将网格表示为对象

Question

What's reasonable way to represent a grid in terms of an object? It's part of a two dimensional graphic programming exercise where at the center of the grid is "me".

The object needs to be scalable up to 20,20.

So if I have a 3,3 grid I need to know that I am in grid 1,1 (center) and that 0,0 is lower right. And if I have an grid of 5,5 I need to know that 2,2 is the center and 0,0 is the center.

Answer 1

如果您需要降低复杂性并降低网格的其他顺序，则可以使用空间填充曲线，例如z曲线，hilbert曲线，peano曲线。
