SFML projects / Falling Rocks! (demo inside)

« on: February 02, 2012, 09:02:55 pm »

Very nice game.
I just got a score of 1585 in impossible.

Apparently it's not for windows only: it runs perfectly on my linux with wine.

Good!! Anyway I'm working to release a linux native version.
Potentially I can release a MacOS X version, too! But I haven't a Mac. :'D

Really fun game, you should develop it for the iphone or ipad

Great game! gj!

yeah you should export your project on android and ipod/iphone..!
at  cost<1€ you become richest!

I think it's a good idea!
I'm running to download Android and iOS SDKs!

Yeahhh I beat the game!
A very interesting surprise at the end of the game!

The game is awesome!!
I finish the game with a bad ending.. :/

SFML projects / COSMAGERS - new 2D MMORPG developing

« on: January 22, 2012, 01:53:33 pm »

I can't try the game, cause of the low-resolution of my screen! Some buttons disappear out of the screen..
My screen resolution is 1366x768.
Window resizing doesn't work properly. :/

Graphics / Sprite Movement on Single MouseClick

« on: January 17, 2012, 10:14:52 pm »

How would I update the Destination and Distance vectors then?  Because doing:

Code: [Select]

Destination = (NewX, NewY);
Doesnt work (error).  And I can not find any other commands in the documentation that would allow for the vector to be updated within the if statement.

The right code is:

Code: [Select]


Destination = sf::Vector2f (NewX, NewY);


Additionally, I think you have to check events for mouse inside the while statement, instead of using App.GetInput() method, cause they have a different behavior.
App.GetInput().IsMouseButtonDown() returns true continuously untill you release the button.
App.GetEvent() returns a true value only at the moment you press the button.

Graphics / Sprite Movement on Single MouseClick

« on: January 07, 2012, 12:00:11 am »

I think you have to normalize  the "destination - origin" vector, that is the movement direction vector, on mouse click, with a code like this:

Code: [Select]


sf::Vector2f direction = Destination - Origin;
// calculate distance between origin and destination points
float distance = sqrt( (Destination.X - Origin.X) * (Destination.X - Origin.X) + (Destination.Y - Origin.Y) *  (Destination.Y - Origin.Y) );
// vector normalization (you obtain a unit vector = vector of lenght 1)
direction /= distance;


At each loop you could move your player sprite with:

Code: [Select]


Player.Move ( direction * speed );


So you have a movement not-dependent from distance.
You have also to manually check when sprite reach the destination point (within a certain error margin)

General / Gameloops and timing, smooth rotation

« on: December 13, 2011, 08:27:51 pm »

Let VSync decide the FPS of the game.
Enable window vsync and use GetFrameTime function to obtain smooth movements and rotations. It works!

General / Code::Blocks & Windows XP libgcc_s_dw2-1.dll

« on: December 13, 2011, 07:35:00 pm »

In Code::Blocks I use this linking options:

Code: [Select]

-static-libgcc
-static-libstdc++

to avoid libgcc_s_dw2-1.dll dependence.
This is the way to static link gcc libraries.

SFML projects / Linavalanche

« on: December 09, 2011, 05:01:56 am »

Update: v.1.3.3alpha released!

Changes made in latest version:

• Leaderboard access is now in a separated thread. This avoids the game to freeze when connecting to server to retrieve hi-scores.
• Lines change to a white color on change. This makes it easier to find the colored lines (that give bonus on change) to get higher score.
• F4 toggle fullscreen mode

General / Can sfml classes be serialized?

« on: December 03, 2011, 12:14:13 pm »

XML is serialization. It's just an output format -- other formats could be binary data, JSON, INI, ...

With a well designed library (such as boost.serialization) the serialization functions and the output format are completely separated. You only have to write your serialization functions once, in a generic way, and then you can output the result to many different formats.

Your remark is fully correct!
In my previous post with "serialization" I mean binary serialization, and with "using xml" I mean "using xml serialization without boost"

Graphics / Partially drawing/hiding a sf::Shape::Line

I think best solution is to calculate the intersection between the lines and the edge of the map display.

Boost.Serialization doesn't enforce class modifications. For a non-intrusive serialization function, look at the documentation. Absolutely no need to modify SFML.

I knew that there was this non-intrusive method, but I preferred xml for simplicity (I've been using it for a while).
Anyway serialization could be my next choice.

Everything that is relevant to serialize is public, so why would you need to modify SFML itself?

Probabily it's possible, but I dont know how.
So I used xml documents.

I don't see why this should be complex, either. Just provide the global function overloads required by Boost.Serialization.

How can I access a sfml function and override it? With a derived class?
Or maybe I don't understand what you want to mean...

Maybe this will help:
http://www.boost.org/doc/libs/1_48_0/libs/serialization/doc/index.html

I tried to use serialization with boost, but the simplest way to implement it in your program is to modify sfml code itself. I think there's a complex way to do serialization without modify sfml code, but IMO it doesn't worth it.
I suggest to use xml instead.
I use tinyxml lib to save/load my sfml objects.
