I think whatever version of Unity you're using doesn't support switch expressions

#

but the code for this asset is using it

ivory bobcat
#

Fix your IDE

minor vault
wintry quarry
#

Unity 2019 doesn't support C# switch expressions

#

it's too old

#

Your options are:

  • upgrade Unity
  • rewrite that code
  • don't use that asset
minor vault
wintry quarry
#

note you really shouldn't go around sharing code for paid assets

oblique gale
#

will there be a change if I used Visual Studio Code instead of Visual Studio in terms of speed? because my pc is barely holding on with Unity alone...

Hello. why am i getting this error.

fringe plover
#

i started working with Networking rn, and i dont know, do i need to use NetworkRigidbody instead of normal one?
ok ill use it cuz some components are asking for it

wintry quarry
#

I think you meant StoveCounter.State not stoveCounter.State.

#

StoveCounter is the class
stoveCounter is a reference to an instance of the class

patent compass
#

u are right. lmao, thanks

The numbers get turned around, (42 becomes 24) is there a way to fix it

Log the value of integer to display

nimble apex
#

somehow i encountered a strange thing

bright zodiac
#

such as?

nimble apex
#

theres a card object in my game scene , this card object will have its material loaded when we enter the scene, it has no valid material until then

#

i have a script, that will modify a parameter of the material

#

however, it seems that even it successfully modified the param, the card cannot reflect the changes

#

i need to get into the inspector and manually modify the value in order to get it works

wintry quarry
north kiln
#

Are you modifying emission by any chance

wintry quarry
#

You know that Renderer.material creates an in memory copy of the material. It won't modify the original.

nimble apex
#

i know, but it will modify that object with the renderer mat right

ivory bobcat
#

Show some code

nimble apex
#

ok

#

sry i cant use discord on my working mac, so i will do screenshot

rn_image_picker_lib_temp_70b884e8-5bc9-4f8e-b23a-49db6c020b81.jpg
wintry quarry
#

Yep you made a copy of the material

#

With Renderer.material

nimble apex
#

yes

north kiln
#

You reassign the shader??

nimble apex
#

and the code successfully changed the parameter of that material

north kiln
#

That's not a check, that's an assignment

nimble apex
#

right

#

the card shader was replaced

north kiln
#

Implicit bool conversion strikes again

#

Also doesn't onenable occur before start

wintry quarry
#

Right so that will always be false yes?

rare basin
# 
    public GenericDictionary<int, UnityEvent> diamondHPThresholdIncome;
    private HashSet<int> triggeredThresholds = new HashSet<int>();

    public void CheckForDiamondIncome()
    {
        var currentHealthPercentage = enemyUnit.healthSystem.LifePercentage();

        foreach (var threshold in diamondHPThresholdIncome.Keys)
        {
            if (currentHealthPercentage <= threshold && !triggeredThresholds.Contains(threshold))
            {
                diamondHPThresholdIncome[threshold]?.Invoke();
                triggeredThresholds.Add(threshold);
            }
        }
    }

What's the difference here if I'd use private List<int> triggeredThresholds instead of HashSet<int>? None?

nimble apex
north kiln
#

I don't even know what happens if you assign a null shader

wintry quarry
bright zodiac
#

instantiate a new one via Material mat = new Material(Shader.Find("someShaderType"));
then just copy the properties via mat.CopyPropertiesFromMaterial(oldMat)

nimble apex
wintry quarry
nimble apex
#

we change the shader

rare basin
#

so If i just want to check if a collection contains element X (not plan to do anything with that element, just check if it's there) it is better (faster) to use HasSet?

rare basin
nimble apex
#
  1. this script should be executed after 4
wintry quarry
north kiln
nimble apex
#

yeah i just found out its not replacing material , but the shader instead

bright zodiac
nimble apex
#

damn wait

rare basin
nimble apex
#

bruuuh its fixed!!!!

bright zodiac
#

magical

#

😅

nimble apex
#

the weird thing is, even i put the urp ref on start, the parameter still changed

#

i swear i saw that

#

so i think , welp it should be fine? but then the changes didnt reflect

#

lol ty guys

north kiln
#

Check with the debugger next time and you'll see what executes when and can be extra sure what you saw

nimble apex
#

ok ty

Well, it's definitely not gonna work as it is now

#

I think we went over it earlier today or yesterday...

queen adder
#

mhm we did and that worked for smth else

teal viper
#

Well, it's the same issue...

queen adder
#

actually its not

#

if we use what we talked about earlier it will go directly away from the target which is what we needed

#

i swap the values and it just mirrors movements

#

now we just want it to go to the target

teal viper
#

First let's clarify one thing: when we say target, we mean the position/direction that we want to move to. Not any specific target in your game.

queen adder
#

yes

teal viper
#

Yes. And so the direction of movement is always target position - origin position.

#

And you move the object by adding direction times speed to it

queen adder
#

yes

teal viper
#

This is common sense and anything else would make things more complicated

#

And that's not what you have currently

Hey, is there a thread or website with some basic "do"/"dont do" tips for beginners ?

Another question to be sure, private vars are usually named with the _ prefix yes ?

teal viper
queen adder
#

yep

oblique gale
#

It did turn it back to 1 but for some reasons, when the saving happens, it returns back to 0 even tho it's already been set to 1

teal viper
#

Before/after

eternal needle
#

it doesnt matter what you think it was for, if thats the only place you assign a value to .day, then that is the place where it is assigned 0

#

im not sure where that 3rd debug comes from, because theres only 2 shown here. But its still clear that its initialize to 1 correctly

teal viper
#

Or it's not assigned at all and it's the default value.

eternal needle
#

assuming they didnt cut out a default ctor

oblique gale
teal viper
#

Sounds like your code is erroring and not executing as expected.🤷‍♂️

oblique gale
#

It shows an error for Line 46 rooting from Line 26

image.png image.png
teal viper
#

gamedata is probably null before you load.

#

Where is that debug that prints 0 located btw?

oblique gale
teal viper
#

A method that errored would return immediately, so that's not possible.

#

You should show us the stack traces of the messages.

eternal needle
oblique gale

#

then you should properly look at why the error happens through the stack trace, which you can see by clicking on the log. At the very bottom you should see more about it, like what even called the method that caused the error

somewhat silly question, I have a poco class like this

public class TypeData

    [HideInInspector] public string name;
    [HideInInspector] public string typeString;
    public List<string> assetList;

    public TypeData(string newTypeString)
    {
        typeString = newTypeString;
        assetList = new List<string>();
        name = newTypeString;
    }
}

and I have a list of them, How could I go about sorting that list based on their name?

#

usually i would just use Sort() but this doesn't implement that and It wouldn't know to reach for name

keen dew
#

but List does implement that, this one doesn't need to

Transform snowParticleClone = GameObject.Instantiate(snowmanParticle, transform.position, transform.rotation); Destroy(snowParticleClone.gameObject, 1f); why is this giving me Can't destroy Transform component of 'SnowmanEffect(Clone)'. If you want to destroy the game object, please call 'Destroy' on the game object instead. Destroying the transform component is not allowed.?? i literally use that same code for all of my particle and all of them works fine except for this one

Ah anyone here use Mirror for multiplayer? I'm facing a problem, the OnCollisionEnter method doesn't call on client but it work on host (to popup a canvas). Here my setup:

  1. Car (networkbehaivor, boxcolider, rigidbody networktransform, networkrigidbody).
  2. House (monobehavior, boxcolider)
  3. All client control 1 car, client has no authority, client call Command[bypass authority] method to tell host to move the car.
    Whether it's the host or the client who is moving the car, the house only popup the canvas on host.
ivory bobcat
#

Fix errors from top to bottom, if possible. Else you may be evaluating false positives

#

I'm assuming you're destroying a reference to a Transform component somewhere.

i instantiate and destroy that particle during 3 scenarios. the first one is if the object/snowman lifetime hit zero i instantiate the particle then destroys the snowman, for this scenario the script is not attached to the snowman that is being destroyed. the second one is if the snowman hit a bullet before a certain time. the third one is if the snowman hit a bullet after a certain time. for the second and third scenarios the script is attached to the snowman that is being destroyed

its referencing my unit selections code for the instance but i just don't understand why its erroring

hoary karma
#

i didnt realize i accidentally put that script in other object aswell

keen dew
#

best guess is that you didn't create the list

stark sonnet
gaunt ice
#

UnitSelections.Instance.unitList.Add(this.gameObject);
three possibilities, instance is null, unitList is null, or both of them indeed after you fix one

stark sonnet
#

thats my unit selections code that its supposed to be referencing

gaunt ice
#

where you set the _instance?

stark sonnet
#

yes that should be one of the first things set in the code.

#

Im sorry. This is all new to me. I didn't realize selecting multiple units would be so difficult 😫

keen dew
#

So does that mean you figured out what's wrong?

stark sonnet
#

I've looked it over again and again and I just cannot see what's wrong. I've even went back through the tutorial to see if I maybe typed in something wrong and I didn't see any errors.

keen dew
#

The Awake method in UnitSelections is only halfway finished. Look that up in the tutorial.

#

Oh! I see now. I'll change that and see if it works

#

That absolutely worked. I must have been typing too fast and forgot my else statement. Im a dumbass 😫 thank you for the help!

autumn tusk
#

ok so i know theres a better way to do this

#

so right now i have an enemy script, with my enemy script being divided into two parts

one controls the movement and manages health and collisions
the other controls the enemy's hands, which pivot towards the player

#

what i want to do is make it so that when the enemy dies, the hands stop moving and the enemy no longer flips to face the player

#

i set my health to public and my hand script to pull the health value, but it falls apart when i summon in multiple instances

#

once i kill all enemies, all hands on all enemies stop pivoting

ok i was thinking

if i use an if statement to check for the current tag that could work

hey
i got a OnCollisionEnter function in a parent gameobject, it has a Rigidbody and a script only
i got a child with a meshcollider

when the meshcollider detects a collision, OnCollisionEnter is called in parent

my question is: can i get the "source" of the call of OnCollisionEnter from the parent ? I would like to know what child is the source

edit: or even can i pass some extra data to the parent ?

rare basin
#

i meant the namespace

verbal dome
#

I think you gotta use the RuntimeAnimatorController type

rare basin

oh didin't know it exists

#

that fixes it then

Not sure, I have done that but dont remember how, can check in a moment probably

rare basin

How do you insert an element at runtime into the middle of a layout group? Say I have a vertical layout group, with buttons #1,3,4 already in it, and now the player just unlocked button #2 so I want to create it and add it to the UI. I only know the SetParent() way of adding to the group, which adds it to the bottom

Hey guys, Sometimes during my game, something wierd happen and I am not sure why. I have 2 code. One to keydown SPACE and other F1 but sometimes during the game when i use SPACE it does what is inside the F1 code.. and I cant understand why.. here are both: ```cs
if (Input.GetKeyDown(KeyCode.Space) && _canShield){

        if (!_hasShield && !_uiManager.isCooldown){

            StartCoroutine(ShieldOnTimer(3, _shieldCD));
            _uiManager.StartCooldown();
            
        } 
    } ```  and the other: ```cs

if (Input.GetKeyDown(KeyCode.F1) && _isF1 == false){
ToggleF1();
_f1.SetActive(true);
} else if (Input.GetKeyDown(KeyCode.F1) && _isF1 == true){
ToggleF1();
_f1.SetActive(false);
} ```

#

why in the world would the game do what is inside the F1 keycode if I use space?

safe root
verbal dome
#

Yeah, in other words not snappy

#

The solution I linked solves that while still using forces instead of directly changing rb.velocity

Got it thank you

how can i add an offset to this

wintry quarry
verbal dome
#

You can't "offset" a transform. You can offset a vector though with addition

wintry quarry
#

Yeah note it's the position you likely want to offset. The Transform represents position, rotation, scale, and hierarchy relationships.

#

you can also use spawnTransform.TransformPoint(offset) if you want it to be relative to the object's rotation and scale

Which is a very poor player experience.

#

That is what I said, yes

#

technically input handling should be in Update, and physics in FixedUpdate, but in this particular case for now it will work alright if it's all in FixedUpdate

safe root
#

Alright, thank you

#

If and when you add jumping you'll likely need to switch to a more robust separation between input handling and physics

When calculating difference

safe root
verbal dome
#

Yeah or do thiscs Vector3 desiredVelocity = moveDirection * walkingSpeed;

safe root
verbal dome
#

Try to understand how it works otherwise I'm just spoonfeeding you here

safe root
verbal dome
#

You have a target velocity, you calculate a difference from current velocity to target velocity.
If your current velocity is already close to the target velocity, the difference is minimal, and very little force is added.
If the difference is bigger, the force will be bigger

safe root
#

OH, I think I get it

verbal dome
#

It's like a rubber band

safe root
#

Yeah, it's kinda cool

verbal dome
#

Also don't multiply the difference with walkingSpeed inside AddForce

#

Multiply it with a separate float, like acceleration

#

It lets you control the 'snappiness'

#

The Pointer interfaces work with raycast targets, like the Image component here

#

Check to make sure you don't have another raycast target covering them up, it'll only call the functions on the topmost thing you're hovering.

#

If you select your Event System in the scene, at the bottom of the inspector is a little status window (you might need to drag the handle up to see more than a line of it). If you keep that visible while playing, it should display the name of the object you're hovering over

Like I said, use a different float to multiply the force so you can control the acceleration

If you're asking why you have to assign a value to a variable to use it, it's because what would you be referencing if you weren't referencing something?

This is the code for the movement of my character controller, but my character isn't moving in the direction that it's facing in. I know that this is due to the fact that the Vector3s are moving the player relative to the world and not to its own orintation. How can I fix this?

you need to transform your input into the direction the object is facing. you can do so by creating a Vector3 from the input then pass it through transform.TransformDirection

#

how can i add crouching in my game the best with the new input system? new action and adding bindings with modifiers?

swift crag
#

Either way, you only need to use one/two modifier bindings if you want to do something like

#

ctrl-A
ctrl-shift-click

hallow acorn
swift crag
#

Okay, so you'll make a new input action and call it "Crouch"

#

then add one or more bindings

#

You'll leave the action as the default kind -- "Button", rather than switching it to "Value"

your code does not turn the images on. the images are disabled.

hollow carbon
#

ok but when i able the image it will also show when i turn on the game

swift crag
#

then make your script enable the image

#

it's exactly the same as enabling the text

hollow carbon
hollow carbon
swift crag
#

you already know how to enable a TextMeshProUGUI

hallow acorn
swift crag
#

so you know how to enable an Image

hollow carbon
swift crag
#

e.g.

# 
PlayerControls.Floor.Move.ReadValue<float>();
#

this is reading a float value from your Move action

#

PlayerControls.Foo.Bar.IsPressed()

This will return true if Bar is a button action that's currently pressed

#

So, maybe, PlayerControls.Floor.Crouch.IsPressed()

hallow acorn
#

ok ty i try

hollow carbon
swift crag
#

Image is not image

#

capitalization matters.

#

you've declared a private field named image

hollow carbon
#

ah wait

swift crag
#

also, you'll need to give image a value

hollow carbon
swift crag
#

i would suggest adding [SerializeField] to those two fields so that they show up in the inspector

#

then just assigning them

polar acorn
hollow carbon
hollow carbon

# 
[SerializeField] private Image image;
#

or, equivalently

# 
[SerializeField] Image image;

fields are, by default, private

#

Get rid of this using line.

#

There are many places that declare Image

#

and your code editor can't know which one you meant to use

#

You want using UnityEngine.UI;

hollow carbon
#

how to deinstal it?

#

ok

swift crag
#

literally just remove the line

#

using allows you to use things without typing the entire name

hollow carbon
#

ok

#

before the game starts i have to make the image of the button invisible so that it only shows when i die

#

how do i do that?

swift crag
#

you already know how to make it invisible from the start, don't you

#

by disabling it

hollow carbon
#

yeah wait how can i upload a video

#

my englisch is not the best and its complicate

#

look

hollow carbon
swift crag
#

Show me your current code.

hollow carbon
swift crag
#

Drag the Image component into the field down here.

image.png
#

that's why we added [SerializeField]

hollow carbon
#

ahhh

swift crag
#

this shouldn't change anything, though, since you still had the GetComponent

#

you'd get an error in the console if the variable was null

#

One thing, though..

#

restard.enabled = true will do nothing, because the button was already enabled

#

Oh, and the button was already enabled!

#

So the if condition was never met

#

Disable the button in the inspector. It should start working.

hollow carbon
#

ok

the error: ```UnityException: RandomRangeInt is not allowed to be called from a MonoBehaviour constructor (or instance field initializer), call it in Awake or Start instead. Called from MonoBehaviour 'boutonJouer' on game object 'Image'.

#

as the error suggests, Awake or Start are often a good replacement

mb i have understand that

I see nothing wrong with using Awake

that's your problem
those Random.Range calls need to go in Start or Awake, as mentioned earlier.

#

as we said before

#

put them in Start or Awake

swift crag
#

Ah, I think I see a misconception

#

int random = Random.Range(1, 9);

fossil tree
swift crag
#

This does not mean that random will constantly get new random values

wintry quarry
#

not the variable declaration

swift crag
#

It's just running Random.Range(1,9) once and sticking the result in random

fossil tree

ohhhh ok ty

and show what printed

show code

#

I don't know what this means, this is just random

meager sentinel
#

i just placed it

#

If you have a sound issue it has nothign to do with this code or OnTriggerEnter

#

1st make sure there are no errors in console

#

second, double check you don't have audio muted or something

#

or that the volume is not just too low etc.

(you can, indeed, mute scene audio)

where did that question come from

#

am not very good at english tbh

swift crag
#

I don't think Play re-winds the audio

#

use Stop, then Play

#

maybe i'm just misreading the docs though

#

If AudioSource.clip is set to the same clip that is playing then the clip will sound like it is re-started. AudioSource will assume any Play call will have a new audio clip to play.

but one stays without working

Oh wait

hey, i have 2 animations and i need help with making them work on all characters. as in i have a sitting animation that should work fine but when i play the animation on my characters their arms go through their legs and stuff like this. i believe i need to do something that is called ik or something but i have no idea on how to do it. can anyone help

Ik that this may be a extremely stupid question, but someone knows or got a tutorial on how to make a sound not able to repeat anymore? I mean, when i do this and stop hearing the sound. If i get close again i came back to hear the same sound again, someone knows how to stop it?

You should only be setting it true when the coroutine first starts

dawn rampart
wintry quarry
#

it's literally in Update

#

think about it

#

isHit is true for the whole duration of the cooldown

#

so you're doing it every frame during that time

dawn rampart
#

ok that makes sense

wintry quarry
#

The cleanest way to do this would be with an event

#

but you can also have the SwordCollision script drive this interaction by calling a function when the coroutine starts

dawn rampart
#

after they do the animation

whole isle
#

so i added slimes into my game
when i attack them there health goes into negative but they dont disappear

polar acorn
#

Also, what calls RemoveEnemy()?

whole isle
#

😭

#

omg idk waht to doooo

wintry quarry
#

Seems pretty obvious - create the parameter

#

or make sure you spelled it correctly

#

etc

polar acorn
#

Also what calls RemoveEnemy()

wintry quarry
#

also make sure you actually call RemoveEnemy from somewhere. Is it happening in an animation event?

#

Don't just throw up your arms and give up. Check on everything

how can i make an equivalent of an oncollisionenter with the floor when im using a character controller? i have an IsGrounded bool which is a raycastspehre, but i want something to run once when they touch the floor (i.e. a ground puff)

wintry quarry
#

Sorry, fixed link^

#

you can also just do this with your grounded check though

#

e.g.

if (!groundedLastFrame && groundedThisFrame) {
  EmitPuff();
}```
stuck palm
#

thank you

whole isle
#

what do i do

wintry quarry
#

make sure the property getter returnt he backing field health and not itself Health

#

If you have it call itself you will always get a StackOverflowException

waxen adder
#

So I want the editor/game to abort if something goes terribly wrong. Right now, I have this:

public static class UnityShortcuts
{
    public static void Quit()
    {
        Debug.Log("Quitting...");
        Application.Quit();
        UnityEditor.EditorApplication.isPlaying = false;
    }
}

While it does close the game, it seems to do so only when the editor has already attempted what it was going to do. I want more of an emergency abort. As in, as soon as this function is called, we instantly quit out of the application. Is that even possible?

wintry quarry
#

only when the editor has already attempted what it was going to do
What do you mean by this?

whole isle
wintry quarry
#

What was it going to do?

wintry quarry
# whole isle ngl i dont understnad

Your current code is equivalent to this:

int health;

int GetHealth() {
    return GetHealth();
}```
What you want is this:
```cs
int health;

int GetHealth() {
    return health;
}```
#

properties are just functions

#

and you have a function that just calls itself, infinitely, until the computer runs out of memory.

whole isle
#

oh okk i think i understnad

#

so shall i change healthj

wintry quarry
#

you must change the property to return the field, instead of returning itself

waxen adder
wintry quarry

the only chance you have is force quit or attach a debugger and cause it to break out of the loop

you also have the same problem on line 20

pay closer attention

Do any IDEs warn about recursive stuff inside property getters?
I feel like they should

I'm kinda surprised intellisense didn't pick that up

You didn't save the scene

scene != assets

Those assets aren't in the scene

dammmmmm the tghing closed cauise of the overflwo error im pretty sure

if it crashed unity without save prob

timber tide
#

doesn't the scene save when you play though. I wouldn't know because I'm always saving

marsh glade
#

btw, the error is (mostly) in line 20. Your "get" for Health tries to return the value for Health, which tries to return the value for Health, which tries to return the value for Health,... creating an infinite loop

its fine guys learning experience

Good perspective!

rich adder
whole isle

eg . it helps knowing what a property is and why is it you're using it in the first place

marsh glade
# whole isle yh i cahnged it to health

Yes, but people were pointing to the fact that the mistake was in line 15, when the issue was actually in line 20. You can keep the "if(Health <= 0)" as is without creating an infinite loop as long as Health doesn't "get" itself

#

This doesn't create an infinite loop, although I wouldn't advise doing it

guys im so lost

after thje slime deleted everything all over thje place

like my sword animation dosent work now

#

does any 1 know where i canstart to fix this

rocky canyon
#

you're gonna need to explain More, you break down ur problem into smaller steps..
asking a question like that is too unspecific to get any real help..

thats like calling a mechanic and asking why your car "isn't running right"

#

why does the sword animation stop working..

whole isle
#

it started when i went on my movement code

#

made changed then it stopped working

rocky canyon
#

i'd start there and find out whats happening and work backwards until u see something you know doesn't work the way you intended it to

whole isle
#

so i can change that to start attack

rocky canyon
#

theres a warning there in the console..

#

maybe its the code controlling the animator?

slender nymph

^ if u think ur saving often enough, u probably need to save more often 😄

versions of your projects so you can go back if something messes up

rocky canyon
#

every day after u work on something important it gets uploaded to a server online..

whole isle
#

oh ok i see what u mean

rocky canyon
#

so if anything messes up u can revert it back to an earlier version

slender nymph
rocky canyon
#

for example

its basically your project folder.. theres programs that will pull and push (save and load) for ya

but yea, keep that in mind.. at some point when ur projects get big enough its something u'll wanna start using

You can find basic setup and tutorials on youtube.

yh i probs do need to add that

slender nymph
#

you should always use it

rocky canyon
#

if u try to learn it i'd use a blank example project

#

until u get it figured out

upper sphinx
#

Because if you push wrong you can overwrite stuff.

whole isle
#

guys i think the problem is somewhere here

#

it was working fine before idk what changed

#

wasnt like that before tho

#

😭

rocky canyon
#

well idk the exact problem, but u do have two if statements that are identical

#

did u know that?

whole isle
upper sphinx
#

So you Animator is trying to look for that parameter but its not there, Check your Animator

rocky canyon
#

^ thas the problem tho..

#

isMoving is not set up as a parameter in that Animation Controller

#

so when u try to call it, it doesn't exist and causes errors/ undesired behaviour

whole isle
slender nymph
#

you should be looking at the parameters list

upper sphinx
#

An good idea to do when working with Animations is to have the animator window pulled aside and run the game as you watch the animator,
What are your paramenters in the controller.

whole isle
# whole isle

in the code i wrote its moving should it not be player walks cause that what it called in my animaotr

rich adder
rocky canyon
#

parameters are on the left there.. you have to create it, bool, trigger, etc and use it as a transition or w/e

#

you create it and name it.. but it has to match w/e u reference in the script

#

if u use isMoving in the script make sure ur parameter is called isMoving

  • IsMoving
  • is Moving
  • etc are not the same
whole isle
#

i just closed unity and re opening it lol

#

but imma go check

small gull

how would i set a rigidbodys velocity to 0?

wintry quarry
slender nymph
#

do you know how to assign to the rigidbody's velocity?

small gull
slender nymph
rich adder
small gull
#

rb.velocity = 0?

whole isle
rich adder
slender nymph
# small gull rb.velocity = 0?

almost. rigidbody.velocity is a Vector3 or a Vector2 depending on the type of rigidbody you are using. so you need to create a vector that is all 0

rocky canyon
whole isle
#

instead of starting the game when im idle my idle animation is the walking animaiton

small gull
rocky canyon
#

u need to mark ur idle animation as the Default starting animation.. (it should be orange)

#

and then u transition into ur movement clips

whole isle
#

OMGGMG NOW IM WALKING IN THE IDLE ANIMATIONM

rocky canyon
#

Set as Layer Default State, thats how I commonly do it.. i'll create an Idle animation.. or for hard surface things, like a blender for example, my idle animation will just be a single keyframe and then i'd transition into the "running" animation

whole isle
#

yh it like that

rocky canyon
#

sounds like a transition problem

#

make sure ur clips are transitioning to the clips they should be..

#

and if not.. check the transitions/ the parameters, and the coding

#

if its not an error in the code then it'll most likely fit better in #🏃┃animation once u start getting into the editor stuff

whole isle
#

k i fixed it

#

and i feel like an idio

tender stag
#

in DetermineHeadbob() on line 64 i set the target amplitude and frequency according to the movemenet type, but it changes instantly when i switch the movement type, i tried like smoothing it on line 82 - 83, and then on lines 92 - 93 i tried replacing the target values with smoothed values, but it gives me weird results, so should i smooth the offsetX and offsetY instead?
https://hastebin.skyra.pw/difipawexe.csharp

stuck palm
#

is there a better way to do this? i think finding objects of type is kinda ass but its meant to account for new joining players

void Update()
    {
        PlayerScript[] players = FindObjectsOfType<PlayerScript>();
        
        if (players.Length == 0) {return;}
        foreach (PlayerScript player in players)
        {
            if (player.ID == playerID)
            {
                rt.position = _camera.WorldToScreenPoint(player.gameObject.transform.position + offset);
            }
        }
    }
slender nymph
#

instead of using FindObjectsOfType every single frame, which is a pretty expensive call. just have the newly joining players register themselves with this component on join

tender stag
timber tide
#

doing that in update is probably the worst way to utilize that

tender stag
#

have like a method OnPlayerJoin and OnPlayerLeave

#

or something

rocky canyon
#

yup, as u work think does this make sense to be running every frame

#

super simple optimization hack

CC does lot of stuff for you, rigidbody just simulates physics. Rb requires quite much of code to get character behaving correctly unlike CC which is made just for it

rigid sage
#

can you make momentum based movement similar to sonic frontiers with CC?

summer stump
verbal dome

Catlike coding has some text tutorials for RB movement. Haven't checked it much but their tutorials are usually decent
https://catlikecoding.com/unity/tutorials/movement/
If you want a video tutorial, I can't remember a decent one off the top of my head.
That being said, like Aleksi said, RB movement can get complex and you should get familiar with Vector maths

CC is easier to get basic movement fast
