Creating custom walls with metadata blocks


ProfitOrange

Recommended Posts

Currently I have my WallBlock class set up so I can create walls by simply creating a constructor. When I tried creating them using my metadata colored cobblestone, I ran into a problem since Minecrafts BlockWall only uses Block, and doesn't have an integer like Minecrafts BlockStairs class does. I have had quite a bit of troubles with this, any help on the matter would be greatly appreciated.

Hi

 

Show your code?

 

I suspect what you're trying to do won't be possible in the way you think, because BlockWall already uses metadata for something else.  But there's nothing to stop you extending BlockWall with your own Block and overriding the method which returns the texture for rendering getIcon() and a couple of the others as necessary eg getSubBlocks()

Here is the WallBlock class:

package net.minecraft.block;

import cpw.mods.fml.relauncher.Side;
import cpw.mods.fml.relauncher.SideOnly;

import java.util.List;

import com.ProfitOrange.moshiz.MoShizMain;

import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
import net.minecraft.client.renderer.texture.IIconRegister;
import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.init.Blocks;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.util.AxisAlignedBB;
import net.minecraft.util.IIcon;
import net.minecraft.world.IBlockAccess;
import net.minecraft.world.World;

public class WallBlock extends BlockWall
{
    private Block icon;
public WallBlock(Block block)
    {
        super(block);
        this.setHardness(block.blockHardness);
        this.setResistance(block.blockResistance / 3.0F);
        this.setStepSound(block.stepSound);
        this.setCreativeTab(MoShizMain.tabDecor);
        this.icon = block;
    }
    
    @SideOnly(Side.CLIENT)
    public IIcon getIcon(int side, int meta)
    {
    	return icon.getBlockTextureFromSide(side);
    }
    
    @SideOnly(Side.CLIENT)
    public void getSubBlocks(Item item, CreativeTabs tab, List list)
    {
    	list.add(new ItemStack(item, 1, 0));
    }

    @SideOnly(Side.CLIENT)
    public void registerBlockIcons(IIconRegister icon) {}
    
    @Override
public boolean canPlaceTorchOnTop(World world, int x, int y, int z) {
	return true;
}
}

 

Here is the constructor:

public static Block ColoredCobblestoneWall = new WallBlock(coloredcobblestone).setBlockName("coloredcobblestonewall");

 

I just wanted to be able to do something like this:

public static Block ColoredCobblestoneWall = new WallBlock(coloredcobblestone, 1).setBlockName("coloredcobblestonewall");

 

The 1 after the block being the metadata value for the colored cobblestone which would bring red, thus making a red cobblestone wall.

 

I was able to get the Icons to show the correct cobblestone color, but when I placed it, it showed a black cobblestone wall, being 0 on the metadata

Yes, because you are throwing away the metadata information in this call

 

    public IIcon getIcon(int side, int meta)

    {

    return icon.getBlockTextureFromSide(side);

    }

 

use icon.getIcon(int side, int meta) instead

I removed my old code in there. What I'm trying to ask, is how would I be able to call the class like this:

public static Block BlackCobbleWall = new WallBlock(coloredcobble, 0).setBlockName("blackcobblewall");
public static Block RedCobbleWall = new WallBlock(coloredcobble, 1).setBlockName("redcobblewall");
public static Block GreenCobbleWall = new WallBlock(coloredcobble, 2).setBlockName("greencobblewall");

And so on through the 16 colored blocks, I'm not trying to make metadata walls, I am trying to use the metadata colored cobble info to create each one of the walls, but the way they are set up by default, they don't have the ability to call metadata blocks

Hi

 

The problem is - what you are trying to do is create a metadata wall, even though you don't think you are. 

 

Coloured blocks (eg wool) store their colour using metadata.  So if you want your wall to be made of blocks of different colours, it needs to be a metadata wall.

 

This link might help you understand it better - see the Blocks topics.

http://greyminecraftcoder.blogspot.com.au/p/list-of-topics.html

 

It is trivial to add a parameter to your constructor for the colour

public WallBlock(Block block, int i_metadata)

but it's not going to help you any because the metadata is separate from the block, and you will wind up creating 16 different blocks, instead of 1 block with 16 metadata values.  In order to place a block with a particular metadata, you need to set up the Item that is used to place the block - ItemBlock- that is what tattyseal meant.  For example see ItemCloth, which is used to place wool blocks.  Wuppy29 has some very useful tutorials for that.

 

Once the metadata is correct, override the getIcon in the way I suggested to make it return the correct colour when drawing the wall.

But Thanks everyone by advance to help me with this.
    • These forums are for Minecraft Forge, not Fabric. You would probably be better served posting this question wherever fabric support is given, most likely their discord server.
    • Add the new latest.log (logs-folder) with sites like https://mclo.gs/ and paste the link to it here
    • Update: I tried to reproduce the bug and found out that if I place a flare on a block and then dismantle it with the pickarang (Quark), the flare gets no NBT Tag after getting assigned an empty one through the offhand.
