this will not fly forever unless you have disabled gravity

[mild onyx]

what i mean is i can spam the space bar and it will keep going up, i want the space bar to not work until i touch the floor again

[ivory bobcat]

Are you referring to not having any extra motion simulated relative to your velocity you've added?

[mild onyx]

this is my first time with c# and i know NOTHING

[wintry quarry]

Yes typically scripts do a "grounded check" to make sure you're on the ground when you try to jump

You should find and follow a basic tutorial.

any basic tutorial will cover this

[mild onyx]

the tutorial i was following was for flappybird

[wintry quarry]

ok well flappy bird jumps in the air so

what did you expect

find a different one

[ivory bobcat]

You'll need to find a tutorial for single/multi jump etc (plenty of unity tutorials on the internet that would better cover this than discussing it on Discord)

[stuck palm]

can you not serialise vector3's?

[mild onyx]

ik i thought i could steal stuff but so far c# seems alot harder than pyhton, then again i never coded a game in python

[wintry quarry]

You're trying to serialize the normalized property

how did you install newtonsoft JSON

[ivory bobcat]

Making a game is pretty hard unless you're making something simple or are lucky to find reference material similar to what you're wanting to make.

[stuck palm]

via the package manager

[stuck palm]

i shouldnt be

[wintry quarry]

can you show your code

[stuck palm]

void SaveReplay()
    {
        string json = JsonConvert.SerializeObject(_replay, Formatting.Indented);

public class Replay
{
    public List<ReplayPlayer> _replayPlayers;
    public LevelEnum level;
    public List<GameState> stateList;
}

[Serializable]
public struct GameState
{
    public List<Vector3> playerPositions;
    public List<Vector3> playerVelocities;
}

I'm just tryna serialise this object

[wintry quarry]

You have to be carefuil with newtonsoft

it tries to serialize properties by default

[ivory bobcat]

Tbh, you probably can as long as you know what you're doing and are able to integrate the resources together.
No one really cares about theft of code (especially from a tutorial), cheating (modifying json files) etc
Assets are a no go though.

[stuck palm]

how can i avoid that

[wintry quarry]

Well typically I carefully curate all the objects I'm serializing with newtonsoft and use the "OptIn" approach as such:
https://stackoverflow.com/a/55046228

If you really want to reuse builtin types like Vector3 it gets more complicated

so rather than serializing Vector3 - I would make my own serializable Vector3 with the appropriate annotations. And perhaps an implicit conversion operator between them

However... afaik this is supposed to be included?
https://github.com/applejag/Newtonsoft.Json-for-Unity.Converters

so I'm a little confused why it's not working

[stuck palm]

thats annoying lol, how can you program a conversion operator?

[wintry quarry]

I mean actually this specific case is referenced here https://github.com/applejag/Newtonsoft.Json-for-Unity.Converters?tab=readme-ov-file#what-does-it-solve

I just though thtese converters were iincluded with the UPM package but maybe not?

I guess maybe the UPM package doesn't include this by default so you have to add it

[stuck palm]

how do i add it? via git on the package manager?

[wintry quarry]

installation instructions are in the link

[stuck palm]

oh i see soz, thanks will try this

[ivory bobcat]

This one seems visually similar to yours https://youtu.be/P_6W-36QfLA?si=Kvfx-AsRl7vXJUcc
(Random Youtube video)

[stuck palm]

just to clarify im using this package

[wintry quarry]

I know

the converters package is separate

[peak python]

hi, not sure if it is a beginner or advanced,
I am used to building 3d games with physics, like golf for example.
Now i am trying to build a simple 2d game where you can drop items that destroy ground and move car from left to right.
The thing is, i am trying to make ground to behave like sand - so if i destroy the ground, it would be filled from the sides ( like sand ) but it would become uneven, so i want it to behave like fluid, but not as water.
My first though was to make a bunch of square bodies, and when i drop the item that destroys ground in radius x - just get all the bodies that are withing radius and delete them - making unity physics engine do its thing, but, i am afraid it would tank the performance and that car movement from left to right would become unstable (because of wonky physics considering large amount of small square bodies that make the ground)
Or there is already a premade sand ground that i can use, that i didn't find.

[mild onyx]

ill have to check it out tommorow but thanks, tried to add some horizontal movement and my character rolls instead of sliding😂 , ill have to see what i can do tomorrow

[wintry quarry]

Yes it would probably tank performance. Consider using an asset such as: https://assetstore.unity.com/packages/tools/physics/obi-fluid-63067
Or consider using compute shaders or ECS.

[ivory bobcat]

Constrain rotation etc from the inspector

[stuck palm]

just installed the converters package. do i need to do anything else for it to work?

[wintry quarry]

Worth reading this section: https://github.com/applejag/Newtonsoft.Json-for-Unity.Converters?tab=readme-ov-file#configuring-converters

[peak python]

hmm, i guess i can simplify it,
so i can still make a lot of small square bodies, but after the .eventDestruction
i would go in a loop
and descend any body that has no body below it
so that i do not get the floating in the air sand

oh wait, i can just give them gravity speed, no need to loop over

[stuck palm]

ah okay, thansk

[peak python]

this should make it easier on the cpu, since the only processing would be when it is going down - which is simple gravity

[stuck palm]

im getting this error, now. no idea what the particle system is doing in there

[Serializable]
public class ReplayPlayer
{
    public CharacterEnum character;
    public int characterColor;
    public int characterID;
    [JsonIgnore, SerializeField] public PlayerInputController inputController;

    public int frameLength;
    public List<InputPacket> InputPackets;

Does jsonignore not work with the new converters?

[wintry quarry]

JsonIgnore should work fine...

[wintry quarry]

Make sure you're using Newtonsoft.Json.JsonIgnore and not System.Text.Json.Serialization.JsonIgnore

how do I add an overhead ui to an object when i have my mouse over the object

[eternal needle]

Which part do you specifically struggle with?

[teal viper]

Have a world space canvas that you move around and activate when needed.

[noble reef]

uh tryna add a canvas to my object

whats a world space cnvas

[teal viper]

A canvas set to render in world space.

Check the canvas page in the manual to learn how it works

[noble reef]

can u send me the link to it

[eternal needle]

Your canvas shouldnt be on your objects, your objects should be children of some canvas in the scene

[teal viper]

Don't expect people to google for you.

It's really easy too. Just type: "unity canvas manual" in google and hit enter.

[noble reef]

oh i thought it was somewhere in unity

[teal viper]

It is. In unity manual. And you google to find the link.

the conveyor on left, if yo ucan see the ores just get stuck
and conveyor on right the ores somehow dont get stuck
idk why this is happening can anyone help?

[violet elbow]

Hi everyone,

I encountered an issue with items after saving and loading in my game, and I need some help.

I am trying to save itemStateData at the end of each day by calling the Save() method, which saves the data to a JSON file. When the game loads, it retrieves the item states from the JSON file. However, after loading, the items on the ground can no longer be picked up.

Here is the relevant code:
https://gist.github.com/Cindylanlan/06a9ec8bbe64ad227bc5c3e1a7c126b1

Can anyone help me figure out why the items on the ground cannot be picked up after loading the game? Thanks a lot!

[weak talon]

i dont know what else to write about it,

private void OnTriggerStay(Collider other)
{
    if (other.gameObject.CompareTag("Ore"))
    {
        rb = other.gameObject.GetComponent<Rigidbody>();

        Debug.Log("DAOWJID");
        rb.velocity = (conveyorDir.transform.forward * conveyorSpeed);
    }
}

that is my conveyor code
where if it collides with gameobject tag ore then it sets velocity, i have no idea why it doesnt work on one side of conveyor but works on the other

[weak talon]

also i am looking at it now and it sometimes works and sometimes gets stuck?

but just one the one side where dropper is on left side

[summer stump]

Show the inspector for the ore. Specifically the rigidbody settings

[weak talon]

this is the prefab

and this is in inspector

[summer stump]

I wonder if it is the fact that it is a box collider. Catching on the conveyor.
I assume that is a box as well?

[weak talon]

there is a collider that is set to is trigger and that is the one sticking out the top and another for the actual conveyor which is on the black box

its extrra weird because somehow the dropper on the right is working and not getting stuck
but dropper on left is getting stuclk

i think it is just a chance thing because the one on the right got like one ore stuck

[summer stump]

I would try just making the non-trigger collider on the ore a squashed capsule. Scaled to be close to the box shape, but it will have rounded edges

[weak talon]

i tried that and im pretty sure it just fixed

why does that just fix it, i dont understand

[wind brook]

tutorial I'm working from

[summer stump]

Boxes catch on the edges of other boxes.
The positioning is never going to be EXACTLY perfect no matter what, so tiny lips may be catching. The rounded edges just force the collider up over that lip

[weak talon]

ok that makes sense thank you so much for the help

[eternal needle]

you have an extra semicolon on a method, usually you should look at the topmost error

not the bottom

i only really noticed because i pasted it and saw the top most error as well

[summer stump]

Now that I knew what to look for, you have TWO methods with semicolons

I looked for that in the for loops (a common place) but skipped the methods

[eternal needle]

this also indicates your !IDE isnt configured, or you wouldve noticed some errors way earlier

why this freeze unity editor?

[rich adder]

how large is the data ? also Replace returns a string

also why \\", "\n" ? shouldn't you format your json properly in otherway

[nimble apex]

ok so the UI here is a custom GUI made by my former team member
you put in json strings on the "text area", and fire up the events to make the UI work, how the UI work is not important, because it works well, the only question is you need to get in some json string, if the json string is too long and complicated , it will hurt ur eyeballs , because this UI will not do formatting, you need to do it urself if u want

the code above is what the formatting button does

and the result of ANY existing json formatting, either jsonutility, jsonconvert by newtonsoft, all turns the string into something like this

it does not implement indentation, but putting slashes to the string

this is what im trying to solve

but after 4 hrs of work, it seems that just by non-plugin codes or any approaches, u cannot format well json string in a text area UI

i think its time for me to step back and start another task

hi
this isnt really a bug but i want to make my conveyor movement with the ore more realistic

right now with this code
private void OnTriggerStay(Collider other)
{
if (other.gameObject.CompareTag("Ore"))
{
rb = other.gameObject.GetComponent<Rigidbody>();

        Debug.Log("DAOWJID");
        rb.velocity = (conveyorDir.transform.forward * conveyorSpeed);
    }
}

it works on straight lines but when it turns it goes instantly and looks really fake.
This also makes the ore sometimes fall of the conveyor when turning and it is pretty annoying

anyone know how to fix this or make the conveyor movement more realistic and fluiudy?

i have tried rb.addforce but i dont know how it works and it just speeds up infinitely and slides of the conveyor and is way too fast

[slender nymph]

i'd recommend doing some more research on the topic of factory games to see how they typically set up the conveyors. they don't typically use physical objects, especially not individual rigidbodies for the items on conveyors because if you have more than just a few dozen it starts to really lag

[weak talon]

ok thats fine
how do i make higher gravity in the unity scene, like things look floaty

[slender nymph]

i'd bet the issue is you overwriting gravity rather than "too low" gravity

[weak talon]

well when the ore drops from dropper it looks so floaty falling down to ground

[slender nymph]

and if you are assigning to velocity anywhere and set the Y velocity to 0 then you keep overwriting the effects of gravity. for example this line rb.velocity = (conveyorDir.transform.forward * conveyorSpeed); assigns the velocity on the Y axis to 0 unless the object is pointing a bit up/downward

[thorn fiber]

Looking into making a radar for an RTS. Want to allow terrain/structure screening.

I considered raycasting for the most realistic option (casts following the animation of the radar dish) but I assume that's going to spiral out of control, performance wise. So I'm back to a massive trigger collider and raycasting only the unit-type objects within that. 1. Is my assumption correct? 2. Is there another way I'm not considering for this?

[slender nymph]

raycasting is fairly cheap

[thorn fiber]

I know it is per cast, but for a radar I need it to cast at potentially more than 360 degrees. As in, if the angles are too spread, it may not find things at distance. Is it cheap enough to handle something like 2-3 of these objects per player (lets say 4 players max for now) casting at about 720 rays a sec (each)?

[slender nymph]

profile it and find out

[thorn fiber]

hmmm, fair point. The casting method does open some functionality that I would have to fake in a trigger collider solution, so probably worth testing both.

Thanks!

[keen dew]

In general you can do several thousand raycasts per frame without any noticeable difference in performance

[hasty sleet]

The profiler wasn't super intuitive when I tried to use it. I spun my wheels for a bit but it wasn't straightforward, and I was using the official docs as reference. Probably just a skill issue on my end, but other profilers I've used seem more doable

I'm crutching on an FPS counter right now. How regularly do you profile and how easy is it for you to interpret?

[thorn fiber]

Ah, that's a really handy baseline to know, thank you!

[slender nymph]

to add on to this, i benchmarked raycasting to see how demanding it is and i was able to do over 1000 raycasts in a very short amount of time. granted it was in an empty scene #💻┃code-beginner message

[slender nymph]

profile when you notice performance issues or when you need to find out what is impacting performance the most 🤷‍♂️

[hasty sleet]

My friend has a relatively slow PC and is negatively impacting the input response time and causing camera jittering, but my PC can handle it. I'm running the profiler but it is unclear what should be focused on. My current approach is to tweak the execution order of camera rotation and player rotation

[slender nymph]

are you sure you aren't doing something silly like multiplying mouse input by deltaTime

[hasty sleet]

lemme check

I'm using Time.unscaledDeltaTime as a multiplier which is in the Update() loop

[slender nymph]

don't multiply mouse input by deltaTime, it is already framerate independent so doing that multiplication just makes it dependent on the framerate again and ends up causing stuttery camera controls

[hasty sleet]

Added a bunch of physics cubes to add lag and the camera movement has no visible jitter. That was probably it. Thanks!

[weak talon]

how do i fix?

when i click play it works, then when i click to place something the game just pauses

[remote lynx]

probably infinite loop bro

does the editor pause too?

or only game?

[weak talon]

just gasme

as if i just click pause

[remote lynx]

then you probably changed Time.timeScale to 0

[weak talon]

but i havent

[remote lynx]

check project settings -> physics -> Time Scale

when it pauses

[weak talon]

am i blind i cant see time scale

btw it like literatly pauses my game.
like the pause button at the top is blue

[remote lynx]

oh sorry its in settings -> Time

there is Time Scale

[remote lynx]

can you send your code that places things?

[slender nymph]

check the console and make sure that there are no errors. if error pause is enabled then it will pause when an exception is thrown

[weak talon]

maybe it is inf loop
i changed 5 lines of code and basically swapped positions on 2 objects

[slender nymph]

an infinite loop would cause the entire editor to freeze

[weak talon]

hmm yeah

the blue button where you pause is clicked

and i cant unclick it

[slender nymph]

then stop ignoring the errors in your console

[weak talon]

i fixed it, the editor didnt freeze but there was a line of code that couldnt find the object because the tag waasnt on it, so i guess that is why it would pause

i dont know why it likje actually clicked the pause button and not freeze

[swift epoch]

It's default behaviour to pause on any error so you can inspect and debug when it occurs. You can turn it off in console window

[weak talon]

its annoying because it was working and now suddenly not

[slender nymph]

you have error pause enabled. when an exception is thrown the game will pause. this helps you inspect what is happening at the time an error happens

you should ideally leave it on and stop ignoring the errors that appear in your console

[weak talon]

ok yeah i fixed, just needed to make an if statement to make sure it doesnt try and find an object when it doesnt need to

[peak python]

to make 2d ground fall when ground below is removed, i think there isn't a way to do it in ok way other than make a script that pushes squares down and checks for squares below it to make sure to stop when it hits them.
Make ground out of n columns each having k squares, make lowest square line as ground to ignore the script. Freeze x and z axis for 2d
need to make sure that another rigid body can drive on top of this
i guess no other way than i described?

like this

found a video that shows what i want
https://youtu.be/TSBcXoaV0o0?si=5yIkrcHKWrUda5ki

basically trying to recreate this but in unity and with movement 🙂

[rare basin]

how can I remove all bindings from a action (Submit action in my case), dynamically through code?

public class InputRebinder : MonoBehaviour
{
    public InputActionAsset inputActions;

    private void Start()
    {
        var uiMap = inputActions.FindActionMap("UI");
        var submitAction = uiMap.FindAction("Submit");

        submitAction.RemoveAllBindingOverrides();
    }
}

doesnt seem to work

[strong wren]

Check input rebinding samples. I believe you are supposed to change inputs with overrides. Removing all overrides would essentially be reverting to the "default". #🖱️┃input-system

[astral jungle]

Why my editor thingys are invisible , they were working just fine before

[slender nymph]

Not a code issue. Try either resetting your layout (not sure if this will work) or restart the editor

[peak python]

might tilemap help with my ground thing?

because now with rigid body and collider with discrete collision, some of the ground parts just go through other parts

and i feel that having like 4000 rigid bodies is kind of too much

[echo hamlet]

I am having problems with animations with a wolf asset I downloaded (already rigged and animated) and just copied most of the components from the character from the third person controller series.
The problem is that it seems to be stuck
The animation doesn't seem to be playing because the blend tree just causes it to change between the start of each individual animation.
https://drive.google.com/file/d/1CLuitZqQNqP03R6un2nHqJdk3RYE7Rno/view?usp=sharing

[swift crag]

Is "Loop Time" checked on the animations?

[swift crag]

there's the problem, yep

click on the model the animations came from, go to the Animation tab, and check "Loop Time" on each animation

[stuck palm]

@swift crag maybe the replay system should also replay the positions and velocities im storing? i feel like just inputs is not going to be enough at the moment.

[swift crag]

That would work, but it would prevent you from re-using the replay logic for multiplayer

[stuck palm]

because some bs keeps happening and like a single event i cant determine will throw the whole thing out of whack

[stuck palm]

how come?

[swift crag]

you want to be able to accurately re-create the same game state on both sides by just sending inputs back and forth

[stuck palm]

i see.

[swift crag]

Sending positions and velocities over would mean that one player's game is controlling the other player's game

or...something like that

[swift crag]

One thing you could do is add more of these "hash checks"

[stuck palm]

i've been able to do it somewhat consistently, but some replays will just go completely out of whack after like one thing and i dont understand why 😭 no errors or anything

[swift crag]

it won't be an error

[stuck palm]

i know

[swift crag]

it'll be something you did that is non-deterministic

[stuck palm]

im gonna have to look through all my shit and see what causes it

i have a video recorder that starts directly at the frame of starting and ends right as it ends, so i'll probably have to comb through some footage to see whats causing it.

[swift crag]

It could be that you're using RNG non-deterministically (how silly)

Unity may be using RNG for things like post-processing, for example

which would be framerate dependent

[stuck palm]

what about that seed thing you recommended?

[swift crag]

I think you're going to need to create your own RNG that's used strictly for gameplay

You also want to use a consistent RNG seed on both sides, yes

[stuck palm]

hm okay

[swift crag]

You can create a System.Random and store it in a static field

or use Unity.Mathematics.Random, which is a little closer to the UnityEngine.Random that you're used to

[stuck palm]

unity.random and unity.maths.random are not linked in any way im guessing?

is there anyway to get like a callback or something whenever random is used?

[swift crag]

No.

[stuck palm]

zamn

[swift crag]

You create an instance of Unity.Mathematics.Random. It's not static

The problem with UnityEngine.Random is that there's a single static RNG state

You can save the current state, restore a different state, do some RNG calls, and then put the original state back

But that's a bit of a nuisance

[swift crag]

By the way, if you're up to try to do rollback, you will need a way to serialize and deserialize your current game state (and QUICKLY!)

[astral falcon]

Arent the random values always the same depending on the seed?

[swift crag]

Right.

[ruby python]

Hi all, really quick Scriptable Object question. Is it generally considered 'good practice' to use an SO to store data to persist data between scenes?

[swift crag]

The problem is that everyone uses the same global RNG state with UnityEngine.Random, so other code can interfere with your RNG state

[stuck palm]

the only time i use Random in my character script is for shaking the mesh when you get hit, and playing different sounds.

[swift crag]

It's a hack that can blow up in your face if done incorrectly!

The trouble is that, like all other Unity objects, ScriptableObjects get unloaded if nothing is referencing them

this happens on scene changes

So if you write a value into an object and then change scenes, and nothing in the new scene references that object, the object gets unloaded

when you come back to a scene that does reference the object, it gets loaded again, and your changes are gone

[swift crag]

If it's purely cosmetic stuff, then that should be fine

[astral falcon]

As long as you do not save and restore the SO state, it will always RESET on runtime. Do not expect the editor behaviour on runtime

[ruby python]

Aaah okay, I get you. Was just thinking simple data, mainly level name/value that gets chosen in the main menu when starting up a game.

[swift crag]

Just stick it in a static field or on a DontDestroyOnLoad'd object

[swift crag]

The general idea is that:

• Every frame, you serialize the game state
• When you need to roll back, you deserialize an old state, then replay inputs

[stuck palm]

still worth a try i guess, maybe the matchmanager would create an instance or something that gets passed to the characters?

[swift crag]

This is one hell of a "general idea" here

[swift crag]

Both sides should be given the same seed on game start

[stuck palm]

yeah. annoyingly mathematics.random doesnt have insideunitcircle

[ruby python]

Okeydoke. 🙂 Thanks. Learning SO's atm so figured it was worth an ask 🙂

        mainCamera = Camera.main;            
    }

    private void Update()
    {
        
        foreach (var pos in tilemap.cellBounds.allPositionsWithin)
        {
            Vector3Int localPlace = new Vector3Int(pos.x, pos.y, pos.z);
            Vector3 place = tilemap.CellToWorld(localPlace);

            
            TileBase currentTile = tilemap.GetTile(localPlace);

            
            if (currentTile == null)
            {
                continue;
            }

           
            Vector3 targetPosition = place + moveDirection;

            
            Vector3Int tilePositionBelow = tilemap.WorldToCell(targetPosition + Vector3.down);
            if (tilemap.HasTile(tilePositionBelow))
            {
                continue; // Skip this tile if there is a tile below
            }

            
            Vector3 viewportPos = mainCamera.WorldToViewportPoint(targetPosition);
            if (viewportPos.y < 0 || viewportPos.y > 1)
            {
                continue; // Skip this tile if it would go outside camera view
            }

            
            tilemap.SetTile(localPlace, null); // Clear the current tile
            tilemap.SetTile(tilePositionBelow, currentTile); // Move the tile down
        }
    }
}

i have this code that puts tile down when there are no non null tiles below it or if it is withing camera view
the thing is, it works for some tiles and doesn't for for others
my tiles are colored so there is no hidden tiles below the colored, thus i am not sure why this applies only for some tiles

and some tiles even go below the camera view

[polar acorn]

@faint lark moving here since it seems to be code related.

Do you have multiple instances of the Character class? Maybe any added at runtime that aren't in the scene to start?

[peak python]

and this is how the tile started

[faint lark]

character class is a SO and all Character SOs have stats

so i dont understand why

[polar acorn]

The inspector will create a new stats class when you click on one if it's null. If you create a new Character instance outside of the inspector, stats never gets set to anything. You need to ensure that you are always setting stats to something upon creation, either by giving it a default value in code, or by having whatever creates the instance set it immediately after creation

[peak python]

is it because my code updates it without any delays? is this the case why tiles are not behaving like specified in code?

[faint lark]

problem was that a prefab that needs Character class SO didnt have one

thanks for the help

[languid spire]

Do you mean you have Domain Reload turned off?

[peak python]

I don’t turn it off or on
The only thing I did was switch the target to iOS and I think that is all o changed in project settings
Everything else is the default 2d project you get from unity

[languid spire]

then I don't get what you mean by 'my code updates it without any delays'

[peak python]

Like
Maybe it is so fast that some updates are ignored?

I just don’t understand why some tiles overshoot and some undershoot when it comes to the falling down

Since they all are under the same logic of the script

I move them down by the y equals to the grid size

[languid spire]

Then you need to Debug your script

[stuck palm]

GameManager.Instance.RNG = new Random((uint)replay.randomSeed);

I'm trying to create a random with a seed that's grabbed from a json. why is the state different from the seed that is grabbed?

[swift crag]

If you've queried the RNG for a value, the state will change.

[ionic zephyr]

is it okay if I reuse the script of my inventory slots to create crafting slots or might it be really confusing?

[modest dust]

Depending on your slots implementation, it might be completely reasonable to do so

[ionic zephyr]

the inventory slots are the ones that keep track of what you have but for example have a max quantity of 30 items in each slot

[ionic zephyr]

however, the crafting items can only hold a quantity of 1 item per slot

think of Minecraft for example

those types of slots should be different scripts/classes?

[modest dust]

Then introduce a variable for a max stack size in your slot script if you haven't done it already

[ionic zephyr]

okay, thanks a lot!

[modest dust]

Not really, a slot is a slot - it holds a certain amount of an item. It doesn't necessarily need to know what owns the slot and how it's used, that's the job of another script which simply uses the slot for it's own purposes

[swift crag]

You could define the "max capacity" in terms of both the number of items and in terms of a percent of the normal max stack size

that would be useful in many places

a crafting item slot can only ever hold 1 item

a small pouch can hold 1/2 of a normal stack

etc.

[stuck palm]

I'm confused, has the original seed not been used?

[swift crag]

I don’t know what your code is doing elsewhere :p

If you haven’t used the rng yet, then it should have the same state as the seed

[fringe kite]

why even if a raycast length is 0, this:

private bool IsGrounded() => Physics.Raycast(feets.position, Vector3.down, 0f);

still returns true and behaviours so weird

and when i test it on base colliders, like capsule, sphere, cube, this works perfectly, but with mesh collider doesnt

[stuck palm]

Come to think of it in the same frame there are other queries so that probably changes the state. I've tested multiple times and it always ends up at that numby

[swift crag]

That's expected, then

Each time you query the RNG, its state updates.

[stuck palm]

Ah I didn't know that, I thought the state stayed the same

I'm assuming if it stays the same then I'll just get the same number every time

[swift crag]

Exactly

The state is the only thing that affects what the RNG gives you

Nothing else matters

Hence it being the “state”

Your game also has a “state” — it’s just more complicated than one number!

can I ask a quick question about github here or should I join a dedicated github discord? it is somewhat related to unity

[hallow iris]

https://gdl.space/ocaqahetuf.cs detection script it is not properly working
https://gdl.space/cafoyidivo.cpp this is also not properly spawning bullets

i am trying to spawn bullets on a like 2d tile map within the fov in which the enimies are in but it is not working i have been trying for 6 hours to make this work please help

[heavy kite]

https://gdl.space/kegohitosa.cpp ,it makes me this error me this error "DialogueManager.cs(11,13): error CS0246: The type or name 'Actors' could not be found (are you missing a using directive or an assembly reference?
the only problem is that i don't understand why it makes me this error, i have rescerch but didn't find anything, it's a scrip which is normaly designed to create dialogue and work with an other script.
https://gdl.space/ejovijoloq.cs, this is the other script

[dense crater]

Hi I have a quick question, I’m trying to load a scene from assets in the editor but I can’t seem to find the right function to get all scene assets in a folder. Can someone point me in the right direction?

[swift crag]

Check AssetDatabase.FindAssets.

[heavy kite]

have you put your scene in the build ?

[swift crag]

I should ask why you're trying to do this, though

[dense crater]

I’m writing something that will only run in the editor

[atomic bison]

there is no channel for asking about unity and google play billing 6 right?

[swift crag]

sounds like #📱┃mobile or #archived-unity-gaming-services

actually, the former

[dense crater]

I’ll try this out, I tried it a bit ago but only could get garbage out for some reason. Hopefully I was just doing something wrong lol

[swift crag]

this is about Google Play billing, not about a specific unity payment service

[swift crag]

It gives you GUIDs. You have to load the individual assets.

foreach (var guid in AssetDatabase.FindAssets("t:Sprite ", new string[] { spritePath }))
{
    var info = new IconInfo() {
        sprite = AssetDatabase.LoadAssetAtPath<Sprite>(AssetDatabase.GUIDToAssetPath(guid)),
        color = false,
        outline = false
    };
}

e.g.

[dense crater]

Oh that makes sense! Thank you!

[remote lynx]

whats wrong with the bullets?

[hallow iris]

they do not move

[remote lynx]

how do you move them?

it doesnt move them in the script

[hallow iris]

rb = GetComponent<Rigidbody2D>();
enemy = GameObject.FindGameObjectWithTag("Enemy");

 Vector3 direction = enemy.transform.position - transform.position;
 rb.velocity = direction.normalized * force;

float rot = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;
transform.rotation = Quaternion.Euler(0f, 0f, rot + 90f);
this is on the FOV code

also cant join this to the fov for some reason

[remote lynx]

ohh

you move them in the other class?

[hallow iris]

i move them in the other script

[remote lynx]

is your bullet's rigidbody kinematic?

[hallow iris]

rigidbody 2d

[summer stump]

But is it kinematic?

[hallow iris]

i am new to coding in unity so i dont get much i got this code from a tutorial

[polar acorn]

Do you have a class named Actors

[hallow iris]

with this code i was basically trying to set a Fov of 180 degree when a enemy would walk in that fov that turret would shoot the most closest enemy

but it is not working

idk why

[heavy kite]

yes it's in thi script https://gdl.space/uhajuhutej.cs

[summer stump]

Look at the rigidbody. Does it have the word kinematic as the type?

[summer stump]

That is a nested class

You need to access it though the other class. OR just not nest the class

[remote lynx]

You sure that the raycast does ignore the enemy?

[heavy kite]

wich mean (sorry i started like one mounth ago so i don't really understand evrything)

[remote lynx]

the bullet has the turretScript attached to it right?

[polar acorn]

You would either want to take the class and define it outside of DialogueTrigger or access it with DialogueTrigger.Actors

[summer stump]

Your Actors class is inside the DialogueTrigger class

[hallow iris]

yes

[summer stump]

#💻┃code-beginner message

[remote lynx]

it probably doesnt have to do anything with the kinematic

[heavy kite]

so to use it i have to definde the class actor in DialogueManager

[summer stump]

Eh, I came in late. You asked so I was just trying to get the answer

[polar acorn]

It is currently in DialogueManager

[summer stump]

Just make it NOT inside a class

[polar acorn]

If you want to reference it you need to either move it out of there or use DialogueManager to access it

[heavy kite]

hoooooo

[polar acorn]

#💻┃code-beginner message

[heavy kite]

ok i understand now

[remote lynx]

@hallow iris why do you check the fov tho?

you set the velocity on start

btw you can simplify the FOV method into this```c#
private void FOV(){
Collider2D[] rangeCheck = Physics2D.OverlapCircleAll(transform.position, radius, targetLayer);
CanSeePlayer = false;
if (rangeCheck.Length > 0){
Transform target = rangeCheck[0].transform;
Vector2 directionToTarget = (target.position - transform.position).normalized;
if (Vector2.Angle(transform.right, directionToTarget) < angle / 2){
float distanceToTarget = Vector2.Distance(transform.position, target.position);

            if (!Physics2D.Raycast(transform.position, directionToTarget, distanceToTarget, obstructionLayer)){
                CanSeePlayer = true;
            }
            
        }
    }
}

[hallow iris]

i need a FOV for the turret so it would only shoot the enemy in range

[hallow iris]

thanks for the code

[remote lynx]

you said that the bullet has this script attached?

[hallow iris]

yes

[remote lynx]

it is attached to turret or the bullet?

[hallow iris]

both

[remote lynx]

oh thats weird

[hexed terrace]

The bullet should just have a script which moves it forward.
The turret should spawn the bullets facing the correct direction.

[remote lynx]

you should create different scripts

btw your turret has rigidbody?

[hallow iris]

yes

[remote lynx]

i gotta finish my project rn

can you do the thing Carwash said?

[hallow iris]

i cant try to seaprate both

[remote lynx]

why?

[hallow iris]

i am seaprating the spawning from movement

this happend

my transform for spawn area also moved

[remote lynx]

the spawn area has the turretscript right?

[hallow iris]

yes

[remote lynx]

it has rigidbody too right?

[hallow iris]

right

[remote lynx]

well you move the rigidbody of it in the turretScript

if you havent changed it

look at the Start method

[hallow iris]

it is ok when i freeze the x y and Z position

[remote lynx]

yes

because that way the rigidbody doesnt move

btw you have only 1 enemy in your world?

[hallow iris]

no multiple

there are slimes wolves and worms

i will add more

ngl i think i have botherd you too much

sorry for that

[remote lynx]

no problem

[hallow iris]

i think i am going to head off and reast my head for today

i have been working on the project for 12hours now

my thinking capacity has dimished

thanks for all of your help

[remote lynx]

wow

thats a lot

[hallow iris]

i love it it is addicting

i tried making a random ememy spawn system

it works

[remote lynx]

nice

[hallow iris]

but it is a bit wonky

[remote lynx]

ok

bye

[spiral path]

https://gdl.space/raw/udomilopiz

there you go

[remote lynx]

rb.velocity = Input.GetAxis("Vertical")

[spiral path]

that is what i have

[spiral path]

ok

[hexed terrace]

Where did you get this code from?

[spiral path]

unity docs

[remote lynx]

moving = Input.GetAxis("Vertical") != 0;

it should work now

[spiral path]

ok

[spiral path]

it says vertical does not exist

[remote lynx]

edit -> project settings -> axes

there should be vertical there

if there isnt reset it from here

[spiral path]

ok

[remote lynx]

it may be case-sensitive btw

first letter is upper case

[spiral path]

ok it is

https://gdl.space/raw/elipezuxef

new code still not working i think im doing something wrong

[remote lynx]

add rigidbody2d from the inspector

and do only rb= GetComponent<Rigidbody2D>()

dont forget to set isKinematic to true in the inspector

[remote lynx]

it should work tho

[spiral path]

ok

[remote lynx]

u sure you are using the up and the down arrow keys?

and not w-s

to control it?

[spiral path]

ok

[polar acorn]

A Kinematic rigidbody does not respond to forces, so you cannot move it by setting the velocity

[swift crag]

I believe that works in 2D

[remote lynx]

i think you can

[keen dew]

Input.GetAxis(Vertical) 🤔

[swift crag]

where is "Vertical" even coming from?

I see no such variable.

[polar acorn]

Man I just keep stepping on that rake of assuming 2D and 3D rigidbodies behave the same. One of these days I'm gonna need to actually make a 2D game

Just so I stop doing that

[swift crag]

the really weird part is that you have static, dynamic, and kinematic rigidbodies

[remote lynx]

you forgot double quotes brother

[summer stump]

You cannot. Kinematic rigidbodies can work with MovePosition though forgot it was 2d

[swift crag]

"not working" is extremely vague

if you're getting a compile error, say that

[swift crag]

This is a 2D rigidbody.

I just tested it. Works fine.

this cube is on the move

look at him go!

i have no idea where those measurements came from

i'm interested in that now, actually..

it's showing me the size of the world-space bounding box for the selected object (if it has a renderer on it)

[summer stump]

Ah 2d. Yeah, I did see that way earlier

Honestly, that is one of the weirder differences between 2d and 3d imo

[ruby python]

Evenin' all. Would someone mind taking a look at the following code please?

I'm having a weird issue where my Shockwave gets spawned twice from my pool, but only one of the two that spawn 'trigger' the ShockwaveController script (Attached to the Shockwave), so it never 'despawns'. I'm a little confused as to what I'm doing wrong and why two Shockwaves are spawning on 'DoEnemyDeath();.

https://hastebin.com/share/juderoziwo.csharp

(I know the code is a little messy and I need to move the explosion stuff over to a pool.)

[wintry quarry]

What is calling DoEnemyDeath? Isn't that the most important question?

[ruby python]

Ah my bad, one sec.

private void Update()
{
    if(enemyScript.enemyCurrentHealth <= 0)
    {
        DoEnemyDeath();
    }
}

    void DoEnemyDeath()
    {
        ExplosionSpawn(transform.position, 1f, "Death");

        // Add in Chance Check
        PowerUpDrop();
    }

    public void BulletImpact (Vector3 bulletPosition)
    {
        ExplosionSpawn(bulletPosition, 0.35f, "NotDeath");
    }

[wintry quarry]

private void Update()
{
    if(enemyScript.enemyCurrentHealth <= 0)
    {
        DoEnemyDeath();
    }
}```
Well this is going to run every frame, no?

It's pretty weird and inefficient to do such a check in Update

That's the kind of thing you should do at the moment the enemy takes damage

[ruby python]

That's temporary, like I said I know the code is a mess.

[rich adder]

that might help deal with the issue though

[ruby python]

Yeah I will be reworking the code quite a bit, but just solved the issue. I had the assigning/spawning etc. of the shockwave outside of the if statement.

[stuck palm]

@swift crag just realised, maybe its because some of my movement code is running in update could be ruining the determinism because of frame rate? updating the velocity vector is multiplied by deltaTime, though, so it should be fine? is there a difference between running it in update vs fixed update for deltatime?

[swift crag]

Yes. You can't do anything that depends on your framerate.

You need to do everything on a fixed cadence. You can still update visuals, play sounds, etc. in Update

[mild onyx]

i dont understand, his moves mine doesnt and he never says what buttons are causing the movement, i copied it exactly

this is to move a 2d sprite

[stuck palm]

even if im using time.deltatime?

[swift crag]

Yes.

[stuck palm]

i see, i'll change that immediately then

[swift crag]

imagine player 1 is running at 51 FPS and player 2 is running at 49 FPS

player 1 gets two frames before the next physics update

player 2 only gets one

[stuck palm]

i see. thanks! i think i didn't understand the purpose of deltatime, i thought it was something you'd use to get a similar effect to running it on fixed update

[mild onyx]

ignore my question, i made a spelling mistake

[swift crag]

It lets you calculate the amount to change something by each frame

And it does make your game's overall behavior framerate-independent

[polar acorn]

"I did it exactly like the tutorial so why does theirs work and mine doesn't" counter:
Number of times it wasn't exactly like the tutorial: 165
Number of times it was exactly like the tutorial: 5
Number of times the code literally did not exist: 1
2022-07-19 to 2024-06-25

[swift crag]

But that doesn't mean that your framerate doesn't matter

If your game needs to be deterministic, then you must update it with a consistent timestep

[mild onyx]

hey 😦

[summer stump]

You should not move the transform if you are planning on using a rigidbody.

[mild onyx]

why?

isnt rigid body just gravity?

[swift crag]

It's much more than that.

[summer stump]

Transform movement is the same as teleporting, and rigidbodies are affected by forces, teleporting will mess up the physics.

No, it is not just gravity at all

[swift crag]

a Rigidbody tells the physics system that this object is going to move around and be affected by forces

If you just set the transform's position, the physics system will discover that the object has teleported (for no apparent reason)

[mild onyx]

transform and vector are the only 2 methods im aware of

[summer stump]

Neither of those are methods

[mild onyx]

both moved the sprite

[summer stump]

One is a class and the other is a struct

Translate is a method though

You would USE a vector in rigidbody movement too

Look into MovePosition, AddForce, and .velocity

[mild onyx]

you know what i meant, i wasnt using coding speach when i said method

[summer stump]

I truly did not know what you meant.

[mild onyx]

velocity caused my sprite to roll like a ball, will the other 2 do that?

[summer stump]

Freeze the x and z rotation on the rigidbody

That way none of them will do that

Translate will cause that too if you bump into something and the physics engine actually manages to catch the collision despite teleporting

[mild onyx]

just seen that while testing it, i thought it was due to my oval hitbox rather than a rectangle

[summer stump]

Well, that IS part of it. But freezing the rotation on those axes will prevent it (unless you explicitly rotate them via code, which will still work)

In a physics simulation, round objects will certainly roll, so yes you are right about the cause

[mild onyx]

thanks

[dense root]

Do these two lines accomplish the same thing?

        if (other.gameObject.layer == LayerMask.NameToLayer("Player"))
        {
            hasEntered = true;
        }

        if (collision.gameObject.layer == LayerMask.NameToLayer("Player"))
        {
            hasEntered = true;
        }

[summer stump]

Looks like you just changed the name of the local variable?

If you didn't change the parameter name, then one of the two will be a compile error
But yeah, the compiler doesn't care what name you call it as long as it matches the declaration (and it is not a reserved keyword that isn't handled properly)

[dense root]

Oh okay, yeah I am using both in the same script

[summer stump]

Well, what is collision and what is other?

[dense root]

Oh, so yeah they do the same thing

I just need to be more consistent with my naming

[summer stump]

Yeah. What you're doing is completely fine in terms of the compiler. Consistency would be nice, but it's whatever for something like this hahah

Then name collision is usually used for the OnCollisionEnter method which passes a struct called Collision2D though. But yeah, it's local, it won't affect anything else

[dense root]

Awesome, thank you so much

[sharp abyss]

Anybody know how can I make a stake gun like in painkiller that pins enemies to the wall?

[rich adder]

ragdoll

then add some simple joints, set the anchor pos to be the raycast point

[dense root]

What's causing my spite image to swap out on start? The only script attached to it doesn't swap out sprites, what could be the cause?
https://gdl.space/muyuyolezo.cs

[long jacinth]

            other.gameObject.GetComponent<SpriteRenderer>().sprite =  playerWeapon.sprite;```

how can i do this?

like switch the properties of the two variable

[mild onyx]

i copied my jump code and edited for my positive horizontal movement and got this: if (Input.GetKeyDown(KeyCode.RightArrow) == true)
{
myRigidbody.velocity = Vector2.right * 10;
}

it doesnt work and just cancels my jump

[polar acorn]

Some code somewhere is changing the sprite. It doesn't just change on its own

[bleak glacier]

Any reason why this coroutine wouldn't be stopping? ```void Update()
{
Vector2 inputVector = new Vector2(Input.GetAxis("Horizontal"), Input.GetAxis("Vertical"));
rb.velocity = inputVector * speed;

  if (Input.GetKeyDown("left shift"))
  {
    speed = speed + 1;
    StartCoroutine(subtractEnergy());
  }
  
  if (Input.GetKeyUp("left shift"))
  {
    speed = speed - 1;
    StopCoroutine(subtractEnergy());
  }
}
          IEnumerator subtractEnergy()
    {
        for(;;)
        {
        energy = energy - 1;
        yield return new WaitForSeconds(1f);
        }
    
    } ```

[polar acorn]

You're setting the value directly to a value, which is overwriting whatever it was before. If you want the jump to work you probably need to keep the Y value the same

[dense root]

Yeah i discovered the cause, it was from the darn animator I duplicated it from

[mild onyx]

i thought it wouldve just worked out the resultant force, i guess not

[outer solar]

Im following a tutorial to make a car but my wheels just rotate by 90° when i start the game.
can anyone help me fix that?

thats the part of the code for the Wheels:
private void UpdateSingleWheel(WheelCollider wheelCollider, Transform wheelTransform)
{
Vector3 pos;
Quaternion rot;
wheelCollider.GetWorldPose(out pos, out rot);
wheelTransform.rotation = rot;
wheelTransform.position = pos;
}

[rich adder]

looks like you linked the wrong tires 🤷‍♂️

share the full script we might be able to help out more. Wouldn't hurt to share video as wel

[outer solar]

i have already followed a different tut but had the same issues.
I mean it works like it should but the wheels just rotate in the wrong directions

[rich adder]

then you linked your objects wrong

have probably incorrect pivot

how else we supposed to know whats wrong with that snippet alone

[rich adder]

show all the gizmos for the wheels

in pivot / local mode

[raw token]

If you're directly managing velocity, forces don't really come into play unless you do the math yourself - and any forces applied via AddForce() will also be nullified. That said, if you just want to add the velocity to what's already there, it's just a matter of changing your = to +=

[rich adder]

show the gizmos for each wheel, show the entire scene view so I can seee if~~ gizmos are on Local~~ ok its local since the X pointing down

also you have still Center mode on though

[outer solar]

the wheels are all rotatet like they should as far as i know

[mild onyx]

oh yeah, any ideas on how to click between two letters of code? currently i cant add a letter without having to rewrite everything after

[polar acorn]

press insert

[swift crag]

Show us the inspector for one wheel

It looks like the wheels are starting with a 90 degree Y-axis rotation

[neon ivy]

I'm trying to set a bool to true when a microphone is hearing something. but there's no such feature in the Microphone class. anyone know how to do this?

[swift crag]

Now show the wheel collider's inspector

It looks like you have a 90 degree offset between the two

[swift crag]

yep

Notice how the blue arrow points in different directions

When you copy the world-space rotation of the collider onto the wheel, the blue arrows are aligned

[outer solar]

yeah but when i set the rotation to 0 they stay rotated like that

the colliders dont rotate just the model

[swift crag]

There are two options here

[swift crag]

private void UpdateSingleWheel(WheelCollider wheelCollider, Transform wheelTransform)
{
    Vector3 pos;
    Quaternion rot;
    wheelCollider.GetWorldPose(out pos, out rot);
    wheelTransform.rotation = rot;
    wheelTransform.position = pos;
}

You can combine the rotation you get from GetWorldPose with the original rotation of the wheel

So, you'd do something like this:

wheelTransform.localRotation = Quaternion.AngleAxis(-90, Vector3.up);
wheelTransform.rotation *= rot;

This will set the wheels' rotation back to how it started, then apply the wheel collider's rotation on top of that

The second option would be to just parent each wheel to an empty object.

Set the rotation of the empty object.

• Car
  • Empty <-- rotation of [0,0,0]
    • Wheel Model <-- rotation of [0,-90,0]

This is an easy way to deal with a model that needs an odd position, rotation, or scale

You get it lined up properly beneath the empty object. Now you can just move that empty around however you want.

[outer solar]

Yeah that worked

Thanks a lot!

[swift crag]

np!

[swift crag]

this is what I'd do if I absolutely had to maintain the current hierarchy

but otherwise, it's easier to just line your models up properly

[onyx tide]

Hello i'm new on unity. It is good to use the package "Input System" for the main character ? I don't found a lot of tutorial with this

[wintry quarry]

If you're a beginner it's better to stick with the old input system as it is easier to learn

[magic panther]

I'm curious. Why does an arrow work for the player here but not an equals sign like above for the moveDir?

[wintry quarry]

these are two different things entirely.

the top one is a field with a field initializer.
The bottom one is defining a property with only a get function, and is defined as an expression-bodied member, returning this

[swift crag]

you can't initialize a field with another field or property

actually, what is this?

it's kind of a member, but not really

either way, you are not allowed to look at yourself in field initializers

public int x = y;
public int y = x;

imagine the pandemonium

[magic panther]

I think I get it

[swift crag]

private Player player = null;

This would be fine.

[wintry quarry]

the bottom one is a shorthand way of doing this really:

private Player GetPlayer() {
  return this;
}```

[magic panther]

so can I jsut write this instead of creating a player and using it?

[wintry quarry]

Yes there's no reason for that property to exist, you can just use this

[swift crag]

this is kind of a chicken and egg problem

"instead of creating a Player"

this is part of the Player class!

[magic panther]

this.transform.position += new Vector3(moveDir.x, moveDir.y, 0f); should work if I understand you guys correctly

[polar acorn]

Yes, and it's identical to transform.position += new Vector3(moveDir.x, moveDir.y, 0f)

[wintry quarry]

yes but you don't need this most of the time

[swift crag]

It's implicitly added when you use a name that isn't a local variable.

int x = 123;
this.x = x;

it is mandatory when that's the case

this creates a local variable called x that contains the value 123, then writes it into a field called x

public class Foo {
  public int x;

  public void Something() {
    int x = 123;
    this.x = x;
  }
}

e.g.

[ionic zephyr]

does anyone know how to put an item into the crafting slot by cliking on it like in this example?

[rich adder]

just parent it to the transform, reset the localPos

[ionic zephyr]

I have a slot prefab so it is not about moving it to that area physically

[bold plover]

So I don't mess up my files while reorganizing, do I change the file name in my Unity program or in my IDE instead? Or both simulatenously? I'm worried if I do one over another or out of order it will break my references.

[rich adder]

then what are you asking ?

[ionic zephyr]

the thing is there are inventory slots and crafting slots

think of Minecraft for example

[fringe kite]

ples help

[bold plover]

Is it possible the raycast you are using is not checking for the parent object while being inside the center?

[ionic zephyr]

without drag and dropping, only by clicking, I want to pass the materials to the crafting station and depending on what I´ve introduced, it crafts something

[fringe kite]

feets not in the player model center

[bold plover]

That's strange. What are you trying to use the raycast for specifically? That will help better figure out the issue.

If the feet are making contact with the ground then even with a distance of zero it's possible it's still returning true because of direct contact.

[rich adder]

so define a class named slot and add the clicking behavior

[fringe kite]

i use it to detect if player grounded at this moment or no

[ionic zephyr]

okay, let me see

[fringe kite]

in my happening raycast detects ground until 53 pos at y

mystics

[raw token]

I think it's fine to change the filename in either location, if your IDE is properly configured for Unity... Or at least I know that in least Visual Studio it's capable of updating the metadata file as well (which is the crux of maintaining your references), but I can't speak for other editors

[bold plover]

Ok cool. I'll do a backup anyway but just wanted to double check.

[bold plover]

I'm not really sure then. Sorry boss.

[bold plover]

Awesome. Thanks again! Just a bit paranoid because of flashbacks. Some of my code relies on checking for materials and my friend who is doing the art updated some a while back and that broke a few things.

[fringe kite]

see

idk how to fix it

really

[queen adder]

new to unity, following tutorial, not working, what is wrong with my declaration (3D rigidbody)?

Rigidbody rb; rb = GetComponent<RigidBody>();

[polar acorn]

what isn't working

[queen adder]

"Rigidbody cannot be found" CS0246

[slender nymph]

spell it right

[polar acorn]

Look at the thing underlined in red in your IDE and see what's wrong with it

[frosty hound]

That alone isn't valid code either, but assuming you've just copied out what you think is the issue: Rigidbody is not the same as RigidBody:
https://docs.unity3d.com/ScriptReference/Rigidbody.html

[bold plover]

Syntax strikes again.

it do be like that

[fringe kite]

are you using UnityEngine; and your script is child of monobehaviour?

[fringe kite]

ah

[queen adder]

article doesn't specify the syntax.

Tutorial is using "Rigidbody2D".

[swift crag]

show us the tutorial.

[queen adder]

https://www.youtube.com/watch?v=c9kxUvCKhwQ 3:14

[bold plover]

Yeah it's probably just the capitalization of the "b".

[polar acorn]

It does specify the syntax in the fact that it shows you how to spell the word right there

[frosty hound]

Syntax is how you spell something, the link I gave you spells it.

[swift crag]

🤓 actually

[queen adder]

Yes, I am using 3D

[swift crag]

this is not a syntax error

[stuck palm]

@swift crag strangely enough sometimes replays work absolutely frame perfectly (overlaid a recording of the original and the replay and there was no weird overlap) and sometimes they dont work as well. i've only been able to record 1 player moving at a time so far

[polar acorn]

Correct. And you have to spell it right

[swift crag]

the syntax of C# is its grammar; a bogus name is not a syntax error

it does fail to compile when the compiler tries to figure out what that name means, though

[queen adder]

in the tutorial he spells it wrong, so whoops haha

[bold plover]

<Rigidbody2D>

[polar acorn]

No he doesn't

[bold plover]

I don't think it matters. The issue was spotted.

So is it working now BIG?

[queen adder]

no hahaha

[swift crag]

well, it is good to recognize the error that was made...

instead of just asserting that the tutorial was wrong

[polar acorn]

"I did it exactly like the tutorial so why does theirs work and mine doesn't" counter:
Number of times it wasn't exactly like the tutorial: 166
Number of times it was exactly like the tutorial: 5
Number of times the code literally did not exist: 1
2022-07-19 to 2024-06-25

[queen adder]

bruh is that first part a bot or something?

😂

[bold plover]

Didn't say it wasn't but no point getting hung up on that. It happens.

[queen adder]

bros keeping score, and I added to it

[swift crag]

That is the idea, yes.

[bold plover]

Sometimes you just need a second set of eyes.

[polar acorn]

No it's just the times I have personally been around when someone claims to have copied the tutorial exactly only to have not done that

[queen adder]

meh it happens

or maybe I just need to get gud

[rich adder]

or glasses

[queen adder]

I actually need glasses badly

being poor is sucks

so this should work then?

Rigidbody3D rb; rb = GetComponent<Rigidbody3D>();

[polar acorn]

Where did you find a class named Rigidbody3D

[queen adder]

I'm assuming its correcrt since it would be the 3D form of 2D

[rich adder]

so you're guessing?

this isn't a puzzle game

[polar acorn]

You were linked to what to use:
#💻┃code-beginner message

Why make up a class instead of using the one whose documentation you were sent

[raw token]

If your IDE is properly configured, it should be suggesting possible values, and highlighting things that are wrong

[bold plover]

True. Trust it helps.

[queen adder]

the documentation doesnt specify which one to use in 3D vs 2D

[bold plover]

When I started I didn't know you could configure and was just tabbing in and out of Unity.

[willow scroll]

I don't think there's a single Component in Unity, which uses 3D in its name. It's either ComponentName or ComponentName2D if it's 2D

[frosty hound]

The documentation is the 3D one

[bold plover]

Behold there was an easier way.

[polar acorn]

That's the name

You can look at the name and see the name of the thing

🤯

[bold plover]

I think it's 3D by default and you have to specifically specify 2D for 2D.

So just <Rigidbody>.

[queen adder]

as someone who started unity development literally 4 hours ago, I did not know this

[summer stump]

!learn

[eternal falcon]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[queen adder]

that's why I came here to ask, sorry if I haven't nailed down the naming conventions yet guys

[bold plover]

<Rigidbody3D> isn't needed.

[willow scroll]

That's what you should do before asking here

[spare mountain]

Rigidbody4D on the other hand... 😎

[bold plover]

In a beginner chat?

[willow scroll]

Yes.

[queen adder]

I created the exact project I am working on in Godot, I just switched to unity. I don't need to go throguh all those tutorials I just need a few pointers

[willow scroll]

Which tutorials can give you

[spare mountain]

this is not a "we will walk you through the basics of coding" this is a "you know how to code basic things but have a beginner question" channel

[bold plover]

I mean in the time it took you to link a bunch I just answered the question.

[queen adder]

or someone can just throw me a bone and save me dozens of minutes looking for a two second answer

[bold plover]

In a single line.

[summer stump]

Which is what we call spoonfeeding around here. It is discouraged

[swift crag]

perhaps you should consult #854851968446365696

[summer stump]

You should definitely do the course I linked above

[bold plover]

Catching a mispelling isn't spoonfeeding.

lol

[rich adder]

we call enablers

[spare mountain]

but now they're going to come back later and you're wasting your time

[bold plover]

You

Are the ones still @ing me about it.

but ok

[swift crag]

linking to documentation that tells you exactly what to do is a reasonable response #💻┃code-beginner message

[summer stump]

Directly answering is spoonfeeding. Encouraging them to look at the docs is not.

[bold plover]

I don't think saying "oh you mispelled something" is hand-holding.

[swift crag]

you want to encourage people to learn to solve problems

[swift crag]

i should point out that the answer was given almost immediately anyway

[queen adder]

the article linked did not specify it was specifically for 3D. I saw that article before I answered the question. Because I am not familiar with the Unity naming conventions, I assumed thaat since the tutorial was using Rigidbody2D, the 3D one would naturally (apparently not) be Rigidbody3D.

[rich adder]

its not an "Article" its literally the class for the 3d one

it tells you everything the class can do

[summer stump]

I strongly recommend against any tutorials on youtube. Do the learn course before anything else
#💻┃code-beginner message

[bold plover]

Explain to me how this helps build critical thought and I'll accept it. All I'm saying.

[willow scroll]

But you could've figured out that's not the case by looking at the syntax error it was throwing.
Also you've mentioned coming to Unity from Godot. I'm not sure, is Godot case insensitive if you think RigidBody is the same as Rigidbody?

[queen adder]

that was just another oversight

I wasn't even sure the 3D part was correct.

which it wasnt

[rich adder]

reading the api to learn how the class you want functions ?

what they learn if you do "do this , copy that"

[swift crag]

If you don't understand something about a resource, you should ask about it

"Is this the 3D rigidbody?"

whilst showing initiative is good in a sense, randomly guessing names isn't very useful

[bold plover]

It was a capitalization of the "b". It's not that deep.

[swift crag]

that was the original problem, followed by more problems.

[summer stump]

No one is saying that was an issue... simply pointing out a spelling error is not what is being called spoonfeeding
However, even then saying something like "consider the capitalization in the word" might have been more helpful in the long term, but that is whatever

[bold plover]

I did say to configure the IDE to catch issues like that. I'm sure that would be considered as a good piece of long term advice.

[neon ivy]

I copied this function from a youtube tutorial and tested it out but I'm getting an error message I do not understand...
code:

private void Update()

    if(GetLoudnessFromAudioClip(Microphone.GetPosition(device),micOutput) * 100 > micThreshold)
    {
        Debug.Log("Heard");
    }
}

    int startPosition = clipPosition - sampleWindow;
    float[] waveData = new float[sampleWindow];
    clip.GetData(waveData, startPosition);
    float loudness = 0;
    for(int i = 0; i < sampleWindow ; i++)
    {
        loudness += Mathf.Abs(waveData[i]);
    }
    return loudness / sampleWindow;
}
``` error:

UnityEngine.AudioClip:GetData (single[],int)```

[short hazel]

Seems like it comes from the C++ backend, and that the parameters for clip.GetData() aren't checked on the C# side...
Are you sure startPosition is in range of the clip, ie. not negative nor too large so it falls out of the clip data length?

The subtraction you're doing a few lines above could yield a negative number for example

[neon ivy]

oh...

yep that's it :I idk how the video didn't have that issue.

thanks

[stuck palm]

are rigidbodies deterministic?

[summer stump]

Dynamic ones? Definitely not.
Kinematic, depends on you

[swift crag]

shebb is embarking on the wild ride of a multiplayer fighting game

[ionic zephyr]

if I want to show in the slots of my crafting station the items I am placing is it better to instantiate an image in the slot transform?

[wintry quarry]

Would probably have Image components there already and just set the sprites as needed

[stoic spear]

i am once again going insane, there must be a good way to do this

[wintry quarry]

use a for loop

[ionic zephyr]

okay, I´ll try that

thanks!

[swift crag]

can't really do a for loop there

I guess you could if they're consecutive enum values

[stoic spear]

Input.inputString maybe?

[wintry quarry]

KeyCode[] hotbarKeys = new KeyCode[] { KeyCode.Alpha1, KeyCode.Alpha2, ... etc };

void Update() {
   for (int i = 0; i < hobarKeys.Length; i++) {
     if (Input.GetKeyDown(hotbarKeys[i]) && heldFirearms[i] != null) {
       ChangeFirearm(i);
     }
   }
}```

@stoic spear

[stoic spear]

clip it to only numerical values

[swift crag]

ah, there you go

good thought

[stoic spear]

oh, nice

[swift crag]

I was going to suggest something awful

for (int why = (int) KeyCode.Alpha1; why < (int) KeyCode.Alpha9; ++why)

[wintry quarry]

That's also an option

and probably works

[swift crag]

praetor's is much easier to grok

[wintry quarry]

But this is more configurable and yeah easier to explain

[swift crag]

also mine is wrong because it skips key code 9

Any idea
Why sound is not playing? When I collision occur

https://gdl.space/qawojetuta.cs

[rotund forum]

Hopefully this is a simple question to answer, but I was thinking about how I would handle damage done to enemy characters in my game.

The player can shoot bullet projectiles, and I was thinking of just giving separate colliders to the upper arms, lower arms, and etc. (specifically just for taking damage) of the enemy units so that one could aim and essentially shoot at the mesh of the enemy (as opposed to the capsule collider I have on them now so they don't fall through the ground).

Is this a solid way to do this or am I overcomplicating things?

[swift crag]

Sure, that sounds reasonable.

[west sonnet]

how can I change the size of a collider in script? I'm trying to do collider.size but it's not recognizing the .size

[swift crag]

I would create a Hurtbox component (or Hitbox -- "hurtbox" is more common in a fighting game where "hitbox" is used to attack)

[summer stump]

A sphere or circle collider takes radius. It depends on the shape

[swift crag]

It would specify how much it hurts to get hit in that spot

[swift crag]

Collider doesn't have a way to adjust the size

[west sonnet]

It's a rectangle

[swift crag]

because it's not specific enough

you need to know what kind of collider you have

[west sonnet]

Ooooh yeah, you're right

Thank you!

[swift crag]

if (!Physics.Raycast(shootPoint, shootDirection, out var hit, maxRange, hurtboxMask))
  return;

if (!hit.collider.TryGetComponent(out Hurtbox hurtbox)
  return;

hurtbox.owner.Hurt(100 * hurtbox.damageScale);

something like that

[summer stump]

Do you mean box or cube?

[west sonnet]

Box, 2D

[summer stump]

https://docs.unity3d.com/Manual/class-BoxCollider2D.html

[rotund forum]

Thanks. This is something along the lines of what I was thinking.

Just very doubtful of myself sometimes!

🙏

[stuck palm]

im making decent progress, i managed to play a 2 player game where all the inputs were perfectly recreated, i feel like im getting close to complete determinism

[magic panther]

apparently I'm doing something wrong

cinemachine is installed

[wintry quarry]

https://docs.unity3d.com/Packages/com.unity.cinemachine@3.1/api/index.html

The namespace of all the classes is listed on the left and on each page fpor each class.

hint: it's not Cinemachine

[magic panther]

the guy is using Cinemachine. Is this just outdated?

1 year old vid

[wintry quarry]

yes outdated

Your IDE should suggest the correct namespace for you

[magic panther]

it's not

[wintry quarry]

You may need to do "regenerate project files"

from the external tools menu

And yeah it depends which version of cinemachine you have

In 2.xx versions it's Cinemachine

In 3.xx it's Unity.Cinemachine

[magic panther]

also not that

where's the external tools?

[wintry quarry]

in preferences

(this is from my mac, windows may look slightly different)

[magic panther]

seems to work so far

it's no longer underlined

[lusty nest]

I have a prefab of a ragdoll and after the ragdoll has has been moved around, I would like to have a function that would be able to "restore" the ragdoll to the state it was in the prefab. Is there any simple way to do this ?

[eternal needle]

Write a script which stores the initial positions and rotations. Probably will need to set the velocity of everything to 0 as well if that's what you want

[stuck palm]

@swift crag I've come to the conclusion that framerate is still an issue for keeping my game deterministic, as well as dynamic rigidbody projectiles. for some reason, recording games using the recorder makes the framerate really low, but it also somehow has the added quirk of keeping the games without rigidbody projectile characters very in sync

lots to sort out clearly

[misty pecan]

private void Spawn(int level, int amount, float delay)
{
float spawnTimer = 0;

for (int enemiesSpawned = 0; enemiesSpawned < amount; enemiesSpawned++)
{
    while (spawnTimer < delay)
    {
        spawnTimer += Time.deltaTime;
    }

    Instantiate(enemyArray[level - 1], transform.position, transform.rotation);
}

}

why is this just spawning them all instantly???

[swift crag]

because this code, like all other code, doesn't take any in-engine time to run

https://docs.unity3d.com/Manual/Coroutines.html

this shows the exact problem you're having

[wintry quarry]

why wouldn't it

Age is just a number, and so is deltaTime. Using deltaTime doesn't magically cause time to elapse in game.

[ionic zephyr]

what can i do to make sure that whenever I stop using a crafting station but I haven´t crafted anything that my objects don´t get lost?

[wintry quarry]

That's a really vague question that depends heavily on how your entire crafting and inventory systems work.

[swift crag]

one option would be to have a method that runs as you close the crafting menu

it would attempt to move every item still in a crafting slot into the inventory of whoever was using it

and, failing that, turn them into drops that drop on the ground

[wintry quarry]

I mean realistically I would just leave the player's inventory alone entirely until they actually craft something.

I don't see why anything should change before actually crafting

[spiral raven]

Agreed. Items should only sit mirrored in a staging area but remain in inventory until the player commits to the craft.

[swift crag]

this is something like Mincraft's crafting table

which could make it more difficult to "reserve" items like that

[stoic spear]

slight problem, this throws index errors if i click a hotbar space that doesnt exist yet

[wintry quarry]

that's what if statements are for friend

[ionic zephyr]

Okay, I´ll try, thanks

[stoic spear]

if i > heldFirearms.Count-1 ?

[wintry quarry]

for (int i = 0; i < hobarKeys.Length && i < heldFireArms.Count; i++)```

would just update the for condition like this honestly

[ionic zephyr]

the thing is I am placing the objects right from my inventory into the table so the quantity lowers each time

I dont know how to create that staging area

[wintry quarry]

or do cs if (i >= heldFireArms.Count) { PlayNoItemSound(); break; }

if you want to like... let the player know with a sound or something

the world is your oyster

[stoic spear]

thats working great, thanks!

[misty pecan]

private void Spawn(int level, int amount, float delay)
{
for (int enemiesSpawned = 0; enemiesSpawned < amount; enemiesSpawned++)
{
StartCoroutine(WaitThenSpawn(level, delay));
}
}

IEnumerator WaitThenSpawn(int level, float delay)
{
    yield return new WaitForSeconds(delay);
    Instantiate(enemyArray[level - 1], transform.position, transform.rotation);
}

Why is this spawning them all at once?? It waits for the delay and then spawns the full amount at once, Why?

[swift crag]

StartCoroutine does not "delay" the method that called it

That would freeze your game.

You're starting many coroutines. They all wait for a delay, then spawn an enemy.

The page I linked you to shows you exactly how to perform the same action many times with a delay

IEnumerator Fade()
{
    Color c = renderer.material.color;
    for (float alpha = 1f; alpha >= 0; alpha -= 0.1f)
    {
        c.a = alpha;
        renderer.material.color = c;
        yield return new WaitForSeconds(.1f);
    }
}

[misty pecan]

It gives an error

[swift crag]

and what is the error?

[misty pecan]

Error (active) CS1624 The body of 'LevelManager.Spawn(int, int, float)' cannot be an iterator block because 'void' is not an iterator

Because voids dont return a value yes?

[swift crag]

You're trying to use yield return new WaitForSeconds(...) in your Spawn method

it's not a "void". It's a method whose return type is void

[swift crag]

You have to write a separate method that returns IEnumerator

(as you've already done)

[misty pecan]

ah

i think i get it now

just no coroutine this time?

[swift crag]

No. You need a coroutine.

[swift crag]

If you just ran Fade() in this example, nothing would happen

You have to pass the returned object to StartCoroutine.

[swift crag]

as you have already done

all you have to do is put the for loop in the IEnumerator method

[misty pecan]

will do

[uneven mulch]

Does anyone know the solution to this problem?
In the editor and all the UI works, but it doesn't in the build. Unity 2D

[swift crag]

what does "works" mean?

are you unable to click on anything?

[uneven mulch]

You can see it in the editor

But not in the build

[swift crag]

Try changing the resolution of the Game View

see if your UI moves around or disappears

Mhm

[uneven mulch]

Nope, doesn't work

[swift crag]

"Doesn't work?"

this isn't a "fix"

[uneven mulch]

You can't see it

[swift crag]

I'm asking you to change the resolution of the Game View and seeing what happens to the UI

This has no effect on the built game

[uneven mulch]

Oh

It does now

In the 4k view you can see it

In normal hd you cant

[swift crag]

You need to fix your anchors.

https://docs.unity3d.com/Packages/com.unity.ugui@1.0/manual/UIBasicLayout.html

You can read about how RectTransforms work here

the general idea is that, if something goes in the top left corner, it needs to be anchored to that corner

By default, everything is anchored to the center

This means that as the resolution changes, the position will change

if something is always 1000 pixels to the left of center, then it will fly off-screen at low resolutions

[uneven mulch]

yep

i fix it

now

[low hatch]

i need help, I can't add any references to this one script, not sure what i have done wrong

I cant drag anything into it either

[polar acorn]

Do you have anything with a Button component on it?

[low hatch]

wdym

[polar acorn]

You're trying to reference a Button. What Button

[summer stump]

See #854851968446365696
It explicitly lists wdym as something you should not respond with.

Do you not know what button is? Or was "on it" unclear? They mean attached to a gameobject.
We don't know what you know, so wdym is an unhelpful response

[low hatch]

ah ok

thanks for letting me know that

i should also be able to figure out the component reference

[vast vessel]

whats the issue here?

[swift crag]

look at the signature of EnumPopup

https://docs.unity3d.com/ScriptReference/EditorGUILayout.EnumPopup.html

it returns Enum

That's less specific than your exact enum type

You have to explicitly cast it back to the enum type you want

[stuck palm]

GameManager.Instance.RNG = new Random((uint)replay.randomSeed);

when i create an RNG, does it immediately change the seed after i do this?

[long jacinth]

playerWeapon.sprite = other.gameObject.GetComponent<SpriteRenderer>().sprite;
other.gameObject.GetComponent<SpriteRenderer>().sprite = playerWeapon.sprite;

How do i do this but with it actually working

[swift crag]

No. Nothing happens until you sample the RNG.

[swift crag]

well, you'll have to explain what the problem you're having is

"actually working"?

is there a compile error?

It looks like you want to swap the two sprites

[long jacinth]

i want to switch value because im making a weapon pickup system

[long jacinth]

yes

[swift crag]

Put the first sprite in a variable.

that way you can access it after you overwrite the player's weapon sprite

[stuck palm]

i see. could the changing of an unsigned int to a signed int possibly change the seed?

[long jacinth]

yo it works thanks

wait a second

nah its good

wait no this is weird

one second im gonna take time to think through this

[remote osprey]

hello

Can a child property have a way to know the identity of the scriptable object its a child of?

[cosmic dagger]

Not sure I understand? What are you trying to do?

[remote osprey]

I just needed a method that returns the parent from the child

[stuck palm]

really? i've got this replay system, and it seems like the rigidbodies follow the same path pretty consistently. the screenshot is two videos overlaid on top of each other, and they seem to be pixel perfect in terms of the path they follow.

[remote osprey]

I have a CardSO that houses an EventSO, I need to know the CardSO from EventSO

[cosmic dagger]

You mean from a GameObject?

[remote osprey]

Yeah, tbh I think I'm confused

I was making the same mistake again of forgetting i had passed my CardSO data to my CardData

[cosmic dagger]

Oh, okay. The parent/child is for a GameObject. You'd have to pass a reference to the EventSO . . .

[remote osprey]

Problem is i can't alter it runtime

Ok, so i'm in a pickle

I want to make a complex event system that goes as follows:

• Invoker deals x damage to Enemy Player
• Invoker deals x damage to Enemy Summon
• Invoker deals x damage to Enemies (Player and summons)
• Invoker deals x damage to Enemy Summons
• Invoker deals x damage to Random Enemy
• Invoker deals x damage to Summon
• Invoker deals x damage to Random Player
• etc...

But i don't want it to just be "deal x damage" it could also be apply "rot debuff"

[remote osprey]

So i have the CardSO and an Event SO, problem is it doenst have a target right away

And since its an SO, i can't modify iit runtime

I shouldn't be able to modify events anyway, since they represent commands.

So I need a way to know at runtime

1. who the target to the event is (if there is a need for a target)
2. what kind of target it is

I believe 2) would be achievable with a TargetGenerator abstract class

1. is what I can't get around, because I don't know to which card the event belongs to

[summer stump]

I do not know. I made an assumption. I would trust your testing over what I said.

[remote osprey]

Maybe i should also do an non SOEvent class just so i could pass the owner to it at run time

[mild onyx]

is there a way i could merge these two sections of code? movement direction requires both x and y however i dont want the w and s keys to do anything, just the space bar to do a simple jump

[rich adder]

Vector2 is 2 floats

you only passed 1

the name, vector2 🙂

[mild onyx]

so if i put vector 1 it will be fine?

[rich adder]

vector1 is just a float

[polar acorn]

Did you check if there is such a thing

[rich adder]

pulls out the ShaderGraphs stuff

good thing they renamed all the vector1s into floats lol

[strong wren]

how do i fix this error?

    {
        if (collision.gameObject.CompareTag("EnemySlap"))
        {
            S.Health -= 1;
        }
    }```

[rich adder]

make it not null

[strong wren]

this is the code related to the error

[polar acorn]

Take a look at the lines the errors are on, and find the thing that's null and make it not be that

[rich adder]

how do we know

[stuck palm]

as it turns out it is not deterministic lol, weirdly enough at full speed fps there are some issues, like sometimes it bounces off and sometimes it doesnt, but that doesnt seem to happen at a low fps, which happens while i'm using the unity recorder.

[polar acorn]

which line

[rich adder]

we can't read lines number from one snippet alone

[strong wren]

line 51

[rich adder]

lol

big brain reply

[strong wren]

which would be S.Health -= 1

[strong wren]

thanks

i know im smart

[rich adder]

so S is null

make it not be null

[polar acorn]

Cool and how am I supposed to know what that is from what you've posted

[raw token]

Those two things appear to be unrelated to eachother based on the code provided alone. Without knowing if and how movementDirection is related to the rb's velocity, it doesn't appear to be something you could combine

[polar acorn]

S is null

[strong wren]

oh so i didnt connect the thing

alright

i didnt select the gameobject with the sciript S

ye i found it

thanks yall

idk how yall put with me

i hate myself so it wouldnt be something rare for yall to hate me too

[rich adder]

lol just post code properly next time

[mild onyx]

i dont know how else to do movement, every tutorial seems to be flawed in some way and codes online are like 50 lines long and i dont understand a single line of it

[strong wren]

ok

[rich adder]

if you're gonna show us the line number send the whole script or just tells us which one is line 51

[strong wren]

i did that tho i said line 51 which would be then said the exact line

[rich adder]

you said After which one was line 51 😉
