Unity学习记录-摄像机的移动

摄像机的移动跟物体的移动是一样的：

• 使用Input.GetAxis获取坐标轴方向
• 使用transform.Translate平移
• 通过改变Translate参数控制平移速度和方向

代码示例：

public float fCameraSpe = 10;public float fMouseSpe = 200;void Update () {        //获取坐标        float h = Input.GetAxis("Horizontal");        float v = Input.GetAxis("Vertical");        float mouse = Input.GetAxis("Mouse ScrollWheel");        transform.Translate(new Vector3(h* fCameraSpe, 0 ,v* fCameraSpe) * Time.deltaTime,Space.World);        transform.Translate(new Vector3(0, 0, mouse * fMouseSpe) * Time.deltaTime);    }

4-13更新.使用鼠标中间拖动移动摄像机

   if(Input.GetMouseButton(2))        {            float fX = Input.GetAxis("Mouse X");            float fY = Input.GetAxis("Mouse Y");            transform.Translate(new Vector3(fX, 0, fY) * Time.deltaTime * fMouseSpe, Space.World);        }

摄像机平滑移动

    const float MAX_CAMERA_SPEED = 25;    const float MIN_CAMERA_SPEED = 3;    const float MAX_DecayFrame = 480;    public float fMouse2Spe = 0;    public float fMouse2Decay = 0;    private float fMouse2DecayStart = 0;    float fX = 0;    float fY = 0;  void Update () {             //按下中键移动摄像机             if(Input.GetMouseButton(0))        {            fX = Input.GetAxis("Mouse X");            fY = Input.GetAxis("Mouse Y");            fMouse2Spe = (fX*fX/ + fY*fY)/2 + MIN_CAMERA_SPEED ;            if (fMouse2Spe > MAX_CAMERA_SPEED) fMouse2Spe = MAX_CAMERA_SPEED;            fMouse2Decay = MAX_DecayFrame * (fMouse2Spe / MAX_CAMERA_SPEED);            fMouse2DecayStart = fMouse2Decay;            transform.Translate(new Vector3(-fX, 0, -fY) * Time.deltaTime * MIN_CAMERA_SPEED, Space.World);        }        else        {            if (fMouse2Decay > 0)            {                fMouse2Spe *= (fMouse2Decay / fMouse2DecayStart);                fMouse2Decay--;            }            else { fMouse2Spe = 0; fMouse2Decay = 0; }            transform.Translate(new Vector3(-fX, 0, -fY) * Time.deltaTime * fMouse2Spe, Space.World);        }    }
