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 :http://gamedevelopment.tutsplus.com/tutorials/parsing-and-rendering-tiled-tmx-format-maps-in-your-own-game-engine--gamedev-3104
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.
Thanks.
If you're working in Windows then the Tiled2Unity Utility sounds like it will fit your needs. It exports Object Layers and was made with Unity 4.3 features in mind.
(Full disclosure: I'm the author of Tiled2Unity)
EDIT: Tiled2Unity is available for Mac users as well now. There is a command-line version for Linux users. (all free)
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... free.
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 'Tiled to Unity' (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.

I am trying to create a C# software that can control the CNC machines, First I am trying to create a 3d Space area in the PictureBox (or Pannel), I have gone through the internet and reached about this and I got one video. He made a 3D place in the form space, and it was a good tutorial but I don't know how to create a coordinate system in that space as you see in the image that I have given below.
Pls, Help me to do this.
enter image description here
enter image description here
If I get the proper solution for this, in the future I can develop this project.
Thank you, guys...
Update:
Actually, I have designed a C# program That controls the CNC machines,
For example, we can take UGS, There is much software out there but I need to create this in C#. The Only thing I am suffering here is the 3D coordinate system. How to create the Axis diagram in 3D.
Example: Planet Cnc's "Cnc USB Controller" I want to create this software in C#.
Thanks...
Build a CNC CAD programmer from skratch it's not a trivial activity.
You should be skilled in:
Math and Geometry in particular (vector/matrix calculus, base transformation, ...)
A language to comunicate with CNC (maybe G Code)
3D file formats
etc.
This is old, and you should have fixed the problem by now... but I hope to help someone in the future.
Have you seen Helix-toolkit? This library provides easy 3D camera and object controls for .Net Framework. I used this library in WPF C# for an application that generated G-Code for a CNC machine... this saved me in the simulation.
You can import 3D models (.3Ds or .obj) from your machine to 3D Panels (HelixViewport3D) and use them in the simulation or create meshes on demand in C#.
The documentation is simple, but on GitHub there are lots of examples.

I want different images to be displayed from different point of view. For the whole concept explaination please look at the images. they explain my idea/query!
As in the first image you see that there are three people at different angle looking at the monitor. Now i want the webcam to track the eyes and show the particular defined image to the user> For example: If user is at 45 degree angle then show image1.png
Depending upon the user's prespective of watching. The computer should show the image.
(the lady is the game character for representation purpose)
Can you please guide me on what steps can be taken to accomplish this? Is there any plugin available for unity that tracks faces? Please guide me
Also thanks for the compliments on my sketching skills xD
Stackoverflow is not really meant to recommend plugins, since the choice is usually opinion based so there is no exact answer.
That being said, on of the most common used API for computer vision (meaning interpreting images, including face recognition) is OpenCV, so that could be a good start for you to look at that.
And fortunately for you, there is a Unity plugin for OpenCV
It is too broad to give you more details about how it works here. You should try to make it work, and if you have a problem with your code, open a new question with the code portion that you struggle with.
PS: nice sketching skills
Perhaps easier option would be to use Kinect
(trying to detect face or eyes from that far might be shaky?)
With Kinect you can get skeletons for multiple people, and getting the angle between target and those kinect avatars would be easy.
If there is no space to put kinect in good position,
could consider placing it on the ceiling above (and then use depth data only to detect people in its view)
Only issue is that apparently Microsoft has stopped Windows kinect support,
so you would need to find 2nd hand versions.. (Unity Asset store still has some kinect plugins and examples available)

Or look for kinect alternatives that work with unity, try RealSense cameras:

i recently downloaded "Tiled Map Editor" - because i heard it was a great tool for making maps. I also got a .tmx "compiler", well, something that made the .tmx usable in XNA.
I've created a map and imported it and it worked fine, but now the tricky part comes...
If i add a collision layer in "Tiled" and adds a tile that indicates block part, how would i get data and values, and how would i be able to use it in XNA? And how would i make so that the player spawns in a certain location, and also, how do i add things as events, and movable objects?
You don't have to tell me everything that, but it would be cool if you could give me an idea on how to get data and values from the .tmx and convert it into rectangles or such things^^
Thanks in advance!
I know nothing about tmx file but a little about collision.
I'm going to take a punt that your ".tmx "compiler"" is something that allows files of this type to be included in the content pipeline. Somewhere in this build process will be the vertex data that you can use to construct the collision primitives (shapes) for collision detection later.
ASIDE: it took me ages to get my head around the content pipeline - not for the faint hearted but the way to go. They are samples on the XNA website to get you going
I have little experience with using 3D models exported to .x files in DirectX.
For example for make watersurface or some objects star, car, grass or whatever.
Can I do it in OpenGl similar way like in DirectX? I mean using .x file to render the 3D model? Or other file, or is that bad way? If it is bad way, what should I do?
Situation: project of simple 3D game OpenGL + C#, I have rendered terrain from Height map and I need to improve it by objects, grass, water, teleports.. so I'm finding easy way to render 3D objects.
Can I do it in OpenGl similar way like in DirectX?
Yes, and no. Let me explain.
The DirectX .x file format came to life with DirectX 3, which was an utter mess. Loading even the most simple geometry was an awfully exhausting task. As of such, support for a loading model geometry from files was added into the Direct3D environment.
However DirectX never enforced a specific file format, and as it matured, somewhere around version 7 Direct3D became usable. As soon as getting geometry into Direct3D became something simple, the .x file format was no longer needed. And frankly, there are only very little serious programs that actully use .x for their assets.
OpenGL never had the need for a builtin format, because setting up and drawing geometry – that has already been read into memory of course – could be managed in as little as 10 lines of C code. So the only difficulty lies in parsing a file format into structures in memory. This is not a task for a API designed for drawing stuff, bur for libraries that are designed to do I/O.
To make a long story short: OpenGL has no built in support for some file format, but you can use any file format you like to, and coax it into OpenGL. The .x file format is well documented and you can find ready to use libraries to load or write your own.
The short answer is no. You cannot do that in OpenGL. First, let me clarify what is going on here.
DirectX, like OpenGL, is a high-power graphics API. While there are differences in individual features you can think of them as nearly identical.
However, DirectX differs from OpenGL in a big way. Specifically, Microsoft has lots of tooling and libraries built on top of DirectX. For example, the XNA library, Visual Studio add-ins, and so on.
When you have a ".x" file, what you are really doing is using part of the additional libraries and machinery built on top of DirectX to do the loading and displaying of the model.
While there are lots of libraries for loading models and displaying them in OpenGL, they aren't "in the box" like they are with DirectX.
For your game, if you are going with OpenGL I would recommend you stick with a different file format for your 3D assets. COLLADA would be a good starting point.
I need to take a 2D shape file in the ".shp" format that ArcGIS accepts, and add 3D information supplied by a raster DEM. I'm looking for how to do this with the ArcObjects API. I'd like to do it in C#, but examples in any .NET language would be welcome. The only thing I've been able to find are descriptions of how to do this manually in one of the ArcGIS desktop apps. Like this helpful HowTo article, or the wonderful full color illustrations on page 22 of this tutorial. That's great and all, but I need to use this feature in the middle of an automated chain of operations. I don't want to have a manual step in the middle.
OK. I figured it out. I'm jotting down an outline of what I did here in case anyone else runs into the same problem.
The key method is ISurface.InterpolateShape. It will copy an existing 2D IGeometry and add 3D information to it from a surface (raster or TIN). I translated this example VB6 code from VB6 to C#, and modified it to call InterpolateShape for each copied IGeometry in the input shape FeatureClass before inserting it into the output FeatureClass.
I won't post any of the code here because I developed it on my company's dime, but this should be enough to figure it out reasonably quickly. Hopefully this will help some other struggling developer get through the problem more quickly.
