[muted sapphire]

the only language ive seen doing that is python

[stuck field]

This is right, but it bugs people

[muted sapphire]

I'd have manually put it down the exact same way the code did

[stuck field]

Usually it should do 4 spaces (which is one tab)

Looks to be doing 3 up there

[onyx geyser]

update, i got to work after a bit of searching

[muted sapphire]

ohh thats what you mean

that seems like a configuration issue

[stuck field]

Yeah, it's likely

[onyx geyser]

so it turns, i just needed to do a normalized.
rb.Velocity = rb.Velocity.normalized

sorta way

if i understand it right, by saying normalized, it's taking the original vector's "speed" and constantly reverting the speed of the new Vector2 back to that specific speed

if anyone can clue me in on if that interpretation is correct

[stuck field]

Normalization scales the vector to a magnitude of 1

[muted sapphire]

I have no idea how that fancy stuff works

[stuck field]

I don't think it'd be the right thing to use

(Also reduces it to 1 if above)

[muted sapphire]

I feel like youve got bigger fish to fry

[onyx geyser]

well it certaintly worked on stopping the ball from growing in speed, and it's such a short line, why would it be the wrong thing to use

[muted sapphire]

shouldnt you try to fix the issue of it getting faster

instead of countering it

[onyx geyser]

well i tried finding the issue online, and, didn't really understand anything, i figured this is constantly reverting the speed back to what flyspeed is meant to be, as i can change flyspeed and it affects the zubat- i mean ball.

[muted sapphire]

It works

but it's not pretty

[onyx geyser]

oh?

if(rb.velocity.magnitude > Flyspeed)
{
rb.velocity = rb.velocity.normalized * Flyspeed;
}

wym

[stuck field]

Why not just clamp the velocity?

[onyx geyser]

idk how clamp works

i can give it a try

what's the difference between normalized magnitude and clamp?

[stuck field]

It takes a min and a max value and makes sure the inputted value isn't below min, or above max

Normalized sets the magnitude to 1

Clamp makes a value go between a specified min and max value

It's more pretty and less code than what you're currently doing at the very least

[onyx geyser]

really?

less code that 5 lines?

[stuck field]

Yeah, you won't need an if statement

It's just to set a max value, let's say your max was Flyspeed, you would clamp the velocity to a min of 0 (or -flyspeed), and max of flyspeed

That way velocity will always be at min what you specify, and max what you specify

https://docs.unity3d.com/ScriptReference/Mathf.Clamp.html

You can see how it works here

[onyx geyser]

no overload for method clamp

[stuck field]

Mathf.Clamp, it's not Vector.Clamp

[onyx geyser]

yeah, i'm using mathf.Clamp

[stuck field]

Can you show me?

[onyx geyser]

rb.velocity = Mathf.Clamp(-Flyspeed, Flyspeed);

[stuck field]

You need to put the actual value you're trying to clamp in

(val, min, max)

[onyx geyser]

oh ?

[stuck field]

It's a little messy as you'll need to use the individual floats actually, but it can be one line

It'll work better though

[onyx geyser]

individual floats?

[stuck field]

Vector3.x

Y and z too

[onyx geyser]

ohh

like xvelocity and yvelocity

[stuck field]

Yeah

Pretty much creating a new vector3 with the clamped values

[onyx geyser]

so would be.. like mathf.clamp(vector2) kinda deal

i'm a little confused, never used clamp before

[stuck field]

The documentation will show you how to use it better if you want to go check it out quickly

[stuck field]

I've linked it here

[eternal needle]

There is indeed a way to do this through vector3 though
https://docs.unity3d.com/ScriptReference/Vector3.ClampMagnitude.html

[stuck field]

I'm not too sure that's what is being looked for

It works on the positive end, but not the negative

[eternal needle]

Or vector2 if thats what they're looking for. Didn't see the full context above

[stuck field]

It's Vector3 I believe, but they are trying to clamp between -speed and speed, clamp magnitude would only allow speed, not both I believe

Correct me if I'm wrong though

[onyx geyser]

Vector2, i'm trying to stop a ball from gaining too much speed

[eternal needle]

I dont know what they're fully doing since this seems to be a long conversation. This is what I'm going off of

[onyx geyser]

seems the tutorial i used wasn't very decent

[eternal needle]

Magnitude is a positive value. Look at the equation for length of a line

[stuck field]

I'm aware

Kind of makes sense

I just was thinking magnitude didn't work that way, so my apologies

But yeah, then that should work too

[onyx geyser]

so if i make a few more floats for maximum and minimum, it'll make the clamp usable?

[stuck field]

You should use what bawsi said, more compact and cleaner

[eternal needle]

Look at the docs for Vector2 or Vector3.ClampMagnitude. I linked the vector3 doc above. They show you exactly how to use it

[onyx geyser]

well it's come up, so i'm curious as to how i would apply this to my code

[stuck field]

If you want to know more about clamp, I would recommend the docs, it just takes 3 floating point values, the first being the value you want to clamp, the second being the min value the clamped value can get to, and the third being the max value the clamped value can get to

But I highly recommend using ClampMagnitude for this now that it's been brought up, it's a better solution

[onyx geyser]

oh wow, i read through it a little bit

it worked

huh

[eternal needle]

This code you had could be replaced with ClampMagnitude. That is all

[onyx geyser]

one line, easier to understand

i'm still pretty proud of that if statement, but i'm glad you showed me this

so if i have it right.
rb.velocity = vector2.ClampMagnitude(rb.velocity, Flyspeed);
it's saying that rb.Velocity, aka the ball is being clamped directly by what it's set to? which would be Flyspeed?

did i get that right?

[stuck field]

Yup, it would clamp the magnitude of the vector to fly speed

[sour fulcrum]

Unity and C# has a wonderful range of utility functions that are likely doing pretty simple conditional checks behind the scenes 😄. Behind every clean piece of code is probably a re-usable check like yours

[onyx geyser]

that's true, and the more i screw around even with something as simple as this, the more i'm starting to get it

a few days ago i didn't get any of what i typed

i still don't get a few things but i understand this now

how difficult would it be to set the corners of my paddles to send the ball down by .5 degrees?

i'd probably need a seperate box for them right?

[stuck field]

Not sure what you mean

[muted sapphire]

I literally started the editor with two cubes and one script in it and got SEVEN errors to my face

[onyx geyser]

well, in pong, when the ball hit's a corner, it sends it off in the direction of whichever corner it's on, but it might be easier to make it so the ball randomizes which direction it slings to upon making contact

[eternal needle]

You dont need separate colliders, it could work but id avoid it. You'd also have to solve the issue of a ball hitting multiple colliders.
You could do this with math simply by checking how far up or down the ball is compared to the center of your object

[onyx geyser]

oh ?

that sounds a bit more complex on it's own

might be worth a try

[eternal needle]

Its a very basic formula at most

[muted sapphire]

oh my god theres an unity debugger for visual studio code

I've been freestyling my code

[eternal needle]

Do also consider that these old games weren't using unity and advanced physics engines.
This should definitely be done with basic math. I assume you want the angle to vary depending on how high up or down it hit

A math formula solves this right away

[onyx geyser]

Eh, roughly, I just don't want it to stay directly in the middle

[muted sapphire]

or there isn't because it errors while installing and I'm far too lazy to bug with that now

[onyx geyser]

It'd be nice to be able to have 3 points, a bottom, middle, and top.
If it hits the bottom, it goes down, if middle, it goes straight, if top, goes top

Side note, I've been using pokemon sprites and they've been knocking around a zubat

[muted sapphire]

for now I'd just give the ball like 0.5x the velocity of the paddle or something

when hitting it

meaning when moving up it gets speed upward

when down it gets it downward

it's what i wouldve settled on without mathing it through

[onyx geyser]

well that's no fun, maybe it's worth a try making seperate points of contact

[eternal needle]

Maybe look into how it works in the actual pong game. I'm fairly certain that the angle directly corresponds to the height it hit on the paddle but I could be wrong. Anyways truthfully it's a lot easier here to use a basic formula, giving you this result anyways. Rather than 3 points of contact, each contact sending the ball in the same angle everytime

Multiple colliders for something as simple as a pong paddle is questionable. If youre using this as a learning project, consider learning the simple math here

[onyx geyser]

that might be a good idea

[muted sapphire]

How do i get a single value from a vector?

(Vector2, in this case)

[naive pawn]

@muted sapphire sounds like you're thinking of wasd as 4 separate buttons? but you haven't set up your inputs like that
the composite control means wasd are being treated as separate sides of a single joystick, so there's no relevant bool to speak of

[onyx geyser]

i'm thinking what i could do is make an if statement that goes something like
if(collision=true)
{
randomize ball direction
}

but then it may also be a good idea to do the math, i just have no clue how i'd approach that topic

[naive pawn]

a single dimension? that'd be .x or .y

[muted sapphire]

thanks

im just restructuring my movement system right now trying to figure it out

[eternal needle]

The collision itself can be through unitys physics messages like OnCollisionEnter2D. The math i was telling you to do was purely for the angle when the ball reflects

[onyx geyser]

i figured as much, just didn't know.
i can probably go back to my flappy bird script and take a better look at how it reacts to collision and make a choice from there

[muted sapphire]

okay, so in simple words, how will i do something once one of these actions happen?

or should i be using axes for this

[eternal needle]

Have you looked at any tutorials for the new input system? There are a couple different ways to get notified of input in a script, or read the values directly

[muted sapphire]

The official Unity tutorials are so sunshine and rainbows im not finding anything

And so far I'm working off of a (i think) 6 year old handbook

[eternal needle]

I mentioned where some resources are up here

[muted sapphire]

Yeah the main input system guide is structured so weirdly though

I have to search for the most simple things because they're buried somewhere

Alright got it to work although not beautifully

[eternal needle]

The first resource pinned in there should be plenty. Maybe slow down and just read through the docs. The 2nd page of the introduction (quickstart guide) lists a way to read input. There are a few ways like the player input component too https://docs.unity3d.com/Packages/com.unity.inputsystem@1.14/manual/PlayerInput.html

[muted sapphire]

What I meant was

The first proper explanatory tab in the resource starts with working out moving with two dimensional axes

THEN the first single press action is called

[onyx geyser]

trying to wrap my brain around how i'd just go about changing the angle upon hitting a collision

[muted sapphire]

...how did i even do this

[onyx geyser]

i don't think i'm deep enough in to do math right now, BUT, i can do something else

[lusty star]

yessss but uh, there is an option for that in the settings right?

i mean i didnt even check lol lemme check

yeah cant find it

[onyx geyser]

well, turning the box collider into capsul colliders seemed to work pretty damn good

[stuck field]

I have no idea, never had the issue, I would say try searching it up if not already

[onyx geyser]

but i run into another issue, some time after, it just gets stuck between both walls, bouncing continously

which, to be honest, might solve the problem i had with the box colliders

[lusty star]

yeah i kinda dont know how to search it up??? i search "vscode no correct amount of space when autocompleting" and it doesnt work

[stuck field]

Maybe this can help? https://stackoverflow.com/questions/49167053/how-do-i-change-vscode-to-indent-4-spaces-instead-of-default-2

[naive pawn]

it does, it just has different restrictions
python doesn't require semis, c# does
c# doesn't care about whitespace, python does

make sure you've configured c# to 4 spaces i suppose

[stuck field]

Here too, has the same kind of answer: https://code.visualstudio.com/docs/editing/codebasics

[muted sapphire]

Really? Can i no longer oneliner my code? thats sad

I loved breaking coding conventions just to confuse someone that saw my code

[naive pawn]

the spacing in question is called indenting, so that might gice better results

[stuck field]

You confuse yourself too 😭

[naive pawn]

where did i say that..?

[muted sapphire]

Maybe my original statement was weirdly formatted

but the only language i know that watches graphical syntax is python

[naive pawn]

you can do one liners in most languages, except a few features like if/else in python, nested control in python, preprocessor statements in c/c++

[naive pawn]

syntax is purely graphical

[muted sapphire]

depends on definition

[naive pawn]

you're thinking of whitespace significance

[muted sapphire]

one could argue syntax is things like ; or ()

which isnt graphical

[naive pawn]

everything you see on the screen is graphical. that's what graphical means

[muted sapphire]

no??? its data

bytes

[naive pawn]

those are syntax elements, sure

[muted sapphire]

yeah

[naive pawn]

you're not seeing the raw data, you're seeing graphics

[muted sapphire]

mostly yeah

[naive pawn]

im not sure what point you're trying to make here

[muted sapphire]

sigh

[naive pawn]

there are quite specific terms for these

"depends on definition" doesn't really work when the thing you're talking about has a single accepted definition

[muted sapphire]

usually in our circles we call both ();<> and so onward and whitespaces syntax

one because it is language syntax

the other is grammatical syntax so it goes better on our eyes

which is also language syntax in python

Thanks to python this established

It's really not so off one should have trouble understanding

[onyx geyser]

i have learned of reflect, i feel like this might be usable for this scenario

as the ball tends to get stuck between the two walls

[naive pawn]

what defines "language syntax" vs "grammatical syntax" to you
never heard of this distinction before

[muted sapphire]

take c

you have things like semicolons

or brackets

thats NECESSARY for the code to read what you write

[lusty star]

yes i want thru the pages but everything seems fine? the spaces are 4

[muted sapphire]

you NEED to do that

[lusty star]

ohhhhh thank you :)

[muted sapphire]

but theres other options, usually conventions, which is what you called whitespace significance and a couple tiny other things

in python thats significant too

[naive pawn]

indenting is styling/formatting, not syntax in c

syntax is specifically the things that matter to the language

[muted sapphire]

This

[muted sapphire]

And thsi

[naive pawn]

i have no idea what you're trying to say in those messages other than "whitespace is a part of syntax"

[muted sapphire]

Come on, I see your point but it REALLY isn't that hard to understand???

I'm not saying whitespace is a part of syntax

[naive pawn]

hell, c uses whitespace in its syntax, preprocessor statements have to end on a newline

[muted sapphire]

I asked if c used whitespace, which i referred to as syntax, meaning graphical syntax which is what we call whitespacing

[naive pawn]

maybe, but i don't understand what you're trying to convey, rather than your actual stance

i don't know what your stance is

[stuck field]

Can you see the Tab Size on the status bar?

Looks like this

[naive pawn]

so you call formatting as "graphical syntax"?

[muted sapphire]

yes

again, coming from python

[naive pawn]

they're still separate things in python

[muted sapphire]

not relaly

you get syntax errors for formatting something wrong

[naive pawn]

i know how python works lol

[muted sapphire]

I'm not explaining to you how python works

im telling you that if there is an error in the formatting and that error is a syntax error, then the formatting is a part of the syntax

[naive pawn]

formatting and syntax overlap here but they're not the same
formatting also defines how much to indent by, and makes it consistent, etc
the syntax says you can also just not have a newline and indent at all

[muted sapphire]

theres still a bit of whitespacing in python, but formatting is now a part of the synta

[naive pawn]

they occupy the same space, sure, but they are not one and the same

[muted sapphire]

its just like it always is, you have free space to choose how much whitespace you want to have

i think this is an opinional debate, theres not really right or wrong here

lets just agree to disagree

[naive pawn]

whitespace is involved in syntax
whitespace is involved in formatting
formatting isn't involved in syntax

[naive pawn]

these are terms that are quite agreed upon though lol

but sure, you're free to ignore the established terms if you so choose

[muted sapphire]

it is also quite agreed upon pythons syntax contains formatting

[lusty star]

yeah but it shows as spaces

[muted sapphire]

you cant argue with whats quite established because so is this
most people ive met would disagree with you
conventions are relative compared to the people you convene with

[stuck field]

What do you mean?

[onyx geyser]

would anyone happen to know how to change the angle at which a ball bounces off a collider, so that when it's bouncing between walls it doesn't normalize between them and get stuck?

tried using reflect, that didn't work, since it just reflects the way it came

[naive pawn]

you got a source on this?

[muted sapphire]

it is quite agreed upon

it is a convention

one can find a source to any convention if they so like

[sour fulcrum]

you can't change the angle a ball bounces off a collider, since that's natural physics

you can make things go in specific directions
and
you can know when a collision happens

if you are already trying to do both of these things (maybe via reflect) you can post your attempted code and we can help more

[muted sapphire]

its all a question of the people you convene with, like i said

[lusty star]

you can see it in the vid

[naive pawn]

formatting is about the non-functional parts
syntax is about the functional parts
mixing them just causes issues with communication and managing tooling lol
ive never heard an actual take mixing formatting and syntax lol

[lusty star]

like exectly what you showed but instead of tab it says space

[onyx geyser]

private void OnCollisionEnter2D(Collision2D collision)
{
Vector2 inDirection = rb.velocity;
Vector2 inNormal = collision.contacts[0].normal;
Vector2 newVelocity = Vector2.Reflect(inDirection, inNormal);
}
i found something somewhere and decided to see if it worked, if it did, i was going to look into why it worked

doesn't work, maybe because i'm doing something wrong

[sour fulcrum]

Vector2 newVelocity is a value, you'd have to actually use that value

[naive pawn]

i didn't find any though lmao

[muted sapphire]

maybe the people and forums you surround yourself with say formatting and syntax are not related to one another because formatting is purely for the human to read
the people and forums I surround myself with say that formatting is all whitespace (so newlines, tabs, spaces, et cetera), which is usually only for the human to read, but python needs it, which is why that bleeds over

[muted sapphire]

well thats too bad

I'm not pulling this out of thin air, this has been deep core anchored with most people I've met in forums or on discords

[sour fulcrum]

(not saying your wrong or right but heads up that this comment has some weird tonal energy homie)

[naive pawn]

#💻┃code-beginner message

[muted sapphire]

code beginner unity

not code beginner c

[naive pawn]

i feel like that's just a misunderstanding on your part

[muted sapphire]

no

i literally just said it

[sour fulcrum]

(Unity uses c#)

[muted sapphire]

most people i meet consider whitespacing and formatting one and the same thing

[naive pawn]

well that's just not right

formatting involves so much more

[sour fulcrum]

Maybe i'm ignorant but isn't all whitespacing formatting but not all formatting is whitespacing?

[muted sapphire]

...yeah? Unity still has its oddities

which would still make formatting partially a part of syntax

[sour fulcrum]

in python i guess, not c#?

[naive pawn]

quotes type in languages where it's flexible
declaration type/style
implicit modifiers
inline/oneline statements
array style

[onyx geyser]

so am i to assume this IS a step in the right direction?

[stuck field]

I'm not sure then, the only other thing I can think of is the "detectIndentation" setting that may be getting 2 and not showing the spaces value, if not I'm not really sure and I recommend going directly to vscode support on this as that shouldn't really be happening if all settings are right, otherwise, you can try reinstalling vscode or installing visual studio instead and maybe that will work properly

[naive pawn]

we were talking about python - i was pointing out whitespace does double duty as formatting and syntax, not the formatting is syntax

[muted sapphire]

formatting is syntax is not true to what ive said

[naive pawn]

unity doesn't create new syntax though

[muted sapphire]

a part of formatting is a part of syntax

[naive pawn]

"formatting is not part of syntax", then

[muted sapphire]

a part of formatting is a part of syntax though, which makes formatting involved in syntax

they are not seperate

[sour fulcrum]

In the right direction yeah, any aspect of that code specifically that confuses you? (i'd guess normal might be a new term?)

[sour fulcrum]

imo syntax is part of formatting, formatting is not part of syntax

[naive pawn]

ooh new take

[onyx geyser]

so when i'm using vector 2 in this case, am i referring to the direction the ball is headed?

[muted sapphire]

im here to learn about how to make my code interact with my Unity project

[naive pawn]

this seems like a weird take to me, are formatting and style not synonymous to you

[onyx geyser]

and when using inDirection = rb.velocity, i'm assuming that's where the ball came from?

so in order to 'change direction', i'd have to change something inNormal, but i have no idea how to go about changing that

all of in.normals code piece confuses me

[sour fulcrum]

in my brain rn

syntax: ""identifiers"" on how to correctly read the language
conventions: trending ways on composing aspects of the language
formatting: the usage of syntax and conventions to write the language

not saying this is right whatsoever just how my brain is doing it

[muted sapphire]

let me make my stance more clear

with this terrible venn diagram

[naive pawn]

yeah syntax generally covers a lot more than the tokens, specifically how you can legally link the tokens together

[sour fulcrum]

in what language is this made for

[muted sapphire]

python

[naive pawn]

that's in the realm of syntax, not formatting

[sour fulcrum]

i disagree then, since whitespace composition is required syntax. you would format your code around this requirement

[naive pawn]

hmm wait my stance would be the same but i'd probably define what the overlap means differently LMAO

[muted sapphire]

I made that venn diagram in like two seconds okay

cut me some slack

[lusty star]

alright i understood thank you very much :)

[naive pawn]

my take is you need some whitespace according to syntax, but formatting defines how much to put in

[onyx geyser]

to kinda bring light back to this for a moment, if i'm correct in my theory, the part that confuses me (second line, inNormal) is the same line i would use to tell the ball to go 5 degrees out of it's normal pathing

(idk if it was obvious, i'm trying hard not to ask for a direct answer, but this seems like one of those more obscure things)

[sour fulcrum]

so couple things

inDirection :the velocity of your rigidbody, easy
collision.contacts[0]: during a collision, there can be multiple "contact" points involved. eg if i slap you in the face there's gonna be one for my palm, fingers etc. this code just grabs the first one
.normal: every point on a collider has a normal value associated with it (as a Vector3). this normal is the direction this point is meant to face outwards. In this example if you hit a flat wall, said wall's normal is facing away from the wall (can you see why we would want this information)
Vector2.Reflect: as mentioned in the docs, takes in a incoming direction and a normal and will give you a reflected direction coming off that normal

[muted sapphire]

How do I make the Transform of my player object accessible to my cameras public Transform import?

[onyx geyser]

so i WAS mostly correct, that Normal is the line i need to be focusing on if i want to change the way the ball perceives it

[naive pawn]

what do you mean by "public Transform import"?

[burnt vapor]

By referencing it and accessing Transform.
https://unity.huh.how/references

[muted sapphire]

weird spelling in my question sorry

[sour fulcrum]

perhaps but based off that code alone none of it is doing anything because all you've done is calculate a value, you haven't used it anywhere

[onyx geyser]

yes i can absolutely see why we would need to know that information, because now the goal is to tell the ball that the normal it is hitting is not normal, while it's still remaining normal, as if it's hitting a corner

[muted sapphire]

i do a "public Transform player;" at the beginning of my camera script and then refer to this transform to define the new camera position

[burnt vapor]

It is a code smell to reference the player on the camera, though. if you need a reference on where to look at, add a TransformProvider or share the transform another way that doesn't put in a hard requirement

For example, you can also make it a delegate

[muted sapphire]

but in the selection in the menu on the side, the player objects Transform isn't visible, most likely because it is private

[onyx geyser]

so, how would i go about using this/changing it, i'm hitting some really new territory here

[burnt vapor]

Try .transform

[naive pawn]

in the..inspector?

[naive pawn]

ah no that's on the class you aren't supposed to assign stuff there

[muted sapphire]

I'll do the offset later lets leave that out of the thing

[naive pawn]

you need to assign stuff on an instance of the class, aka a component

[muted sapphire]

oh my god im blind

[sour fulcrum]

Gonna nitpick your thought process a little bit for learning if you don't mind

because now the goal is to tell the ball that the normal it is hitting is not normal
No, because the collision has happened. OnCollisionEnter is a reactionary function telling you what has happened, not a heads up on what is about to happen

What we want to do here (and what that code is doing) is use the information we have about the collision that did happen in order to tell the ball to move in a different direction. We don't need to change it's natural direction if we just tell it a new one

[muted sapphire]

i checked that before but the tabs for the variables were minimized, sorry

shouldve seen it

[naive pawn]

that's just inexperience, you'll get better with it over time

[onyx geyser]

oooh ok ok, i see.
so if i have it right.
were crashing the ball into the wall, upon contact, were telling it to change direction after it has hit.

[naive pawn]

nothing im not used to lol

[onyx geyser]

now that i get that, i still don't quite know how to use normal, i tried to make a float out of it and it told me the same thing you did, that it wasn't being used

[sour fulcrum]

you don't need to use the normal directly, you can use the result from reflect

[onyx geyser]

reflect is meant to use it i assume, judging by that last bit, but to change it is how I'm confused

[sour fulcrum]

well now we have the resulting value from reflect

and it's a vector3

[onyx geyser]

(or, vector2?)

[sour fulcrum]

and you've messed with a rigidbody's velocity before 😄

[onyx geyser]

of course

so now i have a new vector2 to use, which means i can do something like change it's direction to 5?

this stuff is confusing me beyond belief

[naive pawn]

not a Vector2 in 2d physics?

[sour fulcrum]

i goofed my b on that

[sour fulcrum]

thats fair, honestly this kind of stuff was super confusing to me at the start too

for starters i would break this down into steps and first try to use the reflect value you got with your rigidbody

see what it does 😄

[naive pawn]

ah ok, i was just confused since i don't fully understand how normals are represented lol

gotta check on that sometime...

[sour fulcrum]

just 0-1's

direction

[naive pawn]

think i got a good idea though actually since i saw something last night

it's not an arbitrary plane/line, is it? it's the one that passes through the origin and is perpendicular to the normal vector

and then projecting or reflecting with that plane or line involve directions, not positions - ie, relative to origin

[onyx geyser]

gonna mess around for a moment, got a few ideas at the least..

[naive pawn]

i think i was stuck on imagining them as an arbitrary plane unrelated to the origin and i couldn't figure out how that'd be represented with just 3 dimensions lol

[onyx geyser]

one of them of course, classicly being turning it into a float and seeing what that did (spoiler, it didn't work)

[sour fulcrum]

so my understanding of normals (someone can correct me if im wrong) is that each point on the mesh/collideretc. has a Vector3 normal value facing outwards from that position relative to the mesh

then the normal associated with the face of the contact is calculated based on the 3 normals that make the triangle face, relative to their positions

[muted sapphire]

Why is the position of my floor so specific? The cube directly above it is perfectly even, but 0,0,0 seems to be somewhere completely different now

[sour fulcrum]

then reflect samples the incoming direction and normal in order to rotate(?)(smarter word for this) the direction

[naive pawn]

yeah i get what they're supposed to be but "what do the values of the normal vector mean" was my question
like it can't be the absolute position at the tip or something like that since it wouldn't specify the tail

using the origin as the tail is pretty obvious in hindsight...

[naive pawn]

is it nested in anything? make sure selection mode is pivot instead of center

[muted sapphire]

again, i apologize for my stupidity, I nested two floor elements (to make the floor move) in a singluar bigger floor element which was created at visual position

meaning some really jank values

[onyx geyser]

well, it did something

so i'm wondering if i create a new float with a very specific number if i can fix this

[sour fulcrum]

sure

[onyx geyser]

though it doesn't seem to accept floats..

rb.velocity = Vector2.Reflect(rb.velocity, inNormal);

[muted sapphire]

i do hope you gave the zubat the collision of a circle

[onyx geyser]

this is what i came up with that caused whatever that was

it's progress

[sour fulcrum]

what does it accept

[onyx geyser]

the general things

[onyx geyser]

yeah i did

[sour fulcrum]

thats not a real answer 😄

[onyx geyser]

a few times it began spinning at the beginning, it was funny

[muted sapphire]

aand it seems that that was too much unity for my pc and its dying now

i guess that means a forceful break

[onyx geyser]

well, it accepts rigidbody, and itself

[muted sapphire]

oh my god

[sour fulcrum]

mouse over rigidbody.velocity and show

[muted sapphire]

does unity temporarily save to drives?

[onyx geyser]

linear velocity of a rigid body?

[naive pawn]

it shouldn't

why do you ask?

[muted sapphire]

because it complained about my disk being full despite it not actually being that when i checked after closing the program

[naive pawn]

did you put the project in a synced folder? ie onedrive

[muted sapphire]

the day i put anything i develop in real time into a synced folder call an exorcist

[naive pawn]

can you show the error

[muted sapphire]

no it was only once

[naive pawn]

it's gone now?

[muted sapphire]

it said something about trying to save to a disk drive with 0.00GB of space

it closed right after

[sour fulcrum]

Rigidbody2D.velocity is a Vector2

[naive pawn]

ah ghost errors

[muted sapphire]

am i haunted now

[naive pawn]

always have been

[onyx geyser]

so the idea i'm getting is that i can make a new vector 2 specifically for reflect that acts as it's own direction change?

[muted sapphire]

[onyx geyser]

it's own instance by chance?

[sour fulcrum]

yeah. but worth mentioning that you might be overthinking what "make a new vector2 specifically" might entail

[naive pawn]

-# puts on tinfoil hat you think we just shocked rocks into thinking? nahhh there's a spirit in there

[sour fulcrum]

Vector2 is a value type, like ints, strings, bools, floats etc.

its just a lil piece of datas

in this case two floats

[muted sapphire]

every copy of TestProject_2_Final is personalized

[sour fulcrum]

you can make vector2's whenever you feel like it

[muted sapphire]

value types are fun

[onyx geyser]

maybe public Vector2 vec = ?;

[sour fulcrum]

i hate to be this person but the answer to this is searching vector2 unity

gotta get into that habit

[muted sapphire]

why does unity even have a special value type for that

[sour fulcrum]

here's a freebie on the house
https://docs.unity3d.com/ScriptReference/Vector2-ctor.html

[onyx geyser]

wow

that's uh

a lot

[sour fulcrum]

why does Unity, the game engine have a dedicated Vector2 type?

[muted sapphire]

yes

it seems unnecessary to do that rather than just two floats

[sour fulcrum]

a vector2 is two floats

[muted sapphire]

or a float[] which is probably just what that is

[sour fulcrum]

i don't think it's an array

[muted sapphire]

yeah but at this point why call it vector2

[sour fulcrum]

it's a vector

with 2 values

[hexed terrace]

you need to do things with vectors that would become tiresome to keep tying out two floats..

[onyx geyser]

guess i can mess with the different vector2's

[muted sapphire]

eh, maybe, i dont know the oddities of unity further onward

maybe it does have some perks that only come into play later

[onyx geyser]

well i now know what negative does.

[sour fulcrum]

all your looking for is how to make new vector2's, all you gotta look for in there is that

[sour fulcrum]

100% genuine question cuz i know this will sound off, have you ever made a video game before?

[muted sapphire]

Yes

But not a good one

I can do the complete math behind a video game

And I can do the complete concepting

[sour fulcrum]

Handling concepts like positions, rotations, scale, directions etc. etc. without a easy Vector2 class would be nightmare-ish

[onyx geyser]

i'm half tempted to just mess with all of them, it's kind of entertaining

[sour fulcrum]

just wait till you find out Vector3 and Vector4 exist 😄

[onyx geyser]

oh god.

[muted sapphire]

yeah that was obvious

[onyx geyser]

i'm so far away from the project i WANT to be working on, this is evident

[muted sapphire]

same here

[sour fulcrum]

Remember, what you wanna build up isn't what you know, it's your ability to learn

[muted sapphire]

when does vector4 come into play though

[sour fulcrum]

biggest example is color related

[muted sapphire]

ah

[sour fulcrum]

(RGBA)

[muted sapphire]

was confused on why you were time travelling with objects

[hexed terrace]

have mostly seen Vector4's in shaders

[muted sapphire]

I feel like after Vector4 you should really just take a break tbh, I've once ended up with a 5-dimensional array when making a picture editor in Java for school and it made me rethink my whole concept

[sour fulcrum]

The stuff about directions and collisions and vector2's etc. your learning rn is great to learn in isolation but what you want to build up in the long run is the ability to learn these things yourself, by identifying what exactly you want, what you know, what you don't know and then researching those things

[onyx geyser]

makes me wonder just how difficult it'd be to make a kings field like

because that's the first 'step' towards the project i want to make

[muted sapphire]

Unitys documentation is unfortunately lackluster or at least has been in the corners i checked

[sour fulcrum]

Unity's documentation is really good tbh

far, far from flawless but like all things considered

it's samples can be lacking at time admittedly

[muted sapphire]

90% of it tries to mouthfeed me the things with a 30 minute video to explain a certain single line

and the other 10% are professional manuals that only help if you already know your stuff

[sour fulcrum]

if your seeing videos your not in the documentation lol

https://docs.unity3d.com/ScriptReference/index.html
https://docs.unity3d.com/Manual/index.html

[muted sapphire]

some docs pages had videos linked

but that was the weird corners

[sour fulcrum]

manual stuff might have some if applicable

api doesnt

[muted sapphire]

that was genuinely the hidden page that will make my life so much easier

thank you

somehow nothing links to that page

[sour fulcrum]

This just isn't remotely true but I'm glad you know about it now 😄

[muted sapphire]

None of the pages I found did at least

all documentations linked to were either third party and sucked or a weird corner of that page

[sour fulcrum]

and then if you click that first link

[hexed terrace]

Or clicking the litle ? on components will take you directly to the docs page for that component.

If the pg doesn't exist when you click that, it's (probably) because it's not a Unity component

[muted sapphire]

only thing i found was people trash talking it

now i have it though so its fine

as long as its decent

[hexed terrace]

it's alright

[simple hawk]

``using System.Collections;

[sour fulcrum]

there is a mistake in this code that would make it fail to compile

[simple hawk]

I'm using this code to fire a bullet from a gun, I added somw extra bits at the bottom to destroy the bullet after some time to make suure they don't stay for too long, but I'm not sure the Destroy part is correct

[muted sapphire]

that doesnt seem right

isnt that missing a (

[simple hawk]

ur right, now it's saying this

[muted sapphire]

i think its telling you that you cant do Destroy.something

you have to do something.Destroy

[sour fulcrum]

google "Unity Destroy Function"

[onyx geyser]

rahgg

[muted sapphire]

just a wild guess

[onyx geyser]

rb.velocity = new Angle(inNormal * 90);

i wanna say something like this might be close

[eager spindle]

GameObject.Destroy is a static method taking in a GameObject.

You can do Destroy(gameObject).

[sour fulcrum]

Angle isn't anything

what is rb.velocity

[leaden pasture]

I also can't see any references to gulletPrefab so presumably that's meant to be bulletPrefab?

So you'd need to do Destroy(bulletPrefab)

[muted sapphire]

but you cant do Destroy.something is what i was trying to say

[simple hawk]

yea, that helped, thnx guys

[eager spindle]

Yes

[muted sapphire]

the arch nemesis of any coder

spelling

[onyx geyser]

i'm confused and i think the coffee is fading

i may have to sleep on it

[leaden pasture]

Though, that said, that's probably still inadvisable right? If bulletPrefab is the prefab itself. Would you not be wanting to destroy the spawned object instead of the actual prefab? Iirc destroying an actual prefab causes issues as well

[muted sapphire]

it means that youre trying to create an instance of type Angle which isnt really a thing if i understood correctly

[onyx geyser]

that seems right

[sour fulcrum]

if you give birth your not creating a timmy, your creating a baby named timmy.

Making something requires the Type

eg. new Vector2(newXValue,newYValue)

[eager spindle]

rb.velocity is the velocity of the rigidbody. It's represented by a Vector3.

If a rb's velocity is (1,0) it moves along the x axis at 1 unit per second.

A velocity has nothing to do with an angle

[naive pawn]

if you don't have a solid idea of what you want, write out what you do know instead of putting in random guesses like that

[sour fulcrum]

this is rigidbody2d so all of these are vector2's

[sour fulcrum]

velocity is absolutely related to angles

[simple hawk]

huh, that makes sense, how else would I do it? I'm not sure how it works with a prefab

[sour fulcrum]

that's what velocity is

[eager spindle]

you can't assign an angle to a velocity

[muted sapphire]

velocity is distance per time, it doesnt contain an angle

its just speed

[leaden pasture]

You'd need to assign a reference to your spawned object. You're destroying it outside of the local scope so id probably add a

'private GameObject activeBullet' under where you initialise the bulletPrefab. Then you can do

'activeBullet = Instantiate(bulletPrefab, `...

Then destroy activeBullet instead

[sour fulcrum]

distance in what context 😄

[naive pawn]

no, velocity has a direction whereas speed does not

[muted sapphire]

velocity having a direction feels very very wrong

[naive pawn]

that's how it's defined

[leaden pasture]

I mean. All vectors have direction. That's what a vector is. Magnitude & direction

[sour fulcrum]

velocity is a direction

[muted sapphire]

oh s**t velocity is vectoral

[naive pawn]

speed is always positive
1d velocity can be negative - speed is the magnitude of velocity

[muted sapphire]

my bad my teacher just lied to me like two weeks ago

[eager spindle]

It's kinda weird because people say the speed of an object is x m/s, but don't specify the direction

So people think speed is a single number

[naive pawn]

it is though

[eager spindle]

People confuse it with velocity

[muted sapphire]

speed is non directional

[onyx geyser]

so what am i doing

[muted sapphire]

velocity is directional appearantly

[naive pawn]

speed is just |v|

[sour fulcrum]

imagine your falling, you might have a velocity of (0,-5,0). the direction is the line from 0,0,0 to 0,-5,0

[muted sapphire]

yeah i know

i looked it up

i was just taught differently for some reason

but velocity being directional makes sense

[naive pawn]

step back and think about what you want to achieve first
break that down into parts, and figure out the "how" from there

[onyx geyser]

that's a frustrating answer, because i know what i want, i can't figure out the how because i'm still super new, i don't know how to apply everything yet.

i want the ball to bounce off a wall at 5 degrees so it doesn't get stuck bouncing half way.

[naive pawn]

5 degrees from what?

the normal or the surface?

or the incoming angle?

[onyx geyser]

the normal presumably, that's what's this has been all about

[naive pawn]

gotta get precise with your goals before you can break them down

[onyx geyser]

if i knew every term under the sun then yes i would probably break them down, but that's why i'm in here, to learn how to break them down.

[naive pawn]

nah don't presume, you have to decide right now
try drawing out a diagram of what you want to happen if you aren't sure of the terms

[teal viper]

We can't help you with something you're not sure about yourself.
Why do you need it to bounce at such a specific angle?

[sour fulcrum]

(feel like this might be a "see you at 3" vs "see you in 3 hours" typa situation)

[onyx geyser]

the image on the left is what i want to happen, the red being what i don't want to happen.
the image on the right is an accurate representation of what IS happening.

[naive pawn]

so what's the 5 degrees thing here?

[onyx geyser]

[muted sapphire]

I was about to ask too

the red line you drew in the left image are 5 degrees off 90°

the blue line doesnt really match up with anything

[sour fulcrum]

they want the rb to not get stuck in an infinite bounce cycle i believe

[naive pawn]

i thought you already had reflection off the normal

[sour fulcrum]

they have it but don't know how to use it

[onyx geyser]

just pretend that it's 5 degrees, i never intended for it to be so specific, just that i need the angle to change so it doesn't get stuck.

i'd even take a slight change over what's happening now

[naive pawn]

you have a Vector2 representing a direction (velocity), you pass it through reflect, you get a new direction that you can assign back to the velocity, no?

[sour fulcrum]

do you want the angle to be 5 degrees, or do you want the angle to be an additional 5 degrees?

[onyx geyser]

an additional

[naive pawn]

yeah 5 degrees is wayyy less than that lol - if you don't want specifics, don't state specifics

[sour fulcrum]

your previous messages say the opposite. not pointing out as a gotcha but as an example of why you gotta be clear

as they are different things

[naive pawn]

additional 5 degrees towards the surface after reflection?

[onyx geyser]

gods sakes give me a moment to collect my remaining cells

the coffee is thinning out and it's 4:30 am

when it hits the wall, i want to add a value to it's direction, so that it shifts slightly enough every time it hits that it will NEVER get stuck, that and it should theoretically add a bit more unpredictability to the ball itself.
so if it hits the wall at a 90 degree angle, it'll leave at 95 OR 85.

instead of going up and down

like it has been

is this clear enough

[sour fulcrum]

yeah that's a lot more explicit

[onyx geyser]

in trying to make this dudes tutorial make sense i've spent the last 4-5 hours making pong

i might as well as follow the 35 hour tutorial instead

[naive pawn]

you're gonna have to do some trig here

or i guess quaternions is the other options

basically:

• reflect the incoming velocity along the normal
• turn that velocity from x, y into r, theta (magnitude + angle) with one of:
  • Vector2.SignedAngle (deg)
  • Mathf.Atan2 (rad)
• change the theta
• turn that r, theta back into x, y (Vector2) with one of:
  • Quaternion.Euler (deg)
  • Mathf.Sin/Cos (rad)
• assign that back to velocity
  you can mix rad/deg but you'll have to add the conversion factor Rad2Deg/Deg2Rad

does that make sense

[onyx geyser]

unfortuntely not, there is a few things i recognize

[naive pawn]

well, ask away about the parts you don't

[onyx geyser]

are you sure.

[naive pawn]

you can ignore the Mathf/Quaternion stuff for now, that's more of impl details

[sour fulcrum]

(if its like 5am you might wanna sleep)

[naive pawn]

make sure you understand the overall flow first

[naive pawn]

oh yeah, that too

[onyx geyser]

(i'm too stubborn, i am going to make this ball bounce at an akward angle whether i like it or not)

[naive pawn]

that's ok, but it doesn't have to be right now

[sour fulcrum]

this wouldn't let you specify a specific angle but to solve the problem you could probablyy poke the normal value abit before passing it into reflect right?

[naive pawn]

you would be able to specify an angle offset in the "change the theta" step

[onyx geyser]

so from the point i'm at, i have
Vector2 inDirection = rb.velocity;
Vector2 inNormal = collision.contacts[0].normal;
Vector2 vector = Vector2.Reflect(inDirection, inNormal);

where does this fit into the rest of this equation, because this IS a step in the right direction

at least from what i know

[sour fulcrum]

(i meant my solution wouldnt be able)

[onyx geyser]

i want to find out where this sits so i can base my questions around this

[naive pawn]

im not sure what your solution is, i wasn't following too closely in your convo earlier

[naive pawn]

right now you have the reflected x,y velocity, step 1 is done

[onyx geyser]

ok, so what is a theta

how is a theta used

[naive pawn]

theta is a greek letter that's commonly used to represent angles (some others are also used - alpha, beta, gamma, phi, can also represent angles)

the important thing is that we're changing the representation from x, y (cartesian) into a magnitude and an angle (polar)

are you familiar with the polar coordinate system?

[onyx geyser]

nope!

[naive pawn]

cool, try looking that up
you don't need to understand the math behind it just yet, just an overview of how it represents points

[onyx geyser]

while i'm doing that, what do you mean were changing x and y into magnitude and an angle

[naive pawn]

try looking up the polar coordinate system, i think it'll help illustrate

[onyx geyser]

it's made to determine a specifc point by taking two other points?

i assume this is a pretty important piece of math for programming as a whole judging by the way it looks

[naive pawn]

it's a system of coordinates like the cartesian x,y system, it just uses different values instead of x,y

[onyx geyser]

ahh, ok i think i got it

as much as i can right now anyways

it's a lot like planning coordinates right?

so what were doing in this case is finding the coordinates of the ball and then shifting those coordinates? do i have that right or somewhat close?

[naive pawn]

not sure what you mean by that

[onyx geyser]

like when you're looking for a specific location on a map, you'd find the coordinates in a grid using a set of numbers

[naive pawn]

we're finding the coordinates of the velocity since that's the thing we want to modify
we aren't changing it in this step, just converting it to a different system

[onyx geyser]

right, were just finding it

[naive pawn]

like how 1 meter and 3ish feet have the same value, just expressed differently

[onyx geyser]

so the first step was reflecting, and now were finding the velocity in which it bounces from that wall? or where it will go once it bounces off since this takes place afterwards?

[naive pawn]

oh you mean lat/long?
well that is certainly a separate system, i don't think that's super comparable to polar coords though

[onyx geyser]

rrah

[naive pawn]

(x=0,y=1) and (r=1, theta=90°) are the same point, but expressed in different systems

[onyx geyser]

oh ok i see i see

[naive pawn]

in the first, it's saying "go to the right 0 units, and go up 1 unit"
in the second, it's saying "go to the right 1 unit, and rotate that counterclockwise by 90°

[onyx geyser]

that's weird and complex

but i'm following

[naive pawn]

first step is finding the outgoing x,y velocity
second step is turning that into r,theta

basically we want to modify the angle, but there's no angle to modify with the x,y representation
so we convert it to something that does have an angle, modify that, and then convert it back

[onyx geyser]

oh ok so that's the point of it being such a confusing mess

for conversion

so at the point of the code, how exactly did we come to find the x y? outside of using reflect, does the program now know what they are internally thanks to these 3 lines?

[muted sapphire]

so far so good

[onyx geyser]

oh hey temple run

[naive pawn]

the outgoing x,y right now is just the reflection of the incomong x,y, which we can retrieve from the rigidbody directly

[muted sapphire]

about that but bigger is the idea

[onyx geyser]

so even if i don't see it or have a clue what it is, it DOES exist

[naive pawn]

@sour fulcrum was your solution the OnCollisionEnter thing
im coming to realize ive had this discussion before with someone else and the issue was the collision had already happened and the velocity had changed, was that what you were referring to

[onyx geyser]

those being inDirection and inNormal, which didn't have an autocorrect yet are still correct

yep that was what we were talking about

that the collision happens and then we make the change

[naive pawn]

they didn't have autocorrect because they didn't exist at that point - you created them

[onyx geyser]

i'm a father!!

[sour fulcrum]

but i was suggesting maybe to get kinda roughly ok results you could maybe just offset the normal from the contact point

[naive pawn]

the issue is more that the collision already happened though isn't it

[sour fulcrum]

nah Sila was just misunderstanding that we dont want to change the direction the collision caused, we want to give a new direction after it happened

[onyx geyser]

yep

[naive pawn]

ah ok i see

i suppose what im referring to is a new issue then?

once you get the normal of the collision, the rb velocity has changed so you wouldn't be able to get the incoming velocity

[onyx geyser]

i think we wanted to get the outgoing velocity and change that

[naive pawn]

or is Collision2D.relativeVelocity the incoming velocity?

[onyx geyser]

which is why it was important to have velocity, from my understanding

🤷‍♂️

[sour fulcrum]

so you are right in that that value is wrong and im a dumbass

but we didn't get to actually using that yet so im glad it was caught now 😄

[naive pawn]

aren't we all

i should test that

[sour fulcrum]

im 6 years deep into unity but with no formal educational in math so i have unpredictable blind spots when it comes to this aha, apologies

[onyx geyser]

so uh.. what next then

what're we doing

because it sounds like the direction shifted?

[muted sapphire]

How can i turn three float values into a Vector3? I'm unfamiliar with C# around that corner, especially with Vector3 being an unity specific class

[clear juniper]

Vector3 newVector3 = new Vector3 (x, y, z); where x, y, and z are your three floats 🙂

[muted sapphire]

ah, the usual

thank you

[naive pawn]

just to get you on the same page:
there's 3 velocities involved here

• the incoming velocity
• the outgoing velocity calculated from the collision
• your custom outgoing velocity
  the last one is what we're trying to build, and it relies on the incoming velocity
  but in OnCollisionEnter2D, rigidbody.velocity is now the second one - we don't want that

[naive pawn]

yeha you should just check docs for this sort of thing

[sour fulcrum]

(and this is where you could have found this info for future ref)

[muted sapphire]

yeah, thank you, I didn't think it was this easy tbh

[naive pawn]

also fyi some unity apis have overloads to accept 3 floats or a Vector3, so if you're using one of those you don't have to make a Vector3

[onyx geyser]

with incoming being inDirection
the outgoing being inNormal
and the third being something else?

[sour fulcrum]

i learnt c# before python and the only thing i really learned about python is how much i don't like python 😄

[muted sapphire]

would be nice, however i need to set transform.position which is a Vector3

[muted sapphire]

agreed

[naive pawn]

the third is the one we're trying to make
inNormal is none of these

[muted sapphire]

Python does too much for me which makes debugging hell

[onyx geyser]

understood understood, so i don't have the incoming outgoing velocity yet

[clear juniper]

if I understand the aim correctly, can you not just do

void OnCollisionExit2D (Collision2D collision)
{
    ballRb.velocity = Quaternion.Euler (0,0,Random.Range(-5, 5)) * ballRb.velocity;
}```

or have I missed something

[naive pawn]

to be clear you don't need the calculated outgoing velocity
you need the incoming velocity, and you build your custom outgoing velocity with that
problem being, not sure if we can get incoming velocity easily - might be collision.relativeVelocity, but i'll test that before confirming

[naive pawn]

something something unity physics not deterministic...

[onyx geyser]

for the sake of i'm curious, i'm gonna see what happens

yeah nothing happened

[clear juniper]

something should happen lmao, change it to -50 and 50?

[clear juniper]

surely determinism really does not matter here lmao

[onyx geyser]

it works

kind of

it runs into the issue of sometimes not going the right direction after bouncing off a wall but other than that

it works.

how

how does this black magic work that i've spent the last several hours learning about?

idk if it's a normal feeling but seeing someone pop out of the woodworks with a code that works as it is needed after spending several hours prepping for an exhaustive process of math is definitely a unique feeling.

[clear juniper]

all that code does is rotate the velocity in the z direction randomly between -50 and 50 degrees. A negative value is anticlockwise, a positive value is clockwise, so you never actually need to work out the maths

and OnCollisionExit happens after the collision, so it's your final exit velocity that it is rotating!

[onyx geyser]

i think i know why this is one of maybe 8 emotes on the server now

[clear juniper]

being able to rotate vectors is a really handy trick to have in your game dev toolbelt 🙂

[onyx geyser]

because that is the exact feeling i feel upon see that this works and i didn't need to do a ton of guess work and find the normal and edit it.

[clear juniper]

rotatedVector = quaternion * originalVector

yeah I get the feeling lol

[onyx geyser]

that being said, it's now being added to the notebook

and i now need to go back through and make a ton of edits, because despite the fact that several hours of work could've been solved if i knew what a quaternion was, i still learned a lot

alright i'm going to bed..

[clear juniper]

good night 🙂

[onyx geyser]

i got to be up at before 1 pm for a doctors appointment

see if i can't get prescribed some Adderall

[naive pawn]

according to praetor and nav relativeVelocity is indeed the incoming velocity fyi

[onyx geyser]

good to know

thanks for helping me so much, i really appreciate it @sour fulcrum, you too chris

[onyx geyser]

you too, thanks, saved me another 2 hours, nigh nigh

btw, before i flat out disappear, i'd like to let you all know this is my wallpaper on my computer, my motivation for my project, and exhibits truth every time i look at it.

[muted sapphire]

Any ideas why this is never called? My parent object can ram the Cylinder named "Enemy" with tag "Obstacle" without getting to the debug statement

It never even makes it into the collision enter

[fickle plume]

You need to debug up the chain.

• is it getting called at all
• are you using proper physics methods in FixedUpdate to move objects if it's not
  etc.

[muted sapphire]

I was hoping that this would be triggered simply by two collision boxes touching each other

but this doesnt seem to be the case

[naive pawn]

does one of them have a rigidbody?

[muted sapphire]

No

[naive pawn]

yeah you need one

rigidbody is what drives physics

[muted sapphire]

I have the premade box collider and the capsule collider

[fickle plume]

https://docs.unity3d.com/ScriptReference/Collider.OnCollisionEnter.html

[muted sapphire]

"this collider/rigidbody"

[naive pawn]

https://unity.huh.how/physics-messages/collision-matrix-3d

[muted sapphire]

they both have colliders

which is why i was hoping itd work

[naive pawn]

one needs to have a rigidbody

[fickle plume]

read the rest as well

[naive pawn]

"when this collider has begun touching another rigidbody"/"when this rigidbody has begun touching another collider"

[muted sapphire]

Sorry, my app didnt even show me you sent a link lol

[muted sapphire]

Ill give the player a rigidbody rq

[fickle plume]

Since you were moving it by transform you need proper physics movement as well

[muted sapphire]

okay it works now

thanks

[muted sapphire]

my player thankfully barely moves at all

went with the method of having the ground move below instead

[trail heart]

I don't think Rigidbody physics are designed to accomodate that kind of situation

[muted sapphire]

it works

except for the fact that the player doesnt get deleted when in the middle lane for some reason

only when in left lane, right lane, or transition

unsure what thats about but eh

I correct, it seems to not work when static

[fickle plume]

Even with kinematic rigidbody you still want to use Rigidbody.MovePosition so it updates properly in step with physics update. Teleporting transform will put some frames inside collider before hit registers.

[muted sapphire]

whenever NOT moving my character, the collision never occurs

only when going left or right it does

[naive pawn]

you probably need a dynamic rb on the thing that's moving

[muted sapphire]

alright done

[clear juniper]

nah not necessarily, dynamic rigidbodies are for things that physics should move

[fickle plume]

You might be looking for https://docs.unity3d.com/ScriptReference/Collider.OnCollisionStay.html instead?

[muted sapphire]

well, now my character has tremors

[clear juniper]

is your camera moving?

[muted sapphire]

no

[clear juniper]

can you record it and show your code?

[muted sapphire]

gladly

let me quickly see if i can make my character actually move properly again though

a part of my code that i had before doesnt like the rigidbody moving

[clear juniper]

oh can you screenshot your rigidbody too please?

[muted sapphire]

its almost unaltered but sure

[fickle plume]

make sure it's kinematic, if you replacing transform move

[clear juniper]

yeah that was my thought

[muted sapphire]

setting it to kinematic made it still have tremors but also not have collision at all anymore

[clear juniper]

yeah you'll need to enable full contacts

by default, unity disables collision messages for kinematic/kinematic collisions and kinematic/static collisions

kinematic/static also happens for any object that has a collider and no rigidbody, unity treats those as static

[muted sapphire]

the tremors come from following

my transitions between lanes are done by checking if the player is in the correct lane and if not, moving them by speed into the target lane

somehow, the rigidbody seems to leave the middle lane ever so slightly enough that it goes too far

it surprisingly worked just fine when i used transform.Translate but the problems with that were long predictable

Might have to embed something for rounding down

[clear juniper]

can you paste your movement code here? 🙂
```cs
// your code
```
will format it like this:

// your code

or use something like https://paste.myst.rs if it's more than 100 or so lines

ignore the VERY clunky catcher in the middle

its a work in progress

trying to make it not shiver

[clear juniper]

it's not going to fix anything, but instead of void Update () you should use void FixedUpdate () when you're doing things with rigidbodies 🙂

[muted sapphire]

May i know what the difference is?

does it use time rather than frames?

[clear juniper]

FixedUpdate is when physics updates happen

it happens once every 0.02 seconds exactly (or rather, it tries to), where Update happens as soon as it can

[burnt vapor]

FixedUpdate is a static interval. It doesn't invoke every frame, rather it is a set number of invoked regardless of your FPS

[muted sapphire]

well, my character still has tremors but now i cant move anymore

[burnt vapor]

So it's perfect for physics given that they will always have a reliable result

Important to note that if you don't rely on reliable output like this, you should just use Update. Perhaps you need it regardless, and pair it with Time.DeltaTime

[clear juniper]

oh, you're polling input in there too - my bad 😂 input needs to be done in update, for now just change back to Update 😅

[muted sapphire]

assumed as much

WasPerformedThisFrame doesnt really add up when its not called once per frame

I should probably begin seperating scripts

[clear juniper]

motion.MovePosition(transform.position + new Vector3(laneChangeSpeed, 0, 0));

this here should be changed to

motion.MovePosition(motion.position + new Vector3(laneChangeSpeed, 0, 0));

using motion.position instead of transform.position - again I don't think it will fix it, but it might do. Transform position and rigidbody position can get desynced

there are also a few places where you're setting transform.position instead of motion.position

[muted sapphire]

when i say tremors

it goes a lot faster than that, the frame rate of the recording just isnt that high

[clear juniper]

yeah everywhere you use transform.position, change it to motion.position

[muted sapphire]

ah

oh yeah that worked

let me see if i need the catcher even or if its got itself

wait, it calls that 100 times a second, correct?

[clear juniper]

whatever the FPS is per second

so if the FPS is 100, it'll do it 100 times a second

[muted sapphire]

ah damn i use update not fixed update

[clear juniper]

tbh that's fine for now

don't worry too much about it - ignore what I said 😂

[muted sapphire]

DAMN YOU INPUTS

[clear juniper]

Update is FPS times per second, FixedUpdate is 50 times per second - which is why you didn't receive input

[muted sapphire]

figured that

[clear juniper]

you're actually using the new input system, a better way is probably to use events

[muted sapphire]

can you lock fps in settings? it would be kinda cool for later since im planning to make this for mobile

[clear juniper]

you can!

not in settings, it's Application.targetFrameRate = 60;

[muted sapphire]

ah yes, thanks

Although I am gonna have to figure out how to make it both compatible with 60 and 120 FPS

but thats a question for later

alright it works just fine now, even statically

[burnt vapor]

Note that this is unreliable

This value does not guarantee 60fps. It might get ignored altogether

[muted sapphire]

now onto further features

[burnt vapor]

Also depends on Vsync

[clear juniper]

a better way would be to add the PlayerInput component to your cylinder, then in this script you do

void OnLaneLeft (InputValue val)
{
    if (lane > 1)
        lane -= 1;
}

void OnLaneRight (InputValue val)
{
    if (lane < 3)
        lane += 1;
}```
then remove the lane changing code from update

[burnt vapor]

Especially with this

targetFrameRate might not even work on mobile. A lot of devices don't allow you to set a target

[muted sapphire]

amazing

i love mobile development

but again, thats something i can deal with later

[burnt vapor]

Comparing to other devices, xbox and playstation have hardcoded defaults. You know how ps5 has a performance mode that allows up to 120 FPS?

[muted sapphire]

yeah

[muted sapphire]

what calls "OnLaneLeft"?

i mean, how do i make my input call that

[clear juniper]

the PlayerInput component 🙂

https://docs.unity3d.com/Packages/com.unity.inputsystem@1.5/manual/PlayerInput.html

[muted sapphire]

oh component

my head was persistently thinking of library

[clear juniper]

ah yeah 😂 it's just a component, by default it uses SendMessage to call OnLaneLeft. You'll get a little info box under the "behaviour" dropdown on the PlayerInput component which will tell you the exact name, but I'm 90% sure that's right if it is called "Lane left" in your input actions asset

[muted sapphire]

I'll take all the things i had in global actions and instead put them into the playerinput components own thing

[clear juniper]

yeah you're basically doing input the most difficult possible way 😂 not your fault, all the tutorials are based on the beta version of the input system 🙃

PlayerInput component is great

[muted sapphire]

documentation is for noobs

here, we just randomly click buttons and write stuff until it does what you want it to

alright it all works now, let me do jumping and crouching

what does the rigidbodys "use gravity" do, exactly? can i just use that to boost it up a little when i press jump

[clear juniper]

use gravity means it will continually fall down - but only when the rigidbody is "dynamic"

dynamic basically means unity calculates the position and movement based on forces - which is not what you want

[muted sapphire]

So what you're saying is i have to do gravity myself?

aww i dont wanna have to deal with another collision

[clear juniper]

yep! 😁 it's fairly straightforward though, and you don't have to deal with collisions - the rigidbody will sort that for you

[muted sapphire]

is there a command to check when my character is on the floor?

[hexed terrace]

not built in, no

[clear juniper]

all you'll want to do is keep track of a float _verticalVelocity, and add Physics.gravity.y to that every FixedUpdate. When you do MovePosition, use _verticalVelocity instead of 0 in your Vector3. Then when you jump, you set that velocity to some value, and your character will jump!

for checking when you're on the floor, you can raycast downward

[muted sapphire]

i kid you not just when you wrote that i made a yvelocity variable

[clear juniper]

if (Physics.Raycast(motion.positon, Vector3.down, 0.1f, LayerMask.NameToLayer("Floor")))
    // you're on the floor! Assuming your floor is on the "Floor" layer

0.1f there is the distance of the raycast

[hexed terrace]

you'd most likely also want to check the layer of the thing that's been hit

[clear juniper]

yeah

updated the snippet to do it the most simple way for now 🙂

[muted sapphire]

i feel like im gonna have to add a factor to that gravity

[clear juniper]

it's just using the gravity setting in project settings!

[muted sapphire]

one frame and my player is GONE

[clear juniper]

oh yeah you're moving with MovePosition

[muted sapphire]

oh wait its going upward

wtf

[clear juniper]

you'll want to multiply it by Time.fixedDeltaTime sorry 😂

[muted sapphire]

forgot a minus there

[clear juniper]

huh, I could've sworn MovePosition works with collisions

[clear juniper]

okay, you'll need to set your velocity to 0 when you're on the floor

[north kiln]

This is incorrect, you're passing a layer not a layer mask

[clear juniper]

isn't a layermask with a single layer the same value?

[north kiln]

https://unity.huh.how/physics-queries/layer-masks

No

[clear juniper]

huh

TIL

thought it was a shortcut to make the explanation a bit more straightforword. My bad 😂

[naive pawn]

it doesn't, no

[naive pawn]

31 as a layer -> 32nd layer
31 as a layermask -> layers 1-5

[clear juniper]

should perhaps stop advising on things I rarely use 😂

[muted sapphire]

So what do i put instead?

[clear juniper]

up at the top you want a public LayerMask floorLayer;

then set it in Unity to the layer your floor is on (which should be different to the layer your player is on)

layers are up by the name of the gameobject 🙂

[muted sapphire]

then what do i put in the if statements?

[clear juniper]

if (Physics.Raycast(motion.positon, Vector3.down, 0.1f, floorLayer))
{
    yVelocity = 0;
}```

that should stop you falling through the floor!

[muted sapphire]

let me just

doesnt work properly

oh wait

i should put floorLayer somewhere shouldnt i

yeah change LayerMask.NameToLayer("Floor") to floorLayer that was my mistake!

and maybe change cs yVelocity = 0;
to

you mean in case it stops jumps otherwise

did you set the floorLayer in unity?

yes

Set the object "Floor" and it's children "Floor1" and "Floor2" to layer "Floor" and then set floorLayer to Layer "Floor"

        {
            yVelocity = jumpStrength;
        }
    }
``` does this change anything?

I've moved a couple of things around, I can explain in a sec

[muted sapphire]

Oh yeah i can use fixedupdate now, thanks for the reminder

[muted sapphire]

no, still falls through the floor

[clear juniper]

• put everything in fixedupdate
• move yVelocity -= Physics.gravity.y; to the top of fixed update
• don't do a raycast for applying gravity
• move the final position change to after setting y velocity to 0 if you're on the floor

can you check if the raycast ever triggers in fixedupdate?

[muted sapphire]

it does not

[clear juniper]

what happens if you change the 0.1f to 0.6f

[muted sapphire]

what does that 0.1f do

nope still nothing though

yk what, i think im just gonna take a break

[clear juniper]

yeah that's reasonable 😂

[clear juniper]

it's the length of the raycast! So it goes 0.1/0.6 units down

[muted sapphire]

ah, i see

how can so simple things be so hard

i was planning to do so much but if that already causes so many problems i fear for myself

[clear juniper]

it's difficult to help over the internet, unfortunately! You get used to it though

I just wanna rewrite the whole thing the way I'd do it, but that would be helpful for nobody xD

[hexed terrace]

If the pivot is in the center of the player, that 0.1f won't be long enough

[thorn galleon]

Where can i find the anchor presets are in 6.0? I'm not seeing it in rect transform like shown in some tutorials

[clear juniper]

can you show a screenshot?

[clear juniper]

ah it needs to be a child of a canvas!

you need a gameobject that has a Canvas component on it, and your UI has to be a child of that

[thorn galleon]

thanks, that brings me to my next issue, i created that GameObject at the bottom there, but its not letting me resize it to the UI, im pretty new to unity, so im still trying to familiarize with everything

[slender nymph]

you should check out the documentation pinned in #📲┃ui-ux to learn how the canvas component works

[rough sluice]

Can someone tell me that why controls are weired?:
PlayerOneController.cs:

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

[RequireComponent(typeof(CharacterController))]
public class PlayerOneControl : MonoBehaviour
{
    [SerializeField] float _speed = 25.0f;
    [SerializeField] float _jumpSpeed = 8.0f;
    [SerializeField] float _gravity = 20.0f;
    [SerializeField] float _sensitivity = 5f;
    CharacterController _controller;
    float _horizontal, _vertical;
    float _mouseX, _mouseY;
    bool _jump;

    void Awake()
    {
        _controller = GetComponent<CharacterController>();
    }

    void Update()
    {
        _horizontal = Input.GetAxis("Horizontal");
        _vertical = Input.GetAxis("Vertical");
        _mouseX = Input.GetAxis("Mouse X");
        _mouseY = Input.GetAxis("Mouse Y");
        _jump = Input.GetButton("Jump");
    }

    void FixedUpdate()
    {
        Vector3 moveDirection = Vector3.zero;

        if (_controller.isGrounded)
        {
            moveDirection = new Vector3(_horizontal, 0, _vertical);
            moveDirection = transform.TransformDirection(moveDirection);

            moveDirection *= _speed;

            if (_jump)
                moveDirection.y = _jumpSpeed;
        }

        float turner = _mouseX * _sensitivity;
        if (turner != 0)
        {
            transform.eulerAngles += new Vector3(0, turner, 0);
        }

        if (looker != 0)
        {
            // action on mouse moving right
            transform.eulerAngles += new Vector3(looker, 0, 0);
        }

        moveDirection.y -= _gravity * Time.deltaTime;

        _controller.Move(moveDirection * Time.deltaTime);
    }
}

[clear juniper]

I suspect you've attached this to the player object, so it is rotating the player up and down. You probably want to make the camera a child of a separate object that is a child of the player so the hierarchy is

• Player
  • CameraArm
    • PlayerCamera
  • Body
  • etc

then in your code, cs if (looker != 0) { // action on mouse moving right cameraArm.eulerAngles += new Vector3(looker, 0, 0); }

where cameraArm is a public Transform cameraArm that you set in Unity 🙂

[fervent abyss]

hey guys, i have an issue that i cant seem to resolve
basically, i have a radar item in my game, that you can equip to track distance between you and the monster
the player has a radar script, that holds reference to the player head
the monster has a script MonsterLocation located on its body, with an instance so i can access its body transform like instance.transform.position, and it sets the instance when the monster is spawned

so basically the issue is:
if you equip the radar BEFORE the round starts (before the monster is spawned), it works fine and shows proper distance

but, if you equip the radar AFTER the round started (aka after the monster has been spawned), it shows a constant value of like ~0.5m, and never changes

here are the scripts. also the monster is spawned as a networked prefab because its a multiplayer game

using System;
using TMPro;
using UnityEngine;
using UnityEngine.XR.Interaction.Toolkit;

public class Radar : MonoBehaviour
{
    [Header("Player")]
    [SerializeField] Transform playerLocation;

    [Header("UI")]
    [SerializeField] TextMeshPro distanceInfo;

    void Update()
    {
        if(MonsterLocation.instance){
            distanceInfo.text = $"Distance:\n{Vector3.Distance(playerLocation.position, MonsterLocation.instance.transform.position):F1}m";
        } else {
            distanceInfo.text = "Distance:\n?m";
        }
    }
}

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

public class MonsterLocation : NetworkBehaviour
{
    public static MonsterLocation instance { get; private set; }

    public override void Spawned()
    {
        base.Spawned();
        instance = this;
    }
}

like if someone could help cuz i cant fix ts somehow 💀

[naive pawn]

sounds like it's grabbing a stale MonsterLocation.instance, maybe?

try logging its position

[fervent abyss]

doesnt it set a new instance everytime new monster spawns

[fervent abyss]

its somehow basically the same position of the player, not the monster

[naive pawn]

try logging something in that Spawned

see if it's triggering when you don't want it to

[fervent abyss]

okay

[fervent abyss]

same thang

[naive pawn]

same as what?

[hardy bobcat]

Hey all, dunno if this is the right place to ask, but is there really not any way to limit the framerate in the editor? I tried to limit the unity editor framerate externally using the NVIDIA control panel, but doesn't seem effective

[fervent abyss]

player position

like player pos = monster pos

[naive pawn]

ok, but does it log when it shouldn't

when is it logging - only when the monster spawns? does it log more than that?

[polar acorn]

It looks like you're doing a sort of singleton pattern, there should not be more than one of these. instance is shared across the entire project.

[naive pawn]

if you're referring to gameview you could use Application.targetFrameRate to mark a target, but it's not exactly a limit

[fervent abyss]

do i like instance = null on despawn basically

[polar acorn]

If there's more than one MonsterLocation, you don't use instance at all

You reference the one you actually want directly

[fervent abyss]

theres only one tho

[hardy bobcat]

I've had luck doing it in gameview, I'm looking for a way to do it in the editor, since I have the editor open quite a bit, while doing stuff and my video card is absolutely flying

Does closing the scene tab do anything?

[polar acorn]

So then it shouldn't be spawning more than once, right?

[fervent abyss]

yeah

[polar acorn]

Probably best to just set instance in Start or Awake then

[fervent abyss]

i tried, its literally same result

[polar acorn]

Put a log when you set instance. Ensure that log only prints once. Try logging the name of the object it's on as well

[real grail]

What you are doing is this:
This is basically a Singleton Setup

public class MonsterLocation : MonoBehaviour
{
    public static MonsterLocation instance;

    void Awake()
    {
        instance = this;
    }
}

Witch means there is only one of these in the scene.

If there is no Monster at the start.
Then in your Radar Script in Update:

MonsterLocation.instance should be null idk how is that not showing on your console for error if there is no moster at the begining.

[fervent abyss]

i mean it checks if its null or not

[naive pawn]

well it apparently isn't

[real grail]

can you log MonsterLocation.Instace and see what it gives you ?

[fervent abyss]

okay

[fervent abyss]

it gives the object name of where its located, but if i try to log MonsterLocation.instance.transform.position, it shows my player position for some reason, not the monster....

also when the monster is despawned after the round, it shows this

[sour fulcrum]

no, if you are logging monsterlocation.instance.transform.position, you are logging the monsterlocation position

[polar acorn]

Can you show a screenshot of your player object after the log shows the player's position

[polar acorn]

Because it's null. The object you were using for instance is destroyed but you're trying to still use it

[fervent abyss]

i know

[fervent abyss]

Bone - monster body

[polar acorn]

Is that the object whose position is being logged? Maybe log the name of the object as well

[fervent abyss]

no wait what im confused

what im saying is that the monsterlocation.instance.transform.position gives not the monster location object position but the players position

[polar acorn]

Log MonsterLocation.instance.gameObject.name

See what object it's getting the position from

[fervent abyss]

okay

[sour fulcrum]

(this cannot be true)

[naive pawn]

try t:MonsterLocation in the hierarchy search

[fervent abyss]

huh

[fervent abyss]

jsut 1

[fervent abyss]

        Debug.Log(MonsterLocation.instance.gameObject.transform.position);
        Debug.Log(MonsterLocation.instance.transform.position);```

[sour fulcrum]

MonsterLocation.instance is not going to be the player. it's giving the monster location object position

[polar acorn]

Okay, show the inspector of the Bone object

[fervent abyss]

so how is the monster position = player position at the same time when both are in different places

[polar acorn]

Okay, and does this object have a parent

[fervent abyss]

yes

[polar acorn]

What position is the parent at

[sour fulcrum]

they are not in different places then
