See, something I wasn't aware of lol

[swift crag]

okay, so this is Visual Studio

[rich adder]

yeah that not configured

[hexed terrace]

!vs

[eternal falcon]

Visual Studio guide

If your IDE is not underlining errors in red or autocompleting code,
please configure it using the link below:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)

[mild osprey]

This is just what I went off of a youtube video as one option

[swift crag]

drums tried to configure the code editor already and had a problem

[cosmic dagger]

ok, now compare this to the unity/youtube code to see where you went wrong . . .

[mild osprey]

Well then glad I came to ask because I was not aware of that at all

[rich adder]

there ya go , btw IDE configuration is part of Unity Programming Path

[summer stump]

If MonoBehaviour (and all those types) is white, it is not configured
(Unless you forced it to be that way in settings)

[rich adder]

https://learn.unity.com/tutorial/set-your-default-script-editor-ide

[mild osprey]

Well I went through everything on that section and thought I did everything step by step and correctly.

Alright time for me to go fix some stuff.

[summer stump]

Show your workload, the external tools menu, and package manager

[noble summit]

make sure preferences -> external tools has the correct version

[swift crag]

You said something about the choice of script editor resetting.

[toxic frigate]

Lessgo the SO works now

[mild osprey]

Sorry, which part is workload? I know external tools and package manager.

The script?

[swift crag]

this would be a screenshot of Visual Studio

showing that you have the Unity workload installed

this is described in the instructinos

[summer stump]

Workload is something you do inside Visual Studio
Edit: ah, as fen said

[mild osprey]

Guess it's time to reread the basics again lol

[night sparrow]

Could anyone help me Im not sure if this a code Issue or something else, my Player seems to just fall through the map since using Pun 2 Networking and setting it up!

Not sure if i have done something wrong with player or what

[summer stump]

Missing a collider?
Dunno how PUN works, but I see a rigidbody and no collider

[night sparrow]

Not sure, never had one before it worked fine

[polar acorn]

If you had collisions before, you had a collider

[summer stump]

Was your rigidbody always dynamic? Or was it kinematic

[polar acorn]

Note that a CharacterController is a collider

[toxic frigate]

prolly a dumb question but 2 SOs can have the same order right (since its kinda just priority level of execution)

[night sparrow]

I had CharacterController , so this is why when i removed it, that has caused it to fall through as No collider

[polar acorn]

What do you mean by "order"?

[summer stump]

So you removed the collider and added gravity. Seems a clear cut case here

[toxic frigate]

the order at the end

[swift crag]

This has nothing to do with execution order

It controls where they appear in the Create Asset menu

[toxic frigate]

ohhhhh

[swift crag]

you can find this out by reading the CreateAssetMenu documentation (:

[toxic frigate]

mb then

[swift crag]

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

[toxic frigate]

I was skimming through the SO section on their website so must've missed it

mb

Different filename, menuname and order, what exactly is being duplicated here between 2 different SOs

[swift crag]

none of those matter at all

the only thing that matters is the class name

the C# compiler doesn't care about the attribute at all, and filenames are also irrelevant

you can have 1,000 classes whose CreateAssetMenu attribute all give them a menuName of "Foo"

it'll compile just fine

[toxic frigate]

i see

[mild osprey]

But I'm already going back through the steps

Just sending you thiose anyways

[summer stump]

Ok, you didn't show the workload though
The workload is where you get the Unity "extension" (not called that in VS) inside Visual Studio

[swift crag]

how do you pull that window up if you installed VS through the Hub?

it looks like the instructions say to open it with the installer, which isn't relevant in that case

I don't use VS so I don't know off the top of my head

[summer stump]

At the top there is a menu called tools, and inside you click get tools or something

It's been a while, can't remember honestly

Maybe it actually says Get Extensions?

[languid gyro]

idk how to use this api

[swift crag]

you should probably read the Game Jolt API documentation, then

It looks like this is a component that has a single UnityEvent on it

which will fire upon...auto login!

presumably when the player is automatically logged in to something

[mild osprey]

Oh my, don't remember how I forgot this step. I did this last time on my wife's computer

[toxic frigate]

this is gonna be a dumb asf error but

SO1:

[CreateAssetMenu(fileName = "EntityConfigs", menuName = "Configs", order = 1)]
public class SpawnManagerScriptableObject : ScriptableObject
{

    [field: SerializeField] public float PlayerForce { get; private set; }
    [field: SerializeField] public float ObsSpeed { get; private set; }
    [field: SerializeField] public float ProjSpeed { get; private set; }
    [field: SerializeField] public float ObsDeadzone { get; private set; }
    [field: SerializeField] public float ProjDeadzone { get; private set; }

}```

SO2:
```using UnityEngine;

[CreateAssetMenu(fileName = "EntityStats", menuName = "Stats", order = 1)]
public class SpawnManagerScriptableObject : ScriptableObject
{

    [field: SerializeField] public float maxhp { get; private set; }
    [field: SerializeField] public float minhp { get; private set; }

}```

Error:
Duplicate 'CreateAssetMenu' attribute

what is the duplicating CreateAssetMenu attribute between the 2

[rich adder]

this is not required section , at all

[swift crag]

again, the class names are the same

they're both called SpawnManagerScriptableObject

so you have two [CreateAssetMenu] attributes on a class named SpawnManagerScriptableObject

hence the error

[rich adder]

the workloads something entirely different

[swift crag]

you'll need to point drums to that window, then

[rich adder]

its part of the guide

[swift crag]

the instructions cover how to open it when installing VS manually

they do not tell you how to open it if you aren't using the VS installer

[mild osprey]

But he said in Extensions in VS right?

[swift crag]

Did you install VS manually?

[rich adder]

there are no VS Extensions

[swift crag]

(probably because you shouldn't have to open that window at all if you installed it through the Hub)

[mild osprey]

Drums is trying to walk before he crawls 😬

[swift crag]

i dunno

[toxic frigate]

rahhhh finally got it (such a dumb one)

[mild osprey]

I'm on Visual Studio and theres an extensions tab, unless you mean something else

[toxic frigate]

thanks for bearing with me lol

[swift crag]

i need a one-word answer to this question: yes or no

[rich adder]

https://learn.microsoft.com/en-us/visualstudio/gamedev/unity/get-started/getting-started-with-visual-studio-tools-for-unity?pivots=windows#install-visual-studio-and-unity

[swift crag]

If you installed it manually, then you downloaded the Visual Studio installer. Use that to check that you've installed the Unity workload.

[languid gyro]

what's the next step for the Gamejolt UI?

[swift crag]

I have absolutely no idea what you're doing

most people here aren't going to know how the Game Jolt API works

[mild osprey]

Ok, brains working now

[swift crag]

So "game development with Unity" was already checked, correct?

[languid gyro]

ok hold on

[rich adder]

VS doesnt install without VSInstaller

[mild osprey]

Yes

[swift crag]

there's one really goofy problem you might be having

[mild osprey]

I haven't checked anything else since install

[swift crag]

sometimes VS just turns off the project

i believe you want the "Solution Explorer" window

[rich adder]

did you show the External Tools page already

[swift crag]

#💻┃code-beginner message

the old VSCode extension is installed, but that shouldn't matter

[mild osprey]

This one right

[rich adder]

2019 😬

[rich adder]

click regen project files, open script from unity again

screenshot the whole VS including Solution Explorer

[swift crag]

(and kill VS before you regen the project files)

this is the "turning it off and on" part of the diagnostic

[mild osprey]

"Regen proj files" is donde?

[polar acorn]

The button that says regenerate project files

[mild osprey]

On VS or Unity?

[mild osprey]

Oh.

[rich adder]

If it doesnt work after that and opening script, then in Solution Explorer def holds the issue

[night sparrow]

[night sparrow]

mb sorry!

[mild osprey]

Mother of God

[hexed terrace]

what?

[mild osprey]

Look above you my friend

My code imploded

[hexed terrace]

right, because you made a silly mistake

[mild osprey]

I'm sure I did I've been trying to fix my booboo

[rich adder]

well at least now its configured

[hexed terrace]

you seriously can't immediately tell what you did wrong?

[mild osprey]

Hold on let me look this over for a second

[rich adder]

member variables must be declared INSIDE a class

also wttf is -500 for

[hexed terrace]

reverse speed!

[rich adder]

going zoooooom

[mild osprey]

Idk, was just doing what one video suggested. Was trying to remember how to make it spin without looking up any hints, got stuck, started from scratch and watched the first youtube video to at least try

[rich adder]

probably want to use Time.deltaTime for consistency through different FPS

[slender nymph]

what you don't want to rotate 500 degrees per frame?

[mild osprey]

I'm sure once my dumbass actually either figures it out or is finally shown it's gonna hurt

[swift crag]

Anything in Update will execute once per frame.

So, you should keep that in mind when deciding how much rotating to do.

[mild osprey]

Exactly, I don't need smooth.

jk

[swift crag]

Imagine that the game is running at 100 frames per second

How many degrees should you rotate per frame to rotate at 500 degrees per second?

[mild osprey]

Is this an actual math question you're asking me? 😅

[swift crag]

Yes.

You're going to be doing a lot of math.

[mild osprey]

I know. Unfortunately. I'm getting ready to take some college classes soon for Math

[swift crag]

This is a middle-school algebra problem.

so, how many degrees per frame?

[mild osprey]

Well then I need a refresher course for that too.

[mild osprey]

Umm..one sec

[polar acorn]

https://simple.wikipedia.org/wiki/Division_(mathematics)

[rich adder]

did you fix your original problem first ?

[swift crag]

now that's an incredible embed

[polar acorn]

Yeah it is a bit l o n g isn't it

[mild osprey]

I have not yet. Trying to figure it out first before I come back cryin for help lol

[mild osprey]

I'm sure this stuff should be easier than how I feel right now. Once I actually get the hang of it though I'll remember how to fix my errors

[swift crag]

no, that would be for 60 frames per second

i specified that the game was running at 100 fps

wrong direction

500 divided by 100 is 5.

[mild osprey]

My guess would've been 100. I really need to refresh 😬

[swift crag]

500 degrees per second. 0.01 seconds per frame.

500 * 0.01 = 5

Multiplying 500 by Time.deltaTime will give you how far to rotate in each frame. Time.deltaTime is how long the last frame took to render.

At 100 frames per second, Time.deltaTime is 0.01, because each frame takes 0.01 seconds

Since your framerate will be varying, Time.deltaTime ensures that you rotate by the correct amount each frame.

[mild osprey]

Ok well I fixed all the code errors but propeller is still not spinning so going back over it and figuring that part out

[rich adder]

debug.log that the script is running

[mild osprey]

you are telling me to "start debugging" or something else?

Also I assume there's other better ways to learn all this lingo and terminology than Unity Learn? I don't want to limit myself

[earnest atlas]

I want to check for enemy aggro, I think of adding a sphere with OnTrigger that is set to player layer and check OnTriggerEnter to check if enemy should be in aggro state.

Or should I do it with Physics.SphereCast() that is run in corutine every few seconds?

[swift crag]

https://unity.huh.how/debugging/logging/how-to

[sweet osprey]

i think they mean to write a line of code in the script like "Debug.Log("Hello")" to see if it shows up in the unity console (and thus proves that the script is actually running)

[rich adder]

those physics queries are kinda expensive regardless why do you need casting anyway? best to keep them inside a list and iterate through them to find info

if you do use SphereCast , always opt for -nonalloc

[mild osprey]

Ah.

[earnest atlas]

So what would you recommend? Mesuring distance between enemies and player?

[mild osprey]

It does in fact print "Hello World"]\

ahh silly fingers

[pine bone]

Hello, how can i make 2 child objects teleport to the same position? I have an attachment system where the player can connect attachments together. I want to set 2 attachments to the same position and rotation while the parent follows it

[slender nymph]

print something meaningful, not useless text
https://unity.huh.how/debugging/logging/how-to

[rich adder]

I meant, if you're enemies are in a list already a distance check would prob be less expensive than quering for physics colliders

but I thought you want to check aggro, then use physics queries

just use nonalloc

[earnest atlas]

Im already doing one direction check to make a raycast that works as LOS trigger. Might as well before normalizing the vector calculate distance

Enemies are not in the list only player is. I get get player position and enemy position and just calculate the distance.

I have NavMechAgent thing. Maybe it has some implementation already?

[grave forge]

i need heeelp

[astral cedar]

what

[polar acorn]

https://dontasktoask.com/

[grave forge]

so i tried to do an fps game but camera dosent work

[upper sphinx]

How are you setting up the camera

[grave forge]

bro i swer if i get hit by this again

[grave forge]

uhh using an script

[polar acorn]

Maybe you should actually ask your question first then

[pine bone]

Can someone help please

[grave forge]

so my camera is there but its not fps yknow

[rich adder]

What exactly do you want to do

I'm kinda lost now lol

[polar acorn]

Set the position of both objects to the same value

[pine bone]

Did you actually read the question

[upper sphinx]

@grave forge so you want your camera to look around with the mouse or what you mean exacltly

[polar acorn]

Did you?

how can i make 2 child objects teleport to the same position?

[grave forge]

yea first person cam thats what i want

[pine bone]

and rotation while the parent follows it

[swift crag]

you're going to need to provdie more information if digi's answer is insufficient

[earnest atlas]

Well I need enemy to pursue player when its nearby and has LOS to it.

[polar acorn]

You can set rotation too. And parents don't "follow" child objects, other way around

Visual Studio Code guide

If your IDE is not underlining errors in red or autocompleting code,
please configure it using the link below:

https://on.unity.com/vscode

[lusty girder]

Why might the player rotation code under //Rotation work perfectly fine with AddForce but not with AddRelativeForce?
When 'AddRelativeForce' is used (_rigidbody.AddRelativeForce(_playerCalculatedForce, ForceMode.Force); in conjunction with the code under //Rotation, the player rigidbody starts moving in random directions.

private void FixedUpdate()
    {       
        _playerMoveInput = moveDirection;
        _playerCalculatedForce = _playerMoveInput; 
        _playerCalculatedForce = _playerCalculatedForce * _movementMultiplier;
        _playerCalculatedForce *= _rigidbody.mass; 

        _rigidbody.AddRelativeForce(_playerCalculatedForce, ForceMode.Force);
        //_rigidbody.AddForce(_playerCalculatedForce, ForceMode.Force);

        //Rotation
        if (MoveIsPressed)
        {
            targetRotation = Quaternion.LookRotation(moveDirection); //or moveDirectionRaw
            targetRotation = Quaternion.RotateTowards(transform.rotation, targetRotation, rotDegPerSecond * Time.deltaTime);
            _rigidbody.MoveRotation(targetRotation);
        }
    }

Full movement script (it is pretty small):
https://hastebin.com/share/abalotunan.csharp

[earnest atlas]

Agent has the code to chaice. I need distance and LOS chrcks

[upper sphinx]

@grave forge Unity has an FPS template already built-in into the Hub

[swift crag]

because AddRelativeForce works in local space

and AddForce works in world space

[grave forge]

Oh

[earnest atlas]

There is unity asset pack

[grave forge]

well time to delete my project i guess

[earnest atlas]

That comes with FPS controller

[swift crag]

in local space, Vector3.forward is whatever direction you're facing. in world space, Vector3.forward is a consistent direction (world forward)

[rich adder]

I usually do a Dot product for FOV and Raycast to check for barriers / obstacles

[earnest atlas]

Gonna look into dotproduct

[grave forge]

wait where is the template at

[lusty girder]

Then is there some way to convert _rigidbody.MoveRotation(targetRotation); to be AddRelativeForce- friendly?

[astral cedar]

FixedUpdate is the new version of Update()?

[swift crag]

i don't understand your question

[rich adder]

https://docs.unity3d.com/ScriptReference/Vector3.Dot.html
https://www.falstad.com/dotproduct/
https://www.geogebra.org/m/Yu6869By

[swift crag]

the problem with using AddRelativeForce instead of AddForce is that your input is being interpreted in a different coordinate space

[grave forge]

where

[swift crag]

this has nothing to do with using MoveRotation to change your rotation

[polar acorn]

It's not new, it's the physics update step
https://docs.unity3d.com/ScriptReference/MonoBehaviour.FixedUpdate.html

[verbal dome]

AddRelativeTorque/AddTorque is for rotation

[swift crag]

well, other than the fact that changing your rotation changes the meaning of a local-space vector

[upper sphinx]

@grave forge Sent you image in DM

[earnest atlas]

And how exactly that works to make Fov?

[pine bone]

thats what im asking, the attachments are inside the model.

public void ConnectTo(Attachment attachment)
{
    occupier = attachment;
    attachment.occupier = this;

    baseObject.transform.rotation = Quaternion.Inverse( transform.rotation * attachment.transform.rotation);
    Vector3 offset = attachment.transform.position - transform.position;

    baseObject.transform.position += offset;


}```

This is my current script, it didnt originally change the rotation but since i'm adding the ability to switch between attachments while building i needed it.

Look at the image, think as if the boxes are the main objects and the arrows are the attachments facing out. How can i always make sure the attachments are at the same position and facing each other (While changing the parent position too)

[shell sorrel]

that code will do amost nothing

[polar acorn]

That would log the value of your unused, unnecessary value

[shell sorrel]

will rotation by a fraction of speed once and only once

[mild osprey]

Well I was just told to debug and check so I can see why my propeller still isn't spinning

[swift crag]

ah, I know exactly how to do this one

here's what you want to do:

[rich adder]

because maths

[shell sorrel]

you need the rotation code in Update

[polar acorn]

It's spinning exactly as you've told it. A smidge less than one degree of rotation when the object is first created. Check the rotation before playing and after, and you'll see it's very slightly different

[mild osprey]

ah, duh

[rich adder]

https://youtu.be/xlnkTEyAx7Q

[toxic frigate]

spent today's session setting up SOs for my gameobjects' stats and configs, truly a rabbit hole ngl
the urge to turn every static value into a SO
tomorrow imma move forward with the buffs system using SOs hopefully wont be as taxing as today

[earnest atlas]

I don't really understand what dot does on non normalized vectors. It returns the angle?

[rich adder]

watch video I sent

it explains

[polar acorn]

It returns the "sameness" of two vectors. 1 If they're facing the same direction. -1 if they're opposite

[timid hinge]

Hi, does anyone know how to place the dungeons with the straight walls forming a square

[lusty girder]

@swift crag I guess what I'm trying to ask is, what could be a way to change the code under //Rotation to work with AddRelativeForce? i don't really get how to change //rotation code to be compatible with it

[earnest atlas]

Arent that normalized vectors dot?

[pine bone]

yes

[earnest atlas]

I will, im just kinda not home

[nimble hinge]

If you're using physics engine

[swift crag]

https://gdl.space/qehuxazawe.php

had to rename everything

[polar acorn]

It's every vector

[swift crag]

The rough idea is that you calculate the offset between the parent and the child objects.

[earnest atlas]

Oh I think I understand

[swift crag]

root goes where our parent is, and handle goes where we are.

[earnest atlas]

No i dont 😦

[rich adder]

no worries , if you need an example ill be home around later

[swift crag]

Then we move handle to where we want the child to end up

root is parented to handle, so it moves as well

Then we move the parent to where root is

Since root and handle still have the same offset they began with, the child now winds up exactly at handle

here, let me show you the context I used this in

https://gdl.space/quconozexa.cs

I used this to attach a ragdoll to a joint.

[verbal dome]

Do you want it to only rotate on the Y axis (left to right)?

[swift crag]

I have to teleport the root of the ragdoll such that the Rigidbody I care about winds up exactly at the Joint's position and rotation.

[earnest atlas]

Oh funy enough I understood it

[lusty girder]

Yes, correct

[pine bone]

can you explain to me what should i set the variables to? i have attachment 1 and 2

[swift crag]

I presume you're trying to make attachment 1 move to where 2 is.

[nimble hinge]

transform.up?

Or you could use Rigidbody.Rotation

[pine bone]

yes

[swift crag]

attachment 2 is the destination. attachment 1 is the child, and whatever attachment 1 is parented to is the parent

(the parent can be a grandparent, too, or anything further out)

[earnest atlas]

(vector-vector2).Normalize
Same as result of the opearation.Normalize?

[verbal dome]

So basically you want your transform.forward to rotate towards moveDirection.
I would use cs Vector3.SignedAngle(transform.forward, moveDirection, Vector3.up)
To get the angle from current forward to the desired forward direction, along Y axis (Vector3.up here)
Then I would use AddTorque(0, thatAngle, 0)

[grave forge]

guys why dont i have 1st person templates in unity hub

[earnest atlas]

Unity assets its called I believe

[swift crag]

If you're looking for the "microgame" templates, those are only available for the 2021 LTS

[grave forge]

ok ill install the other version

[lusty girder]

Thank you, I'll try that!

[swift crag]

I might create a version of this that's a coroutine, so that you can visualize each step

[verbal dome]

Try to understand it too. This is useful stuff

[swift crag]

but later; i need to get to work :p

[pine bone]

do i need to keep the handle and root

[nimble hinge]

this is the difference using normalize and not using it

[lusty girder]

it is also surprisingly complex for starting out haha. But it is fun to learn. Anyway, thanks again.

[nimble hinge]

right one shows normalize, you're trying to achieve

[verbal dome]

Yeah physics takes some math. But you don't have to really do trigonometry, just learn what the Vector3/Quaternion functions do

[nimble hinge]

And first one is around 1.4, because of pythagoras theorem

[nimble hinge]

eh atan2 is needed ill say

for converting mouse position in world space

[rich adder]

not necessarily

[swift crag]

no, which is why my code destroys them at the end

[swift crag]

I do very little trig!

[nimble hinge]

But it depends too

[swift crag]

Vector3 and Quaternion are really handy

[nimble hinge]

It's not that needed

[devout flume]

Can I use a monoscript like a standard class? By that I mean:

namespace test {
  public class Test {
    //Fields

    public Test() {

    }

    public Test(...) {

    }

    public ... get() {
      return ...;
    }

    ...
  }
}
```?

[shell sorrel]

well being good at trig does help often though

[swift crag]

Do you mean a MonoBehaviour?

Or do you just mean a script file that defines a plain old C# class?

This looks like the latter.

[languid spire]

no

[devout flume]

If a MonoBehavior is a script attached to a game object, no
Just plain script

[swift crag]

Test is not "a monoscript". It is true that it's defined in a file that unity imports as a MonoScript asset, but that has no bearing on what Test is

Test is a class.

and since it doesn't derive from UnityEngine.Object, Unity doesn't really care about what you do with it at all

so yeah, you can do whatever you want with it

[devout flume]

So I can't define my classes and use them in other stuff?

[swift crag]

Of course.

[devout flume]

Oh, so I can

[nimble hinge]

The namespace you defined, can be used

[languid spire]

yes, as long as the do not inherit from Monobehaviour

[devout flume]

Yes, I kinda see the transition between java and C#

[swift crag]

Unity starts getting upset if you try to construct something like a MonoBehaviour or ScriptableObject.

[devout flume]

I was quite surprised on the similarities C# have with java

[earnest atlas]

My brain just goes nope when anything is related to vectors. Literally just goes nope

[verbal dome]

True, but I got pretty far while being kinda terrible at it. I do need some refreshers lol

[swift crag]

well, you'd better stop bailing out the moment you see a tiny bit of math

[nimble hinge]

Vectors are fun

[swift crag]

I despise the "i'm just dumb and i'll never understand math" mindset

Stop putting yourself down

[nimble hinge]

you know coordinate system right?

[pine bone]

whats the targetroot?

[verbal dome]

What helps me is visualizing it. Debug.DrawRay/DrawLine, for example. Visualize all vectors you are working with and it will start making sense

[shell sorrel]

work with it long enough it becomes intutative

[earnest atlas]

I went math heavy route at school

I just dont understand them

[swift crag]

puppet.targetRoot? That's the root transform of the ragdoll.

Look at the first script. I made the names generic there.

The second script is there to show you a place where I used that logic.

[pine bone]

it still has targetroot

[swift crag]

oh! my bad

[verbal dome]

The usual usecase for that can just be replaced with transform.up = (mouseWorldPos - transform.position)

[nimble hinge]

Yes, Also a very good alternative!

but just in case, you can use that too

[verbal dome]

True

[swift crag]

https://gdl.space/zenadoleza.php

Here, I got rid of all of those redundant transform properties

Transform what = ...
what.transform.position = Vector3.zero;

I do this way too often.

transform.transform.transform.transform.transform.transform.transform.transform.transform.transform.position = ...

[verbal dome]

transform does have some overhead

So if I have a method where I would call transform 10 times I just cache it (especially in Update/FixedUpdate)

And yeah readability

[pine bone]

thanks

let me try

[pine bone]

my attachments are rotated 180 degrees (facing inside) so should i just use quaternion inverse for the rotation?

[mild osprey]

Thanks ya'll that definitely helped and now I also know a few extra things for the future

[swift crag]

You'd need to correct for that. Quaternion.Inverse wouldn't be appropriate though

If it's 2D you can probably just multiply by Quaternion.AngleAxis(180, Vector3.forward)

[pine bone]

Does this script make the attachments face each other or the same direction?

[swift crag]

It copies the rotation of the destination transform.

[pine bone]

i reversed the rotation and it worked thanks

oh wait it didnt

[gray pond]

would somebody mind helping me out quick? got this error after following a tutorial to make a dash

what would this error mean?

i can link the code on a pastebin

[slender nymph]

https://unity.huh.how/runtime-exceptions/nullreferenceexception

[summer stump]

It means the thing you're trying to reference does not exist, it is an "empty" variable

[gray pond]

oh what the fuck

ok that's a start

[pine bone]

When i multiplied the rotation by 180 degrees, the script thinks that these locations are occupied

[gray pond]

ty i'll look at this

[swift crag]

great avatar-message combo here

[rich adder]

it will tell you exactly which line
always open /look the error expanded in Console window

[meager steeple]

instead of setting fullscreen to true when im changing resolution, i want it to stay the same as what it was, what do i change "true" to be?

[gray pond]

oh it says line 49 ok ok

[slender nymph]

you need to get your !IDE configured. there is a concerning lack of syntax highlighting here

[eternal falcon]

💡 IDE Configuration

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

Select one:

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

[rich adder]

sure hope that thing is configured btw, weird colors

[polar acorn]

Then something on line 49 is null but you're trying to use it anyway

[rich adder]

maybe its VS2017 theme 😛

[slender nymph]

pretty sure types would still have syntax highlighting with that

[meager steeple]

there are but it just doesnt show in the ss i dont know why

[gray pond]

i'm gonna ctrl and f each piece of it to see what's up

[meager steeple]

maybe it didnt load

[slender nymph]

screenshot your entire IDE to show that it is configured

[rich adder]

also - references is concerning

def not configured then

[meager steeple]

if you teach me how

[rich adder]

#💻┃code-beginner message

[slender nymph]

how to what? screenshot? you already know how

[gray pond]

would these be the same thing or do i need to make a variable called _rigidbody.velocity

[shell sorrel]

#💻┃code-beginner message

[meager steeple]

right it was set to 2019

once i set it thats all i have to do?

[polar acorn]

Where do you asign a value to _rigidbody

[slender nymph]

#💻┃code-beginner message

[rocky canyon]

_rigidbody is the name u gave ur Rigidbody2D

[short hazel]

The fact that both color up when you select one shows it's referring to the same variable. It might not have avalue though

[meager steeple]

i read it..

3 people pinging the same thing but no one gonna say anything else

[slender nymph]

then surely you know that there is more than just a single step

[rocky canyon]

whenever u reference it (_rigidbody) ur actually referecing the RIgidbdoy2d

[gray pond]

oh so it might be the value??

i need to make a value

[short hazel]

You need to put a value in the variable yes

Otherwise it's at null by default

[gray pond]

ahh silly me

ty bros

[summer stump]

What do they have to say? It is step by step instructions

[meager steeple]

yh theres 2 and ive done those 2

[summer stump]

Nope, more than 2, that you have to verify at least

[slender nymph]

prove it

[meager steeple]

✨ syntaxes

[slender nymph]

there you go. wasn't reading and following the directions so easy?

[meager steeple]

so will you help me now or not

[gray pond]

ah sorry i can't figure out how to add the variable for my rigidbody.velocity

[slender nymph]

anyway, to answer your question just get the current state of the fullScreen property
https://docs.unity3d.com/ScriptReference/Screen-fullScreen.html
and RTFM

[short hazel]

Are you doing _rigidbody = something anywhere? That puts a value into it

[rich adder]

the .velocity is a Vector2

[meager steeple]

so i replace "true" with "Screen.fullScreen"

[rich adder]

what do you think

[ivory bobcat]

It means your variable isn't referencing anything - it's reference nothing (null)

[meager steeple]

i think yes but i wanted to make sure since i have to build and run the game every time to test it so it takes me a while

[rich adder]

You could just build like an empty scene if you want to just test full/window

[meager steeple]

that would take me even longer

[rich adder]

sure exporting an empty scene with a few scripts longer alr

[spiral narwhal]

How do I "update" OnPointerEnter?

In my game, if I'm hovering over a card, it shows a detailed view explaining what the card does. It only does so, however, if no card is currently selected.
Therefore, in OnPointerEnter, I return out of the method if that bool is true. If I click right click, the selection stops, which works great, but here's the issue:
If the user hovers over a card whilst the lock is active, then right-clicks to remove the lock, the card is not considered "hovered" because right now, I'm not alerting Unity that it should re-evaluate OnPointerEnter. Hope that made sense

[rocky canyon]

u need to keep up with the cards u have currently selected

[swift crag]

so would spending all of your time complaining about it here instead of Just Doing It

[rocky canyon]

then u can change the functionallity of what clicks/ hovers do depending on if that card is selected atm

[dire tartan]

if ive got an animation and its set with a bool and once that bool is true i want the animation to finish even if the bool is set to false during the animation what setting is it to do that

[rich adder]

Has Exit Time

[meager steeple]

i dont see anywhere where i was complaining

[dire tartan]

thank you

[spiral narwhal]

No, that's not what I mean. I want OnPointerEnter to be called again, even though the mouse has not left and re-entered the GameObject

[rocky canyon]

oh, unsure about that oen

[spiral narwhal]

Ok

[rich adder]

why ?

there are other events

but idk what the usecase is exactly

[spiral narwhal]

This is the use case

[short hazel]

OnPointerEnter, set bool to true. OnPointerExit, to false. In Update check that bool and run code each frame if it's true

[spiral narwhal]

But Unity does not update OnPointerExit and Enter if I don't leave the GameObject with the mouse

I will post a Gif if that's allowed

[slender nymph]

#💻┃code-beginner message

[spiral narwhal]

Well yes I was referring to that

[swift crag]

okay, so do your work somewhere else

like, say, Update

OnPointerEnter tells you when the pointer enters the object. That's it.

It would be useless if it ran at any other time.

[slender nymph]

and you could even do something like flip a bool in OnPointEnter/Exit to tell Update when it needs to do the work

[spiral narwhal]

So here you can see that when I right click to remove the "lock" OnPointerEnter is not called because I have not left and re-entered the object

[gray pond]

ah ok, i've figured out why i couldn't dash but now i can't move my player character, and when i want to dash it only goes up if i press up on my keyboard and dash

[swift crag]

yes, which is why you shouldn't use OnPointerEnter to move the card

you should just use it to set a boolean to true

somewhere else, you can use that boolean to decide what to do

[spiral narwhal]

Oh I think I understand. So the objects always no whether or not they are being hovered over?

No matter the lock

know*#

[gray pond]

https://pastebin.com/XknAAgRH can somebody help me with this?

i typed the issue at the start

[slender nymph]

what is this "lock" you are referring to?

[spiral narwhal]

So if I click on a card it is considered "locked", so other cards cannot be hovered over if one has been clicked

[slender nymph]

and that sounds like an issue with your logic rather than how the event system interfaces work

[spiral narwhal]

Hm I suppose

[swift crag]

use OnPointerEnter and OnPointerExit to do nothing other than set a boolean on the card

decide how to position the card based on that boolean and whatever else you care about

[rocky canyon]

sounds like u have some jumbled if conditionals/ input gathering..

[slender nymph]

where do you use your inputX variable? or assign to horizontal

[trim gulch]

Hello. Is it possible to make a Rigidbody ignore collisions with another one based on a tag or something like that? I have a 2D game where the enemies shoot, the bullets have their own rigidbodies, but I don't want them to collide with other enemies

[spiral narwhal]

Ok! :)
One last question: Won't that clog Update, though?

[rocky canyon]

like maybe the jump is nested in an if else statement that has to be moving first b4 it gathers the jump.. not sure

[swift crag]

your computer is very fast

it will survive running Update 60 times per second on 15 cards

[rich adder]

Layers or Colliders
https://docs.unity3d.com/Manual/LayerBasedCollision.html

[rocky canyon]

peep this panel

you'll be able to disable any interactions between layers u wish

[ivory bobcat]

Ignore Layer https://docs.unity3d.com/ScriptReference/Physics.IgnoreLayerCollision.html
Ignore Collider https://docs.unity3d.com/ScriptReference/Physics.IgnoreCollision.html

[trim gulch]

I guess that was too much of a begginer question, thank you all!

[rocky canyon]

nah, not at all

[gray pond]

ahh yeah you might be right

[rocky canyon]

it sounds that way

most jumps work independently outside the move functions.. when u jump u add a y value to ur overall vector

then when the move function runs, it just has the jump tacked in with it.. but theres other ways too

did u share ur code?

[gray pond]

yeah i did

there's a pastebin above

[rocky canyon]

let me lookie

[gray pond]

tyty

[rocky canyon]

ya, looks like ur only giving the rigidbody values if ur _isDashing

[gray pond]

ah fuck

[rocky canyon]

i dont see any velocity when ur not dashing for example

[gray pond]

ok i see, not sure how to fix that :(

ok let me try

[rocky canyon]

if(isDashing) {velocity = value with ur dash}else{ velocity = value w/o ur dash}

something like that

[gray pond]

should i use that to replace something else or just a new line

well

two lines

[rocky canyon]

just an example.. u shouldnt replace anything w/ it

thats how errors happen.. and people not understanding their own code

[ivory bobcat]

i can't move my player character
You only allow the character to move when dashing or jumping.

Well, I guess you sort of are moving in FixedUpdate

Relative to some horizontal variable that is.

[rocky canyon]

       if (Input.GetKey(dashKey))
        {
            movementVector = input * dashForceMultiplier;
        }
        else
        {
            movementVector = input * normalForce;
        }```
then w/e you move ur rigidbody you have w/e value you need
```cs
        playerRigidbody.velocity = movementVector;

[ivory bobcat]

That isn't at all used in Update or anywhere that I'm aware of.

[rocky canyon]

this is what im meaning.. change ur values around as u need to.. then w/e u move ur rigidbody you'll have already set which values to use.. whether that be movement w/ a dash or movement w/o a dash

[north scroll]

whats usually the best/better method of implementing a simple movement mechanic for a 2d side scroller? Transform.position, rb.velocity, or addforce ?

and are there any others?

[meager steeple]

uh i never had this problem before when trying to close

[rich adder]

rb.velocity

[slender nymph]

if you move using physics with a rigidbody (by either assigning velocity or adding force) then you won't have to manually check for collisions. if you move using transform.position then you are effectively teleporting the object and you must check for collisions manually otherwise you will run into issues where your collider will penetrate into other objects

[north scroll]

ty, what would the use case for the others be tho ?

[rich adder]

transform.position if you dont want collisions to work right
AddForce is good to but at times it feels too unpredictable , depends what ur going for ofc

[north scroll]

appreciate the explaination :D

[meager steeple]

now going for 4 minutes

[north scroll]

i see, i think I know what u mean. When trying to use addforce, if I keep holding down the button, the addforce just keeps adding so... ty guys

[slender nymph]

this isn't a code issue and you really just need to be patient. you can force close it if you want, but it's usually best to just let it do its thing

[scarlet skiff]

why does one a sprite show up in the middle for one frame? it insta killed me when testing lol

laser code: https://gdl.space/zuvaxinuhi.cpp
laser shooter code: https://gdl.space/italoxorag.cs

[sharp wyvern]

I'd do a force shutdown, delete library folder, and reopen to let it rebuild.

[scarlet skiff]

i have cheched the animation and it doesnt have a set position in it

[slender nymph]

you set the position when you spawn it to (0,x) and you do not assign to x so it's just being set to 0,0 until the next frame when that object's Update method runs

also why do you have a variable called x that is being used for the Y position of an object?

[scarlet skiff]

i just wanted it to be public in the inspector so i could test what a good value would be, i removed it now

but when u mentioned x, thats for the laser shooter script, not the laser itself

its the laser that spawns at 0, 0 first

its supposed to spawn on the x value of the laser shooter

unless maybe it didnt count it as a local position

something like this i imagine?

[faint sluice]

Conveniently you have hidden the very thing that shows which position laser is being spawned at

[swift crag]

stop showing us tiny snippets of code

it makes it ridiculously hard to understand what's going on

share entire methods in

code blocks

or entire scripts in a paste site

[faint sluice]

He's explained it perfectly why it spawned on middle for first frame and then moved to desired location

[ivory bobcat]

I think it was shared prior but not certain if any changes have been made#💻┃code-beginner message

[swift crag]

Fair enough.

[faint sluice]

@swift crag not to be that guy but he's already shared code haha
#💻┃code-beginner message

[swift crag]

My mistake.

[faint sluice]

All good

[dusk minnow]

Image prefabImage = prefab.GetComponentInChildren<Image>(); i have an image attached to the object and to a child, i need the image from the child, how i do that

[swift crag]

I'm used to being shown tiny chunks of code that hide the actual problem 😅

[faint sluice]

Same

[languid spire]

Image[] prefabImage = prefab.GetComponentsInChildren<Image>();
you'll want index 1

[faint sluice]

Prefab.transform.getchild(index).getcomponent<image>();

??

[dusk minnow]

ill try that

[faint sluice]

Could be another child, we don't know how many more images he's stored but ye that's better I guess..as long as we know which index image is at

[ivory bobcat]

The spawn position would be the position of the laser object itself.

Scripts do not have positions.

[scarlet skiff]

yea thanks guys, i fixed it now

[faint sluice]

@dusk minnow this is better ^

[dusk minnow]

alr then that 🙂

[swift crag]

why not just directly reference the image you need in the inspector?

[languid spire]

even better

[dusk minnow]

cant explain but i need the one from above

[faint sluice]

I assumed it was instantiated prefab, so hard to get it

Can't pre reference it

[swift crag]

if you can't explain, then how can you be in a position to implement something?

[languid spire]

put a script on prefab that holds a reference to the correct Image. prefab.GetComponent<ThatScript>().image

[swift crag]

or reference the prefab by that component's type, rather than GameObject

now you've got absolutely zero instances of GetComponent

for example, here's a pretty tiny example

public class InputActionIconPart : MonoBehaviour
{
    public TMP_Text label;
    public Image image;
}

(this class now has a bunch of actual logic, but I've removed that to match how it used to work)

all of the members are now private and you interact with it through methods

it's no longer just a "bag of data"

[mild osprey]

I forget if anyone answered me earlier about if there are other more efficient ways to learn coding and all the fundamentals and stuff besides just Unity Learn?

[summer stump]

https://www.w3schools.com/cs/index.php

And the pins here

[languid spire]

learning programming does not work like that, 99.9% will depend your ability and the effort you put into it

[rocky canyon]

go see Elon Musk, might be able to get in the Nueralink beta.. and get the programming knowledge downloaded str8 to ur brain

[gray pond]

hi peeps, just followed a tutorial to implement player movement 2d and a dash, but it only does horizontal dashes
how do i implement dashes for all directions? https://pastebin.com/q3Anx4TS

[mild osprey]

Well I know I can understand the stuff once I learn more of it. And I pretty much have been staying up late since setting up my computer so I am very determined to learn all their is to. I plan to try and make a really good game at least in the next 3-5 years or sooner if I really apply myself

[languid spire]

knowledge is not even close to being enough, analyic ability, logical thought and pattern matching are things that are very difficult to learn

[rocky canyon]

just like u did the horizontal dash.

instead of multiplying just the horizontal values with teh dash u multiply all the values by the dash

[mild osprey]

Well then I would like to get better at all of that too. I'm definitely smarter than my fi4rst impression gave off lol.

[gray pond]

yeah see, i tried writing an else if statement like "rb.velocity = new Vector2(vertical * speed, rb.velocity.x)" but i'm not sure why they didn't work 😭

[gray pond]

what's the keyword for all values

[rocky canyon]

it just comes down to practice and repetition

[gray pond]

instead of horizontal

[rocky canyon]

"Horizontal" and "Vertical" are the two common inputs

WASD

[mild osprey]

Well I've got plenty of time for practice. And I will repeat things as often as possible.

[rocky canyon]

do u know what that line of code is doing?

Vector2(x,y)

ur multiplying the vertical input with speed for the first value (x)

and then for the y value it seems ur just using the rigidbodies x velocity

w/e that may be..

x, y is normally flipped from how u have it 🤔 (horizontalInput * speed, verticalInput * speed);

or it could just be.. cs Vector2 myVector = (horizontalInput, verticalInput); myVector = myVector * speed;

[polar acorn]

That would be setting this object's X velocity to vertical * speed and setting its Y velocity to whatever its X velocity used to be

[rocky canyon]

ya, it seems bass ackwards to me

but it could be just b/c of the way ur world is facing

like portrait vs landscape

[gray pond]

would something like this work?

[rocky canyon]

nope

[gray pond]

oof

[polar acorn]

GetAxisRaw does not take a boolean as a parameter

And you cannot && two strings to get a boolean

[rocky canyon]

myVector = (Input.GetAxisRaw("Horizontal"),Input.GetAxisRaw("Vertical"));

[rich adder]

oh my

[rocky canyon]

&& is a comparison

[gray pond]

omg i'm getting dogged 😭

[polar acorn]

Also wrong, unless myVector is a float tuple

[gray pond]

lol

[rocky canyon]

Vector2

new Vector2()

ahh yea i see

        float horizontalInput = Input.GetAxis("Horizontal");
        float verticalInput = Input.GetAxis("Vertical");
        Vector2 move = new Vector2(horizontalInput,verticalInput);``` is what i meant to say

[rich adder]

the other would've worked too one line if you just had added new Vector2

[rocky canyon]

thats just the basic input... after you grab that u do all the stuff like multiplying with forces and dashes and stuff

[gray pond]

this is rough

[rocky canyon]

lol.

[rich adder]

you wont understand unity's API

if you dont know basic c#

[rocky canyon]

it gets easier the more u do it.. but understanding what it is to begin with helps alot..

debug values, watch console logs, experiment etc

thats how u learn

and ofc reading/ studying

why not both

[gray pond]

like, microsoft first then sebastian

[gray pond]

that's what i said

[rich adder]

doesn't matter which order

[rocky canyon]

do em both at the same time..

watch a video or two of the playlist.. then go over to text stuff and check out / read a little more context about what u just watched, etc

[ashen wind]

I'm trying to make a popup that occurs when the player mouses over something and I'm using OnPointerEnter and OnPointerExit to do it, but if I mouse over the UI object, it flickers on an off like enter and exit are consantly calling. I don't really understand why it's doing this

[summer grove]

does someone have to go through:
private float a
private float b

void start()
{
a = getComponentBoxCollidersize.x/2

void update()
if (blablbalbla... blablblabla. -725 a)
{
blablbalbal. b
}

this. when they can just measure the objects lenght and get the number then divide by 2 for free? (I know both work. I am asking optimization-wise)

[ashen wind]

anyone have any ideas for how to do this so it doesn't flicker?

[rich adder]

what

[summer stump]

Divide by 2 for free?

[rich adder]

what does for free mean in this context , im so confused

[gray pond]

it's kinda annoying tho for me tho, i'm in my second year in college for game dev in the uk and i don't really know how to do anything game dev wise, and my final project is coming up so i'm kinda just grasping at straws 😭

[rich adder]

thats um..school for ya

[summer grove]

You dont have to write "a = getComponentBoxCollidersize.x/2" you can just add a mesh collider and look at its X size then divide by 2 is what I mean. then write that number to update manually

[gray pond]

yeah, i at least know what variables are, i think :3

[rocky canyon]

lol.. instead of sitting and telling us about how ur losing time.. use that time to be reading/ watching those videos

[rich adder]

generally is better if you store the result than GetComponent every frame..

or at least cache the component

GetComponent is pretty expensive in Update

[summer grove]

why

[rocky canyon]

GetComponent every frame is being mean to ur processor

[summer grove]

I have my project ready I am making adjustments

[summer grove]

yeah. That's why I think of removing it

[rich adder]

Hence why I suggested GetComponent in Update is bad

[rocky canyon]

cache it Once.. use the reference u cached the rest of the time..

[rich adder]

yeah its easy, just store the reference

[ashen wind]

anyone know a better way to do this?

[summer grove]

no thanks I am bored. I will do all manually. Good night.

[rich adder]

well depends what ur donig OnEnter ofc

[rich adder]

why the hell would you ask if you dont take our advice then

[rocky canyon]

i honestly dont care, its ur project 🤣

[rich adder]

ur only hurting your on game's perfomance

[summer grove]

To see if there would be any downsides to it.

[rich adder]

we just told you...

[rocky canyon]

well there are.. so keep it going

maybe it'll build w/o flatlining

[summer grove]

How?? I will remove getcomponent ffrom all of them

[ashen wind]

it depends on what? the OnPointerEnter function is on a script that is on a canvas UI element

[rich adder]

because what SpawnCampSuggested is how you fix it instead of entirely removing it

but yeah its your project do whatever

[rich adder]

wdym

what does OnPointerEnter DO in the script.

I know what function is

[ashen wind]

oh. it turns on a gameobject that is the mousover text

and turns it off when you stop mousing over

[rich adder]

then its blocking the raycast

untick RayCast target in TMP component's extras section

[polar acorn]

"Oh no, I accidentally made this mesh too big, I need to adjust it's size slightly."
A normal person: Adjusts the size
You: Spends six weeks changing magic numbers, missing some, encountering bugs, and repeating

[rich adder]

its in an endless cycle, You enable it it blocks raycast and runs OnPointerExit then disables then blocker, Running OnPointerEnter again

rinse and repeat

[rocky canyon]

this is how u'd cache variables...

• in the Awake() for example (Only runs once.. u get the component and set it)
• then when you use it in Update or w/e you're getting the reference you already set.. instead of GetComponent every time..

[summer stump]

Massive downsides

[ashen wind]

thanks. I did that but it's still flickering. could something else be blocking the raycast besides text?

[summer grove]

How could there be downsides to measuring 33 game object's mesh's X value then diving by2 then writing manually 🤣

[polar acorn]

#💻┃code-beginner message

[summer stump]

It has been explained to you over and over

[ashen wind]

there's a panel behind the button, but no other ui element overlaps

[rocky canyon]

use a bigger collider over the text.. and the text attached to it..

[summer stump]

It's terrible

[rocky canyon]

using Text as the collider itself is terrible.. b/c u have to hover exactly over the little bits of the letters

[rich adder]

Could be, the best way to find out what it is. Inspect the Event System during playmode

it will tell you exactly whats being Hit

if anything share script as well

[ashen wind]

omg

the popup is blocking itself i think

i didn't think of that

yep that was totally it

[swift crag]

Yeah, that's a common error.

i only thought it was a preview window

for models and audio clips and whatnot

didnt even think of it displaying data like that

Veryy handy for debugging !
back in the day I had no idea text objects also had Raycast bloking until I found this

[rocky canyon]

i did know that

b/c of the wireframe

[swift crag]

It can also display things like layout properties for RectTransforms.

[halcyon summit]

When I'm updating the colour of a UI material, UI elements inside a Scroll View aren't updating. Does anyone know how to force a Scroll View to refresh and adopt the changed colour?

[swift crag]

Very useful for understanding why your UI is doing whatever it's doing

[rocky canyon]

yea, game changer!

[swift crag]

the scroll view has nothing to do with the color of the graphics that happen to be parented to it

it just moves a RectTransform around

those graphics must have different materials

[halcyon summit]

They have the same material attached

[rich adder]

must be somewhere else then where you're not setting them properly

[swift crag]

perhaps you're instantiating the materials somewhere

[halcyon summit]

Every UI element adopts the new colour except the elements inside the Scroll View. The actual material itself is being changed

[swift crag]

hang on..."Scroll View"?

Is this UIToolkit?

[rich adder]

are those objects instantiated ?

[swift crag]

I was thinking of UGUI

[rich adder]

oh I thought also they meant ScrollRect

[swift crag]

ScrollRect is the UGUI component.

[rich adder]

this changes things then certainly, Uitoolkit is tricky with binding changes

[swift crag]

I haven't learned UIToolkit yet myself, so I can't say too much

[halcyon summit]

It's the element generated when choosing UI > Scroll View in the Hierarchy window

[swift crag]

Okay, so this is UGUI.

[rich adder]

oh then its the ScrollRect

[swift crag]

Do the colors change when you modify the material outside of Play Mode?

[halcyon summit]

Yeah

[rich adder]

How are you filling that Container ?

[halcyon summit]

Image

[rich adder]

are they instantiated

[swift crag]

i'm not sure how you'd put objects in a scroll view that aren't instances

[halcyon summit]

No, these particular ones are just individual objects existing on the canvas

[swift crag]

oh, I see what you mean

[rich adder]

before gamemode you drag them inside ig

[swift crag]

instantiated from a prefab, right.

continue

[halcyon summit]

Do you think using prefabs for them would help?

[rich adder]

oh na I thought thats why it was different maybe

but nvm

[rich adder]

can you maybe make short vid of what's going on with others n stuff ?

[halcyon summit]

Sure

The top boxes are in the scroll view, I placed that single one below outside of the scroll view just to show that it works outside of it

[swift crag]

I wonder if your images are getting crushed down to 0x0 size

which could happen depending on how your layout group is set up and how the individual elements are structured

hm, but I'd expect that to happen outside of play mode, too

(and you'd need to have another image in each element, or else the element would just be completely invisible here)

[halcyon summit]

Does it make a difference that these objects are inside horizontal layout groups that have content size fitters?

[swift crag]

Do they have a parent that also has a layout group?

You will see a warning in the ContentSizeFitter if so

[halcyon summit]

Yeah they're in horizontal layout groups for the rows, and all rows are nested inside a vertical layout group

[swift crag]

Okay, that's not correct.

This is going to screw up the layout calculations, since each horizontal object is going to be trying to set its own size

You should have one content size fitter, and it should be on the "Content" object

The gist of auto layout is that each layout group asks its children for how much space it needs, then asks for enough space to contain them

If you don't have layout groups all the way down, an object will ask for zero width and zero height

ContentSizeFitter is used when you don't have a layout group in your parent

like on the Content object in a default scroll view

[rich adder]

btw also could you show how do you change the color in code?

[swift crag]

I'm guessing that each item here has a "background" image and a "foreground" image, and then the foreground image is getting shrunken out of existence

i'll need to see the hierarchy to say anything more concrete

[swift crag]

• Content <- ContentSizeFitter, VerticalLayoutGroup
  • Row <- HorizontalLayoutGroup
    • Item <- VerticalLayoutGroup
      • Foreground
    • Item <- VerticalLayoutGroup
      • Foreground

an example

[swift crag]

ah yep, that's it

what is "Empty space" for on the "Classic Skin 1" object?

[rich adder]

had to double check, but yea scroll rect has no effect

[halcyon summit]

You can see it here. It's just a rectangle with the background colour. I just made it as an easy way to make the green border

[swift crag]

i thought that was what "BG" would be for

[devout flume]

Can we change splash screen images without a pro+ plan?

[rich adder]

not until unity 6

[halcyon summit]

material.color = newColour;

newColour being a hex

[devout flume]

So I should be able to. I have the latest LTS 2022 version so

[rich adder]

Unity 6 isnt even out yet

[devout flume]

Oh

Damn

[rich adder]

oh you're not changing the color on the image compoent ?

[halcyon summit]

No, changing the material itself so that every object with that material will update

[swift crag]

Anyway, you need to add a LayoutElement to "Classic Skin 1". Turn on Minimum Height to enforce the height. Turn on Flexible Width so that it'll grow to fill the horizontal space.

"Classic Skin 1" should not have a layout group on it. All of its children should also not have layout groups or layout elements on them.

Set all of those children to stretch in both axes, then adjust the left/right/top/bottom properties to create margins as needed (e.g. the "Swatch" should be pulled back on all four sides a little)

Next, make sure that "Row 1" has a HorizontalLayoutGroup. It should be set to control child size in both directions. Turn off "force expand" in both directions.

Next, make sure that "Content" has a VerticalLayoutGroup and a ContentSizeFitter. Configure the layout group as above, and then make sure the content size fitter uses the minium size vertically.

I believe that your current setup is causing the swatch image to shrink down to 0x0 in size

[dire tartan]

if i wanted to make a physcis lever would i use a configarble joint and lock the other axis?

[rich adder]

depends..

what kind of lever, hinge also works

[swift crag]

The LayoutElement will control the size of each box. The layout groups will arrange them properly.

[dire tartan]

i want it to be able to go up and down

[rich adder]

oh ok , maybe try doing it how I do it and loop through images u want to change.. My guess its creating a copy of the material maybe or probably what Fen is saying

[dire tartan]

and the character can move it by grabbing the end and pulling it up or down

[rich adder]

a hinge should work just fine IMO

[swift crag]

you can check if I'm correct by checking the scene view whilst the game is running. Select the various parts of each skin button and see how large they are.

[dire tartan]

okay i will try that

[rich adder]

configurable joint is prob one of the hardest ones to tinker with

[swift crag]

Sounds like a hinge joint to me.

It swings around a single axis

[rich adder]

yeah def a hinge

[halcyon summit]

Thanks for going in to so much detail for me. Those changes appear to have made the height 0

[swift crag]

Control child size on both axes.

you will want to do that on every layout group

[halcyon summit]

Ah yeah, missed that, thanks. Now Content is 0 altogether. Is that to do with the min height of my Elements, which are currently 0?

[swift crag]

Show me the inspector for Row 1

[swift crag]

and now for Classic Skin 1

[swift crag]

You need a non-zero Min Height

set that to whatever you want the element's vertical size to be

[night sparrow]

Can someone help with this code, It gives me error Not sure why as the thing i need IS assigned in the inspector script!

public class Health : MonoBehaviour
{
    public int health;
    public bool isLocalPlayer;

    public RectTransform healthBar;
    public TextMeshProUGUI healthText;
    private float originalHealhBarSize;

    private void Start()
    {
        originalHealhBarSize = healthBar.sizeDelta.x; // Error for the healthBar.
        healthText.text = health.ToString();
    }

    [PunRPC]
    public void TakeDamage(int _damage)
    {
        health -= _damage;

        healthBar.sizeDelta = new Vector2(originalHealhBarSize * health / 100f, healthBar.sizeDelta.y);
        healthText.text = health.ToString();

        if (health <= 0)
        {

            if (isLocalPlayer)
                Debug.Log("Respawn");

            Destroy(gameObject);
        }
    }
}```

```c#

[swift crag]

(also, this is a #📲┃ui-ux problem, so we should go there if the problem isn't solved yet)

[halcyon summit]

Thanks Fen, the layout looks right now. However the problem of the colours not updating remains

Aha alright, thanks

[rich adder]

if its assigned, check there are copies of this script on other objects
search t:Health inside hierarchy

[rich adder]

is this the correct scene

[night sparrow]

yes

[rich adder]

show me how you assigned it then

[night sparrow]

Okay so

Player has the script, I selected the "Health" bar the one thats a child of Health BG dragged it into the script into the little box where u can put it and now it looks like

[rich adder]

check it during playmode the one spawned, if its empty something else is changing it

[polar acorn]

Run it after the game starts, when your error is in the console

[dire tartan]

what have i setup wrong?

[rich adder]

why did you not use hinge like suggested ?

what is even the point of asking others if you dont take their responses

[dire tartan]

i think i added the hinge whilst in game mode and it undid it my bad

[night sparrow]

I aint sure whats wrong its there and no error now didnt change anything im so confused though

Thanks though

[full imp]

Hey, I'm trying to implement an inventory system with PUN but I keep on getting this error when picking up an item.

This is the part of the script where it calls the add item method

IInventoryItem item = collision.collider.GetComponent<IInventoryItem>();
        if (item != null)
        {
            Debug.Log(item.Name);
            Debug.Log("collect item");
            inventory.AddItem(item);
        }```

and this is the inventory class

```c#
public class Inventory : MonoBehaviour
{
    private const int SLOTS = 10;

    private List<IInventoryItem> mItems = new List<IInventoryItem>();

    public event EventHandler<InventoryEventArgs> ItemAdded;

    public void AddItem(IInventoryItem item)
    {
        if (mItems.Count < SLOTS)
        {
            Debug.Log("Hit Item");
            Collider collider = (item as MonoBehaviour).GetComponent<Collider>();
            if (collider.enabled)
            {
                collider.enabled = false;
                mItems.Add(item);
                item.OnPickUp();

                if (ItemAdded != null)
                {
                    Debug.Log("Add item");
                    ItemAdded(this, new InventoryEventArgs(item));
                }
            }
        }
    }
}

If there's anything obvious I've done wrong please let me know, thanks 🙂

[north kiln]

Use TryGetComponent instead of GetComponent and checking for null

https://unity.huh.how/unity-null#using-interfaces-or-object

[polar acorn]

Which line is line 100

[full imp]

inventory.AddItem(item);

[polar acorn]

inventory is null

[shell sorrel]

casting to a MB to use GetComponent is really weird

[full imp]

will check that, thanks 👍

[shell sorrel]

like would have methods on the interface to do the checks you need, or simple have GetComponent be part of the interface

[full imp]

What's MB?

[shell sorrel]

MonoBehaviour

[full imp]

ah

[spiral narwhal]

        protected bool isOnPointer;

        public void OnPointerEnter(PointerEventData eventData)
        {
            isOnPointer = true;
        }

        public void OnPointerExit(PointerEventData eventData)
        {
            isOnPointer = false;
        }

        private void Update()
        {
            HandleHighlight();
        }

        private void HandleHighlight()
        {
            if (isOnPointer) HighlightSelf();
            else UnhighlightSelf();
        }

Because of the way the objects are layered, when the mouse moves from left to right, OnPointerEnter is called before OnPointerExit, and when the mouse moves from the rightmost card to the leftmose, the other way around. However, I would need either to be called in both cases. Any idea how?

[rare basin]

You know that there are events for UI element being Selected or Deselected

You dont need to make this system from 0

https://docs.unity3d.com/2017.3/Documentation/ScriptReference/UI.Selectable.OnSelect.html

[spiral narwhal]

What does "Selected" even mean in this context

[rare basin]

If it's a UI, of course

[shell sorrel]

the selected in this context is mostly for stuff like gamepad/keys navigation

[rare basin]

Nope

Also for mouse

When you hover over UI selectable like button

[spiral narwhal]

Ok ok but that does not answer my question

[rare basin]

It is also selected

[polar acorn]

Make a manager class that has a variable for the currently hovered card. Have that object use raycasts to detect which card is currently hovered. Whenever that value is different from what it used to be, send a message to the old card telling it to unhighlight itself, then change the selected card, then tell the new card to highlight itself

[full imp]

IInventoryItem item = collision.collider.GetComponent<IInventoryItem>();
        if (TryGetComponent<IInventoryItem>(out item))
        {
            Debug.Log(item.Name);
            Debug.Log("collect item");
            inventory.AddItem(item);
        }```
So I managed to turn it into this using the TryGetComponent but nothing's happened - that means that item is null?

[polar acorn]

#💻┃code-beginner message

[full imp]

oh right

[shell sorrel]

also this code is far from correct

nuke the first line of it and make it
if (collision.collider.TryGetComponent<IInventoryItem>(out var item))

[full imp]

Oh thanks that's made it better

I'll have to look for a way to make inventory not null as that seems to be the main problem

[thorn kiln]

So I got kind of an esoteric question. I play a lot of games where, if they're not in fullscreen, they have the maximize button greyed out. This irks me to no end. Is it super hard to impliment or something?

[shell sorrel]

heavily depends on the game engine and how UI works

often its done that way so the aspect ratio can be enforced

[thorn kiln]

Well the one Im looking at right now is unity

[shell sorrel]

its prolly so they can enforce the window be like 16:9 or something

that way you can like maximize it on a ultra wide

or because they want to use very exact resoultions

[open apex]

So I have a quick question for the pros, I am trying to code player movement. I 1st learn to make a player move by adding force to it and now I have discovered "CharacterController". Does it really matter or is it really important how you code the player movement? I feel like a b**ch for using something like this instead of hard coding the movement by myself.

[rocky canyon]

u still code the movement.. the character controller is just the component u tell to move. the only thing it does is has built in ground checks and the ability to collide and traverse stairs

[frosty hound]

If it turns out how you want it, it doesn't matter how you made it.

[rocky canyon]

https://medium.com/ironequal/unity-character-controller-vs-rigidbody-a1e243591483

its really more of what component fits my needs better

[gritty notch]

does anyone know why this happens? this animation triggers when i click and it kind of glitches when i click but works fine when i hold the mouse button down. also the errors are unrelated

[vast vessel]

hey guys.
im getting an error saying i haven't given the match argument even though i have. what's the issue?

List<Assault_RallyPoint> validRallyPoints = rallyPoints.FindAll(CanUseRallyPoint);
public static bool CanUseRallyPoint(Assault_RallyPoint rallyPoint) => rallyPoint.shouldLockRallyPoint ? !rallyPoint.occupied : true;

[polar acorn]

What is the actual error

[wintry quarry]

You should keep this window open

[vast vessel]

Error CS7036 There is no argument given that corresponds to the required parameter 'match' of 'Array.FindAll<T>(T[], Predicate<T>)' DELTAV D:\Aperture-Delta-V\DELTA-V_HDRP\Assets\Scripts\DeltaVBase\AI_AgentSys\Sequences\Sequence_Assault.cs 55 Active

[wintry quarry]

FindAll needs a second parameter https://learn.microsoft.com/en-us/dotnet/api/system.array.findall?view=net-8.0

or rather

it needs a first one

Should be Array.FindAll(rallyPoints, CanUseRallyPoint);

[gritty notch]

oh ok it keeps going back to blank without finishing the animation i think

[polar acorn]

FindAll takes two parameters. You've only given one
https://www.geeksforgeeks.org/c-sharp-array-findall-method/

[wintry quarry]

then it's a problem with how you set up the state machine and/or the code controlling it

[vast vessel]

this is a list not an array, it takes on peram:
https://learn.microsoft.com/en-us/dotnet/api/system.collections.generic.list-1.findall?view=net-8.0

[wintry quarry]

according to your error it's an array, not a list. Show how rallyPoints is defined

[gritty notch]

would setting an exit time fix anything?

[wintry quarry]

maybe? It depends what you're doing and how your code works.

[vast vessel]

public List<Assault_RallyPoint> rallyPoints = new List<Assault_RallyPoint>();

[wintry quarry]

show the full script

something isn't adding up

the error clearly thinks it's an array

[open apex]

why do I feel bad when I take on the easy path 😭, rigid body has his own physics, CharacterControl has easy control over character but you have code physics to it

[vast vessel]

https://hastebin.skyra.pw/ozabevoxac.csharp

[willow nexus]

when i use Destroy(gameObject) on an object, the particles it has already emitted also get destroyed
is there another way to do this?

I'm instanciating a little light glow effect that shoots out some particles, but i want to remove it without destroying the particles its already made

[river pecan]

Destroy(gameObject, delay)

[wintry quarry]

Stop emission, don't destroy the particle system

[river pecan]

Or don't destory it yeah

[wintry quarry]

you can't destroy the particle system and expect it to keep rendering particles

[gritty notch]

my code is just this

animator.SetBool("Hit", Input.GetMouseButton(0) || Input.GetMouseButton(1));

[wintry quarry]

your code is not just that

it's a lot more than that
for example where is this line?

[willow nexus]

so i should separate the particle system onto a parent object
destroy the light child component
and stop producing particles then destroy the main one like 10 seconds later?

[gritty notch]

i mean the code to trigger that animation is just that

[wintry quarry]

You should'n't be using a bool to trigger an animation

you should be using a trigger

[river pecan]

If you really want to destory it, set the destoy delay to the lifetime of the particles

[willow nexus]

its being instanciated every time the player picks up an item so i have to destroy it
ill do this

[river pecan]

Destroy(gameObject, delay)

[hazy crypt]

guys I swear im losing my mind, my charater is flying off into the distance and I dont know why

[open apex]

{ 
private CharacterController _controller;

void Start()
    {
        _controller = GetComponent<CharacterController>();
    }
    
void Update()
    {
    Vector3 move = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
    _controller.Move(move * Time.deltaTime * Speed);
    }
    
}```

This is one example where CharacterController is used,
 And this is another, why would they use "GetComponent" if the game is solo and not multiplayer?

[river pecan]

set the delay to the lifetime of the particles

[hazy crypt]

void Update()
    {
        transform.position = rb.transform.position;
    }

    private void FixedUpdate()
    {
        rb.AddForce(transform.forward * forwardAccel);
    }

why does this make my object fly

is it olliding with itself?

[river pecan]

The rigidbody moves by itself

You're moving twice

AND

Adding a lot of force

[hazy crypt]

it should be gently rolling forward, but its flying off into the sky

[river pecan]

Set the velocity

Not add

[wintry quarry]

What on earth is the point of your Update function

[wintry quarry]

if it's rolling, you're adding force in whatever its forward direction is

which may be up

or down

[river pecan]

Actually

[hazy crypt]

The parent object is moving to the position of the ball

[wintry quarry]

it will change as it rolls

[river pecan]

You're not doing anything

with the update

[wintry quarry]

Well that's why

[river pecan]

I read the code wrong

depends on the rigidbody

[wintry quarry]

Child objects follow parent objects. So you move your parent, then the child follows, then you move the parent again...

[hazy crypt]

Im attempting to ollow this tutorial

[wintry quarry]

why are you doing this

[hazy crypt]

terrible screenshot

my bad

[wintry quarry]

I would guess you set up the scene incorrectly compared with whatever the tutorial is doing

[hazy crypt]

I thought the same but I cant see how

He has an empty game object with some visuals attached

then adds a sphere to add rb forces

https://www.youtube.com/watch?v=cqATTzJmFDY

If you have the patience

its 5 mins in

the objet setup is 2 mins in

[wintry quarry]

This is a weird setup

[polar acorn]

What does multiplayer have to do with it

[river pecan]

Yeah

[wintry quarry]

a child Rigidbody with a parent object that follows it?

😬

[river pecan]

Why not just add the rigidbody to the model?

[wintry quarry]

anyway without seeing what you did it's hard to say what's wrong

[river pecan]

Or have the model be the child

[hazy crypt]

very true

[wintry quarry]

maybe your parent object is rotated incorrectly for example

[hazy crypt]

I would love to find another solution to my goal but Im still a real beginner and this tutorial basically achieves it

[wintry quarry]

make sure this is on local so you can see which wat it's really facing

[hazy crypt]

I dont know enough to find a better solution

[rocky canyon]

u probably should have the rigidbody on the Player

[open apex]

forget about multiplayer, why would you do GetComponenet?
You can make the variable public and just drag to the script in unty

[rocky canyon]

and the collider.. the sphere should jsut be graphics
