can i see that ? (the code)

 

also dont be afraid to debug a lot, println a lot maybe you cna stpo something weird

Wait I thought you meant in game, like "You actually put something in the bag didnt you?" anyway heres the code:

@Override
public void openChest()
{
	if(bagpack.hasTagCompound())
	{
		readFromNBT(bagpack.getTagCompound());//Bag pack has some info for the inventory
		System.out.println("call3");
	}
	else
	{
		bagpack.stackTagCompound = new NBTTagCompound();
		System.out.println("call2");

	}
}

@Override
public void closeChest()
{
	if(! bagpack.hasTagCompound())
	{
		//Should never be reached, since done when opening the first time
		bagpack.setTagCompound(writeToNBT(new NBTTagCompound()));
		System.out.println("call");
	}
	else
	{//We made changes to the inventory, save them
		System.out.println("call4");
		writeToNBT(bagpack.getTagCompound());
	}

well ok so at some point you will set a new nbt to yout bagpack

...

but nothign is ever set inside that :\

so what you have to do is something like this:

ItemStack toStore
ItemStack bagpack;
toStore.writeToNBT(bagpack.getTagCompound());

that will take the first itemStack and write it inside the tagCompound of the bagpack.

 

to read it from the nbt:

ItemStack s;
s.readFromNBT(bagpack.getTagCompound());

 

if you are dealing with a IInventory:

 

 

utility method that go in your IInventory:

public NBTTagList writeToNBT(NBTTagList par1NBTTagList)
    {
        int i;
        NBTTagCompound nbttagcompound;

        for (i = 0; i < this.equip.length; ++i)
        {
            if (this.equip[i] != null)
            {
                nbttagcompound = new NBTTagCompound();
                nbttagcompound.setByte("Slot", (byte)(i));
                this.equip[i].writeToNBT(nbttagcompound);
                par1NBTTagList.appendTag(nbttagcompound);
            }
        }

        return par1NBTTagList;
    }

    /**
     * Reads from the given tag list and fills the slots in the inventory with the correct items.
     */
    public void readFromNBT(NBTTagList par1NBTTagList)
    {
        this.equip = new ItemStack[getSizeInventory()];

        for (int i = 0; i < par1NBTTagList.tagCount(); ++i)
        {
            NBTTagCompound nbttagcompound = (NBTTagCompound)par1NBTTagList.tagAt(i);
            int j = nbttagcompound.getByte("Slot") & 255;
            ItemStack itemstack = ItemStack.loadItemStackFromNBT(nbttagcompound);

            if (itemstack != null)
            {
                if (j >= 0 && j < this.equip.length)
                {
                    this.equip[j] = itemstack;
                }
            }
        }
    }

 

 

now if you have a whole inventory:

ItemStack bagpack;
MyInventory inv;
NBTTagList theInventory = new NBTTagList();
inv.writeToNbt(theInventory);
bagpack.getTagCompound().setTag("theBagpackInventory", theInventory);

 

and to read:

ItemStack bagpack;
MyInventory inv;
NBTTagList theInventory = (NBTTagList)bagpack.getTagCompound.getTag("theBagpackInventory");
inv.readFromNbt(theInventory);
//here inv contain the original inventory

well you have to place it where it makes sens, obviously this probably wont go inside a new mob you create.

 

whats the goal of the bagpack, to store 1 item ? 20 item ? 500 items? i imagine you want the content to be updated in the bagpack when you close the gui, the Container class has a onContainerClosed method, might be a good idea to save there, maybe you should be loading when the container opens ?

Stores 27 items. " the Container class has a onContainerClosed method, might be a good idea to save there, maybe you should be loading when the container opens ?" Thats what Im currently doing. I meant which bits should I replace w/ your code

well i guess you could place that inside closechest suince your onContainerClosed calls this anyway, but basicly anywhere where it should make sens to do it. as long as it works

i have no idea

do you understand what the code me n gotolink are talking about ?

do you understand what it does ?

if not which part are you still confused with ?

how are your java skills? beginner intermediate advance ?

because maybe its just a question of practice to know what to place where

 

did you try anything ? println to see what placing the code at certain place does ?

"do you understand what the code me n gotolink are talking about ?

Not enough to be able to implement it correctly

"how are your java skills? beginner intermediate advance ?" Im pretty familiar w/ all the common stuff, so sorta of intermediate/high beginner

 

"if not which part are you still confused with ?" Just where to put it really aha

I already am if it dosent have a tagCompound though?

	if(! bagpack.hasTagCompound())
	{
		bagpack.setTagCompound(writeToNBT(new NBTTagCompound()));
		System.out.println("call");
	}
	else
	{
		System.out.println("call4");
		writeToNBT(bagpack.getTagCompound());
	}

if(!bagpack.hasTagCompound()){
    bagpack.stackTagCompoud = new NBtTagCompound();
}
toStore.writeToNBT(bagpack.getTagCompound());

the first if create the compound if needed, then you can write for sure as you KNOW theres one

    • I'm developing a dimension, but it's kinda resource intensive so some times during player teleporting it lags behind making the player phase down into the void, so im trying to implement some kind of pregeneration to force the game loading a small set of chunks in the are the player will teleport to. Some of the things i've tried like using ServerLevel and ServerChunkCache methods like getChunk() dont actually trigger chunk generation if the chunk isn't already on persistent storage (already generated) or placing tickets, but that doesn't work either. Ideally i should be able to check when the task has ended too. I've peeked around some pregen engines, but they're too complex for my current understanding of the system of which I have just a basic understanding (how ServerLevel ,ServerChunkCache  and ChunkMap work) of. Any tips or other classes I should be looking into to understand how to do this correctly?

    • Way back in the Forge 1.17 days, work started for adding JPMS (Java Platform Module Support) to ModLauncher and ForgeModLoader. This has been used internally by Forge and some libraries for a while now, but mods (those with mods.toml specifically) have not been able to take advantage of it. As of Forge 1.21.1 and 1.21.3, this is now possible!   What is JPMS and what does it mean for modders? JPMS is the Java Platform Module System, introduced in Java 9. It allows you to define modules, which are collections of packages and resources that can be exported or hidden from other modules. This allows for much more fine-tuned control over visibility, cleaner syntax for service declarations and support for sealed types across packages. For example, you might have a mod with a module called `com.example.mod` that exports `com.example.mod.api` and `com.example.mod.impl` to other mods, but hides `com.example.mod.internal` from them. This would allow you to have a clean API for other mods to use, while keeping your internal implementation details hidden from IDE hints, helping prevent accidental usage of internals that might break without prior notice. This is particularly useful if you'd like to use public records with module-private constructors or partially module-private record components, as you can create a sealed interface that only your record implements, having the interface be exported and the record hidden. It's also nice for declaring and using services, as you'll get compile-time errors from the Java compiler for typos and the like, rather than deferring to runtime errors. In more advanced cases, you can also have public methods that are only accessible to specific other modules -- handy if you want internal interactions between multiple of your own mods.   How do I bypass it? We understand there may be drama in implementing a system that prevents mods from accessing each other's internals when necessary (like when a mod is abandoned or you need to fix a compat issue) -- after all, we are already modding a game that doesn't have explicit support for Java mods yet. We have already thought of this and are offering APIs from day one to selectively bypass module restrictions. Let me be clear: Forge mods are not required to use JPMS. If you don't want to use it, you don't have to. The default behaviour is to have fully open, fully exported automatic modules. In Java, you can use the `Add-Opens` and `Add-Exports` manifest attributes to selectively bypass module restrictions of other mods at launch time, and we've added explicit support for these when loading your Forge mods. At compile-time, you can use existing solutions such as the extra-java-module-info Gradle plugin to deal with non-modular dependencies and add extra opens and exports to other modules. Here's an example on how to make the internal package `com.example.examplemod.internal` open to your mod in your build.gradle: tasks.named('jar', Jar) { manifest { attributes([ 'Add-Opens' : 'com.example.examplemod/com.example.examplemod.internal' 'Specification-Title' : mod_id, 'Specification-Vendor' : mod_authors // (...) ]) } } With the above in your mod's jar manifest, you can now reflectively access the classes inside that internal package. Multiple entries are separated with a space, as per Java's official spec. You can also use Add-Exports to directly call without reflection, however you'd need to use the Gradle plugin mentioned earlier to be able to compile. The syntax for Add-Exports is the same as Add-Opens, and instructions for the compile-time step with the Gradle plugin are detailed later in this post. Remember to prefer the opens and exports keywords inside module-info.java for sources you control. The Add-Opens/Add-Exports attributes are only intended for forcing open other mods.   What else is new with module support? Previously, the runtime module name was always forced to the first mod ID in your `mods.toml` file and all packages were forced fully open and exported. Module names are now distinguished from mod IDs, meaning the module name in your module-info.java can be different from the mod ID in your `mods.toml`. This allows you to have a more descriptive module name that doesn't have to be the same as your mod ID, however we strongly recommend including your mod ID as part of your module name to aid troubleshooting. The `Automatic-Module-Name` manifest attribute is now also honoured, allowing you to specify a module name for your mod without needing to create a `module-info.java` file. This is particularly useful for mods that don't care about JPMS features but want to have a more descriptive module name and easier integration with other mods that do use JPMS.   How do I use it? The first step is to create a `module-info.java` file in your mod's source directory. This file should be in the same package as your main mod class, and should look something like this: open module com.example.examplemod { requires net.minecraftforge.eventbus; requires net.minecraftforge.fmlcore; requires net.minecraftforge.forge; requires net.minecraftforge.javafmlmod; requires net.minecraftforge.mergetool.api; requires org.slf4j; requires logging; } For now, we're leaving the whole module open to reflection, which is a good starting point. When we know we want to close something off, we can remove the open modifier from the module and open or export individual packages instead. Remember that you need to be open to Forge (module name net.minecraftforge.forge), otherwise it can't call your mod's constructor. Next is fixing modules in Gradle. While Forge and Java support modules properly, Gradle does not put automatic modules on the module path by default, meaning that the logging module (from com.mojang:logging) is not found. To fix this, add the Gradle plugin and add a compile-time module definition for that Mojang library: plugins { // (...) id 'org.gradlex.extra-java-module-info' version "1.9" } // (...) extraJavaModuleInfo { failOnMissingModuleInfo = false automaticModule("com.mojang:logging", "logging") } The automatic module override specified in your build.gradle should match the runtime one to avoid errors. You can do the same for any library or mod dependency that is missing either a module-info or explicit Automatic-Module-Name, however be aware that you may need to update your mod once said library adds one. That's all you need to get started with module support in your mods. You can learn more about modules and how to use them at dev.java.

    • When I came across the 'Exit Code: I got a 1 error in my Minecraft mods, so I decided to figure out what was wrong. First, I took a look at the logs. In the mods folder (usually where you'd find logs or crash reports), I found the latest.log file or the corresponding crash report. I read it through carefully, looking for any lines with errors or warnings. Then I checked the Minecraft Forge support site, where you can often find info on what causes errors and how to fix them. I then disabled half of my mods and tried running the game. If the error disappeared, it meant that the problem was with the disabled mod. I repeated this several times to find the problem mod.
