Unity3d 团结：停止摄影机跟随玩家？

我正在学习《生存射手统一》教程，在该教程中，给定的代码用于使相机跟随玩家。该代码正在工作，但我如何修改它，使其在给定的X和Y点停止跟随玩家

代码

只要停止更新他的职位：

private bool followPlayer = true;
void FixedUpdate ()
{
    if(followPlayer){
        // Create a postion the camera is aiming for based on the offset from the target.
        Vector3 targetCamPos = target.position + offset;

        // Smoothly interpolate between the camera's current position and it's target position.
        transform.position = Vector3.Lerp (transform.position, targetCamPos, smoothing * Time.deltaTime);
    }
}

---

将followPlayer的值更改为false，它将停止跟踪

只需停止更新其位置：

private bool followPlayer = true;
void FixedUpdate ()
{
    if(followPlayer){
        // Create a postion the camera is aiming for based on the offset from the target.
        Vector3 targetCamPos = target.position + offset;

        // Smoothly interpolate between the camera's current position and it's target position.
        transform.position = Vector3.Lerp (transform.position, targetCamPos, smoothing * Time.deltaTime);
    }
}

将followPlayer的值更改为false，它将停止跟随

以确定玩家是否在给定点，您需要检查玩家与该点之间的距离，例如：

public Transform target;                // player position
public Transform stopingPoint;          // stopping point position
public double tolerance;                // the "radius" of stopping point

private bool followPlayer = true;

    ...

void FixedUpdate ()
{
    if(!followPlayer)
        return;
    followPlayer = Vector3.Distance(target.position, stopingPoint.position) <= tolerance;

    ...
