[buoyant knot]

and know that when you execute Physics2D.Simulate, the game will:

1. Solve physics,
2. move stuff
3. Execute collision/trigger callbacks

all of this happens in that line. you cannot wedge any code in between, and know that any code you write in the lines after Simulate() is AFTER all OnCollision… basically like LateFixedUpdate (if it were a thing)

[silver flicker]

got it

ill look into that a little bit more in that case

[buoyant knot]

just giving you info because the documentation does not have the details

it might as well say “run the physics simulation lol”

[silver flicker]

Yeah I can see that on the website lol

i appreciate it

[ashen wind]

is there a way to check collision without using ontriggerenter2d and ontriggerexit2d?

like check immediate collision?

I'm trying to do a thing where I place a building only if it's not intersecting with another 2d collider

and have it be greyed out if it is intersecting

but for that I need a bool that's only true when no colliders are intersecting

and the enter and exit functions are not behaving as expected

nvm, figured it out. It's OverlapCollider()

[craggy oxide]

Can someone explain this snippet to me? (Taken from the Unity documentation site)
I get that it creates a raycast 10 units forward from the GameObject

But how is it an If statement
And how does it detect that there's something in front of the object

this is the full thing

[polar acorn]

If the raycast hits something, it returns true. If the raycast does not hit anything, it returns false

[craggy oxide]

So the if statement actually creates the raycast and listens for it returning true simulataneously?

[polar acorn]

I don't know what you mean by "creates the raycast"

[swift crag]

I wouldn't say anything is "simultaneous" here

[craggy oxide]

casts the ray

[rare basin]

it's a bool type method

[swift crag]

if (whatever) evaluates whatever

[polar acorn]

It is just checking if anything in that line

it's math

no objects are created or listened for

[swift crag]

in this case, it evaluates Physics.Raycast(transform.position, fwd, 10)

If that expression evaluates to true, then it executes the following statement

[polar acorn]

it checks if the line with those properties intersects a collider, and returns true if it does

[craggy oxide]

and if its evaluated as false it returns nothing?

[swift crag]

It never "returns" anything.

[polar acorn]

it returns false

[craggy oxide]

does it execute the next statement or not

[swift crag]

In this case, since there's no else or else if, it just skips its statement and execution continues.

[polar acorn]

Does if (false) something; execute something

[craggy oxide]

probably not

[polar acorn]

Do you know what if does

[craggy oxide]

yeah i've just never used it in such an odd context

well, odd to me

i'm a beginner

usually my ifs actually listen for say... a trigger or two values syncing up or something

[polar acorn]

How is it odd? You put in a condition, and if that thing is true, it runs the code inside the if

[craggy oxide]

ive never encountered an if statement that listens out for something like that

[swift crag]

you are over-thinking how if works

It doesn't "listen"

[summer stump]

if (MethodThatReturnsABool())
Think of it like that

[polar acorn]

What do you mean "listens out"

[swift crag]

It evaluates an expression.

[craggy oxide]

bro im just wording it badly you know what i mean

[polar acorn]

it literally just checks a true or false

[swift crag]

If the expression is true, it executes its statement.

[craggy oxide]

fine, evaluates an expression, whatever

[polar acorn]

like always

[swift crag]

That's all it does, ever.

[polar acorn]

if (x == 3) also evaluates an expression

[craggy oxide]

alright alright i get it

[swift crag]

if (true)
if (1 == 1)
if (3 < 5)
if (MethodThatReturnsTrue())
if (6 != 4)

[craggy oxide]

I GET IT

[polar acorn]

if (someBoolean) also evaluates an expression

[swift crag]

all of these will have the same outcome

[craggy oxide]

All I need to know is, does the if statement evaluate the raycast returning true/false, and then executes the following statement if it returns true

Yeah?

[swift crag]

As always.

[polar acorn]

An if statement checks if the thing inside the () is true. If it does, it runs the code in the if

[craggy oxide]

Alright, thank you

[swift crag]

There is nothing special here, and there's never something special here.

We are confused about why you're asking the question at all.

It suggests you misunderstand something.

[summer stump]

Raycast is a method. It just returns true or false
The if statement doesn't evaluate the raycast itself, the raycast just returns

[buoyant knot]

raycast is overloaded

[craggy oxide]

actually this poses a new question

if the If Statement is evaluating the raycast, what actually casts the ray in the first place for it to be evaluated

[polar acorn]

But every overload returns bool

[buoyant knot]

can return a bool or a raycasthit2D

[polar acorn]

Physics.Raycast

[buoyant knot]

oh, idk about 3D

[polar acorn]

Raycast cannot return a raycastHit2D. Raycast2D cannot return a bool

you can't overload a return type

[craggy oxide]

alright....

[summer stump]

The code of the Method.
Again, the if statement is NOT evaluating the raycast

[craggy oxide]

i think i get it

[craggy oxide]

bro you're getting caught up in semantics here

[buoyant knot]

2D raycast can return an int or RaycastHit2D

[craggy oxide]

i'm just bad at phrasing this

[swift crag]

you're asking a question about semantics

[polar acorn]

That function returns true if the line you define intersects a collider.
It returns false if the line you define does not intersect a collider.

That's it

[buoyant knot]

https://docs.unity3d.com/ScriptReference/Physics2D.Raycast.html

[craggy oxide]

okay anyway i got all i needed so thank you

[summer stump]

bool MyMethod() {
  return false;
}

if (MyMethod())

This is important, not getting caught up in it

[buoyant knot]

why did they do it this way? idfk, but they did

[polar acorn]

2D Unity used to be an entirely separate program way back in the day

They did things slightly different

My guess? The 2D people didn't know out parameters existed

[buoyant knot]

2D physics methods are strange. they populate arrays/lists that you feed in so they can do everything non-alloc. But they don’t pass them in as ref

[polar acorn]

There's NonAlloc methods for 3D as well

[swift crag]

you don't need to pass them as ref

[fiery fjord]

I am making a multiplayer game using Relay. Everything is working correctly and connecting fine, but I am having an issue with NetworkVariables.

For some reason, after my client joins the server, it does not retrieve the values such as the "LobbyCode" NetworkVariable nor does it retrieve the "LobbyNames" NetworkList.

The first image is where the problem occurs and both NetworkVariables are default when retrieved while the second image (Creating a lobby), the variables are set correctly. It's almost as if the client is setting the variables as default while the client should not have any write perms.

Any help would be greatly appreciated! (P.S. unsure if there is a channel specifically for multiplayer questions, I'm sorry if I am in the wrong spot)

[swift crag]

that wouldn't really accomplish anything unless you wanted to completely overwrite the variable the user provides

[buoyant knot]

isn’t ref the main way to indicate that a function is going to go modifying your input args?

at least in the context of lists and arrays

[polar acorn]

if that type was a value type. Arrays are reference types

[swift crag]

It shares the actual variable.

[buoyant knot]

right now, you’re just kind of expected to know that the input array is actually getting modified

[swift crag]

public void MessWithList(ref List<int> theList) {
  theList = new();
}

this assigns a new list into whatever variable was passed as an argument

vitally, this is nothing like just modifying the contents of the list you were given

public void MessWithList(List<int> theList) {
  theList.Add(123);
}

[buoyant knot]

correct, but how else do you indicate that your method is going to actively modify the contents of the collection?

[swift crag]

by documenting it

ref should not be used for documentation purposes

the parameter name should make it obvious, and the method's documentation should also describe what it's going to do

[polar acorn]

//

[swift crag]

ref does not mean "I might modify your reference type"

[buoyant knot]

the non alloc methods are effectively taking in your variable and messing with it, as though they have a ref to it anyway

[swift crag]

no, they do not

they mess with the thing you have a reference to

they don't touch your variable at all

[buoyant knot]

true. I just find it strange to make methods that try to modify the input

[swift crag]

every instance method is a method that modifies its input (:

[buoyant knot]

input arguments

[swift crag]

what is this but an implicit zeroth argument?

[buoyant knot]

i expect an instance’s methods to be able to modify the instance

that is sus

[polar acorn]

Not true, it's entirely possible to have a stateless method, one that could 100% be made static but for whatever reason is not

[swift crag]

oh yeah, I should say every one could

C# gets mad if you call a static method from an instance..

C# has no equivalent to c++'s const qualifier on methods

which promise that the method has no effect on the instance

[deep quarry]

This is my script for accelerating my rocket:

    void MyInput()
    {
        if(Input.GetKey(KeyCode.LeftShift))
        {
            accelerating = true;
        }
        else {
            accelerating = false;
        }

        if (accelerating)
        {
            if (moveSpeed !< maxSpeed) 
            {
                Debug.Log("Accelerating!!");
                moveSpeed *= 1.001f;
            }
        }
        else {
            moveSpeed = moveSpeed / 1.02f;
        }
    }

Later, I add a force by:

        if(accelerating) 
        {
            rb.AddForce(Vector3.up * moveSpeed * Time.deltaTime, ForceMode.Force);
        }

However, when I press LeftShift the moveSpeed variable doesn't increase. When I remove the

        else {
            moveSpeed = moveSpeed / 1.02f;
        }

part it works. Any idea why?

[swift crag]

!< does not do what you think it does

you've actually written moveSpeed! < maxSpeed

although I guess that's technically fine here

[cosmic dagger]

!< 🤔 is different than you think . . .

[swift crag]

you probably just wanted moveSpeed < maxSpeed

[short hazel]

Structs got that, you can put a readonly modifier on a method! Not sure which version this was introduced in though

[swift crag]

I have it on a get accessor, actually..

Ah, there it is!

[cosmic dagger]

If you want "not less than," that is called "greater than" . . .

[swift crag]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/readonly#readonly-instance-members

[deep quarry]

Oh gosh im stupid haha
Thank you!

[swift crag]

That shouldn't change anything, though

! is the null-forgiving operator, which isn't going to do anything here

[deep quarry]

Well it works now :3

[swift crag]

Perhaps you had that else { moveSpeed = moveSpeed / 1.02f } in the wrong place before.

[twin bison]

Hi guys. Beginner question: Why is this code not showing up in the inspector of the object:

public float BulletSpeed { get; set; }

if i leave { get; set; } away it will show up

[SerializeField]
public float BulletSpeed { get; set; }

Wont work either unfort

[languid spire]

because properties are not, by default, serializable

[swift crag]

public float BulletSpeed; declares a field.

[languid spire]

use the correct attribute
[field:SerializeField]

[twin bison]

Ok that works. Whats the difference between these two:
A:

[field: SerializeField]
    public float BulletSpeed { get; set; }

B:

[SerializeField]
    private float BulletSpeed;

[swift crag]

public float BulletSpeed { get; set; } declares a property with auto-implemented properties

https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/fields
https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/properties

properties "look and feel" like fields, but a method is called when you read or write them

[twin bison]

thank you very much for the links very helpful 🙂

[languid spire]

man, you need to learn some basic c#

[swift crag]

auto-implemented properties create a backing field that stores the value

[twin bison]

comming from javascript you are most likely right 😄

[swift crag]

hence needing to specifically target the backing field with [field: ...]

otherwise your attribute targets the property

[twin bison]

but now that it works and its my kinda first steps with OOP im kinda proud of this:

abstract class Weapon : MonoBehaviour
{

    void Start()
    {
        Debug.Log("Start");
        Shoot();
    }

    [SerializeField]
    public float Damage;
    [field: SerializeField]
    private float BulletSpeed { get; set; }
    public GameObject BulletPrefab { get; }
    public float Cooldown { get; set; }
    public abstract void SetupShot();

    public virtual IEnumerator Shoot()
    {
        while (true)
        {
            SetupShot();
            yield return new WaitForSeconds(Cooldown);
        }

    }
}

feels so good man 😄

[languid spire]

that aint gonna work

[twin bison]

You are right:

class SimpleGun : Weapon
{
    public override void SetupShot()
    {
        Debug.Log("Shoot simple gun");
    }
}

This wont get logged at all

[languid spire]

Shoot is a Coroutine, you cannot call a coroutine with Shoot()

[late burrow]

how to do reverse of %

[twin bison]

ah yeah yeah yeah

that one i knew but was an oversight 😄

[buoyant knot]

o\o

[late burrow]

to count how many of certain number fit in certain number

[buoyant knot]

you mean Min()

[polar acorn]

division?

[swift crag]

that's just division

[late burrow]

full digit division

[swift crag]

x / y + x % y == x

i hope operator precedence goes the way I think it does

[polar acorn]

division, then floor

[buoyant knot]

still not sure what he wants

[late burrow]

fine, thought of cheaper function

[twin bison]

abstract class Weapon : MonoBehaviour
{

    void Start()
    {
        Debug.Log("Start");
        StartCoroutine(Shoot());
    }

    [SerializeField]
    public float Damage;
    [field: SerializeField]
    private float BulletSpeed { get; set; }
    public GameObject BulletPrefab { get; }
    public float Cooldown { get; set; } = 1f;
    public abstract void SetupShot();

    private IEnumerator Shoot()
    {
        while (true)
        {
            SetupShot();
            yield return new WaitForSeconds(Cooldown);
        }

    }
}

This now works.
Now it #feelsgoodman 😄

[buoyant knot]

#Inspirational

🏅🌏🔑

[languid spire]

this

[field: SerializeField]
    private float BulletSpeed { get; set; }
    public float Cooldown { get; set; } = 1f;

is completely pointless

[SerializeField]
    private float BulletSpeed;
    public float Cooldown = 1f;

does the job correctly

[swift crag]

the only reason to use a property there is if you want children to be able to override it

but then...

• it'd need to be virtual
• there'd be no point in serializing it

I suppose that children that don't override it could just leave it untouched, which would give you a serialized value for it

[twin bison]

Yep i get it now. I had it kinda like this because i wanted to understand why with getter and setter it wont show up in inspector. But now that I get.

[swift crag]

don't cross-post and don't spam

#1180170818983051344 is appropriate.

[craggy oxide]

i want you guys to double-check this to make sure im understanding correctly

if (Physics.Raycast(myRay, out RaycastHit hit, maxDistance, layersToHit))

// myRay - Specifies the raycast that should be involved in the If Statement.
// out - Output: Creates a new method parameter, specifying that it returns an additional value on top of the method's default return values.
// RaycastHit hit - Creates a RaycastHit variable called "hit" (In order to store the collision data)
// maxDistance - Specifies how far away from the Raycast origin that the If Statement should apply for.
// layersToHit - Specifies which layers the raycast should interact with.

[swift crag]

None of this has anything to do with the if statement

Physics.Raycast(myRay, out RaycastHit hit, maxDistance, layersToHit)

This calls Physics.Raycast with the provided arguments.

[craggy oxide]

but are my definitions of the "provided arguments" correct?

am i understanding it all correctly

remember that terms such as "out" and "RaycastHit" are new to me

i need to know that my understanding of the arguments is sound

if it isnt correct me

[swift crag]

ignoring the thing about if, yes, it's reasonable

[craggy oxide]

in its entirety?

im right about all parts?

[swift crag]

out is a keyword that passes an argument by reference so that the method can assign something into it.

and since you're using out, you're allowed to declare a new variable right as you use it

[polar acorn]

myRay is not a Raycast, It's a ray
out is a C# term that specifies a new variable that will be created by the function and given as output
The rest is fine

[swift crag]

rather than using a variable you declared earlier

RaycastHit hit;
Physics.Raycast(myRay, out hit, maxDistance, layersToHit);

Physics.Raycast(myRay, out RaycastHit hit, maxDistance, layersToHit);

Same outcome.

[craggy oxide]

Thank you.

[languid spire]

wait just a second. GC?

[swift crag]

I see no reason for that to come up here.

[polar acorn]

Both get GC'd, just at different times, belonging to different scopes

[swift crag]

RaycastHit is a struct anyway

[languid spire]

yes, which can make one hell of a difference

[swift crag]

also, they live in the same scope

[polar acorn]

I think the one declared inside the function exists inside the if scope (if there is one)

[swift crag]

if (Whatever(out var foo))
{

}

print(foo); // foo is still here

[polar acorn]

Ah, then they're the same

[languid spire]

no it is not

[swift crag]

yes it is. you can try it yourself

if (!target.TryGetModule<Visible>(out var visible))
  continue;

float angle = Vector3.Angle(forward, visible.entity.transform.position - from);

random example

[summer stump]

That is how I do it all over my codebase

It is lost after the NEXT scope end, but it exists outside the if statement for sure, as you said

[swift crag]

lexical scoping rules apply as per usual

a somewhat ambiguous-looking case gets resolved by a compiler error

if (true)
    int x = 3; // error CS1023

the compiler just forbids declarations here

[polar acorn]

I didn't actually know that. I'd never thought it might exist outside the scope so any time I needed to I just defined the variable outside the if

Neat

[swift crag]

It'd be a chicken and egg problem

the variable must exist to evaluate the if expression, but it can't exist until you enter the block statement

[summer stump]

Not really a code problem. Try #💻┃unity-talk

[kindred marsh]

kk

[eternal needle]

Pretty sure the 2nd one would be compiled to the first one anyways

[swift crag]

sugar in the eyes of an angry compiler

[twin bison]

How can I make this

[SerializeField]
    protected Transform ShoootingPos;

To be by default the transform of the gameobject the script is attached to? Kinda like make it optional?

[swift crag]

wait, it was sinners in the hands of an angry god

close enough

[swift crag]

the most practical thing is to just assign something in Awake

if ShootingPos is null, assign your own transform to it

[twin bison]

so basically check if its null? and then assign?

[swift crag]

yes

[twin bison]

ok thx 🙂

[earnest atlas]

private void OnTriggerEnter2D(Collider2D other)
{
    if (other.gameObject.layer!= _playerMask) return;
    GameController.Instance.Score++;
    if (_audioClip != null)
    {
        // Play the audio clip at the specified position
        AudioSource.PlayClipAtPoint(_audioClip, transform.position);
    }

    Destroy(gameObject);
}```

When I change this from Compare tag to layer it stops working?

I mean its working but its not detecting player

[slender nymph]

1. why do you need to check the layer in the first place?
2. the layer property is not a mask

[summer stump]

You seem to be comparing a layer to a layermask

[earnest atlas]

Omg

How to compare layermask?

or what I needed to do

[slender nymph]

why do you need to check the layer in the first place? why not go back to using a tag?

[earnest atlas]

Someone said to check for layers

[summer stump]

You can check that the layermask contains that layer. But yeah, I dunno if this is the best way

[earnest atlas]

okey will go back to tag

[summer stump]

I listed layers as a method of collision validation, but it was the last of three suggestions. And I more meant using the collision matrix to reduce collisions you have to check

[earnest atlas]

I dont understand how collision matrix setting works

[summer stump]

Ignore it

Just do tags

[earnest atlas]

Yeah I just reverted to tags

[summer stump]

If you need more complex functionality, also check if a component is on the object using TryGetComponent

[earnest atlas]

I have this at some places

[slender nymph]

for future reference though, this is how layermasks work and what they are https://unity.huh.how/bitmasks
again though, it is not necessary here.

[earnest atlas]

But mostly its not needed due to most of my scripts positioned on the object of interest

Yeah I know how access layermasks

I got told something about this

[earnest atlas]

This

Seen the setting

And understood nothing

And recently I done few changes to remove lots of GameObject.Find and still dealing with aftermath

[summer stump]

You just put a checkmark where you want collisions to occur. If there is not a check where two layers line up, they will not collide

[earnest atlas]

collide like fisical collide or trigger?

[slender nymph]

both

actual collisions and collision/trigger messages do not happen

[earnest atlas]

Oh then im going to edit that and see what happens

its just build takes at this point a minute

[lost sluice]

does anyone know why this is happening? i'm following the sebastian graves tutorial for dark souls and my camera just shoots away from following the player. when i move the player the camera still moves. but why is it like this?

[slender nymph]

you'd have to show relevant !code

[vague dirge]

Hello, how can I get the normal direction of a face ?

[ivory bobcat]

Define face. A plane would have the normal property.

[vague dirge]

Like have a checkbox for what my character is on, but I'd like to get also the normal direction info

[rare basin]

define normal direction info

[vague dirge]

Yes exaclty like the normal of a face from a mesh

[ivory bobcat]

If the "face" is a plane, it should have the normal property else using some math logic, you'd be able to get the normal of the plane given two vectors https://docs.unity3d.com/ScriptReference/Vector3.Cross.html

[lost sluice]

so do i post ot on one of these sites? then what?

[craggy oxide]

How do I change the color of the collided GameObject back to it's default if it's not being raycasted onto?

[rare basin]

else

[craggy oxide]

yeah but I mean what's gonna be in the else statement

[ivory bobcat]

The site should have a save button somewhere on the screen. The URL will change after saving and you'd post the url here.

[craggy oxide]

just else return or some shi?

[rare basin]

assignement to the default color

[swift crag]

this is a pretty common question

you need to remember the last thing you hit

[vague dirge]

And quickly how can I get the plane I'm standing on ?

[swift crag]

then, if your raycast either:

• hits something else
• misses entirely
  you can reset the color of the last thing you hit

[ivory bobcat]

How do you know there's a face under you?

[swift crag]

You can store the last Renderer that you changed the color of and then compare that against the Renderer that you just found

[craggy oxide]

how do i do that

[swift crag]

store the Renderer in a field so that you can access it later

[lost sluice]

https://gdl.space/yewuxefape.cs

[craggy oxide]

what about the comparison part

[swift crag]

just compare them with the == operator

or maybe !=, since we want to do something when they differ

[vague dirge]

Rather how I get its information. I have a checkbox, and the is there a method the get the touched pkane information ?

[swift crag]

if (oldRenderer != newRenderer) {
  if (oldRenderer != null)
    oldRenderer.color = ...
  if (newRenderer != null)
    newRenderer.color = ...
}

oldRenderer = newRenderer;

that's the broad idea

that doesn't look like a real word anymore

[earnest atlas]

why null check after checking it to new renderer?

[craggy oxide]

is there a way to automatically find the color so i don't have to manually input it in, for example if there was different colored objects

[swift crag]

because the new renderer could be null

[swift crag]

store the color as well as the renderer

[earnest atlas]

first check if they are null then contine?

[swift crag]

e.g. if your raycast hits something with no renderer

[craggy oxide]

Even if the new renderer is null, we still might need to reset the old renderer's color

if the old renderer isn't also null

old renderer <-- not null
new renderer <-- null

this means we just went from pointing at a renderer to not pointing at a renderer

you'd get newRenderer a bit like this

Renderer newRenderer = null;

if (Physics.Raycast(...)) {
  newRenderer = hit.collider.GetComponent<Renderer>();
}

if the raycast whiffs, it's definitely null

[ivory bobcat]

Consider using one of the physics casts

• 2D: https://docs.unity3d.com/ScriptReference/Physics2D.html
• 3D: https://docs.unity3d.com/ScriptReference/Physics.html
  Under the static methods section

[swift crag]

if the raycast hits, then it might become non-null, assuming the thing we hit has a renderer

[vague dirge]

Gonna check this out, thank you !

[vernal minnow]

How can I set up a scoreboard for my enemies? They seem to be destroyed because I can do anything with them

The only fix I have in my head is having them pull the game controllers script on start so that on collision with a bullet, they add to the controllers score

[swift crag]

what will this scoreboard do?

is it tracking each enemy's score?

or is it tracking how many points the player has?

[earnest atlas]

that is a fine way

[vernal minnow]

Just shows players score

[earnest atlas]

issue comes if you have multiple levels

[swift crag]

okay, so the enemy needs to notify someone when they get destroyed

[ivory bobcat]

Every object (via Transform component) would have a forward and up. That would be two vector and define the orientation of the object. Forward would be the normal for a 3d surface btw. If you're wanting the normal for a 2d object, it'll require a bit more math.

[earnest atlas]

You need DDOL object to store score to pass it between levels

[vernal minnow]

The controller isn't destroyed on load to save my stats

[swift crag]

The only fix I have in my head is having them pull the game controllers script on start

Whoever instantaites the enemy should pass them a reference to the controller, yeah

[earnest atlas]

just save score in controller and make it singelton and access it to get score if u need it elsewhere

[honest haven]

[vague dirge]

I looked at the links you set, my strategy will be to get a raycast hit normal, at least that what seems the esasiest for me

[vernal minnow]

I have no idea how to access the score if there is a more normal way

[vernal minnow]

So grab the scoreboard with the player on start and pass it onto the instantiated bullets?

Only if shooting enemies is, itself, worth points, IMO

but I guess it would be a good way to indicate who shot the enemy. That'd matter if enemies could shoot each other without giving you points

[earnest atlas]

https://hatebin.com/kvheyytnba

This is my GameController class.

private void OnTriggerEnter2D(Collider2D other)
{
    if (!other.CompareTag("Player")) return;
    GameController.Instance.Score++;
    if (_audioClip != null)
    {
        // Play the audio clip at the specified position
        AudioSource.PlayClipAtPoint(_audioClip, transform.position);
    }

    Destroy(gameObject);
}```

This is my gem class that I use to get score

[vernal minnow]

When the enemies due, they should give points, and mostly are 1 shot (minus the boss)

[earnest atlas]

As you see I access score by accesing Instance that is static

[vernal minnow]

Wait is an instance what the clones are?

[earnest atlas]

instance is the unique instance of that class

Almost finished I am but Domain starts to take a minute to get anything done

[summer stump]

Instance is a reference to itself. It is static so it can be accessed from anywhere.

[earnest atlas]

Otherwise you will make new instance of the class each time you want to acess a value and will need to make all those values static too

[summer stump]

Well, reference. You could keep the same instance.

Unless I'm missing some context?

[earnest atlas]

Well if I know C# well enough only way you can pass same instance of class without static is by directly passing it

You will basically have a tree of references

[vernal minnow]

Wait so which instance is this pulling, a bullet or an enemy?

[earnest atlas]

Its a controller object

[summer stump]

Basically true... some nuance is missing

[earnest atlas]

I have it dealing with Scene changes, storage, spawn on points etc

[vernal minnow]

Ah, so yours controls the spawners... hmn

I may have to restructure my code

[earnest atlas]

I have it control the spawn because of what I spawn

Also probably will spawn the portal from start because it causes a lag spike

[lost sluice]

https://hatebin.com/ejuytvpqdh

[scarlet skiff]

i solved the problem, i saw how my structure was flawed and i solved it, this is how it is now for nayone wondering

[earnest atlas]

that "this" is irrelevant

this exists to differentiate variables from class and method that have same name

[summer stump]

The only code that actually runs here is Awake. Is there another script that calls the other methods?

[lost sluice]

https://hatebin.com/jjlmgairnl

there's this. the InputHandler script that i got from the same tutorial

[earnest atlas]

Instead of public transform reccomend using [SerializeField] private

Also most of these can be achivmed with transform or gameobject references

[earnest atlas]

you have nothing running on FixedUpdate or Update so this code runs once and only Awake part

[vernal minnow]

So ig I also have question 2, to pass the level, I had this (possibly ridiculous idea) of setting spawner references to the game object that added a counter for my enemies, basically they all spawn until +20 are created before quitting, and they then deactivate themselves, as all the spawners and enemies would have a trigger with the background so that the game knows when they are all dead since the game won't unlock level 2 until
First- all enemies are spawned and the spawners are done
And secondly, all the enemies are dead allowing the level 2 gate to open

[lost sluice]

how do i fix it?

[vernal minnow]

Yeesh that's more than I thought

[earnest atlas]

add void Update() (This runs every frame)
Or void FixedUpdate (runs every set time, dont know well but movements should go here)

Also you can use cinemamachine to make camera go after someone

[lost sluice]

which line do i add void Update()

[earnest atlas]

this is a unity method

that runs every frame

[summer stump]

They have FixedUpdate already

[earnest atlas]

where?

I dont see any

https://hatebin.com/ejuytvpqdh

you looking at this?

[vernal minnow]

Eh, reworded would be I'm confused on how to make an enemy detection system bc I was told that finding an object with a certain tag was laggy

[summer stump]

Line 22

[earnest atlas]

you can serialize field and set that object

[summer stump]

No, that script is controlled by the other
The second script has the fixed update

[earnest atlas]

laggy is constantly searching for it

[earnest atlas]

ah then no need

if you search for it once in a scene its not end of the world

[summer stump]

Is MoveInput supposed to be a callback? That isn't called anywhere I see

[vernal minnow]

It needs to find it until all are dead

I just don't know how to prevent it from breaking when it no longer finds an object

[earnest atlas]

why just not make an empty object that holds all enemies and serialize this then just count how many children it has?

[vernal minnow]

The enemies are instantiated

[earnest atlas]

add them to that object as children

Basically most of commands that are not GameObject.Find() are not really coputation heavy at least at beguinner levels

[lost sluice]

i'm not sure. i was just following the tutorial

[vernal minnow]

So running a fixed update find for a tag wouldn't be to strenuous?

[modest dust]

What exactly are you trying to achieve? And for what reason does it need to find them if you instantiate them and therefore already have a reference to them?

[earnest atlas]

also that

tho reference not gonna be of much use

unity wont automatically set object as null

[modest dust]

Didn't read everything so I don't know the exact context

[earnest atlas]

you can tho save amount of created enemies into variable in DDOL class with public variable and minus the dead ones

[vernal minnow]

I need a way to know how many enemies were spawned, or at minimum, to make sure that all enemies are killed before the game is allowed to move on to level 2

[earnest atlas]

when you inicialize enemy add 1 to a variable in gamecontroller class

when it dies just minus 1 from there

and when it reaches 0 you can just load next level

[modest dust]

Why not then just have a counter which increases with each enemy spawned, and decreases with each enemy killed?

[vernal minnow]

I understand that, I'm not sure how to remove them

[earnest atlas]

just do same as adding them

instead of ++ do --

If health is not going to start working soon my brains gonna melt

[vernal minnow]

It's not the same though, the spawners aren't going to keep track if their spawned unit was killed

[earnest atlas]

they dont need to

how do you kill an enemy?

just access the variable from there

it doesnt matter from where what matters is the count

[vernal minnow]

The bullet collides but in doing so, destroys itself before sending back the object it hit

[summer stump]

If you're not sure, you need to go back and follow the tutorial again until you know.
Sebastian Lague tutorials are a bit higher level, and considering you asked which line Update should go on, I think you may need to go and do some more basic tutorials first.

[earnest atlas]

before it commits sepucu just add a line that acces variable like this
GameController.Instance.EnemyCount--;

literally it matters not

[modest dust]

Either access the variable from within the enemy, or make an OnEnemyDeath event for the counter to subscribe to, or pass a delegate to invoke upon death

[vernal minnow]

So give the bullet a reference to the count on start, and allow it to -- it before it goes poof?

[earnest atlas]

You dont need reference

Just call it when its killings something

this is pros of singleton class

[vernal minnow]

Then how would it know that a count even exists?

[earnest atlas]

It does not needs to

Literally just
if(hitenemy)
SingletonClass.Instance.Count--;
CommitDieOther
CommitDieMe

when you create an enemy just do this
Instantate(enemy)
SingletonClass.Instance.Count++

[vernal minnow]

Hold up, are all of my variables singletons?

I feel like I use public static alot

Just looked up singletons bc I've never heard the term before

[modest dust]

Here's a delegate solution of how you could do it.

public class Spawner : MonoBehaviour {
  [SerializeField] Enemy m_enemyPrefab;  
  private int m_counter;

  public void Spawn() {
    ++m_counter;
    Instantiate(m_enemyPrefab).Init(OnEnemyDeath);
  }
  
  public void OnEnemyDeath() {
    if (--m_counter == 0) {
      // Unlock level
    }
  }
}

public class Enemy : MonoBehaviour {
  private Action m_onDeath;

  public void Init(Action onDeath) {
    m_onDeath = onDeath;
  }

  public void Kill()
  {
    m_onDeath?.Invoke();
    Destroy(gameObject);
  }
}

Using events is also a good solution I suppose

[vernal minnow]

Objects have an on death action?

Box save this guy pls

My unity crashed just great

[ashen wind]

you know in games where you place a building and the unplaced building hovers over your cursor until you click

I'm doing that, and the following code is supposed to make the unplaced cursor building snap to the grid cell that it's over

        Vector2 cursorPos = Camera.main.ScreenToWorldPoint(Input.mousePosition);        
        Vector3Int cell_coords = gs.tilemap.WorldToCell(cursorPos);       
        transform.position = gs.tilemap.CellToWorld(cell_coords);

the problem is, there's some kind of offset

the final transform position that gets set is wrong and ends up misaligned with the grid

I'm worried it's related to the fact that grid cells have their transform.position point in the top left

and the building has it in the center

[vernal minnow]

@earnest atlas @modest dust thanks for your help fellas

[clear seal]

is that logic?

if the player trigger the canon

it will start the update

then the update will wait until the shoot is ended and it will repeat?

right?

[polar acorn]

Update runs every frame, which means the IsCoolDown coroutine starts once per frame.

In OnTriggerEnter, if this collides with something tagged player, it'll start a coroutine. This coroutine will check if the F key was pressed this frame. If it does, it does a bunch of stuff including a wait of 1.25f. If the key was not pressed this frame, the coroutine waits 4 seconds, does nothing, then ends

[ashen wind]

why are you calling starcorroutine in update

won't that create a new coroutine every single frame?

[polar acorn]

It does

[ashen wind]

why would you want that

[polar acorn]

They probably don't and simply do not understand how coroutines work

[ashen wind]

oh gotcha

@clear seal update doesn't need to be triggered

it'll call constantly as often as it can

[clear seal]

but then how do i make it work?

[ashen wind]

so you just want it to shoot if it's off cooldown and not shoot if it's on cooldown?

[clear seal]

yep

[ashen wind]

you can use coroutines for that, but I find it's typically simpler to just use a timer

lemme give an example

public float cooldownTime = 1f;
private float cooldownTimer = 0f;


 
  void Update()
    {
        if (cooldownTimer > 0)
        {
            cooldownTimer -= Time.deltaTime;
            if (cooldownTimer < 0)
                cooldownTimer = 0;
        }

        if (Input.GetKeyDown(KeyCode.F) && cooldownTimer <= 0)
        {
            Shoot();
            cooldownTimer = cooldownTime;
        }
    }

    void Shoot()
    {
       // shoot code goes here
    }

[polar acorn]

If you want to use coroutines it's a simple matter of setting a bool to false, then starting a coroutine that has a wait, then sets that bool to true

[timid saffron]

are the codes written in junior programmer unity courses well optimized codes or are they like the codes from beginner youtube tutorials that are poorly written for people to understand easier

[polar acorn]

if it's true, you can shoot

[ashen wind]

actually that probably is a bit simpler

since waitforseconds does this same thing in one line

[polar acorn]

Remember that Coroutines are Co routines. They run alongside the rest of the code. Nothing will wait for a coroutine to finish, so having the last line of a coroutine be a wait is 1000% pointless

[ashen wind]

   
 void Update()
    {
        if (Input.GetKeyDown(KeyCode.F) && canShoot)
        {
            StartCoroutine(ShootWithCooldown());
        }
    }

IEnumerator ShootWithCooldown()
    {
        canShoot = false;
        Shoot();
        yield return new WaitForSeconds(cooldownTime);
        canShoot = true;
    }

[summer stump]

Phone coding is too slow again. Almost had it done haha
Do it like that goldwerdz☝️

[ashen wind]

anyone know a workaround for this?

I'm pretty sure it's the pivot, but it could be something with the CellToWorld function rounding or some nonsense like that

the only thing that makes me think it's not the pivot is that I tried with a gameobject that has a transform instead of a recttransform and it's still off

[potent echo]

Hey guys, I wrote a script EnemyController (https://gdl.space/inijebuyap.cs) and within it there exists the ShootBullet method. This method instantiates a bullet (BulletScript: https://gdl.space/fikoluxawa.cs) and sets it's moveDirection based off which direction the Enemy is facing. This works fine when there's only one instance of an Enemy, but when there are more (and are both facing the player from different sides), they both start shooting in the wrong direction.

[fierce shuttle]

Do you have an example of code from that course you are concerned about? Also can you elaborate on what you mean by "optimized"? Usually there are many ways to solve a problem, and later on architecture can play a role in helping with that too, though optimizing usually suggests a concern with performance such as low framerate, memory management, rendering draw calls, etc, unless your referring to something else?

[teal viper]

Are we talking about 2d or 3d here?

[ashen wind]

this is 2d

[teal viper]

And the camera is set to orthographic and has 0 rotation?

[ashen wind]

correct

[teal viper]

Try drawing a ray at the world position of the cursor.

Or some other gizmo

[timid saffron]

I heard in a youtube video that he says you shouldnt watch these beginner tutorials on youtube because they make you learn coding part poorly so in the future when you make a game you can face lots of problems

so i try to learn it right from the start

so is unity junior programmer a good place for this?

[teal viper]

Thing is, you're not supposed to stay on the level you learn as a beginner.

Your knowledge/understanding and coding skills in general are supposed to improve over time.

It's fine to write unoptimized code and use bad practices at first, but you'll learn better coding with time and experience.

[summer stump]

Learning from mistakes is importance. Learning what others tell you is right from the beginning actually hinders you imo

The flip side is that you need to strive to learn and not let bad habits become ingrained

[teal viper]

The problem with the tutorials is that they give you partial understanding for the sake of achieving a specific mechanic or even plain out hand you the implementation on the plate without you actually learning anything in the process

That's why a systematic course like the unity pathway one is better.

[clear seal]

you mean call shoot = true and then false?

[ashen wind]

canShoot is a bool that you can use to check if the cooldown is up or not

[clear seal]

exactly

[ashen wind]

in the coroutine, it'll be set to false after you shoot, then the coroutine waits for the cooldown, then it sets it to true

[clear seal]

why would it be set to true if it's ended

[ashen wind]

the coroutine doesn't end like a normal function

[clear seal]

how come

[ashen wind]

it will continue running in the background until the waitforseconds is done

the whole point of coroutines is that they don't end, they wait in the background for something

and then once that happens, they can end

but the rest of your code still runs while the coroutine is waiting

[clear seal]

but from what i have understood is

can shoot false => shoot => wait => can shoot true right?

[ashen wind]

yeah that's the flow control

and notably the other functions like update are continuously being called while wait is happening

[clear seal]

explain like i was a little kid cuz i dont understand

pls

[ashen wind]

in game engines, there's something called frames

[clear seal]

ok

[ashen wind]

it's kinda like a clock that ticks every second

[clear seal]

ok

[ashen wind]

except a frame usually ticks like 30 or 60 times per second

based on how fast your computer can run code

it varies

[clear seal]

ok

[ashen wind]

every time a tick happens, unity will call the Update() funcition, and any code you put in update will run

[clear seal]

ok

[ashen wind]

so that's why we put the code that checks if you hit the f key and then shoots in update, so it's checking as fast as it can for whether you pressed it

[clear seal]

ok

[ashen wind]

typically, code can only do one thing at a time. it runs each line of code in order. this creates a problem, because if we want it to wait 10 seconds, it will have like 600 frames where it's not running any code and your game will just be frozen

[clear seal]

ok

[ashen wind]

so there's two ways to get around this problem. the first is just to write down the time that has passed in update and only allow the player to fire if the time that has passed since we started writing it down is bigger than 10 secs

[ashen wind]

that's what I was doing here

just writing down how much time has passed by subtracting from the cooldown how much time has passed since the last tick

[clear seal]

hold i will be back just going to unity deltatime learn video

[ashen wind]

ok

To get the colors, you write cs after the first backticks

[ashen wind]

that looks right

this could be an else:
if (cooldownTimer < 0)

but that's just style

it should function properly

[clear seal]

ok

i will test

[ashen wind]

the other way to do this is with the coroutines

[clear seal]

does this

work?

the way i did?

[ashen wind]

I find using timers to be more beginner friendly because you can see what the code is doing

but the community prefers coroutines, probably because too many cooldown timer variables can clutter up your code and make it confusing to read

[clear seal]

thank god i have been struggling with coroutines for a week now

[fierce geode]

Anyone got any piece of advice for moving along normals? I'm trying to make a character that can move around a vertical loop, it works all good until he reaches the part of the loop that sticks vertically upwards, then he starts moving downwards; it happens even with no gravity so my best assumption is that it has something to with how the velocity is being applied to the rigidbody,

currently, I multiply the left and forward velocity by the transform.rotation.
The only things I do with the transform rotation is rotating it so that it sticks upwards following the normal of the ground using Quaternion.LookRotation.

[clear seal]

and i forgot what was the goal 💀 😭

[ashen wind]

I didn't understand coroutines until I took a cs course that taught me about threading

basically the concept that computers can only do one thing at a time

[fierce geode]

Here's an example

[ashen wind]

and coroutines are a special workaround to get around that limitation

so it's effectively like multiple computers are running side by side in your computer

[clear seal]

do you have the link for the courses?

[ashen wind]

it was a course I took in my college on java programming

but if you look on the internet about threading I'm sure there are good explanations somewhere

[clear seal]

i also take courses but paid one and yeah

[ashen wind]

I drew a sphere at the location of the world coords of the tile

and as you can see, it's super offset

reposting my question cause I'm still super confused:

you know in games where you place a building and the unplaced building hovers over your cursor until you click
I'm doing that, and the following code is supposed to make the unplaced cursor building snap to the grid cell that it's over

        Vector2 cursorPos = Camera.main.ScreenToWorldPoint(Input.mousePosition);        
        Vector3Int cell_coords = gs.tilemap.WorldToCell(cursorPos);       
        transform.position = gs.tilemap.CellToWorld(cell_coords);

the problem is, there's some kind of offset
the final transform position that gets set is wrong and ends up misaligned with the grid

[ashen wind]

the sphere in the center of the farm should be in the top left of the grid cell I'm pretty sure

and for some reason the CellToWorld function is spitting out coords that make no sense

oh nvm, i fixed it

it was a combination of the tilemap being offset from the parent grid and the rect transform having the pivot in the center

the two bugs teamed up and made it take way longer to solve

[sharp stirrup]

is setting a game object through a public variable in the ui faster than transform.Find()? or is there no difference at all. i imagine it would be

[gaunt ice]

Setting reference is mush faster than find

https://discussions.unity.com/t/which-is-more-efficient-gameobject-find-or-public-gameobject/162975/2

[sharp stirrup]

okay thats what i thought. i wasnt sure since it was done through the ui idk why i thought it might be slower lol thanks

[polar acorn]

[soft wren]

dc.rotateDuck(new Vector3(FirstPersonController.Instance.transform.position.x, dc.transform.position.y, FirstPersonController.Instance.transform.position.z) - dc.transform.position);
This may sound like a stupid question but I can't figure it out for some reason. This piece of code rotates the enemy towards the player. How would I rotate it away?

public void rotateDuck(Vector3 direction)
{
    Quaternion rotation = Quaternion.LookRotation(direction);
    transform.rotation = Quaternion.Lerp(transform.rotation, rotation, rotateSpeed * Time.deltaTime); 
}

This is how it rotates ^^

[eternal needle]

Should be fine to just swap the operation so you do dc.transform.position - everything else
Also your lerp isnt really a lerp, you may want to use RotateTowards or whatever the name is

[soft wren]

What do you mena the lerp isnt really a lerp?

[eternal needle]

Lerp = linear interpolation. T should be a value going from 0 to 1, while yours is just a constant (simplifying here since deltaTime is not a constant itself). The value is going to relatively be very small but let's say around speed * 0.01f at all times.
You want to use RotateTowards because you can have it rotate at an exact speed, while not overshooting.

With your lerp, you cannot guarantee it will move at a certain speed. If the difference between A and B is larger, it will rotate faster

[soft wren]

Oh alright so like this instead?

transform.rotation = Quaternion.LookRotation(newDirection);```

[eternal needle]

I was referring to the quaternion method
https://docs.unity3d.com/ScriptReference/Quaternion.RotateTowards.html

It's possible to do with vector3 but then you have to construct the quaternion afterwards anyways

[soft wren]

transform.rotation = Quaternion.RotateTowards(transform.rotation, rotation, rotateSpeed);```

so like this?

I have to convert the vector3 of the direction to a quaternion anyway

[eternal needle]

You still keep the rotate speed * deltaTime but yea looks correct to me. This should rotate an exact amount per second

[soft wren]

I think it's all working good now, it just rotates a lot slower now so I've bumped up the rotateSpeed value quite significantly

[swift crag]

https://unity.huh.how/lerp/wrong-lerp

[eternal needle]

I think the 3rd parameter is in degrees, so a value of 90 would be 1/4th of a full circle every second. 360 would be 1 full circle per second

[swift crag]

Correct.

[swift crag]

it causes framerate-dependent behavior

[soft wren]

Ahh so if i made the speed value 180 it would take 2 seconds to rotate 360 degrees

[eternal needle]

Yes, should be easy to observe this happening if you setup a quick test. I'd test with 180 degrees because 360 would be the same position

[soft wren]

Thanks for your help :), everything is working as intended now

[fierce shuttle]

Setting it through the ui or even a static class/singleton wouldnt be a barrier for speed, since a reference is stored in memory you always have direct access to it, whereas any "Find" call has to search a collection (your scene hierarchy for example) and check "is this index the thing your looking for?", (hopefully) eventually find the object and then return it, assuming you cache the reference after its found, then the speed difference would more-or-less be the same, but a direct reference in the UI means the initial search never needs to happen anyway

[mighty falcon]

yo

when inside of a script how do you referance the game object the script is a child of

[swift crag]

https://docs.unity3d.com/ScriptReference/Component-transform.html

the transform property gives you your parent

and you can ask for the gameObject property from that Transform

[mighty falcon]

alright

where should i start looking

to make an overlay that is locked to the camera

[slender nymph]

use a screen space overlay canvas

[mighty falcon]

can you elaborate

actually now that im thinking about it i would rather have the text dialogues appear infront of the npcs

[slender nymph]

read the docs

[mighty falcon]

is there a gameobject that contains text

you could also just tell me

but sure ill go spend 15 minutes googling and finding unhelpful information until im lucky enough to stumble apon something i can use

nvm

[slender nymph]

if it takes you 15 minutes to find any information about how to display text in unity then you really need to get better at using google. this discord is not a substitute for learning or using google, it is a supplement

[mighty falcon]

i just noticed the "legacy" in the ui thing which should solve my issues

[eternal needle]

This also isnt a code question

[vernal minnow]

How do you code audio into your game?

I'm assuming the audio components need something to let them work

[slender nymph]

wdym by "need something"? they can JustWork™️

[vernal minnow]

I can just add the file and they'll work when the game starts?

Alr, and how do you destroy an object (a gamecontroller) after its been set to don't destroy on load?

[slender nymph]

pass it to the Destroy method

[vernal minnow]

Sweet

[rare urchin]

Not sure why you showed the code.
Show the inspector of what you tried to drag in

If it is TextMeshPro, add
using TMPro
to the top of that script, and change the type from Text to TMP_Text

[rare urchin]

cuz it not my code

i just told chat to make code that when im click button just change Text on Text

Make/release a complete game - it doesn't matter how mediocre it is. Then focus on improving/substituting individual parts like hud/ui and whatnot, knowing that the game is at least complete already. Follow a tutorial if necessary.

[tall storm]

How can I get my enemy to go after the players position and if it touches the player then the player loses a life and the enemy dies

[vale karma]

If I make a few scripts for a state machine, should i make another script to get the input from the new input system? or should I split up the inputactions into there respective state?

[eternal needle]

i find its nicer to have the input just handled by one class. makes it a lot easier when you want to change something about how input is handled, and you only need to change one class rather than every single state

[tall storm]

I mostly need help with the enemy finding the player position and walking to him

[vale karma]

Okay, ill try it out

[eternal needle]

unity's ai (navmesh) is the quickest way of setting this up. as for getting the players position, you simply need a reference to the player's transform. You can get that however you like, possibly with it being some public info, or maybe even gotten through a trigger enter.

[tall storm]

alr

thanks

[tall storm]

Yo i kinda need some help again, I made the enemy move and stuff like that and now that i made a script to take out the players health i get this error

private void OnCollisionEnter(Collision collision)
{
    if (collision.transform.tag == "Player")
    {
        Destroy(gameObject);
        playerLogic.GetHit(1);
    }
}``` error is at playerLogic.GetHit(1);

[rich adder]

so playerLogic is null

[tall storm]

no, it isnt

PlrLogic playerLogic;

[rich adder]

error says otherwise

[tall storm]

using System.Collections.Generic;
using UnityEngine;

public class PlrLogic : MonoBehaviour
{
    public float health = 3;

    public void GetHit(float damage)
    {
        health -= damage;
        if (health <= 0)
        {
            Application.Quit();
        }
    }
}

this is PlrLogic

[rich adder]

where is assigned

[tall storm]

in the enemy script

[rich adder]

thats not assignment

thats declaring

[charred spoke]

I love the if health 0 or less just quit the whole damn game

[tall storm]

and how to i assign it

[rich adder]

how did you assign playerObj

[tall storm]

by dragging the player

oooh

[rich adder]

then do the same thing

[tall storm]

it doesent let me drag it in

[rich adder]

is one of them a prefab not in the scene?

[tall storm]

whats a prefab

[rich adder]

can you show inspector of what you're trying to drag in

screenshot it

[tall storm]

alr

[slate haven]

Hi, I am facing a strange issue, I basically want to Move the road (lane) towards a position after getting instantiated. So In the following LaneIncrease(), isLaneMoving bool becomes true, and so does the instantiatedLane gameobject gets assigned a prefab. But in the Update(), it doesnt get updated. I always get isLaneMoving = false, and therefore my lanes are unable to move.
Image
Image
The function LaneIncrease() is called by picking up an item, which itself has a script called PickupManager(), it calls the method of LaneManager by referencing

[rich adder]

It needs to be on a gameobject

you have to drag the gameobject with that script

[tall storm]

ooh i think i did it

[rich adder]

Enemy has a player logic?

[tall storm]

u told me to drag the gameobject

[rich adder]

if its a player script why did you put it on enemy

[tall storm]

idk

wait

im stupid lol sorry

i had to drag the player in the player logic

thanks

but the game doesent quit when 3 enemies touch me

[charred spoke]

Application.Quit does nothing in the editor

You either want to exit play mode or do something else

[tall storm]

ok thanks

[lean basin]

excuse me, why did my character stopped at that specific spot? it makes no sense.
The specific spot it looks like... in the edge of ... that thing.

hard to say without
knowing the movement script for starters

[tepid summit]

holy shit

unity does have vector4

its for colors

which makes sense

a color is RGBA

a vvecrtor 4 would have 4 inouts

[charred spoke]

https://docs.unity3d.com/ScriptReference/Vector4.html its just a vector 4

i know what it is

[tepid summit]

jesus

[vale karma]

i see the problem

it aint got no gas in it

if I already created a full script with only 1 bug in it, should I keep the script and change it to add a state machine or should i redo it from scratch but use it as reference?

[acoustic sun]

I am having issues with my coding. On Unity, its saying I made some mistakes but I am not able to identify the issue on Visual Studios

[rich adder]

please delete this its hard to read on DC, and send links

[rich adder]

we told you what you need to do

configure your IDE first

[vale karma]

@lean basin i think you have the same friction issue i do, have you added a physical material to your rigid body?

[acoustic sun]

Im trying to figure out how to configure it. I'm looking everywhere to find resources but so far, no luck

[rich adder]

we linked you to it

!ide

[eternal falcon]

💡 IDE Configuration

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

Select one:

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

[vale karma]

and do you get caught on it when your jumping?

[rich adder]

Click it

I suggested you temporarily remove the script with errors before doing the config so everything compiles properly @acoustic sun

do you understand how to do that ?

[lean basin]

There are no rigidbody, no Collider component so no PhysicsMaterial from my understanding. I'm using CharacterController.

[north kiln]

As has been stated too, you may need to comment out your code so Unity can compile and connect with your IDE properly.

Then you can uncomment your code and fix your (now highlighted) errors

[rich adder]

there is a lot going on here.. Start debugging
also I would do some ray checks make sure no lingering invisible colliders somewhere

[acoustic sun]

I checked on there, pretty much I did everything on there

[north kiln]

Is that a "pretty much", or a "I did"

[acoustic sun]

I did

[north kiln]

1. Making sure the external tools setting is set in Unity.
2. Making sure the Game development with Unity workload is installed.
3. Make sure you have no compiler errors by commenting out your code and letting it compile.
4. Try restarting VS by reopening it with Unity's menu: Assets/Open C# Project

[acoustic sun]

For 4. Its letting me reopen it with the unity menu

Am I supposed to get Github as well for this?

[lean basin]

hmm, there are no invisible collider.
I'm not sure what else to debug.
The character is on ground and is in running state and doesn't change at all, there is not really much going on, it doesn't even call SnapToBottom()

The specific spot where the character stopped and seem to be trying to shove it's body to the ground is when it's hitting half wall? like a wall in the front it that is not high enough.

[teal viper]

I really doubt you can "get GitHub"😬

Or anyone for that matter. So, no.

[acoustic sun]

Okay because I am getting GitHub Copilot norifications on my script

[rich adder]

maybe you installed it 🤷‍♂️

[rich adder]

You tried another scene ? is it only that spot or just any edge?

did you Debug.Log yourisGrounded

the built in CC one is kinda ass

would double check // Snapping logic also

also not sure what you mean by

I'm not sure what else to debug.
there isn't any debugging in here xD

[eternal needle]

It probably just has no where to move on that specific area. Im on mobile so it's hard to see exactly what your script is doing.
Usually a collide and slide implementation would be used to avoid cases like this.

[lean basin]

any edge that is in similar shape.
Hmm I tried to debug isGrounded (i mean the CollisionFlag) it stays grounded except when going downhill in a big slope but the code is stuck when Im going uphill.

unfortunately the SnapToGround() didn't get called at all during the time it got stuck. so... the snapping logic is not called.
But I tested the snapping logic, it worked as expected, it doesn't switch grounded state at all when the slope is not that big.

[lean basin]

The collide slide thing!! what is that?
In another game engine (godot) I would usually use move_and_slide() as opposed to move_and_collide() which will slide to avoid this problem. I'm not sure what is the equivalent thing to do in unity.

[eternal needle]

You would have to implement it by checking what object is in way, then project your movement

Honestly when trying it myself, it was still buggy or annoying in some odd cases. Your best bet is really just use an existing solution like KCC or just use rigidbody movement.

[lean basin]

KCC? is it this thing https://github.com/nicholas-maltbie/OpenKCC ?

or are there other more simple one?

[eternal needle]

https://assetstore.unity.com/packages/tools/physics/kinematic-character-controller-99131
This one

[eternal needle]

I believe I tried using the one you linked and it is really buggy in some cases. Player can get stuck after very quick testing

It definitely will take some learning to use, I dont even use it because I just wanted to setup something less bulky. I opted to just use rb movement

[lean basin]

that looked more interesting than the link I posted. Thank you for your suggestion!

[vale karma]

is it easier to manipulate my code with 1 bug in it to a state machine or should i start from scratch?

[teal viper]

Depends on your code and personal preferences

[vale karma]

im just makin a new one with a reference

whats a better word than 'look

public Vector2 MovementAction { get; private set; } is this a class or a variable?

[wintry quarry]

That's a property

[twin bison]

Hi guys.
I want to check in a OnTriggerEnter2D if the collision is in specific layers.
I found this post https://discussions.unity.com/t/using-layermask-in-ontriggerenter/216825
But this won't work.
LayerMask.NameToLayer isnt what i want because I already have the layers to check against in a _collisionMask variable.
The second answer also doesn't work:

void OnTriggerEnter2D(Collider2D other)
    {

        if ((_collisionMasks.value & (1 << other.gameObject.layer)) > 0)
        {
            _health.TakeDamage(10);
            print("Hit");
        }
    }

Ok the second answer works now. I don't understand the code and it feels a bit hacky. Is this a good way? Basically I want to create an all purpose Hurtbox I can attach to enemy or player and only collide with things I want to specify. For example the player should not collider with its own bullets.

This is a unity server, which uses c#

[nimble scaffold]

all are public

[eternal needle]

No they arent, it is private by default

[barren aurora]

i know, would be more nice if unity use a package manager, give you your packages you buy. But they dont.
So ... i ask for help.

[twin bison]

Awesome, thx very much. That site is very helpful 😄

[barren aurora]

void UpdateTimerDisplay()
{
timerText.text = "Time: " + FormatTime(elapsedTime);
}

Change this to :

  public void UpdateTimerDisplay()
    {
        timerText.text = "Time: " + FormatTime(elapsedTime);
    }

[nimble scaffold]

ok

[barren aurora]

try again, should work.
remember

Everything what is NOT Public, can be NOT acessed from outside!

[nimble scaffold]

ik

hey bro the error is still there

Assets\MyMadeScripts\RaceScene.cs(11,30): error CS0122: 'TimeTrialManager.EndTimeTrial()' is inaccessible due to its protection level

using UnityEngine;

public class RaceScene : MonoBehaviour
{
    public TimeTrialManager timeTrialManager;

    void OnTriggerEnter(Collider other)

        if (other.CompareTag("FinishLine"))
        {
            timeTrialManager.EndTimeTrial();
        }
    }
}

[burnt vapor]

Please share the code containing EndTimeTrial()

[eternal needle]

Just curious, is your ide configured? Also save your other script

[nimble scaffold]

i use sublime text

[eternal needle]

This is why we dont spoonfeed answers 😅

Ok well, dont

Use a real IDE

[nimble scaffold]

vs code

[burnt vapor]

Please use a proper !ide for using Unity, we can't/won't help users without a misconfigured IDE

[eternal falcon]

💡 IDE Configuration

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

Select one:

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

[barren aurora]

my foult. Was because i am in other things with my mind.

   public  void EndTimeTrial()
    {
        timerText.text = "Time Trial Finished!\nElapsed time: " + FormatTime(elapsedTime);
        // Add any additional logic for time trial completion
    }

[burnt vapor]

Please read above, don't help users that have a misconfigured IDE

[nimble scaffold]

now i saves both the scripts

[eternal needle]

stop spoon feeding too. The guy didnt even understand how to fix the error after your first "fix"

[burnt vapor]

And there you have it, the suggestion was completely ignored since the initial issue is now resolved

[barren aurora]

can i ask what a "Misconfigured IDE" is ?

[nimble scaffold]

suiiiiii

the error is gone

[burnt vapor]

Lack of syntax highlighting, no proper error handling by the IDE, no quick fixes by the IDE

[nimble scaffold]

thanks to @barren aurora and @eternal needle

[eternal needle]

Go get a proper IDE and get it configured. You really shouldnt have been spoonfed the answer. Also I'm surprised you dont have one configured since I've definitely seen you ask questions here before.

[barren aurora]

Maybe.
BUT

i start same way.
You learn by doing.

Did you ever think about, that the Situation to put "Content" in TONS AND CONTAINERS into the Mind of a Guy who only want to know, how to fix an error

is contra Productive ?
if he want to stay, and countinue, and to better up his skill, he will learn.
but you do not help him, for a singel short Question, if you "Pusch 1000Ths Sides of Code" inside his mind, for such a small question.

this bring ppl to go away, not to learn things
here is best Example.

i startet, with the Question "how to collect a trigger"
and be BOMBED with 10 000 C# Books ( i never read )
Today, i am in since 8 Years, i am C# Pro, and have much complicatet Unity Projects.

BUT I WOULD NEVER START TO READ 10 000 Side Documentations
For a short Question!

[burnt vapor]

That's a lot of words

The problem is that rather than explaining the problem you just give the updated code as-is, without explaining what went wrong

That's not learning

[eternal needle]

Honestly I dont even understand what you're trying to say with half of that. It is a requirement to have a configured IDE. I also have taught students, you spoon feeding answers is NOT how people learn.

If someone goes away by the idea of having to learn, they are not cut out for coding. That is the reality of it

[barren aurora]

see above:
i told him:

Everything what is not public, cant be accessed.
but no problem
I be on my way to go here.
Because:

Help can nobody.
So : your game, you rules, not my building place.

[burnt vapor]

I have a hard time reading this, sorry

[eternal needle]

None of that makes sense yea

[north kiln]

!warn 892828741443674192 As you have been told previously, you need to have a configured IDE to get help here. Sublime text is not a valid IDE. You can use VS Code, Visual Studio, or JetBrains Rider.

[eternal falcon]

electro_op has been warned.

[eternal needle]

You told him an incorrect answer. He used it. Error didnt fix. He came back, clearly not knowing what to do. You gave another answer directly.
Now he will come back tomorrow with another issue, without getting a proper system setup.

It was clear he thought methods were public by default, but now he wont learn otherwise.

[north kiln]

Luckily for everyone, if that happens they will be muted

[barren aurora]

Short and Deepl:
a beginner, who probably has only one code error in an asset, will hardly read 10 C# books and start looking at millions of Toturials.

You're more likely to scare them away.
But: that's not my problem, I asked here briefly, no one likes can want to help, I'm already gone again.

Have a nice day.

[north kiln]

Nobody is asking them to read 10 books and look at millions of tutorials

they're being asked to configure their IDE and learn the basics

[nimble scaffold]

Ok

[tepid summit]

no colliders?

[barren aurora]

Yes, the first mistake was mine. I set the wrong method public.

My goodness, this is the beginner channel.
YES ! as a pro you always say. learn it right.
But you want to have fun with Unity first, not study 10,000 documentations.

He probably imported an asset and it has an access error. If he keeps at it, he will learn. But overwhelming him with books and confusing documentation is the opposite of fun.

Get something right first.
Then see where the problem lies.
How many get in and are out again after 2 weeks?
Does everything always have to be so doctrinaire? that's ... very fun-killing.
Especially with such a simple request, it's not a complex script. You helped him faster than you explained the documentation to him. hm ?

Stay human, always a good choice

💪

[barren aurora]

Yes, I understand you too.

We've all been through it at some point.
You know, I started with Udemy.
in the first "WEEK!" Toturial, I didn't know how to take 10 arrows from another collider. It wasn't explained there.

Then, when I asked in a forum, they all hit me with half 10 year courses. That is: absolutely counterproductive! Today I have extremely complex projects, so comprehensive that you wouldn't even want them to be true.

I learned everything myself.
But nobody has been able to help me with a book. You have to gain experience first. This : is the start.
You can turn a blind eye to that, can't you?

NOTE: nobody new even knows what an IDE is.
Even I don't know that.
just as a remark, and my things work wonderfully...

Also, the whole issue was related to a basic c# feature and not Unity. Stuff like these should be know if you start with Unity. Beginner Unity is not beginner c#

Stuff like this can be learned from tuts that can be found in the pinned messages

[vale karma]

is using localEulerAngles better than localRotation = Quaternion.Euler?

[languid spire]

they are identical

[lean basin]

no Collider in the character object. CharacterController provide it's own capsule collider which we can't edit like normal Collider

[eternal needle]

If your issue was the physics material I wouldve pointed it out before. The person who mentioned it is also a beginner. The physics material would be an issue if you were moving with rigidbody movement. The character controller basically teleports your player, while solving for depenetration meaning it wont get stuck in objects.

[north kiln]

NOTE: nobody new even knows what an IDE is.
Even I don't know that.
just as a remark, and my things work wonderfully...
Luckily the message that is sent when configuring it is requested lists them. Google tells you what they are, and so does asking.
If your IDE is also not configured then that's a fundamental and massive issue you should address before proceeding

[barren aurora]

Yes, but only.
It's a newcomer! Don't make such a big elephant out of it.
I don't use "IDE" for me it's Unity Editor, and Visual Studio. That's it. I don't like abbreviations.

and overall, he could save his script, and he was helped. So he seems to have a working IDE.

But good now. I helped him, why don't you stone me for it? A community where someone helps someone new. How can he.

Let's hit him with rules, requirements and compulsory events that he'll never understand as a new member, so that we can have fun and he's not helped.

And now: stone those who help a newcomer.
Hail community, the master has spoken.

In all seriousness and without irony: I'm off again, I've got other things to do.

[rare basin]

what you said

just doesnt make sense

i don't use IDE - i use Visual Studio 🤔

[icy grotto]

hi, can this one be converted to a Ternary operator?

[rare basin]

yea

act1SkillImgs[0].color = skillUnlocked1 ? Color.white : lockedColor;

[north kiln]

It's against our rules to give answers to people who do not have an IDE configured. Being able to save is not enough, you need autocomplete and error highlighting. If you want to continue complaining about these basic requirements you can write a blog, because they are not changing

[icy grotto]

Thank you so muchhh!!

[barren aurora]

Short: i use VStudio, this IS an ide, BUT i dont call it this.

nobody knows this "Short words"
here in germany we tell this DBDBHKP
also nobody know.

[rare basin]

everyone knows what an IDE is

what are you talking about

[north kiln]

I do not use visual studio

Others don't either, hence we use the word that refers to the group

[rare basin]

every programmer that knows the basics, knows what an IDE is (well even not programmers)

[barren aurora]

@rare basin @north kiln

Shortly:
The question was awnsered.

and i have other things to do, than to talk about IDE or not IDE,
or to waste my time, with "rules" for nothing.

it was just 1 word to change
the problem of the guy is solved.

That s it.
it is that easy, truly. it is.

[rare basin]

Then stop talking about it rather than constantly saying you are "out" but yet you aren't

[north kiln]

Go away then, please

[barren aurora]

just i was away, you did start again.

Just; it s completly not senceful, to discuss how about to call an IDE,
it s not simple.
it just wastes time.

and also all what i did say:
it was 1 word to change
no need, to avoid to help others, just because they should read tons of sides.
This is not nice for a noob.

stay familiar
and be nice guys.
This is just a noob, want to play around with Unity.
maybe, he can stand by us, or you make him crazy with 10 000 rules
and he stop.

think about.

What's the best way for me to use a random sound clip when something is triggered? I don't want my enemies punches to all sound the same. This is what I've got at the moment, but it's only player the first clip, never the 2nd

[rare basin]

Random.Range for int is exclusive

(1,2) can only generate 1

(0,4) can generate 0,1,2,3

[north kiln]

!warn 176068058241171456 it's a requirement that newcomers configure their IDE, and we do not want people to answer their questions to avoid time wasting. Your argumentative attitude is unwelcome and unhelpful. If you don't want to follow our rules you are welcome to leave.

[eternal falcon]

smokingheadstudio has been warned.

[west sonnet]

so I should change it to 1, 2 , 3?

[rare basin]

as i said, it is exclusive

so adapt it to the knowledge

[ivory bobcat]

If Statement:cs if (condition) result = first; else result = second;Ternary:cs result = condition ? first : second;Note that ternary requires the first and second results whereas an if statement doesn't necessarily require any results (nothing has to be done in an if statement).

[west sonnet]

I'm not entirely sure what exclusive means. It means it doesn't include the last digit?

[rare basin]

yes

it's a range from A to B, where B is exlusive

[west sonnet]

Does you know why it's exclusive?

[north kiln]

So you can simply pass an array length without requiring subtraction

[rare basin]

to align with typical behaviour with arrays i guess

[icy grotto]

Thanks!! ❤️

I have one more serious question before I leave again, because: I could always help myself without this channel 🙂 And I'm quite happy about it when I see this but:

How do you know if it has a configured IDE ?

that's the crucial question.
Because a C# code says nothing about it.

[rare basin]

experienced dev can just tell that by looking at code screenshots

code not auto completing, different types coloring, no errors highlight

[barren aurora]

Red error is red error. Do not tell you what Editor is saved for unity.

[north kiln]

Lack of highlighting, saying Miscellaneous Files in the top left of VS, a mass of stupid errors, posting screenshots of compiler errors in the Console window, an inability to connect the debugger.

Also poorly formatted and aligned code

[barren aurora]

Yes, well. Don't make an epic program out of it.

I've got other things to do than argue.
I helped one, that's it. His problem is solved, done.

Your playground, your rules.
And as far as I'm concerned:

I'm off again.
Play a little more. Fortunately, I know how to help myself. For almost 9 years now.
But where I don't ask - I now know 🙂

hehe. well then 🙂 Have fun.

[rare basin]

Delusional 😄

Keep programming without your IDE configured

have fun

When are you "finally" off?

[ivory bobcat]

An unconfigured ide would usually yield minor mistakes like missing semicolons, incorrect/invalid syntax from lack of auto complete (no awareness of available members), typos, improper text indentation on some text editors/ide and a whole lot more. It's like identifying if someone wrote their own code or use illogical ai code.

[barren aurora]

yeah. 20 Databases,
more than 2000 GameObjects scriptet
60 FPS
errorfree.

i go play again 🙂
see you

[rare basin]

Wait, you are programming for almost 9 YEARS NOW

without your IDE configured?

the fuck did I just read

somebody mute this troll lol

[ivory bobcat]

Not trying to say anything but anyone who brags probably hasn't been coding long enough yet.

[rare basin]

he's coding for 9 years

2000 game object scripts, no ide configured and 60fps

[barren aurora]

Note:
Things must - work -

I don't care what you mean by a "configured IDE". Ergo: I don't read through what garbage is written there if everything works perfectly.

If I encounter a problem, I solve it.
It's like patterns: yes, they can make sense.
But code is code, the result has to work.

As long as your car runs, there's no reason to rewrite everything just because you don't like the way you capitalize variables.

... just think about it.
The result speaks for the work.
Not the form.

[ivory bobcat]

I mean, if you've code from the 80's, 90's or even 2000's you'd know tech comes and go... everyone's always learning.. "pro", what's that?

[rare basin]

you are missing entire concept of having your IDE configured, at this point i think you are just a trolling kid tbh

so im done talking

don't spam the channel with offtopic now

but this is not the point.

Just: to help each other is the point, and not to discuss long terms

Can you send a screenshot of your IDE to this channel lol

[rare basin]

i'd love to see some code sample

from your complex project

could you send it?
