[short hazel]

And for the error, just expose a getter for the property. Do not declare the field

[tender stag]

oh alright

yeah works

thanks you

[short hazel]

I'd rename SetDurability to something else, since it does way more than just setting the durability

Something like UpdateDurability

[tender stag]

whats wrong?

[short hazel]

Properties must be in PascalCase

Won't fix the error, but at least the naming conventions are applied

[polar acorn]

Those aren't properties, those are variables.

[short hazel]

Errors, these are fields in your class, not properties

[tender stag]

so like this?

[short hazel]

[field: SerializeField] public float Durability { get; set; } -- pretty much the same as in the interface decl

[rich adder]

so how do i know how you sset this up ?

provides no context then asks for help . A+ kid

then insult help

smart

w/e fuck this..

[tender stag]

one last thing

i cant have a header

[short hazel]

Target the field too :)

[tender stag]

oh yup works

thanks so much

much cleaner now

[rich adder]

go drink a glass of milk kiddo

[queen adder]

can anyone dm i need help with starting to code simple player movement

[broken hazel]

I, uh, need a little help with - same

[tender stag]

what is bro yapping about

[tender stag]

is there any way to default it to 100?

like durability and max durability

on default

[rich adder]

= 100

[short hazel]

Sure, after the accessors declaration

... { get; set; } = 100;

[tender stag]

yup works

properties are so cool

[broken hazel]

Sry

[tender stag]

i didnt know they were so useful

[short hazel]

That's also compiler trickery, the value gets put on the backing field like the attributes. Most of modern C# is compiler trickery and syntax sugar nowadays

Switch expressions? Compiles to a bunch of if statements

etc.

[broken hazel]

Can some help me with character controls? I've look some up before but they were only allowing me to look in one direction. I believe this is how I ask

[tender stag]

rigidbody or character controller

[broken hazel]

Um just to get a capsule to move in all directions

Idk how to put it

[tender stag]

dm me

[swift crag]

you're going to need to provide a lot more information.

[broken hazel]

It won't let me DM you

[tender stag]

accept friend request

[wintry quarry]

Camera Rotation isnt clamped to Time.deltaTime
What on earth does this mean?

YOu have to show code

but yeah that was a really weird way of saying "my code is framerate dependent, help"

this is good and fine

there is no need for deltaTime here

mouse input is already framerate independent

adding deltaTime in this calculation would be erroneous

[tender stag]

how do i make a formula to calculate the amount i need to add to the break percentage?
durableItem.BreakPercentage += Random.Range(12.5f, 25f);

like for example my ak has 100 MaxDurability and the Durability can go between max and 0

like i want it to add more to the break percentage the more then item is broken

so the lower Durability the more to add to BreakPercentage

did this
durableItem.BreakPercentage += (durableItem.MaxDurability - durableItem.Durability) / durableItem.MaxDurability * 35;

[eternal needle]

this is python..

[crisp token]

whoops wrong discord lol sorry

[cobalt granite]

If I want to make a sphere grow over 2 seconds smoothly how do I go about that within a coroutine?

[rich adder]

just add the amount while timer seconds is less than 2

[modest dust]

for (float t = 0; t < 2; t += Time.deltaTime)
{
   // Size Lerp here with progress being t / 2
   yield return null;
}```

[rich adder]

timer = 2f;
currentTime= 0;
while( currentTIme < timer){
//scale sphere
currentTime+= Time.deltaTime
yield return null;}

[cobalt granite]

Okay thank you, these helped a lot

[rich adder]

interesting, i forget for loops are like similiar to while loop but with iterator xD

[modest dust]

I rarely ever use while loops

unless it's a boolean or something more complex

[rich adder]

they used to frighten me lol but they're quite powerful to do retries and stuff

[modest dust]

scary while loops 👻

basically a for loop, but you declare and update everything out of the () scope

well, you could update within () but that's just weird

Anyways, caesar out, time for some programming dreams

[amber spruce]

so i have it to my player can eat objects to get bigger but the camera doesnt get further away or anything so the player fills up the whole screen how do i fix this

[rich adder]

make it move on Z a bit

add offset if you use cinemachine

[amber spruce]

so im using cinemachine

how do i offset it

[rich adder]

there should be an offset component

[amber spruce]

i cant find one

[static cedar]

Double for each is a good use case.
But use for loops instead for that.

for ((IEnumerator a, IEnumerator b) = (_a.GetEnumerator, _b.GetEnumerator); a.MoveNext() && b.MoveNext; )

I use tupples to declare multiple stuff in a for loop too often.

[amber spruce]

im using the cinemachine freelock

[amber spruce]

how do i change that via a script

[swift crag]

store a reference to the CinemachineCameraOffset and modify it

[rich adder]

void ChangeOffset(float sumValue)
{
var offsetComponent = cmvirtualcamera.GetComponent<CinemachineCameraOffset>();
offsetComponent.m_Offset = new Vector3(0, 0, sumValue);
}

yeah just store it

since ull change it often

[amber spruce]

what do i put for sumValue

do i change that at all

[rich adder]

its an example.. the parameter is in the method, wouldn't hurt if you did some refresh on c#

[amber spruce]

yeah i gotta do a refresh tutorial lol

[amber spruce]

so what do i set it to

[rich adder]

have you tried actually testing values on the offset component at runtime to know which values u need?

[amber spruce]

no lol

not sure how to

also the var i assume thats my variable right

[rich adder]

forget the code right now

in playmode, change the offset in the inspector

on the component

[amber spruce]

yeah i did that

[rich adder]

ok so which Z value looks fine when you have big sphere?

[amber spruce]

well it will always get bigger

so it should just increase by a certain amount

[rich adder]

thats why its a variable

so you can change it every time you change size

[old lance]

hi so i recentley created an organization with my friend and i made a project how do i get him on it

[rich adder]

just make sure u store the reference so you don't get it everytime u change value

[rich adder]

this is not a code question

[amber spruce]

would this not work. just changing the offset plus the variable

[rich adder]

wdym plus the variable

[amber spruce]

so like offset += var

i think thats the right syntax

[rich adder]

you can just add an offset + size of sphere

so you have a consistent value

[amber spruce]

oh ok that sounds way better

how would i do that though

[amber spruce]

sorry to bother you but i only got like 20 minutes so how would i do this?

[unreal imp]

How do I ensure that the script for my object does not affect his childrens except for one specific?

[rich adder]

        cinemachineOffset.m_Offset = new Vector3(0, 0, -sphere.transform.localScale.magnitude) ;

[amber spruce]

where do i put that

[rich adder]

wherever you change your sphere size?

how does sphere grow?

[teal viper]

Just don't touch any objects aside from the one you do want to affect.

[amber spruce]

ok so there are 2 errors

[rich adder]

um

you copied variables that u prob dont have

don't just blindly copy

[amber spruce]

which are variables?

[rich adder]

the ones that error says don't exist..

[amber spruce]

so for the first one should this be the variable

    public CinemachineVirtualCamera cinemachineOffset;

[rich adder]

no CinemachineVirtualCamera is not the right component

think back to which one you're trying to change..

[amber spruce]

oh

    public CinemachineCameraOffset cinemachineOffset;

that

[rich adder]

you probably want an additional parameter to adjust the offset

incase magnitude alone will create too much of prefix distance

[SerializeField] private float offset = 0.2f; // try different values, positive value = closer to sphere

cinemachineOffset.m_Offset = new Vector3(0, 0, -sphere.transform.localScale.magnitude + offset) ;

@amber spruce

[amber spruce]

so for some reason the more it gets bigger it makes it so you cant move the angle your looking at higher so you end up looking threough the ground

[rich adder]

you'd need to add a Cinemachine collider

mind you this isn't the way to do, just a way to do it. for Free Look it gets more tricky too

[amber spruce]

i cant find a camera collider is there one or do i make my own

[rich adder]

its a cinemachine component

*Extension

[amber spruce]

still ends up being like this

[rich adder]

what am i looking at

[amber spruce]

my camera cant go further from that so i cant look straight

[rich adder]

play around with all 3 rigs

i just tested it on the default cam and it worked for m

[amber spruce]

weird

thats my collider

[rich adder]

i was talking about the rig

[amber spruce]

this??

[rich adder]

these

they determine your look angles per rig

[amber spruce]

should i change that

[rich adder]

you have to play around in playmode with settings that make most sense while the ball is big

[amber spruce]

aight

[amber spruce]

what would be stopping me from looking up is there something stopping the y rotations

[rich adder]

you can change the rotation here

as you change that you have to change the height/radius on rig

play with the values until its correct

[amber spruce]

so like i cant just keep looking up thats my problem

that changes the rotation doesnt stop me from going to high

[rich adder]

can u record vid how it looks like

[nova vortex]

im tryig to build the facepunch.steamworks

and it just :(

anyone know how I fix this

[amber spruce]

https://jmp.sh/EqoypInl

i cant look any further up

normally its fine

but when i get big it aint

[rich adder]

maybe instead of offset change size of rig with the same value

yeah I think that will work better..

remove the FollowOffset

try this instead

        freelook.m_Orbits[0].m_Radius = sphere.transform.localScale.magnitude + offsetTop;
        freelook.m_Orbits[1].m_Radius = sphere.transform.localScale.magnitude + offsetMid;
        freelook.m_Orbits[2].m_Radius = sphere.transform.localScale.magnitude + offsetBottom;```

[sour fulcrum]

Dipping my toes into how Matrices work and stuff and think just some names are throwing me off

If I set an objects Gizmos.matrix to transform.localToWorldMatrix or transform.worldToLocalMatrix. Is that literally just the same of having it's origin be based on the objects local and world values straight up? the names of the properties had me wondering if theres anything else being added but I just need someone smarter than me to clarify ❤️

[amber spruce]

that?

[rich adder]

no the component you added..

CinemachineCameraOffset

this clips you through the floor

[amber spruce]

so that

[rich adder]

ye

[amber spruce]

what do i put for freelook and offsetbottom, mid, and top

[azure zenith]

Is it okay to use Destroy.() for collecting ammunition?

[amber spruce]

smth like this for the variables im missing

 public CinemachineFreeLook freelook;
 public float offsetBottom = 0.2f;
 public float offsetMid = 0.2f;
 public float offsetTop = 0.2f;

[rich adder]

yes

        freelook.m_Orbits[0].m_Radius = sphere.transform.localScale.magnitude + offsetTop;
        freelook.m_Orbits[1].m_Radius = sphere.transform.localScale.magnitude + offsetMid;
        freelook.m_Orbits[2].m_Radius = sphere.transform.localScale.magnitude + offsetBottom;```
the order is reversed tho, i edited old msg

[rich adder]

wdym by collecting ?

[azure zenith]

Collecting any gameobjects

[rich adder]

as long as they're not stored in a list sure

destroying and instantiating comes at a cost, ideally you want to re-use the same objects with pooling

[azure zenith]

Interesting

Why would you want to use a list?

Is that when all the items are the same?

[rich adder]

idk if you collect something and it stores in a list, if you destroy it just becomes "Missing" in the list

like if you have collectables or something

[azure zenith]

Oh, okay

[amber spruce]

so now its same problem as before it still is way to close

[rich adder]

so increase offset

[amber spruce]

you had me get rid of offset though

[rich adder]

the variables you just made dude

#💻┃code-beginner message

[ashen ferry]

is putting all events from all scripts in one dedicated mega events script anyone can run/subscribe a thing cause im boutta do it to eradicate some macaroni

[amber spruce]

changing them doesnt do anything'

[rich adder]

are you changing it in the code or inspector ?

[amber spruce]

inspector

[rich adder]

select the camera and screenshot the gizmos in playmode

[amber spruce]

gizmos??

i gotta go for tonight i will continue this in the morning

[livid jacinth]

I'm getting an error and I'm not entirely sure why, maybe someone can point me into the right direction? I have a script added to a game object as a component, that script has an empty array in it. When I try to change the size of the array in the inspector, it completely removes the array and the ability to change the size of it and a wall of text comes up in the console starting with "NullReferenceException: SerializedObject of SerializedProperty has been Disposed."

I can put the rest of it in a pastebin if more is needed

[rich adder]

are you in 2022

[livid jacinth]

yes i am

Also, it may make a difference, I'm trying to edit it on a prefab, not in any scene

Hm, it seems to work if I open the prefab and not just click on it once in the project folder

[rich adder]

2022 is buggy af

i get spammed with those on 2022.3.3

try to update to latest patch if you're not on it

[livid jacinth]

I'm on 2022.3.10f.1

I'll have to double check but I think that's the latest one

[rich adder]

I think its 11 but for me it fixed those errors at least, hmm not sure maybe its a script?

[livid jacinth]

It's giving me references to other scripts like "UnityEditor.SerializedProperty.get_intValue () (at /Users/bokken/build/output/unity/unity/Editor/Mono/SerializedProperty.bindings.cs:996)"

and when I click on it to inspect it, it opens up and there's nothing in there

It was working fine until like 10 minutes ago

[rich adder]

do you have version control installed?

try removing it

or restat unity / default layout

[livid jacinth]

I tried to change an array to be able to use nested arrays, when I declared the variable I used [][] instead of just [] and it went up in flames

[rich adder]

ohhh

[livid jacinth]

Then when I changed it back to just [], it's still giving me issues

I installed version control but I haven't done anything with it yet unfortunately

[rich adder]

the only strange thing about this is unity doesn't serialize [][]

but I don't know if it would blow up like that just changing it once array was serialized

[livid jacinth]

It removed the elements entirely and I figured "ok i guess it doesn't work like that", changed the script back and now it's doing this lmao

[rich adder]

just tried it and it doesn't blow up for me

[livid jacinth]

I may have to try changing the editor version then

[hybrid karma]

why when i set a float to "0.8f" it becomes "0.800000011920929"

[livid jacinth]

oh i forgot I also tried to do [ , ] as well thinking it would do the same thing

[livid jacinth]

this is normal for floating point numbers to do

https://learn.microsoft.com/en-us/cpp/build/why-floating-point-numbers-may-lose-precision?view=msvc-170

[hybrid karma]

right but how do i make it actually 0.8

[sour fulcrum]

you dont

[livid jacinth]

you could try using double instead of float

[slender nymph]

why

[hybrid karma]

0.800000011920929 is greater than 0.8

[slender nymph]

what are you actually trying to achieve

[hybrid karma]

when i compare the variable to 0.8f it says the variable is greater, i need it to not do that

[slender nymph]

let me guess, you're trying to use == with floats?

[hybrid karma]

yeah

[livid jacinth]

Math.Round(yourNumber, 1) will round it to the nearest tenth

[slender nymph]

yeah that's your problem. use Mathf.Approximately when comparing floats

[livid jacinth]

Also that

[rich adder]

floats can almost never be exact so == bad

[hybrid karma]

but why is a variable i set to 0.8f different to 0.8f

[rich adder]

because float point imprecision

you should look that up

[rich adder]

https://timothybramlett.com/floating-point-imprecision.html

[sour fulcrum]

weird comparison but imagine if you bought a box of cereal that said it had 8000 pieces in it and you counted them all. it's probably around the 8000 mark but it's more than likely higher or lower just because of how the cereal machine fills the box

[slender nymph]

and the crumbs. those are parts of pieces
and the inaccuracies in floats are like the crumbs

[polar acorn]

Imagine you had 100 index cards to write every number between 1 and 1000. You can't give each card its own number, so you put some of the commonly used numbers on the cards and accept that if someone picks something else, they're gonna get "close enough"

[hybrid karma]

i have to rewrite my scripts because 0.8 =/= 0.8

[polar acorn]

If someone asks for 84 and your closest card is 85, if they handed someone their 85 and said "hey is this equal to 84?" the answer would be "no"

[summer stump]

Note that this is not about c# or unity or anything. It is inherent in computers

[polar acorn]

0.8 equals 0.8, but 0.8f does not necessarily equal 0.8f

[summer stump]

Yep. Never do == with floats/doubles/etc

[polar acorn]

just use Mathf.Approximately

[rich adder]

   public static bool Approximately(float a, float b)
        {
            return Abs(b - a) < Max(1E-06f * Max(Abs(a), Abs(b)), Epsilon * 8f);
        }```
🙂 behind the scenes the magic

[hybrid karma]

whats the thing for <= and >=

[polar acorn]

<= and >=

[sour fulcrum]

if firstValue is greater than secondValue or firstValue is equal to secondValue

it's two checks built into one for convenience 😄

[hybrid karma]

no for floats

[summer stump]

Those are fine to do with floats as is. There is no other thing

[slender nymph]

<= and >=

[hybrid karma]

what

[rich adder]

thats what you would use when you dont use Math.Approx

> < <= >=

[summer stump]

Floating point imprecisions means they won't be exactly equal 🤷‍♂️

But less than and greater than can be easily checked. Why would there be anything else?

[hybrid karma]

but if i do var <= 0.8 and var is 0.800000011920929 it will say its greater instead of equal

[summer stump]

Yep.

[hybrid karma]

so what is the <= version of approximately

[summer stump]

There is none

[polar acorn]

<=

[slender nymph]

why don't you show your actual code if you are having a problem with your code

[polar acorn]

Don't expect equals to be equals

But less than works fine

[north kiln]

Perhaps start a thread too

[sour fulcrum]

theres no easy way to use Gizmos.DrawCube in a function outside of OnDrawGizmos or OnDrawGizmosSelected right

[north kiln]

Nope

[sour fulcrum]

pain

[north kiln]

I have a package that practically functions an expanded Debug.Draw, all wireframe though https://github.com/vertxxyz/Vertx.Debugging

[sour fulcrum]

Ooo I might peep this then

Actually if you have a sec, I don't really know how to articulate my issue without a massive text dump but tl;dr I'm trying to rotate a gizmos to reflect my transforms rotation but when I set the gizmos matrix to my transforms localmatrix the drawing im trying to do is wrong because my positions im using already have the transform.localPosition baked in so its getting added twice.

currently i wanted to try and make a custom DrawCube function that basicially -='s my position so it like offsets it correctly but on the drawcube function side so i dont have to change my position directly

if that makes any lick of sense

[north kiln]

You should set it to the transform's matrix and then work locally, so the position of the object is at Vector3.zero

[sour fulcrum]

I'm trying to do most stuff locally but I do need to consider world stuff for the game mechanic i'm trying to pull off aswell

I have a 3d tile matrix that I have "synced" to it's transform position but I want the parent of that object to be able to move and rotate aswell

[livid jacinth]

lmao I tried changing it to the new version of the editor and it's still happening

[ashen ferry]

is class holding all the events anyone can run and subscribe to a thing lol

[sour fulcrum]

I have this cute little 3d matrix here that stores all my tiles but this is going to end up being a cube like this so I can rotate and move the Planet's object that's in the center and have each face-child and their respective 3d matrix adjust correctly

forgive my terrible perspective drawing skills

[queen adder]

how to unselect object in eventsystem?

nvm it have its method

[topaz mortar]

next time show the error message

[dim wharf]

Is there any way for the Execute() to know who did the method call without putting my object as a parameter? Want to make things look generic

[dim wharf]

this is in my player class

considering the observer pattern

[wheat hull]

do you have the action in a different class from the one that is calling it ?

[dim wharf]

yes

[wheat hull]

and you want the action to have the information of which object did the call

[dim wharf]

yes

[wheat hull]

yeah im pretty sure the only way to do that is by passing the object as a parameter, but I dont see that being a problem in any way.

[dim wharf]

Maybe you're right. I was simply obssessing on trying to make it look clean

[wheat hull]

yeah i get what you mean, although what exactly are you trying to do ?

why do you need the action to know which class called it

[dim wharf]

the playerClass has an int damage and the UnitAction im currently executing is a Strike(target)

I just want it to look like player.doAction(new Strike(target))

simply adding the player to the parameter makes things much simpler tho lol

[wheat hull]

but where is the action ?

[eternal needle]

you could use the stacktrace from System.Diagnostics, although idk the purpose of this really

[wheat hull]

is that in a separate class ?

[dim wharf]

it looks something like this

[wheat hull]

Im trying to understand why you need to know which class called the action

[dim wharf]

yes it is in a separete class

and tested it like this

the book I'm following (that teaches about the command pattern) passes the doer of the action as well. I guess I'll just surrender and do that as well

[wheat hull]

if you really need to know where the action is being called then sure, but I dont know if this is the best way in general to approach what you are doing.

[light moss]

I want to make the Enemy Jump every 2 seconds however the enemy GameObject isn't doing that. What is wrong with my code?

[teal viper]

Can't see any issue with the code.
Are there any errors?
Debug your code with logs or breakpoints.

[summer stump]

A lot of the code has a yellow bar on the left (meaning unsaved). Have you saved it since adding the jump?

[light moss]

Yeah I have. I think an issue might be with my Waypoint Follower script. I think that may interfere with this script

[summer stump]

If you are setting velocity in it, it will override the jump

[light moss]

This is my Waypoint Follower script I have for my Enemy. I do not see how this can interfere with the Enemy Jump Script

Even when I disable the Waypoint Follower, the Jump script still does not work

[summer stump]

You are directly setting the transform in this script. Which is kinda like teleporting

which would probably interfere. But it doesn't affect velocity (teleporting doesn't impart velocity), so I dunno

Generally you don't wanna mix rigidbody and transform based movement.

It can work, but you gotta be careful.

[topaz mortar]

Why does my healthbar prefab disappear when I zoom in too much?

[young warren]

Because it went behind the camera I assume

[topaz mortar]

oh, didn't know that could happen

[light moss]

I'm an idiot. I forgot to add the Rigidbody2d Component

[summer stump]

Ha, I was just about to say, "Wait, do you have a Rigidbod- wait where'd the video go?"

Good job getting it on your own though

[teal viper]

It must've been throwing errors then.

[eternal needle]

i was gonna ask where it was as well before the vid was gone, you should also have your console open when going through issues. I suspect your console was throwing errors like crazy since the rb2d reference was gonna be null

[light moss]

This is my first Unity game so I have a lot to learn. I will check console more often thank you

[distant mesa]

is there a way to put Pose variables together? like Pose + Pose to merge the values?

[sour fulcrum]

your example is just how it works yeah

myValue = myValue + myOtherValue

adds your othervalue to your value, a shorter way of doing it is

myValue += myOtherValue

or if you want a new combination value

myCombinedValue = myValue + myOtherValue

[teal viper]

What's a "Pose" variable?

[distant mesa]

i keep getting this error tho

[teal viper]

What type is it?

[distant mesa]

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

im new to this so i dont fully understand it

[teal viper]

As you can see in the operators section, there's no addition operator:

[distant mesa]

hmm okay

[sour fulcrum]

When a parent transform has rotation and a child transform changes its world rotation and world position to reflect that change, what is it actually doing calculation wise?

[gaunt ice]

apply the same transformation matrix to all children

[sour fulcrum]

I don't understand what you mean by this

[teal viper]

Position+rotation+scale are represented as a matrix internally. You can do some matrix math to rotate/move/scale objects. When a parent transform is changed, it's transformation matrix is recalculated and applied to all the children.
Or something like that.

[sour fulcrum]

Do you know what i'd want to look into if I want to do that myself?

I have a 3d array of positions and I want to apply my transforms values to them like each of them were children

[gaunt ice]

you can learn the math but strongly suggest you dont recode the math yourself, you can learn how to use matrix4x4 etc

[sour fulcrum]

Oh yeah I have no desire to be like a super wizard nerd in this regard, my goal is just to re-create the end result

advice on utilising whats already there via matrix functions would be more than ideal

[gaunt ice]

https://docs.unity3d.com/ScriptReference/Matrix4x4.html

I've looked at this a few times over the last day or so and while I understand there are things I would want to use there. I don't have the math comprehension to put it together

[gaunt ice]

you may get started with 2d and 3d vector and transformation math first

[hollow orbit]

hey, followed a tutorial for a basic enemy ai, but it gets stuck on the edges of platforms. is there a simple fix for this?

maybe not edges of platforms specifically, but the edges of the mesh

[teal viper]

Hard to say anything without more context.

[hollow orbit]

what do you need

[gaunt ice]

tutorial, script, what part the script fails

[light moss]

For some reason my Enemy Way Pointer Destroyer Script does not have a Checkboxto disable it. How can I fix that?

[slender nymph]

that means it has no unity messages that only run when it is enabled

in other words, disabling it will do literally nothing

[light moss]

But it would in my case

[gaunt ice]

maybe it is requried by other component

[light moss]

It will prevent the enemy from freezing

[slender nymph]

how

are you checking that the component is enabled anywhere?

[light moss]

This is the script

[slender nymph]

okay so disabling that will do literally nothing at all

[light moss]

When I remove the component the enemy does not die which is what I want. However I would prefer that to be in a enable/disable checkbox in case I want to add it back

[slender nymph]

nothing in this component is affected by whether it is enabled or not

[hollow orbit]

https://www.youtube.com/watch?v=UjkSFoLxesw&ab_channel=Dave%2FGameDevelopment
everything set up like in the video except i have a lot of elevation changes. could i be that the enemy gets stuck when it tries to go somewhere that's a different elevation but cant figure out how to get there?

Hi all,

Sooooo, I'm trying to build a pretty simple vehicle controller and at the moment I'm a little stuck on suspension stuff. I have an Empty which is the suspension 'target' that I'm trying to raycast to the ground and then move the target to the hit.point, problem I'm facing is that the target object needs to be a child of the main vehicle body, but when it is, the raycast doesn't move the object. (if I unparent it, it works fine), I'm a little confused as to why the script isn't 'overriding' the position.

Can anyone see where I'm going wrong please?

public class SuspensionTargetVPosition : MonoBehaviour
{

    [SerializeField] Transform targetWheel;
    [SerializeField] float targetHeight;


    // Update is called once per frame
    void Update()
    {
        RaycastHit hit;

        if (Physics.Raycast(transform.position, transform.TransformDirection(-Vector3.up), out hit))
        {
            Debug.Log("I hit Something");
            Vector3 groundIntersectPosition = hit.point;
            transform.position = groundIntersectPosition;
        }
    }
}

[sour fulcrum]

Is there a suggested way to stop jitter in a character controller when it get's moved by other code and/or parent transform changes?

[royal ledge]

I have encountered a bit of a structuring problem, let's see if i can explain it so it makes sense. My player has a script called "PlayerGun". If the player runs into a gun he picks it up and the guns data get copied into that script and then that script handles shooting/rotation etc. Pretty simple. Now i have encountered a problem where my guns has been getting more complicated and i feel like my script holds unecessary methods for things they don't use. For example i now have guns that create bullets that check for collision and guns that create raycasts that check for collision. So I could split up the logic into abstract classes (PlayerGun -- PlayerGun_Bullets -- PlayerGun_Raycast). But then i would have to hot-swap between components on the player, depending on what type of gun they pick up. Probably need a script on the player that handles that hot swapping too. Is this a feasible thing to do?

[spare umbra]

I have a dashing code and it workes fine

However when I put the player at origin and dash it sometimes goes 3.2 units and sometimes 4.8

[teal viper]

It's a fine solution. Another way to do it is to delegate the shooting logic to the specific item object instead.

[spare umbra]

How can I fix it?

Ignore the debug log

[teal viper]

To fix it, first identify the source of the issue. Is your velocity always of the same magnitude?

[spare umbra]

Yeah

it's same

[spare umbra]

I can share my screen if you want

[teal viper]

If it's the same, then the problem might be with you relying on time instead of fixed updates count within that time period. Might want to yield yield the next fixed update(or a few in a loop).

[spare umbra]

Might want to yield yield the next fixed update(or a few in a loop).

What do you mean by that? Can you explain it a bit?

[spare umbra]

It's likely what you're saying is right

[royal ledge]

Alright, awesome, thanks

[azure zenith]

I am unable to drag and drop an AudioSource clip into another gameobject, any idea as to why?

[teal viper]

Check the API docs page for YieldInstruction.
That or avoid using a coroutine at all.

[spare umbra]

Hmm that didn't work too

[teal viper]

Well, you still have the waitforseconds 😅

[azure zenith]

.

[spare umbra]

Yeah but if I remove it I can't control the dash duration

[teal viper]

With time, no. But you can control it with fixed update frames count.

The issue is because you're trying to control the duration with time.

[chrome scarab]

[SerializeField] what does this mean?

[teal viper]

Maybe if you wait for the fixed update at the very beginning of the coroutine it might work, but if you ask me, that's still unreliable.@spare umbra

[teal viper]

It means that the field should be serialized.

[chrome scarab]

Just writing it won't serialize it, right? xd

[teal viper]

It will. Just adding the attribute would serialize it. Just like a public field.

Assuming the object that the field belongs to is serialized as well.

[chrome scarab]

So is it enough for me to just write it for the save system? an extra method or xml serialization etc. Don't I need to do it?

[teal viper]

Depends on what you're using in your save system.

[winter shore]

Hello, can someone tell me what is wrong on the underlined code and how to fix it ?

[chrome scarab]

I don't use. That's what I'm trying to say. Do I need to write another save system or is it enough to write it at the beginning of the variable I want to save?

[chrome scarab]

u cant use SetActive

[winter shore]

Oh, what is the replacement of it then ?

[chrome scarab]

use IsActive or Active

[teal viper]

Of course. Save system is a whole separate system that you need to implement. The attribute just makes unity serialize the field.

[chrome scarab]

!this.Flashlight.IsActive
or
!this.Flashlight.Active

[chrome scarab]

okay thx

[teal viper]

SetActive does not return anything, so you can't use it as a condition.

[chrome scarab]

setactive is a void method. You cannot use void methods as condition xd

[chrome scarab]

use this.

[winter shore]

It says it's an obsolete way of saying it. But works nevermind.

[chrome scarab]

https://docs.unity3d.com/ScriptReference/GameObject-activeSelf.html

!this.Flashlight.activeSelf

or

!this.Flashlight.activeInHierarchy

[chrome scarab]

Yes, because that method was replaced with a new method. It is in the old method, but it is trying to say that you can also use the new method.

[winter shore]

And what is the code to state if that a gameobject is unactive ?

[chrome scarab]

false?

[winter shore]

Alr

[chrome scarab]

But I advise you to put a light on your flashlight object and make that light active. not the object itself.

Because if you close the object itself, you cannot use the object itself to open it back.

[winter shore]

So I could just deactivate the light itself ?

From its component ?

[chrome scarab]

yep exactly.

If you disable the gemobject, you cannot use the scripts inside the gameobject to reactivate it. If you try to use it you will get an error.

[winter shore]

And how come you could still reactive the game object with everything with it too, right ?

That's an option, I tried for other gameobjects and it worked.

[chrome scarab]

You will get the error "Object reference not set to an instance of an object". or "null reference exception".

[sour fulcrum]

its like turning your bedroom ceiling light off vs turning the whole house power off

[chrome scarab]

hmm I don't know. I got object reference when I tried it.

[teal viper]

Disabled objects still exist. They're not destroyed. So you shouldn't get a null reference on an existing reference.

If you try to find it with one of the find functions, you might not be able to, this getting null. But that's a different case.

[chrome scarab]

Shouldn't you not use that object and its content when you disable it? Do I remember wrong?

[chrome scarab]

It may not be null reference, but I remember getting an object reference error when I tried to use disabled object.

Maybe my engine version is outdated, I'm not sure.

[winter shore]

Basically, what I want is to toggle a gameobject, which is a flashlight. I would like to be able to toggle it on and off with the same key button.

[teal viper]

No, it doesn't matter. You can use it. Although it makes little sense to disable it if you're using it.

[teal viper]

Yes, that's what I mentioned with the find functions.

[gaunt ice]

call method on script on a disable object is completely fine

[chrome scarab]

The problem I had was something similar to this. I was using something in the trail compoment to delete the trail, and it was disabling the human gameobject, so I kept getting errors, I solved it later.

[modest dust]

Just keep the script enabling/disabling the gameobject off the gameobject you're enabling disabling

Once a gameobject is disabled all it's components are also disabled

so no Update, LateUpdate, Awake, etc

but calling manually from other active scripts still works just fine

[chrome scarab]

Yes, that's what I'm talking about.

If you connect this script to flashlight and disable flashlight, shouldn't that script not work?

[modest dust]

Unity just won't call the methods that it normally would

But you can still call them externally from other scripts

[chrome scarab]

But the friend wants to activate it again from the same script file.

[chrome scarab]

That's why I told him to disable the light component instead of disabling flashlight.

[candid oyster]

Hey guys I wrote this very bad code thats very long. I think that I can make this shorter just by using a 2 dimensional list. Is that correct? If so, how would I go about making a 2d list. If someone could send a link to a guide or a good doc page, I would by thankful. Thanks!

[chrome scarab]

yandere coding

[candid oyster]

yeah, thats why im trying to fix it

[gaunt ice]

do you know A+1=B?

[chrome scarab]

I'm not very good at coding but I think you could use a foreach or switch case to fix this.

[gaunt ice]

so given an coordinate [A-Z][0-9], you can get wasd direction by adding vector2.up, right etc

[languid spire]

Dictionary<string,string[]> myDict

add using

myDict.Add("A1", new string[] { "B1,"C1","D1" });

access using

string[] myCoords = myDict["A1"];

[candid oyster]

Thanks

Ill look into these options

[gaunt ice]

btw i will not represent coordinate in forms of string

string is inmutable and create lots of garbage, instead try

struct{
  char row;
  char column;
}
```total 4 bytes

[candid oyster]

what does struct{} do?

[burnt vapor]

Same thing as a class but as a value type instead of a reference type. If you don't know what it is big chance you don't need it since this mostly falls under improving performance. I don't understand why it's being posted in a beginner channel to begin with.

[chrome scarab]

public static bool IsCoordinatesTrue(string a, coordinate b)
{
    return (b == a) ? true : false;
}

I've never used coordinates in unity, but you can use a function like this to check condition. Then write a function in the same way to change the coordinates. It has 4 parameters and changes down up left and right.

[candid oyster]

this got overwhelming

[burnt vapor]

It seems like you could just use a 2d array here. I assume the coordinates represent a spot in a 2d grid?

[candid oyster]

is a 2d array like a 2d list?

[burnt vapor]

So it's a matter of determing the x and y position

[candid oyster]

when i searched up 2d list I saw a lot of "arrays"

[candid oyster]

yes, spot in 2d grid

[burnt vapor]

They are practically the same thing. I would advice you use an array unless your grid can grow bigger or smaller

[candid oyster]

yes

alr, Ill just look into arrays then

I think that it will be the easiest for me

[burnt vapor]

I'd say see what an array is first

Then perhaps look up c# Lists, and then the difference between the two (spoiler: a List is a "resizeable" array)

[candid oyster]

yes, Ill look into it

ty

[chrome scarab]

If he doesn't know what an array is, I recommend he start a C# course first.

[burnt vapor]

Judging by the question, they have already grasped the basics. It doesn't hurt to point somebody in the right direction, especially since they're keen on learnng.

[chrome scarab]

No, just learning what arrays are won't help him much.

Shouldn't he learn other things too?

[burnt vapor]

I suggest you advice them and not me

[chrome scarab]

It will be much more useful if him learn at least loops, methods and structures.

[candid oyster]

Guys no need to argue

[chrome scarab]

I'm already giving him advice, I'm just talking to you xD

[candid oyster]

thanks for the help

[chrome scarab]

u re welcome

[timber tide]

Honestly, sometimes the most mundane way is correct. However, something like a switch for cleaner code, or for larger amount of entries, a dictionary, would be ideal to grab the values you want.

[candid oyster]

Yeah, someone mentioned switched and dictionarys

Ill start learning about these

Never used them before

rn im looking into arrays tho

[timber tide]

Dictionary a little more intermediate, so look into a switch first, also look into using else/else if

[candid oyster]

I know how else/else if works :)

[timber tide]

Ah, ok just making sure your use case is correct since you're checking all values there

[candid oyster]

but thanks

[timber tide]

regardless if you found the value you want

[candid oyster]

yes, you are right

[timber tide]

you'd usually want your code to fall through once you find what you're looking for ;)

[burnt vapor]

I suggest you look into both but practically it makes no sense to use a dictionary here

[candid oyster]

okaay..

[burnt vapor]

These require a key and considering you're working with a 2d grid, nothing succeeds anything here

That's why I personally think you should use a 2d array, but see what suits you best

[candid oyster]

Im looking into arrays rn

im doing the W3 schools tutorial

[static cedar]

My god, if ur gonna do it like that, do use else keyword.

[timber tide]

looks exactly like my first tetris game I made in c++

[static cedar]

Also the 2D array is the right answer here.

I suggest using it as a Vector2Int rather than just two ints and then just myArray[vector2Int.x, vector2int.y].

[burnt vapor]

Hmmm, I should try out c++ sometime...

[timber tide]

2D array works but then you have to also check for wrapping around the indices, actually that's only relevant if you use a 1D array as a 2D array. I forget, need coffee.

[static cedar]

I think I won't, I'll try zig someday.

Also C.

[teal viper]

Also assembly

[static cedar]

Wait a sec, you don't need a collection or a chain condition for this.
This is literally just getting the coordinates to above, below, right and left.

[gaunt ice]

that why i said 'A'+1=='B'

[somber wren]

Hello guys, i just have this little part of code. But the hitpoint is always with Y = 0.5 i cant figure out why..

my plane ground is at 0, 0, 0

[burnt vapor]

Hence the 2d array

[burnt vapor]

Nothing in this question or image suggests anything that might be wrong

[timber tide]

It's part of the learning process for them

[somber wren]

this is my code xd

i dont modifiy the hit point, and it always do Y = 0.5

This a typical hitpoint

[gaunt ice]

i remember plane has no height? or you use something that has "height" eg box collider?

[somber wren]

the only thing i have on my moving player is a rigibody, and the plane has juste a mesh collider

My ground vs my spider

[slender sinew]

making a plane's collider Convex causes it to have height

look at the collider in the scene view

[static cedar]

Not even necessary I think.
This looks like a 4x4 box.
Just get 5 Vector2Int and do this mathematically.

Then check if any of the structs have a value of X or Y value is 0 or 5 which is unused or just invalid.

Idk why he needs it in the form of LetterNumber coordinates string but hopefully, that's not even necessary or just convert it into that after.

[somber wren]

oh

might have checked that box to test something, wait

thank you! i didnt know !!

[azure zenith]

Anyone?

[candid oyster]

that was just a prototype

I intended to change it anyways

[gaunt ice]

show your inspector first

[thick goblet]

I have a strange issue where my player which is a cube cannot completely freeze it's transform.position.x so when I begin moving it lets say right and he freezes on the 3rd lane he starts jittering quickly left and right by a few decimals instead of remaining 0, I want the transform to stay at 0 after each freezemovement(). What's the problem? Here is the lane movement script I made: https://hatebin.com/lkvswnoqey I might have a conflicting movement left and movement right condition

[timber tide]

I don't use RB much but usually you want to use its own methods to do stuff like freeze rotations or add constraints

https://docs.unity3d.com/ScriptReference/Rigidbody-constraints.html

something like that? I know you can freeze rotation on the rb in the inspector itself.

[static cedar]

I think it's under the rotations tab to lock RB rotation to a certain axis.

There's also another field which has static in it, it might be a dropdown, which means it can't move at all.

[slate badge]

how can i write this without getting the "Only assignment, call, increment, decrement, await, and new object expressions can be used as a statement" error.

because if I do allowjumping --; it says that the value cannot be null

[gaunt ice]

what is allowing jump

bool?

[slate badge]

a float

[static cedar]

-=

[slate badge]

what's the difference with -= and --?

[static cedar]

I'm assuming u want to subtract allowJunping by 1.

[slate badge]

yes

[static cedar]

-- means subtract the variable by 1. -= means minus equals, you need to tell what you're the variable subtracting with.

[sour fulcrum]

both are little helping things that just condense a longer thing

myValue -= 1 just means myValue = myValue - 1

myValue-- just means myValue -= 1

[gaunt ice]

=- is not -=

thers is no =- operator

[static cedar]

=- isn't valid right?

Real.

[sour fulcrum]

thank god for IDE's 🙏

[static cedar]

** and // should be a thing, it basically does nothing.

[wintry quarry]

It's "valid" but it's the same as x = -y;

[static cedar]

Seems legit.

Btw, I know basic math operations follow PEMDAS but where does modulo operator fall into?

[timber tide]

probably same as MD

i forget

[north kiln]

just google "C# operator precedence"

[static cedar]

Seems legit.

[timber tide]

PEMDAS is just our own ruleset

you can always make your own and telll everyone else they are wrong

[sour fulcrum]

i put brackets around everything just incase

never trust anybody including yourself

[static cedar]

You're trusting the brackets tho.

[sour fulcrum]

they are tall and secure math walls and they are all i have left

[static cedar]

[slate badge]

thank you both @static cedar

[echo owl]

Hi, I'm trying to make a sprite like the youtube video but when I click on chat bubble and try to make 2d object > sprite it shows more options than it does in the youtube video, any suggestions as to why?

[gaunt ice]

because your editorversion is newer

[slate badge]

can anyone explain what's wrong with this?

[buoyant knot]

i don’t see an issue.

but it does depend on other things

[slate badge]

exactly but whenever the game object touches the floor the float doesn't go to 0

[buoyant knot]

like if layer mask/collision matrix doesn’t send a collision callback

[gaunt ice]

this is trigger

[north kiln]

Go through the physics messages troubleshooting resource in the pins

[buoyant knot]

or if rigidbody isn’t configured properly

[gaunt ice]

i dont think your ground is trigger that you can pass through so you need collision

[buoyant knot]

it depends on how everything is configured.

it could be a trigger ground check hitbox, with solid ground collider

it’s hard to know without more info tbh

[slate badge]

I don't get it sorry

[buoyant knot]

i personally use oncollision so I can check normals etc, but I understand some people actually use a separate hitbox to look for ground

OnTriggerEnter only activates if you have a collider set to IsTrigger

OnCollision activates if both colliders are NOT set to IsTrigger

triggers are not solid, and never send force

[royal ledge]

https://gyazo.com/073b0f90f560f76920cd96df6843acd1
I've had this issue that sort have been on the back of my mind, Looking at other games in unity their bullet collision is perfect,
However, when my bullet hits the wall, the prefab for the explosion is a tad bit inside the wall. The prefab spawns in the middle of the bullet so technically it should be outside of the wall if the collision was perfect. The collision check is basically:

private void OnTriggerStay2D(Collider2D coll){
  Instantiate(explosionPrefab,transform.position,transform.rotation);
  Destroy(gameObject);
}

Things that i have tried.

• Set Bullet rigidbody to continous,interpolation and never sleep
• Reduced the physics time step to 0.01

I do not know what else i can do to improve it, any input is appreciated

[buoyant knot]

you can’t walk on a trigger

[gaunt ice]

yes you may have an additional hitbox to check, but in case no, use on collision enter (or attach a trigger collider hitbox on it)
the ground usually not a triggered collider

[slate badge]

ah no wonder, because when I tried activating isTrigger to the floors, the player just fell through

[buoyant knot]

anyway, the code is not the issue, depending on exactly how your collider is set up

your code is good IF you have a trigger collider under your player checking for ground

that method is kind of sus, tho, because it can lead to shitty ground detection on the edges

if both are solid, that code will not work

for ground detection, there are several methods, which you can find on youtube

[slate badge]

alr thanks

would raycasting be a better method?

[gaunt ice]

compuational time less than overlap but you may get wrong result

[ornate sparrow]

I have 1000 objects and 1 prefab, I want to take the prefab and replace all the objects with this prefab

so that there is a blue prefab on stage

How can I do that?

[buoyant knot]

you use code to instantiate the prefab on those objects’ spots, and destroy the other objects

[ornate sparrow]

yes, but I just get a gray clone, and I want this to be a prefab on the stage so that I can further override all these objects together

[buoyant knot]

Casting the whole collider is most accurate imo, and also most expensive. The cost still is minimal, and very worth for physics that actually works consistently

I would probably make a component that allows a given object to replace itself

responsible for getting together the information of what to replace and all that

like position, scale, rotation for the new object. any parameters for the new object

then one singleton that has references to all hangars, and can tell them all to swap

or rather, a singleton that invokes an event, all hangars have that monobehaviour subscribe to that event, so when the event is triggered, they all swap

make sense?

[royal osprey]

Hello guys, interesting
I coded a scripts what has CrossFade functions
like CrossFade State_Changer/death and i have a rare bug
what if CrossFade State_Changer/death (one of this) started and then another... it's just buggy and like 1 in another....
or CrossFade death started but he doesn't change his animations....

[ornate sparrow]

I have already made the replacement,I need to figure out how to make this object so that this object is a PREFAB WITH THE POSSIBILITY OF OVERRIDE BLUE on the scene

[candid oyster]

Okay, I did it with the 2d array

it works

and its better then what I had before

so Ill leave it like this

[dawn sparrow]

Why does my IDE say the else is redundant when I uncomment the commented return line?

[wintry quarry]

because you can just do:

if (stuff) {
  things;
  return data;
}

container[whateverblabla]
return data;```

since there's a return in the if, the else is not necessary since control will not continue after the return

it's basically an implied else

[dawn sparrow]

Ahhhhh

Thank you, I was pretty confused

[wintry quarry]

also you can do this:

if (stuff) {
  // things
}
else {
  containterblaiblah
}

return data;```
Instead of having two returns

since you're returning data no matter what

[dawn sparrow]

true, no need for two returns

I'll do that

[burnt vapor]

Close enough, good job

[spare umbra]

I have this dashing code on my PlayerMovement script.

And I'm calling it from my PlayerInput script just like that

But when I dash player sometimes goes 3.2 and sometimes 4.8 units

Weird... How can I fix it?

I can't say it's framerate dependent because there is only 2 numbers as I said

[static cedar]

Btw, is there a reason that u need it in A3.. those stuff?

[wintry quarry]

It's possibly a framerate dependency issue and possibly related to your calculation for the velocity

1. You are using WaitForSeconds which is not going to wait a constant number of physics updates
2. where does the direction variable come from?

[slender path]

anyone know how to delay a function from happening?

[teal viper]

Call it after the delay..?

[slender path]

how do i make a delay

[frosty hound]

Use a coroutine

[teal viper]

A timer in update, a coroutine, async await, etc...

[spare umbra]

I'm setting the input vector2 here on PlayerInput script

[frosty hound]

"How do I make a coroutine"

Use code

"How do I code"

[slender path]

it is the invoke thing right

[teal viper]

No

[wintry quarry]

Are you using a joystick?

[spare umbra]

Keyboard

[wintry quarry]

Is it intentional that direction will NOT be reset/set to 0 when you release the keys?

[spare umbra]

Yes to make the player be able to dash when not moving

[wintry quarry]

also where does dashSpeed come from?

[spare umbra]

It's a float

[wintry quarry]

If that's never changing then it goes back to my first suggestion:

You are using WaitForSeconds which is not going to wait a constant number of physics updates

[spare umbra]

Is this a suggestion? :D

[wintry quarry]

It's a suggestion of the source of the error.

[spare umbra]

So what should I do?

[wintry quarry]

if you want to wait a constant number of physics updates you should do this:

int numberOfPhysicsFrames = Mathf.CeilToInt(dashDuration / Time.fixedDeltaTime);
for (int i = 0; i < numberOfPhysicsFrames; i++) yield return new WaitForFixedUpdate();```
^replace the WaitForSeconds with this

you can do CeilToInt or FloorToInt, depending on if you want 0.05 to become 0.06 or 0.04 (since your fixed timestep is probably 0.02)

[spare umbra]

I saw literally 3 tutorials doing the same code for Dashing.

Your code is working!

Bro

The way you approach the problem..

*professional ✨ *

[slate badge]

Would anybody know how when reactivating a gameobject (gameobject.setactive(true) to be at the same location as the player? Because when the game object is unactive, it's position is locked

[spare umbra]

So this code is getting the number of Physics frames during the dashDuration time. And Calling the WaitForFixedUpdate() function numberOfPhysicsFrames time

Am I right? @wintry quarry

[wintry quarry]

Unity physics happens on a fixed timestep basis, so yes we're calculating "how many fixed timesteps does our dash duration require?". Once we know how many it requires we wait exactly that many fixed updates which means that many physics simulation steps will occur.

This ensures that the velocity you assigned to your body is applied for the same exact amount of physics simulation time every time.

[nocturne delta]

so im working on a game that is based on laser and reflections and all
and i am trying to detect collision for one of my objects tagged "flower"
heres the detection code : public class CollisionDetection : MonoBehaviour
{

private void OnTriggerEnter(Collider other)
{
    if (other.CompareTag("Flower"))
    {
        Debug.Log("Laser hit a flower!");
    }
}

its pretty simple and i think its correct
but it doesnt detect it no matter what i do
any tips?

[spare umbra]

Thank you so much!

[wintry quarry]

Do both objects have 3d colliders?
Does one of the colliders have "is trigger" checked?
Does one of the objects have a Rigidbody?
Is the script attached to one of the objects involved in the collision?
Does the other object have the appropriate tag?

[slate badge]

When a game object is unactive, are it's variables static? For example can you still move it when it's unactive?

[nocturne delta]

yes
no
no i dont want them to have physics
no its not its attached to a laser pointer
yes

[wintry quarry]

• At least one rigidbody is required for OnTriggerEnter
• At least one collider with Is Trigger enaqbled is required for OnTriggerEnter

you will need to add those things for this code to work

(you can use a kinematic rigidbody btw)

no its not its attached to a laser pointer
Also OnTriggerEnter only works when attached to one of the two objects in the collision

Since this is a "laser" puzzle or something why are you trying to use OnTriggerEnter?

Wouldn't a raycast be more appropriate?

[nocturne delta]

i do have that in the laserbeam script so it would reflect by hitting a mirror tagged object

[wintry quarry]

right so why are you trying to use OnTriggerEnter here?

It doesn't seem like you have anything remotely close to the setup required for OnTriggerEnter

[nocturne delta]

this is the scene i have and the black object is the flower tagged one
it doesnt print anything in the console

[wintry quarry]

of course it doesn't print anything

as I explained you don't have anything close to what is required for OnTriggerEnter to work

I also don't see any black objects

[nocturne delta]

i tried to use OnCollisionEnter but it didnt work either

[nocturne delta]

grey*

[wintry quarry]

OnCollisionEnter is ALSO very inappropriate for what you're trying to do

you should be using raycasts

[nocturne delta]

so how should i modify the collision detector script?

[wintry quarry]

throw it in the trash

[nocturne delta]

and?

[wintry quarry]

make a script that shoots a raycast and interacts with any objects the raycast hits

[nocturne delta]

as i said i have laserbeam script which uses ray cast i dont know if its related or not

public class LaserBeam
{
Vector3 pos, dir;
GameObject laserObj;
LineRenderer laser;
List<Vector2> laserIndices = new List<Vector2>();

public LaserBeam(Vector2 pos, Vector2 dir, Material material)
{
    this.laser = new LineRenderer();
    this.laserObj = new GameObject();
    this.laserObj.name = "Laser Beam";
    this.pos = pos;
    this.dir = dir;

    this.laser = this.laserObj.AddComponent(typeof(LineRenderer)) as LineRenderer;
    this.laser.startWidth = 0.1f;
    this.laser.endWidth = 0.1f;
    this.laser.material = material;
    this.laser.startColor = Color.white;
    this.laser.endColor = Color.yellow;

    CastRay(pos, dir, laser);
    
}
void CastRay(Vector2 pos, Vector2 dir, LineRenderer laser)
{
    laserIndices.Add(pos);

    Ray ray = new Ray(pos, dir);
    RaycastHit hit;

    if (Physics.Raycast(ray, out hit, 30, 1))
    {
        CheckHit(hit , dir , laser);
    }
    else
    {
        laserIndices.Add(ray.GetPoint(30));
        UpdateLaser();
    }

}
void UpdateLaser()
{
    int count = 0;
    laser.positionCount = laserIndices.Count;

    foreach (Vector2 idx in laserIndices)
    {
        laser.SetPosition(count, idx);
        count++;
    }

}
void CheckHit(RaycastHit hitInfo, Vector2 direction, LineRenderer laser)
{
    if (hitInfo.collider.gameObject.tag == "Mirror")
    {
        Vector3 pos = hitInfo.point;
        Vector3 dir = Vector2.Reflect(direction, hitInfo.normal);

        CastRay(pos, dir, laser);
    }
    else
    {
        laserIndices.Add(hitInfo.point);
        UpdateLaser();

       
    }
}

}

do you think i should use if (hitInfo.collider.gameObject.tag == "Flower" or something like that?

[wintry quarry]

yes in this script you need to check which object you're hitting. You can check for tags or components or whatver you want.

[nocturne delta]

yeah i didnt knew sorry

[wintry quarry]

Notice how you're already doing this to check for mirrors:
if (hitInfo.collider.gameObject.tag == "Mirror")

the flower would just be a different case

[slate badge]

When a game object is unactive, are it's variables static? For example can you still move it when it's unactive?

[wintry quarry]

no variables are not "static" in that sense ever

[polar acorn]

That's not what "static" means

[nocturne delta]

oh your right forgot that
thanks for the help

[wintry quarry]

And yes "static" has a specific meaning in C# that has nothing to do with whether they can be changed or not

[polar acorn]

static variables are not "variables that don't change", they're variables that belong to a class instead of an instance. You're thinking of "readonly", and no, variables don't become readonly when an object is disabled

[slate badge]

so for example if I said that the unactive game object to have the same position as the player, if i reactivated it would it be at the position it was unactive or at the player's position?

[wintry quarry]

it would be at whatever position it was set to most recently. The active state of the object is irrelevant.

[dawn sparrow]

I'm attempting to write a function that'll print a tuple of unknown length and content types, but I don't know how to specify that with syntax

[wintry quarry]

tuple.ToString() doesn't work?

[dawn sparrow]

no way

Yeah that's what I was getting before

I want to see the individual values in the tuple

[wintry quarry]

well actually this is not a tuple odf unknown length

[timber tide]

Can't you foreach over it

[wintry quarry]

this is a Tuple of length 1 explicitly

[timber tide]

Oh yeah Tuple<T> would be a single entry does that even work

[dawn sparrow]

How do i specify unknown length then?

[wintry quarry]

ITuple

Which btw has these properties:
https://learn.microsoft.com/en-us/dotnet/api/system.runtime.compilerservices.ituple.length?view=net-7.0#system-runtime-compilerservices-ituple-length
https://learn.microsoft.com/en-us/dotnet/api/system.runtime.compilerservices.ituple.item?view=net-7.0#system-runtime-compilerservices-ituple-item(system-int32)

[dawn sparrow]

Alright I'll look into that

Thanks

So I've written my function but now I can't pass my (int, int) tuple into an ITuple param
Not seeing information on the difference between the two or if I can convert a tuple to ituple

Wait, one sec

Ahh nevermind I just wasnt reading the error properly

[wintry quarry]

yeah you've got an array there

the tuple itself should fit fine

I recommend using a StringBuilder rather than string concatenation btw. The performance will be much better

[dawn sparrow]

Yup, works now, I was just being blind lol

[dawn sparrow]

Thanks for the tip, I know about stringbuilders but since i'll really only be using the print function for debugging im not too concerned about performance

maybe i should do it anyway tho

[wintry quarry]

eh not a big deal

[hollow zephyr]

Type mismatch when trying to add a projectile spawn point to a scriptable object

[dawn sparrow]

Pretty sure editor will show "Type mismatch" for a scriptable object initialized during runtime

Think that applies to gameobjects as well but not sure

[rich adder]

@hollow zephyr are you trying to add a scene object into a Prefab or SO ?

[hollow zephyr]

An SO

[rich adder]

yea u can't do that

[hollow zephyr]

oh i see

Is there a pattern that I should be using to accomplish what I am trying to accomplish?

[rich adder]

have the spawn point on the same script that uses the SO for data

[hollow zephyr]

The issue would be that not every spell has a spawn point

[stiff stump]

GameObject tracer = Instantiate(_trail, barrel, transform.rotation);

Rigidbody2D rigidbody = tracer.GetComponent<Rigidbody2D>();
rigidbody.AddRelativeForce(tracer.transform.forward * _bulletspeed);

anyone one have any ideas why this wont move the gameobject it just stays still when it gets Instantiated the bulletspeed is 10

[wintry quarry]

transform.forward is along the Z axis (assuming a normal object orientation in 2D)

in 2D that doesn't exist

so basically you're doing AddRelativeForce(new Vector2(0, 0))

[rich adder]

maybe that can be a bool or something ? I'd have to know a bit more about your setup

[wintry quarry]

try transform.right or transform.up

[hollow zephyr]

Hmmmm, would it be a good idea to somehow get the spawn point from the parent that I am passing into the Activate() function?

The parent in this case would be the player, and the ProjectilePoint is a child of the Player, so maybe using parent.GetChild() or something like that might work?

What would you need to know from the setup? Im happy to give details

[royal osprey]

can anyone help?
https://hastebin.com/share/diqocarese.csharp
I getting an a error on
if (EnemyUnit.unit_type == 1 && ground = true)
and idk why

[wintry quarry]

I getting an a error on
What error?

[royal osprey]

The left-hand side of an assignment must be a variable, property or indexer

[wintry quarry]

Why are you doing ground = true?

that sets ground to true

use == for comparison

[rich adder]

when do you call Activate, sure you can pass it thru that

or directly reference the transform

[royal osprey]

uh, stupid moment

thanks you

[gaunt ice]

your code is doing (some bool&&some bool)=some bool, but the result of && operator is unassignable, so the compiler give you this error

Hey, how do I fill a 2 dimensional array with game objects?

a normal array works normaly, I see it in my inspector and I can fill it up

but my 2 dimensional one doesnt even show up

[rich adder]

yeah unity doesnt serialize multi dementional/2d array

[candid oyster]

Hmmm, so how do I fill it up then?

[modest dust]

Put an array into a struct and make an array of the struct

[candid oyster]

alright, thank

s

[fallen snow]

super simple question: how do I group things in the hierarchy

?

[frosty hound]

Depends what you mean by group.

This isn't a coding question either.

[fallen snow]

omg

[rich adder]

also you would use a gameobject to nest into to create a "group"

[frosty hound]

Everything in the hierarchy has a parent. If you put something inside of another object as a child of it, it will be attached to it.

Then you can collapse the parent object

[fallen snow]

I guess I'll just go the long way and create an empty game object and but everything inside my little group as a child

[polar acorn]

What would you expect to be the "short way"

how else would you group things

[fallen snow]

I mean on 3D modeling software you can use ctrl+G and it just groups things together and makes a folder. was just assuming unity had same functionality

[polar acorn]

Select multiple objects, right click, create empty parent

[modest dust]

Isn't an empty gameobject basically a folder

[frosty hound]

You can move a bunch of objects into a new parent by multiselecting them and creating an empty from the right click menu

[rich adder]

yes hierarchy has no concepts of folders, they're all gameobjects

[modest dust]

Yeah

[fallen snow]

thank you

[modest dust]

I suppose you could get a package to make "header" folder but it's still a gameobject

[candid oyster]

what exactly do structs do?

[modest dust]

better than nothing tho

[candid oyster]

I dont really understand them

[rich adder]

they're like a class, but they're value types

[slender path]

I am trying to get the point on the mesh but when it tries to get the point of the mesh on a different one that is not the middle one it then says nope

Anyone know how to fix this?

[modest dust]

google structs, also as navarone said

[rich adder]

@candid oyster also you'd have to add [Serializable] above it to see it in the inspector

[candid oyster]

above the struct yes?

[rich adder]

yes

[rotund hull]

how can i make a background that is infinite so where ever the camera goes the background is still there

[candid oyster]

alright, thanks

[modest dust]

just move the background with the camera

[polar acorn]

Or just use a skybox

[modest dust]

^

[rotund hull]

well i still want the backgrond to move bc its space

it is 2d

[modest dust]

still same thing

[rich adder]

something like this should work

public class Awesome : MonoBehaviour
{
    public GameObjectArray[] GameObjects;
}

[Serializable]
public struct GameObjectArray
{
    public GameObject[] objects;
}```

[candid oyster]

thanks, this will help

[modest dust]

move the main anchor, and move the background attached to it separately

[slender path]

I am trying to get the point on the mesh but when it tries to get the point of the mesh on a different one that is not the middle one it then says nope
Anyone know how to fix this?

[rotund hull]

?

[modest dust]

Have an empty GO with the background attached to it, move the empty one alongside the camera and do whatever you want with the background itself

[candid oyster]

Dont I need to put a comma in between the []

?

[modest dust]

or just spawn/despawn backgrounds as you move

[candid oyster]

I thought that thats how to make it 2 dimensional

[rich adder]

no because that defeats the whole point of doing this

[candid oyster]

oh

okay Ill try to mess around with it for a bit too hopefully understand it

[rotund hull]

i tried to do that but i dont know how

[modest dust]

have a grid-like background system and track the camera position

spawn backgrounds in the camera range and despawn when they get out of range

[rotund hull]

ok but when i spawn a back ground how do i know where to put it next to another background pieace

[candid oyster]

stupid question. Is the struct supposed to be in a different script? I never messed around with classes

[rich adder]

the struct can be either in the same script or separate file

just declare it outside the Mono class

[candid oyster]

its giving me an error that it doesnt understand the [serialized]

[rich adder]

you need to add using System;

at top

[candid oyster]

oop

alr

[rotund hull]

or is it fine to have a lot of background that all have their sprite renderer disabled and when you move to it it gets enabled

[gaunt ice]

in c# you have two ways to create 2d (or multi dimensional) array: [,] and [][] (list of lists is just a wrapper of second one), unity wont serialize first one but with some trick it can serialize second one

[rich adder]

otherwise if you really wanted to create a [,] and see it inside the inspector , you'd have to make a custom inspector/property drawer

[candid oyster]

okay

I got a really wierd error

"Unsupported type vector"

[rich adder]

show whole error

[candid oyster]

thats litteraly it

[polar acorn]

Look at the actual error

[rich adder]

you expand the console and look more details

[polar acorn]

not just the first line

[gaunt ice]

try restart editor

[candid oyster]

oh

wierd

I just pressed start

and its gone

[rotund hull]

how can i make a background the is infinte so where every the camera is the background is there

[polar acorn]

Skybox

[rotund hull]

ok i will try that

[fallen snow]

Hey! actual coding question this time.

// The key to press to create the objects/projectiles
private KeyCode keyToPress = KeyCode.Space;
how do I make it so instead of a key being pressed, it's just constantly shooting.

private ?? ?? = true;

[polar acorn]

You'd have to look at where the shooting actually happens

[gaunt ice]

it is just a variable, nothing to do to make you continously shooting

[polar acorn]

instead of where you define which key does it

[candid oyster]

so how exactly is this array 2 dimensional?

[rich adder]

also !code

[polar acorn]

It's an array of an object that contains an array

it is basically an array of arrays

[fallen snow]

oh so maybe I can make a variable bool which I can bind to where it actually shoots

[polar acorn]

Which is not technically 2D, but close enough that can still be serialized

[candid oyster]

ohh

[rich adder]

doesnt look like your ide is configured either.

[candid oyster]

so lets say I want to have a 4x4 2d array

so it basicly makes 4, arrays each habing 4 slots

[polar acorn]

You would have an array that contains 4 of this object that each have an array of length 4

[fallen snow]

I literally started coding yesterday 😭 plz

all good, but you you dont want to be coding without a working ide

[fallen snow]

Idk what ide even isss

[rich adder]

visual studio

your code editor

[candid oyster]

so how do I fill it up with my game objects? in my inspector I just see it like a normal array

[cosmic plover]

You add the arrays to it through code in a loop. Or at least that's how I do it.

[polar acorn]

You should be able to expand the inner element and add your objects to it

[candid oyster]

wait a moment...

[timber tide]

Technically you can make a 2D array out of a single array but it's a bit more mathy

using the 2D array data structure makes it a bit easier though

[candid oyster]

now its working, thanks

[candid oyster]

yes, I did that but it doesnt show up in the inspector then

[timber tide]

Yeah, unity doesnt like those

[stiff stump]

Im having an issue with trail renderers and sorting layers
so i have my gameobject over the top of a tilemap which the sprite its self is visable but the trail renderer isnt visiable while over the tilemap
they are both on default layer and the trail renderer is a layer above the tilemap but still not visable

[cosmic plover]

No you can't. It'll just be one big array. You'd have to code in a way to separate them right?

[gaunt ice]

there is no multi dimensional array in computer memory

[modest dust]

not a good idea

[timber tide]

you can have as many dimensions as possible in a 1D array, but it's up to you to handle the navigation of it all.

but yeah in memory it's just a straight line down ;)

[cosmic plover]

@timber tide Yeah but then why use bools when you could just use ints? Why use anything that makes it easier?

[fossil tree]

hi, little question how i can show and hide my canva in code????

[gaunt ice]

setactive

[timber tide]

same reason people use C still

[fossil tree]

k i gonna look that tysm

[rich adder]

canvas.enabled = false / true

[fossil tree]

i need import the canva before or something like this?

[rich adder]

you'd beed a reference to it regardless

if type is Canvas you use .enabled

if you use GameObject type, then use SetActive

[fossil tree]

oh ok its a canvas for me

[polar acorn]

Multidimensional arrays are stored in memory as single-dimensional arrays anyway

[rich adder]

just [SerializedField] private Canvas canvas
and drg the component inside

[polar acorn]

You can do math to get the 1D index given the X,Y coordinates

[fossil tree]

i need make someting like that ?

Canvas canvas = canvas.GetComponent<Canvas>();
            canvas.enabled = !canvas.enabled;
            canvas.enabled = true;```

[rich adder]

no

[rotund hull]

but how would i know where to respawn the background

[rich adder]

#💻┃code-beginner message

[polar acorn]

If you already have a variable canvas, why GetComponent from it

Just use the variable you already have

[fossil tree]

idk its just a random thing i find in google xd

[candid oyster]

how do I access the arrays now?
For example before in my 2d array I just did:

Array[Value1,Value2];

[modest dust]

based on the camera position -> transform the cam pos into grid coords and spawn background in range of these coords
