I got help getting a TESR to work for my shelf mod, which is my attempt at making some shelves my son saw on The Diamond Minecart's video about some mod I couldn't get to work on 1.8. Maybe this will help: https://github.com/RoseCotton/Forge-ModLoader-1.8-8.0.20.1023-1.8-src/ -RoseCotton

Hi, Andrewca. I made the same mod and am faced with the same problem. My kid just uses the mod in creative mode and right-clicks the mod spawner with the proper spawn egg to make the spawner he wants. I was hoping to override some magic function so the spawner cycles through the 16 monster options when clicked on, but haven't figured it out. I gave up at the point where I figured I'd have to make my own item. Did you figure it out? I plan to take a look at ItemMonsterPlacer this evening to see if the function it has for what happens when you right-click on a block covers the "if the block is a monster spawner, set the monster spawner moster type to the spawn egg type" or something. But even then I'm thinking I'd have to make my own monster spawner. What's up with the version 1.8 suggestion? I'm using 1.8 so it seems like I should be able to use NBT data or something to get this done...

omg! That's really exciting to see. I'm looking at the code now to try and figure out how to use it.

Sweet! it crashed! That means I actually made it into some new code. I'll debug it when I get back to the computer in a few hours... Here's the console data:

This is the current code: https://github.com/RoseCotton/Forge-ModLoader-1.8-8.0.20.1023-1.8-src/tree/e161a715577a1a22c8d32fdeb0e474c85601293f/src/main

Oh, I figured since my shelf holds four items I'd need to make a separate RenderItem for each one, but you're saying that I can get a RenderItem from calling this Minecraft.getMinecraft().getRenderItem() and the line of code should invoke all the rendering that happens in my RenderShelfItems class? Do I call that line of code in my ShelfTileEntity class or in some other class? Other calls like that are made inside of RenderManager, but I can't figure out how to 'register' my RenderShelfItems class with RenderManager so it gets called when all the others do.

Thanks, Grey Ghost. I looked at that a number of times but am getting the organization wrong in my head. Would I extend RenderItem a RenderShelfItems class or something? Currently I'm saying: public class RenderShelfItems extends Render Should I instead say: public class RenderShelfItems extends RenderItem ? Or do I create a new RenderItem object and call the renderItemModel method? I specify the location within the block for each of four ItemStacks that need to have an Item rendered in the block, so can I use renderItemModel(itemStackX) and somehow specify _where_ to render the item? mod: package com.rosecotton.shelvesmod;

I think I got all the bad words out of the comments this time.

I'm trying this: ibakedmodel = modelmanager.getModel(new ModelResourceLocation(entity.getStackInSlot(i).getUnlocalizedName(),"inventory"));

Really, what I want is an IBakedModel from either a RenderItem or an ItemStack. I just want to render an item within a block that is representative of the ItemStack held in a block's TileEntity. I'm copying a lot of code from the ItemFrame because it's the closest thing to what I want to do (i.e. render an item that is stored in a block). I'll post code if that helps, but I think I've narrowed down my question enough that it's probably not necessary. (this isn't one of those "my code's broke" questions).

I have an ItemStack type object and want to get its ModelResourceLocation. How is that done? itemStack1.getModelResourceLocation() would be awesome, but I don't think it exists. :\

Oh, I didn't realize that was an option. Thank you for the info. I reverted back to my code from Monday, which I'd luckily added to another post and am now backing up... I'll go take another swing at the rendering and see if I come up with the same problem. Then I'll learn what a working git repo is.

Maybe I don't understand since I'm also new, but why are you making this a TileEntity? Does it contain items or other data? Like, are you going to try to set items on the table? or is it just a block? If you do set stuff on the table and render it so it's visible, let me know how you do it!

This example is where I got most of my GUI code: https://github.com/TheGreyGhost/MinecraftByExample/tree/master/src/main/java/minecraftbyexample/mbe30_inventory_basic

Hi, All. I was trying to add code to render items on my shelf block when they're contained in the shelf's tile entity and I broke its container properties. Now, in the GUI, if I left-click on an item placed in the shelf, it disappears. If I right-click on an item in the shelf, it cuts the quantity in half, deletes half, and leaves 1/4 in the shelf and I can place 1/4 in my regular inventory. if I take that stack from inventory and put it back on the item in the shelf I got it from, I get 3/4 what I started with (so, like the item stack in inventory actually had 2x the quantity it was reporting). I'll say what I say each time I screw up my code... "I didn't change anything that should do this!" I've been combing through the code and can't find how I can even screw this up so bad. Can you find the blatant error? console data gives no clues. package com.rosecotton.shelvesmod; import net.minecraft.block.Block; import net.minecraft.client.Minecraft; import net.minecraft.client.renderer.entity.RenderItem;

I was hoping to find one. Even the example I'm looking at is from 1.7. Do you have any links to 1.8 tutorials for this?

hmmm...ok, I was hoping to get away from using that because it always led me down this trail of classes and methods until I got to arguments I couldn't figure out how to use, like RenderManager. So to render an Item (any) that represents an ItemStack (any) held in a slot in the TileEntity (for me, ShelfTitleEntity because I misspelled it) of a Block (mine is BlockShelf), I need to use ShelfRenderer.renderTileEntityAt(TileEntity tileentity, double d0, double d1, double d2, float f, int i) which extends TileEntitySpecialRenderer. The example I found creates a model, so ModelShelf shelf = new ModelShelf() (which extends model base), and that has a render method, shelf.render(TileEntity te, double x, double y, double z) that's called in renderTileEntityAt. So where do I create a ShelfRenderer object and call its renderTileEntityAt method? Do I do that when I close the GUI for the BlockShelf (i.e. after putting objects in or taking them out)?

UPDATE: I just stopped my mod from crashing when there's a null slot on my shelfblock (i.e. trying to render an empty item) by checking to make sure it's not null before doing the render. however, it still doesn't render my items and when I remove them from my ShelfBlock storage slots, they disappear. I must have broken something and not gotten the rendering right. package com.rosecotton.shelvesmod; import net.minecraft.client.renderer.entity.RenderEntityItem; import net.minecraft.entity.item.EntityItem; import net.minecraft.tileentity.TileEntity; public class RenderShelfTileEntity { public RenderShelfTileEntity(ShelfTitleEntity shelfTileEntity) { RenderEntityItem renderEntityItem = new RenderEntityItem(null, null); double x = ((TileEntity)shelfTileEntity).getPos().getX(); double y = ((TileEntity)shelfTileEntity).getPos().getY(); double z = ((TileEntity)shelfTileEntity).getPos().getZ(); EntityItem shelfEntityItem[] = new EntityItem[4]; for (int n = 0; n <4; n++) { if (shelfEntityItem[n] != null) { shelfEntityItem[n].setEntityItemStack(shelfTileEntity.itemStacks[n]); double xPlus = x + (double)((4+(n%2)*8)/16); double yPlus = y + (double)((2+(n/2)*6)/16); double zPlus = z + (double)((13-(n/2)*8)/16); renderEntityItem.func_177075_a(shelfEntityItem[n], xPlus, yPlus, zPlus, 0.0625f, 1.05f); } } } }

to insert code, type the following without the : [co:de] your code here [spoi:ler] your console data here [/spoi:ler] it's bbcode, there are reference websites around. p.s. I am having crashes while trying to render items on blocks in 1.8, too. It's hard.

UPDATE: trying to update inventory in my shelf, which is where I call my EntityItem renderer code, definitely causes mc to crash.

uh, oh.... if position data is type float, then I just calculated doubles for who-knows-what reason and passed them into I-don't-know-what in my renderEntityItem.func_177075_a(bunches-of-stuff).

I've put together something that I think might render my items (I at least want to see if it works) but I'm not sure from where to call my RenderShelfTileEntity class. package com.rosecotton.shelvesmod; import net.minecraft.client.renderer.entity.RenderEntityItem; import net.minecraft.entity.item.EntityItem; import net.minecraft.tileentity.TileEntity; public class RenderShelfTileEntity { public RenderShelfTileEntity(ShelfTitleEntity shelfTileEntity) { RenderEntityItem renderEntityItem = new RenderEntityItem(null, null); double x = ((TileEntity)shelfTileEntity).getPos().getX(); double y = ((TileEntity)shelfTileEntity).getPos().getY(); double z = ((TileEntity)shelfTileEntity).getPos().getZ(); EntityItem shelfEntityItem[] = new EntityItem[4]; for (int n = 0; n <4; n++) { shelfEntityItem[n].setEntityItemStack(shelfTileEntity.itemStacks[n]); double xPlus = x + (double)((4+(n%2)*8)/16); double yPlus = y + (double)((2+(n/2)*6)/16); double zPlus = z + (double)((13-(n/2)*8)/16); renderEntityItem.func_177075_a(shelfEntityItem[n], xPlus, yPlus, zPlus, 0.0625f, 1.05f); } } } Should I call this from the BlockShelf class, the ShelvesEventHandler (which currently doese nothing), or the ShelfTitleEntity class? I know I need to rename everything that says TitleEntity to TileEntity. :\

after stumbling around, the code that eclipse hasn't complained much about is: double x = ((TileEntity)shelfTileEntity).getPos().getX(); double y = ((TileEntity)shelfTileEntity).getPos().getY(); double z = ((TileEntity)shelfTileEntity).getPos().getZ(); we'll see if that works... I can't believe I just realized yesterday that it's TileEntity, not TitleEntity. I have a _lot_ of spelling errors in my code now. :\

Thanks, Draco; so, what I got out of that is that the position data is of type float. Right now I'm trying to figure out how to add in the block's coordinates but haven't found the translation between BlockPos and x, y, and z coordinates. I'll have a y offset for my items, too, so I'll add that into the for loop. I'm reading up on BlockPos and Entity and RenderEntityItem to figure out the position data. It's the rendering part I'm stuck on.

Hi, All. I'm still working on my shelves mod: I have my shelf block behaving properly, rendering and able to hold up to four item stacks. I'm trying to make the item models render on the shelves in the proper location. I want to say, For each itemStacks[0 through 3], take the ItemStack, find it's item model, render the item model in the proper location[0 through 3] relative to the block. I was looking at EntityItem, and I can set an item stack, but I'm not sure how to render it. Looking at RenderEntityItem, there are arguments of types RenderManager and RenderItem (and I'm not sure how to create those), but I'm thinking I should be able to find something that says "render this item in this location of this block" or something. sounds like something I might have to write... What structure would you use to get this done?
