sfml-tmxloader's Issues

layer->tiles doesn't give tiles from layers

Hi, correct me if I'm wrong but shouldn't following code return back a vector containing the map tiles?
Or how can I get the information of the tiles in a layer from a map?

for (auto layer = map.GetLayers().begin(); layer != map.GetLayers().end(); ++layer)
{
    if (layer->name == "fooLayer")
    {
       tmx::MapTiles fooTiles = layer->tiles;
       std::cout << "FooTiles = " << fooTiles.size() << std::endl;
       // result is size = 0
    }
}

Strange culling

The half of isometric map is always invisible (x direction). And culling by x is also not working.

This map in Tiled: http://i.imgur.com/S7vfCE3.png

Object visibility property has no effect

This is caused by having all tile type objects drawn via a vertex array. The possible solutions would be to either go back to using sprites for tile objects, or providing an interface for attaching sprites to objects, so that an object layer can be made invisible and sprites drawn at will

proper parsing of tileset images

currently tileset images and tsx files are required to be in the same directory as the tmx map file. Paths should be properly parsed, both relatively and globally, so that images can be stored as the user requires. At the very least a proper descriptive error should be thrown when a path is not recognised.

Please add a Default Constructor that takes no addSearchPath() in Map Loader Class

I would like to see this added to map Loader

class MapLoader final : public sf::Drawable, private sf::NonCopyable
{
public:
MapLoader();
MapLoader(const std::string& mapDirectory);

in maplaoderpublic.cpp

//ctor
MapLoader::MapLoader()
: m_width(1u),
m_height(1u),
m_tileWidth(1u),
m_tileHeight(1u),
m_tileRatio(1.f),
m_mapLoaded(false),
m_quadTreeAvailable(false),
m_failedImage(false)
{
//reserve some space to help reduce reallocations
m_layers.reserve(10);
}
MapLoader::MapLoader(const std::string& mapDirectory)
: m_width (1u),
m_height (1u),
m_tileWidth (1u),
m_tileHeight (1u),
m_tileRatio (1.f),
m_mapLoaded (false),
m_quadTreeAvailable (false),
m_failedImage (false)
{
//reserve some space to help reduce reallocations
m_layers.reserve(10);

AddSearchPath(mapDirectory);

}

Thanks Matt!

I followed your guide on the wiki and got everything to work perfectly, I created a demonstration with a portable (machine independent) Visual Studio project/Demo here that can be used as a template for anyone who downloads the project along with a demonstration of how the camera can be used to traverse the TMX maps. Along with that I added a built version of Zlib for the x86 architecture to the project for people who have trouble building it. Thanks for all the help and i would love it if you left a link to the template in your project description ;).

Best Regards!

PS: I will add a readme tommorow!

Please add functions to return map tiles' width and height

//returns tile width in pixels
sf::Uint16 GetTileWidth() const;
//returns tile height in pixels
sf::Uint16 GetTileHeight() const;

sf::Uint16 MapLoader::GetTileWidth() const
{
return m_tileWidth;
}

sf::Uint16 MapLoader::GetTileHeight() const
{
return m_tileHeight;
}

Add z-order depth calculation for non-tiled sprites

When creating rpg style maps and drawing sprites such as players or NPCs, z-ordering needs to be implemented to that sprites are correctly drawn in front of or behind scenery

Visual Studio Compatability issues

I'm having difficulty using your libraries with visual studio 2013, can you possibly add a tutorial to the description or a link on how to integrate your libraries to a visual studio project?

Best Regards.

Linker error

I have a few linker errors (they are here):
http://www.gamedev.net/topic/670937-sfml-tmxloader-issues/

Not sure if I'm supposed to have any .lib files but at the moment I dont. Can't figure out why else it wouldn't be working.

Simple test fails: call for help

Hello user of sfml-tmxloader,

Both sfml-tmxloader and STP do not work anymore on a standard Tiled map. I suspect something upstream changed, but I have no clue.

Anybody has an idea?

I have created a test case on my fork. It loads a standard tiled map and checks that the number of layers is non-zero. It fails on that assert.

The test can be run with:

cd tests
./test.sh

@fallahn notified me of his full schedule, so who else can help me with pugixml?

I also submitted the same test to STP, that suffers the same problem, as a Pull Request, so I assume if one fixes the bug, it will be easier for the other to follow.

When the test is fixed on my fork, the Pull Request for fixing this bug can be accepted.

Thanks, Richel

Cmakelists line 129

there is a problem there, the previous cmakelists didn't cause any errors of this type, it is about pugi

Please add functions to return map tiles' width and height

//Get tile width
sf::Uint16 GetTileWidth();
//Get tile height
sf::Uint16 GetTileHeight();

sf::Uint16 MapLoader::GetTileWidth()
{
return m_tileWidth;
}

sf::Uint16 MapLoader::GetTileHeight()
{
return m_tileHeight;
}

Terrain Tiled tmx load

Hello, thank you for your hard work. I Have been trying to load a map with Terrains but the loading always fail. Are terrain supported ? if yes I think it is a bug.

Add debugging levels for console output

I've found the debug information useful at the beginning, when my objective was to develop a basic structure of the game and get the map to load, but now it's making the debugging process more difficult. I get about 400 lines per map load, which requires a lot of scrolling to get to the beginning.

My suggestion to improve this is to split the messages up into debug levels. The user can set the debug level using a static variable and only messages with an equal or higher score get shown.

VS2013 Project error not generate .libs

I selected in cmake shared libs dlls, at build the vs project, but at compile, the examples and drop an error of no find .lib files of tmx-loader or pugi (in release mode x32)

"Collection of images" tileset type

First of all, thanks for the awesome library!

Now, the problem :p
The tmx format (and Tiled) provides another way of loading sprites: using collection of images.
This results on the following code being added to the final tmx file:

 <tileset firstgid="65" name="images" tilewidth="44" tileheight="42">
  <tile id="0">
   <image width="44" height="42" source="../sprites/image1.png"/>
  </tile>
  <tile id="1">
   <image width="44" height="42" source="../sprites/image2.png"/>
  </tile>
  <tile id="2">
   <image width="44" height="42" source="../sprites/image3.png"/>
  </tile>
 </tileset>

But when loading this with sfml-tmxloader, I'm getting this error: Missing image data in tmx file. Map not loaded. (found on https://github.com/fallahn/sfml-tmxloader/blob/master/src/MapLoaderPrivate.cpp#L191)

Any thoughts on this?

Quadtree broken?

All objects in the quadtree are at the topmost level despite being trivial to partition, except for one object which cannot be found in the quadtree at all for some reason.

I can provide the TMX.

Only first created layer get rendered

Hi, guys! Thanks for your work!

I started using your loader and faced an issue with rendering multiple layers.
Basically when i add more than one layer

i see that sfml-txloader keeps rendering only one layer on scene:

I compiled project with logging and log looks fine either:

INFO: Caching image files, please wait...

Could you please advice how to get all layers be rendered?

Add support for animated tiles

It would be nice to eventually add support for animated tiles. This isn't a feature in Tiled so would need some serious consideration as to how animated tiles would be designated in the editor. Overall this feature is low priority but I would love input from anyone who has ideas about how this could be done.

Map objects not of tile size are offset

The offset added with https://github.com/fallahn/sfml-tmxloader/blob/master/src/MapLoaderPrivate.cpp#L916 messes up map object placement, displacing objects down if their images are not tile-sized. Commenting it out fixes it, but I'm not sure if that might break something else.

Give more control over quadtree elements

Hi. Thanks for this awesome library. Having a map loader with a built-in quad tree is really convenient. It would be nice to have more control over the quad's elements, though.

For instance, I'd like to be able to only add objects from a particular layer instead of all layers (or arbitrary combinations of layers/objects). I suppose I can do this now by using QuadTreeRoot directly, but I'd be ignoring the UpdateQuadTree and QueryQuadTree methods, which aren't strictly necessary.

Also nice would be using the quad tree class for anything providing a GetAABB method, not just Map Objects. For instance, I'd love to double dip and use it for tracking projectiles, for instance.

I think both of these can be resolved by breaking out the quad tree implementation into a template. It's arguable whether or not the MapLoader member functions should remain or be removed in favor of using the QuadTree directly.

What do you think?

No compatibility with AnimatedSprite class?

Hi!
I'm new using TMXLoader, but what an incredible tool !
I'm also using AnimatedSprite class : https://github.com/SFML/SFML/wiki/Source%3A-AnimatedSprite
And here is the problem : Whenever I load a" tmx" map and more precisely whenever i draw it, I am no longer able to see my animated sprite on the screen, while in the meantime, I am able to see classics sprites...

Here's my code :

include <SFML/Graphics.hpp>

include <tmx/MapLoader.h>

include "AnimatedSprite.h"

include

int main()
{
// setup window
sf::Vector2i screenDimensions(800, 640);
sf::RenderWindow window(sf::VideoMode(screenDimensions.x, screenDimensions.y), "TMXLoader");
window.setFramerateLimit(60);
sf::View view(window.getDefaultView());

// load texture (spritesheet)
sf::Texture texture;
if (!texture.loadFromFile("ressource/character/walk.png"))
{
    std::cout << "Failed to load player spritesheet!" << std::endl;
    return 1;
}

// set up the animations for all four directions (set spritesheet and push frames)
Animation walkingAnimationUp;
walkingAnimationUp.setSpriteSheet(texture);

Animation walkingAnimationLeft;
walkingAnimationLeft.setSpriteSheet(texture);

Animation walkingAnimationDown;
walkingAnimationDown.setSpriteSheet(texture);

Animation walkingAnimationRight;
walkingAnimationRight.setSpriteSheet(texture);

for (int i = 0; i <= 512; i += 64)
{
    walkingAnimationUp.addFrame(sf::IntRect(i, 0, 64, 64));
    walkingAnimationLeft.addFrame(sf::IntRect(i, 64, 64, 64));
    walkingAnimationDown.addFrame(sf::IntRect(i, 128, 64, 64));
    walkingAnimationRight.addFrame(sf::IntRect(i, 192, 64, 64));
}

Animation* currentAnimation = &walkingAnimationDown;

// set up AnimatedSprite
AnimatedSprite animatedSprite(sf::seconds(0.2), true, false);
animatedSprite.setPosition(sf::Vector2f(screenDimensions / 2));

tmx::MapLoader ml("ressource/maps");
ml.Load("prison.tmx");

sf::Clock frameClock;

float speed = 100.f;
bool noKeyWasPressed = true;

while (window.isOpen())
{
    sf::Event event;
    while (window.pollEvent(event))
    {
        if (event.type == sf::Event::Closed)
            window.close();
        if (event.type == sf::Event::KeyPressed && event.key.code == sf::Keyboard::Escape)

Unresolved external symbol

Using Visual Studio 2015, I can include the file MapLoader.h and plugixml.h just fine, but after adding tmx::MapLoader ml("maps\\"); the compiler crashes with this error:
Error LNK2019 unresolved external symbol "public: __cdecl tmx::MapLoader::MapLoader(class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &,unsigned char)" (??0MapLoader@tmx@@QEAA@AEBV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@E@Z) referenced in function "void __cdecl 'dynamic initializer for 'ml''(void)" (??__Eml@@YAXXZ)
Not sure what I'm doing wrong or if it's a bug :/

MapObject::Move is incorrect

moving the points as well as the centre point adds up to double the movement (the points are supposed to be relative)

Building Error (SFML/Graphics/VertexArray.hpp not found)

Hello,

I'm trying to build sfml-tmxloader on Ubuntu 14.04. I pulled the source code from the git repository, created a build dir, set the SFML_ROOT to the path and ran "cmake ..". Here are the results:

-- Found SFML 2.1 in /home/hiram/Desenvolvimento/sfml/include
-- Found ZLIB: /usr/lib/x86_64-linux-gnu/libz.so (found version "1.2.8")

Everything looks fine, but when I run "make" I get the following error message:

It's basically saying that SFML/Graphics/VertexArray.hpp was not found (it's in portuguese), although CMake previously informed that it was able to find the SFML dir.

Any clues?

Thanks in advance.

Rectangle objects may not always be parsed correctly

As per this thread

Draw only visible tiles

In void LayerSet::draw(sf::RenderTarget& rt, sf::RenderStates states)
function draws every tile, even when it's not visible.
rt.draw(&m_vertices[0], static_cast<unsigned int>(m_vertices.size()), sf::Quads, states);
I know that sfml propably won't draw tiles which are outside of screen, but even looping through every tile in layer slows down application when using large tilemaps. For example in my project FPS drop about 30% (140 FPS when map is 50x50 and 100 FPS when 200x100). I use tiled layer for background. I know that framerate is low, but i also use some demanding shaders.

Since tiles are always in grid, it wouldn't be very hard to use that property and draw only visible tiles (especially when tiles would be stored in 2D array/vector).

Animated Tile with Tiled Editor

Hi everybody,

I was wondering if there is a way to handle animated tiles as follow:
https://youtu.be/ZwaomOYGuYo?t=15m19s

Because when I add an animation, it is not shown as animated, so I guess it is not handle by the parser.

I've found this issue https://github.com/fallahn/sfml-tmxloader/issues/6
Unfortunately I've not found in which way Tiled add properties to an animated tile and how to get that property using the parser.

Do you have any idea?

I guess I have to get through all tiles and then check the property, if it is an animated tile, I just have to update the textureRect of the sprite to obtain the animation.

But what is the property for animated tiles?

Any help is appreciate 😄

Bug when adding another image layer to map

If another new image layer is added, then the previous sprite fails to show up (white square).

A reference to an element in a std::vector may become invalid when adding things to it, because the vector may need to resize itself and move to a different location in memory.

Doesn't work with SFML 2.2

Hello :)
I recently updated to SFML 2.2, but when I compiled my program to test it the map didn't show up. Si I tried with this minimal code:

#include <SFML/Graphics.hpp>
#include <tmx/MapLoader.h>

int main()
{
    sf::RenderWindow window(sf::VideoMode(640,480),"Test");
    tmx::MapLoader ml("assets");
    ml.Load("map.tmx");
    while(window.isOpen())
    {
        sf::Event event;
        while(window.pollEvent(event))
        {
            if(event.type == sf::Event::Closed) window.close();
        }
        window.clear();
        window.draw(ml);
        window.display();
    }

}

But that didn't work :/
I will try to download the 2.1 SFML (the changes don't really interests me), but it would be nice if for your library to be compatible with the new SFML :)

BodyCreator::Add fix

Hello,
It seems that box2d uses pixels in 2BodyDef.position.Set() method and this is why BodyCreator is broken. Every created body is placed at 0,0 coords so i modified this code to this(only changed the position setting stuff and conversion methods):

//conversion methods
b2Vec2 tmx::SfToBoxVec(const sf::Vector2f& vec)
{
    return b2Vec2(vec.x,vec.y);
}

    return sf::Vector2f(vec.x,vec.y);
}

float tmx::SfToBoxFloat(float val)
{
    return val * 0.02f;
}

float tmx::BoxToSfFloat(float val)
{
    return val * 50.0f;
}



b2Body* BodyCreator::Add(const MapObject& object, b2World& world, b2BodyType bodyType)
{
    assert(object.PolyPoints().size() > 1u);

    b2BodyDef bodyDef;
    bodyDef.type = bodyType;

    b2Body* body = nullptr;



    MapObjectShape shapeType = object.GetShapeType();
    sf::Uint16 pointCount = object.PolyPoints().size();

    if (shapeType == Polyline || pointCount < 3)
    {
        bodyDef.position.Set(object.GetPosition().x, object.GetPosition().y);
        body = world.CreateBody(&bodyDef);

        const Shape& shape = object.PolyPoints();

        }
    }
    else if (shapeType == Circle ||
        (object.Convex() && pointCount <= b2_maxPolygonVertices))
    {
        b2FixtureDef f;
        f.density = 1.f;
        bodyDef.position = SfToBoxVec(object.GetCentre());
        if (shapeType == Circle)
        {
            //make a circle
            b2CircleShape c;
            c.m_radius = object.GetAABB().width / 2.f;
            f.shape = &c;

            body = world.CreateBody(&bodyDef);
            body->CreateFixture(&f);
        }
        else if (shapeType == Rectangle)
        {
            b2PolygonShape ps;
            ps.SetAsBox((object.GetAABB().width / 2.f), (object.GetAABB().height / 2.f));
            f.shape = &ps;

            body = world.CreateBody(&bodyDef);
            body->CreateFixture(&f);
        }
        else //simple convex polygon
        {
            bodyDef.position.Set(object.GetPosition().x, object.GetPosition().y);
            body = world.CreateBody(&bodyDef);

            const Shape& points = object.PolyPoints();
            m_CreateFixture(points, body);
        }
    }
    else //complex polygon
    {
        //break into smaller convex shapes
        bodyDef.position = SfToBoxVec(object.GetPosition());
        body = world.CreateBody(&bodyDef);

        m_Split(object, body);
    }

    return body;
}

It does work almost perfectly but there is still one little problem with it though.

Non-contiguous tile IDs break rendering

If you have a collection of images as a tileset where you've deleted a tile from the middle, rendering breaks because sfml-tmxloader expects the IDs to be contiguous.

GetLayers() doesn't work as spected

Hi!
I'm trying to render each layer individually. For so I made this little function:

tmx::MapLayer Map::GetLayer(std::string layerName){
    for( int num = 0; num < ml.GetLayers().size(); num++)
    {
        tmx::MapLayer res = tmx::MapLayer(ml.GetLayers().at(num));

        if(res.name == layerName)
        {
            return res;
        }
    }
    return tmx::MapLayer(ml.GetLayers().at(0));
}

So im calling it like this:

m->mWindow->draw(GetLayer("Capa 1"));

And the result is a little square at the top of the window

When the layer is much bigger

I don't know if GetLayers() is supposed to work like this or not. Maybe is a bug?

Thank you so much!

PS: Im using gcc 4.8 on Windows, if that helps...

Can't draw map properly if it wasn't the the first one the maploader loaded.

Huge apologies if this is me missing something obvious. I'm not sure if this is an issue or if I'm doing something wrong.

When I load a map in the program for the first time like ml.Load("first.tmx"); it loads the map and draws it fine. But later on in the program, when I load another map to the same maploader like ml.Load("second.tmx"); and draw it, it will only draw the first 10x10 tiles from the top left.
e.g. first load: http://i.imgur.com/mS6lR3t.png?1
second load: http://i.imgur.com/SDJ0Noo.png?1

I'm not doing anything with SFML's views and the map is the same size as the window. Thanks for any help.

Laggy and doesn't draw all map?

I'm not sure why but the map is laggy and it only loads a portion of the map, here's my code:

#include "MapClass.h"

std::vector<sf::FloatRect> mapBounds;
tmx::MapLoader map("maps/");
std::vector<tmx::MapLayer> mapLayers;
sf::Vector2u mapSize;

MapClass::MapClass()
{
}

MapClass::~MapClass()
{
}

void MapClass::loadMap(std::string mapName, sf::RenderWindow &window)
{   
    map.Load(mapName);
    window.draw(map);
}

and I am drawing it like so in my main function:

map->loadMap("lvl1.tmx", window);

here is what it looks like when I run it

MapObject setVisible ?

Hi,
Since i'm newbie with TmxLoader, I dunno how it is supposed to work but :

for (auto& layer : layers)
{
    if (layer.type == tmx::ObjectGroup)
    {
        for (auto& obj : layer.objects)
        {
            if (layer.name == "Collectable")
            {
                if (obj.Contains(animatedSprite.getPosition()))
                {
                   std::cout << "Test";
                   obj.SetVisible(false);
                }
            }
        }
    }
}

I've got the "Test" text in my cmd, but the object is still visible on the map, I really don't know what to think about it?
If anyone has suggestions, it would be really appreciated ! :)

Debug info should be drawn for single layers

Currently the debug info can only be drawn for all layers, or no layer. It also incurs a dramatic performance hit. This could be updated to allow drawing of debug info per layer, and performance increased with the use of vertex arrays

Flickering when drawing layers individually

Calling mapLoader.Draw(window, layerIndex) on map layers individually can cause layers to flicker / phase in and out, depending on the view position. This doesn't happen when window.draw(mapLoader) is called.

Collision issues

Not exactly 100% on the collision, so far I have this but it isn't recognizing my player inside of the collision for some reason. Here is my code:

Map is rendering one level high?

I seem to be having an issue with my rendering my map...

And yet within Tiled:

(It's hard to tell, but that vertical scroll bar is 'greyed out', as in you can't scroll up or down.) I can provide any code I'm using, my .tmx file, etc, just let me know what you need :)

Polyline points not returned when custom properties added to Object

For some reason if I add a custom property to a polyline object then object.PolyPoints().size() returns 0. However if I remove the custom property then the polypoints are accessible again.

MapObject::CollisionNormal: Invalid initialization of non-const ref

On GCC 4.8. Explicitly creating the vector first fixes the issue.

So the line (220):

return Helpers::Vectors::Normalize(sf::Vector2f(end - start));

becomes

sf::Vector2f tx(start-end);
return Helpers::Vectors::Normalize(tx);

The problem is in binding a non-const ref to a temporary, which is illegal according to the standard.

Tiles which move need to recalculate AABBs of Layersets

and also need to track if they enter a new patch / leave their current one

Optimise object layers which use tiles

Map objects can be drawn using tiles from tile sets. Currently these are drawn using an sf::Sprite to allow for easy transformation from information stored in the tmx file. This could be optimised with a vertex array to improve performance of layers with a lot of Tile type objects

[Question] Insert players in map and change its texture

Hi,

I am a student and this year we have to create a small video game in C ++. We decided to use some libraries to facilitate our work because we are beginner in C ++.

So, your librairy is very interesting but we didn't find the documentation and we have some basic questions (sorry if they are stupid :) ).

1. How to insert the player in map between two layers to have a z-depth effect ? I tried to use a ImageLayer and modify its tile but it didn't work.
2. When the player is inserted in the map, how to change its texture ?

Thank you and sorry for my bad english.

Graphical issues when loading new map with different tile size

I've defined two maps, an exterior using 64x64 tiles, and an interior using 32x32 tiles.
Exterior:

Interior:

My program begins in the interior, and if it detects a collision with a warp point, loads in the other map. Initially everything looks fine, but when the other map is loaded, it seems as though the tile sizes aren't updated in the loader object.

Transitioning from inside to out yields:

Transitioning from outside to in yields:
