From: Leighton Wallace Date: Mon, 25 Nov 2013 01:35:09 +0000 (-0800) Subject: Automata and life is good X-Git-Url: https://git.piment-noir.org/?a=commitdiff_plain;h=2815b69095f53b912200c75cc7a91caf34bd837c;p=SugarCubes.git Automata and life is good Removed Fertility param from life, 2 is the right number. Added Automata visualization across the array of points. --- diff --git a/L8onWallace.pde b/L8onWallace.pde index d3c083f..1c9d849 100644 --- a/L8onWallace.pde +++ b/L8onWallace.pde @@ -1,36 +1,34 @@ -class CubeState { - // Index of cube in glucose.model.cubes - public Integer index; - // Boolean which describes if cube is alive. - public boolean alive; - // List of this cubes neighbors - public List neighbors; - - public CubeState(Integer index, boolean alive, List neighbors) { - this.index = index; - this.alive = alive; - this.neighbors = neighbors; - } -} - class L8onLife extends SCPattern { // Controls the rate of life algorithm ticks, in milliseconds - private BasicParameter rateParameter = new BasicParameter("RATE", 122.5, 0.0, 2000.0); + private BasicParameter rateParameter = new BasicParameter("RATE", 122.5, 0.0, 1000.0); // Controls if the cubes should be randomized even if something changes.
