C# is case sensitive

small zealot
#

yeah im looking for it

wintry quarry
#

I can see two right there

#
  1. delete the duplicate script
  2. Rename the movement class to Movement
  3. you should be able to assign it properly then

yeah it worked

thanks bro your my goat

#

I have an invisible unity sprite, no clue why its not showing up

image.png
#

camera z = -10
GameObject sprite z = 0

wintry quarry
#

instead of SpriteRenderer

#

Image is for UI

quick tundra
#

ah

wintry quarry
#

it also... has a RectTransform?

#

Meaning you put it on a canvas

#

so is this intended to be a UI element, or is it intended to be in the game world?

quick tundra
#

game world

#

i didnt put it in canvas tho

wintry quarry
#

ok well

#

i recommend remaking the object

#

with a SpriteRenderer component

quick tundra
#

thanks

#

it works!

hey, me again! im having trouble using shader graphs to implement into my game gerstner waves; i want them to move all over the place but they seem to only move back and forth (and not side to side). Does anybody have any ideas on how to fix it? I can send pics if needed

how do i fix this

wintry quarry

Write your code so it only uses variables that actually exist

quick tundra
#

My two colliders(hook and fish) arent colliding

fish as circle collider and rigidbody, both 2D

image.png image.png
#

and the Fish has just a capsule collider 2d

slender nymph
#

well the first collider is a trigger which is not a solid collider for collisions, it is a trigger volume

quick tundra
#

okay how do i fix this, because toggling Is Trigger false does not fix this issue, none of the functions(either OnTriggerEnter or OnCollisionEnter) fire

slender nymph
#

see, if it was about physics messages you should have said that. your message implied you wanted physical contact (a collision) to happen

quick tundra
#

aah that worked, I was using OnTriggerEnter, and not OnTriggerEnter2D

~~ hey, i'm a complete beginner and i want to add a script to an scene object but i get an error which says "Can't add script behaviour 'inputManager'. The script needs to derive from MonoBehaviour!"
Everywhere i have asked or looks just says that the class name doesn't match the file name, use GameObject.name to find it without actually telling me wtf a class anme is and where i am supposed to run GameObject.name

please help, idk if this is the right place but i couldn't find a "Help" channel sooo.~~

#

how would I reset the position of a collection of rigidbodies? Trying to restart a player position and the player is a ragdoll

edgy sinew
#

Not sure if it’s best solution but I never had any glitches

brazen pumice
#

is there an easy way to iterate through all of them and change Kinematic/reset position/change Kinematic back

edgy sinew
#

Yes by doing exactly what you just said stonks

brazen pumice
#

that makes sense lmao

naive pawn
#

is there an issue with just setting the position of the rigidbody directly? it's documented as effectively teleporting the rigidbody

#

I have two monobehavior classes that I need to run identical code (inserting prefabs into a container). I'm trying to figure out the best way to handle this. I was leaning towards an abstract but don't love the fact that I will have to pass in the prefab and container as parameters since a parent can't access child properties. Other options I found; static class, base class, service locator seem to all have the limitation as well so I assume abstract it is. Figured I would ask for thoughts.

naive pawn
#

what's common and what's different in this "identical code"

low copper
#

When I said child I meant child class (in this case : scene class -> abstract class). Abstract class can't get the scene properties (content + prefab properties) directly. What is duplicate is one method that renders a bunch of prefabs into container.

naive pawn
#

also, the abstract class can absolutely get stuff from the scene

#

an instance of a child class is also an instance of its parents

low copper
#

Content is a empty GameObject. I'm rendering inventory items (prefab) on to a UI panel. So I have the sceneController script, that will have the content + prefab attached to it. But I don't know how to give access to that in the abstract class, so I assume I have to pass it in as parameters.

naive pawn
#

you can have serialized fields in the abstract class, no?

#

inventory items (prefab) on to a UI panel
so prefab instances, gameobjects in the scene, not prefabs

low copper
#

Ahhh....of course...that makes a lot of sense. I didn't even think of that for some reason.

naive pawn
#

technically this doesn't need to be abstract either, with the constraints you've given. just some parent class representing the behavior of instantiating a list of objects into some other object

#

of course if there are other details that would make this invalid on its own, then you would have it abstract

#

another option would be to just have some static utility method somewhere (if it's just a chunk of logic that isn't exactly its own behavior)

low copper
#

Ah ok...so that might be better if I want to repeat this behaviour with something not inventory related.

#

Thanks for the thoughts...I really appreciate it

~~I need a little with understand of my problem with Vectors.

So...

I have a enemy and I wanna set a ray(s) at the direction(y) to player BUT at the same time also use vector needs to set ray to require angle(Making a ray of attack). I'll not show this vector(main_dir) 'cause it almost the same as transform.forward.

At the end I want to get vector that is looking at y-pos of player and also rotates along x depending on transform.forward (that is, depending on the enemy's rotation)

My actually problem/issue that when I'm trying to go at the side from enemy's rays these rays are starting to move up and down. I don't understand how its actually possible. I tried to search information and there was also nothing about my sort of problem.

Maybe you can help where do I have an issue in the code?

I am open for all questions.


//dirToTarget is vector to player(not normalized!)
Vector3 planeNormal = transform.right; 

Vector3 fwd = Vector3.ProjectOnPlane(transform.forward, planeNormal).normalized;
Vector3 dir = Vector3.ProjectOnPlane(dirToTarget, planeNormal).normalized;

Vector3 main_dir = Quaternion.AngleAxis(currentAngle, transform.up) * transform.forward;
//currentangle to set angle 

float xAngle = Vector3.SignedAngle(fwd, dir, planeNormal); 

Vector3 direction = Quaternion.AngleAxis(xAngle, transform.right) * main_dir;

//Vector3 direction is going to use for a ray calculating.

It's sounding like you probably just want some kind of vector projection but it's unclear

Okey, one moment.

i think i understand

#

you rotate your local baised on current angle with transform up and forward yea?

midnight tree

#

oooo

so when you rotate a vector by tilting that changes your "up"

that yaw happens when your look dir is no longer horizontal

HI everyone, I opened Unity earlier this week and am trying to make a basic tower defense game. I found a tutorial on YouTube, but I don't understand why my display is different from theirs. Could someone help me? (1st image is the tutorial, 2nd image is my screen)

This is because you have scene-view gizmos disabled

wintry quarry
#

you don't

#

Also, your top bar is laid out a bit differently. This could just be due to different defaults in different editor versions

You can rearrange the groups of buttons

Hey, it's me again. Still struggling with my tutorial 🥲 I'm trying to drag a sprite into my scene, but the sprite goes under the tilemaps and I get this message in my logs: "Sprite Tiling might not appear correctly because the Sprite used is not generated with Full Rect. To fix this, change the Mesh Type in the Sprite's import setting to Full Rect." Except when I look at the Unity documentation, I can't find the steps to do this, and the screenshots are different because it's not the same version of Unity. Do you know where I can change this setting to see if it solves my problem ?

Capture_decran_2026-01-29_190454.png
wintry quarry
#

You can change the sprite settings there

#

As for the rendering order you need to look at the Sorting Layer and Order in Layer of the tilemap vs the Sprite Renderer

radiant jacinth
wintry quarry
radiant jacinth
#

So, put the ground in the “Default” Sorting Layer and create a specific one for buildings?

edgy sinew
naive pawn
#

the position of the rigidbody, not the position of the transform

#

modifying the transform would indeed lead to a desync

midnight tree
# naive pawn what exactly is happening here that you want to happen differently?

Blue - player
White shape - enemy
Black - rays attack
Red - direction to the player
Yellow - rotation of the enemy

At the end I DONT want to have an example on 1st image. **I want the scenario at the image number 2. **

The direction of rays changes when player is moving aside the enemy and that is quiet annoying. I want just the rotating on the y-axis without any changes on the another axes.(I mean rays of attack are always looking with transform.forward and I change the y-axis of the rays due the script.)

Screenshot_2026-01-29_at_19.43.37.png Screenshot_2026-01-29_at_19.45.30.png
naive pawn
#

ah, i see, i confused y-axis rotation with pitch

#

this makes much more sense

#

if the player is in front of the enemy, but slightly above or below, would the enemy look up or down accordingly?

#

well, the attack specifically

#

if not, it would just be a projection like praetor mentioned

#

if so, it would use projections, but you'd also have to check how far away the player is from the facing direction, and see if that's in a threshold

edgy sinew
naive pawn
#

If you want to continuously move a rigidbody use Rigidbody.MovePosition instead, which takes interpolation into account.

edgy sinew
#

Sure whatever, if you’re sure then ok cool

naive pawn
#

i mean, i don't doubt that there's an issue, ive heard this recommendation of kinematic -> teleport -> dynamic before

#

but if what you're saying is the issue directly contradicts docs, i'm not gonna immediately believe it lol

#

docs can be wrong, sure, but i'd like to see some evidence or a clear description of the issue

Can you disable root motion on single animations or block it through code?

Right now I only want it on the dodge roll and do it like this:

public void OnAnimatorMove()
{
    if (!IsDodging) return;
    var deltaPosition = _animator.deltaPosition;
    if (deltaPosition == Vector3.zero) return;

    _characterController.SimpleMove(deltaPosition / Time.deltaTime);
}

But I assume with more complex animations that is going to be a can of worms 😄

Yo. Got a potentially major bug with unity

#

button callbacks don't work if you lower the resolution

polar acorn
#

As in UI? You're probably covering it up with another object so you can't click on it

swift crag
#

Yes, that's very likely

#

If you are using the old input system, you can select the Event System and look in its preview pane (bottom of the inspector) to see what's being pointed at

#

for some reason, the new input system doesn't show this

lofty sequoia
#

could be--all that I have in my scene are some buttons. When I set the game view to free aspect, all buttons work at normal res (1920x1080 ish) but when scaling down to like 800x300, some buttons become unresponsive

yea its configured and I have the extension

wintry quarry
#

If so, I'm like 80% sure you don't have it configured. It should be saying "Unity Message" or "Unity Event" over Update()

spare tundra
#

lemme relook at that page I had followed the steps and went thru packaghe manager and got the extension I dunno

#

im not seeing the extension under package manager to update. the extension is installed

#

and what about the other steps?

spare tundra
#

only other step is to set editor as default and it is

slender nymph
#

well no, that's not the only other step. but show where you did that

spare tundra
swift crag
#

this is not set up correctly

spare tundra
#

and yes it is bro

swift crag
#

"Visual Studio Code (internal)" is wrong

spare tundra
#

says do package which I cant find and then default editor

slender nymph
#

if you think that is the only two steps then you are missing the vs code extension

swift crag
#

Note that if you just installed the package, it can't actually compile and start working if there are outstanding compile errors

spare tundra

you should be seeing something closer to this, with a version number at the end

you only need the "Visual studio editor" package in your unity project

        agent.isStopped = true;
        animator.applyRootMotion = true;

        animator.SetBool(enemySO.meleeEnemyAttacks[0].attackName, true);

        yield return new WaitForSeconds(enemySO.meleeEnemyAttacks[0].attackTimer);

        animator.SetBool(enemySO.meleeEnemyAttacks[0].attackName, false);
        animator.SetBool(enemySO.meleeEnemyAttacks[1].attackName, true);

        yield return new WaitForSeconds(enemySO.meleeEnemyAttacks[1].attackTimer);

        animator.applyRootMotion = false;
        agent.isStopped = false;
        agent.ResetPath();
        agent.Warp(transform.position);

        yield return new WaitForSeconds(0.1f);

        SwitchState(EnemyStates.Moving);
    }

does anyone know how to fix root motion issues? when the animation stops the enemy snaps back to the navmesh agent position, basically "rolling back"

using UnityEngine;
using UnityEngine.AI;

public class ApplyRootMotion : MonoBehaviour
{
    [SerializeField] Animator animator;
    [SerializeField] NavMeshAgent agent;

    void Start()
    {
        animator = GetComponent<Animator>();
    }

    void OnAnimatorMove()
    {
        if (!animator.applyRootMotion) return;

        agent.transform.position += animator.deltaPosition;
        agent.transform.rotation *= animator.deltaRotation;

        agent.nextPosition = agent.transform.position;
    }
}

ApplyMotion is in the same object as the Animator

spare tundra
#

yea I cant seem to get that installed into unity

#

its not finding it

also installing by name does not mean using its display name

i have an animated button pixelart which i want to add to a button (object) what is the difference between animator, animation and using the button transition "animated"

spare tundra
#

Why the difference when creating a monobehaviour script

image.png image.png
#

the one is in tutorial video on left

timber tide
#

Left side has some extra c# libraries, but monobehaviours (at minimum) only need UnityEngine

spare tundra
#

yea I guess ill just mirror the tutorial and type those in

timber tide
#

If you're using lists in your scripts then you'll also be using the Generic's library

spare tundra
swift crag
#

They no longer include using System.Collections; and using System.Collections.Generic;

spare tundra
#

so I dont need to add them to the script even though the tutorial has them?

polar acorn
#

Do you need those namespaces?

swift crag
#

If the tutorial later uses a type from one of those namespaces, you'll want to add the directives

#

e.g. the latter is where you get List<T>

#

the former gives you IEnumerator

#

both of these come up somewhat commonly

#

A using directive doesn't actually "import" anything; it just lets you write a shorter name

#

using Foo.Bar.Baz means I can write:

public Thing myVariable;

rather than

public Foo.Bar.Baz.Thing myVariable;
#

using UnityEngine; means that you can write MonoBehaviour instead of UnityEngine.MonoBehaviour

#

hence why that's still there

spare tundra
#

so if I'm following what your saying using.whatevernamespace just basically allows shorthand in code?

swift crag
#

Correct. It's not actually necessary

spare tundra
#

ok

swift crag
# 
public List<int> numbers;
public System.Collections.Generic.List<int> moreNumbers;
#

The first line is only valid if you have a using System.Collections.Generic; directive up top

#

Your IDE should insert this for you if you try to use List

spare tundra
#

ok ok im following

#

using UnityEngine.InputSystem;
Vector2 moveInput = Vector2.zero;
so is this using that namespace? im trying to figure out how to tell or if its just something you learn eventually

polar acorn
#

You could also just look up the class in the documentation and see what namespace it is in

spare tundra
#

oh yea it underlines everything red that requires that namespace

#

the script does change in tutorial smh

#

lol the tutorial has you use chatgpt

swift crag
#

The full name of the type is UnityEngine.Vector2

#

similarly, System.Collections.Generic.List<T> is a type

#

a type is a kind of thing

Can someone help me learn how variable references work in C#? Here is some sample code :

public class SaveData { public Dictionary<string, int> inventory = new Dictionary<string, int> {}; }

public class SaveManager { public Dictionary<string, int> InventoryIndex(){return saveData.inventory;}}

public class Example { 
    public void Example()
    {
         Dictionary<string, int> inventory = SaveManager.InventoryIndex();
         foreach (var item in inventory)
         {
              item.Value++;
         }
    }
}

Does SaveManager pass a reference to saveData.inventory by default. I just want to make sure I'm not editing the actual inventory in Example.Example(); Is there a rule of thumb on how it works? Google says "In C#, arguments are passed by value by default, whether they are value types (like int, structs) or reference types (like class instances, string, arrays). The mechanism creates a copy of the value being passed into the method's local parameter. However, the "value" of a reference type variable is the memory address (reference) of the actual object on the heap. When this reference is passed by value, the called method receives a copy of the reference, but both the original and the copy point to the same object in memory.". Which doesn't make sense to me. I also know my ServiceLocator passes class objects by reference (one instance) so maybe classes have different rule? Sorry for the vague question...just trying to learn how stuff works and not sure how to ask properly.

naive pawn
#

for variables of reference types, the value stored in the variable is a reference to the actual object somewhere else in memory

#

classes are reference types, so they go by these rules, whereas structs are value types

naive pawn

#

I'm building a craft system...so I want the inventory on the bottom of the page to change but not what is actually in their inventory

#

So it seems like my current code will not edit the actual inventory. But you said I need to copy it?

naive pawn
#

my current code will not edit the actual inventory
it will

#

sounds like you may need a separate inventory store and an inventory view? but i'm not sure what exactly you're going for

Though, perhaps they're boxed due to the for each. Not sure why there would be a .Value field...

low copper
#

I found this approach : var copied = new Dictionary<KeyType, ValueType>(originalDictionary);

#

Man...I never heard of boxing before

ivory bobcat
#

If they're simply wanting to iterate the collection and increment the value, they could probably box the integer in a class and increment the value by accessing the object.

tawny haven
low copper
#

I was just trying to give a simple example. What I want is to remove any inventory items used in the crafting system from the actual inventory count. Think minecraft/grid.

ivory bobcat
#

I'm going to assume they'll be eventually adding other features to these values as well, like locked or non stackable etc

naive pawn

in minecraft the cursor is another inventory slot

I made a repo on my account through the web, cloned it to a local folder which gave it a name with dashes

My project has spaces in the name, not dashes. How is this supposed to work? Do I just put the whole project inside the repo folder so it'd be like "..\My-Project-Name\My Project Name"?

Hello. I am trying to make a simple physics based 3D game. I am using rigidbody and new input system to move the player. I trying to recreate player movement like in animal crossing but I also trying to keep physics interactions like horizontal winds or push pads, friction (I am using physics material for this) etc.

I tried setting the rigidbody.linearVelocity = player input * player speed which gave me the snappy directional movement but this also killed any external forces when there is no input.
I tried using rigibody acceleration but that gave me like true physics movement with curvy movement instead of snappy movement.

Is there a way to have animal crossing like movement and also have external physics interactions?

keen dew
#

If you want to set the linearVelocity directly then you have to apply all external forces manually

#

What other way is there?

#

How would any other system know how you wanted your character to "feel"? Your request is already an contradiction. You cannot have 1:1 snappy movement and have external forces influence that, since your snappy movement by definition is snappy.

#

You're going to have to handle this with some logic that only you can define. If the player is in a wind zone, maybe they store a state (IsInWind), and only then the movement isn't "snappy", so that character can freely add the velocity of the wind to their current movement.

#

The proper way to do a character though is to actual apply forces via input as well so that you can add up the total velocity of the player for that frame. The input can just have a high acceleration. When they're in a wind zone/or boost pad, it simply is just a high external force that pushing against it "takes time" to go against it.

And then coming out of the zone/pad would have the player slowly decelerate by nature because their current speed would have to come down to their max speed (or zero if there's no input).

cunning narwhal
naive pawn
#

that doesn't particularly make sense

#

a git repo is typically the project

cunning narwhal
#

Oh ok let me experiment and try that

naive pawn
#

if you want to go for something atypical like that, you'll have to manage the repo setup yourself, which isn't impossible, but i wouldn't recommend it when you're starting out

#

also, if you already have a project, create the repo as the project and upload that, that'll be easier

#

what git client are you using?

cunning narwhal
#

And yeah I already have the project made so git came after the fact

naive pawn
#

mm, not familiar with fork so i can't walk you through that, sorry

frosty hound
#

Technically, you can just copy paste everything in if you just want to see how it works from "scratch".

#
  1. Create the repo on github (or wherever)
  2. Clone the repo via Fork so that it creates the folder on your PC
  3. Put in the gitignore (found online) for Unity into the folder and commit that. This is important
  4. Copy the entire contents of your Unity project into the repo folder on your PC
  5. Commit the entire thing to the repo

Then you can just delete your local (original) project and then in Unity Hub, just point the project to the repo folder to link it back up.

Hi everyone, I'm still having trouble following my tutorial, this time with a script. In the tutorial, he writes the script that I copied (see attachment) and he also changes the “Active Input Handling” parameter to ‘both’ in the “Player” category of the Project Settings, except that when I run the game on Unity and try to do what the script is supposed to do, I get an error message and I feel like it's this setting that's causing everything to crash, but I don't know how to fix the problem. Can you help me ?

Do you have a camera in your scene with the MainCamera tag set?

polar acorn
#

What makes you think it has anything to do with the input handling?

frail hawk
#

half of the code only as image

#

You have a null reference error. Something on that line is null.

do we just guess this is the Towerplacer.cs

the tag is important here not the name

frosty hound
#

Your game is looking for Camera.main, which is the camera with the MainCamera tag.

by default this is the case but you might have added your own cam and deleted the old one, as Osteel pointed out

It was set to “Untagged” by default. I didn't know it could be linked like that. It works now, so thank you. 😅

Hello Friends, I'm not sure if this is the right place, but I'm trying to connect my unity hub project to Visual Studios to make a mod for the game ROUNDS.

I've installed Visual Studios 2022 and checked the box next to Game Development with Unity, but VS doesn't appear in my list of options for external script editors in Unity Hub. (Visual Studios Code is there, but that is a different interface that won't work for what I need)

it is unity 2018.4.34f1, necesarry for the mod

imo thats already more agreeable but its a slippery slope

#

ai is wrong, and frequently

#

even if you use to learn new things it can teach you the wrong things

#

you said it yourself, 4 months in and you cant really write your own code without errors if you arent using ai to help you out, it might be a sign of something

#

try going on a bit of an ai detox, if you have to learn something, google it, look on forums, ask here, try things. It will make you a better programmer overall

because its all about problem solving, and if someone else always tells you exactly how to solve those problems you suffer the risk of skill atrophy.

hlsl can be daunting, but at its core its a very simple c-style language. The confusing parts are the inputs and outputs.

on a separate note, i got the gerstner wave shadergraph working without HLSL but im having trouble syncing it with the physics so my player can actually walk on the waves (i know its on the GPU and doesnt have collisions btw, im trying to add a separate physics object and just sync the shader with the object)

stone heron
#

@opal zodiac one of the skills of coding or game dev in general is referencing documentation. Nobody remembers everything. Coding is about breaking down problems into solvable chunks and then accessing the resources to remind yourself how to do it

#

most stuff in unity i just remember by now after like 8 years but if i forget something I just look it up, find an example etc

Typically, when you finish a script, you'd understand what that script does. If not, then you go line-by-line until you understand what each term, phrase, method, etc., does . . .

I think my issue is that im moving too fast and i need to practice the fundamentals till theyre second nature. I understand Composition, Inheritance, classes and im able to read/iterate code made by AI however i struggle to create code from scratch without a prompt due to lapses in my knowledge

There is a way to use "DefaultAsset" variable out Unity Editor?

I'm trying to compile my project, but get an error when I set it out "if UNITY EDITOR"

#

I want to refer my folder inside the variable

image.png
solar hill
#

is your ide properly set up?

polar acorn
onyx blaze
swift crag
#

DefaultAsset is editor-only, unfortunately

#

What do you need to load here?

polar acorn
#

Instead of loading a folder, you should make a ScriptableObject that has references to the other components, then you can do a LoadAll for that asset. Instead of having a Database folder, you'd just have assets that are only containing this specific set of data

swift crag
#

bingo

#

(or just load it by name directly)

polar acorn
#

So, instead of loading the Shinobu prefab, you'd load an SO that has a reference to that prefab

#

Once it's in Resources it all basically blobs into one big pile with no directory structure

onyx blaze
#

This folder will have various characters

So will have various files inside
I was trying to avoid to add one by one

swift crag
#

(you'd need to know the actual asset path for the DefaultAsset, anyway -- the name alone would not be helpful)

onyx blaze
#

Let me share my code

swift crag
#

Literal names get problematic when they're prone to change

#

like if you do Resources.Load("JeffKillblaster")

polar acorn
swift crag
#

and then you rename him to BillMcMurderson

#

now it's broken

#

but Database sounds...pretty set in stone

#

I wouldn't be concerned if I saw Resources.LoadAll<Character>("Database/Characters")

#

(i'd add an extra folder, because I bet you'll want other databases later)

onyx blaze
swift crag
onyx blaze
swift crag
#

Resources.Load does not care about actual file paths

#

File paths do not exist in the built game

#

The names you use are derived from the folder and asset names you used

#

I guess I'm not sure what you're worried about right now

onyx blaze
#

I was worried if typing the exactly name folder will works when compile the game
But, if will works, okay ^^

Try closing unity then deleting your library and packages folder and reopening unity

it results in nonsense errors like this

Do the following:

  • Close the editor
  • Delete the UPM package cache. This page tells you where to find it.
    • This will make Unity download the packages again if they need to be reinstalled
  • Delete the Library folder in your project
    • This will force Unity to reinstall the packages
  • Reopen the project

If you don't clear the global cache, you'll keep getting the same broken package over and over

the rest is messy

Also a general tip, setting targetFrameRate to a low value makes it easier to debug sync/jitter issues.

And is the camera a child of the rigidbody object or what?

Usually camera movement is done in lateupdate anyway

Otherwise another script might move stuff in Update after the camera has moved for that frame

unrelated, but also why is that clamp happening after passing it to the camera ? 🤔

#

it's following the position of an object that happens to be on the rotating part of the ball

#

Step 1 here is switch your tool handle position to Pivot

#

so you can actually see where the objects are

#

Step 2 is move the position of the TrailTarget object to the center of the ball:

#

or do you want the trail on the ground, rather than the center?

vapid egret
#

Hey everyone! Y'all ready for some dummy questions?

#

What would you define as a vertical slice?

red igloo
wintry quarry
# red igloo I want the trail on the ground

ok all you need to do is this then:

  1. Move the TrailTarget's local position to 0,0,0 (the center of the ball)
  2. Change your code to this:
    ⁨cs transform.position = trailTarget.position + Vector3.down * 0.5f;⁩
#

delete the line about ⁨transform.rotation⁩, it's not needed and does nothing

#

Once it's working you can change that 0.5f to be something configured in the inspector somewhere - it's whatever the radius of your ball is

#

you can adjust it as needed to match the size of the ball

#

my suggestion was to use an SO instead of a direct sprite field

#

simply if other run time scripts need to work with other sprites they can all get a reference to their respective one from the same field

#

if that makes sense

#

i guess i was overthinking it slightly but the idea is the same in principle.

wintry quarry
#

basically at some point something needs to reference the sprite somewhere and pass it where it needs to go

solar hill
#

yeah

wintry quarry
#

it's all just a game of references and interscript communication

blissful vessel
#

What would it look like doing it through an SO? I'd like to keep my script that adds the component clean if I can

wintry quarry
#

just an extra layer of abstraction

solar hill
#

the SO would let you keep a list of multiple sprites

#

well

wintry quarry
#

you can keep a list in either case

solar hill
#

the field can do that too on the script itself

#

yeah

#

but i would say its maybe good habit though

blissful vessel
#

ty both 🙏

solar hill
#

its not nescessary i would just use SOs for stuff like that, easier to edit later rather than slouching through scripts, especially if you need to get references to the same sprites elsewhere

boreal ingot
#

if i am in a lobby and force quit the game and then reopen it and try to create a lobby because i never left the other one i get rate limited. is there a way to destroy the other one in this example? maybe when reopen search if my id has an open session?

anyone knows the correct way to handle this guys?

im making a train game similar to the board game rush hour. and im moving the individual peices along a spline like this. but to move it im transforming the position, which means when my object is supposed to collide with a wall or another train, it just goes straight through the other object. is there another method i can do to move an object along a spline (or path) using the rigidbody instead of transforming the position

image.png
#

sorry this might not be the right channel to put this in my bad!

grand snow
#

You would need to instead move the object via physics

#

Meaning you have to grab the next goal pos from the spline and use physics to move towards that

#

translation bypasses physics so will not work (meaning you cant use spline animate anymore)

#

@barren iris

barren iris
#

yeah thats chill

barren iris
grand snow
#

spline container/spline has functions to sample a position so thats easy

barren iris
grand snow
#

there are also functions to get the relative position 0-1 on a spine for a 3d position

barren iris
#

float splineLength = splineContainer.CalculateLength();
progress += input * (moveSpeed / splineLength) * Time.deltaTime;

grand snow
# barren iris i got this i think

Yea if you have your own "spline progress" float you can increase it, sample new spline position and change the rigidbodys velocity (or use MovePosition) to move via physics.
If you detect the rigidbody stops moving then it "hit" something (or use physics events)

can someone take the time to help me with my wall jumping mechanic? My wall check object doesn't flip to where my character is facing and i have no idea on how to fix it

#

specifically how to make it so when my character turns around, the game object flips with it

slender nymph
#

well how are you turning the character around

viscid heron
#

moveInput.x = Input.GetAxisRaw("Horizontal");

slender nymph
#

i didn't ask how you are getting input, i asked how you are turning the character

viscid heron
#

oh uh

#

lemme check

#

gimme a min i didnt write most of this code lol

slender nymph
#

if it is AI generated then i will not be helping you

viscid heron
#

my partner on the project wrote it 😐

slender nymph
#

then why not just ask them

viscid heron
#

dont have there phone number

#

this is a school project

grand snow
#

discord? how do you even have the project

viscid heron
#

its through unity version control, i just signed in through the school email cuz i wanted to keep working on it

#

void Move()
{
moveInput.x = Input.GetAxisRaw("Horizontal");
moveInput.y = Input.GetAxisRaw("Vertical");
moveInput.Normalize();

 if (moveInput.x != 0)
 {
     animator.SetBool("isWalking", true);
 }
 else if (moveInput.x == 0)
 {
     animator.SetBool("isWalking", false);
 }

 // Sprite Flipping depending on movement direction
 if (moveInput.x < 0) // Moving left
 {
     spriteRenderer.flipX = true;
 }
 else if (moveInput.x > 0) // Moving right
 {
     spriteRenderer.flipX = false;
 }

}

solar hill
#

you have a school project with a partner and you dont have a way to contact them?

#

also

radiant voidBOT
viscid heron
#

i dont see why this is relevant

grand snow
#

asking who wrote the code how it works is often the fastest way

viscid heron
#

i am aware

slender nymph
#

also you're going to have a harder time getting help if you don't even understand what is already there and working

grand snow
#

If looking right is the default and flipx is false, they are looking right!

viscid heron
#

oh i thought that was just for the sprites?

#

not the physical object

grand snow
#

It is but if you did the scale -1 trick then flipping the sprite would be wrong

#

Anyway the code flips the sprite based on user input so thats why that works

#

So reading flipx will work to know the "last input direction"

#

or you record your own bool based on input

viscid heron
#

so would i want to flip the wallcheck using flipx in the else if?

slender nymph
#

or just determine which direction to do the wall check in based on the flipX property

grand snow
#

change the direction in which you check for walls? yes

#

you can do something like this:
⁨⁨```cs
Vector2 checkDir = new(spriteRenderer.flipX ? -1f : 1f, 0f);

#

⁨spriteRenderer.flipX ? -1f : 1f⁩ is a fancy way to do:
⁨```cs
Vector2 checkDir;
if(spriteRenderer.flipX)
{
checkDir = new(-1f, 0f);
}
else
{
checkDir = new(1f, 0f);
}

viscid heron
#

i dont think this helps what im trying to do

slender nymph
#

why not

viscid heron
#

i dont think im explaining this correctly

slender nymph
#

show how you are doing this wall check

viscid heron
#

the sprites work fine

slender nymph
#

the advice given is not about fixing the sprite, it is about using that property to determine what direction your wall check goes (because presumably it is a physics query like a raycast)

grand snow
#

its the direction to raycast to check for a wall

#

looking right? shoot to the right.
looking left? shoot to the left.

viscid heron
#

Wall check is an object on the player that detects if it is hitting a wall (which works.)

The problem is that the object doesnt flip to where the character is facing.

I can also send my walljumping block of code if that helps

image.png image.png image.png
slender nymph
#

how does it "detect if it is hitting a wall"

#

i certainly hope it isn't just a physics message (OnTrigger/CollisionEnter)

grand snow
#

yea probably is

viscid heron
#

when the object comes into contact with a object with the wall tag and wall layer

grand snow
#

which makes this harder for no good reason 😆

slender nymph
viscid heron
#

would it just be easier if i sent the script, me and this other coder literally dont know what we are doing and we are just following youtube videos

slender nymph
#

typically when someone asks how you are doing something, yes they mean in the code.

#

at least that's the case in a code channel. like here.

viscid heron
#

myb bro i thought you just wanted me to explain it, im new here

slender nymph
#

!code 👇 and don't ignore it this time

radiant voidBOT
viscid heron
solar hill
#

the bot message?

#

its showing how to send code properly, either through pasting services (prefered) or using inline for smaller chunks

viscid heron
#

cant i just send the file like i just did?

slender nymph
#

what do the bot instructions say

viscid heron
#

or did it get hidden 0r something

cosmic dagger
viscid heron
cosmic dagger
#

that's why the bot exists; to explain how to properly send code . . .

solar hill
viscid heron
#

how do i post it with a scroll bar thingy on the side of it

#

or can i not do that

slender nymph
viscid heron
#

ok ok

slender nymph
#

Basic reading comprehension is a prerequisite for using unity

viscid heron
#

its big but thats the wall jump code

slender nymph
#

"its big"
So what did the bot message say about large blocks of code

viscid heron
#

i literally did what it told me to d

#

put three backquotes on the front and the end\

solar hill
viscid heron
#

i was told by boxfriend here that it would add a scrollbar

slender nymph
#

I said no such thing.

solar hill
#

the pasting services are free and half of them dont require accounts, if you want us to help you, make it easy for us.

slender nymph
#

Again, reading comprehension

solar hill
#

nobody wants to scroll up and down a discord channel just to see all your code at once

viscid heron
#

im sorry that im not making it easy for you guys, i dont know what im doing

solar hill
#

read the bot message

#

please

#

there are links

#

go to the paste service, paste your code, send us the link

viscid heron
#

hope that helps

#

i can do the whole script if you like too

solar hill
#

would be prefered as well but this works too if the issue lies here

viscid heron
#

also thank you for letting me know that one of the links didnt require an account, that was one of the reasons i wanted to try discord first lol

#

i know there was some way to add some sort of scrollbar to the code on discord but i guess not

solar hill
viscid heron
#

yes

viscid heron
#

anything to fix it yet or still looking?

i'm reading up on Physics.RaycastNonAlloc and i'm a little confused as to what the size of the array does. i've tested a little and haven't found out any real differences based on values. what does this do exactly so i don't mess something up?

image.png
grand snow
#

That's why it returns the amount

#

Therefore make the array with a good size that you deem is big enough

dim yew
#

so the size of the array translates to the amount of hits the buffer can store?

grand snow
#

Yes the max amount

dim yew
#

cool thanks ^_^

grand snow
#

If it hit/overlapped 15 things but the array is 5 in size then you get just 5

unity really needs general help but did somebodys unity start behaving weird after 6.3 updates
rotating object in editor with gizmos rotates is really fast, small movement results in 700 degree rotation and such
only on rotating objects and on every platform (windows, mac, linux) 6.3.3 version

frosty hound
#

There's another issue too where if you're reversing the rotation gizmo it goes the wrong way for a bit.

prime goblet
#

im using 6.3.2 and im not experienceing these issues, but then also the latest version is 6.3.6 so maybe try that?

Hi 👋 I've got a little issue... I'm making a script that should be able to use a void of another GameObject but after following and debugging a tutorial and I have an error constantly.

private bool isActive = true;
public GameObject player;
private void OnTriggerEnter2D(Collider2D other)
{
    Debug.Log("Trigger touched by :" + other.name);
    player = __gameObject.GetComponent<player_character_movement>().JumpRefill();__
    if (player != null && isActive)
    {
        
    }
}

(I'm trying to translate my error from french)
Impossible to convert type 'void' into 'UnityEngine.GameObject'
Thanks !

Also they're not "voids" they're methods / functions. Void is no return type

wanton geode
wintry quarry
#

you're trying to do some weird frankenstein combination of these two. You sorta have the concepts floating around but all the specifics of how you wrote it are incorrect/out of place

#

Also naming a class ⁨player_character_movement⁩ is very confusing for everyone.

wanton geode
#

Yeah, I tried following a tutorial but it got me an error so I tried a bunch of things and did not really find anything

wintry quarry
#

follow the tutorial

#

instead of guessing at stuff

#

If you got an error following the tutorial you did something wrong.

wanton geode
#

in the tutorial the guy does
var player = gameObect...
But for me it doesn't work

rich adder
#

Your "player" should be storing a "player_character_movement" then call the method

wintry quarry
#

finish the complete line that is in the tutorial

#

and show what you tried

#

and show what error you got

#

When you fully check over everything, you will see that you did something differently

wanton geode
#

I mean, yeah the code works in theory but it does not work 'cause i need to use a OnTriggerEnter2D instead of OnCollision2D, what I wan't to do is this the same but it just doesn't work with collision because(I think) OnCollisionEnter2D works only if the GameObject isn't set to trigger.

wintry quarry
#

If you want a trigger interaction, you would use a trigger collider and OnTriggerEnter2D

#

If you want a real collision, you use a non trigger collider and OnCollisionEnter2D

#

Neither of those changes all that much about the little code snippet you're having trouble with

wanton geode
#

I've made it so my character has doublejumps that can refill over time, but when I touch a certains object, it instantly recovers 1 double jump.
Here is the code that could work if I used OnCollision2D :
using UnityEngine;

public class JumpRefillScript : MonoBehaviour
{
private bool isActive;
private float resetTimer = 5;
private void OnCollisionEnter2D(Collision2D other)
{
Debug.Log("Refill touched");
var player = other.collider.GetComponent<player_character_movement>();
if (player != null && isActive)
{
player.JumpRefill();
isActive = false;
Debug.Log("Refill done");
}
}
void Update()
{
if (!isActive)
{
resetTimer -= Time.deltaTime;
if (resetTimer < 0)
{
isActive = true;
Debug.Log("");
}
}
}
}

but line 10 has an error if in the void i put OnTriggerEnter2D

wintry quarry
radiant voidBOT
wintry quarry
#

and don't just say "has an error"

#

show us:

  • The exact code you tried
  • The exact error you saw
#

We can't do anything without actually seeing the problem. A vague description isn't enough.

wanton geode
#

Ok, so I've played arround a bit more with my code and managed to get a code without any errors in it...
using UnityEngine;

public class JumpRefillScript : MonoBehaviour
{
private bool isActive = true;
private float resetTimer = 5;
private void OnTriggerEnter2D(Collider2D other)
{
Debug.Log("Refill touched");
var player = GetComponent<player_character_movement>();
if (isActive == true)
{
player.JumpRefill();
isActive = false;
Debug.Log("Refill done");
}
}
void Update()
{
if (!isActive)
{
resetTimer -= Time.deltaTime;
if (resetTimer < 0)
{
isActive = true;
Debug.Log("Refill recharged");
}
}
}
}

The issue is, when player and entering in the trigger i get this error :

image.png
wintry quarry
#

why did you just throw your hands in the air here and do this completely differently than before

#

You need ⁨⁨other.GetComponent<player_character_movement>()⁩⁩

#

the way you have it right now it's trying to get that component from your own GameObject, i.e. the one this script is attached to

#

you want to get it from the thing you triggered with

wanton geode
#

aaaah alr

wintry quarry
#

you're also probably going to want to check that it's actually the player you collided with.

#

But that can come next

wanton geode
#

oh yeah I saw that. Anyway, it works now so thanks and really sorry if I'm doing things a bit randomly I'm still trying to get around and trying to undertstand what I'm doing and what to do

vital barn
#

How

naive pawn
#

in unity asset terms, Texture2D is an imported asset, and Sprites are assets generated from that Texture2D

frail hawk
#

a sprite is a texture would fit yes but the oppsosite we can argue

vital barn
naive pawn
#

yes, you can create sprites from textures

#

i just said that

#

that doesn't mean they're the same thing

vital barn
#

In the context of files, it's the same thing

naive pawn
#

a single texture2d can have multiple sprites from different rects

vital barn
naive pawn
#

so that would be a texture that has multiple sprites, yes

vital barn
#

Well, the point is that a sprite is not just something separate, sprite it's an area on the texture

stuck parrot

how do I learn coding for unity? I mean I kinda can read the code and after uning my brain for 5 or 10 minutes it does start making kinda sence but how on earth would I as a beginner write a code like that
⁨⁨```cs
using UnityEngine;

public class PlayerMove : MonoBehaviour
{
public float moveSpeed = 6f;
public float jumpHeight = 1.5f;
public float gravity = -20f;

private CharacterController controller;
private Vector3 velocity;

void Start()
{
    controller = GetComponent<CharacterController>();
}

void Update()
{
    Vector2 input = new Vector2(
        Input.GetAxis("Horizontal"),
        Input.GetAxis("Vertical")
    );

    Vector3 move = new Vector3(input.x, 0f, input.y) * moveSpeed;

    // grounded check
    if (controller.isGrounded)
    {
        if (velocity.y < 0)
            velocity.y = -2f;

        if (Input.GetKeyDown(KeyCode.Space))
        {
            velocity.y = Mathf.Sqrt(jumpHeight * -2f * gravity);
        }
    }

    // gravity
    velocity.y += gravity * Time.deltaTime;

    // combine horizontal + vertical
    Vector3 finalMove = move + velocity;

    controller.Move(finalMove * Time.deltaTime);
}

}

 out of thin air. It seems like guessing magic spells for me.
This one is made by AI because no forum or documentation is actually explaining it
naive pawn
#

you would learn, and as you get more knowledge and experience, you can start synthesizing new code from your knowledge/experience

#

you can think of them as magic spells, sure. but mages don't guess, they know from study and practice

#

that's how you get knowledge and experience

stuck parrot

no?

#

there are beginner resources pinned in this channel, have you tried checking those out

naive pawn
stuck parrot
naive pawn
#

"beginner" is a vague term. if by "beginner" you mean "someone who can't code", you would not write code as a beginner

#

you would first learn how to write code, and then you wouldn't be a beginner anymore

#

it's a long process, this is an entire skill on its own

but if you are new, i´d recommend learning the basic of c# first

#

just console app or some win forms beginner projects

stuck parrot
# frail hawk but if you are new, i´d recommend learning the basic of c# first

the basics are only that you do math with variables which you assigned values to. thats all what I know about C# so the bigger problem is to guess what functions unity is hiding. I had spend so much time just to find out you can use the character controller insdead of assigning movement to every button and joystick seperatley

naive pawn
#

you don't have to guess

#

you can check docs and/or follow guides or tutorials

#

insdead of assigning movement to every button and joystick seperatley
you still have to do this, input handling is separate from actually moving the character (but there are defaults provided)

stuck parrot

you will find out about the most used componenets over the time

depends on the specific thing and your past experience. "best" is impossible to define.
docs are the overall most accurate resource (unless you count source code) but they are, by nature, technical documents
if you aren't willing to go to that yet, look for guides or tutorials, like those in unity learn 👆 or pinned in this channel

# vital barn Google

To be honest, the ability to search for information is no less important than programming itself

frail hawk

i have a feeling that you are not researching enough before starting development.

like as you said you started programming your own player controller than found out about the character controller

# frail hawk i have a feeling that you are not researching enough before starting development...

because with google I always feel like hitting the wall. even for player movement which is like step 1 of bringing a game to life but theres no clear explaiation, or code to copy. Isnt moving a character the same thing in every game and should be a pick of a few different variations (first or third person)? thats the reason I use AI is because google just isnt a good place to look up stuff anymore

so whats the best workflow now. not knowing how do do something > googeling this problem > reading documentations, watching videos and coming up with ideas that eventually work? I understand that programming is not easy, and that unity needs code to work. But shouldnt game development be more of an creative and artistic task?
