I am a professional game developer, but new to minecraft modding. I'm trying to help my kids make some ideas of theirs come to reality.

I was very glad to find this repository with great examples on how to get started on modding. But unfortunately none of the examples seem to fit with the kinds of ideas that we have, so I was hoping for a bit of advice on where to get started. We want to make some kind of a minigame, so what I am looking for is a way to add on my own "update loop" where our minigame can contain its own logic. Most of the samples here seem to revolve around creating new types of entities/blocks/recipes for the game which have a specific pattern to them, but it is not clear to me what the correct pattern is for adding in general-purpose code that runs all of the time in the background.

Here are some of the kinds of things I was thinking we would want the mod to be able to do:

• Allow several players to connect and join a minigame
• Present messages on each users screen so they know the state of the minigame (e.g. whether they have joined, what their current score is, etc.)
• Being able to teleport players to a new location and programmatically create some kind of arena
• Trading -- some way to alter the contents of players inventory

We are hoping to make this run on a server where several clients can connect and I don't think we actually need to create new block types etc, so possibly the mod we want to make will be server-only. (We play on hypixel, and the minigames on there don't seem to require a client side mod, they all work just by connecting to their server). I have heard of Bukkit, which seems like it is an alternative way to create server-only mods, but Forge seems like it is more flexible and i get the impression it is more recent/modern, so it would be the way to go even if we were only doing something server side.

Are there any samples you can point me to of how to create a mod/server like in my examples above? Are there are samples like that in this repo that I missed? Or other resources elsewhere?

I have already looked at the forge documentation, but it seems a bit slim and I couldn't find any direct answers there for my questions. I have also done a lot of googling and reading random forums populated by 12 year olds that banter back and forth without arriving at helpful conclusions.

Apologies if this is not the right forum for this question, I just thought I would ask since you have excellent tutorials and you seem to know what is going on.

is it for forge 1.8.9???

Hi,
First off, thank you for your great examples, learned a lot of it.
A little remark on your 1.11 branch. You're explaining the use of itemStack.func_190926_b() (for example) and that it will change in the future. It already is changed. You only need to update your mappings in the build.gradle file to something more recent. In the latest mappings all itemStack changes are properly named to increase, decrease, ItemStack.EMPTY and so on.

It could save everyone some time to read, write and understand the code.

Seems like MBE05 isn't working properly in Forge 2759 (and I assume later versions too).

At first I thought I was going mad and doing something wrong, after a day or so of debugging I eventually cloned MBE and had the exact same issue on there too.

As a sanity check I also installed Forge 2491, which this guide was made with - it all works absolutely fine in there. Looking through the Forge changelog this looks like a likely culprit, but I'll test further tomorrow:

Build 1.12.2-14.23.3.2695:
	bs2609:
		Change composite models to fetch quads from submodels using full context
		(#4809)

Hopefully you can get it updated, but someone could at least tell me what needs to be changed it'd be very useful!

Thanks

If you look carefully, you will find that the diamond block on the chess board is actually darker than what it is supposed to be. I use some of the code in that example, for block rendering is completely fine, but when it comes to item rendering, the model looks too dark. After read though the source code of Minecraft and Forge, I realize that the seventh int returned by vertexToInts() should not always be zero. That int represents an normal vector, but in packed form: ?? ZZ YY XX, it is used by OpenGL to calculate lighting.
See calculatePackedNormal() in my code for some idea about how to calc that int value:

You just need to pass coordinate of all four vertexes to the function, be careful, don`t change the order of vertexes, otherwise the result is unpredictable!

The project's goal implies public domain, but I don't see a license.

I used the Item Inventory code from your tutorial as a base for Inventory Pets Chest and Feed Bag pets, but then ran into a nasty and unsolved issue:
MinecraftForge/MinecraftForge#4594

Basically, using any inventory item with similar functionality when on a server in creative mode clears the contents of the itemstack inventory. I would remove this example since it has caused significant frustration from players, and does not look like will be solved anytime soon by Minecraft or Forge.

Since you've written this tutorial, all of the above mods, including Botania, have rewritten their code completely as a result.

I am currently attempting to add a custom modeled block into the game, but I came across an issue. Apparently, you cannot add in blocks larger than the 1x1x1 format without it being some sort of multiblock like doors and grass.

Basically just another model example, but for "large blocks" if you will with all of the voxel shapes and... things.

This is a really clean way to change the camera based on event handling. I'm putting the link here so it doesn't get lost later on.

Hi. This set of examples is great. It is helping so much. Though I seem to be having a problem with MBE50. No p[articles are showing. I do have the video set to "Particles All"

Would be nice

Hi. I was looking at your ItemsVariants class for the bitwise operations to get/set metadata and I noticed that you were using 0x07 for the upper 2 bits of data (fullnessBits):

  @Override
  public String getItemStackDisplayName(ItemStack stack)
  {
    String s = ("" + I18n.translateToLocal(this.getUnlocalizedName(stack) + ".name")).trim();  // this is depecrated, but I don't know what replaces it...
    int metadata = stack.getMetadata();
    int fullnessBits = (metadata >> 2) & 0x07;
    EnumBottleFullness fullness = EnumBottleFullness.byMetadata(fullnessBits);
    s += "(" + fullness.getDescription() + ")";
    return s;
  }

But this is unnecessary, as you could use 0x03 as you did for the lower 2 bits in the getUnlocalizedName() method, since you right-shifted the bits:

  public String getUnlocalizedName(ItemStack stack)
  {
    int metadata = stack.getMetadata();
    int contentsBits = metadata & 0x03;
    int fullnessBits = (metadata >> 2) & 0x07;

    EnumBottleContents contents = EnumBottleContents.byMetadata(contentsBits);
    return super.getUnlocalizedName() + "." + contents.getName();
  }

The GameRegistry.register() function is set private. And the example may seem to be confused.

used this project and the textures don't show in mincraft

Hi. First, awesome tutorial!

I use 1-10-2final branch. I see that "1.10.2-12.18.1.2011" forge is used. I see that most mods are against "12.18.3.2185". If I changed version in build.gradle build failed. I was trying to change mapping to "stable_29" (following by info at http://export.mcpbot.bspk.rs) but it didn't help.

I have still a lot of errors:

.../MinecraftByExample/build/sources/main/java/minecraftbyexample/mbe06_redstone/input/TileEntityRedstoneColouredLamp.java:48: error: cannot find symbol

I'm new in modding. Do you have any idea what I screwed up? Can I use official forge for 1.10.2?

In reference to MinecraftByExample MBE21 (Link)

I would like to know how you generated the Gem Vertices and/or how can I use an .obj model instead?

Hello, and sorry if this is not the proper place to post this. I was following your nice tutorial to start on modded minecraft. I was able to complete the first task, except for the language file. I am following the example step by step, but I changed the names a bit so that I can learn better what's going on.

The thing is I am registering the simple block as

blockSimple =new BlockSimple();
blockSimple.setUnlocalizedName("xfbe01_block_simple");
blockSimple.setRegistryName("xfbe01_block_simple");
ForgeRegistries.BLOCKS.register(blockSimple);
// We also need to create and register an ItemBlock for this block otherwise it won't appear in the inventory
itemBlockSimple = new ItemBlock(blockSimple);
itemBlockSimple.setRegistryName(blockSimple.getRegistryName());
ForgeRegistries.ITEMS.register(itemBlockSimple);

So the corresponding lang file (en_US.lang) contains:

tile.xfbe01_block_simple.name=XFBE01 Block Simple

No errors appear when I run minecraft, it's simply that the displayed name of the block is tile.xfbe01_block_simple.name.
I've checked that the language is set to english (US), I've tried with different names... I've tried in Linux and in Windows... but I never get to pick up the name provided in the lang file.

Do you have any idea on this? You can see my whole file structure at https://github.com/Xaunther/XauntherFBE. I just ran out of ideas to solve it...

Thanks!

Could you please add an example for importing obj (wavefront)custom block ?

Thanks in advance

I'm making something which needs 3 inputs. I'm wondering about extending Comparator.

1. Is it possible to just "tint" with colour the inbuilt one and override the output generation?
2. If I have to make a new one another way, how do I get the side input? For example, copying the Redstone meter?
3. Is there any texture resources to start making something similar to a built-in comparator?

As far as I know there are more than one threads rendering the world. But in MBE05, there's only one CompositeModel instance. Since handleBlockState always returns this, different blocks affect each other when rendered in different threads. For example:

• Thread 1 is rendering one block at A position. Call handleBlockState.
• Thread 2 is rendering another block at B position. Call handleBlockState.
• Thread 1 continue rendering. Call getGeneralQuads. Here, states of block at B position is saved, but rendered at A position.

Solution:
Although it costs more space, a new IBakedModel should be returned by handleBlockState, I suppose.

When I added the source from the 1.10.2 branch to my workspace, I found that there were a lot of errors in it.
For example, Minecraft#thePlayer is used instead of Minecraft#player, theWorld instead world.
In 1.11.2 there is no such branch.

Examples for developing mods with Architectury( a project that permit to do cross platform (fabric and forge) mods) would be very useful.

Loaded up MinecraftByExample with 8.1. Running in eclipse I get the above compliation error in HUDtextRenderer.java and MenuItemCameraTransforms.java

CWE-829: Inclusion of Functionality from Untrusted Control Sphere

It seems like this is actually a pretty big issue across the entire Modded Minecraft Ecosystem because there seem to be a lot of mods using this project as a starter structure for their own:

• MinecraftForge/CoreMods#4
• SlimeKnights/TinkersConstruct#3764

The BlockRedstoneColouredLamp works fine with any redstone that runs straight to the Lamp. Just like the ordinary RedstoneLamp. But redstone "passing by" visually connects to the lamp but in fact doesn't affect the lamp. Redstone "just passing by" also has no effect on regulat RedstoneLamps. But unlike BlockRedstoneColouredLamp they don't make the redstone attach to it visually in that case.

Imho the BlockRedstoneColouredLamp should not return true on canConnectRedstone at all. This way its visual representation would not wrongly suggest that it connects to passing redstone.

I'm new to modding, so this may be something stupid. I can clone and build MBE such that it will run using gradlew runClient just fine. If I copy the build/libs/minecraftbyexample-1.12.2a.jar and put it into my minecraft/mods directory then minecraft crashes with this error:

Changing from .txt to one of the github-supported rich rendering formats like .md will make the notes easier to read and (probably) more pleasing to search engines. Furthermore, if you name the files README.md, github will auto-render it beneath the directory's file list as people browse the repo on the website.

I'd be willing to help with the conversion/formatting (as a pull request) if you approve a plan.

I build your project and tested it with this1.16.4-forge-35.1.0 Forge Version.
After a while i run in that Error net.minecraftforge.fml.common.ObfuscationReflectionHelper$UnableToFindFieldException caused by java.lang.NoSuchFieldException: world.

Does I miss something? Or is this version still in development?

The full crash-log.

If you try to make a wall with the camo blocks, the camo block does not show the other camo block's disguise. For example. If i place 1 stone and place a camo block on that, it turns to stone. But if i add ANOTHER camo block on the one i placed, the default stone texture is placed....

One thing I want to make clear: this is a great resource and it's extremely helpful for someone getting into modding. The only other version I've modded successfully is 1.7.10 and this is a great resource to get started on modern versions.

But back on track: recipe JSON files should be in resources\data\modname\recipes. At the moment, in the repository the folder is in the assets folder.

Thanks for putting this together...
This is the first time building/running the project...

Just FYI - Testing with 1.11.2 beta build (13.20.0.2227) the method signature for getSubItems changed to be a NonNullList:
public void getSubItems(Item itemIn, CreativeTabs tab, NonNullList<ItemStack> subItems)

Since this method does not currently have the @Override attribute, the build did not flag an error when I tried to build with1.11.2 - but the item variants did not show up in the creative inventory since getSubItems was not correctly overriden.

Recommend adding the @Override attribute, to force an error if someone tries to build with 1.11.2, at least until such time as you choose to update your code to 1.11.2?

Is there a way that de cammo block base model also can rotated on the blockstate facing?
I have a block with the same behaviour but diffrent base model that is rotatable.

The copper texture has a 3 pixels in the top right that are not fully transparent which causes you to see through the texture from the side when being rendered in minecraft when following the 1.10.2 tutorial.

Erasing those 3 pixels fixed the model issue pretty easily. I learned something about minecraft textures I didn't know so I'm a bit happy about this 'bug'. =P

Example 05, the dynamic web model, seems to not work in branch 1.12.2 (and probably other earlier branches). When i place the block it just appears as the purple-black missing model block, the item in inventory is appearing normally tough (the cobweb icon).

I checked the code multiple times, and everything seems fine, but unless i am missing something, there is no such models/block/smartblock/webmodel file in your assets folder, a path which is referenced in block_3d_web_statemapper_name.json as the model path, and is also referenced in the code of ModelLoader3DWeb class.

So, what is this "webmodel" file supposed to contain? I even tried creating that file myself but still the problem in game persists. I am not even sure why you would have to make a reference to this smartmodel/webmodel file in the statemapper, so because of that missing file in your repository i got very confused. Maybe it got accidentally deleted? If not then i have got no clue how to solve the issue, because the code is identical to yours. Any idea how to solve that?
Cheers

I am pretty sure you have this, I am just not sure what classes. I looked at Entities and Models and tried to look at those classes but I am a bit lost and now doubting if I am in the right spot.

For reference I am new to this and trying to learn so I am sorry if I was in the right place just not understanding.

My deepest thanks to all of you for having created this! It is a big help in my minecraft modding endeavour! Though I must admitt that I am very surprised to see that you have no .gitignore file here. Isn't that a very important part of having your minecraft mod on Github? I have had many different suggestions on how I should go forward with the .gitignore file and I am unsure how to go forward...

I do know that having your mod on Github is by no means a requirement when it comes to modding but knowing how helpful I found looking at the mods here on Github I want to help others going through the same process.

All of your help would be deeply appreciated!

This is a great resource you guys have setup here - props and thanks!

Any chance you'll be adding some updated things for 1.9? I'm especially stumped with how to deal with how you have to register Blocks and ItemBlocks separately and could use some help (or a point in the right direction).

Thanks and very nice work here again!

How to add new potion effects. There are a lot of examples of this being done in other mods but not really any tutorial resources on it, to my knowledge. It might help me and others to have it, if you think it's a good idea.

I've read the Notes.txt but I don't understand this. Can someone help me? My IDE is Eclipse.

EDIT: Figured it out

Since MessageHandlerOnClient uses client only class Minecraft, it would throw a ClassNotFoundException in a dedicated server when MessageHandlerOnClient is loaded. But StartupCommon uses MessageHandlerOnClient. So I doubt whether these codes work on dedicated servers.

I would use different network registration at dedicated server and client. At client, I would use MBE60 codes:

simpleNetworkWrapper.registerMessage(MessageHandlerOnServer.class, AirstrikeMessageToServer.class,
                                          AIRSTRIKE_MESSAGE_ID, Side.SERVER);
simpleNetworkWrapper.registerMessage(MessageHandlerOnClient.class, TargetEffectMessageToClient.class,
                                          TARGET_EFFECT_MESSAGE_ID, Side.CLIENT);

While at a dedicated server, I would use this:

simpleNetworkWrapper.registerMessage(MessageHandlerOnServer.class, AirstrikeMessageToServer.class,
                                          AIRSTRIKE_MESSAGE_ID, Side.SERVER);
simpleNetworkWrapper.registerMessage(MessageHandlerOnServerButHandleClientMessage.class, TargetEffectMessageToClient.class,
                                          TARGET_EFFECT_MESSAGE_ID, Side.CLIENT);

And define MessageHandlerOnServerButHandleClientMessage:

public class MessageHandlerOnServerButHandleClientMessage implements IMessageHandler<TargetEffectMessageToClient, IMessage> {
  public IMessage onMessage(final TargetEffectMessageToClient message, MessageContext ctx) {
    throw new RuntimeException("Cannot handle TargetEffectMessageToClient at a dedicated server.");
  }
}

I was playing around with your examples to get a grip on changes to forge (I'm coming from 1.8, a lot has changed!). I noticed you're using runWhenOn to bind client only events. Now I'm not entirely sure why it's deprecated yet but I imagined it was due to the lack of refferant checks the original method had. I'm not very keen on the DistExecuter in general, I've had a brief look at the code and it seems super hacky but with the lack of any other methods to check sidedness in 1.16.x I guess it's what we've got.

That said, I've updated your examples to use safeRunWhenOn if that's something you'd prefer to use.

@TheGreyGhost
I've looked at everything, nothing seems to be wrong but the textures. Purple and Black. I'm using Eclipse and I put my project on github for this purpose, please help as soon as possible. https://github.com/HXGamer/hogn.git <--- mod

What I've checked so far:
JSON: YES
Spelling:YES
Check pictures for corruption:YES
If above, I've checked it and made sure it's not the issue.
Here's the log: http://pastebin.com/PQMmuWx7

Please help, I've looked at everything

I found several cases where the code of an example is commented out entirely, like here https://github.com/TheGreyGhost/MinecraftByExample/blob/master/src/main/java/minecraftbyexample/mbe35_recipes/StartupCommon.java .
Why is that? It's hard to read without the proper colors ...

When I put the HUD overlay item into my hotbar in creative, I no longer am able to access the create inventory.
