hatebin?

yes i know

no im trying to get it from the MeteorFireScript so it can take the "bullet" rb2d since its a different gameobject

[rocky canyon]

hatebin

[radiant frigate]

i havent used that

[rocky canyon]

ohh im mixing up people

[radiant frigate]

ohhh

[rocky canyon]

sorry sorry.. lookin at two different scripts 😄

[radiant frigate]

makes sense

npnp!

[rocky canyon]

u want the rigidbody from the same object as the MeteorExplosion..
well, right now ur trying to get the rigidbody from the object.. the script is attached to.. not the explosionScript object..
GetComponent is just referencing This gameobject...

for it to reference another object u need to prefix it:
thatOtherObject.GetComponent<Rigidbody2d>();

[radiant frigate]

i know but i want it from the same item as the script is in

[rocky canyon]

so. if the rigidbody is on the MeteorExplosionScript object..
you'd just access it via the variable u assigned just above it..

explosionScript = GetComponent....
explosionScript.GetComponent<Rigidbody2D>();```

[tulip plover]

what can i do to send my code?

[rocky canyon]

ohh

use one of those links like the other guy did..

#💻┃code-beginner message

send the MeteorFireMovementScript.. b/c thats the script the error belongs to 👍

[radiant frigate]

https://gdl.space/etilaminug.cpp

maybe im just trying something with the rotation that doesnt work or doesnt make sense

idk could be

my brain operates in weird ways

[rocky canyon]

soo, errors 101:

• the number at the end of the error indicates the line number the error is on
• if there are (2) numbers, the first number is the character number, and the 2nd is the line number

transform.rotation = Quaternion.Euler(0, 0, explosionScript.amountOfBullets * (explosionScript.fireAmount / 360));
``` Something on this line isn't assigned..

[tulip plover]

so can i do this?
https://hastebin.com/share/xocecewoxe.csharp

[rocky canyon]

soo unity spits out an error when it reaches it

explosionScript most likely.. isn't being assigned correctly..

[radiant frigate]

let me check

[rocky canyon]

in what way? what part are u asking about?

[radiant frigate]

they spawn as different gameobjects instead of children

thats the problem

[rocky canyon]

👍 good eye

[radiant frigate]

how do i change the instantiate to make them childrens?

[tulip plover]

the problem is that when i shoot, the bullet go to the bullet hole, but if i shoot to an obstacle or the floor and then i shoot to the sky, the bullet go to the last bullet hole

[tulip plover]

this is the other script
https://hastebin.com/share/deruruhali.csharp

[rocky canyon]

you can
use gamething.parent = parentYouWantToSet;

orr another way is to use the Instantiate overload that lets u set the parent as one of the parameters

https://docs.unity3d.com/ScriptReference/Object.Instantiate.html

[radiant frigate]

oh didnt know you could do this

[rocky canyon]

this one here for example..

u could pass in the parent at teh same time u instantiate..

[rocky canyon]

either or will work

[radiant frigate]

so i just need to add transform after the transform.rotation?

[rocky canyon]

you should use an else statement.. that way if the raycast doesn't hit anything (which is whats happening when u shoot into the sky)
it just doesn't spawn a bullet hole

b/c if theres no hit.. it can't replace the old position u assigned

[tulip plover]

how can i make that?

[final glade]

Hey there,

So basically I have Defence tower game like pvz, where you drag and drop characters in specific check points, I want to change the color of the object once it is in the same checkpoint where another object that contains the script “TissueObject” exists.
Here is my code the issue is I don’t know how think of the logic because i am dealing with three colliders, the collider of the tissue game object itself and the collider of any other tissue game object and the checkpoint

https://paste.ofcode.org/P7nrnbPZCY8vyWCByBsb9a

[rocky canyon]

            if (Physics.Raycast(ray, out RaycastHit hit, distance))
            {
                Debug.Log("Hit something with the raycast.");
                // Spawn the Bullet Hole
            }
            else
            {
                Debug.Log("Didn't hit anything with the raycast.");
                // Don't Spawn the Bullet Hole
            }
``` ❔❓❔

if you aren't comfortable with using if else statements.. u probably wanna slow down a bit and try to solidify ur beginner coding concepts

[final glade]

I also want the way to be efficient not like Foreach, because it traverses all the elements which affects performance in case I have numerous elements.

[rocky canyon]

if u want it to be a child of the gameobject spawning it.. yea, its pretty much that simple..

referenceToSpawnedThing = Instantiate();
referenceToSpawnedThing.parent = gameObject;

// or
referenceToSpawnedThing.parent = this.gameObject; // i like to use *this* to make things super readible

[radiant frigate]

yay

[tulip plover]

thx, i´ll try it

[rocky canyon]

a simple solution would be to use tags to tag each collider

[final glade]

I think that just be looping on all elements, I want a cleaner way

[rocky canyon]

if(other.CompareTag("Thing1"))
{
// do thing1 action
}```

switch statement and a forloop

[rocky canyon]

could check for components if each collider has a different script

TryGets aren't expensive

[tulip plover]

and where i need to put that script?

[rocky canyon]

idk bro

[ivory bobcat]

You're already calling GetComponent in Update so you ought not to worry at all about minor details like foreach

[blissful yew]

Any reason why JsonUtility.ToJson(levelCompletionInfo) always writes empty string?

[rocky canyon]

ur already raycasting somewhere for positioning ur bulletholes..

[rocky canyon]

wherever that raycast is.. ur apprently setting the position of that bullet hole..

sooo... whenever you raycast fails don't add a bullethole..

[tulip plover]

i have this error

[final glade]

How should I do that

The problem I am facing is that the collider of the tissue I am dragging has the possibility to collide with one of them basically there are at least 2colliders 1 for the check point and the other is for the tissue if I place the tissue there and then drag another tissue towards it I don’t know which one it would collide with

When I tried compare tag it didn’t even work

[rocky canyon]

I don't draw bullet holes, but my test raycast does something similar..
If the Raycast hits then the if statement runs.. and I set the hit variable..
if the Raycast misses then the else statement runs.. and I set the hit variable to null

[rocky canyon]

may have to add an additional check.. if ur currently dragging (the object is moving) don't check
if ur hovering or have stopped dragging then check

not sure of ur set-up or ur game's goals.

[final glade]

I already did that

https://paste.ofcode.org/P7nrnbPZCY8vyWCByBsb9a

[wintry quarry]

Generally sharing the error message would be appropriate

As well as reading it yourself

[tulip plover]

ok

[wintry quarry]

You're trying to use variables that don't exist

[tulip plover]

i change the hit to my variable hitInfo

[wintry quarry]

You can only use variables that have been defined

[high marsh]

okay i still cant figure out how to get my character to go behind the decoration when its y is higher, i followed the tutorial but its just not working

[rocky canyon]

u just copied and pasted..

the reason mine works.. is because i have all those variables set up already

[ivory bobcat]

Maybe have the backfield serialized? (backfield is private with public access to getter/visible-in-the-inspector)
Json: https://docs.unity3d.com/ScriptReference/JsonUtility.ToJson.html

Internally, this method uses the Unity serializer; therefore the object you pass in must be supported by the serializer: it must be a MonoBehaviour, ScriptableObject, or plain class/struct with the Serializable attribute applied. The types of fields that you want to be included must be supported by the serializer; unsupported fields will be ignored, as will private fields, static fields, and fields with the NonSerialized attribute applied.
Suggestion: [field: SerializeField]
(Have not tested)

[tulip plover]

how can i change that variables?

[rocky canyon]

ray is a Ray variable..
hit is a RaycastHit variable..
distance is a Float variable..

you have to create them..

[tulip plover]

ok

[blissful yew]

yup, that's it 👍

I only read the part about 'class with serializable attribute' and not the next line lmao

[high marsh]

i made it transparency sort by custom axis like the tutorial says but my main character is always on top anyway, they are on the same layer level

[rocky canyon]

float distance = 50f;
Ray ray;
RaycastHit hit;

ray = new Ray(cam.transform.position, cam.transform.forward);

if (Physics.Raycast(ray, out hit, distance))
{
    Debug.Log("Hit something with the raycast.");
}
else
{
    Debug.Log("Didn't hit anything with the raycast.");
}```
heres the full block w/ the context.. (but u still can't just copy and paste)
you need to know how this stuff is arranged in the code, for it to be any kind of benefit to you

[cunning narwhal]

Hi again, back again with a humbling experience with git and git lfs and an overzealous gitattributes file, I think.. and this source control setup is a little.. complex.. and I'm slowly losing any confidence with my attempts at using version control

So I am using git and have the unity gitignore which is good, according to all. Git LFS has option 1 of using the popular gitattributes https://gist.github.com/nemotoo/b8a1c3a0f1225bb9231979f389fd4f3f or option 2, a version of it from someone who sounds like they know better than most on some quirks with it https://github.com/FrankNine/RepoConfig/blob/master/.gitattributes so I chose option 2 out of desperation for something I didnt have to mess with just in case

I got it set up, pushed changes, life was good... very long story short is that I reverted some changes, files stuck around still, I created my Unity project with spaces in the name, git doesnt allow that. Deleted the project, pulled latest from git, so I now have a differnt folder name which may not matter? Anyways loaded it up in unity and it worked but some addons I was using had missing required files which had me reimporting the entre assets and just caused a huge mess. I ended up just scrapping it all and starting over.

What am I doing wrong here?

[rocky canyon]

Commit -> Push
Pull <- Commit -> Push

commiting and pushing are the only things u really need to know how to do

if ur not working in a team

[cunning narwhal]

Thanks, I'll just scrap the whole LFS thing and just try to push stuff that isnt media that the default gitignore doesnt catch and save it elsewhere

I had a feeling I was overthinking it and I guess I was. This stuff is quite complicated. I'm used to another source control so git is a little odd in how it treats all of the deltas for a file which is how LFS was made to sort of deal with that, but, messy

[rocky canyon]

Consider Fork

I've been using it for little over a year now..
I don't know a whole lot about Git but its been easy enough for me to just keep backups on Git

[cunning narwhal]

I'll consider it. Unfortunate that it costs money for something I would only use for this type of stuff

[rocky canyon]

Ya, I try to avoid pushing too many assets..
I had one project where I pushed an Audio Library.. and it got soo bad it finally corrupted and I had to go back and get a backup from my Local Harddrive

i kept the library locally.. and only pushed the audio I used from then on.. And i still work that way.

[rocky canyon]

The program I just clipped is Free

https://fork.dev/

basically an alternative of GitDesktop

[cunning narwhal]

It's showing $60 for me with an evaluation period?

[rocky canyon]

but while you learn VC I'd suggest keeping Local Backups on ur HD or GDrive or something, until u feel comfortable..

i know thats kinda missing the point of VC.. but its some piece of mind when your working on a project that has weeks, if not months, invested in it

[rocky canyon]

ohhh crap mb man.. i guess it's gone Paid since I downloaded it

[rocky canyon]

oh wait.. the evaluation is indefinitely free..

they just ask for donation from time to time i guess

[cunning narwhal]

Oh ok, thats not bad then. I'll give it a shot. But yeah anwyays back to my issue though I'll just use the unity gitignore, throw stuff on a repo and make some local backups every now and then and call it a day

Thanks for the help

[rocky canyon]

ya, sadly i can't help with LFS stuff.. I had to have a colleague of mine walk me through it last time I used it

and even then I really didn't even use it for much.. so I haven't used it since then.. and that was a year or more ago..
so far all of my projects work fine with regular Git..

google drive gives you 15 GB.. so thats a good place to store your audio / graphic libraries that would eat up alot of space

[tulip plover]

i use that, i think i know how it works, but when i shoot to the sky, the debug text "Didn't hit anything with the raycast." doesn´t appears

[final glade]

I even tried putting it as you said still does not work!

[sour ruin]

Hi, I'm doing some procedural animation stuff and I'd like to be able to test the parameter changes on animations without running the scene. Are there any methods like OnDrawGizmos that get called outside of scene execution where it would be appropriate to do this? (accidentally asked on the advanced channel, deleted that one and reposted here)

[flint python]

Why does it complain about getting null when .Add(test) but for the if statement test is not null. line 19 is just calling the function. Any clue? thanks.

[sour ruin]

maybe calling .Add on a null object. enemyGroups_Enemies could be null

[brave compass]

You can use [ExecuteAlways] on the script class to get Update also working in edit mode.

[sour ruin]

ok awesome thanks. Is there a way of toggling this from the inspector?

[flint python]

yes, thanks

[sour ruin]

btw instead of an if else statement you can Debug.Log(test == null);

[brave compass]

No, you'd have to check it yourself.

[SerializeField]
private bool updateInEditMode;

private void Update()
{
    if (!Application.isPlaying && !updateInEditMode) return;
}

[topaz arrow]

Universal methods to make your life easier!

Takes in a float value and an image or text and sets the alpha to the specified value

public static void SetImageAlpha(Image image, float alpha)
 {

     if (image != null && image.color.a != alpha)
     {
         float R = image.color.r;
         float G = image.color.g;
         float B = image.color.b;
         float a = alpha;
         image.color = new Color(R, G, B, a);
     }

 }

 public static void SetTextAlpha(TextMeshProUGUI text, float alpha)
 {

     if (text != null && text.color.a != alpha)
     {
         float R = text.color.r;
         float G = text.color.g;
         float B = text.color.b;
         float a = alpha;
         text.color = new Color(R, G, B, a);
     }

 }

Best used in a static class

[sour ruin]

legend, thank you!

[flint python]

is there an execution order of awake() for different game object scripts? or can I create an execution order?

[summer stump]

There is not

The only way you can define it would be to have your own method that you call from a single object in the specific order you want

The need to do so is a bit of a concern though.
What problem are you wanting this solution for?

[flint python]

i have 2 scripts, 1 assigns a value to a variable, name, in Awake, the other script in Awake gets the name variable. In this case, i can try to move the get part to start then, thanks for the info

[summer stump]

Yes, always do SELF-referencing only in awake. Do external referencing in start. Even that isn't enough sometimes, but it always is fine for objects that exist before runtime starts. It is only with instantiating that it isn't guaranteed

[wintry quarry]

https://docs.unity3d.com/Manual/class-MonoManager.html

But yesterday when possible best to avoid

[rocky canyon]

    private void OnTriggerStay2D(Collider2D other)
    {
        if (other.TryGetComponent(out Green_Script green))
        {
            Debug.Log("Green is nearby!!");
        }

        if (other.TryGetComponent(out Red_Script red))
        {
            Debug.Log("Red is nearby!!");
        }

        if (other.TryGetComponent(out Blue_Script blue))
        {
            Debug.Log("Blue is nearby!!");
        }
    }```
I was mentioning using `TryGetComponent` which is alot better than setting a variable using `GetComponent` and then checking for `null` afterwards..
not sure what about your script isn't working.. But my bet is the setup.. Might try revising it a bit to make it work better for the dragging mechanic..
I just put my code on my mouse cursor b/c I don't have a dragging system to test yet..

setup is just Empty Script sitting on the Collider

[brisk kindle]

Hi everyone, I'm trying to get an object to follow my mouse in a room (like first video). I use raycast to determine the object I want to move and move the object following to the position of the mouse on the screen. But when i hit play and drag the object, it doesn't move like in the first video, the object will move like in the second video. Anyone know how to make the object move like the first video? Thanks a lot!

My code:

using UnityEngine;

public class Trash : MonoBehaviour
{
    [SerializeField] private Camera mainCamera;

    private GameObject _selectedObject;
    
    private Vector3 _originPos;

    private bool _dragging;

    private void Update()
    {
        if (Input.GetMouseButtonDown(0))
        {
            if (!_selectedObject)
            {
                var hit = Cast();

                if (hit.collider)
                {
                    if (!hit.collider.CompareTag("trash")) return;

                    _selectedObject = hit.collider.gameObject;
                    _originPos = _selectedObject.transform.position;
                }
            }
        }

        if (_selectedObject)
        {
            var pos = new Vector3(Input.mousePosition.x, Input.mousePosition.y,
                mainCamera.WorldToScreenPoint(transform.position).z);
            var newPos = mainCamera.ScreenToWorldPoint(pos);
            _selectedObject.transform.position = newPos;
        }

        if (Input.GetMouseButtonUp(0))
        {
            if (_selectedObject)
            {
                _selectedObject.transform.position = _originPos;
                _selectedObject = null;
            }
        }
        
    }
    
    private RaycastHit Cast()
    {
        var ray = mainCamera.ScreenPointToRay(Input.mousePosition);

        Physics.Raycast(ray, out RaycastHit hit);
        
        return hit;
    }
}

[rocky canyon]

I kinda see what ur going for now.. but the tissues detecting the collider?
i was thinking it was backwards.. your object was detecting the tissue

[rocky canyon]

you need some way of telling the object its up against a wall and shouldnt move any farther

all u need is some bounds

can manually set them.. or could use a box collider or something...
then clamp the position so it doesn't move any farther

[rocky canyon]

  BoxCollider room;```
```cs
  Vector3 minBounds = room.bounds.min;
  Vector3 maxBounds = room.bounds.max;```
```cs
   position.x = Mathf.Clamp(position.x, minBounds.x, maxBounds.x);
   position.y = Mathf.Clamp(position.y, minBounds.y, maxBounds.y);
   position.z = Mathf.Clamp(position.z, minBounds.z, maxBounds.z);
``` something like this makes sense to me

unless the room is an odd shape.. and then i'd have to think a bit more about it

[brisk kindle]

I see, i will try it
Thanks a lot!!

[rocky canyon]

good luck 🍀

Whenever I am on the ground my velocity continues to rise up until i jump, which is the only time it resets

I feel dumb whenever I start trying to understand what I'm doing, does anyone have good tips for me to learn?

[slender nymph]

learn the basics using courses like the ones pinned in this channel, then just keep making stuff and learning new concepts as you need them. understanding comes with practice and experience

[rocky canyon]

you should keep ur downwards velocity a constant while grounded.. instead of adding on to it over and over..

thats fine to do while ur airbourne.. but when grounded.. it shouldn't be accumulating

gravitySim is just a vector that gets added to the input vector i pass into my Move() function

[craggy ingot]

So add on that void to the end of my code?

[rocky canyon]

they're Methods or Functions.. void is the return type (so those functions don't return a variable)
and right here is where u keep adding the gravity... soo in there you could adjust how ur gravity logic is working..

no.. u can't just add it on.. u have to adapt it to the script u already have..

for 1 you don't call a function called ApplyGravity(); anywhere.. and even if u did the gravitySim variable isn't declared or used for ur characters move() function

[craggy ingot]

oh okay thank you

[rocky canyon]

are you following a tutorial? they should cover how to fix that..

[craggy ingot]

i am however they do not cover it

[rocky canyon]

b/c its a big issue.. esp if u walk off the top of a ledge or something

b/c you'll get hurled into the ground if ur velocity keeps growing 😄

[craggy ingot]

yeah dont want that lmao

[rocky canyon]

    private void Move()
    {
        ApplyGravity();
        CalculateSpeed();

        finalVector =
            (groundVector * finalSpeed) +
            (airVector * playerSettings.airSpeed) +
            (Vector3.up * gravitySim);

        if (jump.magnitude > playerSettings.jumpMagn)
        {
            finalVector += jump;
        }

        characterController.Move(finalVector * Time.deltaTime);
        jump = Vector3.Lerp(jump, Vector3.zero, playerSettings.jumpSmoothing * Time.deltaTime);
    }```
for context here is my Movement function

[craggy ingot]

im still a little new to c#, what does the final vector do?

[rocky canyon]

the finalVector i pass into my CCs Move() function is created by adding abunch of different vectors.. and then my gravitySim

it does the same thing as ur moveDirection

[craggy ingot]

and then gravity sim is its own declared float/var?

[rocky canyon]

its made up of inputs just like urs

this funciton is called in Update.. runs every frame

it gets all my vectors.. like urs.. and then adds in the gravity variable.

the AddGravity(); is also called every frame..

so its constantly either setting the gravity to 1 steady value (when grounded)
or.. adding onto it (if not)

[craggy ingot]

so i make the addgravity void and then declare it in the update void?

[rocky canyon]

like ur jump function's else does..

methods

u don't call them voids

[craggy ingot]

ah mb

[rocky canyon]

void is its return type..

[craggy ingot]

ohh okay

[rocky canyon]

like ur IsGrounded() method's return type is bool

[brisk kindle]

it's not work at all :((

[rocky canyon]

it could be a function.. as well public void IsGrounded().

[craggy ingot]

yeah to see if is isgrounded, true or opposite

[rocky canyon]

but hta wouldn't give u back ur true or false..

everytime this if/else runs.. that method returns it a bool.

so its basically like having a true/false right there in the if condition

[craggy ingot]

is that a bad thing?

[rocky canyon]

but if its void it just does stuff.

doesn't give anything back

[rocky canyon]

nah not at all..
https://www.spawncampgames.com/paste/?serve=code_777

[craggy ingot]

i thought this was gonna be a lot more simple lol

[rocky canyon]

heres a look at my CC... for context

[craggy ingot]

ok

[rocky canyon]

have you looked over ur script so u know what it does?

[craggy ingot]

what does serializefield do?

[rocky canyon]

and how it works? or is just copy-pasta

[rocky canyon]

you know how theres public and private fields?

[craggy ingot]

and noo the tutorial was not the best at explaining wheat everything does

yeah

[rocky canyon]

public variables can be accessed from outside scripts..

which alot of the times u dont want..
so u make a private variable instead.. so it can only be accessed within the script its in

[craggy ingot]

oh okay gotcha

[rocky canyon]

[SerializedField] can take a private variable.. and show it in the inspector..

so u can keep a variable private.. but still be able to assign it with the slot.. or see if its there

[craggy ingot]

gotcha

[rocky canyon]

i have alot more visible than i should. for debugging..

like i can see my gravitysim

as its working

[craggy ingot]

oh and then i see how you did headers for organization i likethat

[rocky canyon]

ya, it gets complicated and i have to keep up with whats what

[craggy ingot]

true

[rocky canyon]

but line 154 is where my apply gravity function is..

[craggy ingot]

i see.. and then where would i define it in my script

[rocky canyon]

and then i just do that modification before i pass in the vector to my cc

!code well if u'd post ur code correctly, i'd be able to pinpoint it for you a little better

i think i did that right

[rocky canyon]

if u can see it, we can see it

[craggy ingot]

oh ok

[rocky canyon]

i just noticed you have 2 Move() functions

[craggy ingot]

I do?

[rocky canyon]

you do.. you have 1 where u pass in ur movement vectors

and then under the jump check u have another

interesting.

[rocky canyon]

i'd make it just 1cs Vector3 combinedMovement = moveDirection * speed + velocity; characterController.Move(combinedMovement * Time.deltaTime);

  if (IsGrounded())
  {
      if (velocity.y < 0)
      {
          velocity.y = -2f; // Small negative value to keep grounded
      }
      if (Input.GetButtonDown("Jump"))
      {
          velocity.y = jumpForce;
      }
  }
  else
  {
      velocity.y += gravity * Time.deltaTime;
  }``` and then i'd do something like this.. where *if* ur grounded u either set ur gravity to constant `=` or jump and set it to ur jumpforce.. oor your *not* grounded.. and then u can add ur increasing gravity `+=`

[craggy ingot]

well now whenever I hit the ground It lilke slows the fall down right before i hit it

like im falling noramlly and it works, but right before I hit the ground my fall slows down

[slender nymph]

whatever you are using to ground check is checking too far

[craggy ingot]

im using a raycast

[slender nymph]

then your raycast is too long

[craggy ingot]

okay let me try shorting it

thank you both for your help, it works perfectly now 😄

[elder raptor]

I added a background in my canvas. But I have an issue where the 2D Game Objects are behind the canvas. How do I bring them in front of the background? Or do I have to make the background in world space?

[storm pine]

First of all I think your message doesn't belong here, maybe you should ask in #💻┃unity-talk , this is a code channel.
But I have something similar as you can see on the image so I'm going to answer how I did it if you are looking for something similar. What I do is create a Render Texture and associate with the Target Texture of the Camera component. After that on your UI you can create a RawObject that can also be associated with the RenderTexture. Just imagine it like a stream, where the camera is recording on a TargetTexture and you can see that stream on a RawImage like a screen. After that is working you can do some improves like adding the aspect Ratio Fiter on your RawImage to ensure the camera image won't be stretched or compressed and you can preserve the original aspect ratio.
Maybe there is a better way to do that, but I'm kind of new and this is the only way I found.

[stoic briar]

For me what worked was creating different sorting layers. So my background image is on the first layer, meaning anything on layer 2 and more will be displayed in priority, and thus end up in front of the background

[worthy tundra]

i forgor the name of the thing where you want to have states instead of strings

[slender nymph]

do you perhaps mean an enum?

[worthy tundra]

yes!!

i forgor sorry

[languid spire]

show the declaration of playerWeaponHitFirst

btw this statement 'a static value thats in a function' makes no sense

[burnt vapor]

You can always change a static value. No instance needed. I assume you worded your question wrong.

[sleek notch]

Hi can someone help me why it isn't working?

[vocal ginkgo]

How do you make it so that text inputfields don't automatically activate when they're selected with a controller movement input?

[wintry quarry]

Did you attach it to the object?
Does the object have a collider?

If this is for UI you should be using IPointerDownHandler and IPointerEnterHandler

[sleek notch]

Oh

Okay

Thanks

[wintry quarry]

BTW Button has a built-in sprite transition mode thing

You don't need to write this code

[sleek notch]

Maybe I'm blind but I haven't seen field for sprite

[wintry quarry]

Change transition mode to sprite swap

ok so im running into an issue with colliders

basically im using an a* enemy movement system which means that the system works with two colliders; one 2d box collider thats used as an actual hitbox for player attacks and another 2d circle collider which is used only for navigation and making sure enemies don't get stuck on obstacles while pathfinding

this is what an average enemy with this a* pathing algorithm looks like

problem im running into is with how my system works for one of the player's abilities

basically the player has a "bite attack" that for every collider spawns a pickup, and it spawns 2 per enemy right now, when i only want it spawning one

actually might have figured something out

[raven ferry]

Okay i tried my best trying to solve this on my own but were not able to. im currently making my first project which is a 2d hidden objects game. ive been working on mouse nagivation on screen and were able to make both dragging and zooming with mouse wheel to work. but trying to add a camera boundry has prop been the hardest thing in this project.
The game doesnt have a player character but has a custom cursor which ive tried using as a tracking point for the boundry. but i cant seem to fix the issue that when i try to run the game and drag it changes Z from -10 to 0 so i lose view of the game scene. ps. i really had no experince with coding before this project, so this is all very new. i tried incorporating the working CameraMove code that allowed for dragging of the screen with a new code that were supposed to track a player character and lock its camera view, but tried altering it for my need.

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

public class CameraMove : MonoBehaviour
{
    [SerializeField]
    GameObject player;

    [SerializeField]
    float timeOffset;

    [SerializeField]
    Vector2 posOffset;


    [SerializeField]
    float leftLimit;

    float topLimit;

    private Vector3 Origin;
    private Vector3 Difference;
    private Vector3 ResetCamera;
      private Vector3 velocity;

    private bool drag = false;


    

    private void Start()
    {
        ResetCamera = Camera.main.transform.position;
    }


    private void LateUpdate()
    {


        void OnDrawGizmos()
    {
        //draw a box around our camera boundary
        Gizmos.color = Color.red;
        //top boundry line
        Gizmos.DrawLine(new Vector2(leftLimit, topLimit), new Vector2(rightLimit, topLimit));
        //right boundry line
        Gizmos.DrawLine(new Vector2(rightLimit, topLimit), new Vector2(rightLimit, bottomLimit));
        //bottom boundry line
        Gizmos.DrawLine(new Vector2(rightLimit, bottomLimit), new Vector2(leftLimit, bottomLimit));
        //left boundry line
        Gizmos.DrawLine(new Vector2(leftLimit, bottomLimit), new Vector2(leftLimit, topLimit));
    }

    Vector3 pos = transform.position;
    pos.z = -10;
     transform.position = pos;
        if (Input.GetMouseButton(0))
        {
            Difference = (Camera.main.ScreenToWorldPoint(Input.mousePosition)) - Camera.main.transform.position;
            if(drag == false)
            {
                drag = true;
                Origin = Camera.main.ScreenToWorldPoint(Input.mousePosition);
            }

        }
        else
        {
            drag = false;
        }

        if (drag)
        {
            Camera.main.transform.position = Origin - Difference * 0.5f;
            Camera.main.transform.position = Origin - Difference;
            Camera.main.transform.position = new Vector3();
            Mathf.Clamp(transform.position.y, leftLimit, rightLimit);
            Mathf.Clamp(transform.position.y, leftLimit, rightLimit);
        }
        

        if (Input.GetMouseButton(1))
            Camera.main.transform.position = ResetCamera;

    }
}

ok so this is my current code which uses colliders instead of gameobjects like i want

    {
    Collider2D[] hitColliders = Physics2D.OverlapCircleAll(transform.position, 5);
        foreach (Collider2D collider in hitColliders)
        {
            if (collider.CompareTag("enemydead")) 
            {
                // collider.transform
                PickupGeneration(collider.transform.position);
                GameObject hitObject = collider.gameObject;

                legitkills++;
                print(legitkills + "killscount");
                
                Destroy(collider.gameObject);
                //animator.SetTrigger("Eating");

            }
        }

    }```

[raven ferry]

i assume thats meant for me, i will try to reformat it, thanks

[autumn tusk]

i can use a distanceto function to look for enemies with the "enemydead" tag no problem

but is there a foreach function i can apply to all gameobjects in range?

an overlapcircle would not work since thats looking for colliders, and every enemy with a* pathing has 2

[cosmic dagger]

if you have the enemies in a list, you can loop to check their distance . . .

[autumn tusk]

i could stick that in the levelmanager

because the issue is some enemies have a* pathing, others dont

[cosmic dagger]

also, you can filter the what colliders are searched based on layers. this will only check for colliders on specific layers . . .

[autumn tusk]

can you manually set layers per collider

[cosmic dagger]

it's per GameObject. this will remove the enemy tag check . . .

if you place the collider GameObject on an enemy layer, then every collider in that array will be an enemy . . .

or what ever layer name you need . . .

[autumn tusk]

what i could do is parent the a* collider, and give it a tag to ignore the player completely

then in the foreach function add something to make it ignore all colliders with that tag

[cosmic dagger]

yes, you can use the layer matrix to allow layers to ignore layers . . .

[timber tide]

you can search by interfaces or some component too

or your own flag enum

[cosmic dagger]

you can use a component, interface, or enum for that as well, instead of relying on a tag . . .

[timber tide]

Unity tags suck because they aren't bitwise

[autumn tusk]

i gathered

ugh this is kind of a headache

ok what if i gave the colliders which need to be ignored a material, and if a collider has that material it gets skipped

basically a bootleg tag for that collider

that seems like extra work. just use any of the options noted above . . .

[autumn tusk]

ok so what type of component would i use

[radiant frigate]

https://gdl.space/uzijuyosis.cpp okay i seem to confuse how to rotate the children at the moment of instantiating it, or maybe im confusing how transform.up works, but im guessing its rotation because when i check it has rotation 0 https://gdl.space/akogaxejoz.cs

[cosmic dagger]

no, you would check for a component those enemies have (in common). it's just like a tag, but not error-prone . . .

[cosmic dagger]

your suspicion behaviour calls mover.Cancel which sets the velocity to zero (therefore, it stops motion). then it check for idle, setting to true and changes its animation to idle. it makes sense to me why it freezes . . .

[radiant frigate]

does someone know the way to rotate it?

[teal mason]

Motion should stop during suspicion for a few seconds and the NPC should idle in place and then walk back to it's last patrol point. MoveTo() seems to continuously get called when SuspicionBehavior() moves to PatrolBehavior(), which is setting the walk animation repeatedly.

[radiant frigate]

it says i cant convert vector3 to quaternion

[teal viper]

You can't

[green ether]

a vector3 is a position not a rotation

[teal viper]

A vector3 is a vector. It's not necesserarily a position

[radiant frigate]

i imagined that, but how could i change the rotation? i searched in the docs and found Euler.angles but that doesnt work either

[teal viper]

But it's not a quaternion for sure

[teal viper]

Well, what did you try?

[green ether]

yeah mb

[radiant frigate]

this shows no error but then it doesnt rotate it at all

[teal viper]

Did you try debugging the resulting value?

Also, it would only rotate at the scene start(or the object's Start), since it's in Start

[radiant frigate]

what should i debug? the rotation?

[radiant frigate]

wouldnt it rotate at the start of the instantiate command?

[teal viper]

The value that you try to assign to the rotation(the one you ty to create a quaternion from)

[teal viper]

Yes.

[radiant frigate]

thats what it should do

let me give you context of the other script

each time the loop happens it should go up by 1 fraction of a whole 360º that depends on the amount of bullets

so if there are 3 bullets

[buoyant knot]

that doesn’t change the transform as a function of i tho

[radiant frigate]

oh wait i think i messed up and the 360 should go at the start

[frosty hound]

Your OnDrawGizmos is inside of your LateUpdate function, you need to take it out.

[frigid sequoia]

Your question is barely understandable and your code doesn't show much since it is relying on a few other scripts we don't know nothing about; but it seems your issue is that you are just adjusting the text to be the variable "score" instead of making it a string with the word first (for example "public string score = "Score: " + score;)

[teal viper]

Debug it then

[raven ferry]

where should it be and why should it not be inside of late update? i assume late update is a update that accours after update but still gets checked continuously?

[radiant frigate]

basically it says that z is -1

[frosty hound]

It should be on outside as its own function in your class, not embedded inside another.

[radiant frigate]

and that shouldnt be happening so imma go try to debug more things

[buoyant knot]

amountOfBullets is in local scope.

[teal viper]

You're probably not debgging the right thing.

[radiant frigate]

local scope?

[frosty hound]

OnDrawGizmo will run itself every frame, you don't need to put it inside of an update function.

[radiant frigate]

im doing debug.log(transform.rotation);

[buoyant knot]

actually nvm it isn’t

[teal viper]

And what type is transform.rotation?

[buoyant knot]

sry i misread

[radiant frigate]

what do you mean by type?

[buoyant knot]

either way, the explosion script should call a method to pass information into the other script

[teal viper]

A Type. You know, every object has a type in object oriented language like C#.

[buoyant knot]

amountOfBullets should be a private variable

then you will know exactly what you are trying to pass in to the other script

[teal viper]

https://learn.microsoft.com/en-us/dotnet/csharp/fundamentals/types/

[raven ferry]

WOW! they show up now thanks! but doesnt seem to lock the camera inside the boundry, imma see if i can make it work

[buoyant knot]

GameObject obj = Instantiate(…);
BulletScript bullet = obj.GetComponent<BulletScript>();
bullet.AssignRotation(amountOfBullets…)(

this is how I would do it

[radiant frigate]

i thought it was a vector3 but from what ive heard it isnt

[teal viper]

Did you look it up in the API docs?

[buoyant knot]

does it make sense what I am going for?

with a separate method, you can trace more easily exactly what is getting assigned to debug it

and also make sure the timing is right

[buoyant knot]

also i think i figured out the problem

[radiant frigate]

there are x amount of bullets spawning each round, how does the engine know to change the rotation to the latest one instead of just changing the rotation of one of them over and over?

[swift crag]

because obj is the object you just instantiated

it can't possibly be any other bullet

if Instantiate returned a random object from your scene, it would not be very useful (:

[radiant frigate]

i read the start and by type i think you mean int bool float vector3 vector2 etc etc

[buoyant knot]

you use an IEnumerator, that goes through its loop all on yield return null. Those all get instantiated. Then later, Start is called after they are all instantiated, so they all work on the same value of explosionScript.amountOfBullets

[swift crag]

no, the Unity documentation for transform.rotation

[buoyant knot]

so the method you are using will never work without passing the information into the bullet script the way I described

[teal viper]

No. I'm talking about the type of what you were debugging.

[swift crag]

it tells you exactly what the property's type is!

[radiant frigate]

ohhh

[radiant frigate]

its a quaternion

[buoyant knot]

this is definitely the source of digitalmonkey’s bug

or rather, it is definitely something that will block it from working

[teal viper]

And that's how quaternions look. They have 4 members and the last one is usually equal to 1.
But then again, everything else being 0 means that it's not rotated.

[radiant frigate]

okay i understand i think

[radiant frigate]

and as loup said it probably is because it instantiates all of them and then each one tries to get the rotation which is 0 since its a complete cycle and therefore every bullet has 0 rotation?

[buoyant knot]

each one reads the value in the script after it finished the loop. so they all use the same number

[radiant frigate]

i might be explaining it in a weird way but i think i understand what the problem is

[teal viper]

You should start with debugging everything. If you have assumptions, debug to confirm them.

[radiant frigate]

okay

on my way

brb

[buoyant knot]

as to whether or not the Quaternion math gets you the rotations you want is a different matter that fen and dlich are getting at

they are focused on getting the correct rotation given the right input

[radiant frigate]

yeah if im using quaternions it surely isnt working

since the math is kinda weird

i wanted to use euler angles

[buoyant knot]

in general, you want to multiply quaternions

a quaternion represents a rotation operator

[radiant frigate]

rotation operator?

[buoyant knot]

a single quaternion represents taking something with “no rotation” (identity), and rotating it in some way

that is what a rotation operator does. it apllies rotation

[radiant frigate]

okay

[buoyant knot]

quaternion multiplication corresponds to composition of rotation operators (which do not commute!)

[radiant frigate]

commute?

[swift crag]

A * B = B * A

that is the commutative property

and it does not hold for quaternions!

[radiant frigate]

oh

[swift crag]

I forget if they're associative

(A * B) * C = A * (B * C)

[buoyant knot]

(quaternion for 90Deg x rotation) * (quaternion for 90 deg y rotation) = (quaternion for both)

[radiant frigate]

okay so basically the order of the factors dont alter the product

[swift crag]

no, they do

[buoyant knot]

they are associative

[swift crag]

because the operation is not commutative

if it was commutative, then the order wouldn't matter

[swift crag]

phew

[buoyant knot]

commutative means order does not matter.
quaternion multiplaction is not commutative

[radiant frigate]

yeah i mean that its basically that law but instead of correct its wrong

[buoyant knot]

90 deg x then 90 deg y is not the same as 90 deg y then 90 deg x

[radiant frigate]

okay

[buoyant knot]

in general, if you do quaternionA * quaternionB, it’s like you start with rotation of quaternionB, THEN you rotate by quaternionA

[radiant frigate]

cant i just use euler angles?

[buoyant knot]

again: order matters

[swift crag]

isn't it the other way around

[buoyant knot]

the reason we use quaternions is because euler angles are fucky

[swift crag]

transform.rotation *= Quaternion.AngleAxis(45, Vector3.up)

this always rotates you around the +Y axis

[radiant frigate]

shouldnt it be that you start at quaternionA and rotate quaternion b=

?*

[buoyant knot]

i thought it’s like matrices, so it should be the way I said

[radiant frigate]

because of gimbal lock?

[buoyant knot]

that is one reason

[swift crag]

https://docs.unity3d.com/ScriptReference/Quaternion-operator_multiply.html

Rotating by the product lhs * rhs is the same as applying the two rotations in sequence: lhs first and then rhs, relative to the reference frame resulting from lhs rotation.

[swift crag]

that's one problem, yeah

[buoyant knot]

all the math of how euler angles work make them not behave well when applying rotation operators using them alone

gimbal lock is one symptom of that

[radiant frigate]

but i just want to instantiate an object with a certain z rotation

[swift crag]

okay, so use Quaternion.AngleAxis to compute the desired rotation

[radiant frigate]

isnt that something basic that should give no problem with euler angles

[swift crag]

Quaternion.AngleAxis(45, Vector3.forward) gives you a 45-degree rotation around the +Z axis

[buoyant knot]

Quaternion.Euler(my desired rotation) * transform.rotation => new rotation

[radiant frigate]

because im getting my mind blown by weird math and i just want to do a 101 thing

[swift crag]

still backwards!

[buoyant knot]

is it tho lol

[swift crag]

yes

[brave compass]

I remember it as parent * child

[swift crag]

unless you intend to apply that rotation before your original world rotation

[buoyant knot]

oh, maybe all my angles are just backwards

and i didn’t notice because 2D

[swift crag]

I had to learn all of this whilst writing code that stored position and rotation offsets from a parent to a child

i did it wrong in every possible way lol

[buoyant knot]

i only learned about commutators and shit for rotation operators when I did physical chemistry via quantum mechanics. I didn’t learn any of that shit in normal physics classes

which is theoretically when you should learn it

[swift crag]

but first, we need to talk about group theory

🎵 🎶

[radiant frigate]

why do i want to rotate a thing in the z axis and im just hearing that you are telling me things that get explained in a quantum mechanics class

[buoyant knot]

yeah, it makes more sense with group theory

[swift crag]

you don't need to understand anything about quaternion math to use rotations

just like you don't need to understand linear algebra to use transform.TransformPoint

Just use the methods provided by Quaternion.

[timber tide]

only thing to know is euler is a poopy head and likes to give you the gimbals

[radiant frigate]

what is even linear algebra lmao

[buoyant knot]

because your transform is 4x4 matrix that applies to the whole object

[brave compass]

I'll give you ten points if you can remember where Quaternion.Inverse goes to calculate the rotation offset of a child to its parent. I always have to double check my old code.

[swift crag]

Quaternion.AngleAxis, Quaternion.LookRotation, Quaternion.FromToRotation, ...

[radiant frigate]

i heard that a bunch of times

but in 2d it shouldnt matter right?

[swift crag]

        for (int index = 0; index < spline.Count; ++index)
        {
            BezierKnot knot = knots[index];
            Transform parent = transforms[index];
            positionOffsets.Add(parent.InverseTransformPoint(splineTransform.TransformPoint(knot.Position)));

            Quaternion knotWorldRotation = splineTransform.rotation * knot.Rotation;
            Quaternion toParentRotation = Quaternion.Inverse(parent.transform.rotation) * knotWorldRotation;
            rotationOffsets.Add(toParentRotation);
        }

i think this is probably right

it works, at least

[timber tide]

2d is fine for euler

[buoyant knot]

it does because your transform is still a 4x4 matrix

and your transform.rotation is still a quaternion

[swift crag]

2D rotation is conceptually simple, yeah

[timber tide]

2 axis of rotation = not likely to run into gimbals

[swift crag]

assuming you only spin around the +Z axis

[brave compass]

copied code, you cheated 😠

[buoyant knot]

because unity implements it all as 3D

[radiant frigate]

then why am i hearing something about quantum mechanics lol

my brain is getting filled with things it can only dream to comprehend at the moment

[buoyant knot]

in 2D, rotation can be represented solely as one number: z axis angle.
but unity uses the same transform framework for everything. So your transform is a 4x4, and your rotation is a quaternion (instead of just 1 number for an angle)

[silent ember]

is there a working workaround to calling coroutines in a scriptableobject?

[timber tide]

coroutine manager

[swift crag]

because the underlying mathematics are more complicated

do you know what homogeneous coordinates are?

[radiant frigate]

no clue

[swift crag]

yet you are making a 3D video game!

[silent ember]

how?

[buoyant knot]

also the 4x4 transform matrix includes scale, position, and rotation

[swift crag]

you don't need to know the intricate meaning of a 4x4 transformation matrix

you just need to know how to use the tools Unity gives you

[buoyant knot]

yes, you just need to know the rules

[swift crag]

Quaternion.AngleAxis(45, Vector3.forward) produces a 45-degree rotation around the Z axis

[timber tide]

call scriptable object -> scriptable object calls static instance coroutine manager -> coroutine managers makes coroutine on itself

[swift crag]

Who cares how the underlying math works?

[radiant frigate]

im making a 2d game if you are talking to me

[swift crag]

it's still rendered in 3D (:

[radiant frigate]

ohhh

[swift crag]

you just have a different camera projection matrix

I wish Unity just called it a Rotation

[buoyant knot]

first rule of quaternions and 4x4 matrices: don’t crack that shit open to look at or modify the actual contents

[swift crag]

Quaternion (along with the exposed x/y/z/w values) makes it look frightening

[radiant frigate]

what is even W

[swift crag]

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

[silent ember]

is it perhaps similar to this?

[radiant frigate]

💀

[swift crag]

Check out those static methods.

[frail laurel]

so i should make string with the word first?

[swift crag]

Unity offers many ways to create and manipulate rotations.

[radiant frigate]

what is a static method ?

[buoyant knot]

you know how complex numbers live in a complex plane, which is 2D? quaternions are like 4D complex numbers. which is why you should NOT look inside them to try to understand

the best way to think of these things is as operators

[swift crag]

any method you don't need an actual object to use

[radiant frigate]

oh so basically i should not try to understand quaternions

[swift crag]

Quaternion.LookRotation isn't being run on a specific object

it's just..a method, by itself

[frigid sequoia]

Most likely, yes

[frail laurel]

in the score script?

[radiant frigate]

so anything that has transform isnt one right?

[buoyant knot]

you should understand how quaternions work on each other, but you don’t need to understand the inner workings of a quaternion

[swift crag]

anything that you call on transform is non-static, yes

[frigid sequoia]

How are you showing the score on the canvas?

[swift crag]

you are calling a method on your specific Transform object

[frail laurel]

text

[radiant frigate]

now i dont understand what my problem is and how to solve it

[swift crag]

remind me what you doing

[buoyant knot]

the only things you need to know about quaternions is:

1. multiply quaternion => rotate the rotations
2. they don’t commute
3. don’t open them. do not read the x/y/z/w

[radiant frigate]

i came here not knowing the answer and now i dont know the question lmao

[frigid sequoia]

Can you be more specific?

[radiant frigate]

i want to rotate the z axis of a "bullet" depending on what bullet it is

[silent ember]

@timber tide it gave me a nullreferenceexception on my scriptableobject on the line calling the static instance manager

[radiant frigate]

with this math equation: transform.rotation = Quaternion.Euler(0, 0, explosionScript.amountOfBullets * (360/explosionScript.fireAmount ));

[swift crag]

Do you want to make the bullet spin around its local Z axis

or the world Z axis?

[radiant frigate]

whats the difference?

[timber tide]

Sounds like you didn't create the instance on the scene

[celest shoal]

Hello I have here a basic typing effect for a string when it is being displayed with TMP_Text. I want it so that each letter that is type, it will start off with alpha 0 and slowly the alpha will increase to 255/#FF, how would I attempt this? Thank you

[swift crag]

The former will make it spin the same way, no matter which way the bullet is facing

[buoyant knot]

so you get the quaternion for the rotation you want to apply (Quaternion.Euler(….)), you get your current rotation quaternion (transform.rotation), you multiply them together, and assign that in

[radiant frigate]

isnt it the smae?

[swift crag]

let me make a little demonstration

[buoyant knot]

bam. rotation accomplished

[frail laurel]

it has text and on the text ui it says Score and other text ui high score i attached the score script to obstacle

[teal viper]

Did you debug your code already?

[radiant frigate]

how do i get all that?

[silent ember]

oh lol yeah

[radiant frigate]

i now dont even know what i wanted to debug

[silent ember]

Thanks a lot!

[radiant frigate]

im just getting bombarded with info way above my level i think

[swift crag]

I'm guessing you want the left image.

[buoyant knot]

Quaternion.Euler(…) gives you a quaternion based on whatever euler angles you give it.
transform.rotation is the quaternion for your thing, which you can use to both read and write.

[swift crag]

Ah, I understand what you are doing now. My 3D example is not helpful.

[radiant frigate]

i want it to rotate on the blue arrow

[teal viper]

Code is in most cases Input => Processing => Output. If your output is not what you expect, then you should check the input and that you're aplying the correct processing to it. Now, break down your code with that in mind and tell me what you need to debug.

[radiant frigate]

the rotation

but the rotation is completely wrong for what ive heard

[teal viper]

You didn't break down anything. What is your input and what is the processing?

[radiant frigate]

my input are numbers and the processing a math equation?

[teal viper]

Okay, then did you debug your numbers?

[radiant frigate]

nope

on my way to do that

[teal viper]

Should've done that like 30 min ago

[frigid sequoia]

And... you are replacing by script the text to the current score right?

[buoyant knot]

@swift crag i think the quaternion order is a unity implementation detail. For normal quaternions, it is the order I described (A*B = do B then A). But i guess Unity does it in reverse.

or the documentation is flipped

[frail laurel]

yes

[swift crag]

yes, that appears to be the case

(another reason unity should have just called the damn thing Rotation!)

[frail laurel]

when i don't start it shows this

[buoyant knot]

i just don’t know why the hell they would implement quaternion multiplaction backwards

[frigid sequoia]

Then why are you surprised when the text that you are specifically telling to replace is getting replaced?

[frail laurel]

but when i start it shows this

[buoyant knot]

but idk, i do all my quaternion multiplication the correct way, so maybe it’s the unity documentation that is backwards

[frail laurel]

but how do i make the text don't replace only the numbers of the score and highscore

[frigid sequoia]

Obviously, you are replacing the default text you wrote for those values

[radiant frigate]

all 6 are the same

so the problem is even b4 the numbers

[swift crag]

because it makes way more sense for combining rotations

[radiant frigate]

so its in the for loop inside the coroutine

[buoyant knot]

not really, because rotation operators combine like matrices

[frigid sequoia]

As I said just make it a string and add "Score: " and "High score: " first

[buoyant knot]

it just makes it read chronologically instead of mathematically

[frail laurel]

any ideas how to fix it? i don't understand

[plush oxide]

in the IEnumerator thing, what does yield mean and return mean? the tutorials just mention their existence

[swift crag]

you are telling the text component to display a string

if you string does not start with "Score: ", then you will not see the word "Score"

[wintry quarry]

If you're talking about Coroutines in Unity, It means "pause the code here until <something>" depending on what you yield return

[buoyant knot]

ienumerators do a MoveNext every time you yield. Yield return makes the IEnumerator current value change to that value

[buoyant knot]

foreach (x in IEnumerator y)
basically does:
while (y.MoveNext)
x = y.Current;

[wintry quarry]

Maybe the text doesn't have room, or maybe other code is overwriting it

Or maybe you didn't save your code

[plush oxide]

interesting

[plush oxide]

im going to read that 5 more times

[buoyant knot]

so if you do:
Ienumerator MyEnumerator() {
yield return 5;
yield return 3;
Debug.Log(“hi”);
yield break;

then the IEnumerator gives you a 5, then a 3, prints hi, then a break

[swift crag]

If a method returns IEnumerator and has a yield instruction, the compiler turns it into a class with fields that keep track of the data in the method's local variables.

So there's no magic at runtime (:

[radiant frigate]

the problem is in the middle of both because inside the for loop the debug log is correct but when getting it from the other script its wrong

[buoyant knot]

yield break makes MoveNext false, which means you’re done

[swift crag]

share the entire script. !code

[radiant frigate]

just as loup said b4 it is becuase it take the information once the for loop is completed and therefore they all take the same number

[plush oxide]

so it waits 5 frames, then 3 frames and then says hi

[buoyant knot]

no

it returns the number 5

then returns the number 3

then prints hi (i changed the code)

then it breaks (done)

[teal viper]

Then pass the information to whatever needs it when you still have it.

[plush oxide]

i see

[swift crag]

when you start a coroutine, you're just throwing your enumerator into a list of enumerators. Unity calls MoveNext on each one each frame by default

[radiant frigate]

https://gdl.space/uzijuyosis.cpp https://gdl.space/akogaxejoz.cs

[buoyant knot]

unity coroutines use IEnumerators, and interpret the things you yield return to know how/when to wait

[radiant frigate]

i dont know how to do that im afraid, or atleast i cant think of how right now

[plush oxide]

hmm I see what you mean

[swift crag]

I see where the problem lies here.

So MeteorFireMovementScript has a Start method.

[teal viper]

Do you not know about methods with parameters?

[buoyant knot]

so if your IEnumerator does yield return new WaitForSeconds(5);
and it is a coroutine, then unity will do that, get WaitForSeconds object, it looks in that object and decides to wait for 5 seconds before going on in that IEnumerator

[swift crag]

In that method, you check explosionScript.amountOfBullets.

[radiant frigate]

i dont know what you mean by parameters right now

[buoyant knot]

you can use Ienumerators that are not coroutines

[swift crag]

Start runs the frame after you create something.

By this point, amountOfBullets is 6. Everyone sees 6 and does the same thing.

[teal viper]

Then it's a good time to go over C# basics. You're not gonna get far without understanding it.

[buoyant knot]

but if you start coroutine and give an ienumerator, unity will try to interpret the outputs to try to figure out waiting times or timing etc

[swift crag]

Yes. You really need to know some fundamental concepts here.

[buoyant knot]

you can also just make an Ienumerator to give a bunch of numbers, or strings, or whatever

@plush oxide make sense?

[radiant frigate]

my problem is im really bad at words, and i tend to forget the name even if i understand it

[plush oxide]

oh im reading

ill take like 2 mins and read

[buoyant knot]

ienumerators are used outside of coroutines, and you should know both. IEnumerators are really fucking useful

[teal viper]

Well, you can speak English to a degree, that means that you have the capacity to remember words. That's more than enough to learn the C# basics.

[plush oxide]

i see

im just trying to understand what you meant by It returns 5 then 3

[radiant frigate]

alright

[plush oxide]

what does returning 5 and 3 actually do

[radiant frigate]

what is considered the basics?

[swift crag]

yield return 5; makes the enumerator stop running and sets its Current property to 5

enumerator.MoveNext();
Debug.Log(enumerator.Current); // logs "5"
enumerator.MoveNext();
Debug.Log(enumerator.Current); // logs "3"

You can yield return whatever you want in a method that returns IEnumerator.

IEnumerator<T> requires you to yield return a specific type. It is the generic equivalent to IEnumerator.

[raven ferry]

im trying to create a object that will always be in the center of the screen that i can track, so like not at (0.0) but at the center of the screen no matter where i move inside a scene, what would that be called? having a hard time finding it by searching up on google/youtube. im having trouble with the boundries in my game tracking the cursor, so i thought maybe having a center object thats connected to the screen that the camera can lock onto thats then moved by the cursor drag might be worth trying

[swift crag]

some relevant terms here would be "screen space" or "viewport space"

https://docs.unity3d.com/ScriptReference/Camera.ViewportToWorldPoint.html

[raven ferry]

thank you so much, i will look that up

[plush oxide]

okay, I guess I got some of that but could you say it in REALLY easy terms

[swift crag]

what part do you not understand

i can't help you if you just say "i don't get it"

[plush oxide]

sets its Current property to 5

idk what enumerator current means

[swift crag]

https://learn.microsoft.com/en-us/dotnet/api/system.collections.ienumerator.current?view=net-8.0

An enumerator's job is to give you a sequence of values

[teal viper]

Well, for starters, understanding types, classes, structs, references, methods, parameters, class members, fields, different scopes, if statements, loops, instances(objects).

[swift crag]

Current is the ... current value

[plush oxide]

do you have an example perhaps

[swift crag]

It is part of the IEnumerator interface. Every IEnumerator can tell you the current value

[swift crag]

yes, this code is an example

[swift crag]

based off of Loup's code

[plush oxide]

okay

i guess ill read for 5 mins

[burnt vapor]

When you implement an IEnumerable and ask for the inner enumerator, Current is one of the properties that exist inside of it. It determines the current value to return, which in the case of a Coroutine would be WaitForSeconds for example, assuming you yielded with this class.

[swift crag]

List<int> integers = new() { 1, 2, 3 };
var enumerator = integers.GetEnumerator();
enumerator.MoveNext();
Debug.Log(enumerator.Current); // logs 1
enumerator.MoveNext();
Debug.Log(enumerator.Current); // logs 2
enumerator.MoveNext();
Debug.Log(enumerator.Current); // logs 3

[burnt vapor]

The other important part is MoveNext, which moves to the next value or returns false if there are none left.

[plush oxide]

ill just stop asking questions and wasting your time, because each time someone answers it has another word or something I dont know, so Ill just get to this later i guess

[swift crag]

you need to actually tell us which parts you do not know about so that we can tell you about them

"I don't get it" x100 is not useful

[plush oxide]

see

if I told you what I dont get

[radiant frigate]

okay ty!

[plush oxide]

we would be here for a while

[radiant frigate]

i will check into that

[swift crag]

ok

bet

[plush oxide]

fair enough

in the SIMPLEST terms possible, in real life terms perhaps, what is an enumerator

how bout we start there

so I can build on it

[swift crag]

let me make a thread

[plush oxide]

oka

[mystic heart]

I'm trying to make this little app (preferably in unity) where I have two phones, one phone is closed and the other has basic UI with just one button. Whenever I press that button, a notification should appear on the other phone, but i have zero clue 😆

Would I require a server of any kind that uses cloud code to push it?

I'm currently looking at the mobile notification package from Unity, it has like 80% of what I need

[raven ferry]

ive been trying to trouble shoot this for a bit but no luck. im trying to fix a issue with my game where the game finally respects the boundries i set in so the camera doesnt go past it, but now it keeps jittering between (x,y) and (-x, -y). Any suggestions for the cause?

[timber tide]

best to post code so people can help with the issue besides trying to guess

[raven ferry]

will do, its just because ive already posted it recently and wanted to avoid spamming

here is the script that causes jittering

[frosty hound]

You can share your code, but if you're trying to do bounds, you can achieve that with cinemachine and the confiner:
https://docs.unity3d.com/Packages/com.unity.cinemachine@2.3/manual/CinemachineConfiner.html

[timber tide]

also bounds class if not using cinemachine

[raven ferry]

i tried using cinemachine but for some reason i couldnt make it work, so i kept looking and found a tutorial on youtube that seemed to be applicable for my code. i could try and use it again because if i can make it work it would prop be way easier. ive used like two days on thisssss lmaoooo

[frosty hound]

I'm confused why you need lateupdate here at all, if you're moving your camera in Update and already clamping it to the left/right limit? Also your clamping of the transform is using the y value for both x and y.

[raven ferry]

ive been following guides and tried to understand how the code works, im still not too sure on the difference between late update and update but this is how atlest 1 portion of the code in this script was set up. this is like my first experince with real coding and game making so im trying to learn as much as i can lol.
so if i understand correctly i should remove late update and put its contents under update? oh shit yeah thanks i completly overlooked that! thanks!!

[icy junco]

just a quick question when adding aiming is it best to use an animation for aiming or just like moving the object with code?

[queen adder]

If you're trying to do something like, have your character aim where you mouse is, you would use Inverse Kinematics for your arms and maybe head.
If you're referring to having just a standard aim, you could just animate it.

[frosty hound]

It's hard to say specifically what you should do because there's lots of ways to do the same thing. But it just stood out to me that you're already clamping in update, so I'm not sure what the purpose of late update here is.

Personally, I'd just use cinemachine for this (and what I've done myself)

[icy junco]

thanks aiming isnt realy like such a big thing in my game so i will just use animation thanks

[queen adder]

np

[queen adder]

Update vs. Late Update
You could imagine it like a drive through to order food, 1 car is 1 frame. Late Update happens at the last window where you pick up your food. Also, I'm very hungry, and was thinking about what to eat 😅

[hushed hinge]

well, it's doing good so far

and right now it have tutorial boards

i also made a parkour part where you have to run over the holes since you can't jump over them because of the platforms above

[frail laurel]

anyone could help?

[rich adder]

thats what happens when you use AI to write

it doesn't work and you cannot fix it

[stoic glen]

Where can I find those settings? I can't find it inside Player settings

[rich adder]

not a code question. did you try the search bar in the Player Settings?

[stoic glen]

Yes, ther is nothing highligthet

[rich adder]

need a bit more context on the problem you're trying to solve here

[stoic glen]

I can't get a sound. But it is shown in the master that something is playing

On Mobile

[rich adder]

where did you find this "fix" though

also are you trying to test on mobile how ?

[polar acorn]

Why would it? You don't have anything anywhere that adds 5 seconds to the timer. Maybe show where you're trying to do that and we can try to see why it doesn't

[keen needle]

Is there a way to change the name of element 0, element 1....?

[rich adder]

iirc if the first field is a string it does show

[zenith cypress]

^ or a custom editor/property drawer

[wintry quarry]

public string name on the elements

[keen needle]

is not working

[swift crag]

on the elements

oh, I see

I misread the name of the list

[swift crag]

so FuncionesProcesos is the type of the list displayed here?

[wintry quarry]

Did you actually set any of their names?

[keen needle]

I think no

[wintry quarry]

then that's why

it will take on whatever name you give

also pretty sure it should be called name not Name but not sure if that makes a difference

[silent ember]

Hello. I know that this should cause unity to crash because it's an infinite loop but it doesn't.

Instead, it continues counting and the game runs normal.

I'm confused on why this is the case.

[cosmic quail]

yeah thats how coroutines and yield return null works

[wintry quarry]

It doesn't because you are doing yield return null; which means "Pause here, come back to me next frame".
During that pause, the rest of the game engine is able to do its thing

whereas a loop without that would not allow the rest of the game engine to run between iterations

[silent ember]

ohh

So what if I want to freeze the game while the conditions aren't met?

Let's say until SkillQueueNumber is more than or equal to 10 perhaps

[languid spire]

remove the yield

and add a yield break at the end

[wintry quarry]

That's silly because you could then replace all of this code with:

int SkillQueueNumber = 10;```

Although actually your code as written in this screenshot will simply never enter the loop

[silent ember]

like this?

[wintry quarry]

0 is not more than 10

so the loop will simply be skipped

[silent ember]

oh silly me

[wintry quarry]

also there's no reason for this to be a coroutine now

since it isn't doing any yielding

[silent ember]

This is just a simple example I'd like to be explained

[wintry quarry]

well in this code you make a variable, set it to zero.
Then the while loop checks if 0 > 10, and it's not, so it skips the loop
Then the function ends

this all happens immediately

[silent ember]

because before I thought that if you put "true" on the while condition, it would be an infinite loop and crash the game

[wintry quarry]

Yes if you do that without a yield inside, that will happen

[languid spire]

if you did that now, it will

but, as Praetor says, without a yield actually breaking processing there is no need for it to be a Coroutine

[west sonnet]

I have an object that I want to animate just once. What's the easiest way to do that?

[silent ember]

This was the original code and I was wondering why it prematurely stops without fulfilling any of the conditions

[wintry quarry]

set up your state machine to transition to the Exit node after the animation

[wintry quarry]

which conditions is it not fulfilling?

[silent ember]

But anyways, thank you all for the help

[sage spruce]

@west sonnet uncheck the looping and it will play only once

[wintry quarry]

If you want to, you can always attach the debugger and step through the code

and see what's going on

[silent ember]

The queue.length one

[west sonnet]

But I want to start it via a script

[wintry quarry]

wdym by "it's not fulfilling" the condition? Add some Debug.Logs to see what's going on

[silent ember]

but yeah, yield shouldnt be there

[languid spire]

that code is so bad for many reasons

[west sonnet]

For some reason in Unity, you can't just do Animation.Play()?

[wintry quarry]

if you don't want a yield there, there's no reason for this to be a coroutine

[wintry quarry]

You can, if you're using an Animation component

(the legacy one)

[sage spruce]

@west sonnet set it not to loop and then enable animator component from script

[zenith cypress]

Can also use it with the animator to force play an animation state in your animator controller

[wintry quarry]

You also can yes call Animator.Play https://docs.unity3d.com/ScriptReference/Animator.Play.html

[silent ember]

It's supposed to go through all the elements in the array then stop whichever element is not null

[silent ember]

I'm sorry 😔

[wintry quarry]

but yeah this code is scuffed

for one, it seems to think arrays are 1-indexed instead of 0-indexed?

for two, there's no handling for the case when there are no skills available in any slot

In that case, the loop will go on infinitely

[languid spire]

think what happens if all entries are null

[silent ember]

thanks for pointing that out

I didnt think of that

I guess it should check whether at least one of the slots has a skill?

is that right?

[meager sentinel]

Which way can i make a bullet which i can change the speed even after it's been spawned?

[wintry quarry]

I guess I just don't really understand why you would use a while loop here

a for loop would do just fine

and be less risky

[west sonnet]

I can only using animation.play() if I change the animation to legacy?

[languid spire]

yes

[meager sentinel]

because i see most people use things like adding force to rigidbodys, but i want to be able to add or remove force while it's in movement

[wintry quarry]

you can do it with either

but you will need to provide the parameter with either one

[wintry quarry]

By... writing code that does it.

[wintry quarry]

What makes you think force can't be added while it's moving?

[empty ice]

Hi guys, quick question.
Im trying to make a very simple main menu with Ui button, when the button is clicked music fades out and scene is switched. However the scene does switch after some time but for some reason the music doesnt fade out. Why could that be?

public AudioSource MenuMusic;

public void StartShift() 
{
    StartCoroutine(PlayGamee());
}


public IEnumerator PlayGamee() 
{
    MenuMusic.volume = 90;
    yield return new WaitForSeconds(0.5f);
    MenuMusic.volume = 80;
    yield return new WaitForSeconds(0.5f);
    MenuMusic.volume = 70;
    yield return new WaitForSeconds(0.5f);
    MenuMusic.volume = 60;
    yield return new WaitForSeconds(0.5f);
    MenuMusic.volume = 50;
    yield return new WaitForSeconds(0.5f);
    MenuMusic.volume = 40;
    yield return new WaitForSeconds(0.5f);
    MenuMusic.volume = 30;
    yield return new WaitForSeconds(0.5f);
    MenuMusic.volume = 20;
    yield return new WaitForSeconds(0.5f);
    MenuMusic.volume = 10;
    yield return new WaitForSeconds(0.5f);
    MenuMusic.volume = 0;
    SceneManager.LoadSceneAsync(1);
}

[wintry quarry]

Read the docs for volume

https://docs.unity3d.com/ScriptReference/AudioSource-volume.html

Values of 90 etc don't make any sense

[silent ember]

I just want it to stop when it finds something that isnt null

[empty ice]

Oh. That explains it, I feel like an idiot now. I've been trying to fix this for like an hour now and nothing helped.

[languid spire]

Also, make it a loop please

[meager sentinel]

Yeah but i mean i dont know how to make it like RBforce (obviously a example) = 500f and not Rbforce * 500f

[wintry quarry]

Yes you can do that, in a for loop

[silent ember]

and I think that using a while loop would be the easiest

[empty ice]

So to my understand im supposed to do
1 then 0.9f and so on?

[wintry quarry]

It sounds to me like you're confusing forces with velocity

[meager sentinel]

kinda

[rocky canyon]

rigidbody.velocity =

[languid spire]

yes

[rocky canyon]

would directly set the rigidbodies velocity

[wintry quarry]

Velocity is a property, you can set it directly to whatever you want https://docs.unity3d.com/ScriptReference/Rigidbody-velocity.html

[silent ember]

how can i make it stop? I'm thinking putting it inside an if statement or something

[empty ice]

Alright, thanks!

[rocky canyon]

while volume > 0

[wintry quarry]

sure but this manually writing of all of them is kinda silly, you should just use a loop and change it every frame not every half second

[rocky canyon]

then when its not.. loop ends

[wintry quarry]

Like I said, a for loop

you literally just write a basic for loop that goes over the array once

[empty ice]

Im trying to learn IEnumerators since i've never used them before so thats why i wrote it like that at first. Later on im gonna try to add some Float fade out duration, so that it calculates automaticly

[silent ember]

but how do I get the next available skill?

[wintry quarry]

Isn't that the whole point of the loop?

[meager sentinel]

yeah but that makes me not be able to add velocity like forward

[wintry quarry]

Why do you think that?

Of course you can

you can do whatever you'd like

[meager sentinel]

Because it says X Y Z, not like the addforce

[wintry quarry]

what?

[meager sentinel]

Like in addforce you can add forward

[summer stump]

Addforce takes a vector as well

[wintry quarry]

Ok and with velocity you can set a velocity that is "forward"

[summer stump]

Wait, are you writing rb.velocity.x =
?

[meager sentinel]

Oh thank you, i will test

[wintry quarry]

For the record, there is literally nothing you can do with AddForce that can't be done by setting velocity and vice versa. They are two differently shaped handles that ultimately do the same thing

The only end-result of calling AddForce is that the velocity of the body changes

[silent ember]

Sorry I'm kinda stumped. I'll just use a for loop to check if the whole array is empty and a while loop to get the next available skill.

[wintry quarry]

You only need one loop

You are overcomplicating it

write a single for loop that iterates over the array and finds the first available skill it sees.

[meager sentinel]

My Visual Studio seems to be bugged or something now

yesterday it worked just fine with unity but now it doesn't detects errors

[summer stump]

Regenerate project files in the external tools menu

[silent ember]

But what if I want to start at the second element and the only other element in the array is in the first?

[wintry quarry]

that's a simple manipulation of the indices in the loop

[meager sentinel]

But what would be forward? Sorry for overask since i dont understand too much about rigidbodys

because in AddForce you can do transform.forward

but you cant in velocity

[wintry quarry]

e.g. cs int startingIndex = whatever; for (int i = 0; i < myArray.Length; i++) { int effectiveIndex = (i + startingIndex) % myArray.Length; var element = myArray[effectiveIndex]; }

[languid spire]

yes you can

[wintry quarry]

transform.forward or rb.rotation * Vector3.forward

[wintry quarry]

what makes you think that?

you are making stuff up!

[meager sentinel]

When i tried it said transform.forward dint exist

[wintry quarry]

you did something wrong, unrelated to AddForce and velocity

show your code

and your error

transform.forward exists so long as the code you're writing is in a MonoBehaviour derived class

if not, that has nothing to do with AddForce and velocity, it's a whole separate issue.

[wintry quarry]

why are you writing new Vector3(transform.forward, 0, 0)??

[wintry quarry]

that is not the error you said it was

it's an error because your code is nonsense

[languid spire]

transform.forward is a Vector3 you are using it wrong

[wintry quarry]

rb.velocity = transform.forward

remember it's new Vector3(x, y, z) not new Vector3(anEntireVector3, y, z)

[meager sentinel]

Well i mean that was what i saw from the unity doc

[wintry quarry]

no it is not

You copied it incorrectly

show where the unity docs have that

[silent ember]

wow it's been a while and I still can't fully understand this, I don't think I'll be writing code of this level anytime soon.

Thanks!

[polar acorn]

Notice how that doc doesn't have a whole ass vector inside a vector

[wintry quarry]

Ok and do you see new Vector3(transform.forward, 0, 0) there? No.

[wintry quarry]

I think what you're missing here is that velocity accepts ANY Vector3. Doesn't matter where it comes from. So you have many options there. You can:

• Create a new one with new Vector3
• Use one from another place or something such as transform.forward

But new Vector3(transform.forward, 0, 0) itself just does not make any sense, because transform.forward is not a number you can plug into x in the x, y, z of a Vector3, it's a whole vector itself.

[meager sentinel]

Well i dint know that

[swift crag]

instead of parking your car in the garage, you're trying to park the car in itself

[wintry quarry]

Let's say you have a garage with 3 spaces for cars. Instead of putting 3 cars in your garage, you're trying to put another whole 3 car garage in one of the 3 spaces 😭

[west sonnet]

Am I doing something wrong here? My animation isn't playing

[polar acorn]

Do you have an animation state named "Base Layer.+1 Pizza"

[wintry quarry]

Anything in the console?

[west sonnet]

This, right?

[west sonnet]

No

[polar acorn]

That is an animation in the base layer named "+1 Pizza". There's nothing named "Base Layer.+1 Pizza"

Consider checking the documentation for .Play to see how layers are used:
https://docs.unity3d.com/ScriptReference/Animator.Play.html

[swift crag]

The example code does suggest you can do that...

although it also provides an explicit layer ID

[wintry quarry]

Is the code even running?

[swift crag]

note that you're already in that animator state

[west sonnet]

Wouldn't it play when the game is started then? Which it isn't

[west sonnet]

In the example, it's writted "Base Layer.Bounce"

Hence why I also put Base Layer

[swift crag]

i would start by making sure that:

• the animator is doing anything at all
• your code is even running

[polar acorn]

Yeah I just noticed that. That's... odd. They still provide the layer as a number, which is how you'd play an animation in a specific layer, I don't know why they also put the layer name on it? But I think the issue is in what Fen's saying.

[swift crag]

I have seen that syntax before, where you specify both the layer name and the state name

I don't use the Animator much so I don't know too much there

[west sonnet]

My code is running. Everything else in the same method works just fine. I don't see any activity in the animator tho, not sure why

Do I need to create a seperate empty state so that I can transition from the empty state into the animation?

[swift crag]

You would want that, yes

[west sonnet]

What am I doing wrong now? If I press B, nothing happens

The trigger isn't enabled in the animator

[wintry quarry]

Is your code running?

[west sonnet]

Yeah, I've confirmed with Debug.Log

[wintry quarry]

Where did you put the log

[west sonnet]

Just below the anim.SetTrigger, so the Debug.Log happened when I pressed B

[wintry quarry]

Then either:

• You will see an error in the console about the trigger not existing (or some other error)
• the trigger is being set

[west sonnet]

But I'm not getting either of those, nothing is happeniing

[wintry quarry]

The bottom one is happening if you aren't getting an error

show screenshots of things

maybe:

• Your state machine is not set up to do anything with the trigger
• Your state machine is reverting to another state quickly
• You have error logs disabled in your console
• You're looking at the wrong animator

These are all possiblities

[west sonnet]

PizzaGained trigger is enabled in screenshot because I manually enabled it with mouse click

but it's not normally enabled

[wintry quarry]

which object do you have selected?

Are you selecting the animator that's actually in the scene?

[brazen mortar]

shufflee is a List<T>. Am I correct in thinking that this code will set shufflee to be a shallow copy of what it previously referred to? Or is there a better way to do it?

[slender nymph]

you are correct. it's a new List object containing the same elements

[brazen mortar]

thanks

[shadow briar]

Does anyone have any links to any references i can use for not using Update() / fixed update() for movement and the sort.
So using WASD to move around, and each input calling its selected movement method, so W for Forward as an example.

Cause far as i know from Unreal constantly using Update is somewhat a no no, but not sure if Unity is different in that regard.
I've been searching around for any videos, scripting manuals that could help me and so far just been a brick wall, as each thing i've found just makes use of Update.

[slender nymph]

there's nothing wrong with using Update when you need to, and for the most part you will need to use Update for movement, just maybe not polling each key individually. if you use the input manager look into using the GetAxis methods. if you use the input system you can use events to react to changes in input which will clean up your Update and FixedUpdate methods significantly

[rich adder]

new input system is based on events so you can use that, but there is nothing wrong with polling for inputs in update though

[shadow briar]

Alright, cheers for the information, many thanks.
I'll give this input system a look and take it in forward that its not wrong to use Update.

Cheers again

[pallid sandal]

rigidbody.AddForce(Vector3.up * 500);
doesnt work to make player jump

i tried everything (with code and rigidbody in inspector)

[slender nymph]

you're likely overwriting velocity somewhere

[pallid sandal]

i have another script for movement

maybe that

[slender nymph]

probably

[pallid sandal]

it worked, thanks

[tiny dagger]

does anyone know how to turn this off?

the low resolution aspect ratios

[languid spire]

might not be a bad idea to not subtract and add to the timer in the same method

[rotund forum]

Hello.

I am having a terrible time of trying to make my play rotation function work in a way that looks good. The attached video, in the later half, shows a jitter when I am holding a directional input, moving the player, and rotating the camera at the same time.

The following is the function, HandleRotation(), that I call in fixed update. My inputs are assigned in update. The player's rigidbody is not kinematic and has interpolation on.

If anyone can help me I would greatly appreciate it. The function does work I suppose. But it looks quite ugly when I'm rotating the camera while moving the character.

{
    Vector3 _targetDirection = Vector3.zero;

    _targetDirection = _cameraTransform.forward * _playerInputManager._verticalInput;
    _targetDirection = _targetDirection + _cameraTransform.right * _playerInputManager._horizontalInput;
    _targetDirection.Normalize();
    _targetDirection.y = 0;

    if (_targetDirection == Vector3.zero)
        _targetDirection = transform.forward;

    Quaternion _targetRotation = Quaternion.LookRotation(_targetDirection);
    Quaternion _playerRotation = Quaternion.Slerp(transform.rotation, _targetRotation, _rotationSpeed * Time.deltaTime);

    transform.rotation = _playerRotation;

}```

if you are using rigidbody you should not be using transform, use the rigidbody equivalents

private void UpdateTimer()
{
    timer -= decrementSpeed * Time.deltaTime; // decrement timer each time the method is called

    if (timer > 0) // if the timer is still greater than 0
    {
        // log the time and set the color
        timerText.text = $"Time: {timer:F1} seconds"; // string interpolation to add time variable inside string
        timerText.color = timer <= 10 ? Color.red : Color.white; // ternary operator to set color w/o bulky if/else
    }
    else
    {
        // timer is 0 or less
        Debug.Log("Time's up!");
        Respawn();
        timerText.enabled = false;
    }
}```
here's how i would do it 🆓 🐝 
i just wanted to refactor some code to get my brain working today 😄

Why is this recommended? I applied the rotation to the rigidbody and I am having the same issue.

[languid spire]

because when you apply values to the rigidbody the transform is told about it, vice versa is not the case

[rotund forum]

I see. I'll keep this in mind. Thank you.

It's probably due to using slerp with the 3rd paramter just being a small value. Maybe you want RotateTowards, which your 3rd parameter would make sense for

[buoyant knot]

transform and rigidbody both modify the transform of the object

rigidbody does so via physics engine. transform does not.

so if you change transform, then rigidbody API will fight you over it

[languid spire]

also doing Slerp(current, final, t) rather than Slerp(start,final, %)

[buoyant knot]

in general, if you have a rigidbody, you should try to only move your object via the rigidbody commands

if you do not, then the transform is the only thing to mess with

[eternal needle]

This is what we mean by the lerp also

[buoyant knot]

if your rigidbody is kinematic mode, then I would try MoveRotation.

if it is dynamic, then you’re basically applying a bunch of torque/forces to try to rotate it, and it will be more difficult to get a specific rotation

[knotty ferry]

anyone know any script ideas how to make when obstacle respawns it would add 20 seconds to the timer?

[rich adder]

its pretty tame stuff

[eternal needle]

Which part do you struggle with?

[rich adder]

start small, build up

[buoyant knot]

make a system to control timer. make a system to respawn obstacle. then make them communicate

[knotty ferry]

addvalue i don't understand how to make to add value 20 to the text timer ui

[willow scroll]

Have a numerable variable, which updates the text

value += 20;

text.SetText(value.ToString());

[buoyant knot]

addvalue is a custom function you wrote

we’re not going to know wtf it does

[eternal needle]

Your timer isnt UI. It's a number, a float most likely. Your UI should be updating based on this float, not trying to update the UI directly

[rich adder]

"add value 20 to the text"
you probably want to add it to a variable and display that instead

[rocky canyon]

Respawn();

{
    // respawn logic

    // add time to timer
    timer += 20f;
}

timer still counting down..
and the else statement will run once more after getting below 0

public class UniqueID : MonoBehaviour
{
    [SerializeField]
    private string uniqueID;

    public string ID => uniqueID;

    private void Awake()
    {
        if (string.IsNullOrEmpty(uniqueID))
        {
            uniqueID = System.Guid.NewGuid().ToString();
        }
    }

    private void OnValidate()
    {
        if (string.IsNullOrEmpty(uniqueID))
        {
            uniqueID = System.Guid.NewGuid().ToString();
        }
    }

    private void Reset()
    {
        uniqueID = System.Guid.NewGuid().ToString();
    }
}``` Hi how can i get this to work on prefabs duplicates please

[eternal needle]

It is working, but just not doing what you want because the string is only being checked for null or empty.
You need some other way of checking what IDs already exist like a dictionary. Trying to do this automatically will be more of a pain imo than just having some button you can press to assign it a new ID.

[knotty ferry]

the script might be working but the text doesn't even update when obstacle respawns

[rich adder]

well which method/condition do you have to update UI ?

[knotty ferry]

i use Updatetimer to update ui

[rich adder]

and when do you call Updatetimer ?

[knotty ferry]

i think this might be issue InvokeRepeating("UpdateTimer", 0f, 1f); // update timer every second

[knotty ferry]

i call it at start

[rich adder]

and you certain this is running when you do += 20 ?

[knotty ferry]

i can add debug

to check

[rich adder]

[honest haven]

thank you
