You could also write code that takes a 2D coordinate and converts it into an index position in the grid and vice versa, both of which could be helpful later. Then you can check against this two-dimensional array to detect whether a room is located at a coordinate. Then when you spawn a new room, you create a new ID and populate the two-dimensional array at the coordinates with the position of the room in the grid. This means you'll need some way of placing, storing, and managing rooms of all different sizes.įor this, I would recommend making a two-dimensional array populated the IDs of the rooms (or lack thereof) in the game, creating a grid of sorts. With this in mind, the issue primarily becomes storing rooms and knowing whether a tile is occupied by a room or not.įrom what I can tell from looking at screenshots of the game, it appears rooms can be 1-4 grid units in width, with a constant size of 1 grid unit in height. From what I can gather, the all of the connections happen on the horizontal axis, so that is the more important of the two axes. I do not know on the height, but I would haphazard a guess that it has a finite limit, probably something large like 64. Quick disclaimer: I have not made a game like 'Fallout Shelter' and I primarily do 3D game development, so please take what I wrote below with a grain of salt! Especially since this is part of a degree, it is important that you do make development decisions and choose what works best for you and your experience.įrom what I can gather, it appears that the rooms in 'Fallout Shelter' are arranged in a grid with a width of 8 (plus at least a single elevator).

If you can, I would suggest trying whatever way seems the best/most-intuitive way and see what happens. Well, experimenting is the best way to know for sure, but I'm guessing there is a time limiting factor if the project is for a degree.
