Unity UGUI的Image（图片）组件的介绍及使用 - 简书
创建c#脚本
using System;
using System.Collections;
using System.Collections.Generic;
using System.IO;
using UnityEngine;
using UnityEngine.UI;public class LoadImageOnClick : MonoBehaviour
{// Start is called before the first frame updatepublic Image imageComponent;public Button button;void Start(){button = GetComponent<Button>();imageComponent = GetComponent<Image>();// 检查按钮是否成功获取if (button != null){button.onClick.AddListener(LoadAndShowImage);}else{Debug.LogError("Button component not found!");}}void LoadAndShowImage(){FileStream fs = new FileStream(@"C:\Users\Administrator\Pictures\mm\pics\005953_4.jpg", FileMode.Open, FileAccess.Read);fs.Seek(0, SeekOrigin.Begin);//游标的操作，可有可无byte[] bytes = new byte[fs.Length];//生命字节，用来存储读取到的图片字节try{fs.Read(bytes, 0, bytes.Length);//开始读取，这里最好用trycatch语句，防止读取失败报错}catch (Exception e){Debug.Log(e);}fs.Close();//切记关闭int width = 800;//图片的宽（这里两个参数可以提到方法参数中）int height = 800;//图片的高（这里说个题外话，pico相关的开发，这里不能大于4k×4k不然会显示异常，当时开发pico的时候应为这个问题找了大半天原因，因为美术给的图是6000*3600，导致出现切几张图后就黑屏了。。。Texture2D texture = new Texture2D(width, height);if (texture.LoadImage(bytes)){print("图片加载完毕 ");}else{print("图片尚未加载");}// 加载图片// Texture2D texture = Resources.Load<Texture2D>("YourImageName"); // 替换 "YourImageName" 为您的图片资源名称// 检查图片是否成功加载if (texture != null){print("显示加载的图片 ");imageComponent.sprite = Sprite.Create(texture, new Rect(0, 0, texture.width, texture.height), Vector2.zero);print("显示end ");}else{print("Failed to load image ");Debug.LogError("Failed to load image!");}}// Update is called once per framevoid Update(){}
}
自己创建gui组件：
操作步骤：
- 创建一个空对象，并将该脚本挂载到该对象上。
- 在场景中添加一个Canvas对象，并将Canvas的Render Mode设置为Screen Space - Overlay。
- 在Canvas下创建一个Image对象，并将Image组件拖拽到脚本的image字段上。
- 将要显示的图片资源拖拽到脚本的sprite字段上。
- 运行游戏，图片将会在场景中显示出来。
另一种方法：把脚本拖拽到Canvas下。
在脚本image属性中绑定脚本的变量。

面部的两个项目，需要再看看
