[summer forum]

it was for a gamemanager script that restarted the game

so he didnt refrence it normally

with the refrence object

[grand snow]

i dont need a new description im good

[summer forum]

well you said its hard to understand

so i had to explain

[grand snow]

it was 😆
Anyway you seem to know that using a serialized field ref is better

If you load an additive scene and need to find one or a few objects from there its an acceptable solution to Find()
Else we usually avoid it.

[slender nymph]

if this "gamemanager script that restarted the game" is a persistent object (like being a DontDestroyOnLoad object) then it would need to find the player object each time it restarted the scene because the old player object would have been destroyed so it makes sense to use one of the Find methods there (though there are still better ways to handle it)

[summer forum]

well then wouldnt also other refrences that playerobject has be lost?

[slender nymph]

the new player object would have the new references. of course you haven't shared the tutorial or actual code, so this information could be entirely irrelevant

[grand snow]

my guy didnt use .CompareTag() CANCELLED

[summer forum]

just did it with refrence object and it worked just fine

[grand snow]

Hmm i wouldnt do what he did but it makes it easier for a beginner tutorial

no one past the beginner stage really does this so I think its all on purpose

[polar acorn]

Reminder:

[grand snow]

tbh I dont really know his skill but he does godot now

[polar acorn]

He's decent at the engine but he's not a programmer

he's a visual artist which is why the videos usually have good production values. Programming has never really been his strong suit

[grand snow]

Shame visual scripting was not around 8y ago as it is now.

{
    Vector2 moveValue = value.Get<Vector2>();
    Vector3 newPosition = new Vector3(transform.position.x + moveValue.x, 0, transform.position.y + moveValue.y);
    rb.Move(newPosition, transform.rotation);    
}```
Hello I'm learning the Player Input component, I tried this code to make my player move, but it always goes back to its initial position, is Move the wrong method, or am I doing vector manipulation wrong ? thank you 🙏

[shut swallow]

Don’t you have to multiply by time.deltaTime?

[sweet iris]

I don't know 😦

[shut swallow]

“When Rigidbody interpolation is enabled, Rigidbody.MovePosition creates a smooth transition between frames. Unity moves a Rigidbody in each FixedUpdate call” - scripting API

I mean if you have a velocity (your move vector) you’ll still need time for distance

[eternal needle]

am I doing vector manipulation wrong
add debugs and find out. do you know that this code is even running, how often is it running? these are things debugging will tell you

[sweet iris]

I was thinking of adding a speed variable so that it moves more smoothly but what I don't understand is why it goes back to its position before it moved

[sweet iris]

I am I just didn't include it in the sample

Debug.Log("newZ = " + transform.position.y + " + " + moveValue.y + " = " + (transform.position.y + moveValue.y));
Debug.Log(newPosition.ToString());```

[shut swallow]

Debugging will help you out

[sweet iris]

I still don't get it

[eternal needle]

part of your issue might also be that you're trying to move a rb outside of fixedupdate

input is handled every frame and not tied to the physics loop

[sweet iris]

that surprised me as well but I don't know how to do it outside the onMove callback

[shut swallow]

I’m not familiar with rbs because I like controlling behaviour more with kinematic stuff, I only heard of putting all physics in FixedUpdate, but didn’t know that input need to sync’d to FixedUpdate too

[eternal needle]

store the result of the input in a vector3. in fixed update, move the rigidbody by this vector. See if that fixes things

[sweet iris]

thank you

[eternal needle]

it's not syncing input to fixed update, input is handled by unity before the Game Logic part https://docs.unity3d.com/6000.1/Documentation/Manual/execution-order.html (the tiny Input Events part).
there are physics things you shouldnt do in update though so you need to store the input to use it in fixed update

unless there is something else wrong in the setup that i'm not seeing, I don't think much else could be going wrong here

[sweet iris]

I made the change but I get the same behavior, also since my moveVector is initialized a 0, 0, 0, the player is teleported at those coordinates, maybe Move is the wrong method ?

[eternal needle]

ive rarely seen people use .Move truthfully. though if you were going to use it, you would still add to the current position. I usually move rbs through the linearVelocity which you can try as a sanity test to see if it moves

[supple flume]

yall i need help with this

using System.Collections.Generic;
using System.Linq;
using Unity.VisualScripting;
using UnityEngine;

public class Systematic : MonoBehaviour
{
    public GameObject[] mauz;
    public int indicator=0;
    public ag agagag;
    public PetMover pet;
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        agagag = mauz[indicator].GetComponent<ag>();
        if (Input.GetKeyDown("space"))
        {
            pet.movepoint = agagag.LocalMove;
        }
        
        if (Input.GetKeyDown("right"))
        {

            if (indicator < 3)
            {
                indicator += 1;
            }
        }
        else if (Input.GetKeyDown("left"))
        {
            if (indicator > 0)
            {
                indicator -= 1;
            }

        }
        if (indicator == agagag.tilevalue)
            {
                agagag.hoverindicator = 1;
            }
            else
            {
                agagag.hoverindicator = 0;
            }
        
        
    }
}

so at first i tested this in a linear way, but now that i want it to read two ints as in indicatorx and indicatory, how can i register the same object with tiles while not being able to access the list

[ivory bobcat]

I'm not understanding your question. Can you rephrase it?

[supple flume]

as you can see in the script, the object selected is determined by the array's value, which is a linear number from left to right, but now i want to determine it by the selective location via an X and Y value, ill provide a vid

[ivory bobcat]

Use a 2d array? (or jagged array etc)

[supple flume]

dont mind the jump, its just a wrong assigned order

but i want it to do this with Y access too

[supple flume]

its the one wtih [,]?

it only shows numbers when i do it

wait i am mistaken, it just disappears

[rich adder]

Multidimensional arrays are not serialized in inspector

[supple flume]

i tried even serializing them

[supple flume]

so i can just add them by tags?

[rich adder]

you can't you'd need struct

[supple flume]

what is that

[ivory bobcat]

I'm not entirely sure what you're trying to do but if you've got a 2d grid of objects and are wanting to map it, a 2d array should suffice. Where you'd access elements using two values (x, y etc).

[rich adder]

Idk what ur doing lol I just replied to the thing not showing in the inspector

[supple flume]

no as in, how to assign them, i use tags?

[rich adder]

Assign what exactly?

[supple flume]

the 2d array values

[rich adder]

Like any other value =

[supple flume]

I want them to be given in order, that seems tff

Ooo i figured it out

erm help with this

[rich adder]

Mauz is null

[supple flume]

but i assigned them as 0,0

oh

[rich adder]

Did you not initialize it

Create the object mauz

[rich adder]

That doesn't answer the question lol

[supple flume]

wdym create?

[rich adder]

mauz[,] = new()

[supple flume]

oh

[rich adder]

assigning values to an array not created will def give you null ref

[supple flume]

i never knew i had to do that

[eternal needle]

you should most definitely do some c# basics first, there are resources pinned in the channel

[supple flume]

for normal arrays

i used them and didnt create it

[rich adder]

This isn't specific to arrays but any reference type

[supple flume]

oh

[rich adder]

Exception unity Objects but those are special

also normally unity creates object for you if you serialize it in the inspector like a regular poco/object (arrays is a good example)

[eternal needle]

🤷‍♂️ up to you, but you also seemingly have never seen a null error before. you can struggle through the c# part all you want while trying to learn unity too. it wont be fun

[supple flume]

all roads lead to rome

[rich adder]

You can't travel the road if you don't know how to walk

[eternal needle]

or as we've seen lots of times, beginners who give up because their code "stops working" and isn't possible to fix without rewriting everything. 6 months of duct taping and awful coding habits isnt sustainable. willpower wont create your game

[supple flume]

I am taking computer science in college, so in no planet ill lose intrest

[rich adder]

computer science isn't always synonymous with specific language coding

Plenty of compsci graduates who never coded a thing to save their life lol

[ivory bobcat]

For clarity, a null reference exception error occurs when you attempt to access a member (get component function in your case) from something that is null and not the thing we're trying to actually get (what we're trying to get can be null and it would be fine). So if a had a field named b and b had a field named c and c had a function named D..
If an nre had occurred when trying to:
access b, we can assume that a was nullcs var t = a.b;//nre if a was nullsame applies for the remainder:cs t = a.b.c;//nre if a or b were null t = a.b.c.D();//nre if a, b or c were nullIf we were to only access a, it would not throw an error during assignment as a being null is valid (you just might get errors later if you ever attempt to access a member of t):cs t = a;//no error even if a is null t.b = z;//nre: t was null but we're attempting to access the member b

[supple flume]

ik what null is, i just didnt read the error 🔥

[sour fulcrum]

My brain is being dumb this morning. I've got a list of world positions that i want to make a bounds out of. I know i can get the average position for the center but how do i calculate size?

oh can i just make a empty bounds and encapsulate them all?

[nocturne parcel]

Bounds out of?

[charred spoke]

If you know the centre then it would be faster to find the furthest point and then encapsulate just it.

[wintry quarry]

Just keep calling https://docs.unity3d.com/2022.3/Documentation/ScriptReference/Bounds.Encapsulate.html on them all

[charred spoke]

Depending on the size of his point cloud that could get expensive

hello @everyone, i am creating a 3d chess game, and rn i am only at the beginning, and i am trying to, when i hover my cursor on a tile (that i created via script) it changes layer, like from( tile ) to (hover) and then comes back to (tile) when i remove my cursor from that tile. My problem now is that it isnt working even tho i got no console error and i think that my script is good. Maybe i need to add something to it idk: here is the part of my script:
private void Update()
{
if (!currentCamera || !boardActive //IS A BOOLIAN)
{
currentCamera = Camera.main;
return;
}

    RaycastHit info;
    Ray ray = currentCamera.ScreenPointToRay(Input.mousePosition);
    if (Physics.Raycast(ray, out info, 100,  LayerMask.GetMask("Tile", "Hover")))
    {
        //GET THE INDEXESOF THE TILE I'VE HIT
        Vector2Int hitPosition = LookUpTileIndex(info.transform.gameObject);

        //IF WE'RE HOVERING A TILE AFTER NOT HOVERING ANY TILE
        if (currentHover == -Vector2Int.one)
        {
            currentHover = hitPosition;
            tiles[hitPosition.x, hitPosition.y].layer = LayerMask.NameToLayer("Hover");
        }

        //IF WE WERE ALREADY HOVERING A TILE, CHANGE THE PREVIOUS ONE
        if (currentHover != hitPosition)
        {
            tiles[currentHover.x, currentHover.y].layer = LayerMask.NameToLayer("Tile");
            currentHover = hitPosition;
            tiles[hitPosition.x, hitPosition.y].layer = LayerMask.NameToLayer("Hover");
        }
    }
    else
    {
        if (currentHover != -Vector2Int.one)
        {
            tiles[currentHover.x, currentHover.y].layer = LayerMask.NameToLayer("Tile");
            currentHover = -Vector2Int.one;
        }
    }
}

[simple hawk]

I created code to instantiate a bullet prefab, but how can I make a custom rotation for it? right now, it spawns according to this player rotation, which is horizontal, but I want it to be vertical.

public class shootTest : MonoBehaviour
    
{
    [SerializeField] private GameObject bulletPrefab;
    // Start is called once before the first execution of Update after the MonoBehaviour is created
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space))

        {
            Instantiate(bulletPrefab, transform.position, transform.rotation);
                
                }
            
        
}}

[simple hawk]

not sure I did that right

[keen dew]

Instead of using the player rotation when instantiating, use whatever rotation you want

[hexed terrace]

you did not, use 3x `

Instantiate(bulletPrefab, transform.position, **theRotationYouWantItToBe**);

[simple hawk]

I'm probably doing this wrong, but now it's saying that no overload for instantiate takes 5 arguments

[keen dew]

Yes because you just added 3 zeroes instead of a rotation

[simple hawk]

yea, I'm super confused on how it should be set out

[naive pawn]

it needs a quaternion (as the hover message shows), not 3 euler angles or whatever you've tried to set there

[keen dew]

You can do something like Quaternion.Euler(0, 0, 0) to get a rotation

[naive pawn]

also why do you want a bullet to be vertical if you're presumably trying to shoot it

[keen dew]

but if this is confusing it might be best to go through !learn beginner courses again

[rigid kite]

Hello guys. I want to make a circle like this. And I want it to be Collider sensitive. How can I do that?

[simple hawk]

just looks better, I'm fine if I can't get it to work (not the end of the world), but it'd look nice

[naive pawn]

a bullet being vertical looks better than a bullet actually pointing in the direction of travel?

is your mesh misaligned or something?

[naive pawn]

you add a collider

[hexed terrace]

If you're not doing this by code, you're in the wrong channel.. delete and ask in #🖼️┃2d-tools

[rigid kite]

Wow super clever man how can i forgot about it

[rigid kite]

Sorry, thanks for help

[simple hawk]

vertical as in it goes in the direction of the barrel

[naive pawn]

that would be horizontal

or do you mean when looking up?

sounds like you'd want the rotation of the camera, not the player

[simple hawk]

game is in top down view, I may be getting my words mixed up

[naive pawn]

yeah you definitely need to give more context here

what exactly is the issue you're having?

[hexed terrace]

put an empty transform as a child of the gun. Rotate it so that the Z forward is pointing along the barrel of the gun and at the end of it.

Spawn the bullet at the same pos/ rotation as this transform.

err... might not be Z forward on top down... X instead?

[simple hawk]

that probably would have made my life much easier, I just made the gun a part of the player sprite

[hexed terrace]

the gun can remain part of the player sprite

[simple hawk]

this worked, thnx for the help

[rigid kite]

public GameObject gun;
public GameObject bulletPrefab;

public void Shoot()
{
  GameObject spawnedBullet = Instantiate(bulletPrefab);
  spawnedBullet.transform.forward = gun.transform.forward;
}

//Or if your game is top-down

public void Shoot()
{
  GameObject spawnedBullet = Instantiate(bulletPrefab);
  spawnedBullet.transform.up= gun.transform.up;
}

try to do this

[hexed terrace]

don't use public fields
assign the position and rotation when instantiating, not on a separate line

[keen dew]

that won't even set the position

[rigid kite]

Every time I do this, it works. What is the problem with tihs?

[naive pawn]

please don't spoonfeed

[rigid kite]

I am just talking about the rotation

[naive pawn]

it's not that it doesn't work, but if you get recommendations, you'd want them to be good recommendations, right

[rigid kite]

If he dont know the meaning of the code he can basically ask

[keen dew]

Yeah but fixing the rotation isn't very useful if the solution breaks setting the position

[naive pawn]

and spoonfeeding discourages that

[hexed terrace]

It works, but it's bad/ beginner code.

You don't want public fields, because nothing outside of this class should have direct access to those fields, if you want them visible in the inspector use [SerializeField] private <type> myVariable;
The instantiate method has overloads, specifically for setting the position and rotation when you spawn the object, so it can be put in the correct position / rotation (etc for the other overloads), and not spawn at 0,0,0 then jump to whatever position and rotation you set after spawning it.

i dont want something to happen when i click but something to happen when i ONLY put my cursor on the game object

[rocky canyon]

its really curious how u dont have errors.. when the script u sent is broken

[gloomy hamlet]

i just added it when i was sending you the script

[naive pawn]

we can tell it's a boolean by the way it's used in an if

[rocky canyon]

ahh,, well add the //comment after the )

or u break the if statement

[gloomy hamlet]

only cuz i didnt send

private bool boardActive;

.....

[naive pawn]

or use a /* boolean */ block comment

[rocky canyon]

you can tell by the way that it is.. 😂
🌲 humor

[gloomy hamlet]

how do i do it

[naive pawn]

the boolean knows where it is because it knows where it isn't

[rocky canyon]

        if (!currentCamera || !boardActive) //like this
        {
            currentCamera = Camera.main;
            return;
        }```or 
```cs
        if (!currentCamera || !boardActive /* like this */)
        {
            currentCamera = Camera.main;
            return;
        }```

[gloomy hamlet]

ok wait a sec

[rocky canyon]

that clears up the compile error u may or may not have. (unsure)
but that doesn't solve ur main issue (unless it does)

[gloomy hamlet]

still the same

the layer doesnt change

[rocky canyon]

u need to use some log statements

[naive pawn]

how exactly isn't it working? is it not hovering? is it not going back?

[gloomy hamlet]

when i hover my cursor on the game object

[rocky canyon]

put them in ur raycast see if its hitting anything/ what its hitting/ when its not hitting

[gloomy hamlet]

the layer doenst change i put my cursor on the tile even tho it should

i can send the entire code if you guys want but the rest is all about generating the tiles

[naive pawn]

put some logs - is the raycast being reached, is it passing, is some other conditional not passing?

etc

[rocky canyon]

if (Physics.Raycast(ray, out RaycastHit info, 100f, LayerMask.GetMask("Tile", "Hover")))
{
    Debug.Log("Raycast HIT: " + info.transform.name + " on layer: " + LayerMask.LayerToName(info.transform.gameObject.layer));
    ...
}
else
{
    Debug.Log("Raycast MISS");
}```

u can log when u change the layer to confirm that happens..

so on and so on the more u know the better

im guessing its probably a layer / mask issue

for example is the tile actually on the tile layer...
(like if the collider was a child object) it could be missin

[gloomy hamlet]

yea i tried it but the console says that the hitPosition does not exist

[gloomy hamlet]

absolutly everything is made in the script

the tile the collider etc

[rocky canyon]

Vector2Int hitPosition = LookUpTileIndex(info.transform.gameObject); possibly this is broken somehow then

or in the LookUpTile function

send logs to urself in those methods and see if its outputting what it should

[gloomy hamlet]

private Vector2Int LookUpTileIndex(GameObject hitInfo)
    {
        for (int x = 0; x < TILE_COUNT_X; x++)
            for (int y = 0; y < TILE_COUNT_Y; y++)
                if (tiles[x, y] == hitInfo)
                    return new Vector2Int(x, y);
        
        return -Vector2Int.one; // -1 -1
    }

[shut swallow]

for hitboxes in my game with timestop, is it better if I store the hit and apply the effects after time has been resumed or if I instansiate a collisionbox alongside my Visual Effect object

[rocky canyon]

show a screenshot of one of the tiles selected in play-mode and its inspector visible

[gloomy hamlet]

k wait

[rocky canyon]

what type of problems are u expecting to avoid by using one over the other?

[rocky canyon]

what concerns do u have to be debating the two?

[rocky canyon]

well, i see the problem

[gloomy hamlet]

which is?

[rocky canyon]

how do you think raycasts work?

what it is that causes a raycast to log a hit?

[gloomy hamlet]

like an invisble line

[rocky canyon]

whats it hitting do you know?

[gloomy hamlet]

what do you mean?

pls get straight to the point 😭

[rocky canyon]

a raycast hits a collider

ur tiles have no collider

so.. no raycast can ever detect them

[gloomy hamlet]

Vector2Int hitPosition = LookUpTileIndex(info.transform.gameObject);

to this maybe?

Vector2Int hitPosition = LookUpTileIndex(info.collider.gameObject);

[rocky canyon]

thats using the info variable..

which is hit info the raycast outputs

but thats if the raycast detects a collider...

ur raycast is never hitting any of those tiles

u dont need to change ur code.. u need to fix ur tiles

[gloomy hamlet]

so i need to change info to hitInfo?

[gloomy hamlet]

do i send you the tile generation code?

[shut swallow]

for using a boxcast mostly to save resources and not needing to spawn a collision box, for spawning hitboxes it's for better interactions (e.g. when I want to have things moving in timestop as a mechanic)

I'm thinking of if using a boxcast will make my life easier because registrating the hit while the VFX is still playing is fine, any onhit effect I can delay them until after time has resumed

[gloomy hamlet]

i dont even have a collider in my tiles

[rocky canyon]

ya, thats the problem

[gloomy hamlet]

wait a sec

i went to my code and i saw this:

tileObject.GetComponent<BoxCollider>();

i fixed it

tileObject.AddComponent<BoxCollider>();

but it still doesnt work

[rocky canyon]

if time truely stops for everything i feel raycasting could be easier and cleaner

if not and theres reasons to have immediate hit detections /visual feedback id do the latter

[rocky canyon]

well no go back in the game- run it and see if they have colliders

[gloomy hamlet]

they do

[rocky canyon]

then add logs in ur raycast to see if ur hitting them..

[gloomy hamlet]

wait

should they have box collider or mesh collider?

[rocky canyon]

it doesnt really matter..

[shut swallow]

I'm thinking of making some bosses ignore timestop for the funnies

[gloomy hamlet]

ok thx

[shut swallow]

but realistically I don't have time for it before I need to push this out for my profolio entry for uni

[rocky canyon]

you'll just want to Log the hit variable of ur raycast

and even put one in the if and the else Raycast succeeded Raycast Failed

[shut swallow]

for a second I thought you were responding to me lol

[gloomy hamlet]

look man i am not a pro at this just a beginner

[rocky canyon]

i understand that.. and these are the most basics of concepts..

logging is 1 of the first things u should learn

[shut swallow]

also a question on this: is physics.raycast not instant?

[rocky canyon]

it occurs on the next physics frame (FixedUpdate()) i believe

edit: my mistake.. Physics "Raycasts" are just checks not physics-driven forces or any of the like..
therefor they are practically "instant".. If you call a raycast in update it'll run a check every frame

[shut swallow]

I feel like the latter will be better then, gives more control over behaviour

[gloomy hamlet]

can you send all the refenreces for like: rayDistance queryTriggerInteraction, etc

[rocky canyon]

  if (Physics.Raycast(ray, out info, 100, LayerMask.GetMask("Tile", "Hover")))
    {
        Debug.Log("Raycast succeeded");
        Debug.Log(info.transform.name);

        // GET THE INDEXES OF THE TILE I'VE HIT
        Vector2Int hitPosition = LookUpTileIndex(info.transform.gameObject);
        Debug.Log(hitPosition);
        ...
    }
    else
    {
        Debug.Log("Raycast failed");
        ...

    }```
https://gamedevbeginner.com/how-to-use-debug-log-in-unity-without-affecting-performance/

[rocky canyon]

no, you already have ur raycast written out. its simple as putting LOGS inside what u have..

and see if it runs.. and if it doesn't.. if it does u send info thats useful to figure out what in the code isnt returning the results ur expecting.. or running at all)

[rocky canyon]

ya, i use raycasts for everything so im a bit biased

but the collider method sounds fine too

[gloomy hamlet]

absolutly nothing works

i feel like my brain wants to implode

i am about to give up on this project

[rocky canyon]

i personally feel like u bit off more than u can chew.. and need to take a step back..
for example first writing a simple raycast.. have it hit a cube directly in front of it.. see what works and what doesnt.. log that information in the console.. take in, take notes, then u grow.. expand.. and add more and more slowly

[shut swallow]

how do you exclude all collision layers except one for colliders? When initiated do they default to collide all or no layers?

[gloomy hamlet]

i did that

i spent the entire moring working on this

[rocky canyon]

well once u had it working with a cube.. u coulda made it work with a tile

once u had it working with a tile.. u could add in the layers..

[shut swallow]

to took me more than a morning to even comprehend the input system lol chill

[rocky canyon]

so and so on.. my point still stands.. ur biting off more than u can chew.. and resolving ur issue is going to be more frustrating for you and the helper than needs be..

im being generous too. most other guys will just send you the !learn links and tell you to go back to the basics

[shut swallow]

Read documentation it helps a lot

[gloomy hamlet]

imma try again

[rocky canyon]

for example i bet u unity has tile systems as examples in their documentation

[shut swallow]

also this

[sour fulcrum]

Unity’s tile stuff is kinda mid for what most beginners will want

[gloomy hamlet]

they all get the (tile) layer

[sour fulcrum]

What do you mean by this

[hexed terrace]

Not a question for this channel.. but, a collider uses the layer of the gameobject to know what it can collide with. You set which layers can collider in the collision matrix

https://docs.unity3d.com/6000.1/Documentation/Manual/LayerBasedCollision.html

[shut swallow]

oh sorry that was me asking a question lol

[shut swallow]

oh mb, could you redirect me to which channel I should ask in so I know next time?

[hexed terrace]

id:browse -> read the channel topics

[shut swallow]

    {
        Physics.BoxCast(
            center: castCenter,
            halfExtents: vector3HalfExtents,
            direction: slashDirection,
            hitInfo: out _meleeHitRegister
            );
        return;
    }``` bit of a stupid question: is this correct syntax?

does returning this gives a boolean?

[hexed terrace]

If your IDE is setup correctly, it will tell you of any compile / syntax errors.

you're not returning anything there.

void - means the method doesn't return anything, so your return at the end there does nothing, removing it and you're doing the same thing.

[shut swallow]

ah, any reason why it's void instead of a bool like it's supposed to?

[hexed terrace]

because your wrote it like that?

[shut swallow]

I'm sorry isn't BoxCast() supposed to return a bool?

[hexed terrace]

It does.

You are not doing anything with that bool.

[shut swallow]

I just want to store it

[hexed terrace]

you have the documentation open, the documentation has example code

[thorn holly]

bool b = BoxCast()

[thorn holly]

If you’re trying to return the Physics.BoxCast(…) then change the return type from void to bool and say return Physics.BoxCast(…)

[shut swallow]

ah ok this makes sense

[rocky canyon]

https://streamable.com/6jc4km here's a vid clip i made laying out the process you probably need to take..

• make simple raycast, raycasting using mouse position and main camera (test and confirm)
• make tile prefab setup to work w/ raycast (collider and layer assignment) (test and confirm)
• simply use the raycast overload that can accept a layermask, assign the 'Tile' layer or w/e layer u chose for the tiles to this layermask in the inspector (test and confirm)

if u stop and test along the way you end up with smaller problems with easier solutions..
than if u wait until the end and realize it doesn't work.. but unsure why or how it became that way

[lilac cape]

Is anyone free to help troubleshoot an object interaction?
In my player controller script I have:
Getting these debug messages

  {
    playerInteraction.TryInteract();
    Debug.Log("Interact action performed");
  }

Getting these debug messages as well

using UnityEngine;

public class PlayerInteraction : MonoBehaviour
{
  Transform _transform;
  [SerializeField] LayerMask interactableLayer;

  void Awake()
  {
    _transform = transform;
  }
  public void TryInteract()
  {
    Debug.Log("Attempting to interact...");
    if (!Physics.Raycast(_transform.position + (Vector3.up * 0.3f) + (_transform.forward * 0.2f),
     _transform.forward, out RaycastHit hit, 3f, interactableLayer)) return;
    
  }
}

For some reason I'm not getting anymore debug messages: My SingleDoorControl script

using UnityEngine.Events;

public class SingleDoorControl : MonoBehaviour, IInteractable
{
  private Animator animator;
  private bool isOpen = false;
  private bool openedForward = false;

  [SerializeField] private Transform playerTransform;
  [SerializeField] private Transform doorForwardReference;

  void Awake()
  {
    animator = GetComponent<Animator>();
  }

  public void Interact()
  {
    if (!isOpen)
    {
      Debug.Log("Door was open and tried to open");
      Vector3 toPlayer = (playerTransform.position - transform.position).normalized;
      float dot = Vector3.Dot(doorForwardReference.forward, toPlayer);

      if (dot >= 0)
      {
        animator.Play("SingleDoorOpen_Backward");
        openedForward = false;
      }
      else
      {
        animator.Play("SingleDoorOpen_Forward");
        openedForward = true;
      }

      isOpen = true;
    }
    else
    {
      if (openedForward)
        animator.Play("SingleDoorClose_Forward");

      else
        animator.Play("SingleDoorClose_Backward");

      isOpen = false;
    }
  }
}

My interactable object and iinteractable scripts:

using UnityEngine;
using UnityEngine.Events;

public class InteractableObject : MonoBehaviour, IInteractable
{


  [SerializeField] private UnityEvent _onInteract;

  public void Interact()
  {
    Debug.Log($"Interacted with {gameObject.name}");
    _onInteract.Invoke();
  }
}

using UnityEngine;
using UnityEngine.Events;

public interface IInteractable
{
  // public UnityEvent Interact { get; protected set; }
  public void Interact()
  {
    Debug.Log("Interact method called on IInteractable");
  }
}

My player and door have the following components:

Let me know if there is anything else I can provide that would be helpful 🙂

I'm thinking the problem might lie somewhere on my player interaction script. Maybe it's not called the Interact right?

Door is on the intractable layer

[hexed terrace]

you say you don't get any logs, and then the next code block doesn't have any logs in it

[eager elm]

I mean, you don't do anything in TryInteract(), you either return or do nothing

[hexed terrace]

your PlayerInteraction class doesn't actually call any interaction.. it's just raycasting looking for an interactable layer

[lilac cape]

Ahh you're right Gruhlum, I added a debug message inside this method and I do see the debug message in the console:

public void TryInteract()
  {
    Debug.Log("Attempting to interact...");
    if (!Physics.Raycast(_transform.position + (Vector3.up * 0.3f) + (_transform.forward * 0.2f),
     _transform.forward, out RaycastHit hit, 3f, interactableLayer))
    {
      Debug.Log("No interactable object found in range.");
      return;
    }
    else
    {
      return;
    }

  }

[hexed terrace]

right.. but you're not doing anything... you're not getting the component to call the interact method on it. Methods don't run if you don't call them.

[eager elm]

see if "hit" has a Component of Type IInteractable and then call Interact() on that component

[lilac cape]

Something like this?

public class PlayerInteraction : MonoBehaviour
{
  Transform _transform;
  [SerializeField] LayerMask interactableLayer;

  void Awake()
  {
    _transform = transform;
  }
  public void TryInteract()
  {
    Debug.Log("Attempting to interact...");
    if (!Physics.Raycast(_transform.position + (Vector3.up * 0.3f) + (_transform.forward * 0.2f),
     _transform.forward, out RaycastHit hit, 3f, interactableLayer))
    {
      Debug.Log("No interactable object found in range.");
      return;
    }

    // Get the IInteractable component and call Interact()
    var interactable = hit.collider.GetComponent<IInteractable>();
    if (interactable != null)
    {
      interactable.Interact();
      Debug.Log("Interact called on: " + hit.collider.name);
    }
    else
    {
      Debug.Log("Hit object is not interactable: " + hit.collider.name);
    }
  }
}

Just tested and only getting to the attempting to interact debug message

[rocky canyon]

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

        if(Physics.Raycast(ray,out RaycastHit hit,distance,mask))
        {
            if(hit.collider.TryGetComponent(out IInteractable interactable))
            {
                cachedInteractable = interactable;
                cachedTransform = hit.transform;
                cachedHitPoint = hit.point;

                if(Input.GetKeyDown(interactKey))
                {
                    cachedInteractable.Interact();
                    Dbug.Italic($"Interacted with {cachedTransform.name}");
                }
            }
            else
            {
                ClearCache();
            }

            draw = true;
        }
        else
        {
            ClearCache();
            draw = false;
        }
    }``` heres how mine looks if it helps any..

[eager elm]

if you don't see "No interactable object found in range." than that means that you found an object but it doesn't have an IInteractable Component

[rocky canyon]

i also log the cachedTransform in the inspector.. makes me feel better for some reason lol

[rocky canyon]

raycast must fail then no?

[eager elm]

well, something isn't right tho, because you should either way get one more Debug massage

[rocky canyon]

-check layermask
-check ur actual raycasting position and direction
-check that the object is in range and not blocked by something else
-check that the object has a collider and its not on a child or something else

do what i did ^ and just log the hit info in the console or inspector at first.. make sure its detecting the thing that has the component..

and that u dont have to retrieve it from up or down its hiearchy

[lilac cape]

So on my player gameobject, I changed the player interaction serialized field to Player Interactio and the door is opening now. Originally I had this set to playerinteractionmanager. Is it better to try and set unity events up in a manager? Sorry if this question is badly worded. Just started learning how to set up more scalable unity events yesterday..

[median hatch]

whats your goal?

[lilac cape]

Visual view:

[median hatch]

to open a door?

[lilac cape]

Honestly to have a system that makes it easier to add future events like picking up object, throwing things, interacting with different object with different results, etc

[rocky canyon]

well the goal would be bigger than that. if they're doing an Interactable Interface

[median hatch]

instead of events i'd recommend interfaces then

interfaces are perfect for this

you make an IInteractable interface

and objects that are interactable can have different behaviours

[rocky canyon]

ya, interfaces w/ trygets is my jam 🪕

[lilac cape]

I'll have to look into interfaces. What were y'alls favorite resources while learning how to use them?

[rocky canyon]

tbh interfaces were trial and error + friends help

basically its just this tho

and then anything that inherits just has to have that Interact() method

and for a pickup:

[lilac cape]

Then you just have a super long switch statement? Somethign that has all the interactions?

[rocky canyon]

well the switch is only b/c my switch class can function 3 different ways

like toggle, push to start, etc

[lilac cape]

ahh, nice

[rocky canyon]

u just call the function with the Interactable Raycaster or w/e

my raycast doesn't really care if its a pickup, a switch, any kind of action..

it only has to call .Interact()

[lilac cape]

What confuses me the most is when linking interact() with the method that does the action. I feel like seeing Interact() everywhere confuses me but I like the benefit lol

[rocky canyon]

if its an IInteractable -> then it must have an Interact() method..
if it has an Interact() method.. i'll just call it.. theInteractableYouHaveSelected.Interact();

[eternal needle]

The class implementing the interactable interface handles the interaction. Interfaces are specifically to avoid having one giant method handling every single interaction

[median hatch]

public class TunaCan : MonoBehaviour, ICollectible
{
    [SerializeField] PlayerController playerController = null;
    [SerializeField] bool isMovingToPlayer;
    [SerializeField] bool isCollected;

    public static event Action OnCollectTunaCan;

    // Update is called once per frame
    void Update()
    {
        if (isMovingToPlayer)
        {
            transform.position = Vector3.MoveTowards(transform.position, playerController.transform.position, UnityEngine.Random.Range(0.1f, 0.2f));
        }
    }

    public void Collect(PlayerController playerController)
    {
        this.playerController = playerController;
        isMovingToPlayer = true;
    }

my code is simpler

using UnityEngine;

public class Collect : MonoBehaviour
{
    void OnTriggerEnter(Collider other)
    {
        if (other.gameObject.CompareTag("Collectible"))
        {
            PlayerController playerController = GetComponentInParent<PlayerController>();

            ICollectible collectible = other.GetComponent<ICollectible>();
            collectible.Collect(playerController);
        }
    }
}

then just a lil script that calls that interface

[lilac cape]

Could you use that Collect class on an any gameObject you want to be collected?

[median hatch]

yea thats the idea

for me anything that is tagged Collectible will have a ICollectible interface

that i can do whatever i want with

[rocky canyon]

🎮 easymode:```cs
if (hitObject.CompareTag("Pickup"))
hitObject.GetComponent<Pickup>().DoPickup();
else if (hitObject.CompareTag("Switch"))
hitObject.GetComponent<Switch>().Toggle();
else if (hitObject.name.Contains("Lever"))
hitObject.GetComponent<Lever>().Activate();

🕹️ skilled-mode:```cs
if (hit.collider.TryGetComponent(out IInteractable interactable))
{
    interactable.Interact();
}```

[median hatch]

in this case collect

it seems a bit weird at first but its one of the most powerful ways of not repeating your code

[lilac cape]

Do you have an interactable layer as well? Are your collectibles on that interactable layer if you do?

[rocky canyon]

no thats the cool thing about them..

[median hatch]

nope

just a Collectible tag and when player goes over them boom

[median hatch]

magic

[rocky canyon]

the fact this script has a Switch that inherits from IInteractable

my raycast just grabs it

i even use Interfaces as tags sometimes

well actually i just use an empty script

but same idea

[median hatch]

arent you hitting any collider and checking if for IInteractable all the time?

[rocky canyon]

well my raycast does raycast all the time yea

but the tryget fails if its not an Interactable

so none of that logic gets run

[median hatch]

just a bit weird, why not put those IInteractable objects in a layer?

[eternal needle]

For systems like this its better if you implement it yourself rather than trying to copy what someone else did. You might want interactions to happen in a different way first off compared to OnTriggerEnter. A lot of people also dont like tags all that much and would rather use layers

[median hatch]

otherwise you're looking at anything and checking for IInteractable constantly

[zenith cypress]

Pretty common and isn't really a problem (I do this in every project that wants interactions).

[rocky canyon]

i can find my interactables pretty easily

and its a way to save tags imo

[median hatch]

ah sounds good then

yea i got a lot of tags...

xD

[rocky canyon]

and i can have more than 1 interface on a Gameobject 😉

[median hatch]

true true

although one should be enough

dont want any race conditions happening

[rocky canyon]

ya, for basic games 1 or 2 is enough for Interactions

[lilac cape]

Is it better to have an interface system when working with inventory systems?

[median hatch]

definitely

[brave robin]

I just don't use tags because something can only have 1 tag, which limits their usefulness
My interactables have a separate object with the trigger collider that exists on an Interactable layer, just for raycasting. But the parent object can be on any layer.

[median hatch]

you see it with minecraft

some objects arent stackable

interfaces are pretty good for that type of stuff

[brave robin]

Interfaces unravel OOP inheritance into something more sane

[median hatch]

yea was honestly one of the best things to learn

the code in general gets so much cleaner

[lilac cape]

are scriptable objects another thing to learn as well? I honestly don't know much about interfaces or scriptables object..yet

[median hatch]

yup

just remember to only store static data in them

they dont save during runtime

[brave robin]

Absolutely, they are very handy as data containers and for compartmentalizing some methods, like RPG skills

[grand snow]

They can also be used for logic in a way you can share easily over many scenes but its easy for it to get unloaded so duplicate instances may be made accidently.

[lilac cape]

That makes sense, maybe it's better to use raycasting instead? Also I just did some research and it looks like using layers might offer performance benefits by excluding certain objects from raycast or collision checks using layer masks

[brave robin]

All the skills, stats, spells, items, traits, monster setups, dialogue, and many other bits of data are scriptable objects in my game

[eternal needle]

you can ask this about any concept in c# and someone will chime in with "it wont hurt to learn". dont get overwhelmed trying to learn everything. look at scriptable objects when you need them. They are just simply data containers.

[median hatch]

i wouldnt worry about performance in the beginning

just make things work

[eternal needle]

you mean immutable data hopefully, static would mean the static keyword

[median hatch]

yea my bad

[brave robin]

The chances of actually noticing bad performance in your game when starting out is pretty negligible. By the time you're doing stuff that hurts performance, you'll have the experience needed to tackle it

[lilac cape]

Ahh thanks, that means I'd have to reload my domain on play because I've heard from somewhere that if you don't reload your domain your static variables won't change or something

[median hatch]

thats different

my point is if you try to save data into a scriptable object the next time you run your game its gone

[grand snow]

(except in editor where its kept cus dumb)

[lilac cape]

I feel like my overwhelmed feeling just turns to excitment because it's another area to learn about this stuff😂

[eternal needle]

yes people often use layers here so you arent trying to get a component (the interface) on every single object. You would use a raycast if you wanted to interact by looking at an object or having your mouse over it

[brave robin]

That's a positive sign you'll enjoy the journey

[median hatch]

i cant imagine the pain and suffering of the people that found this out when their game was ready to ship

[grand snow]

Ha yea, it annoys me more when I want to change a serialized var and i dont expect it to be 'saved'

[lilac cape]

I was watching a video where it caused issues like incorrect save location

[grand snow]

Unity should fix scriptable objects keeping the changes post play to make it clearer its not a thing

surely it can just re apply the saved data after

[brave robin]

If my scriptable object's state is being changed in game, I store a separate value on it which is the Current value. The current value is set to be the same as the initial saved value, and then only the Current one gets modified.

[eternal needle]

that doesnt really make sense by itself. though still, didnt you want to be looking at interfaces for now?

[median hatch]

this could honestly be a feature for a horror game

you change the spawn location var in the SO, next time you reload the game you're at the beginning

[lilac cape]

Yeah I got some tutorials and guides to read up on

[median hatch]

just make sure to take your time

making games is super hard

its normal to get overwhelmed

[eternal needle]

you'll likely learn this quicker outside of unity tbh. if you've done your c# basics first then itll be no problem. Find any tutorial that talks about some animals interface, then makes a cat dog and puts them all in the same array and boom its solved. Then try to extend that to your own kind of class

there isnt much to learn about interfaces

[lilac cape]

Yeah right now I just have dev_playground project and I'm just tackling random things like making doors open both way or picking up cubes. If I need a quick idea I usually just as AI for something to build out. Once I found out how much goes into player movement it made me appreciate games a LOT more becuase players don't see what makes a game, a game

[median hatch]

yea that goes with most industries

[zenith cypress]

It's not dumb, and makes sense. In the editor, if you don't instance the SO before modifying it, then you are directly modifying the asset itself. In a built game it basically just loads the SO from the game's resources each time you boot the game, which doesn't change since there are no "assets" anymore.

[median hatch]

once you start diving into it you realize how deep the rabbit hole goes

[grand snow]

I know, which is why unity adding a mitigation would be a good idea

[lilac cape]

It never ends haha. When you think it does the next editor verison comes out..

[rocky canyon]

even if there weren't any new releases from now on.. it'd be unlikely u'd still know everything there is to know

and theres some things u never need to know..

im building a 3D game.. i don't need to know how the tilemap system works

only master nerds know everything bout the entire engine 😈

[lilac cape]

One of my goals is to get suuuper good at unity so that by the time Unity 7 alpha gets released (late 2026 or 2027), I can start making guides on how to use it and hopefully even a course. That was one of my biggest OCD complaints when learning because I'd be on unity 6 but the guide was using 2019. Even those there should be compatibilities, just having a guide that uses the version your on is just helpful. Making a course would also hopefully expose me to Unity areas I hadn't seen before so it's another reason I'd want to tackle something like that.

[lilac cape]

I built a 2d brick breaker game using assets I made from Aseprite to learn how to integrate the two. Was a fun little project that didn't take too long. Also helped with learning about asset scaling

Also @simple hawk any luck on learning the new input system? This was a really helpful video that I used to help learn the system. After watching the tutorial I first studied how each part connected to eachother and then I just kept trying to make my own input system basic control scheme from scratch until I could make it without really needing to glance at the completed code:
https://www.youtube.com/watch?v=Yjee_e4fICc&t=60s

[scarlet skiff]

ok so i have an enemy that i want to stop moving for a bit every now and then, i already got the logic for when it stops moving, to wait a bit before mvoing again, but for stopping movement, can i just start such a coroutine inside start()?

private IEnumerator ResetWalkWaitTimer(float wait)
{
      yield return new WaitForSeconds(wait);
      float delay = Random.Range(5f, 10f);
      waitBeforeWalkTimer = 0f;
      StartCoroutine(ResetWalkWaitTimer(delay));
}

[rich adder]

you can just use a while loop tbh

and probably even make Start itself the coroutine (unless you call ResetWalkWaitTimer at later time)

[acoustic belfry]

Hi, what would be better for move a dynamic rigid object to follow another actor and to move side to side
linearvelocity or addforce?

also, how i can make an int of a script be private but only be accesible for the children of that script? When i make it privated its childrens can't interact with it

[rich adder]

wdym by "children of that script"

are you talking about inheritance or components in other gameobjects
also linearvelocity or addforce both move the rigidbody properly, addforce takes mass/friction other physics attributes into account, velocity doesn't

[polar acorn]

https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/access-modifiers

[acoustic belfry]

i just want it to walk, without phasing thought physics

and i mean inheritance, i forgot the word in english for heredero wich is inheritance i think, thanks
yeah, inheritance

nop, my english is bad, is not heredero, is herencia, but yeah, that thing is

[rich adder]

check the link posted above , you can use protected or private protected

[acoustic belfry]

ooh, interesting, thanks :3

[acoustic belfry]

what about rb2d.MovePosition?

i just want it to chase an object without glitching or phasing tru walls

[rich adder]

then don't use MovePosition, its meant for kinematic movement and will def phase through walls

[acoustic belfry]

got it, so i should use linearvelocity or i should use addforce? i mean wich one would be cleaner

[rich adder]

idk what you mean "cleaner" I kinda already pointed out the differences, see which one fits your need

they are both good methods, different "feel"

[acoustic belfry]

I think velocity is simplier. Cuz i dont need friction and others to be calculed, thanks :3

[acoustic belfry]

how i can fuse functions between inherites?
I mean, i have that in the baseScript update it flips depending on a value transform.localScale = new Vector3(-1, 1, 0); , and i want the InheritedScript update to do the same and play an animation clip animator.Play("Base Layer.MortemRifleSight"); but without having to write the flipping part that belongs to the base, how i can do so?

i know how to replace, using overdrive, but i dont know how to fuse

[naive pawn]

you mean override?

you can call the base method with base.Method

class A {
  public virtual void Print() {
    print("A");
  }
}

class B : A {
  public override void Print() {
    base.Print();
    print("B");
  }
}

new B().Print(); // prints `A` then `B`

[short hazel]

Yeah if you have that in Update, Unity won't call the base class' Update so you have to do it yourself by making it virtual and calling it from the override

[vocal wharf]

General question here. If I have two variables (int type) that are set to different values and I write an equality statement such as
numberA = numberB
does numberA get set to the value of numberB or vise versa? Basically which order does Unity use?

[short hazel]

The value of numberB gets copied into numberA

Right-to-left for assignments with =

[acoustic belfry]

ooooh, thanks

i was replacing my old enemy movement with a new one that uses their rigidbodies....but i discovered an issue.........................why my enemies fly?

                mortemRb.linearVelocity = direction * runSpeed;```

[naive pawn]

that's not an equality statement in the programming world, btw - that's an assignment, and it's always "set x to y" for some x = y
field initializers use the same syntax - float speed = 8 or whatever

[vocal wharf]

ah yeah makes sense thanks

[naive pawn]

it's analogous to := in math, as in x := y -> "let x be equal to y"
some languages use := for assignment, but most just use =

[acoustic belfry]

i dont get why they fly

[naive pawn]

are you doing sidescroller or top-down?

[lilac cape]

Are you using AddForce? What does the code look like

[acoustic belfry]

 mortemRb.linearVelocity = new Vector2(direction.x * runSpeed, mortemRb.linearVelocity.y);```

now i fix it

they no longer fly

ths was the bad script

                mortemRb.linearVelocity = direction * runSpeed;```

[naive pawn]

yeah thought so

[acoustic belfry]

but, now i have another problem

[naive pawn]

though this means it'll run slower if they aren't at the same elevation

instead of normalizing the vector, you'd want to normalize just the x value
you can use Mathf.Sign/Math.Sign for that (depending on what you want to happen if they're perfectly inline vertically)

[acoustic belfry]

oh

how i can fix it then?

[vocal wharf]

Is there a way to exclude a single item when using Random.Range to select from an array? I have a string array (six individual letters of the alphabet) and I'm trying to randomly generate one after the other without repeating the previous letter that was generated. I tried assigning a "lastMove" integer to the last array item that was picked and checking if the current item number matches the "lastMove" number using an if/else statement but this doesn't work if the random number is identical twice in a row. Any ideas would be appreciated.

here is the script if needed. Useless context: it's a Rubik's Cube random scramble generator and I'm trying to generate 20 random letters consecutively (each letter in the array stands for turning a certain face on the cube).

public class NewScramble : MonoBehaviour
{
    public TextMeshProUGUI scramble;
    private string[] possibleMoves = {"R", "L", "U", "D", "F", "B"};
    private string[] moves = {"1", "2", "3", "4", "5", "6", "7", "8", "9", "10", 
        "11", "12", "13", "14", "15", "16", "17", "18", "19", "20"};
    private int moveSelector;
    private int lastMove;
    void Start()
    {
        GenerateNewScramble();
    }

    public void SelectNextMove()
    {
        moveSelector = Random.Range(0, possibleMoves.Length);
    }
    public void GenerateNewScramble()
    {
        SelectNextMove();
        lastMove = moveSelector;
        moves[0] = possibleMoves[moveSelector];
        SelectNextMove();
        if (moveSelector == lastMove)
        {
            SelectNextMove();
            lastMove= moveSelector;
            moves[1] = possibleMoves[moveSelector];
        }
        else
        {
            lastMove = moveSelector;
            moves[1] = possibleMoves[moveSelector];
        }

    }
}

The text object reference hasn't been used yet because I'm trying to figure out this part first

[naive pawn]

well you want to keep going until you get something that isn't the previous move, right?

that'd be a loop, not a conditional

[wintry quarry]

the correct way to do this is to put them in a list or array and shuffle it, then iterate over the shuffled items

[acoustic belfry]

also, i made an if statement that if the distance is less than x value, it should stop, it worked when i used the transform.position, but not with the rigidbody

{
    if (distanciaAbsoluta > rangoDisparo)
    {

        animator.Play("Base Layer.MRifle_Walk");
        Vector2 direction = (objetivo.position - transform.position).normalized;
        mortemRb.linearVelocity = direction * runSpeed;
        bullettimer -= Time.deltaTime;
        if (bullettimer <= 0)
        {
            bullettimer = firingspeed;
            disparar();
        }
    }
    else
    {
        bullettimer -= Time.deltaTime;
        if (bullettimer <= 0)
        {
            bullettimer = firingspeed;
            disparar();
        }
    }

}```

[naive pawn]

this wouldn't really work for the usecase though

[vocal wharf]

yes. I thought of that but I didn't know if that was possible (I'm not very experienced in coding lol)

[wintry quarry]

maybe I don't understand the use case

[naive pawn]

a loop is like the very next step up from a conditional

[vocal wharf]

I can't repeat the same letter twice in a row

[naive pawn]

you might want to step back and learn about programming fundamentals first rather than stumbling through code

see pinned resources

[vocal wharf]

sorry I misspoke. I know what a loop is but I didn't know a way to implement it in C#

[naive pawn]

it's not just shuffling the various moves, the output length should be able to be greater than 6

[naive pawn]

then you should go find out how to do it in c#, see pinned resources

additionally - with how you've written it, you can't get R as the first move, you should probably check that

[wintry quarry]

I don't know anything about rubik's cubes so I don't understand what the goal is here really

so I'll back off

[acoustic belfry]

how i do that?... But also... isn't that how it should work? i mean, they slow when im up of them, cuz is like i were in the middle of them, or how?

i dont know, i just want them to chase the player and feel nice, but only chase it until the distance is x

[naive pawn]

also you probably should not have that moves array literal, you can just do new string[20] for an empty array
but a list would probably make it much easier

[naive pawn]

the goal is to shuffle the cube with a random sequence of moves, rather than shuffling the sequence of moves

[naive pawn]

i have no idea what you're trying to say in that first sentence

[naive pawn]

@vocal wharf this was intended for you btw, in case you missed it

[acoustic belfry]

mmm

i dont get, what happens if im higher?

i got lost

[acoustic belfry]

but anyways i feel like this might be more important

[naive pawn]

in these 3 scenarios, should the chase speed be the same

[acoustic belfry]

oh now i get it, i guess it will

sorry

so...how i can fix this?

(i fixed the radius issue, i just had to put mortemRb.linearVelocity = Vector2.zero)

[naive pawn]

if you normalize the entire vector and then get just the x value, the x value's magnitude will be <= 1
you'd want it to be == 1 for a consistent speed, regardless of vertical offset

[vocal wharf]

the moves array is intended to be exactly 20 moves long every time and I'm trying to randomly assign a letter to each item in that array (without repeating a letter twice) and display those letters on screen with a text object. The only point of the moves array is to make things simpler so I can just add all the letters together in the text line easier.

[naive pawn]

this is how you'd fix it @acoustic belfry

[acoustic belfry]

but i mean, speficitly

[naive pawn]

the moves array won't necessarily make it simpler though

actually i think you missed what i'm referring to

a list is similar to an array, just used differently

[naive pawn]

i was quite specific there

[acoustic belfry]

Ok

Sorry if i btw sounded rude...

Well, thanks

[vocal wharf]

The scramble will always be 20 moves long. I read online that lists are used when the number of elements is unknown/changing and arrays are used when the number of elements is fixed. Shouldn't I use arrays then?

[naive pawn]

lists aren't restricted to when the number of elements is unknown

[vocal wharf]

I'm not sure how it would make things easier though

[naive pawn]

if you treat the "amount of moves already generated" as the number of elements changing, you now no longer need to keep track of how many moves have been generated

if you used an array, you would have to keep track separately (or more realisitcally you could use a for loop)

with a list the flow becomes more flexible since the loop would no longer be bound to the amount of elements stored

[vocal wharf]

hmm ok I'll look into it

[naive pawn]

here's 2 possible ways you could do it with an array:

moves = array[20]
generated = 0
while generated < 20:
  nextmove = randommove()
  if generated == 0 or nextmove != array[generated - 1]
    array[generated] = nextmove
    generated += 1
``````py
moves = array[20]
for i in 0..19
  do
    nextmove = randommove()
  while i != 0 and nextmove == array[i - 1]
  moves[i] = nextmove
```how you could do it with a list:
```py
moves = list
while moves.length < 20
  nextmove = randommove()
  if moves.length == 0 or nextmove != moves.last
    moves.add(nextmove)

with the array approach, you have to manage moving through the array yourself - which isn't bad in itself, but IMO using a list gives a much clearer flow for logic

[vocal wharf]

I'll try it thanks

[acoustic belfry]

like this, right?

float directionX = Mathf.Sign(direction.x);
mortemRb.linearVelocity = new Vector2(directionX * runSpeed, mortemRb.linearVelocity .y);```

[naive pawn]

yeah

[acoustic belfry]

nice

thanks ✨

[rapid laurel]

for those who have problems with firebase in the future like me, the problem was that I had to download the google.services.json again and import it because something had changed, I don't know why, but now it works.

[vocal wharf]

I tried recreating the lists example you gave me but I can't figure out what goes where. Does all of this go in the GenerateNewScramble() method I made? What references do I need at the top?

[acoustic belfry]

sorry for asking a lot...

But, if the script A has an int, and i want to have the same int in script B but with another value, what i should do?

how i can override that value?

[naive pawn]

Does all of this go in the GenerateNewScramble() method I made?
sure, that'd work
What references do I need at the top?
do you mean the class members here, or what exactly?
(at the top of the class, or where?)

[naive pawn]

not sure what you're asking. does B extend A?

[vocal wharf]

I assume I need to make a reference to the moves list at the top of the class?

[naive pawn]

if by "top of the class" you mean as a class member, then yes

[acoustic belfry]

my bad,

B is an inherited of A

[vocal wharf]

and the nextmove and randommove() things. What are those exactly? Sorry this is all so confusing to me

[acoustic belfry]

the thing is now i want to make a huge base for all my enemies, for make scripting my enemies more easier, or so i think

but before the rainbow i need the storm, to wich is where im right now, traslading my main enemy into the base
thats why im asking so much stuff

[naive pawn]

those are just placeholders, im only showing the general flow there, not full code

nextmove is a variable for storing the generated next move before commiting it into the moves list
randommove() is a method to get a random move

[vocal wharf]

oh I thought you were referencing something else my bad

[naive pawn]

is the int you're mentioning an inspector field, or what exactly? what are you trying to achieve?

[acoustic belfry]

yes an inspector field

just make that the base script float "speed" is zero, meanwhile in each enemy differs

[naive pawn]

just set it in the inspector?

you'd have a prefab for each enemy type, no?

[austere monolith]

https://hastebin.com/share/inubusetuy.csharp

could anyone tell me why the gravity aint workin?

[naive pawn]

why is gravity multiplied by speed?

anyways gravity is an acceleration, not a velocity

[austere monolith]

so it shouldnt be a vector3?

im using a char controller

[naive pawn]

that's not what i said, no

think about what each value you're using actually represents

x and z are magnitudes, then you multiply those by directions, then you add that with an acceleration
then you multiply that by speed, and then the time factor

move * speed is a velocity - a speed with a direction
that's what acceleration should be applied to

[austere monolith]

ok

kinda simple ig, i just didnt know what to do

[austere monolith]

thanks for trying to guide me in a direction instead of giving me the script

https://hastebin.com/share/epocuqazan.csharp

[naive pawn]

aren't you supposed to call Move exactly once per frame with a cc

[austere monolith]

[austere monolith]

if its by brackeys then hes right 😂

[naive pawn]

well docs don't say anything about it so

[austere monolith]

[supple flume]

you could probably have mauz be an array of ag if that's the main component you want to actually use

[supple flume]

i figured out the mistake lol

[naive pawn]

should probably name stuff better though

[supple flume]

they are arab words lol

[naive pawn]

"agagag" is a word?

[supple flume]

oh no

agagag isnt

but mauz is

[polar acorn]

Even then, agagagag is not a good name for a variable of type ag

[naive pawn]

yeah the "agagag" is the main one i was referring to

[polar acorn]

Yeah, mauz seems normal

[naive pawn]

though, types should generally be in PascalCase, so ag should be Ag

[naive pawn]

move * speed is the horizontal movement, velocity is the vertical movement, you can just add them together

make sure to add parentheses so the * Time.deltaTime happens last

[austere monolith]

ch.Move((move * speed + velocity) * Time.deltaTime);

yep gotit

[naive pawn]

alternatively, you could have speed multipled into move and then add velocity directly, or since it's only the gravity velocity, you could have that just be a float and add that multiplied by Vector3.down etcetc.. there's a lot of was to achieve this

thanks guysd

[vocal wharf]

I tried implementing some stuff but it's not letting me use that last part of the if statement 🤔

public void GenerateNewScramble()
{
    while (moves.Count < 20)
    {
        nextMove = possibleMoves[Random.Range(0, possibleMoves.Length)];
        if (moves.Count == 0 || nextMove != moves.Last)
        {

        }
    }


}

VS puts squiggly red lines under nextMove != moves.Last

[polar acorn]

And what does the error say

[vocal wharf]

it says "Operator '!=' cannot be applied to operands of type 'string' and 'method group'"

[polar acorn]

Because you can't compare a string to a function.

You probably want to run the function

https://learn.microsoft.com/en-us/dotnet/api/system.linq.enumerable.last?view=net-9.0
Last is a function, not a variable

[vocal wharf]

I need to take a break man this is confusing

[stoic summit]

anybody have any idea why this would be crashing roughly 25% of the time? my only idea is that raycasts might be really intensive computationally when you're doing them a couple hundred times at once, but I'm not sure on that.

[polar acorn]

What is this supposed to be doing?

Why are you taking one thing, casting it to itself, then making a list of one element to loop over?

Also this. Just use gameObject. You don't need this variable at all

[stoic summit]

a chunk of the map has a bunch of children under it where other map chunks can spawn, and I want a chunk to spawn at each one

[stoic summit]

neat, thanks

[polar acorn]

That's not what this does

[stoic summit]

it works though??

[polar acorn]

This literally just stores transform into a variable named spawn

[stoic summit]

it spawns a chunk at each one

[polar acorn]

Oh god damn it this is because of transform's weird gimmicky IEnumerable implementation isn't it

Okay, yeah, so Cast<Transform> on a transform magically turns it into a collection because of a terrible design decision Unity made 20 years ago.

[polar acorn]

You can still cut all the linq out and do foreach(Transform spawn in transform)

[stoic summit]

oh yeah, that would be way nicer lol

I code like a cro-magnon

[polar acorn]

Do any of the objects you are spawning themselves have this script on it

[stoic summit]

also how could I get rid of LastSpawned? I'm just setting it to the first chunk, then later it's updated to the last chunk spawned

[stoic summit]

naw

[polar acorn]

That was when I had thought the foreach loop would just contain one element in it. Since that chunk is running multiple times, it's actually useful, so you can just do Transform lastSpawned = transform

And then change it as you spawn things

[stoic summit]

hella, ty

[polar acorn]

As to why it crashes, it looks like it's because you only actually increment i if the raycast hits anything

If it doesn't, you spawn a bunch of things and then run the loop again without changing i

So if those things spawn in within view of the raycast, you'll go infinite

Actually, scratch that, reverse it. That's a !

[stoic summit]

yup was boutta say

[polar acorn]

So if they spawn in and they are in view of the raycast, they'll go infinite

[stoic summit]

that makes sense, easy fix at least lol

I appreciate the help bro

[vocal wharf]

@naive pawn do you think this looks ok? How can I display the moves with text? I could only think of scramble.text = moves but for some reason I get an error. Here is the whole code.

public class NewScramble : MonoBehaviour
{
    public TextMeshProUGUI scramble;
    private List<string> moves;
    private string[] possibleMoves = {"R", "L", "U", "D", "F", "B"};
    private string nextMove;
    
    void Start()
    {
        GenerateNewScramble();
    }

    public void GenerateNewScramble()
    {
        moves.Clear();
        while (moves.Count < 20)
        {
            nextMove = possibleMoves[Random.Range(0, possibleMoves.Length)];
            if (moves.Count == 0 || nextMove != moves.Last())
            {
                moves.Add(nextMove);
            }
        }
    }
}

scramble.text = moves; gives the error "Cannot implicitly convert type 'System.Collections.Generic.List<string>' to 'string'" which to me seems like it should be the same thing but I guess not

[eternal needle]

a List<string> is not a string. it is a list of them. you need to specify which string you want

[vocal wharf]

ah makes sense. I also tried moves.All but that gave an error too

[polar acorn]

A deck of cards is not a card.

Got any tips for what I can do?

[polar acorn]

Which one did you want to set scramble.text to?

[vocal wharf]

The string list called moves

[polar acorn]

You can't set a string to a list of strings.

Did you want to combine the list into a single string? Did you want to set it to one element in that list?

[vocal wharf]

I want to combine all of them and display that sequence on the text

So I got it all worked out but when I press play in Unity it gives the error "Object reference not set to an instance of an object" for all the lines having to do with the moves list. I have it referenced in the top of the class but it must have something to do with the fact that the list is empty at the start? I'm not sure. Any pointers on what's wrong here?

            {
                moves.Add(nextMove);
            }
        }
        scramble.text = string.Join(" ", moves);
    }
}

[polar acorn]

Where do you assign a value to moves

[vocal wharf]

it's empty until the GenerateNewScramble() method is called in the start function when moves are randomly selected from the possibleMoves array and added to the moves list

[polar acorn]

Where are you creating an empty list?

[vocal wharf]

I assumed that's what the reference at the top of the class does?

[polar acorn]

No, that creates a variable. Where do you assign a value to that variable?

[vocal wharf]

nowhere I suppose

[polar acorn]

That would be your issue

moves is null since you never create it

[vocal wharf]

how do I assign a value to it?

[polar acorn]

With =

[vocal wharf]

ah I see now

IT WORKS

you're a legend

[tawdry axle]

Hey everyone. I'm working on a 2D arcade beatem up game in unity and I'm having trouble with the enemy AI flipping 90 degrees in the X-axis whenever I hit play. Here's a video of it happening

I have the z-rotation constrained in the inspector and here's the code I have for the enemy rn

using UnityEngine;
using UnityEngine.AI;

public class Enemy1 : MonoBehaviour
{
    private NavMeshAgent agent;
    private Transform player;
    //public float walkSpeed = 3f;

    Rigidbody2D rb;

    private void Awake()
    {
        rb = GetComponent<Rigidbody2D>();
        agent = GetComponent<NavMeshAgent>();
        player = GameObject.FindGameObjectWithTag("Player").transform;
        

    }

    private void FixedUpdate()
    {
        agent.updateRotation = false;
        // Move towards the player using the NavMeshAgent
        if (agent != null && player != null)
        {
            agent.SetDestination(player.position);
        }
        //rb.linearVelocity = new Vector2(walkSpeed * Vector2.right.x, rb.linearVelocity.y);
    }
    // Start is called once before the first execution of Update after the MonoBehaviour is created
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        
    }
}

[rich adder]

where is rotation code or is it just rigidbody ?

oh its the navmesh agent

[tawdry axle]

@rich adder I'm using a navmesh agent and rigidbody component

[rich adder]

are you using a custom 2D navmesh ?

[tawdry axle]

Yeah it's a polyshape that I put the navmesh surface component on

[quick monolith]

I have a issue, I'm actually trying to make an enemy spawner, followed a tutorial about it.

Full code is here, I gave it bird prefab but looks like its not working is anyone has solution for it?

https://dotnetfiddle.net/Qgwpha

[rich adder]

seems weird to me because 2d collider and rigidbody 2d are locked on the same axis so its probably breaking it when the navmesh agent moves towards point, try removing them

[quick monolith]

I put it into main camera different positions

[rich adder]

define " its not working "

[quick monolith]

briefly yeah

[rich adder]

showing which part of tutorial you're at wouldn't hurt either

[quick monolith]

I can send the video gimme a sec

https://www.youtube.com/watch?v=cecD66fZ_4c&ab_channel=KetraGames

[tawdry axle]

@rich adderturning off the mesh collider doesnt do anything and turning off the nav mesh agent breaks the enemy movement entirely

[rich adder]

mesh collider ?

[tawdry axle]

I meant the capsule collider

[rich adder]

I said remove those completely

and test

[tawdry axle]

its not letting me remove the rigidbody for some reason but removing the 2d capsule collider just stops the enemy from being able to move the player

[rich adder]

did you right click the rigidbody 2d component and remove? are you getting an error wdym not letting you?

[tawdry axle]

Sorry I was able to remove the rigidbody but that didnt do anything/change the rotation

I can send a video

[rich adder]

yea its weird..can you screenshot the view so can see which way the navmesh surface from another view see where exactly that agent is going

[tawdry axle]

There is a bit of an offset

[rich adder]

thats why its not working... I thought you had more of a ZX plane going instead ur still using 2D renderer and YX ?

the orthographic view in scene view messed me up

[rich adder]

you could deal with the navmesh walking like this but keep the sprite facing the camera , you can rotate the graphics on child only but you still need a way to interact with the collider..

You could try this instead and keep things "flat" https://github.com/h8man/NavMeshPlus

[deep moss]

How do I code like snapping objects using empty child? Like robot arm has an empty child place next to a body and snaps when close. Something like transform and distance or something?

[alpine summit]

I'm not sure of the exact terms to describe what I'm looking for here so bear with me: Is there any way to give a script a list in the editor that I can fill by dragging in scripts with subclasses of a certain class? So that, in the main script, I can instantiate those subclasses for my game

more concrete context:

[slender nymph]

what is the Player type? is it a plain c# class or does it inherit monobehaviour? if it is the latter then it should JustWork™️ and you can drag prefabs that have a component that derives from Player into it. otherwise you wouldn't be "dragging in scripts", at best you could write a property drawer (or use an asset that does so) combined with SerializeReference to allow a dropdown list for the derived types, but it would be instances of that object stored in the array, not just a list of subclasses

[alpine summit]

it's just a c# class unfortunately

[tawdry axle]

I'm not sure exactly how to implement this. Is it like a plugin/package? Also I didn't realize I was doing the orientation incorrectly. Do you think it would be better if I tried to change the whole project to be on the YZ plane instead of XY? Also is there a simple way to do that>

[rich adder]

you missunderstood, you are using the XY plane as its default by Unity 2D . I thought you were using XZ which is more common in 3D plane as the "floor"
and yes the 2D navmesh is an extention from unitys built in navmesh but works better for 2D, its a separate addon You can read the instructions its easy to implement

[rich adder]

whats the usecase you're going for exactly ? snap can be done different ways

[deep moss]

i want it to snap on the face of a cube with another face of the cube. Like a socket kind of snap. Not in VR tho

Someone thought me a little but cant seem to remember the steps, something having to do with the parent having the script and the child as its position to snap

[rich adder]

I suppose you could use that with distance but might need to roll out something a bit more complex with rays / casts

[deep moss]

they use some kind of threshold too if im not mistaken

[rich adder]

thats always a given, you'd need to know when can you start snapping

tbh this a bit complex todo cause unity move .position from the origin point, you'd need to know the offsets and do quite a bit of math

[alpine summit]

the idea is that I subclass Player to define the different behaviors a player could have (e.g. local player, online player, AI player) so that I can swap them out easily. The reason I'm trying to expose this array in the editor is so that I can list the possible player types that are available. Which option do you recommend in that case?

[slender nymph]

read the two options I provided and choose which of the two best suits your needs

[near thicket]

Why is it that this triangle disappears during runtime when I change a value such as the vertex pos?
https://paste.mod.gg/kmqzrfumwxsh/0

I'm doing a basic rendermesh but it disappears whenever I change something, I have to stop and restart the player

[wintry quarry]

What did you change and how

Also your code is creating new arrays every frame instead of reusing one, which is pretty inefficient.

[near thicket]

yep I fixed it

[night minnow]

I'm trying to make a script that takes the location of your mouse cursor and moves a sprite over to that position. However the final result is way too large of a number and I need help with calculating it down so that it works within the game canvas.

[brave robin]

You're moving a rigidbody 2d, so guessing you want world and not canvas position

[night minnow]

I suppose? When referring to "Get Mouse Position" is that calculated based on the world space or canvas space?

[slender nymph]

#763499475641172029
but it's probably in screen space

[night minnow]

Sorry about that! I didn't realize there was a server just for visual scripting. Thank you!

[versed light]

i have this in my scriptable object:

[SerializeField]
GameObject _prefab;

I select my prefab from the list and it assigns but says "Type mismatch". Feel like i might be doing something dumb but i can't figure it out at this hour...

what does the error even mean in this context

[slender nymph]

are you assigning a field on a prefab? because you are selecting a scene object which prefabs cannot reference

[versed light]

what do you mean by assign a field on to a prefab ?

[slender nymph]

i mean is the object you are editing that is in the inspector a prefab

[versed light]

oh, its a field in a scriptable object not a gameobject

[slender nymph]

i do not mean the object being selected in the window because that is not a prefab, it is an instance of a prefab.

[slender nymph]

then it is an asset which cannot reference scene objects. you need to give it the actual prefab, not the instance in your scene

[versed light]

oh i thought the blue cube symbol meant it was the prefab version

[slender nymph]

you're selecting an object in the Scene tab which means you are selecting a scene object. the blue symbol just indicates that it is an instance of a prefab

[versed light]

oh i see now i had to hit the Assets tab

thanks ! 🙂

[alpine summit]

I chose a different option, which is to just create the list in the setup script :P

but thanks for the help

[slender nymph]

that's so much worse

[alpine summit]

worse than if Player were a MonoBehavior but if it works it works

[timid salmon]

Why is it every time i spawn a prefab om my bullet it says the size is negative

[sour fulcrum]

Is the size negative

[timid salmon]

Nope

nevermind it was omg srry🙏 😭

[split plover]

Sorry if thisis a stupid question, but what do voids do? Didn't find anything about it on the unity beginner scripting course so far

i looked it up and it says it stops things from returning a value, but if things dont return a value then how does code work in a void

[sour fulcrum]

so functions can return things, void returns nothing

so like

[split plover]

so im supposeed to put void on non functions?

[frosty hound]

For the record, they're not called "voids" , they're called functions.

[split plover]

wait i was supposed to be learning c++?

[frosty hound]

No

[split plover]

i've been learning c# 😭

oh

okay

[sour fulcrum]

when you use a printer it might be

Paper PrintPaper(Paper blankPage)
//stuff to fill paper
return (filledPaper)

but when you say, email someone, you don't get anything back from that action, hence void

[split plover]

no like im literally talking about the void, like in this

im not calling functions voids

[frosty hound]

Yes, you're talking about the Start function , which returns nothing (void)

[split plover]

i literally mean void

i think im confused

[frosty hound]

---

void AddNumber (int a, int b)

int AddNumber (int a, int b)

Both of these are functions.

The first will not send anything back from the function, hence void (ie, "nothing"). The second will send back an int via a return line.

[split plover]

should i keep watching the tutorials cause idk what private means in the code here

[frosty hound]

ignore it

[split plover]

ok

[frosty hound]

Edited for clarity, it means the same thing.

Stop spouting nonsense, you're offering nothing to this conversation.

[split plover]

So you put void on functions that you dont want to give code, does that mean if you put it in a earlier code block so that you can call the function in any code block connected instead of putting the function in every code block?

[sour fulcrum]

not give code, give value

[split plover]

well

[sour fulcrum]

the code in the function runs regardless of what it returns

[split plover]

yeah i guess thats what i mean

[split plover]

Yeah thats what i meant, it runs but it doesn't actually do anything

[frosty hound]

These have no relation to each other. You can call the function whenever you want, regardless of where it is in your code (physically speaking) or whether it returns something or not.

[split plover]

So how do i know when to put voids?

[frosty hound]

Whether you can access those functions to call, depends on scope. Which is to say, if it's a private or public function.

[sour fulcrum]

if your not returning something you use void

[frosty hound]

When you don't want that function to send something back to the line that called it.

Here's an example:

// Example of a function returning something back to the line that called it

void Start()
{
   int myAnswer = AddNumbers (2, 5);
   print ("My answer is: " + myAnswer);
}


int AddNumbers (int a, int b)
{
   int answer = a + b;
   return answer;
}

// Example of a function that does not return anything and handles all the code locally within itself (scope)

void Start()
{
   AddNumbers (2, 5);
}

void AddNumbers (int a, int b)
{
   int answer = a + b;
   print ("The answer is: " + answer);
}

[sour fulcrum]

(if you don't mind Osteel another example for the road)

public class Apple
{ }

public class TestClass
{
    void Start()
    {
        Apple myApple = GetNewApple();
    }

    //This functions's goal is get an apple, so it needs to return a value (an apple)
    Apple GetNewApple()
    {
        return (new Apple());
    }

    //This functions goal is to eat an apple, the goal doesn't neccesitate returning anything because thats not how eating works
    void EatApple(Apple apple)
    {
        //code to eat apple
    }        
}

[split plover]

Alright im gonna go look up what return is and then come back and see if I can understand this

Okay i think i get it now

[frosty hound]

Make a simple calculator game

[split plover]

so void stops it from returning to the main code (like start or eat apple) and return causes the code to go back?

[sour fulcrum]

ahh i see the confusion now

return isn't related to code flow

[split plover]

whats code flow

[sour fulcrum]

think about functions less logically and more like the things you do in life

[median hatch]

string ReturnAString(string hello)
{
Debug.Log(hello);
}

void Start()
{
string functionValue = ReturnAString("return something here);
}

[sour fulcrum]

standing up out of bed, you don't get anything back from that, you just do it

[median hatch]

probably not the best example

but you can call functions and set their return into a variable

[sour fulcrum]

finding your car keys, you do get something from that, the car keys, so you return carkeys so you can get that value after finding your carkeys

[split plover]

i'd be technical and say that you moved but ok

[sour fulcrum]

you moved but thats something you did

not something you got

[split plover]

Alright yeah no that makes much mmore sense

[sour fulcrum]

if i ask you to find my glasses you would get something back from doing that, the glasses

[split plover]

Well no because if i found your glasses i would have to give them back to you

[sour fulcrum]

yes

[median hatch]

actually that code is wrong wrote it on phone

[sour fulcrum]

so your function would be finding the glases, then maybe another to give them to me

but you need to get the glasses from the findglases function

so you return it

[median hatch]

int Number()
    {
        return 2;
    }

    int functionNumber = Number();

[sour fulcrum]

to bring it out of the function

[split plover]

so would there be a void on the second function or a return on losing themm

[sour fulcrum]

there might be a void on giving them to me yeah

[acoustic belfry]

Hi

I have a question, in theory InTriggerCollision is like a kind of update that only updates when theres something inside the trigger? Or not?

[median hatch]

just see a function as a random number machine, lets say you click on a button to activate the machine, the output will be a paper with a random number

[split plover]

Alright i'm honestly really suprised there wasn't a single youtube video explaining this cause this was super confusing before it was explained

[split plover]

its fine i understand it now

[median hatch]

sounds good

[frosty hound]

First of all, there is no InTriggerCollision. OnTriggerCollision updates when something enters the trigger. If you want to check if something is continually inside, you can use OnTriggerStay.

[acoustic belfry]

Got it

Thanks

[sour fulcrum]

I really like to use a Printer as a example of functions because you put paper in it, the work gets done in the machine (function) and the result comes out of the machine (function)

[split plover]

Are there more unity courses than just the beginner scripting one

[median hatch]

this is a cool example because you can then return apples that could have different colors or sizes or whatever

[sour fulcrum]

anything can happen in the apple machine 😄

[median hatch]

xD

[median hatch]

i'd say to work on something simple

you'll learn way more than any tutorial

[split plover]

I'll try to just continue working on what i was planning to make originally

though idk how ill get multiplayer to work i'll probably just watch a tutorial

[median hatch]

multiplayer?

[sour fulcrum]

i wouldn't do multiplayer

[median hatch]

youre crazy cat boi

[split plover]

its just so i could play it with my friends

[median hatch]

i wouldnt recommend it as your first expierence

[split plover]

its not gonna be any insane stuff infact i'll probably just use lan

[median hatch]

it adds a new layer to everything

and its a thick layer

[sour fulcrum]

even then i would recommend doing a little solo thing first

[split plover]

Well i'm mostly planning to make multiplayer games only in the first place so while i probably wont make multiplayer immediately it will probably be added anyways

[median hatch]

just saying because single player games are already crazy enough

[split plover]

I'll try

[median hatch]

its okay if your goal is multiplayer games

but i'd learn unity at least intermediate level first

[split plover]

I dont even think i've learnt unity at a beginner level 👍

[median hatch]

try to make a small project first

with everything

[split plover]

Would this just be having a super basic game

[median hatch]

sounds, game juice and one or two features

[split plover]

not super basic but like

[median hatch]

i promise you'll be way more confident tackling multiplayer after

[split plover]

I think the fact i want to do multiplayer first makes me confident enough but i definitely lack the skill

[median hatch]

so you know my first game was multiplayer

[split plover]

well now i do

[median hatch]

gave up when i realized i couldnt sync things dropping on the floor

but if you wanna give it a try

[split plover]

Its fine if stuff is a little delayed, my original idea was rblx but i do not wanna do that after i saw how absolutely abysmal the delay is there

[median hatch]

do you know stuff like client side and server side concerns?

[split plover]

yeah

[median hatch]

TCP or UDP protocols?

[split plover]

dunno what those are

if they're security stuff i dont need to worry i atleast hope none of mmy friends would try to hack eachother

[median hatch]

its not

if its just between your friends security isnt a problem

just use peer to peer connection or sth

[sour fulcrum]

They wanna do lan stuff it’s fine

[median hatch]

yea no worries then

give it a shot

[split plover]

Now that i think about this, this is a HORRIBLE idea, my internet is complete shit

it'll probably work anyways

[median hatch]

it should still work

[split plover]

but yeah i'll listen to your idea though, i'm going to make a basic singleplayer game first

[median hatch]

and if you wanna in the future you can add a co op feature to that basic singleplayer

brotato did that

[split plover]

Alright im gonna write this down so i dont forget cause its 8 am and i started trying to learn how to code like 9-10 hours ago so i am really sleeping

[split plover]

i am really sleepy*

[oblique gale]

public class EagleDetector : MonoBehaviour
{
    [SerializeField] private EagleScript _eagleScript; // Reference to the eagle script to notify

    private void OnTriggerEnter(Collider other)
    {
        Debug.Log(other.name);
        if (other.CompareTag(_eagleScript.playerTag))
        {
            Debug.Log("Player in range");
            _eagleScript.OnPlayerDetected(other.gameObject);
        }
    }

    private void OnTriggerExit(Collider other)
    {
        if (other.CompareTag(_eagleScript.playerTag))
        {
            Debug.Log("Player out of range");
            _eagleScript.OnPlayerLost(other.gameObject);
        }
    }
}

I don't understand how does OnTriggerEnter() only detects collider of a charactercontroller and not other types of colliders as well?

[polar acorn]

In the cases where the function doesn't run, do either of the objects involved have a Rigidbody

[oblique gale]

both have charactercontroller, does it need either charactercontroller or a rigidbody to be detected by a collider?

[keen dew]

You asked about a case when there isn't a CC. What components do the objects have when it doesn't work?

[polar dust]

in order for a collider to "see" that an object has collided with it, that other object needs to be a rigidbody

[oblique gale]

OOOOH so that's why

[acoustic belfry]

Hi, how i can put an animation clip inside a function wich is referenced? i mean the thing inside the ()

[oblique gale]

wait, can an object have both rigidbody and charactercontroller at the same time??

[shut swallow]

is there a way of seeing the boxcast box visually? For some reason my Boxcast isn't returning anything: if (Physics.BoxCast( center: castCenter, halfExtents: vector3HalfExtents, direction: slashDirection, hitInfo: out _meleeHitRegister, orientation: Quaternion.identity, maxDistance: 1.25f, layerMask: attackLayer )) { Debug.Log("Hit confirmed"); if (_meleeHitRegister.transform.TryGetComponent<StandardEnemy>(out StandardEnemy T)) { T.TakeDamage(attackDamage); Debug.Log("Enemy hit confirmed"); } }

context: ``` var updirection = motor.CharacterUp;
var slashDirection = castCenter - cameraTarget.position;
var slashDirectionQuaternion = Quaternion.LookRotation(slashDirection, updirection);

[eager elm]

You could draw each of the edges with Debug.DrawLine() or you could use a BoxCollider for your casting by calling boxCollider.Cast();

[shut swallow]

would just using a boxCollider better in this instance?

[eager elm]

probably, ye

[shut swallow]

I've check the sizes before, and they seem to be good

only problem that I have is I don't know how to check collision layers

I want to exlcude all except one

[sour fulcrum]

are you not checking it via attackLayer?

[eager elm]

LayerMask is somewhat tricky to set up, are you getting any hits if you remove it?

[clever oar]

hello, i have very basic question. When the variable with Quaternion data type is defined, what is its default value after definition? null?

[shut swallow]

wait lemme try this

[shut swallow]

do I just set the collision object in attackLayer?

[sour fulcrum]

What do you mean by that

[shut swallow]

Layer -> attackLayer

[sour fulcrum]

thats how layers work yeah

[shut swallow]

ah ok

[sour fulcrum]

for most things in Unity that layer is used for both rendering and physics which is a little stupid and dumb and nowadays some things seperate it but

thats the goto

[shut swallow]

                    (
                        meleeHitCollider,
                        position: castCenter,
                        rotation: slashDirectionQuaternion,
                        parent: root
                    );```So I've instantiated a box collider, how do I ask it to return hit data?

I've read the OnCollisionEnter API and didn't even understand a speck of it

[eager elm]

you should just have it as a reference and attach it to your gameObject instead of Instantiating it, then before casting make sure the position and rotation is set correctly and use boxCollider.Cast() for getting the data.

[hexed terrace]

Unity 6 has rendering layers too

Layers is the "normal" layers that have been in forever, just too large to fit expanded

[sour fulcrum]

yee i know nowadays they are trying to split it up

[hexed terrace]

appologies, I totally missed the end of your msg

[shut swallow]

that would be fine if not for cases like this

I have multiple melee hits that are detached from the player

I can't parent a hitbox and call it a day

[eager elm]

can you add the boxCollider to the projectile / melee hit itself?

[shut swallow]

the projectile is also an instance, so no(?)

                    (
                    vfx_slash,
                    position: castCenter,
                    rotation: slashDirectionQuaternion,

                    );
                Destroy(slashvfxinstance.gameObject, 1);```

At least, I'm not aware of any method that will work

[charred spoke]

What do you mean you can just add a collider to your prefab

[shut swallow]

I have no idea how to do that lmfao

[eager elm]

Is vfx_slash a gameObject? You should be able to add it to it, or even better make a new class called "Projectile" or something that holds both a reference to the VisualEffect and the collider.

after all, it should be the slash itself that handles the hit detection, not the player.

[charred spoke]

Just use the add component menu. Then you will also need a script on the gameObject that handles collisions

[shut swallow]

it's a prefab of a Visual Effect

[charred spoke]

If you do not know how to do this stuff I suggest you !learn

[naive pawn]

so you can add colliders to that

[eternal falcon]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[naive pawn]

there literally is an AddComponent method
but also, you have a prefab that you're cloning. you can just add it there

[shut swallow]

Something like this?``` BoxCollider meleeHitColliderInstance = Instantiate
(
meleeHitCollider,
position: castCenter,
rotation: slashDirectionQuaternion,
parent: root
);

            VisualEffect slashvfxinstance = Instantiate
                (
                vfx_slash,
                position: castCenter,
                rotation: slashDirectionQuaternion,
                parent: root

                );```

[naive pawn]

no, not at all

you've already added the collider to the prefab, no? you're instantiating the prefab twice here

Instantiate with a component clones the entire gameobject the component is attached to

[shut swallow]

so even if I instantiate VisualEffect slashvfxinstance it has a collider?

[naive pawn]

yes

[polar acorn]

Just open up the prefab you're already using and add a collider to it

[shut swallow]

yea I did that

[polar acorn]

Then the thing you instantiate will also have a collider

[shut swallow]

does collider normally eject overlapping objects on collision?

[polar acorn]

If it's solid that's what it's supposed to do

[naive pawn]

if neither are set to trigger and they interact, yes

you can just make it a trigger though

[shut swallow]

{
    [SerializeField] private int attackDamage = 1;

    private void OnCollisionEnter(Collision collision)
    {
        Debug.Log("Slash hit!");
        // register hit
        if (collision.collider.TryGetComponent<StandardEnemy>(out StandardEnemy T))
        {
            T.TakeDamage(attackDamage);
            Debug.Log("Enemy hit!");
        }
        Destroy(gameObject);
    }

}``` had this script attached to my prefab, doesn't seem to work

The Three Commandments of OnCollisionEnter:

1. Thou Shalt have a 3D Collider on each object
2. Thou Shalt not tick isTrigger on either of them
3. Thou Shalt have a 3D Rigidbody on at least one of them

[shut swallow]

but it has to be a trigger for it to not be pushing the player tho...

ohh

either

[naive pawn]

yeah, so use OnTriggerEnter instead

[shut swallow]

nvm

yea

[split plover]

[shut swallow]

use the `

[polar acorn]

Then you probably don't want to use the function that specifically requires it to not be a trigger

[shut swallow]

three before, three after your block of code

if anything large, use a code dump like !code

sorry am a idiot lmfao

using UnityEngine;

public class MovementStateManager : MonoBehaviour
{
    public float movementspeed = 3f;
    [HideInInspector] public Vector3 dir;
    float hzInput, vInput;
    CharacterController controller;
    void Start()
    {
        controller = GetComponent<CharacterController>();
    }
    void Update()
    {
        GetDirectionAndMove();
    }
    void GetDirectionAndMove() {
        hzInput = Input.GetAxis("Horizontal");
        vInput = Input.GetAxis("Vertical");

        dir = transform.forward * vInput + transform.right * hzInput;

        controller.Move(dir * movementspeed * Time.deltaTime);
    }
}

I know this is probably stupid but can someone tell me why this is working 😭
followed a tutorial but i have zero idea why it works because none of the movement keys that are moving the character are even in the code. I thought i would just be able to type it out and look at the code to figure it out but i really have no clue
