« on: September 18, 2012, 06:30:26 pm »

I am trying to save player data to a txt file in the follownig format, but the problem is that i dont know how to save a single stat(ex. playerclass), and i dont know how to load into variables. Help!!

void Engine::SaveCharacterData(string PlayerName, int PlayerGender, int PlayerClass, int PlayerSkin)
{
    ofstream myfile ("Player1.txt");
    if (myfile.is_open())
    {
        myfile <<"Name:"<< PlayerName;
        myfile <<"Gender:"<< PlayerGender;
        myfile <<"Class:"<< PlayerClass;
        myfile <<"Skin:"<< PlayerSkin;
        myfile.close();
    }
    else
        cout << "Unable to open file";
}

void Engine::SaveCharacterClass(int PlayerClass)
{
    string curLine;

    ofstream myfile ("Resources/Saved_data/Player1.txt");
    if (myfile.is_open())
    {
        getline(myfile, curLine);
        if(curLine == "Class=")
        {
            myfile << PlayerClass;
        }
        myfile.close();
    }
    else
        cout << "Unable to open file";
}

@Tex Killer

That made my map look just like mine, just that every tile picture is messed up but the general look is alright.
It seems it cuts the sprite wrong, strange since when i tried without margins and spacing it worked.

Heres the picture:

Margins-Spacing vary for each tileset. Since this loader can load only one tileset margins-spacing are always the same(in a certain map). Margin-spacing are the ones from the image.

What i (walker) do here is load the tileset in to image apply a mask and then load it into a texture that loads in a sprite which is then being cut with this:

//Columns and rows (of tileset image)
    int columns = tilesetTexture.getSize().x / tileWidth;
    int rows = tilesetTexture.getSize().y / tileHeight;

    std::vector <sf::Rect<int> > subRects;//container of subrects (to divide the tilesheet image up)

    //tiles/subrects are counted from 0, left to right, top to bottom
    for (int y = 0; y < rows; y++)
    {
        for (int x = 0; x < columns; x++)
        {
            sf::Rect <int> rect;
            rect.top = y * tileHeight;
            rect.height = y * tileHeight + tileHeight;
            rect.left = x * tileWidth;
            rect.width = x * tileWidth + tileWidth;
            subRects.push_back(rect);
        }
    }
 

Here you can see that it only cuts by the number of columns and rows, it doesnt take margins and spacing in account.

I hope i helped.

Here is the SFML 2 version, works just like the 1.6.

Here it is, converted for sfml 2, everyone who wants can use it.

Margins exist on top, and on the left.
Spacing exists between every tile(not picture) which is defined with the width and height.

Both are integers.

level.h

level.cpp
http://pastebin.com/U1NG8eKD

This is written by Walker for sfml 1.6:

I know VertexArrays are better for situations like this, but im inexperienced and will use this for now until i get some knownledge.

Graphics / Trouble adding spacing and margin to Tiled map loader

« on: September 09, 2012, 04:13:08 pm »

I took "Tiled Map Loader" from Walker which is 1.6 and converted it to sfml 2. Works perfectly but now i want to implement spacing margin of the tileset.

int columns = tilesetTexture.getSize().x / tileWidth;
    int rows = tilesetTexture.getSize().y / tileHeight;

tilesetTexture is obviously the texture i loaded my tileset image into.
Now i should somehow add spacing and margin into consideration.

I managed to load spacing and margins from xml file into two variables: spacing, margin. But how to implement them into the calculations ? Somekind of for loop ? Plz show me how.

I can remove the problem by return 1 instead of Handle Click(position);

return HandleClick(position);

Where is the problem ?

General / Cant compile release mode

« on: May 16, 2012, 09:03:33 pm »

I was doing everything in debug and then i saw some topic where laurent says that the release mode is faster so i changed everything to release mode.
(removed the -d from libs, set the include and lib folder again)
 
Everything would work normally if i didnt have tinyxml but i have it:

Graphics / SetDrawingBounds help

« on: May 13, 2012, 12:21:55 pm »

I was working on Tiled system, and i managed to convert it to 2.0, but now the only problem is

Code: [Select]

Level level;
level.LoadFromFile("Maps/spawn.tmx");

sf::FloatRect rect2(0, 0, 2048, 1536);
level.SetDrawingBounds(rect2); // THIS

The tutorial said differently:

Code: [Select]

Create an instance of Level.

Level level;

To load a map file,

level.LoadFromFile("example.tmx");

You MUST set drawing bounds before attempting to display the level.

level.SetDrawingBounds(somesfview.GetRect());

I recommend using an sf::View to "scroll" the map, rather than moving the map itself. This way you don't have to worry about objects (NPCs etc) on your map moving (or not) correctly.
You will find you need to implement some system to only move the view by whole numbers, otherwise you will see gaps between tiles.

Then to draw you simply pass your renderwindow to the Draw function.

level.Draw(window);


Can someone write me with sf::View ? I dont know how to since there isnt a GetRect() anymore.
