Is there a way to add new stairs and slabs to the game made of your own block like adding iron stairs or iron half slabs

maybe try extending BlockStairs and just change the texture?

That may work but when I tryes that it gave me about 10 errors.

Since i wanted to have a look in this anyway i did a bit sooner than i originally planned to, here is what i figured out:

1.Have your own Block class:

(I will use code examples from my own litle mod)

package NewOldStuff;

import net.minecraft.block.Block;
import net.minecraft.block.material.Material;

public class nosBlock extends Block {

public nosBlock (int id, int texture, Material material) {
	super(id, texture, material);
}

@Override
public String getTextureFile () {
	return nosCommonProxy.BLOCK_PNG;
}

}

 

2.Have a class that extends BlockStairs (as keepcalm already suggested):

 

package NewOldStuff;

import net.minecraft.block.Block;
import net.minecraft.block.BlockStairs;
import net.minecraft.block.material.Material;

public class nosStairs extends BlockStairs {

public nosStairs (int id, Block block, int par3) {
	super(id, block, par3);
}

@Override
public String getTextureFile () {
	return nosCommonProxy.BLOCK_PNG;
}

}

 

3.Now create a new Block with the texture you would like to use and use that Block to create some new stairs:

	public static Block strawBL = new nosBlock(3502, 2, Material.cactus)
    .setHardness(0.5F).setStepSound(Block.soundGrassFootstep)
    .setBlockName("strawBL").setCreativeTab(CreativeTabs.tabBlock);

public static Block strawRF = new nosStairs(3503, strawBL, 1)
    .setHardness(0.5F).setStepSound(Block.soundGrassFootstep)
    .setBlockName("strawBL").setCreativeTab(CreativeTabs.tabBlock);

 

4.Register your new Stairs as any other Block, but not your "helper-block", unless you want to be able to use it in-game too

		LanguageRegistry.addName(strawRF, "Straw Thatch");
	MinecraftForge.setBlockHarvestLevel(strawRF, "axe", 1);
	GameRegistry.registerBlock(strawRF);

 

5.Works:

I still have to figure out how to correct the lighting.

 

To fix the shading on stairs and slabs, add the following to their class constructor:

this.useNeighborBrightness[id] = true;
