A simple Unity script, that computes a grid for tile-based 2D games.
Align all your tiles in a grid and assign them as childs to an empty game object, which is representing the tile-map.
Mark every wall or obstacle with the tag "Wall".
Add GridGenerator.cs to your tile-map object.
Start the game. You should see a message like this in the console:
Grid:
1 1 1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1 1 1
1 0 0 0 0 0 0 0 0 0 0 1
1 0 0 0 0 0 0 1 0 0 0 1
1 0 0 1 0 0 1 1 1 1 1 1
1 0 1 1 1 0 1 1 1 1 1 1
1 0 1 1 1 0 1 0 0 0 0 1
1 0 0 1 0 0 1 0 0 1 0 1
1 0 0 1 0 0 0 0 0 1 0 1
1 0 0 1 0 0 0 0 0 0 0 1
1 1 1 1 1 1 1 1 1 1 1 1
GridGenerator.cs has a getter for the Grid:
public GridTile[,] Grid {
get {
return grid;
}
}That's it! Have fun! :-)
