it still casts it back to an int

the performance gain/loss is negligible tbh

[woeful leaf]

probably yeah

I don't use either now though because I realised I just needed to use - lol

I was overcomplicating it

[thin aurora]

I understand the concern about performance - but yeah, the difference you will get between this, and whatever you could come up with to avoid an extra cast, is basically none.

[mental rover]

division by 2 is extremely quick - same as int >> 1

[whole yew]

this is a little bit off topic but where can I find good artwork for the background of my game?

kinda just looking for anything

multiplying by 0.5 could probably be even slower lol

since a divison by 2 is just 1 right binary shift and tits super fast

if you divinding by like 3.14159265 then division becomes slower, but dividing anything by a power of 2 is super fast

you doing that just makes it slower and makes the code look bad

[woeful leaf]

True

I changed it afterwards back to division

[woeful leaf]

Though after that I changed it to this because I realised I didn't need / heh

How would I make my A* enemy jump over gaps?

Or is there a way I can use Unity's NavMesh in 2D?

[woeful leaf]

If it's a certain weight, then jump?

[woeful leaf]

Afaik, no

[hidden kindle]

But right now it doesn't detect gaps

I'm trying to figure out a method for it to detect gaps, but the ones I come up with are a hit or miss

[woeful leaf]

Well I think A* uses weight, so maybe you can predefine a certain weight or smth, or have it so that when it collides with a certain tile it'll run a jump animation

The latter is probably the easiest

[pulsar elm]

Yo, any way to check for objects being rendered by a specific camera?

[woeful leaf]

Probably,

[pulsar elm]

I mostly check unity docs

and I quite did but I also added in "without raycasts" so I only got results about raycasts

[main token]

https://answers.unity.com/questions/8003/how-can-i-know-if-a-gameobject-is-seen-by-a-partic.html

[hidden kindle]

Well, my issue is that I don't want to have to predefine every single gap

But for now, I'll look into the weight thing

[neat lagoon]

this is fairly complicated, you would need to have a cost for jumping over gaps and extend the neighbor search functionality to check the opposing side of the gap from where the current node is during pathfinding iteration

[woeful leaf]

It depends how optimally and realistic you want to have it

[neat lagoon]

if the gap can be more than 1 tile wide, and you need to be able to jump to any tile across the gap (not necessarily just cardinal directions), then good luck lol

[woeful leaf]

Because I assumed that the character can jump any gap, but that's probably not what you want

Pathing isn't that easy

https://dontasktoask.com/

#🔎┃find-a-channel

[neat lagoon]

you might be able to add a new type of node called an "edge" that borders gaps, and when you encounter an "edge" you have some custom pathfinding logic that adds nodes to the open / closed lists based on whatever your conditions are. Like, it could add nodes to the open list if they are within 2 tiles of the origin edge, etc

[hidden kindle]

Would it be easier to make it stop if its going to fall to its death?

[neat lagoon]

what do you mean?

shouldn't that happen automatically since it would, by default, path around gaps?

[hidden kindle]

No, it currently will just continue to follow the player and fall to its death

[neat lagoon]

this makes it seem like you have an A* enemy

[hidden kindle]

I do

[neat lagoon]

so gaps are considered walkable right now?

is this your own A* code?

[hidden kindle]

Technically, yes

[hidden kindle]

It's a heavily modified version of someone else's own A* script

I used it because when I used the AILerp script, my enemy would just float to the player

But I want it to be a grounded enemy

[neat lagoon]

well then, I will say that it would be very difficult to make enemies jump over gaps + include that in the pathfinding if it's not a completely custom pathfinding solution

I think the easiest way would be to fake it, like Wumpie said

you should be able to automatically tag "edges" around gaps with something

and if you encounter those edges, you step through the path via nodes and find the first non-gap node in the remaining path

then you play a jump animation from the start edge to the end edge, on the other side of the gap

you would leave gaps as walkable for this to work

but this also means you don't have much control over the length of gaps that can be jumped over, etc

they would be able to jump over a gap of any length

Hello
i have player which moves Top Left down and right (2D Topdown withought diagonal).
So the Problem is that i have also a Tilemap and i want the Player to kind of Snaps on Middle X and Y of the Tiles in the TileMap.
My code:
private void updateMovement()
{
horizontal = Input.GetAxis("Horizontal");
vertical = Input.GetAxis("Vertical");

    if (Mathf.Abs(horizontal) > Mathf.Abs(vertical))
    {
        vertical = 0f;
    }
    else
    {
        horizontal = 0f;
    }
    animator.SetFloat("hori", horizontal);
    animator.SetFloat("vert", vertical);
    Vector2 direction = new Vector2(horizontal, vertical);
    transform.position += (Vector3)(direction * maxSpeed * Time.deltaTime);
    //updateHookPos();
}

lets Say we have a Tile 32 x 32 and i move the player to the left then he has kind of snap softly to the middle Of Y-Axe
Any Idea?

Kind of like this:

Xd

[hidden kindle]

Do you think I could detect the edge by getting the current object the enemy is colliding with and setting the edges to the left and right bounds of the collider?

And then maybe I could have a raycast coming out from the ground to see if another ground is within a certain distance

[whole yew]

yeah u can do that

[balmy radish]

outch sry

[whole yew]

you can just check the position of the player and set it to the closest value with is a multiple of 32, if that's what you want

[balmy radish]

rivate void updateMovement()
    {
        horizontal = Input.GetAxis("Horizontal");
        vertical = Input.GetAxis("Vertical");
        
        if (Mathf.Abs(horizontal) > Mathf.Abs(vertical))
        {
            vertical = 0f;
        }

        transform.position += (Vector3)(direction * maxSpeed * Time.deltaTime);
        //updateHookPos();
    }

[balmy radish]

could u give me a small example? like under vertical do i have to do that snap?

[woeful leaf]

!cs

[tawny elk]

You can format your multiline code block with C# highlighting! Just add cs to the start of it. Highlighting example below!

class Fluffs : FluffyCat
{
    public void PetCat ()
    {
        Debug.Log ("Petting Cat.")
    }
}

[whole yew]

you want it to snap only on vertical?

[balmy radish]

no and Horizontal depends on the mOvement like when u go to left and right it snap vertically and top and down snaps horizonatly

[whole yew]

int rem = val % 32;
int result = val - rem;
if (rem >= 16)
    result += 32;

this should work

change result instead to your x or y position

[balmy radish]

wait can u modify the code with that? ^^

[whole yew]

this will snap the value to the closest 32

wait

[balmy radish]

ok thx ^^ iw8

[whole yew]

do you want it always snapped on the grid

or what

i dont 100% understand what you want to fully do

[balmy radish]

like softly snapping while moving? is it possiable

like with time.delta time while moving u k

^^

[whole yew]

after you stop moving?

[balmy radish]

no while moving

wait

[whole yew]

hmm

so you dont want it to hard snap, you want it to slowly shift to the nearest grid and not instantly

[balmy radish]

example:
u r not snapping and u r on the 10pixel so while moving it incress to 16 because u k is the middle

exactly ^^

[whole yew]

can u answer my question

[balmy radish]

which one ^^

[whole yew]

this

[balmy radish]

yes ^^

[whole yew]

both x and y?

[balmy radish]

depends on the movement u go right or left then its snaps on Y and top or down it snaps to X

[whole yew]

you said y 2 times

k

i understand

[balmy radish]

sry Xd the problem when u use a German Layout Xd

[lofty barn]

How do I simulate user input in unity?

[whole yew]

    float NextSnapPos(float val)
    {
        int rem = val % 32;
        int desiredVal = val - rem;
        if (rem >= 16)
            desiredVal += 32;
        return Mathf.Lerp(val, desiredVal, lerpSpeed * Time.deltaTime);
    }

I made u a little function

if you give it a float of your position, it will return a next position you should be for that axis

        transform.position += (Vector3)(direction * maxSpeed * Time.deltaTime);
        if (verticalMove)
        {
            // Snap horizontally
            transform.position += new Vector3(NextSnapPos(transform.position.x), 0);
        }
        else if (horizontalMove)
        {
            // Snap vertically
            transform.position += new Vector3(0, NextSnapPos(transform.position.y));
        }

@balmy radish and then something like this maybe

I havn't tested it but you can play around and you need to create the variables for horizontalMove and verticalMove (they are bools) and if you move horizontally you need to set horizontal move true for example

[balmy radish]

wait lemme try it ^^

[whole yew]

and also set a lerpSpeed, if it works, then good, but I didnt make it for that purpose, this should just be an idea how you could solve a problem like this

[balmy radish]

yes thx verymuch it is not working rightnow but i got the idea and iwill change it like that ^^

thx verymuch again ^^

[whole yew]

do you understand the logic though?

[balmy radish]

Yes iam just trying to understand why the player if flying with 15555000000 speed Xd

[whole yew]

LOL

[whole yew]

make lerp speed small then

[balmy radish]

smaller than 0.005`=? XD

[whole yew]

wait

[balmy radish]

XD

[whole yew]

you want 32 pixels right?

[balmy radish]

i said the Sprit is 32

[whole yew]

you want to snap how many units

[balmy radish]

1 only which is the play

i think it has to be val % 1

[whole yew]

ohhh wait then

[balmy radish]

wait can i write to u on private?

Xd

[whole yew]

sure

[muted grove]

Does IL2CPP produce faster code than Mono? Should you use IL2CPP everytime when producing a release build?

[polar marten]

in my experience on desktop platforms, il2cpp produces faster code. on hdrp projects, which have greater cpu needs than urp, i've seen frametime improvements of about 5%

[muted grove]

so il2cpps never slower?

are there any downsides to using il2cpp beside longer compile times

[polar marten]

if it turns out to be slower, usually there is some other bug

[polar marten]

if you author a moddable game, it is much easier to do it targeting mono than il2cpp

[muted grove]

i looked up il2cpp and it looks like unity games compiled with it are very easy to mod with decompilation tools, should i care about that?

[muted grove]

thanks man

[glossy barn]

Can someone help me understand how machine ends up as null? I copy and pasted the file path of my prefab so I'm incredibly frustrated.

[lucid valley]

the Prefab folder needs to be in a Resources folder in order to use Resources.Load()

https://docs.unity3d.com/ScriptReference/Resources.Load.html

[polar marten]

you shouldn't use Resources.Load. simply drag and drop it directly into the slot on your behavior. also, there are spaces in your path. you are on the start of a long journey!

[lucid valley]

^ yeah sorry i didnt actually look fully at your code, i agree with doctorpangloss. Referencing a prefab in the inspector is a lot better than using Resources.Load

you've already made it a [SerializedField] too

[glossy barn]

What should I do if I am going to be changing the prfab a lot though?

[lucid valley]

wdym changing

[glossy barn]

I change it based on player input then instantiate a new Game Object and delete the old one

its a building system

Should I just have like ten GameObject variables and assign them in the inspector?

[lucid valley]

how is the player choosing the input?

[leaden ice]

no you should have one array variable and assign it in the inspector

[glossy barn]

That shouldn't affect it but they use the number keys

[glossy barn]

oh thats a fair point lol

[lucid valley]

number key to array index then?

[glossy barn]

Yeah that's what ill do that's a good idea

Just out of curiosity, how would you do it the "hard way"?

Like if I wanted to grab a prefab with code instead of using the inspector?

[lucid valley]

i probably would never use Resources.Load, and just have some sort of storage system of prefabs in a singleton Scriptable object

but with what you were doing originally you could use Resources.LoadAll from a folder and then make the array but you'd need to have a script on those prefabs to determine the order so your number keys don't change if you add a new prefab

[glossy barn]

Cool

thanks for your help!

[polar marten]

the spaces in your prefab path mean you really, really should not be using Resources.Load

so it's not super clear to me why you want to do things this way

[glossy barn]

The spaces are straight from copying it I don't know why they are there and now worries I figured out a solution

[neat lagoon]

I would personally use addressables if I wanted to grab things without the inspector

[polar marten]

well you should maybe start with #💻┃code-beginner and some tutorials, i like ray wenderlich's because they're nicely written

[glossy barn]

thank you for telling me that 🙂

[warm yarrow]

Hey everyone,
Recently I uploaded my android game to Google Play Store. I have integrated Unity Analytics/DevOps. In the DevOps panel I see that 5 users out of 300 ecountered an error:

Managed Stack Trace:
 
UnityEngine.SceneManagement.SceneManager.UnloadSceneAsyncInternal (UnityEngine.SceneManagement.Scene scene, UnityEngine.SceneManagement.UnloadSceneOptions options) (at <00000000000000000000000000000000>:0)
SceneLoader+<LoadCoroutine>d__10.MoveNext () (at <00000000000000000000000000000000>:0)
UnityEngine.SetupCoroutine.InvokeMoveNext (System.Collections.IEnumerator enumerator, System.IntPtr returnValueAddress) (at <00000000000000000000000000000000>:0)```

I'm unable to reproduce this manually on any of the devices that I own. Here's the code that I use for loading/unloading scenes:

```private IEnumerator LoadCoroutine(string sceneName)
{
    _loading = true;
    var scene = SceneManager.GetActiveScene();
   
    // load transition scene
    yield return SceneManager.LoadSceneAsync(LoaderSceneName, LoadSceneMode.Additive);
    SceneManager.SetActiveScene(SceneManager.GetSceneByName(LoaderSceneName));
    yield return null;
   
    // unload original scene
    yield return SceneManager.UnloadSceneAsync(scene);
    yield return null;
   
    // load new scene
    yield return SceneManager.LoadSceneAsync(sceneName, LoadSceneMode.Additive);
    SceneManager.SetActiveScene(SceneManager.GetSceneByName(sceneName));
    yield return null;
   
    // unload transition scene
    yield return SceneManager.UnloadSceneAsync(LoaderSceneName);
 
    _loading = false;

Am I doing something wrong? Why would this occur only on 5 out of 300 devices? I'd appreciate any help.

[polar marten]

the most likely explanation is an application bug. i don't think there is enough information in this error to definitively say

ideally you would not use scenes

[warm yarrow]

why not? aren't scenes one of the most basic structures in unity?

[neat lagoon]

you could, for whatever reason, have an improper (unintended) state generated via your code that could cause this function you sent to error

[polar marten]

i'm not sure if they provide value for you over prefabs. the issue you're experiencing is one of many anecdotes and problems

related to scenes, and the workarounds needed to do basic things like having an object that persists across scenes

anyway it's everyone's prerogative. i give this advice all the time, and i'm always right about it, in the specific context i give it

i don't know if your game needs scenes

you can probably store all the content in one scene

and use prefabs for your levels

you do not call Resources.UnloadUnusedAssets are you? if you're not calling it, you're not saving any resources, which is what you're about to say as to why you need scenes

even though that interacts correctly with destroying game objects for any reason, not just game objects that are destroyed by unloading scenes

[neat lagoon]

a little silly to recommend such an architectural change when the game is already on the google play store

[warm yarrow]

I don't ever call UnloadUnusedAssets

[polar marten]

5 out of 300 users that can be observed

[polar marten]

Am I doing something wrong?
if you can use just 1 scene, and remove all the complex code you have for deawling with transitioning between scenes, and instead use prefabs and simply
SetActive(true) on thigns that should be visible, SetActive(false) on things that should not be visible, which literally replaces 99% of SceneManager use cases
then in a sense you are doing something wrong. there's nothing wrong with your code here

[neat lagoon]

is it possible that you could be starting this coroutine in quick succession? i.e. before the previous one finished?

[polar marten]

Why would this occur only on 5 out of 300 devices?
given how hard it is to figure this error out, there is probably an application bug relating to multiple game objects with dontdestroyonload or similar techniques to persist between scenes, interacting unusually, in a situation that is hard to reproduce / QA

i don't know, it would probably take me about 2 hours to remove scenes

in a codebase i've never seen

2 hours is nothing

drag and dropping all the content of the scenes into prefabs, creating a new Game scene

removing all the weird code

then using SetActive

it's not bad

i don't know anything about the game

but hey, you've probably spent more than 2 hours dealing with this bug

or will

so it's your call

your game

[neat lagoon]

Yeah, it is his, so chill out on the random controversial suggestions

[warm yarrow]

I don't think so, I block all of the input when scenes are changing and user shouldn't be able to invoke another loading but I'll double check, thanks

[polar marten]

do you see what i mean?

look at how much stuff you have to do

blocking input, toggling loading... for what exactly?

DontDestroyOnLoad?

don't you see

you don't need any of this if you just use prefabs to organize instead of scenes

this is obviously organizational

you can organize your stuff into prefabs

[eager yacht]

all of this effort put into a suggestion he doesn't need

[polar marten]

it is basically thes ame experience in editor

[warm yarrow]

how would switching to prefabs omit the need to blocking the input?

[polar marten]

because SetActive(true) or Instantiate will Just Happen

you already do it all the time

you already use prefabs

[warm yarrow]

but Set active/Instantiate blocks main thread when it needs to load something

[neat lagoon]

Just store your entire game levels in prefabs and freeze your application while you enable / disable them 🤓

[polar marten]

your application will freeze loading scenes too

"async" doesn't mean no freezing

and besides, if you have everything instantiated - i always pre-pool, put a prefab reference directly into the scene, etc - there will be less freezing compared to loading a scene

@warm yarrow anyway you won't fix this problem, trust me

it's extremely obscure

[neat lagoon]

Hmm, well I would consider seeing a moving load screen with an animated load bar to not be "frozen", but I guess we all see things differently

[polar marten]

1.6% error rate... you are going to have to play your game for hours upon hours to reproduce this

[warm yarrow]

@polar marten I appreciate your advice but you are suggesting a solution that interferes with the way Unity is designed

[polar marten]

i am suggesting to use prefabs

which is another way unity is designed

i'm not suggesting any interference

i'm suggesting a solution that interferes with how you like to organize and think, which is, "i have a lobby scene" "i have a game scene"

but unity doesn't care

and i'm suggesting you just have a lobby prefab

[warm yarrow]

how would I bake lightning in the prefab?

[polar marten]

i think there are a ton of google results for this

[warm yarrow]

there might be, but you said you could convert any Scenes system into prefabs system

[polar marten]

that's correct

i would probably just drop the prefabs in and bake them into the scene

[steep herald]

Yeah, you can bake lighting into prefabs

[polar marten]

once

and then move on with life

because that would take like 5 minutes

then move them out

[warm yarrow]

oh, I didin't know that

[steep herald]

love your optimism for baking times

[polar marten]

well, i would bake my assets in a graphics application

[steep herald]

Hah yeah then that makes sense

[polar marten]

is sort of the right answer

none of us can do anything about how crappy unity's lighting is

[warm yarrow]

anyway I feel like this conversation is drifting away

[neat lagoon]

Has been for a long time.

[polar marten]

the error message is telling you something that makes literally no sense

which i hope has illuminated for you how utterly brittle and stupid SceneManager is

it is so bafflingly stupid and frustrating that you could wind up in a situation where a super straightforward piece of code causes crashes

you can probably reason about baking, but this

this is a disaster

we can all speculate about random shit

that can happen during the execution of this coroutine

but i'm sure you've already done that

so people who have never seen yoru game's codebase or even what scenes are being loaded aren't going to have extra insights

the underlying problem is that Scenes are bad

just consider it

1.6% that you observe. it's possible that many, many users will eventually see this bug and drop out

[warm yarrow]

okay, I'll keep that in mind, but I'm sure most of the unity developers use scenes

[polar marten]

which is why i find crashes like these so frustrating

[neat lagoon]

I have used scenes with no issues for nearly all my projects, albeit I generate and populate them at runtime. I do still use pre-populated scenes for things like levels and have never encountered issues.

[warm yarrow]

and they find a way to do that without issues

[muted grove]

does unity have a situation where you end up writing everything yourself

[polar marten]

like 1.6% error rate isn't small - people who stop playing stop generating data, so it's possible to observe 1.6% reports for an error that, eventually, 100% of users experience

[eager yacht]

I've never had issues with Scenes

[muted grove]

like a windows C/C++ runtime kinda deal

[polar marten]

they write a lot of code to work around using scenes

[mental rover]

I'm not sure I believe most Unity developers have not run into issues with Scenes

[polar marten]

like DontDestroyOnLoad, "brain" scenes, etc. etc.

most unity developers ship 0 games

and you have, you have a game that's live with a finger pointing right at scenes!

i mean that's what the error message is saying. "this seemingly straightforward and obvious pattern, i'm just going to decide it doesn't work for you, because scenes"

one of the requirements i have for people who use an sdk i develop is that they have only one scene lol

because it's SUCH a common problem

and 100% of the games that use this sdk will be shipped, so there's no point in letting people "organize" or whatever

they can organize using prefabs

[polar marten]

most of the time people are rewriting stuff in a negative return-on-investment sort of way. i see this most commonly with Amplify Shader Editor users

that said, the workflow i'm describing is literally dragging and dropping prefabs into a scene, and then using SetActive wherever you would do scene loading. that's it, that's the whole idea

you get to eliminate a ton of other code by doing things this way, so it is definitely ROI positive

[warm yarrow]

I think that would work for a small game that doesn't need complex memory management

[polar marten]

you can Destroy then call Resources.UnloadUnusedAssets()

the number of lines of code between this method i'm suggesting and scenes would not change, in order to do "memory management"

[warm yarrow]

but I wouldn;t be able to set it active again

because it was destroyed

[polar marten]

then i suppose you'll have to instantiate

all things you've done a million times before

[warm yarrow]

and that would freeze the application unless I used Resources.LoadAsync or asset bundles

[polar marten]

that said, i think you should try to not juggle the memory like this unless you really have to. for mobile devices, you will get higher yield compressing your textures, mesh combining with an asset, atlasing, etc. than futzing about with all of this

[polar marten]

loading a scene asynchronously also freezes the application. surely you have observed this. it's not what async loading does

async doesn't mean not freezing

if you want to throw up a loading thing

you can do it. setactive on a loading UGUI panel

the progress bar will freeze, but it does that anyway, in both scenarios

[hardy wren]

hello is there a way to change FixedTimeStep from script?

[warm yarrow]

hmm you can get animated progress bar with using load async so there's no way it completly freezes the application

[polar marten]

the key difference between what i'm describing and what you're describing with SceneManager is bugs

you know i'm talking about stuff that doesn't cause bugs!

[neat lagoon]

Time.fixedDeltaTime = yourValue;

[eager yacht]

Can you guys move this into a thread in case others have questions?

[polar marten]

if you do not observe "freezing" with async loading, you won't observe "freezing" with setactive on a gameobject in your scene. however, as you know, you DO see freezing with SetActive on a game object in certain circumstances, and that same freezing IS occurring when loading a new scene with that same game object active for the first time. loadasync's superpower is dealing with assets that are on disk and turning them into something that the game engine can use, which i agree is valuable and can reduce freezing

but here's the thing: a user will literally never complain about stuttering during a loading bar on screen - the amount of total time they're waiting will be the same regardless of whether or not you use scenes or prefabs or anything - whereas they will stop playing if your game crashes

@warm yarrow so what i am basically saying is: scenes are useful but they are full of bugs.

they're full of bugs that make people quit

it's your prerogative, it's your game

[warm yarrow]

I appreciate your feedback

i am trying to get the tile coordinates of a tile clicked, using the built in Unity tilemaps, however for some reason i am always getting the same position:

Vector3Int tilemapPos = tilemap.WorldToCell(Camera.main.ScreenToWorldPoint(Input.mousePosition));           Debug.Log(tilemapPos); // always returns (-1, 1, 0)

[tired egret]

how do I reset the model after an animation?

I call

player.animator.Play("DeathAnimation", -1, 0f);

then the body has the effect of laying on the floor, then after 5-6 seconds I want to "respawn" the player but he's stuck in the lying down position

[potent sleet]

how big is the tilemap board

debug the raycast

[potent sleet]

use transition states

[fiery oracle]

something like 10 x 10 to test, nothing crazy

[tired egret]

i might have figfured it out

[potent sleet]

did you figure it out ?

[wintry stone]

does anyone know how to change a value over time while being able to modify It? I have a function that that when called, will lerp a value over to 3 over 1 second. The only problem is if I call this function again say .5 seconds before the other ends the values get messed up. I need to be able to call the function again so if you call it half a second after the first it adds to the other value so it than takes 1.5 seconds to lerp to 6 can anyone help?

[leaden ice]

Just use MoveTowards

float current = 0;
float target = 0;
float speed = 1;

void Update() {
  current = Mathf.MoveTowards(current, target, speed * Time.deltaTime);
}

void SetTarget(float newTarget) {
  target = newTarget;
}```

[wintry stone]

Ok will try this thanks a bunch! I appreciate it

[distant glen]

I've included some code of mine (that doesn't work) but it's just there as a reference.

Let's say I have three scripts. PanelsManager, PanelsParent, and ItemPanel.

PanelsParent serves as a parent to instantiated ItemPanel prefabs.

ItemPanel prefabs have the ItemPanel script, which takes information about Items in the player inventory and displays them in the ItemPanel.

PanelsManager takes care of adding and removing ItemPanels as children to the PanelsParent Transform.

I have no problem instantiating one panel for each Item in the players inventory.

However, what I want to do, is only display one panel per item type. For example, if I have three swords in my inventory, and two shields, two panels will be instantiated, one panel for a sword, and one panel for a shield.

My script isn't working for this. It will display the first item, but after adding a second, no panels will display at all.

Has anyone had a similar problem using the Unity Localization Package? Every time I save I get this error:

A little confused, the documentation says LineRenderer.GetPositions should be given an out keyword parameter but it's returning an error, what's going on?

[polar marten]

does this happen in all yoiur scenes?

it looks like your project is in some jeopardy. do you use source control?

[polar marten]

do what your editor is saying

[polar marten]

also, your editor is configured right?

[somber nacelle]

don't forget to initialize your array

[next crescent]

How so?

[next crescent]

almost forgot, making progress now

[somber nacelle]

also what version of unity are you using? because older versions did not have that as an out parameter, just as a regular parameter

[next crescent]

2021.3

[leaden ice]

See what your IDE says the method signature is

the docs might be out of date or just wrong

According to mine it's just a regular parameter, no out

out wouldn't really be needed for an array parameter anyway, since arrays are reference types. I think the docs are just in error

[next crescent]

Doesn't exist?

[leaden ice]

you're mousing over positions which is your array

mouse over GetPositions

[next crescent]

oh whoops

Ah right

[polar marten]

yes, do what the editor is saying

you are looking at the docs for an older version of unity than you are using

[leaden ice]

Nah the docs are actually just wrong

[polar marten]

really?

[next crescent]

How quirky

Thanks though, appreciate it

[leaden ice]

Yeah. At least for 2022.2 they are.

Docs for 2022.2 say out but Rider says no out.

[somber nacelle]

yep, just checked 2023 and there's no out param but the docs say there is

[leaden ice]

I reported the doc page as incorrect, not that this has ever yielded any results in recent memory 😆

[polar marten]

well if you want to send some reports directly to the trash you can do that right from the comfort of your desktop

[leaden ice]

Funnily enough I'm reading 1984 right now and there's a lot of mention of "memory holes"

It seems like this is a memory hole 😆

[tired egret]

what am i doing wrong? i confirmed the two objects are in layers "Bullet" and "DeadPlayer", yet they are still colliding?

[somber nacelle]

are you looking at the correct physics settings? if you're in 2d make sure you're modifying the matrix in the Physics2D settings

also not a code question

[tired egret]

ok ty let me see

thank you! i think that's it (it wasn't set in 2D)

sorry i didn't know

[silver lichen]

it is a newly created 2D project (URP) and has only the default scene. I'm using git.

[hard sparrow]

No motion is being produced. Anyone know why? The idea is curved movement.

[potent sleet]

debug values

[hexed pecan]

Hmm why are you updating/populating _startPosition inside the loop?

[fiery oracle]

no, i didn't

np, was just wondering if i was missing something obvious

[potent sleet]

maybe it's the Z position

did you try to just set it to 0 since that seems to be your Z

[hard sparrow]

For if the end position moves it will continue towards new position from current position

[hexed pecan]

But what is _startPosition when the coroutine starts?

[fiery oracle]

okay, thank you

[hard sparrow]

transform.position

Hm so all the time values are coming out correctly... Is there something wrong with the AnimationCurve?

[wide dock]

using UnityEngine;

public class MapRules : MonoBehaviour {
    // Set up in inspector on each map if required
    [SerializeField] private bool _canTP;
    [SerializeField] private bool _canAttack;
    ...
    
    private static int _mapRules; // Up to 32 rules (1 << 31)
    public static bool canTP {
        get => (_mapRules & (1 << 0)) == 1;
        private set => _mapRules = value ? _mapRules | (1 << 0) : _mapRules & ~(1 << 0); 
    }
    public static bool canAttack {
        get => (_mapRules & (1 << 1)) == 1;
        private set => _mapRules = value ? _mapRules | (1 << 1) : _mapRules & ~(1 << 1); 
    }
    ...

    private void Awake() {
        UpdateRules();
    }
    private void UpdateRules() {
        canTP = _canTP;
        canAttack = _canAttack;
        ...
    }
}

Yo, I've been thinking of a way to set up different rules on each map of my game and came up with such an idea, but I don't really yet fully understand what properties are in C#
Is my understanding here, as to how should I use them, correct or should I do it in some other way instead?

[glacial halo]

I am having such a weird brain blockage at the moment, and embarrassingly it's something I always seem to have a problem with. lol.

Could someone point me in the right direction on this one please?

I have a ray shooting out from the camera that hits an object, and I'm trying to get the object to move to the player, but for the life of me I can't figure out how.

Here's the code, I know that it's massively messy, but atm I just want to get it to work. lol.

I just can't get animation curves to do anything for me. There are tutorials, but none of them have to do with moving an object along a curved path

Even asked chatgpt, it also doesn't know what's wrong, lel

[lucid valley]

[Flags]

    None = 0,
    CanTP = 1 << 0,

Ah, very true, thanks
I'll do that

But besides that it's ok, right?

[lucid valley]

but yeah properties i think are ok for that

some people might say only have those be getters and use a function to set instead

public static bool CanTP => (_mapRules & MapRules.CanTP) == 1; 

public void SetTpState(bool state)
{
    _mapRules = state ? _mapRules | MapRules.CanTP : _mapRules & ~MapRules.CanTP;
} 

[hexed pecan]

Are you sure you are starting the coroutine with StartCoroutine

The fact that you say "no motion" makes me wonder if it runs at all

[wide dock]

I see

[hard sparrow]

Basically what's happening is the object immediately teleports right to the end point, or very close to the end point. Then doesn't do anything else. And it's being caused by the coroutine because when I comment it out, it just sits at the start position

[hexed pecan]

So are you changing startPosition before the coroutine starts?

[hard sparrow]

Only thing I can think of is the curve.Evaluate is being weird

[hard sparrow]

no. I just meant it stays wherever it was spawned

[hexed pecan]

Can you paste your code here so its easier to refer to

In your current while loop, you are updating the gameObject's position before you have changed _startPosition

Isn't if(_endPosition != transform.position)
supposed to be if(_endPosition != targetTransform.position)?

[hard sparrow]

https://hatebin.com/oasqyzkcsl

[hard sparrow]

K, I have movement now. Yay. The movement is very bizarre and not what I predicted, but still

[wide dock]

with [Flags] can't i just make the properties have only get, make a [SerializeField] private MapFlags mapEnumFlags and set the rules with mapRules = (int)mapEnumFlags ?

[lucid valley]

yeah, if you only need to set in the inspector

[wide dock]

I see

good

thanks

[cedar pivot]

how can i make a freekick system for unity

[hard sparrow]

If you wanted to use an animationCurve to move an object in an arc, wouldn't you do this?
transform.position = new Vector3(_startPosition.x + xCurve.Evaluate(elapsedTime), _startPosition.y + yCurve.Evaluate(elapsedTime), 0);

[potent sleet]

like soccer freekicks?

3D or 2D

myriad of ways to do it

[cedar pivot]

3D soccer freekick,

[cedar pivot]

and thanks i needed this

[hard sparrow]

lol, don't use that. I'm trying to use it and I can't get it to work

[cedar pivot]

oh xd

hmm

[potent sleet]

this wont work well for you because they are set curves

you probably want physics + forces

[cedar pivot]

yeah

[hard sparrow]

Idk, football game using set curves could be pretty fun

[potent sleet]

you can charge up your shot and kick it, idk anything about your setu tho

[cedar pivot]

💀

[cedar pivot]

i dont need a very advanced system, but a ball going towards the target is enough for me for now, the most important part is curve.

[hard sparrow]

Imagine a pause-and-play football game where you have to choose the right curve to kick the ball in, like a strategy game

[potent sleet]

what kinda view like this ?

my picasso skills

but um, like bar to charge shot ?

shoot infront of goal?

[cedar pivot]

nope, wait

[hard sparrow]

Good luck, curves are apparently the hardest thing in unity

[cedar pivot]

this camera position is same with my project

[knotty sun]

it is no harder to implement a curve than a straight line

[hard sparrow]

show me how, lol

[cedar pivot]

can chatgpt do this xd

im gonna try

[potent sleet]

this isn't very difficult

[knotty sun]

google C# bezier curve algorithm

[potent sleet]

break it down to smaller tasks you need to get done @cedar pivot

you have a very open ended question

too many abstact ideas floating , we need to know specifically what mechanic your first working on and need help with

[hard sparrow]

K I'll try to do this instead of trying to use AnimationCurve. But I find it hard to believe something is as easy as a straight line when you have to do stuff involving

[cedar pivot]

so, it makes more sense to improve the system and ask you where I got stuck while developing it.

[tough storm]

random question, how do we feel about the built-in unity character controller component

[potent sleet]

exactly

[knotty sun]

you do not need to understand the underlying math to be able to implement the algorithm

[potent sleet]

is pretty good and can be customized easily

[hard sparrow]

not until something goes wrong and you have no clue how to fix it lol

[hexed pecan]

Bezier curve is just a few lerps

[hard sparrow]

fine, I'll do math witchcraft

[hexed pecan]

But im not sure why this wouldnt work. Check the scale of your curve's keys, and that elapsedTime is a correct value

[tough storm]

yeah, it seems super easy to use

[knotty sun]

Did you even bother to google?
https://stackoverflow.com/questions/13940983/how-to-draw-bezier-curve-by-several-points
this give you all the code you need

[hard sparrow]

Ah, so you need to dynamically change the curve's scale?

[hexed pecan]

No. Just look at the keyframes in the curve. And check that the value is something sensible like 1 (not 0.001)

And the time value of the keyframes too.

[tough storm]

here's an interesting question, if you had to have a collection of default components, almost like a template for a 3D game, what would you use? i'd probably use cinemachine, character controller, and then i guess fill in the gaps with stuff like healthbar/resourcebar scripts that ive made a million times

[hexed pecan]

@hard sparrow
Another resource for beziers, with nice visualizations:

[wide dock]

    [Flags] private enum MapFlags {
        None = 0,
        CanTP = 1 << 0,
        CanAttack = 1 << 1,
        CanOpenBook = 1 << 2,
        CanUsePotions = 1 << 3,
        ResetEffectsOnLoad = 1 << 4
    }
    [SerializeField] private MapFlags _mapFlags;

    private void Awake() {
        _mapRules = (int)_mapFlags;
    }

I am kinda confused..
I set up CanTP, CanAttack and CanOpenBook in the inspector, when debuging _mapRules, it's correctly showing 7 (1+2+4, first three flags) but when debugging all the properties, only canTP shows true while the rest is false.
I must be blind, can someone show me what am I doing wrong here?

oh..

I spotted it, nwm.

shouldn't be ==1 everywhere

!=0

[tough storm]

was about to say that

[lucid valley]

ah i think it might be != 0

though i'm not the best with flags

[tough storm]

also, ive never seen that [Flags] property before

[wide dock]

Yeah, it should be that..

[lucid valley]

and i usually just cheap out and use _mapRules.HasFlag(MapFlags.CanTP); (if you make _mapRules into MapFlags type)

but it is worse performance than doing it manually

[tough storm]

wut, tahts a function?

how much worse tho

[wide dock]

Me neither, learned about it just today, quite handy

[tough storm]

what does it do?

[lucid valley]

https://vintay.medium.com/enum-flags-in-unity-and-c-e8af3fee3fc0

• in inspector

[lucid valley]

though i gave the bit shift example

[tough storm]

absolutely wild, cant believe ive been doing it manually this whole time

[lucid valley]

basically multi bool

[whole yew]

how can I make my volume setting save through scenes?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;

public class SoundManager : MonoBehaviour
{
    public static SoundManager Instance;

    [SerializeField] private AudioSource musicSource, effectsSource;

    private void Awake()
    {
        if (Instance)
        {
            Destroy(gameObject);
            return;
        }
        Instance = this;
        DontDestroyOnLoad(gameObject);
    }

    public void PlaySound(AudioClip clip)
    {
        effectsSource.PlayOneShot(clip);
    }

    public void ChangeMasterVolume(float volume)
    {
        AudioListener.volume = volume;
    }
}

currently, I have a sound manager like this and its in the main menu scene, but when loading into another scene it seems to reset the audio back to 100%

[lucid valley]

try moving the ChangeMasterVolume(0.1f); to above the DontDestroyOnLoad(gameObject);

[whole yew]

no, ignore that part

the function "ChangeMasterVolume"

gets called by another script anyways

that was just a test sorry i forgot to remove that from the code

[tough storm]

you could use the PlayerPrefs system

void SavePrefs(float masterVolume,...){
  PlayerPrefs.SetFloat("masterVolume",masterVolume);
  
  //best practice to prevent dataloss is to store floats as a string, this avoids floating point error
  PlayerPrefs.SetString("masterVolume",string.Parse(masterVolume));
  //believe this saves to disc, not sure if needed or not
  PlayerPrefs.Save();
}```

i would also recommend looking into the unity mixer if you haven't, that could help you create even more options for volume/mixing

[distant glen]

Help needed. For some reason, when I interact with my soil when it's SoilState.Harvestable nothing happens. SoilState.Overgrown functions as intended but I can't even get the Debug.Log to show for SoilState.Harvestable. I've tried removing the switch and replacing it with if statements, I've tried just having the code say if (currentSoilState == SoilState.Harvestable) { Debug.Log("Working") } but I get nothing. I can verify that the soil's state is set to harvestable because the inspector clearly shows it.

[lucid valley]

are you changing it anywhere in code?

[potent sleet]

how do you set the states ?

[distant glen]

Setting them from here.

[potent sleet]

where are u calling UpgradeGrowth

[potent sleet]

did you debug isGrowing ?

[lucid valley]

wait, sorry is "Nothing to cut." being logged?

[deft cairn]

Hello how can I create a 3d tilemap?
I tried creating a lot of square planes using 2 for loops but it kills my CPU and RAM. Is there an optimized way to create it?
I want to make something like this

[potent sleet]

put them in a coroutine

[distant glen]

No

[lucid valley]

how are you calling SickleSoil()? as that doesnt seem to be working if you are not getting any log

[deft cairn]

explain

and thank you for replying

[potent sleet]

do you mean you "lock up" when you generate

or you lag once it's generated

[deft cairn]

it lags in runtime, after being generated

this is my map, it's composed of a lot of squares

every square is a tile

[potent sleet]

eh you'd probably want Dots or chunks then

[distant glen]

To clarify, "Nothing to cut" is logged when the soil is activated on any other state other than Overgrown and Harvestable. If the currentSoilState is SoilState.Overgrown the code functions as intended. The code for SoilState.Harvestable is exclusively not working.

[potent sleet]

it doesn't seem too big tho

[deft cairn]

what are those?

[deft cairn]

it's 100x100

[lucid valley]

well this is wrong
To clarify, "Nothing to cut" is logged when the soil is activated on any other state other than Overgrown and Harvestable.
you are using break; in the switch so "Nothing to cut" should always be logged even on those states.
so you must not be calling SickleSoil correctly, trace it backwards

[potent sleet]

maybe it's just your pc then, check it with the Profiler

[distant glen]

if SickleSoil() is not being called, why does the code for case SoilState.Overgrown execute?

[lucid valley]

unless you are throwing due to an error it should log "Nothing to cut" everytime you call SickleSoil no matter what happens in the switch

[distant glen]

Okay, "nothing to cut." shows for the Overgrowth as well. That was my mistake.

[deft cairn]

ill try

[distant glen]

It's only Harvestable it doesn't show for.

[lucid valley]

well that means that some check is blocking SickleSoil running when it has the Harvestable state

i can't help you much more without seeing the full code

!code, you can paste it to one of those sites if you need further help

[simple mountain]

what do you mean by 3d tilemap?

[distant glen]

Can anyone identify why my code is throwing an error on Line 113?

https://gdl.space/lidiqatabe.cs

This script was functioning as intended, but I moved the script to another GameObject, and since then, it has been throwing a NullReferenceException on Line 113 which seems to indicate that "selectedSeedListPanel" is equal to null.

What I don't understand is why moving it to another GameObject would cause the issue, as everything is still being properly instantiated, and everything else is functioning correctly.

Moving it back to its original GameObject resolves the issue, but I need to move it as it was not an appropriate place to have the script.

[lucid valley]

if (ci is SoilObject soil)
{
    soil.PlantSeed(selectedSeedListPanel.seedContained);       
}

You can do this fyi

[somber nacelle]

is not as

[lucid valley]

oh yeah is not as sorry

[distant glen]

it can't be that it's not reaching the seedContained variable in selectedSeedListPanel, because the instantiated panel contains it, so it must be that selectedSeedListPanel is equal to null. However, when one of the panels is instantiated, the class subscribes to that panel's callback, so that when it's clicked, the selectedSeedListPanel is updated to that panel.

Moving the script shouldn't change that, and the fact that I'm getting the error means that the callback is functioning...

[somber nacelle]

are you certain that the updateSelectedSeedPanelCallback is being invoked with a non-null value passed as a parameter?

[distant glen]

This is the only place it is being invoked.

[somber nacelle]

0 references
so where are you calling that method from?

[distant glen]

When clicking this button.

The script (SeedListDisplay) was originally attached to UI_SeedPrompt and I get no errors when it is attached to this GameObject. The problem is non-existent.

However, I re-attached it to UI Manager instead, as UI_SeedPrompt is not always active.

Since attaching it to UI Manager, this is when the NullReferenceException started appearing.

[somber nacelle]

i'd place some breakpoints and make sure that the methods are being executed in the order you are expecting them to be

[distant glen]

Well, clicking a Frame executes the callback method. I can't see any reason why the seedListPanel shouldn't be updated with the rest of the code. It's not being cleared anywhere else.

[deft cairn]

something like this

[simple mountain]

How are you creating this?

[spark wedge]

I'm interested in implementing sprite generator or something
Not sure what to call it but you can see that each can be connected by a that brown part(root)
I'm interested to know if there's an interesting/fast method to implement it without do it statically

Like a mesh generator or a spline maybe and if it's in the case of spline, would it be easy to implement(Within a short duration of time)?

[next crescent]

The shape the linerenderer I have is rendering is a little off kilter, but all the points are whole numbers. What's going on here?

[next crescent]

This is the exact same idea we had for our jam at first xD

[spark wedge]

I'm trying to make it so when the player kills an enemy, after 3 seconds the enemy will sink into the ground but the ground is interfering with the enemy even though the enemy's collider is disabled. And in the Scene when the in playing, I am able to move the Enemy's position through the ground manually with no problems. Any idea why? https://streamable.com/a950eu

Vector3 targetPos = new Vector3(transform.position.x, transform.position.y - 3, transform.position.z);
transform.position = Vector3.Lerp(new Vector3(transform.position.x, deathPos.y, transform.position.z), targetPos, 0.1f * Time.deltaTime);
if (transform.position == targetPos) Destroy(gameObject);```

[distant glen]

It's so weird. selectedSeedListPanel is successfully assigned a value. It's not changed from anywhere else. When it is called it's null - but only when the script is on my UI Manager class, and not the parent class of the tree that instantiates my panels.

[simple mountain]

maybe remove ridgidbody as well

[distant glen]

Now I can even see in the inspector that it is assigned a value?? Why would Debug.Log() show it as being null when the inspector clearly shows it as an assigned value?

[pearl otter]

It doesn't have a rigidbody

[simple mountain]

I think you got something wrong about the lerp function

[pearl otter]

Which part of it? I followed the documentation

[simple mountain]

if(getsKilled)
{
int steps = 20;
Vector3 pos = transform.position;
Vector3 goal = new Vector3(pos.x,pos.y-3,pos.z);
Vector3 interval = (goal-pos)/steps;
getsKilled =false;

}
if(isdying)
{
    steps--;
    transform.position+=interval;
  if(steps==0)
  {
    isdying =false;
    GameObject.Destroy(gameObject);
  }
}
//Try this I know this can be simplified but having more readable code is worth it when you have an error that you can t find

[pearl otter]

Why aren't you using lerp? 🤔

[simple mountain]

wait this is false as well

I am

[pearl otter]

If you look at the video, it really looks like the enemy is colliding with the ground

[simple mountain]

it does indeed

[simple mountain]

but what seems of about your code is that you don t make a difference between the enemy having died and being dead

[pearl otter]

I already did that, I just didn't send that code

I just sent the relevant code

[simple mountain]

idk I'd be great if you tried mine and if it doesn t work you can still use urs

[pearl otter]

Actually I changed the negative to a positive to see if it will float into the air and it does the same thing so its definitely not an issue with colliders.
I will try your code but I've always used lerp with no issue.

[simple mountain]

the thing I wrote is just like lerp I think

[visual flare]

anyone knows what that does?

[pearl otter]

@simple mountain It works, thanks!

[visual flare]

[stuck forum]

Just experimenting randomly with some things. Would this be a good thing to do? Only thing vs complains about is Cannot initialize type 'float' with a collection initializer because it does not implement 'System.Collections.IEnumerable' (Which sadly I need a dll for it) but then again, is this a valid way of doing it?
Edit: maybe it's not a dll? Potential fixes aint giving any useful fixes though

        float[] deltas =
        {
            new float { firer.x - target.x },
            new float { firer.y - target.y },
            new float { firer.z - target.z }
        };```

firer and target are just vector3 parameters of the method

wait

nvm still dont know

[mossy snow]

float[] deltas = { firer.x - target.x, firer.y - target.y, firer.z - target.z };
but I wouldn't do it like that, why allocate an array?
Vector3 deltas = firer - target;
You can still iterate through deltas if you need to do whatever it is you're doing with deltas

[stuck forum]

only thing i wanted to do is sort which delta had the highest value, so i thought OrderBy would do the trick

hence why i wanted to make an array

[mossy snow]

float maxDelta = Mathf.Max(firer.x - target.x, firer.y - target.y, firer.z - target.z);

you can slap in abs in there if you're looking only at magnitude

[stuck forum]

huh, didn't know Mathf.Max was a thing

TIL

[mossy snow]

technically the optimal solution is two maxes imo, since the 3 parameter version allocates an array which should be avoided in a hot code path which it sounds like this will be

[stuck forum]

ouch... that's not good

[tight ice]

hi, i'm trying to do
float waveHeight = WaveManagerGerstner.instance.GetWaveHeight(transform.position);

but it's mad that i'm feeding it the transform.position. it says: There is no argument given that corresponds to the required parameter '_y' of 'WaveManagerGerstner.GetWaveHeight(float, float, float)'

the getwaveheight function in question is:

` public Vector3 GetWaveHeight(float _x, float _y, float _z)
{
Vector3 gridPoint = new Vector3(0, 0, 0); //vertexData.vertex.xyz;
Vector3 tangent = new Vector3(1, 0, 0);
Vector3 binormal = new Vector3(0, 0, 1);
Vector3 p = new Vector3(_x, _y, _z);
Vector3 currentPosition = GetWaveAddition(p, gridPoint, ref tangent, ref binormal);
Vector3 normal = Vector3.Normalize(Vector3.Cross(binormal, tangent));

    Vector3 displacement = GetWaterDisplacement(_x, _y, _z);

    for (int i = 0; i < 3; i++)
    {
        Vector3 diff = new Vector3(_x - currentPosition.x, 0, _z - currentPosition.z);
        currentPosition = GetWaveAddition(diff, p, ref tangent, ref binormal);
    }

    return currentPosition;
}`

i'm quite confused; why is it not happy with what i am feeding getwaveheight function?

[dusky lake]

var pos = transform.position;
float waveHeight = WaveManagerGerstner.instance.GetWaveHeight(pos.x, pos.y, pos.z);

[dusky lake]

^ it wants the x,y,z properties of the position vector, not full vector

How good is unity's navigation and pathfinding?

[quaint rock]

depends on your usecase

if you have navmesh based navigation for 3d its fine

or as long as you can bake the navmesh and do not need to make large changes to it at runtime

[lime niche]

ahh okay

[quaint rock]

i have used it for some projects, and i have just implemented my own pathfinding system on others. depends on the needs at the time

[lime niche]

ah what are the use cases where you have to implement your own pathfinding sys

JsonUtility isn't super clear about what happens when things go wrong. If it attempts to deserialize data that is corrupted will it throw an exception or just return null? https://docs.unity3d.com/2020.2/Documentation/ScriptReference/JsonUtility.FromJson.html

hey, i have this variable called speed in a base class and in the child im trying to do animator.SetFloat("speed", Mathf.Abs(direction)); but it cant find the float speed

i couldnt find anything on the docs

[quaint rock]

the speed in animator.SetFloat has nothing to do with your base class

its setup in the animator its self in parameters

https://docs.unity3d.com/Manual/class-AnimatorController.html

https://docs.unity3d.com/ScriptReference/Animator.SetFloat.html

[fathom lynx]

ahh, so this is because i havent set up anything in my animationer yet

[quaint rock]

yeah the various animator.SetX methods are for setting paramaters on your animator controller

[fathom lynx]

ahh, so i should rename it to like animation_speed right?

[quaint rock]

the string you give it depends on what you have setup in your animator controllers parameters

the docs give a example of usage

[cinder kindle]

why is it -90?

[rain minnow]

Line 13 has a reference variable that is not assigned a value, that's all . . .

Look for any reference variables on that line and make sure they are assigned a value . . .

[rain minnow]

Why not make/set the rotation to 0. That should be it's default. If the x axis is -90, then that's probably when they're face down . . .

ok

whichever silly man told me to make a capsule collider array you have screwed me over for 2 weeks

for some reason this fucks with networking

are there ways other than manually defining a long list of [SerializeField] CapsuleColliders now

whatever ill do it

[dusk apex]

Depends on the contents of the list. They'd have their default values. Reference types would be that of null.

[dusk apex]

What errors are thrown? What's actually breaking? What do you mean by this?

are there ways other than ... now
Ways to do what?

[deep willow]

hmm okay so its not working because when i do this:

gameManager.spellQueueList.Add(gameObject);

the object is still not being added for some reason

it stays null

[frank pumice]

nvm kind of using yalls as a rybby ducky nr

rn

[dusk apex]

Is there an error? @deep willow

[frank pumice]

it isnt the for loop

seems that it just isnt happy with multiple colliders

or collider array

one of the two

[dusk apex]

Likely you're looking at two different collections if there are no errors but the element isn't being added.

[muted grove]

Classes that are inheritting another class inherit everything from that class, right? If so, how does Transform inherit Component if Component has a Transform as a property?

[dusk apex]

Also, you ought to use the length of the array rather than some arbitrary value for iteratively accessing members of the array. Else you could possibly get index out of range errors. Or at least constrain i by the length of the array as well.

[dusk apex]

Every object has a transform component. Every component placed on an object will know this transform component - Unity provided to us.

Transform just so happens to also be a component. So it'll have a reference to itself.

Through the inherited Component class

[muted grove]

Objects don't have transforms https://docs.unity3d.com/ScriptReference/Object.html

[dusk apex]

You're referring to members and not components..

An object will always have a transform component

Implies "Unity Game Object"

[muted grove]

GameObjects do

im trying to understand how scripts access references so im going down the inheritance chain

[dusk apex]

The property merely returns a reference of the actual component on the object.

[muted grove]

from https://github.com/Unity-Technologies/UnityCsReference/blob/master/Runtime/Export/Scripting/Component.bindings.cs
is this understandable or is it some internal unity thing

[distant glen]

I've attached my code and a video demonstrating the issue.

The "add item" button places two seeds in the players inventory of a different type.

The code instantiates the panels you see beneath the "plant seed" UI in the GIF image.

The intention is that no matter how many seeds you have in your inventory, only one panel will instantiate per seed, so the screen is not flooded with panels.

However, as the GIF demonstrates, selecting the right-most seed causes a bug where only one panel is instantiated despite multiple seeds being in the player inventory.

Selecting the left-most seed causes the panels to display correctly again. I do not understand.

Full code is here: https://wtools.io/paste-code/bJzl

[west sparrow]

This is something the Unity team has wanted to change for a long time

They finally managed it with rigidbody, but they do have their eyes on transform..

[muted grove]

do you know of any good resources for learning how unity works beside docs.unity3d.com

or do i really only need the docs

[west lotus]

!learn

[tawny elk]

🧑‍🏫 Unity Learn can offer you over 750 hours of free live and on-demand learning content for all levels of experience! Make sure to check it out at https://learn.unity.com/

[muted grove]

most of those are beginner tutorials on how to make template games though, right?

[west sparrow]

I got by with only the docs, but I started in 3.x, and their documentation and tutorials were a lot better at the time

[west lotus]

There are advanced concepts as well. You wont learn the actual internals since well unity is closed source. But plenty of the packages such as the SRPs are open on github

[dusk apex]

I'm not sure what you're looking into or asking, specifically. Properties are simply methods under the hood. In this instance, it returns a reference to the Transform component on the object. I do not know the underlying means of which it acquires the reference. Could probably just assume it caches it once after the component is added to the object or acquires it after first call to the transform property (they aren't likely calling get component for Transform every time the property is used - if so, they need to stop doing so as the Transform of an object cannot change). Knowing what you're concerned about would better help us answer your question. Likely there's some sort of misunderstanding.

[muted grove]

would learning CLR or .NET help with programming in unity or am I just about fine with random searches to leanr.microsoft.com or "learn c# in 4 hours," "this is what delegates are!" kind of videos

if i were to look up how c# handles garbage collection would that be helpful

[dusk apex]

Build your game then profile afterwards.

[muted grove]

alright

thanks

[west sparrow]

Yes, and a bit of no. Traditional .NET uses a lot more static fields, getter/setters and has a different set of patterns overall. But if you were good at .NET, you will learn the Unity way of things much much quicker

blaze.enemyToAttack.gameObject.tag = "Dead";

Is this how I would change a gameobjects tag? Because it's not working?

[west sparrow]

Yes, provided it is a valid tag though mind you

It has to be a tag already specified in the Editor, and caps matters for it

[cinder kindle]

I've created the tag I haven't given it to anything and also i've got the capitalization right and it doesn't work

[west sparrow]

Offhand the code looks just fine to me. I'd assume something else is somehow.kcmkng it

[unreal temple]

is the line being called?

like... put a log after it

or check with debugger

There are probably better ways to store if an enemy is dead btw.

there isn't for the ai framework im using

[opal pine]

Hey guys. Having issues with lists atm and google isnt helping me with this one. It must not be a common issue.
Im getting all colliders with Physics2D.OverlapCircleAll and thats all working correctly but its not putting them into a list in order. Trying to find the first one in the list by foreach (Collider2D col in colliders) {} but watching in the inspector normally the 3rd or 4th collider will get thrown in element 2 in stead of becoming the new element 0. So when I remove an element (out of range) its no longer detecting the next furthest collider.

Is this intended? Doesnt seem to be a common issue that I can find.

[main shuttle]

Physics2D.OverlapCircleAll returns an array, not a list. Lists wouldn't have this problem normally. Can you show your code? Seems very strange.

[opal pine]

Sorry yes its an array. I was working with lists before. Here is the update function.

colliders = Physics2D.OverlapCircleAll(transform.position, range, mask);
        foreach (Collider2D col in colliders) {
            Debug.Log(col.name + " Has been found");
            if (selectTarget == targetSelect.First) {
                currentTarget = colliders[colliders.Length -1].gameObject;
            }
        }
        if (colliders.Length == 0) {
            currentTarget = null;
        }
    }

[main shuttle]

#archived-networking probably. The pins there should help you further.

cs or csharp @opal pine

I don't understand the problem in regards to your story.

if (selectTarget == targetSelect.First) { this whole part is unspecified.
Then you set your target to the last one in the colliders array.

Your foreach seems fine.

[opal pine]

Very sorry for the sloppy screenshot.
As you can see on the inspector I've highlighted the 2nd element but in the Hierarchy its highlighting the last spawned gameobject

[main shuttle]

OverlapCircle don't care about the hierarchy

Why does the order of the hierarchy matter?

[opal pine]

Thats just an enum. I have to select last to grab the first add array. But when that first array goes away its not in order that it gets added

Cause then it will select the next first gameobject.

[dusk apex]

What're you trying to do.. find the closest one?

[opal pine]

just trying to find the first one. But as the array gets smaller I want it to find the next "first" one. Not a random one in the list because its been added in the wrong element

[dusk apex]

What's "first one"?

I'm guessing the one that's in the lead?

[main shuttle]

But OverlapCircle would remove it the next frame anyhow.

[opal pine]

First spawned object. Yes in front

[open thorn]

I got a problem where one of my raycasts returns a false positive. It returns true when it collides with layers not defined in platformLayerMask variable, which is set to default layer in the unity editor.
But the weird thing is that my other raycast doesn't return a false positive...
Anyone knows what the problem could be?

private bool IsBlocked()
{
  RaycastHit2D raycastHit = Physics2D.Raycast(collider2D.bounds.center,               Vector2.right * movementDirection, platformLayerMask);
  return raycastHit.collider != null;
}

private bool IsGrounded()
{
  RaycastHit2D raycastHit = Physics2D.BoxCast(collider2D.bounds.center,               collider2D.bounds.size - new Vector3(0.1f, 0f, 0f), 0f, Vector2.down, 0.2f,       platformLayerMask);
  return raycastHit.collider != null;
}

[dusk apex]

Put some value on each object, then you'd be able to evaluate that object to see who's the highest priority

[main shuttle]

if (selectTarget == targetSelect.First) { this is either true for everything in the array or for none, it also uses nothing of what you are iterating over. So the foreach also doesn't make sense.

[dusk apex]

Else you'll need to have some way to weigh which object is first.

[opal pine]

public enum targetSelect {First, Last, MostHealth, LeastHealth, MostArmour, LeastArmour, MostShield, LeastShield}
    public targetSelect selectTarget;

That if (selectTarget == targetSelect.First) has nothing to do with the array being added. I just didnt think when you add something to an array it would be added in a random spot

[dusty gulch]

Hello guys
The main branch is old and it has alot of glitches so i want to delete it and make (The-work) branch to be the main branch
i dont whant to merge it becuase the main branch is very old and alot of glitches

[main shuttle]

So if your point is that the order of the array that Physics2D.OverlapCircleAll gives is unspecified, you are right.

[opal pine]

Well that doesnt help me haha. Its so weird that it just wouldnt add any new elements in the array at the end or the start.
Guess Ill have to do a check that grabs all objects then checks each one with distance rather then relying on it being added in order that is finds the colliders

[main shuttle]

No it's not weird. You are dumping away the array and making a new one each frame. Then it scans the world again for colliders. It maybe has some scan order, don't know about the internals, but if it scans from top left to bottom right, the triangles will still switch places all the time.

[opal pine]

well that makes sense. And I thought this was going to be easy

[main shuttle]

Well, what I would do is give the enemies an enemy script. One of the values is how far they are on the path. Get the biggest number for the First.
Inverse it for Last. Enemy script also has values for Health, Armor and Shield. foreach over it and make a choice on that.

[main shuttle]

https://docs.unity3d.com/ScriptReference/Physics2D.Raycast.html

public static RaycastHit2D Raycast(Vector2 origin, Vector2 direction, float distance = Mathf.Infinity, int layerMask = DefaultRaycastLayers, float minDepth = -Mathf.Infinity, float maxDepth = Mathf.Infinity);
You dump your layermask value into the distance.

What's a quick way to generate a mesh along a spline? A simple flat thing like a road will do.

My current code is

Mesh GenerateMesh()
        {
            Mesh outMesh = new();
            List<Vector3> verts = new();
            int pointsRange = ((int)math.floor(container.Spline.GetLength() * 10));
            for (int i = 0; i < pointsRange; i++)
            {
                container.Spline.Evaluate(i / pointsRange, out var pos, out _, out var up);
                verts.Add(pos + (up * grabLength)); //Add far point
                verts.Add(pos); //Add point on spline
            }
            int[] tris = Enumerable.Range(0, verts.Count - (verts.Count % 3)).Select(x => x).ToArray(); //The mod is to cut off the last triangle if there arent enough points
            outMesh.vertices = verts.ToArray();
            outMesh.triangles = tris;
            return outMesh;
        }

I am purposefully generating it only to one side

[simple mountain]

if that works that s pretty quick

[elfin vessel]

I'm making a mesh for a Gizmos Drawmesh here, but I can't find it anywhere in my scene, so I can only conclude im not doing somethign right

I also tried wiremesh in case it was being affected by backface culling

[simple mountain]

I've never used gizmos.drawwiremesh I would try

• Debuging the outMesh.vertices.Length
  -Creating a mesh and looking at it in scene view with wireframe on
  -Writing out every point of the mesh and check if something is fishy

[elfin vessel]

I’m take a better look tomorrow

How can I access the animation state from my animator through script, so that I can modify its speed?

[mossy snow]

enable parameter checkbox, set parameter via script

[deft timber]

No need for parameter checkbox for just modyfing the speed

animator.speed

[mossy snow]

that will affect all states

[deft timber]

animation["Idle"].speed for example

[mossy snow]

hmmm I think the animation clips are shared, so that would probably modify the clip's speed for all animators that use that state. I haven't tried that though

[deft timber]

Yea if you are using the same animation clip attached to different object i believe it'll modify the speed in both

[coral kettle]

does anyone know how I would do this? I have a value "20". I have another value that I will call "balance". what I want to do it lower 20 by 1 for every power of 10 "balance" that I have

in C# that is

[lucid valley]

//initialValue is the 20
initialValue -= Mathf.FloorToInt(Mathf.Log10(balance));

i think that should work

I am getting "NullReferenceException: Object reference not set to an instance of an object Player_Movement.Update () (at Assets/Scripts/Player_Movement.cs:28)"
with the line that references like
if (Input.GetKeyDown(KeyCode.LeftControl) && CoinScript.CoinCounter > 5)
{
RUN = 2f;
CoinScript.CoinCounter -= 5;
Invoke("Walk",RunTime);
}

I referenced the CoinScript

I have referenced it in the editor

[lucid valley]

line 28 the if?

[near crown]

and I still get this error

ya

[lucid valley]

you sure you are not changing CoinScript anywhere in code?

[near crown]

In what sense?

[lucid valley]

CoinScript =

or is it just being set in the inspector

[near crown]

I putted at the start CoinScript = GetComponent<Coin>();
just for autonomation

[lucid valley]

so does the gameobject that has the Player_Movement also have the Coin script?

[near crown]

Also what I'm trying to do is accessing a variable in the script

[near crown]

No

they're separated

[lucid valley]

....then that is why it is erroring

GetComponent<Coin>() is returning null as that script isnt on that gameobject

[near crown]

UH I understood!

I should have done FindObject not component!

Ty now it works!

[coral kettle]

I'll try it out, thanks!

[warm tendon]

hi, i'm trying to procedural generate a map but i'm having problems with adding colliders, when i add a mesh collider it just goes like this

[agile plaza]

how difficult is the input system to learn ?

[oblique spoke]

https://docs.unity3d.com/Packages/com.unity.inputsystem@1.5/manual/HowDoI.html

Don't crosspost.

[agile plaza]

Thanks

I am new to this and I am making a game for the global games jam

[dusky lake]

Did you reference the mesh in the mesh collider mesh property?

[warm tendon]

i did something, no idea what, but it's fixed now, thanks for responding though 👍

also i think that i had put the mesh in the mesh collider property but again, i have no idea what i did

[vagrant agate]

It will depend on your ability. I just switched over my game from the old system to the new system over a couple hours yesterday.

[deft cairn]

Hello, is there a way of change color of the child image (Icon) when I hover the parent Buton?
Right now it changes the green circle color when I hover, but I also want to change the leaf icon color

[agile plaza]

How can I make a simple player character movement with old input system ?

Performance of collider without rigidbody vs collider with static rigidbody?

[somber nacelle]

there are quite possibly hundreds of tutorials that show you how to do that

Hi guys! can someone help me to convert an image? unfortunately I don't know how to program 😭 thanks

I need to convert a .texture2D file to .exr

Pretty sure it was set to convex earlier

[next crypt]

Hello, I want to create a static function that can be called by any class, it is supposed to compare the tag of something of any possible type to another tag and then basically assign something to another thing, no matter the type. As an example, I have the function

       if (tmproText.CompareTag(TagsManager.AchievementNameTag))
           {
               tmproText.text = achievement.Title;
           }```
i'd want to create a static function that looks like:
```cs
   void CompareAndAssign(firstThing, string TagToCompareFirstThingTo, thingLeftOfEqual, thingRightOfEqual)
   {
       if(firstThing.CompareTag(TagToCompareFirstThingTo))
       {
           thingleftOfEqual = thingRightOfEqual;
       }
   }```
So in my example, I'd basically only have to call CompareAndAssign(tmproText, TagsManager.AchievementNameTag, tmproText.text, achievement.Title)
However, I have no idea how this is possible, help would be very much appreciated, thanks in advance 🙂

Thanks, thought it only needed the cs 👍

[rain minnow]

your static method does not have types for 3 of the parameters . . .

[next crypt]

yeah, cause I want to create a function where I can input things of any possible type into it, is that possible and if so, how?

[rain minnow]

those params need to be of a type that are compatible . . .

everything derives from object but you'd have no idea what the actual type is. you can't confidently assign one value to another with receiving errors if they're aren't the same type . . .

you need to constrain the type to smth all of your input will have in common . . .

you're main goal is to compare tags. tag is a GameObject property, so why not use that type?

[next crypt]

do you happen to know if textmeshpro for example is derived from gameObject, thus if I use gameObject for my type, would it work with textmeshpro

[rain minnow]

no, it's not, and you can easily look that up . . .

that doesn't make sense; TextMeshPro is a component . . .

you can see that from your inspector . . .

[next crypt]

So what can I do in order that my function works?

    void CompareAndAssign(object firstThing, string TagToCompareFirstThingTo, ref object thingLeftOfEqual, object thingRightOfEqual)
    {
        try
        {
            if (firstThing.CompareTag(TagToCompareFirstThingTo))
            {
                thingLeftOfEqual = thingRightOfEqual;
            }
        }
        catch
        {
            Debug.LogWarning(thingLeftOfEqual + " can not be assigned to " + thingRightOfEqual);
        }
    }

Based on what you said I tried to adjust my function, I decided to use object as GameObject is not compatible, like you stated, however how can I use CompareTag with the class object, is there and thing like firstThing.TryGetComponent<GameObject>(), that might be possible?

[distant bloom]

dawg wtf I dont even remember joining this server

☠️

[next crypt]

Wait, just relized I could just input tmpro.gameObject instead of just tmpro, thus gameObject is a viable option as my first parameter

[rain minnow]

that's what i mentioned earlier . . .

i said using object doesn't make sense because you don't know what the actual type is that you are passing in . . .

[warm night]

Hey, how can i change without script the transform of a child gameobject without changing his parent's transform..? It doesn't work for me ! :/

[potent sleet]

animation

[next crypt]

Yeah, just didn't see how that would work with things like TMProText at first, but I can just use TMProText.gameObject, object would work as 3rd and 4th parameter though, wouldn't it?

[warm night]

fr ?

[rain minnow]

@next crypt what if the first param is a GameObject and the second param is a c# class? they're not compatible . . .

[potent sleet]

or use the inspector idk

[warm night]

i have the case in another scenes, and it works pretty well in the inspector, but not on another scene, it's so weird

[rain minnow]

the child can move independently of its parent. you can use code or an animation . . .

[next crypt]

the second is a string because it is always only used in the brackets of comparetag()

[warm night]

And without code?

[potent sleet]

idk ur asking something about without code in a code channel

[warm night]

yeah ikr :/

i'm gonna try to find out

thanks anyway

[rain minnow]

i gave an answer for without code. read my message again . . .

[warm night]

Yeah but in another scene, i'm not using animations, or code and i can move the child independently in the inspector, but not on my current scene, that's weird xD

[rain minnow]

i see that, but why are you assigning one variable to another? what is that for?

[rain minnow]

huh, this doesn't make sense? how do you expect to move smth if you don't use code or the inspector to animate it? i don't follow what you're trying to do . . .

[swift falcon]

Where is player model at?

[next crypt]

I basically want to assign a value to another value if compareTag returns true, but on top of that do lots of other stuff if compareTag is true, in order to write less code I want to create a function that assigns thing1 to thing2 and does all the other stuff below

[next crypt]

The function seems to work now btw, thanks for the help! 🙂

[warm night]

I mean, i just want to move it in scene view, like drag my child to move it downwards xD, i can show u screenshots if you need

[rain minnow]

okay, but don't use try/catch, just log if the statement isn't true . . .

[warm night]

I mean, the child object is "local" to parent, and i don't want that

[rain minnow]

then don't make it a child . . .

that's just how parenting works . . .

[next crypt]

that isn't really used for checking if the statement isn't true, but instead checking if thingLeftOfEqual and thingRightOfEqual is compatible, however I just realized that if it isn't compatible, an error appears in visual studio anyway, so try is unnecessairy

[warm night]

i swear that i have another parent, which i can move independently the child on inspector, without affecting his parent, thats' why i'm writing here xD

[rain minnow]

yup . . .

[rain minnow]

a child can always move independently of its parent . . .

moving a parent will affect the child . . .

[warm night]

the first screen is the position of the player, and the second one, it's the position of the player after moving up the "graphics" child to the good Y pos

i swear it's weird bro

ok for some reason i just redid the manipulation as i did just for the screens, and it works

wtf

i'm not drunk xD

[rain minnow]

not sure what the problem is. you're probably just bugging, but ask in #💻┃unity-talk as this isn't a code question . . .

[warm night]

Yeah it was bugging

Hello, I don't know if this is the correct channel to post my code for review but I feel like I'm doing some stuff wrong (performance wise) with this code, I'd appreciate if anyone can pinpoint any bad practices in my code!

hello guys so i just finished watching a video about headbobbing and in the video the headbobbing is normal but mine is like this:
this the code that does the headbobbing:

private void HandleHeadbob()
    {
        if (!characterController.isGrounded) return;

        if (Mathf.Abs(moveDirection.x) > 0.1f || Mathf.Abs(moveDirection.z) > 0.1f)
        {
            timer += Time.deltaTime * BobSpeed;
            playerCamera.transform.localPosition = new Vector3(
                playerCamera.transform.localPosition.x,
                defaultYPos + Mathf.Sin(timer) * BobSpeed,
                playerCamera.transform.localPosition.z
            );
        }
    }

[leaden ice]

I would bet dollars to donuts that in your video:
Mathf.Sin(timer) * BobSpeed
is actually
Mathf.Sin(timer)
or
Mathf.Sin(timer) * BounceAmplitude < which is what you should do here to change the amplitude

Remember BobSpeed is already taken account of with this: timer += Time.deltaTime * BobSpeed;

[pine bronze]

this is the code from the video he uses the ternary operators there but i chose to put it in the BobSpeed variable but my code is exactly the same as the one in the video

[leaden ice]

no it's not

again

like I said

you're using bobSpeed there

he's using bobAmount there

different variable

[pine bronze]

oh

[dawn dock]

Hey so I've made a health system, mostly, but I'm struggling to add immunity for a certain amount of time after being hit. https://gdl.space/gicolawemi.cs Can anyone help?

[pine bronze]

now the headbob doesn't work at all

[leaden ice]

what did you set bobAmount to

and what code did you end up with

debug it

[pine bronze]

this is the code now:

if (!characterController.isGrounded) return;

        if (Mathf.Abs(moveDirection.x) > 0.1f || Mathf.Abs(moveDirection.z) > 0.1f)
        {
            timer += Time.deltaTime * BobAmount;
            playerCamera.transform.localPosition = new Vector3(
                playerCamera.transform.localPosition.x,
                defaultYPos + Mathf.Sin(timer) * BobAmount,
                playerCamera.transform.localPosition.z
            );
        }

and these are the bobbing amounts

[leaden ice]

why did you switch timer += Time.deltaTime * BobAmount; to use BobAmount???

this is really just you not being careful and not copying the code properly / paying attention to what you're doing

[pine bronze]

yeah sorry it works now

[spring bobcat]

Hello, I'm having a problem with getting my Player to the next scene. I put everything how it's supposed to be but still nothing is working, I don't know if I missed something or if something is wrong with the code.
(I put the Is Trigger on the object the player has to go through, and I put the scenes is build settings)

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;

public class SceneRight : MonoBehaviour
{

    private void OnTriggerEnter(Collider other)
    {
        if (other.CompareTag("Player"))
        {
            int sceneBuildIndex = SceneManager.GetActiveScene().buildIndex;
            SceneManager.LoadScene(sceneBuildIndex + 1);
        }
    }
}

[leaden ice]

add Debug.Log outside the if statement to see what's going on

This is where you start debugging

Debug.Log($"Collided with {other.name} with tag {other.tag}");```

you can't just stare at code and guess. Debugging is the only way forward

[dawn dock]

Can anyone help me with this

[rapid brook]

Code?

[dawn dock]

https://gdl.space/gicolawemi.cs

[leaden ice]

you'd have to actually tell us what's going wrong

[dawn dock]

I tested the immunity frames to be 100 on start, and the immunity frames went straight down to -0.02 in the console

[vagrant agate]

start a coroutine that waits X seconds and have a global boolean or use enums to track whether you should be immune

[rapid brook]

I assume you want to start a Coroutine after the character was hit that would trigger a variable "isImmune" and make it true , then after a certain amount of time, make it false again then in your collision system you check If isImmune is false

[dawn dock]

Yeah

Thanks Ill try that

[leaden ice]

your code is saying "frames" but I think you actually mean "seconds"

you need to figure out which one you want.

and frames is probably not it

[dawn dock]

Yeah Im looking for seconds

[leaden ice]

get it straight in your head what you're dealing with

and make your code reflect that and clearly state it

to reduce confusion

[dawn dock]

Yeah my bad

[rapid brook]

Also, in your Coroutine don't use Wait for seconds, If you pause the game by making the Time.timescale = 0, your Coroutine will still run and set the bool back to false after the set amount of time

[vagrant agate]

you can def use waittforseconds. be smart be aware of your coroutines

store it or use StopAllCouroutines on the behavior

[rapid brook]

Using waitForSeconds is not a good idea if the game has a pause system, which most likely has, it's better to use WaitForFixedUpdate and have a value that increments until it reaches the amount of time the player should be immuned for

That, is considering the pause system just set the TimeScale to 0

[summer pecan]

That’s how the model is, if the X is 0 they’ll be on their faces but if it’s -90 they’re standing up

[rapid brook]

Something like this :

don't forget to add a yield break if the player is already immune, better safe than sorry

[slender helm]

Is there a proper way to transfer ownership of network game object from client to host and in opposite ? For some reason with this code I am getting, Client wrote to NetworkVariable ... without permission, Why I am getting this error, (I am trying to transfer ownership via Server rpc) ?

[swift falcon]

Hello i got this error in Google Play Console After trying to upload an aab file:

APK or Android App Bundle which has an activity, activity alias, service, or broadcast receiver with intent filter, but without the 'android: exported' property set. This file can't be installed on Android 12 or higher. See developer.android.com/about/versions/12/behavior-changes-12#exported

[rain minnow]

You're adding deltaTime but using WaitForFixedUpdate which relies on fixedDeltaTime. The added deltaTime value is not consistent with the next iteration (call to run the coroutine) . . .

[rapid brook]

Oh, then replacing deltaTime by fixedDeltaTime should do it? I wasn't aware of that

[rain minnow]

yeah, but there are many different ways to do it. they can yield return null; and use deltaTime. if timeScale is set 0, it will not add anything to the timer (variable), resulting in a stalled state for the coroutine (paused). you can also set the keepWaiting property to suspend the coroutine. using WaitForFixedUpdate means you're relying on FixedUpdate, but that should only be used for physics-based code (unless you're doing smth deterministic) . . .

[rapid brook]

Yeah my first approach was to use yield return null coupled with incrementing the number with time.deltaTime, but then when I saw I could just wait for the fixed update it seemed to be more appropriate, guess it works, but didn't know it kept running the coroutine, I though it really just was waiting for the next fixed update

[rain minnow]

if they do want the coroutine to run while paused, they'd use the Realtime version of the yield instruction . . .

[rain minnow]

you can use WaitForFixedUpdate to wait for the next FixedUpdate but the deltaTime added needs to be correct. that's all i was mentioning . . .

[rapid brook]

Okay, so it means the deltaTime is not 0 when TimeScale is 0?

I don't get it, it has to stay at 0 since the value doesn't increment anymore when timeScale is 0

And since it's a delta, it has to be some sort of interpolation between one moment to the other? So deltaTime is not going to change by much?

Or am missing something?

[rapid axle]

Hey yall, I have a ton of animations and I dont want to set them all up in an animator, is there any way I can change blend tree animations through script on runtime?

[potent sleet]

https://docs.unity3d.com/ScriptReference/Animations.BlendTree.html

I'm guessing "AddChild"

[rain minnow]

No, didn't say that. deltaTime will return 0 when timeScale is 0. If you add deltaTime to the timer and wait until the next FixedUpdate — the deltaTime between fixed updates are constant at 0.02 which is different from the deltaTime you added to the timer (since it's at a variable rate) — the value is not consistent when the caller returns to the coroutine . . .

[dim whale]

Hey, I have next to no experience with animations, but I would check out iHeartGameDev. He has generally very good tutorials, including animations.
For scripting animations I hear Animancer is a good alternative, but I have no idea if that's an up-to-date opinion.

[idle meteor]

Hello everyone! I'm having a problem with Unity and still haven't found the solution. When I first start my game, there is a very short freeze while rendering any UI element. Sometimes this can be in milliseconds, sometimes it can be in seconds. What could be the reason for this?
https://youtu.be/-wbs0EYGkgA

[glad shoal]

how can I install this package? https://docs.unity3d.com/Packages/com.unity.nuget.newtonsoft-json@3.0/manual/index.html

[rocky void]

Unity is executing all of your start/awake functions, the UI renderer is just trying to keep up with everything else going on. If you have a game manager you would generally load all of your assets in before anything renders and the player can move

[idle meteor]

So how can I preload all the items? Sorry, I'm very new to Unity.

[wintry stone]

I just switch over to the new unity input system and Im having trouble converting my code would anyone know how to get this if statement to work?
if (context.performed)
{
jumpBufferCounter = jumpBufferTime;
}
else
{

        jumpBufferCounter -= Time.deltaTime;
    }

[rocky void]

A game manager and game loop is a bit harder to explain if you're new to unity but do have a look at the SOLID principles and learn about different programming patterns. It's a lot but will help your coding in general to be more efficient and extendable. For now have a look at this, it looks like Unity can preload selected assets and make them available in memory from the start of the game: https://forum.unity.com/threads/how-does-preloaded-assets-in-player-settings-work.318259/

[vestal crest]

        return list[^1];
#else
        return list[list.Count - 1];
#endif```

is this syntax okay?

[rocky void]

take a look at this too, it breaks down patterns and best practices pretty well https://blog.unity.com/games/level-up-your-code-with-game-programming-patterns

[dull merlin]

mb yo

[kind wolf]

do canvases work when instantiated?

[somber nacelle]

yes

[kind wolf]

specifically if it has a button

because i instantiated a canvas with a button and it doesnt work

[somber nacelle]

is there an event system in the scene?

[halcyon thorn]

I am having trouble finding the cause of a pathfinding issue with my NavMeshAgent.

Goal: find the shortest NavMeshPath to the Vector3 target
Problem: when the target (my player character) is in motion, the pathfinding returns a NavMeshPath. If the target is not in motion, it returns null.

I use the following method to find the shortest path to the player position:

private NavMeshPath GetShortestPath(Vector3 target)
{
  var path = new NavMeshPath();
  if (NavMesh.CalculatePath(transform.position, target, _agent.areaMask, path))
  {
     return path;
  }

  return null;
}

Has anyone encountered this problem or has any ideas what I can do to find the issue?

[kind wolf]

yea

[halcyon thorn]

Use Debug mode with the Event System selected and see where what the active object is.

Common issue is that you did not have a GraphicsRaycaster component on the Canvas

[kind wolf]

oh wait

i dont have an event system

im assuming thats the issue lol

[dull merlin]

so i need to animate a button on my main menu to smoothly scale up when hovered over and smoothly scale down when the mouse exists, i tried using animator to record a scale up and scale down- but im not able to figure out how to make the animation only run once and stay on the ending keyframe while the mouse is hovering over the collider, as well as scale down and stay on the regular scaled down keyframe after the mouse exits the collider

Animator animator;
    public bool mouseOver = false;

    void Start() {
        animator = GetComponent<Animator>();
    }
   void Update()
   {
       if(mouseOver==true)
       {
           animator.SetTrigger("MouseEnter");
           animator.ResetTrigger("MouseExit");
       }
       if(mouseOver==false)
       {
           animator.ResetTrigger("MouseEnter");
           animator.SetTrigger("MouseExit");
       }
   }
    public void OnPointerEnter(PointerEventData eventData) {
       
        mouseOver=true;
    }

    public void OnPointerExit(PointerEventData eventData) {

       mouseOver=false;

    }
}

btw

does anyone else have issues with the input system or am i just dumb

[halcyon thorn]

describe the issues

[somber nacelle]

"have issues" is incredibly vague.

[kind wolf]

im just asking in general cuz like

ive had to do a lot of bs to get it working

for example

[halcyon thorn]

I am not a huge fan of it personally, I think it can be easier but it's okay now that I have done it many times

[kind wolf]

i have an instantiated player and the player gets disabled through gameplay so i cant have a player input on it

[halcyon thorn]

this is a design issue

[kind wolf]

lol is it

[halcyon thorn]

you can put player inputs on a different object

[kind wolf]

yea i did that

i put another object in the player prefab that sets its parent to nul

but it just feels so weird

to do that

[halcyon thorn]

you could have it as a separate prefab

[kind wolf]

i just wanted to know if i was bad or if everyone has to deal with new input system bs

[halcyon thorn]

oh is this the new input system? I haven't used it extensively

[kind wolf]

yea

[somber nacelle]

still sounds like a design issue tbh

i use the input system exclusively and have never run into issues like that. you just need to learn how it works so that you can use it effectively

how is it a design issue tho?

[halcyon thorn]

in my current project, I have a Player GO that exists throughout the game that stores all things related to a single player (my game is multiplayer). Then, PlayerCharacter is a separate object that receives only the inputs it needs

[kind wolf]

like what else am i supposed to do?

should i not disable the char or smth?

[halcyon thorn]

what is the issue exactly and what are you trying to accomplish?

[somber nacelle]

i mean you haven't really even described the actual issue. you've just said you cannot put the player input component on the player object because you disable the player. but why is that an issue

[kind wolf]

i mean there isnt an issue because i did the weird workaround

maybe its just a personal thing idk it feels weird to do something like that

is there a way to append functions to player input events?

[somber nacelle]

well considering you haven't even said what the issue was then nobody here can possibly know what you actually need to do

[halcyon thorn]

yeah I'm not sure what you are trying to do and what issue you are working around

i might be rambling a bit sorry lol
