i am trying to create game objects in the screen aligned from the center, they are just characters ordered from the center to the sides, i am pretty bad explaining things so i will just attach an image

FYI On about in Unity in 2D
The tile map (which is under the grid) has a different position then other game object I create.
No matter where I create the tile maps object, they have a position of (0,0,0).
However I want to get the position of the tile map object in relation to the centre of the world.
the following is screenshots of the objects:
The boxes on the top right is the rest of the objects and the centre of the world.
I've tried stuff I've found on the internet but really understood it and it hasn't worked so if you could explain your solutions too that would be a great help.
I am trying to create an interactive boardgame in Unity, using hand gestures to activate mechanics. The game will be projected on a table with a camera attached next to it, which will be used to capture motion.
The game consists of two grids, one 30x30 hidden tile grid, with a map grid on top of it.
My question is then: What is the smartest way to go around synchronizing the camera with the hidden tile grid, so I can see if a detected BLOB from my EmguCV is on top of set tile?
I've considered:
Creating another tilemap for the camera, and check if the tile number
in both tilemaps are equal to eachother.
Check if tile center position is close to blob center position, using
Unitys method Vector2.Distance
I am trying to make a VR game with google cardboard in unity. However we can not find a way to display score text right in front of the player. However when I add 2D text it is only on one side and therefore on one side of the eye and getting the position right for 2 texts is hard. If I use 3D text and set in front of the players position I think it will go into the wall if a player hits one. Is their any way to display a score on google cardboard / Unity VR.
You can either use native Unity Canvas UI or Googles hack to render OnGUI calls onto a texture.
I would definately recommend Canvas as that is the way Unity is working on their UI features, and it has much better layout capability.
To use canvas, Right click in the hierarchy and add UI->Text. You will automatically get a canvas. The important part is set the canvas to world-space (not screen space overlay). Then drag the canvas game object so it is a child of the Google Cardboard Main head object. Scale it down (like x:0.001,y:0.001,z=0.001) because by default it will be massive. To avoid going through walls position it about 0.5m in front of the camera - within any collider you may have.
there is another approach as well which you can place that canvas under camera make it world space, and then adjust it as you want, after that where ever you look at it will be seen easily ( as suggested by earlier user in answers) as you can see below in picture i placed canvas > Text > under camera which i used for oculus/ google camera
I am making an RPG game using an isometric tile engine that I found here:
http://xnaresources.com/default.asp?page=TUTORIALS
However after completing the tutorial I found myself wanting to do some things with the camera that I am not sure how to do.
Firstly I would like to zoom the camera in more so that it is displaying a 1 to 1 pixel ratio.
Secondly, would it be possible to make this game 2.5d in the way that when the camera moves, the sprite trees and things alike, move properly. By this I mean that the bottom of the sprite is planted while the top moves against the background, making a very 3d like experience. This effect can best be seen in games like diablo 2.
Here is the source code off their website:

Any help would be great, Thanks
Games like Diablo or Sims 1, 2, SimCity 1-3, X-Com 1,2 etc. were actually just 2D games. The 2.5D effect requires that tiles further away are exactly the same size as tiles nearby. Your rotation around these games are restricted to 90 degrees.
How they draw is basically painters algorithm. Drawing what is furthest away first and overdrawing things that are nearer. Diablo is actually pretty simple, it didn't introduce layers or height differences as far as I remember. Just a flat map. So you draw the floor tiles first (in this case back to front isn't too necessary since they are all on the same elevation.) Then drawing back to front the walls, characters effects etc.
Everything in these games were rendered to bitmaps and rendered as bitmaps. Even though their source may have been a 3D textured model.
If you want to add perspective or free rotation then you need everything to be a 3D model. Your rendering will be simpler because depth or render order isn't as critical as you would use z-buffering to solve your issues. The only main issue is to properly render transparent bits in the right order or else you may end up with some odd results. However even if your rendering is simpler, your animation or in memory storage is a bit more difficult. You need to animate 3D models instead of just having an array of bitmaps to do the animation. Selection of items on the screen requires a little more work since position and size of the elements are no longer consistent or easily predictable.
So it depends on which features you want that will dictate which sort of solution you can use. Either way has it's plusses and minuses.
I'm totally new in game-dev and would like to know the best practice about above question.
Let me explain more.
I want to create 2D game with top-down view and with free movement (without snapping to the grid) just like any Zelda game on GameBoy.
How should I store map bounds? Is there a way to do this automatically? For example I have a texture with background and texture with foreground where black color should appear transparent and should allow to move in space of it.
Thanks in advance.
For easy 2D collision detection, you'll probably implement bounding boxes.
Basically you will create a rectangle that represents every Game Object. The coordinates and size of the rectangle will be the same as the Texture2D (it is common to make this a property on the given class). Every time you update the position of your Texture, you update the position of your bounding box.
Now to check for collision, just loop through your game objects and see if any of the bounding boxes intersect.
Once you get the idea, you'll see that its very easy to implement. XNA also provides some math helpers to abstract the math (though its simple addition and subtraction).
