It tells you everything.

The Object you want to instantiate is null.

#

So, jobPrefab is null

#

oh I see

#

I need to make the jobprefabs but now it still gives me a null despite it being filled

#

I am still not getting where is null because I got the job prefabs

Gonna try this again. Believe me, if I could stop trying to solve this problem I would, but my company needs me to be able to use Unity.

Is there ANY WAY AT ALL to determine why 'reload script assemblies' sometimes never completes? Like a log of what it is doing, or a memory profiler for that process, or anything? I'm begging here on my hands and knees.

I have a subclass of ScriptableObject, say "MyScriptableObject", that has a single static variable called "instance" representing a singleton for the class.

In the Awake() method (called when the ScriptableObject is created via the Editor menu item), I do the following:

instance = this;

I set a breakpoint and confirm Awake() is being called and that "instance" is set.

However, when I run my app and access MyScriptableObject.instance, the value is null, as though it's never been set.

Any ideas?

Hey everyone! My code works perfectly fine when i have it in debug mode but the moment i let it run without stepping through it breaks

jolly token
livid zephyr
#

The code is supposed to get to the zones in the list and reveal them as soon as it lands on the zone and then it should be transitioning to the next one and do the same until there are no more zzones but currently its bugging out. Like it'll either reveal one and then stay there or it'll revel two and then go the the third one and stay there and not move

#

I've rebaked the nav mesh and everything

livid zephyr
#

@jolly token ?

jolly token
livid zephyr
#

the Coruotine method is the part im stepping through @jolly token

#

And yes that is correct

#

The zones are gameobjects , and i have a ground with a navmesh on it and the thing is that is was working perfectly and then i made my field bigger and then rebaked the mesh and this is when the problem started happening

jolly token
livid zephyr
#

like i just ran it now, and it was working fine and revealed two zones and then when it got to the third one, it didnt reveal it and just stood there

jolly token
#

Maybe make it into while loop (instead of WaitUntil) and log the navmesh agent values in the loop?

#

Path state and position, remainingDistance etc..

#

So you can see what is going on when not using debugger

what would be a good approach for combining root motion and in place animations ?
so far I tried using StateMachineBehavior that enable and disable applyRootMotion on the animator
it worked fine, until a case with character facing came up (some states need to rotate the game object over Y before playing the animation)
I can solve this by creating specialized StateMachineBehaviors for each state that needs something like that, but it feels like a wrong solution

#

I just started dealing with animations, so don't know the good practices

#

even the general StateMachineBehavior I mentioned also feels hacky, because I have to add it to every state

#

to give more details - I want basic locomotion to use in place animations
and things like skills and special locomotion (dash) to use root motion animations

Hopefully this is the right place to ask this.
I'm trying to instantiate objects in an arc in front of a boss. I've tried using the Boss' transform.forward, but no matter where it's facing, the objects always spawn in the same pattern, facing forward on the world's Z axis.
Not sure if the parenting is weird, but I'm using the top most parent and I've made sure that whenever it's rotating, the Y axis on that transform is moving around

Anyone know how to cap/or limit the growth of ContentSizeFitter?

#

As far as I know, you can use "Min Width/Height" in any LayoutGroup to set the minimum...

#

You then use ContentSizeFitter to let it grow based on the size of its content...

#

But then how do you cap it at a X amount?

A chat bubble that starts off as small as the text inside, but grows its width as the text increases, up to a width cap,
then it expands vertically (down) indefinitely, or even this up to a cap, after which, the text turns to ellipse.

I am trying to make movement for player based on my own simple state machine.
This player movement module supposedly works so that MovementAction-s listen to event OnActivation and OnDeactivation in State-s which can be activated and deactivated by the state machine with only one state being active at a time.
There may be such MovementAction-s as for example MoveAction and JumpAction which would be able to connect to such states as OnGroundState or InAirState. If JumpAction is connected to InAirState the action will work regardless because it doesn't care to which state it is connected.
My hierarchy for this code currently is MovementAction>StateMachine>States, so MovementAction and StateMachine provide some interfaces which are then implemented in StateMachine and States. I made the hierarchy this way because I thought the thing I needed was movement which is implemented in MovementAction so everything else must be details of implementation of MovementAction.
But now I have a feeling that I should place StateMachine on the top because there has to be a moment in time when I will activate the entire movement module and there has to be something exact activated by this action (regular word) such as an object implementing ILauncher which would be the StateMachine and in this sense the StateMachine is also controlling everything.
I am asking for clarification on what approach I should use and what's wrong and/or correct in my thoughts on this topic. From answer to this post I want to get precious experience which I would be able to use in other hierarchies.
Thank you.

Unity's built in GetComponent API fails to account for generic covariants

#

It's a niche use case, but I just stumbled upon this bug and had to write a custom GetComponent function that accounts for it

#

I'll file this as a bug

pliant crest
finite pond
#

yea sure

#

so basically, I have an IProvider<out T> interface

#

assume I use IProvider<IItem>

#

technically, you can cast this to IProvider<object>

#

I tried to use GetComponent<IProvider<object>>() to get a reference to my IProvider<IItem> implementing MonoBehaviour, but it returns null

finite pond
pliant crest
#

that doesn't look like a bug

finite pond
#

well, it should return my IProvider<IItem> when I use GetComponent<IProvider<object>>()

pliant crest
#

but that causes other issues

finite pond
#

which are

pliant crest
#

like if you actually had a type of IProvider<object>

#

and if you had many other types

#

how would it know which one to get you

finite pond
#

you can use GetComponent<MonoBehaviour> and it just returns you the first monobehaviour, not really an argument imo

#

just the nature of OOP

#

for getting specific ones, you can use the GetComponent(Type) overload

pliant crest
#

huh wait you can add the same monob onto a object?

finite pond
#

wdym

pliant crest
#

thought components were unique

finite pond
#

yea?

pliant crest
#

like you can't add two transforms

#

so how do you add the same monob

finite pond
#

what are you talkin gabout

#

all your custom components inherit from MonoBehaviour lol

pliant crest
#

yeah

#

ahh wait

#

you are saying literally passing monob as a type

finite pond
#

Well yea, in the case of that its the generic argument of the function overload

pliant crest
#

does that work for any other generics?

#

or is that some edge case

finite pond
#

The issue i brought up you mean?

#

IProvider?

pliant crest
#

na passing in monob

#

so if you had just

#

some abstract class

#

that inherited monob

#

could you do GetComponent<abstract>

finite pond
#

yea ofc that works haha

pliant crest
#

and then get one of them back

finite pond
#

dont tell me you didnt know

pliant crest
#

i don't have a use for that

#

so never had to ask that question or need to know it

finite pond
#

well, technically its C# internal functionality

#

not really unique to unity

pliant crest
#

unity does the compare does it not?

finite pond
#

I'm pretty sure the implementation is in C++, so I have no idea what it does

#

It most likely does not use C#, for example using Object is AbstractClass syntax

pliant crest
#

i don't think IProvider<object> and any IProvider<out T> is the same in this case anyway

#

with the comparison you are referring to

finite pond
#

it's not exactly the same, no, but since GetComponent accounts for inheritance, it also should account for generic covariants.

#

It's only valid for <out T>.

pliant crest
#

right

#

building il2cpp from the editor on windows always works. headless windows il2cpp does not always work. usually never on any other platform, for a clean pipeline

#

mono always builds correctly. i don't think the unity team tests building headlessly in il2cpp on anything but their idiosyncratic editor computers and their own cloud build servers

#

which have undocumented side effects

#

that occured on them a long time ago

#

for example they probably log into their windows build machines with RDP at least once, which causes all sorts of side effects

trust me

I feel like this requires an article to answer lol. For now I can say that it'd be best to try and see how it goes, and look into how other (open source) state machine / locomition implementations are. You could StateMachine and MovementAction both reference each other, that's fine too. Other people and I might be able to give better answer if you have some mini-example in code.

I think you want reusable feature for multiple state, so that is pretty close

#

If you think of Mecanim, State is just an entity, does not have characteristic.
Then maybe you can think of making OnGroundState as OnGroundBehaviour and JumpAction as JumpBehaviour, and attach them into same state. It will make the layout plain, and you don't have to think too much of what should be MovementAction and what is State.

flint geyser
#

I think it isn't what I was asking about... I had 2 approaches in my mind:

  1. StateMachine should be atop the hierarchy because there has to be a point in a program which would launch everything else and StateMachine looks like a good candidate for it.
  2. MovementAction should be atop the hierarchy because it's my intention to move the character and everything else is just implementation detail.
    And I was asking which is more correct should I say from the point of building an object oriented application with nice changeability?
undone coral

#

That being said, I would say you can reuse MovementAction across multiple StateMachine if you need, but StateMachine should still be on top of hierarchy, in a context of a state machine.

#

I dont want to hijack the discussion but I'm just curious if anyone is using com.ai.navigation (the navmeshcomponents thing) and could elucidate for me the intended method to execute NavMeshLinks manually as opposed to the old OffMeshLinks. I've already figured out how to get a reference to the NavMeshLink by casting the navMeshOwner on the agent to the right type, but I'm curious as to how I can leverage the NavMeshLink now being an area. Getting a reference to the component obviously just gives me the start and endpoint, not the path the agent is intending to take through the link's area. It's perfectly functional as is but I feel like I'm missing some of the new features by doing this. Are the intended traversal points contained within the calculated path? If so, isn't that odd since it's not necessarily obvious which points on the path are relevant to the link?

#

And before someone says - yes I've asked in the AI channel several times, it doesn't seem that anybody over there is using the new navigation package or knows how to use the new links.

#

(I am manually animating the movement between the links through code since I need the agents to do special stuff when they cross it such as walk to a door switch and play an animation to open the door prior to crossing the link)

undone coral
#

since it sounds like your issue is related to rigging, and you are correctly using navmesh links

#

you can fork the source and make whatever changes you want too

tough knoll
#

Just let him cross naturally and then reconstitute the intended animation path based on what the agent did???? That sounds gory as fuck

#

I really hope there's a better way but yeah, I guess that could work. The agent and the graphics are already seperate in my system by the way

undone coral
#

are you asking someone to read the package's source code to find "the path the agent is intending to take through the link's area"?

tough knoll
#

Noooo not at all

#

I'm wondering what the new equivalent of OffMeshLinkData is essentially

undone coral
#

that soundsl ike it would be the solution youa re looking for though

#

like for the purposes of rigging this animation

tough knoll
#

Like with the old system there was a struct that contained all the traversal information for the agent. The start pos, end pos, link type and a reference to the offmeshlink concerned

#

I'm just trying to figure out if com.ai.navigation has a thing that's similar to this at all. It seems like a really basic requirement that would be relevant to anyone seriously using the new system, so I was wondering if anyone is using it since they probably would know

undone coral
tough knoll
#

Yeah, that sounds like the thing

#

Wait, I'm not sure now looking at it

jolly token
tough knoll
#

okay

#

time to dig

undone coral
#

you can create a subclass of NavMeshLink and create a property for it

tough knoll
#

I don't think that's it

#

NavMesh.AddLink just adds a link to the navmesh. So the information contained doesn't have anything to do with the path of the actor, I think

#

I haven't tested this yet since I just found out about it but I'm guessing that the start and endpoints here just match the start and endpoints that are set in the link component

#

I'm talking about the specific start and endpoints on the area defined by the link which the agent is intending to take

undone coral
tough knoll
#

The old code it was a line, so it didn't matter. But it was contained in the OffMeshLinkData, a struct which was generated when an agent would take an offmeshlink

#

But yeah the offmeshlink just has a start and endpoint

#

NavMeshLinks on the other hand are now areas

#

I've already designed the game to use simple start and endpoints for the locations where agents leave the navmesh so it isn't really the end of the world but I feel like there's probably someone out there that's using this package that has an answer to this question

undone coral
#

and it will prob cross in the midpoint of the two edges

#

you're confident it's an area right?

flint geyser
# jolly token If you think of Mecanim, State is just an entity, does not have characteristic. ...

Well currently my states have function bool IsSuitedToBeApplied() which checks the state's condition for not forcefully entering it. For OnGroundState it would be if the player is grounded. Then when someone says to state machine I don't care what state you will be in after but not the current one - SetState(null) state machine will check the spare states' conditions and choose the first suited to be applied now as the new active one

undone coral
#

i mean i know it looks that way in the editor

#

you're confident it doesn't always cross through the "middle"?

flint geyser
#

I don't think it would easily work with what you are suggesting, would it?

tough knoll
#

:S

#

To clarify, with offmeshlinks:

  1. Wait for agent.isOnOffMeshLink to be true
  2. Read agent.currentOffMeshLinkData, which contains the start and endpoints for the crossing and a reference to the link

With navmeshlinks:

  1. Wait for agent.isOnOffMeshLink to be true
  2. Check that navMeshAgent.currentOffMeshLinkData.offMeshLink == null, which means it's a navmeshlink ಠ_ಠ
  3. Cast navMeshAgent.navMeshOwner to UnityEngine.AI.NavMeshLink, which gives you the navmeshlink it's crossing
  4. Now we only have access to the start and end points of the link, so it just crosses the middle of the link, not making use of the new feature where links are areas instead of lines
#

Jank.exe but it works, I just feel like I'm actually not doing it the right way because now my agents just still can only cross in the middle of the area

#

Maybe the area thing is just not implemented or some shit. It is under construction, I guess

jolly token
#

I'm not judging, btw. I'm saying it's not common approach, and there is usually a reason when something is not commonly used than the other. In this case the reason would be 'it's hard to control where the transition comes and goes'.

undone coral
#

it's not really an area now

#

the package is a wrapper around the familiar navmesh you've been using

#

the visualization in the link (width) is meant to show you the size of the agent that can pass

#

@tough knoll does that make sense?

#

you can prob get agent.currentOffMeshLinkData again if you want

tough knoll
#

Oh

#

Well in that case my current method works fine then yeah

#

That's kinda odd

#

Is this package a thing nobody uses or something? I understand the new features aren't incredibly useful but it's nice to be able to have individual navmeshes linked to the transforms of objects

#

also this kinda doesnt explain why area can be scaled on both axes, if it's only used to measure the width of the agent

I'm creating a 3D bullet hell game.
When creating my weapon pool, would it be beneficial to create a dictionary containing a list of each different projectile type, or is it more practical to just use one list and assign the data to the projectile as I need it?

And when using 3D models, is it appropriate to change them on demand, or should that just be reused?

# jolly token Nice, what would be your solution? 😄

My solution would be that my initial intention isn't to make MovementAction but to make player move. That can be achieved with all kinds of approaches like a state machine or a single class controlling all the player's movements. So I just will make an interface similar to IController with Enable and Disable methods. The interface will be implemented by state machine. The only question I have not thought about yet is how will be changing the states accessed by the movement actions

# jolly token Not that, I just not sure what to add while not knowing full picture of what you...

No I do not want another IController it's just that after reading Agile Software Development (only to the part with SOLID and a bit after) I think that you can create nice object oriented hierarcheis based on what is your intention. I mean, I am trying to stick to Dependency Inversion Principle (as it looks agile to me) and by placing exactly what you want at the top of your hierarchy you can similarly do the same for the rest of your program and get it done in agile fashion. Tho it is only my humble opinion and I would like you to correct it and give any insights on this topic if possible.
This my understanding is the reason why I was asking all this "what should be at the top, movement action or state machine"

jolly token
# flint geyser No I do not want another IController it's just that after reading Agile Software...

Hmm okay it gives more context. I'd have to say that you don't need more abstraction than you actually need. If you think your StateMachine will be only implementation of IController, then it's basically same thing but with additional abstraction layer. This might end up over-engineering. I'd see it practically easier to maintain if your other classes knows your state machine as state machine (maybe IStateMachine) not IController. Though I understand that you prefer using interface than actual implementation and finding an architecturally better solution.

jolly token
# mystic flume

Covariance and contravariance does not work with value types 😄

#

It will work when you change BuildTaskPayload to class,
But again in is contravariance, that will allow assigning IGameTask<IPayload> to IGameTask<BuildTaskPayload>, not the other way like you want.

undone coral
#

this looks okay, but what is your objective? @mystic flume

#

hmm based on what i am reading you should not have use generic templated interfaces

you can use IGameTask but not IGameTask<T>

using

If you have a reference to the prefab then it is the prefab in the project folder, it just doesn't save the changes to it normally. But this is more of a #↕️┃editor-extensions question.

This function is called when the ScriptableObject script is started.
Awake is called as the ScriptableObject script starts. This happens as the game is launched and is similar to MonoBehavior.Awake.

Does anyone know if it possible to set a setter for attributes? I am making a multiplayer tool and I have an attribute called syncvar. Variables with this attribute automatically get synced through the network. I want variables with this attribute only to be set by the server (there is a static bool which can be used to check if you are the server) or a client if it receives the data from the server. Otherwise I want to return an error if you want to set the variable. Is this possible, or should I just make it clear in the documentation of the tool that clients shouldnt set this variable

Well it's just the general mutliplayer logic what I'm writing. Sending data between server and clients. I have all the logic working, also for the syncvars. If you change the var on the server it gets synced for all clients.

Could someone explain why / how variables outside of a lambda expression remain in scope?

for (int i = 0; i < _inputNumberEventTriggers.Count; i++)
{
    EventTrigger eventTriggerComponent = _inputNumberEventTriggers[i];
    _mouseDownActions.Add(new UnityAction<BaseEventData>((BaseEventData) =>
    {
        GameObject elementGameObject = eventTriggerComponent.gameObject;
        int number = i;
        
        _isDragging = true;
        Debug.Log($"Drag Index: {number}");
    }));

    _mouseReleaseActions.Add(new UnityAction<BaseEventData>((BaseEventData) => 
    {
        GameObject elementGameObject = eventTriggerComponent.gameObject;
        int number = i;
        
        _isDragging = false;
        Debug.Log($"Drag Index: {number}");
    }));
    
    eventTriggerComponent.triggers[0].callback.AddListener(_mouseDownActions[i]);
    eventTriggerComponent.triggers[1].callback.AddListener(_mouseReleaseActions[i]);
}

In this code I have a list of number buttons that I am adding drag listerns too, however once I play this in the game the debugs all come out with the number 9. Which would make sense if number was being set to i, but at this point i shouldn't exist.

#

I wrote the code again like this:

for (int i = 0; i < _inputNumberEventTriggers.Count; i++)
{
    EventTrigger eventTriggerComponent = _inputNumberEventTriggers[i];
    GameObject elementGameObject = eventTriggerComponent.gameObject;
    int number = i;
    
    _mouseDownActions.Add(new UnityAction<BaseEventData>((BaseEventData) =>
    {
        _isDragging = true;
        Debug.Log($"Drag Index: {number}");
    }));

    _mouseReleaseActions.Add(new UnityAction<BaseEventData>((BaseEventData) => 
    {
        _isDragging = false;
        Debug.Log($"Drag Index: {number}");
    }));
    
    eventTriggerComponent.triggers[0].callback.AddListener(_mouseDownActions[i]);
    eventTriggerComponent.triggers[1].callback.AddListener(_mouseReleaseActions[i]);
}

Which does work, but the like with my previous statement with i, how does the variable number still exist? Are they only kept in memory because of the lambdas?

#

Sorry its a bit of a strange question, but its a concept I'd like to try to get my head around.

tender light
undone coral
#

anyway, int number = i was correctly moved. all the lambdas capture a reference to int i in the first example, which isn't redeclared in every loop, it is declared once, that is why this is confusing

#

there is only 1 int i. the code really looks like this:

{
 int i = 0;
loop:
 {
  if (i < _inputNumberEventTriggers.Count) {
   EventTrigger eventTriggerComponent = _inputNumberEventTriggers[i]; ...
   ...
   eventTriggerComponent.triggers[1].callback.AddListener(_mouseReleaseActions[i]);
   i++;
   goto loop;
  }
 }
}
#

does that make sense?

#

so now it's unambiguous how it interacts with the lambda

#

that lambda rule becomes less nonsensical

#

it's confusing because of the way the iterator is declared, not because of lambda rules

undone coral
abstract hill
# undone coral it's confusing because of the way the iterator is declared, not because of lambd...

Why are lamda's considered beginner tools?
I do understand why I is the value it is when used within the functions, my confusion mainly comes from what values remain in memory. I was under the impression that objects or base types that exit a scope get dropped in memory / opened for garbage collection. Its something I never much paid mind too until now but the questions was mainly about how the language knows to keep these variables in memory rather then getting rid of them. And what other values will this have issues with.

undone coral
#

you have to use UniRx to do what you are doing

#

in the body

#

the meaty, meaningful part of your code

#

re: the GC scope

#

one perspective is referencing a variable in the lambda function ticks up its reference count

#

so even though it exits the scope of the for loop, it ticks down its references from (_inputNumberEventTriggers.Count + 1) to (_inputNumberEventTriggers.Count)

#

so it isn't going to be garbage collected

#

until the objects with the event listener fields are no longer referenced

#

because then, transitively, the lambda will not be referenced anywhere else

#

C# does not use automatic reference counting, but it's a way to see how something does or does not become eligible for garbage collection

abstract hill
#

Oh okay, I think I understand.

#

Thank you

undone coral
#

yeah in C++, which i came to after c#, i can see how you have to be acutely aware of

#

is this thing ticking up a reference or ticking down, and who owns what

#

naturally, in c#, it's all shared pointers

#

Yeah, I have had a play with C++ in the past with shared and weak pointers, but didnt think much of that was carried over for C++ (in terms of developer usage)

Hey, can someone tell me if the way of writing these lines is correct or not? I'm not seeing any value changes, but it worked with simple numbers like 1 or 2 before. First time trying to get things like Mathf to work. I'm not seeing errors, but since I started using these equations it doesnt work anymore


        movementFactor_value2 = 1 / 4007500 * Mathf.Cos(1 * (float)_mapRenderer.Center.LongitudeInDegrees) / 360;```
#

What I'm trying to write for value1 is 1 / 11132 * 2^20-ZoomLevel and for value 2 1 / 4007500 * Cos(1*Longitude) / 360

abstract hill
#

The first issue I can see is that you dividing integers, not floats. So you may just end up with the fractional part being lost.

#

1 / 11132 will equal something like 8.9 * 10^-5, as such when this is the cast back as an int this will equal 0

#

So your then are doing 0 * Mathf.Pow(2, 20...)

#

The Mathf.Pos code should work fine, you just need to make sure your working with floats

#

Simular problem with the second line of code,

MovementFactor_value2 will equal 0, since (1 / 4007500 == 0 due to them both being ints), then (0 * Cos(anything) == 0), and then 0 / 360 will equal 0

# 
movementFactor_value1 = 1f / 11132f * Mathf.Pow(2f, (20f - _mapRenderer.ZoomLevel));
movementFactor_value2 = 1f / 4007500f * Mathf.Cos(1f * (float)_mapRenderer.Center.LongitudeInDegrees) / 360f;
#

Having f after the value should solve it

lethal flicker
#

So I just convert all of them to floats?

abstract hill
#

Yeah, that should solve it, just putting f after the numbers will keep them as floats, which will then keep the values of the equations also as floats

#

Elsewise an equation between two ints will just convert it to another int

#

So you end up with loosing all your decimal values

lethal flicker
#

Hmm, maybe it's not the equation being wrong at the moment but something instead. It's still not working after I converted them to floats.

#

But it's good to know, I definitely needed the decimal values

The _Centeringstatus here is supposed to be false/true, and if it's true, it would let the timer do this LocationRefresh() here https://gdl.space/ebijijanex.cpp (code in link to shorten it)

#

It doesn't give me any errors, seems to work on my Android phone, but not on the AR glasses I'm programming for, which are Android 10. At the beginning of this script I'm requesting GPS data fetching permissions ```public void Start()
{
Panel();
EventSystem.current.SetSelectedGameObject(firstSelected);

    if (!Permission.HasUserAuthorizedPermission(Permission.FineLocation))
    {
        Permission.RequestUserPermission(Permission.FineLocation);
        Permission.RequestUserPermission(Permission.CoarseLocation);
    }
}``` here.
#

This fetching, the timer, etc. worked when I didn't have it linked to the button but kept the timer going and going immediately beginning from the start of the app. But now that I'm trying to link it to the button it suddenly doesn't work anymore, so I think there might be a mistake in the way I used the _Centeringstatus bool here. Can anyone give me insight on what the exact issue is?

#

I have two objects, A and B. When A moves up and to the left relative to its forward direction I need object B to move up and left relative to its forward direction. This needs to work no matter what angle A or B are at.

image.png
#

My problem is no matter what I try it seems like it will move in the blue direction.

thin mesa
gleaming hatch
#

I don't want it to just move forward, I want it to move to the left as well as forward. And I need the distance to be equal to how much A moved.

thin mesa
#

and again, that's not an advanced issue. and you still need to show code. also here's another hint: transform.TransformDirection exists

gleaming hatch
#

Or right and forward, or left and backwards, or up and left.

#

TransformDirection is local space, not relative to rotation.

thin mesa
#

you didn't bother reading what it does, did you?

gleaming hatch
#

I not only read it, I tried it.

thin mesa
#

you still haven't shown code either

gleaming hatch
#

Because there is no code

#

Nothing comes even close to doing what I want.

thin mesa
#

this is a code channel mate. and you also just said you tried transform.TransformDirection. how did you do that without using code?

gleaming hatch
#

It's useless code because it's not even close to the solution.

#

I can post 10 different things I tried that did nothing but that doesn't really help anyone.

# 
        target.position = positionOffset;

        target.position = target.TransformPoint(curPos - startPos);
        target.rotation = rotationOffset * Quaternion.Inverse(startRot);

        targetChild.rotation = target.rotation;
        targetChild.localRotation = curRot;

        target.rotation = targetChild.rotation;```
#

That's something I tried that didn't work.

#

It doesn't seem advanced until you actually try it. I thought it would be as simple as transformdirection too, but if there's no parent world and local are the same, it does not take facing direction into account.

thin mesa
#

literally all you need to do is get the distance and direction of movement from object A, use transform.TransformDirection on object B to change that direction to be relative to its own transform, then move it by that direction and distance

gleaming hatch
#

Try that and tell me if it works, because that's exactly what I did first and it didn't work because that's not what transform direction does.

thin mesa
#

that is precisely what TransformDirection does, it changes what would be a local space direction to world space direction. show your code to prove that you actually used it correctly

gleaming hatch
#

"Transforms direction from local space to world space." "If the transform has no parent, it is the same as Transform.position."

#

I deleted it days ago

#

If there's no parent localSpace and worldSpace are exactly the same.

thin mesa
#

and if the fucking object is rotated a local direction is not the same as a world direction

gleaming hatch
#

Local space does NOT take rotation into account.

#

It ONLY compares it to the parent's rotation. If there is no parent then it's the same as world rotation. Try it yourself if you don't believe me.

thin mesa
#

then show the fucking code you tried and prove it doesn't work. i've used TransformDirection countless times to move objects based on their own rotation by giving it a local direction

gleaming hatch
#

Did they have parents?

thin mesa
#

no

gleaming hatch
#

I'll rewrite the code, but it's a waste of time.

thin mesa
#

do it. i would love for you to actually prove me wrong

gleaming hatch
#

What's the code on that?

thin mesa
#

it's literally just using transform.TransformDirection to change that localSpaceDirection vector to be relative to the rotation of the object and adding it to the position

#

if it doesn't work for you then the issue is your implementation. feel free to ask for help with the code in #💻┃code-beginner

gleaming hatch
#

My only guess with what could be going wrong is that this is relating to trying to reposition a vuforia camera and maybe they're doing something unexpected under the hood.

#

But thank you for proving me wrong.

#

It actually makes me feel better because that's the very first thing I tried.

undone coral
#

this thread gets a big "huh?" from me

gleaming hatch
#

Well, thank you very much. My problem isn't solved but at least I have a better idea of where to look for the solution.

undone coral
#

vuforia camera is very concerning

gleaming hatch
#

I'm trying to move the vuforia camera to match the position and rotation of a physical place using OnStateUpdated.

undone coral
#

isn't the point of vuforia cameras that they follow the device position?

#

what is the idea?

gleaming hatch
#

Yes, once it matches the world position then we want it to match device position and rotation.

undone coral
#

hmm

#

but the real camera is where it is

#

you can place the unity camera wherever you want

gleaming hatch
#

So A.) Move to the position. B.) Vuforia moves it back to original position next frame. C.) Read that frame's position and rotation update and apply it to where you were in A.

undone coral
#

i see

#

well what is the even bigger picture idea here

#

you can give me the Idea of the Idea

#

because the words you are saying don't make sense

#

i mean that i believe that you know what you want

#

but that it is hard to understand what you are really trying to say

#

you can, naturally, offset the unity camera relative to the AR device position

#

but

match the position and rotation of a physical place
doesn't make sense to me. i am imagining the Eifel tower, and then, why would you want the camera to be facing the eifel tower's z+, and be positioned in world coordinates all the way in france

#

but that's what the words

match the position and rotation of a physical place
mean

#

i'm not trying to be pedantic

#

are you trying to say you want the user to explore other locations around the world?

#

in AR?

gleaming hatch
#

No it's hard to explain.

undone coral
#

is it one of those games where you pretend to be a plant

#

and you are in a video game level

#

like you are a prop and you hide

#

lol

gleaming hatch
#

Okay, imagine you're in a parking lot, and we want to align with the parking lot. We know the unity coordinates of every parking space. You put in the parking space then the vuforia camera is placed there and continues to move and work like a vuforia camera should.

undone coral
#

okay

#

wouldn't you align the parking lot, not the other way around?

#

or am i being stupid

#

the vuforia camera is wehre it is

#

i suppose you could rotate the unity camera relative to the vuforia camera, which is so easy that i'm sure you've tried that

#

but why?

#

that doesn't make any sense

#

i assume you mean "align the parking lot such that, when you START your session, you are looking from the center of this parking space and your camera is parallel to the lines" or whatever

gleaming hatch
#

We have an existing system that auto-aligns that works for certain situations. That requires everything to be positioned at the world origin, and the camera to be placed relative to it.

undone coral
#

hmm

#

and the idea of the idea is

#

to practice parking trucks?

#

to practice being a parking attendant

#

you ARE a Mazda Miata

#

and you're actually trying to run people over, in AR

#

or people jump into you!

gleaming hatch
#

I'm under NDA and can't give the actual idea, that's as close as I can come without giving it away.

undone coral
#

okay well i have hit my limit. it is really really straightforward, using parent constraints, to adjust the orientation and position of the unity camera relative to the AR position

undone coral
#

it sounds like you are a miata with googly eyes

#

trying to find juicy targets

#

to run over

#

it's so straightforward that i am definitely missing something*

#

probably something to do with how the steering of the miata affects your ability to mow down nimble costco shoppers versus your slower, easier to target cheesesteaks-and-milkshakes crowd that also inhabit parking lots

#

you can initialize a parent constraint with the miati in the "right position" once the user has at least made their AR camera level. then you will have Aligned to the Parking Lot

#

@gleaming hatch does that make sense?

#

experiment with the parent constraint

#

then you can separately scale the target pedestrians

#

edy's vehicle physics supports deformations with soft body collisions

gleaming hatch
#

I'll play with it and see if I can get it going tomorrow. Thanks for the advice.

undone coral
#

do you have any questions about the softbody physics simulations of fat parking lot pedestrians?

gleaming hatch
#

Haha

undone coral
#

or how to correctly model the consumption of a whole costco chicken and how that will affect the mass and velocity of the target

#

ugh

Hello, I'm trying to serialize a 2-dimenional array. Guess I have to convert into a serializable type. Do you guys have any suggestions which type to use or maybe even alternate solutions?

elfin tundra
calm glen
elfin tundra
#

i meant it's possible to serialize it, not that c# or unity has libraries for it already

#

but if you make it a jagged array instead (ie int[][] bla) it might work better

#

with existing libraries

calm glen
#

I'm gonna try that, thank you. Do you know of any handy library that can handle common cases like that by any chance?

elfin tundra
#

oh well i meant change it in your code

#

but if you can't do that then it shouldn't take more than a few lines to convert it yourself

calm glen
# 
int[][] bla = new int[2][];
bla[0] = new int[2];
bla[1] = new int[2];
bla[0][0] = 1;
bla[0][1] = 2;
bla[1][0] = 3;
bla[1][1] = 4;
Debug.Log(JsonUtility.ToJson(bla));

Doesn't work either unfortunately

elfin tundra
#

oh dang

#

did you read the jsonutility docs

#

check what the available options are for arrays

calm glen
elfin tundra
#

that i cannot speak to unfortunately

#

probably just doing it manually is the best practice lmao

calm glen
#

All good, I'm just gonna write a tiny converter for my cases I guess 😉

elfin tundra
#

it is common knowledge that unity's serializer is not the best

#

so you may have to do it yourself

calm glen
#

well I'm not as knowledgable when it comes to unity/csharp, hence me asking :> But thanks again for the suggestions!

where value is the Array and itemLen is the bytes size of the array contents

Using nested prefabs instead of non-prefab nested children, can reduce scene file size significantly.
I would like to know if it can affect memory ram as well or not

#

I mean use nested prefabs in the game object hierarchy as much as possible

#

For example, I have copied a game object 100 times in a scene. It has several nested children.
The scene size is around 200MB

I'm working on reimplementing my state machine class so that the 'Step' call of the state returns a generic enum. The desired behaviour is that if i return null, i continue, but if i return an enum, i change to the state which is tied to that enum

#

but im running into a strange issue with the state interface

# 
public interface iState<TKey>
{
    public abstract TKey? Step();
    public abstract void Enter();
    public abstract void Leave();
}```
#

Step returns TKey?

# 
public abstract class PlayerStateBase : iState<ePlayerState>
{
    public PlayerStateBase(PlayerStateMachine manager)
    {
        Manager = manager;
        Owner = manager.Owner;

        Movement = Owner.Movement;
        Input = Owner.Input;
        Anim = Owner.Anim;
    }

    public PlayerStateMachine Manager;

    public StateMachine<ePlayerState, iState<ePlayerState>> Machine;
    public PlayerActor Owner;
    public PlayerMovement Movement;
    public PlayerActorInput Input;
    public Animator Anim;

    public PhysicsData Phx => Movement.Phx;
    public Vector2 InMove { get => Movement.RawInput; }
    public InputAction InJump { get => Input.Player.Jump; }
    public InputAction InDodge { get => Input.Player.Dodge; }

    public abstract void Enter();
    public abstract ePlayerState? Step();
    public abstract void Leave();
#

and PlayerStateBase's step, which implements the step from the interface returns ePlayerState?

#

when ePlayerState is nullable, i get an error that im not implementing the interface

#

but when i remove the ?, it works

#

any idea what could be causing this? ePlayerState needs to be nullable or else i can't return null in my state's Step method

compact ingot
#

conceptually/architectually what you probably need is the notion of a signal or trigger in your FSM

velvet mirage
#

the Step method contains the logic that runs on each frame of a state, so I use it to check the logic required to change states, let me post an example rq

# 
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using UnityEngine;

namespace Player
{
    public class State_Stand : PlayerStateBase
    {
        public State_Stand(PlayerStateMachine manager) : base(manager) { }

        public override void Enter() { CommonEnter(true, true, false, Phx.StandFriction, "stand"); }
        public override ePlayerState? Step() 
        {
            if (!Movement.FloorCheck()) return ePlayerState.Fall;
            if (InJump.WasPressedThisFrame()) return ePlayerState.Jump;
            if (InDodge.WasPressedThisFrame()) return ePlayerState.BackDash;
            if (InMove == Vector2.zero) return null;

            if (InMove.x != 0) return ePlayerState.GroundMove;
            else if (InMove.y < 0) return ePlayerState.Crouch;

            return null;
        }
        public override void Leave() { }
    }
}

velvet mirage
#

I dont think i follow, are you suggesting having a seperate type that handles the logic of changing states, and the state itself just runs whatever code the state needs per frame?

compact ingot
#

also consider that a FSM does not necessarly have to run every frame in every state

#

a "tick" or "step" could just be one of many signals you send to it for evaluation

velvet mirage
#

I'm sure you know what you're talking about, but for my purposes at least this is just the more convenient way to handle state logic for me, if the logic that changes state was seperate from the state code itself, the states would virtually all be completely empty and the state change logic itself would be a giant mess. In any case though this is just for a prototype, so if i end up finding some better examples later down the line ill consider it

compact ingot
velvet mirage
#

in any case though, do you have any idea why that nullable type would cause issues in this way?

Looking for strategy guidance.

I have a turn based multiplayer battle game. I have a battle state class which has.. many many members, nested and otherwise. It implements equality checking (I think IEquatable, I'd have to check). Turns are a series of player actions sent to the server, which calculates and replies with a series of "battle actions" (things that modify the underlying battle object).

Occasionally (like right now) I have a desync bug of some sort that's a pain to chase down. The battle state is represented in several places:

  • The server, in memory
  • Players "true" copy
  • Players "animated" copy (which lags behind the true copy and catches up as animations unspool).

Any thoughts/strategies on how to more effectively debug this class of bugs? Happy to talk through it if you have questions, or give a little video demo if it helps.

obsidian glade
misty glade
#

Yeah, I mean, I have that in the IEquatable checks. The issue is more.. figuring out when and where something went sideways.

#

Like, there's ... 5 different player actions, 27 different "battle actions", approaching 60 distinct abilities that all create a different series of battle actions.. if I make a tiny error (and to be fair, I'm getting good at just not) they're very hard to debug.

I was currently (just now) debating serializing the entire battle model and saving it from turn to turn so I could recreate it after the fact and examine it.. but a couple things.. battles tend to run about 50-100 turns, and the serialized byte stream is about 1k. Maybe that's small enough to work with? I'd probably also need to write my own tooling to examine it though..

obsidian glade
#

you have the hash or IEquatable (be sure it's actually capturing everything that constitutes state) and calculate it between every action and ability - as soon as it deviates, it must have been the last action

#

you don't need to save the entire state, just a hash of it so you can tell if it's not synced

misty glade
#

I could potentially do a hash and send it along with every turn.. compare it on the client to what it expects, both as it receives it, when the client is done processing it, and on both sides of the animation on the client as well

#

In the console log, you see things like "this turn contains 6 battle actions" - those are the messages with state changes that it sends to the client.. the client and the server both process these things in parallel.. but yeah, the desync bugs are really tedious to chase down

#

The other thing to consider is .. we're pretty close to opening this up to beta testers (friends and family, really) and... we're gonna want some easy way for bug reports to come in.. It might be nice to have the tooling and complete battle states saved so we can recreate issues on our end instead of relying on users to tell us what happened

obsidian glade
#

in the case of a turn with 6 battle actions, in my mind you'd have 6 different hash values computed, one after each action - essentially as granular as it can be while separating distinct systems/state changes

#

as for beta test bug reports, you can take a snapshot of the state after the fact if it's not synced and capture exactly which action caused it too

Anyone has looked into "SSL CA certificate error" when requesting with UWR?
This only happens to very small percentage of my players, and they have old Android devices.

There are plenty forum posts and search results in this Discord, but I'm pretty sure all the answers are wrong:

  • "The certificate is actually not valid": I'm using Cloudflare, and the certificate is 100% valid, checked both on PC and obviously it works for everyone else except those small percentage of players; those players can visit the API endpoint in browsers just fine.
  • "Those devices don't support TLS 1.3": Cloudflare supports TLS 1.0, 1.1, 1.2, and 1.3. On those devices I asked them to visit the API endpoint in browser (both Chrome and device built-in browser) directly and they all work. Checking their connection it also shows that it's connecting via TLS 1.2, so Cloudflare is also properly handling lower TLS versions.
  • "Just change your code accept to any certificate": yeah no, that's throwing away security completely.

The most relevant thing I've found is that Unity 2020's TLS has problems on Android, but apparently that issue has long been fixed, and I'm using Unity 2021.
There are also other people reporting issues here with not just Cloudflare but also big cloud providers like AWS, Azure, etc, so this doesn't seem like a Cloudflare issue either.

Any help would be appreciated.

Hi everyone, I'm trying to do builds with the build pipeline. I get the error
UnityException: Build path contains project built with "Create Visual Studio Solution" option, which is incompatible with current build settings. Consider building your project into an empty directory.

Here is my code.

hi guys, im trying to get this loop to wait each time for a new gridposition but i cant seem to get it working at all

i think i need to get all the gridposition tasks into a list/array then wait for the to be donethen iterate through the gridpositions after that and spawn everything?

        foreach (var unitData in unitDatas)
        {
            Vector3 unitSpawnWorldPos = LevelGrid.Instance.GetWorldPosition(await GetGridPosForUnitSpawn());
            
            Debug.Log("getting grid pos ");
            await Task.Delay(2000); // why is this needed to get the intended behaviour??? without this this loop executes instantlly and all units spawn on the same location
            
            GameObject unitGameObject = Instantiate(enemyUnitPrefab, unitSpawnWorldPos, Quaternion.identity);
            unitGameObject.GetComponent<Unit>();
            Unit unit = unitGameObject.GetComponent<Unit>();
            unit.SetUnitName(unitData.unitName);

I have problem with canvas and screen size.

My screen size is 946x532
My canvas size is 1920x1080
My UI image is 300x200
Mouse input returns value base on SCREEN SIZE, so up to 946x532

Problem is i want to position image at mouse position + its height (200)
If i use transform.position, problem is with getting image height which reports 200 but actually because of screen size it should be less (about 100)
If i use RectTransform.anchoredPosition, image again is not properly positioned since mouse input is based on screen size and not canvas size

I could use some hack of calculating ratio screen to canvas and multiply with mouse position or something but is there a cleaner way?
actual size of image on screen? Convert mouse position to canvas size?

#

this happens if i offset it by RectTransform.rect.height of image (panel with stats)

#

image should be next to elf (follows mouse)

any idea how you can import a MySQL client to unity? requiring the package using nuget ends with dependency errors, as they need different versions of the package I cannot place it manually

How do i make an object slippy ? I know that we need to assign the physics material to its collider... HOWEVER it does not work.
I wanna simulate an airhockey table.

My table is a cube, its box collider has a physic mat with all set to zero ( so it should be slippy ). My pug is a cube with multiple colliders, however when i drop it on the table its not... slippy... when i throw the pug at it, it almost stops directly. I wanna make it like ice basically.

Any ideas ?

Well generally it's also considered very bad practice to connect to a mysql database from your game

lunar jackal
#

it's a multiplayer game using mirror, and only the server should connect by mysql to the states database

You also didn't search very hard

Anyways, if you want to include a nuget package then you have to include all dependencies and resolve all conflicts

Chances are you have to disable validation for versions to prevent conflicts but that's risky af

Wanna create a airhockey table with a sliding pug.

Added physic materials to the table and a rigidbody to the pug... set friction to zero.

Pug does NOT slide...

the function I wanted didn't use template types, so it was fine

undone coral
#

but what are you trying to do? static methods that belong to classes with generic signatures are best declared protected or lower

What I wanted was to add a simple button on editor to activate a function in a template class, but apparently I didn't do it correctly

hmm but why

i mean what is the generic?

is that relevant?

okay well i thought i could help you model this better

it's the root cause of your problem

whatever it is you are doing*

It's fixed, I just wanted to know how to do with reflection because it might be useful

I tried in c# pure and it worked, but in unity it was giving error

it sounds like you tried something in C++

#

anyway we're just trying to help you

#

usually using generic signature abstract base classes for non-collections is a mistake

harsh current
#

I have a SO derived class that is generic, so it accepts arguments of multiple types (GameObject and several others). They had a function foo() and another foo(T value), but I couldn't reach the foo() on the custom inspector.

undone coral
#

"Generics are meant for collections, including of possibly 1 item"

undone coral
harsh current
#

class xyz<T> : ScriptableObject

undone coral
#

yeah

harsh current
#

anyway, since foo didn't use the generic type, I just made another base non-generic class and inherited from that instead (similar to a interface)

#

then it was reachable

undone coral
#

but what ARE those things? collections and... collections of a single value?

#

like a Tuple<T1, T2> is a collection of 2 values, that makes sense. but how do you differentiate between Result<T> and AbstractBaseWeapon<T> : MonoBehaviour where T : AbstractBaseWeapon<T>

#

they look different because i exaggerated it a bit, but they are sort of th esame

undone coral
#

@jolly token another perspective is that Result<T> is pretty radioactive

#

and really you should never do stuff like that

#

so maybe generics are only for collections

harsh current
#

It is a simple collection of values that send signals to observers any time a value from the collection is changed, nothing special

#

the editor tool is just for debugging

undone coral
#

Did you mean "UniRx"?

#

anyway i don't wanna bully you on this. there are pre-existing libraries that achieve these goals

#

you should try

# jolly token Pray give a better argument then 😄

Reason 1. They are mean (sic) to be used as Data Asset
Yes, Scriptableobjects are meant to be data.
Data is mutable.
The biggest problem with Scriptable Objects is that whilst they are mutable in the Editor they are not mutable at runtime.

Reason 2. You can do it with any C# Object
No you cannot. There is no facility in Unity to turn any C# Object into an asset

Reason 3. Don't bind yourself with Unity Inspector
The use of the Unity Inspector as a means of making references to other objects is a Unity standard. It stops you having to use .Find and .GetComponent unnecessarily.

Reason 4. It makes your project Unmaintainable
No more so than any other badly designed project. ScriptableObjects are not inherently 'unmaintainable' any more so than e.g. Monobehaviours.

Reason 5. It lacks of Expandability
As standard, no more so than Monobehaviours

Reason 6. There is (sic) ton of better Alternatives
What to these have to do with data containers?

Reason 7. You cannot turn off Domain/Scene Reload
Really?

Conclusion
OK, you dont like ScriptableObjects, I get it. But this is just nonsense. Use a Spreadsheet? Get real.

The biggest problem with Scriptable Objects is that whilst they are mutable in the Editor they are not mutable at runtime.
This is not true at all, it is still mutable at runtime and that's the point of so-called SOA. You should say "They do not persist in the build"

upbeat path
harsh current
#

I don't want to be mean, but observer is just a pattern. All patterns have pros and cons, and they are not supposed to be used alone in a project. You can always use alternatives to fix the cons of a pattern if the benefits are too big to pass

#

I think the question of "SOA vs Anti-SOA" is kind of meaningless, since it depends a lot on where they are pplied

This also means you are completely missing the point 😄 This ain't about using SO as data asset.

The use of the Unity Inspector as a means of making references to other objects is a Unity standard.
That does not mean you should assign everything from inspector.

What to these have to do with data containers?
I'm not talking about data containers if you understand my intention correctly

Others are also defending for 'general SO asset' not about 'SOA'

I guess a better discussion would be "where should we apply the observer pattern, and where we shouldn't"

Arguing the toss about design paradigms is better suited to a philosophy channel

Observer pattern is innocent in this discussion

#

I'd be question for any other 'design pattern' to be in ScriptableObject
Because they are data/asset, not logic or code component.

harsh current
#

I agree with your point that the main use of scriptable object is to have a shared container for data, but if someone finds a way to make their life easier by using SO, I don't see a problem about that.

In fact, if you follow a DDD paradigm, ScriptableObjets become invaluable

in my experience, as soon as you have a large (>10) collection of scriptable objects, even strictly as data assets, it is clunky

i like to use them this way

// rare, maybe 2 copies of these in your project
// used to recreate UI styles for UGUI
public class RareUIStyling : ScriptableObject {
 public Color highlight;
 public Color unselected;
}

// otherwise, big localizable thing
public class ConstantLocalizedGameDataObject : ScriptableObject {
 public ConstantLocalizedGameData gameData;
}

[Serializable] public class ConstantLocalizedGameData {
 ...

SOA is so bad

undone coral
# harsh current I guess a better discussion would be "where should we apply the observer pattern...

you can create an observer this way

using UniRx;
using UnityEngine;

public class GameController : MonoBehaviour {
 private ReactiveProperty<GameData> m_GameData = new();
 public IReadOnlyReactiveProperty<GameData> gameData => m_GameData;

 public static GameController instance { get; private set; }
 void Awake() {
  instance = this;
 }

 // other code calls this with
 // GameController.instance.DrawACard();
 public void DrawACard() {
  var gameData = m_GameData.Value.Copy();
  var nextCard = gameData.RemoveAt(0);
  gameData.Hand.Add(nextCard);
  m_GameData.Value = gameData;
 }
}

public struct GameData { 
  ...
  public GameData Copy() { ... }
}

that's it.

#

this encompasses 100% of the functionality of "observer" and "scriptable object architecture", and provides 10,000% more @harsh current

#

it's the right tool for that job

#

there is a lot of knowledge in that snippet:

  • most valuable game logic is coupled.
  • it takes 3 lines to implement a singleton correctly, and no more.
  • ultimately, your game data must be passed by value (should be declared a struct), because the only valid reference to it is GameController.instance.gameData
  • UniRx provides all the observe/subscribe functionality you need, including reactive properties.
  • you should only "mutate" (i.e., replace game data) in one place, and ensure the rules are followed with access modifiers

i am not a unity content creator, i'm not going to grow a beard and make a whole 600 minute youtube video series about this. but i'm also not wrong

@harsh current does this make sense?

SO are overrated but i'm using it as a data container for static stuff for different units, e.g. max health or sprite ref

undone coral
#

it would have been better to declare one prefab per unit in your tower defense game - this is, for example, how Bloons TD 6 is architected. probably every shipping, popular game at least

#

that's why in my experience, i extremely rarely use scriptable objects

#

the real reason people use them is because they like the comfort of certain UI patterns

#

making everything Assets icon-and-inspector UI driven is negative ROI

#

not for any other holistic or engineering reason

harsh current
undone coral
#

you can, of course, make a prefab, which has a ui

undone coral
#

you are advocating for "use scriptable objects instead of singleton monobehaviors," which in my experience is always a bad (negative ROI) option

jolly token
undone coral
#

and suddenly, everything that cathei wrote in that github, is indeed the most relevant

#

another reason this keeps coming up is that those stupid Unity produced videos really clicked for people

#

even though what they are advocating for is kind of stupid

#

@crude granite i cannot comprehend why Unity keeps those Scriptable Object Architecture videos up. i understand they get a lot of engagement, but they advocate for a 200% wrong design. they are like a political conspiracy video version of programming content - lots of engagement, negative value substance

harsh current
#

You are just assuming that people only use SO because of a popular video, but SO is just a monobehavior that doesn't belong to an object

#

it has its uses

i am just saying that i have thought about this a lot more than you, and i'm more motivated than anyone to adopt and advocate for good engineering practices

#

they should mark Scriptable Object as deprecated, and adopt a mature IDL like the protobuf spec to replace its best use case. it was a mistake, in DOTS, to not build around an IDL

magic onion is very close. you just can't build something big or mature around a spec in a C# class. they're too flexible

I also think smart pointers are better than traditional pointers, but it's not like I will tell everyone to switch to them. There are instances where traditional pointers might be a better choice, even if the difference is not that big.

#

some people just like the convenience of having serialization as built in, or some other features that come with SO

#

if there was a better alternative that was better in all aspects, people would use it

like let's say i made SOA illegal. i'm not exactly sure who would complain. if i made C++ illegal to use for new things, for every 1 person who complains about pointers, there would be 99 more who complain that suddenly, their cheap programmers are unusable

#

you can attach a component to a prefab, and have a bunch of prefabs in your Assets/ folder

#

it's like there's some mental block to use prefabs. it's inexplicable

#

unless... because unity didn't release "Prefab Architecture"

#

that invoked all this woo

#

here's the thing @harsh current , the kind of person who

#

can't handle like, create a prefab, then attaching the right component to it

#

and that's the 1 component

#

like a Unit component or whatever

#

then filling in the fields. this is the same thing as a scriptable object, as you've described it

#

the kind of person who can't handle that, isnt' going to be able to make scriptable objects either

#

they are hopelessly dumb. which isn't a real person anyway. nobody is that dumb

harsh current
#

But monobehaviours are different from scriptable objects in essence

jolly token
undone coral
#

that's true... but every single thing you want from scriptable objects you have to add on, which gives you monobehaviors at the end

#

everyone ends up reinventing monobehaviors with their scriptableobjects

#

"oh, how do i add lifecycle?"

#

there are only a few root causes to this disease

#

(1) people who watch that video. honestly they are the easiest to convince

#

(2) people who have a very, very limited knowledge of the unity api, and try to use scenes, and did not discover DontDestroyOnLoad.

#

(3) people who gain most of their programing knowledge from content creators. i find this audience the hardest to convince

harsh current
#

And which one am I?

undone coral
#

there are PERCEIVED causes, like "(4) what about people who need UI, like artists, to make game content?"

#

i mean, those people don't exist. there is nobody so stupid as to screw up attaching a component to a prefab. it's offensive.

#

nobody is going to screw that up

#

and besides, it's a UI anyway

upbeat path
#

@undone coral There is one huge flaw in your argument, you cannot transfer a monobehaviour from one gameobject to another

undone coral
#

there's so much enthusiasm for avoiding code, or making glorious editor UIs, for an audience of 0

#

a big part of this journey, this rejecting SOA journey, is accepting that Unity - really, all game development - has no audience of people who stubbornly refuse to learn the basics of programming. that is an actually extremely small amount of people! almost everyone i know with decent art skills - for example - is not hostile to excited to learn things, if that's someone you want to have access to your unity project for some reason

you can of course reference that prefab in many places

you are reinventing things
