[lofty canopy]

You could use GameObject instead of Transform but in most cases you work with the Transform. Setting it as GameObject just creates an extra step to get to the transform.

[balmy vortex]

It doesn't actually rotate though?

or like wdym

[lofty canopy]

are you rotating the parent gameObject?

[naive pawn]

which object is the camera attached to

[balmy vortex]

the "Head" game object

[lofty canopy]

Looks like a cinemachine camera nested in the player.

[naive pawn]

then you would have the anchor as a child of Head

that's the one that's rotating, right?

you would have the anchor rotate with it

[lofty canopy]

Can I see your CinemachineCamera settings?

[balmy vortex]

is there any reason why making the spawn point a child of the camera itself is a bad idea

cuz like it works but it seems like the kind of thing I probably shouldn't be doing

[lofty canopy]

@balmy vortex can I see your movement script and cinemachinecamera inspector settings?

[balmy vortex]

movement script https://paste.mod.gg/owdyfcqfbknc/0

camera

[lofty canopy]

Which camera do you have set as the _camera variable?

[balmy vortex]

the main camera, why?

[lofty canopy]

That's not adviced since the CinemachineCamera gameobject controls the main camera. Think of it adding a brain to the main camera and it manipulates it.

You should rely on moving the Head gameObject since the CinemachineCamera is following it.

I'd also advise grouping the CinemachineCamera with the main camera both nested in a parent gameObject for organisation purposes.

Because the camera is just for capturing the scene in most cases. You would be better to child it to the Head like someone previously said.

void Start()
    {
        distToGround = GetComponent<Collider>().bounds.extents.y;

        move = InputSystem.actions.FindAction("move");
        jumpAction = InputSystem.actions.FindAction("jumpAction");

        move?.Enable();
        jumpAction?.Enable();

    }

btw, I changed your null checks and add the ? so it will try to enable it if it isn't null.

Reference for you: https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/member-access-operators

[sour fulcrum]

though in 99% of cases you shouldn't use ?

[lofty canopy]

Really? I wasn't aware of that.

[sour fulcrum]

you shouldn't use them on anything deriving from unity's Object

[lofty canopy]

Ah ok, noted. Cheers.

[sour fulcrum]

they can't overload ? so in some cases (usually relating to object destruction) that check is not reliable

[grand snow]

using it on an input action is fine but in the above example seems bad because the action will surely need to be used elsewhere

[wooden fiber]

yo anybody got experience with Unet?

it displays black objects that i can phase through

[grand snow]

Unity 5 is 10+ years old, any reason why you are using it?

[wooden fiber]

my pc sucks

[sour fulcrum]

godot time

[wooden fiber]

i prefer unity tho

[sour fulcrum]

i think once you spend abit more time using unity 5 + unet with no support you might change your mind 😛

[grand snow]

newer unity versions are probably better anyway as you can remove packages from projects and use more efficient renderers for low end hardware

[balmy vortex]

hey so like how do you delete excess projectiles like this without nuking their prefabs?

Here's my spawner and prefab code for context
spawner --> https://paste.mod.gg/edzuzqzszrit/0
prefab --> https://paste.mod.gg/ffjzxkiutsqb/0

[wintry quarry]

There's no reason to "nuke the prefab" and doing so wouldn't delete the projectile in the game anyway

To destroy objects in Unity you use the Destroy function

[grand snow]

This would be a good place to use object pooling however

after x amount of seconds, disable projectile and add back to pool

https://docs.unity3d.com/6000.2/Documentation/ScriptReference/Pool.ObjectPool_1.html

[balmy vortex]

yes but idk where to put it cuz if I put it on the prefab itself to carry over to the copies the prefab also gets deleted with them

[wintry quarry]

Right now you're just calling Instantiate and ignoring the return value of it.

Instantiate actually returns a reference to the object it creates. You can store that reference, in a list for example, then you can do things with it later.

[wintry quarry]

What do you mean

[sour fulcrum]

you destroy the instance not the asset

[wintry quarry]

"put it on the prefab" is vague

[balmy vortex]

oh well how do I do that then?

[balmy vortex]

the prefab script

[balmy vortex]

shown here ^

[wintry quarry]

The script on the prefab itself will not be running code like Start etc

So that would not destroy the prefab

Only instances

E.g. if you called Destroy(gameObject, 5); in Start it would work fine and only destroy the instances

Alternatively, you handle them from the spawner

[balmy vortex]

wdym

[balmy vortex]

well how do I do that?

[wintry quarry]

Show what code you put for that

[wintry quarry]

Wait I see your problem

[balmy vortex]

https://paste.mod.gg/ljkxhidrgoau/0

[wintry quarry]

Why do you have your "prefabs" in the scene?

That's not how prefabs works

You need to drag those from the scene into your asset folder then delete the copy in the scene

[grand snow]

Oh wow yea, some critical miss understanding happening right now 😐

[wintry quarry]

Then have your spawner reference the prefab from the asset folder

Then it will work fine

Because you'll actually be using a prefab

[balmy vortex]

the copies have their references removed when spawned like this though

[grand snow]

you need to init them post spawn then with these references

but why does it need the player and camera transform?

(using a prefab asset is the correct thing to do)

[balmy vortex]

player body to get the players position to despawn itself after it goes a certain distance away from them
camera to know what direction to move in

the former is probably redundant now but ya

[balmy vortex]

ok well how do I do that?

[grand snow]

Get the component and assign to the variables

Make them public to do that.
Or add some function to assign this data

[grand snow]

FireballScript? You tell me you made it

If get component confuses you then please read up on it it's very important

[naive pawn]

i don't think the ? is good here, it will make it fail silently instead of failing fast

[lofty canopy]

I did mention it earlier.

I posted a Unity learn link for it @balmy vortex

[lofty canopy]

Someone corrected me earlier. Not sure what you mean by "fail silently" and "failing fast" or the repercussion of either. Could you please elaborate?

[naive pawn]

if one of the actions there exists but you mistyped it, ? will mean that you don't get errors, but you will get bugs instead due to the intended action not getting accessed

letting it fail fast and generating an error message instead of trying to continue would let you catch that mistake

[foggy yoke]

Hey! I have some ScriptableObjects that I need to load on Awake. I tried using Resources, but that freezes the game, even with only three ScriptableObjects, so I’m looking for a better approach.

[keen dew]

Why do they need to be loaded specially instead of just assigned to fields?

[foggy yoke]

Because I'll have many of these scriptable objects, and I don't want to manually assign every one of them

[sour fulcrum]

Have one scriptableobject hold references to the others 😄

Then you only need to assign one in scene

But you may still run into that freezing, loading data is still loading data

[keen dew]

Or make an array and drop all of them there. Takes less than 2 seconds.

[foggy yoke]

Let me try this one, and see if it works for me

[sour fulcrum]

I have a

public class ScriptableManifestManifest : ScriptableManifest<ScriptableManifest>

From doing this myself lol

[foggy yoke]

Well it doesn't work because I have an interface that I reference, and all of my scriptable object inherit from this interface.

[keen dew]

Wouldn't that make it work better because they share an interface?

[sour fulcrum]

Can’t serialize interfaces

[foggy yoke]

Yep

[sour fulcrum]

Are you sure resources was causing that freeze?

[foggy yoke]

Yeah, I removed the loading part and it was working fine

[sour fulcrum]

Been abit since ive used it but it shouldn’t be causing a notable stall with that light of a load

Stuff like photon still rely on using it nowadays

[foggy yoke]

Wait actually no.... it doesn't cause a freeze now.

so something else is causing the freeze

[sour fulcrum]

i will accept my 10 morebillion dollars to my paypal 😄

[foggy yoke]

sure

[alpine fog]

you can change it to be Addressables instead of Resources, if you're referencing prefabs inside the SOs and they're large then that's possibly what causes it to slow down. Change the prefab reference to be an AssetReference so the prefab isn't loaded when you load the SO and you only load it when you need it. With addressables you can also load locations or the SOs themselves async as well which might help and only load the data you actually need instead of everything right away

[foggy yoke]

I've tried to use Addressables, but the unity doc says that it is unsupported

[alpine fog]

what's unsupported?

[alpine fog]

what unity version are you using?

[foggy yoke]

6.1

[alpine fog]

no way addressables are unsupported on 6.1

[sour fulcrum]

6.2 just came out so its yappinh

Addressables is fine and recommended

[alpine fog]

the doc itself is just old and prefers you refer to 6.2 docs instead of 6.1

[naive pawn]

it's saying the unity version is unsupported by unity

nothing to do with addressables

6.1 was removed from the "supported" group when 6.2 came out

[foggy yoke]

ohhh okay.

[keen dew]

You can also serialize them as ScriptableObjects and then cast to the interface

[foggy yoke]

I'll try the addressables approach and then come back if it didn't work.

[grand snow]

ask in #📦┃addressables if you need help and ill maybe answer 😆

[foggy yoke]

The addressable approach does work, but I have to rename the addressable name to perk by hand.. Isn't there a better way?

[wintry quarry]

I question the assertion that Resources.Load freezes your game btw 🤔

do you mean there's a hiccup, or a full freeze, or what?

[foggy yoke]

The game doesn't respond for a second, but I figured out that it wasn't caused by resources.

[wintry quarry]

yeah I would say make sure you use the profiler

[foggy yoke]

The what?

[wintry quarry]

The profiler - it's a tool for measuring performance and will let you see what causes any particular slowdown

[foggy yoke]

ohhh. is it like a package or asset?

The cpu exceeded my target frame time...? that's what's causing the freeze, i just don't know how to fix it

[wintry quarry]

It's a built in tool in the editor

[foggy yoke]

yeah i found it

[lofty canopy]

@foggy yoke make sure you enable "Deep Profile" and change it from Timeline to Hierarchy for easier viewing. 🙂

Resource: https://support.unity.com/hc/en-us/articles/210223933-How-can-I-profile-a-specific-part-of-my-code

[foggy yoke]

well unity crashed..

[lofty canopy]

How? did it just stop responding or actually closed and loaded an error window?

[foggy yoke]

yeah.

yaayy

[lofty canopy]

Which one? If it stopped responding the entire app would just go white.

[foggy yoke]

it did, and it showed the bug report window

[lofty canopy]

That could indicate a infinite loop or something close to it.

[lofty canopy]

You can add using System.Linq; and use List<ScriptableObjectScriptName> scriptableObjects = new List<ScriptableObjectScriptName>(); or you could [SerializeField] it.

They're easier to work with than arrays, imo.

[foggy yoke]

I've fixed that part.

Thank you

[lofty canopy]

Ah ok, sorry. Catching up.

Do you have an idea what's causing it to freeze?

[hot wadi]

Do u guys know how to fix this bug? I think it's related to the VFX asset I imported
TransientArtifactProvider::GetArtifactID call is not allowed when transient artifacts are getting updated

[lofty canopy]

This is the best I could find. Hopefully someone else may have a better solution.

[slow blaze]

I have a rectangle where my arena is, how do I make it so that the camera only captures the inside of the arena regardless of screen size?
Since resizing seems to make it zoom in or out

[hot wadi]

Definitely an odd bug. I have not done anything, but it's gone

[lofty canopy]

You could create two empty GameObjects called "Left" and "Right" and use Cinemachine and Cinemachine TargetGroupCamera for dynamic zoom.

[slow blaze]

for a 3d it wouldn't be much different right? Maybe two objects on the corners

[lofty canopy]

You can add more than two targets for the group i.e. 4 and adjust their positions and the weight on the component.

So, you could create 4 gameobjects representing screen origin { 0,0 - 1,0 - 0,1 - 1,1 } or name it whatever makes sense.

[scarlet skiff]

does the SO class have to have its own file or something?

[slow blaze]

I can't find the componenet Cinemachine for some reason

CinemachineTargetGroup

[lofty canopy]

It's a package you have to install through package manager. Maybe watch a Youtube vid on Cinemachine. It basically gives the main camera a "brain" so to speak.

Oh, new using for Cinemachine is using Unity.Cinemachine; I believe.

[slender nymph]

Yes, it must be either the only object declared in the file or the one that shares a name with the cs file itself in order to work in the editor. the same is true of components like the NetworkBehaviour you've defined in that file which is why that works but the other does not

[lofty canopy]

Would you recommend he remove the serializefield and make the scriptableobject field public and move the class to another file of the same name as the class?

[slender nymph]

Would you recommend he remove the serializefield and make the scriptableobject field public
no

unless they need to access those variables outside of that class it should be private

[lofty canopy]

How would he access them from the public ItemPickup creating a public ItemData variable?

[slender nymph]

currently they are not accessing them from that object, just an instance of the SO. presumably they will be adding relevant methods or properties to the SO to access or modify its state

[lofty canopy]

Oh yeah, duh. getters and setters. 🙂

Thank you.

[scarlet skiff]

i think i made em as such out of habit, this inventory system differs from what ive made before so im just working and seeing how it goes and change stuff when i need, also thanks

then link to it again in that channel providing a quick overview of what you need help with

[fallen cosmos]

I dont know what everyone else does for this, thats what I am asking in that thread

[slender nymph]

not a code question. but the collider and mesh should be separate objects so that you can adjust everything to match the mesh's pivot of being at its feet

hey so like I'm trying to set this --> [SerializeField] public Transform _camera; on my prefab but when the prefab copies itself it doesn't carry over the _camera reference, leading to an error.

[hot wadi]

GameObject.FindWithTag

[rich adder]

var myInstance = Instantiate(etc.. myInstance.SetCamera(myCam)

[slender nymph]

a few things to note here:

1. prefabs cannot reference scene objects, so it's likely referring to a camera prefab which is not in the scene (or just nothing at all)
2. you don't need both public and the SerializeField attribute, public variables are serialized by default
3. rather than relying on a reference to the camera just put a method on the FireballScript that takes the desired direction and have the spawner pass that in immediately after instantiating it
4. FireballScript is a bad name, it's obviously a script you don't need to include that in the name

[rich adder]

yea no reason to pass an entire camera here, just pass what you need from camera directly

[balmy vortex]

rather than relying on a reference to the camera just put a method on the FireballScript that takes the desired direction and have the spawner pass that in immediately after instantiating it
how do I actually do this though?

[slender nymph]

Instantiate returns a reference to the object, so store that in a local variable and call the method on that local variable

[rich adder]

var myInstance = Instantiate(etc.. myInstance.Init(dir);

[lofty canopy]

@balmy vortex did you watch some YouTube vids on Cinemachine? I think that would help you understand a bit more about what you're trying to achieve.

[primal trench]

does anybody have any resources on SendMessage()?

[rich adder]

what send message are you talking about, there are multiple

[slender nymph]

the best resource of them all is this single sentence: "Don't use SendMessage"

[hot wadi]

Just go to Unity Scripting API

[primal trench]

hm? why?

[rich adder]

if its Input System its okay..just upgrade later

[primal trench]

like how do i use send message myself

[slender nymph]

because it relies on reflection and simply getting a reference to an object and calling the method you want directly is so much better

[rich adder]

are you talking about the Input system one or MonoBehaviour?

[primal trench]

i want to do what the input system des in the terms of sending out a message to other coimponents but in my own script

[rich adder]

yeah don't do it that way.. its not good

[primal trench]

ah....

[slender nymph]

either get a reference and call the method directly or use an event

[rich adder]

for Input System its okay to learn, but you should do references for components

[primal trench]

well now that you mentioned it what's wrong with using it with input

[slender nymph]

pretty much every other way to receive input from the PlayerInput component is better than SendMessage

[rich adder]

similar issues but its imo acceptable to learn the basics, its quick way to get Input system going but you should learn Unity Event at least if not actual Action events

[primal trench]

why's the playerinput compoentn exist then

[rich adder]

to make it easier on you

[slender nymph]

SendMessage isn't the only option for the PlayerInput component. nobody said anything about not using it, even though not using it is also an option

[primal trench]

is 'broadcast messages' better>

[rich adder]

You don't have to use it though PlayerInput, you can perfectly just generate a C# script from input map and use those

[slender nymph]

that's basically the same thing but for multiple objects which probably means it's actually worse

[rich adder]

start with Invoke Unity Events it will be the most familiar to you

[primal trench]

ok

[rich adder]

if you ever used a UnityEvent or similiar like Button OnClick its like that, link a script/method and you get the CallbackContext

[primal trench]

if all this is the beginner method how am i supposed to be doing this

[primal trench]

I'll go do that then!!! ^_^

[rich adder]

check these they are very important
https://docs.unity3d.com/Packages/com.unity.inputsystem@1.5/manual/Actions.html
https://docs.unity3d.com/Packages/com.unity.inputsystem@1.0/manual/Interactions.html

[primal trench]

just real quick- if i have this code

        {
            PlayerGrapple.StartGrapple();
        }```
how would i translate this to callback

just as example

[rich adder]

https://docs.unity3d.com/Packages/com.unity.inputsystem@1.5/manual/HowDoI.html

you see the InputAction section for example fireAction.performed += Fire;

[balmy vortex]

how do I actually pass the direction along to the copy though?

[slender nymph]

put a method on the FireballScript that takes the desired direction and have the spawner pass that in immediately after instantiating it

[balmy vortex]

yes how do I do that?

[rich adder]

#💻┃code-beginner message

[slender nymph]

you do that by creating a method on the FireballScript that takes the desired direction. then you can have the spawner object pass that direction in by calling said method directly after instantiating it.

[primal trench]

So in void update I'd do like, GrappleAction.performed StartGrapple?

[slender nymph]

you would only subscribe to the event once, not every single frame

[rich adder]

did you click on the links I sent lol

[primal trench]

I tried

[rich adder]

it explains everything in and out

[primal trench]

ohhh i see

can I still do like, ctx.isPressed>

[balmy vortex]

what's (dir) supposed to be here?

[slender nymph]

that would be you passing the desired direction as an argument to the method. which is the entire fucking point here

[rich adder]

the direction you want your prefab to use

so it can do transform.forward = dir

[balmy vortex]

kk

[rich adder]

CallbackContext doesn't have isPressed

[primal trench]

what does callbackcontext do then?

[rich adder]

information callback about the action you triggered

from the docs here is example for a tap shot vs a charged shot

void FirePerformed(InputAction.CallbackContext context)
{
    // If SlowTap interaction was performed, perform a charged
    // firing. Otherwise, fire normally.
    if (context.interaction is SlowTapInteraction)
        FireChargedProjectile();
    else
        FireNormalProjectile();
}```

this is what I was explaining yesterday about how you can switch this from Held shooting to Tap shooting

[primal trench]

alr, so it'd be like Context.interaction is Pressed?

[rich adder]

idk why you keep mentioning Is Pressed lol its not relevant here

isPressed comes from if you use InputValue

[primal trench]

so like if i have my input to trigger with bossed pressed and released how do i check in the code if that interaction was from a press or from a release

[rich adder]

like I mentioned before, you have the started and canceled performed states

canceled is usually when you "let go" of the key

[primal trench]

so contect.interaction is started?

[rich adder]

You realize these are like examples? you have to create these methods and not copy verbatim

[rich adder]

you either subscribe a method to specific action state or you check it within the method with CallbackContext

test it out first so you can get an idea of what its doing..

put the Unity event like I showed . You see whats called by default mode button with no Interactions mode set.

 public void OnFire(InputAction.CallbackContext context)
    {
        Debug.Log($"started {context.started} or canceled {context.canceled}");
    }``` 
you will see it gets called 3 times

Started being True, then Started being False and Canceled for let go
or Performed will run when it has done the singlePress instead of the initial press

[primal trench]

then do i still need to have all the stuff in on enable and stuff that it shows in the unity docs example or do i just need the functions and the invoke unity events on the player input

[rich adder]

the .Enable stuff is if you deicide to instead using the ActionMapClass instead of PlayerInput component

InputAction too iirc but I haven't used that

[primal trench]

one last question- how do i get the vector2 of stuff like the mouse and movememnt inputs

the docs didnt talk about that (that i could see)

[lofty canopy]

Input.mousePosition?

[grand snow]

you can access the mouse devices OR make an input action that you can use

[lofty canopy]

Oh, sorry, you're using the new input system.

[grand snow]

the ideal way is to use an input action if you desire mouse and controller inputs to work

[rich adder]

eg

public void OnMove(InputAction.CallbackContext context)
    {
        Debug.Log($"v2 {context.ReadValue<Vector2>()}");
    }```
if using UnityEvent mode for example

[primal trench]

oh it's the same! Okay! I think im ready

[naive pawn]

if you want to just test or bodge before getting the right actions, you can check controls from Mouse.current

but something like what nav suggested (for example) should be your final solution, as it'll be easier to work with

[primal trench]

I can't seem to find a callbackcontext type

[rich adder]

make sure you have the using using UnityEngine.InputSystem;

[primal trench]

i do

[naive pawn]

do you have the InputAction.?

[rich adder]

its nested in the InputAction

[primal trench]

that's the issue

thanks

[naive pawn]

CallbackContext isn't a free class, it's nested inside InputAction
so you need either that or a using static UnityEngine.InputSystem.InputAction.CallbackContext;, i think would be the usage...

[rich adder]

yeah that works too

[slender nymph]

you're one level too deep for the using static there i think

[rich adder]

ah yeah just using static UnityEngine.InputSystem.InputAction;

[naive pawn]

whoops, was thinking of the using static X = Y; thing

[primal trench]

if (ctx.interaction is ctx.started)
isn't right- what's the right way? So sorry for all the questions

[naive pawn]

started is a boolean on the ctx itself

you might be thinking of phase, which is an enum

[rich adder]

interaction actually afaik is a Interface for Interaction type

[naive pawn]

(yeah i misread there at first, whoops)

[rich adder]

as per unity example here i posted #💻┃code-beginner message

[rich adder]

might help if you explain what are you trying to implement this exact moment, instead of guessing it lol

[primal trench]

im trying to check if the interaction is astarted or canceled interaction

so i'd do if (ctx.started) ?

[rich adder]

I showed you here
#💻┃code-beginner message

[naive pawn]

those aren't interactions

started/performed/cancelled are phases
interactions are hold, tap, slow tap, multitap, release, etc

[rich adder]

also How and What button mode / interactions play a difference in phases

[primal trench]

then i need to check if the interaction that was performed is a press interaction or a release interaction

[rich adder]

canceled is released

[primal trench]

        {
            if (ctx.started)
            {
                PlayerMovePlayer.StartSlide();
            }
            else if (ctx.canceled)
            {
                PlayerMovePlayer.StopSlide();
            }
        }```
so this?

[rich adder]

 public void OnFire(CallbackContext context)
    {
        Debug.Log($"started {context.started} performed {context.performed} canceled {context.canceled}");
    }```   put Log in your method you can test it yourself what the phases are doing

and see how Interactions affect that behaviour

[neon forum]

Is there a button.OnPointerHover event or is that only a function?

[rich adder]

you mean this
https://docs.unity3d.com/2017.4/Documentation/ScriptReference/EventSystems.IPointerEnterHandler.html

[neon forum]

ahh

[rich adder]

that goes directly on the element though

[neon forum]

how do I make it go directly on the elemtent?

[primal trench]

it worked :D tysm!!!

[rich adder]

put the script shown in the docs on the actual button

[neon forum]

oh yeah that's already apart of the button. Are there any other steps I need to perform or will it auto function?

[rich adder]

it should already function if you have EventSystem in the scene

[neon forum]

I do

yeah it works, ty.
Quick question though, is it possible to have another script listen for when the OnPointerEnter occurs? Or is that not possible since it's not an event

[rich adder]

tbh I don't think so, but what I usually do is create a separate event for what I want, hover, click etc.
public event Action<Button> OnPointerEntered

[neon forum]

And unity/c# will know what I'm talking about?

[rich adder]

well if you subscribe to specific event from somewhere else it will

like myButtonScript.OnPointerEntered += ButtonWasHovered

or use intermediary objects

[neon forum]

don't I need to add an event listener?

[lofty canopy]

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

[naive pawn]

you would have that other script listen

that's exactly what myButtonScript.OnPointerEntered += ButtonWasHovered does

[rich adder]

+= subs a method as listener

[neon forum]

ahh

[acoustic belfry]

Hi, what i did wrong? i was testing and my melee doesn't storage the enemies, i mean, it is constantly Hurting it nonstop, instead of just hurting it once until AlreadyHitDemons is cleared

   {
       Debug.Log("meele's call'd yeah");
       Vector3 meleeRange = new Vector3(attackRangeX, attackRangeY, attackRangeZ);
       int hitsCount = Physics.OverlapBoxNonAlloc(meleePos.position, meleeRange, hitDemons, Quaternion.identity, demons);

       for (int i = 0; i < hitsCount; i++)
       {
           Debug.Log("int is not zero, i guess");
           Debug.Log(hitDemons);
           if (hitDemons [i].TryGetComponent<EnemyBase>(out var enemy))
           {
               Debug.Log("THIS SHOULD WORK");
               enemy.TakeDamage(meleeDamage,0,2,2,transform);
               // Don't set HasHitValeria = true here if you want to hit all targets
           }
       }
   }```

[naive pawn]

that's not a lot of context to go off of

[red igloo]

I have this issue where when I look around I can see my own player body any ideas why?

[naive pawn]

where should it be "storing" the enemies?

i don't see any AlreadyHitDemons there

[acoustic belfry]

huh, looks like due the noalloc part made me forget abt it, yeah, makes sense

well, i will add it now, thanks

[rich adder]

looks like some offset rotation issue

[rough granite]

was thinking more so the cameras position but yeah

[primal trench]

question somewhat related to what i said before, since messages are bad, can i do what the input actions does with the invokation stuff but with my own script and own behavior? like let's say i have an "interactable" component and i want the interactable to invoke "interacted" with a door component

[naive pawn]

yeah

if you couldn't, how would the inputsystem be able to

[primal trench]

is there a way to lerp position, rotation, and scale all at the same time in code?

[naive pawn]

no, computers do one thing at a time

[primal trench]

could i do it with coruoutines?

[naive pawn]

you can do them in sequence within the same frame and it'll all render out at the same time

[primal trench]

or is that bad practice

[primal trench]

oh alr

thanks

[naive pawn]

no im saying the operation you're asking about doesn't make sense

but a slightly different operation is a no-brainer

[west stag]

youre being obtuse rn chris

[west stag]

@primal trench this answers your question

[naive pawn]

this is an important thing to note in terms of mindset

unless it's a math thing where you can compound operations, then no, you can't do anything at the same time

but computers are fast enough that doing them one thing at a time can look like they're at the same time to a human observer

[primal trench]

when i do them one after another vscode says "assigning position and rotation sequentially could be optimized"

[west stag]

show ur code

[naive pawn]

well, see what it suggests then

[slender nymph]

it's probably referring to using the SetPositionAndRotation method instead of assigning to the properties individually

it's more "optimized" to use that method if you need to set both because it only ends up being a single call into native code instead of two separate calls into native code

rn when my player ledge jumps they have to be holding D, i also want the option for them to be holding A to jump left which means a negative velocity. is there any efficient way to do this without creating another if statement and coroutine?

[grand snow]

have an arg be the direction as a vector?

I havent opened your code but i presume at some point you will apply force

[sharp mirage]

nah im using velocity

[grand snow]

either way you can add a vector to the velocity or assign the new vector as velocity

Jump(new Vector2(-1f, 0f))
Jump(new Vector2(1f, 0f))
yay any 2d direction

[sharp mirage]

not sure how id implement that into my own code ngl

[grand snow]

okay ill check yours then

but it should be trivial to have some input direction for force

Ah its very funky

[sharp mirage]

tbf the only thing u really need to concern urself with is the ledgey function and booster coroutine

[grand snow]

It may be easy to do as you can invert some force by doing * -1

[sharp mirage]

when A is pressed or?

[grand snow]

Perhaps you should instead read horizontal input instead of the D key, if its length is not 0 you can perform the jump (if its direction is away from the wall)
This input dir can also be used to produce the move velocity?

Is it possible to know if the ledge is on the left or right currently?

[sharp mirage]

nah cuz u can ledge jump if either ray is touching it if thats wym

[grand snow]

Basically the logic to jump off needs to be changed to be usable for both conditions and therefore should not be hard coded for one of the two.

Lets go back, is this currently set up to only let you jump right?
else if (Input.GetKeyDown(KeyCode.Space) && LedgeTime > 0 && Input.GetKey(KeyCode.D))

[sharp mirage]

yeah thats how i can ledge jump

i could create another if statement for when A is pressed but there has to be an easier way is what i was thinking

also im not familiar with horizontal input reading

is that the input.getaxisraw stuff

[grand snow]

Then look at Input.GetAxis() first

We can use this to detect horizontal input AND know the direction of it (-1 x or 1 x)

[sharp mirage]

seems pretty simple

[grand snow]

And ideally this direction is also used to perform the ledge jump but you will need to verify that this jump is possible so they dont jump into the wall

[sharp mirage]

the ledges have 2 triggers like so

ray looks like this

[grand snow]

Perhaps you should just configure on the ledge if its a left or right ledge

[sharp mirage]

wdym

[grand snow]

e.g. have a new script called "Ledge" and have an enum on it to specify which side the ledge is on

Or we figure it out another way based on how its placed or some other data

[sharp mirage]

i mean that type of object is always gonna have 2 ledges

[grand snow]

Then how do you think we can tell which direction the player can jump from a ledge?

[sharp mirage]

ur right

i did not think abt that that makes things alot more complicated

[round mirage]

Hello i am trying to make a dynamic inventory. Everything works perfectly but i have 1 issue 🥲 when i take an item in a slot i cant replace it in the exact same slot, I have to place it in an other slot and then place it again in the previous slot. but the weird thing is that i am using a function remove() called everytime i do this and i press Escape. it work perfectly for escape but not for the other thing. I've been looking for 3 days but i found nothing 😢 (parts i used for this feature are between "***")
invManager : get inventory slot and know if an item is already inside (he's the link between all slots)
slotScript : it is the script inside every slot
DragScript : it is the script who add drag & drop to every item

sorry it is a lot of code 🙂

[grand snow]

There are a few ways to go about it but its useful information we need for a ledge to then ensure a ledge jump is done in the correct way.
A script for the ledge with this data may be easiest (e.g. public Vector2 jumpDir;)

[sharp mirage]

What would I do with jumpdir

[grand snow]

we can use it to confirm if the input direction is correct AND can be used as the dir to push the character
e.g. AddForce(jumpDir * multiplier)

Hey I have to use a timer for my enemy behaviour, i have seen that C# itlsef has an TIMER class, can i use that or will that cause problems with my unity project

[west stag]

dont use that

[slender nymph]

pretty sure System.Timers.Timer invokes its events on a separate thread so you wouldn't really want to use it for unity stuff

[shadow field]

aight thanks!

[west stag]

use time.time and math in an update loop tbh

[shadow field]

yes that's how i have done it so far, it works but i notice how repetitive it is. espacially if you have to do it multiple times in one script

thinking about creating an helper class which I could use more often

[sour fulcrum]

I have a little base class that basicially wraps up a coroutine

[ivory bobcat]

Depends on your needs and how you've implemented it.

[shadow field]

I think it wont be the last timer im gonna use for an unity project, should be worth it

[shadow field]

yee was thinking about something like that

that would work with a static class/method right?

[sour fulcrum]

i dont use statics for any of this no

[shadow field]

ahhh yeah fair because I would like to have an reference to the timer i just started

[grand snow]

A coroutine or async function is the way to go

[west sonnet]

I have a ray pointing forward from the camera, and I want to be able to detect the type of object I'm looking at (eg, weapon, food, etc). How can I get information of the object using the Ray?

I'd want to get the layer or tag

[sour fulcrum]

Raycast with layermask for initial collision, then use TryGetComponent on the RaycastHit result object to see what it might be

if (Raycast)
if (hit.TryGetComponent(out Weapon weapon)

eg pseudocode

[shadow field]

or if your objects dont have individual components you could go by the tag of the gameobject:

if( hit.transform.gameobject.tag == "food")
{
dostuff
}

[sour fulcrum]

This is true but ideally it’s worth skipping over tags entirely tbh

(Note ideally)

[rich adder]

1. tags are trash
2. you should not use == , CompareTag is better

[shadow field]

yea CompareTag didn't know the syntax out of my mind thanks, and I believe for protyping it gets the job done

[rich adder]

https://docs.unity3d.com/ScriptReference/RaycastHit.html

[sour fulcrum]

No shade here but once you get in the habit of it it doesn’t cost any additional time you’d save in prototyping. The idea here is that tags are hardcoded and a kinda arbitrary middleman. The conponent check doubles as a tag check if you treat components like tags

Many documents and tutorials use tags which is why people get that habit but it really just doesn’t bring anything to the table

[shadow field]

i mean it works lol 😅

[grand snow]

I never use tags and the only reason id think to use them is to perhaps speed up component retrievals

[sour fulcrum]

At that point i’d even prefer the unholy strat of using physics materials as object references for identification 😛

[west sonnet]

Does anyone know why I can't see a Ray being projected? I know my ray is working because I have a "Debug.Log()" that says whenever an object is hit by the ray, but I can't actually see the ray in the scene view

[shadow field]

ok lets get the plumb things out of the way first

is that one enabled?

[west sonnet]

Nevermind, I forgot I turned off gizmos

[shadow field]

yeeeeee

feel that

[grand snow]

That may only work in OnDrawGizmos functions. You can use the package Vertx to draw gizmos from update

Hi I'm trying to make a simple 3d platformer Obstical course project. I'm trying to make a jump button but every time I press the jump button my player continues to go up into the abyss. Is there a condition I'm missing?

        if (canJump)
        {
            if (Input.GetButtonDown("Jump"))
            {
                jumpForce = new Vector2(physics.linearVelocity.x,jumpSpeed);
                physics.AddForce(jumpForce,ForceMode.Impulse);

                canJump = false;
                isJumping = true;
            }
        }
        else
        {
            jumpForce = new Vector2(physics.linearVelocity.x, physics.linearVelocity.y);
        }

[rain grove]

0.5% chance my code runs without errors. 99.5% chance I start debugging before I finish typing.

[wintry quarry]

It's very weird that you're using your current x velocity in the jump force (but that should only lead to horizontal weirdness in and of itself. That else statement seems completely pointless too.
Aside from that, you should show your rigidbody's inspector. Your object is just behaving as if you disabled gravity on it (or in the world)

[still ingot]

It only seems to come back down when I move it around in the air but if I leave it then it continues to go up

[pine imp]

srry wrong chat heh

[wintry quarry]

you should turn your inspector back to normal mode

it's on debug mode

which makes it hard to read

Also you should share the rest of your code

It's almost certainly due to your code

[still ingot]

    public bool OnGround()
    {
        Ray groundRay = new Ray(this.transform.position, -transform.up);

        isGrounded = Physics.Raycast(groundRay, out RaycastHit hit, groundDetectionRayLength, groundLayerMask);

        return isGrounded;
    }

    // Update is called once per frame
    void FixedUpdate()
    {
        //Set your Input variables you made to the Axis they are going to be used for. This will allow for you to get the exact axis the player will be moving on be sure to type the exact name of the axis
        InputHorizontal = Input.GetAxis("Horizontal");
        InputVertical = Input.GetAxis("Vertical");

        Vector3 move = new Vector3(InputHorizontal * speed, physics.linearVelocity.y, InputVertical * speed);

        physics.AddForce(move * speed_Multiplier, ForceMode.Force);

        // Speed limit;
        while ((physics.linearVelocity.magnitude > speed))
        {
            physics.linearVelocity = Vector3.ClampMagnitude(physics.linearVelocity, speed);

            break;
        }

        // ground detection
        OnGround();

        while (isGrounded)
        {
            canJump = true;
            isJumping = false;
            break;
        }

        // Player Jump
        if (canJump)
        {
            if (Input.GetButtonDown("Jump"))
            {
                jumpForce = new Vector2(physics.linearVelocity.x,jumpSpeed);
                physics.AddForce(jumpForce,ForceMode.Impulse);

                canJump = false;
                isJumping = true;
            }
        }
        else
        {
            jumpForce = new Vector2(physics.linearVelocity.x, -gravity * Time.deltaTime);
        }

    }

    private void OnDrawGizmos()
    {
        Gizmos.DrawLine(transform.position, new Vector2(transform.position.x, transform.position.y - groundDetectionRayLength));
    }
}

[wintry quarry]

        // Speed limit;
        while ((physics.linearVelocity.magnitude > speed))
        {
            physics.linearVelocity = Vector3.ClampMagnitude(physics.linearVelocity, speed);

            break;
        }```
This should just be an `if` statement, not a `while`. In fact you don't need either. Clamp only does something if that magnitude is higher anyway. 

`        while (isGrounded)`
this should also be an `if` statement, not a `while`

And finally here's your actual problem:
```cs
        Vector3 move = new Vector3(InputHorizontal * speed, physics.linearVelocity.y, InputVertical * speed);

        physics.AddForce(move * speed_Multiplier, ForceMode.Force);```
Why are you adding the current y velocity to the force here?

you seem to be confusing "adding forces" with "setting the velocity"

I'm fairly certain everything in your script that is calling AddForce you actually meant to set the velocity, based on the way your code is written

You should also stay clear of while for now, you don't seem to understand how it works and it's just cluttering your code. It's also very easy to end up freezing your game using it when you don't understand it.

[still ingot]

Thank you!! It works now!

[still ingot]

I just changed this to be Vector3 move = new Vector3(InputHorizontal * speed, 0f, InputVertical * speed);

[wintry quarry]

you probably want to revisit how you're adding the horizontal velocity when jumping too

and think hard about whether you want to be adding forces or setting the velocity

[elder osprey]

I need to make this action run the Grind method on the instance of the Grinder script that the player is looking at. This is how the grinded action is set up rn, but I don't know how I can use this with a raycast detected object because I would need to do some confusing subscription stuff.

[wintry quarry]

why can't you use it with a raycast detected object?

[elder osprey]

wouldnt it need to reenable or something if the instance of grinder changes?

also what if the instance is null when the player isnt looking at it

[wintry quarry]

You absolutely need to manage it correctly, yes. Subscribing exactly once, unsubscribing when the player looks away, etc.

But it can be done

it's a little tricky if you're not careful

[elder osprey]

Yeah, let me correct my question rq.

[wintry quarry]

Here's the pattern basically:

Grinder currentlyLookingAt = null;

void Update() {
  Grinder lookingAtThisFrame = null;
  // Note if we don't get a raycast hit, or if the thing we hit doesn't have a grinder, lookingAtThisFrame will be null which is expected
  if (Raycast(..., out RaycastHit hit, ...)) {
    lookingAtThisFrame = hit.gameObject.GetComponent<Grinder>();
  }

  // If we're looking at a different thing than last frame. Otherwise, we don't need to change anything
  if (lookingAtThisFrame != currentlyLookingAt) {
    // Unsub the previous grinder, if any
    if (currentlyLookingAt != null) grinded -= currentlyLookingAt.Grind;

    // reassign the variable
    currentlyLookingAt = lookingAtThisFrame;

    // Sub to the new one, if it exists
    if (currentlyLookingAt != null) grinded += currentlyLookingAt.Grind;
  }
}```
@elder osprey

[elder osprey]

Oh, alright. I never totally understood the subscription stuff, so I thought I needed to do it in OnEnable and OnDisable

Thank you

[still ingot]

Are you making rail grinding in a 3D project that sounds awesome??

[elder osprey]

No, I might in the future tho, my current game is a lethal-like and to add to the quota you grind items in one of the grinders located around the map

[still ingot]

OOOOOhh okay still cool stuff

[elder osprey]

I need to do this twice because this logic is happening in my inventory script, when the player presses e they can either Pickup, Grind, or Interact

[still ingot]

I have been working on a 2D rail grind system in unity. I plan to revisit after doing this 3D project I'm more familiar with 2D.

[sour fulcrum]

OnEnable & OnDisable tends to be used for listening because usually monobehaviour activity is similar to clocking in and out of a job, if that makes sense

[elder osprey]

That makes sense

[elder osprey]

Would this be able to work in the Interact InputAction method?

Like up here in the method?

Since I'm already doing the raycast in there

[wintry quarry]

If these things all use the same raycast distance, layers, etc you could probably unify all of it

[elder osprey]

unify?

[wintry quarry]

have one piece of code that handles all the cases

[wintry quarry]

this code is only for when you press a button, so not it's not really the same. In this case it's more straightforward - you just check for the component on the object and run the method directly, no?

Otherwise - you fire the event in the input handling code

and you have the raycast stuff in Update

So it really depends if you're using an event or not

[sour fulcrum]

unsafe reference in here!!

if (hit.collider.GetComponent<ItemPickup>().item != null) will throw if .collder does not have an ItemPickup component.

you should be doing something like

if ((hit.collider.TryGetComponent(out ItemPickup pickup) && pickup.item != null)

[elder osprey]

Does using an event for this case just complicate things? I wanted code to happen once in the Grinder script when something happens, and I think events are the easiest choice for that, no?

[wintry quarry]

yes I think so - it's not clear to me why you were using an event there

but - having the raycast code in Update does make sense often because it's typical to show the user some kind of UI and hide that UI when the action is available

[elder osprey]

I'm using an event because when the player presses e on a grinder, I need code to be ran on the grinder script.

[wintry quarry]

but why does that need an event?

Couldn't you just have:

void Interact(CallbackContext context) {
  if (context.performed) {
    if (currentlyLookingAt != null) currentlyLookingAt.Grind();
  }
}```

(based on the currentlyLookingAt variable in my code above)

If we just keep a reference around to the Grinder we're looking at currently, it's trivial to call the function without an event

I might be mixing up Grind and some other interaction thing here but you get the idea?

Are Grind and Interact two different buttons?

[elder osprey]

With this method, I wouldnt need multiple sets of logic for the Grind and Interact events

[elder osprey]

No, they're both e

[wintry quarry]

yeah exactly

[wintry quarry]

then yeah I would just unify that all under a single interface like IInteractable and put it all in one code section

[elder osprey]

I might have it so interact is its own thing, and the grind logic is handled in the Interact script if the object is a grinder

[elder osprey]

lol, we said the same thing

[tawny mortar]

My objects are moving at 1 meter increments for no reason did I press a shortcut or do smth else by accident

Nvm, I might be possible Not Smart

Hi 👋 would anyone be willing to review a project I have been working on. I'm trying to create a 2D rail grinding mechanic in unity. It's been a while since I last touched it but I plan on working on it again and updating it.

[bleak glacier]

I'm using data persistence for my saving and loading system. I have enums that I want to be able to add to directly using this data persistence system. How do I save all enumerated values?

[grand snow]

On disk it can be stored in it's string form or as it's numerical value (int by default)

[bleak glacier]

So I guess maybe I'm misunderstanding how data persistence works. I

[rich adder]

pretty cool , i'm doing that but in 3D with spline.
do you have a specific concern on it?

[bleak glacier]

Can I not directly save and load to the actual code? I know data persistence saves values and stuff. Like the status of a bool, or the value of an int.

{
    None = 0,
    Ammunition = 1 << 0,
    Finesse = 1 << 1,
    Heavy = 1 << 2, 
}

But if I want to add a new enumerator with the bit shift, can I do that with data persistence? It seems like there must be a way.

[grand snow]

By data persistence do you mean write to some file or do you mean something else?

An enums value IS it's numerical value

[bleak glacier]

So I'm not fully in tune with how the code works. I save to a file, yes

[grand snow]

Save the int and that's it

[rich adder]

most people save it as int

[bleak glacier]

Ok so maybe I'm not explaing myself properly

[grand snow]

You aren't no...

[bleak glacier]

I want to, during runtime, be able to add a new enumerator to WeaponProperty.

[grand snow]

Ohhh no not possible

It's an enum not an enumerator

[rich adder]

wdym a new enumerator ? that means something else , like new "Enumeration" ?

enums are just constants

[grand snow]

If you changed to using int instead of the enum type then there would be no restriction

[bleak glacier]

A new "entry" to the enum. Maybe my source was bad, but that article called entries under an enum enumerators.

Like the Ammunition in my code.

[bleak glacier]

Yes

[grand snow]

Share some code so we can understand what you actually want or need

It's unclear so far

[rich adder]

the design of constant is not to change during runtime

[bleak glacier]

{

[rich adder]

whats the end goal?

explain what you want to do instead of focusing on a specific solution

[sour fulcrum]

These yearn for ScriptableObject’s

[bleak glacier]

So weapons have weapon types, and only certain classes can use certain weapons. A weapon can have multiple weapon types.

I want the user of this program to be able to add additional weapon types to weapons.

[rich adder]

hmm yeah maybe SOs could fit that here

[cosmic dagger]

I would use SO enums for this. Just have a list of the SO enums that belong to the weapon . . .

[sour fulcrum]

Be ideal for when you wanna add extra into to these too

[bleak glacier]

And you instantiate more SOs with custom names or?

[sour fulcrum]

Same SO

one so per type

[bleak glacier]

But I'd need customizable SOs. I need the player to be able to create new types

[cosmic dagger]

Basically, create a SO_WeaponProperty ScriptableObject. Then, create assets in your project folder for all the names (just like you did for your enum) . . .

You can have a list of these SO_WeaponProperty SOs on the weapon if they have multiple types . . .

[bleak glacier]

Cannew assets be created during runtime?

[cosmic dagger]

Yes, you can instantiate or create a new instance of an SO, then name it, but why do you need to create a new WeaponType during runtime? There's no way you could do that using enums (your previous method).

[rough granite]

yeah you cant update / make a enum during runtime

[wintry quarry]

Then an SO is not the solution for you.
Or at least not the complete solution.

What I do in these situations is make two separate types:

• The runtime type, which can be directly created by players
• The SO type, which can create the runtime type on demand but can be edited in the Unity editor

Then at runtime, you use the runtime type basically.

[cosmic dagger]

Do you mean, you want the player to create new types of weapons?

[bleak glacier]

Is there a way to edit the save file, and then add to the enum when the game is reloaded?

[rough granite]

no the enums are built on build

[bleak glacier]

Aight.

[wintry quarry]

You just need to save data in a custom type, it wouldn't be an enum

[bleak glacier]

What do you mean by custom type?

[wintry quarry]

A custom class or struct

[bleak glacier]

So I can do this with structs, but not enums?

[rough granite]

c# is OOP make a class that does what you want

[wintry quarry]

Players cannot change code. They cannot add a type to your enum.

But what you can give them the ability to do is change data

so for example if you had:

public struct Weapon {
  public string Name;
  public int Damage;
}```
You can allow the player to create one of these through UI or whatever

and save it to the save file and do whatever you want

but they can't add an enum value:

public enum WeaponType {
  Sword,
  Katana,
  Dagger,
  // users can't modify your code so they can't add stuff here
}```

[bleak glacier]

Well, they can change the data of strings and ints. I don't know of a way to add a new int though

[wintry quarry]

you don't need to have them add a new int

Just save the data they give you

[rough granite]

this feels like one of those x y problems https://xyproblem.info/

[wintry quarry]

Ultimately the design here is really going to come down to how much customization you want to give the player

it can get very complicated or it could be very simple

On the simple end it's a few bits of data. A name. some damage. Maybe a reference to a sprite or something.

On the complex end you're basically giving them a scripting engine to write custom behavior

[rich adder]

I think they also want something along the lines of "tag" system and only certain classes can use weapons with those tags , but want people to add new tags

[wintry quarry]

And there's a million shades in between those things

In that case you can simply have a string tag or List<string> tags

[elder osprey]

IInteractable?

[wintry quarry]

An example name for such an interface, yes.

[elder osprey]

what do you mean by interface?

[wintry quarry]

I mean a C# interface

https://learn.microsoft.com/en-us/dotnet/csharp/fundamentals/types/interfaces

[elder osprey]

How would I use this in the current context?

[wintry quarry]

you would make all of your scripts that are interactable in this way (looking at them, pressing e) implement the interface, and then you could just have one piece of code that handles all of them (via the interface), instead of a separate piece of code for Grinders, Interactables, and whatever the third things was you said. Items?

It would eliminate your code duplication problem

[bleak glacier]

Yes. This is what I’ve explained. I used enums because you can add flags and then you basically have bools.

And then the classes will also be customizable, ie. the weapon types that their class can use is selected by them

So basically they just select the tags

[wintry quarry]

You can recreate this in software pretty easily. It's essentially just Set operations.

[bleak glacier]

With the presets you’ve seen

[wintry quarry]

HashSet<string> allowedWeaponTags;

// Check if you can use the weapon
bool canEquip = allowedWeaponTags.IsSuperSetOf(weapon.tags);```

[bleak glacier]

I’ll look into it.

[wintry quarry]

You could of course also map each set to an integer value and do bitwise comparisons too. But this limits you to 32 tags for int and 64 for long. It is certainly a lot faster though.

[bleak glacier]

That was what I was doing in the enums

[wintry quarry]

right but it's pretty limiting

[bleak glacier]

Which was the problem

[wintry quarry]

especially with custom tags. And you'd need to keep track of the tag mappings to ints as well

[bleak glacier]

Once again, I find myself greatly indebted to you. I think this is the solution.

[native flame]

Is a kinematic rigidbody for character movement a bad idea if I want a map with lots of physics objects that they shouldn't be able to just walk through?

[rich adder]

kinematic will ignore everything else but not other way around

unless you code it not to hit anything with proper checks

[wintry quarry]

Kinematic CCs are definitely a valid option. Like every character control option they have their advantages and drawbacks.

The biggest weakness of it is that it will be very difficult to allow your player to be pushed around externally by other objects.

If you don't need that, it can be a solid foundation.

[native flame]

From what I've read kinematic will move physics objects around with essentially infinite torque

So if I've got e.g explosive barrels then the player could just walk into them and push them around

[native flame]

Bet

Rn I'm using a dynamic rigidbody and I'm finding it an enormous PITA

[wintry quarry]

I highly recommend checking this out, it's really good out of the box: https://assetstore.unity.com/packages/tools/physics/kinematic-character-controller-99131?srsltid=AfmBOoqAFt2j_q_-5JkxdEQDYS7bHXrFxduZnjdElPuBsgUJ1oVRQdfO

[rich adder]

thats why most controllers are kinematic based

[native flame]

Thanks mate

[rich adder]

even CC is somewhat of a kinematic body

[native flame]

Is this accurate tho?

Because it's a behaviour I wouldn't want

[wintry quarry]

Yep they even call it that in the documentation

[wintry quarry]

yes if you use a kinematic controller you would need to manually implement any "pushback" or "knockback" stuff

oftentimes this is highly situational and worth it

[rich adder]

having more control is def a positive

[native flame]

"pushback" meaning "rigidbodies stop you from moving them around"?

[wintry quarry]

meaning they push you around

[native flame]

Knockback at least seems pretty easy to implement manually

[wintry quarry]

for example if an explosive barrel explodes and you want the player to fly back

or a giant hammer swings and knocks the player off a platform

[native flame]

Makes sense

[wintry quarry]

these won't happen naturally with a kinematic controller without you coding it

(although that asset has some of this stuff out of the box)

[native flame]

But what I'm specifically asking after is if you can stop a kinematic rigidbody from pushing other rigidbodies around?

[wintry quarry]

at that point you're just disabling collisions entirely

[native flame]

What I've read online is that they're a '1 way street' where they push rigidbodies around but can't be pushed themselves

[wintry quarry]

or if those other bodies are also kinematic

[native flame]

Hmmmmm okay

In that case would a non-rigidbody cc be more what I'm looking for?

Since the behaviour I'm looking for is that I've got rigidbodies in the scene that the character can't push around, except when performing certain actions e.g punching

[rich adder]

if the objects are only meant to rect at specific time why not make them kinematic / constraint locked until they are hit "properly"

[native flame]

Y'know that's a good idea

Didn't think about changing that property at runtime

[rich adder]

i often do that so when my char is on a physics object it doesn't wobble

[native flame]

Okay last question: what functional differences are there between a non-rigidbody cc (like Unity's built in cc) and a kinematic rigidbody cc?

[native flame]

Smort

[elder osprey]

Where do you define a interface?

in each script?

[wintry quarry]

you define it once, typically in its own file

[rich adder]

on top of my head / most obvious one, the Character Controller already detects colliders for you while kinematic rb you have to code that in with something like RB.SweepTest or other physics queries

[wind brook]

Does anyone know how I could carry a set of gameobjects over in a scene transition? Ie, I have an object that has to be loaded from one scene to another ‘intact’

[rich adder]

DDOL?

[native flame]

Bet

Thanks for the help gang

[wintry quarry]

You have 3 options:

1. Make them DDOL
2. Use additive scene loading. I.e. they live in scene A and you additively load scene B (and maybe unload scene C, leaving A intact)
3. Let them get destroyed and recreate them from some saved data

[elder osprey]

For some reason adding the IInteractable interface to the Grinder script gives this error

[sour fulcrum]

That’s your hotreloading plugin’s problem

..Which I don’t think is actually discussable on this server, based on how those are made 🤔

[rich adder]

btw there is also this? but never used it myself.. I guess this is mainly for using additive workflow
SceneManager.MoveGameObjectsToScene
SceneManager.MoveGameObjectToScene

[elder osprey]

oh

[wintry quarry]

yeah this would only work in the additive workflow. You need two scenes loaded at once for this.

[wind brook]

Is there a way I can selectively add DDOL to gameobjects that I select while in the first scene (I’m making a fire emblem-style TRPG)? Not the end of the world if I can’t, just feel like it’s cleaner

[wintry quarry]

of coruse

you can do whawtever you like in your code

It won't become DDOL until you call the function on it

So you can just only do that for the ones the player selected.

[wind brook]

Okay that makes sense, but is there a way to then remove it from the ddol list as well?

[wintry quarry]

sure - move it to any other scene with the functions nav mentioned above.

or destroy them manually

[sour fulcrum]

Also might be worth elaborating on the usecase here if you want more specific advice.

Eg. For turn based/“round” games in general, when dealing with units you might not want to reuse the same objects in and out of rounds and instead recreate them at the start of the round using saved data stored elsewhere

[wintry quarry]

Almost exactly what I typed out and deleted earlier^

[restive sentinel]

what are interfaces useful for? I havent come across something yet where i would use it over an abstract class

[sour fulcrum]

Interfaces don’t need to actually do anything, it’s just a promise that it can do something. This allows two very different things to implement an interface that is exclusively what they have in common

[rich adder]

you cant use multiple abstract classes cause of inheretence limitation, but interfaces you can implement as many as you wish

[wintry quarry]

well for one classes can implement multiple interfaces, but derive from only one base class. For two - interfaces can be implemented by structs, which can't derive from anything - including abstract classes - at all.

[restive sentinel]

Thanks, maybe this advice can help with my movement system

[sour fulcrum]

Psycho example but if I myself am an elevator, I don’t need to know what is inside me, I just need to know how much it weighs. Because of that the only thing I need to know could be defined as

interface IWeightable
public int GetWeight();

then anything wanting to be on the elevator (a box, a person etc) just has to implement that interface and single piece of information without being directly related to eachother like

Human : MonoBehaviour, IWeightable

Box : MonoBehaviour, IWeightable

[wintry quarry]

^ the key point is here is that the elevator code doesn't have to know or care about boxes or humans, it can just deal with IWeightable and so you can write simple code for it that just takes each object's weight

[restive sentinel]

So if im understanding this correctly i could make like an IConsumeStamina and put it on a movement state to make it consume whatever it returns?

[sour fulcrum]

then you can use this alongside abstracts, where you might want something like

abstract class EntityBehaviour : MonoBehaviour, IWeightable
abstract int GetWeight();

class Human : EntityBehaviour
override int GetWeight() {}

class Animal : EntityBehaviour
override int GetWeight() {}

[naive plank]

Interfaces : functions needs to be implemented explicitly in the implementing class, abstract classes : not obligatory

[restive sentinel]

Okay i think i understand. Thank you everybody!

[naive plank]

Memory rule I used when doing my courses, implements you could think of something that every one has to do, every one with legs are able to walk. Abstract somethins it can do but dont have to be able to do, there fore youre are not required to explicitly override it in the extending class

[restive sentinel]

Oh i think i see why this could be useful. Maybe for my situation i could make all objects of an interface decrease their stamina consumption by like 20% or something and they will return differently

for like an upgrade

and that would be required due to it having the interface so i dont need to worry about it being null or anything

[eternal needle]

the wording here isn't really accurate. abstract methods dont provide an implementation and have to be overridden too

[eternal needle]

something being null doesn't change here. though yes you could do all of what you described using an interface

[restive sentinel]

Its only required to contain the functions or properties that are not virtual right

[naive plank]

thats right my bad, but all abstract methods dont have to be overriden but interface methods have to if I dont remeber incorectly

an interface just specifies what methods have to be implemented

[sour fulcrum]

Your confusing abstract and virtual

virtual can be overridden
abstract must be overriden

[naive plank]

Think it might be that im mixing it up with Java 🙃

[eternal needle]

im not really sure what you mean here tbh

[naive plank]

Time to take C# course hahaha

[eternal needle]

i did specifically say "and have to be overridden" in the message u replied to btw. u eventually have to implement it otherwise you arent using the class

[restive sentinel]

I’m sorry let me reword this, I meant that functions or properties are not forced to be overridden if they are virtual?

[eternal needle]

and yea you are definitely thinking of java when you said implements that isnt a c# thing either

[naive plank]

I think I assumed the object orientation worked more of less the same, beg u pardon 🙂

[eternal needle]

yes a virtual method provides an implementation, so u dont need to override it

[still ingot]

[rancid lily]

Quick question, how can I define a list of types that extend a certain class?

[iron wind]

List<Action>

[rancid lily]

but I want a list of types

not a list of action objects

(Action is a class I've made here, not system.Action)

[sour fulcrum]

why do you want a list of types

[rancid lily]

Maybe it's a dictionary of types that I want? I want a dictionary that maps a type to an instance of that type

[keen dew]

This sounds like an XY problem

[rancid lily]

got it

[grand snow]

Dictionary.TryGetValue() exists btw

[rancid lily]

idk if there's a way to one line it using try get value?

[grand snow]

kinda but stop caring about such silly things

[rugged beacon]

why do the webrequest has allow scene activation

Presumably AsyncOpertion was originally used only for scene loading so it's a holdover from then

Hello, I tried to code a game with AI. I don't know much about coding; I'm still learning. I encountered an error while writing the FPS view. Actually, it's not really an error, but something I don't want—the player moves while turning left and right. If anyone can help, I can send the code.

[vernal salmon]

I was working on a project again and found that it seems to have stopped working. I have a door button that when you click on it the door opens, the button is a gameobject. It has a collider and it has a rigidbody. The script works when it isn't kinematic but it starts floating away. How can I stop it from floating away

[rough granite]

Is there a reason why the button is physics based?

[wintry quarry]

Attach it to something with a joint.

But yeah I would avoid a physically simulated button at almost any cost.

[vernal salmon]

No its not

[rough granite]

Only time i would understand it is if it's a game like human fall flat and you push the button with the character

[vernal salmon]

I remember it used to work without one

but it only worked with rigidbodies before

[rough granite]

You have a rigidbody on it so it is

[vernal salmon]

And how would I make the button work without rigidbodies

cause it only worked when I gave it a rigidbody

[rough granite]

Animation

[vernal salmon]

no the onmousedown function

not the moving of the button

[wintry quarry]

even then

[vernal salmon]

this is the button

no movement needed

[wintry quarry]

That works when you have a collider, not a Rigidbody

[vernal salmon]

trigger and non-trigger didn't work

am I missing something

[wintry quarry]

you need to explain how your button works

we can't really help without understanding that

[vernal salmon]

you hover your mouse over it you click it triggers an event in another script

that's all

not sure what else I can explain

[wintry quarry]

There's no need for a Rigidbody for any of that

[vernal salmon]

Ik

it just up and stopped working

[rough granite]

Sharing the code would do wonders

[wintry quarry]

Also you can/should use IPointerDownHandler not OnMouseDown

[wintry quarry]

OnMouseDown won't work if you're using the new input system, for example

[vernal salmon]

is that with the old input system

I'm on old

[wintry quarry]

it works for both

[vernal salmon]

and any idea why this isn't working

[wintry quarry]

not really other than some other object is probably blocking it

but OnMouseDown is really not debuggable

other than - it's working or not working

[rough granite]

Honestly couldn't say i would've just gone the route of a raycast

[wintry quarry]

also is this a first person game?

[vernal salmon]

I accidentally doubled all the colliders

of the walls

lol

[wintry quarry]

that'd do it

[vernal salmon]

thansk both of you

next thing I need the onmousedown for I'll use onpointer instead

or raycast

[grand snow]

Event System + IPointerClick is the best

does require a physics raycaster/physics 2d raycaster to work with colliders however

https://docs.unity3d.com/Packages/com.unity.ugui@1.0/api/UnityEngine.EventSystems.IPointerClickHandler.html

[vernal salmon]

lately I've been using IPointer but for this it's a tutorial I made a while back and adding some content to it so I don't want to change but I will mention the IPointerClick when making new stuff

[wintry quarry]

The main benefit of using it is that you get the "is blocked by UI" stuff for free. Basically it interacts properly with other mouse interactions in the game.

[grand snow]

Yea its useful that it does both together

and works with new input system

[coral copper]

i have a very basic question 🙂
obviousely if you want to make a game you will encounter the problem of how to move gameobjects. often times i have been doing it with transform.position += transform.forward * speed * Time.deltaTime; but i know there are also other ways to do it. my question is; what is the best way to do it if you want to have the best performance.

[wintry quarry]

it's really not a performance question

it's a question of how do you want the things to move?

DO you want them to collide with things?

Do you want physical realism?

Do you want them to move on a curve?

Do you want them to move blindly in a direction, or towards a certain waypoint

etc

[coral copper]

ok, well what is the best way of doing if i just want a gameobject moving in a straight line until he runs into a range which is defined by a trigger circle

[hot wadi]

Wait, is this function real? If not then why does it appear in the IDE? There is FindWithTag already

[wintry quarry]

Does your object have a Rigidbody?

[coral copper]

yes

rigid and collition

[wintry quarry]

As it says you need to provide the tag as a parameter

[wintry quarry]

Then you should move it via the Rigidbody

if the body is dynamic (not kinematic), just set its velocity

if the body is kinematic, use MovePosition in FixedUpdate

[sour fulcrum]

are you on unity 6.2

[hot wadi]

Yes, I can provide a string and no error occurs

[hot wadi]

Yeah

[wintry quarry]

Exactly

it's not saying it doesn't exist

it's saying you didn't provide the parameter

[sour fulcrum]

no no their asking no api result

[wintry quarry]

when you provide the required parameter, it's happy

[wintry quarry]

https://docs.unity3d.com/ScriptReference/GameObject.FindWithTag.html It got renamed in 6.0

but the old one is still there. Docs only have the new name

[hot wadi]

So they have 2 copies of the same function now?

[wintry quarry]

yeah

pretty common

[sour fulcrum]

more specifically it seems they dont index the old one on the search

[hot wadi]

Eh, that's odd

[sour fulcrum]

the old page is still there

[wintry quarry]

they're going to deprecate the old one

[naive pawn]

docs do have the old one, it's just not indexed

[coral copper]

so

rb = GetComponent<Rigidbody2D>();
rb.velocity = Vector2.zero;

right?

[sour fulcrum]

which is kinda strange tbh

[naive pawn]

ah whoops

[coral copper]

thanks man 🙂

[naive pawn]

not really, the search results isn't exactly enough space to mark deprecation well imo

sometimes i don't look at docs page and just do search or browse the class page to check spelling (for example)

[sour fulcrum]

i mean yeah but in this situation

search old one -> click page -> says deprecated

search old one -> no result -> gaslit confusion leading to questions here

[naive pawn]

i'd be getting to use deprecated functions in this scenario

and doesn't the ide also report deprecated stuff (and put it low in intellisense) anyways

not recommending deprecated/obsolete things is a good thing, actually

[coral copper]

why do i get forced to use linearVelocity instead of velocity?

[sour fulcrum]

thats what its called now

[polar acorn]

Because it was renamed

[coral copper]

oh, ok. thx 🙂

so its the same thing right?

[polar acorn]

Yes

[primal trench]

how do i make a new transform out of a rotation, position, and scale?

[wintry quarry]

You can't really make a new Transform without creating a whole GameObject. A Transform is a Component on a GameObject.

What are you actually trying to accomplish?

If you just want a place to store those things you can use Matrix4x4 or just Two Vector3s and a Quaternion.

Are you trying to just set the position, rotation, and scale of an object?

[primal trench]

    {
        StartPosition = transform.position;
        StartRotation = transform.rotation;
        StartScale = transform.localScale;
    }```
i did that, but how do i make it so the start position, ect, are only set once, because right now the transforms position and the variable are like, linked amd updated every frame for some reason

[slender nymph]

wdym by "the transforms position and the variable are like, linked amd updated every frame"
those three variables are only set one time in the lifetime of this object unless you have code elsewhere assigning to them

[primal trench]

I'm not. when the transform position changes thevariables change too

[wintry quarry]

They will only be set once right now unless you are updating them in Update

[slender nymph]

prove it

[wintry quarry]

Start only runs one time.

[ivory bobcat]

The three are value types (not reference types). The values will only be copied during Start

[wintry quarry]

Basically you need to show us the rest of your code and explain why you think it's being updated continuously.

[primal trench]

gimme momnt rq

oml im sorry for wasting yalls time i was setting it later in the code

[azure hemlock]

hello, please help me im about to go bald.
OnCollisionEnter is never called: both gameobjects have colliders, both collders are NOT triggers, both have rigidbody kinematic. and one has that script to listen for OnCollisionEnter. both on the same layer too

i do not get why

[naive pawn]

both have rigidbody kinematic
there's your issue

[slender nymph]

https://unity.huh.how/physics-messages

[azure hemlock]

how can i then listen for collision without collidingg?

[naive pawn]

...think about that for a second

[slender nymph]

they can't collide if they cannot collide

[naive pawn]

if they don't collide, why would you get a collision message

perhaps use triggers

[azure hemlock]

i was using trigger, but i need to get contact point, and trigger doesnt provide it

[slender nymph]

there is no contact point if there is no contact though

[azure hemlock]

if something goes thru a wall of the level

[slender nymph]

they are not physically colliding. therefore there is no collision.

[azure hemlock]

how do i get contacct points i need it

[slender nymph]

for what reason

[azure hemlock]

to show particle

[slender nymph]

and do these objects need to physically collide

[azure hemlock]

sometimes yes sometimes no

[slender nymph]

okay so at this point you should provide more actual details so a proper solution can be provided because i don't enjoy playing 20 questions just to get some basic info

[azure hemlock]

for instance, i have a sword, i need it to particle on point of collision

but i do not want any rigidbody physics on it

because its held by character

[wintry quarry]

use a boxcast

or Rigidbody.SweepTest

[azure hemlock]

i tried Physics.ComputePenetration, and collider.ClosestPoint but both are rly bad

is that better?\

[wintry quarry]

yes

[azure hemlock]

which one is better

boxcast or sweep

[wintry quarry]

there is no better

they do different things

look at what they do and decide what you want

[azure hemlock]

yes, in this case

both terrible tried em

problem is they cannot infere the correct direction

[wintry quarry]

yes they can

the normal is contained in the RaycastHit

it has all the info you need

[brave compass]

Physics.ComputePenetration does exactly what it says, I've used it many times with no problems.

But for sword swinging, I would use a sweeptest or raycast. A sword slice contains many points of contact, each with a different normal direction.

[azure hemlock]

yes im doing raycast currently. its not very stable though

especially with non linear shapes of swords

[wintry quarry]

raycast doesn't make much sense to me vs boxcast here

[brave compass]

You have to do multiple raycasts, along the sword, if you want an accurate result. Sweeptest or boxcast don't let you put in an angular velocity.

[wintry quarry]

you would/could do one baxcast each frame during the animation, tracing out the full path over time

which would account for the rotation part too

[brave compass]

There's GIFs in here that explain what I mean
https://mordhau.fandom.com/wiki/Tracers

[brave compass]

Between each frame, the box in the boxcast can't rotate though. It can only move in a straight line. If you don't have enough frames, you won't be able to capture the movement of the sword accurately, especially if it's a very long sword.

[naive pawn]

if you don't have enough frames then you wouldn't be able to render accurately even if you could detect accurately

[wintry quarry]

So what?

This is a simulation. A crude simulation.

The physics engine works in discrete timesteps too

it's not meant to be 100% accurate nor does it need to be 100% accurate

As for frame count you'd use FixedUpdate so the framerate of the game wouldn't affect things anyway.

none of the other mentioned approaches are 100% accurate either

[brave compass]

Just to better illustrate what I mean

[wintry quarry]

yes understood - although you can break that down into arbitrarily as many steps as you desire

nothing limits you to one boxcast per frame

[brave compass]

We don't know how fast their sword is going. With the default 50 FPS fixed tick rate, it doesn't have to go very fast to get these large gaps.

[naive pawn]

you can just rotate the box in frame 2

[wintry quarry]

you can pretty easily make that a configurable parameter

[brave compass]

True, sub ticks is another solution to this. The raycast solution doesn't capture the sweep of the tip accurately.

[naive pawn]

like however the visuals are, rotate the box correspondingly

[brave compass]

The two boxes represents one boxcast. You can only specify one rotation for a boxcast.

It might be better to pick the average rotation between the two frames, if you want to do one boxcast per frame.

[wintry quarry]

this breakdown is also possible (ignore the text, ChatGPT generated this image)

and yes those boxcasts are not accurately rendered - they'd be smaller squares bascially travelling along those paths

[west sonnet]

When creating a system for the player to be able to pick up and discard weapons, if there a typical way to making it? As in, should I instatiate a weapon at the players hand or keep the weapon always there but disabled, and enabled it when it's appropriate

[ivory bobcat]

Your choice.

[sharp junco]

I'm trying to make my first game right now with the first person controller starter asset but there's a hidden code somewhere that's hard locked the far clipping to 500 and I can't find it in the scripts. I can see an override in the nested player unpack prefab but I can't even change the override. any ideas?

[tiny holly]

some one please help me i m stuck with this

when i press a d or s for direction the movement glitches and everything is fast

[naive pawn]

you have both a rigidbody and a character controller that are fighting for control

you can't have both

[tiny holly]

lmao

how to fix it

shall i remove character controller

[naive pawn]

decide which one you want to use and remove the other one

(if you choose character controller you'd also remove the collider, since that's for the rigidbody)

[tiny holly]

I see

and if i use rigidbody then i just have to remove the character controller right

[naive pawn]

and also change any code that might have been using that

[tiny holly]

dayummmmmmmm

it fiexed it

fixed it

tysm means a lot

[sharp junco]

any ideas for the issue I'm running into?

[naive pawn]

which issue?

if you've already posted, link or reply to it

[sharp junco]

just above Ryushio's

[sharp junco]

this one

[naive pawn]

which far clipping are you referring to exactly? on a camera component?

[sharp junco]

yessir. end goal is 4000 far clip and I'll later utilize LOD for performance.

[naive pawn]

what do you mean by "locked" exactly?

[sharp junco]

locked as in I can change the value, but hitting enter reverts the number back to 500 in both the camera component and the override page under the nested player unpack

[naive pawn]

what if you change it to a value closer to what it originally is?

like to 501

[sharp junco]

still reverts to 500, regardless of the value. I checked the scripts in the starter assets folder, nothing in there mentions far clipping either. I'm at a loss with it

[naive pawn]

what about 499?

[sharp junco]

same thing

[naive pawn]

none of the scripts mention farClipPlane?

[slender nymph]

the starter assets use cinemachine, no? so it would be a setting on the vcam not the camera itself

[tiny holly]

@naive pawn Now my player is not jumping only the animation plays.

[naive pawn]

were you perhaps using charactercontroller to do that before

also no need to ping me again

just post your issue

[tiny holly]

okay

so rigidbody cant jump?

[naive pawn]

well there's no jump method, no
you just apply an impulse to make it act as if it were jumping

rigidbodies don't know about jumping, you just tell it what to do in physics terms

you haven't really provided any info to go off of

perhaps show the !code that is meant to make you jump

Am I doing something wrong here with trying to detect the F key in a For loop? The gun is detected so the first For loops works, but nothing happens when I press F so the second loop doesn't work

[tiny holly]

//  void HandleJump()
 {
     isGrounded = Physics.CheckSphere(groundCheck.position, groundCheckRadius, groundLayer);

     if (isGrounded && Input.GetKeyDown(KeyCode.Space))
     {
         rb.velocity = new Vector3(rb.velocity.x, 0f, rb.velocity.z); // reset y before jump
         rb.AddForce(Vector3.up * jumpForce, ForceMode.Impulse);
     }
 }

 void OnDrawGizmosSelected()

     if (groundCheck != null)

[naive pawn]

are you sure the method is even being called? debug at the very top of the method before any conditionals

might be your raycast not hitting anything

also what for loop

[west sonnet]

Sorry, I meant If loop

https://paste.mod.gg/gvphlfqqaikk/0

This is the code ^

The racast is defo hitting it because the Debug.Log is working

[sharp junco]

I checked:

CinemachineVirtualCamera.cs
CinemachineBrain.cs
UniversalAdditionalCameraData.cs
FirstPersonController.cs

CinemachineBrain.cs was the only one with code referencing NearClipPlane and FarClipPlane, but none of that code explicitly sets far clipping to 500 as far as I can see.

 if ((state.BlendHint & CameraState.BlendHintValue.NoLens) == 0)
 {
     Camera cam = OutputCamera;
     if (cam != null)
     {
         cam.nearClipPlane = state.Lens.NearClipPlane;
         cam.farClipPlane = state.Lens.FarClipPlane;
         cam.orthographicSize = state.Lens.OrthographicSize;
         cam.fieldOfView = state.Lens.FieldOfView;
         cam.lensShift = state.Lens.LensShift;
         if (state.Lens.ModeOverride != LensSettings.OverrideModes.None)
             cam.orthographic = state.Lens.Orthographic;
         bool isPhysical = state.Lens.ModeOverride == LensSettings.OverrideModes.None 
             ? cam.usePhysicalProperties : state.Lens.IsPhysicalCamera;
         cam.usePhysicalProperties = isPhysical;
         if (isPhysical && state.Lens.IsPhysicalCamera)
         {
             cam.sensorSize = state.Lens.SensorSize;
             cam.gateFit = state.Lens.GateFit;
             cam.focalLength = Camera.FieldOfViewToFocalLength(state.Lens.FieldOfView, state.Lens.SensorSize.y);```

[naive pawn]

try debugging the values you're checking - isGrounded and the GetKeyDown call

[slender nymph]

show what you are actually changing.

[tiny holly]

ok

[naive pawn]

right, but it's setting the camera values to the cinemachine's own values

[naive pawn]

you would need to modify the cinemachine stuff instead of the camera's values

[slender nymph]

so you remember how i said you need to change it on the vcam not the actual camera?

[sharp junco]

yeah but the vcam doesn'

[slender nymph]

notice how at no point did i say you needed to look into cinemachine's code, just that you need to change the setting on the cinemachine virtual camera
