最近接了个用unity做全景图的活,我的想法是在unity内建一个球,将shader选为Mobile/particles/Alpha Blended,然后将做好的全景图贴上去就OK了,下面贴上一段摄像机放大缩小的代码,怕自己忘了..参考了部分网上的代码
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
public class Test01 : MonoBehaviour
{
public float moveSpeed = 1;//物体旋转速度
public GameObject target;
private Vector2 oldPosition;
private Vector2 oldPosition1;
private Vector2 oldPosition2;
private float distance = 0;
private bool flag = false;
//摄像头的位置
private float x = 0f;
private float y = 0f;
//左右滑动移动速度
public float xSpeed = 250f;
public float ySpeed = 120f;
//缩放限制系数
public float yMinLimit = -360;
public float yMaxLimit = 360;
//是否旋转
private bool isRotate = true;
//计数器
private float count = 0;
public static Test01 _instance;
//初始化游戏信息设置
void Start()
{
_instance = this;
Vector3 angles = transform.eulerAngles;
x = angles.y;
y = angles.x;
if (GetComponent< Rigidbody >())
GetComponent< Rigidbody >().freezeRotation = true;
}
// Update is called once per frame
void Update()
{
if (isRotate)
{
target.transform.Rotate(Vector3.down, Time.deltaTime * moveSpeed,Space.World);
}
if (!isRotate)
{
count += Time.deltaTime;
if (count > 5)
{
count = 0;
isRotate = true;
}
}
//触摸类型为移动触摸
if (Input.GetMouseButton(0))
{
//根据触摸点计算X与Y位置
x += Input.GetAxis("Mouse X") * xSpeed *Time.deltaTime;
y -= Input.GetAxis("Mouse Y") * ySpeed * Time.deltaTime;
isRotate = false;
}
//判断鼠标滑轮是否输入
float temp = Input.GetAxis("Mouse ScrollWheel");
if (temp!=0)
{
if (temp>0)
{
// 这里的数据是根据我项目中的模型而调节的，大家可以自己任意修改
if (distance > -15)
{
distance -= 0.5f;
}
}
if (temp 360)
angle -= 360;
return Mathf.Clamp(angle, min, max);
}
}
