Hi,

First off, I wanted to thank you, I was looking for such template for about a year, was doing it in python but it was too slow. I actually modified your program to do something different bu I needed to render squares from a matrix in a heatmap like graph.

Anyway, my question is how would you go and define a colour depending on the state of the cell. I see that the colour is defined in fragmentShaderSourcewhich is used ininitOpenGL. So I don t really see how one could change this when draw` is called.

Thanks in advance.

ps: I know this repo is old, but I saw your activity a few days ago on another of your repo. Even if you don't exactly remember how this game of life is implemented, I'm just looking for a direction, not an already made solution, although that would be good too

There is a problem with the rules of life implemented here.

I experimented with setting up initial patterns, and they are not evolving as expected.

For example, creating three cells

 cell[5][5].alive, cell[5][5].nextState = true, true
 cell[5][6].alive, cell[5][6].nextState = true, true
 cell[5][7].alive, cell[5][7].nextState = true,true

(and all other cells turned off) should create a "blinker" that has a period 2 oscillation

                    *               
    ***   ->        *       ->    * * *
                    *

I also could not create a "glider".

I suspect there is a mistake with the lines

c.alive = c.nextState
c.nextState = c.alive

It is changing the alive/dead state of the cells at the same time as it is reading them to decide which cells live and which die.
