[shell sorrel]

so yes you want only 1 that never dies that is shared

[polar acorn]

this object should be a singleton

[reef totem]

ok

[faint sluice]

Oh my bad I missed that part

[reef totem]

so ill delete the one in scene 2 is that good

will that solve my problem?

[polar acorn]

Yes but that means you always have to start in scene 1

[reef totem]

ik

[polar acorn]

you could properly set this as a singleton so you'll be able to add it in every scene and always have one available wherever you start from

[reef totem]

ok

let me try

[shell sorrel]

really they should hit the introductory learning content and understand references better

[reef totem]

it sort of works i think

let me explain

my player is not moving

set force is equal to 2000

[shell sorrel]

well double check your player is correctly being referenced by this

since am 99% sure it is not

[polar acorn]

And does your player actually use the setForce variable from this object

[reef totem]

i think it is but the problem is foward force is 0 but setforce is 2000

[reef totem]

no

[polar acorn]

so then why are you expecting it to be using setforce when it's not using setforce

[reef totem]

because i said in my code that setforce is equal to foward force

[mossy bay]

Just started my first project with Unity and my Object doesn't jump with space bar. Can you guys find out why?
`public class birdscript : MonoBehaviour
{
public Rigidbody2D myRigibody;
public float flapstrength;
// Start is called before the first frame update
void Start()
{

}

// Update is called once per frame
void Update()
{
    if (Input.GetKeyDown(KeyCode.Space) == true)
    {
        myRigibody.velocity = Vector2.up * flapstrength;
    }

}

}
`

[polar acorn]

where and when

[rocky canyon]

i think ur trying to ride a horse after you've seen one for the first time in ur life 😄

[polar acorn]

Show the inspector of this object

[polar acorn]

Okay, so the very first frame that this object exists, you set the current PlayerScript's forward force to whatever setforce currently is

Is this object's setforce equal to 2000 on the first frame this object exists

[reef totem]

yep

[polar acorn]

are you getting an error

[reef totem]

yes

[polar acorn]

Really? How?

[mossy bay]

no. That's why I'm confused

[reef totem]

but i can quickly double check and debug it

give me a sec

[cinder crag]

anyone knows how to do this?

[polar acorn]

Show the console after you start the game and press space

[rocky canyon]

might help to assign ur rigidbody in ther

since u dont do it in code

[reef totem]

okay its not actually but i dont know why

[polar acorn]

The real question: Why do you think setforce is 2000 on the very first frame this object exists

[mossy bay]

So there is an error but I don't know how to fix it

[rocky canyon]

i just told u

[queen adder]

read the error message

[rich adder]

assign it

[reef totem]

because why not

[mossy bay]

Okay thank you guys

[rocky canyon]

drag the object with the rigidbody into the slot for the rigidbody u created

[polar acorn]

The variable myRigidbody of birdscript has not been assigned. You probably need to assign the myRigidbody variable of the birdscript script in the inspector

[rocky canyon]

the one that says None

meaning its not assigned

[reef totem]

i mean on the previous scene i set the object already to 2000 so i would expect it to stay like that

[polar acorn]

That's not how code works. It doesn't just do things for no reason

How are you setting this to 2000 before the first frame this object ever exists

Start runs on the first frame this object exists and that is the only time you set the player's force

[reef totem]

oohh u mean it like that

[polar acorn]

Yes of course I meant it like that that's why I said it

multiple times

[reef totem]

I though u meant it as the first frame this object exists in the second scene

[mossy bay]

Thank you

[mossy bay]

Thank you

[polar acorn]

I made it very very clear that this runs the first frame the object exists

[reef totem]

well doesnt void start() run every time a new scene starts

[polar acorn]

no

it runs the first frame this object exists

that's why I am very specifically using those words in that order

[rocky canyon]

no.. it doesnt run its start ever again. just the first frame it exists

ahh digi beat me to it

[reef totem]

oh i think i could get away with that since i was using 2 different objectc for 1 script but now with that ddol it doesnt work like that

ok well now that u have helped me with that

what do u suggest i do

[rocky canyon]

nope.. thast whats magic about it.. u can have ur gamemanager exist thruout the project

[polar acorn]

Use a singleton

and then have your player just use the value from the singleton directly

and not have its own copy of the variable

[reef totem]

whats a singleton

[summer stump]

https://unity.huh.how/references

[rocky canyon]

#💻┃code-beginner message

[summer stump]

Look at the singleton page

[polar acorn]

That thing I sent you a link about and told you repeatedly to use but you said you didn't want to

[reef totem]

ok

[rocky canyon]

its a script that exists (only once) can't have copies.. soo therefor u can make a reference to it. that any script can access at anytime.. anywhere

[reef totem]

but before i read it would u also reccomend i put PlayerScript.fowardForce = setforce; on a void Update

like would that also work

[rocky canyon]

why set it more than once?

why set it every frame? thats wierd

[reef totem]

yea ig

[polar acorn]

Stop trying to staple bandaids to this system and instead consider actually doing it right

[rocky canyon]

thats like me asking the time and u start counting non-stop

i'd walk away

[polar acorn]

Game Settings are kind of the poster child use case for a singleton

[reef totem]

mate chill im just asking for future reffernce im not trying to stick bandaids into anything

[polar acorn]

so read the article I linked and learn

[reef totem]

im just trying to become more familiar

[queen adder]

Yes it would work

[rocky canyon]

well, i'll suggest when u see these new words... like DDOL, additive scene loading, singleton, etc u look them up

reading about them yourself is gonna be the best way to become familiar

[reef totem]

ok

[queen adder]

Probably you shoudl learn a little bit more about C#, that would answer many of your question because they dont have anything to do with unity but more like programming

[reef totem]

anyways thanks for the help and i will update u guys soon

[rocky canyon]

good luck 🍀

[queen adder]

forwardForce is a public property that can be assigned to a certain value

[reef totem]

tbh i knew what a bunch of these things where but i quite programming for like 4 years and im trying it again but i kinda forogt everything

[rocky canyon]

should be easy to refresh urself then

[queen adder]

well, if you don't know if you can assigne a value of a property it seems that youre knowledge, regardless how many years you did this before, equals to zero 😅

so... maybe get a quick code of c# on youtube

[reef totem]

what happens if you put static in front of a variable

like what does static do

[rich adder]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/static

[night mural]

electrocutes it

think of static as meaning that thing is part of the class itself rather than a property on an instance of that class

[vocal fable]

how would you check if there's something between two objects? basically, i want to make an enemy script and if the enemy can clearly see the player the enemy follows the player

[swift crag]

use a raycast!

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

[summer stump]

Or a linecast if you're using two objects specifically

[swift crag]

or, in this case, consider using Linecast

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

A raycast shoots a ray from a point in a direction

A linecast draws a line between two points

Both look for colliders that hit the ray or line

Ah, there is a difference -- the Raycast page says it ignores colliders that you start inside of, whilst Linecast doesn't say that

I wonder if that's actually the case, though...

I should definitely be using Linecast more. I have a fair number of places that calculate a ray between two points

[timber tide]

What's the ideal setup for interface component searching in Update()? Layer masking a gameobject with a single component and interface? It shouldn't matter what this script contains beyond the interfaces, right?

I was also thinking doing it by unity tags and doing lookups.

[shell sorrel]

got more details

like what are you looking up and why

[timber tide]

Overlapsphere bunch of enemies

consistently

[shell sorrel]

oh and getting interfaces from that

really would just do it the easy way and see if you have any issues

like get your stuff and look for the component you need or interface type of what ever

if it causes a problem would then implementing some caching

[timber tide]

The script is by far the worst performant one I've got, but this ability system is kind of the main feature so it's expected.

[shell sorrel]

like for rapid fire weapons in the past i would have a dict that maps colliders to components

[rich adder]

btw overlapsphere make sure you're using the nonalloc version, the former is hella expensive

[timber tide]

Like, I have fireball abilities that hit 300+ enemies at once

every frame

[shell sorrel]

that way i am not doing constant GetComponents

[swift crag]

So you've got a persistent area of effect that's hitting tons of stuff?

[timber tide]

Yeah, my ide yells at me if I don't use them

[shell sorrel]

also for a persistient area i would use a regular collider

[rich adder]

good ide!

[swift crag]

Consider using trigger enter and exit to keep track of what is and is not being affected

[shell sorrel]

then keep track as things enter and exit

[swift crag]

jinx

[shell sorrel]

ah need a good fist bump emote

[timber tide]

that does seem smart, but say a fireball that doesn't collide but does constant damage every 0.1 seconds

and moves forward

[shell sorrel]

yeah would stil use colldier enter and exit

it does damage on its update method

[swift crag]

just make sure the fireball is moving in a way that the physics system can understand!

[shell sorrel]

and adds thigns to a hashset to do damage to

[swift crag]

so, don't set its transform directly

[shell sorrel]

and removes them on exit

[timber tide]

Sound like an idea. I do like queueing my own physics checking methods, but if that's more performant I'll look more into them

[vocal fable]

i have, the ai (basically starting point) and the player (end point)

so i should use linecast?

[summer stump]

Sure

Give it a shot

[shell sorrel]

if you are really deadset on the checksphere, would use the non alloc version, would make sure its not checking more objects then required using the masks and would create a mapping of collider to component to access that way it avoids repeated GetComponent calls

but i think the collider approach is better overall

[pallid nymph]

I tried this mapping thing once, was surprisingly not more performant than GetComponent if I have just 1-2 components... but it was a long time ago and I may have messed it up

[timber tide]

May end up throwing rigidbodies on them anyway just for the interpolation checking

[pallid nymph]

All in all, the profiler is your friend (or the Stopwatch guy)

[shell sorrel]

yeah maybe dict has too much overhead, in the case of a machine gun type weapon what i have done in the past was on first hit, save both the collider and Damageable component to fields, then on each hit, check if the collider matches first if yes skip the get component

}

alr so basically

is there a way to make it so that the things in the if statement dont happen while the things in the else if statement are happening?

[thin hollow]

why when i instantiate an object, it creates a clone?

[blazing estuary]

yes

[vocal fable]

is there an example? i think im doing something wrong, the enemy just always follows the player

[blazing estuary]

like can i make it so that it finished doing the else if statement

even if the if statement is true again

[shell sorrel]

thats already how it works

[blazing estuary]

it doesnt though

[thin hollow]

what is the (clone) item

[blazing estuary]

dunno

[shell sorrel]

then set a bool and add it to the condition

[blazing estuary]

where

[summer stump]

Fen shared the docs for linecast up above

[blazing estuary]

after the for?

[shell sorrel]

explain what you want better, with a if/if else only 1 or 0 branches of it will run at a time. if you want it to only run a branch only ever once. you set a boolean saying you run it, then check for that in the future

[blazing estuary]

so basically what i want to do is that while the else if statement is working, the if statement doesnt work even if its true again

[vocal fable]

i have this code but for some reasone the enemy moves when i am inside him???? i am clearly dumb

[shell sorrel]

so in the if else branch set something like hasRun = true

[blazing estuary]

ohh

thanks

[shell sorrel]

then in the if add a !hasRun && _distance > 10

[blazing estuary]

you saved prob hours of my life btw

thank you

[shell sorrel]

obviously use names that makes more sense for what it means to your game

but the idea of it

[blazing estuary]

yes

i have a variable called movesmth

and well it moves something i guess

[shell sorrel]

it can jsut be a field on your class
private bool _hasRun; or something like that at the top of the class

[shell sorrel]

iirc if both the start and end of a line or raycast are inside the same collider

it will not detect the hit

[summer stump]

Probably wanna use a layermask and validate what hit is.

As fen said, I believe that both the player and enemy can trigger the linecast

[vocal fable]

i did this

the enemy just always follows the player

im going mentally insane

[wintry quarry]

you're not doing anything when the linecase doesn't hit here

so if it was previously able to see the player, and now isn't hitting anything, it will continue to folow

there are basically three cases:

• Your linecast hits NOTHING
• Your linecast hits something that IS NOT the player
• Your linecast hits the player

you need to handle all three cases, not just two of them

[cinder crag]

i really need help ngl

[wintry quarry]

do you have a separate Capsule Collider from your CC?

[cinder crag]

Yeah

There's one on the playerobj and one on the emptyobj named "Player"

[wintry quarry]

you should not

there should only be the CC, not a separate capsule

[cinder crag]

oooh alrighty

the playerobj still seems to be in the same place and not come back up with the CC

and the radius seem to be skinnier for some reason

after crouch i mean

[thin hollow]

Can someone explain how to get rid of the clone object "DataManager(Clone)" that is coming from this method:

`public class MenuController : MonoBehaviour, IDataPersistence
{
[SerializeField] private List<GameObject> persistentObjectList = new List<GameObject>();
[SerializeField] private List<string> persistentNames = new List<string>();

public static DataPersistenceManager dm;


private void Awake()
{
    if (GameObject.Find("DataManager") == null)
    {
        GameObject newDm = new GameObject();
        
        newDm.name = "DataManager";
        newDm.AddComponent<DataPersistenceManager>();
        newDm.GetComponent<DataPersistenceManager>().GetInstance().SetFileName("game_data.json");
        Instantiate(newDm);
        
    }
    else 
    {
        GameObject temp = GameObject.Find("DataManager");
        dm = temp.GetComponent<DataPersistenceManager>().GetInstance();
    }
    
}`

[shell sorrel]

why Instantiate if you dont want a instance of it then?

[short hazel]

The Instantiate(newDm) is what's doing it

Instantiate creates a copy of the object you pass to it

[thin hollow]

basically i want to check the scene is there is a datamanager

then if there isnt, create one

[polar acorn]

If you don't want to clone it why are you cloning it

[short hazel]

Doing new GameObject() already creates the object in the scene for you

[thin hollow]

ohhhh

i didnt know that lol

i thought it was just in memory and not in the scene

[cinder crag]

i still need help with this please , i was jsut following this tutorial https://youtu.be/-XNm7dPVVOQ?si=2T1G51VgZE91fn3e

[polar acorn]

You never change the center back to 0,0,0

You've cropped those out of your video, what are those set to in the inspector

[cinder crag]

oh my god , it was 2f and not 0 😭

these type of mistakes are the death of me

[polar acorn]

It's also serialized so the value in the code doesn't matter, what is it in the inspector

[cinder crag]

i put it to 0 dw

it works nice now so thats good

now how do i shrink the player when crouching and then the player grows back up , i already tried these

[polar acorn]

That should work but it's instant, you're not doing any sort of smoothing on that, which means you can probably take it out of the loop

[cinder crag]

Which one of the pics should work tho

[polar acorn]

Do you want a condition or not

[cinder crag]

Does it matter if it's a condition or not?

[polar acorn]

I literally cannot answer this

Do you want it to be conditional or not

[cinder crag]

Nope

[polar acorn]

This is not a "good code bad code" thing this is literally "what do you want the code to do"

If you don't want to conditionally change the height, then don't change the height conditionally

[thorn holly]

If a kinematic and static body collide, will OnCollisionEnter be called?

[polar acorn]

https://docs.unity3d.com/Manual/collider-types-interaction.html

[thorn holly]

Thanks!

[thorn holly]

Darn, that creates an issue, I have something that I need to manipulate like a kinematic body (only explicit movements, no physics simulation), but also doesn’t go through a static body

[polar acorn]

Then you'll need to slap a rigidbody on the other thing

[thorn holly]

On the static body?

[polar acorn]

The non-kinematic one will need to have a rigidbody on it as well. If you're in 2D I think that rigidbody specifically needs to be "dynamic" but in 3D a "static body" is just a collider with no rigidbody

[thorn holly]

Is there a way to stop all of the physics simulation from occurring on the dynamic rigidbody? I need it to be able to collide/not go through other physics bodies, but nothing else

[polar acorn]

You could try freezing all position constraints

[thorn holly]

That would work. So if I have a wall and a ball that would bounce off it, but neither do physics simulation, I make the wall a dynamic rigidbody, freeze position contraints, then make the ball a kinematic body?

[polar acorn]

Possible.

[thorn holly]

Will do, thanks

[pallid nymph]

how would the ball bounce?

if it's not doing physics sim

[polar acorn]

[minor patio]

so I'm trying my hand at a character creator app for a table-top rpg and I'm trying to deal with abilities ("Competencies & Specialisations") - I've got an issue where my list of Competencies is being called multiple times (the list is initialised in an Awake method) & I can't think of how to debug it. I've got another issue where the competency variable is supposed to be 'got' from the list index, but my debugs are generating Null Reference Exceptions on the variable and I again can't figure out how to check for the variable having an assigned value. Not posting code until I'm asked for it Any insight welcome

[polar acorn]

Show code

And show the specific error

[cinder crag]

I simply just want the player scale to shrink to 0.5 and then go back to the normal scale

[polar acorn]

So do what you're currently doing to change the Character Controller height, but change the scale instead

[cinder crag]

The scale of the playerobj , right?

[polar acorn]

If that's what you want to change the scale of yes

[cinder crag]

Alrighty then

[summer wasp]

how can i make arrow point towards the velocity direction? considering its face is not the arrow tip

[polar acorn]

So, line 128 is a curly brace. Is that the most recent error? Clear the console and run it again, what line does it show the error is on?

[polar acorn]

You can set transform.foward, transform.right, or transform.up to a direction and it'll rotate the object in that direction. Find out which direction of the object you want to face "forward" and set that direction to the velocity direction

[minor patio]

https://i.imgur.com/YbH0H7G.png
I hope this helps

[polar acorn]

So, if the error still says line 128, either you're missing something from the bin or you haven't saved a change because that line doesn't have anything on it

[summer wasp]

i would need to multiply rb.velocity with transform.up?

[polar acorn]

As I said, you can just set one of those direction vectors to velocity and it'll point that vector in that direction

[summer wasp]

i didnt get it

sorry about my grammar

[polar acorn]

Which direction of the arrow do you want to point in the direction of velocity

it's the debug line itself - if I use 'competencyTitle' by itself the code runs fine, but the debug logs have a blank space where the title should be

[summer wasp]

the tip

i dont know exactly how to explain

[polar acorn]

Is that Up, down, left, right, forward, or backward

[summer wasp]

up

[polar acorn]

Then set transform.up to velocity

[polar acorn]

So competency is null which means there's a null in the list somewhere. The list is public (and static) meaning it can have an element added to it from anywhere and the issue might not be in this script. Try logging the index and competency as you get it in the loop

[summer wasp]

is there a way to make it turn a little more smoother?

[polar acorn]

Instead of setting it to the value, Slerp it towards the value
https://docs.unity3d.com/ScriptReference/Vector3.Slerp.html

[summer wasp]

ooh thanks

[minor patio]

"Try logging the index and competency as you get it in the loop"
There's a loop?!? A sound suggestion, tho

[polar acorn]

Sorry, the if statement. I lost Internet on my PC so I'm on mobile and it's difficult to switch back and forth

Although looping over it and printing them all would be a good debugging step

[thin hollow]

int he editor for sprite renderer, is "Order in layer" the same as <SpriteRenderer>().sortingOrder

[polar acorn]

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

[minor patio]

bummer about your connection - it be like that sometimes
a debug returning the index works, returning 0 - but the competency.competencyTitle still returns void

[polar acorn]

So that'd mean that the first thing added to this list is null

In Awake, add this:

foreach(Competency c in competencies){
  Debug.Log(c);
}

See if anything's in it before you add all the other stuff in awake

[minor patio]

gotcha

[minor patio]

oh, dear - that's a lot of null XD

[polar acorn]

So, something is adding in a bunch of nulls before any instances of this script are added

look for other scripts that reference the competencies list

Wait, hang on a tick:

Why is your competency object a child object of your Competencies list

Competencies is a Monobehaviour, you can't create instances of it with new

You should have been getting a ton of warnings about that

[minor patio]

you'd think so, but no

[polar acorn]

Can you send a screenshot of your full console, including the bit at the top and the scroll bar

[minor patio]

the full console generates 720-odd reaferences by the time I reach the relevant debugs, but sure

https://i.imgur.com/Bnwe3az.png
more, or less?

[polar acorn]

Hm, there should definitely be warnings about creating a MonoBehaviour with new. Still, there's zero reason for your Competency objects to extend Competencies. You can't create them with new, so you're going to get null out of it

[minor patio]

yeah, I think I see what you're getting at...

[minor patio]

so I changed the code to make the Competency child class redundant, but I'm still getting null for my debugging c
As Tank Girl so elegantly said "this might take me a really long time"

[polar acorn]

So is Comptency no longer a MonoBehaviour

[minor patio]

as I said, Competency is no longer an issue; I'm working with Competencies only
I commented out the Competency class

[polar acorn]

Then what is the list of

[minor patio]

the list is now a list of Competencies - there's no child class of Competency anymore

not that that's helping me...

[shell sorrel]

that is confusing naming

[teal viper]

You'd think it's plural of the same object

[polar acorn]

why

[shell sorrel]

generaly if giving something a plural name, it will be for a collection

or a object that contains many of something

[polar acorn]

Why does this object contain a list of itself

How are you adding itself to the list since you can't create itself with new

[minor patio]

...you think I shoulda stuck with the child class?

[polar acorn]

What do you want this list to contain

[minor patio]

I would like the list to be a list of skills that a character can acquire
I want this list to contain functional code XD

[polar acorn]

Okay, so what is a skill that a character can aquire

what represents that concept in your code

[shell sorrel]

so want each one to be able to define some functions?

[minor patio]

I'd hazard a guess & say that the skill a character can acquire is an object..?

[polar acorn]

I dunno. You tell me

[minor patio]

yeh

[polar acorn]

Is it a GameObject, a ScriptableObject, a string, a POCO, an enum

it can be a lot of things

[shell sorrel]

also how much stuff is the same between skills

[minor patio]

wtf is a POCO?
sorry, I'm still fresh out of noob-school

[shell sorrel]

just a regular C# object

[polar acorn]

Plain Ol' C# Object

[shell sorrel]

not a monobehaviour

[polar acorn]

As in not inheriting from anything, just a class with data and maybe some functions

[shell sorrel]

how much do skills have in common vs not in common

[minor patio]

more not in common than in common, from my experience
not to say that they have nothing in common...

[shell sorrel]

so make a base class that repersents the most generic version of a skill

then have other classes extend from it, for the more concreat versions of the skills

that can override methods

[minor patio]

that would be my Competency class

[minor patio]

kinda what I had in mind

I need a break - thanks for your input, @shell sorrel , @polar acorn

"You've given me a lot to think about" XD

[shell sorrel]

its always good to take breaks, gives you time to think about stuff in the back of the mind

[minor patio]

😉

later

[thin hollow]

how to I reference this aka add a new item to this in event trigger via script

[polar acorn]

https://docs.unity3d.com/ScriptReference/Events.UnityEvent.AddListener.html

yes

[meager raptor]

purpose: when unit health reaches 0, it should get destroyed

error: as soon as i start the game, literally all the units get destroyed aka the game objects get deleted. does anyone know why this is happening?

[timber tide]

debug.log everywhere you set health

[meager raptor]

^ as soon as i start the game

its happening to both player n enemy units

idk where the problem is

[timber tide]

if you want to post the script on a pastebin site, go for it because there's nothing here that shows you setting the health

[meager raptor]

wait i kinda found the error still need help tho

problem is, base health has values but when game starts the current health is still 0, it should be equal to base health

what's the solution for this?

[timber tide]

time to debug baseStats.health then

it's less likely an editor error and more that you're setting it incorrectly in your code

[meager raptor]

not sure if this part of the code is the problem but i'll just put it here anyway

[timber tide]

so your baseStats is a scriptable object, where are you referencing it and how are you using it

[meager raptor]

here

[timber tide]

right, but you aren't setting baseStats.health at all right? You're just serializing it to the script and using that exact instance?

[meager raptor]

yeah i set it in the unity program

like this

[timber tide]

I don't see where you're creating an instance of base though

oh, that could be a problem

just to test something, remove everything from Base and put it directly into UnitStatTypes

otherwise, create an instance of Base inside of UnitStatTypes

and serialize that

[warped vale]

help please

[timber tide]

public class UnitStatTypes : Scriptableobject
{
    [field: SerializeField] public Base BaseData { get; private set; }

    [Serializable]
    public class Base
    {
      [field: SerializeField] public float health { get; private set; }
    }
}```

[warped vale]

what do i do with that

[rocky canyon]

whats this doing there?

[warped vale]

its a multiplayer package

[summer stump]

Beat me to it. Remove that

[rocky canyon]

thats wrong.. the syntax is wrong

[warped vale]

its multiplayer

[meager raptor]

thanks, what's next

[rocky canyon]

doesnt matter... its written wrong..

[summer stump]

Yes but randomly writing the name of the muliplayer package doesn't make sense

[summer stump]

We know. Photon is very popular

[timber tide]

debug the health that it's set in start

[summer stump]

But that is not how you use it

[teal viper]

What does it matter? It being multiplayer package doesn't change C# syntax

[rocky canyon]

namespace Photon.VR
{
  [CustomEditor...

there shouldnt be random text between two opening brackets like that

[warped vale]

like this?

[summer stump]

No

[rocky canyon]

now ur brackets missing..

[summer stump]

Just the word photon needed to be removed

You should... probably learn c# before attempting multiplayer

[meager raptor]

gettin these errors can u refine the code u made a bit

[teal viper]

I super highly strongly recommend to stop right there and do some C# basics learning before even thinking about multiplayer.

[warped vale]

alr

[teal viper]

If you keep doing what you do with your current level, not only you're gonna fail, but people would refuse to help you too.

[rocky canyon]

using UnityEditor;
using UnityEngine;

namespace Photon.VR
{
    [CustomEditor(typeof(PhotonVRManager))]
    class PhotonVRManagerGUI : Editor
    {
        private Texture2D logo;
    }
}```

make sense??

[timber tide]

my code is fine, if you've more variables add them or hide them for now

[warped vale]

ya

[rocky canyon]

I'm always trying to beat u to the punch... u always sooo fast >8)

[warped vale]

now this showed up

[warped vale]

ik

[teal viper]

I guess you didn't listen to what I said...

[warped vale]

😔

[rocky canyon]

it can't find Pun in the namespace ur using..

why? idk

[meager raptor]

same error

[timber tide]

Wherever you're setting the SO can you write this:

public UnitStatTypes statTypes;

public void Start()
{
  Debug.Log("Health is: " + statTypes.BaseData.health);
}```

[meager raptor]

yeah 1 sec i have to amend the code

[timber tide]

there's a reason I've got private setters there

[meager raptor]

yeah but then i get these small errors x5

[summer stump]

Well what is baseStats?

I saw baseData in mao's code

[timber tide]

you're missing an accessor

my code creates/requires one more dot operator

[meager raptor]

how would you amend this?

[timber tide]

Dont return by UnitStatTypes, just send the full reference

oh ok you're writing to the SO it seems?

[meager raptor]

yeah

appreciate the help btw

[timber tide]

im guessing you were just writing to a single instance of an SO and reusing that single instance everywhere

[meager raptor]

👍

[timber tide]

so why exactly are you setting the stats in the inspector, but then set them to another value in code?

[meager raptor]

wait no im not tryna do that im just setting em in the inspector and then making another variable and setting the current health as the base health when booting the game

currentHealth = baseStats.health; ```
just like this

that's the aim anyway but it doesnt seem to be working

[timber tide]

Set the return type to just UnitStatTypes for GetUnitStats

[meager raptor]

okay, still with the code u provided above?

[timber tide]

yeah

then change your PlayerUnit to have a field of UnitStatTypes

instead of Base

so this way they get the instance of the SO instead of just the nested class

[meager raptor]

gotcha, what am I replacing in the red swiggles

[timber tide]

basically, serialization issues with the nested class and you're trying to access it directly instead of using the actual instance of the SO (or rather you're creating independent instances of the inner class? idk but you shouldn't need to reference by these inner classes)

so if unit has Base instance it needs a UnitStatTypes instance

[meager raptor]

ah okay

[cosmic dagger]

does it need to be a nested class of an SO?

[meager raptor]

its 2am rn gotta wake up at 8 so ima go now but i appreciate the help and ill let u know once i solve so u wont be left hanging @timber tide thanks for the help

[timber tide]

probably not for their requirements but I just wanted to show a better way to serialize it if that was the problem

[thin hollow]

how do I make 2 seperate events, right now im getting the hover and down function when i mouse hover

public void AddEventData(GameObject newObj)
{
    List<EventTrigger.Entry> events = new List<EventTrigger.Entry>();
    newObj.AddComponent<EventTrigger>();
    EventTrigger trigger = newObj.GetComponent<EventTrigger>();
    EventTrigger.Entry entry1 = new EventTrigger.Entry();
    EventTrigger.Entry entry2 = new EventTrigger.Entry();
    events.Add(entry1);
    events.Add(entry2);

    entry1.eventID = EventTriggerType.PointerEnter;
    entry2.eventID = EventTriggerType.PointerDown;

    entry1.callback.AddListener((data) => { OnPointerEnterDelegate((PointerEventData)data); });
    entry1.callback.AddListener((data) => { OnPointerDownDelegate((PointerEventData)data); });

    
    foreach (EventTrigger.Entry e in events) 
    {
        trigger.triggers.Add(e);
    }
    
}

public void OnPointerEnterDelegate(PointerEventData data)
{
    Debug.Log("OnPointerDownDelegate called.");

    selectorController.Hover();
}

public void OnPointerDownDelegate(PointerEventData data)
{
    Debug.Log("OnPointerSelectDelegate called.");

    selectorController.Select();
}

[ivory bobcat]

Are you sure you want to be adding both delagates to the same event entry?

[thin hollow]

im not sure how it works

[ivory bobcat]

Right now you're adding them both to entry1

[thin hollow]

ohhh

ok

[nimble apex]

      if (result == 1 && bacResult.banker == 6 && history.bac_type == int.Parse(BacOption.nonCommision))

        else
        {
          text.fontSize = 36;
        }
      }```

this code has a "invalid AABB in AABB" error

and that error wont even tell me why and whats wrong

[teal viper]

What line?

[nimble apex]

this is the error, very special, no stacktrace at all

thats all of it

and because of that, the function has broken

i know where it is just because it happened after i made the code above

[timber tide]

time to use the debugger

and break point it

[teal viper]

It's coming from a scroll rect. Does that give any clues? Anything in that code related to scroll rect?

[nimble apex]

not at all, the UI with this script doesnt even have a scroll rect

and all related base class and subclasses dont even involved in doing scroll rects

[teal viper]

Do you have a UI that does have it?

[nimble apex]

btw, restart wont fix that

[twilit pilot]

I've been plagued by this before in a UI-heavy game, it's a very unhelpful error message - disabling/enabling UI elements at runtime can help locate what's causing it

[nimble apex]

can you ignore or suppress this warning?

[timber tide]

I usually see it when my elements invert into themselves

or become 0

[nimble apex]

this doesnt make sense in my case, because all i added is just a boolean to the code

and that boolean is checking a server data (integer) , and comparing it with an enum

[twilit pilot]

the times I've had it, it's been some scroll rect/UI element set to a width of -0.0008 or something silly

[nimble apex]

before i added that boolean, everything works fine

yo WTF

git sourcetree has new commit

[teal viper]

Finding the scroll rect that causes the error would be the first step to fixing it.

[nimble apex]

aight

ok sry guys

maybe its the commit?

[teal viper]

Maybe.🤷‍♂️

[nimble apex]

the commit has a change in one of the main UI

nope

that commit doesnt even do anything

i reverted or pulled the changes , both not working

i gonna delete the boolean, to see if a checking of an integer really screw this up

ok

cant

[teal viper]

You don't just check bool/int though, you set sprite, text and font size. All of these could be related.

[nimble apex]

the error happened only 20 min ago, the changes of the sourcetree might be the biggest suspect

because the UI it changes are the parent of this one

and that change commited 10 min ago

[teal viper]

Well, ui elements can affect each other depending on the setup.

So, even small changes like adding text, could be affecting elements on the other side of the canvas.

[potent nymph]

I'm in a situation where I have to use NuGet to install a package for a Unity project. I've never used the package manager before, and I'm confused as to what checkbox I need to tick to install the package

If I don't have anything checked, it won't let me install it. Do I have to check everything (Project)?

[uncut shard]

My capsule flickers and shakes when it goes on the side

This code tells me :
Error CS1061 'GameObject[]' does not contain a definition for 'GetComponent' and no accessible extension method 'GetComponent' accepting a first argument of type 'GameObject[]' could be found (are you missing a using directive or an assembly reference?)

Not sure what this is telling me. I've used GetComponent often and never ran into an error like this.

[wintry quarry]

Read it carefully

You're trying to call GetComponent on an array

Which naturally doesn't make much sense

[indigo python]

I'm following a tutorial and this is the exact code he wrote and worked though. Hmm

[wintry quarry]

It's not

You wrote it wrong

You used the plural version of FindGameObjectsWithTag

[nimble apex]

god dammit , found it

pretty horrifying

[cosmic dagger]

👀 scary . . .

[foggy lion]

I'm using coroutines to time movement between transform.Translate, but when I stop it upon colliding with ground, it moves once more before stopping, code below.

using System.Collections.Generic;
using UnityEngine;

public class FallingBlocksScript : MonoBehaviour
{
    public bool DoneMoving;
    public bool CanMove = true;
    public float BlockFallDelay = 2.0f;
    // Start is called before the first frame update
    void Start()
    {
        StartCoroutine(FallDelay(0.0f));
        CanMove = true;
    }

    void OnCollisionEnter2D(Collision2D collision)
    {
        if (collision.gameObject.tag == "Ground")
        {
            CanMove = false;
            Debug.Log("BlockTouchingGround");
            StopCoroutine(FallDelay(0.0f));
        }
    }

    IEnumerator FallDelay(float v)
    {   
        if (CanMove == true)
        {
            yield return new WaitForSeconds(BlockFallDelay);
            transform.Translate(0, -0.5f, 0, Space.World);
            StartCoroutine(FallDelay(0.1f));
        }
    }
}```

I can provide a video if needed

[rich adder]

well yeah you start a new coroutine

[cosmic dagger]

you have a parameter for the coroutine, but it's not used within the method. also, you start the same coroutine with a different value for the parameter inside of the coroutine . . .

[rich adder]

You should store it in a variable of type Coroutine if you want to stop coroutine

[foggy lion]

Alright

[nimble apex]

so theres a checking being faulty, resulting a variable become 0

the width and the posx of the UI depend on this variable

[indigo python]

ty

[nimble apex]

so if posx or width / 0 , they become infinite

[foggy lion]

Although I thought it should be stopped as soon as it touches the collider because of StopCoroutine?

[rich adder]

You have to store it inside a variable to stop it, otherwise it doesn't know which to stop.
You can do either IEnumerator or Coroutine.

[teal viper]

Dividing by 0 is bad obviously

[rich adder]

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

[nimble apex]

    boxWidth = ((m_BGRectTransform.rect.width - 10 * 2) / m_columnNum) - 3;
    winnerHighlightWidth = boxWidth + 20;```

m_columnNum is 0 , because bool failed

[teal viper]

Maybe use a Max with (1, m_columnNum), to avoid this kind of situations. Or just don't set the width at all if it fails.

[nimble apex]

    {
      m_columnNum = m_betDetails.GetComponent<BacBetDetails>().m_columnNum;
    }
    else
    {
      Debug.LogError("m_columnNum error! value cannot be 0");
    }
``` i gonna pop an error instead

so i know whats wrong

ok ty

[foggy lion]

Am I doing it right?

using System.Collections.Generic;
using Unity.VisualScripting;
using UnityEngine;

public class FallingBlocksScript : MonoBehaviour
{
    public bool DoneMoving;
    public bool CanMove = true;
    public float BlockFallDelay = 2.0f;

    private IEnumerator crouton;

    // Start is called before the first frame update
    void Start()
    {
        CanMove = true;
        crouton = FallDelay(BlockFallDelay);
        StartCoroutine(crouton);
    }

    void OnCollisionEnter2D(Collision2D collision)
    {
        if (collision.gameObject.tag == "Ground")
        {
            CanMove = false;
            Debug.Log("BlockTouchingGround");
            StopCoroutine(crouton);
        }
    }

            StartCoroutine(crouton);
        }
    }
}```

[rich adder]

nope

[foggy lion]

Damn

Man, this is confusing...

or maybe I'm just dumb

[rich adder]

its in the docs how you do it..

did you even read what I sent?

[foggy lion]

Yes

And I thought I followed it correctly

[rich adder]

wait nvm u did it in start

[nimble apex]

normally i wont cache it into a variable, i will just call it like a function with startcoroutine ,

[rich adder]

wdym

[nimble apex]

do it directly like this

[rich adder]

how do you stop it then

doesn't have to be endless, you can stop if something is taking 7 seconds but you want to interrupt in 3

oh nvm your msg disappeared lol now minelooks out of context

[nimble apex]

dw im here , thats enough lol forget about the disappeared text

[cosmic dagger]

don't worry, i seen it. i'll vouch for you . . . 😆

[rich adder]

so what's happening now instead?

you forgot to assign it again to StartCoroutine(crouton); in FallDelay

[foggy lion]

I ended up rewriting it a bit differently and it just seems to be working

using UnityEngine;

public class FallingBlocksScript : MonoBehaviour
{
    public bool CanMove = true;
    public float BlockFallDelay = 2.0f;
    public float BlockFallDistance = 0.5f; 

    private Coroutine fallingCoroutine;

    // Start is called before the first frame update
    void Start()
    {
        fallingCoroutine = StartCoroutine(FallRoutine());
    }

    void OnCollisionEnter2D(Collision2D collision)
    {
        if (collision.gameObject.tag == "Ground")
        {
            CanMove = false;
            Debug.Log("BlockTouchingGround");
            StopCoroutine(fallingCoroutine);
        }
    }

    IEnumerator FallRoutine()
    {
        while (CanMove)
        {
            yield return new WaitForSeconds(BlockFallDelay);
            transform.Translate(0, -BlockFallDistance, 0, Space.World);
        }
    }

    private void Awake() 
    {
        CanMove = true;
    }
}```

[rich adder]

seems fine, though if you have a rigidbody you should prob use its movements not translate

also instead of == tag use .CompareTag()

[foggy lion]

I should, but I won't lie, it works therefore I will not touch it if it breaks again.

[foggy lion]

Is it faster?

[rich adder]

much

[foggy lion]

Alright, I'll do that at least lol

Thanks for the help

[summer stump]

What is happening here? This is so out of context!

[vale karma]

https://paste.ofcode.org/U5aPjSGbmNLeVQ2BwWqy6J
Hello again, im getting this error from Unity. I followed an inventory system tutorial that was really well documented. I checked line for line for anything different, and he also had serialization and save issues, but at the end he solved his issues, but I got this issue he didnt have.

[thin hollow]

anyone help me with Lerp within coroutine, i dont get why its not working:

{
    Debug.Log("Lerp");
    startPos = obj.transform.position;
    Vector3 target = new Vector3(4f, 8f, -1f);
    float timeElapsed = 0;
    float totalLerpTime = 5;

   
    
   
    while (timeElapsed < totalLerpTime)
    {
        obj.transform.position = Vector3.Lerp(startPos, target, (elapsedTime/ speed));
        timeElapsed += Time.deltaTime;

        yield return new WaitForEndOfFrame();
    }

    Debug.Log(obj.transform.position);
}

[vale karma]

nvmd i forgot to add a file save path for my equipment inventory

[cosmic dagger]

why are you dividing elapsedTime by speed? that is not one of the variables created within the coroutine . . .

to get a percentage, you divide the current value by the total value . . .

[thin hollow]

ah

i missed that

thank you!

[cosmic dagger]

speed — in this context — does not appear to be the total value. we don't even know what it is set to . . .

[thin hollow]

but even changing that to totalLerpTIme it still doesnt work

[cosmic dagger]

also, set the position to target after the while loop to ensure it's at the final position, because when timeElapsed is not less than totalLerpTime, it will not run the code to set it to target . . .

do you need to WaitForEndOfFrame? using null will wait until the next frame . . .

[thin hollow]

i dont think it matters

[cosmic dagger]

do both of the logs appear?

[thin hollow]

yes

[cosmic dagger]

within the while loop, log the elapsedTime or the position to see if the values update . . .

[thin hollow]

elapsed timeis working

but it isnt changing position

[cosmic dagger]

then you need to check startPos and target . . .

or make sure you're updating the correct GameObject . . .

[thin hollow]

i mean it looks all good

so is the second parameter in Vector3.Lerp the final position you want to get to?

ah fuck

i think i used the wrong variable

[cosmic dagger]

yes . . .

[thin hollow]

i got it

ty for the help!!

[cosmic dagger]

it doesn't matter if it looks good. it needs to be correct and work properly. always check every variable used. the program will do exactly what you tell it you. never guess, always confirm . . .

Hi there, I am currently making a tile based game where the player's movement is discrete, which means that the player will move from (0,0) to (0,1) instantly, without going through any decimal points and stuff. Since this is the case, collision detection must be done manually whenever the user gives an input for the player to move in game, and I have a question regarding this:

Question
What is the best way to implement this kind of tile based system where data and information about the block can be accessed easily without too much spaghetti?

My Current Approach
I created a new monobehavior class called "Tile" that stores data about the tiles (like isMovable, isInteractable,tileType etc..), and stuck that on my different tile gameobjects, and in a manager, there would be a long if else just to identify the object (which, of course, is definitely not the best method, and the brains in my braincells really hate it), then, I would create a large 100x100 Tile 2d array to store all the tiles (this was created based on the assumption that my game level will not exceed the 100x100 range).

My small idea
Use inheritance child classes to store the different required data on the tiles, and retrieving them would be quite nice. However, the problem is that, since my array is an array of tiles, so I can only get the tile class, cant really get the child classes and their properties

Any help about this matter is really really appreciated! (I have been losing my mind concerning this problem for the past 4 days and I haven't found a solution myself by experimenting, or searching through the internet). Thanks!

[teal viper]

Ideally, you wouldn't need to get the child class. You'd use polymorphism to define different behavior for different tile types. In your manager you'd just need to check tile.IsWalkable or something

But if you really want to, you can cast the base type to the desired type and if it's not null, you would be able to access the child class properties

[potent nymph]

this is a Unity port of a package that I need for my project, but I'm unsure how to download it to include in my project. Usually I'm used putting the git url in the package manager or downloading a unitypackage file, but this repository doesn't have any of those https://github.com/WulfMarius/NAudio-Unity.git

I tried downloading the zip and putting the files into my assets folder, but that resulted in namespace errors everywhere

[robust prism]

ah, so can I assume that I will need to still include those if else to do the collision detection stuff, but I can use polymorphism to change the properties of the tile individually in those child class, and access the already existing properties from the base class tile?

[tough lagoon]

https://github.com/WulfMarius/NAudio-Unity/releases

Looks like its for modding unity games, not unity game development

[potent nymph]

I see, that's a shame

I used the main NAudio package, which worked in editor but webgl builds don't support dlls

[hot wave]

how to make box collider be the same shape as mesh?

[queen adder]

use mesh collider

[faint sluice]

There's an option to resize collider

[faint sluice]

Wouldn't recommend it if it got lots of polygons

For most use cases using simple colliders is preferable

[queen adder]

what they want, what you give, it's not that bad anyways

[hot wave]

thank you yappy, sexy I was using a low poly for mesh

[teal viper]

Not sure I understand your intention correctly. Maybe sharing some code would be helpful.

[robust prism]

ahh, I'm currently outside now, maybe I'll ping you when I get back home, is that alright? Thanks for your help!

[teal viper]

It's fine, but I might not be available at that time, so it's better to just ask your question again and provide more details(like code).

[robust prism]

ok!

[vale karma]

is there correlation between the animation/animator and a Movement State machine? I want to start implementing some animations, but im worried how ill implement it into my state machine

[noble forum]

hi, anyone knows why OnMouseDown() doesnt work for me? it does nothing when i click on object with box collider (3d unity)

[vale karma]

whats the code look like for that method?

[stuck jay]

Send the code

public class Card : MonoBehaviour
{
    private CardGameManager gm;
    public int handIndex;
    public bool HasBeenChecked = false;

        BackButton.SetActive(false);
    }

    public void PlayCard()
    {
        // Different outcome for every card


        Invoke("MoveToDiscard", 2f);
    }

    public void MoveToDiscard()
    {
        gm.discardPile.Add(this);
        gameObject.SetActive(false);
    }
}``` not finished one, but this function should work

[stuck jay]

Does Debug.Log("Card clicked!" work?

[noble forum]

no

[stuck jay]

PlayButton and BackButton weren't set

Look at the script on the object

[noble forum]

i know

it doesnt matter

[stuck jay]

Actually yeah, that's weird

[noble forum]

im not finished with the script yet, but it has no effect on clicking

[stuck jay]

OnMouseDown is called when the user has pressed the mouse button while over the Collider.

[noble forum]

i know

[languid spire]

Not 100% sure but you may need to add a Physics Raycaster to your camera

[noble forum]

i can click on buttons

[languid spire]

but buttons are UI objects, your Card is not

[noble forum]

doesnt work

[languid spire]

Is the event system recognising your card?

[hot wave]

can I use hit.transform instead of hit.collider?

or different uses

confused because different tutorials uses different things, but I want to fuse the functions

[north scroll]

hey im trying to create a character controller, currently the player moves up and down as well even though there are no key binds for it. I want to limit the movement to only move left and right, and i tried accessing the x value of the readvalue but doesnt work

[teal viper]

You can use whatever makes sense in the context of your use case.

[languid spire]

why would you not just set the y component of move to zero?

[north scroll]

wouldnt that affect the jump of im continiously setting Y to 0 and I add a jump button / function ?

[languid spire]

yes, of course, so you would need to do that conditionally

[north scroll]

so like if jump button not pressed, y = 0 ?

!OnJump()

im using new input system btw

[languid spire]

Not really. it will depend how you code your jump logic, will Input[move] play a role in that?

[north scroll]

i dont think so. I plan on using addforce, I think thats the most straightforward way

and limiting it to one jump so its not spammable and add too much force

[noble forum]

Ill answer later, i had to chase the bus lol. I think ill just have enough and make every card a button with the same function lol.

[languid spire]

then always setting move y to zero will have no effect on your jump as it is merely zeroing out the input from the Move action

[north scroll]

would it be better if I use AddForce instead for everything and just set a cap of how high the addforce can go ?

that way if I continiously hold the analog stick it doesnt endlessly get faster

[languid spire]

you dont need to do that. you can try using the IPointer interfaces or add an OnClick Event

[languid spire]

that depends entirely of the mechanic you are trying to implement, this is why making character controllers should only be done by people who know what they are doing

[north scroll]

:(

[noble forum]

Ill answer when i will start unity on school PC lol

[faint sluice]

Is there a way to detect when user has clicked mouse, without using update?
(Click doesn't have to be necessarily on the gameObject with script attached)

[languid spire]

https://docs.unity3d.com/2019.1/Documentation/ScriptReference/EventSystems.EventTrigger.html

[faint sluice]

Doesn't event triggers only respond when you click on the gameObject that has the script?

[languid spire]

tbh I've not used this for a while, I seem to remember that if you attach the script to the EventSystem then it will pick up everything

[north scroll]

my jump method makes my character jump immediately, I tried Forcemode2D.Impulse, but that doesnt apply any up force to the character.

[icy junco]

what would be best networking for an fps multiplayer?

[teal viper]

One that you implemented yourself.

[icy junco]

what do you mean?

[teal viper]

Exactly what is sounds like.

[icy junco]

so a server that you setup yourself?

[teal viper]

Server, or peer to peer setup. Depends on what you need.

[icy junco]

allright so better setup a server then just using fishnet or photon

[teal viper]

If you can do it and the time and effort is worth it, sure.

[icy junco]

so when setting up a server do you need like a regular old computer to make it ?

[teal viper]

No... It depends a lot on how you're connected to the internet(provider), the project requirements, desired scale and 100500 other factors.

Networking is an advanced topic and even major developer studios don't get it right.

My point is: if you're a beginner, don't even think about networking. Do the learning, develop a single player title. Once you're at least intermediate+ overall, you can maybe start a networking project.

[icy junco]

allright thanks a lot

[languid spire]

Networking is the ultimate Catch-22 situation, you can only do it well if you already know how to do it well

is there anyone that could help me with my problem when i press E or mouse0 on the weapon i want to pick up it just goes invisble when its picked up and it still shoots and stuff

[pliant marsh]

is there any way to change the tag of clones of an object. This script is for spawning circles in random coordinates to the right of the screen so that the main player(the square) has to dodge them. The scripts creates clones of the circle just fine but for some reason the clones dont keep the istrigger is true from the original circle. The clones also dont keep the tag of the original circle either. I was able to fix the is trigger part by just always setting it to true but I'm not sure how to fix the tag problem. I tried just typing Gameobject.tag = Rock(the tag i want it to have) right after line 25 but it came up with an error.

this is the error that occured

[teal viper]

Occured where?

Why would you delete the part that you're asking about..?

[languid spire]

so you didn't use a.tag = ?

[pliant marsh]

delete what?

[pliant marsh]

oh

i put it back in the script

[pliant marsh]

this error came up again

[languid spire]

does that look like a.tag ?

[pliant marsh]

i created a tag called Rock

but only the original circle has it

the clones dont

[languid spire]

GameObject is the class, not the instance of the class you are trying to change

so my debug.log of the move goes to -1 the first time I move left, but when I turn right, it stays at positive 1 even if I have the left analog stick going left. Im trying to add a dash function and thought it'd be easier if I just add a force in the direction of the analog stick, but not sure how id be able to get it to dash left if the move.x never goes negative aside from the first time

Hello guys, i follow the Little Adventurer: Learn to make a 3D action game with Unity tutorial of Single-Minded Ryan in udemy, to make a 3d action game and i have an issue about raycast hit for damage system.
I added a box collider to another object on child of my character and set the box collider, i just wanna create raycasthit but raycast hit is stuck some point and doesn’t work like i wanted.
It doesn’t go through z-axis of box collider, why it happened? Here’s my gizmos method:
private void OnDrawGizmos()
{
damageCasterCollider = GetComponent<Collider>();
if(damageCasterCollider == null)
{
Debug.Log("a");

}
RaycastHit hit;

Vector3 originalPos = transform.position + (-damageCasterCollider.bounds.extents.z) * transform.forward;

//Debug.Log("Transform Position: " + transform.position);
//Debug.Log("I dont know wtf is it: " + (-damageCasterCollider.bounds.extents.z));
//Debug.Log("Standart transform forward value: " + transform.forward);
//Debug.Log("Original position: " + originalPos);

//Debug.Log("I dont know wtf is it: " + (damageCasterCollider.bounds.extents));
bool isHit = Physics.BoxCast(originalPos, damageCasterCollider.bounds.extents / 2, transform.forward , out hit, transform.rotation, damageCasterCollider.bounds.extents.z, 6);;
Debug.DrawLine(originalPos, hit.point);
Gizmos.color = Color.yellow;
Gizmos.DrawSphere(hit.point, 0.3f);

if (isHit)
{
    
    Gizmos.color = Color.yellow;
    Gizmos.DrawSphere(hit.point, 0.3f);
}

}

does anyone know an asset for sound occlusion?

[slender cargo]

Right so I have a array for some cards, I would like 5 cards to display on the screen at a time. Currently the player can scroll through the displayed cards. But I want it so when it gets to the end of the displayed cards, It removes the first displayed card and then adds a new displayed card from the array.... But I'm not sure how I'd code that?

so lets say I have 15 cards, I only want 5 to display at a time. Just need to be able to cycle through the array

and when I get to the end of the array, It starts from the beginning again

I can do it with 1 card easily

but not sure how to do it with 5 cards and then adding cards which are not currently in the scene

[gaunt ice]

you need a sliding window
btw you will never show (magnify) the last card

[slender cargo]

For example 1,2,3 is displayed

[slender cargo]

Sliding window, How is that used?

[gaunt ice]

or cicular buffer (queue)
you cant use c# built-in one since its doesnt support random access
eg if you have an array and you want to show 4 cards at once
1 2 3 4 5 6 7 8
h t
then you show the card from h to t, each time to you turn left: h-- and t--, turn right: h++ and t++ and mod the queue capacity

[slender cargo]

I could add the cards onto the Scroll view UI element and scroll to only show the cards in which I want displayed?

[gaunt ice]

https://www.geeksforgeeks.org/introduction-to-circular-queue/

[slender cargo]

hm yeah, that is something I'll probably look into

[buoyant rune]

how do u change that camera size to a different resolution size

[queen adder]

All right guys I have big issue in my mind. So let's imagine it, I have created two scripts; first one calls "Gun" and other one is "GunController". And I didn't write anything into "Gun" script. As you can see I writed these codes that i sended in picture. But I have question in my mind. As you can see there is parameter calls "startingGun", also I have prefab weapon. I didn't understand how can I assign this weapon prefab as "Gun" type parameter. prefab is gameobject but "Gun" is just script.

[low path]

Are you saying that you dragged your prefab object to the StartingGun in the inspector and are confused how you can assign a prefab to a variable that isn’t “gameObject” type?

[queen adder]

Yes exactly

[low path]

If so, the answer is just that Unity is smart enough to find the correct component on the prefab you drag in in the inspector.

If your prefab has a component of the variable type you are assigning, Unity will just assign your prefab’s component to that variable.

[queen adder]

I didn't put anything on this prefab. Literally nothing

[low path]

Do you have a gun script on the prefab at all?

[queen adder]

and I'm suprised that i didn't get any error. Also as you can see, when I created the new gun i signed as Gun

[low path]

Even an empty one?

[queen adder]

Literally nothing

none

[low path]

Can you show the inspector for your gun prefab?

[queen adder]

I'm not able to reach the inspector bcs im on another pc

so basically "Gun" script type can store prefabs?

[keen dew]

Come back when you have the project open and you can check what you actually have

[quaint thicket]

I can't get my keyboard WSAD movement to work. It doesn't detect when the buttons are pressed. Any ideas?

    private void OnEnable()
    {
        movementInput.Enable();
    }

    private void OnDisable()
    {
        movementInput.Disable();
    }

    private void Awake()
    {
        GO = GameObject.Find("Model");
        characterController = GO.GetComponent<CharacterController>();

        // Initialize the movement input action
        movementInput = new InputAction("Movement", InputActionType.Value, "<Keyboard>/wsad");
        movementInput.Enable();

        // Register the movement callback
        movementInput.performed += ctx => movementDirection = ctx.ReadValue<Vector2>();
        movementInput.canceled += ctx => movementDirection = Vector2.zero;
    }

    private void Update()
    {
        // Move the player based on input
        Vector3 movement = new Vector3(movementDirection.x, 0f, movementDirection.y) * movementSpeed * Time.deltaTime;
        characterController.Move(movement);
        Debug.Log("Update - movement: " + movement);
    }
}

[queen adder]

Okay my bad, my prefab had "Gun" script. So basically when the prefab has the script, so this script parameter can store this GameObject?

[cosmic dagger]

what do you mean by script parameter?

[queen adder]

I mean this parameter calls "startingGun" which is the parameter of "Gun" script right? or is this my fault to describe it.

[low path]

If you have a variable in a script that has a gameobject OR component type, then Unity will let you drag a prefab with that component on it to the component type.

Then that component variable effectively has a reference to your prefab although what it really has is a reference to the specified component on your prefab.

[queen adder]

All right, thank you so much

[cosmic dagger]

a prefab is a GameObject stored as an asset in project folder. if that GameObject has a Gun script attached to it, then you can assign it to a variable with a Gun type . . .

a script attached to a GameObject is a Component. a Component is a Type. if the GameObject has a component matching the variable type of a script, you can drag it as a reference into that variable slot . . .

[queen adder]

thank you for everything and I'm sorry if i bothered with my question but I'm new at this. So it's hard for me the understand the all concept

[cosmic dagger]

not a problem, good luck!

Hi guys how would i get an object to spawn in front of another object when its enabled? in my case i have coins spawning every so offten randomly. and i want a cloud to cover them when they are enabled? my game is 2D

[thorn holly]

I’m a little confused about what you’re trying to do. Should there be one cloud per coin?

[dark prism]

yes

like one cloud for each coin that is spawned

[swift crag]

so you want to have a little "poof" as the coin spawns in

and then the poof goes away

[dark prism]

the reason in doing this is beacasue i have object pooling in my game. and if i was to spawn the cloud/ make it a child to the coin. it will get destroyed and not come back when enabled again if that makes sense

[swift crag]

Okay, so you'll want to spawn a cloud prefab in the coin's OnEnable method (or fetch one from another object pool)

[dark prism]

ill show you a clip of the game. so it make more sense. im just popping out now so ill send it in a second

[summer wasp]

how can i activate a particle system from a prefab with the script in another?

    if (fogo != null)
    {
        Debug.Log("Particle System Found");
        fogo.Play();
    }

the debug log is appearing, but the particle is not playing

[wintry quarry]

why are you trying to play a particle system on a prefab?

prefabs don't exist in the scene

[hot wave]

I fixed the clamp

but transform.rotation = Quaternion.Slerp(transform.rotation, targetRotation, Time.deltaTime * 5.0f); is it ok to multiply time.deltatime to 5?

or no

I wanted to make it faster, but I might be making x5 more calls?'

[wintry quarry]

the numbers you plug into the parameters have nothing to do with how many times this code is running

[hot wave]

Time.deltaTime * 5.0f so this is just how fast it moves or reacts? or no

[wintry quarry]

You're not really using Slerp correctly in any case

so it's kind of esoteric

[hot wave]

what is esoteric

[wintry quarry]

mysterious

not clearly defined

The third parameter in Slerp is supposed to be the percentage from A to B you want the result to be

but you're misusing Slerp (in a very common way) in a way that makes the units or meaning of that parameter very hard to define

[hot wave]

        {
            RaycastHit hit;
            Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);

            //See where a ray from mouse position hits our invisible lever plane, and have lever look at that point
            if (Physics.Raycast(ray, out hit, 10, leverPlaneMask))
            {
                Vector3 lookPosition = hit.point - transform.position;
                lookPosition.z = 0; //We can zero out one of the axis because the lever cannot move in all 3 axis
                //lookPosition.x = Mathf.Clamp(lookPosition, -90f, 90f);
                Quaternion lookRotation = Quaternion.LookRotation(lookPosition);
                if (Quaternion.Angle (lookRotation, baseRotation) <= maxAngle)
                {
                    targetRotation = lookRotation;
                }

                //transform.rotation = lookRotation;
                transform.rotation = Quaternion.Slerp(transform.rotation, targetRotation, Time.deltaTime * 5.0f);
                Debug.Log(hit.point);
                //transform.rotation = Quaternion.Lerp(transform.rotation, targetRotation, Time.deltaTime * 5f);
            }
        }``` it is like this, but not sure if I did it right

but it works i think

also, i dont really know how to use it much since I am just starting, everything will be wrong, but I want to learn

[wintry quarry]

It will work it's just not easy to adjust or think about the speed in any sense

like it's not "meters per second", it's not going to swing the lever all the way in some defined number of seconds.

There's no concrete measurements to reason about - you just kind of adjust those numbers and see if it "feels" right

and it's also going to slightly have different behavior based on framerate. But it will generally feel "ok"

If you used for example Quaternion.RotateTowards(current, target, Time.deltaTime * 5f); then you could confidently say "the lever will rotate at 5 degrees per second"

Also Slerp used in this way will theoretically never completely reach the end state

[hot wave]

I also checked, it doesnt fully go to the end

so first one is current and 2nd is target?

[wintry quarry]

for RotateTowards it's (current, target, speed)

for Slerp/Lerp it's supposed to be (start, end, percent)

but you're doing (current, end, some arbitrary number)

which gives a nice effect and is used commonly, it's just a little bit odd to work with

[hot wave]

ah I see I see , I never knew about RotateTowards

I think it is what I need

thank you praetor

[elder osprey]

What is the point of multiplying by Time.fixedDeltaTime instead of 0.02?

[wintry quarry]

Fixed timestep can be changed (in code or in the editor)

Is your cloud prefab at 0,0,0?

[elder osprey]

Oh, that makes sense. In my case why do I need to multiply acceleration by Time.fixedDeltaTime. Here is what I mean:

Velocity.x = Mathf.Lerp(velocity.x, inputVelocity.x, acceleration * Time.fixedDeltaTime)```

[wintry quarry]

Well you're misusing Lerp here, but in general the third parameter to Lerp needs to be between 0 and 1 or it's pretty meaningless

[polar acorn]

Because you're using Lerp wrong
https://unity.huh.how/lerp/wrong-lerp

[tall delta]

in this case it's a bit wired because of the whole lerping business. but the short answer is that when dealing with physics based movement, most of the time you need to use the time component in one of the kinematic formulas. and using a constant time derivative like FixedDeltaTime makes it infinitely easier to deal with getting the calculations 'correct'

[wintry quarry]

Sure but I want to point out in this case that's completely irrelevant and this used of fixedDeltaTime is merely a constant mul;tiplier into an awkward misuse of Lerp

[tall delta]

I totally agree, hence the preface of my message. but thought it might be helpful to know / understand why people and tutorials will keep telling you to use FixedDeltaTime when dealing with physics movement 😄

[summer stump]

Also to be clear, when I hear "physics movement", I think AddForce and setting velocity (and not MovePosition or setting transform.position, which are not physics).
For physics based movement you do NOT want to include a time component like FixedDeltaTime because that is already included behind the scenes, or in the case of ForceMode.Impulse, it is unnecessary

It IS needed in NON-physics-based movement though

[tall delta]

fair enough, but I think you're arguing semantics at that point, because when I hear non-physics based movement. I think of stuff that doesn't use the kinematic formulas at all, and are just about feeling good. often not even using fixed update

[rocky canyon]

nah its not symantics.. if ur setting velocity directly in fixed update theres no need for scaling

[summer stump]

I don't think this is semantics. Physics based has a specific and defined meaning. The way I described it is what it means..
Physics based means it moves via the physics engine and reacts to physics forces.

[rocky canyon]

ur just compressing the multiplier

leading to higher values to achieve the samething

if ur doing ur calculations in update then yea it might be necessary

    private void ApplyGravity()
    {
        Vector3 gravityForce = new Vector3(0f, -gravity, 0f) * rb.mass;
        Vector3 gravityAcceleration = gravityForce;
        rb.velocity += gravityAcceleration * Time.fixedDeltaTime; // this is when i'd use fixedDeltaTime
    }```

[silk night]

iirc velocity does not need timescaling

only if you change position directly

[rocky canyon]

anytime i do += or *= i include either Time.fixedDeltaTime or time.deltaTime depenind on where it is

[silk night]

cause position change is velocity * time

[rocky canyon]

ya i think ur right tbh

b/c velocity only gets calculated during the fixed time step

if u were calculating the velocity in update.. w/o scaling that.. now that would be an issue i would assume

[silk night]

no velocity in general

[rocky canyon]

like custom calculations

[silk night]

no time scaling

[summer stump]

Velocity is in meters/second, so it is already scaled by time

Maybe I should have said physics ENGINE based earlier, and that would be clearer. Now that I think about it

[rocky canyon]

depends on where ur calculating that velocity

[summer stump]

Velocity and AddForce are handled by the physics engine directly

[rocky canyon]

physics are always fun 😄

im guilty of modifying the velocity.. i rarely use AddForce

never noticed an issue tho.. the engine pretty robust

[summer stump]

It's a perfectly fair way to do things 🤷‍♂️

[foggy crypt]

Is there a way to change scene index?

[rocky canyon]

im not math savy enough to use AddForce

[silk night]

AddForce is basically just a utility function for changing the velocity 😄

[summer stump]

Yeah. In the build settings

[tall delta]

multiplying by fixedDeltaTime is correct in that example, when manipulating rb.velocity. what's not correct is multiplying by rb.mass. since in this context we're getting the acceleration of gravity, not the force.

[rocky canyon]

ya, but when u use AddForce.. and u want things proper its difficult for someone thats not math savy.. using equations to get the right speed/vel

or atleast for me it is

[silk night]

No, you should never multiply velocity by timescale in unity, neither fixed nor normal timescale

Unity already multiplies the velocity value by timescale, by multiplying it with timescale again you cause timescale to have an exponential effect on the distance your object travels

[rocky canyon]

i know its simple.. but sometimes i get hung up on it

[foggy crypt]

Thank 🙂

[summer stump]

You have to just reorder the scenes btw

[rocky canyon]

drag and drop

[tight fiber]

Hi, I'm new to Unity and I would like to know what you would recommend to me to progress quickly (tutorial, project, etc.) for my final project, a multiplayer card game.

[rocky canyon]

say i want something to move X meters per second

        float requiredForce = rb.mass * targetSpeed / Time.fixedDeltaTime;
        rb.AddForce(transform.forward * requiredForce, ForceMode.Force);```
wouldn't this be the right way to do that?

[summer stump]

Cut your project into tasks and solve these tasks one by one in a playground, in the end the last task is bringing it all together

[rocky canyon]

start simple.. do something, build on that something.. rinse and repeat

[wintry quarry]

Vector3 velocityDiff = desiredVelocity - rb.velocity;
rb.AddForce(velocityDiff, ForceMode.VelocityChange);```

of course you can also just do rb.velocity = desiredVelocity;

[rocky canyon]

i wish i'd payed more attention in school

[tight fiber]

thx

[rocky canyon]

so theres no need to use the mass?

[silk night]

if you want a fixed speed no

if you want to calculate how hard an object bouncing into yours affects the speed then yes

[wintry quarry]

VelocityChange accounts for that

[rocky canyon]

okay cool.. i need to start doing stuff like this.. w/ math in mind.. soo far in physics i just tinker and change values until i get wat i want..

thats not the proper way to really learn anything

[tall delta]

rb.velocity = transform.forward * targetSpeed; would also do the trick

[rocky canyon]

what math subject do physics calulations fall under? in school i took Physics 1 and 2 but isn't it included in some other branch of math?

calculus maybe?

[silk night]

isnt that algebra? not sure tbh

[rocky canyon]

yea, u may be right.

all i remember in physics we had these "train problems" and it would take a whole 2 pages of college ruled worth of work..

(you had to show u work or u'd flunk)

[wintry quarry]

vector arithmetic?

[rocky canyon]

a train leaves station a, heading towards station b at 10:00 travelling..

that type of junk ☝️ lol

[wintry quarry]

that would be algebra but depending on the nature of the equation that results you might need calculus to solve it

[rocky canyon]

alrighty.. sounds legit. i need a refresher on that stuff for sure imma go hunt down some tutor type sites and see how rusty i am

[tall delta]

it depends, you need calculus (specifically understand, integrals, and derivatives). for calculations that involve change over time (like if acc isn't constant). but for most use cases just learning the kinematic equations for constant acceleration is more than enough. and that's just simple algebra

[rocky canyon]

these would make EPIC examples to recreate in unity

all the exam questions i can remember all involved cars, trains, planes, rockets, and balls

not sure where to find a sk at..

[cinder crag]

im having a bit of a problem , i dont really know how i can make a smooth dash ability like daves dash tutorial since im using a character controller and he uses a rigidbody , how can i make it like his but character controller?

https://youtu.be/QRYGrCWumFw?si=xWCav_H03XuECfVw

[rocky canyon]

just like ur doing there.. all u need to do is flip that canDash bool to true... and set it back to false in the coroutine

[worthy merlin]

Was watching a video that was telling people to use [SerializeField] instead of public to declare variables. Is there a reason behind this preference?

[rocky canyon]

yes, w/ serializedfield u can keep the variable private

private is better than public..

less chance to f*ck up ur code

[modest dust]

Mostly because you don't want public fields all over the place

In most cases you need close to none public fields

[rocky canyon]

only use public variables when u need access to them outside the class theyre within

[worthy merlin]

ah

[cinder crag]

It looks pretty bad ngl , I watched Dave's dash tutorial and I want it like that but I'm using a character controller and he uses rigid body so idek how to do it with a character controller

[worthy merlin]

Understood, will be following this henseforth then

[rocky canyon]

1 sec i have a dash mechanic on one of my CC projects, let me find it and i'll show u some example code

[rocky canyon]

serialized field FTW

ignore the [ReadOnly] thats something else

[cinder crag]

Ooo , thank you! Appreciate it

[rocky canyon]

its a hefty boi

[tall delta]

sound to me like you just want the movement to be a bit smoother, I think an animation curve is the easies thing to use here.

    public float dashDuration = 5.0f;
    public float dashSpeed = 10.0f;
    public AnimationCurve accelerationCurve = new AnimationCurve(new Keyframe(0, 0), new Keyframe(1, 1));

    IEnumerator Dash()
    {
        float elapsedTime = 0.0f;

        while (elapsedTime < dashDuration)
        {
            float normalizedTime = elapsedTime / dashDuration;
            float speedMultiplier = accelerationCurve.Evaluate(normalizedTime);
            transform.Translate(Vector3.forward * dashSpeed * speedMultiplier * Time.deltaTime, Space.World);
            elapsedTime += Time.deltaTime;
            yield return null;
        }
    }

then you change the accelerationCurve in the editor to match the 'smoothness' you want

[elder osprey]

Thank you, I will fix this when I get the chance.

[elder osprey]

Oh! That makes sense, thank you.

[rocky canyon]

https://www.spawncampgames.com/paste/?serve=code_816

this is how i did it.. (for input I just set isDashing to true) then the coroutine sets it back to false..

the dash vector is just added into the Move function.. and at the end of it im slowly lerping it back to zero..

so when i hit the button it adds the dash value i have assigned.. and then it takes care of itself..

[cinder crag]

Oh boy , what project were you making for this?

[cinder crag]

I will try yours and spawns code and see which one fits my game , thank you!

[rocky canyon]

a pirate game i abandoned @cinder crag

you can see the dash towards the end (its a little subtle) but i didnt want it to be a big dash

[cinder crag]

Let's gooo RGB pirate ship

[cinder crag]

Looks cool

[rocky canyon]

yessir lmao

thx

[cinder crag]

Npnp

[rocky canyon]

i might return to it sometime

[cinder crag]

Would be cool if you finish it ,

[rocky canyon]

i bit off more than i can chew

[tall delta]

that actually looks pretty sick 😄

[rocky canyon]

scoped too big

[rocky canyon]

if i had a team i'd probably try to finish it

[rocky canyon]

lol BOOM

oh i forgot dash += Camera.main.transform.forward * (playerSettings.dashForce * 1f); i do this when i get the input for dash... then the move function calls the coroutine because the dash force is now greater than the magnitude i assigned cs if (dash.magnitude > dashMagnitude) { finalVelocity += dash; StartCoroutine(Dash()); }

i wrote it a long time ago.. sooo its not the best code tbh
but it works..

[cinder crag]

lol

[golden ermine]

Hi I have this code that I assign to gameobject which I then put on my two buttons, one is SAVE and one is LOAD. When I click SAVE it will save my data(player and cam position and amount of deaths) and when I click LOAD it will load all that data. Problem is that I have SAVE and LOAD button in my game scene and I want SAVE button in my game scene and LOAD button in my main menu scene but then I dont know how can I implement same method to just load game data and load game scene.

[cinder crag]

check dms when u can

[wintry quarry]

make the save manager a DDOL singleton

[golden ermine]

like this

but also my SaveServiceSystem script is on gameobject inside game scene and menumanager is in main menu scene

[wintry quarry]

that's just a static instance property

Which is only one part of making a DDOL singleton

[wintry quarry]

you would need it to exist either in both scenes or dynamically load it in on demand

and enforce its singletonness

[golden ermine]

which method is easier

[rancid tinsel]

is there a quick way to make this change the instance of the script rather than the script itself?

[polar acorn]

Yes, like that

[rancid tinsel]

but it is changing the script for all instances

[wintry quarry]

unless you made your variables static it won't

[polar acorn]

This code will be changing the values of the BallistaScript on the selectedTower object

[golden ermine]

and why do I need to make DDOL singleton cause that script is in scene that will be loaded after being in menu

[rancid tinsel]

oh nvm

i thought it was changing it for all of them but it isnt changing it for any lol

mb

turns out im an idiot and forgot to actually use the function anywhere

[wintry quarry]

If you want to load data in one scene and have it accessible in another you're going to need to have a way to move data between scenes. A DDOL singleton is one good way of doing that.

[golden ermine]

like this?

[wintry quarry]

no

that doesn't enforce it being a singleton, nor does it assign the instance property anywhere.

just look up Unity DDOL singleton for examples

[rancid tinsel]

if im not crazy, at 2 base attack speed this should give 0.4 attack speed at first and then 0.8 attack speed after right? making it 3.2?

[gilded verge]

ok so im trying to make an fps i managed to make a camera that renders the world and another that renders the weapons. how do i render the weapon cam on top of the world cam?

[wintry quarry]

something like that yes

[golden ermine]

Will that work like that or should I add something more so it becomes ddol singleton

[wintry quarry]

depends on your render pipeline but you want either camera stacking or camera composition / overlay and base cameras

[gilded verge]

im using URP

[polar acorn]

Try logging the values before you do the math, they probably aren't what you think they are

[rancid tinsel]

i think i just figured it out

[golden ermine]

And I still dont understand how will I get that data saved from my game scene and when I again start to play game and im in main menu, then I click load game how will it load my data that was saved when I clicked on save button

[rancid tinsel]

i was increasing the upgradeCount before calling the function

[foggy crypt]

Hello
object.DontDestroyOnLoad for some reason creates a copy of an object it is refered to everytime a different scene loads:

void Update()
{
    Object.DontDestroyOnLoad(this);
}

[wintry quarry]

you need to simply load it into a POCO and read it from the save manager when needed

[golden ermine]

what is POCO?

[wintry quarry]

i.e:

• Press load in main menu to call the load function
• Load simply loads the data into a plain object and stores it on the save amanger
• You load the game scene
• Game scene script reads the loaded data from the save manager

plain old C# object

[wintry quarry]

Why are you doing it in Update you monster

[foggy crypt]

But it doesnt work in Start too 😦

[wintry quarry]

anyway it doesn't make a copy it simply moves it into the DDOL scene
