 1 | Unity Grid Generator
 2 | ====================
 3 | 
 4 | A simple Unity script, that computes a grid for tile-based 2D games.
 5 | 
 6 | ## Usage
 7 | 
 8 | Align all your tiles in a grid and assign them as childs to an empty game object, which is representing the tile-map.
 9 | 
10 | ![Example](example.jpg?raw=true "Example")
11 | 
12 | Mark every wall or obstacle with the tag "Wall".
13 | 
14 | Add GridGenerator.cs to your tile-map object.
15 | 
16 | Start the game. You should see a message like this in the console:
17 | 
18 | ```
19 | Grid:
20 | 1 1 1 1 1 1 1 1 1 1 1 1
21 | 1 1 1 1 1 1 1 1 1 1 1 1
22 | 1 0 0 0 0 0 0 0 0 0 0 1
23 | 1 0 0 0 0 0 0 1 0 0 0 1
24 | 1 0 0 1 0 0 1 1 1 1 1 1
25 | 1 0 1 1 1 0 1 1 1 1 1 1
26 | 1 0 1 1 1 0 1 0 0 0 0 1
27 | 1 0 0 1 0 0 1 0 0 1 0 1
28 | 1 0 0 1 0 0 0 0 0 1 0 1
29 | 1 0 0 1 0 0 0 0 0 0 0 1
30 | 1 1 1 1 1 1 1 1 1 1 1 1
31 | ```
32 | 
33 | GridGenerator.cs has a getter for the Grid:
34 | 
35 | ```csharp
36 | public GridTile[,] Grid {
37 |     get {
38 |         return grid;
39 |     }
40 | }
41 | ```
42 | 
43 | That's it! Have fun! :-)
