If i have a 3x3 grid of dots and want to make it so you can click on 1 dot and then draw a line between that to the next dot. But also have the program recognize what lines have been drawn so you can see if they have drawn a triangle What would be the easiest way to do that?

[eternal needle]

what have you tried so far? it should be pretty straightforward if you're storing the lines and their start or end positions in the grid

[fiery plume]

I have a button Setup for each poin and when pressed it stores a number of 1st point and when clicked on the 2nd it stores the number of second point. This way i store them like Vectors and in the end it checks for what vectors are stored to establish a shape but it seems very over complicated

[eternal needle]

when the user creates a line, you should just need to check if your start/end points overlap with another line. See if that forms a connection of 3 lines that comes back to the starting point

[queen adder]

Sorry to be here YET AGAIN but I still am not figuring out my issue (fixed parts, new errors) so this time I just took a video, I have also been looking up information and trying hard to understand it myself but my confusion comes from I thought I DID assign the game objects as shown in video, I assigned them on the GameManager script inspector.

I can also provide my code if the problem is actually there

sorry for what I am sure is massive beginners issue and for still not figuring it out even when given advice. I really have been trying to follow it I am not sure what I am doing wrong

[eternal needle]

yea show the !code. also turn off collapse in the console/make sure the errors are cleared before running it again

[wintry quarry]

This is from your video

[languid spire]

Unassigned references

[wintry quarry]

Is there a reason that, for example, the "Barrel" GameObject has the "GameManager" script on it?

THat seems wrong

you seem to have attached the GameManager script to several objects in the scene

typically a GameManager is a singleton - i.e. only one in the scene

[queen adder]

Alright so that shouldn’t be in the inspector on the side of the other objects?

[wintry quarry]

If it's in the inspector, it means you attached it to that object

So you really need to think about which object(s) this script should actually be attached to

and only attach it where it should be attached

[queen adder]

So just the GameManager object I made then?

[wintry quarry]

As for the error itself, it's pretty clear

[wintry quarry]

almost certainly..

[eternal needle]

ah yes i just noticed as well, when you are clicking those errors its highlighting the actual objects that contain the script as well.

[wintry quarry]

why would you attach it to other things?

[queen adder]

New, this is just for an assignment and they completely skipped certain info like how to make the game manager object so I thought I had to connect it for it to use the script. Very silly newbie error I see

“Connect it” but now I know I was just adding multiple instances of it

So thank you

[rough venture]

Hi! I'm making a PlayerController, but I have noticed some weird behavior. Whenever I hold down both 'w' and 's' it doesn't move (and it shouldn't). The same is true for 'a' and 'd'. But if I am holding down 'a' and 'd' and then hold down fx. 's' which moves it backwards, and then afterwards also hold down 'w' it doesn't stop moving. It still moves backwards. Why is this? Is it a bug in 2022.3.24f1? Or have I missed something?

    private void Update()
    {
        Vector2 input = Vector2.zero;
        if (Input.GetKey(KeyCode.W))
        {
            // Move up
            input += new Vector2(0, 1);
            Debug.Log("up");
        }
        if (Input.GetKey(KeyCode.A)) 
        {
            // Move left
            input += new Vector2(-1, 0);
        }
        if (Input.GetKey(KeyCode.S))
        {
            // Move down
            input += new Vector2(0, -1);
            Debug.Log("down");
        }
        if (Input.GetKey(KeyCode.D))
        {
            // Move right
            input += new Vector2(1, 0);
        }

        // Vector2(x, y)
        // Vector3(x, y, 0)

        
        //Debug.Log(input);

        transform.Translate(new Vector3(input.x, 0, input.y) * moveSpeed * Time.deltaTime);
    }```

[teal viper]

Go through your code line by line as if you're executing it with the conditions that you mentioned. What value would input have?

Ah, maybe I misunderstood what you mean.

[rough venture]

Thank you for your answer. I have just tried that, but I still don't understand what the issue is. It works when I'm not holding down 'a' and 'd'

[teal viper]

In the end you press all the keys and it still moves?

[rough venture]

Yes

If I press 'a' and 'd' before 's' or 'w'

[teal viper]

Ok. Start with debugging what's going on. Debug the pressed keys.

[rough venture]

Alright. The if statement that checks 's' is not executed when 'w' + ('a' or 'd') is pressed and vice versa

[fickle wagon]

Is it possible to return multiple values like int and string from one function?

[woven crater]

i freezed the y axis but the bullet move downward

[teal viper]

There's a chance that your hardware or os is limiting the number of processed keys at once.

[rough venture]

You can make a "helper class" that contains multiple values, and then return the class

[rough venture]

Wow, okay

[teal viper]

Try doing the same thing in a notepad and see if all 4 are printed.

[rough venture]

In a notepad it spams the last key that I pressed

I'm trying to think of a game where I can test it

[languid spire]

yes, use a tuple

[rough venture]

It might be my PC. In the other game I tried, it works the same ;(

Thank you though 🙏

[teal viper]

Maybe you just have a shitty keyboard.

[wary gale]

Hi there, am i correct that gameobject are positioned in reference to the center of the screen but mouse positions are based on the lower left corner of the game screen?

[teal viper]

That's typically the limiting factor

[rough venture]

Thank you. I am on a laptop with a built-in keyboard, so probably. I'll try it with another keyboard

[teal viper]

gameobjcts are positioned in reference to the scene origin. Nothing to do with the screen.

In 2d games it might happen to be the same point if you position your camera in a certain way

[wary gale]

Hmm okay, im guessing you can change the scene origin point?

[teal viper]

No. Scene origin point is at 0,0,0. You can change your objects relative to it of course.

[wary gale]

Oof okay. Guesd that makes things more complicated. Im trying to get the angle of my player characters "eyes" and the mouse position. But both use different origin points so its gonna be tough

[rough venture]

Yup! That fixed it That sucks, honestly. I would expect better of a 3k laptop. Well, well, well

[teal viper]

laptops always have to make compromises due to size

[languid spire]

should not be a problem using ScreenToWorldPoint for the mousePosition

[wary gale]

Okay thanks for the help ill check it out

[queen adder]

have someone made a nice way to call static methods in unityevents before?

[rare basin]

if I have a static class, and a static int variable inside that class, and If i modify that variable during runtime, would the value be changed back to default when I run the game or it will automatically save? do i need to handle the saving myself?

public static class SaveSlotStaticManager
{
    public static int currentSaveSlotId = 1;
}

[teal viper]

It would reset

[rare basin]

alright, thanks

[queen adder]

easysave saved me all the troubles about any persistent data, I had a working save system before that I wrote for a week and easysave is a ton better than mine

[shell sorrel]

would reset, you would need to save it into persistient data or to playerprefs manually

[slender bloom]

following a yt tutorial to make flappy bird, and the text is the same as the video except im not getting the dropdown for variables, his code also looks more colourful than mine

any ideas whats wrong?

most likely a hardware limitation of your keyboard

[golden ermine]

Why it doesnt recognize Im clicking E and nothing happens idk why it should open up menu, this is code its small so I screenshoted

[rich adder]

how did you verify that OnTriggerStay actually runs

also the second one should be inside an If else statement no If, because just incase the second one could run

[golden ermine]

because my interactInfo appears

[slender bloom]

Not sure why its not recognizing vector3 in transform

[golden ermine]

here but this doesnt fix it

[rich adder]

well did you check the first thing I said , the log

[rich adder]

what is vector3

[cosmic dagger]

check the Unity docs for vector3 . . .

smth looks fishy about it . . .

[golden ermine]

@rich adder i did here

[slender bloom]

Should be the X axis here,,,

[cosmic dagger]

did you go to the Unity docs page for vector3?

[scenic knoll]

Hello guys, i dont know if this is a good channel to ask this i just legit joined but i am looking for some guidance in terms of creating a simple "turned based game". I am wondering if i could dm someone with a prototype of the game that i have done like years ago (its the interface and concept art of it in photoshop) in order to know if what i done there can be done in Unity and if its worth to do it in Unity or if i should maybe do it in any other language or engine.
Thank you.

[wintry quarry]

Unity can make any kind of game you can imagine.

[slender bloom]

ive configured it, and am using vector2 the same way in another script for the level

[wintry quarry]

according to that latest screenshot, you certainly have not

[rich adder]

no way you are

[wintry quarry]

It would not say this if it was configured

[terse moat]

Its not vector3 its Vector3?

[shell sorrel]

we all know that but we wanted them to find out why and configure the tools so it tells them

[slender bloom]

im a idiot

[terse moat]

oh mb.

[golden ermine]

it works but only if Im moving inside of trigger and I cannot exit it, its weird and buggy but it shouldnt be

[cosmic dagger]

NOOOOO! 😱

[slender bloom]

unless it reverted back i configured it

[rich adder]

btw it would've been obvious what you needed, had you looked up the Vector3 documentation like RandomUnityInvader said
https://docs.unity3d.com/ScriptReference/Vector3.html

[wintry quarry]

you have only done one step

there are many steps

follow them all

[cosmic dagger]

that's only part of it. did you finish the rest of the setup?

[scenic knoll]

I worked one few projects which was the same game i wanna work in, but the game was extremely old and had an old interface, i had the job to upgrade the old interface and add a modern element to it so i just had done the concept art of it in Photoshop, but i guess the programmers were too lazy to do it or couldn't, so they ditched it. Then i also had another project with another name where the leader used Unity, but he still used the old interface and stuff.

Basically my dream concept art for the game was not done and i decided to try to make it into reality, wondering if i could do it using Unity and if its worth it. I don't expect to make this game playable but mostly to just learn programming/coding, and since the only way i think i will have fun learning is to create a game and maybe a project i always wanted to do. What would be your advice if possible?

[slender bloom]

was looking at this page having a brain fart moment

[rich adder]

put keyInput inside triggers is never a good idea although onTriggerStay should be ok but maybe KeyDown not GetKey (somewhat)

[wintry quarry]

wondering if i could do it using Unity and if its worth it

Yes as I mentioned, you can make any game you want in Unity. As with any game engine you will have to learn it first. Unity is one of the easiest game engines to learn while also being one of the most powerful and flexible.

[golden ermine]

then how should I handle it

[rich adder]

always search the "Scripting API" for code related stuff

[cosmic dagger]

click on Scripting API to the left of the search bar (where you typed "vector3") . . .

[rich adder]

you typically make a bool for them inside Update you capture them then use it inside OnTriggerStay as you need

   bool useKeyHeld;
   private void Update()
   {
       useKeyHeld = Input.GetKey(KeyCode.E);
   }
   void ontriggerstay()
   {
       if (useKeyHeld)
       {
           //watever
       }
   }```

[slender bloom]

ahh thanks

[scenic knoll]

I see, would it be possible with your permission to send the print screen to your dms of what i wanna do and maybe if possible you could just tell me what i should search for on youtube or something like that to get started? Like i said, this is not a 3D game or an actual card game, its mostly just images from an Anime and then the interface and the functionality of it behind it. I was trying to learn programming tru cs50 course by harvard and then odin project but i got stuck making a mugen game in scratch, decided to ditch it and try to make my dream project from years ago while actually learning how to code, but unsure what language would be the best language since i also dont know if i wanna be a game developer or anything else, so mostly unsure about the programming language i should choose.

[rich adder]

btw you can also do something like this

    bool isInsideKitchenArea;
    private void Update()
    {
        useKeyHeld = Input.GetKey(KeyCode.E);
        if(useKeyheld && isInsideKitchenArea)
        {
            //do whatever
        }
    }
    void OnTriggerEnter()
    {
        if (tagCheckForKicthen)
        {
            isInsideKitchenArea = true;
        }
    }
    void OnTriggerExit()
    {
        if (tagCheckForKicthen)
        {
            isInsideKitchenArea = false;
        }
    }```

[wintry quarry]

You would be better off starting with learning the basics of the engine

before jumping straight into making your specific game

this is true for any engine

For Unity I recommend !learn

[eternal falcon]

:teacher: Unity Learn ↗

[wintry quarry]

However, in general for a turn-based game you'll want to learn about state machines.

[scenic knoll]

since unity's language is c#, is it not worth to learn programming by creating a game in Unity in case i don't actually wanna be a game developer later on, but for example become a software enginner or a web developer? Afraid of choosing a language right now that i might not stick with. I don't have much time

Damn my brain got confused by my own question

[polar acorn]

Switching programming languages is honestly pretty trivial

Once you learn a language, it won't be more than a day or two to get up to speed

[scenic knoll]

Yeah i get that, but where else do people use the c# language? Other than game development

Just to know my options in case

[verbal dome]

C# is used for web+software dev too

[polar acorn]

It's a fully formed, turing-complete programming language. You can use it basically anywhere for anything, like most other programming languages

In the business world, a programming language is basically "Whatever the first guy likes" and there's very little consideration put into any specific reasons

[timber tide]

more like "whatever the first guy used 20 years ago"

c# does seem more common than java for the past few years though

[shell sorrel]

yeah C# is pretty decent for almost every purpose but like really high performance stuff and embedded

also the hard part is learning to program, once you do learning new languages is not a big deal

[rich adder]

I'm using to make a real life HUD onto hardware from a unity game, and ofc I'm using C# to communictae that data with my C++ controller that controls a screen

[mint remnant]

didn't microsoft adopt is mostly to overthrow Java's dominance at the time?

[shell sorrel]

There are jokes it's MS Java

So yes

[polar acorn]

It's not jokes it literally used to be named "Microsoft Java"

[wintry quarry]

Almost everywhere. It's one of the most popular programming languages.

But as others said - once you know one programming language, it becomes very easy to learn a second, and a third, and so on...

[scenic saffron]

How do i add/subtract the Input of an Input field to an Integer or float?

[polar acorn]

If you just need to check equality, the easiest way would be to call ToString on the number and check if the strings are equal

if you need to do math like a less than operation, you'll need to do int.Parse to turn the string into an int. Note that this will throw an error if the string isn't formatted properly, you might want to use TryParse instead and handle the case where the string is malformed (such as when it's empty)

https://learn.microsoft.com/en-us/dotnet/api/system.int32.parse?view=net-8.0
https://learn.microsoft.com/en-us/dotnet/api/system.int32.tryparse?view=net-8.0

[scenic saffron]

ok thx

how do I prevent negative numbers from being input in my input field

[languid spire]

https://docs.unity3d.com/2018.1/Documentation/ScriptReference/UI.InputField.ContentType.html

[scenic saffron]

all of them allow negative numbers or allow other characters

[tender stratus]

WHy?

[eternal needle]

It tells you why, it's a method. You dont assign to it, you call the method with the parameters

[languid spire]

dont use a = sign with a method

[tender stratus]

Yep silly me

didnt even notice the =

Thanks i went on autopilot there

[scenic saffron]

how do i set up a input field so it only positive integers?

using this

[slate nexus]

Recently i decided to start making games in unity. I started by watching a tutorial and made a simple flappy bird game. But everytime I try to send my game to a friend of mine it always has lag spikes for him, i tried running it on my pc and it works just fine, i also tried zipping and unzipping to see if it was something with that but no. Note my friends pc is better than mine so theoretically it should be better.

[teal viper]

There's not much you can do aside from profiling the game on their PC. Or asking them to profile and send you the profiling data.

[slate nexus]

ok ty for your response

[shell sorrel]

you might be able to profile a build on yours and look for spikes as well, just might be more extream in their case

does your game happen to be instantiating and destroying lots of objects?

[warm summit]

hey, i followed the Instruction for custom controller but in my case the only thing that doesnt work with my custom FPS Controller is that the Input goes to the player while using the GUI.

Does anyone a fix for that?
I tried some ways, but it wont work.

i would appreciate it. 🙏🏼

[slate nexus]

I profiled it on my pc only spikes where when i paused or alt tabbed but not enough to lag a lot

[slate nexus]

yeah it does

[shell sorrel]

good chance the spikes are caused by garbage collection, if its constantly the same objects being created and destroyed

look into object pooling

[slate nexus]

ill see what i can do

[shell sorrel]

there is a big overhead to destroying objects so the idea is instead of destroying it, you just disable it and restore it to its starting settings

[teal viper]

Can you share a screenshot of the profiler graph from around the same point in game where it lags for your friend?

[shell sorrel]

then when needed next grab one from teh pool

https://docs.unity3d.com/ScriptReference/Pool.ObjectPool_1.html

[slate nexus]

i think its constant lag spikes

[teal viper]

if(!uiOpen)
    //Process input

[slate nexus]

i still dont understand why on my pc it works just fine?

[teal viper]

There could be a million of reasons.

[shell sorrel]

it could be many things

do you happen to have more ram?

[slate nexus]

nope

his pc is better

[teal viper]

Do they use a laptop? Maybe they have it use the integrated GPU?

[slate nexus]

no

[teal viper]

Well, then you'll have to profile it on their machine to figure it out.

[slate nexus]

ok ill try sometime when i can

[shell sorrel]

it is possible to profile across a local network btw, so you do not need to have unity on their machine to do so

[teal viper]

But might need to use a VPN.

[shell sorrel]

just the game, and your dev machine on the same lan

yeah i was assuming in person

[slate nexus]

ill try to export it to him

[steep rose]

since those websites do the exact same thing as these

[strong wren]

oh sorry i just find these alot easier

ye but it says to make an account and stuff, i dont rlly liek doing that

[dark laurel]

they all do the same thing more or less

then use pastebin, free, no account needed

[steep rose]

you dont have to, i dont think

oh, sorry im just to slow if its not like 3 buttons to click then it just gets to hard

hastebin for example is just copy paste click copy button boom

programming may not be for you

pastebin = hastebin

[strong wren]

ok

[steep rose]

pastebin is hastebin but via larger corporation

[slate nexus]

its not constant tho

when he alt tabbed back it was smooth

[steep rose]

do you have anything in your game like loading, scene loading, etc?

and stutters usually happen when something graphically demanding is happening on screen and its creating a bottleneck with you CPU/GPU

[slate nexus]

no its an extremely simple game

[steep rose]

explain "extremely simple"

[zinc seal]

Hey, i'm following danis old movement guide and whenever I move my camera up and down my player moves up and down with it? It is hard for me to tell whats going on.

[wintry quarry]

you likely did something wrong when you set up the hierarchy and/or assign object references on your scripts. Or you copied some code incorrectly. Hard to say really.

[steep rose]

you seem to be rotating the player

[shell sorrel]

you can place the cursor at the spikes and get more detail about exactly what is taking the time

[slate nexus]

isnt it the vsync?

its the same color

[shell sorrel]

yeah still a good idea to look at the detail, also vsync can be a bit of a red hering

[slate nexus]

ok ill see

[shell sorrel]

more or less if things are v synced at say 60hz, and soemthing eats a bunch of time, and causes it to not be able to keep up and say you can only render 58 frames a second

well the vsync will sync to 30hz causing a large spike in its time when its just in response to something else

[slate nexus]

wouldnt just disabling the vsync solve my problem?

[shell sorrel]

would reduce the scale of the spikes, and make it easier to see the true cause sure

but having no vsync can cause issues as well, like screen tearing as the frame rate exceeds the displays refresh rate which is the problem vsync is designed to solve

[slate nexus]

mhm ok ill see how it works without

[shell sorrel]

but yeah if you look at the spike the profiler can show the whole break down of where all the CPU time is being used for that frame

[slate nexus]

one sec my friend is opening it rn

ill share screenshots of it

this is with the vsync graph disabled

[tender stag]

@rocky canyon
https://youtu.be/QznVNFlz_jg

somehow this limits the velocity at which the player can move

and it also allows him to go beoyond the max speed

how do they do it

[umbral rock]

hey there! i'v installed visual studio code and i am following c# courses but i need a workload called Universal Windows Platform Development, anyone knows how to install this when i'v already installed vscode?

[steep rose]

i actually made my own quake/halifelife movement system and its almost a 1.1 replica but what i did is apply a force in the opposite direction of movement so if you strafe you could easily go past it, of course you need a max speed for strafing but its the same thing with some multipliers to slow the player down effectively

he probably is doing something similar

since this is what halflife/halflife 2 does

[tender stag]

my question is like how do i limit the force from player input without limiting speed

im not really making a strafing/surfing game

[steep rose]

cancel/ignore the inputs if thats what you are talking about

[tender stag]

isnt that a bad way

as in like when im turning lets say

it wont always turn

[steep rose]

no

it will just stop you from turning more

[wintry quarry]

Make sure you're not confusing Visual Studio and Visual Studio Code

[lofty sequoia]

Is there a way to rename a variable but preserve the inspector reference?

like you said to cancel out the inputs

thats what i did

and it doesnt work

[steep rose]

well i cannot see X or Y or see how fast your RB is actually going so i cannot really tell you why its not working.

i should ask How is it not working?

[tender stag]

its not limiting the speed

[steep rose]

on the ground or in the air?

the speed limiting will only work on the ground since you are using dani's code

thats just how it works

[tender stag]

both

https://hastebin.skyra.pw/gejehunuza.pgsql

this is the whole code

[eternal needle]

I dont see anything there that actually limits the velocity

[steep rose]

well the first thing i see is a ton of nesting

[eternal needle]

That's definitely some code. That ternary

[tender stag]

wdym

[tender stag]

because there isnt

[eternal needle]

If you want direct control of what the velocity should be, then just assign the velocity to what you want. addForce doesnt apply right away, it happens during the physics step

[eternal needle]

Then how is this an issue if you know your code doesnt limit it

[tender stag]

i cant set or change the velocity

i cant touch that

i want external forces working on the player

as well as limiting the movement speed

[steep rose]

also dani's code relies on its own friction so thats also a reason its not working

[eternal needle]

And what's stopping you from doing this? You dont have to hardcode what the velocity is. You just add or subtract to it and suddenly that works

[steep rose]

what are you trying to do exactly

[eternal needle]

But still, if you're not limiting the velocity I dont see why your problem is the velocity isnt being limited

[tender stag]

i explained it 20 times

[steep rose]

we joined this conversation late so you have to fill us in so thats why i asked

[eternal needle]

Simply put, you cant. The rigidbody doesnt store what an "external force" is. You store this yourself if you want to or dont want to limit that

[tender stag]

other games seem to do it

minecraft for example

[steep rose]

you have to make those forces yourself to act against the RB

it wont just happen

like you think it will

[eternal needle]

Did you read the last sentence I wrote? Because it really feels like this is going nowhere. I said you cant, meaning only using the velocity from the rb. You have to store it yourself

[eternal needle]

In which case, you do exactly what I already suggested.

[pastel wedge]

How do i fix this

[deft grail]

Download it?

[pastel wedge]

i did

just was failing to set the path

[deft grail]

Did you restart vs code?

[pastel wedge]

yea

[obsidian granite]

Use an IDE that will blow up your computer (vs)

[rich adder]

did you restart the PC

the pc needs restart for PATH to update properly

[pastel wedge]

yeah i did restart, ima retry tmr was prolly due to my ide being on a different drive to vs code?

[rich adder]

ide being on different drive to vscode ?

vscode is ide

[pastel wedge]

yeah im p sure i extracted net sdk in downloads folder which is on a diff drive to my main so that could be it

[pastel wedge]

ment net sdk

[rich adder]

just to be clear you should Install dotnet **SDK ** version on C: drive. Shouldn't matter where VSCode is as long as you can get dotnet command running in command line in main OS path

sum like this

[late burrow]

will this thing even fit into float

[wintry quarry]

paste it as text

[short hazel]

Easy check, immediately log the value. Convert it to a string first because Debug.Log rounds it for visual purposes

spoiler: it doesn't store this exact value

[wintry quarry]

Paste it in here https://www.h-schmidt.net/FloatConverter/IEEE754.html

(in "decimal representation")

nope, not exactly

[late burrow]

i know theres doubles and such

what if i go out of these bounds as well/

[wintry quarry]

then... you do

[late burrow]

it was for math

[wintry quarry]

the consequences of that really depend on what you're doing

everything is for math in the land of computing

If you really need absolute precision - there's things like https://github.com/AdamWhiteHat/BigDecimal

[short hazel]

Absolute precision can be achieved with the decimal type, at the expense of range, values cannot get too high or too low

[wintry quarry]

decimal has limited precision as well

just 4 times as many bits to work with

[short hazel]

Enough for their number

[late burrow]

yeah i wondered if i can extend limit of bytes for variable

to use as many as i want

[wintry quarry]

Through software, like my link above, yes.

Your computer's hardware is limited to numbers represented with a certain number of bits - usually 64

And possibly up to 128 with some special instructions (which I think is how decimal works?)

[short hazel]

decimal takes up 128 bits but only 102 are really used. The mantissa is bigger than other floating point types (96 bits) so you have an accuracy of around 26 decimal digits

[queen adder]

    void VelocityControl()
    {
        Vector3 currentVelocity = new Vector3(rb.velocity.x, 0, rb.velocity.z);

        if (currentVelocity.magnitude > current_state.speed) 
        {
            Vector3 fixedVelocity = currentVelocity.normalized * current_state.speed; 
            rb.velocity = new Vector3(fixedVelocity.x, rb.velocity.y, fixedVelocity.z); 
        }
    } 
    void SurfaceCheck()
    {
        onSurface = Physics.CheckSphere(surfaceCheckPosition.position, sphereRadius, surfaceLayers);
        if (onSurface)
        {
            rb.drag = surfaceDrag;
        }
        else
        {
            rb.drag = airDrag;
        }
    } 

Your player also needs to have a 0 friction physics material, and some sort of Ground and Air drag like here

        if (onSurface)
        {
            moveDirection = orientation.forward * verInput + orientation.right * hozInput;
            rb.AddForce(moveDirection.normalized * current_state.speed * 10f * rb.mass, ForceMode.Force);
        }
        else
        {
            moveDirection = orientation.forward * verInput + orientation.right * hozInput;
            rb.AddForce(moveDirection.normalized * current_state.speed * 10f * rb.mass * airMultiplier, ForceMode.Force); //Times "Air multiplier"
        }

And some sort of air multiplier

This is my controller

[tender stag]

does it allow external forces?

as in if i add a suffen explosion force to the player

[queen adder]

Yes, its AddForce based and not Direct velocity manipulation

[tender stag]

alright thanks so much man

i’ll try it in the morning because im going to bed now

i’ll let you know if it works

[queen adder]

Yes please, I would like to help you implementing it when youre ready

[brave compass]

Also importantly, decimal stores numbers in decimal format instead of binary like double and float. So fractions like 0.1 will be represented exactly, instead of an approximation like in binary.

[tender stag]

one more question though

your setting the velocity once hes above the speed limit

so your directly changing the velocity

[queen adder]

Thats true, but Ive used this system for a very long time, including in explosions, and it doesnt seem to cause any issues

You can also put that into a bool, so when the bomb explodes you can turn off that speed control if it does cause issues

[tender stag]

i mean true

i mean if i dont figure it out tommorow then im probably going to stick with that

[queen adder]

Yeah, Rigidbody controllers are a massive pain

[eternal needle]

Just saying, that code above doesnt account for what you were describing some time ago. As I said before, there is no "external forces" stored on a rigidbody. everything is an external force. The rb just stores the current velocity, which may have been a combination of a bunch of forces applied

[tender stag]

i know

but theres no other way to describe it

[wintry quarry]

There's actually a huge caveat to this - and kind of "best kept secret" about Rigidbody...

Rigidbody has this: https://docs.unity3d.com/ScriptReference/Rigidbody.GetAccumulatedForce.html

Which tells you the sum of all the AddForce calls up to this point which haven't been applied in the Physics Simulation yet.

You can calculate what the new velocity will be with this

[eternal needle]

I'm not sure that applies to their problem. What I understood was they wanted to limit the speed from a players input but not like explosions

[wintry quarry]

Well it can help with tracking such forces

[teal viper]

In case you didn't get an answer, it is vsync and it acts very abnormally. To be honest the whole capture looks very abnormal. The game execution itself barely takes any time.

[eternal needle]

Even that method just returns a single vector3 of the force. Theres no difference if it came from 1 script used for movement or another knockback script. Im not entirely sure if I understood their problem but I dont think itd work because theres no information about where forces came from. I do think it's just solvable by keeping track of the external stuff themselves instead of having other scripts addForce directly to the rigidbody.

And then another thing to consider would be how long to apply those forces for

[wintry quarry]

Well usually I think of "external forces" as "things bumping into the object" which is different from forces caused by AddForce, and don't show up in that method. It's true if you have two categories of forces added with AddForce and you want to isolate one or the other, you'll need to track them yourself.

As for "how long" - it doesn't matter too much, you would just do the tracking and compensation each physics frame.

[eternal needle]

Ah I didnt consider the actual collisions

[rocky canyon]

i was explaining to him earlier that I would project the would-be velocity of my movement before adding the rest of the forces.. then he could just limit his movement forces.. i wasn't even aware that rigidbody even had this 👍

[tender stag]

im talking like adding sudden force to the player

to launch him to the side

[wintry quarry]

Letting the cat out of the bag - I use this extensively for the speed limits feature of my asset https://www.youtube.com/watch?v=dRtHHhhKUn4

[rocky canyon]

ohhhh... thats YOURs

[wintry quarry]

yep!

[rocky canyon]

well i'll be

i think everyone in this server now knows what he's trying to do

[tender stag]

lmao

[rocky canyon]

i tested my implementation earlier.. and it works.. just projecting the would-be velocity of the player movement.. and then adding any other movement later in the loop.. (i added a THRUST FORWARD) mechanic

works great

can only move 10 units/sec with WASD but can boost up to 30 or 40 if u hit the boost button enough lol (while having the movment only contribute 10)

[tender stag]

thats exactly what i need

what do you mean by projecting the would be velocity

[rocky canyon]

ya, ive told u how to do it before.. but not 1:1 ofc cuz i dont know ur mechanics

[wintry quarry]

vector projection. Vector3.ProjectOnPlane(...)

[rocky canyon]

well thats one way cs void ApplyMovement(Vector2 input) { // redacted til bug sorted } i did this route

may not work in all use-cases tho.. ive only tested it in a straight line lol

[rocky canyon]

ohh yea this is probably better.. b/c just noticed my gravity does affect it

[tender stag]

might not work well while turning

im not sure tho

i’ll check

[rocky canyon]

could also be true.. hold im testing the projection onto the plane (before my limiter)

that may be still fine

nope, theres a bug in mine somewhere

lol

[radiant meteor]

how do i get an array/list of every Game Object with a certain component in a scene?

[tawdry trench]

does anyone know why this comes up as a list instead of an empty array?

[deft grail]

thats not coming up as a list

[teal viper]

You can use findobjectsoftype. Though it's a pretty heavy thing, so might want to reconsider.

[tawdry trench]

but when i made na empty array before it would have the black spaces open like this

[rich adder]

thats an array, also you do not see 6 because you serialized it when it was 0, now you put 6 in the script. The original serialized value of 0 is there, you can right click script also and do reset .

[deft grail]

thats becasue you assigned 6 slots to it

[tawdry trench]

i c

[rocky canyon]

press the + sign 6 times

then it'll look familiar for ya

[deft grail]

or just type the number 6

[rocky canyon]

lol.. rekt

[rich adder]

or just reset the script lol

[tawdry trench]

i see so the 6 i wrote in the code just doesn't do anything?

[deft grail]

yes and no

[rich adder]

not if the value serialized was originally 0

[deft grail]

if you do that before adding the script to your gameobject, then it does something

[rocky canyon]

.. unity quirks

[rich adder]

if you right click it and hit reset then initilizer values will refresh

[rocky canyon]

pro-move ^.. until its a pro-disaster lol

[rich adder]

but this will reset everything else so use caution

[steep rose]

but in short yes, please ask

[spark stratus]

Lol man completely missed that .

So short version, I'm trying to make a top down, 3d game that uses mouse input to control the direction the player faces, but the wasd keys to control the movement(Where W would move the player in the direction of the mouse). So far(With some tutorial code) I've been able to get the movement to work the way I want, and the player to rotate direction with the mouse, but the camera(Despite being a child of my players GameObject) won't follow the player when i have the code that moves the player forward.

https://pastebin.com/mxUE4fL0

Hierarchy of the player object is as follows
GameObject with various scripts
-Mesh, animations etc from blender
-Camera

Oh and I forgot to mention, the only way I could get the player to move forwards correctly was to include the line

        if (Input.GetKey("w"))
        {   
            transform.position += transform.forward * 5 * Time.deltaTime;
        }

in the camera script

which seems janky as fuck

[steep rose]

i would move the camera independantly with the player like
camera.position = Player.position + vector3(0 , 0 , 0)//some offset if needed;

and keep in mind moving the transform of the player will ignore collisions

[spark stratus]

hmmmm I defintely don't want to lose collisions. Is there a better way to get the character to move(Specifically in the direction it's facing)?

I went with transform.position cuz it was the only thing I could hack together that worked lol

[steep rose]

well what i do is have an "orientation" object on my PlayerOBJ which rotates and use that transform to either apply a force if using RB or use Move() if you are using a character controller

both respect collisions

you can also directly set velocity or a RB as well which also respects collisions

[spark stratus]

Will do some digging to decide the best way to move forward, appreciate the help!

[queen adder]

{
Debug.Log("Test");
    if (collision.CompareTag("Bullet"))
    {
        Destroy(this.gameObject);
    }
}```


Very confused why this isnt working when the object tagged Bullet enters nothing happens but the Debug

[deft grail]

then it doesnt have the Bullet tag

did you make sure the thing your colliding with actually has that?

[queen adder]

Yes the bullet object has the tag

[deft grail]

can you show that?

[frosty hound]

The debug is outside the compare tag check, it's not detecting any triggers.

Presumably, you're missing something such as a rigibody2D, or setting the collider to be a trigger, etc.

[queen adder]

The debug works but the if statement isnt the bullet is tagged with Bullet which is shown in the screenshot bullet has a box collider and is a trigger and the enemy has a box collider and a rigidbody

[deft grail]

wait is this script on the bullet?

[queen adder]

no it is on the enemy the bullet only has a moveforward script

[slender nymph]

have you considered printing what was hit as well as its tag instead of just "Test"?

[vocal wharf]

Hi! I am making a very basic open world 3d car game and right now I am working on a speedometer. I have a TMPro text on th canvas and I made up my own code to get it to constantly display my rb.velocity but my problem is that it has a lot of decimal places and I will like to round it to the nearest integer. I found out about Mathf.Round and looked up the doc for it and tried to implement it but it makes no change to my speedometer readings. Can someone help me please?
I have the rigidbody movement code in Fixed update (I left that part out because it is unrelated and not connected to this code at all) and part of the speedometer code in regular update. Is this correct?

void FixedUpdate()
    {
        currentSpeed = rb.velocity.magnitude;
    }
    void Update()
    {
        Mathf.Round(currentSpeed);
        speedometer.text = (currentSpeed + " mph");
    }

[queen adder]

I have the debug there to make sure its actually detecting the trigger and it is

[slender nymph]

right but that doesn't actually provide useful info. but you can print that useful info instead

[deft grail]

you can get rid of the decimals by using .ToString

[vocal wharf]

Where do I put the .ToString?

[queen adder]

The info is useful its telling me that the trigger is working which is all I need it for

[deft grail]

where you set the text

[solemn summit]

currentSpeed.ToString() + " mph"

[frosty hound]

Spend less time resisting help and just do the thing that will help people help you.

Knowing what you're hitting is exactly how you debug your issue.

[slender nymph]

but it isn't useful because you don't know why the comparetag isn't working but printing that information will make it obvious why it isn't working

[deft grail]

doesnt really tell you its working, since it works with some random object instead of your Bullet

[fierce shuttle]

Dont you have to specify the format in ToString as well?

[deft grail]

yeah

well you dont "have" to

but for this case you should

[vocal wharf]

Thank you 👍

[queen adder]

That isnt my issue im failing to understand why it would help the bullet is the only trigger in the scene so it cant be a random object and the trigger of the bullet is running the Debug but it isnt running the if statement that means something is wrong with the compare tag which I dont know what is wrong with it

[frosty hound]

Okay, good luck then.

[vocal wharf]

@deft grail @solemn summit hmm it still displays many decimals

[queen adder]

Am I on my own for this one lol

[deft grail]

add a "F0" i think inside the ()

[frosty hound]

Certaintly not getting help from me, I don't waste time with people who are resistent to help. Hopefully someone else here is willing to suffer through it.

[queen adder]

Im sorry how am I resisting help?

[frosty hound]

Again, not wasting time. No need to respond/ping me further, thanks.

[deft grail]

send a screenshot of the Debug.Log stating the object you hit

[vocal wharf]

Now unity gives this error even though MS visual studios shows no syntax errors

[queen adder]

[deft grail]

uhh show how you did it?

Did you put it in quotes? "F0"

[vocal wharf]

void Update()
    {
        speedometer.text = (currentSpeed.ToString(F0) + " mph");
    }

[deft grail]

whats confusing? change your debug.log to output the thing you collided with and screenshot it

[deft grail]

oh nvm I lied visual studio shows a syntax error too 😂 my bad

[slender nymph]

you insisted on not printing out useful information which is literally how you debug this issue. so you were literally resisting the help being offered by not doing the one thing you need to do to figure out why this is not working the way you expect it to

[vocal wharf]

I closed visual studio before it had time to display the error 😂 too impatient I guess

@deft grail yes it works now, only shows integers. Thank you very much

[queen adder]

I apologize im confused what is the info gonna tell me I dont understand.

[deft grail]

just do it...

[solemn summit]

My guy. Please, I am on my knees, pleading, begging. Do what they're asking of you. This is an important lesson in debugging.

[slender nymph]

if you print what was hit and the tag of the object that was hit, then you'll see exactly why the compare tag call isn't working because you will see what was hit and its tag instead of making assumptions about what was hit because of how you think things are set up

[queen adder]

How would I log that?

[queen adder]

Im really not trying to be difficult or anything like that I genuinly dont understand

[slender nymph]

with Debug.Log and using the Collider2D provided as a parameter for the method you will be calling that inside of

[solemn summit]

Debug.Log(collision.gameObject + ": " + collision.gameObject.tag);

Insert 'firmly grasp it' gif

[slender nymph]

or even better: Debug.Log($"{name} overlapped {collision.name} with tag '{collision.tag}'");

[queen adder]

 {
     Debug.Log("Test");

     if (collision.CompareTag("Bullet"))

     {
       
         Destroy(this.gameObject);
     }
     Debug.Log(collision.gameObject + ": " + collision.gameObject.tag);
 }
 }```

Alright did that this is what it gives me

[slender nymph]

copy my log and use that

[deft grail]

can you screenshot this code in your IDE as well

[slender nymph]

i'm betting there's whitespace in it

[slender nymph]

have you confirmed whether OnTriggerEnter is being called or not?

i'm going to go ahead and guess right now that it isn't considering you're moving this object via its transform rather than with something that would ensure that would be called like a Rigidbody or CharacterController

[supple wasp]

is that all that is in setbool all the parameters have the setbool

[slender nymph]

huh?

you don't need to be in debug mode

[slender nymph]

if it has a rigidbody on it, then why are you moving it via the transform?

even still though, have you bothered making sure that OnTriggerEnter is actually being called?

That's to put it right because it's not going in the direction from where it is.

...?

[slender nymph]

whatever that message was supposed to mean though, it still does not answer the question i asked. i did not ask about its tag, i asked if you have confirmed whether the OnTriggerEnter method is actually being called

[remote lynx]

help please

[slender nymph]

do you ever plan on actually providing a description of what you think isn't working? those of us who have not been working on your project directly do not have the context needed to know just from your video (half of which was spent just waiting)

[remote lynx]

when there is only 2 answers to the questions i set the anchorMax of the 0th and the 2nd answer to the 1st and the 3rd answers anchorMax and then when there are 4 questions it should go back to default but it doesnt

[silk night]

Instead of changing it via Code, I suggest you take a look at horizontal Layout, vertical Layout and grid components

[remote lynx]

I dont actually have time to code it from scratch

[silk night]

Thats the neat part

No coding needed, they just align the items for you

[slender nymph]

yeah layout groups are going to require much less code

[remote lynx]

Docs?

[slender nymph]

but i would also like to point out that you are not resetting the anchors on those objects, you are resetting their offsetMin and offsetMax

although rereading the information that may not be the issue so you can probably ignore that

[remote lynx]

Why does it work in editor but not in the player though?

please do not post random files here

[grim shuttle]

this is a file for beginner code - guess its wrong place to post then?

It is only for Unity development of games

[languid spire]

you posted a file with no explanation of what or why, so yes this is the wrong place. #1180170818983051344 would be more suitable

[grim shuttle]

nice thanks

I thought the file name was explanation enough opps

you dont think I could post a virus with the same name?

[calm badge]

Hi, does anyone have an idea/experience for integrating a 3D avatar into a mobile app?

[ivory bobcat]

This is the beginner coding channel, you should perhaps ask in a more appropriate channel. Like #💻┃unity-talk #📱┃mobile or whatever would fit the criteria.

[calm badge]

Alright thanks

[paper sable]

hey, i was thinking that i could save some resources by only rendering the objects that are in the player's camera view so i did that and it works pretty well, but if i get too close to an object, it also disables its renderer, does anyone know if i did something wrong in my code?
this is the script that i apply to all the objects in my scene

void Start()
    {
        camera = Camera.main;
        renderer = GetComponent<MeshRenderer>();
        bounds = GetComponent<Collider>().bounds;
    }


    void Update()
    {
       if (!renderer) return;

       cameraFrustum =  GeometryUtility.CalculateFrustumPlanes(camera);
       
       if (GeometryUtility.TestPlanesAABB(cameraFrustum, bounds))
       {
        renderer.enabled = true;
       } else {
        renderer.enabled = false;
       }
    }

[slender nymph]

what you've described is called frustum culling. and unity already includes it

[paper sable]

so the thing im trying to do is useless?

[slender nymph]

yes because unity already does it for you

[keen dew]

All that does is add extra overhead and a source of potential bugs

[paper sable]

alright, im not going to use the code anymore. thanks for telling me guys

[formal hill]

I can't seem to figure out why my enemies are invisible. Can someone help me out? (They were visible before I made the enemy spawner)

[keen dew]

Check that they don't spawn behind the camera

[formal hill]

What do you mean behind the camera?

[keen dew]

I mean that if they're behind the camera then the camera won't see them and they won't be rendered

[formal hill]

How do I check if they are behind the camera?

[keen dew]

What's the Y position of the enemies when they spawn, and what's the Y position of the camera and an object that is visible?

Or pause the game, go to scene view, turn on 3d mode and see where they are

[formal hill]

Is it because the enemy spawners y position is minus?

[keen dew]

What's the Y position of the camera? ¯_(ツ)_/¯

[formal hill]

It was 1! Thanks

I didn't know I could go to 3d mode in 2d

😅

[vague oyster]

help please

[languid spire]

you might like to post a translation of the error messahe, not everyone can read Russian

[vague oyster]

it says that animator does not contain such a definition

[languid spire]

like this

[vague oyster]

this is strange because I don't have a class called animator

[wet raptor]

I am trying to make some colliders on an isometric grid. The colliders seem messed up and curved, not like a grid at all.

[languid spire]

show the screenshot

[vague oyster]

I think I understand

[wet raptor]

Sorry if I should be adding more detail to my first message, I haven't really posted here before.

[vague oyster]

I clicked on this class in the ad and this opened up for me

[languid spire]

So you DO have a class called Animator

[vague oyster]

there is no script in the files with the name animator, but for some reason the file name is glow animator, while in the script it is simply called animator

[languid spire]

I did not ask you if there was a file called Animator, I asked about a class. That restriction has been lifted in latest versions of Unity

[vague oyster]

as it turned out, there really is a class. In any case, thanks for the help, I think I understand what to do next

[ripe vigil]

anyone know what to do im following tutorial and they dont got this

[teal viper]

These samples probably require you to install some packages or enable certain settings. Did you go over the installation instructions?

[ripe vigil]

idk whats going on

can u vc?

[teal viper]

No.

[teal viper]

Where did you get these samples?

[ripe vigil]

can we vc u mute so i can screen share

[teal viper]

There should be a readme or some info at least.

[teal viper]

No.

[ripe vigil]

i got them in

[teal viper]

You can share a screenshot

[ripe vigil]

ok well

[teal viper]

Or record and share a video here.

[ripe vigil]

the samples are

idk where but

its in projec setings

[ripe vigil]

how do i see my samples?

com.unity.xr.interaction.toolkit thats something i put in in the plug in things

[teal viper]

You have samples folder in the assets. They're not something included in unity by default.

[ripe vigil]

how do i see them then

[teal viper]

You can see them in your assets folder. I'm asking where is that samples folder from?

[ripe vigil]

im starting a new thing so i can restart without the errors

[neon ivy]

about to make a ground check (3d not 2d if that matters) with the tried and true "just a raycast down", was wondering if anyone had any ideas for something more or is this truly is the end all be all?

[cosmic dagger]

either that or a SphereCast/OverlapSphere . . .

[wintry quarry]

Depends on your requirements

It's a pretty good way..what prompted the question, is it not meeting your needs?

[neon ivy]

I mean I can assume it's the best way for me to do it or I can ask more knowledgeable people if my assumption is wrong

call it curiosity or just learning

[wintry quarry]

"the best way to do" something always depends on the something you're trying to do. Every game has different needs

The shape and movement style of your character is a huge factor

A simple Raycast down wouldn't cut it for a complicated worm shaped character for example.

[neon ivy]

that does make sense, I was kinda just gonna make an all purpose component that I can put on anything that needs a ground check.

[languid spire]

that will be far from efficient in all cases

[neon ivy]

so I just make a new ground check whenever I need one?

[languid spire]

yes, or copy and change. There is no 'one size fits all' as @wintry quarry said

[hushed hinge]

i have a problem, a code helper did made this changes for like coyote timer and the buffer jump
"Jump buffers are when you press jump before you land but because you haven't touched the ground you don't jump, the buffers fixes that it saves the jump in for a short period letting u jump so its less frustrating,
Same with coyote time that lets u jump after u walked off a platform, like a small window of opportunity"
that is what someone said, but however ever since those things were added, the jumping mechanic haven't been working properly that instead i jump higher instead of normal and i just jump normal instead of higher in my jumping frog power-up, you even jump on the walls. i don't know why since someone did made the coyote timer and buffer timer
https://gdl.space/tupijoxuxa.cs

[languid spire]

That is a lot of code with not one single Debug.Log statement in it. So how do you know what it is doing?

[hushed hinge]

https://gdl.space/dowalixowe.cs then i choose out of the things that have to do with jumping from the script

[languid spire]

you miss my point.
You have no idea if any of the code is being executed
You do not know what paths are being taken through the code
You do not know the affect that your variables have on the output

[rough orbit]

In the below, I want there to be a short delay before myRigidbody.useGravity = true; comes into effect. What would be a good way to do that?

    private void OnCollisionEnter(Collision collision)
    {
        if (collision.gameObject.tag == "Player")
        {
            GetComponent<MeshRenderer>().material.color = Color.red;
            myRigidbody.useGravity = true;
        } 
        else
        {
                myRigidbody.useGravity = false;
        }
    }

[languid spire]

Coroutine

[hushed hinge]

i did say that someone made this whole coyotetimer and buffertimer code adding in. even though everything works barely, it's just that the jumping frog and the normal jumping are just switched

[wintry quarry]

I mean feel free to do so if you find it helpful.

Just because it doesn't solve all cases doesn't mean it won't solve most of yours

[neon ivy]

[safe root]

How do I solve this problem. I solved it once but completely forgot how. I'm not sure if there was a command for it or not

[cosmic dagger]

that definitely sounds hard to solve . . .

[safe root]

I don't think I can send photos

It's the .Net Core SDK not being found so it doesn't show any problems with my code but in Unity I have a problem

[languid spire]

if you solved it once then google it

[safe root]

I solved it through one of these discords

[hushed hinge]

did some debugging and seems like the jump and doublejump does at the same time, the same for the jumping frog the charge, jump and doublejump at the same time. even though it still looks like they both have switched roles

[rustic maple]

why does my fps controller player keep falling through my terrain? i tried adding multiple colliders to both but nothing works, it also falls through a plane

[wintry quarry]

Without seeing any details about your setup...

¯_(ツ)_/¯

[rustic maple]

alr one sec

[wintry quarry]

You would have to show us how its set up, the code, etc.

[rustic maple]

i got these 2

and this the script i used

https://www.sharpcoderblog.com/blog/unity-3d-fps-controller

can you share your actual script?

I don't see anything odd about the script from the tutorial, o the question is:

• Did you change anything, or not copy something correctly?
• Do you have other scripts
• Is your terrain weird somehow

[rustic maple]

https://paste.ofcode.org/384HJ2QrYPfzupjp5BjiRAF

[rustic maple]

its the same as the website tho so

[wintry quarry]

yeah it's the same

can you show your hierarchy

[rustic maple]

it is a terrain from an asset to maybe it has to do something with that, that maybe i didnt use it the right way

[wintry quarry]

certainly don't add any other colliders

[rustic maple]

the only collider is the terrain collider on the terrain itself

i removed the capsule collider from the player

[wintry quarry]

what is on the "Player" object ?

[wintry quarry]

Can you show Edit -> Project Settings -> Physics and show the layer interaction matrix?

[rustic maple]

you mean this?

[wintry quarry]

I'm not seeing anything wrong

Can you try with a basic/empty terrain and see hwat happens?

[rough orbit]

Thanks! The script is on every tile on this chess board. The player moves 1 tile at a time and currently every tile is gonna fall OnCollision. Any idea how I would make it random which tile is gonna fall? I'm thinking 30% chance.

Script again:

    private void OnCollisionEnter(Collision collision)
    {
        if (collision.gameObject.tag == "Player")
        {
            GetComponent<MeshRenderer>().material.color = Color.red;
            myRigidbody.useGravity = true;
        } 
        else
        {
                myRigidbody.useGravity = false;
        }
    }

[wintry quarry]

if (Random.value < 0.3f) Fall();```

[languid spire]

Oddly, I see no Coroutine usage there

[rough orbit]

it's there but cant post it for some reason

[languid spire]

you can also use if (Random.Range(0,3) == 0) { }

[languid spire]

perfect

[rustic maple]

the player also falls through the basic terrain

[wintry quarry]

Can you show the scene, with the collider gizmos visible?

is the player starting above the terrain?

[rustic maple]

it definitely is

[outer wigeon]

Thats the capsule but cant see the actual collider it should be a green wireframe

[wintry quarry]

You're not showing the collider gizmo here

It's probably underneath

[outer wigeon]

you should send a pic that looks like that

@rustic maple

and make sure is enabled

[rustic maple]

my capsule doenst have a capsule collider becuase the tutorial said i had to remove

[outer wigeon]

I suspect we are about to solve a lot of those player falling through the terrain issues then

[wintry quarry]

It has a CharacterController

which is a capsule shaped collider

And which has a green gizmo just like the one shown in the screenshot above

check underneath the terrain

i bet you'll find it there

[outer wigeon]

It is definitely just misplaced then

[wintry quarry]

I would also highly recommend setting this to "Pivot"

The Center setting can be very confusing and disorienting

pivot shows where the object actually "is"

[rich adder]

there are only few specific instances..
Eg Want to rotate a group of objects around a point.. Use Center instead.. but those are very few cases, most times you will use Pivot

[rustic maple]

my character controller gizmo is not showing green like the picture

[rich adder]

show us you have gizmos enabled

#💻┃code-beginner message

[rustic maple]

ooooh wait

i think it has something to do with this

[rich adder]

so basically what Praetor said lol

[rustic maple]

thats when i start the game

[rich adder]

also if thats the CC it should be on the root object, only GFX should be child

[rustic maple]

when in edit mode the capsule is on the ground and the character controller is floating in the sky

[rich adder]

because your child positioning is off..

reset it

just to be clear the CC should not be on the child

[rustic maple]

it is on the parent

[rich adder]

ok so you clearly have 2 objects

which one is the child then

the "mesh" ? if so it should be ok just reset pos

[dusky nest]

how do i do this? the script was given to me by the assignment, but the counter integer was added by me as per instructions. i'm not sure if i even added counter correctly.

using UnityEngine;
using System.Collections;

public class Forces : MonoBehaviour
{
    int counter = 0;
    public float speed;
    // Use this for initialization
    void Start()
    {
         
    }

    // Update is called once per frame
    void Update()
    {

    }
    void FixedUpdate()
    {
        float hor = Input.GetAxis("Horizontal");
        float ver = Input.GetAxis("Vertical");
             
        Vector3 move = new Vector3(hor, 0.0f, ver);
        GetComponent<Rigidbody>().AddForce(move * speed * Time.deltaTime);
        counter++;
    }
}

[dusky nest]

also tysm!

[zinc seal]

first day progress learning unity (all the code is stolen 😂)

[rich adder]

well if its only when the ball moves then you should put it only if the velocity is anove a threshold

also Time.deltaTime is wrong on AddForce, we dont add that since addForce already moves the rigidbody with Physics loop. And you're correctly using FixedUpdate so its fine. Just remove Time.deltaTime

[zinc seal]

how do I start learning C# for unity whenever I find a guide I end up just copying the code without really knowing what it does or how it works

[rich adder]

check pins in the channel

[teal viper]

Stop just copying it and start reading it and trying to understand it.

[rich adder]

the problem with this is you're catapulting yourself right away into some complex stuff, you have to build from the ground up .

[zinc seal]

[zinc seal]

well I was inspired by some game I found on roblox and really wanted to recreate it thats why I started

[rich adder]

learn how to store a name into a string and print it back, etc

[rich adder]

inspirations are great for starting out a field, now that it peeked your interest, start finding out all the necessary lego pieces you need, you will build your own megastructures in no time

[dusky nest]

Time.deltaTime was created by my instructor so im not sure if i should touch that. i dont know what a threshold is in this sorry. i was thrown into this assignment without much of a tutorial

[rich adder]

your instructor is an idiot

[dusky nest]

yeah he forgot about his online class 😭

[rich adder]

not a real teacher, and has no clue how Unity works

[zinc seal]

I wish freecodecamp had courses for game development, their courses are just amazing for beginning.

[dusky nest]

and ofc his in-person class is on the further campus

[eternal needle]

GetComponent in fixed update too... what a leader

[rich adder]

big brain moves

i bet didnt even explain what velocity of a rigidbody is and how to use it to calculate a magnitude for speed of movement

which is basically what ur assignments requires

[dusky nest]

nope 😭 and we're expected to create a game next week

[rich adder]

"move the counter value only when its moving"
yours is counting every physics frames even not moving

[dusky nest]

lmaao

[rich adder]

You need the magnitude of you rigidbody, if its above a threshold , start counting

[zinc seal]

what course would you guys recommend for unity? (preferably free lol)

[rich adder]

mate I told you check out the pins lol

particularly do Essentials Pathway and then Junior Programming one

[zinc seal]

I know but theres like 3 courses and I get distracted with choice

[rich adder]

as I said, should do Essentials pathway, then Junior Programmer and then this one https://learn.unity.com/project/beginner-gameplay-scripting

the last link is the one I first learned unity with

they had no pathways when i started :\ consider yourself lucky

[zinc seal]

alright ill spend today (or however long it takes) working on the essentials pathway

[hushed hinge]

i am talkign with someone who made this coding but i am also waiting for them after the exams to see what is wrong with it

[steep rose]

it will be as long as how fast you learn

[zinc seal]

thanks for the help

[rich adder]

goodluck 🫡

[steep rose]

i never used unity learn to learn i kinda just winged it, dont do what i did

[zinc seal]

I did pretty well last time I took a coding course but that was html and css so its not exactly rocket science

[steep rose]

its a bad habit 😅

[zinc seal]

worst part of unity is waiting for a project to load 😭

[rich adder]

great now you're using a REAL language

[zinc seal]

making my ssd feel like a hard drive

[steep rose]

wait till you get to C++

or C

thats where the fun happens

[rich adder]

mehh stick to c#

if you value your sanity , no reason to ever touch C/C++

embedded system

[steep rose]

I personally dont so i will use it lmao, scratch that I do, i just like C++ for learning game making, etc

[zinc seal]

if I learn any other language besides C# it will be rust

[rich adder]

its good but very niche usecases atm

[zinc seal]

its the future! (or at least thats what everybody and their grandmother is saying)

[steep rose]

who says that

[rich adder]

just like web assembly supposed to replace javascript...yet here we are...

[zinc seal]

You'd be surprised

its like a cult from what i've seen

[steep rose]

they are a silent one then

[zinc seal]

not around the right people I guess

[teal viper]

Learning C++ would benefit you a lot more than rust imho

[zinc seal]

I heard more about it when I was big into linux, much less now, so probably just depends what community you're in.

[rich adder]

tru dat

[steep rose]

dilch knows what he is talking about

[rich adder]

but if ur coming from html/css you're better off just going to c# and not deal with memory management so early on or you will probably quit

[steep rose]

yeah C# is way easier than C or C++

[rich adder]

c# can pretty much do it all and its easy

[steep rose]

but C++ is so so so so fast

but it will make you go insane (if you dont know what you are doing)

[rich adder]

irrelevant to unity

[teal viper]

The gap is not as big as you might think

[steep rose]

yeah true

[teal viper]

Code architecture and optimization techniques matter a lot more than the language you're using.

[rich adder]

wait till you have to do some c# marshalling to talk to C code

[steep rose]

hopefully i wont have to do that 😅

[rich adder]

fun times

[rich adder]

its a fun little project, try sending some structured C/C++ data to your C# application, you're in for some funsies

but yeah going a bit #offtopic from unity before I get the 👢

My gameobjects enums keep resetting to the first value ? is this a bug , never had this happen before ?
it happens at random times

and only this specific enum?

[brave compass]

Are you overriding the integer value of any of the enum values, or just letting them be the default?

[rich adder]

no here is my entire class
https://gdl.space/zoriqusuku.cpp

ChessPieceColors one is fine though

[brave compass]

Do you have any third party assets that override the default editor, like Odin Inspector or Naughty Attributes?

[rich adder]

none

[polar acorn]

It's probably an editor script of some sort. Maybe it's a race condition? I wonder if that OnValidate is causing some sort of inversion of order, where something else tries to write the piece type before it actually reads it?

[rich adder]

I dont use many assets here but will check, its weird that only that one is basically borked.
that OnValidate was acting strange for me before it wasn't catching GetComponent so it could be something with it. I'll remove it and see what happens without

[steep rose]

try setting the enum on start

the ondrawgizmos stuff now this?

[rich adder]

thats not very modular 😛

that would mean All the pieces still have the same type

[steep rose]

i mean you could do

public enum chesstype{
//whatever
}

private enum chesstypes{
//samestuff
}

private void start(){
    chesstypes = chesstype;
}

i know its janky

but it may work

[rich adder]

not sure I understand

All my pieces need to bet set in inspector as different chesspieces

I think its working now though, I just remade the Enum as something else..I think something got borked in the serialization process..

so far hasn't changed 🤞

[steep rose]

well yeah so you have an enum as your "selector" then a private enum and you set the private enum to the "selector" type and just use the private enum for everything in your scripts

if it just started to randomly work then you dont need to do this 😂

[lilac moth]

Is this text channel where we would ask for help?

How can I fix it?

[rich adder]

Keep UI with you on DDOL

make canvas child of the object with DDOL and Score Manager on it

or find it at runtime every scene change

[formal hill]

So make canvas the child of GameManager?

[rich adder]

that would be the easiest

not as clean but will do

[formal hill]

New problem😅

[lilac moth]

Im in Unity3d and I have a rotating obstacle that I want to collide with the player and push them. The obstacle collides properly and pushes the player when it moves slow, but the player phases through the obstacle when it moves fast.

The player and rotating object have colliders and rigid bodies using continuous collision detection, yet faster rotation of the obstacle makes the player phase through it. The obstacle is using rigidbody.moverotation (I used https://docs.unity3d.com/ScriptReference/Rigidbody.MoveRotation.html). The player moves with playerRb.velocity = new Vector3(speed * horizontalInput, 0, speed * verticalInput);

[rich adder]

how do you normally hide the retry screen ?

[wintry quarry]

Set the collision detection mode on the rotating object to continuous speculative or whatever it's called

[lilac moth]

tried that as well

[formal hill]

It's already disabled when the game starts

[wintry quarry]

How fast of a rotation are we talking ? There are limits

And there are limits to what the engine can properly compute in terms of rotational collision

[rich adder]

oh okay because remember anything in DDOL will not run Start or Awake the time the scene reset, since they are technically still Awake/Start since creation

perhaps you should explicitly hide the retry scene on click

[formal hill]

Ok so when the player presses the retry button I should disable the Death screen?

[rich adder]

indeed.
ideally you eventually want to have a menu/UI manager of sorts for these 😅

[wintry quarry]

And show the inspector for this object?

[formal hill]

Yeah, well that's a bit too advanced for me at this moment

[rich adder]

start simple.
for example, just a method that deals with HideRestryScreen() or ToggleRetryScreen(bool value)

[wintry quarry]

Seems fine to me. Perhaps try decreasing your fixed timestep

[formal hill]

I'll most likely do that at some point. (If I'm not too lazy to😅 )

[rich adder]

you already have a "Score/Game Manager" the concept is the same ( a centralized script that deals with all its related functions/ duties)

[formal hill]

The Score system works now but, the bloom effect doesnt affect it after resetting it.

So the score text is no longer glowing or anything

[rich adder]

did you also bring with you the post processing / PP Volume

[formal hill]

Wait

[formal hill]

I feel dumb now😭

[rich adder]

DDOL is convenient but tricky too

[wet raptor]

I am having an issue where my PlayerInputActions. Using the input system is throwing an error.
What have I done wrong?

[formal hill]

Yeah... it still doesnt get affected by bloom even tho Global PP is a child object of GameManager

[wet raptor]

Error code is 'PlayerInputActions': member names cannot be the same as their enclosing typeCS0542

[polar acorn]

You can't have an action map with the same name as the input object

[short hazel]

You have an action map named the same as the asset itself. You cannot do that

[rich adder]

is it still enabled after reset scene?

[wet raptor]

As in one of these needs to be a different name?

[polar acorn]

Check the action maps in the object

[formal hill]

It affects everything, but the score

So I think yes

Yes it's still enabled after the reset

[rich adder]

I think its your camera, are you bringing the same camera with you

this is one of the things I deslike about making everything DDOL lol

[formal hill]

Now it pretty much works but it says

MissingReferenceException: The variable GameOver of GameManager doesn't exist anymore.
You probably need to reassign the GameOver variable of the 'GameManager' script in the inspector.
GameManager.GameOverScreen () (at Assets/Scripts/GameManager.cs:24)
Enemy.OnCollisionEnter2D (UnityEngine.Collision2D collision) (at Assets/Scripts/Enemy.cs:87)

And both the scripts that the error is about are turning on the death screen

[wintry quarry]

Probably a DDOL object trying to keep a reference to something in the scene, which is destroyed when you reload the scene

Specifically whatever the GameOver variable is referencing

[formal hill]

Yeah, but I dont know what

[wintry quarry]

This...

[formal hill]

It's referencing a panel to the whole game over screen

[wintry quarry]

Ok, that panel is being destroyed

And then you're trying to use it after it's destroyed

[rich adder]

remember anything in the scene that references the DDOL objects will not longer have the same reference when you load (ddol they will go in their own scene called DontDestroyOnLoad)

[formal hill]

It's not supposed to get destroyed I've only made it to be disabled

[rich adder]

objects get destroyed when switching scene

[formal hill]

How can I make things to be in the dont destroy on load

[rich adder]

once you make something DDOL if you want anything from another scene to access it, it must be done with something like a Singleton , Or some type of GetComponent/DI

[rich adder]

dont start making everything in the DDOL , this is one of the many pitfalls as beginner

learn how to properly get the references when needed

[rich adder]

first breakdown, why does a scene object need reference to GameOver display

[formal hill]

So they can be restarted?

[rich adder]

from where?

your DDOL scripts should be only ones handling it

why does Enemy have it

Enemies should not care about Gameover, or UI or any of that

[formal hill]

I don't have a specific ddol script. I have a scenemanager the SceneManager references the death screen to not be destroyed on load

[formal hill]

They dont

[rich adder]

so which one is turning on the death screen?

[formal hill]

Scenemanager

[rich adder]

can you show the function Enemy.OnCollisionEnter2D

[formal hill]

private void OnCollisionEnter2D(Collision2D collision)
{
    if (collision.gameObject.CompareTag("Bullet")) 
    {

        Vector2 knockbackDirection = (transform.position - collision.transform.position).normalized;

        rb.AddForce(knockbackDirection * knockbackForce, ForceMode2D.Impulse);
    }

    if (collision.gameObject.CompareTag("Player") && !isDead)
    {
        isDead = true;
        ParticleSystem playerEffect = Instantiate(playerDeathEffect, transform.position, Quaternion.identity);
        Destroy(collision.gameObject);

        gameManager.GameOverScreen();
    }```

[rich adder]

so put scenemanager on the DDOL stack since its a manager

as long its not a scene gameplay object , this is fine for a manager script

[rich adder]

if GameManager is ddol script gameManager.GameOverScreen(); is breaking

you're referencing an instance which no longer belongs to that scene

at very least it would be GameManager.Instance.GameOverScreen();

personally though I would opt for an event your enemies invoke, then its up to your game manager how to handle it

GameManager captures all scene enemies on scene load, then subscribes to such event

now your enemies would do their thing without caring about handling game states..

[formal hill]

"Instance" gives an error

Severity Code Description Project File Line Suppression State Details
Error (active) CS0117 'GameManager' does not contain a definition for 'Instance' Assembly-CSharp F:\Unity projects and backups\Projects\Shooter Footer Looter\Assets\Scripts\Enemy.cs 87

[rich adder]

you realize it was an example right

assuming you were to make GameManager a proper Singleton instance

[formal hill]

Oh

What am I supposed to do to fix this??

[rich adder]

look at least your ScoreManager has one but its lowercase i

[rich adder]

I literally just explained two ways you can fix this lol

what part confuses you

[formal hill]

Like the whole thing

[rich adder]

anything you link inside the inspector that is now on DDOL will BREAK

including the GameManager

[neon ivy]

for an open world, how do I differentiate between something walkable and something climbable without tags and layers cuz then it always has to be different objects

[formal hill]

Yeah

[rich adder]

do you know why it has instance as static and then assign instance = this
