[1.9.4] Render Items in TESR

[Guest]

I am asking the TE for an ArrayList that contains 9 ItemStacks, the TE's inventory.

How can I apply a TRSRTransformation in the IBakedModel?

 

[Guest]

I am getting the hang of it right now, things are starting to make sense. I am gonna try stuff out tomorrow after school and I will report back.

This is what I have got right now:

The custom model:

            HashMap<Integer, ItemStack> stacks = new HashMap<Integer, ItemStack>();
            for (int i = 0; i < stackArray.length; ++i)

            quads.addAll(items.get(wrapper).getQuads(null, side, rand));
        }
        return quads;
    }
}

 

And the ModelLoader:

package XFactHD.thermalreactors.client.render.models;

import net.minecraft.client.renderer.block.model.*;

import net.minecraft.util.ResourceLocation;
import net.minecraftforge.client.model.*;
import net.minecraftforge.common.model.IModelState;

import javax.annotation.Nullable;
import java.util.Collection;
import java.util.List;

public enum  ModelLoaderLeadChest implements ICustomModelLoader
{
    INSTANCE;

    @Override
    public boolean accepts(ResourceLocation modelLocation)
    {
        return false;
    }

    @Override
    public IModel loadModel(ResourceLocation modelLocation) throws Exception
    {
        return new Model();
    }

    @Override
    public void onResourceManagerReload(IResourceManager resourceManager)
    {

    }

    @Override
    public String toString()
    {
        return "LeadChestLoader.INSTANCE";
    }

    public IModel getModel(ItemStack stack)
    {
        Item item = stack.getItem(); //Here I am trying to get the Model
        int meta = stack.getMetadata();
        IModel model = null;
        return model;
    }

    public class Model implements IModel
    {
        @Override
        public Collection<ResourceLocation> getDependencies()
        {
            return null;
        }

        @Override
        public IModelState getDefaultState()
        {
            return null;
        }

        @Override
        public Collection<ResourceLocation> getTextures()
        {
            return null;
        }

        @Override
        public IBakedModel bake(IModelState state, VertexFormat format, Function<ResourceLocation, TextureAtlasSprite> bakedTextureGetter)
        {
            return new BakedModel();
        }
    }

    public class BakedModel implements IBakedModel
    {
        @Override
        public ItemOverrideList getOverrides()
        {
            return null;
        }

        @Override
        public List<BakedQuad> getQuads(@Nullable IBlockState state, @Nullable EnumFacing side, long rand)
        {
            return null;
        }

        @Override
        public TextureAtlasSprite getParticleTexture()
        {
            return null;
        }

        @Override
        public boolean isAmbientOcclusion()
        {
            return true;
        }

        @Override
        public boolean isBuiltInRenderer()
        {
            return false;
        }

        @Override
        public boolean isGui3d()
        {
            return false;
        }

        @Override
        public ItemCameraTransforms getItemCameraTransforms()
        {
            return null;
        }
    }
}

 

My problem is now that I have no idea how to get the IModel from the information I can get from the ItemStack.

[Guest]

[*]I fixed that.

[*]I have no knowledge over the Items that implement the API interface that makes them compatible to the chest.

[*]For that method I need a ResourceLocation but I only have an ItemStack to get any information from and a ResourceLocation needs a modid

I don't know what the item model's file endings are.

Right, I was thinking the wrong way around.

You want

RenderItem#getItemModelWithOverrides

.

That method gives me an IBakedModel but I need an IModel to be able to bake it myself.

If not the Item's ModelResourceLocation, which one would the ModelLoader be for?

You don't bake it yourself.

I have to bake the models of the items that are in the chest myself to be able to apply a TRSRTransformation

[Guest]

If I gain access to the Item models I need, would it be possible to just replace the chest model with my custom chest model in the ModelBakeEvent and do the baking and stuff the way I have done it in the code I posted?

[Guest]

I just want to use ModelBakeEvent to replace the Chest model with the custom IBakedModel.

[Guest]

In the event, I take the chest's model, create a new IBakedModel (the one I posted before) and feed it with the old chest model. Then I put the new model into the registry. In the new model, I can easily handle the textures, etc.

 

This is what I tried to do to get the models to render:

private List<BakedQuad> constructContainedItems(HashMap<Integer, ItemStack> stacks, EnumFacing side, long rand, EnumFacing facing)
    {
        List<BakedQuad> quads = new ArrayList<BakedQuad>();
        IModel[] models = new IModel[9];
        for (int i = 0; i < 9; ++i)
        {
            ItemStack stack = stacks.get(i);
            if (stack == null)
            {
                continue;
            }

            PositionWrapper wrapper = new PositionWrapper(facing, i, stack);
            if (!items.containsKey(wrapper) || items.get(wrapper) == null)
            {
                models[i] = getModel(stack);
                //TRSRTransformation transformation = new TRSRTransformation(new Matrix4f(new Matrix3f(0, 0, 0, 0, 0, 0, 0, 0, 0), new Vector3f(0, 1, 0), 1F));
                TRSRTransformation transformation = new TRSRTransformation(new ItemTransformVec3f(new Vector3f(0, 0, 0), new Vector3f(0, 2, 0), new Vector3f(1, 1, 1)));
                    items.put(wrapper, models[i].bake(transformation, DefaultVertexFormats.ITEM, ModelLoader.defaultTextureGetter()));
            }

            quads.addAll(items.get(wrapper).getQuads(null, side, rand));
        }
        return quads;
    }

    private IModel getModel(ItemStack stack)
    {
        Item item = stack.getItem();
        Block block = Block.getBlockFromItem(item);
        ResourceLocation loc = block != null ? Block.REGISTRY.getNameForObject(block) : Item.REGISTRY.getNameForObject(item);
        ModelResourceLocation mloc = new ModelResourceLocation(loc.getResourceDomain() + ":" + loc.getResourcePath(), "inventory");
        IModel model;
        try
        {
            model = ModelLoaderRegistry.getModel(mloc);
        }
        catch (Exception e)
        {
            model = ModelLoaderRegistry.getMissingModel();
        }
        return model;
    }

 

I kinda works. I get a model but it's the missing model thingy. I checked the ModelResourceLocation and it is correct but stuff is still not working. Seems like a TESR is inavoidable without stuff becoming a huge pain in the back side.
