Godot 4 - RPG Inventory System From Scratch

[@PeterGilesKnows]

This is the best godot tutorial I have encountered so far. Aside from being practical implementation of an inventory system, there's just so much incidental stuff about how to navigate the interface, signaling, singletons, project organisation as code evolves, and all kinds of little extras that I haven't seen in so many other tutorials. Massively useful.

[@DevLogLogan]

Thanks for watching! And that's exactly why I make videos like this, always glad to see someone resonate with the format. :)

[@PeterGilesKnows]

@@DevLogLogan it really did, I followed the entire tutorial pausing it, mimicking your actions and am way more confident with navigating in Godot. I have an ambition to build a tactical RPG engine like XCOM or like Solasta. And this style really helps me understand that while I am leagues away from doing it, it’s possible

[@buckets3628]

@@DevLogLogan I too appreciate this video for the same reasons, amazing job look forward to learning more.

[@tomargamedev]

I'm glad Godot is used by people like you, you have great tutorials

[@Haxses.]

Awesome tutorial. One suggestion I have for future videos is to enable the script list sidebar for the tutorials (the one that shows up only while in script mode). I need to go back and rewatch sections of the video frequently and it's difficult to tell at a glance which script you are currently editing. It would really help a lot to have that info on screen rather than having to back track and try to watch which script you click on/search, and then fastforward to where I was.

[@GaryParkin]

Yes please.

[@ThecrystalwizardCoUk]

Yes please! I found this video VERY useful, but had to keep going back and forth to double-check my code, and having some Visual Clue as to which Script you were working on would have been a great boon!

[@RonaldFinger]

Can't say I understood even half of what was going on, but it was fascinating nonetheless! I just picked up Godot for the first time last week, which is apparently right when version 4 came out. There's been almost no tutorials covering the updated software, except for yours! And they're so well done! Thanks so much for all you do.

[@lethn2929]

Inventories are pretty advanced even by experienced programmer standards and they can get extremely advanced when dealing with huge item databases Skyrim style among other things that you need to keep track of. As with anything, start off small and easy, you don't have to code a whole inventory from scratch, you could familiarise yourself with a simple hotbar and you can still do a lot with that in games if you get creative. By the way! This is something I'm trying to encourage people to experiment with, but you don't necessarily have to setup an entire grid to do an inventory, you should research how to do lists, they're often easier to code and setup than the grid based inventory systems.

[@catcactus1234]

@@lethn2929True, especially since this tutorial is clearly not aimed towards beginners with how fast paced it is (not saying it’s a bad thing). Definitely a good tutorial to return to when they feel more comfortable with Godot though. I’ve sat through a lot of inventory tutorials on YT and none of them have been as efficient and clean as this one.

[@marceloamaral1507]

@@lethn2929 Thanks for the encouragement, seeing an inventory system like this makes me think it would take me at least a few weeks of hard study to actually know how to do this without a reference project. There are so many moving parts all talking to each other at different times... This seems like playing the piano, the level of dexterity here sure wasn't acquired overnight. It is impressive but at the same time for an aspiring game designer it can be overwhelming... I'll try my luck with lists and simple inventories before attempting to copy and modify something like this.

[@Schwilliam]

You are a legend, I'm off to a great start in Godot thanks to your tutorials. Keep 'em coming 🙌

[@leolambert3605]

The greatest KZbin tutorial I have ever seen. Insane

[@lordhuebi]

I've been going crazy trying to put together an inventory and item system from different tutorials over the past few days. This video ia a godsend! And I love that you use Resources.

[@DevLogLogan]

Making a resource based system like this has something I've wanted to try for a while now. There's so much I wish I could add and explain further but I hope you're able to benefit from my setup here. :)

[@lordhuebi]

@@DevLogLogan Hey, nobody is stopping you from making a follow up video ;)

[@catcactus1234]

@@DevLogLoganI’d also love a follow up video with the other features you wanted to add! Going over saving and loading for a system like this would be a godsend. :)

[@Snafuey]

Your a gem of a teacher due to the great design, programming, and Godot skills you possess . Please keep making tutorials!

[@Cablesfish]

Love your tutorial! I'm learning SO much! Just a request for future videos: Please include the list of scripts in the sidebar of your script editor. I'm sure it's prettier without it but it makes it harder to follow along with what script you're in. And please keep up the good work!

[@baboonaiih]

13:45 - When you dragged the item grid into the code and it preloaded the path with a variable name for you I actually gasped, "wow" out loud. I know it's simple but that's the kind of editor behaviour that really makes this thing accessible. Amazing

[@borob.5168]

I like that you're doing stuff from scratch, which is the best way to learn for newbies like me. Thanks for your work!

[@SideQuest_Obsessed]

This tutorial helped get me started with godot, and i'm loving this new hobby. Thank you a million times over for this! I changed the hotbar to be its own standalone inventory to better suit what I'm trying to accomplish, and it worked out once I flowcharted how data moves around this structure. Next on my list: adjust the merge so that it tops out a stack that is close to full and either leaves the leftovers in the held slot or creates a new stack / stacks with the leftovers.

[@twist56]

I've been loving how more Godot 4 tutorials are popping up and this is definitely one of the best ones! Great job on this!

How did you made this part of the tutorial because its just not working. Version of Godot 4.1.1

[@synapse84]

Perfect timing on this, I just started work on creating my inventory last night. Many thanks.

[@aomadeira]

This video has a massive amount of high quality content, not only regarding inventory system, but Godot in general, this is pretty much a "Godot 4 Crash Course"! Hats off to YOU for pulling out a huge contribution like this to the Godot community. 👏👏

[@_NISHI]

Thanks man, you really helped me. I couldn't for the life of me get an inventory system to work well. This video is absolute gold.

[@MrRAH6889]

had to get through this 10 min at a time at first but then i was able to zoom through the second half. thanks alot for this man!

[@willigoen]

Yesterday I just Can't believe the ease to handle that bunch of information in such a fast pace way, man it has to be so cool have those super powers! Great tutorial, blessed with such a great content creators like you!

[@lufog]

A more flexible solution is to create a stack_size variable in ItemData and remove the stackable variable altogether. There will be no point in it, because you can just set stack_size = 1. And in ItemData you can add the is_stackable() -> bool method, which will return stack_size > 1. So each type of item can determine its own stack size, one for seeds, another for food or potions, and so on. Also, instead of SlotData, I would call the struct StackData or ItemGroupData, because slot is closer to ui than model data.

[@arthurlevannier550]

Honestly I nearly never comment videos on KZbin but man all your tutorial on Godot are incredible, straightforward explicative enough and all the small tips you give are really useful. Thank you so much hope to see more of your content

[@AprilGhost]

Finished the tutorial in full, AMAZING wealth of info, thank you so much! I'll be spending a lot of time going through and trying to understand more of what just happened, but it's not because you didn't explain it well, there's just so much information packed into this and even understanding 10% of it makes me feel so much better using godot.

[@jSnakeChips]

I feel that. I dont know how many times I paused it just to even try to keep up let alone try to understand what he was doing.

[@Cafeinrush]

Really loving this tutorial, was searching for a proper one. Even wanted to order a survival course on Udemy for it.. But glad I found this.

[@ItsJustMJ3]

KUDOS for such a complete, feature full and functional GODOT inventory tutorial! My 3D project is less RPG and more explorative adventure but it needed a good inventory system non-the less. It even taught me more about GODOT resources and how to use them properly. Really appreciate everything you've done here. TYSM!

[@charliemossop4057]

Honestly one of the best tutorials for godot4, so clear and only using best practices

[@fkeyzuwu]

hands down one of the best tutorials ive seen for intermediate godot devs, super clean code and very easy to understand.

[@lethn2929]

As others have already posted, seriously, keep up the good work, this channel is one of the most coherent and organised I've come across. I think that given how much Godot 4 has changed everything the new and improved engine really does need it's own channels because it can get frustrating sometimes having to re-write and debug code because syntax has changed and new nodes have been added that make things an almost one click process.

[@benjaminnewington9099]

Love how thorough these are

[@Simon-ik1kb]

I was really considering quitting Godot... But now watching your tutorial made me get back to learning Godot. This is exactly what I needed for my small project. I hope you will continue making these videos. Thank you.

[@felixp535]

This is actually an amazing tutorial for Unity users switching to Godot. From what I've seen, Resources behave basically lile ScriptableObjects, signals like events, and even the UI system is quite similar (I'd say it's even better in Godot!). Even though I don't actually need an inventory in my game, just seeing how an experienced Godot developer does things helps tremendously understanding the engine. Thanks a lot! Amazing work!

[@ktc50222]

You do a great job explaining everything especially what buttons you press when you use shortcuts and subtle things. Learned a lot, thanks a bunch!

[@dardasaba7971]

Amazing tutorial, a super helpful topic and it gets to the point quickly!

[@bushmonkey78]

A bit late to the party but i just wanted to say this tutorial helped me a ton. The only criticism i have is that I don’t like that the inventory interface and the player have to know each other. I changed that instead to having a global getter/setter for the inventory data and on “change”, emit an ‘inventory_changed” signal that the inventory interface would listen to and update its own reference. My way also has the advantage that @23:39 you don’t need to do all that signal connection crossing the streams between your data interface and the UI

[@kerplunkyo]

This is really well done! I just started with Godot and this tutorial was super helpful, thank you! I think I will change the equip inventory even a bit more so that you can only put specific item types into slots. Let's say there are slots for helmet, chest and boots armor... and you can't put an helmet into chest slot. Thanks to your tutorial I think I know how to do it. Thanks again!

I'm fairly new to Godot so not a big fan of the Miziziziz-style "hurry up and copy me" tutorial. (I don't retain the info that way) However, I did manage to figure it out in the end so thanks!

[@scantinstance5256]

I actually think he did a great job with the pacing of this video. Im also veryvery new to coding, and i understand that a detailed description of how the code works would be nice but i dont think that thats the main target audience. I mean in this video hes teaching us about how to create an inventory, not how resources (for example) work. That said, i still appreciate how much this applicative demonstration can teach one about the intricacy of combining code.. for me this is much more effective than watching videos about certain topics without getting realtime examples.

[@StaredownGames]

@@scantinstance5256 well said! I think a big part of my issue is I have poor vision and it can be very hard to keep up with people. I did learn a lot from it but definitely had to watch a few times. lol

Im a year late for the party but I finally was able to finish this tutorial. This is one of the rare godot finds, I learned so much and especially the resource based working will be handy in the future. Tank you so much for sharing your knowledge! Tips for finishing for people that are as bad as coding as I am: #1 slow the video down, I was able to follow it comfortably at half the speed and it made a huge difference #2 set up github, I dont think I would have finished it without as I somehow keep breaking projects

[@stephankjaerjepsen5459]

Very good! It was long but as I get to the end I just wanted more! Thank you for taking the time make it.

[@scantinstance5256]

Wow. I love the dedication here. Haven’t learned as much from any other tutorial. Even though your explanations aren’t exactly beginner-friendly, it gives a lot of insight when what you’re learning immediately transforms into an example. I would really love to see videos from you where you just show all the little nooks and cranny’s, you know about certain „Methods“ (idk things like resources or signals.), can be applied. Some parts of this video just felt like magic. There where lines where i couldn’t believe, it didn’t print any errors… Thank you for this massivly helpful video!!!

Maybe a video about Saving combined with this inventory interface. So that its easy to understand how you can expand on an intrigued system.

[@360greenboy]

Just something I learned while incorporating this into my game, when you instantiate new slot scenes EVERY time you want to update your inventory you are creating A lot of unnecessary frame time lag, if you simply hide the slot quantity and nullify the texture instead of creating a whole new itemgrid every time you can increase performance.

[@JFran.]

I noticed it too, everytime i interact with the inventory, they are deleting and adding slot childs. Could you help me in how to hide the slots?

[@darkbiquette6664]

Very nice video thanks a lot ! It could be very interesting to have a video with the other option to create a equip inventory by creating dedicated slot instead of reusing the inventory data. Because most of games don't put the equipment slot in a grid but around a character picture and here the whole system seems to be build around the concept of having a grid container.
