Unity3D实现鼠标控制视角转动

前面，学了物体的移动功能，现在来学一下c#实现鼠标控制摄像机(视角)移动。

代码如下：

c#脚本(在unity 5.5.1 下能运行)：

using system.collections;
using system.collections.generic;
using unityengine;


public class mouseview : monobehaviour {

  public enum rotationaxes
  {
    mousexandy = 0,
    mousex = 1,
    mousey = 2
  }

  public rotationaxes m_axes = rotationaxes.mousexandy;
  public float m_sensitivityx = 10f;
  public float m_sensitivityy = 10f;

  // 水平方向的 镜头转向
  public float m_minimumx = -360f;
  public float m_maximumx = 360f;
  // 垂直方向的 镜头转向 (这里给个限度 最大仰角为45°)
  public float m_minimumy = -45f;
  public float m_maximumy = 45f;

  float m_rotationy = 0f;


  // use this for initialization
  void start () {
    // 防止 刚体影响 镜头旋转
    if (getcomponent<rigidbody>()) {
      getcomponent<rigidbody> ().freezerotation = true;
    }
  }

  // update is called once per frame
  void update () {
    if (m_axes == rotationaxes.mousexandy) {
      float m_rotationx = transform.localeulerangles.y + input.getaxis ("mouse x") * m_sensitivityx;
      m_rotationy += input.getaxis ("mouse y") * m_sensitivityy;
      m_rotationy = mathf.clamp (m_rotationy, m_minimumy, m_maximumy);

      transform.localeulerangles = new vector3 (-m_rotationy, m_rotationx, 0);
    } else if (m_axes == rotationaxes.mousex) {
      transform.rotate (0, input.getaxis ("mouse x") * m_sensitivityx, 0);
    } else {
      m_rotationy += input.getaxis ("mouse y") * m_sensitivityy;
      m_rotationy = mathf.clamp (m_rotationy, m_minimumy, m_maximumy);

      transform.localeulerangles = new vector3 (-m_rotationy, transform.localeulerangles.y, 0);
    }
  }
}

调用时，只需把该脚本绑定给物体即可。这里是绑定摄像机，以摄像机为第一人称视角转动。
