最简洁的方法来初始化大型2D阵列

Question

你可能笑得很开心.我正在创建一个基于Socket.IO的RPG的大地图.这是愚蠢的吗？我知道我可以使用5行代码创建二维数组,但我需要数组中有不同的数字.例如,0 =允许走路,1 =不允许走路.想象一下,数字变化很大,0s,1s等.

如果有更好的方法请告诉我.也许是一种从文本文件或其他东西中读取的方法？

Answer 1

您可以初始化m x n空矩阵,然后只存储1s 的坐标:

var ones = [[2,3], [5, 12], ...];

for(i=0;i<ones.length;i++)
    matrix[ones[i][0]][ones[i][1]] = 1;

或者只是使用位图,如其他建议 - canvas可能会帮助您.
