I have no idea what you've written and I cannot see your screen.

[sacred orbit]

the only thing I think would cause this issue

is that it's not in a coroutine

[swift crag]

heldItem is an argument to the method

you are setting that local variable to be null

[short hazel]

IDE not configured...

[swift crag]

that does nothing to the thing you passed into dropHeldItem()

[robust condor]

Ye that is not a variable

[slender nymph]

there is an awful lack of syntax highlighting for unity's methods and types. get your !IDE configured

[eternal falcon]

[short hazel]

(this step is required to get help here)

[sacred orbit]

I configured it the way it said

this is just how it ended up

[primal dirge]

Hi!

[slender nymph]

you either missed a step or you need to regenerate project files

[swift crag]

if it didn't work, ask for help instead of just ignoring the problem

[swift sedge]

the most important thing you need is intellisense

[robust condor]

@sacred orbitYou're also approaching the problem incorrectly. What you are holding in your hand should be a variable in your character class, and set that to null

[sacred orbit]

thank you, this worked

[swift crag]

now go fix your code editor before you do anything else

[hidden sleet]

Does this 'unity script' thing at the top mean my one is configured right?

[slender nymph]

yes

[swift sedge]

also MonoBehaviour is highlighted

[tacit topaz]

and it turns out you fix this by making sure to serialise a class instead of the list itself. Works now even if it's a bit messy

in case anyone else had a similar issue

[tribal zephyr]

should i join a game jam?

[queen adder]

guys i can teleport somwhere in a scene but i want teleport to another scene to a location that i assign how can i do that

[swift sedge]

yes

[tribal zephyr]

when can i start

[robust condor]

@tribal zephyrYou dont need our permission

[swift sedge]

read the jam rules

[tribal zephyr]

when will it happen

[robust condor]

When it happens

[tribal zephyr]

how to check

[swift sedge]

itch.io -> jams -> select a jam

[tribal zephyr]

okay thanks

[hidden sleet]

So I've got a dictionary that's supposed to link an inventory item slot from an inventory container full of items, to a game object that represents that slot as a UI element on the screen. When the scene loads it looks at the inventory, creates the UI elements and creates the entires for the dictionary so i can later change the details of the ui element when the item details change, and upon loading the dictionary seems to be getting the right value and properly generating the key value pair.

UpdateDisplay is then called when a new item is picked up, but now the values of the dictionary are just null. And I've still got no idea what is causing it. had to develop a messy workaround before but its come back to bite me in the bum

and so an exception is thrown saying it's been destroyed, but between loading the scene and updating it nothing actually changes with the gameobjects

[slender nymph]

is itemsDisplayed the dictionary you are serializing to json?

[hidden sleet]

no that's something else sorry. I'm serialising this container of slots, the dictionary should just stay in the scene

[slender nymph]

instead of sharing these tiny snippets of code that aren't showing the full picture and are screenshots that discord is cropping making it incredibly frustrating to read, you should share the full !code correctly

[hidden sleet]

yeah that's a bit nicer https://hastebin.com/share/dehuguhixa.csharp

[slender nymph]

notice how you call DisplayeInventoryOnLoad then immediately after that you assign a new Dictionary to itemsDisplayed

you're doing it backwards

[hidden sleet]

just spotted that after posting, will see if that resolves anything

[slender nymph]

and for future reference, always start with the first error in the console. it usually causes subsequent errors

well it should considering you would have received a NullReferenceException in DisplayInventoryOnLoad

[hidden sleet]

in this case the two dictionaries after the load was an attempted solution on my part, seeing if I could make sure that the dictionaries are re written on load. I still had this issue a few days ago, but it was just the values that were null, not the dictionary as a whole

[slender nymph]

then where do you assign to the dictionary before Start is called?

[gilded sinew]

does anybody know code for getting all the users in a list from firebase realtime database using REST API

need to get list of these

[hidden sleet]

this is what I had before, just moved the new Dictionary ones down a bit https://hastebin.com/share/risujixebu.csharp With it this way round, it adds the gameobjects properly when the scene loads, but then when I go to update it's just null

as if the gameobject is deleted, but it never is

[slender nymph]

but it never is
then what is Destroy(uiObj);

[hidden sleet]

since the inventory is supposed to update, then this runs, that was initially going to be what handled removing the UI element. but since the inventory is a list, that does nothing and is never run

[slender nymph]

by the way, you know you can throw a component on those objects that has something in OnDestroy to let you know if it is being destroyed

[hidden sleet]

so just a script that posts a log?

[slender nymph]

sure

[hidden sleet]

that might be useful

I know on scene changes it should be destroyed, is there a way to check to see if one was destroyed specifically because of switching scenes to see if they are being destroyed within the same scene?

[wraith mango]

is this the dan pos inventory tutorial?

[hidden sleet]

probably

been using a fair few to get the ball rolling

don't recall the names of them

but I use them to give myself some direction on what to learn

[wraith mango]

did you have a problem where selecting things from the hotbar are inconsistent?

like sometimes it will pickup, other times not

[hidden sleet]

haven't got a hotbar, only functionality I have is clicking an inventory item to remove it

[hidden sleet]

ran it through and it only destroys the objects on scene change, as expected, no clue then why mid scene it just vanishes :/

although one ui slot seems to be destroyed twice on scene switch which I don't understand

wait is it normal for the values of the script on the prefab to change during gameplay?

that on the right reflects what I last picked up, but I didn't think it was supposed to

[swift crag]

It shouldn't. Sounds like you're modifying a prefab, rather than an instance of a prefab

[hidden sleet]

maybe that could be where the rest of the issue lies

public class DisplayInventory : MonoBehaviour
{
    public Inventory inventory;

    public Dictionary<InventoryItemSlot, GameObject> itemsDisplayed = new Dictionary<InventoryItemSlot, GameObject>();
    public Dictionary<Structure, GameObject> structuresDisplayed = new Dictionary<Structure, GameObject>();
    public RectTransform scrollParent;
    public GameObject slotPrefab;
    public List<InventoryItemSlot> inventorySlots;


    private void Start()
    {
        //Use a c# callback deligate to call the UpdateDisplay method on item pickup rather than continuous updates
        inventory.onItemInventoryAdded += UpdateDisplay;

        DisplayInventoryOnLoad();

    }


    private void Update()
    {

    }

    public void DisplayInventoryOnLoad()
    {
        /* Iterate through the player's inventory
         * Simply create an inventory element and set the count and colour to the right value
         */
        if (inventory.invContainer.Count != 0)
        {
            for (int i = 0; i < inventory.invContainer.Count; i++)
            {

                slotPrefab.GetComponent<InventoryUiSlot>().CorrespondingInventoryItem = inventory.invContainer[i];
                slotPrefab.GetComponent<InventoryUiSlot>().inventory = inventory;
                var obj = Instantiate(slotPrefab, Vector3.zero, Quaternion.identity, transform);
                obj.transform.SetParent(scrollParent);
                itemsDisplayed.Add(inventory.invContainer[i], obj);
                itemsDisplayed[inventory.invContainer[i]].GetComponentInChildren<TextMeshProUGUI>().text = inventory.invContainer[i].count.ToString();
                itemsDisplayed[inventory.invContainer[i]].GetComponent<Image>().color = inventory.invContainer[i].item.color;

            }
        }``` Since I pass in the prefab at the top to create the object, I assume me changing the slot prefab is doing that then

[swift crag]

you shuldn't be modifying the prefab, yes

you should be instantiating the prefab to get a new object

then modifying that object

And you are doing that

[hidden sleet]

just partially

[swift crag]

you're just doing it after messing with the prefab

also, instead of slotPrefab being a GameObject, it should really be an InventoryItemSlot

or..an InventoryUiSlot? I can't quite tell

[lavish tinsel]

question, why are almost all examples of MonoBehaviour classes without any input parameters - and instead they declare public variables below and empty parameter class declaration?

[swift crag]

what do you mean "input parameters"?

[hidden sleet]

sorry bout the names being confusing, it's a cobbled mess at the moment

[swift crag]

are you talking about constructors?

[lavish tinsel]

yes

constructor params

[swift crag]

You can't construct a MonoBehaviour yourself

[lavish tinsel]

ah, I see

[hidden sleet]

but since I need to change the text of the UI element that exists in the scene, I assumed i needed to hold the actual game object right?

[swift crag]

Unity constructs the object and then applies serialized properties afterwards

So you can certainly write a parameterless constructor and do stuff in it

[lavish tinsel]

ok perfect. good to know

this discord is great

[swift crag]

but:

• you can't meaningfully use it yourself
• serialized properties won't be applied yet

no prob!

MonoBehaviours can't exist on their own; they have to be on a GameObject

hence the constraint

I do often wind up writing an "init" method that feels a lot like a constructor

because Awake runs too soon (as part of Instantiate/AddComponent) and Start runs too late (on the next frame)

[hidden sleet]

oh hang on, I may have an idea

[lavish tinsel]

ok slightly unrelated question. I'm trying to understand the pros and cons of these two implementations of 2D ground detection:

if (collision.contacts[0].normal.y > 0.5f)

vs

if(collision.GetContact(0).normal == Vector2.up)

[swift crag]

The latter only works if the normal is exactly the up vector

[lavish tinsel]

i feel like #1 is superior because it can work on ramps

[swift crag]

well, within a very small margin, since Unity does that for you

[lavish tinsel]

yeah

ok, there isn't some performance overhead with number 1?

[swift crag]

nah, it's probably even faster than the second one

[lavish tinsel]

ok nice

[swift crag]

given that it only cares about 1 number

it's basically meaningless though

I would look at using Vector3.Angle(normal, Vector3.up) to get a more meaningful value, though

It's less intuitive for me to say what this means:

if (normal.y > 0.5f)

than what this means

if (Vector3.Angle(normal, Vector3.up) < 45)

[lavish tinsel]

do yall tend to use rigidBody.AddForce for jumps as opposed to rigidBodyb.velocity = new Vector2(rb.velocity.x, jumpForce);? I tried the addForce and the jumps were... "weird"?

hard to describe

[swift crag]

AddForce defaults to ForceMode.Force

https://docs.unity3d.com/ScriptReference/Rigidbody.AddForce.html

[lavish tinsel]

idk why, but my double jumps are sometimes "weak" with addforce

[swift crag]

so the force vector is interpreted as...a force

how hard you're pushing

[lavish tinsel]

I used Impulse

[swift crag]

if you call AddForce every physics update, that makes you push on an object that hard

[swift crag]

okay, that's more reasonable for a jump

[lavish tinsel]

ohhh, so if i'm descending...

the force is "cancelled"

[swift crag]

But yeah, you'll still get different behavior

[lavish tinsel]

ish

yeah that's def why

[swift crag]

You're changing the object's momentum by a fixed amount

[lavish tinsel]

yep

[swift crag]

rather than just directly changing its Y velocity

[hidden sleet]

huh, now displayInventory itself has been destroyed? but that's just the script on the Ui container. This is making me go

[lavish tinsel]

you are very helpful

[swift crag]

For a more "realistic" double jump (maybe a rocket pack), AddForce makes sense

but if you want an arcadey one, go with velocity changes

[lavish tinsel]

yeah it seems to be a little more fluid

[hidden sleet]

i'm at a complete loss :(

so evidently the gameobject is treated as being deleted, but it never actually deletes :/

[lavish tinsel]

is it possible to have the main camera follow a 2-D character with a "leash"? Like, there is an invisible box around the character and the camera moves with the player only when they are pushing against the edges of that box.

[hidden sleet]

even after logging it I can't see it being deleted anywhere

[lavish tinsel]

not sure if i need a script for that, or if I do this through the unity UI

[slender nymph]

use cinemachine

[lavish tinsel]

ah, any hint on where that is?

[swift crag]

It is a package.

[slender nymph]

it's a package. there's documentation on how to use it pinned in #🎥┃cinemachine

[lavish tinsel]

ah, that's for 2D also?

[slender nymph]

yes

[lavish tinsel]

ok cool ty

[hidden sleet]

made it so it says when the two slots where created, but even though it says right there that they've been created, still doesn't like ut

[swift crag]

well, you'd better look at exactly which line is throwing that error

[hidden sleet]

line 79, the line below this one, all because this returns null

that's all its giving me :(

[visual hedge]

Hello, trying to instantiate model and so on on UI layer.

        op.layer = 5;```
This actually does the work... for the parent. But the children all still have "Default" layer.
do I make some sort of ```foreach GameObject in Parent
 GameObject.layer = 5;?```
to get all the children to UI layer?

[hidden sleet]

also if this is a try get value, how come it's returning with null? Surely if it's null it would move on to the else portion?

[slender nymph]

i actually have an extension method that changes the layer of all of an object's children all the way down to the lowest level. gimme a sec to find it for you

public static void SetLayerRecursively(this GameObject obj, int layer)
{
    obj.layer = layer;
    foreach (Transform child in obj.transform) 
    {
        child.gameObject.SetLayerRecursively(layer);
    }
}

just drop this into a static class like GameObjectExtensions. then you can call it on any gameobject

[visual hedge]

ahaha 🙂 I am so noob that I have no idea where to find that static class

[slender nymph]

create it

[visual hedge]

oh

[hidden sleet]

I think I might just have to try a different system other than a dictionary

would it be worth simply having a list of itemSlot objects and a list of gameobjects instead?

[visual hedge]

does it also change the parent layer?

[slender nymph]

it changes the layer for the object you call it on and all of its children, grand children, etc. all the way down

[visual hedge]

kaay, seems like I did set this up, let me try 🙂

[visual hedge]

works like a dream, thank you very much!

[formal escarp]

Hey guys sorry i cant find anything like this but. Is there any website or app that makes you solve C# problems like some kind of duolingo but C# version? lol

[summer stump]

A popular one is LeetCode, and others like that. (Just google "sites like Leetcode")
There is SoloLearn which I guess is more analogous to Duolingo

Or just guides like w3schools, or microsofts tutorial

Resources pinned in #💻┃code-beginner too

[formal escarp]

thanks

[open vine]

Hey does anyone know how to repeat an if statement if somethinng is or isnt true? For example shoot a raycast but if raycasthit is null then repeat the raycast

[robust condor]

Make a loop

[summer stump]

Just a loop that breaks when successful I guess
Like a coroutine with a while

[edgy fox]

can you use a 2D box collider in unity 3D?

also is it possible to shoot a raycast and have it pass through all colliders that don't have a specific tag?

for example pass through everything with the "Wall" tag and only stop if the raycast hits a collider of an object with the "Player" tag

[robust condor]

Yes the raycast has a layermask parameter

[edgy fox]

thanks

[visual hedge]

how do I find the only child of gameobject without knowing it's name? 🙂

[summer stump]

GetChild(0)
Wait, gotta look up the correct syntax

Edit: fixed

[visual hedge]

thank you very much

[edgy fox]

objectName.transform.GetChild

[summer stump]

Ok cool.
That was right
https://docs.unity3d.com/ScriptReference/Transform.GetChild.html

[edgy fox]

and you can use GetChild(i) in a for loop to iterate through children

[summer stump]

@visual hedge Oh, no it wasn't. Parens, not square brackets. Like caprisun said

[edgy fox]

for example this is from a for loop that does an operation on every child except the "Frame" child

[visual hedge]

perfect, thank you

[summer stump]

Since they said there is only one child, they can just pass 0 instead of looping

[edgy fox]

oh yeah true\

so if I do a raycast like this, does it ignore everything except for objects with roomMask or does it ignore everything with roomMask

[summer stump]

The former. Only hits things flagged in roomMask

[edgy fox]

alright and how do I add roomMask to something

[summer stump]

roomMask is like a list of layers (it is a series of 32 bits that act as true false flags for the 32 available layers).
I would just make a Layermask variable
[SerializeField] Layermask roomLayer;
and set it from the inspector.
Whatever layer you want to capture can be selected. More than one too
Or you can invert it to only NOT hit the given layers with ~roomMask

[edgy fox]

wow that was easier than I thought

I had it already added a serializefield I just hadn't checked to see it was a simple dropdown

[summer stump]

Definitely. They are intimidating at first, but very simple and powerful

[edgy fox]

honestly not even intimidating

how do I outline a blank GameObject's hitbox for debug purposes

I have a blank GameObject on each corner and each one should have a 2D BoxCollider but I want to visually confirm size and location

collider does not create collision shapes?

[rocky canyon]

it should show green bounds if ur gizmo's are turned on in the top right corner

[normal mango]

following a tutorial and am getting this error while they arent, even copy-pasted their provided github code and still doesnt work, any suggestions?

[rocky canyon]

#💻┃code-beginner message

• should even show in the game window if you enable its Gizmos

[edgy fox]

yeah got it to work

have to click on the object in inspector

[rocky canyon]

yup yup

[edgy fox]

is there a pause keybind?

[rocky canyon]

P i think

[edgy fox]

I have a GameObject that only exists when I hover over something

[rocky canyon]

alt + p

or ctrl + p

[edgy fox]

thanks

[rocky canyon]

its something like that

[rocky canyon]

you're using it like a boolean..
unless IsPointerOverUIObject() is of type bool it wont work..

a void IsPointerOver() will not work.. b/c it doesn't return a bool

public bool isPointerOver(){
//code
bool newBool = true;
return newBool;
}

something like this would work.. b/c when you call isPointerOver() its returning true in that little sample code..
so it would work in your code b/c it basically would read..

if(true)
{
..blabla
}```

the github i found shows it as a bool

you got to set up the entire system, b4 it would work like its printed on the github..
in his InputManager script it's all setup like it should be

if ur not finished with InputManager or have changes it could error like you see now

[normal mango]

yup it was wrong in input manager, thanks

[wise oyster]

Hey guys I've made a settings scene with UI, etc. Now I'm not sure how to make the variables save to work in other scenes. Is this a feasible approach? like do people usually make a scene just for settings

[rocky canyon]

you can sure.. or just a gameobject u enable and disbale

look into JSON or PlayerPrefs..

PlayerPrefs is easier.. not as robust.. and used for things like settings

[ionic zephyr]

why does my game stop once it executes

[summer stump]

Once it executes what?

[ionic zephyr]

once i press play

[summer stump]

Infinite loop?

No idea with so few details

[ionic zephyr]

i press play and the game stays like this

[summer stump]

Infinite loop

Did you write "while" inside update anywhere?

[ionic zephyr]

no

[summer stump]

Ok, well its just guesses until you provide your code. Whatever changes you made before it started happening.

Is there a "while" ANYWHERE in your code?

[rich adder]

if you have an error and have Error Pause on it will hapen

[wise oyster]

thank you 🙏

[rich adder]

show the console if paused

[ionic zephyr]

Thanks a lot!

[rocky canyon]

thats the default, correct?

[rich adder]

iirc yes

[summer stump]

That should have been super obvious, so i discounted that as the reason haha 😂

[rocky canyon]

depends.. i asked if its default b/c i had a problem like that when making my loading system.. when my game loaded in it would just Stop... i had some NRE's in the console.. but thats common sometimes for me as i work thru things..

and thats what it was.. i sat there looking at the NRE for 30 min or more.. and still didn't connect the dots

lol 😄

[summer stump]

Fair lol

[rocky canyon]

an NRE? pft, I got bigger fish than that to fry

i gotta fix this other error..

NRE laughs in "Other Error"

[robust kelp]

im making an fast pace fps game like ultrakill and i dont know whats better for maintaining movement speed mid air character controller or rigid body

[rocky canyon]

this also screwed me.. there used to not be that dialog message there in the console when u had a search term in there...

i accidently put something in there once while trying to look thru my project folder.. didn't realize it was there.. and my errors completely wouldnt show up

[rocky canyon]

thats just a small bit of the puzzle.. the answer tho would be Rigidbody..

[edgy fox]

how do you log what a layermask's name is

[robust kelp]

thats how i thought

[rocky canyon]

the whole thing screams Rigidbody tbh

[robust kelp]

im stuck on this shit for past 2 weeks

[rocky canyon]

https://docs.unity3d.com/ScriptReference/LayerMask.LayerToName.html

[edgy fox]

thanks

[rocky canyon]

never used it before tho..

what if ur layermask has 2 layers ticked?

[rocky canyon]

just a spam deterent... for like when people use ^ to point to a message above you

add a few periods at teh end.. 🙂 lol

[edgy fox]

yeah

[hollow slate]

They all have ups and downs. Unity's own controller does come with ground detection and stepping up stuff. That stuff is horrible to code yourself.

It's true that it does feel quite a lot like a rigidbody-type movement. Be aware that you can achieve the same movement in both paths though.

[edgy fox]

I can say thanks but not thanks*

[rich adder]

you keep console window in a separate tab? 😮

[rocky canyon]

i keep it docked down here

but sometimes i keep it expanded on 2nd monitor..

i still don't know the most performant layout LoL

[hollow slate]

game view getting no love :(

[rocky canyon]

just kinda wing it

is there anything special i need to do for mobile..

if i want my game to be landscaped?

i just design it in that orientation i assume.. not so sure tho.. tbh

also i guess i oughta just look up some starter stuff.. no clue even how to get Unity Remote to work..

[edgy fox]

if I just remove the layermask, this works fine but for some reason if I add the layermask in the raycast none of the if statements conditions are fulfuller

[rocky canyon]

and sending an APK over my phone to test all the time sounds horrible

did you click the layers you want inside the Layermask variable of the inspector?

[edgy fox]

yeah they are all the right ones

[rocky canyon]

and the things ur targetting are set to that layer?

if you use a layermask in ur raycast it'll only detect things on those layers..

[edgy fox]

for some reason the debug.log is outputting Default

which isn't even an option in the switch statmente

[rocky canyon]

thats because ur debuggin LayerMask

thats a TYPE

its not the layermask u created

[edgy fox]

wow

[rocky canyon]

that would be layerMask

[edgy fox]

its still the PMs and I just did that

[slender nymph]

if you want to test a build you can always use an android emulator on your pc, then you wouldn't have to constantly be sending the build to your phone

[rocky canyon]

thanks for the advice, i'll look into that

finally got my first phone with a Gyroscope sensor..

figures its about time to do some Mobile Developing

[edgy fox]

wait wym I'm debugging LayerMask

I thought LayerMask.LayerToName() outputs the layers name

[rocky canyon]

you see here?

you would debug mask.LayerToName()

b/c ur LayerMask is called mask

it isn't called LayerMask

LayerMask is the type..

[edgy fox]

wait is that my code

[rocky canyon]

no

its from the unity docs

[edgy fox]

wait I'm confused what is the syntax to debug.log a layer's name

[rocky canyon]

think about it ^

like here.. if u want to move the myTransform's position

you type myTransform.position =

you dont type Transform.position =

your setting the position of a Transform thats called myTransform

you don't set the position of the type that is Transform

public LayerMask myLayerMask;

if your doing anything to this variable it would be myLayerMask.whatever b/c ur modifying the Instance of a LayerMask..

ur not trying to modify the main definition of what a LayerMask is

[edgy fox]

oh I thought LayerMask.LayerToName() was a function of the LayerMask class

that outputs the name of the layer as a string

[rocky canyon]

yea, LayerMask is what type goes there..

it could be anything.. thisLayer.LayerToName(); or myLayer.LayerToName(); or.. aReallyLongStupidNameForASimpleLayerMask.LayerToName()

etc

[edgy fox]

well the index of the layer as an int

[rocky canyon]

a LayerMask is a number

even tho it represents a Layer

just how Layers work

[edgy fox]

oh yeah layer 0 = default

[rocky canyon]

like if you want it to print out all the names of all the layers in that mask

idk how to do that

[edgy fox]

I just want to know which layer that variable is set to

ensuring I am filtering the correct layer

[rocky canyon]

can't u just peak at it in the inspector?

it shouldn't be any different than what u have selected in the Inspector..

unless you manually set the layermask in ur code somewhere

[edgy fox]

oh yeah I can serializeField it

something is setting the LayerMask to Nothing every single frame

what really confuses me is my serialized fields arent showing up

in the inspector

[rocky canyon]

ya, that shouldn't happen.. when u set the layermask and press Play it should remain how u set it

unless ur code is changing it somehow

[ionic zephyr]

https://hastebin.com/share/kiyizuzuji.csharp https://hastebin.com/share/usavasejef.csharp these are my two scrips, NullReference on the Start of the Second Script pops up

[rocky canyon]

a static variable doesn't work like that

[edgy fox]

my code is changing it via switch statement but the only outputs are wallMask and roomMask nad Default

not nothing

[rocky canyon]

pretty sure u can't Serialize it

[edgy fox]

oh yeah I made it static

[rocky canyon]

https://docs.unity3d.com/Manual/layermask-set.html#:~:text=If you want to convert,that represents the single layer.

setting LayerMasks are some kinda voodoo that I never learned

i normally just set up a couple of masks depending on what i need and just use those different masks in code..

rather than trying to change the layermask at runtime. by using bit shifting

or w/e that magic is

[hollow slate]

masks are bitmasks. Binary operations lite bit shifting work on 'em

[timber tide]

missing out on bitwise enums so you should learn

[rocky canyon]

pretty sure ur error is in Awake

and not in start.. since ur start block doesn't have any code in it

[ionic zephyr]

I had this error begore Awake

[rocky canyon]

i think its how u try to make it into a singleton

how? Awake happens before Start

ahh its ur 2nd script

its probably trying to access the GameManager Singleton b4 it gets set up

[hollow slate]

change the order of execution so that the singleton is first.

[rocky canyon]

^ this is a good idea

[ionic zephyr]

But Singleton is made in the Awake already, which is before Start

[rocky canyon]

yea, but its a Start from another script.. not the same script..

if u were accessing it in Start of it's self.. then there would probably be no issue

[hollow slate]

all Awake run before any Start in the scene. If you're sure you're only interacting with the singleton in Start, then you should be fine.

[rocky canyon]

if (instance != null)
        {
            GameManager.instance = this;
        }
        else
        {
            Destroy(gameObject);
            DontDestroyOnLoad(gameObject);
        }```

are u sure this is correct??

if instance is not null.. then set it? if instance is null, then destroy yourself?

so... if instance doesn't exist?

destroy the thing that sets it up?

[ionic zephyr]

Oh my gof

[hollow slate]

brotha'

[rocky canyon]

👍 lol

im soo used to Singleton errors being execution timing stuff like LEO mentioned

you threw me a curve ball with the bassackward if statement

[ionic zephyr]

thanks a lot

[rocky canyon]

np

yup, Layermask.NameToLayer() eludes me..

no clue how it works..

    public LayerMask clickable;

    private void Start()
    {
        Debug.Log($"The layermask you defined is: {LayerMask.LayerToName(clickable.value)}");
    }```
like I can set this up... and,
- If I have (one) layer selected.. it debugs the name of the layer directly below it.. 
- If I have (more than one) layer selected.. it debugs nothing.. 

sooo... not sure how you'd get that to list out the Name's of the layers selected on that LayerMask

[timber tide]

could make your own method for that

[rocky canyon]

yup im going to need to now..

😅 tinkerer's mind n all

[timber tide]

not too sure why single layer print values would be off though

[rocky canyon]

not sure to be honest

i could probably just (value -1)

to get a single layer.. but now i just wanna show all of em.. but thats perhaps a different day side-project

[wintry quarry]

Layer indices are not the same as layer masks

[rocky canyon]

ahh, that makes sense

[wintry quarry]

LayerToName operates on a layer index which is a number 0-31

Layermasks are bitmasks

They aren't interchangeable

[rocky canyon]

well TIL (a little bit more) lol

i always learn a bit when talkin about layers and layermasks

haha, a bit more.. snare drum

found what looks like a good little explaination

shall read and learn something hopefully

wait.. is binary 1:1 for addition and subtraction? so the binary of 1 + 2 = the binary of 3?

👀 holy crap, did not know that tbh

wait, this may or may not be true, let me do a quick test lol.. bitwise operators and bits in general make my head hurt

once u post it up im sure someone can help ya out.. common thing people say around here is don't ask to ask..

just ask

ahh there they are 👍

[past brook]

how do you check for a collider on the same object that the script is running from, I have 2 colliders on a object, one for collisions and trying to get one for jumping. I am unable to figure out how to find it

[rocky canyon]

float[,] heightMap = this.noiseMapGeneration.GenerateNoiseMap(tileDepth, tileWidth, this.mapScale); so this doesn't return anything?

[wintry quarry]

Binary is a different way of writing numbers. It doesn't change anything about arithmetic. 1+1 is still 2, 2+2 is still 4 and so on

Now there are other types of arithmetic you can do with it like bitwise operations

But every number in your computer is ultimately written in memory as binary

[rocky canyon]

and its safe to assume it doesn't convert them back and forth to do calculations

[wintry quarry]

It doesn't

[short tusk]

No sorry, let me rephrase. In script b's BuildTexture function it doesn't see noiseMap as a variable which should come from script a.

[rocky canyon]

starting to get it

[wintry quarry]

It only gets converted to decimal generally if you do like ToString()

[short tusk]

I am bad at questions sorry

[rocky canyon]

no worries, alot of people are

lol

[rocky canyon]

you can use a GetComponent<TypeOfCollider>

that will try to find that type on the same object as the monobehaviour

or if its a child object or something theres functions for that too.. such as GetComponentInChildren

[true pasture]

im trying to capitalize after a space in this function. Am I close or is there an easier way to do it?

(I dont want to use the Name option in textmeshpro)

[rocky canyon]

string newString = System.Globalization.CultureInfo.CurrentCulture.TextInfo.ToTitleCase(myString.ToLower());

try this on for size

may fit ur needs, may not tho if you only want it after spaces

[cosmic dagger]

do you know what myStats.inputField.text[-1] returns?

[true pasture]

a char of the last index

which im trying to figure out how to work with

[bright zodiac]

use TextInfo.ToTitleCase instead

oh you got it already

[true pasture]

this works, is this how I should use it?

[bright zodiac]

var txtinfo = CultureInfo.CurrentCulture.TextInfo;
Debug.Log(txtinfo.ToTitleCase(myText));

[rocky canyon]

have you done any Debugging? i think that questions over my pay-scale..

can you debug the values at the end of the function to see what its coming up with? maybe work backwards from that..
like you could Debug the noise float after u set it..
also debug the noiseMap value before u return it. just to maek sure everythings working like u expect it to?

or ask again later i guess when theres more activity of some better coders lol

[bright zodiac]

yeah, correct

[rocky canyon]

i mean newString is relative.. u can call it anything u like.. but yea.. looks fine.

[short tusk]

Trying but this tutorial might just be not so good tbh.
I can kinda descibe the problem better, it seems the variable noiseMap is not global/public i just dont know why. Still appreciate the help!

[cosmic dagger]

no, -1, is the index you're attempting to grab. that would cause an error . . .

[true pasture]

yeah I get its a syntax error, I just meant it as pseudocode tbh (using python brain)

[rocky canyon]

care to share the tutorial you're following? it may not be the best way.. sometimes they're not. but if its a relatively older tutorial and hasn't been taking down.. then it most likely will work

[bright zodiac]

btw you don't need .ToLower there the ToTitleCase will reformat it anyway

[short tusk]

ohh those are always fun..

Sebastian Lague did one on youtube.. its a Long series.. but even his has little errors here and there.. and u have to skip back and forth from video to video. to gain enough context to get it working correctly

tough system to get working flawlessly

oh yea, he charging for courses.. im sure thats a decent tutorial.

Yeah its why im inclined not to give up cause its been a bit now and for something that seems so simple it feels user error to me

Was gonna look at another but if I do it will be tomorrow I dont have the energy tn lol

[rocky canyon]

if u get stuck, dont throw it away. just save it where u are.. move on to something different.. give ur brain a relax and come back to it..

sometimes it just takes a breather to see a mistake you've overlooked countless of times

i got some work to do.. but imma bookmark this page and skim it when i get some time.. i'll give you a ping or something if i find anything wrong... but im betting its just something small thats been overlooked

Oh for sure wont throw it, and I much appreciate that thank you!! Absolutely no rush to get back to me on this!

[minor cloud]

hey there. Im making a 2d top down space game. And I want some astroids going about in the background. What is the most effective way of moving meshes from a to b. Performance wise.

[frosty hound]

How many?

[minor cloud]

Well, that depends. But Im aiming for about 250

[frosty hound]

Moving them with translation isn't going to let them be physics reliable, and that many rigidbodies should be okay but you'll likely have a lot of other things too.

Could consider DOTs though for the asteroids

Then you can have as many as you want without much worry

[minor cloud]

Without physics it would be a lot better wouldnt it?

[minor cloud]

What is dots?

[frosty hound]

I'd imagine you'd want some physics on asteroids, if you intend on hitting them?

https://unity.com/dots

Simply put, it lets you have a lot of stuff

[minor cloud]

No I have that in the foregorund. I want them to be in the background for aesthetics

[minor cloud]

This will prop be it

[frosty hound]

Then particles could also work

[minor cloud]

Is that more efficient than dots?

[frosty hound]

Impossible to say

But VFX graph allows for millions of particles, more than enough for what you'd need

[minor cloud]

I see. Thanks for the info. Ill have a deeper look into dots for now. It looks quite promising

[timber tide]

without physics: vfx graph
with physics: probably dots

probably just wanna use vfx graph it sounds like

[minor cloud]

Yeah, but dots seems not very heavy. So the little astroids in the back actually colliding would be very cool. Osteel just opened a new door for me

Can dots be multithreaded easily? Or does that take a hole new mountain of custom work?

[bright zodiac]

you can do gravity force + collission operators in vfxgraph for your physics simulation

and they made gpu-instancing works in 2022 lts

[minor cloud]

Sorry, what does that mean?

[bright zodiac]

https://docs.unity3d.com/Manual/GPUInstancing.html

[summer stump]

Dots is a term for multiple packages. It is the Data Oriented Tech Stack. It includes Jobs which are easily multithreaded. It also includes ECS, which allows highly performant code with lots of entities, but is not required to use jobs (but is probably applicable here, unless you want those entities to collide with gameobjects too, in which case it may be too much work to be worth it)
Also includes the burst compiler and some other packages to support those three

[timber tide]

Is there particle to particle collision support? I thought it's only specific to their AA box and collisional plane

[calm pawn]

How do I make a object point where the controller joystick is pointing at

[oblique ginkgo]

wow now 2 people have said that

[oblique ginkgo]

i mean, yeah
its a general rule here and its in #854851968446365696 so youre gonna get multiple people telling you the same thing

[calm pawn]

if you had seen both posts that you should know someone else already said it

[oblique ginkgo]

to answer your question

grab the vector for the joystick direction

grab the position of the object youre making look at joystick

oh right 2d or 3d

because you essentially add the vectors to create a point that it should be looking at

then either use transform.LookAt or calculate the angle

Hello!
This is my first code and I need help with two things...

1. I know the code is bad and could be simplified, so could someone help me do that?
2. How can I make sure that the images and numbers are remembered when changing scenes?

https://hatebin.com/kghyhqqaiv

[oblique ginkgo]

what images and numbers are you trying to remember

[unborn wasp]

maybe im gonna show it

[oblique ginkgo]

because you can either dontdestroyonload the gameobject which would make it exist in all scenes, write a save system or use playerprefs

[unborn wasp]

When i change scen i want after back see Monster name : Nekker and number 18
When i back to this scene i just see number 0 and white screen

[unborn wasp]

can u help me with that?

[cosmic dagger]

this is a summary, but should give you an idea. you need to create a save system to store the current card and its stats. you will save the currently focused card when that scene exits (and a new one is loaded). when that scene is loaded, you will load the save file and assign the stored card to the active (focused) card . . .

[unborn wasp]

I guess it might be related to what you're talking about, but I'm on Code Beginner for a reason—this is my first project, and I'm completely lost in this. What you're saying sounds like black magic to me. So, would you be able to help me with this? It's literally the last piece I need to start working on expanding further parts.

[cosmic dagger]

can't help too much right now. you're best is to follow a tutorial on a save system in unity . . .

[rocky canyon]

give the cards each a value, 0,1,2,3 that way its simple.. use playerprefs (look up tutorial on youtube), where they save a health value or something you would save the value of the card you want to save.. (the one you want to load back into).. then you do that, in a start method of a script or something load in the card (whichever one is represented by that value..

[unborn wasp]

do u have time to help me with that?

So about a week ago I was told to go through all of the c# stuff here: https://www.w3schools.com/cs/cs_getstarted.php and I believe I understand most of it, but now im starting to see that I dont understand how C# interacts with unity, does anyone have a similar 'tutorial' type site for those interactions?

thank you so much

[summer stump]

Keep in mind that Unity is just an API built for C#. So it just gives you methods to call, and classes to inherit from, callbacks to listen to, libraries/packages to use, and whatnot

[buoyant prawn]

that's fair, I jsut basically went back to my project armed with new knowladge and i cannot figure out how to referance game objects and their components within the script, so i felt there was more learning to be done

[summer stump]

Always more haha. But yeah, Unity does things a little different than a pure c# environment like a console app

[paper rover]

Hey! I'm a bit new to coroutines, and I'm trying to play a recording of joystick positions at certain times, but it does not correctly line up with the Updates of the game. Maybe it is because of the yield waitforseconds? How can I fix this?

[gaunt ice]

yield return null

it will wait for one frame

btw there is no way to duplicate the delta time between each frame (you can approach it though)

[lofty gazelle]

I spawn a prefab for an equipment system in UI that has a progress bar, once the equipment is "activated"(its a button) the equipment has different values one being a float for time. The progress bar will fill up in that secific amount of time in seconds.

Im using coroutines for the progress bar, since i instatiate sometimes multiple equipment at once, its a dictionary of coroutines so they each have their own progress bars running independant.

My question is, how would i go about saving the state of the progress bar? If the player leaves the game when a progress bar is 50% filled, when the game loads i want the coroutine to continue firing at 50% and go on.

Ive been stumped on this for a day now.

[prisma silo]

im playing an audio clip through an audio source but the audio quality sounds horrible its loud and it sounds like its playing multiple times at the same time

[timber tide]

what do you mean if the player leaves a game? Does that mean different sessions on a built version?

[lofty gazelle]

i have a save and load system, when the Application is closed it will save the game. Im currently just saving and loading basic variables.

Im making a mobile game, its all UI

[timber tide]

Alright, so the idea is you need to make another coroutine, but this new coroutine should have the last updated variables before you serialize the data for that session.

and by new coroutine I mean use what you have there but with the variables from where you left off (elapseTime should be sent in)

[lofty gazelle]

i will give it a shot! Thank you

[cosmic dagger]

you need to save the info.equipmentProgressBar.fillAmount and load it back. then elapsedTime will be fillTime * info.equipmentProgressBar.fillAmount. also, in UpdateProgressBarOverTime, there is no need for the parameter fillTime; in the UseEquipment method, collectionTime is a local variable stored using the EquipmentData instance. that instance, data, is passed as an argument to UpdateProgressBarOverTime . . .

[edgy fox]

how does 0, hit.transform.rotation.y,0 not meet the required parameter of float, float, float

[timber tide]

eye your brackets parentheses a bit more

when i try to use text it doesnt show up i ngame view

does anyone know why?

[edgy fox]

classic move

[nimble scaffold]

Is there any serious problem if I use Sublime text insted of vs code

[slender nymph]

don't forget that transform.rotation is not in degrees, if you want the Y rotation as degrees use transform.eulerAngles.y instead

[edgy fox]

just found that as everything is rotated 1ish degrees

[slender nymph]

if you do not have a configured IDE you cannot get help here

[nimble scaffold]

I don't need help "there"

[slender nymph]

well if you plan to never get help with any errors here, then feel free to use any IDE you want, including unconfigured ones

a smart move would be to use a supported IDE that is configured to use with unity so that you get proper syntax highlighting, autocomplete, errors underlined, etc.

[lofty gazelle]

Nice catch! You are right! Thank you for the help I’ll try this out

[hasty pine]

dude how am i supposed to reactivate my license?

it asks for a serial number

idfk

wow nvm it MAGICALLY started working

wow

[slender nymph]

usually license issues just require a restart or to return it and get a new one which only takes a few clicks. but also it's not a code issue so #💻┃unity-talk for that in the future

[edgy fox]

whenever I import a model it comes with rotation how do I pre-emptively remove this rotation?

so whenever I instantiate a new one from /imported assets/ it comes not rotated

its greyed out

[timber tide]

blender

there may be some options in the import settings, but otherwise you can always parent it

[edgy fox]

how do I change rotation to 0 through blender?

I tried rotating it in blender and reimporting it but then it was just rotated 90 degrees and still said it was rotated -89.98

[timber tide]

blender has a different system of axis so it's something to look up when you export your model over

[low edge]

whats wrong with my code? its supposed to make the player in my game move around, but its not working. its also supposed to rotate the camera attached to the player but it can only rotate up and down

it says no errors

come on

anybody???

[gaunt ice]

have you tried log the value from input manager first?

[low edge]

wdym

[queen adder]

Hey guys. Not sure if i can ask this here.
I need some help. Im using unity and c#. In my project i have daily missions that are supposed to reset at midnight everyday.
I made a timer that counts down 24 hours and it will then reset my missions. But my issue is if a player logs in for the first time at say 1pm then their 24 hours timer stars from 1pm. Which means their missions will reset everyday at 1pm which i dont want.

Im not very clued up with the date time stuff. I tried googling but cant find a straight answer.
So if anyone knows of a tutorial or document i can read to try help me figure this out.

Of if anyone know what i should write in my code to make these missions reset at midnight for all players then i would greatly appreciate it.
Thanks all.

[timber tide]

would be this based on local time or a server time

if local then you can probably just grab system time

[gaunt ice]

Debug.Log(value you want to see);

[swift sedge]

you can just check if system time is at 00:00

and then reset if so

[low edge]

where do i put that

[verbal dome]

Is this ChatGPT

[low edge]

no

is my code that bad that u must relate it with chatgpt

[verbal dome]

Why do your Update and Start functions have summaries

[low edge]

(jk)

[low edge]

i made them

[timber tide]

I dont even comment my code that well

[low edge]

i said jk

[verbal dome]

Sure

[swift sedge]

nvm

[low edge]

i did it so ppl reading the code can understand what to do

i mean

[gaunt ice]

put log in the place that you just fetch the values

[low edge]

what the code does

got it

[gaunt ice]

int x=X();
Debug.log(x);

[queen adder]

Like i said im not too good with this time stuff haha.
Im using system time.
How would i code that line to see if system time is at 00:00?

Also will the player have to be on at that time for it to reset? Or will it auto reset at that time even if the player is offline.

[gaunt ice]

you know how to use it, you have already used it in your start

[low edge]

ye i got it now

ill try

[timber tide]

serialize the previous time they quit the game then compare it to when they start a new session

[queen adder]

So like a playerpref save of last login time minus current time?

[timber tide]

im more of a json person but sure

[swift sedge]

playerprefs isnt the best option for saving data...

its like not secure at all

[queen adder]

Yeah i know. Im just using it for testing right now.
Everything will be saved to a binary or json later on

Im just not sure how to code the whole time thing to make it reset at midnight.

[low edge]

nothing is being logged

[rapid mountain]

does OnTrigger methods only work when the other collider has either a Rigidbody or a Character Controller?

[swift sedge]

only when the collider is set to trigger

[cosmic dagger]

at least one GameObject involved in the collision must have a Rigidbody or CharacterController, not necessarily the "other" object . . .

[rapid mountain]

ohh i see, because i was confused because my gameobject that had the trigger collider with the script and everything doesnt detect other colliders entering it, unless if it has rb or cc attached to it

[gaunt ice]

you mean

int x=X();
Debug.Log(x);<---this line is not executed?
```the only possibility i know is there is exception being thrown is X()

[low edge]

i managed to make my player move but the camera issue is still there. any help?

[verbal dome]

Which part of the code you showed is rotating thr camera?

[low edge]

nvm i fixed it

it was in a different script i forgot to send a screenshot of that one

but now its fixed

thx for everyone trying to help out

i really appreciate it

[vast vessel]

can scriptable objects have functions that are used at runtime?

[timber tide]

sure

[oblique ginkgo]

Yeah

[low edge]

i fixed, just forgot to save script 😭

[delicate pewter]

Is there a way to calculate time taken ingame accounting for code complexity slowing it down? I know people say Time.deltaTime does account for it but not to my needs at least. For instance as a crude example, my crowd simulation slows down a lot when I do a Debug.Log every update (obviously). The FPS doesnt drop just the movement of the agents for some reason (still smooth just slower). This increases the elapsed time equally which I dont want. I dont want to include any overhead.

[gaunt ice]

i remember someone has told you stopwatch class, or i recall it incorrectly

[honest haven]

Im trying to create states for my animation. I want my player to be idle and be able to attack(maybe a rock or somthing) but also beable to move and attack. I have a few issues. First one is when i attack it stays attacking. how do i know when animation has finished. second is when i move and attack i swap back to idle then attack. this does not work. maybe im doing this all wrong looking for some guidence please https://gdl.space/azagiholuk.cs

[visual hedge]

probably your attack animation is set to loop, you have to disable that, I guess

[river zealot]

if u are using any buttons like wasd to move u can add bool button true

[honest haven]

Sory fixed it i used anystate

with a set trigger and then leads back to idle

[gilded pumice]

Hey all, I'm calling this method and it doesn't seem to break properly (I think the while loop isn't breaking even when it should based on my coding understanding). The method is this:
public void ForwardLight()
{
while (Input.GetKeyDown(KeyCode.W))
{
forwardLight.gameObject.SetActive(true);
if (Input.GetKeyUp(KeyCode.W))
{
break;
}
}
}

and the part where it's being called

void Update()
{
moveX = Input.GetAxis("Horizontal");
moveZ = Input.GetAxis("Vertical");

if (gameOver == false) 
{
    transform.Translate(Vector3.forward * Time.deltaTime * speed * moveZ);
    transform.Translate(Vector3.right * Time.deltaTime * speed * moveX);
    ForwardLight();


}

just really unsure as to why it wouldn't break when the key is released?

[timber tide]

dont use while loops outside of coroutines

update is technically already a loop

[wintry quarry]

It's not breaking because you wrote an infinite loop

The game engine is waiting patiently for your code to finish running before continuing with the rest of the game. But your code will never finish running because it's waiting for some future frame in which the key is released.

That future frame will never come because your code isn't letting the current frame end.

[gilded pumice]

huh, I thought the break statement would execute once the key was lifted

I'll wrap it in a coroutine see if that fixes it

[wintry quarry]

The key will never be lifted according to your code. Input data won't update until the frame changes, and you're not letting the frame end.

I don't understand why you think you need a Coroutine here either

All you need is two if statements, one for KeyDown, one for KeyUp

[dim halo]

guys can I have a question?

[wintry quarry]

You just did!

[halcyon portal]

2 years ago lil bro 🙏

[swift crag]

If you turn on "Apply Transform" when exporting the FBX, the model should come in with no rotation

[buoyant knot]

yes.
That consumed your question for the day

[swift crag]

This causes problems if the model has objects parented to each other, though (like if you have an armature)

I use Apply Transform for basic props

[edgy fox]

I dont but I've been importing via just draggin blend files in and havent had an apply transform option

[swift crag]

Also, I like to switch this to "FBX All". This gets rid of the 100x scale

[novel shoal]

how do i make a coroutine during which something happens, and not one that waits for some time

[swift crag]

When you import a .blend file into a Unity project, Unity asks Blender to export to an FBX file with default settings

So if you want to make any changes to how the export happens, you need to export it yourself

[buoyant knot]

is there a trick to serialize a List<MyInterface>, where all members are serializable? Can I just go for it or no?

[edgy fox]

Ah well was imported quite awhile ago

[swift crag]

I would suggest using this handy add-on

https://github.com/Wildergames/blender-quick-exporter

It lets you export an FBX with saved settings to a pre-set path with one click

[edgy fox]

And all code is set up for rotated thing but I'll make sure to use that later

[swift crag]

I keep all of my .blend files in a Sources folder that's outside of Assets

and I use that addon to export into the Assets folder

[novel shoal]

how do i make a coroutine that affects the gameobject of an amount of time and then stop?

[novel shoal]

instead of waiting some time, it does something for that amount of time

r u there?

[swift crag]

not out of the box, I don't think..

[gaunt ice]

yield return null when make your coroutine waits until next frame

[buoyant knot]

is there an addon or some trick to it?

[swift crag]

Maybe with one of those SerializableInterface packages

I keep mixing them up

[buoyant knot]

those exist? because that would be lovely

[novel shoal]

@swift crag

[swift crag]

one minute. digging around in code

[buoyant knot]

you know how the first time you browse through packages, you have no clue what most of anything is for? good to come back to it and find some gems

[swift crag]

https://openupm.com/packages/net.tnrd.serializableinterface/

I've had a reasonable experience with this

[buoyant knot]

oh tnrd. i used his tags and layers package too

[swift crag]

yeah

i should try that one

[swift crag]

first, think about how to make a coroutine that runs forever

[buoyant knot]

wait so you have or have not tried it?

[swift crag]

I have used the interfaces package. I was talking about the layers/tags one

[buoyant knot]

oh yeah. it’s really good. i can show you a pic of what it looks like

[swift crag]

IEnumerator GoForever() {
  while (true) {
    transform.position += Vector3.up * Time.deltaTime;
    yield return null;
  }
}

This will move the object up at 1 meter per second forever

When you write code, you should always be thinking about the conditions that your code cares about

in this case, there is only one "condition"

while (true)

it's not much of a condition because it's always true

[swift crag]

If you replace that with another condition, you'll get different behavior

[novel shoal]

okk

[swift crag]

while (false)

this would run 0 times

[novel shoal]

so i should use a separate coroutine which waits for that amount of time?

[swift crag]

while (Random.value < 0.5f)
this would run a random number of times

[buoyant knot]

it literally just autogenerates a class with public consts for layers/tags/layer masks

[swift crag]

while (Time.time < 10f)
this would run until the current time is at least 10

that's not quite what you want, but it's pretty close

[swift crag]

You could, but it would be unnecessary.

[novel shoal]

okk

but what does Time.time get?

[swift crag]

https://docs.unity3d.com/ScriptReference/Time-time.html

[buoyant knot]

Time.time gets current ingame time

[swift crag]

It's how long the game has been running for, basically

[buoyant knot]

not real world time

[swift crag]

accounting for time scale, and ignoring big lag spikes

so yeah, it's in-game time

now, consider this

[buoyant knot]

if you set Time.timescale, then Time.time will move proportionally

[swift crag]

IEnumerator RunForTime(float duration) {
  float endTime = Time.time + duration;
  while (Time.time < endTime) {
    // ...
  }
}

what does this do?

[buoyant knot]

so if you set Time.timescale = 0, Time.time will not advance. Time.timescale = 2f makes Time.time advance at double speed

[novel shoal]

it's the time the game has been running + the time you want it to run?

[swift crag]

That's what endTime is, yes.

So what does it mean when you compare Time.time to endTime?

[novel shoal]

so while the time the game has been running is less than how much you want it to run, it will execute that code below

[timber tide]

if you timescale it though it'll no longer be accurate for play session time

there's like a realrealtime variable I think

lel

[swift crag]

right! the while loop will execute until Time.time is larger than endTime

one more thing: what's wrong here?

IEnumerator RunForTime(float duration) {
  float endTime = Time.time + duration;
  while (Time.time < endTime) {
    transform.position += Vector3.up * Time.deltaTime;
  }
}

[novel shoal]

i guess something with Time.deltaTime

[swift crag]

(ignoring the fact that this is now a compile error, whoops)

No, that's okay. We want to move at a constant speed, no matter what the framerate is

(well, it will be okay once we fix the problem, at least!)

[buoyant knot]

Time.time is ingame time. Time.unscaledTime is ingame time if Time.timescale were always 1 (which is useful if you want to time something while paused).
Time.realTimeSinceStartup is the actual number of seconds since game started, which is mostly useless

[novel shoal]

honestly i don't get it

[buoyant knot]

some thing that trips people up a lot with delta time is units.

[novel shoal]

😭

[swift crag]

let's follow what the computer would do

also, I'll make a thread for this

[novel shoal]

okk ty

[swift crag]

coroutine

[vast vessel]

thank you!! I was always wondering why unity scales fbx models to 100!

[timber tide]

I think you can also just change the units inside of blender to prevent that

[buoyant knot]

Remember values have no dimensions, so their units are implicit (eg in your head). Distance has units of meters. Speed in meters per second. Time in seconds etc.
deltaTime has units of seconds.
If you do position += speed, then you are adding meters + meters/second which makes no sense.
if you do position += distance * delta time, then you are adding meters + meter-seconds, which also makes no sense.
But position += distance, and position += speed * deltaTime are both correct

If you keep this in mind, you will never fuck up delta time

[swift crag]

yes -- it's good to do dimensional analysis

[buoyant knot]

dimensional analysis saves lives, and the american school system does a shit job of teaching it

[swift crag]

i remember learning it in chemistry class

[buoyant knot]

i remember my high school chemistry teacher selling condos during class

great realtor

terrible teacher

[deep grove]

can someone make/does somoene have a tutorial for this video:https://www.youtube.com/watch?v=dHzeHh-3bp4&list=LL&index=5
the idea is that i need the pointer to show towards the target at the edge of the screen but for 3D thanks!!

[buoyant knot]

what? isn’t that video a tutorial?

[deep grove]

yhea but for 2d and i tryed it for 3hours to implement it in 3d

[languid spire]

so a tutorial of how to follow a tutorial?

[buoyant knot]

you’re looking for something else I think

you want maybe something more like the compass in skyrim

[deep grove]

i mean the idea of the tutorial

[gaunt ice]

it is quite weird to have a pointer points outside the screen area in 3D
probably a direction on front of foot/body maybe better

[silver dock]

they mean a tutorial of doing the same thing but in 3d instead, since that tutorial is 2d

[buoyant knot]

pointers to the screen border in 3D are garbage

always super confusing

3D games use either a compass or a marker on a minimap

[swift crag]

gimme a Crazy Taxi arrow any day

[deep grove]

i want something like that

[buoyant knot]

no you don’t

[swift crag]

https://www.youtube.com/watch?v=MNHoWdid7ag

[buoyant knot]

don’t enable him

[deep grove]

the underground 2 style arrow if you know what it mean

[deep grove]

thanks

[swift crag]

i only played NFS Underground 1

this is a crazy taxi video, not a tutorial :p

If you want an arrow that points towards the goal...

[deep grove]

that is what i want

[swift crag]

transform.LookAt(goal);

that's about it, haha

[silver dock]

Lmfao

[deep grove]

said it and clicked it after lol

[buoyant knot]

skyrim compass is so much better imo

[swift crag]

you might do something like goal.y = transform.position.y so that the arrow only points horizontally

[deep grove]

ok then what should i do if you say it's a bad idea , but i want to implement it in this view

[buoyant knot]

can the camera change angle

[deep grove]

nope

[buoyant knot]

then pointer at the edge of the screen would work

because this isn’t like full 3d

[deep grove]

ok then you are with me here , how to do that

[buoyant knot]

define the point to look at. define the visible camera area. calculate position and angle of pointer. put pointer there

you need to define the world space bounds of what your camera can see anyway for lots of things in your game

[gaunt ice]

you can get the bound by viewport to world point then to screen ray
not sure if there is better way

[buoyant knot]

might as well do it now

[swift crag]

I'm pretty sure this would be identical to making a cursor in a 2D game

[buoyant knot]

it’s just awkward because 2.5D at angle. He’ll need to define a plane of the level or something

[dim halo]

hello guys, I'd really appreciate if someone would help me with this one

[swift crag]

yeah, Plane.Raycast would make it easy to test where in the world a screen-space point corresponds to

[dim halo]

im a newbie

[buoyant knot]

but maybe viewport to world conversion will make it easy

[dim halo]

[swift crag]

you should be using the version of visual studio that is recommended to you by Unity

[dim halo]

I see

however

[swift crag]

follow the instructions instead of..not following them

[dim halo]

but do you know the reason why it doesnt show me a list of options

like it is the latest version

[swift crag]

because your IDE is not set up correctly

[swift crag]

Does "Visual Studio" not appear in the list of external script editors?

[dim halo]

it does

visual studio 2019

then double click on a script asset to reopen it

[dim halo]

wow

it actually worked

thx man

I appreciate your help

im a newbie i know its frustriating to deal with us

[swift crag]

it's good.

I s hould've guessed you had a problem with the script editor setting given that you were asking about using an unlisted version

[dim halo]

I see

[neat bay]

does anybody know why my animation speed isn't changing even though "Flapping" prints true?

[swift crag]

Your "adjust speed if" function always sets the speed

if the bool is false, the speed is set to 1

don't you want to only update the speed if the condition is true?

context please

VSCode? Unity? Unity Hub?

[neat bay]

ohhh I see its cause these are conflicting right?

[swift crag]

did you try to create a project somewhere weird, like program files

[swift crag]

Yes, because adjustSpeedIf is defined incorrectly

It should not set the speed to 1 if its condition is false

[bright kindle]

Hello! Does anyone know how to make a player die (apply animation too) and respawn when falling for a certain amount of time? For a 2D platformer. Thanks 🙂

[neat bay]

ohh ok nvm thank you

[swift crag]

you would want to add Time.deltaTime to a timer every frame that you aren't grounded

and when the timer gets too large, you triggger the death animation/respawn/etc.

the timer would be set to 0 every frame you're on the ground

(by "timer", I mean a float variable)

[bright kindle]

I understand the point but I don't really know how to do it

[wintry quarry]

What part are you confused about?

[bright kindle]

where do I add Time.deltaTime for every frame that I'm not grounded exactly?

[swift crag]

You'll want to look at the !logs

Hey does anyone have a camera controller script that they are willing to share? Something like Kenshi or Mount&Blade where you move cam with WASD and can zoom in and out

[swift crag]

you want info-log, I believe

kinda sounds like you don't have an editor installed

if you do, i'd reinstall it, then restart your computer

or maybe do those two things in the opposite order

[deep quarry]

why does my Transform layout look like this?

[swift crag]

you have debug mode on

click the triple dots in the top right corner of the inspector and switch to Normal

[deep quarry]

Oh...
Thanks!

silly me

[swift crag]

Debug mode turns off custom editors and shows some extra properties

it's useful for when you want to do Evil Things, like switching which script asset a component uses

(sometimes I do that manually in text editor)

[green island]

i want to add an interface component to the player through code based on which character is equipped the character stats and model are in a scriptible object but how do i do it for the interface

[deep quarry]

Quick question,
Functions must start with an uppercase, right?

[short hazel]

Uppercase first letter of each word yes, known as "PascalCase"

[deep quarry]

Super, thanks 👍

[gilded pumice]

hardModeGameManager = GameObject.Find("Game Manager Hard Mode").GetComponent<HardModeGameManager>();

is this or is this not the correct way to reference another script? In Start(), everything spelled correctly. NRE very very annoying.

[languid spire]

yes, it is correct, syntactically, that does not mean it actually works as I've already told you
if the result is null then the game object named Game Manager Hard Mode does not contain a component of type HardModeGameManager

[gilded pumice]

initialized as private HardModeGameManager hardModeGameManager;

[short hazel]

The easiest and foolproof way of referencing is still making that variable serialized, and drag-dropping the object in the Inspector

Or have another script inject it for you if the object that tries to find it is a prefab spawned later on

[gilded pumice]

It's the literal name of the script attached to the game object. I'll try reattaching I guess

[languid spire]

btw if this line is generating a NRe then the game object Game Manager Hard Mode does not exist

[languid spire]

screenshot the inspector of Game Manager Hard Mode

[gilded pumice]

does it matter if the object is disabled in the hierarchy?

[languid spire]

yes

find wont work on disabled objects by default

[buoyant knot]

is it easy to make an assembly so I can use the internal keyword?

[deep quarry]

I have a function named IsGrounded(), when I call it, it returns true or false.

Is it possible to call this function in a if-statement?
I tried this but it didn't work:

        if (IsGrounded())
        {
            // code
        }

[gilded pumice]

it isn't an issue of disabling it though, I watched it enable on the inspector when I launched the game

[languid spire]

this is why Unity wrote documentation which you should be reading

[gilded pumice]

it isn't because its disabled, I have the same functionality with another game object that has almost the same code and it has no issues being used the same way

[short hazel]

If you can, just drag-drop this object onto your other script to directly reference the HardModeGameManager. Find is not needed here, and almost never is

[languid spire]

bet?

[gilded pumice]

I'll give it a whirl

[short hazel]

Yes that works, as long as the method returns bool instead of void, and that there is a return statement in it for each accessible code path (eg. in an if statement, you would need to return in both the if and else parts)

[gilded pumice]

you are correct but I don't understand why the same script with a slightly different name is working when used this way (disabled at start and enabled when the proper difficulty is selected)

[languid spire]

script exeuction order

[deep quarry]

Thank you very much! :)

[gilded pumice]

yeah I figured it out, I had an object with the controller script enabled at start when it's supposed to be disabled. That seemed to do the trick. Thank you!

[deep quarry]

In the function, I check if the player is touching the ground using a Raycast;
Physics.Raycast(transform.position, Vector2.down, groundedCheckDistance);

Can I use return Physics.Raycast(...) to return true/false?

[gilded pumice]

now they both activate at the same time when condition is correct

[short hazel]

Yes! As Raycast also returns bool you can directly pass it to return

[deep quarry]

Hmm, I get this error when I tried it:
Since 'PlayerController.IsGrounded()' returns void, a return keyword must not be followed by an object expression

[short hazel]

You need to make the method return bool, not void

[languid spire]

so change void to bool

[short hazel]

private bool IsGrounded() { ... }

[languid spire]

that is the return type of the method

[deep quarry]

Ah, now it works!
Thank you once again :) 🙏

Hello Guys , I am facing a problem in developing my runner game for mobile, and this problem is that I want to make a generator for infinite levels that do not end, like runner games, so that you know more about the thing I mean. I mean, I do not want to make infinite tiles. I just want to make a generator that creates stages. Whenever you complete a stage, he gives you another stage, but with different things, meaning the obstacle will be in a different place, and the money is in a different place, and so on, and I want automatically. I mean, whenever you complete a stage, he gives you another different stage, and changes the number of the stage or the number of the stage. For example, when I finish one stage, they are given a stage. Randomly, he writes number two and notes: I never want the stages to be the same.

[short hazel]

It may be referring to another one, do you have the using RPG.Movement at the top so it locates the right class?

[tulip stag]

yes

[ivory bobcat]

Where's your move to function that accepts a first argument of the type Mover?

The move to function shown takes a vector 3.

[tulip stag]

It's a MoveTo function that accepts an argument of the type Vector3. The error message is in my PlayerController script on a line that says GetComponent<Mover>().MoveTo(hit.point);

and hit.point is a Vector3

[short hazel]

Hover over the Mover in the code that produces the error and make sure the tooltip shows it's from the right namespace.
Or you can just Ctrl+Click that Mover to go to its definition

[ivory bobcat]

Error said you tried to pass it a mover object

Show us where you're calling this function

Guys I Have a Problem

[cosmic dagger]

Don't we all . . .

[tulip stag]

What you're looking for is called procedural generation

[ivory bobcat]

Should be line 49 of the player controller script

[tulip stag]

It's not easy to explain quick in a discord message but look up "unity procedural generation" and see if that helps as a jump off point

[tulip stag]

It's this. This is line 49

Yes, exactly how I will do it

Clear the error and try again. The error suggests that you've passed something other than a vector 3.

[quick edge]

Yo! Quick question. I've done my player movement with a CharacterController. Now I want to do a health system (hp, damage, etc...). But I saw that the CharacterController only get collision while moving, this will cause big issues (I think). Is it better for me to switch to a rigidbody ?

[tulip stag]

ok

[short hazel]

Ctrl+Click now

[tulip stag]

Wait how do I clear an error in visual studio

[gaunt ice]

try this

GetComponent<RPG.Movement.Mover>().MoveTo(hit.point);
```force the compiler look for the class under namespace

[short hazel]

The error is legit

[tulip stag]

dear god !

[queen adder]

Character controllers dont have anything to do with health systems furthermore a rigidbody doesnt have anything to do with a health system either.

[tulip stag]

it sent me to a whole different script ... oh fuck 😭

I think I messed up my project big time with Github

[queen adder]

You would have to make a custom class for any health system , damage system, etc

[quick edge]

But I need collisions to know if my player got hit. So it has something to do with CharacterController and Rigidbody ?

[tulip stag]

I tried returning to an earlier version and now it's all messed up I guess the mover script got duplicated

😵‍💫

[queen adder]

You can detect collisions with a character controller? And with a collider + Rigidbody

It doesnt matter which one you choose

They both have colliders

[quick edge]

Yes. But the problem is that I saw that the CharacterController only recognise collision when Moving. But I could take damage while not moving

Maybe that is false, but that's what I saw therefore my question

[queen adder]

The documentation says that yes^^^

[quick edge]

Nice

[queen adder]

But throughout my experience it seems to always detect collisions
