automata

This a small template to start a cellular automata using Raylib with Go. It includes functions such as GetNeighbor and GetCell, a Vec2 struct for positions, and a Game struct where you can access the grid of cells easily

controls

Space - Pause simulation Mouse wheel - Simulation Speed Ctrl + Mouse wheel - Zoom

grid

The grid is a 2D array of pointers to the Cell struct.
The cell struct has 2 values: Color: the color of the cell, Alive: wether the cell is or not alive, and Position a Vec2 that stores the cell position.

game

The Game struct has:

• Width: The window width
• Height: The window height
• CellSize: The size of each cell: if Width and Height is 800 and CellSize is 10, there will be 80 cells.
• InitCellSize: The initial size, to know the size for NextGrid
• Grid: The grid of cells.
• NextGrid: Temporary grid to store the next state before it appears. It also has the GetNeighbor, GetNumberAliveNeighbors, GetCell functions to easily make your rules for the automata.

consts

The main.go file has these consts:

const Width = 800
const Height = 800
const CellSize = 10

// Iterations Per Second (variable to be controlled by user)
var Speed_IPSecond = 10

These are used to set the other values easily.

how to use:

Click "Use this template" Clone the new repository. Edit the init cells in main.go. By default even cells are alive. Edit update.go this is the stuff that will happen to the cells each iteration
