first person camera smoothing

[verbal dome]

Oh, so rotation smoothing, not position smoothing?

Same suggestions apply nonetheless

For the Y angle you want to use the Mathf.LerpAngle/SmoothDampAngle variants instead so it wraps around

[pure kite]

it already wraps around I think? my current code is:```cs
void LateUpdate()
{
Cursor.lockState = CursorLockMode.Locked;
mouseVector = controls.Player.Look.ReadValue<Vector2>() * sens;

    look.y = Mathf.Clamp(look.y - mouseVector.y, -85f, 85f);
    look.x = Mathf.Lerp(look.x, mouseVector.x + look.x, 0.1f);

    transform.localEulerAngles = new Vector3(look.y, look.x, cameraTilt);
    mouseVector = Vector2.zero;
}```

[verbal dome]

Oh yeah, still though I'd keep it in the (-180..180) or (0..360) range to avoid precision issues if the number gets too large

[pure kite]

oh true

[verbal dome]

The player would need to spin around quite a lot for that, but better to be safe

Anyway see boxfriend's link for fixing the lerp

[dull slate]

I'm working on the Roll-A-Ball Game Tutorial and stumped on the "Apply Force to the Player" section. I followed the instructions and my OnMove function is greyed out. I know its not being called but just dont understand what step I missed.

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

public class PlayerController : MonoBehaviour
{
    private Rigidbody rb;
    private float movementX;
    private float movementY;

    void Start()
    {
        rb = GetComponent <Rigidbody>();
    }
    void OnMove (InputValue movementValue)
    {
        Vector2 movementVector = movementValue.Get<Vector2>();

        movementX = movementVector.x;
        movementY = movementVector.y;
    }

    private void FixedUpdate()
    {
        Vector3 movement = new Vector3(movementX, 0.0f, movementY);
        rb.AddForce(movement); 
    }
  
}```

[pure kite]

Yeah changed it to look.x = Mathf.Lerp(look.x, mouseVector.x + look.x, Mathf.Exp(-0.01f * Time.deltaTime)); but it doesn't lerp? I tried changing the decay value to very large and very small numbers which made no difference

[verbal dome]

I don't see you using the decay value at all

There's just a constant -0.01f

[pure kite]

oh wait

what inputs do I put for decay

[verbal dome]

The page explains it all.

See the text under the Improvements code example

[pure kite]

I'm not great at c#, do I put the "static float" in update? idk how to use that

[verbal dome]

You could put it inside Update, that would make it a local function and it would be available only inside Update

[rich adder]

is the script on this object with PlayerInput? being grayed out its fine in this case cause SendMessages uses different way to call it

[verbal dome]

Better keep it separate in a class, it could be your current class or a different static class that contains helper methods

[pure kite]

oh ok wasn't sure if it had to be updated for it to work

[verbal dome]

That's not how local functions work, so yeah try to avoid them for now as a beginner

[dull slate]

I slapped it on there now. The tutorial didn't mention it so I was unsure

Ball still doesnt move though 🤔

[rich adder]

should be working, put a Debug.Log inside the method to be certain is called

[dull slate]

Tried that and nothing

[pure kite]

am I using this right? it doesn't seem to be doing much lerp-ing, kinda just changes the sensitivity on the x axis cs static float ExponentialDecay(float value, float target, float decay, float deltaTime) => Mathf.Lerp(value, target, Mathf.Exp(-decay * deltaTime)); look.y = Mathf.Clamp(look.y - mouseVector.y, -85f, 85f); look.x = ExponentialDecay(look.x, look.x + mouseVector.x, 10f, Time.deltaTime);

[rich adder]

show the console in playmode when you press keys

[verbal dome]

Try different decay values, you are currently just using 10f

Make a variable you can tweak in the inspector

[dull slate]

nvm works now lol! thank you!

[rich adder]

oh okay, cause the rigidbody seemed to be missing you probably had null ref

[pure kite]

yeah I tried multiple values 0.001-1000 and all it did was change the speed there wasn't any lerp

[dull slate]

Weird that the tutorial doesn't tell us to attach the script to the object

[verbal dome]

Show the full script, use a paste site

[rich adder]

the SendMessages uses some type of reflection " looking by name" so its private and naturally ide doesn't know if its called

[rich adder]

bad tutorial ?

[pure kite]

https://pastebin.com/mpvB1qJt

[dull slate]

Its this one https://learn.unity.com/tutorial/moving-the-player?uv=2022.3&projectId=5f158f1bedbc2a0020e51f0d#650b1ec9edbc2a263aa43ebd

Not sure if I should just do pathways instead

[rich adder]

you missed a step

[dull slate]

welp I guess I'm stupid lol

thank you again!

[verbal dome]

Were you changing the value of decaySpeed in the inspector or in the script?

[pure kite]

script, but I updated it every time I know things don't update like that in play mode

[rich adder]

@dull slate it helps most of the times if you read through/watch all steps a couple times without touching unity, then after starting to copy / following in Unity.

[verbal dome]

The value you define in the script is only the default value when you add the script for the first time, or reset it

Just tweak it in the inspector, that's the actual value that unity has serialized (saved) on the object

[pure kite]

I edited in script before I had a variable

and I added a public variable to change it but it's doing the same thing

[verbal dome]

Not sure then

[frigid sequoia]

What is the index value of scene that is not on the buildIndex? Null?

Can I get something to happen if a scene is not on the build index?

Like... this scene is a testing ground not meant to appear on build so when loading it you can skip these steps?

[sour fulcrum]

scene needs a build index

otherwise your not loading it

afaik

SceneManager converts the string name into index

[frigid sequoia]

Not if I start on that scene on the editor

[slate glade]

I need som help with this thing I’m trying to make, and I can’t seem to find any resources online about it.
I want to make a game launcher for external, non-unity non-steam .exes where you can select a game by clicking on an image, it gives you a little description and you hit the launch button to play the game. I made a little mock-up for it but I’m not sure where to start.

[frigid sequoia]

Pretty sure it still applies the on load effects

[sour fulcrum]

Well the answer then is that it has no build index

(Which isn’t it being null)

[frigid sequoia]

Then what the heck is it?

Does it return a missing reference error if I try to get the index?

[sour fulcrum]

It’s not acknowledged by any runtime available scene functions

[teal viper]

Maybe -1. Test and see for yourself

[sour fulcrum]

-1 is ddol and/or hideanddontsave iirc

Pretty sure it’s one of them

[teal viper]

The docs explain it all actually

When unsure, read the docs first.

[frigid sequoia]

Where?

Ouh, on Scene.buildIndex, I was looking on the parameters of LoadScene

[slate glade]

if anyone could send some resources or sites to help that would be great

[sour fulcrum]

There’s nothing directly to really link you to be honest

You’ll be looking for resources for the different aspects of this

how ui works, how to open an exe in unity etc

[frigid sequoia]

Yeah, you pretty much asked for a whole app lol

[slate glade]

fair

[toxic herald]

@rich adder I FUCKING DID IT!

Now the video recording is working

i spent the whole day trying to figure it out, coding and refacturing, but finally did it

[calm adder]

What?

[calm adder]

Sorry but i dont remembe helping you with something

[frigid sequoia]

Mmmm... What kinds of methods can I call from an UI dropdown on value changed?

It lets me pick methods that need an int as parameter so I guess the value it sends is the option index????

Cause I am kinda using an enum, and would love to be able to pass that as a parameter for the method

[toxic herald]

LMAO it was @rich adder , i chosed the wrong person when i was hovering through the @

[teal viper]

Only methods that take primitive type parameters. And there's a limitation on the number of parameters too iirc.
You could use an int and cast it to your enum later on.

[frigid sequoia]

I did that, but I was kinda hoping I could call a method with more than one primitive value

Like an int and 2 bools

But doesn't seem to allow it

I guess I have to split it on 4 methods then lol

This seems like a lot of jumps??? Am I doing this way more complex than it should or it is fine?

[teal viper]

You can add a "button handler" sort of script to your button, assign whatever properties/fields you want on it and call a no param method from your button. Then inside the method in the script call whatever the final destination is with whatever parameters you want.

[teal viper]

It's hard to read.

You should make it more generic like I suggested.

[frigid sequoia]

Yeah, the thing is this is technically 4 different dropdowns that are gonna do basically the same thing of changing an enum variable value on a script, just that the variable they are changing is different for each even tho the enum used is the same

I was hoping I could sort it out with just one method

[teal viper]

You can. Do it with a proxy script as I suggested.

The button doesn't need to know anything about your project.

But your own script can.

[frigid sequoia]

I don't quite get it. How can I know where I want the no param method to continue if I have no params added to it to tell??

[teal viper]

You define the parameters on your proxy script.

[eternal needle]

did you end up using ffmpeg? just curious cause the feature is definitely interesting

[teal viper]

public class ButtonHandler: MonoBehaviour 
{
    [SerializeField] ParamTypeA myParamA;
    [SerializeField] ParamTypeB myParamB;
    ///Etc...

    public void OnClick()
    {
        //Call a method, event or whatever.
        MyEvent(myParamA, myParamB);
    }
}

[frigid sequoia]

That, pretty much would just make them statics? I can... already do that?

Ouh, you are saying I could change the params like when you click on the dropdown to know what is that I am changing?

[teal viper]

You can change them dynamically if you want. Point is, it allows you to bypass the limitation of the unity button.

[frigid sequoia]

I see

Seems useful, but probably even messier on this case

[toxic herald]

Yess, then I combined it with another thing to get the audio and then merged it all together

[toxic herald]

But yeah, it makes quite a difference while recording, makes your fps go down like 15% when you're recording with the camera

I just wanna know if it will impact when the game gets the multiplayer, but I assume, since it's just recording from your screen, it will not break other people fps when you're recording

Maybe if you're the host a little bit

[eternal needle]

its not like you'd be using cpu power if someone elses computer was doing the work. but if u make a multiplayer game, it should be multiplayer from teh start

[toxic herald]

A quick video of me testing it(also realizing that I already got the ghost activities in the game though bug LMAO)

[toxic herald]

Yes, but for now I'm just coding the mechanics

I'm on 3rd week of development actually

Only problem I get using it, is that it can only be done through the main camera, so even that I'm recording using the camera, you will see the player camera at the video

But maybe I could make it an head camera

[keen owl]

looks neat, good work!

[toxic herald]

Thanks!

[rich adder]

awesome what did you end up using ?

oh nvm just scrolled up

maybe knowing more could figure out if its something that can be offset into Jobs / async workload ?

[frigid sequoia]

How can I.... tell if a player is clicking inside the UI?

That's pretty abstract. Let me explain. I got a system where if the player clicks on an entity, it is selected and it's automatically deselected if it clicks anywhere else. When the entity is selected it shows an UI where the player can set a bunch of things. I want to not deselect the entity when clicking over there

How can I exactly tell when the player is doing that? With colliders seems like a total mess

[sour fulcrum]

Usually unity has some built in solutions to this but generally you just check if the mouse pos is inside the rect of the ui element

and then if they are clicking while in the rect then

there's ways you could handle checking for all that depending on your vibe

[keen owl]

You can just use an OnPointerOverUI (or any method you want) of a type bool and check if you are over the UI and if not, apply the deselection logic in some conditional. Also, you can’t use colliders with graphic raycaster elements

[frigid sequoia]

This SEEMS to work

But it's being a bit janky

Not sure if for UI elements I should be including camera or not

Seems worse with camera

[echo lintel]

wait that's actually so cool

for mac is VScode better than Jetbrains as an IDE for a complete beginner

lowkey im gonna try jetbrains bc i have no idea what to expect anyways

[keen owl]

What do you mean include camera? Your implementation looks correct the way it is right now

[frigid sequoia]

Camera.main

[keen owl]

How would that help with your problem?

[rare basin]

@frigid sequoia use EventSystem.current.IsPointerOverGameObject()

it returns true if the pointer is over UI content from either uGUI or UI toolkit

this is a code related channel

im really sorry i was sleepy and completely forgot i asked a question until i woke up today

ill look more into flyweight in unity then to see where i could include it

[spiral glen]

the dotproduct of a quaternion is just
(q1w)(q2w)+(q1x)(q2x)+(q1y)(q2y)+(q1z)(q2z)
right?

[north kiln]

Luckily there's an API for that

[spiral glen]

hypothetically if the API didn't exist would I be correct?

cuz google sucks

[north kiln]

Not sure why the API wouldn't exist

[spiral glen]

[chrome apex]

So is slerp not doable in update? Should I use a coroutine or call a method with a while loop instead?

[rare basin]

huh, it's doable in update just fine

[chrome apex]

Sorry, I should have been more spwcific. I need to generate a target rotation and THAT should be outside of update. The slerp itself should work in update

[north kiln]

That is just as vague

Slerp is just a math function, you can call it from anywhere and it will "work"

[chrome apex]

I have an object which I don't want to be completely still. I need to add micro rotations that don't stray far from the original rotation

That part is fine

But do I just call a method with while (slerp in progress), then after finished, flips a bool

[rare basin]

why not just use DOTween

[chrome apex]

Then I have a if(finished) in update ehich calls the method

[rare basin]

and .OnCompleted() etc

[chrome apex]

Cause idk how to do the entire thing in update

[rare basin]

google DOTween

and DORotate()

DORotate(Vector3 to, float duration, RotateMode mode)

and OnCompleted()

[chrome apex]

Ok if I don't wanna import dotween for this one thinf

Is the way I described ok?

[grand snow]

nothing wrong with rotating yourself via Update or a coroutine or async func

[rare basin]

try it and see lol

[chrome apex]

Wait I think I figured out a nice solution

I call a method which just does float mytime = Time.time + somenumber

And in uodate I have if (Time.time >= mytime)

I think that works

Wait no, time will keep getting added, that needs to be a coroutine...

[rare basin]

what are you even trying to do

it's still not clear

[grand snow]

you can store the start time, each update you do Time.time - startTime to get the relative time from the start.
Or you start with a float at 0, add Time.deltaTime each Update and use that to do the change.

[raw smelt]

Hi i have some performance issues can you give me some tips how make game more optimize
2D kind of TowerDefens
many enamy + bullets
I already implementen Enamy and bullets Pool its helps but not enough
I am pretty sure that i should easy manage something like 1000 enamy at screen

Graphisc for now actually not exist XD (everything is just cricle or capsule )
Profiler show that orther + physics 90% of calculation time

[rancid tinsel]

record a video of your game so we know what its like

also are you doing a lot of stuff with physics?

[raw smelt]

for now Video is not needed XD Its just mechanics test and try optimize it
White go into center and you have to kill it fast enough XD

[raw smelt]

just collider to detect "enamy in range"

• bullet hit enamy

[rancid tinsel]

video is needed to see when the lag spikes happen

or is that not the issue?

[raw smelt]

actually just slow down (there is not freez effect )

or the "fps jumps" are not that big

I notice that if i add "weapons" the fps go down faster
maybe its becouse every weapon have colider (to detec enamy in range )

can i somehow disable OnStayTrigger ( i have list of enamy enter into range anyway )

And its slow dows becouse every 2 s enamy respawn and everytime the number or respawned enamy are +1

[rancid tinsel]

are you checking distance for every weapon in update()?

[raw smelt]

not

[rancid tinsel]

it may be this actually

from what i understand it runs every frame

replace it with OnTriggerEnter and OnTriggerExit

[raw smelt]

void OnTriggerEnter2D(Collider2D other)
{
if (other.CompareTag("Respawn"))
{
GameObject enamy = other.gameObject;
fire_controll.add_enamy_in_range(enamy);
}
}

and during updated i check
reload time
then if last target is still alive/active
if not then filter list of enamy (so there will be only active enamy )
and choose random enamy from list

replace it with OnTriggerEnter and OnTriggerExit
i have already OnTriggerEnter2D (becouse 2d)

[rancid tinsel]

can you show the whole script

ITs a little mess XD I will make refactor after optimize basic mechanics (:

• i am begginer in c# and unity

[ivory bobcat]

You may want to consider using the profiler to see what's exactly slowing the application

[raw smelt]

i did phisics + orther
(btw i see potecial bug XD in finding enamy in range XD )

• i can see now that that list can go into infinity
  But still scripts takes like max 5% in profiller

[ivory bobcat]

You can disable the collider but it may do more than just what you're wanting.

[raw smelt]

nah i just afrad that this function is called too many times
for example 400 enamy in range of 20 weapons = 20*400=8000 calls ?

[ivory bobcat]

Use the profiler else that's only an assumption

[raw smelt]

i did use that XD
And physisc + orther are 80% of the calculation time

[ivory bobcat]

You'll need to provide the profiler info to get help with performance. The function cannot be optimized any further as it isn't doing much. You can use non-unity collision detection algorithms if you're needing lots of detection with objects. This isn't really a code issue anymore.
Profiler help would probably get more support in #💻┃unity-talk

[raw smelt]

Dalphat are you bot ?
I already gave profiler info ?

[grand snow]

use deep profiling so you can try to identify what specifically in this function is the most costly operation

also you spelt enemy wrong

[raw smelt]

I see no extra info ):

[grand snow]

there is a big area that shows the fucking calls for the frame

[raw smelt]

English spelling make no sens XD
(but THX )

[raw smelt]

Where is that ?

[polar acorn]

This is the first time you've posted profiler information anywhere on the server. What do you mean you "already gave" it

[rancid tinsel]

he meant that he said he already checked profiler i think

[grand snow]

check my pic. click in the graph to highlight a frame and inspect the timeline OR hierachy below to actually see the calls and profiler info

@raw smelt ^^

[polar acorn]

Just start unfolding menus and looking at stuff. Try to find what corresponds to that big spike from the screenshot

[grand snow]

check where there is a big spike on the graph or where its not giving a good framerate, then check the "main thread" area for the calls.
use hierachy mode as its easier to go down and read everything happening:

16 ms is the goal for 60 fps

you can see my example had 4.3 ms for the cpu this frame (total main thread time) which is very good

[grand snow]

that frame is fine. find another that has a much larger ms time.

e.g. spike on graph that goes past 60 fps to like 30 or 20.

[tranquil forge]

are you entering play mode with both scene tab and game tab open ?

[polar acorn]

Seems like it's resyncing and resimulating rigidbodies that takes up the most time

[polar acorn]

So, what's the code that's rinning during this spike? What's the whole physics situation

[raw smelt]

This Is not a spike actually

Its jsut get slowwer and slower as thee is more object

[grand snow]

well thats good, shows the physics system calculating the contacts is taking way too long

try enabling multi threaded 2d physics if its not already @raw smelt

[raw smelt]

hymm ok how can i do it ? or just ask chat XD ?

[grand snow]

Edit > Project settings > physics 2d > multithreading

if you cant even guess where to find settings like this you need to stop using ai 😐

🧠 use brain to make brain worky

[raw smelt]

Man i use unity 2 days XD
I will not expected that in Project settings
I will expedted that in some Engine Setting or something like that

But thx its helps a bit (:
But still i need something extra

Guys, if I wanted to make a little money with unity, except Fiverr, is there anything else i can do?

[naive pawn]

fiverr competitors?

[polar acorn]

sixerr?

[naive pawn]

anyways not a code question

not sure it really counts as a unity question either

[red igloo]

I'm using the new input system and I was using a character controller but now I want to use a rigid body. This is my script idk if I have done it properly but why does the player spawn underground? and the movement is also locked.

https://paste.ofcode.org/fyCUG7hCdvsFbVq44XrYWw

[verbal dome]

As you can see the pivot of the character is too high

[slender nymph]

so you remember everything i told you in the other channel? did you pay attention to any of that?

[verbal dome]

The child capsule probably at negative y position

Oh its still in Center mode

[red igloo]

yh sorry lol just fix it.
https://paste.ofcode.org/39hqPzxBusszvNqyEUs4FHn

[slender nymph]

now show what happens when you use this code

(and obviously have fixed the other things pointed out)

also keep in mind that the gizmo to move the object will be at the object's transform.position once you set the tool handle to Pivot

[patent plaza]

Guys do you believe for a beginner solo developer can make a game jam next August ?

[red igloo]

It works but there's a stutter when looking around

[verbal dome]

Start by enabling interpolation on the rigidbody

[slender nymph]

and stop breaking its interpolation by rotating its transform

[red igloo]

did that didn't fix it

[slender nymph]

you have to do this as well

[red igloo]

Should I use rb.MoveRotation instead of transform.Rotate?

[slender nymph]

which also should be done in FixedUpdate

[ionic crypt]

hello, maybe kind of a dumb question but is it possible to assign a HDR color to a TextMeshPro text object? I've been poking around and looking up stuff and people seem to suggest it can be done from the color picker directly but i can't see any way to input a HDR color

[red igloo]

what so HandleRotation() called in FixedUpdate aswell?

[slender nymph]

pretty sure you have to set it to RGB 0-1 (or whatever it's called) instead of RGB 0-255 to be able to set an HDR color with rgb

[slender nymph]

yes, all operations on a rigidbody should be performed in time with physics updating

[ionic crypt]

I did try putting in values > 1 with RGB 0-1 but the UI just clamps my value to 1 anyway

[red igloo]

I did that but the stuttering is still there but if I change the Fixed timestep from 0.02 > 0.01 the stutter is still there but its not as noticeable as before but I still don't want that stutter.

[slender nymph]

well then ask in a more relevant channel since this is a code channel 🤷‍♂️
#🔎┃find-a-channel

[ionic crypt]

oops ok thanks

[red igloo]

actually if I call the HandleRotation() in fixedupdate its actually worse?

https://streamable.com/f87zxa

[slender nymph]

are you still rotating the camera in that too? because that you wouldn't want rotating in FixedUpdate, you want that following the rigidbody's interpolation

[red igloo]

yes..

[slender nymph]

obligatory: use cinemachine for camera controls, it will be far better than anything you could write yourself

it also separates the camera controls from your movement code because why should the code that moves the player have any information about the camera

[red igloo]

Can you use cinemachine for first person?

also if I use cinemachine will the stutter still be there?

[slender nymph]

you can use cinemachine for any kind of camera stuff

[slender nymph]

provided you aren't breaking the rigidbody's interpolation and you aren't multiplying your mouse input by deltaTime it shouldn't

[red igloo]

thanks I will take a look. If I wanted to control the cinemachine camera with the mouse should I make a separate script for that and add the camera movement from the from the fpscontroller script?

[slender nymph]

No you won't need that at all because you can tell cinemachine to just directly use the desired input action

[red igloo]

how can I tell cinemachine to just directly use the desired input action?

[polar acorn]

Position and Rotation controls. You should have the option to choose input bindings for them when you set them to anything other than None

Not sure the exact procedure for picking them in Cinemachine 3, I've been stuck on 2.x for compatibility reasons, so the menus are different but it's in there somewhere

[red igloo]

This is just confusing to setup, which ones would I use for an fps? and how would I rotate the camera without scripting it?

[naive pawn]

follow, no?

[teal wind]

Hi guys I am making my first unity game ofc in 2D and I got a bit of a problem with some triangles. can anyone help me pls?

I'll post a screen shot of it

here

[verbal dome]

Is this a code question?

[polar acorn]

Is this a question at all even? What's the issue?

[teal wind]

the traingles aren't on top of the squares

[rancid tinsel]

On the right, change order in layer

[verbal dome]

Read the warnings, btw. ⚠️ You aren't supposed to use a sprite here

[rancid tinsel]

But next time go to the #💻┃unity-talk channel for unity questiond

And here for code questions

[teal wind]

oh ok ty

[polar acorn]

Why should they be

[teal wind]

cuz I want them there

[polar acorn]

Okay but what have you done in order for them to do that

the code doesn't care what you want, but what you've done

[teal wind]

I changed their layers and I added a 6th layer for the triangles

I can't code in C# yet

[polar acorn]

That has nothing at all to do with the render order

[teal wind]

then what should I do?

[polar acorn]

Move them

If you want something closer to the camera, put it closer to the camera

[teal wind]

ok ty

[rancid tinsel]

Isn't this an order in layer thing tho?

Or because they're on different layers its a camera issue?

[polar acorn]

You could, but why bother when you can just move them?

Physical position trumps sorting layer trumps order in layer

[teal wind]

I just realised what have I done wrong

ty guys

[rancid tinsel]

Does that work for UI as well?

[polar acorn]

No, UI is based off of hierarchy order

[rancid tinsel]

Ig order in layer is most useful when the sprite position is important

If i understand it correctly

[polar acorn]

Yes, each level of abstraction is there for when you're forced into a specific value for the others

[verbal dome]

Doesn't seem like the On-Screen Button is meant to be used with a SpriteRenderer anyway

[polar acorn]

Yeah but I'll let them step on that rake when they get to it, I'm just answering the question that was asked first and foremost

[echo lintel]

could someone help me find external tools in find Edit > Preferences on Mac 2022.3 LTS

like to connect your script editor

[polar acorn]

I think it's under the "Unity" menu on mac?

[echo lintel]

THANK YOU ❤️

Could someone explain why objects are stuttering when i walking and move my camera around?

public class FirstPersonLook : MonoBehaviour

    {
        // Get the character from the FirstPersonMovement in parents.
        character = GetComponentInParent<FirstPersonMovement>().transform;
    }

    void Start()
    {
        // Lock the mouse cursor to the game screen.
        Cursor.lockState = CursorLockMode.Locked;
    }

    void Update()

        // Get smooth velocity.
        Vector2 mouseDelta = new Vector2(Input.GetAxisRaw("Mouse X"), Input.GetAxisRaw("Mouse Y"));
        Vector2 rawFrameVelocity = Vector2.Scale(mouseDelta, Vector2.one * sensitivity);
        frameVelocity = Vector2.Lerp(frameVelocity, rawFrameVelocity, 1 / smoothing);
        velocity += frameVelocity;
        velocity.y = Mathf.Clamp(velocity.y, -90, 90);

        // Rotate camera up-down and controller left-right from velocity.

[naive pawn]

have you tried putting your camera movement in LateUpdate?

[gleaming bridge]

Yes, didnt work

its only an issue when im moving aswell, when im in place, it doesnt happen

https://www.youtube.com/watch?v=YtZU0drkFE0&ab_channel=AustinYarger

its very similer to this video

[cosmic quail]

are you using a rigidbody for movement?

[red igloo]

@gleaming bridge if your camera is jittering when looking around this is what I did to fix it

• Used input.getaxisraw instead of input.getaxis
• put them in fixed update
• changed the fixed time step from 0.02 to something lower

[cosmic quail]

the right way to do it is to put input in update, movement in fixedupdate, and camera movement in lateupdate. and enable interpolation on your rigidbody

[naive pawn]

setting velocity can be done in Update

[lunar crater]

Does anyone know how i can move my player on a train without "lagging" a little bit behind in my 2d game? Both use a dynamic Rigidbody2D

[timber tide]

Easiest way is to parent it, but I think the proper way to to distribute the velocity to what you're standing on

Non of that is handled for you so best to look around

[lunar crater]

I tried to parent it, but that didnt work since i had to freeze position of the player

[timber tide]

If the parent is also a rigidbody then that creates another problem of a composite body which I've not really looked into

[dire tartan]

ive been looking around on google but cant find the answer im looking for is there any way to allow the user to input an image from files on their desktop during runtime in code and if so what would i look into to do so?

[verbal dome]

If you use a movement system where you recalculate the player's velocity each frame, you can include (add) the train's velocity to the final velocity of the player

[lunar crater]

Yeah, im using a velocity based movement system, if youd like i can send you the scripts so you can look into it

Or should i just use MovePosition()?

[verbal dome]

Share the code and people can take a look and help if they can

[lunar crater]

[verbal dome]

With 2D rigidbodies, MovePosition really just modifies the velocity

So shouldn't be different, you'd just use it a bit differently

[lunar crater]

Ah i see

[verbal dome]

So yeah first you'd need to detect what dynamic object you are standing on, like the train

And add its velocity to your final velocity

Jumping is gonna be tricky

[lunar crater]

Can i just use a trigger for that?

[verbal dome]

Might wanna control the velocity completely yourself, including y velocity

[timber tide]

Thing with game logic is that usually we don't stay true to physics. Jumping usually does keep that localized velocity because otherwise platformers and stuff would feel awful

[verbal dome]

Yeah but you could also just modify your current ground check to detect the collider it hit

OverlapCircle actually returns a Collider2D, but you are using it as a bool currently

Which works, but doesn't tell you which collider you are on

[grand badger]

resolved?

[grand badger]

You should be reading input in Update() -- not FixedUpdate() -- otherwise you're risking missing input.

[lunar crater]

Oh yeah, might as well do that

[grand badger]

Vector2 moveDir;
bool jumpPressed;

    void Update()
    {
        moveDir.x = Input.GetAxis("Horizontal") * PlayerSpeed;

        if (Input.GetKey(KeyCode.LeftShift))
            moveDir.x *= SprintSpeedMult;

        if (!jumpPressed)
            jumpPressed = Input.GetKeyDown(KeyCode.Space);
    }

// ..and FixedUpdate just consumes those values, then sets `jumpPressed` to `false`.

[lunar crater]

i see i see, thank you!

[tame gate]

I´m terribly sorry to bother, I´m new here, but I only started to learn how to program this year and I´m having problems with my polygon collider 2D. I´m making a small Simon says like game with difficulty levels... The other levels worked fine, but the final level the stars start moving, and I´m having problems keeping them from escaping the cloud they are in. It´s almost as if the script of the stars is ignoring the collider. The cloud collider is marked as trigger, the stars are not. I have a static rigidbody2d on the cloud, and on my game manager there is a movement collider to control the area. I tried asking chat gpt to help me and I´m pretty sure it messed it up even more cause the stars continue getting off the cloud. I´ve redone the colliders several times, reset unity, but I´m becoming a bit desperate. I´m sorry if it is an obvious solution that I didn´t catch.

Please help ;-;

https://paste.mod.gg/basic/viewer/olbubqhprifm/1

https://paste.mod.gg/basic/viewer/olbubqhprifm/2

[naive pawn]

how are you intending the stars to stay in the cloud?

like what's the mechanism you have to do so (that isn't working)

trigger colliders don't really collide

[tame gate]

Well I´m basically using the Physics2D.OverlapPoint in the FloatingStarMover script so that the stars float to a random point inside the collider of thr cloud, and if the point is not inside the collider it should reject it and try another point using OverlapPoint. But it´s apparently not working or I did something wrong with the colliders or overlappoint is failing

I don´t quite know if I overcomplicated it as well

[keen dew]

You've disabled gizmos in the video so that none of the debug draws are visible and haven't selected the cloud object or any of the stars so we can't see the collider boundaries but I suspect that the part that adds the wavy motion with Mathf.Sin can easily put the stars outside the bounds since they don't move in straight lines

It would probably work better if the stars checked the boundaries as they move, instead of just picking a target inside the boundaries

[tame gate]

I´m sorry, I just recorded another video with them selected and with gizmos up. I didn´t quite know how to turn it on. I think I can now see the biggest problem lol

Cloud collider was not lined up with the drawing in play mode. Which I find it odd since it was in the scene.

But I will take the advice of checking boundaries as they move, thank you!

[keen dew]

You can probably fix it just by making the collider smaller

[tame gate]

I´ll try that, thank you!

[prime lodge]

can somebody explain please

[slender nymph]

you're likely using a version of unity before 6 that did not include that name change

Alternatively, you made your own class named Rigidbody

[crystal bridge]

Hello, looking for some help on dialogue boxes (or at least what isn't connecting). The intent is that I have a DialogueManager in the hierarchy assigned the respective script. Each object in my game is meant to be clickable to pull up a dialogue box (like commentary). In this case, I have an object called "Photo" that is assigned the "DialogueTrigger" for a response when clicked and a "Dialouge" script which pull the design layout from the "RhiaDialogueBox" object and its children while having fields within the script components for customization.

Currently I know the object is responding to clicks because completely separate scripts like sound are working fine.

Apologizes. When I click on the Photo object, the dialogue box/words/portrait aren't appearing at all. It is currently set to inactive in the hierarchy (seen in pics above), but I intended for it to appear with the customized features from the fields.

[crystal bridge]

using UnityEngine;

public class DialogueTrigger : MonoBehaviour
{
    private void Update()
    {
        if (Input.GetMouseButtonDown(0)) // Left mouse button
        {
            // Perform a raycast to check if the object was clicked
            RaycastHit2D hit = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(Input.mousePosition), Vector2.zero);

            // If something is hit and it has a Dialogue component, show the dialogue
            if (hit.collider != null)
            {
                Dialogue dialogue = hit.collider.GetComponent<Dialogue>();
                if (dialogue != null)
                {
                    dialogue.ShowDialogue(); // Trigger the dialogue
                }
            }
        }
    }
}

[slender nymph]

is this AI generated code

[crystal bridge]

Yes, I was basing the idea from a YouTube tutorial and trying to have AI help pull things together for my purposes (particularly with clicking as opposed to collision)

https://www.youtube.com/watch?v=DOP_G5bsySA

using UnityEngine;

public class Dialogue : MonoBehaviour
{
    public string dialogueText; // Text to display
    public Texture[] portraitTextures; // Array of character portraits
    public GameObject dialogueBoxPrefab; // Reference to the dialogue box prefab

    public void ShowDialogue()
    {
        DialogueManager.Instance.DisplayDialogue(dialogueText, portraitTextures);
    }
}

[slender nymph]

it is against server rules to not disclose when something is AI generated.
also i don't help with AI generated code so good luck

[timber tide]

Regardless AI or not, if something isn't working then you should have that code fitted with debug.logs

[hidden fossil]

anyone online?]

im getting this warning thing does anyone know what it means?

[rich adder]

seems you destroy something, then try to do other stuff on it after it was destroyed

[hidden fossil]

oh yea also i got this bug again where if i play from the level, it shows me the livesUI and Enemy wave spawner there but if i play it from the main menu the livesUI and enemy wave spawner just disappear

[rich adder]

probably bad code or errors, or both

[hidden fossil]

like let me just film it down rq

oh wait what the

its now fixed?

oh wait no its not fixed yet

[polar acorn]

If anything in your scene is marked as a DDOL and references anything that is not, it won't work. You should have the ephemeral objects reference the DDOLs, not the other way around

[hidden fossil]

oh wait i foudn a way to fix it

since for some reason my level 2 scene isnt loading the pause game and liveui component but level 1 and 3 are loading it so should i just delete level 2 and duplicate level 1 or 3?

[polar acorn]

It should either be a persistent DDOL Singleton that properly deals with extraneous copies of itself, or it should be wholly specific to the scene it's used in.

In both cases there should be an instance of this thing in every scene that could use it

[hidden fossil]

ok so i duplicated level 3 and changed its name to level 2 and its still hapenning?

[polar acorn]

Is it a DDOL Singleton that properly deals with extraneous copies of itself?

[hidden fossil]

no

oh wait i fixed it

i found out the problem

the build profile was using the same scene as level 2 so whenever i duplicated a level and set it to level 2 it would use the same DDOL singleton so i had to delete that level 2 scene in the build profile and make a new one

Hello guys, when I disable this Button.. How Can I activate it again when the game gets game over?

[slender nymph]

set it active from a different object, or use an event that it subscribes to. Update does not run on disabled objects

[errant shore]

thanks brotha

do i enable it with button.enabled = true? because this wont work

[slender nymph]

that only enables the component, is that what you've disabled?

or did you perhaps set the entire gameobject to inactive

[errant shore]

oooh i disabled the whole gameobject

but how do i make it unvisible

[slender nymph]

look at the documentation for GameObject to find out what method might be useful here

[errant shore]

i can only make the writing unvisible and not the button

do not be afraid of making something that turns out horribly

[polar acorn]

Is it Unity related

[spiral glen]

if you pray enough

[polar acorn]

Then I guess it's off topic

[eternal needle]

what do you mean "why the Z one is not that smooth"? its really hard to tell what you're referring to from the given info
also not sure if its intended, but two of your vectors are using Vector3, while Z uses transform.forward.
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Transform-forward.html

representing the blue axis of the transform in world space

[earnest wind]

yeah because if it would be vector3.forward it wont work

let me make a video and show

@eternal needle here

you can see when i select it draws the direction, it should work but it just doesnt

[eternal needle]

the code youve shown has nothing about moving objects, so its still not really possible to say much

[earnest wind]

yeah i just shown the part that calculates the direction

if you want i can show the whole function but there is a lot of variables in it

its just basic stuff like this

when started selecting

[eternal needle]

did you debug what the projectedDelta and other values are?

[earnest wind]

when dragging and when done dragging

[eternal needle]

im pretty sure your projection here doesnt make sense, if the transform forward is (0,0,1) and you're comparing it by mouse position which wouldnt have a Z value

Like (X, Y, 0) and (0, 0, Z) should always be 0

[earnest wind]

yeah thats what i was saying, so how should i do it?

[eternal needle]

is there a reason you're projecting the vector in the first place? couldnt you just take the magntiude of how far you moved the mouse and multiply that by the vector

[earnest wind]

wait i can do that 😭

yeah but what about moving it on -x tho? magnitude < 0???

[eternal needle]

well I guess magnitude alone would also have an issue if you want negative values, moving it backwards. But that part can be solved manually
It was also the first thing i thought of, not sure what people do for this otherwise

[earnest wind]

yeah i dont think it would work that well

i mean this works but not in all cases, when camera is rotated the other way its different

also here is debug

when changing x

when changing y

and when changing z

[eternal needle]

it'd probably make more sense if you got the world space location. Did you look up any tutorial for doing this? Just quickly skimming through and a few of them seem to use world space

[eternal needle]

and yes because of what i said above about the vector projection

[earnest wind]

thats what i was previously using but it was off by a lot, it wasnt on the same plane as the x,y or z

im gonna try a different method and see if it works tho

wait i can show you how it was yesterday

[eternal needle]

you should probably follow tutorials instead of randomly trying methods if you aren't familiar with vector math. Getting the world space will probably be the best especially with your problem above of when the camera is rotated

[earnest wind]

i dont follow tutorials 😎 ok i will but let me just try 1 method xD

yeah okay it doesnt work, i will go and learn

also thanks

[eternal needle]

🤷‍♂️ im not forcing you to not try it, but you'll probably see the usual advice will be go learn to debug for stuff like this anyways

the first thing you shouldve seen is that the vector is 0. Asking why the vector is 0 is a lot better if you havent yet learned how to calculate vector projection by hand

[earnest wind]

yeah im kinda new to this vector calculation stuff, not used to this

[eternal needle]

i usually have a lots of Debug.DrawRay around to visualize if things are complicated

its not really easy imo visualizing vector projection either, not that you need it here anyways

[acoustic belfry]

Hi, i did in my 2D game an item that when touched causes the player to get points for helath, but idk why doesnt work

what i did wrong?

public class lifepoints : MonoBehaviour
{
    [SerializeField] private float lifepoint = 10;
    [SerializeField] private ValeriaController valeria;

    private void OnTriggerEnter2D(Collider2D other)
    {
        if (other.CompareTag("Player"))
        {
            valeria.TakeHealth(lifepoint);
            Destroy(gameObject);
        }
        
    }
}```

[wintry quarry]

Start debugging your code with Debug.Log

[acoustic belfry]

yep, doesnt show up

[wintry quarry]

what doesn't

where did you put the log

[acoustic belfry]

inside the other compare tag

[wintry quarry]

put it outside

and print the tag too

obviously we're not getting INSIDE the if

[acoustic belfry]

ok

[wintry quarry]

or the object would be geting destroyed

    private void OnTriggerEnter2D(Collider2D other)
    {
        Debug.Log($"Entered a trigger {other.name} with tag {other.tag}");
        if (other.CompareTag("Player"))
        {
            valeria.TakeHealth(lifepoint);
            Destroy(gameObject);
        }        
    }```

[acoustic belfry]

neither works

[wintry quarry]

then you haven't set up the conditions in the scene correctly for OnTriggerEnter2D to run

[acoustic belfry]

oh

[wintry quarry]

Show the inspectors of the two objects you are expecting to interact

[wintry quarry]

neither of these colliders is a trigger

[acoustic belfry]

huh

[wintry quarry]

OnTriggerEnter2D requires that at least one of the colliders is a trigger

otherwise it's just a regular collision

[acoustic belfry]

you mean the IsATrigger check?
for a weird reason when i enable it on the item...it dissapears

[wintry quarry]

The "Is Trigger" checkbox on the collider, yes.

wdym by "it disappears"?

Maybe you mean it's falling through the floor or something? Because that makes sense

if it has a Rigidbody and no physical collider and gravity is enabled on it, it will fall through the floor

[acoustic belfry]

ooh, that makes sense, idk is too far from the initial camera, when i get there its just gone

[wintry quarry]

it's not "just gone"

don't forget you have the scene view

and the hierarchy

you can look at the state of any object in the scene at any time

[acoustic belfry]

yep, it falls to it demis

[wintry quarry]

mystery solved

[acoustic belfry]

but how do i fix that?

or i better use overlapping?

[wintry quarry]

It depends what kind of behavior you want

is there a good reason this object actually even needs a Rigidbody?

Does it need to physically interact with the world in any way other than being triggered by the player touching it?

[acoustic belfry]

gravity, it acts like blood

the idea is that when i kill an enemy this one explodes in shards and in this item, wich falls to the ground, and the player can touch it for get more health. Is for make an fast acting gameplay needing to kill enemies for heal like in UltraKill

[wintry quarry]

So if you want it to physically interact with the world but not the player you need two different colliders

one for interacting with the world and one for being a trigger for the player

[acoustic belfry]

oooh, ok, thanks

[acoustic belfry]

i dont know what went wrong, but still doesnt detects it, why?

[wintry quarry]

you'd have to show what you did

[acoustic belfry]

i added a second boxcollider, this one with IsTrigger in on

[acoustic belfry]

so what i did wrong?

[wintry quarry]

well the two colliders would need to be on separate child objects first of all

with different layers

and oyu'd use layer based collisions to set up the interactions

[rugged beacon]

may i ask when you guys learning the save load system, which guides used to follow ?

[acoustic belfry]

ooh, got it

[rugged beacon]

i think you can use this to avoid using another gameobject

[hidden fossil]

does anyone know why its doing this when a wave starts?

its like this before the game starts

[slender nymph]

You're using ToString on a list instead of it's count or some other numerical object

[hidden fossil]

would this be the wrong way to use a text function? [SerializeField] private TMP_Text WaveTxt;

[solemn crypt]

Working on main menu script any help with it ?

I’m trying to just load levels

[slender nymph]

That part is not the issue, it's where you set the text that is

[keen owl]

why don't you just concatenate the waves inside quotes?

[slender nymph]

Yes, like I said you're calling ToString on the list object instead of on something that is a number (which is what I assume you want)

[hidden fossil]

ah fixed it

[acoustic belfry]

what's the difference between using OnTrigger and Physics2D.OverlapBox in efficency?

[slender nymph]

profile them and find out

[cosmic dagger]

You'd have to test out both options and check the difference in performance. There's no way to tell unless someone has specifically done it themselves . . .

[acoustic belfry]

i mean cuz i could more easily make my items using the overlap box, but all the people i see use the OnTriggerCollision

[teal viper]

It depends on your setup and use case.
If they have colliders anyway, then using physics queries would just add extra processing time.

[acoustic belfry]

i mean cuz they also have rigid bodies and using the OnTrigger causes some inconveniences

[teal viper]

Can't say anything as I don't know the whole context and/or what these inconveniences are.

[acoustic belfry]

well, the thing is, i want my enemy to explode in shards and items, and those items obviously for work need gravity wich is the rigidbody, but the issue is that when the collider is set to IsTrigger...it falls across the floor...i tried to use a child with another collision but it doesnt work as intended

[teal viper]

Why not use colliders and on collision enter then?

[acoustic belfry]

wat

oh

[teal viper]

You want them to collider with stuff, no?

[acoustic belfry]

yep

[teal viper]

Why a trigger then?

[acoustic belfry]

i always wondered how the enter worked

thanks

[teal viper]

Same as on trigger enter. It's called when the object is colliding.

[acoustic belfry]

oooh, makes sense, thanks :3

[cosmic dagger]

You can use whatever works for you. Most people will use trigger or collision methods because those are the first ones we all learn and they are simple, though, they may not work as well depending on your use case, like the speed of objects, multiple collisions at once, etc . . .

[acoustic belfry]

ooh, well, thanks, i will have that in mind :3
so they use it cuz is like the basic thing to do, but not always the perfect one

[frigid sequoia]

Can I not get how many scenes I currently listed on the build with the SceneManager?

Is that SceneCount?

Cause that kinda reads that is returning the number of scenes loaded??

That description makes me think it's gonna count stuff like if I have the same scene loaded twice.... https://docs.unity3d.com/6000.0/Documentation/ScriptReference/SceneManagement.SceneManager-sceneCount.html

[frigid sequoia]

So... loadedSceneCount returns only the number of currently loaded scenes. sceneCount counts all the scene that are loaded, loading or being removed, and sceneCountInBuildSettings returns just the length of the list on the build settings right?

[sour fulcrum]

i believe this is true yeah

[frigid sequoia]

Ok, cool, thxs

[acoustic belfry]

how laggy are overlapping?

[slender nymph]

"laggy" is not a descriptive term to describe much. If you want to know the performance impact of things you implement then use the profiler.

[acoustic belfry]

ok

well thanks

[modern solar]

hey guys super dumb question i think im missing a unity package that will allow me to use Awaitable namespaces but i cant find this damn thing
CS0246 The type or namespace name 'Awaitable<>' could not be found (are you missing a using directive or an assembly reference?)
anyone have any ideas, ive tried defining it myself which then causes a slew of other issues

[sharp bloom]

How do I register whenever a raycast stops hitting a collider?

Doesn't OnCollisionExit() work?

Collider is non-trigger mesh collider

[keen dew]

The question doesn't quite make sense, raycasting is a single event

If you have something like raycasting every frame and you want to know the first frame when the raycast doesn't hit anything anymore you'll have to use a separate variable to track that

[eager spindle]

whats the approach here, are you raycasting every frame until the raycast no longer hits anything?

[eager spindle]

I tried this in my own instance and it works, the only namespace I'm using is UnityEngine

I'm not sure if the name Awaitable conflicts with anything else. Try using UnityEngine.Awaitable instead?

[north kiln]

where's the error?

[sharp bloom]

I select certain objects by raycasting every frame

[modern solar]

this is the first instance of awaitable

then its referenced down the line

[eager spindle]

Awaitable doesn't exist in the current context
Could you try to right click it and see the fixes associated with this?

maybe one of the namespaces you're using conflicts with this

[north kiln]

well, Awaitable<bool>.MainThreadAsync isn't a thing for one

[modern solar]

oh i added that to try to fix it

it didnt work lol

[sharp bloom]

What I want is have a state on the object like isBeingRaycasted

[keen dew]

You'll have to make that yourself. Each raycast is a separate thing, they don't have any knowledge of previous raycasts

[sour fulcrum]

(and the things your hitting don't know anything about the raycast)

[north kiln]

is this in a completely different project or something?

Like, a different version than you're testing in where it does work

[modern solar]

no its libretro im trying to import it and this one reference is not working. @eager spindle there was a fix to creat a reference in another file and it just now sent out a new slew o errors

[modern solar]

so far it just doesnt work?

[north kiln]

Are there errors in Unity?

[modern solar]

yes just this one

[sharp bloom]

I know, but how should that be done? Yes I can make something like
if (hit) { object.isBeingHit = true } but that's in the update function and the object is changing constantly

I need to somehow cache it I think

[modern solar]

and now these

[sour fulcrum]

you cannot cache it, because as you said it's changing constantly

[north kiln]

Well, as the Awaitable being missing error isn't there, I'd say it's an artefact of the IDE and not a real error

what's the actual error that does exist point to?

[modern solar]

this here

[keen dew]

You'll have to explain what the end goal is to get suggestions because that by itself would be enough for what you're asking for now

[inner path]

what's your editor version?

[modern solar]

2022.3.49

[sour fulcrum]

but in general, yes in a lot of circumstances raycasting in update loops like that is a totally valid way to do stuff

[north kiln]

Awaitable support is 2023.1+ (i.e. Unity 6), support before then is spotty,

[sour fulcrum]

raycasts are fairly cheap and built to be thrown out constantly

[modern solar]

ffff

im wanting to bring it into vrc and i know if i do it in a newer version thats not compatible

[sharp bloom]

The thing is I need to also clear the isBeingHit flag somehow

[modern solar]

so is it just cooked then

[sour fulcrum]

clear?

oh

[sharp bloom]

Like set it to false I mean

[sour fulcrum]

show more code

where hit is declared and all that

[north kiln]

well, I'm surprised it even exists in that version. Though it might just be Awaitable<T> that doesn't

[modern solar]

i think its just awaitable

im thinking im going to have to rewrite all the code and replace it with Task

[inner path]

coroutine cannot fix the problem?

[modern solar]

whats that .-.

someone mentioned that yesterday when i was chatting about it

no clue what it is tho

i shall look into it

[inner path]

before awaitable cum up, coroutine is a common solution when you need to wait something do as an async function

[keen dew]

You can put isBeingHit = false to LateUpdate

[sour fulcrum]

this is correct but wherever your doing the raycast you can just use that result directly

[sharp bloom]

I think they start "fighting" rapidly back and forth

[sour fulcrum]

(was waiting on the code to show example)

[sharp bloom]

Or that was with update actually, I never tried lateupdate

[sour fulcrum]

eg. isBeingHit = Physics.Raycast(etc.)

[modern solar]

excuse me while i re write everything and die XD

thank you guys!

[sharp bloom]

public GameObject CheckTileHitting()
{
    RaycastHit hit;
    
    Physics.Raycast(new Vector3(projectedPos.x, projectedPos.y+1, projectedPos.z), new Vector3(0, projectedPos.y-1, 0).normalized, out hit); //fire ray directly above tilemap
  
    if (hit.collider != null && hit.collider.CompareTag("Tile")) //check if ray hits a tile
    {
        return hit.collider.gameObject;
    }
    else
    {
        return selectedTile;
    }
}

and

    void Update()
    {
        mousePos = Mouse.current.position.ReadValue(); //read mouse position
        worldPos = cam.ScreenToWorldPoint(new Vector3(mousePos.x, mousePos.y, 7.88f)); //convert mouse position into world position
        projectedPos = Vector3.ProjectOnPlane(worldPos, new Vector3(0, 1, 0)); //account for camera rotation
       
        if (tm.toolBeingUsed)
        {   
            selectedTile = CheckTileHitting();
        }
        
        if (selectedTile != null)
        {
            tm.selectedTile = selectedTile.GetComponent<gameTile>(); //send selected tile to tilemanager instnace
            selectedTile.GetComponent<gameTile>().StartHover();
        }
       
    }

Basically I need "StopHover()" somewhere

[north kiln]

Physics.Raycast returns a boolean, you should be using it instead of checking whether the hit's collider is null

[acoustic belfry]

but i mean, if the script is in the IsTrigger on Children, how it will delete all the object and not just itself?

[keen dew]

var newSelectedTile = CheckTileHitting();
if(selectedTile != null && newSelectedTile != selectedTile) {
    // call StopHover here
}
selectedTile = newSelectedTile;

    if (CheckTileHitting(out GameObject selection) && selection != selectedTile)
        selectedTile = selection;
        OnSelectionChange();
}

[keen owl]

Well I don’t think you can get gravity without a rigidbody without very complex coding. Why don’t you want rigidbody on your character may I ask?

[willow shoal]

because my player reflection from the wall

when i use rigidbody

[keen owl]

What do you mean reflection?

[willow shoal]

when he jumps on the block next to him he bounces off it

[keen owl]

Did that object or your character have a physics material with a bounce value greater than 0 at all?

[willow shoal]

not sure

i think yes

where is this option

in rigidbody

or its a code

[keen owl]

Should be in the component, a physics material field

Your collider has one as well

[sharp bloom]

Ye this works for me thanks

[eternal needle]

Its not very complex code, it's literally the same code as moving an object horizontally

[eternal needle]

If you want an object which doesnt use physics, like doesnt bounce or push other objects, its probably better to make your own character controller. Youd basically do gravity the same way you showed when you used unitys CC

[keen owl]

Wouldn’t you have to calculate a collider below you and fall towards it exponentially (while calculating all other physics factors such as mass and terminal velocity)? Or am I overthinking it

[eternal needle]

This doesnt really make sense at all "calculate a collider below you and fall towards it".
You can use physics cast to see if anything is in the way, but that's not specific to gravity. You wouldnt want to move through objects horizontally either

You pretty much just add -9.8 * time.deltaTime or fixed delta time to a float and that's your current vertical speed.

[keen owl]

Ah yes casting, didn’t think of that. Still seems harder than using a standard rigidbody which is why I questioned it earlier

[eternal needle]

A rigidbody at first will be easier to setup, but if you need specific setups where you fight the physics system, it becomes more of a pain then just learning how to use a capsule cast

[keen owl]

I spent a while trying to create somewhat realistic physics simulations for gravity and mass with scripting and it definitely wasn’t fun at all to say the least lol.

[eternal needle]

Well unitys physics system isnt realistic to our world in the first place. Mass doesnt affect the gravity, theres no air resistance (or other stuff u mentioned like terminal velocity) coded in

I mean truthfully if you were just coding gravity I dont consider that complex, but other stuff like terminal velocity or air resistance I could see being very tricky. Youd have to have a good understanding of physics already, plus it likely wouldnt be cheap to calculate any of that

[keen owl]

I don’t see why air resistance would be useful unless your game has parachutes which could be simulated with lowering gravity a little or counteracting the force but that seems more expensive than it needs to be to be honest

[eternal needle]

Well thatd fall under "realistic physics simulations for gravity"

[supple wasp]

Can you try to rephrase what you mean? What is all the ones and what is a recorded frame? I get you have a keyframe dictionary and trying to add keyframes with the transform overrides. But where are you having issues?

When I put a frame already recorded of the object that was manipulated, that position remains in all the frames that are there.

instead of being different

where do you "put a frame already recorded" in code?

[burnt vapor]

This server, and especially this channel, is purely for questions. Please try sticking to it.
Good job though!

[broken dagger]

What is null in unity and how do we use it, and is there any documentation about it?

[wintry quarry]

null is not a Unity concept. It's a C# concept (and also many, many other programming languages) and it's the value of a reference variable that isn't referring to any actual object.

You can imagine your reference variables are like pieces of paper with the address of a house written on them. If the variable is null, it means there is nothing written on the paper.

[broken dagger]

Oh ok, ty, now I understand what null is, it’s the abstance of any value of a reference type. Thanks

[burnt vapor]

null exists in Unity. If you want to visualize this you can enable nullabillity by placing your code in between #nullable enable and #nullable disable blocks. Unity will then explicitly specify indicate what values can be null in the code, though note that this could be a false-positive and you could choose to ignore it.

Once CoreCLR comes around the support is probably/definitely improved by introducing attributes and configuration around this.

[grand snow]

🤔 someone asking what null is wont understand what the core clr is

[burnt vapor]

Good thing they do know how to ask questions so if it confuses them they can always ask for more context

Which, by the way, is also the reason why I don't go into detail. It's entirely separate from the actual answer and not really important

[raw fiber]

guys what is the problem i got my phone plugged in and everything worked last time

[grand snow]

If you run adb devices does it show up?
If not make sure usb debugging is enabled then re plug it in and confirm if it asks for permission

[raw fiber]

what is abd devices

[grand snow]

A command to run in cmd or powershell. It shows the connected android devices adb can find

[raw fiber]

ah ok thank you

[grand snow]

Adb is used to install the app (android debug bridge)

[raw fiber]

how to enter it in cmd it only gives me a massage that its not found

[grand snow]

You will have to find the adb provided with your unity install. Otherwise it can be installed via android studio

[raw fiber]

i just want to download the apk file of my game

[grand snow]

Then unplug your phone, make sure usb debugging is on and plug in again and accept a msg on your phone

It may ask if you should allow a pc to connect blah blah

[raw fiber]

where to enable usb debugging

[grand snow]

https://developer.android.com/studio/debug/dev-options#enable

Follow this to make the hidden menu show

[rocky canyon]

or go into settings and manually turn on usb debugging

[raw fiber]

what setting unity or my phone

[rocky canyon]

tap, tap, tap, tap, tap, tap. "You are now a developer"

[grand snow]

Yea we got to that part 🙃

[raw fiber]

i already downloaded my apk once but everything was the same then now

[grand snow]

Your phone. Check the android dev page above

[raw fiber]

i just want to download thhe file

nothing on my phone or something

only a fcking file

[grand snow]

Okay easy mode is plug in phone, copy onto phone storage, install on phone.

[raw fiber]

last time i got the file on my pc and i want the same thing to happen again

[grand snow]

Most phones show up in explorer so you can copy files onto it

Unity made an apk when you built it

Go check where you told it to save to

[raw fiber]

wwhere to see?

[grand snow]

When you press build it should ask you to pick... Go check yourself

[raw fiber]

it worked

thanks everyone#

[acoustic belfry]

Hi, i tried to make an item that needs to collide with tileset but also be obtained by the player, i added an OnCollisionEnter for when the player touches it, but if the player life's >= 100 it should not get used, the problem is that due being a rigidbody, it bumps with the player, and if i exclude it layer from the item's rigidbody, it obviously doesn't trigger.

So how i can make for that when the Player touches it when health is full it just surpass it and doesnt bump it?

[astral falcon]

Just like you wrote it. Check for the player health and if its full, do not execute the rest of your stuff

You might have to separate the visual object from your collider to be able to check before visually updating it

[delicate portal]

How to subscribe to EventHandlers using lambdaM

[acoustic belfry]

no but i mean, i know how to check it life, the issue is that if i dont execute nothing they will just hit each other

[grand snow]

On collision enter, get player component from hit object. Check health. Either do thing or do not.

Oh wait you want the collision itself to not happen? Or just skip some logic?
You may have to disable the colliders or change layers to avoid collision

[acoustic belfry]

Yes, i want the collision to dont happen. I know how to check if it health is not 100, thats how i discovered this issue

[grand snow]

You can also add specific exceptions for colliders: https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Physics.IgnoreCollision.html

But if you have many objects then I would avoid doing this

[eternal needle]

Did you look at the docs? It's the same for subscribing to any delegate, you just need to know what the parameters are

[delicate portal]

No parameters, yes I did

[acoustic belfry]

Ok, but how, if the way to activate the logic is that they collide
:<
my idea was to do this for make an Item that has gravity and can get accesed

[eternal needle]

There are no parameters? Sounds weird for anything EventHandler. But in that case it's just
eventName += () => { your code}
https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/lambda-expressions
And wow that's a pain to type on mobile lol

[grand snow]

er you arent making sense anymore. You cant have a collision and also not? Are you thinking about triggers?

[delicate portal]

Yeah no sorry I mean no custom parameters.

[eternal needle]

Im not really sure what you mean by custom parameter. Either way you just need to look at what variable types the delegate (event handler) uses and copy those the input parameters part of the lambda expression

[acoustic belfry]

its a long story, and i know this is not making sense thats why im feeling frustated

i originally wanted to use triggers, but by doing so, it just fell down the ground, so i thought of using CollisionEnter, but i didnt realized they will bump each other when the item is not necessary

[grand snow]

what fell sorry?

[acoustic belfry]

the item

[grand snow]

a trigger/normal collider can be fixed and not fall if you configure the rigidbody correctly

[astral falcon]

as said, you need to detach it then. You gotta get the collision, check and then do the animation. You can easily just check for playerhealth while your object is kinematic, and if it should interact, turn it non kinematic and add some force or whatever. you can play around with that

[polar acorn]

Colliders are solid objects. If two colliders will interact at all, they cannot ever occupy the same space (well, at least not for long before one of them gets flung out into space)

Triggers define an area that can detect things that are in them. They don't have any "presence", they merely describe empty space.

For example, you might be "In the living room" but you're not actually touching the living room. That's just the definition of the space inside those walls. The "living room" trigger likely contains a "couch" collider, which you can't ever be intersecting with, you would be colliding with it.

If you want something to have a physical presence that keeps things out, use a Collider. If you want something to be intangible but define a space that can be entered, use a trigger.

[grand snow]

what are you doing that has EventHandlers still 😐
Modern stuff is usually just public event Action foobar;

[delicate portal]

I'm using Actions my brain was just fryed

[acoustic belfry]

what if i want both

i mean, i heard of the idea of using childs wich made a lot of sense, my issue with that system is, who will have the script? the main, or the child?

[grand snow]

cool cool

[polar acorn]

Then use both

[grand snow]

the monobehaviour has to be on the same gameobject to get the event messages. so you may need another comp to "get" it from a child

i wish unity added real events for this shit

[polar acorn]

Collider that defines the solid part, child object with a trigger that has the detection radius

[grand snow]

yea thats a sane idea. you could technically have 2 colliders on 1 game object to simplify events...

[acoustic belfry]

my issue is, the child will get then the script? Ok, but how do i make it delete the whole object and not just itself?

[polar acorn]

It needs to be on the same object that the rigidbody is on to get event messages. Rigidbodies contain all child objects that don't belong to other rigidbodies

[grand snow]

Ohh yes you are right mb

[polar acorn]

When a Rigidbody interacts with a collider, what happens is the Rigidbody calls all of the event messages on itself, then it calls it on the object the other collider is on. If both objects have a Rigidbody, they'll both do the first thing and call the functions on themselves, and then when it comes to the "others", the message has already been handled and they won't call again

So, you can put the script on either the trigger child, or the object with the rigidbody, and it should work

As long as the other object has a rigidbody to call the function. If not, then it must be on the parent object with the rigidbody

[acoustic belfry]

oooh, so if i put the script in the main, it will activate ALL the collisions it has

[acoustic belfry]

or i got lost?

If the script is on an object that also has a Rigidbody, it will call the rigidbody event methods on all collider objects contained by that rigidbody, as well as the other object it hits and only that object. If both objects have a Rigidbody, they will each call the event functions on all collider objects contained by that specific rigidbody

So, basically, Child Collider gets hit. Tells its rigidbody "Hey, I got hit". Rigidbody tells all other scripts on this object "Hey we just got hit", and then it tells the thing that hit them "Hey, you got hit too."

If that object also has a rigidbody, it'll go tell its rigidbody and kick off the same process again

[acoustic belfry]

Oooh, so in theory if i make a child with a Trigger Collider it will work as the trigger collider of the main object, despite it has another one

Btw whats the difference between doing this and doing Physics2D.OverlapBox?

[polar acorn]

An OverlapBox wouldn't need any rigidbodies involved to detect the colliders

But, it does still need colliders

If you already have the rigidbody, it's cheaper to use the rigidbody events than overlaps (half the work is gonna be done regardless, might as well use it)

[acoustic belfry]

i dont need the rigidbodies for detect, i need them for dont phase the floor, or thats what you mean with detect?

[polar acorn]

Rigidbodies provide an object with the ability to use the physics system.

If you're not doing physics, you don't need them. If you are doing physics, you do need them

[acoustic belfry]

i need them

[polar acorn]

So then since the object already has a rigidbody, might as well use rigidbody event functions

[acoustic belfry]

i mean, all my enemies use overlapboxes for attack, the thing is, i want their rigibodides to only affect the floor, but i want the player to be able to phase thought them, idk i feel it feels better

or this is a bad idea?

[acoustic belfry]

hey it works, thanks :3

but now i have a existencial crissing trying to figure out if i should keep the overlap boxes of my enemies or replace them with mini-colliders like i did with the item. They both in theory have the same function, but i heard overlap is laggier or idunno

[polar acorn]

If it becomes a problem, fix it then

We're talking like, a few cpu cycles

[acoustic belfry]

o h

dang, i want my game to have a lot of things on it and still have nice performance

well, thanks :3, this helped me a lot

[slender nymph]

i heard overlap is laggier
don't make assumptions. you've been told several times if you have actual performance concerns then use the profiler.

[spiral carbon]

so i watched https://youtu.be/Weu305NLMqo?si=npmH7FQhX8sjPWSS and the first script isnt working pls may some one help

[acoustic belfry]

oh right, well i will investigate it now, thanks :3

[slender nymph]

[spiral carbon]

so he has like this little tab underneath the script to put the spine or sum but i copied it and i didnt get the little tab

sorry for not the best explonation this is my first game

[polar acorn]

Screenshot what you're seeing, and what it should look like

[spiral carbon]

so thats his

[slender nymph]

fix your compile errors

[spiral carbon]

thats mine

[polar acorn]

Do you have any errors in the console

[spiral carbon]

only this

[slender nymph]

screenshot the entire console window

[spiral carbon]

there is the entire screen

[slender nymph]

then you've copied something wrong

or you just didn't bother to save

[polar acorn]

Okay, can you show your !code, as it is in your file?

they are the 3

[slender nymph]

please pay attention to the instructions you've been given instead of ignoring them

[polar acorn]

Correct. Your code is very wrong. Follow the instructions for configuring your IDE and write it correctly with the help of tools that can actually function

[spiral carbon]

Im so confused

[slender nymph]

follow these instructions: #💻┃code-beginner message

[spiral carbon]

my brain hurts now

[polar acorn]

You click the link. Then you follow the instructions.

[spiral carbon]

im too stupid for this

[spiral carbon]

i am but im dyslexic

[eternal needle]

you should really start with beginner concepts and learn c# properly. you aren't gonna succeed with your first attempt being a multiplayer ragdoll. this is extremely complex

[spiral carbon]

im not making it multiplayer but its the only tut i could find

[eternal needle]

my statement still stands. active ragdolls are not at all easy to setup, and you dont know basic c#. Follow the command they linked you above to configure your ide for unity, but i also suggest going through the pins and the intro to c# stuff. It will really help if you actually know what you're writing

[spiral carbon]

oh

[acoustic belfry]

sorry for bother, but i have almost the same problem

i have the parent with the rigidbody collision and boxcollider and child with the boxcollider for interact with player, it all works great. The issue is that the parent rigidbody keeps bumping with the player, and if i exclude the layer, the child doesn't work. I tried to use the Layer Matrix...but for an strange reason...it didnt worked...

[slender nymph]

you can exclude the layer on the specific collider or put the child object on a different layer if using the layer matrix

[acoustic belfry]

already done...

[slender nymph]

show it

[acoustic belfry]

holup, the layer matrix how it was? I thought you said changing it in the inspector...wait a sec, i will test it

nvm i tested it

for a weird reason the layer matrix doesn't work, i mean, it still collisions despite i change it

[slender nymph]

now show how the objects are set up

[acoustic belfry]

and if i exclude the layer from the collision, it will cause the logic to dont shoot

[acoustic belfry]

holup

[slender nymph]

so exclude the other one?

[acoustic belfry]

huh

[slender nymph]

congrats, you have modified the wrong layer matrix. you modified the one for 3d

[acoustic belfry]

o-o

._.

oh

[slender nymph]

did you not notice there were Physics2D settings directly below the setting category you have selected?

[acoustic belfry]

no...

well now it works, thanks

[covert bridge]

Hey does anyone have any good 3D blackjack tutorials? I’m having a really hard time since I only find 2D ones from a few years back

[eternal needle]

itll be very unlikely you find good tutorials that are extremely niche like this. emphasis on good.
look for tutorials on what you actually get stuck on.

[slender nymph]

also how would 3d blackjack be any different than 2d other than visuals?

[rocky canyon]

learn to adapt.

[timber tide]

change canvas raycaster to physics raycaster, done

[outer gorge]

ok I'm new to this server but I'm having issues with IFactorySettings

error CS0426: The type name 'IFactoryControls' does not exist in the type 'DefaultControls'`

I'm using Unity version 2019.4.17f1

[keen dew]

What is IFactorySettings and why are you using a six year old version of Unity?

Discussing modding isn't allowed in this server

[outer gorge]

oh crap

well

I'll be on my way

[long jacinth]

howdy so i have this gun and i wanna knockback the player when i shoot the problem is that i cant get it to always make the player to knockback in the exact oppisite direction he is facing this is the code i use Player.GetComponent<Rigidbody2D>().AddForce(GunText.transform.position * -RecoilForce, ForceMode2D.Impulse); Destroy(bulletInstance, 3);

[slender nymph]

it's transform.position is not the direction it is looking, you want it's transform.right or transform.up depending on what direction it points when not rotated

[wintry quarry]

Alternatively use AddRelativeForce with Vector2.right or Vector2.up

or I guess down or left if you want the opposite

[long jacinth]

problem is that the gun faces the mouse

[wintry quarry]

then your quesiton was inaccurate. You said "make the player to knockback in the exact oppisite direction he is facing"

You should have said "knockback opposite the direction to the mouse"

[long jacinth]

oh sry

[wintry quarry]

presumably you're already calculating that direction to shoot the bullet

so just use the opposite of that direction

[slender nymph]

and if the gun is still rotated to face the mouse then you're still just going to use its transform.right or transform.up

[long jacinth]

the force is stronger in some directions :/

[wintry quarry]

you're probably not normalizing the vector then

[long jacinth]

direction.normalized i did

[wintry quarry]

show the actual code

full code

[long jacinth]

Debug.Log(direction);
        if(!Player.GetComponent<PlayersMovement>().IsGrounded())
        {
            Player.GetComponent<Rigidbody2D>().AddRelativeForce(direction.normalized * -RecoilForce);
        }```

[verbal dome]

Relative force 🤔
Show full code

[wintry quarry]

where did direction come from? It's probably a world space direction and thus not suited for use with AddRelativeForce

[long jacinth]

    {   
        Vector2 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
        Vector2 direction = mousePos - (Vector2)Gun.transform.position;
        GameObject bulletInstance = Instantiate(BulletPrefab, FirePoint.position, FirePoint.rotation);
 
        bulletInstance.GetComponent<Rigidbody2D>().AddForce(FirePoint.right * BulletForce * -1f);
        bulletInstance.GetComponent<BulletCol>().bulletDamage = BulletDamageDeal;
        
        Debug.Log(direction);
        if(!Player.GetComponent<PlayersMovement>().IsGrounded())
        {
            Player.GetComponent<Rigidbody2D>().AddRelativeForce(direction.normalized * -RecoilForce);
        }
        
        Destroy(bulletInstance, 3);
    }```

[wintry quarry]

Also you most ikely want ForceMode2D.Impulse here

[wintry quarry]

yeah this should be regular AddForce and it should be an impulse

[long jacinth]

it just cancels sideways knockbacks

[fleet venture]

can you not use records in unity?

[rich adder]

C#9 it should no?

[rich adder]

Check this. https://docs.unity3d.com/Manual/csharp-compiler.html

9 init and record support comes with a few caveats.

The type System.Runtime.CompilerServices.IsExternalInit is required for full record support as it uses init only setters, but is only available in .NET 5 and later (which Unity doesn’t support). Users can work around this issue by declaring the System.Runtime.CompilerServices.IsExternalInit type in their own projects.
You shouldn’t use C# records in serialized types because Unity’s serialization system doesn’t support C# records. "

[fleet venture]

oh

why does unity have such a limited version of c#

[rich adder]

Because right now it's using .NET 4.x

Soon they will convert to Core clr, which gets the latest .net

[teal viper]

Because it's using Mono, an open source dot net backend, and it was not updated in a while. It's gonna switch to Microsoft dotnet afaik.

[fleet venture]

ah

nice

that is nice

[crystal bridge]

Any recommendations on how I should go about Debugging between 3 scripts? I'm also concerned that I may have did something wrong with the components since that has happened before.

[teal viper]

Same as debugging one script. What exactly is the problem?

[crystal bridge]

Since the problem is unknown, it is unclear which of the scripts is having the issue. Of course it could be more than 1, but again, we don't know. Plus, debugging statements can't really help if it's a component setting issue.

[wintry quarry]

Plus, debugging statements can't really help if it's a component setting issue.
Of course it can...

As always you start with the code nearest the issue and work backwards as needed

[teal viper]

As praetor said, you start with identifying the issue and looking at the code directly related to it.
If you need more help, you should share the details of the issue.

[crystal bridge]

@teal viper Details are here

[teal viper]

What is the actual issue? I don't see the "I expect X to happen, but Y happens/ X doesn't happen". The actual direct issue is not conveyed.

[honest violet]

i am kinda losing it

tryna help a friend make something in vr and im trying to make a script to change the turn type, but i keep getting these erroors.

[slender nymph]

it's a little further down before they admit that it's all AI generated

[slender nymph]

do those types exist in the project somewhere?

[crystal bridge]

Mentioned in the next comment.

When I click on the Photo object, the dialogue box/words/portrait aren't appearing at all. It is currently set to inactive in the hierarchy (seen in pics above), but I intended for it to appear with the customized features from the fields.

[teal viper]

So, if the objects you want to appear are inactive, they obviously need to be set to active. Are you doing that? And where?

[crystal bridge]

While I did try them active, they are currently inactive because the script was to make them active and appear

[slender nymph]

okay so did you add the correct using directive(s) in the code?

[teal viper]

Does the~~ script~~code that makes them active actually run? Can you pause your game when this is supposed to happen and inspect your hierarchy?
