i have good idea learn assembly first

[shell sorrel]

stop saying words

[timid ember]

oops

i read a line of assembly code and i could barely watch without throwing up

[shell sorrel]

also assembly is vauge

like assembly for a x86 vs for a old console, or for a arm or risc is entirely different complexity and instruction set wise

[devout flume]

Assembly isn't that hard

[timid ember]

blocked

[devout flume]

I mean it's just a few flags, some registers and instructions that do things 😂

[shell sorrel]

its more work but spec wise there is much less to learn then say C#

[wintry quarry]

The universe is only made of a few elementary particles. How complicated could it be?

[shell sorrel]

also there is no point since all it does is creates lots and lots of work

and then if you want to target a other platform you have to write yet more of it

also a good compiler will output more optmized code then you will write in asm

[devout flume]

Yes of course, you have a set of elementary stuff that lets you do a lot of things 😂

Reading it without comments is awful tho

[timid ember]

i am still confused, why did it work for the tutorial?

is it an older unity ver?

[hexed terrace]

if it works in the tutorial and not for you, you missed something, did something wrong, or haven't gotten to a part where it works yet.

[shell sorrel]

also would remove the try catch infavor of doing a double.TryParse

that way you can properly handle both outcomes of the parse and not mask other potential errors

Also ButtonTap is never called and everything is public which makes it harder to tell what parts are supposed to be purely handled in this logic vs called from elsewhere

[arctic arch]

What does unity consider as "Long life code"?

[shell sorrel]

will need context for that question

[arctic arch]

At their last announcement thing they said they want to increase compilation speed by not compiling the core and "Long life code" so Im asking what they would refer to with that

[shell sorrel]

ah

[ruby python]

I'm having a silly maths problem.

I have a value range of 14 - 100 but I need those values to be 'remapped' to 0-100. How can I do that?

[shell sorrel]

so what that means is say you have a library full of tools you added at the start of the project and very rarely modify

those will not be recompiled when other thigns change

[arctic arch]

So any dll/lib file I import then?

[shell sorrel]

nah dlls never get recompiled since that was manually done before hand

this is for AssemblyDefinations

so ones you define yourself or code in packages etc

[arctic arch]

So kinda like #pragma once in cpp?

[shell sorrel]

little smarter then that but similar idea

[arctic arch]

okay thanks

[shell sorrel]

like for example in my project i have a NPC behaviour editor i made

i made it over a year ago and it rarely every gets modified, but is a ton of code

in the new unity because i have that in its own AsmDef it would not recompile that assembly becuase i changed other code

[burnt vapor]

That's not the AI fault

This is the issue with copying code in general

You have no idea what it does if you never wrote it, and as a beginner you can't read it either

hey guys im having an issue where its returning error because the nameText variable is null, any ideas? this is the object structure https://gdl.space/bulasehapa.cs

wait nvm turns out i needed to use TMP_Text instead of UGUI

[wintry quarry]

yeah you're using the 3D world space text version

TMP_Text works for both

[rancid tinsel]

that makes sense

[nocturne kayak]

quickie here

what's the difference between | and ||?

let's say, i want to check if variable fruit is apple or orange

[night raptor]

then you use two

[shell sorrel]

one is bitwise or the other os boolean or

[nocturne kayak]

and if it's either apple or orange, return true

[shell sorrel]

use || for booleans

[night raptor]

Very rarely you need to do bitwise operations and if you don't even know what they mean, you should stick to ||

[shell sorrel]

| still works on bool, but its short circuit logic differs would 90% use || unless its like bitwise logic on a enum

[nocturne kayak]

So this:

if (axisHandler = xAxisHandler || axisHandler = zAxisHandler){

 }

reads alright?

[night raptor]

two equal signs...

[nocturne kayak]

oh shit

[ivory bobcat]

The docs for reference https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/boolean-logical-operators#logical-or-operator-

[nocturne kayak]

yeah

[shell sorrel]

also same for & and &&

would use the && for all boolean stuff

[night raptor]

In some cases using bitwise for booleans may make sense (when you want to execute both sides regardless) but even then it would be bad for readability and therefore using a different solution would be highly suggested

[shell sorrel]

in that case i would still rather execute both, get the returns then do the condition

much more clear intent

[night raptor]

Yeah, not good for readability

[shell sorrel]

i have only used those operators for bitwise stuff

which does come up a decent amount of time

[night raptor]

same

[ivory bobcat]

Assuming you aren't doing any bit operations, they would behave like..
Logical OR (|):

The | operator computes the logical OR of its operands. The result of x | y is true if either x or y evaluates to true. Otherwise, the result is false.
The | operator always evaluates both operands. When the left-hand operand evaluates to true, the operation result is true regardless of the value of the right-hand operand. However, even then, the right-hand operand is evaluated.
Conditional Logical OR (||):
The conditional logical OR operator ||, also known as the "short-circuiting" logical OR operator, computes the logical OR of its operands. The result of x || y is true if either x or y evaluates to true. Otherwise, the result is false. If x evaluates to true, y isn't evaluated.

[nocturne kayak]

That's a bit of a better explanation, thank you

I'm sure there's a case for it, but i can't picture it right now

why would i ever need to do a bit operation within unity?

[shell sorrel]

flag enums

GizmoType.Selected | GizmoType.Active | GizmoType.NonSelected gives me a enum value that has all 3 of these bits set

var isSelected = (gizmoType & (GizmoType.Selected | GizmoType.Active)) != 0;
on the flip side this is true, if either of these bits is set

[polar acorn]

Try locking a Rigidbody's rotation on X and Z in code without it

[shell sorrel]

keep in mind not all enums do this, only enums meant to be used as flag enums, where there are not overlapping bits betwene values

can do the same on any int type as well (byte, sbyte, int, uint, long, ulong, etc)

[verbal dome]

Mathf.InverseLerp + Lerp

[shell sorrel]

yeah InverseLerp will get you to 0 to 1 range

[ruby python]

Yeah I got it sorted, thank you 🙂

[shell sorrel]

then lerp can go from 0 to 1 to any range you want

[nocturne kayak]

So, something a bit more specific

This is really close to the behavior i want

But instead of dragging the cube, i should be dragging the handle, i moved the code to the cube itself

https://hastebin.com/share/datukazufo.csharp

this is the code btw

My initial thought on how to fix this is to try and calculate the distance between the handler and the cube at first frame

and offset that at update if it's being dragged

[timid ember]

went through thrice, I have written stuff ditto right and code isn't placed wrong

[nocturne kayak]

but i'm not entirely sure that's the best approach

[polar acorn]

What isn't working about it, what's the code, and what's the tutorial

[shell sorrel]

what is calling the code

the code you posted just as it as a public method and nothing in that script ever calls it from a message like awake or update so must be called externally

[verbal dome]

That should fix it though

[zenith cypress]

^ Cache offset on mouse down, add that offset to your final position, profit

[timid ember]

making a simple calculator using unity on YouTube by GAW

[timid ember]

all the buttons 0-9 and operators

[polar acorn]

Okay, and the first two bits of information I asked for?

[shell sorrel]

so break thigns down, add breakpoints or logs and find the exact flow

also get rid of that try/catch its just going to hide issues

[timid ember]

with try and catch, the code gives invalid at every inputs

when I remove it, gives the error "cannot convert dbnull into double"

[livid gale]

Hello. I'm trying to set up an interface for a sprinting action in my project but the coroutines I established seem to be resetting the value instead of gradually increasing and reducing the stamina value according to the conditions I set.

Link is here:

https://hastebin.com/share/haqirolimo.csharp

[timid ember]

yes I caught on that I have remove it

[shell sorrel]

yes, do like a if (double.TryParse(mystring, out var myNumber)) { instead

[timid ember]

i have kept the result as a double 0.0, changes to my values

do you mean inputfield I use as string?

[shell sorrel]

at the point you are trying to parse a string into a double

[timid ember]

ok so the input

[polar acorn]

You're starting a coroutine inside a while loop. That means you're going to start infinity coroutines until your stamina hits zero, then all of the coroutines you started will stop

[shell sorrel]

if you use the TryParse instead of getting a exception on failure, you can just branch in a if statement.
the try/catch is very bad since its a very broad exception you are checking for, so if literally anything goes wrong it will do the catch, even if unrelated. that will hide error logs

[polar acorn]

Each instance of the DecreaseStamina coroutine is going to hit a single subtract call before hitting their yield, and that's the only reason this code doesn't crash unity

[livid gale]

Well. How can I keep decrease stamina active while the button left shift is held?

[polar acorn]

Probably by checking if left shift is held in Update, and subtracting some small amount of stamina each frame

[shell sorrel]

first detect input, and if its held down, then on all frames its held down decrease stamina, would also scale it by delta time so its not depednent on the framerate

[livid gale]

I have put the Running() method in update

[polar acorn]

Remember, a while loop runs to completion. Once a while loop starts, nothing else in the entire program can occur until it finishes. The yield in a coroutine "pauses" the loop for a moment, but Running is not a coroutine. That while loop is going to do absolutely nothing else in the entire program until stamina is 0

No new frames can render. No objects can visually change. No other objects can run any code at all

until Stamina hits 0

[timid ember]

why is tryparse hiding erro

error

[shell sorrel]

its not, the Try/Catch is that you were using

[timid ember]

 public void ans()
    {
        if (double.TryParse(CurInput, out answer))
        {
        answer= System.Convert.ToDouble(new System.Data.DataTable().Compute(CurInput,""));
        CurInput=answer.ToString();
        UpdateDisplay();
        }
        else
        {
            CurInput="invalid";
            UpdateDisplay();
        }
    }
    public void Clear()
    {
        CurInput="";
        answer=0.0;
        UpdateDisplay();
    }
    public void UpdateDisplay()
    {
        disptext.text = CurInput;
    }
}

printed invalid on 9+1(i may or may not have used in incorrectly)

[shell sorrel]

also you are not even trying to undertstand things, you no longer need the System.Convert.ToDouble since the double.TryParse does it for you

[polar acorn]

If CurInput is something that can be parsed in a double, it'll do the first chunk. Otherwise, it'll set CurInput to "invalid" and update the display. For what it's worth, the word "invalid" is also not a valid double

[polar acorn]

Is CurInput the string "9+1" because that's not a double and it is properly reporting it as invalid

[fervent abyss]

i have an Array with a non specified size. If i do myNoSizeArray = otherArray, its going to copy size and the data, right?

[livid gale]

What commands can I use to subtract variables by frame?

[verbal dome]

No, if you do that then both array variables are referencing the same array

[polar acorn]

It's going to have both myNoSizeArray and otherArray referencing the same data

[timid ember]

yes, i am trying to use System.Data.DataTable().Compute because i am trying to make something not have multiple if statements for each operator

[shell sorrel]

no its just going to assing myNoSizeArray to otherArray

myNoSizeArray will still exist if youj have a other reference to it

[rich adder]

no reference types dont create deep copies like that, its the same object

[polar acorn]

Then you need to compute first. The formula itself is not a double

[polar acorn]

-

[verbal dome]

I like how we gave the same answer in 4 different ways

[polar acorn]

If you subtract a value in Update, it's going to subtract that value every frame

[fervent abyss]

so they both will have same data from otherArray?

[polar acorn]

They will both be the same array

[shell sorrel]

they will both be the same array

[rich adder]

its literally pointing to the same object in memory

[polar acorn]

They will be two different variables holding a reference to the same array

[fervent abyss]

oh ok because i dont trust myself

💀

[shell sorrel]

no data copy has taken place, you just end up having mySizeArray point to the same data as otherArray

[fervent abyss]

ok

[shell sorrel]

so if you modify one, they both get modifed in this case

since they are the same object in memory

[polar acorn]

If you did this:

myNoSizeArray = otherArray;
myNoSizeArray[0] = "Fungus Amogus"
Debug.Log(otherArray[0]);

The output would be "Fungus Amogus"

[rich adder]

if you want a copy then you need to make a new array with same size and copy over data (if the items in the array are also reference types you need to cerate a new obj for each one or you're just putting the same objects)

[timid ember]

what an example

made me shed a tear

[bright arch]

ahh there has to be a way to do this right? or at least achieve something to the same effect?

[rich adder]

just create the array awake or something

[verbal dome]

If you want to use variables in a initializer they should be const or static

[timid ember]

i am super new to unity i only know till input.getkey(keycode) and input.GetMouseButtonDown() sry

[rich adder]

yeah you can def do that too, you just won't be able to ever change them outside of code / initilizer (in the inspector for example)

[polar acorn]

All of the stuff outside of a function is going to run at creation time. Thise variables don't actually have any data yet at the time that array initializer is run. You'd need to do it in a function so all those variables are guaranteed to exist by then

[timid ember]

also, this error confuses me as if it doesnt convert, why does it work on the tutorial? is there s library im missing?

currentl impoted system.data

[rich adder]

can you show which line this is throwing, hard to say without context

        }

    }

[polar acorn]

What is Clac.cs line 18

[rich adder]

that doesnt show what DBNull is and what ur trying nvm

[timid ember]

public void ans

which runs answer=system.data.whateverthelongcode

[polar acorn]

Then you probably need to save your script and try again to get the actual line number

[verbal dome]

Should probably check if Compute returns a DBNull or not

[timid ember]

wheres my namespace

[rich adder]

its fine now but 18 is open bracket for some reason so 🤷‍♂️

[timid ember]

added it

[polar acorn]

You could use a Linq query.
playerOwnedAccessories.Where(acc => acc.player == playerToLookFor).FirstOrDefault()

It'll check each element, store it in the temporary variable acc, and if that acc's player is equal to playerToLookFor, it'll retrieve it. FirstOrDefault will ensure you get exactly one answer, or null if there are none.

something with the varibles with t

it using in other scripts

idk it doesnt work the varbles arent working

[timid ember]

11234 this is my error floo

[polar acorn]

what doesn't work

[polar acorn]

Okay, line 34 is still nothing with code on it. Save the script, run it again. Don't change the script after getting the error and posting it

[pulsar meteor]

Debug.LogError("NPCInteractie script not found!");
} i get this

but why idk

[languid spire]

Are you still trying to use a data table?

[timid ember]

i use if statements like that

[polar acorn]

Okay, good. Finally. That means npcInteractie is null. Where do you set it

[timid ember]

im just trying to see the problem there, your suggestion worked so my assignment is done

thanks

[pulsar meteor]

on start?

[polar acorn]

Where?

[languid spire]

the problem is your datatable is empty and Compute works on the rows in the datatable as per the documentation I linked to you

[pulsar meteor]

in the start from ItemInteractie

[polar acorn]

Show the line that sets npcInteractie

[polar acorn]

This is irrelevant

This is a function named npcInteractie on a different object

I'm asking you

where do you set the variable

on the object that is giving the error

[pulsar meteor]

NPCInteractie [SerializeField] ItemInteractie itemInteractie;

[polar acorn]

Okay, good. Your issue is that CurInput does not evaluate to a result from new System.Data.DataTable().Compute so it returns null, which is not a double

[pulsar meteor]

never mind i didnt add my Serelized field

[polar acorn]

That is where you create the variable. Where do you set the variable

[nocturne kayak]

Welp, that didn't work too well

[storm cedar]

Could someone explain why this coroutine freezes my game for a split second when called to activate a very simple UI? I've narrowed it down to the UI being the issue, but it makes no sense why it would be. The UI in subject:

[timid ember]

are datatables complex?

[polar acorn]

Whenever any object on a Canvas is changed (including enabled/disabled), the entire canvas repaints. If this is a small panel on a complex UI, it'll take a while to repaint the entire UI

[wintry quarry]

Have you checked the profiler?

[languid spire]

not at all, a datatable comprises of DataColumns and DataRows

[willow iron]

public class MouseLook : MonoBehaviour
{
    private Vector2 Move;
    private Vector2 Look;
    public float mouseSens;
    public Transform playerBody;
    float lookx;

    // Update is called once per frame
    void Update()
    {
        lookx = (Look.x * mouseSens * Time.deltaTime);
        playerBody.Rotate(lookx * Vector3.up);
    }
    public void OnLook(InputValue value)
    {
        Look = value.Get<Vector2>();
        
    }
}```

[storm cedar]

I know that, but if I enable/disable it without the coroutine it doesn't lag (it's not a complex Canvas)

Also I did check the profiler @wintry quarry, and it spiked from scripts, when called the coroutine to activate the UI.

[verbal dome]

Why ping me without showing what you tried etc.

[timid ember]

use it at the bottom too

[willow iron]

turning is very slow and stilted and remains same speed no matter spead of mouse

[wintry quarry]

which scripts? Check the particluar code that's doing it. If it's your code, you can optimize it

[nocturne kayak]

My bad, game recorder's not working too well for some reason, sorry

[polar acorn]

What calls ShowUIForSeconds

[nocturne kayak]

https://hastebin.com/share/esojehupet.java

[polar acorn]

Don't multiply mouse movement by deltaTime

[nocturne kayak]

hastebin interpreted it as a java file, interesting

But main thing is

[polar acorn]

It's already framerate independent

[nocturne kayak]

adding the axisHandler offset does jack

subtracting it creates a feedback loop

[verbal dome]

Yeah that could as well be Java

[nocturne kayak]

i'm adding it on update, so

[nocturne kayak]

Why's that?

[verbal dome]

C# is "Microsoft Java" after all

[nocturne kayak]

Huh

[verbal dome]

It was originally based off of java
E: Not technically, but syntax/design wise

[nocturne kayak]

I remember someone saying that a while back, but i don't quite understand what differentiates it

mainly because i don't know java.

[willow iron]

still moving at the same speed even without deltatime

[timid ember]

so i need to fill th datatable to use it?

[timid ember]

how do i fix that

[nocturne kayak]

Back to the task at hand, transform.position is set to new pos, which is then added to axishandler offset, which changed the transformPosition, which becomes newPos, which is added to axisHandlerOffset, ad infinitum

[polar acorn]

Don't try to parse CurInputs that aren't Computable expressions?

Do you even know what CurInput is when it fails?

[nocturne kayak]

So i don't understand the course of action to stop that here

[timid ember]

something like 0/0?

[polar acorn]

What is calling OnLook? What Input Action is that mapped to?

[polar acorn]

Is this a guess, or did you check what value it was when you got the error

Because you can just... check

you don't have to assume

[timid ember]

how do i do that, i take 2+3 and the answer would compute but stops at dbnull, which is datatable

[polar acorn]

Log it

[timid ember]

what

[polar acorn]

Log it

log CurInput

see what it logs before the error

Basic debugging

[verbal dome]

I got too much brain fog atm to give you the answer
Btw post the whole script

It could be fixable if you don't make the handles children of the cube

But then you'd have to redesign it a bit

[storm cedar]

Sorry it took me a bit to reply was cooking

[polar acorn]

Is this script on multiple objects? The hasNotepad bool should prevent it from running multiple times, but maybe a bunch of copies of this are running it at the same time?

[willow iron]

there we are

[storm cedar]

No it isn't, and it serves a single small purpose and yet so hard to do for some reason

[timid ember]

i feel its wrong, it should output "4+3"

[polar acorn]

What is the last log before the error occurs? You probably want to disable "collapse"

[timid ember]

not having collapse makes my console miserable but here you go

[polar acorn]

Okay, assuming your log is right before the error, then it would seem 3 evaluates to DBNull

[timid ember]

but how

because a value wouldnt make it null

unless the data type is wrong

wait

[storm cedar]

@polar acorn chagpt has no idea whats causing this either

[night raptor]

ChatGPT has very very little clue of anything in general

[polar acorn]

Instead of using a composite binding, you want to use a normal binding. Composite bindings are for creating analog outputs out of digital, so it detects if any movement occurs, and treats that as "1". Your "Look" action should look similar to the MouseAim I have here. You can also add a composite for the keyboard, just don't use a composite for the mouse.

[polar acorn]

Can you show the profiler that's showing the spike? It should say what functions are taking up the time if you inspect it closer

[storm cedar]

Yeah will do that in a few mins

[timid ember]

my data type was wrong all this time?

[willow iron]

aye, thanks

[timid ember]

but operators wont work in int or double

make a different string called operator and make a big mess of it?

[timid ember]

messiah where are you

[verbal dome]

#💻┃code-beginner message

[polar acorn]

Man I hate how similar some of the colors on this are, but it looks like that spike is from Garbage Collection, not Scripts

[storm cedar]

I've disabled everything but the scripts when I first tested it and it spiked hard

[polar acorn]

It's one of the dark browns, and GC is the most likely one of the dark browns to suddenly take 266ms and then shoot back down

A single coroutine will produce some garbage, but it shouldn't produce that much

[storm cedar]

one sec

[timid ember]

Why is it failing? The first command would convert 4+3 into double but isn't + can't be converted into double it would stay string right?

making it int(4) string "+" int(3)

I'm new so I might sound stupid as fk

but isn't that what compute does

[languid spire]

you are not listening to a word I am saying, I've given you the answer twice already

[polar acorn]

Show the updated code, with your logs

[storm cedar]

Here's screenshot with everything but them 3 components enabled, it's the scripts

[polar acorn]

Because literally none of these throw errors.

[timid ember]

as per my knowledge, static wouldn't effect right?

also, unity is taking these inputs as
4
+
3
which makes me think they aren't in the same string

[polar acorn]

Okay yep that definitely looks like scripts. Let's do a quick sanity check - the first line of your coroutine, add this line:

Debug.Log($"Coroutine started on object {gameObject.name}");

And check to see if it's showing up multiple times

[verbal dome]

Wait maybe this is the TextMeshPro empty character issue?

[polar acorn]

Just show the code

[storm cedar]

I tried that before, it's only once

[polar acorn]

Possible, now that you mention it. If the TMP text is an Input box's attached text

[timid ember]

wtf happened to my calc

[polar acorn]

🤔 Okay that's odd. I have no idea why a single coroutine would be so resource intensive

[timid ember]

i didnt drag anythn

[storm cedar]

Exactly

[polar acorn]

At this point I'm stumped. I dunno if anyone else can see anything I don't but I really don't see how this could be taking up so much time unless there's a lot of stuff on the canvas, or the coroutine's running multiple times, and it seems neither is the case?

[verbal dome]

Regarding your main issue, is the input string coming from a text object under a TMP input field?

[timid ember]

yes

wait no

its tmp

not inputfield

it changes the text

[polar acorn]

It's just a raw TextMeshProUGUI, and not a child of an Input box?

[timid ember]

yes

its under panel as i saw in he tut

[polar acorn]

Okay, then it's not the invisible character issue

regarding ur earlier req

[polar acorn]

You're logging CurInput after the error

I said to do it before

literally the line right before

the logs are worthless as they are. If there's an error, we won't see it

The stuff that was logging was the things that did work

[timid ember]

its before error

[polar acorn]

No, it isn't

[timid ember]

the error is at line 36, answer=system.convert.longessay

[polar acorn]

You see how the green circle is after the red circle

[timid ember]

im dumb

[polar acorn]

Meaning if there is an error in ans, the log does not happen

[timid ember]

this isnt log?

[polar acorn]

These are logging after the line that throws the error

meaning that it passed the problem and printed

so, by definition, these are the values that did not cause an error

you have to log before the error. Not after.

[storm cedar]

There's nothing on the canvas active when the coroutine gets called

[polar acorn]

Once an error occurs, the code stops

i see

[polar acorn]

as people have mentioned a long ass fuckin time ago

[timid ember]

on public void buttontap(), the function takes input

[hallow acorn]

https://gdl.space/jayoficiri.cpp why does it not recognise any collisions please i dont get it i also tried a print() in the ontriggerenter and exit functions

The Three Commandments of OnTriggerEnter:

1. Thou Shalt have a 3D Collider on each object
2. Thou Shalt tick isTrigger on at least one of them
3. Thou Shalt have a 3D Rigidbody on at least one of them

[timid ember]

  if(val== "=")
        {
            ans();
        }
        else if(val== "C")
        {

        {
            CurInput=val;
            UpdateDisplay();

val is a string on buttontap(string val)

public void

[polar acorn]

When val is "=", it runs ans which reads the value of CurInput, which is currently nothing

[timid ember]

on no input that would be the case, or it would always be the case?

[polar acorn]

It's called a joke

[timid ember]

+= was the issue

[polar acorn]

Did you tick the box

[timid ember]

i was seeing this vid at 140

[polar acorn]

Yes. You were overwriting the command every time anything was input

even if it was null

instead of just adding empty to the running function

which would have left it unchanged

[timid ember]

i wasted 4 hours because of video quality

[hallow acorn]

Pray, what dost thou meaneth?

[polar acorn]

Okay, so, in computers, there's a thing called a checkbox

when you click it, it gets a ✅ in it

did you do that

[steep rose]

he is telling you how to fix your problem

[hallow acorn]

Verily, I dost believe so.

[steep rose]

AKA click the Istrigger box

[polar acorn]

Okay, show the inspectors of both objects

[timid ember]

whys the error still there after save

[polar acorn]

What's the log say the value is when it errors

[timid ember]

null

[polar acorn]

So, this would probably be why the tutorial had try-catch but it's a bad tutorial anyway and you shouldn't do that. Instead just check to make sure the length of CurInput is greater than 0 before running the stuff in ans

If its length is 0, don't do the calculation

[hallow acorn]

Pray, my noble squire, cast not thine judgments upon me, yet I confess, I hath overlooked the need for a rigidbody upon my terrain.

[timid ember]

curinput is privae

private, woudl it still show in debug.log

[polar acorn]

Then maybe you should have fuckin read the answer I gave instead of being a dick about it

[polar acorn]

You've literally been logging it the entire time

If private were a problem it wouldn't compile

[hallow acorn]

ok chill bro im sry

[timid ember]

whys it debugging when i click twice

theres no answer btw it still says cant convert into null

[polar acorn]

What is the log before the error

[lofty lintel]

guys im still getting that jittering we fixed yesterday ( but actually i think this a bit of jittering was there yesterday too, I didn't change anything with script, only changed sprite which has nothing to do with it)

Script is in fixedUpdate

//Player Rotate Follows Mouse.---------------------------------------------------------------
if (PlayerRotates)
{
    //Debug.Log("Should rotate");
    Vector3 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
    Vector3 lookDir = mousePos - transform.position;
    rb.rotation = Mathf.Atan2(lookDir.y, lookDir.x) * Mathf.Rad2Deg + 270;
}

 Vector3 moveDir = new Vector3(moveX, moveY, 0f).normalized;
 Vector2 targetVelocity = moveDir * speed; // your movedirection * speed
 Vector2 velocityDiff = targetVelocity - rb.velocity;
 rb.AddForce(velocityDiff * acceleration);

[lofty lintel]

However if I turn off rotation script and try to rotate the other way (rotation doesn't work neither in fixed or normal update) but jittering stops

[verbal dome]

As a test, disable your camera movement so that it stays still. See if the character still jitters

[scenic escarp]

Please help! I have a two scene game where the audio player is important to the game working. It works fine when I run the game starting in the gameplay scene and have the audio source placed via inspector. But if I start the game from the menu, the game objects lose the reference to the audio source and this doesn't seem to work.

[lofty lintel]

In this case character stops jittering

[verbal dome]

What if you use MoveRotation instead of rotation

[lofty lintel]

Thats what im doing

it does stop jittering but actual rotation doesn't work

[timid ember]

empty (clicked 4 once)
4 (clicked 4 twice)

[verbal dome]

Oh so with "rotate the other way" you mean moverotation

[lofty lintel]

//Player Rotate Follows Mouse.---------------------------------------------------------------
if (PlayerRotates)
{
    //Debug.Log("Should rotate");
    Vector3 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
    Vector3 lookDir = mousePos - transform.position;
    //rb.rotation = Mathf.Atan2(lookDir.y, lookDir.x) * Mathf.Rad2Deg + 270;
    rb.MoveRotation(Mathf.Atan2(lookDir.y, lookDir.x) * Mathf.Rad2Deg + 270);
    //transform.rotation = Quaternion.LookRotation(Vector3.forward, mousePos - transform.position);
}

[polar acorn]

Did you add in the length check I suggested

[lofty lintel]

This is current script which stops jittering but stops character rotation aswell

//rb.rotation = Mathf.Atan2(lookDir.y, lookDir.x) * Mathf.Rad2Deg + 270;

if I use this rotation works but it jitters

[timid ember]

see my references (ignore the warning, it was because i misused a text)

[verbal dome]

Open rigidbody constraints, you don't have rotation constrained do you?

[timid ember]

onclick() and disptext in clac input

[lofty lintel]

yeah I don't know whats that

[verbal dome]

The "Constraints" tab in your rigidbody's inspector

[lofty lintel]

Did that

[timid ember]

this is for tmp

[verbal dome]

Yeah lol your rotation is frozen

[lofty lintel]

oh shit

wait I did that because of something as I remember

but wait i'll try

wow

Smooth! thanks.

[scenic escarp]

I realise I was asking this in the middle of another thing lol but if that's solved I'd really appreciate help here

[verbal dome]

Okay cool
@wintry quarry It seems like rb2d.rotation does break interpolation after all
The reason that MoveRotation didn't work was because the rotation was constrained

[lofty lintel]

Oh I see so we know that too now

so instead of using rb.rotation I should use moverotation() to not break interpolation

[verbal dome]

I was always under that impression
The 3D rigidbody.rotation doc says:

If you want to continuously rotate a rigidbody use MoveRotation instead, which takes interpolation into account.
While the 2D doc doesn't say much

@lofty lintel Could you quickly switch back to rb.rotation but keep it unconstrained

And see if it still jitters

[lofty lintel]

ok i'll check

Yes it jitters using rb.rotation especially when I rotate the player (which makes sense)

[lofty lintel]

wait how do I write code like this

[verbal dome]

Alright then we can safely say that rb.rotation breaks interpolation

[verbal dome]

Surround with two of these ` on each side

[lofty lintel]

rb.rotation

I see, thanks.

[cosmic quail]

does rb.velocity break interpolation too?

[verbal dome]

Nope, that's fine

[steep rose]

afaik no

[cosmic quail]

oh that's good

[lofty lintel]

no im using that

[verbal dome]

Only rb.rotation, rb.position and ofc transform.position/rotation which you shouldn't ever use with rigidbodies

[timid ember]

how do i add that? by making CurInput=val? or making it = a value

[steep rose]

i mean i could see why using rb.rotation would break interpolation because you are setting the rotation manually

[lofty lintel]

same as transform.position

[steep rose]

you would most likely use moverotation

[cosmic quail]

i think you mean rb.rotation instead of rb.velocity

[lofty lintel]

yes

[verbal dome]

Oops yeah, edited

[steep rose]

keep in mind some things apply in 2D than 3D because they use a different physics engine

[timid ember]

now that digiholic died(rip), im now gonna cry

[steep rose]

[timid ember]

we came close to solving my issues

he has a life lmao

[timid ember]

welp

ye ik

[steep rose]

be patient

[timid ember]

ik bro i was just coping

[tawny edge]

TLDR; I'm trying to make it so my car won't be able to turn if he is not moving or forward but my code didn't work.
my main objective here is not to primaly understand why this code did not work for learning purposes

I thought of making the car be unable to turn while he is not moving back or forward so i thought that making it so that
(if the car isn't receiving forward or back input, then his horizontal Input will be zero).
I made a if statement with that logic and placed it in update to make it happen every frame.

Since my car rotation value is multiplied by horizontal input, i thought making it zero would multiply with everything there and make it all zero, nullifying any rotation.

As you can see in the video, it didn't work (i made sure to save the code befor testing it).

Why didn't that work? what did i miss?

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

public class PlayerController : MonoBehaviour
{
    //Private variables
    public float speed = 20.0f;
    public float turnSpeed = 45.0f;
    public float horizontalInput;
    public float forwardInput;
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {

         if (forwardInput == 0)
    {
         horizontalInput = 0;
    }


        // here, we get the player's Input
        horizontalInput = Input.GetAxis("Horizontal");
        forwardInput = Input.GetAxis("Vertical");

        //we'll move the vehicle forward based on vertical input
        transform.Translate(Vector3.forward * Time.deltaTime * speed * forwardInput);
        //we'll rotate the vehicle based on horizontal Input
        transform.Rotate(Vector3.up * Time.deltaTime * turnSpeed * horizontalInput);


    }
}

[steep rose]

#💻┃code-beginner message

[verbal dome]

You should also multiply your rotation with the Absolute value of forwardInput

[lofty lintel]

im a beginner too but with my primitive brain I would just detect if its moving and rotate it only when moving

[verbal dome]

Or just make it zero when forwardinput is near zero

Oh ok I see you tried that here:cs if (forwardInput == 0) { horizontalInput = 0; }
But you should do that after setting it to the input value

[steep rose]

also i see you are translating a RB

so it will ignore collisions

[verbal dome]

Also GetAxis has some smoothing by default so it might take a small while to reach 0

[tawny edge]

yeah, so my main goal isn't even trying to find other ways to make it work, but to understand: why didn't this aproach worked? what did i miss?

[verbal dome]

Wait is this from the Unity Learn site?
The one lesson where they teach you to use transform to move a rigidbody? 🤦‍♂️

[tawny edge]

yes

is that bad?

[steep rose]

yes as it will ignore collisions

[verbal dome]

Yes, shame on whoever wrote that

[steep rose]

and pretty much everything with the RB

[red helm]

Hey guys, can you build and run a project that has a database to your phone?

[verbal dome]

You might miss collisions entirely

[lofty lintel]

I've learnt that too like months ago before dropping unity xd

[tawny edge]

wait... but the collisions to the ground and the boxes seems to have worked fine...?

i'm confused

[timid ember]

confused on the datatable one

[verbal dome]

Well I just sort of explained it, but the if statement that you used to set horizontalInput to zero doesn't do anything since you changed horizontalInput after it

[timid ember]

it works with console.writeline?

[steep rose]

if you go forward into a wall it should ignore collisions

[verbal dome]

transform doesn't always ignore collisions, it's just not reliable

It might seemingly work fine in a small demo like this, but them teaching it on the unity learn site is just awful

[tawny edge]

i placed that at the bottom of my update and it didn't change the result...

[timid ember]

this is my refined code

im confused as to which operand is needed

[verbal dome]

That's also wrong, at the bottom of the update you have already rotated the car
You should do it after the Input lines, but before rotating the car

[timid ember]

the debug is for checking errors

[verbal dome]

Code executes from top to bottom

[verbal dome]

Are you trying to parse an expression thatis just "="?

[tawny edge]

IT WORKED!!!!!!
THANK YOU!!!

[timid ember]

its supposed to compute "1+3" when i hit =

i changed it to debug the log of answer, which computes the string

im dying

[short hazel]

Seems like you still add the = when you hit it, so you pass 1 + 3 = to the DataTable which is obviously invalid

[timid ember]

updated code btw

[timid ember]

so i remove on button click for =?

[tawny edge]

If the main website of the engine is teaching me to work with it in the wrong way....
then what should i do? What is the right or good aproach that would be expected of me in a work enviroment?

[short hazel]

No, you do not add the = to the string when you receive it

[timid ember]

so, how do i make = onnly execute the code?

[steep rose]

use the rigidbodies methods so Addforce,Velocity,moverotation,etc

usually you shouldnt use the RB transforms due to inacurate collision detections

but for something small, i believe your okay

[verbal dome]

I'd like to believe that mistakes like this are rare in the Unity Learn site, but I can't say for sure.
I mostly learned by:
-Trial and error
-Reading documentation
-Googling my issues, a lot of them are answered in the unity forums

[short hazel]

Just like I told you, do not do CurInput += val; if you're not certain you'll execute UpdateDisplay().
This means that you need to move that line in the else so it only executes when you type a number or an operator (and not an = or a C, because yes it'll add the C at the end of the expression too!)

[steep rose]

but i have to say, its refreshing for a beginner to want to learn so thank you 😁

[timid ember]

thats what i did earlier, but it was causing it to not give any output in debug.log(CurInput)

[steep rose]

failure is the only way to learn so everything you said is very true

[tawny edge]

thank you to both Osmal and dec_ves for explaining that to me.
I kind of suck when it comes to know what to look for when learning to code and this is the type of stuff it could take my a LONG time until i discover, if ever.

[timid ember]

causing the error(cant convert dbnull into double)

[queen adder]

ello

[steep rose]

well thank you for being a good sport, and if you need help feel free to ask and you will get used to it eventually everyone starts somewhere

[short hazel]

Your expression failed to compute or was empty. Log it before trying to evaluate it using the datatable

[timid ember]

yes, its empty in beginning and changes value when val(onbuttonclick) is used by [0-9]

or when +,-,/ and * is used

[short hazel]

Prove it with a log, right before you do new DataTable().Compute(...)

[timid ember]

do i simply declare it as a string without value?

[tawny edge]

thank you for taking your time to teach me!
I have a ton more doubts but i think they are too ambitious for me to understand at the moment.

That said, would it be okay for me to continue to learn using the Unity learn course?
So far it is the best guided course i found...

string is val, buttons have refernce to clac.buttontap

inputs would register into val and change curinput

but curinput doesntchange

[short hazel]

Debug further. Log the value and the Length of val, make sure the else part is even executed

[timid ember]

curinput
val

oh no.

need help yall yo

[polar acorn]

Check the length of it. With an if statement. Why would setting it to a different value have anything to do with checking length?

[timid ember]

what exactly does length mean?

[short hazel]

The length of a string is the number of characters in the string

[timid ember]

how does an if statement give length

[deft grail]

you get the length, then you check its value to see if its something
the result of that is a bool which is what an if statement is for

[jade tartan]

Well... After doing a tuto to allow my character to respawn, I noticied that sometime my character respawned into the ground. After checking the comments section, I found out that i needed to to have the "Player" object deactivated when entering inside the DeathZone and then reactivate it with a Coroutine, but the one who gave that solution forgot how they did that, so I tried by creating a boolean variable with a script for activating Player. Here's the tuto in question (in French) and the current states of both the Player Activation and Deathzone scripts: https://youtu.be/5MmX3Mea29Y https://hastebin.com/share/agivupigur.csharp

}

It won't swap animations even though movement and everything else works

[wintry quarry]

It's case sensitive

[upper thistle]

Oh

that's a moment lol, thanks

[upper thistle]

Do you happen to know how I can make an animation end the moment the transition starts?

or make it faster at least

[lofty lintel]

Guys how would I reach all of those in loop
(like inside code)

float min = StickUiParent.Find("Spawn").position.x - 9f;
float max = StickUiParent.Find("Spawn").position.x + 9f;
float randomPos = Random.Range(min, max);
if (LastPos.IsUnityNull())
{
    LastPos = new Vector3(
        Random.Range(StickUiParent.Find("Spawn").position.x - 9f,
        StickUiParent.Find("Spawn").position.x + 9f),
        Random.Range(StickUiParent.Find("Spawn").position.y - 1f,
        StickUiParent.Find("Spawn").position.y + 1f), 1);
}
else
{
    //StickUiParent.Find()
    //while (randomPos >= LastPos.x - 0.4f || randomPos <= LastPos.x + 0.4f)
    //{
    //    randomPos = Random.Range(min, max);
    //    if (randomPos <= LastPos.x - 0.4f || randomPos >= LastPos.x + 0.4f) break;
    //}
    LastPos = new Vector3(
       randomPos,
       Random.Range(StickUiParent.Find("Spawn").position.y - 1f,
       StickUiParent.Find("Spawn").position.y + 1f), 1);
}```
Basically what im trying to do is that when I initialize them in position I don't want any of them to be like too close to each other. I want them to be aligned with a bit of distance.

And second question is what I asked in [#📲┃ui-ux](/guild/489222168727519232/channel/502171135350407168/)  so basically how do I move stoneUIs behind that brown UI (im confused since they don't have order in layers.)

[wintry quarry]

Turn off exit time

[rocky canyon]

set the transition speed to 0 w/ no exit time

[lofty lintel]

One approach I started is using tags on StickUI prefabs.

[timid ember]

bruh lol when length=<0

[wintry quarry]

stop using GameObject.Find.

Start learning to use arrays.
or using transform.GetChild(n)

[upper thistle]

Where may I find this?

[pliant pecan]

maybe a weirdo question, but i want to make a script that only exists to do one thing, and will only ever be called for that one purpose. I want ohter scripts to be able to call functions in this script. How would i approach this?

[upper thistle]

don't see it anywhere

[rocky canyon]

click the transition arrow

[upper thistle]

Oh

[wintry quarry]

That's how all your scripts should be ideally. What part is confusing you?

[upper thistle]

Thanks, I appreciate you guys

[lofty lintel]

I do know how to work with arrays in c#, but im trying to get like array of those StickUIs
does transform have GetChildren?

[pliant pecan]

hm, i have a script on an empty object, but how do i reference the outside "helper" script? do i also put on the object?

[wintry quarry]

it has childCount and GetChild

so you can use it in a loop

Also why not just put them in an array in the inspector though

[lofty lintel]

Yeah but it takes index I don't want that

[lofty lintel]

they spawn later on in hierachy

[wintry quarry]

That depends on how you want it to work. Is it associated with that object?

[wintry quarry]

Add them to a list as you spawn them,

then you have the list at all times

[wintry quarry]

yes you do

use a for loop

[pliant pecan]

No not at all, the "helper" script organizes a bunch of data, for the "main" scripts to use.

[wintry quarry]

for (int i = 0; i < transform.childCount; i++) {
  Transform child = transform.GetChild(i);
}```

[lofty lintel]

 public GameObject StickUI;
 public Transform StickUiParent;
 public GameObject StoneUI;
 public Transform StoneUiParent;```

[wintry quarry]

if you want

up to you man

[lofty lintel]

alright i'll try.

[wintry quarry]

what kind of data

"global data"?

Make a singleton

[lofty lintel]

oh this does make sense but only one problem I have with that is that I have spawn object inside that too so it will count as child.

[pliant pecan]

Nah i want to send a list to the helper script, and get back a messed up version of that list

[timid ember]

alright yeah im giving up on unity

[wintry quarry]

spawn thjat object separately. Make the hierarchy clearner. Make one container object just for these things.

Or, better yet, as I mentioned, just keep the things in a List as you spawn them like I said before

[timid ember]

ive asked the solution of an error for 9 hours for no solution lol

[lofty lintel]

 StickUIs.Add(Instantiate(StickUI, LastPos, Quaternion.identity, StickUiParent));```
This would work well right?

[wintry quarry]

Maybe you just want a static method? You're being really vague

[wintry quarry]

yes

[upper thistle]

I can't seem to jump on my character. Not sure if it's to do with how unity handles IsGrounded or not with the CharacterController. I can't seem to find where you can check if you're grounded or not

[deft grail]

then spend more
switching engines wont fix your problems there will be new errors there, if you decide to switch

[pliant pecan]

I'm gonna be honest, i literally just dont know how to reference another script while im in one script. Do i need to have a component or does calling it just "create" it?

[timid ember]

who said im switching

[silk night]

I am not sure if jumping is part of the character controller by default

[timid ember]

ow

[verbal dome]

None of this is unity specific by the way. You might as well ask in the C# discord

[upper thistle]

I have it setup in the code. I think it has to do with the isGrounded

[silk night]

Then please show your code

[upper thistle]

Right here

[silk night]

"Jump" is not a button 😄

Use KeyCode.Space

[upper thistle]

ah okay

Thanks fam

[steep rose]

can you not use the new input system and name it as such?

[deft grail]

its part of the input system if im not wrong, so it is a button

[verbal dome]

GetButton takes a string, if you wanna use KeyCodes then use GetKey

[silk night]

oh shoot

thought that was the old one

[steep rose]

he must not have it set up in the input system

[upper thistle]

I think the issue is grounded

Cause the rig will jump right at the start of the game

but can't use it again

[silk night]

You should log at which part the operation fails

(or debug if you know how to)

[verbal dome]

Also I think "Jump" is defined by default
https://docs.unity3d.com/560/Documentation/uploads/Main/InputAxis.png

[upper thistle]

yeah, just figuring out C# syntax atm

used to lua

The issue is in regards to grounded

[silk night]

Just put some Debug.Log("TEXT") in there

and see where it stops

[upper thistle]

I removed it and I can jump, but not sure how to fix this issue. Is there a place I can check if IsGrounded is true or not

[steep rose]

the built in character controller grounded works as it should

its integrated into it

[upper thistle]

Yeah, I think the issue is with my rig

that's what I'm thinking

[silk night]

does your character lift off the ground at all or just not play the animation?

[upper thistle]

like the height/scale

[upper thistle]

one sec, I'll check

[steep rose]

but you can do your own grounded function as well by doing a raycast

[upper thistle]

Is there a way to do an if not statement in this?

Like if, but the opposite

[steep rose]

spherecast etc

[silk night]

if (!condition)

[steep rose]

keep in mind the character controller itself has to touch the floor

so if your model is suspending it, it will not work

[upper thistle]

this isn't hitting the floor then right

[lofty lintel]

How would I get this without find() or why is find() a bad practice?

[deft grail]

put the center Y to 0

[wintry quarry]

Again, store them in a list, or iterate over the children of StickPlacer

Find is extremely slow

and finicky

[lofty lintel]

no no that's not what im asking

but ok I understand now

[wintry quarry]

what are you asking?

[upper thistle]

Still floating

[steep rose]

try changing skin width

[lofty lintel]

i just got other idea so I'll do it and ask in the end if it was a good practice like that, also I am kind of forced to use while loop...

[upper thistle]

to what? Don't see any changes in it. Lower or higher?

[steep rose]

just mess with it

[wintry quarry]

You are never forced to use a while loop

for and while can both be used for anything

[upper thistle]

thanks, that was it

[steep rose]

if skin width is to small/big it messes with it

[upper thistle]

It was oddly too much

[steep rose]

glad we were able to fix it

[upper thistle]

had to reduce it to 0.03

[short hazel]

It doesn't. It's a property on the string:

string s = "Hello!";
Debug.Log(s.Length); // prints 6 to the console

[upper thistle]

appreciate the help man

[lofty lintel]

yeah makes sense

[upper thistle]

I oddly can't jump while standing still, but can while moving. Is there a reason for that?

[timid ember]

yall thank you for troubling urself for helpin but im too sleepy to continue coding, its like 5 am i havent slept

3 days in a row im dyin but really appreciate yall sticking oout

[polar acorn]

How long something is

[steep rose]

not sure why it would be doing that you can try to either mess with skin width again or use you own grounded boolean

other than that, im not sure why since you have nothing checking if you can jump other than the keycode

[verbal dome]

Low Skin Width can cause the character to get stuck.

https://docs.unity3d.com/Manual/class-CharacterController.html

[upper thistle]

Ah it was the center needing to be lowered

[round mirage]

how i can make my dino jump like in the real game ? i have tried with constant force but idk if it look good.

[steep rose]

and yes as Osmal said if you make your skin width to low it will get stuck

[upper thistle]

is there a task wait in C sharp I can use or a coroutine to delay my jump? Or can I setup an animation event to listen for somehow?

[upper thistle]

thanks

[upper thistle]

Reason for this is it's kind of a charge jump

[silk night]

Raise the gravity and jump force

would be an easy way to speed it up

[steep rose]

you can use a coroutine or invoking it to delay a jump

try invoking it first

[upper thistle]

What's invoking it?

never heard of that in lua

[steep rose]

this is not lua

[silk night]

invoking a method ~= calling a method

[steep rose]

https://docs.unity3d.com/ScriptReference/MonoBehaviour.Invoke.html

[lofty lintel]

looks like my logic didn't work after all.

float minX = StickSpawn.position.x - 9f;
float maxX = StickSpawn.position.x + 9f;
float minY = StickSpawn.position.y - 1f;
float maxY = StickSpawn.position.y + 1f;
float randomXPos = UnityEngine.Random.Range(minX, maxX);
float randomYPos = UnityEngine.Random.Range(minY, maxY);
if (StickUIs.Count == 0)
{
    SpawnPos = new Vector3(randomXPos,randomYPos,1);
}
else
{
    SpawnPos = new Vector3(randomXPos, randomYPos, 1);
    foreach (var stick in StickUIs)
    {
        while (randomXPos <= stick.transform.position.x - 10f || randomXPos >= stick.transform.position.x + 10f)
        {
            randomXPos = UnityEngine.Random.Range(minX, maxX);
            SpawnPos.x = randomXPos;
            if (randomXPos >= stick.transform.position.x - 10f || randomXPos <= stick.transform.position.x + 10f) break;
        }
    }
   
}
StickUIs.Add(Instantiate(StickUI, SpawnPos, Quaternion.identity, StickSpawn.parent));

what do you think...

[upper thistle]

I know lol

okay cool

invoking, I'll try that

[wintry quarry]

what are you trying to do?

[lofty lintel]

Just to be clear what im trying to do is to not spawn sticks too close to each other

[wintry quarry]

that code doesn't make much sense

use the Graphic raycaster to check if your chosen position has anything there

[verbal dome]

I just googled for the fun of it, if ~= is an operator in some languages
First result says it means != in LUA 😆

[lofty lintel]

wait look

[silk night]

well shit 😄

i meant almost the same as

[verbal dome]

Yeah I figured

[upper thistle]

Thanks. Invoking it worked @steep rose

ty for the reference

[lofty lintel]

On the left its all right, on the right that's what I want to avoid.

[wintry quarry]

My recommendation

[lofty lintel]

would Graphic raycaster check that distance?

[wintry quarry]

idk what you mean by that

[upper thistle]

definitely. I think I know a lot of unprofessional terminology since I coded for a bit on roblox

seems to have different names here

[lofty lintel]

Like I want to check if the current spawn area is available

And im tyring to do that with while loop

[wintry quarry]

I'm aware what you want

I recommend using the raycaster

[steep rose]

it would since this is a real programming language that people use in a profesional enviroment

[lofty lintel]

basically what Im trying to do is that lets say One stickUI spawned at X position 5, if There is another one spawning it should either spawn at X greater than 7 or lower than 3

[steep rose]

but you will probably get used to it fast

[upper thistle]

Well, roblox has an incredibly professional environment all over too. I just wasn't involved in it

[wintry quarry]

you can do this:

do {
  // pick a random spot
  // use the raycaster to check if there's anytthing in that random spot
} 
while ( /* something was in the spot you picked */)

// spawn at the spot

Just don't get caught in an inifnite loop

[upper thistle]

Lua is also competent in a lot

appreciate the help though

[lofty lintel]

how would I check if something was in spot with raycaster, and I'll try to do rest.

[lofty lintel]

Didn't really understand anything in that doc

xd

[ruby python]

Am I right in thinking that Scriptable Objects can reference things in the project, but not in the scene? (as in public fields?)

[lofty lintel]

if(!StickUI.GetComponent<GraphicRaycaster>().blockingObjects.IsUnityNull())

[upper thistle]

Does anyone know if after jumping, I can then start listening for isGrounded temporarily? I can't do it prior for a few reasons

Not sure how to approach that

[lofty lintel]

i don't think im going right way...

[hexed terrace]

non-scene objects cannot reference scene objects

[ruby python]

Yeah, but can they reference other non-scene objects (for example Materials?)

[steep rose]

its best to make your own isgrounded by using a spherecast or raycast or checksphere

[hexed terrace]

yes

[slender nymph]

yes, assets can reference other assets.

[steep rose]

then you can manipulate it in any way

[ruby python]

Right, thanks. I thought so, just wanted to make sure 🙂

[round mirage]

but how can i raise the gravity ?

[upper thistle]

I'm aware, but I'm trying to learn other methods first

[hexed terrace]

you could have just.. tried it 😉

[ruby python]

I'm planning my code, so wanted to check before I write it all and haveta rethink it. lol.

[steep rose]

like what?

[upper thistle]

like how to use coroutines or task.delays in unity

threading stuff

[silk night]

In the project settings under Physics

[steep rose]

you cannot modify the character controller grounded afaik

[deft grail]

on your Rigidbody2D component if you are using it

[upper thistle]

I'm not going to lol

[steep rose]

this is why i mentioned making your own

[upper thistle]

that's not what I'm asking

[deft grail]

nvm you have a 3d one

[steep rose]

Does anyone know if after jumping, I can then start listening for isGrounded temporarily?
then what are you asking?

[upper thistle]

I want to either start listening for isGrounded post jump, not prior or delay and turn IsJumping off after 0.5 seconds

one of the two

[verbal dome]

If you're a beginner I recommend sticking to coroutines instead of async for now

[silk night]

If you think about threading either use the job system, or use UniRX / R3 ( - personal opinion)

[verbal dome]

Oh if you need multithreading then yeah you need something else than coroutines

[silk night]

As someone who recently had to learn it for my new job, I can only recommend R3 for async / multithreading

[upper thistle]

not atm, I may get into procedural gen a bit later but I'm too new atm to more complex code

[silk night]

oh that sounds like a perfect task for the jobsystem

[upper thistle]

I was doing procedural gen for a day and messing with perlin noise color maps and all that

never even touched code remotely that complex on roblox lol

[upper thistle]

Cool, I'll keep that in mind for sure

[upper thistle]

Rn, just figuring out simple steps forward with characters

[steep rose]

then use a coroutine

and wait for 0.5 seconds and turn jumping off

[silk night]

just make sure the user cant jump 15 times by spamming space before isgrounded turns off 😄

[steep rose]

i would check if grounded in jump if statement and i would also suggest moving all of that logic to a private void Jump() so you can call it whenever

[lofty lintel]

do{
     randomXPos = UnityEngine.Random.Range(minX, maxX);
     SpawnPos.x = randomXPos;
 } while (!StickUI.GetComponent<GraphicRaycaster>().blockingObjects.IsUnityNull());```

[upper thistle]

yeah, exactly. Just doing a bit of a challenge by having a delayed jump

good practice exercise

[lofty lintel]

do
{
    randomXPos = UnityEngine.Random.Range(minX, maxX);
    SpawnPos.x = randomXPos;
    issomething = !StickUI.GetComponent<GraphicRaycaster>().blockingObjects.IsUnityNull();
} while (issomething);```

Shit I think While broke my game

yeah

[slender nymph]

considering that condition cannot change inside the loop then your loop will never end

[lofty lintel]

just realized it won't

And i don't know how to use graphicraycaster

[slender nymph]

either just make that an if statement and stick it in Update (if it isn't already), or use a coroutine and yield return null inside the loop

[lofty lintel]

u know what im trying to do?

[delicate zinc]

these scripts are meant to work together to let me pick up and drop items, but whenever i try picking up any item that isnt the latest one created with the script attached it doesnt let me drop it
its rly weird cos the debug.log that ive dropped it shows up in the console, but nothing else happens and it stays parented and kinematic

[slender nymph]

no

you need to actually Raycast with the graphic raycaster

[lofty lintel]

I chekced that doc but didn't understand anything

[slender nymph]

you need to call the Raycast method

[lofty lintel]

Like how?

[slender nymph]

there are beginner courses pinned in this channel, you should perhaps start there if you cannot recognize that you are missing the two parameters required to call that method.

[lofty lintel]

No I realize that haha

I just don't know what does those parameters take like what is PointerEventData or the list that it needs

Im good with c# i just have a hard time understanding Unity library

[rocky canyon]

https://gamedev.stackexchange.com/questions/93592/how-does-the-graphic-raycaster-component-work-in-unity

no worries.. at this point in time (starting learning and stuff) docs are a way of introducing you to functions and methods that unity uses.. ofc ur not going to understand all of them..

but the take-a-way is knowing what ur looking for.. keywords and stuff.. can help massively when doing ur own research or looking for other reference material

[lofty lintel]

I do that a lot but thats why I joined this server to like actually understand unity by getting help from people yk

[rocky canyon]

ofc ofc

[lofty lintel]

one thing now is that how would Raycast help me with that?

[rocky canyon]

i enjoy being part of the channel b/c of basically this.
i know how to search and learn my own stuff.. but i can't possibly know all of whats available

[lofty lintel]

yes ofc

[rocky canyon]

users here help introduce me to new functions and ideas on the daily (usually)

[lofty lintel]

yeah it's been two days since I joined and already got a lot out of this server

[rocky canyon]

the graphic raycaster is like ur normal raycast (shooting a lazer into the screen and seeing what it hits) .. but in this case its specifically for UI/ and Canvas

in ur case.. u could raycast onto the canvas and know whether theres already an object where u plan on spawning one..

if ther is.. u can ignore that position and find a new one

rinse and repeat

[inner folio]

Does anyone know why my TextMeshPro input field doesn't let me type in it? It's selected, but whenever I actually type, nothing happens

[rocky canyon]

it should...

is the game running?

[inner folio]

yeah

[lofty lintel]

yes but how would check if something was in this radius like for example there are 5 sticks aligned and there is 6th trying to spawn but it shouldn't touch any of other stickUIs radius, also I don't understand raycasting methods much thats why

[slender nymph]

this isn't code related, but do you have an event system in the scene? i don't see one in the hierarchy

[swift elbow]

event system?

[inner folio]

yeah i do, i think that might be the issue? but without the event system, the input box doesn't get selected when i enter into it

[rocky canyon]

is it possible that setting it selected every frame is stopping the input

[inner folio]

possibly

ill fix that

it's only selecting it whenever it's not focused so that should only happen whenever the terminal is first opened

[lofty lintel]

//Code to be place in a MonoBehaviour with a GraphicRaycaster component
GraphicRaycaster gr = StickUI.GetComponent<GraphicRaycaster>();
//Create the PointerEventData with null for the EventSystem
PointerEventData ped = new PointerEventData(null);
//Set required parameters, in this case, mouse position
ped.position = SpawnPos;
//Create list to receive all results
List<RaycastResult> results = new List<RaycastResult>();
//Raycast it
gr.Raycast(ped, results);```
and how do I even know if im going right way xdd

[inner folio]

its probably the event system, but im not sure what i could do otherwise, since without the event system, it doesnt get selected at all

[slender nymph]

is this AI generated code? because it is against server rules to seek help with AI generated code

[lofty lintel]

No

Its this code

from the website other guy gave me

[swift elbow]

doesnt look like it. usually ai code puts a space after each // before writing the actual comment

plus the comments would be a lot more detailed

[lofty lintel]

I just changed it up to my likes

don't know if im going the right way tho

[slender nymph]

no they wouldn't. ai code generally has those brain dead obvious comments that say exactly what the line does with no other context.

[lofty lintel]

well anyways it's not AI xd

[slender nymph]

have you considered testing it?

[lofty lintel]

yes

float minX = StickSpawn.position.x - 9f;
float maxX = StickSpawn.position.x + 9f;
float minY = StickSpawn.position.y - 1f;
float maxY = StickSpawn.position.y + 1f;
float randomXPos = UnityEngine.Random.Range(minX, maxX);
float randomYPos = UnityEngine.Random.Range(minY, maxY);
if (StickUIs.Count == 0)
{
    SpawnPos = new Vector3(randomXPos, randomYPos, 1);
}
else
{

    //Code to be place in a MonoBehaviour with a GraphicRaycaster component
    GraphicRaycaster gr = StickUI.GetComponent<GraphicRaycaster>();
    //Create the PointerEventData with null for the EventSystem
    PointerEventData ped = new PointerEventData(null);
    //Set required parameters, in this case, mouse position
    ped.position = SpawnPos;
    //Create list to receive all results
    List<RaycastResult> results = new List<RaycastResult>();
    //Raycast it
    gr.Raycast(ped, results);
    if (!gr.blockingObjects.IsUnityNull()) { Debug.Log("worked??"); }
    if (!gr.blockingMask.IsUnityNull()) { Debug.Log("worked??"); }
}
StickUIs.Add(Instantiate(StickUI, SpawnPos, Quaternion.identity, StickSpawn.parent));```

[rocky canyon]

i have a developer console in my game.. and i had to do something similar.. b/c when you pressed the HotKey to open the terminal the mouse was still locked in the center of the screen so i would have to also press Esc to unlcok the cursor and then click the input.. (so i wrote code that would focus it as soon as the terminal was pulled down..)

[lofty lintel]

This is weird effect im getting but i think its close to what I need Just don't know how to modify it

[rocky canyon]

@inner folio let me see if i cant find my code.. there may be something in there thats helpful

[inner folio]

what i'm trying to do is have computers around the map that open a terminal to teach players linux cli cmds, but the EventSystem stops them from people able to type in the input

i originally had a seperate scene for the terminal, but that didn't work since the position of objects in the main GameScene would get reset when i switched back to it

[rocky canyon]

ya, i remember i have my Event System cached into my GameManager script..

b/c i have to manually manipulate it to get my command terminal to work correctly

[inner folio]

interesting

[rocky canyon]

i'll look for it

[inner folio]

if i dont include the EventSystem, the input box doesn't get selected though which is weird lol

[rocky canyon]

ya, if its a UI element. you need a EventSystem to even interact w/ it

[slender nymph]

well yes, that's part of the event system's job. you need it because it is what makes the UI work

[inner folio]

this is also my first time using unity so im a little bit confused

i didnt have an EventSystem on my original scene for the terminal though i dont think (nvm it was in the root hierarchy)

[lofty lintel]

even weirder

(that one stick is also ui)

[inner folio]

omg

[rocky canyon]

you can see i still have a little issue with mine.. *if i dont use a command that changes the scene or something.. then when i close it i have to force my cursor back into locked mode.. by toggling my main menu

[inner folio]

i moved the EventSystem into the root hierarchy and it worked lmao

[rocky canyon]

sooo not perfect.. but it works for the first part (focusing on the input)

[rocky canyon]

ohhh soo its fixed now? 👍

[inner folio]

yeah 🔥

[rocky canyon]

cool Tux

[inner folio]

his animation is supposed to be a running animation... still havent figured animations out 😭

[rocky canyon]

ya, soo that makes sense.. the event system wasn't working correctly.. b/c it was activated along side of the terminal.

[inner folio]

ah okay

[rocky canyon]

best to have it always active before hand.

[inner folio]

that makes sense, i didnt think the original terminal scene even had one, but it did by default; i guess whoever started this scene in my group removed the EventSystem or something

[rocky canyon]

like i was saying.. i keep my event system cached.. in the game manager

always nice to have a reference to it at all times (imo)

[inner folio]

i see

[rocky canyon]

usually its not very important.. but since i swap entire UI and Canvases I have a Master event system that i carry from one scene to another

[inner folio]

it works though :D

[rocky canyon]

hey, if it aint broke dont fix it

[rocky canyon]

what is this tho?

is that running actual windows shell or something?

[inner folio]

nah it's just a virtual file system

[rocky canyon]

ohh okay.. i thought u tapped into windows command prompt or something

lol

[inner folio]

i should also probably not use C: ... > since its not windows cmds anyways lmao

[rocky canyon]

ya, the C:\WINDOWS\System32 part threw me off

[rocky canyon]

did u code this urself? or is this an asset?

https://assetstore.unity.com/packages/tools/gui/command-terminal-123344 i use this one.. pretty solid over all

[inner folio]

coded myself but watched a video for the actual UI stuff

[inner folio]

i saw this earlier after i had already made the terminal 😭

[rocky canyon]

i use this one b/c its GUI code...

its not an actual gameobject UI panel

all drawn at runtime.. i like that for whatever reason

[inner folio]

yeah

mines probably not optimized at all but i dont really care since im just trying to get this working lmao

[rocky canyon]

the one i linked is very solid.. and easy to use.. if u ever decide to change urs

my favorite part is its tied into the Console.. soo it will log debugs and stuff inside the terminal as well as the console

[inner folio]

that looks pretty nice

have you confirmed that OnTriggerEnter is actually being called

also https://unity.huh.how/character-controller/teleportation

[languid spire]

do they not have debugging in LUA?

[upper thistle]

using an if statement in the update should work to debug that right

[upper thistle]

They do

[languid spire]

then add some to your code and show the logs

[upper thistle]

Thanks man, you seem like a respectful dude

will do that

        if(other.CompareTag("Player")
        {
            // usually theres a 2nd conditional to check for specific objects
            // you don't want *any* collider to trigger the logic (usually)
            
            Debug.Log("Also here to know if the collision is the Right collision");

        // finally if it is
        thePlayer.transform.position = teleportTarget.transform.position;
        }
    }
}```

[upper thistle]

What's CompareTag?

[rocky canyon]

you could even use other.transform.position = teleportTarget.transform.position

[upper thistle]

I get other using the parameter of collider

[rocky canyon]

https://docs.unity3d.com/ScriptReference/Component.CompareTag.html

[upper thistle]

thanks

[upper thistle]

I'll write a debug log myself and check it out

[rocky canyon]

its to decide if the Tag is the tag ur expecting.. theres many different types of comparisons tho..
you could check for Tags.. u could check if its on a certain layer.. u can even use TryGet to see if it has a sepecific Script/Component

[upper thistle]

Not sure if it has that tag unless it's on it by default

I don't know how the unity tagging system works yet

[rocky canyon]

u'd assign it

[upper thistle]

I'll look into it, thanks bro

[slender nymph]

you've also seemed to have missed the actual solution to your issue

[rocky canyon]

true.. have you debugged to see if the collision is even detected yet @upper thistle

[upper thistle]

So it does trigger

[rocky canyon]

ahh, good good

[slender nymph]

that's not it

[rocky canyon]

then the collision works 👍
