[polar acorn]

Unity sends messages to all MonoBehaviours to run functions that match the message signatures, such as void Update() or void OnCollisionEnter(Collision other)

[serene acorn]

Like, they are the base components for unity; you can download extra components from the store but they ate made by other guys

[serene acorn]

Yeah, they have like keywords, special words reserved for some premade methods and variables I suppose

[wooden socket]

this is 2 different lines right

[serene acorn]

It was weird to me that's all

[polar acorn]

They're not "special" or "reserved". There is a line of code in Unity that says "Loop over every game object, then every component on it. If it has a function named Update that returns void and has no parameters, call it"

It's just a normal function

You can freely call someBehaviour.Update() just like any other function

[serene acorn]

Reserved in the sense that I can't make a custom functions named "Update" because unity already has a meaning for that word

[summer stump]

I mean, you certainly can

Especially if you make it an overload

[polar acorn]

You absolutely can. In fact, you always do. It's just that Unity will call that function every frame

[summer stump]

You likely do not WANT to though, if you expect it to act differently

[wooden socket]

are the blanks all ToString?

[serene acorn]

That's the thing, it has special privileges then

[polar acorn]

Every Update is a custom function for that script. It's not calling anything. It gets called

[serene acorn]

If I wrote BizarroUpdate it wouldn't work the same

[polar acorn]

It's not special privileges. It's just that Unity calls it

[summer stump]

That is what I meant by using reflection

[rich adder]

no because its a different function not matching signature.

[summer stump]

It checks the actual name of the method

[polar acorn]

Correct. But if you made a different script that scanned for functions named BizarroUpdate and ran them, you could do the same thing

It's nothing "special" that Unity does. It's a thing that anyone could do

[serene acorn]

But what's what I'm saying, nevermind

[long jacinth]

my whole game started rotating lol

[serene acorn]

But it does by default

[raw token]

It's an inherited member which you're overriding. It already has a defined a purpose, but in no different manner than how inheritance works in other classes

I eat my words - it's not inherited 😅

[serene acorn]

Like I don't have to setup anything for it to detect "update"

[wooden socket]

okay ill put it in an update field

[summer stump]

Correct 🤷‍♂️
That is what an API is

[polar acorn]

Right, Unity has some messages that it will call. I sent you a link to every message function Unity uses and when it calls them

[rich adder]

its just a Method from the Parent class

[serene acorn]

Yeah yeah I get it

[polar acorn]

but they're completely ordinary functions, that are called via reflection by a script that is run by Unity

[long jacinth]

i think i messed up one second

[serene acorn]

It's logic already made by monoBehavior

[rich adder]

there is no logic in it

[wooden socket]

i filled out the blanks and it still didnt work

[ivory bobcat]

This is a common pattern that'll be found with many frameworks and libraries.

[summer stump]

Or, in the case of OnCollisionEnter, rigidbody and collider

[rich adder]

it just calls the C++ backend

[wooden socket]

int score = ScoreManager.instance.score.ToString();

    displayText.text = Score.ToString();

[polar acorn]

There's no "ur-Update" function that everything's "inheriting" from. It's not defined anywhere. It's simply checking the name, and executing the function, whatever it does

[serene acorn]

i suppose I could in theory do a bizarroMonobehaviour script, copypaste the code and would also work

When si inherit from it

[eager spindle]

very close actually

[rich adder]

this errors in the IDE

[wooden socket]

i also just made the score lowercase bcs thats what u suggested

[polar acorn]

ScoreManager.instance.score.ToString() means "ScoreManager's instance's score's String Value". int score = means "Create a variable that holds an integer, and set its value to"

Put together:
"Create a variable that holds an integer, and set its value to ScoreManager's instance's score's String Value"

Does it make sens to store a string value in a variable that can hold an integer?

[long jacinth]

https://gdl.space/hunejeduti.cpp this is my code as you can see its a pivot gun i literally just want the gun to move up around when i shoot it

but unfortunately when i try it doesnt work

[wooden socket]

okay so I combine int score = ScoreManager.instance.score.ToString()

i thought it was 2 lines

[eager spindle]

either works but pretty close

[polar acorn]

That's literally the line I just broke down for you

[eager spindle]

for int score you're not using an int anymore though

change it accordingly

[wooden socket]

and this all goes in an update

okayuu

[serene acorn]

That's what I quite don't get

Like for example

[rich adder]

you need the scoretext to update every frame ?

[eager spindle]

its more for convenience purposes, this wouldnt fly inother codebases

[eager spindle]

let them cook

save us sanity

[serene acorn]

Let's say with boxcollider2d

[wooden socket]

no it goes in awake

[rich adder]

well its good for them to at least somewhat know what Update is doing

[serene acorn]

Wdym, so it's just monoBehavior acting like a shortcut for stuff

[wooden socket]

okay it doesng go in awake

[rich adder]

Awake runs once when object is created, Update runs every frame

make your decision

[eager spindle]

yea ig, at the endo f the day unity is still a c++ codebase and the tools are just a C# interface to their binaries

[wooden socket]

wait but it didnt work in Awake

i still get errors

[eager spindle]

it works in awake, just only once. it wont update again

[polar acorn]

It's not. It's just that the code that scans for the function will scan any objects of type MonoBehaviour. There's no definition inside of MonoBehaviour that says "This thing has an Update function". There's code that says "If this thing is a MonoBehaviour, and it has a function called Update, call that function"

[polar acorn]

What do you have and what are the errors

[rich adder]

if you have errors thats why it doesn't work

[serene acorn]

Pffff I'm not getting it, let me make up my mind...

[rich adder]

we need to see what u wrote

[polar acorn]

Okay, so, first error: What's scoreManager

[wooden socket]

its my other script

and a class i made

that houses the public static ScoreManager instance

[rich adder]

yes but that script doesn't know what it is

[wooden socket]

but i already have a public static score manager instance in my scoreManager script

[rich adder]

so why do you have scoreManager still in there in UI script if you already have ScoreManager.instnace

[polar acorn]

Okay. Show it

[wooden socket]

https://gdl.space/ixayusicon.cs

[rich adder]

did you save first of all

[wooden socket]

yes

[rich adder]

why is it complaining scoreManagement.cs but your class is called ScoreManager

[wooden socket]

managment is the name of the file

[rich adder]

you should keep your names the same as class with filename

[wooden socket]

ok

[summer stump]

You said you are not a developer, right? How much handson experience do you have with coding? I feel like all of this would be very confusing in abstract, but make much more sense when actually implementing it.
I am simply not sure how to explain it in a way it makes sense. Other than repeating that these are magic methods and used via reflection.
Sorry

[polar acorn]

No that's ScoreManager I asked what scoreManager was

[serene acorn]

I know how to programm in csharp

i mean im junior but yeah

brb let me write a long message about what confuses me

[wooden socket]

public class ScoreManager
{
public static ScoreManager instance;
public int score;
}

[long jacinth]

how can i just add to the Z rotation value

[eager spindle]

you can add a Vector3 with the x and y values set to 0

[rich adder]

thats not the scoreManager its complaining about

[rich adder]

get rid of scoreManager

capitlization matters

[eager spindle]

you dont need to set scoreManager's score. in fact scoreManager doesnt exist. only ScoreManager.instance

[polar acorn]

What is scoreManager

[wooden socket]

okay so nwo there are two scores

[eager spindle]

MY UNITY CRASHED

MY SCENE NOO

[rich adder]

you can still recover if unity isnt opened again

[polar acorn]

You can recover it if you don't reopen unity right away

[wooden socket]

heres whaht I got

wait

[rich adder]

ok so now what is score

[wooden socket]

shit i made mistake

score should be whats in Awake

[rich adder]

get rid of start completely

[wooden socket]

none

did it

[eager spindle]

score doesnt exist because you havent defined it yet

[rich adder]

what happen to text

[eager spindle]

you dont need score either

[rich adder]

stop showing ScoreManager

[wooden socket]

ykw gimme a sec

[rich adder]

we dont care about ScoreManager

[polar acorn]

Yes this is all correct

this is fine

that's not the issue

[wooden socket]

https://gdl.space/ahotowisic.cpp

[rich adder]

oh lord

why is this defined in here..

public class ScoreManager
{
    public static ScoreManager instance;
    public int score;
}```

[wooden socket]

okay ill remove it and put it in the other script

[rich adder]

who told you to put it

[eager spindle]

not a monobehaviour either

put it in seperate scripts

[wooden socket]

so I make a new one

or put it in scoreManagment

[rich adder]

can you please stop and think for a moment..

dont touch anything on the ScoreManager everything was fine on how you had it

[wooden socket]

okay new script

like entirely new

[eager spindle]

is it spoonfeeding if i make a whole video tutorial on this right now

[summer stump]

No

[rich adder]

You need ONLY 2 scripts. you got that part or not

[wooden socket]

OKAY

[rich adder]

no "new script"

[wooden socket]

ok

[rich adder]

if you're struggling with simple following instructions might wanna give another hobby a try

[wooden socket]

i put public class ScoreManager
{
public static ScoreManager instance;
public int score;
} in the displayScore script

[polar acorn]

Okay, I am going to say some pretty harsh things but you are going to need to hear it.

If you are incapable of basic logical reasoning, you will never be able to code anything at all. You need to actually think through what you are doing. These lines all have meaning. They say things. You need to be able to hold multiple statements and draw conclusions from them. This is not something we can teach. This is not something anyone can really teach. If you are incapable of logical reasoning, this is not the hobby you should be pursuing. You will not create any programs by randomly bashing words into various places until they stop yelling at you

[wooden socket]

dude what the hell

im sorry

im just very tired

im trying really hard

im really sorry

[rich adder]

My dad used to say "Dont be sorry just do it correctly"

[polar acorn]

I don't intend to be mean, I just want to warn you

This seems like a failure to connect cause and effect

which is going to make this very very hard for you

[wooden socket]

this is just very rude

okay ykw besides the point

[rich adder]

just being honest

[wooden socket]

in diisplay score I put

public class ScoreManager
{
public static ScoreManager instance;
public int score;
}

[ivory bobcat]

I'm just going to provide a solution as this is likely a guessing game that isn't really productive for the server channel cs private void Update() { scoreText.text = ScoreManager.instance.score.ToString(); }Which will likely not work properly if they do not have an appropriate Singleton object instance in the scene.

[eager spindle]

you can try hard but without the foundational knowledge you wont be able to get far. learn object oriented programming first and develop stuff with it. learn what static variables are, what types in c# are, and learn unity's quirks. what MonoBehaviour is, what Start, Awake, Update and LateUpdate do

[rich adder]

this isn't a coding this at this point, you arent even following our instructions correctly

[wooden socket]

earlier you told me to remove it. and now I only need 2 scripts?

[rich adder]

you're just guessing and writing stuff that dont' need to be written in code

[summer stump]

I think the steps of operation may help? so Physx or Box2d checks the position of every collider every physics update.
If some overlap, it will tell unity.
Unity will iterate all monobehaviours with those colliders and check if conditions are right for the physics message to be sent. Then it sends the message to the methods providing data for you to use in your code. Because of course the only place you COULD use it is in your own code (ie, a MonoBehaviour)

[wooden socket]

you are very confusing

[eager spindle]

because of the way MonoBehaviour is, ScoreManager and displayScore must be in different files.

[polar acorn]

No, you just don't seem to be able to synthesize multiple statements into one conclusion

[wooden socket]

they are

[rich adder]

and write something completely different than what was said or shown

[polar acorn]

"I need ScoreManager to exist" and "ScoreManager should not be in the same file as DisplayScore" should lead to the conclusion "ScoreManager should be in a different script" without having to be directly told that

[eager spindle]

and ScoreManager isnt a monobehaviour either, based on what you showed us. Because ScoreManager is not a monobehaviour, you couldnt set public static ScoreManager instance to the ScoreManager because there's no start function.

Because of that, theres a null reference. And thus your code didnt work out

That's not factoring in you having difficulty converting an int to a string.

[serene acorn]

https://docs.unity3d.com/ScriptReference/Collider2D.html

for example, here, this is a component, a collider. It has properties, and it has functions, something like

void Start()
{

    mycollider = GetComponent<Collider2D>();

    mycollider.enabled = false;
    mycollider.enabled = true;
    mycollider.IsTouching(mycollider);
}```
here it has functions exclusive to that component, like "Istouching" and it has properties/functions that are common through all components, like "enabled" (all ccomponents can be enabled/disabled)


My question is, why doesnt it have something like```mycollider.OnCollisionEnter();``` because if I put this I get an error. 

I suppose many collider components have a common parent, component, called "collider" it seems, for what I'm seeing here on the docs. But my question remains, why cant I get the "check if it has collided" function directly from the collision component?

@summer stump

@polar acorn

[rich adder]

where are you getting that from ?

[serene acorn]

dunno If I explained it right

[eager spindle]

Overall, you should understand that unity requires knowledge of object oriented programming, and the ability to search online for what you need to do

[polar acorn]

Because Collider2D does not have a function named OnCollisionEnter

That is not a member of that class

[summer stump]

You would be CALLING a method doing that.
You want it to be called BY the physics engine though

[polar acorn]

it is a message function that is called by collisions

[wooden socket]

damn it man

just tell me where this ONE thing goews

goes

[ivory bobcat]

On collision enter isn't a public member

[wooden socket]

its the final thing

[rich adder]

WE DID

[wooden socket]

we are so close please just

tell me

[polar acorn]

They did

#💻┃code-beginner message

[wooden socket]

no, you just told me to fill in blanks and after I did i was very close apparently

[polar acorn]

They wrote the whole damn class for you

[eager spindle]

"git good" would be too harsh. its more of "learn the foundations". you had difficulty converting an int to a string which is one of the first things taught in c#

[rich adder]

thats whats even more frustrating we didnt even hide behind the bush or hint at it. We literally give you lines of code to copy
and you still copied wrong

[wooden socket]

oh i didnt see that

[summer stump]

Well at least with Collider it seems to be a member?
https://docs.unity3d.com/ScriptReference/Collider.OnCollisionEnter.html

[serene acorn]

yeah I suppose it doesnt work because it doesnt have that function, but why doesnt it have it?

[polar acorn]

You were literally given the exact line of code to use multiple times and copied it wrong

[polar acorn]

Because what would that function even do

[serene acorn]

isnt that what we want?

[wooden socket]

this is in scoreManagment

[summer stump]

No, definitely not

[serene acorn]

check if the collider has collided right?

[wooden socket]

oh wait

hold the phone

[polar acorn]

What is scoreText

[serene acorn]

so whats what im not getting

[summer stump]

You want to be informed that it happened, not check it yourself

The physics engine is checking it

[wooden socket]

well

lemme test it now and see if it works

[polar acorn]

That sounds like IsTouching which does exist

[wooden socket]

i fixed the errors

[serene acorn]

like, start, update, on collision enter... all of those are functions right?

[polar acorn]

yes

functions you make

[summer stump]

Yes, and YOU are not calling them. Unity does

[serene acorn]

yeah I suppose

[wooden socket]

okay it works

[polar acorn]

they are called by unity. Not made by unity

[raw token]

They're more like event handlers

[eager spindle]

the way messages work is that youre calling a function by the function name. it quite literally looks for all objects with the function named "OnCollisionEnter`. you're not overriding a function. youre just hoping the physics engine finds your gameobject with the OnCollisionEnter function,

thus you need to define the OnCollisionEnter in your gameobject first.

[wooden socket]

everything works

okay wel

well

im gonna take a break for 2 days

goodbye

[eager spindle]

[eager spindle]

this example doesnt define OnCollisionEnter yet so thts why it doesnt work

[summer stump]

That would certainly be nice. And they are LIKE it. But it is reflection

[serene acorn]

yeah I get that unity is searching for a function of that name

[serene acorn]

thats what I dont get

let me think how to say it

[eager spindle]

the physics engine looks through all monobehaviours, checks if it has OnCollisionEnter, then acts upon it

[polar acorn]

OnCollisionEnter is a way of saying "Hey, physics engine, can you let me know when someone crashes into me? Thanks"

It wouldn't make sense for it to be a function you call on a collider

[summer stump]

Defining OnCollisionEnter is like that!

[polar acorn]

Because you don't know when a collision happens

[summer stump]

Not calling it. Just to be clear

[polar acorn]

Unity does

Unity needs to tell you when a collision happens. So you define a method that runs when Unity says "Hey, you hit this thing"

[serene acorn]

yeah I get that unity is checking the monobehaviour scripts and looking for those keywords and act uppon it. What I dont get is why cant oncollisionenter be exclusively inside the collision components

and not something outside of it

[serene acorn]

but you do, when the gameobject has another gameobject in an area right?

[eager spindle]

you only know about it because unity told you about it

or rather, the physics engine

[polar acorn]

Okay, and how would you know when that happens without asking the physics engine about it?

[serene acorn]

so it all falls down to the physics engine?

[summer stump]

What is "in an area"?
You do not know that unless doing manual physics checks, or letting the physics engine do it for you

[eager spindle]

yes, physics is completely seperated from everything else

[summer stump]

Yes

It is a completely separate engine

[serene acorn]

ok I think im starting to get it now

[polar acorn]

You absolutely can do the math yourself in update and keep track of what is intersecting with what. In which case, you don't need colliders at all

[verbal dome]

Honestly this doc confuses me. Even the examples are demonstrating MonoBehaviour.OnCollisionEnter instead of Collider.OnCollisionEnter

[rich adder]

Collisions is physics

[polar acorn]

But, since you're using colliders, you probably want to know when that collider has collided

[summer stump]

Yeah, I am super confused by it too
There is one for Rigidbody too

[verbal dome]

I dont think that page should exist lol

[serene acorn]

ok so because collision is physics and are complicated operations, is not enough to have a check inside a component, you need unity, the engine, to act and thats why iOnCollisionEnter has to be separated

[eager spindle]

the library unity uses is called PhysX. for physics engines the overall procedure is

• add a bunch of physics objects to a scene(cube, sphere, mesh)
• keep calling Physics.Simulate(delta) to update the positions of your physics objects
• keep changing the position of your GameObjects to the position of your physics objects

[serene acorn]

imagine how it confuses me

[verbal dome]

Just ignore it 😄

[rich adder]

the physics is "sweeping through the area thats why it has to know about all objects

all the ones with colliders become part of that separate "physics scene"

[polar acorn]

Yes. That's the entry point to how you'd respond to physics. Imagine a mailman who runs letters between the physics engine and your script. You making a function OnCollisionEnter is kind of like setting up a mailbox for letters to be delivered to

[raw token]

Just because Unity did not choose to implement the API in that fashion. They totally could have exposed a public event on Collider that you could subscribe your own method to:

collider.OnCollide += MyCollisionHandler;

...but they didn't. They chose this reflection-based approach instead.

[serene acorn]

so basically when you do "oncollisionenter"iS the unity phisics engine what is managing all of that

[polar acorn]

I think when Unity started, C# didn't have event yet

[serene acorn]

and it can't be something outside of it, like a component

[verbal dome]

https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnCollisionEnter.html

[polar acorn]

Yes, the physics engine is the one that calls those functions

[eager spindle]

at the end of the day you need a Collider for OnCollisionEnter to work. internally, defining OnCollisionEnter could just be a shortform of adding something to Collider.OnCollisionEnter

[rich adder]

Unity uses PhysX to leverage the physics then it gives us the easy functions

[eager spindle]

we wont know what happens inside unity core

[raw token]

Ahhh that's really interesting. I hadn't considered that. The reflection always seemed strange to me, though I do appreciate it's convenience

[polar acorn]

There's a lot of technical baggage from Unity 1, which mostly used javascript, and later added C# support

[rich adder]

wasn't it its own language and not real js ?

[eager spindle]

yea it was js-like

[serene acorn]

I dont understand then why something like box colliders or rigidbodys are optional components then if the operations are made by the physics, why arent the same as the "transform" like all components have?

[polar acorn]

Yeah, unityscript. But it used js syntax

[summer stump]

You REALLY do not want all objects to be simulated by the physics engine

[eager spindle]

not everything needs a collider or rigidbody though

[polar acorn]

Because not everything needs to be physical

[serene acorn]

because for example sometimes I have components that I dont need them to be in a specific position in the map, something like a background song

[verbal dome]

But Collider does not have a member method called OnCollisionEnter. It's just wrong

[serene acorn]

why do they all have a transform component that you cant remove then?

[polar acorn]

An object might represent, for example, TurnManager, an object that knows whose turn it is and who's next and so on. This object doesn't really "exist" in a physical sense. It would not need a collider

[eager spindle]

what we code in C# versus what goes on in unity core in c++ is different

[rich adder]

gameobjects cannot exist without transform

and vice versa

[summer stump]

Because that is simply a position

[eager spindle]

maybe if you work in a corp that has unity source code youll get to see it all

[summer stump]

How can a gameobject not have a position (and scale and rotation)
It is not physics

[polar acorn]

Because the Transform is more than just "where an object is", it also defines an object's parent, and creates a coordinate space for any of its own children

[serene acorn]

yeah but a component could not have a position and be "everywhere" sort to speak, like a background song

[polar acorn]

An object could define a coordinate space but not physically exist, such as the canvas

[rich adder]

its in a physical world, so it needs to have position. Unity is Gameobject / component based

[eager spindle]

cant gameobjects exist without transforms in ECS?

[summer stump]

Not really

[serene acorn]

I suppose its the basis of how unity made teh components

[eager spindle]

you can just avoid using it

[verbal dome]

Even if it was a thing on the c++ side, why would the C# scripting docs have that?

[polar acorn]

Canvas objects are massive so that their coordinate space is in pixels instead of meters, but they cannot have physics on them

[eager spindle]

for me I have a Manager gameobject that has every manager script

[serene acorn]

yeah but... feels off

[eager spindle]

unity things

a lot of gameobjects do it that way too

[polar acorn]

So, a canvas does have a scale and position, because it's important where other objects are in relation to it, but it's not a physical object that can collide or be moved by physics

[eager spindle]

its better than changing your background music in the project settings

[serene acorn]

bu thats my point, canvas, music, things that dont have a specific place in map, at least like other objects

[serene acorn]

I will stick to this

[polar acorn]

I just explained how a canvas does need to have a specific place and scale, because it's something other objects define their positions relative to

[rich adder]

they are still contained on physical objects in the engine world (the components)

[eager spindle]

its easier to extend monobehaviour to do your things rather than add directly to engine code

[summer stump]

But they DO have specific positions

[eager spindle]

you do not want to spend 12 hours compiling unity

[serene acorn]

so basically collisions, physics and stuff like that are handled by unity directly and thats why it is on monobehaviour instead of inside a component

[ivory bobcat]

The common patterns are:

• You iterate through every object, validate them and do what you've defined them to do
• You'd just define and subscribe them (the magic portion)
  Unity (and many other frameworks and libraries) will likely opt for the second behavior as the first is less flexible (subscribe/unsubscribe), puts the burden on the person implementing/defining the function (manage-less) and requires the library to expose members. The purpose of events is to have users be able to subscribe/unsubscribe to stuff without knowing or being able to modify the stuff. The user shouldn't need to know or modify whatever's calling their code - decouples implementation.

[eager spindle]

monobehaviour is a component but better

[serene acorn]

yeah but they dont really need them as a concept I mean

[summer stump]

They do. Because the camera and listener can move.
If the canvas does not move along with it, it will go out of view

[rich adder]

more like a type of Component

[untold bear]

I have this scene which works fine in the editor but when building I get this parsing error , I went to look at the file in code and it looks just fine at those lines

[eager spindle]

whenever i put oop in layman terms I address child objects as "but better"

[serene acorn]

I meant in a broad sense, like if you wanted a background music for everything, independently

[eager spindle]

monobehaviour comes from behaviour coming from component

[summer stump]

Then it would have to be positioned at a static offset from the listener

[serene acorn]

differences between those? or is it not important?

[eager spindle]

not important just use monobehaviour

[rich adder]

major differences

[eager spindle]

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

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

[ivory bobcat]

They probably implement stuff or give features you use in the derived classes that you aren't aware of.

[serene acorn]

come on @eager spindle @rich adder you cant just put those two comments together

[rich adder]

Rigidbody is a Component but not a behavior iirc

[eager spindle]

theres big differences, but generally most people use MonoBehaviour

[rich adder]

hence why it cannot be disabled

[verbal dome]

Generally speaking, Behaviour is for built-in components and MonoBehaviour is for custom components

[serene acorn]

will not think about it at the moment then

[eager spindle]

yea this has proved to be inconvenient to me at times

some days I just want to disable rigidbody

but no i have to set iskinematic

[serene acorn]

just I should know that everything comes from monobehaviour

like oncollisionenter, start, update

and that unity determines which one goes first

[eager spindle]

everything you want to make comes from monobehaviour, yes

[rich adder]

you can turn simulation off in Rigidbody2D thats about it

[rich adder]

I wonder why PhysX doesnt have that

[ivory bobcat]

How would this be applicable for Scriptable Objects then 🥹

[serene acorn]

another thing, would it be possible that components didnt have transform as their base? like if you wanted an ephemeral component like music

[verbal dome]

Turn off gravity and disable rb.detectCollisions should do it 🤔
And maybe make it kinematic

[serene acorn]

like I suppose itsa just how unity made things, im just asking if its possible

[rich adder]

oh true. I usually make it kinematic, jus wondering why 2D one has a toggle and 3D we don't have a fancy toggle

[serene acorn]

dont confuse me please 😦

[eager spindle]

ScriptableObject inherits directly from UnityEngine.CoreModule.Object(not to be confused with System.Object).

MonoBehaviour inherits from Behaviour inherits from Component inherits from UnityEngine.CoreModule.Object

thats a tongue twister

[ivory bobcat]

They don't.. they just all have a property to access the Transform component.

[summer stump]

Not really, no

[eager spindle]

all monobehaviour wants a gameobject. and all gameobject wants a transform. so no

[rich adder]

Static classes on crank

[ivory bobcat]

Aye, so the dependency isn't with MB - my point.

[eager spindle]

yuh

[serene acorn]

oh yeah I suppose something like update is static

like how does unity detect which update goes first

from one gameobject or another

[eager spindle]

script execution order, otherwise theres no reliable way to tell

[rich adder]

no no . Scriptable Objecect I meant are similar to how static class work but with unity benefits

[eager spindle]

you can go to Project Settings to change that

[serene acorn]

thats what I wanted to know thanks

you read my mind

[ivory bobcat]

You don't worry about that and likely will not be able to do anything about that without changing the priority.

[eager spindle]

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

fun stuff

wait whats monomanager why is the page called that

[rich adder]

yeah if you're messing with executions order your design is probably flawed

[serene acorn]

ok so

[eager spindle]

my savesystem needs to go first

[eager spindle]

but other than that nothing else

[serene acorn]

collider is an abstract class then?

[eager spindle]

yep

[rich adder]

I just use Dependency injection for everything 🤷‍♂️ never need to worry about order of exec anymore

[ivory bobcat]

Why do you suggest that?

[summer stump]

I don't believe so, no

[long jacinth]

how

[eager spindle]

because a collider doesnt have a shape, its children do though

[serene acorn]

and I suppose these were made as default by unity devs

so these are tied to the physics engine in the end

[eager spindle]

transform.eulerAngles += new Vector3(0,0, angle)
🥣

[summer stump]

Abstract is a specific keyword

[rich adder]

these are Unity's representation of the Physx version

[eager spindle]

well you cant do anything on a collider with no shape

[ivory bobcat]

What I see is that Collider is where On Collision Enter is defined.

Like if you decide to define an enum in your class.

[serene acorn]

abstract means that you cant instantiate that directly right? like "vehicle", you cant instantiate, you can have a car boat, bus, but not a "vehicle" alone

[eager spindle]

you can GetComponent<Collider> but unity will tell you its outdated

[verbal dome]

Be aware that you can still make classes that don't inherit from MonoBehaviour or anything. cs public class MyClass { }
POCO or "Plain old C# object"
You just can't attach them directly as components, but you can have a reference to them

[long jacinth]

do i add recoil and angle together?

[serene acorn]

yeah I suppose a collider must have a shape

[eager spindle]

you cant make a new collider since the constructor is probably protected, youll need to talk to the phys engine instead. which is what unity does when you add a collider component

[eager spindle]

your recoil is the angle

[serene acorn]

yeah I can make structs and such

[eager spindle]

what does it mean to add the recoil and angle together

[serene acorn]

is just that they wont have the unity things

[long jacinth]

like this "Gun.transform.eulerAngles += new Vector3(0, 0, Recoil);"?

[eager spindle]

yuh

[serene acorn]

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

[long jacinth]

well it unfortunately doesnt work

[serene acorn]

so here messages arent quite right functions

[eager spindle]

why

well it rotates the gun which is expected

[serene acorn]

they are like "checkers"

[eager spindle]

did you mean to rotate the camera instead?

[long jacinth]

oh it does

[ivory bobcat]

That's true but probably not what he's questioning about as the image shown is of the On Collision Enter method #💻┃code-beginner message
Which implies that there's some misunderstanding about OOP (where a member lives etc)

[long jacinth]

theres a problem

its because the gun will always point to the mouse

i see it rotating for a millisecond

[serene acorn]

and I dont have to worry how the calling logic works because thats what unity is for, to manage that right?

are these all the messages unity has or are there some extra ones outside of monobehaviour?

[summer stump]

Basically. You cannot work with it directly without the instance inheriting from it.

[eager spindle]

https://docs.unity3d.com/520/Documentation/ScriptReference/Collider.OnCollisionEnter.html

one example I found. even in legacy docs, OnCollisionEnter for Colliders dont have its own page

[long jacinth]

how can i approach this

[eager spindle]

you want the camera to rotate, so get the camera's transform and do the same

or do you just want the gun to be offset?

[long jacinth]

offset ig

the cursor will anyways be invisible

[eager spindle]

• keep track of a Vector3 that's your offset.
• after you rotate your gun in the direction of your player, rotate it again based on the offset

[serene acorn]

wait what so there is this link https://docs.unity3d.com/ScriptReference/Collider.OnCollisionEnter.html

and this link https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnCollisionEnter.html

I suppose the collider one is residual

[long jacinth]

so maybe "OffSet = Gun.transform.eulerAngles + new Vector3(0, 0, Recoil);"

[verbal dome]

Yes, please just pretend that the first one does not exist

[ivory bobcat]

It's a common pattern and you'll only see more as you grow as a developer - most of the Unity Network libraries (not limited to this as well) will use said pattern.

[eager spindle]

i honestly think they might have been different functions at some point, got merged, but for "legacy purposes" they keep seperate docs for it

[long jacinth]

void FaceMouse()
{
Gun.transform.right = direction + OffSet;
}

[eager spindle]

its been > 10 years though

[ivory bobcat]

You'd just work with the docs

[serene acorn]

thats what confused me at the begginig because I read the ciollider link first and I was all confused

[long jacinth]

the function for the gun looking at the mouse

[verbal dome]

Yeah it doesn't help that the Collider one is the first one that pops up on google

[serene acorn]

so the "collider" class shouldnt have that function then. thats what I was refering to in the beggining XD like, why didnt they put oncollision into the collider and it seems like they did but they changed it

[eager spindle]

"unity things"

[verbal dome]

Make a class variable where you store the recoil.
Every frame after you set the gun's rotation, add this recoil vector to its rotation.

[verbal dome]

Even if you go all the way back to Unity 5.2 docs, it still demonstrates MonoBehaviour.OnCollisionEnter:
https://docs.unity3d.com/520/Documentation/ScriptReference/Collider.OnCollisionEnter.html

It's a weird decision from whoever documented it

[dusty shell]

RaycastHit2D hit = Physics2D.Raycast(transform.position, Vector2.down, 0.05f);

this casts the ray from the player position down but i'm worried if the distance is too small, also how do I use this to check if the player is colliding with the ground

[verbal dome]

You can use Debug.DrawRay to visualize the ray

[dusty shell]

I put this in the update?

[ivory bobcat]

Best to try Googling a tutorial and getting a working system first.

[verbal dome]

For the ground part, it's common to use the LayerMask parameter in Raycast where you pass the layers that you want to be checked. So the layers that "ground" objects use

But yeah, plenty of resources online about ground checks

[verbal dome]

FixedUpdate, unless you are using CharacterController?

[dusty shell]

yeah that's what i meant

[verbal dome]

Physics don't necessarily update between Updates, but they always do between FixedUpdates

[spare mountain]

'between' as in FixedUpdate always runs after a physics update?

[eager spindle]

maybe not after

but every 0.02 seconds

so updates can happen very frequently or very slowly, but fixedupdates happen every 0.02 seconds

[summer stump]

FixedUpdate is called just before the physics update

[verbal dome]

Yeah just before:

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

It's in sync with the physics update loop

[ivory bobcat]

Fixed Update will be called a certain amount of times regardless of how much time has elapsed. Do note that they aren't called immediately at the specified time but simply promises that they'll be called a bunch of times if there were say.. a ten second delay between the previous and current call to Update.

[spare mountain]

which is why deltatime is irrelevant in fixedupdate 👍

[spare mountain]

isn't this just after?

[verbal dome]

I often use FixedUpdate for AI too, since I don't want it to be dependent on framerate

[spare mountain]

Fixed Update -> internal physics update

[verbal dome]

FixedUpdate happens before, which is what I'm saying

Although I very very rarely have to think if it's "after" or "before"

[ivory bobcat]

Correct, unless you're just wanting to read the value or scale some value relative to timescale.

[bleak glacier]

I'm currently trying to work out how to make an inventory system. I already have my grid of buttons so that's covered. That was the easy part though.

I'm trying to reason my way through this to figure out what I need to do to make the buttons functional though. Here's what I have so far:

Assign sprites and other info to items
Slots must be accessible in item script - probably with GetComponent right?
When item is obtained set button image to item sprite
Set value in button that indicates slot is filled
If a slot is filled make item fill the next slot instead

This isn't quite as simple as I had hoped for though and I'm concerned that my C#/Unity knowledge isn't going to cut it here. But will this general plan get me somewhere?

[eager spindle]

make an array with all the items? like a list of all the items in game?

[long jacinth]

im kind of confused i made a variable called recoil and added recoil

[eager spindle]

what I had in my inv manager is a List<Item>. Item is a ```class Item {
string name; Sprite icon; string description;
}

[verbal dome]

Maybe show your whole current script

(If you still have an issue?)

[eager spindle]

as for slots, you can have a list of slots, either instantiated at runtime(with getcomponent) or you can drag them all manually.

Otherwise pretty solid plan

[bleak glacier]

idk how I feel about dragging in 27 slots

But it would probably be easier for my smooth brain to figure out. Ik I can already do that

[eternal needle]

Your inventory system should exist completely independent of UI, but maybe describe more of what you're doing. Why do you even have buttons in the first place?

[spare mountain]

```cs pleaseee

[eager spindle]

forgor

I'm on mobile now

[spare mountain]

damn

[ivory bobcat]

Could probably use a Scriptable Object to define data for the Items where your objects (Items) in the scene would reference - if you're needing to simply store the data somewhere outside of the scene.

[bleak glacier]

I currently know nothing about scriptable objects. Where would I go about learning about them? The docs felt kind of sparse to me.

[ivory bobcat]

Just lookup some stuff on
There should be plenty of discussions or videos about them.

[verbal dome]

ScriptableObjects are generally used to make your own custom assets.
A lot of the unity settings assets are actually SO's too

[eager spindle]

you know how when you attach a script to a gameobject you can save data on that gameobject? by using SerializeField or public

imagine that but you make a object dedicated to storing data

[ivory bobcat]

They're useful if you need instances that are not deeply associated with game objects and the scene.

[eager spindle]

Besides being able to transfer data between scenes you can also make workflows for your artists and story writers that don't involve code

[bleak glacier]

So I just make an object and put a bunch of scripts on them with information?

[eager spindle]

in theory you can make a prefab with your MonoBehaviour script, and change the data of the prefab directly. works the same way as having a ScriptableObject.

[dusty shell]

Thanks for this, I figured it out

[eternal needle]

"Transfer data between scenes" is definitely not the use case for SO here.

[eager spindle]

yea I don't really do that, I see a lot of tutorials quote it though

[eternal needle]

And those tutorials are dumb

I've seen it used in many ways, even as an "event relay" basically because the people didnt know how to properly setup events. It is simply a data container, you can try to turn it into more but theres usually better options

[dusty shell]

how do i paste short code snippets without pastebin?

[swift crag]

triple backticks

[raw token]

```cs
yourCode.here()
```
Note that those are backticks, not apostraphes

[queen thicket]

how do i make a simple respawn point and check points system in my 2d sidescrolling platformer i can vc if it would help

[swift crag]

it's a fun idea that falls apart the moment you need more than one of something

or when you try to store any state in the ScriptableObject and it happens to get unloaded

[dusty shell]

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

public class TouchingDirections : MonoBehaviour
{
    // Attributes
    private CapsuleCollider2D col;
    [SerializeField] private LayerMask platformLayerMask;
    public bool isGrounded;
    public bool touchingLeftWall;
    public bool touchingRightWall;
    // Methods
    private void Awake() {
        col = GetComponent<CapsuleCollider2D>();
    }
    private bool CheckCollision(Vector2 direction, float distance){
        RaycastHit2D hit = Physics2D.Raycast(col.bounds.center, direction, distance, platformLayerMask);
        Debug.DrawRay(col.bounds.center, direction * distance, hit.collider != null ? Color.green : Color.red);
        return hit.collider != null;
    }
    private void FixedUpdate() {
        isGrounded = CheckCollision(Vector2.down, col.bounds.extents.y + 0.01f);
        touchingLeftWall = CheckCollision(Vector2.left, col.bounds.extents.x + 0.01f);
        touchingRightWall = CheckCollision(Vector2.right, col.bounds.extents.x + 0.01f);
    }
}

is this implementation the most efficient way?

[bleak glacier]

Use transform position to those checkpoint's coords. That's how I would do it at least

[queen thicket]

can you give me an example im pretty new to unity

[bleak glacier]

I am too. Just look up transform.position

[queen thicket]

and what about for detecting whern my player hits like the spikes or wtever

[bleak glacier]

OnCollisionEnter2D and put a 2D collider on the spikes

Alright. Is there a better way to get components for all of these buttons other than copying and pasting this 27 times? GameObject.Find("Button1").GetComponent<Image>().sprite = newItem1;

[wintry quarry]

Drag them in the inspector

Put them in an array

Image[]

[sage nest]

Is there a way to set the dimensions of an object rather than it's scale?

To easily set everything to have the same dimensions

[rich adder]

use a tilemap (make sure the PPU matches)

doing it this way is over convoluted

but either way you normally want the PPU to be correct that 1 box = 1 unity unit

also not a code question #💻┃unity-talk or #🖼️┃2d-tools

[stuck palm]

how can i get the date as a string?

like 2024-06-27_23-00 or whatever

[rich adder]

why not just use ToString?

[summer stump]

What type is the date to start with? Many have tostring implementations

[stuck palm]

i just want date and time so i can store files

[rich adder]

DateTime can easily read it back

[summer stump]

Is it DateTime, or a string from a filename? Or what?

[stuck palm]

both. i want to save the timestamp as a string in a json as well as use it to save files with the date and time on them

[rich adder]

you can easily just store it as a string with ToString() then remake the object with DateTime class

[stuck palm]

how can i remake it?

[summer stump]

I am asking where the date is coming FROM

Are you just writing it? Or is a DateTime object from some api?

[rich adder]

use Parse

[stuck palm]

oh no it would come from the datetime class i guess

i didnt know how to get the time

[stuck palm]

awesome, thanks

[rich adder]

string dateString = "2024-06-26 14:30";
DateTime parsedDate = DateTime.Parse(dateString);
Debug.Log(parsedDate);```

[stuck palm]

can you sort by datetime?

using linq or whatever

[rich adder]

indeed

[stuck palm]

although i guess it would be sorted kind of if you were grabbing them in file order?

[rich adder]

btw list also has a Sort method which would work

[stuck palm]

oh awesome

okay, thanks!

im trying to save multiple replays now, until now i've just been reloading and loading the same file which is annoying if i want to look at multiple replays

[rich adder]

like multiple files or 1 file

[stuck palm]

i want to make one new file for each replay. until now i'd only been able to watch the last match

easy enough to make

[rich adder]

gotcha. makes sense

[wooden socket]

hey guys, im back. this time with a smaller issue. Im getting this error: input string is not the correct format. I think its due to the way im doing this invoke.

this wont be as bad

im more rested now lol

whats weird is that its a unity only error and not VScode

im using int.Parse too

[verbal dome]

Maybe show us the code

[wooden socket]

okay

https://gdl.space/nalituzoto.cs

[verbal dome]

So you are passing a string into int.Parse that is not in the correct format, as the error says

[wooden socket]

is there a ToInt() like there is for ToString()?

[verbal dome]

int.Parse is pretty much that

What is this script doing anyway? Are you storing the score in a text...?

[wooden socket]

im sending the score to a script that sends it to a leaderboard

the name the player inputs

[jagged abyss]

tbh i think i'll start this alll

over again, with making the code

because anything i have tried so far hasn't worked, and so far my issue seems to get worse

[verbal dome]

Well, your scoreText doesn't contain a valid integer that could be converted to from string.
You shouldn't store data in a text object anyway. It should be for displaying only

[late verge]

Well, if you don't know what to do no point starting over

[verbal dome]

Consider storing it in an actual int

[late verge]

Post code, send picture

[wooden socket]

hmm, well it is an input box

[jagged abyss]

how do i post the code without sending it all as a very long list?

[verbal dome]

What is an input box?

[wooden socket]

wait okay

nvm i found it

hold up lemme rephrase

[verbal dome]

I see a TMP_InputField which is an input field

[wooden socket]

its not on the input box

@wooden socket Like I already told you here

[verbal dome]

And here

[wooden socket]

lemme change it rn

Read the Larhe code blocks section of the bot message above.

[wooden socket]

i just pass the value right?

[verbal dome]

Yes

[wooden socket]

lemme do that

[verbal dome]

I will let you do that

[wooden socket]

scoreText doesnt exist in the current context btw

[dense plume]

Speaking of context, it would be helpful to see more than this one class you have written

[jagged abyss]

it's all just crashed and gone

i love unity sometimes

[wooden socket]

https://gdl.space/vugavibepi.cs

[rich adder]

why are you using the string from the text to get number...instead of just using the score from the ScoreManager instance

[dense plume]

This is...the same class you linked earlier

[wooden socket]

true, lemme pass it

[dense plume]

This, raise an event from this mysterious ScoreManager

What exactly are you trying to accomplish?

[wooden socket]

i just want to pass it

[dense plume]

Pass what? To what? From what? Why?

[wooden socket]

i want to pass the score value to this script. its for a leaderboard

[dense plume]

How is this score created in the first place?

[wooden socket]

scoreManager gets the score from stuff in gameplay

[rich adder]

so did you do it?

[dense plume]

Alright, good. The score is tracked in ScoreManager. THAT class would be more suited to contain the code in this "LeaderScore" class. Is this a singleplayer game you are trying to create a high score system for?

If so, score manager should handle this from start to finish. When your game reaches an end condition, the score manager should send the high score to whatever container is tracking high scores, be that a file, PlayerPrefs, etc.

On the other side, if you want to then display those high scores later, a Leaderboard class can retrieve that container and read scores from it to display.

Does this make sense to you?

[wooden socket]

yea, im just stuck at how to pass the value

its public and then like

scoreManager score?

[olive fractal]

having an absolutely agonizing time where using a dont destroy on load manager im trying to create a sprite on screen and it literally does not show up on screen when i instantiate the object. do i have to instantiate it as a child of the canvas or what? it says its instantiating but then the sprite itself doesnt show up

[rich adder]

you access it the same way you have accessed it in the UI text display

[wooden socket]

looking to that now

[rich adder]

nothing changes in c# how you access values in other objects

[dense plume]

Actually, the ideal way would be to have an event fire when the score should increase, on whatever player object

[wooden socket]

i have that alreadyu

[dense plume]

And the scoremanager listens

and increments

[wooden socket]

ykw lemme send scoreManager

[dense plume]

So the score value can be private

[wooden socket]

https://gdl.space/ehecumevum.cs

[rich adder]

do you not remember anything from our earlier conversation?

[wooden socket]

this entire time, you have assumed im really stupid. I am just learning. please stop being extremely rude, discouraging, and overall unhelpful

[dense plume]

Alright presumably you are calling this function directly from somewhere else?

[wooden socket]

i LITERALLY said Im going to reference that script from earlier now

[dense plume]

Method AddPoint()

[rich adder]

its nothing to do with stupidity
more to do with attention to what others are telling you to help fix an issue, instead of ignoring it then do your own thing writing something else then complain when its broken

[dense plume]

no memes #📖┃code-of-conduct

[dense plume]

Oh yeah?

[wooden socket]

im not purposefully ignoring. I TOLD you i was overtired from working on this game for over 18 hours. You ALSO flat out told me to "pick up a new hobby" that isnt extremely disrespectful??

[rich adder]

idk what yer yappin about I helped you multiple times, i said if you refused to learn maybe do another hobby if you just want spoon fed answers

[olive fractal]

(should i... use another channel?)

[wooden socket]

also, this type of passing of values IS NOT the same from what I can tell, as its in an invoke

[rich adder]

Accesing values is done the same exact way

.

[verbal dome]

Bruh #💻┃code-beginner message

[wooden socket]

TRUE

well wait so

[olive fractal]

whatever you do do not turn the volume on this, long story essentially but i am literally just invoking a prefab and the sprite not showing up is driving me insane

[wooden socket]

it already says scoreText.text, but it SHOULD say scoreManager.score

[olive fractal]

would it be better for me to put this in general? its a weirdly trivial error

[rich adder]

yeah i usualy dont at all. just thought it was funny since we helped this person for 3 hours earlier

[verbal dome]

I don't mind, it's just hypocritical

@wooden socket Did you do any C# beginner courses yet?

[rich adder]

true true. just letting them know, i didnt say delete it or anything

[dense plume]

Are you...a beginner?

[wooden socket]

well now the object reference is required for the non static field

[rich adder]

because you're not accessing it from the instance?

[olive fractal]

i mean, no, but the error itself is kinda a novice error, hence here

[verbal dome]

You need to reference the instance

[wooden socket]

well im going to college for game design soon. im trying to get a head start by doing projects and taking classes

[olive fractal]

like, ive never had anything like this happen before so my immediate thought was. i am missing something trivial and im stupid

[rich adder]

You did this is with the display text thats what Im saying , its nothing new here. The process is the same

[wooden socket]

okay so at the top I say public scoreManager right?

or public class scoreManager

[verbal dome]

You should really start with the basics. Like learning referencing, static classes, and much more
Well not static classes in this case but singletons

[rich adder]

no because score manager is a singleton it doesnt need references

there is a static instance

[dense plume]

the dreaded global state

[olive fractal]

i would strongly recommend following along with a tutorial like roll a ball @wooden socket

before jumping into a project solo with no experience

[rich adder]

it has been suggested multiple times

[olive fractal]

fantastic

you can literally always come back to this when you have some knowledge of fundamentals

[wooden socket]

please just tell me this ONE small part of how to do this

this is the last error i have

[dense plume]

The SpriteRenderer reference you have is currently empty in the inspector, is this intentional? Sorry I am having some trouble gathering what is happening in this video, Discord is kind of glitching it out for me

[wooden socket]

@rich adder what the hell is wrong with you fr

im just trying to learn and you are being a jerk

[rich adder]

you been told how to do it multiple times..

[rich adder]

but you're not thats the thing

[wooden socket]

I AM

[rich adder]

remember earlier you said "i got this working now i go learn c#"

[wooden socket]

i want to learn how to do this so fucking badly man

[polar acorn]

If you were trying to learn you'd have actually made an effort to solve anything on your own instead of guessing randomly until we get frustrated enough to just write it for you

[rich adder]

yet here we are

[wooden socket]

i told you man, ive been up for so long and im tired. theres no need to say "here we go again" and act like im some kind of fucking clown

its just discouraging and rude

[olive fractal]

apologies, which spriterenderer are you talking about? Like attached to one object

[polar acorn]

then stop trying and come back when you're capable of learning anything at all

[wooden socket]

fuck you man

thats really rude

[polar acorn]

This is a gigantic waste of everyone's time

[dense plume]

IL_ARIA object -> Mon Data component -> Sprite field

[polar acorn]

If you are, by your own admission, unable to learn anything

why should we waste time trying to teach

[wooden socket]

im not unable to learn

i am saying

[olive fractal]

ah. Give me a second

[wooden socket]

i dont know how to do this one specific thing

[rich adder]

this one thing relates to what was explained to you earlier..

[polar acorn]

Or the previous one specific thing. Or the one specific thing before that. Or likely the next ten one specific things

[wooden socket]

i looked at the display text thing

and from what I can understand

and what you said I need to use a .

[rich adder]

do know what the . does ?

[wooden socket]

but im asking what I put on the left and right ends of it

[wooden socket]

its the 's of code

[rich adder]

I'm geniunly asking and not even trying to be an ass.

[olive fractal]

oh girl you can not be asking character by character help

[rich adder]

ok so then why were you confused about how to access the int

[wooden socket]

because it didnt wpork

look

[wooden socket]

so helpful and kind

[rich adder]

score is already an int, why are you trying to parse to int

[wooden socket]

well, I want to make it a string

[rich adder]

also you're not using the static instance

[wooden socket]

and when I do this

[rich adder]

inside the earlier script you dont know how to make it string?

[dense plume]

(Not using a static instance is technically correct)

[summer stump]

Not with that syntax it's not

[dense plume]

lel

[rich adder]

look how access score in the UI script

to display score as text

[wooden socket]

but its different

because look

[rich adder]

no its not

[dense plume]

🍿

[wooden socket]

dude what the fuck

[polar acorn]

We literally went over how to access the score from your singleton instance last time. You wrote it right then

just do that again

[dense plume]

Hey I am all down to help you, but we gotta focus here and stop arguing

[polar acorn]

you already know this

You did it already

[summer stump]

Stop swearing at people

[wooden socket]

then dont post a fucking popcorn emoji

[frosty hound]

If you're not actively participating in anything productive, please don't comment.

[wooden socket]

i have been asking for help and multiple times its been you guys just being rude

its very discouraging and unhelpful

[dense plume]

Fair enough but I was previously helping this person and I am helping @olive fractal

[summer stump]

You have, many times, been told exactly what to do

[frosty hound]

Make a thread then, and anyone who wants to sit through teaching the basics, can. Everyone else can choose to stay out of it.

[summer stump]

You need to stop and learn the basics

[wooden socket]

im trying to

[summer stump]

I always recommend these
https://www.w3schools.com/cs/index.php

And then
https://learn.unity.com/pathways

[rich adder]

"I just need this one thing"

[wooden socket]

and at the same time, you being rude REALLY isnt helpful

[rich adder]

yet we spoon fed you for 3 hours until it worked

[frosty hound]

#💻┃code-beginner message

[summer stump]

I have not seen anyone being rude except you

[wooden socket]

i know you think im stupid and as @rich adder said "pick up another hobby"

[polar acorn]

I didn't start rude. I became rude after three hours of teaching you how to access a variable

[verbal dome]

@wooden socket what about this #💻┃code-beginner message

[wooden socket]

my only confusion is the parenthesis

[rich adder]

biting the hand that feeds..

[dense plume]

I also recommend this resource from microsoft on C#: https://dotnet.microsoft.com/en-us/learntocode

[wooden socket]

dude cmon

the error now is different

its about object referenes are required for the non static field

[summer stump]

You really, truly need to just take a basics course.
Have you done the w3schools or microsoft courses that have been linked? What about the !learn course?

[eternal falcon]

:teacher: Unity Learn ↗

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

[rich adder]

the error wont change if you don't do it properly 🤷‍♂️

[summer stump]

This is not rude. It is all that will help

[wooden socket]

and at the top, I tried putting public scoreManager score and it didnt work

[summer stump]

Well yeah, that won't work without assigning a reference

[rich adder]

whats so complicated about copying what you did earlier

[summer stump]

Also, score is a very misleading name for ScoreManager. Keep in mind that it is not the score itself. Just be careful

[dense plume]

You are trying to declare a class reference without initializing it if that's what you've written

Did you assign this field in the inspector?

[rich adder]

score isn't a static field so it needs to be accessed through an instance.

[wooden socket]

doing that now

[rich adder]

the static instance exist

[wooden socket]

well it is

it is static

[rich adder]

look the dam UI score..the syntax is there.

[wooden socket]

I DID

[stuck palm]

why isnt this screenshot working?

[polar acorn]

So, how do you acces score from there

[rich adder]

is that the path ?

[stuck palm]

if (frameIndex == 1200)
        {
            string fileName = Application.dataPath + "/ReplayScreenshots/Replay" + DateTime.Now + ".png";
            ScreenCapture.CaptureScreenshot(fileName);
            _replay.screenshotFileLocation = fileName;
            GameManager.Instance.SendNotification(MessageType.Info, "Screenshot taken");
        }

this is how i've done it

[rich adder]

you can't use : in a path

I don't think

[dense plume]

invalid characters in path

[stuck palm]

ah

[wooden socket]

i dont know man

[polar acorn]

So, read the code you already did and check

it's right in front of you

you can just, like, read it

[wooden socket]

may have figured it out

[stuck palm]

changed it and it still doesnt work. is it because i havent created /replayscreenshots/ yet/

[rich adder]

thats right you need to create folders before you try to save a file there

[dense plume]

worth creating the directory first to see

[stuck palm]

i see. its just cus the unity recorder creates the folder automatically so i thought this would, too

[rich adder]

nah this is a .net/c# thing

unity has no control

[alpine valve]

I have a question about generating a graph for A* pathfinding in a 2D platformer.

My game world will not be represented purely by tiles. So Instead of having a "grid" of nodes and connections where a node is placed above each walkable tile in my scene, could I just generate nodes at the "start" and end of platforms? Like over their corners/vertices or something?

[dense plume]

It seems by the sound of it...that the structure of your project is perhaps a little off. You should have a player object that does things. If it does a thing that earns a point, it should raise an event. This event should be listened to by the Score Manager class, where it will increment an integer. This integer can then be stored somewhere as a high score (file, playerprefs)

[wooden socket]

ykw im gonna be back later

[rich adder]

why not ust use the 2D Navmesh tool

[dense plume]

Can you describe the current structure, the current logic flow of your game

[wooden socket]

what some of you did was very rude. i didnt like that at all and was very discouraged. sorry for not understanding, but there is no need to be rude

[rich adder]

everything everyone says is rude, are you 12?

[dense plume]

A professor in college would perhaps roast you even worse for this, tbh

[wooden socket]

THIS ISNT RUDE???

[wooden socket]

and this isnt either??

ykw goodbye. im astonished at how unwelcoming this waas

[dense plume]

Can you answer the question I asked that will assist your issue?

[polar acorn]

It took four hours to explain how to use ToString they are not prepared for events

[wooden socket]

i fixed it already

however

[polar acorn]

Oh no it was very welcoming. The amount of time it took to explain basically anything far outstripped the "welcome" period

[wooden socket]

you didnt have to be dicks about it

[rich adder]

you're the rude one tbh you're projecting

[frosty hound]

@wooden socket You finally fixed it, move on.

[stuck palm]

when i do the ScreenCapture.TakeScreenshot thing, the game freezes for a split second. is it possible to avoid this by putting it in a coroutine or async or something

[frosty hound]

And now go do your promise of learning C# basics before your next question.

[wooden socket]

i just dont appreciate the reacts and making fun. it hurts a lot

[frosty hound]

If you find yourself asking one, make a thread so we can avoid all this.

[dense plume]

File system access will do this. It is possible to use an async method

[frosty hound]

I told you twice to make a thread, so you can deal with people only interested in holding your hand. You chose not to.

[alpine valve]

If you are referring to the built in navmesh tool that comes with Unity I believe it's only compatible with 3D? Unless you meant another tool

[rich adder]

probably better off using the capture directly from the Graphics card like how RT does it

[dense plume]

True

[rich adder]

nah this one
https://github.com/h8man/NavMeshPlus

[stuck palm]

how can i do that? and what's RT?

[dense plume]

@olive fractal did you fix your sprite issue?

[rich adder]

Render Texture. just grab the texture basically and save that

[olive fractal]

Okay, updated, shorter video, and I'll try to explain the bug this time.

Once again, please turn off audio before watching this, I'm working with some buggy audio files that are kind of painful to hear.

So, I'm just trying to instantiate a Sprite on the screen, using one of my managers (it's dontdestroyonload). The object is initializing properly but for whatever reason, it doesn't seem to have a sprite inside of it?

[olive fractal]

No, but I have a way more concise video, where the thing mentioned earlier is fixed.

[stuck palm]

so i just take a sprite from the rendertexture or something and save that to the disk? as sniflheim said apparently its filesystem which makes it lag and not the screencapture?

[dense plume]

Ehh it can also be Unity being slow about it, I like navarone's solution.

[olive fractal]

Can you do things like makedir from inside Unity? I've definitely never tried, lol

[rich adder]

I use it with async too and have no hiccups 🤷‍♂️

[stuck palm]

i havent actually touched async before

only coroutines

no idea how it works

[rich adder]

if you used coroutine the concept is the same

except this is true async

[olive fractal]

https://gist.github.com/unitycoder/9fbd682f7d250c016d6cc0d306290966

Possibly helpful?

[rich adder]

you should have no hiccups anyway you should be able to save file during play np

[stuck palm]

might just be in the editor, then.

[stuck palm]

looks like it fits my bill exactly lol, thanks for showing me this!

[rich adder]

yeah idk System.IO can be slow in general but it should not hiccup unity afaik.

[dense plume]

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

[rich adder]

you ideally want to avoid void as async method return type

oh comment went poof

[dense plume]

Yes I realized the brain fart there

[rich adder]

although this can't be avoided sometimes esp when dealing with UI

You can't use some event that uses Actions without using void 😛

[olive fractal]

😭

[dense plume]

This object is a canvas renderer with no canvas parent

[olive fractal]

do you have to instantiate it as a child of the canvas?

[dense plume]

Yes

[olive fractal]

https://docs.unity3d.com/ScriptReference/Transform.SetParent.html

Okay, where I kept getting tripped up was, just feeding it a transform works? Feels weird syntactically

[dense plume]

Yeah or set the parent when you instantiate

Thats an overload

[olive fractal]

if it's not too much to ask, what's the syntax?

[rich adder]

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

[olive fractal]

Ah, thanks!

[dense plume]

Object comma parent transform i think

[stuck palm]

turned out pretty well 😄 i tend to write a lot of code before testing anything, for better or for worse, which makes it more satisfying when it all works first try

[olive fractal]

(I'll get back to you guys in like five...)

[olive fractal]

oh this is really sexy UI, nice

[rich adder]

lookin good!

[olive fractal]

Are you writing a fighter?

[stuck palm]

thanks!

[stuck palm]

im making a platform fighter rn, yeah

the past week has been making my replay system actually work to begin with

[stuck palm]

thanks!

[olive fractal]

Now you just gotta check if the videos turn out right when you watch 'em

[stuck palm]

yeah, i'm recording all the inputs when the game is playing and replaying them, basically resimulating the whole game. if one frame goes whack the entire thing blows up

[olive fractal]

Type mismatch with the Canvas, y'all... this is also a prefab I'm using, should I just findtype canvas and get its transform from there

[olive fractal]

you're accounting for rng, right

[stuck palm]

i've been spending a lot of time making my game very deterministic so the inputs work the same no matter what you use

[dense plume]

Does the class that instantiates the prefab know about the canvas?

[stuck palm]

yes i've accounted for that, each replay saves the seed of randomness so any RNG plays out exactly the same

[olive fractal]

It sure doesn't, it's scene independent and when I tried to give it the Canvas's transform it gave me the type mistmatch

[stuck palm]

thanks to @swift crag's suggestions im getting very close 😄

[dense plume]

Lets see some code

[olive fractal]

Right, this is a prefab...

public class EncounterManager : MonoBehaviour
{
    [SerializeField] List<GameObject> monData;
    public static EncounterManager instance = null;                //Static instance of GameManager which allows it to be accessed by any other script.
    public MonData enemy = null;
    [SerializeField] Transform canvas;

    void Awake()
    {
        //Check if instance already exists
        if (instance == null)

            //if not, set instance to this
            instance = this;

        //If instance already exists and it's not this:
        else if (instance != this)

            //Then destroy this. This enforces our singleton pattern, meaning there can only ever be one instance of a GameManager.
            Destroy(gameObject);    
        
        //Sets this to not be destroyed when reloading scene
        DontDestroyOnLoad(gameObject);
    }

    public void ChooseEncounter(){
        enemy = null;
        GameObject m = monData[Random.Range(0, monData.Count)];
        MonData data = m.GetComponent<MonData>();
        if (data != null && m != null)
        {
            enemy = data;
            StartCoroutine(StartBattle(m,0.1f));
        }
        else
        {
            Debug.LogError("The selected game object does not have the specified script attached.");
        }

    }

    private IEnumerator StartBattle(GameObject m, float delay){
        yield return new WaitForSeconds(delay);
        secondBattleStart(m);
    }

    public void secondBattleStart(GameObject m){
        SoundManager.instance.efxSource.clip = enemy.cry;
        SoundManager.instance.efxSource.Play ();
        Instantiate(m, canvas);
    }
    
}

[dense plume]

And what exactly does the error say? You've got a console message?

[olive fractal]

No error, just that the image doesn't appear (see video)

[dense plume]

You said it gave a type mismatch?

[olive fractal]

I at least know it IS instantiating, but there's clearly an image visible in the prefab and then it's not visible after 😐

[alpine valve]

I could be misunderstanding something important here, but I think the problem with this solution is in a platformer game context it would create a mesh where the whole scene (-any obstacles) is a big walkable mesh. So it would only work for flying enemies? That's why I came up with my original proposal of nodes on the "start" and "end" of platforms like this. (greatest diagram ever lmao)

[olive fractal]

Oh, right, if you attempt to attach the Canvas as the Transform, it literally just says type mismatch

[dense plume]

Oh, don't do that

attach the gameobject that the canvas is on

it will pull the transform

What you're assigning is a transform

[rich adder]

oh you're making platformer ? mb thought it was topdown..Gotcha yeah using node makes sense now

[dense plume]

not the canvas component itself

[olive fractal]

No, I attempted that

It won't even pull the transform on this 😐

[dense plume]

ooooh

You can't assign a scene object to a prefab field

These things exist in different contexts

You'll need some way to find this canvas transform when you spawn the encounter manager

[olive fractal]

oh god, what's the workaround, then? Should I like

find_object_of_type<Canvas>()
parent = canvas

because theres only one canvas in scene ever

[dense plume]

Yes, it's kind of...bad, but yeah

[olive fractal]

its certainly special. lets see if it cooks, haha

[dense plume]

Why can't you have the encounter manager already in the scene?

[alpine valve]

Its all good thank you for the suggestions!

[olive fractal]

im really early in dev, so honestly, yeah, its not like im going to have to use it outside of here. ill just spawn one every time i change to the battle scene

wait i literally dont even have to, nvm

[dense plume]

oh, don't do that, make it dontdestroyonload and make sure you use a "zero" scene

Singletons being created an destroyed for each scene will make hell for you later

or, just use the same battle scene for every battle and spawn what you need, but have the encounter manager already in there

[queen adder]

yo I needa cook something up on unity (in the next 22h) for a college assignment, Ive never used unity before and I got no idea what tf im doin I just downloaded unity. Please someone tell me where to start 😭 🙏

[dense plume]

Oh dear

[rich adder]

check pin in this channel

[olive fractal]

yeah, i think thats what ill be going with X|

[queen adder]

Im cooked bruh, If I dont get it in I dont get on to my next year

[dense plume]

It's great fun really

[queen adder]

I needa make like a top down 2d racing game kinda thing I guess 🤔

[dense plume]

I use a scene like that and literally spawn everything at runtime

[olive fractal]

do rollaball it will take less than 24 hours

[olive fractal]

fortunately its not that resource intensive because its literally a pokemon-like

[rich adder]

make a Box that has rigidbody2d and disable gravity

now you got a car

[olive fractal]

lol

[dense plume]

Nice I do like what I see in the video there very classic looking

[olive fractal]

haha, dont give me that much credit yet, its mainly derived from the unity roguelike tutorial

[dense plume]

Yeah definitely have a battle scene with all the "scaffolding" already in place

[olive fractal]

its got some nice 2d movement. very smooth

[dense plume]

then fill in the blanks with context for the battle

Anything that will be there every time should be in the scene

[placid flax]

hey, I'm trying to make a shooter game but I can't firgue out how to make the ammo count on my HUD work, does anyone got some methods I can use?

[dense plume]

Well, what have you tried?

[placid flax]

I tried a bunch of different functions for getting the ammo count from my gun script to mu hud script but none of them have worked and I can't find any videos on it for the life of me that work

[olive fractal]

also that worked 🥲

thanks snif

[dense plume]

Easiest way is to reference this "gun script" in the hud script

[olive fractal]

yeah, this should be easy as having an accessible variable, can we see the HUD script?

[dense plume]

You bet lemme know if you need more help with that, kinda my specialty, building scenes up at runtime

[queen adder]

Hey say I wanted to make something like this - https://youtu.be/vF9R7dhHJCw?si=HnbWRz3wHFSgFbpt

^ which one of these would I use 😭

[placid flax]

how do I do that?

[queen adder]

^ his different to mine in the video

so idk

[dense plume]

Hud script should have something like public GunScript gunScript; near the top, inside the class braces, then assign this in the inspector. Make sense?

[queen adder]

idk if I pick "universal 2d" or "2d (built in render pipeline)"

[placid flax]

so I can just make a var?

[olive fractal]

and then in the code, hudText.text = gunScript.bulletVariable

[dense plume]

Pretty much, yep

[placid flax]

jeeze, ight thanks man 🙂

[dense plume]

built in is fine

You should be able to follow the tutorial regardless. Those are render pipelines and dictate how the game is rendered under the hood. Not something you should be concerned with as a beginner

[rich adder]

this isnt a coding question btw

#💻┃unity-talk

[queen adder]

my bad chronum

[rich adder]

also URP is prob overkill in 2D unless you need lights

[astral basin]

i have an android project and when the resolution is 18:9 everything works well but when i set it to my phone resolution only one image gets weird, what is causing this and how can i fix it?

[dense plume]

Sorta looks like you've linked the same image twice

Both say 18:9

[astral basin]

oh my bad one sec

thanks

[dense plume]

Alright I'm not crazy, lol

Make sure you've got anchors and pivots set right on that image component (assuming this is all UI canvas stuff?)

[astral basin]

yeah its ui stuff

how do i find these anchors and pivots things

that you are talking about

[dense plume]

RectTransform component on the object

Top one, can't miss it

[astral basin]

it should beon 0.5?

[dense plume]

Alright it doesn't say it's set to stretch or anything right?

[astral basin]

someof my components are different

[astral basin]

nope

[dark sluice]

so i have a camera following a falling ragdoll (the player) but the camera is shaking crazy because its following a falling ragdoll, anyway to get it to shake less? (ive tried using a empty follow object that follows the ragdoll and the cam follows that but same output 😦 )

[dense plume]

screenshot the whole recttransform component

[dense plume]

Use interpolation

[dense plume]

Aha! See that blue cross arrow bit?

[astral basin]

yes

what about it

[dense plume]

Says stretch on box axes
