A bit late to the discussion, but I feel having both an SO and a prefab (multiple of each) kinda defeats the purpose. At that point you can just have the prefabs and prefab variants. 🤷‍♂️

tyty

so i'm trying to make something where if the player walks into the range of an item, they can press "e" to pick it up, here's my code can someone please help? here's my code https://paste.mod.gg/pmhtzbddblyq/0

[frail hawk]

you would have to use OnTriggerStay in this case or use a boolean as trigger

something like inRange true OnTriggerEnter and !inRange OnTriggerExit

[sharp bloom]

The way you have it written is that you have to press "E" the exact millisecond when you enter the item range

[lapis parrot]

Oh no

[lapis parrot]

can you send a unity link teaching boolena

booleans

[naive pawn]

it's not a unity thing

[frail hawk]

booleans can be true or false, in yourcase you simply declare the boolean at very top so it is reachable from the OnTriggerEnter and OnTriggerExit

[naive pawn]

it's a general programming thing

[lapis parrot]

at the top would i just bool A true; bool B false;

im confused on how'd i'd implement that

[frail hawk]

you will have to learn some c# mate

nothing to worry about, we all had to do it, you can do it too

[lapis parrot]

[acoustic belfry]

hey, i dont know why my enemies after i turned them into StateMachines walk backwards and they display their shooting animation instead of patrol animation, i specify the StateMachine thing cuz this means the external functions work well

https://paste.ofcode.org/tCf4yV5VQReBjB7TkvbKt6

[rocky canyon]

are you in the correct states? have u debugged and tested with validation?

[acoustic belfry]

i mean, it would be weird if it mixed states but i will try it now

[rocky canyon]

in mortemtrooperChase() ur always calling dispararmortem()) and playing "mortemrifleshooting" even when enemy is chasing and not in firing range

[acoustic belfry]

huh? im?

ou

[rocky canyon]

and ur sight logic may just be backwards as wel

[acoustic belfry]

aaaa, chase

but thats not the issue

[acoustic belfry]

backwards?

[acoustic belfry]

shooting anim should play when chases

is a gameplay issue not a coding issue, i will think of something better later

the issue is when patrols

[rocky canyon]

u said they walkin backwards

just lookin thru for a reason

[acoustic belfry]

i mean, they walk as they intend, but when they walk, their object size is made negative, for flip them whole

the issue, now flips them whole when dont need to

[rocky canyon]

i think its just a logic problem.. not really a code issue

[acoustic belfry]

    {
        if (detectoValeria == false)
        {
            contador -= Time.deltaTime;
            if (contador <= 0)
            {
                contador = tiempoParaCambiar;
                moverDerecha = !moverDerecha;
            }
            if (moverDerecha)
            {
                mortemRb.linearVelocity = new Vector2(speed, mortemRb.linearVelocity.y);
                transform.localScale = new Vector3(1, 1, 0);
            }
            if (!moverDerecha)
            {
                mortemRb.linearVelocity = new Vector2(-speed, mortemRb.linearVelocity.y);
                transform.localScale = new Vector3(-1, 1, 0);
            }
        }
    }```

[rocky canyon]

the patrol method plays riflepartrol.. but ur mortemtropper chase also plays rifleshooting always even when too far to shoot

[acoustic belfry]

o no it always shoots

[rocky canyon]

so if u ever accidently land in Chase while far they'll still shoot

[acoustic belfry]

the far thing is for check if should chase or stay in place

[rocky canyon]

oh okay

yea for the walkin backwards thing i would guess u flip based on the player position and not its current movement

soo u get like a moon-walkin trooper

[acoustic belfry]

yep

[rocky canyon]

u could flip by velocity

[acoustic belfry]

velocity?

[rocky canyon]

void flipByVelocity(Rigidbody2D rb)
{
    if (rb.velocity.x > 0.01f)
        transform.localScale = new Vector3(1, 1, 1);
    else if (rb.velocity.x < -0.01f)
        transform.localScale = new Vector3(-1, 1, 1);
}```

ya the direction ur enemy is moving basically

if X velocity is positive ur moving ->

if X velocity is negative ur moving <-

[acoustic belfry]

o h

[rocky canyon]

also debug ur states while working

it'll help ... maybe even a little overlay TextMeshPro

Debug.Log(currentState); textMeshPro.text = currentState.ToString();

[acoustic belfry]

I discovered the issue, wasn't coding, i forgot that i tried to use the animator for the scripts, instead of just put the play

now i check the transitions made this issue

well, thanks anyways, atleast now i can debug my states, and i know how to flip better :3

[rocky canyon]

yup

[acoustic belfry]

you meant linearVelocity, right?

[rocky canyon]

yea same thing

if ur using unity6+ its linearVel

if its older its vel

[gleaming haven]

using UnityEngine;

public class Gravity : MonoBehaviour
{
    [SerializeField] private CharacterController controller;    //reference to CharacterController component of FPS_Controller
    [SerializeField] private float gravity = -9.81f;            //gravity in m/s²
    public float downwardVelocity = 0f;                         //downward velocity gradually increases during free fall

    // Update is called once per frame
    void Update()
    {
        //reset downwardVelocity if player is on the ground 
        if(controller.isGrounded && downwardVelocity < 0){
            downwardVelocity = 0f;
        } else {
            //increase downward velocity using the gravity value
            downwardVelocity = downwardVelocity + gravity * Time.deltaTime;
        }

        //create vector from downward velocity along Y axis
        Vector3 gravityVector = new Vector3(0f, downwardVelocity, 0f);

        //apply gravity vector to the player
        controller.Move(gravityVector * Time.deltaTime);
    }
}

does anybody know a quick fix to why the downwardVelocity still increases while standing on the ground? it should only increase when the player is mid air, but I cant get it to work

[waxen adder]

The first thing I can say is double check your logic surrounding controller.isGrounded. Could add some debug.logs to see what state it's in as well

[gleaming haven]

i tried that, it seems to only spit out debug logs when i move the character, so it appears to not update when the character is standing still

[waxen adder]

Where'd you put the logs?

[gleaming haven]

into the first "if"

[waxen adder]

Put it out in update land

So like:

void Update()
{
Debug.Log("Is grounded value: " + controller.isGrounded);
...stuff
}

[gleaming haven]

oh yeah wait

it says false even if im on the ground, thats odd

maybe it's wrong to check isGrounded on an empty object

because my controller is an emptyobject with the charactercontroller component

[waxen adder]

Personally I haven't messed with physics/jumping logic, so I can't say what's the best there, but yeah, from what it seems there's at least something wrong with the logic around isGrounded

[gleaming haven]

ill look into it, ty

[wintry quarry]

CharacterController.isGrounded is notoriously bad

almost everyone uses their own separate grounded check implementation

usualy with raycast or capsulecast

[magic knoll]

Hey guys, I wasn't really regarding on my console during my last modifications, and I have those errors that spawns on my game start.
I think i checked all my prefab serialize objects, and everything seems clear.
Do you have any suggestion to help localize this kind of errors ?

I tried to remove almost all prefab ref of my scene, but still occurs

And it doesn't prevent the game to run

[rocky canyon]

looks like Editor issues.. and not anything you've done..

u can try restarting the project/ editor/ perhaps the PC

can also try deleting the Library folder w/ the project closed and re-open it to allow Unity to rebuild its Library.. (sometimes that sorts out unknown errors)

[magic knoll]

Damn

It's been 30mn i'm looking every single object of my game xD

[rocky canyon]

lol oof

check out the errors

anything UnityEditor. blabla is editor stuff

[naive pawn]

.DS_Store if you or someone you're working with is on mac

[rocky canyon]

if u dont have editor scripts.. then its most likely a unity thing and not a you thing

[magic knoll]

Yeah, I saw that but i don't know, i thought i made some really terrible script that was breaking something ^^

[rocky canyon]

could also just be a bugged out window..

reset the Layout as well

[magic knoll]

Just restarted the editor and it fixed 😄

[rocky canyon]

should jot that down on a notepad..

[harsh haven]

Hi, need some basic physics help:

Basically, making a simple basketball game.
I am implementing jumping and picking up the ball, and to do jumping i had to use rigidbody and allow the character to be affected by forces. Both jumping and ball pickup work fine, but not together, as

The ball while dribbling makes contact with the player, and so pushes the player in weird directions and messes up movement. I fixed this by excluding the ball layer from the player's rigidbody. However, if I exclude this layer, the player's ontrigger component no longer recognizes the ball when the two make contact and the ball needs to be picked up after shooting. How can I allow the player and ball to register collisions (so ball pickup can happen), but the physics of the two don't affect eachother when in contact?

[rocky canyon]

well sounds like ur onto a solution already

u can change layers, and rigidbody settings @ runtime..

settings that allow pickup -> then once picked up -> change settings that allow dribbling

[harsh haven]

Hmm so like

When ball is dribbling, exclude the ball layer from rigidbody

When the ball needs to be picked up, include it

ok yea true lol i just didn't know if this was the best solution, cause like

since im a beginner i dont wanna bring up bad habits or work around solutions in weird ways

thought there was maybe a more direct way to fix it universally

[rocky canyon]

there probably is.. but it'd be more convoluted and more complex than using the settings/ layers/ and tickboxes they already have

or u could have a pickup ball thats different than ur play ball

[harsh haven]

oh yea thats an interesting idea too

[rocky canyon]

thats how most games actually do pickup objects in general

theres a pickup thats basically a trigger
when u pick it up.. u despawn (destroy) /disable that object
and spawn in the real object that pickup represent

[lapis parrot]

ok so my script for picking stuff up kinda works? it only works sometimes when i spam "e" https://paste.mod.gg/bvqcqbnsasop/0 please help

[rocky canyon]

dont poll for inputs in trigger function

that only runs X amount of times / second.. UNLESS u hit it EXACTLY when that function gets called its pointless

instead use a boolean or something to toggle when and when not to poll for input

[lapis parrot]

oh.

wait

i kinda understand what you mean

[rocky canyon]

    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space))
        {
            if (isInTrigger)
            {
                Debug.Log("Space key was pressed and we're in the trigger");
            }
            else
            {
                Debug.Log("Space key was pressed but we're not in the trigger");
            }
        }
    }

    void OnTriggerEnter(Collider other)
    {
        isInTrigger = true;
    }

    void OnTriggerExit(Collider other)
    {
        isInTrigger = false;
    }```

does this clear things up?

void Update()
{
    if (Input.GetKeyDown(KeyCode.Space) && isInTrigger)
        Debug.Log("Space pressed & in trigger");
}``` or combine the two conditions...

point being that Update() runs every frame... so when u press the input it gets grabbed.. regardless

and then u check also if ur in the trigger (if ur not it gets ignored) and let the code run

this doesnt mean anything in ur code...
its set to true.. and it'll always be true b/c u dont change it anywhere..

isInRange can be exactly what i used up above ^

if u enter trigger set it to true..
when exit trigger set it to false..

then do ur input like regularly in Update().. and check that boolean

[boreal night]

preciated

[lapis parrot]

Oh my God you're a genius

[rocky canyon]

nah, i wouldn't say all that..

but its a common way to do inputs 'n triggers

Hi, I'm brand new to unity and coding. I'm just starting the book that advertised this group.

I'm literally a complete noob, but I've realised that visual studio for mac used in the book isn't supported anymore so I have to use visual studio code. I feel quite dumb saying this but I'm finding it quite difficult to follow along with the instructions in the book because visual studio code doesn't have the start method I'm told to put the debug.logs inside of.

Does anyone have any advice? Should I just copy the diagram in the book into visual studio code?

[polar acorn]

configure ur IDE ^

it surely does

[polar acorn]

It'll be in the default script template no matter what IDE you're using

[spiral night]

Thank you, I will try configure this.

[rocky canyon]

you'll also want a few extensions to help out.. the c# devkit.. unity/ unity snippets

[spiral night]

Thank you very much! Have you completed the book at this stage?

[rocky canyon]

ive been using unity for 5 years now

[lapis parrot]

but now it's saying that the bool does not exist in the current context

[rocky canyon]

well, did you declare a boolean to use?

[polar acorn]

Which bool?

[rocky canyon]

they dont just exist... u have to declare a boolean

and use that to set true and false in ur trigger functions

[spiral night]

Wow that's sick. Do you have any released games or are you working on any at the moment

[rocky canyon]

    public class TriggerCheck : MonoBehaviour
    {
        public KeyCode interactKey = KeyCode.Space;

        private bool isInTrigger;

        void Update()
        { ....```
i didn't post the full script.. (just an example)

[rocky canyon]

im more of a hobbyist... i make art assets [3d models n such] mostly

[lapis parrot]

oh i see i see

neuron activation here

[rocky canyon]

gotta think outside that box a bit

[ivory bobcat]

When you create a new mono behavior script from the Unity Editor, the script will be populated with the default necessities (basic imports, inherits mono behavior, have a Start and Update method etc)

[spiral night]

oh okay I thought I was following the book but I must have made a mistake. I will go back and redo this properly. thank you very much

[rocky canyon]

like-so

pro-tip rename the script during creation and the class name will match in the script..
avoiding problems like forgetting to rename the class

[spiral night]

oh yes I got that in my notes 😂 I think my problem was I went into scripting and chose empty c# script instead of monobehaviour

[lapis parrot]

this kinda works, but since bools are constantly false it just says that it's false all the time, basically saying it's not in range

[rocky canyon]

then ur trigger must not be setting it to "true"

[polar acorn]

Where do you set it to true

[lapis parrot]

 private void OnTriggerEnter2D(Collider2D other) //Player entering item range
    {
        bool isInRange = true;
    }

[ivory bobcat]

Are you also setting it to false anywhere? You declared a local variable there, in that method, and assigned it the value true.

[polar acorn]

You're setting a local variable, then doing nothing with it

When the function ends, that variable ceases to exist

[lapis parrot]

oh shoot

no private

[rocky canyon]

   void OnTriggerEnter(Collider other)
    {
        Debug.Log($"We collided with: {other.name}");

        if (other.CompareTag("Player"))
        {
            Debug.Log("We tested and collided with the player!");
            isInTrigger = true;
        }
    }```

the boolean needs to be declared at the top

outside the functions

that way the entire class can use it

^ and if u put [SerializeField] in front of it.. it'll expose it in the inspector.. that way u can physically watch it change during testing

[lapis parrot]

wait so is this not outside the functions https://paste.mod.gg/jwpwmdxursyz/0

[lapis parrot]

seriously? dang

[rocky canyon]

well ya but ur not assigning the bool at the top

ur creating a NEW one... in the triggers..

dont do that

[polar acorn]

You have created one outside the function, then you're making new ones inside of the functions

Don't declare new variables.

Assign the one you already have

[rocky canyon]

just set the isInRange boolean you already have

[ivory bobcat]

You'd only usually see the type when declaring a new variable. You'd just use the variable name when wanting to access a variable.

[rocky canyon]

public class PickUpScript : MonoBehaviour
{
    public GameObject StartSwordPickup;
    public GameObject StartSword;

    public KeyCode interactKey = KeyCode.E;

    private bool isInRange;

    void Update()
    {
        if (Input.GetKeyDown(interactKey))
        {
            if (isInRange)
            {
                Debug.Log("Picked Up!");
                StartSwordPickup.SetActive(false);
                StartSword.SetActive(true);
            }
            else
            {
                Debug.Log("You're not in range!");
            }
        }
    }

    void OnTriggerEnter2D(Collider2D other)
    {
        isInRange = true; // Correct: modifying the class field
    }

    void OnTriggerExit2D(Collider2D other)
    {
        isInRange = false; // Correct: modifying the class field
    }
}``` this is what u *should* be doing..

in this situation ^ ur declaring (1) boolean to use within the ENTIRE class

its the same one u set in the trigger functions.. and the same one u check in ur update conditionals

anywho.. that should set you up for success.. my freebies have been exhausted for today 😈

[lapis parrot]

oh my God it's because i kept on putting "bool" behind them

[teal viper]

It's called variable declaration. You're basically saying "there's gonna be a new variable with this name here"

[polar acorn]

Yes, that creates a variable. You were creating a new one inside the function.

[ivory bobcat]

Whereas without the type, you're saying that you've got a variable already by a particular name and are wanting to do something with it.

[rocky canyon]

    // this bool belongs to the entire class
    bool thisClasssBool = false;

    void MyFunction()
    {
        // this bool only belongs to MyFunction
        bool thisFunctionsBool = true;

        thisClasssBool = thisFunctionsBool;
    }```

so anywhere outside of MyFunction() thisFunctionsBool can not be accessed

you'll sometimes want to have variables that the function may need to execute w/e it is that its trying to do.. but those variables aren't needed anywhere else..

like for example if u had a function that did alot of math and spits out a number
you may need to use variables to temporarily store numbers to calculate with later on in the funciton
but those variables aren't needed elsewhere

[outer coral]

kind of odd question but:

If i have a virtual method that I am overriding and in the subclass implementation I use the base.MyFunction(); call is there a way i can return out of both from inside the base method? For example I want to check a condition on every object that uses that class but I dont want to rewrite the check for them all I just want it to short circuit but since I have other implementation after the base call it would still run. Any way to do this without copy pasting

[red rover]

Just a sanity check, continue will continue in the closest loop, right? The z loop in this case?

for (int x = -4; x <= 3; x++)
{
    for (int y = -4; y <= 3; y++)
    {
        for (int z = -4; z <= 3; z++)
        {
            if (l > 0 && CheckGapRange(x, y, z)) { continue; }
        }
    }
}```

Hey,
I tried to optimize my GenerateOtherTiles() method to use nested loops instead of alot of if statements but for some reason it broke my game, reavealing all the tiles in the grid when I click on a tile and also not displaying the numbers on the the tiles when I click on a tile. Does anyone know why please ?

Here's the optimized code that I wrote for that method:

private void GenerateOtherTiles()
{
  for (var i = 0; i < GRID_WIDTH; i++) {
    for (var j = 0; j < GRID_HEIGHT; j++) {
      if (tiles[i,j].Value == -1) continue; // If it's a "Mine" tile, skip all the code below
      
      var minesAmount = 0;

      // Loop on every neighbour around the current "Tile"
      for (var h = -1; h <= 1; h++) {
          for (var v = -1; v <= 1; v++) {
              if (h == 0 && v == 0) continue; // This is ourselves, not a neighbour, so "continue"
              if (!IsInGrid(h, v)) continue;  // The coordinates "h,v" are outside the grid, so "continue"
              if (tiles[h, v].Value != -1) continue; // If the neighbour isn't a mine, "continue"

              minesAmount++; // It's a mine, so add 1 to "minesAmount"
          }
      }
      tiles[i, j].Value = minesAmount;
    }
  }
}

Here's the previous code that I backed up before doing that change : https://paste.mod.gg/tlzuqzajpsnu/0
All the rest of the code is the same in both 🙂

I think I know why 🤔 I forgot to add h and v to i and j 😬

Yup, that's the issue, thanks 👍 🙂

[heady herald]

hey yall, can anyone help me figure out how to make this code not freeze up unity? I think im doing a memory leak or underestimating how expensive this code is, but its freezing unity indefinitely and i do not want it do that

using System.Linq;
using TMPro;
using UnityEngine;

public class ClockScript : MonoBehaviour
{
    public TMP_Text ClockText;
    public int TicksTilNextUpdate = 150;
    public static OurUniversalClasses.OurDateFormat CurrentDateTime;

    private void Awake()
    {
        CurrentDateTime = new OurUniversalClasses.OurDateFormat();        
    }
    void Start()
    {
        ClockText = GetComponent<TextMeshProUGUI>();
    }
    void FixedUpdate()
    {
        
        if ( ((float)TicksTilNextUpdate)/25f % 1 == 0 && ClockText.text.ToList().Contains(":".ToCharArray()[0]))
        {
            //Debug.Log("yep");
            ClockText.text.Replace(":", " ");
        }
        else if(((float)TicksTilNextUpdate) / 25f % 1 == 0)
        {
            ClockText.text.Replace(" ", ":");
        }

        TicksTilNextUpdate--;
        if( TicksTilNextUpdate < 0 )
        {
            
            CurrentDateTime.AddSeconds(60);

        }
    }

tysm

what this is supposed to do is make a clock do that thing where the ":" blinks in and out

ideally it would do that every half second

[sour fulcrum]

Can't see anything in this that would freeze unity 🤔

[heady herald]

hm weird

[sour fulcrum]

by the way, string has a contains function directly

[heady herald]

im pretty sure its this script causing it but maybe i should do a more thorough check

[heady herald]

oh...

[sour fulcrum]

if (text.Contains(':'))

[heady herald]

probably should have checked before doing that jank 😭

yeah it runs fine until i turn on the script

then immediately starts freezing

fixed update gets called 50 times a second by default right?

it takes a bit to start crashing so it feel memory leak to me but also idk what could even be leaking

these are all local varriables so they should get automatically dissmissed

[sour fulcrum]

Also hope you don't mind the feedback, but you don't need to do that check twice, you could just do

        if (((float)TicksTilNextUpdate) / 25f % 1 == 0)
        {
            if (ClockText.text.Contains(':')
                ClockText.text.Replace(":", " ");
            else
                ClockText.text.Replace(" ", ":");
        }

or

        if (((float)TicksTilNextUpdate) / 25f % 1 == 0)
        {
            (string,string) swap = ClockText.text.Contains(':') ? (":"," ") : (" ", ":");
            ClockText.text.Replace(swap.Item1, swap.Item2);
        }

[heady herald]

yeah fair

i was trying to avoid nesting but that 2nd option is much cleaner

[sour fulcrum]

might be worth commenting out specific parts of the code and seeing if you can pinpoint the issue?

[heady herald]

hm maybe

[sour fulcrum]

tbh could also just have two textmeshprougui's where one has it and the other doesnt

and flip their activity

[heady herald]

yeah maybe thats easier

the ticking works fine

when i comment out the if

which was kinda expected

nvm i lied to you

the editor frozen when i was typing

uh oh

should i just not be calling fixed update

[sour fulcrum]

no that should be very harmless

usually full freezing stems from either while loops or recursion

[heady herald]

yeah this is weird

commenting out the incrementing of TicksTilNextUpdate seems to work to stop crashes

but also

i really need that...

oh wait intresting

it only crashes when ticks hits 0

i think its a problem with my datetime function

yeah its just the datetime function which is broken apparently

okay yep its just sleep deprived function writing

ty for your help!

[sour fulcrum]

Glad you got it working 😄

[lusty viper]

Anyone know how to find the acceleration for an object given its mass and the strength of a force being applied to it? I tried doing just acceleration = mass / force, but I guess I'm not sure what units are being used because the resulting number didn't seem to line up at all with the actual change in magnitude of velocity over time

[heady herald]

what are you using this for?

dependin on your use case, you could just get acceleration by comparing velocity at two different times

calculate it as a change in veloctiry

unless you need to predict aceleration, its imo best to just compare two velocities and times

[lusty viper]

Yeah, that's what google says a lot haha. I'm using it to try to know the potential acceleration possible given you apply a certain force. Basically I've got a little spaceship guy and I want to have it accelerate towards a target, and at every tick, figure out whether it should be accelerating forwards or decelerating such that it reaches the target with velocity 0

[heady herald]

how set are you on using physics over translation?

might as well check

[eternal needle]

the addForce formulas arent anything special. you should get the same result as addForce with velocity += force * fixedDeltaTime / mass
assuming no friction or other interferences

[lusty viper]

I'd definitely prefer it, hoping for a more physics based game w/ no friction and stuff

[eternal needle]

you also cant compare the results right away as addForce actually changes the velocity duing the physics loop, if you were doing that

[heady herald]

i see

[lusty viper]

Ahhh maybe the fixedDeltaTime part is what I was missing, I was calculating it as just force / mass

I'll try that out, thanks!

[eternal needle]

not sure if it was a typo but initially you wrote mass / force

[lusty viper]

Oh it was, mb

[coarse stag]

Can someone link me a good C# course, that shows every step piece by piece

[cyan crescent]

Hi, just started learning to code using c# in Unity to create a game. I'm still having a hard time understanding codes like functions and symbols (like the difference between (), {}, =, . and others) using visual studio. Are there any good tutorials to familiarize myself to basic code functions?
Currently using this tutorial as my first guide, very helpful but wanna know if there is anything more basic than this one. Thanks

https://youtu.be/XtQMytORBmM

[sour fulcrum]

To be 100% it's something you def. learn with abit of time but maybe some interactive tutorials (eg. codeacadamy, learncs etc.) might help abit?

the usage of those characters is very consistent so it's easy to pick up on when and where you'd use it based on the context

[cyan crescent]

Thank you for the recommendations, I was really excited when I was able to move an object using a code, then got frustrated as soon as errors occur. Still excited as this is a new realm that's a bit far from what I'm used to.

[visual linden]

If you're new to programming entirely I'd recommend checking out something like Harvard's CS50: Introduction to Computer Science (https://youtu.be/LfaMVlDaQ24)
Learning programming through Unity can be a bit of a painstaking process since you're essentially learning two (three?) domains at once. Watching a few of the CS50 lectures and maybe a brief C# tutorial would probably get you writing code confidently much quicker.

[sour fulcrum]

Though worth mentioning this absolutely is not for everybody

[young niche]

hey im trying to make an elevator in my game, however i use a character controller component, and when im in the elevator my character is like boucing when it goes down. Im guessing this is a gravity issue, but im not sure how to fix it since i dont want to use a rigidbody. Somebody know any easy solutions to this?

[naive pawn]

sounds like your elevator is going faster than gravity?

[young niche]

yeah, i think so, but i slowed it down a bunch so now it goes really slow, but i still bounce. Is there a way to like "glue" me to the floor of the elevator?

[grizzled crag]

what do you mean by bouncing

[young niche]

or right now i calculated that my elevator is going 1.5 units per second, while gravity is 9.81 units per second. So gravity sohuld be able to pull me down, but maybe since the elvator is a "steady" constant movement downward. While gravity accelerates velocity from 0 upward. Therefore it will bounce, however im not sure how to fix it

[teal viper]

The simplest solution is to parent your character to the elevator and disable physics(make the rb kinematic) during that time.

[grizzled crag]

I think this is your best bet

minus the rb of course

since you're using character controller

[young niche]

im not using a rigidbody, since i have my character controller

[teal viper]

Disable the character controller then.

[young niche]

yeah i tried to parent but it didnt really help

maybe, but i would like my character to still move in the future if im standing on objects that animate downward

[grizzled crag]

mmmm okay what if

make a script that forces the character to copy the y level of the elevator + an offset

and turn off the character controller's gravity

this should still allow you to move on the xz plane

while following the elevator's y position

[teal viper]

Then you'll need to sync your CC update with the object that it stands on.

[sharp bloom]

Just keep coding. They will become muscle memory.
My favourite C# resource is https://www.geeksforgeeks.org/c-sharp/csharp-programming-language/ , nice clean examples and explanations for all the basic stuff

[sharp bloom]

What's the best approach of implementing "generic" animations like reload, take aim, shoot across multiple types of weapon?

AnimatorOverrideController? I don't quite get how to use it.

[static breach]

uiCanvas = canvasObj.AddComponent<Canvas>();
why does my game, even when i have this in my code always creates my generated ui elements inside an already existing canvas? i want a new canvas to be created

oh i might found the issue

        if (uiCanvas == null)
        {
            Debug.Log($"Creating new Canvas for client {NetworkManager.Singleton.LocalClientId}");
            GameObject canvasObj = new GameObject($"MinimapCanvas_Client_{NetworkManager.Singleton.LocalClientId}");
            uiCanvas = canvasObj.AddComponent<Canvas>();
            uiCanvas.renderMode = RenderMode.ScreenSpaceOverlay;
            canvasObj.AddComponent<CanvasScaler>();
            canvasObj.AddComponent<GraphicRaycaster>();
        }
        else
        {
            Debug.Log($"Using existing Canvas for client {NetworkManager.Singleton.LocalClientId}");
        }
        ```
how do i tell him what canvas to use?

[naive pawn]

perhaps ask in #🏃┃animation

[queen adder]

I have a problem that when I added a code to make my character dash It stopped moving left and right
here's the script:
https://gist.github.com/bielo1656/02920ebd582adf83941b6da1f49b8f04
I tried to move the "body.linearVelocity = new Vector2(horizontalInput* speed, body.linearVelocity.y);" line to a FixedUpdate method but it didnt fix it
Also the player settings in the editor

[static breach]

fixed my problem

[naive pawn]

you set isDashing to true from the start

[queen adder]

OOOH MY GOD

I hate when I search for hours for an error just for me that I've done something stupid

[naive pawn]

sounds like you should learn debugging then

just putting Debug.Logs in the right place to see what's going on

[queen adder]

Im a beginner and I wonder; what is debugging?
Like yea searching for bugs and errors but it of course is something other than smashing my head through wall with internet

[knotty night]

Debugging is really just you asking your computer, "wth is wrong here?" When your code isn’t working

its about

Figuring out what’s messed up
Understanding why it's happening
Fixing it so it actually works

Sometimes it’s just a stupid typo, like forgetting the semi colon (;), and other times it’s a tricky logic issue. just be patient, and ready to do some Googling, theres nothing wrong about it\

[burnt vapor]

I suggest you read about debugging your code using the top three links listed here: https://unity.huh.how/debugging
The other points are less relevant, but very useful nonetheless.

We can't explain debugging any better than those pages do.

[knotty night]

is this page always been here? or is it new?

[burnt vapor]

Been here for a long time

[knotty night]

oh, this is the first time i opened the page

[burnt vapor]

It is referenced very often

[knotty night]

i see, i guess i have a documentation now

[sharp bloom]

Looked into factory pattern, this script does basically that you suggested.

public class ProjectileFactory
{
    public GameObject RealizeProjectile(SO_ProjectileConfig config)
    {
        if (config.itemPrefab == null)
        {
            Debug.Log("Projectile has no prefab.");
            return null;
        }

        GameObject newObject = config.itemPrefab;
        GameObject realObject = Object.Instantiate(newObject);
        realObject.GetComponent<IItem>().Initialize(config);
        return realObject;
    }
}

Now I don't have to make both the prefab and the scriptable object manually, just need to have the generic projectile script on the prefab. This works for me 👍

hey yall, im running into some problems where InputField.isFocused always returns false

I was under the impression that it would be true when the InputField is being edited and false when its not

but that doesn't seem to be happening

    public void Update()
    {
        bool anyEnter = Input.GetKeyDown(KeyCode.KeypadEnter) || Input.GetKeyDown(KeyCode.Return);
        if (anyEnter && inputField.isFocused == true)
        {
            Debug.Log("hit");
            Lines.Add("");
            inputField.text = "";
        }

        //stupidly expensive. its ok
        Lines[^1] = "> " + inputField.text.Replace("\u2588", "");
        ReloadText();
    }

huh

my code for referance

[slender nymph]

why manually poll for enter+focus when you can just subscribe to its onSubmit event instead?

[heady herald]

oh is that what that does?

ill check that out, ty

[gaunt solstice]

Hello, I need help with a 2d platformer I'm making. I want to have a mechanic similar to mario or sonic where the player can jump on an enemy, and when they do they bounce off the enemy a little. I was able to get the bounce working fine but I want to make it so the height of their bounce is dependant on how fast they're falling and that doesn't seem to be working. Here's the code I have so far

    {
        float fallingSpeed = Mathf.Abs(rb.velocity.y);
        float bounceForce = fallingSpeed * bounceMulti;

        rb.velocity = new Vector2(rb.velocity.x, bounceForce);
    }```

[rich adder]

log the fallingSpeed when it gets called , most likely you need to track vertical velocity in fixed update, before collision happens

[gaunt solstice]

so is it cause when the collision happens the falling speed decreases?

[rich adder]

if you collide something you could be grabbing the velocity when it has collided so the velocity is not what it used to be before colliding

[gaunt solstice]

so how do i log it before the collision happens

[delicate zinc]

is there any way to make ontriggerenter detect a boxcollider of a child instead of just every boxcollider on the object

[rich adder]

track it in a separate variable as I mentioned earlier, in fixed update

[delicate zinc]

i have it set up where the player hitbox is a seperate object thats animated when the player attacks, but since the player spins when they attack, the player hitbox sometimes clips into the enemy and activates a hit anyway

[rich adder]

probably using Layers / Collider filtering

[delicate zinc]

is there any way to get the hitbox specifically from this

[rich adder]

what like other ?

[delicate zinc]

other is checking for the enemy so idk how to check for my hitbox

[rich adder]

you would need a reference to it but don't think that will do what you want

you want that to ignore something why not change the Layers filtering or am I not understanding what ur issue was

[delicate zinc]

wait a sec lemme try find a better way to explain it lol

the enemy has a script that checks for playerhitbox when it takes damage (screenshot 2), and the player hitbox has that, but the script that i put on the player to apply recoil and knockback still goes off sometimes without dealing damage, since the players hitbox clips into the enemy (screenshot 3)

[rich adder]

how exactly is it making it do that though ?

[delicate zinc]

do what

[rich adder]

recoil and knockback still goes off sometimes without dealing damage, since the players hitbox clips into the enemy

[delicate zinc]

lemme get a video

at least i think the player hitbox is clipping into the enemy since idk what else would be causing it

i do it at like 0:09

[rich adder]

the red trigger is supposed to hit the enemy but doesn't knock back ?

[delicate zinc]

no its meant to hit the enemy and deal damage but in the video i somehow knockback without the red trigger hitting it

so the enemy doesnt take damage

[lusty viper]

What's causing the knockback? Is it a separate collider?

[delicate zinc]

i found a way to consistently trigger it if i run into the enemy near the end of the animation

[rich adder]

you mean this ?

[delicate zinc]

yea

[rich adder]

you have different triggers on the player ?

[delicate zinc]

its meant to be the red trigger but the player hitbox is causing it too

[delicate zinc]

nou

[rich adder]

cause that knockback only waits for Triggers

[lusty viper]

Sounds like you need the script that causes the knockback to be on a different nested gameobject with the red collider so that onTriggerEnter would only trigger for that one

[delicate zinc]

ouh oka

ill try that

[rich adder]

does the enemy have regular collider or trigger?

[lusty viper]

That's my first guess anyways, probably other solutions

[delicate zinc]

regular collider

[rich adder]

a rigidbody also ?

[delicate zinc]

yeah

[rich adder]

could be colliders going into eachother rather then knockback itself, you could try to comment out the knockback part or put a log to see if thats the one causing it

[delicate zinc]

it is the knockback tho since it causes the game to slow down and play the sound effect

[delicate zinc]

im trying this rn

[lusty viper]

I would say one gameobject per thing that colliders are supposed to do is generally a good idea but I'm not an expert idk

[delicate zinc]

omg that fixed it

tyyyy

[gentle merlin]

iam getting this errer

InvalidOperationException: Nullable object must have a value.

and its coming from var bp = best.Value; here

https://paste.mod.gg/tvwudnkmyxpe/0

and i canno't for the life of me trace it down

[naive pawn]

it's telling you where the source is

best doesn't have a value, it's being used on line 115

[gentle merlin]

ik that bp is returning as 0, but i can't find where it becomes 0

[naive pawn]

that's not what it means, no

[gentle merlin]

oo i see okay

[polar acorn]

You should probably make a struct for this and make a list of that struct instead of this tuple

[naive pawn]

also have p as Chessman instead of GameObject

[gentle merlin]

okay i made both of those changes

i placed alot of print(....) of different places i think could be causing best to stay null but still no dice
https://paste.mod.gg/pptkfdcilfay/0

not a single one goes off

[naive pawn]

then GetAllPieces is returning an empty list, or dMax is less than 1, or the time thing doesn't pass

[gentle merlin]

i just found what might the reason as u sent this

public void GetAllPieces(string playerColor)
    {

    }

[naive pawn]

(why do you have the dMax loop anyways, it doesn't do anything)

[gentle merlin]

this shit is empty

i was trying to trace each variable back to its soucre when i found this, let me fill it in and see

[gentle merlin]

idk at this point i have been gutting this code back and forth fixing some stuff before i gotta clean it all up

looking back that section of code has always beem empty, and it had been working until now so i don't think thats the error

[torn dragon]

guys am new to unity and this scene looks fine here but

[torn dragon]

i cannot see anythibng when i

switch to this

[polar acorn]

What is your camera currently looking at?

[torn dragon]

Cinemachine cam is focused on the player model

[polar acorn]

Go into 3D mode, take a look at the camera's boundaries and see what is inside it

[torn dragon]

i did something and now i cannot zoom in 😭

how much should this value be

[polar acorn]

The zoom speed? Whatever you want it to be.

Scroll wheel while moving to adjust

But from this view, select your camera and see what's in its view

[torn dragon]

am scrolling its not zooming in

[polar acorn]

Scrolling while moving changes the move speed of the camera instead of zooming.

[torn dragon]

i used middle button to look around and scrolled and now i cannot zoom in no matter how much i scroll

[naive pawn]

press F to focus

[torn dragon]

ty

[naive pawn]

you're currently either way too zoomed in or out

[torn dragon]

why is my main camera moving

the z coordinates are changing constantly

its nowhere near the main thing

player

and its going further away in z axis

[polar acorn]

Probably because you have something moving it

And yes, that does indeed seem very far away

[torn dragon]

hhow do i find out

[polar acorn]

Check your code

[torn dragon]

i don't have a code for camera though

[polar acorn]

But you have cinemachine that is presumably following something, and probably code that moves that thing

[torn dragon]

oh wait i didn't have the player on focus

this is fine ig

so this player model is supposed to move in a linear path but its not

[kindred iron]

wdym

[acoustic belfry]

what diferences, animator.play and animator.crossfade have?

for direct logic usement of animation wich one's better?

[kindred iron]

crossfade has a fade the animations play smoother

u can see the difference between them in yt ig

[torn dragon]

can i paste links here

https://www.youtube.com/watch?v=AoRBZh6HvIk&t=10s&ab_channel=GameCodeLibrary

0:45

the player model moves on x axis

she has the asset and i imported it

[kindred iron]

can u come vc?

[torn dragon]

sure i don't have a mic though

[kindred iron]

i called you

[acoustic belfry]

i just need to play pixe-art sprites in my game, wich one is smarter in theory?

[naive pawn]

@kindred iron @torn dragon we'd rather you discuss here, fyi
going to private chats defeats the purpose of having a community server

[naive pawn]

crossfade wouldn't make a difference in changing sprites, since they're discrete

just use Play for simplicity

fyi that kind of question would be better suited for #🏃┃animation

[torn dragon]

okioki

[kindred iron]

no it doesnt actually. In this Chat i can see who needs help

and thats the purpose

and

we dont discuse in private

but instead he streams in private and he shows me the problem

its better like that

[acoustic belfry]

oh, ok, well, thanks :3

[naive pawn]

that is indeed discussing in private

[naive pawn]

the purpose of a community server is to have multiple people available to help any given person - multiple people able to see potential issues, perhaps point out things that will be an issue in the future as well

with private help, DMs, calls or streams, that's completely lost - and if that one helper happens to become unavailable or is unable to help, it then becomes the asker's problem to ask everything all over again for someone else

[kindred iron]

yeah but its easier to handle it in vc

and i increase my english too when i speak

[naive pawn]

additionally, with a public discussion, other people in the chat can benefit from the conversation as well, and other members can check answers, and moderators can do their job

[kindred iron]

so i prefer talking tbh

[naive pawn]

ok, live with the conscience that you're harming other people by taking the "easy" option i guess

idk why you'd say it's easier to handle in VC either tbh, i find it wayyyy easier when stuff is laid out in text or images
video and especially audio is a pain to check through when trying to find issues

being able to communicate issues in text is a skill that definitely needs way more practice than talking

these things are standardized for a reason

[gentle merlin]

is there a reason this code is nto stopping for friedly pieces? (gave up on the other bot so iam using my second bot i had made but this pesky issue i the only thing it as rn)

public void LineMovePlate(int xIncrement, int yIncrement)
    {
        Game sc = controller.GetComponent<Game>();

        int x = xBoard + xIncrement;
        int y = yBoard + yIncrement;

        while (sc.PositionOnBoard(x, y))
        {
            GameObject piece = sc.GetPosition(x, y);

            if (piece == null)
            {
                MovePlateSpawn(x, y);
            }
            else
            {
                if (piece.GetComponent<Chessman>().player != player)
                {
                    MovePlateAttackSpawn(x, y);
                }
                // Stop for either friendly or enemy piece
                break;
            }

            x += xIncrement;
            y += yIncrement;
        }
    }

[kindred iron]

thank u for the advice

[gentle merlin]

I have one piece thats like the queen in chess, and it uses this method to move. So far tho its first move in the game its to jump over its friends and eat my pawn

[naive pawn]

try debugging some stuff, check if piece is what you expect it to be in each given x, y position

also, like before, you should have piece as a Chessman instead of a GameObject so you don't need to do GetComponent on it
might also apply to controller if that happens to also be a GameObject

[acoustic belfry]

what is hashing?

Someone knows a way to check the quality of a script? Or how re-organize it?

Cuz im trying to enchance my player's script but i dont know how

[naive pawn]

"quality" is a quite subjective and, well, qualitative

[pallid nymph]

You can always ask ChatGPT 😅

I'm sorry, I couldn't help it. You probably shouldn't do that.

[naive pawn]

the main things i'd look for at a beginner level would probably be

• repeated code or things that could be generalized with math
• numbered variables
• indirection/magic strings/magic numbers

[naive pawn]

last time someone tried it had like a 50% accuracy 😆

[pallid nymph]

I should try it as well, I'm sure it would be fun 😄

[naive pawn]

i take it back, it was actually worse lmao
mostly moot points and a few actually harmful recommendations

[brave robin]

"Hi, I can totally help you with your Unity code! First off, it is wasteful to cache your GetComponent calls in Start, you should instead call GetComponent in Update..." - ChatGPT

[acoustic belfry]

thats something i wanted to ask but i was scared

for check Script's readability, what AI is better?

... sorry

[polar acorn]

It's not really a quantifiable thing

[acoustic belfry]

readable, and easy to understand

atleast readable

im trying to modify and check my player's script, yet...i dont even understand what i did

or i should just follow the joke fused with advise
"If it works, leave it alone"

[polar acorn]

You just kind of decide how much you hate yourself looking at the code. If it's a little bit, you're probably fine. If it's a lot, you should fix it. If it's not at all, then you probably don't yet know why you should hate it and should probably take another look

[acoustic belfry]

i hate myself

[polar acorn]

Right, but like the normal programmer amount

or more so

[acoustic belfry]

with or without the code

but in this case

with the code

[acoustic belfry]

dang it, i wanted to make the pun first, xd

but now returning to seriousness, well

i dont...understand it, and i feel like i should do it

[acoustic belfry]

more

like im not made for this yet i want to

Hiccup but for coding

[gentle merlin]

i checked and yeah all the pieces are where they are supposed to be, it says it breaks out of the loop when it encounters a friedly piece but then dosen't? its checks board positions not in the assigned increments as well, and then jumps to a position which it previously indicated there was a friedly piece in that line and that it had broken out of the loop.

 public void LineMovePlate(int xIncrement, int yIncrement)
    {
        Game sc = controller.GetComponent<Game>();

        int x = xBoard + xIncrement;
        int y = yBoard + yIncrement;

        while (sc.PositionOnBoard(x, y))
        {
            GameObject piece = sc.GetPosition(x, y);
            print($"Checking position ({x},{y}): piece = {(piece == null ? "null" : piece.name)}");

            if (piece == null)
            {
                MovePlateSpawn(x, y);
                print($"MovePlateSpawn at position: ({x}, {y})");

            }
            else
            {
                if (piece.GetComponent<Chessman>().player != player)
                {

                else

                Debug.Log("Breaking the while loop now.");
                break;
            }

            x += xIncrement;
            y += yIncrement;
        }
    }

its not checking the board like a queen, its literly just scanning the whole board

[naive pawn]

are you calling LineMovePlate multiple times? the logs might be confusing if you are

[gentle merlin]

its supposed to be once per direction but it seems like it calls it twice per spot with a friedly piece and 20 times per empty/enemy

[split plover]

Quick question, if a coroutine is in an if statement will it still fully go through the full coroutine if the if statement isn't active after the coroutine starts

[naive pawn]

the coroutine was never in the if statement
the coroutine call was in the if statement
once it's called, the if statement becomes irrelevant, it's not gonna be checked again automatically from inside the coroutine

[split plover]

i probably should've made the code first before asking cause i completely forgot you use startcoroutine in an if statement and you dont actually put a coroutine in the if statement

[naive pawn]

check out why that's happening, make it only call once so you can better debug a single call

[split plover]

Did i make this array wrong? I dont know why this is happening cause it was just working not too long ago
int[] DamageArray = [20, 40, 20, 60, 100];

[polar acorn]

You can't use that syntax in Unity's version of C#

You need the new int[] {} syntax

[split plover]

Question on this, why would i need to put new?

[polar acorn]

Because that's how you create a new array in the version of C# Unity uses

[split plover]

What do you mean by create a new array?

im just gonna look it up cause it gives me a warning if i use new but if i dont use new it doesn't give me a warning

[polar acorn]

I mean... create a new array

[split plover]

but i wanna use the array i made not make a new array

[polar acorn]

What array you made

where did you make it

[ivory bobcat]

The array you made was a new array.

[split plover]

above start

[ivory bobcat]

Collection expression isn't available in C# 9.0

[polar acorn]

The line you showed? The one that doesn't work? I told you what to do instead of that

[split plover]

well now that i've changed the [] to {} its working but it gives me a warning if i try to put new instead of just leaving it

[ivory bobcat]

Reminder that Digi provided the syntax not what to copy and paste into your script.

[slender nymph]

what is the warning

[polar acorn]

What warning

[naive pawn]

did you put new at the start of the line...?

[split plover]

it says it ddoes not hide an accessible member and says the new keyword isn't required but digiholic said that i have to use new so im confused

[naive pawn]

yeah you didn't put it in the right place

[slender nymph]

you put the new on the wrong part

[polar acorn]

What does your line of code look like

[naive pawn]

- new int[] x = [...];
+ int[] x = new int[] {...};

[split plover]

its exactly like how you put it in syntax, new int[] DamageArray = {}

[polar acorn]

That's not what I put

[split plover]

but up here it is

[slender nymph]

not quite

[polar acorn]

Notice how I put new int[] {} and not new int[] DamageArray = {}

[split plover]

well it says i don't need the new keyword so im just not gonna use it

seems like its working fine without it

[polar acorn]

Because that's not how you declare a list

[naive pawn]

buddy i think you're conflating a few things

[polar acorn]

and is not what I said to use

I told you what to use instead of the expression syntax that isn't available in Unity's C# version

at no point did I say to change how you declared the variable.

Just what you assign it to

Notice how what I said to do does not have an = in it

because everything before your = was correct and shouldn't have changed

[split plover]

Im confused though

[slender nymph]

#💻┃code-beginner message

[split plover]

yeah no

i understand that

but im confused on why i'm being told that i wasn't supposed to do what i was told to do

[polar acorn]

No one told you to do what you did

[split plover]

im feeling like im getting conflicted answeers

[polar acorn]

You did something else that was not what I said to do

[split plover]

You said this was the right syntax but never explained to me in any way that i did not need to add new to it

[slender nymph]

you misread what was told to you, you were not told to do something you shouldn't be doing

[polar acorn]

It is the right syntax. It's the thing you should set your variable to

[naive pawn]

there are 2 ways to instantiate an array in c#
a collection expression, [...]
an instantiation expression, new T[] { ... }, which has a shorthand, { ... }

the former is not available in the version of c# that unity uses

[polar acorn]

It's the thing that goes after the =

[slender nymph]

you do still need to use the new keyword. you're still misunderstanding even the thing you said you understood

[naive pawn]

you do have to add new in the full form - you added it in the wrong place
in the specific usage you have, new int[] can be omitted - but it's still the same form, an instantiation expression

[split plover]

Well ignoring the fact there wasn't an = in your example at all, you didn't tell me that until i had figured out i didn't need new in the first place

[slender nymph]

#💻┃code-beginner message
this literally shows you what you had wrong and what it should look like

[ivory bobcat]

Are you creating drama for no reason whatsoever? They're actually trying to inform you that you cannot use [ ... ] with c#9 and that you'd use the new int[]{...} pattern instead.

[polar acorn]

Yes, exactly, because I was telling you what to set the variable to, not the entire line. And you do need new

[slender nymph]

there wasn't an = in what they showed because what they showed belongs entirely on the right side of the = operator

[split plover]

I dont get it whats wrong with the first one here

[naive pawn]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/arrays

[naive pawn]

the former is not available in the version of c# that unity uses

[polar acorn]

You should actually read answers you're given

[split plover]

While i was chatting here i finished my code i was making and it works perfectly fine

[naive pawn]

and let me guess, you don't actually understand the array initialization

[naive pawn]

@split plover go give this a read
there's an entire infobox with ! Important about using collection expressions

[split plover]

i just put it as int[] DamageArrray = {} and it works perfectly

But if it works why am i being told to fix it.

[naive pawn]

you aren't lmao

[split plover]

thats my question

[naive pawn]

we're trying to get you to understand

[split plover]

I understand why my code works, what i dont understand is why im being told to do something that from my knowledge i dont even need to do

[naive pawn]

your knowledge is lacking then lol

[ivory bobcat]

Who told you {} doesn't work?
People have definitely told you [] wouldn't with C#9

[polar acorn]

You wanted to create it with values right?

[torn dragon]

if i create a button why is this so big

[split plover]

not wanted, i DID create it with values

[split plover]

just scale it down

[polar acorn]

How big is your canvas?

[naive pawn]

not a code question, see #💻┃unity-talk or #📲┃ui-ux

[polar acorn]

It looks like a reasonable size for a normal overlay canvas

[slender nymph]

because it is on your canvas which is much larger than you are expecting it to be because you appear to have gizmos disabled so you can't see its actual bounds

[split plover]

but its bigger than the entire map it looks like they're making

[naive pawn]

it doesn't exist beside the entire map (if it's an overlay)

[polar acorn]

Yes that's how canvases tend to work

They're the size of the screen, not the size of the world

[slender nymph]

if you don't understand how UI works you shouldn't go and try answering questions about UI

[split plover]

nvm mb i thought it was a button intended to be in the world

not enough context 😭

[polar acorn]

Where the button is in the actual world space doesn't matter, it's where it is in relation to the canvas

[torn dragon]

how do i scale it down

am making a start menu and it was fine before

now its super large

[naive pawn]

@torn dragon

[polar acorn]

You don't

[sour fulcrum]

Is there a official way to do the equivalent of
List myList get; private set;
But where they can only reference the list to iterate and etc? Not add/remove etc.
Usually i’d have a function that returns a copy of the list but ideally it would be nice to not make a whole copy every time

It’s fine if there’s no preferred way either i just don’t know

[polar acorn]

You would need to create your own implementation of list with different accessors

[slender nymph]

use IReadonlyCollection<T> as the type rather than List<T>, List implements that interface

[kindred axle]

its in a canvas, check the game tab. you'll see how it fits with the screen.
double click the canvas object so you can fiddle with your ui

[sour fulcrum]

Then remake it when i need to modify privately? (Which I’m guessing is kinda the same cost as modifying a list anyway(?))

[slender nymph]

just have a private field that you expose through the property. also use IReadOnlyList<T> rather than IReadOnlyCollection<T>, i forgot that the latter doesn't allow you to index into it

[sour fulcrum]

Ohhh ok i misassumed how they work, thats cool tech

Ty chefs

[split plover]

quick question, is it even possible to set an array's values to another array

been trying to find a way for nearly 30 minutes

[ivory bobcat]

New array with the other as an argument for the constructor

Assuming you aren't just wanting to reference the same instance

[split plover]

im gonna pretend like i know what this means and im gonna look up what an argument and constructor is really quick

[slender nymph]

there are beginner c# courses pinned in this channel, perhaps start there

[split plover]

okay got it im gonna do that

[split plover]

did the entire beginner unity c# courses and it did not go over how to set an array to another array from what i know

[slender nymph]

and you still don't understand basic things like what an argument or constructor are. so perhaps learn c# separately from unity

[split plover]

im good seems like a waste of time for me when i only need c# for unity and nothing else

usually i dont need to ask here for my questions and i can just look it up but with arrays there is very little online 😭

[sour fulcrum]

(I get what you guys are trying to teach to Fusion but also the basic tutorials don’t teach you how you could use constuctors to copy an array)

[sour fulcrum]

There is so much online

[slender nymph]

refusing to learn the basics of the language you need to know for unity is going to fuck you over in the long run. but good luck or whatever, i block people who refuse to bother learning 🤷‍♂️

[split plover]

I couldn't find anything

[split plover]

im fine with learning

[sour fulcrum]

What did you search

[ivory bobcat]

You could clone and cast to your specific type instead since you're using a primitive array
https://learn.microsoft.com/en-us/dotnet/api/system.array.clone?view=net-9.0

[sour fulcrum]

Googling is unironically a very crucial skill to build up

[split plover]

I just searched up how to set an array to another array

[sour fulcrum]

What did it come up with

[split plover]

a bunch of unity discussion forums that were on an entirely different topic

like one that is asking how to copy an array (not set an array to another array just straight up cloning an array without changing the name or anything)

[ivory bobcat]

For example cs int[] arr = {...}; int[] clone = (int[])arr.Clone();//Shallow copy

[split plover]

slightly confused on this

oh

nvm

[split plover]

i didn't know you could use it like that honestly

[naive pawn]

unity c# courses teach c# in unity.
there's still normal c# things you have to learn that aren't related to unity.

[split plover]

but if i have to learn it to use it in unity wouldn't that be related to unity

[naive pawn]

no

[kindred axle]

theres lots of unity specific things in c#

so the courses won't go over everything

[torn dragon]

why can i not see OnStartClick() there

[slender nymph]

unrelated to your issue, but related to the rules of getting help in this server: you need to get your !IDE configured 👇

[naive pawn]

you're not gonna learn much about general things like int vs long or structs or linq or inheritance or constructors in "c# for unity", because those aren't unity things. those are c# things. and there are c# articles that cover that, so there's no need to repeat all that content in unity-specific guides

[eternal falcon]

💡 IDE Configuration

If your IDE is not autocompleting code
or underlining errors, please configure it.

Select one:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)
• VS Code
• JetBrains Rider
• :question: Other/None

[split plover]

man this would be so much easier if i didn't have to try to set one array to different arrays based on what is happening 😭

[naive pawn]

also, do you actually need a clone

if you just need a reference you can just.. assign the array

[split plover]

I tried assigning the set array to the array it has to be set to but it didn't work

[naive pawn]

i have no idea what you're trying to say there lmao

stop saying "didn't work", that's not really useful
give some info about what the issue is

[ivory bobcat]

What're you trying to do exactly?

[split plover]

At this point i dont even know i just want something set up so that i can change stuff like movement speed based on what character is selected and right now im trying to set an array to another array but its super confusing

[slender nymph]

classic XY problem

[naive pawn]

• why are you using an array for that (why not a struct)
• why are you using an array for that (why not an SO)
• so.. you can just assign that, no need to clone

[split plover]

fuck this i don't care about optimization im just gonna copypaste code like i was trying to avoid

[split plover]

wdym struct?

[naive pawn]

optimization is nowhere near a concern

the issue is you're painting yourself into a corner

https://xyproblem.info

[naive pawn]

and that's why you also do the normal c# courses instead of just the unity-specific ones

[split plover]

well

if optimization isn't an issue im gonna just copypaste some code really qucik

[naive pawn]

structs are bundles of data, like arrays
the difference is you get names and you can have different types

[naive pawn]

the issue with the copypaste is not optimization

the issue is you're fucking over your future self

and we've been trying to stop you from doing that and you're just hellbent on doing it apparently

[rocky canyon]

did you add the monobehaviour to a gameobject and drag that gameobject into the slot in the button?
or did u drag the script itself (from the project window)

[ivory bobcat]

We're not sure what they're using their array for though - other than holding values.

[split plover]

im just copypasting stuff to other scripts so i can do attacks and stuff since they will have varying cooldowns and damage in different scripts

[naive pawn]

why are you even asking stuff here if you're just going to ignore everything we recommend lmao

not gonna waste my effort if you refuse to accept help, cya

[split plover]

i would've never come to the conclusion that my idea was stupid if i didn't know the problem was me being stupid in terms of what im trying to do and not me not being able to do it

[torn dragon]

i fixed it, i did not add scene management in the code

[ivory bobcat]

I do not believe anyone called you or referred to you as unintelligent

[split plover]

i did

i called or reffered to myself as unintelligent

[sour fulcrum]

Anyone trying isn’t stupid 🫡

[split plover]

im trying and im stupid though

[naive pawn]

but that's not the issue, the issue is you're refusing to put any effort into changing that

[split plover]

I already know what im going to do and its going to be much easier than what i was trying to do anyways so

[vast cairn]

should i manipulate the color via script

[ivory bobcat]

That's fairly interesting, although not code related #💻┃unity-talk
Perhaps you've got some lighting/shader in the scene that alters the color presented (how it looks like after fully rendered).
Either way, it isn't a code question.

[vast cairn]

sorry i didnt know where to ask lol

[ivory bobcat]

#💻┃unity-talk would be the general non-coding channel

[ivory bobcat]

Maybe post the specific error as well

An image of the console error in detail would suffice

[split plover]

I dont know if it will help much but you should still add System.Collections

makes sense

Google isn't giving me any answers that involve the interfaces themselves inheriting; Can I not do this kinda thing?

    public interface IBaseTest
    {
        public string GetCoolString();
    }

    public interface IEpicTest : IBaseTest
    {

    }

    public interface IRadicalTest : IBaseTest
    {

    }

    public class FullySickClass : IEpicTest, IRadicalTest
    {
        public string IEpicTest.GetCoolString() => "so cool":
        public string IRadicalTest.GetCoolString() => "woah";
    }

[rocky gale]

interesting idea

it doesnt work?

[sour fulcrum]

i know i can do

    public interface IEpicTest
    {
        public string GetCoolString();
    }

    public interface IRadicalTest
    {
        public string GetCoolString();
    }

    public class FullySickClass : IEpicTest, IRadicalTest
    {
        public string IEpicTest.GetCoolString() => "so cool":
        public string IRadicalTest.GetCoolString() => "woah";
    }

[rocky gale]

damn

[eternal needle]

both are IBaseTest so just public string GetCoolString() => "so cool"; is needed. If you are purposely trying to have 2 different method implementations then I think they should be separate interfaces

[sour fulcrum]

I do have two different answers yeah, theres some other stuff in here that makes me wanna keep them not-seperate so if i can't do it like i wanted there i'll have to think of another way to handle this

[eternal needle]

well you want separate method implementations so it should be separate. im not sure what you're trying to do here so its hard to say. think of it like this if that code compiled: what should happen if a class references your FullySickClass as type IBaseTest? Which of these 2 get called?

[sour fulcrum]

ah that makes more sense

[ripe dock]

using UnityEngine;

public class HumanControl : MonoBehaviour
{
    public float moveSpeed = 5f;
    public Rigidbody2D rb;
    private HumanControls humanControls;
    private Vector2 moveInput;
    private void Awake()
    {
        humanControls = new HumanControls();
    }

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

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

    void Start()
    {
        rb = GetComponent<Rigidbody2D>();
    }

    void Update()
    {
        Vector2 moveInput = humanControls.Land.Move.ReadValue<Vector2>();
        Debug.Log(moveInput);
        if (humanControls.Land.Dash.triggered)
        { 
            Debug.Log("Dash"); 
        }
           
    }
    void FixedUpdate()
    {
        rb.AddForce(Time.fixedDeltaTime * moveSpeed * moveInput);
    }
}

My character is not moving when there's any input, but it's still moved with gravity and such. What am I doing wrong?
My goal is to make an addforce-driven 2D top-down game character control

Both Debug.Log seem to be correct

[slender nymph]

you're creating a local variable called moveInput and assigning the input to that, logging it, then throwing that value away because you don't use it.
you also never assign to the field called moveInput so it's always the same as Vector2.zero when you use it in AddForce

[ripe dock]

Thanks, I just removed Vector2 and it helped

[chrome shadow]

i currently have a rigidbody character controller, and i want the player to fall faster, i tried doubling the mass and jump force, meaning it should theoretically fall faster while jumping to a similar height, but the jump and fall speed ended up the same. How can i fix this?

My jump code:

    private void Jump()
    {
        // Apply jump force
        Ctx.Rb.linearVelocity = new Vector3(Ctx.Rb.linearVelocity.x, 0f, Ctx.Rb.linearVelocity.z);
        Ctx.Rb.AddForce(Ctx.transform.up * Ctx.JumpForce, ForceMode.Impulse);

        // Reset jump input and set cooldown
        Ctx.Input.jump = false;
        Ctx.JumpCooldownDelta = Ctx.JumpCooldown;

        // Trigger jump animation
        Ctx.Animator.SetBool(Ctx.AnimIDJump, true);
    }

[keen dew]

Gravity famously affects all objects the same regardless of mass

If you want to fall faster you'll have to either increase gravity or apply downward force while falling

[chrome shadow]

ahh ok

[keen dew]

Also check that the scale is correct, often when the objects look like they're falling too slow it's because they're too big. The player model should be about 2 units high which makes it feel the most natural

[chrome shadow]

the scale of the object with rigidbody is 1,1,1

[keen dew]

I meant scale in a more general sense

How tall is the object?

[chrome shadow]

well uh its a squirrel and its pretty tiny

[keen dew]

How tall is pretty tiny in numbers?

[chrome shadow]

the squirrel rig is scaled up 3 times

and its parented to an empty

with a scale of 1,1,1

[keen dew]

That doesn't tell anything

The model might be 1 cm tall or 100 meters tall

[chrome shadow]

uhhhh wdym

[keen dew]

Ok let's put it this way. When you jump, pause the game. What is the Y coordinate of the squirrel at that point?

when the jump is at the highest

[chrome shadow]

around 2.4

[keen dew]

Ok that's somewhat normal

[chrome shadow]

alr nice

[topaz mortar]

How does Physics2D.CircleCast work exactly?
Does it just return the first target hit in general? Or the first target for each "point" on the circle?
So if I had a target in front and behind me, would a circle cast return both? Or just the one hit first?

[pallid nymph]

I'd recommend reading the docs and/or just testing it.
There are different overloads - some get a single hit, some get all hits. I don't remember if it'll count the initial objects overlapping as hits, or only if the circle would hit something as it's moving. It's only moving in one direction, so it wouldn't hit something "behind" unless if it maybe overlaps the start point circle and those hits are included.

[rich ice]

first one hit

[topaz mortar]

yeah I checked the docs, just wasn't sure, thx

Sorry, I'm very new to both Unity and C#

I guess the solution to it would be using the input events system. When pressed - invoke event, perform a dash

Oh, this

[eternal needle]

https://unity.huh.how/unity-events/incorrect-assignment
the unity event part there seems wrong

you definitely could do it through c# events as well but if you're very new to both then this unity event is easier for now

[ripe dock]

I added it from Project

Lemme try it out (my Unity successfully crashed lol)

[eternal needle]

yes thats not what you want to do. you want the unity event to reference your specific component as the link above shows in a video

[ripe dock]

You're a life savior ❤️

Took me multiple hours to try and fix it myself

Maybe trying to make it event-based as a beginner was a bad idea 😁

[eternal needle]

the new input system definitely has a learning curve to. one file you sent is the generated c# class for that input action asset. You might not need that if you don't plan to subscribe things in code (c# events) for now. It might just confuse you more atm

[nimble apex]

new system input is quite different , but it really helps a lot by making all the mapping clear

[eternal needle]

though i see your code does actually use that HumanControls class

[ripe dock]

I completed the essentials tutorial and it used the old system. While simpler for beginners, it's just bruh

I use camera relative movement and whenever I press backwards on the movement my character spins left or right

Hello everybody, i'm kinda new in unity development. i have a problem with my game. when i'm moving the character and camera, there is a jitter effect (i don t know if it's the correct term). I added a script for movement (https://pastebin.com/PA1v253c). do you have any ideas how could i solve this issue? thanks!

changed, thanks

moving keyboard input to FixedUpdate and mouse input to LateUpdate fixed the jitter effect, but the camera is still not as smooth as i want to be.

do you use Cinemachine?

[hexed terrace]

The CM brain needs to be set to use the same Update method as your movement

[past yarrow]

Is there a Data Structure that combines both the stack and the queue concepts together so I can push / pop at the start and push / pop at the end please ?

[wintry quarry]

You want a Linked List

[sharp bloom]

How much performance is lost by calling Animator.Play() with a string instead of hash?

Or does it matter very much?

[hexed terrace]

You'd probably need to be doing thousands of calls per frame for it to make a difference

[sharp bloom]

Yeah I thought it might be like that

[sharp bloom]

Yeah I was super confused for the first few days I used it, then suddenly it just clicked.

I found the PlayerInput component unintuitive, for me it was much easier to use the provided C# class directly

[sharp bloom]

Ah yes, the thing every CS class makes you to implement

[eternal needle]

https://docs.unity3d.com/ScriptReference/Animator.Play.html

When you use the stateName parameter, this method calls Animator.StringToHash internally
seems to be the only difference. the docs for StringToHash says it uses CRC32 so you could find performance related to that. or just run Animator.StringToHash() a bunch of times using the profiler to see the effect of calling it like 100, 1k, or 10k times per frame

[nova bluff]

thanks

[wintry quarry]

One of many

[naive pawn]

this is called a deque (pronounced like "deck"), for double ended queue
c# implements it with linkedlist as mentioned above

[past yarrow]

Thanks 👍

[charred spoke]

It’s more like hundreds before the garbage from the string becomes a problem

[charred spoke]

It’s always better to use a hash

[nova bluff]

Still can't find a proper solution for jittering. If the other objects does not jitter, the character body it's jittering. If the character body does not jitter, the other objects will (as shown in video). I just can't make it work. https://pastebin.com/ztV4U3H9. Do you please have any ideas? Thanks!

[wintry quarry]

You're makijng a classic error here

transform.rotation = Quaternion.Euler(0f, yRotation, 0f);```

[rich adder]

we need a bot command everytime this issues comes up lol

[nova bluff]

should use slerp?

[wintry quarry]

If you have a Rigidbody you should not be touching or modifying the Transform directly, period

[wintry quarry]

no

rotate the Rigidbody, not the Transform

Rigidbody.rotation = Quaternion.Euler(0f, yRotation, 0f);```

ALso you are doing this rotation in FixedUpdate

FixedUpdate is not synchronoized with the rendering loop

character rotation should happen in Update

So two things:

• rotate in Update
• rotate with the Rigidbody not the Transform

also ensure that interpolation is enabled on your Rigidbody

[nova bluff]

same problem.

• Interpolation it's enabled on Rigidbody
• I moved Rigidbody.rotation in Update function
• Removed transform.rotation

    void Update()
    {
        ListenMouseMovementInput();
        CameraHolder.transform.SetPositionAndRotation(RigidBody.position + CameraHolderOffset, Quaternion.Euler(xRotation, yRotation, 0f));
        RigidBody.rotation = Quaternion.Euler(0f, yRotation, 0f);
    }

    private void FixedUpdate()
    {
        ListenKeyboardInput();
        MovePlayer();
    }```

[wintry quarry]

show MovePlayer

[nova bluff]

    void MovePlayer()
    {
        if (moveDirection != Vector3.zero)
        {
            float speed = MoveSpeed * (Keyboard.current.shiftKey.isPressed ? RunSpeedMultiplier : 1f);

            Vector3 targetPosition = RigidBody.position + speed * Time.deltaTime * moveDirection;
            RigidBody.MovePosition(targetPosition);
        }
    }```

[wintry quarry]

you sure you want to be using MovePosition?

Instead of just setting velocity?

MovePosition is really only a thing for kinematic bodies

[nova bluff]

enabling kinematic in rigidbody removes jittering

but i don't have gravity

[wintry quarry]

I'm not telling you to make it kinematic

I'm telling you you shouldn't be using MovePosition unless it's kinematic

e.g. instead of:

            Vector3 targetPosition = RigidBody.position + speed * Time.deltaTime * moveDirection;
            RigidBody.MovePosition(targetPosition);```
You would do this:
```cs
Vector3 velocity = speed * moveDirection;
velocity.y = Rigidbody.linearVelocity.y;
Rigidbody.linearVelocity = velocity;```

[rich adder]

should rb.rotation be .MoveRotation, or is that just for interpolation ?

[rocky gale]

Whats difference between linearVelocity and just velocity

[wintry quarry]

It was renamed to linearVelocity in Unity 6

[naive pawn]

velocity is the old version of linearVelocity

[wintry quarry]

it's the same thing

[rocky gale]

Oh really?

[frail hawk]

yeah, a major and very important thing unity had to change..

[rocky gale]

😂

[wintry quarry]

You can do MoveRotation only if you're doing it in FixedUpdate but then you have a nightmare with how to handle mouse input. So it's easier to just use rotation directly and put it in Update

[rich adder]

ahh that makes sense ty

[rich adder]

clarity.
Linear means moving straight line
Angular means rotation

[rocky gale]

It wasn’t angular before tho

[naive pawn]

it was

[rich adder]

rb.angularVelocity

[rocky gale]

Oh that

Wait

[nova bluff]

    void MovePlayer()
    {
        if (moveDirection != Vector3.zero)
        {
            float speed = MoveSpeed * (Keyboard.current.shiftKey.isPressed ? RunSpeedMultiplier : 1f);

            Vector3 horizontalVelocity = moveDirection * speed;
            RigidBody.linearVelocity = new Vector3(horizontalVelocity.x, RigidBody.linearVelocity.y, horizontalVelocity.z);

        }
    }```

Jittering it's still present and my character it's bouncy

[rich adder]

rb.velocity can be ambiguous if u are more technical with physics functions

[rocky gale]

Did they change rb.velocity or rb.angularVelocity

[rich adder]

no

[naive pawn]

before, we had velocity, angularVelocity, drag, angularDrag
after unity 6, it's linearVelocity, angularVelocity, linearDamping, angularDamping

[rich adder]

@rocky gale im saying they put linear to better distinguish it from from angular functions

[rocky gale]

Ok

[torn dragon]

how do i add a death screen and respawn key after my characters dies in game

the game is almost done

[rich adder]

create a script and a gameobject for the visuals 🤷‍♂️

[torn dragon]

didnt help

[rich adder]

break it down.
how do i add a death screen?

respawn key after my characters dies in game?
-- vague af still but, "how to capture a keypress in unity"

DeathMethod()

[rocky canyon]

it works!! 💪

    [Serializable]
    public class BindingSaveData
    {
        public string actionName;
        public string overridePath;
    }

    [Serializable]
    public class BindingsSaveFile
    {
        public List<BindingSaveData> bindings = new List<BindingSaveData>();
    }``` this is how im keeping up with the data. (and can see the text file next door)
just wondering if this is reliable +/or the way u guys would do it

- if you start and the file is there it loads in the file
- if you start and the file is missing it starts with the default binds in the actionmap
- once u finish it always loads the json..
(probably need a button for defaults but i **think** i shouldnt need to keep data on the defaults b/c they're already stored in the map..)

i currently using an actionmap with just a few button actions..
im actually unsure how the system works.. but the action maps all have just 1 bind..
that way when we rebind we can use keyboard, mouse, or gamepad (and all together)

only needing to overload the 0. i guess is whats stored in the memory

ive taken snippets here and there and built it up.. the syntax is something im still getting used to
and soo far i've only made it work with Button inputs... i figure the composite stuff is gonna be a bit harder

https://www.nombin.dev/sws7e79c5cgc9868harn2ltd my full rebind method if anyone wants to check and see if its pretty normal looking 😅

TLDR: im pretty sure im on the right path.. but i was just thinking of default values..
from what i understand the new system (if rebinding) just uses values in memory and doesnt actually change the map.. soo for default settings i actually dont really need to store those anywhere b/c they'll always be there..

you want it to have gravity?

you set it to not have gravity in Start

No, i want zero gravuity but when i am fly around, if i go to hit off a wall or smth it doesnt work. i either slide, or i push my self out and i only go asd far as my arm extention

can u help?

[final trellis]

how come when i try to make this line renderer not align with view it just vanishes

[final trellis]

or do i not understand the Transform Z Alignment option

[scarlet tundra]

Whats the best way to get a normal / curvature of an object, the normal with raycasting or?

[rocky canyon]

thats how i do..

raycast from camera forward.. or raycast with an offset vertically and raycast down

[scarlet tundra]

I guess I just answered my own question I'll be doing that then

[rocky canyon]

use the RaycastHit and just grab the .normal from it

[scarlet tundra]

Yeah, thanks!

What if I didn't want to use a mesh collider? ( I need to find the mesh's curvature ) it's kind of hard to explain, I can't use basic primitive colliders (e.g. box, sphere, capsule, and not mesh as it would be too performance heavy for what I'm trying to do.

[rocky canyon]

well u sorta have to..

raycasts detect colliders..

not meshs'

[scarlet tundra]

Yeah I know that's why I'm at a dilemma

[rocky canyon]

ya, that im not exactly sure of..

[scarlet tundra]

I could use spline to get the curvature but I'm not sure that would do exactly what I'd want

[rocky canyon]

ya i wouldnt know how to do that either.. i can google around a bit.. maybe someone else can chime in 🔔

[scarlet tundra]

You don't really know the context though, how would you?

[rocky canyon]

Barycentric Interpolation

lol.

[scarlet tundra]

What the?

For splines I see

[rocky canyon]

lol.. im not doing well w/ context either

https://docs.unity3d.com/6000.1/Documentation/ScriptReference/Mesh-normals.html

^ might be something to this

[scarlet tundra]

Basically, VR, hand I already made the grabbing system with a pole that is flexible (as in size) it's just that it didn't quite handle curvature at all nor did it handle

[rocky canyon]

im not sure how u'd go about sorting thru it tho

[scarlet tundra]

I'll look into that

Yeah I don't know how I'd be able to take the speccific normal with raycasts

[rocky canyon]

ahh yea... this is like shader territory

[scarlet tundra]

Yikes I'm not ready for that

[rocky canyon]

im seeing things that say using a mesh collider and raycasts would probably be more performant than you'd expect

and alternative methods of going thru all the vertices and stuff would actually be less performant

unity, surface normal of mesh without collider is what im using to search with

https://discussions.unity.com/t/how-could-i-instance-on-the-normal-of-a-surface-without-using-colliders/152618

[scarlet tundra]

Yeah I'm seeing that now maybe It'd be just better to do that

And yeah since I'm literally only doing it one frame it wouldn't be that performance heavy

[rocky canyon]

but i did learn something.. that bary thing seems like a default way..
if you have a TRI.. u have 3 verts.. and using those verts u can calculate the normal

[rocky canyon]

could just test to see ¯_(ツ)_/¯

[scarlet tundra]

But again calculating the closest vertex would be costly

[rocky canyon]

u never know

[scarlet tundra]

Yeah I'd better try hopefully using mesh colliders won't be performance heavy in general in the long run 🤷

[rocky canyon]

if ur concerned about them.. im not sure the operation ur doing...
but if its only needed at a certain time.. u could probably just leave it disabled until u need it

enable it.. do ur thing.. and then disable it again

[final trellis]

any help with this?

[rocky canyon]

theres really only 2 options.. (align with Z and align with Cam) afaik

[scarlet tundra]

Most if not everything will be physics based related to the player, ex. an item on the ground

That's why I'm concerned for performance just random items around

[rocky canyon]

as long as u dont have 1000s of em im sure ur fine..

unity is pretty optimized in regards to physics

[scarlet tundra]

Alright thanks for your contribution!

[final trellis]

yeah ik, but like, what even does 'align with Z' even mean, ik its prob a dumb question but i cant get it for the life of me 😭

[rocky canyon]

it means like if ur looking at it from its local Z axis ull see it as it should be

if u end up looking DOWN it.. for example.. it'll be a sliver of pixel..

or the backside.. = nothing

[final trellis]

i should prob mention what its even for if the answer isnt gonna be as simple as i thought ( unless theres just a thing im missing that makes it work idk )

im trying to make a simple sword slash effect, where theres a list of points and every frame those points are added to the list of points a line renderer, so it gives the effect of a sword slash

[final trellis]

i assume unless the material being used is double sided

[final trellis]

the reason why it cant align with view is bc it'd look really odd from the wrong angles

[final trellis]

now im confused, bc that sounds like exactly what im expecting it to do, but it wont

but rn its all weird and jittery

[rocky canyon]

heres best example i can give

with Z option chosen when we rotate the linerenderer object itself you'll see that it can only be seen from the front.. (0,0,-10) or something...

with the Align with View option.. we can rotate all the way around it.. (and it'll still be visible)
as its then acting like a billboard.. (like a 2D tree that rotates to always face the camera)

[final trellis]

how come its just.... not visible at rotation 0, 0, 0

for my end

im using a double sided material and at 0, 0, 0 rotation, theres no angle where its visible

[rocky canyon]

well, for 1 im showing an example thats rotating the linerenderer object..

ur not rotating the actual line renderer object..

ur just rotating the sword

[final trellis]

but its rotating alongside it? or does that not count

[rocky canyon]

🤔 hmmm

i dont believe that counts.. its LOCAL would still always be the same

if its set to 0,0,0 and its a child of the sword.. no matter how u move the sword around.. its still gonna be 0,0,0 rotation.. relative to the sword

im not sure if that matters... or if its the global values its using..

[final trellis]

i think its gotta, bc you can see it rotating in and out of existence

this shits really weird

[rocky canyon]

im not gonna lie.. im not the best with line renderers 😄

i usually find a setup that looks good and move along

[final trellis]

it looks like how a 2d creature would percieve a 3d object moving along the axis it cant comprehend

[rocky canyon]

but ur using the trail renderer right?

and not actually the line renderer

[final trellis]

oh thats a thing?

😭

FUCK

[rocky canyon]

i believe they kinda work the same

but i dont know the specifics

a trail renderer would be what i assume ur looking for

if u want a trail for a swinging weapon

[final trellis]

lesson learned: someone mightve already done the thing youre looking to make and its even built-in

[rocky canyon]

😄

trails are set to automatically align with view..(iirc) so it may work right out the box..

[modern aurora]

complete beginner here, could use a hand with something simple that im a bit too dense to figure out atm.

using UnityEngine;

public class TileController : MonoBehaviour
{
    public GameObject endPos;
    public GameObject startPos;
    public GameObject tile;

    // Update is called once per frame
    void Update()
    {
        if (endPos.transform.position.z = 48);
        {
            Instantiate(tile, new Vector3(0, 0, transform.position.z), transform.rotation);
        }
    }
}

im getting an error CS1612 in the if statement. trying to spawn a new tile whenever endpos reaches z = 48

[scarlet tundra]

= is to assign, == is to compare

so it'd be endPos.transform.position.z == 48 (in your if statement)

[modern aurora]

🤦 thank you

[scarlet tundra]

Happens from time to time don't worry

[naive pawn]

don't beat yourself up, it's a rite of passage lol

still happens to me with a solid 4 years of experience

[scarlet tundra]

Exactly

[wintry quarry]

checking for an exact magic number position like that is also... it's not good practice

this code is very weird

[modern aurora]

i dont doubt it, i have absolutely no idea what im doing

the code is now spawning a tile on every frame

[stuck field]

Should head to !learn then, will teach you a lot going through the pathways

[eternal falcon]

:teacher: Unity Learn ↗

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

[wintry quarry]

yes, that's expected with this code

Update runs every frame

It's not clear what the intent of this code is at all

[modern aurora]

infinite runner game. rather than moving the player, im moving the world around the player, so when a tile reaches a certain point im trying to spawn a new tile in its original place

[glossy current]

Trying to turn my character, but for some reason I cant turn right or left? Up and down works just fine, even though the scripts are almost the same.

[scarlet tundra]

Use the new input system for one (its powerful in some scenarios) and for another don't separate the different euler rotations into different classes

[glossy current]

Am I not using the new input system? I looked up a guide and I thought I was. I separated them because the up and down moves the characters head and the left and right moves the entire character.

[scarlet tundra]

Hold on

[naive pawn]

yeah that's the new input system

[scarlet tundra]

Yeah I just realized it was

But in general the rotations shouldn't be handled in two separate scripts

[glossy current]

How should I then separate it if I want one to rotate the whole body and the other to only rotate the head?

[rich adder]

btw you should not be using Time.deltaTime on mouseInput

do you have any other scripts on the player ? also use links don't use screenshots for !code 👇

[glossy current]

Ok, can you explain why? I'm a little confused on how it works, I get it standardizes things between frame rates but i'm just a little confused on when to use it and when not to

I have an unused character health script and template script that only contain a few variables right now.

no methods or anything

[rich adder]

normally time.deltaTime is used to give you the time it took since last frame to render, to give consistent increase/decrease of values so its framerate independent.
MouseInput is already returning the delta (movement between frames) so its already framerate independent

[naive pawn]

deltaTime is the time in seconds since the last frame, so it's in units of seconds per frame - it's a conversion factor
sometimes you have things in x per second, and you need to convert that into x per frame - that's where you use deltaTime
but sometimes you don't need to convert
sometimes you want things in x per second, like rb velocity
sometimes you already have things in x per frame, like mouse input

[glossy current]

Oh ok I see

Ok I got rid of that but any idea why I'm getting the stuttering and lockup?

and if I should combine the two rotation scripts, how should I split movement between the head and body

[rich adder]

where exactly did you put these scripts, which gameobject

[hollow field]

Does Input.GetKeyDown() only return true on the first frame the key is pressed?

[rich adder]

I would

[rich adder]

yes

[glossy current]

the left and right rotation is on the body, which is the parent to the head. the head has the up and down rotation script

[hollow field]

thats what I thought but it appears to be running things twice

[rich adder]

i would combine them into one script and just create a reference of each transform
eg: [SerializeField] private Transform headTransform [SerializeField] private Transform bodyTransform
and put them on the root of player

[rich adder]

how do you mean? in what way did you test this

[hollow field]

else if (Input.GetKeyDown(KeyCode.Space) && gameRunning) {
    Debug.Log("[SPACE] pressed during game!");
    if (score + 0.5 <= currentTimer.timer && currentTimer.timer <= score + 1.5) {
        currentTimer.timer = 0.0f;
        rotateMark.direction *= -1;
        score++;
        infoText.text = "Click when the timer reaches " + (score + 1) + " seconds.";
        rotateMark.resetMarker();
    }
    else{
        Debug.Log("TOO EARLY!!!");
        GameOver();
    }
}```
If player presses space while game is running, check if they pressed it within a certain time window.  If they press too early, run the GameOver() method. The issue is, it triggers the first if but then re-runs the whole thing and since the first if sets the timer to 0, it will trigger the else segment

[rich adder]

are you getting two ?
Debug.Log("[SPACE] pressed during game!");
