Yeah, there could be a few problems. Your transform position could be under the ground, your raycast might not be tall enough to hit the ground, your layermask might not include the ground layer. Also it should still work regardless, but physics functions should be called in FixedUpdate instead of Update.

You can use Debug.DrawLine and Debug.DrawRay to visualize raycasts to help debug them.

[obtuse cape]

Ah I fixed it

The raycsst was not long enough

[hazy marten]

Glad you solved it 🙂

[obtuse cape]

Thanks for ur help! Legend

I have a problem though. When holding the spacebar, the player is able to still jump in thr air

How could I fix this?

i was making a pickup and drop system but when i put the game on, the gun just goes in a random place, locks in, and rotates with the camera, i drop it and pick it back up, then it starts raising while im spinning the camera around, is there something i can show for help?

i need so much help im so confused

[short osprey]

private IEnumerator PerformDash()
    {
        isDashing = true;
        dashesRemaining--;
        Vector2 dashDirection = new Vector2(Math.Sign(inputHorizontal), Math.Sign(inputVertical)).normalized;


        if (dashDirection == Vector2.zero)
        {
            dashDirection = new Vector2(transform.localScale.x, 0).normalized;
        }

        Debug.Log(dashDirection.x + " | " + dashDirection.y);

        Vector2 targetPosition = (Vector2)transform.position + dashDirection * playerData.DashLength;

        float elapsedTime = 0f;

        while (elapsedTime < playerData.DashTime)
        {
            rb.MovePosition(Vector2.Lerp(transform.position, targetPosition, elapsedTime / playerData.DashTime));
            elapsedTime += Time.deltaTime;
            yield return null;
        }
        isDashing = false;
    }

i wrote this coroutine to dash the player character in one of 8 directions (Left Up Down Right, and 4 in betweens)
it works, except for the fact that after arriving to targetPosition you stay suspended and unable to move for a little while before it ends, and i cant figure out why for the life of me....

even gravity doesnt affect me

[cosmic rain]

Your position lerp is not linear. It would move less and less each frame up to the point where you wouldn't see any movement with a naked eye.

Instead of using transform.position as a first parameter, cache the original position and use that instead.

[short osprey]

ohhh that makes sense. Thank you!

[frail parcel]

Trying to animate my player character running when input is detected and when it stops moving, but it never goes back to ide, here is the code, what am I doing wrong here? I checked the triggers too, they should be spelled correctly

[rigid island]

here is the fix

[frail parcel]

Uhhh I cannot see the screenshot is a little small

Ok thanks for being cryptic, I would like to learn why I messed up

I can see the little mark over the equals sign so I guess I will mess around with that, so thank you, I guess lol

[spring creek]

Wait. I'm a bit confused. You're checking if the players distance from origin is less than .01, then you set it to Idle? Is this a game where you stay near origin and it moves you just outwards a little to simulate movement?
Just so we understand better

[frail parcel]

Honestly it's a student project so I'm trying to set up the animation and stuff. I have not made this movement script so I cannot fully say what it's doing. From my understanding and so there's more context here is this part of the scripts as well

We have the player look towards the mouse position and then all those vector locations the camera is facing then adding them to the players transform when they input times the speed since we have different speed types

That's how I understand it at least. Though I'm sure I'm not seeing the full picture

[spring creek]

I would put a couple Debug.Logs in there to see the value of move

[hard viper]

some debug.Assert never hurts

assert statements are like butter. even if it looks sickenning, you can’t have too much

[swift falcon]

Hey all!

Loup&Snoop oh yeah you're the one I talked to

So I was just testing some stuff in my game

I was using the terraria sprite as a filler, such and such

I am using transform.rotateAround to rotate this butter ball around the player

However when he moves, I use a flip function to flip him

But I don't want the ball's position to flip so I can't child it

When I move the player however, then it causes the ball to move further away from the player and still orbit

How do I maintain this ball's distance from the player without parenting it? I tried using transform constraints and that did not work either

this.transform.RotateAround(player.position, Vector3.forward, 200 * Time.deltaTime);

[cosmic rain]

If you use proper flip, that should only affect the sprite renderer.

What exactly are you doing in your "flip function"?

[spring creek]

I'll just drop this here
https://docs.unity3d.com/ScriptReference/SpriteRenderer-flipX.html

[swift falcon]

Ah

I'm actually flipping it using transform

*= -1

[cosmic rain]

Yeah, that would affect all it's children.

[swift falcon]

Yeah

[cosmic rain]

Another way is to separate the controller from the visuals. Then you can do whatever you want with the visuals transform, while the orb would be parented to the controller.

[spring creek]

That is not usually a good way to do it. Sometimes it has its uses, but it doesn't seem like what you want here

[swift falcon]

Sorry I don't know this stuff

Because I don't have kids

[swift falcon]

Yes

Thank you :)

[swift falcon]

Thanks

[waxen burrow]

Howdy, while making a combat system I ran into some funny type stuff that I dont really know how to put into words but basically:

public void someMethod(){
  if(itemInstance is MeleeWeapon && (Weapon)itemInstance.AttackTriggered){}

Where Item is the parent of Weapon (which contains the AttackTriggered bool) and Weapon is the parent of MeleeWeapon
I have done something similar before without issue but unsure why I am unable to cast itemInstance as a MeeleWeapon after checking that it is a Weapon

[rigid island]

you're trying to cast bool to Weapon ? 🤔

[waxen burrow]

Im trying to case itemInstance as a Weapon to access the bool...

I get what you are pointing out however

[hexed pecan]

Does MeleeWeapon inherit from Weapon?

[swift falcon]

I'm back

So I have another question

Earlier I was making a ball revolve around the player

[hexed pecan]

if(itemInstance is MeleeWeapon meleeWpn && meleeWpn.AttackTriggered)

[swift falcon]

My idea is to revolve the ball a lot

And once it reaches a threshold, rotate it towards mouse pointer

And then shoot it

At that angle

My issue is, I've gotten mouse angle and everything

But when I apply:

        rb.AddForce(transform.forward * 5000, ForceMode2D.Impulse);

The ball just falls

It doesn't go at the angle I have rotated to

[lean sail]

you can most definitely type this all in 1 message..

[waxen burrow]

ah I see, I didnt know you could define something in the same line as type checking... Thats super helpful!

tyty

[swift falcon]

Sorry

Is it due to the fact that I'm only just setting the rb to kinematic before I launch it?

If my code was to work, it should launch this rb at the angle I've set its rotation to, right? However the ball just drops down.

In the inspector, I can see that the z-angle is being set correctly

[hexed pecan]

It's 2D, you probably want transform.up/right instead of forward

Forward in 2D is the direction the camera is facing

[swift falcon]

Sorry this does not fix it

Here's a video that shows you the debugging

And what happens, it does not work.

[swift falcon]

Either do not work, it does something very wacky but according to my code it should only be launching it once?

[swift falcon]

Thanks however that's helpful to know for the future

[swift falcon]

Anyone?

I'm still stuck :(

[vivid heart]

Please give me an idea of what scripts and interfaces I would need if I had to create a money management system in the sense that - there are different characters who have certain qualities as well as money, there is a certain service that deals with transferring money from the character to the hero following certain conditions or events. Please guide me in this direction from an architectural standpoint.

[lean sail]

im unsure what you mean by "characters who have certain qualities" so I cant answer there. As for the money management system, I would treat this as I would treat a health system. By having a component that holds and manages the characters money, anyone that has money will have this component. i dont really see a reason why you would want interfaces for this

the script that manages money basically needs to store a float and have a way to subtract from itself and give to someone else. Then other scripts would be storing the conditions and events that you describe, all they need to do is have a reference to your money manager script and know who to give it to when the condition is fulfilled

[round violet]

Hello,
Is there a way to update the duration of a "wait for seconds" after it was entered ?

example:

some code >> starts wait for seconds (duration = 3)
some other code >> add 5 for duration to whatever is left to wait for seconds

could this work using a var ? Does the wait for seconds checks how muc his left eac htime

[main shuttle]

Just WaitUntil then?

[round violet]

this could work but this means that i manually track the time myself ?

[main shuttle]

Yeah, I would WaitUntil your timer expires. Afaik you can't do what your saying.

[round violet]

ok ty

[swift falcon]

Can someone please help me with this

I'm still stuck

[plucky inlet]

Not sure where to put this. I am using the Vuplex.Webview plugin to show websites. Unfortunately, the plugin takes the chromium OS language instead of the URL it gets passed in. So if I pass in a german or english website, it always defaults to the english one inside Unity. Anyone in here with experience in that plugin and how to probably ignore the setting or override it? The documentation talks about command line tools, but they do not seem to have any effect.

[round violet]

is there a way to have something like WaitUntil but without frezzing the whole execution ?

[plucky inlet]

Use async tasks or similar for example and use callbacks to setup your logic

[round violet]

There is currently no async support in Visual Scripting so i guess ill do somehting else

[swift falcon]

Dude can someone help me please

I can not figure it out

And have trialled and errored

For a full day

[plucky inlet]

Ohh, sorry, did not know you are using visual scripting, my bad

[round violet]

No problem

[plucky inlet]

from the video there seems to be something wrong with the whole position calculation. I would comment out line by line and see, what happens when I turn on one thing after the other.

[swift falcon]

Sure, however

When I do that

It becomes apparent that the issue is with the rigidbody not the angle

Since when I do a rotation test with mouse, it works well.

[plucky inlet]

And did you check the suggestion about transform.forward?

[swift falcon]

Yes

That's what I did in the video

I showed that it's the same for each transform method

[plucky inlet]

Ah , got it. I will have a look at this later more closely, if its still an issue then. Gotta go, so sorry for the quick jump in and out

[swift falcon]

Sure thank you

[main shuttle]

https://docs.unity3d.com/ScriptReference/WaitUntil.html
You should just use it in a coroutine. You already used a coroutine for your WaitForSeconds thing, so I assumed you would just know how to do it, or search the docs.

[main shuttle]

Oh, if your using #763499475641172029, you should probably ask there.

[round violet]

yeah but i like asking here because most of the time the logic is the same

[round violet]

i didnt though about that

i'll try ty

Heyy, I have a really weird problem when I go to build my project. I have a buoyancy system set up that adds force to a list of transforms based on how far under the water they are. In the unity inspector, it's working fine, but once i build the project it stops working altogether, if anyone had any clues or tips on how I could potentially troubleshoot it further anything is appreciated, im very lost.

This is the code for the system. Its pretty much-written word for word from this tutorial. https://www.youtube.com/watch?v=iasDPyC0QOg

Troubleshoot with Debug.Log or the debugger as normal

As long as it's a dev build log statements will show up in the application log

sorry im still a little new to unity, how do I see the log in builds?

never mind thankyou google XD

[dawn nebula]

Hey so I've got a question related to code architecture. I've got a game where multiple NPCs need to coordinate the completion of one big task. Imagine some Sims-like situation where for dinner to start, there needs to be 4 NPCs at a table. They need to realize it's time for dinner, where to sit at the table, and that they should eat.

I want to be able to tell an individual NPC to leave dinner to go do something else, and I also want to be able to end dinner and "free" all NPCs at any moment. Any suggestions?
The NPCs have a task-based system where I can queue up a bunch of tasks for them to do and they'll work their way through the queue.
It's the group-based tasks that I'm unsure of how to best handle.

[hard viper]

the group task just needs a central point of contact to notify a group of NPCs to remove it

or, you could make group tasks erase (or outprioritize) their normal queue of tasks

i assume one NPC can only have one group task at a time, and that one group task takes priority over any other tasks

[hard viper]

actually, I would handle group tasks like a separate queue that takes higher priority

each time you check for next task to do: if priority queue has something, then do it. else do from normal queue

then you can ask one specific NPC to dump its priority queue at any time, which automatically returns it to its normal queue of tasks

and an NPC finishing a priority tasks will automatically start the next priority/normal task

then, for group management, group tasks would just need a manager with a collection: List<GroupTask> activeGroupTasks;
each group task has a list of all NPCs that are a part of it.

GroupTask : Task

and give Task a method public virtual void OnTaskDoneBy(NPC npc);

Task: OnTaskDoneBy(NPC npc) {}
does nothing

GroupTask: OnTaskDoneBy(NPC npc) {
participatingNPCs.Remove(noc);}

[hard viper]

does this help?

[steady moat]

Goal Oriented Planning Action can be a good way to handle most things you might face for this type of AI.

[dusk plume]

hi

i want to add android build thing in my unity version

[hard viper]

it’s basically a command pattern

[dusk plume]

but this is the big issue

[steady moat]

It is more than a command pattern. (GOAP)

[hard viper]

a bit more, but not too tough

[steady moat]

Enough to make a difference

[hard viper]

the hard part is the command pattern-like part. the easier part is managing priority

[steady moat]

The main difference is how it automatically find what available command there is given a state and a goal. It can construct multiple command to get to the end goal.

[hard viper]

yeah, i think that is a good idea

[dawn nebula]

Most of the AI would boil down to "here's an explicit list of things to do, go do it". I don't need something nearly as dynamic as the sims.

[steady moat]

For now*

[dawn nebula]

lol, well hopefully I don't fall into the scope creep trap 😛

[hard viper]

looking into GOAP, i think it is a good tool, but might be a lot bigger than needed here. depends on what he needs

[steady moat]

You decide, but I really believe that it is the best time to implement the pattern. Later, you might find yourself with the needs and it would cost you greatly.

[dawn nebula]

Like I will never be in a situation where an AI needs to get "warm" but needs to know to get fire wood, to light a fire to get warm.

In my case NPCs will be explicitly told to do something, and will be given explicit instructions on what to do.

[steady moat]

Not really what you said 😛

They need to realize it's time for dinner, where to sit at the table, and that they should eat.

[dawn nebula]

Fair I could see it being interpreted like that.

[hard viper]

GOAP is going to be a bit of a rabbit hole if you don’t need it

[dawn nebula]

I was more going for "these are the steps required to do dinner".

[hard viper]

as I see it, your main options are to use a priority queue or to use GOAP

[dawn nebula]

Currently I have a priority queue.

[hard viper]

to be clear, a priority queue AND a normal queue

so you dequeue from priority queue if there is a high priority task available. Otherwise, you go through normal queue

then tasks can be assigned different priority levels

NPC picks the highest priority queue that has at least one task in it

does that make sense?

[dawn nebula]

Ya it does. Though I'm wondering if I could end up in like... priority hell 😛 where I'm like "ok this task has high priority but this would should always be higher than that."

[hard viper]

the alternative is GOAP, which requires you to construct a whole list of actions to reach a specific goal. GOAP will make the NPCs smarter, but also more difficult for player to do exactly what they want.

[dawn nebula]

So I'm wondering if I should just have 1 list that acts like a queue, but also sorts by some defined priority.

[hard viper]

i would have an array of queues

iterate through array, and the first queue that has something in it: go do it.

array index corresponds to priority

when a new task is added, check to see if we need to put down current task

[fervent furnace]

one binary heap is enough, you can push tasks with same priority into it

[late lion]

It shouldn't be too complicated to implement a sorted-by-priority queue, assuming tasks can't have dynamic priorities.

[hard viper]

heap is faster. but also more complex to implement, i think

[fervent furnace]

if the priority of task is dynamic, it is terrible
the only way to pop is to iterate the whole array and remove as swap back

[hard viper]

if you have dynamic priorities, then GOAP is the way to go

priority queue[]/heap is simple for more simple behaviour imo

[fervent furnace]

ah, you can still use sorted set, but it runs slower than heap

delete then insert it bask

[hard viper]

i’m assuming total distinct priority levels is a very small number

[hard viper]

this can work if you just make a Comparer that compares priority then task age.

[dawn nebula]

Though tbf the priority of tasks is less my issue. It's more the coordination of a group task.

[hard viper]

do what I said before then

GroupTask : Task

Task: public virtual void OnDoneBy(NPC npc) {}

GroupTask: public override void OnDoneBy(NPC npc) {
participants.Remove(npc);
if (participants.Count == 0) {
whatToDoWhenDone
}
}

and GroupTask has a list of participants.

make sense?

[dawn nebula]

who is executing that task?

[rain minnow]

the TaskMaster . . .

[hard viper]

every NPC in the participants list has that group task in their queue/heap/whatever

GroupTaskManager can keep a collection of active group tasks. And GroupTask can report back to it when it is complete

[dawn nebula]

So the GroupTask is given a reference to whoever is managing this group task, and tells the manager when it's done?

[hard viper]

WhateverMonobehaviour decides what NPCs need to be a part of a given group task. Then it asks GroupTaskManager to assign. GroupTaskManager maintains a list of active group tasks. GroupTask’s constructor assigns the task to all the NPCs. When GroupTask is done, it tells GroupTaskManager it is done, and also tells WhateverMonobehaviour (that constrcuted it) that it is done.

[safe dagger]

Has anyone been able to get custom rich text tags working well/properly, I know of using links but that method sucks, I found a old forum post about editing the TMP_Text.cs to add my tags but I have the issue of the class being regenerated on the spot after editing it

[hard viper]

You probably need an interface: ITaskCompletionReceiver {
OnTaskComplete(Task task);}
This way GroupTasks can specifically hold a reference to the thing that needs to be notified, and tell it that it is done.

so WhateverMonobehaviour : ITaskCompletionReceiver

[dawn nebula]

alright I'll give something like that a try

I dont exactly like a task having reference to the thing that is managing it (which also has a reference to the task), but meh

[hard viper]

all tasks should keep a reference to the thing that needs to know when it is complete

dinner table should get notified when a task for setting the dinner table is done

a building should get notified when a wall-building task is done

Task could also store null, to notify nothing when it is done.

[dawn nebula]

no that makes sense

[dawn nebula]

I guess for some reason I thought the building having a reference to the tasks as well would be odd.

For this example.

[hard viper]

i mean the task has a reference to the building’s behaviour

probably a list of ITaskCompletionReceivers. So if you need to notify many behaviours when a given task is done, you can do it

[elfin quest]

Hello everyone, I want to make fixed time jump without using rigidbody. I'm currently using bezier curves for distance jumps and it works splendid, but I'm having tuble when I want to do a static jump, since the start and end points are exactly the same. Should this approach be working anyway and I've missed something? Or does bezier curves not work with same origin and end point?

In the latter case, does anyone have a solution I can use?

[leaden ice]

It's unclear how you're applying bezier curves to the implementation of a jump mechanic

[elfin quest]

Thanks for the reply, but the case was the first! Bezier curves work with the same start and end point, I was just using the wrong time variable. If you are interested on the solution I can share the code:

if (isSmashing)
        {
            if(currentSmashTime <= smashTime)
            {
                currentSmashTime += Time.fixedDeltaTime;
                Vector3 calculatedPoint = CalculateBezierPoint(currentSmashTime);
                skinHolder.transform.position = calculatedPoint;
            }
        }

This is called on the fixedUpdate.

 public Vector3 CalculateBezierPoint(float time)
    {
        float u = 1 - time;
        float tSquared = time * time;
        float uSquared = u * u;

        Vector3 calculatedPoint = uSquared * startPoint;
        calculatedPoint += 2 * u * time * controlPoint;
        calculatedPoint += tSquared * targetPoint;

        return calculatedPoint;
    }

This is the calculate function.

My issue was that this same character has 2 jumps, and the CalculateBezierPoint function, instead of asking for the time as an argument, it was using the time from the first jump, when I was testing the second one. I have this setup because I want the jumps to have a precise jump time, and the 2 jumps have different jumpTimes.

The variables startPoint, controlPoint and targetPoint are computed before the jump starts, on the same function that enables isSmashing.

When handling changing resolution or other graphics settings. Do most games load a default resolution then switch after reading the player prefs, or is there a way to get the application to load directly into the last resolution settings without having to run a script to change it?

[weak dove]

I have a scroll view populated by Buttons. It works fine, you can press the buttons but also drag to scroll up/down. The problem is these Buttons also have another component on them that implement the OnDrag events. This makes it so that you can drag on the buttons to scroll. Is there any way to disable the OnDrag events without disabling the component?

[leaden ice]

what component is it?

[weak dove]

It's a script I made to display item information in my game. It implements the OnDrag events so I can drag items between different inventory slots. In this case I don't want to be able to drag the items but I want to keep the component.

[leaden ice]

What you could do is remove the IDragHandler interface.
In the case when you want it draggable add an EventTrigger component and assign it to your functions.

otherwise leave it off

[weak dove]

ah I didn't know about EventTriggers, thank you!

    <Style src="project://database/Assets/UI%20Toolkit/UGUI/listEntry.uss?fileID=7433441132597879392&amp;guid=6ba520f1250203b4d948fbbe4b670fa3&amp;type=3#listEntry" />
    <ui:VisualElement name="parent" style="flex-grow: 1; flex-direction: row; width: auto; height: auto;">
        <ui:Label tabindex="-1" text="Label" parse-escape-sequences="true" display-tooltip-when-elided="true" name="name" class="nameLabel" style="width: 30%; margin-top: 4px; margin-right: 0; margin-bottom: 4px; margin-left: 2px;" />
        <ui:Label tabindex="-1" text="Label" parse-escape-sequences="true" display-tooltip-when-elided="true" name="score" class="scoreLabel" style="flex-shrink: 1; flex-grow: 1; width: 70%; margin-top: 4px; margin-right: 2px; margin-bottom: 4px; margin-left: 0;" />
    </ui:VisualElement>
</ui:UXML>

and I created a list to be the info for the ListView. But I son't know how to correctly do the binding, for the labels on the ListEntry visual tree asset to change according to the list content. Any Ideas how can I make that happen?

[karmic horizon]

Guys, why is my model not using the run animation?

[leaden ice]

looks like you've got a NullReferenceException to fix. Line 48 of InputManager.cs

[polar marten]

you can try taking some screenshots of the code on the screen, uploading it to chatgpt gpt4, and then ask it to transcribe the code for you

[karmic horizon]

https://paste.ofcode.org/AvYAAPMR3WcUpRnHGsWRsm

So what do i need to do?

[leaden ice]

fix your NRE

identify what is null on that line.

identify why it's null at that time.

fix it

as with all NREs

[wild jasper]

anyone any idea why the Debug in input name outputs the variable corectly but the debug in Continue says Null after that?

putting the things from continue into Input name makes it work but i wnat so save multiple things so this isnt an option

[leaden ice]

impossible to say since it's unclear when and where either of these functions are running

Could be on completely different instances of the script for example

[wild jasper]

so i input a text into a TMP input field, press enter, it shows me the correct variable, then i press the continue butteon directly underneath it wich callls Continue

[leaden ice]

You would have to show how all that stuff is set up

Any other scripts, the buttons, the input field, etc

[leaden ice]

Looks like you have two completely separate instances of the CreateCharacter script

Which falls in line with what I mentioned above

[wild jasper]

ohhhhhhh fuuuu thank you

didnt think of that at all you are my saviour

[obtuse cape]

Im trying to create a gun sway. But my pistol ends up looking down when pressing play. How am i able to change this so the pistol is aiming forward

public class GunSway : MonoBehaviour
{

    public float smooth;//float that holds the sway smoothness amount
    public float swayMultiplier;//increases/decreases the amount of sway on the gun

    private void Update()
    {
        //get the mouse inputs for both x and y 
        float mouseX = Input.GetAxisRaw("Mouse X") * swayMultiplier;
        float mouseY = Input.GetAxisRaw("Mouse Y") * swayMultiplier;

        //calculate the target rotation

        Quaternion xRotation = Quaternion.AngleAxis(-mouseY, Vector3.right);//Calculates target rotation on x axis, -mouseY because inverted otherwise
        Quaternion yRotation = Quaternion.AngleAxis(mouseX, Vector3.up);

        Quaternion targetRotation = xRotation * yRotation;//combine both x and y rotation

        //rotate the gun 
        transform.localRotation = Quaternion.Slerp(transform.localRotation, targetRotation, smooth * Time.deltaTime);

    }
}

[leaden ice]

First thing's first - make sure your 3D model was imported correctly into Unity. With tool handle rotation set to "local", double check that the blue arrow on the move tool is pointing out from the barrel of the gun model appropriately.

[obtuse cape]

The blue arrow is not pointing out the barrel

i have to always set the gun x rotation to -90 since its not pointing forward

so how can i use the -90 rotation intstead of transofmr.local rotation

@leaden ice

[leaden ice]

by far the simplest and best way to fix this is to re-export your gun model from Blender or elsewhere with the appropriate settings / orientation

[obtuse cape]

how should i import it with correct settings

[tranquil canopy]

Could someone help me with this log when i try to use google firebase?

[rigid island]

that thing is a shite show

your error seems to be related to you missing something IOS

probably XCode

the error , read it

usally says

[polar marten]

are you on a macOS device?

[tranquil canopy]

No

[polar marten]

did you set your target to iOS?

[tranquil canopy]

no

[rigid island]

just delete the IOS dll then

[tranquil canopy]

That's the weird fact

[polar marten]

@tranquil canopy how did you install the firebase package?

did you copy and paste something from somewhere?

was the thing you copied and pasted, a bunch of folders in windows into your Assets/ directory?

[tranquil canopy]

i thougt it but i didn't do it cause i thought i could break something

[tranquil canopy]

yep

[polar marten]

is that what the docs say to do?

[tranquil canopy]

i followed them carefully

[rigid island]

Its been a long time I think I had to do something like that

[lone wagon]

So i just opened my project i'v worked on for weeks. 2 days off and now this sht happends. Everything is deleted and terrain is completly destroyed,.
What is this sht??????????????

[rigid island]

lookup that error in google they have a github post on it @tranquil canopy

[polar marten]

i guess follow them again. https://firebase.google.com/docs/unity/setup

[rigid island]

not sure I see code question here, do you not have a Commit you can revert to ?

[tranquil canopy]

i'll try it... it could be like that... the video i've also seen did it with IOS too... could be that

[lone wagon]

Where should i post it then? im now here

[rigid island]

https://github.com/googlesamples/unity-jar-resolver/issues/622 issue @tranquil canopy

Thanks for bringing this to our attention. This issue could be solved by making sure you have the iOS build support in your Unity version.

Hi, having an issue with my camera - it resets/turns around just once. Code looks fine (no resets after time, etc..).
Since I'm having Camera as a child of Player object (with CharacterController) I feel like it may be connected to Logic/Physics frame sync, ...

I checked profiler and saw one spike exactly when the camera glitch happened. In that very spike there is no PhysicsFixedUpdate - is that correct?
Any ideas?

PS: I tried to move Movement to FixedUpdate and View to LateUpdate, didn't help => leads to horrible tearing of object edges which player is strafing around

[leaden ice]

Is m_inputView tied to mouse delta input?

[dawn sundial]

yep, by the "new" Unity Input System

[spring creek]

Brackeys special

[leaden ice]

If so you are improperly multiplying Time.deltaTime into mouse input. Mouse input is already framerate independent.

Remove Time.deltaTime from the mouse rotation calculation

(and adjust your view sensitivity down to compensate)

[dawn sundial]

trying...

[dawn sundial]

LEGEND!
Although - it still "freezes" a bit.
Before it froze and rotated the camera. Now it only freezes in that "spike".

[leaden ice]

well that's just a framerate hitch full stop

[dawn sundial]

And thank you very much for very quick and valid explanation of the delta. I didn't realize that at all

[dawn sundial]

weird, nothing in the scene almost, my pc is highend (4090, etc..)

learning profiler.. so not sure what to look at

It goes from 2ms to 6.5ms on EditorLoop - nothing else. Is that too much? 6.5 ms should be nothing, right?

Oh, I found this: Physics Queries: 265 hmm...

[lean sail]

that is indeed very little, 60 fps will be around 16.6ms per frame. You dont really need to worry about the editor loop because it wont exist in a build, although you can swap your profiler to edit mode to see what the issue really is. For me i had to swap on incremental gc once and that was about the only thing i had problems with in editor loop

[dawn sundial]

thanks @lean sail - I think that's alright, I didn't know there is other profiling information below the one I posted - basically I was looking at CPU only but the spike is actually in PHYSICS category

[leaden ice]

well it's not nothing. It's about 1/3rd of your frame budget for 60FPS, and basically the whole frame budget for 144FPS

but it's editor only

[dawn sundial]

hm, so you think that physics queries are alright to be 265? - I'm going to make a build and try

[leaden ice]

no definitely not

that's definitely a problem

[lean sail]

there should be a button that says Play mode which you swap to Edit mode? i think on the profiler. I dont have unity open but should be about accurate
Then you'll want to look at the hierarchy instead of just the graph alone, use the graph to identify spikes then click on the graph so the hierarchy can focus in on what is causing the spike

[dawn sundial]

Sharing my whole class for the PlayerController https://paste.ofcode.org/rj6pFtCrSPaZp4WCQuxdkK

[dawn sundial]

gonna try

I don't know, can't see anything special.. I mean I probably see the spike, but there is just standard stuff in the editor

[leaden ice]

looks like lots of GC allocation

inside OnGUI

[dawn sundial]

Yeah, it's the only thing that consumes the most of it..

I have one idea

well I had 2 custom Editor scripts that had been using the OnGui - I compeltely removed, it didn't help :/

[soft shard]

OnGUI can also refer to Canvases as well, you can try turning on "Deep Profile" and "Call Stacks" so you can see what functions might be causing GC.Collect for you

[trim rivet]

Can someone explain to me why the same operation produces two different results here ?

I'm beyond baffled

[dawn sundial]

I tried to turn of HUD (having only 1 canvas, so easy test) - same resut, but thanks for the tip! Going to try the deep profile

[simple egret]

+= when you add the height to a
-= when you add the height to b

[trim rivet]

why is the result of the addition positive x but the result of the subtraction not negative x ?

[simple egret]

(If you want the upper sphere to be above the collider you should add the radius, not subtract it)

[trim rivet]

why is the bottom sphere not within the collider?

the distance from the center should be the same value.

[dawn sundial]

when deep profiling on it runs like 30 FPS and doesn't create the spike :/

[lean sail]

you are subtracting the height and then the radius

if you want it at the bottom of the capsule (and inside), then just subtract the height and add the radius of the sphere

[trim rivet]

I just saw it, oh man I'm so stupid

🫂 🫂 🫂 🫂 basic Math where have you been all my life

[lean sail]

deep profiler does take more resources but im unsure about your issue, can you check if you have incremental GC turned on

[trim rivet]

thanks guys

[dawn sundial]

it was off

[lean sail]

turning it on should just solve this then

[dawn sundial]

wow, it really sovled the issue

[lean sail]

#archived-code-general message
i probably shouldve just suggested it more clearly here

[dawn sundial]

Thank you very much! I had no idea there is such an option and no idea why it was off (reading the documentation - it says it should be on by default).

[lean sail]

I saw that as well, no idea why mine was off either

[dawn sundial]

thanks a lot, spend hours on that, but I'm super happy for all the help @lean sail and @soft shard and @leaden ice - you tought me a lot today!

[tranquil canopy]

Hey, has someone ever used google firebase? i have 2 logs and i dont know how to solve them...

[vapid bluff]

Hello. I've noticed something weird while making my game. Everytime I press play, instead of showing the right tiles (image 1), the tiles are shown in random order (image 2). Is has something to do with the terrain sprites and the order that I put/copy-pasted them?

[leaden ice]

You'd have to explain what we're looking at

[vapid bluff]

the map of the game

I hope this video explains well the situation

[leaden ice]

Which is what? A tilemap? How is it populated?

[hard viper]

@heady iris I fixed my pausing bug from yesterday. My solution was to make better use of a class I made to allow me to run methods in EarlyFixedUpdate. It's just a singleton that invokes a delegate every fixed update, with super high execution order. Also LateFixedUpdate, to get things in immediately after collision callbacks are done.

[leaden ice]

Looks like you have some code doing world/chunk streaming. That code is populating the tilemap

That's the code responsible

[vapid bluff]

can I give you the code and see what's wrong there?

[leaden ice]

Well you can post it here. But I assume it's just because whatever is in the tilemap in the editor doesn't matter because you're streaming the data either from a noise function or some saved data

        // Normalize the movement direction if it's not zero
        if (moveDirection != Vector3.zero)
        {
            moveDirection.Normalize();
        }

        return moveDirection;
    }

TThis calculates the movement direction

        if (_normalMovement)
        {
            // Set movement speed based on input
            if (Input.GetKey(KeyCode.LeftShift) || Input.GetKey(KeyCode.RightShift))
            {
                currentSpeed = sprintSpeed;
            }
            else if (Input.GetKey(KeyCode.LeftControl) || Input.GetKey(KeyCode.RightControl))
            {
                currentSpeed = walkSpeed;
            }
            else
            {
                currentSpeed = jogSpeed;
            }

            // Move the player
            NormalMovement(CalculateMovementDirection());

        }
``` and this is what gets called in Update

    {

        // Translate the player's position based on the movement direction and amount
        //Vector3 newPosition = transform.position + movementDirection * currentSpeed * Time.deltaTime; //! Change to fixeddeltatime if using fixedupdate

        if (movementDirection != Vector3.zero)
        {

            // Calculate the rotation based on movement direction

            // Check if the rotation is close enough to the target rotation

            // Interpolate the rotation
            transform.rotation = Quaternion.Lerp(transform.rotation, _targetRotation, _rotationSpeed * Time.deltaTime);


            // Play correct animation
            if (currentSpeed == sprintSpeed)
            {
                this.GetComponent<PlayerAnimationHandler>().Player_Ani_Sprinting();

            }
            else if (currentSpeed == walkSpeed)

                this.GetComponent<PlayerAnimationHandler>().Player_Ani_Walking();
            }
            else

        {
            this.GetComponent<PlayerAnimationHandler>().Player_Ani_Idle();
        }

And this is the NormalMovement() function

Can't share the full script unfortunately

[leaden ice]

Well transform.Translate(Vector3.forward * currentSpeed * Time.deltaTime); on its own is fine assuming currentSpeed is the same

transform.rotation = Quaternion.Lerp(transform.rotation, _targetRotation, _rotationSpeed * Time.deltaTime); isn't quite a proper Lerp but it shouldn't matter all that much

[rich leaf]

whats wrong with this?

[leaden ice]

So given what you've shared I can't say what the issue is

[leaden ice]

https://gamedevbeginner.com/the-right-way-to-lerp-in-unity-with-examples/#lerp_slowing_down

[spring creek]

In short, the third variable is not a speed. It's not any kind of rate. It's a percent between the first two.
Multiplying it by deltaTime makes that value go up and down and look shaky. You never want to multiply it by deltaTime

[heady iris]

You know how interest is worth more if you compound it more frequently? It’s a similar situation

You wind up with behavior that varies with your framerate

[polar marten]

was this authored by chatgpt?

[hard viper]

is there a way to make a machine const editable in unity editor? like how Physics2D works?

[polar marten]

what is this? why is it rotating, and then moving and rotating at the same time?

[rich leaf]

Lol no

[polar marten]

you authored all of this?

is it from a tutorial?

[rich leaf]

It’s to make the movement when changing directions feel more realistic and less flipping on a dime

And yes I did it myself

Causes a smoothing effect as you’re changing directions and moving

[polar marten]

what is it?

what is being moved? like what's going on?

[rich leaf]

The player

The player gets rotated at some speed and once it’s within the threshold to the desired rotation it allows the player to start moving

[polar marten]

think very deeply about my question

big picture, what is going on

[rich leaf]

The game is top down 3D

[polar marten]

tell me what i need to know

okay that's very good

[hard viper]

so, quaternions are weird

[polar marten]

is the idea that right arrow always moves the player in positive x in the xz ground plane?

or does it move the character "right" relative to where it is facing, like driving a car?

[hard viper]

the best way to deal with quaternions is to try to avoid any sort of addition/subtraction or direct modification of ijkl individually

you want to use methods to multiply them, or rotate by

going back to your problem, _rotation speed has units of degrees/sec, and deltaTime has units of seconds. So you are using Quaternion.Lerp with the last number having units of degrees

which is incorrect

the last argument of a lerp/slerp needs to be dimensionless

[polar marten]

it seems weird to me, but is your goal that if my character is facing positive z (aka "screen up"), and i hit Right Arrow, it remains stationary and rotates towards ALMOST positive x, and then when it's within a certain threshold, start moving, and continue to rotate towards positive x?

[polar marten]

is that really the desired behavior?

[hard viper]

lerp/slerp's last argument brings you to a spot between the start and end (0-1) by the 3rd argument

[polar marten]

@rich leaf also, when sharing your project, are you using git?

i will tell you now, based on the code you shared, the simplest explanation for why the speeds are substantially different is that you guys do not comprehend what you are looking at. like probably you didn't save and commit your scene, which has a different sprint and walk speed than what is committed into git

because there is nothing wrong with transform.Translate(Vector3.forward * currentSpeed * Time.deltaTime); which is the only place where your character moves in this code snippet

so everything else is a red herring

@rich leaf does that make sense? ignore this quaternion story nonsense, it isn't causing the thing you are describing, although it is indeed glitchy

[rich leaf]

Game is top down, W corresponds to going up the screen (game is in xz plane), D corresponds to going to the right, etc...

The whole point of the rotation is that lets say I am going upwards (W) and want to change directions to the right by holding D, the players transform gets rotated and then the player is moved forward. However there is a threshold that has to be satisfied in the rotation (ie has to be 90% done the rotation) before it starts moving the player.

The idea for it (and works very well) is to smooth the rotation and prevent the players transform from just flip flopping to face the direction, which works for 2D but looks janky in 3D. You can balance the rotation thresholds to find a good middle ground between responsiveness and looking good

[rich leaf]

And for this, we use git and everything was up to date. My partner literally copy pasted the player prefab from my current scene i was working on into their new scene and noticed the discrepency

Also, the speeds are set in the script themselves and are not modified in the inspector

[summer oar]

I am confused

this code loads a texture from a byte[] array, and falls back on creating a solid color texture if the byte[] is invalid

private Texture2D GetTextureFromBitstream(byte[]? bitstream, UnityEngine.Color backgroundColorForInvalid, UnityEngine.Color key)
{
    if (bitstream == null || bitstream.Length == 0)
    {
        backgroundColorForInvalid = UnityEngine.Color.red;
        
        var solidTexture = new Texture2D(3, 3, TextureFormat.RGBA32, false);
        solidTexture.SetPixels(new[] { backgroundColorForInvalid, backgroundColorForInvalid, backgroundColorForInvalid, backgroundColorForInvalid, backgroundColorForInvalid, backgroundColorForInvalid, backgroundColorForInvalid, backgroundColorForInvalid, backgroundColorForInvalid });
        return solidTexture;
    }

    var imageTexture = new Texture2D(1, 1);
    imageTexture.LoadImage(bitstream);
    imageTexture.alphaIsTransparency = true;
        
    UnityEngine.Color[] colorData = imageTexture.GetPixels();
        
    for (var i = 0; i < colorData.Length; i++)
    {
        if (colorData[i] == key)
            colorData[i] = default;
    }
        
    imageTexture.SetPixelData(colorData, 0);
        
    return imageTexture;
}

In the case where the byte[] is valid and I get the image, everything's fine

[spring creek]

For a smooth rotation, consider replacing your Lerp with MoveTowards. Simpler to conceptualize for some people and in practice does the same thing sorta

[summer oar]

but in the case where it falls back to the solid color, I get a translucent gray texture in my UI

And I'm unsure why

[rich leaf]

will look into it thanks

[summer oar]

Because look at the code, it should be solid red

And it is if I use EncodeToPNG on it and save it to disk

[rich leaf]

What effects do i expect to see "incorrectly" using lerp? Everything looks smooth on my end

[cosmic rain]

It's not a linear interpolation and it will not actually reach the desired target.

[cosmic rain]

Are you sure it goes into that if block? Maybe add some logs? Also, you know you can use the debugger to step through the code and see exactly what's going on?

[summer oar]

ABSOLUTELY sure

and I'm well aware of the debugger, thank you

I wouldn't really be asking for help if I hadn't exhausted all other options

[cosmic rain]

Okay, then what do you see in the debugger when the issue occurs?

Might also be a matter of applying the changes to the texture.

[summer oar]

Like I said. If I use the debugger to call EncodeToPNG on the texture in the if block, I get a 3x3 red texture like I should

proof incoming

that is the texture

But it shows as the gray texture even in the Unity inspector

[cosmic rain]

Not sure what you mean by "use the debugger to call EncodeToPNG", but okay. What about the applying changes part?

[polar marten]

you can simply remove the rotation and see for yourself that the issue remains.* set the transform.forward to move direction immediately.

so something else is wrong

[hexed pecan]

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

[hexed pecan]

You need to call imageTexture.Apply() after SetPixelData

Looks like dlich pointed that out too

[polar marten]

focus on what i am saying

comment out this rotation and don't worry about it since it's not essential

[summer oar]

Rider lets you run C# code within the debugger

there's an interactive console

[summer oar]

waiwaiwait

that might just kill two bugs

[cosmic rain]

Ah, you're using that? There's that feature in VS to, but I'm not sure how reliable it is.
Regardless, my question still stands.

[mental rover]

I'm going to put my chips on one of you having a faulty keyboard such that the input isn't being read every frame

[polar marten]

lol

i mean he won't share the whole code file

[summer oar]

OH MY GOD

IT WAS APPLY

[mental rover]

just have to play along with the guessing game, hopefully we hear what the issue was when they find it

[summer oar]

ohhhkay so

calling Apply fixed solid textures

but now image textures are broken

the background where the two windows are, well

that should be Windows XP Bliss

now it's just a weird pattern

private Texture2D GetTextureFromBitstream(byte[]? bitstream, UnityEngine.Color backgroundColorForInvalid, UnityEngine.Color key)
{
    if (bitstream == null || bitstream.Length == 0)
    {
        var solidTexture = new Texture2D(1, 1, TextureFormat.RGBA32, false);
        solidTexture.SetPixels(new[] { backgroundColorForInvalid });
        solidTexture.Apply();
        return solidTexture;
    }

    var imageTexture = new Texture2D(1, 1);
    imageTexture.LoadImage(bitstream);
        
    UnityEngine.Color[] colorData = imageTexture.GetPixels();
        
    for (var i = 0; i < colorData.Length; i++)
    {
        if (colorData[i] == key)
            colorData[i] = default;
    }
        
    imageTexture.SetPixelData(colorData, 0);
    imageTexture.Apply();
        
    return imageTexture;
}

so, everything in the if statement is fine

everything after it isn't

Any idea what could be corrupting it?

Narrowed it down

UnityEngine.Color[] colorData = imageTexture.GetPixels();
            
for (var i = 0; i < colorData.Length; i++)
{
    if (colorData[i] == key)
        colorData[i] = default;
}
            
imageTexture.SetPixelData(colorData, 0);
imageTexture.Apply();

comment this code out and the texture loads fine, no corruption

but I need this code to do what it's written to do

SetPixels instead of SetPixelData

that fixed it

[naive inlet]

Hello, I need help with trying to add controller support for Prometeo Car Controller?

Working on a project with a group and we trying to do controller support for the car

[rich leaf]

Literally sent the whole code dude

[naive inlet]

Huh?

[rich leaf]

And no it’s pretty obvious by the animations that this isn’t happening

[mental rover]

I'd probably verify that with a debug log that shows both the frame number and the movement values rather than eyeballing the animations tbh

[spring creek]

I think they're talking to someone way above and just didn't do the reply button

[naive inlet]

Oh

[modern creek]

I'm getting DOTween errors when trying to delete a game object as part of the sequence on the tween. No worries, I can use OnComplete and it works fine. However, Demigiant's OnComplete replaces any other callback if one is set, and I need the OnComplete for other things (sequence queue).

Any ideas?

[leaden ice]

Have the OnComplete destroy the object and do the other thing too?

E.g. start a new sequence

[modern creek]

hm.. not sure I can easily. I have a sequence manager that's .. asking the components for a sequence, and then tacking it's own callback onto the sequence so it can fire the next.

Example, the "reward manager" can ask the "reward renderer" for a single sequence of grant 100 coins, and then stick them in a queue with a callback to fire the next one.. result:

but the .. i can only use oncomplete..

or maybe i could .. append a normal callback instead of using oncomplete

[leaden ice]

Can the sequence just do something silly like set a flag to destroy the object later or start a coroutine that does the same?

Also not sure I understand what the error is with putting Destroy in the sequence? What kind of error is it?

[modern creek]

I'm trying to get the error actually but DOTween seems to be soaking it somewhere.. I think it might be a problem with trying to destroy the object in the same frame as another part of the sequence is finishing? ie, if I tween scale from 0 to 0.5 sec and immediately append a callback to destroy, it .. just doesn't destroy the object. I'll show, one sec

OK, I've figured it out. And.. it's dumb. 🤦‍♂️

I overrode Destroy(UnityObject) to throw an exception when I tried to destroy a component on a gameobject (accidentally) instead of destroying the game object.

When I (finally) managed to get dotween's logging to show the underlying error, I found it.

The code I posted above even has it correct - it was only when I tried to Destroy(tile) instead of Destroy(tile.gameObject) did it fail.

[leaden ice]

ah

[modern creek]

(tile is some sort of object of mine)

[cursive moth]

Hi, I followed an advice I was given(because my terrain was disappearing), I rewrote the entire generation script so that it uses multiple connected closed sprite shapes instead of a single shape w many points because I was getting a warning message of max vertex limit being reached(which does appear to be solved now).
However, this new approach results in the terrain being very "unsmooth" and colliders are not nice because there are multiple instead of a single connected one.
I don't know what I am supposed to do in order to achieve a smooth appearance and nice feeling colliders(required for gameplay).
Here's the code
I'll provide an image showing what I mean by "unsmooth" terrain and colliders aswell.
This image shows a small gap between 2 sprite shapes even tho they are right next to each other, what am I supposed to do?

[modern creek]

works lovely now.. animations need some love but the whole sequencing and orchestration of it is functional

[leaden ice]

A bit of unsolicited advice - maybe have this sequencer insert a small (configurable) delay in between each thing too

[modern creek]

Yeah.. I think I'd make that part of the component that I'm asking for the sequence from.. like, "how long is your attention required".. and at the parent, instead of queue and dequeue only when the sequence is finished, I'd insert the next sequence after the first one has indicated "that's good enough".

ie: Sequence one takes 5 seconds but 3 seconds is good enough
Sequence two is 5 seconds but 3 seconds is also good enough

Orchestration: Start sequence 1 at 0.0 sec and 2 at 3.0 sec, and restore navigation after 6.0 sec

the animations themselves aren't great but I just needed something to ensure that I could.. queue up 6 animations at once and have them unspool nicely

[rich leaf]

Alright so going back to my p[roblem from earlier with the player speed being different on different hardware. When the players rigid body is removed, our movement speed is the same. However, the rigid body literally does not get called anywehre in the entire project solution (confirmed by searching through whole solution in VS). We've even commented out everything that had to do with playerRb in the code, but only when the component itself was removed did the movement match...

are there any settings in here that would be framerate dependend even if no scripts call the rigidbody?

[cursive moth]

interpolate

try disabling that

[rich leaf]

It seems like isKinematic being disabled also fixed it?

why would that be the case?

[cursive moth]

I am honestly not sure

I just had several instances of rb interpolation messing up the movement

I mean I have an idea of why it's happening but not sure if it's accurate

[rich leaf]

turning on isKinematic and disabling Interpolate fixed it too

And the weird part is this only seems to change things on their end... mine is unaffected

[cursive moth]

afaik, interpolate mimics the smooth movement of an rb(movement between fixed updates) by interpolating between the position before previous and previous position

and therefore, when combined with a transform based movement, it completely messes up everything

I am not sure if what I just said makes sense or is true

[leaden ice]

The constraints are weird to have when kinematic btw

But generally a kinematic body should be well behaved with direct transform motion

Although interpolation is completely unnecessary if you're moving it in Update via the transform

[rich leaf]

What constraints are weird?

[cursive moth]

probably

[spring creek]

And the y position

[rich leaf]

it seems to be the interpolation. What is this used for?

[cursive moth]

might be wrong but a basic idea

[rich leaf]

and how can you make it consistent across devices if you do want to interpolate?

[cursive moth]

you don't need interpolation if you are moving the object in Update()

[rich leaf]

is interpolation used for physics based movement?

[cursive moth]

it is used to smooth out the movement done in FixedUpdate() which happens less often than Update()

[rich leaf]

ahh that makes sense

thanks

[cursive moth]

bump

[leaden ice]

Interpolation is for when the object is moving in the fixed time step of the physics sim and needs to be smoothed out to the display framerate

If you're already moving in Update it's already in sync with the display framerate

Oops sorry I'm slow

[fickle lichen]

Hey I'm unable to understand number of commands in SpherecastCommand.ScheduleBatch(), how should I decide what number to put for "minCommandsPerJob" argument? Does it have to be amount of CPU cores?

[cosmic rain]

Probably trial, error, and profiling

[fickle lichen]

Alright seems to be even more vague because we don't know how many cores will the end user have

[cosmic rain]

Start from the total count and look at how long the job takes to perform. If it's too long, divide by 2.

[fickle lichen]

Well, here's a video and he says for 50 sphere casts and value of 10 it's going to result in 5 jobs, one for each core and one core left idle

[earnest karma]

can someone help me with my code? i'm trying to make it so the gameobject can be rotated when swiping across screen (like previewing a 3d model) and it works but when moving too fast it starts jerking back and forth

public class DragRotator : MonoBehaviour
{
    public float sensitivity = 1;
    public float speed = 0.5f;

    private Quaternion targetQuat;

    private void Start()
    {
        targetQuat = transform.rotation;
    }

    // Update is called once per frame
    void FixedUpdate()
    {
        if (Input.GetMouseButton(0))
        {
            float pitch = Input.GetAxis("Mouse Y") * sensitivity;
            float yaw = -Input.GetAxis("Mouse X") * sensitivity;
            
            Quaternion yawRotation = Quaternion.AngleAxis(yaw, Camera.main.transform.up);
            Quaternion pitchRotation = Quaternion.AngleAxis(pitch, Camera.main.transform.right);

            targetQuat = yawRotation * pitchRotation * targetQuat;
        }

        transform.rotation = Quaternion.Lerp(transform.rotation, targetQuat, speed * Time.deltaTime);
    }
}

[fickle lichen]

Shouldn't that happen in Update() method? Object being rotated is something that user can see, should see a change each frame

[cosmic rain]

You don't have to worry about the number of cores. They might not even be available at a time or busy with other jobs.

[earnest karma]

i was getting same problem when using update() though

[fickle lichen]

Okay thanks for your help by the way!

[spring creek]

You are multiplying the t parameter of lerp by deltaTime, which is wrong
Try just doing MoveTowards or look up the right way to use lerp

https://unity.huh.how/lerp

[cursive moth]

bump

[cosmic rain]

Where do you generate the collider?

[cursive moth]

it is auto generated by shapes

[cosmic rain]

What settings do you have on the sprite shape component?

[earnest karma]

didnt know about that, thank you!

[cosmic rain]

Try setting the offset to 0

[cursive moth]

you are a lifesaver :/

it completely fixed the collider it seems, the visuals are not there but I can live w that

[polar marten]

is this a multiplayer game? i think you are misinterpreting a lot of different things that are going on

[indigo plume]

im trying to make a moving platform, but the player keeps changing its scale with the floor and bugs it out, is there a way to keep it from affecting the scale?

[fervent furnace]

Because you setparent so child global scale will be affected

I remember there is an overload of setparent persevere global transformation

[indigo plume]

so what would be a different way to set the parent without affecting the scale?

[fervent furnace]

https://docs.unity3d.com/ScriptReference/Transform.SetParent.html

See the overload version

[indigo plume]

whats the overload version 💀 im very new to this lol

[fervent furnace]

Keep the child position rotation and scale in world space while setparent

[spring creek]

An overload is the same method, but with a different signature (the parameters you pass in).

public void SetParent(Transform parent, bool worldPositionStays);
This is the other overload. Make worldPositionStays true I guess.

"If true, the parent-relative position, scale and rotation are modified such that the object keeps the same world space position, rotation and scale as before."

[indigo plume]

where do i put the public void though? Do I just put it somewhere in the private class or inside the oncollision enter like i tried (and failed)

[spring creek]

public void should not be in there at all

[fervent furnace]

It is called method

[flat abyss]

Jesus guys, I'm sorry for the stupid question but I'm having a brain fart. How do we move an object backwards, regardless of rotation?

[spring creek]

collision.gameObject.transform.SetParent(transform, true);
It's EXACTLY what you had before, but with a comma true at the end

[indigo plume]

💀 oh

as i said

im very dumb and new to this

lmao

[spring creek]

You're fine. We all start the path somewhere

[spring creek]

What does backwards mean, if it doesn't have to do with rotation?

[flat abyss]

What it looks like. If the object is facing south, I want it to move north, if it's facing East, move west, etc

[fervent furnace]

Transform.forward

[flat abyss]

Exactly. The inverse of that

[spring creek]

So depending on which way it is... rotated, you want it to move backwards

-transform.forward

[flat abyss]

I'm having a bit of issues with localmoveZ -1

[indigo plume]

its still broken nvm

[flat abyss]

It's supposed to move one unity back regardless, but it keeps moving backwards. Perhaps it's because it has no parent

[spring creek]

You have errors. Resolve those first

[spring creek]

That seems like a separate issue. Maybe just show code at this point

Well, the issue is with PlayerMovement on line 35 inside Start. That's all I know from your video earlier
You are trying to access something that is Null

i checked line 35

and its just smth for the scoreText

is it bc the thingy is empty?

Google it

[leaden ice]

What about inside the project

[jovial spear]

inside the assets folder?

the space character is accepted?

[warm kraken]

this is my rotation function

but the issue is that sometimes it rotates endlessly

i heard its because i need to use quaternion rotation

[mellow sigil]

No, it's because you read Euler angles from transform

You need a separate variable to keep track of the current rotation

currentRotation = Vector3.Lerp(currentRotation, ...
transform.localEulerAngles = currentRotation;

also unrelated but incorrect use of Lerp

[somber tapir]

you are comparing 2 vectors which is almost always not true because of rounding.

[somber tapir]

it's not incorrect use, just different. In this case it is the wrong approach though.

[warm kraken]

whats the right approach on lerp in this case?

[mellow sigil]

https://gamedevbeginner.com/the-right-way-to-lerp-in-unity-with-examples/

[somber tapir]

Lerp(startPosition, endPosition, timer)

when timer is 0 the object will be at startPosition, when it is at 1 or higher it will be at endPosition. At 0.5 it will be in between both values.

[swift falcon]

Hey All!

I have an issue

Where I have a boomerang that constantly rotates, which causes my transform.position addition with transform.right to not go in a straight line.

I would like the sprite to go in a straight line, while rotating.

[leaden ice]

Make the SpriteRenderer a child object and only rotate the child. Move the parent as normal

[swift falcon]

Oh 🤦‍♂️ I didn't think of that, I really need to start thinking about the power of using children and parents.

Thank you so much

[dawn sundial]

Hi all, would anyone be able to help with CharacterMovement vs deltaTime vs fixedDeltaTime + Update/FixedUpdate/LateUpdate --> in other words, **the issue is: ** My character jumps higher when game is maximized (with more FPS).
I have this script, that covers all the movement, mosue look and jump with gravity. https://pastebin.com/GWk7JDcG

I'm trying all the things like spliting logic into Update, performing Movement in FixedUpdate. Using fixedDeltaTime instead of deltaTime. But nothing seems to fix my issue.

[somber tapir]

put all physics stuff into FixedUpdate. Also deltaTime and fixedDeltaTime is the same value in FixedUpdate() so it doesn't really matter.

[leaden ice]

newMovementSpeed.y += m_playerGravity; you forgot DeltaTime here

And you added it here which doesn't make sense:
newMovementSpeed += m_jumpingForce * Time.deltaTime;

Also why are you adding jump force every frame?

That should only happen once, right when you jump

Also you should just save all the DeltaTime stuff till the end, right before the Move call. Right now you have it confusingly mixed in all over the place

[dawn sundial]

I was following some tutorial since I was unable to make Camera as child object of a Player in FPS. The objects in scene where always flickering, etc.. so trying to understand now how it all works. I have done tons of 2D movement/cameras, learning the 3D these days for the first time.

Thanks both for your advices, going to check on that and try it.

Also appreciate pointing out the best practices on where to use the deltaTimes. Thank you!

[tidal shadow]

has anyone ever seen this type of behaviour?
never seen meshes do this kind of blinking thing
all my code that affects the character is disabled
the only thing i do, is spawn the character in which worked with no problem before i imported this character
there cant be a script inside the fbx model already can there?

seems like it was due to an animation it was uploaded with
removed the animation it had and now it no longer flickers

[dawn sundial]

I applied the changes and I think I alrady had it this way. Unfortunatelly now the object edges are flickering :/

[young moon]

Hello, I'm making a puzzle game that has daily levels. I have daily levels made for around 2 years but how would I best cycle through them? I was thinking of using the date together with the daily levels being in resources (they're json files) and then either having them all on a list, using Resource.Load or learning about Addressable.
My question is what would be the most efficient solution as I'll have 8 daily levels per day so I have a lot of files to work with.

[deft timber]

asset bundles, addressables

for sure not Resource.Load

or json as you said

[hard estuary]

In the past I've seen similar issues when someone added some sort of culling that was triggered by transparent objects.
In your case it's most likely badly implemented animation. Try putting the object on empty scene and see if it still flickers. If it's the case, I would suggest opening the animation in some sort of animation editing program and checking if everything is correct (e.g. scale is not set to 0 in some frames).

[tidal shadow]

i just removed the animation entirely inside blender
exported it back to unity and that solved it

[hard estuary]

Adressables seem convenient since your app will be downloaded faster if you implement it right (because particular addressables can be downloaded over time, e.g. only content for the current week, so the main app wont weight much).

Alternatively, you could use jsons and store them in some sort of database. It can be convenient in some projects.

[gray mural]

Hello, in my script I'm calculating the difference between start and current Rounded mouse position and assigning this Vector3 to my GameObject's Transform. Everything works fine when I assign Transform.position

item.transform.position = position;

But assigning Rigidbody2D.position makes my item go farther from the mouse every time if I move my mouse fast enough.
What's the reason?

item.rigidbody.position = position;

[jovial spear]

@leaden ice is & or ' illegal character?

[thin aurora]

\ / : *? ' | are illegal

[jovial spear]

& is safe?

[thin aurora]

No

You can assume that any special character except for - and _ is illegal

https://learn.microsoft.com/en-us/dotnet/api/system.io.path.getinvalidpathchars?view=net-8.0 Try the example to see all of them

[young moon]

I love the idea of adressables based on what you said but don't think it sounds needed for this project as my levels are very small json files. Altogether they're only some MBs. I was thinking jsons could be useful but how would I go around making a database efficiently? Still kind of new to these types of things c:

[leaden ice]

Could be yes

[jovial spear]

thanks, i'm renaming everything

[hard estuary]

I think databases are nice for projects that might want to update and/or download the data independently. E.g. you could update levels in external programs or let players upload their own levels. But if you don't need such features, I would probably abandon the idea of database. But if you're considering it, I would probably suggest using Firebase, because it has some support for Unity and there are some tutorials available.

When it comes to addressables, it's worth to mention you can include all of them in the initial build. I also think it would be easier to manage files compared to the Resources.Load.

[leaden ice]

Make a simple web application that serves the daily puzzles

[young moon]

Thanks for the advice~! It sounds like a database isn't for me but I'm happy for the input about them still.
I'll look into addressables and learn about it as that sounds like the right approach to my situation 😊

[jovial spear]

I still have this problem!

is there a way to disable a field in inspector if a given component is on the gameobject?

[rigid island]

custom inspector

[hard viper]

[rigid island]

they're not hard to make

just a pain in the butt

[hard viper]

i would honestly like an attribute to “disable if has component”

[rigid island]

I always do the question "Is this gonna benefit me in the long ? is it worth my time making it vs time saved using it?"

or if you're working with game designers I suppose

Why is my trail renderer only showing a tiny bit? I have time set to 10 seconds, and it is not lasting 10 seconds. Any ideas?

Also please forgive the extremely blurry second photo 😄

[latent latch]

Have you played with the curve? Maybe related

[leaden ice]

yeah the width curve seems to be set to 0 the whole way?

[quick elbow]

I have one key, and it's set to .0002

My objects are very tiny

Is that a problem?

[leaden ice]

potentially

that's really small

floating point precision will be a huge problem

[quick elbow]

Yeah... I'm displaying objects on a map in Unity where the map is 1m, so the aircraft are very small

[leaden ice]

Sounds like you're trying to sneak your way around doing a real floating origin implementation?

try making your objects bigger temporarily and see if the trail renderer is fixed

just to see if that's the problem

[quick elbow]

Not really. It's for an AR app. So I have a 1 meter map. And I need to see the aircraft on the map. The aircraft models are tiny. Like .004 meters or possibly smaller

[swift falcon]

Can anyone tell me how I can fix these errors?

[quick elbow]

I'll give that a shot and report back

[hard viper]

remember floating point precision is about relative values

single precision floats have significand holding the equivalent of 7 decimal digits

but they get sparser/denser depending on the order of magnitude

if the numbers are 1 vs 0.0002, there should not be issues with floating point precision

[quick elbow]

I tried making the width .01 and the min vertext distance .01, which sould be fine I'd imagine. And I have the same result. Unless it's because the object is moving very small amounts?

I imagine that is likely the culprit

[hard viper]

how big is the world?

like, what would constitute a typical big number in the game world

are your transforms at positions with x like 1000?

[quick elbow]

No they are very tiny. They move like .0001 every second

[hard viper]

but what is the actual raw position of the transforms

[quick elbow]

Changing the trail renderer time to something absurdly large like 500 seems to work. I just don't understand why

[thick socket]

if I set prevousHeadRotation = headrotation and headrotation changes...will prevousHeadRotation change also?

Quaternion headrotation;
    Quaternion firepointRotation;
    Quaternion prevousHeadRotation;
    Quaternion prevousFirepointRotation;

[quick elbow]

something like 0.5321234

Is how many decimal places

[leaden ice]

No Quaternion is a value type not a reference type

[quick elbow]

That is the Y value of one of my obejcts for example

[hard viper]

ok, so if all the numbers are within a few orders of magnitude of each other, then floating point precision shouldn’t be an issue

[thick socket]

awesome thanks! (for the future how to do I determine if something is a value type or reference type?)

[quick elbow]

x is like -0.04383245

Anbd they move about .001 a second

[hard viper]

just for reference: subtraction is a shitty opperation, because it gets unstable if you have big numbers thag are very close together.

[leaden ice]

Do you have time scaled?

[quick elbow]

Let me check, I don't believe so

is there a way to view in editor? Or do I have to log it?

[leaden ice]

In the Time settings

but if your code is setting it you won't see it there, not until runtime at least

[hard viper]

i think I understand now. And I agree with Praetor that your timescale is a likely issue

[strange scarab]

I have a 2D collider and when a player enters it I set the position of a particleSystem to that player. I'm not sure how to make it work for two players since it switches position between two players in collider.

[leaden ice]

how do you want it to work for two players?

[strange scarab]

I want it to create a new particle System when antoher player enters I then want to reference that in OntriggerStay and OnTriggerExit so I can set the position and then delete it.

Maybe I should store the particles in a dictionary and have the key be the players name and value be the newly created particlesystem so I can refer to the particleSystem for that player without interfearing with another players particles

Time to find out if c# has dictionarys

[knotty sun]

why not just put ther particle system on your players?

[strange scarab]

Because then the particles behave unnaturally when on player

and rotate with player

[knotty sun]

that is just a question of organising your hierarchy correctly

[strange scarab]

If I placed it directly on player it rotates with player so cant have that

[latent latch]

There's a few ways to forgo the rotational constraints

sure that works. Of course C# has a Dictionary.

[dusk plume]

why i can't add 2d character controller

[leaden ice]

There's no such thing.

Not built into Unity anyway

[strange scarab]

Ill just use a dictionary then probably bad practice to put a particleSystem in player

[dusk plume]

so how i make colision with character controller and 2d collide box

[leaden ice]

What do you mean by "character controller" exactly?
You can make a Rigidbody2D based one

[dusk plume]

for my case i prefer character controller but i mean the shape

look

[obtuse cape]

Why is my navmesh agent moving very far away from the baked navmesh surface

[dusk plume]

that's a triangle

i want to do it collide with the 2d box

[latent latch]

Pretty typical behavior and I do it a lot. Sticking systems onto player sibling objects that is

[dusk plume]

i am beginner to 2d unity so idk how to do it

[leaden ice]

the shape is called Capsule

use a Rigidbody2D and a CapsuleCollider2D

CharacterController is only for 3D

[gray mural]

Hello, I still have this issue. Any ideas?
I set Rigidbody2D.position instead of using Physics2D.SyncTransforms(), so I do need to use it for performance

[dusk plume]

i just realised that i don't need the character controller

i am very dumb

thanks you for the informations anyway

[strange scarab]

If I want to destroy a particle stored as the value in a dictionary can I just get the key and destroy it?

 Destroy(particleDictionary[collision.gameObject.name]);

[leaden ice]

yes but you probably want to remove it from the Dictionary too

also you shouldn't use name as the key

just use the GameObject itself

[simple egret]

(Know this will throw an exception if the key is not present in the dictionary at the time this instruction is executed)

[strange scarab]

it's a string as key then particleSystem as value then I'm removing it from dictionary after destroying it

[leaden ice]

if (particleDictionary.TryGetValue(collision.gameObject, out GameObject particleSystem)) {
  Destroy(particleSystem);
  particleDictionary.Remove(collision.gameObject);
}```

string key isn't good

names are not unique

and also .name produces garbage

the object itself is a fine key and more performant too

[strange scarab]

alright so if collision objects are unique ill use that thanks

[leaden ice]

ooh actually this is probably the cutest way:

if (particleDictionary.Remove(collision.gameObject, out GameObject particleSystem)) {
  Destroy(particleSystem);
}```

[strange scarab]

you don't have to loop through the dictionary to remove key values I thought

[leaden ice]

Where do you see a loop?

There's no loop here

loops are for while foreach and do : while

[strange scarab]

oh nvm awesome

you get a gold star

[quick elbow]

Sorry for the delayed reply, but my timescale is 1, it is not changed

[misty ibex]

Hey all, i seem to be having trouble with a BinarySpacePartitioning algorithm, in that i am trying to add a "room offset" parameter that gives some space between the rooms im splitting, but it seems that while it does give me more space between rooms, it's making all of the rooms smaller, which if you turn up the offset high enough, leaves empty/"zero" space rooms. I took the algorithm from a youtube tutorial, and one of the comments bought up this issue, saying that its due to how in the "makeSimpleRooms" function, the for statements are only executed (room.size.x - offset - offset) times. This means that when the offset is greater than 0, it reduces your available space by 2 * offset for both the width and height. The comment mentions that a simple fix could be to include the offset into the BinarySpacePartitioning() parameters, but I'm a bit lost on how exactly to do that. I've tired to add or multiply the dungeon size by the offset, but this still leads to microscopic rooms if the offset is high enough. Do you all have any suggestions? here are the scripts and some pics of the issue, thanks for your time.

Good luck with ur issue

Well u aren't most people. You are you. You gave your input now I am looking for helpful input. You've made it clear you don't want to help if it is inconvenient then asked for help on something else? Ok entitled much 😂

[pearl otter]

You should be adding the offset to the position, not subtracting from room size.

I think? I'm not fully understanding your code and why you're iterating the number of roomOffset

[misty ibex]

i should clarify that "oqajizujol" is the actual binary space partitioning algo, while "vibibahiyo" is the driver code that i stick onto the game object to run the generator with the variable parameters

[pearl otter]

Yeah I see that.

@misty ibex Can you try this code and see what happens?

    foreach (BoundsInt room in roomsList)

            {
                Vector2Int pos = new Vector2Int(room.min.x + col + roomOffset, room.min.y + row + roomOffset);
                floor.Add(pos);
            }
        }
    }
    return floor;
}

[magic wolf]

But regardless that resource was not helpful 😂 I don't know if it's because I'm on phone or if somehow it's supposed to be helpful that it says the exact same thing that my error line says. All it does is explain what a null reference is. Which I know. But I don't know why I have a null ref

[somber nacelle]

Surely you thought to click the links at the bottom of the page to go through the troubleshooting steps

[pearl otter]

@misty ibex I am curious, what kind of game are you creating?

[misty ibex]

okay so watching through that part of the video, what makeSimpleRooms is doing is basically going through all the rooms, applying the offset to each room's position, and then adding that possition to "floor" so that can be put in union with the rest of the floor's position hashset

[magic wolf]

I don't see those on my phone

im creating a top down shooter rougelite with procedurally generated levels.

So it all works out, heh

not yet, just wanted to refresh my memory on what make simple rooms is doing

i don't just copy code and not learn from it, i like to learn what it's doing, ya know? but it seems that i coded this part of the generation on a late night and maybe didn't understand what exactly was going on

i am trying your code now

[pearl otter]

Ah thats cool. Let me know the result of using the code I sent,

[pearl otter]

I always prefer to code/learn on my own, then I know exactly how everything works. Nothing is worse than going through broken confusing code from someone else.

yeeeaaaaa im confident on my coding skillz but i was NOT gonna be able to figure out procedrual generation on my own, lol

i could maybe learn from reading a few papers but hey, if there's a tutorial on it might as well us that as a springboard

The tutorial is pretty good, just has this one little hiccup. at the very least it helps me understand the algos i need and how to put it all together

that's all development is after all, its all a big puzzle

its all problem solving

[golden garnet]

Hey! Right now I'm trying to program in something to stop my camera from clipping into walls in my 3D platformer. As of right now, however, I'm not using Cinemachine. This project is pretty far along so I'm trying not to switch since it would mean refactoring a bunch of code thats already written, so I was hoping I could find a fix that I can implement into my camera as-is?

[somber nacelle]

you would likely need to use physics queries like raycasts/boxcasts/whatevercasts to check when the camera would collide with something when you move it

it's basically the same concept as manually checking for collisions when moving an object without physics

but the better answer, while it may take a bit of refactoring, would be to just use cinemachine which already has some components for that

[golden garnet]

My camera is set up like this. The main cam is attached to a parent object that has a script that controls its offset from the player. The camera itself has a script on it that allows the player to move it using the mouse and scroll wheel.

[misty ibex]

just tried the code, and i think i get what you were trying to do, but all i get is a giant ol room

[golden garnet]

zAdding a collider doesn't work since the movement of the camera is basically teleportation so collisions wont matter unfortunately

[pearl otter]

Haha

[delicate flax]

creating a camera is surprising, extremely complex.. that's why something like chinemachine exists 😅
not a code example, but this might help you out with creating a good custom camera, looking at what do to and not do, etc, etc

https://www.youtube.com/watch?v=C7307qRmlMI

[golden garnet]

I wish i knew about cinemachine when starting this project, would have made this so much easier 😅

[somber nacelle]

yes, this is why i suggested using physics queries like raycasts and not just throwing a collider on it

[golden garnet]

i'll have to look into that, any good places to start?

[somber nacelle]

i don't know of any specific resources that will teach you how to use raycasts and the like other than just looking at the docs 🤷‍♂️

[misty ibex]

i think you are on to something, the issue lies in the MakeSimpleRooms() function

in that i have to find a way to properly introduce the offset. All the offset should be doing is basically splitting the rooms apart from each other

[golden garnet]

https://pastebin.com/nXGsca7E
The code on the main camera, if it helps

[pearl otter]

What if you just do this?

Vector2Int pos = (Vector2Int)room.min + new Vector2Int(col + roomOffset, row + roomOffset);```

[misty ibex]

let me see if that helps

[misty ibex]

am i making this edit to the original code, or to the edited code you first suggested

as in are my for loops starting at 0 or at the offset

[pearl otter]

Original code

[pearl otter]

It should be 0.

You should only be using roomOffset in Vector2Int pos = (Vector2Int)room.min + new Vector2Int(col + roomOffset, row + roomOffset);

Although I believe that is doing what your code edited code would do, just in a different way 🤔

[misty ibex]

https://gdl.space/apizadinuq.cpp
this is the code i tried but it seems to just lead to big ol room

so i guess starting the for loop at the offset for some reason... works... ???

[pearl otter]

That is really strange

[misty ibex]

yeah

i think i know vaguely what;'s going

[pearl otter]

The only thing I can think of is it being something with room.min

[pearl otter]

What do you think it is?

[misty ibex]

essentially, the offset does separate the rooms from each other, but that comes at the cost of the blank space taking up the allocated "dungeon space"

in the comments of the video, someone pointed out this flaw, which is how i noticed, and they called it a "small flaw" that they think could be fixed by using the offset in the BSP() algo

though, im trying to figure out how that would work

[pearl otter]

Why would it make it look like one big room though?

[misty ibex]

here's exactly what the comment said:
1) In RoomFirstDungeonGenerator, the function CreateSimpleRooms does not create rooms of the minimum size. Indeed, it seems to me that the loop: for (int col = offset; col < room.size.x - offset; col++) is executed (room.size.x - offset - offset) times, which is fine when offset is zero, but reduces width (same for height) by 2 * offset. The most visible consequence is the reduction in the number of parts when the offset is increased, down to a zero number of parts. I would wait to see the end of the series to remove this small flaw, I think by adding the offset to BinarySpacePartitioning() to take it into account.

[misty ibex]

i think by executing (room.size.x) times instead of (room.size.x - offset - offset) times, you're basically moving the rooms over by the offset, but not seperating them from eachother

@pearl otter also interestingly enough, with the original code, the for loop runs for about 2200ish times with a offset of 2, but only about 240ish times with an offset of 5... while with edited code you suggested, it runs for 4900 times on the dot, no matter the offset

[pearl otter]

That is strange. I need to go for a bit but I asked chatgpt and it gave me this code. I don't think it will work but it would only take a second to test.

private HashSet<Vector2Int> makeSimpleRooms(List<BoundsInt> roomsList)
{
    HashSet<Vector2Int> floor = new HashSet<Vector2Int>();
    foreach (BoundsInt room in roomsList)
    {
        for (int col = room.min.x; col <= room.max.x; col++)
        {
            for (int row = room.min.y; row <= room.max.y; row++)
            {
                if (col < room.min.x + roomOffset || col > room.max.x - roomOffset ||
                    row < room.min.y + roomOffset || row > room.max.y - roomOffset)
                {
                    Vector2Int pos = new Vector2Int(col, row);
                    floor.Add(pos);
                }
            }
        }
    }
    return floor;
}

[misty ibex]

i appreciate your help but if you're just gonna run it past a damned AI i might as well just figure it out myself

[foggy maple]

don't ask chat gpt it actually sucks for programming

especially to help others

[misty ibex]

also, i think it would be helpful if you could tell me your logic/reasoning for your suggested edits, instead of just providing me the code

i really do appreciate your help on this and it's a tough pickle to be in, but i rather stuff be explained to me so i learn rather than just being given the answer
