When I run my Minecraft mod, it runs fine for a few seconds, but then crashes before I get to the title screen. The console says, "AL lib: (EE) alc_cleanup: 1 device not closed".

Please read the actual error message, it clearly tells you whats wrong (especially if you then look at the code that's producing it).

Also, stop using deprecated methods.

From my best guess, it has something to do with registering items. I haven't been able to properly learn how to register an item in versions 1.8 and later. Can you please teach me? Also, if registerItem() is deprecated, what should I use instead?

register(IForgeRegistryObject)

register(IForgeRegistryObject)

What's an IForgeRegistryObject?

Almost anything is an IForgeRegistryObject Items and Blocks are the mainly used one but Enchantments and PotionEffects(something to do with potions). You need to call setRegistryName on the object first or it will not work, but for blocks you need to register the item as well as the blocks themselves or there won't be any Item for the block.

 

The interface is actually called

IForgeRegistryEntry

and the method to register it is

GameRegistry.register

.

Thanks, I could not remember the exact interface name and was unable to look it up (traveling).

For registering blocks and items I have in both item and block libraries a register fuction for when I'm registering things.

 

Here's the item version:

 

    public static void regItems(Item item){
    	GameRegistry.registerItem(item, item.getUnlocalizedName().substring(5));
    }
}

 

Here's the block version:

 

public static void regBlocks(Block block){
	GameRegistry.registerBlock(block, block.getUnlocalizedName().substring(5));
}
}

 

All in All, they're very similar.

 

EDIT: And I've just posted for no reason it seemes. I just looked at the date of the first post and BAM! from the 9.  :P

Well if someone else is having trouble with the same thing, they could get some info out of this.

I don't see the problem with the code I gave. I use it in my 1.10.2 mod and it works perfectly.

The problem is that it will be removed in the next version of minecraft and you will need to change it anyway.

Really!? I really need to get up-to-date with the next updates then!

Yes, "Really!"... That's what @Deprecated means... it's not there for show...

 

Sorry! I'm used to using C# not Java!

C# had ways to mark methods as deprecated too.

C# had ways to mark methods as deprecated too.

 

Yes, but I wrote all my code aswell. Which doesn't help when making mods.

I mean the fact that after using the method it gets a nice line through it that's supposed to hint to you, "Hey dummy! This method is deprecated!" And then you look at the Javadoc (C# had something similar too) and read it and think, "Oh, this method is deprecated and tells me what to use instead, maybe I should dip that thing."

In my code right now, my item is being registered twice. Is it better to register all the items in one class, or is it better to register each item in its own class?

I have multiple ways you could do this.

1. In the constructor of the class you can add this to an array in a class then have a method that loops through all of the values in the array and register them.

2. You could pass a string into the constructor of your items class and register them there as you said.

Almost anything is an IForgeRegistryObject Items and Blocks are the mainly used one but Enchantments and PotionEffects(something to do with potions). You need to call setRegistryName on the object first or it will not work, but for blocks you need to register the item as well as the blocks themselves or there won't be any Item for the block.

This was slightly confusing. Can you please give an example or link me to a tutorial that's up-to-date?

You can look at the link in my signature and look at my RegistryHelper class for an example on how that is handled.

Thanks. It's registered now.
