I created block. And I want it to be fuel in furnace.

GameRegistry.addShapelessRecipe(new ItemStack(coalblock, 1), new Object[] {Item.coal,Item.coal,Item.coal,Item.coal,Item.coal,Item.coal,Item.coal,Item.coal,Item.coal});
GameRegistry.addShapelessRecipe(new ItemStack(Item.coal, 9), new Object[] {coalblock});

}

@PreInit

}

@PostInit

}

 

This is code.

 

TileEntityFurnace.isItemFuel(new ItemStack(coalblock));

TileEntityFurnace.getItemBurnTime(new ItemStack(coalblock, 12800));

These strings aren't make effect.

 

Please help me. My knowledge in JAVA is very bad.

And sorry me for my very bad English. It isn't my native(Привет русским!)

Those functions don't do anything. They just return information. You are supposed to instead register an IFuelHandler.

As wrote ObsequiousNewt you need the own FuelHandler class.

Like:

 

package testpackage;

 

import testpackage.core;

import net.minecraft.item.ItemStack;

import cpw.mods.fml.common.IFuelHandler;

 

public class FuelHandler implements IFuelHandler

{

    @Override

    public int getBurnTime(ItemStack par1Fuel)

    {

        if (par1Fuel.itemID == YOURBLOCKUNLOCALIZEDNAME.blockID)

        {

            return BURNINGTIME;

        }

        else

        {

            return 0;

        }

    }

}

 

 

 

The required BURNINGTIME for 1 Item or Block is 200

And the YOURBLOCKUNLOCALIZEDNAME is unlocalized name of your block you want to be a fuel.

And this you need to write into your main mod class:

 

GameRegistry.registerFuelHandler(new FuelHandler());

 

This works for me.

Thanks a lot. But there is a small problem.

package platon.mods.coalblock;

import net.minecraft.item.ItemStack;
import cpw.mods.fml.common.IFuelHandler;

public class FuelHandler implements IFuelHandler
{
    @Override
    public int getBurnTime(ItemStack par1Fuel)
    {
        if (par1Fuel.itemID == coalblock.blockID)
        {
            return 12800;
        }
        else
        {
            return 0;
        }
    }
}

 

in string      if (par1Fuel.itemID == coalblock.blockID)      .blockID "cannot be resolved or is not a field". I fixed it by adding string: integer blockID with ID or constant with ID.  But why it doesnt works without these strings. Where blockID must be declared by default?

And one last question: How I can add information about author etc. (to watch in Minecraft main menu/Mods) There are only ver. info

Thanks a lot. But there is a small problem.

package platon.mods.coalblock;

    {
        if (par1Fuel.itemID == coalblock.blockID)
        {
            return 12800;
        }
        else
        {
            return 0;
        }
    }

Um, that doesn't sound right. How did you add this?

And one last question: How I can add information about author etc. (to watch in Minecraft main menu/Mods) There are only ver. info

https://github.com/MinecraftForge/FML/wiki/FML-mod-information-file

Another one for the EAQ, Draco. I think we actually should do this.

I added this in main mod file (coalblock.java)

So, where blockID must be declared?

I think you need the:

MAINCLASS.BLOCKUNLOCALIZEDNAME.blockID

MAINCLASS - mod main class or class where you have : test = new TestBlock(1, Material.rock)...

BLOCKUNLOCALIZEDNAME - unlocalizedname of your block

I changed problem string to    if (par1Fuel.itemID == coalblock.coalblock.blockID)  it is no more errors, But game crashes when i put this block into the furnace.

By The Way, Watch to my package.

}

I changed problem string to    if (par1Fuel.itemID == coalblock.coalblock.blockID)  it is no more errors, But game crashes when i put this block into the furnace.

Logs?

Post the errorlog. The block worked before without errors?

 

I think you have to replace this line/s:GameRegistry.registerBlock(coalblock);

With this: GameRegistry.registerBlock(coalblock,"coalblock");

 

I wondering this is the error, but I dont know without any logs what is the problem.

And why you have this line/s ?

@Instance("CoalBlockID")

public static coalblock instance;

It may be:

@Instance

public static coalblock instance = new coalblock();

Yes, of course. Error code

I know why it is doing this error.

Try replace this line in your FuelHandler:

if (par1Fuel.itemID == coalblock.coalblock.blockID)

With:

if (par1Fuel.blockID == coalblock.coalblock.blockID)

I hope, it will works

 

I think you have to replace this line/s:GameRegistry.registerBlock(coalblock);

With this: GameRegistry.registerBlock(coalblock,"coalblock");

 

No changes.

Did you tried what I writed before ?

 

Try replace this line in your FuelHandler:

if (par1Fuel.itemID == coalblock.coalblock.blockID)

That doesn't work.  I writed that it works when blockID is delcared. e.g. I can create integer blockID in coalblock with ID. I think when there is a string  if (par1Fuel.itemID == coalblock.coalblock.blockID)  blockID equals "null"

Hey man!

Do you have 1.5 Minecraft version and latest forge version?

Because if I try code, which I writed there it works. Try to recreate it one more time!

In main class in load function:

 

GameRegistry.registerFuelHandler(new FuelHandler());

 

The FuelHandler:

 

package mar21.omega.mar21;

 

import platon.mods.coalblock.coalblock;

import net.minecraft.item.ItemStack;

import cpw.mods.fml.common.IFuelHandler;

 

public class Mar21FuelHandler implements IFuelHandler

{

    @Override

    public int getBurnTime(ItemStack par1Fuel)

    {

        if (par1Fuel.itemID == coalblock.coalblock.blockID)

        {

            return 1600;

        }

        else

        {

            return 0;

        }

    }

}

 

 

 

and try replace this line:

Block coalblock = (new BlockCoalBlock(649)).setHardness(3.0F).setResistance(10.0F).setLightValue(0).setUnlocalizedName("coalblock");

with:

Block coalblock = new BlockCoalBlock(649).setHardness(3.0F).setResistance(10.0F).setLightValue(0).setUnlocalizedName("coalblock");

That... will have no effect whatsoever.

It's :

coalblock = (new BlockCoalBlock(649)).setHardness(3.0F).setResistance(10.0F).setLightValue(0).setUnlocalizedName("coalblock");

not

Block coalblock = (new BlockCoalBlock(649)).setHardness(3.0F).setResistance(10.0F).setLightValue(0).setUnlocalizedName("coalblock");

Your block is already declared with this code :

No any changes. Still no errors. But crashes anyway.

It's :

Huh!!! You are right. It works. And doesn't crashs. You're genius!!! I learned MC modding by one fucking Topic. Thanks a lot!!!

You're really helped me!! 

I want to ask last question: How is my english? Is it hard to understand me?

Good and No 

It is hard to understand me ?
