Loading a picture via url

Troubleshooting graphics
1

Hi all!

I’m trying to load a jpeg image from a url to be used as my texture (for, say, a Box).
I figured out I should probably be doing something with the UrlAssetInfo or UrlLocator classes, but I’m afraid I just can’t seem to be able to get this done.
It i very confusing to use (for example, if I register using "assetManager.registerLocator( X, UrlAssetInfo.class) - what goes in the “X” place? In the ZipLocator of the tutorials, we wrote “town.zip” but putting the url there doesn’t help).

I have been programming quite a lot with Java at college-level a few years ago, and so I’d be really comfortable if someone could point out a useful source for me to learn how to do this (if an answer isn’t readily available) - I’m feeling as if I’m searching in the dark and don’t know what I’m doing and that frustrates me :slight_smile:

Thanks!!!
Amir.

I think we would have to have an example URL to be specific enough.

Whatever your URL is, the “asset” will be resolved relative to it.

Look at this URL, for example:

How would you load that, as a texture, to a Material object?

Thank you!

My guess from the API:
assetManager.registerLocator( “http://i.telegraph.co.uk/multimedia/archive/02371”, UrlLocator.class );

Then load the image with the path: “karen-ann-jones_2371086k.jpg”

How I found this was to look at the javadoc for AssetManager, specifically:
http://hub.jmonkeyengine.org/javadoc/com/jme3/asset/AssetManager.html#registerLocator(java.lang.String,%20java.lang.Class)

Then I thought “Hmm… AssetLocator” and clicked on that.
http://hub.jmonkeyengine.org/javadoc/com/jme3/asset/AssetLocator.html

Then I saw UrlLocator… and clicked on that.
http://hub.jmonkeyengine.org/javadoc/com/jme3/asset/plugins/UrlLocator.html

You could also break the path down into a higher level directory or whatever and then include part of the path in the path to load the image.

Well,

I’ve been all around these pages, searched the javadoc like a nice java student and what I tried didn’t work.
My code looked exactly the same as what you’ve written, only for some stupid reason I was writing “UrlAssetInfo” instead of “UrlLocator”.
I changed that. Now it works :slight_smile:

Your post really helped me understand I was in the (sort of) right direction and eventually get it done - Thank you!

Amir,

Hmmm… surprised it even compiled with UrlAssetInfo.class there.

From the javadoc:

Indeed, the compiler forced me to cast the class to Class which should have prompted me something’s wrong, but I was so unsure of what I was doing I really didn’t think that I was just a step away from a working code.
Thanks again :slight_smile:
