I'm trying to follow this tutorial but I got stuck at the part where you assign a model and texture to an item and I need someone to take a look at my code. It doesn't throw any exceptions but I get the default texture either way.

In your ItemRenderRegister.java

 

change line 16, Minecraft.getMinecraft().getRenderItem().getItemModelMesher().register(item, 0, new ModelResourceLocation("mapoverlay:item/tutorial_item", "inventory"));

 

into: ModelLoader.setCustomModelResourceLocation ( item, 0, new ModelResourceLocation("mapoverlay:item/tutorial_item", "inventory") );

And make sure you're calling setCustomModelResourceLocation in or under preInit.

The debugger is a powerful and necessary tool in any IDE, so learn how to use it. You'll be able to tell us more and get better help here if you investigate your runtime problems in the debugger before posting.

That just gives me a NullPointerException:

And make sure you're calling setCustomModelResourceLocation in or under preInit.

 

That does, too:

I believe your assets should be in your resources folder, not java.

 

Can you post the full path the files should be in?

/forge/src/main/java/assets/mapoverlay/textures/item/tutorial_item.png

and

/forge/src/main/java/assets/mapoverlay/models/item/tutorial_item.json

are the only locations where the game will start without throwing any exceptions.

Posted

You would want it to be

/forge/src/main/resources/assets/mapoverlay/models/item/tutorial_item.json

 

If it's throwing an error, what's it telling you?

Here's the exception I'd get:

[22:16:05] [Client thread/INFO] [FML]: Injecting itemstacks

 

 

Edit: I've moved the files to the path you posted and it's doing the same as in my original location, no exceptions but the assets don't show up.

Try changing

ModelResourceLocation("mapoverlay:item/tutorial_item", "inventory"));

 

to

 

ModelResourceLocation("mapoverlay:tutorial_item", "inventory"));

 

Looking at a simple item I made, I didn't specify the "item/" in theModelResourceLocation call.

Posted

Alright, it's working now. Here's the summary for anyone coming from Google six months later:

 

* The call to ModItems.createItems() goes in CommonProxy.preInit(), the call to ItemRenderRegister.registerItemRenderer() goes in ClientProxy.init() after calling the base method.

 

* I completely missed something in createItems(), can you spot it?

 

(...)
    public static Item tutorialItem;
    
    public static final void createItems() {
    	Item tutorialItem = new BasicItem("tutorial_item");
(...)

 

Fuck me ...

 

* Now the game would start up, but still displayed the error texture. Turns out that this code proposed upthread

 

ModelLoader.setCustomModelResourceLocation ( item, 0, new ModelResourceLocation("mapoverlay:item/tutorial_item", "inventory") );

 

doesn't actually work, so I changed it back into the code based on the the tutorial and there you go, working model & texture:

 

Minecraft.getMinecraft().getRenderItem().getItemModelMesher()
    .register(item, 0, new ModelResourceLocation("mapoverlay:tutorial_item", "inventory"));

I was stuck on same tutorial and came to here. What fixed it for me was making sure that ItemRenderRegister.registerItemRenderer()  was in preInit() under ClientProxy.java. And then I was able to follow as others suggested to use "ModelLoader.setCustomModelResourceLocation".

 

Thanks all for providing input, it definitely helps for others down the road.
