How to Set Input

To set Active Input Handling, go to:
Project Settings > Player > Active Input Handling

• Input Manager (Old): Use the original Input settings.
• Input System Package (New): Uses the new input system package.
• Both: Use both systems.

sorry if this is a wrong channel to ask this, but i need advice
i tried making multiple versions of a character controller for a 2D game that has moving as fast as possible as the main concept and the approach that felt the best was using transform.position += though i saw some people say that a rigid body would be better so i'm wondering if switching to it would really be worth it (despite the issues i had with it like movement on ground vs in air)

[rich adder]

that really depends.. you can easily detect collisions also with just transform if you use rays.
how fast is it moving ? rigidbody can feel clunky if they are not tuned properly thats why most controllers are kinematic

[swift crag]

If other physics objects should be able to hit the player and move them around (not just block them!), then you want a rigidbody

[polar acorn]

Put it on the asset store and post it in #1179447338188673034

[rich adder]

(urgent, today)
sounds sus

[stark drift]

how about if the only objects that physically interact with the player are walls and moving platforms?

[umbral hull]

hey im not rlly sure how beginner this is, but here's my problem:
im making uno (just as a personal project) and im trying to figure out how to assign the card sprites to the card values so that the correct sprites show on the screen. i already have the hands populated with cards i just am unsure how to go about my problem

[upbeat pasture]

Scriptable objects perhaps?

[rich adder]

I would also go with SOs

[upbeat pasture]

With scriptable objects you can create an object with a color, pickup quantity etc

They will also allow you to store the card images

[umbral hull]

hm, ill look into this, thanks... but does that mean i will have to change all my object types?

They will also allow you to store the card images
yeah i saw this when i looked it up, p nice for my problem

right now i have my cards stored as a custom Card class

[upbeat pasture]

perhaps, I don't use them very often, but their essentially just a container

[upbeat pasture]

Yeah, so imagine your Card class, except you can create the cards before you press play, they will most likely have the same data

[umbral hull]

how did you do that so fast?? anyways...

[rich adder]

haha UNO is a great project to do. Made this years ago

[umbral hull]

ah i see

[umbral hull]

but yeah ill look into that, seems very useful in general, thanks

[untold crypt]

hey all 👋 just joined
backend/devops guy here, also messing around with automation tools and indie projects
excited to see what everyone’s working on

[rich adder]

basically they are tangible classes / object you can manipulate in the project / editor at edit time instead of runtime.
btw each one was created with a script with values assigned, just so you don't think you have to manually do each scriptableobject assigning enums manually all cards lol

[upbeat pasture]

CameraManager singleton? Or direct inspector reference to Camera?

I feel like Im falling into a common pitfall with the singletons

[rich adder]

depends what needs it

simple DI goes a long way, not everything needs a singleton / manager

[upbeat pasture]

I have movement and camera logic split for single responsibility, character controller needs access to Camera transform to rotate the player transform to the Cameras current Y.

[rich adder]

[upbeat pasture]

I am most likely going to need a hard reference to camera for camera shake etc though, and I assumed the singleton would be better than 100 inspector references maybe.

Ive read a LOT of negative press about the singleton pattern though

[rich adder]

its easy to abuse but they are not bad at all and pretty common pattern outside of unity

[rich adder]

why do 100 things need camera reference?

[upbeat pasture]

Lets say I fire a missile at the player and it misses them, hitting the floor in front of them. I call CameraShaker ShakeCamrea(), CameraShaker needs reference to the camera

PlayerMovement also needs reference to the camera, for rotating the character

Maybe theres a cutscene system, that will also now need reference to the camera

[rich adder]

the missle should only say " I hit something" then you can use events to fire a camera shake

[umbral hull]

so when would i use instantiate vs Scriptable Objects? or would i use them together? like ik instantiate is for when i want to spawn alot of the smae enemies in a plaformer or something. i used it once when i had to make a drivable tank for class.

[rich adder]

thats only 1 script tho

[upbeat pasture]

UnityEvents? Dont those need to be linked up to work?

[rich adder]

its not a Instantiate VS SOs thing.
they can work together, they are just not gameobjects so they are not spawned

they live within another object, like an asset.. think audio asset, a sprite asset etc

[umbral hull]

yeah, instantiate was just one of solutions i was looking at so i was just curious about the question in general

[rich adder]

they are basically templates of data you can use

[swift crag]

you're describing an apples-and-oranges comparison here

to "instantiate" is to copy a Unity object

ScriptableObjects are, indeed, a kind of Unity object

as are GameObjects, Materials, etc.

[rich adder]

you spawn something,
the ShakeScreen manager or whatever Subscribes to events like the spawned objects event "HIT Something"
then spawned object fires that event on hit something,
ShakeScreen reacts to it with Shaking the Screen function

[umbral hull]

oooh bc instantiate creates the object in the hierarchy, but that wouldnt create the visual effect

[rich adder]

create the visual effect ?

you got lost somewhere here..

[umbral hull]

oh i didnt see the response and i got confused

nav replying to bamma

[rich adder]

oh

[upbeat pasture]

I think how it works is, you load the SO into a monobehaviour, the monobehaviour reads the data inside the SO, and does stuff with it.

For example, blank card monobehaviour gets the IMG from the scriptable object, and updates its card image property

[rich adder]

if your sprites have predefined color/number already then SOs were mentioned to assign sprite to specific value/color

like I shown in SS

[grand snow]

MVC time

Card view to show a card, card data/model to hold the data

[swift crag]

notably, this means that the card that your gameplay systems card about may not be a Unity object at all

[cosmic dagger]

I agree, it can be a helpful tool for explaining code or on how to expand it. I was touching on why we steer newbies away from it (until they learn the fundamentals) bcuz sadly, they don't do any of what you mentioned

It is a separate issue, but they lean on the LLM too much as an aide . . .

[cosmic dagger]

Wow, that is a good idea . . .

[upbeat pasture]

MVC is so cool

[rich adder]

needed a card game without getting too complex and easy to pickup for others lol

who doesn't love uno tho

[upbeat pasture]

another really really good starter project I personally suggest is boids

boids are so cool

[cosmic dagger]

Oh, I meant YouTube for the C# fundamentals. That's usually the same across the board (give or take a few topics)

Some may have more than oyhers, but you can get a lot of the basics from websites . . .

[cosmic dagger]

Facts, I have Uno Attack. I should consider attempting to build it . . .

[grand snow]

Sometimes some good old software design is needed

[rich adder]

C# vids in Unity Context..mostly crap
C# vids in general C# context are the decent ones

[grand snow]

Too much game jank suggested here

[cosmic dagger]

@upbeat pasture I may have implemented MVC without knowing, but I can't say I've properly/knowingly tried the pattern. Is that the same or similar to MVVM?

[grand snow]

Id say so yes. I like the patterns as they teach you how to have logic and state separate from UI/visual view

[cosmic dagger]

I've never done programming outside of Unity, so I figured these patterns are more C# software development or Web Dev stuff (I think ) . . .

[upbeat pasture]

pretty sure MVVM is just controlling logic in the view right?

MVC MVP MVVM are pretty much all the same

They just all reference eachother differently

Like the MVP is basically jus the MVC but it references the model less?? If I remember correctly.

[rich adder]

WPF flashbacks 😵‍💫

[upbeat pasture]

There are too many architecture acronyms

I like the PISS architecture personally

[grand snow]

SOLID would like a word too

[swift crag]

what's the architecture where you just make the game

i can't tell if i'm joking or not right now

[upbeat pasture]

When I started studying software arch I followed SOLID 100%, and it was just a headache

[swift crag]

SOLID is a nice platonic ideal

[cosmic dagger]

I usually stick to KISS and SOLID . . .

[rich adder]

learned most patterns through WPF (windows presentation form) and it was def not fun but It def speeds up a lot of knowledge

[naive pawn]

can't seem to find what PISS is supposed to be...

[upbeat pasture]

SOLID is a good idea until everything is abstracted and everything is also a subclass of a class

[naive pawn]

to be pedantic though these are principles not architectures

DRY's another one

though DRY is pretty good to follow

[umbral hull]

what is MVC? I keep thinking marvel vs capcom lol

[naive pawn]

model-view-controller

[grand snow]

I wouldn't do all of solid but it's ideas are good

[upbeat pasture]

thats rough man

[rich adder]

as Barbossa says, more like "guidelines"

[naive pawn]

should be able to google it though

[cosmic dagger]

I feel like there's a multi-player game with these acronyms as teams in the making

Each team solves the problem using their set of rules . . .

[naive pawn]

architecture is, like many things, better described with pasta shapes

just like nuclear pasta

[umbral hull]

theres so many ways to shave a cat

[upbeat pasture]

You dont really need to worry about it in unity

[rich adder]

not entirely accurate

[upbeat pasture]

Its more if you are making apps

[rich adder]

https://learn.unity.com/course/design-patterns-unity-6/tutorial/build-a-modular-codebase-with-mvc-and-mvp-programming-patterns

[cosmic dagger]

KISS vs SOLID vs DRY vs MVC/P/VM

Two groups are principles that utilize a bunch of different architectural approaches while the other two are specific architecture workflows . . .

[upbeat pasture]

Im just imagining all of my variables in the model

Even if they dont really belong there

[naive pawn]

isn't SOLID a group of principles rather than an architecture?

[cosmic dagger]

Oh, I don't like bloat . . .

[naive pawn]

damn i only remember SRP and Liskov substitution lmao

[cosmic dagger]

I guess that's more true, but some of the principles use a specific architecture and or pattern . . .

Isn't one of them injection or dependency or smth?

[naive pawn]

i don't remember the other 3, i should go check...

[swift crag]

the "Liskov substitution principle" is just the idea that you can freely substitute B for A if B is a kind of A

[upbeat pasture]

Dependancy injection and single responsibility are the only two good ones to follow

and liskov

[swift crag]

i.e. you shouldn't have derived types that fail in situations where the parent type does not

for example

if you have an Enemy class that has a Move method, you can't add a FlyingEnemy class whose Move method throws an exception if the enemy is on the ground

[naive pawn]

isn't it the inverse

ah wait i misread

[swift crag]

you've strengthened a precondition here!

which means that the user of the object suddenly has extra rules to obey

[naive pawn]

Single responsibility principle - there should never be more than one reason for a class to change. In other words, every class should have only one responsibility.
Open–closed principle - software entities should be open for extension, but closed for modification.
Liskov substitution principle - functions that use pointers or references to base classes must be able to use pointers or references of derived classes without knowing it.
Interface segregation principle - clients should not be forced to depend upon interface methods that they do not use.
Dependency inversion principle - depend upon abstractions, not concretes.
-# from Wikipedia: SOLID

Game Actually Exists 😉

[upbeat pasture]

I do not vibe with open closed

[dull slate]

Is learning more efficient through hands-on experimentation with small projects and looking things up as needed, or are structured courses like GameDev.tv more important for building a strong foundation?

[solar hill]

i have no clue what gamedev.tv is but if you want to learn youre best off following the official unity learning pathways

Heavily depends on the person. I had to go around trying out stuff to see what worked with me the best. Personally, I lacked fundamentals to understand programming, and making small projects for game jams made me feel quite lost, even as I was learning.

[midnight jolt]

Hi, could someone explain to me why this doesn't want to work? What I'm trying to do is rotate the player to wherever their cursor is at

Vector3 screenToWorld = Camera.main.ScreenToWorldPoint(Input.mousePositionDelta);

transform.rotation = new Quaternion(0, screenToWorld.y, 0, 0);```

sorry for the snippet, but not sure if code this short is worth posting on pastebin

[frail hawk]

is that for 2d

[rich adder]

you're trying to pass world positionY to a quaternion 🤔 doesn't make much sense thats why it doesn't work

quaternions values max out at 1 so they are not values you typically mess with without using the Quaternion functions like Quaternion.Euler

[midnight jolt]

ohh

[rich adder]

the basic gist, get the direction from your start point in world, to your worldPoint
get the direction. Pass that to the transform forward or rotation, something quaternion.lookRotation

or if 2D you can use that direction w Atan / Rad2Deg and, .rotation = Quaternin.Euler(0,0,angle)

[midnight jolt]

3D

Okay I see

[rich adder]

so yeah Quaternion is not Euler angles

[frail hawk]

if it is for 3d you dont need to convert mouse to screenworldppoint

you need the mouse axis

[rich adder]

if they want the position of the cursor the they do

depends what they're making

[frail hawk]

we´d need more context

[midnight jolt]

right now i'm just trying to make the character walk and look around. I've got it to walk, now I'm having difficulties with the rotation

[rich adder]

if its like FPV thing then you don't need ScreenToWorld

look at the many examples on how other people do the camera

In most cases you're not looking at specific point through mouse pos, you're rotating the player/camera itself to look at specific point

[midnight jolt]

I see

it's just I really tried to do this alone y'know

to learn

but thanks

[rich adder]

once you get base knowledge especially all the components these are easier to build than they seem

[naive pawn]

(basically what nav was saying but explicitly) don't use new Quaternion, don't use rotation.x/y/z, they aren't values that would be intuitive to you unless you're a mathematician

    {
        coyoteTimeCounter = coyoteTime;
        jumpsRemaining = maxJumps;
    }
    else
    {
        coyoteTimeCounter -= Time.deltaTime;
    }

    // Movement
    if (!isDashing)
        rb.linearVelocity = new Vector2(moveInput * moveSpeed, rb.linearVelocity.y);

    // Jump
    if (Input.GetKeyDown(KeyCode.Space) && (coyoteTimeCounter > 0f || jumpsRemaining > 0))
    {
        rb.linearVelocity = new Vector2(rb.linearVelocity.x, jumpForce);
        jumpsRemaining--;
        coyoteTimeCounter = 0f;
    }

    // Dash
    if (Input.GetKeyDown(KeyCode.LeftShift) && !isDashing)
        StartDash();

    // Flip
    if (moveInput != 0 && !isDashing)
        sr.flipX = moveInput < 0;
}

{
    isDashing = true;
    float dashDirection = sr.flipX ? -1f : 1f;
    rb.linearVelocity = new Vector2(dashDirection * dashForce, 0f);
    Invoke(nameof(EndDash), 0.18f);
}

void EndDash() => isDashing = false;

Hey guys

[still ingot]

Hey I'm doing something a little out of my comfort zone and trying to make a ledge climb mechanic for my game. I'm trying to make it precise by calculating the distance between the hit point and the height of the actual mesh/ledge. This is my code currently, the player when the ledge detector ray hits a gameObject with the layer Ledge a second ray will spawn from the hit point of the first ray. I was trying to have it go up (Y+) by using transform.up. Instead I have the screen shot shown. I used more visible colors to make it easier to see in the screen shot

**

• Raycast From LedgeChecker gameObject (Blue)
• Normal Surface/Hit Point Second RayCast (Red)
  **

    private void OnDrawGizmos()
    {
        //Main Ray Detector
        Gizmos.DrawRay(ledgeCheckerStart.position, orientation.forward * checkDistance);

        //Normal Y Ray along Ledge Surface
        float distance = (val.normal.y - val.point.y);
        Gizmos.DrawRay(val.point, transform.up * distance);
    }

    private void FixedUpdate()
    {
        LedgeDetector();
    }

    private void LedgeDetector()
    {
        //Check for mesh with Ledge layer
        isLedge = Physics.Raycast(ledgeCheckerStart.position, orientation.forward,out RaycastHit hit, checkDistance, whatIsLedge);
        val = hit;

        if (isLedge)
        {
            var obj = hit.collider.gameObject;
            canHang = true;
        }
        else
        {
            canHang = false;
        }

        //Check find the distance between the hit point of first ray to the height of mesh to snap the player to that location
        if (canHang)
        {
            float distance = (transform.position.y - val.point.y);

            if (Physics.Raycast(val.point, transform.up, out RaycastHit surfaceHit, distance))
            {
                Debug.Log("HIT ALONG SURFACE");
            }
            else
            {
                Debug.Log("SPAWNED LINE ALONG SURFACE");
            }
        }
    }

[still ingot]

How can I make a raycast that is shown in the up direction instead of checking everything below?

[frosty hound]

Raycasts point in the direction you give it, they don't "default" to pointing "below".

So whatever direction you're applying, point it up. If you want it straight up regardless of rotation, use Vector3.up

[still ingot]

The ray is still going down instead of up?

        //Normal Y Ray along Ledge Surface
        float distance = (Vector3.up - val.point).y;
        Gizmos.DrawRay(val.point, Vector3.up * distance);

        //Check find the distance between the hit point of first ray to the height of mesh to snap the player to that location
        if (canHang)
        {
            float distance = (Vector3.up - val.point).y;

            if (Physics.Raycast(val.point, Vector3.up, out RaycastHit surfaceHit, distance))
            {
                Debug.Log("HIT ALONG SURFACE");
            }
            else
            {
                Debug.Log("SPAWNED LINE ALONG SURFACE");
            }
        }

[rich adder]

whats the value of distance cause if its negative you're doing * - which will flip it

since Raycast is only Vector3.up if you pullup the Physics Debugger you should see which direction raycast is going

[gusty folio]

im trying to parent the player to a moving platform so that the player can move with it but for some reason the player doesnt move with said platform. is it because rigidbodies arent fully compatible with parenting?

or maybe its just how i coded the platforms

[rich adder]

unless kinematic , with dynamic rigidbody it wont work , when on platform you need to add the platform speed to the player velocity

[gusty folio]

im getting this weird bouncing behavior for vertical moving platforms. should i just add horizontal velocity then?

[eager stratus]

I'm trying to set a rigidbody's linear velocity inside a coroutine what I assumed would be every physics update (in this case theoretically making it so it travels forward indefinitely), but it's not moving what so ever. Why?

{
    //For the time being just set it to continuously push it back
    while (true)
    {
        print("Should be knocking " + name + " back");
        GetComponent<Rigidbody>().linearVelocity = Vector3.forward;
        yield return new WaitForFixedUpdate();
    }
}```

[naive pawn]

is the rigidbody dynamic or kinematic?

[eager stratus]

It's definitely not kinematic

This is what the Rigidbody looks like at runtime and none of these values ever change

[naive pawn]

make sure the object isn't excessively big (since in that case moving 1 unit per second would be very small)

also make sure you've actually started the coroutine

[eager stratus]

The object is just a standard sized capsule collider

[eager stratus]

The debug message in the coroutine is playing, so the coroutine is definitely playing too

[naive pawn]

is the debug message printing continuously?

[eager stratus]

If I have it print the linear velocity before the yield return it gives me the right vector, but if I do it after the yield return then the vector resets to Vector3.zero (Very rarely it'll be the right vector, but it's very rare)

[eager stratus]

Yes

[naive pawn]

do you perhaps have anything else setting the linearVelocity?

[eager stratus]

Not for this object. This is the only script on it

...Wait

I think I know what the problem might be now

Ok. That fixed it

The animator was set to apply root motion

Unchecking it allowed the physics engine to actually affect it

[echo ruin]

Anyone knows why I get this error whenever I try to write a coroutine?
https://puu.sh/KNtJp/f8a88343ff.png

It fixes itself if I just copy/paste the word IEnumerator for whatever reason.

Still somewhat annoying

[verbal dome]

Iirc you need using System.Collections;

Currently it thinks you are trying to use the generic IEnumerator<T> from System.Collections.Generic

[echo ruin]

That does make a lot of sense

[half lily]

Hello ! I'm very new and I ran into this problem that I can't figure out :

I have an "Bar" in my HealthBar that I try to scale every frame between 0 and 1 with the healthPercent. Unfortunely, it doesnt update at all. The script works because when I input values manually, it displays the right ratio on load, but it doesnt update when unit takes damage. I dont know what I'm doing wrong.

[keen dew]

You're updating the prefab, not the instantiated object

It needs to be something like this:

private HealthBar healthBar;
...
healthBar = Instantiate(...)
...
healthBar.SetSize(...)

[frail hawk]

also transform.Find("Bar") doest make any sense there , if you wanted to reference the bar GameObject you could simply use the inspector

[half lily]

Thank you to the both of you! I managed to make it work :)

Guys how can I do:

A random objekt spawn only on x = -2 or 0 or 2

** My Idea was to make a random number from 1 to 3 ,
1 = -2 , 2 = 0, 3 = -2 ** is that right?

[swift crag]

That will work, yes.

[dry pulsar]

kk but is there any "better" way

[swift crag]

If you want to be able to configure the positions in the inspector, you could pick a random value from an array

[dry pulsar]

So make an array and give every slot like a position?

[swift crag]

public List<float> positions;

then, elsewhere:

positions[Random.Range(0, positions.Count)];

this will give you a random value from that array

[dry pulsar]

kk ty

[naive pawn]

consider what they mean in your situation.
if they're choices, use a list and index them

if they're dynamic values that you happen to have spaced 2 apart, consider using math to modify the range, eg you could do Random.Range(0, 3) * 2 - 2
(you can still configure this from the inspector with 3 slots - amount of values, spacing, first value)

[still ingot]

Does anyone know how to calculate and find the remaining height of a cube from the raycast hit point. Im making a simple ledge grab mechanic?

I tried just turning off the gravity when colliding but then that messed up my player controller so I need to actually use raycast haha

[dry pulsar]

@swift crag @naive pawn is this okay too´?

[naive pawn]

would recommend using something like coroutines rather than InvokeRepeating, but yeah sure

[dry pulsar]

Havent learned that yet

[blazing horizon]

okay so, why does this

_rigidbody.AddForce(Vector3.up * 30);

randomly either do nothing or launch my object stupidly far in an instant

object in question

[swift crag]

how are you running that code? in Update?

[blazing horizon]

it checks for key press in update

oh it seems that rubbing against cubes can also sometimes cause that

(I move the thing by setting linearVelocity)

[swift crag]

if you set the velocity, the old velocity will be lost

applying a force causes the velocity to change

[blazing horizon]

I keep the Y value during the setting and I also do horizontal movement before jump handling

okay, this is all kind of wacky

it seems that the object just fails to zero out its y velocity upon touching ground

so it stays on ground, but if I teleport it to y 60 it falls back in an instant

[naive pawn]

so you want this to be instantaneous?

in that case you'd pass a ForceMode of either Impulse or VelocityChange

[naive pawn]

are you applying gravity manually or something?

[blazing horizon]

not really

and I don't suppose a gravity force of 30 is enough to break the engine

[swift crag]

we'll need to see your code

[blazing horizon]

using UnityEngine;
using UnityEngine.InputSystem;

public class Player : MonoBehaviour
{
    public static Player Instance;

    private Rigidbody _rigidbody;
    private InputAction _moveAction;
    private InputAction _jumpAction;

    void Awake()
    {
        if(Instance!=null) Destroy(gameObject);
        Instance = this;
        _rigidbody = GetComponent<Rigidbody>();
        _moveAction = InputSystem.actions.FindAction("Move");
        _jumpAction = InputSystem.actions.FindAction("Jump");
        _rigidbody.maxLinearVelocity = 10;
    }

    void Update()
    {
        ReactToMove();
        HandleJump();
    }

    public void ReactToMove()
    {
        Vector2 m = _moveAction.ReadValue<Vector2>();
        _rigidbody.linearVelocity = Quaternion.AngleAxis(CameraController.Instance.transform.localEulerAngles.y, Vector3.up) 
            * new Vector3(m.x, _rigidbody.linearVelocity.y, m.y) * 10;
    }

    private void HandleJump()
    {
        if(_jumpAction.WasPressedThisFrame())
        {
            _rigidbody.AddForce(Vector3.up * 30, ForceMode.Impulse);
        }
    }
}

after adding the velocity limit it would seem that the object maxes out on vertical velocity and doesn't decelerate

[cosmic quail]

you're multiplying it's linearvelocity's y by 10 each frame?

[blazing horizon]

💀

lmao, okay, thanks

sneaked right past me

[rich adder]

couple of things. Physics movement should ideally be done in FixedUpdate.
(ForceMode.Impulse is fine in Update since its a once frame event)
Try to avoid Magic numbers like * 30
use variables like * jumpForce etc.
also they can be easily changed in inspector at runtime for tuning

[blazing horizon]

oh I know, I'm just throwing a quick prototype, all of this is up for cleanup

[hard fossil]

If you just want the variables to be exposed in the inspector use [SerializeField] and make them private. Public should only be used when other scripts want to see the variable.

[still ingot]

Here is a better visual representation of what I am trying to do. I'm trying to get the distance between the hit point and the top of the ledge height?

[rich adder]

you probably need to query the collider upper half values

[hard fossil]

YPosition of Object + Half it's Y size is the position of the top. So just subtract the hit point Y from that.

[rich adder]

caveat.. not all pivots start from middle, and scale on gameobject is a scalar so not accurate sizing,
collider will give you decent size values to work with

[hard fossil]

I'm just going off the diagram, he has the pivot at the center, and when I say size, what I should say is distance incase it's scaled as you say.

[rich adder]

mhm
frankly if I were OP and this is a climb type mechanic I would do multiple queries.
1-2 to get get climbable wall, then check if it has at the top enough space for me to fit, so maybe do an overlap from there

something like this

[still ingot]

This is the project I made a gif to show what is happening

I have 3 raycast and I'm trying to make sphere cast at each point so its easier for others to see the ledge detectors

The ray going upward is too long I need to calculate the hit point and the ledge height to make it precise

[rich adder]

why do you need a ray going up anyway

[still ingot]

Yes this will be climbable!

[rich adder]

once you find the "ground" of the thing you want to climb, I would just do what I suggested. Check if the player can fit if he climbs, through the overlap cast

this avoids you trying to climb something that may have a low ceiling

[still ingot]

By having a ray going upward from the hit point I can get the exact shape around the cube to find the top surface of the cube where our hands would go

That's why Im also making wire spheres to better keep track of everything

The red ray should stop when it goes above the surface of the ledge so that does need to be fixed

[rich adder]

a hack way you can shoot another ray down to find the floor

[still ingot]

From the player or the red raycast?

[rich adder]

once the red ray moves up, as soon as it finds the ground(with ray shooting down from its end pos) it could perhaps move up until there is enough clearance for the player to climb

but you can also find the floor / part you need by querying the collider top part

there are also things like https://docs.unity3d.com/ScriptReference/Collider.Raycast.html

[languid pagoda]

https://streamable.com/3za7rk

how would I go about keeping them from clumping up? adding a navmeshobstacle to each zombie just makes them trip out.

[rich adder]

you need to start by separating their destination
vary their move speeds
vary their priority

they're all trying to move to a single point it makes it jank
I use multiple targets around the player, it keeps them from bunching up

most times if they are melee players, they try to encircle the player too..
this keeps it from being boring looking one direction for them

[languid pagoda]

I currently am using Random.InsideUnitCircle so they all get a random point around the player, maybe I need to increase the circle size. Good idea on varying speeds and priority. I think that will help a lot.

[rich adder]

yeah thats a good start. You also do some tricks where not all of them will go exactly where player is at first, depending ofc how "intelligent" you want them to appear. Also idk your game design but try not to make them spawn from the same spot / direction .. vary some where if player moves away not all of them start chasing player or at least not right away.
some randomness goes a long way

use verticality if your design allows, zombies that can also climb down / jump down to you or crawl from small floor spaces will add some spice

[still ingot]

    private Vector3 CalculateLedgeHeight(RaycastHit ledgeRay)
    {
        //Place holder variable
        Vector3 ledgeHeight = Vector3.zero;

        //Find the distance between the raycast hit point and the rest of the ledge height on the y leading to the top
        float distance = ledgeRay.point.y - ledgeCollider.bounds.center.y; //???? Is this the right track



        return ledgeHeight;
    }

[languid pagoda]

Thank you for all of the good ideas!

[hard fossil]

You're reversing the subtraction, and not taking into consideration the half height of the ledge object. It should be ledge Y center position + half Y height of ledge object (which will give you the y position of the top of the ledge), then subtract the ray Y position, so you get the distance between the top of the ledge and the ray.

[still ingot]

    private float CalculateLedgeHeight(RaycastHit ledgeRay)
    {
        //Represents y distance between raycast hit and top of ledge
        float ledgeHeight = 0f;

        //Calculate the position of the top ledge
        //It should be ledge Y center position + half Y height  of ledge object (which will give you the y position of the top of the ledge)
        float ledgeYDistance = ledgeRay.point.y + (ledgeCollider.bounds.center.y/2) ;

        //Get the difference (distance in between)
        ledgeHeight = (ledgeYDistance - ledgeRay.point.y);

        Debug.DrawRay(ledgeRay.point, Vector3.up * ledgeHeight, Color.red);

        //Create A Raycast to find the top of the surface
        if(!Physics.Raycast(ledgeRay.point, Vector3.up, out RaycastHit hit, ledgeHeight))
        {

        }

        return ledgeHeight;
    }

I get the feeling I might be close but there is something I'm missing to make it the right height

[still ingot]

//Get the difference (distance in between) ledgeHeight = (ledgeYDistance - ledgeRay.point.y) - step;

[rich adder]

can't you do something like this?

   var raycastHit = Physics.Raycast(
            transform.position,
            transform.forward,
             out var rayHitInfo,
            1.2f
        );

        if (!raycastHit) return;
        hitRay = rayHitInfo.point;

        topCollider = rayHitInfo.point;
        topCollider.y = rayHitInfo.collider.bounds.max.y;

        var startTopPos = topCollider + Vector3.up * charHeight;
        var someOffsetFromEdge = 0.12f;
        var frontHitPosIn = -rayHitInfo.normal * someOffsetFromEdge;
        startPos = startTopPos + frontHitPosIn;

        var colRay = new Ray(startPos, Vector3.down);
        var hitCollider = rayHitInfo.collider.Raycast(
            colRay,
            out var colRay_HitInfo,
            3f
            );

        if (!hitCollider) return;

        // the spot where we want to climb probably?
        //colRay_HitInfo.point```
its kinda hack but might work
you can fix magic numbers tho

I used something like this in the past, but the requirements weren't too strict, and was dealing with easy primitives

@still ingot

there is probably a simpler way but my brain today aint havin it lol maybe someone else has a cleaner more mathy way

[still ingot]

Not gonna lie this looks cool. Like your in animal crossing placing down furniture haha.

[rich adder]

gizmos r fun

[still ingot]

This works a lot better for checking the height of the ledge from the hit point!

[rich adder]

k.i.s.s. principle at its best lol

[hard fossil]

You have a mistake in the code here. float ledgeYDistance = ledgeRay.point.y << (this should be ledge object position.y)

[rich adder]

which one

[hard fossil]

Did you fix the mistake?

[still ingot]

I actually used @nav example added a debug ray from the top ledge corner!

    private float CalculateLedgeHeight(RaycastHit ledgeRay)
    {
        //Represents y distance between raycast hit and top of ledge
        float ledgeHeight = 0f;

        //Get the top height of the mesh
        Vector3 topCollider = ledgeRay.point;
        topCollider.y = ledgeRay.collider.bounds.max.y;

        //Top point Y of the mesh
        var startTopPos = topCollider + Vector3.up * ledgeHeight;
        val2 = startTopPos;
        Debug.DrawRay(startTopPos, Vector3.up * -0.1f, Color.red);

        //Disable wiresphere
        if (!isLedge)
            val2 = Vector3.zero;

        //Create a forward Raycast
        if (!Physics.Raycast(startTopPos, Vector3.up, out RaycastHit hit, -0.3f))
        {
            Debug.DrawRay(startTopPos, orientation.forward * 0.1f, Color.red);
        }

        return ledgeHeight;
    }

I think the fact that I wasn't really getting the colliders bounds was the reason why it was difficult

[hard fossil]

float ledgeYDistance = ledgeRay.point.y + (ledgeCollider.bounds.center.y/2) ;

    //Get the difference (distance in between)
    ledgeHeight = (ledgeYDistance - ledgeRay.point.y);

If you look at that too, you'll see that you're adding and subtracting ledgeRay.point.y, so that will cancel to 0, so the ledge height will always be (ledgeCollider.bounds.center.y/2)

[still ingot]

I added more on to the function which snaps the player to the hanging location. I tried adding offsets to help keep the player from merging into the ledge:

        ///////HANG ON LEDGE AT LOCATION BELOW///////

        //Create a forward Raycast
        if (!Physics.Raycast(startTopPos, Vector3.up, out RaycastHit hit, -0.3f))
        {
            Debug.DrawRay(startTopPos, orientation.forward * 0.1f, Color.red);
            isHanging = true;
        }
       
        Vector3 hangLocation = new Vector3(startTopPos.x, startTopPos.y + offsetY, startTopPos.z + offsetZ);

        if (isHanging)
        {
            transform.position = hangLocation;
            rb.useGravity = false;
            playerObject.enabled = false;
        }

like... its actually not working, even debugging with Update does absolutely nothing

script is monobehavior, everything was added into the object

Try making a new script and testing that out with debug logs

Then if it works port over the code from the original to test again to be sure its not your code as well

https://pastes.dev/ikynHgvNi5 trying to add a limit but it freezes my unity instead

[naive pawn]

the while there will keep looping within the same frame

since transform.position isn't changing, this will be an infinite loop

keep in mind that Update is already a loop that executes once per frame. you may want an if instead of the while, or consider using coroutines

also the first condition in the while is covered by the second one

[frail hawk]

the condition is really weird

are you looking for something between -2 and -7 maybe?

[cosmic sable]

adding limits at -2 and -7

[naive pawn]

if you want it to be between those values, you would need <= -2

[frail hawk]

i guess you want || then if you want -2 or -7

Hello, i want to install the webgl module for unity 6000.3.6f1 and then build, why i dont see an option to install here?

[cunning estuary]

hey im not an good coder

how do i make this goal spin around the circle but make it stay in the middle of the line? please help me out

[keen dew]

Put the goal's pivot point in the middle of the circle and then rotate normally

[cunning estuary]

ok wiat

im a bit new to unity'

[keen dew]

alternatively rotateAround the middle of the circle

[cunning estuary]

let me tryt

[muted sand]

this might be a dumb question, but i'd assume that running new some_class() 100x in a single script is a significantly less strain on the computer than having the script class being put on 100 different objects?

[keen dew]

It's unlikely that there's any measurable difference. The choice should be based primarily on other things than performance

[cunning estuary]

.. this

[keen dew]

If it does that then either the pivot point is wrong or the code that rotates it is wrong

[cunning estuary]

ok

let me try

is therre any other wayt

is ther any other way to make it spin like how i want it

[rich adder]

they told you how

[keen dew]

It's done the same way no matter if you're very new or if you have 20 years of experience

put the goal as child of the circle, move it to the edge where it needs to be, rotate the parent circle

What's the workaround?

[still ingot]

Here is the code I added for my ledge climb script. Now the weird thing that's obvious in the clip I shared is the player will be shifted based on the offset that's great, but its not what I want. I want the players forward location to be offset by the ledge its facing. Also is it possible that I need to make the player a child of the ledge?

        Vector3 hangLocation = new Vector3(startTopPos.x + offsetX, startTopPos.y + offsetY, startTopPos.z + offsetZ);

        

        if (isHanging)
        {
            transform.position = hangLocation;
            rb.useGravity = false;

To some extent you just slowly pick these up but searching something like "unity limiting value between min or max" or etc. would probably lead you here

[nocturne carbon]

i ran into a problem yesterday where when i added a network object and network transform to my character controller in unity that when it jumps it will jump forever, like it never detected leaving the ground and was caught in a loop, i have a cloth sim for his jacket - just wondering if it thinks the ground is the cloth colliders for his legs? Just using the third person controller asset

[hard fossil]

Without seeing code, we can't see how it works.

[nocturne carbon]

it was the thirdperson controller from the starter asset - i dont think I'm allowed to share it

[hard fossil]

You can show the code.

[nocturne carbon]

i think i fixed it, i think it had something to do with the way i reordered the prefab and had some hidden duplicate controller or something wierd, thanks anyway

[primal rampart]

guys if i just want the mesh collider to work properly i should always make it convex right.

[night raptor]

Yes and no. If you want it to be dynamic, it must be convex. For static colliders (no active rigidbody), non-convex is totally fine

[primal rampart]

hmm k , also is it possible for me to view the mesh collider?

[night raptor]

With the Physics Debugger I believe so. Outside of that, I'm not aware of a way

I guess Unity thought the mesh would usually just reflect the rendered mesh so there wouldn't be a point in visualizing it

[primal rampart]

yeah but since there is a diff between a concave and a convex mesh , should visualizing it be helpful on what to choose in certain scenarios

[night raptor]

How would it be helpful though? You see the mesh no? Unless you are using a different mesh for rendering and for the collider...

[primal rampart]

and its on btw , but i can't see mesh colliders, i can see the other normal collideres like box or capsule

[primal rampart]

ok so ig i should assume that convex collider doesnt consider holes and other stuff, else it fully fills the material

[cunning burrow]

hi

i have a question what tutorial should i watch on youtube? iam complete beginner in c# scripting

[night raptor]

oh wait are you not seeing convex colliders either? Normally you would not see concave mesh colliders but convex would show like other colliders

[primal rampart]

yeah exactly lol

[primal rampart]

for c sharp??

[cunning burrow]

yes

[primal rampart]

well you can find some all in one basics video and understand how C sharp works. Tbh that is enough.

[cunning burrow]

oh alright thank you for replying

[night raptor]

Do you have MeshColliders disabled from here?

[primal rampart]

one sec lemme check

[primal rampart]

ok where is that ???

[night raptor]

On the scene view, top right maybe if you haven't moved it?

You need to have the view options enabled though for it to be visible

[primal rampart]

it was at the bottom for me .

[naive pawn]

there are resources pinned in this channel

[cunning burrow]

i just found good tutorial i think

can i send link here

[naive pawn]

for what purpose, exactly..?

[cunning burrow]

to show if is it good

[night raptor]

But do you have mesh colliders visible on the gizmos visibility view?

[naive pawn]

well no-one's stopping you but you aren't necessarily going to get answers about pros or cons

[cunning burrow]

oh ok

ill just watch the tut

[orchid trout]

sort of outside of unity but does anyone know why visual studio sometimes just won't find code that clearly exists? Here it is not finding the exact string im staring at

What are you even trying to search for? Post a screenshot which has the the whole search window

[primal rampart]

is that in the game view?

[orchid trout]

Oh sorry, the error message has the string I was searching for in it, I was searching under "entire sollution" because none of the options yielded any results despite me knowing that exact string exists

this was yesterday so I dont have VS open in front of me now

in this excercise im trying to do from "learnunity.com" , the top plane and the cylinders get thrown upwards when i start the game. Everything but the bottom plane has rigid body and all of the meshes have a mesh collider. Why is this the case bruh.

[night raptor]

Can you show the Physics Debugger?

[primal rampart]

k one sec

anything specific?

[night raptor]

I don't need that, I want to see the scene which shows all the colliders at once

[primal rampart]

how do i do that?

[night raptor]

You need to enable this #💻┃unity-talk message in scene view and enable everything from the Filtering section

where is dis?

@everyone I need Help, How to use smartphone keyboard to type something in an input field on Unity WebGL Builds ?

[still ingot]

Please I desperately need help I'm not understanding why my code is not working. Here is the code I added for my ledge climb script. Now the weird thing that's obvious in the clip I shared is the player will be shifted based on the offset that's great, but its not what I want. I want the players forward location to be offset by the ledge its facing. Also is it possible that I need to make the player a child of the ledge?

        Vector3 hangLocation = new Vector3(startTopPos.x + offsetX, startTopPos.y + offsetY, startTopPos.z + offsetZ);

        

        if (isHanging)
        {
            transform.position = hangLocation;
            rb.useGravity = false;
            rb.linearVelocity = Vector3.zero;
            playerObject.enabled = false;
        }

[rich adder]

no need to tag en entire server for this.. Luckily the command is disabled..
Anywho..
have you tried manually calling TouchScreenKeyboard.Open ?
https://docs.unity3d.com/6000.1/Documentation/ScriptReference/TouchScreenKeyboard.Open.html

[muted sand]

if y'all were to create a spawner of enemies (such as minecraft natural spawning), would y'all do so by using prefabs with monobehavior scripts attached to them, or with a monobehavior script running in the background that inserts all the prefabs into a list and does a function for each of them? i was gonna go with the first option as it seems more straightforward, but will it significantly impact performance?

[rich adder]

Personally I'd do the former, but I'd use Pooling for sure

[cosmic dagger]

Each enemy prefab would have a Monobehaviour script (if that's what you mean) . . .

[muted sand]

okay, thanks, pooling, as in spawning the items before they're needed?

[muted sand]

yeah, that's what i meant, i was thinking of one big script that controls all of them

[cosmic dagger]

But yes, you can pool them from a list . . .

[lean raptor]

You can give them a tag and put them under an empty GameObject. Then attach the MonoBehaviour script only to the parent object
and in the script check if the objects have that tag and move them however you want

[rich adder]

pooling as in recycling the old enemies so you don't have to keep instancing new ones

whether or not 1 script controls multiple enemies vs each controlling themselves thats more of a design question.

[muted sand]

okay thanks

[muted sand]

ima attach it to a prefab and then spawn them int

[cosmic dagger]

That works as well. You'd have a MonoBehaviour script containing a list of all the prefabs you can spawn (for that specific level/area) . . .

[muted sand]

okay, i'll do that, and have another script in each of the prefabs to control its behavior, thanks!

[silver fern]

can I assign a prefab to a variable in code?

[rich adder]

ofcourse

Prefabs are nothing special, they are just regular gameobjects

in most cases you want use a component directly on it if you have any besides the Transform one.

[silver fern]

I'm making a SO for each character that contains a reference to the prefab to spawn later, how do I assign that?

[rich adder]

just drag into it like you would any asset

[silver fern]

so I can't do it in code?

[rich adder]

You can do anything in code you can do in GUI

[naive pawn]

you can do anything in code, but that doesn't mean you should

[rich adder]

var thePrefab = //grab this however you like if not inspector, Resource, IO etc..
mySo.SomePrefab = thePrefab```

also true. Is there a specific reason you can't just drop the prefab in SO ?

[naive pawn]

for character SOs? i don't think you would want to do this in code

[silver fern]

there will be a lot of different SOs so I'd have to open up each one and drag and drop the corresponding prefab into each one individually which would be a lot more work than writing the path to the prefab in code or however one would do this

[ivory bobcat]

What's the current sample size?

[silver fern]

currently 32, possibly more later

[naive pawn]

you could have a serializeddict as an editor utility for this, probably

[silver fern]

what's that

[ivory bobcat]

Referencing from the inspector is part of the level/scene design. So by explicitly setting the field, you're certain that those SOs exist and that those fields are populated. Dynamically assigning the fields during runtime will not ensure any element, so do be aware that there is potential for undefined behavior. Populating the inspector using an editor function is perfectly fine as well, if you're wanting automation.

[naive pawn]

which part?

[silver fern]

what does 'serializeddict as an editor utility' mean?

[silver fern]

it's not really dynamically set, more like hardcoded from the start

[ivory bobcat]

ie context menu
https://docs.unity3d.com/6000.3/Documentation/ScriptReference/ContextMenu.html

[ivory bobcat]

Right.. so if hierarchy changes or new paths are added... expect stuff to not work. Debugging hell for the future you or others (paths may be incorrect, items may not exist etc).

[silver fern]

and if I drag and drop and change things around it'll keep track of everything?

[ivory bobcat]

Context menu for automatic population in the editor; to bypass redundancy.

You would access your function by right clicking on the component and selecting the context menu function you created to execute the function.

[silver fern]

I don't really know what you're talking about now

[naive pawn]

you could have a utility script/menu/etc for use within the editor, exposing a serialized dict for you to drag stuff into

[silver fern]

ok idk what any of that means so forget about that, I'll just drag and drop if that's how it has to be done in unity

how do I add scriptable objects to a list?

[rich adder]

same thing

either inspector or code

the process doesn't' change, SOs are assets, Prefabs are assets, Sprites are assets etc..

[silver fern]

for example, I have a scriptable object called LiskarmConfig and I'm trying to do something like private List<ScriptableObject> characterConfigs = new List<ScriptableObject> { LiskarmConfig };

but it tells me I can't use the class name in the list

[glossy tinsel]

does anybody know what this means

and if so anyway to fix it?

[silver fern]

it's something in your code

[glossy tinsel]

ye

[rich adder]

You don't have a type named Player

[glossy tinsel]

but what

[rich adder]

at least not in that assembly

[ivory bobcat]

It's telling you that it doesn't know what Player is

[silver fern]

how do I add the object if not like this?

[glossy tinsel]

im tryna learn so i might be a bit stupid i followed a tutorial

this is the tutorial

its like 7 years old so somthing might be old

[solar hill]

and what does your script look like?

or is the screenshot your script?

[glossy tinsel]

the screen shot is what i copied

now im tryna understand why it is what it is

[solar hill]

what does the tutorial show

do you have a Player class anywhere in your project?

[glossy tinsel]

this is the bottom

[rocky ledge]

you cant pass a class name directly into a collection initializer because the compiler expects an instance of an object, not a type blueprint, fixing the "Class name is not valid at this point" error in Unity, you must either reference an existing instance or instantiate a new one

[rich adder]

where is you Player class

[glossy tinsel]

i dont know :(

[silver fern]

but its just a SO with some character config, not something I can instantiate

[glossy tinsel]

im so confuzled

[solar hill]

Player player;

implies you have Player class in your project

[rocky ledge]

unity has a special method for instantiating SOs

[solar hill]

im noticing a discrepancy between class names from you and the tutorial

[glossy tinsel]

thats the tutorial

[solar hill]

so im going to assume you named your "Player" class something else earlier

[solar hill]

do you have any other script in the project?

maybe one you made earlier?

[glossy tinsel]

no

or ima check wait

theres one from the packages

but if i click the error it sends me to this one

[solar hill]

can you link the tutorial you are watching please....

[glossy tinsel]

alright

[rocky ledge]

new List<ScriptableObject> { ScriptableObject.CreateInstance<LiskarmConfig>() };

[glossy tinsel]

https://youtu.be/yfsqai3ivyA

[silver fern]

ok I think it's not going to work this way because I might need multiple instances, what's the best way of keeping a list of configs without instantiating?

[rich adder]

cursed

[rocky ledge]

sh

lol

[solar hill]

you didnt watch any tutorial before this?

this tutorial is obviously a part 2 or 3 of another tutorial

[glossy tinsel]

oh

i think my brain ahs been fried

[solar hill]

it says "Episode 19"

at the start of the video

[glossy tinsel]

damn

iv been fried from the inside

[rocky ledge]

wait what is your goal eactly

you can drag assets into a serialized field and access the mwithout isntantiating anything

[rocky ledge]

im sure you experienced unity folks have a ton to teach me im coming from c# and full stack dev lol

[silver fern]

so for each character I have an SO containing a reference to the prefab to spawn, and this is for a multiplayer game. so the goal is, when someone picks a character, the game takes the list index of the list of SOs, sends it to the server, and the server picks the SO from the list using the index and spawns the prefab referenced within. If multiple people pick the same character, they will need separate instances of it though

[mental spade]

have tried fixing this for way to long, no matter what I do it takes me back to this error, can someone help me

[rich adder]

nah it can be valid in certain circumstances but when possible the inspector can squash doubts better

[rich adder]

did you save and did it compile ?

oh wait..

[mental spade]

yeah

[rich adder]

this is a classic unconfigured IDE/Editor issue

[naive pawn]

configure your ide

!ide

[radiant void]

💡 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
• :question: Other/None

[rich adder]

do you have a class named Monobehaviour

[mental spade]

no?

[rich adder]

exactly

its the wrong one, and it should also be underlined red

https://docs.unity3d.com/6000.3/Documentation/ScriptReference/MonoBehaviour.html

[ivory bobcat]

MonoBehaviour

[rocky ledge]

so...as far as what i know..the best way to do this is a character data so to ensure the character configs inherit fro ma base class OR simply contain hte data

but youll need a single source of truht for your character database

[mental spade]

sometimes when i reload it, it is..

[rich adder]

c# as 98% of languages, is case sensitive

[rocky ledge]

both the server and the client will look at the characterdataabse list because the list order is the same for everyone

[hard fossil]

MonoBehaviour, not Monobehaviour

[solar hill]

honestly is there one that isnt case sensitive lol?

[naive pawn]

sql

[rich adder]

one more

[rocky ledge]

and when your server reciegvse the index, it instsantiates the prefab inside of it. always creating a unique separate instance of that character.

[ivory bobcat]

Your ide isn't configured. Folks are supposed to redirect you to configuring your ide to prevent simple unwanted spelling/syntax mistakes.

[glossy tinsel]

il be back in 2 days with a horrible stupid problem

[solar hill]

oh damn you right

to be fair writing sql feels like youre basically screaming the entire time lol

half the shit is in all caps

[rocky ledge]

@silver fern does that help

[naive pawn]

-# also shells kinda for some things if you're on a case-insensitive fs, but arguably that's not the language being case-insensitive

[rocky ledge]

bash 🤮

[rich adder]

a couple including SQL , Fortran, BASIC

[rough granite]

do you have any other errors in the console?

[rocky ledge]

$100 if you code your unity game in Fortran

lol

[mental spade]

no

[silver fern]

I'm... unsure

[rocky ledge]

honest question: have you made games before?

[rich adder]

this would still be configured if its not underlining red and you dont have such a class named Monobehaviour

[rough granite]

the other's are right though your ide isnt configured so bugs aren't showing

[silver fern]

yes but not with unity

[rocky ledge]

i only ask because you're gettijng into async stuff

and wanna make sure we're on the same page

[silver fern]

and also not online

[naive pawn]

yes, you should have a single source of truth for most things.

[mental spade]

how do i configure ide

[naive pawn]

!ide

[radiant void]

💡 IDE Configuration

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

Select one:

• Visual Studio (Installed via Unity Hub)

• :question: Other/None

[silver fern]

as far as I can tell I don't have multiple

[rocky ledge]

@silver fern especially for mp games, this is true

you should definiteyl have a "Source" object

so essentially it will contain hte data needed that both the client and the server can see

[silver fern]

thats the prefab

[rich adder]

on somewhat related note, check out these new features in VSC I just noticed
(gameobject in the serializefield is shown in editor)

[silver fern]

the characer prefabs contain all the information relating to the characters, but I need a list of them

[rocky ledge]

think of it this way: you have a book titled "Multiplayer Game", in that you have a chapter. the chapter describes only the characters in the book. the rest of the chapters use those characters from that chapter to buil the rest of the story.

[naive pawn]

why do you have SOs then?

[silver fern]

they have to persist across scenes

[naive pawn]

prefabs persist across scenes, their instances might not

prefabs are assets just like SOs

[silver fern]

idk I was told to make SOs to do this

[naive pawn]

are the prefabs for each character structured differently? eg they have different child objects/hierarchy setups

[mental spade]

i already got these tho

[rocky ledge]

@silver fern https://dev.to/snowman647/single-source-of-truth-d29 check this out

[naive pawn]

if not, you could consider making it so that the data is all on the SO, then you would only have 1 prefab that reads the data from the SO and does stuff appropriately

[naive pawn]

Restart Required

[silver fern]

I don't think that is possible because of all the different sprites and animations and whatnot that are different for each character

[rough granite]

i'm willing to bet this was ai generated ~_~

[mental spade]

i had them before all of this.

[naive pawn]

you can have an AnimatorController in the SO

[rocky ledge]

shrug if it has good information

[mental spade]

have restarted 23million times ATLEAST

[naive pawn]

ok, have you installed .NET from the .NET install tool?

[mental spade]

tried, didnt let me, can try again

[rich adder]

if it doesnt you can always manually download SDK
just reboot pc after

[naive pawn]

sure, if it still "isn't letting you", please elaborate on what the issue is

[naive pawn]

(also, once it's installed you'll have to restart vscode)

[silver fern]

what I'm trying to do is make a character selection menu that will tell the server what prefab to spawn in the next scene, basically

[naive pawn]

ok? that doesn't go against what i suggested though

[silver fern]

I don't know how to do that and it sounds like something that will cause me to end up in an unfixable mess again

[hard fossil]

You should try to reverse it, the server should make all the decisions, and the player should do simple things like send input to the server.

[silver fern]

ok but how do I tell the server what prefab to spawn then?

[hard fossil]

If you have a list of spawnable prefabs, the player can send input, left arrow, right arrow to the server, and the server can change the index of the selected prefab.

[silver fern]

that is gonna cause too many problems

if an input is dropped its an immediate desync situation

[naive pawn]

sure, we can go back to what you had before with separate prefabs.

what's the SO defining? just the prefab?

[mental spade]

installed it, restarted unity, still same error

[hard fossil]

In the long run, the more decisions the client side is making, the more prone to cheating. The server should be the truth, and the clients just predict a little, then correct.

[silver fern]

yeah right now it's really just the prefab

[naive pawn]

then the SO isn't really doing much, you can just use the prefab reference instead

[naive pawn]

what error? also restarting unity is not any step in this

[outer swallow]

[silver fern]

the other issue with that is that in that case the server would have to simulate every client at the same time in different states and it would be way too slow

[outer swallow]

Oh ok

[mental spade]

derive from monobehaiour when trying to add the script

[naive pawn]

that's what you're trying to do. what's the "error" you're referring to

note that configuring your ide is not supposed to fix errors

it is to let your ide help you fix them

[outer swallow]

Is there any severs for builders and coders chris

[naive pawn]

the issue right now is that the error/mistake isn't being highlighted within the ide, which is what configuring the ide is supposed to fix

[rich adder]

builders and coders ?

[mental spade]

okay

[hard fossil]

This is how professional multiplayer games with dedicated servers work. Getting something working is probably more important to you at this stage than thinking about cheating and things like that so I understand.

[outer swallow]

Like devs looking for teams other than this server

[rich adder]

places like The Coding Den I think

[silver fern]

thats for people who have a lot of money to run powerful servers

[outer swallow]

Link?

[ivory bobcat]

Try any of the other unofficial unity discord server, other social media platforms etc

[outer swallow]

Idk how to join there server

[mental spade]

well i downloaded the .net and it still does not highlight

[outer swallow]

Dms

[hard fossil]

You don't need to use dedicated servers to implement these methods though. Any multiplayer game working with host/clients can work this way. Usually, clients send signals to the host, and the host sends signals out to every client. It's not slow, it's standard.

[rich adder]

discord.gg/code

[silver fern]

this will be a free p2p game without dedicated server so it has to be able to handle 10 clients while running on a toaster

[rich adder]

pretty sure if you google these you find them
also GMTK etc.

[mental spade]

@naive pawn

[rich adder]

did you restart?

[mental spade]

yep

[naive pawn]

have you restarted vscode? (also to make sure we're on the same page, this is from the .NET installer in vscode, correct?)

[rich adder]

type dotnet --version in command

[naive pawn]

no need to ping me again.

[mental spade]

ye

[outer swallow]

I got in it how should i recruit people?

[tawdry helm]

I want to make a turn based RPG UI system for a 2d game but every tutorial I find uses canvas and I want a system where the UI is part of a character in the game moving through papers attached to them, with one option going to an inventory with a grid system. My questions are how can/should I move through the papers changing their sprites avoiding two being selected at once due to button mashing/lag and how can I make a zoom in/out to an item on the screen (bag that opens to reveal the grid system) avoiding the zoom to get stuck or permanently changing the zoom in the screen.

Hey does anyone know what's wrong with my I got my player to finally enter a hanging state but it seems to face the wrong direction? I coded it to face the normal of the ledge but that seems to not be working?

    private float CalculateLedgeHeight(RaycastHit ledgeRay)
    {
        //Represents y distance between raycast hit and top of ledge
        float ledgeHeight = 0f;

        //Get the top height of the mesh
        Vector3 topCollider = ledgeRay.point;
        topCollider.y = ledgeRay.collider.bounds.max.y;

        //Top point Y of the mesh
        var startTopPos = topCollider + Vector3.up * ledgeHeight;
        val2 = startTopPos;
        Debug.DrawRay(startTopPos, Vector3.up * -0.1f, Color.red);

        //Disable wiresphere
        if (!isLedge)
            val2 = Vector3.zero;

        ///////HANG ON LEDGE AT LOCATION BELOW///////

        //Create a forward Raycast
        if (!Physics.Raycast(startTopPos, Vector3.up, out RaycastHit hit, -0.3f))
        {
            Debug.DrawRay(startTopPos, orientation.forward * 0.1f, Color.red);
            isHanging = true;
        }

        //Stop the gravity and freeze the player speed and cancel jump animation

        {
            rb.linearVelocity = Vector3.zero;
            rb.angularVelocity = Vector3.zero;
            transform.forward = ledgeRay.normal;
            rb.useGravity = false;
            move.jumpButtonPressed = false;
            playerObject.center = new Vector3(0f,0.5f,0f);
            transform.position = new Vector3(transform.position.x, /*transform.position.y - */((ledgeRay.collider.bounds.max.y /2)), transform.position.z);
        }
        else
        {
            playerObject.center = new Vector3(0f, 0f, 0f);
        }

            return ledgeHeight;
    }

[rich adder]

you can try closing VSC go into UnityEditor under Preferences -> External tools and do Regenerate project Files

it might not work properly if you have compile errors though so may be why
fix the typo first if that clears compile error , try again checking if underlines error or offer suggestions

[naive pawn]

don't modify the transform, use rb.position/rotation if you want it to teleport while still keeping sync with physics

[ivory bobcat]

Log the normal and your forward. Also, I'm not sure if Transform and RB will play nice with one another.

[mental spade]

still looks the same

[tawdry helm]

Not as in I want the exact code btw I'm asking for the logic of it

Like a recommended approach to avoid problems

[mental spade]

what typo?

[naive pawn]

Monobehaviour instead of MonoBehaviour

[mental spade]

it is with a small b

no underline

[rich adder]

we know it was... we're saying that part of the "typo"

[ivory bobcat]

Maybe they've got the incorrect deprecated vscode package

[mental spade]

huh

[mental spade]

oh?

[naive pawn]

right so have that as MonoBehaviour, restart vscode/regen project files, see if it compiles and configures itself correctly

(eg afterwards, write Monobehaviour and see if the ide reports the error)

[mental spade]

now it does not correct

[rich adder]

what about random errors

did yu do the regen project stuff ?

wat happens if you ctrl + click the Monobehaviour ? does it take you somewhere

[mental spade]

yeah

[mental spade]

nope

[rich adder]

ok so if you didn't somehow accidentally create a Monobehaviour class.. its still not configured proper

[mental spade]

okay... hmm

[rich adder]

any errors in the Output tab of VSC?

[mental spade]

nope

[frosty hound]

It's https://docs.unity3d.com/ScriptReference/MonoBehaviour.html

Nevermind it's mentioned above, ignore.

[silver fern]

I made a SO containing a list of prefabs, I think that should work

[novel shell]

using UnityEngine;

public class CameraCollision : MonoBehaviour
{
public Transform target;
public Vector3 offset = new Vector3(0, 2, -5);
public float smoothTime = 0.3f;
public float collisionRadius = 0.5f;
public float minDistance = 2f;
public float maxDistance = 5f;

private Vector3 currentVelocity = Vector3.zero;
private float currentYaw = 0f;
private float currentPitch = 0f;

public float minPitch = -30f;
public float maxPitch = 60f;

void Start()
{
    Cursor.lockState = CursorLockMode.Locked;
    Cursor.visible = false;
}

void LateUpdate()
{
    if (!target) return;

    float mouseX = Input.GetAxis("Mouse X");
    float mouseY = Input.GetAxis("Mouse Y");

    currentYaw += mouseX;
    currentPitch -= mouseY;

    currentPitch = Mathf.Clamp(currentPitch, minPitch, maxPitch);

    Quaternion rotation = Quaternion.Euler(currentPitch, currentYaw, 0);
    Vector3 desiredPosition = target.position + rotation * offset;

    Vector3 direction = desiredPosition - target.position;
    RaycastHit hit;

    if (Physics.Raycast(target.position, direction.normalized, out hit, direction.magnitude))
    {
        float hitDistance = Mathf.Clamp(hit.distance - collisionRadius, minDistance, maxDistance);
        desiredPosition = target.position + direction.normalized * hitDistance;
    }
    else
    {
        float distance = Vector3.Distance(target.position, desiredPosition);
        float clampedDistance = Mathf.Clamp(distance, minDistance, maxDistance);
        desiredPosition = target.position + direction.normalized * clampedDistance;
    }

    transform.position = Vector3.SmoothDamp(transform.position, desiredPosition, ref currentVelocity, smoothTime);
    transform.LookAt(target.position + Vector3.up * 1.5f);
}

}

What am I doing to prevent it from detecting collisions properly?

I'm getting the typical error where it goes through the wall and there's no collision.

[rich adder]

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

also you should not move with transforms if you expect any accurate collision

[novel shell]

Then the code is wrong.

[silver fern]

you still can, you just have to do it differently

for example by checking overlap

[rich adder]

if you're making a "camera collision" you don't need to do any of this

Cinemachine already comes with a built in system for obstacle avoidance

how do you check if you collide with a building?

Is Cinemachine just a matter of installing it? I didn't want to use that kind of thing.

When I activate that script, the camera starts vibrating and can't be rotated.

[rich adder]

im confused what are you asking here what does damages have to do with camera

probably script is wrong / fighting controls over its rotations with something else

[novel shell]

So the camera respects the character's collision, but not the buildings'. I'll check if it's the building collision and let you know.

[still ingot]

I need help with this really transform.forward = ledgeRay.normal;

Is there a way to make the player's rotation face a mesh at all times?

Like climbing in the ledged of zelda: botw

or rather more like uncharted

[rich adder]

lookdir = (target - origin).normalized
quaternion.lookrotation (lookdir)

[still ingot]

Thanks! Now the player is facing the ledge perfectly and I am moving on to implementing the actual movement along the ledge.

    /// Move the player along the X axis of the normal of the ledge game object. 
    /// The speed is less than walking speed while hanging and climbing
    /// </summary>
    public void MoveOnLedge()
    {
        //Buttons
        bool leftButton = UnityEngine.Input.GetKeyDown("a");
        bool rightButton = UnityEngine.Input.GetKeyDown("d");
        bool upButton = UnityEngine.Input.GetKeyDown("w");
        bool downButton = UnityEngine.Input.GetKeyDown("s");
        bool jumpButton = UnityEngine.Input.GetKeyDown("w");

        if (leftButton)
        {
            //Move Player to the left along ledgeRay.hit.normal X-
        }
        if (rightButton)
        {
            //Move Player to the right along ledgeRay.hit.normal X+
        }

        if (downButton)
        {
            //Turn player in opposite direction Y-
        }
        if (upButton)
        {
            //Move Player to the top of the ledge Y+
        }
    }

[frail hawk]

not the best way of moving your player

could be 2 lines of code instead

[still ingot]

Really?

[frail hawk]

yes really

[whole lantern]

Okay, total newbie question (I am a total newbie, I have no experience in coding), but what would be the code that I use here for applying player movement? I've looked at the documentation for the new Input System, and I got this far, but I just can't find the code for applying the movement with the moveValue.

[frail hawk]

if you want to move physics based you could use the rb velocity or addforce

these 2 methods are always recommended

[honest marten]

yo i need help with making a 5 player online game for my comp science lesson i can make sprites and all that but im too dumb and lazy to code, if somone has like some basic project that i can steal it would be awesome

i can make soundtracks too i guess

[rocky ledge]

@honest marten youre doing cs but refuse to code?

[rich adder]

apply the values returned
if you're using a character controller look at examples like
https://docs.unity3d.com/ScriptReference/CharacterController.Move.html

[rocky ledge]

i can help but only in the context of helping you learn

[honest marten]

i mean i did make a platform game back in the day but multiplayer is another level man

on game maker..

[rocky ledge]

to be honest its not that bad, i assume youre learning about async?

asynchronous programming?

[rich adder]

this isn't the server for asking projects / do homework for you.. this is to help if you're stuck on a problem

[honest marten]

nah man im in highschool i just expand cs and math

[rocky ledge]

understood. well as i said i am happy to help but i wont write code for you

[honest marten]

dw

[rocky ledge]

you should learn and understand unity a bit first though no?

[honest marten]

is it possible to learn it in 7 days

[rocky ledge]

if you have an experienced background in something sure

[glossy tinsel]

im back with questions

why pixels be weird

[rocky ledge]

i would say going from no knowledge of game dev or programming would make both harder to learn conceptually

[rich adder]

why are you even taking computer science if none of this stuff intrests you to learn or actually do work

[honest marten]

i mean im in high school man

[rich adder]

this isn't even college?

[rocky ledge]

well, i would argue you should take it seriously anyway, if nothing else youll gain a new way of thinknig about problems

[rich adder]

why bother making a multiplayer then lol that seems overkill for some hs project

[rocky ledge]

think thats his assignment @rich adder

[honest marten]

idk the teach said that its a requirement

[rocky ledge]

do you HAVE to use unity?

if not, use something in python

far easier

[rich adder]

they would assign it if they taught it, they probably did no learning now wants to rush through

[rocky ledge]

quicker

[honest marten]

i can use anything

[rocky ledge]

ok

use python

[honest marten]

i could even make a game in roblox but i dont think im that lazy

[rocky ledge]

find some code for geometric shapes, make it squares and lines, make it a 4 player pong game, use libraries, done

all of that should be achievable i think

but again, you gotta like...at lesat have an idea of what youre doing

[honest marten]

what about something like claude code

[rocky ledge]

maybe, i dont know. you gotta make the call

[honest marten]

i used it once but it didnt make sense to me

[rich adder]

anyway this isn't the place for that

[solar hill]

yeah and they most likely gave you a few months to do it 🫩

[honest marten]

actually he said that i need to make a game til the end of june like 4 days ago

i mean may

but im not really a coder man

im a composer

[whole lantern]

Sorry, I'm really new to this. I'm not quite understanding what you mean by "apply the values returned". How would i do that, if you are able and willing to answer? the example script is so much different and more complicated than what i have, and I'm not at the skill level in coding to problem solve that yet. Sorry for the probably dumb questions

[rich adder]

it appears more complicated then it is because theres a lot of lines.
if you isolate the relevant parts to input and movement.
Vector2 input = moveAction.action.ReadValue<Vector2>();
Vector3 move = new Vector3(input.x, 0, input.y); // its applying vertical input (y) to the Z so it can move forward/back in 3d space, the x is side movement. in 3D

// Move
Vector3 finalMove = move * playerSpeed + Vector3.up * playerVelocity.y;
controller.Move(finalMove * Time.deltaTime);```

[whole lantern]

Thank you so much! A appreciate you, and I will be doing my best to research and understand all this!

[rich adder]

sure.
btw the inputs will return to you values -1 to 1 on each axis

[glossy tinsel]

im back

[rich adder]

You don't have to announce it lol

[glossy tinsel]

i couldent figure out why hes weird

[rich adder]

its clear once you post an actual question

[glossy tinsel]

announcments are a big part of the amarican culture

like santa

screaming when he comes into your house

[solar hill]

hilarious.

[rich adder]

go make a tweet then, on this server you don't need to spam

thank you

i dont know why but my adrenaline is spiking while doing this

Hey I implemented a MoveOnLedge function and my player moves along the ledge now! Here is what I have if anyone has an idea on how to turn the character when they reach a corner

    public Vector3 MoveDirection()
    {
        return Vector3.zero;
    }

    /// <summary>
    /// Move the player along the X axis of the normal of the ledge game object. 
    /// The speed is less than walking speed while hanging and climbing
    /// </summary>
    public void MoveOnLedge()
    {
        float horizontalInput = Input.GetAxisRaw("Horizontal");
        float verticalInput = Input.GetAxisRaw("Vertical");
        // calculate movement direction
        moveDirection = orientation.right * horizontalInput;

        rb.AddForce(moveDirection * 0.1f, ForceMode.Force);

        if (Mathf.Abs(moveDirection.y) == 0f)
        {
            moveDirection.y = verticalInput;
        }
        else
        {
            moveDirection.y = verticalInput;
        }

        if ((Mathf.Abs(horizontalInput) == 0f))
        {
            rb.linearVelocity = Vector3.zero;
        }

    }

bro what the fuck are you watching in the background

[still ingot]

Sorry was a podcast

[rich adder]

jfc good thing my audio was muted

[solar hill]

i just blasted that full volume on my speakers 😔

[still ingot]

I can make one with no audio

[solar hill]

no its fine lol it just caught me off guard

[still ingot]

but I would like to share this code with others when im done

im trying to make an easy way to ledge climb

[rich adder]

could probably do it in #1179447338188673034 when done

maybe updates in #1180170818983051344

[hybrid gust]

is there a way I can get the frequency and damping behavior from a SpringJonit2D on a SliderJoint2D?

Or conversely can I get the behaviour provided by the angle parameter from a SliderJoint2d for a SpringJoint2d?

nvm idk why i thought i couldn't use both components on the same gameobject that had bad results

[clever prairie]

guys where can I find a tutorial or guidebook for all of the common physics and rigidbody scripts? I made a few scripts using AI, but, I wanna fix some details on them and, since Gemini cant code them correctly, I'll have to learn how to code them myself.

[vivid quarry]

Heyoo, I was wondering what the best way is to determine if an object is being occluded by a wall? Raycasting to AABB corners works fine for something like boxes, but when trying to determine if a sphere is being occluded, raycasting to the AABB corners doesn't work well. I tried using sphere casting but that can lead to false positives as it can get caught on the edges of the wall. Is there another way that is most accurate that I could go for?

[night raptor]

Could you explain the context around this issue? What you need the occlusion information for? One common solution is to fire a larger number of rays in some kind of grid pattern. There is no fast and perfectly reliable (never false positives or negatives) occlusion algorithm. Well technically you could render the image to an object ID buffer and calculate the occlusion from there in a compute shader for example but the problem with that is that even though it could probably be implemented pretty fast, there is no fast readback from the GPU so there will be couple frames of delay to get the information back to C# side

[vivid quarry]

basically I just want to check if the object can be seen by a player

[vivid quarry]

Hmm yeah I may need to find a better solution then. The goal is to have like ten of these enemies moving around, so I fear that may get expensive and slow very quick.

[vivid quarry]

sorry i just realized this doesn't really clarify much beyond my original statement lol. If a player is looking at an enemy, then the enemy freezes and is unable of moving like SCP 173.

[teal viper]

Do you really need near perfect detection though? Is one ray at the center not enough?

[rich adder]

You can make some points manually to raycast to

[vivid quarry]

Well, I want to eliminate the possibility of a player being able to see the enemy move as that'd ruin immersion. It's a horror game so preferably I would want to reduce the chances of them seeing the enemy move.

However I suppose I could do some prediction and flicker the lights or something like that if not possible. That would theoretically prevent the player from seeing the movement 🤔

[solar hill]

im confused, is the player ever supposed to see the enemy then?

i feel like this is an xy problem more than anything

[night raptor]

I think the point is the player is never meant to see the enemy move

[vivid quarry]

Sorry I may be a bit unclear. They are supposed to watch the enemy because they don't want the enemy to get closer to kill them, so ideally you want to be looking at them. What my problem is, I want it to be accurate because I don't want them to be able to see the enemy moving.

[solar hill]

i feel like theres a simpler way to accomplish that

then dealing with perfect ray detection no?

[teal viper]

I see. In fact you might be overthinking the performance impact of raycasts. If you don't have much else going on, it might be totally feasible to make many raycasts. And you can combine it with frustum culling to improve efficiency

[solar hill]

Yeah raycasts are as cheap as they come

[vivid quarry]

well, I want the enemy to be able to move when the player is not looking at them, which would include being behind a wall. Though they'd be visible if parts of their body were visible around the edges of the wall. I'm not sure how else I would be able to accomplish that without perfect ray detection

[solar hill]

which perspective is this game in?

first?

[vivid quarry]

First person

yeah

[solar hill]

couldnt you just use something like "Renderer.isVisible"

basically the enemy listens to the player, to see if it can move at all

[teal viper]

That's the frustum culling part.

It would be true behind walls

[solar hill]

yeah but in a combination with a raycast you dont need much more no?

[vivid quarry]

hmm I'll need to test that

[solar hill]

i might be overthinking it, and it could be overkill, but if you want to ensure that even if a smidge of the enemy is peaking around the corner, you could get the enemy's 3d boundaries as 2d screen coords and then basically hit it with a lidar scan of raycasts lol

[teal viper]

You can also provide simpler colliders, like boxes for your enemies to do less raycasts. It might stop moving a little earlier, but small margin shouldn't be a problem, right?

[night raptor]

I think that would be very reasonable approach. One probelm that I'm wondering just now is that if you have shadows enabled, you might see that shadow moving even though the object itself is not in view, would that be an issue? isVisible I think returns true also when it is visible to some of the shadowmaps but if you need to take that into account in your raycasting logic, it would quickly get really complicated

[vivid quarry]

Oh yes, the shadow will be a problem. I need to account for silhouettes as well

[solar hill]

the shadow thing doesnt seem so bad

honestly from a design perspective more than anything

could be a cool problem turned feature

[vivid quarry]

The enemies don't walk. They just teleport so it would look kinda funky haha, but maybe it'll look cool. I did it this way as it is a multiplayer game, and it would be possible I believe, due to latency, that you could see the enemy moving if it was with just default walking.

[solar hill]

oh i got some bad news

if its a multiplayer game, theres almost 0% chance you can guarantee the enemy wont ever be seen moving

unless its movement is entirely client side

[night raptor]

I mean you would get closer by increasing the margins (like the size of their colliders) enough

[teal viper]

Multiplayer kinda makes it 10x more difficult, as you'll either need to simulate every player camera on the server, or deal with latency uncertainty.

[solar hill]

latency is gonna be the biggest issue

[vivid quarry]

yeah you're right aghh

[solar hill]

i cant think of a single multiplayer game with this kind of mechanic thats done it proper justice lol

even scp secret lab try as they might cant get scp 173 to look good

its just a flying peanut half the time lol

[vivid quarry]

then no matter what I'll have to probably make it so, if a enemy is somehow moving into a player's perspective and is not frozen, perhaps I'll just flicker the lights on the client for however long the duration must be

[vivid quarry]

ive been working on this game for 5 years haha. The first 4 were on Roblox. I am dedicated to making this mechanic almost perfect

[solar hill]

smoke and mirrors can get you pretty far

your light flickering idea is already there

[still ingot]

I made an attempt at trying to get the player to rotate using a spherecast but it doesn't seem to work?
Code:

    private void CheckCorners()
    {
        ///////Rotate around corners BELOW///////

        //Create a forward Raycast
        if (isHanging)
        {
            Debug.DrawRay(LeftChecker.position, move.orientation.forward * 1f, Color.red);
            Debug.DrawRay(RightChecker.position, move.orientation.forward * 1f, Color.red);

            if (!Physics.Raycast(RightChecker.position, move.orientation.forward, out RaycastHit lineHit, 1f))
            {
                if (Physics.SphereCast(RightCornerCheck.position, .1f, move.orientation.forward, out RaycastHit sphereHit, 1.5f, whatIsLedge))
                {
                    Vector3.Slerp(transform.forward, sphereHit.point, 1f);
                }
            }
        }
    }

I have a raycast that checks for when there is no ledge on the side. I then create a sphereCast that is supposed to hit the side of the wall around the corner. When it hits the player is supposed to rotate around to the hit point but it isn't functioning properly like how I intended. I might have to create a ray from the side of the wall in stead of a sphere.

[teal viper]

You're not using the slerp result in any way.

And the params are all over the place as well. A is a direction, b is a position. T is 1, so the result would always be the sphere hit point(position).

P. S. You should use debug rays and other gizmos more actively for visual validation. Make sure to use different colors too to make it clear what's what.

[waxen jasper]

Okay i have a design question in my first ever Unity game. My game has multiple rounds. In each round, the player drops all of the balls they have down a pegboard. In between rounds they can add balls to their collection.

My question is, how do i store all of these balls in a list that persists between rounds. I’m confused because the actual game objects won’t persist, but i still need to know what balls are in the users collection
Btw these different balls behave differently, it’s not just a different sprite

[rich adder]

https://learn.unity.com/tutorial/implement-data-persistence-between-scenes

[waxen jasper]

I guess I’m more asking how to store the balls

Instead of a list of game objects

A list of what

[upbeat nebula]

can't you just write in files? or store the data in a singleton?

[upbeat nebula]

huh?

[rich adder]

whatever type your balls are? if they have specific component use that

List is generic you can put whatever you want as long as the type is the same

[upbeat nebula]

Anyone learned the HSM? (hierarchial state machine)? if you did, what resource you checked to learn it cuz rn im confused

[waxen jasper]

But can i have instances of the type my balls are, without having game objects to go with them

[rich adder]

you mean physically ? cause in most cases you just store the data so destroying (via scene change) for example would have no impact

[waxen jasper]

Let me reword bc i think I’m confusing myself and you guys on what I’m asking

During the round the user will have a bunch of balls to drop, which are game objects that are destroyed when they reach the bottom. But even when the game object is destroyed i still need a list keeping track of all the balls they have currently bc they drop them again next round

I was under the impression that one instance of my hall class is made per game object

[rich adder]

yes which is why I said normally you store the Data itself not the instances of gameobjects

[waxen jasper]

Okay so i need to store data that describes the ball

[rich adder]

yup

[waxen jasper]

And the prefab would be included in that data?

[rich adder]

the prefab is a blank slate until you feed it the data

normally a SO is used

[waxen jasper]

Like let’s say I have prefabs for different kinds of balls

[rich adder]

POCO works too

[waxen jasper]

Then i store a list of balldata

Where the prefab is included

[rich adder]

If they have completely different prefabs then you could store the preab too ig

[waxen jasper]

What’s SO and POCO

[rich adder]

ScriptableObject
and Plain Old Class / Clr object

[waxen jasper]

Ah okay

Well i can make a scriptable object i was planning to do that after your recommendation

But the SO needs to store the prefab right?

[rough granite]

using POCO rn and it's annoying cause i always get "MissingReferenceException" whenever i stop runtime

[rich adder]

strange.. depends how you're using it though

[rich adder]

you can store it in a plain class as well , what makes easier in SOs is they are templates you can create instances of In inspector

[rough granite]

well the plain class has reference to a few monobehaviours when runtime stops they cry cause they are now missing and GC hasn't cleaned the plain classes yet
(ps sorry for popping in the middle of a conversation)

[waxen jasper]

Okay you may have technically answered this in something you said, but I’m a bit lost on one thing. Let’s say i have a scriptable object, which has data to represent a type of ball. If I’m not storing a prefab, how can i actually make a game object from that SO

[rich adder]

strange but not sure cause I don't remember if I haver used any MBs in POCOs

[rich adder]

what exactly do they have in common, most of those go in Prefab

what kinda data do they hold

[waxen jasper]

Wait what kind of data does what hold

[rich adder]

balls ?

[waxen jasper]

Well that’s the thing i don’t know what it should be holding

I’m thinking it needs to hold the type of ball it is
