but thats getting complex i suppose

#

too many abstractions

modest dust
#

Damn, one schools teaches fun stuff like Unity, another one teaches using prehistoric systems and office

#

I guess I'm somewhere in the middle

formal escarp
#

anyways, brb

rich adder
#

im talking 2008

modest dust
#

Makes sense

formal escarp
#

i have a question and i need you guys to be brutally honest

rich adder
#

thats my forte

formal escarp
#

Is it wrong that sometimes, when im desperate i ask .ai for help or to explain me things?

#

(code speaking)

swift crag
#

I do not think it's a good idea.

rich adder
#

agreed

swift crag
#

You'll get plausible looking answers

rich adder
#

it can do more harm than good without you knowing it because of this ^

swift crag
#

but this doesn't mean you'll get valid answers

#

people with experience can notice this, but you're asking because you don't have experience!

rich adder
#

It can give you correct info , the problem is you have to tell when it is and when its not

timber tide
#

it's good for general c# questions but asking it to write you a script of game logic is not

formal escarp
timber tide
#

(it's more trained on some documentations than others and it doesn't seem to be for unity)

rich adder
#

no you should back up what you found out by simple internet search

modest dust
rich adder
#

and see if it matches what you read on AI

My experience for using it with unity is it grabbing the first stackoverflow post and posting that answer

is there a builtin function for flipping sprites vertically?

You made it sound like the web was dead 💀

rich adder
#

nah i was jk, because before AI everyone knew you go to StackOverflow 😛

#

the name itself gives it away what its for

#

A beginner won't know what those three words together are ;p

rich adder
#

thast true xD 😭

autumn tusk
rich adder
#

if you get a Stack Overflow in unity You done fdup heavvy somehow 😆

autumn tusk
#

my sprite is a rigidbody2d

#

actually i should change it to a sprite

formal escarp
autumn tusk
#

dont need it colliding

buoyant knot
#

sprite and rigidbody2D are two totally different things

rich adder
#

I hate flipping in 2D because the pivot is still wrong direction

formal escarp
#

StackOverFlow, i think i have heard of it before but i dont know that that is.

rich adder
#

I just rotate the object 180 on Y

#

since unity is 3D

#

this way my transform.right is always correct

buoyant knot
#

flipping in 2D is very easy. But I usually change my scale, and not .flipX

hexed terrace
rich adder
hexed terrace
#

right, yeah

#

it'd come "towards" the screen as it rotates, if it's not an instant rotation

rich adder
#

yeah it would look all skewed lol

remote path
#

scale.x *-1

rich adder
#

its usually when I strictly want the 2D physics/light engine

#

otherwise i just use 3D objects with sprite renderer

#

navmesh is less of pain to deal with

remote path
#

unity gives free a* for 2d pathfinding. Not sure if they removed it

#

So you dont need navmesh

yea

ancient igloo

Just hadnt used before

And I have used Git

swift crag

you mean GitHub?

ancient igloo

Ye

whats the question again?

ancient igloo

And actual Git

#

I shared the clip

swift crag

presumably you're talking about making a Gist on GitHub

I suppose you could commit your work, push it to a website that hosts your git repo, and then send us a link

ooooor you could use a pastebin

# autumn tusk ok hold up

so im making a 2d topdown shooter and im wondering what method of doing this would be best

im rendering the player body and player hands as two seperate objects, both of which are rigidbody2ds.

the player hands arent gonna have collision, is it worth using a dynamic sprite instead?

swift crag
#

dies internally

wintry quarry
#

there's no reason for the hands to be a Rigidbody from that description

oh weird, I never noticed that

wintry quarry
# autumn tusk

Rigidbodies are for physics.
Sprites are for rendering.

These are two completely unrelated concerns.

gloomy timber
#

I cannot understand and solve this error.

wintry quarry
#

TerrainManager.TerrainGeneratedHandler terrainGeneratedEvent = TerrainManager.TerrainGenerated; this line of code is nonsense

#

you can't assign an event to a delegate variable

#

as the error is saying

#

what are you trying to do here

gloomy timber
#

I tried the invoke, I tried all the usual ways

wintry quarry
#

Do you know what event means?

gloomy timber
#

I'm starting a ritual

swift crag
#

throwing random stuff at the wall won't fix your problem

wintry quarry
#

It means the delegate can ONLY be invoked from the class that owns it

#

you are trying to invoke the event from a different class

#

it doesn't work that way

#

either:

  • get rid of the event keyword
  • make a public function on TerrainManager that invokes the event and call that instead of trying to invoke the delegate directly
swift crag
#

I often do something like this:

public event System.Action Florp;
public void DoFlorp() { Florp?.Invoke(); }

I'm posting in the beginner, don't blame me 😅

Hi,
I have a wierd error that I havent come across before.
I have set up a prefab and a runtimeIntilizeOnLoad on a static class so that all my necessery objects are loaded no matter what scene I use. This is all working as inteded.
However when I load a scene for a second time it seems like these cant find in the scene.
I have a simple funtion

GameObject.Find("playerParent").transform)

that is beeing called when

(SceneManager.GetActiveScene().isLoaded)

This works the first time the scene is loaded but not the second.
I have never had this problem before and therefore im thinking that the fact that I use the runtimeInilize somehow is to blame

guys I am starting game development right now
I followed a tutorial to make this movement script but when I try it on unity it has a visible input lag... is it normal?

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

public class PlayerController : MonoBehaviour
{
    public float moveSpeed;

    private bool isMoving;

    private Vector2 input;
    
    private void Update()
    {
        if (!isMoving)
        {
            input.x = Input.GetAxisRaw("Horizontal");
            input.y = Input.GetAxisRaw("Vertical");

            if (input != Vector2.zero)
            {
                var targetPos = transform.position;
                targetPos.x += input.x;
                targetPos.y += input.y;

                StartCoroutine(Move(targetPos));
            }
        }
    }

    IEnumerator Move(Vector3 targetPos)
    {
        isMoving = true;
        while ((targetPos - transform.position).sqrMagnitude > Mathf.Epsilon)
        {
            transform.position = Vector3.MoveTowards(transform.position, targetPos, moveSpeed * Time.deltaTime);
            yield return null;
        }
        transform.position = targetPos;

        isMoving = false;
    }
}```

Have you debugged your values here, and that currentHP is being set to new values?

Yeah, you dont set your other stats after adding your scriptableobject in your constructor

either read directly from the SO, or set the variables in your character class as the SO base values

Ah, text is the text COMPONENT property on OverheadDamage

Poor naming, which caused confusion

timber tide

yeah keep those variables, but set them from the SO in the constructor

pulsar lodge
timber tide
#

You're right, if you level up and have more vigor you want those variables

#

so, technically your calc methods will look like this:

    public int MaxHealth
    {
        get { return Mathf.FloorToInt(Base.HP + ((Base.vigor + vigor) * 5)); }
    }```

maybe name your non-base variables like extraVigor,

I was imagining it was going to try to divide a string by 2 :p

pulsar lodge
#

@timber tide Do you think it would be wise to make current values for each of my stats and then set them to = that stat, like i did with Health and Mana,

image.png
timber tide
#

depends how you want to do it

#

you can read once the SO and set values from it, or make your variables add extra values like I did above

buoyant knot
#

is that an SO?

timber tide
#

it cuts down on a step if you always read from the SO though when you deserialize everything

buoyant knot
#

it would need to be separated into a separate non-SO class

timber tide
#

it's a plain data class

pulsar lodge
#

Sorry im still pretty new, what is SO

timber tide
#

scriptable object

buoyant knot
#

scriptable object

pulsar lodge
#

ah

buoyant knot
#

is maxHP like a constant? or is it a system where it changes like in a JRPG

pulsar lodge
#

variable, not constant

#

exactly what you said

#

supposed to be a JRPG-like game.

buoyant knot
#

then i would do it like how you have, except make those properties have private set

sullen flare
#

help I dont know why my procedurally generated rooms are so small now

buoyant knot
#

you don’t want random classes being able to modify these externally willy-nikly

pulsar lodge
#

Well, i would want a class to be able to modify it when i get a level up i would think

#

but i could be thinking about this wrong

buoyant knot
#

yes.

#

with methods

#

not direct access

timber tide
#

property fields are kinda methods in a sense

buoyant knot
#

object oriented programming is inherently dangerous, so you want to really restrict access to changing things as much as possible

timber tide
#

just need to expand the logic out on them instead

swift crag
#

I also happen to be designing an RPG-y stats system right now

#

You need to draw a line between the data that changes and the data that doesn't

#

Suppose a Fighter has a base strength of 10, and also gains 2 strength per level up

buoyant knot
#

whenever you change currentHP, that would need to be coupled to checking death etc… There should be a public method for changing currentHP that handles any logic for changing chrrent HP

swift crag
#

Suppose you then update your game so that the Fighter has a base strength of 15 and gains 1 per level up

#

If you just stored the strength stat directly, your old save games would now be bogus

#

you'd have the wrong numbers

buoyant knot
#

in pokemon, you’d need to not just change HP, but change the color of an HP bar, start/stop playing near death music, change pokemon’s animation from being hurt etc

#

you don’t want external classes to just straight-ass modify currentHP

swift crag
#

not because an evil hacker will change the HP

pulsar lodge
#

so all of these should be private?

image.png
swift crag
buoyant knot
#

public int myInt {get; private set;}

swift crag
#

yeah, public getter + private setter is very useful

buoyant knot
#

thenever you allow public set, you better know wtf you are doing, because that shit can go south real fast

timber tide
# 
private float currentHealth;
public float CurrentHealth
{
    get { return currentHealth; }
    set
    {
        if (value > maxHealth)
        {
            currentHealth = maxHealth;
        }
        else
        {
            currentHealth = value;
        }
    }
}```
Like something like this instead of methods is fine too.
#

I do like just making methods though

buoyant knot
#

i would make it private, and make public void ChangeCurrentHP(

timber tide
#

either way, it's exposed one way or another

#

unless you bind some delegates if you wanted

buoyant knot
#

not totally exposed. we’re separating misc crap that needs to happen a bit more

#

and if you just call currentHP = 5; that doesn’t really convey that you have more going on under the hood

swift crag
buoyant knot
#

yeah

swift crag
#

You can still have methods that directly adjust your health

#

But you want to use the right tool for the right job.

buoyant knot
#

I would also make public event Action OnHealthChanged;

#

so other things can know if something just changed

rich adder
#

this, but I typically pass the amount too

timber tide
#

delegates probably the best way if you really don't want it to be touched

pulsar lodge
#

yeah i havent really gotten all the way to that part yet, just getting my initial values set right now

timber tide
#

and set through a constructor

rich adder
#

incase they need to know for some reason

pulsar lodge
#

and values that can influnces those initial values

rich adder
#

Action<int> OnHealthChanged
or w.e

buoyant knot
#

you need to really protect it

#

i can’t stress enough how much you want to restrict that value’s exposure

timber tide
#

I wouldn't worry too much until you're set on the logic and scope

swift crag
buoyant knot
#

i have made a generic of this if you want, I think

pulsar lodge
#

sure, i would love to see it to compare

timber tide
#

Like, if you've been using unity you're forced into a dependency injection pattern anyway, which already kinda screws with these methods

#

you don't always have the privilege of using a constructor, so that removes a lot of variables you'd otherwise set as readonly.

buoyant knot
#

this does allow the set to be fully public

#

in using it, you would: public ReactiveValue<bool> myBoolean { get; private set; } = new();

#

this fully exposes the Set for anyone, but also calls the event for anything listening to go off

#

in your case, you would want something similar to this, but it would be inside of the definition of the class where you are using it

#

example (with private set):

#

how do you deal with multiple controller inputs, and how do you link an input to a player actor?

buoyant knot
#

@pulsar lodge understand?

timber tide
swift crag
#

i wouldn't say that's "depednency injection"

#

or that it forces you to use it

#

but then again, DI is literally just passing arguments to something

buoyant knot
#

dependency injection is a shitty name tbh

timber tide
#

well, it sets you up for DI which is actually convienent because pooling gameobjects is ideal

pulsar lodge
# buoyant knot <@124330927659810817> understand?

i think i do lol. Sorry i am such a noob. I've dont have a ton of experience yet and Unity feels like a whole new world to me, can be a little overwhelming to take it all in at once. School has not prepared me for this haha, most of my stuff i've done has been 1-2 class projects.

I really appreciate all the help @buoyant knot @timber tide @swift crag

swift crag

because you give AddTwo the numbers instead of making it make it up its own numbers

rich adder
buoyant knot
swift crag
#

I've found it very hard to nail down any more meaningful of a definition

timber tide
eternal needle
buoyant knot
#

dependency injection is when you have A=>B, and then you change it to A=>C<=B

#

=> is depends on

rich adder
#

real DI when you do it in console apps xD

swift crag
buoyant knot
#

most dependency injection is using a base class or interface

rich adder
#

maui flashbacks

swift crag
#

the classic example of DI I always see is turning this:

public class Foo {
  public void Bar() {
    Logger logger = new ConsoleLogger();
    logger.Log("Hi");
  }
}

into this:

public class Foo {
  Logger logger;

  public void GiveLogger(Logger logger) {
    this.logger = logger;
  }

  public void Bar() {
    logger.Log("Hi");
  }
}
#

therefore DI means "give something an X instead of having it figure out its own X"

DI is when you give something values

buoyant knot
rich adder
eternal needle
# swift crag DI is when you give something values

In unity that's probably a fair description, although I'd still argue the int example isnt DI since the script is just being used as a calculator. It is not using the "injected" values at all, doesnt even store them

True DI is overkill for unity imo

OnTriggerStay is not the right thing to use here.
Use OnTriggerEnter/Exit, or a direct physics query, and keep a collection of the enemies so you know how many there are.

HashSet<Collider2D> enemies = new();

void OnTriggerEnter2D(Collider2D other) {
  if (other.CompareTag("Enemy")) {
    enemies.Add(other);
    Debug.Log($"New enemy count is {enemies.Count}");

    if (enemies.Count == 1) {
      Debug.Log("No longer empty!");
    }
  }
}

void OnTriggerExit2D(Collider2D other) {
    if (enemies.Remove(other)) {
      Debug.Log($"New enemy count is {enemies.Count}");

      if (enemies.Count == 0) {
        Debug.Log("Empty!");
      }
    }

I've just never really been convinced that DI is some specific pattern or design philosophy

#

maybe this is just a matter of semantics

#

and sometimes I look at the Zenject README and my brain explodes

#

(oh my GOD it's so long)

swift crag

#

Anyway, my example of bringing up DI was just to show that you can be stingy with access modifiers since inheriting from monos does not allow you to set otherwise private data in the constructor. You can of course set it through the inspector if it's serializable, but otherwise use plain data objects if we don't want these variables to be accessable.

when the spawner is done spawning enemies, it should tell the wall that it's done

then, when every enemy has been destroyed, the wall can disappear

no, the unary minus operator is a prefix

summer stump

Vector3.Reflect is often used for bounces

#

by default, the field will not contain anything

#

Or just use the built in physics and manually keep the velocity at a certain speed (magnitude)

If you move via transform then you need to do manual collision checks

I don't really understand what's going on here. Are you assigning meshProText when the OverHeadDamage component starts?

#

meshProColor will just be a color

#

and a color is a struct: it's just a value

#

if you do meshProColor = meshProText.color;, that just copies the current color into the variable

#

changing meshProColor will do nothing to the text color

#

if you need to change the text color, change the text color

Google is your friend, but for unity a good example would be making some utility classes which you can freely access without a direct reference.

ex.

{
    public static Vector3 CreateDirection(Vector3 startPoint, Vector3 endPoint)
    {
        Vector3 direction = endPoint- startPoint;
        direction.Normalize();

        return direction;
    }
}

public class Character : MonoBehaviour
{
  private void MoveCharacter(Vector3 startPoint, Vector3 endPoint)
  {
      //Calling this class directly by the name/type to access its methods because it's static
      Vector3 direction = VectorUtility.CreateDirection(startPoint, endPoint);
  }
}```

hey guys I have a quick, somewhat obscure question that I hope someone would be able to answer. I'm currently making a keybind manager script for my game, HOWEVER! writing a reference for each individual key was kinda annoying, so I decided to write a script that takes a string I write beforehand and add it to the list of "key references" (which is a struct I made just to reference keys see which one is being pressed etc), and I noticed that the keycodes appear in Visual Studio with an integer beside them, implying to me atleast that there exists somewhere in the editor, an array with ALL of the keycodes (image included where I noticed this)

it really is fine if nobody knows because what I have now works fine, but is there a way to access keycodes using an integer for the keys index in this array? it would help me a lot. thanks for your time if you dont know anyways guys

# autumn tusk i know you set the variable to public but what then

That is not really the only way. What referencing a value(variable) on another script really requires is getting a reference to the OBJECT (c# object, not necessarily unity GameObject) that HOLDS that value.
So, if you can, you can make a public field of the Type the other script is. Say it is MyScript
You would have
public MyScript script.
Not a public field for the value, but for the SCRIPT

Then you drag in the object with that script you want into the box in the inspector.
Then you can do
script.Value

You can't always just drag it in though, so I'd need to know more specifics.

Also see here for all the ways to set up references

# crisp token you can only peek() at the first element?

You can Dequeue() to get the first element off the queue. It's the design pattern of a queue, you can't, and shouldn't be knowing what's in the queue except for the first element.
It's like a real life queue at the supermarket for example. People arrive at the end of the queue, and people in front are processed first. First In, First Out (FIFO) collection type

but if it works then it's all good

If you need to look at any element, then use a simple List or array, queues are not made for such manipulations

chilly vigil
crisp token
#

it's continuously updated

short hazel
#

Yes sure, that's one of the use cases

crisp token
#

oh wait, i'm actually so dumb, it works perfectly for what I need

#

nvm

#

Thank u

short hazel
#

Dequeue one (or more) elements each frame if there are any in the queue

#

And process them

nimble blaze
#

is there anyway of making my character move just the x axis instead of turning the y axis into 0?

#

BeeRB.velocity = Vector2.right * speed * horizontal;
}

rich adder
nimble blaze
#

BeeRB.velocity = new Vector2(1 * speed * horizontal, BeeRB.velocity.y);

rich adder
#

BeeRB.velocity = new Vector2(horizontal * speed , BeeRB.velocity.y);

nimble blaze
#

like thatt=

#

oh i got it xd

#

i dont think i even need the 1 right

#

because horizontal gives a value of 1 through -1

#

thanks you

short hazel
#

Multiplying anything by 1 does not change its value, so yep it's not necessary to have it here

summer stump

You have a check for when all enemies are killed, so that should be about the only change you need. It will call when they die, then wait for the time, then spawn them

destroyed gameobject still exists for some time, right?
summer stump
swift crag
#

also note that the c# object will continue to exist

#

so even if the unity object was instantly destroyed, it wouldn't matter at all

#

the c# object isn't actually becoming null

#

that's just a trick that anything deriving from Unity.Object pulls

rich adder
#

yeah Unity overrides != and == for Unity.Object

viral hemlock
#

Can someone plz explain to me why I’m passing through objects even though I have colliders on each object

rich adder
#

also how do you move (code)

viral hemlock
#

public void MovementPlayer()
{
// this block of code gets the left, right, up, down movement
horizontal = Input.GetAxisRaw("Horizontal");
vertical = Input.GetAxisRaw("Vertical");

if (Input.GetKey(KeyCode.LeftShift))
{
    rb2D.velocity = new Vector2(horizontal * playerSprintSpeed, vertical * playerSprintSpeed);
 
}
else
{
    rb2D.velocity = new Vector2(horizontal * playerMoveSpeed, vertical * playerMoveSpeed);
    
}

}

#

my colliders are all circle 2d

#

exept for the capsule

#

nothing was changed on them

rich adder
#

lemme see gizmos

viral hemlock
#

pardon

rich adder
#

the green edges of the colliders, do they match

#

turn on gizmos

viral hemlock
#

ok

thats one client sure

And for example, if my game has a garden and a house, one person can edit the garden and the other the house at the same time, but until one of both people stop editing the house or the garden the oder must not edite the same thing, i'm right?

rich adder

#

but what if the house is over the garden on the playmode view?

#

how could i do that?

#

what's the proper pattern to pingpong a list?All_Ally[(int)Mathf.PingPong(TurnCount, All_Ally.Count - 1)];

#

nvm that's working already

#

something else was the problem

nimble blaze
#

hello everybody can somebody borrow me their super genious head

#

so i had this problem for a bit i kinda figured it out but now i added a new mechanic and now it kinda broke my mechanic

#

if(Input.GetKey(KeyCode.Space) && BeeRB.velocity.y <= 0)
{
BeeRB.gravityScale = 0.5f;
}
else
{
BeeRB.gravityScale = startGravity;
}
//Fall Faster
if(BeeRB.velocity.y <= 0)
{
BeeRB.gravityScale = fallGravity;
}
else
{
BeeRB.gravityScale = startGravity;
}

#

so i had these two one was for gliding and the other one was for falling faster

#

if 2 methods depends on one will just one execute?

polar acorn
eternal falconBOT
polar acorn
#

Code runs top to bottom, one line at a time.

#

Whichever one sets gravity scale last wins

nimble blaze
#

wait so you are telling me they cannot change the same value but it is in the update method

polar acorn
#

And whichever one changes it last is the one that "wins"

#

Because that's what the gravity scale is at the end of the function

nimble blaze
#

oh ok so what could be a solution for this?

late burrow
#

how would i do unzipping files

polar acorn
rich adder
nimble blaze
#

i can just put them together in the same if let me try that because they both use the first condition

#

i will try and see

#

omg its works @polar acorn thanks a lot

Hey guys. Im making this silly golf game, and was wondering if anyone knew how I can achieve the effect in the video of Camera parent and ball child rotation, without actually having the ball the child of the camera? I've tried applying the same rotation to the golf ball but it doesn't have the exact same effect.

#

for the camera I'm simply adding a y value to the eulerAngles

late burrow
#

i need to access Application.dataPath but access denied how do i give it path permissions

sterile radish
#

why would one use an enum when they could use an integer?

swift crag
#

which is more grokkable?

mode = 3;
mode = GameMode.Deathmatch;
#

You can also enumerate all valid values for an enum type

#

with System.Enum.GetValues

#

the compiler can also check that you've handled every valid enum value in a switch expression and warn you if you missed one

sterile radish
#

oh so they are more flexible and better understandable then right?

swift crag
# 
titleText.text = mode switch {
  GameMode.Deathmatch => "Deathmatch",
  GameMode.CTF => "Capture the Flag",
};
#

if I added GameMode.TeamDeathmatch to the enum, I'd get a compiler warning

swift crag
sterile radish
#

Okay, thank you so much! The examples made me understand a lot better to :)

swift crag
#

no prob (:

smoky niche
#

So RaycastHit2D.point can be used with raycasts, and I remember seeing you can also use Raycasthit2D.point[0]. Does that return the colldier you hit first?

#

Or is there no difference?

ivory bobcat
#

Point is a Vector 2 not an array of objects

#

Using the indexer operator ([]) well yield you the x or y component of the Vector 2

timber tide
#

How does this even work in 2D

ivory bobcat
ivory bobcat
timber tide
#

Ah, I guess if you have colliders overlapping it makes sense

swift crag
#

it's just like 3D

#

the raycast simply does not stop when it hits something

timber tide
#

Yeah, im just thinking how you don't really have depth, but stuff that overlaps would be the usage

slender nymph
#

you do know that you can use a direction other than Vector3.forward for a 2d raycast, right?

timber tide
#

Oh, true

smoky niche
#

Oh okay thanks!

#

So it returns the Vector2 where the ray hits the collider then

timber tide
#

For the RaycastAll? You'd get back an array of hits which you can then access to get a point in space for each.

#

People say it's not always ordered from which is hit first, but you can iterate over the array then order it yourself too.

smoky niche
#

No I meant for the normal Raycast

#

Oh that's good info thanks

timber tide
#

Point would give you the vector2

How do I write a script for movement in fps I wanna use it for a bird

nimble blaze
#

hello quick question my character move with velocity but in the end of my movement my character kinda drags a little bit
hatebin.com/fuqfvwpwdv

#

i can just put the velocity to zero after the movement but i want it to decreased not completely stop so i doesnt look so robotic

slender nymph
#

what do you mean by "drags a little bit"?

#

also you need to share more of the code than that

hidden path
#

I googled it and I am not able to understand the code given there, there is no explanation how it works

nimble blaze
#

like after the velocity it still retains some velocity after that so it start moving by itself slowly

slender nymph
#

you're probably using GetAxis instead of GetAxisRaw

nimble blaze
slender nymph
#

called it

nimble blaze
#

wait so i need to just changed getrawaxis?

summer stump
nimble blaze
#

what is the differenced?

summer stump
slender nymph
#

GetAxis includes input smoothing which means your input will reduce to 0 over time after releasing the key(s)

summer stump
#

GetAxisRaw is ONLY -1, 0, or 1

slender nymph
#

of course you are also not setting velocity to 0 when there's no input anyway so it will retain it's velocity until its physics has made it stop or you start using some other input because you only apply your input when it is not 0

nimble blaze
#

well now it moves way faster and cooler but it still slides after the input

#

that is the thing i want to not make it stop completely but slowly slowly

slender nymph
#

then go back to GetAxis and remove the check for whether the input is 0

hidden path
slender nymph
#

or add more drag to your rigidbody

ivory bobcat
nimble blaze
#

well yeah the thing im trying to do, is putting some force over time

#

to neglect the amount generated after he stops

#

oh wait a moment i can just divide them because the action is on update so is gonna do that constatly

slender nymph
#

i'm guessing you missed the suggestion of adding drag to your rigidbody

nimble blaze
#

add more drag

#

let me try that

#

would it be linear or angular?

slender nymph
#

linear

nimble blaze
#

oh welp that does work

#

but it affects my y axis as well

true pasture
#

the second if statement never returns true, could someone explain why, i've tried to use context.duration before and never got it to work.

asvvvv.JPG
#

also I just realized invoke isn't doing what I want there but regardless I can't get the duration check to work

#

(the rest of the function works)

fierce shuttle
true pasture
#

unity events

#

on player controller component

fierce shuttle
# true pasture on player controller component

Ah, I havnt used that component to handle input, though likely what may be happening is that your function is only being called once when the input changes (for example, the first frame the key changed from not being pressed to now being pressed down) - you can confirm this by adding a Debug.Log to the start of that function, I believe there is a setting in the action map for the bind to allow it to continue receiving input, or possibly on the input controller itself, otherwise another solution would be to poll the input yourself in Update

ok thanks

i have no idea how to make an strom circle that works because the 2017 tutorial one is broken and the 2d one i am following is from 4 years ago

inner marsh
# 
{
    public Transform turret;
    public Transform turretBarrel;
    public Transform target;

    // Update is called once per frame
    void Update()
    {
        turret.LookAt(target);
        turretBarrel.LookAt(target);
    }
}
``` im trying to aim gun turrets at a target, but with the actual turrets they need to only rotate along the y axis while the rest stay null, but with this skript they rotate along the x axis as well, how would i get it to only rotate along the y axis for the turret and the x axis for the turret barrels?

the barrel is a child

# summer stump Yeah, but trying to look at its own x and z would cause issue

    public Transform turretBarrel;
    public Transform target;

    // Update is called once per frame
    void Update()
    {
        turret.LookAt(new Vector3(turret.transform.position.x, target.transform.position.y, turret.transform.position.z));
        turretBarrel.LookAt(target};
}``` the turrets are now on their sides

# hidden path i dont understand what it returns

google will lead you to the docs, you dont need to do anything in unity.
you give the method a direction in local space and it gives you that vector3 as world space. Local space means the position relative to another object, world space means its true location in the unity scene

summer stump
# chilly vigil ok here it is https://youtu.be/JuqRnsUUcho?si=b7PKrMzzoVjtvDml but he update his...

Yeah, I tried to go to his repo, but it doesn't even show those scripts. There was a download for a ChangeCircle script and it's just... significantly different than yours.
You've added and changed so much I'm not sure how to get back from there. There are so many fundamental errors and issues that I don't understand the reasoning behind. I'm not sure how I or anyone else can really help with that.
As hard as this is to say, and certainly to hear, I feel like... starting over may be a good idea.

Someone else may be able to help 🤷‍♂️ but there is a lot to unmodify.

summer stump
# chilly vigil he inclues the updated c# in the decpriton of the one

Yeah, I got that one too. It's just... SO different from your code.
There are so many things that just cannot be done in C# in yours. Like:

void Start()
{
    void Start()
    { }

    void Update()
    { }
}  // Start and Update should not be in ANY method.

CloseTimes[closeTimeIndex] // this value is an int, not an array (or list)

if ((int)TimeElasped > CloseTimescloseTimeIndex //missing a parentheses, missing the square brackets, and again, is an int not an array

StormCircle((float)(XRadius * (ShrinkRadiusFator * 0.01)))[1]; // this is a type, not a method, right?

NextCircleTime(); // this method doesn't exist

TimeElasped[closeTimeIndex] // this is a float, not an array

CloseTimes.count // int, not array

return -1;
CloseTimes[++closeTimeIndex]; // innaccesible because it's after a return

It's just... like nearly everything is not right

Hi everyone, just new here but already working on Unity for a long time I'm studying DOTS and for some reason my camera is rendering weirdly.

The blurry ones are my gameobjects that have a DOTS authoring component and the cannon doesn't have any script attached to it and it looks normal. Here's a preview of what's happening.

Here's how they should look like in a different angle.

I'm using URP and Entities.Graphics, maybe they are conflicting

Hello, i was converting a movement script with the built-in character controller from this https://docs.unity3d.com/ScriptReference/CharacterController.Move.html , to a state machine from here https://www.youtube.com/watch?v=qsIiFsddGV4 . There are 2 things that i want to ask

  1. When it transitions to the jump state, it immediately go back to idle state, does anyone know where the problem is and how to fix it? i think there is a split second it is still grounded so it goes back to idle state but i don't know how to fix it without changing the abstract class
  2. There is a delay when i want to jump using the state machine version compared to the non-state machine version where it is all smooth, does anyone know what is happening?

the code is here https://gdl.space/desotukixa.m

thank you 🙏

Is there a trick for deactivating objects for the pool system? Currently when my 1st spawn iteration finishes from the pool list, it refuses to start from the beginning and re-iterate.

# 
    {
        if (pool.Count == 0)
        {
            Debug.Log("Pool is empty, creating a new object.");
            CreatePooledObject(); // Optionally increase the pool size
        }

        var obj = pool.Dequeue();
        ResetObjectState(obj);
        obj.SetActive(true);
        Debug.Log("Object taken from pool and activated: " + obj.name);
        return obj;
    }

    public void ReturnObjectToPool(GameObject obj)
    {
        ResetObjectState(obj);
        obj.SetActive(false);
        pool.Enqueue(obj);
        Debug.Log("Object returned to pool and deactivated: " + obj.name);
    }

    private void ResetObjectState(GameObject obj)
    {
        // Reset object state as needed
        obj.transform.position = Vector3.zero;
        obj.transform.rotation = Quaternion.identity;

        var rb = obj.GetComponent<Rigidbody>();
        if (rb != null)
        {
            rb.velocity = Vector3.zero;
            rb.angularVelocity = Vector3.zero;
        }

        // Reset any additional components or states here
        Debug.Log("Object state reset: " + obj.name);
    }```
