unity中摄像机跟随

                    Vector3 desiredPosition = circle.position;
                    Vector3 smoothedPosition = Vector3.Lerp(mCamera.transform.position, desiredPosition, smoothSpeed);
                    mCamera.transform.position = smoothedPosition;

摄像机跟随UI移动

public class CameraFollowUI : MonoBehaviour
{
    public Transform targetUI; // UI的Transform组件
    public Vector3 offset = new Vector3(0f, 0f, -10f); // 摄像机相对于UI的偏移
    public float smoothTime = 0.3f; // 平滑时间

    private Vector3 velocity = Vector3.zero; // 用于SmoothDamp的速度变量

    void Update()
    {
        if (targetUI != null)
        {
            // 获取UI的位置并加上偏移
            Vector3 targetPosition = targetUI.position + offset;

            // 使用SmoothDamp函数平滑移动摄像机的位置
            transform.position = Vector3.SmoothDamp(transform.position, targetPosition, ref velocity, smoothTime);
        }
    }
