I'm currently trying to get a custom fire block to render (I'll add in standard fire functionality later) and so far every time I try to load up my dev world, minecraft crashes.

below are the three files I'm using.

The generic mod block file

package com.wolfamaril.coloredflame.block;

 

import com.wolfamaril.coloredflame.creativetab.CreativeTabColoerdFlame;

import com.wolfamaril.coloredflame.reference.Reference;

import cpw.mods.fml.relauncher.Side;

import cpw.mods.fml.relauncher.SideOnly;

import net.minecraft.block.Block;

import net.minecraft.block.BlockFire;

import net.minecraft.block.material.Material;

import net.minecraft.client.renderer.texture.IIconRegister;

 

 

public class BlockColoredFlame extends BlockFire

{

  /* public BlockColoredFlame(Material material)

    {

        super(material);

    }*/

 

    public BlockColoredFlame()

    {

        //this(Material.fire);

        this.setCreativeTab(CreativeTabColoerdFlame.COLOREDFLAME_TAB);

    }

    @Override

    public String getUnlocalizedName()

    {

        return String.format("tile.%s%s", Reference.MOD_ID.toLowerCase() + ":", getUnwrappedUnlocalizedName(super.getUnlocalizedName()));

    }

 

    @Override

    @SideOnly(Side.CLIENT)

    public void registerBlockIcons(IIconRegister iconRegister)

    {

        blockIcon = iconRegister.registerIcon(String.format("%s", getUnwrappedUnlocalizedName(this.getUnlocalizedName())));

    }

 

    protected String getUnwrappedUnlocalizedName(String unlocalizedName)

    {

        return unlocalizedName.substring(unlocalizedName.indexOf(".") + 1);

    }

}

 

 

The Actual Fire base file

 

package com.wolfamaril.coloredflame.block;

 

import net.minecraft.world.World;

 

import java.util.Random;

 

public class BlockFireColoredBase extends BlockColoredFlame

{

    public boolean isOpaqueCube()

    {

        return false;

    }

 

    public boolean renderAsNormalBlock()

    {

        return false;

    }

 

    public int getRenderType()

    {

        return 3;

    }

 

    public int quantityDropped(Random p_149745_1_)

    {

        return 0;

    }

 

    public int tickRate(World p_149738_1_)

    {

        return 30;

    }

}

 

and one of the 16 files I'll eventually be using to make colored fries

package com.wolfamaril.coloredflame.block;

 

public class BlockFireColoredBlack extends BlockFireColoredBase {

    public BlockFireColoredBlack()

    {

        super();

        this.setBlockName("blackFire");

        this.setBlockTextureName("fireBlack");

        this.setBlockTextureName("fireBlack_Layer0");

    }

}

show me the crash report

Crash Report in the cut.

Your constructor for BlockColoredFlame never calls super.

 

As for the crash, you overrode registerBlockIcons, but you didn't override getIcon, and BlockFire's getIcon returns an IIcon from a private array, which you didn't write into.  Or allow to be initialized at all.

OK, this is probably one of the noobest questions you've ever had, but how would I go about using my custom fire textures?

(already have the textures, just was never very good at making arrays work)
