[fossil tree]

ok i gonna try that

tysm

have nice day

[gaunt ice]

no, your array is in forms of [][], you need to access it through arr[i][j]

[rich adder]

ObjectArray[index].Objects[somenidex]

[candid oyster]

thanks!

[rotund hull]

how can i transform then into grid points

or positions

[gaunt ice]

i forgot the first array is array of struct

[modest dust]

by knowing the background size

[rich adder]

[candid oyster]

Yay, its working

[modest dust]

If a background is 10x10 and at position (0,0) is the center of one of the backgrounds then at (0,5) you'd have two background touching each other. From (0,5) up to (0,15) is the second background and so on. Now do the math

[candid oyster]

Now I dont have to link up my 2d array individually with my game objects.

[turbid marsh]

Can anyone explain in clear language what this is? Main() in c#

[timber tide]

Entry point

[gaunt ice]

entry point to the program
but you wont see it in unity

[rotund hull]

alrightly i will try that in code

[modest dust]

To get the actual size of the background in world space look at pixels per unit in your texture import settings. If the background is 10 x 10 px and you have 100 px per unit then in world space your background is 0.1 x 0.1 units

[gaunt ice]

c# is case sensitive

[modest dust]

scratch best programming language

idk why even bother with unity

[polar acorn]

It's simple: Rigidbody exists. RigidBody does not. These are different words. Use the proper names for things

Then keep doing them until that is no longer the case

[modest dust]

good luck then

[rotund hull]

i have no idea how to code that

the idea

[modest dust]

[rotund hull]

[modest dust]

If your background is 1x1 unit and (0,0) is the center of the background with (0,0) coords then anything between position (-0,5 , -0.5) up to (0.5 , 0.5) is considered to be within the (0,0) coords
the background on the right with coords (1,0) would have it's center at (1,0) and anything within the range from (0.5 , -0.5) up to (1.5 , 0.5) would be considered to be within the (1,0) coords and so on

[next hound]

On Opening Visual Studio 2022 community version i get this error : StreamJsonRpc.ConnectionLostException:
The JSON-RPC connection with remote party was lost before the request could complete.

i just installed VS with workspace as unity and this happens...
Image

feel free to ping

[modest dust]

Basically FloorToInt((camPos + halfGridSize) / gridSize) = coords if I'm correct

If the grid size is 1 like in the example above and camPos is -0.4 on the x axis then you'd have a result of 0.1, resulting in 0
if the camPos is -0.6 on x axis then you'd get a -1 as a result and so on

[rich adder]

hard to say from this alone, did you use the Visual Studio Installer.

[next hound]

yes

[rich adder]

hmm

possibly Firewall issues

or your internet

[next hound]

hmm

[ivory bobcat]

Maybe try running visual studio as administrator

Else here's a discussion on it 2 years ago https://learn.microsoft.com/en-us/answers/questions/313193/could-not-start-visual-studio-due-to-an-error-stre

[green copper]

am I missing something obvious? I renamed the variable from m_thrust to thrustMain, and since that change all the force applications just stopped applying

changing the names back did not work the rigidbody just refuses to move

[frosty hound]

Check the inspector to make sure the values are assigned.

[green copper]

the particle emitters continue to turn on and off so the functions are definitely running

[frosty hound]

You shouldn't be giving default values to public fields in code, as it's overridden by the inspector.

[green copper]

Removed public keyword, function still does not apply force

[frosty hound]

Are there errors in your console when you run?

[swift crag]

An exception in the AddForce call would stop downThrustersOn() from running

I suspect the problem is coming from something else you changed at the same time.

[green copper]

No errors, two warnings but only in the VS console, not the unity one

[polar acorn]

No errors while running the game either?

[swift crag]

Can you share the rest of the script?

and yes, the important part would be while running

[modest dust]

Is the rigidbody kinematic or dynamic

[green copper]

yes, no errors while running

isKinematic is unchecked

copying the whole script, what's the tool to make it pastable?

[green copper]

I remember there's a tool I'm supposed to use

https://gdl.space/icejogonan.cpp

[swift crag]

your rigidbody doesn't happen to have a mass of a bajillion, does it

[green copper]

if relevant, the issue started happening when I renamed the thrust values, and hooked up the left and right thrusters to the function after I finished tweaking the size and placement

[swift crag]

i think the default is just 1

[swift crag]

stopped happening?

[green copper]

started

my bad

[swift crag]

ah

[green copper]

started happening/stopped working brain bug

mass is 50

but that's intentional and it was working before then

[polar acorn]

Log thrustMain before you call add force

[swift crag]

well, it's now private and is never assigned

so i am very confident in its value

[polar acorn]

It'd also show that the code is reaching Add force at all

[swift crag]

the thruster particles are working

unless all of the particle systems are incorrectly assigned or something, I guess

I would still go ahead and throw in a log

[swift crag]

when you eliminate the impossible, etc. etc.

[swift crag]

are you sure you aren't just flying into the floor or something

[green copper]

ship starts the scene in the middle of the space, gravity is lowered so there's a good few seconds in contact with nothing

none of the forces, linerar or torque, apply in that time

[swift crag]

your acceleration is going to be very small..

20 force on a 50kg object

i'd just set the force really big and see what happens

[green copper]

Gravity is one third

tried with 2000 and no effect

[swift crag]

okay, probably not that, then

Everything about your code looks like it should work fine.

[modest dust]

Did you try by editing the code back when it was public?

If so then that wouldn't change the value

[swift crag]

hopefully that meant "tried it just now with 2000"

[green copper]

I tried with 2000, then back to 20, then back to 2000 and it worked

?????

[swift crag]

did you actually recompile after changing the number

[green copper]

yes, both times

[next hound]

tried both
even with administrator
no luck

[green copper]

though humans are fallible yada yada but I'm fairly sure I compiled it

[next hound]

i checked firewall nothings on the block list

[swift crag]

Can you screenshot the inspector for the ship?

make sure to catch the entire rigidbody

[rich adder]

so when you click Launch ? you get error?

which one are you launching

[next hound]

yes

[next hound]

tried with both

[rich adder]

did you try this
#💻┃code-beginner message

particularly about the logs/reinstall

[swift crag]

How does it behave when using a huge force value? does it barely accelerate, or does it immediately smash into a wall?

I'm wondering if you had the wrong constraints

[green copper]

Possibly relevant, the gold blocks that represent the thrusters are rigibodies with mass 1 attached with fixed joints

[swift crag]

Which object is the joint component on?

[next hound]

lemme see what i can do

[green copper]

the thruster block so when I copied it it maintained the joint and I didn't need to recreate it

[swift crag]

I wonder if you were getting a bad interaction between the rigidbodies (through that fixed joint)

I've only used joints a few times before

[green copper]

with a thrust of 200f the ship has a thrust just barely too light to lift it, falls very slowly while thrusting at full

[swift crag]

that's an acceleration of around 4m/s^2

reasonably close to gravity at 1/3 strength

[green copper]

a thrust of 1000f is roughly how it performed before the issue

[swift crag]

you said that this happened after setting up the side thrusters. did this involve changing anything about the ship's setup?

I would deactivate those thruster objects see how it's behaving.

[green copper]

had the same thought and just finished test

no change

ship still requires 1000f thrust to mimic 20f from before

[swift crag]

that's a factor of 50. are you sure you didn't change anything about how you apply force to the ship?

because a factor of 50 is what you'd get if you switched from AddForce(..., ForceMode.Impulse) to AddForce(...)

the default physics timestep is 0.02, or 50Hz

50 is also the mass of the ship, conveniently

so you also could have previously been adding to the velocity instead of adding a force

or using ForceMode.Acceleration

[green copper]

The only things I did were rename the variables and add the side thruster particle emitters

I renamed the variables by right clicking them at the reclaration and using Visual Studio's "rename" feature

[swift crag]

a force of 20 newtons on a 50kg ship would never make it accelerate more than 0.4 m/s

which is very slow. not nearly enough to beat gravity.

[green copper]

the strange thing is, in the first testing

when every rigidbody was the same weight

the thrusters were too heavy and made the handling screwy and bottom-heavy

upping the mass fixed it

and I did have to up the thrust to compensate

but not to this degree

[swift crag]

and did you do that by changing m_Thrust in the inspector?

[green copper]

no, I did so in the script

[cosmic plover]

I'm watching and waiting. I want to ask a question but unsure if I should.

[swift crag]

just go ahead.

[green copper]

I used the inspector to refine it while running to find the right number, but to make the final change I stopped the simulation and edited the script and restarted it

[swift crag]

Editing the script would have had zero effect if it was a serialized field.

The field initializer's value gets clobbered when unity restores all of the serialized fields on the object.

[green copper]

So I was experiencing a wierd bug/mistake before that made things work, and that wierdness stopped working

[swift crag]

I feel like you just lost track of your values. Without version control, we can't really confirm what used to be there.

[cosmic plover]

I don't think this is a beginner question but I wanted to ask it here because it's pretty active. I want to edit multiple terrains through script without having a seam like you can in the editor with a brush.

So is there an easy way to do that?

[swift crag]

Yep. https://docs.unity3d.com/2023.2/Documentation/ScriptReference/TerrainTools.TerrainPaintUtility.html

It gathers data from one or more Terrains into a single texture

you can then paint on that texture

[cosmic plover]

I'd like to see an example of how to do this. I've tried it already and I didn't understand it.

[swift crag]

I have a (somewhat messy) example from a game I haven't worked on in a bit

https://gdl.space/adivaterib.cpp

I used Graphics.Blit to copy from the source texture to the destination texture. I think I modified a sample shader for that "Terrain Add" material

wait, that's not the right one.

oh, it was. i haven't touched this in a minute 😛

https://gdl.space/oxapiqudij.cs

This is all pretty old and messy. I'd rather find something else for you to look at.

[cosmic plover]

I can use the built in shaders though right? For set height or something like that?

[swift crag]

Yeah, I bet so

[cosmic plover]

The hidden ones

[swift crag]

I was using this to "stamp" the terrain with a texture

It draws on both the splatmap and the heightmap

[cosmic plover]

I just want to modify the height and then smooth it out.

[swift crag]

If you want to do multiple modifications, you'll need to "ping pong" between two different render textures

since you can't blit from a texture to itself

https://docs.unity3d.com/2023.2/Documentation/ScriptReference/TerrainTools.TerrainPaintTool_1.html

Ah, here's a little example.

Note that TerrainTools was in an experimental namespace in older versions of unity

but it should be largely the same

[oblique torrent]

is there a workaround to not being able to use System.Numerics BitOperations

im making a chess engine and my self written GetLSB function is soo much slower than BitOperations.TrailingZeroCount

[swift crag]

Why can't you use it?

too new?

ah, yeah, doesn't show up

[oblique torrent]

yeah

replacing my self written GetLSB and GetMSB increased speed by more than 200% 😪

[swift crag]

https://docs.unity3d.com/Packages/com.unity.burst@1.4/manual/docs/CSharpLanguageSupport_BurstIntrinsics.html

this may be helpful

you'd need to use these inside of Bursted code, I suspect

I think I messed with using these at one point

Looks like I didn't keep any code using them though

[oblique torrent]

hm

Unity.Mathematics has a tzcnt

hopefully its fast enough lol

[oblique torrent]

appreciate it

[charred spoke]

It should be

Im using it in my rendering code and it hasn’t been a problem

[swift crag]

I presume that it'd still be faster if you could Burst the mathematics calls

but see how it performs, yeah

I'm fuzzy on what goes on there.

[charred spoke]

You can burst anything from unity.mathematics

[oblique torrent]

idk what bursting is ill look into that later 🤣

havent even opened unity yet just been working in c# alone

[swift crag]

Burst lets Unity compile a subset of C# down to native code

gonna transfer it all later

so do i just burst compile certain parts of code

[BurstCompile] is magic

[ruby python]

Hi all, end of a long day and my brain is failing me.

Could someone help me out a little with this little piece of maths? 😦

  float hitDistance = hit.distance;
  hitDistance = -hitDistance;
  dustKickParticleRate = hitDistance * 335f;

Basically I have a raycast pointing straight down, as I hit the 'limit' of the ray I'm setting the particle rate of a vfx graph, what I'm trying to do is invert the distance number so that I can use the distance to drive the amount of particles emitted (lower the further away from the ground).

If that makes any kind of sense. lol.

[charred spoke]

static methods and anything that isnt a native object can be bursted

[swift crag]

so you want to divide by the distance

1 / x is very steep for x values near zero, though

[visual venture]

How do I input movement code?

[ruby python]

Yeah the distance goes between (roughly) 12 and 6.

[swift crag]

6 / distance would give you a value between 1 and 0.5

you could clamp this to keep it reasonable

[ruby python]

right okay, well I need to go between 0 and 2000 particles.

[swift crag]

you can do a few multiplications and divisions, or just use the lerp methods

[ruby python]

Sorry, honesly my brain has really given up on me now, been doing fluid simulations all day. Think I'm a bit math'ed out. lol.

[swift crag]

float t = Mathf.InverseLerp(nearDistance, farDistance, hitDistance); 
float rate = Mathf.Lerp(maxRate, 0, t);

this would be a linear interpolation instead of 1/x

[swift crag]

are you following a tutorial? lots of the stuff on !learn will involve getting movement input

[visual venture]

Yeah, I am, but my main problem is figuring out how to even open the code section.

[toxic cloak]

Is instantiating an object is better or seting it to active and inactive is normaly?

[swift crag]

I don't understand what that means.

[swift crag]

two different situations

If there's only going to be one copy of something, activating and deactivating it can make a lot of sense

like if there's a door that disappears after you find a key

Instantiation makes sense when you could have a varying number of something

you instantiate a bullet

[polar acorn]

In general, Instantiating something is going to be heavier than reactivating an old object. However, that old object is going to need to have various values reset in order to re-use, so you need to make sure you're properly setting that

The term for this is "Object Pooling"

[ruby python]

If you're going to be instantiating a lot, look at object pooling.

[toxic cloak]

i mean in my case i have a single coin in a single platform so which will be better instantiating or setting it to active

[polar acorn]

If it's just one thing, probably activating

[toxic cloak]

Yep Thanks All

Hi there, i was wondering how to change a variable in the middle of the same script? For example, i have a variable set to 5, that i want to be reduced by one every second. My main idea is this:

hey I'm getting this error and idk where it is in my code can someone point it out (I have no clue ab code)

[swift crag]

sounds like you need to configure your !ide

[eternal falcon]

We recommend using VS or Rider instead.

[swift crag]

that way, it'll highlight errors for you.

That looks like Visual Studio to me.

[visual venture]

By "the code section" I mean the area of Unity where the script for an object would be.

[polar acorn]

The inspector?

[swift crag]

If it says "Miscellaneous Files" in the top left corner, your code editor isn't set up properly.

[visual venture]

Maybe idk, it's my first day even with unity on my computer.

[polar acorn]

It'll be the panel that says "Inspector"

[swift crag]

If you have zero idea what's going on, then you should really be following a tutorial.

[swift crag]

ah, you are. which one?

[visual venture]

Oh I meant the one that looks like this. (Image from tutorial I'm watching)

[polar acorn]

That's visual studio

[swift crag]

that is the code editor.

notably, it is not part of Unity

[summer stump]

After configuring your ide, you may still miss this, because it will be a warning, not an error:

Don't put semicolons after if statements.

This is wrong:

if (something) ;

This is right:

if (something)
{
}

[visual venture]

Oh okay. I'ma watch the video more closely to figure out how they got there.

[swift crag]

The tutorial may not explicitly talk about how to install and use a code editor.

[visual venture]

Ah it was like this.

[wary sable]

how would you go about checking (by script) if an animator controller has a specific blend tree?

[swift crag]

This creates a new script asset. It has nothing to do with your code editor.

[fallen snow]

How do I configure my IDE?

[swift crag]

Follow the instructions in the bot message.

[fallen snow]

AHH thanks

[fallen snow]

oki

hi, how can i edit a toogle in the script like how i put a if for

like if the toogle is on that make a thing

sry im french its hard to explain xddd

[fallen snow]

I configured my IDE and it seems like it's working, I fixed an error

but now I have an warning

Idk what this means ngl I have no idea about code

[fossil tree]

man dw about warning

warning are normal

[fallen snow]

alright

[fossil tree]

if that run that good

XDD

[polar acorn]

You have an if statement with nothing in it, and you probably didn't intend to

[wary sable]

you have a semicolon after an if statment

nothing within your brackets will run with that there

[polar acorn]

This if statement has nothing in it. It does nothing at all

[fallen snow]

ok!

[swift crag]

; terminates a statement

[fossil tree]

so :(

[fallen snow]

yay fixed that

now I need to make it so it actually works

rather than crashing

[swift crag]

Toggle.isOn tells you if the toggle is checked or not

Assuming you are talking about the Unity UI toggle.

[fossil tree]

yes ty

[polar acorn]

Are you asking how to check the value of a UI Toggle?

Ah, Fen beat me to it

[fossil tree]

the thing i search is like the onclick of the event trigge

r

[timid prawn]

hey! Im new, can someone answer 1 question?

[polar acorn]

https://dontasktoask.com/

[swift crag]

that would be onValueChanged

[timid prawn]

ok x) mb, I found an interesting project on the internet that I wanted to explore to understand how it works a bit. I downloaded it as a Unity package, and everything was imported correctly, but the scene remains empty. I just wanted to know if this is normal. 😊

[summer stump]

That warning is what I told you earlier

Oh, you were told

[swift crag]

The package may include some scene assets.

search t:Scene in the Project window to show all scenes in the project

[fallen snow]

I'm trying to make it so that when this script is attrached to an object, upon collision it only hurts objects tagged with "Player" but rn it doesn't hurt anything at all. anyone can help? this is like reading another language ngl

[fossil tree]

yes i make search and find ty have nice day guy

[timid prawn]

ok I check!! thx a lot @swift crag sorry if my question seems idiot Im learning by myself

[polar acorn]

Why are you checking if this object is tagged "Player"? Wouldn't it make more sense to check the other object?

[fallen snow]

YES HOW DO I DO THAT?

that's what I'm trying to do

😭

[polar acorn]

Call compareTag on the other object

[fallen snow]

AA how

[polar acorn]

You have the collider of it as a parameter

Colliders have a .gameObject

[wary sable]

gameObject.ComparTag() refers to itself, just like using .this in plain c#

[fallen snow]

if (gameObject.CompareTag("Player")) so I swap compare tag to gameObject?

[wary sable]

when using OnTriggerEnter, the local var you create (in this case collisionData) is the refrence to the other object

so if you are trying to check to see if the other object is the player you will want to use that local var, not gameObject

[fallen snow]

I know very VERY little code I can barely understand

[wary sable]

all good, just remember that gameObject is referring to whatever game object the script is attached to

so if you have this script on a cube, calling gameObject will give you a refrence to said cube

[fallen snow]

so like if (gameObject.collisionData("Player")) is correct?

[buoyant knot]

no

[polar acorn]

gameObject.CompareTag("Player") is using this object's gameObject property. It is the same as writing this.gameObject.CompareTag("Player"). Collider2D also has a .gameObject just like this does

Use the collider instead of this

[wary sable]

no, you dont need to refrence gameObject at all here

[fallen snow]

I want to attach this script to enemy projectiles and I don't want it to hurt the enemy firing it

what is this

oh

[buoyant knot]

gameObject gives an object of type GameObject.
CompareTag is a method in the gameObject class. CompareTag takes a string as an argument (input).
When you call gameObject.CompareTag(“myString”), it calls this function. It compare’s gameObject’s tag with “myString” and returns true (if they are the same) or false if they are not.

[swift crag]

i think you need to slow down and follow some of the introductory scripting tutorials on !learn . you're writing some kinda weird code here

[eternal falcon]

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

[fallen snow]

I'mma try write in pseudocode

like
if (object colliding with is tagged "player")
{damage that object}

[buoyant knot]

before you write pseudocode, you must learn to actual code

[fallen snow]

my lecturer helped me with this when I originally did it, but it all got corrupted when my mum used my USB 😭

[polar acorn]

More like "If the collider I'm hitting's GameObject's Tag is 'Player'"

[fallen snow]

I have like no time to learn code I need to get this in 😭

[fallen snow]

YES YES

[timid prawn]

U had right, there is 4 t:scene! thx, Im trying to open them haha! @swift crag

[fallen snow]

samething in my head

that

how do I write that in C#

[wary sable]

so this is attached to a projectile, then you want to check if the thing its touching is the player correct?
Then you need to compare the tag "player" to the player object, not the bullet. gameObject.compare is checking the tag of the bullet not the player...

To refrence the object you are colliding with, you use the var you created in OnTriggerEnter(otherobject)
that "otherObject" is anything that enters the collider of the bullet. you want to compare the tag of that

[buoyant knot]

bro, you need to learn. we aren’t here to write code for you

[polar acorn]

The 's possessive in English is akin to C#'s .

So, you chain those together with . just like you do with 's in English

So, get the collider's gameObject's tag

[fallen snow]

so this is attached to a projectile, then you want to check if the thing its touching is the player correct?

Correct!

how do I make it so the bullet only activates the subtract health script if the collision is with an object tagged player?

[buoyant knot]

when you use left.right, the program looks in the class of left’s type for a method/field/property named by right

[timid prawn]

it's so hard to download a project damn

[wary sable]

how were you trying to check before?

[fallen snow]

basically before as long as it collided with something it modified the hp. but I want to make it so only on colliding with the player it does this, bc otherwise the enemy shoots itself when the projectile collider and their own collider merge

[wary sable]

yes, I get that but I'm asking how did you try and do it before... Im just trying to get you to think about this a little more in depth. (you were on the right track)

[fallen snow]

ok! I'll take an SC of the original script I am attempting to modify

[wary sable]

so how would you try and check if the object with a health script is the player?

[polar acorn]

So, notice how the first line has you calling GetComponent on the collider's gameObject.

[fallen snow]

Idk 😭 I want it so the modify health part only works if the object is player

[polar acorn]

So, how might you instead call CompareTag on the collider's gameObject

[fallen snow]

OHHH

[wary sable]

like what digi said, just trying to lead you back to that point; you were 90% correct out of the gate

[fallen snow]

I know it's just Idk how to write it bc I know nothing about coding 😭

where's the getcomponent part? 😭

[wary sable]

its in your sc

[fallen snow]

does it literally say GetComponent?

bc I'm blind and

yeah

[wary sable]

all good

[fallen snow]

OO PFOUND IT

[polar acorn]

Read the first line of your function

[fallen snow]

idk what to do now

[polar acorn]

Why did you change the get component

At no point did anyone say that should change

[wary sable]

so on that line you are storing the 'HealthSystemAttribute' of whatever object your bullet is colliding with as 'healthScript'. Notice that you get the 'HealthSystemAttribute' from a gameObject... That gameObject is whatever you collided with and its saved as 'colliderData'. using .CompareTag() how would you compare the tag of that colliderData?

[fallen snow]

I don't knoww :(

[polar acorn]

You need to realize that code isn't magic. All of the words in each line mean something as much as they do in the sentence you're reading right now

You already know how to call a function on an object

[polar acorn]

So now you need to call a different component

[fallen snow]

I don'ttt

I don'ttt

even

[swift crag]

yes you do. you've done it repeatedly.

[polar acorn]

you literally do

The very first line of your code

Is you calling GetComponent<HealthSystemAttribute>() on the collider's gameObject

[fallen snow]

I didn't write it! I'm trying to modify code from unity playground

[polar acorn]

But it's in your project

So you can read it

[fallen snow]

all I'm asking it how to get a working if statement bc I d k syntax.

like

this if statement does nothing

[polar acorn]

That is calling CompareTag on this object

is that what you want

[fallen snow]

no I want it to compare tag on the object it's colliding with

[swift crag]

then you'd better not call CompareTag on gameObject.

[wary sable]

ok, then what is the object that you are colliding with?

[fallen snow]

me! so this is a projectile that should attack me

so the enemy which tracks me fires at me

[polar acorn]

So then call CompareTag on that object

[fallen snow]

and this script is attached to the hostile projectile

[fallen snow]

HOW

[polar acorn]

the same way you are calling GetComponent on that object

[fallen snow]

I've been asking how to do that

I know that's what I've been trying to do

[polar acorn]

And I've told you how to do that in like ten different ways including pointing to your own code that does it

[fallen snow]

omg omg omg I literally can't understand you though

[swift crag]

your code already calls a method on the game object you're colliding with.

[polar acorn]

What is the first line of your collision function

[fallen snow]

calls a method?

[swift crag]

if you have literally no idea what any of these words mean then you really need to just learn properly. !learn

[fallen snow]

healthScript.ModifyHealth(healthChange);

do I put it in there

[polar acorn]

No, that's not the first line

What is the first line of the function

[fallen snow]

I was thrust into the deep end this is my first time working with C# and I'm forced to do this because my existing working scripts my lecturer gave me corrupted

[fallen snow]

I barely know what a function is in coding

[polar acorn]

Then go find out

[fallen snow]

Where's dilly he explained it easier 😭

[polar acorn]

because if you literally do not know what words mean how are we supposed to help

[swift crag]

that is my point. you shouldn't be trying to do this specific task when you don't know what any of the words mean yet.

[polar acorn]

#💻┃code-beginner message

[fallen snow]

I know I shouldnt!!! but I'm forced to 😭

this isn't a situation I should or want to be in

[polar acorn]

So, instead of sitting here repeating that you don't know what things mean, you could instead take that time to go find out

[swift crag]

sounds like you need to ask your lecturer for another copy of those files.

[polar acorn]

There's an intro to C# guide pinned in this channel

[fallen snow]

It is due in 4 hours

[fallen snow]

I did he didn't reply

[polar acorn]

Then you really don't have time to spare

[fallen snow]

not yet

[polar acorn]

best get crackin'

[fallen snow]

ok so

you guys know the solution pretty much

[polar acorn]

no we won't type it for you

[fallen snow]

not asking you to

just asking you to explain in a way

that's easier for a literal novice

[queen adder]

idk whats going on here but ask chatgpt ig

[fallen snow]

my adhd ass cannot communicate with you

[polar acorn]

This is a programming discord. Everyone here has ADHD

[fallen snow]

I cannot focus on what you're saying at all

[swift crag]

You know nothing about programming, so it's impossible to explain the solution to you without just giving you working code.

That's the problem.

You need at least a basic grasp of what these things mean

what it means when you see foo.bar.Baz() in a script

[fallen snow]

Hey I've come pretty far just by interpreting the code I'm attempting to modify

I get it in pseudocode not in C#

[ashen ferry]

comfort wtf is ur og discord tag

[polar acorn]

And I've literally just linked to the message where I told you how to translate pseudocode to C#

[fallen snow]

bruh

if you think that's translating pseudocode idk what to say

[polar acorn]

In english, you would say "Mandy's Wagon". In C# you would say Mandy.Wagon

You have the collider of the object you hit, it's a paremeter to your function

[fallen snow]

so like compareTag.collider

[polar acorn]

So, how would you get that collider's gameObject

[swift crag]

foo.bar tries to retrieve something named bar from a variable named foo.

[polar acorn]

That would be getting "compareTag's Collider"

Is that what you want

[wary sable]

  //how could you use theObjectThatHitMe??
}```

[fallen snow]

I want to get the bullet to initiate the modifyhealth action upon colliding with an object tagged as "player"

[polar acorn]

So, you want to check the tag of the Collider's GameObject

[fallen snow]

Collider.GameObject("Player")

but that's not mentioning a tag

[polar acorn]

You know that the function to check a tag is CompareTag

[wary sable]

to check something like that you need to call a method / function

[polar acorn]

So call that function on the collider's gameObject

[fallen snow]

If collider's gameobject's comparetag is ("player")

something like that?

[wary sable]

yes

[polar acorn]

yes, and you know how to do "possessives" in C#

[fallen snow]

collider.gameobject.comparetag("Player")

[polar acorn]

Okay, now instead of collider use the name you gave it in the function parameter

[fallen snow]

ok ok ok ok uhhh

what name did I give it

collider2d?

[wary sable]

you know the answer to the question I asked, just read through the statments

[polar acorn]

Check the code

You're already using the name in several places

including calling GetComponent on it

Or you can look up what a "Function Parameter" is

and see where you did that in your code

[polar acorn]

no

[wary sable]

what does the error say?

[fallen snow]

wait so colliderData.gameObject.CompareTag("player")?

0 errorsif I use that

[polar acorn]

That would be checking the tag of the colliderData's gameObject. Is that what you want?

[queen adder]

does anyone know how to transfer a project from desktop to a macbook

[golden ermine]

Why am I getting this error on line 53?

[rich adder]

Git

[fallen snow]

I think so!

[polar acorn]

You have cropped out the line numbers

[polar acorn]

Give it a spin and see

[golden ermine]

oh ahoot i didnt see haha

[queen adder]

oh good idea

[fallen snow]

IT WORKS

I need to test more

to make sure

[golden ermine]

here, why am i getting error on line 53

[fallen snow]

IT FLIPPING WOOOOOORKKSSSSS

[polar acorn]

OnShoot is null. Assuming it's a UnityObject, you can't use the ?. operator on them, they can be "null" without actually being null

It's kind of confusing but don't use those, use an actual == null instead

[short hazel]

Seems like it's a custom EventHandler, by the signature

[polar acorn]

Oh, actually, you're right technically it's all on line 53

So aimGunEndPointtransform could also be null

[golden ermine]

yea im following this guy

he did that and no error

[rich adder]

codemonkey code ?

[golden ermine]

yeah

[wintry quarry]

ugh why are tutorials teachng to use EventArgs in Unity 😦

[rich adder]

codemonkey has bad tuts although he says "its clean code"

[short hazel]

Because code monkey

[wintry quarry]

ah yeah codemonkey - that explains it

[polar acorn]

#💻┃code-beginner message

[short hazel]

Action<OnShootEventArgs>, the cleaner alternative since you never actually use the object sender parameter of an EventHandler

[wintry quarry]

If OnShootEventArgs is a class, not a struct, it's still not great

if it's a struct then fine

[golden ermine]

wait how, im getting error like this

[polar acorn]

That's not how you write an if statement

[short hazel]

hmmm

[uncut dune]

this piece of code somehow isnt working

[rich adder]

thats a big ass chain lol

[wintry quarry]

This is kinda cringe in Unity, just letting you know. it will work fine for the tutorial, but it's a lot of GC for no reason

[uncut dune]

indeed

[golden ermine]

yea ig but idk im just following tuto

[wintry quarry]

define "isn't working"

[rich adder]

start using the debugger lol

[wintry quarry]

you didn't need to change any of this

[polar acorn]

You want a != and also where's the rest of your line

[wintry quarry]

you only needed to figure out why aimGunEndPointTransform was null

[rich adder]

all you had to do was assign transform

[wintry quarry]

The ?. was completely fine for an event

put the code back how it was

and fix your null reference

[polar acorn]

Yes, I didn't know what type it was because you didn't show the full code

[uncut dune]

basically it checks if the enemy is worth more then the current currency available, and if it is less then the room it should start spawning from or more then the room it should stop spawning from and rolls another enemy if so

but now that I look at it

there is 2 conflictions

[wintry quarry]

but in what way was it not working

what was it actually doing

[golden ermine]

in code it finds that transform by a name

[wintry quarry]

that part is broken. focus on that part

[uncut dune]

all was working fine but some later enemies were spawning before they should

[rich adder]

I bet its using transform.Find

[uncut dune]

I think its this bc these 2 can never be true at the same time

[polar acorn]

Now that whole if statement isn't necessary, just get rid of it

[golden ermine]

yea

[wintry quarry]

my first recommendation is break that ugly line of code into something that a human being can understand

[polar acorn]

and find out why aimGunEndPointTransform is null

[rich adder]

that means the transform you find on, doesn't have child with that name

[rich adder]

god transform.Find is so ugly

CleanCode my butt

[short hazel]

Drag-drop. Direct reference

[uncut dune]

basically its a spawner script, the first part is if the enemy costs more then what is available, the second is have we reached the room it should start spawning from, and third is have we reached the room it should not spawn from

but those 2 last ones

are never true at the same time

[wintry quarry]

Yeah regardless of what kind of script it is and what it should be doing, you need to break that line of code into something understandable

[uncut dune]

maybe this will work

[short hazel]

CodeMonkey has the shitcode habit because it's lazy and fast to write. Still shitcode though

[uncut dune]

how

[wintry quarry]

use intermediate variables

[golden ermine]

like this?

[rich adder]

yes, do it for both

doing Find is ugly af

assign them inside inspector

[uncut dune]

ok thank will do

[rich adder]

preferably start using [SerializeField] private instead of public

[wintry quarry]

var randomEnemy = enemyPool[random];
int enemyRoom = randomEnemy.SpawnableFromRoom;
if (enemyRoom < RoomNumber || enemyRoom > RoomNumber)```

now the if statement is so much easier to read

it's very clear that if (enemyRoom < RoomNumber && enemyRoom > RoomNumber) is impossible
do note that it's quite possible for you to get an infinite loop with this though.

[golden ermine]

but that wont fix this on 54

[uncut dune]

there is actually 1 randomEnemy.SpawnableFromRoom and other randomEnemy.NotSpawnableFromRoom

they are different

[rich adder]

now u have to assign it

in the inspector

[golden ermine]

i did

[polar acorn]

Yes it will. Drag in the reference to aimGunEndPointTransform

[golden ermine]

do i still need this?

[uncut dune]

and I just figured I shouldve put || in all of them

[rich adder]

this is overwriting ur inspector..

i did say get rid of find

[wintry quarry]

ah see - this is what breaking the line of code down does - helps us notice these things

[uncut dune]

yah you are right, Im always scared if by adding these semi variables

I'll get less performance

Im only using them once

[golden ermine]

before removing those 2 lines it had an error, now when i removed it, it seems to work...thanks everyone

[wintry quarry]

nope. You have it backwards

[polar acorn]

Do you intend to make 4,000,000 of these every frame?

[wintry quarry]

doing that whole enemyPool[random].SpawnableFrom thing multiple times is the thing that's slower.

intermediate variables are never worse and are usually better performance wise

think of it this way: the variable exists whether you name it or not.

[uncut dune]

good to hear thank you

[uncut dune]

ohhh alright

[wintry quarry]

by naming it you get to reuse them and therefore avoid extra calculations

[uncut dune]

so its like calling a new variable everytime?

if I dont name them

[wintry quarry]

every time you write enemyPool[random]; it has to call the indexer function on the array

that's not free

it's faster to save it in a variable and reuse that variable. Local variables often don't even have to be written to memory

they can just live in CPU registers, which is the fastest thing possible basically

[uncut dune]

even if the random changes?

does it update?

or saves to the current random value

[wintry quarry]

no nothing updates

in this image you're using the same random twice though

random isn't changing

[arctic maple]

hi! currently trying to build our project game.
right now we have a main menu scene and a cutscene scene. when we load the cutscene scene, the entire game freezes for a moment and then nothing happens. no crash. no errors. this only happens with the cutscene scene. nothing visually changes either.
attaching a debugger gives no error message, and neither does player.log. the game otherwise works completely flawlessly in editor mode.
the last message in player.log says: [ALLOC_PROFILER] Peak usage frame count: [32.0 MB-64.0 MB]: 2943 frames Requested Block Size 16.0 MB Peak Block count 3 Peak Allocated memory 33.5 MB Peak Large allocation bytes 0 B [ALLOC_PROFILER_BUCKET] Large Block size 4.0 MB Used Block count 1 Peak Allocated bytes 76.4 KB ##utp:{"type":"MemoryLeaks","version":2,"phase":"Immediate","time":1697574917439,"processId":4928,"allocatedMemory":279875,"memoryLabels":[{"Default":-128},{"Thread":432},{"Manager":9506},{"GfxDevice":72},{"GfxThread":2112},{"Serialization":508},{"String":181},{"HashMap":1536},{"Utility":263624},{"PoolAlloc":112},{"VR":1696},{"Subsystems":96},{"CoreBusinessMetrics":128}]}
but i don't really know if it's relevant.
would appreciate any help i could get :]

[swift crag]

do the build settings include the cutscene in the scene list?

[wintry quarry]

when you attach the debugger and pause, you should see what the main thread is doing

[arctic maple]

i'll try that, thanks

[acoustic arch]

my colliders look weird when the player runs into them constantly

[uncut dune]

it is, look inside the while

[acoustic arch]

like glitching back and forth

[wintry quarry]

yes but that's inside the while

between the 3 array accesses it's the same

[acoustic arch]

should i change the movement to add force to the rigidbody insead of what it is currently, (Translating)

[uncut dune]

but I just want the while to stop when the random gets a valid number from inside it

[wintry quarry]

yes if you want collisions to work properly you cannot teleport your object around via the Tansform

[acoustic arch]

alright

[wintry quarry]

I know what you want to do, I'm talking about a performance and readability concern.

[uncut dune]

yah I'll try implementing it the best I can

[wintry quarry]

for example:

var enemy = enemyPool[random];
while (enemy.EnemyWorth > currentWalletSize || enemy.SpawnableFromRoom < RoomNumber || enemy.NotSpawnableFromRoom > RoomNumber) {
  random = Random.Range(0, enemyPool.Length);
  enemy = enemyPool[random];
}```

this only does enemyPool[random] once per loop iteration rather than 3 times

[uncut dune]

AAA that makes sense

[arctic maple]

is this the right place to look? tried a few times and not getting anything other than this or draw-something

[uncut dune]

ok I changed it

now I know my while loop is running

cuz its crashing unity

progress

[acoustic arch]

rb.AddForce(transform.right * moveSpeed * movement.x);

i tried this, it worked but the player slides and gets faster and faster

movement.x is horizontal input

[crude prawn]

does anyone know a workaround in this? im trying to make so the camera follows the player but only in the x axis

[arctic maple]

@wintry quarry this would be the other thing.

[polar acorn]

Store the position in a variable, change the X value of that variable, then set the position back to that modified variable

[wintry quarry]

you should see more than one thread 🤔

[wintry quarry]

ok that top one is promising

when you unpause and continue does it stay at that same location?

Or does it switch to other locations?

[wintry quarry]

var pos = transform.position;
pos.x = Player.transform.position.x;
transform.position = pos;```

[crude prawn]

Thank you

[wintry quarry]

you know you can do this without writing any code though right?

[crude prawn]

with cinemachine right

[violet topaz]

im trying to get the camera to follow the player but i dont know how to assign the player to the cam ```cs
public class CameraFollow : MonoBehaviour
{
[SerializeField] private Vector3 offset;
[SerializeField] private float damping;

public Transform target;

private Vector3 vel = Vector3.zero;


private void FixedUpdate()
{
    Vector3 targetPosition = target.position + offset;
    targetPosition.z = transform.position.z;

    transform.position = Vector3.SmoothDamp(transform.position, targetPosition, ref vel, damping);
}

}```

[arctic maple]

it just stays like that and actually ends up crashing after a while now
doesn't crash without a debugger connected either.
worth noting that the background audio is playing on loop the whole time.
what i'm doing is pressing a button that just loads another scene. that function works fine since other scences load without a hitch. just the cutscene scene that ends up doing nothing.

[wintry quarry]

Cinemachine is the best option but you can also do this very basic thing with a PositionConstraint or ParentConstraint

[wintry quarry]

you would need the script that spawns the player to assign it

[crude prawn]

would i be able to add a bit of delay though?

[wintry quarry]

public Transform playerPrefab; // assign in the inspector to the prefab
public CameraFollow camScript; // assign in the inspector to the object in the scene

void SpawnPlayer() {
  Transform playerInstance = Instantiate(playerPrefab);
  camScript.target = playerInstance;
}```
For example^

[wintry quarry]

with cinemachine yes

[crude prawn]

hmm ill give it another go

[heavy saddle]

Hi sorry I created the particles for the effect of the weapons that string of code I have to inseries to be able to give the input that every time I shoot it starts the effect

[wintry quarry]

you can use https://docs.unity3d.com/ScriptReference/ParticleSystem.Emit.html or https://docs.unity3d.com/ScriptReference/ParticleSystem.Play.html

[heavy saddle]

Thanks

[frank light]

        if (Input.GetButtonDown("Jump") && characterController.isGrounded)
        {
            characterController.velocity = new Vector3(characterController.velocity.x, jumpHeight, characterController.velocity.z);
        }
    }
}

the characterController.velocity gives me this, what am i doing wrong?

[swift crag]

You can't assign to it.

call Move() to move the controller

Move takes a distance and moves by that much

[green copper]

Is there an easy way to smooth this motion out?

[tough lagoon]

You are probably looking for Lerp

[swift crag]

You're moving by 0.5 meters every frame

That will be very fast

and also framerate-dependent

You should multiply that vector by Time.deltaTime so that you move at 0.5 meters per second, instead of 0.5 meters per frame

[green copper]

that smoothed it out a ton, thanks

[mossy arrow]

How do I fix this?

[swift crag]

you need to explain your problem.

i can guess what it is, but i've been wrong before (:

[mossy arrow]

ok so

the spawning is not in the right place idk why

it is spawning way to high or way to low

[swift crag]

okay, so i was wrong

i was guessing your problem was that you were going through walls

[mossy arrow]

mb

[swift crag]

The position of the object with PipeSpawnScript on it is going to be very important here.

since the script uses transform.position.y to compute where it's going to spawn the pipe

What is this component attached to?

[mossy arrow]

what component

the pipe?

this?

[swift crag]

No. The PipeSpawnScript component.

[mossy arrow]

I dont get it (im bad at coding)

[summer stump]

You are calculating the offset from the position of the object that has the PipeSpawnScript on it

So if that object is at -10 y ALREADY, that will throw off the offset

[rich adder]

also that pivot looks way off

[swift crag]

Somewhere in your scene is a PipeSpawnScript.

you attached it to a game object somewhere.

I want to see that object.

[swift crag]

Switch to the scene view.

Where is this object?

[swift crag]

press W so we can see some arrow gizmos

[rich adder]

might wanna fix this too

[swift crag]

that looks reasonable enough

Height Offset is set to 10, though

That looks like it'll be way more than one screen height's worth

Perhaps you need a smaller number.

[mossy arrow]

wait im so lost

what do i do rn?

[swift crag]

Change Height Offset to a small number.

See how it looks.

I think your height offset is way too large.

Do this in the inspector.

[mossy arrow]

5?

[mossy arrow]

ok

lets see

did not work

[swift crag]

Show me the inspector for the pipe spawner again.

[swift crag]

Okay. It looks pretty even now.

[swift crag]

The other problem is that the pipes aren't aligned correctly.

Notice how, in the prefab view, the gap between them isn't at the center?

It's above and to the right of the center.

[mossy arrow]

how do i fix that

[swift crag]

notice how the pipes are all at about the same height now. they're just too high on average.

[swift crag]

move them.

I don't know what the pipe prefab looks like

Does it have two sprite renderers for the two halves?

If so, move their objects.

[mossy arrow]

like this?

[swift crag]

surely you have moved objects around before

ah, you deleted the post

Show me the hierarchy window for this prefab.

I need to see every object.

[swift crag]

That is not the prefab.

I need to see the hierarchy window while you are editing the pipe prefab.

[mossy arrow]

this?

[rich adder]

you have to move the white ones where the circle was. Use move tool you'll see where it is

[swift crag]

That is not the hierarchy window.

Double click the Pipe prefab to start editing it.

Screenshot the hierarchy window.

[swift crag]

this is the hierarchy window, but you were not editing the Pipe prefab.

[mossy arrow]

this one?

[swift crag]

That is not the hierarchy window.

Do you not understand what the Hierarchy window is?

[mossy arrow]

nope

[swift crag]

It is the window named "Hierarchy". You sent me a screenshot of it a minute ago.

[swift crag]

It shows every object in the scene or in the prefab you're currently editing.

[mossy arrow]

this?

[swift crag]

Yes.

[formal escarp]

i have a question.

[swift crag]

Move Top Pipe and Bottom Pipe.

[formal escarp]

i have a project on unity, how do i make it so every time i press "R" the level restarts?

[swift crag]

when you click on "Pipe", that will select the prefab's root. That's where the prefab's "center" is.

Move the pipes so that the gap between them is around that center.

[swift crag]

If you are using the old input system (which is the default), you just need a component in the scene that does this

[mossy arrow]

wait so what do i do rn

[formal escarp]

the what

[swift crag]

void Update() {
  if (Input.GetKeyDown(KeyCode.R)) {
    SceneManager.LoadScene("someScene");
  }
}

note that SceneManager is in the UnityEngine.SceneManagement namespace. You will need to include using UnityEngine.SceneManagement; at the top of the script.

[mossy arrow]

so what do i do?

[formal escarp]

alrighty. thanks Fen.

you the goat.

[swift crag]

Exactly what I said to do. Move "Top Pipe" and "Bottom Pipe" so that the gap between them is at the center of the prefab.

The gap between them is not at the center right now

Click on "Pipe" and look where the arrows appear in the scene view. That's the center of the prefab.

[mossy arrow]

where do i move them

[swift crag]

I do not understand what is unclear about this.

Do not move them around in the hierarchy. Move them around in the scene view.

like, change their positions

[mossy arrow]

ohhhh

do i move down or up?

[swift crag]

Click on "Pipe".

Screenshot the scene view.

[summer stump]

See the circle?

[mossy arrow]

ye

[summer stump]

Move them there...

[swift crag]

Press W so that you can see some arrows instead of that tiny circle.

[mossy arrow]

w is not wokring

[swift crag]

Click the four-arrow button.

[mossy arrow]

done

now?

[rich adder]

scroll up

[summer stump]

That is not right

[rich adder]

still didn't click the 4 arrows

[swift crag]

you did not click the button. you are still in "Rect Tool" mode

please do what I ask you to

[rich adder]

https://docs.unity3d.com/Manual/PositioningGameObjects.html

bruh fr

[mossy arrow]

bro what W

i did press it

[rich adder]

just click it forget W just click it..

[swift crag]

I asked you to click on this button.

[swift crag]

Good.

You will now see arrows in the scene view.

[mossy arrow]

yes

[swift crag]

Click on Pipe. The arrows are the center of the prefab.

[rich adder]

did your teacher in school have to show you how to hold a pencil 😆

[swift crag]

Click on Top Pipe. Move it so that it's a little above where the arrows were.

Do the same thing with Bottom Pipe.

All of the pipes are appearing way too high because the center of the prefab is not where the gap is.

You need to move the gap to the center of the prefab.

[mossy arrow]

i do not see a

dot

[swift crag]

That's because the dot appeared when you were in "Rect Tool" mode.

You switched out of that mode.

[swift crag]

Assuming you currently have "Pipe" selected, this is correct.

They will now appear correctly.

[mossy arrow]

the dot is running away from me

what did i say

im trying to come to it

can someone help me?

[rich adder]

perhaps clarify whats wrong

[summer stump]

What does that even mean? What dot, and what does "running away from me" mean?

[mossy arrow]

wait it is sending

5s

[swift crag]

AH

See this?

Switch that from "Center" to "Pivot"

Center tries to put the arrows at the "center" of the object

this is often misleading

er, not local

from "center" to "pivot"

my bad

[mossy arrow]

i telled u it was running away from me

BRO IT IS RUNNING AWAY!

[swift crag]

whatever the rect tool is doing doesn't really matter

[mossy arrow]

how do i fix this!

[swift crag]

Ignore the rect tool. Leave it on "Move Tool".

[polar acorn]

What is the issue here

This seems to be doing exactly what is expected

[mossy arrow]

so what do i do

[swift crag]

ah, I had it stuck on "Center" mode (:

[swift crag]

.

[polar acorn]

do about what

[swift crag]

please do what i ask

[mossy arrow]

what mode do i pick

[lusty socket]

Hi im making a 2d sprite game and added code for an overhead checker, just wondering what to create in the scene to put this in and work

[swift crag]

pick "pivot".

[mossy arrow]

done

[lusty socket]

🙂

[swift crag]

now fix the positions of the pipes

you should see that the arrows now no longer between the two pipes.

[mossy arrow]

dont get mad but

the pipe is running away from me

[swift crag]

Select "Top Pipe".

[polar acorn]

What does this even mean

[swift crag]

If you select "Pipe", you will be moving the entire prefab around.

[mossy arrow]

do i move one at a time?

[swift crag]

You can select both at once if you want to.

[hexed terrace]

Why is so much space being taken up in here with non-code basic beginner stuff

[swift crag]

yes, I was just typing that, actually

[hexed terrace]

-> thread

[swift crag]

this is not remotely a code problem and we should've moved it a long time ago

@mossy arrow if you have any further questions, please post in #💻┃unity-talk .

[swift crag]

"overhead checker"?

[hexed terrace]

Please create a thread in #💻┃unity-talk 😄

[mossy arrow]

but someone said to go here

[swift crag]

Doesn't matter.

This is no longer a code problem.

Please make a thread in #💻┃unity-talk .

[lusty socket]

yes so when im crouching before i stand back up itll check if any obstacles are in the way

[swift crag]

ah, right

I would use Physics2D.CheckBox to test if there's anything above the player.

wait, wrong name...

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

2D and 3D are just different enough to trip you up

This method will check if there is a collider inside the box.

If you set the layer mask to only include the level's layer, then the query will ignore everything that isn't the level.

perhaps...

Collider2D hit = Physics2D.OverlapBox(player.transform.position, Vector2.one * 0.2f, 0, LayerMask.GetMask("Level");

bool canUncrouch = hit != null;

This is probably not the correct point to check, though.

it'll probably be at your feet.

I'd add an empty object to the player where you want the "head check" to be centered at

then just use its position.

Maybe like this.

This is basically identical to a "ground check".

[lusty socket]

@swift crag Could you check my code please im getting the error Parameter Crouch does not exist after completing my code for the crouch and ive no idea why. thankyou

[swift crag]

if you show me your code, perhaps!

[lusty socket]

whats the website to create a code url sorry?

[swift crag]

            rb.velocity = new Vector3(0, 10, 0);
        }
    }
}

can anyone see what i am doing wrong with the jumping part of this script, it doesn't do anything.

[crystal cipher]

I made a daily reward system

[polar acorn]

You appear to have a CharacterController and a Rigidbody on the same object

Don't.

[timber tide]

Smells of gpt

[polar acorn]

Is this a question

[frank light]

so would it better to do movement through rigidbody or charactercontroller?

[swift crag]

this is very weird

[lusty socket]

https://gdl.space/apamibeyot.cs

[polar acorn]

There is no "better". Both do some things easier and some things harder than the other

[swift crag]

Use a CharacterController if you want to directly control movement.
Use Rigidbody if you want the player to be affected by other physics objects.

[frank light]

sorry for asking a question in a help channnel Fen

[swift crag]

Of course, you can also just use a kinematic Rigidbody if you really want.

It's fine to make mistakes. I'm just commenting that it's an unusual setup.

[polar acorn]

That's not the thing that was called "weird"

it's the attempting to have two different movement controllers

[swift crag]

CharacterController is used for non-physical movement. All it does is make sure that you don't go through walls.

[timber tide]

rigidbody-light

[lusty socket]

@swift crag this isnt all the code its just what has been added to make the crouch if you need any thing else just ask

[polar acorn]

Do you have an animator parameter "Crouch"

[lusty socket]

ohhhh no i completewly forgot to do that. thankyou sorry i was just being extremely dumb

[swift crag]

zap

You won't get a compile error becauase C# has no idea about which animator parameters do and don't exist

As long as you pass a string, it's happy

[livid jacinth]

ok i was asking about it yesterday but this is still bothering me, I have a prefab with a script that has an array on it, when I try to change the size of the array using the inspector, the array disappears completely and I'm getting this wall of text pop up in the console. Nothing sticks out to me as the cause for it to happen, can someone take a look to see if you can figure it out?

https://pastebin.com/NHzkZwkz

[swift crag]

i'm randomly getting that too

i have a lot of nested lists in my inspector

what unity version?

I am on 2022.3.10f1 at the moment (the 2022 LTS)

[livid jacinth]

I was on that one, then I updated to 2022.3.11f1 and it's still happening

[swift crag]

I mostly just get error spam when any non-transform component is being inspected

in a way that doesn't make stuff actually disappear from the inspector

[livid jacinth]

It was working perfectly fine until I tried to see if I could have nested arrays in the script and that's when it blew up

[swift crag]

but I have definitely seen that one a few times..

[livid jacinth]

yeah i've noticed if I click off the prefab and then go back to it, the array is still there and fine

It would just be nice for it to not throw a fit when I want to do it the convenient way

[swift crag]

I have had some trouble cross-referencing the error with the code that unity publishes

https://github.com/Unity-Technologies/UnityCsReference/blob/master/Editor/Mono/SerializedProperty.bindings.cs

all of the versions in the changelog are alpha versions

[livid jacinth]

if i try to click on any of the scripts in the error it just comes up with nothing

[swift crag]

yeah, because the actual source isn't on your disk

[livid jacinth]

oooooh

[wary sable]

what is the difference between behaviors and effective behaviors?
(in ref to: GetBehaviours() & GetStateEffectiveBehaviours() )
https://docs.unity3d.com/ScriptReference/Animations.AnimatorController

[swift crag]

It looks like you can override the behaviours that are used by individual states.

notice how you can add behaviours to the layers

not just the individual states

[wary sable]

ahhh

thank you!

[swift crag]

ah, but that's not quite it

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

https://docs.unity3d.com/ScriptReference/Animations.AnimatorControllerLayer.SetOverrideBehaviours.html

You can override behaviours (and motions) for a specific state

[valid finch]

I thought entering Playmode reset everything in your program.. like hitting the power switch for a game. I have some stuff that is being stored with don't destroy on load.. and It is persisting.. How the hell do I reset my scene to the default??

[swift crag]

So if you overrode the behaviours for a specific state, the "Effective" method would give you the override

not the state's original behaviours

[wary sable]

ok, that makes a lot more sense. Not really useful for what I'm trying to do but good to have an answer.

Thanks 😄

[swift crag]

(so this was unrelated)

[valid finch]

Is there a way to reset everything in your scene within unity? I always thought exiting playmode reset everything to default values and positions. Weird

[swift crag]

It generally should, unless you're doing some Bad Stuff

I think instantiating inside OnDestroy is "bad stuff"

I think you'll get a console warning if you do that

[valid finch]

Alright.. yeah. That was weird.. it was keeping the xValue I was storing.. even after closing

[lusty socket]

Can anyone tell me place to go to ask for help with animations in unity?

[valid finch]

#🏃┃animation

[swift crag]

Were you doing that?

[lusty socket]

Can anyone help with my crouching, assuming its a coding issue as the speed isnt slowed down when pressing c and the animation doesnt play either, i dont know what you would want to see for help so ive attatched my code below, thanks

https://gdl.space/asucaduyez.cs

[swift crag]

use Debug.Log to check if your code is running at all

[lusty socket]

the running and jumping are all working, just the crouching

[swift crag]

Cool. But how do you know your crouching code is even running?

[swift crag]

Do this.

[lusty socket]

its justplaying the debug the entire time not just when pressing c

[swift crag]

I don't know what you did, so I can't really tell you anything.

I did notice, though, that crouchPressed is never set anywhere in your code

[lusty socket]

what can i tell you to help out just to give you a better idea
