wait

actually it wont what if user needs 0

[wintry quarry]

not sure I'm following this part

[earnest wind]

i think i need sleep, its almost 2 am xD

will come back tommorow to this mess

[earnest wind]

basically

if its 0, it doesnt serialize

even if its in list

so i get lists like this

because alpha is 1 by default

but a float by default is 0

i dont know how to override the alpha to 1 inside the list itself

[wintry quarry]

I'm imagining basically (psuedocode):

serialize() {
  for (i from 0 to defaultarray.length) {
    if (myData[i] != defaultArray[i]) {
      writeOverrride(i, myData[i]);
    }
  }
}

deserialize() {
  deserializedArray = defaultArray;
  for (override in overrides) {
    deserializedArray[override.index] = override.value;
   }
}```

[earnest wind]

and we could have some lists that are like this

yeah my brain isnt braining right now

im looking at this wall of text and i dont understand how i could make this

i understand how it would work

but dont know how to make the serialize part in the newsoft json

im not trying to make my own serializer right now

[wintry quarry]

Like I said you make a custom JsonConverter for your type:
http://newtonsoft.com/json/help/html/CustomJsonConverterGeneric.htm

[earnest wind]

ah, i understand now

[wintry quarry]

readjson == deserialize
writejson == serialize

I do wish their example was a little more in depth

[earnest wind]

yeah its just one example lol, but still i understand, will implement tommorow, thanks

Do ya'll know why my dash code isnt working, Ive looked through it and for the life of me I can'tfigure out whats wrong

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

public class PlayerMovement : MonoBehaviour
{

    public float moveSpeed;
    public Rigidbody2D rb;
    private Vector2 moveDir;

    private float activeSpeed;
    public float dashSpeed;

    public float dashLength = 0.5f, dashCooldown = 1f;

    private float dashCounter;
    private float dashCoolCounter;
    // Update is called once per frame
    private void Start()
    {
        activeSpeed = moveSpeed;
    }
    void Update()
    {
        ProcessInputs();
    }
    private void FixedUpdate()
    {
        Move();
    }
    void ProcessInputs()
    {
        float moveX = Input.GetAxisRaw("Horizontal");
        float moveY = Input.GetAxisRaw("Vertical");
        moveDir = new Vector2(moveX, moveY).normalized;

        if (Input.GetButtonDown("Dash"))
        {
            print("success");
            if (dashCoolCounter <= 0 && dashCounter <= 0)
            {
                activeSpeed = dashSpeed;
                dashCounter = dashLength;
            }
        }
        if (dashCounter > 0)
        {
            dashCounter -= Time.deltaTime;

            if (dashCoolCounter <= 0)
            {
                activeSpeed = moveSpeed;
                dashCoolCounter = dashCooldown;
            }
        }
        if (dashCoolCounter > 0)
        {
            dashCoolCounter -= Time.deltaTime;
        }
    }
        void Move()
        {
            rb.velocity = new Vector2(moveDir.x * activeSpeed, moveDir.y * activeSpeed);
        }
    
}

[rich adder]

put logs

that print("success"); is kinda useless

you need more and preferably print actual values

[kindred path]

Yeah I was just checking that my Input manager was working cause I didnt know

[kindred path]

I was using the wrong variable 😐

[unkempt kettle]

Hey, I got a question about scriptable objects

Context
I'm making a magic system in my game that you can only have one active spell in your spellbook and need to change it frequently. I though about making it with scriptable objects, but I also want them to level up in certain points of the game (altering the scriptable object).

Question
How can I write values into my scriptable objects?
In this case, I want to be able to change my Spell Level from 1 -> 2 and vice-versa (Ex: When getting an upgrade / Loading a save file)

[rough granite]

How can I write values into my scriptable objects?
the same as you would any other script

also whoops misclicked

[unkempt kettle]

I thought scriptable objects worked like separate instances from the actual script, how exactly can I reference it?

[sour fulcrum]

There's two routes you can go, with the first being more ideal so i'll elaborate on that more than the other

1. You basically make a "live" version of your spell class and have a sibling-esque relationship with your scriptableobjects. Here you would use your scriptableobject to give the "live" version of the class it's default values, then modify that instance of the class how you need

2. Runtime creation of scriptableobjects

[unkempt kettle]

I'll look into it, thank you very much 🫂

[rough granite]

no each instance is made in your project folder you can reference them after by make the reference in code serialized
[SerializeField] ScriptableObject ScriptableObject;

[unkempt kettle]

oooo, ok I got it, thank you

[sour fulcrum]

Though as you might be already cautious about direct changes to scriptableobject assets at runtime will not reset when you exit play mode

[rough granite]

yeah quite annoying especially since they do reset if changed outside of a unity runtime (meaning if the game was build they don't save after each load)

[sour fulcrum]

I mean yeah theres no way they could do that

thats just how assets work

[rough granite]

they could just reset them in unity after though

at least have it consistent you know

[sour fulcrum]

that would be inconsistent with how assets are treated in unity tho

[rough granite]

i mean i guess :/

[weak roost]

Hi there,
how can I ensure that monobehavior GUIs can register for events from controllers that are plain C# classes without being null? Calling a new Controller in awake and then registering for the event in onenable/ondisable always returns a null pointer because the instance is created too late.

How do you solve such a general problem?

[teal viper]

Awake is called before OnEnable, so it shouldn't be null pointer.
https://docs.unity3d.com/6000.0/Documentation/Manual/execution-order.html

I suggest debugging it thoroughly or providing more details(code, errors, setup screenshots, etc...)

[hot wadi]

About DontDestroyObject scripts, do I have to assign scene-specific references during runtime?

[teal viper]

Not quite clear what you mean.

[naive pawn]

do you mean DontDestroyOnLoad

[hot wadi]

DontDestroyOnLoad objects persists between scenes, and there are objects that only exist in certain scenes.
I know can manually find each of them in the script, but it feels tedious and possibly slow the game if it's large enough
So I'm looking for alternative if there is one.

[teal viper]

1. Finding is not always bad. If it gets bad, then perhaps there's a more basic issue:persisting too many separate objects between scenes.
2. There are many other ways to get a reference to something, other than using the find methods.

how can i add normal mapping for my textures?

seems easy to but i dont know

[worthy veldt]

i just found out i can't inherit from plain class, so currently my banana can technically contains items like my pouch because i just jammed it all in Item class. no problem so far, but what is the correct way, make multiple classes ?

[teal viper]

Why can't you inherit from a plain class..? 🤔

[worthy veldt]

there is an error and from google ai it said

In Unity, you can inherit from a custom Item class, but issues can arise with serialization and editor functionality if Item is a plain C# class and not derived from MonoBehaviour or ScriptableObject.

[teal viper]

It doesn't seem like you're doing any light calculations at all. There's no point in a normal map, as it's usually used as part of the light calculation.

[lethal meadow]

do i not use the unity lighting?

[teal viper]

You can, but I don't see anything related to it in your shader.

[lethal meadow]

how do i use it then

or would it be better to make my own lighting system

i made an engine a while ago and the lighting was definitely very poor

im not that good with shaders

[teal viper]

Well, this doesn't really say anything specific. Plain classes can be serialized if they are part of a MonoBehaviour/So or if you have a custom editor for them.

[teal viper]

Definitely better to use what Unity provides. You'll need to research how to use unity shader includes and call the lighting calculation function from your shader.

[sour fulcrum]

(This is why you don’t use ai)

[teal viper]

Honestly, I'd use shader graph instead of writing a custom shader.

[lethal meadow]

but ive got structs and looping going on

[teal viper]

Because it's gonna be a pain in the ass, especially if you don't have experience.

[lethal meadow]

and i dont think you can do that

i'd definitely use a shader graph though

[teal viper]

You can with a custom function/hlsl node.

But currently I don't see anything that is not implementable in a shader graph by default.

[worthy veldt]

arent plain class not inheriting from anything by definition ?, it did said

"Use [SerializeReference] for polymorphic serialization of plain C# classes. This attribute allows Unity to correctly serialize and deserialize derived types within a collection or field, preserving their specific data. You might also need a custom editor to manage adding different derived types in the Inspector."

but im afraid ill break my stuff with current setup. maybe ill delve into it when im free

[sour fulcrum]

as a statement the text that ai provided in this specific scenario is not wrong

but as an answer to your question its pretty abyssal

base class usage in unity is extremely common and unity supports it explicitly

like anything in unity, things can go wrong if you do it wrong

[teal viper]

Or you can take the unity standard shaders source code and modify them instead. Still gonna be easier than writing from scratch. Or at least use them as a reference.

[sour fulcrum]

and because its not a monobehaviour or scriptableobject, they way you treat them is abit different

[teal viper]

It's hard to say anything specific without knowing your project/setup, but generally inheriting from a plain class is very much an option and is often used in unity.

[worthy veldt]

yea i just test with empty new plain classes inheriting works fine. ill look into my prob

[worthy veldt]

so.. my derived class needs constructor that supports my base class, it has to be written in certain way..

i didnt know the syntax alright

but i already made my container banana, ill refactor and change it later..

If it doesn't work in the editor then it won't work in the build either

the code never saves anything to playerprefs

[alpine temple]

bestTimeL1 = PlayerPrefs.GetFloat("BestTimeL1", bestTimeL1);
PlayerPrefs.Save();
does this not work

[keen dew]

No. You're not telling it what to save and where

SetFloat is for saving floats to playerprefs

bestTimeL1 = quickReload.timerTime;
if (quickReload.timerTime <= bestTimeL1 || bestTimeL1 == 0)

this is also wrong, if you've just set the both variables to equal each other then the condition on the next line where it checks if they're equal will always be true

[rough granite]

No GetFloat finds any past saved data for the key string you'd need to use SetFloat to save to that key string.

[alpine temple]

yep that works thank you very much

[naive pawn]

ask in #🖱️┃input-system and provide some more info. what exactly is going wrong? are you getting errors?

[glad fjord]

Can anyone help me with understanding what the use of ADDING Time.deltaTime is, please?
I understand why we would multiply by it, but why would one add it to make a timer for example? How would that make any sense?

[waxen glacier]

So i've added a RayCast to try and get the angle of a surface so I can modify movement on slopes, but the problem is that i'm getting the angle of the raycast relative to the surface normal instead of the actual incline of the terrain, and I don't know what I should write to get that angle.
https://paste.ofcode.org/daj5pGjCJ427y7r5Djvc9g

As a visual example to make myself clearer, the blue angle is what I get with my current code, the red line is the RayCast and the green line is the ground normal. I want to be able to get the value of the pink angle instead, but I don't know where to start.

[keen dew]

The blue and pink angles are the same

[alpine temple]

im doing stuff like this to save BestTimes for different lvls is there a simpler way to do this?

[naive plank]

How would I go about moving on low poly terrain, still following the mesh but without that bumpy, slow, and getting stuck feeling?

[grand snow]

custom collision mesh thats better?

also split this into sections so you can use occlusion culling

[wintry quarry]

Low hanging fruit here would be to stop hard coding the level names and keys.

Either use the scene name (directly or with a prefix/suffix) as the playerprefs key, or put a component in the scene that gives you the level name and use that.

Then you can stop duplicating the code for each level too. The code duplication is terrible.

[naive pawn]

deltaTime is how much time has elapsed since the last frame
if you want to get how much time has elapsed over multiple frames, you sum each frame's deltaTime

[naive plank]

I've been thinking about that, whats holding me back is, the player model, im using a capsule collider right now and have foot IK "snapping" the feet to the ground, then I would need to layer the ray casts, that would be fine, but I somehow need to adjust the collider hight too otherwise the distance to the ground is too big making the foot float instead

[wintry quarry]

It makes perfect sense to add it if you're adding up how much time has passed, like a timer as you said

[naive plank]

https://gyazo.com/1cb0176e729fbb4288c4032269d64ffa I dont really know how I would combine everything like that

[glad fjord]

humm.. I see. but then how does Unity know I'm talking in seconds and not in frames when I'm building a timer?

[naive pawn]

it doesn't

you do

you decide how to interpret the values

[glad fjord]

here for example, how does Unity know 2 and 0 are seconds? the rest of the code doesn't seem to specify it in any way

[grand snow]

good lord its up to YOU

[alpine temple]

if (quickReload.timerTime <= bestTime || bestTime == 0)
            {
                bestTime = PlayerPrefs.GetFloat(currentSceneName, bestTimeL1);
                if (bestTimeL1 > 0)
                {
                    timeSaved = bestTime - quickReload.timerTime;
                    TimeSaved.text = string.Format("- {0:F2}", timeSaved);
                }
                Invoke("BestTiemDelay", 0f);
            }

somethin like this?

[glad fjord]

but HOW then

[grand snow]

Time.deltaTime is seconds so if you use as is then its all seconds

[glad fjord]

well here we go

[naive pawn]

nothing about it says they're in seconds. if you treat them as seconds, then they're seconds

3 can be 3 seconds, 3 frames, 3 meters, 3 meters per second, etc

it's all up to how it's used

[glad fjord]

so in order to treat them as seconds, I need to add seconds to them?

[grand snow]

Look up the documentation page if you need to know such information
https://docs.unity3d.com/ScriptReference/Time-deltaTime.html

[glad fjord]

I have read this

[naive pawn]

no, if you want them to be seconds, you need to think of them as seconds

[glad fjord]

I understand that it might seem basic to you guys but it is not to me. I don't understand how UNITY can think of them as seconds

[naive pawn]

and use them accordingly
setting or adding a value? make sure it's in seconds
passing it as an argument to something else? make sure that thing expects seconds

[naive pawn]

unity does not

the language just does not have a concept of units

this exists entirely outside the code

[grand snow]

float timerInSeconds = 0f;
void Update()
{
  timerInSeconds += Time.deltaTime;
}

oh look its counting real time in seconds because the source value is the delta for that frame in seconds

[naive pawn]

this is how you treat a variable as seconds

float time;
Debug.Log($"time: {time} seconds");

it's all about how you, the developer, intend it

it does say "seconds" in the code, but that's inside the string. unity and c# don't care about that, that's for your eyes, the developer

[glad fjord]

the guy in the tutorial I'm watching did not specify any number. he simply wrote timer += timer + Time.deltaTime;
AND he said the timer would count 2 SECONDS until it resets
so how does this make any sense?

[naive pawn]

calm down, you're trying to find a link where there isn't one

[glad fjord]

he did write public foat spawnRate = 2 and private float timer = 0 but why would those be counted as seconds then

[naive pawn]

because he said so

that's all it is

[glad fjord]

hahahaha I don't get it

[grand snow]

float timerInSeconds = 0f;
void Update()
{
  timerInSeconds += Time.deltaTime;

  if(timerInSeconds >= 2f)
  {
    DoSpecialThing();
    timerInSeconds = 0f;
  }
}

[naive pawn]

unity is not sentient - it does not think about seconds

[glad fjord]

but then how does it count 2 SECONDS before it resets

[grand snow]

Indeed. Its our logic that makes things happen when we want

[glad fjord]

if he didn't put in any math

[grand snow]

Look at my example

[naive pawn]

Time.deltaTime is just some random number, but unity devs defined it to be seconds
so when you set a variable to that value, it is also in seconds

[alpine temple]

how do you send codes like that

[grand snow]

when you compare it to other values, those are also in seconds (otherwise it wouldn't make sense)

no, it just means it's a float

[grand snow]

its a float literal

[alpine temple]

'''cs
//buh
'''

[grand snow]

the number 2 as a float

[glad fjord]

so this is what I said, it is because it is related to seconds (Time.deltaTime) that it ends up being seconds, right?

[glad fjord]

ok

[quick fractal]

Use `, not '

[alpine temple]

buh

cool thanks

[naive pawn]

yeah
but another layer to that - Time.deltaTime is just in seconds because unity devs decided to have it in seconds

perhaps throw out "seconds" for a bit, you might be thinking too narrowly

[grand snow]

If the game is running at 60fps then Update() is called 60 times a second and Time.deltaTime will be 0.016. 0.016 * 60 is? 1! (nearly)

[glad fjord]

yeah I get that

[grand snow]

Then you should get why we use it to count time passing in this way

[glad fjord]

I just find it odd that simply relating a random number to something counted in seconds automatically makes it count as seconds

but if that's what it is that's fine I get it now

[grand snow]

because your understanding is flawed, the value we are using is the frame DELTA

There is an alternate way to check for passed time that may make more sense to you:

float lastTime = Time.time;

void Update()
{
  if(lastTime + 2f < Time.time)
  {
    DoSpecialThing();
    lastTime = Time.time;
  }
}

this does a thing every 2 seconds

[naive pawn]

Time.deltaTime is just some value, let's say it's 0.1
we could count Time.deltaTime over multiple frames, let's say we've gone through 15 frames so the total would be 1.5

that value, 1.5, doesn't mean anything on it's own. period. there is no inherent property that makes it count seconds

[glad fjord]

what do lastTime and Time.time stand for here?

the last frame and the current one?

[grand snow]

We record the current Time.time value (which keeps track of time in seconds since the game was launched) and keep checking till atleast 2 seconds has passed. When this happens we do a thing and update the last time we did the thing.

This works because each Update() Time.time is different as its being advanced by unity for us

[glad fjord]

but you did say Unity makes this specific thing count as seconds, no?

[naive pawn]

you, as the developer, can interpret that value to have more meaning than just 1.5

we know Time.deltaTime is in seconds, because unity devs said so (and made it count as if it were in seconds, accordingly)
then when we count, because we're summing seconds, we know the result is also in seconds - so now we can apply meaning, that the value of 1.5 in this context means 1.5 seconds

[naive pawn]

yeah i probably shouldve sent these as a single message ^

[glad fjord]

oooooh yeah that just made it way more clear

he just never specificed that Time.deltaTime was counted as seconds tbh that's the key thing

[quick fractal]

-# 🤔

There's a timer example there that explains it

[glad fjord]

but 2 times 0.0something won't make 2 seconds would it now?

[naive pawn]

not sure where you got the "2 times" part from?

[glad fjord]

how does he end up with a 2 seconds timer

[waxen glacier]

I just saw your reply and drew it on paper to check, you're right 😭 i've been torturing myself with this for 3 days now, thanks

[glad fjord]

well this

[naive pawn]

there's no multiplication there

[glad fjord]

hum you're right I messed that up

so timer is equals to timer + Time.deltaTime, but that doesn't equal to 2 seconds tho

[naive pawn]

but that happens a lot of times

timer accumulates the deltaTime

[glad fjord]

tho he did say the timer would be 2 seconds

oh

[wintry quarry]

because Time.deltaTime is in seconds, not frames

[grand snow]

we are going in CIRCLES AAAAAA

Try out the examples and witness them work and deal with it

[naive pawn]

suppose a consistent deltaTime of 0.2 (aka 5 fps)```
frame 0: timer = 0.0
frame 1: timer = 0.0 + 0.2 = 0.2
frame 2: timer = 0.2 + 0.2 = 0.4
frame 3: timer = 0.4 + 0.2 = 0.6
frame 4: timer = 0.6 + 0.2 = 0.8
frame 5: timer = 0.8 + 0.2 = 1.0

[glad fjord]

I think I get it: it ends up being a 2 seconds timer because it says that until timer is at least equal to spawnRate, which is 2, then it will reset.
so spawnRate also ends up being counted as seconds in that situation?

[wintry quarry]

note that the computer doesn't actually "know" anything. it simply performs the commands you give it

[naive pawn]

float lastTime;
void Update() {
  float deltaTime = Time.time - lastTime;
  Debug.Log($"{deltaTime} seconds elapsed");
  lastTime = Time.time;
}
``````cs
float lastPosition;
void Update() {
  float deltaPosition = transform.position.x - lastPosition;
  Debug.Log($"{deltaPosition} meters traveled");
  lastPosition = transform.position.x;
}
```these 2 snippets are equivalent if you just look at the numbers. we can analyze that the first is using seconds and the second is using meters because of what other values it's using - ones that are defined as those units
but sometimes you don't have values that have predefined units, you might specify those units yourself - and that's all in how you decide to treat them, not related to how it's written at all

[glad fjord]

yeah I think I get that

I'm just not fully sure about how it ends up being a 2 seconds timer, in relation to the spawnRate

[naive pawn]

it's counting in time

if the counted time is more than spawnRate, do the thing

[wintry quarry]

spawnRate is just the number 2. It's what you're checking your stopwatch against. "Have 2 seconds passed yet?"
timer is like a stopwatch.

[naive pawn]

Time.deltaTime is in seconds and spawnRate is 2, so it happens to be 2 seconds
nothing about the logic thinks about seconds

[glad fjord]

so spawnRate will be treated as seconds too then?

because it couldn't define that timer is inferior or not to spawnRate otherwise

[naive pawn]

since there's no conversion factor, yeah

[glad fjord]

ok

[naive pawn]

you could have it checking against spawnRate * 60 and then it'd be treating spawnRate as minutes

[glad fjord]

it's all in relation to something then

[naive pawn]

it's usually thought of in the other way though

[grand snow]

[naive pawn]

you decide that spawnRate is in seconds

[glad fjord]

almost there

[naive pawn]

then if you end up comparing spawnRate to a value in minutes, that's just a mistake - it doesn't redefine spawnRate

[glad fjord]

now last thing: I'm getting confused about how "timer = timer + Time.deltaTime;" doesn't end up being 0 = 0 + Time.deltaTime

[naive pawn]

the left side isn't 0

[glad fjord]

since we defined that timer is equal to 0 before

[naive pawn]

= is an assignment

[glad fjord]

yeah I assumed it wasn't but why

oh

[naive pawn]

it's setting the variable timer to be the value timer plus deltaTime

[wintry quarry]

it is 0 + Time.deltaTime on the first frame

[glad fjord]

so how exactly does Unity treat the left timer as something to get value from the right part, instead of treating it as 0?

[wintry quarry]

0 + .015 gives you 0.015

[naive pawn]

it doesn't

this is how c# works

[wintry quarry]

The way = works in C# is that the thing on the left BECOMES the thing on the right

a = 5; makes a be 5

[naive pawn]

= takes the value of the right side and puts it into the variable on the left

[wintry quarry]

it doesn't matter what a was before

[naive pawn]

just like how float timer = 0; was before

if you took the left side as a value that just wouldn't work, since timer didn't exist before that point

[glad fjord]

ooh ok that makes total sense

was missing this info

[wintry quarry]

so this was a.. you didn't understand how = works in programming?

[naive pawn]

that's basic c#, so.. you're definitely in too deep for your level of understanding lol

[balmy vortex]

why does the stuff in void Start() not carry over to the statement in void Update()?

[wintry quarry]

Because when you declare a variable in a method it is local to that method only.
The place where you declare a variable determines the scope of that variable

[naive pawn]

configure your !ide

[glad fjord]

I got it mistaken

[glad fjord]

well now I understood everything!

so thank you guys, it felt like my dad screaming at me for not understanding math all over again but it was worth it

[balmy vortex]

well why does this not work then?

[naive pawn]

@balmy vortex do this first.

[frosty hound]

Because you're making new variables inside of an if statement. Think of the { } as "walls". If you make something inside of it, nothing outside of it will know of its existence.

If you want variables which are accessible throughout your script, put them outside these functions, at the top (but inside your class)

[polar acorn]

To be more precise, when you declare a variable in a scope it is local to that scope only. Praetor was likely not wanting to introduce the concept of scopes to someone who hasn't even configured their IDE and is likely just starting

variables exist until they hit a }

[wintry quarry]

Because I gave you a partial answer and in fact it's any scope that you declare the variable in that it's local to, not just methods.

Using {} defines scopes

Hello everyone. I have a material with shaderGraph shader which just outputs a simple noise. I want to render this material into renderTexture, but it is not working. I created a script which does
Graphics.Blit(null, renderTexture, material);
then I assign this texture to a RawImage to see results. Maybe I need to do something with UVs. How should I do rendering of custom material into square render texture?

[grand snow]

Try normal UV input instead of screen pos.
And go to rendering to ask such questions

            }
        }

why's it just snap directly to the bottom position

ignore the spacing discord messed it up

[ivory bobcat]

What's it supposed to do instead?

[primal trench]

lerp between the current camera position and the new vector 3

[ivory bobcat]

Well, you're not doing proper linear interpolation so I would advise you first to consider that. Otherwise, this likely all happens instantly as it doesn't seem to be yielding control

[polar acorn]

Which it does. In one frame, because loops run to completion before anything else can happen

[primal trench]

oh. how do i fix both those issues?

[ivory bobcat]

Depends.

[polar acorn]

Don't use a while loop and have the timer tick down in Update

[primal trench]

what'd be the better way?

[ivory bobcat]

You should show more !code if you're wanting advice. Otherwise as suggested, process the lerp in Update without the loop

what do you mean by the last part? all i need to to transtiion a position ebtween two points

[ivory bobcat]

Right now, the function will complete the loop before exiting the function.

[hot wadi]

Start is called at the beginning of an object when a new scene is loaded, right?

[grand snow]

called once after a monobehaviour is created and enabled

so that also happens to occur when a new scene opens

[hot wadi]

Oh right, but not really for a singleton

[grand snow]

not relevent, if the component already had Start() called it wont happen again

[hot wadi]

I mean the second part

DontDestroyOnLoad singletons

[grand snow]

Do not confuse the two

[hot wadi]

They run one time only, so the scene loading does not call Start on them

[grand snow]

If you load a new scene, it will create gameobjects and their monobehaviours may then have Start() called because they are newly made

[hot wadi]

I get what u mean

[grand snow]

If you move one of those gameobjects do dont destroy on load, start() will NOT be called on it again

[ivory bobcat]

The objects that have been marked to not be destroyed aren't being created in the new scene so they do not call Start. They had already called Start when they were created.

[hot wadi]

Uhm, I just said that

So there is that

[grand snow]

If you understand then thats good case closed

[obsidian fox]

I m fairly new to Shadergraph and I want to know if its possible to add text on a texture using Shadergraph?

[lunar coral]

hello,I have an issue in my gunsystem script, the player can shoot thru walls and still hit enemies, the WhatIsEnemy layer contains walls obstacles and enemies

if (Physics.Raycast(fpsCam.transform.position, direction, out rayHit, range, whatIsEnemy))
{
if (rayHit.collider.CompareTag("Enemy"))
{
rayHit.collider.GetComponent<Enemy>().TakeDamage(damage);
}
else
{
Instantiate(bulletHoleGraphic, rayHit.point, Quaternion.Euler(0, 180, 0));
}

    }

[ivory bobcat]

Maybe you should check if a wall was hit first?

[grand snow]

That would be quite difficult so don't bother. Use text mesh pro to show text somewhere

[lunar coral]

the RayHit doesn't stop the ray?

I went in holiday for 15 days and it looks like I've forget everything

[ivory bobcat]

Say what? Ray hit would be the object that was hit.

[lunar coral]

yes

[ivory bobcat]

It doesn't have anything to do with stopping a raycast.

[lunar coral]

the ray hits the wall first which is in the layer, so the RayHit basically is the wall

which would stop the ray?

from going further$

no?

[ivory bobcat]

Check if the wall has the same layer mask

[lunar coral]

they do

different layers but they both are referenced to the WhatIsEnemy variable

[polar acorn]

1. !code
2. Show where you define whatIsEnemy
3. Show the inspector of the object you're expecting to block the raycast

[ivory bobcat]

At this point my assumption is that either the enemy object was hit before the wall because it was closer, the wall isn't on a layer to be hit or the layer mask isn't correct.

[lunar coral]

it's not closer, the enemy was like 100 meters behind the wall

[polar acorn]

You cropped the actual relevant bit out of this screenshot

[lunar coral]

🤦‍♂️

IM TOO DUMB, I created the layers, but didnt assign them to the walls and obstacles

[polar acorn]

This is why when someone asks you to check something you actually check it instead of just assuming you did it

[lunar coral]

which is also the reason the hit effects weren't appearing$

[lunar coral]

yes im sorry, I really thought I had assigned them tho,

[polar acorn]

When it'd take like two seconds to check, you should just check.

I have not left the house without my phone and wallet in like ten years but you can bet that I pat my pockets every single time I leave the house before I lock the door

[lunar coral]

yea, I know, thanks for your advice

[umbral bough]

Hey, I was under the impression these 2 were supposed to be the same, with the exception of the first one ignoring the mass of the rb:

_rb.AddRelativeTorque(new(_flipRotation, 0), ForceMode.VelocityChange);
_rb.AddRelativeTorque(new(_flipRotation, 0), ForceMode.Impulse);

However, I noticed that the VelocityChange one messes up the rotation occasionally, it just feels off and is sometimes a mirror of what it should be(I flip in the opposite direction).
Is this a bug or am I misunderstanding how this works?
Please @ me and thanks in advance!

[wintry quarry]

To be precise it ignores the inertia tensor, (which is essentially rotational mass)

Flipping in the opposite direction might just be a result of going too far in one direction or reaching the limits of the maximum rotation rate. It's hard to say without being privy to the exact details here

[umbral bough]

Would be nice if there was a built in way to just ignore the mass tbh, guess I'll just stick to impulse and scale with mass :/

[primal trench]

        public IEnumerator StartSlide()
        {
            if (IsGrounded)
            {
                ElapsedTime = 0;

                while (ElapsedTime < 0.1f)
                {
                    PlayerCamera.transform.localPosition = Vector3.Lerp(PlayerCamera.transform.localPosition, new Vector3(0, -0.346f, 0), ElapsedTime/0.1f);
                    ElapsedTime += Time.deltaTime;
                    yield return null;
                }
            }
        }

        public IEnumerator EndSlide()
        {
            ElapsedTime = 0;
            while (ElapsedTime < 0.1f)
            {
                PlayerCamera.transform.localPosition = Vector3.Lerp(PlayerCamera.transform.localPosition, new Vector3(0, 1.125f, 0), ElapsedTime/0.1f);
                ElapsedTime += Time.deltaTime;
                yield return null;
            }
        }

why does the players' view jitter up and down when the button is pressed quickly?

        void OnSprint(InputValue Value)
        {
            if (Value.isPressed)
            {
                Debug.Log("Test");
                PlayerFPController.StartCoroutine(PlayerFPController.StartSlide());
            }
            else if (!Value.isPressed)
            {
                PlayerFPController.StartCoroutine(PlayerFPController.EndSlide());
            }
        }

this is the input code

it's only when the button is seemingly pressed before the 0.1 second timer ends

the only "fix" i've found is stoppuing all coroutines in the input code, but that seems not the best, stopping the two coroutines individually doesn't work??? they're the only two coroutines.

[keen dew]

Stopping them individually does work but it's very easy to do it incorrectly

[primal trench]

i was just doing (simplifying bc im lzy)
stop coroutine (end slide)
stop coroutine (start slide)
i did this in the input code

for both released and pressed

[keen dew]

You need to show what you actually did for us to tell what was wrong with it

that does work if you do it right

[primal trench]

        {
            if (Value.isPressed)
            {
                PlayerFPController.StopCoroutine(PlayerFPController.EndSlide());
                PlayerFPController.StopCoroutine(PlayerFPController.StartSlide());
                Debug.Log("Test");
                PlayerFPController.StartCoroutine(PlayerFPController.StartSlide());
            }
            else if (!Value.isPressed)
            {
                PlayerFPController.StopCoroutine(PlayerFPController.EndSlide());
                PlayerFPController.StopCoroutine(PlayerFPController.StartSlide());
                PlayerFPController.StartCoroutine(PlayerFPController.EndSlide());
            }
        }

i don't know why this wouln't work

[keen dew]

You have to stop the same coroutine that you started, not a new one. See https://unity.huh.how/coroutines/stopcoroutine

[primal trench]

aren't i alreasdy doing that? sorry if i seem dense

[west garnet]

im making a boss battle and the boss instantiates a few minions
i made an observer pattern for the health, does anyone know how can i make each minion with their own event

[keen dew]

No, every time you call StartSlide or EndSlide it starts a new coroutine

[primal trench]

ohhh, how would i end them correctly then?

[keen dew]

There are instructions in the link I posted

[primal trench]

that works for the coruoutine i start in the if statement, but i'm not starting the other one, how would I do that?

is there a way to get running couroutines?

[keen dew]

I don't quite get what you're asking

[sour fulcrum]

startcoroutine returns the coroutine value

[keen dew]

check if the variable is null before calling stopcoroutine

[primal trench]

        {
            Coroutine EndSlideCoroutine = null;
            Coroutine StartSlideCoroutine = null;

            if (Value.isPressed)
            {
                if (StartSlideCoroutine != null)
                {
                    PlayerFPController.StopCoroutine(StartSlideCoroutine);
                }
                if (EndSlideCoroutine != null)
                {
                    PlayerFPController.StopCoroutine(EndSlideCoroutine);
                }
                StartSlideCoroutine = PlayerFPController.StartCoroutine(PlayerFPController.StartSlide());
            }
            else if (!Value.isPressed)
            {
                if (StartSlideCoroutine != null)
                {
                    PlayerFPController.StopCoroutine(StartSlideCoroutine);
                }
                if (EndSlideCoroutine != null)
                {
                    PlayerFPController.StopCoroutine(EndSlideCoroutine);
                }
                EndSlideCoroutine = PlayerFPController.StartCoroutine(PlayerFPController.EndSlide());
            }
        }```
like this? it still doesn't work

[polar acorn]

Local variables cease to exist when the function ends

[keen dew]

well no because those are local variables that disappear right after the function ends (and even if they didn't they're set to null at the start, removing any coroutine that might be stored there)

[polar acorn]

So you press sprint, you set those Coroutine variables to null

So you are calling StopCoroutine on a null

[keen dew]

make class fields (private Coroutine EndSlideCoroutine;) outside the function

[primal trench]

i made it public and now it works :) thaks

one more think, when going down slopes do character controllers by default increase in speed or do i need to make that?

[keen dew]

Depends how much you want to increase the speed, the simple ones usually go faster in relation to the slope because the vertical velocity stays the same

(but not noticeably)

[hot wadi]

Awake() should be called first time even when an object is inactive, right?

[primal trench]

oh i meant the component

[naive pawn]

if the object starts inactive, it'll be called when the object becomes active for the first time
(if that doesn't answer your question, could you clarify? im not quite sure what you're asking)

[keen dew]

You have to code the movement to that yourself anyway so in that sense you do need to make it

[primal trench]

any advice to where to startt witht hat?

[uneven furnace]

Hi, I bought Harrison Ferrone's book "Learning C# by Developing Games with Unity". Has anyone read it?

If you're looking for a specific recommendation then it's probably too late since you already bought it.

[red igloo]

I have this script where when I press esc the game should pause and the cursor should show and when you un pause it shouldn't show. the pausing works but the cursor doesn't show at all in the build version nor does it really work in the editor am I doing something wrong?

https://paste.ofcode.org/Ft94nrnMyycBecH8XpCCF

[rough granite]

Is there anywere else in your code that the cursor state is being changed?

[red igloo]

yes in my fps controller I have this

[rough granite]

and when is this called?

[red igloo]

I'm calling it in update

should I just reference the lockCursor bool from my fpsController?

[rough granite]

Why not just change the bool lockCursor in the fps controller in the MainMenu class instead of trying to change the values again

[rough granite]

Yeah

[gentle bone]

i had some similar problem .. try switching the positions.. first the visibility then the lockstate..

[rough granite]

Well i doubt this is it their MainMenu class only changes the Cursor states once but the fps controller is changing it once per frame so the minute it's changed if the fps controller bool is set to true it will never show

[gentle bone]

yeah probably.. but as said i had some similar problem w a while ago.. it fixed my problem just swapping them around...

[red igloo]

@rough granite I decided to do it this way https://paste.ofcode.org/EnBZQT6rtZsyv5UH84EKta and it works but when I unpause the game how would I make the cursor disappear? I have to click to make it disappear

I think I am just going to let the main menu script handle hiding/showing the cursor

[rough granite]

No sure :/

[primal trench]

if I want a character that's physics based (sliding, wall jumping ect.) is it Really best to use a character controloler? is there another component or plugin that has more stuff built uin like godot's or is this really the best wy

there is the rigidbody

[primal trench]

isn'

t that

not reccomended for players

or is it fine

[frail hawk]

yes it is fine..

[cosmic quail]

the best way is to make a kinematic character controller
and yes there are ready made ones with a bunch of functionality built in, on the asset store for example

kinematic character controller?

[cosmic quail]

yes

what's that?

i cant guarantee that this is the best one tho

[round mirage]

Hello 🙂 i made this scriptable object but i would like to know how can i get this data in my script ?

[rough granite]

You make a serialized reference like a public float that you fill out in the inspector

[round mirage]

i know but how can i get these value in my other monobehaviour script ?

[wintry quarry]

Again, get a reference to the object and use the reference

[round mirage]

Ohhhh like public ScriptableObject wood; ?

[polar acorn]

You would use the type that your SO actually is rather than the type ScriptableObject

In this case, Item

[round mirage]

public Item wood; ?

[wintry quarry]

No it's called Item

[round mirage]

and so after i can do something like wood.id ?

[topaz chasm]

should ı make my inventory system on a dont destroy on load gamemanager object to save it

[frosty hound]

No, the smarter thing would be to use a separate scene to hold objects that should persist throughout the game.

And then load your gameplay scenes asynchronously. That way your Root scene (or whatever you call it) that contains your inventory object and any other managers for that matter, will also be available.

my boss from the game im doing spawns some minions, in the health script because i used an observer pattern i need an event, and each minion needs their own, how can i every time that a minion spawns give their own events?

Hi, I am following the Junior Programmer Pathway, and I am stuck at "Lab 3 - Player Control". There is no Project Files to download, anyone know where I can get them?

[round mirage]

Hello again 🙂 i would like to change My image sprite but i think i dont get the component correctly. someone know what is wrong ? Icon = gameObject.GetComponentInChildren<Image>(); txt = gameObject.GetComponentInChildren<TextMeshPro>(); Icon.sourceImage = sprite;

[frail hawk]

create direct references instead of doing this mess

[round mirage]

but i will have to make this reference in every slots 🥲

does something to get a child by his name exist ?

[grand snow]

This is why UI like this gets built by code and why each "slot" should use its own component to ref the image and text

use layout groups to do horizontal/vertical/grid layout automatically

[round mirage]

No way exist to get my image component from my child ??

[grand snow]

Yea what you did works but its not great

currently you need something like

foreach(GameObject slot in slots)
{
  slot.GetComponentInChildren<Image>().sprite = blah;
}

better to have

foreach(Slot slot in slots)
{
  slot.image.sprite = blah;
}

[thorn kiln]

So, for my unity pathway personal project, I wanted to make a game where you destroy cubes by jumping on the top of them, the problem I'm having though is that I don't think I've actually been taught any way to move a 3d shape towards the player other than addForce, which just seems to make the blocks very "slippy"

[round mirage]

the script i am making will be in every slots so i dont have to do this ?

[grand snow]

yea you can make a new script called "Slot" to let you reference the image and text of each slot easier!

then have a serialized List<Slot> slots

[round mirage]

I made this to get my child but it dont change the picture and the text 🥲

    public int id;
    public string Name;
    public Sprite sprite;
    private Image Icon;
    private TextMeshPro txt;
    private GameObject logo;
    void Awake()
    {
        logo = gameObject.transform.Find("Icon").gameObject;
        Icon = logo.GetComponent<Image>();
        txt = gameObject.GetComponentInChildren<TextMeshPro>();
    }
    void Start()
    {
        ReloadSlot();
    }

    // Update is called once per frame
    void Update()
    {

    }
    public void ReloadSlot()
    {
        txt.SetText("x" + numb.ToString());
        Icon.sprite = sprite;
    }```

[frail hawk]

is this script on each of your Slots

[round mirage]

i tried to put it on only one but yes it is supposed to be on every slots

[grand snow]

If its on the prefab it will be on each
second use [SerializedField] instead of find and GetComponent

the you can just drag both in via the inspector ui

[round mirage]

ok i will try

[thorn kiln]

Hmm, I got it to not be slippy with transform.Translate, now I have the problem that it's ignoring that Ifroze it's Y axis, so now it's flying and even sinking into the ground somehow

[wintry quarry]

If you're moving a Rigidbody via the Transform you're doing it wrong

[thorn kiln]

Would it work if I just transformed the object itself?

[wintry quarry]

which object? Isn't that what you're doing?

You should back up and explain what you're trying to accomplish exactly

[thorn kiln]

I said it here

[wintry quarry]

you could just set its velocity directly

if you don't want to deal with realistic momentum

[thorn kiln]

The problem is, the pathway course is asking me to design how enemies move while only having taught me transform.Traslate and AddForce

And I dont think either are great for my idea

[wintry quarry]

they are not

I'm telling you a better alternative

note that what you want is possible with AddForce it would just require more complex calculations than what you are probably interested in performing

and it would be simpler to just set the velocity directly

[thorn kiln]

That right?

I dont really know how to impliment velocity, so this is a bit tricky

[grand snow]

you can use Rigidbody.MovePosition() instead which will do velocity changes for you

[wintry quarry]

Do what it says

[wintry quarry]

I don't recommend this

MovePosition doesn't respect collisions

There's no good reason to use it over velocity here

It's really for kinematic bodies

[grand snow]

It does because its still uses velocity to move

but you will keep pushing into things

[wintry quarry]

It will happily put your non kinematic bodies inside of walls

Try it and see

[grand snow]

not what I have observed 🤔

oh shit is 3d and 2d different

ffs unity

my mistake I used the 2d version last

[thorn kiln]

So how would I use linear velocity to make it move towards the player

[grand snow]

set the velocity to something to go towards some position
Vector3 dir = target - self; (not normalized)

rb.linearVelocity = dir.normalized * multiplier

[thorn kiln]

Nice, that actually works

[grand snow]

you may wish to clamp the magnitude of the new velocity using Vector3.ClampMagnitude() but should mostly work

[thorn kiln]

What would that accomplish? I haven't had to deal with clamp yet

[bleak glacier]

Could anyone point me in the right direction here?

I'm looking to create an inventory system, and there will be some pre-existing items that the player can add to their inventory.

However, I need to create an item system that allows to the player to create items with custom values and descriptions. I'm assuming that I'll be using structs, but beyond there I don't really know where to start. Can someone point me in the right direction?

[grand snow]

Actually ignore me in this situation the speed it moves at is consistent as we normalise the dir vector
If we omitted that then we would wish to clamp magnitude

[thorn kiln]

Ah yeah, my look direction is normalized

    void Update()
    {
        Vector3 lookDirection = (player.transform.position - transform.position).normalized;

        enemyRb.linearVelocity = lookDirection * speed;
    }```

(Not that I actually understand what that does)

[wintry quarry]

You can use structs or classes, sure.

.make a struct or class that describes an item, and make a way to:

• display them in an inventory
• create them as a player

[rotund root]

is there any smart way to make my 2d sprite blink repeatedly? (this is for when taking damage)
this is the method i could think of and i know it looks stupid

IEnumerator TakingDamage()
{
  while(takingDamage)
  {
    invincible = true
    defaultSprite.SetActive(ture);// ---------
    yield return new WaitForSeconds(0.5f);//-- this 4 lines repeat 3 times
    defaultSprite.SetActive(flase); //-------- not pasting them all out
    yield return new WaitForSeconds(0.5f);//-- cuz i dont want to clog the chat
    invincible = false
    takingDamge = false
  }
}

[wintry quarry]

Use a loop

[bleak glacier]

I just don't want to start and find out that whatever I do will make it impossible for a player to do the same. Are there any risks there?

[wintry quarry]

Never repeat code like this

[wintry quarry]

You really need to start trying stuff. I'm not really sure what risk you're worried about. Design it with the object being created at runtime in mind that's all

[grand snow]

normalizing a vector changes its length or magnitude to be 1

le google

[rotund root]

thanks! i forgot loop is a thing

[thorn kiln]

Yeah, thats the jargon answer though. I don't really understand what that means in a practical sense so I dunno how and when to implement it

[wintry quarry]

It's only jargon if you don't understand what the magnitude of a vector is

It's just the length of the line

[grand snow]

google will define all these terms for you

and are important to learn for working with 3d vector maths

[wintry quarry]

The point of it is to have a vector that can easily be multiplied by something (such as the speed here) to get a vector with a desired magnitude since a magnitude of 1 is the multiplicative identity value

[thorn kiln]

It's all over my head atm

[polar acorn]

What it means in the practical sense is that it makes the length of the vector 1. You use it when you want the length of the vector to be 1

[thorn kiln]

I'm still very beginner

[grand snow]

well when getting a direction vector its best to normalise so it makes things consistent and not change based on the distance

(unless we desire such an effect)

[slow blaze]

 void Update()
    {
        Vector3 target = Player.transform.position - transform.position;
        if (enemyState == STATE.Aiming)
        {

            Aiming(target);
        }
        else if (enemyState == STATE.Dashing)
        {
            Dashing(target);
        }
    }

  

    void Dashing(Vector3 target)
    {
        //logic to dashing will be implemented later
        transform.Translate(3f * Time.deltaTime, 0, 0);


    }

    private enum STATE
    {
        Aiming = 0,
        Loading = 1,
        Dashing = 2,
    }


    void Aiming(Vector3 target)
    {
        //Keep looking at the player. 
        float angle = Mathf.Atan2(target.x, target.z) * Mathf.Rad2Deg;
        transform.rotation = Quaternion.Euler(0, angle, 0);
        StartCoroutine(waitToChangeState(3f, STATE.Dashing));
    }

    IEnumerator waitToChangeState(float delay, STATE state)
    {
        yield return new WaitForSeconds(delay);
        enemyState = state;
    }```

Hey guys I want to change the enemy state based on a delay, and this is what I came up with. I don't know if the repeated calling of  (StartCoroutine(waitToChangeState(3f, STATE.Dashing));)
Will cause a problem?
Is there a better way to change states on a timer?

[wintry quarry]

yes it's going to cause a problem, you're starting a new coroutine every frame

[slow blaze]

yeah I felt that would be the case

[wintry quarry]

that seems like a coroutine you only would want to start when you first enter the aiming state

in the case of this script it seems like maybe in Start

[slow blaze]

Thing is, I will enter the aiming state again.
I haven't written it yet but after dashing, it's going to return to Aiming state

And it's supposed to go back and forth

Dash and Aim, Dash and Aim

[wintry quarry]

right that doesn't change my answer

you would start the coroutines when you enter the states

it might make your code cleaner to make a function for entering a state

instead of just calling:
enemyState = state;

you woul do:

ChangeState(state);```

in ChangeState you might have a switch:

void ChangeState(STATE newState) {
  enemyState = newState;
  switch(newState) {
    case STATE.Dashing:
      StartCoroutine(waitToChangeState(3f, State.Aiming));
      break;
    case STATE.Aiming:
      StartCoroutine(waitToChangeState(3f, State.Dashing));
      break;
  }
}```

something like this

you can put whatever behavior you need in this switch, to handle what needs to happen when you first enter any given state

Simple example here for having them sort of "pingpong" with each other^

but still extensible for other states

[grand snow]

perhaps the switch() is confusing for such an example

[slow blaze]

So where would the function call be?
If I call it within the functions Aiming() and Dashing() wouldn't it still create a Coroutine every time?
If I call it in Start how can I call it again?

[wintry quarry]

So where would the function call be?
Every place where you change the state

[wintry quarry]

If I call it within the functions Aiming() and Dashing() wouldn't it still create a Coroutine every time?
That's not where you're changing the state

If I call it in Start how can I call it again?
There's nothing that prevents you from calling it in multiple places

The only place you're currently changing the state is here:

    IEnumerator waitToChangeState(float delay, STATE state)
    {
        yield return new WaitForSeconds(delay);
        enemyState = state;
    }```

so that's the only place you would put the call to the ChangeState function to replace what you have now

However you also need to put it in Start

to kick things off

[slow blaze]

Oh yeah I get it now thanks
it's going to recursive call through the Coroutine of waitToChangeState

[wintry quarry]

yes

[slow blaze]

yeah thats a lot better thanks for helping

[round mirage]

Hello again 🥲 i always get this error when i try to do the function addItem() i am trying to fix the bug but i dont find where is the problem.public void AddItem(int itemID, int amountToAdd) { slotVerified = 0; for (int i = 0; i < slot.Length; i++) { if (slotTakenID[0] != itemID) { slotVerified += amountToAdd; } else { avalaibleSlot = i; } } if (slotVerified != slot.Length && item[avalaibleSlot].stackable == true) { scriptSlot[avalaibleSlot].numb++; } else if (slotVerified == slot.Length) { for (int j = 0; j < slot.Length; j++) { if (slotTaken[j] == false) { slotTaken[j] = true; slotTakenID[j] = itemID; scriptSlot[j].numb += amountToAdd; scriptSlot[j].Name = item[itemID].Name; scriptSlot[j].sprite = item[itemID].sprite; scriptSlot[j].taken = true; scriptSlot[j].ReloadSlot(); break; } } } } if (Input.GetKeyDown(KeyCode.E)) { inv.AddItem(0, 1); } if (Input.GetKeyDown(KeyCode.A)) { inv.AddItem(1, 1); } if (Input.GetKeyDown(KeyCode.F)) { inv.AddItem(2,1); }

[low copper]

Based on my reading I thought I didn't need to have a yield return line in my SceneRedirect method. However I am getting compiling errors "not all code paths return a value". Any thoughts?

using UnityEngine;
using UnityEngine.SceneManagement;
using System.Threading.Tasks;
using System.Collections;
using System;

public class InitScript : MonoBehaviour
{
    public GameObject logo;
    private Renderer logoRenderer;
    public float AnimationSpeed = .25f;

    private void Awake()
    {
        logoRenderer = logo.GetComponent<Renderer>();
    }

    void Start()
    {
        StartCoroutine(AnimationSequence());
    }
    private IEnumerator AnimationSequence()
    {
        yield return StartCoroutine(AnimationLogo());
        yield return StartCoroutine(SceneRedirect());
    }

    private IEnumerator AnimationLogo()
    {
        float dissolveCurrent = 0.8f;
        while (dissolveCurrent >= 0)
        {
            dissolveCurrent -= AnimationSpeed;
            logoRenderer.material.SetFloat("Stage", dissolveCurrent);
            yield return null;
        }
    }
    private IEnumerator SceneRedirect()
    {
        //SceneManager.LoadScene("Scenes/Intro/Loading/Loading");  
        Debug.Log(AnimationSpeed);
        // yield break; comment out causes error
    }
}

[wintry quarry]

there's absolutely no reason to use a coroutine if there is no yield in it

[low copper]

ah ok. Just just call SceneRedirect at the end of AnimationSequence. That makes sense. I knew something was up.

[wintry quarry]

yeah just make the return type void

[low copper]

thanks. I appreciate it.

[polar acorn]

What line is the one the error is on?

[round mirage]

Unity talk about cs.38 so this one ```` if (slotTakenID[0] != itemID)```

[polar acorn]

Then it would seem that slotTakenID is null

[round mirage]

oh

ok thank you 🙂

[round mirage]

i tried to set slotTakenID at -1 but i still have the same error

[polar acorn]

What do you mean "set it at -1"? It appears to be a list of some kind

you can't set a collection to -1

[round mirage]

it is an int array why it cant be -1 ? for (int i = 0; i < slot.Length; i++) { scriptSlot[i] = slot[i].GetComponent<slotScript>(); slotTakenID[i] = -1; }

[polar acorn]

Because an int array is not an int

A bag of potato chips is not made of potato

Your array is null

[round mirage]

oh

so what can i do to fix this ?

[polar acorn]

Don't try to use null as if it were an array

Where do you assign a value to slotTakenID?

[silk night]

you have to initialize your array

[round mirage]

    public GameObject[] slot;
    private int[] slotTakenID;
    private bool[] slotTaken;
    private int slotVerified;
    private int avalaibleSlot;
    private slotScript[] scriptSlot;
    void Awake()

        slotVerified = 0;
        for (int i = 0; i < slot.Length; i++)
        {
            if (slotTakenID[i] != itemID)
            {
                slotVerified += amountToAdd;
            }
            else
            {
                avalaibleSlot = i;
            }
        }
        if (slotVerified != slot.Length && item[avalaibleSlot].stackable == true)
        {
            scriptSlot[avalaibleSlot].numb++;
        }
        else if (slotVerified == slot.Length)
        {
            for (int j = 0; j < slot.Length; j++)
            {
                if (slotTaken[j] == false)
                {
                    slotTaken[j] = true;
                    slotTakenID[j] = itemID;
                    scriptSlot[j].numb += amountToAdd;
                    scriptSlot[j].Name = item[itemID].Name;
                    scriptSlot[j].sprite = item[itemID].sprite;
                    scriptSlot[j].taken = true;
                    scriptSlot[j].ReloadSlot();
                    break;
                }
            }
        }
    }```

my array get his value only at the end of additem()

[polar acorn]

In Awake you create a new variable, also named slotTakenID, and create an array for that. The variable then ceases to exist at the end of the function

You probably want to use the one you've defined as a private variable instead

[silk night]

man kudos to your eyes, i couldnt find what was wrong 😄

as a sidenote, have you done !ide ?
It should warn you about overriding properties

oh you mean i only created the array for awake() but dont exist for addItem() ?

[silk night]

in awake your are using a local variable instead of your property

[round mirage]

oh

        bool[] slotTaken = new bool[slot.Length];```
i did this to set the size of my array but i suppose this is this who make this bug ?

[raven wolf]

CHAT GPT wtf i wonder if this works im not a programmer so I have no clue if this code is viable or not like damn im hapy for you chat gpt

[polar acorn]

Chat GPT
Probably doesn't

[polar acorn]

You need that code, but you need to not be creating a new variable

You need to use the one you already have

When you do [type] [name] = [value] that creates a new variable

If you want to assign a value to an existing variable, it's just [name] = [value]

[raven wolf]

not suprised but i do want to install unity and do it rq

[polar acorn]

Go ahead but you're probably not gonna get anyone here to want to debug the slop so you're on your own

[raven wolf]

im not here tryna develope no game 🥀

[rich adder]

why not just learn how to do it properly ? so you know what the code is actually doing incase it most definitely will break

[round mirage]

        slotTaken = new bool[slot.Length];
        scriptSlot = new slotScript[slot.Length];``` ?

Over the past few weeks, I’ve been developing an XR Grab Interactable system for my VR guns. My goal is to make it so that if the player grabs near the trigger, the gun will use a preset attach point rather than dynamic attachment, while still allowing the rest of the gun to use dynamic attachment. I’ve tried a few approaches, but so far none have worked as intended. I’m now looking for advice on the best way to achieve this.

[mystic flume]

What does the new unity input system do and how do you even use it

oh yeah heres the error ```NullReferenceException: Object reference not set to an instance of an object

[wintry quarry]

Assuming it's this line:
for (int i = 0; i < GameData.players.Count; i++)
Then GameData.players is null

make sure it's assigned before you try to use it

[cerulean bear]

ohhhh ok alr

1. It gives you an API to handle user input

[cerulean bear]

alr thx it works now

[bleak glacier]

So I'm being really stupid: I'm struggling with references. I was using static variables, and I realize that was stupid. I'm trying to backtrack.
levelDropCTRL = GameObject.FindGameObjectWithTag("LVL").GetComponent<LevelDropCTRL>();

I'm not sure how to make normal, non-static variables accessible like I did when they were static.

I was able to do stuff like this:

anotherconMod = AbilityScores.conMod;

[grand snow]

you talking about public fields/properties?

using the class name is only possible for static members

otherwise its used on a class instance

[bleak glacier]

I have public integers that I need to access. They were originally static because it seemed easier to access those values.

[spring otter]

You need to GetComponent to one particular instance of that class

Then you'll have access to public variables inside that instance

[grand snow]

This to me shows a lack of understanding of object oriented programming. Best read up on c# basics and c# classes.

[bleak glacier]

Yeah it would show you that

[grand snow]

Some things can be static but depends on the field/method

[spring otter]

public class Player
{
  public int health;
  private int maxHealth;
}

public class SomethingElse : MonoBehaviour
{
  public Player onePlayer;

  void Start()
  {
    onePlayer = GameObject.FindObjectsOfType(Player).GetComponent<Player>(); 
    onePlayer.health += 1;
  }
}

This shoud work I believe

Static variables are a singular instance in the software IIRC

[grand snow]

good lord no that wont

[spring otter]

lol really? am I forgeting something?

[grand snow]

many things 😆

[bleak glacier]

So why could I do this with static variables but not with normal variables?

[spring otter]

Well I tend to GetComponents only on self of set them through the inspector

[bleak glacier]

It was so much easier when I could just reference the tagged object, and pull variables from every script on that object

[spring otter]

Ah right I forgot to set a value for int lmao

[grand snow]

static things do not exist on a class instance so are access using the class name
That can be "easier" but depending on its task that may be the wrong way to do things

public class Player : MonoBehaviour
{
  public static Player Instance;

  void Awake()
  {  
    Instance = this;
  }
}

Singleton pattern

[spring otter]

You can make the object public and set the reference through the inspector, do you know how to do that?

[grand snow]

a static field to let us access a player instance

[spring otter]

If you do you can access public variables from that component by calling the reference name

[grand snow]

learn more: https://unity.huh.how/references/singletons

[bleak glacier]

Yeah I guess I could do that

[spring otter]

public class Player
{
  public int health = 0;
  private int maxHealth = 10;
}

public class SomethingElse : MonoBehaviour
{
  public Player onePlayer;

  void Start()
  {
    onePlayer = FindAnyObjectByType<Player>(); 
    onePlayer.health += 1;
  }
}

Try this, I think it should work now

Btw the "FindStuff" in Unity is not a very good way of doing stuff, it should only be used in small projects/quick prototyping

In that example maxHealth wont be accessible because it's private, obviously

[grand snow]

pretty sure you can only Find() unity objects

[rough granite]

Yeah the provided code wouldn't work

[spring otter]

FindAnyObjectByType<Instantiator>()
I'm using this right now in my prototype and it's working

[grand snow]

yea its a monobehaviour i bet

[spring otter]

Yes

[grand snow]

have a good read what Player is 🤔

[spring otter]

Ah right

Missed that, but his player is most likely a MonoBheaviour

[grand snow]

anyway this doesnt help with what they should actually learn

Ideally c# is understood well outside of the context of unity

[spring otter]

Well, he seems to be interested in using Unity, not plain C#

[spring otter]

Did you manage to make it work?

[bleak glacier]

I'm blundering through. I'll probably get there eventually

[spring otter]

https://www.youtube.com/results?search_query=unity+how+to+access+other+scripts

[grand snow]

yeesh

!learn is the way

[eternal falcon]

:teacher: Unity Learn ↗

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

[spring otter]

Just keep in mind these "Find" methods in Unity are just placeholder, you should be Getting Components on self, through the inspector or setting them directly to the desired thing

[raven pilot]

you can always use unity without c# once you're familar with unity itself and you need to use c# learn it then

[grand snow]

Learning about c# lang concepts is always helpful. the microsoft docs are helpful and detailed

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

[raven pilot]

idk programming at all, but I'm wanting to learn. so starting with unity without it is more easier to not be overwhelmed. there's multiple ways to do things in unity without the use of c#, learn it step by step, you're just now learning you're suppose to make mistakes and not understand certain things.

[grand snow]

You can get buy but there will come a point where the lack of understanding of OO programming will fuck you over
I was lucky I already knew java and c#

Knowing that components are instances and how GC works helps with many things down the line

[raven pilot]

gotta start somewhere 🤷🏽

[spring otter]

Wait you can say swear words here? Nice

[bleak glacier]

I don't know how I didn't find this video. Thank you.

@grand snow I understand that if everyone put an incredible amount of time into learning all aspects of Unity and C# from one course, they wouldn't be in my position. So I apologize for that.

There was a time where I knew how to do that. A few summers off and it all goes away.

[grand snow]

no need to apologise, just important to know that you can learn about c# and about unity and to not presume learning about unity will teach you programming too.

its like going to unreal and expecting to learn c++ (you wont)

[raven pilot]

I mean truly idk unity at all, either I'm a beginner in all of this stuff so my question is How much can you get away with visual scripting vs c# anyways?

[bleak glacier]

I really should try to learn more c#. Like I said, I'm not a programmer nor even proficient in Unity.

I spend two hours today basking in my own stupidity trying to figure out why

Public float float;
float = int/4
Debug.Log(float);

my float refused to give me decimals. f.

[grand snow]

ah yes the old int/int problem

doing 4f would ensure it does float/float

[bleak glacier]

Correct

Why is that even useful?

It seems useless.

[spring otter]

You can try asking some of these questions to an AI, like ChatGPT, sometimes you're forgetting something simple and the AI can quickly point it out to you.

[grand snow]

Its how it works, 4 is an int literal but 4u is an uint literal ect

[rough granite]

Why are we suggesting ai here?

[bleak glacier]

I have done that a few times. GPT really doesn't understand referencing.

[grand snow]

there are ways to define a literal of other types!
🙏 plz do not ask AI

[rough granite]

It doesn't understand anything it's stupid no matter how much resources into training it

[bleak glacier]

That is an ignorant and emotional position to take. There are many things that LLMs are capable of doing.

[spring otter]

It's useful sometimes

[grand snow]

for a beginner to learn, id say no
for someone with knowledge already, yes (as you can better tell when it makes up shit)

[bleak glacier]

I feel like I was successful in picking up on what the shit was, but that's only because it contradicts itself.

[rough granite]

it contradicts itself to make you the user feel good

[spring otter]

Btw I'm not saying for people to blindly throw code at an AI and ask what's wrong, you can past small snipets of code, but it's better for you to analyze your problems and actually ask the AI for advice, if it doesn't work it won't work, then you can seek help with others

[bleak glacier]

If you mean that it is often pressured into lying to you to avoid contradicting you, this is true.

But in these instances, that didn't apply. It would tell me one thing in one chat, and another in another chat.

[rough granite]

and im gonna stay by it all it is a huge tree of weighted values that change bit value based off other similar crap.

[spring otter]

Why would you insist your broken code is working though?

You need to know HOW to prompt the AI too

[rough granite]

i meant in general not for coding you can ask it if god exists then say the opposite opinion and it'll changes it's opinion to agree with yourself

[raven pilot]

[spring otter]

I'm talking about using AI to help solve problems
Also AI is almost a Google on steroids, you can also find stuff that you saw once in your life by telling it some vague descriptions and it can find it, pretty impressive

[raven pilot]

at this point, kinda wish ai was never created and people just learned how to google shit and use stackoverflow or seek others for help but we're getting off topic of the channel, but that's my 2 cents.

i admit, I'm guilty of using it but I've disciplined myself not to rely on it and do my own research overall

[grand snow]

I always go to docs first when looking up something for a language or lib
I ask AI as a last resort but the vague shit I ask about often gives a made up answer so 🤷‍♂️

[raven pilot]

Now if we get started talking about integrating MCPs with it that might be a whole different conversation

[red igloo]

When using lerp is using the animation curve better to go about doing this than using time.deltatime?

[cosmic dagger]

Integrating the animation curve with lerp is peak. You give yourself a custom curve—basically an easing function . . .

that's the only way I use lerp . . .

[red igloo]

I know, I've seen videos about it and I'm excited to try just wanted to make sure lol.

[bleak glacier]

But we were talking about the usefulness of AI in coding. I think you got distracted.

[odd grotto]

😭

[bleak glacier]

Dude I'm going insane

I have all but one reference working

And there are no compiling errors, and I can't see anything wrong with the code

Ah my dumbass forgot to put in the renamed gameobject to the button controller. :}

[teal viper]

Debug

[cosmic dagger]

Why does the GameObject being renamed matter?

[bleak glacier]

Misspoke. I made a new game object and renamed it, and disconnected the old one. I then swiftly forgot to reconnect the new one

https://discord.com/channels/489222168727519232/1405710251608637511

So uh, problems again. Who's surprised? This time it's a pathing issue with files though.

[strong bane]

Hello, I have a question about cooldowns
Would this be "safe" from frame hitches ? I dont want to have longer attack intervals then what is set
```c#
public void AttackFromTransform(Transform ownerTransform)
{
if (weaponType?.attackProfile == null) return;

    cooldown -= Time.deltaTime;
    
    if (cooldown > 0f) return;
    
    Debug.Log(cooldown);

    weaponType.attackProfile.Attack(ownerTransform, firePoint, this);
    cooldown = parameters.attackInterval;
}```

[ivory bobcat]

What do you mean by frame hitches?

[strong bane]

like a "long" frame from low fps. idk if its something to really worry about, chatpgt mentioned it when i was asking if there was any possible bugs here.

[ivory bobcat]

Current, if a minute or two passed because of the game freezing you'll only get one attack and your attack cooldown will be set back to your interval value

[strong bane]

ah okay so ill just accumulate the time and not reset completely to fix?

[sour fulcrum]

ChatGPT is dumb lol

[ivory bobcat]

If you're wanting all attacks to be simulated.. you could do something like.. cs while (cooldown < 0f)//Replaces your if-statement { Debug.Log(...); weapon.attackPro... cooldown += parameters.attackInterval; }

[strong bane]

ah okay, this is what chatgpt recommended.
is this common practice?

[rough granite]

is this called per frame?

[strong bane]

yes. cooldown is a member of a "Weapon" class. my actor calls this method in its update method

[kindred path]

So I have code thats supposed to prevent you from not being able to reach the red square, but for some reason my rooms overlap with themselves, if you think you might be able to help me tell me and I'll DM you the code

[sour fulcrum]

No dms

[kindred path]

I’m just desperate cause I’ve been trying for 7 hours today to fix it

[eternal needle]

is weaponType a unity object? if so you shouldnt use ?. on it
usually you would just do as dalphat said and use cooldown += parameters.attackInterval so you are still keeping those extra extremely small values like if cooldown is currently -0.05
so you worry less, there is a max delta time anyways which defaults to 0.3 seconds. if your game freezes for 1-2 seconds, deltaTime will still be 0.3. i wouldnt worry about designing around massive hitches because you shouldnt have massive hitches in the first place. there would 100% be other bugs out of your control if the game could progress seconds at a time

[rugged beacon]

im just checking out r3 and i have no idea whats a reactive value is, anyone got basic an example or something for this in unity ?

[strong bane]

thanks for the details
and yes it is a unity object, why should i not use ?. on it? is there some issues it can cause?

[eternal needle]

https://docs.unity3d.com/ScriptReference/Object.html

The null-conditional operator (?.) and the null-coalescing operator (??) are not supported with Unity Objects because they cannot be overridden to treat detached objects objects the same as null. It is only safe to use those operators in your scripts if there is certainty that the objects being checked are never in a detached state.

[strong bane]

😮 ty, i wasnt aware of this. im new to unity. The little bits of info like this are appreciated

[rough granite]

Then make a thread and ask for help there no one here that can properly help is willing to chat in dms

[kindred path]

Broken random dungeon generation

[hot wadi]

Does anyone know any way for object to do certain tasks even if they start and stay inactive?

[sour fulcrum]

yeah sure

what makes you think you can't

this is not code

[cosmic dagger]

You can call methods on an inactive GameObject as long as you have its reference. Only Update methods aren't called when inactive . . .

[hot wadi]

I don't mean to call methods from inactive objects. I mean to get the inactive object do its own thing

Because getting references from a bunch of them is requiring me to fetch each object at a time in a loop, causing a delay at scene loaded

[naive pawn]

perhaps don't use Find or whatever then, use serialized references if possible, or if they're created at runtime, get whatever is spawning them to keep their references

[worn bay]

Hi, how do I make the the gameobjects projected from the camera to game view, to be also projected to the canvas in scene view?

[rough sluice]

Do someone know that why Free Look is working fine for Up and Down but not for Left and Right?:

private void Awake()
{
    //Cursor.lockState = CursorLockMode.Locked;
    //Cursor.visible = false;

    player = GetComponent<Rigidbody>();
    mobileInputs = new PlayerMobileControlsInputs();
    mobileInputs.Player.Enable();

    // Look input binding
    mobileInputs.Player.Look.performed += ctx => lookInput = ctx.ReadValue<Vector2>();
    mobileInputs.Player.Look.canceled += ctx => lookInput = Vector2.zero;

    // Free Look input binding
    mobileInputs.Player.FreeLook.performed += ctx => isFreeLooking = ctx.ReadValueAsButton();
    mobileInputs.Player.FreeLook.canceled += ctx => isFreeLooking = false;
}

private void Update()
{
    // Camera rotation (Y for player, X for up/down)
    float mouseX = lookInput.x * lookSensitivity;
    float mouseY = lookInput.y * lookSensitivity;

    rotationX -= mouseY;
    rotationX = Mathf.Clamp(rotationX, -80f, 80f); // prevent flipping

    cameraHolder.localRotation = Quaternion.Euler(rotationX, 0f, 0f);
    if(isFreeLooking)
    {
        // Free Look to rotate cameraHolder only
        cameraHolder.Rotate(Vector3.up * mouseX);
        //cameraHolder.Rotate(Vector3.left * mouseY);
    }
    else
    {
        // Normal Look to rotate player
        transform.Rotate(Vector3.up * mouseX);
    }
}

private void FixedUpdate()
{
    Vector2 moveInputs = mobileInputs.Player.Move.ReadValue<Vector2>();
    float speed = 2.0f;

    // Move in direction relative to camera's forward/right
    Vector3 moveDirection = cameraHolder.forward * moveInputs.y + cameraHolder.right * moveInputs.x;
    moveDirection.y = 0f;

    player.linearVelocity = new Vector3(moveDirection.x * speed, player.linearVelocity.y, moveDirection.z * speed);
}

[worn bay]

can't just move the holder + camera to be on size with the canvas since it relies on keyframing on absolute coordinates

[radiant jewel]

Hey all. I ran into one of those unused variable warnings on a catch exception (DOTS/ECS workflow with burst). Made no sense to me since debug is using it. My brain sometimes does this thing where it screams at me... it's my intuition. Something creeps up from the depths of my memory and, usually, triggers an out of the box answer... This time it was, "discard your hand, ex, and draw another." Now, that is not exactly what is going on here... but I think you will get the picture as this is how I handled it:

            catch (Exception ex)
            {
#if !BURST_COMPILE
                Debug.LogError($"GPU heightmap generation failed: {ex.Message}");
                _ = ex; // Prevent unused variable warning
#endif
                _ = ex; // Prevent unused variable warning
                return null;
            }

The first discard silences the debug variable warning and the second silences the Burst warning.

[grand snow]

The real solution would be to do catch(Exception) for burst.

[radiant jewel]

My understanding is that catch exceptions cannot be used inside of a burst block and that is why I used the #if !BURST_COMPILE but this works as well because it's not utilizing Burst in the method so it is safe. But I still discard after to silence the IDE.

// Managed method: safe to use exceptions. No BURST guards needed here.
private RenderTexture GenerateHeightmapGPU(TerrainGenerationData terrainData)
{
    //...previous code

    catch (Exception ex)
    {
        Debug.LogError($"GPU heightmap generation failed: {ex.Message}");
        _ = ex; // LDL: Discard(ex) glyph to appease analyzers
        return null;
    }
}

[grand snow]

My suggestion is to have 2 catch blocks, one for burst and one not to solve the issue without using discard

[radiant jewel]

Tried it. Still got an IDE warning on Rider, VS, and VSCode. So... not sure why that would be unless catch is not allowed in a burst block.

[grand snow]

your ide has no idea what burst is and id expect an error to be printed in unity if its not fully compatible with burst

No idea if exceptions even exist in burst code

#if BURST_COMPILE
catch(Exception)
{
    return null;
}
#else
catch(Exception e)
{
    
}
#endif

does this work?

[fallen cosmos]

Does anybody know is it possible to implement asset picking from asset bundles by implementing a custom SearchProvider?

I want to make an SDK that ships a Unity project in which you work with original assets packed in a form of asset bundles, but at the same time I need to somehow support native workflow of using these assets in a project as if they were in your AssetDatabase

The only thing that I could find in regards to this is to create a custom SearchProvider, which is supposed to be what I am looking for but I feel like there is some caveat that I am not seeing

[radiant jewel]

It took a bit of work, as it was being incredibly picky. This version of yours works without IDE warnings or errors.

#if BURST_COMPILE
    catch (Exception)
    {
        // Burst jobs can’t throw – bail to safe default
        return null; // must match RenderTexture return type
    }
    #else
    catch (Exception ex)
    {
        Debug.LogError($"GPU heightmap generation failed: {ex.Message}");
        _ = ex; // LDL discard glyph
        return null;
    }
#endif

If I do not discard I get the error. Every time. Whether a catch block or burst or not.

[grand snow]

well we can clearly see that ex is used so that doesn't make sense

[radiant jewel]

As I said in the OP. lol. It is used, but I have to discard it anyway.

[balmy vortex]

Does anyone know how to stop stuff from clipping into eachother like this?

kk thanks

how do I actually convert my current code (https://paste.mod.gg/rapaytpkirqx/0) to use that though?

cuz like rn I need to change the actual direction of every input since the camera rotates

[grand snow]

a common way is to change the rigidbody velocity to move or using AddForce()

see similar convo yesterday: #💻┃code-beginner message

[naive pawn]

btw, if you have a rigidbody you should just not modify the transform at all and let the rigidbody manage it

just as a general tip

[rough sluice]

Currently my character uses W, A, S, D keys to move and I have created 4 UI buttons with on-screen button component with binding W, A, S, D for moving chacater to let mobile players move character but now what should I do to use on-screen stick component button for player movement instead of 4 UI buttons for player movement?

[balmy vortex]

did this but it makes the movement super slow for some reason

if (moveRightAction != null && moveRightAction.IsPressed())
        {
            Debug.Log("hey lets move right");
            var rotation = Quaternion.Euler(0, _camera.rotation.eulerAngles.y, 0);
            var direction = Vector3.right * speed * Time.deltaTime;
            var rotatedDirection = rotation * direction;

            rb = GetComponent<Rigidbody>();
            //transform.Translate(rotatedDirection);
            rb.linearVelocity = rotatedDirection;

        }
``` ^^ what I'm using rn

it's still "moving" but it's like barely even noticable

@naive pawn @queen adder

[keen dew]

Don't multiply velocity by deltatime. If it's still slow after removing that, increase the speed value

[balmy vortex]

kk

[grand snow]

if using input system unity has pre made on screen controls to work with a vec2 input (I think its a sample)

[balmy vortex]

[grand snow]

why is this done again and again?
rb = GetComponent<Rigidbody>();

modifying velocity will break jumping because if we override y vel to be 0 the rb will no longer fall

you can instead get current velocity, modify x,z only and re assign

[balmy vortex]

well how do I do that?

[keen dew]

The simplest way in that code is rotatedDirection.y = rb.linearVelocity.y; before assigning

[balmy vortex]

ok so like this works but now it's sliding like there's no friction on the ground (which ? there might not be ?)

[frozen nimbus]

I used to many AI to help me code, I feel like a fake dev these days

[balmy vortex]

not sure

[rough granite]

Not sure about the friction thing but why are numbers being logged every half a second or so?

[balmy vortex]

it's for a different script, you can safely ignore it

[balmy vortex]

^^ there's also this now which isn't great

[vital helm]

you need to add a physics material to the collider i think

[rough granite]

Well no i was curious cause logs do slow down the fps quite a bit especially when there are a lot.

[balmy vortex]

which one?

or like wdym

[vital helm]

the player capsule collider

[vital helm]

this thing

you can tweak stuff from there

[grand snow]

the player having high friction helps it not slide when not moving but ofc will require more speed to move

also its often a good idea to greatly reduce how much input changes velocity when not grounded

[balmy vortex]

idk why but changing this also nuked diagonal movement ^^

code rn for context --> https://paste.mod.gg/hzsqajykrhkn/0

[grand snow]

I don't see what you mean in the video gimme a sec

Hangon a sec what is this bizarre input

It should be a vector 2

Wasd going into a single vec2 (with a normalizer too)

[balmy vortex]

well how do I do that?

[tidal tide]

Just curious how come you've decided to put each input direction into it's own input action, there's nothing wrong with it but it seems a bit inefficient to me, you could bind all movement inputs into one action that way you get all inputs as a single vector2 and you use it as you need or am I wrong here

[tidal tide]

You can have multiple bindings in a single action and have the value type of the action as a vector2

[balmy vortex]

maybe but idk how to actually code it in

[balmy vortex]

also dunno how it fixes this ^^

[balmy vortex]

or this ^^

[tidal tide]

It's not done in code it's done in your input system action setup where you create the inputs for left right up and down based on wasd, you can have them all in one single action, then that gives you the ability to cast them into a vector2 and you can normalise them easily to fix the diagonal speed issue otherwise you'll have to build a vector2 out of all 4 inputs to normalise them which is messy

[round mirage]

Hello 🙂 someone know why i cant disable my Image component ?? public Image Icon; Icon.enabled = false;

[polar acorn]

What's stopping you?

[round mirage]

me ?

[polar acorn]

Yeah. What's stopping you from doing that?

Is there an error? Have you actually tried it and seen if it works?

[thorn rune]

I'm coding an enemy that patrols an area by going between waypoints on a Navmesh. I want the enemy to randomly stop moving, rotate 360 degrees, and then continue - in a scanning motion to try and catch the player. The enemy currently just randomly rotates partially while moving straight forwards, causing it to go off the path and act erratically. What's going wrong?

IEnumerator ScanForPlayer()
{
    // Stops new coroutine starting until this one ends
    isScanning = true;

    // Stops agent from moving
    agent.isStopped = true;
    canMove = false;

    // Set agent velocity to zero
    rb = GetComponent<Rigidbody>();
    rb.velocity = new Vector3(0, 0, 0);
   
    // Failsafe to stop routine after 1000 runs
    int failsafe = 0;

    // Stops rotation once it reaches 360
    while (rotationAngle < 360.5f || failsafe < 1000)
    {
        failsafe++;
        transform.Rotate(Vector3.up * Time.deltaTime * -100);
        if (rb.transform.localRotation.y <= 3.6)
        {
            rb.transform.Rotate(0, 0, 1.0f * Time.deltaTime * 100);                
        }
        else
        {
            failsafe = 100000;
            //canRotate = false;
            yield return new WaitForSeconds(2);

            canMove = true;
            agent.isStopped = false;
            isScanning = false;
        }
    }
}

[round mirage]

i didnt tried but VS say i have an error

[polar acorn]

You have a script named Image or you have imported the wrong namespace. The Image class you are using is not the Unity UI one. Hover over the Image type in the variable declaration and see what class that is

[round mirage]

ok

[keen dew]

Nothing there changes rotationAngle, and checking localRotation.y is meaningless

it should be something like this:

float rotationAngle = 0;

while (rotationAngle < 360)
{
    float rotationAmount = Time.deltaTime * 100;
    rotationAngle += rotationAmount;
    transform.Rotate(Vector3.up * -rotationAmount);
    yield return null;
}

yield return new WaitForSeconds(2);

canMove = true;
agent.isStopped = false;
isScanning = false;

[tidal tide]

Have you seen how the default actions are configured?

[balmy vortex]

well ya changing this thing vvvv is easy but how do I set up the inputs in the code itself with it?

like what do I replace the stuff in here with? https://paste.mod.gg/pqfbufznieax/0

[round mirage]

It say i have the Microsoft and the Unity Image in the same time but i dont know how to have only the unity one

oh no i found how to fix it

ty 🙂

[tidal tide]

Good now in code you can set your private input action to reference that action and when you need the value, just use inputaction.ReadValue<Vector2>()
I'd recommend reading more on the input system on the documentation as well

[thorn rune]

He's now spinning uncontrollably the entire time he moves

[keen dew]

How are you starting the coroutine?

[thorn rune]

if (isScanning == false && proxDetect.canBeSeen == true)
{
    int scanChance = Random.Range(0, 10);
    if (scanChance == 1)
    {
        StartCoroutine(ScanForPlayer());
    }
}

This runs every Update, so if the coroutine is not running (isScanning is off) and the player is within a certain area, it starts the routine 1/10 times

If I coded it correctly

Which I'm now doubting... xD

[keen dew]

Yes but if the game runs say at 60 fps then 1/10 times each frame is 6 times per second

[thorn rune]

Oh

[dense current]

Yo i started learning c# yesterday and managed to code a double or nothing cmd game on visual studio i wanna try unity and take a step forward what are some good beginner projects that could help me learn scripting better?

[wintry quarry]

!learn

[eternal falcon]

:teacher: Unity Learn ↗

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

[wintry quarry]

Or if you want to just dive in and make stuff yourself Flappy Bird is a good one to start with

[balmy vortex]

I don't get it

[wintry quarry]

show how you set up the action - it seems like it's not configured properly

Looks like you probably have it set up as a Button action

[wintry quarry]

Oh I see - yeah the problem is you set up the bindings wrong

You need to create a new binding and choose "up/left/right/down composite binding" (in older versions maybe also called "Vector2 Composite")

then add all those keys to the composite binding

(and get rid of the bindings you have now)

[balmy vortex]

ok that works but the debug.log just spits these numbers out that change with inputs but like how do I actually know what key is being pressed here?

[limber turtle]

if i want to increase acceleration but have the same speed, should i just double movement force and drag? i'm trying to make movement during jumps feel smoother in my platformer but i'm not sure how to do it without doing something weird

if you jump and then start moving, it feels really slow and annoying to control

but giving the player a small movement boost when they start moving just feels weird

in the air, i mean

[rough granite]

0 would indicate nothing

Or it's failing to update

[wintry quarry]

you can use more drag or you can apply a speed limit in a different way

[limber turtle]

i'm not sure how to do that in a way that would feel natural

[wintry quarry]

you could also use a higher force for when you start moving than when you are continuously moving

[limber turtle]

i can't clamp because i want to use momentum for some things

[balmy vortex]

yes I know, the values change whenever each input is pressed, I just dont know what to do with them

[limber turtle]

that could work

[rough granite]

Wdym don't know what to do with them

[limber turtle]

i could double movement force until you're at half top-speed

thank you praetor

[wintry quarry]

the most basic way is to just check your velocity and clamp it in FixedUpdate (though this is not a perfect solution because Unity's game loop doesn't apply AddForce until AFTER fixedupdate)

[wintry quarry]

yeah there's all kinds of heuristics you can do. You'll probably need to spend some time tweaking it until it feels right to you

[limber turtle]

i can't clamp though, i plan on making abilities that will give you momentum instead of fixing your velocity afterwards

thank you for the force doubling idea though

surprised i didn't think of that myself lol

[rough granite]

Could have the abilities add to velocity after the clamp

[wintry quarry]

You might be interested in this (free) asset that has a "soft speed limit" feature that might satisfy your needs.
https://assetstore.unity.com/packages/tools/physics/betterphysics-selective-kinematics-244370

[limber turtle]

i think i'm alright as of now

i just want to use unity's built-in tools for now

[balmy vortex]

@wintry quarry ?

[limber turtle]

you could probably add something to the string on the line where you call the debug log

[wintry quarry]

generally you're not really interested in "which keys are being pressed" This vector is an input direction you can use in your game now.
E.g. you can more or less plug it into whatever movement system you're using

[limber turtle]

so it would be easier to know what you're looking at

[balmy vortex]

oh ok ty king

[balmy vortex]

where do I like actually put it though? bcs rn with just this I literally can't go backwards or forwards

[wintry quarry]

Is this 3D? Normally for 3D you'll need to "swizzle" the input vector - i.e. plug the y from the input vector into a z for your actual movement direction

because y is "up", and reight now you're just overwriting the y part with rb.linearVelocity.y

e.g.

Vector2 moveInput = move.ReadValue<Vector2>();
Vector3 moveInput3D = new(moveInput.x, 0, moveInput.y);```

[opal blade]

quick question: is there any way to make Rider recognise Unity hlsl symbols like the Light data type? i feel like i might need to add an include path but i'm still not really sure how

[brave compass]

You mean in a hlsl file to be used in a Custom Function in Shader Graph? This is only a problem there, since in normal shaders, you would include all the files that have these symbols in them.

It's possible that you can include the relevant files in here, if those include files have guards to ensure they won't be duplicated.

If you're using URP, try adding #include "Packages/com.unity.render-pipelines.universal/ShaderLibrary/Lighting.hlsl

[opal blade]

Yes, this was for a custom function

[opal blade]

unfortunately including this at the top of the file fixes the unrecognized symbols in Rider but it breaks the function in Shader Graph, citing an 'unterminated conditional expression' as well as these errors

[primal trench]

https://pastebin.com/PZJcuia0

I managed to fix the error, but i want to understand it, does anybody have any idea why calling the Handle Input Buffer function in Update would fix the movememnt speed? also is it okay for all this code to be in the player or would i want to seperatr

i've seperate non movement things like grappling

but all these relate to movement

my only theory for why not being able to jump is affecting movement speed is that it's somehow messing up input

i guess if i fixed it it doesn't really matter but I want to know why it's happening

[acoustic belfry]

Hi, how i can make my raycast bigger, or autoaim or smt
i mean cuz my shooting feels pretty wacky and i constantly miss the enemy, and i feel like that could go wrong

[frail hawk]

you´d have to use something else than rc

Spherecast would be a solution , but could cause other problems

[native flame]

how does using charactercontroller compare to a kinematic rigidbody?

for player movement

[acoustic belfry]

what kind of problems?

[frail hawk]

not pricesely enough maybe

[acoustic belfry]

pricesely enought?

also what is a spherecast?

in theory would be a kind of very long capscule?

[naive pawn]

basically yes

[acoustic belfry]

i mean, a capsule that would stretch from point A to hit B

[acoustic belfry]

oh

well, that seems pretty good

just a very small spherecast

[naive pawn]

you get a sphere and you send it in a given direction

[acoustic belfry]

haha

[acoustic belfry]

is optimized, right?

[frail hawk]

https://docs.unity3d.com/ScriptReference/Physics.CapsuleCast.html then this is even better for you

[acoustic belfry]

i thought i would have to do something complex for fix it

[acoustic belfry]

so, this IS a capsule that stretches then?

i mean, as spherecast is like a capsule that stretches, this would jsut be

or not? idk im guessing

[frail hawk]

yes

[acoustic belfry]

good

[frail hawk]

you will have to find out which one works better for you

[acoustic belfry]

why make spherecast in the first place?

i mean, spherecast makes a list of spheres into the direction

capscule cast makes a chonky raycast

isn't more usable the chonky raycast?

[naive pawn]

spherecast draws a sphere and casts it in a certain direction, drawing out a capsule
capsulecast draws a capsule and casts it in a certain direction, drawing out a.. rounded cuboid, i guess

#archived-code-general message

[acoustic belfry]

so then capsculecast was never a fat raycast, but a fat and tall racyast

ouch

[naive pawn]

depends on how it's oriented relative to the cast direction

[acoustic belfry]

i just want a fat raycast

[naive pawn]

that would be a spherecast

[acoustic belfry]

then a spherecast would be it

thanks a lot :3

[acoustic belfry]

can someone explain me why when i fire on this direction, this happens to the cast? (the line is tied to the cast)

[rocky canyon]

maybe its backwards?

[acoustic belfry]

i dont think so, is just when the angle is like this, cuz when the angle is more lowered it shoots forward

[frosty hound]

You need to learn to attempt some debugging before asking questions. A lot of your questions are just "what's wrong?" with a vague image.

[acoustic belfry]

sorry...

here's the code

 {
     Debug.Log("ShootedRifle is even shooting");
     rifle_amount--;

     // Get the mouse position in world space with correct depth
     Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);

     RaycastHit hit;
     if (Physics.SphereCast(ray, 3, out hit, Mathf.Infinity, demons))
     {
         Debug.Log("ShootedRifle has Shooted");
         Debug.Log("ShootedRifle hit 3D: " + hit.collider.name);

         EnemyBase enemy = hit.transform.GetComponent<EnemyBase>();
         if (enemy != null)
         {
             Debug.Log("ShootedRifle's enemy isn't null");
             enemy.TakeDamage(5, 1, 3, 3, transform);
         }

         lineRenderer.SetPosition(0, transform.position);
         lineRenderer.SetPosition(1, hit.point);
     }
     else
     {
         // Ray didn't hit — project forward from the camera or weapon
         lineRenderer.SetPosition(0, transform.position);
         lineRenderer.SetPosition(1, transform.position + ray.direction * 100);
     }
 }```

weird enought, this issue happens when the spherecast is used

why?

[bleak glacier]

So I'm using a save system, and it's working for all of my variables except the ones set by this dropdown menu. The debugs show, and everything else shows, that the variables themselves aren't the problem. The save system just won't save selectedNumber. Clearly there is something here that I don't know.

    {
    // this.levelDrop = data.levelDrop; 
    this.selectedNumber = data.selectedNumber;
    }

    public void SaveData(GameData data) 
    {
    // data.levelDrop = this.levelDrop;
    data.selectedNumber = this.selectedNumber;
    }```

[wintry quarry]

is this script attached to the camera, or an object at the same posotion/rotation as the camera?

[acoustic belfry]

the script is in player, wich is related to the camera

[wintry quarry]

what is this exactly? And which part isn't working? Saving, or loading? And where is a dropdown menu involved here?

[bleak glacier]

Saving and loading are broken for this value. selectedNumber = dropdown.value + 1

selectedNumber isn't broken though. It just won't save and load.

[wintry quarry]

broken how? What kind of debugging have you done?

you said "the debugs show" but which ones? I don't see any in the code you shared

Basically you've given us very little to work with here

[acoustic belfry]

i think i discovered the issue tho i dont know how to exactly fix it

the sphere is detecting the floor

to wich, if i make it dont do it, the ray works as a charm

issue here is

[naive pawn]

layermasks

[acoustic belfry]

yeah

the thing is, how i can make a raycast and an sphere cast work together?

[bleak glacier]

I mean, I've debugged selectedNumber, and that's working. The next that displays selected number obviously does that. Saving and loading works in every other script, and I haven't done anything differently. The only different about this script is the dropdown.value.

[naive pawn]

why did you say this then

i dont know how to exactly fix it

[acoustic belfry]

for this

cuz i dont know how to exactly do that

thats for why the exactly was for

[naive pawn]

they.. don't? they work independantly, you interpret the results together

[acoustic belfry]

huh

[naive pawn]

what are you trying to do

what is the purpose of each of those casts

[acoustic belfry]

as shoots, the spherecast must find an enemy at the same time the raycast must find a wall, if any of those both activate, it would count as shoot

[bleak glacier]

Yeah for some reason the whole code didn't paste. Lemme stick it in paste bin.

[naive pawn]

they don't operate over time

so what do you mean by "at the same time"

[acoustic belfry]

when i shot

idk, is just, i want it to work as a spherecast for one layer and work as a raycast for another

[acoustic belfry]

holup, what if i do this

{
    Debug.Log("ShootedRifle has Shooted");
    Debug.Log("ShootedRifle hit 3D: " + hit.collider.name);

    EnemyBase enemy = hit.transform.GetComponent<EnemyBase>();
    if (enemy != null)
    {
        Debug.Log("ShootedRifle's enemy isn't null");
        enemy.TakeDamage(5, 1, 3, 3, transform);
    }

    lineRenderer.SetPosition(0, transform.position);
    lineRenderer.SetPosition(1, hit.point);
}```

[native flame]

you really shouldnt be shooting your ray from the camera in a third person game

[acoustic belfry]

oh no, it fires from the player

it decides where to end by the camera

or atleasts thats what i feel like it does

[wintry quarry]

well it depends what the ray is exactly doing. It can make sense to do a raycast from the camera to the game world to determine where the player is clicking, but then a separate raycast from the player to the target for the actual shot

[native flame]

fair enough

[native flame]

a radius of 3 on your spherecast is way too high when your character is only 2 units tall, itll instantly hit the ground upon instantiation

[acoustic belfry]

yeah, that seems as the prob, thanks

issue now is, how i can make that a spherecast tries to hit the enemy, but doesnt phase away ignoring the ground layer using a raycast?

[native flame]

spherecast only interacts with enemy layer

raycast interacts with environment layer

[acoustic belfry]

yes, oh wait

i did it backwards

cuz i did, if sphrecast doesnt hits enemy then check if raycast hits ground. when it should be, if raycast hits ground then check if enemy should be check

no wait, that wouldnt work

i test it...

[bleak glacier]

@wintry quarry I figured it out. It was my fault.

[thick sedge]

hi

Raycasting 1 ray every frame is fine for both mobile performance and pc right?

[frail hawk]

if you use FixedUpdate nothing to worry about

[grand snow]

Nothing to worry about even in update

[keen dew]

Not even if you do 100 raycasts every update

[polar acorn]

Not what FixedUpdate is for

Even if it were a problem for perfomance, FixedUpdate doesn't magically fix that

[frail hawk]

FixedUpdate is not for physics ok

[polar acorn]

FixedUpdate is for things where the second derivative of time is important - the rate of change of the rate of change of time. This is mostly used for physics calculations

[frail hawk]

we are talking about Physics.Raycast right

[polar acorn]

Yes

Which is not, in any way, dependent on time

And especially not concerned with the rate of change of time

[frail hawk]

if you say the raycast doesnt belong into the FixedUpdate, why is the official documentation using this method then
