How to Create a INVENTORY in Godot 4 (step by step)

This video is a step by step process to creating an excellent well working inventory system in Godot 4, I spent a long time trying to figure out the best way to create the most functional and efficient inventory system in Godot, and after a lot of research I’ve decide this is the best possible way in my opinion so I wanted to share and make a tutorial on the step by step process of how to create it and wanted to teach you how to implement this inventory system for your own Godot game.

Perfect. This is EXACTLY what I needed, step by step, no bloat.

[@dev-worm]

so happy to hear! thanks!

[@origenydestino13]

Yet again you cover something very "basic" for a functional game and you provide with tools to create a quick inventory system that feels so satisfying to test in your own project. I will also admit one thing, which is the fact that even your mistakes were important because they helped me search and identify the mistakes myself, which helps improving your understanding of the code. Again thanks a lot for all this, really appreciated!

[@dev-worm]

thank you so much for that! I am so glad everything came out perfect and was able to help you understand and learn! searching for the mistakes is so important but so annoying at the same time lol!! thanks! and if you ever need anything at all then please let me know!

[@iky1157]

video quality stunned me into commenting. incredibly clean and concise. you knew what we wanted when we searched for a tutorial like this and delivered perfectly. not much like this around these days, keep it up

[@GenTink]

Your tutorials make everything so simple and straight forward, which is exactly what I need when I'm starting out. Maybe there are "better" ways to do things, but if I can't understand why it's better I'm not learning, so this is perfect.

[@zoeandrews7422]

Hey there! I’ve been watching your videos for a while now. You’re a REALLY great teacher and deserve so much more subscribers. I also really appreciate when you make little mistakes or hiccups. Sometimes with new devs, we don’t know that it’s okay to make mistakes or how to debug, so seeing you make little mistakes and work towards solving it is really helpful and wholesome to see. Really much looking forward to more videos. Hope you’re not overworking yourself, just wanna say I genuinely appreciate your channel and work

[@drewalmonds6219]

The Inventory System Part 1 video works perfectly well for Godot 4.2 So far, the one and only video that I was having problems with was episode 1 for setting up the walking system for walking in all 8 directions.

[@dev-worm]

[@Mordkaleb]

Great tutorial! You spoke a little bit quickly. I was able to follow you, but the video felt a little rushed as a result. Everything else was great! There was a clear through-line for the tutorial, and I liked seeing the errors, as that's how regular programming goes, you never get it perfect the first time. Very helpful for my own project, thanks!

[@dev-worm]

so glad to hear!! I am sorry it was a but quick! I will take that into consideration for future tutorials!

[@antscologne2962]

As you already have a local variable like "is_open", you don't need further functions for opening and closing the inventory. This is how I did it (first part of the inventory creation): class_name InventoryUi extends Control # I think class_name should be before the extends var is_open = false func _ready(): visible = is_open # starting as false func _process(delta): if Input.is_action_just_pressed("inventory"): # I like names like "inventory" instead of "i" show_inv() func show_inv(): # no need for separate functions open() and close() - reducing bugs visible = !is_open is_open = visible Less lines of code is always better 😅

[@Nezarus0]

Your suggestion is fine, but I can't get behind the 'less lines is better' line of thinking. More lines is better if it means your code is easy to understand in the future. Do not underestimate how much time you will sink looking at your own code on any larger project.

[@antscologne2962]

@@Nezarus0 Sorry, I switched to "Ants Godot" (my new Godot channel) and haven't seen your comment earlier. You are right: short code might be too confusing. I meant the "keep it simple, stupid" (KISS) paradigma. Don't use additional variables if you already have the visibility that you can toggle, just as an examample. I also like code that you can read without comments and prefer: for line in text... rather than: for i in s🤣

[@Betegfos]

Nice one! Thanks a lot for this. How do you handle saving the game state including the list of items in the inventory?

to toggle inv visibility you can simply call a input function. inv.visible = !inv.visible

[@SchildkroeteHundFisch]

Nice Videos! It‘d be really cool if you‘d build on this one in a regular one, where you make a hotbar…

you could turn this into a hotbar view.. or create a different view of the same inventory into a hotbar

is it possible to store diffrent types in the array , i wanted to make diffrent classes for diffrent item types, like usable and consumable, now i just gave them a enum , but would prefer classes, could also not figure out how i cam use superclass and subclasses , so o can just put the superclass in the array but with the advantages of subclasses

Quick question: Why did you add the panel @ 11:36, and then make its alpha value invisible, when you could just use a sprite without a panel behind it. I'd love to understand what panels do. Thanks!

[@JasonEllingsworth]

I am still very new to all of this, but in unity, UI elements were their own thing that interacted with each other, and maybe godot is like that where you need to use these green UI nodes so they play nicely together.

[@blakefarnsworth]

At 23:10 instead of making a Center Container and Panel, couldn't you go to Offset and unselect Centered?

[@the_oppa7v719]

YEEEEEEES

[@LawlessNate]

8:25 why are you putting this under _process(delta):? Doesn't that make the game run this check every frame of the game? That seems like a needless waste of resources to have the game checking each frame to see if the inventory menu key is pressed instead of just making it a func _input(event): which doesn't react until the correspondingly scripted input is provided.

[@dev-worm]

yes you are correct! that would make a little bit more sense lol, sorry I shouldve caught that!
