How to use Cos and Sin

Version française: https://devforum.roblox.com/t/comment-utiliser-cos-et-sin/1660043 This tutorial will explain you how to use cos and sin inside of a Roblox experience. In Roblox, you can access cos and sin with the math.cos() and math.sin() functions respectively. What are cos and sin Basically, cos and sin are mathematical functions, they ...

i know the basics of trigo..

wooden kettle Oct 18, 2022, 1:17 AM

#

for i = 1, 7 do
    local formula = i * ((math.pi*2)/7)
    local position = Vector3.new(math.cos(formula) * 5, 5, math.sin(formula) * 5)
    
    local part = Instance.new("Part")
    part.Anchored = true
    part.Size = Vector3.new(1, 1, 1)
    part.Position = position
    part.Parent = workspace
end

#

^ creates a circle with parts

#

#

roughly the same idea

heady summit Oct 18, 2022, 1:18 AM

#

mhm. So in this case,

#

I'd prob need to do:

#

for i = 1,#Players:GetPlayers(), right?

wooden kettle Oct 18, 2022, 1:18 AM

#

yes

heady summit Oct 18, 2022, 1:18 AM

#

[that command would only run when more than 1 person is in server]

wooden kettle Oct 18, 2022, 1:19 AM

#

just put :GetPlayers() in a variable

#

your going to use it multiple times anyways

wooden kettle Oct 18, 2022, 1:19 AM

#

wooden kettle ```lua for i = 1, 7 do local formula = i * ((math.pi*2)/7) local positio...

see where it says /7

#

in local formula

Mhm

wooden kettle Oct 18, 2022, 1:19 AM

#

you basicly plugin your playercount there

#

because the for loop is 7 cubes

heady summit Oct 18, 2022, 1:20 AM

#

That's the 'indicator' for how many bricks to create?

wooden kettle Oct 18, 2022, 1:20 AM

#

yes

heady summit Oct 18, 2022, 1:20 AM

#

so the 7 there in the for i =1,7 do has to be the same number as that /7?

wooden kettle Oct 18, 2022, 1:20 AM

#

yes

#

And afaik

#

If its just one

#

then it will work correctly

heady summit Oct 18, 2022, 1:21 AM

#

very good.

wooden kettle Oct 18, 2022, 1:21 AM

#

trig ~= triangles

#

trig == circles

heady summit Oct 18, 2022, 1:21 AM

#

correcto.

If the above needs any clarification:

#

for i = 1,7 do
local formula = math.pi*2/7*i
local x = math.cos(formula) * 10 -- radius
local z = math.sin(formula) * 10 -- radius again
local part = Instance.new("Part")
    part.Anchored = true
    part.Size = Vector3.new(1, 1, 1)
    part.Position = Vector3.new(x,5,z)
    part.Parent = workspace
task.wait()
end

#

someone "simplified" it

#

its simply the same

heady summit Oct 18, 2022, 1:23 AM

#

true.

#

local Players = game:GetService("Players")
local exampleObject = game.Workspace.exampleObject 

local function tpPlayers()
    local TotalPlayers = #Players:GetPlayers()
    for i = 1, TotalPlayers do
        local formula = i * ((math.pi*2)/TotalPlayers)
        local position = Vector3.new(math.cos(formula) * 5, 5, math.sin(formula) * 5)

        local part = Instance.new("Part")
        part.Anchored = true
        part.Size = Vector3.new(1, 1, 1)
        part.Position = position
        part.Parent = workspace    
    end
end

Players.PlayerAdded:Connect(function(Player)
    Player.Chatted:Connect(function(Message)
        local messages = Message:Split(" ")
        if messages[1] == "!Circle" then
            if messages[2]:lower() == "all" then
                for _,player in pairs(Players:GetPlayers()) do
                    
                end
            end
        end
    end)
end)

#

okay

#

i have this now

#

so what I need to do is

wooden kettle Oct 18, 2022, 1:24 AM

#

that *5 in the formula

#

is how spaced out it is

#

you could add that as a parameter to your admin system

heady summit Oct 18, 2022, 1:24 AM

local Players = game:GetService("Players")
local exampleObject = game.Workspace.exampleObject 

local function tpPlayers(player)
    local TotalPlayers = #Players:GetPlayers()
    for i = 1, TotalPlayers do
        local formula = i * ((math.pi*2)/TotalPlayers)
        local position = Vector3.new(math.cos(formula) * 5, 5, math.sin(formula) * 5)

        local part = Instance.new("Part")
        part.Anchored = true
        part.Size = Vector3.new(1, 1, 1)
        part.Position = position
        part.Parent = workspace    
        player.Character:PivotTo(part)
        part:Destroy()
    end
end

Players.PlayerAdded:Connect(function(Player)
    Player.Chatted:Connect(function(Message)
        local messages = Message:Split(" ")
        if messages[1] == "!Circle" then
            if messages[2]:lower() == "all" then
                for _,player in pairs(Players:GetPlayers()) do
                    tpPlayers(player)
                end
            end
        end
    end)
end)

#

should this work?

wooden kettle Oct 18, 2022, 1:24 AM

#

well right now its just going to make parts

#

but afaik yes

heady summit Oct 18, 2022, 1:25 AM

#

tho i dont really need the parts

#

is it possible to still spawn the players in a circle without the need of creating the parts

wooden kettle Oct 18, 2022, 1:25 AM

#

the pivotto thing seems a little off

#

all you need is two vector3s and your good

#

Player.Character.PrimaryPart.CFrame = CFrame.new( pos1, pos2 )

#

and it should point your character in the correct direction

#

make sure you only supply two vector3 values

heady summit Oct 18, 2022, 1:26 AM

local function tpPlayers(player)
    local TotalPlayers = #Players:GetPlayers()
    for i = 1, TotalPlayers do
        local formula = i * ((math.pi*2)/TotalPlayers)
        local position = Vector3.new(math.cos(formula) * 5, 5, math.sin(formula) * 5)
        player.Character.PrimaryPart.Position = position
    end

        local charpos = player.Character.PrimaryPart.Position
        player.Character.PrimaryPart.CFrame = CFrame.new( charpos, position )
    end
end

heady summit Oct 18, 2022, 1:28 AM

#

same thing right?

wooden kettle Oct 18, 2022, 1:28 AM

#

no

#

you need to use cframe for this

heady summit Oct 18, 2022, 1:28 AM

#

why does it matter

wooden kettle Oct 18, 2022, 1:28 AM

#

Do you want the players to face the spawner?

heady summit Oct 18, 2022, 1:29 AM

#

mhm

wooden kettle Oct 18, 2022, 1:29 AM

#

wooden kettle ```lua local function tpPlayers(player) local TotalPlayers = #Players:GetPla...

The above code will do that

#

simply just setting the position alone will not

heady summit Oct 18, 2022, 1:29 AM

#

hm

#

but how do I face them

#

to look at a given object

#

#

should I use lookAt?

wooden kettle Oct 18, 2022, 1:31 AM

#

thats what its doing

#

by providing two vector3 values

This is using the same method I just showed you

heady summit Oct 18, 2022, 1:32 AM

#

well

#

when i tested it

#

they didnt face to that part

#

local Players = game:GetService("Players")
local exampleObject = game.Workspace.exampleObject 

local function tpPlayers(player)
    local TotalPlayers = #Players:GetPlayers()
    for i = 1, TotalPlayers do
        local formula = i * ((math.pi*2)/TotalPlayers)
        local position = Vector3.new(math.cos(formula) * 5, 5, math.sin(formula) * 5)
        player.Character.PrimaryPart.CFrame = CFrame.new(exampleObject.Position,position)
    end
end

#

so i changed

wooden kettle Oct 18, 2022, 1:33 AM

#

does that work?

heady summit Oct 18, 2022, 1:33 AM

#

not at all, ill now show a video.

It seems to work but has few issues.

#

local function tpPlayers(player)
    local TotalPlayers = #Players:GetPlayers()
    for INDEX,PLAYER in pairs(Players:GetPlayers()) do
        local formula = INDEX * ((math.pi*2)/TotalPlayers)
        local position = Vector3.new(math.cos(formula) * 5, 5, math.sin(formula) * 5)
        PLAYER.Character.PrimaryPart.CFrame = CFrame.new(exampleObject.Position,position)
    end
end

#

maybe this can help

heady summit Oct 18, 2022, 11:31 PM

#

to spawn players

#

in a circle way

#

facing a part

#

the only issue i have now

#

is that it spawns them in circle but not surrounding the part
