Limit CFrame Rotation? [Not Answered]
So this script makes a Part follow you're mouse. Thing is, I dont want the part to be turning to the mouse if it's pointing 180 degrees of that part. I would like to limit it like, 30 degrees to the left and right (Doesnt need to be exactly 30, just some number that limits the parts CFrame Rotation.)
local Player = Game.Players.LocalPlayer local Mouse = Player:GetMouse() while true do local person = Player.Character if person ~= nil then local neck = Player.Character.ATST.Head.Neck local looking = CFrame.new ( neck.Position, Mouse.Hit.p ) neck.Neck.C0 = neck.CFrame:toObjectSpace(looking) end wait() end

Here's a simple function I wrote that limits a vector v to be within a certain angle (in radians) to vector d.
function coneLimit(v,d, angle)
v , d = v.unit, d.unit;
local dot = d:Dot(v)
local toward = dot * d;
local side = v - toward;
local outtoward = math.max( math.cos( angle ) , dot) * d;
local om = outtoward.magnitude;
local sm = side.magnitude;
-- (Q * sm)^2 + om ^ 2 = 1
-- sqrt(1 - om^2) / sm = Q
local Q = math.sqrt(1 - om^2) / sm;
local outside = side * Q;
return side * Q + outtoward;
end
Essentially, this constructs a triangle using two components: the component forward (in the direction of d) and the component to the side (side).
It restricts the forward to have to be forward by at least a certain amount (outtoward) and then sums that with a scaled side (by Q) to use the right proportion of each to make a unit vector.
A hypothetical use would be the following, to restrict a headlookvector to be within 30 degrees of a torsolookvector.
headlookvector = coneLimit( headlookvector, torsolookvector, math.rad(30) )
