Fixed camera with 45 degree increments

[haughty talon]

I have an idea for a character's camera that makes the character's camera fixed and rotatable between 35 degree increments with slight easing or interpolation or smthn (no snapping) and have NO clue how (the math's too advanced, and don't really know how to mess with the camera)

[pulsar orbit]

1. The math is not that advanced

2. look up a tutorial

3. if all else fails here is mine (top-down camera, the principals remain the same):

local cam = game.Workspace.CurrentCamera
local player = game.Players.LocalPlayer

local TS = game:GetService("TweenService")
local UIS = game:GetService("UserInputService")

local maxZoom = 25
local ScrollMulti = 2

task.wait(.5)

local NewCam = game.Workspace.NewPCamera

local function SetCamera()

cam.CameraType = Enum.CameraType.Scriptable

cam.CFrame = NewCam.CFrame

end

local function Scroll()

UIS.InputChanged:Connect(function(input)
    if input.UserInputType == Enum.UserInputType.MouseWheel then
        local Position = input.Position.Z
        
        if Position > 0 then
            if cam.FieldOfView - (1 * ScrollMulti) >= 70 - maxZoom then
                cam.FieldOfView -= Position * ScrollMulti
            elseif cam.FieldOfView - (1 * ScrollMulti) < 70 - maxZoom then
                cam.FieldOfView = 70 - maxZoom
            end
            
        elseif Position < 0 then
            if cam.FieldOfView + (1 * ScrollMulti) <= 70 + maxZoom then
                cam.FieldOfView -= Position * ScrollMulti
            elseif cam.FieldOfView + (1 * ScrollMulti) > 70 + maxZoom then
                cam.FieldOfView = 70 + maxZoom
            end
        end
    end
end)

end

local function CheckForMovement()

local KeysBeingHeld = {}

local TimeForSmooth = .1

local function SmoothMovement(NextStep)
    local info = TweenInfo.new(
        TimeForSmooth,
        Enum.EasingStyle.Linear,
        Enum.EasingDirection.InOut
    )

    local tween = TS:Create(cam, info, {CFrame = NextStep})

    tween:Play()

    tween.Completed:Wait()
end

local function ContinueMovement()

    while true do

        local NewVelocity = CFrame.new(0,0,0)

        for Key in pairs(KeysBeingHeld) do

if Key == "W" then
NewVelocity = NewVelocity * CFrame.new(0,4,0)
elseif Key == "A" then
NewVelocity = NewVelocity * CFrame.new(-4,0,0)
elseif Key == "S" then
NewVelocity = NewVelocity * CFrame.new(0,-4, 0)
elseif Key == "D" then
NewVelocity = NewVelocity * CFrame.new(4,0, 0)
end
end

        if KeysBeingHeld["LeftShift"] then
            NewVelocity = CFrame.new(NewVelocity.Position * 2)
        end

        SmoothMovement(cam.CFrame * NewVelocity)
    end
end

UIS.InputBegan:Connect(function(input)

    local key = input.KeyCode.Name

    if key == "W" then
        KeysBeingHeld["W"] = true
    elseif key == "A" then
        KeysBeingHeld["A"] = true
    elseif key == "S" then
        KeysBeingHeld["S"] = true
    elseif key == "D" then
        KeysBeingHeld["D"] = true
    elseif key == "LeftShift" then
        KeysBeingHeld["LeftShift"] = true
    end
end)

UIS.InputEnded:Connect(function(input)
    local key = input.KeyCode.Name

    if key == "W" then
        KeysBeingHeld["W"] = nil
    elseif key == "A" then
        KeysBeingHeld["A"] = nil
    elseif key == "S" then
        KeysBeingHeld["S"] = nil
    elseif key == "D" then
        KeysBeingHeld["D"] = nil
    elseif key == "LeftShift" then
        KeysBeingHeld["LeftShift"] = nil
    end
end)

coroutine.wrap(ContinueMovement)()

end

SetCamera()

task.wait()

Scroll()
CheckForMovement()

[pulsar orbit]

put this into StarterCharacterScripts

[haughty talon]

yeah, i usually say that cuz the last time i did that i had to relearn dot products, vectors, and some other.. not happy things

[haughty talon]

" UIS.InputBegan:Connect(function(input)

    local key = input.KeyCode.Name

    if key == "W" then
        KeysBeingHeld["W"] = true
    elseif key == "A" then
        KeysBeingHeld["A"] = true
    elseif key == "S" then
        KeysBeingHeld["S"] = true
    elseif key == "D" then
        KeysBeingHeld["D"] = true
    elseif key == "LeftShift" then
        KeysBeingHeld["LeftShift"] = true
    end" 💔

cant you just use the magnitude

actually no

but js let me do ts

yeah doesnt work

woohoo

time for the debugging process

or js try again to do it

also misses some key points i made

in the question

[pulsar orbit]

well then dont use it

https://tenor.com/view/test-gif-12993999557818669691

[haughty talon]

well then why answer if it doesnt work, and B, misses allat

⛓️‍💥❤️‍🩹

[pulsar orbit]

read it, it's legimately a 1 step set up process

https://tenor.com/view/patrick-stupid-stupid-town-hey-buddy-spongebob-gif-6574682199670721484

[haughty talon]

oh yeah

also the topdown camera u provided that i tested

doesnt work as topdown either 💔

but hey

[pulsar orbit]

yet it does 🥀

[haughty talon]

arguing against stupid people: they never admit defeat

so carry on

[pulsar orbit]

just angle a part named "NewPCamera" 🥀

thats all you have to do ⛓️‍💥

[haughty talon]

1, clearly disproven based on my camera experience

12th grade? im going into NINTH 😭

also

2:

[pulsar orbit]

gng what are you talking about 😭

[haughty talon]

im here BECAUSE i cant find a tutorial

[haughty talon]

the math

guh

[pulsar orbit]

https://tenor.com/view/patrick-stupid-drooling-patrick-star-spongebob-gif-12221001666588210206

no shit

[haughty talon]

🥀

[pulsar orbit]

if you're "so advanced" 🐺 then why couldnt you just read it 🥀

[haughty talon]

i did

[pulsar orbit]

reading -1 moment 📖

[haughty talon]

1: Disproven, the math i need is not my grade level, infact beyond
2: No tutorials i can find, hence im here
3: ur cam script sucks ass

did you read what you wrote??

[pulsar orbit]

1. why does that matter, mathematics and intuitive skills are intertwined and yet so vastly different
2. search harder (it takes everyone atleast 10 minutes to find a good one)
3. because you didn't read it 🌹

https://tenor.com/view/cute-emoji-smiley-thinking-scratching-head-gif-17835192

[haughty talon]

1. no 🥀
2. searched for the past couple o hours on devforums, youtube, etc
3. "(top-down camera, the principals remain the same)", even yet still broken still spits out like 800 errors, etc

so yeah

[pulsar orbit]

"no" 🤡

[pulsar orbit]

https://www.youtube.com/shorts/BNMgjOQ-3FQ

[haughty talon]

" 'no' 🤡 "

did you read the question too

[pulsar orbit]

was this really that difficult?

[haughty talon]

a fixed player camera at an offset with 45 degree rotational increments with interpolation or tweens to prevent immediate snapping

💔

bro is <3rd grade ELA

[pulsar orbit]

I dont think you understand 🥀

[civic elm]

dot product isint rocket science

[pulsar orbit]

you are never going to find a tutorial that specific

[haughty talon]

yeah ik

i still figured it out hopefully 🙏

[haughty talon]

hence

why do you think i am here

[pulsar orbit]

just make it yourself 🙏

[haughty talon]

gang

that's why im here

i do NOT kno how 🙏

read the question

i do NOT know roblox player camera manipulation

[pulsar orbit]

how do you expect to improve if you wont try 🥀

[haughty talon]

i have already spend long enough trying

[haughty talon]

let me finish 💔

[ruby vault]

introduced, yet it's not a hard subject to learn

[pulsar orbit]

⏫

[haughty talon]

ive spent the past 2 days reading docs and trying to make it work

i js restarted cuz it was that bad

[pulsar orbit]

reading < doing

[pulsar orbit]

and (hopefully) you walked out better at what you do?

[haughty talon]

"reading < doing" what the FUCK do you think roblox dev docs are for?

[surreal stream]

https://tenor.com/view/markiplier-fire-fnaf-3-ending-hospital-disaster-gif-1976739374427047349

[pulsar orbit]

development skills of a rock 🙏

[haughty talon]

not really but kinda

i got some cool stuff to work with help

[civic elm]

ur not only meant to be reading the docs lol

[haughty talon]

am i supposed to use the 1000 typewriter monkey strat :broken:

because chat

i read the docs

interperet

and seek help (WHY IM HERE 😭

its literally #1020374354867007528 my FAMILY my BROTHA my FELLA

[haughty talon]

when i need it

and this is one of a few cases my guy

[pulsar orbit]

ask help for simpler, less specific things, not "can you guys do my whole project for me"

[haughty talon]

yeah

but how do i do anything without a start 💔

i dont even kno what i am supposed to do my fella

and i looked at ur script

[pulsar orbit]

are you fucking serious 🙏

[haughty talon]

and honestly

💔 you cant be real

[haughty talon]

yes, im TRYING my guy 😭

but i cant get shit that works but im supposed to make allat work somehow

1000 monkey typewriter methodry

do you realize

its okay to js ask for some help?

[pulsar orbit]

https://tenor.com/view/stan-twt-reaction-meme-funny-begging-crying-gif-11151243012681431164

[haughty talon]

and ur like "but no wahh wahh not whole project"

my FELLA

my BROTHA

my ASSOCIATE

js let me ask for help

and im gonna say smthn so let me type this time

i read the docs, RIGHT? SO I LEARN RIGHT? How ive been taught is by reading, so obviously.

I then interperet as sich, apply the knowledge

and it works

[civic elm]

i still cant tell what youe asking

[haughty talon]

scroll to top

but when I cant figure it out, cant find a proper tutorial, etc,

[civic elm]

yea its too vague

[haughty talon]

I'm stupid for asking?

[civic elm]

lock the camera within a degree range?

[haughty talon]

kindaa

like

you have a locked view looking at char

i can kinda do that??

but

45 degree increments with tweening/interpolation

is giving me a fucking aneurysm

because my guy

i js dont get it

😲

and i need help 🤯

so im going to go back to trying ts 500 different ways and come back in another 2 days because apparently that's the right way to do it?

cyas

[civic elm]

wdym 45 degree increments

[haughty talon]

like

when those games where you press < or > and it aligns the camera

but only that

and no snapping, but like

interpolate or tween it for a smooth transition?

because unless ur that one mariocart, more than 8 directions on a sprite is a bit crazy

[civic elm]

for a SPRITE?

[haughty talon]

for 2d in 3d

[civic elm]

what are u really trying to do

[haughty talon]

yk like baldis basics

where bladi is 2d

its that

but the angle changes

like the back and front of a sprite dependent on if ur looking from the back or the front

and the part i need help with

[civic elm]

but baldi always looks straight at you

[haughty talon]

is the camera that can look around

yeah ik

this is diff

the sprite follows, but the direction they're facing changes(??)

something like that

like yk og mariocart sprites?

let me get u a vid example

[civic elm]

like if youre holding a and w youre at a 45 degree angle

from the camera

[haughty talon]

https://www.youtube.com/watch?v=W4lZQ8nw67w

[haughty talon]

no?

you move

camera stays until moved by the q or e in 45 or -45 repsectively or what ever is left and right im js lost

[civic elm]

what part of this are you trying to replicate

[haughty talon]

yk how

[stable gale]

** You are now Level 8! **

[haughty talon]

the mariokarter

lets say

the direction is always flat to the camera, right?

but the drawing of the sprite rotates

[civic elm]

yea

[haughty talon]

like when u animate a 2d area and on that area a 3d object rotates

the 2d object is the enemy

but

[civic elm]

oh i see what youre tryign to do now

[haughty talon]

the enemy is able to face back and sideways etc

ye?

[civic elm]

yea

[haughty talon]

so yeah

[civic elm]

8 different 2d sprites, pick the one that makes the enemy look like its looking at you

[haughty talon]

yes

well

it would look in one direction but

the sprites would change based off of your direction

like a 2.5d i think it is?

[civic elm]

like the actual world gui is still facing one way but the sprite is changing

[haughty talon]

and those directions are those 45 degree increments

[haughty talon]

the sprite's direction is determined by the player's camera's view vector (is it?) and then calculates some mathy shit ( i cant understand it ) to determine what sprite it should use so the part faces the player but it looks like the sprite is turning

[civic elm]

i think you can pair each sprite(put them all in a table or something) with a direction that its facing(lets call this A for all of them) and then also take the vector pointing from the sprite gui to the player(lets call it B) and then iterate over each A vector and pick the one that has the highest value from the dot product A.B

[civic elm]

well it should be the direction from the sprite to the player

[haughty talon]

its player projecting their view of the sprite

but i see

i think?

but the perspective changing triggers the sprite (based on the 45 degree incremented camera i need) so it rotates away/towards based on the sprite's own view vector (prob js a part it points to ill do or smthn)

[civic elm]

you should just be able to do some cframe math to make the directions paired with the sprites actually point the correct way in the world( enemy.CFrame.Rotation:PointToWorldVector(sprite_dir) .CFrame.Rotation just gets the cframe without position cuz its unnecessary for these unit vecotrs, and then PointToWorldVector pretty much makes it so that for example 1, 0, 0 would be turned into the RightVector for the enemy.CFrame and i hope you can extrapolate to the rest)

[haughty talon]

well

with point to world

would that be the sprite's own direction? (seperate from the part that rotates to the player)

because

let me say my thingy

the view of the sprite changes based on where it goes n stuff

sp

if the player sees it moving

it would see the front then when turning to see it walk away see its back

so idk man im just lost

its very complicated for me which goofy goober didn't understand and just berated me for it

[civic elm]

basically it will rotate the sprite vec that originalyl didint care about where the enemy is facing by how much the enemy is rotate

[haughty talon]

let me draw but i think thats right

and like

8-directionals

so ngl

its actually like how doom did it

i should have said THAT

HWEQETHETHBNA

but not really how they did it

the way im doing it is a far ways different

[civic elm]

npc is red, sprite direction chosen is blue, purple is the direction vector enemy->playre, player is green dot, you can see blue direction is the most aligned(dot product shows how aligned 2 vectors are) and why its chosen

[haughty talon]

yeah

like this, small part is the enemie's sprite's look direction

but

the big flat panel would turn to you

and show the apropriate sprite based on ur perspective

[civic elm]

yea

[haughty talon]

so yeah

so i needa make the camera, say when it updates

and since its an interpolation/tween

update the view 1/2 way thru

so when you turn

the npc looks like it's turning too

based on ur perspective

let me draw

[civic elm]

nothing should happen to the sprite when you turn your camera

[haughty talon]

yeah

because its kinda like a haptic snap on a nob

[civic elm]

the camera snaps onto the npc?

[haughty talon]

if half way below 45 and half way above -45

the view remains the same

yk

so when you turn ur camera (above the half-way-45)

it turns with you kinda???

[civic elm]

so if the player is roughly looking at the npc nothing happens, but if you turn too much, theres a lerp back to the middle

oh shoot i gtg

[haughty talon]

there's a lerp that says "oh shoot i need to rotate here so persppective" idk

ill figure it out i hope

I'm back sorry for the afk, had to do stuff around the house

[raw oyster]

HI

[haughty talon]

ive been dead 😭

lots of stuff goin on

[haughty talon]

is this officially dead lmao'

back to the grind
