[polar dust]

you can select multiple materials at once, as far as im aware, there is no way to convert all materials in the project

[analog drift]

Ok got it, thanks for the help

[polar dust]

its funny, every time I have to convert a set of materials, I ask the same question "why cant this be automatic"

[wintry quarry]

the wizard finds them all at once for you

[polar dust]

it does!?

[rocky canyon]

yea.. in the Window> menu

under rendering

[polar dust]

oh cool!

now i feel silly for manually converting over and over again

[analog drift]

Haha, it's good that I asked

[rocky canyon]

lmao.. we all been there in some form or fashion

its kinda confusing how they have two different variants of it in two different Menus

[shadow rain]

NOOO WAAY

I FIXED IT

I JUST PUT IN CONTROLLER.VELOCITY.MAGNITUDE

SO HAPPY

[tender gazelle]

Hi Guys. So i have a problem, it shows that i didn't assign a groundCheck to my Character even tho i did. What should i do?

[wintry quarry]

you have another copy of your PlayerMovement script in the scene

on that other copy, you didn't assign the variable

to fix it - find and remove the extra copy

[polar acorn]

There error says that a PlayerMovement has no ground check. It does not say every PlayerMovement has no ground check. The one in your screenshot having it assigned simply means the error isn't talking about this PlayerMovement

[rich adder]

isn't that what we been saying for like ever ?
glad you got it tho lol

[mystic anvil]

@rich adder I debugged scene.buildIndex and it's always at 0

[rich adder]

which one are you grabbing, you gotta give me more context here..

show code

[shadow rain]

Yeah Srh

[green copper]

Can I reverse the process of checking a dictionary for a value? I have a dictionary of morse code character with ascii char as the key and a string of dits and dahs for the value, and I can search a string to see if it contains the key, can I do the reverse for translating back?

[verbal dome]

You can have a second dictionary that does it the other way around

[bold swallow]

I have a question about IronSource, where should I ask it?

[green copper]

Yeah, I figured that'd work, it'd just be a pain to redo and reverse everything

[verbal dome]

You can automatically populate the second dictionary from the first dictionary if you want to

[rich adder]

so thats the scene 0?
where is the log ?

[verbal dome]

foreach(var kvp in dict1) dict2.Add(kvp.Value, kvp.Key);```

[polar dust]

what is the question?

[bold swallow]

I have completed the implementation, released my game but I still get test ads on my game. I want to know how to switch them to live ads intead of test ads.

[tender gazelle]

I AM SO DUMB. I had a copy of the Script in my Chracter and i dont know why

[mystic anvil]

@rich adder Fixed it, it's working now

[hollow dawn]

I'm so confused on how to do this in the player movement script should I first add the mouse Input.GetAxis("Mouse X") & Input.GetAxis("Mouse Y")? or is that not needed? theres hardly any good sources online can't find a damn thing

[polar acorn]

Do you want to get the Mouse X or Mouse Y input values?

[hollow dawn]

I have no clue what's needed and what's not? I'm using cinemachine I can already move the camera without a camera look script. Its just that I don't know how to rotate the players rigidbody when looking around and making the movement camera relative so where ever direction I am looking at I can go in that direction.

[polar acorn]

All Input.GetAxis does is get you the amount of movement on that axis this frame. If your player movement script does things based on the mouse movement, you'll probably need to get the mouse movement

[mystic anvil]

I found a better solution Nav

[rich adder]

yup arrays are 0 index so its good to do that

[rocky canyon]

lol.. another day another dolla

[analog drift]

Hey I am making a driving motorcycle, imported an asset of the bike. I saw someone on youtube making a controller by having a sphere in the middle and programming it. Is that the easiest/optimal way or is there another better way to do that? If anyone did it before or knows anything about that?

[rocky canyon]

the sphere method is a solid "arcade" type setup

https://x.com/i/status/1107783904784715788

Kenney (@KenneyNL) on X

How the arcade-like car controller was made; big sphere rolling around, car model just copies position. Raycast down to find ground normal for car. Sphere gets force based on car model direction. Tilt/wheel turning/etc. all lerps. #gamedev #unitytips

X · Mar 18, 2019, 11:20 PM

but its up to you ultimately.. depends on how arcade <- -> realistic ur going for

[analog drift]

Is that good or no? What would be the pros and cons if you know?

[verbal dome]

One way to get your camera's horizontal rotation is Quaternion.Euler(0, myCamera.transform.eulerAngles.y, 0);
Now you have a quaternion that represents the side-to-side rotation of your character. You can then multiply a movement vector with that to make it align to the camera.

[rocky canyon]

its pretty simple not sure how well it'd work with a motorbike tho..

[verbal dome]

@hollow dawn It's really better if you just look up a tutorial, otherwise we'd probably need to just type out everything for you.

[hollow dawn]

I think I did it well it works and does indeed rotate the player/rigidbody . https://paste.ofcode.org/AEKYrpwzDymhmH4sMG5dJV

[rocky canyon]

the sphere is rolling and being pushed in the forward direction of the model... when u turn u rotate the car model.. and the whole time the car model is just tracking the rigidbodies position..

so everythings working together..

[verbal dome]

Yes, the "orientation transform" is another common way to do it

[hollow dawn]

so did I do it right?

[verbal dome]

Does it work like you need it to?

[analog drift]

I mean I have to make a motorcycle, plane and a boat, so now I am just doing research on what to do and what is best

[verbal dome]

I don't know how you are rotating orientation

[hollow dawn]

well yes it rotates the player/rigidboy

[verbal dome]

We weren't talking about rotating the rigidbody. You wanted to move relative to the camera

[rocky canyon]

when im in situations like that I like to go to the Unity Asset store.. find some things related to what i want.. import them and then i go in and try to reverse engineer them

to see how they all work

everything u mentioned theres an asset on the store already

car u gotta deal with friction, plane u gotta deal with gravity, boat u gotta deal with bouyancy

[verbal dome]

@hollow dawn Oh you mentioned rotation too, but yeah anyway my answer is about the relative movement only

[hollow dawn]

I did say "Its just that I don't know how to rotate the players rigidbody when looking around and making the movement camera relative" now I can rotate the player I'll do the movement camera relative

[verbal dome]

I mean you already have this line:cs moveDirection = orientation.forward * verticalInput + orientation.right * horizontalInput;
Which will work if you rotate the orientation transform correctly, only on the y axis

But I have no idea if you are actually doing that

[hollow dawn]

Orientation stores the direction your facing

[hollow dawn]

I think I might have done the rotating the player wrong when looking around it feels weird

[median heath]

can anyone help me i cant add image to sprite rendere

i jsut started unity

[wintry quarry]

make sure you imported it as a sprite

in the import settings on the image

[analog drift]

Yeah... I already imported the bike and got a prefab so I need to do research on that, but usually if I import a car or something they come with a controller?

[median heath]

lemme try

[median heath]

still not working

[rocky canyon]

can u show the inspector/import settings of said sprite

[median heath]

im seeing people drag images directly to sprite

[rocky canyon]

ya, b/c thats possible

[rocky canyon]

u see Texture Type?

#💻┃code-beginner message

[wintry quarry]

you didnt set as sprite

[median heath]

thx

:( for some reason its still not working

im dragging but nothing happens

i saved

[hollow dawn]

When I stand still and look around why does it look laggy? but when I move its goes back to being smooth?

https://paste.ofcode.org/FWYPELJzYpVVu2vapcw8ZB

[verbal dome]

I think you need to drag one of the "children" of the asset

Yeah, expand the asset from the arrow and drag its child sprite in

[median heath]

wait ill send a vid

[green copper]

can anyone reccomend a module or package for handling fancy text?

Thing kind of thing that handles each letter differently, so I can do things like change the colors of letters to fill them in, or make letters shake like in Slay the Spire

[hollow dawn]

I put HandleRbRotation(); in update instead of fixed update and it fixed it. since I'm rotating the rigidbody it should stay in fixed update then the problem occurs again how do I fix it?

[verbal dome]

Show that bird texture's settings again?

[verbal dome]

Sprite Mode should probably be Single

[median heath]

oh

finally

thz

it was the sprite mode that fixed it ig

[rocky canyon]

is it just me or have i seen this exact same scene like 4 times

i swear, the same colors, same grid, same monolith in the middle

anyway.. i think the answer is:

• move ur camera in lateupdate
• or use cinemachine

[hollow dawn]

lmao just confused BUT I used move rotation now it works but when looking around why does it feel weird?
https://paste.ofcode.org/N7iSzYeUkjPWk2wbteNn6c

[rocky canyon]

whats "weird" about it?

[hollow dawn]

Im using cinemachine

[rocky canyon]

you can try changing the camera's update setting.. usually its already set on "Smart"

thats usually fine in my projects 🤔

[hollow dawn]

I don't it just feels too smooth and when I am moving my mouse left to right it swings up and down idk just werid is there something wrong with my script?

[rocky canyon]

mayb? do u have any smoothing in ur code?

it def shouldnt go up and down for lateral movement

[hollow dawn]

it doesn't look like it...

maybe im just tripping

[green copper]

What is it called when a texture is split up like this so you can make squares with a center texture that tiles and the borders can extend so you can get a texture for any size

I'm aware of the concept but I can't for the life of me remember what it's called to look up how to implement it

[rocky canyon]

9splice

[green copper]

thank you

[polar acorn]

9 slice*, but I think most search engines will know what you mean

[rocky canyon]

yea that ^ lol

my electrician days are coming back

[hollow dawn]

when I try to look right or left really quickly it doesn't do it

this is me moving my mouse left and right quickly

its like too slow/smooth idk

how do I fix it?

[rocky canyon]

can u share ur camera script?

[hollow dawn]

im not using a camera script

just using cinemachine

[rocky canyon]

then just tweek the settings

mainly the Damping stuff

[hollow dawn]

this?

[rocky canyon]

not sure.. im using the newer Cinemachine

these seem important too

[odd sapphire]

what doess null mean cus in my language it means zero

[rocky canyon]

it means gone, not here.. poof.. non-existent

[wintry quarry]

it basically means the same in english.

[cosmic dagger]

You are creating (instantiating) multiple game objects and C# classes every frame. You will greatly increase performance from using object pooling . . .

[eternal needle]

use the profiler and see which part specifically is taking the most time. you can set a custom sample too so it shows as a different label
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Profiling.Profiler.BeginSample.html
That whole _dna part using strings too definitely isnt optimal. You should pool if instantiating is a major problem but also you dont need to use GameObject as your type for instantiating. you should use the component you directly want to reference as the type, unity will pass back the reference of the component and still spawn the whole prefab

[cosmic dagger]

Within DrawTree you instantiate the line renderer prefab as a GameObject every loop, and within an inner loop, you instantiate a fruit object prefab. Instead of using the type you need as the prefab, you're using GetComponent every iteration and then every iteration of the inner loop . . .

That is definitely costly since DrawTree is called every frame . . .

[acoustic belfry]

Hi, how i can make that an object an enemy spawn to get yeeted into the oppositive side of a proyectile and meele damage?
the thing is, my enemies explode into shards and sometimes items, and i want them to fly to the side of the damage, so how i can do that?

For now i did that the proyectiles explode upon contact, and a material that has complete friction, but its very buggy and sometimes it moves the shards i dont want to, and also the meele "push" doesn't work using this method

[verbal dome]

How are you moving it?

[slender nymph]

1. it is going to vary a bit due to fluctuations in deltaTime
2. depending on how you actually move the object there's probably a better way to get the velocity

so you're randomizing the velocity each frame

moveSpeed2 = Random.Range

moveDir * moveSpeed2
moveSpeed2 is the velocity here

[slender nymph]

or rather, it's the speed not velocity. velocity is direction multiplied by speed so that second line i pasted is the velocity

[wintry quarry]

Also you have the move speed variable right here there's no need to calculate anything

laser turret script https://paste.mod.gg/jujrxdxbrpub/0

[dense cargo]

if (laserBeam == null) {
  laserBeam = GetComponent<LineRenderer>();
}

You're saying if it is null then get the comp for it.. but that will just return null. If it's null you need to initialize it instead.

Otherwise, if it's not null, get the comp

[hidden fossil]

i have the component assigned

[dense cargo]

So then yeah, change if (laserBeam == null) to if (laserBeam != null) or if (laserBeam is not null)

[hidden fossil]

still not appearing

[dense cargo]

What's the material like for the line renderer? Is the line renderer thick enough and is it's color something other than totally transparent?

[dense cargo]

Hmm, well here's a few things I noticed though I'm not sure if any of them are the culprit(s)...
If the LineRenderer width is 0 or just not wide enough relative to the rest of your scene scale, it won’t be visible.
If firingPoint is null, laserBeam.SetPosition(0, firingPoint.position) will cause an error.
It also looks like you only update the LineRenderer positions when shooting begins, but the beam won’t move if the target moves. So you'll need to ensure SetPosition() updates every frame inside the while loop.
The laser could be rendering behind other objects as well, effectively being culled.

[hidden fossil]

nah the beam isnt even appearing for the linerendere positions

[eternal needle]

the width is still 0 in this screenshot, i told you this the other time #💻┃code-beginner message

[dense cargo]

Well, damn near 0, by the looks of it

[eternal needle]

oh i see this time the top value was 1.0, last time you had it at 0.1 which made the width a lot smaller

I would honestly just start with a new line renderer and recreate the one you have. when you create a new one via the right click menu, it should be visible

[dense cargo]

Setup as much as you possibly can in the inspector as well, easier to keep track of it all. That or do everything in code. lol

[sour fulcrum]

Iirc your not meant to use is and is not null on unityengine objects since they aren’t operator overloadable and miss out on some destroy related stuff

[dense cargo]

You may be right, I can't remember exactly how that works here

[cosmic dagger]

Facts. Use !unityObject or unityObject != null for objects derived from UnityEngine.Object . . .

[dense cargo]

Nice

[mystic anvil]

Wanted to ask how can I make object movement be responsive to the camera, so where I am looking is where the object goes.

[teal viper]

The issue is that you're using hardcoded directions in Translate. You should pass in directions that you want it to move in(presumably the camera forward).

Also, I'd recommend not moving an object via it's transform, if it also has a dynamic rigidbody(and you want physics to work correctly).

[mystic anvil]

What would I use instead?

[teal viper]

Setting velocity or adding force like you do with your jump.

Rb.MovePosition might also work

[mystic anvil]

In this case I would be using Input.GetKeyDown ?

[teal viper]

Depends on how you want it to work. You should check what GetKeyDown does in the documentation and what other input query methods are available

Also, I'd just recommend going over the beginner pathways on unity !learn:

[eternal falcon]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[mystic anvil]

I will have a look

I made it work with translate but the object looked laggy

[teal viper]

Yes, there might be several reasons why it's like that. Many of which could be caused by mixing up transform movement and physics.

Why can I not put these in those fields?
Im 100% sure they're specified correctly as Text mesh Pro, and the auratypetext and auracount ARE TMP, and the button is just a button.

it works now

Can a script with errors still be fully compiled? Because Unity stops compilation if errors found.

[stuck field]

No

You need to fix the errors

It can't compile with errors

Not because of unity stopping it for no reason, its like what happens when you get an error in a function, the function stops if not handled

[polar acorn]

It can't compile anything if there's compile errors anywhere. Even in completely unrelated scripts.

[queen adder]

Does anyone know why Impluse mode is not working as intended ?

[frosty hound]

Because you're using MovePosition as well

[queen adder]

Can you explain ? I dont understand , I am a dummy.

What actually happening in there ? I dont find any clue on documentation ...

[frosty hound]

MovePosition is you saying "from here, try to go to this new position"

Prior to that, you're using AddForce which is you saying "I'm going to push you this hard in this direction"

You're overriding the physics engine trying to achieve that by immediately telling it to be somewhere right after

Which you can see in your FixedUpdate how you are calling ProcessMovement right after ProcessSprintMovement

If you're attempting to add sprinting, you need to increase the distance you're traveling in ProcessMovement's MovePosition by increasing your moveSpeed while sprinting or using a separate higher value sprintSpeed while sprinting.

[queen adder]

I still dont get it . You are telling me addforce is pushing me in one direction. What is the point adjusting the moveSpeed to a higher value as well as sprintSpeed ? Since it is pushing into the same direction ...

[frosty hound]

I'm eluding to the fact you don't need your ProcessSprintMovement function at all

If you want to spring, just increase how fast you move in your ProcessMovement function.

[queen adder]

Wait , it works. I just adjusted the moveSpeed to a higher value as well as sprintSpeed...

No, because the code above I have simplified , the main thing that I want is whenever the player press SHIFT button , it will dash a certain distance , so ... there will be something OnSprint() function and check whether it is pressed down ...

[frosty hound]

In that case, you need to use a state machine so you're tracking what "state" your character is in.

And then, in your update loop, depending on the current state of the player, handle it appropriately

So that you're running your dash logic without the movement, jumping, wall climbing, swimming, etc. not overlapping unnecessarily.

[queen adder]

I will take it as advise and try , thanks for helping me out. Can I add you as friend ? Hehe , because there are still too many things I want to ask ... Can we ?

[frosty hound]

I don't do DMs, sorry

Feel free to ask questions here though, or share in #1180170818983051344

I've gone down that rabbit hole of making a character controller, so I know the pain you're about to face. 🙃

Can anyone help with this code? Im fresh in Unity and C# and just finished my first tutorial and now im about to do my first clicker game but this is not working for some reason and it says that the value is quote "assigned but it's value is never used" and even basic calculation like Money =+ 1; doesn't work. (Yes i know this could have been done better with FOR loop but i haven't learned that in C# yet so im doin the longer way)

[eternal needle]

!code in how to share code for the future.
your error is a basic c# misunderstanding, you are defining the variable again by using double variableName. you dont need to specify double everytime you refer to the global variable

You've made new variables in start that don't do anything. They exist until the function ends then vanish

If you want to use the variables you declared outside the function, don't create new ones

[eternal needle]

you'll gain a lot if you go through c# basics first, there is a intro to c# link pinned in the channel

[rigid pike]

oh bruh

i was used to it working normally as far as i remember from c++

[eternal needle]

thats not how c++ works either

[rigid pike]

i could have sworn it works normally that way- i guess my memory is just bad

but when i remove the double, the variable is not colored anymore, is that normal?

even if i fix the "double variableName" it still doesnt add up the number

oh wait

[eternal needle]

you should really do basics of c# first

[rigid pike]

i think i found the problem

nevermind lol

[eternal needle]

your code doesnt add to Money, it simply reassigns it to the equation. if you wanna add to the current variable then its +=

=+ just means you're assigning it to a value and theres a positive sign

[rigid pike]

okay now it works, thanks, i will do the basics after this "game" im trying to make

but won't be general c# different from unity one? i mean in normal c# you don't have "objects" like buttons and all that

[eternal needle]

unity uses c#, its not a different language but it is on an old version. you probably wont be using the newer features in any beginner level guide

the idea of learning c# first is that you arent learning both unity and c# at the same time. it wont be fun when you have to learn new objects like a button in unity, yet also have no clue how to write the code that the documentation is telling you

[rigid pike]

how far should i go into basic c# so i don't overlearn c# code that i won't "need that much" in unity in general?

also, last question, where could i find some open source unity projects to look into to learn?

[naive pawn]

i mean, there's no harm in overlearning

[rigid pike]

my point was, at what point should i start doing more of unity than plain c#?

[eternal needle]

i usually say once u actually understand classes and instances of a class, any tutorial probably wouldve taught you loops, arrays etc. thats probably good enough to at least not get stuck on every line of code in unity.

[rigid pike]

I have another problem this time unity specific one (Atleast i think so). I put a gif as image source to a button, but the gif doesn't play it instead just stays as an image.

[frosty hound]

Unity doesn't play gifs

[rigid pike]

What am i supposed to do then

[frosty hound]

You either have to animate frames, or use a video player.

[zinc charm]

thanks, I investigated it and the main problem seems like the algorithm is simply too complex to simulate in real time. I will need to switch to another algorithm

[tender stag]

how come the "Found command!" is still called when i type in giberish

i'll type in "ffsggfdsjjhhfdg" as the command, and it somehow still finds it

[eternal needle]

i didnt look so indepth at the time to the actual logic but the points we raised at the time would probably heavily speed up your processing. the overall code didnt seem complex at all

[tender stag]

anyone know how to fix it

its honestly pissing me off now

how is it finding a command which doesnt exist

its the if(foundCommand.HasValue) that always has a value

[verbal dome]

Instead of just "Found command!", print some info about the found command and also print commandName

That's the first debug step i'd take here

(Also no need to use ToLower if your string comparison is ignoring the case anyway)

[tender stag]

this is what it said

[polar acorn]

How about printing some identifying properties of the command instead of just whether it exists and what type it is

Whatever Command is it probably has a name or something

[verbal dome]

Yeah they seem to have a name and some name aliases too

I haven't worked enough with nullable structs to know if there's any quirks I'm missing, but I don't see anything wrong with the code right now

[tender stag]

Debug.Log($"Found command! Name: {foundCommand.Value.Name}");

it doesnt even say the name

[verbal dome]

It's either null or empty

[polar acorn]

Okay, so the Command isn't null, it's probably just got null values

What is Command? Maybe it has some sort of "isValid" property or something

[tender stag]

command is the struct

[tender stag]

here is a screenshot

[polar acorn]

Ah, it's a struct. FirstOrDefault will return the thing it finds, or the literal default. Since Structs aren't nullable, it gives you a struct with its initial values

[verbal dome]

What happens in CheckDuplicateAliases?

[polar acorn]

Your linq query cannot return null

So has value is always true

[tender stag]

it just checks if any of the commands use the same alias and warns me to change it

[verbal dome]

So the default value of a nullable struct actually "has value" (HasValue is true)?

[tender stag]

oh alright

[tender stag]

so whats my best option

just loop through them?

[verbal dome]

Ohh right it's not a List of Command?, it's a list of Command

[polar acorn]

Yep. That whole linq query evaluates to command = default

[verbal dome]

Makes sense now

[polar acorn]

Instead of doing FirstOrDefault, store the result of the query in a list. If the list is empty, set foundCommand to null. Otherwise, set it to the first thing in the list

So, foundCommand = resultList.Count > 0 ? resultList[0] : null

[tender stag]

since the name is empty when it doesnt find it, couldnt i just add && !string.IsNullOrEmpty(foundCommand.Value.Name)?

[verbal dome]

Not quite this actually, the default value of Command? would have HasValue = false, but the Linq query doesn't know about nullability here

[polar acorn]

That could also work

[polar acorn]

Right. It's a list of a struct, that's getting cast into a nullable

And the default value of a struct is non-null

[tender stag]

ended up with this

thanks

[livid arch]

okay,

[rigid pike]

how do i make it so that a number doesnt get shortened to exponents?

[polar acorn]

It won't, unless there is code specifically telling it to do so

[rigid pike]

well then how do i make it not have exponent? i understood it the way that i have "something" in my code that is telling the number to get shortened but i don't. it automatically gets shortened

[naive pawn]

can you clarify what you mean?

do you just mean the stringification of floats?

[rigid pike]

this: From lets say 123456836839696 to 123.45E+24 for example

[polar acorn]

If you're printing the float, don't format it

[zinc charm]

@eternal needle I got the pooling but don't understand the instantiating by component thing you mentioned. how would I do that?

[verbal dome]

It does get automatically formatted

[rigid pike]

MoneyDisplayText.text = Money.ToString();

just this

[naive pawn]

specify a format
https://learn.microsoft.com/en-us/dotnet/api/system.single.tostring?view=net-9.0#system-single-tostring(system-string)

[eternal needle]

https://unity.huh.how/references/serializing-component-references#referencing-components-not-gameobjects
you just use the type you want to instantiate. this wouldnt really save you that much if you're using pooling since you wouldn't be calling GetComponent or Instantiate much anymore

[naive pawn]

it's always formatted to get into a string

if the output isn't what's desired, then specify a different format, that's all

[polar acorn]

Isn't the default format just going to give what you put in? I'll go fire up Unity and double check, I probably should have confirmed that first

[naive pawn]

"what you put in" as in the float, yes
but it's not always going to be just a decimal literal, it can have exponents

100f .ToString() and 1e2f .ToString() are gonna yield the same result

[zinc charm]

I don't think this works I get InvalidCastException

LineRenderer lr;
lr = Instantiate(lineRenderer, transform);

[verbal dome]

Did you recently change the type of lineRenderer field?

[polar acorn]

What type is your lineRenderer variable

[zinc charm]

LineRenderer

I assigned prefab

[polar acorn]

Did you drag the prefab in again after changing the type?

[verbal dome]

It wouldn't compile if it wasn't the right type

[zinc charm]

idk might be a runtime issue, the game acutally started and then throw this error

[verbal dome]

Assign none to the variable and assign it again

[zinc charm]

let me try this

[verbal dome]

It might be serialized as a reference to the old type

[verbal dome]

Hence this question

[zinc charm]

ok ty, assignin again solved the problem

[bold falcon]

hello, i have a question, im pretty new to the "new" input system. my question is about whether i have to reference a InputAction in each script in which i need it, or can i make a one reference in scripts with static instance of it, and use that reference in all scripts where i need it?

for example i have a InputManager script where i calculate all the angle for rotating to face the mouse and stuff like that, which works cuz i can read the value and save it to a public vec2. but with a button value, where i either need to subscribe a function to it or use "triggered" value within it, im not sure, or rather it doesnt work, so is it possible or do i need to make a new reference to the Actions asset and all the input actions in it anew?

when I try to add my project to github, gitattributes come up empty, anyone else have this problem...?

[magic pagoda]

can someone link me some sort of tutorial on grid systems..? Ive been looking for one but I havent been able to properly understand the ones that I watched I fear q.q

the best I could find was this one but Im... not exactly sure whats going on here...
https://www.youtube.com/watch?v=G7iPGJl37Xc

[queen adder]

void DrawNormal()
{
    Vector3 normalVector = -(planet.position - player.position) / (planet.position - player.position).magnitude;
    Handles.DrawLine(player.position, player.position + normalVector * 10f);
    SceneView.RepaintAll();
}

Why does this not show up in the editor?
It gets called by an editor button

[rich adder]

did you verify the method was called with breakpoints/logging ?

[wintry quarry]

because it's not public

or do you mean the Handles line doesn't show

if the latter, make sure you have gizmos enabled

Also:

Vector3 normalVector = -(planet.position - player.position) / (planet.position - player.position).magnitude;```
Is a super confusing way to write this:
```cs
Vector3 normalVector = (player.position - planet.position).normalized;```

[rich adder]

well what about grids? Unity has a built in component for it

[wintry quarry]

what do you want to learn/know about grids

definitely just use the built in component as mentioned

[magic pagoda]

Well not just tilemaps, but Im working on a tile-based tower defense... Ive tried but I wasnt able to code stuff onto those tiles, they were just sprites

[rich adder]

You can certainly use the Grid system for 3D as well (if thats what you meant)

I've done it myself, you can also place tiles with a Prefab brush that can use 3D objects

but yeah Tilemap would be only 2D.

[magic pagoda]

nono I meant 2D ^^;

I wanna attach components to the grids Im using, and I guess use them kind of like prefabs? Does that make sense?

[rich adder]

kinda. You can make prefabs out of them sure, it has helper functions for it as well V3 to Grid

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Grid.html

basically if you ever tried to make your own grids with like multidimensional array , this cuts the work in half lol

[magic pagoda]

Ill give this a read, thanks!! ^^

[robust harness]

Stupid question but Is there a way i can pass csharp Item = ItemManager.instance.itemSO[selectedIndex]; into ```csharp
public Dictionary<ItemsScriptableObject, int> itemSO = new Dictionary<ItemsScriptableObject, int>();

Item is of type ItemsScriptableObject if that matters

[wintry quarry]

I don't understand the question really. You haven't explained what itemSO or what you mean by passing something into a field

sorry I see itemSO is a Dictionary<ItemsScriptableObject, int>()

what do you mean by "passing it in"

passing what into what

with the goal of what

This is actually most confusing because we don't knwo what selectedIndex is

is selectedIndex an int?

[robust harness]

yes

[wintry quarry]

your dictionary is backwards

your dictionary is set up to look up an int by an ItemsScriptableObject key

If you want to do lookups in the other direction you need a Dictionary<int, ItemsScriptableObject>

or even just an array or list of ItemsScriptableObject

(if the indices are contiguous)

[robust harness]

the thing is i have itemSO setup like this in ItemManager.cs so i dont think i can do lookups in another direction ```csharp
public void ListItems()
{
foreach (Transform child in ItemContent)
{
Destroy(child.gameObject);
}

    foreach (var kvp in itemSO)
    {
        GameObject obj = Instantiate(InventoryItem, ItemContent);
        var itemName = obj.transform.Find("ItemName").GetComponent<TextMeshProUGUI>();
        var itemDescription = obj.transform.Find("itemDescription").GetComponent<TextMeshProUGUI>();
        var TypeOfItem = obj.transform.Find("TypeOfItem").GetComponent<TextMeshProUGUI>();
        var itemIcon = obj.transform.Find("itemIcon").GetComponent<Image>();
        var stackSize = obj.transform.Find("stackSize").GetComponent<TextMeshProUGUI>();

        itemName.text = kvp.Key.itemName;
        itemDescription.text = kvp.Key.itemDescription;
        TypeOfItem.text = kvp.Key.itemType.ToString();
        itemIcon.sprite = kvp.Key.itemIcon;
        stackSize.text = kvp.Value.ToString(); // Shows the correct count
    }```

[wintry quarry]

I don't see how this code is relevant to what we were just talking about tbh

you can do this code with an array or a list just as easily

or with a dictionary in the other direction, just as easily

for a dict in the other direction the Key and the Value in the KeyValuePair would just be reveresed

It's also possible to have two dicts, one in each direction, if you need to do lookups in both directions

You just need to make sure they're always in sync

[robust harness]

Ive never really worked with these since im a beginner but how would i then search for stuff like csharp itemName.text = kvp.Key.itemName; Wouldnt that just create the same problem just bigger

[wintry quarry]

As I mentioned the key and value would just be reversed

it would be kvp.Value.itemName

what's assuming you had a Dictionary<int, ItemScriptableObject>

if you had a list you would just be doing:

for (int i = 0; i < myList.Count; i++) {
  String name = myList[i].itemName;
}```

[zinc charm]

i did everything you guys said and game runs 4x faster. algorithm itself is simple but the amount of calculations increase exponentially so it slows down pretty quickly in the next iterations. can't use l-systems efficiently i guess

[eternal needle]

youd wanna probably look into the job system if applicable but its definitely not beginner level. im not sure how far you intend to take this algorithm and i really know nothing about this system you mention. but yea at a certain point you could just be trying to run too many lines of code and thats all

what your video had initially didnt seem like it was doing all that much truthfully, so i assume this can still be pushed pretty far without advanced topics

[gilded canyon]

if i have a dont destroy onload that stores settings of my game in the menu how do i make it so that the object doesnt duplicate every time i enter the menu scene

[eternal needle]

if applicable you really could even just precompute a ton of results and use that.

[eternal needle]

you can have a "bootloader" scene which is your entry point containing things like these. then that brings you to the main menu

[gilded canyon]

like a intro scene

[eternal needle]

either that or a proper singleton implementation will destroy duplicates on awake

it just means a scene before your main menu. it exists for the purpose that itll only be loaded once, because nothing ever sends u back to the bootloader scene

bootloader itself doesnt actually mean that and the term isnt related to unity but you can think of your scene in the same sense https://en.wikipedia.org/wiki/Bootloader

[gilded canyon]

i get what you mean

    void Update()
    {
        for (int i = 0; i < hearts.Length; i++)
        {
            if (i < HP)
            {
                hearts[i].enabled = true;
            }
            else
            {
                hearts[i].enabled = false;
            }
        }
    }

i have this code, and I want to make it so if hearts are 6-10, the 5 hearts change from red to blue depending on the amount, do I have to make another for loop here which starts at i-5 if i is bigger than 5, or is there a more efficient way

[polar acorn]

You can still have 10 heart objects, just make the last 5 blue and in the same position as the first 5. If your health is above 5, they'll activate and draw over the red ones. If they're disabled, they'll be hidden and you'll look through them to see the red ones underneath

[eternal needle]

the more efficient way here also would not be doing this in update at all. do this logic anytime the HP changes, which should only be through a public method or property

[white lagoon]

umm, the heart system is in a different script than all my player related stuff

okay nevermind, the 2 scripts are still on the same object

[polar acorn]

Great time to learn about events and properties

[bold swallow]

I have this script that theoretically creates 52 playing cards and puts them into an array. The problem is that in the for loops when I check with a Debug.Log, everything seems to be working fine, but when I got and check after the for loops, I only get the last card that was added

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

public class ShooterScript : MonoBehaviour
{
    public Card[] deck = new Card[52];
    public Card[] hand = new Card[5];
    Card tempcard = new Card();
    int k = 0;

    void Start()
    {
        //first we loop for all the suits (4)
        for (int i = 0; i < 4; i++)
        {
            //then we loop for all the values (13)
            for (int j = 1; j < 14; j++)
            {
                tempcard.value = j;
                tempcard.suit = (Card.Suit)i;
                deck[k] = tempcard;
                Debug.Log(k.ToString() + ". The " + deck[k].value.ToString() + " of " + deck[k].suit.ToString());
                k++;
            }
        }

        for (int l = 0; l < 52; l++)
        {
            Debug.Log(l.ToString() + ". The " + deck[l].value.ToString() + " of " + deck[l].suit.ToString());
        }
    }
}

public class Card{
    public int value;
    public Suit suit;
    public enum Suit {Clubs,Diamonds,Hearts,Spades};
}

The console looks something like this:

1. The 2 of Clubs
.
.
.
50. The 12 of Spades
51. The 13 of Spades
0. The 13 of Spades
1. The 13 of Spades
.
.
.
50. The 13 of Spades
51. The 13 of Spades

[grand snow]

if Card is a class you are modifing 1 instance and adding many references to the arrays...

[queen adder]

anyone know why visual studio not working for me i tried this

[white lagoon]

should i be making variables readonly if i don't plan on changing their value?

[bold swallow]

And what will I need to do, to have 52 instances?

[grand snow]

yes

if you want 52 cards with their own properties then yes you need 52 instances

btw you can do your i to suit cast in the upper loop to convert only 4 times

[bold swallow]

Well I want an array that in each slot has a card that has a value property and a suit property. What will I need to do?

[grand snow]

make a new card instance in your j loop

make new card instance, assign data (or define a constructor on Card), add to array, done.

int k = 0;
for (int i = 0; i < 4; i++)
{
    var suit = (Card.Suit)i;
    for (int j = 1; j < 14; j++)
    {
        Card card = new();
        card.value = j;
        card.suit = suit;
        deck[k] = card;
        k++;
    }
}

[bold swallow]

//first we loop for all the suits (4)
        for (int i = 0; i < 4; i++)
        {
            Card.Suit s = (Card.Suit)i;
            //then we loop for all the values (13)
            for (int j = 1; j < 14; j++)
            {
                Card tempcard = new Card();
                tempcard.value = j;
                tempcard.suit = s;
                deck[k] = tempcard;
                Debug.Log(k.ToString() + ". The " + deck[k].value.ToString() + " of " + deck[k].suit.ToString());
                k++;
            }
        }

[grand snow]

change K to not be a member var too

[bold swallow]

Done

[grand snow]

should be good now I think

[bold swallow]

Ok it works as expected now, thanks a lot!

[north kiln]

You can also do it like this:
for (var suit = Suit.Heart; suit <= Suit.Spade; suit++)

and directly iterate over the enum

[grand snow]

np np. Very important to understand how references work and how it differes between a class and a struct (reference type vs value type)

[north kiln]

Which would mean you couldn't accidentally use i in the place of j or vice-versa

Im getting this error but i've checked and all the objects are there. Any ideas to help?
NullReferenceException: Object reference not set to an instance of an object
DeckManager.DiscardHand () (at Assets/Scripts/Managers/DeckManager.cs:59)

[sick trout]

where it is

[polar acorn]

Look at the line the error is on. Something on that line is null but you're trying to use it anyway

[polar acorn]

On the console

[verbal hedge]

I've already had a look and i dont understand why it would be null

[polar acorn]

What is the line

[verbal hedge]

59: discardPile.AddRange(handManager.cardsInHand.ConvertAll(cardObject => cardObject.GetComponent<Card>()));
31: deckManager.DiscardHand();
17: StartPlayerTurn(); // Begin with the player's turn

[polar acorn]

There's a lot on that line can be null

Start loggin'

[verbal hedge]

on 59?

[polar acorn]

Yes that's the line the error is on

[verbal hedge]

thank you! 🙏 I'll try and see if i can find out what it is

[polar acorn]

discardPile, handManager, handManager.cardsInHand, cardObject, and cardObject.GetComponent<Card>() could all be null and break that line.

[verbal hedge]

didnt get anything back from this:
if (handManager == null)
{
Debug.LogError("HandManager not found");
return;
}
turnManager = FindFirstObjectByType<TurnManager>();
if (turnManager == null)
{
Debug.LogError("TurnManager not found");
return;
}

time to test the rest

[verbal hedge]

would you recommend i go backwards until it works again?

and then I can just redo it

[ivory bobcat]

    Debug.Log($"Discard pile: {discardPile}", this);
    Debug.Log($"Hand Manager: {handManager}", this);
    Debug.Log($"Card in hand: {handManager.cardsInHand}", this);
    discardPile.AddRange(handManager.cardsInHand.ConvertAll(cardObject => cardObject.GetComponent<Card>()));
```Any of the references that print out *blank* would be null.
If you're still getting an nre when none of the above are null then likely a card object is null.

[verbal hedge]

I managed to get rid of the error but thank you!

[verbal hedge]

Does anyone know why my enemy sprite appears behind my canvas image despite being a higher layer?

[slender nymph]

that doesn't seem like a code question. but also i believe it depends on the canvas render mode whether it will sort sprites above UI (this could be incorrect as it has been a while since i've done much with sprites)

[verbal hedge]

ah where should I ask then?

[slender nymph]

#🔎┃find-a-channel

[verbal hedge]

ty, also you were right, turn out that i just had to change the render mode to world space

[slender nymph]

i'm not 100% certain, but i think screen space camera can also sort world sprites above UI

okay

[wet pivot]

I am setting the rotation of an object like this:
characterModel.transform.rotation = Quaternion.Euler(0, 0, 0);
and for some reason it keeps setting the y value to -180. I don't understand what's happening here.

[keen dew]

How did you check the y value?

[wet pivot]

In the inspector

[keen dew]

The inspector shows the local rotation, the code sets the global rotation

[wet pivot]

oh snap i get you. I am setting the rotation on a child object so that may be why this is happening

I changed it to transform.localRotation and it's working as expected

Thank you!

[warm mason]

this was working fine all day, why am i getting this error now?

not sure what im missing D:

i know 😄 the highlight in the picture is unintended

switching it to just TextMesh fixed it, maybe the name is different?

doesn't work, but either way im not using a canvas anyways, im using it with 3d world space so that wouldn't apply anyways

it seems like tmp might just not be installed lmfao somehow

or something

idek

oh sheesh, my whole project is blowing up

everything isn't working now when its suppose too

seems like its not recongnizing any of the libraries 0,o

no idea wy

[keen dew]

Close VS, go to Edit -> Preferences -> External Tools -> Regenerate Project Files in Unity and reopen VS

[warm mason]

i think.. it worked? thanks 😄

yeah it worked

[burnt vapor]

1. They are not libraries, they are namespace definitions
2. The whole point is to be able to reference code from other namespaces. Randomly adding System.Collections.Generic is not going to help them with TextMeshPro
3. They already had UnityEngine.UI included, it just isn't being recognised. That's the whole problem

[true siren]

Can someone help me fix the gradlew.bat --no-daemon -b

i can temporarily fix it by downloading gradle.bat and pasting it into the temp file of the unity project but this dose not fix it forever.

[teal viper]

You're saying it as if it's an error that everyone knows about and reads about it in the morning newspaper while seeping some coffee.

[frozen star]

can you run a unity build in windowed mode? (non fullscreen) If so, can you detect OS level drag and drop into the unity program?

[strong wren]

Unity might not implement those OS features for you, but you can access OS specific APIs like any other C# program.

[pure seal]

After installing the .net sdk, vscode still shows it as missing. I have looked up solutions on reddit and tried it but it does not work.

I have the extension to install it as well

[teal viper]

Did you try restarting the PC?

[pure seal]

yes

[teal viper]

Check the environment variables as the error suggests then.

Did you install the .net sdk or .net runtime?

[pure seal]

the .net sdk

[teal viper]

Then check the environment variables

Also try pinging it for info in the command line.

[woeful schooner]

am i crazy or is this just
wrong
like that condition is objectively true but no matter what it will never read true in the log (and i have an if statement a little later using the same condition that also never activates)

[rare basin]

it's a floating point issue

use can use Mathf.Approx(-3.5)

[woeful schooner]

in the condition? alright, thank you
i'll go try that

[rare basin]

that -3.5 you see in inspector in reality could be like -3.50000000000001

or so

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Mathf.Approximately.html

[woeful schooner]

well the thing is i've just frozen the movement and manually moved it to -3.5 by typing into the inspector because i've been struggling with this for a minute
so i don't think it would be, but yeah i'll try approximating it

[rare basin]

it doesnt matter

[woeful schooner]

alright

[rare basin]

also can you show the hierarchy

of the object you want to read transform for

it also might be that you are reading transform.position.y (world position)

and comparing it to local position in the inspector

[woeful schooner]

it was local position, yeah
i just changed the check to be transform.localPosition.y instead and that's fixed it
thank you so much!

[rare basin]

np

i'd still use Mathf.Approxmiately just to be sure

[burnt vapor]

No excuse not to use Mathf.Approxmiately, even if you are sure the value is the exact same

[woeful schooner]

yeah, i'm using it now- i've just never seen it before since i started with c# and apparently never ran into enough of an issue with floating point values to find out about it

[keen cargo]

It's pretty much an universal issue in programming

You might've been super lucky to not get it elsewhere

It's just how floating point values work, they're both accurate and inaccurate in a sense

[woeful schooner]

i dunno what to say
i've just never come across mathf.approximately and i've made a solid few movement systems and whatnot

[keen cargo]

It's a good practice to keep in mind

[woeful schooner]

yeah, i will from now on

[keen cargo]

There's a couple other handy best practices in the pins, take a look at those too

Especially the vector calculation

[earnest wind]

will this be the best way to make a "region" rendering?
so that it turns on the objects in the region when you go inside the trigger?

or would there be a better way than iterating trough each object?

[frosty hound]

That works, yep.

If these objects are always together, you could child them to a shared group container parent and just toggle that parent instead.

Or you can associate a container object with this trigger, and whenever a new object that has to be hidden/shown with it is added, child it to the container.

oh my god I did it, solving the problem feels so amazing, I checked the output in vscode, it showed the path it used to try and find the dotnet sdk, and I found the word homebrew, so I tried installing it on homebrew and it worked

[teal viper]

Homebrew? I assume we're not talking about windows..?

[verbal dome]

Do you have gizmos enabled?

This is a code channel by the way

[tender stag]

anyone got a better way of storing nested commands?

similar to what im doing

[verbal dome]

I'm not sure if it matters in this case 🤔 other than the potentially annoying warning

Assuming you aren't going to actually reach the depth limit of 10

[tender stag]

yeah i aint

what command could possibly have 10 arguments

[verbal dome]

It would definitely be an issue if you had cs public struct A { public A nested; }
Because each struct would need to have a value for its nested struct, which would have a value for its nested struct and so on

But you have a list so I don't think it really matters?

[tender stag]

im using a list

[verbal dome]

I'd almost want someone from Unity to confirm if it's an issue or not

Logically, I don't think it is because the first empty list stops the recursion

[willow shoal]

hi! how to fix this script? my player after touch on left he keep move slowly. i just need just normal move. i trying find script for me. can some one help? ```CS
public float speed;
public VariableJoystick variableJoystick;
public Rigidbody rb;

public void FixedUpdate()
{
Vector3 direction = Vector3.forward * variableJoystick.Vertical + Vector3.right * variableJoystick.Horizontal;
rb.AddForce(direction * speed * Time.fixedDeltaTime, ForceMode.VelocityChange);
}

i know i need one line of code delete or change so

[verbal dome]

You mean it doesn't stop after you stop turning the stick?

[willow shoal]

but I don't know which one

yes

[verbal dome]

The simplest fix is to add some linearDamping on your rigidbody component

Rigidbodies don't slow down automatically unless there is linear damping ("air resistance") or they collider with something and have friction

[verbal dome]

Do you need help finding linear damping here?

[willow shoal]

rb.linearDamping = 20;

i found

from unity help

[verbal dome]

Sure you can do it in code, or just change it in the inspector

[willow shoal]

this is it?

[verbal dome]

It's right there

[willow shoal]

ok!

where add this for my script?

public Rigidbody rb;

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

   void OpenParachute()
   {
       rb.linearDamping = 20;
   }

   void Update()
   {
       if (Input.GetButton("Space"))
           OpenParachute();
   }

OpenParachute(); is answer but where

[verbal dome]

Do you really have a parachute in the game or did you just copy this from somewhere?

[willow shoal]

i just found in official unity help web

[verbal dome]

You don't need code if you don't need it to change during gameplay

[willow shoal]

i just copy past and learn how i twok

[verbal dome]

Just change it in the inspector

[willow shoal]

oh im stupid

YES! thats it

thank you

[coral pilot]

Hi all, I am new to unity and am really confused by some of the things that are happening when using the behavior scripts. Firstly, when I edit the X it's actually editing the Y, is this due to some rotation that I have set on the object I am trying to move? Also, if I don't start the object at exactly (0,0,0) then the object seems to grow a mind of its own and move all over the place. Finally, when I am editing this position (X), why are other coordinates (Y,Z) being affected when I never told them to move in the script?.. Some of this is very confusing to me could anyone help out?

{
    void GetValue(string value)
    {
        if (float.TryParse(value, out float newPosition))
        {
            Vector3 beforePosition = transform.position;
            
            transform.position = new Vector3(
                newPosition,
                transform.position.y, 
                transform.position.z);
        
            // Debug.Log($"Y {beforePosition.y} -> {transform.position.y}");
        }
    }
}```

[tender stag]

ended up doing this

i know its definitely not the best way

but im not getting the error

[zenith summit]

Are there record structs in unity?

[brave compass]

Unity officially supports most of C# 9. Record structs were added in C# 10. So, no. There are some methods to force Unity to use a newer C# version. As long as the features you use don't require runtime support and are just a language feature, it's doable. I don't know if record structs require runtime support.

[cosmic quail]

unity is getting coreCLR in a few years though, that will probably make unity support C# 10

[minor robin]

I'm searching for a good inventory guide on youtube is there any recommendation from someone that has followed a guide?

[white lagoon]

how do i get the magnitude of the horizontal velocity from the rigidbody

[verbal dome]

I think you just want the absolute value of it

Mathf.Abs

[verbal dome]

Or do you mean on the X and Z axes?

Just ignoring Y?

[white lagoon]

so i just have to do Mathf.Abs(rb.velocity.x), there is no way to use .magnitude here?

[white lagoon]

2d game, there is no z axis on the rigidbody

[verbal dome]

A single axis does not have a "magnitude"

[polar dust]

Magnitude is the length of a vector

[white lagoon]

i mean it can be positive and negative, magnitude ignores the sign, at least in mathematics

[verbal dome]

That's what Abs does

Makes it always a positive value

[naive pawn]

yeah that's what magnitude is, mathematically

unsigned value of a scalar, |x|
magnitude of a vector, |v|
distance from the origin of a complex number, |z|
cardinality of a set, |A|

kinda fun to think about

[rocky canyon]

syntax voodoo

[rocky canyon]

whats the best way to rotate an object on a local pivot to a min and max range..

many ways to do it.. and to work out the bugs i believe my code got convoluted.. just curious what other people do (use) in this situation

[rich adder]

Clamp?

[rocky canyon]

nah i mean i have a clamp

im talkin about the actual rotation..

u could movetowards a euler prop..
or u could slerp..
etc

[rich adder]

ohhh yea.. I always used Slerp for rotations not sure if its fine

[verbal dome]

Slerp is fine if you don't care about which axes it rotates around to reach the target rotation

Since it takes the fastest route

[rich adder]

there was this aweosme post I saw a while ago. Pretty cool visualizing
https://x.com/i/status/1176137498323501058

Freya Holmér (@FreyaHolmer) on X

📏Lerp vs Slerp⭕

• Lerp interpolates in a straight line
• useful for interpolating positions

• Slerp rotates around (0,0)
• useful for interpolating directions

[rocky canyon]

i have a particular model thats all whacked out in blender -> unity import.. when its oriented the correct direction (while having a container object [the collection obj in blender].. Z and Y both rotate it on the same global axis it appears.. lol.. it completely ignores the gizmo/pivot/local settings... after thorough searching i figured out that the collection is 1,1,1 as it should be w/ 0,0,0 rotation.. yet all the objects facing north and south come in with also local coords of 0 on the X but the ones facing west and east come in with a -90..

soo i can offset that in blender by also changing that 1 object to have a -90 rotation and not applying it.. but then the mesh faces the wrong way.. and i can fix that but its weird b/c the mesh is rotated weirdly in blender.. but the import to unity flips it the right way up..

this is a different issue but the reason i ask about rotation..

[rocky canyon]

yes, ive encountered this with some range dummies that fall down.. and need to be raised again...

but let me note this is the same type of object.. but since its facing North and South its pivot works correctly

[rich adder]

oh so its harder with that already "rotation" I think I get it

[rocky canyon]

sorry for the book

[rocky canyon]

it wigs out soo often.. and im trying to force accurate local rotations.. so i can use the script elsewhere

not sure wtf blender is doing to me

[verbal dome]

I don't follow what the actual issue is

All of these objects look like you'd want to rotate them on one axis only

[rocky canyon]

yes locally.. but in the video i show.. ^ the first one
fine when its oriented with the axis directly..
but as soon as i rotate it downwards.. that same axis with the local transform rotates globally

sooo the scripts dont respect the local transform method im using

isnt the inspector transform a local transform?

[rocky canyon]

affirm

i think the object is broken.. if its not aligned w/ the axis perfectly the transform rotation rotates it globally.. all the other axis' work.. so my script does work b/c it falls on the Z axis.. if it were the Y it wouldn't

should rotate like this..
but instead it rotates like this..

i mean i could leave it.. but it bugs me knowing that if i were to want to change the rotation of another different object that also imports w/ the -90 rotation (the ones facing west and east) the script isn't gonna work

i'll continue to get that weird issue where only 2 of the 3 axis's are actually axising in local space

ohh! heres a perfect example..

[rugged beacon]

how should i find and delete everything in dontdestroyonload

[grand snow]

keep references in a list somewhere and destroy them later using that

[hollow dawn]

Here is my script https://paste.ofcode.org/3atNS2diNnxa3bL3vRZxPQ9 I have a issue where for the walk speed I have to put the speed value around 50+ to get the player moving when its at 2 it barely moves. Any ideas why?

[grand snow]

@rugged beacon you may be able to get the Dontdestroyonload scene via scene manager and then get the scene root and destroy them that way? (not sure if this is possible though)

[eternal needle]

did you debug what the resulting vector of that AddForce is? if that vector is as expected, then it could be a setup with ur rigidbody. like friction, drag, or a heavy mass would make it move slower

[wet pivot]

When I'm using a Cinemachine camera, is it possible to keep the rotation the same when switching between cameras? I've noticed that if I face one way and then switch to another camera, it switches my view back to the way I was facing before.

[wintry quarry]

It really depends on the details

and hoiw those cameras rotate

this is also a #🎥┃cinemachine question

[wet pivot]

oh didnt notice that

I'll ask in there

[ocean loom]

How do i use the "TAB" button in unity, ive tried to use

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

public class ScoreBoard : MonoBehaviour
{
   public GameObject scoreboardUI; // Assign in Inspector

   void Start()
   {
       scoreboardUI.SetActive(false); // Start hidden
   }

   void Update()
   {
       if (Input.GetKeyDown(KeyCode.Tab))
       {
           Debug.Log("Tabbed");
           scoreboardUI.SetActive(true);
       }

       if (Input.GetKeyUp(KeyCode.Tab))
       {
           Debug.Log("UnTabbed");
           scoreboardUI.SetActive(false);
       }
   }   
}

but im having issue It wont show up

debug.log isnt logging either

oh and ive also tried a break-point in the code and that wont work either?

[wintry quarry]

Is Update even running?

Put a log OUTSIDE the if statements

if the logs aren't printing the code isn't running, a breakpoint isn't going to tell you any different.

[ocean loom]

okok lemme try this

[wintry quarry]

also make sure you're not ignoring any errors in console.

[wintry quarry]

BTW:

    void Start()
    {
        scoreboardUI.SetActive(false); // Start hidden
    }```

does scoreboardUI happen to be this very same GameObject the script is on?

If so, you're about to facepalm so hard.

[ocean loom]

yeah it is, also your previous thing was right the update isnt running

how do i get it running 😭

[wintry quarry]

well yeah you're deactivating the GameObject

[wintry quarry]

make sure the code is on a GameObject that isn't being deactivated

[ocean loom]

create an empty game object?

[meager cypress]

If you want to make something hidden while running logic, hide the component not the gameobject

[wintry quarry]

I don't care how you do it - you just need to separate this script from the object being deactivated

[ocean loom]

its on a "panel" since its UI

[ocean loom]

ahh okok thanks

[wintry quarry]

you could put everything inside in child objects, you could use a tottally separate object

whatever you want

[ocean loom]

Thank You so much, it works now. I was being very stupid 😭

[wet pivot]

I was setting the cameras active and inactive to switch between them. It seems keeping them all active and switching them by raising the priority has the intended result.

[cloud walrus]

Guys i know this isn't the correct channel for this but this is the most active channel and the one i get most of the help from,

I've posted about this problem since yesterday without receiving any real help, and i need help with it to keep up with my course

I've checked all types of unity tutorials of Unity Timeline and i've followed to the letter (ig) but none of them has worked out with me, like have this bug in my unity editor that i don't know how to fix

specifically in the first second, it's not even behaving as intended (like it isn't recording the first second at all)

[teal viper]

At the very least ask in #💻┃unity-talk
Code is totally unrelated here...

To answer your question, the initial state is considered default, so there's nothing to record. You should research how the timeline works and what it records in the key frames. Is it delta positions or actual positions? If it's the latter, you can probably hit some button to record the key manually. If not, you'll need to make sure your object is at the starting point every time.
Read the manual for the timeline.

And don't ignore community rules or you're risking to get banned.

[cloud walrus]

I really appreciate your help I did ask in unity talk but didn't receive that much help neither (this was since yesterday)
And I'll try your solution and delete this immediately
Thx btw

[teal viper]

If no one answered, then no one knows anything about the topic. Or your question is not clear enough. Do your own research while waiting for a reply.

[cloud walrus]

i really really did all of that i swear, i made my question as clear as possible and what problems i'm having and i did a research the entire day without a clear understanding of what i did wrong, but next time i'll ask in a more polite way i promise

[worthy tundra]

ik this is a stupid question but how do i get the input field to start accepting input without the mouse? like normally you have to press on the input field with the mouse to get it to start accepting text, but i want a script that makes it start accepting input when you press enter

[rich adder]

google is your friend
https://discussions.unity.com/t/automatic-selection-of-inputfield-ui/633738

[worthy tundra]

thank you

[worthy tundra]

doesnt work

[rich adder]

doesn't what work? what did you try

[worthy tundra]

    private void Update()
    {
        if (Input.GetKeyDown(messageKey))
        {
            messageInput.Select();
        }
    }

[rich adder]

put Debug.Log underneath .Select() , show a screenshot of the Log

[worthy tundra]

its working fine, sending a log once per press of the button

its a tmp input field of that changes anything

[rich adder]

show screenshot

[worthy tundra]

i pressed the button 3 times in a row

never played with ragdolls but id assume the gravity on the rigidbodies is on

[rich adder]

show where did you put the log in code

also dont crop the entire window for console

[worthy tundra]

    private void Update()
    {
        if (Input.GetKeyDown(messageKey))
        {
            LogMessage("Calling");
            messageInput.Select();
        }
    }

[worthy tundra]

why

[rich adder]

because there could be hidden/collapsed NREs messages

since you put log Before not After as it was said

[worthy tundra]

nre message?

[rich adder]

Null Reference

[worthy tundra]

there arent any

[rich adder]

Okay but many times someone else was hidden so thats why its wise not to crop such things

where is messageInput assigned ? that UI method normally works fine

there is also another method mentioned in the thread

[worthy tundra]

assigned in the inspector, its a child of the object with the script

[rich adder]

is the gameobject enabled?

[worthy tundra]

ActivateInputField, tried it too didnt work

[worthy tundra]

yes

[rich adder]

idk I was able to test it again, is working fine here 🤷‍♂️

are you pressing the correct key?

no idea if log its printing is fine ig

[worthy tundra]

i am, evident by the logs

[rich adder]

show me your hierarchy

I bet Event System is missing

[worthy tundra]

THATS IT THAKNS

[worthy tundra]

how do i deselect it when i press enter again

[rich adder]

probably similiar function to Select

[worthy tundra]

    private void Update()
    {
        if (Input.GetKeyDown(messageKey))
        {
            if (inputSelected)
            {
                messageInput.DeactivateInputField();

                inputSelected = false;

                return;
            }

            messageInput.ActivateInputField();
            messageInput.Select();

            inputSelected = true;
        }
    }

its a little 🥴 but i can optimize from here, thanks 🫀

[rich adder]

oh cool
I found this too undocumented but yeah Deactivate is probably better
https://docs.unity3d.com/Packages/com.unity.textmeshpro@4.0/api/TMPro.TMP_InputField.html#TMPro_TMP_InputField_ReleaseSelection

[meager cypress]

The documentation frustrates me so much I find myself vibe coding just to see examples of what some of their functions do

[rich adder]

"vibe coding" ?

😬

[teal viper]

I think it's pretty clear in most cases.
Is there anything specific you have issues understanding?

[meager cypress]

It's not the understanding issue, it's why does this even exist issue. Such as contactfilter2D

[teal viper]

If it exists it has(or had in the past) some purpose. Focus on what you actually do need, rather than investigating everything.

Contact filter is probably corresponding to its name: a data structure that provides some filter parameters.

[meager cypress]

Yeah and that's the thing. There's no information on what it actually does specifically

that's why it's frustrating

We already have layermask why bloat it?

[rich adder]

its filtering for the physics2d class

2dcontact has more filtering specific to 2d physics https://docs.unity3d.com/6000.0/Documentation/ScriptReference/ContactFilter2D.html

[eternal needle]

who says its bloat? https://docs.unity3d.com/6000.0/Documentation/ScriptReference/ContactFilter2D.html

Use a contact filter to precisely control which contact results get returned. This removes the need to filter the results later, is faster, and more convenient.
Is literally the 3rd sentence on the docs and all you need to know

[teal viper]

From the look at the docs, it seems to include many different filtering parameters, not just layermask.
The purpose is to filter collisions/cast results more efficiently. But you don't have to use it. You can filter them manually.

[meager cypress]

You can take that at face value but results shows in some cases it is NOT faster and I want to know why. I don't want the documentation telling me lies

[eternal needle]

I don't want the documentation telling me lies
I find myself vibe coding just to see examples of what some of their functions do
So the docs which tells you exactly what something does is lying, so you use a spam generator to teach you?

What kind of conversation are you expecting here? What kind of results was it not faster in? There is a lot more here to consider than just saying "results shows in some cases it is NOT faster and I want to know why". Which is something you've seemingly taken at face value because you dont know why!

[teal viper]

Everything in programming is context relative. There might be some scenarios where your own implementation would be faster depending on the context.
It is enough to know that it would be faster in most scenarios though.

[eternal needle]

I wouldnt be surprised if the "not faster" comparison was a case where the filter did nothing.

[rich adder]

my source is..that I made it the fuck up

[eternal needle]

even if it wasnt visibly faster in some cases, which is borderline obvious as to why that might be, the whole discussion is just incredibly silly. saying the documentation is telling you lies feels like tinfoil hat conspiracy.

[meager cypress]

Just say you don't know instead of pointing me to documentations and thinking you're helping.

If you cannot help someone, don't.

[eternal needle]

Thanks, I'll continue to help others as I have been 👍. I get you have frustrations with reading in general, which you pointed out in your first message. maybe try re-reading the conversation slowly and asking for more clarifying details in parts you're confused about

[teal viper]

Know what? There wasn't even any specific question?

All we heard is that you're being suspicious of the docs.

[eternal needle]

the message above the one they replied to was my answer on a case where it wouldnt be faster even. its clear they just didn't understand the conversation

[teal viper]

And while it's true that the docs can be misleading sometimes, it's generally correct and the only thing we can rely on, as the source code is not available. And the documentation is the next credible thing.

If there's a specific performance issue you're having, it would be so much more productive to use the profiler to analyze the problem and share the details here, instead of making ambiguous tests of the unity API.

[eternal needle]

Plus, when something says its faster, that doesn't mean it's a noticeable difference.
Talking about cases where it'd be the same speed (or negligibly worse) would imply the ContactFilter2D didn't find anything to filter out. It's going to be nothing in terms of performance for this to run.
For cases where it did filter something out, you have less results to filter through. Going through 4 results instead of 5 is faster. That might be an insignificant boost, yet its still faster and just less logic for you write manually

[meager cypress]

What are you even talking about? That's not what I'm doing.

I just said I have issues with the documentation not providing enough information to the point where asking AI is literally better than searching dead documents. That is ALL.

You, linking me to the docs, when my issue was the documentation is the most unhelpful response anyone could ask for.

Just say you don't know!

[eternal needle]

Well this just turned into a block, you clearly cant fucking read lol
they didnt even link you the docs!

[teal viper]

Asking AI is definitely not better. It would just lead you into a rabbit hole of lies. While it can be useful, it doesn't have a way to know how unity works under the hood, so whatver it tells you about it is assumptions at best.

[meager cypress]

Okay you saying it's not better is just stupid and false. I have gotten the result I needed. That's what matters.

[teal viper]

Again, don't know what??? You never asked a specific question

[meager cypress]

Okay, so what answer did you provide?

I obviously didn't ask a question.

[eternal needle]

There has to be a language barrier here, or they're just trolling at this point. Either way I think it's better we just don't continue this since they clearly aren't looking for help anyways. Just looking to complain I guess

[meager cypress]

Okay since you're having so much trouble I'll answer for you.

"We already have layermask why bloat it?"

[teal viper]

The answer is here:
#💻┃code-beginner message

[meager cypress]

If you don't know, do not answer. You don't have to provide a response thinking it may help when you're uncertain.

[teal viper]

I provided a response based on my experience reading docs and working with different game engines and other programs. If that's not good enough for you, I'm sorry.

[sour fulcrum]

I don’t necessarily wanna stir the pot here but one of the biggest problems with using AI to help here is that it will do exactly what your asking this place to avoid

If you ask chatgpt for example “why might x not be faster” because it’s a storytelling engine and not a programmer it’s going to do its best in an attempt to give you the best answer to that question, even if it’s not necessarily true

[meager cypress]

You are stirring the pot. If you don't know how to use AI you won't get results you want. It's not a magic fix-it all tool, implications that it is just makes you a fool. Just like any other tool, it's how you use it.

I'm pretty much done with this topic.

[slender nymph]

you should take the AI evangelism to the containment thread https://discord.com/channels/489222168727519232/1352599815770341479

[meager cypress]

I just said I'm done discussing it so take your snarky replies elsewhere

[sour fulcrum]

(It wasn’t snarky whatsoever)

[timber tide]

contactfilter exists because 2D and 3D rigidbodies use two different physic APIs

[woeful schooner]

both my conditionals here seem to be firing at the exact same time, is that correct?
i paused playback in the editor & manually moved my player over a platform (which is always going to be on a river, i'm essentially just making regular frogger), stepped forward one frame, and onPlatform became true while simultaneously the player got a game over

ah actually i've just managed to make things work, but i didn't address the simultaneous firing at all so if anyone knows whats going on there i'd still be happy to know

[keen dew]

Not simultaneously but both run after each other every time a trigger is entered

What probably happened is that first the river trigger ran which set onPlatform to false so the next check caused the game over, and then the platform trigger ran which set onPlatform to true

If the goal is to not get a game over when the player is on a platform then this logic doesn't do that

[woeful schooner]

ahh yeah i see
thank you!
like i said the code itself works now because i swapped some things around with ontriggerstay & enter but i really appreciate the explanation behind the logic

[timber tide]

I'd suggest just ditching tags all together and check a proximity around the player which will give you a list of colliders

this way you can filter out a list and iterate through them in one go

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Collider2D.Cast.html
Just an alternative way instead of using the OnTrigger methods

Ah actually you'd want to use overlap instead

how do i make scoll view automatically scroll to the newest item

[ruby zephyr]

I really don't understand why I can't access Scenes, I don't see any fix for my problem in youtube or google.

using UnityEngine.SceneManagement;

public class PlayLoadScene : MonoBehaviour
{
    
    void LoadGameScene()
    {
        SceneManager.LoadScene("SampleScene", LoadSceneMode.Additive);
    }

}

like, the function "LoadGameScene" should show in this list right

[stuck field]

Might be because the function is private

[ruby zephyr]

ill try making it public because I think on the tutorial that I watched they didn't put public or private at all

[stuck field]

👍

No modifer defaults to private

[rich adder]

most definitely was public

[worthy tundra]

how do i make scroll view auto scroll to the bottom

[rich adder]

https://discussions.unity.com/t/scroll-to-the-bottom-of-a-scrollrect-in-code/572012/15

[worthy tundra]

thanks

[ruby zephyr]

yo, if i put
using UnityEngine.SceneManagement;

SceneManager should show up on my IDE when I am going to type it right?

If it does not, even when I have the suggestions on my IDE turned on, would that mean I do not access the SceneManagement?

because I already made the function of the button and the script but it is not working

[rich adder]

it should if your IDE is configured

[ruby zephyr]

oh, it is working now when I tried it on void start,

But on button click it won't

[rich adder]

You have event system?

[ruby zephyr]

what is that?

I'm currently doing the main menu

[rich adder]

https://docs.unity3d.com/Packages/com.unity.ugui@1.0/manual/EventSystem.html
show your hierarchy

[ruby zephyr]

I do, should I put the object with the script on the event system?

[rich adder]

no

inspect event system in playmode and see what you pressing

[ruby zephyr]

it is pressed

it showed up

[rich adder]

what showed up where ?

[ruby zephyr]

to be sure, i will put a debug on the script of loadscene

[ruby zephyr]

event

event system in the hierarchy, in its inspector at playmode

[rich adder]

what about it

[ruby zephyr]

button name showed up on the inspector when I clicked it,

I mean, i thought you were asking me to test

[rich adder]

did you put a log in that function to see if it prints too

[ruby zephyr]

I am about to do it

is there a chance that unity would crash when I don't have the scene on my builds and I pressed the button with the script to load that scene?

[rich adder]

not likely unless you have it paused because of some error

show current code

[ruby zephyr]

I seem to be having a lot of problem in my Unity itself, this is kinda overwhelming

different crashes are showing like

It looks like another Unity instance is running with this project open.

Multiple Unity instances cannot open the same project.

[rich adder]

like total editor crash wdym by crash

[ruby zephyr]

and now it crashed again and a window showed up to Debug unity.exe

[rich adder]

when does crash happen

[ruby zephyr]

eveytime I test the button

[rich adder]

show the function you wrote

[ruby zephyr]

I will try one more, and I might do a screen record

using UnityEngine.SceneManagement;

public class PlayLoadScene : MonoBehaviour
{
    public void LoadScene()
    {
        
        Debug.Log("Button clicked!");
    }
}

heres for the debug

[teal viper]

Share the logs, share the code.
There's no much point in a video at this point.

Check the !logs after the crash.

I really don't know how to read a crash log

there isn't even an error showing up to my console, along with the Debug.Log

ohhh, I found the problem,

it is the Debug.Log code.. Idk why but when it is present my Unity crashes

everytime I play

that is just weird...

nvm fixed it

[teal viper]

How did you fix it?

[ruby zephyr]

well, I just removed the Debug.Log since it seems to be a problem to my Unity

now I am worried how I am gonna Debug.Log in the future

[frail hawk]

doesn´t sound like a solid soloution tbh

never heard of removing debug logs would solve problems

[ruby zephyr]

i know right, I feel like its my laptop that is having problems with Unity, like just how would my Unity crash like this when I only tried to stretch a UI in a canva using (Alt + Mouse Click).

[naive pawn]

have you tried updating to a later patch/minor version?

[ruby zephyr]

latest version?

well I'm currently working on 6000.0.26f1
but I'm updated at 6000.0.44f1

[teal viper]

As I said, you'll need to look at the editor logs after a crash.

Avoiding using debug logs is not a solution

[ruby zephyr]

Btw, this also keeps showing on a different crash

[teal viper]

This sounds like something that would appear after a crash when you open the project again.

[hot anvil]

I follow the code monkey tutorial and I'm facing this problem. Why the red blue and red landmark are not on the floor? Since floor position is (0,0,0) and player position is (0,0,0)
NB: Capsule position is at (x:0, y:1,z:0)

[wintry quarry]

Press Z

[short hazel]

Set these to Pivot - Local so the move tool is displayed relative to the selected object

[hot anvil]

Thanks guys, it worked

[hollow dawn]

Hey, I have this issue where I have to use a high value for walk speed, If I put it around 4 the player barely moves any ideas why?
https://paste.ofcode.org/h94DabMXWuQFT78iuWpYfd

[keen owl]

You can just multiply your walk speed variable in the code where it’s being called to amplify it’s value

Start with a smaller number

[teal viper]

Because it's force. So the final movement amount is affected by the rb mass, friction, damping

If you reduce the linear damping value, you could probably reduce the force amount as well.

[hollow dawn]

@keen owl @teal viper Thanks I just fixed it

[teal viper]

This is not a good practice. Magic numbers are bad.

[wintry quarry]

Just change the speed

Why add a magic number

[teal viper]

If you really need to change the value range, make the multiplier a serialized field as well

[wintry quarry]

One issue here is that "speed" is a misnomer for what that field actually does

[teal viper]

Or a named constant in code.

[keen owl]

Yes definitely create a field for speed multiplier especially if you are using the speed variable elsewhere in your code. Avoid magic numbers 👆

[hollow dawn]

like this?

[keen owl]

Yes

[teal viper]

And what Praetore said. This value is not speed in any way

It's force

[hollow dawn]

would it be a problem later on?

[teal viper]

It would make your code confusing to read. It might even confuse you in the future

[hollow dawn]

oh how would I be able to correct this?

[teal viper]

Call it force or movement force or something.

[hollow dawn]

Change this to movementForce?

[teal viper]

The variable name, yes.

And the speedMultiplier would be force multiplier as well

[hollow dawn]

Thanks 👍

[white lagoon]

i've read somewhere that using GameObject.Destroy() can be a bad idea sometimes, if I destroy the enemies using this and I have a prefab made for the enemies, will they come back when i load the scene again?

okay i tested it and it works, resolved

[wintry quarry]

1. GameObject.Destroy() doesn't exist it's UnityEngine.Object.Destroy()
2. destroying objects in a scene won't affect any prefabs, nor will they affect another instance of the scene you load later

[white lagoon]

is that in newer versions or

[wintry quarry]

See how it's greyed

[grand snow]

You can "destroy" an asset but only with an argument given to allow it. And this only works in editor ofc.

[wintry quarry]

GameObject is a subclass of UnityEngine.Object

that's why GameObject.Destroy works

but the function actually lives in UnityEngine.Object

[white lagoon]

it says to change it to just "Destroy(gameObject)"

[wintry quarry]

You could have written Component.Destroy or MonoBehaviour.Destroy too

[wintry quarry]

indeed

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Object.Destroy.html

[white lagoon]

is there supposed to be close to none formatting on this page

[wintry quarry]

no

[vestal tusk]

Hey guys, can anyone help me, ive been doing the unity tutorial 2d adventure game and just made a healthbar but now when i go into the game panel the whole thing is just blue?

[keen cargo]

Post a screenshot

[cosmic dagger]

I'd probably help to show how it looks. That description doesn't help us understand anything . . .

[gentle bone]

repeat the tutorial...

[wintry quarry]

if it's light/cyan blue it means shaders are still compiling.

Doesn't sound like a code question though

[gentle bone]

probably just missed 1 step or some config whatever... just go back and repeat the tutorial probably the mistake shows up..

[exotic tree]

I also have a problem since I use planets in my game I wanted to do a first person camera and the problem is with cameras horizontal movement because of it my player is just flying off the planet

public Transform player;
public float mouseSensitivity = 2f;
float cameraVerticalRotation = 0f;
// Start is called before the first frame update
void Start()
{

}

// Update is called once per frame
void Update()
{
    float inputX = Input.GetAxis("Mouse X") * mouseSensitivity;
    float inputY = Input.GetAxis("Mouse Y") * mouseSensitivity;

    cameraVerticalRotation -= inputY;
    cameraVerticalRotation = Mathf.Clamp(cameraVerticalRotation,-90f,90f);
    transform.localEulerAngles = Vector3.right * cameraVerticalRotation;

    player.Rotate(Vector3.up * inputX);
}

}
heres the code for the camera movement

whats the problem though

[keen cargo]

First solve posting your code

[acoustic belfry]

Hi, in a 2Dgame, how i can make that an enemy detects from where it attacks were? i mean the angle

my idea is that when it dies it technically shoots the shards and items to the oppositive side of the damage, so it can give the illusion the enemy exploded and the hit of the weapon sent the shards fly

the issue is, how i can make it detect the angle of the damage?

[rocky canyon]

what are u using to hit

w'e it is u can probably get the normal

then u just reverse it -normal

[acoustic belfry]

two things
one are proyectiles that have a ontriggercollision that checks if the enemy has a damage method, and use it
the other is the player who has a (thinking on making it temporal and replace it) overlap that when if the enemy is inside her overlap, and the player clicks right-click, it triggers it damage method

[acoustic belfry]

https://paste.mod.gg/qefvtvrpwpdk/0

better this

https://paste.ofcode.org/39MhiMEWJGMN4nsNRgY6pqr

[worthy olive]

idk, idk. the second if statement is just not working? I think glideForce gets overwritten somewhere? where, i do not know..

[polar acorn]

You could use some debug logs to see if it's ever running.

Make sure to put it in curly braces if you add another line to the condition body though

[acoustic belfry]

elaborate please ;-;

[rocky canyon]

how are u detecting the hit in the first place?

how u know a collision tkes place.. depending on what type of function ur using theres ways to get the info from the contact/hit poin t

[acoustic belfry]

Using onTrigger and the other using Overlaps.

It mainly just makes the method of this enemy get on

Enemy:
https://paste.ofcode.org/39MhiMEWJGMN4nsNRgY6pqr

[acoustic belfry]

thats the way i detect it

i think something went wrong with my message, holup

player

 private void MeleeAttack()
 {
     // Cast a ray to detect if an enemy is in range

     Vector2 MacheteRange = new Vector2(attackRange, attackRange);
     Collider2D hitEnemy = Physics2D.OverlapBox(machetepos.transform.position, MacheteRange, 0f, demons);
     Collider2D hitProyectile = Physics2D.OverlapBox(machetepos.transform.position, MacheteRange, 0f, proyectile);



     // If an enemy is detected, deal damage
     if (hitEnemy != null)
     {
         if (hitEnemy.TryGetComponent(out EnemyBase enemy))
         {
             enemy.TakeDamage(meleeDamage, 0);
         }
     }
     if (hitProyectile != null)
     {
         if (hitProyectile.TryGetComponent(out MortemRifleProyectile enemy))
         {
             enemy.Parry();
         }
     }

 }```

bullet

private void OnTriggerEnter2D(Collider2D collision)
{
    if (collision.transform.TryGetComponent(out EnemyBase enemy))
    {
        enemy.TakeDamage(riflebulletdamage, 1);
        push();

    }
}```

[wintry quarry]

For OnTriggerEnter2D and OverlapBox you don't really get any kind of directional info

so you can try to approximate it with e.g. subtracting the hit object's position from the attacker's position

or you can switch to some kind of cast

e.g. boxcast or raycast

and that will give you a hit normal

[green copper]

I've played games where you can turn a wheel or crank by clicking a point on the edge or handle and spinning your mouse in a circular motion to emulate spinning it

How would I go about implementing something like that?

For my system I'd need to be able to spin the wheel multiple times, i.e. where the handle not teleporting back to the start position is important, but keeping track of how many times it's turned, and in which direction, is also important

[rocky canyon]

ud have to use a boxcast or do some math stuff

https://docs.unity3d.com/2020.3/Documentation/ScriptReference/Collider2D.ClosestPoint.html

u could use this

[wintry quarry]

basically:

• each frame track the direction the crank is facing.
• Calculate the angle difference from the previous frame's direction
• Add that difference to the cumulative number of degrees you have turned.
• When you reach the desired cumulative value, do something

[acoustic belfry]

it says error...

[rocky canyon]
