i could

#

but its mainly for like player position in singleplayer like they can just teleport easily

echo ruin
#

But it also means that the save will get lost if your PC breaks down. And it’s also easy to manipulate a save file, encrypted or not

wintry quarry
#

There's a difference between actual storage and a cache. What you're describing is a local cache, not the canonical storage.

#

The source of truth of the data would still live in the cloud

drifting cosmos
#

i dont really want to run servers for single player

#

is there any difference in how easy it is to change things like player position in say a single player game mode

wintry quarry
#

Huh?

echo ruin
#

Depends on the game

wintry quarry
#

This conversation is way too vague and lacking in context to provide any kind of sensible answer to that question

drifting cosmos
#

without server side validation you maybe could change your position like say youre at one side of the map you can just say youre at the other side

wintry quarry
echo ruin
#

Is that the multiplayer or singleplayer part?

wintry quarry
drifting cosmos
#

singleplayer

wintry quarry
#

If it's single player there's no server

#

so the question makes no sense

drifting cosmos
#

well like if you edit your position and send it to the game

#

wdym it makes no sense

wintry quarry
#

Because then you're not talking about single player

echo ruin
#

Why shouldn’t you be allowes to manipulate position in single player?

drifting cosmos
#

its connected to an online game

wintry quarry
#

So it's an online game

drifting cosmos
#

single player mode

wintry quarry
#

Maybe you're confused about the difference between realtime and non realtime multiplayer

drifting cosmos
#

say you have coins if you could just get 1000000 coins in singleplayer it would ruin the multiplayer part

wintry quarry
#

but either way what you're describing is decidedly not a single player game

echo ruin
#

Are you playing on a server or is someone hosting the multiplayer game?

wintry quarry
#

If your actions are visible to or affect other players, it's a multiplayer game

drifting cosmos
wintry quarry
#

If we're talking about a non realitime game where you do a bunch of stuff locally and then send the result to the server, yes the server should be validating the thing you sent.

drifting cosmos
#

yeah its not verifying every second though

wintry quarry
#

that's not an issue

#

it needs to be verified when it makes sense to verify and when it matters to verify

#

Think about chess

#

we don't need to verify chess every frame

#

only when a player makes a move

drifting cosmos
#

yes but movement happens a lot

wintry quarry
#

what is "a lot"

drifting cosmos
#

like if you have a free moving character

#

and not like a turned based thing

wintry quarry
#

Sounds like a realtime multiplayer game

drifting cosmos
#

then it would also be cheaper to run a server anyway

#

but no other people in the gamemode

#

i dont want it easy for people to just teleport around the map

#

even if im not verifying each position

wintry quarry
#

You don't need to verify each position

#

you only need to verify the positon when the game is "synced"

#

as you say

drifting cosmos
#

well like if you have 3 minutes to say run around

#

i mean there would be nothing to verify

wintry quarry
#

Sure there would be

#

Let's say you move at 1 meter per minute

#

if the player ran for 3 minutes then the server can verify you haven't travelled more than 3 meters

drifting cosmos
#

but they could just send in

#

that they traveled for less than 3 meters

wintry quarry
#

Indeed

#

There's nothing you can do to stop that

#

Unless there are other restrictions to enforce

drifting cosmos
#

well i was hoping that encrypting it and like changing it up or something would make it so that if someone does break the encryption i can just change it so they cant do it anymore

#

and repeat that process

charred spoke
#

I still don’t get the “connection” between the singleplayer party and the multiplayer. How exactly does teleporting in singleplayer affect other users ?

ivory bobcat
wintry quarry
drifting cosmos
ivory bobcat
#

And the server could say, no.

drifting cosmos
ivory bobcat
#

Invalid position. You're moving too fast. Disconnecting player.

#

So you collect coins in singleplayer that then have an effect on multiplayer? Then your game is not singleplayer at all

drifting cosmos
drifting cosmos
charred spoke
#

It’s multiplayer where you have a lobby type game mode with just 1 player

charred spoke
ivory bobcat
#

If it is associated with multiplayer at any point, it's practically multiplayer

drifting cosmos
drifting cosmos
ivory bobcat
#

Offline modes usually do not reflect upon online competitive modes

charred spoke
#

Then your game is not singleplayer

drifting cosmos
charred spoke
#

But..you kinda are

drifting cosmos
#

like story mode in gta is singleplayer but it also has an online mode

#

it is multiplayer it just has a singleplayer mode

#

guys why does it matter anyway

ivory bobcat
#

Security in an offline game is tedious and near impossible.

charred spoke
#

Yes and when I potentially cheat in story mode nothing carries over to the online part

ivory bobcat
#

Online can be regulated on the server side

drifting cosmos
charred spoke
#

If a game carries things over from singleplayer to multiplayer then it is not a true singleplayer game

#

It’s just multiplayer

drifting cosmos
#

its not a singleplayer game

charred spoke
#

1 connected player is still multiplayer

drifting cosmos
#

singleplayer GAMEMODE

#

i got my answer anyway

echo ruin
#

People don’t need to know how to decrypt to manipulate the game in this case. Someone will write and post a script, and it will be as easy as 9 year old kids googling “minecraft cheats”

drifting cosmos
#

unless someone tells me different about encryption

echo ruin
#

But to be fair. You can still experiment with encryption. It doesn’t hurt to learn a bit

drifting cosmos
#

i know games using it for

#

save

#

and no verification so i just thought

echo ruin
#

I think at most it will disencourage a few when they google how to change save file data, and that they have to download a script rather than just manipulate a json or XML file

#

But you can do it 😄

Hey, quick question. I want to have a button in my game be attached to an image, but when it’s clicked on, I don’t want to destroy the image, just destroy the capability to use the image as a button again. Is that a possibility? If so, how would you go about it?

It’s useful in terms that it does what it says in the docs

buoyant finch
charred spoke
#

I.e when I want to change some configuration

celest ore
#

but why would u want to change it

#

like i push my unity project on github, i never used it

#

why would someone need it

#

thats my question

charred spoke
#

Push with a different user name among a variety of other reasons

celest ore
#

because i never used it in my lifetime

charred spoke
#

Nothing is compulsory what are talking about

#

Git is a set of commands

#

You use the command that does the thing that you want

#

I personally use a global config for all my work projects, which specified my real name and work email.
All my personal projects use a local git config that uses my "programmer name" and personal email.
if you dont see the point of the config, you probably dont need to change it.

Anyone got a good tutorial on how to make 2d top-down movement feel smooth and exactly how you want it?
I got this nice simple code:

{
    moveInput = new Vector2(Input.GetAxis("Horizontal"), Input.GetAxis("Vertical")).normalized;
}
private void FixedUpdate()
{
    rb.velocity = moveInput * moveSpeed;
}```
But it doesn't allow me to adjust much, like how fast the player starts & stops, or do I just use the rigidbody for that? Not sure what the proper way is to optimize this.
#

also should I be using GetAxis or GetAxisRaw?

astral falcon
# topaz mortar also should I be using GetAxis or GetAxisRaw?

I suggest getting familiar with the new input system instead. And about "how you want it". Well, how do you want it? Its all just about using known concepts to smooth, slow down and what not. There are courses and pathways on Unity learn too, to get into 2D dev

topaz mortar
astral falcon
wintry quarry
#

Honestly it's too vague of a question.

In order to get movement "precisely how you want it" the first step is being able to precisely describe the movement in English.

The concepts are simply understanding the update loop and the general principles of the physics engine and math.

#

you can always skip what you already know and take what you need from it

#

not sure tho, if it uses 2d physics for the player or position movement.

topaz mortar
#

all the tutorials I've found just have the speed variable, they don't even mention the rigidbody (other than adding it)

wintry quarry
#

There's no right or wrong way to do it

topaz mortar
#

by mass I mean linear drag

wintry quarry
#

The answer is it depends on your requirements

#

The point of tutorials is to familiarize you with the concepts not to create an end product

topaz mortar
#

so are there other ways (with the physics system) to adjust player movement? other than setting the speed velocity / mass / drag?

#

or is that it?

wintry quarry
#

Using forces,
Directly modifying the velocity
Using kinematic approaches with your own simulated momentum

#

The possibilities are essentially endless

warm field
#

did they update the unity programmer pathway recently?

wintry quarry
#

The built in drag is only one very simplified drag implementation.

topaz mortar
#

not looking for anything too crazy
so basically I just adjust the speed (velocity) and mass & drag until I feel satisfied with how my movement feels?

warm field
#

because i see use unity 6 now

wintry quarry
#

As were discussing the many ways to do precisely that

topaz mortar
# 
{
    rb.velocity = moveInput * moveSpeed;
}```
moveSpeed basically
wintry quarry
#

That is one possible approach

#

You are setting the velocity directly

#

And mentioned there are many ways to do it, and none are "best", they're all just different and may satisfy different needs

topaz mortar
#

so where/how can I find a tutorial that explains it a bit?
all the tutorials I find are just "1 min 2d top down movement" and just show the code I have

wintry quarry
#

There's a major issue with that approach - it completely negates the ability for external forces or any of your other code to affect the object's motion.

Depending on your game requirements that may or may not be a problem

YouTube tutorials tend to be more for entertainment value and tend towards the "quick and easy" approach rather than actually teaching you concepts

topaz mortar
#

what's a better platform? learn.unity?

#

I looked at the tutorial linked above but it doesn't use physics

there should be the unity essentials or junior programmer pathway

I've been around for a while 🙂 just haven't made a game like this before

Not necessarily because it's a bad thing, but you likely get less of an answer here since people that check this channel generally know more of coding.

visual linden
#

How come it isn't already 1x1 by default? Is there some aspect ratio thing being enforced?

chrome apex
#

cause transform distance is in meters

crystal chasm
#

Ok. It's easy to scale in code

visual linden
#

You could get the scale of the sprite in screen space, and then scale it by the screen space mouse coordinates. That way you don't have to worry about the world space scale.

#

I feel like a noob asking this how can I remove this? square outline
I did confirmed it's from the UI. it's not there before. how do I turn off?
help please ^^

crystal chasm
#

You'll need to reference the two different world space positions with vector3s from the mouse clicks, and measure that distance using vector3.distance, then just set the scale of the quad using transform.localscale = new Vector3(distance,distance,dustance);

burnt vapor
#

Next time please use the proper channel, this is a coding channel

blissful yarrow
chrome apex
#

if it's huge, the scaling won't help

crystal chasm
#

Distance * 0.5f

#

If they are 2 meters

chrome apex
#

yea but I don't know how to make them 2 meters in the first place

#

if I did, I'd make them 1 meter

crystal chasm
#

Do you have unity open?

chrome apex
#

yes

crystal chasm
#

Drag a cube into the scene

chrome apex
#

ok

crystal chasm
#

That's 1 meter

chrome apex
#

man I'm using sprites, that's different

#

2d

crystal chasm
#

You can't have a cube in 2D?

#

We are just scaling here

#

The cube will be deleted

chrome apex
#

I mean I can

#

but I won't be able to match it exactly

#

just by ''eye''

crystal chasm
#

Idk what you mean.

#

You can't scale the quad to be the same size as the cube by eye?

chrome apex
#

I can

#

but I'd prefer to make it exact

crystal chasm
#

Anyway. I wish you luck

chrome apex
#

thanks

chrome apex
crystal chasm
#

Thats good

#

So you can just set the scale to the distance between the mouse clicks.

Hey guys, ive done a lot of reading/googling on this and I think its probably my knowledge of how it works that might be the problem but I am trying to get my camera to use the scroll mouse to move in and out of zoom which seems pretty standard. The code I am using is:

void Update()
{
    CameraMove();
    RotateCamera();
    Zoom();
}

private void Zoom()
{
targetFOV += Input.mouseScrollDelta.y * zoomSensitivity;
targetFOV = Mathf.Clamp(targetFOV, minFOV,maxFOV);
virtualCamera.m_Lens.FieldOfView = targetFOV;

But when I go to test the scroll does not work at all? I know the camera script is working to some degree as I have set movement and rotation which both work but its purely the mouse scroll side that doesnt.

I have checked the input settings in Unity and I believe they are correct

frosty hound
#

First thing would verify you have values set for sensitivity and the min/max values you're using to clamp.

ornate patio
frosty hound
#

Because these are serialized, the value in the inspector is the one that's used. Double check those are not changed

ornate patio
#

Unfortunately don't think its that unless im missing something

image.png
frosty hound
#

Okay, drop a debug log into the function and print out the FOV value

mint bluff
#

I don't get it. I am using the Tilemap.HasTile() to check if there is a tile at the location. it gives true when there is a neighbour to the upper right to it. why is that?

#

so this will return true for that empty tile

#

this will return false

almost. it's right in the cent erof that empty tile

#

Is your tilemap scaled so that every tile is 1 unit?

#

Hmm actually don't think that's relevant here

mint bluff
#

does that help?

# mint bluff does that help?

Add this to your monobehaviour:cs void OnDrawGizmos() { Gizmos.color = Color.magenta; Gizmos.DrawSphere(tileMap.CellToWorld(new Vector3Int(1, -4, 0)), 0.5f); }

#

(You know that HasTile takes cell coordinates, not world coordinates right?)

mint bluff
#

No I don't

#

and that makes sense now

#

I am 2D rookie and I'll have to read up on cell coordinates. THANK YOU @verbal dome

ornate patio
frosty hound
#

Yep. I know Cinemachine 3.0 changed a bit of how things were modified since it simplified it. I haven't used it yet so I don't know if that's actually how you change the FOV property.

#

Beyond that, the only thing I can think of is it's targetting the wrong virtual camera or you're overriding the FOV elsewhere.

this is the method for it

Verify that that function is actually running. Put a Debug.Log in there.

ivory bobcat
#

Log the value of the player before teleporting, after teleporting and the check point location?

If you're using the Character Controller component, you'll not be able to teleport with Transform without first disabling the component

Can a scriptable object extend a normal script?

#

or inerhit is probably the correct word

verbal dome
#

Nope

fickle stump
#

well f me then

verbal dome
#

You can store a custom class inside it though

fickle stump
#

the idea i had is to instead of writing a differnt script with essentially the same content but different references, i'd create one scriptable object that one script can inherit

#

if that makes sense

verbal dome
#

You can make a base class for your scriptable object, yeah

#

For example... cs public abstract class BaseSO : ScriptableObject {} public class ChildSO : BaseSO {}

fickle stump
#

I'm making an simulation where the user has to find various issues around the workplace such as different objects laying around or spilled oil. And instead of hardcoding them i'd love to have some kind of "list" that i can easily extend with other issues that are very similiar in funciton

fickle stump
verbal dome
#

If you want a SO, you need to inherit from SO

#

I don't think I get your question

#

You can add any shared functionality to the BaseSO class

#

And every instance of ChildSO will have that functionality too

fickle stump
#

hold up

#

i might be stupid

#

oh

#

yeah i am fucking stupid

What's the best variable type for a date, to store in a database of different entries in a compendium with a "release date" for each?

rich adder
#

or make your own struct

tulip stag
#

Thank you!

#

Also; sorry, there's something I read a bunch of times and I still don't understand. I need someone to explain it like I'm stupid.

#

What's with the {get; set;} I see some people do after some variables?

rich adder
polar acorn
tulip stag
#

Oh ok. And when do I know that a variable should be a property and not a variable?

#

I think all of these are properties, no? Intuitively?

image.png
rich adder
#

for example you want a variable to be accessed by ANY script so public but only set private through its own script

polar acorn
tulip stag
#

Oh đŸ˜”â€đŸ’«

rich adder
#

also property lets you run some logic if you also, when the variable is changed or Read

polar acorn
#

In general, properties are seen as better, because you could add functionality later. If you want code to run whenever a variable is changed for example. Another benefit is for debugging, you can put a break point on a get and see what is trying to read from a variable

#

If it's private, a variable is probably fine

#

If it's public, you should probably be using a property instead

rich adder
#

always go for a Public read while private Set. thats the major benefit

naive pawn

# 
    public int MyDigit  = 66; //can be read/changed from any script
    public int MySaferDigit  {get; private  set;} = 77 //can be read by any script, can only be changed in this script```

Thanks!

#

properties are just methods disguised as fields

polar acorn
#

Like saying "Red Big Ball" instead of "Big Red Ball"

rich adder

idk why i wrote it that way first time...dyslexia peaking maybe..

-# footnote: some languages don't have separate fields/properties, and may treat them as synonyms. some languages call their equivalent to properties, "accessors", while "property" is a synonym for fields.

polar acorn
naive pawn
polar acorn
#

So, if you have a String you want changed by a UIInput, it would need to be a property

rich adder
#

Some APIs & framework also don't like working with fields so they use props (MVVM on MAUI only liked props for databinding, idk if its changed)

#

Interfaces also use Props not fields

hot laurel
#

well they are just set and get method with backing field, no magic there, if api works with properties its because it needs a method

image.png image.png
#

so using empty properties is misleading

short hazel
#

Using properties is the recommended way of exposing data everywhere

naive pawn
#

how are they "misleading", exactly?

short hazel
#

If one day you need to add stuff that runs on get/set, you only modify one place in the code

hot laurel
#

since it does nothing to the backing field but it looks like method - it is method

short hazel
#

It's a matter of consistency

polar acorn
short hazel
#

Either use props everywhere or nowhere

naive pawn

#

There are a few benefits to using anonymous auto-properties in place of public variables, but "few" is still more than "none" so it's better to do so than not

naive pawn

Java's style guides basically forbid public variables, and insist all variables actually be private with two manually created getter/setter methods

hot laurel

and i didnt meant other languages

naive pawn
#

we aren't mind-readers, just say what you mean lmao

#

if i say "property without set", would you assume that there is a set, just without a body?

#

i still don't see how that's misleading though

Hello guys! I have started learning Unity yesterday, following some youtube tutorials.. So I was following this video on how to implement the new input system, but it's happening something strange and different from the video..
As you can see from the picture, I added the Player Input component, then linked the actions (which for now it's just up / down / left / right), and then linked the Movement Script.. this is the script:

public class Movement : MonoBehaviour
{
    Rigidbody rb;
    public float moveSpeed = 0f;
    Vector3 direction = Vector3.zero;

    private void Start()
    {
        rb = GetComponent<Rigidbody>();    
    }

    private void Update()
    {
        rb.AddForce(direction * moveSpeed * Time.deltaTime, ForceMode.Force);
    }

    public void MoveEvent(InputAction.CallbackContext context)
    {
        if(context.performed)
        {
            Vector2 input = context.ReadValue<Vector2>();

            //direction = new Vector3(input.x, 0, input.y);
            direction.x = input.x;
            direction.z = input.y;
        }
        // Stopped performing context
        else
        {
            direction = Vector3.zero;
        }
    }
}

At this point, in the Events -> PlayerMovement dropdown, I was expecting to find the MoveEvent method from the script, but there is no way to make it appear.. any idea on why? the youtube video I was following, it just appeared there the method created inside the script

You need to drag in an object with the script on it, not the text file containing the code

proud escarp
#

So I can create an empty object, assign it there, and then assign the script to that empty object?

naive pawn
#

have you added the Movement component to your player object?

naive pawn
polar acorn
proud escarp
#

I tried to assign the script to the Player Object

image.png
naive pawn
#

have you saved and compiled all of your scripts

polar acorn
proud escarp
#

So, followinf the video those were the steps:

  1. Create Actions and assign them (for example) at the keyboard
  2. Attach to the player object the Player Input component
  3. Attach the actions created to that Player Input component
  4. Create a Movement script with the method
  5. Go to events, player movement, attach the script there and use the functions (using Invoke Unity Events)

You cannot drag in a script file into the event. You have to drag in an object that has that component

#

the text file isn't going to be running any code

#

The Movement.cs file is not a Movement object. It's a text asset

Hello, messing with editor scripts and noticed I can't cast target to the class I'm working with. Is there something else you gotta do?

It'd be a PropertyDrawer, not an Editor

gloomy cosmos
#

a ok, thanks a lot 👍

polar acorn
#

I have only approximate knowledge of editor scripting

polar acorn
#

But I'm pretty sure int natively downcasts into float

naive pawn
#

not when you have int/int

polar acorn
#

So if you did float x = someIntValue it'd just workâ„ąïž

frigid sequoia
#

But adding the float is not like... gonna turn it into a float AFTER the calculation, therefore having basically no effect?

polar acorn
naive pawn
polar acorn
#

and then it'll do proper float division

#

I misunderstood the question

naive pawn
frigid sequoia
#

So this???

image.png
naive pawn
#

int/int does integer division, same with any 2 integral types
if either operand is floating-point, it does float division

naive pawn
polar acorn
naive pawn
#

it will cast a to float first, then it will do the division

polar acorn
#

since that's another int division

#

But I'd recommend storing those in variables, that if line is getting a bit chonky

naive pawn
frigid sequoia
#

Works wonders, thank you

frigid sequoia
#

Huh, can I not... adjust the target frame rate directly from the editor? Does it need to be by a script?

wintry quarry
#

Yes, needs a script

How inconvenient....

So i exited unity the other day with code that wasn't really finished and it gave me a warning before exiting that I didnt read. Now when im coding in visual studio it wont tell me if there are errors in the code, I have to save the code to see if any errors come up in unity. Any way to turn back on whatever I turned off?

You may just need to regenerate the project files from the External Tools menu

assuming that everything was set up properly beforehand

kind of weird that it'd break in the first place

Hello, I have a bit of a problem while working in PropertyDrawer.
I wanna show a variable in the inspector, so I do:

EditorGUI.PropertyField(valueRect, serializedProperty);

It works when serializedProperty is an int, float, array, etc, but if it's a custom class or struct (even if Serializable) it just draws a dropdown which when opened shows nothing. What could be wrong?

slender nymph
quartz anvil
#

So My IDE is configured correctly and the Right IDE is selected in the external tools menu, I think its setting in Visual studio itself to stop underlining errors in code

#

its a setting*

wintry quarry
quartz anvil
#

I hit the "Regenerate project files" button and nothing happened. When I save my code the errors pop up in the unity error list but not in visual studio

#

LMAO nvm, figured it out

#

had build + intellisense instead of just build selected.

#

actually I spoke too soon, I can see some errors but code isnt highlighting right anymore either 😩

slender nymph
#

restart visual studio, and if the issue persists check the solution explorer to make sure your project is actually loaded. if it is unloaded or incompatible then right click it and reload with dependencies

# naive pawn lerp already doesn't slow down at the end

it will when u pass in the variable ur manipulating into the lerp itself..
transform.position = lerp(transform.position, target.position, .5);
sorta like the inchworm on a rubberband puzzle..

like if u were to use .5, goes half to target.. then half of that to target.. then half of that to target.. incrementally getting smaller and smaller and smaller..

thats why the wrong lerp info is always sent first..
thats usually the problem lol

naive pawn
rocky canyon
#

as intended.. no u and digi are correct..

#

i like Movetowards as an alternative.

#

b/c if i thinkin correctly. i always use an extra variable to do a proper lerp

naive pawn
#

MoveTowards is just lerp with SmoothDamp parameters/SmoothDamp but linear, right?

rocky canyon
#

^ i believe so..

swift crag
#

I wouldn't say any of that is true :p

#

It is in the same ballpark as lerp, I suppose

#

Instead of a percentage, you give it a maximum delta

#

It moves from A to B by at most C

#

lerp moves from A to B by C%

rocky canyon
# 

(by the way, using ‘time’, e.g. Time.deltaTime as the parameter is a common mistake when using Lerp. It can be done to get a nice “easing out” effect, but you have to understand that if you never call Lerp with the last parameter as ‘1’ ( meaning 100% ), the position will never get to the ‘end’ value )

The last parameter in MoveTowards is the max distance to move: "give me a point that is at most ‘time’ units closer to ‘end’, starting from ‘start’ "``` seen this on a discussion page

Honestly, I wish their implementation could safeguard against the smoothing error everyone commits . . .

It's a very simple mathematical function

(but not exactly, because SmoothDamp never reaches the target)

#

oh yeah, there is that extra "max speed" parameter

#

I often use a combination of SmoothDamp and MoveTowards when I need to actually reach the destination

polar acorn
swift crag
#

I use exact float equality with MoveTowards, to the horror of Rider

rocky canyon
#

can't DoTween be used for all of these easing type functions?

#

as an alternative

#

pretty sure i have a friend that uses DoTween for everything he possibly can..

MoveTowards is the only one you really need. At least you know it reaches the target . . .

rocky canyon
#

i have a project w/ nothing in it but DoTween.. and im pretty sure something ive done has broken it.. as it has frequent frame drops.. or stutters rather

#

most likely user-error.. but i've had friends give me alternatives.. (on github) of ones that supposedly are more optimized with less GC

hey 🙂 im pretty new to unity but i wanted to ask cause i cant find anything online...

how would you go about making a WASD movement as a global x/z but have the character always facing the mouse? like how Path of Exile 2 does it? 🙂

cosmic dagger
# rocky canyon ah, so ur not actively using it atm?

I made it a long time ago, but I want to update it. I've done a few improvements, like adding a state machine for the Timer; delegates for each timer phase: cancelled, completed, suspended, resumed, updated, restarted; binding it to a MonoBehaviour, and created Set methods to avoid creating a new instance. I'm going to add object pooling this week and try to store the timer information in a struct to save/help with gc . . .

rocky canyon
wintry quarry
#

for rotation - like Spawn said, use Camera.ScreenPointToRay and Plane.Raycast to get a world space position for the mouse and then just have the player look at that position.

okay cool! thats probably enough to do some googling around and try to tinker with

#

Hi! I was just wondering how many frames people usually get in their editors. I am getting around 300 frames and I was wondering if this is too low for the editor. Are the editor frames going to be much lower than the build frames as the editor is keeping track of many more things?

Why do you think 300 frame is low

young lava

I was getting like around 700 frames before adding in a bunch of features involving networking and pretty much I was wondering if it was an optimization issue or just normal

please note that is only a difference of 2ms per frame

I am having trouble adding CanvasScaler components to a visual studio library project. I've added a reference to UnityEngine.dll, which has been a great help, but upon trying to include UnityEngine.UI.dll for CanvasScaler, I get an error about there not being an implicit conversion from CanvasScaler to Component. The exact text is as follows: The type 'UnityEngine.UI.CanvasScaler' cannot be used as type parameter 'T' in the generic type or method 'GameObject.AddComponent<T>()'. There is no implicit reference conversion from 'UnityEnginer.UI.CanvasScaler' to 'UnityEngine.Component'.

In case it is related there is another error stating: The type 'MonoBehaviour' is defined in an assembly that is not referenced. You must add a reference to assembly 'UnityEngine.CoreModule'. When I add CoreModule, I get a ton of errors due to conflicts between UnityEngine and UnityEnginer.CoreModule. Any help would be appreciated!

cerulean dove
#

As far as I understand it, CanvasScaler inherits from UIBehaviour, which inherits from MonoBehaviour, which should have component in its ancestry.

Hi guys does anyone know how I can make my layer work exactly like the** ignore raycast** layer, I have a large project and I am not going to be able to change the layer mask in each and every raycast.

image.png
cerulean dove
wintry quarry
#

Raycast simply has a default layer mask that ignores it

timber tide
#

Yeah it's just placeholder I throw everything on that I want to filter out

#

UI is actually a pretty wierd default layer now that I think about it cause most raycasts cant even interact with it

frigid shadow
wintry quarry
#

the layer doesn't do anything

#

the mask is what excludes it

polar acorn
#

That's all

wintry quarry
#

Indeed:

The default layers are all layers except for the ignore raycast layer.

polar acorn
#

There's no way to change the default raycast layers, so you can't add another exclusion from it

frigid shadow
#

I understand that when we create a raycast that layer is excluded from the mask automatically, so what you're saying is there is no way to add another layer like it.

wintry quarry
frigid shadow
#

I'll have to change every raycast in the project then

wintry quarry
#

How many could that possibly be

frigid shadow
#

thats the thing, I have no idea, could be hundreds of scripts

wintry quarry
#

Why not just search it

#

how do you have no idea

#

isn't this basically just a matter of using the Search and Replace function in your IDE?

polar acorn
wintry quarry
#

you could be done in like two minutes

polar acorn
#

That layer doesn't do anything. It's just the default value of the mask parameter in raycast

#

There is technically a way to change that - rewrite the entire raycast engine but with a different default parameter

frigid shadow
wintry quarry
#

Step 1:

  • Make a static constructor on a class that stores custom layermask in a static variable, e.g. with ~LayerMask.GetMask("MyCustomLayer", "IgnoreRaycast")
    Step 2:
  • Search all your Raycast calls and add the layer mask
wintry quarry
frigid shadow
#

alright I'll give it a go

timber tide
#

Oh hey didnt know GetMask was an array

wintry quarry
#

Yep it's a params varargs parameter

frigid shadow
timber tide
#

ye I always make some LayerUtility class when starting a larger project because of the nature of changing layers and breaking things

frigid shadow
#

makes sense, gotta keep this in mind when starting my next project.

Hello, I would like to reference my class "MoveFeedbackTrigger" in this class "NetworkCharacterController" that I use but is not mine but I do not know why I can not, I imagine that it must come from the fact that it begins with "namespace Fusion" (line 1)? in which case I must put a using before that? or that kind of thing or that it is "sealed" or "unsafe" maybe

Screenshot_45.png
slender nymph
#

the issue is because it is in another assembly. you really shouldn't be modifying that anyway, just create another component that you attach to the same object and interact with it that way

winter creek
slender nymph
#

sure that would work. or if you really need to reference your own code in there you can go learn about unity's assembly definitions

winter creek

why can you not just do that immediately after calling the Move method from whatever other object is doing so? it's not like you will see any difference

Thanks guys I had the operators in opposite If statements 🙂

#

For some weird reason I can't delete a gameobject i created :>

chrome apex
#

I still struggle with how the code loop works. For example:

#

!code

eternal falconBOT
chrome apex
# 
void Update()
    {
        if (Input.GetMouseButtonDown(0) && Play.play && !clickedOnce)

        {
            clickedOnce = true;
            mousePosition1 = Input.mousePosition;

            if (Input.GetMouseButtonDown(0) && Play.play && clickedOnce)

            {
                mousePosition2 = Input.mousePosition;

Etc etc. I'm trying to get the first click and keep it detecting the second click, but this won't work, right? It will just exit the loop at the end of the frame. So what do I need to do?

slender nymph
#

that's not a loop at all. those are if statements, and since the second is nested in the first and all of its conditions will be true by the time it is evaluated, then both of them run in the same frame

chrome apex
#

I'm talking about the code loop since this is in Update

#

the code is looping over and over

slender nymph
#

don't think of it as a loop because it isn't looping, Update is just being called once per frame

chrome apex
#

oh wait

#

do I need to do the first if then write a method for the second one

#

that way I prevent it being called again and agagin

#

right?

slender nymph
#

i think you need to rethink what you are doing here, because as i explained already if the first if statement is true then the second will then evaluate to true since it is inside of that first one and the only different condition is immediately set to true as well

chrome apex
#

that's true, I could just keep it to false, you're right. The second will always be true then

#

but still

#

I am trying to wait for first click. I save the screen position of the click in a vector2. Then I need to wait for the second click, save the second vector2 position and so some stuff

#

so should I do the first if statement and call a new method with the other if in it

#

that will work, right?

#

so the second click won't be called once per frame

slender nymph
#

another method won't suddenly make your logic any different. you need to rethink how to structure this, particularly how you want the conditions to work

chrome apex
#

yeah but the other method will flip the bool again, so the first one will stop looping after the first click

#

I think that checks out

slender nymph
#

because, again, both of these if statements will be true in the same frame, they are not detecting separate clicks. they will be true from the same first click

chrome apex
#

I understand that

#

but won't putting the second if logic into a method I will call prevent that?

slender nymph
#

how

chrome apex
#

ok I will just write it out and post here

#

oh wait, is it because input.getmousebuttondown is a bool

#

and it resets only after the frame ends

#

calling the method and all the logic in it will happen in the same frame?

#

is that what you're saying?

slender nymph
#

i'm saying that because of how your logic is currently structured, both of your if statements are true within the same frame because the second one, which is nested inside the first (meaning the first has to be true in order for it to even be evaluated), is made true because the only difference in conditions between the two is immediately changed once the block for the first if statement is entered. there is no delay, they are not evaluated in separate frames. they are both true in the same frame. i do not know how much clearer i can be.

chrome apex
#

yeah ok I got an idea

#

I will type it out and post it here

# 
 void Update()
    {
        if (Input.GetMouseButtonDown(0) && Play.play && !clickedOnce)

        {
            clickedOnce = true;
            mousePosition1 = Input.mousePosition;

            Invoke("GetSecondClick", 0.1f);
        }
    }

    void GetSecondClick()

    {
        if (Input.GetMouseButtonDown(0) && Play.play)

        {
            mousePosition2 = Input.mousePosition;
            clickedOnce = false;
        }
    }
#

Is this better?

slender nymph
#

lol no because if you don't click the mouse button exactly 0.1 seconds after you click it the first time that will never work.

chrome apex
#

ohhh

#

I thought the method would wait until click

#

damn

#

I thought I was on the right track at least lol

burnt vapor
#

If the question is about implementing double clicking somehow, then I assume this would be natively available, right?

slender nymph
#

why would it?
you need to sit down and think exactly how your logic should play out then write the code for it

burnt vapor
#

Otherwise in an Update script just store a timestamp when you clicked and compare this against the next time a click it caught

#

Timestamps are always so underused

slender nymph
#

seems like they just want to get the position of the first and second click. they've not mentioned anything about any timing or whether it is a double click

chrome apex
#

So would a while loop or something do what I want?

slender nymph
#

no

chrome apex
#

I know I would ideally need to know more but imo by far the best way to learn is by doing

slender nymph
#

the best way to learn is by learning, not skipping the "learn how basic if statements work" part and jumping right in. if you cannot figure out that you just need to separate the if statements then you need to go !learn the basics

I am just confused by monobehaviour

slender nymph
#

you're clearly confused by more than just monobehaviours if you cannot follow your own logic

chrome apex
#

To be clear, I can make an entire game in playmaker without looking anything up but it functions compeltely differently than code and monobehaviour

#

Knowing playmaker kight have been a hinderance to me

slender nymph
#

so think about how you would accomplish this in playmaker then use that logic to form your c#

#

logic is just logic.

chrome apex
#

see

#

I did

#

and it lead to this

#

so that's not true

slender nymph
#

then either it wouldn't have worked in playmaker or you need to go learn c#

chrome apex
#

yes it would

slender nymph
#

prove it

chrome apex
#

lol man

#

have you used playmaker

slender nymph
#

i don't need to have used playmaker to understand that the logic you used is completely flawed

chrome apex
#

in playmaker, I would just get mouse 1, save first position, leading to second state with get mouse 1 and save other position

#

that's it

#

would take seconds to write

#

Please don't talk about playmaker if you don't know it.

Anyway, I think I figured it out. I need to use else for the second click

slender nymph
#

lmao you still haven't proven that your previous logic would have worked in playmaker (hint: it wouldn't have because both conditionals being true in the same frame would mean that both positions are the same)

#

at least it appears that you've finally taken my advice and given thought to how this should work

chrome apex
#

I have shipped games with playmaker

#

I know how it works

#

not like c# at all

slender nymph
#

okay smart guy, show me it working with both conditionals executing in the same frame. that was your logic before and you claimed it would have worked in playmaker

chrome apex
#

I would just put next frame event leading to the second state

#

and boom

#

ez

slender nymph
#

that's different logic

chrome apex
#

but there is no such thing as writing ''next frame event'' in c#

slender nymph
#

no, but as I already pointed out Update is called every frame and you were nesting your if statements so that they were both true in the same frame, that's been my whole fucking point this entire time

chrome apex
#

yeah ok I understand what you're saying

#

but playmaker doesn't use ''update'', just states

#

if you need something in the next frame, you just put next frame event. If I could do that here, I would

slender nymph
#

it doesn't matter that it doesn't use a method called Update. what matters is the actual logic you used.

chrome apex
#

I would just add ''next frame event'' but I don't know how to do that

slender nymph
#

as you've already determined, you would just use an else if

#

because Update is called each frame and you want the conditions evaluated in separate frames

queen adder
#

Is this whole argument about how to register double clicks

slender nymph
#

it's about detecting separate clicks, not necessarily a double click

#

and of course how logic is structured

queen adder
chrome apex
#

yes it is and I finally figured it out

queen adder
eternal needle
# chrome apex I would just add ''next frame event'' but I don't know how to do that

from skimming through this, it doesnt even look like you'd want to specifically check the next frame either. its not possible that the user can click on consecutive frames
the new input system can already detect double clicks with delay
It really looks like you could just put both checks in update, either check if its the first click or 2nd

slender nymph
#

yeah they just needed to use else if instead of nested if statements. provided they don't change that last bool they are checking at the end of Update or something

chrome apex
# 
 void Update()
    {
        if (Input.GetMouseButtonDown(0) && Play.play && !clickedOnce)

        {
            clickedOnce = true;

I have this now, should work

Thanks but it can be frustrating sometimes. Playmaker taught me to think a lot, lot differently than what c# requires me to do

slender nymph

this is why i said you need to take a moment and think about exactly how you want your logic to play out

this also isnt really a c# issue, Update only exists in unity. the logic doesnt change no matter what language you use

Again, not sure what the use case is here

chrome apex
#

the use case is as follows:

queen adder
burnt vapor
#

Because a double click happens within a short time span?

chrome apex
#

I have an array of objects, doesn't matter specifically. But I want the user to click on position 1, then position 2 whenever, and spawn the object such that its X scale is between position 1 and 2

#

there is no time limit once the user clicks once

burnt vapor
#

I see, the code looked a lot like a sort of double click. Nevermind then

Is this really the case? I never had a problem playing P2P games, neither did any of my friends.

slender nymph
#

i wouldn't agree that ISPs just don't allow it, but the average person definitely wouldn't know how to forward ports. it is possible to use P2P with some sort of relay server though or NAT punchthrough so that you don't need to forward ports. that's a discussion for the #archived-networking channel though
(also steve is unlikely to respond as that is nearly a 2 week old post and he left the server anyway)

mellow saddle
burnt vapor
#

Oh, looks like the temper got to him

eternal needle
mellow saddle
brave compass
#

From a technical standpoint, P2P is the same as it has been for over a decade, as far as I know; possible through NAT punchthrough, but some routers don't support it so it's best to have a relay server as fallback.

But many just go straight to a relay server for more reliability and to hide player's IPs from each other. Steam used to offer a library that supported true P2P with a relay server as fallback, but now they only offer relay servers. They even claim a relay server can improve latency over p2p in some cases, because they have more optimal routing.

#

You get free access to Steam's Datagram Relay network as a Steamworks partner and you can even use it outside of Steam if you contact them. Destiny 2 uses it on PC and PS5.

#

Well, not really "free". Part of the 30% cut Steam takes. Free for free-to-play games.

Hello! i have an issue where when i walk backwards in my game and try shooting the bullets seem to randomly shoot left or right ``` void Shoot()
{
GameObject bullet = Instantiate(bulletPrefab, bulletSpawnTransform.position, Quaternion.identity, GameObject.FindGameObjectWithTag("WorldObjectHolder").transform);
bullet.GetComponent<Rigidbody>().AddForce(bulletSpawnTransform.forward * bulletSpeed, ForceMode.Impulse);
bullet.GetComponent<bullet>().damage = bulletDamage;

 timer = 1;

} ```

#

my bullet prefab does not have any rotation if that has anythign to do with it

How do I regenerate polygon collider 2D when I swap to a new sprite in the editor view?
It is using old collider and I assume the best way is to remove and add collider again.

Right click -> reset seems to work!

whenever my Spawn Method is called, this thing happens, the Parent object is teleported to the checkpoint (the big mushroom) but the child object isnt, anyone know why?

public void Spawn()
{
    playerHealth.Respawn(); //Restore player health and reset animation
    player.position = currentCheckpoint.position; //Move player to checkpoint location
    transform.position = currentCheckpoint.position;
    Debug.Log($"Position = {transform.position}");

    //Move the camera to the checkpoint's room
    //Camera.main.GetComponent<CameraController>().MoveToNewRoom(currentCheckpoint.parent);
    Debug.Log($"respawning");

Does the rigidbody not rotate?

delicate portal
#

The parent's, it doesn't

verbal dome
#

That sounds pretty weird. Why is it under a parent?

delicate portal
#

The arrow?

verbal dome
#

You generally don't want to move a parent of a rigidbody, doesn't work well with physics

verbal dome
delicate portal
#

Well the arrow goes down and up, and whenever you would press a button, the ball would explode into that direction

delicate portal
verbal dome
#

So is the arrow a child of the rigidbody

#

Or the other way around?

delicate portal
#

The arrow is the child correct

verbal dome
#

Okay that's fine.
Just use rb.AddForce(arrowTransform.up)

delicate portal
#

Yeah but that doesn't work for some reason, on the image thats what I got the gizmo for, it displays the arrow's up position

#

pretty weird...

verbal dome
#

Did you use AddForce or AddRelativeForce

delicate portal
#

Just a gizmo

verbal dome

And what code are you using for drawing the gizmo (white line?)

#

i needa make roll forward for my game how do i make it

burnt vapor
#

By rotating on the correct axis it makes it look like the object is rolling

#

Put it under a key, then use a coroutine to roll based on the object's rotation

verbal dome
#

Oh "roll forward"
Sounds like a basic dash mechanic paired with a rolling animation

low tide
#

YES

#

DARK SOULS ROLL

#

EXACTLU

low tide
verbal dome
#

What is "the" character controller script? Is it from a template?
Or do you mean you are using the CharacterController component in general

low tide
#

the template

verbal dome
#

Does it use CharacterController?

#

When you press the roll key, set a bool or enum that indicates that you are now in rolling state. Store the roll direction in a Vector3 variable.
When in this state, you should ignore normal movement and just move towards the roll direction. Or mix the two

low tide
#

Roll key is to be x

#

thats the code

verbal dome
# low tide

Do you understand the code enough that you can implement it from the instructions i gave?

#

Also !code

eternal falconBOT
low tide
#

i need to learn right

#

should i add the animation in the animation controller first or cahnge the code

verbal dome
#

I'd worry about the animation later when you get the roll itself to work

low tide
#

well how would i know it works

verbal dome
#

When you can roll..?

#

What are you asking lol

#

The animation isn't the thing moving you here. Although, it could be used for that with root motion i guess

#

My point is, the animation is just visual, so it can come later

low tide
#

ok then i will try

verbal dome
#

You can also probably find tutorials for this sorta thing if you struggle (search for "unity dodge roll" "unity soulslike roll" etc.)

can i ask how does this not work

#

the d key works but the S key doesnt

burnt vapor
# opaque lichen

The S key also works. You should see the log message in the console.

opaque lichen
#

it doest move my guy tttho

#

and nothing in the console

burnt vapor
#

If it doesn't, this component is disabled or not attached anywhere

#

Add a Debug.Log above this, see if you can see that one in the console

#

If you do, the other one should be visible as well

opaque lichen
#

for the d key?

#

nothing comes up in the console for the s key

burnt vapor
#

That's also possible

#

Whatever the case I'd love to see if an additional log shows if you added it here

wintry quarry
opaque lichen
#

im typiong sssss

#

so it works

wintry quarry
#

Then check the other two possibilities

#

like my character moves when i press d

#

Add the log

#

See if it shows

where?

Anywhere

#

Just add a log

opaque lichen

#

So what?

#

It's literally impossible for this to not work unless the whole script is disabled

#

You're wasting your own time

#

im doing this

#

Looks good, try it and see

wintry quarry

#

And screenshot your console when you did it

#

Save it

#

There you go

#

Your code is not saved

#

notrhing

wintry quarry
#

Save it

opaque lichen
#

im new asf

burnt vapor
#

I'm glad we managed to figure this out with only 40 messages

wintry quarry
#

Save your code

#

Then it will work

#

yueah

#

Though to be fair, it's fucking annoying that I'm trying to help and somebody else proceeds to ask for the literal same steps

#

No offense

#

yeah

thankjs

Good job team

i didnt know u have to save

this my first script ever on unioty

To be fair, outside of Unity .NET actually does it for you when you attempt to run code that gets compiled

#

Not in Unity, though

opaque lichen

nah ur mocking it

how do i make it so u have to wait once seocnd for eveyr key

#

look

#

this but when i hold it it just does it 100 times a second

#

i want to add a delay

#

hows that possible

verbal dome
#

You can do a timer or store a timestamp in a float when you perform the action

#

Before you can perform the action, you need to check if enough time has passed since the last time

#

(Time.time being key here)

#

Task.Delay would only make sense in an async method and it doesn't scale with timescale

hexed terrace
# opaque lichen

I haven't seen it mentioned, so just FYI - those yellow squares down the very left edge mean there are unsaved changes. The filename at the top on the tab label willl also have a * after it (a very common indicator that there are unsaved changes)

burnt vapor
#

Check against it, if Time.time passed it you can continue the script

ivory bobcat
#

Or Invoke later, custom timer etc

polar acorn
# opaque lichen

Wouldn't it make more sense to just run this on key press instead of key held

opaque lichen
polar acorn
#

So instead of futzing with timers, check for key press instead of hold

opaque lichen
#

but then you could spam the key

polar acorn
#

Yes, but is that actually a problem? Do you actually want a cooldown system or did you just not want this to run every frame?

swift crag
#

there are two separate questiosn you need to answer:

  • Can you hold the key, or do you need to press it every time?
  • Do you have to wait before performing the action again?

polar acorn
naive pawn
#

to be pedantic, greater than or equal to the number of things in the collection

swift crag
#

(Note that the first error in the screenshot -- the one talking about something in UnityEditor.Graphs -- is unrelated)

#

if that's getting blasted at you constantly, restart the editor

tiny wind
#

i just keep ignoring that thing

tiny wind
edgy tangle
# tiny wind oh wait, I forgot the buttons

If you care to take the extra step you can write your own more useful error by checking a) that the Buttons collection has any elements (Length or Count > 0)
b) that the index you want is a valid one (not negative, and not greater than the Length or Count -1).
So if it ever pops up again you could print a unique message for each case to tell you exactly what’s happening.

#

Although over time after you’ve run into this sort of thing many times, when you see an out of range exception you will know it’s one of those two problems.

        body.velocity = new Vector2(horizontalInput * speed, body.velocity.y);

        if (Input.GetKey(KeyCode.Space) && grounded)
            Jump();


    }
    private void Jump()

        grounded = false;
    }
    private void OnCollisionEnter2D(Collision2D collision)

            grounded = true;

Debug.Log, use it to check if stuff is as you expect

-# no bugs, only features 😉

Debug Log should literally have been the first line of code you ever wrote, so if you've gotten this far and you don't know what that is you should probably step back and do some more basic tutorials
