Hi, I have this problem that minecraft crashes when i add all the reciepes needed(from the reciepe I`ve made) to make a new block. I can give this block by /give , place it, mine the block etc. But I cannot craft or smelt it. It says nullpointer on getMetadata()

Ill put all info that might be of interrest in this problem. Help is really appreciated!

Heres the initialisation of the block:

test_block = new BlockTest(Material.rock).setUnlocalizedName("test_block").setCreativeTab(TutMod.tab);

register:

GameRegistry.registerBlock(test_block, test_block.getUnlocalizedName().substring(5));

register render:

registerRender(test_block);

public static void registerRender(Block block){

Item item = Item.getItemFromBlock(block);

Minecraft.getMinecraft().getRenderItem().getItemModelMesher().register(item, 0,new ModelResourceLocation(Reference.MOD_ID + ":" + item.getUnlocalizedName().substring(5),"inventory"));

}

 

here is my reciepe:

GameRegistry.addRecipe(new ItemStack(test_block),new Object[]{"ddd","ddd","dd ",'d',Blocks.dirt}

blockState json file:

{

    "variants": {

        "normal": {"model": "tm:test_block"}

    }

}

block model json:

{

    "parent": "block/cube_all",

    "textures": {

        "all": "tm:blocks/test_block"

    }

}

block item json:

{

    "parent": "tm:block/test_block",

    "display": {

        "thirdperson": {

            "rotation": [ 10, -45, 170 ],

            "translation": [ 0, 1.5, -2.75 ],

            "scale": [ 0.375, 0.375, 0.375 ]

        }

    }

}

 

This is just a guess, but you seem to be missing a parenthesis at the end of this bit of code

GameRegistry.addRecipe(new ItemStack(test_block),new Object[]{"ddd","ddd","dd ",'d',Blocks.dirt});<-- Add this

 

Let me know if that does anything.

You've added a recipe for an

ItemStack

with a

null

Item

. You should instantiate and register your

Block

s and

Item

s in preInit and then add your recipes in init.

Well, this is my init public static void init(){

test_block = new BlockTest(Material.rock).setUnlocalizedName("test_block").setCreativeTab(TutMod.tab);

test_turret = new BlockTest(Material.rock).setUnlocalizedName("test_turret").setCreativeTab(TutMod.tab);

GameRegistry.addRecipe(new ItemStack(test_block),new Object[]{"ddd","ddd","dd ",'d',Blocks.dirt});

test_block.setHardness(2);

test_block.setHarvestLevel(Tool.class.getTypeName(), 4);

test_block_block = new BlockTest(Material.rock).setUnlocalizedName("test_block_block").setCreativeTab(TutMod.tab);

test_block_block.setHardness(3);

GameRegistry.addRecipe(new ItemStack(test_block_block),new Object[]{"bbb","bbb","bbb",'b',Blocks.dirt});

GameRegistry.addSmelting(Blocks.dirt,new ItemStack(test_block_block) , 20.0F);

 

}

so the block isnt null at the point I`m adding the reciepe

Still not figured

 

you add recipes in your main item/block class (in init package for me) where you registered your item for example:

 

public static void register(){

GameRegistry.registerItem(youritem, youritem.getUnlocalizedName().substring(5));

 

GameRegistry.addRecipe(new ItemStack(youritem), new Object[] {"SSS","SSS","SSS", 'S', Blocks.dirt});

 

}

Well it workds just fine with items, but not with blocks

put same code in your main blocks class? ._.

It is already in my main block class

It already there :

@EventHandler

public void preInit(FMLPreInitializationEvent event) {

TutorialItems.init();

TutorialItems.register();

TutorialBlocks.init();

TutorialBlocks.register();

GameRegistry.registerWorldGenerator(new TutModBlocksGeneration(),0);

}

 

------------------------------------------------------------------------------------------------------------------

 

public class TutorialBlocks{

 

public static Block test_block;

public static Block test_block_block;

public static Block test_turret;

 

public static void init(){

test_block = new BlockTest(Material.rock).setUnlocalizedName("test_block").setCreativeTab(TutMod.tab);

test_turret = new BlockTest(Material.rock).setUnlocalizedName("test_turret").setCreativeTab(TutMod.tab);

GameRegistry.addRecipe(new ItemStack(Blocks.diamond_block),new Object[]{"ddd","ddd","dd ",'d',Blocks.dirt});

test_block.setHardness(2);

test_block.setHarvestLevel(Tool.class.getTypeName(), 4);

test_block_block = new BlockTest(Material.rock).setUnlocalizedName("test_block_block").setCreativeTab(TutMod.tab);

test_block_block.setHardness(3);

 

 

}

public static void register(){

GameRegistry.registerBlock(test_block, test_block.getUnlocalizedName().substring(5));

GameRegistry.registerBlock(test_block_block, test_block_block.getUnlocalizedName().substring(5));

GameRegistry.registerBlock(test_turret, test_turret.getUnlocalizedName().substring(5));

GameRegistry.addRecipe(new ItemStack(test_block_block),new Object[]{"bbb","bbb","bbb",'b',Blocks.dirt});

GameRegistry.addSmelting(Blocks.dirt,new ItemStack(test_block_block) , 20.0F);

}

public static void registerRenders(){

registerRender(test_block);

registerRender(test_block_block);

registerRender(test_turret);

}

 

public static void registerRender(Block block){

Item item = Item.getItemFromBlock(block);

Minecraft.getMinecraft().getRenderItem().getItemModelMesher().register(item, 0,new ModelResourceLocation(Reference.MOD_ID + ":" + item.getUnlocalizedName().substring(5),"inventory"));

}

}

Well, now it just worked

I think it was that i initialized blocks and reciepes for blocks before items
