[1.8] Obtain any block texture for use in TESR rendering

[10paktimbits]

I have a storage block/container/tesr that allows the user to add any block to a single slot in the gui.

 

I need to obtain the texture of the block dropped into the slot for rendering in the TESR.

 

How can the texture be obtained in 1.8?

 

Also, is this the correct texture to assign?

 

this.renderManager.renderEngine.bindTexture(TextureMap.locationBlocksTexture);

 

Thanks.

That should be the stitched texture sheet, yes.  You'll still need to bind the texture (making sure that OGL is drawing with the right texture) and get the UV coordinates from the block's IIcon (to draw the correct portion).

Right.

 

In the tesr renderer, I have access to the ItemStack containint the block the user dropped into the gui.

 

How can I get the texture of that block in the ItemStack?

[Draco18s]

Item item = stack.getItem();
Block block = Block.getBlockFromItem(item);
block.getIcon(side, meta);

 

Note that I didn't attempt to check for null, etc.

I'm trying to do this in 1.8 not 1.7.x.

 

What is the 1.8 equivalent of what you just posted?

 

Thanks.

I'm not familiar with 1.8, unfortunately.

 

You'll have to dig around to figure out how Minecraft's renderer (RenderGlobal?) figures that out.  The whole json thing irks me, TBH.  I mean, I get why it exists, so that resource packs can alter the shapes of blocks as well as the texture, but the implementation lost something in the process.

I think this is the way to get what I am looking for...

 

Minecraft mc = Minecraft.getMinecraft();
IBlockState blockState = Block.getStateById(Block.getIdFromBlock(block));
BlockRendererDispatcher blockRendererDispatcher = mc.getBlockRendererDispatcher();
BlockModelShapes blockModelShapes = blockRendererDispatcher.getBlockModelShapes();
IFlexibleBakedModel bakedModel = (IFlexibleBakedModel)blockModelShapes.getModelForState(blockState);
TextureAtlasSprite sprite = bakedModel.getTexture();
int textureX = sprite.getOriginX();
int textureY = sprite.getOriginY();

 

...anyone know a better way?

[Draco18s]

That's likely the best you're going to get. 1.8's rendering is weird and annoying due to the multiple levels of wrappers.

That would not work in some case, like block models with multiple textures.

Why do you want to obtain texture?

I think you can just display the item. (In this case, something like ItemRenderer#render(IBakedModel) would be sufficient)

[10paktimbits]

I am making a block (#1) that allows the user to select another block (#2) who's texture will be used to render inside of block #1.

 

Item rendering won't work - I need to render many faces in different locations within block #1 - just like I was able to in 1.7.10.

 

My code above does not work - I only get a solid white color on the face I'm rendering rather than the block texture I'm trying to use.

 

And yes, I need to be able to have access to all textures in a block like wool or glass.

I stored whatever IBlockState the block is supposed to render as as a field in the block's TileEntity, then fetch it in the ISmartBlockModel:

@Override
public IBakedModel handleBlockState(IBlockState state) {
	if (state instanceof IExtendedBlockState) {
		IBlockState renderState = ((IExtendedBlockState) state).getValue(YourBlock.RENDER_STATE_PROPERTY); // obviously you'll have to change this
		if (renderState != null) {
			IBakedModel renderModel = mc.getBlockRendererDispatcher().getBlockModelShapes().getModelForState(renderState);
			if (renderModel instanceof ISmartBlockModel) {
				renderModel = ((ISmartBlockModel) renderModel).handleBlockState(renderState);
			}
			return renderModel;
		}
	}
	return defaultModel;
}

It works for the 99% of cases, but obviously there will always be some that won't work. Personally, I just use it for solid, cube-shaped blocks.
