[1.11.2] Best Way To Render Item Above Block

[LogicTechCorp]

I would like to render an Item that turns on top of my Block. I was looking around and saw that there a few different ways to achieve this. Which is the best and less resource intensive way to render the item?

[Kokkie]

I think the only way is to use a TESR... But idk and probably someone is going to tell me I'm wrong so...

And you would be wrong. You can use an IModel implementation to get the Item's model and bake it into your block.

There's a few forum threads on this already.

The Block has a TileEntity which has an inventory and allows it to store a single item. I would like for this Item to render on top of the Block like an item renders on the ground.

I have the Item rendering but it appears dark. What am I doing wrong?

 

public class RenderSummoningAltar extends TileEntitySpecialRenderer<TileEntitySummoningAltar>
{
    @Override
    public void renderTileEntityAt(TileEntitySummoningAltar altar, double x, double y, double z, float partialTicks, int destroyStage)
    {
        if(altar == null)
        {
            return;
        }

        ItemStack stack = altar.getInventory().getStackInSlot(0);

        if(!stack.isEmpty())
        {
            GlStateManager.pushMatrix();
            GlStateManager.translate(x + 0.5F, y + 1.225F, z + 0.5F);
            GlStateManager.disableLighting();

            GlStateManager.rotate((Minecraft.getSystemTime() / 720.0F) * (180.0F / (float)Math.PI), 0.0F, 1.0F, 0.0F);
            GlStateManager.scale(0.5F, 0.5F, 0.5F);
            GlStateManager.pushAttrib();

            RenderHelper.enableStandardItemLighting();
            Minecraft.getMinecraft().getRenderItem().renderItem(stack, ItemCameraTransforms.TransformType.FIXED);
            RenderHelper.disableStandardItemLighting();

            GlStateManager.popAttrib();
            GlStateManager.enableLighting();
            GlStateManager.popMatrix();
        }
    }
}

You should not be using a TESR to do this.

What should I be using?

I looked through the forum and cannot find a thread that discuses how to do that. Just a couple of questions: Would using what Draco suggested allow any item to work with this. Also, will the item be able to spin like a dropped item?

You never mentioned spinning. If you want it to spin, you need a TESR. I suggest you use FastTESR though. And yes, this works with any item.

Since you can't use GL calls in a FastTESR how would I go about rendering the item?

Look at AnimationTESR.

I have made some progress. Items now render but blocks do not. How would I render blocks and scale/rotate the model?

 

Current code:

public class RenderSummoningAltar extends FastTESR<TileEntitySummoningAltar>
{
    @Override
    public void renderTileEntityFast(TileEntitySummoningAltar altar, double x, double y, double z, float partialTicks, int destroyStage, VertexBuffer vertexRenderer)
    {
        ItemStack stack = altar.getInventory().getStackInSlot(0);

        if(!stack.isEmpty())
        {
            World world = altar.getWorld();

            IBakedModel model = Minecraft.getMinecraft().getRenderItem().getItemModelWithOverrides(stack, world, null);
            List<BakedQuad> quads = model.getQuads(null, null, 0L);

            for(BakedQuad quad : quads)
            {
                vertexRenderer.addVertexData(quad.getVertexData());
                vertexRenderer.putPosition(x, y + 1, z);
            }
        }
    }
}

You need to render the quads for all EnumFacings (and null), not just null.

I have blocks rendering now. There are a few issues: Blocks are rendered with color on them and the tops of blocks and items are transparent.

 

Current Code:

public class RenderSummoningAltar extends FastTESR<TileEntitySummoningAltar>
{
    @Override
    public void renderTileEntityFast(TileEntitySummoningAltar altar, double x, double y, double z, float partialTicks, int destroyStage, VertexBuffer vertexRenderer)
    {
        ItemStack stack = altar.getInventory().getStackInSlot(0);

        if(!stack.isEmpty())
        {
            World world = altar.getWorld();
            float time = (world.getTotalWorldTime() + partialTicks) / 20;

            IBakedModel model = Minecraft.getMinecraft().getRenderItem().getItemModelWithOverrides(stack, world, null);
            List<BakedQuad> quads;

            for(EnumFacing facing : EnumFacing.values())
            {
                quads = model.getQuads(null, facing, 0L);

                for(BakedQuad quad : quads)
                {
                    vertexRenderer.addVertexData(quad.getVertexData());
                    vertexRenderer.putPosition(x, y + 1.5D, z);
                }
            }

            quads = model.getQuads(null, null, 0L);

            for(BakedQuad quad : quads)
            {
                vertexRenderer.addVertexData(quad.getVertexData());
                vertexRenderer.putPosition(x, y + 1.5D, z);
            }
        }
    }
}

Anyone know how to fix this? Also, how do I get them to spin?

[Kokkie]

I don't think you can do that in a FastTESR...
