Hi,

 

I'm developing a custom tileentity with a guiless inventory. You can put items on it's top side and get them out of there. I have two problems here. The first and more important problem is that i can't get the world to spawn the item when the player interacts with the block. I call world.spawnEntity on the server side with an EntityItem filled with the ItemStack. On client, the item pops up and disappears instantly, without me getting the item in the player inventory. The corresponding code looks like this:

 

    public boolean onPlayerRightClickOnTop(EntityPlayer player, float hitX, float hitZ) {
        if (world.isRemote) {
            return false;
        }

        int i = hitX > 0.33f ? (hitX > 0.66f ? 2 : 1) : 0;
        int j = hitZ > 0.33f ? (hitZ > 0.66f ? 2 : 1) : 0;

        ItemStack activeStack = player.getHeldItemMainhand();

        if (player.isSneaking()) {
            if (!inventory[i][j].isEmpty()) {
                EntityItem entityItem = new EntityItem(world, pos.getX() + hitX, pos.getY() + 1.2, pos.getZ() + hitZ, inventory[i][j]);
                world.spawnEntity(entityItem);
                inventory[i][j].setCount(0);
                sendDataToClients();
                return true;
            } else if (!activeStack.isEmpty()) {
                inventory[i][j] = activeStack.copy();
                activeStack.setCount(0);
                sendDataToClients();
                return true;
            }
        } else if (!activeStack.isEmpty()) {
            if (inventory[i][j].isEmpty()) {
                inventory[i][j] = activeStack.splitStack(1);
                sendDataToClients();
                return true;
            } else if (inventory[i][j].isItemEqual(activeStack)
                    && inventory[i][j].getCount() < inventory[i][j].getMaxStackSize()) {
                inventory[i][j].setCount(inventory[i][j].getCount()+1);
                activeStack.splitStack(1);
                sendDataToClients();
                return true;
            }
        }

        return false;
    }

 

 

My second problem is that the items rendered on the block look totally dark, no lightning at all. I tried it with and without the lightning related lines, but i noticed no change. The rendering code is like this:

 

    @Override
    public void render(TileEntityCraftingPillar te, double x, double y, double z, float partialTicks, int destroyStage, float alpha) {
        super.render(te, x, y, z, partialTicks, destroyStage, alpha);

        EntityItem entityItem = new EntityItem(getWorld());
        entityItem.hoverStart = 0;

        for (int i = 0; i < 3; ++i) {
            for (int j = 0; j < 3; ++j) {
                if (!te.getItemStackAt(i, j).isEmpty()) {
                    GlStateManager.pushMatrix();

                    GlStateManager.translate(x + 1./6 + 1./3*i, y + 1, z + 1./6 + 1./3*j);
                    //GlStateManager.translate(-x, -y, -z);
                    GlStateManager.scale(0.33, 0.33, 0.33);

                    GlStateManager.pushAttrib();
                    RenderHelper.enableStandardItemLighting();

                    entityItem.setItem(te.getItemStackAt(i, j));
                    Minecraft.getMinecraft().getRenderManager().doRenderEntity(entityItem,
                            0, 0, 0, 0, 0, false);
                    //RenderEntityItem
                    //Minecraft.getMinecraft().getRenderItem().renderItem(te.getItemStackAt(i, j), ItemCameraTransforms.TransformType.FIXED);

                    RenderHelper.disableStandardItemLighting();
                    GlStateManager.popAttrib();

                    GlStateManager.popMatrix();
                }
            }
        }
    }

Thank you for your help in advance!

I will watch it when i get home, currently i'm working from mobile internet and it's expensive O_O
By the way, i managed to fix the spawning issue. I passed the reference of the inventory itemstack to the entity, instead of copying it. So when i set count in the inventory to zero, it caused the entity to set it's count to zero as well. I hope i can fix the lightning issue after watching the video.

I'm the co-developer of this mod and we tried it on 3 different versions (1.12, 1.10.2.2016, 1.10.2.recommended) but the items are still dark, we followed the video as close as we could with no luck.

 

Here is the code, it would be nice if someone could try it out/take a look: https://github.com/Dawars/CraftingPillars

Don't create a new EntityItem each frame. Especially because you are using it only to re-route to the code that renders the ItemStack in pretty much the same way you've commented out.

As you've said the lightmap coordinates are incorrect. Set them manually with OpenGlHelper.setLightmapTextureCoords. The first parameter is the texture unit(OpenGlHelper.lightmapTexUnit), second and third are your lightmap coordinates. Do not forget to reset them back to what they were after you are done - their current values are stored at OpenGlHelper.lastBrightnessX/Y

Ooookay, so I have overriden the following deprecated method and now the lighting is working as expected: 

 @Override
    public boolean isOpaqueCube(IBlockState state) {
        return false;
    }

How can I find a potential non-deprecated method for this? (and isFullCube).

 

Also I found the isVisuallyOpaque method, does it do anything?
