[queen adder]

Hey fen u seem to be good with physics could help me with something?

[slender nymph]

() to call a method

[frosty hound]

.GetComponent<NavMeshSurface>();

[slender nymph]

but also, just make your navMeshObj variable a NavMeshSurface. you don't need to reference the GameObject just to call GetComponent on it, just reference the component directly

[queen adder]

On line 12 put a [SerializeField] infront of private

[coarse compass]

I want to do that yes but I cannot drag a component from another object to a public variable field right?

[slender nymph]

yes you can. that's literally what i suggested to do

[queen adder]

Public or private with a [SerializeField] it doesnt matter

[swift crag]

Unity would be really miserable to use if you couldn't do that.

You can drag any unity object into a serialized field

[coarse compass]

An object yes, but not a component that sit on another object. boxfriend is saying that we can but I dont see how.

[languid spire]

a Component is an Object

[swift crag]

Are you trying to reference a scene object from a prefab?

we need more context

[swift crag]

what is it?

[coarse compass]

Isn't a component part of an object?

[swift crag]

No.

many things are unity objects

GameObject, MonoBehaviour, ScriptableObject, ...

[swift crag]

every Component must be attached to a GameObject

perhaps that's what you're thinking of

[queen adder]

No matter what i set the gravity scale to the bomb explosion makes the character fall at a really fast speed

[coarse compass]

Ha ok I thought object = GameObject, I come from Blender so that kind of made sense but I see the difference now.

[swift crag]

UnityEngine.Object is the big parent type.

[queen adder]

I know this is simple as hell but i can not figure out how to fix it

[languid spire]

also notice, I wrote Object, case matters

[swift crag]

and how does the bomb work?

sounds like you need to look at PlayerMovement, then

share the entire script in a paste site

https://gdl.space/iqepemuxoh.cs

[swift crag]

the player movement script, I mean

[queen adder]

https://gdl.space/oqireyoyat.cs

[swift crag]

If gravity scale isn't doing anything, then there must be something else changing the player's velocity

[coarse compass]

Ok I finally understand that by dragging a GameObject to a public variable initialized to a specific type it figure out by itself that I want the component of that type on that GameObject. Is that correct?

[queen adder]

I know im just sharing both for context

[swift crag]

Yeah, you can drag the GameObject in and it'll grab the first matching component

You can also drag a specific component, but that's more annoying, since you need two inspectors up (unless you're dragging between two things on the same GameObject)

[coarse compass]

Cool, thanks everyone

[swift crag]

I almost never store GameObject references

only when I literally just want to turn something on or off

[coarse compass]

Yeah it would have felt annoying to reference a GameObject and then have to get the component on that GameObject within the script

I'm glad this work this way it's much easier

[swift crag]

If your gravity scale is zero, you should just fly into the ceiling. Does this not happen?

[hidden sleet]

Yeah to kept trying to drag the actual script component from other game objects into the inspector, being able to just drag the object itself is a lot nicer

[queen adder]

Its the animation

I figured it out

[swift crag]

ah, yes, that'll do it

[queen adder]

Theres an animation event i realised once he was actually in the air

[plucky vapor]

I want to update the NPC's name with the name given to it. How do I do that?

This is the default

[hybrid tapir]

whats the playstations share button called in the new input system

[vast ivy]

my scriptable item script:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

[CreateAssetMenu(fileName = "Item", menuName = "Scriptable Objects/Item")]
public class ItemSO : ScriptableObject
{
    public string name;
    public string description;
    public Sprite icon;
    public GameObject prefab;
    public enum ItemType
{
    Resource,
    Tool,
    Weapon,
    Consumable,
}
    public int stackCurrent = 1;
    public int stackMax;
}

when an object is picked up using another script, it collects the ItemSO info on that item, which then I can add it to the inventory (have to remake this)

[soft steppe]

i dont have the skills to help you with this i just restarted making game with unity after a few months

[vast ivy]

yea im pretty new too, started maybe a week or 2 ago

simple 2d level manager for user made levels

[charred spoke]

Well for starters dont use binary formatter. Its deprecated by microsoft and poses a security risk.

[soft steppe]

anything else i shuld change?

[frosty hound]

Does this code work?

[short hazel]

Use using statements when dealing with file streams, so they're closed automatically even if you return early or an exception occurs

[soft steppe]

it worked years ago beford i abandoned the project

not years

[frosty hound]

So does the code work?

[soft steppe]

like 10 months

[soft steppe]

i can check

[charred spoke]

I cant compile the code in my head, if it works it works. You might want to look into using the adressables system rather than loading objects from the resource folder, use a proper GUID rather than a id in the name of the object and I dont like the _ in the method name since it does not follow convention

[hybrid tapir]

how do i have it log it just once and have it update the log msg for however many seconds the button is pressed

[frosty hound]

Also, you can have same named functions provided their parameters are different (as with your two LoadLevel functions)

[charred spoke]

You dont

[soft steppe]

i can give u the project folder but there is a huge amounts of problems with the plkayer movement

[short hazel]

Lambdas don't need braces where there is only a single instruction in them

SceneManager.sceneLoaded += (scene, mode) => _LoadLevel(scene, levelData);

[hybrid tapir]

dang

[charred spoke]

You can toggle collapse in the console window and then then same msg will have a counter

[soft steppe]

but anyway the only usefull part is loadlevel cuz the rest has security risks

[short hazel]

You also cannot unsubscribe the lambda from the event with -= as even if the lambda is written exactly the same, it's still two different instances of it

The unsubscription does nothing

[swift crag]

yes -- it does reference equality, iirc

I usually just write a named function at that point.

(it can still use the => syntax!)

Although, this won't work if you need to capture some local variables for that lambda.

[coarse compass]

How would you distribute points randomly on a mesh surface? I'm trying to spawn entities on the navmesh according to a set density per square meters. Is there a built in function for this somewhere?

I found this answer but this seem like a lot of code for something so ubiquitous in video games. https://community.gamedev.tv/t/good-way-to-dynamically-and-randomly-spawn-on-navmesh/230492

This makes more sense though: https://docs.unity3d.com/ScriptReference/AI.NavMesh.SamplePosition.html
Still it's not ideal but whatever.

[late burrow]

how do i make function that edits existing variable rather than putting it inside function

like string.replace

[short hazel]

Replace returns a new string, it does not edit the string you pass in-place

[late burrow]

yes just i put it variable.function not function(variable)

[short hazel]

The answer is, it depends on the type of the variable you need to modify

what

Well to be able to do that, you need to add the method inside of the type (in the class)

Then you'll be able to call it on an instance of that type

[swift crag]

doesn't seem like a ton of code to me

uniformly choosing from a point on an arbitrarily complex mesh isn't easy

You can pick a random triangle from the mesh and then pick a random point in that triangle

but that's biased towards small triangles

[timber tide]

technically how transform class works rather, more like matrix3x4 and using transpose and other similar methods. Self-modifying methods that would be private.

[swift crag]

I guess you could add up the areas of all navmesh triangles, then use those to do a weighted random choice

it's how a lot of things work :p

foo.Bar() is calling Bar on whatever object foo contains

[teal gulch]

probably https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/extension-methods

[swift crag]

Yeah, if you're asking how to add a method to an existing type, that's the way to go

[distant robin]

hi why unity keeps giving me this error? NullReferenceException: Object reference not set to an instance of an object
CollectableInteraction.StartInteraction (UnityEngine.Transform objectToInteract) (at Assets/CollectableInteraction.cs:64)
CollectableInteraction.Update () (at Assets/CollectableInteraction.cs:35)

NullReferenceException: Object reference not set to an instance of an object
CollectableInteraction.StopInteraction () (at Assets/CollectableInteraction.cs:88)
CollectableInteraction.Update () (at Assets/CollectableInteraction.cs:26)

my code works fine.

its very annoying

[coarse compass]

You could weight it by face area but yeah it gets complexe for no reason at this point. I think that's why everyone is just raycasting. Edit: nvm thats what you said just after lol

[timber tide]

vfx graph actually has a built in method called point caches but I'm not too sure of the usability out side of it

[swift crag]

Randomly picking points until once is on the mesh will give a uniform distribution, yeah

It'll also take a random amount of time, so it's not perfect

(we'd call this "rejection sampling")

[distant robin]

[distant robin]

i still dont understand how to fix that lol

[slender nymph]

what about that do you not understand

[slender nymph]

also don't copy the raw link when sharing these links

[distant robin]

i dont know how to fix the actual code https://gdl.space/uducayupoz

[swift crag]

did you go through all of the topics linked on that page?

read them.

[distant robin]

fixed that guys

thank yall

[hybrid tapir]

why doesnt this set it to 0.0?

[vast vessel]

hey guys. i have it if val1 or val2 are null my function returns false, but im still getting a null refrance exception. why is that?

[slender nymph]

because you immediately set it to Time.deltaTime in the next if statement

[hybrid tapir]

but it doesnt go back to 0 before starting again

[short hazel]

The log does that. It's before the if statements

[slender nymph]

because you immediately set it to Time.deltaTime in the next if statement. in the same frame

[hybrid tapir]

oh

how do i have it wait a few frames

[slender nymph]

if timer is true, set timer to false and timePassed to 0. then you immediately check if timer is false

[lofty sequoia]

If you Destroy() a gameobject that has child gameobjects, is Destroy called on the child gameobjects? Or are they garbage collected later on? What happens to the child gameobjects?

[vast vessel]

oh, sorry, guess my brain was also getting a null reference exception when searching for whats wrong in my code lol

[slender nymph]

they are destroyed as well, yes

[short hazel]

The stack trace includes the line number:

MemoryVariable.cs:10
Line 10. All that's left is to look at what's on that line

[vast vessel]

ill keep that in mind for next time. thx

[tall delta]

this check 'if (timePassed == 0.5f)' will never be true

[short hazel]

It can be true, but it's unlikely

[summer stump]

No necessarily never, but extremely inconsistent

[tall delta]

weeeeeelll ok, sure, some people do win the lottery

if you want to be pedantic about it 😄

[summer stump]

Way better odds than the lottery. It can be true pretty frequently actually

[hybrid tapir]

im trynna make it log it only every half a second

[tall delta]

that's not a discussion worth my time

[summer stump]

= if adding <= if subtracting
I never saw the actual code

[short hazel]

Haha actually you'll hit 0.5 if you get 30 frames at exactly 60 FPS, ignoring the float precision issues

[tall delta]

that's a big thing to ignore 😅 but yeah, the math works out

[swift crag]

It actually works out in your favor!

Lots of ways to wind up with exactly 0.5

[tall delta]

eh, maybe 10-15 ways? a trillion ways to not get it. also, you only get one chance to check, and that check is also based on user input

[hybrid tapir]

im trying to hold the button and have it only log once every half a second but this time its instantly going to 999

[timber tide]

ya need to add some time contraint otherwise you're probably logging every update loop

look up timer tutorials or how to set a cooldown

[tribal pendant]

do I need to open a ticket to ask a question?

[summer stump]

No. This is not an official support discord

[tribal pendant]

can someone help me figure out why the player's velocity gets set to 0 when i touch the ground after falling? and why I get stuck with my head when I touch the platform?

[slender nymph]

show your code

[late burrow]

i do be setting gravity to 0 when on ground so i wont be constantly rolling down on near flat surfaces

[tribal pendant]

i mean x velocity

[late burrow]

perhaps too low terrain bounciness

[tribal pendant]

this is the code, most of the variables are in italian tho , i can tralsate if oyu need claryfying

[tribal pendant]

how do i set it ? it's grayed out in the box collider

[late burrow]

make new physic material and drop it on collider material

[amber spruce]

public void TakeDamage(float damage)
{
    Debug.Log("TakeDamage");
    if (playerController.isBlocking)
    {
        damage = damage / 4;
    }
    else
    {
        currentHealth.Value -= damage;
        animator.SetTrigger("Hurt");
        Debug.Log(damage);
        if (currentHealth.Value <= 0)
        {
            Die();
        }
    }
}

so i get the first debug but i dont get the second anyone know why i also dont deal damage

[tribal pendant]

if i set the bounciness higher the player just keeps bouncung infinetly higher

[late burrow]

ofc

make it amount you need

[rich adder]

your else statement is never hit

[slender nymph]

if you do not get the second debug then either you are receiving an error or playerController.isBlocking is true

[amber spruce]

i tried without the else statement because i dont need that i only added it because it wasent working

[rich adder]

something is not working you just throw something else and hoping it works?

debug your original problem then

what does "wasnt working" mean in that context

[sage mirage]

Hey, guys! I don't know how to set my default screen resolution to my in game resolution when entering the game. How to do that because when I am entering the game I don't see my screen resolution. I made a dropdown for my resolution options and I save them and load as well but the only problem here is to load my default resolution, so the players screen resolutions to its default screen resolution of their monitor inside the game.

Check my code here:

{
    // Every variable or initialization that has to happen when the game starts in here!

    resolutions = Screen.resolutions;

    if (resolutionDropdown != null)
    {
        resolutionDropdown.ClearOptions();
    }
    
    List<string> options = new List<string>();

    for (int i = 0; i < resolutions.Length; i++)
    {
        string option = resolutions[i].width + " x " + resolutions[i].height;
        options.Add(option);

        if (resolutions[i].width == Screen.currentResolution.width && resolutions[i].height == Screen.currentResolution.height)
        {
            currentResolutionIndex = i;
        }
    }

    if (resolutionDropdown != null)
    {
        resolutionDropdown.AddOptions(options);
        resolutionDropdown.value = currentResolutionIndex;
        resolutionDropdown.RefreshShownValue();
    }```

[amber spruce]

like i didnt get the debug or take damage

[rich adder]

did you debug your playerController.isBlocking values

also i was talking about the issue before you changed it

[short hazel]

The stuff in the else only runs if the stuff in the if didn't run.
So if you have blocking enabled, you don't receive damage. You divide the value by 4, and execution exits the method without running anything else

Your code editor might even tell you that damage = damage / 4; can be removed as damage is never read after that

[rich adder]

I don't see any debugs here, that should prob be your first step

[short hazel]

Online compiler does it, so your code editor will also tell you:

(code adapted to compile without Unity)

[amber spruce]

well i know that the blocking is false

because if its true it has a animation

[summer stump]

Terrible way to do that. The animation transition may be broken, or the logic isn't quite what you expected, or something else.
Use debug.log or a debugger. Distrust EVERYTHING else

[amber spruce]

yeah but wouldnt just removing the else fix the whole problem with the if else

[sage mirage]

Yes, I mean how to set my resolution when the game starts like when Made with Unity is showing up to my monitor resolution? Because when I start the game it doesn't set my monitor resolution to the game resolution. I was wondering if I have to use something like Screen.SetResolution() on the awake function?

[summer stump]

Maybe, maybe not.
You tell us, IS it fixed?

[amber spruce]

well it didnt work before

[summer stump]

That's not what I asked.
Does it work now

[rich adder]

its possible but first make sure, is the function even working as is ?

https://docs.unity3d.com/ScriptReference/RuntimeInitializeLoadType.BeforeSplashScreen.html
its an attribute
https://docs.unity3d.com/ScriptReference/RuntimeInitializeOnLoadMethodAttribute.html

[amber spruce]

no

[summer stump]

Then removing the else didn't fix it, right?

[amber spruce]

no it did not

[short hazel]

Isn't that the default behavior? When you run the game for the first time the default is to fit to the screen, no?
In the past there was the launcher window where you could change the quality and resolution, but that's gone now. I'd check your project settings

[amber spruce]

i found the issue

public void TakeDamage(float damage)
{
    Debug.Log("TakeDamage");
    if (playerController.isBlocking)
    {
        damage = damage / 4;
    }
    Debug.Log("damage: " + damage);
    currentHealth.Value -= damage;
    Debug.Log("currentHealth: " + currentHealth.Value);
    animator.SetTrigger("Hurt");
    Debug.Log(damage);
    if (currentHealth.Value <= 0)
    {
        Die();
    }
}

i get all the debugs up till after i change the health value

[sage mirage]

So, how to use that attribut?

[rich adder]

did you look at the second link ? it shows how

[summer stump]

So, you still get the first debug and not the second.
Can you show the whole current code

[short hazel]

Do you get errors in the console? Code doesn't stop executing out of the blue like that! Make sure errors are enabled in the console

[sage mirage]

So, I have to make a method and before that method to add that attribute is says?

[rich adder]

using UnityEngine;

class MyClass
{
    [RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.BeforeSplashScreen)]
    static void OnBeforeSplashScreen()
    {
        Debug.Log("Before SplashScreen is shown and before the first scene is loaded.");
    }
}```

[sage mirage]

I was always working with methods I dont know what those attributes is, I had no time to work with them and learn them actually.

[rich adder]

you never used SerializeField ?

thats an attribute

[sage mirage]

I have used

Serialize is an attribute right

[rich adder]

it usually goes above class/method/member var

[sage mirage]

ok!

[rich adder]

https://docs.unity3d.com/ScriptReference/Serializable.html
this one you mean or this one
https://docs.unity3d.com/ScriptReference/SerializeField.html

[sage mirage]

There is no method for that functionality? I mean there are only attributes?

[rich adder]

the attribute is what tells the method to run before scene load

[sage mirage]

I was searching for OnApplicationEnter maybe but there is no method called like that XD

[rich adder]

but as SPR2 mentioned, resolutions is usually set to default when running the app first time no?

[sage mirage]

Oh, it seems cool thanks for the information!

[rich adder]

unless you changed it in Player settings

[sage mirage]

Here I mean the second one the field one

[coarse compass]

Why do people use Empties as root in Prefabs? This seems so bad to access Components or public variables on scripts

[lavish roost]

Its to Split Logic from visuals for better structure

[sage mirage]

@rich adder Do we use attributes only for static members?

[rich adder]

how does that at all affect anything (variables and components)

the components actually go on the root

only GFX get split up

[short hazel]

Ever used [SerializeField]? You have your answer

[rich adder]

apparently they have and still asked 😆

[lavish roost]

You can Access all the components If you need them

With a serialize field or GetComponentInChildren

[coarse compass]

What about colliders. Do you leave them on meshes?

[rich adder]

if its a mesh collider I usually do, esp if my mesh has resizing

otherwise you get bad sizing

simple shapes i keep on root

so i just modify their size with gizmos

[short hazel]

Also helps keeping uniform objects when the prefab is rotated. If you try to do that with a root object that's scaled, it will seriously affect its children

[quick ruin]

how do I fix this

just trying to set material alpha

[slender nymph]

https://unity.huh.how/compiler-errors/cs1612

[short hazel]

Store the whole color in a variable, modifiy its alpha, then assign the whole color back to the material

[quick ruin]

ty

[visual hedge]

So I can't serialize this one that easily, right?

[rich adder]

what is "this one"

prob screwed with the reference types

[visual hedge]

This one is the list of quite a data... so I can't just give the refference to the list to data saver and hope it will just save it?

[quick edge]

Yo! I have a problem. I have an empty game object (a pivot) and I childed a Camera on it. When I'm not in play mode, when I rotate the pivot the camera rotate around it like supposed, but when I'm in play mode it doesn't work. I don't understand why it makes no sense, and I didn't find any solutions on the internet. Can you help please?

[north kiln]

(don't scale mouse delta by Time.deltaTime)

[quick edge]

Why ?

[rich adder]

References afaik are a pain to save

could be wrong
maybe use scriptable objects??

[north kiln]

https://unity.huh.how/input/built-in-input/mouse-delta-time

[quick edge]

Ok interesting thanks!

And do you have a solution for my problem?

[rich adder]

Addressables are prob an option too since that assigns an actual address to the asset @visual hedge

I have to look back into its been a while xD

[visual hedge]

sorry, I think I might express myself wrong:
I have a list of different type of data, here's the screenshot.
And to save that list, I just be like:
public List<CapturedPets> summonList = new();
summonList = character.summonHandler.SummonList;

[rich adder]

sorry so whats the problem? is it not serializing ?

[visual hedge]

I guess I may have done something wrong anyways but it seems it doesn't save... throws a long error in the console.

[rich adder]

what is the error?

[visual hedge]

1 min, let me try once again 🙂

[vocal sail]

C# question here:
Does children classes inherit the complete classes' methods without overwrite it from the abstract class? If not, what should I do to accomplish this?

[rich adder]

its probably GameObject ? idk if unity likes saving it @visual hedge

[short hazel]

Yes, they do, as long as the methods themselves are not abstract (the compiler will force you to override them in the derived class anyway)

A child class has access to all its base members, provided that they're accessible (protected or more accessible)

[quick edge]

And the script is on the pivot

[vocal sail]

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public abstract class SceneObject : MonoBehaviour {
    
    public int sequenceID;

    private void Start() {
        gameObject.GetComponent<MeshRenderer>().enabled = false;
        gameObject.GetComponent<Collider>().enabled = false;

        MainProgressManager.mainProgress.OnNPCArrive += Called;
        MainProgressManager.mainProgress.OnSelfDestruction += SelfDestruction;
        MainProgressManager.mainProgress.OnStartUp += StartUp;
        
    }

    public void StartUp() {
        if (sequenceID == 0) {
            gameObject.GetComponent<MeshRenderer>().enabled = true;
            gameObject.GetComponent<Collider>().enabled = true;
        }
        else {
            gameObject.GetComponent<MeshRenderer>().enabled = false;
            gameObject.GetComponent<Collider>().enabled = false;
        }
    }

    public void Called() {
        int progressPhase = MainProgressManager.mainProgress.progressPhase;
        if (progressPhase == sequenceID) {
            gameObject.GetComponent<MeshRenderer>().enabled = true;
            gameObject.GetComponent<Collider>().enabled = true;
        }
    }

    public virtual void SelfDestruction(int progressPhase) {
        if (sequenceID < progressPhase) {
            gameObject.SetActive(false);
        }
    }

}

[visual hedge]

okay, I guess it doesn't ) thank you

[vocal sail]

here is my abstract class, so that my child classes will automatically have the called and startup methods subscribe to the actions? Because it seems that it is not the case or I'm doing something wrong

[short hazel]

If the child also declares a Start() method, the base will not be called. Make it virtual and call it in the override

[rich adder]

there are a couple threads on this subject, afaik if you need to save GameObject reference something is wrong with the structure

[vocal sail]

oh I see, that is the problem my Start() method in child overwrites it.

[visual hedge]

wrong is the fact that I am noob 🙂 And I try my noobish approaches and well... that leads to problems

[vocal sail]

So make the base method virtual, when my child override the method that will be addition to the method, right?

[knotty gust]

whats the difference between writealltext and writealltextasync?

[rich adder]

haha we live n we learn

[rich adder]

one is async and one is not

[short hazel]

Yes, just make sure to call base.Start() in the override. Your code editor will add that automatically, don't remove it in your case

[knotty gust]

yh but what does that mean in use lmao

[rich adder]

better question you should ask is , what is async ?

[knotty gust]

yhh

[visual hedge]

I got rid from game objects in that list and still got an error...

[knotty gust]

sorry

[visual hedge]

so I guess saving the list as a list is bad idea in general

or something...

[rich adder]

async is when you want the code to run parallel to other code or in the "background"

so it doesn't block the main thread

eg if you have a long list of stuff to get from the internet, you don't want your UI locking up while loading all that data downloading

so think of it as "run this in the background"

Writing to a file can also take time so its best to use async to not lock up the UI

most UI in any app run on the main thread

[knotty gust]

i see

thats useful

thanks

[wanton hearth]

OK this is likely a dumb question, but how can you easily view the position of each vertex of a mesh?

I want to look at a mesh and know, mesh.vertices[0] is here, mesh.vertices[1] is here, etc.

[austere osprey]

so i have a piece of code that is supposed to launch the player backwards and a little bit upwards upon dying, as well as rotating the player 90 degrees. i think it might work for the most part, but the problem is that the player proceeds to clip through the ground when flipped, and i don't know why. the game is in 2d

if (isFacingRight) { rb.AddForce(Vector2.left * 15, ForceMode2D.Impulse); rb.AddForce(Vector2.up * 10, ForceMode2D.Impulse); transform.Rotate(0, 90, 0); } else { rb.AddForce(Vector2.right * 15, ForceMode2D.Impulse); rb.AddForce(Vector2.up * 10, ForceMode2D.Impulse); transform.Rotate(0, 90, 0); }

[rich adder]

they're pretty useful the more you get comfortable with them, ofc you don't want start using it everywhere because you run into other problems

[knotty gust]

Yhhh I’m thinking to use it for my save system for now and since that’s the only place I would really be writing any data to a file I think it would be useful

[vocal sail]

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PathObject : SceneObject {

    private NPCManager nPCManager;

    public override void Start() {
        nPCManager = FindObjectOfType<NPCManager>();

        MainProgressManager.mainProgress.OnCallNextPath += ReturnPath;
    }
    public void ReturnPath(int progressPhase) {
        if (progressPhase == sequenceID) {
            nPCManager.moveTo = this.gameObject;
        }
    }
}```
but still the gameobject attach to the child script doesn't disable its visual on Start()

[short hazel]

You missed calling base.Start() -> #💻┃code-beginner message

[rich adder]

Yeah writing to files is def good use of async since it can take a second or maybe more depending on amount of data and other factors

[vocal sail]

oh adding base.Start to the front

yes, it works, thanks

[rich adder]

unity has an entry point for async in awake too, which is useful @knotty gust

[knotty gust]

Wdym?

[knotty gust]

What other factors would affect it if you don’t mind explaining

[rich adder]

you know the method Awake ?

[rich adder]

 private async void Awake()
    {
        await Task.Delay(1000);
        //wait a second and move on
    }```

[knotty gust]

Ohhhhh fr??

[rich adder]

the amount of data you're writing, hard drive speed anything that can affect writing to a file

[knotty gust]

Damn so I didn’t have to use a coroutine for delays on awake?

[knotty gust]

Ohhh ok that makes sense

Thank you

[rich adder]

depends, usually best to use Coroutines because they are already part of unity workflow

Coroutines are poor mans async

[knotty gust]

Makes sense looking at it now

So when would using async awake be better than coroutines?

[rich adder]

if you're for example doing an Init operation from the web

[knotty gust]

Yhhh I’m Ngl idk what an init operation 😂

[rich adder]

like cs private async void Awake() { await LoadSaveClass.LoadSomeWebData() }

[knotty gust]

Ohhhh

Getting data from the web basically?

[rich adder]

not only but thats a pretty common usecase

since data from web is not instantanious usually

[knotty gust]

Why’s it better to use async awake for that?

Yh I thought it would be Smth like that

[rich adder]

Like I said earlier, so your whole application doesn't lockup while fetching data

particularly UI

[knotty gust]

Nooo I meant over a coroutine

Or is it the same thing

Like same reasoning

[rich adder]

yes

they're both async methods

unity recommends using this though when using async
https://docs.unity3d.com/2023.1/Documentation/ScriptReference/Awaitable.html

[knotty gust]

Ahh okay okay

Thanks man

[upbeat stirrup]

Should I use Rigidbody.velocity or Rigidbody.AddForce() when making a movement system? I know you shouldn't change the velocity directly, but I see it being used in movement systems a lot.

[summer stump]

Why do you think you should not set velocity directly?
And use either.
Try both and see which feels right to you. They can feel fairly different, so it depends on the game

[upbeat stirrup]

Thanks a lot! Also, unity docs states, "In most cases you should not modify the velocity directly, as this can result in unrealistic behaviour - use AddForce instead..."

[short hazel]

If you make unrealistic movements (too realistic is sometimes bad) it's perfectly fine to change the velocity directly
What's not fine is changing the transform.position directly with a Rigidbody on, it ingores the physics system!

[amber spruce]

anyone know what this error means

InvalidOperationException while executing 'performed' callbacks of 'Player/Attack[/Mouse/leftButton,/XInputControllerWindows/buttonWest]'

and can i ignore it or no

[rich adder]

are you using new input system

[amber spruce]

yeah

[short hazel]

This error will be paired up with another error in the console usually

[rich adder]

seems like something u should not ignore then

[amber spruce]

it is paired with another errror

[rich adder]

ahh

yes

clients cannot write to Network variable

unless you set permissions to all

idk how thats related to input tho xD

[amber spruce]

i didnt think network variables could have perms set to all

[short hazel]

New Input System also catches the errors that happen in your event handlers, so they're reported twice.
Once for the exception itself caught by Unity, and once for the Input system itself catching it

[amber spruce]

and im not im using a serverrpc

[summer stump]

Well, that is fair then haha. Setting velocity is pretty common though

[cobalt solstice]

If I've used an image from somewhere that requires attribution in the project is there a suggested place for that kind of thing? This is an academic project so I've got to write a documentation too if that kind of thing can be linked in the written part if anyone knows?

[rich adder]

yes. example
public NetworkVariable<ulong> ReconnectionKey = new NetworkVariable<ulong>(default, NetworkVariableReadPermission.Owner, NetworkVariableWritePermission.Server);

[upbeat stirrup]

I see, thanks!

[amber spruce]

i fixed it i forgot to change the write perms to server

[rich adder]

text file in the final build should suffice

[cobalt solstice]

Of the unity project?

Or the documentation

[rich adder]

depends what you're distrubuiting
if the image is part of the docs then yes link to original license/attribute

[cobalt solstice]

Ah I'm using it in unity rather than the doc so I wasn't sure where to put the link

[rich adder]

in the final build folder with exe, as a text file or if you want a Credits page on your app

[cobalt solstice]

Ah alright cool Ty 🙂

[cobalt solstice]

Sorry quick question with that first option, is that bit when you go through the build settings?

[rich adder]

no I mean just make a text file like you would any other way, paste the link and attribution there

[lime mural]

can't you just flip the sprite? And also, I think you can just make isFacingRight and int and multiply Vector2.Right by it

[rich adder]

then when you build the game , put that inside the build

[cobalt solstice]

Ohh gotcha

Ty

[hybrid tapir]

how do you prevent the default action for gamepad buttons

[low perch]

Unity is not in play mode but I am getting this like every frame

NullReferenceException: SerializedObject of SerializedProperty has been Disposed.

[wintry quarry]

Probably an editor bug

[uncut dune]

Ignore and move on unity does that sometimes

[low perch]

ok

[rocky canyon]

dont ignore it, just restart it

it'll vanish until the editor bugs out again

usually you can spot unity errors by the way they are..

they'll usually have a specific namespace

like Unity Editor. blabla

= editor bug (not ur fault)

unlike the previous error (this one is ur fault)

[slender nymph]

that's not always the case though. for example, writing editor code could lead to UnityEditor related errors

[rocky canyon]

thats true..

but if its an unusual error.. (ur not working with editor scripts etc) + seeing that library.. then most likely bug

gyro and accelerometers are both inputs i can use w/o having that allow permissions pop up?

getting started with mobile and walking into a whole new world 😅

[low perch]

I restarted it and found out it happens after I exit playmode every time I add/remove an inventory slot.
When an inventory slot is added (ex: from 1 to 2) I have a set thing that updates inventoryLimit = value and also calls updateInventorySlots() which I suspect is the issue however the methid is called on awake and has no issues when I exit playmode. I wrote no editor code either

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

[deep quarry]

Hey,
This is my code to move my character:

moveDir = transform.forward * vertical + transform.right * horizontal;

rb.AddForce(moveDir * moveSpeed * Time.deltaTime, ForceMode.Force);

I get this message above the moveDir on the second line:
Re-order operands for better performance

How may I re-order the code to get better performance?

[low perch]

I believe vectors should be multiplied at the back and floats at the front

[rich adder]

i think u can just do rb.AddForce((moveSpeed * Time.deltaTime)* moveDir , ForceMode.Force);

IDE iirc will help you do it

[deep quarry]

Ohh, I see. That actually makes sense.

Thank you very much, both of you! :)

[visual hedge]

general question: Is someone doing like mentoring / teaching about unity stuff?
Basically what I mean is theoretically me hiring a mentor that will help me with solving different problems with my project on request.
That's not a hiring message. I am just curious if something like that exists.

[low perch]

fiverr

[visual hedge]

oh, thank you. Have to check that resource

[ionic zephyr]

what does "Monobehaviour" do?

like what´s it´s purpose

[timber tide]

it makes game

[rich adder]

perhaps look at the documentation ?
https://docs.unity3d.com/ScriptReference/MonoBehaviour.html

[summer stump]

It gives you access to properties and methods from that class and the ones it inherits from.
Standard OOP

[teal viper]

It's like your little custom component.

[ionic zephyr]

What does inherit mean exactly in coding context

[summer stump]

You should definitely look that up
It is a very basic concept in coding. It is a foundation of Object Oriented Programming

[summer stump]

You might want to take this basic c# course. It is very good and goes over inheritance

[dreamy epoch]

Hey there! I am trying to use the Rewired API to take in inputs from a Logitech G290 steering wheel and cannot get the steering wheel to cooperate. Any suggestions or better place to get info? Thank you so much!

[robust condor]

Do mesh collider vs box collider performance matter if nothing is colliding with the objects? If I spawn 1000 objs that really wont collide with anything

[timber tide]

mesh requires more operations to check collision, and it's concurrent so it doesnt matter if it's not colliding

[hushed rose]

I have ~ 4k terrain trees on map. I want save info about each of them (position, rotation etc), then remove and Instantiate prefabs on their position - any advice to performance?

[arctic harbor]

trying to set some default values for some variables within the script in case i forget to manually adjust the values in the inspector. for some reason if i have leftLimit declared first, the default value for rightLimit set via script seems to be ignored in the editor, but if i declare rightLimit first, it seems to be fine. why is this so?

[north kiln]

how are you testing default values; because unless there's an extreme bug I doubt this is actually happening

[timber tide]

You could just try loading them in and disabling them until you decide you want to render them. I think they are still statically batched in this regard, otherwise you'd have to dynamically batch them if you choose to load them later on at runtime.

[arctic harbor]

well i'm just doing this. i want to horizontally clamp camera movement (i've done that later in the script)

[north kiln]

Are you resetting the component via the context menu to see the default values in the inspector?

[arctic harbor]

oh that works thanks. not sure why rightLimit was going to zero when declared second though

[north kiln]

(also those are some bizarre magic numbers to use for defaults)

[arctic harbor]

well, the decimals specifically is so i can have the walls snug against the sides of the screen

the 999 part of rightLimit is just some arbitrary large number that probably won't be reached

[robust condor]

There are better ways to do this

[arctic harbor]

i'm sure there are, but this is working and simple enough

[deep quarry]

Hey,
Quick question. I am making a Player Controller script based on Rigidbody.
If I want to rotate the Player, can I use the transform.Rotate() method or should I use a Rigidbody based rotation, such as Rigidbody.MoveRotation?

[teal viper]

You should use rigidbody based rotation.

[deep quarry]

Perfect. Thanks!

[boreal tangle]

Is it worth it to restart the script for player movement if the code is messy and only works 95% of the time.

[rich adder]

refactoring is important sure

[boreal tangle]

Okay thank you

I don't know why I get this mistake if you can help me, making the text big when you enter and get little when you already enter the screen but this comes out

[summer stump]

You enable it, start a coroutine, then disable it all in one frame

A coroutine only makes the code INSIDE it wait, nothing else

[last grove]

ohhhhhhhhhhhh

that would make a lot of sense

You have LeanTween imported?
Never used it, but are you sure that is the Namespace you need?

[spiral glen]

Is the access to Animator, Vector2 and Rigidbody2D aggregation, composition or neither?

[north kiln]

Is this a test 🤔

[spiral glen]

Yes, maybe? idk, I just need to figure this out

[rich adder]

whyare you using notepad++ lmao

[frosty hound]

Figure this out ... for a test?

[spiral glen]

No It's not for a test

So are they composition, aggregation or neither. I'm trying to figure this out.

[supple wasp]

It is the only one that goes fast the visual studio 2017 sees slow and says that it does not respond

[rich adder]

even 2017 is outdated as hel..use 2022 VS
2022 is faster cause its a 64x bit application

[spiral glen]

Should I ask this in the general or advanced or something, I need to figure this out by saturday.

[supple wasp]

I will be able to use the unity and the visual Studio 2022 well when my improved new laptop arrives

Well there are the mistakes that come out

[north kiln]

Why would you need to figure out something so banal if it wasn't for a test?

[spiral glen]

Because I have coursework due on the 15th and my plan includes finishing this part by the 6th.
This part includes figuring out if these three variables are aggregation, composition or neither so I can change the title and/or remove it before I begin typing it out. (As I can't talk about aggregation if it's composition)

[rich adder]

and the package is installed?

btw DOTween highly superior Imo

[north kiln]

maybe I shouldn't have been specific and just asked if it was for homework; because it's obnoxious as hell to be asked multiple-choice questions

[spiral glen]

So... any clue on the answer?

[slender nymph]

have you considered reviewing your course materials to find the answer?

[supple wasp]

What pack of unity?

[spiral glen]

I have, I know what aggregation and composition is but the actual application in figuring out if something is or isn't either is confusing.

I mean I guess aggregation is dependancy so I'll just call it that and stop flooding chat, gracias.

[swift crag]

these are nitpicky OOP buzzwords. very annoying to think about

[rich adder]

the package ur attempting to use

[supple wasp]

But what package?

[north kiln]

it's a mystery

[rocky canyon]

Unity comes pre-packaged with many things..

like these two...

NaughtAttributes is not default

i'd have to install that

[supple wasp]

I just put the unity package and now

[rocky canyon]

for you the error is Under "LeanTween"

i wonder wat package its expecting..

[rich adder]

GPT code 💯

[rocky canyon]

https://assetstore.unity.com/packages/tools/animation/leantween-3595

look at this.. its in the Unity Asset Store..

if u check the Documents it shows all these parameter's and functions each one is following a LeanTween.

thats what the using LeanTween means..

it means when u call any of these. it knows where to look.. until you install it.. it doesn't exist

[rocky canyon]

and yes.. DOTween is better IMO.. and it has pretty much identical features

[abstract pelican]

tell me how I should be here?

[swift crag]

It's just suggesting that you use those two newer methods.

The old one will continue working (for now, at least)

[summer stump]

SoundManager sounds like a fine thing to make a Singleton with a static accessor though, negating the need for a Find call

[amber spruce]

 SamuraiButton = GameObject.Find("SamuraiButton").GetComponent<Button>();
 KnightButton = GameObject.Find("KnightButton").GetComponent<Button>();
 WizardButton = GameObject.Find("WizardButton").GetComponent<Button>();
 ButterButton = GameObject.Find("ButterButton").GetComponent<Button>();

why doesnt this work they never get assigned to stuff

[slender nymph]

check your console for errors

[abstract pelican]

when I create a singleton in it, for some reason the music stops playing

[nimble apex]

this should relate to code , sorta UI design

my team is using a pretty bad UI deisgn rn, basically we call and stack UI one by one, so in order to make thing less chaotic, we will put a panel for the top UI

[summer stump]

What do you mean "in" it?

[nimble apex]

so it will hide other UI under it

[abstract pelican]

Is there something wrong here?

[nimble apex]

but now every UI is calling a panel, too many panel stacking is not good

is there a way , to allow only one panel exists, but that panel can always under 1 level of the top UI

for example

[abstract pelican]

@summer stump

[nimble apex]

UI 1 top
panel
UI 2 bottom

UI 1
panel
UI 2
UI 3

without calling gameobject.findbytype

or get componentbychild

[cosmic dagger]

You're adding an AudioSource component for every sound you have on one GameObject, why?

[abstract pelican]

soundManager.PlayClip("Backpack close");```

and that's how I add where I need to

[cosmic dagger]

I understand the array of Sound, but why add an AudioSource component for every single sound? Say you have 100 sounds; youre adding 100 AudioSource components to the sound manager GameObject . . .

[summer stump]

I generally do the reverse:

public static SoundManager Instance { get; private set; }

    void Awake()
    {
        if (Instance != null)
        {
            Destroy(gameObject);
            return;
        }

        Instance = this;
    DontDestroyOnLoad(gameObject);
    }

But that should be fine.
Is it getting destroyed though?

Also note that the static variable (where you put the //singleton comment) is not the singleton, the class is. A singleton doesn't even necessarily need the static accessor

[cosmic dagger]

You can replace the properties of an AudioSource with the fields from the Sound instance before playing the clip . . .

[boreal tangle]

Does dependency injection mean using serialize to add the reference to a script?

[slender nymph]

that is a basic form of dependency injection, but is not the only form of dependency injection

[boreal tangle]

do you know a place I can see the diffrent ones

[swift crag]

it's a very broad concept

it's really just when you give something another object, instead of that thing having to create its own object

[slender nymph]

dependency injection is just the concept of injecting a dependency into an object. this can be done any number of ways. you can do so by simply assigning a reference via the inspector, pass a reference to an object via method parameter or directly assigning to a property/field, use a full on dependency injection framework, etc

[swift crag]

if you want to give yourself a heart attack, look at the readme for Zenject

[boreal tangle]

ok thank you

[cosmic dagger]

Oh dear, not Zenject . . .

[abstract pelican]

I took it from some kind of lesson

[swift crag]

you have written a local function called Awake and stuffed it into your Awake method

[abstract pelican]

sorry, Thanks, I didn't even notice.

I was trying to make some kind of general sound manager for each object so that I could then turn down the sound for all of them with one slider

[swift crag]

You should look at sound mixers.

You can route all of your audio sources into a mixer and then control its volume

[abstract pelican]

Now I can't find the sound, as it was before

everything works fine with this

[abstract pelican]

but don't you need such managers?

maybe there is some great video? So that I can get rid of him

[slender nymph]

i mean you don't need a sound manager. especially not to just easily control the volume of a group of different sounds

[abstract pelican]

I just don't understand where to store the sounds.

[summer stump]

Do that in Start. Instance is set on Awake, so you're grabbing the reference too early

[slender nymph]

although apparently audio mixers don't work in webgl so that's a consideration

[abstract pelican]

how do they do it in large expandable projects?

[slender nymph]

do what? because it seems like we are referring to different things

[swift crag]

aeugh

[abstract pelican]

I don't have a webgl.

[abstract pelican]

okay, thx

[slender nymph]

then that concern is not relevant and you can use audio mixers all you want

[abstract pelican]

yes, nice work, ty bro

[cosmic dagger]

Use audio mixers, for sure. You place a reference to an audio mixer inside of an AudioSource component. Any AudioSource linked to that mixer will use its settings . . .

[slender nymph]

this is why i use the secret __internalAwake for my singletons

[abstract pelican]

I'm sorry, of course, but as a beginner, can you tell me if I need this sound manager?

[swift crag]

let me ask you a question

why do you think you need a sound manager?

[abstract pelican]

as they usually do in large projects so that I can expand it later without rewriting the code

I just now noticed that it creates 5 audio tracks

even opening the inventory, although I didn't use it

[slender nymph]

wdym it creates 5 audio tracks? or are you referring to the 5 different AudioSource components? because that has been the concern everyone else has been pointing out this entire time

[abstract pelican]

no, I didn't point it out as a problem, I didn't even notice it, someone wrote to me in a chat about it why do you need so many tracks

I decided to check if it was true.

[slender nymph]

that's the whole point of this entire conversation. have you just not been paying attention?

[cosmic dagger]

This is what I mentioned earlier. Your code adds an AudioSource component to the GameObject for every Sound in your array . . .

[abstract pelican]

the point of the conversation was that I couldn't find a replacement for findtupe in the new version of unity, I tried singleton but it gave me an error

[abstract pelican]

maybe it was you, I didn't remember the nickname who told me about it.

[slender nymph]

i'm referring to everything after that part. you know, where everyone is trying to find out why you need a different AudioSource for each sound clip and the entire point of the soundmanager in general

[cosmic dagger]

You only need an AudioSource for each type of sound, like: background music, sound effects, dialogue, and UI . . .

[abstract pelican]

could you tell me how to do it better, because I will have flexible sound settings for each, such as music, sounds, environment and UI

[neat bay]

does anybody know why this while look crashes my unity?

[slender nymph]

because its condition never changes

[neat bay]

1 / cooldown * elapsed <= 1

this?

[abstract pelican]

I thought it was convenient to just add this to the code soundManager.PlayClip("Backpack close");

[slender nymph]

yes. you probably don't even want that to be a while loop, unless you want to change this to a coroutine with a yield return null inside the loop

[swift crag]

this is anti-good. you're using a string to play a clip. if you change the name of the sound clip, all of your existing code breaks

[abstract pelican]

I didn't understand you a bit, what do you mean

[swift crag]

I am working on a reasonably sized game that's been pleasant to develop so far. Perhaps you'll be interested in how I'm handling sound in it

[abstract pelican]

yes, because of this, there was a check

[neat bay]

what should it look like then?

[swift crag]

I have an AudioSource on each "thing" that can produce sounds. Each thing will either directly reference AudioClips or reference another asset that holds AudioClips.

[abstract pelican]

Of course bro I'm interested

[swift crag]

Each AudioSource has a sound mixer set on it to route the sound to the correct category

[abstract pelican]

I'm always glad if someone shares their cool experience.

[slender nymph]

either not a while loop and simply just an if statement and you call the method every single frame or make that method a coroutine like i suggested

[swift crag]

Ambient/Speech/SFX/Music/etc.

[swift crag]

I sometimes have multiple audio sources. I do this if I need continuously-playing sounds

[abstract pelican]

could you show a screenshot of how it looks on the object

[neat bay]

ok I'll try it out, thanks

[swift crag]

e.g. a computer has a looping fan noise and also randomly plays beeping sounds

that'd be two audio sources

[swift crag]

There's nothing really special here. I just have an AudioSource on the same object as the component that wants to play audio.

The game also has a hand-rolled spatial audio system that tries to add reverb and adjust the position of audio to sound more realistic...but that's out of scope 😉

[abstract pelican]

look, for example, I have an inventory, how do I put two closing and opening sounds on it?

[swift crag]

Give the inventory component AudioClip fields for the opening and closing sounds

[neat bay]

wait actually I don't understand, how does this condition never change?

[swift crag]

and give it an AudioSource component that it references

[gaunt ice]

1 / cooldown * elapsed <= 1
```this line shouldnt freeze your unity btw since the elapsed is incremented by time.deltaTime, the only reason casuse the line of code always false is 1/cooldown=0 (cooldown=infinity ?)

btw 1/infinity will not give you segfault and crash your unity

[north kiln]

it's a while loop without a yield in it

[swift crag]

[SerializeField] AudioClip closeClip;
[SerializeField] AudioClip openClip;
{SerializeField] AudioSource audioSource;

[abstract pelican]

yes?

[north kiln]

whatever it does it will execute instantaneously. You have to ask why it's a while loop in the first place

[abstract pelican]

okay, thx

[neat bay]

cooldown = 0.7 in my inspector though

[cosmic dagger]

Use the method that Fen is using. That's exactly how I've set my up before (minus the cool hand-rolled spatial stuff) . . . 😔

[swift crag]

The loop shouldn't freeze Unity forever.

It will just execute all of its iterations instantly

[north kiln]

If Timescale is 0

[abstract pelican]

okay, ty

[swift crag]

True. Or if it happens in a frame with a deltaTime of zero

I know turning on the recorder causes one of those.

[neat bay]

cause I want the code to repeat until the condition is met

[north kiln]

Instantly?

[swift crag]

Do you want every iteration to run all at once?

[abstract pelican]

ty bro

Thanks guys, I would have sat there and continued to be stupid.

[swift crag]

I wish I could just use Steam Audio...

(it does not work on ARM hardware)

[neat bay]

how do I make it not run instantly then?

[abstract pelican]

steam audio?

[gaunt ice]

someone has already told you use coroutine

[north kiln]

Use an if statement in Update, keep the while loop but use a yield in a coroutine, or await in an async function

[slender nymph]

i'd be interested in hearing more about that spatialization. i've been testing out steam audio but i cannot for the life of me get it to actually sound good, but i'm also not very smart when it comes to audio stuff 🤷‍♂️

[swift crag]

I'm approximating how sound travels using a nav mesh surface

I calculate a path from the source to the listener and compare its length to the straight-line distance

I also count how many corners the path has and how sharp they are

[neat bay]

Ok ill try it out, thanks for the help

[swift crag]

That's used to compute a "directness" value

Low directness causes the audio source to get a strong reverb and low-pass filter applied to it

I also shoot a raycast and cut the directness if it hits a wall

[summer stump]

That is SO SMART! I love it

[swift crag]

I measure paths from a few different positions to help blend it better as well

The more difficult thing I then do is actually reposition the audio source

I still need to work on that logic. I forget exactly what I did, actually...not at my laptop right now

I think it does a weighed average of the path points and slaps the audio source there

[calm coral]

Keep in mind even if you call flap() every frame, because you have while loop inside, it's going to infinitely loop after first frame, so the next frame will never come because it's infinitely looping inside your while
Tbh never mind, I am confused by this code because I don't see where flap() is being called

[swift crag]

heavily weighing the points closer to the player

I originally wanted to compute a graph of 3D volumes (so, box colliders) and do A* to navigate from the source to the listener

I might try that again, but having unity make the navmesh and do the pathfinding for me is pretty nice...

[cosmic dagger]

I can see doing that in order to get a direct"ness" value. That's where I got lost because I didn't know how to handle altering the sound based on that value . . .

[swift crag]

Try finding a loud, noisy thing that's got some obstacles around it

like, in real life 😨

listen to how the sound changes as you walk behind obstacles

you'll get a low pass filter (high pitched sounds go away)

fountains are a good source of noise. i notice the effect when i walk past a wall

Then you mix in reverb. The more indirect the path, the more reverb you want to mix in

more wet, less dry

wet = the result of the reverb filter, dry = the original audio

[gaunt ice]

high frequency (low period) signal not easily bend?
completely forgot the physics term

[summer stump]

Any consideration for surface hardness in your system?

[swift crag]

No, I'm not considering that at all. I guess I partially account for that with audio reverb zones

I'm not doing a lot of clever stuff that Steam Audio is

[summer stump]

They attenuate more strongly on reflections, while low-end frequencies retain more of their power. So it's not about the spread (or bend as you say), but the build up of reverberation and possible standing waves (which are less likely in high frequencies due to their wavelength being so small).
So in essence, the direct sound is blocked. The early reflections contain less high end, the reverberant sound is going to contain WAY less high end.

[swift crag]

due to physics

✨

I need to revisit the system. I wrote it almost a year ago :p

[boreal tangle]

would zenject be a good idea to learn or is it better to just used unity's serialize

[slender nymph]

do you need an entire DI framework?

[boreal tangle]

Say I had 14 days to create a game. would it be worth to learn it. I dont know if I need on ever not seen Ive never used one

[slender nymph]

don't just go adding a giant complex framework to your project if you cannot currently see why you would need such a thing

[swift crag]

I have never touched Zenject and I've never really felt the burning desire for it

[boreal tangle]

ok i wont use it

[swift crag]

make your game.

[cosmic dagger]

Two weeks? Forget Zenject even exists. Just drag and drop . . .

[boreal tangle]

ok

[nimble apex]

can i modify gameobject hierachy under certain gameobject

like this

A
obj1
obj2
obj3

and then make it like this

A
obj2
obj1
obj3

[teal viper]

In code you mean?

[nimble apex]

why? doing it for UIs

yes

[teal viper]

Sure, you can set the sibling index(was it) of a transform.

Look at the Transform docs. It's responsible for placement in the hierarchy.

[nimble apex]

so my team has implemented a very bad UI design , which is common in every dev team in my city

we basically make a parent UI canvas , and then put every single UI we need under it, and we not even doing any sorting layers to any UI

[gaunt ice]

no hierarchy structure?

i mean some sort of subtree or just a list under canvas

[nimble apex]

it has, its just all UI are put under same big canvas u know

[nimble apex]

the way my team call the UI is , call A => call B => call C... so UI will keep stacking

my task now, is to put a panel mask on the top UI, the most "surface one"

so , in order for me to do that, without sorting layers, and a script to store all UIs called, i will need to find every UI i need , and then put the mask under it

[teal viper]

It's not that bad.

[teal viper]

This sounds fine.

[nimble apex]

this is not bad

way better than previous team

aight lemme try it

[nimble apex]

but u cant do sorting layers as the whole UI is almost finished, and they all rely on current structure and without sorting layers

u need to add another canvas on those sub UIs under the canvas right? in order to use sorting layers

[teal viper]

Yeah, I guess so. Though, you don't have to use sorting layers.

Or you could probably add canvases without it affecting stuff.

[nimble apex]

not necessary, but it will be better to have i guess

[signal trail]

Hey Guys, if I want to make a player do an animation when taking damage, Is it better to do things:

A) from the damage script(Enemy Script that handles collision damage) and set a flag on the PlayerController to deal with animation changes
B) Somehow do this directly on PlayerController
C) Other way

[slender nymph]

make the enemy script tell the Player that it is dealing damage. then the player will do whatever it needs to in reaction to that. don't make your enemy control your player

[signal trail]

So A, idk if I worded it right but thats basically what I first had in mind

How would you handle this in your player script? As of now Im just thinking of a variable that when true, triggers the animation in the animator, but Im curious if theres a better way

[slender nymph]

well it sounds like with A you are making your Enemy object tell the player that it should animate. but that shouldn't be the case. the Enemy should only care about dealing damage. So create a method on the player that receives damage and have the enemy call that method. Then the player can do whatever it needs to from that method

[signal trail]

Yeah, I worded that weird, the enemy collision script just triggers a TakeDamage(value) right now

[slender nymph]

that's really all the enemy should be doing. so then your TakeDamage method can notify your animator (or some other component on your player that controls your animator if that's how you have it set up) that it needs to do the damage animation

[queen adder]

Can anyone help me with being able to zoom with the mouse in my camcontroller?

[dense willow]

I just got here and read a bit of the read me, but I'm still confused on if we post questions here or if there is another channel

[slender nymph]

if it is coding related, here is fine. otherwise #🔎┃find-a-channel

[slender nymph]

https://dontasktoask.com

[signal trail]

Right now I actually have all my health stuff in a separate script from the player. IDK if this is good practice or not. So I dont know if I should just merge that to my player controller or just have the TakeDamage call a method in Player controller

[slender nymph]

the latter probably

[signal trail]

Thanks a lot boxfriend

[slender nymph]

or slap an event on it that the player controller subscribes to

[dense willow]

I think this should be something along the lines of finding the camera game object and implementing a scroll wheel system to give off a float variable. Then you'd set it equal to the variable you made the camera size

[dense willow]

Damn

[queen adder]

Sorry, you're right. I already have some initial code, I don't know if it's right but I want to change it in a way that actually works haha

Anyone ever inherited contentsizefitter to implement their weird thingies?

where the 'if' statement starts is where the scrollwheel is meant to work.

[slender nymph]

you probably want to change the transform.localPosition rather than the transform.position
but also i recommend swapping to cinemachine for camera controls. and also not making your camera a child of the player

[queen adder]

ok, thank you!

[vast ivy]

Anyone know why I might be getting the wrong mouse position when I try to drag? Like to drag the first slot I have to be like 100pixels to the left of it to pick it up?

    public void OnDrag(PointerEventData eventData)
    {
        // Convert event position to canvas space
        Vector2 position;
        RectTransformUtility.ScreenPointToLocalPointInRectangle(
            canvas.transform as RectTransform, 
            eventData.position,

[edgy fox]

3rd image is from a second class, if I have a debug.log in the first class and I click on a button placeMode = [the correct mode] and CurrentMode when called from that class outputs [the correct mode] but when I call CurrentMode from another class and I debug.log(mode it outputs "none"

[gaunt ice]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/enum
no quite related to your problem but i think you need it

[edgy fox]

I know what enums are how does that relate to static classes?

[gaunt ice]

you can put enum where ever you like

[edgy fox]

so just make placeMode an enum and it works you say?

[gaunt ice]

yes, since you wont mistype room to Room (or vice verse)

[slender nymph]

simply changing to an enum instead of a string won't fix the issue you've described, but it is still a good idea
your issue is also likely due to the order you do things in or other objects changing the value of your static variable. since anything can access it and change it at any time, you need to examine all locations that are accessing it. you also need to make sure you are assigning to it before you try logging it

[edgy fox]

yeah just enumified it, this is the only location that accessed it

and it is only modified in the SelectPlacement function

[slender nymph]

if you are certain that the two locations you have shown that access and modify that variable are the only locations that do so, then the issue is the order your code is running

[gaunt ice]

btw having public static is not good idea as boxfriend said since everything can change it

[edgy fox]

what should I do to make it so only that function can set it but any other function can read it's value

[slender nymph]

you probably want the variable to be private

[gaunt ice]

i think control accessibility down to method level is impossible in c#

so be carefully

[edgy fox]

true but then other classes can not read it

[slender nymph]

you're exposing it through the method that is declared directly below it. read it from that

[gaunt ice]

https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/properties

[summer stump]

If you want something public, make it returnable by a method, or at least make it a private set property

[gaunt ice]

if you want other class can read but not wirte it

[edgy fox]

It turns out it wasn't a code issue

I hadn't pressed the button when testing to change the mode

it was a failure of UI all along

I really should add some visual cue that the button is/isn't pressed

alrighy I'm confused

[slender nymph]

put it inside of a method

[edgy fox]

debug has to be in a method?

[slender nymph]

any expression that is not a member or type declaration has to be

[edgy fox]

in hindsight that seems extremely obvious

I've apparently never tried to use a debug statement outside of a method

[little garden]

why does OnTriggerEnter only happen when a rigidbody accelerates towards my game object

[slender nymph]

here's how you can troubleshoot OnTriggerEnter: https://unity.huh.how/physics-messages

[little garden]

hmm https://docs.unity3d.com/ScriptReference/Physics.ContactEvent.html

what would be the best way to detect if my player touches another game object?

for example, like the crash nitro boxes that instantly kill you when you touch them

[slender nymph]

well the easiest would be OnTriggerEnter or OnCollisionEnter or if you are using a CharacterController then OnCharacterColliderHit or whatever its special collision message is

[little garden]

that only works when
the player explicitly moves towards the object (character collider hit)
or
the object explicitly moves towards the player (trigger/collision enter)
right?

[slender nymph]

what?

if you are referring to the CharacterController's collision message, then yes. that only occurs when the CC performs a Move. the other two do not rely on that

[little garden]

seems like we would need to use both

OnTriggerEnter to detect an object pushing against us
OnControllerColliderHit to detect us pushing against an object (standing on top counts due to gravity i assume)

but im not sure how to detect contact with an object that is not pushing against us nor that we are not pushing against

[slender nymph]

well trigger colliders, which are required for OnTriggerEnter do not physically collide so there is no "pushing against us" there. and you would use that or OnTriggerStay to detect overlaps with trigger colliders.
otherwise colliders that are moving that are not triggers will need their own rigidbodies to produce OnCollisionEnter messages, which will be sent to the CharacterController. the CC just doesn't produce OnCollsion messages on its own

[little garden]

yea

what if both objects have a rigidbody

eg, detect a game object resting against another game object

[slender nymph]

charactercontroller and rigidbody do not mix

but what you've described would be covered by OnCollisionStay. you should consider reading the documentation, you'd figure this stuff out easier

[little garden]

they do if we use a kinematic rigidbody that does not use gravity

[slender nymph]

and yet you still don't need a rigidbody on a CharacterController. as long as the other object has a rigidbody it will send an OnCollision message to the CC

[little garden]

hmm it doesnt seem to trigger OnCollisionEnter

[slender nymph]

show both objects

[slender nymph]

https://unity.huh.how/physics-messages

naturally a trigger collider does not produce a collision message because as we've established they don't collide

but also two kinematic bodies coming in contact with each other also do not produce a collision message

[little garden]

hmm Collision events are only sent if one of the colliders also has a non-kinematic rigidbody attached

[little garden]

should i just assume unity cannot do this level of precise interaction

[slender nymph]

what "level of precise interaction" are you unable to achieve?
if collision messages aren't working for you because you refuse to set up your objects in a way that would allow them to work (you should really just be using OnTriggerEnter/Stay at this point considering you want to use kinematic rigidbodies anyway) then just use physics queries and check it manually

[little garden]

this

[slender nymph]

great! now read the rest of my message

[little garden]

would i do var col = Physics.CheckCapsule(_controller.height, _controller.height + _controller.radius + _controller.radius, _controller.radius);

[delicate pewter]

Basic question: If I instantiate a GameObject in runtime and that prefab has a script attached to it. How can I access that script?

[slender nymph]

instead of using a GameObject reference for the prefab variable, refer to the component directly. then Instantiate will return a reference to the instantiated instance of that component

[languid spire]

GetComponent on the instantiated GameObject

[delicate pewter]

"go.GetComponent<Agent>().layerGoal = goalLayer[i];"

Like this? Didn't work, says it can't find layerGoal, but its just a basic public int in Agent.cs

go is the instantiated object

[slender nymph]

show the Agent class and share the actual error message

[delicate pewter]

Its as basic as it gets

public class Agent : MonoBehaviour
{
    // Start is called before the first frame update
    private int layerGoal;

    void Start()
    {
        
    }

    public void setLayerGoal(int t){
        layerGoal = t;
    }

    // Update is called once per frame
    void Update()
    {
        
    }
    private void OnTriggerEnter(Collider other)
    {
        if (other.gameObject.layer == layerGoal){

        }
    }
}

I just changed it to try and use a function to set it instead and change the variable to private

Still same issue

[slender nymph]

now show the line of code producing the error

[delicate pewter]

                GameObject go = GameObject.Instantiate(prefab, spawnPosition, Quaternion.identity) as GameObject;
                go.GetComponent<Agent>().setLayerGoal = goalLayer[i];

[slender nymph]

there you go. setLayerGoal is a method not a variable

also make sure that your !IDE is configured to help prevent these basic syntax errors

[eternal falcon]

💡 IDE Configuration

If your IDE is not autocompleting code
or underlining errors, please configure it.

Select one:

• Visual Studio (Installed via Unity Hub)

[neat bay]

Does anybody know how I might be able to the the rate of change at a point of an animation curve?

[delicate pewter]

i mean like I said above I did try as a variable first, by directly accessing layerGoal (and it was public then)

This was just a change to try and use a method instead to see if it would work

Same issue

                GameObject go = GameObject.Instantiate(prefab, spawnPosition, Quaternion.identity) as GameObject;
                go.GetComponent<Agent>().setLayerGoal(goalLayer[i]);

[slender nymph]

you're probably using the wrong Agent type then

hover over the type Agent on that line and make sure it shows the correct type

[delicate pewter]

Ah.. the name of the prefab is also Agent

sorry

[slender nymph]

that's irrelevant. prefab names are not types

[delicate pewter]

I mean it works now, changed the scriptname to AgentController

[slender nymph]

then you were using the wrong agent type

[delicate pewter]

Strange, oh well it works, ty

[little garden]

void Update() {
    if (cached_character_controller != null && Physics.CheckCapsule(cached_character_controller.center, cached_character_controller.center, cached_character_controller.radius)) {
        if (!ragdoll_was_forced && canRagdoll && !in_ragdoll) {
            ragdoll_ms_remaining = ragdoll_duration_ms;
            turn_ragdoll_on();
        }

would this do?

oof i instantly ragdoll

[slender nymph]

use a layermask for your CheckCapsule

otherwise it's likely going to find its own collider

still though, i don't see why you don't just use OnTriggerEnter or OnTriggerStay if all you care about is coming in contact with another collider

[little garden]

how tf is a bool considered a and returns detailed information on what was hit.

[slender nymph]

where are you seeing that at

[little garden]

OverlapCapsule seems to be better

[little garden]

https://docs.unity3d.com/ScriptReference/Physics.CapsuleCast.html

Returns

bool True when the capsule sweep intersects any collider, otherwise false.

Description

Casts a capsule against all colliders in the Scene and returns detailed information on what was hit.

[slender nymph]

that's not even the method you are using

and anyway, it populates an out parameter of type RaycastHit for that info

[little garden]

would OverlapCapsule be less expensive than CapsuleCast

[slender nymph]

you can use the profiler if you have concerns about performance

but they aren't really substitutes for one another. one checks if anything is within the capsule's area. the other casts the capsule in a direction. if you do not need to move the capsule for the query, then you do not need capsulecast and can just use overlapcapsule. if you do not need any of the info about what was hit then you can go back to using checkcapsule. no matter which of these you use though you will have to use a layermask

[little garden]

imma assume an overlap check is less computational than a raycast

[timber tide]

CapsuleCast has a direction

[little garden]

oof

var cols = Physics.OverlapCapsule(cached_character_controller.center, cached_character_controller.center, cached_character_controller.radius);
foreach(Collider cs in cols) {
    if (cs.gameObject == cached_character_controller.gameObject) {
        continue;
    }
    bool collider_is_ragdoll = false;
    foreach(Collider c in ragdoll_colliders) {
        if (c.gameObject == cs.gameObject) {
            collider_is_ragdoll = true;
            break;
        }
    }
    if (!collider_is_ragdoll) {
        if (!ragdoll_was_forced && canRagdoll && !in_ragdoll) {
            Debug.Log("overlap: " + cs.gameObject);
            Ragdoll(cs);
        }
    }
}

this doesnt trigger at all x.x

[timber tide]

start debugging

[little garden]

i already know its cus every collider returned is one that is the pleyer itself or inside the player

[timber tide]

good thing though is you don't have to deal with trigger method bs this way

[little garden]

otherwise it should have ragdolled

[slender nymph]

Use a layermask

[little garden]

all layers are Default

[slender nymph]

So change them on either the player or whatever type of object you are trying to detect

[queen adder]

can you guys help me with my issue #archived-code-general if you may

[slender nymph]

By avoiding a layermask and swapping to overlap capsule from CheckCapsule you've started creating way more garbage (especially since you aren't using a nonalloc version)

[slender nymph]

Don't crosspost

[queen adder]

ok

[little garden]

oof error CS1061: 'Collider[]' does not contain a definition for 'toList' and no accessible extension method 'toList' accepting a first argument of type 'Collider[]' could be found (are you missing a using directive or an assembly reference?)

var cols = Physics.OverlapCapsule(cached_character_controller.center, cached_character_controller.center, cached_character_controller.radius);

frame_colliders = cols.toList();

frame_colliders_game_objects = frame_colliders.ConvertAll(new Converter<Collider, GameObject>(c -> c.gameObject));

[slender nymph]

Spell it right

[little garden]

'Collider[]' does not contain a definition for 'ToList' -_-

[slender nymph]

Now use the quick actions in your configured !IDE to add the relevant using directive

[eternal falcon]

💡 IDE Configuration

If your IDE is not autocompleting code
or underlining errors, please configure it.

Select one:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)
• VS Code
• JetBrains Rider
• Other/None

[little garden]

enables the C# extension and gets this -_-

[slender nymph]

Well having a configured IDE is required to get help here so if you don't want to deal with whatever vs code is doing you can switch to a real IDE 🤷‍♂️

[nimble apex]

if you have a configured IDE u will know whats wrong

btw, tolist is a linq function

[timber tide]

how long have you been here that you're posting pics from your phone

[nimble apex]

lol im at work

i cant download discord on my working pc

i dont use laptop, so either phone or working pc in my workplace

[little garden]

shouldnt this be at least detecting ANY colliders?

Collider[] cols = Physics.OverlapCapsule(capsule_center, capsule_center, capsule_radius);

this should detect at least one collider, right?

or would start == end yield a 0 distance overlap check regardless of the radius and thus optimize for

if (distance == 0)
    return empty;

maybe Collider[] cols = Physics.OverlapCapsule(transform.position, transform.position + new Vector3(0, cached_character_controller.height, 0), cached_character_controller.radius);

welp it detects the ground

but doesnt seem to detect the cube unless we actually stand on top of it

welp imma just ignore for now

its good enough, doesnt have to be perfect

[little garden]

how do i get my character to move with my ragdoll instead of freezing in place until it respawns

eg

https://imgur.com/a/8N2ka3p

additionally how do i get a timer to be timescale dependent?

if (old_fps != 60) {
    old_fps = 60;
    ms_per_frame = (int) (1000.0f / 60);
}

if (ragdoll_ms_remaining >= ms_per_frame) {
    ragdoll_ms_remaining -= ms_per_frame;
} else {
    ragdoll_ms_remaining = 0;
}

if (ragdoll_ms_remaining == 0) {
    turn_ragdoll_off();
}

[gaunt ice]

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

i finally found the place that states time.deltatime is affected by timescale

read the "Time Scale" section

[little garden]

like, i would do 1000.0f / 60 / cached_third_person_controller.world_current_scale right?

[gaunt ice]

where is the 60 comes from?

[little garden]

or rather

(1000.0f / 60 / cached_third_person_controller.world_current_scale) * cached_third_person_controller.player_current_scale

to also account for the player time scale in relation to the world scale ?

60 is the assumed target fps

as i currently use targetFrameRate for simulating heavy load

[gaunt ice]

then how you know your machine is actually running your game on 60fps?
btw get the deltatime first then further manipulate it

[gilded pumice]

can I invoke repeating in start with a delay like a coroutine?

or does invoke repeating always call the method every single second with nothing you can do about it?

[little garden]

i use 60 as an assumed target fps, later this would be changed to a game option to toggle between different target frame rates

not sure tho

since targetFrameRate affects how often Update is called and how much render time we get

(eg, 120 fps on a 120 hz monitor)

[gaunt ice]

as i said what if your machine not running your game in your targeted framerate...

eg if the cpu is busy

[little garden]

i guess i should rename it to

int target_FPS; // affects render + timers

int simulated_target_FPS; // affects render only

[gilded pumice]

is there a way to check a compare tag but only every so often?

[novel shoal]

what’s the input.getaxis axis for the keys A,D and W,S?

[golden otter]

The keys relative to the axis are defined in the Input settings which you can edit in the Project Settings -> Input Manager

[golden otter]

by default the axises for the movement are Horizontal (A, D) and Vertical (W, S)

[novel shoal]

aren’t the arrow keys?

[golden otter]

they also are arrow keys

You can add alternative buttons

[novel shoal]

ok ty

https://hatebin.com/mibhdmhdab
this is giving the player a constant speed towards the sky even when spacebar is not pressed

[languid spire]

of course it is, your code makes no sense

what do you think this

        if (Input.GetKeyUp(KeyCode.Space))
        {
            jumpForce = 10f;
            jumpForce = 0f;
        }

does?

[novel shoal]

it adds a force only once

[languid spire]

no it does not

[novel shoal]

bc otherwise it would give a constant speed on the Y

[novel shoal]

do i need to put the second jumpforce thing outside of the if condition?

[dire torrent]

youre assigning it a value of 10f and then setting it to 0f on the same frame so at the end its the same as just doing jumpForce = 0f;

[languid spire]

it sets a variable to 10 then immediately back to 0, nothing more

[novel shoal]

so i need to set it to 0 at the start of the update method?

[languid spire]

how would that help?

[novel shoal]

this way it will add a 10f force to the rigidbody in that frame, and the next will have an 0f force

[languid spire]

you are not even adding force you are just setting velocity

[dire torrent]

you need to "apply the force" when the key is pressed instead of applying it anyway

[novel shoal]

velocity is a force

[languid spire]

not in this context it is not

[novel shoal]

i just modify it if the key is pressed

[novel shoal]

velocity is a vector just as much as the acceleration

[novel shoal]

can't i modify the velocity if the key is pressed?

[dire torrent]

yes thats what you need to do but currently you're modifying the velocity regardless of if the key is pressed or not

[novel shoal]

i know i can just use rb.addforce but i wanted to try other things

[dire torrent]

you dont need to use rb.addforce if you're going for a certain type of movement

[languid spire]

velocity is the result of force not a force in itself

[novel shoal]

but it adds 10f only if the key is pressed, i don't get it

[dire torrent]

Rigidbody.velocity = new Vector3(horizontalInput, jumpForce, 0);

you're constantly applying the jumpForce here
what would be better is to only apply the jumpForce when the key is pressed

[novel shoal]

but it's set to be 0f at the start of the script

[golden otter]

could do += instead of =

[dire torrent]

yea and it remains at 0 anyway because you set it to 10f and 0f on the same frame

[little garden]

why does 16.66667f / 0.999999f result in zero ?

[warm fog]

can someone help make 2d top down car which player can handle like in old GTA games
i am making a open world survival 2d topdown game in unity 2d
can someone help

[novel shoal]

ok

[dire torrent]

a better way would be to ```cs
Rigidbody.velocity = new Vector3(horizontalInput, 0, 0);
if (space)
{
Rigidbody.velocity += new Vector3(0, jumpForce, 0);
}

[novel shoal]

but then how do i set it back to 0?

[dire torrent]

dont need to
just keep it at 10f

whenever space is pressed, it should set velocity.y to 10f for 1 frame and then let physics do its thing

[novel shoal]

but this way the speed on the Yaxis remains 10 after the key is pressed

[dire torrent]

physics should reduce the speed automatically unless you have gravity disabled

[novel shoal]

i don't get it but ok

ty

[dire torrent]

oh actually there's gonna be a small issue lol

it's gonna reset velocity.y to 0 the next frame so its gonna be buggy. The way to fix it would be to not change the velocity.y at all when space is not pressed```cs
Rigidbody.velocity = new Vector3(horizontalInput, Rigidbody.velocity.y, 0);
if (Input.GetKeyUp(KeyCode.Space))
{
Rigidbody.velocity += new Vector3(0, jumpForce, 0);
}

[novel shoal]

okk ty

https://hatebin.com/wdonduqods
is this fine then?

[dire torrent]

is this a 3D game btw?
wondering why z velocity is always 0

[novel shoal]

2.5D

[dire torrent]

oh i see

[novel shoal]

but it's my first game

[dire torrent]

yea that code should be fine

[novel shoal]

kind of a copy of another platform game

i hadn't other ideas about any other kind of game

oh hold on

i need to multiply the horizontalinput for the value of the force i want to add for time.deltatime

right?

[dire torrent]

yea multiplying horizontalInput by time.deltatime is better since it should make the movement in your game not be dependant on frame rate
actually it shouldnt matter if you use time.deltatime on it or not since you're setting it to a constant velocity

[little garden]

oof i was forgetting to set cached_third_person_controller to an instance

[novel shoal]

https://hatebin.com/wtwpepkisj
it's not working for the horizontalInput

[dire torrent]

remove Time.deltaTime, and you can make the 100 into a variable called speed and modify it in inspector to see what speed suits your liking

[novel shoal]

okk

tried, now it works, thanks @dire torrent

[wicked blaze]

I dont really know how to fix this issues and it has always happens to me before but when i try to add an new feature all the other ones stop working and only the new one does, here is the code:

[novel shoal]

Cameraposition = GameObject.Find("Main Camera").GetComponent<Transform>().position;
is this a good way to make the camera follow the player? instead of using another script, just finding it and using its transform?

[wicked blaze]

currently only the crawling works but the crouching and sprint dont

[dire torrent]

1. what is this script on?
2. Dont use Find methods. They're unnecessarily expensive and very easy to replace.
3. you can store a reference to the camera by making it visible in the unity inspector and assign it by dragging the camera onto the field in inspector.

[novel shoal]

1 it is on the player script
2 i did bc the learn.unity tutorial used it a lot
3 so i need to use public Camera mainCamera?

[dire torrent]

the flow of your code is off. look at how the control goes. go through it line by line
this is how its working rn
if shift is pressed
you set the speed to 18f
then if leftcontrol is not pressed
you set speed back to 12f
then if C is not pressed
you set sped to 12f

so in the end the only thing affecting your speed is whether you are holding down C or not.

[dire torrent]

it is best to control the camera by putting a script on the camera itself. Something like CameraController.
its a good way to structure your code so you know that only the script on the camera is affecting the camera. not other scripts.

[wicked blaze]

hm, thanks for explaining but i dont really understand how to fix it

[novel shoal]

okk

[dire torrent]

do you understand why it's doing what it's doing though?

[novel shoal]

but then i still need to find the player gameobject to attach the camera to it

[dire torrent]

yea you would make a reference to it by using something like public Transform playerPosition

[wicked blaze]

yeah, but that problem has happend sooo many time and i never really knew how to fix it

[dire torrent]

you need to use if-elseif-else structure for what you're trying to do

[novel shoal]

https://hatebin.com/optaqwqqdf
like this?

[dire torrent]

i did bc the learn.unity tutorial used it a lot
also forgot to reply about this, Find methods are a big beginner bait. It sounds really easy to just get the object you want by its name but there's lots of issues to this. What if you changed the name of the object at some point, you would have to go everywhere in your code where you referenced it by name and replace it. And find methods are very expensive too... If you have a whole bunch of objects in your scene, its gonna take longer for the Find method to get the object which is gonna make your game slower the bigger it gets.

[novel shoal]

so using a reference is just both easier and less expensive, gotcha

[dire torrent]

this script is on the camera?

[novel shoal]

yup

[dire torrent]

so you're assigning playerTransform the value of gameObject.GetComponent<Transform>(). So it assigns the transform of the camera itself

[distant robin]

hi can someone tell me why the planes gameobject on my ""tree"" have such a weird behaviour?

[dire torrent]

just assign it through the inspector, and remove the line in Start

[novel shoal]

i assigned the player gameobject in the inspector

and with that code it works

no, wait it does not

[dire torrent]

yea it shouldnt because in Start you assign playerTransform back to the camera's transform itself

[novel shoal]

ok, i used playerTransform.GameObject.GetComponent<Transform>(); and it works

[dire torrent]

why though if you're already assigning it through inspector lol

playerTransform already has the value through the inspector. Assigning it again in Start wont do anything except maybe extra redundant calls

[novel shoal]

oh ok

transform.position = playerTransform.position + cameraOffset;
so i need just this line, right?

[dire torrent]

yes

[novel shoal]

ty dude for being patient

also, if something is private, does it mean it's less expensive?

[dire torrent]

no but its better to make things private that arent being referenced from another script/class
good thing you ask because if your only purpose to make something public is to expose it to unity's inspector, you can use [SerializeField] instead.
so something like ```cs
[SerializeField] private Transform playerTransform;

[novel shoal]

what's "serializefield"?

but if the only purpose to make something public is to show it in the inspector, what's the point of making something show while making it private

[wicked blaze]

well, i dont realy know how to do it with the if-elseif-else

because its confusing
