How to determine if an object is rotated to another object

[Heural_Network (SUS)]

It so happened that I need to determine whether the player is turned to another player. I have read a lot about CFrame but didn’t understand how to do it. I will be glad if you tell me how to do it.
I want to note that I don’t need to determine whether the player is turned to another without rejections, but it is necessary that there be an error in which it would be determined whether the player is looking at the player.

Detecting a parts rotation

Hi, I’m trying to figure out how to detect the cars orientation/rotation so I can place items in the correct locations. Here is what I’m talking about: [image] [image] Would anyone know where I can look into or how to code this?

How to check if an object is within an angle of the front of a player’s characters?

[image] Is there any way to check if the object is in the striped area which is within an angle of the front of a player’s character (not camera)? A simpler concept would be whether there is a way to determine whether an object is in front or behind of the player?

How would I check if a player is facing a part

How would I check if the player is facing the front or back of a part?

	local p1 = game.Workspace.Part
	local p2 = game.Workspace.Part2

	local theoreticaldirection = (p2.Position-p1.Position).Unit
local realdirection = p1.CFrame.LookVector
local dotproduct = theoreticaldirection:Dot(realdirection)
if dotproduct > 0.95 and dotproduct <1.05 then -- you can increase the error size here.
	print("yes")
end

I made a working code:

-- Below there should be paths on the part of the players from which we will determine their rotation
local p1 = game.Workspace.Part -- Which player we will determine if he is looking at 2 player
local p2 = game.Workspace.Part2 -- Player2

local Facing = p1.CFrame.LookVector
local Vector = (p2.Position - p1.Position).unit

local Angle = math.acos(Facing:Dot(Vector))
local C = math.deg(Angle) -- Converting radians to degrees

if C > 100 and C < 180 then -- See photo
	print("Yes")
end

Also a picture with degrees:

Part rotation: 0, 0, 0
