why is this modifying the z rotation?

[deft current]

omg you're a life saver that works, thansk so much 😭

[swift crag]

If you drag the script asset in, you'll only see "MonoScript" in the list of things you can call methods on

(and that doesn't even exist in the built game)

[tender stag]

it was because i was using slerp

[vast vessel]

what was that method that returned 0 if a vector3 was right in front of a direction, and 1 if the vector3 was behind the object?

[swift crag]

I am not aware of a method that does exactly this, but this sounds a bit like Vector3.Dot

Dot tells you how well two vectors align

[south sky]

Hey guys I wanna add a way to attack in my game. I dont have any sprites for attack so i wanted to make like a sword go around in a circle like terraria. Anyone know how to achieve this. Dont worry about hitboxes or collision detection just wanna know if anyone can do the spinny thing with a sword

[swift crag]

Two unit vectors produce 1 if they align, 0 if they're perpendicular, and -1 if they point in opposite directions

Ty for the help

[vast vessel]

how do i use Vector3.Dot so it returns -1 if a ct.go.transform.position is to the left, 1 if its to the right, and 0 if its on the front of transform.forward?

[solid bough]

i have a prefab on my enemy; i also have an enemyspawner that instantiates more enemies over time, but as soon as I destroy the original enemy, they obviously cannot get the prefab anymore since he died
whats the easiest way to fix it?

[swift crag]

what are you actually trying to do here?

what gameplay are you creating?

[vast vessel]

im trying to use the data for my animation controller

i have three animations, one for front melle attack, one for left, and one for right

[swift crag]

I'd suggest using Vector3.SignedAngle followed by Mathf.InverseLerp and Mathf.Lerp

SignedAngle gives you the angle between two vectors.

InverseLerp turns a range of values into 0..1

and Lerp turns 0..1 into a range of values

float angle = Vector3.SignedAngle(transform.forward, targetDir, transform.up);
float t = Mathf.InverseLerp(-90, 90, angle);
float result = Mathf.Lerp(-1, 1, t);

[vast vessel]

here is a diagram of what i want

[swift crag]

That might be backwards. I always forget which way the angles go

(so you might need Mathf.InverseLerp(90, -90, angle))

If angle is 45, Mathf.InverseLerp(-90, 90, angle) would produce 0.75

Then Mathf.Lerp(-1, 1, 0.75) spits out 0.5

If you need to snap this to -1, 0, or 1, you can use Mathf.Round

[swift crag]

using InverseLerp followed by Lerp is basically a remap

i dunno why Mathf doesn't have that baked-in

[vast vessel]

whats the difference between Vector3.Angle and Vector3.SignedAngle?

[swift crag]

Angle produces a value between 0 and 180

It can't distinguish between a left turn and a right turn

SignedAngle takes a third argument to figure out which way is left and which way is right.

[vast vessel]

so its the same but always positive?

[swift crag]

hence transform.up being included

[swift crag]

I'm not sure if it's exactly equivalent.

notably when the two vectors are not in the plane of the third vector

[vast vessel]

right

[swift crag]

Vector3.Angle(Vector3.forward, Vector3.right + Vector3.up);
Vector3.SignedAngle(Vector3.forward, Vector3.right + Vector3.up, Vector3.up);

I'm not sure how signed angle behaves there

I've always used it with vectors that I've already projected onto the Vector3.up plane

[vast vessel]

well, thanks, ill try it out and see if it works

[lethal elbow]

I'm currently working on a project involving scripts for a car, a spawn zone, and a GameManager in Unity. I've encountered an issue where I want the game to transition to a 'game over' scene when an object spawned by the spawn zone script touches my car. However, I'm having trouble implementing this functionality. Like I create a script for my object that get spawn but the code I use aint working. I would appreciate any help!

[swift elbow]

Use an OnTriggerEnter func and use SceneManager.LoadScene inside the function

You should read the docs if you want more info on how these work

[vast vessel]

can anybody tell me why the projectiles appear on that wall on the top?
they are supposed to be created on the transforms with the yellow gizmos(assigned in the flechetteDirection Transform array)

https://hastebin.skyra.pw/falasavoxe.csharp <- Hunter_Flechette.cs script placed on the projectiles (position assigned on line 41)
https://hastebin.skyra.pw/xoturuyaya.csharp<- AI_Hunter.cs script creating the projectiles (Init() func of the Hunter_Flechette script called on line 94)

[lethal elbow]

I have this but doesnt work

the gm is for my GameManager script that has the Game Over scene

[swift elbow]

What is scenefin()?

[lethal elbow]

Is the Game Over scene (some of my code is in french oop)

[swift elbow]

Yeah but what is in there

Can you show that?

[lethal elbow]

It supposed to bring to bring u to another scene

[swift elbow]

I get that...

How are you doing that though

[lethal elbow]

Just for context that part is also for some portals I have that if u collect them all it will bring u to You Won and if u dont Game Over

idk if that is why it cause some trouble for my code to work

[swift elbow]

Add debug.log statements first and then keep troubleshooting

[lethal elbow]

Ayt!

[willow scroll]

Are those included in build?

[lethal elbow]

I have a script for those element as well, those work fine.

[willow scroll]

What do you mean?

The those scenes included in build?

I'm talking about the scenes you're trying to load in the image above

[lethal elbow]

aah oop my bad

Yes they are in the build cuz they work with my portals when I collect them all and when I dont

[willow scroll]

And you say they're not loaded in the SceneFin method?

[lethal elbow]

I just cant make it work for my spawn object that when it come in contact with my car it doesnt bring me to the Game Over scene

[swift elbow]

Have you added debug statements yet...

[willow scroll]

Is the method even called?

Yeah, that's what you usually do before asking a question

You should figure out what part of the code isn't working

[lethal elbow]

I add a Debug.Log but it doesnt show anything

[summer stump]

Define "doesn't work"
Step 1 is adding debug.logs to figure out wgat runs and what doesn't

[summer stump]

Where? You want to add it before the if statement in OnTriggerEnter. And one IN the if statement

[willow scroll]

Yes, so the method isn't called?

[lethal elbow]

to this but Imma add it to the other script as well

[vast vessel]

push.

[polar acorn]

The Three Commandments of OnTriggerEnter:

1. Thou Shalt have a 3D Collider on each object
2. Thou Shalt tick isTrigger on at least one of them
3. Thou Shalt have a 3D Rigidbody on at least one of them

[willow scroll]

Is it a traditional English?

Also IsTriggerEnter is called when the object, containing the script, has isTrigger ticked

Otherwise OnCollisionEnter

[edgy prism]

Quick question is there ever a scenario where you configure your IDE correctly and it doesn’t work?

[lethal elbow]

1. They do
2. If I put isTrigger on my car it mess it up and when I put it on the object in goes through the ground (but I will check something)
3. They do

[edgy prism]

What if it’s a 2D project 👀

[willow scroll]

The same, but usually with 2D colliders and rigidbodies

[swift elbow]

Yes, the same way 2x2 doesn't equal 4 when done correctly 😅

"Correctly" implies that it will work, you have to be more specific

[edgy prism]

Ok thankyou, I’m in another discord for helping people with code someone asks a question (code is all black no colours, doesn’t autocomplete) I tell this person configure your IDE he says it doesn’t work and now someone is helping him manually change the colours in visual studio settings

[edgy prism]

Haha Thankyou I know I’m just being annoying

[edgy prism]

Already did 😭

[summer stump]

IsTrigger is only needed on one of the two objects
But it IS required for OnTriggerEnter (obviously, see the name)

[polar acorn]

Then you wouldn't be using the 3D collision methods

[lethal elbow]

Make sense, I will figure out something
Thanks for the help yall!

[polar acorn]

If neither one is a trigger then why are you using OnTriggerEnter? Use OnCollisionEnter if they're both solid

[summer stump]

Does the other object NEED a rigidbody? It won't fall through the ground if you don't have one

[willow scroll]

I wonder whether you should help them if you don't know it yourself?

Are they too shy to ask themselves? You're both going to end up wasting more time on this

[lethal elbow]

oh that may solve it

[summer stump]

Rigidbodies are for things that should be affected by physics in some way. If it's just a pickup or checkpoint or something, I see no reason for a rigidbody

[lethal elbow]

I was able to fix it!!

[lethal elbow]

i actually needed my rigibody since that object come from my spawn zone meaning they fall from the sky

[summer stump]

Ah, fair enough. One idea that comes to mind is to have the rigidbody for falling, then when it collides with the ground, delete the rigidbody and switch the collider to a trigger.

Or just use OnCollisionEnter for everything hahaha

Glad you fixed it

[lethal elbow]

I guess OnCollisionEnter would have solve it quicker hahaha I will keep it mind!
I appreaciate the help!

[smoky mauve]

is there any limit in string size in unity?

[tall delta]

no

[slender nymph]

That's kind of a terrifying question. What is the purpose of that question?

[smoky mauve]

im loading a 266 Kb csv into a string and its giving me trouble

[smoky mauve]

can i store it on a string list somehow?

[vast vessel]

does GetComponentsInChildren() also return a component in its array if its placed on the object calling this method?

[polar acorn]

https://docs.unity3d.com/ScriptReference/Component.GetComponentsInChildren.html

Gets references to all components of type T on the same GameObject as the component specified, and any child of the GameObject.

[rich adder]

yea

[vast vessel]

lets say the first line of a virtual method has return in it, and a method overriding it, has the base method, on its first line and some other operations next. will those operations also be aborted?

[polar acorn]

base.TakeDamage is just a function call

It behaves the same as if you did SomeOtherObject.TakeDamage() instead

it just specifically calls the version of the function from the parent class instead of this one

[mighty falcon]

what exactly is it asking me to do here

[rich adder]

static fields cannot be accessed on instances

since they live on the class itself

why is damage static in the first place

[mighty falcon]

good point

its not longer static

[hidden sleet]

with a raycast, is the layer you pass in one to ignore or one that it will only collide with?

[rich adder]

it can be both

[hidden sleet]

ah, how might I tell which way round I have it?

[rich adder]

if you add ~ you can Invert the mask (hit everything else but these)

[hidden sleet]

As i've got a layer for objects that can obstruct the view of something, and a player layer it needs to try and pickup on

given that, i think mine is just set to hit the layer I've given it

[young warren]

https://unity.huh.how/physics-queries/layer-masks
https://unity.huh.how/bitmasks

[hidden sleet]

just trying to troubleshoot why this isn't working as I'd like

Vector3 playerDirection = playerLocation.position - transform.position;
        Ray ray = new Ray(transform.position, playerDirection.normalized);

        if (Physics.Raycast(ray, out RaycastHit hit, playerDirection.magnitude, obstructionMask))
        {


            Debug.DrawLine(transform.position, hit.point);
            print("passed LOS");
            return true;


        }
        else
        {
            return false;
        }
``` I have it so when I enter this radius, it should perform a raycast to see if the source has LOS on the player, but it always returns false. Think I've missed something somewhere

[rich adder]

try Debug.DrawRay(transform.position, playerDirection.normalized * playerDirection.magnitude; instead

put it outside the if statement

[prime cobalt]

How could I find which enemy in a 3d space is closest to my crosshair in the center of the screen?

[rich adder]

Vector3.Distance + ScreenToWorldPoint

[prime cobalt]

Thanks!

[rich adder]

in 3d might be easier to use ScreenPointToRay or a plane, instead because of the prospective camera

https://unity.huh.how/screentoworldpoint

[prime cobalt]

Wouldn't ray also count the distance from the camera backwards as well as sideways/upwards?

[rich egret]

How to make a character jump while animating?

[rich adder]

a ray is nothing but an infinite line

[rich adder]

jump while animating wdym ?

[hidden sleet]

Seems to be drawing the ray twice as long as the actual distance

[prime cobalt]

I'll give rays a shot and if that fails I'll go with the screenpoint thing

[hidden sleet]

oh wait hol up

[rich adder]

ops yea should be playerDirection.normalized * playerDirection.magnitude

[rich egret]

Yes, for example I want to be able to jump while the running animation is running

[hidden sleet]

yeah fixed that, the ray is correctly projecting towards the player, but even if there are no obstructions it never behaves like it should when it has LOS

[rich egret]

https://gdl.space/jececoruru.cpp
This is the code

[rich adder]

use animation events

[hidden sleet]

So i can see the ray now, but the raycast always returns false

[rich adder]

which one is the item supposed to hit

[hidden sleet]

ray's supposed to come out from the sphere, be blocked by objects with the 'obstruction' layer, and if it hits the player without being blocked by said objects, does a thing

Unless I have things the wrong way round

[rich adder]

it cannot hit player if player is not inside the layermask filter

but it should hit obstructions, if you put them in the Layer on the gameobject itself ofc

[hidden sleet]

yeah that's what I've done, all I need is to return a boolean whether the player is obstructed or not

but at the moment it looks to always be saying it's obstructed, when it's not

[vast vessel]

can anyone tell me why i should not use null propagations on unity objects? i mean, they are way shorter then a if statement.

[rich adder]

it might be hitting itself

Debug.Log the hit.collider.name

[rich adder]

because unity overrides the null so in short it wont work
it deals with nulls in its own ways

[hidden sleet]

shouldn't be, the sphere only has the default layer, none of the player's layers have that layer on it either

[rich adder]

magic numbers as limits = index out of bounds

[finite dew]

I do
if (myunitything)
{myunitything.DoThing()}

I think it has something to do with how unity does garbage collection on destroyed objects or something, basically less error prone

[proven inlet]

Hi i need help bcs I lack for logic.
I want to make pattern for an enemy with pattern switching randomly( think of a bullet hell) but I dont have any idea how to do that

[astral basin]

wdym magic numbers

[rich adder]

particile system or somethign

[astral basin]

x = 1
i = 1 -> 4

[rich adder]

what is 4 what is 8 ?

[polar acorn]

Unity has a custom == null that also works on objects that have been destroyed but not cleaned up yet. The null propogation does not actually account for this, so an object that is "Unity null" would fail an obj == null check, but would pass an obj?.method() check and throw an unassigned reference exception

[astral basin]

8 is irrelevant its in a different section, it is the amount of audio sources though

[polar acorn]

Magic Numbers are numbers whose values you have to "just know" what they mean.

[proven inlet]

No its like attack, my enemy switch attack

[rich adder]

im just explaining to you what they are, it was rhetorical question

[astral basin]

still dont get it

[polar acorn]

If it's the amount of audio sources, why not just use the amount of audio sources as the variable instead of manually counting them and plugging in a number that becomes obsolete once you change the number of audio sources

[polar acorn]

How do you know 8 is the number of audio sources

[astral basin]

beacuse i have 8

[polar acorn]

Okay but how do you know

[rich adder]

then index max is 7

not 8

[astral basin]

ik

but it startrs at 0

[rich adder]

exactly

[astral basin]

oh

lmao

[polar acorn]

So don't use magic numbers. If you want to use the count of a list, use list.Count

[astral basin]

OH NO

mb i have 9 audio sources

[polar acorn]

don't just do it by hand and type it in

[astral basin]

its an array

[rich adder]

so .length

[vast vessel]

will this create one instance of a material, and then have all of my renderers use that same material instance like i want it to?

[rich adder]

the advice is still solide

[polar acorn]

So don't use magic numbers. If you want to use the length of an array, use array.Length

[astral basin]

like this?

[south sky]

Yo guys, what does serialise field mean?

[rich adder]

first time im seeing these weird crops 👏

[rich adder]

just makes private field show up in the inspector

serializing = storing/saving stuff in an organized way

[south sky]

Whats the benfit of having it private over public

[rich adder]

prevention of modification from outside of the class

encapsulation basically

guarding against yourself or collaborators from changing it in the future

[hidden sleet]

flipped them around, my logic was just backwards X/
I often get confused as to whether that parameter is for blocking or accepting hits

[south sky]

Security over simplicity

[polar acorn]

Yes. Those are pretty bog standard loops now. You won't hit an out of bounds exception with i with these no matter what audiosource and music are. You might still get one on volSliders though, you could probably do with a check to see if x is greater than the length of that array too

[astral basin]

its not i checked

[rich adder]

not "security" in the traditional sense

[astral basin]

x can be 0 and 1

the else statement is for the time its 1

it can only be 1

[rich adder]

ohhh so you were using Physics.Raycast bool wrong?

[polar acorn]

As long as you have it checked somewhere and are not just assuming it's correct, that's fine. It doesn't need to be in this method, it could be a check before calling this method

[hidden sleet]

believe so. As simple as that sounds :/

[rich adder]

ohhh that makes sense then lol

usually is

[astral basin]

oh so its nothing

i think

[polar acorn]

Organization. On a big project you're going to have an order of thousands of potential variables at your disposal at any given moment. If you make private the things that shouldn't ever be changed outside this class, you can add a field variable (to use between functions in this class for example) without increasing the overall complexity of the system

[lunar fern]

i posted this in the c# server and have still got no response so ill post it here:
so i have a glitch where the player starts "twitching" when you walk beside a block or just on a block thats not a plane. ive tried a bunch of things and now im getting brain bleed. i have no idea why this is happening (plus ive got a automatic parkour movement without implementing it!). ill leave the code and a vid of me showcasing it down below. thanks in advance

@polar acorn whenevr i use any of the sliders the error comes up yet the code works exactly as i intended

[polar acorn]

What error

[polar acorn]

What is line 89 of Button.cs

[polar acorn]

I would like to direct your attention to exactly the thing I said would happen

#💻┃code-beginner message

x is out of bounds of the array

So check

[astral basin]

i checked though, the script is attached only to those two sliders, in one, x=0, and the other x=1

[polar acorn]

And by "check" you mean "I looked at it and I assumed it was right" or "I explicitly put in an if condition that checks if this is correct so I know it has reached this place with valid values"

because the second one is what I said to do

and I have a feeling you're using it for the first

[rich adder]

btw shouldn't it be < instead of <=

[polar acorn]

Ah, also that

[astral basin]

what do you mean how can it be not 0 or 1 if i never defined it as something else

[polar acorn]

0 can still be out of bounds of an array with nothing in it

[modest dust]

i is out of bounds, it should be < instead of <=
x is probably alright (but I'd rather just make separate fields for these two sliders)

[astral basin]

i printed x infinitely and it said 0 or 1 aswell

[polar acorn]

Again, that's your fallible human brain, who knows if you've got a copy of this script with less vol sliders set?

[polar acorn]

While the loop condition is definitely wrong, this error is happening on x

[polar acorn]

How about, instead of going on a snipe hunt you just, you know, put in the if condition

[modest dust]

Oh, didn't notice that

[polar acorn]

Print the value of x and the length of the array

[astral basin]

both of the arrays?

since the error occurs on both lines

whenevr the loop is active

[polar acorn]

The only reason there wasn't an error on i is because it dies on the very first iteration of the loop

[polar acorn]

Once you've fixed the condition like navarone and caesar pointed out, i cannot be out of the bounds of audiosource or music. x, however, can be outside of the bounds of volSliders

[south sky]

Those crops man

[polar acorn]

Because nothing in your code is preventing you from passing in 4 or -12 or 525600, and nothing in your code is checking if volSlider has anything in it at all

[astral basin]

i dont get it

what do u want me to do

[polar acorn]

if (x < volSlider.Length)

And maybe an else statement with a log that prints x and the length of volSlider so you can see what those numbers are when it goes awry

[astral basin]

like so?

[polar acorn]

Sure, but putting it around the function call is probably fine, that way you don't need to add it twice to have it around both conditions

[modest dust]

Around, or an early return

To avoid more nesting

[astral basin]

ran it, console only prints the error

the else statement isnt printing anything

[lunar fern]

can someone help me because my player movement script somehow got Wal climbing without me even needing to code it? like i stick to walls and stuff

[astral basin]

and it lets the for loop run

[summer stump]

Stop taking screenshots like that
You can just put the code here too

Like so

[polar acorn]

Where did you end up putting the if statement, and what line throws the error

[modest dust]

You still didn't fix your for loop

< instead of <=

[astral basin]

wdym you told me to change it to length

ok let me do that

[polar acorn]

No, they told you to use <

Multiple people, in fact

Length is fine, that's not the problem

[lunar fern]

please ive tried to fix it for a while now and its still not fixed

[lunar fern]

anyone please

[rich adder]

be patient bro

[rapid crescent]

send your code lets have a look

[astral basin]

wait wtf did i write

[rich adder]

also you have no provided code

[polar acorn]

1. That only checks one condition
2. your else has no braces so it will just always print volSliders.Length

Wrap the call to freqVolume in the condition

i cant its called through a slider drag

[polar acorn]

so x is the value from the slider?

[astral basin]

no

[polar acorn]

then where does the parameter come from

[astral basin]

x is the int in freqvolume

[lunar fern]

basecly it stiks to wals and i dont know why

[astral basin]

its either 1 or 0

[lunar fern]

ill send i vid

[polar acorn]

okay and where have you told the code that

what calls this function

[rapid crescent]

please send a video of the issue as well

[astral basin]

in the inspector i set x to 1 on slider1 and to 0 on slider2

[astral basin]

onvaluechanged

[polar acorn]

Okay, I think I get what you're doing now. I didn't know what you meant because this is an absolutely terrible, convoluted system for implementing multiple sliders

Do you want to fix this one or do you want to do it correctly?

[lunar fern]

it took a while to upload but there

[astral basin]

thanks

[astral basin]

lets do it correctly

[polar acorn]

Make two functions. Both take a float parameter. One loops over audiosource and sets the volumes to that parameter. One loops over music and sets the volumes to that parameter. Call that function from the slider OnValueChanged. It will pass in the float from the slider and you no longer need to have an array of sliders

[smoky mauve]

    public List<Carrera> RandomRacesCreator()
    {
        print(dias.Count);
        List<Dia> RandomDays = dias;
        Shuffle(RandomDays);

        float reductionPercentage = UnityEngine.Random.Range(0.3f, 0.5f);

        // Calculate the number of elements to remove
        int elementsToRemove = Mathf.FloorToInt(RandomDays.Count * reductionPercentage);

        // Remove elements randomly
        for (int i = 0; i < elementsToRemove; i++)
        {
            int randomIndex = UnityEngine.Random.Range(0, RandomDays.Count);
            RandomDays.RemoveAt(randomIndex);
        }
        List<Carrera> carrerasa = new List<Carrera>();
        foreach (Dia dia in RandomDays)
        {
            foreach (Carrera c in dia.Carreras)
            {
                carrerasa.Add(c); 
            }
        }
        return carrerasa;
        
    }

Why is the script removing the variables form dias?

if i call this function various times it eliminates the Dia from dias and not form RandomDays

shuffle is a custom function that shuffles the list

[polar acorn]

RandomDays and dias are the same list

If you want a copy of dias, do List<Dia> RandomDays = new List<Dia>(dias);

[smoky mauve]

oh

[astral basin]

oh yeah the arrays were to save 1 line of code lmao

but if i have 2 functions and 2 sliders i dont even need the float do i

[polar acorn]

The float parameter is the value of the slider

[astral basin]

i can just volume = slider.volume

[polar acorn]

You don't even need to reference the slider

Just use a parameter

[astral basin]

ohhhh

[polar acorn]

the slider passes its value to the function

[astral basin]

and then volume = x?

wait what

idk what im doing

[rapid crescent]

cant seem to see the issue

[polar acorn]

Yes. Although tbh you can probably just use a foreach instead of an indexed for loop

[lunar fern]

you know what ill just ignore it. try and find a better alternitive for my scripting

[astral basin]

my "how to build a game like fortnite" course that i bought 5 years ago didnt include foreach

[polar acorn]

Then it was a dogshit course you shouldn't have spent money on when !learn exists

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

[astral basin]

well whats done is done

[astral basin]

anyway what did i do wrong cuz what i wrote doesnt reference in any way the slider volume amount

[polar acorn]

You can still do Unity Learn

[polar acorn]

The parameter

[astral basin]

true

[astral basin]

but no one told x to be equal to slider.volume

[polar acorn]

The OnValueChanged passes the value

[astral basin]

ohhh

[polar acorn]

As long as you actually picked the dynamic function

[astral basin]

my course didnt have sliders either

[polar acorn]

and not entered a value in the box

[astral basin]

ok let me run it

[polar acorn]

Show a screenshot of your slider's inspector

is your slider set to ints?

[polar acorn]

Use the dynamic function, not the one that has you enter in a value manually

[astral basin]

what can i change to dynamic

[polar acorn]

When you pick the function

pick the one from the "dynamic" section

[astral basin]

ohh

[polar acorn]

Do that on both

[astral basin]

alr

YES

THANK YOU SO MUCH

[polar acorn]

Now consider doing !learn to catch up on the things you missed

[south sky]

Guys from this code I only want the enemy to track the x position of the player, how would I do this?

[rich adder]

position.x?

u wont be able to use it in MoveTowards

make a new v3

Vector3 targetPos = transform.position;
targetPos.x = player.transform.position.x```

[south sky]

Thanks navarone but this would make the enemy teleport to the players x position, how about just slowing moving there?

[summer stump]

Not a code question
And don't crosspost

[rich adder]

it doesnt ?
did you not put that inside MoveTowards targetPos ?

[south sky]

Oh

Mbmb

Yo @rich adder you gonna make more yt vids?

[rich adder]

Did it work?
And I usually make them when I can or feeling inspired, been very busy lately .
I'm working on a site though it will have many written tutorials

[south sky]

Yep

[south sky]

I feel like vid tutos would attract a bigger audience though

Especially younger

Unless you dont care about them kids lol

[rich adder]

I just enjoy making videos, I kinda hate using a microphone xD

there are more youtubers with more oomf personality for videos haha

Loll i get ya

[frosty river]

Hey all I'm really stuck on this muzzle effect:
the cone of light only goes backward

[swift elbow]

Looks like you're using a point light or your cone is manually placed incorrectly

Not much more I can discern off of such little info tho

[frosty river]

I'm u sing particle system for the muzzle flash effect

it's from a free asset pack

[swift elbow]

Show the outline of the cone

Like in your scene view

[frosty river]

how can I get it to show the outline of the cone?

[swift elbow]

By selecting your light gameObj

[frosty river]

I have the muzzle effect selected

[swift elbow]

You need to select the light, the muzzle is different

[frosty river]

how can I select the light?

i don't see it on the hierarchy

I just have MuzzleFlashEffect on the hierarchy

[swift elbow]

Select whichever gameObj is giving off the light and turn gizmos on...

[frosty river]

sorry not sure what you mean by turn gizmos on

there is a light module for the particle system component

[swift elbow]

Ok select it

Can you see a cone in your scene view?

One that reflects how the light is showing?

[frosty river]

expanding the Lights module does nothing

as far as scene view

[hot palm]

Can I draw a ray (debug), using a Ray as input?

[swift elbow]

No that's not the right thing

Press on the gameObj in the light area

[frosty river]

"ParticlesLight"

[swift elbow]

"ParticlesLight (Light)"

[frosty river]

yea

I have it open in Project tab and inspector

(ParticlesLight)

[hot palm]

Ah this should work

[swift elbow]

Now send an ss of it selected and showing in the scene view

[frosty river]

I don't know how to make it show in scene view

[swift elbow]

When you select it, it should be highlighted in your hierarchy

After selecting, press f to focus

[frosty river]

it's not in the hierarchy though

[swift elbow]

So that's not the right object

Use the search bar and search for lights

And find which one is the muzzle flash light

[frosty river]

nothing shows, the only light in my hierarchy is the directional light of the sun

but the ParticlesLight are definitely the cause of the backwards cone

[rocky canyon]

flip it

[swift elbow]

Rotate it

[hot palm]

Yup

[frosty river]

ok so rotate the ParticlesLight

[swift elbow]

Yes, then you will know if that is really what's giving off the light

[swift elbow]

Wait what

No, rotate the particle effect

[frosty river]

Rotating the particle effect has no effect

[rocky canyon]

yea,, u need to sim it in local space no?

[frosty river]

i think its only effecting the orange square part here:

[swift elbow]

So there is a gameObj in your scene that has a light component

Find it

[frosty river]

that light in the back

on the player

is definitely ParticlesLight

because when I uncheck Lights on the effect it disappears

[swift elbow]

Show the inspector for it

[frosty river]

inspector for ParticlesLight?

[swift elbow]

Yes

[rocky canyon]

if ur rotating ur particle and nothing is noticeable.. it leads me to believe its simulating in world space

instead of local space

[frosty river]

ok, here it is. note that it's a prefab, not in hierarchy

[swift elbow]

Show the one in the hierarchy

[frosty river]

the Effect?

[ruby python]

Evenin' all. I've got myself a couple of issues I can't seem to figure out with my enemy spawner.

Video to demonstrate the current working for context.

https://streamable.com/ud8k8j

Wave Spawner code with a comment at the top explaining one issue.

https://pastebin.com/vaMvd2iz

Basically I have a wave spawner where I'm trying to keep track of the enemy count per 'wave' when the enemies 'hit' their position in the grid formation the count goes up by 1 (if they get destroyed, the count goes down) and at the end of the wave, if the enemy count is 0, then a power up will get dropped. Now the keeping track of how many enemies there are works fine.

https://pastebin.com/yYdFwh6j
This is how I'm keeping track of the enemy numbers.

The first issue is I can't figure out where to 'reset' the enemy count to 0 as the Waves 'overlap' each other in terms of spawn time, so if the next wave starts to spawn and the count gets reset to 0, if I shoot one of the previous waves enemies, the count goes into negative numbers.

The enemies are governed by a State Machine

Enemy Code.
https://pastebin.com/agAjHcn2

Apologies if that's a lot, but this is driving me up the wall.

And please excuse any random un-needed 'using's for some reason VS keeps randomly adding them.

So, basically, any ideas where I should put my reset to 0 line? 😕

[swift elbow]

No, select particleslight in your hierarchy

[frosty river]

it's not in hierarchy

as you can see only Directional Light (the sun) is there

[swift elbow]

Press the box next to the search bar and search by component

[frosty river]

the box to the right of the search bar?

[swift elbow]

Yes, that's what I just said

[sharp wyvern]

it sounds like you need an array/list of enemyCounters, one per wave, OR each enemy needs to know which wave it is a part of, and the state machine would need to know which wave the current wave is (so that it only decrements the counter when the enemy's wave number matches the current wave number).

[swift elbow]

Ok now show the inspector

For that gameObj

[swift elbow]

You meant the prefab is what you have in your scene 🤦‍♂️

Unpack it and mess around with the values

Or don't un pack it

Up to you

[tall delta]

do you actually need to know the count, or do you just want to spawn a powerup ever n'th kill?

[swift elbow]

Also press e and rotate the gameObj

[ruby python]

I need to know the count. Idea is if the player destroys every ship in a wave, a power up drops.

[frosty river]

rotate the prefab, ParticlesLight?

[swift elbow]

Yes, you don't have to ask for permission for everything

[frosty river]

rotating the prefab has no effect

[swift elbow]

Press f and focus it in your scene

Where is it?

[frosty river]

it's not in the scene

[swift elbow]

🤦‍♂️

[swift elbow]

Ofc rotating a prefab is gonna have no effect if it's not in your scene

[frosty river]

right

[sharp wyvern]

that sounds like you'l need a list of enemyCounters... one for each wave. Assuming: you destory all of wave 1, after wave 2 has started. The enemies will still need to know which wave they are a part of, so it can decrement the appropriate counter in the list

[swift elbow]

Rotate whatever obj is giving off the light

Idk how you don't know what it is

[ruby python]

Right okay. I'll give that a go tomorrow, brain is a bit cabbaged for tonight. lol.

Thank you 🙂

[frosty river]

i believe the muzzleflasheffect is what's giving off the light. rotating it has no effect

[hot palm]

Best notification I got today AAAAAAA

[willow scroll]

Hello, does someone know why accessing Image.material doesn't create an instance of it?

renderQueue = image.material.renderQueue;

Accessing TMP_Text's fontMaterial does though

renderQueue = text.fontMaterial.renderQueue;

[rocky canyon]

hallelujah 🙏

[hot palm]

From one problem into the next one tho

[rocky canyon]

when u access the material ur accessing the property of the shared material, when u access the text ur accessing the material instance specicially for the text component.

u probably need to create a copy of the image material and queue that

[tender stag]

how can i check if an animator has a trigger?

[willow scroll]

Oh, I haven't noticed there is no sharedMaterial on the image

[tender stag]

how can i check if an animator has a trigger?
like if(animator.TriggerExists("Shoot"))

[rocky canyon]

ya, not sure exactly how it works on image.. but maybe try making the copy of it instead

just an idea

[willow scroll]

That's a great idea, appreciate your help

[rocky canyon]

i know when i want to change the material of a renderer i have to do the same..
create a copy.. modify the copy.. assign it back to the renderer

[rocky canyon]

var params = animator.parameters;

foreach (var param in params)
{
    if (param.type == AnimatorControllerParameterType.Trigger && param.name == triggerName)
    {
        return true;
    }
}```

[hot palm]

My ray is doing this, but still logs Hover regardless of where I am aiming, but only when I am clicking the mouse button?

(The Function Hover just Logs Hover!)

Anybody got an idea why?

[tender stag]

so this is fine?

[rocky canyon]

ive never used the exact syntax or hunted for triggers i didnt know where there

soo. you can test for me 😆

[rocky canyon]

no.. it shouldn't be logging only when you're clicking the mouse button

[hot palm]

Yeah that's weird

[rocky canyon]

its in fixedupdate.. w/o being in any kind of input conditional

unless u have multiple scripts running.. and (1) is

[hot palm]

I have this, but I don't use mousePos anywhere

[rocky canyon]

then why u have this?

[hot palm]

Before I did the LookAt - POV, I did the MaincameraToScreenPoint. But that didn't work, so I tried it without using an input action (potentially wrong)

I am very confused bcs it doesn't seem logical for once

[tender stag]

seems to work

thanks

[rocky canyon]

👍 ur very welcome

may not be the most performant to search thru all the params of the animator tho

[tender stag]

i'll prob end up having a bool

[rocky canyon]

cool, just letting u know in case u get performance issues later down the road

you'll know what to look for

[untold raptor]

is there a decent way of rendering 3D models onto a canvas? or if not possible whats the next best workaround

[rocky canyon]

as long as it doesnt have 100s of params u should be fine

[tender stag]

i only have 3

[rocky canyon]

does it have to be on the canvas or can it just be behind hte canvas?

u could have the camera w/ the canvas render just the model

w/ the UI on top (or around it)

[untold raptor]

its gonna show the active tool so im not sure

[rocky canyon]

if you wnat it to be part of the canvas like a 2D image.. you can use a 2nd Camera.. and a RenderTexture

ur Image component would hold the render texture.. and it would be rendering w/e the camera is showing..

ie: focused on ur 3d model

[untold raptor]

i see

[hot palm]

Any ideas? 🥲

[rocky canyon]

where is ur Hover() function?

can you show it? !code

[leaden lotus]

Good evening, im struggling with a code where my code works, half of the time. So basicly my code consists of:

public bool hit;
Vector2 movement = new Vector2(horizontal * moveSpeed, rb.velocity.y);

hit = Input.GetMouseButton(0);
if (hit);
{
terrainGenerator.RemoveTile(mousePos.x, mousePos.y);
}
anim.SetBool("hit", hit);

and it will not allow me to break all the blocks on the map. Blocks are being placed like:

public void PlaceTile(Sprite tileSprite, float x, float y, bool backgroundElement)
{
    GameObject newTile = new GameObject();

    newTile.transform.parent = this.transform;
    newTile.AddComponent<SpriteRenderer>();
    newTile.GetComponent<SpriteRenderer>().sprite = tileSprite;
    newTile.name = tileSprite.name;
    newTile.transform.position = new Vector2(x + 0.5f, y + 0.5f);

    worldTiles.Add(newTile.transform.position - (Vector3.one * 0.5f));
    worldTileObjects.Add(newTile);
   } 

and are abled to be deleted by:

public void RemoveTile(int x, int y)
{
    if (worldTiles.Contains(new Vector2Int(x, y)))
    { 
        Destroy(worldTileObjects[worldTiles.IndexOf(new Vector2(x, y))]);
    }
}

and for some reason i dont understand why it will allow me to break some of the blocks on the map, but it wont allow me to break all of them. This is totally random so idk whats going on. If anyone could help me?

can u change ur debug to include this? then in ur Hover() method.. u can
hit.collider.gameObject.GetComponent<InteractableObject>().Hover(this);

u can see what script is calling it.. if it is indeed ur only script it would be obv but im not sure..

[hot palm]

Yes Ill try

[rocky canyon]

is there an interactable object blocking the raycast?

idk why it would be being called all the time

especially when ur pressing left click..

[hot palm]

No for testing I tagged evrything as untagged an only the object as interactable

[verbal meteor]

Hi, how can i save this in PlayerPrefs?

[rocky canyon]

ud just need to save the musicSource.mute bool

[hot palm]

Okay interestingly I get no logs now

[rocky canyon]

and when u read from it.. do the function

[hot palm]

ah I know whay

[rocky canyon]

👀

[hot palm]

forgot to updte this

[rocky canyon]

ohhh u have events going too?

[hot palm]

One step closer

[rocky canyon]

well its not passing in any object

so its like running by it-self?

[rocky canyon]

#💻┃code-beginner message

did u add this part?

yea.. weird

it should show u the script/object that ran that function

[hot palm]

I can assume my code is not working, but me left clicking starts this event somehow

[rocky canyon]

but its saying null

ahh yea.. the event part i wasnt even aware of

thats probably linked to ur mouse click

alright.. u can change it back how u had it.. that didn't reveal any use-ful information as i thought it would

[hot palm]

Well I now know that event stuff isnt really working perfectly

[verbal meteor]

and the SetActive?

[rocky canyon]

ya, silver lining i guess

[rocky canyon]

no, ud just do that after u read the bool..

like when ur loading

-> set it[yourgameobjectsyouneedactive] active or inactive.. to match```

playerprefs should contain simple data..

1s and 0s

strings and such

all u need to know is if it is muted..

and then if it is.. ur loading logic would handle what changes in the game

[hot palm]

PlayerPrefs.SetInt("Music", 0);
bool music = PlayerPrefs.GetInt("Music") == 0 ? false : true;

Like this

[untold raptor]

thanks this worked a charm

[hot palm]

private void Interact(InputAction.CallbackContext context)
{
    interactEvent.Invoke();
}

I did this for the function, so ofc no script called it...

[dusk musk]

Hi folks! Can somebody advise me on how to fix my script for successfully printing my player name? My current script is:

    public static string playerNameInput;

    public void ReadPlayerName(string playerNameString)
    {
        playerNameInput = playerNameString;
        Debug.Log("Player name = " + playerNameString);
    }

I believe the issue comes from the section circled in red on my screenshot. There shouldn't be a field to type something, right?

Thank you!

[hot palm]

Turns out why it was loggin this, now I just need to find out how to get the raycast thin working

[rocky canyon]

i think you're gonna need someone more advanced than me to figure out that issue, sorry 😦

[hot palm]

Maybe I am using a bad approach

No I understand it now it's fine

[rocky canyon]

ya, i would just retry

do it something simple..

i tend to isolate things until i get them working/fully understand them

[hot palm]

Yeah

[rocky canyon]

may help you too.. to maybe make a new scene w/ nothing in it..

and just work on that 1 script.. maybe a simple cube or 2

[hot palm]

Well I did just that

[rocky canyon]

ya, even simpler..

forget about the capsule/controller and everything else..

[verbal meteor]

only this or? sorry i´m beginner

[hot palm]

No you would safe it, whenever you change it

So OnMusic has the PlayerPrefs.SetInt("Music", 1); (1 is for true)

and OffMusic has PlayerPrefs.SetInt("Music", 0);

[rocky canyon]

// Read your data
bool isMuted = PlayerPrefs.GetInt(MuteKey, 0) == 1;

// Now apply your data to the game world
musicOn.SetActive(!isMuted);
musicOff.SetActive(isMuted);```

[hot palm]

Then this

bool musicOn;
private void OnEnable()
{
  bool musicOn = PlayerPrefs.GetInt("Music") == 0 ? false : true;
}

you wouldn't need musicOff, as musicOn being false means the music is off

[rocky canyon]

yup. just 1 bool..

isMusicOn and isMusicOff is the same property

altho i know why u have 2 gameobjects..

1 for like a Microphone.. and 1 for a Microphone with a slash thru it

but u dont need that extra stuff for the playerpref key

just do that in ur logic after u read the key

[hot palm]

I have 2. One static instance one the player and the other one on any object that is interactable. I use the event to apply the script to the interactible to have variable stuff that happen when I interact

[rocky canyon]

same for like levels.. if ur on level 2..u just read that 1 value.. and then ur gamemanager or w/e would set up everything else.. that level2 needs

[rocky canyon]

sounds a bit overly complicated imo

[slender nymph]

i know this is just an example, but the person the example is actually for clearly just copies code blindly so you should probably fix that issue where the GetInt call is assigning to a local variable entirely unrelated to the musicOn field

[rocky canyon]

how beginner are you?

[hot palm]

2 years into unity

[verbal meteor]

i dont know, I do not understand PlayerPrefs :/

[hot palm]

Know nothing of netcode but a bit about stuff going on.

[rocky canyon]

ahh okay.. about the same as me.. have you never worked with raycasts before?

[hot palm]

Not really that's the problem I am at right now

I have problems with detecting collision with raycasts

All the stuff I tried didnt work

[rocky canyon]

oh yea, me neither.. im 3 years into Unity.. i know my way around raycasts for sure.. but i havent touched netcode yet

[hot palm]

Can I call OnTriggerStay on the script doing a raycast and make the interactable a trigger?

Do I put OnTriggerStay on the intersecting object or the one with the trigger collider?

[rich adder]

why use triggers event if ur using raycasts

[rocky canyon]

// Check if the left mouse button is pressed
if (Input.GetMouseButtonDown(0))
{
    // Perform a raycast from the raycastStart position in the forward direction
    RaycastHit hit; // Store information about the object hit
    if (Physics.Raycast(raycastStart.position, raycastStart.forward, out hit, distance, shootableLayer))
    {
        // Log the name of the object hit
        Debug.Log("We hit: " + hit.transform.name);

        // we also have the *hit* variable we can check against for components / tags
    }
}```

heres my basic raycast script that i recycle..

pretty basic.. and has everything ud need as a beginner.. uses a layermask... and has an out variable

[hot palm]

Yeah but that doesn't work somehow

[hot palm]

What I want to do is

Have the object know when I could interact with it and the object listens to my input and does the event when specified input is done.

[verbal meteor]

what is MuteKey?

[rocky canyon]

a string

the name of ur playerpref key

[hot palm]

string muteKey = "Music";

In this case

[rocky canyon]

like this?

private const string MuteKey = "IsMusicMuted";``` i actually used a cosntant in my example code

but same thing..

[hot palm]

Just so you use variables and it always works when changing the variable name

[hot palm]

Yeah this is smart

private void FixedUpdate()
{
    Vector3 raycastDirection = (_LookAt.position - _POV.position).normalized;

    RaycastHit hit;

    Ray ray = new(_POV.position, raycastDirection * interactRange);

    if (Physics.Raycast(ray, out hit, interactRange, LayerMask.GetMask("Interactable")))
    {
        if (hit.collider != null)
        {
            if (hit.collider.gameObject.CompareTag("Interactable"))
            {
                hit.collider.gameObject.GetComponent<InteractableObject>().Hover(this);
            }
        }
    }

    Debug.DrawRay(_POV.position, raycastDirection * interactRange, Color.red, 1.0f / 60.0f);
}

This should work, no?

[rich adder]

wrong

ray don't have a range

[hot palm]

Oh good to know

[rich adder]

they are infinite line from 1 point toward direction

[verbal meteor]

I know is bad but i don't know what do next or :///

[rich adder]

wrong you don't store local variable

[swift crag]

youdo have interactRange as part of the raycast, though, so it should work out

[hot palm]

Put the GetInt line in the enable function like this

private void OnEnable()
{
  bool musicOn = PlayerPrefs.GetInt(MuteKey) == 0 ? false : true;
}

Because it will ask for the value you want, when you start it

[slender nymph]

that's assigning to a local variable whose scope is entirely within that method

[hot palm]

Also you do this

private const string MuteKey = "IsMusicMuted";

Above outside the function

[mild void]

Hey Guys, Can anyone have help to why the transform position of 2 prefabs is the same, but their position in the scene is different? Thanks (:

[slender nymph]

this sounds like not a code question. and by the vague wording of this, i'd assume you are actually referring to the tool handle position. make sure your tool handle is set to pivot rather than center

[verbal meteor]

what I got lost

[hot palm]

The transform origin of a child is its parent. So if you have a parent and a child, the child has to be 0, 0, 0 to be on the same position

[hot palm]

Just a sec

[mild void]

Im sorry to be slow, but how do i change that?

[slender nymph]

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

[hot palm]

private AudioSource musicSource;

private const string MuteKey = "MuteMusic";

private bool isMuted = false;

private void Start()
{
    isMuted = PlayerPrefs.GetInt(MuteKey) != 0;
    musicSource.mute = isMuted;
}

private void ToggleMusic(bool value)
{
    musicSource.mute = !value; // Calling this function with true will mute the music

    int num = value ? 0 : 1; // Int is 0 when not muted, 1 when muted
    PlayerPrefs.SetInt(MuteKey, num);
}

[mild void]

sorry i dont know the terminology quite yet, thanks for the help

[hot palm]

Is it (bool) ? when true : when false; or the other way around?

[rocky canyon]

condition ? true : false

[hot palm]

Okay

[slender nymph]

PlayerPrefs.GetInt(MuteKey) == 0 ? false : true;
can just be PlayerPrefs.GetInt(MuteKey) != 0;
also what's the point in storing that in a field if you are just not going to use that field ever

[hot palm]

I edited it now it makes sense

Also that's good to know

[polar acorn]

if ? then : else

[hot palm]

Looking this up is difficult xD

[polar acorn]

It's called a "Ternary Operator"

that'll help you find it online

[hot palm]

ohh thx

[hot palm]

Changed it a bit still doesn't work

Lemme trouble shoot

[queen adder]

can i get iframe to add my unity webgl game to my website

[rich adder]

just copy whatever code unity gives you inside the index.html

[queen adder]

i dont think that will work

[rich adder]

ofc it works

[slender nymph]

have you tried it?

also #🌐┃web

[queen adder]

i need an iframe. iframe is a little box you can play it in.
copying all the code will just mess the entire thing up

[rich adder]

ok, i know what an iframe is

[queen adder]

told you

when I pressed yes it didnt work.
i am gonna scavenge the code for an i frame

[slender nymph]

#🌐┃web

you also don't need an iframe. you just need to embed the game onto the page literally the same way that the index.html file does for the built game

[verbal meteor]

    private bool isMuted = false;

    private void Start()
    {
        isMuted = PlayerPrefs.GetInt(MuteKey) != 0;
        musicSource.mute = isMuted;
    }

    private void ToggleMusic(bool value)
    {
        musicSource.mute = !value; // Calling this function with true will mute the music

        int num = value ? 0 : 1; // Int is 0 when not muted, 1 when muted
        PlayerPrefs.SetInt(MuteKey, num);
    }

    public void OnMusic()
    {
        musicSource.mute = false;

        PlayerPrefs.SetInt("MuteMusic", 0);
        bool music = PlayerPrefs.GetInt("MuteMusic") == 0 ? false : true;

        bool isMuted = PlayerPrefs.GetInt(MuteKey, 0) == 1;

        
        musicOff.SetActive(isMuted);

        //musicOn.SetActive(true);
        //musicOff.SetActive(false);
    }

    public void OffMusic()
    {
        musicSource.mute = true;

       
        musicOn.SetActive(!isMuted);

        //musicOn.SetActive(false);
        //musicOff.SetActive(true);
    }```

like this?

[hot palm]

You can delete Off and On music

I don't know what you want to achieve with

//musicOn.SetActive(true);
//musicOff.SetActive(false);

but you can add it if you need it

[eternal needle]

Didnt see the original issue but how come you set and try to read it instantly?

[hot palm]

Now just call ToggleMusic(false) somwhere to mute it

[slender nymph]

because they have copied code from multiple different examples blindly without actually understanding any of what is happening

[hot palm]

We should probably check it, true.

if (PlayerPrefs.GetInt(MuteKey) != null)
{
  isMuted = PlayerPrefs.GetInt(MuteKey) != 0;
  musicSource.mute = isMuted;
}```

[slender nymph]

if (PlayerPrefs.GetInt(MuteKey) != null)
is not valid

an integer cannot be null

[verbal meteor]

this?

[hot palm]

How di I check for it existing?

[slender nymph]

and that is also entirely unrelated to what bawsi was asking

[hot palm]

Thought he meant reading it instantly = in start

[hot palm]

Yes

[rich adder]

int?
/jk 😛

[slender nymph]

no, it was set on one line then get on the next several lines

[hot palm]

Well OnMusic and OffMusic are italian food at this point (Spaghetti), so they can go

You should probably rename ToggleMusic to MuteMusic for better readability

(Mark it, press F2 and rename it there, press enter) That changes the name everywhere

Sorry for messing stuff up. I'm working on a game jam simultaneously and I really need to get stuff done haah

[verbal meteor]

i'm sorry to bother you

[hot palm]

Last thing I realize it you should change it to

musicSource.Mute = value;

if you rename it to mute music, aswell as swap the line to

int num = value ? 1 : 0;

[verbal meteor]

can i tell you what i need to do?

[hot palm]

You can always ask. In the case I don't answer some one else will surely

[verbal meteor]

I need if it´s mute (this button)

like this

i change the scene and come back

[hot palm]

I see

Then add the code with the set active

[verbal meteor]

to remain mute

[hot palm]

MuteLogo.SetActive(value);
NotMuteLogo.SetActive(!value);

[hot palm]

It should, if it's not staying the same and you followed everything you will need someone who understands playerprefs. I don't like using them. I rather use actual data saving like json

[verbal meteor]

okay thank you

[verbal meteor]

where should I put it?

[hot palm]

How tf does the object change transform

[hot palm]

at the end of MuteMusic

Or how you named it

[hot palm]

private void FixedUpdate()
{
    Vector3 raycastDirection = (_LookAt.position - _POV.position).normalized;

    RaycastHit hit;

    if (Physics.Raycast(_POV.position, raycastDirection, out hit, interactRange /*, LayerMask.GetMask("Interactable"*/))
    {
        if (hit.collider != null)
        {
            Debug.LogWarning("Intersecting Raycast object " +hit.collider.gameObject.name + " at " + hit.collider.gameObject.transform.position + "!");

            if (hit.collider.gameObject.CompareTag("Interactable"))
            {
                hit.collider.gameObject.GetComponent<InteractableObject>().Hover(this);
            }
        }
    }

    //Debug.DrawLine(_POV.position, _LookAt.position, Color.red, 1.0f / 60.0f);

    Debug.DrawRay(_POV.position, raycastDirection * interactRange);
}

[slender nymph]

it looks like your raycast is hitting the cube object on the player

[hot palm]

oh my

you are completely right

face palm moment

Sometimes we don't see the things directly in front of our eyes

I had removed the capsule collider but not the box

[slender nymph]

why did you remove any colliders? you should be using a layermask with your raycast to ensure it only detects colliders you want it to

[hot palm]

I usually have that, but as you see I commented it out for troubleshooting

Also I remove all colliders from my visual stuff, as I don't need them messing with the controller

Is there a simple way to debug something every second instead of every frame?

[frosty hound]

You'll have to make a timer

[hot palm]

I see

alternative would be an IEnumerator with wait for seconds and then calling stopcoroutine at some point, would that work?

[frosty hound]

Alternatively, you could use the Invoke call and set it to 1 second to call a debug function

https://docs.unity3d.com/ScriptReference/MonoBehaviour.InvokeRepeating.html

[hot palm]

And if a condition is true recursively call it huh?

[frosty hound]

Yes that would work if there was a need to stop it

[hot palm]

Yeah I kow of them, but I read those shouldn't be used

[eternal needle]

Well you're just debugging, it doesnt matter if you use them

[frosty hound]

This is for debugging, so you can be as messy as you want.

[hot palm]

I see

So I am educated correctly, that invoking is a bad thing? xD

[frosty hound]

It's just unnecessary if you've organized your code correctly

[hot palm]

I guess coroutines do everything you would need so no need for invoking?

Btw I'm trimmed to used private functions and parameters as often as possible, why's that? Hacking/Cheating?

[frosty hound]

You can't prevent hacking or cheating by making things private

It's purely for code organization, and preventing accidental changes by the developers.

This really only matters when things get large or with multiple developers working together.

[hot palm]

I see, good to know. Thanks for the information

[austere hedge]

What is the syntax for the 'i' at the end of Coin? I have pickups that are called Coin1, Coin2, etc.

I vaguely remember it looking something like $"Coin"[i] as well but it's still not right.

[hot palm]

$"{Coin[i]}"

[rich adder]

why would coin ever have [] in its name

[hot palm]

I think

[rich adder]

still wrong

[slender nymph]

$"Coin{i}"
https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/tokens/interpolated

[rich adder]

this will print the object

[hot palm]

Oh mb didn't understand what was asked

I really should focus on one thing at a time

My compare tag seems broken

[atomic yew]

Hello everyone. In Unity, my particle effect covers my item as I want, but when running on Android, my particle effect does not cover my item. What could be the reason for this? Does anyone have information?

[slender nymph]

also basing your logic on gameobject names is a bad idea. check for a tag or component, not the object's name

[austere hedge]

Thank you I didn't know what this was called.

[austere hedge]

I thought about checking by tag, but the object is not in the scene yet. I thought I could only look for objects by tag if they are in the scene.

[hot palm]

It almost works. I get a reference to the Interactable GameObject. It just doesn't seem to accept the tag.

[slender nymph]

i didn't mean use FindGameObjectWithTag or whatever

i just meant to not base your logic on the name of an object. like when you collide with an object or whatever don't check its name, check its tag or for a specific component

[hot palm]

This is how I get target

[slender nymph]

print some useful information rather than useless numbers. you can print what was hit and its tag

[hot palm]

Well I do that, but only once for every new object

I know I hit the cube

And the 1 runs

just the 2 not

meaning something is wrong with _Target.CompareTag

[slender nymph]

because you've hit something that you are not expecting to have hit

nothing is wrong with CompareTag

[hot palm]

Wait is it checking the parent tag? ughh

It is

[slender nymph]

because that was the object that was hit by the raycast

[hot palm]

It is checking cube tag, not the object the collider is on

The collider is on the Interactable object

[slender nymph]

Cube also has a collider

[hot palm]

👀

Makes ense why I get a nullpointer

Gosh I hate it

It's the simple small things

thx for enduring my stupidity @slender nymph 💌

[carmine sierra]

what is that function which can be used to detect collisions for non-trigger colliders

does it run as soon as the collider is touched

[hot palm]

OnCollisionEnter?

[carmine sierra]

yeah thanks

[hot palm]

There is also OnCollisionStay which is called every frame they intersect, not just once

[carmine sierra]

thanks

Any idea the best way to make a simple 2D destruction

in terms of visuals

of a rectangle

[hot palm]

particle system I guess

Dani said it's good

xD

Or shader stuff. I'm not into shaders tho

yet

[carmine sierra]

thanks ill try it

[hot palm]

What happens to Debug stuff when leaving it in a build?

[ripe shard]

Depends on what log level/behaviour you set in your build settings

[south sky]

Yo guys, the sprite of a character is moving in my game but I want the sprite of the character to flip when it moves in the other direction, how would I do this?

[hot palm]

Check it's velocity and flip the sprite renderer y

[open vine]

Is there an operator for if (x == a or b or c) then do this. Instead of having to write if (x == a || x == b || x == c)

[ripe shard]

Set the scale to a negative value

[south sky]

When what occurs?

[ripe shard]

A is B or C or D

[hot palm]

Bottom right you see the toggle for flip y, just access it through script

[south sky]

Cool thanks

[hot palm]

You can check in which direction it walks by looking at the x velocity (when you have an rb2D) or just have 2 variables get the last and the current position and check which one is smaller

[open vine]

what does the operator look like?

[south sky]

Can i also check if its vector is negative or positive?

[hot palm]

Well it's entirely up to you, depending on how you implemented moving

[ripe shard]

Literally that

[open vine]

LOL did not occur to me that "is" would be the actual one. Thanks!

[ripe shard]

if (a is 1 or 2 or 15) {}, more here https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/patterns

[hot palm]

fr

[south sky]

Cool

[south sky]

Wait tillydally the hit box wont flip if I flip the sprite

Any work aroud?

[hot palm]

Oh, then you have to make one parent game object for both and either set x scale to -x scale or rotate around the y axis by 180

Idk if this is code-based, but everytime I move my cursor in the editor, I get nullreferenceexceptions. Also this text blends in and out of existence, whenever I hover Debug Inspector?

[south sky]

Damn and i though your the one who knew everything lol

[hot palm]

Haha no no. I just learned by doing for 2 years. More complicated stuff will often exist

[teal viper]

What's in the callstack of the error?

[hot palm]

What do you mean? This are the errors

[teal viper]

Click the error and take a screenshot of it's details

[teal viper]

That's the callstack

[hot palm]

Okay

[south sky]

Why is unity screaming at me while throwing glass and food??

[hot palm]

Hover it

It should tell you

[teal viper]

Seems like a random unity ui bug related to the inspector. Does that happen if you disable debug inspector?

[hot palm]

I know it but try to figure it out yourself first

[hot palm]

No

[summer stump]

Can't set a component of a position like that

[hot palm]

But it's not workign as intended

[teal viper]

What's not working as intended?

[south sky]

Do you know any workaround?

[hot palm]

Does a canvas block raycasts?

[rich adder]

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

[summer stump]

Make a whole vector 3 and set position to it

[teal viper]

No. Raycasts are only blocked by colliders.

[hot palm]

It should display text now, which it doesn't (it sometimes does)

[summer stump]

Or multiply position by a vector with only x, times a float for the magnitude. Like Vector3.right

[rich adder]

well Physics ones 😅

there is Graphic raycaster which uses rect transforms or something

[teal viper]

How is that related to the error issue?

[south sky]

It may be a mimic careful

[hot palm]

I dp use a Physics.Raycast

[hot palm]

oh thx thx xD

[teal viper]

Yeah, but you can't cast ui raycasts afaik🤔

[polar acorn]

You cannot both get and set an individual component of a vector in the same line. You will need to either assign the entire position at once, or store the position a variable, modify it, then set it back

[hot palm]

When I tried troubleshooting that happened.

But dont need help for the X problem rn

[south sky]

Thank you man

[teal viper]

Ah, ok. Well, it's unrelated to the raycast. It's just something wrong with your inspector ui.

[south sky]

Ahh I see

[rich adder]

If you apply the Physics Raycaster it uses the Event System raycast to do IPointerHandler events on colliders

[teal viper]

Yes, but you can't cast them manually. I guess I assumed too much though. They could have been talking about the ui events.

[rich adder]

yea myb i just kinda butted in with no context lol

[hot palm]

Basically if UI in world space can interfere with collision and raycast

[rich adder]

it should not

[hot palm]

bcs I expierenced some weird UI behaviour regarding raycast before

Not in 3d tho

I think it was something like text making a slider area bigger or smth

[teal viper]

You can debug it really easy. Just print what your raycast hits

If it does hit the UI somehow, you will see it.

[hot palm]

true

[rich adder]

are you trying to hit a WorldSpace UI with FPS controller?

[hot palm]

No I want to evade that

[rich adder]

oh ok

you should be fine then

[hot palm]

I want to display world space UI when looking at a collider up to a max distance, but it jitters kinda

let me ask you more after troubleshooting this

[south sky]

People need to know about the Awake() method more its so good

Better than Start() imo

[hot palm]

Well it's important for static instances and referencing them in the start method

[rich adder]

they're very different methods

[teal viper]

Share a video of the issue

[summer stump]

Start just runs after awake. Generally you want to use them for different purposes. Neither is "better"

[rich adder]

its important for many reasons you would use a Constructor in a regular class

so like initializations

Start is better for Using the values from references like you said

also Start can be disabled via script checkbox, Awake cannot etc.
(Awake always runs on disabled scripts not disabled objects though)

[south sky]

wait it cant??

Damn

[rich adder]

nah unity runs awake when the instance is created

only game object starting disabled would prevent that

these methods * can be disabled from running ( i mean the checkmark in inspector myb)

[teal viper]

Actually, pretty sure awake is also affected by active/enabled state
https://docs.unity3d.com/ScriptReference/MonoBehaviour.Awake.html

[rich adder]

of the GameObject active state, not script .enabled

 private void Awake()
    {
        Debug.Log("Awake Ran");
    }
    void Start()
    {
        Debug.Log("Start Ran");
    }```

[teal viper]

Oh, I see.
The first paragraph in the docs was a bit confusing as it mentioned "enabled" components.

I guess it was me who had false memories after all.😅

Unity calls Awake when an enabled script instance is being loaded.

[rich adder]

ah yeah tha is confusing, I always assumed that to be like a traditional constructor

[toxic fossil]

I mean he proved his point with the gif

[rich adder]

when unity has a gameobject as active its running its own new()

which runs awake basically

[teal viper]

I see. That makes sense.

[timber tide]

and awake is basically useless for scriptable objects in the editor

q_q

[rich adder]

why's that?

[timber tide]

only called through a domain reload

[rich adder]

oh cause its like an Asset being created not a runtime thing

[timber tide]

yeah, it's silly

[rich adder]

I guess the whole AssetDatabase needs to update too

[timber tide]

So better off using OnValidate() or ISerialization interface, otherwise grab all scriptable objects and implement your own Awake

[rich adder]

no wondering i see OnValidate more often in SOs 😅

[south sky]

So uhhh any alternatives?

[teal viper]

You could use that to register an so with some static manager or something.

[teal viper]

distance.x = distance.x * -1

[timber tide]

right, usually the better idea. Also similar idea for plain c# objects

[carmine sierra]

quick question for documentation reasons, is there a point of oncollisionenter on a trigger collider

[teal viper]

What does the first error say if you hover over it?

[south sky]

There is no definition for scale and no extension called scale

[teal viper]

Because you might want to distinguish wether it is colliding with a collider or a trigger.

[carmine sierra]

okay thanks

[rich adder]

yes because there is no such property

[teal viper]

Ah, there's local scale only it seems.
https://docs.unity3d.com/ScriptReference/Transform-localScale.html
https://docs.unity3d.com/ScriptReference/Transform.html

[south sky]

So how can i "transform" the scale (get it)

[rich adder]

always check the docs/api when something doesn't quite line up

shouldn't your IDE have that in the suggestion box somewhere :p

[south sky]

Theres a problem bc I cant change the scale of the current gameobject the script is on

[summer stump]

Why not?

[south sky]

Yh it did but i was hoping you guys could explain it bc I didnt understant

Soz

[south sky]

Local scale is only for the parents right?

I may have read wrong

[rich adder]

🙂

[summer stump]

No

[south sky]

Ima try anyway

[teal viper]

It's what you see in the inspector, it's scale relative to the parent.

[rich adder]

local always means the child object and yeah like dlich said relative to parent

if the child has no parent, then local is just world

[south sky]

OOHHHH

[south sky]

Cool cool

Im learning

Thank you thank you

[hushed hinge]

I remember someone said with a video that I could also use a camera follow that doesn't just fully focused on the player like you can go to the egde a bit, but I don't remember where

[cosmic dagger]

cinemachine . . .

[hushed hinge]

which one? there's many

[rich adder]

https://docs.unity3d.com/Packages/com.unity.cinemachine@3.0/manual/CinemachineTargetGroup.html?q=target group
if you want both objects being kept in the frame

[cosmic dagger]

it's a package you import for the camera . . .

[hushed hinge]

I said "which one", because's there many different cinemachines

[rich adder]

in Package Manager there is only 1 Cinemachine package

[cosmic dagger]

huh? it's a single package . . .

[cosmic dagger]

@hushed hinge you can search or where the package manager is or how to import cinemachine. i'd look for a tutorial . . .

[rancid tinsel]

what can I use instead of a while loop here?

[cosmic dagger]

what are you trying to achieve?

[rancid tinsel]

text to appear and disappear every half a second, until the player has either ran out of time or the level has ended

but i havent implemented a level ending yet so just until they run out of time for nnow

[cosmic dagger]

what currently happens when you run the game?

[rancid tinsel]

it flashes but really glitchy

definitely nnot half a second

oh wait

i know what happened
