Unity 摄像机视角跟随角色移动

新建一个Capsule作为Player,创建一个cube体现人物的正反面。

 

分别创建四个空物体（注意坐标清零）

 

将相机放到Zoom节点下

public class NewBehaviourScript : MonoBehaviour

    //控制左右旋转
    public Transform Y_Axis;
    //控制上下旋转
    public Transform X_Axis;
    //控制左右倾斜

            //围绕Y轴旋转,Vector3.up是本地坐标位置
            Y_Axis.Rotate(Vector3.up * roSpeed * hor * Time.deltaTime);
        }

            X_Axis.rotation = Quaternion.Lerp(X_Axis.rotation,q,Time.deltaTime*roSpeed);
        }

        //缩放远近
