#

maybe look into using JSON instead though

somber nacelle
#

String.Split also has an overload that accepts a StringSplitOptions parameter to specify you want to trim the entries and remove empty ones

pearl bay
#

i've never used JSON, i feel like that might be going the longer (albeit more sensible and proper) way around this problem

leaden ice
#

json is much simpler and json parsers are even more accessible

waxen perch
#

In terms of getting an input from the player, is there a way to make the script not verify if it was pressed on every frame?

#

I guess you do this by not putting the GetInput in the Update function but where would you put it otherwise?

leaden ice
#

where you'll just get a callback when the button is pressed, for example

waxen perch
#

Is it available in unity 2023.2.20f1?

leaden ice
#

Once you go down deep enough though, that system is powered by checking inputs every frame and simply firing the event whenever something changes

leaden ice
#

there is a learning curve to using the new system if you're used to the old one though, just a warning

waxen perch
leaden ice
#

I'm not saying that, just explaining how it works

#

you should use whatever you think makes sense and makes your life as a developer easier

I'm using Microphone.Start() to capture my microphone into an AudioSource clip so that I can do VOIP.
I'll be transmitting packets n times per second.

My current idea is to play that input AudioSource on a loop w/ volume 0, so that I can determine where the last samples were written when its time to run GetData() on the AudioClip, relative to the audio chunk that I sent last tick.

Am I going about this the right way? Is there a better way? I know Microphone.GetPosition() exists, but it feels weird since it's only the span of 1 second. Where as I have the AudioSource to buffer for several seconds.

#

Any help is appreciated 🙂

heady iris
#

I don't understand -- how would playing an audio clip on loop tell you what samples were last written?

hexed oak
#

well that's the thing, the root object I'm trying to fetch is in another scene. I have a listener for the SceneManager.onSceneLoaded event that searches for that object, and it can't find it--using either LoadScene or LoadSceneAsync. The only way I got it to actually work is by subscribing the .completed event in LoadSceneAsync and then I can find the object.

wary kettle
#

I've never really worked with audio before

#

I'm not sure how else I would do this

heady iris
#

well, sure, but that has nothing to do with how far the microphone has gotten

#

but it feels weird since it's only the span of 1 second

what is "it's" here?

wary kettle
wary kettle
#

I'm hearing myself when I talk

#

This is what I'm using as well. It's just writing microphone data circularly into an AudioSource clip

#

Unfortunately there's not a lot of information online about doing voip from scratch in unity.

#

I'm completely open to other suggestions.

heady iris
#

My understanding is that you want to record the microphone on loop with a modestly-sized buffer

#

You then copy chunks out of that buffer on a regular basis

#

suppose we're recording at 1000 Hz

#

you'd wait until the microphone reaches sample 400, then copy samples 300-400

#

now you wait for it to hit sample 500

fervent juniper
#

Hmm i see, ill send the pic

wary kettle
#

I feel like this would cause some issues in terms of determining how much data to actually send, and ultimately desynchronize us

#

Like if 1500ms of buffered audio needs to be sent, but Microphone.GetPosition is only telling us that we've advanced 500ms (because of the wrap-around)

#

It makes my head hurt just thinking about it

heady iris
#

But yes, you're in trouble if the game hangs for so long that the buffer starts clobbering itself

#

(before you've had a chance to copy the data)

#

In that case, I'd just give up and send only the data I have

#

so if you freeze for 2.5 seconds, you lose the first 1.5 seconds of audio

#

The fun part is dealing with this constant variance on both the sending and receiving ends

#

and then stitching the result into something that sounds tolerable

#

and compressing/decompressing the audio in real-time...

karmic stone
#

Quick tip, it might be useful to create a function that takes 2 vectors, and returns a vector with the x/z position of 1, and the y position of the other. i uh, have wrote this exact thing 500 times before thinking of making a helper function for it.

dense estuary
#

This is how the sampling currently looks:

leaden ice
#

I think the best way to do this is run the poisson algorithm as-is and then scale the points in a second pass. Basically just:

foreach(Vector2 point in points) {
  Vector2 newPoint = point.normalized * point.magnitude * 1.05f;
}```
cosmic rain
#

Yeah, that's probably better. I didn't notice that the points are relative to the actual center of the whole thing.

leaden ice
#

(and do something with those new points of course)

karmic stone
#

Quick question, is the way to get an upwards angle from 1 global point to another global point to just do vector3.cross?

leaden ice
karmic stone
#

I'm doing Quaternion.Lookat( (endpoint - startpoint), (up direction)), and i need to find the up direction, which i dont think? is vector3.up, as they dont have the same y

leaden ice
#

The up direction is whatever you want it to be

#

You are specifying it

#

If it was something that could be calculated from those two points there would be no reason to have it as a parameter

karmic stone
#

yes, but if i have a point at ( 1 5 1), and (2,6,2) how do i get the upwards angle from them?

#

oh, gotcha, then ill reloook at some documentation to figure out what i need.

leaden ice
#

you would use whatever direction you want the top of the object to face

dense estuary
leaden ice
#

the front of it will face from ( 1 5 1) to (2,6,2), but the top will face whatever direction you provide as the up parameter

leaden ice
karmic stone
#

ah, i need the up direction to be perpendicular to the forward direction i get, so i think that is cross product

leaden ice
#

there are infinite perpendicular directions to the forward direction though

#

you can rotate a full 360 degrees

#

You need to pick one

#

In many cases that's the "global up" direction

#

but sometimes it's not

#

it's up to you

karmic stone
#

yeah, i guess i dont understand enough to be taught yet, thank you for trying.

leaden ice
#

having an upside down plane that is facing the forward direction is completely valid. You can choose any roll setting you want.

karmic stone
#

yes, i understand that theres two direction, where im looking, and what way is directly "Above" me. im just getting real confused at why i cant take a forward direction vector and crossproduct it to get a line 90 degree perpendicular to the vector

leaden ice
#

you can

#

it will just be an arbitrary direction

#

also you need TWO direction vectors to take a cross product

#

you can't take a cross product of one vector by itself

#

If you explain the scene here and what orientation you want the obejct to have, it would make this discussion easier

karmic stone
#

I mean its hard to explain because the orientation changes everytime you run the simulation. but ill try one second

leaden ice
#

what kind of simulation is it

#

pictures are probably worth 2,000 words here

karmic stone
#

its the same chopping tree problem ive been working on for awhile now, i figured out a problem with how i was doing it before. the tree is slightly angled in all 3 directions, but you can start chopping it from any direction, and i was able to get the point in the center of the log where you started chopping, as well as the exit point exactly. now im trying to rotate the object im using to cut the tree to get ClosestPoint. give me a sec to enable my debug stuff and grab a screencap

#

oh, i have to create my own coordinate system, duh. just need to find a line for z direction

what are the two points here and which object are we trying to orient?

karmic stone
# leaden ice what are the two points here and which object are we trying to orient?

Think i fixed it myself, but that you for listening to my explaination. the line i have now is between the midpoints of both of the cubes. The upwards direction is legit just one of the top cubes - the bottem cube beneath it, i didnt think it through enough. (i was skipping over the top/bottem cube and getting the midpoint directly, thats why i didnt think of it)

sorry

This is a little cursed but I wanted to check if an object was it's "prefab"/asset by just comparing it's transform.root with itself. any issues come to mind with this?

somber nacelle
#

what would be the purpose of that?

night harness
#

Oh wait nvm im dumb, i'd need to check it's scene right?

night harness
somber nacelle
#

if this is editor only then you can use the PrefabUtility class

night harness
#

Not editor only, I know this isn't ideally what I should be doing 😄

somber nacelle
#

then you should provide the actual purpose of doing this so a proper solution can be suggested
https://xyproblem.info

night harness
#

That's fair, Although I'm not necessarily interested in a specific alternative here and I'm more-so just interested in if there's a viable way to identify them at runtime. What sparked this question is Netcode For GameObject's related but the solution to it might not be specifically NGO related so was looking for help generally. In NGO the workflow tends to mix NetworkObjects being spawned dynamically and existing in the scenes directly and I want to manage my content in a way that can handle both usecases in the same way, so I wanted a way to get the asset from an instance so i can treat them equally

0 vertexes:

#

5 vertexes:

#

figure out how many is appropriate for the extra triangles and away you go

#

if you want to perfectly blocky lines - then use two separate line renderers - the way they are renderered uses triangles and 3d calls - like if you change your render mode to wireframe (from shaded) you'll see

#

on the right one (0 vertices) the triangles "cross over" and go to the same point

image.png image.png
fervent juniper

modern creek
#

i think curved lines looks pretty good with a gradient along the way but .. it's mostly just meant as a quick and dirty line texture.. if you want your own, or want it to have some custom functionality that the default component doesn't have.. then probably just roll your own renderers

#

personally I'd slap a color gradient on it so it's obvious it's reflecting

fervent juniper
#

That's my aim

modern creek
#

ya then easiest is just to make two LRs, one from 0->1 and another from 1->2

#

(in your code)

#

but adding bounces is .. gonna get complicated if you do something where there's multiple bounces

fervent juniper
#

I've added the bounce part

modern creek
#

whereas just adding some vertices and then adding as many positions (bounces) as you need until you run out of range is... probably the Correct solution

#

only for one bounce tho

#

what if it bounces twice

fervent juniper
#

Nah for multiple

#

It wasn't too hard

#

But I had an issue where sometimes the bounce wasn't detected

#

I did open a forum for this but still got no answer

modern creek
#

post? i'll have a look

fervent juniper
#

Yea let me get it

modern creek
#

until these slices of pizza run out anyway 😛

fervent juniper
#

The issue I was having is the raycast sometimes misses the wall

#

Causing it to go right through

modern creek
#

can your direction ever be Vector3.zero? I see you're using a v3 but it looks like it's isometric/2d

fervent juniper
#

Aight here is the link

fervent juniper
#

It's isometric

#

In 3d

modern creek
#

yeah i mean.. it's isometric so you should take your 3d vectors and squash them to 2d so you don't get weird stuff where your normalized vectors have a z (or y - whatever "up" is for you) component .. that'll be hard to debug and see

fervent juniper
#

Ah yea

#

Y is up for me

modern creek
#

is it bouncing like... very many times? it looks like this code is just changing the direction, but if it's going fast enough the bullet will get stuck bouncing every frame inside the obstacle? so i imagine if you're shooting directly at an obstacle it's more likely to "fail" then a glancing shot?

#

you might need to add an "invulnerability" timer to your bullets where they can only bounce once every few frames, depending on how fast they travel when hitting obstacle layer items

#

(probably 0.1 sec or something)

fervent juniper
#

I can show you a video

#

It just misses the collider completely and goes right through it

#

I added an else statement to see if the ray misses and it does whenever it goes through

modern creek
#

tawny elkBOT
fervent juniper
modern creek
#

s'ok leave it

#

just for future

#

and what do you observe? it just fails to call OnCollisionEnter?

#

er

#

OnTriggerEnter

fervent juniper
#

No ontrigger is called

#

what fails is the raycast

#

Ill get the No ray found log whenever it misses

modern creek
#

k so also - update happens after triggers so.. i suspect that your trigger method is "one frame ahead" of where the item will be (on the same tick)

#

OnTriggerEnter happens, you've got the transform.position from the last frame.. should work right.. then it changes direction.. and gets moved by Update().. so like, you're setting lastPosition in both bounce and update

#

(and also moving it in bounce and update)

#

that's fine but .. probably don't do both? since I think you're confusing yourself (it's certainly confusing me)

#

either handle all of the motion in update or none of the motion in update (using physics entirely)

fervent juniper
#

That doesnt make sense tho since Bounce() is really just changing the direction, the issue is with the raycast missing so the code inside the first if statement isnt even called

modern creek
#

if you need to register a bounce then set a temporary flag like "didBounce = true" and then in update, look for that flag and THEN do all the change in direction and move away from the wall stuff

#

but bounce isn't just changing the direction - you're moving it away from the wall, setting the last position, etc

fervent juniper
#

Yea but

#

Its not even called when it misses

#

Thats just there so it doesnt re-trigger

modern creek
#

hm, ok.. well lemme look again.. but at a minimum, it's probably a good idea to only control motion from one place - look over that lifecycle doc and see if that makes sense.. OnTriggerEnter is going to happen before Update

fervent juniper
#

Gotcha, ill probably move that to update

modern creek
#

show me that video you were saying you were gonna paste

fervent juniper
#

Oh yea

#

one sec

modern creek
#

what i'm understanding should happen:

0: <physics>
1: OnTriggerEnter - bullet is in layer 13
2: Bounce() - bullet is moved away from the wall, direction flipped, last position set to X,Y #1
3: Update() - bullet moves, last position set (again) to X, Y #2
fervent juniper
modern creek
#

post the entire bullet monobehaviour (using a paste site) - literally the whole file

#

and followup: is it only the first bullet that fails?

#

oh wait, it's a random one

fervent juniper
#

No not the first

#

just whenever the ray misses

modern creek
#

also, show your console (if you're doing some debug logging)

fervent juniper
#

this is the whole monobehaviour

modern creek
#

show where you Instantiate() these

#

(in another paste)

#

oh also set your maxdistance larger

#

how big are your bullets? (in world units)

#

like probably just use Mathf.Infinity

fervent juniper
modern creek
#

if your bullets happen to be outside of 0.5f (from the center of the bullet) or past the wall, then the raycast will fail

#

why did you use 0.5f? if it's because you used AI, btw.. this is why you don't use AI 🙂

#

(it looks "good" but you need to know what you're doing instead of just doing the equivalent of copying and pasting code)

#

the AI won't know how big your bullets are, or why to use that maxDistance

fervent juniper
# 
for (int i = 0; i < noOfBullets - 1; i++)
        {
            Transform bulletTransform = Instantiate(Bullet, new Vector3(transform.position.x, BulletYAxis, transform.position.z), Quaternion.identity);
            RicoBullet bullet = bulletTransform.GetComponent<RicoBullet>();
            bullet.Initialize(attackDirection, playerController.teamIndex, playerController, damage);
            yield return new WaitForSeconds(0.13f);
        }
modern creek
#

(the - 1 is a bug btw - this is going to shoot one less bullet than you want)

fervent juniper
fervent juniper
modern creek
#

but this is fine - i'd just flatten the attackDirection (just like you are setting the position to a "fake" vector3).. ie:

Vector3 bulletDirection = new(attackDirection.x, 0, attackDirection.z);
bullet.Initialize(bulletDirection, ...)

just so you're sure you don't have random y creep in your bullets - but from the video you don't, so that's not the issue

#

but I suspect the range being so small is the problem.. try just setting it to 100 or not even using it and seeing if that fixes your issue

#

setting the range large isn't that big of a problem - until you have really large levels with thousands of colliders

fervent juniper
#

i can check how big it is in world units but its very small shouldnt be an issue

modern creek
#

just use Mathf.Infinity for the range and see what happens

fervent juniper
modern creek
#

hm, this is gonna require you to debug it a bit more - but another idea is that your physics.raycast call is using transform.position, not lastPosition

#

going back to the lifecycle thing:

#

Sorry, just thinking this through - hard to debug from my side.. but I'm suspicious that your raycast doesn't hit the wall

#

add some debug logging to OnTriggerEnter, give your bullets numbers or something, and track the frames

#

some pseudocode:

night harness
#

has it been confirmed that the bullet has a rigidbody?

modern creek
# 
public class RicoBullet : MonoBehaviour
{
  private int _id;
  public void Initialize(Vector3 initialDirection, int team, PlayerController owner, float damage, int id)
  {
    _id = id;
    direction = initialDirection.normalized;
  }
  private void OnTriggerEnter(Collider other)
  {
    Debug.Log($"Bullet #{_id} hit something. Direction: {direction}");
    ... etc ...
  }
  private void Bounce()
  {
    if (raycast ...  )
    {  
      ...
      Debug.Log($"Bullet #{_id} bounced. New direction: {direction}");
    }
    else
    {
      Debug.Log($"Bullet #{_id} didn't get a raycast. This shouldn't happen. position:{transform.position} direction:{direction}");
    }
  }
}
fervent juniper
modern creek
#

basically you just wanna be able to look at the console and see the details of all the bullets when they bounce

fervent juniper
fervent juniper
modern creek
#

you might be right but it's hard for me to hold this in my head since... you're moving the bullets manually in update but then checking physics in the next frame

fervent juniper
#

how else is ontrigger called then

modern creek
#

rigidbody is different than colliders

fervent juniper
#

you cant detect collisions without a rigidbody right

night harness
#

a lot of people sometimes forget to use a rigidbody, it's always worth checking

#

you can't detect collisions without a rigidbody on one of the two parties

fervent juniper
#

nah yea it has one

night harness
#

so eg. if you had one on the player and not your bullet the player collision would work but a wall wouldn't

fervent juniper
#

Well look this is what i think is happening

#

this is the debug.drawray when the bullet misses the raycast

modern creek
#

again, since you're moving your bullets in update and only checking a raycast of 0.5f and also checking against transform.position instead of lastposition..

#

what's the collider? the brown? or the light

fervent juniper
#

collider for the wall?

modern creek
#

yeah, it's unclear from your screenshot

#

is the bullet hitting the dark brown (and traveling down)?

fervent juniper
#

You cant see the walls collider in that image

#

Ill get a better image

modern creek
#

(add the code i mentioned above, take a video of firing bullets like nonstop - like set noOfBullets = 100, and then put the console visible, and fire at the wall)

#

if you can get a video of that i'll find your bug :p

fervent juniper
#

I think i get the issue

but it seems like the raycast is likely failing if the transform.position is too close to the wall

fervent juniper
#

I think the ray is firiing inside the boundary collider

modern creek
#

probably! collider still will trigger but raycast only works from outside-in

#

which is why you want to use lastposition, not transform.position

fervent juniper
#

I tried using last position as well

modern creek
#

if the bullet has moved more than a bullet-radius' worth since the last tick, the raycast will be pointing out of the inside of the wall

#

well.. the way this is written is going to be a little bit error prone (do you see why..?)

fervent juniper
modern creek
#

you're moving the bullet in two places at two different times in the tick

#

i would simplify that - add a flag to your bullet that you set to true when the physics engine registers a bounce, since you're moving it in update, and .. change direction, move position, whatever you need to, only in that place (in update)

#

like this is complex because you are moving it in update, and then on the next frame, checking for the collider and moving it, and then in the same frame that it collided, moving it again in update

#

plus your raycast is checking from the center of the bullet, which.. depending on how fast it's moving, float rounding, etc.. could be inside the collider in question, so the raycast is gonna be wrong

fervent juniper
#

Is it not possible to fire the ray like down the x vector

modern creek
#

what you probably want to do is just check for a collision, then reflect the bullet from some other ray

#

you'd need at least x and z, but i wouldn't advise that - you're getting into the realm of just rolling your own collider (and doing all that trig yourself)

#

what you probably want to do is keep the start position, cast a ray to the collider, and reflect the direction about THAT ray

#

(not the bullet's current position to the collider)

fervent juniper
modern creek
#

yeah, may as well

#

if your bullet happens to move faster than a radius worth per tick, it'll be inside the wall and you won't get a raycast

#

all you care about is the angle to reflect it anyway

fervent juniper
#

I see, just tried that

#

Its not missing at all

modern creek
#

also as an aside - in your Bounce() method you are (were? in the paste above) setting distanceTraveled = vector3.distance(lastposition, transform.position)...... which is 0 since you just set it

fervent juniper
#

Ye lol cause update is called the frame befoer

modern creek
#

like the light blue line is what you want

#

whether or not you draw the light blue line from the star (the bullet's start location) or the center of the bullet (to the wall) doesn't matter - it'll be the same direction, so you can reflect it and get V2 - which is what you want

#

but if the bullet is close enough to the wall (the bottom bullet) then trying to draw a ray from the bullet's position to the wall will fail

#

your bullets seem small - go tell me their size

#

in world units

fervent juniper
#

How do i calculate it in world units?

modern creek
#

by my math.. they're moving 0.166f or so per frame, and if they're small themselves, like 0.05? 0.10? .. they're gonna whiff on the wall often

#

well here's an easy way for you to test

#

set the speed from 10f to 1f and see if they hit the wall every time

#

then set it to 50f and see if they miss the wall every time

#

in any case, you can fix it just by doing your raycast from the bullet's start position since all you really care about is reflecting the direction about that vector

#

(and doing it from the start position will avoid all this debugging with your bullet being inside of the collider)

fervent juniper
modern creek
#

yeah so, there's your problem

#

since they move 0.166 per frame and the radius is 0.15.. sometimes (probably about 10% of the time?) they're just getting "unlucky" and going more than the radius distance through the wall

#

change the raycast to cast from the bullet origin and your problem will vanish

fervent juniper
#

Doing that right now but its acting a little weird

# 
if (Physics.Raycast(startPos, direction, out hit, 50f))
        {
            direction = Vector3.Reflect(direction, hit.normal);
        }
        else
        {
            Debug.DrawRay(transform.position, direction * 1f, Color.red, 2f);
            Debug.Break();
        }

it bounces back in the same direction and the correct direction

#

I'll show you

#

It also bounces through the wall once as well

modern creek
#

calculate the normal vector from last position directly to the wall

#

make sure the last position is before the bullet hit the wall

#

you are reflecting "about" the hit normal (which is going to bounce it back the way it came)

#

there's two vectors you need - the direction and the normal vector of the surface and your bullet's last position (before! it hit the wall) - reflect using those two parameters

#

not sure what the weird ball bouncing at a strange angle is, but fix one thing first and see if the other is still a problem

#

gotta run though.. hopefully you're on the right track, ask in the channel if not, i'm sure someone will help 🙂 gl

sorry for taking forever to respond but for schoolwork im making a lock that you have to click a certain amount of times for it to unlock and each time you click on the shackle it goes down a bit like time.deltatime

#

I figured out the part that makes the lock go down when you click on it but I'm trying to make it so that the animation for the lock occurs when the shackle is at a certain Y-cord

#

like if y <= 0

If it's the item folder, thats just a item, doesn't have anything it just transfers the sprite image.

#

Sorry my internet is dying

cosmic rain
#

Ok. Let's assume that's unrelated to the issue.

  1. Does the relevant code actually run? Specifically the code where you assign a sprite to an Image component? Did you try logging what sprite is being assigned.
  2. Use the rect tool when inspecting ui. It would make it easier to see it's bounds and avoid confusing other people(like me).

Hello all. My game is typing heavy and being developed for android.

Right now there is a chat window in game (Similar to whatsapp) with the input field at the bottom of the screen.

But the android and ios keyboard open over it and obscure it.

I want to find the height of the keyboard so I can offset my input field up, but I don't know how to to get the height information.

Touchscreenkeyboard.rect returns a zero rect for android.

What are my solutions here?

Hi, I’m a Unity beginner.
I’d like to ask, if a JobWorker keeps failing to get CPU time and a job stays in the job queue for too long without being completed, would the Unity Main thread pull the job back to handle it itself?

        }

I feel like im losing my mind here i cant raycast for the life of me 😭
This raycast is passing right through the tilemap collider and marking all the enemies as visible.
I've tried inverting the layermask with ~(1<<...) but then the enemy is never visible as it hits them.
The reason I'm not just checking if the raycast hits the enemy object is because other enemy objects were blocking the ray and causing it to block visibility, which I don't want.
please help 😬

yup, or if you're looking it up by name as you are there you can use LayerMask.GetMask instead

yep that works! christ every project i do i have problems with raycasting layers

the decision to make int implicitly cast to LayerMask when half the layer APIs return int indices instead is not unity's finest decision lol

Hello everyone, I am creating a graphic settings tab for our game and I'm working on the shadows resolution atm.

I try to modify
QualitySettings.shadowResolution
But it seems that lights override this parameter by default. Is there a way around this issue ? I want to avoid doing something like
light.SetShadowResolutionOverride(false); on every lights HD additional data

#

I can see there is a "HDShadowManager" maybe this is what I should go for ?

#

Basically what I'm trying to achieve is that this should be managed through some global parameter.

I'm using the Unity Splines package, I've got a spline container with the spline layed out and a SplineAnimate component to move an object along it. It's a dinosaur running, when it reaches the end I want to know so I can switch the animation to something else.

What's the best way to get the current position of the object along the spline? Not necessarily the end, as there's a transition time from running to idle

#

it does seem like it is more or less just List<ScriptableObject>, but as it is giving extra functionality to a generic collection like that, why would you say its not worthwhile?

cold parrot
#

I’m not saying that. I’m saying it’s a misguided idea derived from object oriented thinking that solves a problem which shouldn’t exist in the first place. Usually it happens when a project has too many overly specific types of enemies instead of configurations of the same basic actor that express the type.

wheat spruce
#

ah, that makes sense

#

on the topic, can you do much more inside a ScriptableObject other than it simply storing a handful of properties?

steady bobcat
#

a scriptable object is a class instance so it can run code and do whatever but its always exists regardless of scenes

#

e.g. could be a manager with useful functions and fields that you reference in many scenes

wheat spruce
steady bobcat
#

well yea but im just telling you what ELSE is possible

#

may be useful to have a class instance that is created for you and always exists outside of any scenes (inc dontdestroyonload)

wheat spruce
#

I wonder if it could be a good way to keep persisting values. In my game, you collect coins in a level, and later when you return to a hub world, you keep those coins.

so far I store the value in a struct that gets turned into a .json

#

doing it in a SO could act as a nice middle man between the values in game, and the actual saving to a file

thick terrace
#

i think simple structs are usually better for mapping to JSON, you can do it with scriptable objects but there's a lot of drawbacks

wheat spruce
#

I'm still keeping the struct-json, its just that part of my project is starting to get really messy, (ie modifying/reading certain properties is more of a hassle than others)

#

a SO could straighten things out

heady iris
#

Consider a ScriptableObject that contains a struct

heady iris
#

This can cause extremely funny problems

#

So you have to make sure you always hold a reference to it

heady iris
steady bobcat
#

well the managed class will still survive but i guess serialized vars that are assets may be affected

heady iris
#

if Scene A references an asset and Scene B doesn't, it unloads when you load Scene B, and gets reloaded when you go back to Scene A

steady bobcat
#

well yea if it gets gc'd im sure its fine at that point

heady iris
#

I figured this out while studying wtf is actually going on with modified scriptable object assets

steady bobcat
#

but you have informed how shittly they work

Hey, I'm working on monster pathfinding in my platfromer game.
https://pastebin.com/Ug8W13dy I have this code to check which nodes can be achieved by jumping (CanMakeJump)
For some reason it fails to make some jumps that passed CanMakeJump (look at the screenshot)

any ideas what I might be missing?

leaden ice
#

so there will be some error here

eager fulcrum
leaden ice
#

and where is the target

#

I guess if it's the green and yellow spheres in your ss it should be ok on that front

#

as they are apparently the same height off the ground

#

but it might also not be accounting for the corner/lip of that ledge

eager fulcrum
#

circles are the targets, they are usually something like 50.5, 10.5
and start position is the monster.transform.position

#

monster has it's pivot in the center

leaden ice
#

i'm curious if that changes anything

#

because I think your analysis is not considering that the lip kind of sticks out and may block that trajectory

#

(in addition to the formula error)

I am trying to figure out flares for SRP and stumbled upon an issue with Allow offscreen and Screen space occlusion settings do not mix well, flare just shines right through objects if it's center is even slightly offscreen. Maybe I should configure settings more specifically for this, but didn't find much about it on internet, and I just don't buy that there's actually no way to make this works, it's possible in hl2 from Source 2006 but not in unity 6 from 2025? Sorry if this is wrong channel, I just don't really know if flares built with shaders or entirely by regular code.

somber nacelle

no, you cannot index a dictionary with anything but it's key. and dictionaries do not guarantee a specific order anyway so that can't work

best you could do is foreach over the dictionary, but like i said the order is not guaranteed

swift falcon

var vel = rb.velocity.magnitude;
if (vel > velocityThreshold) { rag.TakeCollisionDamage(vel * fallDamageMultiplier * damageMultiplier); }

This seems to fail because the velocity goes below the threshold right at the collision, is there a good way to get it to check right before the collision?

#

Only sometimes it doesnt fail, unreliable (plus, I even lowered the threshold for this)

image.png
somber nacelle
#

store the velocity each frame in Update, since Update happens after collisions are resolved you'll have the previous frame's velocity from before the collision, then use that for your check

swift falcon
#

Thanks though

somber nacelle
#

storing the velocity once per fixedupdate is practically free, you will very likely see no impact at all on performance for that

swift falcon
#

Yeah maybe im underestimating modern computers

karmic stone
#

this bug is so wierd, this line(white line going up) is the EXACT direction im using for up direction on rotating the collider, but it just, doesnt accept it as being the upwards direction? in code: Quaternion.LookRotation(finishedPosition - initialPosition, meshDirection) the forward direction is correct, but not the upwards direction (the cube is a quad, and switching the forwards and up directions DOES give the right rotation, but messes with the collider, might be best to do a plane rather then a quad.) I'm wanting to make the blue line use y rotation, and not affect x/z, then use the up direction to rotate to include both the top cube and bottem cube.

I used Unity Relay for the first time and there is mismatch between the docs ):
im using the com.unity.services.multiplayer package and in their docs
(https://docs.unity.com/ugs/en-us/manual/relay/manual/relay-and-ngo)
and they say to use:
NetworkManager.Singleton.GetComponent<UnityTransport>().SetRelayServerData(new RelayServerData(joinAllocation, "dtls"));

but the constructor cannot resolve it
(if i use the old deprecated package com.unity.services.relay it works)
how do i fix this with the new one?

P.S. I tried to use the other options of the constructor but always got connection errors

somber nacelle

Cannot resolve method:

hi again! i tried to remove all whitespace characters using the techniques seen online. for the sake of gracefully implementations, i don't want to jump over to json in case i come back this project much later and it's just all over the place. unfortunately what i'm trying isn't working?

karmic stone
#

ah, then i need to just do Quaternion rotation, because trying to do it using Quaternion.look just gives me the picture

#

the white line is the actual direction, the green arrow is the direction it gives me

somber nacelle
#

Quaternion.LookRotation will always make the Z axis of the object (blue arrow) point along the desired direction

leaden ice
#

what are you trying to do

#

And which white line?

karmic stone
#

the white line going up/down is the up angle, the one going side to side is the forward, but thats my bad about the misunderstanding

leaden ice
#

sounds like you actually want the forward direction to point down more

somber nacelle
pearl bay
karmic stone
#

im doing basically the cut section of a tree, and the tree is angled both side to side and up/down, so i basically need to cut the tree at every point along the z vector. ill use a Quaternion method to get the angle from the direction

pearl bay
#

Okay, so I'm looking to remove all of the whitespaces from a string I'm reading in C# in Unity. I'm looking for a method to remove the whitespaces since the carriage returns in the string aren't required. I'm currently trying Regex.Replace(lineData[i], @"\s+", ""); and iterating through each character. I'm wanting to find a simple solution to remove these return carriages/new lines specifically.

leaden ice
karmic stone
#

i mean if you go from any side of the tree to the other side, it is a slope. with up being world up/down

pearl bay
#

Sorry for the lack of detail!

karmic stone
#

its like its rotated slightly on all axis's, but done as part of the mesh itself (all world axis's

pearl bay
#

The returns in here, I want to be gone.

summer hazel
pearl bay
#

How do I split by returns though? Also using Regex?

#

Using /r?

summer hazel
pearl bay
#

.Split('/r'); wouldn't suffice?

#

I never thought to split by that, I'm currently only splitting by comma

summer hazel
#

probably \n but I'm not certain, you might be able to use a UTC code or something if that doesn't work

pearl bay
#

Ah, I've never used UTC codes before. Is the correct way to access them also just using a backslash?

summer hazel
#

probably best to check around, just Google "c# return character" and you should get useful results

and sorta - I forget if Split can parse those directly, or if you have to use the UTC classes to convert them

#

I'd try \n first though, that's usually the easiest if you're dealing with normal endlines, but if that doesn't work you'll have to figure out what encoding and character your whitespace is using.

lean sail
#

\r\n, \n, or \r are the new line characters used from different systems

summer hazel
#

also just realized I've been saying UTC rather than UTF, whoops lmfao

steady bobcat
#

yea best to check for \r and \n

lean sail

i've never heard of UTC codes, so i was asking about them

it's messy but i haven't refactored yet, i'm just trying to get it working first

did you look at the docs for trim?

#

leading and trailing

leaden ice
#

yeah to remove them from anywhere you'd use Replace

pearl bay
leaden ice
#

is this still that custom CSV implementation?

lean sail
#

Id also question if you really just wanna remove them, i assume you want to split lines into different elements in an array
Otherwise newlines would just be like

line1
line2

becomes "line1line2"

leaden ice
#

Would have saved time just using a library!

pearl bay
#

It is, but like I said, I want to keep it as in one place and simple as possible. I think the moment I start using JSON or libraries I run the risk of forgetting how things work eventually.

#

(My memory is NOT good)

leaden ice
#

You don't need to know how the library works

lean sail
#

thats honestly a silly reason

leaden ice
#

that's the point of the library

lean sail
#

you're using unity arent you?

leaden ice
pearl bay
#

okay i yield jeez

#

i just wanted to know how to remove the return character, that's all

leaden ice
#

This has these features you will struggle for days with achieving as well:

Compliant with RFC 4180.

Correctly parse new lines, commas, quotation marks inside cell.
Escaped double quotes.
Some encoding types. (default UTF-8)

#

yeah but then you will trip on some other thing next

#

it would just save time to use the lib

pearl bay
#

like i appreciate the help a lot but i just don't think that removing returns should be this difficult?

leaden ice
#

it's not difficult

#

string.Replace

lean sail
pearl bay
#

but replace isn't working

steady bobcat
#

remember it returns a new string

pearl bay
steady bobcat
#

so do myStr = myStr.Replace("\n", "");

lean sail
#

if you're struggling with this, you are a beginner in c#

pearl bay
#

something i haven't done before, i don't really do much data stuff like this

# pearl bay what are you trying to prove?

nothing, its not an insult. if you're insulted by it then 🤷‍♂️ i stated a sentence that a ton of beginners state. This isnt the last issue you're gonna have in relation to making your own csv reader

pearl bay
#

It's just I don't really need a full csv reader, i just need to pass letters thru and then I'm done with it for good.

steady bobcat
#

I did my own csv parsing a bit ago and it can be easy at first but you need to handle " which will often appear to allow for , and \n in a value so it requires more effort to do correctly.

pearl bay

this is actually exactly what i wanted it to do

Next time check the function you want to use to see if it mutates or returns a new value...

I have a question about the unity editor. I have this class, ElementStack, which doesn't inherit from MonoBehaviour since it's just a simple data structure with some methods to handle it properly, my question is, can I show this in the unity inspector in some way?

Hello! Quaternion rotation is being so confusing to me right now. i have a quaternion with a z axis, and a y axis computed from the direction that is the z vector. if you want a rotation thats in 3 space, and you want it to rotate x/z so that the object is on the line contanining low and high point, but keeping the z forward vector (y rotation) facing the same place, how does that work, im learning what works by trial and error but i want to understand what this is.

What properties does it have? Are they all serializable properties?

It's not full of, like, Dictionaries or anything is it?

It has at least one serializable field?

Ah, yeah, those won't show up in the inspector. To serialize an auto-property, you need to add the SerializeField tag to the underlying anonymous filed. Use [field:SerializeField] instead

whole sorrel
naive swallow
# whole sorrel where exactly?

For the two properties in ElementStack. If it has a {get; set;} it needs the field: prefix in order to show up in the inspector

whole sorrel
#

oh these are called auto-properties?

naive swallow
#

Yep. Properties have a get and set

#

and if you don't actually implement them yourself, they're auto-properties

#

and have a hidden backing field. The field: prefix tells the compiler that whatever comes after it should apply to that hidden field, rather than the property itself.

#

So, [field: SerializeField] is saying "Apply the [SerializeField] attribute to the hidden backing field of this auto-property"

whole sorrel
#

I see thanks

#

now the MaxStackSize is working, but the queue still doesn't show up

naive swallow
#

Yeah, I don't think Queues have an editor in the inspector.

night harness
#

Maybe serialize a list that you use to initialise the stack?

whole sorrel
#

Mhhh I think I can mirror it in an array, the issue though is that I cannot set elements this way

#

TBF I just need it for debugging purposes

#

If I need a data structure that allows me to pop the first element and push in the last element and shift the elements each time the first element gets popped I can only use a queue, right?

#

I would have to write custom methods to do that with a Collection.Generics.List, right?

karmic stone

you could do a circular array implementation?

Hello!

#

I have a question

#

I want a character to be playing many "Action" animations

#

If I have many AnimationClips, would it be better to use Animator or hard code it? For example, using Animator would be tedious because we need to set all of the parameters. But for hard code, I'm not sure how to make it work. The problem is, I can't override it

#

I would need to do this

whole sorrel
#

But I could possibly use extension methods that shifts everything left and returns the first element idk

fading cove
#

and call it in code: animator.Play("HandGunIDyingback");

#

I'm not sure this is the best approach, let me know if you have different idea on implementing it!

karmic stone
#

thats the beauty of the animator! you can set up some floats, bools, triggers to trigger transitions between animations

lean sail
karmic stone
#

and you have to add transitions between states.

fading cove
#

It would be better to just reference it in Inspector and call it

fading cove
karmic stone
#

you want to play animations, without the animator. why?

fading cove
#

It's better to use Dictionary/Map

#

And call them in code

karmic stone
#

theres almost no reason to not use the animator for playing animations, you can just pass like your movespeed and direction for playing different animations based on movespeed / direction

sleek umbra
#

Easy save 3, is anyone using?

naive swallow
#

The more animations you have, the more you need to be using the Animator

fading cove
#

Like: SetTriggerShoot, SetTriggerSurhender, SetTriggerParry, etc, etc.

#

20 of them

karmic stone
#

you can do animation events, you can set up auto state transitions based on if the animation finishes, was canceled, or whether the animation did something while playing

#

and many other ways to do animations.

naive swallow
#

Or use a numeric parameter mapped to an enum

#

Or just move your animation changing logic into the animator

whole sorrel
# lean sail hmm there might be a way through an editor script to expose the internal array b...

Haven't tried this yet but I wrote this Extension Method that should work:

    /// <summary>
    /// Removes the first element from the list and returns it. Derived from a queue data structure.
    /// </summary>
    /// <returns>Returns the first element from the list</returns>
    /// <exception cref="System.InvalidOperationException">Thrown when the list is empty.</exception>
    public static T Pop<T>(this List<T> list)
    {
        if (list.Count == 0)
        {
            throw new System.InvalidOperationException("Cannot pop from an empty list.");
        }

        T firstElement = list[0];
        list.RemoveAt(0); // Remove first element
        return firstElement; // Return the removed element
    }
#

And it now shows

Might be nice to wrap that function with a tryget function too

I gotta ask: does using auto-properties rather than manually creating getting and setters add a performance overhead?

no, there is 0 performance difference. auto properties just have the compiler create the backing field instead of you explicitly creating the backing field

How performance intensive is this? Would it be better to clear the queue and re-enque all items rather than replacing the queue?

leaden ice

CurrentElementStack.ToArray();

#

This is also inefficient

#

as that allocates a brand new array as well

whole sorrel

The thing is I need to be able to dequeue items both at the origins and at the middle

leaden ice

If you need this ability to remove things from the middle of the queue, it might be easier to just use a list

whole sorrel

yes but you're already doing an O(n) operation here when you dequeue

two of them in fact

but sure - profile it

how long is this list anyway

At most eight items

leaden ice

then you are overthinking this

#

that's a tiny list

whole sorrel

I'm still unsure but it's going to be averagely four to five items

leaden ice

what you have here is going to be much slower than simply using a list and RemoveAt. I encorage you to profile it though

at most eight end-game

You've presumably got a Rigidbody, but then you're moving your object directly via its Transform.

#

You can't mix and match like that

#

If you want to use a Rigidbody, you need to fully use it for all your movement

#

Moving a Rigidbody directly via its Transform is going to cause issues, as you are seeing.

wanton parrot
#

yeah my player was glitching out like crazy

leaden ice
#

you're fighting against the physics engine

wanton parrot
#

so if i change my movement to a rigidbody, i wouldnt have to edit the jump function anymore?

leaden ice
#

IDK what you mean by "I wouldn't have to edit the jump function anymore"

#

Are you asking "is my jump funciton ok as-is"?

wanton parrot
#

i mean it works as it is. its just when i move left and right in the air, my character experiences an earthquake

#

yeah

leaden ice
#

The answer is, yes it's ok if you wish to use Rigidbody for your cahracter movement

wanton parrot
#

is their a better method? im trying to learn unity as i go

leaden ice
#

A better method than what for what

#

Is there a better method than Rigidbody motion you mean?

wanton parrot
leaden ice
#

That depends entirely on your game and how you want your movement to work.

There isn';t really a "good" or "bad" way to move things without the context of your goals and requirements for your specific game

wanton parrot
#

hmm do you think you could list out the basics so i could do some research on it?

leaden ice
#

Not really, again it depends on what you're trying to achieve

wanton parrot
#

aw i dunno what i want to achieve or what its called. im just trying to make a simple 2d indie game

#

thanks for the help tho

leaden ice
#

Like, if you asked me "what's the best car", there's no way to answer that question without explaining what you want to do with the car. Are you going offroading? Are you driving around town? Are you entering a drag race?

in this case I'm asking something like - what kind of game are you making and how do you want the character movement to work and to feel

wanton parrot

ohhh i see. the character i want is just a person that moves on the xy coordinate system.

That looks like code for walking around in fixed increments on a grid or something

wanton parrot

why not look for a tutorial for a simple 2d platformer

there are thousands of them

i originally used a rigidbody but it was way to chunky

Alongside Color.distance and that gorilla with nine fingers

wdym by "chunky"

wanton parrot
#

i dunno if it the code or my computer, but when i tried moving it, it was hella framy

#

like 10 frames a second

leaden ice
#

that just means you need to turn in interpolation

#

on the Rigidbody

wanton parrot
#

once i used the code given by chat, it was way smoother. thats why i thought that the movement was the right way

leaden ice
#

nah

#

you should have just asked why your movement was so jittery

wanton parrot

okay thanks. ill use interpolation from now on.

Hi folks, I’m prototyping a strategy/tactics game where you play cards, that then play units on a grid-based board, and each have unique ‘ranges’ to their attacks. Unlike chess it’s not a ‘move and take piece’ scenario but instead attacking stationary; with the ranges applying damage to any enemies in range.

I’ve looked at a few videos and resources for grid-based gameplay such as Tarodev’s, but in my head it seems quite daunting to translate these ranges to the grid and give choices based on rotation as seen in the example image.

Does anybody have a good starting point to get the ball rolling on this one? I can find out how to script each individual units with these types of stats but it’s a matter of having the right architecture to make it not so hacky. Appreciate any guidance :]

This is probably a very easy question but it's late and I'm tired (I should go to sleep):

switch (inputVector)
{
    // In order up, left, down, right
    case Vector2 v when v == new Vector2(0.00f, 1.00f):
        _attackModule.SetSelectedElement(ElementType.Air);
        break;
    case Vector2 v when v == new Vector2(-1.00f, 0.00f):
        _attackModule.SetSelectedElement(ElementType.Water);
        break;
    case Vector2 v when v == new Vector2(0.00f, -1.00f):
        _attackModule.SetSelectedElement(ElementType.Earth);
        break;
    case Vector2 v when v == new Vector2(1.00f, 0.00f):
        _attackModule.SetSelectedElement(ElementType.Fire);
        break;
}

I know the input vector only has these four states, is there a way to avoid allocating these four vectors each time to check what the input is?

leaden ice
#

for two you can reuse Vector2.right etc

#

but these are structs, they get stack allocated

whole sorrel
#

Isn't new Vector2 allocating?

leaden ice
#

only on the stack

#

ah that makes sense

night harness
# rose eagle Hi folks, I’m prototyping a strategy/tactics game where you play cards, that the...

In theory your grid would be in some sort of multi dimensional array (if this is 2d then a 2d array) with your unit knowing it's index in this array. From there you can create a function that can convert a position, direction and given distance to a list of tiles.

eg. (very heavy pseudoCode)

enum Direction {Forward, Backward, Left, Right}
Tile tiles[,]
List<Tile> GetTiles(index startingPosition, Direction direction, int range)
    List<Tile> returnList;
    for (i range)
        if (Forward)
            returnList.Add(tiles[startingPosition.x,startingPosition.y + i])
        else if (Backward)
            returnList.Add(tiles[startingPosition.x,startingPosition.y - i])
leaden ice
#

so that range pictured there would be [(0, 1), (0, 2)]

#

you could then write a small routine that would let you swizzle it so it could be rotated arbitrarily as well

#

e.g.:
turning backwards (aka "down") would be negating all the x and y values.
turning right would be swapping all the x and y values
turning left would be both swapping and negating

rose eagle
#

This makes a lot of sense and is pretty much exactly what I’m looking for!! And then I presume that if a unit were to ‘attack’, I could run a for loop detecting enemies with the same array values.

leaden ice
#

yep you just loop over the coordinates in the attack area you ended up with, add them to the attacker's position, and check each of those grid spaces for things to hit

night harness
#

Your Tile class could/should have a reference to whatever is on it that you can access

leaden ice
#

the board data (what's on each space) could be stored in either a Dictionary<Vector2Int, Unit>, or a Unit[, ] (two dimensional array)

night harness
leaden ice
#

I think it depends

#

that will take up more memory, at least initially

#

but if you do need data about the empty tiles, you might need something like that

#

it still also might make sense to keep the tile data and the "who is standing here" data separate

night harness
#

In the context of a board game esque prototype performance surely won't be anywhere close to a tangible problem. Curious on your thoughts on why you might wanna keep that separate though (not replying to correct you or anything just curious on your take)

leaden ice
#

Hoenstly was just keeping it as simple as possible for the example

#

it might make sense for serialization purposes though for example

#

Since the tiles might be part of your game asssets, you wouldn't serialize them when saving the game, but you would want to serialize just the "where are units standing" data

#

it really depends

rose eagle
#

For the record I’m not going toooo crazy (though a tactics card game feels insane enough to me). It’s for a project for a decent deadline, so I’m just looking to get the concept down without hacking through it (hence why I wanted to make sure I was doing this cleanly, which arrays help with tons.) Both approaches make sense in my head and I do appreciate the shove in the right direction :]

Hi ! I'm having some issues with the character movements.
I'm trying to make him protected from falls, so I created an "edge checker". This edge checker checks if it have to protect the player from a possible cliff.
The problem with this is that, at the beginning of a slope, they won't activate since the height isnt enough to be qualified as a "cliff", but when it's high enough and the player is on an edge, it will push it immediately. I was thinking about doing a kind of lerp, like, if it's 50% of a cliff, protect 50% or smth, but I don't think it's the right/best way.

Also, I need to add a physic material to make my character able to fall down walls (else it's stuck in it), but then it makes him slide on slopes...

leaden ice
#

damn you removed the music

quartz pewter
#

yeah xdd

leaden ice
#

one approach that would be simpler from a code perspective but more complex from a level design perspective would be to add invisible walls (colliders) instead

#

to be honest though - I'm not seeing what's problematic here in the video

#

is it not ok for the player to be able to step over the slight lip?

quartz pewter
#

Isnt it bothering if I'd like my character to be able to dash or physic events ? Because then i'll have to disable every collider instead of just the 8

quartz pewter
leaden ice
#

oh - that part

quartz pewter
#

I mean, I'd rather force the player to have a collider at the start than push him like that

#

yeah

leaden ice
#

Just interpolate it or something yeah

quartz pewter
#

I've tried a lerp but it was kinda weird, it was like if the wall tried to make the player bounce x)

steep herald
#

I would too decouple the rendering from the physic and always interpolate the rendering towards the physic, so these artifacts are attenuated. Maybe make the interpolation a function of the velocity so it's not noticeable when higher speeds are reached

quartz pewter
#

kk, I'll try that, thanks !

steep herald

Just to be clear, I mean the physically simulated object and the renderer are 2 distinct objects. Init renderer at physically simulated object's position, and then just constantly move towards it at a rate that's a function of the physically simulated object's velocity and then some constant. This way instantaneous shifts like these just basically vanish and you don't have to sacrifice your physics logic since I think you want this to be as robust as possible

Can somebody explain why I cannot make a Vector3 property drawer? It works with GameObject but not the struct!

# midnight sun I need to override it then so I can add unit conversion. I hate meters default

But all the code will deal in meters 😵‍💫

If I were you I would create my own type and make an implicit conversion operator. Then in the specific cases you need, you can use that:

public struct Vector3Feet {
  const float MetersToFeet = 3.281f;
  const float FeetToMeters = 1f / FeetToMeters;
  private Vector3 data;

  public Vector3Feet(float x, float y, float z) {
    data = new(x, y, z) * FeetToMeters;
  }

  public float x {
    get => data * MetersToFeet;
    set {
       data = value * FeetToMeters;
    }
  }

  // likewise for y and z
}```

I have a toggle button next to it

#

The reason is for the transform component and etc

#

I hate using meters

#

Display as inches serialize as meters

leaden ice
#

I don't think it's possible for built in types that already have property drawers

eager tundra
#

what is the issue with meters though? is it the base 12/10 difference?

midnight sun
#

I like to use inches

#

It's incredibly difficult for me with meters

leaden ice
lean sail
#

you could just treat it as feet or inches if you want

midnight sun
#

Screw it I'm making an overlay lmao

steady bobcat
#

Its metres because its uniform and easy to understand
Im british so I understand the fuckery of using many different methods for speed and distance 😐

#

trying to impose this and having conversions everywhere is probably a bad idea

midnight sun
steady bobcat
#

I presume you can do a custom inspector for transform/vector3 and you can just draw the default and have a HelpBox with the inches info

Hi! can anyone help with unity AR?
I am spawning a prefab on detection of a ref image and the moment it spawn I want to attach the joystick prefab in canvas to it. I'm having a bit difficulty with that.

I am able to successfully spawn the model but no luck with attaching the controller

Hello, is there an easy way to get the way a mesh is facing from a point thats on one of the faces of the mesh? (assuming all vertexs face the same direction on each edge facing world up/down) i could get a face normal by searching the entire vertex array, and taking the cross product of the closest face's edges, but is there any more optimised solution that doesnt involve having a concave collider?

Still on the cutting log problem from 5 days ago, i searched up how to use sdfs in unity but there wasnt really any information on how to use them to create static areas. so i decided to continue to try to use the mesh deformations. i need to rotate the log cutting quad to be in the same direction as the cut mesh is leaning. (tried so many ways but then realised the problem was that i was trying to use my initial hit points as inputs to the many different thing i was trying, which would never give me the results i was trying for

thank you anikki for the info. i really like mesh deformations for its variability, but it seems to come with such a useless performance overhead to do many things with it.

leaden ice
#

Otherwise you'd have to search the mesh for the triangle.

If this is something you'd do a lot you could build up some kind of spatial acceleration structure beforehand to make that fast

never heard of spatial acceleration structure before, but will look into it

Hi! I'm working on a strategy game prototype and am currently coding the basics of my Units. When selected, I want a menu to pop up above their heads with actions as seen in this mockup.

Would it be better to put this in a Canvas or just use a series of SpriteRenderers?

image.png
#

(Also if this is the wrong channel redirect me 🫣. Not sure what best practice would be here)

night harness
#

I'd recommend a canvas in the context of a prototype. You'll run into less resistance and more support online if you run into any trouble

#

def worth asking stuff like this to know but just remember to avoid overcomplicating a prototype. In theory all of this should be bare-bones enough to swap out in the future. especially in this case because regardless of your choice your gonna be dealing with some system that's hiding and showing objects, changing their sprites and moving in the context of the selected unit. that stuff isn't going to change in concept so however you implement it will be pretty easy to move over if you ever want to

this isn't really a code question though

hey so hopefully this is a simple thing to solve but I am currently trying to figure out how to move the weapons in the fps microgame from looking like it is held in the right hand to the left. I have scoured through the code and all I have found are objects in the code and not the code that sets the actual position. Also, are the weapons actually in the hierarchy because I cannot seem to find them.

rigid island
soft shard
# arctic rune hey so hopefully this is a simple thing to solve but I am currently trying to fi...

If they are visible to the camera/game window they absolutely have to exist in the hierarchy, I have not used the micro games so I may not be able to help with specifics, though you can pause the game and use the scene window to select the weapon, which should highlight it in the hierarchy, you can also try searching the hierarchy for most-likely keywords like "weapon" or "gun" or something along those lines, or maybe "player" or "hand" and find it through a parent-child search, its possible they are set to a empty transform that is referenced in some script rather than setting a specific position, but if thats not the case, you could also look in the code for anything that might call Instantiate or .position = or .localPosition =

arctic rune
#

m_WeaponMainLocalPosition = Vector3.Lerp(m_WeaponMainLocalPosition, DefaultWeaponPosition.localPosition, AimingAnimationSpeed * Time.deltaTime); SetFov(Mathf.Lerp(m_PlayerCharacterController.PlayerCamera.fieldOfView, DefaultFov, AimingAnimationSpeed * Time.deltaTime));

#

this is the script that sets the m_WeaponMainLocalPosition that I assume sets its normal position.

soft shard
# arctic rune You would think that, however the weapons don't exist in the hierarchy. I figure...

AFAIK, cameras can only render whats in a scene, so if they do not exist in the hierarchy, that means they also do not exist in the scene, and the camera would have no way of rendering it, if a clone of the object is created, that clone is going to have to exist in a scene - you can test that theory by selecting everything in the hierarchy (except the camera) and disabling it, if the weapon goes away, it is most certainly somewhere in the scene (though possibly poorly named)

soft shard
# arctic rune this is the script that sets the m_WeaponMainLocalPosition that I assume sets it...

You could try adding some Debug.Log statements to figure out the values of the lerp, my guess would be that DefaultWeaponPosition.localPosition actually determine where the weapon gets positioned, but that assumes AimingAnimationSpeed is a value of 1, since Vector3.Lerp is a percentage between "a" and "b" (first 2 params), so maybe you would need to find out how DefaultWeaponPosition sets localPosition, though this is entirely just a guess based on how I understand Lerp to work, and the context it looks like that code is using it in

What should I do if I want a character controller-like controller but with a different collider shape? I don't want to be pushed around with forces. Do I just do raycasts and translate position or what?

cant be pushed around but can push, use sweep to detect walls

This code seems to only sometimes work, and only if the object detected is moving in front of the raycasts and I can't figure out why

It also gives around 20 updates each time it detects something which I dont understand

Hello lads, I've came with a problem and in dire need of help.

What I Need Help With :

  • When a Player is in an area, if the area's position instantly changed, the Player's local position regarding the area still will not.
    This can be seen simplified by illustrating the PLAYER (RED CIRCLE) and the AREA (GREEN SQUARE).
image.png
covert dust
#

and the problem is?

prisma hatch
#

that is the problem, no matter what I do i cant seem to make it work

#

so Im asking for a solution

covert dust
#

well this is a very variable thing in approach, depending on how your game is already structured

prisma hatch
#

I've tried calculating the player's position regarding the previouis position with the new one, but couldnt seem to make it right.

#

what information do you need to be provided to simplify this problem and reach an approach

covert dust
#

is the game divided into chunks/rooms or something?

prisma hatch
#

no it is not

covert dust
#

also let's have 100% clarity - you want the player to stay in the same relative position when an object snaps somewhere else?

prisma hatch
#

yes, as in if the player is standing right infront of the door in the room, after the room's position suddenly snapped to 320 to the right, the player's position inside the room does not change compare the before the snap

#

and thus the player should right infront of the door, unmoved right after the change

covert dust
#

another question: is the player a physics object (for example a rigidbody)?

prisma hatch
#

yes

covert dust
#

this teleports physics objects while avoiding physics jank

prisma hatch
#

thanks

velvet pebble
prisma hatch
#

so should I record the local position first, the teleports the player toward the recorded local position?

velvet pebble
covert dust
#

oh it does? damn 💀

#

then am I mixing up methods? I for sure remember RB having something like that

velvet pebble
#

manually setting Rigidbody.position according to this

prisma hatch
#

what differs from setting Rigidbody.position as opposed to gameobject.transform.position?

wassup, ive been trying to fix this for a bit now but i cant seem to get it work. This is a unity netcode for gamobjects board game where im trying to make movement for the player. this is my movement function [ServerRpc]
private void MoveServerRPC(int way, int input, PlayerStateMachine player)
{
Vector3 pos;

int steps = DiceManager.Instance.diceNumber.Value;
if (way == 0)
{
    pos = new Vector3(player.transform.position.x + steps * input, player.transform.position.y, player.transform.position.z);
}
else
{
    pos = new Vector3(player.transform.position.x, player.transform.position.y, player.transform.position.z + steps * input);
}
player.transform.position = pos;
player.SwitchState(player.spectatingState);

}
but it only works for host which also is synced but client doesnt move at all.

prisma hatch
covert dust
prisma hatch
#

however the player just rotates 90 angle to the left and stuck

prisma hatch
#

oh god could the problem be because 02's property is like this

image.png
covert dust
#

that is probably because of physics jank? maybe try setting the rigid body to kinematic for a moment as you snap it to new place?

prisma hatch
#

that could work, let me try

#

nope, not a physics jank

#

it just does that

covert dust
#

💀

prisma hatch
#

wait acutally

#

i accidentally found the solution

#

I just need to make an empty gameobject, then put both the room and the player in as the child, after ward moves the gameobject

so if I want to make a make a player controller with an elongated collider but I don't want it to be pushed by forces, the only possible way to do that is to code my own movement systems with raycasts and stuff ,yea?

thorn ibex
#

It's the NOT AFFECTED BY FORCES. And you don't necessarily need to

unkempt meadow
thorn ibex
#

Have you tried using Unity's default CharacterController?

#

I'm pretty sure that's not affected by forces

unkempt meadow
#

it can't use anything other than a capsule collider directed in the Y axis

#

I would very much like to use it but it's impossible

thorn ibex
unkempt meadow
#

yes

thorn ibex
#

OK

#

You could either do Rigidbodies

#

And set them to Kinematic

#

Then use RB.MovePosition

#

You could do Character Controllers and manually change the collider

#

Or you could do Raycasts
