鼠标滚轮控制摄像头Unity 3d实现

有js版和c#（不会），可供大家选择

鼠标左键，摄像头旋转(c#版)

using UnityEngine;

using System.Collections;

public class control : MonoBehaviour {

public float roate_Speed=200.0f;//旋转速度

void Start () {

}

// Update is called once per frame

void Update () {

if (Input.GetMouseButton(0)){

//Debug.Log("射线取得对象");

float mousX = Input.GetAxis("Mouse X") * roate_Speed;//得到鼠标横向移动距离

float mousY = Input.GetAxis("Mouse Y") * roate_Speed;//得到鼠标纵向移动距离

// 绕Y轴旋转

transform.RotateAround (Vector3.zero, Vector3.up, mousX * Time.deltaTime);

// 绕x轴旋转（效果不是很好，使用时可注掉）

transform.RotateAround (Vector3.zero, Vector3.right, -mousY * Time.deltaTime);

}

}

}

鼠标滚轮调整摄像头与模型间距离

c#版

using UnityEngine;

using System.Collections;

public class carmera : MonoBehaviour {

public float minFov = 15f;

public float maxFov = 90f;

public float sensitivity = 10f;

// Use this for initialization

void Start () {

}

// Update is called once per frame

void Update () {

float fov = Camera.main.fieldOfView;

fov += -Input.GetAxis("Mouse ScrollWheel") * sensitivity;

fov = Mathf.Clamp(fov, minFov, maxFov);

Camera.main.fieldOfView = fov;

}

}

javascript版

#pragma strict

var viewSpeed=5;

// 与模型最近距离

var minFov=8.0;

// 与模型最远距离

var maxFov=100.0;

var fov:float;

function Start () {

}

function Update () {

if(Input.GetAxis("Mouse ScrollWheel")) {

// 从当前位置进行变更

fov = this.GetComponent.<Camera>().fieldOfView;

//Debug.Log("检测到滑轮"+Input.GetAxis("Mouse ScrollWheel"));

fov -= Input.GetAxis("Mouse ScrollWheel") * viewSpeed;

fov = Mathf.Clamp(fov, minFov, maxFov);

this.GetComponent.<Camera>().fieldOfView = fov;

}

}
