Tiled2unity For Mac
I shifted to unity few weeks ago. I am developing a 2D platformer.
For creating the maps I am using Tiled map editor from www.mapeditor.org. I have created a basic map. Included the tileSheet png and the.tmx file (saved as XML) in the Assets of the project. I am able to read the XML, that is all the gid's. But I don't know how to access a particular portion(tile) from the tileSheet corresponding to a gid. I think for this I need to load sprite in the memory and select a tile (by specifying Height and width and coords) from texture memory to display it on screen.

As given here: but its for flash, how I can achieve same thing in Unity using C#. Notice the copyPixel stuff in the flash code. I thought I could use ReadPixels but it is used for reading from screen only not the texture memory. If you can describe more carefully your problem and what you are trying to do, maybe myself or someone can help you better, for example what exactly do you mean by 'load a sprite into memory'?
Or 'select a tile'? Copying pixel data is SLOWWW, and hopefully you don't mean to be doing this in real time.

Here is my real advice though: Have you checked out UTiled? It does tiled maps in 2D in Unity so I think it already does what you want and it's free. There is also UniTMX. There is also 'Tiled Tilemaps'. Which is like $2.
I also built a system that can also do what I think you are trying to do (your link is broken, so I can't be sure). The system I built is called ' (you can search it in youtube to see if it does what you want). It allows you to attach gameObjects to tiles and have tile variants, and can do 3D tiles. Anyway, trying to roll your own pipeline from Tiled into Unity is a ton of work, and with these tools available, I think it is almost certainly unnecessary. That's just imo.


Windows Vista or higher required. Note: If after installing Spriter you get an error that vcomp120.dll is missing, please install the Visual Studio 2013 C runtime.

If you are on 32 bit Windows you only need the 32 bit version (x86). If you are on 64 bit Windows, you will need to install both the 32 bit and 64 bit versions.

IMPORTANT: If you try to install Visual Studio 2013 and the installer says you already have a newer version, then you need to uninstall the newer version so that 2013 can successfully install. Windows update will later install the latest version, but you'll keep the DLL Files Spriter needed.
