For those that have issues moving the item when the count is higher than 1. In the InventoryItem class, OnBeginDrag turn off the raycastTarget for the Count Text ex. CountText.raycastTarget = false or turn it off in the Prefab Also turn it back on in the OnEndDrag function ex. CountText.raycastTarget = true
Honestly incredible, I had not found a tutorial so simple, effective and that goes directly to the point, full of examples, with a minimalist edition and perfect for the understanding of anyone who sees this video. simply incredible, my congratulations.
This was an excellent tutorial! A great starting point for an inventory system. There's definitely a couple other things I'd like to add to this system but I really appreciated just how thorough and succinct it was for a relatively more complex system. Thank you for making this!
Here's a quick tip I learned that saves some time. Instead of locking the inspector you can hit the three dots in the inspector for which area you want to keep open and select "Properties". This opens up a floating window with that area for which you can freely drag and drop :) Saves you the time of having to Unlock and you can also have multiple floating windows open.
This tutorial taught us a lot of new things and helped us establish the groundwork for our project, there were some frustrating moments where something didnt work but usually reviewing the code and/or the video held the answer to the problem, thank you!
Hello, I love the tutorial, very easy and useful, I would like to share this technique that I used to select the items with the scroll wheel of the mouse... float scroll = Input.GetAxis("Mouse ScrollWheel"); if (scroll != 0) // Seleccion con el scroll. { int newValue = selectedSlot + (int)(scroll / Mathf.Abs(scroll)); if (newValue < 0) { newValue = inventorySlots.Length - 1; } else if (newValue >= inventorySlots.Length) { newValue = 0; } ChangeSelectedSlot(newValue); } One other thing, if you are using TMPro to display the number of items, you need to disable the Raycast Target option which is active by default in the component, otherwise the stackable items cannot be dragged to another slot... hope I helped.
Hey, first of all thank you for this! But I have a problem, when I am scrolling selected slot changes, but it stops after reaching the last slot it does not go to the first slot like Minecraft slot selection, do you have a solution?
@@fryptompt I think you're copying the code snippet wrong, or maybe it's something else from your slot arrangement or also check your selection method.
@@fryptompt I was having the same issue. When going through the scroll is was scrolling through items in the invetory page too. To fix this, change the return at the bottom to ChangeSelectedSlot(newValue % [NUMBER OF TOOLBAR SLOTS + 1]). My tool bar has 8 slots so I set it ChangeSelectedSlot(newValue % 9) and that fixed it.
such a tutorial for the UI toolkit would be amazing! you always explain everything so well, and there are so few tutorials for the toolkit, this would help a lot!
Thanks! It was a difficult video to pull off, because of its complexity, but hopefully everyone will be able to follow along with all infographics and explanations along the way 👨💻
Great vid btw. Would be nice if we can combine and split stacks 2. a tip for the rest to make it even more performant. put an if statement before the loop checking if its stackable or not instead of checking it for every slot and then doing the empty check loop.
You Can Combine Them By Changing Your OnEndDrag() function To This public void OnEndDrag(PointerEventData Data) { Image.raycastTarget = true; InventoryItem InvItem = Data.pointerEnter.GetComponent(); if(InvItem && Item == InvItem.Item) { InvItem.Count += Count; InvItem.RefreshCount(); Destroy(gameObject); } else { transform.SetParent(ParentAfterDrag); } } I'm not sure how to split stack tho
Thank you soo much for this tutorial !!! It helped me to understand crucial fundamentals of inventory management. It also kick-started coding future futures on my own. I added merging items and scrolling through ability. If anyone out there would be interested i can share the code.
Pretty Good video, You explain mostt stuff pretty well. I ran into some issues when I tried to sort the inventory. Particularly with Destroying a inventoryitem and then in the same function checking if it is null. This is because the Destroy does not happen until the next Update. Also including some features or direction for how to make the inventory controller accesable would be good. Overall great tutorial!!!
This is one of the cleanest inventory tutorials i've come across here on youtube. Great job! Subscribed. How would you go about dropping an item out of the inventory bounds to remove it from the inventory entirely?
I found a way.. rather clumsy, but works for now. public void OnEndDrag(PointerEventData eventData) { if(eventData.pointerEnter == null) { // outside of inventory } }
Good guide, but I'd like to know how you can make the discarding of items when releasing the cursor outside the inventory (the selected item should be removed from the inventory box and appear under the player or in the place where the cursor was released) Also need the reverse logic of picking up items, so that the lying item can be picked up in the inventory box P.S.: I'm developing a top-down game like Dont Starve.
Hey, so i'm making a 3d survival game and I was wondering how would I be able to make it where you see what your using/holding Excellent content btw, explained everything so nicely!
How do you stretch with rectangle tool symmetrically? I try shift and it's only doing uniform scale. Great video, thanks! PS. It is pressing and holding Alt after the start of the dragging.
Hey! Great tutorial :) But one thing bothers me.. How can I replace items on drag'n'drop in the system you've showed in the video? I mean, drop a pickaxe in the place of the shovel, and they will swap. Would love to see some tips!
If someone else would look for solution - I got it to work. We need to add another condition in "InventorySlot" script. if (transform.childCount == 1) { InventoryItem inventoryItem = eventData.pointerDrag.GetComponent(); InventoryItem oldItem = transform.GetComponentInChildren(); oldItem.transform.SetParent(inventoryItem.oldParent); inventoryItem.parentAfterDrag = transform; } Also, we need to define public Transform oldParent in "InventoryItem" script and set it up in the same place where parentAfterDrag is set. And that's all, it works!
any one have the same problem? around 11:00; when i try to initialize item; in unity; In unity no image can load and it keep saying NullReferenceException: Object reference not set to an instance of an object
why am i getting the error Assets\InventorySlot.cs(13,78): error CS0246: The type or namespace name 'InventoryItem' could not be found (are you missing a using directive or an assembly reference?)
My inventory item kept disappearing while being dragged. In case anyone has this problem, I finally figured out that for me it was because my Canvas was not at the root level of the scene.
Could you please explain what that means. I am having the same problem and my canvas is apart of a player that is instantiated at the start of the game.
@@connorwilson-long1336 Make sure your Canvas object in the scene manager is at the top level. If you have it nested under a game object (like an empty game object called 'UI', or the 'Player' game object for example) then it won't work.
Awesome Tutorial. I have one problem tho. I can only drag Items with the count of one in other inventoryslots. Anything higher is still draggable but will return in it's original slot. Any idea why? I checked all the code multiple times now :(
Hi Very Great tutorial thanks. can you make a tutorial on how to blur UI button without changing the canvas from screen space overlay to screen space camera? Thanks again for such a great tutorial! 🤩🤩🤩
Really awesome tutorial! Is there any chance you would expand on that? such as showing a selected Item/weapon on a character and decreasing the correct ammunition for it (arrows, bullets etc.) when stored in a different slot?
this tutorial is beyond stellar. its not only easy to follow but also most solutions are super elegantly implemented. i only had a single issue. ater i added stacking items with a stack where not able to be dropped into another slot anymore. any idea what might be causing this?
As always... asking the question instantly helped me to find the solution... newer Unity Versions don't support regular Text anymore and thus you have to use Text Mesh Pro. Text Mesh Pro however is by default a raycast target and you have to open the advanced settings and disable it so your Count Text does not Catch the Drop Event
Hello, I found a problem, either I missed something or it's gone passed without noticing but if I got a stackable item that only got a count of 1 I am able to move it between slot, but as soon as I got 2 or more counts of it in a slot I can't move it anymore between slots.
Do you have a connected tutorial to save the inventory between game sessions? I thought scriptable objects couldn't be serialized (and thus saved) in unity, which is why I'm confused
I wanted to add a child object to inventroySlot prefab But when I did, after adding inventoryItem, everything in inventorySlot messed up. how can I have multiple child (i.e. a ribbon around the selected slot) for that ?
i found a bug and would love it if u do a small soultion for it if you drag item while the inventury full and there is a item on the Ground, the item will take the place and u left up with a full Inventury with no place for the Dragged Item
i have fixed mine by adding boolean in inventoryItem and PickupItem called it isDraggingItem turn it on if on Begin drag and turn it off in End Drag then i use if statment in InventoryManager add item funcation , by doing if (!isDraggingItem) { all add part below } return false; ,, long story short can be fixed if you use boolean.
Im having a bug where when you select the first slot it doesnt show any slot being selected, but when you select any other slot it and the first slot are selected.
Ok now how do I make another Object Active, when it is selected? Like I have a Script, and in this script I want to say: If(SelectedItem = Axe){Make Axe Active} else{disable axe} or something like this. How would I do that?
Thank you so much for the tutorial ^_^ Is there anyway to make it so only a specific ItemType can go on a certain slot ItemSlot? How would i go about doing that and which scripts would i need to change? Thanks!
When I make the inventory a child of my player character prefab (I have a multiplayer game) the items disappear when dragging (but everything else works fine). What changes would I need to make to the code?
@@FlizzyGlizzy there are 2 kind of issues you are meeting, if it's teleported in the middle of nowhere (you can check it by selecting and drag to check it's pros x,y), or it legit "dissapear" behind the other UI for the teleporting: it because of the canvas render mode you are using is world space, you need to change it to screen space - overlay and resize it by using canvas scaler. for the "dissapearing" behind the other UI, it's possible that your canvas isn't at the root level of the scene hierarchy (example: you are creating a canvas inside an empty object, so when you drag, the canvas no longer detect the item as its children anymore [i maybe wrong but that's what i solved])
there’s a problem with item stacking for mine, ive narrowed it down to my code can’t detect if the item in slot is equal to the item your getting and i can’t figure out why
im a total beginner with unity/ scriptig etc.. i tried to figure for an hour how you where able to fit the image of the InventoryItem into the Image, turns out its the gameobject thats needs to be there maybe i should have watched the other vid first nice tutorial tho
I have a problem, I want to make that when I select an Item, a script read his id and depend of the object it active a weapon. Well my code is "if(item.itemId == 1) --> gun.SetActive(true)" but when I select an empty slot, the game crash because there ids not any item to read his id and I don't know how to fix it
Maybe learn more about Dictionaries? You could set your item ID's in a dictionary and change them around. I think the computer has trouble figuring out what is the actual item in the slot when it comes to ScriptableObjects. Not sure though
That's one big tutorial for me to my game, yet I have one question....How can the item be undraggable once it is dropped? I really wish that's in that tutorial, I can't find any other...
Okay so here is my scenario. When raycasting a tagged "pickupable" && player presses E, I want to be able to destroy game object and then add it to my inventory. I have this functionality on a seperate Pickupsystem script. How would I go about doing this? I you all need more info let me know.
How to fix this error So basically I made a little script where I can drop items And pick them up When I drop the item I can keep dropping the item by the item is out of my inventory The Duping them I don't know way to refresh the inventory when I drop an item Here is the code that I wrote public Item DestroyItemInSlot() { InventorySlot slot3 = inventorySlots[15]; InventoryItem itemInSlot3 = slot3.GetComponentInChildren(); if (itemInSlot3 != null) { Destroy(itemInSlot3.gameObject); } return null; }
Everything works until I try to click that spawn item button, It spawns my items downward instead of horizontal to the right.. I saw that the all clones get parented to the first inventory slot, but why?
Bit late but I checked and I had "GetComponent" and then edited and tried "GetComponentInChildren" and it worked. I think I didn't watch the video enough closely. But thanks for noticing that and now I got mine work!
The video system looks great, too bad it didn't work. The asset could be free, right, because it's been years and apparently certain things aren't working even though they're exactly the same. I'd like to at least have the asset to test if it's some extension that's causing the issue or something like that

For those that have issues moving the item when the count is higher than 1.
In the InventoryItem class, OnBeginDrag turn off the raycastTarget for the Count Text
ex. CountText.raycastTarget = false or turn it off in the Prefab
Also turn it back on in the OnEndDrag function
ex. CountText.raycastTarget = true

I have a question, i am implementing this into my mobile project but i dont know how i can get the selected slot from buttons, thanks in advance.
How would I implement an amount in the AddItem(item, amount) ? I am making a loot script and want to add more than one of the same object.
I have a problem, I want to make that when I select an Item, a script read his id and depend of the object it active a weapon. Well my code is "if(item.itemId == 1) --> gun.SetActive(true)" but when I select an empty slot, the game crash because there ids not any item to read his id and I don't know how to fix it
Maybe learn more about Dictionaries? You could set your item ID's in a dictionary and change them around.
I think the computer has trouble figuring out what is the actual item in the slot when it comes to ScriptableObjects. Not sure though
@@DemersCreations ok thanks
Love this total Id suggest watching it over a few times to fully grasp the concept. also dose anyone know were this guys form I like the accent!
That's one big tutorial for me to my game, yet I have one question....How can the item be undraggable once it is dropped? I really wish that's in that tutorial, I can't find any other...
That's a quite custom request for such system. You should be able to achieve that by setting in OnEndDrag: image.raycastTarget to false (6:17)
@@CocoCode Yes HAHA, it worked...Thank You very much
How can I lift an object from, for example, the ground ? With the help of this great tutorial :)
That is covered at the end of this video when we merge projects with Tamara :)
Guys If there is an item in the inventory that is not in the selected slot, I want it to be deleted. Can you help me
Hi, Can you make a second video where you explain and teach us how to make a GameManager for this inventory ? to change scene with it
thank u
Okay so here is my scenario. When raycasting a tagged "pickupable" && player presses E, I want to be able to destroy game object and then add it to my inventory. I have this functionality on a seperate Pickupsystem script. How would I go about doing this? I you all need more info let me know.
I'm struggling to translate this into a photon multiplayer inventory system :( Does anyone know a good tutorial or way to do it online?
How to fix this error So basically I made a little script where I can drop items And pick them up When I drop the item I can keep dropping the item by the item is out of my inventory The Duping them I don't know way to refresh the inventory when I drop an item
Here is the code that I wrote
public Item DestroyItemInSlot() {
InventorySlot slot3 = inventorySlots[15];
InventoryItem itemInSlot3 = slot3.GetComponentInChildren();
if (itemInSlot3 != null) {
Destroy(itemInSlot3.gameObject);
}
return null;
}
Everything works until I try to click that spawn item button, It spawns my items downward instead of horizontal to the right.. I saw that the all clones get parented to the first inventory slot, but why?
in the "InventoryManager" script, you put "GetComponent" instead of "GetComponentInChildren"
Bit late but I checked and I had "GetComponent" and then edited and tried "GetComponentInChildren" and it worked. I think I didn't watch the video enough closely. But thanks for noticing that and now I got mine work!
man, thats what i want
The video system looks great, too bad it didn't work. The asset could be free, right, because it's been years and apparently certain things aren't working even though they're exactly the same. I'd like to at least have the asset to test if it's some extension that's causing the issue or something like that
has anyone implemented splitting stacks at all? Curious to see how people achieved that
