[vocal marlin]

especially timers

[willow scroll]

If it collides, what then?

[vocal marlin]

by not working do you mean it just isn't doing anything?

[abstract finch]

Keep going until a full circle is reached, if theres no dash direction then no dash

[vocal marlin]

have you used a Debug to see if that part of code is being reached?

[long tiger]

yea the timer works fine i just want it to stop when the player enters the trigger lmao

[willow scroll]

Alright. That's what I'm referring to. How do you prefer to check the whole circle using raycasts?

[vocal marlin]

also have you checked if you have changed the tag of the player? or if either objects have a trigger collider?

[eternal needle]

By the way you can also just construct the rotation once then just keep rotating the vector. Basically store the rotated vector and keep rotating it, rather than adjusting the quaternion and rotating the initial

[willow scroll]

Unity uses 6 digits after a number, so it's from 0 to 360 million Raycasts to be done

[abstract finch]

    {
        while (true)
        {
            float anglesChecked = 0;
            while (anglesChecked < 360)
            {
                Quaternion axisRotation = Quaternion.AngleAxis(anglesChecked, Vector3.up);
                Debug.DrawRay(transform.position, axisRotation * startDirection, Color.red);
                //transform.rotation = axisRotation;
                anglesChecked += _angleStepSpeed * Time.deltaTime;
                yield return null;
            }
        }
    }```
Heres the code. I just do 360 from the angle in a coroutine. (In the real code theres no coroutine)

[long tiger]

yea i checked the player's tag is set to tag and the Is Trigger is set on

[vocal marlin]

I think your best course of action right now is just using a Debug.Log() to see if the code is being reached

[long tiger]

wait i think I found the issue

[long tiger]

aight ill do that and try the issue i think its casuing thanks

[abstract finch]

construct the rotation once then just keep rotating the vector.

How would I be able to do this? I'm not very good with v3s and quaternions is it hard to do?

[long tiger]

yep got it working turns out i had the script set in a different objects so it wasnt following the object with the trigger oops lol

[willow scroll]

This is unprecise and will affect the performance if wanted to be done more precisely

I'm sure it can be done with math

[vocal marlin]

oh ok that makes sense, good luck with your coding journey!

[eternal needle]

It's the exact same as what you're doing now, but you store the rotated vector. Il type psuedo code cause on mobile.
Vector3 rayDirection = something;
Quaternion rotateDirection = Quaternion.AngleAxis(stuff)
...
rayDirection = rotateDirection * rayDirection;

[abstract finch]

noted, right now im having trouble getting it to do a radial check in the direction i want which is upwards. At the moment it goes around.

[eternal needle]

There is literally no solution that will avoid physics casts if they want it to not dash into colliders.

[willow scroll]

There most definitely is

[eternal needle]

I'm not sure what you mean by radial check in the upwards direction

[eternal needle]

Well goodluck trying to solve that purely with math, having no knowledge of the colliders around. Unless you want to manually calculate which area is free based off each part of a non primitive collider

[willow scroll]

Well, I'll try to come up with a solution when I am free

Also, "having no knowledge" about the colliders around is entirely false

Simply use SphereCast with the suitable radius

[abstract finch]

Well to simplify it, its just looking a direction that has a clear path like no walls or anything to move toward

some monsters in games have a quick side step move, its basically that

except in this case the enemy isnt limited being grounded it can go up or down

[eternal needle]

Ok so did you read the last part of my message? What is your plan when you have a giant wall or a completely unique shape like a half moon

[eternal needle]

I understand the case, which is why I think raycasts here is a fine solution.

[abstract finch]

yea im using that

im just trying to figure out how i can make this ray move along a different direction but i can try on my own

[willow scroll]

Simply find the maximum and minimum positions in the perpendicular direction of the distance between the centers

[eternal needle]

Ok so it's as I thought, there is no plan for unique shapes. This would cause the AI to possibly not dash into areas where it could

And if you try to deal with those cases, itll sure as hell be more expensive than doing like 8 raycasts.

[abstract finch]

my game is simple and uses simple structures that are square if the first check fails i place a cooldown on it regardless

why does unity allow me to do Quaternion * Vector3 but not the other way around?

[eternal needle]

It is not commutative, meaning ab is not the same as ba.
I often forget which order is the correct one, but at least theres an error if you try the wrong way.

[gaunt ice]

A*B!=B*A
matrix multiplication is non commutative

[abstract finch]

i see

[eternal needle]

Ah discord formatting. It italicized my message lol

[silent prism]

hey guys i want to set the time of my animation to the float value in the script how can i do this

[sullen rock]

Hey, sorry for reposting, feels like my question got a little burried, so Im asking again https://gdl.space/tacapodabe.cs

Script #2 creates a texture and applies it, but when I try to get textureCoords from the raycast in script #1 it always returns (0,0). Can anybody help me figure out why?

[modern mesa]

hello

i have a maths project and i have to visualize a spherical triangle

[abstract finch]

    {
        float anglesChecked = 0;
        Vector3 axisV3 = Vector3.forward;
        while (anglesChecked < 360)
        {
            Quaternion axisRotation = Quaternion.AngleAxis(anglesChecked, axisV3);
            Vector3 direction = axisRotation * startDirection;
            if (!Physics.Raycast(pos, direction, checkLength, obstacleMask))
            {
                return direction; // Found Direction 
            }
            anglesChecked++;
        }
        Debug.LogError("Failed To Find Clear Path");
        return Vector3.zero;
    }```
Heres the final function

[modern mesa]

the teacher allowed help of ai and stuff so ive been using chatgpt to help me

void DrawCurvedLine(Vector3 startPoint, Vector3 endPoint, int pointCount)
{
GameObject lineObject = new GameObject("CurvedLine");
LineRenderer lineRenderer = lineObject.AddComponent<LineRenderer>();
lineRenderer.startWidth = 0.1f;
lineRenderer.endWidth = 0.1f;
lineRenderer.positionCount = pointCount;

    Vector3[] points = new Vector3[pointCount];
    for (int i = 0; i < pointCount; i++)
    {
        float t = i / (float)(pointCount - 1);
        points[i] = Vector3.Slerp(startPoint, endPoint, t); // Adjust for sphere radius
    }
   
    lineRenderer.SetPositions(points);
}

but this code doesnt work as i want

it creates a curved line between two points i selected on the sphere but the line is inverted and the lines cull

[eternal needle]

https://docs.unity3d.com/ScriptReference/RaycastHit-textureCoord.html
Just to make sure, it is hitting a mesh collider right?

[eternal needle]

I would increase the angle by a bit, like 10 or 30. This would still be checking a lot of directions.

[sullen rock]

It is

[eternal needle]

Is the mesh readable? It should have read and write enabled

[abstract finch]

good idea thanks

[sullen rock]

Toggling convex off fixed it it seems

[onyx tusk]

how 2 make 2d buttons dynammically?

[deft grail]

in what way do you want to make them dynamically

[hazy minnow]

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

public class DinoJumpScript : MonoBehaviour
{
    public bool grounded;
    public float speed;
    public Rigidbody2D myrigidbody2D;
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space) == true && grounded == true)
        {
            myrigidbody2D.velocity = Vector2.up * speed;
        }
    }
}
``` ```using System.Collections;
using System.Collections.Generic;
using UnityEditor.Experimental.GraphView;
using UnityEngine;

public class onGroundScript : MonoBehaviour
{   
    public DinoJumpScript script;
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        
    }
    private void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.gameObject.layer == 3)
        {
            script.grounded = true;
        }
    }
}
``` Why the player can still jump ?

[onyx tusk]

anyway, the main thing is that it works

[slender nymph]

you never set grounded to false. but also, relying on OnTriggerEnter2D is a pretty bad way to do a ground check, especially with the manual layer check like that

[hazy minnow]

What is the correct way to do a ground check

[slender nymph]

physics queries like a raycast, overlapcircle, etc are preferred over physics messages

[hazy minnow]

ok

[onyx tusk]

how 2 make 2d buttons dynammically?

[slender nymph]

did you plan on answering this follow up question so anyone could possibly know wtf you are actually trying to achieve? #💻┃code-beginner message

[deft grail]

#💻┃code-beginner message
i thought you said it works? yet your still asking the same question?

[onyx tusk]

didn't i answered?

[slender nymph]

what you replied was not actually an answer to the question that was asked

they were not asking how you planned to implement that feature since, you know, that was the whole basis of your question. they were asking what you were actually trying to achieve so that an answer could be provided

[onyx tusk]

i mean that i want 2 create it on runtime any way, but this way must work

[slender nymph]

just saying "2d buttons dynamically" doesn't actually say anything

[onyx tusk]

creating on runtime?

[deft grail]

what way, what do you want to do

[slender nymph]

didn't you know gr4ss, they want to create it on runtime

[slender nymph]

if you cannot describe what you are actually trying to do then you will not be able to get help since nobody knows what you are struggling to accomplish

[deft grail]

Instantiate(myButton) run that twice, done

[onyx tusk]

if i know way, i wouldn't ask

[onyx tusk]

guy, it's genious

& can i through it use gameObject.GetComponent<Button>()?

[deft grail]

sure?

or just instantiate of type Button, then you dont need to GetComponent

[safe ingot]

Hello, please advise what is the best way to implement multiplayer, if I want to implement a game in which the game state will be stored on the server, are there any tools?

[green ether]

Alot, but multiplayer is pretty difficult

I am using Mirror and it took me months to learn the basics and hook everything up to steamworks etc aswell

[slender nymph]

you'll have to research the available networking solutions and decide which fits your needs best. networking is not a beginner topic though. if you do not have experience with making a full game in unity yet, it is not a good idea to try to do multiplayer. but once you have chosen a networking solution you can ask for help in #archived-networking when you inevitably need some help with it

[safe ingot]

i worked with jmonkeyengine

[safe ingot]

before, but

[slender nymph]

well last time i checked jmonkeyengine is not the unity engine

[safe ingot]

yes, I just worked with it and it was possible to create headless server, and put logic into it but in unity i cant find information about it

[slender nymph]

there isn't just a magical "make a multiplayer game" feature in Unity. you need to research the available networking frameworks, choose the one that best fits your needs, then learn how to use that framework

[scarlet skiff]

I feel like now that i know more about coroutines i feel like Invoke is kinda useless, except maybe for when you have a very simple method. But other than that, the fact that you have to input the function as a string of its name for invoke, disallowing you from using method with parameters, just makes invoke useless, or am i missing something?

[safe ingot]

a lot of uselles information and service where you can create sh1ty multiplayer clone with juts sync

Is there really no option to create a headless server and override methods? onjoin onquit sendmessage etc

[slender nymph]

no, that's pretty accurate. another bad thing about Invoke is that it uses reflection to invoke the method, which means you cannot use local methods. there's also no proper compile time checking with invoking a method using Invoke since, like you said, it just uses the name of the method as a string

[slender nymph]

you are free to create this functionality yourself. of course you'll have to actually understand networking. otherwise stop ignoring what i've been telling you this whole time

[safe ingot]

ye but i guess mirror its just sync service and cant apply any logic right?

[green ether]

You can have a standalone mirror server or have a client host

As far as Im aware

[safe ingot]

I’m just asking if there really isn’t such functionality in unity, because in the damn monkeyengine you can run headless server mode, and override key methods,It's just strange that there is no such thing in Unity

[slender nymph]

you can create a headless server for unity. that doesn't mean you still don't need to choose a fucking networking solution that has the capabilities to do what you want

there are dozens of networking solutions you can choose from, you need to research them to find the one that best fits your needs. otherwise you need to do it yourself

we couldn't possibly know what is wrong with that little info. please see #854851968446365696 for what to include when asking for help

[safe ingot]

@slender nymph what do you mean by network solution

[slender nymph]

i mean a framework that does the networking for you because there is no built in multiplayer functionality in the unity engine. if you'd bothered to do any research about this, you'd know that

[safe ingot]

Do you really think that I didn’t search on the Internet?

[slender nymph]

it's pretty clear that you didn't

[safe ingot]

It’s obvious that I came here to ask people who have experience so that they could give me advice, and not just write blah blah blah you’re a s*cker and don’t look at the Internet for "Networj solution"

[slender nymph]

alright, this conversation is pointless. i'm going to block you now. good luck with your fruitless attempt at doing multiplayer since you clearly have no idea what is required for that

[safe ingot]

Where did you get this and how did you understand it?

[ocean dove]

Imagine calling 360 (or 36 or idk how many) raycasts

[safe ingot]

Do you read people's thoughts?

[soft kernel]

and?

[slender nymph]

it's really not that expensive

this isn't godot where a single raycast allocates like 600 bytes

[ocean dove]

How is 360 raycasts not expensive

That's probably about -0.5 to -2ms cpu

[slender nymph]

have you done any profiling to determine if it is in fact expensive? or are you just assuming that big number == big performance hit

[ocean dove]

Trust me I have

even shooting 256 raycasts takes a big hit on perfomance

[slender nymph]

show your results then

[soft kernel]

I had about 80 enemies, each sending about 8 raycasts every frame trying to find player

didn't see any performance issue

[ocean dove]

Oh what, I'm supposed to magically pull out code that I removed and or heavily edited to improve perfomance?

[ocean dove]

For vision or what?

[soft kernel]

https://youtu.be/Xd4UhJufTx4?si=tmE9j7anPh8o90-U
you can watch this to get better idea

[slender nymph]

well you claimed to have actually profiled it to prove a performance issue. you made the claim, the burden of proof is on you.

[ocean dove]

I'm not planning on finding the code

It's already gone

and I won't bother proving you as I saw your previous argument

[soft kernel]

for finding the direction to walk and checking the player direction

[ocean dove]

You went so quick from telliong someone to search up networking solutions to blocking them

[slender nymph]

then what was the point of you coming in here about 360 raycasts?

[ocean dove]

Navmesh or rigidbody?

[soft kernel]

rigidbody

[slender nymph]

yes, i entertained their delusions for 20 minutes before i blocked them because they didn't bother doing any research about networking in unity and just assumed that they could just magically create a headless server with "onjoin" and "onquit" functionality

[soft kernel]

and it was HDRP

[ocean dove]

Finding directions using your solution is understandable

So you target high spec devices

[soft kernel]

they were zombies so I didn't need smart path finding

[soft kernel]

I was

[ocean dove]

I target low end so I have to optimize my code haard

I tried doing raycast culling and it was a horrible idea for me

[soft kernel]

what are you using raycast for

[ocean dove]

as I mentioned, culling. But that code is long gone as even on 256 raycasts the accuracy was bad and the fps was even more horrible than it was without it

I think I got like -50 fps just from rays on a for loop

Doing huge amounts off of raycasts should be done asynchronously in order to split the amount of rays that are shot out over a larger amount of time which should theoretically improve perfomance

which I have not done and it went horribly wrong

[soft kernel]

why using rays for culling

[ocean dove]

Physics culliong is slow

Trigger culling is way faster and I could replace my other system for cullingn with it

The best part about trigger culling is that it's just a trigger and objects have ontriggerenter and ontriggerexit methods in em

It's the fastest range and the best culling method if you don't want to have large floors disappear as the default camera cull spheres tend do to that

[soft kernel]

are you sure the problem is with the rays it self and not the thing you do with that info?

in pc, I don't think sending 300 rays would take more then 1ms. how slow can a low end device be?

[slender nymph]

doing 1000 raycasts takes no more than 0.5ms. 360 raycasts took under 0.2ms on average, it's really not that expensive

the expense probably came with either not using non alloc versions of queries that return multiple results, or whatever you were doing with the results

[soft kernel]

isn't the non alloc slower? it just prevents garbage

[slender nymph]

the garbage is going to be the biggest performance hit when the GC runs

but i can test what is faster real quick

[soft kernel]

but in a longer gameplay time

what I mean is the result would be even faster for a short test

[vernal bone]

Need help.
Trying to make a moving platform, and as internet said, easiest way to make player move with platform is to set platform as player's parent.

Everything works fine, but when i exit the "play" while player agent still on platform, editor gives an error:
"Cannot set the parent of the GameObject while activating or deactivating the parent GameObject"

What can i do with this?

[slender nymph]

it's a very minor difference that is almost not even worth worrying about, less than a tenth of a millisecond difference between 1k allocating and non allocating raycasts in a loop.
of course my test code allocated an array for each method call (but not each Raycast in the loop)

[soft kernel]

how do you set the parent? in update?

[vernal bone]

    void OnCollisionEnter2D(Collision2D collision){
        collision.gameObject.transform.SetParent(transform);
    }

    void OnCollisionExit2D(Collision2D collision){
        collision.gameObject.transform.parent = null;
    }

[slender nymph]

but we can safely conclude that the biggest hit to performance would be the GC when it cleans up all the garbage. this also doesn't account for when any colliders are found where the nonalloc overload will likely be faster since when the collection passed to it has fewer elements than the cast would have found when unbounded

[slender nymph]

OnCollisionExit2D is also called when exiting, it's kind of an annoying bug that unity does not consider a bug

[naive pawn]

i mean it Enter is called when you press play so i guess it kinda makes sense...

[vernal bone]

So, when i exit the playtest(? dont really know how it's called correctly) Unity fires OnCollisionExit2D event and tries to assign parent to player while being disabled at the same time?

[slender nymph]

yep. there's a Physics2D setting to prevent callbacksOnDisable just note that it affects everything, so that would include if you wanted to disable some object and get an OnXXXExit2D response at runtime too

[vernal bone]

Alright, will look for another way to do what i want, i guess.
Thank you big time.

[slender nymph]

unity told me that was "as designed" when i reported it as a bug a few months ago

[ember oasis]

how do I change the order in layer of a canvas button

[slender nymph]

UI draws based on order in hierarchy, move the object further down in the hierarchy to draw it on top of objects that are higher in the hierarchy

[ember oasis]

it is down in the hierarchy

[slender nymph]

well there's only one object on the canvas there so naturally its hierarchy order won't matter since that only affects how the UI draws

if you want to change how your ui appears with your world space objects then it depends on your canvas settings

[ember oasis]

no but like

its behind the background

[slender nymph]

this is not a code question btw
but again, it depends on your canvas settings

[wanton canyon]

so Im trying to make it so that you can pick up and throw slimes in my game. issue: the slimes have this giant WanderAI script that is a state machine controlling how they move, and it seems to reset their position to before you throw it. Im just at a loss on how to fix 😅 script for WanderAI: https://pastebin.com/hGYR6U9m I can also share the scripts that pick up/drop items as well if needed

[slender nymph]

if you're going to use pastebin, can you at least select the language so there's syntax highlighting instead of just a giant grey blob of text

[tawny bolt]

https://paste.ofcode.org/8N8DfMvdgUAGkbR2czKwhL --movement script
https://paste.ofcode.org/bdAW2xfsupdcxPA8DbfdVi --dash script
these are my code i have been using to create a dash function but its not working why ?

[slender nymph]

be more specific than "not working"

[ember oasis]

wouldn't it make more sense to have the dash inside of the movement script

[tawny bolt]

it does this when i press dash dosent increase my speed

[slender nymph]

welp paste.ofcode isn't working for me right now so i can't even view the code 🤷‍♂️

[ember oasis]

same here

[tawny bolt]

can i send you the code directly ?

[slender nymph]

no, just paste it to a different site

[tawny bolt]

ok

https://gdl.space/ubukakecot.cs -- dash script
https://gdl.space/ruzafotida.cs -- movement code

[slender nymph]

okay so for starters, your SpeedControl method limits the movement speed

[tawny bolt]

wdym where do i limit the speed can you highlight

[slender nymph]

your SpeedControl method

[tawny bolt]

how do i fix it ?>

// limit velocity if needed
if (flatVel.magnitude > moveSpeed)
{
Vector3 limitedVel = flatVel.normalized * moveSpeed;
rb.velocity = new Vector3(limitedVel.x, rb.velocity.y, limitedVel.z);
}

this is where i limit my speed

how do i make a limit of 20 except of 10

[ember oasis]

could someone post tutorial videos on how to create a pursuer ai that will chase you down

[green ether]

Is it possible to set one Objects RectTranstform on the canvas to the same position as another objects if that other Object is in a Grid LayoutGroup?

The object I wanna move is on the same canvas but outside of the layout group

[wintry quarry]

Vector3 limitedVel = Vector3.ClampMagnitude(flatVel, limit);```

[tawny bolt]

what is limit ?

an int ?

[young fossil]

Hi. So I've got a couple of places I think Static should be used but trying to use it sparingly. For example, I have a SceneLoader and I'm wondering if I make that static? Any ideas?

[young warren]

i would cheat by setting the object as the child of the one in the grid layout group, set the anchored Position to 0, then unparent. That might work

[wintry quarry]

a float. Whatever speed limit you want to set

[tawny bolt]

kk ima try it

[young warren]

is SceneLoader something that has to be in the scene?

like, is it a GameObject in the Hierarchy?

[young fossil]

I feel SceneLoader just doesn't need any more than one instance in any context. It handles the software's level loading, stuff like transitions and initialisation

[young warren]

doesn't need any more than one instance? that's perfect for singleton

[young fossil]

It is in DoNotDestroy

Yes, it is a singleton too

[young warren]

just make it a DontDestroyOnLoad singleton

then it's fine?

[young fossil]

Well, yea. But I'm wondering if I can use Static too

[young warren]

what? by it being a singleton, it means you can already refer to it using the typename, like a static variable

[young fossil]

It's fine, nothing criminal about leaving it a simple singleton

[tawny bolt]

can i you make it so that my max walkspeed is always stuck on 10 and only when dashing it turns higher

[young warren]

you are using static when you use a singleton

[young fossil]

Sorry I should be more speific, talking about Static fields and methods here

[young warren]

i see

[young fossil]

Not Static class

So for example, I have Load(Scene scene)

[young warren]

i can't really see any real benefit or downside to it, so if you could, you can?

it's just odd since it's already a singleton

[young fossil]

So for every script that uses Load, I of course need to get the SceneLoader script, which in Unity, is FindComponetByType()

Using static bypasses it

Better performance to my understanding

And easier readability

[young warren]

huh? but it's a singleton

are you misunderstanding how a singleton works?

you could just do SceneLoader.instance.YourMethod()

SceneLoader being the class type

[young fossil]

Oh... yea

[young warren]

why do you need to get the SceneLoader script?

[young fossil]

No no, I see how it literally is static now

[young warren]

yeah

see why I was confused? 😆

[young fossil]

Yep xDD sorry

[young warren]

it's good that you're thinking outside the box though, no harm in that

[young fossil]

Static seems really rare use case in Unity then

[young warren]

happy devving

[young fossil]

Thanks Wytea!!

[carmine frost]

Sorry if im stupid, but why does the target not registre hit?
When the target script is called "target" only, it works?

[deft grail]

first you have an error

2, because you are probably using the name target in the other script instead of target1

[cinder crag]

why does this appear brbrbrbrbrbr

[amber basin]

How do i keep my game from breaking whenever i press pause, then go to the mainmenu, then back to the same stage? I have this little tower defence game i am working on rn and i am veeeeery new to coding.

[deft grail]

the object with this script doesnt have the GetWeaponItem script probably

or weapon is null

[deft grail]

how does it break?

[amber basin]

I have this little overview of all the UI and everything that has these values randomly selected. These values arent actually the ones i am working with, but i am using this as a sort of way to know that A. the game is not on and B. in case i run into the kind of bugs i have right now.
The game stays at this screen, no enemies spawn, i can build turret and pausing and retrying does not help at all.

[deft grail]

so the game basically just doesnt "start"?

[flat summit]

To grab different gun type scriptable objects in my game I just made a gun manager in the hierarchy with a simple script that holds all of the guns, is this frowned upon?

[deft grail]

you got to do it somehow, as long as it works and its not too messy then its fine

[amber basin]

Exactly! The game runs fine, i then go to the mainmenu from the pause screen, press play, it takes me to my level selector, i choose the same level and boom, its stuck, not playing at all

[deft grail]

then you need to call a method that will reset the game and play it, or you already have one which you forgot to setup

[amber basin]

I have a retry button that retrys the current level i am on but it does not work either?

[cinder crag]

tried to check if the weapon isnt null but welp doesnt work

[deft grail]

uhhh, the error is on line 21, checking if its null and using it on line after wont do anything

[deft grail]

what does the retry actually do

whats the logic behind it

[ocean dove]

line 21 is you getting the weapon I'm pretty sure

[cinder crag]

what , i dont understand waht you mean

[deft grail]

whats the error with this code

is there an error?

because i see you changed the code actually

[cinder crag]

same error

[amber basin]

This is what it does "sceneFader.FadeTo(SceneManager.GetActiveScene().name);"

[deft grail]

so either equipmentManager or currentWeaponobject or weapon is null

[cinder crag]

put the public Weapon weapon another script i had that i could use

[amber basin]

There is also a toggle () as well

[deft grail]

and what does FadeTo do

[cinder crag]

oh damn

[wintry quarry]

sure just plug in whatever the current limit is.

change it based on those other things.

You can do whatever you want in programming

just write it

[amber basin]

It starts a Coroutine that is connected to some code that makes the scene fade in and out so it looks nice when you press retry or go to another level or the main menu.

[deft grail]

so does it do just SceneManager.LoadScene()?

[cinder crag]

seems like weapon is null

the only one that didnt get printed

[deft grail]

so make it not null, assign something to the slot

[amber basin]

How do you the the black box around the code part? I can also post the code that is directly connected to the FadeTo thing!

[deft grail]

for multiple lines you would do it a different way !code

i did and the error still appears

[deft grail]

before you set weapon, debug.log the thing you set weapon to

[deft grail]

now after you set weapon, debug.log weapon

[willow scroll]

Where is even the 24th line?

[willow scroll]

Well, do you get what might be null ?

[cinder crag]

probably weapon

[willow scroll]

It's either equipmentManager or currentWeaponObject

[willow scroll]

Haven't we explained you the null issues a few days ago?

The newWeapon isn't null, because there's nothing trying to access its fields on the 24th line

Simply check the equipmentManager and currentWeaponObject, the NullReferenceExceptions are the easiest to deal with.

[deft grail]

he already checked it

[cinder crag]

i alr checked if the equipmentmanager and currentwaponobject is null and they arent

[young fossil]

Hey guys, I have an FSM and looking for some advice with my naming.

Firstly, the type FSM.State is a delegate. Then the properties of that type have methods assigned to them. I have State properties for Menu, Gameplay, Cinematic.. etc since this FSM deals with the game state.

So for the type name, State is okay, since it is a generalised FSM class.

As for the properties, I was thinking something as simple as "MenuState" or "Menu". But I've also heard "OnMenuState" is good since it implies there's some form of action (in this case a method) when it is the active state. Keep in mind, each state has functionaility for entering, on update and exiting.

Then the method, I would call "MenuState" too, which I obiviously can't, since you can't have the same names. So maybe "MenuStateMethod"? Or another could be "PerformMenuState" to imply activation of some kind.

Let me know your advice

[willow scroll]

Well, there should be no problem then

[willow scroll]

Well,

• 1. It's impossible, otherwise you wouldn't get an error
• 2. You've literally shown that the currentWeaponObject is null on the screenshot you've sent #💻┃code-beginner message

[cinder crag]

currentWeaponObject isnt null tho , its weapon

lemme check again

[willow scroll]

Well, they're both null, of course, the error is thrown

Have you seen the screenshot you yourself have sent? There's written that the currentWeaponObject is null

[cinder crag]

okay it is null

[willow scroll]

Well, of course

[summer stump]

Distrusting the errors will make things a lot harder

[carmine frost]

not working

[willow scroll]

Now you should simply make it not null 😐

[young fossil]

Is this a load of gibberish?

[cinder crag]

how??

[willow scroll]

Well, I have to idea what you're trying to accomplish. Shouldn't you know it yourself..?

[carmine frost]

this is the target shooting, need it to work with script target1

[amber basin]

Okay now i am gonna go crazy, my retry button doesnt work either. The timer does not start and enemies down spawn either....

Is

(SceneManager.GetActiveScene().name);
``` not enough to reset a level?

[willow scroll]

I would call them this way

public delegate void State();

public State menuState = MenuState;
public State gameplayState = GameplayState;

public static void MenuState() { }

public static void GameplayState() { }

[willow scroll]

It doesn't reset a level. It simply gets an active scene.

You'll have to reset a level by actually loading the current scene

SceneManager.LoadScene(SceneManager.GetActiveScene().name);

[wintry quarry]

this doesn't do anything

[willow scroll]

Also make sure it's included in the build

[static bay]

Alright boys the objective is simple. Get Visual Studio Code actually working with Unity. For years this thing has freaked out either with formatting or some other bullshit.

It's time to conquer it.

I have uninstalled VS Code and removed all extensions/settings.

We're going in clean.

[wintry quarry]

Get Rider instead

Never look back

[tiny geyser]

I have a super entry level question if anyone has time on their hands to pm me, it's about a slightly annoying jump animation that I can't quite seem to get to play correctly.

[amber basin]

Thats the even weirder thing though, i am using ```cs
SceneManager.LoadScene(SceneManager.GetActiveScene().name);

But it just refuses to reset my scene

[wanton crater]

guys i have an image that is the child of a canvas ofc and when i did this it went to 0,0 of the world not the parent how do i fix that

[wintry quarry]

Is your code actually running? Use Debug.Log to check

[wanton crater]

i want it to be 0,0 of the canvas

[static bay]

The scene also needs to be in the build index I believe.

Or whatever that thing is called.

[wintry quarry]

localPosition

[amber basin]

Ye the scene is in the Buildindex

[amber basin]

Give me a sec and i will make a screenshot

[amber basin]

Both codes are working

[tiny geyser]

Wait dw turns out I'm him

[naive pawn]

uh do you still need help

you can just ask here

we can't moderate dms

[static bay]

Nope still doomed.

For some reason code I paste just refuses to get autoformatted like in Visual Studio.

And opening a code block doesn't create a new line before the first {

[naive pawn]

vscode has a format feature

i think it's ctrl+alt+f or smth

can't remember

[static bay]

I know it does, but its not doing it automatically.

[naive pawn]

i'd hazard a guess that this could be configured

[static bay]

for c#

[gaunt ice]

shift alt f

[static bay]

when I do some javascript work

[naive pawn]

you could probably set it to do so

[static bay]

it immediately autoformats regardless of any other input

[naive pawn]

seems like both are true for c#

[unreal pulsar]

Is there a easy fix to my issue of my player character having these weird ice physics? In which they won't stop sliding around weirdly?

[naive pawn]

increase friction?

[unreal pulsar]

Where do you find that? Rigid body?

[naive pawn]

yeah, in the material you set

[static bay]

This seems to cause another "action" to take place, so when I CTRL+Z it reverts to the un-formatted version.

Aka I need two undos to actually remove the paste.

[naive pawn]

right, that's what happens with js as well

at least, as far as i remember

[static bay]

You sure?

I could have sworn shit just works with JS.

Tbf, been a few months.

Might be gaslighting myself.

[naive pawn]

i mean, this isn't really broken

pasting is pasting, the setting just makes the paste trigger another action

[static bay]

It's just odd.

I would expect equivalent behavior across languages if the individual extensions for each language were doing their job.

[naive pawn]

just tested and yes it is a separate action

there's a split second where you can see the raw paste before it's formatted as well

[static bay]

And you have the auto formatting setting enabled?

[naive pawn]

i enabled it to test

[static bay]

Disable it and then try pasting.

[naive pawn]

it just does the raw paste

[static bay]

Really? Alright I must be losing it.

[naive pawn]

i mean, could be another extension you have

[static bay]

I did a clean install of VS Code.

Removed all extensions and settings.

[naive pawn]

well the format on paste is off by default as i showed in my screenshot

[static bay]

I guess I'm just confused because new programmers come into this channel, with screenshots of VS Code, and the formatting looks completely fine and they have new lines on code blocks. I assumed this was default behaviour given by the extension.

[short hazel]

It is default behaviour, maybe you have an .editorconfig file that dictates other format guidelines and VSC bases itself on that?

VS and Rider both do that, if it finds such file in the project directory it overrides the format settings

[mighty cliff]

hello i have a little problem and i dont know how to fix it. My Character dont jump but i dont see the problem in the code. I am a rly new beginner and i have no idea why its not working maybe one of you have time to help me and talk with in a discord speach channel .

[static bay]

So I'm not crazy?

Wat da fuk

[naive pawn]

there's a separate format on save thing

it's also off by default though.

[static bay]

Actually just to make sure. What's supposed to be default? Should it format on paste? New line for code block? What's expected?

[gaunt ice]

you need some extension for editorconfig to work in vscode iirc

[naive pawn]

maybe you're just getting lucky with the snippets you witness? ive seen many instances of non-perfectly-formatted code throughout my experience as a helper in communities like these, albeit not in c# (i haven't been active here for long)

[short hazel]

VS formats on paste, and adds missing using directives if required. It does log the format as an action, so you need to Ctrl+Z twice to undo the paste. As for editorconfig I have no idea

It's properly configured though, right? You get the completion list and errors underlined

[naive pawn]

oh right, vs is more common

i mean vs and vscode do look kinda similar if i recall correctly

[static bay]

Nah both have distinct default themes. You can pick them out.

[naive pawn]

true

[static bay]

Ya it's configured properly. I'm getting underlining, intellisense and auto complete.

Oh and get a load of this.

look at this for loop

just wrote it normally

I copy it

and when I paste it

auto format puts the new line in the for loop block

but when I TYPE it it does not

[naive pawn]

right, that's a separate thing

[short hazel]

Do you have code style preference settings in VSC? They might be disabled

[static bay]

I am on a completely fresh install. Removed all settings and extensions prior to doing this.

But I will check, where can I find that?

[short hazel]

Good question

Settings of the C# extension, probably

[static bay]

alright one of these shmucks then

[short hazel]

That would be the second one.
Before that can you test something out? Inside Update or any other method, hit backspace until you have no indentation left, then invoke a snippet (type for and Tab twice to insert it), does it format the whole thing correctly?

[static bay]

you mean like this?

[short hazel]

Yeah and then inside the braces {} type for and tab twice

[static bay]

oh that's not good

I wrote for, and then the intellisense menu opened up

first tab closed the menu

second tab actually did a tab

snippets broken

[short hazel]

Weird

[static bay]

this has been my life

with C# VS Code

It just seems to be completely broken on this PC

and I dont know why

but I do get this

and when I select it

when done in a properly formatted code block it does it right

[short hazel]

Hm yep seems like it's not applying format by default. Trying on my side

[static bay]

I am sad

[static bay]

thanks

[short hazel]

Yup not formatting either on my side lol

Even if the setting is enabled

[static bay]

what is going on

[short hazel]

Well for the braces, if I add a newline before opening them, it works.
Newline, open brace, enter.
But not open brace, enter

[static bay]

I've got that too.

[short hazel]

Haven't found any code style setting so I think it's not shipped by default for VSC

Found a "format on type" setting but it does nothing, that's a bummer

[young fossil]

Very similar to whar I have now, which is great. Question though, does that break C#'s standard convention?

[willow scroll]

No, I don't think it does

[young fossil]

Since they're properties I thought it was PascalCase

But does the fact they're delegates override that?

[short hazel]

Properties are supposed to be in PascalCase, but the two of type State are (1) not properties, and (2) even Unity does not capitalize properties (see: transform, gameObject, etc.)

It's pretty much freesyled in terms of naming conventions, but you do whatever you think is best

[willow scroll]

They're not properties, in the case I sent, so it's thisCase

[young fossil]

That isn't a property?

public FSM.State MenuState { get; private set; }

[short hazel]

That is one yes

[willow scroll]

This one is

[short hazel]

It's a field when there is no accessors block after the name

[young fossil]

Sorry may have not explained it, that is how they're syntactically written in my context

So then we run into MenuState and MenuState

[willow scroll]

In this case it should be called MenuState

[young fossil]

Yes, I am aware unity doesn't but for this project I am abiding to C# standard

[short hazel]

Good

[willow scroll]

You'll even get an IDE1006 if you name it menuState

[young fossil]

Also this is definitely true. In my case it isn't but it is specific. If I had the liberty I would

[young fossil]

Damn... Annoying. Yea, it's been bothering me, I can't think of a good name... Any more suggestions?

It's a pretty vital part of my gameloop which is referenced a lot, so it does really matter

Hmm... What about MenuStateRunning for the method

[short hazel]

CurrentMenuState?If that's supposed to reflect the current menu state

[young fossil]

Yea, that's a good one, although there isn't variation in menu states

So there is only one menu state

[short hazel]

Hm why make a state machine for it then, if it never changes. Might as well make it get-only

[young fossil]

No no, it has states. Just not ones speific to menus, only a single "Menu" state

So there is a Gameplay state, a Cinematic state, etc

[short hazel]

Right so it's the "Menu" part of the name that shouldn't be there :)

[willow scroll]

What about this?

public delegate void StateCallback();

public StateCallback MenuStateCallback { get; private set; } = MenuState;
public StateCallback GameplayStateCallback { get; private set; } = GameplayState;

public static void MenuState() { }

public static void GameplayState() { }

[young fossil]

No, because MenuState exists for the context of game menus

[short hazel]

I don't follow. What class is this property in?

[young fossil]

I haven't used or seen the word "Callback" before, what does that mean? Also yea, this looks great

[young fossil]

My GameManager. Could be moved at a later date

[short hazel]

Okay so MenuState is alright

[young fossil]

Since it is a Game state, and it handles how the game behaviors

[naive pawn]

callbacks are functions that you give to other functions for that function to later call

[young fossil]

stuff like how cameras, timeframe, certain graphics behave etc

[young fossil]

Hmm... So my example is a Callback? a bit like cataclyst that makes other functions call?

[willow scroll]

So callback is something that holds a reference to the another method, which delegate does too and thus may be referred to as a callback

[young fossil]

Like dominos or something... Am I right?

[naive pawn]

i haven't been following so i can't answer that

but no to the latter

[willow scroll]

Yeah, that's so

[willow scroll]

delegates are callbacks

[naive pawn]

callbacks aren't a syntactic thing, they're just a term to specify intent

[harsh wraith]

I am having a problem in my game where my my player is floating when I start the game. I want my character to stay on the ground but I am unsure how.

[young fossil]

Ah this made sense... Got it

It's abstraction

[naive pawn]

if you've used stuff like ForEach or Map, the delegate you pass to those methods acts as a callback because ForEach will call that delegate to give info back to the caller

[willow scroll]

Where is the gravity for the character controller being applied?

[young fossil]

@naive pawn @willow scroll @short hazel Thank you guys for the help

[harsh wraith]

gravity for the character controller is applied in the Update()

specifically here in my script:

if (!characterController.isGrounded)
{
moveDirection.y -= gravity * Time.deltaTime;
}

[rich adder]

show the collider during playmode

[willow scroll]

What's the gravity?

[rich adder]

yeah you're gonna have to send the !code

public float gravity = 10f;

if (!characterController.isGrounded)
{
moveDirection.y -= gravity * Time.deltaTime;
}

[rich adder]

nothing is wrong inside the script, there has to be issue with collider

make sure they aren't any invisible colliders

also no point of having capsule collider there, the character controller component is already a capsule collider

You know what.. its probably the skin width... since you're using isGrounded from the built in CC not an overlap/cast

[harsh wraith]

So i just took away the capsule collider and tested the character controller on a different surface and the problem is still there. Here is more information about the scene:

[harsh wraith]

also if it is skin width how would I alter the skin width so that I can resolve my issue?

[rich adder]

look on the Character controller

play around with value but don't put it too low or might cause other issues

[harsh wraith]

yep that was the problem. Thank you so much for helping me!

[atomic sierra]

how would you go about making 2d square sprite to rotate its axis around? I dont have the project open but ive been meaning to ask.

right now the way my sprite VISUALLY rotates is through this code

Vector2 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
Vector2 dir = new Vector2(mousePos.x - player.transform.position.x, mousePos.y - player.transform.position.y);

player.transform.up = dir;

but ive seen that when i run the game and i look at the scene menu, my sprite object doesnt rotate its axis at all. it just VISUALLY looks like its rotating. im trying to make it shoot bullets and for the bullet to match the sprite's rotation, but its going straight up

So how would i go about doing this?

[short hazel]

That rotates. Maybe your Move Tool gizmo was in world space mode, in which case the arrows don't rotate at all?

And for the shooting you'll need to use transform.up instead of Vector3.up in the bullet direction calculation

[grizzled zealot]

Am I am doing anything wrong when I have about 20+ scripts on each object? moveable, health, shoot, spawnable, dockable, chatable, selectable, faction, ... and for each of them I have 3 scripts: model with the data, controller or presenter depending on MVC or MVP, and a view to any visual things.

now when I have 30 GOs in the view, I have 600+ scripts active.

Am I am doing something wrong? Is there any concern with being this deep into composition patterns?

[queen adder]

how can i add text that tracks your highscore in my game?

[ivory bobcat]

Break the problem down.

• Add some text to the scene that would hold the high score value.

• Have a high score value that updates correctly relative to the current score

• Update the text when high score value changes

Maybe show what the error is

[acoustic arch]

i figured it out

[winter cedar]

So when i open my project settings unity crashes

[timber tide]

I doubt it's much of a problem but remove unused update loops from each component if you haven't. There is one optimization you can consider later and it's that is if you're doing GetComponent search through a single gameobject each frame it may be wise to group your components a bit more if possible, but unless you're running into hiccups I doubt it matters right now

[grizzled zealot]

Most of the comonents don't have an update() method. If the components don't have an update() method, do I still lose performance?

[timber tide]

The only issue about having a large gameobject is using GetComponent on that gameobject as it'll have to search through all components until it finds one, so it can range anywhere from O(1) to 0(n)

but not likely to run into that issue unless you are making one of those large wave based games where you may be checking hundreds of gameobjects in a single frame

Unless GetComponent methods do use a hashtable but I can't really seem that specific information anywhere

[naive pawn]

Big-O is in terms of scale (at worst case) so it'd just be O(n)

[timber tide]

right, if it was a hash it would be big O of 1

It may be a hash actually

[naive pawn]

not necessarily since hashes can still collide

but in practice may as well be O(1)

[timber tide]

Well, if someone can find me the docs that confirms this stuff since I'm getting different answers from the forums rofl

but either way, working with gameobjects with a ton of scripts a little hard for me. I like to keep them minimal if possible

[grizzled zealot]

I'm not worried about getComponent, I'm more worried about constant broadcast messages update etc.

[timber tide]

if you remove Update method from your components it wont

[grizzled zealot]

Doesn't c# still have to inspect the monoscript to see whether it has an update method and, if so, call it?

[languid spire]

https://learn.microsoft.com/en-us/dotnet/standard/collections/hashtable-and-dictionary-collection-types

[grizzled zealot]

Or is this done more efficiently?

[naive pawn]

[...] the order that the components are checked is not defined
sounds like it's not linear, so i'd guess it's O(1)

[timber tide]

Was looking specifically if GetComponent uses a hash, or does it do some like linear lookup.

[naive pawn]

the presence of lifecycle methods wouldn't change at runtime, so i don't think it'd do the reflection every tick, instead being overhead on load/build

[languid spire]

pretty sure it's liniear as C++ does not implement anything like the Dictionary class

[timber tide]

Yeah, that's what I would expect, but I remember some forum posts that GetComponent does search in a orderly fashion but that wouldn't be the case with hash.

will have to test it to see who's lying to me haha

[abstract pelican]

Can you please tell me why it doesn't work? Why it won't shut down.

[ivory bobcat]

What do you mean by shut down?

[abstract pelican]

Well, it should be disabled by such a variable and the object should fall, but I have an object hanging in the air and the variable is not disabled.

[languid spire]

So is that code even running? Debug it

[ivory bobcat]

Maybe the inspector isn't focused on the correct object or the lines of code aren't ever executed?

[abstract pelican]

Some of the sites are working for some reason.

[rare basin]

just keep it organized

dont stack 20 scripts in one game object

i usually make sth like

• Enemy
  • Scripts
    • Health System
    • Loot System

everything nice and organized, 1 game object for 1 script

i hate crowded, unreadable inspectors

[static bay]

I'm sure it depends on what we're hashing, but Hashsets and Dictionary lookups only get more performant than a linear search through an array above 20ish elements.

If you have more than 20 components on a single gameoject you probably have other issues >_>

[final kestrel]

Hello all! A quick question. Should I learn Git using terminal? Or go with the desktop app?

[rare basin]

go with whatever you want

weird type of question

whatever suits you

[final kestrel]

Hm I was asking if one is better than the other actually in terms of flexibility and such.

[abstract pelican]

Up

[timber tide]

GUIs don't always have the tools you need, but I hear Fork does provide a lot of what you can do with the console

but that's like 50 bux

[final kestrel]

I understand. Thanks a lot!

[timber tide]

Like I have having problems reverting a specific file with GitHub Desktop so I had to do it through powershell

[final kestrel]

I am just a beginner so I just wanted to learn the one people use most.

[zenith cypress]

Fork has an indefinite evaluation period

[frosty lantern]

if I assign a struct in a component, am I passing a reference to the original?

[timber tide]

Oh, does it? I may look into that then cause I'm curious what it provides

[rich adder]

its like winrar

[zenith cypress]

Yep

[eternal needle]

Github desktop will be fine for what you need. You can always google the commands you need if there is truly something you need to do otherwise, I've yet to need to myself.

[final kestrel]

To me it seems easier since Its visuals! I may spend some time learning the terminal usage as well then.

[clever fable]

I think I've done this wrong, I sent my whole project file to a friend, he gets this errror: Assets\Scripts\EnemyFollow.cs(28,19): error CS0103: The name 'BulletLife' does not exist in the current context; can't reassign the script, I believe is the way i shared the project. Any fix or way of sharing the project that would fix this?

[rich adder]

How can you assign to something that isn't defined

whatever you got on line 28, it has no idea what BulletLife is

[eternal needle]

I used to only use the command prompt, swapping to a GUI was a night and day difference. No more spamming git diff because the GUI just has all the files and changes listed.

[stuck palm]

why isnt the master volume slider being selected?

void SelectOptionsFirstItem()
    {
        optionsButton.Select();
    }

[short hazel]

The method you posted seemingly selects a button, not a slider

Based on the variable names

[stuck palm]

sorry, poor naming

[short hazel]

In this case, make sure the GameObject the target Selectable is on is active and enabled, at the time .Select() is executed on it

// bad, I assume
btn.Select();
btn.gameObject.SetActive(true);

[stuck palm]

public void OpenOptionsScreen()
    {
        mainButtons.SetActive(false);
        optionsScreen.SetActive(true);
        SelectOptionsFirstItem();
    }

should be active

[short hazel]

Do you have an active EventSystem in the scene? The source code of Selectable.Select() just calls EventSystem.current.SetSelectedGameObject(gameObject)

[stuck palm]

I do have an active select system

i've made it inline now and its still not working

public void OpenOptionsScreen()
    {
        mainButtons.SetActive(false);
        optionsScreen.SetActive(true);
        EventSystem.current.SetSelectedGameObject(optionsButton);

[acoustic arch]

alright after figuring out the debugger I found an infinite code loop in lines 58 - 70

https://hastebin.com/share/omiyojibur.java

i know it has to do with the for loops repeating themselves but i cant figure out how

[short hazel]

(you didn't copy the URL after hitting "save" on the pastebin)

[acoustic arch]

im a goober

[short hazel]

Lines 62, 77: you increment i instead of n in your for loops!

The infinite loop occurs because n < userRuntimeDeck.Length always, since n does not change.

[acoustic arch]

i love you 👍

@short hazel

void SelectFirstItem()
    {
        if (!EventSystem.current.currentSelectedGameObject) {
            var child = mainButtons.gameObject.GetComponentInChildren<Selectable>();
            if (child)
                child.Select();
            print(child.name);
        }
        else
        {
            if (!EventSystem.current.currentSelectedGameObject.activeInHierarchy)
            {
                var child = mainButtons.gameObject.GetComponentInChildren<Selectable>();
                if (child)
                    child.Select();
                print(child.name);
            }
        }
        currentSelected = EventSystem.current.currentSelectedGameObject;
    }

i had this code line

it seems to be selecting play then moving to the new gameobject?

even tho its called after the gameobjects are set active

public void OpenOptionsScreen()
    {
        mainButtons.SetActive(false);
        optionsScreen.SetActive(true);
        SelectFirstItem();
    }

so i dont understand this

[short hazel]

Hm I don't remember if SetActive() effects immediately, but if it only applies on the next frame, then the event system may still see the object as inactive at the time it's activated

[stuck palm]

that is critical

[short hazel]

Can you try turning that piece of code into a coroutine, and placing a yield return null; before SelectFirstItem();?

[stuck palm]

selectfirst item or open options screen?

[short hazel]

In OpenOptionsScreen, on the line before you call SelectFirstItem()

[stuck palm]

okay will truy

[atomic sierra]

how do i get better at fixing my own bugs rather than waiting and relying on the responses of others?

[stuck palm]

public void OpenOptionsScreen()
    {
        StartCoroutine(OpenCoroutine());
    }

    IEnumerator OpenCoroutine()
    {
        mainButtons.SetActive(false);
        optionsScreen.SetActive(true);
        yield return null;
        SelectFirstItem();
    }

same thing unfortunately

[atomic sierra]

cuz im stuck on this 1 frustrating bug right now but i dont want to take the time to record it, screenshot the code, and wait for people to respond to help me out.

it makes the whole process of just learning seem slow

[slender nymph]

keep practicing until you understand what you are doing enough that you can recognize the bugs you have created

[atomic sierra]

so should i quit on this project or remake it enirely?

i mean i dont have that much done but is that the best i can do?

[slender nymph]

asking for help is part of learning. you can't get better if you don't learn from your mistakes. so if you just give up you won't have learned anything from whatever issue you are facing and will therefore not have had the experience of fixing it to rely on next time you face a similar issue

[atomic sierra]

ok then

i might as well post my issue here

[stuck palm]

@short hazel okay even if i do a coroutine and wait for 1 second it still selects play what is happening 😭

[short hazel]

Ah, because in SelectFirstItem you search components under mainButtons which is not where your slider is, from what I see of the Hierarchy

Can you try just doing like you had before with slider.Select()? But still using the coroutine

[brave acorn]

been working on a small 2d pixle art style game in unity for about a week now, I have a small map, player, idel, walking, jumping and falling animation, along with one enemy a slime, I also have a health bar, but since im still new ive think im not properly doing things, my game works but the health bar over the enermy isnt reacting to the player inpact, and its just static empty off the start. I have a couple of screen shots of all my, scripts and interactive sprites if somone would be willing to tell me what i could possibly be doing wrong and why this not working the way i want it too

[random ether]

guys ive made a rigid body based character controller and have added a slide mechanics that adds a constant force to the player when sliding. For some reason it doesnt conserve momentum the the player just stops after the slide. How to fix

[short hazel]

@stuck palm
If that doesn't work, change how your system works. Add a script on the object you want to activate when the menu is enabled, and just add this in the class:

private void OnEnable()
{
    if (TryGetComponent(out Selectable s))
        s.Select();
}

This will find the first Selectable on the same object and if it exists, select it.
It's half past by midnight so I'm logging off, you can still ping me for updates but I'll see them later tomorrow (today? lol)

[soft kernel]

do you move the player using velocity?

[stuck palm]

does onenable work when you setActive?

[short hazel]

Yes

[stuck palm]

i thought it just ran once

[stuck palm]

i'll try t that. dont i need to reference the event system though?

[random ether]

yes: void Move()
{
Vector3 currentVelocity = rb.velocity;
Vector3 targetVelocity = new Vector3(move.x, 0, move.y);
targetVelocity *= speed;

    //Align Direction
    targetVelocity = transform.TransformDirection(targetVelocity);

    //Calculate forces on player
    Vector3 velocityChange = (targetVelocity - currentVelocity);
    velocityChange = new Vector3(velocityChange.x, 0, velocityChange.z);

    //limit force (just in case)
    Vector3.ClampMagnitude(velocityChange, maxForce);

    rb.AddForce(velocityChange, ForceMode.VelocityChange);
}

[short hazel]

Every time the script/object is enabled. And no, you don't need an EventSystem reference, it's handled by the selectable

[random ether]

this is the move function

[short hazel]

Please embed !code as per the instructions below - this is very hard to read and not practical to copy-paste from!

!code

Ah, bot is ded

[brave acorn]

whats that?

[short hazel]

#854851968446365696 has the same instructions

[brave acorn]

first time on thsi dis

alr

!code

[random ether]

ii have no idea why the momentum isnt being conserved

is it because movement is interupting or sm?

[short hazel]

A bot usually responds to this, but seems like it's asleep like I should be rn

[soft kernel]

where do you apply velocity?

is this for movement or sliding?

[random ether]

this is for movement

this is sliding: private void StartSlide()
{
sliding = true;

    playerObj.localScale = new Vector3(playerObj.localScale.x, slideYScale, playerObj.localScale.z);
    rb.AddForce(Vector3.down * 5f, ForceMode.Impulse); //adds downward force so player comes to ground quicker

    slideTimer = maxSlideTime;
}

private void SlidingMovement()
{
Vector3 inputDirection = orientation.forward * verticalInput + orientation.right * horizontalInput;

    Vector3 slideDirection = orientation.forward;
    slideDirection.y = 0f;



    //rb.AddForce(inputDirection.normalized * slideForce, ForceMode.Force);
    rb.AddForce(slideDirection * slideForce, ForceMode.Force);

   
    slideTimer -= Time.deltaTime;
    
    if (slideTimer <= 0)
    {
        StopSlide();
    }

sliding movement adds the force

[brave acorn]

trying to get into game development, had an idea for a game but no idea really how to make one, been spending the past week learning basics off youtube, one thing i can say, i will never hate on a game dev ever again

[soft kernel]

so your regular movement is also based on force and not velocity

you add force in the direction you wanna move?

[soft kernel]

what does StopSlide do?

[random ether]

yes

[random ether]

it just sets the scale back to normal

as well as set the sliding boolean to false

[amber basin]

Okay big news. My reset button ACTUALLY works now but Going from being in a level, hitting pause, going back to the main menu, choosing the same level aaaaaaand it is still broken

No clue why xD

[stuck palm]

@short hazel still doesnt seem to work,

public class SelectOnEnable : MonoBehaviour
{
    private void OnEnable()
    {
        if (TryGetComponent(out Selectable s))
            s.Select();
        print(s.gameObject.name + "selected");
    }
}

i've made this class that selects on enable

applied it to my play button and my volume one, and it still doesnt seem to work

so extremely annoying for just a simple menu open

anyone else got a different implementation for menu changes?

[void thicket]

Does it get selected when you click with mouse?

[stuck palm]

i cant click it with the mouse at all lmao

[void thicket]

You cannot interact with the slider?

[stuck palm]

no not at all lmao

[void thicket]

Can you post the slider’s inspector

[stuck palm]

one sec

[stuck palm]

is this what u wanted to see

[void thicket]

Yeah.. first of all the using scale in UI is no-no, might be other invisible rect transform blocking it, but it shouldn’t stop you from select call 🤔

[stuck palm]

i know its so confusing 😭

might just use a home page from the asset store tbh

[sly wasp]

whenever I do
void OnCollisionEnter(Collision collision)
{
if (collision.gameObject.tag == "jetpack")
{
if (!isJetpackActive) { }
{
StartCoroutine(Jetpack());
}
}
if (collision.gameObject.tag == "gatesCam")
{
cam.GetComponent<Animator>().Play("Gates", -1, 0f);
}

}

it doesn't do anythin, and I am unsure how to fix it
The collider has is trigger on, the gameObject has collision components

[void thicket]

If you make a new bare slider game object from menu, can you interact with it?

[stuck palm]

no lmao just tried

[void thicket]

Weird, what about a button?

Only slider has issue?

[stuck palm]

button doesnt get acrtivated eaitehr

[hallow acorn]

hi could somebody help me with fixing my diagonal movement? its always faster then the horizontal or vertical movement

[void thicket]

Okay then it sounds like a big image or something is blocking your click

[void thicket]

Normalize the direction?

[hallow acorn]

ig?

[stuck palm]

i have a fade canvas thing, but its not selectable so it shouldnt be an issue

[void thicket]

https://docs.unity3d.com/ScriptReference/Vector3.Normalize.html

[hallow acorn]

its really that easy?

[void thicket]

Either that or the image you have in the bottom of the hierarchy. Images may not be selectable but it still blocks UI raycast

[stuck palm]

i've turned off the raycast target

[north drum]

help I am trying to make it so that when I walk up to something and look at it and press "E" it activates an animation but I dont know howe to code it so that it activates the trigger I set up in the animation tab
my code:https://wtools.io/paste-code/bUEJ

the trigger is called "press"

[summer stump]

Do you have a dynamic rigidbody on one of the objects?
Also, switch to .CompareTag("name") instead of .tag == "name"

[modest sierra]

Is there a reason on why I shouldnt organize my code to have 2 lines put together into 1 line?
Test line 1; test line 2;
rather than

test line 2;```

[summer stump]

No.

[modest sierra]

Cool

[summer stump]

You SHOULD have it as two lines

[stuck palm]

finally fixed it by doing this:

private void OnEnable()
    {
        if (TryGetComponent(out Selectable s))
            s.Select();
        print(s.gameObject.name + "selected");
    }

    private void Update()
    {
        if (EventSystem.current.currentSelectedGameObject == null)
        {
            if (TryGetComponent(out Selectable s))
                s.Select();
            print(s.gameObject.name + "selected");
        }
    }

[modest sierra]

cause it saves space

oh

[stuck palm]

dirty but gets the job done

[summer stump]

Oh, misread that

Definitely have it as two lines

[modest sierra]

Is there a difference though?

[summer stump]

Space saving is incredibly unimportant.
Readability is pretty much THE most important part of coding. Even more than performance to a certain point

[modest sierra]

Ok

[summer stump]

And the former is WAAAAAY more readable than having stacked up variables for no reason

[modest sierra]

In this scenario, since both lines do similar things, I thought I could combine em (the top line)

[summer stump]

To the compiler, there is no difference though

[summer stump]

That is awful. No offense

[modest sierra]

fine, then Ill keep it separate

[summer stump]

Always favor saving horizontal space over saving vertical space

I even split long statements vertically

[modest sierra]

ok

Im reworking my 214 lines of code to be more optimized and simpler to read

so yeah, just askin

[summer stump]

Split it into multiple classes
That's the way to make it more readable and modular

[modest sierra]

I already combined the position and rotation thingy

[modest sierra]

they already are

still a lot of mess

[summer stump]

Fair.
It's an ongoing process for sure

[modest sierra]

And a lot of it is ineffecient atm

Many lines of code that could be simpler being shorter

Hence why Im rewriting it with the new knowledge I have on what Im trying to achieve

I shouldve planned out my goal tbh

[summer stump]

Keep in mind that lines of code and line length have no affect on actual efficiency at all.
The compiler is going to rewrite it multiple times anyways

It's only the personal efficiency of being able to read it

And understand it six months later

[modest sierra]

Well yeah, but keeping the lines shorter also helps with readability in a way

[summer stump]

But yeah, refactoring as you gain new knowledge is gonna happen a loy

[modest sierra]

theres less area to look for

[summer stump]

Ehhh, it CAN sometimes.
But often making things longer with more descriptive names and clear separation is more readable.
But then you can hit a point where is is just spaghetti of course

It's a balance

[stuck palm]

except it doesnt work in BUILLDDDDDD

[modest sierra]

I had this at first

grabbedObject.transform.rotation = grabTransform.transform.rotation;```
which I then changed to
```grabbedObject.transform.SetPositionAndRotation(grabTransform.transform.position, grabTransform.transform.rotation);``` since most of the 2 lines are the same anyway

[summer stump]

Yeah, that is a fine change. I would write it like this usually

grabbedObject.transform.SetPositionAndRotation(
  grabTransform.transform.position, 
  grabTransform.transform.rotation);

Which brings it up to three lines hahaha

[modest sierra]

Guess we view it differently

The way you just described would honestly make me more confused 😅

[summer stump]

Yeah, once you have been doing it a decade or so, you just find that scrolling or jumping up and down is easy af, and panning horizontally is a pain

Or you might assume you know what the cut off code says, which is super dangerous.

[modest sierra]

I tend to use a lot of booleans when I dont have to

Like when I can just say example != null

rather than example == true

[north drum]

If sm1 doesnt mind can u pls see this

this has been bothering me for a very long time and I think its pretty basic

[wicked cairn]

YouTube “Unity trigger colliders”

[north drum]

im not trying to make an object a trigger im tryuing to make pressing a button activate an animation trigger

[wicked cairn]

A UI button?

[rocky canyon]

you mean a Trigger parameter within the Animator?

[north drum]

no a key on my keyboard

[rocky canyon]

you just access the animator and change the trigger..

[north drum]

ye I alr made the trigger

im js trying to bind it to a key

[rocky canyon]

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

animatorReference.SetTrigger("MyTrigger");

[north drum]

I have something really similiar to this

i acctually have this exactly

[rocky canyon]

if(Input.GetKeyDown(Keycode.Space){ ^ }

[north drum]

its giving me an eror

[rocky canyon]

well whats the error say?

[wicked cairn]

Then send the code

[north drum]

i did one sec

https://wtools.io/paste-code/bUEJ

the error is the toilet variable hasnt been assigned but I assigned it in the inspector and its still not working

[wicked cairn]

Public void Interact() won’t work it needs to be “public void Update()”

[rocky canyon]

^ yea unless ur calling Interact(); in your update loop that code isnt even running

[north drum]

oh ok one sec

ill js move it to the void update

[rocky canyon]

Update is a prebuilt function that gets called by Unity automatically every frame

changing its name broke that feature

[north drum]

ok but wait now it wants me to delete

interact()

I get that

but wont it make it so that pressing e activates the trigger

at any time

[sly wasp]

a child of the gameObject has a rigid body

[north drum]

im tyring to make it so when I look at the object

not js anytime

[rocky canyon]

that would require a bit more logic..

like a bool u enable when looking at it..

looking at it -> set bool to true

in update
if(pressbutton){
chck if lookin at it is true then allow code}

[north drum]

ok wait I think i fixed it

so when pressing e

[summer stump]

Then it won't work
Gotta be the object with the script, or the colliding object with the trigger collider

[north drum]

the animation sets

but now

the animation itself

is different then the one I created

and its breaking the object entirely

but I can see it transitioning in the animator tab

[sly wasp]

thank you for letting me know

i wasnt 100% sure on that

[willow relic]

I don’t understand

[north drum]

every time I press E the button I want the object js dissappears

[frosty lantern]

I have an enum that I am using for the validation of chess moves::

    public enum colorPiece { Dark = -1, Light = 1 };

    if ((int)BitBoard.positions[position + (move * (int)color)].color * (int)color == 1)
{
    valid = false;
}

the goal with the if statement is to prevent cannibalism, by getting the color of the piece in the projected square, multiplying it's color by the pieces color. If you get 1, [(-1x-1) or (1x1)] the move should be marked invalid before continuing on. this check works on the white pieces, but it doesn't work for the black pieces.

https://gdl.space/capilufugu.cs
the rest of the method if necessary

I swapped to directly test equality:

if (BitBoard.positions[position + (move * (int)color)].color == color)

and it still doesn't work, so it's not a math issue

[deft grail]

debug.log the result and see what it is and what you want it to be

[frigid sequoia]

There is no way of modifying an audio clip speed straigh out in Unity right?

Cause I kinda need some audio to match out an animation on a very precise manner

[summer stump]

Closest is adjusting the pitch.

Otherwise you need a 3rd party solution

[rocky canyon]

ya, or setup uir animations to be exact

w/o unknown transition speeds

A friend and I have been working on a wall slide that occurs when you press against a flat surface of an object (wall), if I'm wall sliding on the rotation the object is facing, I wall slide just fine, but whenever I try to wall slide on any other wall that faces a different direction, the character goes crazy trying to face the object's orientation. Is there a way to take the rotation or orientation of the face instead of the object? Does anyone have any insights on how I can handle this?

[deft grail]

no, ignore that

Hm after some reading it seems C# does not support covariance for arrays..

[polar acorn]

You need to create a new array of GameActions, you can't just put the curly braces. var[] array = new var[] {a, b, ...};

[spiral narwhal]

It's a property though

[polar acorn]

Doesn't matter

[polar acorn]

You're specifying the default value of a property

So you need to actually create the array to put the values in

[spiral narwhal]

Tbh, that's the most convoluted syntax I've ever heard of

You mean create an array somewhere in the constructor and then assign that to the property?

[polar acorn]

Not really. You have to create the array, then you can give it values

You create the container, then you can use the {} syntax to populate it

[spiral narwhal]

it gets called by itself, by unity

This section in the Player Movement handles the wall slide script:

if (wallCheck.wallD.z < 0f && currentMovement.z > 0f  currentMovement.z < 0f && wallCheck.wallD.z > 0f  currentMovement.x > 0f && wallCheck.wallD.x < 0f || currentMovement.x < 0f && wallCheck.wallD.x > 0f)
        {
            correctD = true;
        }
        else if (isMovementPressed){
            correctD = false;
        }

        if (wallCheck.isWall && currentMovement.y < -0.1f && isMovementPressed && correctD && isFalling && !wallSlide)
        {
            wallSlide = true;
            currentMovement.x = 0;
            currentMovement.z = 0;
            currentMovement.y = 0f;
           // transform.rotation = 
        }

        if (wallSlide == true && correctD == false) {
            wallSlide = false;
        }

And this one handles the Wall Detection for the player:

    public Quaternion wallrot;
    public Vector3 wallD;

[whole idol]

oh youre right

[frosty lantern]

yea that gets populated by your curly brackets

[summer stump]

Also, collider2d, not collider

[spiral narwhal]

But that's the same issue as before no?

[frosty lantern]

did you fill in the suggestion to test it?

[spiral narwhal]

What suggestion?

[whole idol]

thanks, i got it now, you're right

btw does anyone know why i get this?

[polar acorn]

Is this something you've actually typed in or a suggestion from your IDE you have not approved yet

[spiral narwhal]

It's @frosty lantern 's suggestion

[whole idol]

I have a prefab named pipes and inside of pipes I have an insivisible boxcollider item On Trigger, which is supposed to Debug.Log on the terminal that the player has officially passed on to the next level and will print a message on to the terminal

[polar acorn]

But it is in your code, right? Not an autocomplete you haven't confirmed?

[frosty lantern]

it shows up in your ide when you take a screenshot so if you didn't type it yourself your compiler is telling you how to fix it.

[whole idol]

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

public class next_level : MonoBehaviour
{

    public TMP_Text text;
    public GameObject m_clone;
    // Start is called before the first frame update
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {
        
    }
    private void OnTriggerEnter2D(Collider2D other)
    {
        if (other.tag == "NextLevelTag")
        {
            Debug.Log("Player passed through a pipe, score + 1 ");
        }
    }
}

[deft grail]

delete the script from your object and add it again

[spiral narwhal]

No this is the current version in my script:

        [ItemNotNull]
        public GameAction<IActionArgument>[] GameActions { get; } = {
            new AttackGameAction(),
            new MovementGameAction()
        };

Because of prettier

It automatically removes the unnecessary stuff

[polar acorn]

Then add in the thing the IDE is suggesting

[spiral narwhal]

There is nothing it suggests though

[frosty lantern]

click on the gray text and press tab

[spiral narwhal]

Nevermind my IDE, can you just tell me the syntax that allows me to initialise those two IActionArguments please?

[polar acorn]

Can you show the type definition for AttackGameAction

[spiral narwhal]

Yes

    public class AttackGameAction : GameAction<AttackActionArgument>

    public class AttackActionArgument : IActionArgument
    {
    }

public abstract class GameAction<T> : IActionBehaviour<T> where T : IActionArgument

public interface IActionBehaviour<in T> where T : IActionArgument

[timber tide]

for the sake of testing, maybe forget the auto property for now and see if you can throw those into an array you initialized

[void thicket]

Type covariance only works for interface, not classes

[polar acorn]

Okay, so, I think the issue is that AttackGameAction takes specifically AttackActionArgument, but your list is expecting a GameAction that can take any IActionArgument? Essentially, your array is of a less specific typing than AttackGameAction

[spiral narwhal]

Type covariance only works for interface, not classes

What does this mean in my case. Those are both interfaces no?

[north kiln]

I don't see how AttackGameAction is an IActionArgument at all Ah, I missed the wrapping type

[spiral narwhal]

It is not

It is a GameAction<AttackActionArgument>

[void thicket]

GameAction<T> is not interface, so you cannot have it reference to covariance T

[spiral narwhal]

Wdym, it's just a generic no? There is no compiler warning anywhere regarding that either

[void thicket]

List<object> x = new List<string>(); // wrong
IEnumerable<object> y = new List<string>(); // works

[spiral narwhal]

So how do I go from here

[whole idol]

The Debug.Log thing doesnt work

[spiral narwhal]

I just want an array of multiple objects that inherit from GameAction and implement IActionArgument

That's all I'm asking for, C# 😭

[void thicket]

One thing you can do, is for example using IActionBehaviour<IActionArgument>[] instead of GameAction<IActionArgument>[].
However you will have many limitations due to the nature of interfaces

[spiral narwhal]

Ok

I'll try around a bit, thanks everyone

Is there any way I could shorten this?

[void thicket]

First keep your coding convention consistent

[void thicket]

https://learn.microsoft.com/en-us/dotnet/csharp/fundamentals/coding-style/identifier-names

What is pipeSpawnVector for?
Is there a reason that spawner is responsible for moving and destroying? Otherwise you can split them into separate script and attach to spawned object.

[whole idol]

I dont want it to attach to a spawned object

I tried that many ways and it always creates exponential amount of spawnable objects

[modest sierra]

Doesn't c# compile the code?
Unity just behaved differently after I swapped 2 lines of code that should be runnning at the same time

[frosty hound]

Code doesn't run at the same time, it runs line by line

[modest sierra]

Then what is compiled vs interpreted?

I though interpreted was the line by line one

[modest sierra]

all my sources say otherwise so Im curious about that

Not saying that I dont believe you or that you are wrong, Im just newish to coding

[frosty hound]

Are you asking this in the context of Unity?

[modest sierra]

Yes

Oh

So Unity reads it line by line?

[slender bridge]

I'm sensing your question has nothing to do whether or not c# is compiled or interpreted.

[whole idol]

Anyway, does anyone know why this script that I got fails to debug.log that my player has touched the invisible line that is supposed to tell whether or not I went through a pipe?

Eventually this invisible barrier is supposed to let me know and update text automatically

[modest sierra]

Well, I know that C# is compiled, but the whole reading line by line part threw me off

[frosty hound]

Unity is single threaded, so it it will go line by line. You can look into DOTs if you need something otherwise, but that isn't something a beginner should even begin to consider.

[whole idol]

me?

[modest sierra]

Ok

Ill do a bit more research on that though, seems interesting

[whole idol]

btw this is the code...

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

public class next_level : MonoBehaviour
{

    public TMP_Text text;
    // Start is called before the first frame update
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {
        
    }
    private void OnTriggerEnter2D(Collider2D other)
    {
        if (other.tag == "NextLevelTag")
        {
            Debug.Log("Player passed through a pipe, score + 1 ");
        }
    }
}

[slender bridge]

does your player object have a rigidbody on it ?

[whole idol]

yep

[slender bridge]

is your collider on the next level line set to istrigger ?

[whole idol]

On the level: yes, on the player: no

[eternal needle]

Are you new to coding? I highly doubt you need dots or anything parallel tbh. You should say what your actual issue is.

[modest sierra]

Im a year-ish in

I have tackled DOTs before with tutorials

[whole idol]

The level doesn't actually exist into my hierarchy. (It's in a prefab )

[modest sierra]

But Im no where near proficient with C#

[summer stump]

This is about compilation, not how it actually runs. These are completely separate things

[modest sierra]

aight

[summer stump]

Show the collider gizmo
The collider component was also collapsed, which is pretty unhelpful

[whole idol]

and here's what it looks like if I turn the Sprite Renderer on

its a big fat pipe

[frozen burrow]

Is is possible to get the information from a face's orientation of an object?

[summer stump]

No need for the renderer component at all if it's invisible.

But anyways, is the player rigidbody dynamic? Or kinematic?

[slender bridge]

Put a debug log outside of the if statement and see if any trigger is happening. If it is, then i would ask if you have saved your scene since making that tag in the inspector.

[summer stump]

Like the normal?

[whole idol]

Dynamic

[frozen burrow]

Yeah, something like that :>

[whole idol]

I turned it Kinematic

and don't see a difference

Perhaps what is wrong is the way this OnTriggerEnter2D() is structured?

[slender bridge]

you should be using other.CompareTag("NextLevelTag"), but can you put a debug log outside of that if statement, run the game, and see if anything else is firing off ? like Debug.Log(other.name)

Also i could be wrong but it looks like the class name on that script doesnt match the class name of the file name

[rich adder]

its fine just horrible convention

[whole idol]

its pretty much the same except my convention

[summer stump]

It MUST be dynamic

[whole idol]

yeah I just realized that

[summer stump]

But try .CompareTag I guess

[whole idol]

it doenst move if its Kinematic

yeah im trying that rn, doesnt work either unfortunately

[slender bridge]

show me the file name of that class in your project folder, can you at least verify your start method can log a line out ?
