is it possible to write on the same line a <summary> of a var/function/... ?
something like c# /* <summary> is player on the ground </summary>*/ private bool _isGrounded = true;

knotty sun
#

so where do you initialize them?

knotty sun

then no

Well guess i'm gonna have to use my settings system to get this value instead

west hamlet
#

Thanks!!

#

Yeah i shoudl have used my settings system for that a while ago

#

works fine now

#

Now i still have to fix all the issues caused by me switching to 3D chunks

#

Uh it was easier to do than i thought

  • Will unity json utility serialize list null values? I.e. if i serialize a null, obj1, null, obj2 array, will it be deserialized exactly like this? If so, does it serialize nulls like in classic json by just typing null or by pasting empty objects?
cosmic rain
#

It will serialize these elements with default values.

how was it on none when you send a screenshot where it was enabled when i asked if you had it enabled?

#

refering to this

#

honestly if you serialize json

#

just use json library

#

unity serializer is dogshit

#

my experience with unity serialization is "don't use unity serialization"

Now Its fixed which is nice

Hey so im trying to make a transparent and click through background in unity but also make the ui works so the click through turns off when i have my cursor on UI. But for some reason its neither transparent and neither click through.

Yes.

then it is null by default

Let's say I want to create a helix pattern for my projectile trajectory. I do give these projectiles a duration so I was thinking of basing this change through a curve, so I guess the question is: would it make more sense to change the direction directly or perhaps change the rotation over the duration.

#

Actually, not too sure how to represent the direction on a curve hmm

#

I guess I'd have a curve for each axis then

fervent furnace
#

a circular motion+an additional "forward" vector
(if you look at the parameterized form of helix it does what i say)

#

the forward vector should be the some multiple of unit cross product of two radius vector anyway

latent latch
#

I was thinking of ways to generalizing projectile motion so having a one-curve solves all was a solution I was looking for, but it may just make sense to add an additional circular motion curve along with a forward velocity curve

fervent furnace
#

or the forward vector can be the normal of plane, then having a radius vector rotate on the plane, it should be the thing you looking for but idk the math

latent latch
#

I feel like I should just rewrite my whole projectile system now that I've got a better idea how to generalize a lot of this stuff instead of hard coding specific functionalities

in your usage you dont need to set null, only pass null

Hello. I want to update this script, I want to make it in the script so that when I activate 3 levers the door animation is played, but I don’t know how to do this, can anyone help me update this code for this.

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

public class LeverScript : MonoBehaviour
{
    public Animator Lever;
    public Animator DoorUp;
    public GameObject openText;

    public AudioSource openSound;

    private bool inReach;
    private bool doorisOpen = false;

    void OnTriggerEnter(Collider other)
    {
        if (other.gameObject.CompareTag("Reach"))
        {
            inReach = true;
            if (!doorisOpen)

I have a unit value kg•m/s². I am computing this value during an update cycle. To convert from second to delta time, do I multiply this value by deltaTime or deltaTime²?

fervent furnace
#

is it dp/dt?

#

or m dv/dt, it is quite weird that directly change dv/dt to ds

#

Does anyone have experience with Photon Fusion? I'm struggling with a basic scene setup. The spawned players work fine and FixedUpdateNetwork is called for them, but any objects which are in the scene before players spawn do not call FixedUpdateNetwork for me

#

I can provide more information on my implementation if necessary, but afaik Fusion should hook up the objects in the scene automatically since they have a NetworkObject component

verbal grail
fervent furnace
#

you

verbal grail
#

What is dp?

fervent furnace
#

momentum, usually denoted by p

verbal grail
#

The unit written out is as follows: kilogram * meters per second²

#

I add force to a body during an update, do I just multiply it by deltaTime or deltaTime²?

leaden ice
#

and put it in FixedUpdate instead

#

where it belongs

#

and multiply it by neither

fervent furnace
#

the physics engine will changing its velocity by adding F/m*dt (depend on forcemode)

verbal grail
#

ForceMode.Acceleration

#

It is in fixed update. I was asking hypothetically

leaden ice
#

is this a gravity force?

fervent furnace
#

you dont need to multiply it by anything, acceleration wont take m to account

verbal grail
#

Yes it's gravity

leaden ice
#

Or what

#

Then just do rb.AddForce(gravity, ForceMode.Acceleration)

#

assuming your gravity is expressed the same way standard gravity e.g. 9.8m/s^2 is

verbal grail
#

No. I am making a space simulation where bodies are attracted to each other's gravity fields based on their mass and distance from each other.

leaden ice
#

then use the default force mode

#

rb.AddForce(calculatedGravityForce)

#

it's ready to go

verbal grail
#

So to be clear, you are saying that AddForce will take into account the fixed delta time for me?

leaden ice
#

yes

fervent furnace
#

i remember there is energy conserve way to do work instead of just v=v+a*dt but i really forget what that calls.....

leaden ice
#

When using the default ForceMode.Force, yes

verbal grail
#

Awesome. That's all I need to know thanks guys

verbal grail
# leaden ice When using the default ForceMode.Force, yes

Some bodies will have a mass that exceeds rb.mass limit of 1e+09. So I have a custom component that stores mass as a double. Then it computes the gravitational attraction between bodies. So using ForceMode.Force will not be accurate because I need it to ignore the rb mass value. That's why I use ForceMode.Accleration.

#

Does this mean the fixed delta time is not considered in the AddForce method?

#

If so, what do I need to multiply my attraction unit by to make it fit into the time step?

fervent furnace
#

acceleration is v=v+force*dt

green oyster
#

(i added the if statement)

#

because the coroutine still ran after the script was disabled

#

or componenent

knotty sun
#

yes, it will, you have no loop in that coroutine

green oyster
#

i just thought that the coroutine would stop after the script was disabled lol

#

but nope

knotty sun
#

no, it will pause on the first yield, then it will continue on the next Update, disable and destroy happen after that

green oyster
#

tbh i dont think i know what it means by yield either, i just know i have to use it in coroutine to wait for seconds

#

and such

somber nacelle
#

are you sure this component is the one being disabled? 🤔

green oyster
#

yes absolutetly

#

adding that if statement fixed it

somber nacelle
#

and that if statement is checking a bool on a different component though

green oyster
#

yes, basically, egg hatches itself after a set amount of time

#

basically, i break egg, and i disable the component that spawns something once eggs broken.

#

but because its in a coroutine it didn't seem to stop, even after the componenet was disabled.

rigid island
#

where is the code question

round violet
somber nacelle
# green oyster but because its in a coroutine it didn't seem to stop, even after the componenet...

ah okay, so apparently disabling the component doesn't actually stop it. but destroying the component or setting the entire gameobject to inactive will stop it

public class TestThing : MonoBehaviour
{
    private void OnEnable()
    {
        Debug.Log("Enabled");
        StartCoroutine(CoroutineThing());
    }
    
    private void OnDisable()
    {
        Debug.Log("Disabled");
    }
    
    private IEnumerator CoroutineThing()
    {
        Debug.Log("Coroutine Started");
        yield return new WaitForSeconds(10);
        Debug.Log("Coroutine Ended");
    }
}

first set is enabling the component, then disabling the component. it still completed. second set was enabling the component then disabling the entire gameobject, it did not complete

image.png
green oyster
somber nacelle
#

no

green oyster
#

maybe, are coroutines just creating new threads to run code?

somber nacelle
#

it's still on the main thread

green oyster
#

oh

#

i dont know then why it doesnt stop, on disabling the script

knotty sun
#

I already told you

somber nacelle
#

actually what you said isn't quite right. it turns out that just disabling the component doesn't stop the coroutine at all

knotty sun
#

it will stop when it hits the next yield

carmine lagoon
#

Does anyone know how to make a volume slider?

knotty sun
#

IN THIS case there isn't one

    while(true)
    {
    Debug.Log("Loop Started");
    yield return new WaitForSeconds(10);
        Debug.Log("Loop Ended");
    }
}

disabling just the component does not stop the coroutine. only disabling the entire gameobject appears to

thanks

green oyster
somber nacelle
#

dunno, i guess it's somehow tied to the active state of the gameobject rather than the actual monobehaviour 🤷‍♂️

#

or maybe it's a bug

knotty sun
somber nacelle
knotty sun
#

lol

green oyster
#

lol

knotty sun
#

even so if you disable the gameobject any running coroutine should run until it's next yield before it is disabled

somber nacelle
# green oyster lol

anyway, either that if statement you already have or just calling StopAllCoroutines in OnDisable should do the trick to ensure that the destroy and spawning code doesn't run if the component is disabled

green oyster
#

which could have unwanted side effects

somber nacelle
#

nope, only on the monobehaviour you call it on

green oyster
#

Ah

somber nacelle
#

you could also store the returned result of StartCoroutine in a variable and pass that to StopCoroutine if you want to ensure you only stop the one, but in this case since you only have the one running on that behaviour StopAllCoroutines will work just fine

Hello, when i put Time.deltaTime in if statement, it struggling. When i remove the if statement, it's works right. Any reason for this?

I don't think just one condition can do like that.

#

The property has 4 references, inspect all of them

dusky pelican

#

The Inspector does not update as fast as your code, so the check box might not visually change if the underlying boolean is modified quickly.

#

3 more places where it's accessed to go.
Check the references to the bool property, not that method

dusky pelican
#

One reference

simple egret
dusky pelican
#

I changed it

#

After you said

#

Now like that

#

One reference, only changeable in editor

simple egret
#

Now check everywhere you modify CurrentConstructionTime. You might be subtracting deltaTime there, but adding some other value elsewhere.

dusky pelican
#

Nope 😦

simple egret
#

Check the value by logging it with Debug.Log instead, the inspector isn't reliable for fast change checking

Heya, I am using Mixamo character and the following weapon models https://assetstore.unity.com/packages/3d/props/guns/guns-pack-low-poly-guns-collection-192553

However, when I import the pistol, it is massive and in addition it has this odd pixel effect when model is moving around in the scene (Anti Alising?). I can fix the size by changing the scale factor but how do I fix it from having these odd weird lines when weapon is rotating in the scene? (Look at the left one vs the right stationary one)

I use URP btw.

I am trying to understand the logic behind but...

#

Whenever i tried to add [field:SerializeField] to my property and set the value from the inspector, timer struggle.

#

But in this way, i can set the value from inspector and timer working right

#

Just asking, what's the difference between of these?

somber nacelle
#

the only difference between the targeting the backing field of a property and having an explicit property with a get only property exposing it is where you assign to the field in your code. with the former the assigment happens through the property because there isn't an explicit backing field, only the compiler generated one. with the latter the property is read only so you have to assign to the explicit backing field

#

wdym by "healthier"? they are functionally the same

dusky pelican
somber nacelle
#

you haven't actually described your issue and i'm not going to go through and watch several videos to figure out what it is. but realistically there should be no impact on your code's performance or functionality when using a property with a private setter versus a private field

dusky pelican

you cannot use dynamic variables as arguments to a case

you can only do that in switch expressions, not switch statements

My code runs liquid fast, but now that I'm trying to assign a mesh to a Mesh Collider at runtime my FPS tanks thanks to this calculation that runs. This only happens once when I set a new mesh to a mesh collider, and after all chunks are done generating the FPS recovers. Can I get around this in any way? Some calculation I can disable, or do asynch instead?

use debug logs to determine the cause of the issue. Debug.Log the result of your ground check, and also log something in your if statement to see if the input is working. You could also log your velocity after jumping to make sure it's within the expected range

I'm am a having time of it trying to get PhysicsMaterials to work with my custom PlayerController.

General Info

  • Running Unity 2023.3.0a18
  • Using InputSystem
  • Script located on Player Object
  • The player Rigidbody does not use drag, and is NOT kinematic.
  • Player mass is 75 (assuming mass is kilograms)
  • Player has PhysicsMaterial with 0,0,0 so that the player can jump when running into walls.
  • Player has CapsuleCollider
  • Ground Detection is done with a RayCast

Below is a trimmed down version of the HandleMovement() function I am using.

    private void HandleMovement() { // Called in FixedUpdate. Handles WASD movement only
        Vector3 moveDirection = transform.forward * _moveInput.y + transform.right * _moveInput.x;
        float speedMultiplier = 1f;

        Vector3 targetVelocity = moveDirection.normalized * (moveSpeed * speedMultiplier);

        if (IsGrounded) {
            // On the ground, set velocity directly
            _rb.linearVelocity = new Vector3(moveDirection.normalized.x * targetVelocity.magnitude, _rb.linearVelocity.y, moveDirection.normalized.z * targetVelocity.magnitude);
        }
        else if(airStrafeForce > 0){
           // In the air, apply velocity with air strafe
           ApplyAirStrafing(targetVelocity);
        }
    }

Notice I am setting the velocity directly (not calling _rb.AddForce()). I am doing this as it was the best way I could get responsive input.

My question is that I would like to get a sort of ground friction set up. As an example, if I were to put ice on the ground, then it should take time for the player to work it's way up to the defined walk speed, and when the player stops walking, it should take time for the player to slow down and eventually stop.
One attempt was to place a PhysicsMatieral on the Ice, however, in its current state, my code does not respect this.
Another attempt was applying drag to the player when it was on ice, however, this just limits the max speed of the player.
Finally, another attempt was to build my own sort of friction, however in doing this, I feel like this is simply not the way to do it.

How can I allow for friction to be applied to player when the player walks on said surfces, while respecting my want for instant movement like in the code above?
If using PhysicsMatierals is the way to go, how should they be setup to allow the behavior I am looking for?

PhysicsMaterial would only work if you let unity physics to handle the velocity.

Hey all! Placing 2.5d trees on my terrain as quads instead of planes pushes them into the ground, changing this through the prefab does not do anything:

#

Can I code smth to fix this? Or is there a different fix?

hushed ore
# cosmic rain If you set the velocity manually, you would also need to calculate friction and ...

I ended up trying to use the _rb.AddForce with VelocityChange and I got it very close to how I was looking for it.

private void HandleMovement() {
        Vector3 moveDirection = transform.forward * _moveInput.y + transform.right * _moveInput.x;
        float speedMultiplier = 1f;

        Collider ground = GetGround;
        PhysicsMaterial groundMaterial = ground?.material;
        float frictionCoefficient = (groundMaterial?.dynamicFriction ?? 1f) * (1/3);

        Vector3 targetVelocity = moveDirection.normalized * (moveSpeed * speedMultiplier);
        Vector3 currentHorizontalVelocity = new Vector3(_rb.linearVelocity.x, 0, _rb.linearVelocity.z);

        if (ground != null) {
            Vector3 force = (targetVelocity - currentHorizontalVelocity) * frictionCoefficient;
            _rb.AddForce(force, ForceMode.VelocityChange);
        } else if (airStrafeForce > 0) {
            ApplyAirStrafing(targetVelocity);
        }
    }

This now respects the PhysicsMaterials present on anything players can stand on, but I am having to use only (1/3) of provided value for the player, otherwise it makes game objects that are controlled by the Unity Physics engine way too slippery. I'm not sure if this is the best way to handle this overall...

Is there a code maybe that can change all the rotation interpolation in the rig bones from quartanion to Euler Angle?
I have a complex rig with tons of bones and I need to change it Euler Angle for the animation to play well in constant interpolation.
and what I'm doing now is to select bunch of bones and than change all the from quartanion to euler angle but it takes quite a lot of time.

your center pos is right here
GenerateRandomPosition

#

just pass the correct square size in the params of overlap

#

if its blocked run the GenerateRandomPosition again until you found empty one

#

Ideally a loop to keep retrying

west hamlet
#

It needs an angle as a parameter

#

But I dont use any

#

you can put 0 then

#

also spawn your enemy as Enemy
GameObject newEnemy = Instantiate(enemy);

skip doing GetComponent 3 times

        newEnemy.transform.position = position;
        newEnemy.GetComponent<Enemy>().targetDestination = player;

        newEnemy.GetComponent<Enemy>().playerHP = playerHp;```

```cs
Enemy newEnemy = Instantiate(enemy);
        newEnemy.transform.position = position;
        newEnemy.targetDestination = player;
        newEnemy.barManager = soulBar;
        newEnemy.playerHP = playerHp;

you should prob have an Init method anyway..

public abstract class ATestClass : MonoBehaviour
{
    protected virtual void Awake()
    {
        // abstract awake logic here
    }
}

public class MyTestClass : ATestClass
{
    protected override void Awake()
    {
        base.Awake();
        // awake logic
    }
}

I'm creating an abstract implementation for a singleton monobehaviour. For the initialization, I need to have logic in the "Awake" method of the abstract class.

But this creates an issue in my eyes. If the singleton inheriter wants to run Awake logic, they have to override the Awake in the base class and run "base.Awake()" before their awake logic runs. This means the client has to know the base class's implementation, which is bad for code structure.

Is there any way to avoid this? Like seal the awake method on the base class somehow and create a virtual OnAwake() method that runs instead?

loud wharf
#

Yeah pretty much.

#

No other way.

#

Make Awake not virtual and make another method OnAwake that's abstract.

delicate olive
loud wharf
#

That's valid too.

#

There's just one problem you can't deal with though.

delicate olive
#

Also if I make the Awake method not virtual and private, can't the inheriters still implement Awake() by accident and have no errors pop up and it will fail hiddenly (or sumn)?

loud wharf
#

Yeah I have no idea how unity will deal with it.

fervent furnace
#

you will hide the base class awake

loud wharf
#

Yeah but idk how unity will decide which Awake to call.

delicate olive
#

Or maybe add a summary comment in the base implementation with bold characters saying "DO NOT IMPLEMENT! USE OnAwake INSTEAD!!"

#

Also sorry for caps

loud wharf
#

I heard that it prefers the new Awake from the class, not the hidden one from the base class.

delicate olive
#

Wait let me test

vagrant blade
#

It uses the one in the class it's called, and you can use base.Awake() to run the base class implementation as well.

delicate olive
#

Oh yeah it does not show the summary comments

delicate olive
#

See the post above

vagrant blade
#

I use a generic Singleton class that my managers inherit from. It uses Awake to make a static instance as well as call an empty virtual Initialize function.

Any manager that wants to be a singleton inherits and uses the Initialize function instead of Awake.

delicate olive
vagrant blade
#

It's never failed me

fervent furnace
#

you dont need to know anything of base class implementation indeed
you dont need to know how unity inplement monobehaviour behaviour component object when you use it

vagrant blade
#

And the whole boilerplate of creating singletons is nicely hidden away

loud wharf
#

I think his problem is people can accidentally create a new Awake and override it when the base Awake needs to be called.

#

Another idea I have is instead of just making a singleton monobehaviour, make it a normal object instead and require people to make a monobehaviour wrapper for it.

Yeah that would work too but often the wrapper is copy-pasted which is bad for code structure

Is it possible to send custom udp packets? I'm using NetworkTransport#Send, but this causes unity to complain:

[Error  : Unity Log] [Netcode] Received a packet with an invalid Magic Value. Please report this to the Netcode for GameObjects team
```Is ``NetworkTransport#Send`` something that should only be used internally by unity? If I *am* allowed to use it, then what packet structure do I follow to make unity ok with it?

Whats the best way to detect if the mouse has moved up or down since started holding down mouse botton? Trying to drag a gear handle but only if mouse button is held down. I have preset positions set using the "gearStage" IDs to line up with would positions.

if(handOnStick) {
    if (Input.mouseScrollDelta.y > 0) gearStage++;
    else if (Input.mouseScrollDelta.y < 0) gearStage--;

    if (Input.GetMouseButton(0)) {
        Vector2 mousePos = Input.mousePosition;
        if (Input.mousePosition.y > mousePos.y) gearStage++;
        if (Input.mousePosition.y < mousePos.y) gearStage--;
    }
}

Scroll wheel works like a charm. Just isnt as immersive.

You have to store the initial mousePos on GetMouseButtonDown, not every frame the button is held down

i am trying to understand timing of Start. Exactly when does Start get called? I’m noticing for monobehaviour A, A.Awake() / A.OnEnable() is called followed by B.Update(), followed by A.Start().

im trying to build my project with html5 and its crashed twice while building
the project works fine and ive built it for pc and html5 before

hard viper
#

how does that timing work with other scripts?

rigid island
west lotus
hard viper
#

like, should it be guaranteed that no Update()/FixedUpdate() for any script gets called in between Awake() and Start() of a given script?

dusky quest
leaden ice
#

Think of the Unity engine code doing this:

if (!HasStartBeenCalledYet(script))
  script.Start();

script.Update();```
dusky quest
#

and i had to use task manager to close unity

hard viper
#

oh, so Start waits for its own first Update()/FixedUpdate() call to call itself?

#

meaning if I Instantiate monobehaviour in one script’s LateUpdate (or something late like collision callback), then the instantiated behaviour will definitely not get its Start() until next frame?

dusky quest
leaden ice
hard viper
#

thanks. I fixed my issue before already, but was reaching out for more understanding as to why what I did worked

Start will always be called before update for a given Mono, however the order for different monos is not guaranteed, unless specifies in the execution order manager

Hi,

So I have my player who steps on a bus and triggers a collision. This way I can set the bus as my parent. but when I Set the parent (eitehr with SetParent, or just by setting transform.parent to the new parent's transform). I somehow keep my old local position, regardless of me setting it to Vector3.Zero

||I know, I'm using Xr Origin aka VR but I feel like it isn,'t VR related problem.||

Offset is a part of the bus which will be set to my current position which works fine. Then I set my XR Parent to that object. and set local position to 0. This seems to be doing what I expect in the object's code. but once the update happens, my local position is still the same, but the parent is set.

Does anyone know whuy this happens and how to solve this?

# supple relic Hi, So I have my player who steps on a bus and triggers a collision. This way ...

Have you tried the simple test of just, when you press a button, teleporting your character somewhere random in the game world? If you are unable to teleport, that likely means that either the physics simulation or the XR library is storing your position in some internal state and setting it every update. In other words, you would probably have to use some proper API to do a teleport like that.

supple relic
# stark plaza Can't you just change them to get more loot?

you can make them secure in multiple ways, one could be checking if it has been altered by adding some kind of value at the end that is a number representing all the data, if something changes, it won't match meaning data has been altered. Or you just hash it, also possible

supple relic

# stark plaza Thanks! Let's encrypt

some also make it binary, others make it a custom json file with a custom extention (though less secure I guess), I recommend you doing some research on what suites you best but there are neat ways 😄

hav'nt tried it when that exact event happens, so I'll try that, but just setting position does work

#

let me see

supple relic
#

nvm I didn't save my code...

supple relic
crude mortar
#

Hmm, seems suspicious! Likely there is some code somewhere using .position for movement calculations instead of .localPosition, and an internally cached .position is overriding your local position line on the next update.

supple relic
crude mortar
#

Well, if it's other code that's interfering, I don't think there is anything you can change in this code block that would resolve the issue. I am not an XR developer but my instinct is that it has something to do with the XR character controller.. You would know more about that than me.

evening folks! Im having a hard time with one thing: I have a method to read rb velocity and then feed it to the animator. Ive added some lerping there to make the transition smoother. It all works until i start feeding negative values. In the lerping process from -something, it jumps to +1.something instead of returning slowly to 0, thus making a weird jitter in the animation. I have it on screenRec, is it possible to post it here? Will gladly provide code. Thanks in advance! ❤️

leaden ice
#

how are you feeding the velocity to the animator?

#

velocity is a Vector3 (or Vector2) in 2D, and the animator doesn't accept vector parameters.

nimble hawk
#

Im aware, im going with magnitude. Code incoming:

leaden ice
#

magnitude can never be negative

hard viper
nimble hawk
# 

 void CalculateVelocities()
 {

     //Velocity
     Velocity = adWalker.CalculateMovementVelocity().magnitude; 
     if (Velocity == 0)
     {
         Velocity = stateMonitorScript.movementSpeed;
     }


     backVelocity = stateMonitorScript.movementSpeed * -1;

     if (Input.GetAxis("Vertical") > 0)
     {
         Velocity = adWalker.CalculateMovementVelocity().magnitude;
     }
     else if (Input.GetAxis("Vertical") < 0)
     {
         Velocity = backVelocity;
   
     }








   
     if (Mathf.Abs(Velocity) < rounder)
     {
         Velocity = 0f; // Set to zero if very close to zero
     }

     strafeVelocity = LerpStrafeVelocity();
     Velocity = lerpBackwardVelocity();



 }```
latent latch
nimble hawk
#

as for negative values:

  float lerpBackwardVelocity()  
  {

      
          // Check if moving backward
          if (Input.GetAxis("Vertical") < 0)
          {
              Velocity = stateMonitorScript.movementSpeed * -1;
          }
          else
          {
              Velocity = stateMonitorScript.movementSpeed;
          }

         

      // Lerp between current velocity and target backward velocity
      Velocity = Mathf.Lerp(Velocity, targetBackwardVelocity, Time.deltaTime * lerpBackwardSpeed);

      return Velocity;

  }```

leaden ice

definitely

nimble hawk
#

it is, isnt it..

leaden ice
#

so it's hard to give concrete answers

#

Also GetAxis has its own built in interpolation/smoothing

#

so that's adding some confusion here too

#

you can probably just do this to start with and get something smooth:

void Update() {
  float maxMoveSpeed = adWalker.CalculateMovementVelocity();
  Velocity = Input.GetAxis("Vertical") * maxMoveSpeed;
}```
And that's pretty much it - assuming you're feeding velocity into the animator directly.
#

GetAxis will provide the smoothness in this case

#

if you want to do your own smoothing - you should use GetAxisRaw and then smooth it with SmoothStep or MoveTowards

nimble hawk
#

I was thinking id pair the animator to the Veloc.magnitude, that would provide reliable numbers... boy, was i wrong 😄

if I have an auto property: [field:SerializeField] public int myInt { get; set; }
is there a way for me to easily keep the serialized backing field, and modify the setter to do something else?

supple relic
#

I did have a great idea of having an offset object, set it's localPosition the oposite of own position. but then i learned I also need to keep in mind the facing direction of the parent object of the offset, so I'll need to figure that out, but I guess this would be one way to solve it

crude mortar
supple relic
hard viper
#

well, I want to make it a full property, but keep whatever backing field values were already written in the project

#

maybe I should just write a backing field, duplicate the value in OnValidate, and just open every prefab with the given component in my project?

supple relic
#

Try calling the backing field from your propertie instead

crude mortar
#

If you figured out the name of the backing field, I think you could use [FormallySerializedAs] on a new variable that you create

supple relic
#

oh that way, yeah that coudl work

hard viper
#

so... how do I do that?

crude mortar
#

You can just look at the actual data on the asset files and see everything that's serialized

via a text editor

right now:

do I now make

public int myInt {.....// with full property ```
#

is that the idea?

crude mortar
#

That's the idea, yeah

#

You could test it with some other variables / properties first.

latent latch
#

at that point you might as well just use the getter

crude mortar
#

They are trying to convert an auto-property into a non-auto-property but keep the serialized backing field values

#

Since the data has presumably been authored on existing objects in the project and they don't want to get rid of that data

latent latch
#

you can do previously serialized as and switch to a private variable with the getter

hard viper
#

oh shit that works

#

I just tested it

latent latch
#

oh wait that's what you're doing

#

lmao

#

yeah that's one thing I dislike about the backing fields for that

hard viper
# 
[field: SerializeField] public int testInt { get; set; } 
// Replace with:
[SerializeField, UnityEngine.Serialization.FormerlySerializedAs("<testInt>k__BackingField")] private int _testInt;
public int testInt { get => _testInt; set => _testInt = value; }```
#

i can just retcon it. it was that backing field all along

latent latch
#

honestly it's such a trap to serialize the backing fields. My SOs are riddled with them and I do regret it a bit

#

looks cleaner though :)

hard viper
#

why would you not serialize the backing field

#

in the file, formerlyserializedas will not write over the old <xxx>k__BackingField entry, until you modify it yourself, then it will serialize it with its new field string

crude mortar
#

because seeing the real name for the backing field anywhere at all is gross

#

But if you never have to deal with the raw serialization, it's nicer

hard viper
#

you only deal with the raw name in the FormerlySerializedAs argument

In Input manager I have an action called CameraRotation which is returning a float +1 -1 upon pressing Q and E. I update the camera rotation in update. I have also by using getkeydown.q and e a 90° rotation upon the vertical axis but that is not performed in an update method. I switch this behaviour with a simple flag.
Since my action is called CameraRotation, do I really need to make another action for that?

#

And subscribe to the event upon pressing the button? Or can I do something smarter?

        else
            HandleSnappyRotation();
    }


    //called in update
    private void HandleRotation()
    {
        float rotationAmount = InputManager.Instance.GetCameraRotateAmount();
        [...]
    }

    private void HandleSnappyRotation()
    {
        if (Input.GetKeyDown(KeyCode.Q))
        {
            SetAngleOffRotationLeft();
            Rotate();
        }

        if (Input.GetKeyDown(KeyCode.E))

            SetAngleOffRotationRight();
             Rotate();

SetAngleOfRotation should be a single function

It is I just wrote some pesudocode on the real thing. Thing is both are called in update, both work with Q and E but one is using input system and the other not. I don't know if it possible to bind two buttons to the same action name with different behaviour on the same buttons

is there a way to group them together to aggregate them nicely and improve the data each one can work on or am I out of luck with that path

it shouldn't be an infinite loop since the if condition is only met if the boss is above 50% hp

my idea is:

phase 1:
melee attack
ranged attack
melee attack
ranged attack...

phase 2:
other attack 1
other attack 2

            tmp.AddRange(RecursiveSphereLookup(s.connectedSpheres));
        }

        return tmp;
    }

This recursive method takes a list of connectedSpheres and then concatenates each sphere's list of connectedSpheres into one master list.

The execution feels bloated and expensive. Any feedback on how I might make this method more efficient?

fervent furnace
#

is order important?

#

and is it acyclic? (not exists A sphere contains B and B sphere contains A)

nimble cairn
#

No, it is not order important

#

I don't understand the second part of your question!

#

Do you mean, does connectedSpheres list A contain sphere B, whose connectedSpheres list may contain reference to sphere A?

fervent furnace
#

yes, something likes that

nimble cairn
#

It is not then!

#

All List<Sphere> contain unique values to avoid stack overflow.

fervent furnace
#

do you know what is "graph" data structure?

nimble cairn
#

I have a vague understanding of this.

#

The current method does not "double up" when adding spheres to the list. I just test it.

fervent furnace
#

Ah, i just notice that you create a new list on each call, it can be avoided by a driver program or iterative approach

nimble cairn
#

Could you give me an example please?

fervent furnace
#

You can make a driver then turns this existing to helper , then the driver passes the list into helper and helper add the sphere to the same list in each recursive call
Void dfs(list l,A a){
l.add(something)
Dfs(l, other a in a)
}
Void driver(){
List l=new list;
Dfs(l, first a);
}

nimble cairn
#

Does that not have more overhead, being split into two functions?

#

And that method still creates a new temporary list.

fervent furnace
#

yes, you still need a list for storing all the results

void dfs(List<A> l,A a){
  l.Add(a);
  for other _a in a:{
    dfs(l,_a);
  }
}
List<A> driver(A first){
  List<A> theA=new();
  dfs(theA,first);
  return theA;
}
#

or the iterative approach by create an additional stack

nimble cairn
#

Okay I will put this on hold.

I have another question if you're willing:

I have a parent gameObject which has a Rigidbody component with gravity enabled.
Each child of the parent has SphereCollider and Rigidbody components with isKinematic set to true.
However, whenever gravity is applied to the parent gameObject, it fails to collide with anything.

Currently, my solution is to call Destroy(rigidbody) on each child gameObject until collision has been detected by the parent's rigidbody and then re-add the Rigidbody to the children after.

#

The children need rigidbody components for other game mechanics. However, this solution of destroying and adding components whenever the parent needs gravity applied to it just feels wrong.

crude mortar
#

Can you describe the mechanics?

nimble cairn
#

It's a bridge made of sphere gameObjects.

#

You can "pull" a sphere, to split the bridge into two.

#

Once a bridge has been split in half, the second half free falls.

crude mortar
#

I wouldn't recommend nested physics bodies in most cases. Sounds like what you want could be achieved via connecting the children with physics joints, or finding another solution for the "other mechanics" that you say require a rigidbody on each sphere.

#

If your reasoning for the children requiring a rigidbody is that nodes of the bridge (spheres) can be detached individually, why not just add a rigidbody after they have been detached?

nimble cairn
#

You're right, I've just scrapped the entire rigidbody system. Sometimes "reading your problems out loud" helps you realize why you're having bugs, lol.

@shrewd harbor With very limited information, you could include your "obstacles" prefabs which spawn in your procedural generation

#

The same way you might spawn a tree.

shrewd harbor
#

I don't really have the sprites yet but they will be part of the ground, and obstacles like Chrome's dinosaur

nimble cairn

Okay!

#

So you're placing the ground tiles along one axis

shrewd harbor

I'm oriented with this type of games

Screenshot_20231231_004036_A_GUY_The_Jungle_Journey.png
nimble cairn
#

Perhaps an int which counts how many tiles have been placed. And if you go over a threshold, you can place an obstacle.
This threshold could change based on your score, time survived etc.

shrewd harbor
#

Ohhh Okaay!

#

I think I know more or less where

#

Thx

nimble cairn
#

If you're using Unity's tile system, you just reference the tile one above on the Y axis where an obstacle would be placed 🙂

#

Tile system or not, I think tracking int tilesPlaced would be a good start

context: I have a class that consists of arrays of data points and I have an editorscript to edit and change these indivdual data points easily, but when instanciating a prefab with this script attached none of my changes I do in the editor stick

#

if the answer is they cannot, why is that? and what other workarounds could I use?

leaden ice
#

Of course they can

#

Follow examples

#

You need to be working through the SerializedObject interface and mark them as dirty etc

severe sable
leaden ice
severe sable
#

I can tell haha

leaden ice
#

Also make sure the data you're trying to save is actually serialized/serializable

severe sable
#

so I can't serialize my own datatypes

leaden ice
#

Of course you can

#

You can do all of this, it just has to be done properly

#

It's hard to say exactly what's going wrong without seeing any of the code though

severe sable
#

I can provide the offending snippets, one minuite

# 
            for (int i = 0; i < _nodeSystem.FreeNodes.Count; i++)
            {
                EditorGUILayout.BeginHorizontal();
                _nodeSystem.FreeNodes[i].Position =
                    EditorGUILayout.Vector2Field("Free Node " + (i + 1), _nodeSystem.FreeNodes[i].Position);
                if (GUILayout.Button("Remove Node", GUILayout.Width(100), GUILayout.Height(20)))
                {
                    _nodeSystem.FreeNodes.RemoveAt(i);
                }

                EditorGUILayout.EndHorizontal();
            }```

Should I be using DOTS and ECS even though the ECS is experimental or should I use DOTS and GameObjects

that really depends on the project

Well at the moment I'm making a 2D top down shooting game. I got to working on Pathfinding for the enemy AI and now I've gone into the rabbit hole of ECS. But becasue I'm new a lot of this stuff really goes over my head lol but I'm trying. So I've got a pathfinding algorithm in DOTS (A*) but don't know how to link it with my game objects

anyone had experience using aliases (symlinks) via git packages? the symlink is relative and works fine if i manually clone the repo to my computer, it just doesn't seem to work if Unity clones the repo via the package manager. the symlink itself doesn't seem to get cloned, but the meta file gets added just fine.

the package im trying to use is my own, so i'd really like to get it working.

You can use the other components (Burst and Jobs) with GameObjects, but using ECS means you have to restructure the whole project, since there are not GameObjects or components with ECS

Ok, you could look into using all of DOTS, but it's not recommended unless you need the highest performance or if you're a beginner

(DOTS is ECS, Burst and Jobs together)

#

The code you shared in #1062393052863414313 only uses Burst and Jobs and can integrate with normal GameObjects and MonoBehaviour

I'm a beginner tbh, but I have some background with C#. So how would I integrate gameObjects with the code I have now then?

you cant

#

job doesnt support managed type

you can feed the data from a managed type into it

you can feed data to it but you cannot use it in job

so wrap your data to struct and pass into it

you have already done this, you have created a struct and all you need is to initialize them then use it in job

I don't think so, since as far as I can tell(?) these aren't unity events, but something specific to colliders. If you want to make it easy, though, just make a simply collider script that executes a callback when a collisioni happens:

public class SimpleCollider : MonoBehaviour
{
  private Action _callback;
  private void OnCollisionEnter2D(Collision2D collision) => _callback?.Invoke();
  public void Initialize(Action callback) => _callback = callback;
}

public class ParentThing : MonoBehaviour
{
  // .. some init method - find all the SimpleColliders in all children
  {
      foreach (SimpleCollider myCollider in SomeListOfColliders) myCollider.Initialize(MyHandler);
  }

  private void MyHandler()
  {
    // .. handle one of the children collision events
  }
}
chrome trail
wise mesa
#

@knotty sun thanks ill take a look at it

modern creek
#

Yeah, there ya go. You could make it more robust by having the script ensure that there's a collider in Awake() or whatever, but that's probably NBD since the OnTrigger_ methods won't do anything if there's no collider.. but you know, for debugging

#

I would have naturally assumed there was a way to subscribe to collision events with something like colliderChild.onCollisionEnter2d += MyHandler but I couldn't find anything that supported that

chrome trail
modern creek
#

it might be possible but I cba'd to try 🙂

#

I'd probably do it the component way anyway since you're .. naturally gonna want to put some logic in the child collider over time anyway.. even some debugging hooks or whatever.. ie, "why is this bullet going twice as fast as it should be" type questions - you'd just slap a breakpoint on a bullet and debug it, instead of ... trying to mental-math it out from the parent

There is no guarantee for what the order will be, it can change if unity wants to change it. You can change the script execution order if really needed, but you shouldnt need this often at all. Ideally your code shouldnt rely on the execution order at all

Ya I was aware of these overrides, but hoping there way some overall pattern. Hmmm.

I have some component that generates a path (list of Vector3s). I was thinking of having other "Modifier" components that can hook into the path component and make alterations to it upon some event. I'm worried that if there were multiple modifier components, the order of them might end up changing the final result.

Your question's a bit vague. If you need to know how to store simple data points, look up "PlayerPrefs". If you need to be able to do something on a timer, write a method to check if that much time has elapsed and call it from an Update() somewhere in your codebase (probably related to player). If you need to save on demand when the app has closed, tie it to OnApplicationPaused() calls.

All good, just saying, your questions need to be a bit narrower. It's like asking "how can I get better at sports?" It's too broad and vague to give a simple answer. I gave you a couple leads to google up on. Just remember that when it comes to programming the things you do will be incredibly small until you're able to do them - how do I put a value into a variable, how do I loop over a bunch of things, how do I read text contents from a file, etc. Once you get those building blocks, then you can start putting them together to do things like build save system in a game in Unity.

You need an array of a serializable wrapper class that contains a list

gleaming tundra
#

How would the wrapper class work. Maybe I misunderstand the term?

hard viper
#

a wrapper class is just a class that basically holds another class, plus a bit more to justify its existence

gleaming tundra
#

That's what I did though, essentially

example; If an array did not have .Length, you might want to make a wrapper class that holds an array plus its length

foreach (Transform t in transform.Cast<Transform>().ToList()) t.DoThing();

Does this ⬆️ foreach cast calculate each time the loop iterates, the same way that the following loop ⬇️ will calculate the length of an array each iteration:

    DoThing();
}

Though, it will do it once

nimble cairn

@quartz folio I have a parent Transform and I iterate over each child and assign a new parent. I cast the children to a list.

If I don't cast the children to a list, the indexing will break

then use for loop and you use iterate it reversely

@gleaming trench You don't really need to use trigger collision to detect this! You already have a control variable hasBeenPickedUp!

Perhaps cast a raycast out, and then if there is a RaycastHit detection and you press E, then set hasBeenPickedUp to true.

#

Yeah, so rework the mechanic and don't use triggers.

nimble cairn

gleaming trench

alright alright i was just making sure idk its my first time using unity

nimble cairn

Not to mention, having a trigger box area takes more computational power than casting a raycast against a layermak.

#

@gleaming trench

if (Physics.Raycast(mainCamera.ViewportPointToRay(new(0.5f, 0.5f, 0)), out RaycastHit hit, X, itemPickupLayerMask) && Input.GetKeyDown(KeyCode.E)) {
    hit.transform.GetComponent<PickableItem>().hasBeenPickedUp = true;
}

Where float X is the distance of the ray. This could be Mathf.Infinity if needed.
Where LayerMask itemPickupLayerMask is a control layer so you are not casting a ray on every single surface on your game.

hi. im trying to make a ui pop up when you hover over an item/object in-game .i kind of got it to work but it only pops up when i hover over the leaves of the tree and not the trunk part. is this a skript problem or asset problem.

gaunt wren
#

@mossy sand just to clarify, you say the trunk doesn't work but the image you posted looks like it is.

mossy sand
#

sry

#

idk what is happening coz i tried it again to be sure but this happened

#

because when i look at the leaves i get the pop up. but then when i look away,say at the sky. the tree popup stays on the screen till i look at the floor of the trunk for some reason

gaunt wren
#

are the leaves and tree seperate objects by chance? Also, The text thing I suspect is because the raycast hasn't hit anything meaning it just keeps the original text from the last thing it hit

mossy sand
#

they are the same prefab

gaunt wren
#

well in theory, if it's a single object, the raycast should detect the whole thing. Leaves and trunk should be the same object but if it's not detecting the trunk, it suggests to me that the prefab consists of multiple objects and one of them(Leaves) is responding to the raycast.

Alright interesting question for yall. It might seem trivial but I don't think it is. I got this code for my navmeshagent. It's in my Update function.
if (navMeshAgent.velocity.magnitude == 0f)
{
SetRandomDestination();
}

The problem is as follows: If on frame X, velocity.magnitude is 0, it sets a random destination. The thing is that on frame X+1, despite having set a new random destination, the velocity magnitude might still be 0 (due to the agent not having its velocity caught up on the next frame yet), so the code repeats itself, if that makes sense. So at random times the agent will be stuck in place. Does that make sense? I have tried both Update and FixedUpdate but neither works. I basically want the agent to find a new destination whenever its velocity magnitude is 0. I want it to move all the time.

quartz folio
#

If that's not actually an issue in this case, perhaps also check the sqrdistance to the destination?

radiant elm
lean sail
radiant elm
#

it gets stuck randomly for like a few seconds. I could try every X seconds but that could still leave it stuck for that X amount of time

#

private void SetRandomDestination()
{
Vector3 randomPoint = Random.insideUnitSphere * 10f;
randomPoint += transform.position;
NavMeshHit hit;
NavMesh.SamplePosition(randomPoint, out hit, 10f, NavMesh.AllAreas);
destination = hit.position;
navMeshAgent.SetDestination(destination);
}

this is my desination code

#

There are no other navmeshes around, its only on a square platform

lean sail
#

It could even be something like 0.2 seconds or just check something related to the path to see when it's done rather than relying on the magnitude

Is there a way to prevent UI buttons from being triggered by keyboa...

Is there a way to prevent unity UI buttons from being triggered by any keyboard input? I only want them to respond to mouse inputs as keypresses are handled through code due to… reasons. Is there a way to do this with the inbuilt ui system or am I going to have to do some sort of raycast in trickery and have no onclick in my button?

you can open the input manager under project setting and the standalone input module in event system to have a look on it

So hey guys ,
I am working on a project on creating residential building procedurally in unity 3d .
as of the second step in that is generation of walls and roof.
while generating those I need them to follow Real-life physics and gravity , like when heavy loads are given to the floor it will break , it should be able to withstand earthquake, if proper stable widths and thickness for the walls are not there it will fall,

I have no idea on how to do these physics parts for this,

If anyone has any idea do help out .
reference documents and projects will eb helpfull

Hi all! Guys, help URGENTLY!!! The game is coming out soon and I still have this problem.
How can I make autosaving work when the player touches the trigger block? So that after exiting the game I can press the "Load game" button and so that I can continue the game from the place where the autosave occurred.

Is there a way to export grease pencil from blender into unity? I have a blend with a 3d model and grease pencil detail, but the grease pencil doesn’t carry over

then export it as an fbx or obj and you're done

Hey y'all, I made some tiny changes to my script from before, but for some reason, when rotating with EditRotation() (which is called in OnMouseDrag()), the object just jitters and acts weird when changing its rotation.

📎 AxisObject.cs
#

Could be hard to notice the objcet's rotation. No cursor capturing, Recorder don't like that hahah
But in the "Inspector", you can see that the Z is barely changing...

#

This script is put on the Circle you can see. Dragging around/with it, should change the Z of the track.... but it aint and i got no idea why 🥲

Heya, I am working on a 3D top down game and would like to have an illuminating vision cone. I tried using a spotlight to simulate this but it has some unwanted effects. Any suggestions on what is an appropriate approach to take?

Also I do not wish a viewcone that hides everything outside of the vision cone but just lights it up to some extent

can someone help me with scripting tile maps. I added this script to a gameObject and its supposed to make a tilemap and set a tile at the location of the mouse but it does not work. Everything just stays blank.

tilemaps need a tilemap renderer

foggy sentinel
#

i added that just now but it still doesnt work

crude mortar
#

they also need a Grid as a parent

#

(could be on the same object actually)

foggy sentinel
#

I also have that to

crude mortar
#

Oh I see, I missed the .SetParent line, my bad

#

what are you expecting to see? what's your tile look like

foggy sentinel
#

it should be this

#

I turned it into a tile

crude mortar
#

well all you are currently doing is setting the color at 0,0,0 to red and refreshing all tiles

#

you aren't actually setting a tile there

#

are you doing it by hand in the scene view?

foggy sentinel
#

I am doing in game

#

wdym by hand in scene view?

nothing in your code actually sets a tile

but I have set tile

oh wrong code

    }
}
crude mortar
#

still not setting a tile in the code though, just a color

#

you have to use tilemap.SetTile(mousePosition, tile);

#

and you shouldn't need to refresh all tiles each frame either (or at all)

foggy sentinel
#

it worked, It was the tile render and setcolor error

#

Thank you!

is this a good way to wait for a Coroutine to end in another Coroutine ?

        Coroutine cd = StartCoroutine(CountDown(3));
        yield return new WaitUntil(() => cd == null);

yield return CountDown(3)

  1. Don't use strings to start coroutines, StartCoroutine(fireBallDelay());
  2. if(canAttack); your if statement is empty because of the ;

Unsure how to best set it up.

how do i avoid this being true when the musicaudio is paused?

                yield return new WaitUntil(() => musicAudio.isPlaying == false && musicAudio.time <= musicAudio.clip.length-1);

and only when the music is 1 second from ending

quartz folio

#

I feel like the signal propagation can lead to loops really easily.

#

Am I making sense with this question btw?

quartz folio
#

Yes; the problems are probably in the details and specifics and general advice might not help; I've had similar problems making a custom state machine

#

it may be that Lague's was actually quite broken, but just worked for what they needed to do

#

and they never protected against loops

delicate olive
dawn nebula
simple egret
#

Yeah I guess each gate has an internal "have I been updated this tick" boolean that gets reset when a new tick is reached

#

Or they're stored in some list

quartz folio
#

Ah cool. I've not tried it myself but I would probably make a class that represents the electricity that collects the nodes it's enabled along its path. Then exclude those if I hit them in the same state, and perhaps count them too to avoid infinite loops

simple egret
#

Yeah requires some thought. You spent weeks on the thing, building a system that's really complex and think it's unbreakable. Then some user links a NOT gate to itself

dawn nebula
rugged storm

#

Stuff can still "loop" but at the defined tick rate.

#

I'm just worried about massive circuits.

delicate olive
quartz folio
#

That's also fine, if you did it in ECS it's very scalable

simple egret
#

You could define a max number of component updates per tick, and take back from where you were in the last tick

dawn nebula
#

I wonder how Minecraft does it with Redstone. Each piece of wire is basically a circuit component.

quartz folio
#

They have a tick; but that's one of the reasons it's kinda bad for certain things

#

I'm certain that how redstone works is heavily documented if you wanted to replicate it

dawn nebula
#

Honestly my use-case doesn't involve circuits that're THAT big. Even with ~a hundred components I doubt the performance would be that bad.

#

It would just be iterating down a list and checking a bool 😛

rugged storm
#

I can confirmed that simply calling musicAudio.Pause() causes it to evaluate true

this is the whole coroutine
#

its supposed to smoothly fade out from one song then to the next

delicate olive

But the -1 could for some reason be subtracting one from the bool, making it reverse and thus making it evaluate true when it shouldn't

rugged storm
#

it did not say it was redundant... lemme playtest

delicate olive

That's a good sign

rugged storm
#

it also does not fix the issue

Okay, do you know how to use an attached debugger?

jaunty sleet

Does anyone know what the best way is to get a random boolean value from unitys random class?

It randoms between 0 and 1, where 0 will be casted to false and 1 into true

jaunty sleet
rugged storm
delicate olive
jaunty sleet
delicate olive
#

Do Random.Range(0, 2) (2 because the second param is exclusive)

jaunty sleet
quartz folio
delicate olive
#

0 is false, 1 is true

rugged storm
delicate olive
#

Actually they maybe aren't ints because they don't need to use as many bytes in memory

quartz folio
#

Just == 1 to make it a bool

delicate olive
jaunty sleet
#

I just realized what I am trying to do is more complicated then I thought. I am trying to generate a random Vector3 with a magnitude in between a minimum and maximum value

delicate olive
# rugged storm somewhat at least

Then you should make the WaitUntil's anonymous function into a more debuggable form, so to something like this:

yield return new WaitUntil(() => 
{
  bool isPlaying = musicAudio.isPlaying;
  bool hasEnded = musicAudio.time <= musicAudio.clip.length - 1;
  return isPlaying && hasEnded;
}

and then inspect each of those variables in debug mode

quartz folio
jaunty sleet
#

No, it can be any direction

#

It's not normalized

delicate olive
#

And multiply by that random number

rugged storm
#

Oh ive jsut realized my issue i think,

i should have fliped the statment

what's the best way to implement repeating attacks for a 2d metroidvania?
edit: as in an enemy will repeat attack 1, then attack 2, then attack 3 and then go back to attack 1 (each attack needs to finish before starting the next one)

craggy veldt
#

this is if we're speaking about floats not int, which the op was asking

#

like maybe attack 1 will take 10 seconds to finish while attack 2 is fast and only takes 3 seconds

along with a few other checks
