Unity3D选择本地图片并加载

本文实例为大家分享了Unity3D选择本地图片并加载的具体代码，供大家参考，具体内容如下

①找到System.Windows.Forms.dll：在unity的安装目录中找到它，如

E:\ProgramFiles(x86)\Unity\Editor\Data\Mono\lib\mono\2.0

②设置.NET 2.0集：Untiy默认是.NET 2.0 Subset。在Edit->Project Settings->Player->OtherSettings中修改

③任意打开一项目，新建Plugins文件夹，将找到的System.Windows.Forms.dll复制进去工程文件中(Project)

using UnityEngine;
using System.Collections;
using System;
using System.Windows.Forms;
using System.IO;
using UnityEngine.UI;
public class AddHead : MonoBehaviour {
 private Texture2D img=null;
 public Image image;
 public Sprite sprite;
// Use this for initialization
 void Start () {
 }
 // Update is called once per frame
 void Update () {
 }
 /*void OnGUI(){
 if (GUI.Button (new Rect (0, 0, 100, 20), "选择文件")) {
 }*/
 public void addhead(){
 OpenFileDialog od=new OpenFileDialog();
 od.Title="请选择头像图片";
 od.Multiselect=false;
 od.Filter="图片文件(*.jpg,*.png,*.bmp)|*.jpg;*.png;*.bmp";
 if(od.ShowDialog()==DialogResult.OK){
 //Debug.Log(od.FileName);
 StartCoroutine(GetTexture("file://"+od.FileName));
 }
 /*if (img != null) {
 //GUI.DrawTexture(new Rect(0,20,img.width,img.height),img);
 image.sprite=sprite;
 }*/
 }
 IEnumerator GetTexture(string url){
 WWW www = new WWW (url);
 yield return www;
 if (www.isDone && www.error == null) {
 img=www.texture;
 sprite=Sprite.Create(img,new Rect(0,0,img.width,img.height),new Vector2(0.5f,0.5f)); 
 image.sprite=sprite;
 //Debug.Log(img.width+" "+img.height);
 byte[] date=img.EncodeToPNG();
 }
 }
}
