墙工具

一张地图如果没有一个平台给玩家互动，他就不是一张地图。

当你选了这个按钮后，你可以在蓝图上直接拖曳就可以做出一面墙。你也可以搭配WASD去做一个比蓝图还要大的墙壁。但是如果你只是单点在蓝图上，墙壁只会出现一个小点，只能拖曳放大无法移动。

根据PB2的换算法典，1个正方形=10x10的像素点，而1个像素点=10bit。概念就有点像kg转换g转换mg，只是换算从1000变成了10。

绝大部分情况下unit只能是10的倍数，也就是说个位数一定是0。但是通过我们的一些科学手段我们可以让个位数强制不是0的情况。

当你加你的第一面墙，你的右边（F项）就会出现这个表格

举个例子，X有1300bit，1300bit=130像素，也等于13个正方形

X/Y: 墙壁在蓝图上的位置（用左上角作为中心点），只能单点的元件就刚好取它的中心点作为坐标。 Width/Height: 除了只能单点的元件之外，任何元件都可以调整它的长和宽，请养成墙壁与墙壁，墙壁与背景和墙壁与水面相互重叠的好习惯。
