Stumbling on the tutorial

Troubleshooting import-assets
1

Hello,

I’m working on the tutorial and I am stuck on trying to load the unzipped contents of town.zip



This line of code:

[java]Spatial gameLevel = assetManager.loadModel(“Scenes/town/main.scene”);[/java]

I get this warning -


Feb 03, 2012 11:05:35 PM com.jme3.scene.plugins.ogre.SceneLoader load
WARNING: Cannot locate Scenes/town/main.material for scene Scenes/town/main.scene


And the following exception:

Any ideas? Thank you!

Did you ever figure out what the problem was? I am seeing the exact same thing - and the tutorials were going so smoothly up to this point! Also, in the next section were we are to right-click the main.scene and convert the scene to binary, I get the error:



No material file found for main.scene

A file named main.material should be in the same folder.

Press OK to import mesh only.



Even if I press OK, I don’t see any j3o file created…



This really seems simple - what are we doing wrong?

The zip is invalid, simple as that. It contains old files with name hacks and whatnot.

I did this tutorial a week ago and it worked first time so I don’t know why it wouldn’t work for some people but would for me…

Just to add - from what I remember (which could well be wrong, I’ve done a lot of other stuff since then) the tutorial read the data from the .zip file directly, no need to extract it. I just put town.zip in the root of the jmetests folder and everything worked.

Thanks - what seems weird is that accessing the zip directly, as in the first step of the exercise and mentioned by zarch, works. I guess reading assets from the zip is more tolerant somehow.
