[slender nymph]

for example, if you instantiate the prefab that object is based on, it has nothing assigned in that field

[acoustic belfry]

sorry, im just trying to make it look "simpler?". Cuz i used the variables in an npc and made it glitch, so i thought using it directly would make it easier, cuz that fixed that npc

[kind spoke]

Genius

[rocky canyon]

i think ur issue was exactly what i thought it was.. ur clip was starting over and over and over...
here in my animator u can see that the idle clip LOOPS but the transition only ever happens when we go from something else -> Idle

if my animator was doing the issue u were having the little arrow going from entry to idle would be flickering non-stop

[proper needle]

my oncollisionenter isnt working

[slender nymph]

read the warning in your IDE and pay attention to your console in unity

and if that information is not sufficient, then go through this: https://unity.huh.how/physics-messages

[polar acorn]

What's the underline say

[proper needle]

incorrect signature

[polar acorn]

That would indeed be why it's not working. You need to have the correct signature

[proper needle]

it looks correct to me💀

[slender nymph]

then look at the docs

[polar acorn]

How about checking the documentation and seeing?

[proper needle]

alr gimme like 2 mins

[proper needle]

idk where to look in the documentation

[polar acorn]

Start by looking up the signature for that function

[rocky canyon]

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/MonoBehaviour.OnCollisionEnter2D.html

[rocky canyon]

here i'll start ya out

find their Example compare it to urs..

🎵 one of these is not like the other... 🎶

[proper needle]

i dont see anything useful

[polar acorn]

Tell me what the method signature is on the website

[proper needle]

nvm i see it

[polar acorn]

What does it return? What parameters does it take?

[proper needle]

its collision2d col is it

[proper needle]

a debug log, and collision2d col

[rocky canyon]

Collision2D vs Collider2D was the issue

[polar acorn]

Debug log is not part of the method signature

[proper needle]

isnt that what it returns

[polar acorn]

You can see what type it returns from the method signature

[kind spoke]

it sounds like you need some c# basics

[proper needle]

[frigid sequoia]

Line 27 is causing a NullReferenceException, but.... it's intentional? Like you are not supposed to need target, it can just be null, what's causing that?

[slender nymph]

playerAggro is null

[polar acorn]

you have conveniently cropped the line numbers out

[frigid sequoia]

Oh, ya sorry

Is the marked one

[polar acorn]

Then playerAggro is null

You can't get .target of null

[frigid sequoia]

It is, I thought that if the script is null any reference to it would be too

[kind spoke]

playerAgro?.target != null maybe works?

[slender nymph]

you cannot access target on a null playerAggro

[slender nymph]

do not use null conditional operators with objects deriving from UnityEngine

[polar acorn]

if playerAggro is null, then it's not a PlayerAggro, it's a null, and null doesn't have anything named .target

[frigid sequoia]

So this would work?

[kind spoke]

why is that?

[frigid sequoia]

It seems to work, ya

Just that it's not doing like anything at all lol

I will check it later I guess

Thank you

[polar acorn]

Unity has overridden == null for objects that have been destroyed, but not actually culled yet, that null coalescence doesn't include. So there are situations where someUnityObject == null would return true, but a null coalescence wouldn't think so

[slender nymph]

the null conditional operators do a pure null check that cannot be overridden. however UnityEngine.Objects can be a sort of fake null that happens when they are destroyed. using the == and != operators with UnityEngine.Object uses an overridden version of those operators to check for that fake null. if you don't do that proper check then something can be not null but still equate to null because it was destroyed but the variable was never set to null

[ivory bobcat]

You're 100% expecting a valid object (because you haven't got any null checks) but when accessing the member, you found that the member wasn't accessible because the referenced variable was null. Thus an null exception was thrown.

[rocky canyon]

the reason u saw the error in the first plce was because it was null..
now that u fixed that issue... it works correctly and returns false now in ur conditional..
you'll still need to figure out why its null.. if u were expecting it not to be

[kind spoke]

i thought c# didnt let you override ==,!=.

[slender nymph]

why would you assume that?

[kind spoke]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/operator-overloading#non-overloadable-operators

oh nvm i guess it is there...

[slender nymph]

notice how == and != are not listed there

[polar acorn]

Yeah, == and != aren't in that list

[frigid sequoia]

Ok, so last one of the day. How come that the health is modified and the timeSinceLastAttack is reset, but the print nevers shows?

I mean, it's working, but, wtf? How?

[slender nymph]

double check your console to make sure that you don't have either collapse enabled (so that all logs with the same content from the same source only appear as one log) or that you are not hiding logs

[frigid sequoia]

Where is toggle for that?

[slender nymph]

in the console

[frigid sequoia]

Oh, ok, I did close it somehow. I remembered this just showed again whenever a new log was added

Thank you

onEvent "IndubitablyITHAN" "Click" function("cry")

😭😭😭😭

[untold shore]

Hey, quick question. I'm attempting to just think through an animated counter for my game, labeled "Bet". Whenever it goes up, similar to a hand clicker (where you click the side and the dial moves to increase the number), the number will go down, and a new one will come down in it's place. My question is more in how I should set it up. I have my code to count the bet (in changing the text), just more confused on how to continue. How would yall think through this? If it helps, the bet can only go up to 7, down to 0. Please @ me if you respond, thanks!

[rich ice]

extremely basic way of doing it but i'd think something like this would work (repeat for the rest of the numbers too

int int1;
int int2;
if(int1 < 0)
{
  int1 = 7
  int2--;
  //rest of the stuff you want to happen
}

[rich adder]

Are you asking about animated digits or something? Confused there

[rich ice]

oh right yeah that too. if you're asking about animation then you should ask in #🏃┃animation

[cosmic dagger]

Are you asking how to animate it? If so, check out #🏃┃animation

[frosty hound]

I'm confused. Why is the script titled Checkpoint the one also tracking all the checkpoint transforms when the player collides with it, this doesn't make sense?

[green shale]

Don't know. My head is very saturated

I have tried many ways

[frosty hound]

Okay, scrap it:

1. Create a CheckpointManager which will have a new array of CheckpointController[] Checkpoints and int CurrentCheckpointIndex
2. Create a checkpoint object and give it the script CheckpointController
3. Give this checkpoint object its collider that the player has to hit to trigger the checkpoint save
4. Give this checkpoint a child object which is the spawn position transform and cache it as the Transform SpawnPosition in the CheckpointController
5. Drag each of your checkpoints into the Checkpoints array on your CheckpointManager in the order the player must hit them (assuming they can't skip one)
6. Do an OnTriggerEnter detection on your CheckpointController for the player hitting it. When it does, notify the CheckpointManager.CheckpointHit (this) function
7. In that CheckpointHit (CheckpointController checkpoint) function on your CheckpointManager, you can check if it's the same as the next element in the array
8. If it is, then you increment CurrentCheckpointIndex + 1 and when the player has to spawn, you can get the Checkpoints[CurrentCheckpointIndex].SpawnPosition.position

[hasty dragon]

how do i divide variable into different tabs?

to make them organised in the engine

[frosty hound]

You have to make your own custom drawer. Or you can use an asset like Odin Inspector which has built in [TabGroup] attributes

[hasty dragon]

how do i make a loop that loops every five seconds

[keen owl]

Coroutines

[rich adder]

you can also use update

    float time;
    float maxTime = 5;
    void Update(){
        if (time > 0){
            time -= Time.deltaTime;
        }
        else if (time <= 0){
            time = maxTime;
            DoSomething();
        }
    }```

[drifting cosmos]

what about async

[north kiln]

float _duration = 5;
float _nextTime = 0;

void Update()
{
  while (Time.time >= _nextTime)
  {
    _nextTime += _duration;
    DoSomething();
  }
}

I also like this method

there's lots of ways to do it and lots of caveats for each one. Async is also a method; be it Awaitable or UniTask

[rich adder]

you could just put a while loop in async task / awaitable to Task.Delay

[keen owl]

asyncs work with tasks and threads while coroutines yield execution of code at specific points

[north kiln]

async isn't on a thread unless you use APIs that do that

both are just state machines, async is just much more flexible (and has more caveats)

[keen owl]

I don't see why he would use asyncs in this scenario though unless he is working with APIs or file IO

[rich adder]

you could put non-unity apis in separate threads for heavy calculations

[north kiln]

it's just as viable as coroutines. We use it in loads of places

[drifting cosmos]

ive just heard that async is better than courotines

[keen owl]

hm that's interesting, never seen that before 👀

[rich adder]

is UniTask still useful now that we have Awaitable ?

[north kiln]

Awaitable isn't very mature, I've had teething issues with it

[rich adder]

last thing i'd want is a weird anomaly in async code lol

[drifting cosmos]

is this a true statement i dont think it is: When you create a prefab in Unity, you're essentially creating a template for a GameObject. Each time you instantiate that prefab, Unity creates a new instance of that GameObject. Each instance holds its own separate data for public variables defined in the script attached to that prefab.

[north kiln]

Yes it's true. Prefabs are an editor-only concept and everything is just instances at runtime

[rich adder]

if you put prefab in the scene that already creates the instance, Instantiate just clones that template yea

[drifting cosmos]

well like if you have a public variable and you spawn multiple objects you cant have different of the variable right?

[rich adder]

yeah each one have their own value of that var

[drifting cosmos]

i thought public variables were

like public

[rich adder]

public just means accessed from other classes

[drifting cosmos]

ohhh

so you coud calll like object1.speed and object2.speed

[rich adder]

if you made them static, now thats another story. Suddenly they all share the same value cause it belongs to the class itself not an instance

[rich adder]

yeah each one is a separate instance
as long as you have the reference

[drifting cosmos]

i dont know why people call public variables so dangerous then

[keen owl]

Unity serializes and deserializes component data when instantiating prefabs and something to keep in mind that each instance of a prefab does have it's own place in memory, so at runtime they aren't 100% tied together

[rich adder]

protecting from your future self or other collaborators

[drifting cosmos]

well i know about instances but like what if you have a class dog and a class cat with public speeds

[keen owl]

naming conflicts

[rich adder]

what about them ?

class is just a blueprint to what an / object will be . the instance is the created object

[drifting cosmos]

ok i think i get it

hm wait

[rich adder]

public class Dog {
public string Name; }

Dog myDog = new Dog();
myDog.Name = "Snoopy";
Dog yourDog = new Dog();
yourDog.Name = "Fido";

etc

[acoustic sequoia]

hey everyone, how do i do something like this correctly..

var upDirection = Vector3.up;
var otherLighterDirection = Vector3.right * 0.5f;
var combinedDirection = upDirection + otherLighterDirection;```
this doesn't seem to work...why?

[keen owl]

what doesn't work about it?

[acoustic sequoia]

let me answer by saying this...

why does this:

var otherLighterDirection = Vector3.right * 0.5f;
var combinedDirection = upDirection + otherLighterDirection;```

behave the same way as this:
```var upDirection = Vector3.up;
var otherLighterDirection = Vector3.right; <-- changed
var combinedDirection = upDirection + otherLighterDirection;```

[north kiln]

It doesn't, one is 0.5, 1, 0 and the other is 1, 1, 0

[acoustic sequoia]

no the combined direction is the same...

[keen owl]

not really, when you multiply the vector with 0.5 you are reducing it's magnitude essentially

the direction is the same, yes

[ivory bobcat]

The second:cs v1: 0.0, 1.0, 0.0 v2: 1.0, 0.0, 0.0 v3 = v1 + v2 v3: 1.0, 1.0, 0.0 The first:cs v1: 0.0, 1.0, 0.0 v2: 0.5, 0.0, 0.0 v3 = v1 + v2 v3: 0.5, 1.0, 0.0

[acoustic sequoia]

hmm. let mesee

[ivory bobcat]

If anything, when you normalize them you'll get a magnitude of one but they do differ.

[north kiln]

Shockly I'm not lying

[static cedar]

Is LayoutRebuilder.ForceRebuildLayoutImmediate recursive?

[static stag]

after the nice help yesterday, today smth new. Have to create a Grid for my Map editor, i thinking of drawing a "grid" sprite on top, but i dont like that solution. Does some one had a similar problem?

[crystal chasm]

Use the line renderer

And render lines...

[burnt vapor]

The only thing accessibility modifier or accessors do is restrict access

[keen owl]

in the literal sense, yes

[acoustic sequoia]

is there something wrong with this? everything else is working except this.. logging the removal never happens...

            foreach(var enemy in separationColliders)
                if(alignmentColliders.Contains(enemy)) {
                    alignmentColliders.Remove(enemy);
                    UnityEngine.Debug.Log("found enemy");
                }
                   


            return alignmentColliders;
        }```

[rich adder]

can't remove items from list during foreach loop, the collection is immutable there

[acoustic sequoia]

wth lol so how should i do it?

create a new list?

[rich adder]

you can use a reverse forloop and do the same

if your ide is configured type forr, hit tab

[acoustic sequoia]

yes that works.. why does the reverse work? if you don't mind me asking?

[rich adder]

because removing backwards doesn't mess with indices

if you go forward remove item it shift and can cause skip elements

foreach is just going through an enumerator so its expecting not to change (immutable)

[acoustic sequoia]

ahh ok thank you!

[mortal breach]

Hey, for what seems like the billionth time im trying to figure out Instantiate rotations, i just want enemy bullets to face the player when spawned but i cant get it to work, any ideas?

[keen dew]

need to see the code

[mortal breach]

One sec

Right now the instantiate is looking like this

references are set correctly

and the bullet has this

ignore the update

i tried to make it follow the player for debugging but still wouldnt work

[keen dew]

Using a position for LookRotation doesn't make sense, unless the bullets spawn at 0, 0.

Is this 3d or 2d?

3d apparently based on OnTriggerEnter

var bullet = Instantiate(Bullet, ...
bullet.transform.LookAt(M_Player.transform.position);

[mortal breach]

yeah 3d

oh i thought look at would do the math to look at the player

look rotation*

[mortal breach]

how's this any different?

[keen dew]

Different from what? The Quaternion.LookRotation?

[mortal breach]

having transform.LookAt inside the bullet

the thing i have in update

it doesnt work either

[keen dew]

In what way does it not work?

[mortal breach]

it seems to not effect it in any way

the bullets aim correctly up or down but not left to right

[keen dew]

I don't know what that means

[mortal breach]

Well damn me

[keen dew]

can you record a video?

[mortal breach]

Your code works

No idea why though

[verbal dome]

Do you understand the difference between a position vector and a direction vector?

[burnt vapor]

I'm confused why your editor marks these methods as unused when it knows they're Unity methods

[mortal breach]

i think so yeah

[burnt vapor]

That should not happen

[verbal dome]

LookAt requires a position as argument
LookRotation requires a direction as argument

[mortal breach]

ahhh

[keen dew]

You only set the velocity in Start so rotating in Update doesn't change the direction they're moving, so that's different at least

[mortal breach]

so in look rotation i would need sth like (spawnposition - playerPosition)

[verbal dome]

Yep!

Or wait

I don't know what's looking at what here

But it would be to - from

[mortal breach]

yeah, the negative of what i wrote

they would go the other way doing it my way lmao

[mortal breach]

this i still dont understand though

ohhh

now i get it

been a while since i worked with rigidbodies

So if i understand it right, LookAt rotates it but it still had worldspace momentum so it just kept going

[keen dew]

Can you tell visually which way the bullets are rotated or are you going by the movement only?

because movement and rotation are different things

[mortal breach]

i suppose if i slow them down i can

they are elongated along the z so yeah

[verbal dome]

FYI, using anything transform related on a rigidbody object will break your interpolation and also probably introduces some physics oddities

Like bad collisions

[keen dew]

In the original code they should have been always pointed towards the player but moving in a different direction

[mortal breach]

got it

[mortal breach]

its been a while as i said working with rigidbodies so i do produce some brainfarts

all this time the project has just been character controllers and navmeshagents

[verbal dome]

It's probably not too noticeable in this case since the bullets use triggers and don't rotate too much

[mortal breach]

so rotating through transform worked

well now they dont need to rotate at all, they spawn correctly

[verbal dome]

True

[mortal breach]

Oh and

this worked too

Thanks so much people, you've been really helpful once again!

[brisk echo]

Hi, I was wondering if the 'proper' place to put CharacterController.Move() should be in Update or FixedUpdate?
My understanding is that physics movements should be in FixedUpdate but I'm finding if I put it in there I'm getting jittery jumping and side-stepping.
Thanks

[verbal dome]

CC is an exception, it was designed to work in Update

[brisk echo]

Ok thank you. Does that mean things like where I'm altering the gravity in FixedUpdate for it should be moved back to Update due to CC.Move() being done in Update?

[verbal dome]

Yeah makes more sense to do it all in Update

Remember to swap out fixedDeltaTime to deltaTime though

[echo ruin]

Typically you’d use fixed update if you move things with physics. I.e. the object had and uses a Rigidbody

Yeah what Osmal said

[brisk echo]

Will do. Thanks 😊

[echo ruin]

Probably wouldn’t have movement in both Update and Fixed update though

[brisk echo]

Ah of course. Guessing because CharacterBody isn't using a rigidbody that's why it goes in Update typically.

[brisk echo]

Thanks. Gonna shift it back into Update.

[echo ruin]

Do you just move using the transform?

[verbal dome]

cc.Move does the moving

[brisk echo]

CharacterController.Move() is doing the movement. Am updating the transform for rotation.

[echo ruin]

👍

[wooden nacelle]

can someone tell me how can i see logs for each of my builds??

[timber tide]

It still probably moves in fixed update as it's unnecessary to continuously calculate in update so what it probably does is buffer those values.

rather it probably uses its own internal fixed loop instead of the one that rigidbody relies on

[wintry quarry]

All the info is here under "Player Related Log Locations"
https://docs.unity3d.com/6000.0/Documentation/Manual/log-files.html

[wooden nacelle]

i got it thanks!!

[hasty dragon]

why are the blue

the logs

theyre usually grey

[burnt vapor]

Because you selected it

[hasty dragon]

left in unselected

right is selected

how do i do random.range

but with integers

[burnt vapor]

Use the overload that uses integers

One for floating point, one for integers

[buoyant finch]

hello how to make a player move based on the grid pls someone help

[silk night]

That question is way to broad, this sounds like you should watch basic videos on scripting

[buoyant finch]

I did but it introduces some new errors in my script because my player is very complex

[ivory bobcat]

Lookup a youtube tutorial on grid base systems

Integration is part of the development cycle - bugs/unwanted-behaviors.

[buoyant finch]

I did but nothing too useful

 void HandleInput()
 {
     // Get input
     float horizontal = Input.GetAxisRaw("Horizontal");
     float vertical = Input.GetAxisRaw("Vertical");

     // Prioritize vertical movement to prevent diagonal movement
     if (vertical != 0)
     {
         movement = new Vector2(0, vertical).normalized;
         lastDirection = vertical > 0 ? "Up" : "Down";
     }
     else if (horizontal != 0)
     {
         movement = new Vector2(horizontal, 0).normalized;
         lastDirection = horizontal > 0 ? "Right" : "Left";
     }
     else
     {
         movement = Vector2.zero;
     }

     // Check if running
     isRunning = Input.GetKey(KeyCode.Z);

     // Move the player
     float speed = isRunning ? runSpeed : walkSpeed;
     transform.Translate(movement * speed * Time.deltaTime);

     // Check if player is walking
     isWalking = movement.magnitude > 0;

     // Reset key press mode when no movement
     if (!isWalking)
     {
         keyPressMode = true;
         keyPressTimer = 0f;
     }
 }

this is my movement rn

my player basically has variable speed and can wander off the grid

[ivory bobcat]

Why use strings?

[buoyant finch]

Yeah so basically in my game I want to make the player face a position I type in

[supple salmon]

What are you actually trying to do?

[buoyant finch]

to make the movement grid based as right now the speed is variable and can wander off grid

[supple salmon]

If you mean that you want your player to be able to specifically travel just between squares in the grid, then I'd say the simplest way would be to Lerp between grid locations

[buoyant finch]

so I need to make changes in the handleinput only right?

[supple salmon]

I'd put it in an IEnumerator, but if HandleInput() is called from the Update() loop then you could make it work that way

This is a good resource on Lerping for beginners: https://gamedevbeginner.com/the-right-way-to-lerp-in-unity-with-examples

[buoyant finch]

thx a lot

[rapid laurel]

hey guys im trying to resolve a problem i had yesterday and still cant fix it,
my character bullet only moves to ONE direction when i shoot to right or to left depending if i use the transform.right or -transform.right.

My class CharacterController have the boolean loookingRight, it switch to true or false depending on the direction my character object is looking.
So i tried to fix it by making this boolean atribute public, and creating a public CharacterController in my BulletController Class who determinates the direction of the bullet and the speed.

Then i added the object in the Inspector.
And made a condition: (mirandoDerecha its the same as lookingRight)

if (!playerController.mirandoDerecha)
{
direction = -transform.right;
}
else if (playerController.mirandoDerecha) {
direction = transform.right;
}

rb.linearVelocity = direction * speed;

and all this doesn't work, I don't understand why, if someone who has more programming logic than me knows something I would appreciate it!!

[keen cargo]

have you tried += for the direction assignments?

because certain rotations need to be added to your current rotations in order to make them rotate

[frigid sequoia]

If, lets say, I am trying to get a reference to an script that has been destroyed, that's not the same as null right?

[smoky river]

why can't i move my character? is it a problem with the code or?
here is the code:

using System.Collections.Generic;
using UnityEngine;

public class movement : MonoBehaviour
{
    [SerializedField] private float speed;
    private Rigidbody2D body;

    private void Awake()
    {
        body = GetComponent<Rigidbody2D>();
    }

    private void Update()
    {
        body.velocity = new Vector2(Input.GetAxis("Horizontal") * speed, body.velocity.y);
    }

}```

[frigid sequoia]

Like this is not null right?

[grand snow]

it will equate to null but wont really be null
But if thats in edit mode it means the reference is just broken and should be null at runtime.

[frigid sequoia]

This is relevant, I am specifically searching for nulls, since it would only search for a new one if it's null

[grand snow]

then yea it will == null

[keen cargo]

yes it's a problem with your code

[smoky river]

may i know what the problem is

[keen cargo]

yeah one sec

so it's within the Update() part

it's not how you work with rigidbody.velocity, it just needs a direction and then the movespeed

you have some kind of.. other thing going on

[smoky river]

im following a 4 year old tutorial so maybe thats the problem?

[keen cargo]

naw it's not the age of the tutorial, it's how the function works

[smoky river]

well it works for the guy but not for me 😭

[keen cargo]

maybe it could work, have you put the script on the object that you want to move?

[smoky river]

yeah i think

[keen cargo]

and have you changed the speed variable in the inspector

[smoky river]

i just have to drag and put it on the right after selecting the player right

[keen cargo]

i mean yea

[smoky river]

i don't think i did

[keen cargo]

as long as it shows up on your inspector

[smoky river]

it doesn't show up

[keen cargo]

i see why, you don't need the private after [SerializeField]

[SerializeField] already is innately private

you're basically doubling down on the private

[smoky river]

even after i removed private

[keen cargo]

you have an extra d in there

[SerializeField]

[smoky river]

oh damn

[keen cargo]

also was that error there before

[smoky river]

what do you mean by before

like how before

[keen cargo]

when you first asked about your issue

[smoky river]

yeah

the movement still doesn't work btw

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

public class movement : MonoBehaviour
{
    [SerializeField] float speed;
    private Rigidbody2D body;

    private void Awake()
    {
        body = GetComponent<Rigidbody2D>();
    }

    private void Update()
    {
        body.velocity = new Vector2(Input.GetAxis("Horizontal") * speed, body.velocity.y);
    }

}

how much am i supposed to set the speed as

[keen cargo]

and do you have anything in the inspector

[smoky river]

speed popped up now

[keen cargo]

now change that

[smoky river]

should i set it at a certain value

[keen cargo]

it's for you to test

[smoky river]

YOOO

it works now

thank u sm

[keen cargo]

np, btw pay attention to the errors they will tell you a lot

[smoky river]

but how did the dude in the tutorial still do it even if he put [serializefield] private

[smoky river]

yeah but the problem is i don't understand them 😭

[keen cargo]

honestly it might still work even with the private keyword just fine

it's just that private is unnecessary

your core issue was that it was a typo

well lets look at your error again

Type or namespace name "SerializedField" could not be found

it just means that it doesn't know what the hell it is

[smoky river]

i thought it was some computer thing i don't understand ts bro

[keen cargo]

you can usually ignore the address and the code number (address is useful if another script is giving you the issue so you know where to look)

[smoky river]

oh alr

thanks

[keen cargo]

what IDE are you using?

because it should have flagged you the typo in your [SerializedField]

like so

[smoky river]

whats an ide

im using visual studio

if thats what u mean

[keen cargo]

that's your IDE

coding environment basically

[smoky river]

oh ok

[keen cargo]

is it visual studio CODE or visual studio COMMUNITY

[smoky river]

what are the best ides

[keen cargo]

visual studio CODE is with the blue logo

COMMUNITY is the purple one

[smoky river]

purple one

[keen cargo]

ok so you have the best one

[smoky river]

are there any better ones

[keen cargo]

it's up to personal taste really

i use community myself, because it's just pretty versatile and I can do c++ coding

and most people use community here as well

[grand snow]

its VS and VS code

[smoky river]

i hate c++ with a passion

[grand snow]

community is just the free version of vs

no one likes cpp we just put up with it

[smoky river]

anyways finally my paracetamol moves

[keen cargo]

eh yeah tomato potato

[keen cargo]

do one thing for me, send a screenshot of your code with the [SerializeDField] typo

lets see if it flags it

[smoky river]

do i have to save it or no

[keen cargo]

no it should do it automatically

you should see it basically immediately

like this

[smoky river]

it doesn't

[keen cargo]

ok something's up with your visual studio, you may need to do some setup

Visual Studio guide

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

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)

[keen cargo]

you want it to flag mistakes like these or else you're going to waste a lot of your time asking and waiting for answers

[smoky river]

whats the fastest way to do it

[keen cargo]

use the links

[burnt vapor]

You're also required to have a properly configured IDE to be helped

[smoky river]

cuz i gtg in a bit

[burnt vapor]

Takes 2 minutes if you know what to look for

2 steps, maybe three. You have to download a workload if you installed VS manually which can be sizey

[smoky river]

when installing vs community i already did the unity thingy but now in unity hub theres no add button in the install

yeah im doing ts tmrw its hurting my brain

[hasty dragon]

how do i select the function i want

[grand snow]

er do you have debug mode on?

[hasty dragon]

no

im on unity 6

[frosty hound]

The animation event has to be on an animation clip, while you have the object selected in your scene that has an animator controller with this clip on it.

Also you need to actually start learning the basics of Unity instead of posting questions here every few minutes.

[hasty dragon]

why is it not supported

[hasty dragon]

oh

okay

[frigid sequoia]

Guys, I am suprerusty, how was that, I add stuff to the Update method of a child class without replacing the superclass one?

[naive pawn]

you don't; you just call the superclass one as well

override T SomeMethod() {
    base.SomeMethod();
    // own logic
}

you can't if the method is private, however

but i would maybe reconsider that hierarchy

[frigid sequoia]

How was to make it only redeable by childs?

protected?

[naive pawn]

yes

[naive pawn]

what line is it coming from?

[hasty dragon]

17

[naive pawn]

i don't know what line 17 is there

[hasty dragon]

oh sorry

gamelogic.health -= 1

the last one

[rich adder]

so gamelogic is null

[grand snow]

then gamelogic is null isnt it?

ops you have gameLogic and gamelogic 😐

[rich adder]

you never actually check the local var

also what is even the point of that public var

[naive pawn]

the other object in the collision doesn't have a GameLogic then

[frigid sequoia]

What is causing this? I have no compile errors. It's cause it's not using the MonoBehaviour?

[rich adder]

do you have compile error?

if not try Reimport the asset, right click it -> Reimport

[cosmic dagger]

Null reference error means a reference type variable is not assigned or its value is null

Look on the error line to search for all reference types—one by one—and check if they're null . . .

[hasty dragon]

yeah i found the issue

but i have another problem

i tried every gameobject in my game

[cosmic dagger]

What type is GeneralistAbilityManager?

[hasty dragon]

all of them are mistaches

[rich adder]

You cannot drag scene objects in here

asssuming this is a prefab

[rotund osprey]

Hello! I'm trying to follow a Unity Learn tutorial and things are working okay so far but I'm having trouble getting the hierarchy and properties window to show an updated part of the script, instead it only shows 1/2 properties despite being both classified as public. I've done something wrong or it's not refreshing. I have to go afk for a while smh

[hasty dragon]

oh it is, then what do i do?

I know you found the issue. I'm explaining how to look (search) for the variable with the error . . .

[rich adder]

btw those aren't properties, they are fields. A bit of a difference

your changes seem unsaved

unsaved color

[frigid sequoia]

It is Monobehaviour if that's what you are asking

[frigid sequoia]

I stated that, no, I have none

[rich adder]

try reimport then, this is used to happen to me when I created a new script on prefab, it was bug for me

had to trigger a recompile basically

[proper flint]

sometimes either reloading, or creating a new script and copy pasting the content of the old one, helps.

[frigid sequoia]

So it's just Unity being weird?

[proper flint]

ye

[swift crag]

It may have missed a file change

See if the text displayed in the inspector for the script asset matches the contents of the file

[rocky canyon]

if i disable Directory Monitoring i don't really need to worry about Refreshing correct?
like when i go into playmode it should all update?

trying to speed up my editor just a tiny bit.. i dont really wanna do the Full Domain Reloading thing.. but i found out about this directory monitoring.. wonderin if its useful?

[astral falcon]

oh, windows only, explains why I have never seen it 😄

[rocky canyon]

oh really? TIL

[hot laurel]

You can only disable Domain Reload for Entering Play Mode.
In other cases the domain is always reloaded when source script asset change and its trigged by AssetsDatabase.Refresh

[astral falcon]

What you speed up is the check for changes, the event will get fired anyways

[hot laurel]

so if you disable directory monitoring it will probably still enumerate whole directory and compare against stored timestamps on unity window focus

[meager raven]

does anybody know a really simple way to move the player in 2d unity?

ive been looking for a while and i get way too confused

[astral falcon]

Did you like try anything yet? 2D Tutorials form unity learn for example?

https://learn.unity.com/course/2d-beginner-adventure-game

[meager raven]

mainly just youtube videos for now, but ill try this out. thanks

https://learn.unity.com/learn/pathway/unity-essentials

[meager raven]

thanks alot guys, ive been stuck on this for a few days

[rocky canyon]

from what i understand if i leave Auto-Refresh on.. and Directory Monitoring unticked..

then the changes are updated on their own.. but applied to the project when Ctrl+R (Refresh) is pressed

but then again.. im not fully versed on this part.. I'm more familiar with domain reloading. and how that works.. but not the auto-refresh and directory monitoring

[astral falcon]

I think, its two parts, not one with two variants. THe one is the detection of the changes, which can be auto or manual and how it detects them, via directory or files. And the second part is the actual reloading in unity, the domain reloading to be able to test them. Thats how I understand those settings

[rocky canyon]

well these two options were found under Preferences

domain reloading under ProjectSettings

so. in my head they were different from each other

[astral falcon]

Thats what I meant. THats two parts of the asset handling

[rocky canyon]

but i do know i dont wanna worry about domain reloading and whatnot..
sounds too much for me dealing with static classes

and initialization stuff

Assembly Defs may be a middle ground

[astral falcon]

Uh I would not ever turn off domain reloading after reading this 😄 https://docs.unity3d.com/6000.0/Documentation/Manual/domain-reloading.html

[rocky canyon]

so in my head the way i think of it.. the first image is the Directory:

• this means the progress bar that progresses when going from IDE to editor.. or minimized editor to focused editor
  then the other settings are to do with PlayMode:
• this means the progress bar that progresses when going into PlayMode from EditMode

thats my starting generalization anyway..

[rich adder]

its pretty much fine

how often you really mess with static vars ?

just be mindful to reset those

if you use static events, clean them up

the time you going in and out of play is wasted time lol

[astral falcon]

but the list what happens when turned off sounds to be like a good source of failure when observing and debugging things.

[rocky canyon]

yea, here lately i've been doing little to-do lists.. ALL before entering playmode

im pretty sure its saved me more time than i can imagine

used to every little change i made i'd play-mode..

[astral falcon]

haha yeh, you get used to write bunch of code before even testing

[rich adder]

yet to have an issue after 5 years of it off but who knows 🤞 I'm just one person

[rocky canyon]

i like the new name navarone 👍

[rocky canyon]

oh no no.. not like that 😄 just iterations

never will i make a new script fully before testing along the way

[rocky canyon]

ahh, that makes me a bit jealous.

[rich adder]

oh one time i had issues was some assets were not mindful of Domain Reloading being off with some people
(but the devs quickly patched the SDK after it was brought up)

[rocky canyon]

i may try to incorporate it into my work-flow

but then again i may experiment with assembly definitions.. and see how that works out

[rich adder]

if you use lots of third party assets you might have issues if oirignal asset maker didnt account for Domain Reloading being off

[astral falcon]

haha no, I am fully aware thats a me issue 😄 I just never had the time yet to really try it out in a project and was jsut scared reading the list. But i guess, once established, it might just be fine

[rich adder]

took me a while to fully trust it, and like I said I don't use many third party assets that have scripts so less of a chance for me something going haywire

[rocky canyon]

ya, it is a tad scary.. especially for someone like me

[rich adder]

ironically the new unity 6 multiplayer player mode testing thing didnt like Domain Reloading off and threw weird bugs, I heard unity patched it since.. Idk I use ParallelSync which works fine with Domain Reload off

[astral falcon]

so you feel me here 😄 I just read "no additional OnDisable and OnEnable" calls and already felt like, dang, this can confuse me already when trusting those methods 😄

[rich adder]

yeah true, I'm used to them, I used those anyway cause always got paraoid for leaked events but turns out its only issues with static mostly, still good practice too

[dreamy wren]

can someone help me with this code im newer and need some help, what do I put so when I press M all movement is stoped for a set amount of time?

[rocky canyon]

ah mb.. i just realized i wanted to discuss this in Unity-Talk.. mb im finished tho.. thanks for the input guys 🙏

[astral falcon]

[stone glen]

hi everyone, How can I move a player from a box to another box?

ok i will try thx

[rich adder]

so whats wrong?

aside from horrid formatting lol

Oh you want to stop all movement when pressing M ?

[dreamy wren]

yes please

[rich adder]

create a bool that is tied to the M key, if its true return out of the move input capture or return out rb.MovePosition (only do this if you need complete stop)

[dreamy wren]

how do I make a bool?

[rich adder]

declare it in your script

just like you had declared the other variables

declare : bool isPressingStopKey
usage : isPressingStopKey = Input.GetKey(KeyCode.M);

if(isPressingStopKey) return;
//stuff here only happns if isPressingStopKey == false```

only whats underneath

[rocky canyon]

clearly u need to organize it in a way tha works

[rich adder]

ugly nesting prevention

[rocky canyon]

dont early return at teh very top for no reason..

[rich adder]

early return pattern ftw

[rocky canyon]

it just depends on the use-case

[rich adder]

You can also put it in a method inside Update to not disturb Update

[rocky canyon]

but its way superior to long-nested if/else statements

"go home early today"

[rich adder]

game canceled, heavy snow

[rocky canyon]

grandpap and ma will disappointed

no..

[rich adder]

you shouldn't actually

[rocky canyon]

do Move() in update

[rich adder]

CC should be moved in Update

[rocky canyon]

its built to handle it..

[rich adder]

Rigidbodies should be in FixedUpdate though

[rocky canyon]

that sorta kinda tho

i still set velocities in update to match my inputs

[rich adder]

CC is like a weird kinematic controller that Nvidia Physix has made unity just adapted the api

[rocky canyon]

u can set velocity every frame..
it'll still only get applied on the appropriate physics tick

but.. be mindful ofc

[rich adder]

wait wdym

[rocky canyon]

if im using a rigidbody.. theres times i'll still put rb.velocity = input; in the update loop

it'll still only get applied on the next physics tick..

soo its still possible

[rich adder]

ohh what does that do though instead of putting in fixed?

isnt Input already captured in Update anyway

[rocky canyon]

private Vector3 targetVelocity;
private Rigidbody rb;
void Update()
{
    float horizontal = Input.GetAxis("Horizontal");
    float vertical = Input.GetAxis("Vertical");
    targetVelocity = new Vector3(horizontal, 0, vertical).normalized * speed;
}
void FixedUpdate()
{
    rb.velocity = targetVelocity;
}``` and
```cs
void Update()
{
    ...
    targetVelocity = new Vector3(horizontal, 0, vertical).normalized * speed;
    rb.velocity = targetVelocity;
}``` will function the exact same

but it is based on what ur doing and how ur doing it ofc..

[rich adder]

I had weird results at different FPS when using Raw in Update, so I used GetAxisRaw in FixedUpdate and fixed the inconsistent speeds

[rocky canyon]

something simple as this.. (no worries)
something a little more advanced (with multiple forces possibly external forces) maybe not

[rocky canyon]

i use Raw too.. ide prefers GetAxis tho 🤣
i just autocomplete tabbed that entire code

[rich adder]

ohh I usually do
rb.velocity = inputs * speed
in FIxedUpdate
idk if that matters

[rocky canyon]

ya, like the first example..

thats probably the most proper way tbh

Input in update
applied in fixed

[rich adder]

applying speed in fixedupdate vs update does it matter ? lol its been a while since I did those small test

I dont even use Update anymore for inputs thats why

new input system is event based

no polling

[rocky canyon]

its because u can set the velocity of the rigibody in update as many times as u want...
it really wont matter until the fixedupdate runs.. (then w/e value is there At that exact moment will be used)

[rich adder]

I think it doesnt matter because the rigidbody velocity doesnt deal with mass and forces

[rocky canyon]

but yea.. for most cases for rigidbodies u want to be doing the actual logic in Fixed..

but u can get away with simple stuff in

[rich adder]

but for AddForce you probably do want FixedUpdate for sure

[rocky canyon]

thats true too

u could ya..

Dotproduct maybe?

[night mural]

this looks like a job for ✨ dot product ✨

[rocky canyon]

💪 nailed it

[night mural]

but yeah angle would probly work fine too

[rocky canyon]

u'd get teh smallest angle

closest angle to zero i believe.. it could be the opposite but yea look into Angle functions

  Vector3 towardsObject = (obj.transform.position - viewer.position).normalized;
  float angle = Vector3.Angle(viewer.forward, towardsObject);```
```cs
        Vector3 towardsObject = (obj.transform.position - viewer.position).normalized;
        float dot = Vector3.Dot(viewer.forward, towardsObject);```

i believe Dot is faster than Angle

"if this object is more aligned with the viewers forward direction"

[void thicket]

Angle is dot product with some more calculation to convert it as angle

[rocky canyon]

ahh okay 👍 that makes sense

i was just reading up on it..

[swift crag]

acos(dot(a, b)) is the angle, assuming that a and b are normalized

[void thicket]

Then Rad2Deg

[swift crag]

The angle is ideal if you want a linear response -- e.g. 30 degrees is exactly twice as far off as 15 degrees

the dot product is the cosine of the angle, so 0.9 -> 0.8 takes a different amount of rotation than 0.8 -> 0.7, for example

[rocky canyon]

i heard someone say once u could optimize it even further using a Cosine threshold.. or something like that

[swift crag]

you could take the cosine of an angle to get the threshold for your dot product

so that you aren't computing acos every time to get back to an angle

[rocky canyon]

but tbh im not too sure about it b/c my geometry isnt that strong

[rocky canyon]

yes this exactly!

is this Trig or Geometry?

oh nevermind 🤪

[void thicket]

Linear algebra

[rocky canyon]

lmao touche

[frigid sequoia]

Is there a way to stop just the Update method of a script for a while?

[rocky canyon]

wrap its contents in a boolean

or an early return with a negated bool

[frigid sequoia]

Mmmmm, ya makes sense

[rocky canyon]

    void Update()
    {
        if (!proceed) { return; }
        wasGrounded = characterController.isGrounded;

        ProcessPlayerInput();
        GroundCheck();
        JumpCheck();
        Move();

        GetPlayersSpeed();

        if (!wasGrounded && characterController.isGrounded)
        {
            headbob.CamRebound();
        }
    }```

[frigid sequoia]

So if proceed is false it would just skip the rest of the update right?

[rocky canyon]

yup

[frigid sequoia]

Cool

Pretty much what I want

[rocky canyon]

u could disable the script entirely for a bit..
but that may not be viable in ur situation

[astral pine]

Hi! I've been trying to use my camera feed on mobile but it doesn't overlap with what my actual camera feed looks like. It's more zoomed in than it should be and thus when I click on the screen it takes the info from my actual camera feed. Due to this it's inaccurate.

[rocky canyon]

not sure i understand exactly what ur saying.. but if its to do with UI and the canvas u need to make sure its scaling and set correctly...

[astral pine]

Yeah I've been trying that but the raw image remains zoomed in compared to my actual camera feed

[night mural]

where's your 'actual camera feed' coming from? just the camera app?

[astral pine]

Yeah

I look at it to compare it and the input unity gets touchscreen wise is from the actual camera feed. I'm trying to make a thing so that you can click on the screen and it shows you the color it is. But it doesn't use the raw image camera feed you see

[rich adder]

if your camera has multiple lenses most likely you selected the one that has zoom/telephoto lens

[astral pine]

Oh that makes sense. How do you select the right one in your code then?

[night mural]

yeah that's what I'd guess too, there's probably some option you need to set

[rich adder]

are you looping through the available devices ?

[astral pine]

Not sure I understand. I'm just using my own phone which is connected with an USB cable

[rich adder]

are you using WebCamTexture ?

[astral pine]

yeah

[rich adder]

ok so if you are, then you have the available devices

[astral pine]

Alright

            Destroy(gameObject);
        }
    }
}

this is bulletscript

[cosmic dagger]

hard to tell bc from your images it's not . . .

[rotund osprey]

is this configured

[cosmic dagger]

do both objects have a collider. does at least one object have a rigidbody?

[echo kite]

wym both

OHHH

[cosmic dagger]

that just means the script editor is set . . .

[cosmic dagger]

huh? what does the bullet hit (collide with)?

[echo kite]

it hits wall but wall has collider

[rotund osprey]

these are the exact instructions

[rocky canyon]

heres how u could easily tell if it is or not

[rotund osprey]

idk how to then

[rocky canyon]

yes we know.. its just a step of the process

[cosmic dagger]

it says miscellaneous files in your IDE. this means it's not configured. did that change to your project solution?

[cosmic dagger]

this is only one part of it. there should be more than just this step . . .

[cosmic dagger]

show us the inspector for the bullet . . .

[rocky canyon]

sometimes u may need to restart, atleast the IDE once u do the other steps to make sure its working
along w/ sometimes needing to regen project files

[rocky canyon]

is there a collider?

[echo kite]

yes u can see it in screenshot

[cosmic dagger]

uhhh . . . where's the collider?

[echo kite]

rigidbody

[rocky canyon]

i must be blind..

thats not a collider

[cosmic dagger]

a rigidbody is not a collider . . .

your wall GameObject has a Collider. does that make it a Rigidbody? no . . .

[echo kite]

ty i fixed it

i thought all mesh had it before

[cosmic dagger]

you can easily tell by looking for a Collider component on the GameObject . . .

[rocky canyon]

nah.. if its a mesh it can have a mesh collider

primitives usually do come with a collider tho..

Create > Cube, Sphere, Etc

[frigid sequoia]

If I Destroy a gameObject that was part of a List, although it essentially becomes null, it's still part of the List and therefore counting for stuff like .Count right?

[naive pawn]

yes, the list doesn't care what the stuff inside is

[frigid sequoia]

Mmm... that kinda makes annoying for me

But okay

[keen cargo]

I mean you could call the list counting every time something's destroyed

So the list counts what actually exists even if you destroy stuff

[frigid sequoia]

Yeah, just that getting a reference to the actual List is like 6 script jumps lmao

[keen cargo]

[frigid sequoia]

And it's part like for 3 different lists

[naive pawn]

you could make it managed, instead of Destroying the gameobject, you tell the script that owns the list to remove it, and that handles both the Destory and the Remove

oh

well, that could be difficult.

[timber tide]

keep wrap it in a struct with the list ref ;)

[frigid sequoia]

Could I like... get a reference to a misisng script?

[cosmic dagger]

why is it a part of three different lists?

[naive pawn]

can you clarify what you mean by "missing script"

[frigid sequoia]

Like if I get this, can I get it from there and remove it from all lists that may be in, although it's not there anymore?

[naive pawn]

when that happens it means the serialized reference is still there but the thing it's pointing to isn't

[cosmic dagger]

how can you retrieve somethig that is not there?

the reference itself will be null . . .

[frigid sequoia]

So, this works like this. I have a reference to all present entities on the scene, stored on an empty on top of all. All entities get the reference of what they should be targeting from there. But then, for example enemies, each have 2 Lists that basically derivate from the other, a List of HeavyAggroPlayers and another with all the rest, it would always try to get their target from the HeavyAggro first. I would have to remove it from the top of the List and make sure it's not present on any of the other Lists that each enemy has

Could I just iterate the list in search of nulls to remove them?

To much to check each frame I would say

Could I check for specifically a missing script rather than a null, so I can update the List only then?

[timber tide]

you can iterate and clear nulls but you gotta ask yourself when do you do that

best way to handle it is remove it from the list when you destroy it

[naive pawn]

you could use OnDisable or OnDestroy on the thing being destroyed
but i think it'd be better to handle it from the list side

[cosmic dagger]

as Mao suggested, you should/can update the list when an enemy is destroyed . . .

[frigid sequoia]

Yeah, there is no way EVERY enemy has a reference of what just died to remove from their lists specifcally

[naive pawn]

then those enemies can ignore that

[frigid sequoia]

It would be too demanding

[timber tide]

Some ideas is don't let the object destroy itself but use a manager type system to handle it, another is wrapping it in a struct with a list of lists that it is occupying. Or, just make a variable on the object itself that has references to all lists that it's included into and iterate through those on destroying.

[cosmic dagger]

i would use events to trigger the update . . .

[frigid sequoia]

Ok, I think I know how

[timber tide]

Best case -> events

or some subscription service to alert all lists that it's been destroyed at object level

really direct references are fine too... it's just events are fancier and encapsulates it a bit more tightly

[frigid sequoia]

The aggro manager checks first for the heavyAggroPlayers, then for all the rest, but will be stucked trying to get it from the List that just contains a null cause it sees it as containing something. I am gonna make so if after checking the lists it still has a null target, to just update the list, since something was clearly removed

[naive pawn]

but will be stucked trying to get it from the List that just contains a null cause it sees it as containing something
you could just make it check for null right there

[cosmic dagger]

wait, do all enemies have the same list of aggro players?

[naive pawn]

im not saying that's a bad solution; but the cause you mentioned is not really a problem

[frigid sequoia]

No, it's different for each one, pretty much they all know the players are there, but who they consider a priority is different for each one

[frigid sequoia]

It can totally be null at this a point, that's something that can happen, the heavyAggroTarget List may be totally empty

That's fine

This is what I am doing rn, so u can visualize it better

[cosmic dagger]

i thought the enemy has two lists: one aggro and one regular? how come you check listOfEntities.PossiblePlayerGroupsTargets?

also, did you try using events? i can give an example . . .

[frigid sequoia]

Oh, ya, possiblePlayerGroupsTarget is basically straight up gotten from the main reference, since it's basically everyone, but the other is specific to the enemy

Also, I have absolutely no idea of how to manage events

[cosmic dagger]

oh, i thought the enemy stored both lists itself? wouldn't the list on the main reference also contain players from the aggro list?

[frigid sequoia]

It does contain all active entities, whenever one is missing, it's removed

[swift crag]

You could skip over invalid targets and make a note that you need to prune the list

[night mural]

yeah I haven't read all the context but I often suggest solving this kind of thing by not deleting stuff so that there are never any nulls. Like if the problem is 'dead things need to be removed from everyone's target lists' you could reframe that to 'everyone's target list should handle the possibility that there are dead things in there' and that way 'cleaning up those lists' becomes its own task and you can do it whenever you want (this is basically garbage collection)

[swift crag]

indeed

i've been dealing with this on my own -- I have a lot of places that care about lists of Entities, and outright destroying them means I need to either:

• immediately stop tracking them (which could cause concurrent modification problems)
• check every entity object before trying to use it

[frigid sequoia]

Actually this one line seemed to do wonders

[swift crag]

I wonder if I should have a "cleanup step"

instead of immediately firing EntityManager.OnRemove, I would do that near the end of the frame

[night mural]

a long time ago I found that 'have corpses' solves a lot of these problems in a way that feels intuitive

[ripe shard]

looks like you're modifying the list you are enumerating

[swift crag]

yeah

a dead entity is still an entity

[night mural]

and may even be valid for some things to target!

[swift crag]

even an entity whose physical form has been mega-deleted may still "exist" in the form of memories, relationships, etc.

[ripe shard]

this maybe one of the most important "secrets" one has to figure out as a gamedev

[frigid sequoia]

I meant this one, sry

If iterating through the List I see a null I remove it straigh up

[night mural]

shouldn't that yell at you for removing while iterating?

[swift crag]

oh no, I'm discovering mind/body duality via unity

[ripe shard]

also you often find that you want to keep it around just as a container for effects, event limiting and obviously, pooling

[night mural]

Entities?
Spirits*

[ripe shard]

yeah, dont do that

if you want to remove stuff from a list while iterating, use a regular reverse for loop, not a foreach

[night mural]

if your method starts with 'Calculate' it should have no side effects imo

[swift crag]

yeah

[night mural]

finding the closest target and keeping the closest target list properly updated are different concerns

[swift crag]

genuinely thinking about creating a non-MonoBehaviour "soul" object that gives an identity to the Entity's physical body now

[frigid sequoia]

I could do it outside the method before calling it, but... kinda.... why? Is gonna do pretty much the same loop

[swift crag]

modifying a list while iterating over it will cause an exception

[ripe shard]

because they are different concers as prakkus said, and have entirely different reasons to be modified down the road

you should not have nulls in that list anyway, looks like a code smell to me

[swift crag]

well, they aren't really "null"

they're destroyed unity objects

[ripe shard]

well, then you need to observe that destroy event, not be surprised by it

[night mural]

I'm here for it! It'll be perfectly confusing in my game about cleaning troubled souls in a graveyard

[cosmic dagger]

https://paste.mod.gg/sgwmggejzrlt/0
here is an example with events. nothing is tested as i just made it up . . .

[swift crag]

Can't be any worse than whatever this class does

[frigid sequoia]

It is not causing it, it would seem

[night mural]

this isn't even my final transform

[night mural]

maybe there actually are no nulls so it's never happening?

[frigid sequoia]

Well, I am actually getting some exceptions, but it's working

[cosmic dagger]

@frigid sequoia the other site doesn't have context highlighting . . .

can somebody tell me why it don't collides

[rocky canyon]

how u moving it?

transform.position = ?

[vocal wing]

yes

im not using rigidbodys

[rocky canyon]

well, that's y it doesn't collide

[vocal wing]

anyway to collide with transform.position?

[rocky canyon]

https://www.youtube.com/watch?v=tNtOcDryKv4 no.. not w/o custom detection

[night raptor]

that question does not make much sense but no, transform.position teleports the object, the physics system then tries to fix the collisions based on the new position but it won't work very well

[vocal wing]

oh I see ty

[night raptor]

Especially if you are every frame overwriting the positition, the physics can do very little to prevent that

[astral falcon]

what are you doing?

[cosmic dagger]

The GameObjects must have colliders, and then you use physics methods to check for collisions. Basically, you do your own custom collision detection because manipulating the transform does not involve the physics engine . . .

[astral falcon]

With this I mean, show the actual code 🙂

[vocal wing]

I understand it now im changing it

[astral falcon]

only the positioning. In what method and how

is it a 2d space overlay canvas?

[verbal dome]

Maybe you are moving the camera every frame, after doing that?

[cosmic dagger]

This was an example of using events. The player script would have the event on it. The GameManager and Enemy scripts subscribe to it (the event). When the event is invoked, the methods attached to it are called (+= Player_OnDestroyed). They remove the player from the list on those scripts . . .

[daring oasis]

Vector3 cursor = Input.mousePosition;
cursorPos = mainCamera.WorldToScreenPoint(cursor);

why does cursorPos return valuez such as (-4371.42, -12528.05, 10.00)

[polar acorn]

Try logging cursor first, and see if that looks more like a screen position or a world position

[daring oasis]

i should also mention that mainCamera [SerializeField] Camera mainCamera;
is asigned to the main camera

[daring oasis]

i tried and it is a screen position

[naive pawn]

read the function you're using. you're taking the cursor as a world position
you need ScreenToWorldPoint

[polar acorn]

So, why not use Screen to World?

[verbal dome]

So the UI is moved in Update.
Where is the camera moved? Update? LateUpdate?

[proper needle]

.tag doesnt work

[verbal dome]

Move the UI in LateUpdate

Tbh the drifting is not too visible in the video you sent

I do see these weird black streaks though

[astral falcon]

I think, because you are trying to render on screenspace, the updat eof the canvas is falling behind the camera movement render

[proper needle]

why doesnt my col.tag work

[astral falcon]

First of all, why not use a 3d space canvas instead? And, you could try to force rebuild the layout with every update (not sure, thats a good idea performance wise, but you could test it)

[verbal dome]

Collision2D does not have a tag property

[astral falcon]

yep, world space. or try https://docs.unity3d.com/2019.1/Documentation/ScriptReference/UI.LayoutRebuilder.ForceRebuildLayoutImmediate.html

[verbal dome]

@proper needle You can get the collider from the collision and get the tag from that though

[proper needle]

is there a way to make triggers solid

[verbal dome]

A collider is solid if you uncheck "trigger" in the inspector

[proper needle]

ik but then i cant use ontriggerenter

[verbal dome]

You'd use OnCollisionEnter2D

Which you already are

[proper needle]

but then i cant call a tag

[verbal dome]

#💻┃code-beginner message

[cosmic dagger]

You can't have a solid trigger as a trigger is a volume of space that you can pass through. . .

[proper needle]

alr imma try

[astral falcon]

What issues, I guess meshes overlapping the button?

[proper needle]

this happens

[astral falcon]

at least on the canvas, yes.

[cosmic dagger]

The parameter is a Collision2D type, not a Collider type . . .

[astral falcon]

Is Unity.UI not a thing anymore in Unity 6?

[rich adder]

the name is col

collider is an old(obsolete) property of monobehaviours

[cosmic dagger]

Look at the type in the unity docs to see what properties it has (you have access to) . . .

[verbal dome]

I said "get the collider from the collision"
oncollisionenter gives you col which is of type Collision2D, and you can see what properties it has here
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Collision2D.html

[proper needle]

thanks that worked

[astral falcon]

The sorting layer is only "internally" for UIs. It will not let you draw the UI above your meshes. THerefore you would need an extra camera if you want it to be always on top

Thats why I suggested to try the forcerebuild layout

I am using Unity UI in 6, so its there, even if not in the docs weirdly enough

[proper needle]

now i have this error

[astral falcon]

Read it and try to assign the terms to your method

you know what a parameter is?

[proper needle]

alr thanks

[astral falcon]

Its in the docs I pasted. You give it the recttransform of your canvas as a param

did you try it in update?

I think, they dont do it with world canvas, as there is no perspective to the item. You just dont see the offset (if there is one), because there is not an object as close to it as on your example

[cosmic dagger]

Why did you change the parameter type?

[astral falcon]

What you also could try is to use screen space camera instead

Maybe that changes how things are rendered

[proper needle]

how do i make this so it actually works

[astral falcon]

It might just be unity being unity sometimes

[cosmic dagger]

OnTriggerEnter2D uses Collider2D, not Collision2D . . .

[astral falcon]

please learn to use the docs and read about "Unity collision2d", should get you going to the right place with an example code

[cosmic dagger]

Again, look at the Unity docs for Collision2D for how to access the tag. You need to attempt to solve the problem. Also, what is Collision2D? Is that your own custom method?

[proper needle]

someone here told me it was collision2d

i used oncollisionenter2d

[verbal dome]

No one said that though. You need to learn some C# basics, like what a parameter means. Check the beginner courses in the pins

[astral falcon]

guess you had it as world canvas and now the scale is messed up? 😄

[proper needle]

ik what a parameter is

i learned that from javascri[t

javascript

[cosmic dagger]

They were talking about the type, not the method name . . .

[astral falcon]

reset your transform of the canvas 😄

[proper needle]

when i do that tho i cant tag anything

[astral falcon]

Thats just the result of drag dropping back and forth between screen and world ui

[proper needle]

so now im stuck in this loop

[astral falcon]

please do the basic courses. you dont know what you are working with and that will bring you here for every line of code

[proper needle]

alr then

[astral falcon]

There are pathways on learn platform now, which will guide you

Right click on the component, reset

yeh, because its driven by the canvas now 😄 try to make it a world canvas again, then reset and then back to screenspace camera.

ah no wait, thats intended. because your camera is rotated. all should be fine. I guess your button is messed up

can you show the inspector of your X button?

[proper needle]

any recommendations

i need the c# documentation for oncollisionenter2d

[astral falcon]

and when setting camera, it gets huge out of a sudden? 😄 try to make the plane distance something small to see if that changes

[astral falcon]

then use your hands and eyes to type it in

[proper needle]

thanks

[proper needle]

i do that and it takes my years to find what i want lol

[astral falcon]

thats part of the learning curve

so, lets get back to your topic, which is not code related anymore, but whatever 😄

[proper needle]

bruh i look up unity documentation and go from there

[astral falcon]

Can you show your scene view with the camera attached?

read again 😄

There is Game View and Scene View

[verbal dome]

Tbh, Google is better for searching unity docs than the unity docs search itself

[astral falcon]

wait, two cameras?

Could it be, that you assigned the wrong camera while looking through the other one?

or was that screenshot with that huge UI from your scene view?

ah okay

and when assigned the main one, how does it look like?

Okay, that feels like some querks with cinemachine

when back to camera overlay, where do you set the positions? In lateupdate?

And what is your cinemachine brain set to update?

CInemachine Brain component

https://docs.unity3d.com/Packages/com.unity.cinemachine@2.2/manual/CinemachineBrainProperties.html

Yep, you could try to use another method so cinemachine is done with repositioning the camera before you calculate the UI. Otherwise, you take previous frame positions and that will result in that lag

at least worth a try 😉

[grand snow]

btw be warned there are differences between v2 and v3 of cine machine

but v3 has some nice newer stuff so do upgrade to it if not already

[astral falcon]

Is it part of unity 6 release or also usable in previous versions?

ah, just seen, its already in 2022

[grand snow]

it says 2022+ but projects I work on had v2 still but probably cus lots of common stuff comes from like unity 2019 and earlier

cinemachine is great it will make cool camera stuff super nice

[astral falcon]

Best of luck and success with your first project then 🙂 Im out for today, happy developing

There are plenty of people around 😄 Just ask and youll get answer sooner or later

[grand snow]

fun fact, cine machine was "ported" to unreal engine cus its soo good

[astral falcon]

happy to help 🙂

[zinc trellis]

Hey, any good courses i can follow for unity? Im a total beginner and would love to try game dev. Its been my dream

[verbal dome]

You using cinemachine would've been good info when I asked when you update the camera 😬

[astral pine]

@rich adder had to alter the code a bit but just wanted to say thank you. Everything works now 🙏

[ember tangle]

Im building a mesh via script and I am looking for learning resources on how to apply textures or materials to specific sections of the mesh

[earnest wind]

different from build to editor

in editor, all of the lines get executed

but in build, from like 66 it just stops

im building with IL2CPP

[wintry quarry]

Check the logs for errors

[earnest wind]

no errors

[wintry quarry]

Where did you look

[earnest wind]

let me try and make a development build

5 min-15min, i will come back

[wintry quarry]

Anyway what populates that list or array

It's probably just empty

[earnest wind]

which one

keyMeshifSkinned?

that one is empty

yeah but in unity editor it works, why would it not in build..

@wintry quarry

yeah but like if it were to be a object reference, why does unity editor allow it

its weird

i guess i just do that?

oh also, this script has been here for a long time

there were no issues with it, untill i switched to IL2CPP

[cosmic dagger]

[timber tide]

overlay shouldnt be moving regardless or am I misunderstanding

overlay canvas renders after main camera

unless you mean world space

you're saying UI elements are drifting this is this irrelative to the main camera

[grand snow]

ideally you have cine machine update in Update, the UI pos stuff is LateUpdate

or if you need both to be late update try to change the monobehaviour orders or as you said, use an event

[cosmic dagger]

what are you trying to do with the UI? what is the goal? i'm not understanding what is happening . . .

[grand snow]

maybe this will help?
https://docs.unity3d.com/Packages/com.unity.cinemachine@3.1/api/Unity.Cinemachine.CinemachineBrainEvents.html#Unity_Cinemachine_CinemachineBrainEvents_BrainUpdatedEvent

[timber tide]

is this like a 3D object being converted to screen space when you pick it up?

[grand snow]

the problem is the world -> screen pos must be before the camera changes in this frame

well you want the camera transform to have changed already, THEN do the world -> screen pos conversion

otherwise its going to be "out dated"

so you want:
player moves -> cinemachine updates stuff -> worldscreen pos for UI element

[timber tide]

yeah that's probably it. Cinemachine has a few options for when it should be ran too somewhere on it which you can screw around with
