I am a little annoyed that I have two separate types for global settings and per-object configurations. I bet I could condense that down...

rich adder
#

where is the code question ?

#

then why are you posting here

delicate portal
#

I have a question related to Unity's netcode for gameobjects. I implemented a simple multiplayer host-client system but whenever I click on host it works perfectly fine until I make another instance as a client. Then the host's camera swithces to the client's, why is that? It has to do with camera ownership or something like that right?
This is my cameraHandler script:

I thought I'd get quicker help here

#

post in the proper channel

timber tide
#

if you have to ask that question then you didnt read the docs

#

How could I spawn a sphere at a random point on the map?

delicate portal
#

I kinda lean towards having only one camera and let it follow the local player rether than having a two cameras in the scene

yeah, you get nonsense units if you try to use deltaTime there

oh god i got punked too notlikethis

in my defense, I have a cold

lunar grove
#

can we change character controller radius and height programatically in code?

swift crag
#

One thing to keep in mind: after changing the height, you'll also want to change the center.

#

you usually make the center half of your height off the ground

lunar grove
#

oh okay but all my trying to do is change the character controller's height when I press or hold a key

#

bu thtanks for the help though

rich adder
#

not code question

When I work on a multiplayer game should i first make the game as if it was a singleplayer game, creating the player, map and anything else that's relevant to the gameplay and then port it into multiplayer or port the parts of the game in multiplayer as i make them?

rich adder
#

man if you need to ask this, frankly you're not ready for multiplayer

thorny orchid
#

Well you gotta start somewhere right?

rich adder
#

starting would be not diving head first in multiplayer

thorny orchid
#

How do I tackle learning multiplayer if i don't dive into it, like eventually im gonna have to learn it

swift crag
#

you will want to start with tutorials or pre-built example projects

#

Multiplayer breaks a lot of rules

rich adder
#

not like tutorial games like pong or something

#

when you made all the systems yourself , then you're probably ready to dip toes

#

imagine having to sync all those same systems across different builds

swift crag
#

the big hurdle with multiplayer is that you can no longer know the whole state of the game, and that many things are no longer "instant"

thorny orchid
#

No I've never released any games yet, i had one tutorial game that being flappy bird, and then i decided to try and make pong without following any tutorials, it didnt take me that long so i decided to add like powerups and also advanced settings that let you change some variables from ingame, i started working on a breakout game but I got bored of it that's why I wanted to learn multiplayer

rich adder
thorny orchid
#

Cause like with multiplayer I can show it and play with friends once its done so I'm more motivated to finish it

rich adder
#

maybe the idea of that is exciting but once you go deep into it you realize its the same stuff you were doing for say Breakout but now more complex and more problematic

#

its not a discouragement post, you can do what you want but just saying what to expect since multiplayer is somehow seen as "Easy"

thorny orchid
#

What would you suggest is best for me to do now maybe work on another single player game before diving on more difficult stuff?

rich adder
#

maybe trying to aim for an actual finished release, even if no one plays it. You now have a finished product on your belt

#

this forces you to learn things like Menus, Settings, Data persistance

#

all very important topics

thorny orchid
#

One last thing, how did you learn how to make multiplayer games?

rich adder
#

I just worked on smaller projects that sync max of 4 people , something like simple Prop hunt games and other spin offs of gmod type mini games

#

by doing lots of singleplayer projects

#

all the systems are the same but now you have to sync that across different versions of the game which is what makes multiplayer complex. Keeping that data in sync and not compromised

#

I'm not at all close to good

#

mutliplayer is too hard to do alone anyway

thats what mixers are

short hazel
#

Routes audio through channels that can be independently configured

stuck palm
#

cus i had this really unnecessary audio manager class

#

if i can just use an audio mixer that would be a lot easier

short hazel
#

You'll have to configure all the audio sources to use the new mixer, but yes it simplifies stuff, and is controllable by code with parameters (like animators or shaders)

stuck palm
#

Perfect, thank you

that will be a lot easier

sage mirage
#

Hey, guys! I have a question. How to stop if I want to the speed of my GameObjects?

#

For example, if my object is moving and I want to prevent that from moving

polar acorn
wintry quarry
#

objects don't move on their own

#

unless it has a Rigidbody.

sage mirage
#

I mean I can't just set the timescale to 0 because it freezes the game what I want is to just set it's speed to 0 or something and yes it has rigid

wintry quarry
#

Make the body kinematic

#

or just set its velocity to 0

sage mirage
#

Oh, ok thanks!

#

Yeah, I forgot about velocity.

#

im using a line renderer, how can i spawn like a circle where the line intersects with the floor?

image.png
swift crag
#

You will need to handle that separately.

frosty hound
#

Put a plane with a circle texture at that point?

#

Or use an asset like Shapes to generate it

rich adder
#

prob need some type of raycast from the points closer to the end

swift crag
#

Finding that point will require a little bit of legwork.

#

yeah, short raycasts from point to point would reveal where it hits the ground

stuck palm
swift crag
#

As long as the points have consistent spacing, sure

#

Otherwise you might miss the ground

stuck palm
#

they should, yes

zealous oxide
#

hey friends, whats the suggested way of moving a game object from one scene to another? its something i've not done yet and i want to know whats the best practise. SceneManager.MoveGameObjectToScene or using Object.DontDestroyOnLoad ? thanks

swift crag
#

of course, a raycast would also tell you exactly where you hit the ground

#

so the circle could be placed more accurately

swift crag
#

If that's the case, then that sounds like the best option

#

DontDestroyOnLoad moves you into a special scene that's never unloaded

#

so you still wouldn't be in a second scene

#

you'd just not be in the first scene!

zealous oxide
# swift crag You'd need to have multiple scenes loaded simultaneously to use MoveGameObjectTo...

wicked, thanks. im aware the second scene would need to be loaded. I've found this https://stackoverflow.com/a/45802196 but "sceneAsync" seems to be psuedo code in the example as in my ide its highlighted red. im guessing this is what should have been written in? SceneManager.LoadSceneAsync

Stack Overflow
Move/Transfer GameObject to another scene

We tryed different ways to move UI-object to another scene, but we failed. Over object is in Canvas.

Method 1: we used LoadLevelAdditive, but there moved all objects from first scene without over ...

swift crag
#

sceneAsync is declared up top

zealous oxide
#

my bad

#

gonna give this a try, thankyou

stuck palm
swift crag
#

that does not consistently space your points

#

they're spaced consistently in time, sure

#

but the thing is going to move faster and faster over time

#

Go with raycasts between each pair of points.

stuck palm
#

like a raycast downwards?

swift crag
#

no, a raycast from point X to point X + 1

stuck palm
#

oh i see

#

yeah so i'll have to store the previous one and the current one i guess right

swift crag
#

You could raycast after every 5th point or something if it turns out to be a performance issue

#

you probably don't need to raycast EVERY pair of points

#

but you do want lots of points for a smooth curve

stuck palm
#

i'll just try and see what works, thank you

zealous oxide
rich adder
eternal falconBOT
short hazel
#

That's a lot of code for something that would be identical to using DontDestroyOnLoad() on the player

#

And no, the old scene stays since LoadSceneMode.Additive is specified

Hello. I am using nav mesh and nav agent + 3rd person view and mouse input + raycast to determine where the hero has to go, and it's working just how it is intended. But... that raycast seems to ignore te UI elements and is sending the hero to run when I am trying to interact with UI elements. In this case Inventory and Equipment windows. Is there a way to prevent this? And I think I still want my hero to be able to move when UI is open, so disabling the nav agent / movement script while UI is shown is not an option. Especially because there are parts of UI that are always shown.

Heya! I'm trying to use an optional variable for a color that will either be passed down or just insert a defaultcolor, however I didnt manage to get it to work with
Color color = defaultColor where color is the variable i want to use in the method and defaultColor is the default color declared further up in the script.
It tells me that Default parameter value for 'color' must be a compile-time constant

short hazel
#

Consider making a method overload, where it executes the other method with your color

void Method() => Method(Color.red); // whatever default color
void Method(Color col) { /* implementation... */ }

i'm still stuck with my moving gameobject between scenes problem. i've now used the code off the unity documentation (its simpler than the stackoverflow example) and it doesnt work as intended. I have to hit the key to start the coroutine twice and then it moves the game object into the new scene but it only unloads the old game scene the second/subsequent times I hit it. the coroutine stops just shy of moving the gameobject. it seems to be trying to be moving the gameobject before the scene is loaded if i'm reading it right? https://hastebin.com/share/loxinejudi.csharp advice would be welcome

# rotund hull alright thanks

Do note that collision events are bubbled upwards the hierarchy to the Rigidbody. So if you have a Rigidbody on an object, and that has multiple children with colliders on it, then the object with the rigidbody will be the one catching the collision messages

#

by adding a quad ?

rocky canyon
rocky canyon
#

a quad, a plane, a sprite.. but it would have to be a World Space Canvas

#

could probably parent it to the camera too.. so u could just have to fill the camera's frustrum.. and it would follow the camera around whereever it looked.. so it would always be in the background

queen adder
#

ok yes i get that part

#

let me show you what i got rn

#

when i make it to world space canvas its no longer on the screen

rocky canyon
#

you have to position it

#

its not gonna be exactly where u want it..

#
  • click the gameobject
  • hover over the scene view
  • press F to focus on it
swift crag
#

A world space canvas has a literal position in the world. It's not going to be automatically drawn onto your screen or positioned in front of the camera

queen adder
#

so it will have to be positioned into camera field of view manually

rocky canyon
#

yes

queen adder
#

if the camera moves it will all break inni

rocky canyon
#

it doesnt work the same as a normal canvas

#

a normal one is drawn Over the screen and can just scale to it

#

a world space doesn't do any of that

queen adder

okok

#

would the buttons still work

yes, as long as its not covered up you can click it just like a normal canvas

#

If there was an error, you'd see a popup or something

no, red lines show up when i get an error

ohh

#

it might just be red normally

#

i don't think it's a problem (and it's certainly not indicating you have a compile error)

stable ore
#

its not

stable ore
#

and idk why

swift crag
#

That has nothing to do with your code editor

#

That's because you have Error Pause enabled in the console

#

Ask about your actual problems, not about your attempted solution to those problems.

# zealous oxide i'm still stuck with my moving gameobject between scenes problem. i've now used ...

https://hastebin.com/share/hivujobipa.rust apologies for the bump but i'm still hoping someone has a suggestion of whats going wrong here? this is my first time trying to move an object between scenes. in the debug log I can see the scene is loaded @ 100% but the subsequent debug line says the Destination Scene is not valid. I can see in the build manager there are only two scenes, the one start scene and the second scene, that i'm trying to load the game object into it

but score not changing idk how to fix

# oak fulcrum

you see where u have Text scoreText thats ur variable. u can change it by calling scoreText.text =

#

to make a number into a string (thats what text displays) you use the ToString() method..

# 
            // Update the text with the current score
            scoreText.text = "Score: " + score.ToString();```
#

score would be ur integer

AudioCont.clip = null;

this looks fine 🤔

since ur learning u'll be fixing problems for a while lol

rocky canyon
#

this is the score right?

stable ore
#

😁 🙂

rocky canyon
#

wouldnt it be v.ToString();

#

ur passing in the score to that function with the v variable

stable ore
rocky canyon
oak fulcrum
#

so should i replace the int v with v.ToString();

rocky canyon
#

u can also call OneShots() it will play a audioclip u tell it to.. w/o having to chnage the clip in and out

# 
        {
            // Play the audio clip once
            audioSource.PlayOneShot(myAudioClip);
        }```
smoky niche
#

Hey, I have a small performance related question.
Is it performce-heavier to use a reference to a float value from another script rather than using a float value from the same script?

rocky canyon
#

v is a wierd variable name.. but yes

polar acorn
#

If you did it four billion times it'd take one second

rocky canyon
#

you may need to pass in the current score as well.. so u can add it before u change it into a string..

smoky niche
oak fulcrum
rocky canyon
# 
public void UpdateScore(int currentScore, int scoreToAdd)
{
    int newScore = currentScore + scoreToAdd;
    scoreText.text = newScore.ToString();
    Debug.Log("Changed The Score: " + newScore.ToString());
}```
#

this would make more sense to me.. so u can add the score to the old score.. without having to worry about trying to convert the string back into a number.. then adding it.. and then converting it back to a string

oak fulcrum
#

it still doesnt work

stuck palm
#

@swift crag got it to work kinda, they seem kinda off though,this is the code i wrote, any ideas why it might not work?

image.png image.png
rocky canyon
#

did you assign the text variable in the inspector?

#

did u get errors? can you get errors?

swift crag
oak fulcrum
#

i didnt get any errors

swift crag
#

you need to raycast from point i-1 to point i

oak fulcrum
stuck palm
#

wait

swift crag
#

remember what your last point was and use that instead of origin

#

(and skip that for the first iteration)

#

actually, as long as you remember where you started from before you start the loop, you don't have to skip a step

rocky canyon
#

easy enough.. i'll share the script if you need it.. but its basically what you have already

oak fulcrum
#

send sir

rocky canyon
oak fulcrum
#

hold on wait

stuck palm
rocky canyon
#

its a Public void AddScore so as long as u reference this script you can just call that function from anywhere

#

also its using TextMeshPro.. instead of ur regular text.. cuz ill go ahead and tell you.. Unity's regular text sucks

#

TMPro is much better

oak fulcrum
#

this is broken rn

image.png
rocky canyon
#

well wheres the underline?

#

what do you think it means?

oak fulcrum
#

it doesnt call the right thing?

rocky canyon
#

it probably calls something thats not there..

eternal needle
#

this is some mighty cursed code, and you should look at what the error says

rocky canyon
#

look inside the Logic script.. is there a GetV() function?

#

if there is.. is it Public can it be accessed outside the script its in?

oak fulcrum
#

there isnt

rocky canyon
#

well.. you can't call a function that doesn't exist.

#

hence the underlined error

oak fulcrum
#

so how can i fix it

rocky canyon
#

remove the thing that calls the thing that doesnt exist...

#

create the thing that doesnt exist

#

theres only so many options

fringe kindle
eternal needle
rocky canyon
#

why the extra funciton anyway? if its just 1 point per pipe-passed why not just pass in a 1

#

AddScore(1);

stuck palm
#

@swift crag it seems to break if it scans two walls, how do i make it so it only goes for the first?

#

like this

rocky canyon
#

and make the function just take in the int and add it to the score.. like my script does..

swift crag
rocky canyon
#

i think ur complicating things that shouldnt be as complicated

swift crag
#

Set the last point of the line renderer to wherever you hit

oak fulcrum
rocky canyon
#

probably just a missed detail..

#

when following a tutorial.. ud be suprised.. you can miss a simple step.. or even a typo.. can cause the whole system to break down..

#

and sometimes u dont even know it until u get to the end..

eternal needle
rocky canyon
#

testing periodically is the key.. every change u make save and test..

#

if it doesnt act exactly like the tutorial ur following stop.. take a breath and look around for an error

#

but yea it could be that ur just not finished

eternal needle
#

this is generally why I say people should do c# before unity, the beginner unity tutorials are "here copy paste this exactly" then you have no clue what the simplest of errors mean.

# stuck palm to i?

at the end, yeah. You could also just set the rest of the points to the same position

#

I'm not sure how costly it would be to constantly mess with positionCount at every step

#

I'm guessing that's re-allocating an array somewhere in native code land

rocky canyon
#

anyone ever play DoorKickers? any advice on how they draw out the pathing for the agents?

swift crag
#

So I would do this:

  • Set positionCount to the maximum number of points you want
  • Set some positions
  • Set positionCount to the number of positions you set
swift crag
rocky canyon

#

a LineRenderer would also probably do the trick

oh I see lol

rich adder
swift crag
#

I was reading too much into that :p

#

But yeah, those look like spliney splines to me

rocky canyon
#

ya, it like uses the navmesh pathing while u draw i think..

#

allowing u to only draw where they can move

swift crag
#

Unity's Splines package lets you create splines, then extrude meshes along them and place objects at specific points

rocky canyon
#

ohhhh really..

#

theres also a mechanic where it looks the direction that u tell it to.. so im thinking im going to need the navmesh to do one thing.. and have the aiming part disconnected completely.

#

so it gets controlled individually

assuming you've tried it without a layermask, I'm not too sure from that image otherwise

if(on left) else if(on right) else (center)

ohh u just want smoothing?

uhmm no, like i am making a endless runner game like subway surfers, it goes smoothly but it skips the lane on center (which is lane 1) and goes between lane 0 (left) and lane 2 (on right), like it acts like i didn't defined lane 1 (center lane)

#

like if i put more details, character should go between 4f, 0f, -4f in order, but it just goes from 4f to -4f, skipping 0f position completely

#

is it something to do with the unity editor?

#

same thing when u use Esc key, that has a function within the editor

#

works fine in the game.. but it will unfocus the game window inthe editor

#

f1 and f2 probably have unity functions tied to them.. wiggin something out

#

check the shortcuts and find out..

safe barn
#

there is no unity hotkeys linked to f1 and f2

rocky canyon
#

might want to use different keys while ur building and swap to the f1 and f2 keys in the build..

#

have u tested a build to see if they work in the build?

safe barn
#

i was debugging with logs, and I pressed F2 (before F1) and it logged. then I did F1 then did F2 and f2 didnt log

safe barn
#

just using the game scene

rocky canyon
#

may be a non-issue.. ```The F1 and F2 keys are commonly used by Unity for specific editor functionalities. It's generally a good practice to avoid using keys that are already reserved by Unity or other software to prevent conflicts and unexpected behavior.

In Unity, F1 is often associated with the Help menu, and F2 is commonly used for renaming selected objects. If you assign these keys to custom functionalities, you might interfere with the default behaviors of Unity's editor.```

#

F2 is Rename..

#

i know for sure i use it daily

safe barn
#

it doesnt work either way

#

any key, it wont work

Quick general question. In the download page for unity, the 2021 version seems to be the latest one. Why is that? shouldn't the latest version be 2022?

on that note, when a tutorial says that is compatibility is 2021, do I need a 2021 version (just a newest one) or will the 2022 versions also work?

image.png image.png
rocky canyon
#

well.. do u know what GetKey does?

#

every frame its held down that functions runs..

#

if u press it jsut once.. it may run 20 times

GetKeyDown would be a single keypress

i really dont know the problem, its weird

        gameObject.GetComponent<ForkliftController>().enabled = false;

    if (Input.GetKey(KeyCode.F2))

        carController.GetComponent<CarController>().enabled = true;
        gameObject.GetComponent<ForkliftController>().enabled = true;
    }
}```

use some debug's im almsot certain the input works fine.. 

ofc for it to register input correctly it would need to be run in a looop or something.. like in update
```cs
void Update()
{
    Switcher();
}```
#

u also would need to change some things around if u did that.. i wouldnt GetComponent Every frame..

#

id assign those in a start method or something.. so they're allready setup.. and then ur Update loop would keep up with the inputs

safe barn
#

hold on

Do i need these even if CarController is on a diff game object?

polar acorn
safe barn
#

Well no

#

This is just so confusing and weird. It should work

rocky canyon
#

if u go to press the first toggle button, and it can't find the component then ull get a null error.. that script will stop working and then it wont get the next input. b/c of the error.. have u checked to make sure theres no errors?

image.png
#

works fine..

#

im thinking ur gameobject that holds the forklift and car controller are disabled.. then ur script never assigns the scripts.. and then the first time u press the button it errors out.. and breaks the script

#

if this gameobject is disabled, then the GetComponents won't be able to find the scripts.. then u got errors waiting to break it

Hey spawn. Do you have 5 minutes to help me too? I got a question regarding how I could tackle a Slider for visualizing my dogs hungerBar

rocky canyon
#

you can use a slider component.. or you can use a image component with the type set to fill

worn spear
#

Yeah I have set up my sliderbar already and put it under my "Dogs" GameObject

rocky canyon
#

u can get the reference to it.. and set it manually in code with image.fillAmount;

#

i think it is

safe barn
worn spear
#

My Slider has a script called "SliderController" which should control the value

rocky canyon
#

works fine.. with the GetKeyDown.. and the .enabled =

worn spear
#

But I want to give the Health my dogs . I am just confused here

image.png
rocky canyon
#

all u need to do is assign the slider somehow..

safe barn
#

my car controller is on a completely different object, meanwhile the switcher function is inside the forklift controller on a gameobject

worn spear
#

Do i need to just get the Dog as reference in the SliderController script and then use image.fillAmount on slider? I thought I need to increaste the Slider.value ?

rocky canyon
#

once u have the reference its ez as healthBar.fillAmount = 100f;

worn spear
#

ok

rocky canyon
#

or.. yea silder uses value

worn spear
#

i see

#

Thanks mate!

rocky canyon
#

sliderReference.value = 100f;

#

or 1f;

#

i think it defaults to 0 - 1

polar acorn
rocky canyon
#

but u can change it in the inspector

#

to be 0-100

rocky canyon
worn spear
#

If i give my AnimalHunger script to my Dog it has a own value of hunger for each instance of dog and I want my collision detection in my projectile do the increasement of hunger bar

#

I did and chose only whole values instead of floats

rocky canyon
#

smart.. you can use GetComponentInChildren<> if u have access to the main object

polar acorn
rocky canyon
#

to grab teh specific slider for the specific dog

worn spear
#

I think I did understand it. Just thinking if it´s good that my detect collision script is doing the increment. I think it´s the way since I get the collision directly from the dog object so I can easily access the property of that class

safe barn
rocky canyon
worn spear
#

So basically my slidercontrol is just for showing the fill value and my collision is doing the increment part

polar acorn

#

I feel so stupid

rocky canyon
#

good catch

worn spear
#

haha

polar acorn
#

But also don't use getcomponent in update. Reference the other script directly instead of just the object, and use this for this script

worn spear
#

Is there any places where I can find other devs and share my experience and knowledge and vice versa? I feel like here there is a lot of newcomers with no coding experience. I am a Junior Developer right now so I would like to learn and share stuff with a little more advanced people then complete beginners

rocky canyon
# worn spear I just dont want to be in refactor hell 😄 I want to pass all challenges for now...

well, when ur updating UI theres a rule of thumb to do it as little as possible, for example u wouldnt want to update ur healthbar every single frame.. for no reason...

now, when it gets attacked you know the health will change.. and thats a good time to just go ahead and update its health.. so now ur updating only when the health actually changes

you can do that inside the TakeDamage() function or whatever..

#

so ur on the right track.. by thinking about incrementing it when interactions are occuring

worn spear
#

I see. Perfect yeah that was what I was thinking. For this Project it doesnt really matter but keeping it performant for scaling is always good

#

Thats why I overthink most of the stuff the beginner path is using weird ways to just implement it to not make it too complicated for beginners I guess

#

It´s basically the "fetch game" from Unity learn path

rocky canyon
#

lots of places you can share... make a project page on Itch.io

worn spear
#

Done all the challanges just kept stuck here yesterday overthinking and refactoring too many times

rocky canyon
#

and get some followers to follow ur progress 👍

worn spear
#

Thanks mate!

#

Any tips what techniques to learn next? Right now I focus on the IDE, Movement, Transform, General Script behaviour etc.

#

I think as next Topics there is important stuff like "Caching" instead of overusing the Tag feature

#

and then probably Layers and scriptable objects

rocky canyon
#

scriptable objects, might want to look into enums, and simple state machines..

#

loops, interfaces, structs, events

#

try to start using the animator and whatnot pretty soon..

#

cant think of anything specifically

worn spear
#

Ok thanks. Yeah I know loops, interfaces , structs etc. from my C# learning already so I just need to update my memory on that part since I didnt really code for months in my previous job

#

Thanks

pearl lodge
#

Every time I change something Unity says "Reloading Domain" even if its adding a blank line. How do I stop this?

Kind of annoying.

worn spear
#

Another Question I hope I am right here: I have a Projectile and that Projectile has a "DetectCollision" script. I just gave it a private property for the "damage/hunger whatever" and in the Start() -Method a Random declaration of that variable. This way every time I spawn a Projectile the Value should be random right? It always spawns a Instance of that script when the Prefab (Projectile) is being instantiated

worn spear
#

But dont get confused when you change your code and it does not change it in Unity

#

I dont recommend it. I am a Beginner though 🙂

rocky canyon
#

each time, it'll run and set a random number

worn spear
#

Thanks spawn. I think I get the understanding right now. It´s basically OOP 😄

rocky canyon
#

unless ur just that lucky/unlucky where they're all the same 😄

worn spear
#

Yeah that happens a lot to me 😄

rocky canyon
#

unity's random isn't teh greatest random..

worn spear
#

My dogs have random positions too but often they spawn near each other 😄 Didnt implement a check for Pos difference so far haha. Just want to get it done so I can move on with my life 😄

rocky canyon
#

but from what ive heard computers in general just arent good at giving a good variety of random numbers

worn spear
#

True... Computer .Random() is not rly Random I read sometimes ago

#

but better then iterating myself 😄

rocky canyon
#

ya, as u advanced ull probably end up tweaking it and making ur own RNG

worn spear
#

yp

rocky canyon
#

ohh and navigation

#

thats a big one.. NavMeshAgents / and their pathfinding

#

the better u are at that.. the more real you can get ur enemies and stuff to move about

#

at first ull just set the destination. i still do that at first.. and then as the projects progress i want them to do other things..

#

so i end up having my own implementation of pathing

worn spear
#

I see.. Yeah my Goals are simple for the moment trying to get some prototype microgames for my real business I start soon hopefully

rocky canyon
#

im currently working on this.. gotta make my own Formation type stuff

#

w/ some offsets or groupings.. idk how imma do it yet tbh

#

but this aint gonna cut it lol

worn spear
#

Looks nice hahaha!

#

I think you just need to set a offset so they dont run into eachother 😄

#

But looks cool

rocky canyon
#

thanks, i think imma do a click and drag style system.. so i can click where i want them to start forming up and release where i want them to stop

#

and then i can draw shapes like a line, or an arch, and they'll just space themselves out in that shape

worn spear
#

Sounds fun. What use case do you need this system for

rocky canyon
#

auto battler..

#

where ur units are infantry, grenadiers, or w/e

worn spear
#

I see

rocky canyon
#

and they auto shoot, but ur goal is to position them and have em facing the correct ways

#

like a puzzle / bullet hell kinda game

a Camera Rig is what u end up with.. a system of transforms and stuff that ur camera moves with and pivots around

Hi,

I'm following this tutorial:https://www.youtube.com/watch?v=LVu3_IVCzys

I began by copying everything as shown in the video but I kept receiving the below error:

"Severity Code Description Project File Line Suppression State
Error CS0246 The type or namespace name 'CustomActions' could not be found"

In the end I downloaded the project files and copy n' paste into a new script file. Still the same error message appears.

hi

how can i snap a character to ground
and stop it from walking off edges

rich adder
proud robin
# rich adder not enough info given here

so uh making a moveable character permanently snapped to the ground, like teleporting to lowest point that collides, with a threshold of how far to detect
and when moving on edge of whatever the player collides to stand on, stop player from moving so that it can't fall off the edge

rich adder
#

you could look into rayasts

teal viper
#

Sounds like you want the character to be controlled by a navmesh agent.

i wanna make Ray know Button

so how i fix this

just detect if the ray hits it

its simple

polar acorn
#

UI objects don't respond to physics raycasts

teal viper
rare urchin
teal viper
#

Check the event system info. What does it detect when you hover over the button?

rare urchin

my raycast code have nothing

#

wait

You don't need raycasts with ui.

polar acorn

No one is reading the bot

north kiln

#

what

rare urchin
teal viper
#

Same as with regular ui.

#

If your button is not reacting to hovering over it, you might want to debug with the event system.

eternal needle
# rare urchin so what i need

im not really sure what the goal is, you should just need the built in event system.
Also use google instead of chatgpt, because chatgpt just keeps going with its incorrect solutions while google will at least tell you how to detect that you're hovering over a UI object.

rare urchin
#

that all

teal viper

Chat gpt is only helpful when you know what to ask it and how to interpret/confirm the answer.

I have a Question I have a Canvas with slider + Text and a slidercontroller.cs script which controls the slider + text. My Parent Object is "FeedBar" and it´s children has the script + the Text it should change. When I save it as a Prefab and put it on a GameObject it´s fine but I loose the "FeedValue" Text association to it.

image.png image.png
rare urchin
#

@polar acornany ez way to click it

worn spear
#

So I need to manually put it back into place. Should I better keep the Controller on the Parent ? I dont know why it´s loosing it when I saved it into a Prefab and telling him he should use the TextMeshProUI element

rare urchin
#

i watch youtube and them stil told me to use raycast

polar acorn
nimble apex
#

my first question is, can you modify surface type (opaque/transparent) by code during runtime

worn spear
#

Nevermind ignore my Question pls I was just too dumb to save it in my prefab

nimble apex
#

if you can modify it, what will be the shader keyword for that

#

due to the code architecture, i must reassign a new shader and reconfigure the material of a gameobject, the code is on below

  private void AssignContentCard(GameObject parentObj, Material contentSidemat)
  {
    GameObject ContentSideCard = parentObj.transform.GetChild(0).gameObject;
    //reset shader for urp mat, it  may set in prefab when all game change to urp

    contentSidemat.SetFloat("__surface", 1.0f);
    contentSidemat.SetOverrideTag("RenderType", "Transparent");

    ContentSideCard.GetComponent<MeshRenderer>().material.shader = contentSidemat.shader;
    ContentSideCard.GetComponent<MeshRenderer>().material.mainTexture = GameManager.Instance.GetNoNumber_NumberTextureByNumberTexture(contentSidemat.mainTexture as Texture2D);//get no number card texture

    ContentSideCard.GetComponent<Renderer>().material = contentSidemat;

    Debug.Log($">>> {ContentSideCard.GetComponent<Renderer>().material.GetTag("RenderType", false)}");
    Debug.Log($">>> {ContentSideCard.GetComponent<Renderer>().material.GetTag("SurfaceType", false)}");
    Debug.Log($">>> {ContentSideCard.GetComponent<Renderer>().material.GetFloat("__surface")}");
  }

it is known that all debug log is successfully parsed , and editor can reflect the changes correctly , however , when i built it into app, the problem still there, its like the changes here didnt apply at all

rare urchin
polar acorn
rare urchin
#

i wanna do on world space

polar acorn

it work on other project but not my project

#

cuz i have rotation and zoom code in camera?

#

yea

#

Everything happen cuz my player Cam code

#

ehehehe

#

My bad

timber tide

#

if i need to describe my problem in simplest way

rare urchin
#

when i test game and click screen why i lost my cursor

polar acorn
nimble apex
#

"a specific gameobject surface render type should be transparent during runtime , it performs well and can show transparent in editor, but it showed what opaque render type will show after ran in the built app"

rare urchin
sour fulcrum
#

When you instansiate a gameobject is there a window after having the reference to the instanced object and not the asset but before the object/s trigger awake and onenable and stuff?

rare urchin
polar acorn
nimble apex
polar acorn

#

wait i think i need to explain it a bit more

sour fulcrum
#

fun

polar acorn
# sour fulcrum fun

Don't put code that depends on other code running in Awake or OnEnable. That's literally what Start is for

sour fulcrum
#

thats not what im trying to do

#

i wanted to disable certain objects inside of the instance before they could have their awake called

#

but without changing the prefab asset reference

polar acorn
sour fulcrum

has to be at runtime

Hi! I'm sort of a beginner in unity, but I'm working on a project and have some stuff that need to be delivered in a few hours, I did the hardest part already which was in the project online backend, now I just need to open that thing inside the unity project, I imported the unity-webview package but I don't really know how to make it appear inside the ui thing in the project (It's a WIP by various developers that got hired to do it)

The UI I'm targetting is in a modal and I needed to know how to put a webview inside of it where I want to, does anyone know where should I look for clues? I tried looking at a tutorial, but it didn't show, it only used the sample provided x. x

ok, i have ran the vs debug and it came up with no problems, My space bar is not working on the jump. anyone have any ideas on why i cant jump?

polar acorn

You've just got a variable

brisk escarp

#

one sec

#

my wasd keys are working

#

If you have no InputManager etc. you could also use a If statement for spacebar check

# 
{
    Vector3 projectilePosition = new Vector3(transform.position.x, _projectileHeightY, transform.position.z);
    Instantiate(projectilePrefab, projectilePosition, transform.rotation);
} ```
#

for example

#

and do Jump there

#

GetKey only checks if the key is held down

brisk escarp
#

ok, one sec

#

ok so the is grounded and the ready to jump was false i dont know what to do now, i do have gravity but im stumpted

brisk escarp
polar acorn
brisk escarp
#

Shouldn't the ready-to-jump be true? and than i should be able to jump

polar acorn
brisk escarp
#

im getting this in my console,

image.png
polar acorn
#

Okay, so then what little of the code you've shown is doing as expected. You need both of those to be true, neither of them are.

brisk escarp
#

i dont know what to do to make them true,

polar acorn
brisk escarp
#

ive done that already and i believe the problem here is that unity isnt regestring the player is on the ground so they are not working, do you think it could be a thing to do with layers?

image.png
polar acorn
#

And also I have no idea if it could do with layers because I don't know how you're setting grounded

brisk escarp
#

i call the function reset jump when the player has jumped and landed

image.png
polar acorn
#

Since it can only be called after a jump which would require it to be true

brisk escarp
#

i just tried to change it to true and still not jumping

waxen adder
#

I have my player character being instantiated after the scene loads and I want a first person camera for them. How would I achieve that simply? I'm still deeply in a prototyping stage

polar acorn

Can I use the main camera or do I add one?

#

The only difference for a main camera is the tag

Whats the difference between FindObjectByTypeand FindObjectOfType?

It is recommended to use Object.FindObjectsByType instead.```

FindObjectByType isn't a thing, do you mean FindFirstObjectByType/FindAnyObjectByType? Either way, look at the docs.

why does it even sort by ID

#

seems like such a useless operation

Because then it's consistent

But yes, they provided the overload so you can avoid that

#

Same with the difference between FindFirstObjectByType and FindAnyObjectByType

timber tide
shadow shadow
#

If I am not wrong it gets assigned the default material

timber tide
#

thought so

north kiln
#

why not just look at it

#

in the Scene view

#

and check

#

send screenshots of what it looks like, what the setup is

#

because as far as we can tell, it might not even be in the view of the camera

#

or you might be inside of it, or it might not even exist

shadow shadow
#

the position is Infront of the camera and I confirmed that by moving the camera to it.

#

and it is in the hierarchy once created

#

hella confused because it works the same if any other person does the same thing

north kiln
#

send screenshots

shadow shadow
#

of what in specific

north kiln

It selected in the scene view with the inspector and camera visible

Hi, its my first time using Unity and I'm trying to make a simple 2D game. I have this movement for my player, and it worked fine for awhile.

if (Input.GetKey(KeyCode.W) && Input.GetKey(KeyCode.D))
{
    myRigidBody.velocity = (Vector2.up + Vector2.right).normalized;
}
else if (Input.GetKey(KeyCode.W) && Input.GetKey(KeyCode.A))
{
    myRigidBody.velocity = (Vector2.up + Vector2.left).normalized;
}
else if (Input.GetKey(KeyCode.S) && Input.GetKey(KeyCode.D))
{
    myRigidBody.velocity = (Vector2.down + Vector2.right).normalized;
}
else if (Input.GetKey(KeyCode.S) && Input.GetKey(KeyCode.A))
{
    myRigidBody.velocity = (Vector2.down + Vector2.left).normalized;
}
else if (Input.GetKey(KeyCode.W))
{
    myRigidBody.velocity = Vector2.up;
}
else if (Input.GetKey(KeyCode.S))
{
    myRigidBody.velocity = Vector2.down;
}
else if (Input.GetKey(KeyCode.A))
{
    myRigidBody.velocity = Vector2.left;
}
else if (Input.GetKey(KeyCode.D))
{
    myRigidBody.velocity = Vector2.right;
}
else
{
    myRigidBody.velocity = Vector2.zero;
}

However, I'm now adding knockback for when you get hit by enemies.

if (collision.gameObject == player)
{
    playerRigidbody.AddForce(direction * -knockback, ForceMode2D.Impulse);
}

I'm using the AddForce() method for this, but since myRigidBody.velocity is set to zero at every frame, the two counteract each other. Is there any way for me to do knockback without velocity? Or should I rework my movement code?

I just joined this server, if this is in the wrong channel lmk.

How do I restrict a camera following the player to only moving along the Y axis? I tried adding a rigidbody with constraints to it but it didn't work. Is there a better way?

#

Your current code confuses me though, so maybe you are looking for something else?

fringe kindle
modest dust
# fringe kindle Here's the script, for context

Playing around with rigidbody constraints won't help in any way if you set the transform position directly and not via the rigidbody. In your case, just initialize your camera with a default position and then simply update only the Y position

private Vector3 m_position;

public void Awake() // Or Initialize() called manually if you have to move the player somewhere first or reset the position a few times ig
{
  m_position = player.transform.position;
  m_position.y += 1.9f;
  // And some other modifications if you want, since I see that the z position is also different in your code
  cam.transform.position = m_position;
}

public void Update()
{
  m_position.y = player.transform.position.y + 1.9f;
  cam.transform.position = m_position;
}
