@quartz folio would this approach work as well (this is in a different language for testing purposes) ```lua
local lookVector = Vector3.new(1, 0, 0) -- Replace with your actual lookvector

-- Choose any vector that is not parallel to the lookvector
local arbitraryVector = Vector3.new(0, 1, 0)

-- Calculate the perpendicular vector using the cross product
local perpendicularVector = lookVector:Cross(arbitraryVector)

-- Calculate the magnitude of the perpendicular vector
local magnitude = perpendicularVector.Magnitude

print(magnitude)```

quartz folio
#

No

#

What it's describing is simple, I don't understand what you're really struggling with

rich leaf
#

How can i create a serializzer for a type?

agile carbon
#

but i was trying to see if my way was valid by looking at other approaches

quartz folio
#

where is the velocity being used here?

agile carbon
#

is the velocity

quartz folio
#

So why are you getting a vector perpendicular to the velocity

agile carbon
#

rn my forwardVector is in fact the blue vector

#

i need to get the orange one sec

agile carbon
#

okay so the forwardVector is now the orange line, the wheelDirection is now the blueLine and the perpendicularDirection is now the red line

#

So now I am doing the dot between the orange vector and then the direction of the right. does this look good?

#

then i can transfer this to unity

merry stream
#

So I'm making an ability system in unity similar to GAS in Unreal and was wondering if i should make the main "ability system component" that would be on a character calculate their stats every frame (ie calculate what they would be responding to active effects like 25% slowness) or try to do it it in a way that sends events to update the stats only when an effect is added. though i forsee stats not updatinng and annoying edge cases from the second method albeit better performance, what is recommended?

You should have gone over it a bit in middle school and early highschool in 2 dimensions. You have a graph. You move three units right, three units up. Finding the hypotenuse is the same as finding a 2d magnitude here.
A^2 + B^2 = C^2
3^2 + 3^2 = C^2
9 + 9 = C^2
18 = C^2
sqrt(18) = C
C = ~4.24

#

2d and 3d vectors are just offsets from some point

agile carbon
#

i already have the hypotenuse

#

in ur example im trying to find the magnitude of the x axis vector

This is the problem

I haven’t leaned vectors so that’s why idk what I’m doing with dot

#

The paper doesn't really help explain whay you want though

#

I will read above to get clued in

Honestly, I'm really confused. Vertx explained it better than I ever could, and even gave code for it. What part is still causing an issue?

I’ll keep experimenting

what it look like is ur trying to break down the angled vector into x and y component?

I have 4500 GOs and 500 RB2Ds in a scene and see significant performance loss (Physics2DFixedUpdate; specifically the solver). 500 RBs is not even the target as I'm just prototyping right now. Do I immediately have to learn DOTS or how can I rule out newbie mistakes?

Though, you'll need to do proper analysis of the bottlenecks to address the issues properly

past kite
#

was hoping I don't have to start early with optimizing. I could enable/disable RBs depending on whether I need physics for them at the moment.

I'm at the moment not using RBs on them, but that would again drastically increase the number of RBs.

You don't need rbs, for simple gravity logic

it's pretty trivial to calculate and apply the gravity manually rather than using a rb for that

I'm making an FPS game in Unity 2021 LTS and using PHOTON PUN 2 for the networking. The way it works i that once players have joined the room, the host clicks "start" redirecting them all to a unique scene in which they all play. After a set amount of time (I've made it 5 seconds for testing), the game ends, displays a game over text and happy days :). If only

This isn't the case for me and the game is going on FOREVER. I've tried multiple ways to troubleshoot this such as displaying a message in the debug menu when the game is supposed to end, but even then I get no message in the debug menu or an end to the actual game. I have attached my script and a video that shows my problem and really would appreciate your help : )
https://paste.ofcode.org/njKQts7qUbtQHZzz9iCJyb

#

As you can see, the game doesn't end after 5 seconds and the player is just stuck in the scene.

somber nacelle
#

do you have an active Launcher component in the scene

peak karma
#

yes

#

actually, let me check

#

yes i do

somber nacelle
#

show it and the console during play mode after the game should have ended

peak karma
#

ok

somber nacelle
#

also note that you will be starting new instances of your coroutine every single frame for 3 seconds before the game will actually end. though that wouldn't prevent it from ending right now

peak karma
#

It wasn't doing that before...

somber nacelle
#

well the Launcher component is what ends the game. if that component is also in the main menu, then it will do it there too

peak karma
#

ohhhh, so how can i ifx that? make a new scrpt with the code im guessing?

somber nacelle
#

yes

#

and only put that component into scenes where you want that functionality

peak karma
#

ok

cosmic rain
#

Honestly, I suggest you start with a simpler single player game. Follow the unity !learn beginner pathways to get the hang of the basics. Networking is not something a beginner should mess with.

JFC!!!!! I solved my aiming issues

For some damn reason my player prefab had multiple "bulletspawn" objects on them. One directly attached to their Hand_Right_jnt, one on a disabled RPG_weapon on their body, and the actual one attached to their equipped weapon

I had those other ones disabled, but my GameObject.Find() in script was finding the wrong one.

And it was close enough to not trigger any red flags, but far away enough to make aiming go off to pull my hair out

somber nacelle
toxic vault
#

Yeah, but I equip weapons at runtime and attach to the player object. So the bulletspawn objects (children of weapon object) has to be figured out at realtime

#

So the next issue is that I don't make my cursor the exact target (since then my bullets hit the ground). I instead make the target a certain height above ground so it hits zombies in the chest. But this means, my cursor could be at blue and my bullets seem to pass through red. This makes it feel aiming is off.

Ideas on how to deal with this since it's not a true top-down game, but at this slight angle?

The quest 3 generates a mesh but it doesn't apply any UV coordinates to it. I want coords on it. The mesh is supplied to the application at runtime. In a best case scenario, I could have a non-overlapping UV unwrap. Pipe dream. Failing that, even a box projection, or an unwrap/peel that doesn't mind so much about overlapping. Any ideas?

Anyone know how to get the distance to the edge of the screen as a percentage, where 100% is a particular point on the screen and 0% is the edge?

Math. Use Screen.currentResolution to get the resolution and calculate pointer position or if it's in the world then use Camera's world to screen method

mouse position if you need pointer

Screen.height should be used if you support windowed

Here's my code so far:

float distance = Vector3.Distance(d.transform.localPosition, Vector3.zero);
float f = Mathf.InverseLerp(d.transform.localPosition.y, Screen.height, distance);
d.transform.localScale = new Vector3(f, f, f);

I'm trying to get the distance between d and vector 0 at the moment.

Zero is another local position

hey :)
I need help connecting classes in my architecture:
I have a player which can go through different "player states".
he can have a 2D state where he goes only sideways, a 3D state where he walks normally, or for example a ski state where the controls and movement change entirely.
I build an interface and many inheriting classes for each movement state, and a monobehaviour MovementManager that holds a IMoveState _currentState;
he is responsible for calling update and switching between states.
however I am not sure how to link the InputSystem with the different states. so far I just opened many input events on the Interface and just subscribed through the movementManager.
I am sure there is a much better solution to this 🙃
see graph bellow: (InputManager is the wrapper for the input system events)

mental rover
#

if the maps are fundamentally different, it would probably make more sense to let each state handle its movement directly, and turn MovementManager into a state machine that just enables/disables the states

Hey everyone. I have a quick question.

I'm working on a dev console for my game and it's working nicely so far. I'm able to create custom commands, log messages and all that stuff. But, I was thinking that maybe I should also make it so that, whatever logs/warnings/errors get printed in Unity's console to show up in my custom one as well. I imagine that would be nice since when in build you can’t see Unity’s console, obviously.

That works as well, but I'm wondering if it’s a good thing to do. Would accessing Unity’s console slow down the game’s build? (I’m aware that in the final build of the game those logs should be removed so as not to lose performance).

there is no such thing as "a void".

void Update() { }

This is a method called Update. It returns nothing, so the return type is void.

I presume you want a method that returns a bool, since you want it to return true or false...

no it's bool i was wrong

yes, and you said "make a isGrounded() void"

but how to get the height of a mesh collider?

ivory vault

the code you posted is completely invalid; you have placed a big blob of code outside of a method

neon nymph
#

bro what do you mean by penis?

heady iris
#

also, consider another debug message.

i think the problem is that it doesnt detect that the jumpkey is pressed

Do not delete random chunks of code.

!mesh Collider

#

!height of mesh collider

heady iris

or you have the wrong jumpKey

Ok i figured it out it's Collider.bounds.size.y

Debug.Log("grounded"+ grounded);
Debug.Log("ready"+ readyToJump);
}

ivory vault
neon nymph
#

Any opinion for a jump speed

#

a float

ivory vault
neon nymph
#

ok

leaden ice
#

My opinion is you should really clarify what it is. "Jump speed" doesn't seem very meaningful/measurable.
A better idea would be:

  • Max jump height
  • Jump duration
  • Initial jump velocity
neon nymph
#

i'll do 5

leaden ice
#

something along those lines

neon nymph
#

no i want the max jump height

leaden ice
#

Then it should not be called "jump speed"

neon nymph
#

ok

leaden ice
#

and you should make sure the calculations are such that it actually achieves that height as perfectly as possible, else it's not really an effective lever to pull on the design side.

neon nymph
#

ok but i'll try 3.5f now

can someone help me. i am building a 2 - player multiplayer game using the matchmaker service of UGS. Problem i am facing is whenever someone starts matchmaking by generating a ticket and leaves/exits the game before a match is found, the ticket generated by that player is still present in the matchmaker and gets matched to someone else even when the first player has now exited the game.

i am using the following code :

private async void OnApplicationPause(bool pause)
    {
        if (pause == true)
        {
            if (matchticketid != null)
            {
                print("pause Started");
                 await MatchmakerService.Instance.DeleteTicketAsync(matchticketid);
                  
                    print("paused");
            }
        }
        else
            print("not paused");
    }

however only "pause Started" is printed on the android logcat when game is minimised and the actual function of MatchmakerService.Instance.DeleteTicketAsync(matchticketid) and subsequent "paused" is only printed when i reopen the game.

can someone tell me how to solve this issue with the code or suggest me a different approach to my problem??

The x/y/z/w fields on a rotation are not the euler angles

#

they're the four components of a quaternion

#

youl'l need to do something like this

# 
Vector3 eulerAngles = transform.rotation.eulerAngles;
eulerAngles.x = 0;
transform.rotation.eulerAngles = eulerAngles;
rotund saffron
#

i got it ```
transform.rotation = Quaternion.Euler(0f, transform.rotation.eulerAngles.y, transform.rotation.eulerAngles.z);

knotty sun
#

that is not gonna work

heady iris
#

Quaternion.eulerAngles gives you a Vector3 of the euler angles. Since it's a property that returns a value type, you have to store the result in a variable, modify it, and then assign it back.

Does ExecuteInEditMode affect thhe entire class regardless of where it is placed?

#

I'm trying to have a single func execute within the editor but having the entire script run seems like a waste

knotty sun
#

I would not worry about unnecessary overhead in the Editor, Unity creates much, much more than you ever could

leaden ice
#

(executeineditmode only does something when it's placed on the class itself, IIRC)

modern creek
#

I don't do this often but I recall there is a way - how can I persist play-mode changes to editor mode? I'm tweaking some graphics on some VFX and it's a little tedious to copy and paste all the particle effect things back to the editor mode

leaden ice
modern creek
leaden ice
#

and paste in edit time

#

Another cheeky way is to save the thing as a prefab at runtime

modern creek
#

hm... it didn't seem to work for particle systems - is that component actually a "surface" for all the subsystems underneath?

#

it might also be this specific component ("All In 1 Shader") that does something.. fucky with the values

leaden ice
#

Hmm really, interesting?

fickle sable
# leaden ice what are you trying to do

Just trying to toggle a scrim with specific values for testing, doing it manually has wasted far too much time. I just wanna expose a func for it via context menu.

leaden ice

leaden ice
modern creek
#

yeah, it's nbd for AllIn1Shader.. there's a whole bunch of custom editor stuff there.. but I couldn't seem to get the particle system "copy component values" from play mode to editor mode working

leaden ice

#

I'll take a look thanks 👍

modern creek

Hm, tried to repro it in a video and now it works. 🤷 Oh well, thanks PB.

knotty sun
modern creek
#

heh.. I'm just kidding.. most of my stuff runs pretty quickly unless I bork something up pretty bad

#

like that one time i accidentally recursively created a local material from a prefab.... oh man.. that one was bad.

#

I'm so .. timid? when it comes to accidentally fucking up an exit condition on recursion that I have widely implemented an "oops" counter

knotty sun
#

tbh the Editor is pretty easy to bork, I've just discovered an exiting new way of screwing it up with a simple spelling mistake using UI Toolkit, Oh joy

modern creek
#

I just caught up on all the patch notes while considering migrating from 2022.3.17 to 3.22 and .. it's really amazing the number of UIT fixes each release

#

i have empathy if that's your tech of choice 🙂

knotty sun
#

I just hate UI Toolkit less than I hate IMGUI

modern creek
#

really? wow.. i wish I could have a convo with you, since I've used imgui for years and every time I glance at UIT to see if I should go there.. it seems .. bad

#

I do hate very many things about imgui but .. after learning all the stupid stuff you need to do to get particles and/or shaders working.. it's functional enough

knotty sun
#

Seriously, UI Toolkit has a lot to recommend it. It's totally flexible and extendable in code which I like and it's close enough to HTML/CSS to make the learning curve shallow. I've been playing with it since it was introduced back in 2018 and I do all my Editor coding in it now.
For instance I just made this custom inspector and it took, literally, 1 hour to write

Question: If I wanted to make a particle system follow a custom irregular path, would NavMesh be the best solution?

unkempt monolith
#

I'm trying to attach a debugger to a build to debug an issue that only appears in standalone builds but I keep getting this error message in Rider after 20-30 seconds of waiting.

netstat shows that the player isn't even listening to the port that shows up in the attach window, even though I enabled script debugging in Build Settings

image.png
knotty sun
rigid island
#

agree, navmesh is very "stiff"

modern creek
#

Not sure what you mean. Is there a curve component of some sort?

rigid island
#

yeah unity has a Spline tool, you can also move stuff along it easily.

modern creek
#

These are irregular paths but I'd rather not create them programmatically

#

I don't see the component - is it in another package?

knotty sun
#

Sounds ike Spline is your friend

rigid island
modern creek
#

thanks

#

ya this is much more what I wanted.. perfect, thanks

#

shit I wish I knew about this a while ago.. I've been moving particle attractors with tweens in a linear path (programmatically) and it's both a pain in the ass and looks a bit cavemannish

rigid island
#

to be fair I think it was only dropped in 2022?

#

yeah 0.1 came out with unity 2022.1 so whatever that is

modern creek
#

all good.. this solves so many problems I was trying to do the hard way

knotty sun
rigid island
#

it really is an amazing tool, can do all sorts of shit

OK - re splines, do they not .. work in UI space? I couldn't seem to draw a spline until I added a 3d object

rigid island
rigid island
modern creek
#

i'm digging.. it looks like maybe there's something?

But I'm not seeing any overview docs yet

rigid island
#

I think thats for editor scripting

#

iirc yeah you do need a gameobject for the Spline Container

#

which way are you trying to animate on it, it has multiple ways and a component for it too

modern creek
#

Yeah I mean, I have game objects but it looks like these don't work in UI space

#

Basically my problem is that I'd like to have some particle effects move around the border of an image

#

i tried putting the prefab into 3d mode and drawing the spline onto the object but it "missed" 😛

I suppose I could try to make a 3d object that's the size of the UI object but.. my entire app so far is in UI space so I don't know how this'll interact

rigid island
#

the whole spline is in wordspace positions

modern creek
#

ya.. it's fine, I've done worldspace-to-uispace hacky things before but it's .. kinda not fun

#

the bugs are gnarly to figure out

rigid island
#

was thinking that as well, its hacky but might just work :p

#

wonder if thats a feature request

modern creek
#

the way I'm doing my particle effects it should work - they get baked into a UI layer mesh - but it's still likely to have some position bugs/issues.. anyway, I'll see if I can get a proof of concept working and if it is reasonably functional than i'll dive in

#

what, like UI-based splines?

rigid island
#

yeah like a mode you can switch for Screen Space

modern creek
#

i don't know how unity (as a corp) feels about continued support/dev of IMGUI tbh.. it feels like there's some stagnation there

rigid island
#

and working with UGUI

rigid island
modern creek
#

yeah but UIT is something entirely different (that I don't actually have any reasonable skillset in)

#

I've kinda just always done the UGUI thing

rigid island
#

I do all my editor scripts now with UIToolkit just not in-game

modern creek
#

yeah i can't seem to get it to work.. there'd probably be an awful lot of fiddling to translate worldspace/splinespace and UI space

#

lemme clip what i did and maybe if you see any obvious mistakes lemme know

unkempt monolith
#

heh, for in-game UI I use a custom engine-independent solution -- basically UITK minus the visual trees and WYSIWYG (though that stuff is in future plans), but with less bugs and some features we specifically need that are missing in UITK (grid layouts, crisp bitmap fonts, custom widget rendering and some other things)

sadly, not gonna release it to the general public in the near future - the poor set of tooling around it and nearly completely missing docs block that

heady iris
modern creek
#

also when I set "align to world space" at the end, i got console spam with this happy message:

image.png
#

so I suspect that trying to make this work isn't going to be all that much fun/successful

#

Maybe I could use the spline programmatically like a curve? ie, just give me the location at 0<t<1

#

(and then manually move the object myself in UI space)

rigid island
#

and yeah like you said just use the spline for its shape

#

You can sample any point on the spline

modern creek
#

yeah, I think Evaluate(spline, t, position, orientation, direction) is what i want

#

i'll just send my own t in and link it to the spline and then basically treat it like a Curve variable that I can just .. use manually

#

i'm just not sure if I'm gonna need to be scaling it up/down since 3d space is so different than UI space

#

crap, I can't just link a spline in the editor.

[SerializeField] private Spline Spline;

shows this:

image.png
rigid island
#

splines need to exist inside a SplineContainer

#

so you can do SplineContainer.Spline iirc

modern creek
#

cool that worked, thanks

heady iris
#

You can grab SplineContainer.Spline to get the first spline in the container

#

which covers a lot of use-cases

modern creek
#

cool this might work!

#

(i'm just spitting out interpolated float3s along t=0-1)

#

i had to multiply the location by the scale of the 3d object but.. this could work

heady iris
#

oh yeah, a useful thing to know that's...not very obvious at first

#

SplineContainer.Evaluate works in world space

#

Spline.Evaluate gives you a local-space position

#

It makes sense because Spline is not a unity object and has no idea where its SplineContainer is

#

it's just telling you where on the spline you are at a certain t

modern creek
#

cool - well i lucked into the correct use then 🙂

heady iris
modern creek
# 
        [SerializeField] private SplineContainer ParticleSplineContainer;
        private Spline _spline;
// in awake:
            _spline = ParticleSplineContainer.Spline;
            _spline.Evaluate(t, out float3 position, out _, out _);
heady iris
#

you can just use EvaluatePosition if you don't need the other two directions

modern creek
#

cool

heady iris
#

it's faster to use Evaluate than to individually calculate the position, tangent, and up vectors

#

hence why it's there

heady iris
modern creek
#

no, i want local space

heady iris
#

ah, okay

modern creek

i mean, i still might not be using the right hammer for this nail but.. it's a hammer

Hey all. I am trying to deserialize a json file, and get an array of strings from it. But when I try and cast the object to the list I am getting a conversion error.

Dictionary<string, object> assemblyData = JsonConvert.DeserializeObject<Dictionary<string, object>>(assemblyText);

List<object> crntReferences = new List<object>();
if (assemblyData.ContainsKey("references")) {
    crntReferences = (List<object>)assemblyData["references"];
}

with error
InvalidCastException: Specified cast is not valid.
Here is the json

{
    "name": "test",
    "rootNamespace": "",
    "references": [],
    "includePlatforms": [],
    "excludePlatforms": [],
    "allowUnsafeCode": false,

    "autoReferenced": true,
    "defineConstraints": [],
    "versionDefines": [],
    "noEngineReferences": false

#

Was was thinking it was because it is empty, but if I put a value it still throws it. Likewise tried object[] instead of list, but no luck

knotty sun

#

How would I get the values from it then? When I am serializing it back to json I just use a list<string>, and that works.

#

Or are you just talking about the
Dictionary<string, object>
which yes, but is just holding the data

knotty sun
#

I'm talking about your json, that is an object, so you will need a C# class that mirrors it's structure

no, a dictionaty is an object which contains an array of key value pairs

Reflection, Dynamics, many tricks. but in this case it just lazy deserialized to a string, which is fine and all I needed to know.

#

heady iris

Does directly setting the color to Color.clear work?

If not, perhaps your material is opaque/doesn't have alpha clip enabled.

main pawn
#

Right.

modern creek
main pawn
#

meshRenderer[i].materials[0].color = Color.clear; didn't work either

modern creek
#

I have to clean up the code a lot, since there was a lot of fiddling, but basically:

            float3 position = _spline.EvaluatePosition(t) * _cubeScale;
            (GoldParticles.transform as RectTransform).anchoredPosition = new(position.x - XOffset, position.y - YOffset);
rigid island
#

cool glad to know that works without extra fiddle

modern creek
#

i'm still not quite sure why I had to offset the things (with the X and Y offset there) since it .. came out oddly positioned? but it's working well enough that I'll probably use it again

#

after like 30 minutes of trying to figure out why, I gave up and just duct taped it with those offsets :p

rigid island
#

haha yeah I recall having to deal with using the SplineUtility to do some conversion for getting my player to grind on it

heady iris
main pawn
heady iris
#

also, show us the material being used on the renderer

main pawn
#

I can try it on a cube tho

heady iris
#

the inspector for the material, I mean

#

I'm not familiar with that shader.

main pawn
heady iris
#

turn on "Cutout Transparency"

main pawn
heady iris
#

if the material is opaque, then alpha will be ignored unless you're using cutout transparency (which i'd call alpha clip)

main pawn
heady iris
#

alpha clip means each pixel either draws or doesn't draw

#

there's no in-between

#

You need a transparent shader.

#

There might be a separate transparent shader to pick

main pawn
#

It does do transparancy, kinda, but I'm not sure how

heady iris
#

the OmniShade page suggests there's a transparent version

main pawn
#

There is one, yeah. Would that help?

heady iris
#

A transparent shader can blend with whatever is behind it, so lerping the color to Color.clear will make it smoothly disappear

main pawn
#

Ah okay

#

Does seem to work on the material itself, though the tween not so much

#

Would doing this affect only those objects, or every wall?

heady iris
#

When you access the material or materials property of a Renderer, it creates a unique copy of the material if one hasn't been made already

main pawn
heady iris
#

sharedMaterial doesn't do this, so you'll wind up modifying a material that many things use (and modifying your assets, too)

I thought that Unity just hard-transitioned between LODs but it looks like it's a bit smarter - like it gradually adds or removes shadowing from the about-to-be-added-or-removed geometry. Is that correct? If this is done via Unity, Is there a way to control that transition - increase the "LOD shadow overlap" range? The problem is that if you're moving at anything other than a very slow rate of speed the shadow transition happens in a split second, thus negating the benefit of this cool feature.

Quick question,how do I prevent a tilemap from disappearing whenever its layer is changed from default -> literally anything else

heady iris
#

sounds like you've got your camera's culling mask set to only render the Default layer

half cosmos
#

im trying to assign it a separate layer in order to detect collision for specifically that tile map

#

ah ok

heady iris
#

check the inspector for your camera

half cosmos
#

Would that affect it even when outside of play mode?

heady iris
#

Yes, but only if you're looking at the game view

#

If it's vanishing from the scene view, then that could be caused by...

#

the Layers settings up in the top right corner

image.png
half cosmos
#

Yeah imlooking at scene view

#

ok lemme check

#

yup thats exactly the issue tysm

heady iris
#

no prob (:

half cosmos
#

lol

#

ugh now I need to figure out how to actually detect the collision

heady iris
#

a tilemap collider component on the same object as the tilemap will work

#

that'll give you a collider you can bump into, at least

half cosmos
#

Basically, I just want an event to trigger whenever the player sprite walks over a certain tilemap

#

thats basically it

#

player should still be able to walk over it

heady iris
#

it works just like any other 2D collider, so you can respond to collision or trigger messages

half cosmos
#

thing is, I have no idea what to write to acc check for the collision notlikethis

#

Im tryna look it up atm but no luck

heady iris
#

if you want to respond to a collision

half cosmos
#

thanks

#

can I use JSON or XML to store game data instead of scriptable objects? I feel like thats much more manageable in larger projects. If yes are there any tutorials or docs on it?

rigid island
#

I use both though SO +Json

heady iris
half cosmos
heady iris
#

The nice thing about using a scriptable object is that it can directly reference other assets.

misty blade
# rigid island I use both though SO +Json

what about referencing files like sounds (.wav for example) or textures? Let's say I have a sound class with some properties like the audio clip, volume etc. If I wanted to load sounds data from json how could an audio clip be referenced?

lean sail
#

If you need it to reference something else, then SO is definitely easier here

heady iris
lean sail
#

Otherwise you gotta serialize some ID and match that ID to the item when parsed

heady iris
#

you don't reference a .wav

misty blade
heady iris
#

you reference an AudioClip that's imported from a .wav file by the unity editor

#

If you want to be able to point to an arbitrary .wav file on the player's computer at runtime, you need to read the file and turn it into an AudioClip yourself.

#

(This is pretty easy, mind you, but I'm pointing out that it's not at all like just referencing other assets from a ScriptableObject asset)

misty blade
#

could I build my own folder structure for that maybe? Like an external folder with .wav files that json could reference

lean sail
# misty blade it feels great for moddability too

In what sense? You edit a file vs edit fields on the inspector. If your file gets large, that's gonna be worse to search through. If you split up the file into many files, it's the same as using SO except without having access to use editor functionality with it

misty blade
#

I meant for mod support. I don't see how externally you could add your own SO's (but maybe I lack knowladge in this area), but if you store data in you project build folders then you could just easily add more content

lean sail
#

Json does not reference anything, keep that in mind, it is simply text. You may store an ID or folder path in there, but either one of those simply match an existing ID or path that must be looked up. If either ID or path is deleted, you now have an error because it's not automatically referenced

half cosmos
#

@heady iris I tried this but nothinghappens

heady iris
heady iris
#

notably, including adding some log messages to check if the method is running at all

misty blade
heady iris
#

I've set things up so that I could rename all of my settings and existing save data would still work perfectly fine

half cosmos
#

I've tried debugging through that but it hasn't helped either @heady iris

#

I don't think there's anything wrong with what I've used

heady iris
#

tell me the things you've checked, then

half cosmos
#

It's asked if both have a collider 2D, which they do

#

pretty sure they match in the trigger matrix as well

#

Its not inside of another function either

heady iris
#

is at least one of them a trigger collider?

half cosmos
#

yeah

heady iris
#

and does at least one have a Rigidbody2D on it?

half cosmos
#

I have a composite and tilemap collider 2d on the tilemap the player is walking over

#

yeah the player and tilemap both have rigidbody 2d

#

Wait is it an issue if both rigidbody2d are set to static?

heady iris
#

I'd expect so, yes

#

Consider making the player kinematic

half cosmos
#

but its a 2D game I need them to stay on the map

heady iris
#

a kinematic rigidbody isn't pushed around

half cosmos

yes

heady iris
#

but the game object (and all other components) will survive

#

you could destroy defensiveCamera.gameObject to get the entire object

#

also, that's not a cinemachine camera, right?

dense lark
#

no

heady iris
#

if so, that means you are now rendering two cameras simultaneously

dense lark
#

also the camera script is attached to my player

#

so destroying gameobject would destroy my player

It just instantiates a prefab.

gameObject is this.gameObject, which is the object your component is attached to

ah, that'll do (:

#

Okay, so defensiveCameraPrefab is not a Camera

#

It's a GameObject.

#

public GameObject defensiveCameraPrefab;

dense lark
#

my bad

heady iris
#

defensiveCamera is also a GameObject

#

If they were both Camera variables, then you'd need to grab the gameObject property from them to destroy the entire object

#

But they're GameObject variables, so you already have the game object

#

This looks fine to me.

#

Did you get an error in the console?

dense lark
#

it just doesn't delete the camera

heady iris
#

does a new camera spawn every time you hit F?

dense lark
#

yes

heady iris
#

or is it every second time?

dense lark
#

or no

#

every second time

#

the defense bool gets switched each time F is pressed

heady iris
#

show me a screenshot of your entire console

#

making sure you don't have errors hidden

dense lark
#

one second

heady iris
#

okay, good, no errors

image.png
#

these buttons would be colored darker if you had info/warning/error messages hidden

dense lark
#

i see

heady iris
# dense lark

Perhaps you have more than one thing spawning defense cameras? Try logging at the very start of OnDefend.

#

although, if you had duplicate defend menus, each one would still be cleaning up after itself

dense lark
#

what do i log?

heady iris
# 
Debug.Log("Defend called", this);
#

that'd let you click on the log entry to see who logged it

#

But if only one camera is appearing at a time, then I doubt you have duplicates.

dense lark
#

yk what

heady iris
#

Does anything else set the defend field on DefendMenu?

dense lark
#

is it possible to just create an instance of the defense camera in my scene, have it disabled, and then just turn it on/off when I press F?

heady iris
#

I noticed you have a UI button that does it

#

I wonder if something else is interfering

dense lark
heady iris
# 
[SerializeField] Camera defenseCamera;
#

(this way, it's not public, so other classes can't mess with it)

dense lark
#

okay

heady iris
#

and since it's a Camera, not a GameObject, you can just enable / disable the camera

#

instead of having to deactivate the game object or use GetComponent on it

dense lark
#

and how would i go about turning it on/off?

#

is there a method that lets me do that

heady iris
#

many things have an enabled property

dense lark
#

so camera.enabled = false should do the job im assuming

heady iris
#

Correct.

dense lark
#

tysm

#

works now

heady iris
#

The only avenue I see is for something to have been messing with defend, since it's public

dense lark

idk, i was probably stuck trying things for an hour

#

Oddly specific but I cant really find much. I'm trying to find the corresponding sharedmesh that a raycast hit. This will be running on android (specifically quest 2) so I want to make this as performant as possible. Is there any better way of doing this?

                MeshFilter filter = hitInfo.collider.GetComponent<MeshFilter>();
                MeshRenderer renderer = hitInfo.collider.GetComponent<MeshRenderer>();

                if (renderer != null && filter != null)
                {
                    for (int i = 0; i < filter.sharedMesh.subMeshCount; i++)
                    {
                        int[] indicies = filter.sharedMesh.GetIndices(i);
                        
                        for (int x = 0; x < indicies.Length; x++)
                        {
                            if (x == hitInfo.triangleIndex)
                            {
                                Debug.Log(renderer.sharedMaterials[i]);
                            }
                        }
                    }
                }
#

It just feels a wee bit off

#

Not very experienced with any mesh related things so I've probably gone down some unnecessarily unperformant route

#

In-fact this doesn't even work annoyingly.. any other suggestions?

#

Thought it did until I threw more materials into the mix

delicate granite
#

hey, i made (followed a youtube tutorial) a car controller script thing. it works until i try making the wheels visuals work.
the part of the script used is

void FixedUpdate{
// the rest of the script that makes stuff work
 UpdateWheel(frontLeft, frontLeftTrans);
        UpdateWheel(frontRight, frontRightTrans);
       UpdateWheel(backLeft, backLeftTrans);
        UpdateWheel(backRight, backRightTrans);

    }

void UpdateWheel(WheelCollider col, Transform trans) {
        Vector3 pos;
        Quaternion rot;
        col.GetWorldPose(out pos, out rot);
        trans.position = pos;
        trans.rotation = rot;
    }

the car flips horribly when the wheel turning part is added. does anyone know why it does this?

thanks!

half cosmos
#

what's the equivalent of using "yield return new WaitForSeconds" in a public void?

#

I want to add a bit of a delay in the function

delicate granite
#

starting a coroutine and then making it go back i think

#

idk im not the best at this

spring creek
quaint rock
#

is none

spring creek
#

Yielding to the main thread requires an asyncrounous function, which a coroutine is

#

The IEnumerator it returns is HOW it can yield (it enumerates the state of the coroutine)

heady iris
#

I wouldn't say you're "yielding to the main thread"

#

yield statements in an IEnumerator-returning method cause the enumerator to pause until it's resumed by a MoveNext() call

quaint rock
#

yeah coroutines have nothing to do with multithreading

heady iris
#

You can't do this in a function that's not being used as a coroutine.

quaint rock
#

its jsut yielding till a future frame

heady iris
#

Waiting for one second in an Update method would freeze the game for one second.

heady iris
spring creek
#

Yeah sorry that was not clear. I know it has nothing to do with multithreading. I just meant it yields, allowing other code to run. Which is this case is stuff on the main thread since coroutines are not multi-threading

heady iris
#

also, hitInfo.triangleIndex is a triangle, not a vertex

#

oooh, no, GetIndices gives you an array of vertex indices used in triangles

#

so that's reasonable

#

but your code isn't actually checking against those indices right now

for (int x = 0; x < indicies.Length; x++)
{
    if (indices[x] == hitInfo.triangleIndex)
    {
        Debug.Log(renderer.sharedMaterials[i]);
    }
}

it ought to look like that

#

...well, no, that's still wrong

#

hitInfo.triangleIndex isn't a vertex index; it's a triangle index

dusk apex
heady iris
#

public is a member access modifier, which controls who is allowed to see the method

#

and void is the return type of the method

#

the method returns nothing, so the return type is void

heady iris
#

i.e. if submesh 0 has triangles 0 through n, submesh 1 has triangles n+1 through n+m, etc.

Here is a snippet of the code:

I am struggling with this basic problem im kinda new

full canopy
#

I'm finishing up the movement system for my vr game and one of the last things I want to add is the ability to climb/vault over objects. I don't want the player to be able to scale any wall, but I do want the player to be able to climb up any object if they can grab the upper outer edge of it. The player's hand colliders are triggers for other reasons.
Basically, I want them to be able to climb if they grab anywhere on the green, and not inside the object or anywhere in red.
I have tried several methods and they either involve tediously adding thin horizontal capsule colliders to the top edge of each object in the scene (even worse on curved objects), or would be extremely unreliable in use. I don't know where to go from here so I would appreciate any advice i can get

diagram.png
heady iris
full canopy
#

i thought of that but don't know how to account for only finding the edges

heady iris
#

I was prototyping a parkour game a few months ago (didn't get very far into it)

#

oh hey, I can just look at the code i wrote for that

full canopy
#

somehow i've not had that happen to me once while working on this lol

heady iris
#

this is...not very enlightening, is it

image.png
full canopy
#

nope lmao

heady iris
#

This was for vaulting up onto a surface

#

so it's actually more complex than what you need anyway

full canopy
#

well no id need the ability to do both

#

climbing over and climbing onto

heady iris
#

I'd shoot a single ray down from the player's hand to find the surface

#

Next, I would shoot many rays downwards along a line between the player's head and the player's hand

#

the rays would have a length a bit longer than the distance from the hand to the surface

#

If too many of those rays hit a surface, then the player's hand isn't on an edge

full canopy
#

ah that makes sense

heady iris
#

note that this doesn't do anything if the point is inside the collider

#

hmm, although i'm not sure exactly how that'd go

heady iris
# heady iris this is...not very enlightening, is it

This system fired a bunch of raycasts forwards. If one hit the surface and the next one didn't, then the edge must be between those two rays.

Then it shot rays inwards from your left and right shoulders to find places to put your left and right hands

full canopy
#

well i dont have to worry about moving the hands given this is vr

heady iris
full canopy
#

i think ive got the idea enough to get something similar working, thank you!

heady iris
#

Firing many rays did work pretty well for finding an edge

thats pretty smooth

Where do you apply enemyPos to the position of the ui?

gentle glen

That's where you've assigned it. Where do you apply it to the ui transform?

gentle glen

#

Where in code?

gentle glen
#

lockOnGraphic.position = enemyPos;

#

Despite usiung a test transform, the lockOnGraphic still appears in the same bottom left area

dusk apex
#

Alright, so maybe you ought to call DefSetup after updating the position?

gentle glen
#

It's meant to really be called in Update()

dusk apex

Else the value isn't updated to the current enemy position

gentle glen
#

oohhhh i see what you meant

gentle glen
# dusk apex

I applied this to my script, and it still didn't work

#

I tried using a different image and it still returned the same behavior

dusk apex
#

Can you show the updated script?

gentle glen
#

I'm only gonna show void Update for now

# 
void Update()
    {
        tgtI = bbRikusen.targetIndex;
        if(tgtList.Targets[tgtI].tag.Equals("GiodEBody") == true)
        {
            unitMN.SetText("GD-03");
            apMeter.maxValue = tgtList.Targets[tgtI].GetComponent<GiodEAPH>().MAP;
            apMeter.value = tgtList.Targets[tgtI].GetComponent<GiodEAPH>().CAP;
        }

        if(tgtList.Targets[tgtI].tag.Equals("EnemyTurret") == true)
        {
            unitMN.SetText("TURRET");
            apMeter.maxValue = tgtList.Targets[tgtI].GetComponent<EnemyTurretAPH>().CAP;
            apMeter.value = tgtList.Targets[tgtI].GetComponent<EnemyTurretAPH>().AP;
        }
        lockOnGraphicGO.SetActive(LockedOn);
        tgtListTransform.RemoveAll(s => s == null);
        enemyPos = Camera.main.WorldToScreenPoint(tgtListTransform[tgtI].transform.position);
        DefSetup();
    }

    public void DefSetup()
    {
        tgtI = bbRikusen.targetIndex;
        lockOnGraphic.position = enemyPos;
        tgtI = bbRikusen.targetIndex;
        LockedOn = bbRikusen.LockAtTarget;
    }

Try placing this before the DefSetup linecs Debug.Log($"{tgtListTransform[tgtI].name} was targeted at world position {tgtListTransform[tgtI].transform.position} and at the screen position {Camera.main.WorldToScreenPoint(tgtListTransform[tgtI].transform.position)}", this);Edited typo

Alright

#

Gonna send the debugs after playtesting

#

God I wish people would use the debugger

Turret was targeted at world position (376.00, 50.84, 70.60) and at the screen position (960.00, 540.00, 211.79), this

It seems very weird to set something's world position to a screen position

#

Also worth noting that UI space is not necessarily screen space. If this uses UGUI then you would need to account for UI scaling

I've got to go, good luck

is it ok if you can help me
i tried help from other people
and it seems like i can't get it through
no matter what i do

#

oh wait
looks like i found a solution
it really has to be a separate GO canvas with world space

right now I'm looking to render the vfx for a player when the sword is swung; is it more common for a whole gameobject to be created with a mesh renderer? or is it just fine to use Graphics.RenderMesh?

Because when I think about it I still find myself changing the localposition of the gameobject and raycasting, and not needing the functionality of the gameobject.

#

Is there a better way to do this than call graphics rendermesh every frame? Or is that how the mesh renderer itself does it

#

In the most basic case yes a meshrenderer would result in a draw call similar to Graphics.RenderMesh

#

But if your vfx is a mesh, why not just enable/disable the GameObject? I feel like manually drawing the mesh adds unnecessary complexity to this.

Frankly I don't like having too much referencing to other gameobjects in the scene, so I keep as much behaviour of the script to one gameobject if possible
