i made a special tag for the obstacles for a reason

#

welp

#

oh i had a question, I have been facing this problem since the second i started scripting in unity

#

it doesnt show me errors in vs nor does it show me option that i can use

#

like Info.(displays info)

I would recommend learning how to use a computer before attempting to make a game on one

Nah I think I got this ty anyway when people find out one guy made a game and he’s still super new to it and the games are amazing. They’re gonna be super surprised. : )

have you ever heard the phrase 'The blind leading the blind' ?

solar orchid
#

No

#

Let me guess you’re gonna explain how I can’t use a PC if I’ve never used

#

and it’s gonna be in someway that looks like it was from a book

#

I mean sounds

#

Like a book

languid spire
#

no, I'm gonna say you have a great deal to learn. So much in fact that you have no idea of the time and effort it's gonna cost you

polar acorn
#

I'm just saying, learn how to use a device before trying to make a game. Game development is not easy and if you're completely baffled by the concept of computers it's going to be needlessly difficult.

#

I'm not sure at what level you'll need to start at but I can be sure that it doesn't start in a game development discord

solar orchid
#

I know how to do the basic things I don’t know why I said I don’t really know but I actually do sorry for the confusion like I know how files work I know how to open games turn the PC off turn the volume up I know how to edit files like I just know the basic stuff

minor whale
#

I hate this so MUCH. You cant change the pivot without ruining your prefab, you cant find the center of a empty, you cant center a pivot even if you change it. so WTF' AM I SUPPOSED TO do if I want to make my prefabed object move back and forth between a given object

#

I clearly cant fucking rely on pivot for the position

polar acorn
#

Make the prefab a child of an empty object, and position it where you'd want the pivot to be. Then move the empty

wintry quarry
#

you cant find the center of a empty
I mean you can but why would you want to

minor whale
#

I have to set the pivot to the center of the game objects

#

and thats not possible without guessing

wintry quarry
#

it just takes the average of the center of all the Renderers of the children

minor whale
#

so I cant find that vector anyway

wintry quarry
#

You can find it

#

I just told you how

polar acorn
naive pawn
#

isn't the "center" of an empty just its position lol

polar acorn
#

It has no extents. It's position is literally all of it. It's the center, the bounds, the extents, the top, the bottom, all of it. It's a point

wintry quarry
#

it's just the average of all the renderer bounds

minor whale
wintry quarry
#

It's not magic

minor whale
polar acorn
wintry quarry
wintry quarry
polar acorn
#

Honestly you should probably not use the "Center" handle position in general.

rocky canyon
#

Pivot fo lyfe!

polar acorn
#

It's misleading and not useful at all for code purposes

minor whale
#

which is one way I was considering doing what I wanted

rocky canyon
#

or u use a empty object to mark the pivot.. and then move the transform to that position

#

uncalculated

polar acorn
#

If you need to change the pivot of something do what I first said and use an empty object and position that

minor whale
minor whale
wintry quarry
polar acorn
# minor whale What?
  1. Create an empty object.
  2. Make your model a child object of the empty.
  3. Position the child such that the empty is at where you want the pivot to be.
  4. Boom you now have a pivot
minor whale
#

also one more issue is that I cant get the width of my game empty object without looping through all the children :0

wintry quarry
#

because "width of a GameObject" doesn't have any real meaning

minor whale
polar acorn
wintry quarry
polar acorn
#

Your issue is that you seem to assume that "this gameobject" means "this gameobject and all of its children" when that isn't the case

#

They're different game objects

#

they just have transforms relative to another object's

minor whale
#

Main issue was getting a prefab object to travel back and forth on a given object and a given axis

#

but then I kinda wanted to rant because everything I tried conveniently unity doesnt let you do without making you do it in a abstract or weird way when it has the features itself that define those already

wintry quarry
polar acorn
minor whale
#

yeah ik D: but it would be easier for me to do lol

polar acorn
#

This is what we call negative reinforcement. It wants you to deal with the pivot using a parent object, so it doesn't provide tools for dealing with pivots in other ways.

#

That way the position of the pivot is plainly visible in the inspector, instead of buried in the asset import settings or some other sub-menu

#

And you can quickly tweak it on the fly, even for different instances of the same prefab

minor whale
wintry quarry
#

then it's basically just:

Transform a, b;

void Update() {
  float duration = 2f;
  transform.position = Vector3.Lerp(a.position, b.position, Mathf.PingPong(Time.time / duration, 1));
}```
minor whale
#

lol

polar acorn
#

You'd put this script on your pivot object

#

then it'll move the object's pivot to exactly the position of a and b

wintry quarry
#

this is all solverd with a few seconds of setup and some small calculations in code

#

Game engines are meant to give you the foundation on which to build your game, they aren't meant to solve every individual problem automatically

minor whale
#

yeah but for a function built into the engine itself it would be nice if it was a feature in the documentation/api

polar acorn
#

Which function?

#

Lerp? Distance? Both are in the documentation

minor whale
#

this functionality on the front end of unity

polar acorn
minor whale
#

I meant the backend documentation

#

for scripting lol

polar acorn
#

Why would an interface feature be in the scripting documentation

#

There's nothing about "Center" mode in the scripting API because there is no such thing as the center mode in code

#

Code deals entirely with the true positions of the transform

#

When you do someObject.position that's getting you the position of the "Pivot" option from the interface, as the documentation I linked says.

rich adder
# minor whale for scripting lol

at most you can get the Center of a collider/ bounding box, but transform.position ALWAYS returns the pivot point center or not

polar acorn
#

"as defined by the Transform component"

what's the consensus regarding using C# event over UnityEvent over Actions?
I expect to have data with my events, but no idea which to pick

polar acorn
#

UnityEvents can be set in the inspector.

That's basically it

winter aspen
#

what about Actions and C# events? (aside from the editor)
is there any reason to pick them?

polar acorn
#

An Action is an event, but with a specific pre-defined delegate

rich adder
#

Action is just a delegate type for event

#

use UnityEvent only when you need the inspector, period.

#

any other times use c# events

winter aspen
rich adder
#

this was done in unity 5.3.1f1 in 2016 , who knows how much is still relevant

winter aspen
#

Thanks

#

guess i'll just stick to C# events then

Hey everyone,

I’m working on a simple 2D game in Unity with a stickman character, where each part of his body (legs, arms, head, torso) has its own rigidbody, allowing for physics-based interaction. I currently have a script that lets me click and drag the stickman around, and he moves and interacts with the physics.

For a while, I was trying to create animations for the stickman to get up and walk, but since the game is heavily physics-based, I thought it would be cool to make the walking physics-driven too, kind of like in games like Totally Accurate Battle Simulator or Stick It To The Stickman.

The only problem is… I’m not the best at coding. So, I’m posting here to ask for advice or ideas on how to approach physics-based walking. If anyone has any tips, knows of any relevant tutorials, or even feels like helping out with the code, that would be awesome.

Thanks a lot!

im invoking an event here after my while loop is over

        TH = GameObject.Find("GameTable(Clone)").GetComponent<TableHandler>();
        TableHandler.MiniGameIsReady += StartMiniGame;

        Debug.Log("called");
        StartCoroutine(LavaTimer());

im subscribing to it here however the function never gets called. TH does get assigned so its not that and the object is instantiated before the event is called so i dont know what it could be
polar acorn
faint osprey

the function is never called

polar acorn

Which function

faint osprey
#

the one im subscribing the event to

#

StartMiniGame

polar acorn
#

Do you get the "woking" log?

faint osprey
#

yup

#

but not called

polar acorn
#

Then it is invoking MiniGameIsReady. Put a log in Start and see what order those happen in.

faint osprey
#

kk

#

ah

#

but thats odd

#

oh cause im instantiating it over the network it does it asynchrously which is why the start gets called after

#

makes sense

so i have this script for a scope overlay for a sniper but i have to issues that i would like help with

  1. When i run the game the overlay starts on instead of off even though its set to false at start

  2. i only want it to work with my sniper curruntly when i press right click on any gun it will run this script and show the overlay on that gun.

playerController.cs (controller in question)
cameraController.cs

  • I have movement relative to the camera.
  • Character is a ball

I want to stop my player from moving when the velocity of an axis falls below a certain threshold (and there is no input), but simply setting "velocity = 0" doesn't completely stop the movement.
In Line 121, using else if for both axes stops the movement after a few fixed updates, but it causes issues with jumping, making the player move along the X and Z axes (this only happens when the camera has been moved).
In Line 141, using else if for both axes stops the player momentarily (as seen only with Debug.Log), but then the player decelerates according to rigid body physics. Additionally, jumping does not affect the X and Z axes, which might be because the last else if is only called "once".

im trying to detect the trigger box collider on my child of my gameobject however neither of the debugs are calling. i do have a mesh collider on the parent gameobject howeever its not trigger so that shouldnt affect it no?

    {
        Debug.Log("collision");
        if (other.gameObject == trackedPlayer && inLava == false)
        {
            Debug.Log("collision with player");
            inLava = true;
            StartCoroutine(DeathTimer());
        }
    }```
rocky canyon
#

else it ignores it.. OnCollisionEnter would be called for a IsTrigger = false object

#

oh u said parent..

faint osprey
rocky canyon
#

does the actual trigger object have a collider?

faint osprey
#

the child has a trigger collider and the parent has a non trigger one

rocky canyon
#

have u tested w/o all the conditionals

faint osprey
#

wdym?

rocky canyon
#

to see if any collider triggers it

#

to see if its a trigger setup issue or its a failed assumption of conditionals

faint osprey
#

ill see

rocky canyon
#

ur Collision debug should fire tho

faint osprey
#

its not

#

even with the parent collider set to false

#

does one of the objects have a rigidbody on them? iirc a trigger requires one

which collides with the colliders

rocky canyon
# faint osprey yes the player has a rigidbody

i was going to ask.. does the parent object that has the child w/ the trigger use a rigidbody?
b/c for OnTrigger to propagate down the hiearchy it'd need one.. edit: (a rigidbody is what links all the colliders together, without one present they're all individual colliders)
if not then the code w/ OnTrigger functions would need to be on the component w/ the trigger collider

Does it ever make sense to have multiple unrelated finite state machines?
Ex: An FSM for player behavior (to handle movement, input game events, etc) and another for the GameManager (to handle level beginning, ending, mid-level events, etc)

Yes, that's how it should always be instead of trying to cram everything into one massive FSM

Hey, I'm making a 2d platformer, but I'm unsure on the movement code, I'm just using some code from a 2d rpg

rb2D.velocity = new Vector2(Input.GetAxisRaw("Horizontal"), Input.GetAxisRaw("Vertical")).normalized * speed * Time.deltaTime;

anim.SetFloat("moveX", rb2D.velocity.x);

how am I supposed to write this?

ivory bobcat

I want it to be specificaly horizontal movement as I don't see any need for vertical movement (apart from jumpuing that I'm yet to learn)

Hello, I'm new to coding and I have a problem with a bit of my code.
I have 2 different methods for 2 different tags, one for when player collides with different objects(tag), and one when he collides with the finish object(tag).
The colliders work fine(as the finish even transfers player to the next scene), but the problem is with the sound
The sound does play when I collide in the "StartCrashSequence" method, but not in the "FinishSequence", and I genuinely dont know why, because unity doesnt give me an error or anything, nor does VSC.
The sound files are present, both of them are working(tested by replacing the crash with the victory and bumping into objects, the sound worked)
what may be the cause for this?

image.png image.png
ivory bobcat
#

Everything would be destroyed if so and thus no sound is played

shadow igloo
ivory bobcat
#

Make sure to save and try again. It should play if you haven't destroyed the scene (load etc)

little meteor
shadow igloo
little meteor
shadow igloo
ivory bobcat
#

Place a log in the function and see if it's logged into the console

shadow igloo
#

the collision works fine, however the audio isnt played. Audiosource is cashed at the start method

#

all other audio(crashing, boosting) works fine, audio for the finish line doesnt work, despite the rest of the code working

astral falcon
#

Just dumb suggestion, the sound is not empty, right?

shadow igloo
#

nope, it is indeed there

astral falcon
#

I mean the audiowave, you can hear it in another applicatino or in unity inspector

ivory bobcat
#

Did you do anything extra after playing the first audio clip? (such as pausing the source)

shadow igloo
shadow igloo
astral falcon
#

Can you debug log your victorysound?

ivory bobcat
#

You've mentioned that a few times but we're unsure what else you're doing

shadow igloo
ivory bobcat
#

Try playing that clip instead of crash initially

shadow igloo
teal viper
#

Can you also share the code with debug logs, so that we know that they're in the right place?

teal viper
ivory bobcat
ivory bobcat
shadow igloo
ivory bobcat
#

So check your audio source before you finish and see if the component is disabled, object inactive, etc

shadow igloo
astral falcon
#

Also check for the audio listener to be active

teal viper
eternal falconBOT
astral falcon
ivory bobcat
#

Did you save the scene? Maybe the reloaded scene doesn't have what you've got set in the inspector for the current edited scene.

#

Assuming reloading is a potential culprit

shadow igloo
#

because if i turn the scene changer again, the next scene will play

ivory bobcat
#

Comment out the invoke on reload and see if things change?

shadow igloo
astral falcon
#

did you check on your audiolistener?

shadow igloo
astral falcon
#

and also check on the volume param of PlayOneShot

ivory bobcat
astral falcon
shadow igloo
astral falcon
#

!code

eternal falconBOT
shadow igloo
#

the finish uses LoadNextLevel which is commented out

ivory bobcat
shadow igloo
random ravine
ivory bobcat
#

Comment out the statements from crash and see if finish operates accordingly - you may need to force the finish to occur. I'm pretty sure if you simply call finish where crash was, it would work so crash has likely done something unintentional. Unless you've got something else going on in between.

ok, i figured out why it was not happening, the tutorial i followed for this project mentioned we could ignore the "GetComponent<Movement>().enabled = false;" for the finish line if we want, so i did that, but that actually interfered with the audiosource playing due to it having an "else" statement that would stop audiosource from playing if the spacebar wasnt playing. Sorry for taking up your time and thank you all for trying to help me with it!

hey, i need help with this stuttering movement. It only happens while moving the camera and moving the character at the same time.
This is the code

        instance = this;
    }

    private float cameraY = 0f;
    void HandleCamera() {
        float mouseX = Input.GetAxis("Mouse X") * sensitivity;
        float mouseY = Input.GetAxis("Mouse Y") * sensitivity;

        cameraY -= mouseY;
        cameraY = Mathf.Clamp(cameraY, -90f, 90f);

        cameraHolder.localRotation = Quaternion.Euler(cameraY, 0f, 0f);

        float vertical = Input.GetAxisRaw("Vertical");

        Vector3 move = transform.forward * vertical + transform.right * horizontal;

what people usually do is move the camera to a position on your character instead of parenting it straight to the physics object, and they also use LateUpdate() for a smooth camera rotation as well.

is there a way i can call my method without this forced parameter. i just want to use it outside of key bindings

slender nymph
#

take out the content of the if statement and put that into its own method. then call that method from within the if statement and from where ever else you wanted to

wintry quarry
#

context? yeah just make another method

echo sand
#

oh i see

steep rose
echo sand
wintry quarry
#

the if statement is not necessary

#

The parameter of course is still necessary because that's the delegate type the event expects.

The callbackcontext contains a lot more information than just the phase of the action

when i switch to the 1st person view it gose to the side i put it the postion of the other camera

At fridt glance, the code looks fine.

Maybe it's different expectations of your inspector values?

Go into playmode first, then set up the offset in the inspector window for both views, make sure they are how you want them to be, test by pressing C.

Changes aren't saved in play mode, so right click the component and choose "copy component"

Then exit playmode, right click it again and choose "paste component values"

Hey, im about to start working on my new game, its gonna be a wow like third person fantasy game. Last time i did this i went with HDRP render and physics etc, i put the bar a bit to high, this time im going with URP and low poly stuff. Before i start with the player id love some input or ideas on what to go with gravity wise, physics or addforce. If i understand it correctly, physics can overcomplicate things, and very few games need it.

cosmic dagger
terse oar
#

oh then im mixing it up, i remember u could go with 2 different paths

cosmic dagger
#

maniuplating the transform or using physics . . .

terse oar
#

ah yes thats prolly what i was thinking about

#

i got pretty far on my last game but ended up in a very nasty problem with going downhill

#

i tried using raycasts and all sorts of stuff to detect the ground but it was a nightmare

#

was hoping there was an easier way

#

i should add that i cant code at all, i understand a few basics, learning as i go watching tutorials then having AI tell me what everythign does to understand it, so maybe its not that complicated to someone who knows what hes doing :p

cosmic dagger
#

detecting the ground is relatively easy. if you don't know coding i suggest learning C# basics, and following the unity beginner and intermediate programming pathways . . .

terse oar
#

im trying to stay away from premade stuff such as the game creator asset, i feel like making them urself even though if its together with a tutorial and AI it feels like its easier to expand it later on, not sure if im wrong

Hey guys what's up...?

#

I know this might be a random question

#

But how would acceleration and friction work in Unity...?

#

I tried finding some tutorials, but strangely enough there's not a lot of tutorials that cover that topic

#

This is what I have so far, and...it doesn't work

languid spire
#

Firstly, please type in full sentences. Secondly exactly the same as irl using a Physics Material

normal turret
#

Oh so I just have to add a Physics Material to my RigidBody2D for the friction...?

#

What about for the acceleration, is it the same thing...?

languid spire
#

you have to create one and then add it, yes

#

acceleration is a mode of adding force, just like irl

normal turret

Ok nice, I'll try that out, thank you

Im trying to do a tutorial someone is showing and they do myRigidbody.velocity but i cant find a .velocity

Unity 6 uses linearVelocity

he uses .up tho and i dont see an option

being new does not mean you don't have to read what the tutorial shows. there is no linearVelocity.up

i'm sure your tutorial, no matter how old, did not do that

coarse knoll
slender nymph
#

yes, now read that

coarse knoll
#

theres a possible chance

#

possible

#

that i put a . instead of =

polar acorn
#

Just use linearVelocity instead of velocity

coarse knoll
#

mb

#

also

#

when should i be putting a ; at the end of a line

languid spire
#

I think you need to learn some C# basics

coarse knoll
#

thats what im doing rn

#

slender nymph
#

you're skipping the "learning c#" part and trying to go straight to the "learning how to use unity" part

coarse knoll

languid spire
#

do you know when to use a full stop in a sentence?

coarse knoll

You should seriously consider learning the basic concepts of C# before you start using Unity alongside it

Doesn't take much to search&replace across a codebase then fix the rest 🤷‍♂️ And if you don't need a new feature, then don't upgrade anyway.

It's weird that velocity got, like, instantly axed as soon as it was replaced, but renderer, collider, etc. existed for like fifteen years without actually functioning

Can anyone see what/if I'm doing wrong with this collision script please? I'm very confused.

Asteroid Tag is correct, asteroiud object is assigned the correct tag. The actual collision(s) work (ship hits the asteroid and stops etc), but the OnCollisionEnter isn't firing at all. Ship Root object has a Rigidbody, no rigidbody on Asteroids and necessary colliders are set as colliders (Not Triggers)

private void OnCollisionEnter(Collision collision)
{
    Debug.Log("Hit");
    if (collision.gameObject.CompareTag("Asteroid"))
    {
        
        shieldMaterial.SetFloat("_Alpha_Level", 1);
        StartCoroutine(ShieldFade());
    }
}

Are you using cinemachine camera?

#

Your player is being moved in fixed update but the cinemachine camera is probably set to smart update or some thing

#

Set your cinemachine camera to fixed update

ruby python
#

Ship root (with RigidBody) (Box collider is for something else)

grave bluff
#

Ok but what about update method that’s still on smart update

#

What happens if you set update method to fixed update

polar acorn
ruby python
#

Asteroid

image.png
#

The Shield Segment has the code/script applied.

grave bluff
#

Are all your cinemachine framing stuff set to default

polar acorn
# ruby python Asteroid

So, this is a third different object. Which of the two you've shown before is the one colliding with this object?

ruby python
#

First one I showed is the Shield Segment object (I have 4 of them, only testing with one at the moment).

grave bluff
#

Yea I think it’s in the brain

ruby python
#

Second one I showed is the 'Ship Root'

grave bluff
#

You know how you can set the damping and offset and all that stuff

ruby python
#

3rd is the asteroid.

zenith cypress
polar acorn
#

Which two are the objects that are actually relevant to this collision? The one with the code on it, and the one that's touching it

ruby python
#

Just to show that the ship has a rigidbody

grave bluff
#

Ok new idea what if you set the update method to late update

ruby python
#

Okay.

Shield Segment, which has the collision code attached.

image.png
#

Asteroid Object

image.png
grave bluff
#

Just update method

#

Man

polar acorn
grave bluff
#

Is it just the background that’s jittery and the player is perfectly fine and in frame

ruby python
grave bluff
#

Is the background static or moving as well

#

That’s weird

#

Ok I’ll see

polar acorn
# ruby python Shield Segment has the code.

Ah, okay. That would be the problem. The Rigidbody calls the function on itself, and the object it hits. So, even though this object's collider is part of the rigidbody, it won't actually send a message down to this object. It's detecting the collision, but it's not getting the function call.

zenith cypress
#

Collision events have to be on the rigidbody yeah ^

#

Had to verify locally since I always forget if that is the case lol

polar acorn
zenith cypress
#

Yeah

ruby python
#

Right okay. I get ya. I was reaaaaaaaaaaaaaaaaaaaaaaally trying to avoid having rigidbodies on the asteroid.s 😕

edgy prism
#

!code

eternal falconBOT
ruby python
#

I guess it would be more efficient to add rigidbodies to the shield segments and set them to kinematic?

polar acorn
#

You could have the Asteroid check if the thing it collided with has the ShieldController script, and if it does, call a function on it that does what you need it to do

ruby python
#

Right okay. Yeah I think that would make more sense.

#

Thank you 🙂

#

This might be a really stupid question, but in terms of referencing other scripts on different objects etc. When it starts to get to be a lot, how do people keep track of all the 'cross referencing' ? I try to avoid it as much as humanly possible cause it gets really confusing after a while. lol.

zenith cypress
#

Could also have the event on the Player's rigidbody, get the contact point, check if it has the shield collider in the contact point, then pass the same collision to a function on your shield to do the same logic you have now.

edgy prism

Hello I am working on a project with projectile spawns and I am currently spawning them probably pretty poorly, my problem comes when I go to destroy my projectiles, if I do so before the coroutine that handles their logic finishes I get missing reference errors but I'm not really sure of the best way to deal with that.

Heres an example of one of my coroutines
https://hatebin.com/qcvwscppna

dim yew
#

how would you go about interpolating the color of a sprite renderer so it becomes invisible after a set period of time?

#

i'm thinking slerp would be the best way but i really cannot figure out lerping

rich adder
dim yew
#

coroutines notlikethis

#

alright thanks

naive pawn
#

you would lerp from 1/255/100 to 0 on the alpha channel

zenith cypress
rich adder
edgy prism
#

Dotween can be super useful for stuff like that if you want to lerp the alpha a specific way too

dim yew
#

i guess i just need to do more research on lerping also

zenith cypress
#

It's basically the modern dotween, highly recommend it (I use it in all my projects)

winter echo
dim yew
#

i'm not familiar with dotween actually

#

so i have some reading to do

rich adder
#

its very good tween library

#

incase you want to use just lerp/coroutine

IEnumerator LerpAlpha(float target, float duration)
{
    float t = 0;
    var startcolAlpha = spriteRenderer.color.a;
    var col = spriteRenderer.color;
    while (t < duration)
    {
        col.a = Mathf.Lerp(startcolAlpha, target, t / duration  );
        spriteRenderer.color = col;
        t += Time.deltaTime;
        yield return null;
    }
    col.a = target;
    spriteRenderer.color = col;
    //done
}```

Hello! I have a question regarding velocity of rigidbodies. I currently have a script that controlls the player with force mode VelocityChange. However when changing direction it feels kind of awkward and almost missaligned from where I want to turn towards. I know why this is happening but I'm confused about how I should counteract the force being applied in one direction when I change to another direction. This is my code and the important details for the player prefab: https://pastie.io/tkrjbw.cs

rocky canyon
#

cancel out all ur velocity and then apply the other direction

noble lark
#

Yes, thats what I tried doing but what I'm mostly confused about is when I should do this. The direction vector is not cooperating the way I thought it would. It's a silly problem really

Hey 🙂

I need a code review, I don't know if this is the best way to do it so I'd rather have an opinion
Im creating an Objective system, like a Quest system, but im pretty sure im using a bad way to do this

My current problem is i need to access the CircuitBreaker instance from the CircuitBreakerObjective to know if the objective is completed
So at the start of the game, i need to get all GameObject's in the scene that have a derived Objective component and register them randomly as an Objective to complete

CircuitBreaker and CircuitBreakerObjective are added on the same GameObject

There is a better way to do that ?

public class CircuitBreaker : MonoBehaviour, IRepairable, IInteractable
{
    // Logic ...
}

[RequireComponent(typeof(CircuitBreaker))]
public class CircuitBreakerObjective : Objective
{
    private CircuitBreaker _circuitBreaker = null!;

    private void Start()
    {
        _circuitBreaker = GetComponent<CircuitBreaker>();
    }

    public override bool IsCompleted()
    {
        if (Info is not CircuitBreakerObjectiveInfo info) 
            return false;
        
        return _circuitBreaker.IsOn == info.MustBeOn;
    }

    public override bool IsFailed()
    {
        // TODO - Add circuit breaker failure
        throw new System.NotImplementedException();
    }
}

Objective:

public abstract class Objective : MonoBehaviour
{
    [field: SerializeField] public ObjectiveInfo Info { get; private set; } = null!;
    [field: SerializeField] public ObjectiveState State { get; private set; }

    public PlayerPawn Owner { get; private set; } = null!;
    
    public abstract bool IsCompleted();
    public abstract bool IsFailed();
    
    public void MarkAsCompleted()
    {
        State = ObjectiveState.Completed;
    }
    
    public void MarkAsFailed()
    {
        State = ObjectiveState.Failed;
    }
}

I solved my problem but I was wondering if there is a better recommended approach to solving this problem or if this is fine? I was having trouble with changing directions smoothly using VelocityChange force mode. This is the code: https://pastie.io/rccjfk.cs

making the rigidbody interpolated will stop the blur probably

#

i think the pixel snapping isnt helping

#

How do I know which colliders are colliding for a humanoid gameobject?

vestal adder
#

try removing that and the code for it and see what its like

#

You dont want to do all your logic in fixed update, only the rigidbody stuff

vestal adder

#

No, I'm just asking you to test it basically

#

See if that works then we can go from there because we know where the issue is

dusty shell
stuck field
#

Comment out your FixedUpdate and put rb.transform.Position = Vector2.Lerp

#

inside update

#

under movement

#

Well, Vector2.Lerp smoothly moves from one Vector2 to another

#

So you need the target position to move to, rather than movement

#

No, Vector2.Lerp(CurrentPos, TargetPos, moveSpeed)

#

Current pos would be rb.transform.position

#

Target pos would be wherever you are trying to move to

#

no, rb.transform.position

#

or if rb is on the transform

#

then do transform.position =

rocky canyon
stuck field
#

Yeah look at that might help

rocky canyon
#

you shouldnt include the thing ur lerping into the lerp..

#

it'll not work right..

vestal adder
#

did you go to your pixel perfect camera and turn off pixel snapping

#

yes if pixel snapping is on it will be jittery

#

i just tested it with my own pixel game

rocky canyon

gotta make the player move the distance the camera snaps/travels for it to look smooth

i think his collision code is on the humanoid

dusty shell

#

ill give you my player movement then you will be able to tell if its the code

dusty shell
rocky canyon
#

not sure how u could tell which collider collides

#

unless u have code on each one

#

or ur collision gets flipped and the thing its colliding with is the thing detecting the collision

#

then u could ask what other. is

#

and that'd be the collider of ur humanoid that di dit

dusty shell
#

I have seen some ways but i just wanted to know if i could get which collider is colliding

rocky canyon
#

put the grounded code on the feet specifically? loll

rocky canyon
#

same issue comes up w/ regular composite colliders (one rigidbody and multiple colliders as children)

#

the only good way is to run code on each collider, or have something else check

#

theres dozens of Unity Discussion posts about it

#

so they can see it changing in the inspector ofc

vestal adder

its just an oversight

#

it can be private

i like velocity it feels smooth

velocity always better than movepos imo

#

when dealing w/ physics.. do it right ykno?

vestal adder
#

mine is topdown

rocky canyon
#

see if it works for you.. tryitandsee

#

ur only normalizing part of ur vector

#

then u add a (non)normalized part of it back to it

#

this is not normalized.. u only temporarily grab a normalized version of input there at the beginning

0C85393D-0266-426D-9F29-A5472959F14F.png

you should probably change the whole variable before using it..

        // player input stored in input variable
        input.x = Input.GetAxisRaw("Horizontal");
        input.y = Input.GetAxisRaw("Vertical");

        input = input.normalized;

    }```

why not normalize it after u get it??

#

and then u can just use input and input.x or y

both would be normalized...

#

i told u why..

#

if u dont normalize the entire variable u should do
rb.velocity = input.normalized + new Vector2(input.normalized.x, input.normalized.y) * moveSpeed;

#

yea..

#

does it still move diagonally faster?

#

well. i wasn't talkin about the jitter.. i just noticed that bad normalization

#

not sure how to fix ur jitter issue

#

its in fixed update..

#

it should be consistent

#

maybe its the pixel / camera stuff

#

i dont know about any of that unfortunately 🍀

#

if the background is snapping it makes sense in my head..

#

so the background and player would snap together

#

then it'd look smooth.. (atleast the background wouldnt jitter against the player) then again idk

in the new input system, how can i make it so instead of it just snapping to -1 and 1, to gradually increase and decrease like in the old system?

i'm having an issues appending data to an array, there's an error:
Assets/Scripts/CubeManager.cs(31,24): error CS1061: 'Cube[]' does not contain a definition for 'Add' and no accessible extension method 'Add' accepting a first argument of type 'Cube[]' could be found (are you missing a using directive or an assembly reference?)
Here's the code:

file.Cubes.Add(new Cube(cube.name, cube.transform.position, cube.transform.rotation));

here's where file.Cubes is defined:

[Serializable] public class Cube {
    public string CubeName;
    public Vector3 Position;
    public Vector3 Rotation;
}

They are of a fixed size

If you want a data structure that can be appended to, you want a List

how can i manage to sort the list in the correct order?

image.png
#

i tried
previewSpriteList.Sort((a, b) => a.name.CompareTo(b.name));
and
previewObjectList.OrderBy(g => g.ID);

#

does nothing

#

the sprites are loaded from resources folder already in this binary sorting

burnt vapor
#

What is the thing to sort? Share your !code

eternal falconBOT
burnt vapor
#

Considering sorting depends on complexity and types in general there's no answer to give until you tell us what it is you want, and what you work with

wooden sandal
burnt vapor
#

That's still too vague

#

What sprites? Show their names, show the folder itself

wooden sandal
#

they are called level 1 to level 11

burnt vapor
#

Show how you currently load them

#

Show code

#

If you want to sort by name, I suggest you try to parse the level number and then sort numerically

#

Hardcode a check that gets the 6 and 7th number and then parse these as an integer. Make sure to check the length. Then keep track of the names and sort based on the number

elder fern
burnt vapor
#

Or don't make it complicated and figure out the number of sprites you are going to display

sleek narwhal
#

I am using this code in to check the collision between two physics bodies, but it's not printing to the terminal when they collide void OnCollisionEnter(Collision collision) { UnityEngine.Debug.Log("Entered collision with " + collision.gameObject.name); }

burnt vapor
#

If you have level 1 to level 11, then you have 11 sprites. Then just use a regular for-loop using this length

teal viper
#

At least not the object that has this method.

echo sand

public interface Interactable

    public void Interact(Player Player);
    public virtual string GetHoverText(Player Player) { return "Use"; }

is it possible to override "GetHoverText" in my interface,
i want the default return to be "use" unless i want to use custom logic and return other strings

teal viper
#

You don't need virtual keyword though. Interfaces are not classes.

echo sand
#

lol i asked chatgpt

burnt vapor
teal viper
#

Ah, perhaps that feature(default interface implementation )is not supported in unity yet.

burnt vapor
#

If you want this, use an abstract class

#

Modern C# has support for base implementations, but not like this

#

And especially not in Unity

Or maybe call it IHoverMessageProvider since you will still show a hover message, but it provides a custom message

Hello, I was wondering why the direction is not properly updating when trying to move my character. I take my direction from a center point on my character (i grab the forward and right vector of the characters transform). This is the code: https://pastie.io/jbeyls.cs

#

I tried to get help with this yesterday but the response was lacking

native temple
#

not to backseat moderate but I don't think it's appreciated to post the same question across all three code channels c:

burnt vapor
#

It's not, that's not the purpose of the channels

noble lark
#

Is pastie io frowned upon on this server, is that why almost everybody ignores the question?

native temple
#

how does your camera follow the player at the moment?

burnt vapor
slender nymph
#

9 times out of 10 it's caused by the camera's movement

noble lark
#

thats why i asked

#

ill stay away from pastie and use code blocks instead until i know

burnt vapor
#

Hard to give an answer when you share a whole class without a direct indication on where one should look

noble lark
#

that was just a test to see if it was gonna get ignored again

burnt vapor
#

What is relevant where? Where is the code that fails? Got a video perhaps?

#

So you don't need help?

noble lark
#

I do, ill repost the message i sent yesterday then

native temple
#

how are you ensuring this?

#

is your camera a child object of the player? is the camera setting its position in Update? In FixedUpdate? is the camera following with smoothing? is it a standard unity camera or a more complicated camera rig?

#

is your game physics heavy?

shrewd oak
#

i need help with my passport game pls

slender nymph
eternal falconBOT
native temple
#

then the easiest solution for now would be to change FixedUpdate to Update and use Time.deltaTime instead

wintry quarry
#

MovePosition doesn't belong in Update

#

really for a dynamic body you should use velocity

#

velocity

#

not MovePosition

#

rb.velocity = movement * moveSpeed;

native temple
wintry quarry
#

Although it's possible I'm confusing how 3D works with 2D

shrewd oak
#

tbh i would ask chatgpt

native temple
#

the jittering happens because physics framerate is at 50 fps by default, while rendering framerates are usually unlocked, or vsynced at 60

shrewd oak
#

skibidi cap

native temple
#

the lazy solution is to increase your physics framerate, but that will hide your issue rather than fix it

#

yeah

#

set it to 0.01 and you probably won't notice issues

#

0.02 is 50 fps, 0.01 is 100 fps

#

if your monitor refresh rate is higher than 60Hz then you might still see the jitter

#

(hence it would mostly hide the issue and not fix it)

#

so, in theory, as long as the rigidbody is set to interpolate, cameras following it should be able to smoothly follow, so that's one more thing to check

#

(might not mean it does so in practice)

#

another solution is to smooth the camera movement, which can also help reduce the issue a little bit

noble lark
#

Hello! I have a question regarding velocity of rigidbodies. I currently have a script that controlls the player with force mode VelocityChange. However when changing direction it feels kind of awkward and almost missaligned from where I want to turn towards. I know why this is happening but I'm confused about how I should counteract the force being applied in one direction when I change to another direction. Another problem that might or might not be related is that the code works perfectly when i look down as much as possible. This is my code and the important details for the player prefab: https://pastie.io/swoycv.cs

Hopefully this uestion doesn't sound like a bunch of random words (I tried)

I want to make the player similar to Human Fall Flat but I'm not sure how. (Human Fall Flat is on the image)

  • What I want:
    1 - I want the player camera to be in 3rd person (just like in human fall flat).
    2 - The player character to be able to rotate from vector y to x or z
    3 - In 2 I want the player character to aim for the straight position by forces

  • uestions of implementing:
    How can I make the player camera be in 3rd person (I want the camera to be in the back and just like in Human Fall Flat 15 degrees down)
    How can I make the player to aim up on y vector? (while writing I understood I can PROBABLY just apply constant forces up on y vector on the player's head but currently as a first step I'm having problems with making the player to be in 3rd person because I can't do it by messing around.)

Code that I currently have for movement:
PlayerMovement: https://hatebin.com/nbbmviywid
PlayerCam & MoveCamera: https://hatebin.com/kdermrhkac

Edit: ok somehow I got it to be 3rd person rn, apparently I didn't mess around enough

human fall flat does not use traditional movement techniques, it uses an active ragdoll which is modified to use forces to "tug" limbs in a certain direction giving it the stylistic feel instead of physical animations. The balance is achieved by locking the rotation of the hips so it cannot fall down, if you would like it to fall down you would need to implement your own balancing system which compromises of setting the rotation of the hips to match a certain angle, then apply logic if you want it to fall down like a ragdoll. Third person is self explanatory, rotate a camera pivot to achieve a Third person effect, or you can use cinemachine which I heard most people recommend.
Here is a guide on a traditional active ragdoll, which contains the basic premise of one.

There is no 4th parameter. When you have a question like that, you should be looking at the docs

slerp and lerp are used differently how again?

slerp is for directions, lerp is for positions

Guys i want to add multiple instances of a prefab Button through c# but i don't know how to set it as a child of canvas

frosty hound
#

The Instantiate function takes in a parameter for the parent

wintry quarry
willow scroll
wintry quarry
#

it will mess up all the layout

#

Instantiate(myPrefab, theContainerTransform) is the best way

willow scroll
wintry quarry
#

because it does

#

because you instantiate it without a parent

#

and the RectTransform gets sad

willow scroll
#

I don't see how it's different from the Instantiate method, since they probably work similarly

wintry quarry
#

You might not see it, but it is different

#

I'm speaking from experience here

zenith cypress
#

Without a parent it gets created where the prefab is, so it can just be "somewhere". Plus without being under a canvas, it won't even render. Then if you parent after that, it can still be in the void somewhere and you still can't see it.

polar acorn
willow scroll
polar acorn
# willow scroll Why would it mess the layout?

Because it will set things like .position after the rect transform has been created, which will break the objects anchors and potentially cause it to have completely inaccurate values.

Setting the parent in Instantiate sets the position first, then the rect transform initializes and converts those values into rect space

zenith cypress
#

Not possibly, you will. Or its data will just be wrong. Instantiating with a parent already handles all that for you.

willow scroll
#

It may cause a bit more issues when moving the object from the world to UI, space, but if it's already inside of the same Canvas, there shouldn't be any issues

polar acorn
willow scroll
#

And, surely, if at some point the object's parent is supposed to be reassigned, you shouldn't reinstantiate it, additionally, given the instance has already been modified

willow scroll
polar acorn
#

You can fix it after calling SetParent by modifying the text transform, but at that point you might as well just Instantiate it directly as a child so the prefabs default values can be used.

If you open a prefab of a UI element, you can even see a phantom "canvas" parent that the prefab just assumes will be there when you spawn it

This is a little vague, but I have a robot arm, with a couple 2 bone IK's on it, and a scripted controllable target, so I can basically direct where the arm goes. But if I build my level geometry around the arm and want to use it to move objects around the arm and the attached objects clip through the level geometry. (the "carried" objects are set to kinematic while they're parented to the arm). How should I fix it? (I basically have the same "problem", but less noticable, when my player character carries objects: they're parented and set to kinematic, so a carried box is freely clipping through the level and other objects)

silk night
#

should stop the arm from moving further if your box or whatever hits an obstacle

quaint flicker
rich adder
noble lark
silk night
#

otherwise you can just change the .velocity for immediate direction change

#

otherwise you can counteract the described effect by first applying a force in the opposite direction of your movement with like 80% of power needed stop it and then apply the new direction, it doesnt break out as much tne

vestal adder

i dont think fixing a faulty movement system by adding an opposite fault is a good idea

you just write with C# syntax

all you have is Unity Specific classes / functions which is the API. If you can read any c# api you can read unity

for other specific unity concepts like GameObjects and their Monobehavior look up the manual or docs. Also check pins in this channel they have good mix of both

rich adder

there are lot of things going on in those images

#

interfaces?

#

the example shown is telling you what its doing more or less, if you want multiple classes to have the same function, for example Damage. You just implement that interface

#

Now you can just look for IAttackable and not care if its a player or enemy cause they have the same function , each handles it their own way, hence "Implements interface" term is used, you are forced to use the method if the class implements the interface

you outta look this stuff up tbh

Since they did not responded in #archived-networking (I waited a few days before asking here) I’m asking here: So i have a problem with my project: Basically when i spawn ONLY the host no warnings appears in the console, but when i try to spawn another player, it gives me continues warning about the rigidbody being kinematic (which it isn't in both rigidbodys), here my script for movement, for reference: https://paste.ofcode.org/pM6H2nvu8P9gzTxERxPhy5

Only when spawning the client in (with the host)
