Unity3d Unity相机平滑/减轻阻力

当我拖动相机时，我试图使相机放松或产生惯性，这样当我放下相机时，相机就会轻松就位。我想根据我投掷/拖动相机的力来移动它

这是我用来拖动相机的实际代码，但里面没有平滑的缓和

using UnityEngine;
using System.Collections;

public class swipeCamera: MonoBehaviour
{
    Vector3 hit_position = Vector3.zero;
    Vector3 current_position = Vector3.zero;
    Vector3 camera_position = Vector3.zero;
    float z = 0.0f;

    // Use this for initialization
    void Start()
    {
    }

    void Update()
    {
        if (Input.GetMouseButtonDown(0))
        {
            hit_position = Input.mousePosition;
            camera_position = transform.position;

        }
        if (Input.GetMouseButton(0))
        {
            current_position = Input.mousePosition;
            LeftMouseDrag();
        }
    }

    void LeftMouseDrag()
    {
        // From the Unity3D docs: "The z position is in world units from the camera."  In my case I'm using the y-axis as height
        // with my camera facing back down the y-axis.  You can ignore this when the camera is orthograhic.
        current_position.z = hit_position.z = camera_position.y;

        // Get direction of movement.  (Note: Don't normalize, the magnitude of change is going to be Vector3.Distance(current_position-hit_position)
        // anyways.  
        Vector3 direction = Camera.main.ScreenToWorldPoint(current_position) - Camera.main.ScreenToWorldPoint(hit_position);

        // Invert direction to that terrain appears to move with the mouse.
        direction = direction * -1;

        Vector3 position = camera_position + direction;

        transform.position = position;
    }
}

谢谢大家!

放松意味着随着时间的推移逐渐行动

因此，此类行为通常通过或其他lerp函数以及

Update

方法实现

using System.Collections;

public class swipeCamera: MonoBehaviour
{
    public float speed = 2.0f;//easing speed

    Vector3 camera_position = Vector3.zero;
    float z = 0.0f;

    bool flag = false;
    Vector3 target_position;

    void Start()

zwcloud非常感谢你的工作，真是魅力四射！非常感谢你的帮助！！先生，你找到了一个新朋友，我很高兴这对你有帮助。请记住在您能够投票时向上投票。：）嘿，伙计们，迟来的建议，但如果有人再读一遍：）我会使用

Vector3.Lerp（）

。这会使摄影机的移动更加平滑，因为它会在最后慢慢减小<代码>transform.position=Vector3.Lerp（transform.position，targetPos，Time.deltaTime*DragSpeed）zwcloud谢谢你这么多，工作得很有魅力！非常感谢你的帮助！！先生，你找到了一个新朋友，我很高兴这对你有帮助。请记住在您能够投票时向上投票。：）嘿，伙计们，迟来的建议，但如果有人再读一遍：）我会使用
