I am hosting a server with my mod on it. I have the exact same built version of that mod on my client. Both the server and the client are using Forge version 27.0.17. My mod specifies that it is made for Forge version 27.

 

Channels [luckyblock:main] rejected their server side version number

is the error I get on the client whenever I try to join the server. Forge tells me that I have a mismatched mod channel list.

I'm wondering if my dependencies in my mods.toml might be the cause of this:

Where you register your network channels. I don't know your code, you wrote it so I would assume you know.

Expand  

Ohhhh, that kind of code, I thought you meant a code.

  

private static final String PROTOCOL_VERSION = "490";

public static final SimpleChannel INSTANCE = NetworkRegistry.newSimpleChannel(
        new ResourceLocation(MyMod.MODID, "main"),
        () -> PROTOCOL_VERSION,
        PROTOCOL_VERSION::equals,
        PROTOCOL_VERSION::equals
);

 

I looked up the protocol versions and found that 490 is for 1.14.3. I also tried version 1 (from the example code).

I have a feeling that I shouldn't be comparing the protocol versions directly and should actually be checking if the version is one of many versions. I just don't know what those versions would be.

This is for your own version. So that you can check if certain versions of your mod are compatible when used together on server / client.

So really, this should work, unless you are starting a vanilla server.

Expand  

 

From the docs: "Here, we simply compare with the PROTOCOL_VERSION field directly, meaning that the client and server  PROTOCOL_VERSIONs must always match or FML will deny login."

 

No, I'm not starting a vanilla server.

First thing I noticed is that all your packets use the same packet ID ("index").

Then, you are registering your SimpleChannel in a static intializer. Do not do this, you have no control over when this code runs. It should happen during FMLCommonSetupEvent.

You then register your packets only on the client (FMLClientSetupEvent). This must also happen on both sides.

Expand  

This fixed my problem, but do you also know why none of my server commands are being registered?

For a start, do not use @OnlyIn on your commands. In fact, do not use @OnlyIn at all.

You register your FMLServerStartingEvent event handler to the mod event bus, but that event is fired on the forge event bus.

My new code (in the repo) throws this error on the server whenever I try to send a packet to a player 

Received invalid message me.jasonhaxstuff.luckyblock.packets.JumpScarePKT

Nevermind. I had to register the packets on the `FMLServerStartingEvent` event. That fixed it.

Ohhhhhh! Whenever you said "You then register your packets only on the client (FMLClientSetupEvent)." I though you meant that I should do that.

      Mowzie's Mobs for 1.16.5 crashes when using most items that have custom animations

      By Joeyman2525 · Posted

      My Crazy Craft Updated pack for 1.16.5 crashes whenever I use items from Mowzie's Mobs that have animations. Specifically the ones that I have tried are the Ice Crystal and the Axe of a Thousand Metals. The crash only happens when I use the ability of it, aka right click, which triggers the animation. I should note that I added around 50 other mods to the pack, two of which are the Female Gender mod and More Player Models. Could they be the source of the crash? Here is the crash log: https://mclo.gs/ZhsC793

      [1.21.5] The texture of the item is not loading.

      By Loghan · Posted

      Hey! I noticed you're trying to register your alexandrite item and possibly set its resource location manually with setId(...). I wanted to help clarify a few things that might simplify your code and avoid errors. ✅ The issue: You're using setId(...) inside the item registration like this:   public static final RegistryObject<Item> ALEXANDRITE = ITEMS.register("alexandrite", () -> new Item(new Item.Properties().useItemDescriptionPrefix() .setId(ResourceKey.create(Registries.ITEM, ResourceLocation.fromNamespaceAndPath(TutorialMod.MOD_ID, "alexandrite"))))); But: Item.Properties does not have a setId(...) method — this line will either fail or do nothing meaningful. useItemDescriptionPrefix() is mostly used for translation keys (like "item.modid.name") but isn't needed unless you have a very specific reason. 🛠 The fix: You only need to register your item like this:   public static final RegistryObject<Item> ALEXANDRITE = ITEMS.register("alexandrite", () -> new Item(new Item.Properties())); Forge automatically handles the ResourceLocation (modid:alexandrite) based on the name passed into .register(...), so there’s no need to manually assign it. 📝 For the texture: Make sure you have this file in your resources: src/main/resources/assets/tutorialmod/models/item/alexandrite.json { "parent": "item/generated", "textures": { "layer0": "tutorialmod:item/alexandrite" } } And your texture PNG goes here: src/main/resources/assets/tutorialmod/textures/item/alexandrite.png 🌍 For the name in-game: Add this to your en_us.json under: src/main/resources/assets/tutorialmod/lang/en_us.json { "item.tutorialmod.alexandrite": "Alexandrite" }   Note: if im wrong about the issues you are encountering, i apologize.

      "Custom Item Appears Transparent and Clips Through Blocks When Held — Fixed by Adding 'render_type': 'minecraft:cutout'

      By Loghan · Posted

      🛠️ Fix for Transparent or Clipping Item Render Issues When Held in First Person (Forge 1.20+) Hey everyone! I recently ran into a frustrating bug while making a custom item (a rocket) for my Forge mod, and I’m sharing the fix because it’s a bit obscure — and it worked wonders. 💥 The Problem: My item rendered semi-transparent and see-through — but only in first person. It also clipped through nearby blocks when held, unlike default items like swords or leads. The texture file was confirmed to be fully opaque (alpha 255), so the issue wasn’t the PNG itself. Interestingly, when no texture was present and the default purple-black checkerboard appeared, the clipping issue disappeared. ✅ The Fix: I ended up resolving it by randomly trying something I found on a Forge forum post about block rendering. I added this property to my item's model JSON — even though it's typically only used for blocks: { "parent": "item/generated", "textures": { "layer0": "farbeyond:item/rocket_item" }, "render_type": "minecraft:cutout" } Boom. That single line forced the item to render using a proper opaque (cutout) layer, removing all the unwanted transparency and clipping behavior in first person. 🙌 Credit: I originally found the "render_type" trick mentioned here, in a block rendering context: 👉 https://forums.minecraftforge.net/topic/149644-1201-help-with-transparent-blocks/ Even though it was meant for blocks, I thought, why not try it on an item? And it worked! Big thanks to the poster — this fix wouldn’t have happened without that tip. Hopefully this helps anyone else stuck on a weird rendering bug like I was. This isn’t a common item solution, so feel free to share it further. I’d love to know if it works for you too.
