Change vanilla item model based off of name/lore

[Miclebrick]

I'm trying to make a mod that changes vanilla item model based off of its name or lore. But before I get to that, I'm trying to get it to even change the model in the first place! Nothing seems to happen. Am I missing anything?

Also, I noticed that MinecraftForgeClient.registerItemRenderer is not a thing in 1.9. Any reason for this?

There is a new way handling models in 1.9.

Here is a thread I made that helped me figure it out, might have what you are looking for.

[Miclebrick]

I'm sorry, I tried reading it, but I can't quite understand what exactly I need to do. Could you please explain to me?

[UberAffe]

Make a class that implements

ICustomModelLoader

. In

accepts

return true if it is the RL for your Item. In loadModel return a new IModel. In the IModel:

bake

: return a new instance of your ISmartItemModel.

getDependencies

/

getTextures

: Return ImmutableList.of() (the empty list).

getDefaultState

: Return TRSRTransformation.identiy.

 

Then register your loader using

ModelLoaderRegistry.registerLoader

in preInit. You now no longer need the bake event handler.

The difference for you is that you have a texture to return and you will probably be using IBakedModle instead of ISmartItemModel

[Miclebrick]

Ok, thanks, I'll try that!

[Miclebrick]

I don't have any access to the ItemStack here though, so how can I change it using the lore or name?

[Miclebrick]

Wouldn't an IBakedModel require me to model it in Techne? I want to use it with Minecraft json models, supplied by the resource pack.

[Miclebrick]

I figured out that you can use ItemOverrideList and handleItemState to get the itemstack info, but now I need to know how to generate a baked model from a model json file.

[UberAffe]

I haven't done that myself but minecrafts model loader also implements ICustomModelLoader so if you look around through that you should be able to see how they do it.

 

In case you don't know:

right click -> the 3 opens are a great way to trace through classes and method calls.

I made it turn to an apple when named Apple, but it crashes when it's a non-apple diamond sword!

 

EDIT: Whoops, forgot to pastebin!

If I handle the bake event, would I be able to do the original method?

[Miclebrick]

http://www.minecraftforge.net/forum/index.php/topic,37398.msg197123.html#msg197123 they were successfully able to use it in 1.9, so I do believe it should work in 1.9. Perhaps it doesn't work because I'm using it with vanilla items?

[Miclebrick]

Is it possible to specify custom item overrides based off of nbt data?

[Miclebrick]

It seems the problem with ItemMeshDefinition is that getModelLocation() is never called. I can't figure out why.

[Miclebrick]

I discovered in ItemModelMesher:

 

public IBakedModel getItemModel(ItemStack stack)

    {

        Item item = stack.getItem();

        IBakedModel ibakedmodel = this.getItemModel(item, this.getMetadata(stack));

 

        if (ibakedmodel == null)

        {

            ItemMeshDefinition itemmeshdefinition = (ItemMeshDefinition)this.shapers.get(item);

 

            if (itemmeshdefinition != null)

            {

                ibakedmodel = this.modelManager.getModel(itemmeshdefinition.getModelLocation(stack));

            }

        }

 

        if (ibakedmodel == null)

        {

            ibakedmodel = this.modelManager.getMissingModel();

        }

 

        return ibakedmodel;

    }

 

Does that mean that it's only called for nonexistent meshes? (It checks if baked mesh is null first)

[Miclebrick]

I'm going to try to use reflection to remove the model first.

[UberAffe]

If you know what the model should be during pre-post Initialization you should be able to just over write the original locations.

[Miclebrick]

@SuppressWarnings("unchecked")

private void removeItemFromMesher(Item item, int meta) {

try {

Field field1 = ItemModelMesher.class.getDeclaredField("simpleShapesCache");

field1.setAccessible(true);

Map<Integer, IBakedModel> simpleShapesCache = (Map<Integer, IBakedModel>) field1.get(getMesher());

simpleShapesCache.remove(getIndex(item, meta));

field1.set(getMesher(), simpleShapesCache);

Field field2 = ItemModelMesher.class.getDeclaredField("simpleShapes");

field2.setAccessible(true);

Map<Integer, ModelResourceLocation> simpleShapes = (Map<Integer, ModelResourceLocation>) field2.get(getMesher());

simpleShapes.remove(getIndex(item, meta));

field2.set(getMesher(), simpleShapes);

} catch (NoSuchFieldException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (SecurityException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (IllegalArgumentException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (IllegalAccessException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

 

 

I tried doing this on postinit, but it did nothing.

I GOT IT TO WORK WITH ICUSTOMMODELLOADER!

 

It now looks like a potato unless it is named Apple, in which case it looks like an apple. It works as expected

 

My new code: http://pastebin.com/bQAWSUVx

 

Now that I know how, I can use that same concept to make an actual system for it. (Code is very hacky, so anyone reading this shouldn't copy and paste )
