[heady iris]

so you can just do "foo\nbar"

[heady iris]

You need to mark all of these classes as [System.Serializable]

Not just CharacterDataArray

[willow hull]

oh dam ya right, thank you very much

[worthy willow]

That does work with normal text, but I have a ToString() function that is being used. How can I implement "\n" with the function?

[leaden ice]

\n not /n

[simple egret]

Backslash

[worthy willow]

oh

[simple egret]

You wrote it correctly in Discord. When it's done right, the two characters will become yellow in the string

[leaden ice]

anyway you should do something more like:

PointsGained.text = $"{PlayerPointAdd}\nSurvivors Bonus {browniepoints}";```

[rocky jackal]

@heady iris could you maybe help me figure out why i dont get diagonal edges for the directions like img1 but instead i get edges like img2 where the edges between my flows are straight ? that image is a bit older and has a few mistakes in it but ive fixed them it currently looks more like img3 but thats just really bad to read

https://gdl.space/zigejuhoto.cs

[leaden ice]

You are only considering cardinal directions as neighbors in your code

            neighbors.Add(current + new Vector2(0, 1));
            neighbors.Add(current + new Vector2(1, 0));
            neighbors.Add(current + new Vector2(0, -1));
            neighbors.Add(current + new Vector2(-1, 0));```

No diagonals

Add diagonals here if you want to consider diagonals

[rocky jackal]

but thats how they did it right here and they got diagonal edge flow https://www.redblobgames.com/pathfinding/a-star/introduction.html

[leaden ice]

Where do you see diagonals?

I see zigzag steps

[rocky jackal]

thats what i meant

i dont get any zigzag steps

[leaden ice]

you have zigzags

what do you think the left, down, left, down etc arrows are

[rocky jackal]

that are zog zags but i dont have zig zags i have this

[leaden ice]

I don't know what that's a picture of

[rocky jackal]

i dont have arrows i have colors so i can see what im doing

[leaden ice]

I don't understand your colors

or what they mean

or what I'm looking at

Also note that when dealing with manhattan distance, a zigzag is just a fast/slow as an "L" shaped path

[rocky jackal]

each collor corresponds to a direction

[leaden ice]

the zigzag would happen only with an as-the-crow-flies heuristic function

[rocky jackal]

but i dont want a 90° angle in my roads

[rocky jackal]

i cant find anything about a "as-the-crow-flies" function

[leaden ice]

Where's your heuristic function?

[leaden ice]

it's just the regular distance function

https://docs.unity3d.com/ScriptReference/Vector2Int.Distance.html

[rocky jackal]

i dont use that

[leaden ice]

Then don't complain that you don't get nice results

A* requires a heuristic to function nicely

[rocky jackal]

im using Breadth First Search and thats supposed to give zig zags too according to this page https://www.redblobgames.com/pathfinding/a-star/introduction.html

[rocky jackal]

im not using a*

[leaden ice]

BFS isn't going to prefer a zigzag to straight lines

it will give equal weight to both

and since you're always checking "up" before "right" or left or whatever, it's going to just pick the first one that works

[leaden ice]

You can see in the red blob games source code they did a little hack to get the "stairstepping" behavior. It doesn't come naturally

without this hack you will get straight lines not a zigzag

(yes I looked at the web page source to find this)

[rocky jackal]

omg, thank you. how do i recreate this ? what do they mean with flip every other tiles edge ?

[neon nymph]

Finally created gravity and jumping and learned Raystack

The Code:

using System.Collections.Generic;
using UnityEditor.Rendering;
using UnityEngine;
using static UnityEngine.Rendering.DebugUI.Table;
public class NewBehaviourScript : MonoBehaviour
{
    public CharacterController controller;
    public float gravity = -9.81f; // Gravity value, adjust as needed
    public float jumpHeight = 3f; // Jump height, adjust as needed
    public float speed = 12f; // Movement speed, adjust as needed

    private Vector3 velocity;
    public bool isGrounded;
    public float isGroundedCheckDistance;
    private float isGroundedExtraCheckDistance = 0.1f;
    public CapsuleCollider CapsuleCollider;
    void FixedUpdate()
    {
        float x = Input.GetAxis("Horizontal");
        float z = Input.GetAxis("Vertical");
        float jumpInput = Input.GetAxis("Jump");
        isGroundedCheckDistance = CapsuleCollider.height / 2 + isGroundedExtraCheckDistance;
        RaycastHit Hit;
        if (Physics.Raycast(transform.position, -Vector3.up, out Hit, isGroundedCheckDistance))
        { //if the ray hit
            if (Hit.collider.gameObject.tag == "Ground")
            {
                isGrounded = true;
            }
            else
            {
                isGrounded = false;
            }
        }
        else
        { //if the ray didn't hit
            isGrounded = false;
        }
        // Check if the player is grounded

        // Movement
        Vector3 move = transform.right * x + transform.forward * z;
        controller.Move(move * speed * Time.deltaTime);
        // Apply gravity
        if (isGrounded && velocity.y < 0)
        {
            velocity.y = 0f;
        }
        velocity.y += gravity * Time.deltaTime;
        controller.Move(velocity * Time.deltaTime);

        // Jumping
        if (isGrounded && jumpInput > 0)
        {
            velocity.y = Mathf.Sqrt(jumpHeight * -2f * gravity);
        }
    }
}```

[leaden ice]

The simplest equivalent for you would be like:

            neighbors.Add(current + new Vector2(0, 1));
            neighbors.Add(current + new Vector2(1, 0));
            neighbors.Add(current + new Vector2(0, -1));
            neighbors.Add(current + new Vector2(-1, 0));
            if ((current.x + current.y) % 2 == 0) neighbors.Reverse();``` @rocky jackal

[rocky jackal]

so it basically just switches arorund the direction in wich it checks for neighbours ?

[leaden ice]

Yes, for every other tile

even tiles search their neighbors in reverse order

[neon nymph]

The result:

[cobalt gyro]

anyone know any good resources on how to accomodate for the differences between phone screens

[weary swift]

Yo ! Let's say I want to know if two floats are approximately equals, but with a threshold of three digits after the comma. Can you give me the function or at least ideas on how to do that effectively. Examples : Approximately(123.123456f, 123.123856f) == true
Approximately(123.122456f, 123.123856f) == false

I tried this but i'm not sure if it the best way. (or even if it is accurate)
return Mathf.Abs(b - a) <= 0.001f;

[cobalt gyro]

multipy by 3, round both numbers then divide them by 3

[weary swift]

Can you explain to me how this works please ?

[leaden ice]

bool same = Mathf.Abs(a - b) < 0.001f; note that floating point numbers are represented in binary, not decimal, so this is going to be subject to floating point precision error

[cobalt gyro]

not by three, 100

[leaden ice]

GigaElmo is suggesting rounding the numbers to the nearest 1/1000th, then comparing

Which means though that 1.0001 and 1.0009 will not be considered the same

even though they're the same to three digits

[weary swift]

So if I understand.
123.123456f * 1000 -> 123123.456f
123.123856f * 1000 -> 123123.856f
Rounded :
123123.456f -> 123123f
123123.856f -> 123123f
This means they are "equals" right ?

[cobalt gyro]

guess that works too

[weary swift]

Why ?

[weary swift]

That wasn't what you said ?

[cobalt gyro]

bool Approximate(float a, float b)
{
    float _a = a * 100;
    float _b = b * 100;

    _a = Mathf.Round(_a);
    _b = Mathf.Round(_b);

    _a /= 100;
    _b /= 100;
    
    return _a == _b;
}```

[leaden ice]

1.0001 will round to 1.000, 1.0009 will round to 1.001

[weary swift]

Ah ok

[cobalt gyro]

i was thinking something more like shown above but i guess your solution works too

[leaden ice]

but they are 0.0008 apart

which is less than 1/1000th apart

So i don't like the rounding solution

distance solution seems better IMO

[weary swift]

What is distance solution ? The GigaElmo proposition ?

[leaden ice]

the original Mathf.Abs(b - a) <= 0.001f;

[weary swift]

Oh no, he is using round so I guess not

[weary swift]

But if I round the numbers up then it will work right ?

1.1 -> 2, 1.8 -> 2

[leaden ice]

It really depends what you're after

[weary swift]

more like 1.1234 -> 1.124 and 1.1238 -> 1.124

[leaden ice]

that would be using the Ceil function

[cobalt gyro]

then just use Mathf.Floor(float a)

[weary swift]

I guess ceil is the exact opposite right ?

[cobalt gyro]

yes

[leaden ice]

again it depends what you're after. Are you looking for:

These numbers are less than 1/1000th apart
Or are you lokoing for:
These numbers are in the same 1/1000th sized bucket

[weary swift]

Just comparing two values that are the same at least until third digits

[leaden ice]

If it's the former - use distance.
The latter, use Ceil or Floor

[cobalt gyro]

 bool Approximate(float a, float b, int decimalPlaces)
 {
     float _a = a * Mathf.Pow(10, decimalPlaces);
     float _b = b * Mathf.Pow(10, decimalPlaces);

     _a = Mathf.Floor(_a);
     _b = Mathf.Floor(_b);

     _a /= Mathf.Pow(10, -decimalPlaces);
     _b /= Mathf.Pow(10, -decimalPlaces);
     
     return _a == _b;
 }```

[weary swift]

What I want is to say 123.123 == 123.124

[leaden ice]

well those are only the same to 2 decimals

not 3

[weary swift]

(I changed from one less digit)

[leaden ice]

just do the rounding solution but replace Round with Floor

[weary swift]

Yes I changed, but it's the same idea

[weary swift]

Perfect ! Thanks you very much !

Just to understand, the distance solution was to know if the two numbers are close to 1/1000th and my solution is to know if the numbers are less than 1/1000th right ?

[leaden ice]

no

[weary swift]

Should I forget what you just said x) ?

[leaden ice]

it's the difference between measuring the distance between the numbers and checking which bucket the numbers are in

[cobalt gyro]

also use *= not /= in the example i showed

[leaden ice]

two numbers in the same bucket will always be less than that distance apart, but two numbers that are less than the distance apart may be in different buckets

for example 1.212 and 1.209 are less than .01 apart

but they are in different buckets

[weary swift]

I'm not gonna copy your answer I'm gonna adapt it for my needs but thanks !

[weary swift]

I guess that's the term "bucket" that I don't understand. Bucket in this case means what ?

[leaden ice]

all the numbers between 1.00 and 1.0999999999 repeating

[weary swift]

1.21 and 1.23 same bucket
1.21 and 1.11 not the same bucket

[leaden ice]

is one bucket

then [1.01, 1.02) is the next bucket

then [1.02, 1.03) is the next bucket

make sense?

[weary swift]

Yes, thanks !

Thanks for all the help !

[heady iris]

the important thing is that two numbers can be extremely close, but go into two different buckets

This has some important implications

If A and B are in the same bucket, and B and C are in the same bucket, then A and C are in the same bucket

[weary swift]

Like 1.0999999 and 1.1

[leaden ice]

exactly

[heady iris]

This isn't the case if you go by distance

[weary swift]

Yes I understand then, thanks !

[heady iris]

If A and B are similar, and B and C are similar, A and C might not be similar

[weary swift]

A = 1.19, B = 1.2 and C = 1.29 ?

A and B same bucket, B and C same, but A and C no ?

[leaden ice]

assuming your buckets are 0.01 in size, A and B are in different buckets, and C is in the same bucket as B

[weary swift]

Oh ok, I get it

Yeah I'm sure I get it, thanks !

[weary sapphire]

Ok, I'm still stumped. What is the W value in a quaternion?

[leaden ice]

If you're asking that, it means you think you know what xyz are and you don't

[weary sapphire]

Do you realise how unhelpful that is?

[leaden ice]

It's somewhat helpful

because it should make you realize you know less about them than you thought

if you thought xyz were angles around those axes or something

[weary sapphire]

All its helped with is making me feel somewhat stupid mate, thanks

[leaden ice]

You're welcome. If you want to really know how the math works, watch this https://www.youtube.com/watch?v=zjMuIxRvygQ

but I can tell you it's completely unecessary

you do NOT need to know how the math behind Quaternions work to use them in Unity

I don't know (I knew once, but the knowledge is useless so it is gone), but I use quaternions all the time. All you need to know is that they are variables that represent a rotation from the identity, to familiarize yourself with the API https://docs.unity3d.com/ScriptReference/Quaternion.html and that * can be used to compose them

[weary sapphire]

If you've just turned around and said that you don't know yourself, don't judge me for not knowing mate.

[weary swift]

🦁

[heady iris]

the point is that you do not need to grok how quaternion math works to use Unity's Quaternion class

Quaternions are an extension of the complex numbers, much like how complex numbers are an extension of the reals

A quaternion is made up of four real numbers, and has the form a + bi + cj + dk

or, using Unity's names, x + yi + zj + wk

XYZ are the common names for the first three numbers in a vector

W is used for the fourth because you run out of letters

hence XYZW

Without a decent understanding of how the quaternion group works, you cannot do anything meaningful with the quaternion's four values

I do not have a decent understanding of the quaternion group.

[latent latch]

yeah, you can treat W like a buffer because you need more room to work with

[heady iris]

you also see four-vectors in shaders

any time you're using homogeneous coordinates

[latent latch]

similar to how you want to rotate on the z axis in 2D, but in 2D you've only got two axis so that's one way to think of it

[latent latch]

pretty cool video, ill probably watch it when I get home

[heady iris]

Unity really should've just called it Rotation

and given it a method called ExposeQuaternion or something

it's way too easy to think that rotation.x is the euler X angle

[latent latch]

Just stick to Quaternion.AngleAxis, rotate around world axis, and stick to xyz ordering (z into y into x)

never worry about gimbal again

[hard viper]

let’s say I have a ruletile on a tilemap. I now want to set that exact same sprite onto a different tilemap (without refreshing, so it does not check again what its neighbors are). Is there a way to do that?

(does my question make sense?)

[dusk apex]

You want to change the tile map without allowing it to update?

ie dirty etc but not relative to visuals

[hard viper]

kind of. Tilemap A has ruletile B that (based on the rules), shows sprite C. I have tilemap D, and I want to put sprite C onto it.

Because ruletile B has special logic to check specifically tilemap A (and other specific tilemaps), so if it tries to refresh, it will be wrong when it is on map D

i need to not even refresh. Just make a copy of what it currently looks like, and don’t change it

[dusk apex]

Sounds hacky

[heady iris]

a snapshot, essentially

[hard viper]

yes

I am trying to make a copy-paste with drag for my game

[austere bolt]

ArgumentNullException: Value cannot be null.
Parameter name: path2 anyone know why?

[heady iris]

well, saveFileName is probably null

have you checked the values of it and saveDataDirectoryPath?

[hard viper]

where you select a region on a tilemap, select some stuff, it gets copied to a preview tilemap, which is on an object that gets dragged around

[dusk apex]

Make it not null or determine why it thinks it's null?

[austere bolt]

i set savefilename to character still had the same issue

[heady iris]

prove that both of those variables are non-null by logging them

[hard viper]

use debugger and set breakpoint to see the contents

just see wtf those variables are set to

[heady iris]

It looks like you can ask which sprite is on a tilemap at a certain position.

https://docs.unity3d.com/ScriptReference/Tilemaps.Tilemap.GetSprite.html

[hard viper]

ok. now I need to be able to set a sprite

so that is half the puzzle

[heady iris]

you'll need a tile for each sprite, I guess

[hard viper]

that is a fuckload of tiles

can I maybe instance it during runtime?

man, am I going to need to make 2,000 asset files for just this little feature?

[heady iris]

a tile is just a scriptable object

I bet you can just create instances at runtime and hold them in a Dictionary<Sprite, Tile>

[hard viper]

that is what I am thinking, but that seems even more hacky

if I instance an SO in editor play mode, does it permanently keep the file?

[heady iris]

No.

There is no asset.

[hard viper]

thank god

[heady iris]

You'd have to explicitly create an asset

https://docs.unity3d.com/ScriptReference/ScriptableObject.CreateInstance.html

[hard viper]

so I just need to do new Tile(…)?

[heady iris]

no, use CreateInstance

that was misleading; CreateInstance has nothing to do with actually creating the asset (:

[hard viper]

the fuck

but this won’t make a new file?

[heady iris]

Correct.

It creates a new instance of the scriptable object type

var set = CreateInstance<IconSet>();
AssetDatabase.CreateAsset(set, BASE_PATH + "/" + setName + "/" + key + ".asset");

the second line actually creates an asset

[hard viper]

ok, i got you

does this mean I can make Non-SO asset files to make instances as files?

[heady iris]

I don't know what you mean by "non-SO asset files"

[dense estuary]

Is there a version of Vector3.Angle that produces a value between 0 and 360 instead of 0 to 180?

[heady iris]

there's Vector3.SignedAngle

it gives you an angle between -180 and 180

it takes an extra argument to define the axis of rotation

[hard viper]

w/e, doesn’t really matter.

[heady iris]

https://docs.unity3d.com/ScriptReference/Vector3.SignedAngle.html

see the description

[hard viper]

So this would be good?

[wary coyote]

design pattern question

My game is networked multiplayer. Sometimes I need to figuratively slap everyone's hands away from their controls and take total control of the program to make fixes or do whatever. I need a way to shut down all interactivity from the clients, without disconnecting them, as well as I need to potentially interrupt anything they might be doing at the time, and do all of this without fucking up anything or causing null references or making orphaned instantiated objects or any other problem.

Lets call this concept the GM Override.

I am not sure how to achieve this since it sounds like having every single function in the program constantly checking 'If total override != true' which won't be feasible, and would further need even more code to allow the figurative super user to take control and not get stopped themselves by the lockdown they initiated.

How do I correctly put this design to code? Whats a better design? Is this even what I want to do?

I am not worried about the actual fixes and changes being performed, I am only worried about how do I cleanly turn off everyone's hands without turning my own hands off, and passing around / referencing this override state without it becoming a bloated mess nightmare of checks on override state

[dapper schooner]

Anyone have an IAP for WebGL they would recommend? '

[latent latch]

Well, apply it to how ownership is being checked, and apply additional comparison logic to that. Even if they are the owner, if input isn't being accepted, then deny that request. Interrupting something already issued by the server would have to be handled independently like a pathfinding module though.

I'd probably go with an observer pattern then if there are similar type modules where you do need to halt a player's action.

[wary coyote]

Alright Ill look into that approach

[latent latch]

Im thinking of terms like a MMORPG where there is some escape method to every action, so ideally you'd have some IInterupt that implements and handles how a module is halted.

[silver lava]

yo do you guys think it would be possible to take a screenshot of what the player is looking at when a certain key is released then apply that screenshot as a texture on to a wall?

im trying to attempt to recreate catacombs of solaris and i think that would be a decent starting point

[cosmic rain]

Yes. Render the camera view to a render texture and use it on whatever you want.

[silver lava]

Do you think I'm going along the right tracks for something like this?

[cosmic rain]

Probably. Never heard of that game.

[silver lava]

Alright, it's an odd one

[barren flicker]

Hello, I am generating a noise grid with compute shaders for later applying marching cubes over it. I have an algorithm for modifying the noise so it generates caves and a crust (im generating spherical worlds). I've divided the shader in 3 parts:
if the position is smaller than cave radius, generate cave
else if the position is smaller than the inside of the crust, generate inside crust
else if the position is smaller than the outside crust, generate outside crust

If i run with one of the if statements commented, it generates everything perfectly, but the second i uncomment it, it generates very weird things

It doesnt matter what "if" I comment, that it runs fine

[mental rover]

you may want to share your code & be a bit more specific about what "generates very weird things" means

[barren flicker]

okay, give me a sec

This is what normal would look like, with the 2 first "if"s working and the 3rd one responsible for the outer side of the crust commented

this is with the inside crust and the outside crust only (also "normal")

And this is "weird": triangles disappear

The only thing that has changed through the 3 executions is the noise generating file

[mental rover]

it's not really clear to me what's happening here - I'd guess when doing every layer there's a non-smooth boundary being generated in the noise map that the marching cubes implementation is failing on

[lean sail]

I have effects in my game which are like "When X happens, do Y" made using scriptable objects. I realize I want to delay some effects because of cases like "When taking damage, reflect damage back to the attacker". If both characters have this effect, itll cause an infinite chain but at least with a delay it wont freeze the game. I was thinking the following:
All characters in my game have a Character script, I could run a coroutine on there but i worry about edge cases like a character being destroyed and the coroutine stopping. Or anything else i am unaware about
I could create a new gameobject which has a script I run the coroutine on, which sounds like a little more work but could be worth it.
Any thoughts on what I should do?

[calm talon]

how do I change the vertices of a sprite shape via code? I am trying to align the vertices/control points of a sprite shape to the vertices of a composite collider 2D

[fiery gate]

how do i get my intellisense working

[soft shard]

Maybe you could setup a "effects manager" (could be a service or a monobehaviour that starts with your scene or something similar), you could run the coroutine on that or use something like a Task to not have to rely on the life cycle of that mono behaviour, though in a case like that where you can have a back-and-forth reaction, I would maybe put in some kind of stoppage, like "isAffected" that can only be triggered once, or if you actually want the back and forth as part of your games design, maybe limit it to something like 5 times, and use a counter to keep track of how many times its been applied to that character or you could treat it like a "spell" system where it can "stack" up to a certain number of times before just capping, like MMO's do when the same ability is applied on the same target more than x times

[latent latch]

My system prevents exponential effects from happening such that only primary abilities can apply secondary abilities.

[lean sail]

yea i plan on not having damage reflect if it was reflected damage the character was hit by, but there are likely other cases I will run into like "heal extra hp when healed". I am more so just trying to prevent myself from running into an infinite unstoppable chain that will require me to close my unity.
I do have a singleton object pool, which manages a dictionary of pools. i could use it to spawn objects but im unsure if im even gonna stay with a singular pool manager like this. Its scary to think about how Ill need to ensure each prefab is registered and how Ill handle transferring them between scenes. I think ill just try it anyways for now

[latent latch]

Could do like a flag for these effects such that they are reactive, and reactive effects can't trigger other reactive effects

[lean sail]

Ill end up doing something to fix that overall, but thinking about it ill need delays anyways. Spawning objects will help me have models as well with it i guess

thanks for the inputs

[faint hornet]

Anyone have a solution to connect a ToggleGroup to a set of buttons ( next, previous) ?

I tried using a custom script extending the toggle group to make my own functions to find the currently selected toggle and then to select next/prev depending on button clicked. no luck.

[latent latch]

button clicked => if toggle true go next, else go previous

[faint hornet]

go next is not a function

[faint hornet]

i know how to connect the logic. im missing the logic

[latent latch]

https://docs.unity3d.com/2018.3/Documentation/ScriptReference/UI.ToggleGroup.html
"When using a group reference the group from a Toggle. Only one member of a group can be active at a time."

https://docs.unity3d.com/2018.3/Documentation/ScriptReference/UI.ToggleGroup.ActiveToggles.html
returns IEnumerable, so my solution would be when you click the button, get the active toggle and do your comparison from the active toggle and then do your logic

[oblique nexus]

I came up with the perfect null check.
What do you guys think?

using Unity.VisualScripting;

    public static bool IsNull<T>(T _var)
    {
        var v = _var;
        return v == null || v.ToSafeString() == "(Destroyed)";
    }

[quartz folio]

Truly awful to rely on a terrible extension method in a visual scripting package, and to constantly allocate strings and compare them to test for null

[tall salmon]

does someone have a link to a video explaining how lists work? it would be very usefull since i cant seem to find a good one

[cosmic rain]

Maybe have a look at the Microsoft C# manual.

[tall salmon]

the words there confuse me quite a bit

[rigid island]

https://www.c-sharpcorner.com/article/c-sharp-list/

[tall salmon]

its so technical for me

oh

navarone

hi!

[chilly surge]

What about lists that you want to understand? It's kind of a foundational building block and it really doesn't do all that much.

[tall salmon]

i want to know how to create them and use them in general

[cosmic rain]

Then research the confusing words. They are probably important to understand.

[chilly surge]

Eh I was about to post https://learn.microsoft.com/en-us/dotnet/csharp/tour-of-csharp/tutorials/arrays-and-collections but that uses collection expression which isn't available in Unity because of the C# version.

[tall salmon]

i want to make an enemy spawner that for example has 10 coins and can spawn certain amount of enemies depending on the price, for then putting the enemies on a list and spawning them

maybe im focusing it wrong and that isnt used for what im trying to do

[rigid island]

break down the problem into smaller more manageable ones

[tall salmon]

i somehow did a base for what i want to do as a whole

this is kinda all the steps involved into what i want to do (ignore that its in spanish)

and in selecting the amount of enemies i had the idea to do a list for it

maybe it doesnt make sense

[tall salmon]

navarone srry for the ping but in case you could help me it would be great

is there any efficient way to assign each number to one game object?

or do i need to write this for each number:
if (choosedSpawner == xnumber)
{
(some random code that makes it select x spawner)
}

[olive drift]

Could you tell me in detail?

[tall salmon]

sure

[mental rover]

use an array

[tall salmon]

lemme think how to explain it all in a compressed way

[tall salmon]

idk what that is

so i basically want to make a wave spawner that spawns random amounts of enemies at random positions

i have 4 selected positions

upper lower left right

and once choosed spawner selects a number i want to tell that the enemies should spawn in certain spawner

i could write a lot of ifs statements that would make it happen (or atleast so i think) but i wanted to see if there is a more efficient way of doing this

[olive drift]

What do you use if staements for?

[tall salmon]

i would make the if statement be
if( choosedSpawner == xnumber)
and then write a code that would use the transform position of the corresponding spawner asigned to that xnumber

idk if im explaining myself

in case im not tell me and ill try to figure out how to explain in it other way

[fervent furnace]

Use “xnumber” as index to access array element
And code beginner problem

[olive drift]

So do you mean when first wave?
if( choosedSpawner == 1)

[tall salmon]

what is index and array element?

[fervent furnace]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/arrays

[tall salmon]

ty!

[tall salmon]

i forgot to answer to this

i guess something like that

since its a kind of open answer it can point towards lot of situations

but yeah i think we mean the same

[cosmic rain]

Then write it as you can and share the code. We might be able to direct you to a proper way of refactoring it.

[tall salmon]

alright ill try, but idk how much time i will take for it

oh you are the slimeascend creator

i played your game 2 days ago i think

[cosmic rain]

We can wait. Take your time.

[tall salmon]

it was good!

[faint hornet]

can anyone tell me why this code isn't working? I used StartCoroutine correctly. becasue the rect transform moves after 2 seconds but it's instantaneous. the duration is set to 5 seconds. PLUS, its not even moving to the correct localPosition. it's like way off

I have used Coroutines so many times and i've never had this issue... Am i tired, or wtf.

IEnumerator Move(Vector3 start, Vector3 end)
  {
    yield return new WaitForSeconds(2);

    float elap = 0f;
    movable.localPosition = start;
    while (elap < 1f)
    {
      elap += Time.deltaTime / moveAnimation.duration;
      elap = Mathf.Clamp(elap, 0f, 1f);
      float eval = moveAnimation.animationCurve.Evaluate(elap);

      movable.localPosition = Vector3.LerpUnclamped(start, end, eval);
      if (elap >= 1f)
      {
        movable.localPosition = end;
        break;
      }
      yield return null;
    }
  }```

[cosmic rain]

Debug.🤷‍♂️

[faint hornet]

i think unity is totally bugged right now wtf... its not moving correctly but the positions still have an offset.. i didn't change any code. idk how to debug this. it makes no sence

[cosmic rain]

The way you debug is always the same: debug logs and breakpoints.

[faint hornet]

I already know whats happening at runtime. what i don't understand is why is it converting my local position to a world position, even though i have it set to local position @cosmic rain

[cosmic rain]

Are you sure you're passing in a local position?

[faint hornet]

I'm setting the position in the inspector as a vector 3. does that not work?

[cosmic rain]

It does if you're setting the correct value.

Where are you calling the coroutine. Share more of the relevant code.

[faint hornet]

this is the position it ends up in at the end of the animation.. but you can see the vector 3's at the bottom, the start position, then the end position. it's not even close

[cosmic rain]

Rect position != Local position.

It's relative to the anchors.

You're looking at the wrong thing

[faint hornet]

what? iv'e always done it this way and it works ecept now? what do you mean

[cosmic rain]

It probably just happened to match.

It depends on the anchors setup

[lunar dirge]

I've been working on a tower defense game where there are plots and using the OnMouseDown function you can place a canon.
The problem is to delete a canon you also use the same function and it only deletes the canon 1/5 times.

[faint hornet]

@cosmic rain
so yeah this is now working

IEnumerator Move(Vector3 start, Vector3 end)
  {

    float elap = 0f;
    movable.anchoredPosition = start;
    Debug.Log(start);
    while (elap < 1f)
    {
      elap += Time.deltaTime / moveAnimation.duration;
      elap = Mathf.Clamp(elap, 0f, 1f);
      float eval = moveAnimation.animationCurve.Evaluate(elap);

      float y = Mathf.LerpUnclamped(start.y, end.y, eval);
      movable.anchoredPosition = new Vector3(0, y, 0);
      if (elap >= 1f)
      {
        movable.anchoredPosition = end;
        break;
      }
      yield return null;
    }
  }```
But this makes no sense, i've never done it this way, ive done it using local position hundreds of times

[cosmic rain]

Then you were doing it wrong all along.

[faint hornet]

well clearly i'm tippin or something, because it's always worked. whatever. i feel like a fkn insane person at this point

[lunar dirge]

i need this to be done asap I'd appreciate any and all the help I can get

[sudden stump]

Add an if statement to prevent both functions from... functioning at the same time

[lunar dirge]

they are on two different scripts and game objects

[sudden stump]

You should make a general PlayerInput script that calls both of those

That way you can control which one should function first

[lunar dirge]

alrightr will do

thank you for your advice

[cosmic rain]

As I said, it just happened to work, because of a specific anchors configuration. You're not insane, you just had a bug that went under the radar.

[tall salmon]

i finally wrote what i meant

srry i was so slow, was grabbing breakfast

(a variable that selects a spawner in wich to spawn the enemy)

i still need to mess with the y or x of the vector 3 but thats what i was going for

[wide dock]

Most of this is repetition

[tall salmon]

i know

[wide dock]

Just select a spawner based on the number and save it into a local variable

and use that instead

[tall salmon]

exactly what i was looking for

[tall salmon]

could you elaborate on that?

i dont get it srry

[wide dock]

Spawner spawner = choosenSpawner switch
{
  1 => upperSpawner,
  2 => lowerSpawner,
  3 => leftSpawner,
  4 => rightSpawner
};

Vector3 position = new Vector3(spawner.transform ...
Instantiate(...
tillNextWave = 4f;

Or just make yourself an array of spawners, get a random index from 0 to 3, and choose the spawner from the array based on the random index you get

[tall salmon]

i get the main idea ( or logic) but i dont understand some things like what spawner spawner means

or what switch is

[wide dock]

Spawner is whatever type you have for your spawner

Maybe even a GameObject, idk what you did there

[tall salmon]

i created a empty gameobject as a reference for the position

[wide dock]

As for a switch, that's a basic C# keyword, it would be wise to learn the basics to have an easier time with Unity

[wide dock]

Then basically what I did, but replace Spawner with GameObject

[tall salmon]

yep im basically using unity to learn c#

[tall salmon]

not the wisest but the funniest way of doing it i think

[tall salmon]

i´ll look into it

[wide dock]

Personally I don't think it's the wisest thing to do, but whatever. It's best to learn one thing at a time

[tall salmon]

im "not" learning any unity

im just using default sprites and concepts

and trying to create random mechanics of games

searching my own way to answer the problems of creating that mechanic

[wide dock]

Fair enough. Still, going through a C# course wouldn't hurt

[tall salmon]

probably

[wide dock]

It's like trying to operate a machine by yourself via trial and error when the manual is right next to you

[tall salmon]

yes

i know im dumb

[wide dock]

Doing stuff by yourself is fine, but that comes after learning the basics properly

You'll have a lot of opportunities to do so.

[tall salmon]

i try to learn how something works

like transform.position

for example

and once i have that in my grasp i will use it

[sudden stump]

More proof that #archived-code-general is the actual #💻┃code-beginner

[tall salmon]

i use the code general because its general

i didnt know it was meant to a " medium level"

srry if so

my logic was code begginer is for begginers to have some sort of discussion and so with code advanced

and code general as just where everyone can talk

[wide dock]

Well, and guess how can you learn everything about it - from the docs

[tall salmon]

and since im no advanced but needed help from advanced i write in general

[tall salmon]

they confuse me a lot

i try to read it but i just cant get around it

[sudden stump]

Use ChatGPT to simplify it

[wide dock]

No worries, no one will hunt you down for asking in the general code channel

[tall salmon]

i know i know

just wanted to make a point

[tall salmon]

my friend is doing exactly that in some sort of way

but he also uses it to write code and all

[sudden stump]

I wouldn't recommend using ChatGPT to write code

[tall salmon]

i dont think the last part is recommended

exactly

[sudden stump]

In fact, normally I wouldn't even recommend using it for anything code related

[tall salmon]

maybe for understanding the docs it can help tho

[sudden stump]

Unless you have 4.0 but even that isn't good enough for coding, only simplifying the docs

[tall salmon]

what is 4.0 ?

(im from europe)

[sudden stump]

ChatGPT has two models, 3.5 and 4.0. Later is more advanced but costs money

[wide dock]

Well, one thing to learn besides C# itself is learning how to read docs. But I believe that most of the confusion comes from not understanding the basics of C#, and thus the wording used in the docs may confuse beginners. That's why you should start with C# basics rather than Unity + C#

[tall salmon]

ohhhh i was thinking you meant smth like 4.0gpo

[tall salmon]

probably

lemme search for a doc i was trying to read

[sudden stump]

Learn C# up to events/interfaces

That should be enough

[tall salmon]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/arrays

[wide dock]

That's pretty vague, since the order of learning depends on the course used

[tall salmon]

what i dont get is what does the T after IList mean

or that type of things

[sudden stump]

Most courses put both of those things somewhere in the middle of intermediate coding

[rigid island]

T is a generic type

[tall salmon]

my boy

[calm echo]

I would recommend staying away from the microsoft docs until you have a good understanding of the language, as it contains alot of implimentation specifics that are not important until you are more advanced. Just try googling what you want to learn and click around until you find a site that explains it well for you

[sudden stump]

If you want a list, then learn those;

variables

data types

conditional statements

switch statements

collections (arrays, linked-lists, lists)

loops(for, while, do)

functions/methods

references

scope(global, local, parameter)

LINQ

sorting algorithms

inheritance

composition

classes

abstract classes

interfaces

polymorphism

SOLID

namespaces

events

exception handling

Debugging

break points

algebra

calculus

basic trigonometry (you don't need to be a math genius bit you need to know enough to at least find an answer on google)

[rigid island]

wtf is this

[tall salmon]

xD

[sudden stump]

What you should learn before going into unity, hopefully

[tall salmon]

makes sense

ill try to learn those

its similar to how i was doing things atm

but just specified

[wide dock]

Also have this. Never used w3schools but heard people talking good things about it.
https://www.w3schools.com/cs/index.php

[sudden stump]

Get C# player's guide

Best pure C# book

[tall salmon]

i was searching problems which needed exact answers (or answers that i thought were correct ) and then started investigating

so i wanted to make a counter that goes up each time i press smth (variable)
i wanted to make that when it reaches 10 it does smth (statements)

and so on

not the best way

ik

but the one i find to enjoy the most since i get to see some results of the work i put in

[wide dock]

While that is completely fine, it would be good to know the basics, just to root out 95% of the problems you might have at this stage.

[tall salmon]

idk how to word it but

if i write code in c# where is a visual representation of what im doing

like for example the mythic hello World

i dont know where it is displayed

(thats what i mean)

[wide dock]

Well, things don't always come with a visual representation

[tall salmon]

i mean, how do i know if something is working if i dont see it

[wide dock]

You'll eventually be in situations where you code for a week and it's all logic which you'll see "visually" in another week, maybe

You print values to see what happened and if it worked, etc

[tall salmon]

if i dont see the text "Hello world" how can i know that i scripted the hello world correctly

[tall salmon]

thats what i meant

i didnt mean smth like: yippe my character moves but more like okay i managed to change a Rb2D.velocity change with what i wrote

[wide dock]

Either way, if you commit to it, then learning the basics of basics will take you a few days

And you'll need the basics

And yeah, I'd now better get back to work, since I'm highly overstepping the "free" time that I've got 😆

[tall salmon]

im currently also getting my language certificate (or however its called) so im just side-questing programming (this doesnt mean i dont like it or smth like that but rather that i dont have that much "free" time to dedicate)

[tall salmon]

gl with everything!

you seem like a real/chill person

[wide dock]

Well, yes, I am real (at least I hope so)

[wide dock]

Thanks

[cosmic rain]

Code general means we expect certain basic knowledge from you. Like the C# basics, debug methods and the ability to configure your environment. If you are not able to these things, better to ask in beginner as then the expectations towards you would be lower and we would explain things in ways better suited for beginners.

[sudden stump]

That's code beginner?

I thought it was for those with basic knowledge like methods, if statements and fields

[cosmic rain]

What?

[sudden stump]

#💻┃code-beginner is for setting up the IDE, and #archived-code-general is for coding?

[cosmic rain]

No.

Code beginner is for beginners that potentially don't know anything at all. Code general expects you to have certain understanding and knowledge of basics.

Both are for coding.

As for setting up ide, isn't really a coding question in the first place, but if you were to chose a channel, beginner would suit it better.

[sudden stump]

25% of questions in beginner are asking how to set up unity or the ide

[cosmic rain]

Don't know about 25%, but yeah, there are many questions about it, which doesn't contradict what I said.

[dusky niche]

made a weapon switching script with animations
due to that I used coroutines
It waits for the animation to finish before deactivating a weapon object
can anyone check if it's done correctly?
https://paste.ofcode.org/ZT2mLetcyrCCyiqrng7GgL

[dawn nebula]

What would you say is the split between #archived-code-general and #archived-code-advanced

[cosmic rain]

Hard to say, but I like to think of it as a channel you write to about issues that no one would be able to help with probably.😅

[dawn nebula]

The "I'm deep in the rabbit hole, get me out" channel?

[cosmic rain]

Yeah, but that definition is also applicable to beginners that think that their issue is unsolvable, while it's really something simple, so It's hard to say.

[dawn nebula]

There's always a smarter fish.

[cosmic rain]

I guess, it's a channel you'd write to after going through documentation, manual and tutorials and still unable to solve it.

And debugging of course

[dawn nebula]

In my own mind I usually put the divide between beginner and general at ~3 months of experience.

And advanced is just some hyper specific nonsense.

[cosmic rain]

Yeah, I guess I'd agree about the "non specific nonsense", but regarding experience time it's really vague. I've seen people that struggle with basic C# after months or even a year of doing unity, simply because they didn't learn properly.

[dawn nebula]

I'll admit to having been in an odd state within my first year. I was doing some relatively complex stuff like function callbacks, A* pathfinding and rule engines.

But was unsure how to build a console app executable >_>

Because I literally never touched regular ass C#.

[cosmic rain]

I'd say it's more about mindset, than specific knowledge. If you know you can go through the docs in a few hours and figure out how to build a console app, you've graduated being a beginner.

[dawn nebula]

That's fair.

[cosmic rain]

When you're a beginner you don't even consider that as possible.

[dawn nebula]

Honestly even now there's a few "intermediate" concepts I really should have a better handle on. String manipulations is one of them. I really have never used Regex all that deeply.

Idk in game dev you're not doing crazy string shit.

[lean sail]

you rarely need to know proper regex tbh, only really for when you are parsing something that wasnt yours to begin with

if you need complicated regex on a string you made, theres likely a easier way to do things

[dawn nebula]

Regex is probably a higher level example. I still tend to go "Wait, how do I get this substring?" every so often.

[lean sail]

🤷‍♂️ ill look up the syntax still to this day and ive been coding for about 10 years now. maybe because ive done it in different languages and dont remember which method was which language

[dawn nebula]

This field is too deep man.

I have an odd combo of physics simulation and computer graphic knowledge baked in.

While my handle on networking is eeeeeeeh.

I wish I could hold a fraction of the power Ben Golus and Freya Holmer wield.

[lean sail]

You can say that about a lot of fields, it just so happens that computers are used to do work for other fields. Anyways if you truly want to get better at raw coding skills, there is always stuff like leetcode or whatever website is popular these days. Game dev is really just a matter of producing something that runs. In solving data problems, usually these websites will give you a time and memory constraint so you cant just do whatever you want to get the answer

[molten timber]

i will paypal anyone 10 pounds if they help me with my problem (My problem is that when i pull out my gun the gun doesnt want to shoot ive been following a tutorial from a guy called HawkesByte and when i am this part where i cant shoot when i take out my gun its quite useless please help lmao)

so the gun script is working but when i pull it out it doesnt work and i cant see the mistake

So who sets isActiveWeapon to true ?

[molten timber]

No idea

should it be false?

@west lotus

[wide dock]

Do you have any idea what the code does or did you just blindly follow a tutorial?

[molten timber]

i know a little about the code but kinda blindly follow

but learnt underway

[wide dock]

isActiveWeapon should obviously be set to true once the gun is taken out, otherwise nothing in Update() will run

This does not happen neither in the gun nor inventory script

[molten timber]

Well what can i type to add it

could you give me what i should typ eor

Casue i am just learning as i go on with unity

[latent latch]

If something isn't working and your code isn't riddled with debug.log then you're missing that crucial step of debugging

unless you're using breakpoints

[molten timber]

can you help me fix it

[latent latch]

if you're following a tutorial, I'd just go over it again and make absolute sure you're doing everything correctly as they do it

[molten timber]

I am 100% ive followed the tutorial fully

[latent latch]

cause now instead of you fixing it, you got other people fixing someone else's code ;)

[molten timber]

but i am not gonna lie i dont remember the videos name

[wide dock]

Either just get rid of the boolean entirely and just keep the weapon GameObject disabled, or make some kind of item interface with OnEquip() & OnTakeOff() method which handles switching it to true/false

Either way it's a bad idea to follow a tutorial without understanding everything presented there, as you can see by yourself right now

One small thing to change and there's a problem, which wouldn't exist if you understood what the code does from start to finish

[molten timber]

are you on about inventory script

[molten timber]

yeah but than nobody would begin with game development if you cant learn as you go

I started a few months ago

and i fairly think its going well

Its just that this is the first problem ive had resolve to this

but thats why i said i will paypal any1 10 pounds if they fix my code

Which seems fair

[wide dock]

IItem interface with OnEquip() & OnTakeOff() method, implement it on the Weapon script, store IItem instances in inventory, call methods when needed.
Can't help more beyond that

[molten timber]

do you want me to copy what i told it do in the inventory script over to the weapon script?

[wide dock]

This is not what I said

[molten timber]

yh

well you will get 10 pounds if you help me fix this problem

[wide dock]

I just described how you could do it

1. Make an interface
2. Make your inventory slot store references to instances implementing this interface
3. Implement this interface in the weapon script. OnEquip() should turn the boolean to true, OnTakeOff() turns it to false
4. Call appropriate methods at appropriate time

[molten timber]

in the weapon script or inventory

@wide dock

[wide dock]

And where do you think

[molten timber]

weapon

[wide dock]

I reckon you're asking about point 4?

[molten timber]

yh

[wide dock]

Then why would ever weapon call the interface methods

It's the inventory/slot that stores the instance, and it's the inventory/whatever which pulls out the item

Thus it should be the inventory or whatever pulls out the item to call the method

How else would the weapon know it's being pulled out and equipped

A weapon has no concept of inventory, it can just be either used or not - how it happens depends on how you implement it (inventory, interface, etc)

[tall salmon]

got it!

[spring flame]

Is it possible to do collision checks between intersections of colliders?
On the attached image I have a player and 2 colliders. One is green and one is Red.
The player character would have a set of masks describing what it can collide with. On the attached image player can collide only with red and green at the same time, so effectively it's the hitbox that is the intersection of red and green.

[leaden ice]

Not with anything built in.

[magic briar]

Hello, how to add libraries of sensors into unity? They arent in git. They are only downloadable from their web and support .NET. Just add them to Library folder?

[leaden ice]

You'd need to dynamically generate the intersection as a polygon collider

[leaden ice]

https://docs.unity3d.com/Manual/UsingDLL.html

[spring flame]

Any battle tested and performant libraries for that you would recommend?

[magic briar]

Uff. Ty, I have never experiences with dll

[hard viper]

you would need to actually add logic. You read each individual collision, and log it.

you don’t need to overcomplicate by defining a collider for the intersection

just have a monobehaviour that keeps a state to log which colliders have been hit, so you know if you are in the intersection

[delicate flax]

you can't get something exactly like with with any of the built-in systems. the system you need is called "boolean mesh/shape creation", using that you can create a shape and then create a polygon collider from that.
buuuuuut, if your use case is specific enough you can probably cheat. like in the image you posted. if red was a trigger collider, you could make it so that the player only collides with green if it's also colliding/hitting red.

[hard viper]

don’t make a collider/geometry for the intersection. that will only cause spaghetti

if you need the force, to be conditional, then you should handle that with custom logic

like, if player is on green, set layer overrides for force receive to include the red. Otherwise, set it back off

[tall salmon]

i searched a video that talks about the switch conditional and wrote a bit in my code

i´ve noticed 1 main issue, visual studio recommends me to use default because not all possible cases have been covered but when i write it it tells me it is not valid

i did some research and found that it got patched a while ago and default ceased to be used

[thick terrace]

what did you try?

[tall salmon]

is it to me?

srry im kinda slow

kewk

[thick terrace]

yeah, what did it say isn't valid?

[tall salmon]

ill show you

[wide dock]

not default, write _

[thick terrace]

in a switch expression you write it as _ => upperSpawner for example

[tall salmon]

ohh

[wide dock]

you only write it as default if it's a regular switch statement

[tall salmon]

and isnt it a regular one?

[wide dock]

switch (variable)
{
  case 1: ... break;
  default: break;
}```

[thick terrace]

it's a switch expression, totally different construct despite the name

[tall salmon]

ohh

[tall salmon]

another thing

it has to do with math/logic

idk if you can help me with that

[wide dock]

Write what is the issue

[tall salmon]

ill show you the gameobject positions for reference and then explain

[spring flame]

statements don't return values, expressions return values. 1+2 is an expression. float x = 2 is a statement; You can use expression in an if(...) contition check for example, but you cant use statements.

[tall salmon]

i wanna do that it chooses a random x if the spawner is = to upperSpawner or lowerSpawner
and if its leftSpawner or rightSpawner that the randomized transform.position is y instead of x

[spring flame]

statements is a "do thing" kind of syntax and expression is "calculate and return the value" kind of syntax

[tall salmon]

what i had written b4 was this for left and right :Instantiate(enemy, (new Vector3(position.x , position.y + Random.Range(-5.59f,5.59f), position.z)), transform.rotation);
and this for upper and lower: Instantiate(enemy, (new Vector3(position.x + Random.Range(-10, 10), position.y, position.z)), transform.rotation);

[humble kraken]

Can someone help me please? I have a missile system, where I set point A and point B. The missile spawns in point A and moves to point B until it reaches the point. I want to implement a system, where I can animate the path (arc, curves and etc).

• All curves will be strechted along the path (A →
  B). the curve is applied relative to the path.
• The „time“ of the curves is the normalized time of the
  animation duration (0 = start of animation, 1 = end of
  animation).
• The value is the displacement on a single axis (X or Y
  or Z) in world units.
• Tiling means how often the curve is repeated along the path.
• Scaling means how much the curve values (displacement along the up axis) are scaled. This way you can keep your curve values in a nice 0 to 1 range, yet scale them up as much as you need.
• Each curve should start at (time: 0, value: 0) and end at (time:1, value: 0). If the value is not zero at the end then the target will be missed and it will look very odd if the curve is tiled.

However, I can't figure out how to make the missile to move along the curve. Currently, it just instantly jumps to the scale, instead following the arc or curve i set. Help me please

[tall salmon]

got it

[hard viper]

also you should use enums, or you will get very lost

[tall salmon]

dont know if it was meant to me but i learned something

xD

[tall salmon]

what is an enum?

[spring flame]

you can check in C# docs

[hard viper]

it’s like a definition of a class that has specific named values for int values

[spring flame]

basiaclly a named alias for int values

[tall salmon]

ohh

i think i kinda get it

[spring flame]

with bonuses like it shows a dropdown in inspector if you use enums, instead of int fields

[tall salmon]

surely will check it out once i have lunch

[hard viper]

public enum Cardinal { Up, Right, Down, Left}
defines a type. You can now write Cardinal.Up, and that is basically equivalent to 0. But now when you read your code, you know wtf it means. Instead of just seeing a zero

[tall salmon]

makes sense

[spring flame]

and you can assign custom int values to enum keys as well: enum Cardinal {UP = 0b1000, DOWN = 0b0100, LEFT = 0b0010, RIGHT = 0b0001} (this one uses binary literal syntax)

[tall salmon]

btw idk if yall have context but i have thought about how i can merge both of them in one since i want to use switch but i havent come to a conclusion yet

i dont know if its just not possible

wich may be

[hard viper]

enums and switches usually go together

[tall salmon]

or if im just slow-ish

[hard viper]

almost every one of my switch statements uses switch of an enum type

[wide dock]

Either do that manully depending on choosenSpawner value, or preferably make a custom class for the spawners to actually use them as spawners rather than just a position, and place that logic there.

Simply have some fields there representing X and Y range and use that to get the position

[hard viper]

int and enum types can be cast into each other.
(int) Carinal.Up is 0.
(Cardinal) 3 is Cardinal.Left

[wide dock]

for top/bottom spawners Y range can simply be [0 ; 0]

[wide raft]

So i have a slight problem, when i load my project on my desktop my map and character show up correctly, but when i try to pull the same project down from github onto my laptop, the scene im working on is empty... (using git lfs btw), this has not happened on other scenes so im confused

[tall salmon]

im going to copy paste that and look into it further once i am finished eating since my family reclaims me

ty tho caesar

you are being my saviour like navarone

ty all who helped!

[spring flame]

do you open correct scene? :D

[calm bobcat]

Why are the parameters in the following code not being recognised correctly? Also, the EditorGUILayout.ObjectField(string,Object,System.Type,bool); is marked as deprecated, meanwhile this is clearly wrong...

[wide raft]

😂 yes i do

[calm bobcat]

When I do the following outside of a function, it works like it should

[spring flame]

are scene file contents the same on your desktop and after you pull it from git?

[wide raft]

do you mean the window that shows assets inside the scene ? if so then no, there is nothing inside it. but the prefabs used in the scene are present

in their respective folders. just not in the scene, like at all

[spring flame]

I mean the actual .unity* file as it is serialized on the disk. Is it possible that the contents of both files differ in their textual format

[wide raft]

uhm i dont know, how would i check that ?, have to copy from git and compare ?

[spring flame]

hmmm, are you new with git?

[wide raft]

not exactly, but its been a while since ive had to do anything major

[spring flame]

you would generally do a variant of git diff <revision SHA> -- <file path> or something like that

for example when I'm inside my local git repo in the Scenes directory I can do git diff origin/master -- someScene.unity

which will show the diff between local file and what's in git

maybe you just didn't pull the changes or something

[hard viper]

idk why your #if directives aren’t gray. Are you sure ur IDE is configured properly?

!Ide

[tawny elk]

💡 IDE Configuration

If your IDE is not autocompleting code
or underlining errors, please configure it.

Select one:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)
• VS Code
• JetBrains Rider

[hard viper]

#if UNITY_EDITOR should be grey.

[leaden ice]

why would unity editor be grey

they're almost definitely compiling for unity editor currently

[calm bobcat]

i do have the package installed

and the unity extension from the vscode extensions

[hard viper]

because it is in a compiler directive. my compiler directives are always grey

[leaden ice]

the active ones should not be grey

[hard viper]

is that not normal? It’s been like that for me on both mac and windows

hmmm, I’ll need to see if maybe my settings are wrong lol

[calm bobcat]

even after explicitly mentioning which parameter is what, it gets an entirely wrong (and deprecated for some reason) overload

[wide raft]

did a git diff nothing showed up

[leaden ice]

nvm i misread

[calm bobcat]

it is a c# feature

you can get a different parameter with that

to like get a default variable without typing it in a specific order

[leaden ice]

Yes I know

[spring flame]

you could do git fetch because maybe your lcoal repo doesn't know of new changes in the remote then do git status to see if you are maybe in progress of some kind of rebase/merge or something and whatnot and possibly check if you actually pushed the changes to remote from your desktop

[chilly surge]

You should not be using the "VS Code Editor" package in Unity, you should use the VS one. See the documentation of the Unity extension.

[calm bobcat]

should i remove the VS code one?

and only keep VS package?

[chilly surge]

Yes, remove it and use only the VS one.

[calm bobcat]

will do rn

[chilly surge]

It might not be what's causing the issue that you are having though, just a passing observation.

[calm bobcat]

i'll try it tho

installing back is easy so yeah

[chilly surge]

The reason is that C# Dev Kit actually uses the same core as VS, I guess they just didn't bother updating the VS Code Editor package since it was marked deprecated a long time ago, and just tell people to use the VS Editor package.

[calm bobcat]

do i restart vscode afterwards?

i'd assume

[chilly surge]

🤷

Might as well.

Click the regenerate project in Unity and then restart VS Code.

[calm bobcat]

where is this option again?

i used to just delete the project configuration files and re open vscode lol

[chilly surge]

IIRC in Preferences.

[calm bobcat]

found it

hmmm nothing changed

what's so different about using it in here anyway

[leaden ice]

i mean your error is pretty straightforwrd

[calm bobcat]

but that's an object already???

[leaden ice]

No it's a T

T can be anything

it could be int

[calm bobcat]

oh?

[leaden ice]

you need to constrain the generic type if you want to make sure it's a UnityEngine object

[calm bobcat]

like if (T is UnityEngine.Object obj) in a way?

[leaden ice]

public static void HandleCustomInspector<T>(this List<T> list) where T : UnityEngine.Object for example

[calm bobcat]

OH

thank you!

didn't know what where did when i was seeing it, that's helpful :)

thx 👍🏻

it did work

[prisma birch]

How can I achieve this style of enum category options in Unity 2023? [InspectorName(Category/Option)] used to do it but it seems to no longer work and displays all my options in a super long list.

[limpid siren]

How can i access in code this mesh inside the gameobject that i already have access:

gameobject.GetComponent<Mesh>() just return null

[wide dock]

I ain't a 3D expert but you probably want to get the MeshFilter and get the mesh via the mesh property

[limpid siren]

backpack.GetComponent<MeshFilter>() returns null

[limpid siren]

/\

[wide dock]

The mesh filter is probably on a child of the actual gameobject

[knotty sun]

Show the inspector so we dont have to guess at the setup

[tardy crypt]

I am writing some code and I want to test it out. To do this, I made a console application in VS with some test code in the directory structure of my unity project. After testing and whatever, Unity is telling me that there are multiple precompiled assemblies with the same name (<filename.dll>). I just want to be able to test my unity code separately from unity in some simple way. Can anybody tell me how what I'm doing is wrong and how I should go about correcting these issues?

[leaden ice]

Use Unity Assembly Definition files

[spring flame]

you have to access the asset, so it would be something like AssetDatabase.LoadAssetAtPath<Mesh>("<pathToAsset>")

[tardy crypt]

quick stupid fix appears to be just to play an assembly definition into the folder that has my console tests? that way, unity will just ignore that folder and subfolders?

[limpid siren]

My asset is in a list of gameobjects for possible dresses

[knotty sun]

The inspector of the GameObject not the Model

[limpid siren]

this ?

[spring flame]

Asset is what is in the library. Component is what is attached to GameObject.

not sure what exactly you want, but just as I wrote, AssetDatabase.LoadAssetAtPath<Mesh>("<pathToAsset>")

you need a path to asset

in any way you want, serialized in inspector or something

[knotty sun]

yes, So you have a SkinnedMeshRenderer which has a mesh property

[limpid siren]

Yes but i have all the equipments in the GameManager List <GameObjects>

[limpid siren]

that's not the problem, im able to change it

all i want is to select all the objects and drag into a list

if i do a list of Mesh instead of gameobjects and drag one by one to the list it will work

[tardy crypt]

no that didn't work... alright i'll take a look more closely

[limpid siren]

but i need to drag the children

[knotty sun]

your question was 'How can i access in code this mesh inside the gameobject'

[limpid siren]

i want to drag them all

so set the list as a list of gameobjects

[limpid siren]

yes, but the object i want to access the mesh is this one:

i want to access that to be able to set on the Skinned Mesh Renderer that i already checked that is working just fine to change, i just need to access the Mesh from the gameobject

[limpid siren]

Tooster, so u r saying like that?

instead of the pathToAsset can i use the gameobject with the mesh inside?

[spring flame]

you must use asset path

[leaden ice]

If you already have a reference to the thing you wouldn't be using AssetDatabase at all

[limpid siren]

i mean yes XD

[spring flame]

that is also true

[chilly surge]

What do you mean by "test it out"? Test as in actual tests like unit tests/integration tests/etc? Or as in just some quick throwaway code to try out C# stuffs?

Because if it's the latter, just move the "test" project outside of the Unity project's folder.

[tardy crypt]

it's going to be unit testing with a console app. The class I'm testing is obviously part of the unity project but the test code that tests the class is going to run in a console app, not within unity itself. Will moving the test project outside of the Unity project folder work if I'm including a file in the Unity directory structure (the class being tested) in that project itself?

[chilly surge]

Nah, that suggestion was for the latter which isn't your case. Was just making sure.

Is there a specific reason that you want to run your tests outside of Unity? There is the Unity Test Framework package you can use to directly run your tests inside of Unity.

[tall salmon]

isnt that kinda what i had in the first place? I suppose i can do switch for both of the ones that need a random x and for those who need the y, and what you say about making them actual spawners, isnt it something that would just take me much more time?

(got back from lunch)

[limpid siren]

var newBackpack = GameManager._instance.listSkinsBackpacks[0].transform.GetChild(0).GetComponent<SkinnedMeshRenderer>();
backpack.sharedMesh = newBackpack.sharedMesh;

it worked like that guys 😉

[tardy crypt]

No specific reason, I just didn't want to deal with the Unity interface in doing the tests. I have used the Unity unit tests before so I can take a look at that. Thanks.

[limpid siren]

i needed the getchild(0), i iterated all the childs the check which

[wide dock]

Depends on how you implement it, but overall it would be way cleaner to have something named "spawner" act like a.. spawner.

[tall salmon]

i guess so but since i already did it like this i think there isnt a major issue right?

[wide dock]

If you want this script to act like a spawner then rename these fields for more clarity, so for example "spawnPoint"

And make it into a small custom class so that it supports a spawn range

[tall salmon]

small custom class?

[tall salmon]

great idea

[chilly surge]

Valid reason tbh, but it's probably lesser of the two evils.

[tardy crypt]

which is the lesser? dealing with unity's stuff?

[chilly surge]

Yeah.

[tardy crypt]

alrighty...

[knotty sun]

pro tip, if you are sharing code between a Unity and a VS project make sure to use the Add As Link option of add existing file in your VS project, that way you only have one version of the code

[tardy crypt]

hmm... i added the "existing" item... i assumed it didn't make a separate copy but... did it?

[knotty sun]

yes

[tardy crypt]

ahh...

[knotty sun]

The Add button is actually a drop down with Add as Link as the other option

[wide dock]

public class SpawnPoint : MonoBehaviour
{
  [SerializeField, Min(0)] private float m_xRange;
  [SerializeField, Min(0)] private float m_yRange;

  public Vector2 GetRandomPointInRange()
  {
    Vector2 pos = (Vector2)transform.position;
    float xRand = Random.Range(-m_xRange, m_xRange);
    float yRand = Random.Range(-m_yRange, m_yRange);

    return new Vector2(pos.x + xRand, pos.y + yRand);
  }
}```Something along those lines, simply replace `GameObject upperSpawner` with `SpawnPoint upperSpawner`, etc (or make an array of these to make it simpler if the chosen spawner is completely random)

[tardy crypt]

i see.

i just finished a C project where I could just specify exactly what is compiled, where to put the .obj files, and what .obj files to link into an executable... unity and vs's system is way more complex and i still have no idea how it works...

[tall salmon]

i had an idea like that but i want it to spawn outside of camera

with that thing it would spawn in camera and potentially on top of the player insta killing them

[wide dock]

So what's the issue with that? You can still spawn it outside of camera with this

Simply have an Y range of 0 for top/bottom spawners

and X range of 0 for left/right

[tall salmon]

yeah but then its kinda the same of what i have?

or maybe im confusing things

[wide dock]

Well, it's cleaner, you keep all the position logic within the SpawnPoint class

[tall salmon]

thats true

[wide dock]

All you have to do is use the switch expression from earlier (or an array) and call the method once

[tall salmon]

instead of bruteforcing thru it with writting random.range each time

[chilly surge]

Where is your VS project currently, is it in Assets/ of the Unity project?

[tardy crypt]

yes, Assets/Scripts/Tests/ConsoleTests

[tall salmon]

but the switch expression doesnt work for this since it cant be written in the same " formula" that it spawns randomly and works for upper and lower at the same time as it does for left right without spawning in the camera

i think

[chilly surge]

Yeah don't do that, things in Assets/ are treated as game assets and added as part of the Unity project.

[tardy crypt]

alrighty...

[chilly surge]

Simplest is just move it into like Tests/ and that should get rid of the double compiling issue.

[tardy crypt]

ok i'll do that

[wide dock]

public class Spawner : MonoBehaviour
{
  [SerializeField] private SpawnPoint[] m_spawnPoints;

  private void SpawnSomething(GameObject prefab)
  {
    int spawnPointIndex = Random.Range(0, m_spawnPoints.Length);
    Vector2 position = m_spawnPoints[spawnPointIndex].GetRandomPointInRange();
    GameObject instance = Instantiate(prefab, position, Quaternion.identity);
    ...
  }
}```That's all you need

[tall salmon]

i think thats far more advanced of what i can comprehend and do

[arctic plume]

Hey, sorry if this is a stupid question, I'm not that experienced with coroutines and timing things in c#, but why does the code after the if statement still immediately execute?

    public void buttonPressed(String choice)
    {
        if (firstTime)
        {
            StartCoroutine(sitCharacters());
        }
        ....//rest of the code here

Shouldn't it wait since it's a Coroutine? Again I don't have a lot of experience doing this so I'm assuming I have a complete misunderstanding on how it works

[tall salmon]

but atleast i now know i was wrong and that there was a way of doing it with switchs

[wide dock]

Not really that advanced.
Same as you have a GameObject field, you can just have an array of SpawnPoints
Choose one at random, call the method to get the position and spawn the thing you want to spawn

[surreal blaze]

I believe they may run in parallel on the main thread, so no it wont wait.

[tall salmon]

yea i need to learn how arrays and lists work

that was somewhat my next plan

[surreal blaze]

If you need something happen at the end of the coroutine just put a bool = true at the end of the sitCharacters coroutine, then just put ....//rest of the code here inside an if bool = true

[tall salmon]

i know this can sound weird and you surely are busy but if you have the creativity and the will to do it, do you know any mechanic that i could add? the game is a basic top down shooter with a wave generator (which i need to polish a bit)

[knotty sun]

you do indeed misunderstand. When you start a coroutine that routine will execute immediately until it hits a yield statement. The code will then continue to execute with the statement after the StartCoroutine

[wide dock]

Well, switches are a thing if you really don't want to use an array, but if you can use an array, then use it, since a switch would require you to expand it every time you'd add a new spawner (and using an array is just simply faster and takes less lines to implement)

[tall salmon]

yeah i need to get myself to learn how arrays work fr

have been thinking about that for 2 days or so

[wide dock]

I'd need to know a lot more details than that, and it would be probably a topic for either #archived-game-design or DM

[tall salmon]

its just that simple tbh

it doesnt have more than that

kewk

and srry for using the wrong chat ig

[wide dock]

No worries, you probably won't get eaten by any moderator as long as you don't start a full-blown 12-hour conversation about something unrelated to the channel you're in

[tall salmon]

that makes them comprehensive

[wide dock]

But yeah, if you're looking for inspiration then #archived-game-design is the place for it

[tall salmon]

alrighty!

tyy!

[spring flame]

I thought about it and it wouldn't produce correct results on it's own.

for example here, I would have logged that it collides with G and collides with R, but the intersection doesn't exist so it shouldn't collide with anything, yet it would be detected as if it collides with both

[delicate flax]

well, add an extra check that G and R also have to collide? else they can't intersect

[elfin tree]

What's the best way to either make LayerMask out of a list of LayerMask, or how to input a multi-layer layer mask in inspector (to be used with Physics.Raycast)

[spring flame]

this approach also wouldn't work in all cases:

[leaden ice]

public LayerMask mask;```

[delicate flax]

I don't understand, LayerMask is a bitmask, so you can already set multiplie layers?

[leaden ice]

there's no need for a list or anything

you can select multiple layers

[elfin tree]

oh wow you're right (it was that simple)

thanks

[delicate flax]

that's true, and that's why I said in my original answer that the 'cheat' method might only work if your game design allows it, since it's not a general solution.
but are you going to have any level geometry that looks like the image you just posted? and even then you can get more clever with the 'cheat' and adding more rules.

[spring flame]

Yeah, I plan to have a geometry like that. I'll also be trying to sometimes have 3 (not sure if more) overlapping areas. I am thinking about something pretty crazy here, but maybe I will try something I've never seen before and render collision buffer in a compute shader, which I would handle manually for checking collistions?

as mesh intersection solvers could get a bit crazy if I ever wanted to go beyond simple convex shapes

[glossy wave]

when i set the LocalTransform of a variable like this:
LocalTransform value = new Unity.Transforms.LocalTransform();
is the value the LocalTransform of the object that it's attached to?

[leaden ice]

no you're creating a default struct there

it's basically going to be all zeroes

[hard viper]

that depends on the logic, which is a totally separate issue

do you need to make the red solid only on the frame after you are on green, or do you need to apply force from red only on frames where you are in contact with green

because the latter does not make sense with how contacts are generated at all

you can’t know if you are in contact with green until contacts are generated for it, but now you want to go backwards and redo the simulation with red counting as solid

or if you are just DETECTING collision, eg by collision callback, then there are no forces at all, and this needs to be detected by logic with a script, that keeps a record

it’s not clear if you are dealing with forces or callbacks

[gray vessel]

multiple instances of a material (these made in shadergraph) causes them to bug out and shrink and offset, anybody know why it might do this?

[calm talon]

how do you get code in OnDestroy() to run when deleting a gameobject in editor?

([RunInInspector] is not working)

[spring flame]

I don't know, but try [ExecuteAlways] instead of RunInInspector. I remember there being some bugs/differences with it.

[rigid island]

It works but You need to run DestroyImmediate not Destroy

[dusk apex]

That probably wouldn't fire in the editor like awake and start would not too. Maybe something like this https://forum.unity.com/threads/editor-callbacks-for-gameobject-creation-deletion-duplication-by-user-or-user-script.788792/

[rigid island]

it works

[calm talon]

there's no OnDestroyImmediate

[dusk apex]

I think he's deleting the object in the scene hierarchy

[leaden ice]

I think OnDestroy works as long as you have [ExecuteInEditMode]

[calm talon]

tried

[dusk apex]

Can you give us more info on what you're actually trying to do?

[rigid island]

[ExecuteAlways]
public class Destroy : MonoBehaviour
{
    [ContextMenu("Destroy")]
    public void Destroyit()
    {
        DestroyImmediate(gameObject);
    }
   
    private void OnDestroy()
    {
        Debug.Log("Destroyed");
    }
}

[leaden ice]

did you put ExecuteInEditMode on the class or the method?

it belongs on the class

[calm talon]

yeah that's it

[rigid island]

incase you dont believe me 😛

but yeah should prob explain what ur trying to do

[calm talon]

Take all the tiles of one tilemap, shove them into another that acts as a mask that lays on top for blood splatter effects

if I delete the tilemap, automatically remove all the tiles in that mask

Hello 🙂 I have a question about null references on screenshots. I'm using steamworks.Net (without any wraper I guess)
This null happens rare, not everytime. I'm out of ideas what can cause this.
In editor this problem don't appear and also when I'm trying to recreate this bug in build/launch from steam as player/ build with console - but no success. It's related somehow to esc (pause game) and steam layout? but how?

The funny thing is that everything is working correctly, but it's annoying to see this in player logs and don't have idea how to fix this. The game is released on steam, has working achievements and everything else.

[knotty sun]

I was hoping to see some unique commonality between the methods, unfortunately there's a great deal of that and so many things that could be null it's impossible to tell. you're gonna need to debug this to find the problem

[brave hazel]

Hello ! I have an error (UnassignedReferenceException:The variable rb of Player has not be assigned) and i don t understant my variable is not null

[agile rock]

hmmm ok thanks, I was hoping if here maybe someone have exactly the same problem and somehow fix it
I'm debuging this but zero result, no clue. If I will be able to recreate this bug then no problem but this is just a lottery

[rigid island]

what about during playmode
if it still assigned in playmode search for any duplicates in hirerchy view search t:Player

[main coral]

Thanks

[leaden ice]

Player can exist on more than one object

also your collider is referencing a destroyed physics material

[brave hazel]

well, what can I do now (sorry, if it's a stupid question, I'm a beginner)

[naive swallow]

Either clear the box or drag in an actual physics material

[leaden ice]

remove it

[heady iris]

This isn't the cause of the error, mind you

You probably have two Player components in your scene

You can search for all instances of the component by searching for t:player in the Hierarchy

[brave hazel]

Hmm , here ?

[heady iris]

in the tab that says "Hierarchy"

that's the hierarchy

not the Project window

[heady iris]

yes. search for t:player in the hierarchy.

[heady iris]

okay, so there's only one player

also, is there a reason you're not just sending screenshots

you can just log into discord on your desktop to paste images

[rigid island]

can u show the Player script

send it properly not a photo from phone

[heady iris]

I presume the Player script is overwriting the field with something else

[rigid island]

yeah was thinking that

[rigid island]

hmm yeahh looks fine here. Except ofcourse your Unconfigured IDE

[somber nacelle]

speed is also 0

[rigid island]

btw are you sure thats not an old error you just didn't clear console or something ?

[brave hazel]

I'm connected with iCloud on my phone

[rigid island]

but you're using a computer just send screenshots

[heady iris]

I don't see how that has anything to do with my question.

Sign in to Discord on your computer so you can send screenshots and paste code correctly.

[brave hazel]

I didn't change anything, I just closed it and opened it again

[rigid island]

closed and open what? Wipe the console and start game again, is the error appearing again?

[brave hazel]

I closed the project

thank you all, I was written rb and on unity it was written Rb in the variable and I modified it and it works rn

🙏🙏

[heady iris]

That was not the problem.

the inspector automatically capitalizes variable names.

I'm guessing you accidentally duplicated the Player component at some point, or perhaps cleared the field in the inspector while the game was running

Given how it was referencing a missing PhysicsMaterial2D, it's also possible you hit undo a bunch while the game was running and wound up unassigning the rb (and un-creating the material)

[brave hazel]

well now it doesn't give me any error. Should I continue with this project or make a new one from the beginning?

[heady iris]

It's fine.

[lean sail]

Continue on but configure your !ide and also setup version control if you arent using it.

[tawny elk]

💡 IDE Configuration

If your IDE is not autocompleting code
or underlining errors, please configure it.

Select one:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)
• VS Code
• JetBrains Rider
• Other/None

[lean sail]

Version control would show you if you deleted your physics material here, assuming it was pushed to the repo ever.

[calm talon]

map.CompressBounds();
foreach (Vector3Int pos in map.cellBounds.allPositionsWithin)
{
  if (map.HasTile(pos))
  {
    mask.SetTile(pos, map.GetTile(pos));
    mask.SetTransformMatrix(pos, map.GetTransformMatrix(pos)); 
  }
}

I have this code to copy the tiles over from one tilemap to another, with a material on the tilemap being copied to that acts as a sprite mask.
However, the sprite mask does not work until I manually draw over it

it does work with the small test tilemap (Yellow) but not the larger tilemap (purple) Third image is the outline of the full tilemap mask

I am trying to create simple third person character movement with the new InputSystem, however the player just moves on its own like it's holding down W and A the second I start up the game. I am using the default PlayerInput component that you get by just adding the PlayerInput component on an object. This is my Player Movement script:

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

public class PlayerController : MonoBehaviour
{
    public CharacterController controller;
    public float moveSpeed = 5f;

    private Vector2 moveInput = Vector2.zero;

    public PlayerInputActions playerControls;
    private InputAction move;
    private InputAction look;

    private void Awake()
    {
        playerControls = new PlayerInputActions();
        move = playerControls.Player.Move;
    }

    private void OnEnable()
    {
        move.Enable();
    }

    private void OnDisable()
    {
        move.Disable();
    }

    // Update is called once per frame
    void Update()
    {
        moveInput = move.ReadValue<Vector2>();

        if (moveInput.magnitude >= 0.1f)
        {
            Vector3 direction = new Vector3(moveInput.x, 0f, moveInput.y);

            float targetAngle = Mathf.Atan2(direction.x, direction.z) * Mathf.Rad2Deg;
            transform.rotation = Quaternion.Euler(0f, targetAngle, 0f);

            controller.Move(moveSpeed * Time.deltaTime * direction);
        }
    }
}

[leaden ice]

do you have a joystick/gamepad plugged into your computer and leaning against something?

Also according to your code you are not using the PlayerInput component

if you have it attached, it's not doing anything at all

at least not anything related to this particular script

[real raft]

Turns out it was just my steering wheel, now it works fine. I thought it might have been related to some external device I had connected to my PC so I tried deleting the other input methods from the PlayerInput component but it still didn't work

Well it works now so it's not worth looking into it too much haha, thanks for the help

[leaden ice]

well again the PlayerInput component has nothing to do with your code here

you could remove it from your character and nothing will change

[real raft]

I generated a public C# class from the PlayerInput action I created and use public PlayerInputActions playerControls; to access it

[leaden ice]

yes indeed but that has nothing to do with the PlayerInput component

that's from your Input Actions Asset

(which you have named PlayerInputActions)

There's also a thing called the PlayerInput component which is unrelated

[real raft]

Oh, sorry I thought that was what I was using

[leaden ice]

this is the PlayerInput component

it's totally separate

You may be confusing yourself because you named your thing "Player Input Actions"

[real raft]

Yes I should be more careful with how I name things, thanks for clarifying

[earnest gazelle]

Why doesn't unity have a built-in behaviour trees but there is a package AI Planner (GOAP)?!

[rigid island]

because they thought it was more profitiable to add it to AI Muse

[heady iris]

huh, I didn't know about that package

[blazing tiger]

I got UnityWebRequest.Post with only a string data is obsolete. warn when sending posts to my server and apparently you're supposed to use MultipartFormSection now to send them?

Is there any actual benefit to using this thing? I thought simply JSONifying serializable data was OK

[vocal cypress]

Is there anything I can base my AI off of to get a more... real feeling?

Its for a FPS shooter and the human AI are very bland

[leaden ice]

MultiPartForm is for URL Encoded forms

[vocal cypress]

Ive tried adding states etc but it dosent help that much

[sudden stump]

AI is hard to program for a reason

Your best bet is to watch examples

[vocal cypress]

I can tell from experience

[leaden ice]

You want something like this:
https://docs.unity3d.com/Manual/UnityWebRequest-CreatingUploadHandlers.html
But with:

UnityWebRequest wr = new UnityWebRequest("https://www.mysite.com/data-upload", "POST");
UploadHandler uploader = new UploadHandlerRaw(Encoding.UTF8.GetBytes(jsonString));
uploader.contentType = "application/json";
wr.uploadHandler = uploader;```

[blazing tiger]

Yeah I got confused a little by the api. Already done the byte encoding thing 👍

But tnx

[sturdy cove]

guys does anyone have an idea why it doesn't want to discard

[limpid siren]

Hey guys, a question.
Im trying to create in code a renderTexture 80x80 and assign it to a camera i have already created in-game, and to a rawImage to be able to see what is in the camera in a Ui Image.
Is it possible to do that? or the renderTexture needs to be created in assets in order to work?

[lunar dirge]

So this is the code place cannons anywhere on the field, however, I can only place one and I can't place anymore. I ruled out it isn't an inventory issue because I have 5 of them but can only place one.

[delicate flax]

you never set 'defense' back to 'null' maybe?

don't know if you have other scripts interacting with this

but after the first run, this will start being true 'if (!inEdit || defense != null)'

[delicate flax]

given that 'defense' is a private variable, I'm 98% sure that's the issue

unless there is reflection magic going on

I really hope that's a troll, or that you are 12

[steep herald]

300 a year, I wish

You're a moron, I'll take my ban

[delicate flax]

@topaz charm I don't know the command to call in a mod / report... please assist, this is ridiculous

[heady iris]

nice, beat me to the mod ping

Vertx beat me to it again..

[quartz folio]

Just woke up and looked at the channel

[dawn nebula]

Imagine pirating Unity

[calm talon]

just use a personal license

[sturdy cove]

😭

[delicate flax]

run a manual 'git reset'? I don't know what UI tool that is

[sturdy cove]

Github Desktop

[delicate flax]

did you try running git reset from the cli? should remove all local changes

[sturdy cove]

ty , it fixed it self and i don't know why

did someone here use GIT LFS ? wanna ask him a Question
