Okay so I have a custom furnace that smelts 2 items into 1 and I'm currently have a bit of an issue with it. The furnace is sometimes doubling the output when I only want it to output a single item. I always end up with 15 instead of 8. I believe the first one it makes is doing it right but then after that it outputs 2 instead of one. It also doesn't always work, sometimes when it is placed or after the items are taken out and the GUI closed and reopened it will no longer smelt items. Then most of the time if I pull the items it smelted out they just disappear out of the players inventory after you close the GUI. Then the last issue I'm having is when the block is broken the items won't drop on the ground, they just vanish into thin air. All of the source code for my furnace will be listed below(if i missed anything you need please let me know), if anybody could help me out that would be greatly appreciated and you will be mentioned in the credits of my finished mod once it's able to be released. BLOCK CLASS: RECIPE CLASS{the recipes in here are for testing purposes}: CONTAINER CLASS: GUI CLASS: TILE ENTITY:

Steps: 1- Have a capability. 2 - Get the capability. Example: public static IExample getCapability(Entity entityIn) { return entityIn.getCapability(CAPABILITY).orElseThrow(NullPointerException::new); } 3 - Use an event. Example: PlayerTickEvent. 4 - Kill the player. (/ kill) 5 - The game throws NullPointerException.

I'm not sure why, but whenver I run the command ./gradlew setDecompWorkspace, I get this error: ERROR: JAVA_HOME is set to an invalid directory: C:\Program Files\Java\jdk1.8.0_191\bin Please set the JAVA_HOME variable in your environment to match the location of your Java installation. I've added the JAVA_HOME variable under my System Environment Variables as this: JAVA_HOME=C:\Program Files\Java\jdk1.8.0_191\, my system path contains this: C:\Program Files\Java\jdk1.8.0_191\bin;C:\Program Files\Java\jdk1.8.0_191

Strangely, I can't open chests anymore since updated to 14.1.2604 of Forge.

I've noticed a bug every so often I try to create a new world or enter a world. The game would finish creating it, but then when it gets to sending me to the world, it spits out this long error and it displays '0%' on the screen. I'm using Forge 14.21.1.2413 with several mods that I'm using to create a modpack. Here's my FML Log

There's currently no way to specify custom config GUI entries for properties created through the annotation-based config system without reflecting the Configuration instance from ConfigManager and calling Property#setConfigEntryClass manually. Could an annotation be added that allows a custom Property.Type or IConfigEntry class to be specified for the generated Property? On a related note, it's currently not possible to use GuiConfigEntries.BooleanEntry, GuiConfigEntries.CycleValueEntry or GuiConfigEntries.ChatColorEntry with Property#setConfigEntryClass because their constructors aren't public. Attempting to do so throws a NoSuchMethodException for the constructor when the config GUI is opened. It's also not possible to extend these and add a public constructor, since the constructors are private or package-private. Edit: Reported this on GitHub here.

The behaviors are different, so one is (probably) more wrong. The difference looks to be this: ItemStackHolderInjector uses Field f = clazz.getField(annotationTarget); and ObjectHolderRegistry uses Field f = clazz.getDeclaredField(annotationTarget);. Switching ItemStackHolderInjector to use Class::getDeclaredField like ObjectHolderRegistry would, at the very least, save future modders the confusion I felt when java told me that the field that is right there doesn't exist. This would also enable the use case where I discovered this: private fields populated with ItemStacks for use in recipe registration. Because I've caught Kotlin fever, the linked code there is in Kotlin, but compiles to the equivalent private static member (with a private set method and a public get method, as of the linked commit; I plan to make it fully private, this was just the work commit where I caught this issue). I can make this an issue and/or PR against the MinecraftForge GitHub, but I didn't want to needlessly clutter the repository if this is considered a non-issue. Consider my vote to apply this one-line patch, though. I haven't tested this, because I don't currently have the setup required to build a custom version of forge and test it.

I've made a mod with a bunch of armor items that worked fine, until I tried updating the mod to 1.12. I dug through the code (ctrl + H is my friend) and found that the only place where Item#onArmorTick (a method that should update the armor every tick) gets called is in InventoryPlayer#setPickedItemStack, a method for handling pickblocking (so I could only fly my jetpack for a split second while pickblocking, which is no good), with a message from Forge saying "FORGE: Tick armor on animation ticks". How would I go about doing that (I don't have a separate class for rendering my armors or anything)? Also, I'm using forge-1.12-14.21.0.2333-mdk, which I know isn't the latest version, but that brings me onto my next problem: whenever I try setting up anything later than 2333 (using gradlew setupDecompWorkspace), it fails, giving me this: To honour the JVM settings for this build a new JVM will be forked.

Hey everyone, I am having problems with the new way of registering blocks. I can register items just fine, but blocks seem to fail (I get no console error, but my blocks are not appearing in my creative tab, nor can I give them to player via eventhandler) Registering the blocks (the events are getting called, I double checked that) @SubscribeEvent public void registerBlocks(RegistryEvent.Register<Block> event) { event.getRegistry().registerAll(blockkitchen); } @SubscribeEvent public void registerModels(ModelRegistryEvent event) { registerBlock(blockkitchen); } private void registerBlock(Block block) { ModelLoader.setCustomModelResourceLocation(Item.getItemFromBlock(block), 0, new ModelResourceLocation(block.getRegistryName(),"inventory")); } Important parts of the block class public class BlockKitchen extends ProgressingBlock{ public BlockKitchen() { super(Material.PISTON, "blockkitchen"); } } public class ProgressingBlock extends Block { public ProgressingBlock(Material materialIn, String name) { super(materialIn); setRegistryName(name); setUnlocalizedName(name); setCreativeTab(ProgressingPlayer.CREATIVE_TAB); } } assets/progressingplayer/blockstates/blockkitchen.json { "variants": { "normal": { "model": "progressingplayer:blockkitchen" } } } assets/progressingplayer/models/block/blockkitchen.json { "parent": "block/cube_all", "textures": { "all": "progressingplayer:blocks/blockkitchen" } } assets/progressingplayer/models/item/blockkitchen.json { "parent":"progressingplayer:block/blockkitchen", "display": { "thirdperson": { "rotation": [ 10, -45, 170 ], "translation": [ 0, 1.5, -2.75 ], "scale": [ 0.375, 0.375, 0.375 ] } } } texture is under assets/progressingplayer/textures/blocks/blockkitchen.json Any help is appreciated!

Hey there, I am having problems registering the textures for my items. I know that I am missing something seriously obvious and hope that some1 can point me in the right direction. I got the following item-class public class ItemLearnScroll extends Item{ public ItemLearnScroll() { setMaxStackSize(1); setUnlocalizedName("learnscroll"); //For testing until i got my own tab setCreativeTab(CreativeTabs.FOOD); setRegistryName("learnscroll"); } } I register the item in the event @SubscribeEvent public void registerItems(RegistryEvent.Register<Item> event) { event.getRegistry().registerAll(ProgressingPlayer.ITEM_LEARN_SCROLL); } src/main/resources/assets/progressingplayer/models/item/learnscroll.json { "parent": "item/generated", "textures": { "layer0": "progressingplayer:items/learnscroll" } } The texture is located under src/main/resources/assets/progressingplayer/texures/items/learnscroll.png The item is registered, but got no texture This is the important error log I would be glad if someone could tell me where my error is.

Tried with the last Forge releases for Minecraft 1.10.2 and 1.11.2 ( Forge-12.18.3.2221 and Forge-13.20.0.2226 respectively). After death, you always respawn on negative X and Z coordinates (always northwest of the world spawn). How to reproduce the bug: 1. Start a new game. 2. Type the command /gamerule spawnRadius 5000 (for example). 3. Kill your character. 4. You respawn northwest of the world spawn on negative X and Z coordinates. Probably this has something to do with this issue: https://github.com/MinecraftForge/MinecraftForge/issues/2624

First, I want to say that I am viewing this site from an iPad. For some reason, on all posts, the user's avatar is on top of the text. This's is very odd and I cannot read the posts properly. Is this a bug, or could I somehow fix it? Also, how do you change your profile picture? Has that feature "vanished"? My (cute) cat avatar now looks like a waffle coming out of a toaster (aka: the default user avatar. :D) and I can't change that. Also, what happened to the "edit" button? I can't seem to edit any of my posts... D: Help?
