我要评论本文实例为大家分享了unity ugui实现滑动翻页效果的具体代码，供大家参考，具体内容如下
这个问题真的是老生常谈的事情了，不过在这里还是要说一下，以便以后之需
首先看一下效果图
最后在content下面是一些image
using unityengine;
using system.collections;
using unityengine.ui;
using system.collections.generic;
using unityengine.eventsystems;
using system;
public class pageview : monobehaviour, ibegindraghandler, ienddraghandler {
scrollrect rect; //滑动组件
//public scrollrect rect2; //滑动组件2
private float targethorizontal = 0; //滑动的起始坐标
private bool isdrag = false; //是否拖拽结束
private list<float> poslist = new list<float> ();//求出每页的临界角，页索引从0开始
private int currentpageindex = -1;
public action<int> onpagechanged;
private bool stopmove = true;
public float smooting = 4; //滑动速度
public float sensitivity = 0;
private float starttime;
private float startdraghorizontal;
void awake () {
// rect = rect2;
rect = transform.getcomponent<scrollrect> ();
// rect2 = transform.getcomponent<scrollrect>();
float horizontallength = rect.content.rect.width - getcomponent<recttransform> ().rect.width;
//float horizontallength2 = rect2.content.rect.width - getcomponent<recttransform>().rect.width;
poslist.add (0);
for(int i = 1; i < rect.content.transform.childcount - 1; i++) {
poslist.add (getcomponent<recttransform> ().rect.width * i / horizontallength);
}
poslist.add (1);
}
void update () {
if(!isdrag && !stopmove) {
starttime += time.deltatime;
float t = starttime * smooting;
rect.horizontalnormalizedposition = mathf.lerp (rect.horizontalnormalizedposition , targethorizontal , t);
// rect2.horizontalnormalizedposition = mathf.lerp(rect2.horizontalnormalizedposition, targethorizontal, t);
if (t >= 1)
stopmove = true;
}
}
public void pageto (int index) {
if(index >= 0 && index < poslist.count) {
rect.horizontalnormalizedposition = poslist[index];
setpageindex(index);
} else {
debug.logwarning ("页码不存在");
}
}
private void setpageindex (int index) {
if(currentpageindex != index) {
currentpageindex = index;
if(onpagechanged != null)
onpagechanged (index);
}
}
public void onbegindrag (pointereventdata eventdata) {
isdrag = true;
startdraghorizontal = rect.horizontalnormalizedposition;
// startdraghorizontal = rect2.horizontalnormalizedposition;
}
public void onenddrag (pointereventdata eventdata) {
float posx = rect.horizontalnormalizedposition;
posx += ((posx - startdraghorizontal) * sensitivity);
posx = posx < 1 ? posx : 1;
posx = posx > 0 ? posx : 0;
int index = 0;
float offset = mathf.abs (poslist[index] - posx);
for(int i = 1; i < poslist.count; i++) {
float temp = mathf.abs (poslist[i] - posx);
if(temp < offset) {
index = i;
offset = temp;
}
}
setpageindex (index);
targethorizontal = poslist[index]; //设置当前坐标，更新函数进行插值
isdrag = false;
starttime = 0;
stopmove = false;
}
}
最后看一下，怎么设置的：
剩下的就没有什么了。
