I assume I should then increase it until this no longer becomes an issue? Though I may need to create conditions for this increase, as a value of 0.1f still had this edge problem, but also made the player noticeably uncurl slightly earlier than they should when landing normally.

[bronze zenith]

im certain these are fine tho

wait what do you mean printing the stuff in my code

[willow scroll]

Some is certainly not fine if it's not working

[unique slate]

idk if i have trouble with it, the thing i wanted to work 4 hours ago finally works now, i can look at the rest tomorrow. its 23:47 here and i rly want to sleep since 2 hours xd
From what i can see its just a bunch of referencing errors that i will have to fix because its coded for a single variable instead of a list, nothing big.
Can i PM you in the next few days if i rly cant make it work for some reason?

[willow scroll]

Using print or Debug.Log methods

[willow scroll]

Consider pinning me in this channel. Good luck.

[bronze zenith]

how?

[deft grail]

google it

try it

find out how it works

do a couple things with it

[bronze zenith]

if i dont fix this within the next hour im just gonna sleep cause itl be 11 pm

[deft grail]

cool?
that doesnt mean you cant learn how to use Debug.Log within 1 hour

you should easily be able to debug your game within 1 hour and fix the problem

[bronze zenith]

yea

it says ; expected and then when i put a ; on the end of the line it says to i get 90 more errors

[deft grail]

if it says ; expected doesnt always mean you need a ; there, it might mean theres other errors near it that cause it to say ;

what line is the error on and which script

[bronze zenith]

oh wait nevermind

its ok

where am i putting debug log

[deft grail]

where you want it to run

for example before and after setting a value of something

[summer stump]

Usually that error means it is missing a semicolon BEFORE that line, or something else as gr4ss said

[bronze zenith]

ok not gonna lie i think i might just not add crouching for now

im gonna keep the code incase i can work something later

[deft grail]

you can comment a line by // or a whole section by

/*
code
*/

[bronze zenith]

alright thx

[candid nimbus]

hi ! Can somebody explain me why some Unity built-in features like coroutines generates GC Alloc which later cause from time to time game to free. My game logic si 2 ms per frame and then when GC incremental collect is called, the cpu time is 60 ms

[rich egret]

public List<Item> Items = new List<Item>();
public HashSet<string> itemNames = new HashSet<string>();

How is it possible to make the lists into one "shared" list? (Note that one list is a string and the second list is a GameObject)

[wintry quarry]

allocating any object on the heap will cause GC allocation.

[jovial sable]

how do i reset a integer? like if i press it 10 times it will go back to 0

[wintry quarry]

wdym by a "shared list"?

[deft grail]

this is basic C#

[wintry quarry]

how does one "press" an integer?

[deft grail]

just setting a value

[jovial sable]

idek

im just tryin something

[candid nimbus]

but for games, that GC collect is a killer of quality

[solar charm]

can someone please explain to me what this means?

[rich egret]

You know, it would be the same list, but the problem is that each one is of a different type

[deft grail]

you didnt assign the button

do you assign it anywhere?

[wintry quarry]

so don't allocate as much stuff on the heap, and make sure you reuse things whenever possible.

[solar charm]

thank you so much!

[solar charm]

im not really sure i was just following a tutorial

[wintry quarry]

it means the createNicknameBtn reference is null. when you tried to use it

you didn't assign it properly

[deft grail]

probably missed the part of them assigning it in the inspector, or didnt get to it yet

[wintry quarry]

WHich means you missed something in your tutorial

[wintry quarry]

Not possible since they're completely different types.

[solar charm]

ok ty ty yeah i think that might be it

[bronze zenith]

OH I DID IT

I CORUCH

CROUCHED

[rich egret]

Suppose they were one type

[bronze zenith]

i forgot to make it something you can do in input manager, im so dumb

what a waste of time lol

[deft grail]

then you can make 1 list, there is nothing to "suppose" here

[wintry quarry]

then you just assign with =

but your example is a List and a HashSet

those are two different things

[deft grail]

that is the exact reason you use Debug.Log and figure out that your code is not running, then you would figure out its because of your input

[bronze zenith]

yup

[devout flower]

is there a physics-based way to scale up an object? i want to scale an object until there's no space but it's causing problems (btw, for future reference, would i put this in the coding or physics channel, since it has both)

[wintry quarry]

I think what you're actually asking here is "How do I make it so my set of items and my list of strings never get out of sync." The answer to that is:

• Judiciously updating them both at the same time
• Getting rid of one of them entirely, and using the remaining one as the only source of truth.

[waxen adder]

Not sure where to ask this. How can I tell what render pipeline was used from one of my previous projects?

[slender nymph]

not a code question. but why not just open the project and look?

[wintry quarry]

The first setting under Graphics in Project Settings.

[waxen adder]

ty

[solar charm]

i have a button that i cant type in it, can someone help me please?

[deft grail]

how are you making it so that you can type in it

[solar charm]

its a prefab so i didnt make it

[deft grail]

so how do you want to be able to "type in it"

[solar charm]

i know im not giving you a lot to work with im sorry 😭

[deft grail]

well of course, you cant "type" in a button

[solar charm]

basically i want to be able to type in the input field when i press on it using my mouse

[solar charm]

oh im sorry i didnt mean button, i meant input field

[deft grail]

do you have an EventSystem in your scene?

[solar charm]

basically i cant type in the box that says "enter text"

[solar charm]

i dont think so, how do i install it into the scene?

[slender nymph]

it should have been added to the scene automatically when you added the first UI object or canvas

[deft grail]

like you create a new game object, its under UI > EventSystem

[solar charm]

i have textMeshPro, does that count as an EventSystem?

[deft grail]

a TMP is a TMP

[slender nymph]

no, the EventSystem is a specific component

[deft grail]

a EventSystem is an EventSystem

[deft grail]

which you can find under ^

[final totem]

i want to disable the rigid body how can i do it?

_rb.enabled = false;

[solar charm]

OHHH i think i know what you mean, no i do not, how do i install it into the field?

[slender nymph]

either make it kinematic or destroy it. rigidbody does not inherit from Behaviour and therefore has no enabled property

[deft grail]

you already asked this question and i already replied

[solar charm]

oh, mb

[final totem]

whats kinematic tho? static but whats different?

[slender nymph]

https://docs.unity3d.com/ScriptReference/Rigidbody-isKinematic.html

[final totem]

gotcha, other question, can i support controller and stuff if i use the legacy input system (if getkey.............)

[deft grail]

yes but it would be much easier to use the new input system

[rocky canyon]

sure, if u check out the Input Manager you can see that Unity already has multiple bindings for their preset inputs

but like gr4ss mentioned, the newer input system is well more suited to support multiple input types and binds

[stable lagoon]

how can I fix this?

[wintry quarry]

Are you using Visual Scripting?

[stable lagoon]

oh nvm I fixed it lol

[stable lagoon]

this problem came back and now I cant fix it. any help?

[north kiln]

Perhaps answer the question that was asked?

[stable lagoon]

yea I am

[deft grail]

where

[summer stump]

That was their answer. Yes, they are using visual scripting

[deft grail]

ah ok, english doesnt make sense to me

[stable lagoon]

anyone know how to fix it?

[north kiln]

Presumably regenerate those generated files. I'm not familiar with the VS package to know how you do that

[stable lagoon]

gotcha

it didnt work

[teal viper]

How did you fix it back there?

[stable lagoon]

I just closed the editor and reopened it

[teal viper]

You seem to be working with some unity tutorial project?

Did you open it with a compatible editor version?

Is the installed visual scripting package compatible with your editor version?

[stable lagoon]

lemme check

[stable lagoon]

when I made the project I used the vr template

thats my version

didnt feel like typing it out lol

[teal viper]

What tutorial is that?

Also, when do the errors appear?

[stable lagoon]

It was working fine yesterday

but the errors started popping up when I edited a script from a package I was using

[teal viper]

Does it appear when you try to build the game?

[stable lagoon]

yes

[teal viper]

Well, editor API can't be included in a build.

The scripts with the errors seem to be generated by visual scripting package. And I don't know enough about visual scripting to tell if that's correct or not. Might want to ask in #763499475641172029

[stable lagoon]

gotcha

thanks

[teal viper]

My guess is that these generated files should be in a Editor folder. Did you move them around perhaps?

[stable lagoon]

I did move one

[summer stump]

Do you remember which one? Can you move it back?

[stable lagoon]

I just moved it back

ohh shii I think yall fixed it

I rly apricate yalls help

thanks

[teal viper]

For future reference: don't move autogenerated folders and files without completely understanding why they are placed there.

[red siren]

I have a really basic question, but I'm wondering about stuff in term of approach. I have a game where the player has to shoot but this is how it works : There is a bar that has a pointer on it, and that pointer moves in a sine wave all over the bar (left to right). The player presses space, then another bar appears and it does the same vertically. Then it shoots. Then it goes back to the beginning of the flow. Imagine shooting darts and aiming horizontally and vertically in separate game states.

I'm thinking of a state machine, but I wonder if there is a better approach built into unity?

[summer stump]

No, there is nothing built into unity to do that

[wintry quarry]

Yes a state machine is a good idea here

to orchestrate things

[red siren]

I've seen some people use the animation flow chart to do state machines, is that just a hack to help visualize or a good idea?

[summer stump]

I mean, I guess you could.
I would just do it in code. That is definitely my bias though

[red siren]

I think I would do that too

[nimble cliff]

Hello,

its not possible to reference a Subscene in a ScriptableObject ? This one (the public field) get cleaned up every time I close the editor. Thank you

[red siren]

Now, since I have different UIs and whatnot that will be displayed in each state, would it be a good idea to have those objects inside dictionaries and disable / enable them depending on the state (I use the state as the key to the dictionary, for example)

[summer stump]

Maybe ask in #1062393052863414313
I have never tried, but they would know most about subscenes

[nimble cliff]

ho right I forgot its part of entities , thanks

[summer stump]

That seems reasonable.
Could be as simple as an array and just use index 0 and 1, if you ONLY have the two bars. If there are more and they don't increment clealy like that every time, then a dictionary would be a good idea

[red siren]

I'm hesitating between that and an event system

Where on state change they listen to it and enable / disable themselves? Not sure. That's where I'm a bit confused atm.

[acoustic arch]

my abilities SO has an enum that is set inside the inspector

i want to reference that to check whether the card is strong or weak against whatever its facing to double damage or not

but the only option for referencing an enum within it that its giving me is by the actual SO

https://paste.ee/p/PjZFY

ability SO

will i need to make a seperate class for typings?

[fading trench]

put the enum outside the ScriptableObject class

[acoustic arch]

alright then how would i reference to put it inside of my SO?

[fading trench]

make it public

[acoustic arch]

did not work

https://paste.ee/p/rOQgr - contains the enum

[slender nymph]

yes you need to reference the ability SO in order to access its enum variable

there is no other way

[fading trench]

put the enum outside the class, like an interface

[acoustic arch]

oh wow i didnt know that was possible

thanks

[slender nymph]

ah, i assumed you were trying to access the enum, not create a variable of that type because you were talking about "referencing" it.
yes, enums are just a type so they can be declared right out in the namespace, just like any other class, interface, or struct

[acoustic arch]

worked

[acoustic arch]

super useful information actually

ecspecially for structs

too

[slender nymph]

and when a type is nested inside of another type (like an enum nested in a class) then that outer type is part of the fully qualified name of the nested type. so public class MyClass { public enum MyEnum { } } when used outside of MyClass, but in the same namespace then MyEnum is called MyClass.MyEnum

it's not an object reference, it's just part of the type's name

[acoustic arch]

i noticed that

thats the reason why i couldnt reach my abilities type

technically they all had their own enum which was bad in itself

now anything needing a type can easily have one (type as in my in-game type)

[slender nymph]

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

[queen adder]

so ig no?

[slender nymph]

i mean, if the intention is to check whether you are in play mode or not, then no that is not going to be a conditional compile symbol. you can check if you are in the editor for it though

[teal viper]

That would be super inconvenient, as you would need to compile your game code both for the editor and player.

[queen adder]

uh, isnt building supposed to recompile stuffs itself anyways??

[teal viper]

There's a bool you can check to run code only in edit/play mode. https://docs.unity3d.com/ScriptReference/Application-isPlaying.html

[queen adder]

ah i see

yea would have to double for play/edit mode gotcha

[teal viper]

Yes, but for that you have the platform defines, like UNITY_EDITOR

You don't build your game every time you enter play mode in the editor to make it clear.

[queen adder]

im using isplaying now, just weirdly got curioused if theres an coindition symbol

[slender nymph]

that would require a complete recompile just to enter play mode

[hasty spire]

im trying to work with the new input system its coming up with a null reference on line 39 but idk why it is doing that

[slender nymph]

most likely UserInput.instance or UserInput.instance.controls is null

[rocky gale]

Did you enable the input in onenable?

[slender nymph]

the input not being enabled would not cause a NullReferenceException

in fact, it would have to be not null in order to enable it

[hasty spire]

thank i think i figured it out

[queen adder]

is it just me or KeyCode.Question isnt SHIFT + /?

[teal viper]

Maybe a non standard english keyboard layout?

[queen adder]

it doesnt work on you aswell?

[teal viper]

Wdym?

[slender nymph]

in non-stone age unity versions the Use Physical Keys option makes that keycode useless

not sure how it works on your prehistoric version

[queen adder]

physical keys option?

[slender nymph]

it's an option in the input manager. dunno if it's in your ancient unity version

[topaz mortar]

what's the proper way to make sure input works on all devices? keyboard/mouse, gamepad, steamdeck, mobile, more?

[charred spoke]

The proper way? Test it on each device.

[topaz mortar]

no which system do I use for it?

I've been seeing a lot of new/old input system talk here, but dunno what that is

[charred spoke]

The new input system

[topaz mortar]

which is? or can I just google "unity new input system"?

[charred spoke]

You can just google it yes

[willow scroll]

The old input system can be set up via Project Settings -> Input Manager. In order to use the new input system, you'll have to install the Input System package in the Package Manager.
You can adjust the input for all the devices using both of them, but the new input system is usually considered much better, because of its increased adjustability and a big variety of inputs.

[charred spoke]

https://docs.unity3d.com/Packages/com.unity.inputsystem@1.8/manual/index.html

[willow scroll]

It's simply called "new input system", yes

Actually, it isn't really hard to use, and so, I would recommend it for your game

[topaz mortar]

I'll take a look at it, thx

[queen adder]

how to check if the player collides with a specific gameobject

[slender nymph]

before an answer is provided, can you explain the purpose of doing so? that way a proper solution can be provided

[queen adder]

2d platformer game, player falls down, i take 1 of their lives

if theres another way of doing this btw itd be better bc my friend said sometimes you can clip through objects if youre too fast

[slender nymph]

well in that case you don't necessarily need to check for a specific game object, you can check a tag or use TryGetComponent

[queen adder]

how do i chrck tags

[slender nymph]

you can use the CompareTag method in your OnCollisionEnter2D/OnTriggerEnter2D

just make sure that your player or the object it is colliding with has the tag (depending on which object you are checking from)

[queen adder]

can you explain a bit more? i‘m in a gamejam and i‘ve never used this before so

[willow scroll]

You have to make sure both objects have colliders and the desired one the tag you need.
Check out OnCollisionEnter2D

[slender nymph]

perhaps you should take some time to learn how to use the unity engine before you participate in a jam, there are excellent beginner courses pinned in this channel

[queen adder]

ik how to use unity, not tags

[willow scroll]

But tags are considered "the basics"

[rocky gale]

Ye tags are pretty basic

[willow scroll]

Have a look at this

[queen adder]

i mean the point of a gamejam is to learn so

i guess here we are

thanks guys

[rocky gale]

Yes it is good

To learn

[slender nymph]

surely you know how to detect a collision, yes? and you know how to call a method on an object. so naturally your next step should be to google the CompareTag method to see how you would use it. it's not some high level concept that requires a tutorial, but if this is too much for you to figure out on your own then you need to go learn the actual basics

[noble river]

Hello. I'm running into an issue where the text input fields in my game only detect clicks on their leftmost side. Any similar experiences and/or fixes?

[queen adder]

brother there's no shame in not knowing

[slender nymph]

sounds like something is blocking the raycast from the mouse. make sure there are no raycast target objects in front of the input field.
also not a code question #📲┃ui-ux

[slender nymph]

i never said there was. there is shame in intentionally not bothering to learn what you are doing and trying to pass it off like you have done so or insisting you don't need to so that other people have to put in more effort to help you 🤷‍♂️

[queen adder]

how tf am i supposed to learn if i dont know what to google bro

you just told me and i went to google it

but yeah again thanks idk how many times you want to hear that but thanks before this starts to get disrespectful

[willow scroll]

You inability to use google it not their problem.

Probably, you first want to use this tutorial

[queen adder]

very funny joke, i think you didnt understand that i meant i didnt know what i was looking for rather than how to press keys on my keyboard to search

[willow scroll]

You may be muted if it starts to get disrespectful

[queen adder]

if you've never heard of something how can you google it bruh

[willow scroll]

I see, perhaps I have underestimated your abilities

Pressing the keys is a really great start. Now, you want to find the suitable keys for typing "unity tag", "unity comparetag", "unity oncollisionenter2d" etc.

[queen adder]

i dont think you still dont understand what "never heard of" means

obviously i've heard of it after this very amazing person told me about them

and i went to gogole

thanks for your concern though

[charred spoke]

Sigh I recommend you go through !learn to get your bearings first. The guided tutorials there will do you wonders.

[sand lichen]

I tried to disable the movement script when my cursor is unlocked and shown

private bool isCursorVisible = false;
private bool isCursorLocked = true;
public FirstPersonController firstPersonController;
void Start()
{
SetCursorVisibility(false);
SetCursorLock(true);
}

    {
        ToggleCursor();
    }
}

void ToggleCursor()
{
    isCursorVisible = !isCursorVisible;
    isCursorLocked = !isCursorLocked;

    SetCursorVisibility(isCursorVisible);
    SetCursorLock(isCursorLocked);
}

void SetCursorVisibility(bool isVisible)
{
    Cursor.visible = isVisible;

    if (isVisible)
    {

    }
    else
    {
        // disable cam move
        firstPersonController.enabled = true;
    }

It told me "The type or namespace name 'FirstPersonController' could not be found (are you missing a using directive or an assembly reference?)" but the script name is FirstPersonController.cs, where did I do wrong? (sry Im completely new in c# and joined an advanced course.)

[sand lichen]

ok thanks Ima try to figure that out❤️

[acoustic arch]

alright this next week for my game is creating the enemies battle AI in the card battles

anyone have any tips for creating a calculation for the best decisions in battle based on typing, health, and attacks?

[languid spire]

#archived-game-design

[quick pollen]

thats not game design

its more like an equation

[topaz mortar]

it's kinda both

but since we have no variables for an equation, it would become more of a game design question I guess

[quick pollen]

technically you could create an actual AI

like make AI play your game

and reward it if it beats an other AI

[acoustic arch]

sounds a little out of my range

[topaz mortar]

that's probably not the way to go since we're in a beginner channel lol

[topaz mortar]

what kind of tips are you looking for?

[quick pollen]

you just need neural networks, but yeah its not the most beginner friendly

[acoustic arch]

i'm certainly not a bad programmer but i got like 7 months under my belt of pure laziness

[acoustic arch]

if anyone has experience making an enemy decision making in a custom battling game

how might i go about turning the types, health, abilities into maybe like percentages or numbers in a calculation

[topaz mortar]

https://www.youtube.com/results?search_query=ai+for+card+battler+unity

[topaz mortar]

you could assign a weight to each factor and then use the option with the highest weight
for example a damage card that can destroy another card gets a very heigh weight
a type card that targets a type it's weak against gets a low weight
a type card that targets a type it's strong against gets a higher weight ...

[quick pollen]

plus you can also give health a weight too

the lower the health, the higher the weight

so it focuses on trying to heal

[magic panther]

I have three walls and a crate on the map rn. I see 4 wall messages and a crate message. Shouldn't overriding change what happens in a function? Or did I mess up the syntax

that's not helping

you want me to write the 2 lines of code in separate documents through a website to limit chat flooding?

[acoustic arch]

yeah that's what i was thinking

[quick pollen]

no, you should just sent it like this so people can actually copy it or edit it

[topaz mortar]

do you actually need virtual & override for stuff this basic?

[quick pollen]

i was about to ask too

[magic panther]

one sec mate

[green ether]

I think its more about the basics and learning how it works?

[quick pollen]

ive made some pretty big systems already and messed around with classes quite a bit but I never had to use override or virtual

[green ether]

Its very useful in alot of cases/

[magic panther]

https://hatebin.com/recjvazbmm
https://hatebin.com/mcjfrngtqn

[green ether]

The syntax looks correct

[quick pollen]

idk ig i just didnt use inheritance all too much yet

[green ether]

Do you have both script attached to one object?

[topaz mortar]

it looks like it's actually required if you want to overwrite a function so guess it's fine 🙂

[quick pollen]

tbf I probably should be using inheritance because I'm making a bullethell and projectiles could use it, but idk how to honestly

[topaz mortar]

well you just got a very simple example 🙂

[green ether]

maybe add , gameobject to the debugs and check which one is sending it twice?

[quick pollen]

like I have this example

[green ether]

But I assume you just have the script for wall **and **crate on one of them, cause the syntax is correct im pretty sure

[quick pollen]

and I have a lot of projectiles that have the same setup but different values

but idk if thats what inheritance is used for

[green ether]

If all of your projectiles are prefabs then I guess this works

[rocky gale]

Ye why do you need virtual and override for that

[quick pollen]

i was asking if i do

or like

if i could make it more efficient somehow

[topaz mortar]

nah, inheritance is if you want to use the same function but get different results
for example a class Animal could have a function Speak
then the class Cat would return "Miauw" and the class Dog would return "Waff"

if your bullets do not behave differently in the same situation/function, I think there's no need

[quick pollen]

I see, thanks!

[topaz mortar]

I've never used it myself

[quick pollen]

I mean

[rocky gale]

“Miauw “ and “waff” 💀

[quick pollen]

yeahh i probably dont need it

[quick pollen]

it was actually a really good explanation

[topaz mortar]

programmers tend to make things more complicated instead of explaining them 🙂

[rocky gale]

No the explanation was great I was just surprised by miauw instead of meow and waff instead of woof 😂

[topaz mortar]

I'm Belgian 😅 It's miauw and woef here

[rocky gale]

Oh I see my bad 😅

[green ether]

As long as your bullets are this simple you dont need it. But what if you want one bullet to have an additional effect thats unique to this bullet?

With inheritance you can derive from the baseclass "Projectile" and still have all bullet functionality. Without it you have 2 different classes with only a small difference and if you need to access the script youre gonna have to look for 2 different scripts now on each projectile. And it just gets worse the more you have.

[topaz mortar]

but why wouldn't you just add that extra functionality to the base class instead of bothering to add inheritance?
if the classes are like 2000 lines long then yeah, but in most cases?

[green ether]

Inheritance is pretty important for alot of things and the basics of oop, you technically dont need it but you can do many more things much more efficiently if you know this.

[green ether]

Well you dont want functions on a projectile that dont belong to it right

[topaz mortar]

why not?

[rocky gale]

Ye I love inheritance

[topaz mortar]

it's just a few lines of code that never get called, I don't see the issue? maybe that's why I've never used it 😛

[green ether]

Why would the dog class have a function for saying "Meow"

its gonna get extremely unreadable and harder to maintain after a while

and the more you add the worse it gets

[topaz mortar]

because if my world only contains 2 animals it would be easier to make a function Bark() and a function Miauw() instead of adding inheritance

[green ether]

no

[topaz mortar]

yeah this, but in most cases you never get that far, at least I've never had any code that required this because it got too complex

[green ether]

Even then I would much more like to have a function called "Make sound"

and not have to check first which function I need to call now

[quick pollen]

this is what I mean btw

[rocky gale]

It’s also cleaner

[green ether]

Or for Items, in my game I dont want to have a long switch case or 20 if-else statements for using items:
I dont want to check for which item I am currently holding to use the correct function:
I just call the UseItem function and each item will know what to do

[quick pollen]

i sent a 1 min video but basically the first 20 seconds explain what I mean

[topaz mortar]

Hmm I might be doing this 🤔

Thanks!

[willow scroll]

Or an event

[magic panther]

ok, sorry for not rtesponding, had to do something rq

[green ether]

I guess yeah but no need for it right?

[willow scroll]

Mm, I don't fully know the issue.

[magic panther]

nothing even shows up

[willow scroll]

Looking lit

[green ether]

click on the debug

[rocky gale]

Should be public virtual void no?

[green ether]

it should highlight the item in the scene view

[quick pollen]

im not even quite sure what you want to achieve here

[quick pollen]

ty :)

[magic panther]

both from the crate

[green ether]

Could be? I also do it with public first

[rocky gale]

Ye

[quick pollen]

does the order even matter?

[green ether]

Does it make a difference?

yeah not sure

[rocky gale]

I mean maybe it doesn’t matter but just weird seeing it like that

Idk

[green ether]

yep

[magic panther]

I never used this stuff, just checking it out. Ill try that

no difference

[rocky gale]

Yea didn’t think so

[magic panther]

test

[green ether]

And you sure you only have one script on the crate?

[quick pollen]

public protected internal private new abstract virtual override sealed static readonly extern unsafe volatile async

[willow scroll]

The order doesn't matter here

[magic panther]

I'm an idiot xd

[quick pollen]

this is the order I got from googling

i can only guess what volatile means

I know what async means

[rocky gale]

Ik but it’s unconventional

[rocky gale]

Tf is thst 😂

[willow scroll]

Too many errors

[magic panther]

It's a prefab variant, forgot to remove it

[quick pollen]

wdym

[green ether]

told you all the way up here @magic panther xD

[willow scroll]

A static method cannot be virtual, override etc.

[rocky gale]

They were saying order not one variable/method

[willow scroll]

Alright

I thought it was a joke first.

[quick pollen]

this might just be a coding convention and not smth that matters

[rocky gale]

Oh

[rocky gale]

Ye I think so

[magic panther]

I missed your message, my bad

also one last thing

https://hatebin.com/imhmadcoja

[quick pollen]

it has to do with multithreading or something

[magic panther]

this is the player script

and it has an error in it

[quick pollen]

like it can be accessed by multiple threads at the same time

[willow scroll]

Share the error

[magic panther]

because what it should do is trigger an Interact function in the collided object

the Start was for testing, I renamed it to Interact now in both scripts, all is the same apart frtom that

[magic panther]

It's just because I don't know how to trigger the function

[willow scroll]

Collider doesn't have an Interact method

[magic panther]

ik

[willow scroll]

Then why use it?

[magic panther]

what do I replace collider with

[quick pollen]

honestly id use some sort of other function that isnt Start

[willow scroll]

Which class' method is it?

[magic panther]

I did use another one

[quick pollen]

oh

[magic panther]

changed just now

np

[quick pollen]

yea mb

[willow scroll]

Which class got it?

[quick pollen]

but how do you call it

[magic panther]

Wall and Crate

[willow scroll]

Then call it on them

Via GetComponent<T>

[magic panther]

the perfect outcome is to check if the hit object has an Interact function and if it does, call it

[willow scroll]

Check it with TryGetComponent<T>

[magic panther]

where tho

[fossil tree]

so that do something like that ? ```using System.Collections;
using System.Collections.Generic;
using Unity.VisualScripting;
using UnityEngine;

public class Build : MonoBehaviour
{
public GameObject prefab;
public Cellule cellulePrefab;
public List<GameObject> instances = new List<GameObject>();
// Start is called before the first frame update
void Start()
{
for (var a = -50; a < 50; a++)
{
for (var i = -50; i < 50; i++)
{
Cellule newCellule = Instantiate(prefab, new Vector3(i , a, 0), Quaternion.identity);
newCellule.build = this;
instances.Add(newCellule);
}
}
}
public class Cellule
{
public Build build;
}

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

}

[willow scroll]

if (hitInfo.collider.TryGetComponent(out Wall wall))
    wall.Interact();

[magic panther]

there are other scripts that have it, there's other wall types

like the Crate

which expands the Wall

[willow scroll]

Which should all be inherited from Wall

[magic panther]

so this will work?

[willow scroll]

No, I've just posted a random piece of code, which is not supposed to do anything

[magic panther]

got this error

[willow scroll]

Where is the line 41?

[magic panther]

this one

precisely the if statement

[willow scroll]

hitInfo is null

[magic panther]

oh yeah xd

[willow scroll]

You don't use the canMove boolean

[magic panther]

hitInfo != null

[willow scroll]

No, use canMove

if canMove is true, hitInfo is not null

[magic panther]

ok, so canMove &&

as both of these ifs checked for canMove, I rearranged it like this

[willow scroll]

I mean, its collider is not null in this case, as RaycastHit is a struct which cannot be null

[magic panther]

same error again

https://hatebin.com/tfnpggkqwo
Player Script

[quick pollen]

something is null

[willow scroll]

Why is it reversed.

[magic panther]

one sec brb

[willow scroll]

bool canMove = !Physics.BoxCast

[quick pollen]

(hitInfo.collider.TryGetComponent(out Wall wall) returns null

[willow scroll]

You should either remove the ! or check for !canMove

[willow scroll]

It doesn't

It returns an error

As collider is null

[quick pollen]

well...... it returns null so it returns an error

yea

[willow scroll]

It doesn't fully return null

[quick pollen]

what I mean is that smth in that line is null

a.k.a. collider

[willow scroll]

hitInfo.collider returns null, and trying to get the component from null results in an error

[willow scroll]

And this fixes it

[slender nymph]

the raycast hit nothing, you check the result anyway. you only don't check it when the raycast was successful

[modest dust]

canMove == true here implies that the cast didn't encounter a wall, so check for !canMove instead

[magic panther]

wdym reversed

[willow scroll]

It's better to remove the !, as moving when canMove is false isn't logical

[willow scroll]

Read my next message

And, perhaps, a few after that

[magic panther]

If I had to rewrite it like this I'd change the variable name tbh

removed the !

i'll test it

[willow scroll]

It won't work

[magic panther]

yeah I can't move

[willow scroll]

You either remove the ! before the cast, or put the ! before the condition

Not both

[magic panther]

rewritten

oh damn

yall are wizards, thanks so much for help

works perfectly

[modest dust]

What isn't logical is moving when canMove is false, so that should be changed, as he did now

[willow scroll]

Isn't it literally what I've said?

[modest dust]

You were talking about removing the !, so I assumed canMove = Physics.BoxCast, which would return true for encountering a wall and implying that it can then move, which wouldn't be logical

If that's not it, then my brain is fried, I had 3 hours of sleep.

[magic panther]

I simply forgot to change the variable name after implementing the !

it almost was cantMove

which sounds dumb as hell

[willow scroll]

It does

[magic panther]

Imagine

[prime karma]

hey, im making my character abble to dash following a tuto but i dont understand why he dash only in one direction even if i walk in an other direction, can someone help ?

[narrow girder]

I was trying to create a button and connect it with my script but idk what i should input here

[fading trench]

cause your velocity vector is in fixed direction, aka your transform.localScale.x

[queen adder]

I know it's confusing, because when you turn left you flip your local scale from positive 1 to negative 1, instead of flipping your character using the scale, use

this.GameObject.Rotate( 0, 180, 0);

using the Rotate Method, will save you from a lot of headaches in the future.

[bronze zenith]

ok so im making a new movement code https://hatebin.com/jsdkqtfasu why isnt it working

there is NINETY errors

[languid spire]

maybe share those, we are not mind readers

[prime karma]

oh okay cause when i flip i only change the sprite renderer x, so i have to change my void flip ? or have to change in dash ? sorry im starting so i dont get eveything ://

[bronze zenith]

all of them are just uh

ambiguity between x and y

[languid spire]

on line 43 ?

[bronze zenith]

no theres way more then just that

[languid spire]

then show them

[bronze zenith]

there is one in nearly every line

[queen adder]

Just your void Flip()

also, leave the scale at positive 1

once you add the Rotation Method, you will no longer need to mess with Scale

[prime karma]

ok ok ok lets try it thanks a lot

[languid spire]

@bronze zenith if you will not supply the requested information why are you asking for help and how do you expect us to provide it?

[bronze zenith]

i was trying what the other guy said but im not good with code so im struggling

ill give the error information

[queen adder]

try this @bronze zenith https://hatebin.com/sgnpogrycr

[bronze zenith]

i cant actually fit them all on one screen

[languid spire]

does not matter, just screenshot the console with the first error selected

[bronze zenith]

ok

[queen adder]

sorry, try this one instead https://hatebin.com/pnqqgfaytm

I forgot to change a word

[languid spire]

OK, you have duplicate scripts (PlayerMovement) , sort that out first

[bronze zenith]

but theres one place playermovement is used

[languid spire]

not about used, in your project

[bronze zenith]

oh wait

[queen adder]

https://hatebin.com/ghfzztckyk

dang, lol I keep forgetting the add the paranthesis

this one should be fine @bronze zenith

[bronze zenith]

ok

but i gotta find the other scripts

[queen adder]

np, let me know if that worked

[bronze zenith]

i found the scripts

i deleted them from the player

but not the actual game

(before)

yeah now theres no issues found

thanks guys

ok theres 8 more errors

same code

every time i use rb it doesent exist in the current context

nvm, think i fixed it

[narrow girder]

Hello, How do i connect both animations in my script to make it functional?

[rich egret]

public HashSet<string> itemList = new HashSet<string>();
How can i see this list in the Inspector?

[barren vapor]

do you mean console log?
in that case:

[gaunt ice]

google unity serializable hashset

[willow scroll]

No, they mean serializing it in the Inspector

[barren vapor]

oh

[rich egret]

No, in the inspector

Like this

[willow scroll]

You may want to either implement a struct yourself, convert it to a List, or use the marcospgp's answer on Unity's forum, which internally converts the HashSet to a List

The link doesn't seem quite right

Now it works. Links don't seem to support specific highlights

[willow scroll]

It's weird how to check them with CircleCastAll

[gaunt ice]

btw they should use grid not a circle cast nor any physical query

[fossil tree]

its the only way i find so...

[willow scroll]

You should store the cells in a List of structs

[gaunt ice]

yes sparse array should be better i think.....
or even quad tree

but grid is simple enough for beginner

[willow scroll]

It's limited to be rectangle-only

[fossil tree]

what is that

[willow scroll]

A list of structs.

[fossil tree]

and i need raycast for check only near cell

[willow scroll]

Don't do it

Consider, probably, having a List of Cells, where struct Cell has its Vector2 position and a reference the block, or whatever you're using

And, yeah, you're not checking them correctly

You have to check each cell's position with the following directions:

private static readonly List<Cell> _directions = new()
{
    new(-1, -1),
    new(-1, 0),
    new(-1, 1),

    new(0, -1),
    new(0, 1),

    new(1, -1),
    new(1, 0),
    new(1, 1)
};

Damn, useless comma at the end.

But, right, these are the 8 cells, where the cell checked has the offset (0, 0), and so (-1, -1) is its top-left corner

Should be called _offsets, actually

[fossil tree]

how can i check a vector position?

[willow scroll]

Check a vector position?

Not quite sure what exactly you're referring to

[fossil tree]

like how can i get the tag of my gameobject with a position

[gaunt ice]

Store it in a 2d array/sparse array/quad tree/ anything that can store grid

[willow scroll]

So you have a List of Cells, each contains the Cell's position in the grid and the reference to the e.g. GameObject

I just wonder whether these cells should be GameObjects..

But, right, they may

[fossil tree]

idk im suck

[unreal phoenix]

Are cells a class or struct?

[fossil tree]

i just go delete all and watch a A - Z game of life tutorial

[bold nova]

Does anyone know why raycast might not collide with game objects? I raycast from a gun and sometimes to goes right through the enemy... it is not about the layers, on the right you can see layers that are beeing ignored.

if (Physics.Raycast(rayCastOrigin.position, direction, out hit,
_weaponInfo.Distance, ~_ignoredLayers))
{
float magn = Vector3.Distance(rayCastOrigin.position, hit.point);
Debug.DrawRay(rayCastOrigin.position, direction * magn, Color.cyan, 3f);

var trail = SetUpTrail();

StartCoroutine(SpawnTrail(trail, hit));

DealDamage(hit);

}

[unreal phoenix]

You don't pass layers to ignore in a raycast, you pass layers to collide with

[brazen vault]

Hello guys so I just wanted to make a new game that will be happening in first person. I saw that Unity had a template for first person, so I thought I would use that. Everything works fine unless I started adding UI. So the template already offers the option to click ESC to freely move the mouse. But as soon as you click on a UI button, the mouse gets locked again. I tried to fix it, but I am pretty new at scripting, which is also why I use this template, and at some point, after spending a whole day going through so many scripts, I gave up.

[bold nova]

no, you can , if you write tilda sign before it

[unreal phoenix]

A bit of a weird thing to do but you could also add QueryTriggerInteraction.Collide

[gaunt ice]

why your draw the ray only if you hit it

though it cant solve yur problem but help to you debug

[bold nova]

well, i have an arena/ level with only closed space, so i didn't think it makes much of a difference since distance of raycast is set to 200

[unreal phoenix]

Have you tried doing a Debug.DrawRay with the raycast to verify the line is correct?

[gaunt ice]

but now you want to know why your ray doesnt hit anything

[bold nova]

Raycast always hits something, the problem is, for some reason sometimes it ignores enemies, here is perfect example. The blue line you see is a draw ray from a gun to a hitpoint. So it shows the whole path of a bullet, two shots go right through the enemy, so raycast didnt collide with enemy (he was standing idle) but the third one did collide and hp bar reduced a little, though you cant see it on screenshot

and scince raycast hit enemy once its not about collision layers

[willow scroll]

The Cell was a record in my case

[unreal phoenix]

Have you tried doing Debug.DrawRay right before your raycast to verify the data that you are feeding to the raycast?

[willow scroll]

But in their case, it may, probably, be a class. Though it doesn't matter, it can also be a struct.

[gaunt ice]

i would let the raycast able to hit anything first then check the layer of target to debug

or just check the layer of the yellow capsule in inspector and its collider

[willow scroll]

I would suggest you try out the Conway's Game of Life on Exercism, in case you first want to know how to implement it with a simple matrix. Should be a bit easier than doing it in Unity right away.
If you don't want to solve it, you may also try out my solution for this task or the solutions of the others. In case you want to use mine, I may assist you with its further implementation in Unity.
I'm not sure whether the links work as expected, so let me know.

The difference is that, instead of a matrix, which lets you access the cell's row and column, you'll, probably, want to use a List with the positions, which are not necessarily in a rectangle form.

Enumerating through every list's cell and checking the cells in the 8 directions shouldn't differ too much

[gaunt ice]

https://leetcode.com/problems/game-of-life/description/
curious if leetcode has game of life...and they have it
see how the leetcode problem passes the cell

[fossil tree]

i find a good tutorial in youtube for make it with tile map so go try

[willow scroll]

I like Exercism more through 😉

[willow scroll]

Alright, you may also try this out

[fossil tree]

idk if youtube tutorial are the best way to learn but i gonna try

ty for the help btw

[willow scroll]

Could you send it?

[fossil tree]

https://youtu.be/MB43Sd0xJUE

[willow scroll]

Oh, right, I haven't considered that you could have a simple rectangle game field

So a matrix can be usable in this case

[primal jungle]

Hoping someone can help me figure this out. I've got a fade-in/out transition setup to happen between scenes. It's currently doing this via a LevelLoaderController class (shown in the screenshot).

When the user clicks the "Play" button on the main menu, it works flawlessly.
However, on the next scene, when the user pauses and selects "Quit" it doesn't do anything (the quit button worked fine before introducing these transitions).

I've debugged it a bit and can see that when I press the quit button, it reaches the yield statement but then doesn't ever go past that.

[languid spire]

At a guess, whichever object which is starting the LoadLevel coroutine is being destroyed

[primal jungle]

How could I tell if that was the case? Would it disappear from the hierarchy during a test play? If so, nothing like that has happened.

Also, when debugging, it hits the yield statement and doesn't continue past that but, if I click the quit button again, it keeps reaching the same point and never getting past the yield (or starting any animation)

[languid spire]

you could add an OnDisable method to this script with a Debug in it to see if it fires

also the script where you start the coroutine

[primal jungle]

Will check, 2 secs

Have added the OnDisable method in my PauseMenuController (where the corouting that's not working is being called) and nothing was being output to the log

[languid spire]

try running the coroutine on the levelloadcontroller not on the script with Quit

[primal jungle]

Same thing :/

[languid spire]

just to be sure change your string variable from Start to start

it's odd to have a variable the same as a method

I presume this is a DDOL object

[primal jungle]

The trigger is named "Start" but Rider made the suggestion to convert it to a variable instead 😛

I've changed it from the int variable to the string "Start" but still has the same behaviour

The object is a prefab that's loaded onto both scenes which, on scene load, plays the fade-in animation automatically. That gameobject also has the LevelLoaderController script attached to it

Which is then supposed to play the fade-out animation on scene change

[languid spire]

but it needs to be DDOL otherwise it will not survive scene unload

[primal jungle]

Can give it a try. How do I set it to a DDOL object?

[languid spire]

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

[primal jungle]

So this should be fine?

Now the second scene doesn't load at all 🤣

Fades to black and then never fades in the next scene from the main menu

[wintry quarry]

What's in the animation

[queen adder]

I think is should ask here so is there a script where you can push a button and opens a door but the door only opens for you? cause I've been trying to do that but I cant

[wintry quarry]

Also are you changing time scale at any point

[wintry quarry]

What does "only opens for you" mean?

Is this a multiplayer game?

[primal jungle]

Yes... on the pause screen... 🤣 I think I'm starting to know where the problem is

[queen adder]

ye

[wintry quarry]

In general scripts don't just exist for your particular nuanced use case. You have to write them.

[queen adder]

aw man

that will probably be hard but I'll tey

[wintry quarry]

Use WaitforSecondsRealtime

[languid spire]

and, if you are even considering doing multiplayer you shuold know simple stuff like this already

[wintry quarry]

Yeah, code-beginner + multiplayer is usually a disaster

Multiplayer is not a beginner subject people

[queen adder]

eh it's turning out pretty well for me

[wintry quarry]

Least of all networked multiplayer.

[languid spire]

it's not even a 'general' subject, very much 'advanced'

[primal jungle]

Thanks. It's working better now in the fact that it switches scenes but doesn't do the fade out (presumably because the timeScale is set to 0 (?)

[languid spire]

that will be it

[primal jungle]

Is it possible to make the animation play irrespective of the "world time"? Similar to the WaitForSecondsRealTime?

[languid spire]

coroutines, like Update do not run when timescale=0

[primal jungle]

Managed to sort it by changing the update mode to Unscaled Time

On the animator

Cheers for the help both 👍

        }

I dont think im doing this correctly. I'm trying to implement balloon knockback by using animation curves, but if i set the value above 1 the player gets launched instantly as i'm assuming its just multiplying by 2 over and over again

@wintry quarry i'm trying out what you mentioned last night, idk if this has been done correctly though

[summer stump]

You have the Cellule class inside the Build class. Why?

[toxic hawk]

Buttons in unity could exist only on UI level, so if I want to make button on one of my sprites, I should either make anchor and follow on UI layer, or write custom script with button-like logic. Both ways seems very awkward to me.

Am I missing something?

[summer stump]

There are world space canvases

[toxic hawk]

But this would ruin my hierarchy, so I kinda still obliged to use anchor to connect sprite and button..

[summer stump]

How would that ruin your hierarchy?

[toxic hawk]

Button will be part of the other branch in the hierarchy

Unless I do mini-canvas for each object that uses it

[summer stump]

Yeah, each thing that needs a button would have their own canvas as a child. Then enable and disable them as needed

[toxic hawk]

That makes sense, thanks!

[stuck palm]

how can i reduce velocity with an animation curve ?

[summer stump]

Multiply the direction you want by the return of evaluating the curve (also multiplied by a speed factor)

[wintry quarry]

Should be setting the magnitude of velocity with this, not multiplying

[stuck palm]

i cant set magnitude, though

magnitude has no setter

[wintry quarry]

You set a float

And use that as the magnitude along with a direction from elsewhere

[stuck palm]

where would i get the direction from?

the only thing i can think of is the velocity of the rigidbody

[wintry quarry]

Whatever direction the player was smashed in?

[stuck palm]

but what if they hit a wall is the issue

[wintry quarry]

Then you stop

Or you bounce them

Or slide them along it

Whatever

Smash bros characters bounce at a certain threshold

[stuck palm]

would i have to manually calculate the bounce direction?

[wintry quarry]

I guess? These are all implementation details for you to figure out

Nobody ever said this would be simple

Vector2.Reflect exists though

[stuck palm]

this reminds me of my old system 😭 i'll experiment with this

[buoyant finch]

hello I want to make an attack I have 2 meshes for it and want to do it such that when Q is pressed the attack mesh is switched to from the standing mesh pls help

[willow scroll]

You have already been answered. Why do you cross-post?

[final totem]

should i use trigger or bool in the parameters of the animator for transitions? can i untrigger it? if then whats the difference with bool?

[polar acorn]

A trigger parameter is basically a one-time-use boolean. It unsets itself whenever it's used for a transition

[kindred nest]

trigger is like a flash, a signal for a single tick, bool is constant until you change it

[final totem]

mmm gotcha thanks guys

[final totem]

ive seen the on any state being used but whats this one for?

[deft grail]

to stop playing the animation after its done

so you can play it just once

[wintry quarry]

transition to it and no more animations will be playing

[fringe plover]

Decompiled my own code for some reasons, and saw this..

[final totem]

can i go back to other state or its forever?

[fervent abyss]

hey guys, i have a class which contains a string and a list of strings, and a list of that class:

[field: SerializeField] public List<ownedItems> OwnedItems { get; private set; } = new();
    [Serializable]
    public class ownedItems
    {
        public string CatalogName;
        public List<string> ownedItemNames;
    }

how can I foreach check OwnedItems list, if it any "CatalogName" inside of it contains a specific string?

For example theres 7 of these classes created inside the list, how can i check if any of them is equals for example to "Skibidi"

my brain isnt working for 2 days

[wintry quarry]

foreach (ownedItems oi in OwnedItems) {
   if (oi.CatalogName == "Skibidi") // do something
}```
simple no?

or using Linq:

bool anySkibidi = OwnedItems.Any(oi => oi.CatalogName == "Skibidi");```

[fervent abyss]

holy ducking shit i didnt think of putting ownedItems

brain is not braining

thanks

[wintry quarry]

what else would you put...?

that's the type of the obejctyou want to look at

[fervent abyss]

i just got confue

[wintry quarry]

well

your confusion is probably stemming from the fact that your variables are named poorly

And you're not following C# naming conventions

[slate haven]

I have made 2 games originally, and other games by following tutorials since 1 year. Yet I have to look up on google again whenever I want to start coding. Like if i want to create input method, I will have to look again on the internet to remind myself that this is how we do it. How do I fix this ( I want to remember all these by heart)

[rich adder]

repetition is key

doing it once or twice ain't gonna cut it

You have to consistently do it eventually it just becomes "muscle memory"

[slate haven]

yeah

guess i have to make more games without watching tutorials

[rich adder]

I mean you dont have to make an entire game just practice those functions together lol

[slate haven]

haha yes yes i get u

[chrome tide]

does unity have a built-in function that would allow me to check via code whenever an object is illuminated by some source of light? I'd like to check if there is any light on it.

[rich adder]

its not that cut and dry no

believe me, when I started had to do this exact thing because I wanted a spotlight to act as an enemy alert system

really depends how accurate you want to be and what you're doing thre are several workarounds

[chrome tide]

i wanted to create a hostile creature that would stalk the player but it would be afraid of light so it could be startled by a player's flashlight etc.

would raycasts be accurate enough?

[rich adder]

raycast could work but if its a flashlight you might need a bigger shape like a sphere or something

SphereCast

[chrome tide]

ok, thanks for the overall idea of how i could get that to work. i will try this someday

[rich adder]

yeah physics cast is def the way to go if you want something that works and is simple

[chrome tide]

fine, thank you

    }

}```

@rich adder

[rich adder]

whats the problem?

[sour jungle]

So when my player character goes below -5 it succesfully dies but when i click on the menu button the next scene does not succesfully work due to timescale still being 0

[barren vapor]

Basicly the game is stuck cause the game is paused

[sour jungle]

also when putting for example instead of (player.transform.position.y < 5) a keypress the whole thing does work

[rich adder]

switch it back to timescale 1 when you change level?

[sour jungle]

yes due to my character constantly being killed

[rich adder]

well why are you doing it eveyframe

just do

 if (Player.transform.position.y < -5 && !PlayerDead)
            {
                PlayerDead = true;
                Time.timeScale = 0f;
                Dead();
            }```

what is even the point of the if statement after

[tawny bolt]

can someone explain the problem with my script basicly i am supposed to take damage when i walk inside a box

[summer stump]

Like in real life, we must verify our existance every moment to avoid falling onto an existential dread we can never recover from. They are just thinking about their character's psychological state..

not player

or should i do opposite ?

[summer stump]

Put a debug before the if statement in OnCollisionEnter

[summer stump]

Well actually, yeah, the opposite makes more sense the way it is set up

[hallow sun]

what kind of collider does it have? maybe you need OnTriggerEnter instead

i dont see how you can "enter" it if its not a trigger

[tawny bolt]

will try that

[tawny bolt]

doing that now

[sour jungle]

like this?

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

public class Death : MonoBehaviour
{
    public static bool PlayerDead = false;
    public GameObject DeathScreenUI;
    public GameObject Player;

    void Update()
    {
        if (Player.transform.position.y < -5 && !PlayerDead)
        {
            PlayerDead = true;
            Time.timeScale = 0f;
            Dead();
        }

    }

    public void Menu()
    {
        Alive();
        Time.timeScale = 1f;
        Debug.Log("Menu");
        SceneManager.LoadScene("StartMenu");
    }

}```

[summer stump]

It just means collide. The frame you enter the collision

[summer stump]

No, do not just change things

Answer the question first

[tawny bolt]

ok

[summer stump]

What kind of colliders do you have?

[tawny bolt]

box collider

[rich adder]

did you try it

[summer stump]

They meant are they trigger colliders

[tawny bolt]

yep

[summer stump]

Well yes, it must be OnTriggerEnter then.

[sour jungle]

still stuck

[summer stump]

Which object has the rigidbody

[tawny bolt]

player

[hallow sun]

perhaps you forgot to give the player the tag? or a rigidbody?

[rich adder]

how are you calling Menu

[summer stump]

Ok, then the issue is that you cannot receive OnCollisionEnter when they are triggers

[rich adder]

what is stuck exactly

[summer stump]

Make the change they suggested

[sour jungle]

with a button

[rich adder]

is Menu log printing

[sour jungle]

the animation to the menu screen

[sour jungle]

yes

[rich adder]

well yeah animations dont work with timescale 0

[sour jungle]

exactly but buttons dont work either no?

[rich adder]

Time.timeScale = 1f; before doing any animations

[tawny bolt]

oki

[rich adder]

buttons should work fine

[sour jungle]

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

public class Levelloaderscript : MonoBehaviour
{

    public Animator transition;

    public float transitionTime = 1.0f;
    public void newLevel()
    {
        StartCoroutine(loadLevel(SceneManager.GetActiveScene().buildIndex + 1));
    }

    IEnumerator loadLevel(int levelIndex)
    {
        Time.timeScale = 1f;
        transition.SetTrigger("Start");

        yield return new WaitForSeconds(transitionTime);

        SceneManager.LoadScene(levelIndex);
    }
}```

still does not work

[rich adder]

you are changing timescale in all sorts of places

debug the value then

coroutines / animations dont work with timescale 0

so if its not working then timescale is prob still 0

[sour jungle]

so where should i put Debug.Log(Time.timeScale.value)?

[rich adder]

but you need logs inside to double check what Time.scale is when you press that

just Time.timeScale

is fine

[tawny bolt]

still dosent work

[summer stump]

Did you put the debug before the if statement?

[sour jungle]

    {
        Debug.Log(Time.timeScale);
        if (Player.transform.position.y < -5 && !PlayerDead)
        {
            PlayerDead = true;
            Time.timeScale = 0f;
            Dead();
        }
    }```

i put it here and in my console i am only getting 0's

[summer stump]

Did you move the script to the player? If so, did you change the tag check to check the other object instead?

[tawny bolt]

let me do that

[summer stump]

The debug would be more helpful at this point

[tawny bolt]

ok

[rich adder]

ok so your other functions aren't running

[sour jungle]

probably

[sour jungle]

if i remove the Playerdead = false at alive it works

[rich adder]

oh you were setting it back to false?

[summer stump]

You should remove the whole alive method.
Just do that stuff in Awake

[rich adder]

that makes sense.. you created a loop

[sour jungle]

yup very beginner

[rich adder]

huh I didnt even see that in Alive()

[sour jungle]

But now when i have died once and go back into the game i cant die anymore

[summer stump]

put that stuff in awake

[sour jungle]

i deleted awake

[tawny bolt]

got it working thanks

[rich adder]

^ that or make Init method

[summer stump]

Don't

[sour jungle]

So how should i fix that?

i reinstated awake

how should i set Playerdead to false again

[rich adder]

the same way you set it to true

what am i doing wrong?

[rich adder]

so are you certain the function is even running ?

[quaint mica]

I used a Debug.Log statement and yes it triggers

[summer stump]

Get rid of that if statement

Just set it false

[rich adder]

try with Impulse force instead

[sour jungle]

thats what it was breaking it in the first place

i tried and it does not work

[summer stump]

You tried that in Awake?

Or in Alive?

[rich adder]

how would that break anything

[quaint mica]

it still doesnt work

[rich adder]

its probably because you're overriding the player movement with velocity

[sour jungle]

this

[summer stump]

Yes, but that was not in awake

So completely different/unrelated

[rich adder]

can you show the current code and send it in a link

You were calling Alive over and over

    }

}```

this works once but then it stops working

[rich adder]

read what i wrote

send a link plz

[summer stump]

Because you don't set it in awake!

Just try it

[sour jungle]

Playerdead = false;?

[summer stump]

Of course

[quaint mica]

        Vector2 movement = position.normalized;
        rigidBody2D.MovePosition(rigidBody2D.position + movement * speed * Time.deltaTime);

This is the only other code affecting movement the posistion is from Input.GetAxis(Vertical/Horizontal)

[sour jungle]

doesnt work

[summer stump]

It will. Show what you did

[rich adder]

why are you using MovePosition?

did you make rigidbody kinematic

[sour jungle]

public void Alive()
{
PlayerDead = false;
DeathScreenUI.SetActive(false);
Time.timeScale = 1f;
}

[summer stump]

Oh my god. Do it in Awake

You've been told this a bunch of times

Not Alive, Awake

[sour jungle]

which awake?

like void Awake?

[summer stump]

Awake is a unity method that is called automatically

[sour jungle]

im so sorry

[quaint mica]

I don't think so should I put it in the start function

[summer stump]

Yes. Void is a return type

What's the name of changing rooms via "doors" on a 2D Plateformer game (like Celeste and Hollow Knight) ? I'm looking for some kind of tutos on the internet but no idea how to search for them.

I explicitly said "not in alive, do it in awake" 🤣

what does that have anything to do with what i asked

[quaint mica]

To make the rigidbody kinematic

[rich adder]

is the rigidbody kinematic or not ?

[sour jungle]

whew it works

[quaint mica]

It is

[rich adder]

then how do you expect AddForce would work on a kinematic ?

[sour jungle]

thanks @rich adder @summer stump for the help and patience with my feeble coding skills

[summer stump]

All good! Glad you got it

[quaint mica]

I changed it but it's stil the same

[rich adder]

you changed what?

[quaint mica]

the kinematic to false

[rich adder]

are you just randomly doing shit expecting a different result without understanding why?

MovePosition is meant for rigidbody kinematic

it overrides any forces, of course Adding force won't work

[quaint mica]

so before adding the force I can set iskinematic to false and after I can turn it on again to let the player move?

[fringe plover]

https://hatebin.com/annfkevskk
I need help, it says that there is no file and created absolutely same file...
Application.persistentDataPath + /settings.json is path

[summer stump]

You would also have to stop calling MovePosition during the addforce

[rich adder]

that will be cumbersome because you cannot use MovePosition every frame to AddForce

[summer stump]

All of that code after the if will run no matter what

That should all be in else

[muted forge]

Hi

[summer stump]

Or return inside the if statement

[quaint mica]

Is there another way to move the player around without MovePosition, should I use transform.position instead?

[summer stump]

Definitely not

[rich adder]

not at all

[rocky gale]

Use rigid body or character controller

[fringe plover]

wait... i forgot.. ok thanks

[summer stump]

Use velocity, addforce, or moveposition

[muted forge]

Can some one tell me what the uses of comment in python

[summer stump]

This is a unity server. So that is off topic

[rocky gale]

[muted forge]

Actually I'm newbie

[rich adder]

anyway this isn't a python server

[summer stump]

Not the issue

[muted forge]

So don't know much about this

[rocky gale]

Commenting uses is to comment

[rich adder]

comment the reasonning of why you are using a function for example

don't comment what the function does, cause it should be obvious without comments

[muted forge]

Ohk thanks bro

So which code is used in unity

[rich adder]

c#

[muted forge]

Ohk

Thank you so much

[willow scroll]

Why?

[rich adder]

its not a set rule just an opinion, I mean obviously do whatever is easy for you but I never had to comment what a function does because it pretty self explanatory to me

but at times I do have to comment the reasoning behind the function

[willow scroll]

I mean, this may be self explanatory in some cases, but you might want to add a summary for someone using this method

But I'm not sure whether you include <summary> in your assumption

[rich adder]

sometimes I do summaries sure. Depends if the code will be shared mostly

if i have CalculatePath method, I don't think the summary is required, then I'm just writing sugar

I've finally resolved my issues with mercy invincibility - turns out they collided with components with the default layer

How can I Attach a point light to a Player?

[finite dew]

easiest way, would be to create a point light gameobject, add it as a child of the player gameobject, and move it to a spot relative to the player from where you want it to shine

[shell gorge]

Ooh ok

How to add it as a child in the character? I have the point light ready.
