Update Regarding LTS System: Please read The Big Forge Update Earlier this year, 1.13 was announced and the snapshots started coming out, the update was relatively small, but enough to be a hurdle for mod developers. This combined with 1.12 stabilizing, and a few fundamental Java changes that broke modding in general, made the Forge team decide to use this opportunity and work on cleaning the years of technical debt that Forge had accrued. During this time, it was discovered that a lot of things needed updating. In fact, well, everything did. And so, it was done, a

Minecraft 1.12: The newest version of Minecraft has been released. Forge has been updated to support this new version. However due to the way Mojang implemented the Recipe changes there are a lot of under the hood changes that we need to do. Most notably re-writing on of the largest/most intricate systems of Forge, The Registry system. This will take some time, so do not expect a recommended release quickly. However if you are a modder you can start using the current versions to build against. Some API's may change in the early days of Forge so be sure to be ready for that. I'm sorry, I u

What is this? This is a collection of common issues and recommendations for the Modder Support subforum. Instead of repeating these things over and over again, a link to this thread can be used instead. This post will be updated as needed. Suggestions either via PM to me or in a separate thread to keep this topic clean.

As anyone who's started porting to 1.14.2 is probably aware by now, container and GUI creation has changed... quite a bit. To summarise what I've gathered so far: Containers (more accurately: container types) are now registry objects and must be registered in a RegistryEvent.Register<ContainerType<?>> event handler. Container objects themselves must provide a constructor of the form MyContainer(int windowId, PlayerInventory inv, PacketBuffer extraData). This will be used to instantiate the client-side container. Your container's constructor must call the super C

Forge for 1.16.1 The first Forge build for 1.16.1 is now live thanks to the hard work of: covers, illy, jd, garrett, giga, and the rest of the forge crew. With their help we were also able to release the updates to MCPConfig for 1.16 and 1.16.1 the same day that vanilla did. The Nether Update has brought a lot of changes to many systems, and as with any update there are likely to be bugs. We are still evaluating and working on some of the systems like dimensions and trees to come up with the best system to allow for modders to integrate with vanilla’s new dimension system. We are also expect

Forge Version: 1.14.4-28.1.0 Minecraft Version: 1.14.4 Downloads: Changelog (Direct) Installer (Direct) MDK (Direct) Intro: Whelp, the time has finally come, we are ready to do our first Recommended Build for 1.14.4! I want to thank everyone who has helped work on this and get it ready to go. This has been a long road, and I admit it has been a lot longer than I wanted it to be. Unfortunately, some things went wrong, some aspects took way longer than they should have. But we move forward. This is one of the biggest updates to Forge that we have ever done. Everyth

Problematic Code Please use the registry events to register your blocks, items and other registry entries. Use ModelLoader.setCustomModelResourceLocation in ModelRegistryEvent to register your item models. Do not use the ItemModelMesher. Do not use methods that are deprecated in Forge or vanilla Minecraft. Usually there will be an explanatory method next to the method explaining what to use instead. There is an exception for methods in the Block class, these may be overridden. Instead of calling them, use the one in IBlockState resp. it's supertypes.

Code-Style The concept of a "common proxy" does not make sense. The whole point of @SidedProxy is to abstract over client specific and server specific behavior, the opposite of "common". Common code should go in your main mod class. Use @Override when you intend to override methods. This helps tremendously when updating your code for new versions of Minecraft, but in general is good practice. Read this Stack Overflow answer for an explanation. Using an interface (usually called IHasModel) on your Item and/or Block classes to denote that they are capable of registering a model

No. Stop. writeToNbt and readFromNbt are for saving to disk. Server-side. If you want to sync stuff to the client (assuming you want to use the vanilla mechanic, which uses NBT), you need to override a couple of methods (warning, this is a giant mess): getUpdateTag - Returns the data that should be sent to the client on initial chunk load (i.e. when it gets into render distance, etc.). Call super here and put whatever data you need to have available on the client in the NBTTagCompound returned from super. Then return it. handleUpdateTag - Called on the client with whatever tag was

General issues Do not use the "export" or "create jar file" functionalities of your IDE or other means to create your final mod file. You must use the Gradle build task. See the documentation for more info. When creating a Git repository for your mod, the repository root should be where your build.gradle file is. The MDK ships with a default .gitignore file so that only the necessary files will be added to version control.

Forge Version: 31.1.0 Minecraft Version: 1.15.2 Downloads: Changelog: (Direct) Installer: (AdFocus) (Direct) MDK: (AdFocus) (Direct) Intro: This is the first recommended build for 1.15.x! This would of been out a few weeks ago, but Mojang decided to release 1.15.2, so we figured it'd be best to hold off until that version stabilized. As you may have read, we dropped 1.12 support a few weeks ago and now concentrate on 1.14.4 and 1.15.2 until 1.16 drops. 1.15.x brought many changes to the rendering engine and incorporated some parts of the new rendering engine k

This solved the problem for me First register your entity with custom client factory like this .setCustomClientFactory((spawnEntity, world) -> new ExempleEntity(world)) And then use NetworkHooks#getEntitySpawningPacket to get Entity Spawning Packet @Override public IPacket<?> createSpawnPacket() { return NetworkHooks.getEntitySpawningPacket(this); } that's it ?

Don't tell ppl "do your research before posting here" as the README.txt file that comes with the MDK of Forge 1.13.2 25.0.9 and 25.0.10 says to use setupDecomWorkspace its obvious that the README.txt file was not updated but you don't have to be a dick.

The problem with most alternative mod loaders, is that they are created out of spite with "Fuck Forge" as their motivation. But then they use our tools, our data, and our work to make their system. That's the thing that pisses me off about things like Rift. I have not looked at Fabric so i can't comment on what they are doing, or if they are doing it correctly/legally. However, I would also advise against using any loader that "gives the hooks to the users", by "exposing" mixins and encouraging the average user to use it. Because that flat out won't work. The

You can view the entirety of Forge 1.13 here: https://github.com/MinecraftForge/MinecraftForge/tree/1.13-pre?files=1 I think that Forge 1.13 is 80-90% done based on: - Forge Gradle 3 is finished (this was the part that unexpectedly took the longest) - I believe the MCP mappings are pretty much done for 1.13 - From what I’ve seen on the comits they’ve managed to get Forge 1.13 (without all the patches) to compile and run (I’m traveling right now so I can’t test it and confirm it myself) - I judge that the rewriting of the mod loading system is probably more than

First off, you can't even spell my name right, secondly for those who see this, this is the thread he got a warning for, specifically the post where he called us all assholes http://www.minecraftforge.net/forum/topic/65936-forge-server-error/ As you can see, nobody cussed at him. As for us being assholes, because we are blunt and have rules, and refuse to support older versions does NOT make us assholes. The analogy I like to take is you going to Microsoft, and asking for support with Windows 95. They will tell you to either sod off or pay them a ABSURD amount of money.

Locked. JRed you are consistently coming around asking for help with your fucking coremod that I'm fairly sure every member of staff has asked you to stop using, yet you insist on hacking the shit out of everything because you think you know better yet you refuse to prove that your way is better by contributing to Forge directly. I will say this again, if you are having trouble with making a coremod maybe you shouldn't be hacking the shit out of other people's code.

@DifferentiationIt is good that you understand the rules of the forum, and also nice that you're actively particpating and interested in modding. However, the only people that should enforce the rules are official moderators. It is even okay to suggest someone should spend time learning more Java, but some of your posts are literally telling people to "go away" or "we're not going to support that". No one except official moderators should ever tell someone to go away or try to draw a line over support. Now I often see people who post and I can tell that they're likely

Hey Lex, all the words I have stated against you were a result of a long time of bearing a grudge against you. Now, I would like to make things right. When IItemRenderer was originally deprecated, I searched up real quick to see if anyone else was having an issue with the code not being called. I found a thread about it, with you replying to them with something along the lines of it won't be added back since copy-pasters constantly screw it up. At that moment, a grudge formed against you, from my eyes it looked like this: "Because you couldn't tolerate copy-pasters,

I got into minecraft modding recently and was surprised by how hard it is to find useful up-to-date information. Because of that, I decided to document my learning journey and write a book about Minecraft modding for beginners. It applies to Minecraft 1.16.1 and the latest version of forge. Keep in mind it is still a work in progress. More chapters will be added in the coming days. Suggestions and questions also are welcomed. Link: https://thebookofmodding.ml/

In honor of this thread, Im going to quickly summarise what I have gathered about creating villagers professions in 1.14.4 (forge 28.1.109) as there is not really that much information about that available right now. If anyone sees me doing something wrong or saying bs, just let me know and I will fix it. Specifically the reflection fix I mention below. EDIT: Make sure you check the first couple replies as well. Source for all of this can be found specifically in this commit: https://github.com/CAS-ual-TY/GunCus/commit/817848784868f4e8362d4270be6f8fc19863dc42 Tho I have

One way is to use a method that always returns null but suppresses IDEA's warnings, like this: method, usage The newer way is to use the DeferredRegister system that was introduced relatively recently. I've started updating to this, but it doesn't look like I've pushed any of my changes to GitHub.

As there have been few attempts to create this functionality (that I can find) I decided that I'd have to do this myself. And seeing as it boodly doesn't exist anywhere, I thought I'd share. It does not extend GuiTextField, though it probably could, but it was easier to just take everything that was GuiTextField and make a new class and just make changes as needed, particularly as a lot of GuiTextField's fields were private and thus not visible to a subclass (using getters and setters was frustrating, as many setters either didn't exist or had annoying side effects, such as ignorin

I have no sympathy for you players who use Netease, their entire business model is bad and abuses the hard work that we here at Forge, and other modders do. If they want to start complaining that I don't produce Forge fast enough, then they can start helping out. But no they just sit back, toss DRM onto things, and just rake it in. It'll be done when it's done.

*shudder* This is a security hole the size of texas. "Hey server, redstone now has 1000 subtypes, they are all diamonds!" - "Sure! I'll generate diamonds everywhere!"

Seriously, Use the event not the static registries. Timing of registration is important. So stop doing it in random places. I was tempted to name the event 'RegisterYourStuffHereAndStopBreakingEverythingElseSeriouslyStopRegisteringYourCrapInRandomPlacesItBreaksThingsAndHoldsUsBackFromBeingAbleToDoCoolThingsThatWeveBeenWantingToDoForFourYearsNow' but I decided against that as it was a bit long

No

Super duuuuper necro post, but for anyone who finds themselves here after trying the srgExtra line, it's been changed in newer versions of gradle (2.2-SNAPSHOT I know, but maybe even earlier). Now instead of doing: minecraft { ... srgExtra "PK: ..." } You have to do: reobf { jar { extraLine "PK: ..." } } Relevant XKCD: https://xkcd.com/979/

Not sure if you have a question or anything. All I can say is: kudos to you for actually doing research and not blindly copying outdated terrible tutorials.

Finally. Give me a couple hours and I’ll have pushed my changes to ExampleMod and my tutorials that make all registration use DeferredRegisty.

You need to set the render layer using RenderTypeLookup#setRenderLayer within your FMLClientSetupEvent to make blocks transparent. It takes in two parameters: the block and the RenderType. The RenderTypes are as follows: Solid - field_228615_R_ Cutout Mipped - field_228616_S_ Cutout - field_228617_T_ Translucent - field_228618_U_ Translucent (No Crumbling) - field_228619_V_ Leash - field_228620_W_ Water Mask - field_228621_X_ Glint - field_228622_Y_ Entity Glint - field_228623_Z_ Lightning - field_228624_aa_

I know this topic is a bit old, but I just had the same issue and a Google search points here. If your packet is working correctly, and its just the warning in the log, you've likely made the same mistake as me. Inside the "messageConsumer" you provided when registering your packet, you need to set the packet handled flag to true. "context.get().setPacketHandled(true);" If it isn't set to true, NetworkHooks.onCustomPayload will return false, and ClientPlayNetHandler.handleCustomPayload will post the warning

Some recent version seems to have changed the default way IntelliJ compiles Gradle project. It used to be that it still used the IntelliJ build system, which puts resources and classes in one folder. Now "Delegate to gradle" seems to be the default, and gradle puts resources and classes in two separate folders. Make sure to set IntelliJ to not delegate to Gradle (https://www.jetbrains.com/help/idea/work-with-gradle-projects.html#delegate_build_actions).

I want to say thank you to everyone here who helps with modder support. Just having you around is really encouraging, so I always know there's someone to turn to if I get myself stuck. Three times now I've solved a problem I thought I couldn't fix on my own while writing a post to ask for help, and without y'all I'd probably just have given up. So, thank you for helping, even if you didn't know you were

No, MCP is the core and it will continue to be the core. I create MCP and thus I can trust in it's stability and availability. If modders want to make a translation tool between the two so that Fabric can load on SRG names. Then go for it. I have spoken many times about how a system should be designed. But the people who have said they wanted to help haven't followed through. Anyways, getting tired of answering this. Forge will never use Fabric. Fabric's core design of "screw it everyone's a coremod!" is NOT feasible for a large compatible modding ecosystem. Forge's major re

I'm sure you'll figure it out!

This is typical software engineering jargon for "I wouldn't do it that way." In this case, if the code works, it works. If you're going into professional programming, then maybe you should take the time to learn how to efficiently write code, but for someone who's learning how to mod Minecraft, it really doesn't matter. As time goes on, you'll eventually learn what practices to use over others. The important thing is that most of this forum will not help you out well unless you come already with code. The people here, and in many other places, do not like to just "hand out code" an

@LenManos Your staff / mods / whoever works with you was complaining about my mod code and cussing at me as well, and even other people i know said the forge forms are assholes to everyone and idc if i get baned. because you cant speak to someone like that saying you know everything. & you all so stop saying well we dont support this version any more youtubers still play with 1.7.10 & above so you really need to think twice

It took me a single google search to find that Computercraft is now opensource on GitHub and has a 1.12.2 alpha build on CurseForge...

As Draco18s is pointing out, you need to fully understand how Minecraft handles blocks. What you just said is closer to what you need to do, but we want to make sure you understand why. Basically, from a "normal" object-oriented sense you would have a Block class and you would create an instance of it every time you had a block placed in the world. Logically this is good, but it has a bad consequence for performance -- the number of instances gets very large very fast. In just one chunk there is 65k possible positions to place a block so a world of just 20 chunks is going to have

williewillus is maintaining a primer on the 1.13 changes here: https://gist.github.com/williewillus/353c872bcf1a6ace9921189f6100d09a It'll be significant work for modders but I'd say considerably easier than 1.7 -> 1.8 was.

In my case 'preview_OptiFine_1.12.2_HD_U_C8_pre' prior to 12-18-2017 was causing chests not to open. I DL'd the 12-18-2017 version that is compatible with forge 2577 and the chests open as before.

Jesus. This argument is pointless. What does it matter what they want to do? If you don't want to help someone, just ignore them. End of story. If other people decide not to help them based on reasons such as not knowing Java (and you really should learn basic Java in order to mod) then that's fine too. This argument is just cluttering up the forum with nonsense. I don't have anything else to say, but there's already an answer in this thread on how to track clicks per second, assuming that the MouseInputEvent exists on 1.8.9.

We've done a few bug fixes, performance improvements, etc. We're still working on flushing out Mojang's JSON data system. But this is being held up by modder's not wanting to say what they need. So my hopes is that people will start testing out the changes and working with us

I'm brand new to modding and a noob programmer. I learned the old way to register blocks and items using GameRegistry.register() then I found out there is actually a new, better way to register blocks, items, and even models. The new way is to use RegistryEvents and I'm a sucker for new and better things so I tried to figure out how it works. My goal with this post is to see if anything I did can be done better and whether or not this is correct. Just because it works doesn't mean it's correct. I want to have a solid base before I build on it too much. Here is what I came up with: Registr

I don't speak for the whole community but since I am a leader of Sponge, I'll throw my 2 cents in by first saying that yes, SpongeForge will be adjusted to comply. We find these changes to be a good-faith effort to make some wholesome changes to the ecosystem as an attempt at dealing with the elephant in the room: coremods. SpongeForge falls under a coremod which will not function at all without its core changes but, as Lex has mentioned above, we can simply make the core portion not function at all should the whole thing not be here and throw up a descriptive error to say why. Expect to see s

The mesher is a tricky method called during init. Used by vanilla but now discouraged for mods, it's tricky because certain things need to be called in a certain order (and the client side-only proxy is involved, which separates some of those statements in code space). I believe that Forge created the custom location method because it's much less fragile. Note that it's called during preInit, not init. The threads discouraging mesher use run like a rash across this forum going back almost 2 years. Any modder facing any rendering problems should have come across them wh
