[wooden star]

i did a very similar thing in another project and it worked compleatly fine

[rich adder]

did what thing ?

your TimerScript doesn't seem to exist

[wooden star]

referencing another script

[rich adder]

where is TimerScript ?

[wooden star]

yea thats what i dont get cos its litteraly right there at the top but its saying its not

[sour fulcrum]

thats not how it works

does TimeScript exist in your project

[rich adder]

referencing something that doesn't exist doesn't make sense so its telling you it doesn't exist lol

declaring a variable has nothing to do with a type existing

[sour fulcrum]

(also if it doesn't exist in your project it's certainly not going to be attatched to an object in your scene)

[rich adder]

its like you trying to use a word in autocorrect that doesnt exist in the dictionary

when you declare its just saying " I want to store a TimerScript here "
computer is saying "What is TimerScript? I have no idea"

[wooden star]

ive just checked and bothe scrips are working

[rich adder]

what is "both scripts"

we dont see your setup

[rich adder]

show TimerScript.cs

[rich adder]

see how its defined as Timer ?

the filename is completely unrelated to whats defined inside

[wooden star]

ah is it because i renamed it?

[rich adder]

yes renaming the file does nothing to whats inside

[wooden star]

i fixed 2 errors

thats the only one now

[rich adder]

you are trying to use GetComponent on an array

it would not make much sense to do so as an array has no such method

only components have GetComponent methods on them

You probably want the Singular version GetObjectWithTag not Objects

[sour fulcrum]

and GameObject

[rich adder]

also if you just want that 1 script you can just link it in the inspector no?

[wooden star]

ngl i didnt realise i said plural mb

[wooden star]

wdym im new

[rich adder]

[SerializeField] TimerScript timer

then drag n drop

https://unity.huh.how/references/serializing-component-references

you already used it for TMP I see

[wooden star]

would it still work when the timer script is linked to another game object

[rich adder]

ofcourse

as long as they are part of the same scene

other methods otherwise you can check link above it has alternatives if you have to find runtime / spawned objects or referencing a scene object from prefab

[wooden star]

ive sorted all the syntax errors but now i can get this to work

the timer reaches 0 and the character is still there

[rich adder]

these dont give much context to where this line was placed and whether or not its running

[rich adder]

you are keeping characterAlive bool track in 1 sript, and then another script, just because they share the name they are NOT the same at all

each script has its own copy of the bool

[wooden star]

is there away to make them share it

[rich adder]

several ways

[wooden star]

do i just reference the script i want the bool for before hand

if (TimerScript.characterAlive == false)?

[rich adder]

the cleanest way would be to reference the timer script and only follow the timer from there

[rich adder]

a timer shouldn't really care or track a characterAliveBool

the timer is only a timer, thats all it should do..track the time

if the player cares about the timer going to 0 then you follow the currentTime from the player

and logic from there

[wooden star]

i have it so when the timer runs down to 0 it kills the characted

[rich adder]

mhm I understand what the usecase is

[wooden star]

but if theres another way for it to do the exact same thing?

[rich adder]

what do you mean , i just told you how

track the value of currentTime there or use a bool from timer

eg
if(timerScript.isTimerOver)
//do stuff

ideally you use events but here its okay to use Update since you're new

so you switch up the bool in the TimerScript from characterAlive to IsTimerOver or whatever

then in player update you check the value

[wooden star]

so scripts share data types exept bool?

[rich adder]

scripts only share something public when you access it

they are not global values or anything

thats why you have to make a reference to it

the datatype is irrelevant

[wooden star]

i think what im strugaling with is my lack of knowlege on referencing

This is another project where i tried the same thing and it worked

But it doesent work here

[slender nymph]

because in the first one you are using a variable that happened to have the same name as the class. the second you are just directly using the class instead of your variable

you should consider stopping what you are doing and go through the beginner c# courses pinned in this channel to get a better grasp of the basics instead of trying to brute force it

[wintry quarry]

<access modifier> <class name> <variable name>

And note you are using JumboJoe in the code, not JoeScript:

this is correct, you are using the variable name correctly.

In the other one, you are trying to use the type name.

[fading barn]

do i need to multiply my force vector which i am passing in rigidbody.addforce method by time.deltatime if the function is being called in fixed update?

[slender nymph]

no, you should not be multiplying your forces by deltaTime. The forcemode you choose will take that into account if necessary

and you should also never be adding force in Update with the exception of one-off forces, they should always be done in FixedUpdate to ensure they are consistent (especially considering the rigidbody is only ever updated on FixedUpdate frames anyway)

[prime goblet]

i'm handling a groundcheck using this method, however it ALWAYS returns false! (like the player is in the air)

            if (_jumpAction.WasPressedThisFrame()) {
                if (Physics.SphereCast(groundCheck.position, 0.5f, Vector3.down, out RaycastHit hit, 0.5f, playerLayer)) {
                    rb.linearVelocity = new Vector3(rb.linearVelocity.x, jumpForce, rb.linearVelocity.z);
                }
            }

edit i solved it by using checksphere!

#💻┃unity-talk

[sleek flare]

Thank you, I'll move it there.

[unique olive]

Hello not sure if this is the right place to ask but
I have a question on how to keep on track of the scripts you make,
are there any good standards on how to make memos of how each scripts connects and works?

cuz I have like 10 C# scripts in my projects & it's getting hard to get back on track whenever I come back after a break

[prime goblet]

sort them in folders

however you like

here's an example of mine, but it's always up to your preference

[eternal needle]

What is playerLayer and is the ground on that layer?

[prime goblet]

yes, i already fixed the issue

i decided to use CheckSphere instead

[eternal needle]

Ah it was edited as I hit enter

[prime goblet]

oof but thanks anyway

[ivory bobcat]

if (_jumpAction.WasPressedThisFrame()) {
    Debug.Log($"Jump was pressed", this);
    if (Physics.SphereCast(groundCheck.position, 0.5f, Vector3.down, out RaycastHit hit, 0.5f, playerLayer)) {
        rb.linearVelocity = new Vector3(rb.linearVelocity.x, jumpForce, rb.linearVelocity.z);
        Debug.Log($"Character had jump", this);
    }
}```

[prime goblet]

            bool isGrounded = Physics.CheckSphere(groundCheck.position, 0.5f, mask);

            if (_jumpAction.WasPressedThisFrame() && isGrounded) {
                rb.linearVelocity = new Vector3(rb.linearVelocity.x, jumpForce, rb.linearVelocity.z);
            }

this was my new solution (yes i know i can put it directly into the statement but i reuse it directly after)

[eternal needle]

I wouldnt really use that for ground checking logic honestly. Unless you're confident this is as far as you'll need, and not deal with stuff like jumping because a wall is beside you

[prime goblet]

nope, it's literally a walk around the place game

[eternal needle]

I meant that because your current logic would let you jump if there was a wall beside you

Theres no way of checking what the slope of the ground is here

[unique olive]

Actually I meant like how to keep a document on how the script works
like ex.)EnemyManager: Spawns 1 enemy every 10 sec + Calls someGameObject,
PlayerHP: Spawns HP UI, if hp0 = play animator "dead"

All that kind of information, I was wondering if there's an easy way to keep a memo of all of em/or
like make it easy to read for other devs to get in the project too

[prime goblet]

comments

// or /* */ for comment blocks

/*
* HEADER
* this code does x
* this code does y
* changing z modifies w
*/```

[prime goblet]

true

i added your log statements to my original problematic code, it knows jump was pressed but never acknowledged the player's ability to jump

[eternal needle]

You would usually organize the code into folders already to what topic its solving. Thatd narrow down a lot for other devs. Comments like this could go at the top of the class or above the relevant method names but the examples you gave would probably be unnecessary comments.

[prime goblet]

this ^^, if your code is readable enough developers will quite likely just understand it from the get-go

[eternal needle]

Usually your files shouldnt be that large, so it wouldnt really take much for a dev to skim through it and have a basic idea of what it's doing. Comments are there to explain what isnt easily understood. Code should be written in a way in that its understood immediately

And when organizing the code into folders based on what its solving, there wont be that many classes to go through and understand.

There isnt really a built in tool otherwise to solve what you're describing if you're trying to get a dev caught up on the whole project. Youd likely just want to make some basic diagram

[sour fulcrum]

draw.io or something can be nice for that

[unique olive]

I'll take a more look on how to sort my folders, I did sort them in a few genres like GamePlay/UI/etc but seems like I could go more deep on sorting them out

[prime goblet]

they aren't trying to make a flowchart, they are just explaining the purpose of each script

[sour fulcrum]

my message was an extension of bawsi's

[unique olive]

Actually draw.io was something I was expecting lol but I learned we didn't really use flowcharts

Thank you all so much

[eternal needle]

A diagram doesn't necessarily mean flowchart. A flowchart would be more to describe a complex process. It could even just be a class diagram or whatever software eng nerds call it these days, where you just show how classes are linked.

[eternal needle]

GamePlay would be a bit too vague for sure. I would split it up much more. Like movement in it's own folder, hp/stats stuff in another

[sour fulcrum]

Not sure if this helps at all but a misc. diagram ive made in the past to visualise that kinda thing

i had nicer looking ones somewhere but they have poofed

kinda cooked but was semi helpful too

[unique olive]

So then
Class diagrams = See how everything is linked (mainly in complex stuff
Code explanation = comments and sorting them more specific
I'm still a noob dev didn't know how everyone sorts it out

[unique olive]

That's looks super helpful omg ty

[sour fulcrum]

Ideally a majority of code is written in a way that makes comments unneccasary

Depends what it is though

A lot of the time a comment can be really handy if you decided to do something a certain way because another way did not work and your comment explains that your not doing it that way because of whatever reason

[unique olive]

don't punch me but I've been learning code through unity's tutorials until I came across Claude's ai code gen
which made reading/understanding all codes a pain in the neck

not knowing this really feels like ai is rather making it hard to code either way

[sour fulcrum]

no ones gonna crucify you for using AI but you can't ask for help with ai code on this server and most active members strongly believe it harms in learning rather than helping

[unique olive]

I believe you're right, cause the mindset is starting to be learning code → make the code done(which is tough to do without learning) after using ai, its no easy way through

[naive pawn]

ai makes half-baked stuff for you at the cost of you not learning how to make it yourself, or any of the other relevant skills (researching info, understanding docs, debugging, reading & tracing errors, project architecture, separation of concerns, breaking up a problem, etc...)

[prime goblet]

it's not against the rules unless you havent tested it or noted such but it's a hrorible idea

[rich scroll]

Its not. People have this perception of AI cause a lot of other people use it the wrong way: To do what they want, without thinking about what its doing and then taking it for granted.

I regularly use AI to help me understand a topic better, then I go and check if its correct. To generate code, but then I go and try to understand why it generated that specific code and if it has problems or not. And so on

The problem is not with AI, its usually the users

[naive pawn]

but why not just skip the middleman and go to known reputable sources lol

[rich scroll]

Cause sometimes the source doesnt explain it the way an AI can

[naive pawn]

The problem is not with AI, its usually the users
true, but it's much harder to instruct people to "use it efficiently" lol
genAI is just very inconsistent

basically, it's a beginner trap

it has its uses, but it's much, much more likely to be misused, whether intentional or not

[rich scroll]

Have you ever looked into the unity docs? Half of it feels like noone actually cared about it and literally just wrote down what the arguments to a function are, and didnt provide any examples

[naive pawn]

and chatbots are using that same documentation. if an example isn't given, it'll just make one up, whether it's valid or not lol

you don't actually gain anything by using a chatbot

[rich scroll]

Thats why I then go and check if that example is correct

And why its correct

[naive pawn]

how do you check it if there's no example?

there are examples, just not in the unity docs; so again, just skip the middleman and go to those lol

[rich scroll]

The ai gives an example, which I can then try out and figure out what its doing

[naive pawn]

you're just creating more work for yourself 😆

[rich scroll]

Yeah, cause finding a source is as easy as that

Sometimes its not

[naive pawn]

it is, really

this topic has been exercised to death already, the concensus isn't going to change

[rich scroll]

Im not trying to change it

[naive pawn]

the recommendation to beginners will stay the same: don't use chatbots, you just end up stunting your learning experience

chatbots are a tool, one that you need experience to navigate and use correctly

beginners, by definition, don't have that experience

[rich scroll]

And thats what we should tell the beginners

How to use it

[naive pawn]

if you advocate using chatbots to beginners, you are actively hurting them

[rich scroll]

Not just dont use it its bad

[naive pawn]

orrrr, just skip the unnecessary step and just learn the actual relevant topics yourself lol

you just add another unnecessary step 😆

and that interrupts the actual useful learning

[hexed terrace]

It's not the 'how to' that's the main issue - it's that "ai" will give incorrect code, and beginners don't have the knowledge to know what's wrong, won't understand it, and won't learn anything about coding.

[rich scroll]

I don't think it does, if you know how to use it. But if everyone is telling you to never even touch it, you'll never know how to use it. Like you said, its a tool. Tools can be super useful, but it has to be learned, just like the 'actual relevant topic' has to be learned.

I'm on the train with you all, that it shouldn't be the first thing to go to

but if you never even try it cause everyone is saying its bad, you'll never know how to use it properly

[naive pawn]

does one have to know how to use it properly? what is it even good for lol

i digress

it's just not a tool for beginners

it shouldn't be learnt alongside the other skills

you need to already have those other skills to be able to filter through all the bullshit it will spawn

[rich scroll]

that's for everyone to find out themselves

I personally find it really useful for small things

[naive pawn]

it is, objectively, a harmful tool when learning

[hexed terrace]

by time you're at a level of knowledge to be experienced enough for ai to be... ok to use... you're no longer a beginner.

[naive pawn]

it's a masquerade of a source of truth

so to put it bluntly; sure, maybe genai has a place. but it absolutely does not have a place here, in #💻┃code-beginner

[rich scroll]

I never said its good for leaning. I just said its not a bad tool if you know how to use it

[naive pawn]

and if you know how to use it, you aren't in the learning stage

[rich scroll]

eh, yea thats probably true

[naive pawn]

just to make sure we're on the same page; the issue is not the question of learning to use genai, the issue is about beginners learning to use genai

[rich scroll]

I know, but I still wouldn't 'scare' beginners into never using it cause it's bad. I'd say use it when you know more

[naive pawn]

it is, still, pretty bad as a source of truth anyways

[rich scroll]

depends on what you want it to do

[naive pawn]

"when you know more" to a beginner would just be the next day lol

[rich scroll]

I know

I just didn't want to write a whole list of things to know

[naive pawn]

anyways another point; you have to have a certain level of experience in general to be able to handle the output
you should see the absolute pain it is to deal with people who use that shit and are surprised when it doesn't work lol

it's just much easier for us, the community, and the learner, a beginner, to just stay away from genai

don't give a benchmark for them to start using ai lol

[rich scroll]

oh yea I know, its mainly the younger people

[naive pawn]

it'll backfire to hell

[rich scroll]

I'm not giving them a benchmark

[naive pawn]

anyways still; recommending genai in any capacity in a support space just isn't going to be productive for anyone involved

[abstract copper]

Getting the error MissingMethodException: Method 'PlayerController.OnMove' not found. When using the new input system

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

I have this method in a script on the same gameobject that has the player input component and the component has behavior it send messages, i checked the action and map name both are correct.

[naive pawn]

sendmessages doesn't emit a InputAction.CallbackContext, it emits a InputValue

[rich scroll]

yea, either change the sendmessages to Unity events, or the arguments to InputValue

[naive pawn]

so you'd need to have something like this instead

public void OnMove(InputValue val) {
  moveInput = val.Get<Vector2>();
}

[abstract copper]

Oh lol thanks, first time using it even tho i should have long time ago

[hollow wraith]

Any recommendations to fix an issue with my jittery camera?
I think the issue is that the player position changes, which messes with the camera's movement speed to catch up with the player, but I'm not entirely sure how to address that as an issue.

[wintry quarry]

Does the player have a Rigidbody?

Also please share code via !code

The player does have a rigid body yeah

[wintry quarry]

You need to turn on interpolation for the player's Rigidbody

And you need to make sure it's moving and rotating only via the Rigidbody, never the Transform

[hollow wraith]

Oh it's immediately 100x better thank you so much.

I'll change up the code so it works with Rigidbody over Transform

[honest haven]

Having a issue with a button i have private IEnumerator SetSpinButtonSelectedNextFrame() { yield return null; // wait 1 frame EventSystem.current.SetSelectedGameObject(null); EventSystem.current.SetSelectedGameObject(spinButtonTenCoinsGameObject); Debug.Log("Selected GameObject: " + EventSystem.current.currentSelectedGameObject?.name); } to set the current selected button as highlight. the console shows the button as current select gameobject like so . but the sprite swap is not working and if i press enter it does not work. So what would stop this from working

[naive pawn]

doesn't sound like a code issue, perhaps #📲┃ui-ux or #🖱️┃input-system?

[dry pulsar]

So i am doing that script:

But it wont work with "Random"

[naive pawn]

hover over the error and see what it says

[wintry quarry]

Change it to UnityEngine.Random

[naive pawn]

so does that make sense to you

just remove the using System; at the top

[wintry quarry]

Or that

[dry pulsar]

Ty guys

[noble cedar]

guys could someone help me how do you create JSON using code and also encrypt it so players cant modify it

[brave compass]

You can do this one step at a time. Just figure out how to save data to a JSON file first, then after that you can figure out how to encrypt a file.

[noble cedar]

I know how to add data to .txt file meaning .json wouldnt be different

[wintry quarry]

there's no way to encrypt a json file on a player's computer such that they can't modify it

[noble cedar]

I believe

[wintry quarry]

Worst case scenario they can just use Cheat Engine or similar to modify the data in memory

If you want the data to not be modifiable by the player it can't live on their computer, you would need to store it in the cloud

[noble cedar]

yea but I also want that players would save progress offline

[wintry quarry]

then you have to accept that the players will be able to modify it

which isn't a problem

[noble cedar]

wait you cant encrypt it at all or just there are tools to bypass that

[wintry quarry]

nobody cares if someone cheats at solitaire

[wintry quarry]

If you want your game to be able to read the encrypted file the game would have to include the encryption key

which defeats the purpose

[noble cedar]

I mean its similar game to COD zombies so I believe people wouldd care if someone cheated tho the only way they could cheat is unlocking guns and unlocking whole upgrade tree xD

[wintry quarry]

that is an online game

and progress is stored online

(i think, i never played it)

assuming it's online multiplayer

[noble cedar]

you can also play it single player and that doesnt require internet

[wintry quarry]

but your progress is still stored in the cloud

[noble cedar]

but the progress stays even when you are offline so they must use something else then cloud

[wintry quarry]

they use a hybrid approach no doubt

[noble cedar]

like both database and JSON?

[wintry quarry]

almost certainly not json

probably a custom binary format

but JSON is really irrelevant to the discussion

it's just a data format

it's orthogonal to the discussion of where the data is stored and if and how it's encrypted

[noble cedar]

would you mind speaking in simple english please I am not really good at it

[wintry quarry]

orthogonal == "irrelevant"

not directly applicable

a different discussion

[noble cedar]

so what would you recommend me using to store player data? if I want to have database and offline storing?

[wintry quarry]

basically just a local save file of some kind that gets synced to the cloud and gets validated by your server if and when it gets synced to the cloud

as for how validation works (i.e. "was this earned legitimately") that's a pretty hard problem in and of itself

[exotic hazel]

Every cube is a chunk and the code is spawning 10 chunks whereas i have set the value to 5. could someone pls help
https://paste.ofcode.org/gmvqpD3ZSy7VfFw37DnwPY

[noble cedar]

I feel like i found how to make validation

[exotic hazel]

pl help

[wintry quarry]

Double check the number you have set in the inspector

[noble cedar]

@wintry quarry what if I made like that by each update the storage would get version up and if the version stays the same but values change in database and the file where the data is stored then players would get banned idk for 1week for playing with files

[exotic hazel]

o m g. i spent 1 hr js to seeAAAAAAAAA

[noble cedar]

average thing of unity developer xD

[obsidian holly]

heeyy (idk if i put this here but honestly im desperate, just lmk if im wrong) so as i am a beginner, i made a game over the course of 4ish weeks.. (its 2D and bad) but the point was to use it for my study in one of my classes (so it doesn't have to be like expert level or anything). issue: it works perfectly fine when in Unity (ykn) and I published it to several different (free) websites to try to make it into an actual web browser game. I wish I knew what question to ask but im just confused at what the issue is... i've researched and researched, so I guess I need help with the publishing aspect and how I can actually make it into a 2D web-browser game? (I can explain more if someone helps, its a whole thing)

[drifting vale]

you mean publishing and then having it public so other people can play it?
Continue with your current message that you're typing and then react to this xD

[wintry quarry]

You'd have to explain what goes wrong in the build

[obsidian holly]

its so hard, let me try

[exotic hazel]

another thing. the inspector is correct but when i run the game it becomes like this. and i dont understand why

2nd image is how it becomes

[wintry quarry]

Do you have a custom editor for this script?

[obsidian holly]

explanationish: in unity, my game runs pretty fine when I test, no errors come up, seems as the title screen works + my instructions screen (for the study), my buttons are clickable, and the score works perfectly fine. so, after, what I did was I made my game into that web browser build, I seem to have a correct scene list to my understanding, then i have the zip file which I put into several websites (that are free, so unfortunately its itch.io and game something i forget), and I put in the correct file+ stuff for it to be a browser only type game.. now, when I open the game in my browser, it wants to play, but I am met with a blue screen and only one of my UI is working (which happens to be the round UI so it says "round 1/4") and it stays there, nothing happens-- no title screen/instruction screen. I occasionaly see my button (that the people can click) pop up but its one and stops.

[exotic hazel]

nope

or not that i know of

[wintry quarry]

You need to do this with a development build and check the browser console for errors

[wintry quarry]

No idea then, seems like a Unity bug. Try restarting and/or upgrading?

[obsidian holly]

I guess? thats my best at trying to explain ^, my troubleshooting was going through different settings in player other settings, trying to change a camera to see if one of the UIs was stuck? or like trying to find why the UI's aren't working? idk not sure

[drifting vale]

This would be good to see what errors the build has on webGL, do this first, see whats happening.

[exotic hazel]

its been 2 days i thought of looking on it after i perfect the script

so restarting wont work

[obsidian holly]

how are you getting the WebGL thing? mine just says web

I was thinking it doesnt matter too much if it was just named web?

[drifting vale]

could be a diff unity version, I am on 2022

[obsidian holly]

also, is this photo from build profiles?

[drifting vale]

Its a screenshot from my Build Settings tab

File>Build Settings

[obsidian holly]

that was another thing I saw to troubleshoot but I only have build profiles and to my understanding thats the same thing as build settings?

when i click file*

[drifting vale]

ah I see, has been renamed I guess, Ill create an unity6 project rq to see whats there

[obsidian holly]

ohh I see what you are talking about, development build at the bottom. I should click that and see the errors? (where would I see the errors also?)

(ive been troubleshooting for hours im buffering lol)

[drifting vale]

Yeah, enable that box, then make an new build and try running that. Then whenever you go to your browsers console and see what errors you get. I have not used the Dev mode on a web build myself yet, so I wont know wxactly what I would look for.

[wintry quarry]

As mentioned, in the console window of your browser

[drifting vale]

console: ctrl+shift+c / ctrl+shift+i most of the time

[obsidian holly]

my games taking forever to build for some reason lol but yea ill do this

[shut swallow]

https://paste.mod.gg/hgcamwazgoek/0
I'm not sure why, but it seems gravity is not applying properly, could anyone have a look at this?

It's probably some indenting problem because it worked before

[obsidian holly]

okay, well the only error i got is WebGL: INVALID_ENUM: getInternalformatParameter: invalid internalformat so 😭

[quick pollen]

how can you interpret this formula in unity?

        float g = Physics.gravity.y;
        float v = 45;
        float d = Vector3.Distance(transform.position, targetPosition);
        angle = 45 + 1f/2*(float)Mathf.Acos(g*d/(v*v));```
this is my attempt at it, but it doesn't work

(this is the formula for the angle of reach at which a projectile must be launched in order to go a distance d, given the initial velocity v.)

I'm basically trying to create a mortar

[wintry quarry]

Acos returns a value in radians in Unity's API

You need to convert it to degrees

[quick pollen]

oh

shit

that makes more sense

I was given values between like 0 to 1

well not exactly but yea

[quick pollen]

is there a built in function for that?

[wintry quarry]

Math.Rad2Deg is the constant to multiply by

[quick pollen]

oh theres Rad2Deg yea

[quick pollen]

multiply? isnt it a function?

[wintry quarry]

Nope

[shut swallow]

it's just 180/pi

[wintry quarry]

It's just a number

[shut swallow]

between rad and deg

[quick pollen]

also, how can I calculate the minimum velocity required to hit a point?

I couldn't find a formula for that

[shut swallow]

nvm it is an bracket error lol

[shut swallow]

in 2d?

[quick pollen]

yes I suppose

I mean

the mortar will always be looking toward the enemy

so I can ignore the Z variable

[shut swallow]

man i just learnt this not long ago

gimme a sec

[shut swallow]

lemme check notes

[quick pollen]

I'm also having issues actually like

rotating the object

the red ball on the cube is meant to indicate which way is forward

but rn it just does this

transform.rotation = initialRotation * Quaternion.Euler(new Vector3(angle, 0f, 0f));

o shit actually it works

I just needed to subtract 180 degrees from it

[shut swallow]

@quick pollen

since the cannon is always facing the object you can do this

and if you need to find the distance you can do Vector3.Distance

i assume that the angle of the cannon is fixed right?

btw u is the velocity, |u| is the magnitude of the velocity

but it shouldn't matter since u should be positive anyways

Oh yea I should remind you

This angle is in radians iirc

also one more thing

this equation breaks when there is a differance in y level between the two objects

[quick pollen]

its not?

[shut swallow]

well

that's complicates things a bit

[quick pollen]

I mean

I'd need both the speed and angle to be variable

and I always want the steepest angle and lowest velocity

[shut swallow]

alright

[quick pollen]

I already have the formula for the steepest angle

but I need to be able to calculate the velocity beforehand

[shut swallow]

so before you know the angle or after

if after you know the angle

you can just plug the angle in the equation I just gave out

that returns minimum velocity

[quick pollen]

wish it was that easy

i need it before

[shut swallow]

alright

[quick pollen]

tho wait

[shut swallow]

classic hs math

[quick pollen]

technically I can just plug in the distance as the speed?

I mean

[shut swallow]

that doesn't work in projectile motion

[quick pollen]

it would guarantee a possible angle, no?

[shut swallow]

yes?

[quick pollen]

i think thatd be fine

[shut swallow]

if you like shoot directly at it, sure

but like if you shoot at an angle

[quick pollen]

I updated the formula 45 + 1f/2*(Mathf.Rad2Deg * Mathf.Acos(g/d))

instead of g*d/v*v I substituted v for d

[shut swallow]

it wouldn't work if you're looking for steepest angle and slowest velocity

[quick pollen]

simplified the d next to the g

and it works fine

[shut swallow]

ight then

lmfao

[quick pollen]

I guess it doesnt matter THAT much

what matters is that its guaranteed to hit, and doesnt try to fire in a straight line

[shut swallow]

lmfao

i mean yea that works

[quick pollen]

now I need to find a way to also make it look towards the player

[naive pawn]

if you optimize for slowest velocity it'd be 45°

[quick pollen]

the mortar, i mean

[naive pawn]

that's the angle for which you get maximal distance for a given speed

[shut swallow]

oh yea i forgot about that

thanks

[quick pollen]

transform.rotation = initialRotation * Quaternion.Euler(new Vector3(angle - 180, 0f, 0f));

right now I do this

but I need to make sure it looks towards the player

theres Quaternion.LookRotation, yes

[naive pawn]

i meant to reply to #💻┃code-beginner message here, sorry
@quick pollen

[quick pollen]

but I only want to change the y and z rotation

[quick pollen]

I thought so, yeah

I mean, honestly it doesnt matter too much

as I said, I just wanted to avoid cases where the projectile either flies for wayyy too long, or is aimed directly at the player

using the distance made it so it takes more time to get there depending on how far you are

[naive pawn]

maybe this doesn't really apply, but the direct solution i can think of is just having 2 nested GOs
the parent represents the mortar as a whole, and rotates about y to point towards the player
the child represents the barrel, and rotates about x to angle the barrel up

[quick pollen]

actually, not too bad of an idea

lemme test that

[shut swallow]

I'm thinking of getting the angle difference between the mortor and player

[quick pollen]

that exists, yes

[naive pawn]

and yeah i think it'd use this for the Y rotation at least

[quick pollen]

but that doesnt sound like it

[quick pollen]

thats the only thing id need to change

but idk how

I only need the Y angle from the lookrotation

I guess i can convert to eulerangles and take it from there?

[naive pawn]

transform.rotation = Quaternion.LookRotation(Vector3.ProjectOnPlane(target.position, transform.up))?

wait i don't think that's how ProjectOnPlane works one sec

[quick pollen]

im trying smth else wait

I tried this float playerAngle = Quaternion.LookRotation(targetPosition - transform.position).eulerAngles.y;

not great

transform.rotation = initialRotation * Quaternion.Euler(new Vector3(angle - 180, playerDirection, 0f));

[naive pawn]

i mean you're working directly from rotations to rotations

why go through eulerangles and back

[quick pollen]

for the LookRotation?

o wait you're right

transform.rotation = initialRotation * Quaternion.Euler(new Vector3(angle - 180, playerDirection + 90, 0f));
this works tho

actually i can get rid of the 90 and 180

[naive pawn]

Vector3 target = player.transform.position;
target.y = transform.position.y;
transform.rotation = Quaternion.LookRotation(target);

[quick pollen]

I just need to change the initialrotation

[naive pawn]

this would work fine, i think

[naive pawn]

ProjectOnPlane might give a way to do it in one line, but maybe that gets convoluted

[quick pollen]

but I also need it to be angled

so it both looks toward the player and is also angled so if a projectile is fired, it hits the player

[naive pawn]

im going off of this, where you would have a separate y and x rotation

so this would just be the y rotation

and then you'd compute the x rotation with trig on the other GO

or i guess if you have a single object and (for example) just make it point up 45°, could do something like

Vector3 target = player.transform.position;
target.y = transform.position.y;
transform.rotation = Quaternion.LookRotation(target) * Quaternion.Euler(45, 0, 0);

[quick pollen]

that does look tidier, lemme test that

also, how could I go about making it so something is always looking in a specific direction, regardless of its parent?

as an example, make something always look towards exactly down, without caring about the parent?

[quick pollen]

btw this isnt correct

[naive pawn]

set its rotation in LateUpdate, i guess?

[quick pollen]

target is a position, not a direction

[shut swallow]

can't you just set rotation?

[quick pollen]

you need to do targetPosition - transform.position

[quick pollen]

i didnt want to use code

i wonder if theres a way to do it without code

with like a constraint

[naive pawn]

oh whoops, goes to show how familiar i am with Quaternion lol

[quick pollen]

I mean, this is vector math, but its okay

you've already helped a lot

[shut swallow]

expose the argument in a script [SerializedField, Range(0f, 1f)] private Quaternion setRotation and then apply the rotation on start?

then you can just edit that rotation in editor

[naive pawn]

though FromToRotation does take 2 positions, could use that ig
so either:

Vector3 direction = player.transform.position - transform.position;
direction.y = 0;
transform.rotation = Quaternion.LookRotation(direction) * Quaternion.Euler(45, 0, 0);
```or```ts
Vector3 target = player.transform.position;
target.y = transform.position.y;
transform.rotation = Quaternion.FromToRotation(target, transform.position) * Quaternion.Euler(45, 0, 0);

[shut swallow]

is it dynamic is my question

[naive pawn]

does Range even work there?

[shut swallow]

oh yea

it's rotation

but should still be able to edit it no?

gimme a sec lemme try sth out

[naive pawn]

i mean the API lol, i confused myself about what it wanted

[slender nymph]

#📲┃ui-ux

[naive pawn]

i don't think so

[kindred iron]

oh didnt see mb

[naive pawn]

oh wait hold on, the serialization rules thing isn't an exhaustive list

[shut swallow]

you can expose it with [SerializeField] private Quaternion rotationSet

[quick pollen]

I think I figured it out

[shut swallow]

and then you can set the rotation

in code but only need to be called once

and you can edit your values in editor

[shut swallow]

the projectiles linger a bit after they hit the ground

[quick pollen]

thats okay

I just forgot to make them disappear on impact

[shut swallow]

and the mortor rotation looked a bit off

but looks fine

[quick pollen]

it looks a bit weird, yes

[small sparrow]

!cs

[quick pollen]

but it seems to do it normally

I would kinda like to make it so it goes faster and falls faster too tho

I guess I can double the gravity

no that doesnt work

if I go too close it just breaks

I get a negative sqrt

[jolly stag]

Hello, I was wondering if I could get a bit of help with some code. I'm trying to get a trigger to activate when the player goes into it and holds the space bar. I unfortunately can't see what I'm doing wrong. Thanks!
' private void OnTriggerEnter(Collider other) { if (other.CompareTag("Mantle") && Input.GetKey(KeyCode.Space)) { mantleCheck = true; } }

[quick pollen]

OnTriggerEnter gets called only once

when you enter the trigger

oh wait

are you sure that the collision is actually registered?

you should debug that first

[polar acorn]

This would trigger if you're holding down the space button before you make contact, and then contact the trigger while still holding space

[quick pollen]

how can I make an object fall faster?

changing the mass doesnt seem to change anything

[jolly stag]

So I'd need OnTriggerStay?

[jolly stag]

The code works fine so long as it dosn't the spacebar condition

[naive pawn]

did you forget middle school physics

[quick pollen]

what digiholic said, thisd work if you are holding it down while entering, not after you entered

[quick pollen]

yes

[naive pawn]

fall time isn't affected by mass

[shut swallow]

lmfao

[quick pollen]

what is it affected by then? surface?

[jolly stag]

I just gave that ago to debug it and did not seem to have any luck getting it to trigger still (Never mind it's now triggering just as I posted this -.- )

[quick pollen]

no thats not right

[shut swallow]

gravity and inital velocity

which includes angle

[quick pollen]

i thought heavier objects fall faster than lighter ones?

[shut swallow]

no

[polar acorn]

No, gravity is constant

[shut swallow]

v = u + at

[quick pollen]

man im tired lmao

[jolly stag]

Thank you @quick pollen and @polar acorn you're life savers for newbies <3

[shut swallow]

velocity is independent from mass

[quick pollen]

how could I make it fall faster then?

[polar acorn]

Mass affects terminal velocity, but not acceleration

[polar acorn]

Add force down

[shut swallow]

acceration which is gravity

[naive pawn]

the forces involved - gravity and drag
the force of gravity is proportional to mass, so it stays a constant acceleration
drag is proportional to velocity squared and the cross-section (though in unity these aren't considered, it's also just a constant deceleration)

[quick pollen]

but then my calculations for the trajectory get fucked

[polar acorn]

Well, yeah. If you're computing trajectory assuming normal gravity, changing gravity is going to change those

[shut swallow]

ignore drag for now ig, it's negligible currently

[quick pollen]

yeah drag would also make it slow down on the x axis

not just the y

[shut swallow]

you either AddForce or just adjust the gravity variable imo

[quick pollen]

as I said, I tried doubling the gravitational constant

but it messes things up

[shut swallow]

what's your eqn

[quick pollen]

if I get too close, I get a negative square root

[shut swallow]

this right?

[quick pollen]

angle = 45 + 1f/2*(Mathf.Rad2Deg * Mathf.Acos(g/d));

[quick pollen]

I changed velocity to be the distance

which is kinda stupid, but it semi works

[naive pawn]

where's the square root

[quick pollen]

idk but it seems to be mad about a negative sqrtmagnitude

[naive pawn]

distance is linearly proportional to speed, so.. sure, i guess?

[naive pawn]

that is square magnitude, not squareroot

[quick pollen]

oh

whoops

[naive pawn]

it's about something not being normalized

-# where is the "negative" part from lol

[shut swallow]

i think it's because of the acos function

normally when we do acos, we take domain 0, 2pi no?

[naive pawn]

which line are you getting this from

[quick pollen]

idk lmao, I guessed smth with the acos function too

[quick pollen]

transform.rotation = Quaternion.Euler(new Vector3(angle - 180, playerDirection, 0f));

[naive pawn]

no

[quick pollen]

I know it has nothing to do with playerDirection

this was an issue before I added that

[shut swallow]

I mean -1, 1 mb

[naive pawn]

acos would have domain [1, -1] and range [0, pi]

[naive pawn]

oh yeah true

[quick pollen]

yeah

so whats the issue I wonder

oh I mean

I know what the issue is

[naive pawn]

(why the new Vector3 though lol)

[quick pollen]

g/d is not between that

[shut swallow]

lemme look at acos in unity

[quick pollen]

needed one to use both the angle and the playerDirection

playerDirection is a float

which is a kinda misleading name now that i think about it

[naive pawn]

no you don't

[shut swallow]

yea i just checked

[quick pollen]

I tried your method with multiplying the 2 quaternions

but it was always off

it never hit the player

[naive pawn]

uhh that's not what i mean

Quaternion.Euler has an overload for float x, float y, float z

[quick pollen]

oh?

[naive pawn]

so you can do Euler(angle - 180, playerDirection, 0)

[quick pollen]

dang, didnt know that

thanks

I always assumed it only had Vector3

[quick pollen]

real useful lmao

[naive pawn]

a lot of functions have that kind of thing

[naive pawn]

uniform api surface 👍

[shut swallow]

yea acos domain is -1,1

which ig g/d breaks

[naive pawn]

wtf

[shut swallow]

when g is large enough

[naive pawn]

why are they different

[quick pollen]

so for some reason g is too large yeah

[quick pollen]

weird programming

[shut swallow]

it's 180/pi and pi/180

[naive pawn]

why is one a calculation and the other hardcoded

[quick pollen]

thats just 180 / 3.14 yeah

[shut swallow]

idk

[quick pollen]

unity ✨

[polar acorn]

Probably floating point shenanigans

Hard-coding that one probably gives a more precise answer than letting the division do it

[naive pawn]

love it

[shut swallow]

i think bc unity spits out angles in rad normally so they use a set value

[polar acorn]

Remember: Floats are significantly more dense near 0.

[quick pollen]

anyway, back onto the calculation thing, so its 100% that i cant use the distance for calculating the velocity

[polar acorn]

pi / 180 is in the range of "there's a lot of numbers here to use"
180 / pi is not

[quick pollen]

but idk what I could actually use

[shut swallow]

you can but like it's classic high school vector decomp calculations

[naive pawn]

ah, of course.

[quick pollen]

but the problem seems to be with the fact that I'm outside the domain of acos?

[shut swallow]

yes

that is the main problem

[quick pollen]

so idk what you mean by vector decomp calculations

[shut swallow]

when you solve projectile motion, you solve for the original vector by decomposing the x and y vectors given the range

and vice versa

[quick pollen]

yeah...?

[naive pawn]

give me a sec

[shut swallow]

which is a bit tedious to say the least

[quick pollen]

yeah im a bit confused lmao

I just wanna make it so the time it takes to reach the player is linear with the distance

[naive pawn]

ok so that's proportional to the velocity but it's not equal

that would take into account the angle

[quick pollen]

yeah

i mean

angle no

only distance

[naive pawn]

it would, yes

it would take into account the angle

[shut swallow]

t = 2u sin theta/g

if you're looking for the time

[quick pollen]

i mean, i dont need the time specifically

[naive pawn]

ah

[quick pollen]

what I mean is

I want to make it, so if you are x distance from the enemy, the projectile reaches you in x * y amount of time

[naive pawn]

ok what exactly are the variables in this scenario?

[shut swallow]

yea im also confused af

[naive pawn]

as in, what can you change

[quick pollen]

basically guarantee that the player is always hittable

[naive pawn]

you want t to stay constant over s

what can change, v and a?
presumably g stays constant, right?

[quick pollen]

I can change g I guess, thats it

[naive pawn]

what

no

between each shot

[quick pollen]

I mean

oh

the angle and the velocity

[shut swallow]

should be v and angle

yea

[quick pollen]

and the velocity is proportional to the distance

[naive pawn]

uh no

[quick pollen]

sorry

[naive pawn]

ah

[quick pollen]

problem is

[naive pawn]

yeah that comes with time being constant

[quick pollen]

if the distance is too low, then I acos breaks

because velocity also becomes too low

a.k.a. it cant find an angle at which is reaches it, because the projectile falls to the ground too fast

if it worked like this, itd be perfect, but as you can see, if i get even slightly close, it doesnt work

[shut swallow]

I mean like Chris said before you can just let angle = 45°

Or pi/2 radians

[naive pawn]

or just set some other constant

that makes it a lot easier

[quick pollen]

for the angle?

[naive pawn]

for a mortar that might be 60°

[quick pollen]

ohh wait

I get it

[shut swallow]

then now you only need some distance for velocity magnitude

[quick pollen]

yeayea

I mean

i feel stupid for making all those calculations

and now it being useless

[shut swallow]

lmfao

I mean i wrote this down earlier lol

[shut swallow]

more than an hour ago

[quick pollen]

One can also ask what launch angle allows the lowest possible launch velocity. This occurs when the two solutions above are equal, implying that the quantity under the square root sign is zero. This, tan θ = v2/gx, requires solving a quadratic equation for

wait this isnt it

I would want to make it so the angle is based on a velocity maybe?

problem with that is itd be the opposite of what i want

itd take longer the closer you were

instead of longer the further you were

[naive pawn]

you're overcomplicating it

[shut swallow]

ight its like 1am in aus imma tap out first, but you can always set velocity for angle and angle for velocity if you use this equation

[naive pawn]

just set a constant angle

so the horizontal speed and velocity stay relatively consistent

as in, v_x = kv

k being cos(a)

[quick pollen]

If I make the angle be a constant, then I need to calculate the minimum velocity required to hit the player

[naive pawn]

no it's just. 1 exact value

[shut swallow]

which is given by my equation

it's 1 value

[naive pawn]

v = sqrt(-2sg/sqrt3)

(assuming gravity is negative)

[quick pollen]

what is u here?

[shut swallow]

x is distance, u is inital velocity and theta is angle in radians

[naive pawn]

initial velocity

[quick pollen]

yes, and I need to solve for u

gimme a sec

i can do this maths myself i think

what's a tho?

[naive pawn]

here's for theta=60°

[naive pawn]

acceleration, gravity in this case

[shut swallow]

a is acceration which is gravity

[quick pollen]

ahh

okok

fuck its rotated

whatever

[shut swallow]

yea looks right enough

[quick pollen]

does it matter if its in rads or degs?

it shouldnt, right?

[shut swallow]

yes

it does

[quick pollen]

I need to convert it later anyway

[naive pawn]

it does for the function you use in code

[shut swallow]

it's in rads

[quick pollen]

yea thats what I mean

[naive pawn]

degrees is just a constant, π/180

[quick pollen]

I can just convert the output of the sine to degrees

[naive pawn]

uh.. no?

[shut swallow]

oh yea nvm double angle works on deg too

lmfao

[shut swallow]

?????
you can just...plug the values straight in no?

v is in a number

not some angle

[quick pollen]

oh

yea

so wait

Mathf.Sqrt(d*g/(float)Math.Sin(2*angle))

this is it, no?

angle is a deg tho

not a rad

but it shouldnt matter

[naive pawn]

then convert it lol

[naive pawn]

it does here

when you actually. yknow. give it to something else

[quick pollen]

why do I need to convert the angle to rad?

[naive pawn]

because Sin expects rad

[quick pollen]

then I have to convert the sin to deg too?

[naive pawn]

what?

sin doesn't output an angle

[quick pollen]

oh wait

fuck this is sin not asin

[shut swallow]

sin takes a rad input and spits out a value

lmfao

[quick pollen]

im stupid

[naive pawn]

aren't we all

[shut swallow]

fair enough

[quick pollen]

often it feels like no lmao

[shut swallow]

a bracket killed my code

and I spent like 30 minutes to find where i fucked up

love it

[quick pollen]

i did smth similar like that too an hour ago

[shut swallow]

peak

[quick pollen]

i was so confused

ehm

float v = Mathf.Sqrt(d * g / (float)Math.Sin(2 * Mathf.Deg2Rad * (angle + 180)));

pemdas issue maybe?

nope

idk what it is wait

[naive pawn]

what are you assigning on the line given in the stacktrace?

[shut swallow]

why is v a float

[quick pollen]

I mean

rb.velocity.normalized * v

[naive pawn]

why shouldn't it

[naive pawn]

why you doing angle + 180

[quick pollen]

it worked before for d

[quick pollen]

for some reason its rotated wrong

its looking into the ground

[shut swallow]

mb i should rephrase, why is input velocity nan

[quick pollen]

and I'd rather work in degrees

[naive pawn]

what's g?

[shut swallow]

usually that happens when you plug a float in

[quick pollen]

idk, thats the issue

[naive pawn]

how did you define g in

[quick pollen]

float g = Physics.gravity.y;

oh

[naive pawn]

that'll be negative

[quick pollen]

fuck

right

[naive pawn]

that's why it was the wrong direction

[shut swallow]

can you just

[naive pawn]

it needs to be flipped, not rotated 180

[shut swallow]

g = 9.8

[quick pollen]

and thats why it was nan

because the sqrt had a negative value in it

[shut swallow]

angle + 180 is in quadrant 3 or 4

answer is a negative

it's not about the square root

[quick pollen]

that wasnt the main issue

it was about the sqrt

distance is positive

I made it -Physics.gravity.y and it no longer does that shit

[shut swallow]

think of this: negative divide by negative is positive

top and bottom are negative

[quick pollen]

i fixed it

        d = Vector3.Distance(transform.position, targetPosition);
        float v = Mathf.Sqrt(d * g / (float)Math.Sin(2 * Mathf.Deg2Rad * angle));
        float playerAngle = Quaternion.LookRotation(targetPosition - transform.position).eulerAngles.y;
        transform.rotation = Quaternion.Euler(angle + 180, playerAngle + 180, 0f);```

not exactly intuitive

but if i dont do this i get a negative sqrt

[shut swallow]

Yep the v is now correctly written

[quick pollen]

thank you @shut swallow and @naive pawn for the help!
guess i learned quite a bit of physics

[naive pawn]

use Mathf instead of Math

(on the Sin call)

that's why you're getting a double instead of a float

[quick pollen]

oh

good to know :)

[quick pollen]

where did you pull this formula out of tho?

[shut swallow]

Here

[quick pollen]

and those formulas?

[naive pawn]

those are pretty basic kinematics

[shut swallow]

Yea

[quick pollen]

my physics teacher is an ass

i need to learn all this by myself

and im not saying this as like a rebel

[shut swallow]

In projectile motion at the top of the parabola, velocity in the y direction is 0 and half of total time has passed

[quick pollen]

he straight up threatens you if you ask a question

[shut swallow]

🤨

[naive pawn]

i thought you said teacher

[quick pollen]

yes?

[shut swallow]

Ight it's 2am here

[naive pawn]

that aint a teacher

[quick pollen]

what is it then

[naive pawn]

an asshole with a degree

[quick pollen]

have a good night!

[quick pollen]

yep, I guess I should say employee at my school

fr tho

I had to get into quantum mechanics without him

I just started doing gamedev and such on his classes

and he gets mad that im not looking at the presentation hes reading

others are just playing videogames or sleeping

at least i do smth productive

and somewhat physics related

I like physics a lot, and I am trying to learn it, mainly through gamedev rn, I just hate him, and it discourages me from even trying when he gets mad that I don't know the formulas stuff like, idk number of oscillations over x time
(rant over, sorry for off topic)

[noble cedar]

can someone tell me what is bigginer code like
would linking JSON to Database looking the data and uploading to each other whatever has higher value
would count as begginer code or should I go to advance or general?

[naive pawn]

that would probably go in #archived-code-general

[noble cedar]

nvm I found the mistake I was dumb I switched Key value with IV value

[naive pawn]

@quick pollen anyways here's a (relatively) brief explanation coming from the basics

• a velocity 𝑣 with an angle 𝛼 to the plane can be split into 2 components, 𝑣ₓ = 𝑣cos𝛼, 𝑣ᵧ = 𝑣sin𝛼
• the time it takes to travel back to the same plane: v = u + at (final velocity = initial velocity + acceleration * time)
  • when it comes back down it'll be the same speed, but in the opposite direction
  • -𝑣ᵧ = 𝑣ᵧ + 𝑔𝑡 ⇒ 𝑡 = -2𝑣ᵧ / 𝑔
• the time it takes to travel some distance - s = vt (displacement = velocity * time)
  • 𝑠 = 𝑣ₓ𝑡
• ⇒ 𝑠 = 𝑣ₓ * -2𝑣ᵧ / 𝑔
• ⇒ -½ 𝑠𝑔 = 𝑣ₓ𝑣ᵧ
• ⇒ -½ 𝑠𝑔 = 𝑣²sin𝛼cos𝛼
• sinAcosA = ½ sin2A
• ⇒ -½ 𝑠𝑔 = 𝑣² ½ sin2𝛼
• ⇒ 𝑣 = √(-𝑠𝑔/sin2𝛼)

i probably didn't have to do the full working, huh...
idk, just a habit lol

[quick pollen]

ahhh

tysm for the explanation!

i think i get it

(ngl i usually use integrals to calculate displacement, but if the velocity is linear then it doesnt matter ig)

also ngl i didnt know you can split a velocity vector into 2 components like that

[willow raptor]

I am insanely new literally just started like 20 mins ago what did i do wrong trying to do some movement stuff

watching a tutorial

[naive pawn]

you didn't open the method

[willow raptor]

huh

[naive pawn]

look at the tutorial code closer, you haven't followed it accurately

[polar acorn]

{ } you dropped these

[willow raptor]

yeah io was looking for those they didnt come up

[polar acorn]

What do you mean "they didn't come up"?

They come up when you type them

[willow raptor]

last time they came up automatically

[polar acorn]

It'll make an end brace when you type the start brace

[naive pawn]

and.. what's the issue with typing them yourself

[willow raptor]

there is no issue i was just wondering if i did something wrong

[naive pawn]

you didn't add { }, that's what you did wrong lol

[willow raptor]

i know

can i just paste them in

[naive pawn]

...why

[solid heart]

yea

[naive pawn]

just type them lol

[willow raptor]

bro i dont have them on my keyboard

[solid heart]

yea you can copy and past them

[naive pawn]

what keyboard are you using

braces are used very often

[willow raptor]

not sure its a 60% keyboard

[polar acorn]

[naive pawn]

relying on copy/paste will be a pain

[naive pawn]

what layout do you have

this isn't a control key

it's not removed by being 60%

[willow raptor]

idk where they are but ill just paste them for now

[naive pawn]

is it qwerty?

[polar acorn]

Just like... look at your keyboard

and find the buttons

[naive pawn]

{ is shift+[, } is shift+]

[polar acorn]

You're not going to be pasting braces for the entirety of your time programming

[willow raptor]

im doing it for now

[polar acorn]

Is your neck broken

can you not look down

[naive pawn]

braces are used very frequently

just find them

why do you want to make life harder for yourself

[night mural]

maybe python is more your speed?

[willow raptor]

im going to paste them once

[naive pawn]

python uses braces too

for dicts and sets

[willow raptor]

and then ill man up and find it

[polar acorn]

In the time you've spent arguing why you can't look down, you could have just looked down

[naive pawn]

my brother in christ, look down

[willow raptor]

that is true

2 sec

[night mural]

looking down intensifies

[willow raptor]

i found them but i dont know what combination

[night mural]

try doing like 2 hyphens and a bar |

and then rearrange them and squish them

[naive pawn]

...you don't know how the shift key works?

[night mural]

hey they said they found them already

[willow raptor]

.............. on my keyboard.... there is æ and ø

[keen cargo]

to be completely fair to them, it entirely depends on the keyboard language

[naive pawn]

that's why i asked what layout you're using

you didn't answer

so i assumed lol

[willow raptor]

im not a nerd so i dk

just joking

[naive pawn]

this isn't a nerd thing

what language is the keyboard for?

[willow raptor]

norwegian

[keen cargo]

try R-ALT + 7 for {, R-ALT + 0 for }

that's what works on my Finnish keyboard

[ivory bobcat]

It's been asked because folks were willing to go out of their way to address the location of it relative to keyboard layout.

[night mural]

sometimes you're too busy being the semunGOAT

[naive pawn]

this one?

[keen cargo]

yep thats the one

mine looks exaclty like it

[willow raptor]

are u norwegian

[keen cargo]

no, finnish

[naive pawn]

the symbols on the right of each key are for altgr
so it's altgr + 7 for { and altgr + 0 for }

[willow raptor]

ooh

omg

i did it

fouind it

[keen cargo]

well ok i'm not "finnish", i live in finland

but yes you need to know how to enter your own braces

[willow raptor]

chris your a savior

a legend

[naive pawn]

i mean.. did you not know how to use altgr before?

[night mural]

to be fair, skemp gave you the answer earlier

[naive pawn]

ah yeah didn't notice 🐌

[night mural]

altgr? what are we, dogs?

[naive pawn]

alternative graphic

[keen cargo]

alt grrr

[night mural]

alt meow

[willow raptor]

im not a nerd

[naive pawn]

this isn't a nerd thing

this is how to use a keyboard

[night mural]

you are on discord asking for help programming

sounds like a nerd to me

[keen cargo]

how to use keyboard tutorial, 2025, free, no virus

[naive pawn]

such a low bar 😆

[rocky canyon]

lol.. everyone here is a nerd

maybe not a geek

[willow raptor]

my goal is to become a nerd thanks to chris for bringing me 1 step closer

[polar acorn]

Fellas is it nerdy to know what country you're in

[naive pawn]

we're on discord because we have social ineptitude
we're all geeks

[rocky canyon]

my IRL friends dont know i have a discord 😉

[keen cargo]

your next step is to go through the C# tutorial from Microsoft first

[rocky canyon]

thats a good step 👍

[keen cargo]

https://learn.microsoft.com/en-us/dotnet/csharp/tour-of-csharp/tutorials/

since you had issues with the code not working without braces {}

[naive pawn]

what's a friend

[keen cargo]

you should know the basics from here

[willow raptor]

ill try it later thanks boss

[keen cargo]

go through that, and then !learn

can i use a script macine and a state machine a t the same time when i do code a 2d game with visual scripting?

[slender nymph]

wdym by a "script macine"? also if you have visual scripting questions they belong in the #763499475641172029 server

[ripe galleon]

script machine

thanks, i will join it and ask there

[slender nymph]

and "script machine" means what in this context?

[polar acorn]

I think that was the nickname hollywood producers gave to Stephen King in the 80s

[ripe galleon]

you have a code in the script machine, but i did see that the state machine also does use codes(nodes) in the tutorial

[keen cargo]

do you mean the IDE??

[polar acorn]

It looks like "Script Machine" is a visual scripting component. No one here is really going to know what that is

We use code here

[ripe galleon]

ok, i just wanted to answer to the question boxfriend asked

[keen cargo]

oh yeah just looked it up, it's all visual scripting stuff

[slender nymph]

and you managed to not actually answer it. digi's response was actually informative though. but yes, this is definitely not the place to get help with visual scripting because we are sane people here

[keen cargo]

i remember my first project's teacher said to use visual scripting for a state machine lol...

i did not end up doing that

[ripe galleon]

ah...i am just confused because there would be 2 parts where codes are

[slender nymph]

that actually makes some amount of sense though, provided you actually implement the states themselves in code and just expose them as nodes. which is pretty much what the animator controller is

[keen cargo]

true, i just remember he was being really vague about it, i looked up visual scripting and got turned off immediately lol

[rocky canyon]

yup, like the average person

[torn verge]

I don't know if this is the right place to write this but I'll post it anyway. I have a problem with battle scenes conflicting with my overworld scenes. My "game" is a game with multiple rooms/scenes and I use DDOL on my player to retain my player position when switching scenes. Basically I make a door that change scene then I make position the scene where the door is, so when I switch back scene I spawn at the door. But I wanna make a battle-arena scene that appears when encountering an enemy. And I want my player to be in the same position that it was before the battle after the battle is over. Could I possibly store the player position then teleport to it after the battle is over? How would I do this?

BTW I want my player to be in the battle-arena scene since Im going to be able walk around and dodge the enemy's attack in this case the "Flame enemy" lol

[rocky canyon]

Could I possibly store the player position then teleport to it after the battle is over? How would I do this?
not sure y u couldn't? something like a gamemanager keeping track of where the player will spawn bakc into.. jus like the DDOl stuff

[torn verge]

Is there a better way to this?

[rocky canyon]

it'd have to be something persistent

ur player gets spawned in correct? couldnt be on the player.. u said u have some DOOL stuff.. could possibly cache it and use it there

[torn verge]

My player is in the DDOL stuff

[rocky canyon]

well if ur player sticks around.. and ur not instantiating it in..
u could probably put a variable on it and change it as needed

then when u need to reposition him or w/e u just read from its variable

next time u go thru door or into battle.. just give the player his "returning position"

[gentle charm]

im trying to do multiplayer, i've pretty much done it all its just getting it so when the 2nd player spawns it doesnt take over the camera

[torn verge]

alr workin on it

[lapis sentinel]

hye im a beginner in unity and utilize this software in my daily work. Im trying to be prepared if given task related to unity. I have been discovering the unity for 1 month.

The issue i had with unity is when writing c# script. How to find the directory name and its related class because some directory or should i say Meta sometimes does not have an up to date documentation about the directory i want to use . Soo how does the big shot and pro league manage to get their hands to utilize this scrambled documentation and directory.

sometime the class name i use does not recognize the directory im ising although it stated in the doccumentation

[slender nymph]

what do you mean by "the directory" in this?

[gentle charm]

how do i fix this

[slender nymph]

#archived-networking

[gentle charm]

oh, i just figured since it was on the same machine it didnt need any wouldn't be networking related

[grand snow]

Well i presume in this "battle scene" you dont need the same player components right? Why not have the player sprite/model in this battle scene to start

[slender nymph]

you're literally using a networking library

[gentle charm]

true

[slender nymph]

if you are trying to do local multiplayer then you don't need a networking library so you're doing it wrong anyway

[torn verge]

Should I hide the player during battle, It's still going to be in the battle scene since its under DDOL

[grand snow]

Are you talking about namespaces? you need to give more information cus what you just said hardly makes sense...

Then thats a flaw and you should not use DDOL OR hide it during this
