[hexed pecan]

Have you confirmed that your ground check works while going down a slope?

Like does it return true

[heady iris]

I'm guessing you have a problem somewhere else. Maybe your ground check is wrong. Maybe vel is already compensated partially for your orientation and now you're double-correcting it here

[hexed pecan]

I can't pinpoint the problem but I assume it has to do with verticalMove + groundedness

[dense estuary]

Yes.

[heady iris]

if vel has already been rotated, rotating it again will give you a vector that points partially into the floor

[dense estuary]

Could it be me using transform.TransformDirection for the velocity?

[heady iris]

If your player is rotated to (at least partially) match the slope, then yes, that's your problem

in that case, you'd need to use Quaternion.FromToRotation(transform.up, slopeHit.normal)

rather than rotating from world +Y

you can use Debug.DrawRay to visualize what's going on here

[hexed pecan]

@heady iris video here

Character seems to be pointing up

[dense estuary]

The players x rotation doesnt change

[hexed pecan]

You mean X rotation

[heady iris]

oh, one important thing...

[hexed pecan]

Y rotation is side to side

[heady iris]

you should rotate the desired move vector, not the player's actual velocity

You're rotating your actual velocity

so if you're already moving down the slope, this tries to rotate your velocity vector 45 degrees into the ground

which slows you down significantly

[hexed pecan]

Good catch

[heady iris]

I've implemented this exact thing more than a few times 😛

[dense estuary]

yeah sorry

[hexed pecan]

Same, but it slipped past me

[dense estuary]

You mean do this?

[heady iris]

Correct.

[dense estuary]

instead of this?

[heady iris]

You want to adjust the intended movement

imagine you're already sliding down a slope

and you aren't trying to move

you shouldn't mess with the player's velocity at all

[dense estuary]

Currently I have this section to calculate acceleration, should I convert this into a vector three and rotate that then apply velocity? Because right now this is happening: https://streamable.com/555ffo

[heady iris]

The short arrow is the player's velocity. The long arrow is the velocity after running it through SlopeVelocityChange

[heady iris]

calculate the desired velocity, adjust it to fit the slope, and then do acceleration

[dense estuary]

That is what I am currently doing, and the thing in the video I just sent is the result.

[heady iris]

Show me your new code.

[dense estuary]

Here is my whole script rn: https://hastebin.com/share/usekocugez.csharp

[heady iris]

verticalMove needs to come out desiredVelocity.

that's not part of your actual move input

Break your original velocity into two pieces:

• the part that's aligned with the plane of the slope
• the part that's aligned with the normal of the slope

Use Vector3.MoveTowards to move the first part towards the desired velocity (which is constructed only from your move input).

Put the two pieces back together.

You'll need to know the slope normal to do that

Vector3 planeVelocity = Vector3.ProjectOnPlane(velocity, slopeNormal);
Vector3 normalVelocity = Vector3.Project(velocity, slopeNormal);

planeVelocity = Vector3.MoveTowards(planeVelocity, desiredVelocity, acceleration * Time.deltaTime);

velocity = planeVelocity + normalVelocity;

This gets around a major problem with the code:

        velocity.x = Mathf.MoveTowards(velocity.x, desiredVelocity.x, maxSpeedChange);
        velocity.y = verticalMove;
        velocity.z = Mathf.MoveTowards(velocity.z, desiredVelocity.z, maxSpeedChange);

This doesn't let you accelerate in the world Y axis

which means you're accelerating slower on slopes

[dense estuary]

but didnt you say not to rotate the velocity?

[heady iris]

This doesn't rotate the velocity vector.

[dense estuary]

Is that supposed to go in the SlopeVelocityChange?

[heady iris]

I left out the part where you calculate and correct desiredVelocity

        Vector3 desiredVelocity = transform.TransformDirection(moveValue.x, 0, moveValue.y) * speed;
        desiredVelocity = SlopeVelocityChange(desiredVelocity);

[heady iris]

But you need to know slopeNormal to do this correctly, so you'll need to grab that

[dense estuary]

I have it, from the raycast.

The player just went up a ramp super quick and back down super slow?

Here's what I got:

void PlayerMove()
{
    Vector2 moveValue = move.ReadValue<Vector2>();

    Vector3 desiredVelocity = transform.TransformDirection(moveValue.x, 0, moveValue.y) * speed;
    desiredVelocity = SlopeVelocityChange(desiredVelocity);

    Vector3 planeVelocity = Vector3.ProjectOnPlane(velocity, slopeHit.normal);
    Vector3 normalVelocity = Vector3.Project(velocity, slopeHit.normal);

    planeVelocity = Vector3.MoveTowards(planeVelocity, desiredVelocity, acceleration * Time.deltaTime);

    velocity = planeVelocity + normalVelocity;

    Debug.Log(desiredVelocity);

    controller.Move(velocity * Time.deltaTime);
}```

[heady iris]

doesn't your SlopeVelocityChange method check the sign of y?

            if (adjustVel.y < 0)
            {
                return adjustVel;
            }

yeah

so it's going to behave differently going up and down slopes

ah, and one other thing

[dense estuary]

Okay, well that fixed that problem, but now there is another. There is no gravity, I am just sticking to the ground.

Here is video: https://streamable.com/5sniy3

[heady iris]

verticalMove isn't being included

Just add gravity at the end. You don't really want to keep track of the vertical move separately

since your movement can now go in the +Y/-Y direction

A separate verticalMove made sense when your movement was strictly in the XZ plane

You will probably want to use controller.velocity to figure out how fast you actually moved

Alternatively, you can set normalVelocity to zero if it's pointing into the ground and you're grounded

That's a good fit for how verticalMove used to work

so verticalMove (which could only be in the Y direction) is replaced by normalVelocity (which can point in any direction)

on flat ground, they're exactly equivalent

[heady iris]

Give that a try.

The big idea is to get rid of "special directions" -- there shouldn't be an axis that behaves differently than the others

[dense estuary]

Like this?

[heady iris]

I'd just write velocity += gravityVector * gravityMultiplier * Time.deltaTime;

gravityVector would be 9.81f * Vector3.down by default

[dense estuary]

And I do that before or after saying velocity = planeVelocity + normalVelocity;?

[heady iris]

I guess I'd do it before splitting, but that's going to be a very slight change

[dense estuary]

Its currently applying the gravity along the slope or something, because I walked on the slope and flew super fast off of it.

Here is what I got:

void PlayerMove()
{
    Vector2 moveValue = move.ReadValue<Vector2>();

    Vector3 desiredVelocity = transform.TransformDirection(moveValue.x, 0, moveValue.y) * speed;
    desiredVelocity = SlopeVelocityChange(desiredVelocity);

    velocity += gravityVector * gravityMultiplier * Time.deltaTime;

    Vector3 planeVelocity = Vector3.ProjectOnPlane(velocity, slopeHit.normal);
    Vector3 normalVelocity = Vector3.Project(velocity, slopeHit.normal);

    planeVelocity = Vector3.MoveTowards(planeVelocity, desiredVelocity, acceleration * Time.deltaTime);

    velocity = planeVelocity + normalVelocity;

    controller.Move(velocity * Time.deltaTime);
}```

[heady iris]

hm, yeah, this doesn't have any friction

so gravity will send you careening off

See how it feels if you dramatically increase your acceleration. You should stop slipping off the slope

[dense estuary]

Yeah, its sending me off of the slope like a damn catapult rn, lol.

I step on the slope and slide up, but slower

Here is a video of it: https://streamable.com/3x095g

            }
        }
        wait = new WaitForSecondsRealtime(0.05f);
    }```

im trying to parse dialogue text and remove emotion prompts like [happy], [sad] etc

but for somereason Remove is reversed and the starting index is the end of the string and the characters to remove go backwards ?

like if im not mistaken Remove's first argument is the starting index then the second argument is the characters to remove after that

charaterIndex is 0 and token length is 9, but the beginning string isn't removed at all, a text like "[happy]Hello! how are you?" becomes "[happy]Hello! how"

[fervent furnace]

1. given start index s_idx and end index e_idx
   the length is e_idx-s_idx+1, then remove from s_idx with length e_idx-s_idx+1, no need to create substring
2. just move the pointer to index of ] +1

[cosmic rain]

Isn't the issue before it even gets to remove? You make substrings based on ]

Did you try stepping through the code with a debugger?

[fervent furnace]

wait, isnt the tmp text pointing to different string instance?

[hybrid orchid]

Why would it. ? doesn’t substring just take a piece from an existing string to a new variable based on index

[hybrid orchid]

Token is needed, since I’m needing to get the emotion name between the [ and ] im not done with this code but I want to get this working before I continue

Oh and characterindex does become ] + 1

[hybrid orchid]

no?

[fervent furnace]

TMP.text=a_str;//here a_str contains emtional prompts
a_str=a_str.SomeChanges();//.SomeChanges() returns new string, TMP.text still pointing to old a_str

[hybrid orchid]

oh my god im so dumb. that was my issue

Hello so for my game I gave the player some health and when a specific animation plays the player takes damage but they are immediately dying 😦 idk why https://hatebin.com/mmwsqomihu

[deft timber]

because you are substracting 50 health every frame your current animation is "Punch"

learn animation events

[opaque fox]

I tried but when i looked it up nothing came up

[deft timber]

then look better

basic googling skills

[soft shard]

What keywords did you try searching with?

[split stirrup]

any ideas why in webgl scenes transitions may not working( I appears in main menu, then push the play button and nothing happening(in unity editor everything ok))?

[deft timber]

make a debug build and upload it and debug

[split stirrup]

good idea

[opaque fox]

Well I made one of the animation events however it is saying it does not have a function name even though i set the method

[hard estuary]

What are the best practices in terms of refreshing nested Layout Groups?

[astral nexus]

how to handle UI state and its logic properly in unity? I know about MV_ family patterns, but its very sloppy to implement in the engine (at least for me)
I know it's more architectural question and I can do whatever works for me, but I just want to make "more clean" code, so I ended up doing UI manager that holds an internal event bus with all events and I just subscribe and fire these events by this manager interface
but I think there are more and more better ways of doing it, because all of my classes that interact with UI depend on this manager and its event bus
and it's very dirty and clunky to put this subscription and unsubscription all over the place in init logic of my scripts
maybe there are some resources or tutorials on this topic that you guys can share?

preferably for unit testing capabilities of UI classes

[cunning thunder]

Hey guys, I am far into multiplayer fps game development with Unity. I have been lately debugging my lag compensation code and it looks like one box collider is offseted little bit on server in comparison to client. (or my box collider drawing code does not work)

I am drawing using object's (which got the collider) position, rotation, lossyScale, and also box collider size + center. It also seems like lossyScale is different by about 0.001 even though it should be (100, 100, 100) on both.

My question is: how can I 100% accurately log a box collider into console? Do I just need box collider's center & size, and then the object's world to local matrix, instead of using lossyScale etc?

[orchid abyss]

why does it sound like that?

[deft timber]

how can we know?

[humble pumice]

We need a bit more info on that

Soundfile, code, settings in inspector

Code at least

[deft timber]

well look at your code

you are playing the audio every frame

when the health is below or equal to 0

[orchid abyss]

its a death sound

[deft timber]

and you are playing it every frame

[slow shoal]

Basically what you wrote is

[deft timber]

when the health is below or equal to 0

idk how can i explain this simplier lol

[slow shoal]

every update meaning every frame your music will play

[orchid abyss]

ah

[slow shoal]

if health is below 0

[deft timber]

learn events

make OnDie event, trigger it when unit dies

and subscribe stuff to that event

[thin aurora]

I assume you expect the sound to end when the object is destroyed, which is fair. However, you destroy it after the length of the sound has elapsed, and considering this code plays every frame it will invoke the sound every frame until the first Destroy call has its delay end

So instead destroy it immediatley and have the sound play on a separate gameobject, maybe

Or add a boolean to indicate this if-statement has triggered

[slow shoal]

Actually i wondered same too, even tho im not beginner

[deft timber]

it shouldn't be in Update

let's start from that

[thin aurora]

Depending on having a gameobject destroy itself so the update statement doesn't trigger is kinda bad to begin with

[slow shoal]

Like detect in update, and then run only once

[deft timber]

perfect event use case

[slow shoal]

How can you do that

[thin aurora]

A boolean variable?

[deft timber]

things like that shouldn't be handled in Update

[reef cobalt]

I usually have a SoundManager empty GO that I use for all my sounds for this reason

[slow shoal]

Yeah but that's just a poor solution

I think there are better solutions

[thin aurora]

Having it in an Update statement is the actual problem though

It should be an event handler

[reef cobalt]

I agree

[orchid abyss]

what is event handler

[thin aurora]

dealDamage should trigger an event that indicates the object died, or instead that it took damage. Then have another script handle the sound if the health reached 0 or lower

[thin aurora]

Look up UnityEvent

[deft timber]

well

[orchid abyss]

aight

[deft timber]

i just said that 3 times already 😄

[thin aurora]

My bad

Or make the simple fix of checking health in dealdamage if you don't want the added abstraction

[slow shoal]

And it only runs once, correct?

[dusk apex]

Maybe consider evaluating and setting the object for destruction after decreasing health.

[thin aurora]

And please consider using proper .NET conventions when writing code. This is pretty bad...

[slow shoal]

Imagine how life would be easier if discord also included line count

[lucid tulip]

BetterDiscord has a plugin for that

It's called Enhance CodeBlocks

Hi guys,i have a question,i have to draw a vector but rotated,how can i do it?

i have to rotate it of 180 degrees in the x axis

[slow shoal]

Depends how you want to rotate it

[lucid tulip]

https://docs.unity3d.com/ScriptReference/Quaternion.AngleAxis.html

[green ice]

My question is can i do it?

[lucid tulip]

Yes

[thin aurora]

Quaternion.AngleAxis or Quaternion.Euler

[quartz folio]

Multiply it by a quaternion that expresses the offset you want

[slow shoal]

Here take this graph

[lucid tulip]

Good graph

[green ice]

Can you give me an example

[slow shoal]

Vector(1,1) is diagonal on the right upper side

for example

[kind pivot]

anyone know if there's a way to reset rich text in a string? like if the first part of a string is in rich text but I don't want the next part to be and I don't necessarily know what tags that were used so I can't just close them (user provided)

[astral nexus]

I have simple action map for UI and EventSystem component set up with Input System and it works just fine, but when I disable this action map - it still register input to IPointer_xxx_Handler and its callbacks being called just as it was enabled, but it's not
am I missing something? why its calling this callbacks even when action map is disabled?

[lucid tulip]

string nonRichTextString = Regex.Replace(richTextString, "<.*?>", string.Empty);

[kind pivot]

was afriad of that... was hoping for a more supported solution like a reset tag of some kind

[lucid tulip]

Afraid why?

[quartz folio]

well, any robust solution would have to be much more involved than just that

[thin aurora]

Regex is not that bad, just don't do it inline like this

Because this is slow

There are libraries that can generate code to replace a regex query, I believe it's even is base .NET

[kind pivot]

I would just prefer not to use regex as there's always a chance it'll capture user input unintentionally possibly without a means of escaping it

[lucid tulip]

You could make a list of all the rich text tags and replace those with nothing

[kind pivot]

but I had seen a few use it as a solution on forums so I was fearing that was the only way to solve it

[quartz folio]

Consider, two parallel fields, one with rich text enabled, the other not?

[kind pivot]

but the text needs to be side by size so I'd need to adjust it using horizontal layout? idk how that would even work with multi line inputs

[thin aurora]

You mean users writing something using < and >? I know base HTML formats user based characters like these as to not conflict with actual tags, I'm not sure if Unity does the same

[quartz folio]

I don't use UGUI any more, so I have no good answer for that one lol

[kind pivot]

UGUI?

[quartz folio]

Unity UI

[kind pivot]

ah

[quartz folio]

I was just hoping that you might have a simple enough case where it would not be bad

[kind pivot]

tbh I'm considering just disallowing all rich text with the noparse tag. but this is more if I wanted to allow it in the future

[kind pivot]

unfortunately not. I could limit the size of the first text but the second text is of unspecified size so it can span multiple lines to fill out a container

[modest lion]

dafuq does that mean

[ripe cove]

hello im having troubles with making scripts for each level of difficulty of the game we're developing, can someone help me? 🥹

we're currently developing a game and our game is inspired from decked out 2

you may or may not be familiar with the game, but its a good one!

https://www.youtube.com/watch?v=aoVVCwx6k1w&pp=ygUMZGVja2VkIG91dCAy

[soft shard]

Never heard of that particular game, though what issues are you having? If you have specific questions, im sure someone may be able to help (though it is quite late in this part of the world, so it could be some time for others to see your message, generally though, more details are better to help with)

[ripe cove]

So in our script 'HardDiff.cs', which is the script for hard-coded parameters for every dungeon (based on thei difficulty), every difficulty has different parameters. We're gonna put it in a single script for button event in onclick(). Now, we will inherit those parameters from different scripts such as RoomFirst script, RWalkDungeon script and Abstract Dungeon script. The RoomFirst script, is for the room and dungeon partition, then RWalkDungeon is for random iteration and the Abstract dungeon is for clearing the dungeon every generate.

So the predetermined parameters are:

Easy
Min Room -W - 10
Min Room - H - 10
Dungeon - W - 70
Dungeon H - 70
Offset - 2
Iterations - 50
W Length - 15

Medium
Min Room -W - 20
Min Room - H - 20
Dungeon - W - 150
Dungeon H - 150
Offset - 3
Iterations - 100
W Length - 25

Hard
Min Room -W - 20
Min Room - H - 20
Dungeon - W - 250
Dungeon H - 250
Offset - 4
Iterations - 200
W Length - 60

The issue is that there is a script 'DungeonData.cs' which is for the parameter editor for RWalkDungeon. We made a 'Hard' button to try. But it wont generate a dungeon.. here's the code.

here are the parameter script for RoomFirst script, RWalkDungeon script, Abstract Dungeon script, and DungeonData.cs

[soft shard]

One suggestion I can make, if you want to simplify some of your repeat variables across the various scripts, you can put them all in a class, if you serialize that class you can populate it from the inspector, and if you put that serialized class into a ScriptableObject, you can even create assets of that data to reference on various objects, for example:

[System.Serializable]
public class SomeData
{
public string name;
public int health;
public float speed;
}

[CreateAssetMenu()]
public class SomeDataSO : ScriptableObject
{
public SomeData data;
}

public class SomeImplementation : Mono
{
public SomeData data;
public SomeDataSO so;

void SomeFunc()
{
Debug.Log(data.health); //assigned from inspector
data.health = so.data.health; //assigned from asset, referenced from inspector
}
}

This alone wont solve the issue you described, but it may help just having to only add "SomeData" to scripts, or referencing just a "SomeDataSO" in case your designers wanted to change the numbers at any point without having to dig through specific objects and scripts

[ripe cove]

okay will try that right away, thank you!

[raven ibex]

Hello, does anyone know how can i crop extra alpha pixels in a Texture2D in runtime, akin to Trim option in Photoshop?
I need to do that to preview the images, because otherwise the full image is going to be scaled down and hardly visible
At the same time i can't change the source image, because it's used in full for overlaying purposes

[knotty sun]

probably more efficient to just make 2 images

[raven ibex]

Yes, i'm considering this ATM, i was just wondering if cropping would be a better option, so i could keep the image clutter minimal
Thanks for responding!

[knotty sun]

it's not difficult to do but it is time consuming
you scan the pixels and make a bounding box for the non alpha pixels then you make a new texture and copy the pixels inside the bounding box into that

[deft dagger]

hey, is there a way to make tab between input fields ?

[raven ibex]

so essentially i need to find pixels with value not equal to zero and go from there?

[knotty sun]

with alpha != 0

and use Color32 not Color

[raven ibex]

alright, thanks!

[thick terrace]

if this is for something where you can use sprites, you could also look at doing this in the sprite editor? so you create a sprite of the middle part not including the transparent border, then use the full image for the overlay

[raven ibex]

i'm afraid not, the images are not stored in the project

[thick terrace]

you can create sprites at runtime too actually - you just need to give it the texture and rect

[raven ibex]

i don't really understand the benefit of this if i'm working with just the texture

but thanks for the suggestion

[thick terrace]

you haven't specified how you're displaying the images, but it'd be a benefit if it was a UI Image or something like that, because creating a sprite would be cheaper than copying a whole texture

[quaint rock]

they mentioned sprite since you can define a rect on a texture of the part the sprite should be of

though first thigns first how are you wanting to use this texture?

if you wanted to trim a texture and not make a sprite on it, you would create a new texture of the target size then copy only the pixels in the range you care about to it

[raven ibex]

the original texture is added into the template, so the output would be the combined texture, that is then used for an image

[quaint rock]

yes but are you displaying this on a model

in the UI

[thick terrace]

in the end a sprite is just a way to tell it to render the texture with the right UVs to display a region of the image, so whether or not you can use a sprite, that's an option if performance is important

[quaint rock]

via a sprite renderer?

[raven ibex]

UI image

[quaint rock]

you want a sprite anyways then

[raven ibex]

yes, but isn't that a final stage though?

[quaint rock]

since UI image does not use texture directly, so you can simple create a sprite that displays 1 area of your texture

[raven ibex]

i simply don't know how to make this to be honest, so i'm just tinkering with the source texture

[quaint rock]

if you are deadset of doing it in the texture, there is no trim function, what you do is create a new Texture2D at the wanted size, then copy what you need from the old texture into it

https://docs.unity3d.com/ScriptReference/Sprite.Create.html
the sprite method for this
doing it the texture way is a little more complicated

[knotty sun]

The trick is to calculate the Rect, what you do with it, Create Sprite or make a new Texture is not so important

[raven ibex]

i see, thank you for the help, i'll try to figure it out with what you provided

[worn pecan]

Hey guys, can you teach me how to make a player teleport?

[knotty sun]

you put it in your code at the point you want the player to teleport

think you maybe should work on the basics first and learn a little about how C# and Unity work

[worn pecan]

I do know how unity works. Only abt the coding i get stuck with. I take all my code on github or youtube tutorial

[deft timber]

so you blindly cpoy/paste code

without understanding it

right

[worn pecan]

Yeah...

[quaint rock]

you are asking for a video on how to set a objects position, that is like the first thing people learn

[deft timber]

and you think it's a good way to learn things?

[worn pecan]

I'm still learning coding at school🙃

[deft timber]

how is that related

to what i just said

[quaint rock]

like i am not trying to be harsh, but you have to put the effort into understanding things to use it

[worn pecan]

Aight.

[quaint rock]

all introductory lessons on unity and C# will show you how setting positions works which is what a teleport is

Can I set the "Build Configuration" and "Script Debugging" parameters in the build settings tab from script? I've been looking around EditorUserBuildSettings/EditorBuildSettings/PlayerSettings and I don't seem to be able to find anything relevant. I did find the necessary development flag I need to enable script debugging, but not the actual flag

[knotty sun]

https://docs.unity3d.com/ScriptReference/BuildPipeline.BuildPlayer.html
https://docs.unity3d.com/ScriptReference/BuildPlayerOptions.html
https://docs.unity3d.com/ScriptReference/BuildOptions.html

[deft dagger]

hey is there anyway to make the tab button switch between input fields ?

[dire elm]

https://docs.unity3d.com/2018.1/Documentation/ScriptReference/UI.Selectable.Select.html

[thick terrace]

i think you have to do the input handling for the tab key yourself but the field switching is something like this:

var selected = EventSystem.current.currentSelectedGameObject.GetComponent<Selectable>();
if (selected) {
  var next = selected.FindSelectableOnDown();
  if (next) {
    EventSystem.current.SetSelectedGameObject(next.gameObject);
  }
}

[vital aurora]

I don't see any reference to Script Debugging or Build Configuration settings here. I'm also hoping to not have to launch a build, just toggle those settings. The development flag can be set with a simple:

EditorUserBuildSettings.development = value
I'm hoping to find these values similarly without having to launch a whole build

[knotty sun]

BuildOptions has the Development and AllowDebugging properties but I guess you need to use BuildPlayer via script to use them

[vital aurora]

EditorUserBuildSettings.allowDebugging was exactly what I was looking for thanks. I was looking for the words they actually use in the GUI like an idiot

Still need to find that Build Configuration setting and then I can close this task

[knotty sun]

do you mean the activeBuildTarget and the various subTargets ?

[hard viper]

I am moving my project folder with my unity project from a mac to a new windows machine. Is there anything I should know to ensure a smooth transition?

[knotty sun]

best to use Export/Import

[real falcon]

What's a good way to move the player other than transform

[hard viper]

wdym

Unity hub has an “add project” button to add project from folder

but that sounds like a different feature

[knotty sun]

Asset->Export on Mac to create a .unitypackage Asset->Import on Windows to read said pakage

[hard viper]

gotcha. and this is on UnityHub or in UnityEditor?

[knotty sun]

Editor

[quaint rock]

there is no need to export

just delete the library and temp folder after copying the project folder over

[hard viper]

i just want to send over to ensure as smooth of a transition as possible

[quaint rock]

yeah jsut copy the whole project folder and delete the Library folder in it

[hard viper]

i assume an explicit export/import is designed to handle that

i’ll give each a shot. The only thing I have to lose is a little time

[quaint rock]

at work we are using a mix of macs and windows and it all works fine. using git which ignores the few folders that are generated by unity and its all seamsless

[chilly surge]

Refer to Unity’s gitignore template to see which folders are useless.

It’s as simple as copying over only the actually useful ones and just open it on the new machine, nothing much else is needed.

[quaint rock]

even i have both machines on a kVM and swap between on the same project at times based on what i am building for. like need windows to build for switch for example

also i heavily recommend learning about version control and Git

[hard viper]

ty. I’ll need to check it out

i guess on a different note, let’s say I have a mac and a windows PC, and I want to be able to interchangeably work with either on the same project. What is the best way to sync everything?

github?

[chilly surge]

Any version control.

[quaint rock]

any version control

though Git with Github are most popular

[hard viper]

which would you recommend?

I haven’t done ssh since my college years

don’t even remember what it stands for. just have that memory lol

[knotty sun]

no need to sync anything, make a shared drive on Windows or Mac and just use the same project

[quaint rock]

really once the ssh key is setup its not something you have to worry about again

[chilly surge]

I personally use git yeah, but supposedly it doesn’t work that well for large binary assets. My projects don’t have a ton of large assets for me to really know if that’s true.

[quaint rock]

i setup the ssh keys for git on my mac like 5 years ago and never touched it again

@knotty sun shared drive would be very bad for this due to the Library folder

[latent latch]

local repositories for larger assets

[quaint rock]

would need to nuke it everytime and let it regenerate which is a waste of time

[hard viper]

i see. is there a guide/resource/tutorial on how to best set this up?

i think you are saying to set up a git with an ssh key.

[knotty sun]

works for me, I have the same project being used on Mac, Windows and Linux all from one shared drive

[hard viper]

they probably all do work. but version control is probably better to revert

[chilly surge]

For git, it shouldn’t be much different from other projects. Have your credentials setup, have the Unity’s gitignore template setup, then just commit/push/pull/etc like you normally do.

[knotty sun]

you should have version control whatever else you do

[hard viper]

yeah, I’ve been bad

[quaint rock]

you get other bonuses with a full VCS system too, since you can revert to past versions easily and see diffs which makes tracking down bugs much easier

[hard viper]

are there any privacy issues?

[quaint rock]

can work on features in isolation from other changes and easier collobration

depends on where you host it, but pretty much any provider will have private and public repos

[knotty sun]

only, if you use Github, MS will steal your project to train their AI models

[quaint rock]

so just use a private one

they only do that with public repos not private

[chilly surge]

Also to note git is not tied to GitHub/GitLab/other hosts, you are free to use git completely offline or self host if you want.

[hard viper]

so i should use git

[quaint rock]

yeah git is the system and protocal GitHub,GitLab,Bitbucket etc are all just cloud providers for the remote

some people might recommend unitys vcs system, but i greatly prefer Git, and its the standard for most software development these days

gamedev and animation are the main exception where Git is not the defacto choice, but still common in this domain

[real falcon]

cough

[vagrant blade]

Use a rigidbody

[quaint rock]

that is not really a good question unless you say what your intent is and why you need to move it in a other way

[hard viper]

ty all.

[quaint rock]

like if you want to use physics use a rigidbody, if not use a transform

[real falcon]

How do you use a rigidbody as I tried that and it didn't move

rb.AddForce(moveDir.normalized * moveSpeed * 10f, ForceMode.Force);

[rancid basin]

i got a climbing script in unity for VR but it should be the same as for 3d just the hand being the player so im asking this here and i have some issues with it.

the first issue is that if i start climbing on a object i get teleported a little before my hand is at the position it should be again.

the second issue is that its responding too slow. its smoothing my movement out which it shouldnt it should be moving my player exactly when im moving my hand too.

this is the part that is handling the climbing which is in my FixedUpdate() void:

Vector3 deltaPosition = currentObjectClimbingOn.position - lastHandPosition;
        rb.MovePosition(rb.position + rb.transform.rotation * deltaPosition * 10f * Time.fixedDeltaTime);
        lastHandPosition = transform.position;```

i already tried removing the Time.fixedDeltaTime and also tried changing the multiplier from 10f to something like 100f or 1f but with 100f or no Time.fixedDeltaTime im getting flung around and with 1f the movement is even slower.

[deft dagger]

thanks man it worked

[hexed pecan]

Does it need collisions?

[real falcon]

yes

[hexed pecan]

Oh seems like you are trying a rigidbody already

[storm thorn]

Hi! Do you guys have any idea for pdf generator in unity that can work on android?

[real falcon]

Yeah, I've got this rb.AddForce(moveDir.normalized * moveSpeed * 10f, ForceMode.Force); Physics.Simulate(Time.deltaTime); (surely this doesn't count as big enough to be put in hastbin) but it doesn't seem to do anything and I don't know why

[hard viper]

is your rigidbody dynamic

[real falcon]

no

[hard viper]

then add force will never move it

it is not affected by forces

[hexed pecan]

^ Also why are you calling Physics.Simulate manually

[hard viper]

also you should not need to call Physics.Simulate unless you have an extremely good reason to, which you don’t

[real falcon]

the docs said something along those lines

[hard viper]

well, I’m telling you no

Physics.Simulate runs the entire physics simulation by that timestep

[real falcon]

play still can't move

[hexed pecan]

Which doc 🤔

[real falcon]

unity I think https://docs.unity3d.com/ScriptReference/Rigidbody.AddForce.html

[hexed pecan]

This?

[hard viper]

Unity by default runs Physics.Simulate(fixedDeltaTime) at the right time, every fixed frame

do not call Physics.Simulate unless you are making a custom physics system or something.

[real falcon]

rb.AddForce(moveDir.normalized * moveSpeed * 10f, ForceMode.Force); I have this in void Update but nothing happens and I also have this for input system if (Input.GetKey(KeyCode.A)) horizontalInput += 1f; if (Input.GetKey(KeyCode.D)) horizontalInput += -1f; if (Input.GetKey(KeyCode.W)) verticalInput += +1f; if (Input.GetKey(KeyCode.S)) verticalInput += -1f;

[hard viper]

1. If your rigidbody is not dynamic, adding force will never move it

2. you have not checked if the vector going into Addforce is non zero, which is a separate check

[real falcon]

does this mean setting collision detection to continuous dynamic

[hard viper]

that is a different setting

i’m talking about dynamic vs kinematic

[real falcon]

well it's got kinematic off

and there isn't a dynamic option

[hard viper]

for 3D, not kinematic means dynamic

check the vector being passed in to add force

with Debug.Log

if the vector is small or zero, that needs to be resolved first

[hard viper]

and the script is on a monobehaviour on the object

and the addForce is in FixedUpdate

[real falcon]

the script is NetworkBehavior

[hard viper]

but does it derive from MonoBehaviour

[real falcon]

yep

I think

[hard viper]

how do you not know

you wrote it lmao

[vital aurora]

sorry this is a WSA setting I can't find... Build Configuration it swaps between Debug/Release/Master

[real falcon]

no its from netcode

but also I control clicked it in visual studio and the file defining it was monobehavior

[hard viper]

before you try importing any code into unity, you should at least know the basics, man

you don’t know how to drive, and you’re on the highway

[real falcon]

I can still walk confidently

[hard viper]

start by writing code from scratch without importing

[real falcon]

I mean I did a bit of that

[hard viper]

you should be putting the whole script in hastebin tbh

[real falcon]

I gtg now but thanks for the help!

[full sail]

so i got this track that i made with splines out of a prefab which looks like a hollow cube, but i noticed that there are overlaps between tracks in narrow parts, and large gaps in sharp turns, so i reduced the distance between them and tried to link the vertices with probuilder but i later realised when i baked the instances that there are more than 150 instances that i need to link vertices of, and not only that but you can't "Weld Vertices" of two different gameobjects anyway, so i am asking here is there a way to link the track visually in a way that 1. won't need me to join between gameobjects (because i have some logic that uses the rotation of each gameobject and it's transform.forward to determine camera rotation) and 2. something that wouldn't need me to go making an algorithm using the Mesh class and merging vertices that way since i don't know a lot about it and it can break in a million ways with normals, lighting, texture etc...

[glossy wave]

Hello! I am trying to make my Enemy detect the Player using a Spherecast, but it doesn't seem that the Spherecast is hitting the Player, because I'm not seeing the Debug.Log() message. In the screenshot, the transform gizmo is the origin of the spherecast (raycastOrigin.position in the code), and where the arrow i drew points to is the origin of my Player (player.transform.position in the code).

        raycastDirection = raycastOrigin.position - player.transform.position;

        if (Physics.SphereCast(raycastOrigin.position, 0.05f, raycastDirection, out hit, raycastDistance))
        {
            if (hit.transform.CompareTag("Player"))
            {
                Debug.Log("<color=red>Enemy sees player!</color>");
                result = true;

Guys lets's say that a person uses the method LookAt() but looks that target objects with the back of the head,how can i look the tarket object with the front of the head?

[steep herald]

I think you already know the answer, it's the one you're so desperate to avoid. It's really not as hard as you make it out to be and for the rotation, you can get it from the spline instead of per-game object. You'll get smoother results anyway.

[hard viper]

1. check the tag
2. check what the spherecast hits, player or otherwise

[full sail]

Joining game objects and welding vertices or using the mesh class? Also how can I get it from the spline, that was originally what I wanted to do but I couldn't find a way to get rotation at x,y,z position. And I tried with spline animate but I still couldn't get such properties

[hard viper]

3. spherecast only returns 1 hit when you want a boolean output

so if you have multiple hits, and the first one isn’t the player, but the enemy, it will return true with a hit of the enemy

also, your spherecast should restrict search to relevant layers

[steep herald]

Generating a mesh dynamically.

I don't know the unity spline system but generally you break down the spline into a polyline with smaller segments who's lengths are closer to even. It's useful for navigating the spline at even speed if you're using the actual spline for navigation.

You can get the spline's forward vector by sampling the spline/polyline at ((p + some small value) - p).normalized. I'm sure unity already has something for this tho but I can't speak to it.

as for the mesh generation, under its most basic form

• sample all points (or break down into polyline and figure out the target length for the resolution you want)
• figure out the width you want, find the forward vector at the position of point and create verts at -perpendicular vector * halfWidth, another one at perpendicular * halfWidth.
• If you want your road to have thickness, offset 2 more vertices based on those vertices and the relative up negated
• repeat for all points
  then just read the mesh generation doc, it's like a 5 minutes read, it'll explain the order of triangles and a few more things that are really simple to grasp but seem scary in nature

[glossy wave]

Thanks. The raycast was hitting the Enemy's eye. I have now set those' layer to Ignore Raycast, and my freshly created Debug.Log() confirms that the spherecast isn't hitting them. It now appears that the spherecast is going in this direction:

[hard viper]

yeah, I would use a method that returns a list of RaycastHit, and then sift through to find valid hits

I would also include a layer mask, because the enemy’s eye should be on a layer that does not get included in your query, probably

[glossy wave]

Thanks

[tardy crypt]

when you have a regression and then notice you have no idea why it occurred because your code is spaghetti...

i hope everybody is ok with me sharing my stupidity

[rigid island]

You probably have the wrong pivot

eg your Forward is wrong

[green ice]

Yes,by default the pivot is wrong

Is there a way to fix it?

[rigid island]

make a parent with the correct pivot, rotate child until matches correct pivot

show your current object, make sure Local / Pivot mode is selected

[green ice]

Can i write you in private?

[rigid island]

no but you could make a thread here if you want

[green ice]

I will try later thanks

no but you could make a thread here if

[prisma birch]

How can I exclude an object or component that is part of a prefab from being recorded as an override?

[hard viper]

i’m not sure what the use case is here

it’s in the prefab, so you want it to come with the prefab. But you want to make edits to it, and not log that it is editted?

[prisma birch]

I have instanced materials on the object that need to be unique per object

So as soon as I add the object to a scene it comes with an override

[leaden ice]

What's the issue with it having an override?

[prisma birch]

That it makes the object appear to have been modified in the scene, but by nature it will always appear overridden

[leaden ice]

Also I assume you mean when you add it in the editor? I guess you have an editor script doing the material instantiation?

[prisma birch]

Yes

[leaden ice]

Well it is overridden...

[prisma birch]

I know

But I'd like to ignore that specific override

[hard viper]

why

[leaden ice]

But then the material change won't be saved right?

[prisma birch]

so I can more properly track prefabs that have been truly overriden

[hard viper]

to not be overriden means it matches the prefab

[hard viper]

but you did override it

[prisma birch]

but it can't match the prefab because the material is instanced on the prefab

so it will always appear overriden

[hard viper]

i just don’t understand what the issue is here

it is overriden, because you did override it, and that it why it appears overriden, because overriding is what you did

i feel like I’m talking to patrick star

[prisma birch]

The issue that I would like to ignore specific overrides, I'm not asking you to understand the specifics of my project

[reef garnet]

Hi I'm working on my own custom input tool that builds on top of the input system that uses scriptable objects as events. Now conventional wisdom says that I won't be able to do exactly what I want to do without some sort of grouping (list, array, etc...), can you loop through every reference of a type of variable in a script? I want to use it to automatically generate the event scriptableobjects. In essence I want the function to go through these variables in the image below and create an event object with the same name and then assign it.

[prisma birch]

being able to know when an object is overriden is useful but this specific prefab will always appear overriden and it's an override that I don't care about

[hard viper]

you mean you want to be able to modify the prefab, and propagate it only to specific instances, based on the contents of the material field?

then whatever editor script you made needs to explicitly check for that. probably OnValidate

[rigid island]

put them in array

[reef garnet]

Yeah that is the obvious answer, just wanted to see if it was viable without

[hard viper]

you are asking for Unity’s prefab system to propagate changes in a way that is more tailored to your specific use case, which diverges from the standard

and that is ok, but that requires specific code for it

[knotty sun]

use Reflection

[hard viper]

i think I would use a singleton non-SO

storing events in an SO during runtime for transient input events sounds like bad juju

[heady iris]

Reflection would allow you to iterate over all of the members of the type, yes

I have a vaguely similar situation where I need to both have specific fields and have a list of all of the things in the fields

in that case I just accept the duplication and make sure I put things both in a field and in a list

(I have an editor script that verifies this, through reflection)

[reef garnet]

Yeah cuz putting it into a list makes things a lot harder in general

[heady iris]

I could probably just switch to using reflection at runtime.

[hard viper]

reflection is the way to go here

[craggy veldt]

TypeCache should be faster than reflection, use that instead of reflection

assuming it's for edit-mode

[hard viper]

anyway, the bigger thing is: you probably don’t want to use SOs for this

[craggy veldt]

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

[heady iris]

ah, so it just caches the results of reflection for you

handy

[craggy veldt]

it's way beyond that, it's natively cached

[timid depot]

another unity bug (i think so?) that makes making this door even harder

[reef garnet]

So long as there is a reference in the scene then all the function run fine

[timid depot]

im slowly starting to hate this game engine

[west lotus]

What exactly is the bug here ?

[timid depot]

look at limits

when I de-active element and re-active it

limits are relative to current local rotation

you can't imagine how long i've been debugging it for

[west lotus]

Hmm that does indeed look like a bug. File a bug report for it

[timid depot]

where can I do that?

[craggy veldt]

😄

usually when people say that, they will still using it for years

[hexed pecan]

Sounds like your player model is just backwards, better fix that

Oh sorry I was scrolled up

[thin oxide]

I'm already going crazy

the same script that perfectly found the object I want, it says it doesn't exist

how is this possible

HOW find something that doesn't exist

[rigid island]

probably a copy then ?

[timid depot]

I hope so

it suits best my game and there's nothing better (maybe unreal but for graphics)

[craggy veldt]

I'm using both for work, UE ain't as nice as what you're seeing or heard either.

[thin oxide]

I tried to delete it and even everything from scratch again, it still has the same problem

[spring creek]

Type "t:RadioSystem" in your hierarchy search

[spring creek]

That wouldn't help with a copy of course

[timid depot]

I know that, for me it has only good graphics but its not that good for games

[real falcon]

if a rigidbody is restraining rotation of an object, how can I make a script follow these constraints as right now it is just rotating freely

[spring creek]

The constraints only stop rotation from forces

But not from you moving it

[real falcon]

how can I change that

[spring creek]

You cannot

You just have to clamp rotations yourself

[real falcon]

can I rotate it through the rigid body

[spring creek]

If you have a rigidbody, yes you should rotate it with the rigidbody, and ONLY the rigidbody

[real falcon]

how

because I tried rigidbody.rotation but it was still not following the constraints

[hexed pecan]

try rigidbody.MoveRotation

Not sure if that respects constraints 🤔

[spring creek]

I'm almost certain it does not, but it was a while ago that I tried

[hexed pecan]

AddTorque does at least

[real falcon]

it doesn't

[spring creek]

Other option is rigidbody.rotation
And yeah, AddTorque

[hexed pecan]

They tried it

[rigid island]

AddTorque cause iirc is similiar to addforce no?

but rotation

[spring creek]

Oh, they asked how to rotate with a rigidbody, so I didn't think they tried anything, and instead did it with transform

[real falcon]

how do I turn my quaternian for rotation into a vector 3 for addTorque?

[rigid island]

euler

[hexed pecan]

Quaternions have .eulerAngles

Note that you shouldn't just plug in the target rotation in it

You need a difference from your current rotation to the target rotation

Just like you don't give AddForce a position, you give it a direction/force vector

[real falcon]

would it be easier to just clamp it?

[rigid island]

you havent even explained your usecase, how can we know whats better /easier solution

[real falcon]

it's a playercontroller with a rigidbody

[hexed pecan]

Just to make sure - it doesn't have a CharacterController component right?

[real falcon]

It did but it seemed to make the character go flying randomly

[hexed pecan]

Yeah rigidbody doesn't work with CC

[rigid island]

well yeah its collidng with rigidbody (making rb fly off)

[spring creek]

Yeah, they cannot be used together

[real falcon]

found that out the hard way

[spring creek]

How do you move normally?

[rigid island]

they are different physics objects thats why

[spring creek]

AddForce, Velocity, or MovePosition

[hexed pecan]

This is probably a valid option tbh

[real falcon]

rigidbody.addforce

[hexed pecan]

Try MoveRotation with clamped angles

MoveRotation respects interpolation while rotation does not

[real falcon]

I'm not sure how to clamp the character without clamping the camera because it's first person

wait nvm

[split plover]

does anyone have a good solution for hiding changes to files that need to exist in the repo but that do not really want to have changes made but for which unity makes changes often (eg, a material which has a property set in play mode) - technically we could clone the material but its kinda a pain to update references since its used in a ton of places. I previously wrote an onquit script to revert it but it looks like that has broken. I'm thinking of trying git assume-unchanged or git skip-worktree

[real falcon]

``` Why can't I do this and how would I clamp the x rotation of this object (camera)

[heady iris]

so, two things

transform.rotation.x is not an angle. It's the X component of a quaternion.

and that's an error because transform.rotation is a property, which returns a copy of your current rotation

modifying this would be pointless, so you get an error

[real falcon]

so how would I do this

[heady iris]

I would suggest storing the desired rotation for the camera in a float

[wicked river]

I can't seem to see a channel where I would ask about Muse Behavior so I will ask her and anyone can just point me to the correct channel.

I am currently trying to learn how to use my own sysorySystem script with the muse Behaviour tree. I keep getting a null reference when trying to gain access to the script.
Any info, links or tutorials on the topic would be highly appreciated .

[heady iris]

You can try to clamp the euler angles of the transform, but this can cause some unwanted behavior

for example, -30 and 330 are equivalent

So you might wind up being unable to look down if transform.eulerAngles spits out 330 instead of -30

[heady iris]

instead, store the desired pitch (X axis rotation) and yaw (Y axis rotation) as float variables

then just set your rotation directly

[real falcon]

well all I need from this script is to stop my fist person player from looking too far down or up

[heady iris]

transform.rotation = Quaternion.AngleAxis(yaw, Vector3.up) * Quaternion.AngleAxis(pitch, Vector3.right);

that's how I do it

I think Quaternion.Euler(pitch, yaw, 0) would also work but I'm not 100% on that (maybe the order of operations will be wrong?)

[rigid island]

muse behavior tree ?

[wicked river]

well, ya

Muse Behaviour

[rigid island]

someone's actually paying for that?

[wicked river]

It's free...

[rigid island]

muse is a subscription

I cannot even find docs for Muse behavior so 🤷‍♂️

[heady iris]

i was trying to read about that

[wicked river]

Ya that is why I am here

to ask

[rigid island]

typical unity

[heady iris]

i could only find a really trivial example

[rigid island]

release half-baked features with no to little docs

[wicked river]

I just need to figure out how to gain access to scripts

The NPC is fully patrolling already

[rigid island]

hard to know what the methods are withou docs 🤷‍♂️

[wicked river]

just need to learn to get access to my scripts via blackboard keys

[wicked river]

true

there are docs though

[rigid island]

link me

[wicked river]

1 sec

[wicked river]

https://docs.unity3d.com/Packages/com.unity.muse.behavior@0.5/api/Unity.Muse.Behavior.Samples.html

[wicked river]

https://docs.unity3d.com/Packages/com.unity.muse.behavior@0.5/api/Unity.Muse.Behavior.html

It is also free to use

I have no subs

Muse AI needs a sub but this does not

[rigid island]

if thats true, prob because its pre-release

but be assured Muse IS a paid sub

[wicked river]

The AI I am building is rather complicated and behavior trees seems to be the only option

[rigid island]

also you need to show which line of the script is throwing you NULL

[rigid island]

well yeah behavior trees are quite complex

[wicked river]

My bad.

[rigid island]

you did not assign SensorySystem a variable name

[wicked river]

Ya so the variable is Balckboard<Variable>

or I think it's suppose to be

[hexed pecan]

It was correct here

[rigid island]

SensorySystem = // stuff
instead of SensoryStem sensorySystem = // stuff

[wicked river]

I thought so to but it through the null

[rigid island]

well you certainly dont fix a null by removing the variable name xD

[rigid island]

Agent or Value is null then

[wicked river]

again, I thought I would assign it like the others as a blackboard

[wicked river]

That's not it

Value is null though

so I assume

we don't get references like that

[rigid island]

"thats not it", meanwhile Value is null lol

go for it if you'd like

trying to find something more in this package

[wicked river]

same, I am struggeling to find actuall examples

[rigid island]

https://assetstore.unity.com/packages/templates/tutorials/muse-behavior-tutorial-project-269570

[wicked river]

I have this.

[rigid island]

I can look into it and study it up I'd be interested in exploring this example maybe video it

I gotta run out for a few hours so can't look till later

[wicked river]

THis is where I got the idea

from that example

the animatorObject.value.GetComponent

[rigid island]

are they seriously using .Find ?

🙄

[wicked river]

Yup

[rigid island]

you watched the video as well right?

https://youtu.be/BeqU-njZesY

[wicked river]

Yup They don't use external scripts

so I guess I am stuck with find

will try it out and see if there are better ways later

[heady iris]

the future is here!!

[rigid island]

I mean it works fine, just find it funny that unity does the things they recommend others not to do

I am using Physics.OvelapBoxNonAlloc to detect something while trying to avoid the garbage allocation.

private static Collider[] hitResultsBuffer = new Collider[1];
Physics.OverlapBoxNonAlloc(position, size, hitResultsBuffer, Quaternion.identity, LayerMask.GetMask("Enemy"))

But the second line do allocates a garbage! Is it normal? Allocation is 40B but it can stack up so i cant dismiss that. Am i using that method wrong?

It seems something wrong in native side

[leaden ice]

It will be the GetMask call allocating it

GetMask takes a variable argument list

C# handles that by creating an array

cache your layermask

[orchid abyss]

what's wrong?

[vagrant blade]

You have an interactor component in your scene that doesn't have a point assigned.

[orchid abyss]

it does tho

[naive swallow]

The variabe _interactionpoint of interactor has not been assigned. You probably need to assign the _interactionpointvariable of the interactor script in the inspector

[vagrant blade]

The one you showed does. Doesn't prove there isn't one out there that doesn't.

[orchid abyss]

wow that's helpful

[quaint rock]

you have more then 1 of these in your game

[naive swallow]

Indeed! It tells you exactly what the problem is and where to look!

[quaint rock]

or something destroyed the object its referencing

[orchid abyss]

that's the only thing that has it

[vagrant blade]

How did you verify that to be true?

[naive swallow]

Screenshot your unity window with t: interactor in the hierarchy search window, after the game begins and the error appears

[orchid abyss]

oh woops the camera also has the interactor

dk why

[naive swallow]

because you put it there

[orchid abyss]

ooh its from a diff tutorial

[thorny osprey]

So unity has UnityEvents which work really nicely, and can be invoked, and from the inspector work in an awesome way where you can just load up any number of functions an event

I'm wondering if it is possible to do a similar sort of thing in the inspector but with a variable rather than a function

To maybe help make it more clear what I'm trying to do, is something like this image below, but instead of the "Value" being a bool check mark, it is a selector where I can select any of the public variables from the above script. is anything like this possible?

like see how an event works with functions and a list, i really would like to be able to do a similar thing with variables

[astral nexus]

how to handle persistent ID for prefabs between scene loads and maybe game sessions? I can't figure it out for non very bad or sloppy way of achieving it

[naive swallow]

Events work with properties as well. Just turn your variables into properties and you can set them via UnityEvent

[thorny osprey]

what do you mean by properties? like class variables? do you know of any examples?

[naive swallow]

https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/properties

[soft shard]

What is it your trying to do, where you need to persist a prefab across game sessions? For scenes, you could probably put the instance in DDOL so it survives scene loads, or store them in a list inside a scriptable object or singleton, and pass the index to the next scene so spawn a new prefab of the same type

[thorny osprey]

Intersting... I'm not entirely sure that helps my case as UnityEvent was really more of an example than what I need

Basically what I'm trying to do is have a list, like a UnityEvent, where I can select variables/properties on a script and their state. I'll call this list like "requirements"

Then, I need to go through the "requirements" and see if every variable in the list meets the chosen state... I assume that a property in an event is calling set and not get, right?

I basically need it like this, but instead of setting Test to false, I just use get and return true or false if it is equal to what I have here (unchecked, so false)

Idk if that makes any sense lol

[honest kestrel]

is there a way to export the way the bones in an animation move mathematically?

ie what transformations were applied to the bone

[astral nexus]

I'm bad at explaining (and made a mistake when I typed my last message, I meant only between scene loads, not gamesessions, lol)
I want to store a UI data between scenes separetely from my UI elements, so I can just put my old state into new instanced prefabs of my UI views and it's ready to go
I can't just use type as key, because view elements can be multiple of the same type but different in data values (like labels and buttons)
for data store I've used scriptable objects, yes, but I dunno what to do with loading UI elements of the same type and different data associated with them, so I was thinking about GUID or something similiar, but I can't figure it out how to setup it's generation properly

[unreal ingot]

If Im making something like a conveyor belt to move an object that is touching it, is it best to

1. add a small amount to the position every fixed amount of time
2. set the velocity of the object to a certain amount
3. add a force to the object

[orchid abyss]

i dont get it

[quartz folio]

Your method is not declaring a body, you have a semicolon here.
The next error is probably telling you that the { is unexpected.

[orchid abyss]

ah

[soft shard]

Ah I see, static variables exist in memory so their data doesnt rely on the state of scenes, and ScriptableObjects exist as assets in the project, which also doesnt rely on the state of scenes, however you can also create ScriptableObjects at runtime as instances, which are not files yet, and exist in memory, which also means they can persist across scenes, so any of those 3 options could help if im understanding what your trying to do correctly - with a GUID, I think that might be a bit overkill, though youd want to make sure you only register the GUID once for that object when it is initially created, and then store that GUID in some kind of static list or file so it exists in memory or accessible through System.IO, then you can read that file on the next scene or access the static list and compare the GUIDs in the list to your prefabs matching the same GUID, though that still uses static where the former may be a little less involved to implement imo

[thorny osprey]

Ok I have anotehr question similar to earlier lol... is it possible to
a) have delegates show in the inspector, or
b) have unity events return a value other than void

[quaint rock]

unity events can pass data

you can have a UnityEvent<int> for example, and when you invoke it can pass it int into invoke and all subscribers will get it

[thorny osprey]

I'm thinking more like, a UnityEvent which has X functions loaded in it on invoke, then if all of X functions return true, the event returns true, otherwise the event returns false

I know thats a little weird, which is kind of why I thought delegates would be my solution, but those don't work in the inspector AFAIK

[quaint rock]

yeah not something you could do in the inspector directly

[thorny osprey]

i kind of need it to be for what I'm doing lol, otherwise ill have to hard code so much stuff... do you know of any alternatives to what I'm thinking? i just need a way to have the functions, or even variables, that the event/function is checking to be determined in the inspector

[quaint rock]

interfaces, or abstract classes

reference objects that have a common interface method to call for it

[dusk apex]

Reference the component and implement how they'd interact through script.

[quaint rock]

really virtual or abstract methods on a common type would do it

since they you have your list of them, and can loop and get the return from each one when calling the method

[thorny osprey]

and that can be assigned via the inspector?

[quaint rock]

yeah since you are just dragging in a regular component reference

they all just share a common base type that has a abstract or virtual method

[thorny osprey]

so if im understading this right, i do a virtual function, say CheckRequirements() and then use an interface to add the inspector functionality? sorry if im slow here ive never used interfaces before lol

[quaint rock]

well due to a quirk of unity you cant use a interface for the part in the inspector

so would give all the things that should have CheckRequirements a common base type

that has the virtual method CheckRequirements they can override

[thorny osprey]

The things running CheckRequirements would all be on the same script, but the functions to be loaded (to be checked) wouldnt necessarily

well

[quaint rock]

yeah that is hte idea

[thorny osprey]

alright then I guess im just not understanding which part enables the inspector aspect lol

[quaint rock]

the thing calling CheckRequirements would have a list of BaseRequirement on the inspector

then anything extending BaseRequirement can be put in that list

and each of those things can override and define there own CheckRequirements methods

[thorny osprey]

okay im understanding what you mean now, but I'm not sure thatll solve my problem either cause the classes i'm looking to get the data from wouldnt be extending the one with CheckRequirements, they are MonoBehavior

[cosmic rain]

Make them extend the CheckRequirements...🤷‍♂️

[quaint rock]

https://gdl.space/pekesucixe.cs

[thorny osprey]

ok its gonna take me like an hour to wrap my head around this but i think this might be what i need

thank you

[quaint rock]

yeah not fully sure what you are trying to do, but that is one way of doing it

instead of needing to manually drag to the list, also would be doable to just have each requirement as a component you add to the same object then on Awake you get all of them at once save to a list then use that to evaulate things later

[thorny osprey]

so in your example, you are putting SomeReq into the list of BaseReqs right?

What if I needed to have a list of BaseReqs, then something reference BaseReqs, then my SomeReqs reference that something

So like here is my kind of layout

I have an Interactable (contains CheckRequirements())
then I have BaseReq
then Bucket : BaseReq, this has property isFull
then I have a Bucket_IsFull : Bucket, overrides CheckReq to return the isFull propetty
but I cannot put the Bucket_IsFull script into the list of BaseReqs

[quaint rock]

SomeReq can is stored in list of BaseReqs

anything virtual/abstract in BaseReqs can be overridden in the stuff extending it

and when you call it, you will get the overriden version

[thorny osprey]

and what about a double dependency

like for me it basically goes BaseReq<--Bucket<--SomeReq

i can't just go from BaseReq to SomeReq unfortunately cause I have properties in other scripts I need to reference, like the isFull in my bucket example

[quaint rock]

thought you would just check that in the overriden method to decide if it returns true or not

like the things extending BaseReq can be what ever you want, they just must implement its abstract methods

and you can have multiple thigns in the inheritance chain though it would recommend not making it long and complicated

[rancid frost]

does anyone know why my events either lose reference or get unsubscribed after being serialized or say after you make changes to script and unity reloads

[wicked scroll]

are you referencing scene objects from non-scene objecst? those references cannot persist beyond playmode

anything you reference in a prefab much be within that prefab, another prefab, or an SO

[rancid frost]

No, I have a class that contains visual data (color, texture etc) when I change the data of said class (change color for example) an event if fired, detailing any meshes that uses that class data to update

the problem is that when I make changes to the code, that event is unsubscribed and I have to resubsribe it

[wicked scroll]

yeah unity isn't going to serialize that (unless you make it a unityevent?) event

there's probably a better way to do what you're trying to accomplish that doesn't rely on that

[rancid frost]

im open to suggestions

I could use OnValidate method but that is messy

[wicked scroll]

does this need to happen at editor time? I guess I would just populate the meshes with whatever they need at runtime

if there are a lot of potential options they could ahve

[rancid frost]

both

Im making something similar to tilemaps

user should be able to make map with editor and during runtime

[wicked scroll]

well i would probably look into how #↕️┃editor-extensions work, since that's basically what you want here

then you can couple it to unity instead of to your scene and scene objects so that your events or whatever you're doing persist

[rancid frost]

ok, Will do

[quaint rock]

it will be hard to do it via events, since that will get nuked on all domain reloads

might have to be a editor scripting type thing where it queries for all the things it applies to and applies it

[rancid frost]

huh

what if i check for a change in the update method?

[jagged snow]

spawnInfos[i].OnRemove += () => { Destroy(gameObject); };
is there a reason why i cant assign this action?
: Cannot modify the return value of 'List<SpawnInfo>.this[int]' because it is not a variable

hmm looks like it worked after i made one inside the for int loop

[fervent furnace]

indexer is method, so

spawnInfos.Get(i).OnRemove+=

also notice delegate is immutable as string

[jagged snow]

it's a struct so its not possible

            spawnInfo.OnRemove += () => { Destroy(gameObject); };```

This worked

[lyric belfry]

I am trying to use Array.IndexOf(instantiatedGameObject) to get the index of itbut the array itself was made inside the editor with prefabs.

IndexOf() is returning me -1 which means it can't find the gameObject in the array. This seems to be because the reference to the instantiated gameObect is not the same as the prefab itself inside the array. Not sure what to do

The picture shows the current values of things and the lists I am accessing

The gameObject is BallistaTowerLv1(Clone) and the list has the original BallistaTowerLv1 prefab.

My main question: How can I get the index of the BallistaTowerLv1(Clone)

[quartz folio]

They are not related. Maintain some sort of data that would indicate what it was spawned from, an ID on both perhaps.

[lyric belfry]

I see. Was trying to get around that but I guess I will look more into this approach

[deft dagger]

hey, i have a place in my multiplayer game where when you go there another scene loads additively normally when there are more than 1 player and someone goes there the new scene only loads for the player that entered that area.
but if the host enters the area before the others join. when they join the scene loads for everyone that joins after the host entered the area.
how do i fix that ?

didnt even change the code, just opened up unity and so many errors

[knotty sun]

you probably have a duplicate script

[tawdry lake]

any clue how i can fix that glitchy transition

[tawdry jasper]

For a simple interaction/melee system would you recommend putting a collider on the swinging weapon/item, or have a box collider / physics cast in front of the character? I'm using the latter now, but my code is becoming quite messy. I think both solutions will end up with situations where it looks like you should have hit something but you didn't or you did but it looks like it shouldn't so I'm mostly concerned with minimizing code and making use of standard unity features.

[tawdry jasper]

It does look "of" but it's hard to tell whats happenning (to me), open up your character animator state machine, put in a scaled time=0.2 in editor/time settings and observe what states and states transitions are happening. This helped me debug stuff in the past. Maybe you'll see what's wrong (like a state is playing twice, or something like that)

I'm making a drawer for a serializable class, and running into some issues.
I've got the serialized property for the class, and in it is a reference to a scriptable object.
I'm trying to read a boolean off of that scriptable object, but doing this:

var statBlueprint = property.FindPropertyRelative("_statBlueprint");
var canDamage = statBlueprint.FindPropertyRelative("_canDamage");

Gives me null for canDamage. _canDamage does exist as a private serialized bool in the StatBlueprint class. Am I missing some in-between step to retrieve it?

statBlueprint is not null, so it's not that

[deft timber]

how did you make sure

its not null

Ah, wait, found what I actually needed to do:
StatBlueprint statBlueprint = property.FindPropertyRelative("_statBlueprint").objectReferenceValue as StatBlueprint;
And now I can read all the fields from the statblueprint in the class

oh huh interesting

there seems to be a lot of multithreading stuff I do not understand

[chrome berry]

It's definitely an advanced topic when it comes to Unity games, most will never use them

[fervent furnace]

shorthand for creating critical section

[chrome berry]

I was getting that error with my singleton too, except it wasn't listing ANY object at all. Just a blank line after The following scene GameObjects were found: which was not helpful

Though it looks like I fixed it at some point, as I'm not getting the issue anymore

[quaint rock]

better to leave alone till much further along, concurrency can cause lots of very strange bugs, and most unity code must run on the main thread anyways since very little of it is threadsafe

[clever lagoon]

Everytime you even LOOK at Singleton<T>.instance it will create a new one, if one doesn't exist. I'd guess that something is doing that after you start closing the scene- it might be in OnDestroy, or it might be a response to a timer/event. IF this only occurs when the game is closing/quitting you can monitor this event, set a flag, and NOT create a new singleton instance once triggered. https://docs.unity3d.com/ScriptReference/Application-quitting.html

Hello I have run into a problem while working on my fishing top down game: I have a script for random generating prefabs of gameobjects of trees, rocks and mainly LAKES, where I have attached a script for triggering my fishing minigame (image). This script contains references to other game objects (interact window, timer etc.). Is there a way on how to "instantiate" (dont know how to use this word properly :D, so basically just fill) those references everytime the prefab of each lake spawns? I would appreciate any help.

[dense rock]

exactly, sry for the late answer

[dense rock]

lucky you, glad you got it fixed!

[dense rock]

sry but what do you mean by setting a flag? And how do I monitor that? I searched for instance calls in the project but there seem to be non in ondestroy etc. Shall I just copy the code from the provided link?

[trim schooner]

I always just ignore them

[dense rock]

true but I observed a couple of times where it then did not instantiate the go correctly on the next start. There then was an object with the same name without any components

that error has since been gone tho

[glacial snow]

how difficult is implementing steering behaviours for AI pathfinding
like this where you have different weights for which direction the AI might want to go

[clever lagoon]

by setting a f;lag I mean, create a static bool member say isQuitting in your singleton- default value is false. You can add a listener to that event I posted, such that when triggered, it will set that bool to true. Lastly, inside your instance getter use an IF to check that bool, and if true, abort creation.

NOTE: if this problem is occuring whe you say.. change scenes- my suggestion wont help. only good for quitting.

kedshfeiskd you game looks so gooood
mine doesn't

Here's mine, if you need one for comparison

[dense rock]

thats a good one

[dense rock]

the problem happens when quitting the application and thanks for the help, I'll try refacturing the code :)

Hi. I have created my first unity protect. I don't have lot of knowledge in unity but I know C#. How can I split the camera into two parts and assign a different background color to each part.

[chrome berry]

There's probably another way to do what you're trying to do. Can you provide a visual of what you want it to look like?

[marble mauve]

I have set the backgroun color of the camera to blue but I want to split the camera horizontally into two parts each part with his own custom bg

I don't know if I have to create and script that implements the feature or in the other hand there is a way to do that without using c#

[chrome berry]

Why? Is each section for a different player? Or it's a different play space?

[marble mauve]

Its for a single player but I want to set it like that as there are like two teams blue and red but the UI will be only used by one player.

[lean sail]

The hardest part is actually getting the data for what is a valid path. You could just use unitys navmesh for this. The pathfinding algorithms are already invented, you just need to choose one.
If you're talking about doing this solely based on raycast (which is what your image looks like) then that isnt pathfinding because it's just going in the direction of least resistance and hoping there isnt some giant wall it isnt aware of

[chrome berry]

You're far better off just putting a flat plane there with the right colors. Trying to split this up into 2 cameras is going to be far too much of a headache

Or a large sprite that's just a single colour

[marble mauve]

and where I find a flat plane. Sorry but as I said I don't know so much about unity. I am testing and then I will start reading the guide and docs. It could be a canvas in component > layout ?

[chrome berry]

Is this a 3D game or a 2D game?

[marble mauve]

2d

[chrome berry]

Create a square PNG in the art package of your choice (i.e. GIMP) of the right colour. Dump that into your scene as a sprite and stretch it to the right size as your background.

[marble mauve]

so I have to create a PNG which will be my background? and then add it as an script an resize it with the dimensions of the camera?

[chrome berry]

Do you want it to move around with your camera? Or is your camera just going to be locked in position the whole time?

[terse surge]

there was a thing idk whats its called but like certain type of code. My teacher suggested for us to look into it as it would help us with a problem someone had, where basically they wanted to close whatever UI menu was open if another one gets opened, anyone knows what im talking about here?

[marble mauve]

It's a fixed view where the user only have to click buttons etc.. so there is nothing that has to be moved

[chrome berry]

Then you're just placing the sprite in the scene and adjusting the transform on the object to position and scale it. No scripting involved.
The scene is the level, you're placing an object in the level to act as your background that the camera is looking at

Then whatever other sprites you have will just be above that background sprite

[marble mauve]

Okey. Thanks.

[chrome berry]

Or, if you're doing everything in UI only, with no sprites, then you'd place Images in your Canvas as the background, and stretch those to fill the canvas and colour them

I want to learn how to use unity and code different things but I’m unsure how to learn the code that is used for making games

[quartz folio]

!learn

I would like to add two sprites but they will be only static so I think the static background is suitable

[sacred sinew]

I have a game object that appear on the "scene" but not in the "game" tab, it uses a code to move with the mouse but does not show on the game render, do someone know why ?

[hexed pecan]

It's probably just too close to the camera

Is it a 2D game? If yes, just set worldPos.z to zero

IIRC ScreenToWorldPoint gives you a position on the camera's near clip plane

[sacred sinew]

ok thanks

it worked thx

[dark kindle]

what would be a good workaround to this issue, "size of the vertical scrollbar reverts back to 0.61 when trying to adjust the value slider"

I am dealing with this problem where i have multipple buttons

inside scroll view and i cannot see all of them

[heady iris]

that issue is about the scrollbar itself

it sounds like your problem is about the contents of the scroll rect

[dark kindle]

yes, and i ask here because maybe there is a programmatic solusion

[heady iris]

Did you use the "Scroll View" preset?

[dark kindle]

let me confirm

yes

[heady iris]

put a ContentSizeFitter onto the "Content" object

Also put a VerticalLayoutGroup onto the "Content" object. Check both "Control child size" boxes and uncheck "force expand"

You will now need to put a layout group onto every object that has children.

• Content <-- ContentSizeFitter, VerticalLayoutGroup
  • ButtonParent <-- VerticalLayoutGroup
    • Text
  • ButtParent <-- VerticalLayoutGroup
    • Image <-- VerticalLayoutGroup
      • Text

e.g.

All of them should be set to control child size.

This is a #📲┃ui-ux problem, so if you have further questions, ask them in there

(i'm getting back to work and won't be around for a bit)

[dark kindle]

ok appologies, and thank

[woven horizon]

I am trying to make the bullet trail for the weapon disappear after the certain time has passed

the idea is to simulate what would be a gameobject projectile while I am just using raycasts

I am trying multiple approachs but cant seem to find one that works

[latent latch]

why dont you just use a linerenderer

[woven horizon]

it is a linerenderer

it is a gameobject with a line renderer

and nothing else

[latent latch]

so, what's the exact problem? You can set the time which each segment expires.

[woven horizon]

wait you can do that

omg

[latent latch]

there's a curve right on it

go play around with it in the inspector

[woven horizon]

can I dynamically adjust it tho?

[latent latch]

uh, it may use keypoints

[woven horizon]

cause the problem I have is that I want it to disappear depending on how long it would have taken a gameobject to hit whatever was hit

and then run all the logic after that time has passed

or should I instead have no bullet trail and just show a muzzle flash and an effect where the bullet hit?

I think that's a better idea and I am just making it harder for myself

[latent latch]

https://docs.unity3d.com/Manual/class-TrailRenderer.html
Sorry, I meant trail render, not line

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

Has a time property

[woven horizon]

oh ok

thats very helpful

thanks

[marble mauve]

I am doing a canvas but I can't reduce the width or the height and I can't move it through the screen

[soft shard]

Not sure if there is a particular word for it, sounds like your describing just updating a reference, or possibly a event bus could also handle something like that, or possibly a state machine, though those approaches are usually a bit more involved than your description, it sounds like your more-or-less asking about something like this?

public class SomeUI : Mono
{
GameObject opened; //keep a reference to what is opened

public void OpenAnother(GameObject ui)
{
//should probably do a null-check incase nothing is opened
opened?.SetActive(false); //hide the previous window
opened = ui;
opened.SetActive(true); //show another window
}
}

In that example, something would call OpenAnother passing the UI object that should be displayed, causing the current one to close, get updated and show the one passed instead, though im not 100% certain if this is what you were trying to describe

[soft shard]

The canvas has 3 modes, by default it is locked to the screen space overlay, meaning it will render above everything and cannot be adjusted through the transform, instead it uses a Canvas Scaler to adjust itself based on the screen its displayed on: https://docs.unity3d.com/Packages/com.unity.ugui@1.0/manual/UICanvas.html

If you want to be able to change the size of the canvas itself, you may want to try one of the other 2 modes, however that also means it wont properly overlay and fit the screen, so its good for in-world UI but not UI you might want always on screen

[marble mauve]

I'm trying to resize it because I want it to fit with the camera

[terse surge]

alr thanks

[marble mauve]

Also I'm trying to change the button text of a button in that canvas but there is nothing in the inspector that might be consider to change the button's text

[soft shard]

Ah, instead you might want to try the Canvas Scaler instead: https://docs.unity3d.com/Packages/com.unity.ugui@1.0/manual/script-CanvasScaler.html - there is a mode to have the canvas match the width or height (or attempt both), based on the screen resolution, which the Game window can preview for you (normally the area that says "Free Aspect" can be changed to specific resolutions)

[mighty flax]

Apparently my question should be asked here instead of #💻┃code-beginner -

Hi everyone! I need help with a terrain generation script that I tried modifying to work multi-threaded using Burst and NativeArrays/Lists. The game I'm working on is meant to feature a minecraft-esque terrain and I had it working single-threaded and using a LOD system that just lowers the resolution of the voxels the further away you are from them on orders of magnitutes of 2. This was all working on a single thread but was obviously very laggy when you moved between chunks because all the processing was happening on the main thread. I've programmed what I believe should be the multi-threaded equivalent of the previous code I had written but now nothing renders and additionally I've got an error along the lines of "Leak Detected: Persistent Allocates 1 individual allocations." which I'm not entirely sure how to fix because I need this array to stay persistent

[soft shard]

The text would be a child of the button object, youd have to select that child object to change the text through the inspector (assuming you dont want to do this at runtime/through script)

[marble mauve]

okey thanks I'll try it

[marble mauve]

ah I didn't see it in the hierarchy

[sinful mortar]

is there a way to tell which monobehavior this was? as in a string name or something

[woven horizon]

hey, quick question, can this be used for 2d games? they seem designed mostly for 3d

[rigid island]

prob not , seems it doesn't have the .meta

[sinful mortar]

I don't think that's the case because this seems to happen when scripts are deleted after they've been attached no?

I guess just gotta dig into the yaml

[latent latch]

I don't think there's a 2D variation, but I don't see why it wouldn't work

[woven horizon]

ok, gonna give it a shot

[hexed pecan]

That's probably your best bet

[rigid island]

well yeah thats if you delete the file without deleting it from the object you're gonna see that

[sinful mortar]

yeah exactly, question was figuring out which file that was, but looks like I just have to redo this because it's related to UI Toolkit being updated between 2020 and 2021

[hexed pecan]

Did the meta file tell you what component used to be there?

[sinful mortar]

oh hmm I only checked the .prefab yaml file but that only had guids

so I ended up removing them and yolo guessing based on the script and kinda got it working 😅

[nimble cairn]

Thoughts:

When a player turns sound effects volume to 0 it is inefficient to keep audio sources enabled in the scene.

[rigid island]

have you actually profiled to notice any benefits?

[nimble cairn]

This is not an issue I am currently facing. I just wanted to open a dialogue.

[rigid island]

I get that, and asked if it was speculative or legit

[nimble cairn]

Well, I am speculating that it would be more efficient to disable all sound effect audiosources.

Someone else might subscribe to another school of thought. I can already hear someone saying it's a micro optimization.

[long ridge]

How do you update navmeshsurface via script?

[rigid island]

reference it

call bake
