Help with getting surrounding values in a 2D array

[ianadanfan (Salad)]

I’m currently working on a inventory system similar to what you would find in Apocalypse Rising 2 and I’m using a 2D array to keep track of which cells are occupied and which aren’t occupied. I can’t seem to find the values that surround another one (example below). I should also be able to define how many values I’m able to get. For example, if I have an item that takes up a 2x2 space in my inventory, I would only want to find values in a 2x2 area in the array. Does anyone know how I would go about doing this?

Since it’s 2d you can get it’s neighbors like so below

Get surrounding chunk data based on existing position

This is known as neighbors, just add and minus the xy coordinates to get the next chunk like @DenisxdX3 said. Here was my implementation, your definitions of up,right,left,down might vary depending on how you view the Axis: function Grid:GetNeighboringCells(x, y) local neighborCoordinates = { ["Up"] = {x, y-1}; ["Right"] = {x+1, y}; ["Down"] = {x, y+1}; ["Left"] = {x-1, y}; } --top/bottom = y coordinates, right/left = x coordinates local diagonalCoordinates = { ["Up Right"] = …

That’s a very simple yet effective solution to my problem! Thank you for this, I will be adapting this so it suits my needs.
