I'm not even sure that would compile

You need to pass some parameter to the debug log method.

[regal basalt]

hello there, so another error occurred with the game, now the player flies among the camera orientation, can i send a short video of the movement?

[high cobalt]

like this?

would taht work?

[bright grail]

yep that would

does it?

[high cobalt]

I have no idea cause i have something spamming in the console

how does it not exist

[bright grail]

did you set a bool in the animator window for wall sliding

[high cobalt]

yes

do i delete that?

[bright grail]

no

[high cobalt]

i deleted it and it fixed it

[bright grail]

idk then maybe you 2 or something

[high cobalt]

okay, debug log now shows me it works but the roll itself does nothing

[bright grail]

does it "yes" get loged in console

[high cobalt]

yes;'

[bright grail]

ok so now you know its prolly something with the animation

[high cobalt]

just anim.SetTrigger for this?

or something else

[bright grail]

no you need to set one

[swift crag]

The parameter has to exist.

Did you actually create a Trigger parameter called "Roll"?

bool/float/int parameters do not count

[high cobalt]

Yeah I have one

[bright grail]

show us

[high cobalt]

like, in Unity?

[swift crag]

Show us the animator window with the parameter list visible.

[bright grail]

yea like a screen shot

[swift crag]

Ensure that there is not a space at the end of the name

Then show me the inspector for PlayerMovement.

[bright grail]

yo Fen i also have a rq question

[high cobalt]

this one?

[swift crag]

Oh, right, Animator is private and assigned in Awake

Make sure that the Animator on the same object uses the correct animator controller

Double clicking on the "Controller" field should open the Animator window

[high cobalt]

This is my Animator

[swift crag]

double click the "Controller" field and ensure that the animator window is still showing the same controller

[swift crag]

i.e. this one

[high cobalt]

yeah its showing

[teal viper]

Clear your console, make sure you are not in play mode and that there are no words in the console, take a screenshot of the console.

[high cobalt]

like, just an empty console?

wdym

[cosmic dagger]

The unity console where logs are displayed . . .

[teal viper]

If it's empty, then it's fine(assuming you don't have errors hidden)

[high cobalt]

Yeah I know?

yeah there are no errors

[teal viper]

If it's empty then start the play mode again and see if the warning appears.

[high cobalt]

when entering play

[teal viper]

Take a screenshot of the whole editor window

[high cobalt]

but it highlights another object

thats unrelated

had a deleted script in it

[cosmic dagger]

Was the name of that script changed or deleted?

[bright grail]

ok so rq before anything this code is just me testing and prototyping ideas, but baically the function run is to check if there is a tile next to this tile and if not the it returns null, in the if statments im checking if the return comes back null but and return a false if it does the timer max is set to 10, anyways im getting back a null error and idk if im just stupid or what so do you guys know why this is comng back as a null error and not a true or false?

[high cobalt]

I deleted the script but it was from an object i tried to do something with before

[bright grail]

sorry ik its a lot

[high cobalt]

which one's that 😅

[teal viper]

The unity editor. The whole thing.

[swift crag]

Which line is line 42?

[high cobalt]

The animation works now the thing that doesnt is the rolling mechanic

[swift crag]

Okay, so you are no longer getting the warning about the trigger not existing?

[teal viper]

[bright grail]

https://gdl.space/fagidepite.cs

[swift crag]

else if (GridManager.GetTileAtPosition(new Vector2(transform.position.x, transform.position.y+ 1)).tag == "Water")

Something in here is null.

I presume that GetTileAtPosition returned null

and then you tried to access the result's .tag member

[bright grail]

yep sorry i walked away for a sec

[bright grail]

here it is tho

and it changes based off of where the null tile is

it has to do with it not recognizing the null yk

[high cobalt]

this is the entiriety of my rolling code, is there something wrong with it? https://gdl.space/qusiseqaxi.cpp

it gives no velocity whatsoever

[swift crag]

If you attempt to access a member from a null reference, you get a null reference exception.

MyClass x = null;
x.foo = 1; // error
x.Bar(); // error

[high cobalt]

I put a debug.log into the part after private.void StartRoll() and it doesnt show up so maybe theres something wrong with that part?

[swift crag]

That sounds relevant, yes!

If the log message is the very first thing in the method, and the log message doesn't appear, then the method isn't being called at all

[bright grail]

but even if the function should be returning null

[swift crag]

I don't understand what you mean by that.

If the function returns null, and you try to access a member from the resulting null reference, you get an error

[bright grail]

wait i see what you mean

[high cobalt]

okay so actually it stops working at if (Input.GetAxisRaw("Roll") > 0), 1 line before it sends a message after it doesnt

[bold plover]

Will this hurt me long term or nah?

[bright grail]

im thinking i try for the null first then see if the tag is water

IM SO STUPID

[bold plover]

It fixes the error though I'm not sure why it happened to begin with.

[cosmic dagger]

What is AnimationTriggerType?

[swift crag]

I'm guessing you declared AnimationTriggerType as an enum inside of Player

using static lets you access things from a type without explicitly using its name (much like using lets you use stuff from a namespace)

[cosmic dagger]

Wait, so you have the same type (enum) in both of the Enemy and Player classes?

[swift crag]

If they're meant to be the same thing, then you should not be declaring them inside of other types.

you should declare the enum once

[high cobalt]

also would there be a way to change the collision while rolling?

[bold plover]

That's kind of the head scratcher as there is no reference to the Enemy in my Player script. That does answer my question though so thank you!

[swift crag]

as there is no reference to the Enemy in my Player script.

That has nothing to do with what I said

I think you need to show us your code here. You're probably doing something wrong here.

[bold plover]

gotcha

[high cobalt]

hey guys is something wrong with this lin e
(Input.GetAxisRaw("Roll") > 0)

[swift crag]

presumably you meant to put an if somewhere in here

[high cobalt]

oh yeah there's an if it didnt copy

if (Input.GetAxisRaw("Roll") > 0)

[wintry quarry]

Wrong in what way

[high cobalt]

the script doesnt work after that line

before all's alright

[wintry quarry]

define "doesn't work"?

[high cobalt]

doesn't run, debug.log doesnt show

[wintry quarry]

Is your console window open?

[high cobalt]

yes

[wintry quarry]

Do you have errors?

[high cobalt]

no

[wintry quarry]

You sure? What Debug.Log are you expecting to show?

[swift crag]

Code doesn't just "stop running" silently

[wintry quarry]

If the code after that line doesn't run that usually means you have an exception happening

for example maybe you didn't define an axis called "Roll"

that would show as an error in your console at runtime

Show the rest of the code and show your console window when the code runs

[swift crag]

Share the entire script.

[high cobalt]

https://gdl.space/igidalikas.cs

i removed the debug.logs already tho

[wintry quarry]

add them back

[high cobalt]

aight

[wintry quarry]

it's important to know which logs are not running as you expect

[swift crag]

Always show the code you were running

don't remove things

(especially don't try to "simplify" your code)

[high cobalt]

Okay I just got 2 errors after waiting

[wintry quarry]

those are not errors, they are warnings

[bold plover]

Apologies my code is a bit of a mess. 😔

[swift crag]

I don't see why it wouldn't be able to find the AnimationTriggerType enum. The enum is a nested type inside Player, and the function is also a member of Player

[high cobalt]

oh right, but still only things ive got

[wintry quarry]

what is this in reference to?

[swift crag]

Do you have another AnimationTriggerType defined somewhere else?

It sounds like you might have three of them

[wintry quarry]

Share the code with the logs back in

[high cobalt]

https://gdl.space/uvowacajij.cs
the code works up to line 116 (or at least thats what debug logs show)

[wintry quarry]

Then Input.GetAxisRaw("Roll") > 0 is simply not true

[swift crag]

the entire point of an if statement is to guard a block of code based on a condition, yes

[bold plover]

oml

THE TEST CUBE.

[wintry quarry]

Debug.Log($"Roll axis value is {Input.GetAxisRaw("Roll")}");```

[swift crag]

This has absolutely nothing to do with your problem

C# is unaware of what objects exist in your scenes

[tulip parrot]

Someone could help me with a problem with a terrain generation?

[high cobalt]

Doesn't show up

[wintry quarry]

where'd you put it lol

put it BEFORE the if statement obviously

[bold plover]

No I have a third script that applies that cube where I tested the code to begin with. It also has that AnimationTriggerType.

[swift crag]

If these are all meant to be the same enum, then you should declare it once.

[high cobalt]

Roll axis value = 0

[wintry quarry]

Mystery solved

[swift crag]

Right now, these are three completely unrelated types:

• Player.AnimationTriggerType
• Enemy.AnimationTriggerType
• AnimationTriggerType

They are not interchangeable.

[wintry quarry]

0 is NOT greater than 0

[high cobalt]

how can I fix that

[swift crag]

did you actually create an axis input called "Roll"?

[high cobalt]

Yea

[swift crag]

Where and how?

[wintry quarry]

presumably press the button that you assigned to that axis

[high cobalt]

the button is R and i press it doesnt work

[wintry quarry]

show your axis configuration

[high cobalt]

Input manager

[wintry quarry]

clearly not bound to the R key

[high cobalt]

removed it by accident rn

but it was

i was rolling to get to the debug logs no

pressing r

[wintry quarry]

fix it then show screenshot again

also wouldn't you jsut do GetButton("Roll") if all you want is a button?

[bold plover]

That makes more sense actually. Which is why I had to declare it as a static variable like you said.

Yeah I have 3 different ones. Test Cube wasn't at all related.

Thank you. Noob question it feels like.

[tidal remnant]

Quick question, instead of Navigation(Obsolete)
How should I reference Navigation?
Is it the same or have some values been replaced?

[swift crag]

i should point out that the component being attached to "Test Cube" doesn't matter here at all -- all that matters is that you wrote a C# script that declared an enum type named AnimationTriggerType

It sounds like you want to delete the AnimationTriggerType types from Player and Enemy, so that everyone can use the same enum type

[high cobalt]

i dont know

[bold plover]

Yeah I understand that now. Completely wrong assumption on my end. But I appreciate you reiterating so I don't misunderstand going forward in the future.

[wintry quarry]

I know. You would.

[high cobalt]

Man don't be so harsh on me I just started

[bold plover]

Almost took the wrong lesson from it. So again, thank you!

[wintry quarry]

Not being harsh

Just giving advice

[high cobalt]

Where do I place the GetButton

[wintry quarry]

instead of GetAxis

[high cobalt]

what do i do

[wintry quarry]

if (Input.GetButton("Roll"))

[high cobalt]

everything goes red after that

[wintry quarry]

you did some basic syntax error

¯_(ツ)_/¯

[verbal dome]

Input.GetButton

[wintry quarry]

oh my bad lmao

I'm not playing Baldur's Gate while I talk or anything

[high cobalt]

just like this, ya?

[swift crag]

oh, that Dragon Age ripoff? 🙄

and now i flee

[wintry quarry]

Yah

[high cobalt]

Okay it works after that line but still isnt propelling my character forward

debug log shows everything works but still it doesnt

[wintry quarry]

Well i mean you have like 8 different places in your script that are directly setting the velocity of the Rigidbody

Time to add more logs and see which of them is running and when

Seems like this would certainly do it:

        if (wallJumpCooldown > 0.2f)
        {
            body.velocity = new Vector2(horizontalInput * speed, body.velocity.y);```

I don't see how rolling could work when that code is running

[high cobalt]

I mean wall jump cooldown will be <0.2 no? so it wouldnt be running

cause you dont wall jump before rolling

or am i missing something here

oh shoot you were right it works without the code but when I delete it I can't movexd

[keen palm]

there are any way to make charactercontroller.SimpleMove to jump or i have to switch to .Move 🥺

[high cobalt]

what should I do to be able to move again im eepy slepy

[swift crag]

I don't believe so, since SimpleMove ignores the Y component

To switch from SimpleMove to Move, you need to make two changes:

• Add a negative number to characterController.velocity.y to calculate the new vertical velocity
• Instead of passing a velocity, pass a change in position. You can do this by multiplying your final velocity by deltaTime

float verticalVelocity = characterController.velocity.y + Physics.gravity.y * Time.deltaTime

This would do the trick.

[high cobalt]

what should I do with this line:
body.velocity = new Vector2(horizontalInput * speed, body.velocity.y);
it interferes with the rolling

what can I switch it out to

// Normal movement
if (wallJumpCooldown > 0.2f)
{
body.velocity new Vector2(horizontalInput * speed, body.velocity.y);

        if (Input.GetKeyDown(KeyCode.Space))
            Jump();
    }
    else
    {
        wallJumpCooldown += Time.deltaTime;
    }

this is the full

[swift crag]

perhaps you can stop setting the velocity during a roll

[high cobalt]

what should I do instead then

?\

[strange hazel]

hey yall so I'm working on moving a clicker game I made in Javascript to unity, and for once trying to organize the code. I'm new to unity though and I'm not sure how the best way to handle upgrades would be. I want to have a scrollable list of buttons to buy upgrades with a simple function like buyUpgr(tier), but how would I go about making the upgrades in a succinct way, I don't need separate objects for the upgrades I don't think, I just need a way to store the price, name, tier, and amount. this should be simple but I have no idea and have been stumped lol

[keen palm]

thanks you save my life

[strange hazel]

in Javascript I literally just had an endless list of integers for prices and how much the player had and it worked but it was so clunky for no reason

[swift crag]

Are you going to manually define all of those values?

Rather than using a formula to calculate them

[strange hazel]

well once you buy the upgrade, it's gonna be formulaic for the next price as part of the function

but all the starting values would be manual, unless there's an easier way

[swift crag]

Will all upgrades use the same sort of formula?

e.g. they all double in cost for each tier

[strange hazel]

no so I could probably also store the multipliers they use

but it would be a simple multiplier

like some being 1.7, some being 1.5

[swift crag]

As long as you aren't using totally different formulas for different upgrades, then it'll be pretty simple

So, I'd suggest creating a class like this:

[System.Serializable]
public class Upgrade {
  public string name;
  public float baseCost;
  public float costGrowthMultiplier;

  public int level;

  public float CurrentCost => Mathf.Pow(costGrowthMultiplier, level) * baseCost;
}

you can now create a List<Upgrade>

CurrentCost is a property, so it gets calculated each time you use it

[strange hazel]

oooh alright, and then just how would I go about getting and setting data from that, just make a new() and do that[tier].price?

[swift crag]

You wouldn't create any new Upgrade instances at runtime

you'd just set this up in the inspector

How are you going to actually use this upgrade data, though?

Right now, this is just a list of "upgrade" objects, each of which has a:

• name
• level
• cost to upgrade

[strange hazel]

whenever i click one of the assorted buttons in the upgrade shop, i would want to run a function like buyUpgr(tier of upgrade)

[swift crag]

Who else is going to use this upgrade data?

I imagine it's not solely used by the upgrade button

[strange hazel]

cuz like in Javascript how I had it as buyUpgr(0-whatever for index) I figured it would be the same

[swift crag]

other parts of your game care about the upgrades too

[strange hazel]

the upgrade buttons, the prices and amounts are showed on the upgrade buttons

[swift crag]

right, but you use these upgrades somewhere else, right?

[strange hazel]

but other than that I'm not sure off the top of my head, more just trying to plan for the future

[strange hazel]

the upgrades themselves are gonna be handled through varying timed functions in the game manager

[swift crag]

An issue with this design is that you can't easily reference the upgrades in the inspector. They're just plain old objects.

You can't drag them into fields in the inspector

But you could adapt it a little.

For example, you could create a Dictionary<string, Upgrade> that's stored in the game manager

When the game starts, you do this:

[radiant frigate]

does someone know why the math doesnt activate?

[swift crag]

Dictionary<string, Upgrade> upgradeMap = new();
[SerializeField] List<Upgrade> upgradeDefinitions;

void Awake() {
  foreach (var upgrade in upgradeDefinitions) {
    upgradeMap[upgrade.name] = upgrade;
  }
}

public Upgrade GetUpgrade(string name) {
  return upgradeMap[name];
}

This would be in your "Game manager" class

An upgrade button could store the name of the upgrade it's for

It can then ask the game manager for the Upgrade

[strange hazel]

alright I think I've got it now

[swift crag]

The only problem here is that you could use the wrong name

e.g. you could have a typo

[polar acorn]

Well, when you subtract 0 from 10, what are you expecting to get?

[radiant frigate]

i just saw that damage was not set to any number 😭

[radiant frigate]

ty man you saved me like probably an hour searching

[regal basalt]

i need help with my player movement, it doesn't recognise the keys, and i'd like to know why is that happening and how am i suppost to fix the error (i've set comments in the lines with an error to help identify)

i've only sent the base movement block

i will break it down for you

before i send the code, these are the 3 errors i kept getting

[rich adder]

you gotta use the link.

[regal basalt]

how so?

collab?

[rich adder]

what?

[rich adder]

did you read what they sent you .

sending only a snippet when showing null references we can't see lines accurate anyway.

[regal basalt]

https://gdl.space/iramemutob.coffeescript

im new to this mb

[rich adder]

well you would ideally send the whole class as is..

whatever is on line 145,294, 390 is null

[regal basalt]

i didn't get it

let me get this straight

are you asking for the complete code?

the 700 lines?

[rich adder]

thats what the websites are for

so you can send whatever size they are

your error seems to be NRE anyway
(Null Reference Exception)
https://unity.huh.how/runtime-exceptions/nullreferenceexception
check the Troubleshooting

[cosmic dagger]

Not sure why you have both classes in the same script each class should have their own (script) . . .

[regal basalt]

https://gdl.space/macuripeli.cs

[rich adder]

ok you don't have to add the `` cs`thats all only for chat

and yes why is an editor script in another script..

anyway looks like you got multiple things that are null so fix it

indeed

doesn't look like crosshairObject was found on whatever object has that script FirstPersonController

and sprintBar, sprintBarCG

this code also handling UI

[regal basalt]

wdym by that?

its messy and bad practice to mix UI code with something that should be controlling your character controls

but its code beginner so you are forgiven 🙂

from now on i am doing a script for every single function

"every"

[rich adder]

not every fuction, that would be insanity

ideally for every " purpose "

[regal basalt]

that's one word for it yes

i'd call it intention, but

your fits better

at least you don't say "Teams only supports files up to 250Gb" 🤓

[regal basalt]

one's gone

how so?

[regal basalt]

@summer stump

[summer stump]

Don't do that.

But because it is wrong

There is a reason it is the single most quoted and followed principle in software engineering

[regal basalt]

as a joke?

[summer stump]

Do you mean the singleton referencing other things, or other things referencing the singleton?

Start is generally used for external references, awake for self-reference
The issue that can pop up is when using it in DDOL, when awake and start will not be called when a new scene is loaded

[rich adder]

assign singleton instance in awake while everything else should at least wait Start to use instance of it , yes

[regal basalt]

@random dirge when you have a singleton with serialized fields, they are typically used to hold references to other objects in the scene

[summer stump]

As said twice, use start
Awake only for self-reference

[summer stump]

Like getting a component reference to the same object as the singleton, or initializing values. Never for getting a reference to a different object or values in a different script

Even that is not foolproof though, but it is a start

[cosmic dagger]

Awake is used for (inside) self-initialization. Start is used for outside initialization . . .

[summer stump]

Where is that from?

[rich adder]

not accounting for a singleton

[cosmic dagger]

Because Start is called only once when the script is first enabled (which is when a GameObject first becomes active) . . .

[summer stump]

Weird. Well, getting a reference to a SCRIPT could be fine in awake. Not to a value IN the script though

[slender nymph]

those commends also do not contradict what was told to you

[cosmic dagger]

They mean references between scripts (on the same GameObject). They just weren't specific . . .

You reference scripts from other (outside) GameObjects in Start . . .

[fallen ember]

What's the point of awake if you can reference scripts in the same gameobject on start

[summer stump]

Then things may not be initialized when you try to reference them from the start of another script

[rich adder]

not just for null too, imagine this scenario

//script1
void Awake()
{
    number = INeedSomeValue();//9
}
//script2
void Awake()
{
    Debug.Log(script1.number);//logs 0 or whatever initialized field was
}
void Start()
{
    Debug.Log(script1.number);//logs 9
}```

[summer stump]

It gives you two different times. The first start (of objects existing when the scene is loaded) is guarenteed to be after all awakes

[fallen ember]

ahh got it

[summer stump]

Instantiating obviously doesn't work that way though

[magic panther]

I have this part in my update function inside my player, and though I press the keybind it seems to do nothing (fullscreen is a public bool). Is this just me not knowing at all how to use Screen stuff?

        if (Input.GetKeyDown(fullscreenKey)) {
            fullscreen = !fullscreen;
            Screen.fullScreen = fullscreen;
        }

[slender nymph]

are you testing in a build? because the editor will not play game mode in actual fullscreen

[magic panther]

yes, testing. Is there a way to see this in action while testing?

I mean not test build, testing the game as in during development of it

is there a game file I should launch via file explorer?

[slender nymph]

put a log there to print when it does its thing and what it changes to

otherwise build it

[magic panther]

whenever I press the keybind it switches on or off (not while holding)

which is the desired behavior

[regal basalt]

it's working now, thanks for the help

@slender nymph sry to bother again but i basically replaced Vector2.up with transform.up like you told me and it doesnt really seem to work

i mean like it wont even add the force to begin with so i cant really tell which direction its facing

[slender nymph]

have you made any other changes to the code? also you can select the object in the hierarchy and set the tool handle to Local instead of Global to see the direction its axes are facing

[wanton otter]

pretty much the only change i did to the code

gimme a sec

like this?

[slender nymph]

the upper left buttons in your scene view window are the tool handle buttons. your rotation one (the second one) needs to be set to Local

[wanton otter]

how can i set it to local 😅

[slender nymph]

i just told you how

[wanton otter]

1 second

[slender nymph]

there you go. so as long as the component with the code you showed is actually attached to that object it will add force in the correct direction

[wanton otter]

nice but it still wont apply the force for some reason

[slender nymph]

was it adding the force previously

[wanton otter]

yea

[slender nymph]

then what else did you change

[wanton otter]

i didnt change anything

i can double check that it applied the foce previously

gimme a sec

[slender nymph]

you had to have changed something if it was working before and it isn't now

[wanton otter]

my bad ive accidentally changed the type of force to vector instead of float

it probably works now ill give it a quick check

ayy works like a charm

thx again 🙂

its a bit weaker now that its angeled though

even turning up the force still mostly pushes the character up rather than to the right

[slender nymph]

that's likely due to how you move the player

[wanton otter]

is it possible for me to screenshare to you?

[slender nymph]

no. you can share your code and send a screen recording or screenshots here though

[wanton otter]

good enough, give me a second

[spice breach]

I'm currently trying to improve a maze generator I made by giving it the ability to generate multiple floors on the same maze

my idea is is to mark the exit/goal node of the previous level as the starting node for the current level, by removing the floor

Am I able to use a 2D array to store all the nodes in the mazes, 1 storing the number of that node, relative to its level

this may sound like absolute waffle but i feel like it'll be easier in my head if i say it

stupidest question ever, yes i can

[spice breach]

how would I go about assigning an entire row to a list, from this 2D array?

[rich adder]

int rowIndex = //pick a row
int numberOfColumns = levels
for (int col = 0; col < numberOfColumns; col++)
{
    currentFloorNodes.Add(nodes[rowIndex, col]);
}```

[spice breach]

I could use a for loop

ah

yeah

cheers my friend

I've seen you talk here quite a lot, you are a life saver for a lot of people my brother 💙

[modest dust]

Or use a jagged array and pass the intire row into the list

[rich adder]

when I get a chance lol

true, directly access the whole row is good

[dry spruce]

can any one help me on this

[timber comet]

Did you check, if you have the package for TextMeshPro?

Try creating one first (I mean, try adding in your scene a TextMeshPro text in the editor)

It should prompt you to import the package

[dry spruce]

thanks for your help

got it?

[timber comet]

Yes

I’m trying to find the error

[dry spruce]

ohk

[timber comet]

Ok so

The error is trying to tell you that in line: 3 you have a

Which doesn’t exist

You need to remove that line

[cosmic dagger]

line 3 is using System.Diagnostics.Contracts;. does this exist? if not, remove it . . .

[dry spruce]

ohk

new error

i want to build n run

[languid spire]

Not a code problem. #🥽┃virtual-reality

[dry spruce]

no one is responding there

[languid spire]

Then wait

[languid spire]

screenshot the complete console window

[sly lake]

naah, it was not mine

I just show the error

[languid spire]

lol, the error is actually in the line you cropped out

[dreamy dune]

maybe dumb question but why do some people use namespace in their scripts

[languid spire]

really you should always use namespaces. It allows for the allocation of scripts into logical secctions

[dreamy dune]

so its easier to find?

[lean sedge]

I been trying to access and modify a mesh on a gameobject through a scriptable object. But I'm a bit confused, do I pass a mesh to a meshfilter to change the form of the object?

I've declared a mesh variable on my scriptable object and picked the capsule mesh. Then I declared a mesh on my object I want to change the mesh of. But on that I get a type mismatch. I can't select the gameobject in the inspector.

[eager spindle]

you mean to change the mesh? yes, the meshfilter contains the Mesh to be rendered. so you can meshFilter.mesh

[eager spindle]

on your scriptableobject you cant really reference a meshfilter because the meshfilter is a reference in the scene, switching scenes will break it

[lean sedge]

So I can not modify my gameobjects mesh with a scriptable object?

[eager spindle]

youll need to test it tbh

try referencing the meshfilter first and see if anything bad happens

im not sure if the SO will allow you to reference a scene variable

[lean sedge]

I can reference a meshfilter to my scriptable object but it results in a type mismatch in the inspector

So I cant really do anything with it

[river quiver]

how do i change color of the text by script?

price.color = new Color(15, 30, 247, 255);```

this doesnt work for me

[keen dew]

Color values are between 0 and 1. If you want 0-255 use Color32 instead

[river quiver]

aaa okay

[river quiver]

ty

works

[dreamy dune]

i am making a inventory system is it reliable to use a system where it has a databse based on names

[modest dust]

Based on names for what? Looking them up in the database?

There can technically be duplicate names

It's better to give a unique id to each item instead

[languid spire]

Also, should you want to implement language localization using any string descriptor would break your database

[dreamy dune]

is it possible to change your project to urp ?

[modest dust]

https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@7.1/manual/InstallURPIntoAProject.html

[mild mortar]

So I have a base class for AI general stuff that sort of looks like this

public class Hostile : MonoBehaviour, IDamageable, ITriggerCheckable
{
    [field: SerializeField]
    public float maxHealth { get; set; }
    [field: SerializeField]
    public float currentHealth { get; set; }
    [field: SerializeField]
    public bool IsAggroed { get; set; }
    public bool IsWithinAttackRange { get; set; }

    [HideInInspector]
    public Navigation navigation;
    [HideInInspector]
    public LineOfSight lineOfSight;
    public GameObject target { get; set; }

    #region State Machine Variables
    public EnemyStateMachine stateMachine { get; set; }
    public EnemyIdleState idleState { get; set; }
    public EnemyChaseState chaseState { get; set; }
    public EnemyAttackState attackState { get; set; }
    #endregion

    void Awake()
    {
        stateMachine = new EnemyStateMachine();
        idleState = new EnemyIdleState(this, stateMachine);
        chaseState = new EnemyChaseState(this, stateMachine);
        attackState = new EnemyAttackState(this, stateMachine);
        navigation = GetComponent<Navigation>();
        lineOfSight = GetComponent<LineOfSight>();
        stateMachine.Initialize(idleState);
    }

I want different types of course, so 've made a class called Zombie that inherits from Hostile. I want Zombie to set the sightRange of the lineOfSight component to 15.

But it keeps telling me it has a null reference for the object.

I assume it's because the child is trying to call before the parent sets up properly. Anyone know how to generally fix this?

[modest dust]

Where does your assumption come from?
When does the subclass of the Hostile class tries to use the lineOfSight component?

[hexed terrace]

your awake needs to be a virtual method

[modest dust]

If it's in awake then just as Carwash said ^

virtual, override, call base and then do your stuff

[hexed terrace]

protected void virtual Awake() { }

and then in your Zombie class, override it

protected void override Awake() 
{ 
  base.Awake(); 
  // other code
}```

[mild mortar]

Oh okay, thanks a ton guys!

[mild mortar]

In regards to this, my zombie class is just adjusting lineOfSight.distance within it's own awake

[modest dust]

Yeah, then do as Carwash said

[mild mortar]

So just something as simple as this?

public class Zombie : Hostile
{
    private float sightRange = 15;
    protected override void Awake()
    {
        if (lineOfSight != null)
        {
            lineOfSight.distance = sightRange;
        }
    }
}```

Gonna remove the if check now

[languid spire]

you missed the base.Awake()

[modest dust]

You forgot the base call

[mild mortar]

Oh right yeah

My bad

protected override void Awake()
    {
        base.Awake();
        lineOfSight.distance = sightRange;
    }

Like this?

[modest dust]

Try it out

[mild mortar]

No luck
"Zombie.cs(10,29): error CS0115: 'Zombie.Awake()': no suitable method found to override"

distance within lineOfSight is just a getter/setter if that matters

[languid spire]

then you 'forgot' some thing else
protected void virtual Awake() { }

[modest dust]

Show your Hostile class, the Awake method needs to be marked as virtual

[mild mortar]

protected virtual void Awake()
    {
        stateMachine = new EnemyStateMachine();
        idleState = new EnemyIdleState(this, stateMachine);
        chaseState = new EnemyChaseState(this, stateMachine);
        attackState = new EnemyAttackState(this, stateMachine);
        navigation = GetComponent<Navigation>();
        lineOfSight = GetComponent<LineOfSight>();
        stateMachine.Initialize(idleState);
    }

Huh, just hit play again, it works now.
No worries then

Guess it didn't update the file properly

Thanks again guys

Hmm, actually, there's something I'm still missing somewhere I think
Doesn't seem as though that distance is changing on play.
The vision cone remains the same even though I am overring 🤔

{
    private VoxelData voxelData;

    private void Start()

    {    
                    VoxelCell cell = voxelData.GetCell(x + chunkCoord.x * chunkWidth, y, z + chunkCoord.y * chunkDepth);```  my voxelData.GetCell is giving me a null reference. im getting the voxelData from my manager instance, can i not use .GetCell on it from this script or is there something else going wrong?

i got the debug.log that it is not null

[modest dust]

When do you call GenerateVoxelMesh()

[safe radish]

on the start of my chunkmanager script private void Start() { RandomOffset(); voxelData = GeneratePerlinNoiseVoxelData(); GenerateChunks(); initialized = true; }

its in the generate chunks method

[modest dust]

Then show the GenerateChunk() method instead.

[safe radish]

    {
        ClearChunks();

        int chunksX = gridSize.x / chunkWidth;
        int chunksZ = gridSize.z / chunkDepth;

        chunks = new NewChunk[chunksX, chunksZ];

        for (int x = 0; x < chunksX; x++)
        {
            for (int z = 0; z < chunksZ; z++)
            {
                Vector2Int coord = new Vector2Int(x, z);
                GameObject newChunkObj = new GameObject("Chunk_" + x + "_" + z);
                newChunkObj.transform.parent = this.transform;

                NewChunk newChunk = newChunkObj.AddComponent<NewChunk>();
                newChunk.Initialize(coord);
                newChunk.GenerateVoxelMesh();
                newChunk.UpdateMesh();

                chunks[x, z] = newChunk;
            }
        }
    }```

[modest dust]

Just replace Start() with Awake()

In the NewChunk class

[safe radish]

that fixed it, ty

[modest dust]

But it wouldn't be a bad idea to just pass the voxel data in the GenerateVoxelMesh() method

Instead of getting it through a static instance in Start/Awake

[mild mortar]

Anyone know how to get rid of this error?

I thought restarting Unity would do it, but it just never leaves

[verbal dome]

Some graph window is bugging out a bit, could be Shader Graph, VFX Graph or Animator window for example

Can try to reset your layout and see if it helps

[mild mortar]

Hmm, gave it a try but unfortunately still there

No way to set an ignore for that particular error I imagine?

[verbal dome]

Did you clear the console though?

[mild mortar]

I did yeah

[verbal dome]

What is your unity version?

[gilded kiln]

Okay guys i have a big problem, my unity wont launch

Yesterday it worked

I have no idea for what it doesn't work today

I must work rn but I can't omg

[eager spindle]

well we dont know why your unity isnt launching either

got a screenshot?

@gilded kiln

usual tech questions: have you tried restarting your pc, reinstalling unity, did you do any funky stuff with your project files?

[gilded kiln]

Actually i dont want to reinstalling Unity, i already try to restarting obviously it doesn't worked but now I'm try to earased all files in the folder Temp

No I do nothing wrong with Unity

[eager spindle]

do you have a screenshot of what happens when you try to boot up unity

[gilded kiln]

Nothing happens that the problem

[eager spindle]

unity hub or unity editor?

[gilded kiln]

And I think I can't take a screenshot of nothing lmao

[gilded kiln]

Unity Hub

[eager spindle]

uninstalling hub shouldnt remove editor

[gilded kiln]

I know how to start Unity I do it a lot of time

[eager spindle]

plus you might be able to start editor without hub

[gilded kiln]

Normally I need to start Hub before the editor

[eager spindle]

C:\Program Files\Unity\Hub\Editor\2022.3.19f1\Editor
this brings me here, theres a unity.exe you can use

change the version accordingly

dumb plan but yeah

secondary plan is to find out directly whats wrong with unity hub by launching unity hub from a command line

but theres a point where you just reinstall unity hub

on a differrent note is unity hub installed on a different drive?

[gilded kiln]

I'm trying

No it's not working

Nothing work

OMG i think i will reinstall

LMAO

The first worked but the second not

[late burrow]

my class has implicit string conversion, why cant i string.join it?

[late burrow]

i dont seem be able write conversion for class array only for class

[slate haven]

I have written a code for facing the player in the direction it moves, but it behaves very weirdly and causing the player to move in unwanted directions. Please help!

    {
        PlayerControls();
       
    }

    void PlayerControls()
    {
        float xInput = Input.GetAxis("Vertical") * moveSpeed * Time.deltaTime;
        float yInput = Input.GetAxis("Horizontal") * moveSpeed * Time.deltaTime;
        playerTransform.Translate(xInput, 0, -yInput);
        


        //for rotation
        Vector3 direction = new Vector3(xInput, 0, -yInput);
        playerTransform.forward = Vector3.Slerp(playerTransform.forward, direction, Time.deltaTime);
        
    }```

[amber nimbus]

Hello, I was wondering, where should I declare interafaces. For example if I have an IDamageable interface I would use it in my Enemies script, my Players script and any items that could be damagable. Do I declare it in one of the objects scripts? Should I have one big script for just declaring different interfaces?

[slate haven]

make a different script an interface which has all the damagable logic, and then attach that interface to all items

[cosmic dagger]

Just make a script, name it your interface, and define it in the script . . .

All of your types should be in their own script . . .

[slate haven]

is the code logically correct or its not?

[amber nimbus]

So each new interface I make should have a different script?

[slate haven]

yes for every different interface

[amber nimbus]

x axis is horizontal from what I know

[cosmic dagger]

Yes, an interface is a type. Just like a class, struct, ScriptableObject, interface, etc. . . .

[slate haven]

yes but i set it because my camera is set up like that

if u can imagine that

[timber comet]

Can this help you?
https://docs.unity3d.com/ScriptReference/Transform.LookAt.html

[slate haven]

it just made the player start rotating around an axis

not face the direction it moves

[amber nimbus]

Your direction Vector is just the players transform.position + input, a direction needs to be calculated as some target.position - transform.position

[late burrow]

why cant i write operator for class array error says i must convert from exact type and its array fails to count as one

[summer stump]

Unity has a page for that
https://docs.unity3d.com/2018.3/Documentation/Manual/DirectionDistanceFromOneObjectToAnother.html

[safe radish]

    {
        ClearChunks();        
        chunks = new NewChunk[numberOfChunksX, numberOfChunksZ];

        for (int x = 0; x < numberOfChunksX; x++)
        {
            for (int z = 0; z < numberOfChunksZ; z++)
            {
                Vector2Int coord = new Vector2Int(x, z);
                GameObject newChunkObj = Instantiate(chunkPrefab);
                newChunkObj.name = "Chunk_" + x + "_" + z;
                newChunkObj.transform.parent = this.transform;    //< This line gives the error

                NewChunk newChunk = newChunkObj.GetComponent<NewChunk>();
                if (newChunk == null)
                {
                    newChunk = newChunkObj.AddComponent<NewChunk>();
                }

                Vector3 chunkPosition = new Vector3(coord.x * chunkWidth * scale, 0f, coord.y * chunkDepth * scale);
                newChunkObj.transform.position = chunkPosition;

                newChunk.Initialize(coord);
                newChunk.GenerateVoxelMesh();
                newChunk.UpdateMesh();

                chunks[x, z] = newChunk;
            }
        }
    }```  im getting these warnings but no errors

[slate haven]

what shall be the target position here?

[amber nimbus]

I cant really imagine what your game looks like given that your horizontal and vertical axis are switched but you could try subtracting your players position from the input Vector3 you have already made

[slate haven]

whats different between this code and mine

like in this it didnt subtract the target and transform position

[slate haven]

because this code works but mine doesnt

[amber nimbus]

Oh yes, you could do it this way, but you cant use your xInput and yInput variables, they are multiplied by your speed and Time.deltaTime

[polar acorn]

You know if you're going to continue to refuse to provide enough context for anyone to have any goddamn clue what you're asking about you can probably just cut the middleman and not ask

[slate haven]

ohh, got it

[slate haven]

but what if I normalize it?

like direction.normalize

[late burrow]

    {
        public static implicit operator string(test[] thing)
        {
            return "";
        }
    }```

cant use array

[polar acorn]

So you're trying to cast an array of test to a string? That's not going to work. You can't implicit something that isn't this type

test is not test[]

[late burrow]

well idk whats difference can use explicit as well

i just want convert it to string without additional functions

[polar acorn]

why

[late burrow]

because messy

[polar acorn]

What's the problem with public string SomeFunction()

[polar acorn]

Get over it

This is unfathomably more messy

than just having a function that returns a string

[late burrow]

having 20 functions for conversions is not cool and when i found out about implicit its amazing

just it dont work for arrays for some reason

even chatgpt says it supposed to work

[amber nimbus]

I do not think it would work, normalizing changes the length of a vector, not it's direction

[languid spire]

oh, well if gpt say so it must be wrong

[polar acorn]

I mean, a hammer is an amazing tool until you discover that screws exist

[slate haven]

ohh

[polar acorn]

Because test is not test[]

[late burrow]

and i cant define class of test[] either

[polar acorn]

because it literally does not know anything whatsoever

[polar acorn]

correct

[late burrow]

i cant literally do anything with arrays

[polar acorn]

so stop trying to use implicit here

It's a bad plan to make bad code for no reason

[slate haven]

    {
        float zInput = Input.GetAxis("Vertical") * moveSpeed * Time.deltaTime;
        float xInput = Input.GetAxis("Horizontal") * moveSpeed * Time.deltaTime;
        playerTransform.Translate(xInput, 0, zInput);
        


        //for rotation
        Vector3 direction = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
        playerTransform.forward = Vector3.Slerp(playerTransform.forward, direction.normalized, Time.deltaTime * 10f);
        
    }

I did this, now the player looks in the direction I move, but now my movement is messed up, like it wont move in the same direction when I added the rotation logic

[slate haven]

brother there will be a day when u will start having trust issues with AI, soon

[late burrow]

well it wrote entire server for webpage for me so

[amber nimbus]

Well yes, you changed -yInput to zInput

[slate haven]

I fixed my camera so thats why

[polar acorn]

No, it stole a server webpage from a stack overflow question you could easily have googled yourself

[slate haven]

try to build a full fledged working game with it and u will know its suffering

Vector3 direction = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
I did input the actual values without multiplying speed but still the same problem

[amber nimbus]

It wont move in the same direction as in it is going the complete opposite way correct?

Beacuse I think in your zInput you forgot the negative sign

[slate haven]

not opposite, i think its mixing the rotation with movement

its like combining the rotation with movement

so If I press W for instance, it starts revolving or some shit

[amber nimbus]

https://docs.unity3d.com/ScriptReference/Transform.Translate.html you should read the description of Transform.Translate here

[slate haven]

Reference

[slate haven]

okay

[amber nimbus]

The transforms are applied in local space, this means that they are affected by your players rotation

Which means that as your player rotates it tries to go forwards, where the player rotated

[slate haven]

yes

so what do i do?

[amber nimbus]

you need to set the relativeTo parameter (which is optional) to world

It is written in the documentation I showed you above

[slate haven]

wouldnt that make my approach much more complex?

than it shall be

[slate haven]

i will read it

[polar acorn]

So, basically, here's the not stupid way to do this:

public class test
{
  public static string ArrayToString(test[] thing){
    return string.Join(",", thing);
  }
}

Stop trying to use your fancy new hammer on every fixture in the house. Sometimes, you're gonna need a screwdriver

[late burrow]

bruh i tried to use string.join in the first place and its not able convert it to string

that why i wanted implicit cast

[amber nimbus]

If you dont want to mess around with local and world space, transform.position is always in world space, meaning you can also replace playerTransform.Translate(xInput, 0, zInput) with playerTransform.postion += new Vector3(xInput, 0, zInput)

[polar acorn]

I figured since you were so gung-ho about implicits you already had an implicit for test to string

If not, then you can use Linq to map ToString over it

[late burrow]

i do have it

and string join still fails to convert

[polar acorn]

What is the exact error

[slate haven]

ohh

[amber nimbus]

Also when developing a 3D game understading world and local space is very important

[late burrow]

ambiguous call

[slate haven]

okay got it

thanks!

[late burrow]

i can type its class but then it just prints class name without actual data

[summer stump]

That is not the "exact" error

[slate haven]

ig i will have to read up some documentation

[late burrow]

The call is ambiguous between the following methods or properties: 'string.Join(string, params object[])' and 'string.Join<T>(string, IEnumerable<T>)'

[summer stump]

Ok, perfect. So it IS able to, you just made a mistake. Show exactly what you wrote

[polar acorn]

This fully compiles and does exactly what you expect it to

It's unsure if you want to pass in the list as a list or as params, so it's ambiguous

you don't need implicits at all

You just need to tell it "No this is supposed to be a completed list, not params"

See how easy it is to fix when you actually give us the fucking information as to what you are doing

[late burrow]

noone mentioned object array conversion till now

[polar acorn]

because you haven't actually told anyone what your error was for three months

Turns out this whole time it was a stupidly simple solution and you just kept stepping on rakes because you assumed we "didn't need to know what you were trying to do" to help

well fuckin look at that, turns out once we did get it it was an easy problem

[late burrow]

i havent touched arrays till now implicit cast for type is still useful

just arrays were issuing

[polar acorn]

sure, implicits are useful. However, you never needed them to solve this problem and going down that rabbit hole just kept moving you further and further from actually solving the problem

[late burrow]

though i see object[] cast still doesnt solve issue

[polar acorn]

Okay, what doesn't it do that you expect it to do

[late burrow]

its logs as script+test

still not loggingg data just the type name

[polar acorn]

Does your test class have a ToString?

[late burrow]

no

[polar acorn]

The default ToString of every object is just their name

[late burrow]

why doesnt it use implicit

[polar acorn]

so if you want it to do something different, you have to have told it to do that

[polar acorn]

because that's not what implicits are for

Every object has ToString. That is, in fact, one of the only things that can be said of the type object. That's just about the only shared function on it

So you've been spiraling into madness when the solution was ToString and casting to object. Something that basically anyone on this server could have answered in five minutes if you had actually said what you were trying to do from the beginning

[olive lintel]

hey guys, pretty embarrassing but for some reason visual studio doesn't seem to reference exceptions? I'm not quite sure whats going on. I put "NullReferenceException" in the catch statement and it doesn't even seem to recognise the syntax for it. Does anyone know what I'm doing wrong here?

[swift crag]

What is the error?

[languid spire]

missing a using System ?

[olive lintel]

this, I'm pretty confused

[olive lintel]

using UnityEngine

oh wait

wow

[swift crag]

That is not an exception being thrown.

[olive lintel]

thats embarassing

[languid spire]

for Exception? NO

[swift crag]

At least, it doesn't have to be one.

You can write an error to the console with Debug.LogError.

[olive lintel]

😬 yikes my fault

[olive lintel]

yea idk the correct way to phrase it my fault

thanks guys that was confusing me for a while 😭

[swift crag]

Figure out where the NaN is coming from when calculating the force.

[west flax]

@swift crag

Omg I forgot to commit the new changes

[swift crag]

is there a reason you're editing this on your phone...?

[west flax]

I don't have discord on my laptop

[olive lintel]

see the weird thing is I did a check to see if the wheel.thrust or wheel.thrustpower == float.NaN and it isn't

which has me super confused

[west flax]

Under axis.Normalize(), I added axis*=Math.Deg2Rad;

[swift crag]

perhaps the wheel has already gone to space, so that transform.forward is full of NaNs

[swift crag]

axis?

you convert the angle, not the axis..

[west flax]

Oh my god lmfao

That's funny as hell

I'm an idiot xD

[swift crag]

That will slow you down

you should ask about the problem code first next time :p

[west flax]

I wasn't thinking about how it interacted with the code, just the results.

That's why I was confused.

[olive lintel]

all of these checks yet alas, the issue persists :/

[swift crag]

Just log all of the values.

Importantly, I don't think float.NaN compares equal to anything

You'd have to use float.isNaN()

[west flax]

Are you multiplying by excessively high numbers?

[olive lintel]

ahh I see

it was the wheel.thrust value

I'm not quite sure what is making it NaN I think the engine simulation thingy needs a frame at the start

it accounts for the velocity of the previous frame etc etc

I see now

thank you very much

[hushed hinge]

I have a problem that when I pause the game to change the volume by using the slider in unity, when I turn down the volume, and after I unpause to resume the game, the volume changes bak to full when I move the player to the right, and the volume turns down when I move the player to the left, by using the "a" button for moving left and the "d" button for moving right, that only happens when I pause the game to change the volume, how do I fix that so the volume doesn't change when I move the player?
this is the volume setting
https://gdl.space/ahujifaced.cs

and the pause script

https://gdl.space/delixivuze.cs

[slender nymph]

your slider is still selected by the EventSystem because you aren't setting the canvas's GameObject inactive, you just disable the canvas component. so either set the currently selected gameobject to null in the EventSystem or completely disable the object(s)

[mild mortar]

Am I blind? Unity is giving me this error:
error CS0122: 'State.lineOfSight' is inaccessible due to its protection level

It's inheriting a protected so it should have access right?

public class State : MonoBehaviour
{
    public LineOfSight lineOfSight;
    private void Awake()
    {
        lineOfSight = GetComponent<LineOfSight>();
    }
    public virtual State Tick(StateManager stateManager)
    {
        return this;
    }
}

public class IdleState : State
{
    PursueState pursueState;
    [Header("Detection Layer")]
    public bool hasTarget;

    private void Awake()
    {
        pursueState = GetComponent<PursueState>();
    }
    public override State Tick(StateManager stateManager)
    {
        if (lineOfSight.objects.Count > 0)
        {
            return pursueState;
        }
        else
        {
            return this;
        }
    }
}```

[slender nymph]

have you saved the State class

[hushed hinge]

change something in the eventsystem in the first image, or but the null in the second image?

[sharp abyss]

I'm making a 2d football game. When characters hit the ball it never goes up when its on the ground what can I do about that?

[slender nymph]

neither, my suggestions were both code related so you aren't changing any settings on the EventSystem component. you need to tell the EventSystem component that nothing is selected when you exit your pause menu. and simply assigning null to a field is completely irrelevant to what i've said

[mild mortar]

Yeah it's been saved

[languid spire]

then where do you see protected in your code?

[mild mortar]

Okay, I restarted Unity twice and now it works all of a sudden
First restart still had the problem

[hushed hinge]

like this?

[mild onyx]

what am i doing wrong here? im trying to click the text and have it take me to another scene (the game)

[swift crag]

add a Debug.Log statement to find out if the function is being called at all

[mild onyx]

from what ive seen its not acting like a button at all, my curser doesnt change when i hover over it and the colours dont change, neither of which are even in the code

[fading seal]

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

public class bedScript : MonoBehaviour
{
    public GameObject inticon, bed, bedText;
    
    
    void OnTriggerStay(Collider other){
        if(other.CompareTag("MainCamera")){
            inticon.SetActive(true);
            if(Input.GetKey(KeyCode.E)){
                bedText.SetActive(true);
                bed.SetActive(true);
                inticon.SetActive(false);
            }
        }
    }
    void OnTriggerExit(Collider other){
        if(other.CompareTag("MainCamera")){
            bedText.SetActive(false);
            inticon.SetActive(false);
        }
    }
}```  how can i get my dialogue to look like this?

[languid spire]

do you have an Event System in your scene?

[polar acorn]

1. Do you have an event system in the scene?
2. Are you hovering over the text itself, since that's the target graphic? Hovering over a blank space like the emplty space inside of an a would not count.
3. Does your text component have "Raycast Target" enabled

[slender nymph]

use a coroutine to change the maxVisibleCharacters property over time on the TMP_Text object

[fading seal]

whats a coroutine and how do i do that

[mild onyx]

i am hovering over the text as for the other two you will have to give me some time as i have no idea what they are or where to find them

[polar acorn]

First one is simple, is there an object named Event System in the scene and does it have the EventSystem component on it?

Third one, it's a checkbox on all UI renderer components like your TMP Text

[mild onyx]

there is not, i put everything onto the button itself

[swift crag]

Not on the button.

Somewhere in the scene.

You can search the hierarchy for t:eventsystem

[languid spire]

screenshot your hiearchy

[polar acorn]

So no event system

[languid spire]

yep, no event system, add one

[swift crag]

you can find a template in the GameObject > UI menu

[polar acorn]

GameObject -> UI -> Event System

It gets created automatically when you add your first canvas, it's important, don't delete it

[hushed hinge]

seems to be working

[mild mortar]

Trying to work with a simple state machine, currently getting a consistent error message of NullReferenceException: Object reference not set to an instance of an object
IdleState.Tick (StateManager stateManager) (at Assets/Scripts/Enemy/IdleState.cs:15) which is this

if (lineOfSight.objects.Count > 0)
Anyone have any ideas? Not sure what I'm missing

using UnityEngine;

public class State : MonoBehaviour
{
    protected LineOfSight lineOfSight;
    private void Awake()
    {
        lineOfSight = GetComponent<LineOfSight>();
    }
    public virtual State Tick(StateManager stateManager)
    {
        return this;
    }
}

using UnityEngine;

public class IdleState : State
{
    PursueState pursueState;
    [Header("Detection Layer")]
    public bool hasTarget;

    private void Awake()
    {
        pursueState = GetComponent<PursueState>();
    }
    public override State Tick(StateManager stateManager)
    {
        if (lineOfSight.objects.Count > 0)
        {
            hasTarget = true;
            return pursueState;
        }
        else
        {
            return this;
        }
    }
}

[slender nymph]

i'm guessing line 15 of IdleState.cs is that if (lineOfSight.objects.Count > 0) since you don't assign to lineOfSight with that class?

[languid spire]

in Idlestate you need to call base.Awake().
Did we not do this earlier?

[mild mortar]

Yeah we did, that's where I said a bit earlier I ran into an issue and lost some progress.

Was trying to remember all the things I had done

[languid spire]

you could have just searched this discord

[mild mortar]

I lost a bit more than just that one bit, so it slipped my mind

[languid spire]

amazing, it didn't slip mine and it's not my code

[idle ginkgo]

what does this new keyword do?

i dont get it

[slender nymph]

the new operator is used to invoke an object's constructor. which creates an instance of that object

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/new-operator

[languid spire]

it makes a NEW copy of something
I want a Car, I get a new Car. I have a new Car

[summer stump]

Vector3 is an object (a struct specifically)
You are creating one (as the others said) with the values you want.

[fading seal]

how can i use a script inside of another script

[polar acorn]

Depends on what you mean by "use" and "inside"

Are you talking about referencing?

[fading seal]

yeah

[slender nymph]

get a reference to it

[polar acorn]

https://unity.huh.how/references

[fading seal]

do i use a game object?

[slender nymph]

all of your components will be attached to gameobjects

[tiny schooner]

hello guys

i have a problem

everytime i write a code in visual studio it appears in unity like nothing happened

[slender nymph]

it appears in unity like nothing happened
what do you mean by this

[tiny schooner]

i make a new script

i write my code

i finish

i go to unity

i dont see my work

[slender nymph]

please fucking finish a thought before pressing enter

[slender nymph]

and again, this is not clear what you mean. provide some actual details about what you are talking about. do you mean that the code just doesn't work? or do you mean that you didn't bother saving the code so unity does not see the changes to the file and has not attempted to compile it

[tiny schooner]

i mean when i finish a code on visual studio and click save then go back to unity i see the code but i cant drag stuff to the code

idk how to say it tbh

[swift crag]

you can't "drag stuff to the code"

[frosty hound]

Do you have compiler errors?

[tiny schooner]

no

[swift crag]

so i really do not understand what's going on here

[swift crag]

screenshot the entire editor window with the Console open.

[tiny schooner]

i can't send here for some reason

come dm

@swift crag

[swift crag]

You can send screenshots in this discord server.

so I don't know what you did wrong

[tiny schooner]

oh it js worked

[swift crag]

Your console window is not open.

[gaunt ice]

there should be a compilation error

at least one

[swift crag]

You are currently selecting a script asset. You can't do anything with this. You need to actually add the component defined by the script asset to an object if you want to assign things in the inspector.

That's my best guess of your problem right now, assuming you don't have a compile error.

[slender nymph]

those serialized fields would actually show up there if they didn't have compilation error(s)

[swift crag]

true

[tiny schooner]

how do check if i have errors?

[rocky canyon]

Console

[slender nymph]

look at your console. and also make sure that your !IDE is configured

[eternal falcon]

💡 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

[swift crag]

I've told you several times to show the Console window.

Click on the tab.

[rocky canyon]

compile error should show as a Red error.. or sometimes a Popup window directly telling u

[tiny schooner]

oh

i do have an error

[slender nymph]

yes we saw that from the code you shared

[rocky canyon]

lol

[tiny schooner]

lmao sry

im new

[rocky canyon]

dont be sorry for learning something new 😉

[tiny schooner]

thx man

[swift crag]

If you don't know what something means, ask for a clarification.

[rocky canyon]

no ones judging you for getting familiar and learning the editor

[tiny schooner]

alr

ok thank you guys ill learn how to remove the error from google or yt

[slender nymph]

you can fix the error by getting your IDE configured then re-typing that line since you'll have auto complete preventing you from making silly spelling mistakes

[swift crag]

alternatively, you could reveal what the error is

[slender nymph]

CS0246: The type or namespace collider could not be found (are you missing a using directive or an assembly reference?)

[summer stump]

Accessing the TYPE Transform on line 12, and perhaps trying to get a reference to transform from player (which is already a transform) are two that I see

[slender nymph]

ah yeah that one too

[tiny schooner]

yh thats the one

[summer stump]

C# is case sensitive
Things being capitalized or not make them quite different

[slender nymph]

gonna be honest, i completely missed the second one

[swift crag]

your IDE should be highlighting all of these errors for you

[summer stump]

I completely missed the one you said haha

[rocky canyon]

in ur face kinda squigglies.. make the world a better place

and all is right in the world lol

How can I do a 'While' loop in Unity?

People don't seem to like using 'while' with unity

[languid spire]

what?

while (condition) { }

[swift crag]

you use it exactly like you would anywhere else

I have fewer of them than foreach loops, sure

I use them when I need to do something until a condition is no longer true.

[west sonnet]

So when would you use a CoRoutine and not a while loop?

[swift crag]

those are two unrelated concepts

[west sonnet]

I'm trying to slowly change the size of a box collider over a period of time. Would a while loop or CoRoutine be better?

[polar acorn]

You'd use a coroutine when you want a coroutine.
You'd use a while loop when you want a while loop

[swift crag]

again, two unrelated concepts

[languid spire]

generally you would use a while inside a coroutine. With a yield in the whille

[swift crag]

a coroutine lets you run code that spans several frames

[polar acorn]

A while loop does not have any concept of "over time"

All loops always run to completion.

[west sonnet]

Couldn't a while loop do that too?

[polar acorn]

How?

It's a loop

[swift crag]

vitally, no code ever has the concept of running "over time"

[polar acorn]

it runs until the condition is false

[swift crag]

including code inside a coroutine

it's not like there are a thousand little virtual machines all running a single script's code, running in parallel

while (true) {
  // ...
}

if you hit this code, your game freezes

(assuming that nothing happens to make you exit that loop)

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

[summer stump]

A while loop will run as fast as possible if you don't do it in a coroutine or some other asynchronous method

Coroutines and while loops are not different ends of the same spectrum. They are completely different, and should not be compared the way you are

[swift crag]

to clarify: it takes zero in-game time for the code to run. Time does not pass at all in the game as your code is running.

it's not that the while loop runs really really quickly

it's that nothing else happens while your code is running

Unity makes a gigantic to-do list of every single thing it needs to run per frame, then runs through it in order

https://gdl.space/xonufunifu.cs

What am I doing wrong here? The code seems to go on forever until the collider is flat

[polar acorn]

Well, the conditions is all based off of size.y and offset.y which you are setting directly to -0.1

so I'm not sure what you're expecting to happen

[west sonnet]

I'm trying to reduce the height of the collider

[polar acorn]

if that condition is true, it sets them to -0.1

then waits 2 seconds and checks again

[west sonnet]

Ok shit

how can I minus them by 1?

[polar acorn]

Subtract 1 from their current value

[wanton kraken]

yo, fellas. i'm working on a top-down tank game, and i'm having a good amount of trouble coding the cannon to stop rotating past a certain point. how would you guys go about it?

[west sonnet]

How would I do that?

[polar acorn]

What do you actually want to do with those values?

You're doing the math but not doing anything with it

[west sonnet]

minus them by 1 each frame

[polar acorn]

This is subtracting 1 from them. What do you want to do with that new value

[west sonnet]

Make that the new value of the collider size and offset

[polar acorn]

So do that. Set the collider size and offset to the new value

[west sonnet]

It's not like this, is it?

[summer stump]

You need to use an = somewhere in that line

[polar acorn]

You still aren't doing anything with the result of your math

You're doing subtraction and then not using that for anything

[swift crag]

C# forbids you from writing a useless statement like that, which is why it's giving you an error.

[polar acorn]

This isn't going to modify the variable. Numbers are passed by value, it's going to give you the value that is 0.1 less than size.y

[swift crag]

For example, 4; is an invalid statement

[west sonnet]

This is correct, right?

[thin river]

Hello when I decide to use DOTS - does it mean - that all parts - that needs to communicate with each other - must be also converted (baked) to ECS.

For example:
I have Camera and Character in my main scene - and One Entity that want to read data from that camera and character.
Does it mean - that I need to move and convert camera and character into Subscene (and therefore convert it to ECS) ? Or there is possibility to somehow read data from gameObject from main scene from subscene ISystem?

[swift crag]

You should ask about this in #1064581837055348857 -- but I'd say the answer is "no". You can pass information back and forth just fine.

[polar acorn]

Yes, that would be actually using the result. It'd be used as the Y value of the vector you're setting the Size to

[thin river]

Oh sorry I missed that channel - but thanks!

[west sonnet]

Man, I hate IEnumerators 😄

but thanks for the help everyone

[polar acorn]

None of this had anything to do with IEnumerators

this was just setting a variable

[west sonnet]

I don't even know what I hate lol

[summer stump]

Apparantly the = operator

[west sonnet]

It would seem like it

[fading seal]

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

public class fridgeScript : MonoBehaviour
{
    public GameObject inticon, fridge, fridgeOpened, fridgeClosed;
    
    
    void OnTriggerStay(Collider other){
        if(other.CompareTag("MainCamera")){
            inticon.SetActive(true);
            if(Input.GetKey(KeyCode.E)){
                fridgeClosed.SetActive(false);
                fridgeOpened.SetActive(true);
                fridge.SetActive(true);
                inticon.SetActive(false);
            }
        }
    }
    void OnTriggerExit(Collider other){
        if(other.CompareTag("MainCamera")){
            inticon.SetActive(false);
        }
    }
}``` how can i make the fridge close if i press e again

[polar acorn]

Instead of setting each object to specifically true or false, set it to whatever value it currently isn't

[fading seal]

im a little confused

[polar acorn]

Well, let's take it one at a time. Do you know how to check if fridgeClosed is active

[fading seal]

in the code or?

[polar acorn]

yes

[fading seal]

no i dont think then

[polar acorn]

https://docs.unity3d.com/ScriptReference/GameObject-activeInHierarchy.html

Next: Do you know how to invert a boolean?

[fading seal]

no

[polar acorn]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/boolean-logical-operators#logical-negation-operator-

Now you know. Put those all together and you have the recipe to toggle an object instead of setting their SetActive to a specific value

[fading seal]

i dont get what any of those sites mean

[polar acorn]

It's called "documentation" and you're gonna need to get used to reading it

because that's like 60% of what programming is

[summer stump]

Look at the first bullet point in that link

[fading seal]

which one

[summer stump]

The most recent one

[fading seal]

what is a bullet point

[summer stump]

The dot before an item in a list

[fading seal]

oh yeah i forgot lmao

[fading seal]

yeah

[fading seal]

what about it

[summer stump]

That is how you negate a bool
Maybe I misread

[fading seal]

i have no clue what "Unary ! (logical negation) operator" means this is my first game

[polar acorn]

Did you try reading it

That's why I linked it

because it explains things

[fading seal]

ok i read it

now what

[fading seal]

what do i do now

[summer stump]

#💻┃code-beginner message

[fading seal]

im in code beginner

[summer stump]

Using what you learned to negate the current value of the bool

[summer stump]

That is a link to a message

[polar acorn]

Now you do the thing I said and set each thing to what it currently isn't.

[fading seal]

do i just copy what it says

[polar acorn]

What what says?

[fading seal]

bool passed = false;
Console.WriteLine(!passed);  // output: True
Console.WriteLine(!true);    // output: False```

[polar acorn]

This is what we call in the business "an example"

you're supposed to read it

and see how it works

and apply it to your own project using a thing we like to call "thinking"

[fading seal]

im trying to learn this from scratch

[summer stump]

Then read the links more fully and do so. Asking here is not learning from scratch

[polar acorn]

You currently know:
A) How to set an object's active state to a boolean
B) How to invert a boolean
C) How to get the object's current active state as a boolean

From there, it should be straightforward to:
Set the object's active state to the inverse of its current active state

[summer stump]

Google more examples if needed

[fading seal]

i dont know if i dont understand it

[polar acorn]

which step do you not understand

[fading seal]

what does "console" mean

[summer stump]

Console is completely irrelevant to you

[polar acorn]

Console.WriteLine is how you output text to the C# console when writing standalone programs

and has absolutely nothing to do with anything right now

[modest dust]

I feel like there's a severe lack in general C# programming knowledge and that should be dealt with before even coming near Unity

[polar acorn]

I mean, it's okay to not know C#, but you need to at least know logic

[summer stump]

The example is meant to show you how to use !
That is the important part here

[fading seal]

i have zero experience in any of this i just wanna make a simple game

And there's also a lack of that logic, so it would be best to at least learn C# first and "learn the logic" alongside it

i dont understand how to use this https://learn.microsoft.com/en-us/dotnet/api/system.datetime.op_greaterthanorequal?view=net-8.0#system-datetime-op-greaterthanorequal(system-datetime-system-datetime)

i want to check with the if function if the System.DateTime.Now.Hour which returns current hour is later than hour 21

is it like a special boolean or something?
