UnityWebRequestTexture.GetTexture

Parameters

Returns

UnityWebRequest A UnityWebRequest properly configured to download an image and convert it to a Texture.

Description

Create a UnityWebRequest intended to download an image via HTTP GET and create a Texture based on the retrieved data.

Use UnityWebRequestTexture.GetTexture to retrieve a Texture file from a remote server. This function is very similar to UnityWebRequest.Get, but is optimized for downloading and storing textures efficiently. It creates a UnityWebRequest and sets the target URL to the one specified as a string or uri object in the uri argument. No other flags or custom headers are set.

This method attaches a DownloadHandlerTexture object to the UnityWebRequest. DownloadHandlerTexture is a specialized DownloadHandler optimized for storing images that are to be used as textures in the Unity Engine. Using this class significantly reduces memory reallocation compared to downloading raw bytes and creating a texture manually in script. In addition, texture conversion is performed on a worker thread.

This method attaches no UploadHandler to the UnityWebRequest.

The texture is created as if it stores color data. Only JPG and PNG formats are supported.

Parameters

Returns

UnityWebRequest A UnityWebRequest properly configured to download an image and convert it to a Texture.

Description

Create a UnityWebRequest intended to download an image via HTTP GET and create a Texture based on the retrieved data.

Same as an overload with only uri parameter, except that it allows more control over the properties of texture that will be created. For example, using this overload you can disable creation of mipmaps or use linear color space.

using System.Collections;
using UnityEngine;
using UnityEngine.Networking;

public class NewMonoBehaviourScript : MonoBehaviour
{
   void Start()
   {
       StartCoroutine(GetText());
   }

    IEnumerator GetText()
    {
        // Use linear color space and reduce memory usage by disabling mipmaps and ability to read pixels
        var parameters = DownloadedTextureParams.Default;
        parameters.readable = false;
        parameters.mipmapChain = false;
        parameters.linearColorSpace = true;
        using (UnityWebRequest uwr = UnityWebRequestTexture.GetTexture("https://www.my-server.com/myimage.png", parameters))
        {
            yield return uwr.SendWebRequest();

            if (uwr.result != UnityWebRequest.Result.Success)
            {
                Debug.Log(uwr.error);
            }
            else
            {
                // Get downloaded asset bundle
                var texture = DownloadHandlerTexture.GetContent(uwr);
            }
        }
    } 
}
