[1.12.1] Registering a shaped recipe crashes on world load


Recommended Posts

	public static void registerRecipes(RegistryEvent.Register<IRecipe> event) {
		Souls.logger.info("register recipes");

		ItemStack recipeOutput = new ItemStack(ModObjects.ENDERSTEEL_BARS.getItemBlock(), 16);

		GameRegistry.addShapedRecipe(new ResourceLocation(Souls.MODID, "endersteel_bars.recipe"), null, recipeOutput,
				new String[] { "EEE", "EEE" }, 'E', ModObjects.ENDERSTEEL.getItem());
	}

This code doesn't crash when it's called, but it completely freezes the game on loading a world. Here's the log:

This freeze happens regardless of whether I register the recipe with GameRegistry.addShapedRecipe orForgeRegistries.RECIPES.register(new ShapedOreRecipe) 

What am I doing wrong?

1) Use JSON not in code.

2) Your items are invalid.

3) What the hell is this:

		List<Object> args = new ArrayList<>();
		args.addAll(Arrays.asList(recipe));
		args.addAll(Arrays.asList(map));

It's a varargs, you don't need to do any of that crap...

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

Ah yea I should have simplified it for this post. The reason I was doing it like that is a mixture of old code and trying to figure out exactly what the problem is. 

 

You said my items are invalid, what's invalid about them? If I don't register this recipe the items seem to work fine, including in shapeless recipes.

Not sure, something in the depths of building the search tree is hitting your items and nulling out.

Try debugging your code... See whats null in that exception.

But again, STOP using code to register recipes.

I'm only using a simple recipe for testing, the recipes I'm actually using code for are much more complicated, things I don't expect I'll be able to do with the json format. I'll take a look when I get to converting the recipes to json, I just haven't gotten that far yet because of misc other conversion bugs.

 

I guess it's about time I use an IDE that supports debugging java...... it'll probably help me solve issues like this way easier >.> (I use VSCode for web-dev, just didn't want to spend the time configuring IDEA again--lost all my settings on a crash last time)

 

Anyway, thanks for the help. I'll keep forging ahead.

Ya, if you cant do it with json you're using the json wrong.

And that isn't hyperbole, the json can LITERALLY do everything code can.

Its just a matter of if it's intended to do that or not.

If you find a case where you cant do something let us know and we can expand the functionality, that's kinda the point of Forge.

People don't make IDEs for shits and giggles, they are really powerful tools...

Sure @LexManos, here's one. It's not recipes, its advancements, but still, it's something JSON cannot do currently (requires reflection hacking to register new ICriterionTriggers):

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

I figured out the reason this was crashing, my recipe output item was never registered. The json recipe system warned about it on parsing. I guess it's kinda pointless to add in checks for that since it's heavily encouraged to use json recipes now.

 

(not related, but grats on 10k draco!)

You should always register your items and use configs to make them craftable or not.

I didn't neglect to register the item on purpose >.> It was just a bug--I have two different superclasses for Blocks and BlockPanes and I had forgotten to register the BlockPanes on my Register<Block> event. ....When I get a chance I think I'll make an interface for these so that having separate superclasses isn't an issue I have to worry about anymore.

    • So me and a couple of friends are playing with a shitpost mod pack and one of the mods in the pack is corail tombstone and for some reason there is a problem with it, where on death to fire the player will get kicked out of the server and the tombstone will not spawn basically deleting an entire inventory, it doesn't matter what type of fire it is, whether it's from vanilla fire/lava, or from modded fire like ice&fire/lycanites and it's common enough to where everyone on the server has experienced at least once or twice and it doesn't give any crash log. a solution to this would be much appreciated thank you!
    • It is 1.12.2 - I have no idea if there is a 1.12 pack
    • Okay, but does the modpack works with 1.12 or just with 1.12.2, because I need the Forge client specifically for Minecraft 1.12, not 1.12.2
    • Version 1.19 - Forge 41.0.63 I want to create a wolf entity that I can ride, so far it seems to be working, but the problem is that when I get on the wolf, I can’t control it. I then discovered that the issue is that the server doesn’t detect that I’m riding the wolf, so I’m struggling with synchronization. However, it seems to not be working properly. As I understand it, the server receives the packet but doesn’t register it correctly. I’m a bit new to Java, and I’ll try to provide all the relevant code and prints *The comments and prints are translated by chatgpt since they were originally in Spanish* Thank you very much in advance No player is mounted, or the passenger is not a player.
