NGUI实现滑动翻页效果实例代码

废话不多说了，直接给大家上干货了。

具体代码如下所示:

using unityengine;
using system.collections;
public class pageview : monobehaviour
{
const int item_num = 2; //总页数
const int page_width = 2048; //页宽
const float drag_speed = 0.5f; //翻页时间
const int drag_offect = 30; //滑动的起点和终点的差需大于这个数才能触发翻页效果
float beganx = 0; 
float begany = 0; //鼠标按下的坐标
int curindex = 1; //当前页数,默认为第一页
bool isplay = false; //是否正在翻页
bool ispress = false; //鼠标是否按下
bool ispagefoot = false; //当前是否处于页尾
bool ishomepage = true; //当前是否处于首页
string left = "left"; //左滑动画的name
string right = "right"; //右滑动画的name
gameobject[] item_objects;
// use this for initialization
void start ()
{
this.init ();
}
void init()
{
item_objects = new gameobject[item_num];
for(int i = 1; i <= item_num; ++i)
{
transform trans = this.transform.findchild("item" + i);
if(trans)
{
gameobject spr = trans.transform.findchild("background").gameobject;
spr.addcomponent<uieventlistener>();
uieventlistener.get(spr.gameobject).onpress = onpressevent;
}
item_objects[i - 1] = trans.gameobject;
}
}
//鼠标按下事件监听
void onpressevent(gameobject obj,bool isdown)
{
float endx;
float endy;
if (isdown) 
{
beganx = uicamera.lasttouchposition.x;
begany = uicamera.lasttouchposition.y;
ispress = true;
} else 
{
endx = uicamera.lasttouchposition.x;
endy = uicamera.lasttouchposition.y;
if (ispress) 
{
if(isplay == false)
{
if(endx - beganx > drag_offect)
{
if(ishomepage == false)
{
rightdrag();
}
}else if(endx - beganx < drag_offect){
if(ispagefoot == false)
{
leftdrag();
}
}
}
}
ispress = false;
}
}
//向左滑
void leftdrag()
{
isplay = true;
float x = this.transform.localposition.x - page_width;
tweenposition lefttween = tweenposition.begin (this.gameobject,drag_speed,new vector3(x,0,0));
lefttween.method = uitweener.method.easeinout;
lefttween.callwhenfinished = "callback";
lefttween.name = left;
lefttween.reset ();
}
//向右滑
void rightdrag()
{
isplay = true;
float x = this.transform.localposition.x + page_width;
tweenposition righttween = tweenposition.begin (this.gameobject,drag_speed,new vector3(x,0,0));
righttween.method = uitweener.method.easeinout;
righttween.callwhenfinished = "callback";
righttween.name = right;
righttween.reset ();
}
//动画结束的回调函数
void callback(uitweener tween)
{
isplay = false;
if (tween.name == left) 
{
curindex ++;
} else if (tween.name == right) 
{
curindex --;
}
if (curindex == 1) 
{
ishomepage = true;
}else
{
ishomepage = false;
}
if(curindex == item_num){
ispagefoot = true;
}else
{
ispagefoot = false;
}
}
}
