RectTransform.GetLocalCorners

参数

描述

获取计算的矩形在其 Transform 的本地空间中的各个角。

Each corner provides it's local space value. The returned array of 4 vertices is clockwise. It starts bottom left and rotates to top left, then top right, and finally bottom left. Note that bottom left, for example, is an (x, y, z) vector with x being left and y being bottom.

注意：如果 RectTransform 在 Z 中旋转，则 GetWorldCorners 的尺寸 不会更改。
