UnityWebRequest加载网络图片当作贴图给物体

一、用UnityWebRequest加载网络图片并且当作Sprite给Image和贴图给3D物体

二、代码

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Networking;
using UnityEngine.UI;
public class UNityWebTest : MonoBehaviour
{
string url = @"http://pic37.nipic.com/20140113/8800276_184927469000_2.png";
void Start()
{
StartCoroutine(DownSprite());
StartCoroutine(DownMaterial());
}
IEnumerator DownSprite()
{
UnityWebRequest wr = new UnityWebRequest(url);
DownloadHandlerTexture texDl = new DownloadHandlerTexture(true);
wr.downloadHandler = texDl;
yield return wr.SendWebRequest();
int width = 1920;
int high = 1080;
if (!wr.isNetworkError)
{
Texture2D tex = new Texture2D(width, high);
tex = texDl.texture;
Sprite sprite = Sprite.Create(tex, new Rect(0, 0, tex.width, tex.height), new Vector2(0.5f, 0.5f));
transform.GetComponent().sprite = sprite;
}
}
IEnumerator DownMaterial()
{
UnityWebRequest wr = new UnityWebRequest(url);
DownloadHandlerTexture texDl = new DownloadHandlerTexture(true);
wr.downloadHandler = texDl;
yield return wr.SendWebRequest();
if (!wr.isNetworkError)
{
Texture2D tex = null;
tex = texDl.texture;
GameObject.Find("Cube").GetComponent().material.mainTexture = tex;
}
}
private void OnApplicationQuit()
{
StopAllCoroutines();
}
}
