I'm trying to add a custom 5 by 5 crafting table into my forge 1.12.2 mod. I want so that when a button in the gui is pressed (The craft button) it crafts an item, this is run through the craftitem() function in the tile entity class. The problem however is that when I try to craft in game, is shows up the correct item but when I try to click it to take it out (or update the container in some way), everything resets to how it was before I pressed the craft button.

Can anyone see anything wrong or missing from my code that would cause this problem?

Buttons are client side only. The server doesn't know about the button press unless you tell it (with packets).

(Note: all you do is send a packet saying "this button was pressed" and let the server verify that everything's correct)

    • The specific issue is that items in my inventory wont stack properly. For instance, if I punch a tree down to collect wood, the first block I collected goes to my hand. So when I punch the second block of wood to collect it, it drops, but instead of stacking with the piece of wood already in my hand, it goes to the second slot in my hotbar instead. Another example is that I'll get some dirt, and then when I'm placing it down later I'll accidentally place a block where I don't want it. When I harvest it again, it doesn't go back to the stack that it came from on my hotbar, where it should have gone, but rather into my inventory. That means that if my inventory is full, then the dirt wont be picked up even though there should be space available in the stack I'm holding. The forge version I'm using is 40.3.0, for java 1.18.2. I'll leave the mods I'm using here, and I'd appreciate it if anybody can point me in the right direction in regards to figuring out how to fix this. I forgot to mention that I think it only happens on my server but I&#39;m not entirely sure. PLEASE HELP ME!

    • Hi everyone, I'm currently developing a Forge 1.21 mod for Minecraft and I want to display a custom HUD overlay for a minigame. My goal: When the game starts, all players should see an item/block icon (from the base game, not a custom texture) plus its name/text in the HUD – similar to how the bossbar overlay works. The HUD should appear centered above the hotbar (or at a similar prominent spot), and update dynamically (icon and name change as the target item changes). What I've tried: I looked at many online tutorials and several GitHub repos (e.g. SeasonHUD, MiniHUD), but most of them use NeoForge or Forge versions <1.20 that provide the IGuiOverlay API (e.g. implements IGuiOverlay, RegisterGuiOverlaysEvent). In Forge 1.21, it seems that neither IGuiOverlay nor RegisterGuiOverlaysEvent exist anymore – at least, I can't import them and they are missing from the docs and code completion. I tried using RenderLevelStageEvent as a workaround but it is probably not intended for custom HUDs. I am not using NeoForge, and switching the project to NeoForge is currently not an option for me. I tried to look at the original minecraft source code to see how elements like hearts, hotbar etc are drawn on the screen but I am too new to Minecraft modding to understand. What I'm looking for: What is the correct way to add a custom HUD element (icon + text) in Forge 1.21, given that the previous overlay API is missing? Is there a new recommended event, callback, or method in Forge 1.21 for custom HUD overlays, or is everyone just using a workaround? Is there a minimal open-source example repo for Forge 1.21 that demonstrates a working HUD overlay without relying on NeoForge or deprecated Forge APIs? My ideal solution: Centered HUD element with an in-game item/block icon (from the base game's assets, e.g. a diamond or any ItemStack / Item) and its name as text, with a transparent background rectangle. It should be visible to the players when the mini game is running. Easy to update the item (e.g. static variable or other method), so it can change dynamically during the game. Any help, code snippets, or up-to-date references would be really appreciated! If this is simply not possible right now in Forge 1.21, it would also help to know that for sure. Thank you very much in advance!
    • The simple answer is there is not an easy way. You would need to know how to program in Java, as well as at least some familiarity with how Forge works so you could port the differences. You would also need the sourcecode for the original mod, and permission from the author to modify it, if they did not use some sort of open source license. So it's not impossible, but it would take some effort, but doing so would open up a whole new world of possibilities for you!
    • Does it still crash if you remove holdmyitems? Looks like that mod doesn't work on a server as far as I can tell from the error.
