Hey all.

 

I'm working on a mod which supports asset packs; third party content users can add without any editing to the code.

 

I've got the basic asset system working now - The mod will detect .txt files to create an item, and it can find static textures to use with that item and load them into the game. My issue comes when I try to use a custom model.

 

Here's the code I use to add my resource packs to the game:

@Override
public void reflectResourcePackMethods() {
	AdvancedArmoury.println("Reflecting in and loading resources");
	List<IResourcePack> assetPacks = ObfuscationReflectionHelper.getPrivateValue(Minecraft.class, Minecraft.getMinecraft(), "defaultResourcePacks", "field_110449_ao");
	List<File> assets = getAssetPackList();

	for (File file : AdvancedArmoury.assetDir.listFiles()) {
		try {
			if (AdvancedArmoury.isZipFile(file)) {
				assetPacks.add(new FileResourcePack(file));
			}
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}

 

- This works just fine for a normal texture like most items have. My only issue is with loading an .obj model, which throws this stack on loading the game:

If I place the model in the normal resource location for the mod (IE, within the .jar) it works fine - so I know the actual rendering isn't an issue. Also, the asset file structure between .jar and asset pack is the same, and normal textures load in either of them, so I know it's not a typo in my path. Rendering happens after my asset packs are registered (in the post init- whereas asset packs are registered in init)

 

Asset pack's path, just for my own sanity so I know it's not a typo:

 

I can't think of any reason this may be happening. One thing that may be worth noting is that when the game fully loads, I get this notice in the log:

despite the fact that the assets do in fact load and show up in game. Could that hold any clues? My only thought here is maybe as I'm using FileResourcePack instead of my own custom implementation of IResourcePack to add in assets; would that somehow cause it to ignore .obj files?

 

Bump, anyone got any ideas?

Still having problems here and it makes me feel sad inside
