with the physics engine?

#

Your collider for the player if you have a box, have it not as low down

#

It would be easier to adapt your character to the tiles than get the tiles to remake a collider each time you add or take from it

balmy vortex
#

hey so like how would you go about increasing the transform size of a particle system?

winged ridge
balmy vortex
#

I need to expand the particle systems whenever the object they're on touches smth

#

I have the collision detection and stuff all figured out but idk how to actually expand them

charred monolith
#

!code

radiant voidBOT
charred monolith
# balmy vortex well yeah but I mean like through a script

I maybe found a code but idk if that works as u wanted. but maybe u can understand the code and change it.

float scale = 0.3f;
var psys = GetComponentsInChildren<ParticleSystem>();
foreach (var ps in psys)
{
    var main = ps.main;
    main.scalingMode = ParticleSystemScalingMode.Local;
    ps.transform.localScale = new Vector3(scale, scale, scale);
}

and how to fix it

naive pawn
#

how are you moving it?

#

!code

radiant voidBOT
charred monolith
analog pendant
#

float VMove = Input.GetAxis("Vertical") * MSpeed * Time.deltaTime;
float HMove = Input.GetAxis("Horizontal") * MSpeed * Time.deltaTime;

//Player Movement

Vector3 PlayerMovement = transform.forward * VMove + transform.right * HMove;
player.Translate(PlayerMovement);

naive pawn
#

does your player have an RB

analog pendant
naive pawn
# analog pendant yep

move your player via the RB instead. the RB will try to control the transform, so you're fighting it.

hello, i have a really shitty problem with GUI

#

idk if any of you ever encountered this problem

analog pendant
#

with the respect to the camera

timid ocean
#

but for some reasons i can't click any GUI button

#

my colleagues have the same exact projet (and i got their project from a zip)

#

but for some reasons i can't click GUI buttons

naive pawn
naive pawn
timid ocean
#

let me record a quick video

#

my english sucks so i'd better record smth

charred monolith
timid ocean
#

i know my scripts are working fine

#

and even if both GUIs overlap each other

#

it shouldn't be a problem

balmy vortex
#

hey so like how do you change the transparency of a material?

timid ocean
charred monolith
timid ocean
#

i tried literally everything

#

cleaned Unity's cache

#

re installed the entire unity editor

#

switched to my colleagues' project

charred monolith
balmy vortex
#

yes I know I meant though a script

timid ocean
#

you can't directly do it i guess

#

you should go through a renderer

balmy vortex
#

I need to change an objects transparency over time

naive pawn
charred monolith
naive pawn
#

Update -> LateUpdate can fix jittering on cameras due to the update order and getting fresh info for the current frame

#

this is not that case

#

the jittering here is due to fighting the RB for control of the transform

Good morning, I'm a beginner with Unity programming. It would be great if someone could coach me or help me how to start with Unity. If someone is interested in helping me, send me a message.

How do I access sprites from a spritesheet through code using a number index? As in, individual slices from here.

I'm mostly asking about what is this called internally

naive pawn
charred monolith
#

ive never worked with scrollbar its my first time

finite briar
#

Hello, the first thing is that you completely disregard the its original y position

#

i would reccomend to save the initial position on start and than offsetting based on that

charred monolith
tall heart
#

Anyone know how to escape tutorial hell?

finite briar
#

At least what helped for me:
not following the tutorial

#

not in the sense of just not watching them but kind of always not doing what they tell you

#

they use an array, you try to make it work with a list, they suggest 2 instances you use 3, they use something that isnt 100% part of the tutorial, you ignore it

#

and always try to learn tools, not solve problems (so how to use blender instead of how to make a brick)

#

hope that helps

#

Thanks man

its actual a small lagspike but yea

You're adding a new listener every frame. It should be Start or Awake not Update

Does anyone know of a direct way to use Unity recorder while excluding certain layers? Similar to how camera culling works

# timid ocean

try changing ur scale to something static instead of Free Aspect

#

my guess is Resolution / Scaling Mismatch

anyone here familiar with webgl?

i might have heard of it.. whatsup?

#

im using itch.io to host my game, but im getting errors in the inspect console that don't appear in the unity editor

#

specifically a null reference exception error

timid ocean
#

the issue was the game being paused 🤣

#

which highlighted another issue

#

the game is randomly getting paused on some operations

Hello!

Could someone help me with this error, thanks!

This happens

#

More errors

timid ocean

just to figure out the game was paused 🤣

#

i think i found out a solution

Could anyone please help me, thanks!

rule #5 :
if it compiles, so be it. ignore the remaining errors 🗿

timid ocean

read carefully

# alpine heron

Looks like the asset is using some outdated api, if its not yours try to update it

rocky canyon
# timid ocean i spent 2 days on this, nearly kicked my computer out

tbh thats usually teh case..
suprisingly the more complex problems end up being easier to spot
its the stupid silly stuff that goes unnoticed..

the thing i remember the most is having no idea why my project folder would show as empty.. but it was b/c i had accidently left something in the search bar

#

especially when its a big honking project w/ dependencies Everywhere!

timid ocean
#

so yea i got some errors because of initialization speed

#

but nothing concerning

#

on top of that i use scriptable objects

#

yea next time i’ll just write my own physics i guess

#

we are close to release m

digital stone
#

i have some sprites that i divided
how do i chain them for animations

timid ocean
#

so it’s too late now

slender nymph
#

intentionally allowing runtime exceptions to be thrown because you can't be arsed to actually address the underlying issue is just bad design

timid ocean
#

it is a bad design i’m aware of that m

timid ocean
#

for now it works and doesn’t eat performance i’m fine with it

https://www.youtube.com/watch?v=atW7Ib2sbTw if u end up needing another one this one is pretty epic once u get it setup and working

(its an older project so theres a few errors to fix, n setting up the layers n whatnot)
i used it b/c it has a decent suspension setup and i could just drop my own car model/bodies on top of the prefabs

And what would be the step-by-step process.

grand snow
rocky canyon
#

either that or go in and comment out the code thats causing the error a bit at a time until they're gone

grand snow
#

Its last update was in 2016 so no wonder its broken

timid ocean
grand snow
#

@alpine heron So the problem is that this asset pack is soo old that some included code is broken on modern unity versions. You can try to remove other stuff and keep only the models + textures + materials you need. OR you find something more recent that does not cause such problems.

timid ocean
#

i mean we used an asset that has deformation included

#

i mostly scripted the customization system

#

but honestly it’s a workaround rather than a complete system

#

next time i’ll create one from scratch

#

i started unity in march so still a lot to be learned

#

some aspects are still a total wonder for me

rocky canyon
# timid ocean is it randomizing vehicles bodies?

nah, its just a bunch of different presets
fast car tight suspension
big truck lose suspension
drag car low steering control
drift car high steering control

randomation is just teh guys studio or username

timid ocean
#

ohhh okay

slender nymph
timid ocean
#

well our system is a n wheels system

timid ocean
#

maybe because it’s not my job to fill those scriptable objects?

#

and it’s just a work in progress?

slender nymph
#

you're just so full of excuses for why you can't just go and fix what is likely just a basic NRE lmao

timid ocean
#

i had the pause issue while debugging

timid ocean
rocky canyon
#

it is easy enough to fix NRE's if the project works already and the code isnt anything you need
you can go in and comment out the bits of code that are trying to reference things that no longer or dont exist

but ofc. im a you do you i'll do me kinda guy.. so whatever works for you 👍

slender nymph
timid ocean
#

well you don’t know the story then

alpine heron
timid ocean
#

i didn’t know i had that pause option activated

alpine heron
#

Thanks!

#

I'll find a different one

timid ocean
#

since those errors never really prevented the system from working i didn’t pay attention to it

slender nymph
rocky canyon
timid ocean
#

one was because i used a debug scene

alpine heron
slender nymph
#

"nothing is working"

multiple errors
"i'll ignore that"

timid ocean
#

the other one being a missing reference in a scriptable object

timid ocean
#

yk i won’t argue

alpine heron
timid ocean
#

okay daddy i’ll fix my errors

#

im done

rocky canyon
grand snow
#

hopefully you understand how folders work

rocky canyon
#

or u can Uninstall it via the Package Manager just like you installed it

grand snow
#

not possible for most asset store stuff remember

timid ocean
#

he can probably just replace the depreciated method tho

#

and make it work

rocky canyon
#

ya, 💯 box and i both already mentioned

grand snow
#

10 year old image effect stuff is surely broken or trash anyway

slender nymph
rocky canyon
#

ohh rob yea

grand snow
#

hello

rocky canyon
#

lol

#

ahhh i remember this one..

image.png
#

yea it is a decent asset pack tbh

#

u can still use the scenes and stuff and just remove the image effects
which is likely the volumeteric lights and fog stuff maybe
can add that back in later w/ up-to-date stuff

#

lookie here

image.png
alpine heron
rocky canyon
#

its that script and the DepthOfField.cs script that both have errors it appears from the thread

alpine heron
#

Is there another one withone problems?

#

And free

rocky canyon
#

theres a few.. actually i was just saying that asset is pretty solid (visually)

alpine heron
#

Could you possibly tell me the name of one, thanks!

rocky canyon
#

look thru these

rocky canyon
#

but in all honesty i would grab those for the textures, brushes, trees etc
and then venture out and learn Unity's Terrain component
you can make some pretty awesome stuff if u have all the parts that you need

alpine heron
#

Ok, thanks!

tall heart
#

can anyone help :if (isGrounded && Input.GetKey(KeyCode.LeftShift))
{
speed = speed * 1.2f * Time.deltaTime;
}
else
{
speed = 7f;
}

#

for some reason it doesnt move faster

#

and just stays in place and shows and apsurd number like 1028389e-192 on the speed

slender nymph
#

the only increase in the speed variable here is when it switches from not holding the shift key so that speed gets assigned to the value of 7. Time.deltaTime is less than 1, do you know what happens when you multiply a number by a value less than 1?

tall heart
#

how could i fix it?

slender nymph
#

rethink your logic and think carefully about what exactly you want to happen here

tall heart
#

nvm then

rocky canyon
# tall heart how could i fix it?

to keep it easy to understand you should use 2 variables

normalSpeed
finalSpeed

finalSpeed = normalSpeed;
---
finalSpeed = normalSpeed * 1.5f;
---
Move(direction * finalSpeed * Time.deltaTime);

also, you wouldn't actually need to scale it anywhere but the Move function (the last place you use it)

I am working on a traffic system.

I have a ScriptableObject that holds a list of nodes, each node gets assigned a unique ID by an editor script when I place them. The nodes each have a list of possible previous and next nodes stooring only their unique ID to reduce memory usage. Because their may be up to 50k nodes at any given time.

[System.Serializable]
public struct RoadNode
{
    public Vector3 position;
    public int ID;

    public List<int> nextNodes;
    public List<int> prevNodes;
}


public class RoadGraphAsset : ScriptableObject
{
    public SerializableDictionary<int, RoadNode> nodes;
}

At game startup the game will load all RoadGraphAssets from asset bundles and insert each RoadNode into a SpatialHash that I can use to query an area and get all nearby RoadNodes. Which I can use to determine what nodes to "spawn" cars at

# 
public struct Cell
{
    public int x;
    public int z;

    public static Cell FromVector3(Vector3 v, int cellSize)
    {
        return new Cell()
        {
            x = ((int)v.x) / cellSize,
            z = ((int)v.z) / cellSize
        };
        
    }
}

public class SpatialHash
{
    public Dictionary<Cell, List<RoadNode>> nodes;

    public Cell Insert(RoadNode node)
    {
        var cell = Cell.FromVector3(node.position, 100);
        node.cell = cell;
        if(nodes.ContainsKey(cell) == false)
            nodes.Add(cell, new List<RoadNode>());

        nodes[cell].Add(node);
        return cell;
    }

    public void QueryArea(Vector3 pos, ref List<RoadNode> results)
    {
        if (results == null) results = new List<RoadNode>();

        var baseCell = Cell.FromVector3(pos, 100);

        // Visit current cell + surrounding cells
        for (int dz = -1; dz <= 1; dz++)
        {
            for (int dx = -1; dx <= 1; dx++)
            {
                var c = new Cell { x = baseCell.x + dx, z = baseCell.z + dz };
                if (nodes != null && nodes.TryGetValue(c, out var list))
                {
                    results.AddRange(list);
                }
            }
        }
    }
}

is this a decent way to handle something like traffic simulations?

# 
var cell = Cell.FromVector3(node.position, 100);
        node.cell = cell;

also curious is this valid since RoadNodes are structs and not a class I hear we are not meant to mutate them but the compiler lets it happen.

For your last statement, you could probably just create a constructor accepting your v3 and cell size etc

The x and y members aren't static so if you believe you're modifying the default values of the type, you aren't.

{
    public Vector3 position;
    public int ID;
    public Cell cell;

i definitely dont think copying this everytime I need to modify cell is going to be faster than just using a class

#

Just for clarity, it should be understood that SOs behave differently outside of the Editor and that mutating an SO creates a new instance. When no longer referenced by any persisting object, the changes made to the instance will be destroyed. A scene change will remove all changes to the SO outside of the Editor if all objects referencing the SO are destroyed.

I don't know if it's the Input System or some setting in Editor:
Is it normal that whenever I move my mouse while in playmode - I drop fps from 250 to 190 without V-Sync in the editor? I'm using Input System with action for mouse movement, but it occurs even when I disable input action map and only drops frames when I move my mouse and on keyboard input - it's all good and stable. Like, I feel it's the editor refresh causes that, but maybe I'm wrong.

#

It kinda confuses me if it's my code fault or not, lol
Just want to be sure if it's normal or not

Test in full screen playmode to see if the same issue persists . . .

short gust
slender nymph
#

use the profiler if you are unsure of where performance drops are coming from

short gust
#

It's just strange that even when it's disabled - it still drops only on mouse motion

slender nymph
#

also, a disabled component can still receive messages and react to events it has been subscribed to

#

disabling it just prevents certain unity messages from being sent to it like Update and FixedUpdate

Close and open the project and see if it goes away.

If it persists, delete the Library folder in your project folder with Unity closed to force it to refresh the packages.

This isn't the place for that discussion, I'd recommend you do your research online, but here is for Unity only

Without knowing your goal I can't advise on the 'best way' but yeah it works and so far it's good, as long as it does what you need and you are happy good, just don't forget null check if you delete something so if the game object gets deleted you null check a component, if it doesn't exist the code stops. And stop it passing 0 on the negative

Is there a way to add a field in a MonoBehavior to which you can set an arbitrary struct in the inspector?
(Like how you can make a script a public GameObject MyGameObject; and you'll be able to set an arbitrary GameObject.)

#

(I can do it with a ScriptableObject, but not any struct.)

slender nymph
#

i mean, structs don't support inheritance so the only way you can get an "arbitrary struct" is if your variable is an interface type that your desired structs implement. of course that will end up boxing the struct, you have to use SerializeReference rather than a serialized field, and you need to either draw the default drawer with your own code or use an asset like this one that draws a dropdown for you to select a relevant type from

upper totem
#

Alright. So I can't have an object field that would accept a struct. That's fine.
I just tried making my struct a class inheriting from ScriptableObject and I can't map that to a ScriptableObject field either.

slender nymph
#

if it is a class (rather than a struct) and actually does inherit from ScriptableObject then you absolutely can assign it to a field of type ScriptableObject

upper totem
slender nymph
#

you're dragging a script file, not an instance of the scriptable object

upper totem
#

That's what I thought, but I figured that's how I'd create an instance of it.

#

I'll go read some docs rather than wasting your time on basic stuff like that 😛
Thanks

slender nymph
upper totem
#

Ok, so you can have a scriptable object on a game object, but it will not show up in/be edited in the inspector?

sour fulcrum
#

not from the gameobject inspector no, because it's not specific to that gameobject

slender nymph
#

scriptable objects are assets, you modify the asset instance

upper totem
#

Ahhhhh. I'm trying to do a PoC for a way to have generic settings. I'm trying to swim in the deepend without basic understanding of Unity I guess.

winged ridge
#

You dont learn if you dont try

upper totem
#

hehe. Exactly

#

Is there a way to have a field in a MonoBehavior that will accept having any asset mapped to it?

winged ridge
sour fulcrum
winged ridge
sour fulcrum
#

Unity needs a fairly solid answer in regards to what type it is in order for it to serialize and deserialize it

#

generics are probably somewhere in the answer youll be wanting but its not that simple

upper totem
#

So I guess I could create a custom pickbox that would do that, but... humn....

slender nymph
upper totem
#

Oh, I didn't pick up on the _SerializeReference _ keyword there. I'll be reading into this, thanks.

winged ridge
#

in what way do you mean a struct doesnt support inheritance, you mean as in
public struct Test : InheritedData

upper totem
#

Yup. Can't do that in C#

#

(Just like static don't support that either.)

winged ridge
#

I know, but if you do it in a class and the class calls the struct, you can do instances of the class and call the struct each time with global variables

slender nymph
upper totem
#

(And object by transitivity)

winged ridge
# 
        foreach (GameObject saveData in objectsToSave)
        {
            state = new();
            nSaveable = saveData.GetComponent<ISaveable>();

            if (saveData == null)
            {
                continue;
            }

            if (data.sStates.Contains(state))
            {
                data.sStates.Remove(state);
                Debug.Log("Data Changed");
            }

this save system implementation I wrote, makes a new state (struct) for each Gameobject in my list, and they are all identical in everyway but data. They then get sent to a list, which is saved in a master struct if you will for Json file writing, and can be extracted based on certain key values

Skipping over this dump of code, I'll just say that you already have a moveDirection. You don't need to check both the left and right of this enemy, just in the direction of moveDirection, and if it hits something flip the moveDirection the other way. You could collapse this code to be like 1/4 the amount of lines.

polar acorn
#

Actually, you're logging a lot of info there that you didn't mention the results of. What do you log for the first two? Does it go into the if?

dense goblet
polar acorn
dense goblet
#

sorry, v tired

dense goblet
# polar acorn So what about the logs before the if

When run

we get both a Right false and a Left False.

When going into the left wall, we get a Got Into if, and a False True, we also get Left True. meaning that False True went right.

then we don't get anything else besides updates that Right false and Left False have fired off.

polar acorn
#

So, it looks like closeWallRight is just never true

dense goblet
#

I might move on and just use a tutorial for this to see if after that I'll understand whats going wrong

Remember that a circle cast won't detect anything that starts I side the circle. It has to move into it

  • each trigger object has a script where i attach:
    • destination object (where the player will teleport to)
    • the new camera bounds (to clamp the cinemachine camera to confine to the new bounds)

I tried to make an Asynchronous task that takes in a save file object, but it won't let me return it? Why?z I'm not doing anything rn just wanted to know why

grand snow
#

to return a value from an async function you need to use a generic task such as UniTask<string>

umbral hound
grand snow
#

ah well Im not psychic so we can just guess

umbral hound
#

I'm not actively working on it just wanted to know the reason in general

#

Ok

#

I'll share it when I'm back at my PC in the morning

grand snow
#

sure. Probably is what I mentioned above (the return task type is incorrect)

umbral hound
#

So basically return Task<Save file>?

grand snow
# 
public async UniTask<Sprite> LoadSprite()
{
    return await Addressables.LoadAssetAsync<Sprite>("MyCoolSprite");
}
#

you should use Awaitable (from unity) or UniTask instead of Task

umbral hound
#

Oh so I had the save file variable. All I had to do was put await in front of it?

grand snow
#

depends

byte[] bytes = await GetBytes();
return bytes;
#

anyway i gave my help and suggestions. Stop using Task

Hi, I would like to make a small weapon system for my 2d topdown shooter game and rn im wondering, what the best approach is.
On YT there are ofc tutorials but the one I found seems a bit inconvenient, however, im not experienced so i have no real clue about how to pursue.

The tutorial basically puts every weapon as prefab in the game scene as a child for the player object and deactivates every weapon except the one that should be used. for switching the weapons, the current one gets deactivated and the new one gets activated.

This seems strange for me. e.g. if i want to have 10 different weapons, i dont want to place each weapon in the scene already, or do I?
Can someone pls suggest a good variant how I could start implementing my weapon system? Keep in mind, every weapon will share the same stats (damage, BulletCount, shootDelayTime, etc.) but ofc with different value. Thats where I should use a Scribtable Object right?

Thanks in regards for any given help :)

naive pawn
#

depends on your intended system. imo the proposed system is fine if there only exists one instance of the object and it doesn't have to be moved around at all

#

using SOs instead would make it more flexible with more complexity

#

IMO - considering you've asked this in the beginner channel, i'd suggest going along with the tutorial to get something working, before making it good. (though be aware that doing that may mean that the project following the tutorial might not be viable for your final vision)

what are classes other than monobehaviour in unity namespace that a script can inherit from and be used as a component or something else

#

*commonly used classes

hardy wing
#

but there's of course much more like custom UI elements you can scratch up etc

#

and it's not like you need to know every unity class you may derive from or that it's very helpful to know all of them, you usually will figure it out on the way or when you actually need them

Yea Monobehaviour and scriptable object are the main 2 for unity specific functionality

Hi guys, how's your experience using Curves in Unity?
Ofc with SO container for obvious reasons MyCurveSO.curve.Evaluate(value)

Should the x axis always represent time? Is smoothness not guaranteed otherwise?
For example in the Curve pictured,
y axis = "allowed rotation velocity"
x axis = "difference in angle to what the player desires"
Pretty similar to how Quaternion.Slerp behaves

So, should the "current rotation max speed" approach the "desired Evaluate value" over time with Lerp or SmoothDamp?
Or is it OK that it's just straight up directly assigned every frame?

Screenshot_2025-09-21_at_12.33.37_PM.png
rocky canyon
#

for w/e reason when i expose curves like that ^ my unity freaks out

edgy sinew
#

I have a "camera distance vs. max allowed distance to move this frame" too. Which is also assigned directly every frame, no "Time.deltaTime" usage at all

rocky canyon
#

or maybe its just AnimationCurve types.. havent tried in a while maybe its fixed

but if you're misinformed the best way to find the truth is to state something else

i got confused a bit more after the replies..
i was thinking it was something like trying to change props of a material
where u need to copy out the material modify the copy and throw it bak in

#

Quiz time: why do we have to re assign material arrays when we modify it on a renderer?

rocky canyon
#

something about read-only and its a copy?

#

thats about all i got

naive pawn
#

probably because the property getter gives a fresh array

rocky canyon
#

array is copy

#

aye!

#

Chris is so elegant in his responses

grand snow
#

Yea, the array we get was just allocated for us in managed code. It is not used by unity internally.
Therefore we do have to write it back so native code land can apply our changes!

rocky canyon
#

yup.. now im just having a hard time remember other types that work similarly

#

i know theres more than just material

  internal int a, b;

      b = value[1];
    }

I think in the context of unity is that it jumps out of the CLR to whatever unity has configured to execute

all those are a bit confusing to work with

I think you can add args per project in unity hub

If support asked you to then they should have said how also

that is not setting the values of a vector3, that is setting a vector3

edgy sinew
#

I literally have 0 instances where I'm setting the .x or .y of a Vector3 directly

#

But that seems like it would be faster

#

Didn't know that was possible

hexed terrace
#

That's just because you didn't know 😄

naive pawn
hexed terrace
#

I imagine you've done transform.position.x = someFloat; it told you no, and you've assumed because it was a vector3 and you just couldn't do it with vector3's in general

naive pawn
#

probably another mov at the end too, not sure how calling conventions work in IL

#

it's... a whole thing

#

you probably don't have context to understand that yet 😅

edgy sinew
#

Assembly language class was a long time ago!

naive pawn
#

yeah but then c# is in IL bytecode so it's slightly different too

edgy sinew
#

What I do know is, you never create Quaternions in a Update loop function 😥

naive pawn
#

that's.. perfectly fine

edgy sinew
#

Doesn't it flood garbage collector

naive pawn
#

but you shouldn't do new Quaternion in general unless you're a math major

naive pawn
hardy wing
#

Why does this not work? According to docs the "clickable" needs a collider and I have attached a Circle Collider 2D and it still doesn't log.

public class Point : MonoBehaviour
{
    void OnMouseDown(){
        Debug.Log("Sprite Clicked");
    }
}
naive pawn
hardy wing
naive pawn
#

if you're on >=6.1, it's set to the new system by default
OnMouseDown is not sent with the new input system

edgy sinew
# naive pawn no, Quaternion is a struct too

So you're telling me... These two will give the same FPS performance?

Quaternion q2;

void myUpdateLoop() {
    q1 = ...;
    q2 = ...;
    // code
}

void myUpdateLoop2() {
    Quaternion qTemp1 = ...;
    Quaternion qTemp2 = ...;
    // code
}```
hardy wing
#

And how do I get the functionality with the new?

naive pawn
#

but also, this is so minor that it won't have any practical impact

edgy sinew
naive pawn
#

no, that's equally not an issue

edgy sinew
#

Wait but, no that's a

#

... atwhatcost

naive pawn
#

Vector3 is also a struct. it is not garbage collected

edgy sinew
#

Quaternion is an... Object

#

So that's why it gets GC'd

#

But Vector3 is a struct so it's never GC'd

slender nymph
#

quaternion is a struct

naive pawn
#

being an object doesn't affect whether or not they're GC'd

edgy sinew
#

But, doing new Quaternion(...) adds lag, but new Vector3 doesn't?

#

oh

naive pawn
#

neither of them are GC'd

slender nymph
grand snow

c# is weird that you use new even with structs

edgy sinew

if not would you recommend any resources (i already know git-amend and Jason Weimann)

naive pawn
#

this:

Vector3 x = new Vector3(0, 0, 0);
```is less work than this:```cs
void Update() {
  Vector3 x = new Vector3(0, 0, 0);
}

this:

void Update() {
  new Vector3(0, 0, 0); // value type
}
```is less work than this:```cs
void Update() {
  new System.Object(); // ref type
}
grand snow
#

yay stack allocation

hardy wing
naive pawn
#

this:

Vector3 x;
void Update() {
  x = new Vector3(0, 0, 0);
}
```is equivalent (in terms of work done) to this:```cs
void Update() {
  Vector3 x = new Vector3(0, 0, 0);

Hi guys, what is your recommendation to get a smooth stable 60 FPS?

I've tried Application.targetFrameRate = -1; but, as I understand, that literally maxes out your computer, in other words trying to render as many frames as possible. Exhausting especially since my machine will go to like 550 FPS

But, Application.targetFrameRate = 60; gives sooo many dropped frames
🤷‍♂️

#

Am i just having a Unity 6.2 issue? Should I be on 6.0? Or is this common when playing in Editor?

grand snow
#

I read something about this very recently and it seems this is impemented very badly on desktop

#

so do not use it

edgy sinew
#

What do you mean? the targetFrameRate thing?

grand snow
#

yea this

edgy sinew
#

Do you mean for Unity 6.2? or does this apply for 6.0 / previous too

edgy sinew
# grand snow yea this

If you can send the resource I'd love to check it out. It's driving me crazy I want my 60fps 🤣

hardy wing
grand snow
#

im trying to find what I read but I cannot anymore 🙁

naive pawn
#

check docs, i guess

edgy sinew
#

Desktop and Web: It is recommended to use QualitySettings.vSyncCount over Application.targetFrameRate because vSyncCount implements a hardware-based synchronization mechanism, whereas targetFrameRate, which is a software-based timing method is subject to microstuttering.

grand snow
# edgy sinew Wow... So no wonder my project says 500 FPS but still stutters

https://fixupx.com/__silent_/status/1968258166778671459

Silent (@__silent_)

This isn't just placebo, it affects Unity games all over - the moment they use this in-built frame limiter, they are at a mercy of the Windows timer resolution (1ms) and they stutter. Special K increases the resolution to 0.5ms so it performs better, but still far from ideal.

Quoting Silent (@_silent)
︀
Sounds like @unitygames themselves discourage from using the built-in frame limiter? Could this be the cause of many Unity games dropping a frsnet every few seconds when limiting to 60 FPS? docs.unity3d.com/6000.2/Documentation/ScriptReference/Application-targetFrameRate.html

Okay I'm about to try the "hardware-based synchronization" let's see.

edgy sinew
slender nymph
#

targetFrameRate is a static setting, not tied to a specific scene so naturally the setting will persist

edgy sinew
#

Got it.

naive pawn
#

it's set on Application, not the scene 😉

edgy sinew
#

But, it says when you do QualitySettings.vSyncCount = 1;

#

That you should not have a target frame rate

#

So... Am I supposed to see 550 FPS or 60 FPS

they'd probably fight each other, i'd guess

I thought, if you set vSyncCount to non-zero, the targetFrameRate has no effect

So much for that

if i beginner and i want to make very good 2d game, which one should i use?

doesn't matter, tbh

thanks

naive pawn

they can both get the job done

edgy sinew

yeah

but do realize that - as a beginner - you just won't have the skill/experience to make a good game at first, no matter what engine you pick

it'll take time and practice

edgy sinew

that's the important part, you, not the engine

Unity is a little more "do the thing this way or that way, but those are the only 2 good ways"

ok

Or, for achieving good framerate on desktop, I guess downgrade to Unity 2021 or something!

Drag 2D objects in Unity - using the mouse to move sprites.

Nearly all 2D games require you to click or touch to drag objects around the scene. E.g., in a jigsaw game. This tutorial shows two methods for doing this within Unity.

The first method is a script which you can attach to any object you wish to move. This utilises the OnMouseDown and OnMouseUp methods.

The second is to create a central manage...

ik the game jams need to be made then but I want to make a similar game type so I wont be a total noob, the game jam is in 18 days

#

I tried to look for a movement tutorial but I cant find anything good

edgy sinew
# raw shore I want to prepare for a game jam the horror one on itch, the idea is simple you ...

Sure gotcha. There are different ways to do Character Movement here's a few common.

  1. Character Controller component (easiest I think, most control, least headache)
  2. Rigidbody kinematic (not super difficult, has natural interaction with Physics objects.)
  3. Rigidbody dynamic (to maintain interpolation you can only use AddForce and Torque. Say goodbye to assigning velocity in a chill way, we're doing PID controllers & calculus now)
#

Unless you are going to like, jump through a stack of cardboard boxes in the game, option 1 is the easiest

raw shore
#

I am a total noob so what should be good

#

and I need you to be able to be shot

edgy sinew
#

#1 unless you need natural Physics interactions (NVidia PhysX is what Unity runs on)

#

I'll send some videos that are good. Remember, always doubt the tutorial

raw shore
#

I mean you will need to press e to take the pizza (goal)

edgy sinew

Yeah that's not hard, that's like proximity detection and then keydown events.

raw shore

and the forest is not plane

edgy sinew

like a high res terrain right

You got terrain stamps and all that ready?

raw shore

nope :))

edgy sinew

Unity gives some free trees and foliage, in their demo projects

and get Terrain Tools package too, it has other stuff in there

google has plenty of actual, trustworthy, primary resources you can reference instead

90% of times it takes the code from reddit or stackoverflow 🤷‍♂️

Sure... If the AI is right, I'll just copy paste the text then lol

so the characther controll it is ?

please don't

edgy sinew

Okay so I'll re-write what the AI said, if it was correct, in my own words

naive pawn

you are a beginner, and you do not have the experience necessary to confirm that it's right

just don't reference AI at all

edgy sinew

When you're not here, I can help the people who are even more beginner than me

raw shore

yeah ik AI is trash

naive pawn
#

use the actual primary resources

naive pawn
#

just use google

edgy sinew
#

.... Brother I have like 500+ bookmarks on this shit

naive pawn
#

it's easier to go to the trustworthy resources than to go through AI and then check it again

raw shore
#

can someone give me a good tutorial for charachter controll ?

edgy sinew
naive pawn
#

going through AI actively harms yourself and the people you're trying to help, and just wastes time in general

edgy sinew
#

... Alright, cool. I'm just saying 90% of what you Google, the AI will scrape correctly the needed info

#

I got pics to prove it but I'm not interested in this topic

naive pawn
#

so why not just go to the original source and get 100% accuracy

#

buddy this has been debated since genAI became popular

edgy sinew

Because when you click on the "original source" it's word for word what the post had?

the consensus is not changing

Great thanks

don't risk that 10% on the people you're trying to help

Kinda why I said, I read the text first before sending

But yo, go off

no-one is saying genAI is wrong. the issue is that it frequently isn't right

#

I really do have like 500 bookmarks of Unity stuff

Start now trust me. Keep everything organized, keep the knowledge by category

raw shore

how do I make a bookmark

edgy sinew

like in Firefox or Chrome?

raw shore
#

I have the app

naive pawn

@hardy wing do you still have issues? make sure you've added an appropriate physicsraycaster/physics2draycaster and the eventsystem is set to the new input system version

edgy sinew
raw shore
#

oh he said folder so I guess notepad

edgy sinew
#

I mean in your web browser, like Firefox or Chrome

naive pawn
#

browser bookmarks support folders too

edgy sinew
#

I mean keep a .txt file of bookmarks if u want

raw shore
#

I meant to these texts in discord

edgy sinew
#

Click link, that opens in your web browser, right? Then bookmark it?

raw shore
#

or go to a friend that has the acc deleted and send there

edgy sinew

What

naive pawn

or just make your own server

edgy sinew

you likely are doing something different. they are not responding to input from an input action asset, they are responding to pointer events which the event system handles

does anyone know why the skeleton isnt running towards the player when it detects it

#

its not even attacking

whys it raiding the console

#

It's raiding the console because it's a debug.log in the Update method which runs every frame

hidden fossil
#

dude whys it not speeeding up

I cannot see all the code in the Enemy : Entity script, but it seems to be an issue with either logic or the state machine

hidden fossil
#

oh ill show it to u

#

!code

radiant voidBOT

winged ridge
#

so for attacking, this line should put the enemy into its relevant state
stateMachine.ChangeState(enemy.attackState);
However only if
WithinAttackRange()
throws true, just out of curiousity, can you change WithinAttackRange() to check for a false ie

        if (!WithinAttackRange())
        {
            Debug.Log("attacking player");
            stateMachine.ChangeState(enemy.attackState);
        }
hidden fossil
#

oh ok

winged ridge
#

if it works, it was your logic in the WithinAttackRange method that is flawed, if not then its the stateMachine.ChangeState that is flawed

hidden fossil
winged ridge

Did it run the attack animation you wanted?

hidden fossil
#

wait

#

lemme try again

#

i removed the deubg line

#

no its not

#

it still just walking

winged ridge
#

so it wont enter into its attack state, which means there is a logic issue within the State Machine and its enemy.attackState

well the way state machines tend to work is this: They have an idle state - this usually has limited actions other than perhaps some calculations and animations,
If the opponent is within range and conditions are completed it enters a new state which in your case is attack state
If the conditions are not complete or the opponent is not within range, it may go to another state
Each state has its own set of logic and conditions, you have a controller that picks which rules it needs when it needs them
