本文实例为大家分享了unity3d实现列表分页效果的具体代码，供大家参考，具体内容如下

using system.collections.generic;
using unityengine;
 
public class page : monobehaviour {
  public list<string> tips = new list<string>();
  public texture2d detailimg1;
  public texture2d detailimg2;
 
  private int pagecount = 0;//当前记录所需页数
  private static int currentpage = 1;//当前页码
 
  void ongui() {
    pagecount = mathf.ceiltoint(tips.count / 8.0f);//计算当前的页码总数
    int m_count = 0;//计算当前页的记录数
    if (currentpage != pagecount)//判断是否是最后一页，若不是则每页绘制8条记录
    {
      m_count = 8;
    }
    else {
      if (mathf.ceiltoint((tips.count + 1) / 8.0f) > pagecount)//判断最后一页是否有8条记录
      {
        m_count = 8;
      }
      else
      {
        m_count = tips.count % 8;//计算最后一页的记录数
      }
    }
 
    for (int i = 0; i < m_count; i++)
    {
      if (i % 2 == 0)
      {
        gui.drawtexture(new rect(268, 253 + i * 36, 487, 36), detailimg1);
      }
      else
      {
        gui.drawtexture(new rect(268, 253 + i * 36, 487, 36), detailimg2);
      }
      gui.label(new rect(310, 253 + i * 36, 300, 36), tips[(currentpage - 1) * 8 + i]);
    }
    //超过一页内容时，显示页码跳转
    if (pagecount > 1) {
      float temp = screen.width / 2 - pagecount / 2 * 20;
      for (int i = 1; i <= pagecount; ++i) {
        //更改按钮样式
        if (currentpage == i)
        {
          gui.backgroundcolor = color.red;
        }
        else
        {
          gui.backgroundcolor = color.white;
        }
        //绘制按钮
        if (gui.button(new rect(temp + 20 * i, 600, 20, 20), i.tostring())) {
          currentpage = i;//更改当前选中的页
        }
      }
    }
  }
}
