[Solved] Block rendered as Item, crash when placed [1.7.2]

[TeNNoX]

I updated my Mod from 1.6.4, works fine in eclipse so I wanted to test it in a real Minecraft copy.

 

When I try to open the creativeTab with the blocks (I only have blocks) Minecraft chrashes:

 

java.lang.NullPointerException: Rendering item

When I spawn the item with

/give xTeNNoXx tennox_assemblymod:normal

it is rendered like an item:

 

 

And when I try to place it, this error comes up:

Hi

 

My Forge 1.7.2 version is a lot less obfuscated than yours so I can't see the functions causing the problem.

 

My guess is that your Item (ItemBlock) hasn't been registered properly.  I haven't done that in 1.7.2 yet so I'm stuck there.

I think you got something wrong. The crashed occur in the real Minecraft, completely obfuscated and shit. The decompiled one in Eclipse is running perfectly fine.

 

I could recreate the second error like this:

 

TestMod:

@Mod(modid = "tennox_test", version = "0.1")
public class Test {

Block test;

@EventHandler
public void init(FMLInitializationEvent event) {
	test = new BlockTest(Material.rock).setBlockName("tennox_test");
	GameRegistry.registerBlock(test, "tennox_test");
}
}

BlockTest:

class BlockChameleon extends Block {
protected BlockChameleon(Material material) {
	super(material);
}
}

What am I missing? some block/item registering in 1.7?

[coolboy4531]

Do all your registering stuff in preInit (FMLPreInitializationEvent)

[sequituri]

According to your crashlog, Item.getIdFromItem(this.field_151002_e) is returning with a -1 for the block ID for that ITEM. So, yeah your item in not registered with a block properly.

Do all your registering stuff in preInit (FMLPreInitializationEvent)

 

That's the solution. Thanks you very much!
