there are cases where magic strings can't be easily avoided, usually when interacting with external systems like shaders. but unity object references is not one of those cases

there is a built-in method to get objects by name, Find, but for the reasons mentioned above, you generally shouldn't use it, and in 99.999% of cases you won't need to anyways.

[scarlet pasture]

okay, so u all never build a fallback in awake?. i also never really saw that in a tutorial, i dont really know why and from where i got this hahah

but okay, atp i use SerializeField

Thanks for the Explanation.

[sour fulcrum]

As mentioned previously fallbacks in general aren’t really a thing no

Only when valid results are out of your control i suppose (eg. Network related)

[keen dew]

Fallbacks are used for things that have a reasonable chance of failing, for example network requests or connecting to a gamepad or something like that. But things like assigning component references either always work or never work, so there's no point in making a secondary mechanism for it

[umbral bough]

bump

[naive pawn]

yep, so i get fail-fast behaviour.

[teal viper]

You might need to cache the input in an update loop. It's not clear where OnScenrGUI is called and whether inputs are valid at that point of frame.

[scarlet pasture]

what is fail-fast behavior?

[teal viper]

I noticed fallbacks are something that AI likes very much when refactoring code. So perhaps that's where you got it from? 😏

[umbral bough]

https://github.com/nnra6864/SmoothSceneCamera/blob/master/Editor/SmoothSceneCamera.cs#L120

[scarlet pasture]

yeah, in my first weeks i use ai alot for Synatx etc

[naive pawn]

"if something goes wrong, stop and give me an error message that tells me what went wrong"

[umbral bough]

you said it's not clear where it's called, so I sent the line it's called from

[naive pawn]

Used in EventType.MouseDown and EventType.MouseUp events.
from Event.button

so yeah that just.. doesn't work

[teal viper]

What I meant is, that it's not clear where unity calls it. Unless that callback is invoked in your code..

[umbral bough]

yeah, I was just trying random stuff from recommendations, which didn't work, so I am asking for help now

[naive pawn]

scrolling and clicking are just, separate events

you don't get the full status of the mouse as part of the event

you need to store that separately

[naive pawn]

(this is how UI events work in general, not just unity)

[umbral bough]

I see, so you would suggest running the update loop and checking whether certain buttons are pressed?
If yes, should I use the old input manager or what?
Iirc that's deprecated, but idk what else to do since this is a really small asset you are supposed to just import into the project and it works.

[naive pawn]

not sure where you got that suggestion from

[umbral bough]

here

[naive pawn]

im not the same person as dlich

[zinc totem]

I have a question, How do you implement jump mechanics in 2D top-down?

[umbral bough]

well yes, but it happened during the same conversation and that's all the info I have, I am fully open to other suggestions

[naive pawn]

that's kinda a design question rather than a code question, no?

you could not have them, you could have gaps, you could have a 3d dimension, you could utilize faking height with a Y offset, or multiple of the above

[naive pawn]

you need to store that separately
you just need to keep a state between events

the scroll and the hold will not come at the same time

(not sure why you did button == 0 anyways though.. that's left click)

[naive pawn]

really small asset you are supposed to just import into the project and it works.
well i mean, you modified it to make it not work lmao

[teal viper]

Considering it's in editor, there's likely an event you can hook to on input or at least some callback where it's routing the input data.

[umbral bough]

Are you sure about that?
I went with 0 after debug logging.

[naive pawn]

yes, the standard is 0 = left click, 1 = right click, 2 = middle click

[umbral bough]

I see.
Could you point me to some resources or something?
I am genuinely not sure where I'd even start with that tbh.

[teal viper]

Ah, I guess it could just be a logic error then.

I'd confirm what Chris is saying first.

And if not, then documentation is the place to start.

[umbral bough]

well that's accurate, except for the left click

it just stays at 0 when I lmb

[naive pawn]

nope

as the documentation says, it's used for mouseup/mousedown events, not scrollwheel
it was probably just 0-initialized

[naive pawn]

so what's inaccurate about it then lmao

[teal viper]

Actually, looking again at the code, I stand by what I said.

[umbral bough]

Wait, my bad, I think I see what's happening.
There's probably another bool or sm to check whether we got any mouse input this frame.
If yes, then we'd check the code.

[naive pawn]

there probably isn't

again - they are separate events

[teal viper]

The issue is that they're not in any input callback, but in on scene gui. So whatever happens to be the current event at that time is returned.

[umbral bough]

I see.
I chose to go with on scene gui since this bind should only work in the scene view.
Was that a bad choice?

[teal viper]

What's Event? I thought it was unity api, but I don't see it in the docs...

[naive pawn]

you just need to store the state separately, like i said initiallyjs OnSceneGUI() { var e = Event.current; if (e.type == EventType.ScrollWheel && e.modifiers == EventModifiers.None) { if (rightClickHeld) { ChangeSpeed(e.delta.y); } else { Zoom(e.delta.y); } e.Use(); } } it would have to be something like this, and then keep the rightClickHeld state according to events you receive of type MouseDown and MouseUp (potentially also in this callback)
(also probably with better names, like whatever rightclicking is supposed to do)

can't confirm this would actually work, due to the event processing stuff dlich mentioned, though.

[naive pawn]

hm, i googled "event unity" and got this as the first result
https://docs.unity3d.com/6000.2/Documentation/ScriptReference/Event.html

[umbral bough]

I'll be fully honest, I don't know.
That part of the code was suggested by ai as I just wanted to get it to work as fast as possible at the time and didn't bother reading docs.
That's how we ended up here ig.

[naive pawn]

oh my god this bullshit again

at least read the damn docs of whatever you're using

[teal viper]

Yeah, for some reason I got unityevent results first and assumed that's the only thing.

[umbral bough]

ok, well thanks for the help

[teal viper]

So yeah, Chris is right.

Read the docs page.

And then your code again.

Note how the docs mention a different callback too.

Not the on scene gui

[umbral bough]

This was quite useful, thanks, this is how I solved it:

var e = Event.current;
if (e.type is EventType.MouseDown or EventType.MouseUp)
{
    var isDown = e.type == EventType.MouseDown;
    if (e.button == 1) _rmbPressed = isDown;
    else if (e.button == 2) _mmbPressed = isDown;
}

Hi, I'm currently a uni student, recently got into unity and our assigment is to create a game. I need help explaining the coding logic behind AI detection + chase + patrol, we're making a stealth game with zombies, but it seems it's going to be overly complicated with the AI for people who just began using unity

We got around 9 weeks and it would be amazing if someone taught me some basics

What would be the a good way to sync animations and AI if an enemy being a MonoBehaviour FSM in Update?
Last time I used to make use of StateMachineBehaviour scripts on states toggling different variables in the animator
but that's just disgusting and I have to make a new var/script for each state

main issue is figuring out a moment when the animation ended

[teal viper]

animation events

[real thunder]

public class StateMobAttack : StateMachineBehaviour
{
    override public void OnStateEnter(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
    {
        animator.SetBool("IsAttackingEnded", false);
    }
    override public void OnStateExit(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
    {
        animator.SetBool("IsAttackingEnded", true);
    }
}

this script of mine makes me very sad

[empty onyx]

It depends on what you want to achieve. Apart from the method you've just mentioned, you can call specific events from animations at a specific frame, so you can execute logic very precisely

[regal aspen]

hello is there anyone i can ask for help with some code? i'm doing a 2D space shooter for a course and i've run into some walls i can't really wrap my head around. i asked the instructor for some advice and he gave me a non-answer. i understand he can't just give the answer but i'm stupid (to put it bluntly) and need the direction

[real thunder]

I can pinpoint my exact issue where a mob is in an "attacking" state and a player is far away
I want it to stop attacking and go chasing the moment animation of an attack finished
And so far it's the best callback I figured I can get

mecanim just makes me sad, tell me if you know better solution to the problem I mentioned

there are events but they have edgecases with blending and don't look good for game logic

[regal aspen]

sorry. i'm trying to set up a laser weapon using the Raycast function and to have it bounce off of a wall using the standard collision we were shown "if (collision = ect)" but when i use the input for the object's layer "gameObject.layer = 6" it gets upset and spits out an error

[scarlet pasture]

so u want to know the Animation Ended?

[real thunder]

yes

[rocky canyon]

https://www.youtube.com/watch?v=85kogmzcLXw
big info dump of ai informations

[scarlet pasture]

im really not the best, u can use either a Animation Event via code that say "Im Done" or u only use Code like i thid

i can send u a exapmple code

the Script automaticly detects if the Animation is done

[fickle plume]

Make sure you are not confusing assignment = with comparison ==

Other than that you should post the code with the question.

I mean my does that and it's short but it's just icky that I can't figure out something more clean

our project is too ambitious for the time we got haha

why is u not clean waht u mean with that?

it feels like a crutch that's what I mean

also, there is this thing with Input Action manager and another way to do movement without it, which is better for a beginner?

what is going on here if(collision = (gameObject.layer == 6))

[scarlet pasture]

@BlackHunter my englisch is chopped u need to explain the a little more so i understand u correlty

[real thunder]

I just use basic input and remove Input System package because I do small games so fare and they don't need remapping/whatever

[regal aspen]

wtf

[rich adder]

backticks

[scarlet pasture]

no this is the wrong sysmbol

[rich adder]

literally copy them from the bot message

[naive pawn]

backticks are to the left of the 1 key on most keyboards, same key as tilde
if you can't find it, just copy from the bot message

[regal aspen]

will do

omg i just found it give me a moment

public class Laser : MonoBehaviour
{
    [SerializeField] private LaserData LaserConfig;


    private void FireLaser()
    {
        Physics2D.Raycast(Vector2(PlayerShip.transform.position, PlayerShip.transform.position), Vector2(10, 0));
    }

    private void OnCollisionEnter2D(Collision2D collision)
    {
        if(collision = (gameObject.layer == 6))
        {

        }
    }
}

i'm not smart i'm so sorry

[real thunder]

it's other way around, I realized that English speakers don't use the word crutch as a label for dirty hacky solutions

[naive pawn]

so yeah, what's going on there ^

[regal aspen]

trying to get it to recognize walls which have a specific layer

[naive pawn]

you're assigning a Collision2D to a bool?

[naive pawn]

if you want to check if it should collide, you don't need that collision = at all. just use the == in the conditional

[regal aspen]

neither of those work it gets mad with both

[naive pawn]

or better yet, set layer collisions properly so they don't collide if you don't want them to collide

[naive pawn]

yeah because that's not actually the issue here

[polar acorn]

Well, yess, because collision is not a boolean

[naive pawn]

collision = doesn't make sense at all

[polar acorn]

gameObject.layer == 6 is a yes or no question.
What you're asking is, "That object I collided with, is it a 'yes'?" which doesn't make sense

an object is not a yes

[naive pawn]

also you can just do this to avoid the magic number as well

[scarlet pasture]

im not a englisch Speaker, im from germany. im honest with u i dont really understand what the problem is, sorry my englisch skills are to bad

[hexed terrace]

there's no c in English!

[regal aspen]

ok... so how would i do this properly because my instructor won't help me aside from throwing me a new shovel to dig myself deeper

[real thunder]

my problem is "what I did is ugly, is there really no better solution!?"

[scarlet pasture]

what is ugly? u mean u code?

[real thunder]

general solution

[polar acorn]

== means "Are these things equal". It gives you back a sheet of paper that says either "YES" or "NO"

collision is a collision event with an object. It's basically a big book of math formulas that says "Okay, you hit this object going this fast at this angle and so on".

You are asking if the contents of that book are the word "YES". Which it is not. They are not the same thing.

@regal aspen Further explanation as to the problem

[polar acorn]

Wrong reply

sorry

[scarlet pasture]

np really not that depp

[scarlet pasture]

u used Animation Event?

right to detect is the Animation done?

[real thunder]

I used OnStateExit because it's more stable

[scarlet pasture]

dayumn i didnt know that this even exist, im new i thought u also are a begginer, i can send u how i did that and u can see if u maybe like that also, sorry i didnt really understand u corretly befor

[real thunder]

but it looks bad, and using animation event would look bad, honestly, I am thinking if I should just use a timer

[scarlet pasture]

yeah i also dont like Animation Events

[hexed terrace]

why do you not like anim events ?

Events are generally better than timers (depending on the situation) ...

In this instance.. you change the length of the animation and you either have to remember to update your timer var, or have something to update it for you.

An event will just fire when it's finished regardless, no thought beyond that required from you.

[naive pawn]

they didn't say that tho

[real thunder]

you mean why I don't like them?
because they run on blending transitions unpredictably and I suspect they might be missed if something lags really hard

[hexed terrace]

yes, obvious missed word/ typo

[real thunder]

every section I read about animation events screams that I should not use them for crucial logic

[scarlet pasture]

i also only use them for Logic

[scarlet pasture]

[naive pawn]

just ask, don't ping random people. doesn't make me any more likely to help

https://dontasktoask.com

[scarlet pasture]

Sorry

[real thunder]

so I only use them for sounds and visuals and to determine moments when to execute meleehit/shoot code

as for determining the moment when a mob must go from attacking to moving, nah

OnStateExit gives me that info nicely but the idea of using a script just for that looks silly

but I am getting an impression it's either that or timer

[scarlet pasture]

from Attacking to Movement u also can just use a "Has Exit Time" => 1

[hexed terrace]

Dont care about look of code in that respect.. care about functionality and move on

[scarlet pasture]

so the Enemy plays the Attack Animation and after it end exactly of the Attack Animation it goes to Movement if this u only 2 Animation it would work fine i think

im also not the best must i say but i think this would work

fine

[real thunder]

I was doing that and I was ending up under piles of spaghetties

[hexed terrace]

you've gone too far

[real thunder]

in what direction

...I guess both

[real thunder]

I got exit time 1 on repeat and on going away from attacking

yeah it repeats attacking instead of going to moving after each attack if player is in range

[scarlet pasture]

so u mean? the Enemy is Attacking conistently?

[real thunder]

if player is near it then yes

it loops attacking

[scarlet pasture]

and u dont want to reapeat the Attack Animation?

[real thunder]

I want it to stop attacking after it finished the whole animation

I don't think I will get an advice here how to make it better...

[hexed terrace]

What calls the attack in the first place?

[real thunder]

protected virtual void AttackLoop()
    {
        if (!animator.GetBool("attack") && animator.GetBool("isAttackEnded"))//attacking stopped go away
        {
            animator.SetBool("isAttackEnded", false);
            agent.avoidancePriority = RegularPriority;
            ChasingEnter();
        }
        else if (isWaitingToGoToTheStunState)//getting stunned
        {
            animator.SetBool("attack", false);
            StunEnter();
        }
        else if (ThinkingIsItWorthToKeepMeleeAttacking() && IsGoodAngleToMeleeAttack())//keep attacking here
        {
            UpdateRotationWhileAttacking();
        }
        else//deciding to stop attacking after next hit here
        {
            UpdateRotationWhileAttacking();
            UpdateAnimatorSpeed();
            animator.SetBool("attack", false);
        }
    }

anyway here is the code

[scarlet pasture]

u will but probobly not the best from me tbh

but i want to help u

[fickle plume]

Manual is your friend. Investigate what is involved in the code and check what members have the objects you are using. You are accessing https://docs.unity3d.com/6000.2/Documentation/ScriptReference/Collision2D.html so look how to access gameObject involved in it, then compare its layer to the one you need. Also examine how to use layers in the manual.

3D

somewhat basic lame FPS

[scarlet pasture]

how long do u devolop Games?

longer than I would want to

[scarlet pasture]

bro dont say that

gamedev is funn

i think

[real thunder]

till you realize you can do anything but it's years of tedious work

[scarlet pasture]

make a small game

i also do one

or do u mean to have the needed skills for a commectial game?

[real thunder]

it's not about commercial it's about general size and pool of content and mechanics

making something big - ton of tedious work

[scarlet pasture]

understand what u mean.

i also try to make a game currently but 2d art kills me so hard. also huge work

i got his!

[real thunder]

the personal problem is better I know that I can do stuff less interesting it is to do stuff

[scarlet pasture]

wait so lose u motivation if u know that u can make stuff?

[real thunder]

yes

learning is fun

doing (what you know how to do) is less fun

[rocky canyon]

knowing and doing are seperate things..
just because you know you can do something doesn't mean you're actually any good at it.. but i kinda get where your coming from

just gotta keep pushing your limits

[real thunder]

I never said I was good tho

[rocky canyon]

time-management is key to that too..
testing, discovery, implementation and so on..

need to arrange it so that the tedious bullcrap.. is in the midst of everything else 🙂

just trying to avoid burn-out i guess u could sum it up as

[rocky canyon]

ohhhh... i know exactly this feeling..

i have a idea

we, yes WE ALL should make a Game... togehter

what do u think?

me as a Leader with 10 ohter guys, we make a new Studio

[tired python]

can anyone tell me how can a Vector3, in this case transform.up be equal to a vector2 type object called direction

[hexed terrace]

it'll just auto put z as 0

[tired python]

would it happen the other way around?

as in if there were a vector2 object and i wanted it to copy the values of a vector3

[hexed terrace]

a vector3 into a vector2? I presume it would ignore z.. but dunno, try it and see

[nocturne kayak]

hello guys i'v made a small script to create a movement but the player is rotating on himself like crazy i guess its from the rigid body but i dont know what to do :)

[rocky canyon]

well for (1) i see two colliders there..

[hexed terrace]

If you're using a rigidbody, don't move with transform.position

[rocky canyon]

for (2) use the rotational constraints on the rigidbody you can lock individual axis

[edgy sinew]

Dynamic and Kinematic Rigidbody have different rules for how to be moved / rotated, to preserve interpolation & simulation accuracy

[rocky canyon]

def get rid of that extra collider whatever route u decide to take

[nocturne kayak]

Thanks everyone, I'll try to fix the problem :)

[rocky canyon]

unless its a trigger or something

[nocturne kayak]

I don't know if it's related to the collider or the rigid body , but my player goes up on its own when the script starts. ( the positions change)

i think its because of the character controller

[rough granite]

Sorry you have both a cc and rigidbody?

[nocturne kayak]

oops

[tender mirage]

Is invoke just the odd child of calling a function but it got an haircut and can't call functions with paramaters?

[rich adder]

the monobehaviour one ? yes its the ugly ducklin

uses reflection to find the function so its also kinda slower

if you want to call a delayed function (that supports parameters too) use Coroutine

[tender mirage]

Oh, i absolutely love using coroutines

[rich adder]

[tender mirage]

lol, but you just made me realize how redounded invoke actually is

shhhh, not you unityevent invoke. You're useful.

[tender mirage]

[rich adder]

the OG Delegate invoke the handy one

[red igloo]

In my game there are small zones where when the player enters them the camera changes to a different one to get a better angle. But the issue is when the camera is at a specific angle the movement input doesn't really match. For an example the player can move around normally when the camera isnt changed but in the image the camera has changed and to move left its S and not A. How do I fix this? should I make the movement camera relative?

[tired python]

where do i need to add this in the following piece of code?

using UnityEngine;
using UnityEngine.InputSystem;

public class Player : MonoBehaviour
{
    public float Thrust = 1f;
    Rigidbody2D rb;

    

    // Start is called once before the first execution of Update after the MonoBehaviour is created
    void Start()
    {
        rb = GetComponent<Rigidbody2D>();
    }

    // Update is called once per frame
    void Update()
    {
        if (Mouse.current.leftButton.isPressed)
        {
            //Calculate mosue direction
            Vector3 MousePos = Camera.main.ScreenToWorldPoint(Mouse.current.position.value);
            Vector2 direction = (MousePos - transform.position).normalized;

            //Have player move in direction
            public float maxspd = 15f;
            transform.up = direction;
            
            rb.AddForce(direction * Thrust);

        }
    }

    private void OnCollisionEnter2D(Collision2D collision)
    {
        Destroy(gameObject);
    }
}

i don't want the object to go beyond a maxspd

[rich adder]

in update like it says

even tho thats pretty cringe

[tired python]

it says after addforce though

[rich adder]

yes after the AddForce. Under the }

this way it corrects any values AFTER addforce was added

[tired python]

wouldn't you want it to be correct before it reaches that state though?

or is it for the next loop

[rich adder]

its happening in 1 frame

usually

[tired python]

yeah, so if i am adjusting it for this frame after it adds the force, then suppose the force reaches 15.1, it already ends up applying it before it gets changed

[rich adder]

15.1 will be corrected right after

[tired python]

what the hell

sdfjsdklfjs

[naive pawn]

the fixedupdate right after?

or what

[tired python]

i can't type

[naive pawn]

isn't accumulated force only applied to velocity upon fixedupdate

[tired python]

so what does that mean?

[rich adder]

Idk why unity wants to put this in update

[naive pawn]

also isn't there a maxVelocity

[rich adder]

but I guess it applies it and then by the physics frame is ready

[naive pawn]

https://docs.unity3d.com/6000.2/Documentation/ScriptReference/Rigidbody-maxLinearVelocity.html

[tired python]

can i tell you guys how i would do this?

and you tell me if that's an aight approach or not

[rich adder]

ops misread that

[naive pawn]

oh cool, physics2d doesn't have it

add it to the pile of discrepencies...

[rich adder]

this looks new to me

I always used Vector3.ClampMagnitude

[naive pawn]

huh yeah wouldn't maxSpeed be more technically correct...

[rich adder]

ya cause its multiplied with normalized so its always gonna be maxSpeed

same thing as doing linearVelocity = Vector3.ClampMagnitude(current, maxSpeed)

[rich adder]

do whatever the tutorial tells you 😛

normally .velocity / addforce do belong in FixedUpdate so idk

[tired python]

what the tutorial is saying doesn't make sense to me, i hoped that by asking here, i would understand...

[arctic scarab]

my unity says that I am trying to read Input using the UnityEngine.Input class, but I have active Input handling? How do I switch?

[naive pawn]

!input

[radiant void]

How to Set Input

To set Active Input Handling, go to:
Project Settings > Player > Active Input Handling

• Input Manager (Old): Use the original Input settings.
• Input System Package (New): Uses the new input system package.
• Both: Use both systems.

[tired python]

like i can blindly follow the tutorial but then, i won't understand what i am doing

[rich adder]

by the next physics tick / game frame you're gonna have the corrected value, then you try to go over, gets corrected again

[tired python]

that's what i was saying though

[rich adder]

its happening so fast practically unnoticeable

[tired python]

thx for the confirmation still

[rich adder]

its basically, why would you add it in the beginning of the frame because then you will have "overflow" value before getting it corrected

[tired python]

does it rly matter though?

like 14.9 vs 15.1 doesn't seem to be a lot of diff

imo

[rich adder]

maybe not always but depends how the tick / frame happened
i always assume its best doing it before the frame ends is best

[naive pawn]

well, across a lot of frames, yes that difference will matter

but with this specifically - i don't think it matters, because it'll all be processed in the simulation step

[arctic scarab]

@naive pawn whats the main difference between new and old and which is more beginner friendly?

I switched to the old one

[rich adder]

Input is more tutorial friendly..
the new input system seems hard but its actually just as easy if not easier

there are just more ways to use it which make it seem complex

[arctic scarab]

ah, okay i'll use the old one for now

[naive pawn]

there is a learning curve to the new system but it's more flexible and imo easier to work with once you understand it

go with whatever the tutorial says for now, worry about this later

[arctic scarab]

alright

[red igloo]

This is what I mean.

[rich adder]

a simple use of new input system
[SerializeField] InputActionReference moveInputAction
Vector2 moveInput
Update(){
moveInput = moveInputAction.action.ReadValue<Vector2>();
transform.Translate(moveInput * speed)

example in the context of a character controller
https://docs.unity3d.com/ScriptReference/CharacterController.Move.html

[arctic scarab]

what in the, i made the movement script, but directions are off, might be the camera tho

[scarlet pasture]

Hey

[arctic scarab]

lemme just rotate it quick

[naive pawn]

yeah you don't have to lead with this, just ask your question straight-up

saves us all a little time

[rich adder]

you need to make it relative to your camera plane yes

[scarlet pasture]

how can i detect that the Player is Moving but not like a extremly small moveinput. Like he is actually moving for a small value. I have this Case => i use a Character Controller!, do Unity have a build in function for that maybe?

[scarlet pasture]

bro i just said hey

dayumn

[naive pawn]

yeah, it was unnecessary

[rich adder]

subtract new position from old position and check the distance ?

[naive pawn]

check the magnitude of the input? im confused, are you trying to implement or counteract a deadzone

[scarlet pasture]

like, i want to detect => "Is the player moving, more than 0.1f?"

[rich adder]

ya or magnitude of character velocity works too

[scarlet pasture]

what is the Syntax of it? can u pls show it to me

[rich adder]

eg
if(player.velocity.magnitude > 0.01) //is moving

[arctic scarab]

I need advice on learning the keywords, for example GetComponent, like how do you memorize what each does? It feels like there is a billion of those words

[rich adder]

always best to use square magnitude though as its faster

[scarlet pasture]

does my Player requiere somthing? like Rigidbody?

[rich adder]

character controller or rigidbody

[scarlet pasture]

what exactlly is that`? and why is it faster?

[tired python]

how do i stop this madness from happening? i am pressing space...

[slender nymph]

press the insert key

[rich adder]

it skips having to do a square root which can save some calculation time, but in most cases it doesnt matter

[scarlet pasture]

and also would it make sense to also check "is the Player pressing A or D" so that somthing cant push the player and the Code thinks the Player is Moving.?

[scarlet pasture]

Thanks for the explanaction!.

[rich adder]

you could do that sure, depends

if you only want to count as moving with keypresses / inputs then go for that

[scarlet pasture]

okay, know i know everthing i need. Thanks Nav and Chris

[tired python]

transform.up = direction;   
rb.AddForce(direction * Thrust);

if (rb.linearVelocity.magnitude > maxspd){
    rb.linearVelocity = rb.linearVelocity.normalized * maxspd;
}
``` added this but this show s a compile error

[naive pawn]

cool, we aren't psychic though. what's the error, and which line

[naive pawn]

alright, you have something wrong above that

[tired python]

wasn't showing these errors prevouisly though

[rich adder]

you missed a { or }somewhere

[naive pawn]

look at where/what the first error is

it sounds like you missed a } on line 23

[slender nymph]

here's a hint: you can't declare public members inside of a method

[rich adder]

oh goodcatch how did I miss that in the screenshot

[slender nymph]

it's in their video when they were struggling with the insert key

[rich adder]

ah yeah you cannot use access modifiers inside of methods

the variables are defaulted to local and dont need access modifiers cause they're scoped (they dont exist outside the method)

[tired python]

then what's this abt

[naive pawn]

you put public float ... in the wrong place

[tired python]

public float maxspd = 15f;

[rich adder]

perhaps it should've been clearer in the instructions but this should be A FIELD not a local variable

yeah most Unity lessons have assumption that one knows basic c#

you never put anything that has access modifiers (public, private etc.) inside methods and are usually fields

[tired python]

give an example

like what can be done and what cant

[rich adder]

public float fieldValue 
void Method(){
float localValue
public float anotherValue // error , we cannot have access modifiers here
}```

using "public" on a local variable would not make sense, they only exists within that scope Method()

hence impossible to be public accessed elsewhere, so we make a field for that

[tired python]

so basically, since the local variable only exists inside the method temporarily, i can't access it...is that the gist of waht you are implying?

[rich adder]

it can only be accessed within that method yes, so access modifiers are not needed.

[short gust]

with Awaitables in Unity 6.0.x - can I assign a lamda function or delegate like with regular Tasks in C# to await them now/later and check for result when I need?
I'm new to async coding in Unity, even though I've used regular C# Tasks before.

[rich adder]

they should be able to be used the same ways no ?

I only used them a couple of times, mainly to switch up a task to be temporarily inside main thread to then do unity API stuff

[red igloo]

Thanks! it was easier than I thought lol

[tired python]

worked out

[rich adder]

like this?

Func<Awaitable> doSomethingLater = async () =>
{
    await Awaitable.WaitForSecondsAsync(1f);
    Debug.Log("Lambda finished!");
};

should work
await doSomethingLater();

soo iirc this wont work
Awaitable a = () => { ... };
but this should
Func<Awaitable> a = async () => { await Awaitable.NextFrameAsync(); };

and ofc you cannot use task specifc methods task.IsCompleted etc

[wintry panther]

Does anyone have a tutorial or guide on how to make kinematicbodies collide with other kinemtaic bodies? im trying to make a 2d car jam game where you drag different shaped blocks (like any rectangle shape or l-shaped blocks) and they are blocked by other blocks

[short gust]

hm, interesting info. thanks!
I suppose they like really similar to Tasks, so I'm overthinking it, hehe

[wintry panther]

i need the blocks to be able to be moved around freely but collide and slide

[rich adder]

yeah I think they tried their best to be as closest possible to task so not to cause friction in usage

I mainly just use when dealing with Unity specific stuff , like I mentioned the Unity events, or switching up backgroundthread thread to main, which is handy with unitys APIs (can only run on main thread)

[rich adder]

maybe try using Rigidbody.Cast (2d)/ Rigidbody.SweepTest (3d)

youd' manually need to detect it and prevent movement manually

[umbral hound]

Why is my rotation so slow? It's at a snail's pace

using System;
using UnityEngine;
using UnityEngine.InputSystem;

public class Ball : MonoBehaviour
{
    private Rigidbody m_Rigidbody;
    private InputAction m_Move;
    public float m_RotationSpeed = 7f;

    private void Awake()
    {
        Application.targetFrameRate = 60;
        m_Rigidbody = GetComponent<Rigidbody>();
        m_Move = InputSystem.actions.FindAction("Player/Move");
    }

    private void FixedUpdate()
    {
        Vector2 vector = m_Move.ReadValue<Vector2>();
        Vector3 movement = new Vector3(vector.x, 0f, vector.y);
        m_Rigidbody.AddForce(movement * (m_RotationSpeed * Time.fixedDeltaTime), ForceMode.Force);
    }
}

[short gust]

I'm trying to achieve something similar. just background processing here and there for some calculations/loading, nothing special. I like that async context can be switched to the main thread by Awaitables API methods, kinda neat thing ngl.

[rich adder]

yeah exactly thats the main selling point for me

[rich adder]

get rid of * Time.fixedDeltaTime

AddForce is already moving on Tick fixed Delta

you're essentially adding it twice

[umbral hound]

oh okay

did not know that, thanks

[scarlet pasture]

hey, i wanted to programm that the backround layer "Moves" with the Player. can i just say Lerp with the Player position but just a little bit slower for each layer?

and if the Player stand, i increase the follow SPeed so the Lerp Catches up faster

i mean is this the Logic behind?

[frail hawk]

are you looking for a paralax effect?

[scarlet pasture]

YEAH! this is what i search better said

is my thought correct? better said my plan?

what do u think?

[wintry panther]

ah okay ill look into that

[frail hawk]

just look for paralax tutorials it is easy to achive.

[scarlet pasture]

yeah, i want to programm first my thought and after asking here. i learn better with this waqy

i mean i can try it why not

[rich adder]

isnt it just different backgrounds at different speeds, in its most simplest form

[scarlet pasture]

so i dont even need to lerp somthing?

[frail hawk]

the z axis is your friend

[rich adder]

I dont think

[scarlet pasture]

nice, i will try it looks easy to me

[rich adder]

some like Movespeeds
background_back = 3f
background_mid = 5f
background_foreground =7f

[queen adder]

    private void OnValidate()
    {
#if UNITY_EDITOR
        EditorApplication.delayCall += () =>
        {
            for (int i = transform.childCount - 1; i >= 0; i--)
            {
                DestroyImmediate(transform.GetChild(i).gameObject);
            }
            if (!debugSheres || vertices == null || spherePrefab == null) return;
            foreach (Vector3 pos in vertices)
            {
                GameObject sphere = Instantiate(spherePrefab, pos, Quaternion.identity, transform);
                MeshRenderer renderer = sphere.GetComponent<MeshRenderer>();

                Material newMaterial = new Material(renderer.sharedMaterial);
                newMaterial.color = new Color(pos.x, pos.y, pos.z);
                renderer.sharedMaterial = newMaterial;
            }
        };
#endif
    }

Why is it so slow to update? The value is being updated quickly but the spheres are updating at maybe 3fps. Is it the fact that I'm creating and destroying gameobjects?

[tired python]

i want this booster to appear only when i left click, but it does not appear when i click it

[scarlet pasture]

maybe because u change the vlaue in the Inspektor and than u dont change the inpektor for a sec. Unity register that and use u OnValidate to Updated it

but im not totally sure.

[rich adder]

because Update doesnt run on Disabled GameObject

[tired python]

it says to make it inactive though...

[rich adder]

the script Player should be on gameobject Player, not on the booster

[tired python]

still not working...

[rich adder]

show the setup

[tired python]

i posted it

[rich adder]

yes but thats the old , show what you changed

[rich adder]

and the Player script?

[tired python]

on Player object

[rich adder]

with the reference assgined?

show

[tired python]

the other things work fine, just this booster

[rich adder]

this doesnt show the reference

expand the script

[tired python]

post the whole thing?

[rich adder]

not the code, uncollapse the Player component

[tired python]

then?

[rich adder]

screenshot

[rich adder]

jesus

do you know what uncollapse means?

[tired python]

i uncollapsed it..

oh wait

its the opposite

[tired python]

oh

wait that actually worked

thx

[rich adder]

hhuh

[tired python]

i was gonna ask, how does the pc know that the booster is the game object

[rich adder]

lol uncollapsing it has no effect , i just wanted to see the reference was assigned

[tired python]

i did not

i assigned it after you asked

[tired python]

was wondering this then saw it not assigned

[rich adder]

oh exaclty, did you not check console probably spammed a few Null Reference Exception

usually first place to look when its not working

keep the Console window visible

[rich adder]

mhm yeah thats why assignment is important

[scarlet pasture]

u also can use Error Pause, so its frezzes the Game if u have a null reference

[tired python]

the guide told me to use this layout...

[tired python]

ya that too, but i don't have the console window visible so....

[rich adder]

the layout is fine just make sure you pop the Conole tab somewhere visible, its pretty important

its hard to catch the messages if they are just a footer of the app

[scarlet pasture]

if u have Error Pause u dont even need to open the Console Window

but its better if u check it out if u start the game

[rich adder]

I mean you still wanna keep the console there open at all times

thats your lifeline to the "backend"

[tired python]

can't i use the UI thingies which the project inspector and other tabs use?

[rich adder]

drag the tab where you want it

no need to undock it

[scarlet pasture]

u can do this

make them into one, it saves space

[tired python]

thing is, i can't get it to work the way the other tabs do

[rich adder]

yeah but then its not open at all times especially with Project view

best to keep it there

eg hers mine

[tired python]

nvm

got it to work

you guys have massive screens

[rich adder]

i'm on a 13 inch macbook

[scarlet pasture]

what game are u making?

[tired python]

this ain't massive

[rich adder]

nothing rn just testing random crap

trying to finish this I started a few months back

[tired python]

nice

[scarlet pasture]

Fire On God

[twin pivot]

Its very retro

[tired python]

the mouse showing is a bit eee though

[rich adder]

ya it was a 1 bit jam but ended up missing out on the deadline so Im gonna make it a smaller game

[tired python]

i remember wizard legends using a similar thing, didnot like it

[rich adder]

debug mostly

[queen adder]

Is there some sort of standard to creating a square mesh for procedural terrain?

vertices[x]     = new Vector3(0f, 0f, 0f);
vertices[x + 1] = new Vector3(0f, 0f, 1f); // z first
vertices[x + 2] = new Vector3(1f, 0f, 0f);
vertices[x + 3] = new Vector3(1f, 0f, 1f);

vertices[x]     = new Vector3(0f, 0f, 0f);
vertices[x + 1] = new Vector3(1f, 0f, 0f); // x first
vertices[x + 2] = new Vector3(0f, 0f, 1f);
vertices[x + 3] = new Vector3(1f, 0f, 1f);

Is one better than the other? Am I overthinking this?

[shell sorrel]

as long as the winding direction is correct it does not matter

and that part is done in the trinagle array anyways

[queen adder]

alright

fair enough

[shell sorrel]

https://docs.unity3d.com/2021.2/Documentation/Manual/AnatomyofaMesh.htm

the 2 triangles to make the quad should have things winding in clockwise

[dreamy scaffold]

Can someone help me with this error? I have already tried deleting the library and regenerating my project files, but nothing seems to fix it

Any help is much appreciated

[shell sorrel]

show the code that caused it

also you do not want to be using the UnityEditor namespace in your game logic code

[dreamy scaffold]

I just realized that was the case...

Nvm it looks like it is able to build now, ty for the help. I completely missed that for some reason.

[shell sorrel]

yeah builds will fail if UnityEditor namesapce is used in logic that makes it into the build

its only around while in editor

[rich adder]

Unity basically strips those when you build

[swift crag]

this often happens when your IDE gets a little too helpful and adds a using directive when "fixing" a typo'd name

shoutouts to this one in particular

[chrome apex]

stupid question, is there a way to look at a transform or collider of an object while moving another object in scene view?

[shell sorrel]

can change one of thse options to give it a icon or show a name in scene

[swift crag]

You can right click on an object in the hierarchy and hit Properties... at the bottom

This will open a new inspector panel that displays that object

You can also lock the inspector to prevent it from switching to another object

[shell sorrel]

that works as well

hmm actaully collider gizmos only show for selected

does not matter if it still has a inspector focused on it

i have before jsut added a component that literlaly just draws gizmos then removed later

[chrome apex]

but I need to move the other object via the transform arrows.

[scarlet pasture]

u can use 2 Inspektor, i think...

[swift crag]

The handles will appear on whatever object is actually selected.

[charred spoke]

alt shift p also pops out a locked version of the inspector for the selected object

[swift crag]

ooh, handy!

[charred spoke]

Changed my whole unity experience when I learned this 🤣

[chrome apex]

sorry, I didn't mean inspector, I wanna look at it's collider or transform arrows in the scene view

Guess I can just open up another scene view

oh wait,

I can do it the other way round

[scarlet pasture]

hey, i want that the leaves fall out of the tree, for a better atmosphere. isit normal to just instaitate them and use the Animation for each Leave?

this would be bad for performance right?

[chrome apex]

I can lock the inspector of the first object and instead of moving it with the scene view arrows, I move it via the transform component and have the other one selected

[swift crag]

That sounds like a job for a particle system!

[charred spoke]

Very bad yes

[scarlet pasture]

.... i have sprites of the leaves....

[charred spoke]

A particle system is what is usually used for this kind of thing

[charred spoke]

Perfect

[polar acorn]

Yeah, probably

It'd be weird if you didn't

[charred spoke]

I’ve done leaves with meshes as well

[scarlet pasture]

if i use a particle effect, would that also allow to animatie the leaves?

[swift crag]

Yes, you can do quite a few things!

You'll want to plug the Sprite assets into the Texture Sheet Animation module of the particle system

[shell sorrel]

with the write sheet layout you can even randomly choose a row and animate across it over lifetime

[scarlet pasture]

and what would be the dirffrence? between a normal Animatiatead leaves and a Particle System Animated leave

[swift crag]

your game wouldn't be full of hundreds of tiny game objects :p

particle systems also make it very easy to create a variety of effects

[shell sorrel]

particle system is greatly more effecient and can do huge numbers of that at little cost

[swift crag]

e.g. wind, collision with surfaces, fadingi n and out

[shell sorrel]

and isntead of hand animating you can apply forces and noise

[swift crag]

they're incredibly useful (i mostly work in VRChat right now, and you can pull off a ton of stuff without any scripting)

[scarlet pasture]

Thanks i will try it

[shell sorrel]

in almost all engines its like the stadard way to handle, smoke, sparks, leaves, dust, rain, snow etc

[wintry panther]

im using a kinematic rigidbody and calling movePosition() and detecting collisions manually, but when the object detects a collision with another kinematic rigidbody there's slight gaps between them. does anyone know how to make pixel perfect collisions?

but im not sure this woul work

Hey! Just quickly looking to work out if something like this infinite zoom effect should be done with some kind of visual shader, or a script to warp the geometry? My plan was to have the player be stationary where they only orbit the center at a fixed distance, then scale up the geometry, but looking at the center, it scales up really fast, then slows down when approaching the player. Thanks! https://www.youtube.com/watch?v=4sAft1zecHk

my Goal is to make a Scalable Combat System for a 1-3 Month Game.

[swift crag]

To get a smooth scaling effect, you need to do exponential scaling – the rate of change is proportional to the current size

so, if your current scale is 1, you change twice as fast as when the scale is 0.5

this means that it takes a fixed amount of time to double in size

if you just add to the scale at a uniform rate, each doubling takes twice as long

I'd consider calculating the scale directly with a function like this

float startScale = 0.01f;
float startTime = 0;

void Update() {
  float lifetime = Time.time - startTime;
  transform.localScale = Mathf.Pow(2, lifetime) * startScale * Vector3.one;
}

this doubles once per second, so it'll reach a scale of 1 after log2(100)=6.6-ish seconds

If you need to start out at zero scale, you can lerp in from zero

Mathf.Lerp(0, 0.01f, lifetime);

this would go from 0 to 0.01 over the first second

[twin ember]

I see, in the past I have created similar effects in Blender (https://www.youtube.com/shorts/S15PC1Itmw8), though I'm not sure if this is different where the walls spawning at the center seem to grow really rapidly, kinda like a pinch filter. I assume an effect like this would need to go on the verts rather than the entire gameObject's scale, moving verts closer to 0 0 0?

[swift crag]

(and then stop growing, because lerp is clamped)

[twin ember]

This seems to show the tin on the left totally warping like a central vanishing point drawing

[swift crag]

That might be better done in a shader then, kind of like how you'd do a curved world for an infinite-runner game

Each vertex is getting scaled down separately based on its distance from the origin

[twin ember]

Ah interesting, yeah. So I would create a shader for some GameObject that adds walls and floors on a simple exponential scale/zoom, then warp the center of the object with shaders? I'm sorry, lack of knowledge for implementation of the two combined here

[swift crag]

You want the obstacles to actually change in size over time, so that they can bump into the player. So you might wind up doing both:

• Each object starts with a tiny scale and grows exponentially over time
• The shader shrinks vertices on the Y axis based on their distance from the center

So, for example, the "pizza slices" in that screenshot would actually have a uniform height – like a slice of cake

but the shader would then squish them into a wedge shape

[twin ember]

OH that's a good idea, so then the pinch effect is purely Y scaling from the shader, which seems like a really good approach. Thank you!

[swift crag]

So you'd start out just scaling up objects, then throw in a shader graph that does something like this:

• measure the distance from the world origin
• remap that into the 0..1 range (maybe just use Inverse Lerp + Clamp; i forget if there's a remap node)
• multiply your world-space Y position by that

[twin ember]

Sounds like it actually isn't as hard as I expected, tysm, I'll give it a go

[swift crag]

no prob (:

[glad shore]

how do i get the main parent of a gameobject

[polar acorn]

.transform.parent

[glad shore]

but that gets the parent of the object, i want the main parent even if its being held by multiple parents

[rich adder]

transform.root

[tired python]

UI related topics go into #📲┃ui-ux right?

[glad shore]

i cant believe i have just found out this exist 😔

actually fixes all my problems ✌️

[polar acorn]

Ah, wasn't sure what you meant by "main parent". Yeah that's root

yeah, i was looking for a way to get the topmost parent in the hierarchy. I was trying to organizing my hierarchy way more without it

[scarlet pasture]

sorry, i said to him, "Can u pls rate my Code and give me some Tipps, i want to be a better Coder"

[eager elm]

for starters don't suffix your script instances with 'ScriptRef'. Lots of magic numbers in your Update method, why 0.22 and 0.27? Define them somewhere so they have a name.
And a lot of stuff in a single script. Shooting and Melee should probably be in two separate scripts.

[scarlet pasture]

what is a megic number?

okay i will try to have to make them in seperate Scripts. Thank u bro!!!!

[eager elm]

the numbers in your Update switch statement like 0.34. Only you know what they are supposed to be. You should define them as variables at the top so it's clearer, like, I am assuming:
float cooldownRecoveryTime = 0.34f;

[scarlet pasture]

ahhhh yes i already habe this, in the Variabels u can see "useOptionalTimers"

so i can defint the float values if i want

[charred monolith]

looks great and very clean!

[scarlet pasture]

bro wir müssen englisch reden. Thanks bro, try to improve my Skills.

[zenith wren]

what is causing this to happen? None of the errors take me to a specific block of code

[grand snow]

known editor bug, deselect and re select and pray it works.
update your editor to fix it (should be fixed now)

[zenith wren]

ah I see

at this point contemplating to just transfer everything to 2022 version

[grand snow]

do not do that, just update to the latest 6.0 version
downgrading major version will probably fuck your whole project

[zenith wren]

ah I see

Hi guys! I'm new to game developing and I wanted to practice with some of the most famous softwares so I chose Unity bc I heard that it's good to get started and do simple stuff. I'm also new in coding in general and I wanted to know which tutorial did you use to learn Unity, any advice you can give me from personal experience etc would be well accepted, thank you and see ya

hey i joined this server just now so i could get some help with a game im developing. its a 2d game and its in its early stages, right now im looking for help with programming a wall jump. could anyone help with that?

sure, just provide the necessary information when you !ask the question for others to help . . .

How do I connect visual studio to Unity? Unity classes are not highlighted

Do you mean which application you want your scripts to be opened in to be vs?
it should be in settings > preferences

Hi! I am creating a package and I would like that, after installing it, the system changes automatically (or prompts the user to change) the Active Input Handling setting to "Both" instead of only using the old input system. I've tried looking this up but I haven't found an answer. Any help is appreciated!

[grand snow]

I know android doesn't support both so its unwise to want this (unless this is for specific platforms you know support both). You can use conditional compilation to support both input systems.

[pallid linden]

I'm developing for windows for now, so that should be fine 🙂
Someone tried to install my package and it didn't work because their unity client had it by default as the old input system. What's weirder is that he had to restart 2 times after changing the setting to "both" for it to take effect. That's why I would like to change it automatically if possible!

[grand snow]

I cant see this as something that can be changed in code. Some things just aren't. You could just edit the file directly but may cause issues

[fast relic]

you can use conditional compilation to check if the new input system is enabled (#if ENABLE_INPUT_SYSTEM), and if it isn't, prompt the user to change it i imagine

[vast comet]

Hey, I was wondering if its possible to avoid these cracks between rails, using Unity's spline instantiate. If I make the rails more frequent, it wont be smooth.
Any way to make procedural rails?

[pallid linden]

Okay, thanks!

[pallid linden]

I think I will try this then. If it cannot be changed automatically, I will make a prompt to tell the user to change it himself. Thanks for the snippet, that will come handy!

[fast relic]

you can probably also add a button to open the player settings window if you're fancy

[pallid linden]

I found that I can use this:

bool openSettings = EditorUtility.DisplayDialog(
    "Enable Both Input Systems",
    "This package requires Unity's Input System and the old Input Manager.\n\n" +
    "To avoid input issues, please open Player Settings and set\n" +
    "Active Input Handling to \"Both\" under 'Other Settings'.",
    "Open Player Settings",
    "Later"
);

if (openSettings)
{
    SettingsService.OpenProjectSettings("Project/Player");
    Debug.Log("Go to 'Other Settings → Active Input Handling' and set it to 'Both'.");
}
else
{
    Debug.LogWarning("Active Input Handling may not be set to Both. " +
                     "Some input features might not work correctly.");
}

[fast relic]

yeah that should work

[grand snow]

cant wait for most things to ditch the old system

[fast relic]

i think the issue they're having is that some people have it set to old and not new?

sorry if i'm misunderstanding

and it didn't work because their unity client had it by default as the old input system

[grand snow]

yea, only recently will new projects default to input system.
But having both be around isnt great especially if you want to target a platform that cannot use "both"

[fast relic]

yeah the new input system is ideal to use but i can understand people either being stubborn or legacy projects that are a pain to migrate

[pallid linden]

That's true!

I think it's about time to use only the new input system

[fast relic]

definitely yeah

[pallid linden]

Also, a bit off topic but why do we still have to install TMPro as an extern package?

Shouldn't it be Unity's default?

[fast relic]

i never had to?

[grand snow]

Nah in unity 6 its inside unity ui

but before it was its own package

[pallid linden]

But even in Unity 6 I get the prompt "you need to install TMPro essentials"

And I think that the "Text" class is still different from TMPro

Shouldn't they be like unified by now?

[fast relic]

that's not the package itself, it's juwst some resources that tmpro needs to be in your project

[pallid linden]

True

[fast relic]

probably so you don't have extra stuff clogging it up if you don't wanna use tmpro (ui toolkit or legacy text)

[fast relic]

yeah it's a legacy thing

[grand snow]

ugui Text is the legacy one

and tmp essentials is needed to add some shaders and stuff

if using UGUI you want tmp, legacy text is poo poo

[pallid linden]

I haven't seen a single project using legacy text, they all go TMPro so that's why I wondered why it wasn't just replaced by that

(at the same time I'm not that experienced so I cannot say I know much)

[fast relic]

legacy compatibility i imagine

so that if you're migrating an old project that doesn't use it it doesn't just break completely

[pallid linden]

That makes sense

[fast relic]

but tmpro is the one that should be used

[night raptor]

I haven't used the spline package myself much but I don't think you can get away with just instantiating blocks on the spline. Even if you make the blocks be closer, the transition won't obviously be perfect. I would rather make the spline by repeating and actually deforming the rail and then instantiating these parts separately (assuming it is not possible to do that directly with the package, I don't know)

[grand snow]

Its somehow not functionality offered by the splines package

[night raptor]

what isn't? (just asking)

[grand snow]

they do have some mesh generation stuff (inc a road) but nothing to deform a mesh along a spline

I feel like the ideal solution for a railway track would be mesh extrusion along a spline

[night raptor]

Oh unfortunate. Maybe should use one of the countless spline assets out there then that support that, the unity one might not be great then

Yeah, I mean of course making your own mesh generation using the unity splines isn't horribly difficult to do though

[night raptor]

The spline package sample Extrude Spline and Nearest Point seems to do that by using a separate spline for the profile and extruding that along other spline. That is probably not optimal but should get a rail done

[grand snow]

hmm yea that sounds like a decent option 🤔

[hexed terrace]

This is a code channel. Delete and ask in #📲┃ui-ux -> with screenshots of your setup

[remote mountain]

ok

[tired python]

so i set the restartbutton to be invisible when the game starts.

and be visible only when a collision happens

but somehow, the restart button keeps appearing at the start

[wintry quarry]

Debug.Log to see if the latter is running at the beginning of the game

It's a little odd though - which script is each of these snippets from and which object is that script attached to?

[tired python]

void OnCollisionEnter2D(Collision2D collision)
{
    Destroy(gameObject);
    Instantiate(ExplosionEffect, transform.position, transform.rotation);
    RestartButton.style.display = DisplayStyle.Flex;
    Debug.Log("Restart Button is Displaying.");
}```

Like this?

[wintry quarry]

I would do it as the first line

Not the last

[tired python]

oh wait

i don't think that's the problem, cus the explosion effect doesn't play unless a collision occurs

[wintry quarry]

Check anyway

[tired python]

only displaying it when collision occurs

[wintry quarry]

Ok so back to this question

[tired python]

lemme check

[wintry quarry]

Because from that error it looks like you don't have a valid reference set up

[tired python]

the script is the PlayerController script and the object it's attached to is the Player

[scarlet pasture]

u only want to kill the player if he is colliders with the rocks?

[tired python]

yes

[scarlet pasture]

if yes u should also make sure that u only allow collisions with spezifical Objects

[tired python]

not for now...

the tutorial only tells me to destroy it whenever it collides with any objects

even the outline

i will get to it once i complete the tutorial

i don't want to end up messing the code and then resulting being stuck to find out what i did wrong

[scarlet pasture]

did u maked sure that the Ui is visible to false befor the game starts?

[tired python]

here

[scarlet pasture]

hmmm im also new but can u share a picture of u player? and all of his child objects?

because right know u allow collisions with everthing, if u have a chiled or somthing in the scene thatz does have a collider u run the onTriggerEnter Method.

[scarlet pasture]

under the player have this colliders?

[tired python]

well, i am not really in a position rn to tinker with stuff the tutorial told me to do

once i get through this, i will do that

[scarlet pasture]

u can do that but u problem is that the restart button apears even u didnt collide with the rocks

u have child GameObject with a collider?

[tired python]

yes

[scarlet pasture]

yes or no?

[tired python]

yes

it's called rb

[scarlet pasture]

rb? is rigidbody2d

[tired python]

``Rigidbody2D rb;

[fast relic]

imo that's a really bad mentality actually - you should tinker with stuff tutorials tell you to do - that's how you learn

[scarlet pasture]

i mean "Collider"

if u child has some Colliders => "u player collides with them and this run the trigger methode"

[tired python]

nah, i don't think i have it rn

[scarlet pasture]

go check it out

[tired python]

these are the basics i am learning though, i don't wanna end up adding smth and then stop the code from working altogether

[scarlet pasture]

u see, this is a collider2d if any of u Childs have this u trigger metod runs if u child has "Is Trigger" to true

[tired python]

what should i look for?

[fast relic]

yes you do, you'll learn much more if you do that

the goal of a (gamedev) tutorial is not to get a game out of it, it's to learn how to make games yourself

[scarlet pasture]

look under u players child object and just make sure.. have the objects a collider?

[tired python]

wait a sec

[tired python]

i set up the is trigger to true in the inspector window for the three objects

[tired python]

they do have a collider otherwise it would not be exploding rn when colliding with stuff

[scarlet pasture]

yeah but i think if u have the child objects a collider and "isTrigger" is setted to true u trigger event runs

i wish i had better englisch skils, i think i would understand everthing better.

[tired python]

can you give me an example for it...

[tired python]

it's also possible that i am the problem

[scarlet pasture]

nahh bro

[tired python]

bruh i am new tooo...

[tired python]

what's the trigger event?

yes i did do that

[scarlet pasture]

to the childs?

not the player! the childs!!!

[tired python]

childs

[scarlet pasture]

okay

u code is thinking i "Collides with my self" so i need to use my Trigger code and make Ui visible

[tired python]

ok...

[scarlet pasture]

IM NOT SURE, im really not the best but u need to make sure that u only allow collision with spezifical objects

[tired python]

i do get what you are saying, currently the code destroys the object for every 2d object it collides with, i would want the object to only destroy if it collides with certain objects...

[scarlet pasture]

other is the name! of the function

if.other... (that mean if this script lies on the player!!!!, detect is somthing collides with ME!#

i want to detect gameobjects and i want to compare my Tag with the other tags. if they have the Tag "Rocks" run my code

my tag is as a example "player"

and the stuff that should kill me have this example this Tag

bro sorry... im to bad to explain somthing....

[rugged beacon]

theres collision matrix to exclude collider collide in different layers

or the include exclude box in the collider component

[scarlet pasture]

yeah but he dont want to ignore them

i think he is currently colliding with him self, and he dont have a safty check befor the "Ontriggerenter2d" code runs

[tired python]

so basically, you want to check for whether the object has a certain string in it, in this case "Rocks", and if it does, the collision occurs?

[rugged beacon]

its the same as you doing if(tag) then execute

[tired python]

i ain't colliding with myself...

the game runs, problem is the restart button ain't working

[scarlet pasture]

but u had child that has a collider and a trigger??

[tired python]

they did not have trigger

[scarlet pasture]

oh

[rugged beacon]

this your player? every child has a collider?

[tired python]

i only did that because you told me to...and after i did check the trigger for the child objects, my spaceship started to go trhough them and not explode

[scarlet pasture]

no i just asked do u habe enabled the istrigger#

i didnt said u should do that

[tired python]

i did not have the trigger enabled xD

[scarlet pasture]

good

[rugged beacon]

are the child overlap themself ?

[scarlet pasture]

so u only problem is that u restart button are not working?

[tired python]

meaning?

[scarlet pasture]

what is not working`?

[tired python]

it appears at the start, not when i collide

[rugged beacon]

triangle or square there in your player, are ther collider touch each other, if yes then your player is colliding with itself

[scarlet pasture]

AND u are 100% sure that now any of u child has a trigger AND istrigger is false

[scarlet pasture]

this is what i try to explain, but my englisch skills are hella chopped

[rugged beacon]

idk brother same

[scarlet pasture]

looks fine to me

[tired python]

the restart ain't fine

[scarlet pasture]

where is u ui gameobjects?

better said what controlls u ui?

what Script controlls u UI*

[tired python]

are you asking for the script?

[scarlet pasture]

yeah

[scarlet pasture]

this also controlls the restart button right?

[tired python]

yes

[rugged beacon]

the code inside the script?

[tired python]

yes

[rugged beacon]

i mean can you show it

[tired python]

should i post it?

[scarlet pasture]

maybe u coded somthing wrong can u post it

[rugged beacon]

brother yes pls

[tired python]

this

[rugged beacon]

void OnCollisionEnter2D(Collision2D collision)
{
Debug.Log("Restart Button is Displaying.");
Destroy(gameObject);
Instantiate(ExplosionEffect, transform.position, transform.rotation);
RestartButton.style.display = DisplayStyle.Flex;
}

can you try comment this out? see if the collision the problem here

this happens when i comment the whole thing out

how is it still showing up

[rugged beacon]

well you see, its already show up

[tired python]

exactly

[rugged beacon]

its not about the collision

[tired python]

yes...where did i go wrong

[rugged beacon]

your reference is wrong maybe then

[tired python]

RestartButton = UIdoc.rootVisualElement.Q<Button>("RestartButton"); this thing?

[rugged beacon]

i think so, debug log the button see if its null

i havent done uitk before

[tired python]

it does print null when i collide...

[rugged beacon]

check your naming and stuff

[scarlet pasture]

can u show what error u get

[tired python]

yes, it does show null reference error

[scarlet pasture]

so maybe u code dont find the ui

can u show the error log

[tired python]

prolly naming problem

[thorn holly]

That’s ur problem

What’s the null ref

[scarlet pasture]

click there two time and see to what lines it brings u up

u didnt assing somthing

[rugged beacon]

its the button

[tired python]

Player

[scarlet pasture]

defintely

[rugged beacon]

brother fix your button reference

naming and stuff

[scarlet pasture]

S1nth did u clicked two times at the references, it should opent the code and shot to u eactly whitch line dont functioned

okay nice now opend the player and look

whitch variabel u need to assign

i think this can be the problem

[tired python]

private Button restartButton; it's private

i can't access it through player

it doesn't show restartButton in the list

[thorn holly]

Add a [SerializeField] on top to access it from the inspector

[rugged beacon]

you said this thing is null, that means this line here fail to get the refernce

check if the right side thing correct

[scarlet pasture]

s1nth

[tired python]

what name should the thing inside " " have

[rugged beacon]

idk havent done UITK before, did you not know what to put in there in the first place...
try rewatch the guide you follow

[scarlet pasture]

me too

[tired python]

RestartButton = UIdoc.rootVisualElement.Q<Button>("RestartButton"); just tell me what name is the "RestartButton" supposed to refer to?

[rugged beacon]

what ever name in your ui doc

[tired python]

where is that at?

[rugged beacon]

... please rewatch and understand the guide you follow

[tired python]

oh wait, that's PlayerController.c

found the problem, this thing is what is supposed to be in that string

RestartButton = UIdoc.rootVisualElement.Q<Button>("Button");

it's working

thx guys

@rugged beacon @scarlet pasture

[rugged beacon]

type shi

[tired python]

i want to add the functionality of the total energy being conserved before and after collisions so that the momentum of individual asteroids doesn't die out...

any ideas as to how i should do it?

it's not in the tutorial...

[thorn holly]

So like the ship explodes and the asteroids keep going?

[tired python]

that does happen but that's fine with me, it looks good. suddenly pausing everything would seem awkward

what i do want to happen is that, after a bunch of collisions, the momentum of the asteroids dies out, and then they come to a stop

[thorn holly]

Wdym “a bunch of collisions” don’t they only collide with the player?

[tired python]

they collide with each other and the boundary

[scarlet pasture]

u mean when two rocks collides ther bounce of and lose the energy for moving?

okay i think u only need to give the rigiobody a bouncy value heigher then 1

but im not sure, like i said im also new

[thorn holly]

Make an on collision enter 2d for the asteroids and decrease their linear velocity when there’s a collision, or you can use physics

[tired python]

i will try it then

[thorn holly]

The other option is to make a physics material with a bounce of LOWER than 1

Which is prolly simpler tbh

I’d do the physics material

[tired python]

lower than 1 or more than 1

[thorn holly]

Lower

[scarlet pasture]

in the interent u can see other people solve this provblem with code

but its very hard, they use a mathimatical way

[scarlet pasture]

my bad sorry, i thought u need to make it heigher

[tired python]

i don't want the collisions to die out

[scarlet pasture]

    {
        var rb2 = c.rigidbody;
        if (!rb2) return;

        Vector2 n = c.GetContact(0).normal.normalized;

        float m1 = rb.mass;
        float m2 = rb2.mass;

        Vector2 v1 = rb.velocity;
        Vector2 v2 = rb2.velocity;

        float u1 = Vector2.Dot(v1, n);
        float u2 = Vector2.Dot(v2, n);


        if (u1 - u2 <= 0f) return;

        float u1p = ((m1 - m2) * u1 + 2f * m2 * u2) / (m1 + m2);
        float u2p = ((m2 - m1) * u2 + 2f * m1 * u1) / (m1 + m2);


        Vector2 v1p = v1 + (u1p - u1) * n;
        Vector2 v2p = v2 + (u2p - u2) * n;

        rb.velocity = v1p;
        rb2.velocity = v2p;
    }
}```

they used this.. waht ever this is 🥀

[thorn holly]

Wait what? You said you wanted the asteroids to slow down and eventually stop when they collide

[tired python]

no..i said that that's what it happening

i don't want that to happen

[scarlet pasture]

no he mean that if they collides (the rocks they never stop moving) and lose the energy

i think...

[thorn holly]

Oh in that case make a physics material with a bounciness of exactly 1

[tired python]

bro, those are conservation of linear momentum formulas in code

[scarlet pasture]

🥀

what

[tired python]

oof

[scarlet pasture]

is that not default?

[tired python]

i think it's this formula that they are trying to replicate using code

[scarlet pasture]

Helllll nahhh bro forget to asing a value but know this shit

[thorn holly]

No

[tired python]

the variable names match

[scarlet pasture]

🥀

[thorn holly]

That’s really unecessary, unitys physics does it for you

[tired python]

ya, that's what i think too

[scarlet pasture]

yeah he is definetly right, the code looks also very hard to understand. for me tbh

[thorn holly]

Just use a physics material with bounciness of 1, make sure you set bounce combine to maximum

Then add it to ur asteroids

You could also set friction to zero and friction combine to minimum to ensure no energy is lost from friction

[tired python]

how about you try coding it out, it won't look that bad. the formula isn't that hard to understand tbh

ofc, you wouldn't be using it but u know, if it fascinates you...give it a shot

[scarlet pasture]

definetly

and im 100% i will need that in the Game Devolopment in the future

for nice levels i think

[scarlet pasture]

S1nth?

are u also new?

[tired python]

yes

i mean...kinda depends on what you call new. i am new compared to most people in here soo....

Hello everyone, I've got a silly beginner question for you all. I'm trying to have a class with the following property:

private string[] cubeState { "one", "two", "two", "one", "two", "two", "one", "two", "one", "one", "two", "one", "two", "one", "one", "two" };

Based on my readings that is not possible, I need to do something like this :

public string[] cubeState { get; set; }

and then assign / edit values later...

cubeState =  new string[] { "one", "two", "two", "one", "two", "two", "one", "two", "one", "one", "two", "one", "two", "one", "one", "two"};
cubeState[4] = "two"

I just wanted to check, is this really the only way? I spent time reading and couldn't confirm if I had other options?

[vital barn]

public string this[int index] ???

[maiden drum]

Is there any way to add a contructor to monobehaviours before initialization?
I hate adding an Init() function after because i can see myself forgetting to call it, and it increases implicit knowlage. Same for manually adding the variables.

There's the possibility of adding an alternative instantiate function for the objects, but i'd rather not if there is an easier solution

[thorn holly]

So wait what are you trying to do? Initialize the array when you declare it?

[vital barn]

No

[low copper]

Sorry I don't understand

[low copper]

Yeah, I guess that is what I'm trying to do

[vital barn]

this is an indexer to refer to its class as an array.

[maiden drum]

private string[] cubeState **= **{ "one", "two", "two", "one", "two", "two", "one", "two", "one", "one", "two", "one", "two", "one", "one", "two" };

you forgot the =

if you just want an array with certain values

[vital barn]

I didn't understand the question lol

[maiden drum]

i think he's trying to initialize an array with values

[low copper]

oh...so it does work! Yep, that I wanted. I

I could have swore I tried that and got errors. Thank you!

[maiden drum]

np mate

[low copper]

For your question...none of the Monobehavior methods work for initialization? Awake() or Start()?

[maiden drum]

nah i meant adding a required argument, for example Bullet(speed, damage, whatever)

unfortunately you need addComponent / instantiate and then either assign the values or add an init() functions, can't really add required params

[vital barn]

The only alternative is to have your own shell over the component system.

Or a method that accepts generic interfaces

[maiden drum]

yeah, i think just add a wrapper for the objects that i want to force arguments on.

Essentially i want weapons to pass the bullet stats SO the the bullets they pool/instantiate, since i'm reusing the same prefab for multiple weapons. And i can see myself forgetting inits() when writing new weapon scripts in the future

when i'm thinking about it, probaby a base class would be enough, there won't be neccessarily any bullet creation logic changes between the weapons,

[vital barn]

But to be honest, the need for Inits methods is not even a problem.

[maiden drum]

why?

How would you solve instantiating prefabs / adding components with different values?

[low copper]

@maiden drum : Sorry if I'm just wasting your time...I'm pretty new to all of this...but maybe you could do an abstract class that grabs the bullet data for that particular game object from some data source

and just extend off it

[vital barn]

Init is already a solution to the problem, and MonoBehaviour's lack of constructors is simply the need for an engine to use serialization.

[maiden drum]

i'm thinking of doing something along the lines - just have a base class with methods shared across weapons, one of them being the bullet creation logic + stats "passdown" and every additional weapon script can just call the base class's function

[maiden drum]

kinda agree, just need to be careful not to forget to call it, lest you have errors.

Just from a testability / implicit knowledge POV.

But yes, they do solve the problem

[tender mirage]

StartCoroutine returns Coroutine handle use it or call StopAllCoroutines

[cosmic dagger]

Use an interface, it'll require you to have an Init method . . .

[tender mirage]

Yeah, i used StopAllCoroutines, but why doesn't stopCoroutine work?

[vital barn]

It heed coroutine handle

[tender mirage]

You mean the Keyword Coroutine?

[vital barn]

Which is returned by StartCoroutine

[vital barn]

class Coroutine

In UnityEngine

[vital barn]

yes

[tender mirage]

So something like this?

[vital barn]

Yes

[tender mirage]

yeah. not used to using that. i need to learn it

thanks for the help

also fumo.

I meant forcing the creator to call init() / having it part of the argument.
Not interfacing the definition of Init()

(unless i misunderstood what you meant)

[cosmic dagger]

If you have more than one instance of the coroutine running, it doesn't know which one to stop. By using a Coroutine handle, you are telling it specifically which coroutine you want to stop . . .

i have a question, i have two collision effects. First one for when my player object collides with other 2d objects (resulting in it being destroyed) and second one for when other 2d objects collide with each other ie asteroids with each other or asteroids colliding with the background. I want to add an effect for when the latter happens. How do i set it such that when certain objects collide with each other, a specific collision effect occurs?

[vital barn]

Use tags

[tired python]

i don't know what they are, got a guide?

[vital barn]

Google

[tired python]

wait, that does not make sense

ofc i am going to use a diff tag for diff collisions

my question is, how should i code it out in a way such that only when certain 2d objects collide, does a specific collision effect happen
