How?

[hot laurel]

sounds like the zombie chase is in wrong axis

[void dawn]

how do i fix that ?

[visual linden]

Start by sharing the code in question :)

    if (Input.GetAxis("Mouse ScrollWheel") < 0f ) // forward
        {
            Camera.main.orthographicSize++;
        }
        else if (Input.GetAxis("Mouse ScrollWheel") > 0f ) // backwards 
        {
            Camera.main.orthographicSize--;
        }

Currently I have this as my code, but it seems to be really.. temperamental? I'm trying to "zoom out" of my 2d game, but I have to scroll down on my mouse anywhere between 5 - 50 times just for it to scroll out

I'm not sure why, either, could anyone please give me some advice

[wintry quarry]

I would start by switching to GetAxisRaw

[void dawn]

https://paste.mod.gg/mxkvcoejlvtq/0

here is the code for the zombie

[bitter apex]

thank you, It turns out all I had to do was change it from being in FixedUpdate() to Update(), i guess fixedupdate works differently to how i expected it to 🗿

[wintry quarry]

Oh you didn't mention that. yeah input needs to be handled in Update, not FixedUpdate

[grand snow]

ortho size is a float so you can do:
camera.orthographicSize + (Input.GetAxis("Mouse ScrollWheel") * multiplier);

[bitter apex]

oh lovely. thank you

[bitter apex]

Yeah thanks, I'll keep that in mind for the future.

[grand snow]

@bitter apex and to make it go backwards do (1f - Input.GetAxis("Mouse ScrollWheel")) * multiplier

no wait it should be axis * -1 mb i forgot its from -1 to 1

[wintry quarry]

that's not right - you'd just multiply by -1

[grand snow]

haha yea i just realised

@bitter apex i was wrong, correction above ^

[polar acorn]

Did you take the NavMesh surface off of the zombie like we said yesterday

[void dawn]

yes

[polar acorn]

And your zombie no longer had a rigid body?

[void dawn]

yes he no longer has that

[polar acorn]

And is the animator on a child object, rather than the one the NavMesh Agent is on?

[void dawn]

now it is

[polar acorn]

Okay and did that solve the problem

[void dawn]

let me try

a warning and an error

Failed to create agent because there is no valid NavMesh this is the warning

this is the error
MissingComponentException: There is no 'Animator' attached to the "ZOMBIE" game object, but a script is trying to access it.
You probably need to add a Animator to the game object "ZOMBIE". Or your script needs to check if the component is attached before using it.
UnityEngine.Animator.SetBool (System.String name, System.Boolean value) (at <9b89611000504a9585efec19be4faf3b>:0)
ZombieAI.Update () (at Assets/scripts/Zombie AI.cs:60)

well i did create an empty child to put the animator in

[polar acorn]

First error: We already covered this. You need a NavMesh Surface for a NavMesh Agent to be on.

Second error: You need to drag in the animator that you moved to a different object and remove the get component calls to it

[void dawn]

you know what , i think before i go on with this project i should do a unity basics course and a c# basics too

https://codeshare.io/g8koNY

why is it that even though I set previousItemX as inactive, it still is active when I play? I wanna be able to only have one object from each category active

[polar acorn]

First off, if you ever find yourself numbering variables, you should be using an array instead.

Second, show the inspector for GameManager

[rich adder]

lord..

[inland kettle]

☠️

[polar acorn]

So, those first 9 things - are those prefabs or objects in the scene

when you click on them, what highlights

[inland kettle]

Prefabs

[polar acorn]

Then that's your problem

You're disabling a prefab

[inland kettle]

No I’m disabling the Actual (item) s

Those prefabs are destroyed in update

Those work

[polar acorn]

So are the objects in the inspector prefabs or objects in the scene

[inland kettle]

Top 1 to hair 3 are prefabs, actual top 1- actual hair 3 are game objects

[polar acorn]

Ah, wait, I see, you've got separate variables for the prefabs and the instances.

[inland kettle]

Yes

[polar acorn]

This is part of the reason you should be using collections, easier to read

[inland kettle]

Will take note for future projects, still quite new to this

[polar acorn]

They're re-activated by the wearClothes method, which is being called from somewhere else, for now, just put return; as the first line of it so the rest of the function is skipped. Do they all start up deactivated then?

[inland kettle]

I thought you can’t put return in void functions?

[rich adder]

ofc you can

[inland kettle]

Whaaaat

[rich adder]

it just returns early without any value

[inland kettle]

Ohh

[inland kettle]

Do I do the same to wear clothes 2 and 3?

[polar acorn]

Oh, right

Do that

(Definitely learn arrays)

[inland kettle]

I’ve learnt arrays, just didn’t think of using them lols

[scarlet skiff]

i dont get it are these not the exact same return type? whats the issue

[rich adder]

yeah once you're adding numeration to your variables, its def time for an array

[inland kettle]

It says unreachable code detected

[polar acorn]

Yes ignore that

[rich adder]

the tuple?

[polar acorn]

Make a class or struct for this, don't use a tuple as a list parameter

[inland kettle]

Oh but won’t nothing happen then

[polar acorn]

Yes, that's the point

We want to disable these functions and see if Start is actually deactivating things

[swift crag]

why are you using State in the definition of the interface?

[polar acorn]

so we're removing the code that reactivates them

[inland kettle]

Ohhh

[swift crag]

Is that a completely different State?

[scarlet skiff]

state is a class that inherits fro mthe interface istate

[inland kettle]

When I click the objects nothing is activated

[polar acorn]

Well, yes, that's what is to be expected with the functions disabled. But everything's now properly starting disabled, right?

[inland kettle]

Yes

[swift crag]

so any IState must expand into a list of State?

rather than into a list of IState?

[polar acorn]

So, it seems one of those WearClothes functions is being called on startup, which is why there are some that are active on start

[humble hound]

is this a me thing only orr

[rich adder]

click Explor out LEarning pahways

[swift crag]

what's the URL you're at right now?

[polar acorn]

Seems like it

[humble hound]

this is the junior pathway

cant start it

getting 404

[swift crag]

paste the exact URL you're trying to access

[rich adder]

clear your browser cache

[scarlet skiff]

ye it would be helpful if i can do it this way

[humble hound]

its working now rebooted router

[rich adder]

a nice flush of DNS works too

unity has changed some links around and caused massive headaches

[inland kettle]

None of them are active on start, the functions are only called when I click on something during playtime, just that when I click multiple items it doesn’t destroy the item I clicked before

[swift crag]

This compiles just fine.

Make sure that you have the correct State

[polar acorn]

Okay, your initial problem said they were active when you hit play, so that was the problem I was trying to solve

[inland kettle]

Ohh sorry I should’ve worded it better

[swift crag]

I don't see one in UnityEngine.UIElements or System.Collections.Generic, but maybe you have another State defined in the root namespace

[polar acorn]

Which is why I suggested using a struct instead of a tuple, the compiler wouldn't let you create one with the wrong type of State and it'd be easier to see the root of the problem.

[rich adder]

tuple is just a lazymans struct anyway

[polar acorn]

So, what, specifically, is the problem? It's not disabling the old ones when you're trying to change?

[inland kettle]

So when I click an item it activates it in the scene, and it stores the previous activated item in previousItemX, which I then deactivate. Problem is that’s not working

[polar acorn]

Try logging the item before you deactivate it and see if it's the one you expect

[inland kettle]

Sorry, what’s logging?

[rich adder]

printing a log.
Like Debug.Log

[inland kettle]

Oh debug

[rich adder]

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Debug.Log.html

[inland kettle]

Okay

[heady pagoda]

im working on this game where theres this like little companion that follows me around and it pretty much works but when i actually start the game the character follows me but also flys in my direction. When i add a rigidbody it somewhat fixes it but the character just starts glitching out and "thrusts" into me. how do i fix this?

[rich adder]

how can we know if you don't show the code

also send !code as link

[rich adder]

as links mate

anyway moveTowards is probably not a good way to implement this. either way, seems your Y axis aren't level

if player origin is at 0, 5, 0 and the companion is at 0, 2, 0 it will float to 0,5,0

you probably want to use a Navmesh agent though,

if you ever encounter a wall between you and your companion it will just phase through the wall

[slow knot]

uh how many lines on average should an AI be

[rich adder]

there is no number

whatever amount required

[slow knot]

alright was just asking where the line goes between rididucilously long script and normal script

im making an AI for my game (my first game that is)

its currently like 200 lines

202 actually

but aight thanks

[rich adder]

the line count only matters for your readability it makes 0 difference in the end code

[heady pagoda]

also should i change it into FixedUpdate? because i set it as 0.02F but sometimes its faster and other times its slower without me changing anything

[slow knot]

to make my code more readable, do i place all variables of one sort, for example public ranges and the privates next to each other

Becasue right now my code is a complete mess with functions everywhere

[rich adder]

thats because you're missing time.deltaTime, look at the docs for moveTowards .

tbh this whole thing is a mess, just use a navmesh agent

you will have a better companion follower that can actually avoid obstacles

[rich adder]

organize it however is most legible to you
I typically do

public class Example {
  public field
  private field;

I rarely have public field just an example, put my public at top like events

[heady pagoda]

i tried something like that with another model and it didnt work but that was prob cause the model wasnt rigged or something

i can give it another try

[rich adder]

model and rigging has 0 to do with how a navmesh agent functions

those are just visuals

you can literally slap anything on navmesh agent and it will move it

navmesh agent is just controlling the transform moving it on flat mesh baked areas

[heady pagoda]

i only have this vid from the nav mesh version and the companion just went flying

i gave up on it and did the thing i have currently but i can try again

[heady pagoda]

i didnt show the script or nothin though

[rich adder]

already see something wrong

why does navmesh agent have surface on it?

navmesh surfaces are powerful but you dont put them on moving agents..

[heady pagoda]

the tutorial i watched was super old and it had a nav mesh agent and those things used to have the bake thing but then they removed it from the agent no?

so i just added the surface to bake it

[rich adder]

things have changed yes

you add navmesh component then you bake it yes, you keep it on a static ground usually unelss you know what you're doing with moving objects.

[rich adder]

I suggest you go through this
https://youtu.be/SMWxCpLvrcc

[heady pagoda]

thx

[rich adder]

this is from unity so you know its good

[wanton epoch]

Does anybody by any chance know of a tutorial to add a character with animations to a first person game with the ability to see your hands and feet? I am currently using just a capsule with my own player movement script. But I cant seem to figure out how to switch the capsule to a character model while also allowing it to move with my player script.

[rich adder]

your movement code what does that have to do with visuals

one shouldn't impede the other

so idk what this means

how to switch the capsule to a character model while also allowing it to move with my player script.

unless you have animator set to drive root move transforms the animations are just visuals they don't touch movement

apply some mixamo animations or something to a child object that has the humanoid rig
just make sure your animator states match your script actions.. if your script is moving your controller with speed then start moving animation etc.

[frigid sequoia]

If I want to pass a enum parameter to a method from another class, where do I have to declare the enum?

[rich adder]

wdym declare it in any file

[frigid sequoia]

In the class calling the method, in the class that has the method or in both?

[ripe shard]

Anywhere accessible from both places

[rich adder]

if you nest the enum definition in the class then you need to preceede it with that class if you access it from else where

[echo ruin]

If you have an enum you should be able to just put it in the parameter

[rich adder]

Class1.Enum.
instead of Just

Enum

[frigid sequoia]

Mmmm, I see

I basically want to make like a script that is basically a status effect that other classes can generate upon different targets, and I wanted to have like a enum to identify the stacking method

So I guess I should have the enum in the class that generates the status, and reference that on the status itself

[rich adder]

i always put enums in their own files

[timber tide]

So, if you make the enum inside of the class then you need to append the class type onto that enum

[echo ruin]

You can just make an empty script and just have the enum there. Then any class can call it

[timber tide]

if you have a namespace, you can toss it onto that and use it everywhere in that scope without having to append the class type onto it

well, you can also do without a namespace inside of a 'global' scope, but I suggest always including a namespace anyway

[rich adder]

basically if its defined in another class you are doing

public class Foo{
    public enum MyEnum { x, y, z }
    public void MethodWithEnum(MyEnum val){
    }
}
public class Bar{
    private Foo foo = new();
    void Method(){
        foo.MethodWithEnum(Foo.MyEnum.x);
    }
}```

[timber tide]

Should only be using nested enums within the class itself anyway. If it's being used elsewhere then stick it on a more outer scope

[frigid sequoia]

So I should be doing this???

Or should I have a more general access?

[rich adder]

wdym "enum ref"

[timber tide]

What's the enum called and what does it correspond to

[frigid sequoia]

They need to know what the enum means

The enum is called in the initialization of a status effect, to check what it should do in relation to other status effects

In like, if they are the same, do they just happen togheter? Does the more recent one overrides the other? Does it reset the duration of all status of the same name?

[timber tide]

namespace ProjectName
{
  //UtilityScript.cs
  public enum StatusEffect
  {
    Blind,
    Freeze,
  }
}

namespace ProjectName
{
  public class Skills
  {
    public StatusEffect StatusEffect;
  }
}```
Simplified idea

[fleet venture]

why can i not get a gameobject from a scrollview?

[timber tide]

Ideally you do split the namespaces up a bit more, but that can be a little confusing unless you've the idea how to group everything.

Like I would have a Entity namespace, Stats namespace, ect

[rich adder]

why not

[frigid sequoia]

So I make those enum in like separated scrip on the namespace of the whole project?

[fleet venture]

its not a thing

idk why

[rich adder]

scrollview is just a component, the gameobjects are on the child

[rocky canyon]

u got a class named Props?

[fleet venture]

oh

[fleet venture]

uh no

[timber tide]

Not a requirement, but usually not the greatest practice to let stuff hanging out in global space. Buttt if you're the only one working on the project it matters less.

[fleet venture]

its the field

so how do i do it then

do i make it a GameObject type?

[frigid sequoia]

I mean, that seems like something I would want to have access from anywhere on the project

[timber tide]

Yeah, until you install a plugin and they have the same class names as you. WHICH they will have their own namespace unless they want to piss people off

[rich adder]

just just make a field for it

[fleet venture]

ok

[rich adder]

put your item in the slot and you're done

[fleet venture]

ye

ok

[frigid sequoia]

Am I even using classes there?

[timber tide]

your classes become wrapped in the namespace

[fleet venture]

ok diff question why can i not see my game

nvm

im stupid

i was zoomed in

[frigid sequoia]

But this would not include any class right? I would just state at the begining like using ProjectName and I would have access to the enum, isn't it?

[timber tide]

Without the namespace, if you made a Enum then you can access it anywhere without any extra syntax*. I'm just saying that it's good practice to use namespace because imagine if you wanted to make a class called Image, but then you run into a problem that Unity also has a class called Image... how do you identify which one is yours?

[frigid sequoia]

Doens't it warn you when you do that?

[timber tide]

It does, but if Unity didn't wrap it in Unity.UI namespace then you couldn't make a class called Image yourself in that global space.

[fleet venture]

oh eew

[rich adder]

welcome to .net 4

[fleet venture]

unity uses an old c# version?

oh god thats 4 versions older than what im used to

[wintry quarry]

https://docs.unity3d.com/6000.0/Documentation/Manual/csharp-compiler.html

[rich adder]

when core CLR drops we will have modern .net & c#🤞

[fleet venture]

nice when will that be

[rich adder]

hopefully unity 7

[wintry quarry]

unknown

probably in 1.5-2years

[fleet venture]

how often does a unity version drop

ah ok

[frigid sequoia]

So.... something like this would be fine to use?

[timber tide]

Well, the namespace would include all classes that want access to those enums

Like as an example above if I had a Skill namespace then I'd include all scripts that deal with my abilities and need to share those enums among each other

[frigid sequoia]

So... in any class that I use the using ProjectGeneralEnums, it would become wrapped by the namespace then?

[timber tide]

Any class that wants to use those enums you'd wrap into the namespace, otherwise you have to #Include 'Using' it on that file or explicitly state where those enums comes from

[wintry quarry]

I think of namespaces this way:

A namespace is just part of the type name. Your full type name is ProjectGeneralEnum.StackingMode But if you put using ProjectGeneralEnum you can just write the short version StackingMode

So when you want to use that enum you either write the full name ProjectGeneralEnum.StackingMode or you do using ProjectGeneralEnum so you can just write the short version StackingMode

[timber tide]

And if it's all in the same namespace then you don't even need to use 'using'

[frigid sequoia]

Oh, ok

I am not very used to namespaces tbh

[timber tide]

Wrapping enums into its own namespace is something I've seen too, but I like to group classes who use those enums together.

[frigid sequoia]

So I basically just created a thing I can call from anywhere like any other method implemented in base unity right?

[timber tide]

As what you provided, if you don't wrap anything else in that namespace then at the top of the scripts that need to use those enums you'd have

using ProjectGeneralEnum```
As stated by PraetorBlue

[wintry quarry]

There's nothing special about it being in a namespace. It's just part of the name. Any class can be referred to from anywhere with or without a namespace

The only barrier to that would be if they're in different assemblies, which is a whole nother topic

[timber tide]

I just stink at naming stuff and I will run into reusing enum names, so without namespaces it wouldn't be possible

[chrome apex]

so I have the same error as yesterday, see screenshots with error and code:

I don't understand why. I referenced the class and the object in the inspector

[wintry quarry]

there's nothing on GameObject called play

[chrome apex]

but there is

[wintry quarry]

so it's clear you would get an error writing Play.play here

[polar acorn]

GameObjects do not have a function called play

[wintry quarry]

no there isn't

[chrome apex]

ok I will show you the script for that one

[wintry quarry]

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/GameObject.html
Nothing here called play\

[wintry quarry]

the script is irrelevant

your variable is a GameObject

not whatever script you're about to show us

[chrome apex]

omg I'm an idiot

[wintry quarry]

if you want to reference a script, you need to use that script's class name, not GameObject

[chrome apex]

I was referencing the object, not the class

that's why

sorry, I'm just a little bit mentally impaired

[frosty hound]

Didn't this happen yesterday?

[chrome apex]

yes it did lmao

yesterday it "fixed itself", maybe that's what happened

that's what happens when you name them the same thing

[dreamy rose]

guys i have a question how do i add custom meshe to my player

[polar acorn]

Add a MeshFilter if there isn't one, set the mesh to the one you want, and add a MeshRenderer if there isn't one

[swift crag]

this is pretty vague

[dreamy rose]

do we need t o have a mesh or can i import a fbx file from blender and use it as a player

[polar acorn]

That is a mesh

[dreamy rose]

when i use that mesh the camera doesnt align with it looks odd

its like i put the camera where it is and its like MILES OFF

[polar acorn]

This is an entirely different question

[dreamy rose]

my fault

its currently 1 am

[polar acorn]

Does your mesh contain a camera

[dreamy rose]

no

[polar acorn]

If so, remove it

[polar acorn]

Then adding a mesh would have no effect on the camera whatsoever

[dreamy rose]

is it possible for you to join vc with me so i acn show you its really hard to explain

[polar acorn]

no

[dreamy rose]

uh okay i can try screen recording

jsut let me set it back up

[swift crag]

you're asking a series of questions that make no sense

[lone thorn]

okay listen let me rephrase

[dreamy rose]

its hard to explain

[lone thorn]

cus its our project

right so we have a player model from blender

[swift crag]

Are you trying to import a rigged model into Unity to use as a player model?

[lone thorn]

an fbx rigged and everything

[dreamy rose]

yes

[lone thorn]

what we’re having trouble with is adding a custom mesh

and when we just use the base fbx

[swift crag]

i don't know what "custom mesh" and "base fbx" means here

[lone thorn]

the camera doesn’t allign with its position

[lone thorn]

you know how you can add a mesh renderer

[polar acorn]

And what are you doing to attempt to align it

[swift crag]

Why do you need to add extra mesh renderers?

Are you trying to, say, put a hat on the player?

[lone thorn]

we tried aligning it manually

it didn’t work out

[swift crag]

Explain your actual problem, not your attempted solution

[lone thorn]

it turned out so weird

[lone thorn]

…

[polar acorn]

Cameras don't do anything on their own. If you want it to align with something, you have to actually do something with it

[lone thorn]

we have that code already

but it seems detached from the player

its really hard to explain

[polar acorn]

Maybe show a screenshot or something

[dreamy rose]

IS IT possible for us to vc so we can show you because i cant really explain this well

[polar acorn]

no

[swift crag]

you need to coherently explain what you're trying to accomplish and what is happening

So far you've just said "custom mesh", but I have no clue what that actually entails

are you trying to completely replace the player model?

[polar acorn]

There are no voice channels in this server

[lone thorn]

it’s actually so fucking hard to explain trust me 😭

[swift crag]

are you trying to attach an object to the player?

Then you haven't tried to explain.

Tell me what you want to make your game do.

Do not include anything technical whatsoever.

Simply describe what the end-goal is.

[lone thorn]

we want the camera to be attached to the player in a first person perspective

[dreamy rose]

basically i followed a tutorial for a player camera for a fps game and he(YOUTTUBE GUY) used a capsule for the player model and i mwondering why when i imported my palyer model from blender and replaced the capsule the camera is disconnected from the body

does that make more sense

[swift crag]

Okay, so you used to have this:

• Player
  • Capsule

And now you have this

• Player
  • Some Model

[lone thorn]

yes

and the capsule

the camera works perfectly

but the model that we use

the we made

the camera is misaligned

[polar acorn]

Is your model actually in the right place

[dreamy rose]

yes

[lone thorn]

elaborate

[swift crag]

ensure that its local position is zero, yes

[dreamy rose]

or maybe not i think it is

[polar acorn]

If your camera is pointing at a position, is that position where you'd expect it to be on the mesh

[lone thorn]

nope

[polar acorn]

like, if you want it to point at the center of the object

is the center of the object where the camera is set to follow

[lone thorn]

okay so if i move the camera to the player’s head it’s not even attached to him

we see it from a third person pov

[dreamy rose]

yeah

[polar acorn]

then move the object so that it's where the camera is following

[dreamy rose]

how? it says the camera is on the model

[swift crag]

Did you parent the camera to the model prefab directly?

[slender nymph]

obligatory "use cinemachine"

[lone thorn]

yes

[polar acorn]

Then move the camera

[swift crag]

That's going to make the camera sit in a fixed location relative to the model prefab object

[lone thorn]

ohh wait

[swift crag]

It's not going to care about anything that the model is doing

[lone thorn]

the camera

[swift crag]

put the camera in the correct place instead of the wrong place

[lone thorn]

is in a parent object called camera holder

the player is a separate family

[dreamy rose]

yes\

[polar acorn]

This is why screenshots would be helpful

So we don't need to ask a bunch of questions about what objects are where

[dreamy rose]

alright give me a seconjd

[polar acorn]

Okay, so, playerCam is not a parent or child of the mesh at all

[dreamy rose]

yeah according to the video it makes it less buggy? if it would help i could send you the video i followed

[polar acorn]

So, it seems like you just want to move either it or the mesh so they're where you want them to be

[swift crag]

note that CameraPos is pointing backwards

[lone thorn]

when we do that it moved so weirdly

[swift crag]

the blue arrow is the forwards direction for that object

[lone thorn]

we move the camera slightly frontwards it goes a million miles front

[polar acorn]

I don't even know what cameraPos is doing

It has no scripts

and no one's posted any code

so I have no information as to what that object does

[dreamy rose]

camera pos is where its supposed to be

[polar acorn]

Okay, so then you should move that object to where you want the camera to be

[dreamy rose]

could i send you the video so you could see what i mean

the video is very short

[dreamy rose]

i did

[polar acorn]

Okay, so you want the camera pointed out of the back of this guy's head

[dreamy rose]

i flipped it

it did nothing

[polar acorn]

How about show the !code of what moves the camera

[tulip stag]

I wanna write code that parses this into a Json and parses Json into this. I know that SO can't be parsed into Jsons— should I turn it into a Monobehaviour, or should I add a "dummy" Monobehaviour to parse this into and then parse it into a json and vice versa?

[polar acorn]

ToJson should work on any Unity Object
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/JsonUtility.ToJson.html

[dreamy rose]

https://paste.mod.gg/kqqqqawpvbyc/0 like this?

[polar acorn]

Yes.

[wintry quarry]

POCO is fine - no need to make a MB or SO

MB or SO will make it more complicated

[tulip stag]

What's POCO, sorry?

[wintry quarry]

plain old C# object

just a regular class like you have

[dreamy rose]

https://paste.mod.gg/gqeyrkxutuvd/0

[wintry quarry]

oh sorry

you have an SO right now

[polar acorn]

Okay, nothing in this has anything to do with the player. This code just rotates the object it's on (and an orientation object) based on the mouse

[tulip stag]

Yes!

[wintry quarry]

put all that dataq in a regular serializable class

[polar acorn]

Ah, this one moves it

[wintry quarry]

and just make that as a field on the SO

[dreamy rose]

honestly wish i knew what your talkinga bout the video does explain it slightly but i only have a rough idea on how it works

[polar acorn]

So, every frame, you teleport the camera to this object's position, and you rotate the camera based on the mouse

[swift crag]

wouldn't that just spit out an instance ID

[dreamy rose]

oh i see

i still dont see why its not worki ng?

[polar acorn]

Meaning the end result is, you should have a camera that is fixed inside of this mesh's head and spinning around as you move the mouse

[swift crag]

Aha

[polar acorn]

Where does the camera actually end up

[swift crag]

I figured out what the actual problem is

The player model isn't rotating.

[slender nymph]

nah, only references to other UnityEngine.Objects are serialized as their instance ID

[swift crag]

A capsule is radially symmetric, so it was not possible to tell that the capsule wasn't rotating

[dreamy rose]

the first image\ shows how the camera looks like

[swift crag]

Ah, right.

The object itself can still be serialized meaningfully.

[polar acorn]

Can you show the cameraPos object from more than one angle

[dreamy rose]

ill try my unity is all jumbled up rn

[tulip stag]

Ok ok bet

[dreamy rose]

im not sure if this is what you meant but here

[polar acorn]

Okay, so, if there is no other code involved in movng the camera, with what you've shown, there is no way that this code could result in the camera angle you showed

Which object has PlayerCam and MoveCam

[dreamy rose]

well uh those are the only 2 pieces of code i wrote

[polar acorn]

Your camera is offset from the MoveCam object

It will always be this many units away from the camera position in the player:

Which is to the left and in front, and slightly above

[dreamy rose]

wait so i just need to change the position of that?

[polar acorn]

Much like this camera angle

[dreamy rose]

sorry i dont really understand

[polar acorn]

Yes

[dreamy rose]

okay

let me try

[polar acorn]

Since you are moving the parent object to the cameraPos object, this object's position will be the offset from that the camera is in

this had nothing to do with the model

[dreamy rose]

woooooooowwwwwwww okay

i slightly understand now

[polar acorn]

The position you see in the inspector is how far away the object is from its parent

[dreamy rose]

but this seems aligned with the model?

im sorry if im a bit slow

[polar acorn]

What is?

[dreamy rose]

the player cam

you said its offset right?

[polar acorn]

Yes

Offset by exactly this much

It is that many units away from this

[dreamy rose]

so i should make allt he positions 0?

[polar acorn]

X is left/right
Y is up/down
Z is forward/backward.

So, the camera is 2.82 units to the left of the guy's head, 1.47 units above the guy's head, and 2.87 units in front of the guy's head

[polar acorn]

Assuming you want it to be at exactly that position, yes

[dreamy rose]

ohhhhh

wow

okay

yeayh it worked

[polar acorn]

If this object's position were 0,0,0 then it would be at 0 units to the left, 0 units above, and 0 units in front

which would mean it's at that object's position

[dreamy rose]

yeah i understand now

thanks alot

[void dawn]

how do i make a weapon switching system , you know like most fps games

[swift crag]

that depends quite a bit on what a "weapon" even is in your game!

[polar acorn]

Change out the model you're rendering, and what kind of prefab your gun shoots

[frigid sequoia]

Okay, I know this is like a pretty rough ask, but since this feels like extremely hard to test out for all cases. I would love if some of you guys could check this to see if I made like some kinda of superobvious msitake https://pastecode.io/s/zz6o2woj

[swift crag]

oh man, status effect stacking

i remember doing this extremely wrongly about eight years ago

[void dawn]

i want something like quake or doom

[swift crag]

does your game have any weapons at all right now?

at its most basic level: get rid of the current weapon, then create a new weapon

[timber tide]

Status effect stuff is hard

You'd think coroutines be fine but sometimes you want to remove specifics and that's such a pain

[swift crag]

It's the stacking of a mixture of different effects that gets really annoying

when they have different rules (possibly multiple rules on different instances of the same effect)

[timber tide]

Well, having a good GDD fixes a lot of problems too ;p

knowing me I don't know what the heck I want most of the time

[void dawn]

yes a pistol and im trying to add an assault rifle , but i as of now i cant make the player pick up the assault rifle and switch it with the pistol

[frigid sequoia]

I do know what I want, I don't know how to code it properly half of the time lol

[swift crag]

perhaps you can start by just completely throwing out the pistol

[timber tide]

I'd wouldn't make it too complex and just get basic stacking with refreshing on application if anything then append to it later

[polar acorn]

What defines a pistol

what scripts, assets, etc. make up the whole of "Pistol"

[void dawn]

well i made a universal script for all weapons , and a model for the pistol and another one for the rifle

[polar acorn]

So, it sounds like you just wanna disable the pistol model and enable the rifle model. Then do whatever your script does to be a different weapon

[void dawn]

yes and be able to swap for other guns the player find in the game

[void dawn]

im having some trouble with that

[slender nymph]

#💻┃code-beginner message

[void dawn]

funny isnt it

[lapis yew]

nah i push it directly to an active Command panel

[nimble apex]

i have made a custom button on the inspector, this button is the only thing doing ,beware this is SOLELY on editor mode only, it will NEVER be in runtime mode:

1. clean up collection A
2. instantiate linked prefab, not unlinked instance
3. populate collection A with those prefabs
4. populate collection B with collection A

all this steps are in a single function, and it wont be called by anything in runtime or editor mode unless inspector button is pressed

now i gonna show u guys how i populate both collection

this is collection A , A is a Dictionary<GameObject,contentType>

    private Dictionary<GameObject,contentType> allGameObjects = new();

    public void RebuildContent()
    {
        allGameObjects.Clear();

        if (hasSubTitle)
        {
            GameObject spawnedObj = Instantiate(prefabs[0], transform);
#if UNITY_EDITOR
            PrefabUtility.ConvertToPrefabInstance(spawnedObj, prefabs[0], new ConvertToPrefabInstanceSettings(), InteractionMode.AutomatedAction);
#endif
            allGameObjects.Add(spawnedObj, contentType.Subtitle);
        }

        foreach (contentType element in spawningElement)
        {
            GameObject spawnedObj = Instantiate(prefabs[(int)element], transform);
#if UNITY_EDITOR
            PrefabUtility.ConvertToPrefabInstance(spawnedObj, prefabs[(int)element], new ConvertToPrefabInstanceSettings(), InteractionMode.AutomatedAction);
#endif
            allGameObjects.Add(spawnedObj, element);
        }
    ..... <- populate collection B```

this is collection B , i made "a list of lists" , because i need to show it on inspector i need to chain them as serializable

[Serializable]
public class AllStepObj_Value
{
    public List<GameObject> Objects;
}

[Serializable]
public class AllStepObjMap
{
    public List<AllStepObj_Value> Steps;
}```

this is how i populate it

        int counter = 0;
        
        objMapper = new();
        objMapper.Steps = new(new List<AllStepObj_Value>(){});
        objMapper.Steps[0].Objects = new();

        foreach (GameObject element in allGameObjects.Keys)
        {
            objMapper.Steps[0].Objects.Add(element);
        }```

all of these scripts did not involved "execute in edit mode", as they are fully driven by inspector button events

by pressing the button, it will do something like this on inspector

objMapper (collection B) , is actually populated like the code

but if i ever move to other scene and come back, all stuff i populated on objMapper will disappear

why tho?

assigning it by hands , dragging objects will reserve across scene, but not code ?

[slender nymph]

did you mark the object as dirty?

[nimble apex]

dirty?

i think i havent?

[slender nymph]

https://unity.huh.how/editor-extensions/serialisation/persisting-changes

[nimble apex]

ohhhhh

ty i will look at it

[scarlet skiff]

whats this?

[slender nymph]

seems like a visual studio issue not related to unity

[nimble apex]

            if(GUILayout.Button("Rebuild UI"))
            {
                Undo.RecordObject(parent, "populate objMapper");
                parent.OnRebuild();
                PrefabUtility.RecordPrefabInstancePropertyModifications(parent);
            }```

i used undo instead of setdirty, it seems better

this is on my custom editor script

worked , ty 👍

[last owl]

Is there any reason an if statement with the condition that a certain boolean is true can evaluate to true but nothing inside the if statement actually runs? I'm so stumped, I've put debug logs everywhere and everything up until the boolean changing from false to true happens, but nothing inside the if statement runs. I've checked and there are no spelling errors.

[frigid sequoia]

Why can I not assign this?

Like it doesn't slot

[slender nymph]

are you attempting to drag a scene object into a prefab?

[frigid sequoia]

I am trying to assign a component of a child inside the prefab into a script on the prefab

[slender nymph]

actually have you saved your code? because the slot shows TextMeshPro rather than TextMeshProUGUI

[frigid sequoia]

I did, yeah

[swift crag]

Perhaps you have a compile error.

The type name is, indeed, wrong

[frigid sequoia]

Oh, unless it's not compiling cause I have an error in other script wait

[swift crag]

(also, you can generally just use TMP_Text)

[nimble apex]

textmeshpro is different from UGUI, one is solely UI , one can be instantiated in world space

[slender nymph]

any compile errors will prevent all of the code from compiling

[swift crag]

TextMeshPro and TextMeshProUGUI have largely the same interface

i'm actually not sure what would differ from the outside

[nimble apex]

they are very close

[swift crag]

(hence why I always just use TMP_Text)

[nimble apex]

just import TMPro yes

and then u can use TMP_Text

[swift crag]

that's a given for any textmesh pro type

[frigid sequoia]

Doing a .Clear() on a dictionary is pretty much the same than just assigning it a whole new blank Dictionray right?

[wintry quarry]

No.

• if there are other references to the dictionary, Clear() will be visible to them. Assigning a new dict to this reference is not.

[north kiln]

One clears the dictionary, the other allocates and assigns a completely new instance

[frigid sequoia]

What do you mean visible?

[frigid sequoia]

And what's the difference betweena a cleared up dictionary and a new isntance of it with no data?

[wintry quarry]

I mean accessing the dictionary through those references you will find it has been cleared

[north kiln]

If a dictionary has previously been populated it may have grown, resizing its backing arrays to accommodate the data that was previously assigned.
Clearing that just resets that data, it remains allocated.

A new instance is unrelated new data that's only referenced where you newly assign it, and will have to reallocate space as it grows

[frigid sequoia]

So if I am making a new instance I am... liberating space?

[north kiln]

If the previous references to the old dictionary are set to null, sure. But whether it's liberating for a good reason or not is usually the driver to whether you new or clear

[wintry quarry]

I mean:

Dictionary<string, string> a = new();
a["hi"] = "hello";

// b is now another reference to the same Dictionary
Dictionary<string, string> b = a;

a.Clear();
Debug.Log(b.ContainsKey("hi")); // false

a["hi"] = "hello";

// here we reassign a to a new dictionary
a = new();

// b still points to the old one
Debug.Log(b["hi"]); // prints "hello"```

[north kiln]

if it's just gonna regrow then deallocating is a bad idea because garbage collection and allocation is not free

[frigid sequoia]

Would b update to a dinamically there? wouldn't it just be a copy?

[wintry quarry]

it's not a copy

they are both references to the same underlying object up until the part where a is reassigned

that's why we call them references

THere's only one dictionary

we are clearing the one dictionary

so both references can "see" the changes

[frigid sequoia]

Yeah, but wasn't your reference to a snapshoot of the state of the dictionray at one specific time and therefore not changed?

[wintry quarry]

no.

There is no snapshotting

both references are equal references to the one existing dictionary

That's the difference between a value type and a reference type

If it was a value type object, for example a Vector3 or an int, then it would behave as you say

[frigid sequoia]

I have read that like 10 times I do not understand it. Like how can I even tell them apart?

[north kiln]

https://unity.huh.how/value-and-reference-types

[frigid sequoia]

What if a wanted a snapshot of the DIctionary?

[north kiln]

var copy = new Dictionary<ExampleKey, ExampleValue>(otherDictionary);

[wintry quarry]

You would make a new dictionary and copy over all the values.

What vertx wrote just above me does that

note that when you want to actually create a new separate object we must use the new keyword

[wintry quarry]

there's nothing to tell apart, again they are the same object.

A reference variable (such as a and b in my example) is nothing but an address or pointer to a location in memory where the actual object lives.

[frigid sequoia]

Why declare it as var and not as Dictionary?

[wintry quarry]

in this case, both addresses are the same

[wintry quarry]

because my wife is sleeping on my arm and it is less typing

wait

sorry I didn't lol, only vertx did

it's less typing is all

[bright zodiac]

@frigid sequoia https://media.giphy.com/media/xUPGcLrX5NQgooYcG4/giphy.gif

[north kiln]

var copy = new Dictionary<ExampleKey, ExampleValue>(otherDictionary);
Dictionary<ExampleKey, ExampleValue> copy = new Dictionary<ExampleKey, ExampleValue>(otherDictionary);
Dictionary<ExampleKey, ExampleValue> copy = new(otherDictionary);

They're all the same, who cares how you write it

[bright zodiac]

see the gif animation about ref vs value type

should be easier to digest

[void thicket]

otherDictionary.ToDictionary()

[north kiln]

I hate that gif, why coffee, something that makes no sense to have a copy or reference of

[void thicket]

Yeah

It doesn't explain actual mechanism

[north kiln]

At least it explains the semantics, but yeah it makes me feel ick 😄

[bright zodiac]

y'all already explained it, some visuals reps would defo help

no need to say the same exact thing... waste of breath 😂

[frigid sequoia]

Yeah, I understand the concept, I just don't understand how it works

[wintry quarry]

I think of reeference variables as pieces of paper with addresses written on them. With the object being referred to as the house. itself

a = something; changes the address written on a

a.Clear() actually clears out the house at the address

so if a and b hold the same address, clearing out the house at address a will also clear the house at address b

since they're the same house

[bright zodiac]

that would not be true in the case of

Dict<T> dict = new():

Foo(ref dict); // that pass the address, not reference

[frigid sequoia]

So if I do this b would remain as 1 no matter what I do to a

[void thicket]

I hate to say this but learning C is easiest way to understand

[frigid sequoia]

What if I don't want it to?

[wintry quarry]

This doesn't change the analogy... this actually passes a reference to the piece of paper

[wintry quarry]

yes because int is a value type

assuming a was 1 when the emthod was called

[north kiln]

You could wrap it in a class and refer to the variable in the class, because the class is a reference type, passing the reference around is just passing around that address

[frigid sequoia]

So... if do like this u mean????

You need Time.deltaTime when you need to convert a per-frame quantity to a per-second quantity. Whether that's happening in a coroutine or not is irrelevant

public class SomeClass {
  public int Value;
}

public SomeClass A = new() { Value = 1 };

  SomeClass b = A;
  b.Value = 2;
  // a.Value is now also 2.

alright

well this seems to be not working correctly:

transform.localPosition = transform.localPosition+new Vector3(velocityX * Time.deltaTime, velocityY * Time.deltaTime, velocityZ * Time.deltaTime);

what are you expecting it to do

and what's happening instead?

[sacred cradle]

its like its really slow

and doesnt move at all

[sacred cradle]

and normally without Time.deltaTime its moving normally fast

[sacred cradle]

hold on

sorry, smth came up

ill be back in like an hour or two

[frigid sequoia]

Like do I have to know which ones do that of aiming at the same memory space rather than snapshooting?

[wintry quarry]

Yes you have to know but it's a very simple rule. If the type is a struct, it "does the snapshotting" i.e. it's a value type
if the type is a class, it's a reference type

[north kiln]

I feel this was pretty well explained in the resources linked

[frigid sequoia]

Maybe for you

I read that I am like "what?" on each other word

[north kiln]

Then please ask questions about what you don't understand, pointing to the paragraph in question

[frigid sequoia]

It's not anything in particullar

[north kiln]

as if the resource I've written is not enough I would like to improve it instead of just having endless pointless rehashings of things it already explains

[frigid sequoia]

It's like reading about a subject u don't really understand yet and you are like "wait, what was that again?" you know?

Like I dunno, I guess I am used to textbooks where 90% of the words are like actual filler

But I just understand something a thousand times better with a single practical example than reading the documentation 100 times

[sand snow]

how do I reference a script from a different script

[ivory bobcat]

Create a public or serialized field and drag-drop the other object with said component-script into the field from the inspector

[sand snow]

yup just found a 1 min tutorial, cant believe i didnt think of that

[ivory bobcat]

If you're needing a reference during runtime, when you instantiate the object you'd pass a reference to the instantiated object

[dense pike]

Can someone help me. I need a script that plays object animation on play trigger enter

[burnt vapor]

Look up the OnTriggerEnter method and Animation.Play. WHen the method is called, verify the object using its tag and call the play method.

[azure citrus]

hi i'm messing around a prefab i installed on asset store, and i'm trying to get it moving, but only its outline moves and not the object itself. does anyone know why

the script only moves the parent object so far

[barren rampart]

Hi does anyone have an idea what my be wrong with by character? I added a camera to follow it, but there seems to be a flickering in animations. I tried to record it, but it seems fine on the recording. Before I added the camera follow it was fine too.

[real thunder]

is your character a rigidbody without interpolation turned on?

if that's the case simply turn it on interpolate, if it's not you should probably share camera movement code

[barren rampart]

Oh yes thank you, that was the problem

I don't really know what that interpolation means

[real thunder]

yep, everyone getting bumped onto this issue

interpolation is when the value getting calculated between other values, I guess?
anyway
this specific case it means that gameobject is still moving inbetween physics frames
now it would visually lag one physic frame behind it's actual position, as a drawback, but it's almost always is fine
if it's not fine extrapolate exists but it can create another problem where the object appear further than it actually is within same 1 physic frame error

there are 50 physic frames in one second by default
but you can have more than 50 fps in one second
if you happened to get new visual frame without getting new physic frame
physically moving objects like rigidbodies won't move
and that would make an illusion of lag

if you pay close attention and have high fps you might be noticing it
it usually only a noticeable issue if a camera following such object

interpolation on rigidbody would add fake movement in between physic frames so it always move somewhat smoothly

fake in a sense you can't get collisions and stuff on such fake movement frames

[zinc shuttle]

i have a doubt, so i am making a 2D game where you can interact with the building to go in the building, but so many different buildings are there, should i use the load Scene method or anything better i can do here

[real thunder]

who knows what's going on with asset store assets
I don't think there are issues on the video I can spot, rather than if you move not the train but something else, like only it's collider idk

[real thunder]

you may consider keeping buildings out of bounds and teleport player in and out of them? idk

it's a general gamedesign question

is they are small and there is alot of them teleporting seems better, if not scenes

[barren rampart]

ahh I see

thanks for the explenations and for the help

have a good one

[teal elk]

How do I make my speed boost properly follow behind my player and not rotate with the player

[real thunder]

try simulation space global

so particles no longer exist as player transform childs (kinda)

[teal elk]

tried that still the same issue

[timber tide]

global space is correct to prevent them rotating after instantiating, but you need local direction upon instantiation to rotate them at the start

also #✨┃vfx-and-particles

[inland cobalt]

How does order of execution work with unity? For example will it wait for an entire Start() function to complete before mvoing onto the next, or do they happen semi in parallel? Same thing with stuff like FixedUpdate(), im getting some inconsistencies with my code and im wondering if that is the cause

[grand snow]

they are all executed one after another on the main thread. you can customise the execution order for monobehaviour events or you should manage executing methods yourself in an order you prefer.

[inland cobalt]

i see, ill look into that, thanks

[cold elbow]

using UnityEngine;

public class BallController : MonoBehaviour {
    public float speed = 10f;
    private int _scannerLayer;
    private Rigidbody2D _rb;

    private void Awake() {
        InitializeRigidbody2D();    
        InitializeScannerLayer(7);
    }
    private void Start() {
        _rb.linearVelocity = _rb.linearVelocity.normalized * speed; //set linear velocity
    }
    private void OnCollisionEnter2D(Collision2D collision) {
        var normalizedVelocity = _rb.linearVelocity.normalized * speed;
        _rb.linearVelocity = normalizedVelocity;
        
        if (collision.gameObject.layer == _scannerLayer) {
            Debug.Log("Ball detected colliding with scanner. Destroying Ball.");
            
            DestroyBall();
        }
    }
    
    private void DestroyBall() {
        Destroy(gameObject);
    }

    private void InitializeRigidbody2D() {
        _rb = GetComponent<Rigidbody2D>();

        if (_rb == null) {
            Debug.LogError("Ball Rigidbody component is missing on game object.");
        }
    }

    private void InitializeScannerLayer(int layer) {
        _scannerLayer = layer;
    }
    // Update is called once per frame

}

In oncollision2D in the if statement condition it always evaluates to false even tho I had already set up the game object layer properly on the unity inspector, I've tried everything it still doesn't work

[keen dew]

Debug.Log($"{collision.gameObject.name} collided, it has layer {collision.gameObject.layer}, scanner layer is {_scannerLayer}");

Put this outside the if statement and show what it prints

[hasty dragon]

im using the character controller component and theres no gravity

what do i do?

[wintry quarry]

1. Decide if you want gravity
2. If you do, simulate gravity yourself in your code.
3. Optionally use the SimpleMove function instead of Move, which has built in gravity

Almost any tutorial with Characteracontroller will cover how to simulate gravity though

[hasty dragon]

i see

[coarse magnet]

hey everyone, currently i have spawners in my project that spawns an enemy, how do i make it spawn a different enemy after a certain time?(the game is a plane shooter)(i have the timer set on a different script)

[wintry quarry]

Use an if statement?
Or put the things you want to spawn in some kind of list that you iterate over?

The question is pretty vague

[coarse magnet]

i know the method but idk how to implement it

like how do i change the variable inside a script midgame?

wait

i think i figured it out

[wintry quarry]

With the = operator

[coarse magnet]

yeah that 😅

[fast fern]

I switched to VS Code since it some auto completes for my code, but it seems like I'm still missing a lot of options
This is what I get:

these I don't see

I followed all instructions from here https://code.visualstudio.com/docs/other/unity
but I still can't seem to get all the other options

[wintry quarry]

Do you have variables or classes or methods with those names?

[fast fern]

don't have any

[wintry quarry]

Then why would they show up?

[fast fern]

wait me lost

I think those are the defualt?

[wintry quarry]

No

They're not default

Those are some custom classes and methods in wherever you took that screenshot from

LogicScript is not a default anything

[fast fern]

oh

dayum, I'm just super lost then

I'll try everthing again, thanks for your time

[cold elbow]

it keeps printing something else

it doesn't detect the collision with the layer I want it to

[wintry quarry]

What does it print exactly

[fleet venture]

why cant i assign this object to a field of type Camera

should i be using a diff type?

[cosmic dagger]

Are you dragging this from the scene onto a prefab?

[fleet venture]

yes

and its a static field

[cosmic dagger]

A prefab cannot reference scene GameObjects . . .

[fleet venture]

so then how do i do it

[cosmic dagger]

Huh? Static fields don't display in the inspector . . .

[fleet venture]

they do

it is

[real thunder]

nonononono, they don't

[cosmic dagger]

Show us . . .

[real thunder]

unity don't support serializing of static fields

or something like that

[fluid remnant]

static field belongs to the class not the instance thats why

[fleet venture]

oh wait the editor wasnt updating because my code had other errors

but then what if i want it static

ye i want this shared for all instances of the class

i cant do Camera.main because thats expensive apparently

[cosmic dagger]

That's fine. It can be static, but you have to assign it manually via code . . .

[fluid remnant]

You can make the class itself have a static instance

[fleet venture]

how do i get it from the scene tho

[real thunder]

GameObject.Find worst case

[fluid remnant]

no

[fleet venture]

well i would rather have a best case

this is a prefab tho if that matters

[fluid remnant]

use a singleton pattern or Dependency Inject it

[fleet venture]

a singleton makes no sense here

[real thunder]

this case I would use a singleton holding references

[fleet venture]

i mean it doesnt HAVE to be static

[real thunder]

it's not great I agree

[fleet venture]

but it does make my life a lot easier

[real thunder]

make it static, make it non static, assign non static to static on Awake?

[fluid remnant]

without explaining the use case is not really productive to suggest anything

[real thunder]

fair

[fleet venture]

ok i just want a draggable object

[cosmic dagger]

There are a few methods. Dependency injection works well; when instantiating the object, the script that creates it can have a reference to the object you need . . .

[fleet venture]

this is what i have so far

public class DraggableObject : MonoBehaviour
{
    private bool _dragging = false;
    public static Camera MainCamera;
    
    private void Update()
    {
        if (!_dragging) return;
        var mousePosition = MainCamera?.ScreenToWorldPoint(Input.mousePosition);
        if (mousePosition == null) return;
        transform.position = new Vector3(mousePosition.Value.x, mousePosition.Value.y, 0);
    }
}```

i had Camera.main first but thats expensive

[fluid remnant]

all this for a camera?

[fleet venture]

i got a warning

ye

the main camera

[fluid remnant]

just cache camera in awake with camera.main

[fleet venture]

oh

idk what awake is

[rocky canyon]

camera.main isn't that expensive as a matter of fact

[fleet venture]

but ig that works

[fluid remnant]

its the initialization method

[fleet venture]

well my ide says it is

[rocky canyon]

it used to be

[cosmic dagger]

You can't use ?. with MainCamera because it's a UnityEngine.Object . . .

[fleet venture]

Lazy is a cache right?

[fluid remnant]

it used to be much more expensive that it is these days

[fleet venture]

? wdym

its nullable

its not

[cosmic dagger]

Use Camera.main to get the main camera in Awake or Start . . .

[fleet venture]

its an artifact from what i had first

[fluid remnant]

Unity Objects cannot be null checked his way

[fleet venture]

bruh why not unity has so many weird quirks

[fluid remnant]

they are internally handled

[fleet venture]

so i cant get a NRE?

[cosmic dagger]

It doesn't matter. Unity objects do not support the newer null conditional or coalescing operators . . .

[deft breach]

Just assign the Main Camera in Awake its 1 time call pretty cheap

[fleet venture]

ok

[fluid remnant]

After the underlying component is destroyed, the C# object for the
MonoBehaviour remains in memory until garbage is collected. A MonoBehaviour in this state acts as if it is null. For example, it returns true for a "obj == null" check. However, this class doesn't support the null-conditional operator (?.) and the null-coalescing operator (??).
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/MonoBehaviour.html
The null-conditional operator (?.) and the null-coalescing operator (??) are not supported with Unity Objects because they cannot be overridden to treat detached objects objects the same as null. It is only safe to use those operators in your scripts if there is certainty that the objects being checked are never in a detached state.
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Object.html

[deft breach]

private void Awake() {
MainCamera = Camera.main;
}

[fleet venture]

ye i got it

[real thunder]

wait if obj == null is true how can ?. not be supported; it's the same thing in my head ><

[cosmic dagger]

Because Unity overrides the == operator . . .

[real thunder]

oh

it's worse than I thought

[rocky canyon]

Game engines are incredibly powerful software, handling a vast number of systems that all need to work together seamlessly. With so many moving parts, there are countless quirks and complexities that make them challenging to fully grasp.

game-engine lyfe

[fleet venture]

btw i cant get the OnMouseDrag to work properly

like its really buggy

is that like a known thing?

[fluid remnant]

those methods don't work very well

[fleet venture]

ok so i should just create my own thing with OnMouseEnter Exit Down and UP?

[fluid remnant]

event system has better ones or just make your own raycast behaviour

[fleet venture]

what im not about to create a full raycasting system

[rocky canyon]

ive always wrote my own drag and drop mechanics using the pointer interfaces

[fleet venture]

im a beginner in unity T-T

[fluid remnant]

raycasts are built in

[fleet venture]

and my teacher said the event system only works with UI components

[fluid remnant]

your teacher is wrong

[cosmic dagger]

Just use the IPointerEvents . . .

[rocky canyon]

event system works w/ anything w/ a collider

yea ur teacher must not be a very great teacher

[fleet venture]

you mean the EventTrigger component right?

[fluid remnant]

you can add Physics raycaster and it works with colliders

[rocky canyon]

Graphics Raycaster innit?

[fluid remnant]

Physics Raycaster

[rocky canyon]

ahh ok

[fluid remnant]

I believe graphic is for canvas

[fleet venture]

i have no idea what to do

so using OnMouseEnter and stuff also wont work?

[fluid remnant]

perhaps you should show what exactly isn't working

[fleet venture]

how do i show it

like a video?

[fluid remnant]

what is the intended behaviour vs what is currently happening?

[fluid remnant]

sure

[fleet venture]

i already changed it away from the OnDrag though

[deft breach]

this maybe a working method of doing it: https://stackoverflow.com/questions/56435180/how-do-i-drag-objects-on-the-screen-using-onmousedrag

[fleet venture]

one second

[cosmic dagger]

It will work, if done correctly . . .

[fleet venture]

eh it works but if i move my mouse too fast it doesnt

because then it exits

and it stops

[fluid remnant]

are you doing drag and drop? just enable and disable a bool and use update to follow

[fleet venture]

thats what im doing

it doesnt work

i made a video hold on

[fervent abyss]

is there an event to track text changes in textmeshpro?

[fleet venture]

First of all i cant drag it out of the menu, i have to rregrab it.
Second of all if you move your mouse too fast it breaks

[fluid remnant]

if you're setting the changes to the text, you already can track it. Use an event

[fervent abyss]

well im changing the text from 2 scripts that do 2 different behaviours

[cosmic dagger]

Instead of assigning the text: text = "blah", create a method with a parameter and pass in the text. Within the method, change the text and invoke an event . . .

[fluid remnant]

there is obviously more complicated stuff going on here then you're letting off, you are dragging UI items into sprites or they stay as canvas items?

[fleet venture]

this is the code btw ```c#
public class DraggableObject : MonoBehaviour
{
private bool _dragging;
private bool _mouseDown;
private static Camera _mainCamera;

private void Awake()
{
    _mainCamera = Camera.main;
}

private void Update()
{
    if (!_dragging || !_mouseDown) return;
    var mousePosition = _mainCamera.ScreenToWorldPoint(Input.mousePosition);
    transform.position = new Vector3(mousePosition.x, mousePosition.y, 0);
}

private void OnMouseEnter()
{
    _dragging = true;
}

private void OnMouseExit()
{
    _dragging = false;
}

private void OnMouseDown()
{
    _mouseDown = true;
}

private void OnMouseUp()
{
    _mouseDown = false;
}

}```

[fleet venture]

im dragging them into sprites

i create a new sprite from a prefab at teh mouse position

on mouse down on the ui element

[fluid remnant]

create a method that you use to change the text only through this component so you can invoke an event while doing so

[fleet venture]

then i would like to be able to drag it until mouse up

[fluid remnant]

thats why you have to click twice no?

you have to instantiate the new prefab as already set to follow mousePosition

[fleet venture]

ah

[fleet venture]

THat fixed it sort of, but now it keeps moving after i release the mouse button

even tho i have the event for it

[fluid remnant]

you'd have to show the code and what you did

[fleet venture]

public void AddObject(GameObject instance, bool isBackground)
    {
        gameManager.IncreaseObjectLayer();
        var mousePosition = Camera.main?.ScreenToWorldPoint(Input.mousePosition);
        if (mousePosition == null) return;
        instance.transform.position = new Vector3(mousePosition.Value.x, mousePosition.Value.y, 0);
        var prop = instance.GetComponent<Prop>();
        prop.SetDragging();
    }```

public void SetDragging()
    {
        _dragging = true;
        _mouseDown = true;
    }```

[fleet venture]

and this

[fluid remnant]

so dragging stays true?

[fleet venture]

apparently

[fluid remnant]

why not set it to false in OnMouseUp

[fleet venture]

dragging checks if you rmouse is over the object

its meant to stay true when you just rleease the button

but it also checks if mousedown is true

which shouldnt be true as i set that false in OnMouseUP

[rancid tinsel]

what does this mean?

[rocky canyon]

ur calling the class itself

not an instance of it

[fluid remnant]

is Instance actually static?

[rocky canyon]

^ check that

[rancid tinsel]

it is

so is currentPoolSize though maybe that's the issue

[fluid remnant]

yes

[deft breach]

there you have it: https://docs.unity3d.com/6000.0/Documentation/ScriptReference/MonoBehaviour.OnMouseEnter.html Every time the Mouse is just Over your object dragging is set to true so its always gonna be true

[rancid tinsel]

the idea was to have it not change from outside the class

but be readable

[fleet venture]

who made that naming

[fluid remnant]

why is it static though if you have static instance

[fleet venture]

i though tit was only when entering

then how do i do this

[rancid tinsel]

oh wait i dont need static for the setter

[cosmic dagger]

You're accessing currentPoolSize through the Instance field which is an instance of SFXPool. you need to access it straight from the class itself . . .

[fleet venture]

so OnMOuseEnter is called repeatedly?

[fluid remnant]

if you keep it static it would be
SFXPool.currentPoolSize

[fleet venture]

well either way shouldnt the exit set it to false and then its not true anymore

untill you reenter it

[rocky canyon]

if u would debug the values ur using u'd understand alot more of whats happening and just Debug in general

[deft breach]

When your Mouse is over the thing yes

[rancid tinsel]

ok so just to confirm if i understand how this works correctly - get is public, meaning it can be accessed from anywhere, but set is private meaning it cannot be changed from outside the class?

[fluid remnant]

yes

[rancid tinsel]

ok thank you!

[fleet venture]

well idk how im meant to debug this if i need my mouse to test it

[rocky canyon]

tf u talkin about? debugs show in the console window

[fluid remnant]

Debug like everyone else does use Debug.Log

[fleet venture]

oh i always use breakpoints

oh btw

[fluid remnant]

or if you want to see them on Screen you can also use GUI.Label in IMGUI

[fleet venture]

ive not figured out how to get the consoel window open without an error message showingup

[fluid remnant]

if you have error you should probably take care of those..

[fleet venture]

no no, i mean i can only open it IF i have an error

cuz then i can click on the error to open it

but if i have no error idk how to open it

[rocky canyon]

you 💯 wanna fix that..

[fluid remnant]

there is separate tab for it

[rocky canyon]

ur gonna have abad time building an entire game w/o the ability to check the console logs

[fleet venture]

ah

[rocky canyon]

put logs in everything.. every method.. ever function. all that stuff.. then play the game as usual..
then u can watch and pay attention to what logs show and WHEN

it'll 💯 help ur understanding

[fleet venture]

oh

ye ive always used breakpoints

but thats a bit hard with this

[rocky canyon]

those are great too..

but yea simple debugs wuld be better in this situation

where ur just trying to observe the flow and whats actually being called

[fleet venture]

ok nah this works how i expect it to work

[fluid remnant]

you can also do onscreen debugging if you feel brave to use IMGUI

    private void OnGUI()
    {
        GUI.Label(new (0,40,100,25), $"bool {mybool}");
    }```

[fleet venture]

it only calls it when it enters it

[rocky canyon]

its nice to know for sure right?

🫠

[fleet venture]

true

OnMouseUp doesnt get called

can that not be called if OnMouseDown isnt called or something?

[deft breach]

Maybe if you just try simplifing it at first:

    {
        gameManager.IncreaseObjectLayer();
        var mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
        if (mousePosition == null) return;
        instance.transform.position = new Vector3(mousePosition.Value.x, mousePosition.Value.y, 0);
    }```

Then remove the SetDragging and change the Awake Method:
``` private void Awake()
    {
        _mainCamera = Camera.main;
        _dragging = true;
    }```

And lastly, also remove OnMouseEnter() and OnMouseExit()
Dont know if this works buy you could give it a try @fleet venture

[fleet venture]

there is literally no dragging code here though

[rocky canyon]

sounds plausible to me

[fleet venture]

wait nvm

[deft breach]

thats in the update i thought

[fleet venture]

ye it is

[grand snow]

Are you using the input system pointer events or the mouse messages?

[rocky canyon]

but tbh it seems like OnMouseUp would still get called even if it misses the Down

[fleet venture]

no idee

[fleet venture]

removing the mouse enter and exit does fix an issue

so its definetly better

but it doesnt fix the mouse up problem

[rocky canyon]

#💻┃code-beginner message

[fleet venture]

well i checked it with Debug.log and its not getting called

[rocky canyon]

yea i was just guessing.. as i havent ever relaly had code like this

[deft breach]

and you only set dragging to true in MouseDown and Awake right?

[rocky canyon]

theres always a down when theres an up lol

[fleet venture]

no i also call it here

public void AddObject(GameObject instance, bool isBackground)
    {
        gameManager.IncreaseObjectLayer();
        var mousePosition = Camera.main?.ScreenToWorldPoint(Input.mousePosition);
        if (mousePosition == null) return;
        instance.transform.position = new Vector3(mousePosition.Value.x, mousePosition.Value.y, 0);
        var prop = instance.GetComponent<Prop>();
        prop.SetDragging();
    }```

in SetDragging

i just set booth bools to true in there

i geuss i only need 1 bool now tho

[grand snow]

I always use the event system drag events with a physics raycaster for things like this:
https://docs.unity3d.com/Packages/com.unity.ugui@3.0/api/UnityEngine.EventSystems.IBeginDragHandler.html

[fleet venture]

that sounds quite complicated

[rocky canyon]

same..

[fleet venture]

physics raycaster?

[rocky canyon]

good stuff

[grand snow]

Its not. you implement the begin drag, drag and end drag handlers, put a collider on your gameobject and add the physics raycaster to the event system

[rocky canyon]

hella useful interfaces

[fleet venture]

i just implement those and it works?

[grand snow]

https://docs.unity3d.com/2022.3/Documentation/Manual/script-PhysicsRaycaster.html

[rich adder]

just keep in mind with this, UI elements can block your Raycasts

[fleet venture]

oh

[rocky canyon]

as long as u have the raycaster component and an event system

[fleet venture]

so how do i fix that then

i mean

i want this object spawned above it anyways

wait thats not possible

💀

is that possible?

[rocky canyon]

isnt learning fun 🙂

[rich adder]

You can put camera mode to Screenspace camera and set certain plane so sprites can be above

[fleet venture]

do you just mean this event system?

[grand snow]

Its good when you want say a UI button to be usable and not trigger drags for things "behind it"

[rocky canyon]

yes that event system

[swift crag]

By default, it only provides UI events

But it can also provide the same set of events for objects with colliders

[fleet venture]

ohh ye my teacher said that wasnt possible

ig he was wrong

[swift crag]

i would have said the same until about uh

3 days ago, haha

[grand snow]

Yea, adding the physics raycaster or physics 2d raycaster makes these events work with 3d and 2d colliders
