how do i make an inventory system using visual scripting?
I have an upcoming tutorial for that, here's a video demonstrating how it works - but the how is pending
foggy roost
ok lmk
foggy roost
i asked grok how to makeone, do u think it will work
light agate
what is an inventory but a list of stuff?
final fern
what is an inventory but a list of stuff?
List of stuff is just one mechanism for an inventory...
There's drag n drop logic, exchange logic, quantity (if any), item ID comparison... Slot data (equipments, items, bag, etc)
light agate
for sure. My method when approaching a new system will generally be to start at the very beginning
a definition for an item, and a container to put them in. Once you can successfully add and remove from that container, work on UI layout and interactions
you will begin to realize as you go what functions your container is missing
it helps if you know what you want your inventory system to do though
does it need tabs, context menus, drag interactions etc.
foggy roost
can i show you what I have, i ran out of grok messages for 20 hours
foggy roost
thats all i have lol
im trying to pick up that object and when i walk over it I get that console error
light agate
looks like something that could work
the red error is telling you
its saying one of your nodes is missing a value it needs
and when you look at your graph it is highlighting yellow/orange to let you know
what question do you think you're asking with that if node? Like, if what exactly?
foggy roost
idk what to do with it
i only am trying to learn i have no idea really where to go generally
my grok history got deleted too so idk lmao
light agate
i susepct grok is not very good for UVS. I doubt you need the if node there
you're meant to put a predicate of some kind into the slot, currently that will always output false as a default
you'd normally be asking if x > y or i == 0, you know, checking for something. If you're not checking for anything just remove it
foggy roost
ok i got this error i deleted the if node
idk what it means to check for something or ask it a question im kind of learning right now lol
also idk if the immediate node was the right one, i changed that too
but it didnt work
light agate
that means you're trying to destroy an asset from your project, not an object in your scene
you must have dragged a file into the destroy node instead of a scene object
foggy roost
its a prefab
its not supposed to be a prefab? or
ok that makes sense
i cant type anything into the destory object node, i have to load it from the list. it had to be a prefab
light agate
ah that is DestroyImmediate, not Destroy
that's more intended for deleting files from your project... kinda, but you just want Destroy if it's for objects in your scene
final fern
i susepct grok is not very good for UVS. I doubt you need the `if` node there
I dont think its grok's fault. output depends heavily on input.
And i can see @foggy roost is beginning and trying to implement intermadiate content in unity without knowing the basics (using IF without a bool connected)
Before you try to implement an inventory system - start with baby steps...
Like adding on player: on trigger enter item detected?, add to list and disable gameobject.
Add collider component to item and mark as isTrigger. Mark item layer as Item (or whatever)
Then in player add node:
onTriggerEnter and extract (drag from) the white paper output of this node, select node "get layer name" and compare using "equal item?" If true?
Add item to list.
Disable item.
foggy roost
oh ok i think i know what ur saying
this is like my 10th time trying this and that i can conceptulize well ill try it later
foggy roost
hahaha
i put this in my player movement scirpt
i added the Item layer to my object and its coliders trigger is active
light agate
u wanna heed your yellow warnings
all your nodes that have lit up yellow/orange
they are telling you to fix some things
foggy roost
I couldn’t find the set layer node I think
final fern
I couldn’t find the set layer node I think
I'll show you when i get on my computer. Make sure tou have "human naming" off in visual scripting settings (project settings)
final fern
Here's what you can do to get the layer of the object, it's not the ideal, but it works. it says Player when my collider of the player enters this item range
foggy roost
i dont see human naming
i also was wondering if my rigid body was not on my player 3 script if that was bad but its a child on the body part in the screene shot
my player script is just on an empty parent of the body
also i changed the layer to Player
and than i copied it, now Idk what to do
foggy roost
lets see
i would need to set the layers on my pickup object
and than put code on player object to disapeear when my player object colides with it and than goes into a list
thats the jist?
final fern
i dont see human naming
Oh sorry its in another window this option. Let me share where it is
foggy roost
theres more code though right, we still have to destroy the object
and is the code I have right now, does it add it to the list or what, and what is the list
final fern
dont i have to set it to a specific layer
What is that "this" of the onTriggerEnter? That object that has this script machie - what layer does it say in the inspector?
foggy roost
Player
this means something also right
i put my pickup object layer as Item
so do they have to be the same
final fern
Share inspector screenshot or record a video showing around
light agate
layer's are basically numbers under the hood, but you arent actually setting anything to any layer there
final fern
In this case, i see you are getting layer of the item. Because this script is in the player.
So check the inspector the item what layer it has - should say Item as your lasts screenie
light agate
you are taking your collider, getting your layer mask as a number, and then converting that number to a string, then logging that string
final fern
i tohught they were like a tag
Tags != layers. Different use 🙏🏻
light agate
you can wrongly use layers as tags, and its not necessarily harmful, just not the intended use
foggy roost
ok so why are we logging it
dont we have to do stuff with it first
like we get the string than it puts it somewhere
to the inventory
light agate
tags are easy groups to use in code
layers actually have functional impacts, like whether collisions will work between layer x or y, or whether your camera can see objects on that layer
light agate
not sure, all i know is you're logging that collider's layer's name
final fern
In this case yeah, because that script is in the player. So that white paper from OnTriggerEnter is getting info from the Item.
But... Player have any collider marked as "isTrigger"?
It only has a rigidbody. Not a collider
final fern
Rigidbody gives access to be affected by physics, such as gravity.
Collider gives data to bump with other objects (or be detected when in range)
final fern
im just dumb
I'd way you're Just starting to learn. 👽
final fern
Now you have successfully done the first part of getting items - which is item detection 🙏🏻
foggy roost
hell yeah
the console logged it as soon as i logged in without walking over it
but all good
final fern
When you say "as soon as i logged" - clicking on play mode?
Maybe because it's on top of the other instead of "walking" to it?
Now the next step is to add the logic when player gets on its zone. You want to disable the item.
So use "gameobject active set" and make sure it has unchecked the box in that node
And from the "onTriggerEnter" white paper output drag and search a node "game game obj" it will give you get the gameobject and plug that into the "this" of the disable gameObject
foggy roost
i couldnt find game object active set and i think ur phone auto correct game game obj
final fern
i couldnt find game object active set and i think ur phone auto correct game gam...
it is how i write in the search box lol
I literally type "game game obj" to get that specific node
try it and see
it says something gameObject.gameObject(get) 😒 confusing, i know, but it does what you need to target the right object
final fern
im opening my project, let me show u
you DONT have to type all, to find the node you want.
you can even add that star, in case you want quick access. but its faster to type like that
foggy roost
wdym by dont have to type all
oh
its cuz i wasnt doing it out of the colider
lmao i see
would i continue it off like the same collider
final fern
that's what i meant when i said "drag from the white paper" lol i dont know why it has that paper
foggy roost
like one that sets the value for the inventory, 1 that makes it disapear
final fern
now that you have that rference to the gameObject, connect it to the set active false
foggy roost
sorry i got lost with what you said earlier
final fern
foggy roost
oh white paper as in the later mask?
layermask node icon*
and i ticked it active
foggy roost
k ill copy it ty
final fern
you change the STring Player for whatever
In this case i think it should be Item
if you want to detect if the thing netering your isTrigger ocllider is a Item
then vanish it
foggy roost
sry i got this error i think its from my player movement script
im trying to figure it out
i didnt even change anything lmao 1 sec
this is my other movement code btw on the same visual graph idk if it might interfear
final fern
where is the red node? dont quit play mode yet - you can check the script on the go. you can pause, and hide the blackboard wit hvariables to speed it up if it needs to
clicking the console error sometimes sends you to the object containing the error
and add this addon made by X7 to find the red nodes when they show up. It's a nice debugging tool to have.
Just drop it in your project files in Unity editor
foggy roost
it brings me here when i click on the error
final fern
it brings me here when i click on the error
not double click, just one click.
foggy roost
sorry i dont see any nodes that are yellow or red
foggy roost
i moved it to a scene with a different player movement script and it worked
the only thing is when I set a trigger to a box colider on my guy he goes threw the floor now lol
when I make the box collider a trigger I mean
idk this is the code for it
light agate
we need to see screenshots of them in-action so we can see what values you're passing and what might be breaking
final fern
Do you know how to record screen? There's a free app ShareX you can use
final fern
the only thing is when I set a trigger to a box colider on my guy he goes threw ...
So how does the inspector of those coins (balls) looks like? What components do they have?
final fern
idk this is the code for it
You should use the new input system, as the old is gettin deprecated (saw this message not so long ago)
final fern
Reaches Finish, load next scene. A racing game? 🤪
light agate
u can Win+Shift+S, windows has a native screen-recorder
i really need to learn the new input system sometime
final fern
It is really easy, in fact some of them work as events (instead of using onUpdates and if true checks)
https://discord.com/channels/489222168727519232/1405549841400201266
I made a tutorial of player movement and it shows the new input+ uVS - like last year
foggy roost
I can screenshare with nvida if i load a game first
the game Is not a genre though. but the tutorial was a block that went foward so i made it into a racecar
maybe a bunch of different games
it has a physics material on the racecar i forgot what that does maybe
foggy roost
I want to make it like though You beat single player, you get duo player, triple player, quad player and than its like a mmo after that and than create BTC for items
i think thatd bee sick, the value stays with the player but Im mostly just trying to make a single player obviuouslly but thats what i want to do
like one day when i have 500 trillion dollars
omg
i make the currency a fucking cyrptocurrency
im cooking
foggy roost
also if u have like a simple player script i can copy and duplicate the scene or something it might be easier
final fern
also if u have like a simple player script i can copy and duplicate the scene or...
What do you mean?
Its best if you learn how to draw than cloning
Assuming you dont know c#, the hardest part is knowing what nodes exist and what methods can be used to add logic working.
Because there's many ways to control a player. And some might seem the best and maybe not
foggy roost
ok can you teach me than
🙂
i can try and make it first right now
ok i got it, i deleted the head and all the nodes in my last player script and now its ok
Sorry its all over the place xd
so now I need to destroy the object when I pick it up
im trying to understand the code though
like can you just explain the layers again, are we converting it from an int to a string just to read it?
final fern
click on play mode, and get these nodes activate (they turn blue) when it triggers. so when it does, there's going to be here some words... show us what does it say
foggy roost
shouldnt the layer be Item instead of player i feel like thats why im most confused
like if im colloding with a item, why would i name it player in the layer
like should i name it layer or does it need to be player layer and the item layer is something else
final fern
like if im colloding with a item, why would i name it player in the layer
It was an example, thats why i said better learn the logic flow than cloning the nodes
If the onTriggerEnter is in the player, player wont need to detect himself.
Would it?
So what is entering player's range?
Thats where you compare.
Is it item? Is it enemy? Is it spikes? Is it lava?
foggy roost
are you making an aillien game like destory all humans
that game was goated i dont even remember anything but it being great lol
final fern
that game was goated i dont even remember anything but it being great lol
eehh. no, aliens are not bad on my story. They are the saviors of hte universe from mischief makers like humans and their machines built who took over their own world.
foggy roost
hahaha
foggy roost
so what do i do now
final fern
Think.
IF it's ITEM, then change that string
play game and keep this script graph window open, when you get near the ITEM, see what string appears there
foggy roost
i showed u tho when i click play it disappears
idk how to keep the graph open when i click play
ok ill try to change the string from Player to Item than set the layer on my pickup objet as Item
i was confused the whole time about that
i am confused on why though its like set to the false section of the if statement im not sure if its cuz i dont understand the future code or what
but it will look better to me in the future i bet
final fern
you only want the flow to move forward from that IF - ONLY when it is the exact layer you want to detect, in this case: Item
foggy roost
ok so set active to false after the if statement at the end makes the object disappear because its false right?
final fern
Yeah
When you select an object in the hierarchy, you can use keyboard:
alt+shift+A and you get the same result. You switch it off.
And when you see inspector, that checkbox at the top gets unchecked. (The one that can be clicked)
That "check" is the same you see in the node, in your graph
foggy roost
Coo
so whats the next step, its in a list and it disappears, should i make the ui now
final fern
You added item to a list?
It depends on what you want to do with that item. If its only display what's in the inventory, then you need UI + Grid layout + sprite holders
And make a gameobject variables for each item that carries its own sprite, text details, etc
In my case, i used an AOT Dictionary for each item slot inside the UI inventory
So it carry info for that slot:
itemSlot (what position in the inventory it occupies)
itemName (to display HuD)
itemType (weapon? potion?)
itemQuantity
itemSprite (to show image in the inventory)
So every slot inside that grid have this variable.
Say you pick up item. That item have this same dictionary.
When its picked up, you copy this variable data to slot data.
And thats it
foggy roost
that makes alot of sense, i did the exact same thing in a tutorial but the other half needed visual scripting plus so i couldnt finish it, nor did i understand the code at all
where do i put the grid layout component, i make a canvas right
final fern
I got that uVS plus thing - when i started 1 year ago, its not good. Pure subgraphs and sometimes you dont even know how it works.
As i said, logic > flows > nodes
You cant learn via templates
foggy roost
true
final fern
where do i put the grid layout component, i make a canvas right
Yeah, ui requires canvas.
It has a few grid options. Cant remember the name. But you put in a parent gameobject component, and then the childs inside auto aligns
So you define the size of your inventory grid in there. 3x3, 5x3, 5x5 - w/e
foggy roost
yeah and the child is just an image right
final fern
yeah and the child is just an image right
Its a prefab, gameObject with variable component ("itemData" aot dictionary) and image component (to display the sprite from the itemData if it exists, it replaces it or else show default "empty" version sprite
Its a prefab duplicated for each inventory slot.
You edit one, they all copy the original (like adding a new key+value for the dictionary)
Or adding a background sprite for the item sprite
Here's when i think "prefab variants" works best.
But i have yet mastered that 🤪
final fern
Type in there:
"AOT dic"
You'll get a dictionary type of variables. And have all item data in one variable easy to clone between dropped item and item in inventory
An AOT dictionary will show 2 blocks of variables. Keys + Value.
Key once saved cannot be changed or reorder
"ItemData"
Variable AOT Dictionary
Name | Small Health Potion
Qty | 1
Type | Potion
Sprite | Image
And you can choose what type of variable each key and value needs.
I usually use string for keys. And then change value type for whats needed
Qty uses INT
String | INT
Sprite needs an image sprite
String | Sprite
Play around with it you'll see how it works.
When you pick item, (the graph you already have - right after disabling item) you trigger custom event "itemPickedUp" and send 1 argument with it ("This" node. It sends the item gameObject).
The inventory script receives this custom event and use a node "for each loop" (dictionary checked box)
Get the argument 0 from that event, and connect a node "get variable: itemData" and connect that to "for each dictionary" node input
Then the inventory, who has a list of all slot prefabs, does a check which is empty, and use that slot.
"Set item dictionary" and connect key to key, value to value. Voila.
foggy roost
you said for the type variable it matters like more on the mechanic of them item?
also what do i do with the aotc dict
for item name
final fern
"ItemData"
Variable AOT Dictionary
Name | Small Health Potion
Qty | 1
Type | Po...
Read these again. Play with that variable until you find its logic
foggy roost
kk
foggy roost
this is what i tried to do, I put all the variables on the Itemslot prefabs, the pickup item and the player object
final fern
Thats going to give you error
Cause you are going back n forth with set variable outputs
light agate
I wish UVS had a fnCall that wasn't a catch-all event broadcast
final fern
I wish UVS had a fnCall that wasn't a catch-all event broadcast
what do you mean?
foggy roost
what's the difference between keys and value in aot dictionary are they for variables like keys is for the name and value is for the string? or something
like i dont understand aot dictonarys purpous
light agate
what do you mean?
in code you just call a function directly, in UVS you have to broadcast an event. In practice this is a tad spray-and-pray. It broadcasts an event and any number of listeners catch and determine if it was meant for them. It's needlessly expensive
foggy roost
whats an event
final fern
whats an event
just like in real life: something happens
and then, there are conditions which lead to consequences
event > condition > reaction
Damage > Hp = 0? > Die.
foggy roost
oh
i dont get if im supposed to have the item variables on my player, my pick up item and my prefav for the inventory slots
was my main question honestly
also is it fine that the box connecting my item variable is from the get gameobject before the object disappears
final fern
i dont get if im supposed to have the item variables on my player, my pick up it...
I think its better to have a gameObject somewhere in the scene that saves this data for the player
You could use app variables as well, there's many ways to do it
The important thing afterwards is the ability to "save" and load. And thats tricky. To get there, it helps to get these basic data transfer between objects
foggy roost
and what do i do with my code
idk im stuck with that
i dont even know what i coded lol
final fern
Make sense of it before you continue
final fern
what are app variables like global varaibles idk
App variables are application, they are saved as an asset ( a file in project). They dont get erased as long as game is running. Anyone can access it.
heavy ravine
what's the difference between keys and value in aot dictionary are they for vari...
key is the name of something ,and value is that something
keys are strings and values can be anything, like integers, strings, bools, blah blah
final fern
what's the difference between keys and value in aot dictionary are they for vari...
Key is like the box. Value is what's inside.
You call the box by its key. And get what's inside or change it if you need to.
For example, i use this:
EnemyBaseStats.
That's the atm variable name.
It has these keys, and value of each separated by |
Hp | 10
Damage | 3
Speed | 5
So lets say they "rush" so i set their speed x2 , and then reset back to their default.
Get dictionary item, key Speed = output will be 5.
I get stats from a dictionary and save them locally as graph variables.
I need to modify all enemies stats?
I dont do it one by one, i change this dictionary - and they reupdate it on their own graph variable on event (update stats, on enable, on respawn, etc)
foggy roost
so now I need to put my variables in my item slots in my inventory right? and than its done?
for my hud
final fern
so now I need to put my variables in my item slots in my inventory right? and th...
Well, apart from saving data in your slots variable - you need to update the slot sprite when you do that, so it shows
And there's an additional feature you have yet asked. I assume you know how?
Getting mouse events.
On enter, exit, hover, drag drop.
With that you can move things around or delete one of them or use/equip it
foggy roost
i know nothing
i was just farmillar with the parts we are doing but i couldnt replicate it or do it on my own
i was just saying i understood wut u wuz sayin a bit
once I get the inventory system though Ill try and do some stuff on my own
final fern
Well, i nerded this for 3 weeks, 8 hours a day and stumbled many saying its easier on c# and not really doable in uVS 🤷🏻
Back then it felt impossible
But you can cross that barrier and do it
final fern
Best tip i can give you: think of the game logic before you code
foggy roost
so if my itemslot is a preefab, i need the variables to show up in the prefab right, the hud
final fern
honestly i am learning where on c# i wasnt learning
Yep this is the reason im starting a project, to teach game logic via graph flows. Its on my list. To build tutorials that share the fundaments that makes these things work.
final fern
so if my itemslot is a preefab, i need the variables to show up in the prefab ri...
Hud >> UI. In unity its Canvas. And the modern way is called UI toolkit (have yet touched it)
foggy roost
can i skip the dictonary though
final fern
i dont learn from tutorials
You won't learn from tutorials, i tried. Most are c# experts trying to explain as if you already know a thing about it
And since i know like 0 c#... I didn't understand lol
foggy roost
is it just to make it easier or more convienet
final fern
can i skip the dictonary though
Sure. You can. There are many ways to get the same result
foggy roost
ok cuz i have no idea how to use it lol
final fern
Haha I'll make a video on monday showing you how they work, i like them a lot. Very useful
Your UI only displays 2 things: the sprite and the description (quantity, name of item, etc)
The itemSlot is responsible to put it where it renders, so that's semi automatic
final fern
is it just to make it easier or more convienet
I find it easier to clone as many data, from one object to another - in 2 nodes.
Again, i took codeMonkeys uVS course. Udemy gameDev uVS course. They explained pretty basic things
Tried to see a full c# course in YT .. and didnt get a thing
But!
I learned to use Gemini (google AI) to find what nodes i need. You know, the thing you type in the fuzzy finder.
Once i understood the game logic, not the programming code, i came up with "problem solving" process that allowed me to build an inventory my way (including save load system) which im sharing with you
Cause my #1 problem was.. like...
Ok i want to do this. It works like this.
But how do i get that running?
What is the "function" or the "keyword" to connect events with presents?
foggy roost
brb
final fern
The rest is kind of learning Unity, how it works as a platform and their lingo
foggy roost
why does the string say itemPickedup on it
final fern
You mean the trigger custom event?
Have you used them before?
My favorite node. Once i got how they work - oof made things easier
https://youtu.be/iHtaIMx7Kfw?si=ayU12jBjXdW4E5oW
I made this video last year hoping it helps anyone looking for it
foggy roost
i probally shouldve tested it, i assumed it was wrong and forgot
final fern
Hmm if you could explain this logic, what is this supposed to do?
foggy roost
i tried this instead
i think custom event arugments changes the varriables of a game object from the object being picked up and than i tried making it set in my item slot prefab but it didnt work
final fern
Did you see that video i shared?
foggy roost
yeah its just my brain dosent work so i have to rewatch it
final fern
Its because you need to experiment with those and test, thats when you learn
Doing. Doing. Doing.
light agate
Yep. Can be more effective than tutorials, often
final fern
Yep. Can be more effective than tutorials, often
Exactly, and cloning what others do - not good.
get your hands dirty, exploit red nodes and keep testing - it will click somehow
foggy roost
oh is custom events just a number of how many times an action is performed
so itd occur 3 times in my code
thats what i orginally thought it was
oh also
do i want the varriables to be from my item slot, not my pickup object
i lose track sometimes of the objective honestly xd
final fern
i lose track sometimes of the objective honestly xd
If you write in a paper, how does it behaves step by step. How would it looks like?
- player gets near item
- item is picked up
- item disappears
- ....
foggy roost
yeah exactly, than im trying to get those values to be put into my item slot
lets see
i want to put those variables into my itemslot variables
of them item i pick up
idk how to like set them though
and i probaly dont understand custom triggers somehow lmao
final fern
Complete the list!
final fern
If you write in a paper, how does it behaves step by step. How would it looks li...
- item data transfers to players inventory
- inventory displays item picked up
- item displays data on mouse hover or click...
Keep going!
light agate
yep, time to grab your pen and paper WoW (or keyboard). Write down the steps you think your inventory system takes, show that to us and maybe we can grill it
Litoid just gave you an example, but you need to fill out the numbered list of steps yourself. For your case in particular, because it isn't just UVS you're trying to understand here, but programming instructions in general. You will be able to guess your way through a system, or google what's available, once you can clearly state what your system needs to do, step-by-step
final fern
Exactly. game logic flow > coding program mechanics
foggy roost
can you tell me what my codes saying right now tho at least
just so i can learn and change it
i dont really get custom event trigger argument
i need something to change the variables or set them
final fern
when item enters player's zone (thats true?) then deactivate that item (make it disappear). then send it's quantity, name and sprite to this event, and the object listening to this event is the same item gameObject (the cube input) and then save itemSlot as the empty variable
this is what it says
when item enters player's zone (thats true?) then deactivate that item (make it disappear). then send it's quantity, name and sprite to this event to player's inventory (connect player's inventory gameObject to that)
And then the rest should continue after the custom event is called
think of custom events like a portal.
Trigger Custom Event is the entrance (where it goes through), and Custom Event is the exit (where it lands)
the string you put in that empty textbox - is the "ID" for this custom event, and the gameObject input port is "who in the hierarchy will receive this event"
foggy roost
thanks
foggy roost
ok im watching ur video with my brain more turned on and its actually clear said
my bad
im just afraid of coding tbh
i got this error
when i dissconnect that thing it turns orange
so like thats why theres so many itemslot refrences, im actually not sure the best place to put the refrence in the code
but did i do anything right?
and heere is my pickup item variables
sorry, i didnt show that earlier probally its hard to follow cuz im dumb
i feel like im close now 🙂
ok i fixed the error
i think
but my item sprite didnt update in my itemslot
nah i def dont understand it lmao i just gota watch the video again until i get it
probaly
xd
foggy roost
also im trying to get the object variables of the pick up object and "this" only gives me object variables from the player object you know what i mean
idk how to get the variables object from whatever im picking up
like if i save it to scene or app than its not going to be unique to whatever item i pick up
nvm i think i just keep forgetting what things mean
final fern
ok i fixed the error
This one is good way of doing it
But it doesnt have to be in the same script, add another gsmeObject in hierarchy and sdd new script machine (playerInventory) or something
And there you put this custom event (the one on the right eith saving variables (the set nodes)
This gameObject is parent of maaaany itemSlots.
Inventory
itemSlot 1
itemSlot 2
itemSlot 3
And so on.
And in your player, add "object variable" type gameObjecy and drag this "Inventory" gameObject there
And this variable you connect to the "trigger custom event" gameobject input
This way the Inventory's scriptmachine will listen to this event
And then be able to catch these variables
Try that before updating the sprite. To actually save data to the itemSlot

@final fern What happens when you provide an input to a get-variable node like in his first image?
I never understood why get-variable nodes had inputs, they just output whatever value the variable is set at in the graph, object or scene

You mean this?
the orange dots are string type inputs, if you dont connect anything it uses the value you write down, in this case "itemName".
the cube type is gameObject. if you dont connect anything, it uses the gameObject where this script is attached (i.e. the Player). If you connect, say inventoryManager variable into this, then this "get variable" will get itemName variable FROM the inventoryManager variables, and not the player.

Remove that, let it be "This" by default. you are "listening" to a event in a gameObject not present

im confused a little....
ok i see, so object getVariable nodes in particular can take other inputs.
If you provide a GameObject, does it sample the Variables component on the chosen GO?

its because you are sending this event to all of them? hmm
final fern
ok i see, so ***object*** getVariable nodes in particular can take other inputs.
when you need a variable from another gameObject, yes. this input does that
this is how different gameObjects uses their "public" variables that in uVS is called "Object Variables" - can be seen, and modified by other scripts (gameObjects)

i give up
i deleted unity
i dont want to be a coder lol
I just need ai to be better

One point for my curriculum:
Dont start building systems, level up by making steps.

I don't mean any shade to WoW, but I bet it will become more and more common for people to endeavour into programming tasks with the expectation it should be straightforward. There will be less tolerance for the friction presented as programming's participants become more and more general-audience. People are vibe-coding web-apps because AI is quite reliable with more ubiquitous and universal text-based stacks. like HTML/CSS/JS and or Python and any of the tools that can simply be tacked on by editing a text file. Needing to understand Unity Editor, all the menus and windows, to even know what to do with the code AI gives you will start to be seen by many as quite a barrier.
Unity have already been evolving in light of this for a few years now, with latest Unity 6 having integrated/on-board MCP/AI. People can almost reasonably expect to tell it "Make a platformer where I can pick up items, then inventory should be like Baldur's Gate but the gameplay should be like Astrobot".
A Regan of the 1970s might never have picked up programming, it's only thanks to more modern conveniences that with my poor logic and maths skills I was still able to make a start and 15 years later am finally a tad competent. But if I started with how programming used to be, I might have had no shot. I'm a competent programmer by modern standards, but probably a pretty incompetent one by 1970 standards.
Still, I think the best approach to understand is not to dive headfirst with AI. It's great but you can get led astray if you're not asking it the right questions, the kinds of questions you can only ask when you already know a little about the topic.
I know when I was learning I read lots and lots of forums, and EVERY time I came across a term I didn't understand, even "what is a variable?", "what is a const?", "what is a method?", "what is return?", "what is ternary?", I would google and read official unity docs, microsoft docs, forums. And in some cases, like when realizing Quaternion seems more relied upon in game-dev than Euler for rotation, putting in the effort to read a full wiki page on just that topic, as well as additional resources.
I really believe anything is possible, and anyone can do it, but reading is important. Unless willing to read documentation and full forum posts and articles, I don't think you can get far. I have taught at tertiary level before, and just that willingness to read has been a noticeably HUGE difference between the students that not only pass but SOAR, and those who fail or get just past the 50% grade-check.

This is an interesting comment you share, thanks for that. I hope more people persist during a struggle phase - cause that's when we usually grow, but most people are not "trained" for consistency. I remember when i wanted to quit when things were not clicking on me, i had a very bad days back then - but i was stubborn, and now im here - still on my journey.
And I agree: Self education is and will always be the best way to learn.
Not hoping someone to take our hands and walk with us, but the willpower to research by ourselves.
But here's where I disagree.
Reading may be good, and i love it - and because i do, is the reason i'll say this:
Knowledge without action will never turn into wisdom.
Reading is just knowledge.
Its good to break the system, get bugs and crash the editor - this is how we learn long term 🤪

oh yeah absolutely
we learn a lot just by trying, it's not all reading
but when someone asks me about an object pooling system but then DOESN'T read the object-pooling article I send them because they don't like reading, I mean.... I've provided the info lol
But i get that sometimes people can reach the profound conclusion through a more practical avenue
for example, you sometimes have been using a technique that just made sense to you personally, for months, years, and to later encounter someone talking about it, and discovering it's a well-known pattern/approach and even has a name, and people sometimes go out of their way to learn this pattern, but you've been using it all along by accident.

sometimes it's just a keyword missing, but the game logic is the FUN-damental 🙂

it was a hypothetical kinda, now so long passed that it doesn't matter
but for interest's sake, the catlike coding one on that topic is pretty lit
https://catlikecoding.com/unity/tutorials/object-management/reusing-objects/
and anything from this ebook on the topic is A+
the whole book is A+
but, actually the context i was recalling was C# users, not UVS
I can definitely imagine why someone would go "no, I'm not reading that", but we're lucky there is pretty much a youtube video for everything now

have you tried vibe coding with claude in unity though?
light agate
only if stuck really, or if the task is so straightforward that it'd just be a chore for a human to do
lot of us use it but it all has to get reviewed by humans anyways. Accountability is important, so it is fine for devs to use it but they also need to be able to explain how the code works later
good for first-pass

I saw this one when i investigated object pooling and understood almost nothing lol
I cant read text firewalls, c# distorts my view :/
I think these type of articles would benefit from visual analogies. Now that i know what is object pooling and actively using it - I imagine computers doing this:
No object pooling:
- right click, create new file
- Right click, delete file
- empty trashcan
Object pooling:
- generate 20 files at once
- drag from folder to root to display
- drag to folder again to hide
But thats just me and how i process data 🤷🏻
