如何使相机跟随带有标签的对象

Question

我制作了一个带有标签的玩家预制件，该标签在游戏开始时在场景中生成。如何让摄像机使用播放器标签跟随玩家。

当前使用以下脚本

    public Transform target;            // The position that that camera will be following.
    public float smoothing = 5f;        // The speed with which the camera will be following.
    Vector3 offset;                     // The initial offset from the target.

    void Start ()
    {
        // Calculate the initial offset.
        offset = transform.position - target.position;
    }

    void FixedUpdate ()
    {
        // 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);
    }

Answer 1

使用这个

如

public Transform target;            // The position that that camera will be following.
public float smoothing = 5f;        // The speed with which the camera will be following.

Vector3 offset;                     // The initial offset from the target.

void Start()
{
    try
    {
        target = GameObject.FindGameObjectWithTag("Player").transform; // this is goint to find a certain tagged object from hirarchey and assing it to target.
    }
    catch (NullReferenceException ex)
    {
        Debug.Log("target gameObjects is not present in hierarchy ");
    }
    // Calculate the initial offset.
    offset = transform.position - target.position;
}

void FixedUpdate()
{
    // 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);
}

或者您可以创建一个事件，并在游戏在特定时间生成时找到带有标签的游戏Obejct

如

public Transform target;            // The position that that camera will be following.
public float smoothing = 5f;        // The speed with which the camera will be following.

Vector3 offset;                     // The initial offset from the target.

void Start()
{
    // Calculate the initial offset.
    offset = transform.position - target.position;
}
// Call this method where you spawing your target and set the tag and call this mehtod supply tag parameter 
public void FindTaggedGameObject(string tag)
{
    try
    {
        target = GameObject.FindGameObjectWithTag("Player").transform; // this is goint to find a certain tagged object from hirarchey and assing it to target.
    }
    catch (NullReferenceException ex)
    {
        Debug.Log("target gameObjects is not present in hierarchy ");
    }
}

void FixedUpdate()
{
    // 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);
}
