一维数组作为多维数组的等价物？ [英] Single-dimensional arrays as equivalents of multi-dimensional arrays?

问题描述

我有一个数组定义如下：

I have an array defined as follows:

Tile[,] Tiles

它包含在X轴100个元素，且在Y轴150的元件。这不同于地图在我的游戏地图，虽然，但我总是知道瓷砖在X和金额Y轴。

It contains 100 elements in the X axis, and 150 elements in the Y axis. This differs from map to map in my game though, but I always know the amount of tiles in the X and the Y axis.

，我怎么可以在上述数组转换成一维数组，遍历它们？我知道，一维数组比多维数组快2倍，这意味着很多我的比赛表现。此外，单维数组可以并行计算中使用。

Given this, how can I convert the above array to a single-dimensional array, and iterate through them? I know that single-dimensional arrays are 2 times faster than multi-dimensional arrays, and that means a lot to the performance of my game. Furthermore, single dimensional arrays can be used with parallel computing.

推荐答案

好吧，如果项目在Y轴数是固定的，每X，你可以试试这个。结果
假设A =的指望X轴的和b =的 Y轴计数的;结果
你可以定义瓷砖=新瓦[A * B]; 结果
然后瓷砖[X，Y] 变成瓷砖[X * B + Y]

Well, if items count on Y axis is fixed for every X, you can try this.
Assume a = count on X axis and b = count on Y axis;
you can define Tiles = new Tile[a*b];
Then Tiles[x,y] becomes Tiles[x*b+y]
