Unity previous page Next switch function implementation source (for reference Only)

In the project we sometimes need to implement a switch to the next page of the picture, switch on the next song, and so on similar functions. Here wrote a simple implementation of the source code (for reference only), If there is a better way to welcome the proposed, common Progress ~

To switch the previous page to the next picture as an example:

usingunityengine;usingsystem.collections;usingunityengine.ui;
 public classPanoramamanager:monobehaviour {//Image Storage Arraytexture2d[]arr; //Next button Count index    inti =1; //Previous button Count index    intJ =-1; //switch to the next one     publicIEnumerator setnexttexture () {if(here's How you can determine the criteria for interacting with the next page of the ui) {if(i < Arr.) Length-1)            {                //the things you want to do. .. J= i-1; I++; }            Else            {                //give the wrong hint That's already the last one                ...            } }    }        //Toggle the previous one     publicIEnumerator setbeforetexture () {if(here's How you determine the criteria for interacting with the previous page Ui) {if(j >=0)            {                //the things you want to do. .. I= j +1; J--; }            Else            {                //give the wrong hint That's already the first one                ...            } }    }}
