What does responsiveness mean in align orientation

[mhmdsndb3 (Printer)]

does Responsiveness in align orientation mean how many degrees it can turn per second
if not how would i calculate how many degrees it can turn

[MaxthedaydreamerXMx (maxzieblox)]

It is how fast it will reach the specified orientation.

Good question,

TL;DR it’s just the Kp term in PID responsiveness. The speed varies quite widely depending on the target orientation. However interestingly enough the time taken to reach the goal is similar.

I asked chatgpt to create a test to measure the X axis responsiveness and Y axis is the time taken to reach a goal.

local part = script.Parent -- The part you're testing
local alignOrientation = part:FindFirstChildOfClass("AlignOrientation")
local targetAttachment = alignOrientation.Attachment1

-- Goal orientation (example: rotate 90 degrees on Y axis)
local goalOrientation = CFrame.Angles(0, math.rad(90), 0)

-- Tolerance for "close enough" angle in degrees
local ANGLE_TOLERANCE = 2

-- How long to wait between tests
local WAIT_BETWEEN_TESTS = 2

-- Responsiveness values to test
local responsivenessValues = {1, 5, 10, 20, 40, 80,150,200}

-- Helper to get angle difference in degrees between two orientations
local function getAngleDifference(cf1, cf2)
	local dot = cf1.LookVector:Dot(cf2.LookVector)
	dot = math.clamp(dot, -1, 1)
	return math.deg(math.acos(dot))
end

for _, responsiveness in ipairs(responsivenessValues) do
	-- Reset part orientation
	part.CFrame = CFrame.new(part.Position) -- Reset orientation to identity

	wait(0.1)

	alignOrientation.Responsiveness = responsiveness

	-- Set new goal orientation (relative to attachment)
	targetAttachment.WorldCFrame = part.CFrame * goalOrientation

	local startTime = tick()

	-- Wait until orientation is close enough to target
	repeat
		task.wait()
	until getAngleDifference(part.CFrame, targetAttachment.WorldCFrame) < ANGLE_TOLERANCE

	local timeTaken = tick() - startTime

	print(string.format(" Responsiveness: %d | Time to reach goal: %.3f sec", responsiveness, timeTaken))

	wait(WAIT_BETWEEN_TESTS)
end

Data obtained, noticed the data looked like exponential decay so I plotted it.

The x point at 1 probably does not matter since responsiveness is capped 5-200.

The orange points is when the target is changed to 180 degrees which is much faster in terms of angular velocity but still takes a similar amount of time.

Done with default align orientation settings max torque 10000 and max angular velocity infinite.
