unity相机插件Cinemachine的使用笔记

首先导入插件，本插件主要用于做相机控制，先

记录三个小功能的使用方法。

第一，多个视角的切换。如果在场景中需要进行视角切换，首先点击菜单栏Cinemachine->Create Virtual Camera,就可以得到一个虚拟相机。

这些虚拟相机都是被主摄像机控制的，并不是真实存在的。

调整相机的角度，可以点击虚拟相机上的solo按钮来查看当前相机的视角

                intensity = Mathf.PingPong(i,0.5f),
                smoothness = 0.28f,
                roundness = 1,
                rounded = false,
            };
        }
        else
        {
            localProfile.profile.vignette.settings = new VignetteModel.Settings()
            {
                mode = VignetteModel.Mode.Classic,
                color = Color.white,
                center = new Vector2(0.5f, 0.5f),
                intensity = Mathf.PingPong(i, 0.5f),
                smoothness = 0.28f,
                roundness = 1,
                rounded = false,
            };
        }
	}

    public int index = 0;
    public void SwitchCamera()
    {
        index++;
        index = index % 5;
        Debug.Log("难道没有执行" + index);
        for (int i = 0; i < childCameraLst.Count; i++)
        {
            if (index==i)
            {
                Debug.Log("开启了Camera的相机"+index);
                childCameraLst[index].MoveToTopOfPrioritySubqueue();
            }
        } 
    }

第二个作用是做人物跟随，在虚拟相机的面板设置任务跟随的对象以及注视的对象部位，就可以实现跟随了，同时可以设置跟随抖动等特效。

第三，结合timeline实现相机融合。

将拍摄对象动画放在上面，然后分别设置三个虚拟相机对着对象不同的身体部位，本例子实现了镜头从腿到头到背后的镜头过度融合。

。。。。。。未完待续
