SFML projects / Circle Patterns

« on: August 22, 2014, 03:32:20 am »

Hi guys.

I just finished to upload a video about my latest project - Circle Patterns.
Some time ago I already presented you my Spirograph and I think the circle patterns now look even better.

Take a look at the project:

SFML projects / Spirograph

« on: April 14, 2014, 09:47:57 pm »

In the last two days I programmed a little spirograph made in C++, SFML.

For now I can't show you my code, because it's looking awful, but I made a little video of the spirograph in action. Please forgive me for the bad quality, it's my very first video and I just made it in 5 minutes.




If somebody wants to see the code just tell me and I'll put it on github after refactoring.

Graphics / Drawing all vertices of a line to a sprite

« on: April 14, 2014, 07:09:36 pm »

The subject should already tell you what I want to know.

For reasons of performance, the lines can't be stored on vectors to draw them later, so I need to draw all points of a line to a sprite.
How am I supposed to do that?

Thanks.

Graphics / Exception while pushing back a sf::Text with sf::Font

« on: April 10, 2014, 08:14:09 pm »

Hello.

My current code to draw a button looks like this:

namespace foo
{
 std::vector<std::pair<sf::Text, sf::RectangleShape>> buttons;
 void newButton(...)
 {
  sf::Font bla;
  bla.loadFromFile("...");

  sf::text blub;
  blub.setFont(bla);

  buttons.push_back(std::make_pair(blub,  rectangle));
  //I think i can leave the rectangle-initialization out, because this works fine
 }
 void drawButtons(sf::RenderWindow &window)
 {
  for(std::pair<sf::Text, sf::RectangleShape> b : buttons)
  {
   window.draw(b.second);
   window.draw(b.first); //It fails here, because I set the Font
  }
 }
}
 

What I'm doing wrong? Obviously I'm not supposed to add the font before pushing it on a vector, but I need the font set[complet size of the sf::Text] for the rectangle-initialization.

SFML projects / My little collection to short SFML Code

« on: April 09, 2014, 06:07:40 pm »

Hello.

I recently made a little collection of functions which make my life with SFML easier.

SFML is my favorite library for graphical purposes, but I always wondered why there has to be so much code just to create a colorful rectangle or whatever so I decided to create a little library that helps me being faster.

Here you can find the SFMLib: https://github.com/4B/FuncCollection/blob/master/SFMLib.hpp

Feel free to give any suggestions and please tell me if I did something wrong.



Edit:
I forgot to talk about the name. Of course it won't be named as "SFMLib" if there will be a release one day. It's just a codename.
