@V0idWa1k3r After some testing, I've found that the size I give it has no effect. Rather The List<Slot> object is being capped at 46 for some reason (so 0-45), As you can see here: as it doesn't tell me the spot where the size is being limited, I've no idea what's the problem. And It's only on this container. Could the problem be that I'm trying to add more than the player's Inventory and one other IInventory? Because the code you mentioned: IItemHandler deckboxInv = new ItemStackHandler(90); Is meant to be a placeholder for the inventory of the deckbox, which is what gets placed in the center slot I circled in pink at the start of this thread. I'm so lost here, This shouldn't be this complicated

@V0idWa1k3r ok, I changed the value to just a raw integer (so no variable) and it still gave me the same problem

@V0idWa1k3r Ok, so I'm trying to do something similar to the way horse inventories work, but encountering an error that doesn't really make sense. When I try to open the container, its throwing index out of bound exceptions as if the size of my inventory is 46. I've no idea where it got that number from because I originally set it to 52 slots. I tried setting the size to 100 for the sake of testing but it still only uses 46? I made an item that could hold 90 items plus the player's standard inventory and hotbar and didn't get this problem.

So, I have my item that stores card Items. I have part of the inventory that should only be available/interactable depending on whether a different slot has an item in it. (the inventory uses should then be the item in the determining slot). Maybe this screenshot would make things more clear, the spaces I want to enable and disable are circled in black and the special slot is circled in pink. I'd also like to change the gui background with this state change, but that comes later. How would I best go about this? Would I have to modify the capability to communicate between container and gui?

@Cadiboo Ok, so it's like an interface, but can do more?

I'm really confused, I was having issues trying to add my own inventory into the gui, so I decided to focus on the adding the player inventory, I copied my working code from my other item and now it duplicates my hotbar for some reason? I haven't had this problem before. After playing around with things, I figured out it translated my hotbar upward, pushing things into inappropriate item slots (building blocks into armor slots for example) and if there isn't any room left just overwrites what was there. This is my container code: package com.mekelaina.duelcraft.container; import com.mekelaina.duelcraft.card.CardCollection; import com.mekelaina.duelcraft.gui.GuiBinder; import com.mekelaina.duelcraft.items.ItemCard; import com.mekelaina.duelcraft.items.ItemDeckbox; import net.minecraft.entity.player.InventoryPlayer; import net.minecraft.inventory.Slot; import net.minecraft.item.ItemStack; import net.minecraft.nbt.NBTTagCompound; import net.minecraftforge.items.IItemHandler; import net.minecraftforge.items.SlotItemHandler; public class ContainerBinder extends CommonContainer { private int refX; private int refY; private InventoryPlayer playerInv; IItemHandler binderInv; //private GuiBinder GuiInstance; private static final int SLOT_WIDTH = 18; private static final int XSTART_DECKBOX = 140; private static final int YSTART_DECKBOX = 32; private static final int XSTART_BINDER = XSTART_DECKBOX + 112; private static final int YSTART_BINDER = YSTART_DECKBOX; private static final int XSTART_MID = XSTART_DECKBOX + 42; private static final int YSTART_MID = YSTART_DECKBOX + 13; private static final int numRows = 5; public ContainerBinder(InventoryPlayer playerInv, IItemHandler binderInv, int numSlots) { super(numSlots); this.playerInv = playerInv; this.binderInv = binderInv; int numColumns = numSlots / numRows; int xPosition; int yPosition; int index = 0; //int x = 0, y = 0; /*for(int x = 0; x < 10; x++) { for( int y = 0; y < 10; y++) { if(x < 5 && y < 5) { index = x + (y * 5); xPosition = XSTART_BINDER + ((x) * SLOT_WIDTH); yPosition = YSTART_BINDER + ((y) * SLOT_WIDTH); this.addSlotToContainer(new SlotItemHandler(binderInv, index, xPosition, yPosition) { @Override public boolean isItemValid(ItemStack stack) { if(stack.getItem() instanceof ItemCard && stack.hasTagCompound()) { NBTTagCompound nbt = stack.getTagCompound(); if(nbt.hasKey("Card_ID")) { String id = nbt.getString("Card_ID"); return !CardCollection.CARD_LIST.get(id).isExtraDeck(); } return true; } return false; } }); } else { } } } */ /*x++; y++;*/ /* xPosition = XSTART_MID + 50; yPosition = YSTART_MID + 10; index = x + (y * 5); index++; this.addSlotToContainer(new SlotItemHandler(binderInv, index, xPosition, yPosition) { @Override public boolean isItemValid(ItemStack stack) { if(stack.getItem() instanceof ItemDeckbox && stack.hasTagCompound()) { NBTTagCompound nbt = stack.getTagCompound(); if(nbt.hasKey("Card_ID")) { String id = nbt.getString("Card_ID"); return !CardCollection.CARD_LIST.get(id).isExtraDeck(); } return true; } return false; } });*/ // Player inventory for (int y = 0; y < 3; ++y) { for (int x = 0; x < 9; ++x) { this.addSlotToContainer(new Slot(playerInv, x + y * 9 + 9, (x * 18) + XSTART_DECKBOX, YSTART_DECKBOX + y * 18)); // x + y * 9 + 9 // 0 + 0 * 9 + 9 = 9 // 1 + 0 * 9 + 9 = 10 // 2 + 0 * 9 + 9 = 11 // 3 + 0 * 9 + 9 = 12 // 4 + 0 * 9 + 9 = 13 // 5 + 0 * 9 + 9 = 14 // 6 + 0 * 9 + 9 = 15 // 7 + 0 * 9 + 9 = 16 // 8 + 0 * 9 + 9 = 17 // 0 + 1 * 9 + 9 = 18 // 1 + 1 * 9 + 9 = 19 // 2 + 1 * 9 + 9 = 20 // 3 + 1 * 9 + 9 = 21 // 4 + 1 * 9 + 9 = 22 // 5 + 1 * 9 + 9 = 23 // 6 + 1 * 9 + 9 = 24 // 7 + 1 * 9 + 9 = 25 // 8 + 1 * 9 + 9 = 26 // ... } } // Hot bar for (int z = 0; z < 9; ++z) { this.addSlotToContainer(new Slot(playerInv, z, (z * 18) + XSTART_DECKBOX, YSTART_DECKBOX + 100)); } } public void setRefValues(int x, int y) { refX = x; refY = y; } }

@loordgek I'm aware of the forge page, that doesn't answer my question of how they work. Like its some kind of a d v a n c e d interface, but how its actually used I've no idea from the documentation. My problem is that I don't know how to use capabilities so I don't know what I need to do in my own capability to do what it is I want. Does anyone have a more beginner friendly explanation of what capabilities are and how they're used? Like forge provides a default item handling capability that can be used for storage, in theory, that should be all I need since I'm basically just trying to access three inventories at once. How can I get my gui and my container to talk to each other? one is server side and one is client side, but I need to update the server based on what the client does, right? If the player scrolls down in the inventory menu the container has to be updated to display the items accordingly. Can a capability extend another capability? can you implement more than one capability in an item? How does that work with attaching more than one capability to an item, block, or player? The documentation doesn't get me very far because I'm an idiot whose total modding experience can be summed up as about 5 minutes through a youtube tutorial (that's hyperbole, the point is I don't know what I'm doing nor what I'm looking for.)

@V0idWa1k3r ok, so how do the capabilities work? Like I'm still really confused about what they are exactly.

Ok, so my problem is that My item that stores items needs to be fairly complex. It has to be able to access 3 different inventories, Its own inventory, the player's inventory, and the inventory of an item in a specified slot (this item is a specific type). The size of these inventories are larger than the guis can fit, (i was planning to use a scroll bar kinda like the creative menus) and one set of inventory slots need to be "disabled" if there isn't an item in a specific slot. this will require some form of communication between the container and the gui and I'm really not sure how to go about this with an item. If it were a block, then you could use a tile entity to handle the communication. I know this sounds kinda vague but I'm just trying to figure out the best way to accomplish what I'm going for.

@V0idWa1k3r ?‍♀️ I can't believe I didn't think of that... It works now, I'm just dumb XD. Thanks to both you and @diesieben07.

@V0idWa1k3r ok... I realize that mistake, and it seems to have fixed the problem of not being able to type with whatever key is set as the inventory key, but the focusing part is still broken. If I manually (in code) set it focused it works fine, but it doesn't seem to be registering the mouse clicking even with canLoseFocus being set to true.

@diesieben07 Alright, I adjusted my keyTyped method to this, but the problem of focusing still persists. @Override protected void keyTyped(char typedChar, int keyCode) throws IOException { if(searchBinder.textboxKeyTyped(typedChar, keyCode)) { super.keyTyped(typedChar, keyCode); } } When I open the GUI, the text field just won't focus unless I manually set it focused in code. The vanilla code for whether it should focus (if you click on it or not) isn't working, or (more likely) is being prevented from working somehow. With the updated code, if I manually set the focus, the escape key no longer closes the GUI. the inventory key still does.

So, I'm working on GUI building for my mod and I have an issue with what will become my search bar. If I don't hard set it focused, it just won't work. Even when I set it to be able to lose and regain focus, it doesn't. Also when I do set it focused, hitting "e" closes the menu. How can I fix these two problems? Here is my GUI code (sorry it's a tad messy) The ModGuiElement is just a failed attempt at a wrapper class for all of the different ints related to a single texture (when it goes on the screen, where its located in the image file, etc).

Are there any tutorials for more advanced gui stuff? Like buttons, scrollbars, search boxes/text fields, drawing images over other images, "parsing" multiple areas of an image, etc.

@diesieben07 yeah, its only for the item that can only hold items from my mod, so that shouldn't be a problem. I just have to figure out how to take the IItemHandler and apply it to a container with searchbar, and filter and scrollwheel.. fuuuun times

So, Is there a way to have an item or tile entity with an inventory that will only be as big as it needs to be? Kind of like an ArrayList implementation? Essentially I have an item that holds different cards, and you should be able to put as many cards in it as you get. So, I have my CardData objects that represent each card you can get, so each "stack" should be the instance of the card item, the rarity, and the quantity of that type. So if you had one "card1" as a common, but two " card1" as rares, then they should be separate. I don't want to just make the inventory reeeealy big to compensate for not having a set size. Is this possible? Like I know you can create a modified version of an ItemStackHandler by extending the one forge provides, but I'm not really how to go about it if that makes sense.

So, I can't figure out how to get it to where you can shift-click items into my custom container/inventory and the code I have just voids the item(s). My mergeItemStack and transferStackInSlot methods: @Override protected boolean mergeItemStack(ItemStack sourceStack, int startIndex, int endIndex, boolean useEndIndex) { boolean success = false; int index = startIndex; if(useEndIndex) { index = endIndex - 1; } Slot targetSlot; ItemStack targetStack; if(sourceStack.isStackable()) { while(sourceStack.getCount() > 0 && (!useEndIndex && index < endIndex || useEndIndex && index >= startIndex)) { targetSlot = this.getSlot(index); targetStack = targetSlot.getStack(); if(!targetStack.isEmpty() && targetStack.getItem() == sourceStack.getItem()) { int combinedSize = targetStack.getCount() + sourceStack.getCount(); int maxTargetSize = Math.min(targetStack.getMaxStackSize(), targetSlot.getSlotStackLimit()); if(combinedSize <= maxTargetSize) { sourceStack.setCount(0); targetStack.setCount(combinedSize); targetSlot.onSlotChanged(); success = true; } else if(targetStack.getCount() < maxTargetSize) { sourceStack.shrink(maxTargetSize - targetStack.getCount()); targetStack.setCount(maxTargetSize); targetSlot.onSlotChanged(); success = true; } } if(useEndIndex) { --index; } else { ++index; } } } if(sourceStack.getCount() > 0) { if(useEndIndex) { index = endIndex - 1; } else { index = startIndex; } while(sourceStack.getCount() > 0 && (!useEndIndex && index < endIndex || useEndIndex && index >= startIndex)) { targetSlot = this.inventorySlots.get(index); targetStack = targetSlot.getStack(); if(targetStack.isEmpty() && targetSlot.isItemValid(sourceStack)) { if(sourceStack.getCount() <= targetSlot.getItemStackLimit(sourceStack)) { targetSlot.putStack(sourceStack); targetSlot.onSlotChanged(); sourceStack.setCount(0); success = true; } else { ItemStack newStack = sourceStack.copy(); newStack.setCount(targetSlot.getItemStackLimit(sourceStack)); targetSlot.putStack(newStack); targetSlot.onSlotChanged(); sourceStack.shrink(targetSlot.getItemStackLimit(sourceStack)); success = true; } } if(useEndIndex) { --index; } else { ++index; } } } return success; } @Override public ItemStack transferStackInSlot(EntityPlayer playerIn, int fromSlotIndex) { ItemStack previous = ItemStack.EMPTY; Slot fromSlot = this.inventorySlots.get(fromSlotIndex); final int CONTAINER_START = 0, CONTAINER_END = this.numSlots-1, PLAYER_INV_START = CONTAINER_END+1, PLAYER_INV_END = PLAYER_INV_START + 26, HOT_BAR_START = PLAYER_INV_END+1, HOT_BAR_END = HOT_BAR_START+8; if(fromSlot != null && fromSlot.getHasStack()) { ItemStack current = fromSlot.getStack(); previous = current.copy(); if(fromSlotIndex <= CONTAINER_END) { if(!this.mergeItemStack(current, PLAYER_INV_START, HOT_BAR_END + 1, true)) { return null; } } else { if(!this.mergeItemStack(current, CONTAINER_START, CONTAINER_END + 1, false)) { return null; } } if(current.getCount() == 0) { fromSlot.putStack(ItemStack.EMPTY); } else { fromSlot.onSlotChanged(); } if(current.getCount() == previous.getCount()) { return ItemStack.EMPTY; } fromSlot.onTake(playerIn, current); } return previous; } }

@Daeruin Thank you! I got it to work! Now, I just have to finish lining up my gui and container, lol.

@Cadiboo so, resource location is safer than just a string?

So, I noticed that there are two versions of the method GameRegistry.registerTileEntity. One takes the class and a String and the other takes the class and a ResourceLocaton, the former being depreciated. The forge documentation only mentions the latter, but I'm not sure how to convert my string to a ResourceLocation, and what resource would it be pointing to? Or does it not even matter and the ResourceLocation is used as a fancy wrapper for the string that for simpler things it doesn't make a difference but gives you the opportunity to do more with tile entities than you could previously?

@Daeruin kinda? Like I get that, but is there a "tile entity" equivalent for items? or is that what the class that implements a capability would be. If my understanding is correct, all a tile entity is, is just a wrapped capabilities type thing that is used to attach a capability to blocks and handle them being placeable and such. so I create my own interface that extends ICapability for my needs (lets say a backpack for example) then create an object that uses that custom interface to "do things" like handles writing and reading nbt to the item its attached to (the backpack in this case) then register it with forge and "attach" it to my item class, right? is that the basic idea, or am I missing something? It's really weird, you'd think that someone would have a tutorial on how to do this by now. Not that I just want to copy someone else's work, but I learn better when I have someone (or an article) walk me through it first. Yeah It's similar to making a tile entity, but it's the different parts that confuse me; the new stuff is where I struggle because I'm not great at synthesizing solutions to problems I've never encountered. A lot of Minecraft modding is like that. It's not the easiest thing to do when you get to a point where the "basics" end. That's all most ever get to, unfortunately.

@Daeruin I have. There isn't anything on creating items with inventories/data. I know its comparable to blocks, but I was hoping for *something* to show me the basic way to get something like that to work,

@Cadiboo alright

@Cadiboo I get that, but actually creating the right capabilities and such

So, I'm trying to create an item that can hold an inventory with a GUI. My problem is I can't really find a good guide on how to set it up. I know I need to use the capabilities implementation forge has, but that's about it. The forge documentation alone doesn't really give me much direction. Does anyone have a guide or a code example of creating a simple item with a GUI with an inventory?
