SFML projects / New version released!

« on: November 28, 2011, 11:52:42 pm »

Update: v.1.3.2alpha released!

Changes made in latest version:

• Now you can see 100 scores in the high-score screen, not only 10 (use arrow keys to browse)
• Pressing the ESC key while playing, do not exit the game, but cancels it.
• Pressing the window close button exits the game also in high-score screen.
• Pressing the ESC key while writing player name doesn't save the score to leaderboard.

That's a really nice and original little game! The concept is very challenging.

The program runs fine under Linux with wine.

Thanks for the positive comment. I'm happy you like the concept!

Minor bug: it seems like sf::Event::Closed is not handled in the Online High-Scores menu.

It's a known issue, for sure I'll fix it in the next version together to other minor bugs. I'm planning to put an high-score with more positions shown in different pages, where you can browse the leaderboard with arrow keys.

PS: Eh? No Ninja? :x

I'll soon release a new version of Falling Rocks with online leaderboard.

not yet, but I expect to do so in the future.

I definitively love your games

How do you manage the online highscores ?

I'm happy you like them!
For online hi-scores I use:
Server side : a PHP/MySQL solution in a free web hosting site
Client side: sf::Http class from sfml network package.

Your game is well made. Sometimes I don't know which keys will move the ball in a desired way.

Thanks for your comment, teri!
Anyway, I was convinced that the controls were very intuitive.
I recommend you to use left/right keys when the line is horizontal and up/down when it's vertical, to avoid confusion.
Maybe it's just a matter of getting used to the controls.

This game was present at a game jam event in Milan (April 16th-17th 2011): "Lunarcade Factory: Lines". ( link )
I've made some changes since then.
The most important thing is that I have added a leaderboard online, so you can compete with other remote players.
The game have a simple mechanic: you have to survive as long as possible, jumping from a line to another. Jumps can be done when the little sphere is at the intersection of two lines.
Lines fall down from the top of the screen and the game is over when the player touch the bottom of the screen.
I used SFML 1.6 to do all graphics, using sf::Shape class.
Special thanks to posva who gave me some helpful tips to create the online leaderboard.

Controls

arrow keys = move the sphere
L-CTRL or Z = jump from a line to another one
M = Mute
P = Pause game
H = Display online high-scores
S = Save current score to online leaderboard
F4 = Toggle Fullscreen mode

General / Sprite movement

« on: November 13, 2011, 11:08:20 pm »

Thanks a lot for your help.It works now but I had to devide my GetFrameRate() / 200 to get it right. One more question if you don't mind. It pauses when I change directions is there something I can do about that?

There is another way to handle inputs continuosly (without waiting for a key will repeat if held longer).
In sfml 1.6 you could use, for example:

Code: [Select]


App.GetInput().IsKeyDown(sf::Key::Right)

I don't know how to do it on SFML 2. :/

I am using sfml2

In that case use:

Code: [Select]


App.EnableVerticalSync( true );

Thanks that worked but the movement is choppy is there a way to fix that?

Try (if you're using sfml1.6):

Code: [Select]


App.UseVerticalSync(true);

where App is your rendering window.
This command limits framerate to vertical refresh of your current video mode.

Pay attention to the structure of your switch statements.
You have 2 levels of switch (they are nested), so you have to write the correct code.
Try this!
(I highlighted with an arrow the lines I added)

Code: [Select]


float ElapsedTime = Window.GetFrameTime() ;
       
        // Move the sprite
        switch(Event.Type)
        {
        case sf::Event::KeyPressed:
            switch(Event.Key.Code)
->          {
                case sf::Keyboard::Left:
                    Sprite.Move(-100 * ElapsedTime, 0);
                    break;
                case sf::Keyboard::Right:
                    Sprite.Move( 100 * ElapsedTime, 0);
                    break;
                case sf::Keyboard::Up:
                    Sprite.Move(0, -100 * ElapsedTime);
                    break;
                case sf::Keyboard::Down:
                    Sprite.Move(0,  100 * ElapsedTime);
                    break;
                default:
                    break;
->          }
->          break;

->      default:
->          break;
        }


Another hint: 0 and 100 are considered integer numbers from compiler, use 0.f and 100.f instead, 'cause ElapsedTime is a float.

General / Re: Custom Icons in SFML?

« on: November 13, 2011, 02:29:38 pm »

Is there a way to change the window icon from the default icon to a custom .ico image on a window created by the sf::RenderWindow class, like you can with a Win32-made window?

You have to create a .rc file and then import it in your project.
This is the code:

Code: [Select]


IDR_APP_ICON ICON "(.ico filename)"
GLUT_ICON ICON "(.ico filename)"

General / Using SFML 1.6 under Ubuntu 11.10

« on: November 12, 2011, 10:52:52 pm »

Hi, all! I'd like to compile my games (with SFML 1.6 code) under a linux OS.
I installed Ubuntu 11.10 distro on my laptop and then Code::Blocks.
I downloaded also SFML 1.6 SDK and install it on the system with "sudo make install" command.
I configured the IDE to work with them (linking libs dinamically), but I obtain this error:

Code: [Select]


compiling: main.cpp
/home/ubuntu/Documents/CodeBlocks projects/ProvaLinux/ProvaLinux/main.cpp:1:27: fatal error: /usr/local/include/SFML/System.hpp: Permission denied
compilation terminated.

 
Does someone know how to configure SFML to work under CodeBlocks?
I'm a very beginner with linux OSs. :/
