Question

I have the following classes:

public class Layer
{
    public Tile[,] Grid; //50x50 positions filled with my own Tile struct
}

public class Level
{
    public Layer[] Layers; //An array of layers in the level
    public List<object> Objects; //And a couple of lists of say, characters or such in the level.
}

public class Area
{
    private Level[,] _activeLevels; //3x3 array of the current level and surrounding ones.
}

What I want is to be able to call for instance..

Area.Layers[0].Grid[112, 64];

To get the Tile in Grid[12, 14] from Level[2,1].

More explanation:

Assuming a layer has 50 x 50 positions, I hope the following will explain what I want.

“if I call” => “then I actually want”

Area.Layers[0].Grid[0,0] => Area.Level[0,0].Layers[0].Grid[0,0]
Area.Layers[0].Grid[0,10] => Area.Level[0,0].Layers[0].Grid[0,10]
Area.Layers[0].Grid[0,49] => Area.Level[0,0].Layers[0].Grid[0,49]

Area.Layers[0].Grid[0,50] => Area.Level[0,1].Layers[0].Grid[0,0]
Area.Layers[0].Grid[0,60] => Area.Level[0,1].Layers[0].Grid[0,10]

Area.Layers[0].Grid[0,112] => Area.Level[0,2].Layers[0].Grid[0,12]

Also, I want to be able to call for instance..

foreach (object o in Area.Objects)
      //dostuff

To call a foreach on -all- the objects from the nine levels.

Could anyone give me a nudge in the right direction, some advice on how to achieve this, or heck, plainly code it out?

Answer 1

For Area.Layers[0].Grid[112, 64] you’d probably be better off with a method of the form Area.GetTile(0, 112, 64) implemented as

public Tile GetTile(int layer, int overallX, int overallY)
{
    return _activeLevels[overallX / 50, overallY / 50]
            .Layers[layer]
            .Grid[overallX % 50, overallY % 50];
}
