Hi everyone, I'm a noob at unity, so I'm asking for help on how to transform .bland in .unity3d? I use the mod in the 7days, where I can use the models, but I don't understand how to convert these files normally(

[sour fulcrum]

we cant help with mods, sorry

[inland ruin]

As I understand it, converting files from the same blender or other formats to unity3d doesn't have much to do with mods, but maybe I'm wrong?

[sour fulcrum]

idk homie your the one who brought up the mod side of it, not me 😛

Unity uses .obj and .fbx files, you'll have to find a blender discord or other support online for exporting

[keen dew]

Converting things to the unity3d format is only done for modding

[pallid holly]

Guys, I wrote this code to make my player (a cube) move but it passes through walls. Can you give me some advice?

[teal viper]

Well, are you doing anything for it not to pass through walls?
Generally, that's the responsibility of physics, but with transform translate you ignore physics almost completely.

[pallid holly]

ah I understand and what can I use in post to translate to make my player move I'm new and I'm just learning

[teal viper]

"In post"? 🤔

[pallid holly]

Oh, I understand, and what can I use in the project (code) to make my player move? I'm new and just learning.

sorry for bad english i'm italian

[teal viper]

There are various ways. The simplest ones are applying velocity or force to a rigidbody or using character controller component.
But I recommend you learn the basics properly:

!learn

[teal viper]

Or follow some tutorials online.

[pallid holly]

So I think I'll learn the basics thanks to !learn. Do you think it helps a lot?

[teal viper]

Yes

[pallid holly]

Yes, I was following a tutorial on Udemy but even in the tutorial where he followed it he did this and had this problem but it didn't solve it.

[pallid holly]

thx very much

[teal viper]

If a tutorial has an issue and they just let it be, then it's probably a very bad tutorial.

Also, if you want to grow as a developer I recommend improving your English. It's indispensable for a developer.

[pallid holly]

yes then I think I'll leave him alone and not follow him anymore

[pallid holly]

Thanks a lot for the advice I'm working on this too I'm about to start taking a Cambridge ❤️

you say that with !learn I can learn everything about the basics and then start doing a first mini project

[teal viper]

Basically yes.

Reading the manual and the api docs can also be very helpful.

yes I think these days I'll read everything and start with the Unity Learn Pathways

Do you have any advice on where to start?

[teal viper]

There are specific beginner pathways. You should see them on the main page.

[pallid holly]

yes I saw that there are many and they last 12 weeks so I was wondering which one I should start with

[errant breach]

Hello ! Im trying to play a death particle for enemies.
My particle is a prefab, given as a gameObject to the enemy. When he dies, the particle is Instanciated but as a child.
Because the enemy is destroyed at the same time, so is the child.

How can i make the particle is not instantiated as a child ? I tried looking on the web but it doesnt work.

• public ParticleSystem TestParticle;
• Instantiate(TestParticle, transform.position, transform.rotation);

Thanks for the help !

[sour fulcrum]

set the particles parent to null

[errant breach]

Nice ! So there is a way ! But how can i do it please ? Because my prefab does not have any code 😅

[sour fulcrum]

Instansiate returns the thing it's creating

you can reference the particle via that

Is see, thank you ! Im trying to read the documentation but i really dont understand how it work... Do you know a tutorial that explain this easily ? Because ive watched a lot of instantiate's tutorial but i've never seen such thing. Or if you know how to achieve this in my scenario, i would be very grateful !

[subtle mulch]

we said yesterday to go look at tutorials on how to actually make a player controller

using transform is NOT how you make a player controller

[pallid holly]

yes bro but I wanted to ask for some advice then honestly I think I will do all the Unity courses so I can learn better if I already know something I will repeat it

thx very much ❤️

[subtle mulch]

there is a component called Character Controller btw

you should use that

[pallid holly]

bro I told you I'm new now I'm going to follow all the courses so I think I'll learn thank you very much for everything

[subtle mulch]

yeah i was just saying what you should look for

[pallid holly]

yes yes I understood it I really appreciate it a lot

[nocturne hawk]

wanting to make a reader/engine in unity to get data from .josn's for dynamic game character building for a 2D game, how can I find a 1:1 tutor?

[subtle mulch]

you can literally find hundreds of tutorials on YT for that btw

and they are free

[sour fulcrum]

you never find 1:1 tutorials

[subtle mulch]

i think he meant a Tutor (a real person that will help him)

[nocturne hawk]

tutors lol not tutorials loool

[sour fulcrum]

you will find a 1:1 tutor with money

[nocturne hawk]

ye that was the idea

[sour fulcrum]

and a place on the internet that offers those services

[subtle mulch]

yep, that's why you should go for YT tutorials

[sour fulcrum]

there's no paid type stuff on this server

[naive pawn]

why not use the free resources available tbh

[nocturne hawk]

cus idk what I need / am looking for

[subtle mulch]

well, you explained in your message, read a json file, also, no one will help someone that doesn't know what they need

[nocturne hawk]

I knoe what I want I just have 0.1/10 coding experience

[subtle mulch]

and that's why you can search in youtube

[teal viper]

That's the point where you go and learn coding.

[nocturne hawk]

can I shoot an explanation here and mabye some1 can tell me what to look for?

[subtle mulch]

ye

[teal viper]

Or you can pay someone on upwork to code it for you.

[midnight plover]

Go through basic tutorials on c# or on unity learn and learn how to gain knowledge. Going through this with a tutor might lead to spoonfed knowledge you gonna lose or dont even know how to translate in any context later.

[sour fulcrum]

paying for a tutor is totally valid too, just not something offered here

[nocturne hawk]

where do yall recommend if I go for this option?

[subtle mulch]

fiverr or upwork prob

[naive pawn]

don't have any ngl lol

those are freelance sites, not sure you'd get quality tutorship there..

[subtle mulch]

you might

tho they normally are pretty expensive+

[sour fulcrum]

1:1 education is inherently expensive, theres no getting around that

[midnight plover]

I think we can conclude the topic then, as long as you dont need any help with code yet to not clutter up this channel

[naive pawn]

remember: everyone started there once, you can learn anything if you put your mind to it

[nocturne hawk]

character hitbox and collision box info on different states, keybind triggers, attack functions etc inside .jsons, I got examples, { "on_state": { "idle":[ { "binding_boxes": [ {"hurtbox":{"x":100,"y":160,"offset_x":0,"offset_y":0},"collisionbox":{"x":110,"y":165,"offset_x":0,"offset_y":5}} ] } ], "dash":[ { "binding_boxes": [ {"hurtbox":{"x":60,"y":80,"offset_x":0,"offset_y":0},"collisionbox":{"x":110,"y":165,"offset_x":0,"offset_y":5}} ] } ] } } For providing the hitbox on different states for example

[subtle mulch]

yeah

make a script that reads it

[nocturne hawk]

thats where Im at

[subtle mulch]

converts to some struct

[nocturne hawk]

ye, how lol

[subtle mulch]

and then process the struct

[nocturne hawk]

i Know 0

[subtle mulch]

by using C#

[subtle mulch]

and YT tutorials

[nocturne hawk]

yes C#

tip: google is a very powerful tool

[subtle mulch]

guys, I'm trying to get a specific shader look for my game (im the game designer, not developer)
is it true that I can get a shader with pure code, without using shader graphs in unity ? I want a specific anime look

[subtle mulch]

well, shaders are code

[nocturne hawk]

thx for the help

[midnight plover]

Dont use a tool if you dont know the craftmansship. Get your basics up first 🙂

[sour fulcrum]

all shaders are pure code yes, shader graph is just a way to visually create them

[subtle mulch]

and you don't do shaders in C#

#💥┃post-processing #1390346776804069396

[pine elm]

interesting, would Úou recommend using AI for it ? or AI isn't good enough yet for unity shader codes ?

[subtle mulch]

thesere are prob the places you are looking for

[sour fulcrum]

most people here wouldnt recomend ai for anything

[subtle mulch]

don't use AI unless you already know what you are doing

[naive pawn]

@nocturne hawk
if you aren't familiar with c#/unity in general, i'd suggest learning that on its own first, eg working with the editor to familiarize yourself with the concepts, etc
doing that, and then adding the json-defined values, would be easier, rather than learning the entire workflow at once

[sour fulcrum]

shaders are written in HLSL, lot of stuff online for you to read or watch

[pine elm]

my unity dev is really experienced in unity and c sharp, I will not be the one using it

[subtle mulch]

well, shaders are NOT C#

they are their own languages

[pine elm]

its hsls

[naive pawn]

close

[pine elm]

hlsl

[sour fulcrum]

halal snack language

[pine elm]

lmao

so i need a guy that can write in that halal language

damn

[subtle mulch]

or just learn it

[pine elm]

could my dev learn it fast ?

if he knows c sharp

[subtle mulch]

maybe?

[sour fulcrum]

not neccasarily

[subtle mulch]

the logic is nearly the same

but you don't have classes

[sour fulcrum]

the logic being the same isnt really the problem

its a very different kind of work

[subtle mulch]

it's more similar to C tbh

[sour fulcrum]

its maths on maths

[pine elm]

so in theory, he could use AI, and then try and modify / fix some element of it to get the rendering objective

[naive pawn]

faster than starting from absolute 0 i guess, since they'd already know some core concepts like how strings work or matching braces

[subtle mulch]

no

don't

[sour fulcrum]

Honestly i'd just suggest looking for a third party asset to work from/with

paid or unpaid

[naive pawn]

i mean, that's the AI companies' theory i guess. they want you to believe it's all-powerful :P

it's.. not quite there.

[pine elm]

I do intend on simply using toon shader assets from the store

[naive pawn]

you still need to know what you're working with

[subtle mulch]

https://github.com/EricHu33/AnimeShadingPlus-Anime-Toon-Shader

[pine elm]

but I would have prefered being able to make it from scratch to get more customization possibilities

[subtle mulch]

maybe this?

[pine elm]

well I had 2 or 3 in mind

I never heard of that one

looks cool though

i had the unity toon shader in mind for instance

[pine elm]

apparently a lot of dev are using ai for 80% of their code today

[subtle mulch]

nope

not even close XD

[pine elm]

it's made a lot of progress recently, mainly through claude

lol, I guess it depends on the environment yea

[subtle mulch]

those percentages are very inflated

and if they use it, they just use it for autocomplete / comments

[pine elm]

right

[subtle mulch]

or repetitive tasks

[naive pawn]

also, look what it's doing to the ecosystem lmao

[subtle mulch]

and to RAM / SSD prices

[pine elm]

yea thats indeed a real drawback

[naive pawn]

i mean the dev ecosystem here. the real environment is also a concern just not what i was referring to

[pine elm]

but surely, we will find a way to create new source of unlimited energy thanks to AI right, right ?

[subtle mulch]

no

at the current stage, nope

not even close

[midnight plover]

At least we will keep on having this topic in the coding channels daily now...

[naive pawn]

yeah, unlimited positive charge... just ignore the fact electricity is negative...

[pine elm]

i guess my follow up question doesnt have a place here too then : also from my understanding, shaders are one thing, but texture is as important as shaders

😄

[naive pawn]

this is the coding channel

[subtle mulch]

textures are simple tbh

[pine elm]

can't you code texture ?

[naive pawn]

#1390346776804069396 would be able to more adequately answer

[subtle mulch]

no

you cannot "code" textures

you can generate textures

via code

[naive pawn]

you can for some definition of "code", but it's certainly not our expertise

[subtle mulch]

but not "code" them

[sour fulcrum]

the difference your trying to make is nonexistent

[naive pawn]

i mean, everything on the computer is code. but you aren't gonna be asking us how pixels physically work

[pine elm]

you also generate shaders, you don't code them right

[naive pawn]

you can write shaders

this.. is not the proper channel for discussing shaders either

that would also be #1390346776804069396

[pine elm]

ok I will go there then, thanks for the answers guys though 🙂 really appreciate it

if we have some coding questions I'll be back

[naive pawn]

just because everything relates to code, or everything can be done by code, does not mean this channel is appropriate to ask in

imagine asking a fullstack developer how to make generative/procedural art lol. they might be able to do it, but that's not their professional expertise.

[pine elm]

ahah yea I was messing around x)

have a good day folks

[real thunder]

I messing with homing algorithms and I ve encounered... math
so through using the augmented proportional navigation homing I am getting a centripetal force
other basic algorythms I use just rotate transform like that

      target_rotation = Quaternion.LookRotation(to_target_prognosed - transform.position);
      transform.rotation = Quaternion.RotateTowards(transform.rotation, target_rotation, angularVelocity * Time.fixedDeltaTime);

question is: can anyone help me figure out a way to transform a centripetal force into rotation inbetween quaternions or transform rotation inbetween quaternions into a centripetal force?
going the second route I got

      float force = rb.mass * R * angular_velocity  * angular_velocity;

where R meant to be a radius I should somehow get from two quaternions... tricky math rabbithole it seems
any useful ideas?

I want to have those algorithms behave on same terms so I could compare

[naive pawn]

centripetal force in concept is a linear force, not rotational - what exactly is the behavior you're trying to get?

[real thunder]

yeah this is annoying
there is a "augmented proportional navigation" algorithms used for homing missles sicne WWII given what I read is true
and the formula (I understand inputs but I have no clue why it considered optimal) have a centripetal force as an output

not a torque or a quaternion rotation....

[naive pawn]

if you're trying to get it to rotate how it does physically, like a ball on a string or tidal locking, you would just have the object rotate to face the pivot

[naive pawn]

hm, maybe it's using an equivalent/analogous circular motion?

i guess centripetal force encodes the curvature, assuming you already know the thrust/velocity?

[real thunder]

that formula even got a magic number in it

[real thunder]

yeah I am pretty sure there is a way to convert

sadly I suck at geometry and asking here if anyone can speed up my struggle

[real thunder]

also I don't understand what that means

[naive pawn]

torque affects the rotation of the object, while centripetal force affects the trajectory

so if you want a certain trajectory, you would figure out the arc, then the centripetal force required to get that arc, i guess? and then from there you can calculate the gimbaling or control surface movement to get that centripetal force

[naive pawn]

this would be a physics thing rather than a geometry thing
centripetal force F_C = mv^2/r, so if you know the forward velocity, mass, and centripetal force, you can calculate the radius of the circle you travel along (or 1/r for curvature, if you need that)

[real thunder]

in that case, I would need to get a Quaternion change out of radius

jut to clarify
I got two homing algorithms (still finishing writing the second one, ugh, but it should work)
one is straightforward where I just calculate mean intercept position and get a LookAt quaternion and RotateTowards
another meant to be more effective for evasing targets but formula only gives me centripetal force
I want to make them use one same method of rotating the missle

[sage mirage]

Hey, guys! I have a question. How I am supposed to get a reference to my emission of particle system?

I have used the Particle System itself but it doesn't allow me to get reference to it

you know what I mean the property of the particle

I am getting this

[naive pawn]

seems like you're trying to use it in an invalid context, given that it's complaining that the type isn't found

show some more context there

[sage mirage]

What I want to do is to Lerp from one value of my emission rate to another

but I cant get reference to my emission

[naive pawn]

angular velocity ω = v/r, you can probably get that more easily from that

[sage mirage]

maybe I need emission module?

as well

[naive pawn]

the error here is unrelated to how the particle system is set up, it is a compiler error

you likely have some syntax errors above that make this access not correctly parsable

[sage mirage]

No the problem is that I have to access the property I think otherwise I wont get reference to it

its like getting out the override/effect of post processing

you cant change directly from a post processing volume any effect you want, you first have to extract it lets say

[real thunder]

and then get a Quaternion out of angular velocity? that might work

[naive pawn]

yeah, ω = Δθ/Δt, so Δθ = ωΔt

(i'm using physics symbols/terms here out of familiarity/habit, if you need clarification on anything just ask)

also if you're using an rb, you could also assign to angular velocity

hm, this doesn't encode direction.

i'm thinking in 2d

[real thunder]

well the direction is to the intercept point

[naive pawn]

are you in 2d or 3d?

[real thunder]

it's 3d but the plane of interception is easy to find

[naive pawn]

ah, alright, that should work i think

[real thunder]

yeah now given that and one post I found "Rotation quaternion to angular velocity" I got all the pieces

time to cobble them

Hey everyone, im trying to make so my enemies have both a colliderBox (to get damaged) and a DetectionBox (given as an invisible square, child of the enemy).
The issue is that using "OnTriggerEnter" make the enemy take a damage even if the player only hit the DetectionBox. How can i make so that the two boxes are different ? Thanks for those who can help !

[polar acorn]

Multiple colliders on one object basically become the same collider (which you might see referred to as a "composite collider").

You'll need to put one collider on a child object, then check which object you hit to determine if you should deal damage.

[brazen pumice]

I'm trying to get a mario kart style ghost system, using a gameobject that adds my players location to a list, then creates a copy and passes the list of positions over. However, I keep getting a Specified Cast is not Valid error

[subtle mulch]

well, that error tells us nothing...

[brazen pumice]

yeah that's what I thought lmao

[subtle mulch]

send your code

[brazen pumice]

{

    List<Vector2> positions;

    public Transform player;
    public GameObject copy;
    public bool isRecording;

    private GameObject clone;

    void Start()
    {
        positions = new List<Vector2>();
    }

    void FixedUpdate()
    {
        Record();
    }

    void Record()
    {
        positions.Insert(0, player.position);
    }


    public void createClone(Vector2 spawnPos)
    {
        clone = Instantiate(copy);
        clone.GetComponent<dummyMovement>().positions = positions;
        positions.Clear();
    }
}```

[subtle mulch]

and the exact line where it fails

[brazen pumice]

it's the clone.GetComponent<dummyMovement>().positions = positions;

[subtle mulch]

what is dummyMovement?

[brazen pumice]

{
    public List<Vector2> positions;

    void Update()
    {
        Replay();
    }

    void Replay()

        }
    }

    public void setPositions(List<Vector2> pos)
    {
        positions = pos;
    }
}```

[subtle mulch]

bruh, why did you name it with a lowercase at the start...

[brazen pumice]

i didn't name it lmao, collaborative game jam

[subtle mulch]

pls rename it

it's so confusing

now

show me the prefab you are passing as clone

and also what the error says precisely

[twin pivot]

try making the list public

[subtle mulch]

that's what i was thing too yeah

it might interfere

tho it would be very strange

[brazen pumice]

no change, unfortunately

[twin pivot]

whats line 35 on the copy script

[subtle mulch]

clone.GetComponent<dummyMovement>().positions = positions;

he said it before

[silk night]

are you sure the clone contains a dummy movement?

[twin pivot]

it has no errors in the editor?

[subtle mulch]

yeah

he showed it in the screenshot

[silk night]

no he showed some object, doesnt mean that one is linked in the clone field

the only cast in that process is done on the dummyMovement generic

so if it can't cast to it theres something smelly going on with it

[subtle mulch]

also @brazen pumice
GameObject clone = Instantiate(copy, spawnPos, Quaternion.identity);

clone.GetComponent<dummyMovement>().positions = new List<Vector2>(positions);

try this

[silk night]

btw to make this a bit easier

public dummyMovement clonePrefab;
[...]

var clone = Instantiate(clonePrefab); <-- clone is automatically of type dummyMovement

[subtle mulch]

will it have every other component too tho?

[silk night]

yes, you drag the prefab with all other components into the inspector field

[subtle mulch]

oh cool

[silk night]

it just returns the component instead of the gameobject when you do it like this

[twin pivot]

you never made a list here

[silk night]

he doesnt need to

1. he is writing a new List into it
2. Unity serialization will write one into public fields

[subtle mulch]

and?

he is trying to set one in that script

not get it

[twin pivot]

worth trying still

[subtle mulch]

nah

[brazen pumice]

ok I fixed the error with this, thanks!

and I sorted out the name haha

[subtle mulch]

np

[polar acorn]

Make copy of type dummyMovement and skip the GetComponent. Instantiate returns the type you give it, so by making your prefab of type dummyMovement it will just return that component directly

[real thunder]

assuming I copypaste code from a system where Vector3.Cross(a,b) is ruled by right hand rule into unity where left hand rule is working I should just add negative sign to it? Am I getting it right?

[naive pawn]

depends on what you're using it for

[real thunder]

oh no, it's complicated

[naive pawn]

["first time?" gif]

if you're using it for display, where you'd need the result to point in the same direction, you'd negate it
if you're using it for other calculations that would be based on the coordinate system, you might not need to

[brazen pumice]

one of my fixedupdates is going faster than the other lmao

[naive pawn]

either it's being called by something it shouldn't, or you're reading the wrong thing

[night raptor]

Based on what you have concluded that? Unity calls every fixedUpdate exactly once every physics step, there's no faster or slower unless you do something wrong as Chris suggests

[wintry quarry]

What makes you think that?

[brazen pumice]

becaused i did something wrong lmao

[real thunder]

sigh, this meant to be the homing code and fiddling with Vector3.Cross didn't help
originally this is from right hand coordinate system thingie
homing works.... the other way around
the projectile is pretty effective at flying away from the target
what have I even done wrong
if you have a clue what's wrong with that please tell

public float max_accel;
    public float N = 3;
    void PurePN()
    {
        Vector3 to_target = target.position - transform.position;
        Vector3 closing_velocity = targetRb.linearVelocity - rb.linearVelocity;
        float to_target_distance = to_target.magnitude;

        Vector3 angular_velocity_of_los = Vector3.Cross(to_target, closing_velocity) / (to_target_distance * to_target_distance);

        float missle_velocity = rb.linearVelocity.magnitude;
        Vector3 force;
        if(missle_velocity > 0)
        {
            Vector3 linear_velocity_normalized = rb.linearVelocity / missle_velocity;
            Vector3 force_direction = Vector3.Cross(linear_velocity_normalized, angular_velocity_of_los);
            Debug.DrawRay(transform.position, force_direction * 100, Color.red);
            force = N * missle_velocity * force_direction;
        }
        else
        {
            force = Vector3.zero;
            Debug.LogWarning("");
            rb.linearVelocity = transform.forward * speed;
            return;
        }
        float force_magnitude = force.magnitude;
        if (force_magnitude > max_accel)
        {
            force = force * (max_accel / force_magnitude);
        }
        rb.AddForce(force, ForceMode.Acceleration);
    }

I would not be surprised if it didn't work

but it works backwards

nevermind, replacing Vector3.Cross with - Vector3.Cross only at second calculation worked

if I negate both it it doesn't work

I don't understand but okay

[naive pawn]

Vector3 linear_velocity_normalized = rb.linearVelocity / missle_velocity;
.normalized exists btw

[real thunder]

I know... I wonder if it's to save on calculations?

[naive pawn]

i guess, if this is a hot codepath

[real thunder]

I just basically copypasted python code as is

[naive pawn]

the python api mightve not had a .normalized method...

[real thunder]

the author used a library with this method

however he used it sparingly

[naive pawn]

probably your idea is correct then

especially if this is a lib where performance matters a bit more

can't really imagine all the vectors in my head but if i had to guess, it's probably that it needs to be negated, but when you negated both it just ended up at the same value (since one of them depends on the other)

[real thunder]

well the code is "for educational purposes or as a starting point for more complex simulations"
probably went for best he could

I tried to copypaste it double checking triple checking so

either original code not working

or the issue is elsewhere

or I got sloppy ofc

in case anyone interested
https://github.com/alti3/missile-proportional-navigation-python/blob/main/3d_pure_proportional_navigation.py

homing is a rabbithole apparently

[timber tide]

I just use rotatetowards and call it a day

[real thunder]

even if you use rotatetowards, what method do you use to predict target's future position?
what extra heading on top of that?

[timber tide]

why ya need a future position

[real thunder]

to intercept

[timber tide]

but if you do then grab the current transform value, dupe it, then translate it in the forward direction a few meters

[real thunder]

yeah you also need to account the time it takes to fly and at that point target would be even further

[timber tide]

https://docs.unity3d.com/ScriptReference/Matrix4x4.html

translate the matrix towards some velocity value of the target transform

then rotate towards that

[real thunder]

I mean

[timber tide]

or if you want to use transforms, dupe the transform, move it, then destroy the gameobject at end of the frame

[real thunder]

it's annoying to predict the position taking into account missle speed

and travel time

[timber tide]

i mean that's how rigidbody's most basic speculation works

just predict where it's at using the velocity then sweep towards that direction

[real thunder]

I copypasted that without looking into it much

static bool GetInterceptDirection(Vector3 origin, Vector3 targetPosition, float missileSpeed, Vector3 targetVelocity, out Vector3 result)
    {

        var los = origin - targetPosition;
        var distance = los.magnitude;
        var alpha = Vector3.Angle(los, targetVelocity) * Mathf.Deg2Rad;
        var vt = targetVelocity.magnitude;
        var vRatio = vt / missileSpeed;

        //solve the triangle, using cossine law
        if (SolveQuadratic(1 - (vRatio * vRatio), 2 * vRatio * distance * Mathf.Cos(alpha), -distance * distance, out var root1, out var root2) == 0)
        {
            result = Vector3.zero;
            return false;   //no intercept solution possible!
        }

        var interceptVectorMagnitude = Mathf.Max(root1, root2);
        var time = interceptVectorMagnitude / missileSpeed;
        var estimatedPos = targetPosition + targetVelocity * time;
        result = (estimatedPos - origin).normalized;

        return true;
    }

and there is also option to add extra heading by several degrees just in case

...anyway this is way less efficient to hit a dodger and most efficient to hit a standing target

well, or one which just moves in a particular direction

[icy grove]

Hey everyone, I was trying to follow the Unity Essentials pathway and during the Programming Essentials I ran into kind of a stoppage because of the input system. I was following along and this is basically the script they gave me (except the jump part that I added).
How could I make use of the input system to make this type of simple movement? Because I tried to follow the tutorial in #🖱️┃input-system but my controls were messed up (basically, A and D go back and foward, W and S go left and right), could I get some help with this?

    public float speed = 5.0f;
    public float rotationSpeed = 120.0f;
    public float jumpForce = 5.0f;
    private Rigidbody rb; 
    private void Start()
    {
        //normal start
    }

    void FixedUpdate() 
    {
        Vector2 moveInput = Vector2.zero;

        if (Keyboard.current.wKey.isPressed || Keyboard.current.upArrowKey.isPressed)   moveInput.y = 1f;
        if (Keyboard.current.sKey.isPressed || Keyboard.current.downArrowKey.isPressed) moveInput.y = -1f;

        if (Keyboard.current.aKey.isPressed || Keyboard.current.leftArrowKey.isPressed) moveInput.x = -1f;
        if (Keyboard.current.dKey.isPressed || Keyboard.current.rightArrowKey.isPressed)moveInput.x = 1f;

        // Move in facing direction 
        Vector3 movement = transform.forward * moveInput.y * speed * Time.fixedDeltaTime;
        rb.MovePosition(rb.position + movement);

        // Y-axis rotation (invert when going backwards)
        float turnDirection = moveInput.x;
        if (moveInput.y < 0)
            turnDirection = -turnDirection;

        float turn = turnDirection * rotationSpeed * Time.fixedDeltaTime;
        Quaternion turnRotation = Quaternion.Euler(0f, turn, 0f);
        rb.MoveRotation(rb.rotation * turnRotation);
        
        //Added by me to add jump 
        if (Keyboard.current.spaceKey.isPressed)
        {
            rb.AddForce(Vector3.up * jumpForce, ForceMode.VelocityChange);
        }
    }
}

[timber tide]

So what's the problem

[naive pawn]

do some debugging, see where the issue starts - is it wrong from moveInput, or from movement/turnDirection?

[icy grove]

Hum I said it up there, but maybe it was confusing. How can I implement the player movement with the Input System?
The script I provided works fine, I just wanted to understand the Input System properly

[timber tide]

Oh right, A/D is mixed up I see. Reading comprehension

[naive pawn]

my controls were messed up

The script I provided works fine
uh, so which is it

[icy grove]

Ok so I now see that I messed up my explanation, sorry about that. The word limit made me mess it up a bit.
That script I provided up there works fine, it just simply does not make use of the Input System, it's using the Keyboard.current.wKey.isPressed.
This is the simple script that DOES use the Input System:

{
   private Rigidbody rb;
   private float movementX;
   private float movementY;
   public float speed = 1;
 
   void Start()
   {
       rb = GetComponent<Rigidbody>();
   }
 
   private void OnMove(InputValue movementValue)
   {
       Vector2 movementVector = movementValue.Get<Vector2>();
       movementX = movementVector.x;
       movementY = movementVector.y;
   }
  
   void FixedUpdate()
   {
       Vector3 movement = new Vector3(movementX, 0.0f, movementY);
       rb.AddForce(movement * speed);
   }
}```
And in this one, A/D goes back and foward, W/S goes left and right

I wanted to know why that is happening and also, how can use the Input System to add jumping to my player controller

[naive pawn]

check if the composite binding for the Move action is set up correctly

[timber tide]

Kinda confused on what type of game composition this is. You have top-down movement it seems but also a jump button

[naive pawn]

doesn't third person with fixed camera basically also have this control scheme

[icy grove]

This is a prototype from the Unity Essentials course that exists in their website, but yes, it's a third person fixed camera

[timber tide]

oh it's 3D right, sorry too much 2D for me today

[icy grove]

These are my input actions. It's the default one

[naive pawn]

well with the input method you have right now, you'd receive an OnJump message (provided you set the input action up) that you can use to trigger the jump

[timber tide]

Vector3 movement = transform.forward * moveInput.y * speed * Time.fixedDeltaTime;
rb.MovePosition(rb.position + movement);

Should just comment out your code and make sure forward at least works with y

[naive pawn]

alright, that looks correct. have you tried logging your movement vectors? is your rigidbody perhaps just not facing Z+? (AddForce uses global coords)

[real thunder]

silly question but what if your camera is tilted

or something like that

misaligned

[naive pawn]

that code does not use the camera

[icy grove]

I'm sorry Mao, that script is working perfectly fine at the moment. I simply put it there in order to show what I want to achieve with the Input System

[real thunder]

the code does not use the camera but if camera is 90 degrees turned
forward backwards becomes left and right

well, it's not the problem I see

[naive pawn]

i was thinking it would be distinguished by the 'facing' direction of the player, but i guess that actually could be plausible if it's just the default capsule/cube

[icy grove]

So, I have the camera attached to the player. BUT the player is indeed turned 90 degrees in the positve axis

So this could actually be the cause?

[naive pawn]

that would be why then - AddForce, and most physics stuff, uses global coords as previously mentioned

[polar acorn]

If you need it to be visually rotated, I would recommend making the visuals a child object of the actual "Player" object and keep that object's rotation at 0,0,0. Then you can rotate the visuals to align with what unity expects "forward" to be

[timber tide]

I'm confused what's being asked here besides the jump button. Are controls reversed? Then it's probably the z of the transform is rotated

[icy grove]

Then this prompts another question from me. If I don't set the rotation like it is at the moment, the player starts facing in the wrong direction.
Is there a way to rotate the player so that it faces the correct direction and won't mess up the movement system?

[naive pawn]

take the rotation/directions of the object into account when applying forces

eg, using transform.forward/transform.right like you were in the other snippet

[timber tide]

Keep the motor of the character at the top, but visuals as the child if the model isn't imported correctly

[icy grove]

Well, the question I had initially about the controls being reversed has been answered, as well as the jump button with the input system. I'm sorry that it was very confusing from the beginning, that was totally my fault and I'll take it into account when asking stuff in the future

[timber tide]

regardless, always keep visuals child to the motor/controller

[icy grove]

Ok that makes sense. So how would that look for the Input System?

[naive pawn]

exactly the same as it did before

changing input system only changes how you receive input

[icy grove]

Not sure I follow, if I use the Input System, like so:

   {
       Vector2 movementVector = movementValue.Get<Vector2>();
       movementX = movementVector.x;
       movementY = movementVector.y;
   }
  
   void FixedUpdate()
   {
       Vector3 movement = new Vector3(movementX, 0.0f, movementY);
       rb.AddForce(movement * speed);
   } ```
then if my rotation is messed up, it will mess up the movementX and movementY variables right?

[naive pawn]

no, movementX is just if you pressed A or D

that's all it is

[timber tide]

movement x would be in global here

so no matter the rotation you'll always move on the global x axis

[naive pawn]

(and that's because of the usage, not because of how you receive the input)

[icy grove]

Ok, I might be missing something here in respect to how the Input System works.
Just to see if I get it, by adding a Player Input component it makes it so that whenever I perform one of the mapped actions in my Input Actions it will send a message that can be caught, in this case, with the OnMove function in my PlayerController script?

So, if I create an action called Jump, it will send a message that can be captured with an OnJump function?

[naive pawn]

yes

[timber tide]

That's one way you can use it, yeah

[icy grove]

Ok, I guess that makes sense. Although I don't understand why movementVector.y will give me the input of A/D, because in Unity, the Y axis is the vertical one?

[naive pawn]

it doesn't

have you actually checked/verified that?

the issue before was your character being rotated on Y, so local x/z didn't align with global x/z
you expected your character to move relative to local x/z, but physics works on global coords

[icy grove]

AH, here, only movementX is actually getting any type of input then?

[naive pawn]

no

i'm not sure where you're getting these conclusions

[icy grove]

Sorry if these seem like dumb questions, just very new to Unity in general

[naive pawn]

your input is fine

you weren't using the result properly

[icy grove]

So if I wanted to keep that rotation I had initially, I would just need to add a minus to movementX and movementY?

[naive pawn]

no

that would work as a (honestly horrible) bandaid fix if your character was rotated 180°, but it's not

you would use the character's forward direction like you were in the working snippet

i said this 15 minutes ago

[icy grove]

Ah so, I could do for the movement, transform.foward * movementY?

[naive pawn]

yes

[icy grove]

Sorry if I'm just sounding dumb atm, but I just can't wrap my head around the X/Y/Z coordinates here

[naive pawn]

which part exactly? the global coordinates thing?

[icy grove]

Why is it that the movement in Y goes back/forward?

[naive pawn]

the x/y from input is unrelated to the x/y/z of the world

[icy grove]

AH

Ok I get it now, x/y from input is like in a normal 2D graph, with positive Y going forward and negative Y going backwards

And then I need to translate this into the global coordinates of unity

[naive pawn]

the x/y from input just tells you how the input is actuated. joysticks and mice work in 2d, WASD was designed for 2d, so they just have x/y

the unity world is 3d, so x/y/z, with Y being up

if you need to map the input onto the world horizontal plane, you use the input Y as the world Z

[icy grove]

Ok I think I understand very broadly how this will work and I can work with this now

Thank you very much for the patience and the explanations

[brazen river]

Hi

Hi guys

[naive pawn]

this is not a social space , if you have a question just ask

[brazen river]

il2cpp

Hi

[naive pawn]

please don't say just hello in chat

[fickle plume]

@brazen river To follow up the warning that got cut short. There's no talk about hacking or cracking games here.

[icy grove]

Can I just come back to this real quick? What does this mean?

[naive pawn]

Controller
\ Visuals
as the hierarchy

[brazen river]

.ok sorry 😐😞

[icy grove]

Because I have my movement script in the parent, here called Player. Should I put the Player inside a new Parent which takes the script?

[naive pawn]

that's what mao is saying, yeah

[brazen river]

👍👍

[naive pawn]

i don't really do 3d so i don't have firsthand experience with setting this stuff up

[icy grove]

And the camera, should it be attached to the new Parent or stay like it is?

[naive pawn]

the new parent

[brazen river]

Hey guys what game are you making?

Reply pls

[icy grove]

Ok, thank you!

[polar acorn]

Not a social server

[fickle plume]

This is a code channel. Unless you have a specific question about Unity code, don't post off-topic here or anywhere on the server.

[icy grove]

Related to this @timber tide, how can I stick my visuals to my parent, so that the position and rotation of the visual matches that of the inputs I'm giving to the parent?

[timber tide]

ya just need to rotate your visual so it faces the direction of your motor/controller's z+ direction

[icy grove]

Yeah, that part is not hard, what I mean is that now my visual is not moving alongside my parent

[naive pawn]

is it actually in the parent?

[icy grove]

So, if I press W, my camera follows my parent, but the visual just stays behind

[naive pawn]

show the heirarchy

[naive pawn]

have you tried removing the rigidbody from the Player object

[icy grove]

Yeah ok that was it, I was trying to do it but I forgot it was a prefab so I had to alter the prefab first

Thank you

[naive pawn]

you don't have to do that

you can modify the instance and then apply the changes to the prefab

[icy grove]

I couldn't remove the component on the instance

[naive pawn]

weird, you should be able to..

[icy grove]

Ok weird you indeed can, I probably just did not see the option there

[final gazelle]

Heya all. Sorry to waste your time with a simple question, but I'm creating a simple "escape room" game/app that I can use with some students of mine. I learned today that I can play simple audio sources using buttons, so I've been doing minimal code.

Ran intro a problem though. Previously, I saw a YouTube video on how to make menu buttons to change scenes, and felt like I understood it, but today is a different day and I don't seem to understand still. Anyone mind helping me?

My code is as simple as this:

using UnityEngine.SceneManagement;

public class GameMenu : MonoBehaviour
{

    [SerializeField] private string gameScene1;
    [SerializeField] private string gameScene2;
    [SerializeField] private string MainMenuScene;

    public void Play()
    {
        SceneManager.LoadScene(gameScene1);
        SceneManager.LoadScene(gameScene2);
        SceneManager.LoadScene(MainMenuScene);
    }

    public void Quit()
    {
        Application.Quit();
    }
}```

I've made a "MainMenu" object with the script attached. I'm referring to this object on the buttons necessary and have assigned the function "GameMenu.Play", but how do I actually choose which scene is loaded on button click? I feel like I've missed something elementary, but I can't pinpoint. Sorry for the long question to something I have a feeling is very banal.

[wintry quarry]

Why is your code loading three different scenes at once?

how do I actually choose which scene is loaded on button click?
You would need to pass a different scene name into Load Scene for each button

You could do this e.g. by making a function like this:

public void Play(string sceneName) {
  SceneManager.LoadScene(sceneName);
}``` And then you can set the scene name in the inspector when you assign the function to the button on click

[final gazelle]

Ahhhhhhhhhh.... right, that makes sense. It clicked.
Do I need a new script for each button that needs to go to a different scene, then? I thought I was doing something smart (an array...?) so I didn't have to make the same script over and over again for each button.

And you answered my question before even seein it 🙂

Thank you very much, PraetorBlue. I think that fully answers my question and should give me something to experiment with until it works out.

[naive pawn]

also sidenote i'd recommend Eflatun's SceneReferences package, it makes it easier to manage specifying scenes to load ime

[final gazelle]

I'll check it out - thanks!

[brave robin]

One annoying thing I found with [RuntimeInitializeLoadType.AfterSceneLoad] and SceneManagement, is that if I try to access a loaded scene it will fail, saying its not loaded. I have to add a one frame delay for it to work. So AfterSceneLoad doesn't seem to actually trigger after scene load, as not everything is done with loading.

Or it might not like that I have 2 scenes loading at the start. A main scene with logic that is always needed, and a level scene with that level's assets. My attempt to set the main scene as active will fail, with an error saying its not loaded yet.

[sour fulcrum]

you dont have two scenes loading at the start because there is an order

what causes the other scene to load?

[brave robin]

Nothing in script, they're just both in the hierarchy when I hit play

[sour fulcrum]

not quite sure how unity editor handles that

but .AfterSceneLoad is what it says

it might not be after the scene your looking for

[brave robin]

It appears to be random, or in reverse order, as it sees scene 1 as loaded but not scene 0

[sour fulcrum]

yeah no clue

afaik multiple scenes in the hiearchy is purely an editor thing

in the context of a built game there is only 1 first scene that gets loaded

[brave robin]

Ahh, that probably explains it then. So for testing purposes I'll leave the one frame delay in, but the final build won't need it

[sour fulcrum]

have you tried your game built?

[brave robin]

Not this project yet, it's still too bare bones - not enough connective tissue yet to play it as intended

[sour fulcrum]

i'd check if your current setup works at all tbh, but I could be mistaken

[potent portal]

how do i stop this from opening all the time

its insanely annoying

[solar hill]

Is that opening up automatically for you?

[potent portal]

yes

[solar hill]

because i dont think thats default behaviour

for me its always project files that get open

thats it

you sure you dont have any extensions?

[potent portal]

the only extensions i have are C#, C++, Python, Discord RPC, Unity, and some Themes

its more like it opens whenever i open vscode

[solar hill]

i think the c# dev kit does it actually

[potent portal]

sad

[teal viper]

In unity preferences - external tools uncheck all the checkboxes and regenerate project files

[rough granite]

why does c# not like type casting from ValueType here but is fine in this other instance?

[wintry quarry]

Is MeshGroup a struct or a class?

[rough granite]

class

[wintry quarry]

that's why

[rough granite]

is Matrix4x4 a struct?

[wintry quarry]

yes

[rough granite]

oh.. i see ty

do you know how one normally gets the value from a foreach of a dictionary i used to know but after taking a short few month break forgot

[wintry quarry]

depends what you're foreaching over

[rough granite]

static Dictionary<string, MeshGroup> MeshGroups = new Dictionary<string, MeshGroup>();

where i just want the class MeshGroup

[wintry quarry]

foreach (var value in myDict.Values)

foreach (var key in myDict.Keys)

foreach (KeyValuePair<X, Y> pair in myDict)```

[rough granite]

:O thank you

i feel silly now

[swift crag]

you can also do foreach (var (key, value) in myDict))

you can iterate over tuples of key-value pairs!

[rough granite]

sorry what's a tuple?

[acoustic sequoia]

Hey anyone, looking for some help with project settings... been looking through the shadow settings and i can't figure out how to make the shadows sharper? also my 3D objects kinda have the same issue, ex. looking at a cude from a isometric view; the 45 degree edges are 'jagged' i want this to be smooth. maybe the shadows will follow suit if that is fixed but idk

[sour fulcrum]

tuple is a c# feature thats like a mini struct

you can make them just by doing

(int, string) myTup = (0,"hi");

its nice for situations in which your dealing with paired data that isn't neccasarily related to a dict

[wraith sage]

Hello, a small question, do you know why when I press "No function" to select one, the options seen in the other image do not appear, but only "MonoScript -> string name" appears

[slender nymph]

https://unity.huh.how/unity-events/incorrect-assignment

[wraith sage]

It works, thank you

[rough granite]

oh never seen this before

though i assume these only have one instance

[sour fulcrum]

wym

[rough granite]

nvm dw, twas a silly statement

[wraith sage]

The WASD movement can only be done through the Update/FixedUpdate? It is not possible to do it through events so that it does not run in each frame? I found that, but it's still using Update.
https://discussions.unity.com/t/wasd-with-inputsystem/943982/5

[solar hill]

Its done in update because aye its the generally agreed upon best way to do it

events are not good for continuous movement

[wraith sage]

And why the update and not fixedUpdate?

[solar hill]

You should use fixedupdate to handle physics and update to handle the input

if youre using an rb

you can do something like

void Update()
{
    moveInput = moveAction.ReadValue<Vector2>();
}

void FixedUpdate()
{
    rb.MovePosition(...);
}

[grand snow]

lets remember that you want to poll inputs such as jump in Update() but something like WASD can be done in FixedUpdate()

[swift crag]

It doesn't matter so much for joystick-style inputs

Mouse input should not be read in FixedUpdate. It'll only tell you the amount of movement that has happened in that frame.

(so at a very high frame rate, your mouse would slow down: most of the mouse inputs are completely lost)

[wraith sage]

Nice. I also think I understand why in this discussion they did it like in this image I sent. This way you don't have to update the moveInput value in each update frame, but only when the event is executed.
https://discussions.unity.com/t/wasd-with-inputsystem/943982/5

[wraith sage]

I think Inputs like Jump can be done with Player Input event, since it is just pressing a button

[sour fulcrum]

depends on the kinda jump, no?

[wraith sage]

yes

[swift crag]

I find it more intuitive to use callbacks for "impulse" inputs, like jumping, attacking, etc.

[ivory bobcat]

Fix Update by default occurs 50 times per second in the best given scenario. Update can occur more often and will occur at least once each frame. So if you had input for a single frame (button pressed but not held), logic in Fix Update (which might not have occurred that frame) might not behave the way you'd expect it to.

[swift crag]

If you need very tight control over execution order, then you want to manually check the state of the action

[grand snow]

Im fine with either but events are often confusing for beginners

[swift crag]

especially when doing them through PlayerInput, because it's a bit..."magic"

it's hard to tell that you typo'd a method name

[grand snow]

how so?

[swift crag]

(in the "Unity Messages" mode, that is)

[grand snow]

Nah im a get the action and sub to a real event kind of guy

[swift crag]

Oh yeah

That's what I always do

[grand snow]

I avoid magic invoke a function bullshit as much as possible

[swift crag]

(and then i even unsubscribe when the object dies!)

[swift crag]

yeah, it's really fragile and opaque

[swift crag]

I have Domain Reload disabled, so I have to tidy up

otherwise I am haunted by the Ghost of Play Mode Past

[grand snow]

we should unsub anything relating to a mono thats being destroyed

[rough granite]

magic? (only replying cause it's my username, forgive me)

[swift crag]

yeah, it's not just a Domain Reload thing

(it's certainly a good motivator, though :p )

it forces you to clean up after even "singleton" objects, like the player

[grand snow]

I can never turn off domain reload because i like static things too much

[sour fulcrum]

clean up your statics then 😛

[rough granite]

man spent 10 minutes trying to debug why my function wasnt working then realized i had the < in the for loop a > 😭

[wraith sage]

What did I miss, why doesn't it print the message when I move the mouse?

[spare mountain]

#🖱️┃input-system ?

[opaque vine]

Hey, guys I just wanted to ask a question really quick how do teams or people currently track and diagnose build time increases in. Do developers manually review editor logs and compare them when build times increase, or do you use a system to monitor build regressions? Like when builds explode from 50 mins to 2 hrs. Or sum like that

[modern lodge]

is there a way to get a list of all of the variables within a class? or rather, is that ea list of all the animatable binding.propertyName s ?

I'm trying to figure out what all the possible binding.propertyName values are without putting a bunch of keyframes and printing out what type they are 😭

[wintry quarry]

reflection - but generally that's not great to do at runtime. Is this for an editor script or what

[modern lodge]

yea this is an editor script, should i go to #↕️┃editor-extensions ?

ill look more into reflection, thank you!

[wraith sage]

The play input does work, it just doesn't work with the mouse, that's the strange thing.

[supple flume]

What are these stuff
I remember seeing them last year and it took me around an hour to find where I saw it

[mint imp]

Hey guys so in my game when you feel done with a level i want the player to press & hold a certain input for 5 seconds.
Then it would play a little animation and show an overview screen.
While holding the input the player should be vulnerable and unable to do anything

What would be the best way to disable multiple player related scripts during this period of holding the button down.
I dont want player to be able to move, look around, attack, all different scripts.
Looking for a better answer then having all these scripts subscribe to the event I'm calling from the script handling the press & holding input and exiting game code

I have this code that sends this event outward and have it effecting only my movement script right now.

Feel like i could broadcast to the entire object or something?
or maybe a manager that hears the inputs and effects all other scripts through public methods?

oh interesting
My code isnt relevant to the question anyways i guess, just have had people ask for it before

[naive tapir]

   void Update()
    {
        if (Input.GetMouseButtonDown(0))
        {
            Debug.Log ("clicked");

            mouseStartDownPos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
            Debug.Log(mouseStartDownPos);
        }

        if (Input.GetMouseButtonUp(0))
        {
            Debug.Log("click released!");
            mouseDownPos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
            Debug.Log(mouseDownPos);

            Debug.Log("Total Drag Distance Is" + (mouseStartDownPos - mouseDownPos));
        }
    }

The last Debug Log prints fine the first time, but for some reason every other time the coordinates appear as zero, why is this?

[spare mountain]

it's saying your click released pos is the same as your click down pos
you're moving the mouse, right?

[ivory bobcat]

Click and release have the same value so it would be zero if you subtract the two. For example, 1 - 1 = 0.

Also, make sure to remove collapse mode in the console window.

[naive tapir]

Yes, which is weird, they shouldn’t have the same value if it returns the correct number the first time

[frail laurel]

quick question

yk how to fix

[naive tapir]

Uhh What’s the issue

[slender nymph]

1. not a code question
2. don't crosspost
3. don't ping people into your questions
   #📖┃code-of-conduct

[frail laurel]

i didn ping

i need hlp

[naive tapir]

My first bit of advice when asking for help is to at least like say what you need help with

Instead of sending a no context picture of something that gives zero indicator of what the issue is

Also I’d do what the moderator or whoever the other guy is is saying

[spare mountain]

But you're dragging right? Not just clicking?

[naive tapir]

Yeah

That’s the weird part

[spare mountain]

Print screentoworldpoint in mousedown and see if it changes

Sorry

In getmouse

So it's every frame

[naive tapir]

Alr

1 sec

[rough granite]

Lets not ask the same thing in multiple places especially when it isnt related to the channel.
Ps i gave you your answer

[naive tapir]

I think that's already the one being printed if I'm not mistaken,

[spare mountain]

No do it every frame

[rough granite]

Ah you already said this man i suck at reading around messages

[spare mountain]

Just to test

[naive tapir]

If my PC blows up, it was nice knowin ya

[ivory bobcat]

Log the mouse position as well and more information if possible ```cs
void Update()
{
if (Input.GetMouseButtonDown(0))
{
mouseStartDownPos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
Debug.Log($"Mouse Button Down. Screen position: {Input.mousePosition}, World Position: {mouseStartDownPos}");
}

    if (Input.GetMouseButtonUp(0))
    {
        mouseDownPos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
        Debug.Log($"Mouse Button Up. Screen position: {Input.mousePosition}, World Position: {mouseDownPos}");

        Debug.Log($"Total Drag Distance Is {mouseStartDownPos} - {mouseDownPos} = {mouseStartDownPos - mouseDownPos}");
    }
}```

[spare mountain]

If your pc blows up you're running on a potato

[rough granite]

i like potatos

[spare mountain]

Good for eating not for pc

[slender nymph]

this is a perspective camera, isn't it?

https://unity.huh.how/screentoworldpoint

[naive tapir]

yes

[naive tapir]

I'll check this out, thanks!

[ivory bobcat]

||The world position would be where the camera is unless you provide some other value for z||

[naive tapir]

That might be why....

[slender nymph]

that's exactly what is happening, as explained in the link i sent

[naive tapir]

I've been reading it

Thank you all for your help! It's getting late in my timezone, I ought to get going.

Thanks again!

[gaunt cipher]

Is there something that preserves transform values? Like I'm kinda annoyed that Transform is a thing that holds a position a rotation and a scale but if you try to snipe off Transform into a variable you just store a reference to transform. So when I want to preserve something I have to do Vector3 pos = x.transform.position, Quaternion rot = .. and so on

like a struct that contains two vector3s and a quaternion

[sour fulcrum]

you could make that struct

[gaunt cipher]

very true but knowing Unity someone will be like omg, you haven't heard of the TransformInstance class that's half deprecated?!

so I figured I would cover my bases

[wintry quarry]

Matrix4x4 is what you want

[gaunt cipher]

thank you

[wintry quarry]

Use Matrix4x4.TRS to make one from transform position, rotation, and scale

[gaunt cipher]

deadass, thank you

[verbal dome]

Would that be different from transform.localToWorldMatrix?

I guess the scale could be different if sheared or something?

[nova quest]

hi all. has anyone run into this issue with unity before? revert doesnt fix the issue. deleting Usersettings/layouts didnt work. deleting library didnt work.

[midnight plover]

When does this happen? When opening the editor? Do you still have access to the menu to run window -> layouts -> reset or pick one default?

[nova quest]

yes when opening the editor, when it gets to "open scene". i dont see the main unity UI so i cant do window > layouts > reset

[midnight plover]

And when you hit cancel, it just closes the editor?

For future topics, this is not a coding issue, so #💻┃unity-talk would fit better next time 🙂

[nova quest]

yes, same with quit. and revert just opens the popup again. thanks sorry about wrong channel

oh, cancel finishes loading but i dont see the main unity UI, but i can see the menu bar options not greyed out now

[midnight plover]

Did you try to open it with another editor? I guess, there is some broken unity editor files being the cause

[nova quest]

oh that worked, it opened a panel and i was able to add scene to it

[midnight plover]

Oh, so its fixed?

[nova quest]

yes, i clicked cancel and it opened one of my panels but not the main ui, then i went to add tab and added scene, and back to where i was

[midnight plover]

Nice 👍

[nova quest]

it happens every restart, im gonna see if i can do window -> layouts -> reset

[midnight plover]

Yeh, probably reset or just changing to any default layout and save,close, reopen might fix it

[spare vigil]

wondering something before i develop a possibly bad habit

is there any difference between the two? is one recommended over the other if they're the same functionally?

vs

float yValue = Input.GetAxis ("Vertical") * Time.deltaTime * moveSpeed;

[midnight plover]

first habit you could change is using the old input system 😉 Apart from that, the second line is way more readable but you are also missing spaces on your first way to format it more readable

[spare vigil]

oh yeah im just working thru this tutorial and they're using this one for ease sake i guess

i figure they will move onto the new input system later

well beside readability i think what i am mostly concerned with is with the first one the value is being modified in the arguments of the method and the 2nd example they're modifying the value within the variable itself

in my mind changing the value would be done in the method or arguments (?) rather than at the variable level because the variable should just stay what it is until it gets changed by a method

[sour fulcrum]

It's good to get into the habit of thinking about what your doing like this but in this case your overthinking it a little imo

[spare vigil]

yeah im sure hahaha

[plucky peak]

erm, i have a bit of question if anyone has the time

[sour fulcrum]

because the variable should just stay what it is until it gets changed by a method
this bit is a poorly steered conclusion i think

espicially when in the second example it is being changed by a method, the one that code is in 😛

[umbral jetty]

Guys i wanna make 3d platformer with no coding experience at all

i barely know variables, get components, instantiate and other basic stuff

but that is all

[spare vigil]

i guess ultimately it is all within Update()

so maybe i am just looking at it incorrectly

[sour fulcrum]

ah i didn't have that context, yeah ideally you'd probably have that stuff in a seperate function/method and just call it from update

something like MovementUpdate() etc.

[spare vigil]

genuinely that is probably some later step in this tutorial, im just getting ahead of myself

thank you for the responses! gonna get back to it and try not to overthink things

part of it is just me trying to work thru what it is im doing i guess

rather than just following along and not retaining it

[sour fulcrum]

forsure

[midnight plover]

I generally try to go by the rule of reading the code as words. If you still can understand it without going on the same line several times to explain to yourself, whats happening, you got a good base. Of course, you will get into the habit of using linq and expressions to reduce code but they would still be readable and "easy" to understand. But thats something you develop over time. Where it makes sense to reduce code and where to use local variables and what not.

[plucky peak]

im a beginner and im trying to deal with vectors. there is a missile that shoots from a ship, and i want it to go into the direction of where it shoots. however i am having trouble with trying to make my direction accessible across functions. https://hastebin.com/share/nuradicoco.csharp

[midnight plover]

so to understand it correctly. Your missile should just fire in the direction of the ship heading?

[plucky peak]

yeah, im very new, so im not entirely sure what im exactly doing

but im trying to play with vectors and i am assuming that in the direction of the enemy in accordance to the missile position

it would go to that location?

[ivory bobcat]

Normally when you've spawned the projectile, you would set it's direction not long aftercs var bullet = Instantiate(bulletPrefab); bullet.direction = ...;

Assuming direction is public

[plucky peak]

hmmm, but would direction still be the transform.position - enemy.position?

is that how you'd determine a vector?

[ivory bobcat]

Ownership question. Who should direct where to bullet goes?

[midnight plover]

But you updating the direction does not have any effect for now, because your fixedupdate is using the movement vector from Start().

[plucky peak]

player

[midnight plover]

Which should be right, but does make update() useless in that case.

[ivory bobcat]

(Unless it's some sort of heat seeking missile where it ought to adjust itself according to some target)

The shooter would still provide the target in the above case though

[plucky peak]

let me give some more context, the player is able to rotate, not move, but how would you find the data on direction they face? i think i am having trouble on that and attempting to move that infomation towards PlayerMissile

*rotation of player is determined by mouse position

[sour fulcrum]

Transform component contains .forward which is a Vector3 pointing forward

[midnight plover]

Maybe you did not use it yet, but there is also something called vector3.forward, in your case transform.forward, which you could use if you want the missile to just go straight forward from the player. But your current script is trying to seek on the enemy. So you gotta decide here, what you are approaching

[plucky peak]

i think transform.forward is absolutely perfect for my case. im not trying to make a heat-seeking missile, i just want it to shoot from the direction of the player

[midnight plover]

if its shooting in a 90 offset from what you expect, transform.forward is not your actual forward 😉 Just in case, it could also be transform.right if you created a prefab with "mixed up" visual rotation

[ivory bobcat]

2d would be right

[midnight plover]

true. forward is always 0 on z in 2D 😄

[sour fulcrum]

oh btw, regarding this in your code

     //MovePosition expects a Vector2, but I am sending in a Vector3.
        //why am I doing it this way?
        //what is happening when I send it in?
        rb2d.MovePosition(transform.position + movement/1000f);

A lot of things with a Vector2 param will accept a Vector3 and just remake a Vector2 using the 3's x and y

it's just a convience thing

[plucky peak]

gotcha

tysm

another question

would i need to do anything within my playerscript, or can i just do everything within my playermissile? i am able to get information of the player from this script, so i don't think at the time i need anything from my player, right?

[midnight plover]

Thats a very generic question. What is "everything"!? you should not do everything from a missile script that gets destroyed at some point 😄 But if you mean like, you hit an enemy and probably get XP from it, you should use some manager/event system to fire the correct events that need react on this situation.

[plucky peak]

gotcha, i think, i dont need to make anything in the player script, as i just only need position of the player so it should be fine

tysmm guys i appreciate it

ill look into transform.right

[errant breach]

Hello, do i make a mistake ? Because my script cannot access c_EnemyAmount;

My script :

• private ProgressionScript progessionScript;
• progessionScript.c_EnemyAmount += 1;

Crashes the game with the error :

NullReferenceException: Object reference not set to an instance of an object EnemyScript.Activate (System.Single timeBeforeSpawn)

But in another code (from a tutorial), this work just fine.. And i dont understand

Thanks !

[midnight plover]

Null reference always means, the object you are targeting is not there. So where do you set the progressionScript? As its private, you might seem to use a look up somewhere, like getcomponentinchildren or findbytype or whatever

or not at all which would explain it

[errant breach]

Thanks for taking time to explain !
Here is the script, it should be public right ?

By the way, here's my sourcecode :

https://paste.ofcode.org/z4KE5GrHusgQAUmSzgWRLK

As for EnemyScript, the error is caused when i do :

progessionScript.gameProgressions.c_EnemyAmount += 1;

[midnight plover]

you might wanna answer my question 😉

[errant breach]

The progressionScript is on the "Content" object, and i dont use getcomponentinchildren or findbytype or whatever because the tutorial didn't use any so im lost.
Here's how i do it :

private ProgressionScript progessionScript;
progessionScript.gameProgressions.c_EnemyAmount += 1;

[midnight plover]

blindly follow a tutorial is not the best way. in c# language your line just says:

create a "placeholder" for some script with the type ProgressionScript that is only accessible to this class (private). but the actual reference is never assigned, so this line
private ProgressionScript progressionScript;
can be read as
private ProgressionScript progressionScript = null;

So to actually tie it to an object, you gotta assign it with the runtime object in your scene. Either make it public and dragdrop it, or find it once on start/onenable or wahtever you prefer with Getcomponent or FindObjectByType or or

[midnight plover]

Just because the script is in the Scene does not mean, is automatically accessible to any script

Ah, sorry
Is because I'm trying to implements an Interface about Naninovel asset, but the developer never helps
Just send the Unity documentations :/

I'm new with interfaces, then I'm very confuse

still vague

Okay
In a big resume, I got so many errors when I tried to use the interface
But I'm confuse about it

[slender nymph]

you need to implement the methods that the interface declares

that is literally the entire requirement of implementing an interface

[rich adder]

time to go back to basics

does anyone know how to stop getting server tick batching warnings in NFE, been getting em since i made the project lmao

[onyx blaze]

Like everything empty?
But, will not get errors?

[polar acorn]

The IDE can even create the stubs for you

[polar acorn]

Well, actually attempting to run any of those methods will throw a NotImplementedException

[slender nymph]

But, will not get errors?
you're literally throwing exceptions in every single one of those methods

[polar acorn]

Because that's what they contain

If you don't want them to throw exceptions, you should put code in there

[rich adder]

NFE?

[onyx blaze]

Wait, wait, each one are tell a different thing
I'm trying to solve it since weeks :/

[slender nymph]

you need to actually implement a body for the methods

[grand snow]

Ill be nice. Visual studio has filled in default definitions for the required functions. You are expected to do more with these as you can see rn they all throw an exception.

[sour fulcrum]

pls i need my first job

[rich adder]

taking a job / getting as programmer without knowing how interfaces work is wild

[cosmic quail]

probably a scam job that isn't planning to pay him 🤔

[night gate]

what kinda job are u doing that involves unity

plus

being the only programmer

plus the only programmer in years

did they specify they wanted whatever it is to be made in unity 😭

[midnight tree]

Oh my god, my eyes are burning from the toxicity in the chat...

[night gate]

tbf im just curious

[sour fulcrum]

ts just a rough industry

[night gate]

like what kinda company is needing a unity game (specifically one involving complex interfaces and the such) out of the blue and only hiring one programmer

im not saying i dont believe them like it sounds believable it also just sounds odd

[night gate]

ofc ofc

[midnight tree]

I'm about chat at all

[night gate]

ah okie

im surprised no one just

asked what they need an interface for

[night gate]

what exactly are you needing an interface for?

[slender nymph]

they're trying to implement a third party asset that requires the use of it

[night gate]

ah

what asset did they say

[rich adder]

you can literally just scroll up and read it..

Naninovel asset

[onyx blaze]

I'm using Naninovel asset and Ultimate DLC Toolkit
I'm trying to create a custom provider in Naninovel to get the files in the DLC
But to do this, I need to use an interface
But I'm very confuse about how to do this :/

[night gate]

theyre using a paid asset on a one-person unity job after not hiring a programmer for years?!

average management decision tbf

[rich adder]

whats that got to do anything with it...nothing wrong with using a paid asset..

especially if the company foots the bill..

why reinvent the wheel if you have asset doing what you need

[grand snow]

Are you sure you cant just inherit + override an existing implementation? Otherwise it appears like you need to re implement all those loading functions.

[night gate]

im just judging the company

[rich adder]

sorry but have you worked in a company before? pleenty of companies aquire different software for specific needs.. it wastes more money coding everything from scratch and mantaining it..

alas veering offtopic anyway..

[night gate]

fair enough ig

[grand snow]

Its a no brainer to spend like £50 to save a few days work

[slender nymph]

at this point i'm not even sure they need to be implementing the interface theirself rather than just getting an object reference

[grand snow]

Yea im not sure but they seem to think they need a custom provider or something so who knows 🤷‍♂️

nice to see UniTask though

[night gate]

are you sure you need a custom provider?

[onyx blaze]

Yeah, because I need to read the files that are out of the builded game

So I need to create a ResourceProvider that Allows me to read this DLC content

[sour fulcrum]

this hour of troubleshooting in a lot of countries probably costed more in time lol

[grand snow]

Your best bet is to try to use addressables as this supports content outside a build.
Otherwise the only solution is asset bundles manually handled (which is harder vs addressables)

[onyx blaze]

This issue is because, the files need to be inside the ProjectSettings to be readed
But when the game is compiled, ProjectSettings is unacessable

[grand snow]

That does not make sense

[polar acorn]

You implement the interface, and add in the code you want to run on those functions.

[grand snow]

Are you thinking of a project setting scriptable object instance?

[onyx blaze]

That's the issue

I'm trying to understand how to do this ;-;

[sour fulcrum]

Not to derail the direct question but just a kinda vibe check with no disrespect, whatever solution you end up going here is probably gonna take you some time to learn about parts of what needs to happen here

just make sure you have the time budget necessary for that

[polar acorn]

What do you need those functions to do? Whatever asset has the interface probably has some sort of documentation

[grand snow]

Guys its clear they dont really need to do this

They somehow think getting project settings data needs some silly solution. They should just be in a scriptable object somewhere

[polar acorn]

I don't know the asset, so I don't have any context for what it's supposed to be

[grand snow]

TMP for example already does this but their settings are in a scriptable object in Resources

[onyx blaze]

Is because I cannot show the game here
I have a video about this dlc

[slender nymph]

you need to actually provide a proper description of what your goal here is, because right now this really seems like an XY Problem

[onyx blaze]

I have the Naninovel Asset, that is to do Visual novels
This asset uses the ProjectSettings to set the files the will be read, like dialogue scripts, as example

But when compiles the game, ProjectSettings isn't accessible anymore
To this I use a folder "DLC" to add the characters files that I need
Some files as images or sounds works because don't need to be inside the Project settings

[slender nymph]

why can you not configure it before building the game

[onyx blaze]

I use this code to read the DLC files and load in the game

https://pastebin.com/Ma6CCZSj

[onyx blaze]

Because the characters will be release separatedly, as DLC

[slender nymph]

whatever. continue the explanation, and for the love of all that is holy stop breaking the explanation up into multiple messages. it is incredibly fucking annoying to have to read only a small part of the explanation and then wait several minutes for even a crumb of context

[acoustic maple]

I added a tag to a the ball in my pinball game now it falls through the floor

[slender nymph]

trigger colliders do not provide physical collisions

Thanks

How do I wait for an animation to end?

[slender nymph]

use an animation event

[acoustic maple]

Is that code?

Sorry I am new

[slender nymph]

you know you can google things, right?

[queen vale]

Inside of the animator/animation you can add events.

[queen vale]

Select the object containing the animator (0) > select the target animation > create an event (1) > select / place the event marker where it needs to trigger within the animation (2) > select a function within the script attached to the same gameobject, ie your script & function need to both exist on the gameobject that contains the animator (3).

[acoustic maple]

I made the animation in blender how do I do this?

bc the button is grayed out

[queen vale]

Which button?

[acoustic maple]

add event

the animation is read only

[queen vale]

Go to the asset/animation within your "Project" tab, select it.

Ctrl+D to duplicate it.

Make adjustments to the duplicated file

[acoustic maple]

I found it is in the main fbx

[queen vale]

I'm not sure that I understand? What is in the "main" fbx? When you import a model/fbx that was animated within blender, so long as your export settings were correct, it should still carry the animation. When selecting the initial (within Unity/"Project") import file you have options to generate colliders, carry over materials, and import animations.

[acoustic maple]

i got it

[acoustic maple]

I have the code but cant call it. I am getting this error 'bumper' AnimationEvent 'endbumperanimtion' on animation 'Cone|ConeAction' has no receiver! Are you missing a component?

[slender nymph]

do you have a method with that name on a component that is attached to the same gameobject your animator is on?

[acoustic maple]

a method starts with void right?

[slender nymph]

void is a return type for a method, but it is not the only return type. in this case the method you write for the animation event should return void

[acoustic maple]

can you give me an example? I am new to C#. I came from Java

[slender nymph]

there are beginner c# courses pinned in this channel, start there if you don't know how to write a method. but if you came from java then you should already understand what methods are and how to use them, as well as return types.

[solar hill]

Java has void methods too though

[cosmic quail]

it works the exact same in java

c# is basically identical to java in almost every way

[polar acorn]

Return types in C# are known as return types in Java.

The Java equivalent of C#'s void is void

[acoustic maple]

In my basic java class we only used void.

[slender nymph]

then you didn't really "come from java" if you barely even learned the basics

[solar hill]

also what basic class would not teach you the other types??

[sour fulcrum]

a lot of them

[acoustic maple]

Yeah we were told to use void to compress code.

[slender nymph]

that makes literally 0 sense

[sour fulcrum]

your teacher is stupid but thats besides the point

[acoustic maple]

I can do alot in game maker but they use a wierd propritary language.

[acoustic maple]

worded that wrong. use it to organize code

[solar hill]

what

[slender nymph]

still doesn't make sense. you can use methods to modularize and organize code within a class, but that doesn't really have anything to do with the method's return type

[swift sedge]

you use any method to reorganise code, regardless of return type
the return type is only there to take it one step further and actually return some data from a method call

[cosmic quail]

splitting code into methods does help organize it better

[queen vale]

Propriatary, GameMaker uses "GML".

[solar hill]

thats not what i was responding to

but ok

[queen vale]

my bad 😓

[edgy tangle]

I think probably teachers teaching beginners lean into just using void return types because explaining returns just adds more stuff that might confuse beginners

[verbal dome]

I'd say that not understanding return types leads to more confusion

Such a fundamental concept

(I did check GML a bit and the return type seems to be implicit or something https://manual.gamemaker.io/lts/en/GameMaker_Language/GML_Overview/Language_Features/return.htm)

[edgy tangle]

Could be. I remember when I started out I didn’t really get it for a while, but that may also have been due to following tutorials that only really ever used void return types

Just playing devil’s advocate that I could understand why that topic wouldn’t be covered right away

[queen vale]

I'm not formally educated in any of this, are we talking about

public GameObject Get_Menu()
{
  return menu.gameObject;
}

🥲 the sweating face does not give me confidence

[cosmic quail]

that's a head shaking vertically face
(nodding)

[queen vale]

Ahhhhh, need new glasses lol

[cosmic quail]

they were talking about method return types and GameObject is indeed the return type of your example method

[edgy tangle]

Back to @acoustic maple’s problem… yeah you need to have a public void method on a script attached to the same GameObject as the animator with the EXACT same name that you put on the AnimationEvent

I’m not positive if it MUST be a void return signature, but unless there’s a specific signature the animator can use then it won’t do anything with return types anyway

I don’t know how it works under the hood but I assume it’s using SendMessage

[queen vale]

^ Like Owen said, needs to be public.

The event could be linked to

public void DesiredAnimation()
{
  // do things
  gameObject.SetActive(false);
  // etc...
}

Then so long as the animation actually plays and the event is in place. It'll trigger the desired behaviour.

[acoustic maple]

thanks

[queen vale]

As for the no reciever part, you need to make sure that:

• There's an animator component on the gameobject.
• The script with the desired function / behaviour is on that same gameobject.

[swift sedge]

Much like Lua, GML doesn't have explicit type declaration support. It's all dynamically typed. Which is why, for general information, Roblox created and open-sourced Luau to add types, generics, etc. as a derivative of Lua, which makes game dev much easier, and makes code easier to understand with less errors

[acoustic maple]

time to work on geting the bumper to put more force on the ball to be relistic

[floral garden]

Hi, i got an question while following a tuto , with the new input system
he put an input and a getter like

functionInput
// turn true the bool associated with it touch

then a function get
turn it off
and return true
else
false

is it a good way to manager the button ? will it have a data race ?

[verbal dome]

Yeah. Having to read through the method to see what type it returns is beyond me 😅

[swift sedge]

also, Luau goes one step further and supports union types, i.e. (number | string) can either be a number or a string, which I think is so cool

[acoustic maple]

That’s why undertale is so hard to mod

[queen vale]

Not sure what you mean, as for a data race I can't reliably say either.
Code runs from top to bottom (sorta) so if an input is read earlier in the script, it's value/variable with be updated sooner.
As for what will "react" to said input first, depends on the order of functions/calls that operate off of that condition/input.

[grand snow]

any moment

[polar acorn]

I have no idea what you're referring to, if you have a question about a specific function in a tutorial, you should probably actually show it instead of trying to describe it

[wintry quarry]

Can you try rewriting this and maybe give us the actual code? Your description here is really vague and your question about a "data race" is unclear.

[queen vale]

Maybe this'll help (?)

void Test()
{
  Func_B();
  Func_A();
  Func_Test();
}

void Func_Test()
{
  Debug.Log("1");
  Debug.Log("23");
}

void Func_A()
{
  Debug.Log("Hello");
}

void Func_B()
{
  Debug.Log("Goodbye");
}

Output = Goodbye
         Hello
         1
         23

[grand snow]

wasted effort if you ask me

[queen vale]

Only takes a moment, besides procrastinating on my project atm lol

[timber nacelle]

i might be kinda annoying but i just saw a youtube video of a tutorial on how to make a player with movement, but the game is just spamming: "invalidoperationexception: you are trying to read input using the unityengine.input class, but you have switched active handling to input system package in player setting"

i already got 999+ error outputs with the same message lol

[solar hill]

!Input

[radiant void]

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.

[solar hill]

set it to both

[timber nacelle]

what do i do? i have unity since yesterday 😐

so im a pretty big noob...

[timber tide]

Project Settings > Player > Active Input Handling

[grand snow]

basic computer literacy required

[timber nacelle]

yessss it works now, thanks

[verbal dome]

Did you not read the bot message

It says what Mao said

Not gonna get very far if you dont read instructions

[wraith sage]

Isn't it wrong to move the camera at the event instead of updating? To avoid unnecessary executions when the camera is not moved? I ask because they put it in update everywhere, I don't know if it's because it's not recommended to do it the way I did, or because they didn't think about doing it that way. (the camera works without problems)

[floral garden]

Yes wait a sec

        private bool _submitPressed = false;

        public void SubmitPressed(InputAction.CallbackContext context)
        {
            if (context.performed)
            {
                _submitPressed = true;
            }
            else if (context.canceled)
            {
                _submitPressed = false;
            }
        }

        public bool GetSubmitPressed()
        {
            bool result = _submitPressed;
            _submitPressed = false;
            return result;
        }

    // for any of the below 'Get' methods, if we're getting it then we're also using it,
    // which means we should set it to false so that it can't be used again until actually
    // pressed again.

this is the text he putted in the github

[wintry quarry]

It's not clear what the context of this is? This is presumably the listener for an Input Action - but what kind of input action with what kind of bindings?

[wintry quarry]

this is overcomplicated

whatever code is consuming GetSubmitPressed() should just run inside the SubmitPressed input listener.

or should be subscribed to an event fired from there

[white zinc]

does anyone know why this doesnt work? It is suppose to get a random float from 1 to 5: randomValue = UnityEngine.Random.Range(1, 5);

[wintry quarry]

but no there's nothing in here that is a "race" of any kind

[wintry quarry]

you put integer parameters so you're using the integer version of Random which will return 1, 2, 3 or 4 randomly here

[floral garden]

and about the data race as all update is random (i think)
if 2 update use the input, one will be ignored
this is what my question

[floral garden]

oh ? input system has a listener for each input?

or should I create one?

[white zinc]

it doesnt work for 1 to 4 either

I created a public float that should show the value in the inspector but it is always 0

[floral garden]

are you sure you set the value ?

[solar hill]

reread what he said

[floral garden]

log the value then

[solar hill]

randomValue = UnityEngine.Random.Range(1f, 5f);

[white zinc]

ohh yeah that makes sense

[wraith sage]

Just a Delta [mouse]

[wintry quarry]

You already have one

[white zinc]

it still doesnt really work: ```using UnityEngine;
using UnityEngine.UI;

public class BarSliderRotation : MonoBehaviour
{
public FNAFCamera fnafCamera;
public Slider slider;

public float randomValue;

private bool hasTriggered = false;

void Start()
{
    if (slider != null)
    {
        slider.minValue = 0;
        slider.maxValue = 100;
        slider.value = 0;
    }
}

void Update()
{
    if (fnafCamera == null || slider == null) return;

    slider.value = fnafCamera.rotationPoints;

    if (fnafCamera.rotationPoints >= 100f && !hasTriggered)
    {
        randomValue = UnityEngine.Random.Range(1f, 5f);
        hasTriggered = true;
    }

    if (fnafCamera.rotationPoints < 100f && hasTriggered)
    {
        hasTriggered = false;
    }
}

}```

[wintry quarry]

That's what SubmitPressed is

[solar hill]

have you considered its giving 0 because your conditional might not be triggering?

[wintry quarry]

If it's never being anything but 0 then the code is simply not running

[solar hill]

give randomValue a default value like 20

if it shows up as 20, then you know that youre never reaching random.range

[wintry quarry]

Nothing to do with the Range function

[white zinc]

I put public float randomValue = 20f; and in the inspector it shows 0

[solar hill]

did you change the default value in the inspector or the code?

its a public value, the inspector will always override it

[floral garden]

...?
do you mean , I can juste read the value and remove the getter ?

[white zinc]

in the inspector I put 20 now and it stays as 20 the whole time

[solar hill]

right...

so yes your If statement is failing somewhere

most likely your fnafCamera.rotationPoiints

[floral garden]

[queen vale]

using UnityEngine;
using UnityEngine.UI;

public class BarSliderRotation : MonoBehaviour
{
    public FNAFCamera fnafCamera;
    public Slider slider;

    public float randomValue;

    private bool hasTriggered = false;

    void Start()
    {
        if (slider != null)
        {
            slider.minValue = 0;
            slider.maxValue = 100;
            slider.value = 0;
        }
    }

    void Update()
    {
        if (!fnafCamera || !slider) return;

        slider.value = fnafCamera.rotationPoints; // How is this value getting set?
        Debug.Log(fnafCamera.rotationPoints);

        if (fnafCamera.rotationPoints >= 100f && !hasTriggered)
        {
            randomValue = UnityEngine.Random.Range(1f, 5f);
            hasTriggered = true;
        }

        if (fnafCamera.rotationPoints < 100f && hasTriggered)
            hasTriggered = false;
    }
}

[solar hill]

log the value of that at the top of your update

[floral garden]

why don't you toggle debug and place a break point?

[solar hill]

its almost certainly fnafCamera.rotationPoints, my question is whats the point of setting sliders.value to it but then just using the rotationPoints in your if statements anyways

[floral garden]

what the print value of rotationPoints?

[white zinc]

in the console it shows the correct value of rotationPoints

from 0 to 100

and it resets to 0 when reaching 100

[ionic mirage]

hello wonderfull people hope evryone have a great weekend im looking for help right now it been 2 day trying to figure out why my new character dont want to move beofre i had a captuse and move normaly after download character only camara rotate left and right

[floral garden]

2d ? 3d ? Rigidbody or Character controler ? new input system or old ?
keyboard or xbox controler ?

[queen vale]

What we know

• It found the camera & slider.
• The rotation points is updating in value and reaching 100.
• The hasTriggered by default is false, leaving the first if statement possible but not functional.

Is rotationPoints an int or float?

[white zinc]

float

[grand snow]

I am confused what this is even trying to do

[floral garden]

maybe float accuracy ?

[queen vale]

Strike what I said, int/float shouldnt matter..(?)

[ionic mirage]

both in imput

[queen vale]

It's >= so regardless so long as the value is met or exceeded

[solar hill]

maybe its not reaching 100?

maybe its goes to 99 and gets reset to 0

[floral garden]

both ?

[queen vale]

^^^ mod-10 counter

As soon as the 7-segment display reaches 10 it goes back to 0, never displaying 10

[queen vale]

You could be on to something, but then it's an issue of order of operations

[floral garden]

hmm firstly i recommend you to use only one
New or Old
then for the question
from what i see , it is maybe a CC
can you show where you make the move?

[ionic mirage]

already try new and old nothing just the vcamara rotate left and right and jump

do your input work ? have you try to print your input ?

[ionic mirage]

it was working before i download the character

anyways i can do screen share?would be faster?

[floral garden]

yes but does your input work ? I don't think we can do it here for the screen share

[ionic mirage]

how can i check if my imput wwork?

[floral garden]

place a log after the input in your code
