Hi there,

 

I am making a minecraft mod for 1.8.9 and I'm getting these two wierd errors when I start up the game.

 

Error 1 happens on start up:

Error 2 happens when i load up the world:

Also one quick question about crops:

 

How can I make my crop plant not show up in the give command - just like wheat does it?

Are you referencing any classes in the

This is normal in the development environment. Forge forces the profile properties to filled when the integrated server starts, but there aren't any properties to fill because you're not using a real account. When a player's skin/cape texture is first requested, Minecraft sees that the profile properties are still empty and tries to have them filled; but Yggdrasil rejects the request because the previous request was too recent.

If you don't want a 

Block

to exist in 

Item

form, simply don't register an 

ItemBlock

for it.

 

In 1.8.9, call an overload of 

GameRegistry.registerBlock

with a 

Class<? extends ItemBlock>

argument and pass 

null

as that argument.

 

In 1.9+, 

Block

and 

Item

registration are separated; so simply don't create or register the 

ItemBlock

.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

Is this right 

GameRegistry.registerBlock(candyPlant, null);

 

because it is telling me that:

The method registerBlock(Block, String) is ambiguous for the type GameRegistry

Then I'm not sure why the 

Native

class is being loaded.

This is one of the rare occasions where you need to cast 

null

to the appropriate type (

Class<? extends ItemBlock>

) to avoid ambiguity.

 

Without the cast, that call matches both the 

(Block, String)

and 

(Block, Class<? extends ItemBlock>)

overloads. The cast tells the compiler which one you're trying to call.

So what would the code be?

 

I'm not going to give you the code, even for something this simple.

 

You need to cast the 

null

argument to 

Class<? extends ItemBlock>

. Do you know how to cast?

I don't really know how to null cast.

 

You need to have a solid understanding of Java before you can make a mod.

 

You cast 

null

just like you cast any other value. This tutorial explains inheritance and casting.

Or you can declare a local variable of the needed type and initialize it to null before passing it as the argument to the call.

The debugger is a powerful and necessary tool in any IDE, so learn how to use it. You'll be able to tell us more and get better help here if you investigate your runtime problems in the debugger before posting.

Totally unnecessary and just a way around the fact he doesn't know Java.

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

 

1.12 -> 1.13 primer by williewillus.

 

1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.

Yup, especially when Eclipse might even offer to write the cast for him as a "quick fix" when he hovers on the ambiguous null.

Choonster do you know what JNA is and what it does ?

no ? https://github.com/java-native-access/jna/blob/master/www/FunctionalDescription.md

forge needs to hide that error or edit com/sun/jna/Native.main to use FMLCommonHandler.exitJava using asm (line 1495 in Native)

I was vaguely aware of what it was, but I didn't see any direct references to it in the Minecraft/Forge code so I wasn't sure why it was being loaded. Now that I look a bit closer, 

OpenGlHelper

references it through the OSHI 

SystemInfo

class.

 

1.10.2 doesn't log this error because 

TerminalTransformer.ExitVisitor

(the class responsible for logging it) excludes the 

com.sun.jna

package, but this wasn't the case in 1.8.9. The exclusion was added by this commit in 1.9.

      Camouflaging Mods: Rename & Reskin

      Camouflaging Mods: Rename & Reskin

      By Serhii · Posted

      Title: Why Is It So Hard to Rename and Restructure Mods Like Xray or AntiXray? 🤔 Post text: Hey everyone! I’ve been digging into Minecraft modding for a while and have one big question that I can’t figure out on my own. Maybe someone with more experience could help or give me some advice. Here’s the issue: When I take a “normal” Minecraft mod — for example, one that just adds some blocks or new items — I can easily change its structure, package names, or even rebrand it entirely. It’s straightforward. But as soon as I try this with cheat-type mods like XrayMod or AntiXray, everything falls apart. Even if I just rename the classes, refactor the packages, or hide its identity somehow, the mod either breaks or stops working properly. XrayMod in particular is proving to be a nightmare to modify without losing its core function. So my question is — why is this so much harder with cheat mods like Xray? Is there something fundamentally different about how they’re coded, loaded, or protected that prevents simple renaming or restructuring? And if so, how can I actually learn to understand someone else’s cheat mod enough to safely refactor it without breaking the core features? I’ve already been spending over two months trying to figure this out and haven’t gotten anywhere. It feels like there must be some trick or knowledge I’m missing. Would really appreciate any thoughts, tips, or references — maybe there are guides or techniques for understanding cheat-mod internals? Or if you’ve successfully “disguised” a cheat mod like Xray before, I’d love to hear how you did it. Thanks in advance for any help or discussion. ✌️

      Where did you get the schematic? Source/Link? And do use an own modpack or a pre-configured from curseforge? If yes, which one On a later time, I can make some tests on my own - but I need the schematic and the modpack name
