Re^2: My Conway's Game Of Life Attempt

The intent of the substr pair would be clearer as:

substr($new_world->[$y], $x, 1) = ( $n == 3 ? '0' : ' ' );

[eric256]

Wouldn't that kill the cell if its $n == 2 and its alive? Basicaly if its $n==2 then the cell remains alive or dead, whichever it was already, dies if its $n<2 or $n>3, and becomes alive if $n==3.

See what I mean by the original being unclear, I misunderstood what it did :)

to sum the rules up: less than 2 neighbours: dead in the next turn 2 neighbours: unchanged (dead or alive) in the next turn 3 neighbours: becomes/stayes alive in the next turn more than 3 neighbours: dead in the next turn
