Unreal Engine 5 Tutorial - Inventory System Part 1: Inventory Component

[@dankelpuff8381]

For anyone wondering which youtube series to follow this is truly the one. Simple, elegant and correctly uses classes. Best tutorial i have followed so far.

[@Suleyk95]

I actually watched many series, but they're too long, or they don't explain the "why" behind everything, and I just end up copying stuff without understanding why or how it works. Just watched this first episode and this looks promising. Just 10 minutes and I understood how this will work overall.

[@Suleyk95]

Well, coming back here to say this ISN'T the series. At some point stuff isn't event replicated, and when you start working on saving, everything will break. Don't waste your time unless you don't care about replication.

[@JonathanBarrett-v3q]

@@Suleyk95 yeah i got to a later vid and wasnt working. Things not showing. Followed it to a T. Off to find another tutorial. LMK if you find one that works. Specifically for third person

[@Suleyk95]

@@JonathanBarrett-v3q I followed a few inv tutorials and to be honest this one is well organized and easy to debug/modify, the bad part is the replication and saving. My advice is to watch a detailed guide on savegame, do that part on your own, and understand replication too. I managed to save player inventories by generating a save slot for each player and storing the inventory array there. The player slot name can be made in many ways, for now I'm getting the actor display name, but make sure you get it from the server, because each client instance will give actors their own name and they will send inconsistent actor names replacing the ones it shouldn't. Basically make a server call and send it your actor reference and inventory array, and the server will get the actor from the input, get its display name, set the savegame object inventory contents to the one you got as input, and once the variable inside the savegame object is updated with the inventory contents call the save game to slot function giving it the slot name you generated. In the future you can use other stuff as the slot name, such as the steam id, etc etc. For manually placed containers it will also get the actor name and save it, but for generated containers such as lootbags you will have to make some stuff so when the level loads, it will spawn those lootbags and then they can load the inventory on the actor begin play. TLDR, follow this series to get an organized inventory functionality BUT you will have to work on your own replication and saving logic, since it's kinda broken here. Make sure you don't just copy what you're seeing, understand what and why you're doing it and even if you dump the whole thing, you'll have some new knowledge and you'll be able to make your own stuff. Get inspiration from everywhere, fit your own pieces together.

[@rubbakeys16k99]

Yep - here to agree - broken bug filled mess by the end, despite being promising for most of it. Not usable by the end.

[@kimbalboa9398]

One of the things i love with this series, is the community in the comments on each video. People giving tips when using newer versions, correcting things or suggestions for fixes.. Truly awesome crowd. Ryan is superb at delievering the tutorial, giving information a long the way for us beginners. Thanks a lot mate, really helping us out

[@khalafle]

Hey, Ryan! I am still under a week old in Unreal Engine experience, and one thing I have learned while scouring KZbin for tutorials is to make sure the teachers systems are applicable throughout the entire development process. I wasn't sure if your series was for me, so before anything I watched the first (this) tutorial as it was short enough to recollect at the end. I watched two more videos, up to the end of the third tutorial, and declared that this series is the way to a proper functioning inventory and interaction systems. Thank you for the precision, feedback, and directional insight along the way! Will comment when I am through the entire series! I hope to follow along any more applicable tutorials/series of yours as you clearly understand how, let alone Unreal Engine, video games and their varying systems function. Again, thank you, sir!

[@biggalaxybrian]

Yes! Inventory Systems are hard because there are so many different possibilities and someone without the knowledge will find it hard to add to them

[@22hoursago]

thank you i knoew it :')

[@xynjak]

thank god my uni course is making us make one without teaching us the engine first!

[@qodeshgraphics]

Hi Ryan, Thank you so much for this tutorial series. I've learned quite a lot from you, and this inventory system with its related functions are going to be a key component in our game: "Antediluvian: Seed in Peril." I wish I could give more, and I probably will if the game is a success. But for now, here is a small thank you.

[@PureRealityGamesStudio]

Hey Ryan, congrats for your series. I would like to suggest you a series of how to create a "Tetris Inventory Style", similar to the game Escape from Tarkov, specially how to implement the Inventory component on backpack, armors, etc. Most part of the tutorials on youtube are old or not well optimized/simplified. I´m pretty sure you would do a better job and people would love it.

[@michaeleber4752]

Great job Ryan. Joining your group very soon. One thing I find that inventory systems need is a very good ordering system. So I've added Item Type. That way if I have iron and copper both are of type ore I can sort by type then name. All of my ores are together then alphabetized. All of my materials are together then alphabetized. etc.

[@GaladorLP]

i'm trying to follow along. At 3:50 in the struct. If i wanted a weight based inventory size woul i need to ad another variable thats a float? and of course make inventory size a float. somthen i can fill inventory size with weight times quantity, right?

[@OLucasQueJoga]

So far very clear and easy to follow! Thank you!

[@waadi3ach569]

this is the go to inventory series in my opinion, very modular and organized and easy to customize for specific use. great job! in my specific case the inventory moves up and down with the character similar to ALS, and Game and UI and has a built in equipping system.

[@nacargod5110]

hey man i followed this tutorial and made an inventory system but i'm really struggling with making an equipment system working together with the inventory system i made following this series. u got any tips?

[@brianstrigel2241]

Thank you so much for this series, as always!

[@moo_goo]

Please update the playlist for othrs, I had to go search from episodes 18-22. Great stuff! hope youll add splitting, and how to get this working for PC and console in the sense that controllers dont have mice and it would be better to have the cursor snap to each grid item. Thanks!

[@AnarchyArtwork]

I followed this series in Unreal 5.3 and it works brilliantly. I did have to make the appropriate changes for the new Enhanced Input Actions when setting up inputs. I'm completely new to Unreal though and Ryan even has a video about setting up those controls so you can use that video to guide the differences. I've even been customising this system a little as I experiment further. Good luck everyone and stick with it, thank you Ryan! 🐐⭐

[@rubbakeys16k99]

DO NOT follow these tutorials or "stick with it" - anyone saying they're brilliant or even fully work has not tested them properly. They are a broken, bug filled mess by the end and remain unfixed

[@AnarchyArtwork]

@@rubbakeys16k99 Could you explain? It works perfectly in my packaged build.

[@kameenavery9616]

if possible, can you do both a single slot inventory and a grid based inventory? I was thinking it would be cool to let the player decide their inventory type, or have a single slot inventory on the player and a grid slot for the containers

[@mijake9001]

Check out Jonatan Isaksson. He is in the middle of doing a very useful guide of Inventory system/equip system. Good content, videos aren't structured as well as Ryan's videos but sounds like it might be what you're looking for? Not to advertise him and poach traffic; just trying to help everyone out. :)

[@LeahsRoomYT]

Hi Ryan! I don't know if it's mentioned later in the series but I'm trying to take notes as I go and I was wondering why you add the "F" prefix to your blueprints? Is it just for referencing or does this make an actual difference later on? Thanks!

[@megtwin]

I was wondering the same but for my Structs I always prefix them with an "S", its just easier for me to find them.

[@LittleBlue42]

That texture 2d in the item struct should be a soft reference. If you reference a data table which is full of hard references, it will load all the references contained in it. Using a soft reference lets you async load the asset afterwards, and wont load all the textures listed in the data table at once.

[@chomnansaedan4788]

You know. If I can't find a job using UE I might start trying to learn things others don't and making youtube videos about it. Its not only very helpful to upcoming people but it can maybe serve as some income for myself. Thanks for these series.

[@goatlcknguud2595]

how is this going bro?

[@etchasketch222]

Developer beware: This tutorial has some bugs within, especially after the 18th video. You'll have widget focus issues, inventory items will stack and double when they're not supposed to and he finishes with a menu filter system that doesn't work as intended. It's still good for learning some things, but it's not going to get you a proper functioning inventory system that's bug free. He also starts the tutorial being for multiplayer then kind of gives up on it mid way through. Some client and host issues within. I like what you do Ryan and have been helpful, but you have to make sure these tutorials are iron clad. Folks spend precious time going through them, often pausing or watching at slower rates only to get to later videos and things start falling apart. If you could release a updated, bug free fix video (even though it's been a year and you haven't), that would be great.

[@nacargod5110]

hey Ryan is there any chance that you show how to build an equipment system working with this inventory system?

[@MichaelLindsey]

I noticed that there is a Snag at the point where you create Functions, for me the Video hangs at Addto and doesn't continue until you are adding the Integar to Inventory size

[@heikesteinheim9337]

tru, have u found out, if he does sth important there? still wondering how nobody noticed, this happens quite a lot

[@KeiNovak]

At around 2:11, right? I was wondering why none of the top comments mentioned this. Wasted like 15 minutes trying to figure out if it is an issue on my end or not. Sometimes it happens because I watch videos at increased speeds most of the time haha

[@SamuTheFrog]

I'm curious why you don't do these with C++? Something like an inventory system I would think would greatly benefit the performance boost of using straight C++, and having someone build a whole inventory system in BP for their game seems like shooting themself in the foot in the long run.

[@rubbakeys16k99]

Because the system you will build in BP is broken enough by the end of the tutorials, so why bother with C++ on top??

[@AtakenSmith]

A well optimized BP system is good enough to not bother with coding it yourself. Don't forget that BPs are just codes as well in the end.

[@PaulV3D]

Great tutorial. Think I will join patron.

[@jamiedoyle5101]

Great tutorial. but would like an inventory system that adds individual items instead of item types. eg if you have a torch that is 50% used, if you add it to inventory and take it back out you get a default torch from the data table and not the partially used one. Can anyone point me to a tutorial that could get me started.

Hi, this will work for ue4?

[@Nicara_V]

Please specify that this tutorial is for 5.0 as recorded. When you use 5.1 or higher, and unless you fully understand what to change to use the new Enhanced Input Actions you can break the game. I started using 5.3 and am currently on part 7, I ran into extensive issues, everything worked but i lost all camera control upon closing the inventory..sadly I don't fully understand what to change to make it work as I'm fairly new to the character programming side of UE. Sadly, I won't be restarting this tutorial to downgrade my project to 5.0

[@joshuawolford5808]

I am using 5.3 and it works perfect.

It's a great base line tho for those who already have a 10-30 hours of knowledge. So unless you know what functions, components, blueprints are don't go in this rabbit hole. Everyone else go for it, it's a great training to test your debugging skills.

This guy makes videos shorter and shorter... i hope he will not start doing series with 1min video length, with 100 parts, with 1 video per week. obviously he is getting greedy and forcing people to pay on patreon.

[@smelge]

Oh no, someone might need to earn money on work they do. What a terrible thought. Or, instead of being a whiny tool, maybe shorter videos work better because there's less to debug when the viewer has to go back if they made a mistake. It's easier to roll back and repeat a 10min tutorial section than a 3hr one when what you have doesn't match what he has at the end of the video. Or maybe it makes sense to confine the building of each component to a single video.

[@eligijuspranskunas3509]

the thing is that i'm paying and apreaceate his work great tutorials, but to pay for tutorials when you have to wait a week just to see one video, in which one shows just how to create actor component and add few variables and video finished... it makes me feel like - i'm supporting him, and just to see few minutes and then wait again, wtf... it's just my own opinion.

Having certain suit gives more inventory slots etc, but I think My brain can manage it if I get basics down and memorised at some point.

[@darnunt]

We need to keep in mind that video game developing courses are pretty costly. They can easily range between 7,000 - 40,000 dollars, depending on the institution organizing them. Even if you are a Diamond tier patron (paying 50$ / month) that's still nothing compared to what you'd have to pay for an "official" learning course. Not to mention all the videos that he uploaded for FREE. I think people should be a little more grateful that amazing devs like Ryan are willing to put the time and effort into things that are either very cheap to access or absolutely free. I wouldn't have gotten far at all without Ryan or CodeLikeMe giving us all these amazing videos from which we can learn. Because I doubt I could ever afford even the cheapest course out there. The internet truly is a blessing, and these people even more so.
