Entity Problems

[High42Score]

Hello community,

 

I recently started updating my mod from 1.2.5 (Where everyting was running fine) to 1.3.2. I managed to remove nearly all errors, but a few are left, most of them releated to entities:

 

I have a block, which has to drop an item onDestroyedbyPlayer.

Current Code:

 

public void onBlockDestroyedByPlayer(World world, int i, int j, int k, int l)

    {

        ItemStack itemstack = new ItemStack(mod_Test.SomeNewItemID, 1, 0);

          EntityItem entityitem = new EntityItem(world, i, j, k, itemstack);

   

        if (!world.isRemote)

        {

        world.spawnEntityInWorld(entityitem);

        }

    }

 

The new Item is working. If I change the Item to a feather or something like that, it works.

If I destroy the block, the game crashes with a NullPointerException:

And something strange:

I can´t use EntityRegistry.registerModEntity. The game crashes when spawning the mob (or another entity):

registerGlobalEntityID alone works fine. Really strange...

 

I hope you can help me or something like that^^

 

btw: I am using the latest forge build.
