foreach (GameObject position in rampEMPTY)
{
if (Vector3.Distance(position.transform.position, transform.position) <= chunkLength)
{
Instantiate(ramp, position.transform);
}
}

ive been trying to think of the right way to do these things, and i finally did it 😄

[runic nimbus]

Bump on this question

Another example from another game,

My current results

                Vector3 handsDirection = hand2.position - hand1.position;
                transform.rotation = Quaternion.LookRotation(handsDirection );```

See how it flips around after going above 90 degrees?

I know jack about quaternions so I dont know how to work with this

[lunar python]

how to you apply changes from Input to Finite State Machine. Do you have to check whether a state can perform some capabilities before executing it. Like when player is swimming, they can't jump

[runic nimbus]

A "state machine" is just a function of code that allows for other paths during certain states.
A state machine can be a bunch of if statements that take your input and allow certain actions during certain states.
i.e. in the standing state, a player can press C to crouch or shift to run. A crouching state would allow for C to uncrouch, but not run

[spring creek]

New input or old input?
It could change the way you approach this

[runic nimbus]

if(CharacterState == State.Standing) {
  if(Input.PressedC) { CharacterState = State.Crouching; }
  if(Input.HoldingShift) { CharacterState = State.Running; }
}
else if(CharacterState == State.Crouching) {
  if(Input.PressedC) { CharacterState = State.Standing; }
}
else if(CharacterState == State.Proning) {
  if(Input.PressedC) { CharacterState = State.Crouching; }
}```
@lunar python An example of a state machine that uses input to handle a character's pose

[lunar python]

what if I want the player to do both jumping and moving at the same time?

[spring creek]

I assume that first if should set state to crouching?

[runic nimbus]

Oh yes my bad

[spring creek]

Eh, it's just an example. All good 😸

It gets the point accross

[lunar python]

platformer usually allow player to do a bit of air hovering while at the peak of jump

[runic nimbus]

Well you could do something like this

if(CharacterState == State.Standing) {
  if(Input.PressedC) { CharacterState = State.Crouching; }
  if(Input.HoldingShift) { CharacterState = State.Running; }
  if(Input.PressedSpace) { Jump(); }
}
else if(CharacterState == State.Crouching) {
  if(Input.PressedC) { CharacterState = State.Standing; }
}
else if(CharacterState == State.Proning) {
  if(Input.PressedC) { CharacterState = State.Crouching; }
}```

Jumping isn't exactly a state, and can be separate

But this way, you could only jump when standing

[lunar python]

https://paste.ofcode.org/DXYq3VKMkBxninjDrzXryJ

what if I do something like this

should this be possible?

[runic nimbus]

What does this accomplish?

Gives player the ability to do certain actions, cool

[lunar python]

I seperate states by Unique conditions that allows player to do certain actions

Trying to add doors to my dungeon generator but for some reason the script I made is doing literally nothing. ```cs
public class DoorSpawner : MonoBehaviour
{
[SerializeField] private GameObject doorPrefab;

private void OnTriggerEnter(Collider other)
{
    // Check if the colliding object is another DoorPoint
    if (other.CompareTag("Door"))
    {
        // Destroy the colliding DoorPoint and its associated doorFiller objects
        Destroy(other.gameObject);
        Destroy(other.transform.parent.gameObject);

        // Instantiate a new Door prefab at the position of this DoorPoint
        InstantiateDoor();
    }
}

private void InstantiateDoor()
{
    // Instantiate the Door prefab at the position and rotation of this DoorPoint
    GameObject door = Instantiate(doorPrefab, transform.position, transform.rotation);
}

}``` I'm trying to make it such that when two doorpoints are colliding (Meaning that two rooms with doors at that spot are adjacent), they will each be destroyed along with the wall filler and replaced with a door. At the moment nothing happens when they collide and I am not sure why

Attached a couple pictures showing how the doorPoint is setup, and what one and the filler look like in the scene

In the hierarchy doorPoints are children of the fillers

[latent latch]

do you have the requirements to make OnTriggerEnter to work

[high summit]

what exactly are the requirements

[latent latch]

You're missing one component there for it

[high summit]

Wait what am I missing

[latent latch]

you need at least one thing to have a rigidbody

can be kinematic

[high summit]

ah

let me try that rq thanks

[latent latch]

otherwise, you can just do like a overlapbox operation

[high summit]

figured rigid body was for physics and stuff

part of me thinks I should've chosen an easier first project but part of me is really having fun with the complexity

[latent latch]

collider is part of physics too, but yeah I don't know why the trigger method has to be so connected to it

[high summit]

something like this is fine tho?

[latent latch]

ye

could always remove them later too

[high summit]

alright nice, sort of works

just gotta make it only instantiate one door somehow

and also fix the prefabs that have the doorpoint slightly too low

[lean sail]

I realized a flaw with my scriptable object game effects which are "when X happens do Y". I wanted to make a feature, every few seconds heal some amount. Since im using SO, i realized there is only one instance so every character with this effect will add to the counter. Then one character ends up consuming the health and the timer resets.
I need unique instances and know I can Instantiate(SO) or CreateInstance but is there a reason to use one or the other? I assume Instantiate is the same but it copies the data from my existing SO which I want.
Also are there any downsides to use Instantiate here? It seems to work so far but I am just curious if there is something else I need to do. Like do I have to destroy the objects after?

[latent latch]

Instantiate usually copies anything serialized usually (much like prefabs) while CreateInstance is like making a new SO instance in the editor as it'll always have defaults

defaults from the original SO instance

dont quote me on this ;)

I did actually make a effect system using SOs only but I ditched that idea for just plain ol' c# classes

[high summit]

I'm kinda struggling on this end. Any advice?

Issue is that both doorpoints register the collision and go through their process, which involves spawning the door

so two get spawned

[lean sail]

i might just create some poco based on the effect if i notice any errors

[latent latch]

public class DoorSpawner : MonoBehaviour
{
    public bool QueuedForDestruction = false;
    private void OnTriggerEnter(Collider other)
    {
        if(QueuedForDestruction) return;

        if(other.TryGetComponent(out DoorSpawner door))
        {
          Destroy(door.gameObject);
          door.QueuedForDestructon = true;
        }
    }
}```

[latent latch]

try something like that

or some similar idea

[high summit]

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

public class DoorSpawner : MonoBehaviour
{
    [SerializeField] private GameObject doorPrefab;
    private bool doorBeingSpawned = false;

    private void OnTriggerEnter(Collider other)
    {
        // Check if a door is not already being spawned and the colliding object is another DoorPoint
        if (!doorBeingSpawned && other.CompareTag("Door"))
        {
            // Set the flag to indicate that a door is being spawned
            doorBeingSpawned = true;

            // Destroy the colliding DoorPoint and its associated doorFiller objects
            Destroy(other.gameObject);
            Destroy(transform.parent.gameObject);

            // Instantiate a new Door prefab at the position and rotation of this DoorPoint
            InstantiateDoor();
        }
    }

    private void InstantiateDoor()
    {
        // Instantiate the Door prefab at the position and rotation of this DoorPoint
        GameObject door = Instantiate(doorPrefab, transform.position, transform.rotation);

        // Reset the flag to allow for the next door to spawn
        doorBeingSpawned = false;
    }
}``` this is what I currently have but spawns two doors anyways

[latent latch]

so it's not the door checking OnTrigger but this DoorSpawner?

there's no race conditions that I'm aware of

[high summit]

All rooms have doorfillers and those fillers have doorpoints as children. If two overlap, that means a door should go there, so all of those should be destroyed and a single door spawned

I have a dumb idea for a solution

have each generate a random number when they collide and the lower number gets destroyed

rock paper scissors for life

[latent latch]

im not too sure, but something to run step by step in the debugger if needed

[high summit]

Ugh I've been trying to use a coroutine or invoke to add a delay in order to spawn one door but the coroutine return makes the following line unreachable, and the invoke just doesn't work and idk why. ```cs
private void OnTriggerEnter(Collider other)
{
if (!doorBeingSpawned && other.CompareTag("Door"))
{
doorBeingSpawned = true;
Destroy(other.gameObject);
Destroy(transform.parent.gameObject);
Debug.Log("Invoking InstantiateDoor");
Invoke("InstantiateDoor", 0.1f);
}
}

private void InstantiateDoor()
{
    Debug.Log("Instantiating door...");
    // Instantiate the Door prefab at the position and rotation of this DoorPoint
    GameObject door = Instantiate(doorPrefab, transform.position, transform.rotation);
    // Reset the flag to allow for the next door to spawn
    doorBeingSpawned = false;
}```

In this code the first debug prints but the secont debug never does

Tried with coroutines earlier but those didn't work either and idk why

[rigid island]

you destroy the whole parent ?

[high summit]

thats one of the steps that has to happen yeah

[rigid island]

can't invoke if its destroying

[high summit]

should I change the order

Just tested with the parent destruction happening second to last but still doesnt work

[rigid island]

wdym second to last?

[west lotus]

You cant run a coroutine on a Monobehaviour that is gonna get destroyed next frame and expect it to wait for 0.1s or what ever

[high summit]

before the flag set to true

[high summit]

Idk how to do this im ngl I've tried like 30 different things in the last hour

[rigid island]

why do you need delay

You could also make the whole TriggerEnter a coroutine

[high summit]

This script is attached to every door spawn point, if theres no delay two doors spawn at every spot

[latent latch]

there doesnt need to be delay

[west lotus]

I think we need a hit more context on your set up, code and what you want to achieve

[latent latch]

there's no race conditions

[rigid island]

that means something is triggering twice when it shouldnt?

delay might be hiding a bigger issue

[high summit]

I provided a couple screenshots above

[high summit]

Every doorpoint has the script attached to it, and they each check for a collision

so when a collision happens rn it leads to double trigger

[rigid island]

you can check gameobject IDs and only run function on one script

[latent latch]

for the most part, Unity is single threaded (as far as user-space callbacks go) , if it happens on a single frame then it's probably executing in some order

[rigid island]

https://unity.huh.how/physics-messages#i-am-receiving-a-message-twice

[latent latch]

oh that's a pretty good idea

[high summit]

Sounds like a better alternative to my rock paper scissors idea thank you lmao

And it worked

[high crow]

Hello i just have a question about unity netcode im trying to add a force to an object with a severrpc as the client has no rights. but it just isnt the player is being referenced properly and the m value is correct and changing with the rest of my code if anyone has any tips please help. btw the function is being called in update.
public void movementServerRpc(Vector2 m,ServerRpcParams serverRpcParams = default){
var clientId = serverRpcParams.Receive.SenderClientId;
if (NetworkManager.ConnectedClients.ContainsKey(clientId)){
var client = NetworkManager.ConnectedClients[clientId];

        client.PlayerObject.GetComponent<Rigidbody2D>().AddForce(m,ForceMode2D.Force);
    }
}

extra info:
i have got a network trasform on the object and it is not updating the postion in the sever
its not just the add force trying to change the trasform also does nothing although it is being called as the debug.log is working

[limber wharf]

hey guys, so I want to directly download from OneDrive using this method:
https://api.onedrive.com/v1.0/shares/u!XXXXX/root/content
where XXXXX is the base 64 equivalent of the url
however when I convert the url to Base64URL format and try to open the final url, it responds with:
{"error":{"code":"unauthenticated","message":"The caller is not authenticated."}}

Any idea how to fix this?

[quartz folio]

Presumably you are not authenticating with OAuth2 and are not providing the correct token in the request

[limber wharf]

how can I do that?

[quartz folio]

https://learn.microsoft.com/en-us/onedrive/developer/rest-api/getting-started/msa-oauth?view=odsp-graph-online

I googled "onedrive api authentication"

[limber wharf]

isn't there some simpler way of downloading directly from onedrive? or maybe use different storage?

[high crow]

ok an update on the problem it is infact increaceing the veloctiy but not changeing the position which i didnt think was possible

[limber wharf]

Did you try impulse mode instead of force?

[high crow]

i dont really know why this would change anything as adding the force is not the problem it is that fact that when it is added it doesnt change the position

[limber wharf]

I had the same problem and just changing it to ForceMode2D.Impulse fixed it for me, perhaps are you sure there isn't any code that is manipulating with the object's position?

[lean sail]

#archived-networking but you probably shouldnt be doing multiplayer if you arent really confident in coding/debugging. what you are doing in the server rpc doesnt really make sense, this script can just have direct access to the rb. The same way it does in single player. Then you can just add force in like fixedupdate based on a network variable (for the vector2)
If a person does not own the object, it will not move the object no matter what you assign to the velocity.

[lean sail]

There is code that is doing it. The entire networking framework

[high crow]

i im relatively confident with unity and debugging but i am trying to learn networking i thought i would use a sever rpc to add the velocity as when i use a network transform it is quite delayed if you think it is a ownership problem it would be great if you could help me understand it better in #archived-networking

[lean sail]

I dont really do networking anymore, you should just post it there regardless

[high crow]

thats all good thats for the tips anyway

sorry but noone was helping

[knotty sun]

not the point

[terse aurora]

that's the script of my camera, but if I use collision.gameObject.CompareTag("change1") it will detect camera's collisons, how to get the collisions of my Player?

because like this it doesn't work

[quartz folio]

You can only get the collision occurring to this object. Your way of writing it the other way is just nonsense

[terse aurora]

yeah I noticed that getting just the y position would be enough, now it works, I'm so dumb

like this

[swift falcon]

    {
        if (Input.GetMouseButtonDown(1))
        {
            Vector2 MousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
            Vector3 direction = MousePosition - (Vector2)transform.position;
            float angle = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;
            Quaternion rotation = Quaternion.AngleAxis(angle, Vector3.forward);

            _rigidbody.MoveRotation(Quaternion.RotateTowards(transform.rotation, rotation, _rotationSpeed * Time.deltaTime));
        }
    }

I may be stupid. but for some reason this is not working. it gives me this error.

Player.RotateTowardsCursor () (at Assets/Scripts/Player/PlayerMovement.cs:58)
Player.FixedUpdate () (at Assets/Scripts/Player/PlayerMovement.cs:29)

[hard viper]

the line with an NRE contains the variable that is the problem

[void turtle]

Why is everyone using public variables for ScriptableObjects? Like this looks like a big sin for me.

[hard viper]

in this case, line 58

[hard viper]

it is 🙃

[swift falcon]

I checked and nothing is there

line 58 is: Vector2 MousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);

[hard viper]

then add a breakpoint, look at debugger, and see what the contents of your variables are

[swift falcon]

it was working before and now it is not so idk

[void turtle]

yeah the { get; } getter is not working and the only option seems to be setting up manual getters?

[hard viper]

they should all be [field: SerializedField] public int myVariable {get; private set;}

it needs a private setter to actually define the backing field and connect to unity

[void turtle]

okay thanks

[warm kraken]

hey guys. there's a lack of collider primitives in unity. is there a good asset with primitive colliders? what would you recommend?

[heady iris]

3D collider primitives are provided by PhysX.

so you aren't going to be adding your own primitives

[knotty sun]

what knid of primitives are you looking for?

[warm kraken]

cylinder cone donut etc

usual stuff

[knotty sun]

make em in blender then use a Mesh collider

[warm kraken]

what if i want to change cylinder collider's shape size and offset like im able to do with default colliders in unity?

[rigid island]

cant

[warm kraken]

yep. thats why i asked if you guys know the best pack for it. i searched and there are several. im trying to get a primitive collider pack where you have flexibility with size and shape

[knotty sun]

make new ones, one of the best optimizations you can make in Unity is to use models which have not been modified

[warm kraken]

so my custom blender colliders will be more optimized than default ones in unity?

ok then

[rigid island]

mesh colliders are expensive, tread carefully. The basic ones unity has are always more performant

[heady iris]

Primitive colliders are shapes that are easy for PhysX to reason about.

I imagine they were chosen for a reason.

Toruses, notably, are not convex.

Cylinders are harder to reason about than capsules.

[static matrix]

I seem to be getting a lot of perf hog on Physics2D.FindNewContacts any idea what might be causing this?

AHAAAAAAAAAAAAAAAAAAAAAAAAAA
I'VE FIGURED OUT THE BUG
when the linerenderer is turned off, it counts as the renderer turning off, triggering "OnBecameInvisible" and starting the countdown for the offscreen kill

so I just need to tell it to reset the offscreen-ness when the linerenderer goes away

[polar wadi]

Hey. I would like to hide the objects between camera and player. How is it called and how could I do this best? I tried with ray cast but that only works semi good

[rigid island]

depends what effect you want, there are shaders for this or you can do it manually with a few raycast/ capsulecast

it will proably be easier with some sort of cutout shader though

[polar wadi]

I tried it with a shader. But with that the walls are cutout strangely

[rigid island]

idk what strangely means

[polar wadi]

one moment

well

for some reason now it works as expected

XD

before in play mode it was messed up

i saw like two cutout cirlces

an inner and outer and between them the wall was there

[rigid island]

could be it needed playmode to work properly

[polar wadi]

it was in play mode XD

[rigid island]

the preview sometimes may not do justice

oh weird

[polar wadi]

now i can reproduce it

It was due diffrent cutouts in materials

[rigid island]

oh so you only need 1 ?

[polar wadi]

No I had two materials with diffrent cutout size. so it somehow messed it up in render

[rigid island]

ahh gotcha

[polar wadi]

but anyway. thanks for resonding 🙂

[main pawn]

Hey, I've noticed some weird behaviour with AudioSource.isPlaying. Basically, I'm using it to play random sounds from a set one after another. It will play the first sound, then check isPlaying until it can play the next ones. But it never gets to the next one.

Even if the source is totally silent

Any ideas?

[rigid island]

isPlaying going to false or wat

[swift falcon]

Alright, this is my current code:

    private void Awake()
    {
        _rigidbody = GetComponent<Rigidbody2D>();
    }

    private void FixedUpdate()
    {
        SetPlayerVelocity();
        RotateInDirectionOfInput();
        RotateTowardsCursor();
    }

    private void SetPlayerVelocity()
    {
        _smoothedMovementInput = Vector2.SmoothDamp(
            _smoothedMovementInput,
            _movementInput,
            ref _movementInputSmoothVelocity,
            _time);

        _rigidbody.velocity = _smoothedMovementInput * _speed;
    }

    private void RotateInDirectionOfInput()
    {
        if (_movementInput != Vector2.zero)
        {
            Quaternion targetRotation = Quaternion.LookRotation(transform.forward, _smoothedMovementInput);
            Quaternion rotation = Quaternion.RotateTowards  (transform.rotation, targetRotation, _rotationSpeed * Time.deltaTime);

            _rigidbody.MoveRotation(rotation);
        }
    }

    private void RotateTowardsCursor()
    {
        if (Input.GetMouseButton(1))
        {
            Vector2 screenPosition = new Vector2(Input.mousePosition.x, Input.mousePosition.y);
            Vector3 worldPosition = Camera.main.ScreenToWorldPoint(screenPosition);
            Vector2 playerPosition = new Vector2(transform.position.x, transform.position.y);
            Vector2 direction = ((Vector2) worldPosition - playerPosition).normalized;
            float angle = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;

            Quaternion rotationmouse = Quaternion.AngleAxis(angle - 90, Vector3.forward);

            _rigidbody.MoveRotation(Quaternion.RotateTowards(transform.rotation, rotationmouse, _rotationSpeed * Time.deltaTime));
        }
    }






    private void OnMove(InputValue inputValue)
    {
        _movementInput = inputValue.Get<Vector2>();
    }
}

Whenever my character touches another object (especially a corner of an object) it starts randomly spinning

[rigid island]

lock rigidbody rotation on Z

[swift falcon]

that locks all my rotation haha as my code rotates the rigidbody

[rigid island]

nvm

[swift falcon]

nope

oh alright

[crude mortar]

if your character is a circle anyways than you don't really need to rotate it with physics

if you do want to use physics, you could just override the rigidbody angular rotation at all times

[swift falcon]

how would i make it so it rotates without physics?

[rigid island]

could've sworne MoveRotation would still work with locked Z

[crude mortar]

lock the rotation like what was recommended earlier, then just manually rotate the rigidbody

[crude mortar]

and maybe try this, I am unsure if it works as well

[rigid island]

nah they have that already thats why i was confused

[crude mortar]

oh, I didn't read the code up there

[swift falcon]

got it

set rotation moves when its locked

move rotation doesnt

but the problem is

that removes my dampening

[rigid island]

yea ig because MoveRotation still uses physics

[crude mortar]

doesn't seem like it should remove your dampening.. or at least I wouldn't expect it to. should be same rotation getting calculated, just applied differently

[swift falcon]

how would one fix it?

[crude mortar]

well, explain what you mean by dampening exactly

if you mean the rotation is instant now for some reason, maybe you accidentally got rid of your RotateTowards.. ?

[swift falcon]

nope

it is instant

but i did not remove

the rotatetowards

i think its because rotatetowards uses physics (maybe?)

[crude mortar]

no (it doesnt use physics)

can you show code that actually compiled?

        }
    }






    private void OnMove(InputValue inputValue)
    {
        _movementInput = inputValue.Get<Vector2>();
    }
}

[crude mortar]

what if you just do transform.rotation = rotation for them instead, and also double check your rotation speed (although I doubt thats the issue)

[swift falcon]

uh no

that fucked everything up

ill send a vid

[crude mortar]

well yeah.. your camera is a child of your player (it will inherit rotations)

how was it not doing that behavior before?

[swift falcon]

tbh idk, my camera doesnt get affected by my player's rigidbody rotation or position

[crude mortar]

that is very weird considering in this video from earlier I can see the player rotation changing in the transform https://cdn.discordapp.com/attachments/763495187787677697/1221490801721475214/2024-03-24_17-04-35.mp4?ex=6612c4f5&is=66004ff5&hm=5abae5a3a56c77076b5d6c15a77d0fdd44d7b656bf83f95454d985dc27326690&

[swift falcon]

i know

also this fucks it up as now if i hold right click (which changes the rotation to where my mouse is) while moving it bugs out

which it wasnt doing with the physics

[crude mortar]

probably mostly luck that it was working before, your logic is incomplete. You should only rotate towards one or the other (either movement direction or mouse direction)

right now it tries to rotate towards both when you hold the mouse button

[swift falcon]

no it was actually good the way it was

lemme switch back and show you

[crude mortar]

no

[swift falcon]

alright

[crude mortar]

I am saying that it was just luck that it appeared to look good, it was still actually trying to rotate to 2 different directions at the same time

the delay of the interpolation physics must have made it unnoticeable

you should wrap your "RotateInDirectionOfInput" code in a if (!Input.GetMouseButton(1))

[swift falcon]

yeah thats what i was about to do

ty

I actually don't know how but now the dampening works with
_rigidbody.SetRotation(rotation); so 🤷‍♂️

thank you anyways <3

[crude mortar]

glad it works

[merry sierra]

do any one know how to solve this bullet issue

void FireBullet()
    {
        foreach (var point in ShootPoints)
        {
            Debug.Log(playerRigidbody.velocity);
            var bullet = Instantiate(bullets, point.transform.position, point.transform.rotation);
            bullet.AddForce(playerRigidbody.velocity + (point.transform.forward * bulletSpeed), ForceMode.Impulse);
        }
    }

[rigid island]

doesn't seem the pivots are correctly placed?

[merry sierra]

by pivots u mean firepoints?

[rigid island]

and bullet

[merry sierra]

nah they are placed correctly when i am not moving it works perfectly fine but when i move things get messy

[rigid island]

thats local pivot or center ?

[merry sierra]

local pivot

[rigid island]

you tried also without playerRigidbody.velocity in addforce ?

[merry sierra]

yeah same thing

[rigid island]

do you have a trail or somerhing?

it looks like the bullet is shooting fine is just the trail lagging

[merry sierra]

yeah trail is child of bullet

[rigid island]

yeah I think thats whats causing that "look" but the bullet is shooting fine

try speed up duration time you will seee it will prob be better

[heady iris]

the trails last too long, yes

[merry sierra]

yeah its better but theres still a delay

[rigid island]

they're weirdly rotating

[merry sierra]

i think that is because the car is rotatating and they always go forwards so its an illusion i guess

[rigid island]

when i need to debug something fast i have mapped keys for Time.timeScale = 0.05f or something

[rigid island]

looks like it starts lagging behind yea

you try increase the bullet speed?

[merry sierra]

yea i already doubled it

[rigid island]

you're passing the rotation of now not the one you're going to be in. by the time it happens the car already rotated , I think..

never tried shooting rigidbodies on moving objects like this, i typically go for raycasts on that. So I'm not sure

[merry sierra]

with raycast cant show that a turret is shooting

[rigid island]

sure you can

[merry sierra]

but i have to move the bullet manually and it will also lag i guess

like from starting point to the end point

[rigid island]

you can simulate it faster than a physics object can accelerate in physics loop

[merry sierra]

or to just add muzzle flash and hit effect to fake it?

[rigid island]

like the lines right?

[merry sierra]

yeah lines

[merry sierra]

didn't understand what u meant here

[rigid island]

you can make instant ones too or give them a slight delay , but never tried on rotating object that adds extra challange

[rigid island]

for example you could lerp the trail renderer between start + end (a point on ray)

ideally cause Update will run more frequent should be able to move it faster than a rigidbody can accelerate (accounting for mass ig)

[merry sierra]

hmm will try with raycast which ever feels better will use it

[rigid island]

worth a shot

ForceMode.Impulse is taking mass into account another thing to consider

[lunar python]

is it only me whos not seeing a problem with the bullets

[rigid island]

bullet is spawning behind the firepoint

also you're def passing the wrong rotation or the pivot you showed me was in global mode @merry sierra

physics... a double edge sword

[merry sierra]

yeah that i was trying something now i put bullet firepoint bit more forward

it looks much better and with muzzle flash it will look better

[lunar python]

have you tried putting it in late update

[merry sierra]

yeah its in late update only

[rigid island]

why is that?

[merry sierra]

so that the movement will take place first and then it will get update position to spawn

[lunar python]

it looks as if the bullet is coming out a bit slow like the prefab of lazer has its origin set at center and when it is instantiated, half the lazer is behind the muzzle

And when the object is instantiated, its next fixedupdate would be called in the next cycle right?

[merry sierra]

private void FixedUpdate()
    {
        if(!isReloading)
        {
            timer += Time.deltaTime;
            if(timer > firerate)
            {
                timer = 0;
                currentMagazine -= 1;

                FireBullet();

                if(currentMagazine <= 0)
                {
                    isReloading = true;
                    reloadtimer = 0;
                }
            }
        }
        else
        {
            reloadtimer += Time.deltaTime;
            if(reloadtimer > reloadingTime)
            {
                reloadtimer = 0;
                timer = 0;
                currentMagazine = maxMagazine;
                isReloading = false;
            }
        }
    }

I put this loop in fixed update

[lunar python]

why is time.delta in fixedupdate

[heady iris]

it's fine

Time.deltaTime is set to be Time.fixedDeltaTime whilst FixedUpdate is running

[lunar python]

what there is that feature?

[heady iris]

small suggestion: instead of doing timer = 0, do timer -= firerate

Imagine the fire rate is set so that you fire 49 times per second

you fire on physics update 0

at physics update 1, you're almost ready to fire again, but not quite

at phyiscs update 2, you fire, and you reset the timer to 0

so you only fire 25 times per second

[merry sierra]

will implement that

[heady iris]

If you rate of fire can be greater than 50, also consider using a while loop until timer < firerate

that way you can fire many times in one step

[merry sierra]

thanks for the help guys

[lunar python]

if you instantiate an object on frame 0, then apply force to it on frame 1, would it takes until frame 2 for physics to take place?

[merry sierra]

🤔

[lunar python]

oh you also apply force on frame 0 so that would make it frame 1?

[heady iris]

Physics doesn't happen on frames at all.

Physics updates happen 50 times per second by default.

well..it does happen during a frame; it's just that you can have zero, one, or many physics updates happening in a single frame

https://docs.unity3d.com/Manual/ExecutionOrder.html

Looks like physics happens before the normal update loop

So if you apply a force on frame 0, and Unity decides to run a physics update on frame 1, the force will be used at that point.

[lunar python]

well im talking about physics frame of course

[golden glade]

I'd like to have a billboard world screen UI facing the camera, however my current issue is that there are multiple cameras (split-screen game), is it possible to make the world screen space Canvas UI with split-screen, if so .. How? If not, what other way would you suggest to show a text above the player which should be the amount of people taken out?

[lunar python]

he instantiate object in fixedupdate, which kinda sounds like this thread https://www.reddit.com/r/Unity3D/comments/dfk1h2/object_a_gets_instantiated_in_fixedupdate_but_the/

[rigid island]

put two versions of script, one only seen by cam1 and one only cam2.

[golden glade]

Hmm, good idea. Although would that not hurt the performance having multiple canvases for each player?

[merry sierra]

is it multiplayer?

[golden glade]

So if I had 4 players, I'd have to spawn 4*4 canvases

[golden glade]

couch co-op

[lunar python]

how much player could it possibly

[rigid island]

you already have two cameras thats already pretty performance heavy

you're only rendering 1 on each cam, not both

give it a try

[golden glade]

4 players max

[golden glade]

fair

[heady iris]

you can really just do one big canvas that you have multiple smaller regions in

multiple canvases will also work. either way, you need to make sure each player's UI is properly sized.

[lunar python]

i would recommend multiple canvas though. cuz if something change in a canvas, the whole thing gets redrawn

[golden glade]

I already have a canvas for each players view and assigning camera layers per player

[heady iris]

Yeah. I actually need to go profile this...

I use one huge canvas for my main menu

[golden glade]

My game already has a performance hit with 2 players running on a 1070 laptop

[heady iris]

I do deactivate almost all of the individual menus, though

[golden glade]

So I'm kind of worried about whether the performance will go down the drain

[lunar python]

https://unity.com/how-to/unity-ui-optimization-tips

[golden glade]

The game is a 3D co-op "bomberman" like game

I have already implemented object pooling so at least thats no issue for now.

[rigid island]

make the game, use profiler to catch anything

[lunar python]

the first optimization tip is seriously split canvases

[rigid island]

don't not make something simply for premature optimizing

[golden glade]

Done

[lunar python]

my game dont even have canvases yet cuz everytime I add a canvas, the pixels gets jaggy

and distorted

[golden glade]

Each player has its own canvas.

I think most of the performance issues comes from unoptimized models thanks to MagicaVoxel.

around 4.7M verts in total, and the bombs generate around 500K verts (each).

[lunar python]

wtf

[golden glade]

There are a lot of particles

[lunar python]

where did you even grab those bombs, it could bomb your pc you know?

[rigid island]

that is kinda horrible, is the environment at least set to static ?

[golden glade]

Yes

[lunar python]

i remember the 2 million vertices toothbrush in a yandere game

[golden glade]

The bomb model itself is just a sphere model with a flat shader

the particles are the issue

[lunar python]

just make a triangle bomb

better for performance

[golden glade]

Invisible bomb 🧠

[wicked river]

Hey! I am looking for a fairly standard way to manage variables. Ammo, health, Death state, items collected.

Do I careate a game Manager state and store all the player specific variables in this file and then load and save using this class or do people just shove variables into random classes as they develop and just accept that things might get messy 😅

[somber nacelle]

you put the variables on the objects where it makes sense to have them. for example you wouldn't have both a Player Health and Enemy Health variable on the same object as that would generally not make any sense

[lunar python]

we do daily code renovations, so just do what you think is suitable

[wicked river]

sure, this makes sense. The variables I am focusing on mainly is persistant data for the player .
Ammo, health, lives, points, XP

Inventory items

[lunar python]

you generally want to have input in seperate files from your player data, just create a player controller for handling external influence, a data manager for each entity, and a input controller

[sterile sorrel]

you dont want players to be able to directly modify their stats in online games just through their local code

[somber nacelle]

you can have a single object that is used purely to save/load that data. but most of it wouldn't be on the same component unless you're writing some terrible god class that does everything

[wicked river]

I get that. Reason for me asking is, I find that I have randon variables everywhere that the player needs . Stupid example : I have a isDead boolean sitting on a gameState Manager class. I have player health script on a UI component that gets updated via an Event and I have an inventory system set up on a INventoryManager . Now I need to write these data sets to a file to save and load and I find myself looking everywhere trying to keep track of everything. I am 100% going to miss stuff upon saving and loading this way

[wicked river]

Ya, so no god class! Promis XD

[hardy pendant]

Hihi I have a question
A video explaining it or a general explanation would be great

So in games, for example stardew valley: after/during a certain triggered event a building in the map changes/upgrades

Whats the simplest way to do this?

[sterile sorrel]

https://hastebin.com/share/galabuviti.csharp

I need some help instantiating the GameObject inside the chunk length float please

[wicked river]

The easies way is to have the trigger or event be called at the end of an animation or sequence . In this case a video will play and toward the end have code call the new 'sprite/3D gameObject' to replace the current one

[leaden ice]

What does that mean?

BTW Start is capitalized incorrectly

[lunar python]

health script on an UI element?

sounds like recipe for disaster

[wicked river]

Yup!

I was nooblet when I wrote some of the code. so I am trying to fix my stuff

[hardy pendant]

Okok thank you!
I had assumed it would be similar to that but I wanted to ask since im not the most experienced code wise

[lunar python]

I assume you are an artist getting their hand at game dev right

[sterile sorrel]

I just threw that in, in the actual code it's correct

I'm trying to instantiate the trainStat1 prefab in a certain length. It is currently instantiating on any empty game objects with the tag "trainStat1", that works but it does it in other places I don't want it to. So how do I limit the length it instantiates?

[hardy pendant]

Me? If so, Yeah I am

Ive dabbled in visual novels quite a bit but I wanted to try my hand at something more hands on

[lunar python]

you could start from learning MouseToWorldPosition to get position of mouse, Raycast to get the gameobject you are pointing at, learn some basic UI stuff to make buttons pop up after click, add functions to buttons and change sprite to desired ones

I think thats what you are looking for

[lunar python]

visual novels?

like the click ones that you get from scenes to scenes

[hardy pendant]

Yeah smth like that

Im a studio arts major alongside a creative writing major so it was a pretty naturally coming gateway into game design

[lunar python]

well thats a good start, I guess you already knows most of the basics

[leaden ice]

I have no idea what is means to "instantiate in a certain length"

[lunar python]

upgrading building doesn't make much difference from updating conversations in visual novel though so idk what you need help with

[sterile sorrel]

Im instantiating an object, and i want to make it spawn inside of a certain length

objects wont be instantiated here | | | objects will be instantiated here | | |objects wont be instantiated here

[hardy pendant]

I was mostly asking about the general concept as I wasnt sure what route was/would be the most efficient

[lunar python]

i dont quite get what you are meaning

like pattern for instantiating?

[sterile sorrel]

public GameObject[] trainStat1;
public float chunkLength = 90;

void Start ()
{
GameObject[] trainStat1EMPTY = GameObject.FindGameObjectsWithTag("trainStat1");

foreach (GameObject position in trainStat1EMPTY)
{
        int randomIndex = Random.Range(0, trainStat1.Length);
        GameObject randomPrefab = trainStat1[randomIndex];
            Instantiate(randomPrefab, position.transform);
    }

}

In this code, I am Instantiating prefabs into any empty object with the tag trainStat1
that works
but I have separate chunks, so it then spawns into that one and the others too
I need it to only instantiate inside of the chunk length

[sick edge]

Is it better to make base classes or static classes for cross script communication?

[lunar python]

read the docs about the Instantiate function, im quite sure you are getting it wrong on the second parameters

[sterile sorrel]

you really arent understanding me are you

yeah, no nothing helpful there

I need it to only instantiate prefabs inside of the chunk length

[lunar python]

the just check if the position.transform.position is inside of chunklength

[sterile sorrel]

and how would i do that?

even if i checked that and then let it instintiate it would still instantiate outside of the chunk into others

[cobalt goblet]

Anyone made a distortion 2d mask before or has any idea how I could? Trying to make a distortion/glitch effect that can either fully or partially distort/glitch objects or areas in my viewport?

[lunar python]

then check if the bounds of the object in a position overflows into others

[sterile sorrel]

so how would i do that?

[lunar python]

depends on the object shape

[craggy veldt]

holy Arceus! 😄

2d or 3d?

[golden glade]

3D

[craggy veldt]

they're instanced?

how many drawcalls?

just curious 😌

[golden glade]

4.4k verts before the bomb explosion

[craggy veldt]

OP bomb 👏 it can explode verts counts too 🙌

[golden glade]

Okay, removed all particles. Now it doesn't even go above 10K

[dry mural]

god, making my own custom implementation of pathfinding using multithreading is such a pain in Unity. (pathfinding must be custom, that's for my thesis)
i'm proud that it's finally working as intended and can handle up to 192 bots queueing path at almost the same time

[static matrix]

oncollision enter also counts if a collider in a child object hits something right?

[knotty sun]

if the script is on the same gameobject as the Rigidbody, yes

[toxic vault]

Need some help with mouse aiming in my top down game. It 'almost' works, but there's some bug where it consistently fire off target by a few degrees.

Shooting towards bottom of screen or left of the screen, the bullets feel only very slightly anti-clockwise from my cursor.

Shooting towards the top of screen or right of screen, the bullets are a lot more anti-clockwise from my cursor.

This is my aiming code where I just turn the play to face in direction of where my mouse cursor is.

 Plane playerPlane = new Plane(Vector3.up, transform.position);
            Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
            float hitDist = 0.0f;

            if (playerPlane.Raycast(ray, out hitDist))
            {
                Vector3 targetPoint = ray.GetPoint(hitDist);
                Quaternion targetRotation = Quaternion.LookRotation(targetPoint - transform.position);
                targetRotation.x = 0;
                targetRotation.z = 0;
                this.transform.rotation = Quaternion.Slerp(this.transform.rotation, targetRotation, rotateSpeed * Time.deltaTime);
            }

And this is code for where I actually shoot out bullets from my gun -

GameObject projectileInstance = Instantiate(projectile, bulletSpawnPoint.transform.position, Quaternion.identity);

            
projectileInstance.transform.rotation = StaticUtilities.GetCrewLeader().gameObject.transform.rotation;
            

            Quaternion pelletRotation = Quaternion.AngleAxis(UnityEngine.Random.Range(-spreadFactor, spreadFactor), Vector3.up) * projectileInstance.transform.rotation;

            projectileInstance.transform.rotation = pelletRotation;

[leaden ice]

Why are you doing cs targetRotation.x = 0; targetRotation.z = 0;

You shoulkd never be touching parts of a quaternion like that

delete that

[latent latch]

surprised that even works

[toxic vault]

Because I want the rotation only around Y axis. It's top down game, the X and Z rotations for player don't matter

[leaden ice]

Oh this is also wrong

[leaden ice]

nah you have that covered already with the plane raycast

but this is wrong:

            if (playerPlane.Raycast(ray, out hitDist))
            {
                Vector3 targetPoint = ray.GetPoint(hitDist);
                Quaternion targetRotation = Quaternion.LookRotation(targetPoint - transform.position);```

oh wait nvm that's ok

just delete that weird quaternion code that is definitely wrong and broken

x and z on a quaternion aren't what you think

[toxic vault]

I'll be very honest, Quaternions and angles confuse the heck out of me. A lot of this is copy pasted and modified from other examples on the internet. Maybe some chatGPT mods

[leaden ice]

Ok and I'll be honest, delete these lines, they're very wrong

See if that improves anything

[latent latch]

wouldnt you specify that the z is the up axis though if this is 2D

for look rotation

[leaden ice]

I assume 3d top down

[latent latch]

ah ok

[leaden ice]

with gameplay on the x/z plane

[fallow flame]

Hello everyone, not sure if this is the right channel for this but I got a question. I want to make a camera look at and render ONLY a UI canvas, how do i do that?

[leaden ice]

Just use a Screen Space - Camera canvas

And use a culling mask to make the camera only render that UI

[toxic vault]

No, didn't help. No difference - good or bad

What would help with troubleshooting? One thing is the weapon is not centered exactly on the player. Does it need to be?

[leaden ice]

well yes that's a problem. That means of course this caculation would be off

perhaps you should be aiming the gun at the cursor

[toxic vault]

The bullet does rotate in same direction as player though. So weapon being at a wrong angle should not matter?

projectileInstance.transform.rotation = StaticUtilities.GetCrewLeader().gameObject.transform.rotation;

[fallow flame]

how do i stop these balls from appearing around my game object??

[quartz folio]

This is not a programming question. Disable the gizmos for light probes

[fallow flame]

Okay sorry and thank you

[leaden ice]

yes same direction as the player but since it's offset to the side, it will miss the target

[toxic vault]

Yeah, I see that now. My weapon was at a slightly different angle than the player. And the Ray calculation from center of player to cursor. So a lot of slightly whacked calculations

First, I am going to make weapon and player angle the same way.

Second, in my calculations, I am going to measure from where bullet spawns to the cursor, keeping it all consistent.

Let's see how that works out.

[rich leaf]

Hey. I’m curious as to how people here like to approach their inventory systems they design for games. Not looking for a YouTube tutorial as I’ve followed them before.

Just want to hear people’s thoughts on how they approach this (not detailed code but high-level descriptions, ie using scriptable objects for xyz, dictionaries for this, etc)

[viscid tide]

Hey sorry if this sounds dumb but I'm new to this so looking for some help. Basically I have a texture that I need to check every single pixel for it's green value then add it to a float. Since my texture is 1440x1440 pixels it has to do that ~1.9 million times which is way to much. So my idea was to scale down the texture to 100x100 pixel. It will still keep the original texture but just be a worse quality. I did something looking around but I can't find anyway to do this. Would what be the correct approach to achieve this? Thanks!

[leaden ice]

basically:

• ScriptableObjects for the "base" data for items, i.e. its name, the UI sprite for it, the effects it has, the max stack size, etc.
• a serializable, runtime Item class for runtime instances which has a reference to the base data SO, may contain runtime data like durability, use count, etc.
• As for the inventory itself it depends how you want it to work but it could be anything from a Dictionary<Item, int> to a List<Stack> where Stack is a struct with an item reference and a quantity.

[rich leaf]

Thanks!

[lethal rivet]

Sorry for the code screenshot, but I didn't know how else to show the values during the debug process. As you can see in the variables watcher to the left, leftOffset is 0 but for some reason when I assign it to attached (a RectTransform), it sets it to NaN and it disappears in the scene. Anybody know why this is happening?

[leaden ice]

Looks like this is the value

leftOffset is NaN

not 0

[lethal rivet]

Well yeah, but I don't see why that would happen. All the variables that calculate leftOffset are 0, and I'm not dividing by 0 anywhere.

One sec

[leaden ice]

x Nan
y -

[leaden ice]

you'd have to show how it's calculated

[lethal rivet]

float leftOffset = positionOffset.x - (sizeOffset.x * anchor.x);```

According to VS code positionOffset.x is 0, sizeOffset.x is 0, and anchor.x is 0.

[leaden ice]

one or more of these things is NaN to result in NaN here.

[lethal rivet]

Is VS Code being a little silly and changing NaN to 0 when I hover over a variable?

[leaden ice]

doubtful

[lethal rivet]

guh

[leaden ice]

make sure it's NaN at the moment you're debugging

the code could be running multiple times

and not be nan every time

[lethal rivet]

I'll check

I don't know if this is a valid way to do it, I debug.log Time.time and then collapsed the output to see any repeats and I got no repeats. Does that mean it's only running once per frame? Is there a better way to check?

[cosmic rain]

time and delta time are updated once per frame. What exactly are you trying to do?

[lethal rivet]

I was just checking if a certain piece of code was running more than once per frame, I didn't know how else to do it.

[cosmic rain]

Maybe check/print the frame number?

[lethal rivet]

Didn't know that was a thing.

I'll try it

[cosmic rain]

It's good to check the API docs from time to time. There's a lot of useful stuff you can discover.
https://docs.unity3d.com/ScriptReference/Time.html

[lethal rivet]

Ok yeah no repeats.

I have absolutely no idea why this is happening. A value is 0, I'm appplying it to a rectTransform then it turns into NaN

[cosmic rain]

It could be that some other values are invalid causing a NAN internally. Like the anchors.

[lethal rivet]

I see. If that's the case I'm just going to do a band-aid patch I don't think I want to debug something happening behind the scenes.

[cosmic rain]

That was just a guess. I don't k ow the whole context.

It looks like you had a NAN in the debugger, so it's probably your code and not something internal.

[lethal rivet]

Dang... I'll keep looking I guess.

Thank you for your help.

[cosmic rain]

Share the whole script. Maybe there's something obvious.

[lethal rivet]

Sure one moment I’m moving around at an airport

[latent latch]

Negative values probably problematic too beyond zero division but I wouldnt think it turn nan

[cosmic rain]

It's not entirely clear what exactly is being NAN I'm that screenshot. Is attached a rect transform?

[lethal rivet]

Yes

[cosmic rain]

And the pop-up window is of what variable?

How do I set up my sprites / tilemaps in unity so the thing that gets shown in front is by the pivot that has a lower Y.

[latent latch]

it's in project settings somewhere

global transparent sorting axis

[swift falcon]

isn't that just for the Y position? not the pivot

[latent latch]

https://www.sunnyvalleystudio.com/blog/how-to-sort-sprites-in-unity

oh, the pivot you need to do it independently for each sprite in the sprite editor

and then on the sprite renderer you sort by pivot

[swift falcon]

oh ok i got it thanks

[cosmic rain]

I'd reset the values in the script to those of the rect transform or some safe values the first time it's attached. You're likely calling SetRectValues while some of the fields are initialized with default values which could be invalid. For example, anchors having size of 0 could be the source of the issue.

[hardy pendant]

hihi I just have one more quick question
ok so im trying to find information on a general concept I want to add to my game but nothings coming up when I look it up so im confused if maybe my english is failing me or if its just not something easy to do?
I want to add favorability bars to my game (if that term rings no bells think like how stardew valley has the heart system or how bg3 has the trust bar)
but I cant seem to find any videos or threads on it?

I dont think its a rare concept so im wondering if im just calling it the wrong thing maybe?

[rain minnow]

it's just a bar like health that updates based on a stat (value). there isn't anything different or special about it. you track and update it the same way, similar to the approval rating for dragon age . . .

you won't find a specific tutorial about it since it's just a stat value—shown visually with a bar—used for a custom system in certain games . . .

[hardy pendant]

That actually makes so much sense why didnt I think of that lmao

thank you btw!

(also Approval rating is a way better term than what ive been saying it makes a lot more sense to)

[hard viper]

i have a simple class for a reactive value for this sort of thing

[rain minnow]

it's like a morality system. some characters will have a morale stat . . .

[hard viper]

ReactiveValue<T>, which holds a private field of type T, and public setter. If the public setter tries to set an actually different value, it invokes a public event action, to notify anything that needs to know that the value has changed.

[hardy pendant]

yeah I know, my english was just failing me a bit and "favorability bar" was somehow the best I could slot in for my mind to work lol

[rain minnow]

yeah, i noticed i kept making a property/field setup with events over and over. much easier to make a reactive/observable class and struct to use instead . . .

[hard viper]

i got the idea from Fen or Burrito, I think

burrito is especially big on reactivity systems

[hard viper]

affection is another name, if it is romantic. like harvest moon

approval is more political

[hardy pendant]

yeah I was gonna add both (trust and romance one), but had to sort out what I was actually doing first and it didnt click in my mind that you can just set it up basically like (using Random's example) a HP bar

[hard viper]

a lot of games don’t use a bar/number, and hide the fine details. Usually you only get an indication at specific thresholds

more information => min max affection.
less information => more relaxed/vague

[chilly surge]

Oh hey, glad to see more people are adopting reactivity systems 😄

[hardy pendant]

yeah thats true, I just really like how bg3 did it and they used a visible kinda slider-esc bar

[hard viper]

i said his name 3 times, and he popped out of the mirror

[hardy pendant]

LMAO

bro was summoned

[hard viper]

KEKW
pretend this server has that emote

[hardy pendant]

I got you lol

anyways huge thanks to both you and random, im off now to do the gruelling work that is
✨ designing a city ✨

[rain minnow]

i just need to refactor it into some old stuff (if i feel like it) and my core package which i use for all my projects . . .

[hard viper]

it is not worth refactoring, but it is worth making it, and adding it in to anything new

it’s just cleaner, and less spaghetti

[rain minnow]

i don't do 🍝 , though, i'll eat it, like i am right now . . .

[hard viper]

fyi, my vanilla reactive value also has a field for default value, to call ResetToDefault

default being defined in constructor

every variable I want to be a reactive value winds up wanting this behaviour

[rain minnow]

that makes sense . . .

When I use a vertical scrollrect with elastic - there's some amount of "buffer" that I can drag past the top of the content. Empirical testing shows it's some.. magic number, about 500 pixels? Is there a way to set/get it programmatically so I don't just have to guess and hope that it works for all sizes?

(I'm currently putting a background on the content rect that's top/bottom -600/-600 but I'd prefer to exact-size it)

[latent latch]

seems like something I'd just toss in double its value and call it a day

maybe ive done that before actually

[agile carbon]

Hey guys. I’m working on an interesting project simulating cars precisely. So, I have a function that runs and matches up the rotation of the wheels to the speed of the car and vice versa (I’ll take slip into consideration later), but my problem is that when cars steer, the car rotates a little bit as you turn. But in Unity, since I’m custom programming the rotation and movement of the car, I also have to code the rotation of the car. What’s the best way to go about the steering?

Rotating the chassis is the greatest problem

[modern creek]

yeah, probably gonna be fine.. double will be too much though since the actual content is typically like 5000px

[mighty tide]

do you have the front tires rotating and the back moving cares in real life

[modern creek]

but i use these everywhere in my app and the .. lack of a data point to specify the "above-scroller" is kind of annoying

[agile carbon]

Wdym?

[mighty tide]

so basic the back wheels push the car and the front wheels rotate the car

[agile carbon]

In essence tho my configuration rn is awd

Well I guess 4wd is more accueste

[mighty tide]

yeah

but it works for most cars

[agile carbon]

So what will happen is my wheels will rotate. Now there is ackermann steering which is based off of a point and then ig there is other steering

So if I were to rotate the wheels I could theoretically figure out which way the car should go but figuring out how much it rotates is different

[mighty tide]

basiclly unity's physics will calculate most of it

[agile carbon]

How

[mighty tide]

the wheels will use the rigidbody

[agile carbon]

I already have the wheels setup that isn’t the problem

It’s how the chassis rotates

And how the back wheels follow the rotation

[mighty tide]

i'm not sure maybe you should look up a youtube video

[agile carbon]

Have

[cosmic rain]

Shouldn't it be rotated in the direction of the movement?

public class WallHit : MonoBehaviour

        {
            Destroy(other.gameObject);
        }
    }
}

i am using this script to destroy my bullet but for some reason its not happening any idea

[thorn stirrup]

How would I use OnDrawGizmos to draw a circle for a collisionPt?

[latent latch]

if you're debugging points of collision you can always instantiate a gameobject and throw a script onto that that constantly draws the sphere at the location

[sterile crown]

you put on trigger enter on the box, but you did not set the box's box collider to be trigger, make the bullet a non trigger and the box a trigger and it should fix it

tldr swap triggers

[thorn stirrup]

What do you exactly mean by throw a
Script on an instantiated game object? Sorry, bit of a novice

I understand how to instantiate a new game object in code, but how would i add a script to it programmatically?

[latent latch]

Instantiate(GizmoPrefab, col.gameObject.position, Quaternion.Identity)

[thorn stirrup]

I see

[latent latch]

make a prefab that contains a script for the gizmo

[thorn stirrup]

Ahh duh haha.

[latent latch]

you may want to add its own timer to expire though

[thorn stirrup]

Makes sense

Cant i destroy it after a few seconds?

[latent latch]

yeah, the gizmo prefab script can hold all that and destroy itself

also, probably parent them to something so they don't spam the scene :)

[thorn stirrup]

Thanks so much for talking through it with me

[dense estuary]

I fixed that, however, I am experiencing a problem with my radar where the icon appears within 90 degrees of the ray. Here is my code: cs private void CreateAndMove(Collider collider) { Vector3 colliderPosition = collider.transform.position; Vector3 desiredPosition = colliderPosition - new Vector3(player.transform.position.x, 0, player.transform.position.z); Vector3 position = this.gameObject.transform.TransformPoint(desiredPosition / (scannerRange * transform.localScale.x)); var angle = Vector3.Angle((colliderPosition - player.transform.position).normalized, Vector3.forward); if (Mathf.Abs(angle - ray.transform.rotation.eulerAngles.x) <= 1f) { StartCoroutine(PingDuration()); if (pingVisible) { Instantiate(badGuy, position, transform.rotation, transform); } } Debug.Log("Angle: " + angle); } void RotateRay() { ray.transform.Rotate(0, rotateSpeed * Time.deltaTime, 0); }
Is there a version of Vector3.angle that is always a value between 0 and 360?
(I know its been like 14 days, I'm sorry.)

[round magnet]

what do you get if you change var angle = Vector3.Angle((colliderPosition - player.transform.position).normalized, Vector3.forward);
to
var angle = Vector3.eulerAngles((colliderPosition - player.transform.position).normalized, Vector3.forward);
?

[ocean hollow]

eulerAngles isnt a Vector3 func...

[round magnet]

looks to me like the docs begs to differ. but I also just woke up so I might be confused about it :p

[somber nacelle]

you are creating and destroying a brand new Texture2D every single time you call this
just reuse the Texture2D object

[ocean hollow]

i omitted some code that sets the value of the read pixel to the the value of a referenced material

[dense estuary]

Yeah, thats not a thing.

[ocean hollow]

https://docs.unity3d.com/ScriptReference/Transform-eulerAngles.html if youre talking about this, you have to create the var yourself

[somber nacelle]

yeah if you want help optimizing your implementation, then don't omit code when sharing it

[mild holly]

https://gdl.space/zuyurunide.cpp

[ocean hollow]

i editied it so that its the original now

[somber nacelle]

okay and how often do you start this coroutine

[mild holly]

I am trying to make a system where if the Energy is online, the energy online container object should be active else it should say that energy is offline

The interactable object implements two interfaces

[ocean hollow]

            {
                StartCoroutine(PickColorCoroutine());
            }```

[somber nacelle]

great, so every single frame that the button is down. #archived-code-general message

[ocean hollow]

yes, i was mentioning when you said to just reuse the same texture#archived-code-general message

[somber nacelle]

none of what you have said would prevent you from reusing a Texture2D that you create instead of creating and destroying one every frame. you create a ton of garbage by doing that

[mental rover]

additionally, have you read: https://docs.unity3d.com/ScriptReference/Texture2D.ReadPixels.html

ReadPixels is usually slow, because the method waits for the GPU to complete all previous work first. To copy a texture more quickly, use...

[ocean hollow]

private IEnumerator PickColorCoroutine()
        {
            // Wait until all rendering is complete
            yield return new WaitForEndOfFrame();

            if (tempTexture == null)
            {
                tempTexture = new Texture2D(1, 1, TextureFormat.RGBA32, false);
            }

            // Calculate the correct position to read from based on the mouse position
            Vector2 mousePosition = Input.mousePosition;
            Rect readPixelRect = new Rect(mousePosition.x, Screen.height - mousePosition.y, 1, 1);

            // Read the pixel from the RenderTexture
            tempTexture.ReadPixels(readPixelRect, 0, 0);
            tempTexture.Apply();

            // Retrieve the color from the texture
            Color pickedColor = tempTexture.GetPixel(0, 0);

            // Set the brush color
            brush.Color = pickedColor;

            foreach (Renderer visualizer in colorVisualizers)
            {
                if (visualizer != null)
                {
                    visualizer.material.color = pickedColor;
                }
            }
        }

i couldve sworn i implemented this before i went with my current solution (i did) and my frames still tank by the same amount

[ocean hollow]

thanks i'll take a look

[swift falcon]

how do I stop this from happening? (this referring to the light overlapping the object and going through it.)
my object has a collider.

now i would try a shadow cast but it doesn't work great either (as you can see in second pic), like i want the light to follow the red lines and not light up the object like that

[next salmon]

Thats not how lights work

[swift falcon]

well

[next salmon]

In no dimensions do shadows look like what you want them to

[swift falcon]

i know

im not trying to make it a light

im trying to make it a field of view marker

[next salmon]

Its still right

[swift falcon]

not really. if you stand behind a door way you will see a somewhat straight line

it doesnt expand unless you are really close to it

[mellow sigil]

The second screenshot is accurate to how the line of sight would work in real life. If you want something different you'll have to code it yourself

hey guys?

anyone can say me what i need todo, that i can fold in and out the Headers in inspector?

[thin aurora]

Configure your !ide first

[tawny elk]

💡 IDE Configuration

If your IDE is not autocompleting code
or underlining errors, please configure it.

Select one:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)
• VS Code
• JetBrains Rider
• Other/None

[dense tapir]

lol? that is configured xD i just use the dark mode xD

[thin aurora]

Common Unity types are not correctly highlighted so your editor is not configured to use Unity

[dense tapir]

if i turn the dark mode then the highlighted colors are normal xD but that broke my eyes xD

so pls dont try to find any problems where i dont need/have help/problem

[thin aurora]

It's not about finding irrelevant problems, you're expected to have a configured editor if you want to receive help. It also benefits you as the user a lot to have everything set up correctly.

[dense tapir]

Please just answer my question and stop worrying about any crap

[knotty sun]

Have a look at Naughty Attributes, they have a Foldout attribute

[dense tapir]

is that an asset in unity store?

[lean sail]

https://github.com/dbrizov/NaughtyAttributes

[deft timber]

why is your naming conventions so inconsitant

[thin aurora]

Because his editor is not correctly configured to suggest correct naming /s

[deft timber]

nah, he just uses dark mode Kappa

[chilly surge]

FYI if they are using VS Code and using a theme that does not support semantic highlighting or turned off semantic highlighting altogether, then it falls back to simple TexMate grammar based syntax highlighting and will not highlight Unity types differently because it won't have syntax information. Not saying that's definitely the case here, just saying it doesn't always mean IDE is not configured.

[thin aurora]

Interesting, I never seen that happen but that sounds reasonable behavior from VSCode

[chilly surge]

In VS Code you can even turn off all highlighting so it's just black and white, but still have full language server diagnostics and error reporting. It's extremely configurable.

[fathom patrol]

Hi all! What would be the best and safest way to insert something into a MySql database running on a server from a standalone Unity Application?

[quartz folio]

Sounds awful lol

It annoys me when you can't tell value types from reference types, let alone not even differentiating types from members

[knotty sun]

have a backend website that interacts with both Unity and MySQL

[fathom patrol]

do you have any sources for getting started with that? I'm not that familliar with web-development

[knotty sun]

what OS is your database running on?

[fathom patrol]

Ubuntu Server

Ubuntu 22.04.4 LTS x86_64

[dense tapir]

thank you

[chilly surge]

Yeah realistically no one sane would do that and just use semantic highlighting like a normal person. But having TexMate grammar highlighting is what allows VS Code to give (not very good but better than nothing) syntax highlighting for practically every popular language and file format in the world without having a language server for every single one of them.

[knotty sun]

Ok, then probably Node.js is best for you. it has easy access to both http and MySQL
https://nodejs.org/en
https://www.w3schools.com/nodejs/nodejs_mysql.asp
https://www.w3schools.com/nodejs/nodejs_http.asp

[chilly surge]

It also allows me to open a 1 million LoC C# file (artifacts, not actually source code) in less than a second and have good enough syntax highlighting to work with, rather than having to wait for language server to slowly process the entire file. VS could never do that.

[thin aurora]

You could set up a .NET API running behind Apache, then you can continue working with C#. Remember anybody can reach your web application so some form of security should be added.

.NET has solid support for MySQL and also things like PostgreSQL and SQLite. There's a general framework that's "usually" used called Entity Framework which provides a code-first solution to database communication and it makes it super easy to work with.

[fathom patrol]

i see - thank you both!

[wild warren]

i have two web requests in unity, one of them gets back an image url from the internet the other one downloads it and turns it to a texture, my problem is the second one doesn't wait for the first to fetch

[leaden ice]

What makes you think that?

[wild warren]

i run the code, it gets to the second part and it gives me n error says it cant fetch url or whatever because it's empty and then after a while the url is generated

[knotty sun]

wdym 'the url is generated' ?

[wild warren]

okay let me explain this further, i'm using amazon s3 bucket to store users profile picture, my bucket is private which means i can't fetch images directly from there, so for that i wrote an api in nodejs, to access the image and create me a temporary url for that image, in unity first i run that api to fetch the url and then i need to download it to display the image as a raw image texture,

[knotty sun]

sreenshot the console so I can see the Debugs

[wild warren]

i call the first part which is getting the image url, then i call gettexture to download the url and display it as texture, but if you look at the console log it ran the second part then the url got fetched

[knotty sun]

this does not seem to be in any way related to the code you posted

[wild warren]

yes i changed it abit, i seperated the first part and second and put them in two IEnumerator, but still nothing changes, same result

[long hare]

why the pixel perfect is showign up like this ?

[knotty sun]

you've made it worse, the second coroutine will run before the first has completed.
Also how do you expect us to help you if you do not provide correct code

[leaden ice]

This new code is much worse than the original code which would have worked properly

[long hare]

these are the options for the pixel perfect

[wild warren]

@knotty sun @leaden ice okay here is the orginal code and it's still the same.

[knotty sun]

not quite the same, you took out the most important information. The Debug.Log of URL passed back

@leaden ice

[leaden ice]

Ok but are you turning in the project or the built game

This is honestly a question for your teacher

[brave shadow]

both

@leaden ice

[leaden ice]

Then make a build and put the build folder and the project folder into a zip archive together, what's the issue

[brave shadow]

i tried that but when i open the build file its blank ;-;

as i open it says made with unity then a blank template ;-;

[leaden ice]

Sounds like you didn't build the game properly

Probably didn't include your scenes

[brave shadow]

i did..

[brave shadow]

@leaden ice what if i wanna share my file

so the teacher can look throught the file

[leaden ice]

That's what I explained how to do

I don't see what's complicated here

[leaden ice]

Prove it

it is default empty scene probably

[leaden ice]

If you don't know why did you include it in the build?

so where is the project

💀

[leaden ice]

You tell me friend

It's your project and your computer

Where'd you put it?

[brave shadow]

should i just upload the game?

💀

[leaden ice]

You should talk to your teacher not us.

[brave shadow]

ok

[agile carbon]

Yes

[cosmic rain]

Then do it

[agile carbon]

But that’s too general

You can’t rotate the car in the direction until the car moced

And at that point you are going in increments so I would need to calculate the amount it needs to rotate and then do it per frame

But simultaneously get the direction in which the wheels need to move as well as make the back wheels follow

[sturdy gorge]

For some reason I'm facing this issue. Where I update variables in my code it doesn't reflect on the unity hub. The DeadZone here is -30 but it is reflecting -20 on the UI.

No idea why this is happening.

[oblique spoke]

Serialized values override initialization values in code

[heady iris]

public float florp = 100;

This declares a field named florp with a field initializer that sets it to 100.

Field initializers are applied during the creation of the object.

Unity applies serialized values after the object is created.

"serialized" meaning "saved", basically

anything that shows up in the inspector (if you aren't doing any Wacky Custom Editors, at least) is a serialized value

The field initializer will only matter when creating new instances of the component, or when you right click the component and hit "Reset"

[sturdy gorge]

Sorry new to game dev didn't get it.

Does that mean the value that's in the Unity hub?

[oblique spoke]

Fen explained it in detail. Values in the Unity editor override those default values in code.

[heady iris]

suppose I create a component called "Example"

using UnityEngine;

public class Example : MonoBehaviour
{
    public float myField = 123;
}

When I attach the "Example" component to a game object, Unity stores some data.

you can actually just drag a scene or prefab aset into a text editor to look at it

MonoBehaviour:
  // a bunch of other junk
  m_Script: {fileID: 11500000, guid: 816d62879a223453490b2d4b131c57d0, type: 3}
  myField: 123

Unity records that "myField" contains a value of 123

If I then edit the value in the inspector, the serialized data changes.

so if I change "myField" to 100, it remembers the value.

MonoBehaviour:
  // a bunch of other junk
  m_Script: {fileID: 11500000, guid: 816d62879a223453490b2d4b131c57d0, type: 3}
  myField: 100

That's what it means to be "serialized": the data is stored.

If I made that "myField" private, then:

• myField would not appear in the scene or prefab data at all
• Unity would not remember a value for myField
• myField would not show up in the inspector

Unity has to turn this scene or prefab data into actual objects.

It does this by:

1. Creating the object
2. Assigning all of the serialized values into it

[heady iris]

In step 1, Unity creates an Example object. At this moment, myField has a value of 123.

[heady iris]

In step 2, Unity looks at the saved data and restores all of the saved values. myField is now 100.

[sturdy gorge]

So, it basically stores the value that I assign first time (which is called serialization)?

So, if I do public float myField = 123; I will have to reset every time?

[heady iris]

If you don't want Unity to remember a value for each instance of your component, you should tell it to not serialize the field at all.

By default, private fields aren't serialized.

You can use also use the [System.NonSerialized] attribute.

[sturdy gorge]

Yes, but private won't be present in the inspector. Right?

So, change it from code every time.

[heady iris]

A non-serialized field won't show up in the inspector, yes.

since unity doesn't save it, there'd be no point in displaying it in the inspector: you couldn't do anything to it

[sturdy gorge]

Yes, that'll be the 'ideal' behavior for me. I'm not sure if everyone thinks the same but say in other coding that I do changing the variable reflects and overrides the values present. There also we have 'inspect' but as soon as we change something in the code (and save) it reflects soon overriding anything that we did in the inspect.

I'm not sure if thinking in that terms is good.

[heady iris]

this sounds more like what you'd expect from a debugger

yes, that's not the right way to approach the inspector

The inspector is used to configure components.

You create scenes and prefabs that contain GameObjects. GameObjects have Components attached to them.

Components have serialized fields that you assign values and references to.

[sturdy gorge]

Okay, but say I did some stuff on the inspector like changing the value and now I found the ideal settings. Now I wanna 'save' that. Say the code is present on github. Saving won't happen right? Since the code still has value 10 while in the inspector say I changed the value to 15.

[heady iris]

version control isn't relevant here at all

If you want to change the default value the field will have when you create new instances of the component, then change the field initializer

This won't affect any existing instances.

so if you decide you want myField to default to 15, change it to public float myField = 15;

Any new instances of your component will start out with a value of 15.

[sturdy gorge]

This is confusing kind of lol

[oblique spoke]

Serialized values of existing instances (scene objects, prefabs, etc) will be stored in .scene/.prefab/.meta files, which will be pushed to your source control.

[heady iris]

well, no, they just live in the actual scene and prefab assets

[heady iris]

The field initializer provides the default value. You'll get that default value if nothing replaces it.

That's all.

[sturdy gorge]

Okay, so if someone else decides to run my game locally. (Again, new to game dev so I might be throwing general dev concepts that don't apply) Then they'll see 15 on the unity hub and 10 on the code. Is that it?

[heady iris]

"run my game locally"?

i don't know what you mean.

[sturdy gorge]

Say pull my code and test it.

[heady iris]

Do you mean if they check out your project from source control and open the editor?

[heady iris]

They'll see exactly what you see.

[sturdy gorge]

Yes, ''

[heady iris]

The serialized values are part of the scene or prefab. Scenes and prefabs are assets. Assets are put into source control.

[oblique spoke]

All of that stuff should be replicated through version control. Only personal editor preferences and caching files may be left out.

[sturdy gorge]

Okay, so 15 on the inspector and 10 on the code?

[heady iris]

Yes. They'll see exactly what you see in your own editor.

[sturdy gorge]

Okay, that makes sense.

[heady iris]

Unity would be completely unusable if you couldn't make changes to scenes and prefabs (:

[sturdy gorge]

Yeah, I am just trying to relate it with core dev stuff that I do at work. Here, from my understanding so far, the inspector matters a lot compared to dev. So, you dw reset it after you change a variable in the code I'm assuming.

[heady iris]

If you want to discard the serialized data for that specific instance of the component, then yes, you'd reset it.

[sturdy gorge]

So, if I want to apply the values that are in the code. I'll have to press reset everytime?

[sturdy gorge]

Ohh I think that's what I just asked haha

[sturdy gorge]

this

[heady iris]

If you don't want to serialize the field, then mark it non-serialized.

The inspector is used to configure an object. It's not intended to be a list of every single field the class has.

[sturdy gorge]

Okay, got it. Thanks for the help.

Hey, im using a roslyn code generator to generate this sample class right here:

using UnityEngine;

namespace EntityFramework {
    public class ComponentList {
        public static void Main() {
            Debug.Log("");
        }
    }
}```

Whenever i generate it though it gives me this: https://img.sidia.net/ZEyI5/DOyUwaCa97.png/raw (Show references: https://img.sidia.net/ZEyI5/nozaRopu17.png/raw)

There is only one file, if I modify it by hand it is the same regardless of what reference i follow

This is the code generator: https://gdl.space/tozaqozoke.cs

Hey, Im using URP and I have a Camera which is disabled and I render its view to RenderTexture using camera.Render().
The problem is it renders Gizmos as well. How can I prevent it?

[dense tapir]

just for info, for the ppls who need it too...

i found a easy way to solve the problem!
so if anyone need it and dont wanna use third person assets, just ask 🙂

[mellow imp]

why do we use InvokeRepeating() in void Start() instead of void Update()I never understood the reason behind that.

[spring creek]

I don't understand.

You can use it in either

But probably shouldn't use it at all

Use coroutines instead

Or just CALL the method in update I guess

[mellow imp]

i got no clue what those are, I'm just following the Junior Programmer pathway in Learn Unity

and for some reason they use invokerepeating in start rather than update

like it can still be multiplied by time.deltatime so i dont understand why that is

[spring creek]

Well that is the opposite of what you said originally. Doing it in start makes more sense. Start tins once

[mellow imp]

oh wait, does invokerepeating just keep on running forever if it's called just once?

[spring creek]

https://docs.unity3d.com/ScriptReference/MonoBehaviour.InvokeRepeating.html

[heady iris]

read the documentation for the methods you are using

[past barn]

InvokeRepeating and Execution stuff

[heady iris]

you should get used to doing this; using tools without actually knowing what they do is going to make game development completely miserable

[mellow imp]

that is surprisingly simple

[mellow imp]

alright, thank you!

i will keep that in mind

[violet junco]

Hi devs! I don't suppose someone could impart their wisdom and help me with something? I am trying to make my first person character controller work with an Xbox controller. I have everything working with PC but when I connect my controller, my movement and jump is already set up, but I need to find a way of getting the right analogue stick to work with the camera. Would anyone be able to help me out with getting this to work? I'm hoping that once learning this, I can teach future students with this method for their projects 🙂 TIA!

[sage latch]

With the new or old input system?

[violet junco]

New input system 🙂 I’ve tried to follow tutorials online but nothing seemed to work!

[sage latch]

The channel for that is #🖱️┃input-system ;)

[violet junco]

First time using the Discord, still navigating everything! 😄

[silver cloud]

I'm wondering, is there some way to programatically change width and height of a RenderTexture with a downscaled resolution (e.g. 192x108 for 1920x1080 display) whilst keeping the size same for just larger scales of a resolution (e.g. still 192x108 for 3840x2160)?

[heady iris]

I don't understand what the goal is here. Don't you just want it to be a constant 192x108, then?

Or do you want lower values for smaller initial resolutions?

[silver cloud]

I want it to be 16:10 when the display is 16:10

[leaden ice]

Looks like RenderTexture.width and height are both writeable.

you can also just make a new one based on some calculation

[heady iris]

oh, so you want a fixed aspect ratio

with a roughly constant total amount of pixels?

[silver cloud]

no, I meant an aspect ratio to match the display

How do I make the calculations?

[heady iris]

so you need to solve for width * height = total and width * ratio = height

two unknowns, two equations

[silver cloud]

ok

[heady iris]

width = height / ratio, so you get height * height / ratio = total

height = sqrt(total / ratio)

given that, you can get

width = total / height

there will be some rounding error here

so you might not get exactly total pixels

[silver cloud]

so I floor that?

[heady iris]

I would round it, I guess

[silver cloud]

ok

[dense tapir]

a little Trash-Post...
just wanna show you the result from my inspector editor 😛

[worthy willow]

My NavMeshAgent AI follows a waypoint in the Update function, but if the Waypoints Y value is too high (over 2.4 I think) it stops following the waypoint. Is there a way around this?

[hexed pecan]

Might wanna snap the waypoint position onto the navmesh with NavMesh.SamplePosition

[worthy willow]

lol as soon as I posted this I thought about just making a new vector3 thats the waypoint x and z values only and Y is kept at 0 and it gives the result I want

thanks for your input though

[worthy willow]

I might use this actually instead of keeping the y value at 0

[hexed pecan]

Likely this only works if your navmesh Y is near 0

So I would still use SamplePosition

[solemn raven]

Hi
is it possible to make a custom editor for classes that is not inherited from monobehaviour ?

[hexed pecan]

Nope, you would need a custom propertydrawer

Unless it is a scriptableobject or something

[solemn raven]

@hexed pecan I just wanna mention it on other script
i have script called "Setup" which has a custom editor , inside this script I mention another class that is not monobehaviou public Writer writer; the custom editor of main has this line EditorGUILayout.PropertyField(writer); ... << this line is returning error "NullReferenceException: Object reference not set to an instance of an object"

I found that if I made writer a monobehaviour the problem is gone

[hexed pecan]

Is Writer serializable?

[solemn raven]

also if I remove the custom editor the problem is also gone

[solemn raven]

I tried to add [System.Serializable] to it but instead giving me a spot where i can drag and drop the componenet, it gave me all variables in the writers

[hexed pecan]

Ok I thought you wanted to show the variables

You want it to be draggable?

[solemn raven]

yes

[hexed pecan]

Okay then Writer should be a MonoBehaviour or a ScriptableObject

[solemn raven]

no other way around it ?

I'll have to added monoBehaviour just for that ?

[hexed pecan]

Well, where would you drag it from if it wasn't a mono or SO?

[solemn raven]

ohhh good point
ok thank you so much ^^

[solemn raven]

but its kinda odd tho as without custom editor i can drag and drop it even if it's not monobehaviour

i thought something is missing in my editor

[hexed pecan]

Not sure

Hi, I'm really not sure where to ask this or what to do about it, so I'm asking here. I'm trying to lerp the feet's position to anchors that follow the hips after they reach a certain angle difference. The first problem I have is managing correct movement timing; I'm looking to make each feet move if the opposite is grounded. I also have issues with moving the character while lerping the feet, as they use an incorrect world position, and makes feet go to an old position. The last issue can seen at about 00:46.

Currently using animation rigging for the head, neck, and hip look direction, and code for making the feet face the correct direction. Any help or tips are greatly appreciated :)

[distant pasture]

thinking of implementing a restart button intra scene: can I just do my script for go to x scene and choose the current one and it'll restart? we have no other scripts to save from scene to scene so i'd imagine it would just restart if I do this, but I'm new to unity so im not sure

[tired moss]

Yep, telling the scenemanager to load the current scene will reload it

[rigid island]

link it inside the inspector so you know its fully connected

[sly igloo]

hey, thank you, but I´m not sure, what you mean by that?

[sly igloo]

Everything else is working fine with the slider. I just want to know how to access the navigation.

[rigid island]

Ohh I never used that in script sry

thank you anyway, the visuals ony allowed one 😦

Hi. I want to make a card game and I'm having trouble with revealing cards.
They're supposed to reveal in a certain order, but they all get revealed at once. I tried putting WaitForSeconds(), but they still get revealed at the same time.
This is the loop that handles this. The Reveal() function just flips it and makes the parameter isRevealed true.

for (int j = 0; j < cardCount; j++)
        {

            GameObject localCard = cardSlots.transform.GetChild(j).gameObject; //Find the unrevealed card

            if (localCard.GetComponent<CardProprieties>().playedOnTurn == currentTurn.Value)
            {
                yield return new WaitForSeconds(1); //wait 1 second

                localCard.GetComponent<CardProprieties>().Reveal(); //Reveal card

                int cardPower = localCard.GetComponent<CardProprieties>().currentPower;

                if (side == 0) 
                {
                    location.GetComponent<LocationClass>().localPower += cardPower;
                }
                else
                {
                    location.GetComponent<LocationClass>().enemyPower += cardPower;
                }

            }
        }

[sly igloo]

yield return new WaitForSecounds(1);

Will only work by using a Coroutine

I have a problem and I want to know if someone can help me. I have a GameController that use Singleton so it has the DontDestroyOnLoad(gameObject); code. But when I change from one scene to another scene that have a GameController, the new GameController is replaced by the GameController from the scene before. This provoke that all the references from the objects in the new scene that use methods of the GameController are broken and missing. Sorry if this is a bit confusing, but if someone understand it, how can I solve it?

[hard viper]

what singleton class are you using?

[hard viper]

https://github.com/LoupAndSnoop/GenericDataStructures/blob/main/Singleton
Try this singleton

[neon zinc]

That's is how I create my Object

[hard viper]

1. that is why is is destroyed
2. use the singleton class I sent you

it would be
public class GameController : Singleton<GameController> {

this singleton derives from monobehaviour

[neon zinc]

Ok, I will take a look of it, thank u so much

[neon zinc]

I see how it works, is a compact but so clever solution. Thank u again for sharing your work

[hard viper]

ty. i got it from someone else, and made small modifications to it

[grave tundra]

That's remarkably similar to my SingletonBehavior

Wow heh.

using UnityEngine;
using JF.Logger;

namespace JF.UnityCore.Behaviour {

    /// <summary>
    /// A singleton Monobehaviour that automatically creates an instance of itself the first time instance is referenced

            get {
                if (_instance == null) {
                    // First try to find the instance in the scene.
                    _instance = FindObjectOfType<T>();

                    // If the instance doesn't exist, create a new gameobject and add the component
                    if (_instance == null) {
                        GameObject obj = new GameObject(typeof(T).ToString());
                        _instance = obj.AddComponent<T>();
                    }
                }

                return _instance;
            }
        }

        private static T _instance;

        virtual protected void Awake() {
            if (_instance == null) {
                _instance = this as T;
            } else if (_instance != this) {
                JFLogger.Error(
                    new string[] { "JFAutoSingletonBehaviour", typeof(T).ToString() },
                    "There can only be one instance of type {0}. This MonoBehaviour will be destroyed", typeof(T).ToString()
                );
                Destroy(this);
            }
        }

    }

}

Like, eerily similar haha

[golden garnet]

Hey guys. Asked this a couple times before but got no solid answer. Lemme try again... Does anyone have any idea how to fix this?

hastebin link is dead now but i could resend if needed

[hard viper]

i recommend having a special break for if the application is quitting, because you can get infinite loops when closing from things calling GetInstance as they are being destroyed

[grave tundra]

Yeah i see that in the other example

[hard viper]

my game had some infinite loop crashes as it closed instead of closing properly as a result

[grave tundra]

You know, I have had a couple infinite loops for no reason recently

[hard viper]

That will do it

that is why i also have TryGetInstance

TryGetInstance tries to get the instance, but does NOT try to make a new instance if it can’t find it.

I only call TryGetInstance in things like OnDisable, OnDestroy, and related to avoid infinite loop shenanigans

[grave tundra]

I appreciate the examplanation, I'll add it.

[hard viper]

one last little thing: a lot of people like their singletons to be automatically DontDestroyOnLoad

My game has >50 singletons, and only 2 are DontDestroyOnLoad

[grave tundra]

Yeah, I just usually put it in Awake of the singleon itself

        override protected void Awake() {
            base.Awake();
            DontDestroyOnLoad(this);
        }

[hard viper]

Yeah. Definitely do NOT copy that from my implementation. I’m stuck with it because I don’t want to refactor.

[grave tundra]

Haha you could refactor in like 20 mins if you bite the bullet 😄

[hard viper]

yeah, but i don’t feel like it lol

the only parts that are actually important are the ones i mentioned about app quit and trygetinstance

[grave tundra]

Yeah I added those to my like 7 year old file, thanks! 😄

I think I've gotten kinda lucky since I don't often tear these down

[hard viper]

Is there a specific component needed for TMP Input Field to work?

i put down a gameobject with a TMP Input Field component, but I think there is something else missing

[latent latch]

create it from the asset menu

[grave tundra]

Perhaps a silly question here: do I need to cache results from Addressables.LoadAssetAsync, or will unity handle that?

[latent latch]

https://learn.unity.com/tutorial/load-addressable-assets-in-scripts
Yeah mean this?

m_LogoLoadOpHandle = Addressables.LoadAssetAsync<Sprite>(m_LogoAddress);
m_LogoLoadOpHandle.Completed += OnLogoLoadComplete;

private void OnLogoLoadComplete(AsyncOperationHandle<Sprite> asyncOperationHandle)
{
    if (asyncOperationHandle.Status == AsyncOperationStatus.Succeeded)
    {
        m_gameLogoImage.sprite = asyncOperationHandle.Result;
    }
}

[grave tundra]

Not exactly. I mean what I load the same asset many times (say a reused tree prefab)...

[mighty juniper]

Hey all. I'm trying to setup object pooling for the first time and this was my attempt at setting up a system that allows for it to be relatively expandable with multiple pools, curious on your guys' opinion. Whether i've done any bad practices, how I could potentially improve, etc. Thanks

using System.Collections.Generic;
using System.Linq;
using UnityEngine;

public sealed class ObjectPool : MonoBehaviour
{
    public static ObjectPool instance;

    private void Awake()
    {
        if(instance == null) instance = this;
    }


    [System.Serializable]
    public sealed class Pool
    {        
        [HideInInspector] public GameObject[] objects;

        public int count;
        public GameObject prefab;
        public string identifier;

        public void CreatePool()
        {
            objects = new GameObject[count];
            for(int i = 0; i < count; i++)
            {
                GameObject obj = Instantiate(prefab);
                obj.transform.parent = instance.transform;
                obj.SetActive(false);
                objects[i] = obj;
            }
        }

        public Pool(string identifier, GameObject prefab, int count)
        {
            this.identifier = identifier;
            this.prefab = prefab;
            this.count = count;

        }
    }

    public void AddPool(string identifier, GameObject prefab, int count)

    }

}

[lean sail]

https://docs.unity3d.com/ScriptReference/Pool.ObjectPool_1.html
there is already an object pooling class, very easy to implement

if you wanted to stay with yours,
i suggest getting away from using a string for the ID. Maybe you can just use the prefab as an ID
then you can use a Dictionary<GameObject, Pool> instead of having to search through a list to find the pool you want

[mighty juniper]

Oh alright, thank you.

[mighty juniper]

The issue with this was that it wouldnt let me serialize a dictionary, but i suppose i could use a struct

[lean sail]

also instead of checking which is activeInHierarchy, you can keep a collection of objects only usable in the pool. Remove them from the pool as they are gotten, then have them returned when they are finished being used. This way you've immediately gotten rid of searching through objectPools and searching through the pool itself

[lean sail]

there are serialized dictionaries online, but you could use a list for the editor and build the dictionary based on the list. The dictionary itself doesnt need to be serialized

[mighty juniper]

Makes sense thanks again

[mighty juniper]

Do you mind explaining how i would go about using a prefab as the id, what property of it should i use?

[lean sail]

any property of it that you want, you could just directly do Dictionary<GameObject, Pool> or Dictionary<Component, Pool>. Then you dont need to search for an ID cause its just
objectPools[GameObjectThatIWant].

[latent latch]

ye should just stick to a specific type for each pool

[lean sail]

Also its the same like how you are using a string for the ID, you could remove that string entirely and just compare the prefab

[latent latch]

Pool<T>
public T prefab;

[mighty juniper]

Gotcha, working on implementing it now

[latent latch]

It's more that GameObject itself is pretty ambiguous, even if you know what's to be stored in it. Usually you want pools to be quick and direct at what they're distributing.

[vagrant blade]

Finer control. But if you're new, a rigidbody is "easier" to move, you just point and launch it.

[rigid island]

you can have more control over cc without worrying too much about collision detection

kinematic can give you control as much but then you need your own detections for wall

[twilit scaffold]

Anyone know why childRectTransformMaximumSize; is a different color than the rest? It is used shortly after this declaration

Bah. It is never actually used, even though a value is assigned in Start. i forgot i changed that calculation

[rigid island]

yeah assigning a value doesn't necessarily mean its being used

[sleek heath]

CharacterController has other little goodies which rigidbody doesn't have

cc is good for if you want a player controller that does everything you want out of the box
