[rich adder]

basically a moveTowards a target

should be fairly simple

[thorn kiln]

I always thought it was really cool but poorly implemented in the games

[rich adder]

get the nearest target or whichever way to determine the target

[wind raptor]

I understand. Not trying to obfuscate, and it may not be worth the effort to explain the wider context when I'm almost certainly overthinking any performance issues.

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

public class IndicatorScript : MonoBehaviour
{
    public Material indicatorOFF;
    public Material indicatorON;
    private bool isIndicatorOn = false;
    private MeshRenderer indicatorRenderer;
    private Coroutine indRoutine;
    // Start is called before the first frame update
    void Start()
    {
        indicatorRenderer = GetComponent<MeshRenderer>();
        if (indicatorRenderer == null)
        {
            Debug.LogError("MeshRenderer component not found on GameObject.");
        }
    }

    // Update is called once per frame
    void Update()
    
    {
        if(Input.GetButtonDown("RIndicator")&&isIndicatorOn==false)
        {
            isIndicatorOn = true;
            Debug.Log("Start");
            if(isIndicatorOn){
                indRoutine = StartCoroutine(IndicatorCoroutine());
            }
        }
    }

    private IEnumerator IndicatorCoroutine()
        {
            while (isIndicatorOn)
            {
                indicatorRenderer.material = indicatorON;
                yield return new WaitForSeconds(0.5f);
                indicatorRenderer.material = indicatorOFF;
                yield return new WaitForSeconds(0.5f);
                Debug.Log(isIndicatorOn);
                if(Input.GetButtonDown("RIndicator") && isIndicatorOn==true)
            {
                Debug.Log("indicatoroff");
                isIndicatorOn = false;
                indicatorRenderer.material = indicatorOFF;
                StopCoroutine(indRoutine); // Turn off the indicator immediately
            }
            }
        }
}

Here i want to turn on my vehicle's indicator light on when i press the RIndicator button and off when i press it again. However it never seems to enter the if condition in the while loop, i check using the Debug.Log, why does it not enter the if condition, my indicator does not turn off

[summer stump]

In the future, with scripts this long, use a paste site

[eternal needle]

The actual dash would be easy, the hardest part is gonna be implementing this alongside your movement code. Likely would be easiest as a state machine

[supple needle]

Ok mb

[teal viper]

Checking input in a coroutine like that is gonna be unreliable.

[supple needle]

So what should i do?

[summer stump]

Just remove the isIndicatorOn condition from update

And have it either start or stop the coroutine inside that condition depending on its current state

Coroutine routine = StartCoroutine()

You can store the instance to the currently running coroutine in order to stop it easily

[teal viper]

I'm not sure that's the problem.

[supple needle]

Ok, but i want it to stop when i press the key again right? So what if it just restarts the coroutine?

[summer stump]

And do a toggle like this isIndicatorOn = !isIndicatorOn

[summer stump]

No, I just meant for an entirely new way of doing it

[teal viper]

Check it in update and cache the input. If it's true, only reset it to false after processing it.

[summer stump]

Imo, the coroutine should only handle blinking

[teal viper]

Yeah, refactoring the coroutine might be a good idea.

[rich adder]

yeah you'd need some precise skill to call that button down there

[supple needle]

Is that like a one frame thing?

[summer stump]

Is what like that?

Oh, for the coroutine to catch the update? Yeah

One frame every second

[supple needle]

I see, so i get rid of the condition to check for the button from the coroutine and throw it into the update condition

[summer stump]

Nah, use the same condition you have already

[supple needle]

Just dont put it in the coroutine?

[rich adder]

GetKeyDown is one frame yes

[summer stump]

    // Update is called once per frame
    void Update()
    
    {
        if(Input.GetButtonDown("RIndicator"))
        {
            isIndicatorOn = !isIndicatorOn;
            Debug.Log("Start");
            if(isIndicatorOn){
                indRoutine = StartCoroutine(IndicatorCoroutine());
            }
             else StopCoroutind(indRoutine);
        }
    }

    private IEnumerator IndicatorCoroutine()
        {
            while (isIndicatorOn)
            {
                indicatorRenderer.material = indicatorON;
                yield return new WaitForSeconds(0.5f);
                indicatorRenderer.material = indicatorOFF;
                yield return new WaitForSeconds(0.5f);
                Debug.Log(isIndicatorOn);
            }
        }
}

Rough code cause I'm on my phone

The check inside update needs to have an internal if to turn on or off the coroutine

[supple needle]

You got rid of the part that turns it off, so what ur trying to tell me is if i press the button again i toggle the isIndicatorOn value in the update and it doesn't access the coroutine right?

[supple needle]

Yep

Gotcha

Thank you

[summer stump]

I updated it, but this way indRoutine still needs to he checked if it is null or something. But that should give you an idea

Phone coding just sucks haha

[supple needle]

Ye its hard to read

[frigid sequoia]

Can I make a value show in the inspector but be inmodifiable? Cause I would assume is just tag it as [Read Only] but it is not letting me

[rich adder]

ReadOnly attribute is NaughtyAttributes or Odin

otherwise you can inspect private values with Debug mode in inspector

[frigid sequoia]

You mean Debug.Log? Cause I would very much prefer to have the values showm on the item that I am checking than having a thousand console logs

[rich adder]

nah I mean you can pop out the script and press Debug mode in the inspector, let me show you

[supple needle]

Just tried it and it works! Really appreciate it, now that i look at the code, it makes so much more sense lol

[frigid sequoia]

Ooooh, that's actually reaaaally usefull

Thxs 😄

[rich adder]

[summer stump]

Awesome, glad you got it!

[frigid sequoia]

Ok, so I have literally done anything today other than refactor code and references; probably I would still be missing some parts, tomorrow I will probably yet find several null reference exceptions aaaaand my internet just run out for the third time... But still I think today I learnt a lot more than other days where I did tangible stuff, so thank you for that guys 😄

[rich adder]

awesome work! you're in the beginning stages anyway, where you need to basically start creating your own workflow based on what you learn and refactor, once you get that going it gets easier and easier

[cobalt creek]

so someone other day rec'd me to use cooldown, so i made this script

// Update is called once per frame
    void Update()
    {
        if(comp.cooldown > 0)
        {
            comp.cooldown--;
        }
        //Debug.Log(comp.cooldown);
    }
    
    public void refreshServerList()
    {
        //delay
        if(comp.cooldown == 0)
        {
            comp.cooldown = 1000;
        }
        else if(comp.cooldown > 0)
        {
            return;
        }
        //...

is this ok or is there better option?

[rich adder]

you should never compare float with == btw

[cobalt creek]

ok

[rich adder]

https://docs.unity3d.com/ScriptReference/Time-time.html

has good example of doing a small timer/cooldown

You can use Coroutine too

[gentle marsh]

Anyone got a good tutorial of how to make vr boxing game?

[rich adder]

thats a very specific thing, not likely to find something like that lol

[cobalt creek]

thank

[gentle marsh]

aw ok

do you know any way to get started

[rich adder]

Yeah I would start with the Unity VR learning path

doing boxing should be easy once you figure out how to even move hands, the rest is easy collider work

https://learn.unity.com/learn/pathway/vr-development

[summer stump]

@cobalt creek IS it a float? Seems like an int?

Generally timers are done by subtracting Time.deltaTime from a float

But you just decrement a value every frame
Which means it will be faster and slower on different computers
DEFINITELY not how you want to do it

[cobalt creek]

no, it not a float, it a variable from a script with my own custom namespace

[summer stump]

well, where it comes from is irrelevant. It's either a float or int

[cobalt creek]

int sorry

[summer stump]

Gotcha

[rich adder]

int for cooldown ?

[summer stump]

yeah, then a == comparison is fine
(Ignoring that doing a timer like this is bad)

[rich adder]

but yeah I assumed it was float lol

[cobalt creek]

i consider float tho, maybe use (a-b)< tolerance

instead of ==

[rich adder]

no need

Mathf.Approximately

[cobalt creek]

thank you

[rich adder]

but yeah you should use Time.deltaTime for something like that

[summer stump]

void Update()
{
    if(comp.cooldown > 0)
    {
        comp.cooldown -= Time.deltaTime;
    }
    //Debug.Log(comp.cooldown);
}

public void refreshServerList()
{
    //delay
    if(Mathf.Approximately(comp.cooldown, 0))
    {
        comp.cooldown = cooldownTime;
    }
    else if(comp.cooldown > 0)
    {
        return;
    }
    //...

just slight changes as discussed so you can see

[cobalt creek]

thank

[summer stump]

But I would have the timer setting in update, and just call refreshServerList one time when the timer goes off (without even referencing the timer at all in that method)

Nav put an example link above

Oh, that was to Time.time, which is another way to do it

[foggy lark]

How do i fix this ?

Visual Studio guide

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

[quaint terrace]

i just learned about 'static' and i dont quite understand it but from what i am reading i can remove:

    public ImageDatabase imageDatabase;
    public ItemStorage itemStorage;
    public JobManager jobManager;``` 
and just use JobManager.DoThis(); if the script in JobManager is static?

[rich adder]

You should only make specific things static

ie non-gameobjects etc

but yes when you make the class static you are using the class directly

static is also very useful for making a specific instance static

or just a method, or extension methods

[summer stump]

https://unity.huh.how/references/singletons

[quaint terrace]

thank you for helping, now i will read up on what a non-gameobject is and what an instance is

[rich adder]

non-gameobject meaning it can be anything just dont use for gameobject

MonoBehaviour basically

[quaint terrace]

oh i use MonoBehaviour. so if its a scriptable object it can be static?

[summer stump]

no

[rich adder]

no not that either

and it kinda works like a static anyway

[summer stump]

you probably don't want to make the class itself static most of the time. You'd want a static accessor (like the singleton pattern I linked above).

The cases where you DO want a static class are usually for "Extension Methods"
You don't want them to store state, you want to pass in data, let those extension methods transform it in some way, and return it. Like the c# Math class (not unity Mathf though, funny enough, which is a struct)

If you want to access state and variables, I would go with a singleton

but static class would be best like this:
public static class MyClass { }
It inherits from nothing

[rich adder]

or classes that just perform specific tasks

Debug.Log is a good example of static function but its not the class thats static

[quaint terrace]

ok i think i understand, https://paste.ofcode.org/XpZq67JrCbeiiUYwySxAwG this can be a Static because info goes in, and it just sends info out?

[summer stump]

While yes, I feel like this would make more sense as a singleton, that way you can modify them in the inspector

[rich adder]

note that if you use static you cannot use fields in them

they would also need to be static

though you could make all those floats just a struct

and make that field itself static

ie you cannot use non-static with static

[quaint terrace]

ok, so i learned something i dont currently have a use for, but its good to use for other things.

[summer stump]

Hahaha, that is fair. It's always good to learn!

[quaint terrace]

yea its fine. I was just on Codewars and it wouldnt accept my code so i looked up the solutions and everyone was using static and i couldnt understand why. my game doesnt or cant use static so thats probably why i never ran into it.

[foggy lark]

thanks!

[rich adder]

it fix ?

[foggy lark]

yessir

[rich adder]

nice!

[foggy lark]

fixed but is there a way for me to see them in different colors for each one of them?

like if is pink

[rich adder]

wait that doesnt seem configured fully though

ur missing quite the colors

[foggy lark]

i mean it works on unity

[rich adder]

but are you getting code completion ?

screenshot your VS editor fully

[rich adder]

yea not configured

this should say Assembly-CSharp

[foggy lark]

how do i configure them

[rich adder]

which one of the step u missed, did you do the part of selecting editor in unity?

[summer stump]

If you did all the steps in that guide, you may just need to click Regenerate Project Files in the External Tools menu

[foggy lark]

yes i did

[rich adder]

click Regen Project Files. make sure vs is closed, reopen script from unity

[foggy lark]

still no colors

[rich adder]

screenshot the Solution Explorer in VS

even though regen project files should do , might need to manually right click the solution and do Reload with Dependenicies

or w/e is called

[foggy lark]

umm where is solution explorer

[rich adder]

under View

or ctrl alt L

[summer stump]

In visual studio 😺

[rich adder]

yeah right click and rebuild

reload?

forgot which

[rich adder]

[ToolTip("HelloWorld")]
or you mean [Header("Hello World")]

[rich adder]

which one did you click

[foggy lark]

reload project

theres also install missing features

[rich adder]

did you not install the workload ?

[rich adder]

nope

you can either put it above or side by side with ,

[rich adder]

yeah that usually happens when you dont have the Unity Workload

[foggy lark]

oh mb when i first downloaded VS i was learing coding and wasnt planning on downloading unity, etc

[quaint terrace]

ty, i have always hated that VS opens when i accidently double click one of my scripts. I never knew i could just change this to Notepad++.

[foggy lark]

so this is gonna fix everything ?

[rich adder]

yeah it will fix it , make sure you have it

[rich adder]

oh lord..

[quaint terrace]

maybe on my next game I'll choose a "better" IDE.

[foggy lark]

thx @rich adder

[summer stump]

NO! 🫠 🤯 😭

[quaint terrace]

its beautiful

[summer stump]

Oh my god, it wasn't a horrific distasteful joke

[rich adder]

WHY

also thanks for burning my retinas

[quaint terrace]

I never had a teacher, im self taught. well ChatGPT has been helping me learn for 1 year next week.

[rich adder]

this is horrific

gpt has taught you wrong

why do you have a forach loop outside a function

and if its inside a function , why do you have local functions..

[summer stump]

Are you trying to upset us?

[quaint terrace]

its in clearSave, my tabs are wrong

[summer stump]

GPT is the worst

[rich adder]

please use a real IDE

[summer stump]

Notepad++ is not an IDE (and a configured IDE is required to get help here #📖┃code-of-conduct )

[polar acorn]

> ChatGPT
> Notepad
> Light Mode
> No indentation

[rich adder]

[quaint terrace]

wait My IDE is configured, it underlines errors and Auto completes code. dont scare me. also you sent me to community-conduct instead of read-me, which i read 5 times thinking i missed the IDE requirements.

[cobalt creek]

while i like np++ i use vscode more now

[twin ibex]

Hi ...

[summer stump]

Ah,yeah wrong link sorry. I just know the mods have told people to use a real IDE before when they use NP++ or risk being kicked

[twin ibex]

i have a problem

[cobalt creek]

what u problem, just say directly the problem

[quaint terrace]

same, i use NP++ =\ let hope yours is not as serious.

    }

}

Simple one

[summer stump]

Why use the Atan2?

https://docs.unity3d.com/ScriptReference/Quaternion.RotateTowards.html

[dire tartan]

hey if i want to check the velocity of an object is the only way to store it as a vector3?

or can i do it as a float

[rich adder]

you can store the .magnitude and store as float

[twin ibex]

Its like that

[summer stump]

But you aren't moving towards the player.... sooooooo IS it like that?

[twin ibex]

what ??

[summer stump]

Yeah, I guess the issue is not the rotation is it

Can you explain the issue better please?

[twin ibex]

its not an error

see

[summer stump]

Who said error?

[twin ibex]

no 1

i scaled the y by 2 to check if its going directly to the player

but its not

[summer stump]

The player is the circle?

[twin ibex]

yes

[summer stump]

Thennn... looks like the rotation IS the issue, and I think it's because Atan2 is used incorrectly

Try just using RotateTowards, right?

To clarify, your issue is that the triangle is pointing the wrong way?

It COULD also be the pivot point

[twin ibex]

what should i do

[summer stump]

Try just using rotatetowards

[twin ibex]

instad of what

oh

[twin ibex]

[cosmic mural]

i followed a tutorial for this sokoban top down 2d game

what is the purpose of the sqr magnitude?

if its afte a normalise is it not always just 1

[keen dew]

If there's no input it's 0

[golden obsidian]

sqrmagnitude is faster than magnitude (by removing the sqroot)

it's to check if there are any input

[eternal needle]

it doesnt make a whole lot of sense. Most beginner tutorials really are not good, and you are seeing that here.
Checking for a square magnitude of 0.5 means they are checking for a magnitude of sqrt(0.5) which is like 0.7071. This part has no specific reasoning because the magnitude will be 1 if it has input.

Even if they did not normalize it, they are using GetAxisRaw so the magnitude would be 1 at minimum if there was input

[sullen rock]

Hey! One of the tasks in my project is to "paint" over an area, I have that logic figured out. My issue is with figuring out how to check if the task is complete - my colelague wrote a piece of code that creates a 2D array of bools with the size of the target texture and checks when he paints each pixel, but that feels... weird, could anyone suggest a better path to take?

[night mural]

Ehh a 2d array of bools is probably fine? You could have a touched or untouched Set to which you add/remove values to keep track of which pixels have been painted, but I don't actually have a strong argument for why that's better. If you're worried about having to loop through all the pixels you could process them in a shader instead which would make that a non-issue

[sullen rock]

it doesnt actually loop through them - it uses a counter and textureCoords

[night mural]

yeah i was just thinking that didn't actually make sense

the reason you'd do this 'as they paint' is becaue that way you never have to loop through them

if you wanted to do the shader thing it would make more sense to not track anything as they paint and just process the whole image in a shader to look for pixels that are the 'unpainted' color or whatever

which would probably save you some memory and might be worth it on large images?

but adds a lot of technical complexity to what's going on

[night mural]

you might be able to get away with just the counter depending on how the painting works

but it's often nice to be able to have info about which pixels are unpainted, not just how many, both for debugging and so you can tell the player if you need to

[turbid robin]

I am making an AR app, is it possible to make a small menu that starts on the start of the app?

Menu with 4 button, each button take me to a different ar experience

Is it possible?

[languid spire]

what happens when your app starts is purely up to you. if you want a Menu make a menu.

[long furnace]

hello guys, i have an issue i will love it if u can help, i want to get a script with "FindObjectOfType" however its not very good for the performance so is it better to use "FindGameObjectWithTag" then use "GetComponent" to the refrenced GameObject or not? i hope u can help and thanks!

[tepid summit]

would that not do the same thing

[languid spire]

Better to do neither and have a direct reference

[north kiln]

@long furnace don't cross-post. I've removed your other questions

If you're wondering about their differences in performance, profile it.

[long furnace]

i wish to however its an instantiated Object and this is the best way i found

[long furnace]

what dose that mean

[languid spire]

look up 'dependency injection'

[long furnace]

ok thanks

[north kiln]

Posting to multiple channels at once

[long furnace]

lmao this is way to complicated, dont u know who is just faster? im not that advanced at coding .edit Thank you so much i found a way to set a refrence already

[north kiln]

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

[long furnace]

thank you too!

[rare basin]

what's the difference between doing,

public Action OnUnitDie;

and

public event Action OnUnitDie;

is it just for better IDE suggestions?

[modest dust]

An event can be only invoked from within the struct/class which declared/derived it

[timber tide]

event and delegates

[rare basin]

not sure if this is true

i can invoke that event in other classes just fine

[modest dust]

You can via calling a method, but not directly

[timber tide]

action is just a predefined delegate with a void return

[rare basin]

okay yea i cannot

I have noticed that without event keyword i cannot do some kind of missclick, like I cannot do

 LoadingManager.Instance.OnSceneLoaded = null;

but when i remove the event keywoard from public Action OnSceneLoaded

then i can do that just fine

possibly missclick and write = instead of +=

so i guess it's better to add that event keyword for more security?

[rich adder]

yes you cannot assign it from outside class that declared it with event keyword

only += and -=

[rare basin]

okay that's cool then, imma use it for more security

thanks

[timber tide]

yeah, I don't really use delegates outside of events, unless I'm binding methods to some identifier like through a dictionary.

I guess I do pass around interfaces sometimes with method implementations to substitute some of that functionality instead.

[rare basin]

yea that makes sense

[mortal bridge]

I wonder if there is a way you can modify c# scripts in unity to act more like how python does no ; no {}

How? Do you have a resource on that? never used one

[mortal bridge]

I actually dont like it

Im already used to it but I dont like it

[timber tide]

python so ugly though, why would you want to make an actual project with its syntax

[mortal bridge]

I like it better

[charred spoke]

https://docs.unity3d.com/Manual/roslyn-analyzers.html

Hero you go, but you are simply going to make your workflow much harder for zero gain

[timber tide]

single scripts ok, but trying to figure out what I was doing with it usually requires me writing double the comments ;)

[mortal bridge]

thanks man. my motto is work harder not smarter anyway

[teal viper]

I can already imagine a lot of pitfalls if they're gonna codegen to add semicolons and braces...😂

[charred spoke]

Have fun 🤣

I mean I wouldn’t touch this problem with a twenty foot stick

[teal viper]

I mean, it's basically writing your own language or compiler. I always consider it a task for the smartests in this world.

[gaunt ice]

you can turn any language to given syntax (grammar) by rewrite the parser and tokenizer and ast......but it literally becomes other language....

[mortal bridge]

Im actually dumb

[teal viper]

Maybe reconsider then

There are all kinds of programming languages, gotta accept that fact.

[mortal bridge]

no. My father said even if you are dumb if you are dedicated enough you can do anything

[teal viper]

Aight. Good luck then👍

[mortal bridge]

Thankz. I will share it here once Im done

maybe you guys wanna use

[teal viper]

If I'm gonna have to deal with python in C# I'm gonna shoot myself lol

[timber tide]

You can still use python in other ways like level gen and then parsing it in unity

I use it to quickly parse documents and export it over for some word game I was making

[gaunt ice]

btw you can use any languages you like if you know inter process communication
serialize everything to be byte stream then deserialize it

[timber tide]

yeah, python has a lot of libraries for AI and pathfinding which I can see being some utility for your project

[mortal bridge]

Thanks. I do not. Gotta learn

[timber tide]

I made pacman in pygame where I'd make the levels using wingdings in worddoc then importing it into my project

[teal viper]

Thankfully C# is neither.

[teal viper]

You'll still need the logic in C#. Or at least an interface that would interpret the messages from the python side. Not to mention that your game would consist of 2 processes.

am I funny?

[teal viper]

Not really

I just hope you know that braces and semicolons is not the only difference between C# and python

[mortal bridge]

I know. I used pyhton since I was 13 (Im 20 now)

[teal viper]

Did you use C# though?

[mortal bridge]

ehh mehh. not an expert

but I definietly used it. I have 6 completed projects in unity

as I said, i will share it here once Im done for free. something useful for community.

[foggy lark]

why i cant see Restart level on Events

why discord uploads only 1 photo

[charred spoke]

Because its private no one can see it

[foggy lark]

but the tutorial guy put it in private

[charred spoke]

The tutorial guy is wrong then

[foggy lark]

but it works on his video

[earnest atlas]

you cant call private function

outside of class

[charred spoke]

Then it probably got changed to public at some point

Watch the tutorial again

[earnest atlas]

The sneaky private switcheru

[foggy lark]

switched to public still cant see it

[charred spoke]

I think somewhere digiholic’s counter is going up by one

[earnest atlas]

Did u save the script?

[foggy lark]

class is also public btw

yea

[earnest atlas]

Where are you calling the function?

full screenshot

[foggy lark]

ahhh

start is private

[earnest atlas]

it doesnt matter

[foggy lark]

but its in the start

[earnest atlas]

what is in the start

[foggy lark]

restartlevel

[earnest atlas]

why the function is inside start?

[foggy lark]

again tutorial guy put it there

[earnest atlas]

its not in the start in your screenshot

[foggy lark]

oh its not yes

mb

forget that then

[charred spoke]

do you have compile errors ?

[foggy lark]

i do not

i found the problem

[foggy lark]

its not in the start that was the problem

[earnest atlas]

I know it wasnt the start

[foggy lark]

umm still cant see it tho

[earnest atlas]

rip

[foggy lark]

ill just do other ways of restarting the level ig

[earnest atlas]

where are you trying to call restart function

[foggy lark]

in death animation

[earnest atlas]

I mean object

[foggy lark]

you mean where is the script in ?

[earnest atlas]

yteah

[foggy lark]

Player

[queen adder]

Hello

[foggy lark]

hi

[earnest atlas]

This thing

Post it

[foggy lark]

yea its in the player

[earnest atlas]

ENTIRE THING

[foggy lark]

THERES A LOT OF TABS

[earnest atlas]

I mean entire thing where script is seen

[earnest atlas]

where you trying to call restart level

[foggy lark]

in death animation i already told u

[earnest atlas]

Where is that death animation

[earnest atlas]

im pretty sure you cant call function from scripts in animator

[foggy lark]

the thing is other scripts shows up

[hexed terrace]

Is there actually an animation?

[foggy lark]

yes

[hexed terrace]

an odd way to do it tbh, but regardless. When following a tutorial, if it works for them and not you... you've done something wrong/ missed something, go back and rewatch

[foggy lark]

i can see other scripts

[foggy lark]

yea ik the guy in the video also said ' you can just make count down'

[hexed terrace]

so, you can't see your PlayerLife script where this method is you want to call, in this dropdown?

[foggy lark]

yes

[hexed terrace]

re-read the list, closelierly

[foggy lark]

it should be RestartLevel there

[hexed terrace]

no it shoudlnt

[languid spire]

no

[hexed terrace]

RestartLevel is a method, not a script

[rare basin]

well technically you can, in inner class

[hexed terrace]

RestartLevel is IN the PlayerLife class

[earnest atlas]

he was trying to call it completly outside

[foggy lark]

oh

OH yes

[hexed terrace]

perhaps, it would be a good idea to learn the very basics of C# ... what a class is, method, the setup of them etc

[foggy lark]

video is 2 years ago older verison of unity maybe thats why?, cuz on video it instantly pops up

[rare basin]

it's hard to help you

since you dont understand the given help

[hexed terrace]

dunno, without seeing the video. But if it differs, this highlights why you should do a tutorial on the same version

[foggy lark]

maybe you're right and i need more classes about c# after all

[mortal bridge]

what tutorial

tutorial guys suck at writing good codes

dont watch beginner tutorials learning c#

they suck

[hexed terrace]

this is a code channel, delete and ask in #📲┃ui-ux

[mortal bridge]

go to learn unity

[dusk minnow]

alr

[rare basin]

why everyone ask everything in code channels 🤔

[hexed terrace]

laziness, stupidity, lack of care

[mortal bridge]

https://youtu.be/M1StS3t8cD4

[worthy merlin]

Watching after i take a tutorial lmao

[languid spire]

add wilful ignorance and you are describing 90% of the people asking questions

[mortal bridge]

you can watch tutorials on specific topics where you are stuck but for beginners and for learning from scratch they succ

[worthy merlin]

Would a steo by step beginner tutorial be the same? Such as https://youtu.be/XtQMytORBmM?si=Uvo8tOQT5D9_qH8q

[mortal bridge]

I hate them so much. they dont teach you fishng they give you fish butthat fish is only one specie. and you cant change the fish later when you try from svratch let alone being able to fish

[mortal bridge]

this one is good

[rare basin]

most of the unity "TUTORIALS" just teach you bad code

with bad architecture

that is non extensible

[worthy merlin]

Yeah cause I was like. This so for has helped me the best

[rare basin]

and hard to add new things

not-designer friendly

and just bad and non-dev friendly to work with with plenty of bad practices

does it work? it does, but is it good? most of them are terrible

[mortal bridge]

my man. If you feel you are learning you are in right path. If you feeel just copy paste and dont know why that guy does that writes that then wrong path

brain shouldnt be on autopilot

[worthy merlin]

True

[mortal bridge]

Gm is a great guy. since he studied the art of learning hence can make a great tutorial

[worthy merlin]

I just wish someone would create structure. Do these kinda tutorials and indicate where the user can improve it and send them to a doc all about it if they want to learn those things

[rare basin]

code architecture is a thing you need to learn yourself mostly

based on many projects done

many trials and errors

many abandonded projects due to bad architecture

then you improve on next project etc

[worthy merlin]

Even going through gms course. I'd see little things like making a boolean return method == true in an if instead of just leaving the method in paraethesis. Shorter and also works

[mortal bridge]

i still do that

amd i dont use += *= etc...

preferences

[worthy merlin]

Will say C# is gonna teach me to use ; in javascript now

I always ignore it

[mortal bridge]

vs underlines it in red not hard to miss

[worthy merlin]

Exactly

[mortal bridge]

just hope that all you write doesnt change colours😂

[buoyant knot]

i used to hate ;
But then I realized using // to make multiline code is so much more obnoxious

i have embraced the semicolon

[queen adder]

Was the GameObject.SetActive is delayed for end of frame or immediate?

[swift crag]

It occurs immediately.

[cosmic dagger]

I thought it was at the end of the frame . . .

[hazy ember]

Hello, I’m doing a code where inputs are in update() and physics calculations are in fixedUpdate().
A cooldown mechanic is being added, should it count the elapsed time in update() or fixedUpdate()?

Like, should it go along with the inputs or in sync with the physics?

[wintry quarry]

What is the cool down for

[rare basin]

it depends

[swift crag]

I would keep cooldown timers together with whatever they're a cooldown timer for.

[hazy ember]

A dash

[rare basin]

Destroy() is at the next frame

SetActive() is immediately

[wintry quarry]

I'd probably do it in FixedUpdate

[hazy ember]

Thank you, just realised it’s better that way too because of how inconsistent it’d be with the FPS 😅

[swift crag]

That is not a problem.

given that you're already handling user inputs in Update (as you ought to be)

I'd probably lean towards handling all cooldowns in Update just for consistency's sake -- especially if I also check the cooldown timer in Update

[hazy ember]

Yeah I am, when I put the CD calculations in update() it feels out of sync with the game’s physics at low fps though

[cosmic dagger]

Yes, Destroy is at the end of the frame, but I thought the activation/deactivation also occurs at the end. I know the flag will set the active state immediately . . .

[swift crag]

well now I'm not sure :p

[rare basin]

it's on the next frame actually, not at the end of the frame

[swift crag]

i'll have to check now

[rare basin]

SetActive() is 100% immedtiately

Destroy() is next frame

[dense cypress]

how can I get a variable from one game object and put it into another

[languid spire]

game objects dont have many variables, do you mean components on game objects?

[dense cypress]

yes

actually it's a variable in a component in a child

[languid spire]

gameobject1.GetComponent<A>().variable = gameObject2.GetComponent<B>().variable
gameobject1.GetComponent<A>().variable = gameObject2.transform.GetChild(x).GetComponent<B>().variable

[mortal bridge]

thats good

[turbid robin]

how can i make it? is there a tutorial?

[languid spire]

!learn

i am followung the guide for ar there, but i dont like ti that much tbh

isnt ther another guide?

[languid spire]

yt is full of them, mostly crap

[dense cypress]

I'm not sure I understand what I'm doing so I'll give more context: script (PlayerMovement) needs to rotate the object it's attached to (Player) by the amount of the variable yRotation which is created and valued in a script (PlayerCamera) in Player's child (PlayerCamera)

[mortal bridge]

thats pretty ez man

[turbid robin]

well, i just think that i need to understand scene manager and how to use button, also for that youtube is bad?

[dense cypress]

well from what I'm doing it's getting the variable as 0

[mortal bridge]

send cods

[dense cypress]

https://gdl.space/ugekujuveb.cs

[languid spire]

yes, because the problem is you will not have the knowledge to know if they are bad or not

[turbid robin]

were do i have to check in unity learn?

[languid spire]

would you like me to take the lessons for you, save you all the effort

[mortal bridge]

they wont load myman

stuck here for minutes

damn

[mortal bridge]

go scrrenshot

[turbid robin]

if you dont want to respond is not my problem, just dont respond 🤷‍♂️

[mortal bridge]

bro hes just trying to make you find things your own chill. google js way better than individyals about specific topics

[turbid robin]

you say that youtube is bad and i need to use unity learn, i ask "were on unity learn?" and you dont tell me. how am i supposted to know erer things are on a website that i almost never used?

[mortal bridge]

what are those comments??? is it fron chat lgbt

[dense cypress]

no

[turbid robin]

google find me youtube

[dense cypress]

I tried to do it myself but some of the code was from videos

so I tried to understand what it does

[mortal bridge]

hello i wanna make a game about ...x where you .... and i also wanna make enemies ..... and j wanna make them ...... too do you have guides on that? bro ifur gona make something special better make it yourself

[turbid robin]

make myself something i dont how to make because i dont have aguide

[mortal bridge]

omg

its the easiest part

i can fjnd many right now

[turbid robin]

you see something that isnt youtube?

[rare basin]

that just confirmed what i said

[mortal bridge]

@dense cypress ill take a look in a sec im not on pc those codes i cant read my phone is bugged cant zoom discord images

[dense cypress]

ok

[languid spire]

no it didn't, you said "next frame"

[rare basin]

well, after the entire Update loop

can be interpreted in both ways

either end of current frame or start of the next noe

[languid spire]

but there is still a lot of the current frame left at that point

[mortal bridge]

@turbid robin 100 bucks. i do what you want

[rare basin]

okay yea fair enough

[turbid robin]

🤣

[rare basin]

but what if i called Destroy() not in the Update

if it's called in Update then it will indeed happen after the current Update loop

but if it's called somewhere else, let's say in OnTriggerEnter

then it will be destroyed after current frame

[cosmic dagger]

trigger events are processed during the physics loop which occurs before Update . . .

[rare basin]

not related

[mortal bridge]

man

so I see y rotation

but i only see y rotation

[dense cypress]

what

[mortal bridge]

its kind of a riddle. can you find it out

[dense cypress]

the playermovement only wants to rotate on y if that's what you mean

because I dont what it to fall over

[mortal bridge]

you need to change something in update

or add

[dense cypress]

which script

[mortal bridge]

playerm....

[dense cypress]

wait do I put ``` yRotation = camera.GetComponent<PlayerCamera>().yRotation;

yeah I did it works now thanks

[mortal bridge]

why did you put it

[dense cypress]

update

before the part where it rotates

[mortal bridge]

how did you know you had to use it 🧐

[languid spire]

actually you should put the GetComponent part in Start and the yRotation=yRotation part in Update

[dense cypress]

It occured to me after you said to put something in update

what does yRotation=yRotation do

[mortal bridge]

I hope your not asking chatlgbt

[dense cypress]

I didn't I promise

Legit

fr

no 🧢

[mortal bridge]

thats too complicated for a beginner but anyawy 🤨

[dense cypress]

is it?

[languid spire]

but you are not really understanding any of this are you

[dense cypress]

I am sort of idk

but I actually didn't use chatgpt

[mortal bridge]

hmm good legit

[dense cypress]

chatgpt didn't deserve such slander

[mortal bridge]

very good

If you keep working like this for 10 years you will be rich dont forget

[dense cypress]

wait how do I increase the gravity on a rigidbody

[mortal bridge]

very ez

get pshyics

[dense cypress]

just as default

[verbal dome]

2d or 3d?

[dense cypress]

3d

[verbal dome]

One rigidbody or all?

[mortal bridge]

Yesterday I actually wrote codes for that might as well share ithere

[dense cypress]

I only have one rn but probably everything

[verbal dome]

So search for how to change gravity

[verbal dome]

If it was 2d you can change it per-rigidbody, but 3d uses a global value

[mortal bridge]

this is a hint

do the rest yourself

you can actually optimize by Physics.gravity *= changeGravity but thats not how I do it so

[spiral narwhal]

If I have a child of a UI object. How do I get its actual position in the world, not the one relative to its parent? Would that be anchoredPosition?

[mortal bridge]

no

[spiral narwhal]

Gonna elaborate?

[low path]

https://stackoverflow.com/questions/56869568/how-can-i-get-screen-position-of-a-ui-element

[teal viper]

transform.position should be it.

[spiral narwhal]

And if it has a rectTransform, transform uses that rectTransform?

Because it's a UI item

[mortal bridge]

yea

[teal viper]

RectTransform extends Transform, so yes.

[mortal bridge]

I have a very good opinion. we add google to this server and make googling for 1 minute mandatory before asking quetsions

[spiral narwhal]

Just like not responding with Noto a How? question should be mandatory?

[mortal bridge]

I responded to Would that be anchoredPosition

[spiral narwhal]

Yes, very helpful indeed

[mortal bridge]

Idk man. maybe try copy pasting your question next time

[mild mortar]

Think I'm being stupid here.
I'm trying to have the health text animated so that if the character takes 5 damage, the text goes from say 100 - 99 - 98... 95

With my current code though, I am giving 5 damage to the player, but the damage received seems to be like 5.something as the health text ends up as 94.9672 or something like that.

Any ideas?

public void ReceiveDamage(float damage)
    {
        StartCoroutine(ReduceHealth(damage));
    }

    private void UpdateText()
    {
        healthText.text = currentHealth.ToString() + "%";
    }

    private IEnumerator ReduceHealth (float damage)
    {
        float damagePerSecond = damage / smoothDuration;
        float timeElapsed = 0f;

        while (timeElapsed < smoothDuration)
        {
            float currentDamage = damagePerSecond * Time.deltaTime;
            currentHealth -= currentDamage;          
            timeElapsed += Time.deltaTime;
        
            // Update health bar where max health is equal to 0.5 fill amount
            healthBar.fillAmount = (currentHealth / maxHealth) / 2;
            if (currentHealth / maxHealth * 100 <= 40)
            {
                healthBar.color = criticalColour;
            }

            UpdateText();

            if (currentHealth <= 0)
            {
                currentHealth = 0;
                UpdateText();
                // Die
            }
            yield return null;
        }
    }

[mortal bridge]

wohoho the great chinese wall

[languid spire]

you can, you need to create scope for each case

[mortal bridge]

so what happens when you divide and multiply and do all sorts of things to some numbers? would they likely be int?

[languid spire]

same as always { }

[mortal bridge]

@mild mortartry rounding some of them

I tried. works

[rain heart]

can someone help me with this?

[rain heart]

i dont know why there are lines between my tiles

[mortal bridge]

hmm I wonder why

those lines seem familiar to me

[mild mortar]

Sorry for the late reply, I was trying something

Where would you suggest exactly? I've tried just rounding hurrentHealth after applying the damage, but instead of losing 5%, it loses 3% or so

[teal viper]

Coroutines are not precise to the millisecond, as they can only run once per frame at a very specific time. Then there are floating point errors and weird math and it all adds up to an imprecise value.

[rain heart]

X_X

[mild mortar]

Hmmm
I was basically following along to a youtube tutorial for this which is why I've been more confused as to how it worked on the video but not for me

[teal viper]

Either use a Lerp or a MoveTowards to transition a value smoothly and precisely.

[teal viper]

This code would produce different results at different frame rate, so perhaps it just happened to work for them in their environment.

Or you missed something in the tutorial 🤷‍♂️

[mortal bridge]

h1mmmm

[mild mortar]

Ah okay.

The tutorial is only a few minutes long and i've checked multiple times so I don't think I missed anything 🤔

I'll have a look at where to use Lerp then

[mortal bridge]

weird

5 to 3?

I may be being stupid too rn

[mild mortar]

Essentially yeah, I applied what should be 5 damage, but the health text showed it as 97%

[mortal bridge]

oh

you only rounded health?

I think I see now

do you want my vesrion of the code?

It work on my machine 😄

[mild mortar]

Sure, would appreciate being able to see a different version 😂

Thanks

[mortal bridge]

pff my ctrl doesnt work

gotta write by hand

Just what you didn't need lol, always the case 🤷‍♀️

so can someone help me with this please? i couldnt find anything

[halcyon summit]

Anyone have any experience with changing the colour of shared font materials in code? All my searching so far suggests I should use Material newFontMaterial = textMeshPro.fontSharedMaterial; but newFontMaterial.color = newColour doesn't seem to make any changes.

are your sprites set to point filter, and no compression

they look blurry

and are the sprites on a sprite atlas, because i assume they are not

and is the actual sprite brought in as 16x16

i assume the answer to all these questions is no

[rain heart]

yes the point filter fixed it thank you

for reference, when using pixel art, you always need to set point filter, no compression

god Im really stupit today

[eager spindle]

good evening
I am using unity 2022.3.8f1, am following a tutorial that uses IMGUI(for debugging purposes). the IMGUI buttons show up in the built version but not in the editor; is there something I need to enable for IMGUI buttons to show up in the editor?

[mild mortar]

Seems to be working fine there 🙂

The actually current health still seems to have that thing of being like 89.8216 etc
But the text displays it as 90%. Just gonna hope and assume it's minor enough that there isn't a problem caused from it

[swift crag]

Are the buttons blank?

Or are they completely missing?

[eager spindle]

they are completely missing

[swift crag]

Maybe an exception is being thrown

[mortal bridge]

how? I think I wrote roundtoInt

[swift crag]

Check the player log file.

[mortal bridge]

im a bit high today

[eager spindle]

editor with gizmos on

[swift crag]

oh, I read that backwards!

in the built game, not in the editor

[eager spindle]

build

[mortal bridge]

oh yeah

I see

[swift crag]

note that you don't need Gizmos on to see IMGUI graphics

That's the problem.

Your game view is zoomed in.

[eager spindle]

ah

I didnt see it was zoomed in ty

[swift crag]

np!

[swift crag]

I had a problem on my Steam Deck where the default font just...didn't work

so I had to set the default gui style's fonts on startup

[mild mortar]

Yeah the text is rounded, I just meant the behind the scenes actual health isn't rounded, so hoping when calculations and stuff come in, that the player isn't really affected from a build up of those trailing digits

[mortal bridge]

it can accumulte

[night sparrow]

is there any way of checking if ray Hit the Object head inside the Player object like the Health component but detect if the Ray hits the Head object instead

    void Fire()
    {
        recoiling = true;
        recovering = false;

        Ray ray = new Ray(camera.transform.position, camera.transform.forward);
        RaycastHit hit;

        if (Physics.Raycast(ray.origin, ray.direction, out hit, 100f))
        {
            Health targetHealth = hit.transform.gameObject.GetComponent<Health>();
            bool isHeadShot = false;

            if (targetHealth != null)
            {

                Debug.Log(hit.transform.name);

                string vfxName = isHeadShot ? hitGoldVFX.name : hitRedVFX.name;
                PhotonNetwork.Instantiate(vfxName, hit.point, Quaternion.identity);

                int damageValue = isHeadShot ? headShotDamage : damage;
                Debug.Log("Damage to be done " + damageValue.ToString());
                hit.transform.gameObject.GetComponent<PhotonView>().RPC("TakeDamage", RpcTarget.All, damageValue);
            }
            else
            {
                PhotonNetwork.Instantiate(hitWhiteVFX.name, hit.point, Quaternion.identity);
            }
        }
    }```

[swift crag]

RaycastHit includes a collider property

This tells you the exact collider that you hit.

transform can point at either the collider's Transform (if there is no parent Rigidbody) or at the Rigidbody's Transform (if there is one)

So, you can do something like this

if (hit.collider.TryGetComponent(out Hitbox hitbox)) {
  damage *= hitbox.damageMultiplier;
}

[mild mortar]

Yeah, so I guess it still has the same kind of problem then

[swift crag]

create a Hitbox component that lives on the same object as the collider

[mortal bridge]

currentHealth = Mathf.Round(currentHealth * 100) / 100 (I think its is 100 yes? but I THought of this before but it may make it less smooth

so I didnt

[swift crag]

do you want to show a percentage?

[night sparrow]

So i can do like Debug.Log(hit.collider.name); To see what its hitting and should say the Head if head?

[swift crag]

$"{playerHealth:P0}"

This is string interpolation

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/tokens/interpolated

[mortal bridge]

his problem is

please help him

[swift crag]

$"{0.123:P0}" will produce "12%"

$"{0.123:P1}" will produce "12.3%"

etc.

the general form is {expression:formatinfo}

[mild mortar]

Yeah, I followed along to a tutorial and just want the health to display correctly and also smoothly decrease on the text when damage is taken

[swift crag]

P0 means "percentage with 0 decimal places"

[mortal bridge]

the code above should fix it but it may not make it as smoothly

[swift crag]

That'll display the health percentage properly.

[mortal bridge]

I m not very experienced in this stuff

it may accumlate without it

[swift crag]

To make it change smoothly, you'll want to track the displayed health separately from the actual health

Assuming these are both percentages already, this will change the displayed health by at most 20% per second:

displayedHealth = Mathf.MoveTowards(displayedHealth, health, Time.deltaTime * 0.2f);

You can then use string interpolation to turn displayedHealth into a nice percentage

[mild mortar]

I'll try that then quickly, thanks

[swift crag]

healthText.text = $"{displayedHealth:P0}";

I believe this will round to the nearest hundredth

rather than rounding up or rounding down

[mortal bridge]

damn yeah this makes sense

[swift crag]

so 0.3% health will become 0%

[mortal bridge]

If my mind was in its place I'd definietly recommendthis 100%%

[covert glade]

hello im tryna make a code that destroys the player when the player collides with a spike

but instead it destroys the parent and its childs

can i make it only destroy the parent?

[swift crag]

you could unparent the camera first

I would suggest just making the camera follow the player

[mortal bridge]

@swift cragyou seem experienced in this stuff. do you mind telling me why my code kinda works but not as smooth? I actually know why but I cant get to fix it

[swift crag]

Cinemachine would be ideal.

[covert glade]

whats that?

[mild mortar]

So in the case of my code here, how would you say to implement this best?

public void ReceiveDamage(float damage)
    {
        StartCoroutine(ReduceHealth(damage));
    }

    private void UpdateText()
    {
        healthText.text = currentHealth.ToString() + "%";
    }

    private IEnumerator ReduceHealth (float damage)
    {
        float damagePerSecond = damage / smoothDuration;
        float timeElapsed = 0f;

        while (timeElapsed < smoothDuration)
        {
            float currentDamage = damagePerSecond * Time.deltaTime;
            currentHealth -= currentDamage;          
            timeElapsed += Time.deltaTime;
        
            // Update health bar where max health is equal to 0.5 fill amount
            healthBar.fillAmount = (currentHealth / maxHealth) / 2;
            if (currentHealth / maxHealth * 100 <= 40)
            {
                healthBar.color = criticalColour;
            }

            UpdateText();

            if (currentHealth <= 0)
            {
                currentHealth = 0;
                UpdateText();
                // Die
            }
            yield return null;
        }
    }

[swift crag]

It's a package provided by Unity. You create virtual cameras that control where the real camera goes.

If you don't want to jump into that immediately, you could also just use a Parent Constraint on the camera

the Parent Constraint makes an object act like it's parented -- it moves and rotates as its parent moves and rotates

[covert glade]

what is that aswell ;-;

oh

u said it already

[mortal bridge]

@mild mortarIs this what you want?

[swift crag]

it's a component!

[covert glade]

didnt see it

[swift crag]

Add a constraint source, drag the player into it, position the camera how you want it, and hit Activate

[mild mortar]

In one sense yes, wouldn't want the player to be alive because they 0.3 health

[swift crag]

imagine this says "Player" :p

[swift crag]

well, 0.3% is still more than 0% (:

[mortal bridge]

damn not fair man

[swift crag]

Mostly dead is slightly alive!

[mild mortar]

Oh my bad I wrote that poorly

I meant in terms of the health text

Wouldnt want it to say 0 but still be alive I meant

[swift crag]

Ah, actually, it looks like it just truncates the number.

So 0.9% becomes 0%

[burnt vapor]

Then use ceil and use that result

Rather than regular rounding

[swift crag]

oh, no, I was right all along (:

When precision specifier controls the number of fractional digits in the result string, the result string reflects a number that is rounded to a representable result nearest to the infinitely precise result. If there are two equally near representable results:

[burnt vapor]

https://learn.microsoft.com/en-us/dotnet/api/system.math.ceiling?view=net-8.0

[swift crag]

You'll still need to adjust the number, then

[buoyant knot]

it generally makes more sense for HP to be an int, not a float

[swift crag]

this is a percentage

[burnt vapor]

(use ceil and cast to integer)

[buoyant knot]

it is easier to deal with discrete rounding errors than to deal with float nonsense

[swift crag]

float correctedHealthPercentage = Mathf.Ceil(healthPercentage * 100) / 100;
healthText.text = $"{correctedHealthPercentage:P0}";

[buoyant knot]

then cast the int to a float for display purposes, but the underlying actual value is an int

[swift crag]

like so

[verbal dome]

Then you can have nothing that deals less than 1 damage

At a time

[mortal bridge]

Is it only me who thought about clamp?

[buoyant knot]

and now you can deal 1e-6 dmg instead

[verbal dome]

It might fit fot some games tho

[burnt vapor]

Yes, because how is that related

[swift crag]

Using a float means that your minimum damage amount is now...wishy-washy

integers have a pleasant concreteness to them

you know it'll always behave properly

[buoyant knot]

yeah, you need the very fixed nature lf ints to avoid float weirdness

[burnt vapor]

I can't remember the last time I saw a game handle health as a floating point number

[swift crag]

of course, continuous damage is a lot more annoying to do with ints

you have to chunk it up

[mild mortar]

Yep, that's what I thought. But the tutorial I followed along to put it into floats for some reason so I just went with it 🤷‍♀️

[covert glade]

how to reference a gameobject like the player in code?

[swift crag]

and slight differences suddenly get really important

[buoyant knot]

i would rather use a big int for resolution, than use a float

[verbal dome]

Thats a decent option

[burnt vapor]

It's fine, just use that ceiling method I linked if you worry about displaying 0 health, and it's fine. Handling health as a float is fine but it's weird displaying it as one

[buoyant knot]

if 100 HP is not enough, try 10,000,000 HP. And use properties to display sensical numbers

[mortal bridge]

guys what about clamp so we may get rid of accumulation problems??

[buoyant knot]

if numbers can get big, you should use a long for HP

[burnt vapor]

Do you know what clamping is?

[swift crag]

clamp confines a value into a range. it doesn't help you at all with rounding

[mortal bridge]

yes

[verbal dome]

You mean Max?

[burnt vapor]

I doubt it

[summer stump]

https://unity.huh.how/references

[mortal bridge]

yea

[buoyant knot]

pokemon gets into issues all the time because they used SHORTS for HP. One of the dumbfuckiest programming mistakes to make in 2022

[long furnace]

just do "public GameObject Player;

[mortal bridge]

If health goes below 0 due to small value it may accumulate

[buoyant knot]

it can overflow

it can underflow

don’t use shorts for HP

[swift crag]

Floats fail much more gradually than ints

they behave similarly for small numbers and for large numbers, which is a nice property

[burnt vapor]

I wonder what the point of using such a small value would be in the first place when you develop a game with no networking

You just shoot yourself in the foot with it

[buoyant knot]

idfk. there is literally no reason to actively choose to make this small number a short vs long

or even a regular int

[swift crag]

the relative precision around 1 and 1e10 is the same; integers' relative precision goes up until you hit the maximum integer, and then they abruptly fail

[mortal bridge]

yes

thats right

not my point tho

[buoyant knot]

pokemon has a lot of performance issues, but using shorts vs longs for HP is not doing shit, capn

[buoyant knot]

float HP only makes sense for the cookie clicker hero clicker things

[burnt vapor]

I don't think anybody knows your point considering you are suggesting a totally unrelated method

[buoyant knot]

where you are storing values actually on the order of 10^200

[swift crag]

floats are great when everything scales up together

multiplying 1 by 0.1 is roughly the same as multiplying 1e20 by 1e19

but adding 1 and 0.1 is nothing like adding 1e20 and 0.1, and that's where floats are horrible

integers have consistent precision when adding a fixed value

[mortal bridge]

something like
currentHealth = Mathf.Round(Mathf.Clamp(currentHealth, 0, maxHealth));

[swift crag]

i would just not allowe currentHealth to ever go negative

[shell sorrel]

its common to clamp it, but why would you round

if you want whole numbers use ints

[swift crag]

by not letting your actual health go negative

i think the idea is that this is being displayed as as percentage

[shell sorrel]

i keep how things are displayed and how its in data seperated

[swift crag]

but you should just be doing healthPercentage = ((float) health) / maxHealth and then going from there

[swift crag]

you definitely shouldn't remember the rounded value!

[shell sorrel]

and always found health as int is always better

no ambiguous situations

but you can show it to the user anyway you want

[timber tide]

I use floats usually just to keep them contained in a single dictionary

[mortal bridge]

so what do you guys think of this? iif hp s less than 0 it will be set to 0. If it’s more than max it will be set to maxHealth

[timber tide]

as far as grouping stats goes

[mortal bridge]

no accumulation problems

[buoyant knot]

use a property with custom setter for HP

[swift crag]

yes, it's reasonable to clamp your actual health value

[verbal dome]

That doesnt solve accumulation problems

[swift crag]

but this rounded value shouldn't even be remembered

[tough lagoon]

Just weighing in on what I think was the original question, and that this is the right answer to me.

For some of my games, it's helpful to have stats as ints but health as floats. They are procedural self playing rpgs, and calculating micro damage matters. But most games, int for health makes sense.

[swift crag]

the real big-brain scheme is to not even have a difference between stats and health (:

[tough lagoon]

Could use a decimal or something else sure, but in practicality it isn't much if a problem

[buoyant knot]

your HP should be an int, and have a custom setter that automatically makes sure it can’t be negative

[tough lagoon]

Not necessarily, there are lots of times where you may want incremental damage over time that isn't an absolute 1 or 0 though.

[buoyant knot]

my HP is a ClampedReactiveValue<int>, where this is a proxy that automatically clamps an incoming value, and invokes a method when it changes

[buoyant knot]

use a big int

with property to get a simpler display value

[tough lagoon]

No, I think it's just inventing work tbh

[buoyant knot]

it is not

using a float for HP invents work in tracking down bugs from float imprecision

don’t deal with any of that shit. use an int backing field

[tough lagoon]

No, that's not a problem in 99.9% of games in practicality

[buoyant knot]

a property takes extremely little effort to make. it is a core part of C#

there is no excuse to not use properties

and store a robust value that won’t cause headaches

[tough lagoon]

That has nothing to do with using an int vs float

[buoyant knot]

your point was that making a property invents work

[tough lagoon]

That's just a process to it

[buoyant knot]

it does not invent work. it is a part of using the language. the only situation where you want to store HP as a float is cookie clicker/hero clicker, where HP goes between 1 and 10^200

[tough lagoon]

Well, I support you doing what you want. But this to me sounds like trying to solve an edge case you won't see by inventing work to avoid a problem that isn't going to happen in practice.

[buoyant knot]

there is a reason every JRPG in the world uses discrete integer HP

because they do not want to deal with float nonsense

if you do not see the value, then do whatever. you have been warned

[tough lagoon]

Yes, I don't. 🙂

[buoyant knot]

btw float HP struggles to be 0% and 100%. because floats suck at ==

[tough lagoon]

There are of course times where you need to change to meet an objective. But worrying about the edges of a float on a health bar for a game is (in my opinion not a problem in practice) but it is your call or whomever is making whichever

Using an int is fine, using a float is fine, using properties to pretend an int isn't an int, use it if you need it.

[buoyant knot]

you only need to turn an int to a float for display bars or displaying percentages

[tough lagoon]

I'm just back scrolling to make sure a question wasn't overlooked from folks

[buoyant knot]

with int HP, all game logic should use integer HP and integer dmg

[tough lagoon]

I definitely agree on doing good clamping in general when you need it - it's just good practice

[clear laurel]

Hi #archived-code-general are in an argument and not looking at my message so thought I'd try here before asking in advanced

I'm working on a custom package for my essential starter tools, the sorts that I can use in every project, my problem is that one of these tools needs to be customized per project and that's not easy if it's sitting in the packages directory, is there a way I can have the package place a folder with these specific assets into the assets directory? Similar to installing an exported package maybe?

[mortal bridge]

heyman

actually

you can take a look at one question

if you want to

i can reference

[tough lagoon]

It's pretty common to have a scriptable object or other configuration file that you generate in Assets. You could write something to do it. But I think it's really only meant to include config files.

But you can write some tooling for the package that you can right click to generate a thing that uses the package ?

[mortal bridge]

@mild mortarhey buddy did you solve the issue?

[tough lagoon]

Without knowing more an interface sounds like a good approach as well

[mild mortar]

I haven't actually sadly, still stuck on working it out 😅
Probably doesn't help I've been coding for hours straight so I'm actually braindead and barely functioning now

[clear laurel]

so my current jerry-rigged solution is using Assetbase to copy some of the scripts into an assets folder then using FileUtils to delete the ones remaining in packages but this doesn't seem a very good solution, I ran into the problem after I added an editor to the class and in the project I had it imported it broke due to namespaces and because the editor was still in the packages directory

[mortal bridge]

so@tough lagoon you said you didnt wanted overlooked questins you can take a look at this

[mortal bridge]

did you try what the fox guy told you?

[mortal bridge]

this one

[mild mortar]

I haven't tried that yet, I'm just caught up on an appointment phonecall atm, so will be looking to try that soon

[opaque fox]

Would anyone know how to get an AI to move in a straight line once it spots the player without changing direction? Right now I have it set to chasing the player normally, any ideas on how to get it to only charge in a straight line?

I'm trying to use bools to get it to target the first known position, but I can't get it to work

[polar acorn]

Only set the destination once. If it's already targetting a spot, don't call SetDestination again. Only call that line whenever the enemy starts looking at the player, then set a boolean to prevent it from running again until it reaches its destination

[opaque fox]

gotcha gotcha

[noble summit]

what is the different between velocity and force

[swift crag]

velocity is the direction you are moving and how fast you're moving

force is the direction you are pushing and how hard you're pushing

Force, applied over time, steadily increases your velocity

Gravity is a common source of force.

[verbal dome]

AddForce really just adds to the velocity

[swift crag]

A force of 10 newtons accelerates a 1kg object by 10m/s per second

or 10 m/s^2 !

[swift crag]

although, you usually don't express gravity as a force, directly

Gravity's force is proportional to your mass

So you can just express gravity as an acceleration, directly

if you double your mass you double the force, and it's a wash

rigidbody.AddForce(-9.8f * Vector3.down, ForceMode.Acceleration);

[brazen canyon]

Guys help
How to uniformly scale a GO ??

[polar acorn]

transform.localScale *= someSingleValue

[gaunt ice]

by scaling it with same values across three different axes

[brazen canyon]

I'm having this trouble

My gun looks so weird

[swift crag]

I presume it's parented to something that is not uniformly scaled.

If a parent is non-uniformly scaled, then children will get skewed as they rotate

[brazen canyon]

YES
That's what they said

[swift crag]

In this case, I would suggest rearranging your player slightly

• Player
  • Visual <-- non-uniformly scaled; has the mesh renderer
  • Camera
  • Gun Holder
    • Gun

(or just parent the gun to the camera)

This way, the weapon is not parented to a non-uniformly scaled object, and everything's happy

[swift crag]

It doesn't matter if you are non-uniformly scaled: it's about your parents

[frigid sequoia]

Have you tried changing the camera fov?

[swift crag]

that thing looks scrungled

to use the technical term

[polar acorn]

not really related

[swift crag]

A super-wide FOV would definitely cause its own distortion

And without that scene view, I'd be tempted to say it is just because the FOV is wide and the gun is close

[frigid sequoia]

I mean, it seems that it looks fine in the editor isn't it?

[swift crag]

pistols aren't supposed to be melted

[polar acorn]

No, it's warped there too, that's why it's not likely to be FOV

[frigid sequoia]

How does the model of the gun looks normally?

[brazen canyon]

Can you explain each dot please ?

[swift crag]

Each item in that list is a game object

So the hierarchy should be:

Player: Has the "player" component on it

It has two children

Visual: Has the MeshRenderer. Can be scaled however you want.

Camera: Is the camera. Has the gun as a child.

Only "Visual" is non-uniformly scaled

Everything else should just be [1, 1, 1]

(which is both uniformly scaled and the default scale)

[polar acorn]

Objects

[earnest atlas]

is there a way to make a gun look at something?

Lookat rotates entire object I want to make sure its base is connected.

[polar acorn]

LookAt but with a proper pivot set up

[earnest atlas]

So same look at

[verbal dome]

Could calculate a direction from the desired pivot point to the look position, the put that into Quaternion.LookRotation

[swift crag]

I want to make sure its base is connected.

As in, you want to make sure it still appears to be held?

then yeah, just fix its pivot point

[verbal dome]

I was thinking like keeping the stock shouldered. But maybe im overthinking it

[earnest atlas]

What is pivot point 😄

[swift crag]

Make sure that your scene view is set to "Pivot", not "Center", in the top left

The pivot point is then wherever the gizmos appear.

If the pivot point is not where the weapon should pivot around, then parent the weapon to an empty object and reposition it

[earnest atlas]

oh

I think I understand

[midnight sinew]

How to learn code

[earnest atlas]

with eyes

[frigid sequoia]

You choose something simple that you want to do and try to do it, whenever you don't know how to continue, you search online or ask other people

And repeat with something a bit more complex each time
