Each alive cell has 4 states: Up, right, down, left. Update: Click here to get Otomata for your iPhone / iPod / iPad! Official facebook page: Also this reddit page has many examples: And there is a subreddit for Otomata: Otomata is a generative sequencer. float chanceToStartAlive = 0.Click on the grid below to add cells, click on cells to change their direction, and press play to listen to your music. Each cell will have the same random chance of being made alive, and you should make sure that this chance value is set in a variable somewhere, because we'll definitely want to tweak it later and having it somewhere easy to access will help us with that. We're going to start out by randomly setting each cell to either dead or alive.
Now we need to set up our grid so we can begin building our caves. That's fine for us! If an array index (x,y) is false, we'll say that the cell is empty if it's true, that tile will be solid rock.Įach one of these array positions represents one of the 'cells' in our cellular grid.
In most programming languages, this array will initialise with all its values set to false. This makes accessing the array more natural in code. Tip: Notice that the first index is the x-coordinate for the array, and the second index is the y-coordinate. Here's us initialising our grid of cells: boolean cellmap = new boolean This suits us because we're only interested in whether a tile is solid or not. We're going to represent our cellular grid as a two-dimensional array of Boolean ( true or false) values. We're going to implement a system very similar to Life, but instead of producing funny patterns and shapes, it's going to create amazing cave systems for our games. The Game of Life is an example of a cellular automaton - a grid of cells that are governed by certain rules. Infinite loops, machines that spit out shapes, and more. Nice and simple! Yet if you try out different combinations of starting grids, you can get very strange outcomes.
If a living cell has two or three living neighbours, it stays alive.If a living cell has less than two living neighbours, it dies.Life wasn't really a game it was more like a simulation that took a grid of cells (that could be either alive or dead) and applied some simple rules to them.įour rules were applied to each cell in every step of the simulation: In the 1970s, a mathematician called John Conway published a description of The Game Of Life, sometimes just called Life. Let's get started by asking a simple question: what on earth is a cellular automaton, anyway?
#OTOMATA MUSIC GAME CODE#
It all uses the same code and output, which makes this a really flexible tool.
#OTOMATA MUSIC GAME GENERATOR#
So in fact, you could use this generator for all sorts of games besides dungeon-crawlers: random levels for strategy games, tilemaps for platform games, perhaps even as arenas for a multiplayer shooter! If you look carefully, flipping the solid and empty blocks makes an island-generator too. This generator actually returns us a big two-dimensional array of blocks, each of which is either solid or empty. We'll talk about what the different settings do in due course. Click 'New World' to produce a new cave to look at. Take a look at the demo below to see the kinds of output you'll be able to get. Caves are great for all sorts of game genres and settings, but they particularly remind me of old dungeons in role-playing games. In this tutorial, we're going to build a cave generator.
