Retrieving a Texture from an HTTP Server (GET)


Important: UNet is a deprecated solution, and a new Multiplayer and NetworkingThe Unity system that enables multiplayer gaming across a computer network. More info See in Glossary Solution (Netcode for GameObjects) is under development. For more information and next steps see the information on the Unity Netcode for GameObjects website.

To retrieve a Texture file from a remote server, you can use UnityWebRequest.Texture. This function is very similar to UnityWebRequest.GET but is optimized for downloading and storing textures efficiently.

This function takes a single string as an argument. The string specifies the URL from which you wish to download an image file for use as a Texture.

Details

This function creates a UnityWebRequest and sets the target URL to the string argument. This function sets no other flags or custom headers.
This function attaches a DownloadHandlerTexture object to the UnityWebRequest. DownloadHandlerTexture is a specialized Download Handler which is optimized for storing images which are to be used as Textures in the Unity Engine. Using this class significantly reduces memory reallocation compared with downloading raw bytes and creating a Texture manually in script.
By default, this function does not attach an Upload Handler. You can add one manually if you wish.

Example

using UnityEngine;
using System.Collections;
using UnityEngine.Networking;
 
public class MyBehaviour : MonoBehaviour {
    void Start() {
        StartCoroutine(GetTexture());
    }
 
    IEnumerator GetTexture() {
        UnityWebRequest www = UnityWebRequestTexture.GetTexture("https://www.my-server.com/image.png");
        yield return www.SendWebRequest();

        if (www.result != UnityWebRequest.Result.Success) {
            Debug.Log(www.error);
        }
        else {
            Texture myTexture = ((DownloadHandlerTexture)www.downloadHandler).texture;
        }
    }
}

Alternatively, you can implement GetTexture using a helper getter:

    IEnumerator GetTexture() {
        UnityWebRequest www = UnityWebRequestTexture.GetTexture("https://www.my-server.com/image.png");
        yield return www.SendWebRequest();

        Texture myTexture = DownloadHandlerTexture.GetContent(www);
    }
