Cellmaker
Library for simulation of cellular automata, like Conways Game of Life
How to use
Compile:
```
make
./main
or
gcc -o automaton main.c CellularAutomata/CellularAutomaton.h CellularAutomata/CellularAutomaton.c
./automaton
```
Visit main.c for complete file example.
Include:
```c
#include "CellularAutomata/CellularAutomaton.h"
```
Define your rules:
```c
//At what neighbor count will a cell survive the current iteration?
unsigned int survive[] = { 2, 3 };
size_t sSize = sizeof(survive) / sizeof(unsigned int);
//At what neighbor count will a cell get revived in the current iteration?
unsigned int revive[] = { 3 };
size_t rSize = sizeof(revive) / sizeof(unsigned int);
```
Create from array:
```c
bool arr[] =
{
0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 1, 0, 0, 1, 0, 0, 0,
0, 0, 1, 0, 1, 1, 0, 1, 0, 0,
0, 0, 0, 1, 0, 0, 1, 0, 0, 0,
0, 0, 0, 1, 0, 0, 1, 0, 0, 0,
0, 0, 1, 0, 1, 1, 0, 1, 0, 0,
0, 0, 0, 1, 0, 0, 1, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0
};
CellularAutomaton autom = newAutomatonFromArray(arr, survive, sSize, revive, rSize, 10, 10);
```
Keep in mind that this wraps around the edges, meaning that e.g. cells at the right edge neighbor the cells on the left edge.
Initialize randomly:
```c
srand(time(NULL));
//0.4 means the area will be alive by 40%
CellularAutomaton autom = newAutomaton(survive, sSize, revive, rSize, 0.4, 20, 20);
```
Run steps:
```c
for (int i = 0; i < 40; i++)
{
print(autom);
tick(autom);
printf("\n");
}
```
Print will print the automaton onto the console. However you can render it however you like by accessing the automatons buffer directly. It's a linear array of bools. Retrieve it by using:;
```c
bool* usedBuffer = currentBuffer(autom);
```
Free memory:
```c
freeAutomaton(autom);
```
