[crimson canopy]

oh awesome

[rocky canyon]

then i use a little distance check that way any offsets i use are scaled accordingly..

(the distance text is offset 1/2 a unit above the object @ 1 unit away...)

using that simple conversion i can keep the offset looking good no matter how far from teh camera the tracked object is

so if i were 2 units away it'd be more like .25unit above the object.
if i were 10 units away it'd be like .05 units above the object.

that was really the only issue i had was the indicator would look differently depending on how far from teh camera it was.. so basically just normalized it

[crimson canopy]

@rich adder exposing my math rustiness, whats the best way to find this last number, since i dont want it to be a fraction directly relative to the distance between the two points, i just want it to be close to the player + a couple units

[wintry quarry]

I would just not add an entry to the dictionary in the first place until it has a value greater than 0

[drowsy flare]

I have a problem where I don't get the colors as expected when I draw a line using LineRenderer.
If I use: public Color color1; and select a color using the color picker in the editor, the line doesn't show up.
If I use: public Color color1 = Color.red; the line shows up and is red.

Any ideas?

[wintry quarry]

I think you're looking at a different LineRenderer in the inspector and in the scene

[rich adder]

was thinking something along the lines of horizontalPos = Mathf.Lerp(screenPos1, screenPos2, normalizedAngle/value

[drowsy flare]

Interesting

[crimson canopy]

alr lemme try

[drowsy flare]

I'm looking at my prefab which I instantiate ..

You are probably right, I just don't see how

[wintry quarry]

Double check that:

• Your prefab lives in the project window as an asset, not in the scene
• Your code is actually referencing and calling Instantiate on a reference to that prefab, not some other object, e.g. in the scene

[rich adder]

this is kinda pesudo code not literal.. screenpos would be the Screen.Width along with some calculations of getting the size of the indicator etc

[wintry quarry]

Also make sure you save the prefab.

[crimson canopy]

yea ik its just a different method so im gonna try it

[drowsy flare]

My scriptable objects reference the correct prefabs, and the prefabs are there and saved and in Assets, not in Scene

[rich adder]

mhm I can give a more practical example when I'm at the pc soon, a bit uncomfortable now to do now I'm on the go.
I'm sure you research on this problem there's plenty of modes done the way I suggest (this is how I also done it before)
Never should I needed physics for it / colliders.
that won't scale well especially if you ever decide to expand the viewport/change the size

[drowsy flare]

@wintry quarry Btw, I got it working yesterday with drawing the lines, worked out really pretty. Now I'm building it further with more lines between more objects 😛

That's why I need the color picker

[crimson canopy]

hm ok i see

[wintry quarry]

Maybe show some screenshots and code

[drowsy flare]

Hmm when debugging I actually get the correct colors (?):
Colors: RGBA(1.000, 0.000, 0.000, 0.000) color2: RGBA(0.519, 0.000, 0.000, 0.000)

Wait

That's fully transparent

HAHA

[wintry quarry]

ah- so you were just setting a transparent color in the inspector

[drowsy flare]

Yeah, didn't know it defaulted to fully transparent

Okay, looks super good now

Thanks again

[drowsy flare]

You wanna see it? 😄

[tacit prism]

back to my previous question

i was a dumbass and added a space to the statename in the editor, making it a completely different item i was trying to call, i love being an idiot

[rich adder]

Gotta love strings as keys :smh

[tacit prism]

imm quite the professional at messing things up in editor

[rich adder]

ehh strings very common to mess them up.. If you have multiple places you need it I usually go for a const at least its only changed in 1 spot (can only mess up once and not multiple times / worrying to update each one separate)

[shell sorrel]

think they ment it had a space in the serialized field not in code

[tacit prism]

this

[shell sorrel]

so work with a lot of designers and less technical people and i will often just do a .Trim on strings from input

and sometimes also a ToLower

deals with any white space on either side of it

other options are if there is a finate amount of them just use a Enum

[rich adder]

ahh okay even worse, the editor input fields are sometimes too small in some screens

[shell sorrel]

that way in editor its a dropdown

[shell sorrel]

yeah would be nice if there was maybe attribute that made the input monospace or something

[tender onyx]

Hey y'all. Working on a rougelike and need a little help with some UI work. I'm shooting for a Risk of Rain 2 style system to display powerups you've grabbed so it's easier for the player to know what all effects they have. I've seen some "close" guides for it, but nothing quite like what I'm looking for.

Any of y'all have some good resources (videos, forums, etc.) that could help? TIA

[rich adder]

you're never going to find a resource that does specifically what you want though, usually you lookup what you will need (breakdown each part into smaller parts) build it up yourself

[tender onyx]

fair enough, just never hurts to ask

[rich adder]

sure but its easier to make suggestions based on a more "generic" topic instead of specific "how to make UI like XYZ Game" etc

what specific features are you looking for ? what is missing in the resources you looked at ? and so on

[tardy lagoon]

i cant figure what is wrong with my code

[rich adder]

its a pretty obvious one, what does the error say ?

look carefully on how you structured this line

[tardy lagoon]

something with transform but ive been looking at it for 5 min now and just feel dumb

[cosmic dagger]

It's best to show the error you received . . .

[tardy lagoon]

mb

[cosmic dagger]

That's always a good start . . .

[rich adder]

as far as editor/compiler is concerned you're doing localScaleX * -1 localScaleY that makes no sense for it

[cosmic dagger]

Though, you can definitely spot this one . . .

[polar acorn]

Well, what's a -1 transform.localScale.y and why are you multiplying it with transform.localScale.x

[cosmic dagger]

Just look at every character on the error line . . .

[tardy lagoon]

idk what yall mean ig im just stupit but i cant figure it out

[polar acorn]

Well then, can you explain to us what transform.localScale.x * -1 transform.localScale.y means?

[tardy lagoon]

not really, flipping it up ig x is like forword and y is it

up

idk man im looking at tut

[grand snow]

taps sign

[polar acorn]

I mean, just looking at it like a math problem. What is a -1 transform.localScale.y? What does that mean?

[tardy lagoon]

go down one

[polar acorn]

transform.localScale.y is a number, so let's just substitute a random number for it, like seven. If you saw a math problem that looked like:
-1 7

Would that make sense to you?

[tardy lagoon]

idk 6

[polar acorn]

How?

[rich adder]

there is nothing in between, how would you know (to add subtrace, etc.)

[grand snow]

someone plz just tell them its invalid syntax

[polar acorn]

we have

so has the compiler

and so has the tutorial they copied this from without thinking

[grand snow]

ah the old "i swear i did exactly what the tutorial said"

[polar acorn]

And I figured by asking a patently absurd math question they'd see where the problem is and go double check that exact spot

[rich adder]

oh this is from a tutorial too ? that gives you even more easier solution to just compare the two

[polar acorn]

But patently absurd math problems only work on people who have ever looked at a math problem before

so I guess that doesn't work any more

[rich adder]

can you send the tutorial plz

[tardy lagoon]

https://www.youtube.com/watch?v=swCFvAxYKBE&list=PLSR2vNOypvs5yLsbqZc0e6RdqNnP1eGIc&index=4

[rich adder]

ok now. compare these two images

[slender nymph]

now compare that line, character by character, with what you have

[polar acorn]

"I did it exactly like the tutorial so why does theirs work and mine doesn't" counter:
Number of times it wasn't exactly like the tutorial: 197
Number of times it was exactly like the tutorial: 5
Number of times the code literally did not exist: 1
2022-07-19 to 2025-10-16

[rich adder]

hey only 197 between 3 years, not bad average

[polar acorn]

Wait a minute you're the same person I've Counter'd at last time

You really need to actually look at the code you're copying. Or, you know, actually take a second of effort to understand it

[rich adder]

glad I grew up with those games where you compare two images to find the mismatched/difference in items, comes to good use 💪

[slender nymph]

"They're the same picture" - 197 people since 2022-07-19

[tardy lagoon]

what the comma i added that and there is still a problem

[slender nymph]

what is the new problem

[polar acorn]

What does it look like now? What's the current error say?

[slender nymph]

check your spelling

[rich adder]

jfc

[tardy lagoon]

idk what refrnce im missing

[rich adder]

localscale doesn't exist

[polar acorn]

So, look at the error

[slender nymph]

you're not missing a reference. you've misspelled localScale

[polar acorn]

compare it to the thing literally right next to it

and see what's different

I, honestly, cannot understand how you don't see this

The only explanation is that you literally are not looking

[rich adder]

I was gonna say troll post but then I tell myself Hanlon's razor...

[polar acorn]

Please, for everyone's sake, take half a second to look at the thing that's underlined in bright red

and think "Hm... this didn't happen last time I typed this. I wonder what the difference is?"

This is a channel for programming. Not Sesame Street.

[rich adder]

another interesting thing... when you type and use the . operator.. you get suggestions on valid things that are part of it, put it to use and select those items... don't just blindly copy something, take the time to see whats happening as you write these things.
understanding basic concepts like . access can go a long way if you're trying to make something as complex as a game..

[warm jetty]

Hey, I'm very new to this kind of stuff and I've run into a problem twice. I'm attaching a script to a button to increase a value on click, but the only options I'm getting are 'No Function' or MonoBehaviour with the drop-down menu only containing a string option.

[slender nymph]

https://unity.huh.how/unity-events/incorrect-assignment

[warm jetty]

Thank you 🙏

[limpid sundial]

Hi guys. I have around 1.2k frames (at most) on a single 2d character. for a much cleaner game making is it better to separate them? (ie. walking North, Flying North,SE,W or just dump them in the sprite renderer and remember their count? I'm planning on using them on a small scale 2d multiplayer rpg. around 5-10 ppl?

[sour fulcrum]

Could you elaborate on remembering the count?

[prime cobalt]

Does anyone have any idea how this could be null considering it checks if any of the values are null?

[polar acorn]

_GridController

Oh, wait, that one is just outside the others

[prime cobalt]

First check is for if it's null

[polar acorn]

I thought they were allin a row

but some of them are nested

[prime cobalt]

I just forgot that I had a nested check for the playerPawn as well when I made the check for it

[polar acorn]

Are you sure that's the line the error is on? Show the stack trace

[limpid sundial]

for ex the count on the "walking north" sprite count is frame 100-120 etc.

[ivory bobcat]

Can you show us the stacktrace and line numbers for the code

[sour fulcrum]

Is whatever running this code the right instance of it?

[prime cobalt]

NullReferenceException: Object reference not set to an instance of an object
GridController.HandlePlayerTileSelection (UnityEngine.Vector3 inputMousePos, CharacterPawn inputPlayer, Mouse inputMouse, System.Boolean overRidePreviousPos) (at Assets/Scripts/Grid/GridController.cs:184)
GameHandler.Update () (at Assets/Scripts/GameHandler.cs:110)

[polar acorn]

Okay, what's line 184 of GridController.cs?

[polar acorn]

So that's the line that has a null on it

You put all your null checks on a completely unrelated line

So either GameHandler.instance or GameHandler.instance.playerCursor is null

[prime cobalt]

Hmm ok

Ah ok I managed to fix it, thanks!

[sonic dome]

why is the gravity so bad

its the default 9.81

and i try to play around with the values here

but it still feels like my player is a feather

also i checked something why is it that the cube falls faster than the cylinder?

[hot wadi]

Are u attaching the script the cylinder?

[rough granite]

Well going by the values here one could assume you are a 30kg mass with a jump force of 400N of course you're going to feel as light as a feather (this is assuming you wrote your code nicely) cause at that rate you would have an initial velocity of 13m/s or 46 ish km/h which is insane.

Went on a tangent, for why the cube falling faster no clue realistically it shouldn't

[hot wadi]

The mass does not affect the falling speed

[rough granite]

I know lol it affects the jumping speed though

That's why i said i had no clue why the cube fell faster

[rough granite]

Wait huh i might've done some math wrong :/ my bad pretty sure it's an initial acceleration upwards at 3.5m/s^2

[naive pawn]

this is pretty typical
most platformers/games have quite high gravity compared to irl to make it feel nicer, and there also might be a higher gravity when falling (a higher "down gravity")

try looking up the platformer toolkit by gmtk to play around with some values there

[naive pawn]

you were right the first time im pretty sure

[rough granite]

Idk it's late

[rough granite]

No no i forgot to account for the downward force of gravity so i think i was wrong :/

[naive pawn]

this is an impulse force, gravity is a continuous force

you can't just subtract them directly i don't think

[rough granite]

Fair point

[naive pawn]

if it's applied as an Impulse force then it's not actually force, it's momentum

[bronze fossil]

Hello,

I have a game concept in my mind and I have never used unity or any engine before or have made any games before
I wanted to ask for your opinion

this game has some unique features such as:

1. Needs to have an always on top transparent window
2. Needs to be able to change desktop wallpaper of the user(the wallpaper will be dynamic as well like in rainmeter)
3. Needs to be an app that should run on "statup"

can this be feasible in unity?
if not if possible please provide me any info about what would fit my requirement

currently i wanna make it in windows 11
thank you very much

[sour fulcrum]

have you googled any of these

[hot wadi]

Sounds like something u can do with Winform. Unity don't have much control over the system like this I'm afraid

[sour fulcrum]

c# does

[hot wadi]

Winform uses C#

[rough granite]

So does unity i doubt there is much stopping it if you actually fully knew what you were doing

[sonic dome]

why would that be

isnt it w = mg

[rough granite]

Cause gravity doesn't play favourites the acceleration you fall from gravity no matter how heavy you are is always 9.81m/s^2 (assuming you are on earth)

[sonic dome]

hmm interesting

okay now im at the point of making guns

now when i shoot i tried make a rigidbody bullet

but when i shoot it at high speed it just bypasses the collisions

assuming its faster than the game can calcuate the collision

but bullets are supposed to be fast

is rb not a good idea?

[rough granite]

I would just recommend using a raycast

And dont create an actual bullet object

[sonic dome]

how do games use rb or they dont at all?

[rough granite]

For what bullets?

[sonic dome]

yes

[rough granite]

They would change the collision type from discrete to continuous iirc

[sonic dome]

oo let me try that

[rough granite]

But again if you want realistic speed bullets us a raycast

[sonic dome]

wouldnt it be more realsitc when phys is being simulated

[sonic dome]

yep that worked well thanks

[sour fulcrum]

realism isnt usually the initial goal in most games. what feels fun and good is

[sonic dome]

that makes sense

[rough granite]

For the bullet speed? Im sure you could just find the distance traveled and using a set speed for that bullet say (ruudementary numbers) a range of 500m at a velocity of 1000m/s would make it half a second travel time so you just check half a second after they click if the user has a hitbox at the point the raycast first found

Though at that rate you'd need to account for gravity when checking so you'd add (1/2)-9.8*{TravelTime}^2 to the height

[spark vault]

Anyone willing to answer a few noob questions on a voice chat? Mostly just very basic stuff so i can understand the concepts without getting into details.. but specifically looking for someone with some experience with Server-Host-Client experience. (Like Server handles the verification and HP, Damage calculations, then sends broadcast back to Clients.. haha im gettin into the weeds here, I guess I need 2 people, one that understand Hierarchy for basic questions in unity, and one that maybe has exp with a multiplayer game, and the Authority for stuff.. idk im new, any help appreciated, thanks!

[rough granite]

Sorry i dont think anyone that is skilled enough will willing join a vc

[spark vault]

It's kinda a stretch for the multiplayer ask, but i still have questions on like.. "where do you store the GameManager.cs or EventManager.cs in the project? Make a Main Scene that remains open to hold these and then other scenes reference it or do you just add it to all scenes? "

[keen dew]

You can post the questions to #1390346492019212368

[rough granite]

Multiplayer questions can be asked in #1390346492019212368 but for things that you need to persist across scenes like settings you can either make an object and call DontDestroyOnLoad or you can use a static class which as far as i know keeps data between scenes as it's just one instance of that class

[brisk ibex]

Does anyone have any advice on how I can generate text onto a texture2d in the dumbest way possible?

I don't want to use any of the UI stuff if possible.

[hot wadi]

U are missing the point. It's trying to find the most efficient solution for a problem.
Yes, u can do pretty much anything with Unity, but then u will need to adopt the Windows API to do the rendering and event work, which Winform already supports.
Technically Unity is overkill for this task, especially for beginner. Winform is way simpler and more lightweight

[sour fulcrum]

Technically Unity is overkill for this task
you don't know enough about the task

[rough granite]

Besides them wanting a transparent window, changes desktop wallpaper, and it booting on startup which as far as i know is possible in unity we dont lol

[sour fulcrum]

..yes

eg. if any of this uses 3d rendering

winform is far less enticing, no?

[rough granite]

Kinda sounds like they wanna make wallpaper engine 2.0 :/

[sour fulcrum]

which is fine if they want to

[rough granite]

Totally

[sonic dome]

thanks very helpful

[rough granite]

Im shocked you read all that i was just yapping cause im tired but dont wanna sleep

[sonic dome]

im back to unity after like 4 years this feels refreashing

[spark vault]

Then answer my questions on VC lol, I feel like im over-analyzing the basics

[hot wadi]

They specifically said like Rainmeter which uses Win32 API. U are just assuming things as I do. I already said my points

[sour fulcrum]

i didn't assume anything

[sour fulcrum]

no vc's on this server, sorry

[spark vault]

I know but there is options, if anyone is willing.. im new and just want to ask some basic questions because I did the whole 'watch 15261326 tutorials, and learn nothing' I don't wanna do spaghetti code, just have some basic questions.. maybe ill go to fiver and look for unity dev ha

[bronze fossil]

yea i tried asking some ais and the ans is that unity is good for the game but the features it requires may not be possible to implement in unity
specifically the 2nd point

[bronze fossil]

oh i c

[sour fulcrum]

i asked if you googled them 😄

ai is shit

[bronze fossil]

oh ok

[sour fulcrum]

also be sure to ask about doing it in c# too

[bronze fossil]

ooo

[sour fulcrum]

unity uses c# so stuff done in c# can be done via unity

[bronze fossil]

ooo i c

[bronze fossil]

you see i want to do something like this

so when you are using your pc on a programmed time certain entity comes to your screen
you have an mechanism/interactive way of acquiring this entity
when you acquire this entity you can set it in your background wallpaper
and you know it's that type of cozy kinda game

ok so the entities are in 3d
and the wallpaper is also live so the entities can move in it

so the window should be transparent and always on top for when the entities come
and on the desktop page the window will be behind the folders

[rough granite]

i would not recommend Winform then

[bronze fossil]

ooo

so i go with unity ig?

[spark vault]

i feel like a lot of people will feel like that's a virus unless you make reference to the old Tomogachii lol

[rough granite]

well it'll be a better choice than trying to make a game from nothing

[bronze fossil]

lol

[bronze fossil]

ooo i c

alright thanks

[spark vault]

maybe consider the reference when advertising lol

[rough granite]

not sure why but when you said entities i only thought of like cod zombies :/

[bronze fossil]

uhhh lol

[bronze fossil]

ooo ye

[rough granite]

but do you mean like they character (say a cat) would be behind everything like in the wallpaper or it would be ontop of your applications?

[spark vault]

"demonic entities interactive wallpaper!" lol

[bronze fossil]

the ones you are able to aquire will be in the wallpaper itself so they are not shown when you are using someother app

but there will also be a always on top window in which new entity will come (on a programmed time) for you to catch

[rough granite]

ah so like a two window setup where one would be like Bongo cats tiny window with the gifts and the other like wallpaper engines wallpapers?

[bronze fossil]

yea exactly

[rough granite]

i mean im not sure how to do it myself but i am fairly certain it is possible

[bronze fossil]

ooo that's great thank you very much

[sonic dome]

is onNetworkSpawn still a thing?

cuz i cant find it

[hexed terrace]

ask in #1390346492019212368

(and check the docs for the version you're using)

[sonic dome]

yea found it thanks

how do i even debug this

[midnight plover]

Find out, who is moving your player and from there go through the code to see, what is actually happening

[sonic dome]

understood

thanks

[lost moss]

Confused Why This Isnt Working? My Animations Arent Playing?

[sonic dome]

How can i set a custom spawn location to my network manager in netcode?

[midnight plover]

Did you already google that?

[sonic dome]

i somewhat did but was hoping for a simple alt

but anyways ill do it later atp

where does this audio come from i thought it was the GlobalVol

[midnight plover]

Wild guess, you are creating two cameras somewhere. Just serach for the component AudioListener as it says

[sonic dome]

ooo its the main cameraaaaaaa

yea

thanks

Okay now the million dollar question i searched online but it seems like I just do the normal instanciate to add objects to the scene but for some reason it doesn't seem to work

Why could that be

And yea the object i try to add has the network object script

[midnight plover]

#1390346492019212368 might be a better palce to ask if its about the whole setup of the game and not a specific code part 🙂

[sonic dome]

Why does it have to be a post channel 🥹

[limpid thistle]

The Pivot of my object in the prefab and in the scene are correct, but when i try to rotate it with this code:

                rb.AddTorque(Vector3.forward * randomZTorque);```
It starts rotating from the feet, instead of from the pivot. why?

or is this a question for in #⚛️┃physics ?

[robust schooner]

never mind - didn't read whole way through

[limpid thistle]

this does fix it so the pivot is at the feet, but doesnt fix the issue that i want it to rotate from the center haha

do i have to import the meshes into blender and reset the pivot?

[robust schooner]

if you want to rotate it from a different pivot, you could parent it to an empty

then rotate the empty

[limpid thistle]

thats already what im doing, but it doesnt work

[midnight plover]

Just a little hint that you are not in pivot mode

Top left of your scene view, it says "center"

[limpid thistle]

already put it in pivot mode, doesnt fix a thing

[midnight plover]

Can you show, where your pivot mode is placing the indicators of the object you want to rotate? But yeh, might not be a code question at all

[limpid thistle]

at the feet, like i said in my post

Also tried placing the mesh location at -1, so the pivot is here, but this does not work in runtime

[midnight plover]

everything tied to bones is not just easily moved around because the bones and animator control where the mesh should go. #💻┃unity-talk might be a better place to ask, as this is not a code problem but a setup problem

[elder canyon]

If I need to add forces to my character in random directions. Should I go with Character controller and program my own force generations or scrap Character controller and go with rigidbody?

What's the best solution for a 3d character? would it be a character controller or a rigidbody?

[scarlet pasture]

        {
            Debug.Log("Ich fahre jetzt los!");
            var pos = this.transform.position.x;
            pos += Speed * Time.deltaTime;
            this.transform.position = pos; 
        }```

Hey why cant i use that?

i dont find the Problem.

[midnight plover]

Please explain a bit more, what is not working or what prevents you from using it? where are you firing this code?

[slender nymph]

You need to create a Vector3 to assign to transform.position, you can't just assign a single float to it

[limpid thistle]

var pos is now a float, not a vector 3

[limpid thistle]

for forces you should use a rigidbody, thats the easiest way to do it

[scarlet pasture]

i wantedt that the bus drives forward

[limpid thistle]

transform.position += Vector3.right * Speed * Time.deltaTime;

[elder canyon]

Easiest way, but the fps movement wont be natural as I bump into colliders right?

[limpid thistle]

That moves it on the X-axis only

[limpid thistle]

its a whole lot of tweaking, but that is what unity gives us...

[scarlet pasture]

AHHHHH i see it now, i need to give a Vector3 Position

thank u

[elder canyon]

I feel like adding custom force methods to character controller would be more natural?

[limpid thistle]

yes it is, but then you will have to create your own custom force methods, which is easier said then done

and AI is not great with making anything physics based

[elder canyon]

It's pretty easy

transform.position.x is a float, basically a real number. if you're moving it with some kind of speed, it'll be pretty hard to make it exactly -2.

if u use == it'd be super hard to hit it exactly..

like approximation

[naive pawn]

you could also define an epsilon
like Mathf.Abs(-2 - x) < 0.1f

[rocky canyon]

im sure theres cleaner ways (ie ☝️ ).. but just pointing out the difficulty of hitting a number exactly

[scarlet pasture]

            {
                Debug.Log("Hey!");
                start = false; 
            } ``` Thank u i did it like that, i saw a Code Syntax in a Forum

[rocky canyon]

may want to also include the "false" into the condition itself

tha way when it triggers it does it things and waits for something else to reset the flag..

that way ur code doesn't run it more than once at a time

[scarlet pasture]

a u mean a bool befor the Movement run, if yes i did that

[rocky canyon]

if(inRange && start)

yea

[tulip stag]

Is it a bad idea to add a listener to an event inside of the very script it is "firing" from?
I have an event that, when fired, other scripts do their things but there are some methods in this script that also always get called whenever I have to fire them. What I'm doing rn is

    MyEvent?.Invoke();
    MyMethod1();
    MyMethod2();
          (multiple times in the script)

Should I be doing

  public static Event Action MyEvent;
  OnEnable
  {
      Subscribe to that very event that is in this script => MyMethod1, MyMethod2;
  }
  OnDisable
  {
      Unsubscribe and stuff
  }

[rocky canyon]

well if its gated somewhere else thats fine too.. just saying.. cuz that condition could run alot if it isn't controlled somehow

-1.9, -1.98, -1.99, -2 <- liek that would run it 4 times (say if u only wanted it to run once when the range is detected)

[naive pawn]

both of those seem viable

[rocky canyon]

i do it all the time

[naive pawn]

consider if the MyMethod1/MyMethod2 would change over the course of runtime, if so then you'd be using events sure

[tulip stag]

For some reason my brain is telling me listeners to events in the same script are a bad idea but I can't tell exactly why

[rocky canyon]

as long as u subscribe and unsubscribe when u need to doesn't really matter if its in the same class or not

[tulip stag]

Fair enough

Thanks!

Is isGrounded is bugged for CharacterController?

[naive pawn]

no, make sure you're adding gravity even while on the ground

[elder canyon]

I feel like the only other way, I can know if the character is on the ground is by doing a ray cast

[elder canyon]

I did that

[naive pawn]

how it works is basically it checks if it hit the ground the previous Move
if it didn't move vertically, it'd basically be hovering above the ground and it'd consider that not grounded

[elder canyon]

I'm applying a slight gravity, while it is still on the ground. But It's still not working reliably

[naive pawn]

perhaps show your movement

If I do slight movement, isGrounded works. But that is not the solution

Should I just go with a linetrace system, instead of this buggy "IsGrounded" ?

@naive pawn

[naive pawn]

linetrace? do you mean raycast

[naive pawn]

you should not have multiple Move calls in a single frame

[hot wadi]

U should keep the velocity zero when it's grounded instead of negative value

        {                                                                                    
            verticalVelocity = 0f;                                                          
        } ```

[elder canyon]

But why tho?

[naive pawn]

that's how charactercontroller works/is designed

it expects 1 move call per frame

[rocky canyon]

just combine ur vectors into (1) and pass that iinto the move.

[elder canyon]

If that's the case, shoudlnt it work if I do not apply any movement? But it's still not working

[rocky canyon]

Move(finalVector * time.deltaTime);```

[elder canyon]

Oh you're right @naive pawn .
It's working now
Tnx

How did you figure this out

[naive pawn]

when you break a system's expectations, good systems will try to cope with the weird input.
sometimes they work, sometimes they don't
garbage in, garbage out

[naive pawn]

a lot of people have had the same issue

[rocky canyon]

        private void ApplyGravity()
        {
            if (characterController.isGrounded)
            {
                if (gravitySim < playerSettings.gravity)
                    gravitySim = playerSettings.gravity;
            }
            else
            {
                gravitySim += playerSettings.gravity * Time.deltaTime;
                gravitySim = Mathf.Clamp(gravitySim, playerSettings.maxFallSpeed, 0f);
            }
        }``` its common to use a *small* downward vector when grounded... (constant)
and a accumulative downward vector when in the air so u accelerate when falling

[naive pawn]

the documentation for SimpleMove also states this

It is recommended that you make only one call to Move or SimpleMove per frame.
https://docs.unity3d.com/ScriptReference/CharacterController.SimpleMove.html

not sure why that isn't in the docs for Move as well

[rocky canyon]

i think thats the first thing i learned ^ bout 4 years ago

            finalVector =
                (groundVector * finalSpeed) +
                (airVector * playerSettings.airSpeed) +
                (Vector3.up * gravitySim);

            if (jump.magnitude > playerSettings.jumpMagn)
                finalVector += jump;

            characterController.Move(finalVector * Time.deltaTime);```

really helped learning Vectors as well as a byproduct

[naive pawn]

(though, since i work in 2d, i haven't used the charactercontroller myself at all. i know the 1 move per frame rule purely from helping here lmao)

[rocky canyon]

combining them.. (modifying pieces of them).. removing some of it etc

[naive pawn]

and the isGrounded thing

[rocky canyon]

lol, great thing to know 😉

[rocky canyon]

isGrounded gets complained about alot .. but for simple controllers i believe its fine..

i use it all the time (without any additional ground checks)

altho there is a bit of an issue i found. and its probably b/c of what u said earlier Chris..

I had to end up running two groundChecks.. for some reason to get my "Landed" sfx to play..

[hot wadi]

Tbf I don't see any problem if I'm just moving my character on static environment
But yeah, there should always be a gravity

[rocky canyon]

teh first one couples with the movement code.. and the last one is reassurance i guess.. (its the only way to get my Landing sound to not be sporadic and inconsistent)

[rocky canyon]

i was just pointing out that having a slightly negative force helps..

i would imagine that 0 could cause weird issues

could.. i just dont know how off-hand

[naive pawn]

it's required to make isGrounded work properly, because it's expected from the cc

[rocky canyon]

^ yea there ya go

u could be ever so slightly above the ground.. and the check would be lying

something something.. maybe skinwidth

[naive pawn]

you would be 0 units above the ground but not actually touching the ground (which gravity would make you do)

[hot wadi]

About that, I stopped using cc ground check and just go with a small offset spherecast

[rocky canyon]

totally acceptable.. ^ see thats what i meant

[naive pawn]

iirc, CC doesn't do physics-esque collision checks
it checks if the previous Move wouldve hit anything

that's why you need to move downwards to detect the ground

since if you don't move downwards you technically don't touch the ground

[rocky canyon]

i like array groundcheck w/ raycasts

can use multiple rays to get a more advanced ground-check

if these rays are grounded but these arent.. i can tell that ur standing on a ledge..

in a certain direction

same w/ slopes and whatnot

[elder canyon]

Nice! I was thinkingn about implementing slopes. Guess this way is convenient. But 4 linetraces are enough right? Why do we need 6 tho?

[rocky canyon]

u don't 4 would be plenty

or 5 if u want one in the center

📌 note: theres dozens of ways to do Ground Checks.. Raycast is just a single one..

you can do overlapspheres, checkspheres, spherecasts, boxcasts, regular trigger colliders. so on and so on

[elder canyon]

Thanks!

[sonic dome]

    void Update()
    {
        if (!IsOwner)
        {
            return;
        }

        _moveDirection = move.action.ReadValue<Vector3>();
        Debug.Log(_moveDirection);
        airDragHandler();
        sprintHandler();
    }

why is _moveDirection always 0 0 0

[naive pawn]

make sure it's enabled

also why is it a Vector3

[sonic dome]

it was working like a sec ago

[naive pawn]

oh i guess vertical movement, huh

[cosmic dagger]

You need to check move or move.action . . .

[naive pawn]

check the input debugger to make sure input is being recieved

[sonic dome]

i did set all that up

[sonic dome]

hows that done?

[naive pawn]

ohhhh no swizzling

[naive pawn]

open the input debugger from window > input system > debugger, or something along those lines

[sonic dome]

where is input system

[naive pawn]

in general, perhaps?

[sonic dome]

nop[e

[naive pawn]

oh, in analysis, apparently

...you couldn't just look through each category? lol

[sonic dome]

yea found it

[sonic dome]

sry my bad im cooked

[naive pawn]

that's not what i'm trying to get them to look at, no

[sonic dome]

weird

[naive pawn]

so input is being received, but the action isn't forwarding it - that narrows it down a lot

make sure the action is enabled

[sonic dome]

hows that done

[naive pawn]

if the input action asset is set as the default, it'll be enabled

if not, you'll have to enable it yourself

[hot wadi]

U did not set it in OnEnable(), did u?

[haughty forge]

How to code for checkpoints and reset car if it flipped or out of the track?

[naive pawn]

those are quite a few different questions

[rocky canyon]

check them sequentially

[naive pawn]

break them down into smaller problems, and google the simpler problems to start

saving checkpoints, checking rotation, making bounds, etc

[haughty forge]

Ok

[sonic dome]

nope

but it was working perfect like an hour ago

[naive pawn]

and is it set as the default asset

[sonic dome]

😭

[sonic dome]

i refer it like

    [SerializeField]
    private InputActionReference move;

[naive pawn]

that's not what i asked, no

is the inputactionasset it's in set as the default asset for the project

[sonic dome]

it is empty rn

let me add it

[naive pawn]

you need to have the action enabled, which can be done manually, or by setting it as the default asset

[sonic dome]

it worked "_"

thanks so much

[hot wadi]

Heh

[naive pawn]

it's in the inputsystem documentation

[still ingot]

Are there any good resources for how to create a custom inspector for beginners. I have been trying but encounter odd errors each time. More noticeably when changing my script to derive from the Editor or EditorWindow i get an error?

I have even added a assembly reference to try and fix the error but no luck. What am I doing wrong?

[grand snow]

Very strange, UnityEditor.Editor is correct

[rich adder]

I think you dont even need the assembly referenced there, did you click definition on Editor class? where does it take you

btw all the editor resources are pinned in #↕️┃editor-extensions

[grand snow]

the core apis are always avaliable to all assemblies so yea not required

[still ingot]

What is the correct process to set it up. I'm really lost right now because I have been trying for a week now and doom scrolling for youtube tutorials

[rich adder]

As I said first, check the definition for Editor and see where it takes you, it could be another class maybe outside the assembly ?

[still ingot]

It takes me to the editor script but it says decompiled

[rich adder]

weird.. is the error present in Unity ?

could be VS buggin out ?

[still ingot]

I will try to regenerate the script to see if anything changes but idk

[rich adder]

if the error is a compile error it should show in unity, if its not something is wrong in VS

maybe not related or maybe it is but tbh unless you have a specific reason to use asdef I would not use it, just overcomplicates the project structure

[still ingot]

I have no errors in unity so it might just be visual studio

[rich adder]

yeah its weird maybe you can try regen project files, this is one of the reasons I stuck with VSC on windows as well, I had VS bug out like that for no dam reason

[stray fog]

Hi,
Has anyone worked extensively with KCC?

I am building a CharacterController Class, Player Class and Camera class. I am trying to build a full body controller. Basically I have gotten the movement correctly and mouse look around but the camera won't stay infront of the head, I will be implementing a IK solution for spine and head movement at later stage until I have the base fundemental of player controller working.

using UnityEngine;

public class PlayerCamera : MonoBehaviour
{
    private Transform _followTransform;
    private float _verticalAngle;
    private float _horizontalAngle;
    private Vector3 _offsetFromFollow;

    public void SetFollowTransform(Transform t)
    {
        _followTransform = t;
        // Calculate and store the initial offset from the follow transform
        _offsetFromFollow = transform.position - t.position;
    }

    public void UpdateWithInput(float deltaTime, Vector3 rotationInput)
    {
        if (_followTransform == null) return;

        _horizontalAngle += rotationInput.x;
        _verticalAngle -= rotationInput.y;
        _verticalAngle = Mathf.Clamp(_verticalAngle, -89f, 89f);

        // Apply rotation
        transform.rotation = Quaternion.Euler(_verticalAngle, _horizontalAngle, 0f);
        // Maintain initial offset from the follow transform (eye level)
        transform.position = _followTransform.position + _offsetFromFollow;
    }
}

PlayerCamera

[still ingot]

I regen the code and got these options now?

[grand snow]

Important question. Does the previous example compile successfully in unity? What happens if you write the full name inc namespace?

[rich adder]

yeah try doing : UnityEditor.Editor

[still ingot]

The build was successful I used both Editor and UnityEditor.Editor to be sure. I just selected all for my assembly reference

[rich adder]

not sure the build in VS relates to a unity project, either way it seems something is wrong between the two somehow.. not sure wht it is, have you tried without the ASMDEF ? i thought it makes a difference but worth trying

[still ingot]

Omg it was the ASMDEF the entire time haha!

[still ingot]

i just deleted it

[rich adder]

huh isnt that something... I just tried it with a test Asmdef but it worked fine

[teal ice]

I have a problem whith the player input component …
How can i fix it ?

[rich adder]

https://docs.unity3d.com/Packages/com.unity.inputsystem@1.8/manual/ProjectWideActions.html

they are recommending you make your own basically

cause the project wide conflicts with the purpose of PlayerInput

with System wide you don't need PlayerInput and vice versa

[tulip stag]

Ok so, continuing the talk from #💻┃unity-talk

        var loader = new WWW(url);
        yield return loader;
        output.text = loader.text;
    }```

This is the snippet in the package

        var outputText = "";
        for (int i = 0; i < urlArr.Length; i++) {
            var loader = new WWW(urlArr[i]);
            yield return loader;
            outputText += loader.text;
        }
        output.text = outputText;
    }```

This one too

[rocky rock]

what do people recommend using to unit test async methods?
I was using await Awaitable.NextFrameAsync() but since a recent TestRunner update, all tests using that method just stalls forever

[rich adder]

something like this basically

private IEnumerator OutputRoutine(string url)
{
    using (UnityWebRequest request = UnityWebRequest.Get(url))
    {
        yield return request.SendWebRequest();

        if (request.result != UnityWebRequest.Result.Success)
        {
            Debug.LogError(request.error);
            output.text = "Error: " + request.error;
        }
        else
        {
            output.text = request.downloadHandler.text;
        }
    }
}```

[rich adder]

https://paste.mod.gg/edkefefestvl/0
very similiar as you can see

[tulip stag]

You just fed my family for thr forseeable future

I'll call the wife, job is secured, food will be on the table tonight

[rich adder]

hehe yay my work in red cross paid off

i shouldve probably inversed and put Success as first if statements lol

oh well you can always do it that way if you want but no biggie

https://docs.unity3d.com/6000.2/Documentation/ScriptReference/Networking.UnityWebRequest.Get.html
unity uses a switch to cover more but yeah

[tender mirage]

Does anyone know how to remove a specified entry in a table?
lets say i want to loop through a table and remove that specific index if conditions are met.

if you post an answer, do only post the keyword for what i need

[grand snow]

Edit mode or play mode?

[naive pawn]

a table of what exactly? could you give some context

[rocky rock]

edit mode

switching to await Task.Delay(0); now

[grand snow]

Good lordy that's not the solution

I use unitask because it actually works in edit mode properly

[tender mirage]

i want to count children in a gameobject. but the count should exclude anything that doesnt have the tag "Target"

[rich adder]

don't add it in the first place?

pseudoish

var myList = new List<GameObject>();
foreach (var go in gameobjects){
if(go.CompareTag("myTag")) myList.Add(go);
}

[tender mirage]

i see,

i just made this myself as well. Altough i've only ever used the keyword list to grab Resource folder items.

private void UpdateTargetCount()
{
    //
    Transform[] Children = GetComponentsInChildren<Transform>();

    print(Children.Length - 1);

    TargetCount = Children.Length;

    for (int i = 0; i < Children.Length; i += 1)
    {
        if (!Children[i].CompareTag("Target"))
        {
            TargetCount -= 1;
        }
    }

    


}

[rich adder]

sketchy

if it works though you're fine.. though imo the keeping a sepeare list can come in handy if you need to do something specifically with the Targets

otherwise you need to iterate this list again and do the same thing

[tender mirage]

yeah, i have a hunch my projects other code are like that too

the only thing i'm remotely proud of is my versitile shake script

this one is especially a mes since i've been experimenting alot if certain features. honestly it's pretty bad going through it

sometimes

[rich adder]

btw you can also do

  foreach (Transform child in transform){
//stuff
        }```
<https://docs.unity3d.com/ScriptReference/Transform.html>

and skip GetComponentsInChildren

[tender mirage]

wait that works too?

That's. i don't know how to feel about it.

it seems amazing. and easy but also kinda cheesy lol.

[rich adder]

yea idk skips an extra GetComponentsInChildren prob

first time I've seeni += 1 in a for loop lol

well maybe not in a while at least

are these objects added at runtime ? you can also keep track of them when you do that.
otherwise I just use the inspector and put them in there

[naive pawn]

it also probably skips the array allocation

and uhh i think it's ordered by child order? whereas GetComponents would be ordered by internal id

[tender mirage]

i've been avoiding the inspector for awhile now. Trying to learn management

[rocky rock]

why not? despite what I'm reading, my tests are passing, so it makes me believe it actually does run async
what about Task.Yield() instead?
Also I just realized Awaitable.NextFrameAsync() only stalls in one unit module and not the other, despite being written the exact same way 🤔

[tender mirage]

although i'm definitely not so good at it 😂

[rich adder]

the inspector is most efficient way in terms of references.

its basically game* compile time dependency injection

[tender mirage]

I know, and i should definitely use anything that makes my life easier

also yeah i dont use ++1

for consistency, is that weird?

[rich adder]

if you do ++ you don't need 1

[tender mirage]

oh right.

it's ++i

in this case

[rich adder]

😢

[sick arrow]

can anyone help me with some animation riging?

[rich adder]

but yeah tomato tomato

[rich adder]

only if its a code question otherwise #🏃┃animation

[sick arrow]

thanks i was looking for that channel

[tender mirage]

💀

🤝

oh wait, it is actually i++ isn't it.

not ++i

[rich adder]

yes

[tender mirage]

yeah. i don't use ++ at all..

[rich adder]

if you did ++7 that would not make much sense

wait it works..

huh TIL

[hot wadi]

It's just the order of the calculation

[rich adder]

right..pre-increment vs post

[tender mirage]

huh.

dangit. i somehow feel like that could be something neat to use for counting.

and i don't even use the normal one.

[naive pawn]

the difference only really matters when you want to use and immediately increment or vice versa

typically with implementing lists/stacks with arrays

[rich adder]

ya in for loop they do the same thing I think ?

[tender mirage]

that can be really important tho.

i can imagine

[rough granite]

Odd...

[naive pawn]

if the value isn't used, then there's no difference, yeah

if the value isn't used they're compiled into the same thing even
optimization ftw

[grand snow]

Using Task won't reliably keep you on the main thread

[naive pawn]

(i++ is actually kinda expensive in comparison, in terms of machine cycles)

[rich adder]

yaseem so, just wanted to double check
https://dotnetfiddle.net/wYzLUi

[rough granite]

Reminds me of my java teacher that never used Value += Number; and instead always went Value = Value + Number

[tender mirage]

quick question. how long have you guys been coding?

like in general

anything counts

[rich adder]

idk 4 years maybe ?

I started whan I learned unity 😛

[rough granite]

Really? What'd be cheaper?

[tender mirage]

oh really? did you ever try something else?

or you've been commited perhaps. hehe

[naive pawn]

++i = ADD addr, imm 1
i++ = MOV addr, addr ; ADD addr, imm 1 ; MOV addr, addr

iirc. the last MOV might not be necessary

[rich adder]

a little bit of C and C++ but more recently, before that no experience except some HTML and basic JS.
I used to use Game Maker and thought coding was heard 😆

[naive pawn]

oh damn, like 5 years at this point. time really does go by...

[hot wadi]

Did u study assembly?

[rough granite]

Gamemaker code feels so yucky :/

[naive pawn]

not formally, i dabble with it a bit

[rocky rock]

I started learning to code 15 years ago

[naive pawn]

i don't really know the actual languages. i can read but not write, but i can write assembly level logic
ive made 2 cpus and working on a third in turing complete (hard recommend)

[rough granite]

Though i have the same opinion with python and whatever Godot uses

[naive pawn]

oh and ive read assembly in ctf puzzles (cybersec)

[rich adder]

yeah those pythony languages are my peeve..

[zenith cypress]

There isn't a difference in C#, but iirc there is in C++.

[naive pawn]

no, the difference is the same

[rough granite]

I need my semicolons and swiggle brackets to be happy

[hot wadi]

That's still pretty impressive. Learning how computer actually works

[naive pawn]

the differences are optimized out in both languages if the value isn't used

[tender mirage]

😂 i've seen some c++ code. What did you do with c++ then? like unreal engine? i've seen some people send code of it and it just seems like it's on a another league

[rich adder]

yeah imagine your code breaks because you didn't indent ? Im looking for whitespaces now ? fuck all that noise lol

[tender mirage]

honestly, you always sounded like some veteran that had been coding for a decade..

[naive pawn]

bro im in first year uni

[rich adder]

nah Unreal is too much for me..
mainly doing Embedded system / chips like esp32 nd so on
a little some basic openGL apps to learn some frameworks

[tender mirage]

💀

[rough granite]

Unc

[tender mirage]

yeah, sorry for the assumption

[tender mirage]

good.. yeah i know what you mean.

it's like using blender..

but its a game engine

[rich adder]

there is just so much C++ boiler (in Unreal) you have to write for simple systems that Im just like "yeah I can do this in c# in a few minutes..." I'm not enticed to use unreal much if I can do the same things in Unity but quicker

[tender mirage]

so it's like a easier assembly i take it?

[rich adder]

I enjoy doing unreal for cinematics and video work

[tender mirage]

i' was modding with some unreal uassets, it's very interesting how the reverse engineering works with that engine

[rich adder]

maybe because I also don't know C++ that well so their engine seemed very opinionated so I gave up on it and use blueprints

[tender mirage]

that's the visual coding thing right?

[rich adder]

yeah

[tender mirage]

even that seems not so fun

lol

[rich adder]

creeping into offtopic here 😅
but yea it gets messy quick and at times you really do tell yourself "I can do this In code soo much quicker (in Unity) " But if I work with someone else I muster through

[rough granite]

Visual coding feels quite degrading if you already know code (at least imo)

[rich adder]

In Unity/Unreal seems good when working with designers though, instead of doing like 50 custom tools in code 😛

[rough granite]

Yeah that's fair i would die if i had to learn shader code instead of have access to the visual shader graph

[zenith cypress]

Hm currently messing with it in SharpLab (for C# tests) and not sure what you mean. Loops end up the same thing, and usage without a loop still gives basically the same instructions (it just flips an instruction order). Got an example of what you mean?

[tender mirage]

indeed. on that topic how do you feel about the unity's animator thing, i think that also was a form of visual coding?

[rich adder]

yeah shadergraph really does open a lot of awesome possibilities when having no shader background.. have you tried VFX graph ? I saw some really cool stuff you can do there

[naive pawn]

int a = ++b;

[rough granite]

I've looked at it 3 times and gave up cause it never worked right

[naive pawn]

it makes a difference if you actually take the result of the operation

[rich adder]

the StateMachineBehavior can come in quite handy at times

[zenith cypress]

Yeah that's my second test and it's the same instructions, just a part is swapped

[rough granite]

I have and made quite a few effects for my game, pushed a release and got feedback about how it would crash users computer, which i found kinda odd cause my own pc isnt even that good yet it ran faster than particles systems

[naive pawn]

my main point being that there's a difference, yes

[rich adder]

with VFX graph or particle system ?
I know VFX graph is way better cause it runs on GPU instead of CPU

[thorn holly]

is it bad practice to use the legacy and modern version of the animator at the same time? I usually use the modern one but theres one specific thing here where it would be very helpful to create an animation at runtime, which it seems the modern version cant do

[rich adder]

#💻┃unity-talk

wdyn "Legacy Animator"
are you confusing it with Animation component ?

[tender mirage]

Seems like a hassle to. better sticking with coding and sharping that area

while you're at it

[naive pawn]

oh i wasn't clear with what i said earlier
the machine cycles part was about c++, machine cycles are kinda negligible with interpreted languages aren't they

[rough granite]

Used particle system before switched to vfx graph, vfx graph crashed their game particle system didn't

[zenith cypress]

Yeah (in C# at least)

ldloc.0
dup
ldc.i4.1
add
stloc.0

vs

ldloc.0
ldc.i4.1
add
dup
stloc.0

(just throwing out the list for ref)

[thorn holly]

yeah but the animation component is legacy

[rough granite]

Which is why i found it so odd that it would crash them

[rich adder]

mhm maybe their GPU was not good at all

[thorn holly]

so is it bad practice to use the animation component while using the mecanim animation system?

[rich adder]

yeah No reason to use Animation imo if you're using Animator

[rough granite]

Maybe but even my gtx 1080 had the fps rise like 30 from it

[zenith cypress]

No il colors, so had to use cs colors

[thorn holly]

but there is i want to create and play an animation clip at runtiime

thru scripting

hence i asked here instead of unity talk

[rich adder]

yeah the GPU can compute faster in some cases, especially graphical stuff like that

[naive pawn]

source code:

void w() {
    int a = 0;
    a++;
}
void x() {
    int a = 0;
    ++a;

    int a = 0;
    int b = ++a;

[rich adder]

at the cost of your particles cannot interact with physics objects like PS can

[rich adder]

I dont see how you cant just do the same with Animator though

[rough granite]

If only computer cpus could easily talk to each other, wonder wht intel makes these 24 core cpus when most apps cant even use 3/4 of them

[naive pawn]

a single asm instruction is 4 il instructions lmao

[rough granite]

So whats the fastest of these 4 tests?

[rich adder]

to be fair its usually APP makers that make them perform better with single cores, its an old school mentality ig

[naive pawn]

i mean if you actually optimize they're all 0ns because they're all optimized into nothing

also, speed was not the goal in any way

this was a comparison of the work done

[thorn holly]

ok i googled it and i can do so by creating an animation override controller at runtime and then assigning it the animation

i think thatll work

thanks

[rough granite]

Fair was just curious if there would be any effect in a huge loop

[naive pawn]

the overhead is tiny

whatever's in the loop far outshadows the increment

[rough granite]

Yeah fair point damn Vectors taking ~700ms for 1.2 million calls

[haughty forge]

I'm so bad at Unity, how to code?

[rich adder]

[haughty forge]

Sigh

[haughty forge]

It's boring of watching at 20 minutes video

[rough granite]

Bruh really should alt f4 then

[rich adder]

if you find it boring to learn new skill then what are you even doing then

[zenith cypress]

Gotta get through the boring to get to the good stuff

[haughty forge]

I was just having dream about making my racing game

[rough granite]

Watched a code monkey short video the other day where he brought how people complained that 3 hour simple game making videos weren't simple cause they were too long, could see this guy being one.

[rich adder]

programming a game isnt something you learn overnight. there is tons of material you need to learn

[haughty forge]

Fine

[rich adder]

its true though... I find those very long videos are not very good

[haughty forge]

First of all, i'm trying to avoid copyrighted codes

And idk what to do

[rich adder]

copyrighted codes?

[rich adder]

hes probably one of the worst examples tbh..
he claims "clean code" but a lot of his shit is cringe at best, and not clean code

[haughty forge]

Yes, the scripts is also copyrighted

[rich adder]

what scrips are you talking about? nothing you will learn will be copyrighted

[edgy sinew]

CodeMonkey doesnt give a sh** at all, bad resource 100%

90% of Unity videos are doing WrongLerp so ...

[rich adder]

yet he's popular 🤷‍♂️ so must be doing something right

[rough granite]

I dont disagree lol (nor do i really watch much of his stuff, like 1 video every 5 months) but it's true that there are people saying that a 3 hour video on making a whole game is too much when most games take months to years to make anything remotely meaningful

[edgy sinew]

I think it's the thumbnails, he uses Synty assets and others

Because of the results people think, wow that looks pretty good!

[rich adder]

who knows.. I just know that unity using his shit on their site is ultimate cringe

[edgy sinew]

Manager's choice (person who does not know how to code) type shi

[zenith cypress]

Go in for the concepts, not for the copy/paste

[edgy sinew]

Same reason AI generated code gets approved in PRs

[naive pawn]

let's say you have a loop adding 2 10-element arrays of vector3's memberwise
3 instr are for the for initialization
6 instr per loop plus the end, so 65 instr are for the inc and cond
so overall 68 instr of overhead on the for

meanwhile the actual work, 10+28 per loop, so 380 instr for the work

would be more with a list, since there's also the overhead with calling each method too

[rich adder]

yeah thats how I extract info from most resources, I never copy . His shit is like brackys tho, beginners mistake it for actual "good code" and end up writing these very over convoluted systems lol

I mean on one of this video he really claim doing transform.Find("TheThing") was "good code" lol

[rough granite]

And i assume this ratio of instr for the for loop and the work would drastically grow as the loop gets bigger say 50 10-element arrays. So as you said yeah i guess worrying about the i++ is meaningless for a loop

[naive pawn]

and this is a very simple loop with minimal work too

[grand snow]

I feel like worrying about i++ or ++i is silly as we can probably trust the compiler to optimise this based on usage

[rich adder]

I opened a whole can of worms 🥹

[grave bluff]

which is the opposite of what I learned in my first c++ class where they insisted we use ++i

idk what to believe anymore

[zenith cypress]

they also insist you use C++, so can you really trust them

[rich adder]

wait..isn't C++ just D 🤔

[grave bluff]

no that's C##

[rich adder]

I call it Bflat but ## would be B?

[grand snow]

unless you are using some ancient compiler i doubt it will struggle with such an easy optimisation

godbolt can show you anyway what it will do

https://godbolt.org/

[edgy sinew]

⭐ hi guys, is it computationally expensive to be passing around parameters like this all the time? This is a static Spring class based on Ryan Juckett's work.

I'm considering to make it non-static and just have an instance wherever I need a Spring. So the values are just there in the instance, not always being passed into functions.

        ref tDampedSpringMotionParams   pOutParams,       // motion parameters result
        float                            deltaTime,        // time step to advance
        float                            angularFrequency, // angular frequency of motion
        float                            dampingRatio,
        ref float                           pPos,           // position value to update
        ref float                           pVel,           // velocity value to update
        float                               equilibriumPos, // position to approach
        in tDampedSpringMotionParams        springParams)```

[grand snow]

most here is stack allocated so no

best place for variables to be!

[rich adder]

value types woo

[edgy sinew]

I see. You really think I wouldn't gain any performance by having instances with member variables instead?

It seems so strange to be passing around 8 variables all the time.

[grand snow]

when all the needed variables are all together (such as in the stack) then thats the best case

(we know here most of these arguments will be because they are value types)

the ref float args im not sure, depends on where they are from

[edgy sinew]

I have 1 more question.
If I have some function, is it worthwhile to check if it needs to be called before calling it? Or is it equivalent to check within the function itself and exit if no action needed?

[grand snow]

Lots of args and called a lot? better to avoid the call early

[edgy sinew]

So for example with the code I sent.

// Option 1 check before call function
if (currentPosition != desiredPosition)
    UpdateSpringStuff( parameters)

// Option 2 check inside of function
UpdateSpringStuff( parameters) {
    if(currentPosition == desiredPosition)
        return;
    ...
}

Option 1 is better because we avoid having to pass in those 8 arguments right? And the function call overall

Kinda feels like I just answered my own question 🤔

In-function "check if any action needed" is so much cleaner and self-contained but. Yeah passing parameters around for nothing just sounds wasteful

I suppose with an instanced class it's possible to avoid the function call and self-contain the check. Idk. That's why I didn't want to use a static class

For something that will be around for the entire game/scene, why would I keep it static? Rather keep all the stuff together in an instance of the utility.

[polar dust]

Generally you should return inside a method when it's unable to continue what it's doing. Maybe it creates list, checks the list, and returns early if that list had more than 5 items.
Only that method had any knowledge of the list inside of it, only the method can return.

As for checking before calling it, simplest would be if it's a method to capitalise a string. If the string is empty, you know there's no point calling the method in the first place

[naive pawn]

aren't they copied around because they're value types though

[edgy sinew]

Excluding ref

[naive pawn]

well.. reference types would also be copied around

[edgy sinew]

I thought ref just passes a reference (location in memory)

[naive pawn]

the ref... i guess that would also be "copied"?

[naive pawn]

it's all just passing a word to the function

[edgy sinew]

Objects are always passed by ref, too, I think

Value types are copied, i think there's exceptions with that too

[naive pawn]

a ref is just a 64 bit integer that represents an address
a float is just a 32 bit integer that represents a real number

both cases they'd be copied

wouldn't the "bad" case be with copying a large value type?

[edgy sinew]

I'm thinking, to keep the functionality and the variables all together and just have instances. So, the instance itself can decide whether any work is needed, BEFORE it passes 8+ parameters all over the place.

[naive pawn]

though, it's still a limited amount of copies, so probably not an issue either

[edgy sinew]

Well I suppose pass by value can be faster than.

But it creates a copy of it, so ... Idk

[naive pawn]

probably not

to my understanding, passing arguments inherently does copying
how much is copied depends on the types

[edgy sinew]

To conclude - the point here being I don't have to keep writing if (springDesiredPosition != springCurrentPosition) every time I need a Spring.

[naive pawn]

here it's 4 refs (64 bit each) and 4 value types (32 bit each)

i will have to stop myself there because i am now realizing that this is most definitely micro-optimization and absolutely does not matter

design it in a way that makes sense and is easy to use, don't worry about the perf

[edgy sinew]

I used to have 550 FPS now i have like 300-400

I can't keep losing FPS so I need to know these details

Thanks guys for the knowledge

[naive pawn]

it's not because of your arguments, it's more likely due to the actual work being done

to put this into perspective:
the thing you're worrying about, is going to be like 0.5% of the work your cpu does.
optimizing it won't get you anywhere

[polar dust]

You can worry about it when that 300fps turns into 3fps

[edgy sinew]

I've still got tons of game to build so. I need every frame

[polar dust]

well, "when" is a little mean 😆

[edgy sinew]

on my cheaper machine, I'm only at 180 FPS. Used to be 280

The triple raycasts probably contribute

But this spring related stuff dropped it further

[naive pawn]

don't worry about perf until it actually becomes an issue

and when it does, don't worry about these random things. use the profiler to see what's the actual cause

[grand snow]

Hey yes but copied into the new stack frame all next to each other which brings benefits compared to a ptr to the heap being copied

[naive pawn]

otherwise you end up spending 50 minutes for an extra +0.05 fps for something that was already very optimized

[edgy sinew]

I don't need the profiler, I'm looking to write tight and minimalist code.

[naive pawn]

you most definitely need the profiler if you want to actually make meaningful optimizations

[edgy sinew]

I'll let you know if I need it

For now I've just been cleaning my code and gaining FPS

Except for this Spring crap, passing 8 params around every frame. Nuts

[naive pawn]

yeah the 8 params are not the cause, man

[edgy sinew]

Will try now

[polar dust]

Performance of a build is different to performance while in the editor. If it's running well in the editor, just assume it'll run fine in a build.

When the time comes to actually making the build perform well, that's ultimately a future you problem which doesn't exist atm

[naive pawn]

cool, sounds like you found heavily unoptimized code and optimized the work

[polar dust]

Debug.Log impacts performance, too many of those can tank the framerate (don't not use it because of that)

[naive pawn]

if you don't have any more obvious stuff (no, 8 params is not "obvious unoptimized code") then you will need to use the profiler to see what's actually going on instead of guessing

[edgy sinew]

Found?

Bold accusation bro

The Spring code, yes. It's from Ryan Juckett i said that

[naive pawn]

that's literally what you said you did

i'm referring to this part

For now I've just been cleaning my code and gaining FPS

[edgy sinew]

My bad. I thought you meant my entire code

[naive pawn]

i'm saying you found patches of unoptimized code within your codebase and fixed them

[edgy sinew]

Ohh gosh my bad dude. I'm feeling attacked rn taht's all

[edgy sinew]

... They are though ... Just checked before-function-call and the framerate doesn't dip to 240 anymore

[naive pawn]

checked... what exactly?

[edgy sinew]

Tried these two options

[thorn holly]

Don’t worry about ur fps too much lol it’s going to naturally decline as you make stuff

I put in a tile system and my game dropped from 900 to 200

lol

[naive pawn]

so you're doing different amounts of work

it's the functions themselves

[edgy sinew]

yes

[naive pawn]

not passing the params

[edgy sinew]

I see. Okay

[naive pawn]

void X() {
  for (int i = 0; i < 1000000; i++) {}
}

void A() {
  if (Random.value < 0.5) X();
}

void B() {
  X();
  if (Random.value < 0.5) return;
}

[edgy sinew]

Got a lot of if (function call required) call function() to do 🥲

[naive pawn]

like, you didn't change the amount of parameters between these 2 cases, so even if the issue was in the params, you wouldn't be able to tell lmao

[rich adder]

Unity tilesystem is pretty good you tried that? it doesnt treat each tile a single gameobject so it helps a bit with optmization

[edgy sinew]

Fair, it raised concern because of how many params

[naive pawn]

tip: guard clauses!

they can clean up a lot of logic if used properly

[edgy sinew]

I never call a function with params, I just use instance variables always

What?

You mean checking in-function?

[thorn holly]

R u talking to me or vengeful

[naive pawn]

// normal conditional
if (x) DoY();

// guard clause
if (!x) return;
DoY();

[edgy sinew]

Okay so... This

[naive pawn]

helps if x is an exception rather than a requirement, it makes it easier to read

[naive pawn]

no, these 2 have the same behavior

x is checked before calling DoY there in both cases

it's just a styling thing that can make it easier to read when applied correctly

[edgy sinew]

Ah ok, that's what they call it huh.

[glass summit]

could someone explain why is this an error?

[edgy sinew]

In an Update loop with many function calls, can't just return so.

Maybe if they were all separate but anyway.

[rich adder]

you said "tilesystem" no ?

[rich adder]

read the error what does it say

[edgy sinew]

extra ) by canFire
(sorry nav yes he should learn on his own)

[thorn holly]

Uh yeah I’m just confused cause u said to put in a tile system and I already did that

Oh you mean unitys built in one?

[rich adder]

yea

[thorn holly]

I used unitys yeah

[rich adder]

ohhh ok

[glass summit]

dw i didn't understand it

[edgy sinew]

if(canFire) == true)```

2nd one is no good eh? Unnecessary ) close

[rich adder]

because you closed statement early for it == true doesnt make sense

[naive pawn]

not quite

[rich adder]

btw you can omit == true anyway..

if(canFire) works exactly the same

[thorn holly]

Oh whoops didn’t see they posted code above

[rich adder]

i thinks you wanted to do if(canFire) { //stuff so adding == true after a closed statement confused it 😛

[edgy sinew]

instanced class that has all the data available at any time > passing data around to static functions every frame 🤷‍♂️

[thorn holly]

My programming teacher taught us to say (bool == true) instead of (bool) and I nearly lost it lol

[hot wadi]

I guess it’s way more obvious that way in the beginning. U get to know better the longer u code

My teacher technically said “make me a game in C++” for the mid-term

[still ingot]

I keep on getting an error when I try to add my array to my custom editor?

            if (dialogueSettingGroup)
            {
                EditorGUILayout.PropertyField(dialogueText);
                EditorGUILayout.PropertyField(dialogueArray);
            }
            EditorGUILayout.EndFoldoutHeaderGroup();```

[rich adder]

its good to be explicit some times but its preference
mainly for == false

cause (! myBool) can be less legible/clear to some than (myBool == false)

[grand snow]

I basically never see explicit boolean comparisons apart from beginner code

once you understand that the bool itself is sufficient then you can stop

[odd radish]

Hey guys, I'm trying to make a procedural generated hospital with basic modular assets, a plain wall, wall with door and wall with window (1m x 3m). I also have a floor that works as a ceiling at the same time (1m x 1m). I want to create a script that will procedurally generate a building out of these assets with following room groups:
Corridor (A main corridor connecting one or two other corridors for example 12m long, that also can attach the two other groups of rooms)
A "patient" room (2 types: 8m x 4m and 3m x 4m)
A "examination" room (4m x 4m, spawns less then the patient room)
All these rooms need to contain different assets, but that will be added later.

Anyone knows where I can find a good tutorial about this or paper to read on? Or anyone who can help me on my way on how I should start with this?

[rich adder]

break down your issue into a more generic thing you will find it easier

there are a couple of procedural algorithms you can use BFS etc.

the rooms themselves are easy to randomize tho, you can have different prefabs that spawn in random, the room with different layouts

maybe even easier to use "snap points" at the door of each part then use some pathing algo to connect them doing some physics overlaps (a bit more brute force but works)

@odd radish http://pcg.wikidot.com/category-pcg-algorithms this site helped me greatly when I did a few procedual things

[dark laurel]

I can't recall why this is, but I have a canvas and canvas scaler, and whenever I recompile it defaults to portrait - if I change tabs to game mode then back, it resizes properly. What the heck am I forgetting?

[edgy sinew]

You were right. I switched to using a SpringInstance, no more passing parameters to static functions - no performance gain.

I did gain the convenience of all my data being within the class instance though. So I can add a new Spring with only 5 lines of code rather than 10+ and no if statements (the instance checks before it does any work.)

[grand snow]

It often does this if the game tab has not tried to render yet in editor

Probably why it fixed itself when you went to the game window

[dark laurel]

I've fixed this in projects in the past though.. but forgot how. It's kinda driving me batty

It's such a minor annoyance :p

[hallow acorn]

can triple nested for loops themselves cause performance issues? its probably mostly their content right?

[dark laurel]

yes, depends on how often you call them and how many elements they have

[rich adder]

no, and yes

triple nested loops are very important at times

[dark laurel]

for (int i = 0; i < 1; i++) for (int j = 0; j < 1; j++) for (int k = 0; k < 1; k++) // 1 operation
for (int i = 0; i < 1000; i++) for (int j = 0; j < 1000; j++) for (int k = 0; k < 1000; k++) // 1b operations

[rich adder]

especially working with multidemensional arrays

[hallow acorn]

each going from 0 to 32 and they are called once per second. there are multiple instances though but the have ann offset at which they are called

[hallow acorn]

okay thanks

[edgy sinew]

What about when it's unnecessary? Is it eating performance - having that nested branching?

[dark laurel]

depends on what you're doing in the bottom, if it's just math then it's probably pretty fast

[rich adder]

its more about what operations you are doing

[edgy sinew]

I read somewhere to avoid code branching - and try to use Math as much as possible.

[dark laurel]

32k operations per frame is trivial for x ++ and game killing if it's something else

[edgy sinew]

Like Lerp between 2 different "modes" of camera follow for example, rather than if (camFollowMode == ...)

I'm not sure which is more expensive.

[rich adder]

cinemachine 😿

[edgy sinew]

Love Cinemachine. I only use Hard Look At Target though.

Don't like their 3 ring orbit crap. Deoccluder is great

[rich adder]

ohh you're missing some really cool shit, cinemachine can do wayyy more

[edgy sinew]

🤷‍♂️

[dark laurel]

again, it's a matter of scale.. if eat a grain of rice 32k times per day, you'll live.. if you eat a chicken nugget.....

[edgy sinew]

Mostly what I've avoided is the built-in aiming, the "offset", and the orbit rig thing

[hallow acorn]

ive noticed that updating every chunk of my terrain algorithm once per second increases my frame time from 3 to 700ms which isnt good im pretty sure. im looking through my code rn and looking at every line and trying to find my massive performance loss. probably the best way would be to rewrite my algorithm as a compute shader

[edgy sinew]

Can't say I have any complaints. Unity's built in stuff is just ... Code anyway, so

Excluding complex stuff that uses Jobs like IK, I found writing my own implementations is just better

"better" in a "i can get the exact result i want" way

[rich adder]

yeah if its tailored to your need ofc.. I just trust engineers that know way more than me making all the solid implementations , Cinemachine is one of them

the damping alone takes away so much bs with doing custom Tween

dont even get me started on Blends without cinemachine

[edgy sinew]

Really? I hated how the damping felt

I use my own camera smooth following code

Vector3.SmoothDamp didn't give me the customization that using Curves did, so. I even avoided that

[rich adder]

You gotta tune a bit but eventually you get really nice cameras, depends on your needs. I mostly use it for cinematics and their awesome spline / tracking

oh and the camera shakes makes things really nice.. Recoil, Hand-Held feel all that crap you have spend time making Algortihms for noise.. in CM is just 1 component , dont even get me started on the Obstacle Avoidance (basically its just a bunch of physics queries xD)

[edgy sinew]

It can do recoil?

I've seen so many bad tutorials on IK (procedural) recoil.

[hallow acorn]

should i set my terrain chunk to static if its mesh can change/update?

[rich adder]

yeah because the impulse noise you can add it in a specific pattern or do randomized

[edgy sinew]

Bout to try right now. thank you

[rich adder]

if you want specific/predictable patterns per weapon, ala Counter-Strike and such.. Check out TheKiwiCoder he has some on that (maybe there are newer ones but he had them when i was looking into it years ago)

https://www.youtube.com/watch?v=JD7iDleSzDA

[edgy sinew]

Ohh ok. So it is Override Transform

But the camera shake is from Cinemachine

[rich adder]

yeah it just basically moves the transform for you

so you can basically make your own patterns with ease

[hallow acorn]

can someone help me optimize my code? i get like a solid .4 fps

i dont think thats really great

[edgy sinew]

yeah.. sure what you got going on

[rich adder]

how do you know its the code ? have you used the profiler

[hallow acorn]

profiler?

[rich adder]

thats the first step

it will tell you everything about whats happening

[hallow acorn]

but its def. the code thats for sure

[edgy sinew]

.4fps is wild bro, let's start with what u got going on

500 Rigidbodies colliding?

[hallow acorn]

got a single one

[rich adder]

confirm assumptions with facts. Also deep profiling will tell you which function is costing most

[edgy sinew]

how much code is there total happening at runtime?

[hallow acorn]

but my terrain is really expensive i fear

[edgy sinew]

So if you remove terrain and run around on a flat Plane, what's the FPS?

[rich adder]

you'd be surprised some times, for me it was always some URP thing or PostProcessing in the graphics

my code was doing 1kb at most

[hallow acorn]

its the function updating it once a second. without it i get 300fps with ease with 50 instances of it

[edgy sinew]

Updating what once a second? The terrain?

[hallow acorn]

yes

i already split it up in smaller chunks tho

dont want to get .1fps haha...

https://paste.ofcode.org/377XKzxMAnwRpDsLU7rnqgR thats the code

i feel like marching cubes is quite expensive

[edgy sinew]

Well. That's a lot of code.

[hallow acorn]

SetHeights() shouldnt be a problem. SetMesh() and MarchCubes() might be the cause tough

[hallow acorn]

i dont really know what most of this means but it does look horific

[rich adder]

thats why we learn the tools , so we can learn how to use them and make them less intimidating 🙂
also you want to check out the "hierarchy" mode too. Both have their uses

and "Deep Profile" to see code

though its recommended you do these in a build because in editor there is still some overhead to keep in mind

[hallow acorn]

i think thats not my biggest problem sadly 🥲

[rich adder]

mhm try heirarchy, a lot of it also seems to come from rendering / physics too 🤔

[hallow acorn]

wait a sec i think my unity is dying right now

[shell sorrel]

look at your gc allocations as well in the heirarchy

[hallow acorn]

bro these are a lot of kb i dont like this

unity uses 97%of my 32gb ram btw

wait

thats 35gb

[shell sorrel]

you using deep profiling?

if so yeah it needs a crap ton of ram

best to figure out what you need to deep profile first and run it as little as possible to get the info you need

[hallow acorn]

my spotify crashed because of it

[rich adder]

did you put an infinite loop lol

[shell sorrel]

even know i mostly develop from my laptop, i will often deep profile builds from my desktop since the laptop only has 48gb ram

[rich adder]

how you eating so much ram

[hallow acorn]

i created a blackhole probably

[shell sorrel]

am assuming the ran deep profiler o nthe editor for a decent amount of time

[rich adder]

sounds like it lol I run like 7 instances of unity and one uses 5 max

[shell sorrel]

its usage gets high quick

[rich adder]

oh yeah possibly the profiler

but code that probably creating trash sounds likely too

[hallow acorn]

my editor is still frozen its been 10 minutes now

[shell sorrel]

i would not use deep profiling till you narrow down where it should be used

also would profile builds not editor

[hallow acorn]

common bro .4 fps is insanely bad but not THAT bad

[rich adder]

though for me deep profiling was useful narrow specific function

[shell sorrel]

the spikes in your graph above look like garbage collection to me, so good chance you are making alot of allocations per frame

[hallow acorn]

yeah i think so

[rich adder]

I hate that they made Rendering and Garbage so close in color...

I always mistake them

[shell sorrel]

i can never tell the difference

[rich adder]

bruh couldnt picked a purple or some shit

[shell sorrel]

but its easy to confirm in the hieharhcy view

[rich adder]

true

[shell sorrel]

if you sort by gc allocs

but also consistient spikes like that often just mean you are allocating too much a frame

[hallow acorn]

rendering shouldnt be that expensive im rendering on a low resolution and i dont have any expensive shaders or post processing

[rich adder]

yeah the frequent cleanup will def slow your shit up

[hallow acorn]

i think it killed my shit on the spot

[shell sorrel]

there is almost always a way to not allocate per frame

[hallow acorn]

should i just terminate unity and restart it? code is saved and didnt make to many changes. its been frozen for 17 minutes now

[rich adder]

probably a good idea to conclude you made sludge and should end it

[shell sorrel]

i would

[rich adder]

corporate hate this one simple trick

[shell sorrel]

if you need to force quite and things are unstable afterwards. just close unity and delete your projects library folder and let it reimport it all

[rich adder]

refresh that cache baby!

you probably got like 20gb in there 😆

[hallow acorn]

what should i delete??

[rich adder]

the Library folder

MyProject/Library/

[hallow acorn]

ahhh okokok thanks

[shell sorrel]

while unity is closed

[hallow acorn]

its not even that bad just 1.7gb

[rich adder]

it could still be full of bad cache

Hello there,
I have a "vehicle type 1", I want to be able to switch to "vehicle type 2" mid game.
what do you suggest the best way to do that?
Like I have other scripts like camera follow script that requires the transform component of the player vehicle.
and vehicle type 1 type 2 are different from eachother so I prefer not to combine them into a single gameobject.

I tried making a vehicle manger gameobject that can switch, it worked but the issue is the current vehicle transform data when I try to access it from the scripts like the camera for example.

[rich adder]

if its gone Unity regenerates this when you open a project

[hallow acorn]

cant delete it it says files in there are open but i have unity and even vs code closed

[rich adder]

make a Cinemachine camera per vehicle, use something like Cinemachine Brain to just change between the two, remove belnding if you dont need it . Each camera has their own follow target so no conflicts

[rich adder]

restart the pc first then you have something lingering somehow

[edgy sinew]

Do you mean replace the exact object - like a character select?

[tidal lily]

issue is it's not just camera other scripts, I don't want to re-write other stuff
Like I thought about making player proxy transform gameobject but I figured it could cause issues later on.

[tidal lily]

yeah

[hallow acorn]

wait now it works

[edgy sinew]

Or fully switch to a different object - different location on the map etc

[edgy sinew]

I'd go with activate / deactivate GameObject ...

[rich adder]

you dont have to rewrite anything, dont they both use the same controller ?
