Simpl,

I had CMake errors with an SFML project last week and I needed to have SFML_ROOT defined in the path variables. And SFML_ROOT would link to where my SFML libraries are located on my computer ( specifically the Cmake folder in SFML ). I'm not sure if that'll help you. It looks like you need a destination to install though, did you specify a destination in the "where to build the binaries" if you're using CMake GUI?
The truth will set you free but first it will piss you off.

I'm assuming you're trying to build on windows. There's a line which installs the pugixml lib on linux which should have an 'if(UNIX)' condition which I haven't added yet. Commenting this out should fix it for now.

I'm currently having issues with the TMX loader and setting object's visablity to false to have them not drawn.

if (handleEvent.type == sf::Event::EventType::KeyPressed && sf::Keyboard::isKeyPressed(sf::Keyboard::E))
                for(auto layer = ml.GetLayers().begin(); layer != ml.GetLayers().end(); ++layer)
                {
                        if(layer->name == "Interactables")
                        {
                                for(auto object = layer->objects.begin(); object != layer->objects.end(); ++object)
                                {
                                        if (object->Contains(sf::Vector2f(tankSprite.getPosition().x, tankSprite.getPosition().y)))
                                        {
                                                if (object->GetType() == "Computer")
                                                {
                                                        for(auto object2 = layer->objects.begin(); object2 != layer->objects.end(); ++object2)
                                                        {
                                                                if (object2->GetType() == "Laser")
                                                                        if (object2->GetName() == object->GetName())
                                                                        {
                                                                                object2->SetVisible(false);
                                                                                object2->SetProperty("State", "Off");
                                                                        }
                                                        }
                                                }
                                        }
                                }
                        }
                }
That's how I am doing it but when I look at the map the object is still being drawn. I've checked to make sure the objects I want are not being set to visable when drawn with
for(auto layer = ml.GetLayers().begin(); layer != ml.GetLayers().end(); ++layer)
        {
                if(layer->name == "Interactables")
                {
                        for(auto object = layer->objects.begin(); object != layer->objects.end(); ++object)
                        {
                                if (object->Visible())
                                        std::cout << "STILL THERE! " << object->GetType() << std::endl;
                        }
                }
        }

Sorry if this code is rather sloppy, I've been quickly writing it as a proof of concept for tmx loader. Any insight to what I am doing wrong and why the objects are still being drawn on the screen would be greatly appreciated.

Thanks,
MJBrune

You're right. I've had a look and the object visibility flag has no effect. This is because originally objects were drawn with sprites, but have since been updated so that all objects are now part of a vertex array - making it much harder to change the visibility of individual objects (if not impossible). An oversight on my part. I can only suggest that to attach your own sprites to objects if you want an immediate fix, until I decide how to proceed on this.

Just a shot in the dark but couldn't you store all the vertices in an object and when the visibility flag is set you can then calculate to draw only the visible objects? Somehow taking advantage of https://www.opengl.org/sdk/docs/man/docbook4/xhtml/glDrawRangeElements.xml this function?

That looks like a reasonable tactic. I had considered the possibility of rewriting much of the drawing code using OpenGL, although I have very little time to work on this right now (beyond opening a new issue). Pull requests are always welcome ;)

Hello !

I'm new in SFML programming, but thank you very much for your tmxloader, it's very useful !
I'm trying to add an object in the map, it's quite easy (I used your example AddRemoveObjects.cpp) but I can't figure out how to give the object a texture.
The object is well created and drawn, I can see it with DrawDebugShape() but it remains an empty box with no texture.

I tried to create a LayerSet with the good texture, AddTile and then use SedQuad on my object, but this has no effect.

Can you help me ?

Thank you !

I've not actually tried this (it's been a while since I looked at the map loader) but I think you're on the right track. The layerset you create has to be attached to a layer to be drawn iirc, and the object needs its type set to 'tile'.

Hi there !

I try to use the TMX map loader with QTCreator (under Ubuntu)

When I compile I get those errors :

Quote
15:57:23: Running steps for project TestTML...
15:57:23: Configuration unchanged, skipping qmake step.
15:57:23: Starting: "/usr/bin/make"

I also get a lot of warnings, but it looks like the errors have something to do with the zlib ?

If I do a "locate libz.so" in a terminal, I get this :

It's not so friendly to push the thread only after 5 hours, especially considering that this is not a general SFML topic that the whole community can answer, but a user's project. The developer most probably has a life apart from this project, so have some patience and research on your own while you're waiting...

Hello,

It's ok, I found where was the problem, I added "-lz" to my .pro file...

-lzlib

Thank you, it's not -lzlib but you put me on the track.

@Nexus : Sorry

Well from the looks of it you're checking to see if the player has fallen into the object, and stop the falling when it has, but you never move the player back out again. Presumably it'll never move, because left/right are always false while the object contains the player. At a most basic level I use the MapObject function GetCollisionNormal() (I think it's called) and use it to reflect the player's current velocity which will move it back out of the object again. For a much better article on 2D platformers, I like this article, however.

I feel dumb stupid, but could you explain how to build your TMXLoader? On windows. With VS2013 Express.

I don't work with C++ and I have absolutely no idea about what to do to build it. Or is there a binary somewhere that I can't see?

Thanks.
