Trying to make constant speed rotating tank turret

This only happens if you call lerp on a lerp product. If you lerp on a starting point then you should get a constant speed.

function lerp(a, b, c)
	return a + (b - a) * c
end

local Alpha = 0
local Start = CFrame.new()
local Goal = CFrame.Angles(math.rad(math.random(0, 360)), math.rad(math.random(0, 360)), math.rad(math.random(0, 360)))
local Current = Start

game:GetService("RunService").heartbeat:Connect(function(DeltaTime)
	Alpha += DeltaTime
	Current = lerp(Start, Goal, Alpha)
end)

This will move the value of Current to Goal at a consistent speed.

How would I change Goal to a Vector 3?

Maybe try changing the Goal and Start variable to a vector3.

How would I test it to see if it works?
