我的人生逻辑游戏有问题吗？
我的人生逻辑游戏有问题吗？
提问于 2016-02-26 14:36:43
我在JavaScript中编写了康威的生活游戏，它似乎在屏幕上产生某种东西，但它似乎没有遵循相同的逻辑，也没有以相同的方式运行到Conways的生命游戏中。我不知道出了什么问题，为什么会这样运行，在我看来，我的代码应该遵循正确的规则。有人能找出它为什么不能正确运行吗？下面是指向JSFiddle https://jsfiddle.net/nw4Lw7z9/1/的链接
//object constructor
function cell(){
this.alive = Math.random() >0.8;
this.neighbours = 0; //number of live neighbours
this.checkneighbours = [[-1,-1],[-1,0],[0,-1],[-1,1],[1,-1],[1,0],[0,1],[1,1]];
}
function GoL(size){
this.size = size;
this.grid = this.makeGrid(size);
};
GoL.prototype.makeGrid = function(size){
var grid = [];
for(var i=0; i<size; i++){
var row=[];
for(var j =0; j<size; j++){
row.push(new cell());
}
grid.push(row);
}
return grid;
};
GoL.prototype.drawGrid = function(){
grid.innerHTML = '';
for(var i=0;i<this.size;i++){
var row =this.grid[i];
var rowCell="";
for(var j=0;j<this.size;j++){
var cell = row[j];
if(cell.alive){
rowCell += "X|";
}else{
rowCell += " |";
}
}
grid.innerHTML = grid.innerHTML + rowCell + "\n";
}
};
GoL.prototype.underpopulation = function(ro,col){
var cell = this.grid[ro][col];

GoL.prototype.cellstatus = function(ro,col){

for(var j=0; j<this.size;j++){
this.cellstatus(i,j);

您的update函数很难理解。我把它清理干净了。试试看：
GoL.prototype.update = function(ro,col){
var cell = this.grid[ro][col];
// Uncomment this. Need to re-set every iteration (and fix typo)
cell.neighbours = 0;
for(var i = 0; i < cell.checkneighbours.length; i++){
// Get new indices
var newRow = ro + cell.checkneighbours[i][0];
var newCol = col + cell.checkneighbours[i][1];
// Check that indices are in range
if (newRow >= 0 && newRow < this.grid.length && newCol >= 0 && newCol < this.grid[newRow].length) {
if(this.grid[newRow][newCol].alive){
cell.neighbours++;
}
}
}
