[SOLVED][1.7.10] Multipass rendered ItemBlock for Block with damage values

[MrCaracal]

SOLUTION: I have discovered the source of my issue.

 

After much investigation I have discovered that Vanilla's ItemBlock renderer does not care at all about any of the getIcon method family, and instead is based entirely on the associated Block's rendering. A custom renderer is required for what I am trying to accomplish.

 

Hello all!

 

I'm having a bit of trouble with a custom ItemBlock implementation. I have a multi pass rendered Block that has multiple subtypes using metadata. The first pass renders vanilla's stone brick texture, and the second pass renders a texture on top of it based on my Block's metadata. The block implementation is working as expected, but I cannot seem to get the ItemBlock's rendering to behave.

 

I have registered the custom ItemBlock in the GameRegistry alongside its Block counterpart as per the norm; The ItemBlock code is as follows:

 

public class ItemBlockTest extends ItemBlock {
public ItemBlockTest(Block passedBlock) {
	super(passedBlock);
	this.setHasSubtypes(true);
}

@Override
public int getMetadata(int metadata) {
	return metadata;
}

@Override
@SideOnly(Side.CLIENT)
public boolean requiresMultipleRenderPasses()
{
	return true;
}

@Override
@SideOnly(Side.CLIENT)
public int getRenderPasses(int metadata) {
	return 2;
}

// DEBUG!
@Override
public IIcon getIconFromDamage(int passedMetadata) {
	return Blocks.dirt.getBlockTextureFromSide(passedMetadata);
}
}

 

I have the ItemBlock's getIconFromDamage method returning Dirt's texture as a debugging measure, but this is not the case in game. The ItemBlock is instead only rendering the texture from the parent Block's second render pass, no matter what I put in the getIconFromDamage method. I know the method is being called, I had previously put a System.out.println in there; the return value just doesn't seem to be used.

 

My hunch is that the getIconFromDamage method is used for ItemBlocks that have a sprite texture and don't render as a cube, but then why wouldn't the inventory render simply show the dirt texture as a flat plane? My other hunch is that I might need a special rendering handler to accomplish what I want here: An ItemBlock that has the texture of stone bricks, with another texture overlaid based on the ItemBlock's metadata.

 

This is probably just a major derp on my part, could anybody shed some light here?

you need to use

getIcon(ItemStack stack, int pass)

and on pass 0, return the stone brick icon, on pass 1 your own texture based on the damage the ItemStack has.

There isn't a method in the ItemBlock superclass (nor in net.minecraft.Block) that matches that method signature, which was where I was looking.

 

A similar method exists in net.minecraft.Item though, as getIconFromDamageForRenderPass, but this method also does not affect the ItemBlock's rendering to any degree, no matter what I put as a return value there.

 

There are no getIcon methods that accept an ItemStack as a parameter. Ignore this, I missed it, my apologies. But the method in net.minecraft.item still does not change the ItemBlock's rendering. So far I have tried:

 

@Override
@SideOnly(Side.CLIENT)
public IIcon getIconFromDamage(int passedMetadata) {
return Blocks.dirt.getBlockTextureFromSide(0);
}

@Override
@SideOnly(Side.CLIENT)
public IIcon getIcon(ItemStack stack, int renderPass, EntityPlayer player, ItemStack usingItem, int useRemaining)
{
return Blocks.dirt.getBlockTextureFromSide(0);
}

@Override
@SideOnly(Side.CLIENT)
public IIcon getIconFromDamageForRenderPass(int passedMetadata, int passedRenderPass)
{
return Blocks.dirt.getBlockTextureFromSide(0);
}

 

And none of the three seem to alter my ItemBlock's inventory render at all.
