1.资源加载案例:

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI; using System; public class LodingPanel : MonoBehaviour { private Transform _Transform;//存储当前对象的Transform组件信息. private Image _Center;//存储需要显示进度的图片. private Text _Num;//存储需要显示进度数值的文本. private float loadingValue = 0;//记录每次累加的数值. void Start () { _Transform = gameObject.GetComponent<Transform>(); _Center = _Transform.Find("Loding/Center").GetComponent<Image>(); _Num = _Transform.Find("Loding/Num").GetComponent<Text>(); _Center.fillAmount = 0; _Num.text = ""; StartCoroutine("SetLoadingValue"); } /// <summary> /// 设置进度条数值. /// </summary> IEnumerator SetLoadingValue() { while (loadingValue < 0.95f) { loadingValue += UnityEngine.Random.Range(0.01f, 0.1f);//随机数值并累加 fillAmount属性取值0-1 . _Center.fillAmount = loadingValue; _Num.text = Math.Round(loadingValue, 2) * 100 + "%";//保留两位. yield return new WaitForSeconds(0.2f);//等待的秒数. } _Center.fillAmount = 1; _Num.text = "100%"; Debug.Log("进度条加载完毕."); } }项目素材地址:链接: https://pan.baidu.com/s/1hQyEzjvQl-_v293UkY0b4g 提取码: m52p 点击链接提取素材
2.游戏签到案例:
以下是各个UI元素布局结构图:
把Item拖拽到Resources文件夹下面，把LitJson存放到Plugins文件夹下(存放在这个文件夹下的资源会优先编译)，因为我们要使用Json完成对象的转换.

2.游戏商城案例:
需要设置的地方我都用红框框选住了，各位照着做即可，整个案例布局总共26张截图。
以下是各个UI元素布局结构图:
在本案例中共存在三个预制体它们的名字分别为:Tab、Content、ContentItem。
