将主摄像机缓慢移动到另一个位置

Question

我想在按下按钮时将主摄像机从一个点缓慢移动到另一个点。此按钮调用具有移动相机代码的方法。

我曾尝试使用 Lerp 方法，但摄像机位置变化太快，以至于当我单击按钮时摄像机直接移动到新位置。我想让相机慢慢移动到一个新的位置。

下面是我的代码，谁能帮帮我。

using System.Collections;
using System.Collections.Generic;

using UnityEngine;

public class Cameramove : MonoBehaviour
{
    public GameObject cam;
    Vector3 moveToPosition;// This is where the camera will move after the start
    float speed = 2f; // this is the speed at which the camera moves
    public void move()
    {
        //Assigning new position to moveTOPosition
        moveToPosition = new Vector3(200f, 400f, -220f);
        float step = speed * Time.deltaTime;
        cam.transform.position = Vector3.Lerp(cam.transform.position, moveToPosition, step);
        cam.transform.position = moveToPosition;
        
    }
    
}

Answer 1

将 lerp 与框架一起使用更容易，您需要在更新函数中使用它。尝试使用Unity docs 中的示例：

public int interpolationFramesCount = 45; // Number of frames to completely interpolate between the 2 positions
int elapsedFrames = 0;

void Update()
{
    float interpolationRatio = (float)elapsedFrames / interpolationFramesCount;

    Vector3 interpolatedPosition = Vector3.Lerp(Vector3.up, Vector3.forward, interpolationRatio);

    elapsedFrames = (elapsedFrames + 1) % (interpolationFramesCount + 1);  // reset elapsedFrames to zero after it reached (interpolationFramesCount + 1)

    Debug.DrawLine(Vector3.zero, Vector3.up, Color.green);
    Debug.DrawLine(Vector3.zero, Vector3.forward, Color.blue);
    Debug.DrawLine(Vector3.zero, interpolatedPosition, Color.yellow);
}

尝试使用光滑的潮湿。

这是您应该尝试的新代码：

using System.Collections;
using System.Collections.Generic;

using UnityEngine;

public class Cameramove : MonoBehaviour
{
    Vector3 matric;
    public GameObject cam;
    Vector3 moveToPosition;
    float speed = 2f; 
    bool move_ = false;

    void Update(){
         if(move_){
              //Assigning new position to moveTOPosition
              moveToPosition = new Vector3(200f, 400f, -220f);
              cam.transform.position = 
              Vector3.SmoothDamp(cam.transform.position,
                            moveToPosition,
                            ref matric, speed);
         }
    }

    public void move()
    {
        move_ = true;
    }
}
