我的生命游戏代码存在问题。它似乎只显示死亡/活着细胞的第一种模式，但不会继续将其他细胞变成死亡或活着的细胞，而是将它们全部变为死亡，然后一只活在左上角，然后全部死亡。我怎样才能使细胞正常死亡或活着？

答案 0 :(得分：0)
这就是我通常用JavaScript实现游戏的方式：
var canvas = document.getElementById("universe");
var context = canvas.getContext("2d");
var width = canvas.width;
var height = canvas.height;
var size = 2;
var cell = size - 1;
var rows = Math.floor(height / size);
var cols = Math.floor(width / size);
var bottom = rows - 1;
var right = cols - 1;
var universe = new Array(cols);
for (var x = 0; x < cols; x++) {
var col = new Array(rows);
for (var y = 0; y < rows; y++)
col[y] = false;
universe[x] = col;
}
var cx = Math.floor(cols / 2);
var cy = Math.floor(rows / 2);
var ct = cy - 1;
universe[cx][cy] = true;
universe[cx][ct] = true;
universe[cx][cy + 1] = true;
universe[cx - 1][cy] = true;
universe[cx + 1][ct] = true;
animate();
function drawCell(x, y) {
context.fillRect(size * x + 1, size * y + 1, cell, cell);
}
function drawUniverse() {
context.clearRect(0, 0, width, height);
for (var x = 0; x < cols; x++)
for (var y = 0; y < rows; y++)
if (universe[x][y]) drawCell(x, y);
}
function animate() {
setTimeout(animate, 125);
drawUniverse();
updateUniverse();
}
function updateUniverse() {
var newUniverse = new Array(cols);
for (var x = 0; x < cols; x++) {
var col = new Array(rows);
for (var y = 0; y < rows; y++) {
var l = x > 0 ? x - 1 : right;
var r = x < right ? x + 1 : 0;
var t = y > 0 ? y - 1 : bottom;
var b = y < bottom ? y + 1 : 0;
var neighbors = [ universe[l][t], universe[x][t], universe[r][t]
, universe[l][y], universe[r][y]
, universe[l][b], universe[x][b], universe[r][b] ];
var count = 0;
for (var i = 0; i < 8; i++)
if (neighbors[i]) count++;
var self = universe[x][y];
col[y] = count === 3 || self && count === 2;
}
newUniverse[x] = col;
}
universe = newUniverse;
}canvas {
border: 1px solid #000000;
}<canvas id="universe" width="559" height="179"></canvas>
希望这有帮助。
