[SOLVED] [1.16.1] How to check if player can take a stack?

Recommended Posts

Hello,
What's the method that checks if player can take a certain stack? Like, if the player has 35.5 full stacks of dirt in their inventory, they still can take a stack of 32 blocks of dirt, but can't take either a stack of  33 dirt or a stack of any amount of cobblestone.

PlayerInventory#addItemStackToInventory 's javadoc:
"Adds the stack to the first empty slot in the player's inventory. Returns {@code false} if it's not possible to place the entire stack in the inventory."

Everything said above may be absolutely wrong. No rights reserved.

There's also:

ItemStackHandler.insert(stack, true).isEmpty()

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

Wait a minute... where can I get Minecraft source with javadoc? I've always used the .jar that is included in Forge MDK decompiled with Fernflower whenever I need to take a look at the game code.

Its in your external resources.

The first one is most of the code, client-extra.jar has a lot of the recipes, blockstates, and such.

Is this Eclipse? Apparently it has a different initial gradle script than IntelliJ - which I am using. I don't have two forge libraries. I only have one which contains the compiled .jar file.
And, yes, I also have client-extra and I use it as well.

Thank you all for trying to point me out where to find the source/recomp library, but I know where would it be, it is just not present in my External Libraries list now, when I work with 1.16.1. The only way I can access it is from file explorer. Maybe some configuration error. Anyway, this thread seems to have deviated much from the topic.

I wrote a function:

public static void giveItemStack(PlayerEntity player, ItemStack stack) {
  if (!player.addItemStackToInventory(stack)) {
    player.dropItem(stack, false);
  }
}

that now works pretty much the same as the /give command, which is exactly what I wanted.

PlayerInventory#addItemStackToInventory returns false if it's not possible to place the entire stack in the inventory.

Thanks @Dzuchun for that precious piece of information.

    • Hello. I'm using IntelliJ IDEA and making a mod for Forge 1.20.1 and I'm trying to make a GUI. I found that the Minecraft-related codes are all obfuscated and when setting up the workspace, Gradle did not execute Deobfuscation tasks like createMcpToSrg. Is this normal or a bug? Can anyone help me with this?
    • Hello! I'm trying to get a list of all entries registered in the infusion upgrade registry. Code can be found in github: https://github.com/ChamoisEST/MiningMadness/tree/1.20.1 Registry in common/registries/MMRegistries.java Event that calls the registry is in MiningMadness.java List of registered entries should be called in common/capabilities/infusion/InfusionCapabilityImplementation.java:getActiveInfusions() in the for loop. Is there any way to accomplish that? Thanks in advance!  
    • So, I am trying to create and add tags to my custom damage type, but looks like I made something wrong, since it crashing with error that "cannot register" damage type. Im trying to register it, and in datagen add tags, but it everytime crashing due to not register "grimtales:entropy". Full code there - https://github.com/undertakerJ/Grim-Tales-Forge ModDamageTypes class public class ModDamageTypes { public static final DeferredRegister<DamageType> DAMAGE_TYPES = DeferredRegister.create(Registries.DAMAGE_TYPE, GrimTales.MOD_ID); public static final ResourceKey<DamageType> ENTROPY_KEY = ResourceKey.create(Registries.DAMAGE_TYPE, new ResourceLocation(GrimTales.MOD_ID, "entropy")); public static final RegistryObject<DamageType> ENTROPY = DAMAGE_TYPES.register( "entropy", () -> new DamageType("entropy_effect", DamageScaling.ALWAYS, 1f, DamageEffects.HURT)); // // public static final DamageSource ENTROPY_SOURCE = new DamageSource(Holder.direct(ENTROPY.get())); public static void register(IEventBus eventBus) { DAMAGE_TYPES.register(eventBus); } } Datagen for damageTags public class ModDamageTagsProvider extends DamageTypeTagsProvider { public ModDamageTagsProvider( PackOutput p_270719_, CompletableFuture<HolderLookup.Provider> p_270256_, @Nullable ExistingFileHelper existingFileHelper) { super(p_270719_, p_270256_, GrimTales.MOD_ID, existingFileHelper); } @Override protected void addTags(HolderLookup.Provider pProvider) { this.tag(DamageTypeTags.BYPASSES_INVULNERABILITY).add(ModDamageTypes.ENTROPY_KEY); } } Datagen class it self   @Mod.EventBusSubscriber(modid = GrimTales.MOD_ID, bus = Mod.EventBusSubscriber.Bus.MOD) public class DataGenerators { @SubscribeEvent public static void gatherData(GatherDataEvent event){ DataGenerator generator = event.getGenerator(); PackOutput packOutput = generator.getPackOutput(); ExistingFileHelper helper = event.getExistingFileHelper(); CompletableFuture<HolderLookup.Provider> lookupProvider = event.getLookupProvider(); generator.addProvider(event.includeServer(), new ModDamageTagsProvider(packOutput, lookupProvider, helper)); } } And register class in main class public GrimTales() { IEventBus modEventBus = FMLJavaModLoadingContext.get().getModEventBus(); ModDamageTypes.register(modEventBus); modEventBus.addListener(this::commonSetup); MinecraftForge.EVENT_BUS.register(this); modEventBus.addListener(this::addCreative); }

    • Hi. I'm trying to play RLCraft with Optifine but my game keeps crashing on startup with Exit Code 1. The modpack was working fine yesterday, not sure what changed to make it not wanna work anymore. I was hoping someone here could help me figure out what's going wrong. If I remove Optifine, nothing changes, I still get the same errors. Thanks in advance. Crash Report (I only included the errors+fatal, I’m not sure if more is needed, please let me know): https://pastebin.ai/66ivknz0f4
