Update for forge! [ItemStack(Block) rendering bassed on NBT of the ItemStack]

Start new topic

Posted May 7, 201411 yr

I have a problem with the way minecraft renders blocks!

I need a way to give a block an texture from another block bassed on NBT.

I find one, but that only works if forge does implement the codes below here.

These add things.

package net.minecraft.client.renderer; RenderBlocks.java

public void renderBlockAsItem(Block p_147800_1_, int p_147800_2_, float p_147800_3_, ItemStack p_147800_4_)

{

renderBlockAsItem(Block.getBlockFromItem(p_147800_1_.getBlockRenderingInInventory(p_147800_4_).getItem()), p_147800_1_.getBlockRenderingInInventory(p_147800_4_).getItemDamage(), p_147800_3_);

}

package net.minecraft.block; Block.java

public ItemStack getBlockRenderingInInventory(ItemStack itemstack)

{

return itemstack;

}

These change things, Look at >//Changed< for changes.

package net.minecraft.client.renderer; ItemRenderer.java

public void renderItem(EntityLivingBase par1EntityLivingBase, ItemStack par2ItemStack, int par3, ItemRenderType type)

{

if (customRenderer != null)

{

texturemanager.bindTexture(texturemanager.getResourceLocation(par2ItemStack.getItemSpriteNumber()));

ForgeHooksClient.renderEquippedItem(type, customRenderer, renderBlocksIr, par1EntityLivingBase, par2ItemStack);

}

Read the EAQ before posting! OR ELSE!

This isn't building better software, its trying to grab a place in the commit list of a highly visible github project.

Don't PM me, I don't check this account unless I have to.

Okay

I have never used github before but I have the files I edited on github now.

What the hell are you doing?

That is not a PullRequest...

Also your change is... pointless or I don't get what you want.

A Block does not have NBT. An ItemStack has NBT data and you can access that just fine in your ItemBlock to provide different Icons based on the NBT.

This would do it so mutch easyer to make it work!

But if it doesn't work I will try other things

Why Has the Forge Development Forum Become So Empty?

I agree, and that's why I've enabled the RSS notifications for the forums on my phone. Often times it is difficult to share things on here that can be condensed into a single forum post. As for development, the discussion that happens on GitHub is not for releases but rather for the active development of the feature itself. I'm happy to discuss more things on the forums in the future, but I've been more focused on keeping my head down and getting things working. There's still a lot to do with the toolchain before I can do more things on the forums and the Forge project itself.

I need a mod to help build something similar litematica

Try Structurize or Building Gadgets — they work great on Forge 1.20.1 and are probably the closest alternatives to Litematica.

Why Has the Forge Development Forum Become So Empty?

Yeah, you’re totally right — it’s been noticeably quieter here over the past few years. Most of the modding discussion has definitely shifted to Discord servers and sometimes Reddit, since they offer faster responses and real-time collaboration.
Forums like this used to be the main hub for documentation and troubleshooting, but now people prefer quick chats or sharing snippets on GitHub and Discord. The downside is that a lot of useful info gets buried or lost over time instead of being archived like it was here.
