[gray mural]

You should consider doing it in Start() I guess ??

[somber nacelle]

or even just in Reset

[fervent furnace]

i believe you will end up with error likes: layer value must be [0,31]...

[gray mural]

I don't think so

[gray mural]

and it does not throw any errors, just -1 if not found

[swift falcon]

Eh not a big deal, just an experiment

[gray mural]

Does somebody know if there is a possibily to do smth like:

private IEnumerator Bla()
{
    // do smth

    if (Bla() Coroutine was stopped)
    {
        print("Stopped");
    }
}

so that some action is done, when coroutine is stopped

[fervent furnace]

maybe pass a callback into it

[gray mural]

what's that?

[fervent furnace]

and no more yield return after the call back
Bla(Action something)
when finish, calls something() then "yield break"

[gray mural]

I actually didn't get anything, sorry

[swift falcon]

Specifically within the coroutine?

[gray mural]

no, it doesn't actually matter

[swift falcon]

You could maybe do something like

if (!coroutine.Running && coroutineWasRunning)```
I assume there's some IsRunning sort of thing, or maybe check if it's null

[gray mural]

oh, not that

[gray mural]

"unreachable code detected"

[fervent furnace]

while(true)

dead loop

[gray mural]

oh, yeah

any ideas how to stop it? 🤔

[gray mural]

I don't think that's what I need 🤔

it should do some action here:

StopCoroutine(_caretBlinkCoroutine);
_caretBlinkCoroutine = StartCoroutine(CaretBlinkCoroutine());

[swift falcon]

Why can't you just call whatever method after you stop the coroutine?

[gray mural]

I can

[fervent furnace]

If you force stop the coroutine i believe you can just call the callback right after it

[gray mural]

I just wondered if there's a better way to do that

[gray mural]

yeah, I wonder if I can though

[fervent furnace]

And the callback in ienumerator probably wont be called

[gray mural]

oh.

[buoyant crane]

IEnumerator One()
{
     yield return StartCoroutine(Two());
     callBack();
}```

One will yield until Two() terminates

[swift falcon]

Anyone know what this is stored as for a UnityEvent?

[SerializeField] UnityEvent<object> _event;

_event.Invoke(???);```

[gray mural]

I think I should test it. It should work with local Coroutine too I guess

[buoyant crane]

This goes a bit more in-depth: https://onewheelstudio.com/blog/2022/8/16/chaining-unity-coroutines-knowing-when-a-coroutine-finishes
Near the end it even talks about using callbacks.

[gray mural]

I think it is possible without callback too 🤔

[buoyant crane]

it’s completely optional

[lime widget]

I made a shotgun that shoots at the position of the mouse. I am having a little bit of trouble regarding the spread. This is the code I have. It works good for the most part but with this method the bullet spread depends on how close the cursor is related to my character. How can I make the spread independent of that?

        Vector3 mousePos = Input.mousePosition;
        var aim = cam.ScreenToWorldPoint(new Vector3(mousePos.x, mousePos.y, cam.nearClipPlane)) - transform.position;
        for(int i = 0; i < numberOfBullets; i++)
        {
            var dir = (Random.insideUnitSphere * spreadDistance + aim).normalized;

[solid mountain]

rotate towards, but like, for 2d? this is my code

        transform.rotation = Quaternion.RotateTowards(transform.rotation, q, rotateSpeed * Time.deltaTime);```

[hollow hound]

How to debug "The referenced script (Unknown) on this Behaviour is missing!".
Why it doesn't say what object/component is the problem?

[gray mural]

This code throws error, does somebody know if that's possible to do smth like that?

_caretBlinkCoroutine = yield return StartCoroutine(CaretBlinkCoroutineHelper());

[solid mountain]

it does some weird stuff, because it's for 3d and im on 2d

[solid mountain]

because someone forgot the semicolon

[swift falcon]

Anyone know anything about this? Going a little bit mad trying to find a workaround to what seems like a simple problem

[gray mural]

what?

[solid mountain]

yield return;(<-this thing)

[lime widget]

If you click on the error it will highlight the object that has the script missing. Check the components of that object

[somber nacelle]

StartCoroutine is part of that yield return

[gray mural]

no, I need to return Coroutine and store it

[somber nacelle]

they are literally calling yield return StartCoroutine();

[solid mountain]

ah, maybe then he should make it on the same line?

[hollow hound]

It doesn't hilgligh anything

[solid mountain]

i didn;t know, the most common issue is semicolon

[gray mural]

// works
_caretBlinkCoroutine = StartCoroutine(CaretBlinkCoroutineHelper());

// works
yield return StartCoroutine(CaretBlinkCoroutineHelper());

[somber nacelle]

it is, your discord window is just so small that it inserted a line break

[solid mountain]

ah

[gray mural]

it's not

[solid mountain]

it's not smol

[lime widget]

If you run the app, you get the error. Click on the error while the game is still running. If it stops automatically, be sure to toggle "Error Pause"

[solid mountain]

still anyone know something like RotateTowards but for 2d?

[hollow hound]

I tried cliking while game is on, while game is on pause and while game os stopped. Always no result

[lime widget]

Then idk 🙂

[wind palm]

It will in the log. Click the error and it'll say what line in what file

[lime widget]

I do this

var direction = target.position - transform.position;
var angle = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;
        transform.rotation = Quaternion.AngleAxis(angle - 90, Vector3.forward); /// the -90 was because my object was rotated weirdly

[hollow hound]

There is no message besides "The referenced script (Unknown) on this Behaviour is missing!".

[wind palm]

You need to read the error

[wind palm]

When you single click it, there will be a stack trace

[solid mountain]

ok ill try this ill try this

[wind palm]

Just under the log in a separate section

[solid mountain]

(this isn't c#?)

[wind palm]

This is c#

[solid mountain]

(i want it to move slowly, it is a missile)

[lime widget]

Good luck with that xd

[solid mountain]

bruh

[wind palm]

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

[solid mountain]

welp, time to show off that I am a good dev

and also die

[hollow hound]

There is no stack trace

[lime widget]

There is something like quaternion.lerp. Something like this

        timeCount = timeCount + Time.deltaTime;``` 
Try combining those

[wind palm]

I'm not on my PC right now so I cannot show you. Can you screen shot your console window?

Alternatively link the debugger to unity and then run it again.

[wind palm]

Perhaps you can use a tool such as:

https://www.google.com/amp/s/www.tangledrealitystudios.com/code-examples/remove-missing-scripts-programmatically-unity-with-code-example/amp/

Obviously I haven't tested it.

[hollow hound]

Thanks, I'll check it

[solid mountain]

oh my god I hate quaternions

[wind palm]

They're not that hard 👀

If I was at home I would give you my script for a turret

[solid mountain]

they are if you are working with 2d

[wind palm]

It's basically the same. You just need to remove the y rotation

[solid mountain]

and the x

i think

[buoyant crane]

not sure if someone already helped you fix this, but I believe you have to put it on separate lines

[wind palm]

Have you tried rotate towards?

[solid mountain]

i did, it was really weird on 2d

[leaden ice]

Vector3.RotateTowards using transform.right

[solid mountain]

hm

[swift falcon]

Anyone know if there's a way I can make Parameter serialized in the inspector?

[Serializable]
public class EventPlus<T>
{
    public UnityEvent<T> Event;
    public T Parameter;
}

[SerializeField] EventPlus<object>[] _eventPlusArr;```

Or if there's any way to invoke a UnityEvent<object> with the parameter from the inspector like in the image below:
```cs
[SerializeField] UnityEvent<object> _event;

_event.Invoke(???);```

[leaden ice]

E.g.

transform.right = Vector3.RotateTowards(transform.right, targetDirection, speed * Time.deltaTime, 0);```

[leaden ice]

Event.Invoke(parameter)

[solid mountain]

more hm

[leaden ice]

Hey you asked

[swift falcon]

Event like this?

[SerializeField] Event _event;```
Not sure I follow

[leaden ice]

Idk what Event is in this context

[swift falcon]

That's what you wrote

[quartz anchor]

How does physics.sphereCast get it's normal for objects that it hits? Does it return the normal of the face of the collider thats closest to the sphere's origin?

[swift falcon]

I'm looking for a way to use the parameter you can write into a UnityEvent from the inspector

Like the 5 from the image above

[leaden ice]

Using event from here

[leaden ice]

From the part of the collider the sphere hit

[swift falcon]

Oh right yeah the problem with that one is that Parameter doesn't appear in the inspector when T is an object

[solid mountain]

working! a million thanks

i have to study quaternions, whenever it comes on rotating i screw up

[swift falcon]

Seems like this is the only thing I can do but it's very ridiculous

[Serializable]
public class EventPlus<T>
{
    public UnityEvent<T> Event;
    public T Parameter;
}

    [SerializeField] EventPlus<float>[] _eventPlusFloat;
    [SerializeField] EventPlus<string>[] _eventPlusString;
    [SerializeField] EventPlus<bool>[] _eventPlusBool;
etc

            foreach (var eP in _eventPlusFloat)
            {
                eP.Event.Invoke(eP.Parameter);
            }
            foreach (var eP in _eventPlusString)
            {
                eP.Event.Invoke(eP.Parameter);
            }
            foreach (var eP in _eventPlusBool)
            {
                eP.Event.Invoke(eP.Parameter);
            }
etc```

[solid mountain]

what is this?

[leaden ice]

Don't really understand what you're trying to do TBH

[swift falcon]

A workaround because Unity won't let me use the parameter in the UnityEvent
I just want to do something like:

[SerializeField] UnityEvent<object> _event

_event.Invoke(_event.parameter);```
But there is no _event.parameter

[kind atlas]

hi I'm programming a health bar system that has a health bar with a shield bar over the health, similar to what you'd find in a fighting game. it mostly works but I'm having an error where the visual for the shield bar doesn't zero out before the health bar starts taking damage. the data is correct but the fill for the visual stops at 0.18181 leaving a part of the shield bar. both the shield and the health have identical code and the fill for the health bar goes to 0. I'm not sure how to fix this. the code is written across 4 scripts. This is where i got the original code from https://youtu.be/cR8jP8OGbhM?t=1077

Stat Manager - https://hatebin.com/tcjgbfklyz, Damage Manager - https://hatebin.com/dneuehugdd, Shield Point Manager - https://hatebin.com/yhsqnkfotd, Shield Bar Visual- https://hatebin.com/vgblqcsqcn

[swift falcon]

Ok you're actually joking Unity

eP.Event.Invoke(eP.Parameter);```
This does nothing with eP.Parameter. It just ignores it!
It instead uses the parameter you assigned in the inspector. It's what I wanted but like...what?
So the correct code is in fact

_event.Invoke(null);```
Insane

What's that got to do with code?

Hello! Why I cant access any namespace if I already have the package installed?

[heady iris]

https://docs.unity3d.com/Packages/com.unity.code-analysis@0.1/manual/index.html

The DLL in this package are not automatically referenced to your project's assemblies, so you will need to reference all of them in each .asmdef that will require them.

[versed loom]

the namespaces are referenced but i cant access the generator attribute

Hi is it possible to make an ingame microtransaction system with steamworks ?

cause for my game that uses steamworks a lot (online multiplayer fps) I think microtransactions are better than DLCs

[spare dove]

Best practice question; I have several different types of items inheriting from a base class, whats the smoothest way to check which type an item is?

[potent sleet]

maybe is, as or GetType()
?

if you have a lot of diff types instead of if statements or giant ass switch maybe is best doing lookup table with dictionary ?

[spare dove]

Yeah right now im using an " if item.script is weapondata"

[cursive gorge]

If I turn on gpu instancing from the material and turn on static batching from the editor, will they conflict?

or improve performance 2x

[abstract fern]

https://partner.steamgames.com/doc/features/microtransactions/implementation
Yes, bu you'll need to add a custom web server that acts as a middle man. The WebAPI can't or may not be used directly from the client (the WebAPI key that you receive should not be included in the build)

[vague jolt]

How do i finish decalring this:

    public class References
    {
        public List<GameObject> structures = new List<GameObject>();
        public List<GameObject> cables = new List<GameObject>();
        public List<int> connectedTo = new List<int>();
    }

    new Dictionary<string, References> references = new Dictionary<string, References>()
    {
        {"Red1",}
    };

To have the same workings of this mess

    //input red 
    public List<GameObject> connectionsRed1 = new List<GameObject>();
    public List<GameObject> cablesRed1 = new List<GameObject>();
    public List<int> connectionPointRed1 = new List<int>();

    //input green
    public List<GameObject> connectionsGreen1 = new List<GameObject>();
    public List<GameObject> cablesGreen1 = new List<GameObject>();
    public List<int> connectionPointGreen1 = new List<int>();


    //output red
    public List<GameObject> connectionsRed2 = new List<GameObject>();
    public List<GameObject> cablesRed2 = new List<GameObject>();
    public List<int> connectionPointRed2 = new List<int>();

    //output gren
    public List<GameObject> connectionsGreen2 = new List<GameObject>();
    public List<GameObject> cablesGreen2 = new List<GameObject>();
    public List<int> connectionPointGreen2 = new List<int>();

i just don0t know how to declare the value part of the dictionary

[steady moat]

new Reference() ?

[vague jolt]

thanks, but i guess you don't need the brakets

[steady moat]

You should review the name of your class. References is pretty bad name for what you are doing there.

[vague jolt]

why ?

is the list of all the references that my gameobject is storing to other gameobjects

what this rappresent is the connections in a network

[steady moat]

Also you might want to do this:

var dict = new Dictionary<string, References>()
        {
            {"Red1", new References()}
        };

[steady moat]

You named your class by its function in code instead of by its actual function. What the class represent ? Is it a player ? A node ? A bridge ?

It is like calling a class class.

[vague jolt]

so i should call it node ?

is tecnically a structure that is then joined to other structure using cables

here is store the connections

[steady moat]

I don't know. You know. You are the one creating the object.

It must have a purpose ?

[vague jolt]

why is this better btw ?

[steady moat]

I mean, it compile.

[vague jolt]

the reason i called it reference is because is litteraly storing references, or should i call it structure references to be more clear ?

[steady moat]

No, use the language of your domain.

What are you doing ?

[vague jolt]

can you be more precise with this question is a bit unclear

[steady moat]

What is red, green, blue ?

[somber wyvern]

Hello, does Unity have a specific owner client ID value to represent a null ID? I couldnt find one in the docs.

public NetworkVariable<ulong> CurrentInteractorClientID = new NetworkVariable<ulong>();

I have something like this to keep track of the client that is holding an object, but when its not holding anything, I am not sure what to set this value to. I couldnt find anything in the docs, so I am curious if you all have an answer

Im considering just using the max value for ulong but I dont know if unity has a specific recommendation

[vague jolt]

the color of the connection

each structure has two type ofg connections, red and green , the can be both inpuit or output

1 and 2 rappresent that, i know those are not clear but i can't really change it

[steady moat]

This is even worst

What if you decide to change the color ?

[vague jolt]

i won't

i can't

[steady moat]

Are you serious O.o

[vague jolt]

i am making a simulation of something that already exist

if i changed it it would be wrongh

same reason i use 1 and 2 is because the original game uses 1 and 2

[steady moat]

What if you decide to change the theme of your application

So, green is input ?

[vague jolt]

doesn-t really make sence because the sprites of the structure use green and red

[vague jolt]

nope

wait

[steady moat]

Is it red then ?

[vague jolt]

i send you an immage

[steady moat]

#archived-networking

[vague jolt]

left is imput, right is output

[steady moat]

The color has no importance there...

What is the function of the devices ?

[vague jolt]

this can do math

[steady moat]

Alright, so what the red cable does ?

[vague jolt]

you can use the inputs in the green and red cable and output it to the red and green cable

[vague jolt]

move data between structures

the reason there are two cables is so you can use the same id without the data adding togheter

[steady moat]

So, can we call it something like Link ?

[vague jolt]

sure

[steady moat]

So, a machine has link. This particular machine has two link. You do not need to identify those link inside the class don't you ?

You could have a list of link.

List<Link> instead of a dictionnary.

As you might have other type of machine in the future

One with more than 2 links

[vague jolt]

all the machine arte the same

they can have only 1 or two links

[steady moat]

Alright, I'm done. You understand nothing of what Software Architecture is.

[vague jolt]

i know what you mean, but because this is a simulation of a game that already exist there is no need to think beyond what the game already is

thanks any way

[steady moat]

And friend, this is where you are wrong.

[vague jolt]

why ?

[vague jolt]

like i am onestly curious, i not a good programmer at all, so if i can understand software architecture would be just better

[dawn nebula]

Does Unity have some built in Timer class with callbacks I can hook into?

[vague jolt]

there time.delta time

[somber nacelle]

depends on the purpose

and what kind of callbacks you are expecting

if this is for some sort of gameplay timer then no, although there is a timeSinceLevelLoad property on unity's Time class. you'd have to write your own using a deltaTime timer in Update or c#'s StopWatch class or something

[steady moat]

Software Architecture is all about minimizing change to increase the maintainability of a software. With the approach you are taking, you gonna have a hard time implementing the other functionality; Those that are in the game your copying.

To create a solid architecture, you must consider the concept you are representing. You must define what we call Domain-Specific Language (https://en.wikipedia.org/wiki/Domain-specific_language). In your case, that would Machines, Links, Input, Output, etc. If you do not define those concept, you never going to be able to have a stable structure as it will not represent correctly your application. Each Business Rule you gonna implement will always require a reorganization of your structure. You are already suffering from this and you are probably not far in your implementation.

[vague jolt]

bro is a wizzard

wizzards know everything

[steady moat]

Bro went to school and listened.

Those paper are not only for show.

[vague jolt]

i learned everything by myself 🧐 , so my code runs with spaghetti and tomato sauce

[steady moat]

This going to follow everywhere till you have the motivation to make clean code.

[vague jolt]

is something i always try to do but i don't think is something i can just figuer it out by myself indeed you have a degree for a reason

[steady moat]

Self taught is hard but not impossible. You just gotta look further then under your nose.

[vague jolt]

i am doing this project litteraly because of this, but the problem is that there are many many things to learn

i like learning by being forced to find solution other than studying the theory, at least for coding

[steady moat]

Alright, just stayy curious. Because the way you were earlier is the worst way to approach any issue you will have.

[vague jolt]

check this older code that know i am rewriting

💀

[steady moat]

💀

[dawn nebula]

Ya gameplay timer is what I'm looking for.

[vague jolt]

i guess what you could do is use time.delta time and count how much time passed, then when you reach the the time you want you call the function you want to call

[dense tusk]

'ello lads. i ripped off some code and did some experimenting with it, and i am confused by how a certain part of it works. it does work, but i don't understand how: https://paste.ofcode.org/AqUUYq7BnaqE7UvEDJ5YJw

in particular, it's the

//Sets a target position (tbh don't know how this works, but it does)
Vector3 targetPosition = holdPosPoint - selectedRigidbody.transform.position;
``` that i don't get. can anyone tell me what this is doing exactly?

[honest edge]

hey guys. Anyone know what's going on with "UnityException: Load is not allowed to be called during serialization, call it from Awake or Start instead." Got this since the new LTS. I just upgraded and this is annoying, even if it works in reality.

[dense tusk]

think that means something is being incorrectly assigned outside of start or awake

[honest edge]

you mean the substraction of two vector3?

https://docs.unity3d.com/ScriptReference/Vector3-operator_subtract.html

[dense tusk]

i guess that's the wrong part to focus on. i'm confused as to this is getting the correct location for an object to move.

[honest edge]

check this. there's an example for exactly that. pretty simple.

[dense tusk]

like, i get that it's subtracting the vectors, but i don't understand how that's getting me the correct position for what i'm doing.

[honest edge]

you substract both of these vector. this gets you the vectorial "distance"

You then change the velocity by using this distance and slowing going in that direction using time.deltatime

[buoyant crane]

targetPos = currentPos + someSpace;
someSpace = targetPos - currentPos;```
Does that sort of help?

[honest edge]

"targetPosition * forceAmount" is the same as the substraction but you multiply each of them by this number

to be honest, the example in the doc for velocity is very clear. You should look at it. It's the same thing but simplified:https://docs.unity3d.com/ScriptReference/Rigidbody-velocity.html

[buoyant crane]

the names don’t make that much sense in your code, but your result is the someSpace(difference) between holdPosPoint and selectedRigidbody.position

[honest edge]

this error is more annoying to me lol. Not sure if this is version specific cause I didn't have that in the non-LTS for the same code.

[buoyant crane]

try deleting the library folder and seeing if regenerating it removes the message

weird that it only created the error after you updated

[west lotus]

Aint no better Timer than this https://github.com/akbiggs/UnityTimer

[honest edge]

yeah. thanks. already tried that. didn't work.

[honest edge]

do you need something that fancy to time stuff? why not just using IEnumerator and yield?

most thing that requires timer, I just use a coroutine personnaly

[west lotus]

Well okey, but if you need to time lots of stuff you might as well create some sort of utility class

[honest edge]

this does look like a nice library though. avoid a few headaches for creating variables mostly. What do you need something like that for?

[west lotus]

And if you do that you might as well use a pre built and tested solution

[dawn nebula]

Damn that is a pretty nice library.

[honest edge]

My though as well. I like it even though I don't need it

your point is that it's not maintained anymore?

[west lotus]

My point?

Dude wanted a timer with a callback

i gave him a timer with a callback

There is no point here to be had

[honest edge]

oooh. I though you were asking the question lol. my bad

[west lotus]

We use this lib in our games and are very happy with it so I share it with people who need to time stuff

[honest edge]

this conversation suddenly make sense in my head 😂

thanks for sharing

[dawn nebula]

Hmm. Do the timers work across scene changes?

It doesn't seem like the TimerManager has DontDestroyOnLoad

[honest edge]

store the result between scene or something?

or just dont destroy one class in which you have it initialized

[west lotus]

Right. I think we made it a singleton a while back

Hello,
I am attempting to make a restaurant game and the npcs coming in are supposed to sit down (animation) after their transform being set to a gameobject's transform
For some reason there is always an offset on the y - Axis, I am not sure why
I am also unable to move the object's Y axis in runtime

Components:

Rigidbody
2x Colliders (one with, one without trigger)
Navmesh Agent
Script

Animator in the child object

private void OnTriggerEnter(Collider other)

        if (other.name == "WalkToPos")
        {

            nav.ResetPath();

            nav.updateRotation = false;
            Rigidbody rigidbody = GetComponent<Rigidbody>();

            rigidbody.velocity = Vector3.zero;
            rigidbody.constraints = RigidbodyConstraints.FreezeAll;

            StartCoroutine(CustomerSit(other.transform.parent.Find("SitPos").gameObject));

what's the best way to make an infinite looping scroll? I know there's assets but im trying to figure out how to do it myself. I initially tried doing an invisible "teleport" once I go past a boundary, but if I drag past, say, 0.8 and try to teleport to 0.2, dragging further will continue to take me past 0.8. then it just flickers because it tries to teleport again.

now I'm thinking of doing a dequeue system, but I still run into the same issue.

[gray mural]

no, that's not my problem

I need to yield return Coroutine (as you have said before) to wait until coroutine is finihsed and this coroutine should be _caretBlinkCoroutine

So it's possible to do _caretBlinkCoroutine = StartCoroutine(CaretBlinkCoroutineHelper());

and possible to do yield return StartCoroutine(CaretBlinkCoroutineHelper());

but this is impossible

and that's what I am trying to achieve:

private IEnumerator CaretBlinkCoroutine()
{
    _caretBlinkCoroutine = yield return StartCoroutine(CaretBlinkCoroutineHelper());

    IEnumerator CaretBlinkCoroutineHelper()
    {
        WaitForSeconds _caretBlinkRateWait = new WaitForSeconds(caretBlinkRate);

        while (true)
        {
            yield return _caretBlinkRateWait;

            ChangeAlpha(0f);

            yield return _caretBlinkRateWait;

            ChangeAlpha(1f);
        }
    }

    ChangeAlpha(1f);

    void ChangeAlpha(float alpha)
    {
        Color newColor = _caretImage.color;
        newColor.a = alpha;
        _caretImage.color = newColor;
    }
}

[honest edge]

you don't need the startCoroutine in an IEnumerator

[gray mural]

yes, but how do I assign it now?

[vale wren]

i have a bunch of buttons in a scrollrect, is there some way to reorder them during runtime

[gray mural]

set parents

[soft shard]

If you have access to "Content" you could use the transform.SetChild and GetChild, when you loop through with childCount in a for-loop, or a foreach loop if you prefer

[honest edge]

@gray mural What are you trying to achieve exactly? I might be missing the context of what you're trying to do here.

[gray mural]

I am trying to make it so that if you end Coroutine - it can say its "last words"

for example when I do:

StopCoroutine(myCoroutine);

it does something at the end (e.g. "bye bye" in console)

[honest edge]

do you mean StopCoroutine?

[gray mural]

yes, sorry

[honest edge]

In general, this is considered bad pratice to use stopCoroutine. Just because there's proabably a better way. You can't really know where the coroutine will actually stop. If you need a very specific behavior to happen, you won't have control over when it does stop.

controlling the when using variable or something else could be an option.

From what I get, you want to get your caret to flash once and then do something, right?

Why not in this case have a variable global to your class, call it "endCaret" or something. And in your coroutine, you have yield waiting for this to happen, and then trigger whatever you need.

yield return new WaitUntil(endCaret);

[soft shard]

If the endCaret variable is a Coroutine type, you should also be able to call something like yield return StartCoroutine(endCaret); or endCaret = StartCoroutine(...); yield return endCaret;

[gray mural]

this coroutine stops everytime user types smth in custom InputField.

caret is constantly blinking

and when coroutine stops - caret should imediately become visible (alpha 1f)

[gray mural]

it just calls coroutine twice

and it won't call endCaret = StartCoroutine(...); until endCaret Coroutine is not finished

[gray mural]

I wonder if that works with my while loop

[soft shard]

Really? Interesting, I was using something similar earlier today for a rebind system and some logging and seemed to only happen once, though I often have a function to manage coroutines with variables, something like:

Coroutine co;

void DoThing(IEnumerator next)
{
if(co != null) {StopCoroutine(co);}
co = StartCoroutine(next);
}

That wouldnt be the same as yielding it inside a coroutine though, just would prevent multiple coroutines from starting if the previous one wasnt finished (or reset to null) already

[honest edge]

that's already basically a while loop that checks for a condition

[honest edge]

so you have a coroutine checking the content of that field? or is that event based?

I feel like the solution to your issue isn't really a coroutine but simply an event.

If you have a class to manage that inputField, you should have a property for the content of it.

If you have something like this:

[ashen yoke]

just figured i could unload all the projects i dont need in the solution and hide them

instant vs speedup

[honest edge]

public event Action<string> OnInputChanged = null;
private string _input = "";
public string Input {
    get => _input;
    set {
        if (_input != value) {
            _input = value;
            OnInputChanged?.Invoke(_input);
        }
    }
}

Then, you call it where you need it:

Input.onInputChanged += Somefunction;
private void Somefunction(string value) {
    if (value==="smth") {
        StopCoroutine("caretAnimation");
    }
}

@gray mural Or that could be a simple function inside the set instead of an event if that's suposed to apply to any input whatsoever. litle less flexibility.

That coroutine could be on the class of the inputfield itself, and you could call it to start and stop the caret animation using the same technique.

[ashen yoke]

[placid island]

oh sorry

[gray mural]

Sorry for late reply. So that should work, yes. I was just considering to make this in one coroutine though, but this is great too. Thank you

[gray mural]

I guess no ?? This method is called by Event though

like this:

private void KeyDownEvent(Event evt)
{
    switch (evt.keyCode)
    {
        case KeyCode.Backspace:
            BackspaceKey();
            return;

        case KeyCode.Delete:
            return;
    }

    ValidateInput(evt.character);
}

private void ValidateInput(char c)
{
    if (c == '\0' || c == '\t' || c == '\n')
        return;

    text += c;

    AlignCaret();
}

[gray mural]

though I wonder why I need to use event here. Isn't it redundant?

@honest edge @soft shard thank you both for your help, that's the solution I have done after all:

private void CaretBlink()
{
    if (_caretBlinkCoroutine != null)
        StopCoroutine(_caretBlinkCoroutine);

    ChangeAlpha(1f);

    _caretBlinkCoroutine = StartCoroutine(CaretBlinkCoroutine());

    IEnumerator CaretBlinkCoroutine()
    {
        WaitForSeconds _caretBlinkRateWFS = new WaitForSeconds(caretBlinkRate);

        while (true)
        {
            yield return _caretBlinkRateWFS;

            ChangeAlpha(0f);

            yield return _caretBlinkRateWFS;

            ChangeAlpha(1f);
        }
    }

    void ChangeAlpha(float alpha)
    {
        Color newColor = _caretImage.color;
        newColor.a = alpha;
        _caretImage.color = newColor;
    }
}

[honest edge]

If you already have something to handle it, yes it is. It was just the idea

[royal pulsar]

I have this process that I want to handle

right now I do it via 2 scripts like this:

public class Interaction : MonoBehaviour
{
    public UnityAction onInteractEvent;
    private Transform aim;
    [SerializeField] private float range;

    private void Awake()
    {
        aim = GetComponentInChildren<Transform>();
    }
    public void Interact()
    {
        // Shoot raycast and return hit object (or null)
        RaycastHit2D hit = Physics2D.Raycast(aim.position, aim.right, range);
        if (hit)
        {
            GameObject hitObject = hit.transform.gameObject;
            TryInteractWithObject(hitObject);
        }
        onInteractEvent?.Invoke();
    }

    private void TryInteractWithObject(GameObject objectToInteractWith)
    {
        if (objectToInteractWith.TryGetComponent(out Interactable interactableObject))
        {
            interactableObject.TriggerInteraction();
        }
    }
}

Both scripts are the same except one does TryInteract and one does TryHit

how can I avoid this code duplication?

[regal epoch]

is there any way the basic unity ads can mess up a game? I had a working mobile game, and wanted to add the ads. but now its completely broken. the starting screen doesn't show text anymore and when i click the (only) button to start the game it gets stuck on an infinite loop clicking itself and doesn't start the game. tried looking into the logs with logcat but couldn't find anything

well i found the problem. it was the ads initializer i added on the starting screen. when i removed it, the game works fine. anyone would happen to know why?

[latent latch]

Well, first off, do you have a case where a gameobject is both hittable and interactable? If so, is there priority to what you check first?

[royal pulsar]

I don't plan to but if there is such a case, interaction happens via the E key while hitting is via Mouse1 so they won't have to be checked concurrently

I'm thinking of just splitting the big script into a Fire() script, a Raycast() script, and then I can apply either a Interact() or Hit() script

i feel like interfaces could be useful but im not 100% sure when to use them,

I can communicate the scripts via unity events

[latent latch]

Usually when I think of interact scripts, they are usually done without needing to know the exact derived type that's hit, and as such you just use the override methods of your implementations

[royal pulsar]

I see

To be honest my current scripts are purely compositional

[latent latch]

Interact keyword meaning that there's some sort of functionality that you can do with the object, either attack, talk, trade

[royal pulsar]

so my enemy is just a health component, collisionattack component, AImovement component. There is no concrete "enemy" class or anything

[royal pulsar]

Is this through inheritance?

[latent latch]

Yeah, via virtual function implementations

[royal pulsar]

ah i see, my project is just structured too differently

[latent latch]

not entirely sure of a composition or an ecs type of way

if anything, a switch of checks might be what you need

but this still comes to my previous question about having multiple interface types

though if you've got differeny raycast methods depending on input then that's not a problem

[celest moss]

Hey im trying to setup a position constraint for the purple aura in my game. But adding a new constraint source doesnt apply any constraint to the gameobject. I am confused on how to use the position constraint and untiy script documentation doesnt help me either

[latent latch]

I think there may be values you need to toggle with the constraints when you create one

I forget

It's like weight or something

[celest moss]

ah found it thank you

[rocky jackal]

how can i check if a bounding box of one object is inside the bounding box of another object ? im currently cecking it like this but it wont stop scaling down the object

[regal epoch]

it looks like your scaling it down when its not colliding

but i could be wrong

[rocky jackal]

im scaling it down when the second bounding box isnt inside the first one and it should theoretically stop once the second object has been scaled down enough to fit into the first object

its for an inventory system

[rocky jackal]

thats right

[regal epoch]

maybe put extra true statements in? right now you're checking if the first one is false or the second one is false. but not one false and the other true. so when they're both false it still runs the code

[rough crown]

vscode question. How do i move the "2 references" to the right?

[regal epoch]

it means it's used on 2 different locations in the code. here's a stackoverflow post that might help disable it
https://stackoverflow.com/questions/34356510/how-to-disable-codelens-in-vs-code

[rough crown]

oh so it's called a codelens

yikes so apparently they don't have the feature to move it to right like in intellij (illustrated below)

[ashen yoke]

disable codelens, use search in options

[ashen yoke]

we have a feature to remove it tho, best feature ever

[rough crown]

yeah couldn't look cleaner

[ashen yoke]

you should bind a hotkey to find references

[normal dust]

can anyone familiar with zenject help me make a dontdestroyonload singleton equivalent? i just picked up zenject and im confused to say the least ._.

[lethal tusk]

Is there a way to load all scenes once you open the game? There are some scene in my game with some script that I need to load as soon as the game launched. The reason is These scripts generate some data that I need on the first scene.

[normal dust]

thats exactly the reason Im asking for help here

[ashen yoke]

create an empty scene that does whatever loading you need

[normal dust]

you could put everything you need in the first scene and then load additive

[lethal tusk]

I cant really. is there another way?

[ashen yoke]

you can use RuntimeInitializeOnLoad

it has params that allow you to run code before scene loads

[lethal tusk]

I have an array of bools in one script, like this: public bool[] cubeList = {true, false, false, false};
and I save this to a json file, If i launch the game for the first time It makes a an array of bools without any value.

So the game wount work cuz I need those values

[ashen yoke]

create an empty scene, set it as the first, do whatever loading you need, then load from that scene the actual game scene

its a very common pattern

[lethal tusk]

sure thanks

[ashen yoke]

or use RuntimeInitializeOnLoad

[lethal tusk]

just one more question, I should use singeltons to share the data right?

[normal dust]

you could

[ashen yoke]

singletons are the most basic global access pattern, its always present in any game, in various amounts

should you? depends on your project and your skill level

there are alternatives that grow in complexity in an attempt to remedy the shortcomings of it

[normal dust]

mr cache do you know anything about zenject?

[ashen yoke]

yes

and container in DI has the same properties of a singleton

just hidden further

[normal dust]

so if i bind something to it, it should remain in the next scenes?

[ashen yoke]

refer to docs

🙂

which do you use?

extenject?

[normal dust]

yes

is there a difference?

[ashen yoke]

https://github.com/Mathijs-Bakker/Extenject#injecting-data-across-scenes

did you read this?

[normal dust]

i didnt but i read about project context so i thought the way to do that would be with it

i dont understand whats the use of the project context then

[ashen yoke]

im reading and i dont understand your issue

project context is already DDOL?

[normal dust]

I added it to my first scene and it doesnt seem to make another instance on the next scene

my problem is im trying to get my data from firebase and bind IDatabase to that instance and only then to load the next scene

[ashen yoke]

it says any scene that contains scene context will first load project context

after that it will singleton DDOL for the lifetime

[normal dust]

yea ik its project>scene>gameobject

idk why but these docs are very confusing to me

should i add the project context to my first scene?

[ashen yoke]

i dont know how extenject handles it, i dont think it needs to be present in any scene

[normal dust]

i dont think i should cause its a prefab

[ashen yoke]

it should be a prefab that is automatically instantiated

[normal dust]

yea so then how would i inject FromInstance

ive been stuck on it for hours chatgpt doesnt help unfortunately

[ashen yoke]

so your issue is that binds on project arent injected in scene?

[normal dust]

sound about right i think

from what i understand project context binds whatever i need once and thats it for the rest of the game runtime

[ashen yoke]

yep seems that way

are your scenes properly setup?

scene context present?

[normal dust]

thats probably where im not doing things right

in the first scene do i need a scene context?

[normal dust]

cause all im doing is binding to the project context (so far) and as you said ^^

i tried doing that with the database instance being ddol and loading scene additive both dont work

[ashen yoke]

validation passes?

[normal dust]

yep

[ashen yoke]

what happens?

nothing passed? null passed? db itself loads?

[normal dust]

public abstract class DatabaseDependant : MonoBehaviour
{   
    protected IDatabase _database;
    [Inject]
    protected virtual void Construct(IDatabase database)
    {
        _database = database;
    }
    protected abstract void LoadData();

public class CurrencyManager : DatabaseDependant
{
    protected override void LoadData()
    {
        print(_database == null);
        print(_database is null);
        Pawins = (float)_database.GetValueFromDatabase("Pawins");
        Pawllars = (uint)_database.GetValueFromDatabase("Pawllars");
    }

basically prints "True" at these debugs
NullReferenceException: Object reference not set to an instance of an object

[ashen yoke]

which line

alright, what calls LoadData()

[normal dust]

its called from start

[ashen yoke]

can you put a breakpoint in Construct and LoadData

see in which order they are called

and observe _database value

[normal dust]

i can but ill mention i even tried making start ienumerator and wait 5 seconds

and it still said its null

[ashen yoke]

then just in Construct

[normal dust]

mmkay

its totally different from breakpoints in normal programming one sec ill google how to do it in unity

[ashen yoke]

its the same, highlight the line in visual studio, press F9, press F5 to connect to unity, play in unity

[normal dust]

then nothing is happening

like it doesnt reach the breakpoint

[ashen yoke]

you arent hitting it?

[normal dust]

nope

[ashen yoke]

then you have something broken in zenject scene/whatever that mono is on setup

zenject ignores it

[normal dust]

do i need a scene context on that scene?

[ashen yoke]

possibly, it may be needed by zenject to indicate that scene scene is zenject enabled, maybe to perform scene initialization

most likely what it does is it loads first since its high in SEO, disables all scene objects before they have a chance to receive Awake, initializes/injects them, then enables

[normal dust]

so i have a projectcontext in my first instance with an installer on it binding from instance, and an empty scene context in the next scene and it says
ZenjectException: Assert hit! Tried to create multiple instances of ProjectContext!

maybe my whole approach is wrong how would i go about doing what i need

load the snapshot from firebase, bind that instance, load next scene and have it injected where needed

[harsh ridge]

anyone know how to detect when a vr player pulls a controller towards themself?

[steep herald]

not a VR dev, but I assume you can simply use the controllers XZ distance from the headset's XZ coords, ignoring the Y? If the distance delta over a certain amount of time is greater than your threshold, then make shiny things happen

Or, to ignore the potential bias caused by dragging the controllers ahead of you but towards the center of your body, you could figure out the forward vector that represents the facing direction of the player, negate that vector, and see how far the controllers have traveled along that vector

which I'm guessing the only harder part about this is determining the player's forward vector if it's not persistent in your game, and if there aren't libraries that already do this. Likely inferred from the controllers orientation and the headset's over a set amount of time

Yo, I have a question...
How do I save a 2D/3D array which is being generated by my AssetPostProcessor on a ScriptableObject so that's it available during game runtime?

[field:SerializeField]
public float[][][] array3D { get; private set; }

My method for generating the array is being called, but it's null at runtime

[somber nacelle]

unity does not support serializing multidimensional or jagged arrays so you'd have to store that data some other way

[wide dock]

Oh, I see..

[wide dock]

[Serializable]
public class MyArray<T>
{
    private T[] elements;
        
    public T this[int index]
    {
        get => elements[index];
        set => elements[index] = value;
    }
}

[field:SerializeField, HideInInspector]
public MyArray<MyArray<MyArray<float>>> array3D { get; private set; }

Would that be ok then?

[wind palm]

You're better off flattening the array.

public T this[int x, int y, int x]
{
    get => elements[x + WIDTH * (y + DEPTH * z)];
    set => elements[x + WIDTH * (y + DEPTH * z)];
}

Then your constructor would be something like:

public MyArray(int x , int y, int x)

Making sure to save the width, height and depth.

Then it'll save as a single array

[wide dock]

[Serializable]
public class MyArray<T>
{
    private T[] elements;
        
    public T this[int index]
    {
        get => elements[index];
        set => elements[index] = value;
    }
        
    public MyArray(int size)
    {
        elements = new T[size];
    }
}
[field:SerializeField]
public MyArray<MyArray<MyArray<float>>> generatedPattern { get; private set; }

public void GenerateAttack()
{
  generatedPattern = new MyArray<MyArray<MyArray<float>>>(repeatCount);
  for (int r = 0; r < repeatCount; ++r)
  {
    generatedPattern[r] = new MyArray<MyArray<float>>(inBatchBulletCount);
      for (int i = 0; i < inBatchBulletCount; ++i)
      {
        generatedPattern[r][i] = new MyArray<float>(batchCount);
      }
  }
  ...

[wide dock]

Oh. That also makes sense.

Thanks

[fervent furnace]

for accessing a[i][j][k] it should be i*sizeof(j)*sizeof(k)+j*sizeof(k)+k, the order of your indexer looks a bit different though it works but i j k have to be inversed

First I tried to generate cubes arround but every single one spawns on the same spot

private void GenerateCubes()
    {
        // Obtener la posición del GameObject
        Vector3 position = objetoActivo.transform.position;

        // Generar los cubos en las posiciones alrededor del GameObject
        for (int x = -1; x <= 1; x++)
        {
            for (int y = -1; y <= 1; y++)
            {
                for (int z = -1; z <= 1; z++)
                {
                    // Excluir la posición central
                    if (x == 0 && y == 0 && z == 0)
                        continue;

                    // Calcular la posición del cubo alrededor del GameObject
                    Vector3 cubePosition = position + new Vector3(x, y, z);

                    // Instanciar el cubo en la posición calculada
                    Instantiate(cubePrefab, cubePosition, Quaternion.identity);
                }
            }
        }
    }

Then with LineRenderer but only a square in the middle if lucky

private void GenerateGrid()
    {
        // Obtener la posición central del GameObject
        Vector3 center = transform.position;

        // Calcular el tamaño del cuadrado
        float halfGridSize = gridSize * 0.5f;

        // Calcular las posiciones de los vértices del cuadrado
        Vector3[] squareVertices = new Vector3[]
        {
            new Vector3(center.x - halfGridSize, center.y, center.z - halfGridSize),
            new Vector3(center.x - halfGridSize, center.y, center.z + halfGridSize),
            new Vector3(center.x + halfGridSize, center.y, center.z + halfGridSize),
            new Vector3(center.x + halfGridSize, center.y, center.z - halfGridSize),
            new Vector3(center.x - halfGridSize, center.y, center.z - halfGridSize) // Repetir el primer vértice para cerrar el cuadrado
        };

        // Configurar el LineRenderer con las posiciones de los vértices
        lineRenderer.positionCount = squareVertices.Length;
        lineRenderer.SetPositions(squareVertices);
    }

Its my first time using this stuff anyway

[vernal compass]

Hey, it's my first time using BoxCast and I'm trying to make a simple ground detection for my character, for some reason the BoxCast it is only returning true for 1 frame when the character hits the ground instead of always being true

I'm not sure if it this is how it works or if I'm doing something wrong

    {

sphere/box/capsule casts ignore any colliders they start in

[vernal compass]

I see so if I cast it inside the ground collider it won't return true
Any way to work around that?

[heady iris]

You can combo it with an overlap box query.

I do that in one of my games. The big monster enemy needs to know when the ceiling is too low to stand upright

so I do a combination sphere cast and overlap to get the amount of headroom

[vernal compass]

Never heard of overlap box query, how exactly does it work?

[heady iris]

You ask for every collider that overlaps with a box.

you can also just ask if anything overlaps a box at all

So you can share some of the parameters with the box cast

A box overlap might actually make more sense here

(so, you would discard the boxcast)

[vernal compass]

I see, I'll try it! Thank you!

Hello, i have problem with netcode for gameobject. When i try to move a cube like in this code for exmeple on Host the cube scale stay on basic scale but on client the cube turn on scale *2. on my cube there is network object and network transform so i dont understand.

using Microsoft.Cci;
using System.Collections;
using System.Collections.Generic;
using Unity.Netcode;
using UnityEngine;

public class Reveal : NetworkBehaviour
{

    public Transform boule;
    public bool hasMoved;
    private Vector3 startPosition;
    private Vector3 endPosition;
    private float speed = 3f;
    private float journeyLength;

    void Start()
    {

        hasMoved = true;
        startPosition = transform.position;
        endPosition = startPosition + new Vector3(0f, 0f, 0.4f);
        //journeyLength = Vector3.Distance(startPosition, endPosition);
    }

    void Update()
    {
        float distCube = Vector3.Distance(transform.position, boule.position);

        if (Input.GetKeyDown(KeyCode.E))
        {
            StartCoroutine(MoveCube());
            BouleRougeServerRpc();
        }
    }

    [ServerRpc(RequireOwnership = false)]
    void BouleRougeServerRpc()
    {
        BouleRougeConfirmClientRpc();
    }

    [ClientRpc]
    void BouleRougeConfirmClientRpc()
    {
        StartCoroutine(MoveCube());
    }


    IEnumerator MoveCube()
    {
        hasMoved = false;

        float elapsedTime = 0f;

        while (elapsedTime < speed)
        {
            float fracJourney = elapsedTime / speed;
            transform.position = Vector3.Lerp(startPosition, endPosition, fracJourney);
            elapsedTime += Time.deltaTime;
            yield return null;
        }

        transform.position = endPosition;
    }
}```

Hello there, I have been reading a bit about abstraction, and right now I can´t figure out which scenarios are suitable for each type of asbtraction, so lets say, when should I use interfaces over inheritance and when should I use abstract classes over the 2 abstraction methods I mentioned? Any help is appreciated!
What are the specific use cases for them?

[honest edge]

Do you mean factory pattern?

if you haven't already, the best place for everything patterns realation is refactoring guru: https://refactoring.guru/design-patterns/abstract-factory

and for unity specifics, I like Jason's videos

https://www.youtube.com/watch?v=FGVkio4bnPQ&t=736s

[glossy basin]

I am fairly new to design patterns but form what I understand, this is pretty much what I described

[honest edge]

these two sources will get you probably 80-90% of the way

[glossy basin]

Ohhhh, okay, I will take a look into it!

[glossy basin]

Great, thanks you so much!

[honest edge]

This is great to start thinking in pattern right at the start of a project to avoid being stuck to old code that doesn't fit and refactor a lot

[glossy basin]

Yup, I´m learning this wayy too late, but I have an old code I want to use this pattern into

As some scripts I have are pretty much clones

So I have a player health script and then an AI health script which is the exact same thing but with extra stuff

[honest edge]

not all patterns are applicable to unity or gaming in general, but here's another source for more gaming focused pattern design

[glossy basin]

Got it, I will check which pattern suits best my use case

[honest edge]

if you get through all videos from Jason, you'll find the right fit I'm sure. Factory and Command patterns are the most common imo

https://gameprogrammingpatterns.com/contents.html

more game design focused

[glossy basin]

Very useful info, thank you very much!

[honest edge]

to your specific case, maybe start here: https://www.youtube.com/watch?v=ll6bxQGkyCk

I'm pretty sure that's what you're looking for

[glossy basin]

Seems like it, yeah, thanks!

[idle oxide]

How can I get data from a collided object. for example if I collide with an object it gets it's damage value (stored in an int) and saves it in some variable?

[potent sleet]

the Collider / Collision paramater in the Collision/Trigger method

[idle oxide]

yeah I did that but I can't seem to find a way to get the variable out

[potent sleet]

eg

void OnCollisionEnter(Collision collision)
    {
if(collision.collider.TryGetComponent(out MyHealthScript healthScript)){
healthScript.Damage(10)
      ```

[heady iris]

who owns the cube, and who is modifying the cube?

[potent sleet]

TryGetComponent
will attempt to get the Component(Script)
then put it in a variable you can use eg "healthScript"
then get your access that way.
variable should be public
but good practice is to make methods instead of directly changing vars imo
@idle oxide

[idle oxide]

This worked thanks!

[verbal shadow]

In both cases if it belongs to the client if it is he who modifies it or vice versa when he is modifying the client always finds himself with a cube of a scale multiplied by 2

[mental sigil]

I am playing around with a small "tycoon style" 2D game in unity, where the player can place buildings that do things, thats the main idea, now I am not sure how to do this, I dont want to have everything on a grid so I want to be able to freely place the buildings, initially I just had a GameManager and a List of IBuildings that keep track of all the buildings that have been place but that seems just goofy, they should just be in the game and work without needing to be stored in a list

[potent sleet]

so what is the actual question ?

[mental sigil]

How do I keep track of my buildings without having them in a list?

I wnat to collision check when placing buildings for example

[potent sleet]

use colliders

raycasts

• boxcasts

[mental sigil]

Okaaaay, I have colliders on the buildign prefab

[heady iris]

I don't see a problem with having a list of buildings.

[potent sleet]

also yeah ^

is good for you to keep track of your buildings spawned or to be spawned etc..

[mental sigil]

Well sure the list itself is not bad maybe, but iterating all my building to check collisions seems stupid since there is already a collison system

[potent sleet]

yeah def don't do that

you'd have to keep track all bounds and rotations

it makes no logistical sense if you did that

[heady iris]

indeed

[mental sigil]

And also in that case, my buildings are GameObjects obviously but they also have the IBuilding interface that seems a bad pattern to me comign from C++ where I store IBuildings that are also GameObjects which is not visible

[potent sleet]

using interface is a good way to look for Building through collider raycast hit

if(hit.collider.TryGetComponent(out IBuilding building))

though to check if things are "blocked" use a the other Physics functions

the bulk sized ones

and not rays

use rays mostly to find a spot on grid from camera pointer ig if its not a controller based

[mental sigil]

But with the IBuilings, I have the problem that if I store them az IBuildings then I could just add a new building into the list but they should all have game objects too

This feels goofy

[heady iris]

if a building is always on a GameObject, then make an abstract class that derives from MonoBehaviour

[potent sleet]

you probably want ScriptableObjects to hold specific data for each building type

[heady iris]

that too: they can contain read-only information about buildings

[mental sigil]

Ah wasnt sure I could just inherit monobehav with an abstract class

so abstracty class not interface and I can make it always a game object

[potent sleet]

if its monobehavior it has all the access to gameObject is on

[heady iris]

this would not be a GameObject

it would, however, always be attached to a GameObject

[cunning pivot]

Hello how to deal with fps arm and gun not rotating vertically just horizontally, the gun has a parent called Weapon holder that is a child of the right hand of the player, also the player is animated

[mental sigil]

Makes sense yeah okay thanks, I will do that, it makes more snese with that in my head

Thanks

[potent sleet]

uh show what you mean, rotations are tricky by description only

[idle oxide]

How could I do this using Triggers so I don't fully collide with the object because I don't like that it stops velocity?

[cunning pivot]

        _targetDirection = _playerInput.Player.Move.ReadValue<Vector2>().normalized;
        Vector2 _targetMouseDelta = new Vector2(_mouseLook.x, _mouseLook.y);
        _currentMouseDelta = Vector2.SmoothDamp(_currentMouseDelta, _targetMouseDelta, ref _currentMouseDeltaVelocity, _mouseSmoothTime);
        _xRotation -= _currentMouseDelta.y * _sensitivityX;
        _xRotation = Mathf.Clamp(_xRotation, -75, 75);
        _mainCamera.localEulerAngles = Vector3.right * _xRotation;
        transform.Rotate(Vector3.up * _currentMouseDelta.x * _sensitivityY);

[potent sleet]

make collider trigger and use this instead
https://docs.unity3d.com/ScriptReference/Collider.OnTriggerEnter.html

[heady iris]

or use kinematic rigidbodies, so that they aren't affected by physics.

[heady iris]

of course, in that case, you'll need to control the movement yourself

[potent sleet]

ok this helps, but do you have a video or screenshot I meant

[cunning pivot]

1 sec

if i parent the gun holder to the camera then the weapon rotates vertically with the camera but that leaves the hand and also the gun wouldn't position and rotate correctly with the hand

how do games handle that

[glossy basin]

Hello there, I am struggling to understand the implementation of this event, I want to subscribe to an event from my player health controller to my game manager script and then call a function inside of the event manager once this event is triggered.

So this is how I am defining my event

public class GameManager : MonoBehaviour
{
    public event Action OnHealthDamage;

 public void NotifyHealthDamage ()
    {
        Debug.Log("damage dealt");
        hitCrosshairAlpha = 1;
        inQueue += 1;
    }
}

And on my health controller I subscribe to that event, but my question is, how do I trigger NotifyHealthDamage once that event happens?

[potent sleet]

make it MP4 cause m4v not working on discord

[cunning pivot]

shoot

[potent sleet]

OnHealthDamage?.Invoke()

[glossy basin]

In my case I made a GameObject that contains the mouse look script (camera) and inside of it I placed the weapon manager that contains all of the weapon models

[glossy basin]

I tried doing this from the player health, but it gives me this error

[vivid remnant]

Hello!

So I have a weapon system that I want to improve but I'm not sure how to go about it in a way that would also keep the code clean.

I have a base class called "Weapon" in which I keep all the common properties and behaviors of a weapon and two other classes that inherit from it: WeaponHitScan and WeaponProjectile. WeaponHitScan uses raycasts in order to simulate bullets being fired and WeaponProjectile instantiates physical projectiles that detect collisions.

My problem is with regards to the way this weapons can fire. I want both hit scan weapons as well as projectile based weapons to be able to fire one shot at a time(suited for revolvers, pistols, rifles, machine guns, etc.) or multiple projectiles at once(suited to shotguns).

I know how to implement the methods that can simulate accuracy and spread but I'm not sure where should I place them in order to make sure I can create hit scan weapons and projectile based weapons that can fire in any of these two ways.

Any advice would be appreciated. Also, please let me know if you need more details. :)))

[cunning pivot]

ok but how do you manage to make the animated arms of the player move vertically with the camera too

[glossy basin]

I used Inverse Kinematics for this purpose

[potent sleet]

I think you can only Invoke an event from the class declaring

[potent sleet]

you can call the method that invokes it though if its public

[cunning pivot]

so the arms follow the gun

[potent sleet]

I'm not 100% on that just verify that

[glossy basin]

But I dont understand, what would be the point of using events if I can just call the method on the game manager to do what I need?

I could simply do manager.NotifyDamage() with no events, right?

[mental sigil]

I have added this to my building script to check if it is colliding (via its interface)
But I get two things, first, it is always colliding and second I get this error in the console, if I remove the event functions it goes away

[potent sleet]

thats why you SUBSCRIBE from another class

you dont invoke from another class

[glossy basin]

Well, I am doing this from the other class

manager.OnHealthDamage += takeDamage;

[potent sleet]

usually in OnEnable or Start

yes

but when are you subscribing

[glossy basin]

But now, inside the manager script, how can I trigger a function / bind a function to that event

Ahhh wait

[potent sleet]

manager.OnHealthDamage += takeDamage;

thats what this does

[glossy basin]

Invoke should work

[potent sleet]

wdym takeDamage gets called every time you Invoke OnHealthDamage

[glossy basin]

Nvm, I dont get it

[potent sleet]

it's very simple

like Youtube, you subscribe to a channel you want notifications from

+= subscribe to event

[glossy basin]

But that would bind a function from the player health class

What Im looking for is subscribing to an event, and performing the logic on the game manager script, not the health script

[potent sleet]

huh?

NotifyHealthDamage () is already doing that

put a method call in there?

i don't understand

what is your use case exactly cause is not making sense to me what ur doing

no reason to sub to your own event.

unless ur a child class or something

[glossy basin]

I am probably missunderstanding how events work, I will show pictures to better represent what I want to do

So this is inside my game manager class, this is the function I want to be performed once that event is triggered

and from the health class, I want to subscribe to that game manager event and trigger it whenever takeDamage happens

[glossy basin]

Yes, I added a left arm and right arm gameObjects so I can customize the arm positions there

[potent sleet]

you're doing it backwards then

[glossy basin]

So I am supposed to perform the logic from the class in player health instead?

[potent sleet]

you want TakeDamage inside of health to do NotifyHealthDamage ?

so event should fire from Health script

then manager subs to it

[glossy basin]

Exactly

Ohhhh

[potent sleet]

yeah so its backwards lol

define event/ and invoke event, inside of health script

subscribe from Manager

[glossy basin]

That makes complete sense, let me try

But considering there can be multiple players, how would I subscribe to that then?

[potent sleet]

subscribe to multple players with a loop

[glossy basin]

Ahhh, so there is no other way to that

[potent sleet]

like foreach(var healthScript in playersList)
healthScript.OnHealthDamage += HealthChangeNotify

ideally you can send the info of Who sent it as well if you add that in your Action

like Action<PlayerHealthScript> or just Player

[glossy basin]

Yup, I get your point

Thanks for your help!

[potent sleet]

[mental sigil]

I actually dont understand, I have added a rigid body and a collider to my buildings and I am listening to the OnCollisionSaty2D event to chekc if I can place a new building, (when trying to place something, I create a new GameObejct that follow the cursor position) but I never recieve the event even when I am hovering over an existing building

This code is not terribly complex with a lot to go wrong...

I know that it is not functional because if I ever once collide it will always fail

But it NVER fails as is

I started with enter/exit s but I was like maybe this is simpler for debugging

But nope, never get the event

Every building has a static rigidbody2d and a box collider2d

This is the collider and rigidbody on the prefab

[gray mural]

you have posted it 2 times on #💻┃code-beginner already

have you realised that this is a complicated issue?

[hasty haven]

Seems like a prety dumb/generic c# question but how would you all do this, use regex maybe?
I have some text blocks like "Press [Keybind] to do something" where I want to replace text within the square brackets with some other strings.
How would you all go about isolating/replacing bracket contents, even in cases where you have "][" or other potential invalid bracket pairs.

Feels like a simple interview question lol

[heady iris]

well, there's stuff like string interpolation and composite formatting

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

[gray mural]

give us an example, maybe?

[hasty haven]

Sure, a lot of these messages are in the game on inspectables.
I already have the string values looked up from user settings.
I just want to replace the inner text

[gray mural]

like:

bla,bla,bla => bla bla bla
a:b:c => a..b..c

[hasty haven]

Sure just a sec

Input text example string
inputText = "Press [VoiceProx] to use proximity chat" where VoiceProx is a key that i use to get an actual button name from in settings
That comes from InputHandler.TryGetKeycode(string keybindName, out Keycode actualButtonCode)
I want to replace the bracket contents with whatever string contents it has

private string GetFormattedText(string inputText) {
    if(inputText.Contains('[') && inputText.Contains(']')) {
        //=> Replace keybinds with mapped button names
        
        return formattedText;
    }
      else return inputText;
  }

The first block is true even if theres '][' which I dont like

[gray mural]

I still don't get it

example?

what should this return?

GetFormattedText("Press [VoiceProx] to use proximity chat");

[hasty haven]

the output would be "Press [V] to use proximity chat" where input would be "Press [VoiceProx] to use proximity chat"

[gray mural]

why is V VoiceProx ?

[hasty haven]

VoiceProx is a key that I use to say "Hey inputHandler, what button does the user use for VoiceProx?"

PlayerSprint could be a code, inputhandler returns "LeftShift"

[mossy snow]

why check for the brackets at all? Just go through your entire list of mappings and text replace

[gray mural]

it shoulg be done with Regex

[hasty haven]

I suppose that would work

[gray mural]

I gon't get it anyways.

[mossy snow]

but why? You're doing a straight replace, regex is like using a golden hammer when a simple rock would do

[gray mural]

what?
they probably need to do Regex.Replace()

[hasty haven]

So theres only 13 keybinds so the sample size is relatively small

this is only being called once when a message is loaded

Cant change binds while reading message

[mossy snow]

buddy, if he has the text "blah blah [REPLACE] blah" and he wants [REPLACE] to be something else, regex is a mega complicated solution when Replace will do

1. take your input string
2. loop over every possible mapping, and replace entries in the input string with the output mapping
3. done

[gray mural]

it's not complicated

[hasty haven]

That should probably work,
I dont believe any of the text could get replaced since the button codes are unique

[mossy snow]

exactly

[buoyant crane]

$"Press [{GetKey("VoiceProx")}] to use proximity chat";

Could you use string interpolation for this?

[hasty haven]

I could maybe append a symbol in front like $ for inline string arguments

replace $ + code

[gray mural]

private string GetFormattedText(string inputText) 
{
    string replacePattern = "[replaced]";

    string replacedText = Regex.Replace(inputText, @"\[.*?\]", replacePattern);

    return replacedText;
}

[hasty haven]

Id like to use that but these strings are defined in the inspector using a tool i made for non-programmer teammates

[gray mural]

I cannot help you more, because I do not understand what you are trying to achieve

[mossy snow]

What do you think would happen for a string like "Press [LEFT] to move left and [RIGHT] to move right"?

[gray mural]

"Press [replaced] to move left and [replaced] to move right"

what's wrong?

[wind palm]

(?'replace'\[(?'key'[\w]*)\])

You then can match the Regex, use the group "key" for your dictionary etc and then replace the whole of the replace group

[sharp oak]

Hello! I assume this is a coding issue but I could be wrong. I coded a movement system for my 2D game. I made a map but whenever I press S to move my character, he just goes through the floor rather than walking "on it". What could the issue be?

[gray mural]

you probably move it with it's transform

can you show code?

[sharp oak]

Sure, I also used the Unity Input Actions movement package too.

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

public class PlayerMovement : MonoBehaviour

private Rigidbody2D rb;

do both your character and the floor have non-trigger colliders? @sharp oak

[sharp oak]

Yes

[gray mural]

can you show them in Inspector?

[sharp oak]

Unless the difference is the issue. The floor has a Box Collider and the character has a Box Colldier 2D.

Also, yes, let me do that.

[hasty haven]

Okay I basically went with @mossy snow solution

private string GetFormattedText(string inputText) {
    // Format text only if potential bracket pairs detected
    if(inputText.Contains('[') && inputText.Contains(']')) {
        string formattedText = inputText;
        // Replace any key codes contained within square brackets
        foreach(string keybindName in System.Enum.GetNames(typeof(KeybindMnk))) {
            formattedText = formattedText.Replace("["+keybindName+"]", 
                                                  "["+InputHandler.GetKeyCode(System.Enum.Parse<KeybindMnk>(keybindName)).ToString()+"]");
        }
        return formattedText;
    }
    else return inputText;
}

InputHandler.GetKeyCode(KeybindMnk keybind) is where the true button name comes from
I included brackets in the replace.

Not the most elegant solution but it seems to work

Its not called rapidly and the input size is never huge

[gray mural]

I wonder if that's the issue.

[gray mural]

that's not the most elegant, that's the least elegant solution

[gray mural]

what if you make'em both 2D (that's 2D game, right?)

[sharp oak]

Well, I made the map 3D but am trying to play it 2D.

Which probably wasn't too smart lol

[mossy snow]

you still those unnecessary bracket checks, and made it harder to read

private string GetFormattedText(string inputText) {
    foreach (var binding in Enum.GetNames(typeof(KeybindMnk)).Select(kb => $"[{kb}]")) {

[gray mural]

yeah, it probably wasn't

[sharp oak]

I had watched a video and in the video the person had said that you could make me the map 3D but still make the game 2D

Is there any way for me to change the map to 2D without having to rebuild the entire thing?

[hasty haven]

If I understand this correctly, it would also replace keycodes that match but are outside of brackets?

[buoyant crane]

you can, you just have to be careful. 2d colliders use the 2d physics system. 3d colliders use the 3d physics system. Both aren’t compatible with each other since they each have their own implementations

[mossy snow]

no, because brackets are added around each keybind

[buoyant crane]

You can keep everything with 3d colliders. Or keep everything with 2d colliders

if you want them to interact with each other, they have to use the same type

[sharp oak]

But if I use 2D colliders on the 3D floor, I can't change it on the Z Axis, which means it won't cover the entire floor?

[hasty haven]

Thanks @mossy snow, you're getting a promotion

[buoyant crane]

can you show a screenshot of your scene? it’s a bit difficult for me to visualize the issue you are having. You’ll have to have a 3d collider if you want it to interact with a 3d floor

[sharp oak]

I have a 3D map with a 2D character. And whenever I go into the camera and press play, he will go straight through the floor.

[buoyant crane]

give him a 3d collider

[sharp oak]

In the component section is it called 3D collider or Box Collider?

[buoyant crane]

box collider

[buoyant crane]

they’ll also need a 3d rigidbody instead of the 2d rb

which should just be called Rigidbody

[dusk apex]

If you're working in 3d, the physics components need to be non 2d.

[tropic quartz]

Worth noting that if you have bumps on the ground, a box collider can easily get stopped by them because it's not rounded at the bottom, so it won't slide over them easily.
But in a flat game a box is super efficient for sure.

[sharp oak]

Well in doing of that, my character fell straight through the floor and now I have a ton of errors. Since my movement code was set to RG2

[buoyant crane]

does the floor have a collider as well that’s 3d?

[buoyant crane]

You’ll have to update your code to reflect your change

[sharp oak]

Yes

[buoyant crane]

show the inspector of the floor and the player

[sharp oak]

First one is the floor and second one is the player.

[buoyant crane]

disable the script for a sec, and see if it still falls through

[sharp oak]

I cannot play unless I fix the errors.

I do apologize to you guys, I don't have much knowledge have this stuff.

[somber nacelle]

You probably need to reassign the rb variable of the 'PlayerMovement' script in the inspector

[sharp oak]

That's what I thought, but that option is greyed out

[buoyant crane]

I would probably just disable the script for now. Is the object falling through the ground still?

[somber nacelle]

wdym it's greyed out? 🤔

[sharp oak]

Normally you would put Rigidbody2D in the script then drag the Rigidbody2D into the settings of the script in the Inspector. But since I don't have a Rigidbody2D, I don't know what the line of code is for the 3d version. And same with the Vector. It used to be Vector2 but that isn't working anymore.

[sharp oak]

I cannot tell. I can't press play to see if it falls through because I have all of the errors

[somber nacelle]

can you show your code and what the inspector for the object looks like?

also the 3d rigidbody is literally just Rigidbody which you can clearly see in your previous screenshot that shows a rigidbody component and also has a convenient (?) button that takes you to the docs for it

[sharp oak]

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

public class PlayerMovement : MonoBehaviour
{
   private Vector2 movement;
   private Rigidbody2D rb;

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


   private void OnMovement (InputValue value) {
        movement = value.Get<Vector2>();
   }

   private void FixedUpdate() {
        rb.MovePosition(rb.position + movement * Time.fixedDeltaTime);
   }
}

[somber nacelle]

well they are private so of course they won't appear in the inspector unless you serialize them using the SerializeField attribute

but also this object clearly does not have a Rigidbody2D on it so that is why you were getting the errors

[sharp oak]

Exactly, but whenever I change Rigidbody2D to just Rigidbody, I still get errors.

One of the errors says something about Vector2 being wrong.

[somber nacelle]

well yes, MovePosition expects a Vector3 not a Vector2. you will need to create a Vector3 from the movement vector so you can put the Y axis into the Z axis

Yea, I will check this out and see if I can learn anything. Thank you guys for the assistance though

Besides that, unless the guide covers it, is there a way to completely change my map to 2D, or is the only way to do that to rebuild it?

@glossy basin @potent sleet sorry to disturb you but just wanted to say thank you for the guidance, the solution was IK now even when i turn the camera up it works nice

Glad you got it working

Hello there, I guess this is kind of a beginner question, but how can I use a coroutine on a class that derives from an abstract class of type ScriptableObject?

public class ChargeWeaponPreset : WeaponBase

I have this class, where I want to use something like StartCorotine(Coroutine()); but since the base class is of type Scriptable Object, I cant do that

This is my base class

public abstract class WeaponBase : ScriptableObject

[wind palm]

A global coroutine manager may work? If you're using a singleton pattern to access it, it should be relatively straightforward.

[glossy basin]

I thought of that, but I cant think of how I could be calling StartCoroutine from inside the ChargeWeapon class

How can I let my manager know that it has to start that coroutine

[buoyant crane]

you need a monobehavior to start the coroutine off the SO

[wind palm]

So if you have a class that has a public static instance of MyClass that extends Monobehaviour, you'd just do MyClass.Instance.StartCoroutine

Then any SO can use the same GO

[glossy basin]

I guess I could use my weapon manager class to do that

[wind palm]

If there's any chance you may need it for any other areas, it'll be better to separate it

Otherwise (as an example) your armour would need a separate one that's exactly the same, or call on your weapon manager for it.

Which makes no sense

[honest edge]

sound like a great place for the command pattern here. leave the command base class handle the coroutine and just use them from anywhere.

[glossy basin]

Yup, I get your point

[glossy basin]

Interesting, I will take a look into that

[honest edge]

check the one from Jason like the one I sent earlier today. You'll see how you can apply this specific case to it

and unbound these things from the code itself but just creating instance of the command and executing them. The execution is then handled outside of the class you want to call it from (Thecoroutine in this case) and run in your commands instead.

[wind palm]

Sounds very over engineering for needing to call one method on a Monobehaviour xD

[languid hound]

Is there anywhere I can learn how to get the stack trace from a crash dump file?

[honest edge]

that's always up to the use case. we have no context on how reusable this needs to be here. could be

[vagrant pelican]

isnt there anyone to help me with creating a 3d steering wheel controller pls

[woven crystal]

Hello. I've got some issues with my character movement.

Currently using a fixed upate to move my character.
I have an issue where my character suddently stops moving then sort of teleports forward with a jittery movement.

You can see in the video from 0:03 - 0:04 seconds the player stops briefly then appears to teleport a bit in a jittery movement.

I've tried to enable interpolate but doesnt seem to fix the issues.
Help would be appreciated!

Here is my code and the video to show it.

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

public class IsometricPlayerMovementController : MonoBehaviour
{

    public float movementSpeed = 1f;
    public LayerMask solidObjectsLayer;
    public LayerMask interactableLayer;
    IsometricCharacterRenderer isoRenderer;
    //private PlayerInput playerInput;
    private PlayerInputActions playerInputActions;

    private Rigidbody2D rbody;

    private void Awake()
    {
        rbody = GetComponent<Rigidbody2D>();
        isoRenderer = GetComponentInChildren<IsometricCharacterRenderer>();
        //playerInput = GetComponent<PlayerInput>();
        playerInputActions = new PlayerInputActions();
        playerInputActions.Player_World.Enable();
    }


    // Update is called once per frame
    void FixedUpdate()
    {
        Vector2 currentPos = rbody.position;

        Vector2 inputVector = playerInputActions.Player_World.Movement.ReadValue<Vector2>();
        inputVector.y = inputVector.y/2;
        /*
        float horizontalInput = Input.GetAxis("Horizontal");
        float verticalInput = Input.GetAxis("Vertical");
        //fixes diagonal movement on isometric scene 
        if(horizontalInput != 0 && verticalInput != 0)
        {
            verticalInput = verticalInput/2;
        }
        Vector2 inputVector = new Vector2(horizontalInput, verticalInput);
        */
        inputVector = Vector2.ClampMagnitude(inputVector, 1);
        Vector2 movement = inputVector * movementSpeed;
        Vector2 newPos = currentPos + movement * Time.fixedDeltaTime;
        isoRenderer.SetDirection(movement);
    
        rbody.MovePosition(newPos);

    }

[knotty sun]

you really should not be doing this

float horizontalInput = Input.GetAxis("Horizontal");
        float verticalInput = Input.GetAxis("Vertical");

in FixedUpdate

[woven crystal]

would this go in update?

[knotty sun]

yes and cache the values for use in FixedUpdate

[woven crystal]

Well I hope that fixes the issue im having

oh wait no

thats the old unity input system

i commented that out actually

@knotty sun

[dusk apex]

The section looks commented out.

[glossy basin]

You are doing the same with the new input system there

[knotty sun]

indeed, sorry I missed that, same applies for new input system though

[woven crystal]

So what specificlaly should i replace and put in update?

Vector2 inputVector = playerInputActions.Player_World.Movement.ReadValue<Vector2>();
inputVector.y = inputVector.y/2;
inputVector = Vector2.ClampMagnitude(inputVector, 1);
Vector2 movement = inputVector * movementSpeed;
Vector2 newPos = currentPos + movement * Time.fixedDeltaTime;

this entire part?

[dusk apex]

The hiccup honestly looks like low frame rates where a teleport occurred due to fixed update occurring more than once.

[glossy basin]

Vector2 inputVector, cache this globally, set the value in Update

and use it in FixedUpdate

[dusk apex]

Projected path and position looks correct.

[woven crystal]

how would i fix that?

its honestly getting annoying cuase it def occurs more than once

[dusk apex]

Not sure what there is to fix. Profile your application and see if it's really a delay there.

[woven crystal]

There is

I ran the build and the issue still persists

[honest edge]

fixedupdate can occur 0 to many times per frame. Usually use for physics based stuff. Any input might not be read here.

[woven crystal]

I had thought it would be an editor issue so I ran several builds

But still has this issue

[dusk apex]

I think the teleporting is the concern here rather than input lag.

[woven crystal]

Yeah.

I just cant seem to fix that random stop and then teleporting foward outta nowhere

[honest edge]

it might still be linked. Does it teleport without any inputs?

[woven crystal]

it would be okay if it happens once, but it happens like once every 10 seconds? sometimes more

[wind palm]

It should not be more than 50 times per second unless you change the settings.

[wind palm]

That sounds like garbage collection, but without playing with your project I couldn't say for certain

[woven crystal]

I'd be more than happy to compile my project and send a zip file

for you to play around

@wind palm

This things been driving me nuts as I've been trying to fix a lotof things

[wind palm]

Yeah, I don't run .exe files from discord

[woven crystal]

Turning interlpolate on and off/ messing with the physics stuff

[wind palm]

Not that I think you're up to no good.

[woven crystal]

Oh.... welp

[wind palm]

Profiling is the best way to see where the issue is.

[dusk apex]

Between 3 to 4 in the video, the character makes a slight jump. This likely occurs because draw frames were missed but physics frames still accounted for the delay (teleport). You could either not move accurately and in Update with some max distance threshold or accurately as you've got it with a teleport visually shown. This implies that there is really a frame delay. Use the profiler to ensure that's the issue.

[woven crystal]

Is there a way I can share the profiling results?

Not really sure how to read the profiling results

But I do notice that whenever the teleport issue occurs theres a spiek of some sort

[wind palm]

There are tons of guides online that'll do a better job than a text based chat

[woven crystal]

Not sure if this helps though

But it occurs at 0:01 - 0:02

[wind palm]

It looks like the garbage collector

If it's the dark green mostly

Looks like it on my phone.

You need to be careful with allocations.

[glossy basin]

Agreed, looks like GC collection

[pure dragon]

is using public dynamic Execute(){} when using the Command Pattern system bad practice if I want to return a variable to the commands caller?

[glossy basin]

I suggest you enabling deep profile and track down where the excesive GC is happening

[wind palm]

Do not use dynamic in game development

[pure dragon]

Do you know why and what to replace it with in that case? to me this just seems like the cleanest way to return data for the command pattern guidelines in particular.

[knotty sun]

since when did unity even support the dynamic keyword?

[ashen yoke]

use delegates

[mossy snow]

your command is a leaky abstraction if the caller is getting data from it, so technically a misuse here

[ashen yoke]

replace with object casts if you cant resolve types at compile time

[wind palm]

Dynamic is extremely slow. The C# compiler does not know what it is at compile time so has to figure it out as it goes. Which is clearly not good.

It's like me being you a piece of paper with random words and telling you to work it out, and you cannot do anything else until you know what it means.

[ashen yoke]

dynamic has roughly same performance as reflection

[mossy snow]

dynamic is also not supported on some platforms that don't allow code jitting, that's the main reason to avoid here

[ashen yoke]

and not "get meta once reuse later" but do it all over at every call performance

[wind palm]

I mean that too I guess, but performance is key where a single line can cause your game to reduce in frames.

[pure dragon]

i see

[wind palm]

Gives you less leg room to do other graphical "stuff".

[pure dragon]

in what way would I be using delegate by the way? like a public delegate int Execute(){} or something?

[wind palm]

It entirely depends what data you're retrieving

If you have a ICommand interface, that would be so much better.

[ashen yoke]

you can use out params, you can use closure

but yeah type system is better

[pure dragon]

isnt the command pattern design all about the paramaters of the Execute method being empty though? and even if you would isnt it impossible to store a refrence as a class variable?

[pure dragon]

and yes I am using an ICommand interface, which all commands derive from

[ashen yoke]

object b = new object();
Action a = () => {
  int i = 5;
  object obj = b;
  print(obj);
}

is this a command?

[pure dragon]

but that would pass by reference not by value right?

[ashen yoke]

only structs are passed by value

class Command<T>
{
    private Func<T> del;
    public Command(Func<T> del)
    {
        this.del = del;
     }

     public T Execute() => del?.Invoke();
}

Command<int> icmd = new Command<int>( () => 
{
    MySystem ms = GetSystem<MySystem>();
    float time = Time.time; 
    ms.PrintTimeBetweenCommandCreationAndExecution(time, Time.time);
});

is this close to what command pattern does?

[cursive moth]

Hi, I created a simple tool for mass renaming stuff but the problem is that it adds a 1 for each selected object.
Is there a way to prevent it from running for each selected object or do I have to write a different piece of code?

using UnityEditor;
using UnityEngine;

namespace Assets.NNR.Editor
{
    public class MultiObjectRename
    {
        [MenuItem("GameObject/Rename Selected Objects", false, 0)]
        private static void RenameSelectedObjects()
        {
            int objectCount = Selection.objects.Length;
            if (objectCount < 2)
                return;

            Undo.RecordObjects(Selection.objects, "Multi Object Rename");

            for (int i = 1; i < objectCount; i++)
            {
                GameObject selectedObject = Selection.objects[i] as GameObject;
                if (selectedObject == null) continue;
                selectedObject.name = Selection.objects[0].name + " " + (i + 1);
            }
            Selection.objects[0].name += " 1";
        }
    }
}

What would also be nice is opening up a dialog where you could enter a name but I wasn't able to figure out how to do that :/

[cursive moth]

forgot to send a picture of the result

[dusk apex]

Keep a copy of the original name and add the value to the end.

[pure dragon]

dont really know what you are asking of me here but I suppose it would be? although this does seem a bit hacky.

[cursive moth]

what's the point of storing the original name if I am not changing it till the very last line of the code?
for loop starts from 1, not 0

[dusk apex]

Assuming the name of the object selected is simply concatenating numbers to itself

[cursive moth]

purpose of this tool is mass renaming objects, it should look like this:

Plant Slot 1
Plant Slot 2
Plant Slot 3

etc.

[ashen yoke]

you tried using dynamic, closure may be hackier than hundreds of command classes manually typed out, but its flexible

and you can use some factory if you need reusable commands

or you can mix the two, and have a generic command with a closure in it

[pure dragon]

I suppose will consider that then, although I dont imagine it being that clean in my specific use case as many enemies will be using the same command/action most likely. thanks for the help though I will definitely look into that.

[woven crystal]

I sent a copy of the build to my partner

He has no issue walking for 10minutes

He also had his profiler on and we didnt see any spikes

[dusk apex]

You haven't explained what's going on (can be determined by logging) but I'm assuming the function is occurring x times for every object selected, the last line adds 1 x amount of times. Then you've got one final rename that adds the index to the end.

[wind palm]

It's highly dependent on pc specs etc.

Your issue is GC though.

You need to look into it.

[dusk apex]

Where the final name is that of the object at index 0 with an extra index numeric that you're concatenating.

[leaden ice]

Just save the original unnumbered name in a variable instead of reading it from the first object

[woven crystal]

Well technically if the issue is GC, wouldnt he also have the same problem?

He walked around for 10min and we couldnt find any issue

GC wouldnt just happen jsut to my pc right?

[cursive moth]

I did explain what happens.
For each selected object there is an extra 1 added before the final index because the function runs for each selected object.
I am asking if it's possible to run this function only once no matter how many selected objects there are.

[wind palm]

It's highly dependent on the pc. GC happens in everyone's pc. But everyone's pc handles stuff differently. If you both ran a benchmark test you'd get different results too

[cursive moth]

chat gpt did that, the issue with that approach is that you can't change the value of the first object at all(I want it to end up as Item 1 not just Item) because you'd end up with the same issue I had

[wind palm]

Perhaps theirs is just faster

[woven crystal]

Howd you suggest I fix it ? Did a lot of google searches to no avail 😭

[wind palm]

There is no just 1 answer

For instance if you're using raycasts make sure you're using the nonalloc versions.

[dusk apex]

Garbage Collection happens if you're allocating and freeing memory (no longer referencing memory). Depending on computer/device hardware, you may or may not feel the impact. It's likely there though if you're both running the same application.

[wind palm]

Arrays can be expensive too if used improperly.

[woven crystal]

No raycasts nor arrays have been usen so far

Only arrays for direcitonal facing

[wind palm]

Then you've got issues with other elements in your code

[woven crystal]

static arrays

[wind palm]

Static arrays are ok as look as you're not recreating them

[woven crystal]

Theres really only one other script that is being used to sort isometric sorting

[wind palm]

If I did new int[1024] every update it'll have an effect

[woven crystal]

Nah we arent recreating them. Theyre just used to store the directions the player will face

[cursive moth]

this is kind of a workaround but not really because it requires you to add a 1 at the end of the first selected object(Item 1 instead of Item):
https://gdl.space/nayoqozare.cs

[wind palm]

Clearly something is happening for GC to trigger

[dusk apex]

I'm on mobile and am assuming GC was kicking a fuss.

[leaden ice]

I don't understand what you mean by you can't change the first at all

You can do whatever you want

[cursive moth]

if you do change the value of the first selected object it'll just do the same thing my code did

[leaden ice]

Wrong

[cursive moth]

you'll end up with Item 1 1 1 1 1 2

[leaden ice]

Not if you actually save the unnumbered string in a variable that is unrelated to the object

And reuse it

[cursive moth]

how can I do that tho?
If I do it inside of that function it'll just get called for each object and I'll end up with the same thing that I have rn

[leaden ice]

$"Item {n}"

Pretty much all you need

[cursive moth]

ik what string interpolation is and how to use it, I don't see how that'll solve my problem

[woven crystal]

Yeah I know that too but its kinda hard to find out 😭

[dusk apex]

If the function is called for each item, you wouldn't need the for loop. Just a variable.

[woven crystal]

Any specific way to figure it out?

[leaden ice]

$"{originalName} {n}"

Without ever changing the originalName variable

[cursive moth]

and when do you store a value into the originalName?

[wind palm]

You'll have to go through your code.

[cursive moth]

if you do it inside of the Rename Objects function it'll get called for each object and you'll end up with the same thing I have rn

[cursive moth]

not sure you can access the object which it is currently being ran for, let me check

[leaden ice]

You need to keep it separate from the display name

[dusk apex]

You know why you've got a bunch of ones there right? Not a trick question. It's because the function is concatenating one a bunch of time to element 0.

[cursive moth]

yes, pretty much what I've been saying this whole time, each time the function is called it adds a 1 to the original object's name for each selected object.
I've been trying to avoid that this whole time but idk how(keep in mind I still wanna rename the first selected object by adding a 1 to the end of it's name)

[dusk apex]

That isn't the issue though. Issue is that somewhere along the line, the for or if statement actually becomes valid and concatenates the name of the first element (which had a bunch of ones) plus index to each element.

I give up.

[cursive moth]

ok, I'll comment the whole for loop and end up with the same thing

[cursive moth]

here:

it's not the for loop that's causing the issue with the said approach

[cursive moth]

I am not entirely sure what you mean by display name and keeping it separate from that

[vagrant pelican]

İ need a 3d steering wheel controller script but i dont know how to make it the AI and YouTube cant help me

Can you help me doing it

[lean sail]

before you make it AI, do you have a script that works based on your input?

[cursive moth]

please @ me if you have any other ideas

[lean sail]

what are u even trying to do, the script you posted does what its told to

[vagrant pelican]

İ can only rotate my steering wheel when i presses a key to the left and when pressed d key to the right

[cursive moth]

I am aware of that, I am asking how to edit it in a way to do something else

[lean sail]

i didnt see the original problem, its far up

[vagrant pelican]

This is all i can do but i need returning steering wheel and Max rotation angle etc

Like ETS 2 game

[cursive moth]

The first one I sent renames all the objects with additional 1s for each selected object.
I've made a workaround which does work but requires you to add the 1 to the end of the 1st object's name(I'll reply to that message).
I am asking if it's possible to run the said function only once no matter how many objects are selected or have some other workaround which doesn't require you to add a 1 to the end of the first object's name.

In case you missed it, it's an editor script which you access with the right click menu:

[lean sail]

your steering wheel should go towards its max rotation from provided input. your input should work independently from your steeling wheel. Then you can swap out the input and give whatever AI input (like the AI gives vector3.right if it wants to go right for example).

[leaden ice]

All you need is like:

for (int i < plantBar.transform.childCount) {
  plantBar.GetChild(i).name = $"Plant Slot {i}";
}``` no?

[lean sail]

honestly the way u explained this doesnt even say what goal u are trying to achieve.

doesn't require you to add a 1 to the end of the first object's name
literally nothing requires u to do this..?

[cursive moth]

I don't want it to be called item, it is a script which is supposed to work with any name you input as the name of the original object.
At first, I wanted to have a dialog that would accept a string as an input for the base name but I couldn't figure out how to do that so I settled with this.

[lean sail]

can you explain the actual goal? because everything im reading seems like im missing some massive context. Without this context, it seems like u just dont know how basic c# works or loops

[leaden ice]

There's not really a way to do this in general without trying to parse the "unnumbered" name from the first element, because it's impossible to tell if a number in the is from doing this code or just manually placed or something

if you don't add 1 to the end of the first object's name with this approach it'll end up like this:

Item
Ite2
Ite3
.

You could use a dialogue too if you want

To enter the unnumbered name

[leaden ice]

You have to be smarter about parsing the name

You can't just assume the name has a number or that the last character is a number or something

Your code would have to check

[cursive moth]

I am well aware of that, the problem is that at the very end of what you are suggesting I'd have to change that object's name to Item 1 from Item and end up with the exact same thing

[lean sail]

im probably missing too much context, this sounds like a complete beginner problem to me where u just use an if statement to check if its 1

[cursive moth]

I tried doing that but wasn't able to find proper docs for it

[leaden ice]

No? Why? All you need to do is write code to try to parse the "plain" name from the name of the first object. Once you have that it's the simple for loop

Basically that just means looking for and removing any numerical characters and whitespace from the end

[cursive moth]

sure, and if the base name is missing 1 at the end I want to add it, therefore requiring me to edit it's name and ending up with 1 1 1 1 :/

[leaden ice]

No

Again

It doesn't matter

[leaden ice]

You write the code like this

And replace the hard coded string for your parsed object name

Without the number

[leaden ice]

As long as you do this when parsing the name you're good

[honest edge]

Sounds to me like it's just a matter of parsing the thing and removing any numerical character and going from there.

[cursive moth]

what if the base name has the numeric value at the end of it's name?
Plant Type 12 for example.
