[finite flower]

no, it's to rotate something towards something

[naive pawn]

do you need the clamp

[finite flower]

yes

[naive pawn]

how would it rotate to look at something behind and above you

if you just clamp it'd just look up and never get there

you'd probably need some more logic to handle that

[finite flower]

I don't want it to look behind me, that's the point

[naive pawn]

seems like that kinda defeats the point of making something look at something.

what's the overall goal here

[finite flower]

I want it to be able to look left, right, up and down, but only 90 degrees

[naive pawn]

limited from the starting rotation, or from the current rotation?

[finite flower]

from the current rotation (Idk how that changes because it's a child of the player)

it's a flashlight that follows the camera

[naive pawn]

and you want it to.. lag a little, from the camera?

or what

[elfin pike]

Have anybody made cinemachine pixelperfect solution to smoothly move between pixels

[midnight plover]

You want to aim with the flashlight like with a gun, right?

But separated from the cameras view

[finite flower]

It's a third person game and the light is mounted to the characters shoulder. I want it to aim where the camera is looking, but no more than 90 degrees from where the player character is facing.

[naive pawn]

i see, i don't think clamping particularly makes sense then
especially when working with a direction vector

could probably modify lookVector so it's not behind the player

[midnight plover]

you could clamp the euler angles or use quaternion.angle to check if its within your ranges for example.

[naive pawn]

does unity even have built-in utilities to convert from a direction vector to euler angles

[timber tide]

I wouldn't child it and just keep the max rotation values it can move

[naive pawn]

this is a code channel
try #🎥┃cinemachine or #🖼️┃2d-tools

[grand snow]

LookRotation is to a quaternion but this is a good lesson that we want to work in Quaternion as much as possible

[finite flower]

It has to be a child so it follows the rotation of the player

[elfin pike]

2d-tools last time was active, previouse decade

[finite flower]

That's what I was doing, but they said to use Vector3 instead 😭 😭 😭

[naive pawn]

doesn't matter

[hexed terrace]

do you mean... yesterday

[timber tide]

Well, it should be child to the body but not the face/camera more specifically

[grand snow]

I wouldnt to animate rotation

[elfin pike]

I was one, who yesterday was active

[finite flower]

Yes

[naive pawn]

the channel will be active if people use it correctly. be the change you want to see

[midnight plover]

Found this thread with some approaches, also from unity example scripts, that might help you there: https://discussions.unity.com/t/how-do-i-clamp-a-quaternion/606650/7

[finite flower]

Quaternion.RotateTowards does exactly what I want, until I try to clamp.

[timber tide]

it only needs to rotate on two axis as well. Not like a flashlight should rotate on the z. It's more that you want to clamp the y

well, clamp both y and x

[finite flower]

What 😭

at this point I'm just gonna scrap what I have and put a Cinemachine brain on it

[timber tide]

if we are to use local rotation, 0,0,0 rotation faces forward. You want to clamp the y and x to angles of 180ish

[finite flower]

90

and only the Y

180 is behind the character

[timber tide]

well 180 from left to right

or -90, 90 ye

euler should be fine, just don't modify the z

[finite flower]

I'm just gonna not worry about clamping it and figure it out later

[timber tide]

I'm just saying that if it's child to your character body then if it rolls, technically you don't need the flashlight to also roll

you just focus on that local rotational values

I'm feeling that trying to slerp from values not inside of that local rotational space may cause problems too so may need to do like the inverse quaternion method

too sleepy for this

[stoic sage]

Does anyone have any good tutorial or a forum on 2d hitboxes

[twin pivot]

!learn

[stoic sage]

[naive pawn]

hitbox is a concept, it's probably not gonna be called that in the tutorials

they'll be referring to colliders and stuff

[rich adder]

break your issue into smaller mechanics to solve

[sour fulcrum]

Can someone point out why I'm an idiot or if this is a problem with the serialized dictionary I'm using?
Code

    public bool TryGetValue(string category, out string value)
    {
        if (!valuesDict.ContainsKey(category))
        {
            string s = "Failed Check For: \"" + category + "\"\nDict Includes: ";
            foreach (string k in valuesDict.Keys)
                s += "\n\"" + k + "\" (" + (k == category) + ")";
            Debug.Log(s);
        }
        return (valuesDict.TryGetValue(category, out value));
    }

Log

Failed Check For: "Location Type"
Dict Includes: 
"#" (False)
"Name" (False)
"Directory Category" (False)
"Print Types" (False)
"Plan Type" (False)
"Description" (False)
"Location Type" (False)

I don't get why Location Type is returning false

[naive pawn]

log out their lengths, pretty quick & dirty check to see if there's maybe invisible characters

[rich adder]

most hitbox : either, a trigger collider or physics query like overlap / cast

[naive pawn]

if the lengths are the same, log out the charcodes to see if they're all the expected ascii

[sour fulcrum]

heard

i think there is a tiny invisible fucker

many thanks

is there a nice way to clean those up?

[naive pawn]

depends on what the tiny invisible fucker is, exactly

and where it's from

[sour fulcrum]

this is a google sheet off a www processed with my own csv parsing code

[naive pawn]

is the invisible character in the dict or in the input category

(and what is the invisible character)

[sour fulcrum]

in the dict but both come from that process, checking now

[naive pawn]

oh, a line ending

both cr and lf are whitespace so you could just trim the string

(or maybe check the csv - if it explicitly has the \r\n line ending, check the source sheet, if not, check your parsing code)

[rancid tinsel]

@sour fulcrum

[naive pawn]

and you're modifying it on an instance of the SO from the inspector?

[rancid tinsel]

yes

[naive pawn]

if you close out of unity (hopefully forcing a save, as the autosave seems to not work in your case), do you see the value in the SO .asset file change

[rancid tinsel]

no unfortunately

but what rob said in the other chat seems to do it

the save project

[naive pawn]

oh, nice

[sour fulcrum]

god bless 🙏

was a hanging line ending on my string[] array of the csv row

[echo copper]

what does that means?

[naive pawn]

you have an animation event set for a nonexistant target

[echo copper]

is animation event a script?

[rich adder]

no, its an Animation event.

[errant breach]

Hello, so despite creating a new projet and using an updated version fixing this issue, i still have this issue when rotating group. I dont know what im doing wrong but im pretty sure this is a common issue, does someone have an explanation on how to fix that please ? I would be very grateful.. Thanks !

Only the root does not create any issue. May i have did something wrong with the pivots ?

[hexed terrace]

this is a code channel, is there a code question here? Or are you just talking about manipulating things in the editor

[errant breach]

Both, because i will soon need to rotate my spaceship (barrel roll, etc) during the game with code and just like last time i will have the same issue. Im sorry if i am in the wrong channel but i was told to come here and i didnt find another place to ask for that. If im at the wrong place, feel free to tell me when i need to go

[hexed terrace]

your scale's aren't uniform (all the same, eg: 1,1,1)

Change teh scale for the gameobjects that move/ rotate to 1,1,1. And set the scale of children that don't need to move or rotate to the scale you want them to be

#💻┃unity-talk for topics with no specific channel / general questions.

[errant breach]

Soo it's that simple, woah. Thank you ! Thanks for the redirection too.

[errant breach]

now i have a question about an error i dont understand. Despite looking on the web, i have no solution for something that simple. Do you guys know how i can fix that please ?

[naive pawn]

you have a stray ; there

it's saying Move needs a body, aka the {}
the body you wrote isn't being picked up because there's a ; that completes the method declaration

[errant breach]

Too much python be like

Thank you ! 😅

[naive pawn]

python : is analogous to c-family {}

except with labels, switch/case, object initializers, i guess

[errant breach]

Im blind btw, sorry for taking your time

[stoic sage]

is it normal that i took so much time to understand colliders

2 fucking hours

just to make a collider trigger work

[sour fulcrum]

can be

[polar acorn]

It will be faster next time

[stoic sage]

dude i swear to fuck why is showing an error

yes i did reference it in the engine

ok why did it work when i removed the debug log?

huh

[polar acorn]

What does the error say

[stoic sage]

that hearDisplay is apparently not referenced when it literally was

no matter

it works now ig

[polar acorn]

What is the exact error it's giving you

[stoic sage]

nevermind

[polar acorn]

The variable hearts of Hitbox has not been assigned. You probably need to assign the hearts variable of the Hitbox script in the inspector.

[stoic sage]

i asigned the script itself im not sure how to assign the variable itself tho

[hexed terrace]

this ide isn't setup and that line of code with an error is incomplete..

[polar acorn]

So, this Hitbox has hearts set, so the error isn't talking about this one

[stoic sage]

oh

right

i referenced it into the script only

not the object

[hexed terrace]

you're doing it in a poor way already

Just do ⁨⁨⁨[SerializeField] private HeartDisplay heartDisplay⁩⁩⁩ -> assign in the inspector
Remove the gameobject field, and remove the getcomponent from ⁨Awake()⁩⁩

[stoic sage]

FINALLY OML

thanks yal

yall

althought a small issue

collision triggers twice instead of once

so it takes away 2 hp instead of 1

what could be the issue?

[naive pawn]

could be quite a few things

[polar acorn]

Show the inspectors of both objects

[naive pawn]

give some info about your setup so we don't have to guess through the plethora of possibilities

[stoic sage]

wich ones tho

hitbox and player or the heartdisplay

[polar acorn]

The objects involved in the collision

[rich adder]

it entered twice in the trigger?

[verbal dome]

Does the other object have 2+ colliders?

[stoic sage]

lemme look

huh

weird i thought i removed the second one

triggers once now yeah

thanks

man ive been making too many dumb mistakes

[hexed terrace]

they're only dumb if you keep making the same ones and don't learn from them

[night gate]

does anyone know how to instead of painting a texture on a surface on particle collision, instead create a 3d mesh

i wanna clarify i dont mean instantiating a mesh object on collision, i want to know if i can make a texture that instead of being a 2d layer of paint, is instead uniform 3d meshes

i feel like theres a specific channel for this but idk what itd be

[hexed terrace]

are you doing it via code?

[wintry quarry]

Maybe you want a VisualEffect (I.E. vfx graph) that creates mesh particles?

Yould also use something lower level like https://docs.unity3d.com/6000.3/Documentation/ScriptReference/Graphics.RenderMeshIndirect.html.

[night gate]

not a mesh particle, ive got a vine mesh i made in blender

and i wanna display that within every x amount of space covered within a texture paint

[sour fulcrum]

is that what these are for? (honestly don't know) https://docs.unity3d.com/6000.3/Documentation/ScriptReference/Texture3D.html

[night gate]

so like if it covered a 10x10m area, id have one placed at every 1x1 position

[night gate]

i dont think thats what i need

[verbal dome]

Procedurally with code or painting in the editor?

[night gate]

in the editor

[verbal dome]

I guess you'd use some tool like this
https://unity.com/features/polybrush

Why are you asking this in the code channel though?

Well, you could write your own tool, so maybe that's code related.

[rough granite]

There any good sources for learning HLSL?

[rich adder]

microsoft site probably

they developed it after all

[rough granite]

They did? Didn't know this, though i guess i know next to nothing about it

im trying to put the spacebar as the jump key how do i spell it so it rigisters

im using if(Input.GetKey(" ")

[slender nymph]

use keycodes then you can use the autocomplete in your configured IDE instead of relying on strings

[vestal cosmos]

what are keycodes

[cosmic quail]

https://docs.unity3d.com/6000.3/Documentation/ScriptReference/KeyCode.html

[vestal cosmos]

k thank you i will try that now

[spiral oak]

Is there any way I can prevent my AnimationTree from modifying the transitions between the animations??

[slender nymph]

is that a code question?

[spiral oak]

Sorry wrong server 😭

idk why I had this open

[vestal cosmos]

that worked but how do i make the jump smoother as right now it look as it if it is teleporting

[wintry quarry]

sounds like a bug in your code - usually caused by movement code that sets the vertical velocity to 0 each frame

the fix would be to fix that code. You'd have to share the code if you want more details

[vestal cosmos]

if (Input.GetKeyDown(KeyCode.Space))
{
transform.Translate(new Vector3(0, upwardForce * Time.deltaTime, 0));

}

public float upwardForce = 250f;

[wintry quarry]

This is the jump code - this is also really bad though

this is bad for several reasons

[vestal cosmos]

its my second day

[wintry quarry]

That's nice, and I'm telling you what's wrong

yes

[frail hawk]

line 15-33 could be replaced with 2 lines of code

[naive pawn]

AddForce with continuous forces should be in FixedUpdate, and should not have deltaTime applied - it will apply deltaTime for you

[wintry quarry]

the jumping would just be another force.

However your code has several issues:

1. You should not be doing physics in Update. Only in FIxedUpdate. (jumping can be the one exception to this for reasons that are complicated to explain - but basically because it's a one-off thing and not a continuous force)
2. you should not multiply forces by Time.deltaTime

[finite flower]

How would I get the relative velocity of my player? Cause the player rotates based on the camera, but rb.linearVelocity returns the world space values, not relative values.

[polar acorn]

You could convert it to local space with InverseTransformDirection:
https://docs.unity3d.com/6000.3/Documentation/ScriptReference/Transform.InverseTransformDirection.html

[wintry quarry]

relative to what?

[finite flower]

So, no matter where the camera is looking (third person), when the player is moving forwards, I want the forwards vector to be positive, etc

or where the player is looking

moving forwards = positive forwards velocity

[wintry quarry]

so you mean relative to the camera

then yeah just convert the world space vector into the camera's local space

[finite flower]

oh, no, I think I figured it out

how do I make it relative to something 😅

I know what I need to make it relative to for it to work

[grand snow]

I presume your camera is at an angle so that makes it a tad harder

[naive pawn]

sooo you're just going to ignore what digi sent?

[finite flower]

no, the camera is irrelevant to it, I think. The visuals of the player is rotating separate of the moving body, so I need to check the velocity relative to the rotation of that, I think.

[grand snow]

Then use the many functions provided by Transform to move to and from local space
#💻┃code-beginner message

[keen dew]

Setting the velocity to the player model's transform.forward * speed makes it go forward relative its own rotation. If the player can tilt up and down you can set the forward vector's Y to zero first

[finite flower]

I'm trying to get the velocity when it's moving

[grand snow]

then get it and transform the vector to be local

[finite flower]

idk how to apply that to the linearVelocity

[verbal dome]

var relativeVel = transform.InverseTransformDirection(rb.linearVelocity)

There's not much to it

[finite flower]

Do I not put the forward vector there?

[grand snow]

what are you on about

if you want velocity to be "local" to a transform then you use InverseTransformDirection on that transform

[verbal dome]

The transform has everything it needs to do the conversion.

[grand snow]

Are you sure you know what you are asking? Do you actually not need this?

[keen dew]

This is probably an XY problem

[finite flower]

I need to know the velocity of my player in local space. If the player is moving forwards, I need something saying it's moving forwards.
Forwards = 1 and Backwards = -1 no matter how the player is rotated. (not literally 1)

[grand snow]

Then what we said is correct if you have a Transform that describes this space

your player has a Transform btw

[finite flower]

playerVelocity = playerVis.transform.InverseTransformDirection(rb.linearVelocity);
This is what I currently have. playerVis is the variable for my chracters physical body, not the player object, because I want forward to be where the chracter is facing.

[grand snow]

that is correct

now Z+ will be forward relative to playerVis.transform

[finite flower]

This is what I'm getting when I'm standing still.

And those are constantly changing

regardless of if I'm moving or not

[keen dew]

If you just want to know if the player is moving forwards or backwards then it's Vector3.Dot(transform.forward, rb.linearVelocity). If that's > 0 it's moving forwards, < 0 it's moving backwards

[grand snow]

oh yea good idea. dot product is great

[naive pawn]

probably with a little epsilon to account for floating-point imprecision

[finite flower]

That's still returning worldspace 😭

[slender nymph]

transform.forward is also in world space so that doesn't really matter

[keen dew]

Vector3.Dot returns a single number that isn't in any space so that doesn't make sense. If it doesn't do what you expect then you're plugging in wrong values

[blissful stratus]

how can i remove this?

[finite flower]

It's working perfectly when I use transform.up, giving 1 when I jump and -1 when I'm falling, but for some reason the number just freaks out in any direction when I use transform.forward 😭

[slender nymph]

1. not a code question
2. unless you want to pay to digitally sign your game you'll need to select the option you've cropped out that lets you continue attempting to run it anyway

[finite flower]

It's just giving inconsistent numbers whenever i use transform.forward regardless

[blissful stratus]

oops my bad, so i have to pay to be aproved?

[strong berry]

Does anyone have a clear diagram of a basic block of code handy? Like with what a namespace is, what a class is, what a variable is, etc. clearly labeled? I keep running into information that seems to contradict itself and I really just want to understand these basic terms finitely. Even my textbook doesn't name them in order or in context.

[slender nymph]

https://stackoverflow.com/a/66582477

[grand snow]

if you want to compare to up then thats correct. Go read what dot product does to understand more what its doing

[cosmic quail]

it gets removed automatically if you put your game on steam

[finite flower]

How do I limit a float to whole numbers? Normalizing the numbers isn't working.

[verbal dome]

You mean "Round" it?

[cosmic quail]

https://docs.unity3d.com/6000.3/Documentation/ScriptReference/Mathf.RoundToInt.html

[slender nymph]

if it is just for display purposes, then you should just use the string formatters for numbers at the time you display it

[finite flower]

it's for being able to read the number reasons. I'm getting 1.13495807134958713409 kind of number every frame and it's impossible to debug that

[slender nymph]

right so that would be "display purposes"

[finite flower]

In the inspector?

[slender nymph]

don't rely on inspector values for debugging things

[verbal dome]

You can use Debug.Log or OnGUI+GUILayout.Label to debug it with formatting

[grand snow]

or the magic of a debugger ✨

This package is good though for good gizmos for this stuff too
https://github.com/vertxxyz/Vertx.Debugging

[finite flower]

Okay, so yeah, Vector3.Dot is giving seemingly random values 😮‍💨

[grand snow]

nah its bad input

If you just want to know if something is moving up in world space then use Vector3.up

[finite flower]

no

I want to know if it's moving forwards

the objective has not changed

[grand snow]

Then you need a more reliable reference for what "forward" is

[verbal dome]

Note that for example the first value here is just a really small number.
If your rigidbody is almost still then it might wiggle a bit or something and the numbers will seem "random"

[grand snow]

oh and you should normalise the velocity first before doing Dot()

[verbal dome]

Does that matter?

[finite flower]

even when it's moving in a straight line, it'll jump from -8.22397 to 2.2497 to 1.2497 to -5.234987

and just random

[grand snow]

if unity doesnt normalise it then yes

[finite flower]

Even when I did that, it just did the same thing

[verbal dome]

The sign of the result value of Dot would still be correct for non normalized input

In fact you can even use it to check the relative forward speed of the vector

For example Dot(v3.forward, v3.forward * 5) would return 5

Which is positive

So its moving forward and at speed 5

[grand snow]

but when we want a nice -1 to 1 range then normalising the inputs helps

[finite flower]

except when it doesn't

playerVelocity = Vector3.Dot(Vector3.Normalize(playerVis.transform.forward), Vector3.Normalize(rb.linearVelocity));

[grand snow]

TRANSFORM THE VELOCITY

[finite flower]

Yes, those are words

[naive pawn]

if you don't understand then say so instead of ignoring the advice

[grand snow]

we tried folks 🧱

[finite flower]

What does that mean?

[grand snow]

scroll up and read stuff

[verbal dome]

Thats only useful when we want to check similiarity of two vectors. Here it sounds like we just need the sign of the dot

[grand snow]

yes but what if they want a specific range that means "forward"?

[finite flower]

I just need to know if my player is moving in the direction it's looking 😭

[verbal dome]

Directional similiarity, i should add

[naive pawn]

@finite flower imagine you're bleeding out and someone tells you to use gauze to wrap the wound, but you don't know what gauze is.

do you a) ask, or b) completely ignore the advice because there's a word you don't understand

help is a two-way street

we cannot help if you refused to be helped

[verbal dome]

This is correct though (apart from the redundant Normalize calls).
If this value is less than 0, then rb.linearVelocity is 180+ degrees different from playerVis.transform.forward in world space.

[finite flower]

But it's just returning random values instead of being consistently positive or negative?

[naive pawn]

then you'd probably want to get the angle between directions rather than the dot product then

[naive pawn]

is this just trolling at this point

[grand snow]

yea both work

[finite flower]

I'm ignoring someone who only antagonizes instead of helps.

[naive pawn]

had a convo recently about this, defining angles would be easier than defining a dot product threshold since dot product isn't linear over angle

[verbal dome]

They only need to know if moving backwards or forwards, and a dot product of the world space velocity and some world space "forward" direction gives that. Which they are doing

[naive pawn]

trying to avoid a "too many cooks in the kitchen" situation here. rob and osmal are already giving perfectly good advice, just seems like you're ignoring it

[grand snow]

huh i thought it was linear ha 😆

[naive pawn]

also, giving advice about getting help is also "helping"

[naive pawn]

i did too lmao

[verbal dome]

Most of the code shown here should've worked so it's an input problem and/or some feedback loop

[naive pawn]

but nah 2 normalized vectors at 45° from each other have a dot product of sqrt2/2, since it's the cosine of the angle

[finite flower]

I thought that, but this variable is only used here. I made it specifically to see the velocity, and the rest of the variables return fine everywhere else I use them.

[naive pawn]

are they changing a lot or just a little
that X value is tiny

[finite flower]

#💻┃code-beginner message

[naive pawn]

and that's the rigidbody velocity?

[finite flower]

No, that's the value that's being returned when I use Vector3.Dot

[slender nymph]

can you screenshot the values? because i'd bet they are just really small numbers in scientific notation

[naive pawn]

ok, so that's.. not what i asked lol

i'm referring to this message #💻┃code-beginner message
what part of the inspector is this cropped from

(for future reference, a less cropped image would help give crucial context.)

[finite flower]

Same answer

It does the same thing

[naive pawn]

what same answer? that's the dot product?

[finite flower]

Those Vector3 values were from transform.InverseTransformDirection

[finite flower]

It returned random values

[naive pawn]

ok cool, that's part of what i was asking. now do those change a lot or a little

[finite flower]

Generally between 10 and -10

[naive pawn]

and they're definitely like, 7.43482 and not 7.43482e-6?

yeah yknow what just show more context directly please

feels like a very prolonged game of telephone here...

(use mp4 so it embeds in discord)

I know

[naive pawn]

i don't know if you know.

[finite flower]

I have to rerecord cause I need to revert the script

[stoic sage]

how can i highlight hitbox object only for inspector

so i dont have to move an invisible object in the inspector

[solar hill]

what

can you clarify what you mean

[naive pawn]

ok so it's basically just not changing at all, just microscopically fluctuating

[solar hill]

thats like −0.000000007

[finite flower]

That's using this playerVelocity = playerVis.transform.InverseTransformDirection(rb.linearVelocity);

[naive pawn]

right, and it seems to be relatively stable, as revealed by your console showing 2 digits being perfectly stable

[verbal dome]

And I bet the Y value is large because of gravity/some imperfect character controller code

[naive pawn]

i'm confused. was this the part that had issues? that's what i gathered from backreading and i'm not so sure i got it right

[verbal dome]

Make sure that the animator isn't modifying the root object's transform also

[finite flower]

This was the first thing I was told to try using to find if my player is moving forwards.
I was then told to use Vector3.Dot because it'll return a float that's positve when moving forwards and negative when moveing backwards.

[naive pawn]

yeah both of those work

[hushed sky]

could someone help me with this? im pretty new on Unity, im searching to change the image of a normal button with a custon image so is not just a square. I found the package manager is it there? or do i need to download from some place in internet a png?

[naive pawn]

those were offered as alternatives, not that one was better than the other

so i'm still confused. what's the issue

[hushed sky]

my point is im trying to find a safe place for unity to download images for the button

[verbal dome]

With code or manually?

[naive pawn]

the internet

[hushed sky]

manually like in the inspector

is there any safe place dedicated to unity things?

instead of just take it from google search?

[verbal dome]

Asset store

[hushed sky]

where would that asset store be?

[verbal dome]

This is a code channel. Not a general beginner channel

[finite flower]

Neither of them are returning a usable value that is positive when the player is moving forwards or negative when moving backwards.

[hushed sky]

there is many channels and i cant find one more suited rn

[slender nymph]

What would you consider a usable value to be

[finite flower]

it's returning a value that is positive if the player is moving +Z or +X in the world tho

[finite flower]

preferably a whole number

[verbal dome]

@finite flower Have you checked the value of rb.linearVelocity when you are standing still?

[slender nymph]

You haven't read anything that anyone has told you, have you. Nor the docs for Vector3.Dot

[finite flower]

I did and all of it is saying I should be getting 1 to -1

not 0.000007

[polar acorn]

Well, 0.000007 is between -1 and 1

[verbal dome]

So check your input values

If you are expecting something else

[slender nymph]

Yeah, a float within that range. It will only ever return one of those two specific numbers if it is perfectly aligned or exactly opposite

[naive pawn]

(if the vectors are normalized)

[verbal dome]

Is the rigidbody even dynamic? 🤷‍♂️

[finite flower]

It's returning 0 whether I'm standing still or moving 🤦 no clue how tho

[verbal dome]

So is the rigidbody kinematic?

[finite flower]

no

[slender nymph]

How are you moving it

[finite flower]

// The math for figuring out movement
        moveVec = move.ReadValue<Vector2>();
        moveLike = new Vector3(moveVec.x, 0.0f, moveVec.y);
        moveLike = Vector3.ClampMagnitude(moveLike, 1f);
        
        if(isClimbing)
        {
            x = playerVis.transform.up * moveLike.z;
            z = playerVis.transform.right * moveLike.x;
            isJumping = false;
            //rb.useGravity = false;
        }
        else if (!isClimbing)
        {
            x = cam.transform.forward * moveLike.z;
            z = cam.transform.right * moveLike.x;
            x.y = 0.0f;
            z.y = 0.0f;
            //rb.useGravity = true;
        }
        
        direction = x + z;

        float xSpeed = playerSpeed * 0.01f;

        finalMove = Vector3.Lerp(finalMove, direction * xSpeed, friction);
        normalizedMove = finalMove + Vector3.up * velocity.y;
        rb.linearVelocity = normalizedMove;

playerSpeed is 450 btw

[verbal dome]

To be clear, rb.linearVelocity returns (0, 0, 0)? How did you check this and when/where?

And is this a different script? Are you referencing the correct rb?

[tribal urchin]

I need help how do I make this block trigger an animation I’m trying to make a titanic sinking map ?

[verbal dome]

Trigger when something enters it, or when you click it? Or what

[tribal urchin]

When I click it

And also to trigger the sound source

[naive pawn]

https://screenshot.help btw

[tribal urchin]

Ik

[naive pawn]

anyways, give it a collider and something implementing IPointerXHandler and use a physics raycaster, iirc

[verbal dome]

Yep
https://docs.unity3d.com/2018.3/Documentation/ScriptReference/EventSystems.IPointerClickHandler.html

[tribal urchin]

It has a box collider

[finite flower]

I'm going to scream. It wasn't working cause I put it too high in the script 🤦

[rough granite]

Do the IpointerEnterHandler and IPointerExistHandler not work on 3d objects?

[verbal dome]

You can see example code in the link I posted. Then you need to find out how to reference the animator and audio source and play them inside OnPointerClick

[naive pawn]

not sure how you inferred that

i just said to use IPointerXHandler

[verbal dome]

That's what the Physics raycaster handles

[tribal urchin]

To clarify it’s not flatscreen it’s a VR game / map

[naive pawn]

it doesn't work on its own, no

[grand snow]

Example of using IPointerClickHandler to respond to pointer click
https://github.com/rob5300/Unity-EventSystem-Events-Example/

[verbal dome]

Yeah this is a decent usecase for unity events

[grand snow]

not present in that example but you can if you wanted

[rough granite]

You also said to use a raycast, so i was asking a question cause i was under the assumption they do as the documentation says used to detect if the mouse is over a gameobject

[verbal dome]

Oh my eyes garbled "Unity EventSystem" into "UnityEvent System" lol

[naive pawn]

i said to use a raycaster

it's what triggers the pointer event handlers

you may be thinking of the MouseXHandler stuff?

[rough granite]

Sorry never heard of raycaster, but i was thinking of https://docs.unity3d.com/2019.1/Documentation/ScriptReference/EventSystems.IPointerEnterHandler.html

[naive pawn]

afaik, you need a raycaster to trigger the events to begin with

[ivory bobcat]

Physics Raycaster is a component necessary to do what you're wanting

[grand snow]

Hmm if only there was a cool example that explained all this 🤔

[rough granite]

Cause i was thinking of a way i would've handled what they asked and you gave a different one. Where i would used the IPointer enter and exist to toggle a bool i misread you saying to use a raycast

[naive pawn]

i gave the one you were thinking of

(are you thinking of PointerExit, PointerExist is not an event)

[ivory bobcat]

You'll not be able to get around this. Ask for clarity if you're not certain of something @rough granite
The Raycaster is a necessary factor

[naive pawn]

https://docs.unity3d.com/2019.1/Documentation/ScriptReference/EventSystems.BaseRaycaster.html
see the description

not sure why you linked the 2019 docs though

[rough granite]

hmm now im confused never used a raycaster as far as i know of yet i have used the IPointerEnterHandler and IPointerExitHandler interfaces before

[naive pawn]

i guess go back and check then

[grand snow]

okay these work in UGUI because a graphics raycaster is there on your canvas for you
OTHERWISE you must add a physics raycaster/physics 2d raycaster to the camera to use these with the other colliders

[rough granite]

oh i see now thank you this makes more sense

[strong berry]

🙏

[grand snow]

This confusion is why i made a complete example

[rough granite]

yeah me clicking the link would've helped ~_~

[naive pawn]

have you tried looking that up, or checked docs (such as those pinned in this channel)?

you could also show the resources that apparently contradict themselves to ask for clarification

[strong berry]

1. Of course I've tried looking it up.

2. I'd like help from literally anyone but you because I've seen you be unnecessarily rude to everyone in this channel and I'm not here for that.

[naive pawn]

on point 1, some people don't lol. i'm not in your head

it's hard to clarify apparently incorrect resources without seeing the actual resources though

[tribal urchin]

To clarify the video is an example of what I'm trying to do but in my VR map can someone help me?

[naive pawn]

oh, this is vr?

[tribal urchin]

Yea

The video is a example of what I’m trying to accomplish to help clarify

[naive pawn]

i assume the intended input method in the vr version would be using the hand controls then?

i don't know what they're called

[tribal urchin]

yea

[naive pawn]

you wouldn't be using a raycaster for that i guess. the folks in #🥽┃virtual-reality would probably be able to give better advice about how to handle that

[tribal urchin]

Thanks

[surreal shard]

hi, i'm trying to get the camera to follow the player with the SmoothFollow script but the camera keeps snapping to a random position and stays there

[rich adder]

SmoothFollow script ?

[surreal shard]

i should probably post some screenshots wait

it's a script from standard assets as far as i can see

sorry if i'm being confusing i only recently started learning unity i know nothing

[rich adder]

those are pretty old, unity has new ones

probably even better new, it uses cinemachine which you should learn anyway

[surreal shard]

the course i'm following uses this version of unity

i should

go find another source to learn from shouldn't i

[rich adder]

should be fine for learning, the exploit thing is only in the build

is not that seriously it can be easily be patched with tool, but you can use latest LTS anyway if you want its the same editor..

[surreal shard]

this is what my screen looks like rn, the camera is supposed to follow the ball and the ball has some player controls on it that work fine

but instead it just snaps here, about 150 units away, and stays there

[surreal shard]

i kept getting errors related to the "input system" bcuz some of the scripts in the course use the old one i think

so to avoid that i switched to the version they specify

[rich adder]

!input

[radiant void]

How to Set Input

To set Active Input Handling, go to:
Project Settings > Player > Active Input Handling

• Input Manager (Old): Use the original Input settings.
• Input System Package (New): Uses the new input system package.
• Both: Use both systems.

[surreal shard]

did that

didn't work

[rich adder]

can just put it to Both and it works fine

[surreal shard]

ig i'll try again hold on

i don't remember seeing the both option actually

ok i opened the project, it was already set to both and apparently it works now

[gilded harbor]

Okay, I figured out the clamp issue for now. Now i'm having an issue with my rotator script. It works as intended for the most part, I mousepress an object, a ray detects the object and sends a signal to rotate the object depending on where i'm pressing. For some reason though, clicking on the right side (rightplane.name) makes the object spin endlessly, even though the left side is working fine. Why?

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

public class RotatorLogic : MonoBehaviour
{
    public float rotSpeed;
    public Collider leftplane;
    public Collider rightplane;
    public Transform pivot;

    public Camera cam;

    private RaycastHit israytouching;

    public string raycastedobject;
    // Rotation Settings
    private float rotatespeed = 700f;
    

    private bool mousepressed;


    private void Update()
    {

        Vector3 mousePosition = Input.mousePosition;

        Ray myRay = cam.ScreenPointToRay(mousePosition);

        bool RayTouching = Physics.Raycast(myRay, out israytouching);

        if (RayTouching)
        {
            raycastedobject = (israytouching.transform.name);
        }

        if (Input.GetMouseButton(0))
            mousepressed = true;

            if (raycastedobject == leftplane.name && mousepressed)  
            {
                pivot.transform.Rotate(0f, rotatespeed * Time.deltaTime, 0f);
            }
            if (raycastedobject == rightplane.name && mousepressed)
            {
                pivot.transform.Rotate(0f, -rotatespeed * Time.deltaTime, 0f);
            }
        else
            mousepressed = false;
        }
}

[rich adder]

bracket issue

you else never runs

right now the else is going based on if (raycastedobject == rightplane.name && mousepressed)

 if (Input.GetMouseButton(0))
            mousepressed = true;```
one reason writing if staments like this can mess you up

so yeah brackets are important for if blocks

[gilded harbor]

Oh my god thank you lol. I had to look up how to format an if else statement. I have a lot more learning to do. Thank you so much!

[rich adder]

btw you could technically just write it as mousepressed = Input.GetMouseButton(0);

since you have && mousepressedanyway

[gilded harbor]

Could I do that in the start function?

[rich adder]

no because it needs to poll it every frame otherwise it stays in one state, Start only runs once

[gilded harbor]

Thank you, that helps clean up this mess a little bit 🙂

[rich adder]

btw could also skip the whole string bit too, raycasthit which you named israytouching(confusing name btw is not a bool)
you can directly check collider
israytouching.collider == leftplane or israytouching.collider == rightplane
the "drawback" is you need to put it inside RayTouching otherwise iirc you get a null collider not the last touched.

fine how you do it for now, if it works it doesn't matter I suppose..

[rough granite]

I mean it does just only if if (raycastedobject.Rotate == rightplane.name && mousepressed) fails

[rich adder]

yes what I meant was it doesn't run how they wanted it though its whatevs lol

[rough granite]

Yeah fair, they also could've gone the route of deleting that bool instead of making it = Input.GetMouseButton(0) as it's seemingly useless in the given context

[gilded harbor]

Even if my current script already works, I'll do anything to help learn what exactly does what and better ways of doing things. Especially if it prevents unnecessary giant if/else statements.

[rich adder]

true but putting things in variables can make them more flexible imo

mousePressedUI_Icon.gameObject.SetActive( mousepressed)
etc

[crimson sluice]

I’m having trouble with the input system code

[rich adder]

trouble is vague, how can anyone help there 🤔

[ivory bobcat]

Your last else statement is attached to your last if statement. So if the raycastedobject isn't the leftplane, raycastedobject == rightplane.name would be true and raycastedobject == rightplane.nam would never be set to false. Thus the object will rotate indefinitely.

[crimson sluice]

Like the inputs aren’t showing on the console

Sorry I’m not the best at explaining things I’m very new to all this

[rich adder]

well we're not mind readers and frankly playing 20 questions sucks... you should offer as much detail possible

[ivory bobcat]

You'll want to provide any and all necessary data. If not, folks will have to keep asking you for information that should already be provided.

[crimson sluice]

Ok I gotchu so I’m using the system Input and I was having some issues with the c# script where I was having errors I just don’t know what to really put in for the c# for the charter inputs?

I don’t know if that helps at all I can give you them guys my code when I get home later tonight

[golden canopy]

it was some weird unity glitch mb

[naive pawn]

you should generally come ask when you're able to provide more info/context yeah, just a general tip

[kind skiff]

I am using scriptable objects but for some reason it is having this error. It keeps happening where at the start of the creation for the scriptable object it's fine but after some time it keep appearing this error. Do anyone know how to fix it?

this is the ERRor ------- MissingReferenceException: The object of type 'UnityEngine.GameObject' has been destroyed but you are still trying to access it.

this is error shown in Console when i try to test the game ? the object has been assigned in inspector . (Object Pooling)

[kind skiff]

Is the object being destroyed in the hierarchy?

[boreal sonnet]

after one fire --this error shows up

[kind skiff]

Can you check whether there is another script that is destroying the objects?

If you're returning to the pool the object will not be destroyed unless you tell it to

[boreal sonnet]

no the player doesn't destroy but the prefabs thrown is destroyed

[boreal sonnet]

oky

[kind skiff]

Yea but at the PlayerController Update function you are calling the Object Pooler which gets the Pooled Object but since it is destroyed but still remain inside your pool it causes the error

[boreal sonnet]

the player has only one script attach to it but the others has 2 scripts one to -- move and one to Destroy

[kind skiff]

Owhh but if you're already using a pool you do not need to destroy it

The object pool's main goal is to make it efficient by reusing the objects and do not need to keep on creating and destroy the objects

[boreal sonnet]

i know but trying to shorten the code ........listen destroy as the other prefabs from whom the player should avoid i'm destroying those

[kind skiff]

Can you show where the object gets return to the pool?

[boreal sonnet]

if (Input.GetKeyDown(KeyCode.Space))
{
// No longer necessary to Instantiate prefabs
// Instantiate(projectilePrefab, transform.position, projectilePrefab.transform.rotation);

        // Get an object object from the pool

            pooledProjectile.transform.position = transform.position; // position it at player
        }
    }

[kind skiff]

so did you delete the projectiles?

[boreal sonnet]

no

[kind skiff]

Isn't this where you retrieved from the projectile pool?

[boreal sonnet]

public GameObject GetPooledObject()
{
// For as many objects as are in the pooledObjects list
for (int i = 0; i < pooledObjects.Count; i++)

// if the pooled objects is NOT active, return that object
if (!pooledObjects[i].activeInHierarchy)
{
return pooledObjects[i];
}
}
// otherwise, return null
return null;
}

[kind skiff]

but you mentioned previously that the projectile throwned is getting destroyed

[kind skiff]

the issue isn't here

the object gets destroyed after it got returned to the pool

which is causing the error

[boreal sonnet]

yes

i dont know how should i fix it?

[sour fulcrum]

find wherever you destroy it and dont do that

[boreal sonnet]

if i dont destroy there will a lot clone left in scene then

[sour fulcrum]

the point of a pool is to re-use objects instead of destroying them

if you want to use a pool or not use a pool thats a whole different thing

but pools are built for not destroying

[kind skiff]

Disable the bullet so that it will not show

Then when you retrieve from the pool reset the velocity, position and direction of the bullet

[kind skiff]

Yess cause creating and destroying is expensive

[ivory bobcat]

With object pooling, the objects would simply be deactivated. Unless you're wanting to recollect memory (expensive and should not be done often), you're better off just leaving them disabled in the scene.

[kind skiff]

so we reuse them to make it efficient

[ivory bobcat]

Either way, the error was informing you that you've destroyed an object but you were still trying to use it somewhere..

[boreal sonnet]

ohhh okay thanks for that👍

yeah my fault

[kind skiff]

Well a good way of learning is through tutorial videos or ai. I find myself being able to learn very quickly and efficient from ai as it is able to provide me with examples of the implementation of the code.

Of course if you just ask it to generate everything for you without every reading and trying to understand the logic behind of it you will not be able to learn

[sour fulcrum]

its that time of the day where we gotta highly recommend that beginners should not use ai to learn nor should people suggest it

[ivory bobcat]

I would not recommend learning something from scratch with ai. It's okay if you're simply wanting to critic it's output or have it do tedious tasks though.

[kind skiff]

Why not though?

[sour fulcrum]

anyone curious can just search "ai" in this channel

make a conclusion however they want

[ivory bobcat]

It's very constructive in how it presents is suggestions/arguments and output but it's unaware of mistakes and flaws without curation.

[kind skiff]

I see people just generating and using the ai scripts

without understanding them

is that what you meant?

[sour fulcrum]

ai will lie to you and you won't know unless you know the topic <-> if you know the topic you don't need to use ai to learn

[kind skiff]

Yeahhh it makes mistake and flaws and most of the time not the most efficient way of solving the problems

[ivory bobcat]

And if the person is unaware of mistakes created by ai, the solution could be non functional or even completely wrong.

[kind skiff]

But I use it as a personal mentor that asks it to explain code for me

And of course I do not trust it so I always fact check

Whether the response from ai is correct or not

[sour fulcrum]

but then you could just skip the ai gaslighter and fact check directly lol, like everyone learning online for the past two decades

[kind skiff]

You can also ask it to cite sources where he get the conclusion or answer from

[kind skiff]

Owhh I see

[kind skiff]

Loll ok, well it's really a personal choice

[boreal sonnet]

well i'm learning from scratch through tutorials .. just trying to understand things

is it okay to befriend you guys ?

[ivory bobcat]

Are you using the builtin Unity object pool type or your own?

This is the object pool type created by Unity https://docs.unity3d.com/6000.3/Documentation/ScriptReference/Pool.ObjectPool_1.html

[boreal sonnet]

right now the builtin one....why is there any issues with that?

[kind skiff]

Sureee

[ivory bobcat]

Not that I'm aware of.

[boreal sonnet]

oh thanks

[brisk ibex]

I'm using an external editor to edit unity files. Currently I have to switch to vscode and regenerate the project files in order for the csproj files to update and my language server to pick up on new scripts. Is there any way I can automate this?

Is there any way I can roll my own "external editor" plugin/package?

I've noticed vscode and vs support seem to be built in packages or whatever the term is so that seems like a decent direction to check out but wanna check first.

[kind skiff]

I'm currently using jetbrains rider

[ivory bobcat]

Yours look similar to the older self made one that unity learn used to demonstrate in their tutorials
https://learn.unity.com/course/planning-for-top-performance-companion-toolkit/tutorial/introduction-to-object-pooling
Example excerp:cs GameObject bullet = ObjectPool.SharedInstance.GetPooledObject(); if (bullet != null) { bullet.transform.position = turret.transform.position; bullet.transform.rotation = turret.transform.rotation; bullet.SetActive(true); }

[brisk ibex]

not looking for a new editor haha, thanks tho

[midnight plover]

Did you set it as external tool in unity?

[brisk ibex]

I'm using a shell script as the external editor
(which manages neovim pipes to edit files)

I'm only using vscode to generate project file for LSP tooling

[ivory bobcat]

Where the newer builtin type would instead have you creating a script with the ObjectPool type and subscribing delegates etc

[brisk ibex]

ah https://github.com/apyra/nvim-unity

self answer I'll just look at this haha

[midnight plover]

😄 neovim, alrighty

[brisk ibex]

last time I used unity I hand rolled script for this, this is new and seems like exactly the direction i was going anyway haha

[midnight plover]

Coming from server or data scripting having a look into Unity meanwhile? 😉

[ivory bobcat]

The newer tutorial would be this one but it's at an intermediate level
https://learn.unity.com/tutorial/65df850fedbc2a082fb11029
@boreal sonnet

[brisk ibex]

no i just like fun editors lol

more of a general systems/general pl background

[boreal sonnet]

yeah it looks similar

[ivory bobcat]

You should be able to get a sample of the project as well if it's a bit overwhelming

Although you can create your own custom system to implement object pooling, there is a built-in ObjectPool class in Unity you can use to implement this pattern efficiently in your project (available in Unity 2021 LTS and onwards).

Let’s check out how to leverage the built-in object pooling system using the UnityEngine.Pool API with this sample project on the Unity Asset Store. Once you open the sample project, go to Assets＞7 Object Pool ＞Scripts ＞ ExampleUsage2021 for the files.

[midnight plover]

having all files open in one big chunk of tab overview? 😉 ah wait, I misinterpreted neo with the "default" vim 😄

[boreal sonnet]

ok i'll try this one

[brisk ibex]

neovim sucks atp honestly it's been recently inflated with younger users who seem to like a LOT of eye candy and uh "enterprise" APIs, I just can't live without LS support.

[brisk ibex]

hmm this smells like AI slop to me

Same approach I had via the edit pipe but it still doesn't support regenerating project files automatically?

Given the unity shipped plugin for VSCode seems manual this seems to be more of a unity thing ig?

How do you guys live like this? Surely spamming a button everytime a script is added isn't the usual workflow for an average vscode user? How else does the csproj get compile directives etc?

[midnight plover]

VSCode updates automatically, no need to "spam a button" 😄

[midnight plover]

Did you check out this here? https://dzfrias.dev/blog/neovim-unity-setup/

[brisk ibex]

Same issue still 🙂

I have that part down pat

I can double click scripts in unity and they pop up in neovim. working good.

My issue is specifically with the regenerate project files button spam

it seems whenever you add a script it needs to be added to some project metadata eg:

[midnight plover]

Ah my bad, just reread the article. Its exactly what you mentioned about regenerate buttoN 😄

[brisk ibex]

all good, it's a good point honestly I should explore around online for more setups in case someone has solved this lol

[midnight plover]

Only thing I do not understand. When I create a simple file outside unity without vscode open, it automatically triggers the reload inside Unity. But your issue is not unity not recognizing it but neovim missing the reference to the new script within the project scope?

[brisk ibex]

But your issue is not unity not recognizing it but neovim missing the reference to the new script within the project scope?
Yeah bang on,

Does your setup (whatever editor you're using atm) have a Assembly-CSharp.csproj in the root of the project dir?

with the <compile />s like above?

[midnight plover]

I am using vscode and yes, it does with itemgroup Compile and also None include, depending if its a package or not

[brisk ibex]

ooh https://spaceandtim.es/code/nvim_unity_setup/

given that's a "executeMethod" I could probably roll a really nice solution using an actual edit plugin like the github I linked above but maybe I can find a semantic to automatically detect when SyncSolution needs to be done.

This is what I'm doing atm btw, it's literally just a dash shell script which I'm setting as the external editor lol

[midnight plover]

Id say, whenever Unity reloads your scripts, it should sync it, cause also meta files have been created and Unity detected a "change"

[brisk ibex]

yeah that reload is seperate from the SyncSolution it seems

which is odd but I'm sure there is a reason why it's not triggered.

This is the setup for the above shell script for ctx

Doing unity work for uni atm haha

[midnight plover]

I mean, it works, but only manually. I guess, because other IDEs hooked into Unity will sync their own stuff, dunno 😄 https://docs.unity3d.com/ScriptReference/AssemblyReloadEvents.html is what I would be using with a simple editor script to just call it from reload and maybe also on save in neovim

[brisk ibex]

Or maybe on a similar note it doesn't regenerate project files because I created the script using a "browse" external editor and not one which supports generating the solution.

[midnight plover]

Hm, could be. I mean the external editor is just passing over the arguments of your script when double clicking it in inspector. Not sure what other args are coming form there.

You were talking about LS(P?) I guess. Maybe you have to restart that to get the latest state

[brisk ibex]

nah it's definitely the csproj generation.

I did some more research and it seems "more supported" external editors definitely call back into unity asking it to regenerate the project files via UnityEditor.SyncVS.SyncSolution so I guess that's definitely what I'll use.

I reckon I'm solid with that.

Thank you for the idea to search blog posts though, thats how i found that invocation ❤️

[chrome apex]

I have a stupid problem. I made a complex dual rig for my character, with a billion joints and a script and all that.

It works but I did it just for the right hand for testing. Now I have to do it for the left hand.

Is there a quick way to do this or am I manually adding everything here?

[midnight plover]

A billion joints, well in that case, you better write a script 😄

[chrome apex]

well yea, maybe

[midnight plover]

What is your problem exactly? I mean you can "easily" mirror copy joints by script.

[chrome apex]

well, I've never made an editor script before tbh. Do I just do foreach, and set rotation but flip the sign or something?

[midnight plover]

Try it out with a simple joint setup Id say. In the end the yes, you just need to flip the orientation based on the up/forward vector of the joint.

[lapis cedar]

hello

[chrome apex]

lmao I managed to do it all manually in an hour, cause there was other stuff to do as well

it even works

I'm also enticed to spend 10 hours programming and automating solution that would otherwise take 1 hour to do manually

[midnight plover]

dont tell me, a billion joints was overexegerated!? 😉

[chrome apex]

obviously

but each body part had one

and each finger had 3 (for index 1, 2 and 3 for example)

then I had to do and adjust colliders and script references, etc etc

[midnight plover]

yeh, standard bone rig. Most of the time you are faster doing it manually unless you would have to do it several times, than I would have written a script 😄

[chrome apex]

yeah, I'm glad I did it in an hour

Spending 10 hours on automating it vs an hour manually is just peak programming

people who do that are my spirit animals

[real thunder]

Are Unity build in pools objectively better in any way than just making a list of something yourself?

[real geyser]

hey, noob here, how do i make impossible geometry? something like this

[safe rose]

Hey everyone — quick question for anyone here who started in GDevelop before moving to Unity.

We’re a small indie studio and we prototype in GDevelop a lot. The problem we kept hitting was that when we wanted to move a project into Unity, we had to rebuild everything from scratch — which was brutal.

So we built a tool that converts GDevelop projects into Unity projects with generated C# scripts.

It recreates:
• Scenes
• Objects (as prefabs)
• Event logic (converted into readable C#)
• Basic physics & collisions

It’s rule-based conversion (not AI generated), and the output is a normal Unity project you can open and edit.

It’s not perfect — complex logic still needs cleanup — but it gives you a working starting point instead of a blank project.

Curious:
Would something like this have helped you when learning Unity?

Happy to answer questions about how it works.

[timber tide]

stencils. It's basically rendered in the same space, but because there's this mesh mask that changes the pixels to the other rendering if it aligns with the camera

[real geyser]

can make it so you can go through it? i watched some stuff but never found one that you can be in

[timber tide]

it's more of a visual thing, if you want to go through the space that's some extra logic going on

for one, a mask isn't volumetric. It's just a looking glass, but once you enter that area you need expand how that camera renders it. This can be tricky if you do want to use the same physical space.

[real geyser]

damn

[timber tide]

So, the stencil idea may not be ideal, but rather you use a render texture to project the image of another area and when you exceed the rendering* then you teleport the player to it.

[errant breach]

Hello ! Im making a SpaceShooter but im experiencing an issue.
If i go down and i touch a wall, i stop. Which is intented.
But if i go both down and left (for exemple) and touch a wall, i will also stop but i wont be able to go left again.

Do you know how i could fix it please ? Thank you !

[real geyser]

the texture is a plain tho, can there be seemles alternative?

my idea is like the room appears based on where the player is

is that ideal?

lik one way platform but in 3d kinda way

[timber tide]

it's a similar concept to how Portal does it if you do want to enter it

Two cameras, project the other camera's image when looking into it

[real geyser]

probably something with physics material wont know for sure because i cant see the code

[real thunder]

I wonder does Portal create duplicates of an object for physics?

when an object is partially on two sides

well, I guess u only need to duplicate a collider

[real geyser]

mm ok im gonna give it a go

[errant breach]

Ah, sorry 😅 this is a simple :
rb.linearVelocity = new Vector3(movementX, 0, movementY);

With movementX and movementY being value that get bigger and bigger to make smooth movement

[timber tide]

Lot of tutorials on it. It's relatively easy if you use first-person cameras compared to third

[real geyser]

what should i search for? i cant find any with physical impossible geomatry only visuals wit stencils

[timber tide]

It's not impossible geometry. It's just portal logic

Stencils allow you to store multiple different geometries in one space, but portals is different areas of rendering

[real geyser]

woah i thought this was something way more complex haha

just watched brackeys video on it

[timber tide]

If you enter the space -> teleport them to another area

[real geyser]

ok thanks 🙂

[hexed terrace]

A better way to do this would be a "portal" type setup, no?

nm, I see that's been suggested now

[keen dew]

You have to show the part that stops it when hitting a wall, or preferably the entire script

There is no code, it's just a BoxCollider that manage the collision with an invisible wall ! But okay ill send it !

[naive pawn]

perhaps a #1180170818983051344 would be more suited for this post?

also your file seems to be missing an extension.

[lunar axle]

so ive ran into a problem of unity editor loop really ruining the frame rate here, how can i fix the editor?

[errant breach]

Here's my code : https://paste.myst.rs/hre0xjpc
But i mostly think that the issue is related to the BoxCollider and the invisible wall

[real thunder]

ugh, profiling standalone build?

best I could do is to keep everything I can closed

like no active inspector

[lunar axle]

in my past prototype projects even in inspector the fps aint this bad. this is still a prototype project also.

so it shouldnt be this bad.

[silk scroll]

I've been seeing a lot of things saying to make your own timescale for time control, but how do you actually go about doing that?
I have a [SerializeField] public float enemyTimeScale = 1.0f; so far, and I'm simply multiplying Time.deltaTime by the enemyTimeScale in all the movement code.
Where do I go from here?

The movement is controlled by the new value but how do I get the rest of the script to abide by my timescale?

[real thunder]

...pretty sure you don't need [SerializeField] with public but it's unrelated

[silk scroll]

i definitely don't I'm just prototyping and my code's a little messy as a result

[real thunder]

well if multiplying by normal deltaTime by yours works you can multiply everything by it?

animator have some thing for custom timescale too iirc

also you should probably use Time.unscaledDeltaTime or how that was called

as a basis

in case you want to modify default one

also can you explain what do you mean by "time control" exactly?

[silk scroll]

The goal here is for the player to have a time freezing ability that affects everything but them.

[real thunder]

if it's just everything slowed down but player don't I would just modify Time.timeScale

[timber tide]

really not that complicated, you continuously check the custom timescale in update

[real thunder]

and make some changes for the player so it's not affected

[silk scroll]

so the player should be operating on a different timescale instead?
That might be simpler

But I did see a few things saying not to bother using Unity's built in timeScale to do things

[timber tide]

yeah, if you're trying to do a slow down mechanic where only one object is affected.

[silk scroll]

wait, if I multiply the regular timeScale by the player's own time scale that wouldn't work, because I'm setting unity's timeScale to 0

meaning the player's not gonna be doing anything still

[lunar axle]

try using Time.unscaledDeltaTime or u can calculate deltaTime in Update() or smth

[timber tide]

oh yeah than gotta use unscaled, otherwise just hook everything into your own set of timescale interfaces and not touch Unity's stuff

[humble bronze]

Dumb question but how much can i have happen on start before its a problem ?
is there a limit or can that one start frame take very very long? or would it crash ? i know i should only worry about optimising when it is problematic but i am curious

[timber tide]

well, ideally you don't want your program to become unresponsive, and considering gamers yell at the slightest hitch, you might want to make sure you're not instantiating too much at once, but not likely to be an issue until very later into your projects.

[humble bronze]

oke thank you

[chrome tide]

you can always just extend the initialization in a coroutine (do one thing at a frame, wait) and halt the update until you think the init is done.

[silk scroll]

The player still freezes using unscaledDeltaTime, then shoots forwards when time unfreezes. I think it's because I'm using a Rigidbody.

[timber tide]

that's probably a bit more complicated if you're using forces

I think you may be hardbound to using unity timescale methods

[silk scroll]

At the minute movement is handled by rb.MovePosition

[timber tide]

that should be fine then

[keen dew]

This is the wrong place but did you also add the package to the project?

[low copper]

Yes, it is installed/files present. What is the correct place?

[keen dew]

#💻┃unity-talk

[low copper]

ok. Thanks

[timber tide]

oh right fixed update might not even run at a timescale of 0. May just want to do your own scale multiplier

really I hate messing with unity time methods

[silk scroll]

Yeah I might stick to giving the enemies their own timescale to operate on.

I'm just not sure how to apply the multiplier to coroutines

[timber tide]

coroutines are just mini update loops

[chrome tide]

you could just do yield return new WaitForSeconds(t * timeScale) though that depends on your use of coroutines, bc i don't know if you can somehow extend a yield return null (maybe repeat it in a for loop ceiling the timescale to an int?)

[silk scroll]

If I multiply the WaitForSeconds that I have with my timeScale, that's going to make it wait for 0 seconds, since time is stopped

[chrome tide]

oh, right :P my bad. then maybe dividing instead of multiplying could work. and for the 0 seconds - you would need to check if the timeScale is equal to that and just halt the coroutine with yield return null until its value doesn't change. otherwise you'll get a division by zero error anyway

[silk scroll]

where would i place the timescale check and halt?

[chrome tide]

you'd need to check it before you do the t / timeScale calculation. e.g.:

while Mathf.Approximately(timeScale, 0f)
{
    yield return null;
}
yield return new WaitForSeconds(5f / timeScale);

just a simple code snippet, you may need to adjust it to your needs. best to use Mathf.Approximately() instead of == to avoid problems with floating point precision.

[real thunder]

are you sure you have to use approximately

[low copper]

I have a LoadScene() method in my SceneManager, that I want to to return a AsyncOperation if SceneManager is set to load async, else I want it to return true (or whatever...this side doesn't matter much). Any suggestions on how to handle the fact that I have to declare a return type that handles both branches?

[chrome tide]

i guess it would be easier to just do timeScale < 0.001f too :p

because a negative timeScale wouldn't make sense anyway

[real thunder]

would the world explode if timeScale was only tiny bit larget than zero?

[chrome tide]

idk, it depends on the precision in the / operation

[real thunder]

oh right, division

[rich adder]

Just always use the async version even if you don't end up using and do it synchronous

[real thunder]

yk what that would be fucked up anyway if you change your timescale
because wait for seconds being set only once and not updated once timescale changing

or am I wrong

[low copper]

I'm not really clear what you mean. Just initialize an AsyncOperation and return it even if it hasn't been assigned?

[rich adder]

public AsyncOperation LoadScene(string sceneName)
{
    return SceneManager.LoadSceneAsync(sceneName);
}```

[chrome tide]

you're talking about a scenario when the timeScale changes in the middle of the WaitForSeconds? yeh that would be kinda fucked but the seriousness of this problem depends on the context.

chromity decided to use coroutines so i just went with that in help context, but i think that a private float timer that she would constantly add Time.deltaTime to would be more precise, but that wouldn't work in coroutines context and would need to be called in Update. would work well with state machine i think

[low copper]

@rich adder But I don't want to load all scenes async. Sometimes I want to run SceneManager.LoadScene()

[real thunder]

yeah I think they would have to replace all enemy related coroutines with timers

[chrome tide]

yeh, though i don't know if it would be worth the struggle if it's not something extremely critical to how the enemies work. though it may surely look weird when they change the timescale and an enemy still works at a different one

[rich adder]

No reason to use sync version anyway , even if you don't end up using the returned / waiting the operation

[real thunder]

idk about you but I personally feel like coroutines are by default a hacky solution

[chrome tide]

i feel like they surely exist for a reason, though i dont use them really bc i'm addicted to state machines. i don't think they are certainly bad tho

[low copper]

@rich adder : I use synchronous loading when I need to know I have the scene available next frame

[real thunder]

they generate a bit of garbage and an internal timer every time you use them

something like that

[chrome tide]

the new WaitForSeconds may generate some garbage but that wouldn't be a problem in a game that uses coroutines wisely.

games are doing much more expensive stuff every frame.

[real thunder]

eh I guess

I use them for things happening rarely

however when I was starting out I went straight to generating dozens per second

then I got a tip to replace many coroutine events with a binary tree

mindblowing

[twin pivot]

        switch (attackType)
        {
            case GameStats.AttackType.Straight: attackRB2D.AddRelativeForceX(speed, ForceMode2D.Impulse);
                break;
        }
```It's not adding force relatively to the rotation, am i misunderstanding what ``AddRelativeForceX`` does?

[chrome tide]

i find coroutines useful when i need to extend a process into several frames and it acts more independent than other parts of my code. other than that, i don't use them that often.

[rich adder]

You can still use coroutine without ever touching waitforseconds. All you need is a while loop + time.deltaTime or time.unscaledDeltaTime. I do this often when I need self contained timers

[real thunder]

can I have an example

[chrome tide]

oh, you're right. so you probably do a while ... and just yield return null while the condition is true? or some other way?

[real thunder]

that's like... the same as using wait for seconds but without garbage? 🤨
no wait I think that calling a coroutine would generate garbage always
or main benefit for you is that it does timer logic but outside of your Update loop?

[silk scroll]

I can see this quickly becoming an issue with the coroutines since they're being used for my enemy's shooting at the minute

I'm gonna look into changing how the shooting is handled since enemies will be doing that
a lot

[chrome tide]

are you referencing to the timescale change mid waitforseconds?

[real thunder]

if it's tied to shooting you may use animation events

[silk scroll]

Yea that and some garbage too

[chrome tide]

in this case it would probably be best to use the timer thingy i discussed here -> #💻┃code-beginner message

[rich adder]

Yea

[twin pivot]

bump

[verbal dome]

It should add force relative to the rotation. What is happening instead?

[rich adder]

Im on metro so i get bad service rn. there will be a little garbage but imo a bit better than a new waitforseconds object if you have It in a while loop and has to change value each time as well . Update is good too but gets messy when you need multiple timer types. With corooutine I find it neater plus I have a generic one that r may invoke an action you can pass in the method .

The same coroutine can be called with different parameters and run independently, not true async but the similiar concept.
update loop gets tricky with that

[verbal dome]

What am i looking at? The projectile?

[twin pivot]

yes, it's supposed to shoot towards the nearest enemy

[verbal dome]

Are you perhaps adding the force before rotating the projectile?

[twin pivot]

ahh. I cant believe i missed that

[twin pivot]

apparently that wasnt the problem

[real thunder]

Oh, and it also support making coroutines waiting some time accounting for custom timescales
@silk scroll I guess that will work
using new internal timer inside a coroutine doing yield return null

[twin pivot]

    private IEnumerator SpawnAttack()
    {
        for (int i = 1; i <= attackLevel * attackPerLevel; i++)
        {
            GameObject _attackObject = Instantiate(_attackPrefab, gameObject.transform.position, gameObject.transform.rotation);
            RuneAttackPatterns attackBehavior = _attackObject.GetComponent<RuneAttackPatterns>();
            _attackObject.transform.LookAt(enemies[1].transform);
            attackBehavior.Attack(GameStats.AttackType.Straight, 1);
            yield return new WaitForSeconds(attackDelay);
        }
    }
```this is the code im using fire the projectile along with the previous code

[verbal dome]

I would not use LookAt in a 2D game like this. Set transform.right or transform.up to the direction towards the enemy instead

LookAt makes transform.forward face the look pos which is usually incorrect in 2D

Only thing keeping the rotation looking sane here is the rigidbody

[twin pivot]

i do want it to go towards the look pos

[wintry quarry]

yes but that's not the right way to set the rotation in 2D

[verbal dome]

The thing is that the "forward" vector in 2D is usually .right or .up of the transform

I suppose it's .right in your case as you were adding relative X force

[twin pivot]

ah thanks

[twin pivot]

what would be the right way?

[verbal dome]

var dirToTarget = enemies[1].transform.position - _attackObject.transform.position;
_attackObject.transform.right = dirToTarget;```

Basically "Make my right side face the enemy"

[wintry quarry]

this^ yeah

[twin pivot]

i see thanks

[wintry quarry]

it could be .up or .right depending on how your sprite is laid out

usually .right

[twin pivot]

i have it at (0,270,0) rotation cause LookAt was causing it look wonky otherwise lol

[wintry quarry]

btw is enemies[1].transform inentional? Why the magic [1] there?

[twin pivot]

that was from a sleep deprived session of coding where i just wanted a working prototype so i might have a lot of technical debt here

[real thunder]

worst part about it you don't remember your debt next day

or at least me those scenarios

[twin pivot]

im still having the same issues with it not being relative for some reason

[verbal dome]

In what method do you add the force?

If Awake then that's too early

[twin pivot]

attackBehavior.Attack(GameStats.AttackType.Straight, 1);
```right here

[verbal dome]

Only thing I can think of right now is that the rigidbody and transform rotation isn't synced yet at this point

[verbal dome]

@twin pivot Add this to the start of Attack method and tell me what it prints when you are facing upwards:

Debug.Log("RB angle: " + attackRB2D.rotation + ", transform z angle: " + attackRB2D.transform.eulerAngles.z + ", transform right: " + attackRB2D.transform.right);```

I edited it a bit

[twin pivot]

RB angle: 0, transform z angle: 117.114, transform right: (-0.46, 0.89, 0.00)
i'm guessing rb is desycned?

[verbal dome]

Is it always 0 at that point no matter where you face?

The angle

[twin pivot]

looks like it

[verbal dome]

Then yeah that tells us the rigidbody is not synced with transform

[copper hound]

hi, i ran into a bit of a problem, using NGO system whenever i try to go to next scene, the player/s isnt spawning in, what could be the fix here ?

[verbal dome]

@twin pivot Simplest fix, instead of AddRelativeForceX use AddForce(attackRB2D.transform.rotation * new Vector2(speed, 0), ForceMode2D.Impulse)

Another fix would be to set the projectile angle with rigidbody.rotation instead of using transform.

[verbal dome]

#1390346492019212368

[twin pivot]

It's working properly now, thanks for your help

[real thunder]

So I made a pool of bullets
it seems that despite I get a bullet out of the pool and teleport it at the barrel point at the same frame it renders on the old spot for some time
unless I set a transform position too
how does that works exactly?
I can't expect them to by synced?

I suspect that till new fixed update kicks in the rigidbody is on the old position?

[keen dew]

Setting the transform position is how you teleport things with a rigidbody. You don't need to touch the rigidbody position.

[wintry quarry]

rigidbody position doesn't get synced until the physics simulation unless you call SyncTransforms

[real thunder]

oh okay
in what cases I would need to use it anyway?

[swift crag]

This isn't correct; with interpolation enabled, the rigidbody will update the Transform every frame

which means your attempted move will be ignored

If you need the Transform to wind up in the right position instantly, then setting both positions will work, as will setting the Transform's position and then calling SyncTransforms

[swift crag]

the problem here is that the Transform is in the wrong place, not that the physics simulation is wrong

[wintry quarry]

right but setting the RB position won't set the xform pos

I was explaining the rendering issue

[swift crag]

oh, I see

I was reading that backwards

I'm so used to SyncTransforms being used to solve the opposite problem

I wonder how hard it'd be to make a little demo game that shows the various ways you can have problems with transforms and rigidbodies

You'd have to find a way to give a "slow motion" view of what would normally be single-frame or single-physics-tick discrepancies

[real thunder]

I use a script capable of changing framerate into terrible values and a script to change timescale for those purposes

to see if something goes wrong

last time I was making a game with a "teleport everything to 0 0 0 if too far" system
unpleasant

[swift crag]

That kind of thing is really handy

[verbal dome]

Can confirm that having a dedicated slow-mo button is great for debugging interpolation/rb/framerate related issues

[swift crag]

off-by-one-frame options are really easy to spot when the frames are big

I should add that to my game

I have the opposite: a mode that turns off all rendering and then cranks up the timescale to absurd values

it's useful for quickly "soak testing" the game to see if anything bad happens over time

[real thunder]

my side mouse buttons increase/decrease timescale inbetween values like 0.01 0.1 0.5 1 2 ect

[swift crag]

i do have slow motion, but it also adjusts the physics timestep

I'll try adding a "debug mode" slow motion that doesn't do that

this script is horrible
I like it

[cosmic quail]

i hate it 😔

[slender nymph]

you know you can just increment/decrement the index, use the % operator until it is within range, then just use that value instead of . . . that, right?

[real thunder]

originally there were more elses
can't send more without nitro

[real thunder]

I only knew that I was doing it wrong

yeah usually I increment decrement index... but then I clamp it with < 0 / > length
how would % helps?

[midnight tree]

If I see so much if's I automatically think "Hey why he didn't use the switch()?"

I dunno but mb in this case I think ehhh... its ok?

Its not ok BUT it looks like ok...

[slender nymph]

it will let you loop around the array instead of just stopping once it gets to an end. if that is the behavior you want then yes, use clamp instead

[midnight tree]

Ok now I see what you had to use switch() in Input.GetKey() methods

My fault

[real thunder]

I do use switch but rarely and I have to look up on syntax every time
this time it just started with 2 speeds and then ctrl c ctrl v go brrr

[midnight tree]

So maybe there is an error in if else logic... lol

Press F

[real thunder]

oh neat to know

...right, the advantage is that I don't have to store current timescale anywhere and don't need to interate through array to see what timescale value index is now

now script feels even more cursed

[slender nymph]

well what does it look like now

[real thunder]

I don't really have a motivation to change it since it work but sure hold up

public class TestGameSpeed : MonoBehaviour
{
    public float[] time_values;
    public int framerate = -1;
    public float gameSpeed = 1;
    public int picked_index = 3;
    void Start()
    {
        if (Application.isEditor)
        {
            Application.targetFrameRate = framerate;
            Time.timeScale = gameSpeed;
        }
    }
    void OnValidate()
    {
        Application.targetFrameRate = framerate;
        Time.timeScale = gameSpeed;
    }
    void OnApplicationQuit()
    {
        Application.targetFrameRate = -1;
        Time.timeScale = 1;
    }
    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Mouse4))
        {
            if(picked_index + 1 < time_values.Length)
            {
                picked_index++;
                Time.timeScale = time_values[picked_index];
            }
        }
        else if (Input.GetKeyDown(KeyCode.Mouse3))
        {
            if (picked_index - 1 >= 0)
            {
                picked_index--;
                Time.timeScale = time_values[picked_index];
            }
        }
    }
}

[slender nymph]

you've still got repeated code here that could be consolidated, but it's certainly better than it was

[real thunder]

what repeated code

[slender nymph]

you can consolidate the if statements to a single clamp call and the assignment to timeScale could be one line instead of two. your outer if statements really only need to handle incrementing/decrementing the index variable

although personally i would change it so that you've got a property that assigns to the timeScale in its setter

[swift crag]

so essentially

// change index, either up or down
// adjust timescale

(rather than repeating that logic for both the "increment" and "decrement" cases)

[slender nymph]

like this:

public class Whatever : MonoBehaviour
{
  private float[] _timeValues;
  private int _index;
  public int TimeIndex
  {
    get => _index;
    private set
    {
      if(_index == value)
        return;
      _index = Mathf.Clamp(value, 0, _timeValues.Length - 1);
      Time.timeScale = _timeValues[_index];
    }
  }

  private void Update()
  {
    if(Input.GetKeyDown(upKey))
      TimeIndex++;
    else if (Input.GetKeyDown(downKey))
      TimeIndex--;
  }
}

alternatively you could use a method rather than a property, but then you wouldn't be able to increment/decrement in place or you'd need another variable

[real thunder]

void Update()
    {
        if (Input.GetKeyDown(KeyCode.Mouse4))
        {
            ChangeTimeScaleInStep(picked_index++);
        }
        else if (Input.GetKeyDown(KeyCode.Mouse3))
        {
            ChangeTimeScaleInStep(picked_index--);
        }
    }
    void ChangeTimeScaleInStep(int step)
    {
        picked_index = Mathf.Clamp(step, 0, time_values.Length - 1);
        Time.timeScale = time_values[picked_index];
    }

like you expect something like that?

as I see yes

[slender nymph]

clamp returns the clamped value, it doesn't do it in place so you need to assign the result of Clamp back to something

[real thunder]

oh right, derp

[slender nymph]

also just FYI, but C# doesn't typically use snake_case, you should be using camelCase for non-public values and PascalCase for public ones (or camelCase for public fields per unity standards)

[real thunder]

I was always doing camelCase

but at some point I realized it's more comfortable to read snake_case

as a bonus it makes it easier to tell apart unity API from mine

[slender nymph]

well, just so long as you are consistent with it and are aware that it will probably be pointed out to you a lot when you ask for help

[real thunder]

yeah I see that this line - ChangeTimeScaleInStep(picked_index--); - also makes much sense....

I used ++ like it represent number and clamp like it's a method

oh boy I only now learn that there are ++i and i++ different operands

[tender mirage]

Honestly no clue what that achieves on compile but it sure doesn’t save me from weird delegate loop compile interactions.

[polar acorn]

++i will increment the value before returning it. i++ will return the value as it is, then increment it.

int i = 3;
Debug.Log(i); //prints 3
Debug.Log(i++); //prints 3, then changes i to 4
Debug.Log(++i); //changes i to 5, then prints 5

[frail hawk]

dont ask me where you´d use the preincrement

[tender mirage]

Thank you, i was really trying hard to think of something.

[real thunder]

@frail hawk here

doesn't work with postincrement

[polar acorn]

those are post-increment

[real thunder]

yes, this code doesn't work 😢

I had to replace with pre increment

[tender mirage]

I guess maybe in a enum? You can loop and wrap the value around. And if Enum.GetValues(oftype(MyEnum).Length is exceeded. You can wrap it back around to zero and you would use ++i for the value change

[slender nymph]

yeah but their code is actually wrong because of that

[polar acorn]

Ah, okay. Yeah, pre-increment looks like it makes sense for this, you want to change the number and then run the new one

[hushed sky]

which channel is there for help with unity problems?

[polar acorn]

Any of them. Whatever's closest to the subject of your question

[frail hawk]

you already posted it in the right channel

[hushed sky]

unity talk?

[frail hawk]

yes

[spark whale]

(i think this is the right place for me to post this?) For reference I don't know much about programming outside of a few months of C++ (not very useable in unity, I'm aware).
I'm following a tutorial for animating a sprite sheet for a top-down game, recreated the script from the video, IIRC it's for handling the animations alongside movement, but when I go to compile to test the game, I get the error code "The type or namespace name 'animator' could not be found (are you missing a using directive or an assembly reference?)".
I think I grasp the general idea of what it means (it can't link "animator" in the script to anything else, i think? I'm probably wrong), but I'm confused on how to fix itand what it fully means.
This is probably something very simple though.

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

public class playermovement : MonoBehaviour
{
    private float moveSpeed = 5f;
    private Rigidbody2D rb;
    private Vector2 moveInput;
    private Animator animator;

    // Start is called before the first frame update
    void Start()
    {
        rb = GetComponent<Rigidbody2D>();
        animator = GetComponent<animator>();

    }

    // Update is called once per frame
    void Update()
    {
        rb.velocity = moveInput * moveSpeed;
    }

    public void Move(InputAction.CallbackContext context)
    {
        animator.SetBool("iswalking", true);

        if (context.canceled)
        {
            animator.SetBool("iswalking", false);
            animator.SetFloat("lastinputx", moveInput.x);
            animator.SetFloat("lastinputy", moveInput.y);
        }
        moveInput = context.ReadValue<Vector2>();

        animator.SetFloat("inputx", moveInput.x);
        animator.SetFloat("inputy", moveInput.y);
    }
} ```

💡 IDE Configuration

If your IDE is not autocompleting code or underlining errors, please configure it.

Select one:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)
• VS Code
• JetBrains Rider
• :question: Other/None

[sour fulcrum]

your code has animator not Animator in the getcomponent

ideally your ide should be yelling at you about that

[spark whale]

but it isn't configured, I see

it completely left my mind that C# is case-sensitive, thank you, I'll work on configuring my IDE now

[stuck parrot]

can someone help me with my camera control script? I get an error and I cant figure out how to fix it

using UnityEngine.InputSystem;
public class CameraController : MonoBehaviour
{
    public float sensitivity = 100f;
    public float pitchClamp = 90f;
    private Vector2 lookInput;
    private float xRotation = 0f;
    private float yRotation = 0f;

    void Start()
    {
        Cursor.lockState = CursorLockMode.Locked;
    }


    public void OnLook(InputAction.CallbackContext context)
    {
        lookInput = context.ReadValue<Vector2>();
    }

    private float GetXRotation()
    {
        return xRotation;
    }

    void LateUpdate()
    {
        float mouseX = lookInput.x * sensitivity * Time.deltaTime;
        float mouseY = lookInput.y * sensitivity * Time.deltaTime;
        yRotation += mouseX xRotation -= mouseY;
        xRotation = Mathf.Clamp(xRotation, -pitchClamp, pitchClamp);
        transform.eulerAngles = new Vector3(xRotation, yRotation, 0f);
    }
} ```

in late update yRotation the xRotation variable is marked as an "expected error"

[sour fulcrum]

show the error

[stuck parrot]

says compiler error but I dont know what went wrong

[polar acorn]

You have two lines in the same line

Lines need to end in a ;

[stuck parrot]

god, how could I not see that 😭 😅

[polar acorn]

It's underlined in red

[cosmic dagger]

it's underlined where the error is at . . .

place that on a new line and you're good . . .

[stuck parrot]

yes I saw the underline but for some reason didnt notive the missing ;

[supple flume]

can someone explain how does insideUnitcircle work
the docs cover so lil about it

circle my bad not sphere

[frail hawk]

well it simply returns you a point inside a circle

[supple flume]

how is the circle position determined

[frail hawk]

imagine you have a circle and you want some random point on that

it doesnt have a position it simply returns you a vector2

could you tell us what you want to do maybe there is something you are missing

[frosty hound]

To be clear, it's not giving you a position within a circle from a given point

As in, not a point around say, your character.

[stuck parrot]

does anyone have experience in how to make a camera movement work. rotating the camera around the character uning mouse or right joystick? I have a look action in the input system that reads delta mouse or right stick as a vector 2 value but it doesnt seem to work

[hallow sun]

Input.GetAxis("Mouse X") is the simplest method imo

[stuck parrot]

isnt that the old input system? everyone is telling me to use the new input system

[frail hawk]

yeah but that would not rotate the cam around your object anyways

[hallow sun]

oops guess im old

[stuck parrot]

not what i meant 😄 im just learning unity for about a month now and didnt do coding in my life. all of the millions of different things are overwhelming and since i started learning the new input system i kinda try to ignore the old input method 😅

[frail hawk]

what kind of behaviour do you want exactly nuke

you want the cam to move around the player in a circle while always looking at it?

but with user input if i understood correctly

[stuck parrot]

soemthing like that for now: the code is very ducktapey since I looked up solutions from all over.. the clipping is still weird and the player doesnt take the cameras position in account so if i move forward it moves to the global x axis and not "away" from the camera

[supple flume]

yeah dw
i just ate hella food when i read about it and my brain was doomed
i understand it now

[stuck parrot]

i also dont know if its the right way but I couldnt get the camera to do all of it so i have a camera pivot (empty) as the players child which handels the rotation and the camera (pivots child) handels the collision using a raycast

[hallow sun]

The easiest fix for this is to rotate the player too and use transform.forward instead of Vector3.forward

[supple flume]

but what i need is
i want stuff to happen only on the edges of a circle
like this on the edges

[frail hawk]

you might want to open a thread for that nuke

[stuck parrot]

you wont believe me if I say i dont know what that is and how to do that 😅

im a compleete noob at discord and unity and coding too

[supple flume]

we all start somewhere
what matters is do we continue or no

[solar hill]

the thread

here

[frail hawk]

sorry i ment in the #1390346827005431951 these kind of threads dont get too much attention

[rough granite]

i would recommend using a chinemachine over coding the camera controlls yourself if you're still new to coding
though guess that's that my own opinion

[slender nymph]

then you don't want insideUnitCircle, perhaps check the documentation for the Random class to see if there is a more appropriate method to use

[supple flume]

doing that rn

[hallow sun]

seems like you want onUnitCircle instead of insideUnitCircle, idk ive never used it just googled it

[stuck parrot]

i dont know either methods so i tought coding would be the propper way to do it. and since i have to learn one anyways

[supple flume]

would recommend checking brackeys
he is the equivalent of Baghidad's library before burning down

[frail hawk]

you could have a List of Vector2 and then assign these manually

then simply random one element from the list

[supple flume]

this woul feel bricky and not smooth
