Vector3 三维向量
struct in UnityEngine 结构体
Description 描述
Representation of 3D vectors and points.
表示3D的向量和点。
This structure is used throughout Unity to pass 3D positions and directions around. It also contains functions for doing common vector operations.
这个结构用于在Unity传递3D位置和方向。它也包含做些普通向量运算的函数。
Besides the functions listed below, other classes can be used to manipulate vectors and points as well. For example the Quaternion and the Matrix4x4 classes are useful for rotating or transforming vectors and points.
除了下面列出的函数,其他类用于处理向量和点。例如Quaternion和Matrix4x4类用于旋转或变换向量和点。
