the CB project folder to my wm and compiled the code; it showed me the same results as on my original system.
Now I will build the bugfix branch and try to compile it without code::blocks...

Okay, so I checked the Sha1 sums of the fonts, they seem to be the same as yours:

2c078150376bc66e2a4a20ffa6bbbe7a5c03e752  Facile Sans.ttf
723ce6489b30fed829e7763db700d50dfc4e26c1  Facile Sans.otf
 

Here is a screenshot of the Synaptic Package Manager, I searched for "libfreetype". It looks like I have the same libfreetype version.

Again, here is the code I used:

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

using namespace std;

int main()
{
    sf::RenderWindow window(sf::VideoMode(500, 500), "Example");
    sf::Font font;
    font.loadFromFile("Facile Sans.ttf");
    sf::Text text;
    text.setFont(font);
    text.setPosition(0, 0); // (0, -20) looks good
    text.setCharacterSize(84);
    text.setString("Text");
    text.setColor(sf::Color::Black);
    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        }

        window.clear(sf::Color::White);
        window.draw(text);
        window.display();
    }

    return 0;
}

 

I use the bugfix/font_fix branch of SFML. (https://github.com/SFML/SFML/tree/bugfix/font_fix)

I hope this helps. If you need more information, just ask for it.

Graphics / Re: Render special characters from a variable

Thanks
I tried to get the character as a char and then append it to a std::string at first, but now it works perfect.

Graphics / Render special characters from a variable

« on: September 21, 2014, 04:16:32 pm »

I want to render a sf::Text, which contains special characters.
I know that if the text wouldn't be a variable, I could do somenthing like this:

text.setString(L"öüäßê");

But in my case, the text is entered by the user.
How can I render the sf::Text, without having to use a switch statement to check if the character the user entered is a special one?

Yes, I'm using freetype version 2.5.2.
And I also think that the Linux version is bugged, unless the space on the top is a specific problem of the font. But I'll see how it looks on Windows after the supplied freetype has been updated.

I found out that the dimensions of the text also are different:
Dimensions on Linux:       left:  0 top:  19  width:  207  height: 65
Dimensions on Windows:  left: -1 top:  -2  width:  209  height: 66
Code used to get the dimensions:

    sf::FloatRect rect = text.getLocalBounds();
    cout << endl << "Width: " << rect.width << " Height: " << rect.height << " Top: " << rect.top << " Left: " << rect.left;

And to achieve the look from windows on linux, I had to set the position of the text to 0, -20 .

I don't use Fedora Linux but Linux Mint 17, which bases on Ubuntu 14.04. Which version of the freetype development files have you installed?

I uninstalled SFML from my Linux OS and compiled the branch. The git command I used to get the code was

git clone -b bugfix/font_fix --single https://github.com/SFML/SFML.git

I hope this command got me the right repository, I don't know much about git.
The Example Program compiles fine, but the result is still the same 
Any other ideas?

Graphics / sf::Font size not accurate

« on: September 19, 2014, 06:00:19 pm »

Hey guys! It has been a while since I have been around on the forum. But now I'm back with a question:

I recently have been developing stuff under Linux. When I was working with Fonts, I noticed that the font size isn't accurate; I had to move the font to achieve what I wanted. Then I compiled the same code under Windows and It looked weird, because the font size was right. I also noticed that this doesn't happen with every font.

Example:
I compiled the following code under both operating systems(I used the font facile sans):

#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode(500, 500), "Example");
    sf::Font font;
    font.loadFromFile("font.ttf");
    sf::Text text;
    text.setFont(font);
    text.setPosition(0, 0);
    text.setCharacterSize(84);
    text.setString("Text");
    text.setColor(sf::Color::Black);
    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        }

        window.clear(sf::Color::White);
        window.draw(text);
        window.display();
    }

    return 0;
}
 

This is how it looks under Linux:


Under Windows:


Does anyone know why this happens and how to fix it?
I appreciate any help

Great news!
I'm sure SFML will grow faster now

Apart from the fact that this question doesn't have much to do with my problem:
Yes, my code is based on the one from the tutorial mentioned by Jesper Juhl
