Loading a sprite from URL C#
I'm trying to load an image from an URL, but none of the answers i found online apply to my problem. There is a good example in the unity docs, but it's javascript:
http://docs.unity3d.com/ScriptReference/WWW.LoadImageIntoTexture.html
I than need to load this sprite onto UI image element.
Please help,
Thanks
Solved thanks to the The Little Guy from unity forums!
public class ExampleClass : MonoBehaviour {
// The output of the image
public Image img;
// The source image
public string url = "http://images.earthcam.com/ec_metros/ourcams/fridays.jpg";
IEnumerator Start() {
WWW www = new WWW(url);
yield return www;
img.sprite = Sprite.Create(www.texture, new Rect(0, 0, www.texture.width, www.texture.height), new Vector2(0, 0));
}
}
Great answer. I did not know until now that Start (and other event handlers) can be made return IEnumerator and will be run as coroutines. Thats awesome!!
can be Resources.Load with URL? because I have a lot of pictures
Instead of Sprite.Create, you may want to use WWW.LoadImageIntoTexture to ensure your image isn't downsampled by QualitySettings (the difference is very noticeable at "Eighth Res").
www.LoadImageIntoTexture(img.mainTexture as Texture2D);
I wonder if there is any option to auto scale the aspect ratio of the downloaded image? In my case there is a placeholder with 800x600 pixels. So I want to keep the downloaded image's aspect ratio but cap its size to 800x600? Right now unity tries to fill my placeholder to its max...
EDIT: Ok found the solution by my self: At first I had not any source file in my image object. This caused the "preserve aspect ratio" button to not appear. After I inserted a placeholder image (before uploading one) the button appeared. Then just simply turn it on, now every time you upload a new image from url it keeps its aspect ratio! :)
