[rich adder]

ok you probably dont want those in the same statement tho. its not moving because the distance is never above 5

can you show me what kind of zoom you are doing with it, maybe there is a better way

[twin bolt]

I added a debug at where i increase the int, and it logs 5 times.

[oak cove]

"User
Error while saving prefab assets/VRTemplateassets/prefabs/setup/complete XR origin set up variant.prefab You are trying to save a prefab with a missing script this is not allowed"

Could someone assist me with this problem, I'm using the VR XR Template for Unity and this keeps popping up, I tried to delete it but thats not a good idea since it removes the entire VR camera, I haven't touched the variant and when I press save project the error pops up, I'm afraid that it will not save my entire project, is this the case or will it only not save that prefab?

[twin bolt]

While all of the texts are null

[slender nymph]

let me guess, you're just printing some arbitrary string instead of some actually useful info?

[slender nymph]

prove it

[twin bolt]

All of them look like this: https://i.imgur.com/FBmByk5.png

And yes i printed a string, when it increases it.

[slender nymph]

print some actually useful information

[twin bolt]

Like what?

[slender nymph]

like the string and its length?

[twin bolt]

it says that the length is 1, but it shows no text.

[slender nymph]

and you're not using IsNullOrWhitespace then

[twin bolt]

https://i.imgur.com/Pl28Jvy.png

[slender nymph]

well then whatever character is in there doesn't return true for char.IsWhiteSpace 🤷‍♂️

[crude prawn]

is this how you mean?

[slender nymph]

sure

[polar acorn]

Try this log, I have a hunch:

if (e.Length > 0){
  Debug.Log((int)e[0]);
}

[slender nymph]

was your whitespace character issue caused by a character added by a tmp input field?

[polar acorn]

Sorry, java brain, you can just list index to get a char from a string

[crude prawn]

instead of this how should i subscribe to the event?

[polar acorn]

yes

it was exactly that

Char 8203

U+200B

[slender nymph]

damn tmp adding non-standard whitespace characters

[slender nymph]

like that but with both started and canceled

[twin bolt]

That outputs 8203

[polar acorn]

Yep that fucker again

It's a non-zero, non-whitespace, non-control invisible character a.k.a. an absolute bastard to find

[slender nymph]

honestly this should be reported as a bug. they shouldn't be using a whitespace character that isn't actually considered whitespace as a placeholder

[crude prawn]

u should report this to unity staff

[polar acorn]

But thankfully very easy to remove, let me go find my solution from the other day

[twin bolt]

So should i just check to see if texts length is higher than 1?

[slender nymph]

no, trim that character out of it

[polar acorn]

I'm opening up my project to find the right way to replace it out, hang on

[slender nymph]

should just be Trim('\u8203') right?

[polar acorn]

.Replace("\u200B", "")

[slender nymph]

ah right, 200B is the unicode for it. 8203 is the actual char value

[polar acorn]

Call that on your string that you get from the input and that'll replace that character with nothing. Then you can IsNullOrWhitespace it

[summer stump]

Is this what that duplicate (but not recognized as equal) path issue ended up being?

[twin bolt]

https://i.imgur.com/Xi3jxVt.png

like this?

[polar acorn]

Yes

[summer stump]

Crazy, I'm glad I saw this conversation!

[polar acorn]

You'll need to do it where you're reading it from. Any time that input field changes it'll put the character back

[twin bolt]

Okay

[slender nymph]

replace returns the new string. so you need to store the result in a local variable and use that for your checks within your other loop

strings are immutable so they cannot be altered in place

[twin bolt]

Thank you that worked

[slender nymph]

interestingly this doesn't appear to happen when referring to the TMP_InputField directly. only when referring to the child Text object (at least in 2023.1.19 which i tested in)

[rich adder]

thats kinda wild..

[slender nymph]

i didn't find anything in the issue tracker about this, so i submitted a bug report. hopefully they'll use a different whitespace character that actually does return true when checking for whitespace

[chilly estuary]

i'm back with the code guys

the rotation point is veeeery buggy

[rich adder]

jesus that GPT code..

and its wrong

ofc

targetPos should be distance from cam

[chilly estuary]

yeah lol

[rich adder]

Input mouseposition is a vector2

well technicaly v3 but its pixel coords

Vector3 for "compatibility"

[chilly estuary]

so what should i do

[rich adder]

Vector3 mouseWorldPos = Camera.main.WorldToScreenPoint(Input.mousePosition);
        mouseWorldPos.z = distanceFromCam;```

direction prob needs .normalized too

[chilly estuary]

where do i put it

[rich adder]

this is why you should not use AI to write code for you

You're not familiar with your own code, and you won't know what to do with it when it breaks

[chilly estuary]

i normally dont use it, but i have no idea on how i can make it work

[rich adder]

are you working in 2D?

[chilly estuary]

yeah

[rich adder]

so why don't you look at old forums of unity that has been asked how to do this a billion times

read what actual people are saying

[rich adder]

which way is your sprite pointing, right or up

[viral hemlock]

quick question what is the difference between LoadScene and LoadSceneAsync

[rich adder]

one is async and one is not

[viral hemlock]

what does async change

[rich adder]

it runs async, parallel

in the background

[viral hemlock]

oh ok

[rich adder]

so you can implement loading screens or something because you have "progress" till its done doing task

some stuff that takes time is better to use async

like doing large operations that can hang UI

[pliant oyster]

How do I switch my entire game to Mono audio via code?

[rich adder]

cant u just set the spatial blend from 3d to 2D ?

[pliant oyster]

I don't know what that means. I want the user to be able to press a button and have the audio switch to mono, and they can press the button again to put it back to stereo

[rich adder]

I don't think you can natively change stereo to mono in unity without Fmod

[pliant oyster]

Okay, I'll try

[raw hamlet]

How do I reference a prefab with a gameobject?

[summer stump]

public GameObject myPrefab;

[raw hamlet]

I keep getting this error

[summer stump]

Or better yet, use the thing you want to reference

[raw hamlet]

in the inspector

[summer stump]

Well what type is ObstacleSpawner?

And what are you trying to drag in?

Hopefully not a scene object into a prefab

[raw hamlet]

it is

[rich adder]

that wont work

[raw hamlet]

I know you can't do it but what is the workaround it?

[summer stump]

Can't do that

[summer stump]

What is the goal?

[rich adder]

pass it from something that spawns it already in the scene

[raw hamlet]

wdym

[rich adder]

https://unity.huh.how/programming/references/prefabs-referencing-components

see example ^

[raw hamlet]

I already read the link but i didn't understand it

that is why i came here

[rich adder]

which part you not understand?

[summer stump]

#💻┃code-beginner message

We need more info before we can give the best help
Show the prefab and the scene object

[rich adder]

true, provide context to what your code does/needs to do

[raw hamlet]

Im trying to get a variable from the obstaclespawner script

this is the scene object

this is the prefab

[summer stump]

Is the prefab spawned by the obstacle spawner?

[raw hamlet]

yes

[rich adder]

Obstacle spawner can pass itself to the prefab

[summer stump]

Then give the variable when you spawn it

[raw hamlet]

how do i do that?

Instantiate(obstacle, new Vector3(9, pos * 4.5f, -1), Quaternion.identity);

this is how i spawned it

[rich adder]

using the keyword this

[summer stump]

ScriptIWant newThing = Instantiate(thing);
newThing.variableICareAbout = value;

[slender nymph]

if only someone gave you a link that tells you how to reference other objects and pass references to objects 😉

[raw hamlet]

ik

but as i said i didn't understand it

[rich adder]

yeah think they're confused by Transform, you can also pass other types like a script

[raw hamlet]

thank you for your help tho

[raw hamlet]

ScriptI want is the prefab right?

[summer stump]

Yes. Just make the prefab type the actual script, not GameObject

You can drag in a prefab with that script, instantiate it, and it'll copy everything on the attached gameobject

[raw hamlet]

DestroyOutOfBounds destroyOutOfBounds = Instantiate(obstacle, new Vector3(9, pos * 4.5f, -1), Quaternion.identity);
``` like this?

[summer stump]

Sure, if obstacle is of the type DestroyOutOfBounds

[rich adder]

 public class ObjSpawner :MonoBehaviour
    {
        public void Spawn()
        {
            var myObj = Instantiate(etc.)
                myObj.Init(this);
        }
    }
    public class DestroyOutOfBounds : MonoBehaviour
    {
        ObjSpawner _objSpawner;
        public void Init(ObjSpawner spawner)
        {
            _objSpawner = spawned;
        }
    }```
another example

[raw hamlet]

why the _ before variables?

[summer stump]

Then no, change it from GameObject to DestroyOutOfBounds like I said

[summer stump]

Just a style

[rich adder]

dont worry about this, just means it private variable (just a label)

[summer stump]

public DestroyOutOfBounds prefab;

void SpawnMethod()
{
DestroyOutOfBounds newThing = Instantiate(prefab);
newThing.variableICareAbout = value;
}

Maybe that's clearer?

[raw hamlet]

I tried doing this but I am assigning an object to a script

so it is giving me an error

[summer stump]

Show the code

[raw hamlet]

I don't know how to make it the same like you said

[rich adder]

you change the original declared type

[raw hamlet]

public class ObstacleSpawner : MonoBehaviour
{
    // Start is called before the first frame update
    public float spawnInterval = 2;
    public float timeSinceSpawned = 0;
    public GameObject obstacle;
    public int counter = 0;
    int pos;
    public int scoreCounter = 0;
    public DestroyOutOfBounds prefab;
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        timeSinceSpawned -= Time.deltaTime;
        if (timeSinceSpawned < 0)
        {
            if (counter == 10)
            {
                counter = 0;
                spawnInterval -= 0.1f;
            }
            timeSinceSpawned = spawnInterval;
            int choice = Random.Range(1, 3);
            if (choice == 1)
            {
                pos = 1;
            }
            else if (choice == 2)
            {
                pos = -1;
            }
            DestroyOutOfBounds prefab = Instantiate(obstacle, new Vector3(9, pos * 4.5f, -1), Quaternion.identity);
            counter += 1;
        }

    }
}

[rich adder]

u switched them

[summer stump]

Change obstacle to DestroyOutOfBounds

You can drag a gameObject into that as long as it has that script

[rich adder]

I think obstacle and prefab might be diff things

[summer stump]

public class ObstacleSpawner : MonoBehaviour
{
    // Start is called before the first frame update
    public float spawnInterval = 2;
    public float timeSinceSpawned = 0;
    public DestroyOutOfBounds obstacle;
    public int counter = 0;
    int pos;
    public int scoreCounter = 0;
    public DestroyOutOfBounds prefab;
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        timeSinceSpawned -= Time.deltaTime;
        if (timeSinceSpawned < 0)
        {
            if (counter == 10)
            {
                counter = 0;
                spawnInterval -= 0.1f;
            }
            timeSinceSpawned = spawnInterval;
            int choice = Random.Range(1, 3);
            if (choice == 1)
            {
                pos = 1;
            }
            else if (choice == 2)
            {
                pos = -1;
            }
            DestroyOutOfBounds prefab = Instantiate(obstacle, new Vector3(9, pos * 4.5f, -1), Quaternion.identity);
            counter += 1;
        }

    }
}

[rich adder]

prefab needs to be named something like currentObject or instance

w/e

[summer stump]

Prefab is the refernce to the new object

[summer stump]

Yeah. Should be

[rich adder]

DestroyOutOfBounds destroyOutOfBoundsInstance = Instantiate(prefab, new Vector3(9, pos * 4.5f, -1), Quaternion.identity);

[summer stump]

Makes waaay more sense 👆

[raw hamlet]

how do I pass the variable scoreCounter into the DestroyOutOfBoundsInstance?

[summer stump]

Wait, doesn't that script have the variable?

If not then why use that as the type?

[rich adder]

why does destroyOutOfBoundsInstance care about scoreCounter anyway ?

[raw hamlet]

Original goal: From the DestroyOutOfBounds script, I am accessing the scoreCounter variable from the ObstacleSpawner script. Then I update the variable to whatever score I want

[raw hamlet]

it adds a score of 1 whenver an object is destroyed

[summer stump]

Sounds like you want an event

[rich adder]

gotcha. so just make a method to call

[summer stump]

And subscribe to it when you instantiate the obstacle

[rich adder]

this^ although events for them rn might be 🤯

[summer stump]

Or that
#💻┃code-beginner message
And just have the reference to the script and call it later

[rich adder]

please dont keep score in ObstacleSpawner next time

just made everything so much more confusing

[raw hamlet]

Ok sorry

[rich adder]

its ok. just remember every script should serve one purpose (for the most part when possible)

ObstacleSpawner spawns obs, it should not care abbout score , thats for ScoreManager

which could be in this case even a singleton

otherwise atm you pass ObstacleSpawner reference on spawn and call method or just do obstacleSpawner.score++
Shown here
#💻┃code-beginner message

[raw hamlet]

That is a good idea. I have a bad habit of just one giant chunk of code

ok

[rich adder]

yup its easy in the beginning in one file /script , but once you start adding more and more functionality it gets over-convoluted spaghetti

[static cedar]

Something Microsoft recommends for private variables in classes but i personally couldn't care less.

[rich adder]

eh sometimes , I do it some times I don't. its no big deal.
Makes finding a variable in IDE that much faster

[static cedar]

Personally, if i want to find smth, i usually just hover over a variable.

[rich adder]

no I mean as you're typing

sometimes intellicode suggests a class or something unrelated as you type a variable name

as soon as you do _

intellisense brings up all your private vars

[raw hamlet]

another newbie question

I have a text for gameover

I want to hide it at the start but not disable it

I already tried setactive but it disables the whole thing

[static cedar]

I think it would be smarter than that tbh.
But i'm guessing you do this to navitate by using arrow and tab keys from available selection?

[raw hamlet]

how do i make it so only the Text part is disabled?

[static cedar]

In script?

[teal viper]

Disable the text component.

[slender nymph]

1. don't use legacy text, use TextMeshPro
2. just disable the component. but also why not disable the entire gameobject?

[raw hamlet]

why is legacy text bad?

[teal viper]

But also, if you have other stuff on it(like an image), better split it into several objects

[slender nymph]

because it is worse in nearly every way compared to TMP. but if you want blurry text then feel free to keep using it 🤷‍♂️

[rich adder]

If you type a looking for awesome variable , VS brings up unrelated suggestion like async keyword..
having _ it immediately brings up all my private vars

[raw hamlet]

i guess it is blurry

[rich adder]

even if I named it awesome

without _

it still brings async as keyword

too slow

[static cedar]

Huh, i thought the suggestions would be smarter than that. 🤷‍♂️
I just know what var names to type so i never have a personal issue with this stuff.

[rich adder]

we each have our preferences and workflows 🙂
i just found it personally speed up mine

I've seen it a thousand times.

[rich adder]

idk I never used debugger on VSCode so I couldn't tell ya

VS is plug n go

[rich adder]

did you do the original configuration first ? like setup external tools and update PM VS package ?

[amber dome]

any possible alternative to External IDES, or not using debugger?

[lucid jetty]

share code

[rich adder]

yes Visual Studio

[amber dome]

ohhhhh, right

I've tried using that one too, but it still has the same error.

Is the latest version of dotnet not supported by Unity?

https://gyazo.com/2f1fdd1f3eecfbfc4548a1295e78bf36

like this?

[summer stump]

It is not

[amber dome]

I downloaded version 7.0

[summer stump]

You don't need gyazo, just drag the image directly into discord

[amber dome]

Are errors linked to this?

[rich adder]

yes it looks fine here

[summer stump]

You need standard 2.1 or framework 4.8
Or both?

[lucid jetty]

gyazo is easier to make screenshots and i dont need to remove the screenshots afterwards 😉

[rich adder]

doesnt the sdk include all of them

include past ones

[amber dome]

4.8

[summer stump]

I am not sure honestly, that's just what the api compatibility page lists haha

[rich adder]

oh ok lol
someone said they installed the SDK from site and then it started working

[amber dome]

I don't understand why this happened suddenly.

For now, I'm going to give up.

Thank you all for your support!

[lucid jetty]

do you know the problem maby?

[rich adder]

because they've been updating it and breaks stuff

[amber dome]

To use Unity, do I have to define a version that is supported?

On Godot, the same error is also occurring, so initially I thought it was on dotnet itself.

[rich adder]

this has nothing to do with unity itself

its the extensions in VSCode that are shite

they haven't reached 1.0v afaik

and will be buggy for a long time

Visual Studio is better because its a mature code editor

[amber dome]

No way to code within Unity? no support from External IDES.

"Assembly-CSharp (Incompatible)"

what?

[rich adder]

right click on it and do Rebuild

[slender nymph]

Reload With Dependencies

[amber dome]

what?

i'm noob.

[slender nymph]

right click it and select Reload With Dependencies

this is assuming you've actually done the rest of the configuration steps, of course

[amber dome]

Where is that option?

[slender nymph]

you see the option when you right click an unloaded assembly

[amber dome]

And how do I find this unloaded assembly?

[slender nymph]

it's this

you do have eyes, right?

[static cedar]

I think it's more that he doesn't really know what the assembly is.

[amber dome]

I did here already, has an option to download

[slender nymph]

the option, when viewed in English is Reload With Dependencies. i do not read the language your IDE is currently set to so i cannot provide more information beyond that

[amber dome]

I've already managed to reload the dependencies

What should I do now?

[slender nymph]

does it work?

[amber dome]

it runs, normally (according to the IDE) but in unity, I don't get any results in the console.

[slender nymph]

what are you referring to?

[rich adder]

do you see your scripts / folders in Solution Explorer?

[amber dome]

I only see the Assets folder and the script.

[rich adder]

is it still saying Incompatible ?

[amber dome]

no

After I reloaded it disappeared.

[slender nymph]

then congrats, it works

[rich adder]

ok so now it says ?

good

[rich adder]

now you have a real code editor

[amber dome]

Now to run the written code, I have to click attach to Unity, right?

[slender nymph]

that's just to use the debugger

you enter play mode from within unity

and to see your log you need to actually have your component attached to an active object in your scene

[rich adder]

lol have you been trying to run playmode from editor this whole time ?

[amber dome]

yes

I'm a beginner

[rich adder]

oh well something positive you got a working IDE now

future headaches avoided

[amber dome]

yes, now I've got it.

I never use VSCode again. 😦

[slender nymph]

now you should start with some beginner unity courses like the pathways on the unity !learn site to learn how to correctly use the editor 😉

how do i disable a collider on an object in code?

[ivory bobcat]

https://docs.unity3d.com/ScriptReference/Behaviour-enabled.html

[silver dock]

how do i add visual tap/click feedbacks? there is like no video for it on youtube at all

[rich adder]

just put a certain texture/sprite at the touched positions

[silver dock]

i tried that, its not visible for some reason

is it cause the whole game is played on UI canvas?

[rich adder]

then you probably spawning the wrong positions

UI canvas positions are diff than world pos

[silver dock]

Yeah, whats the line of code for referencing where u touch on the ui?

[rich adder]

it should still work tho

[rich adder]

how are you grabbing touch pos

[silver dock]

if (Input.GetTouch(0).position)

[rich adder]

show full script

[frozen dagger]

how to set rotation?

[rich adder]

Euler angles

[frozen dagger]

what?

[rich adder]

transform.Rotate

[frozen dagger]

ok ill try

bruh, i wanted to set value, not add it every time

[rich adder]

transform.localEulerAngles

[ivory bobcat]

i'm still stuck on this player movement for 2d, here is the script https://paste.ofcode.org/Qx4CWBArLabBzp7mbhwGCM

and here are the errors

basically im trying to create a script with some custom sprites

[ivory bobcat]

Duplicate script or rename bug

[reef patio]

what?

[polar acorn]

Do you have these errors in unity or just the ide

[reef patio]

in the IDE

ill check Unity

ok fixed

I understand now Dalphat

[ruby gull]

I am watching a youtube tutorial and this is how the tutorial makes sure the player moves with the moving platform. But something smells here, setting the platform to be the parent of the player feels like a really bad practice. Is my hunch right?

[reef patio]

does anyone have a link for a 2d movement lesson?

the script I shown was some dud

[summer stump]

Honestly, that doesn't look too bad. I like that you tried those variants of movement. One thing with the velocity (variant 2) is that you may want to have the y velocity be set to its own y velocity or a negative number to avoid floating in the air.

When you use Get for the input and use that directly, it will be setting your y velocity to 0 every frame. 0 velocity meaning trying to not move up or down.

Now, some 2d is just walking on the ground all over (like pokemon style maps/movement), but a platformer would have obvious issues with that

[reef patio]

The whole plot of script lead to a 2d sprite moving on its own.

[summer stump]

Hmmm... i am not quite sure what that means..

[reef patio]

The character I set does not connect right to the player animations, he just moves on its own without me typing a key.

I can show a video.

[summer stump]

Ah, you should have the SetFloat methods outside the if check

You only set the float when it is NOT 0
But you want it to STOP sometimes, so you need it to be set when it IS 0 too

Something like this (untested, and doesn't address the issue with Y velocity I mentioned above):
https://paste.ofcode.org/ts3KyPKq8XaWWh5TLJAs3U

[eternal needle]

its something that works purely for the purpose of the tutorial, which is what most tutorials are for. This would also break rigidbody movement (since directly updating transform does not respect physics).
The whole collision.gameObject.name part is pretty bad too, you dont want to rely on the name of the object. You could do layer based stuff, or whatever else to extend this to work on other objects as well.
Parenting an object will also affect rotation and scale so thats also a negative

[ruby gull]

yeah felt like this was the case, what would the idiomatic way be to achieve this?

[silver dock]

Can someone tell me why is HideFeeback() being called even without releasing the mouse button

https://hatebin.com/drmnwfqwfe

[charred spoke]

Moving the player with a platform? On collision get a ref to the platform, add it’s velocity to the char controller velocity.

[reef patio]

he is moving without key pressing

[eternal needle]

I think a slightly better way would be applying a move (respective to how your player moves whether rigidbody or adjusting position) to objects on the platform instead of parenting it. This would still allow you to make sure its not teleporting the player into walls when the platform goes under one for example

[ruby gull]

alright thanks for the help, guess I'll also need to change how the moving platforms work, cause right now I am updating their positions directly in the script, instead of using physics

[charred spoke]

You can just calculate a velocity from that and pass it to the player

You dont need a rb per platform doing unnecessary calculations

[ruby gull]

oh yeah, true, I can use the move speed value from the platform script to calculate the velocity

thx

[eternal needle]

you dont have to use physics, but just some movement that respects collisions in your world. Like casting along an area to see if you can move there is valid

[summer stump]

Looks like you don't want gravity there. Not 100% used to 2d (usually do 3d) but I think you can just set gravity scale to 0.

[summer stump]

Also see this for a separate issue I noticed
#💻┃code-beginner message

[silver dock]

anyone?

[reef patio]

Ok he stopped.

But he is not able to move.

[summer stump]

Show the PlayerInput component

[summer stump]

You have no Input Action Asset, and thus no OnMovement message is being sent

Do you have an Input action asset created? You just have to drag it into that top box

[reef patio]

No.

[reef patio]

I have that.

[summer stump]

What they had already wouldn't show without that, just fyi

[rich adder]

click Create Actions

its better

it makes default wasd

[reef patio]

Ok I created one.

no one is really helping him so i stepped in

Its only when the wrong stuff is given people speak up lmao

I should do it more often

[rich adder]

you realize people are doing other stuff too

[tepid cobalt]

triggered lmao

[summer stump]

Stop or leave.

[summer stump]

Ok, you need an action called Movement (exactly that). Then the message will be sent to OnMovement

[reef patio]

Ok.

Action Maps _ Movement > "New action" +

[summer stump]

Did you do it the way Navarone said? Click Create Actions on the Player Movement component?

[reef patio]

I can't find that.

[reef patio]

Oh that one.

Ok, done.

[rich adder]

looks like you already created on before clicking it?

[reef patio]

is that ready?

[summer stump]

Yeah, change your code to say "OnMove" though

Instead of OnMovement

The default action is called Move I guess, thus the need for the change

[reef patio]

Which code?

[summer stump]

Your movement code

This
#💻┃code-beginner message

[reef patio]

Oh, the script?

Ok, done.

[summer stump]

Give it a try. Can you move?

[reef patio]

Nope.

I may have lost my animator scripts.

Theirs a console problem.

[silver dock]

please anyone 😭

[summer stump]

Is there an Animator on the player?

[reef patio]

Ok, found it.

I was able to change the direction.

Then a error appeared.

I deleted "IsWalking".

[summer stump]

Looks like the animator is just not set up. You have an event with no listener

And I guess that would explain the warning haha

[reef patio]

That's the animator.

It should have some done for directional looking.

The 4 directions.

[pine bay]

Hey, I want ask. So i have an inventory system in my game. At first I have two object that can pickup to my inventory. a cutter and a soda can. I pick the two object to my inventory, as you can see in the image. Then, when i exit the game and play it again. All my item change into soda can.

here is my code

[summer stump]

You call FindItemOfType<Pickup> and instantiate that for every filled slot in the LoadInventory method

Seems like that may be an issue.

Is the SodaCan of type pickup?

[pine bay]

yes the sodaCan type pickUp

[summer stump]

It's complaining about an AnimationEvent.
Might wanna take this to the #🏃┃animation channel. I'm not great with animations

[summer stump]

So then I'm not sure what is expected in the LoadInventory method.
It finds a single random PickupInstance (a sodacan in this case) and loads that into every slot

[pine bay]

what i must do sir, deleting the pickupinstance line of code?

[summer stump]

Well you probably want to SAVE what was in the slot, right?
As of now, you only save if it is filled or not

And yeah, calling Find to get a random instance is not a good way to go about this

You could save a string, or an enum, or even an int. Just something to represent what was in the slot

Then you load that value and populate it properly

[pine bay]

thanks for the answer sir, i'm still figuring out

[summer stump]

No problem! I'm off to bed but if you still need help when I see it tomorrow, I'll try to help. Good luck!

        }
    }

this script some how does not work though can anyone help

[gaunt ice]

the sword can only facing one direction, so you should reset all the directions no just the opposite direction
consider translation from left to up, you set down=false but not left

btw you can use a enum not four bools

[stoic lichen]

Hey guys!
I am working on an AR app for Google Play store and Apple app store and it is huge as it includes a lot of 3d models and meshes.

I tried using the Play Asset Delivery Package to create my App Bundle but the Upfront Asset Pack created is larger than 1GB which is the limit.

Can someone help me with this? I have already completed development and just need to publish now.

[weak talon]

i know why it isnt working
the sword is set to inactive
if i press mouse button 0 it sets active
do you know how i can change rotation of the sword even when it is inactive

[gaunt ice]

you can still change transform or other components of inactive gameobject from other scripts
but the update on inactive gameobject will not be called

[weak talon]

ok thank you

[compact ibex]

Hi, i would like to extract the coordinates of a vector from another one in an efficient way, for example if the player transform.forward = (1,0.5,1) and the transform.up = (0,1,0) then by extracting the up from the forward, we would have something like extractedDirection = (1,0,1) - so basically setting 1 coordinate to 0 depending on the up vector.

[gaunt ice]

it seems that you set the only one component to be 0 based on the non zero component of up vector
how about if you have a up vector eg (0.316, 0, 0.948), so which component of (1,0.5,1) will you set to 0?

are you trying to project a vector to a plane formed by transform.up? i dont understand what you mean actually

[compact ibex]

problem with this is i can only have the up vector facing in cardinal directions, it won't work if the transform.up is (0.6,0.5,0.88) for example, but that's kind of the spirit yes

[compact ibex]

Also yes, you can imagine this like i would try to project the red cubes position onto the greens plane formed by its up vector (this plane is represented with a blue arrow because then i get the direction from the green cube towards the red dot which is the projection)

but you can also think about it like trying to point a vector towards the red cube and then negating the up component

which ever of these to is more efficient and easier to do

[gaunt ice]

just A-B and set y=0 if the transform.up always (0,1,0)
a faster way is to calculate x and z components only

[compact ibex]

it's not always (0,1,0) haha that's why i'm trying to do all this

[gaunt ice]

so only one component will be 1 if my understanding is correct?
check which component is non-zero and calculate the remaining two components

[compact ibex]

well for now i only need cardinals yes but this might bite back later if i need all directions, i'm just gonna try like this for now

actually i found a good way to do it :
Vector3 directionVect = (targetPoint - transform.position);
Vector3 factor = Vector3.one - transform.up;
direction = Vector3.Scale(directionVect, factor);

[solar heron]

can anyone help me? im trying to make a Tower Defence game on 2D and is trying to make a remove tool and for some reason it not colliding? I am very confused, the part has a collider and everything here has a collider. I can send you the code here:

using JetBrains.Annotations;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Remove : MonoBehaviour
{
    [SerializeField] bool isTouching = false; 
    // this is just a test to see if collisions work
    public void OnTriggerEnter2D(Collider2D obj)
    {
        if (obj.gameObject.CompareTag("RemoveTool"))
        {
            isTouching = true;
        }
        

    }
    public void OnTriggerExit2D(Collider2D collision)
    {
        if (collision.gameObject.CompareTag("RemoveTool"))
        {
            isTouching = false;
        }
    }
}

Anyone who can help me..? 😭 About Coroutine Error...

https://pastebin.com/WkEtt0L8

Another error was Coroutine couldn't be started because the the game object is inactive!...

but not now. I don't know why

[short hazel]

The error you screenshot is internal to Unity, it does not come from your own code, you can ignore it

And the error about the coroutine is pretty self-explanatory, you cannot start a coroutine on an object that's inactive

[vital sail]

Coroutine Script was applied to monsters(prefab) placed on the screen. If I have to activate it separately, how can I activate it?.... I can't understand it even if I look it up...

[timber tide]

You only need one object with a rb, and you can set it to kinematic, otherwise you could just use overlapcircle to grab collider info through update

[solar heron]

Also how do I make 2 hitboxes, one for placing, one for removing

[short hazel]

And the code that stores the coroutine is also incorrect. It should be something like ThinkEn = StartCoroutine(Think());. Currently you're starting two coroutines, you have another Think() above or below.

The error you're getting can happen if one script on an object tries to start a coroutine on another script in another object

[timber tide]

Well, depends how you want to do it, but since you're using 2D you can target indepedent objects, or a point on a plane

[solar heron]

I want a smaller hitbox for removing and a bigger hitbox for placing so the circles dont collide

[timber tide]

Overlap circle may be ideal then and you can cast it at your pointer with different radius

[solar heron]

Please explain this to me like i know nothing because i have no idea what you just said lol

[timber tide]

Have you used any sort of raycasting before?

[solar heron]

Nope, only in roblox studio (my former game engine)

[timber tide]

Right, so overlapcircle basically just detects all colliders at a given point in a specific radius

[solar heron]

wdym like a trigger?

[timber tide]

https://docs.unity3d.com/ScriptReference/Physics2D.OverlapCircle.html

You give it a point in world space, and the radius of the circle. When it detects colliders you'll get an array of gameobjects that were within the radius. In this case you can check if there's currently objects occupying a space.

[solar heron]

i am gonna save this for later thank you, ill try to fix this and if it doesnt work ill use this

[timber tide]

Probably look around for better examples since the documentation stinks ;)

https://medium.com/geekculture/how-to-detect-colliders-surrounding-the-player-ebdcadf3ba61
Good snippets of code there

[solar heron]

I dont want an aoe thing, i wanna delete an object 1 by 1 but thanks for the info

[timber tide]

If you're trying to detect an area to put a unit down you'll need a way to check it first and this is what you'd probably want to use.

[vital sail]

Thank you! I'll try it!

Happy Saturday all, I'm having a little trouble figuring out where to disable an object in my scene, would someone mind taking a look and pointing me in the right direction please? 🙂

RaycastHit weaponHit;
                if (Physics.Raycast(firingPoint.transform.position, firingPoint.transform.TransformDirection(Vector3.forward), out weaponHit, weaponRange, weaponImpactMask))
                {
                    Debug.Log("Hit - " + weaponHit.transform.gameObject.name);
                    Vector3 hitPoint = weaponHit.point;

                    if (weaponHit.transform.gameObject.CompareTag("EnemyCollider"))
                    {

                        MimicSpace.Mimic currentMimic = weaponHit.transform.parent.GetComponent<MimicSpace.Mimic>();
                        GameObject healthBar = currentMimic.transform.FindChild("MimicHealth").gameObject;
                        healthBar.SetActive(true);
                        if (currentMimic != null)
                        {
                            currentMimic.TakeDamage(damageDealt);
                        }
                    }
                    AdjustWaterStreamLength();
                }
                else
                {
                    AdjustWaterStreamLength();
                }

Basically I need the health bar to disappear when the ray is no longer hitting it.

[timber tide]

Why not just deactive it in the else statement there?

[ruby python]

It doesn't exist in the else.

[keen dew]

Make healthBar a field instead of a local variable, then it does

[timber tide]

You could poll each enemy independently to just set their hp bar off too, but this requires some ordering on the execution of the updates to work.

[ruby python]

Hmmm, I guess it would probably be easier to put the enable/disable code on the enemy itself, maybe compare currentHealth to previousHealth? Unless there's a way that I can have the enemy detect when it's hit by the raycast?

[timber tide]

Some ideas I'm thinking too is that you could create a buffer such that it stores the most current enemy you've have highlighted, and when you target a new enemy then you'd set the previous enemy healthbar to off and enable the new enemy's bar.

Would eliminate any polling

Well, I guess you'd have to check if you're currently highlighting anything.

[ruby python]

Hmm.....okay, this is what I'm trying on my enemy script. It enables fine but doesn't disable, so I'm not sure on the logic....

public void TakeDamage(float damageAmount)
        {
            float previousHealth = health;
            health -= damageAmount;

            if (previousHealth > health)
            {
                mimicHealthDisplay.SetActive(true);
            }

            if (previousHealth == health)
            {
                mimicHealthDisplay.SetActive(false);
            }

            mimicHealthBar.rectTransform.localScale = new Vector3(health / 100, 1, 1);

            if (health <= 0f)
            {
                DestroyMimic("Shot");
            }
        }

[gaunt ice]

previous health never == health unless damage is 0

[ruby python]

Yeah I realised the 'SetActive(false)' will never be called in this method. lol. I hate game logic sometimes.

[timber tide]

Mimic currentTarget;

private void RaycastMethod()
{
  ...
  
    if (weaponHit.transform.gameObject.CompareTag("EnemyCollider"))
    {

        MimicSpace.Mimic currentMimic = weaponHit.transform.parent.GetComponent<MimicSpace.Mimic>();
          
        if (currentMimic != null)
        {
          ChangeTargetHealthbar(currentMimic);
          currentMimic.TakeDamage(damageDealt);
        }
    }
}

private void ChangeTargetHealthbar(Mimic newTarget)
{
    currentTarget.healthbar.gameobject.SetActive(false);
    currentTarget = newTarget;
    currentTarget.healthbar.gameobject.SetActive(true);
}```

If you can target multiple mimics at once and you want to see all their healthbars my other idea is to do a coroutine instead and make their health appear for a set amount of time as you damage them, refreshing the coroutine on each hit.

[ruby python]

It's just one at a time (essentially point and click/hold)

gimme a couple of minutes.

Okay, well it appears OBS or streamable blew out the colouring seriously badly, but should give you an idea of what I'm doing 🙂

Is there a way to only make the wall move forwards on the X axis? It is moving on the Y axis now and it looks weird.

I know the script is handling stuff it shouldn't, but this is a testing script. Everything else will be subsumed into the Scene Change Event System later

[thorn holly]

It’s because the player’s position is lower than the wall’s.

So it moves down towards it

[silent idol]

I see, is there a way to lock movement on the Y axis?

[hexed terrace]

just don't change the value of Y

[thorn holly]

Maybe, but what you could do instead is say transform.position = new Vector2(Vector2.MoveTowards(this.transform.position, player.transform.position, monsterSpeed * Time.deltaTime).X, transform.position.y);

[silent idol]

So the transform position of y is stable?

[thorn holly]

Yes, that will basically set the x to your old code and lock the y to whatever is was at the moment

[hexed terrace]

a more readable way

var newPosition = new Vector2(player.transform.position.x, transform.position.y);
transform.position = new Vector2(Vector2.MoveTowards(this.transform.position, newPosition, monsterSpeed * Time.deltaTime);```

[thorn holly]

Yeah ^

[silent idol]

[cinder plover]

Why does the mesh not go invisible?

Why would it? You never call the method.

I do here, and the debug log is in the command prompt

like i get the message it activated

Then add Debug.Log("Activated", gameObject); then you can click the log and see what gameobjects renderer get enabled and disabled.

Strange that it prints twice, but you can click it and see what object got disabled.

[cinder plover]

Nah i just didnt remove the first log

it activated once

and when i click on it nothing happens

nvm

but how does this help me

[fossil drum]

Yeah, that one should get disabled then.

[cinder plover]

well its still visible

[fossil drum]

Did the components get disabled?

[cinder plover]

i dont think so

should this uncheck?

[ivory bobcat]

Well that's the point. Verify it.

[cinder plover]

cuz it doesnt

[ivory bobcat]

That's not the component, that's the object.

[fossil drum]

These are components you want to disable.

[cinder plover]

yeah it doesnt disable

[ivory bobcat]

You wouldn't disable an object. You'd deactivate an object.

The components should have been disabled.

[cinder plover]

what do i do if they werent disabled

[ivory bobcat]

Figure out why. The code says they were during runtime/execution

[fossil drum]

Make sure you don't call it twice for one. That way you would get back were you started.

[cinder plover]

i only call it once

[ivory bobcat]

Log something more relevant

The state of the components

[fossil drum]

What my guess is, is that SkinnedMeshRenderer derives from Renderer, and you get the same component, and disable and enable that one.
But you could check that with the logs.

[fast oracle]

For some reason this code is making my gameobject move directly up even when I rotate it

[fossil drum]

Yeah, you simply add more y to your localPosition. So always up.

[ivory bobcat]

You're only moving directly up locally

[gaunt ice]

you should use transform.up

[cinder plover]

Ty you so much, this wasnt exactly it, but i fixed it, this was the problem:

Im dumb af

[ivory bobcat]

Thought that was intentional

[cinder plover]

Lmao i just missed one number

[thorny garnet]

i am a noob and i have a couple questions [:

[gaunt ice]

just ask

[fast oracle]

do I keep the vector3 the same?

[thorny garnet]

the event functions of Update and FixedUpdate confuse me, i know that framerate can vary wildly on machines so why would anyone use Update instead of FixedUpdate

[dry smelt]

About to get a laptop with rtx 4050, is this good enough for Unity. I’m buying a new laptop and wanted to know

[ivory bobcat]

Input only occurs during Update (old input system)
Fixed update occurs at different intervals from update and can miss events/state-changes that only occur in update

[rich adder]

not a code question

yes its good enough

[gaunt ice]

you are using vector3.up which is in the world space, so you need to use transform.up in local space and it will be affected by rotation (after translated to world space) instead of vector3.up

[fast oracle]

This just made it rotate

It kept rotating back to 0

[gaunt ice]

position+=transform.up.....

[ivory bobcat]

That would be changing your facing direction relative to up

[thorny garnet]

okay, so there are restrictions on what can occur in FixedUpdate. thanks.

[fast oracle]

I see

Thanks this got it working

[fossil drum]

Interesting, then I'm wondering what the use of disabling the Renderer and the SkinnedMeshRenderer is if they are not the same. I would think disabling 1 would be enough. I'll try it out.

[cinder plover]

I didnt even have render i only had skinned mesh but all tutorials mentioned skinnedmesh, so i just put both just in case

[swift crag]

Go back and look closely at the inspector.

It looks to me like you have a SkinnedMeshRenderer

Renderer is a parent class for many different kinds of renderers.

MeshRenderer, SkinnedMeshRenderer, TrailRenderer, LineRenderer, SpriteRenderer, and ParticleSystemRenderer, off the top of my head

If you ask for a Renderer, Unity will find the first component that you could store into a Renderer variable

since SkinnedMeshRenderer is a child of Renderer, you'll get that

If there's another Renderer component on the object, then you might get that instead

I don't see one, though.

So I would expect for this code:

myRenderer.enabled = !myRenderer.enabled;
myRenderer2.enabled = !myRenderer2.enabled;

...to turn the skinned mesh renderer off, then back on

[abstract finch]

    {
        float duration = 1.5f;
        var startRot = target.rotation; // current rotation
        for (float timer = 0; timer < duration; timer += Time.deltaTime)
        {
            target.rotation = Quaternion.Slerp(startRot, endRot, timer / duration);
            yield return 0;
        }
    }```
what does the yield return 0 in the last line actually mean?

[swift crag]

It's going to be equivalent to yield return null;.

you know how some types have a <T> in them, like List<T> ?

so List<int> is a list of integers

IEnumerator doesn't have that. It doesn't tell you what type the enumerator gives you

You can yield pretty much whatever you want

yield return "BOO!"; is completely valid

[wintry quarry]

It's the same as yield return null it just means to wait one frame

[swift crag]

Unity will look at the value and, if it's one of a small set of special types, do something with it

a WaitForSeconds will make it wait for the given duration before checking the coroutine again

I don't believe Unity has any special behavior for integers.

So it'll be just like returning a null.

[swift crag]

You might have noticed that you have these at the top of every file

[abstract finch]

so the 0 represents what exactly?

[swift crag]

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

IEnumerator isn't generic. It's from System.Collections

[swift crag]

Nothing. Unity ignores the value.

[abstract finch]

i see thanks

[swift crag]

IEnumerator<T> is generic, and it's useful for saying "this method is an enumerator for a specific kind of thing"

[abstract finch]

even though this looks cleaner is this actually better than a while loop with an if else statement?

[swift crag]

A for loop is basically just a while loop with an incrementer and a condition at the top.

for (int i = 0; i < 10; ++i)
{
  ...
}

{
  int i = 0;
  while (i < 10)
  {
    ++i;
    ...
  }
}

These two chunks are equivalent.

[ivory bobcat]

Note that timer will exit before it's equal to or greater than duration

[swift crag]

If you're in a situation where a for loop makes sense, go with the for loop

[swift crag]

Indeed. The rotation won't quite finish.

Might I suggest this instead?

float timer = 0;
while (timer < duration) {
  timer = Mathf.MoveTowards(timer, duration, Time.deltaTime);
  target.rotation = Quaternion.Slerp(startRot, endRot, timer / duration);
}

[tepid cobalt]

beep beep

[swift crag]

Although, I think Slerp is clamped anyway

so you could just do

float timer = 0;
while (timer < duration) {
  timer += Time.deltaTime;
  target.rotation = Quaternion.Slerp(startRot, endRot, timer / duration);
}

[swift crag]

This is useful because it prevents timer from ever exceeding duration

[abstract finch]

yea this is what i usually do i googled coroutine lerp unity and got that code i posted ealrier

[swift crag]

I like to use MoveTowards instead of adding + clamping

[swift crag]

and, of course, this almost neatly turns back into a for loop

but there's the tiny catch

the for loop will add to timer, then check if it's still less than duration

[swift crag]

That's why it won't quite finish the rotation.

[abstract finch]

can I ask how i could add a speed modifier to this method? I have a value called recoilSpeed

[swift crag]

You would adjust the value of duration

[ivory bobcat]

If you do the for loop approach, you'd simply need one last assignment to the expected value after the loop.

[swift crag]

I usually do it like this

float t = 0;

while (t < 1) {
  t += Time.deltaTime / duration;
  ...
}

t ranges from 0 to 1

[abstract finch]

got it im going to give it a shot because i did something like timer * recoilSpeed / duration and it bugged out

[swift crag]

well, where did you put that?

show me the code

[abstract finch]

    {
        float time = 0;
        Quaternion startRot = _transform.localRotation;
        while (time < duration)
        {
            _targetRotation = Quaternion.Lerp(startRot, targetRot, time * speed/duration);
            time += Time.deltaTime / time;
            yield return null;
        }
        _targetRotation = targetRot;
    }```

I also would like to ask if I could implement an animation curve here to ease out the speed

[swift crag]

having both speed and duration is weird

[swift crag]

and yes -- I'd suggest calculating a t value that ranges from 0 to 1, then using that to sample the animation curve

it'll remap the linear value of t into a different shape

[swift crag]

I guess duration could be an unchanging base duration, and then speed would be something that changes

Also, you're factoring speed in wrongly.

_targetRotation = Quaternion.Lerp(startRot, targetRot, time * speed/duration);

Suppose speed is 0.5

time / duration is going to range from 0 to 1

since you're running the loop until time >= duration

So on the very last iteration of the loop, let's say time equals duration

time / duration is 1.

speed * 1 is now 0.5

that's the value that goes into the lerp. the rotation will be halfway between startRot and targetRot

then the loop terminates and you snap to targetRot

[abstract finch]

thats whats happening actually

[swift crag]

speed should be used on the next line: time += Time.deltaTime * speed / duration;

oh, and that line is also wrong

time += Time.deltaTime / time;

that's going to divide by zero, since time starts out at 0

I presume you wanted to divide by duration

[abstract finch]

im testing now with the fixes you suggestedd

and its working as intended now thanks

[desert elm]

Unity keeps throwing up an error that it expects get or a set accessor in the Target = mousePos
Is this a problem that needs to be fixed or just a recommendation from unity?

[swift crag]

check your spelling.

capitalization counts!

[hexed terrace]

That VS doesn't look configured

!vs

[eternal falcon]

Visual Studio guide

If your IDE is not underlining errors in red or autocompleting code,
please configure it using the link below:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)

[swift crag]

and yes

configure your code editor.

It should be highlighting that error.

[hexed terrace]

and the method declaration

[swift crag]

I...completely glossed over that

That's why it's talking about a "get or set accessor"

public void Florp
{
  get => blorps - 3;
  set => blorps = value * 2;
}

a property might look like this

the compiler was expecting you to define get and set accessors

Whenever you see an error that talks about something being "expected", you have a syntax problem.

[static cedar]

Missing bracket errors tend to point at random stuff or drag more errors.

[swift crag]

the parser sees what looks like a property declaration, but then crashes into a value that makes no sense in a property declaration

[desert elm]

thanks for the recommendation
but I do not seem to be able to find out where the syntax problem is

[swift crag]

have you configured your code editor?

[vagrant lynx]

How should I use the parameter named x and y inside a blend tree in code ??

[swift crag]

you must have a working code editor to receive help.

[desert elm]

nvm I
didnt notice that I didnt add brackets sorry

[desert elm]

I have now yes

[swift crag]

So it's now highlighting the error?

[vagrant lynx]

I mean how to set values of the blend tree parameters from the code ??

):

[swift crag]

notice how the blend tree uses two animator parameters

[vagrant lynx]

I was watching tutorials on this but I found myself just copying what the tutorial showed and now I can't understand how they did it...... 🙂

[timber tide]

Watch it agian

[vagrant lynx]

AAAHHhh!!!

Hi! I'm currently trying to make a sort of "collectible item" in the same sort of way that coins work in the Super Mario Bros. games. for my platformer game. And of course, it doesn't work. I would really appreciate any help I can get and am willing to give any info needed

[thorn holly]

Sure, what specifically is the problem?

[thin sedge]

I did manage to make a sort of object that got destroyed when the player touched the collider, but then when I tried to get the score function to work it was like walking into a wall. Then I tried to use a sort of score version I used for another game which was a space shooter-ish thing and it didn't work either

So I'm trying to get the score to work essentially

[rich adder]

didn't work isnt very helpful, show the scripts

[thorn holly]

Can you post the code that handles the score?

[swift crag]

notably, I would like to see the code that destroys the pickup. that'll be a reasonable place to give the player some points.

[thin sedge]

Ok I'll see if i can get the code shown

[languid spire]

scoreText.text

you need to set the text property of the scoreText instance

[amber dome]

the property

text

the correct is:
scoreText.text = playerScore.ToString();

[placid wraith]

ohhhhh

crap sorry im new i see the problem

Yeah -- parameters don't apper as members of the animator

after all, all that C# knows is that you have an Animator

[sage mirage]

Hello, guys! I have a question. I want to save my options settings on my game, so when I am getting back to my main menu scene to have for example Main menu music volume to be saved. I know there is player prefs to do that but could you please give me some help for that? Check here my code

{
    public Slider mainMenuVolumeSlider;


    // Start is called before the first frame update
    void Start()
    {
        
    }

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

    public void SaveOptions()
    {
        PlayerPrefs.SetFloat("Volume", mainMenuVolumeSlider.value);
        PlayerPrefs.Save();
    }

    public void LoadOptions()
    {
        if (PlayerPrefs.HasKey("Volume"))
        {
            float Volume = PlayerPrefs.GetFloat("Volume");
            mainMenuVolumeSlider.value = Volume;
        }
    }
}```

[fossil drum]

What isn't working with this code?
Unsure what the question actually is. Seems like you know how to use player prefs to save and load stuff, so what's the problem.

[sage mirage]

Alright! I have options scene when I am entering on it and want to do some changes to my settings, I want these settings to be saved on my other scene called Main Menu Scene. Is that better?

[tulip stag]

When writing code that interacts with the gameobject that very code is attached to, what's the difference between using this.[bla bla bla] and gameObject.[bla bla bla]

[gaunt ice]

this. is not gameobject. and not interchangable most of the time

[tulip stag]

Yes, this is why I'm asking you what is the difference

[gaunt ice]

gameobject is a property while "this" is referring the instance itself

[summer stump]

This is the instance of the class (the script)

[tulip stag]

ohhhh

So for me to use this. as gameobject. I'd need to use this.gameObject.[bla bla bla]? Which would defeat the whole purpose?

[summer stump]

Just skip the this
gameObject is the gameobject attached to that script only

[tulip stag]

Yeah

Understood

[fossil drum]

Hmm, as far as I know, most people have a GameManager script and object that holds the data that all scenes use.
That GameManager is DontDestroyOnLoad and only 1 of them exists in your game, so in your Options scene you write stuff to it, and in your Main Menu Scene it still exists with the changed values where you can still call it.
You could of course do it your way of saving to preferences first, then loading the Main Scene again, and let that read the preferences again when you load the scene.

[quasi rose]

I have several tpLocation empty objects, they're all 0,0,0 for rotation. I need to sometimes subtract 5 from the x, and other times subtract 5 from the z in order to position some objects. Is there a way to make this uniform so that it's always the x or always the z (without changing gameworld)?

[gaunt ice]

cant understand, why you need to randomly subtract 5 from either x or z to position (place?) some objects? or you want to place them according to some objects?

[zenith cypress]

The two pictures and your problem aren't entirely clear of what is supposed to happen tbh. What are you trying to actually do with the positioning that makes you subtract on X or Z?

[steady isle]

how can i set an enemy's rotation to rotate towards the player

[quasi rose]

Trying to make it so that when player approaches island and dismounts vehicle, the vehicle will be repositioned directly behind where they pulled up in the water.

[quasi rose]

Trying to figure it out with Vector3.Cross. Think I can use the vehicle's transform forward and the tpLocation's, then determine if it should be -5 on x or -5 on z. Not quite sure though at the moment.

[zenith cypress]

Could you not just get the normalized direction to the boat from the point, offset by some dock amount, and position it? If not, can you show an example of the boat pulling up -> where it should end up?

[quasi rose]

Boat could pull up on island a bit (would vary somewhat), and then on dismount, player gets teleported to this location:

So I have the tpLocations all about same distance from water, hence the -5 to put boat back just a bit.

Example of another spot:

But see depending on where you arrive, the tpLocation x/z differ.

[zenith cypress]

The direction approach seems like it would work fine here. Or just rotate the tp location to face toward the water and use that to offset.

[verbal dome]

What kinda game? 2D 3D?

[steady isle]

3d

[verbal dome]

It's a pretty common thing so did you google first?

[steady isle]

sry that was unspecific

[steady isle]

no i havent

prolly should have lol

[verbal dome]

Try something then ask here if you have problems

[quasi rose]

yeah sort of got it with direction approach

thanks gotta mess with it a bit

@zenith cypress

    private void RepositionJetski(Transform tpLocation)
    {
        Vector3 offsetDirection = (tpLocation.position - transform.position).normalized;
        Vector3 newPosition = tpLocation.position + offsetDirection * -5f;
        Quaternion newRotation = Quaternion.Euler(0f, 180f, 0f);
        transform.SetPositionAndRotation(newPosition, newRotation);
    }

[zenith cypress]

Is there a reason you can't rotate the tp location btw?

[quasi rose]

When i rotate an empty nothing happens. Direction stays.

They are a child of a container that is 000

[zenith cypress]

Then you are in global space, switch to local space

[quasi rose]

woah

how many years wtf

[quasi rose]

How does that impact other stuff?

[zenith cypress]

Hm? It just shows local info in gizmos/tools

[quasi rose]

Is other code going to be borked if i was (unknowingly) relying on it to be global?

Oh ok

[steady isle]

why is the movetowards showing as an error

[solemn fractal]

hey guys, I am spawning enemies of the same type using the same prefab, but if I want to spawn a dif enemy I basically just use a scriptable object to control their dif, Hp, exp, etc.. But my prob is if I spawn enemies of the same time, lets say 4 goblins. If I hit 1 goblin and deal 2 damage it is dealing damage to all the others goblins. and not just for that object that was spawned. how can i fix that?

[zenith cypress]

So yeah you can rotate that and use the direction of that tp point to put it wherever you want it now. And can even use that direction to orient the jetski if you want.

[summer stump]

What does the error say?

Hovering over it will tell you why it's underlined

[quasi rose]

yeah this is exactly what i wanted. thanks.

[zenith cypress]

MoveTowards takes two vectors and a float. Not four floats.
https://docs.unity3d.com/ScriptReference/Vector3.MoveTowards.html

[solemn fractal]

How to fix that?

[steady isle]

no overload method for 'movetowards' takes 4 arguments

[quasi rose]

Oh i see what you mean, rather than doing:
Quaternion newRotation = Quaternion.Euler(0f, 180f, 0f); Since I guess a player may not always pull up directly straight.

[summer stump]

Yep. So when you get an error like that, first step is to look at the docs and see what overloads there are and what arguments it DOES take

Nomnom helpfully linked to them and gave you an answer here
#💻┃code-beginner message

[steady isle]

ok

[zenith cypress]

Yeah. You can now either do like jeyski.transform.forward = tpLocation.forward; or Quaternion.LookRotation(tpLocation.forward); or anything else

[quasi rose]

Gotcha, thanks ❤️

[summer stump]

To be clear. MoveTowards is a method that moves from a position to another position, and that's what the first two arguments are. So you don't separate out the x, y, and z components. You use the WHOLE vector

How would I make the colors on the left have a random pattern that doesn't repeat?
For example: Red, Green, Blue OR Blue Red Green, Etc
But never Red Red Green or any other repeating colors

put all colors in a list, take a random one. Remove that one from the List, take another one. Reset the list and remove the last color, repeat

[solid verge]

for some reason AddForce does not work on my prefab

nvm my sprite had a problem

Why does it not Instansiate my prefab at the location it's supposed to be instansiated

[fossil drum]

Your probably doing something wrong then. Can you show your code?

[solid verge]

ye hold on

public Rigidbody2D bullet;
public Transform BarrelEnd;

void Update()
{
    if (Input.GetButtonDown("Fire1"))
    {

        Instantiate(bullet, BarrelEnd.position, BarrelEnd.rotation).AddForce(BarrelEnd.right * 350f);
    }
}

maybe it's because the bullet in my prefab is place somewhere else

but that isn't the case

cause it should be moved

oh wait

nvm i don't know what to do

it only works if it's not a prefab but a gameobject

but i do not know where to hide the unused gamobject

[fossil drum]

Show the Inspector of your prefab

[solid verge]

oh

inspector

my fault

[fossil drum]

Make sure both Bullets have the position on 0, 0, 0.

[solid verge]

kinda fixed

idk i just deleted and removed some components

same as cooking just i don't burn the house on this one

anyways thanks for making me go to inspector

[fossil drum]

[steady isle]

For when i press "w", it moves me in only one direction, not forward in the way i'm facing. This is happening with "'d" for moving right, "a" for moving left, and "s" for moving back

Should i be using a different command

[eager elm]

change Vector3.forward to transform.forward

[steady isle]

for everything besides forward transform.(direction) doesnt work

[fossil drum]

Why not?

[steady isle]

im not sure

it just has an error

[fossil drum]

transform.right should be fine

[slender nymph]

well transform.left and tranform.back do not exist

[steady isle]

yea

[eager elm]

use -transform.forward for back, and -transform.right for left

[fossil drum]

-transform.right is left

[steady isle]

ohhh god it

got

ty

[solid verge]

not necessary i think

[cinder plover]

What does this error mean

[steady isle]

the thing is im tryna get it to go in the direction im facing, not just based on the x, y, and z axis

[amber dome]

• Time.deltaTime;

add this

[slender nymph]

you named the method IEnumerator instead of making that the return type

[fossil drum]

IEnumerator is a return type, replace the void with it, and give the method a name.

[eager elm]

So it's still not working correctly? Are you rotating that gameObject or how do you 'face' things?

[steady isle]

i think i might have fixed it ill respond with results and stuff in a sce

sec

[cinder plover]

Fixed that and got a new error

still the same error

[slender nymph]

you cannot add a coroutine as a listener for a unity event. create a method that actually starts the coroutine and subscribe that to the event

also your current yield is absolutely pointless since yielding only delays execution of the current coroutine

nothing prevents that coroutine from being started multiple times

[cinder plover]

Ah

[fossil drum]

Oh, mine has nothing to do with the Fire error 🤦‍♂️

[eager elm]

that entire thing is super messed up as well. The waiting doesn't do anything since nothing comes after

[steady isle]

yea so its still not working i already made it so that the camera rotates with the mouse so you can look around using your mouse, but i want it so that when i am moving it moves in the direction im facing

[solid verge]

using lookAt();?

i wanna know cause idk how to do that

or on pointerenter event?

[eager elm]

if it's the camera thats rotating than you need to get a reference to the camera and use that transform and not the transform of the gameObject, assuming they are 2 different objects

[steady isle]

yea they ar

[steady isle]

so what should i do

[eager elm]

add a reference to the camera's transform in your movement script and change transform.forward with myCamerasTransform.forward

[steady isle]

so my reference wuold be public gameObject myCamera;

[steady isle]

then i just use this

[eager elm]

no, public Transform myCamerasTransform;

[steady isle]

oh ok

[cinder plover]

Will this work?

[slender nymph]

the yield is entirely pointless. you're also not even starting the coroutine correctly anyway

[cinder plover]

ah

[steady isle]

So the movement works but now when i look down and click "s" it makes my character jump because its -forward, and in that case forward is down. The opposite of down is up so it makes me jump high. How do i fix this issue now lol

[eager elm]

tip: don't use Coroutines for now. Instead have a cooldown timer that counts down in Update(). Google: Unity Timer

[cinder plover]

kk will try

[eager elm]

I am not 100% sure, but you might be able to take transform.forward, cache it into a Vector3 variable, set the y value to 0, normalize it again and use that for your velocity.

Hey guys I want to create a way that when I hit the enemy the amount of damage that I dealt will pop up above his hear and desappear 1sec later or so. What is the best way to do this? create a child Cavas UItext? Is there a way to make it spawn a UI text everytime using instanteate or anything like that?

[minor hemlock]

I need help making a sound play when an object hits the ground

what is the code fr that?

[slender nymph]

what have you tried?

[minor hemlock]

I already have a sound that plays when the object hits the player

Im trying to make a different one

[slender nymph]

okay, so use the same logic there to play a sound when it hits the ground

[minor hemlock]

Im trying 😢

idk it just didnt work

[slender nymph]

then show what you've tried if you need help with it

[eager elm]

Vector3 fixedVelocity = myCamerasTransform.forward;
fixedVelocity.y = 0;
fixedVelocity = fixedVelocity.normalized;

rb.velocity = fixedVelocity;
//for forward

[minor hemlock]

ill try again

[verbal dome]

Yes you can do it the way you described. Optimally you would pool the UI objects, especially if you want one popup per every hit

[minor hemlock]

I followeds this weird tutorial

idk if its the best way

[verbal dome]

@solemn fractal Could use a coroutine to spawn, animate and then disable the spawned UI text

[solemn fractal]

hmm.. so I can create something like that, and use the instanteate method to instantead that to spawn it? i didnt know we could spawn also canvas things. thank you

[minor hemlock]

its just
public AudioSource audioPlayer;

[solemn fractal]

ok thank you

[minor hemlock]

if (collision.gameObject.CompareTag("Object"))

audioplayer.Play();

thats the one I used before

@slender nymph

[slender nymph]

show what you have tried for the current thing you are doing

i don't care what your other working code looks like. show the code that does not work

[steady isle]

do i do this for all direction

[eager elm]

that will cause some problems, you sometimes need more than 1 text per enemy if he gets hit twice in rapid succession. I recommend having a CombatTextController class in your scene that handles the text

[eager elm]

left and right shouldn't matter (I think)

[solemn fractal]

hmm.. and those texts I would create as a separated object cavas - Uitext instead of having it as a child of the enemy correct? Also would facilitate to use the instanteate to spawn the text above the enemy head when that happen

[steady isle]

oh ok

[raw hamlet]

for the Update function, there is a FixedUpdate that runs after Update, what is the equivalent for Start?

[slender nymph]

FixedUpdate does not run after Update

but there is Awake which happens before Start
