Vector3.Project

`Vector3.Project`方法是Unity引擎中的一个向量投影方法，用于将一个向量投影到另一个向量上。具体来说，该方法会将一个向量`vector`投影到一个法向量`normal`上，得到一个垂直于`normal`的向量，即在`normal`方向上的向量。

方法签名如下：

public static Vector3 Project(Vector3 vector, Vector3 normal);

其中，`vector`参数代表需要投影的向量，`normal`参数代表投影的法向量。该方法返回投影向量，类型为`Vector3`。

示例代码：

Vector3 v1 = new Vector3(1, 2, 3);
Vector3 v2 = new Vector3(0, 1, 0);
Vector3 projection = Vector3.Project(v1, v2);
Debug.Log(projection); // 输出结果为 (0, 2, 0)

在上述示例代码中，将向量`v1`投影到向量`v2`上，得到的投影向量为`(0, 2, 0)`，即在`v2`方向上的向量。

在实际应用中，`Vector3.Project`方法可以用于实现向量的投影运算、碰撞检测、角色朝向等功能。

`Vector3.Project` is a method in Unity's `Vector3` class that projects a vector onto another vector.

The method takes two `Vector3` parameters: `vector` and `onNormal`. `vector` is the vector you want to project, and `onNormal` is the vector you want to project onto.

The method returns a `Vector3` that represents the projection of `vector` onto `onNormal`. The projection is calculated by taking the dot product of `vector` and `onNormal`, and dividing the result by the square magnitude of `onNormal`. The resulting vector is then multiplied by `onNormal`.

Here's an example of how to use `Vector3.Project`:

Vector3 vector = new Vector3(1, 2, 3);
Vector3 onNormal = new Vector3(0, 1, 0);
Vector3 projection = Vector3.Project(vector, onNormal);

In this example, `vector` is projected onto the `y` axis by passing in `(0, 1, 0)` as the `onNormal` parameter. The resulting `projection` vector would be `(0, 2, 0)`, since the projection of `vector` onto the `y` axis would have no `x` or `z` component.

`Vector3.Project` is a method in Unity's `Vector3` class that projects a `Vector3` onto another `Vector3`.

The method takes two parameters:
- `vector`: The `Vector3` to project.
- `onNormal`: The `Vector3` onto which the `vector` will be projected.

The method returns a `Vector3` that represents the projection of `vector` onto `onNormal`. The returned vector is the component of `vector` that is parallel to `onNormal`.

Here's an example usage of `Vector3.Project` in Unity:

Vector3 vectorToProject = new Vector3(1, 2, 3);
Vector3 projectionNormal = new Vector3(0, 1, 0); // projecting onto the y-axis

Vector3 projectedVector = Vector3.Project(vectorToProject, projectionNormal);

Debug.Log(projectedVector); // Output: (0, 2, 0)

In this example, we project the `vectorToProject` onto the `projectionNormal`, which is the y-axis. The resulting `projectedVector` is (0, 2, 0), which is the component of `vectorToProject` that is parallel to the y-axis.
