Window / How use sf::Event::TextEntered in place of Event::KeyPressed
« on: October 04, 2011, 03:12:28 am »
For text input it's recommended to use TextEntered. But how do I enable the use of TextEntered? If a key is pressed the event received is keypressed. I want to receive textentered only in some cases. Most of time I want to receive keypressed, but when textinput or textarea is selected I wanto to receive textentered.

When I scale the image, only the center is totally scaled. The corners isn't scaled, the horizontal edges is scaled by x factor only and the vertical edges is scaled by y factor only.
How can I make this? Using a class with 4 sprites(one for center, one for corners, one for vertical edges and one for horizontal edges)? :?  :?:

General / About SFML version 2
« on: September 15, 2011, 02:32:14 am »
I want to know about SFML2. What are the main changes from the previous version 1.6?
  From what I understand today, sf::String now is called sf::Text and the current sf::String is to handle strings, now drawable texts. sf::Image   still represents a bitmap, but sf::Texture is used for rendering and is armazened in gpu memory.
  Am I right? And about performance? What was improved?
  Is it recommended to use sfml2 or is better I continue using sfml1.6? I see many projects like Thor and Sfengine using SFML2. Is it stable enough?
Speaking of which, I remembered Thor. When I would use the previous version, you could not sar Thor. But I'm thinking of using this version, so I'll learn how to work in thor. Mainly because she has a nice particle system. The system of particles Spark is also good, but difficult to configure it in linux.

Graphics / Just to be sure. Does SFML use OpenGL for render shapes?
« on: September 03, 2011, 07:10:40 pm »
Title says all. I'd like to use OpenGL or SFML to make vectors shapes. This shapes will be used in UI in my game. I thought about using cairo, but the performance is slow. Will be each line in a shape a call to glVertex?

Window / Adjusting window to screen format
« on: July 14, 2011, 03:45:29 am »
I want to make a game in fullscreen mode. And this game can to be played in normals or in wide screens. The game is a side-scrolling game. If the monitor is a widescreen(16:9), the game will display a larger map area. And if is a normal screen(4:3), the game will display a smaller area. In SDL I can to use SDL_ListModes() for list which modes are supported in gamer's screen. I want to do this in sfml. I want to list supported resolutions for choose one in this list. SDL_ListModes() returns a array of Rects. Rect->h and Rect->w is a supported resolution.
