get cell in tiled map

Newbie & Debugging Questions
#1

Hello, i wish to know how can i get cell in tiled map, … i know what you are thinking? LibGDX? no actually i wish to do it without libGDX, i wish to do it with libtiled - https://github.com/bjorn/tiled/tree/master/util/java/libtiled-java

here is an example how to use libtiled - https://github.com/bjorn/tiled/blob/master/util/java/tmxviewer-java/src/TMXViewer.java

But i played with it and couldn’t find how to get cell…

I wish to use libtiled and not libgdx, because i want to do collision detection with multiplayer server, and i dont want to install libgdx in the server, just as simple as possible.

Thanks in advance, if i will find a solution, be sure i will update you all (and maybe i will make a guide because there is 0 documentation for tiled maps)

Hey, well i couldnt find a solution but here is some information

Here how you can get a tileset tile (doesn’t related to the actual map) -

TMXMapReader reader = new TMXMapReader();
Map map = reader.readMap("assets/map.tmx");
map.getTileSets().get(index).getTile(index);    // That's how you get a tile / cell

If you want to get tile properties -

map.getTileSets().get(index).getTile(index).getProperties();

You can get any information about the tile, lets say we want to check if the tile contains key grass

map.getTileSets().get(0).getTile(1).getProperties().containsKey("grass");

Correct me if i am wrong :wink:
But i still can’t find a way to get a cell inside the map.

ANY HELP?

#3

Still can’t solve it… please help? :frowning:
maybe it has something with the map xml file?

#4

Ohh come on… how did u make multiplayer with tiled maps? how the server handled collision detection?

#5

No idea with the library you are using but with libgdx is something like this:


((TiledMapTileLayer)map.getLayers().get(0)).getCell(x,y);
#6

The thing is i want to do collision detection in the server, and installing libgdx in the server its not a good idea… so how can i make collision detection of tiled map in the server?

#7

Didn’t you answer your question yourself right there?
To be honest it is really difficult to understand what you are asking…

#8

It’s hard to understand probably because you dont really know what tileset is… tilesets are the tiles that are going to be used in the map, like this -http://nethackwiki.com/mediawiki/images/7/7c/Vanilla_tiles.png
I showed you an example how you can take tile in a tileset… not in a map, in a tileset.

Now what i am asking is how can i get a tile / cell inside my map.
for example, if i want to get the tile / cell in my map at the position (x=5,y=6), how can i do that? without libgdx?

Hope you understand, Thanks

I’m not quite familiar with libtiled since I use Libgdx but this getTileAt(int tx, int ty) seems to do the trick

#10

Wow…Looks great, thanks!
but how should i use it? getTileAt() returns null everytime i use it. any ideas?
