Where/how should I use ToWorldSpace and ToObjectSpace?

[alexfinger21 (pro)]

The question says it all, so if you know the answer to this, please help.

ToObjectSpace and to world space is commonly with Motor6Ds to manipulate the C0 and C1 of the joints as they are relative the the part0 object space and part 1 object space respectively.

Head face mouse script causing head to dissapear

local relativizeToWorld = neckJoint.Part0.CFrame:Inverse() neckJoint.C0 = relativizeToWorld*CFrame.lookAt(head.Position, mouse.Hit.Position) Edit: NVM, here is another technique you can use to maintain C0 Position. local goalCFrame = CFrame.lookAt(head.Position, mouse.Hit.Position) local relativizeToWorldCFrame = neckJoint.Part0.CFrame:ToObjectSpace(goalCFrame) local goalRotationOnly = relativizeToWorldCFrame-relativizeToWorldCFrame.Position neckJoint.C0 = CFrame.new(neckJoint.C0.Position)*goa…

Same goes for the new bone instances with skinned meshes

How do I translate a set of cframe values in world-space and convert them into the object-space for a Bone Chain?

Before we even get to the CFraming, I’m going to need sauce on this: Have you done any benchmarking? With the preferable method I learnt now with os.clock()

Sample benchmarking code

local startTime = os.clock() for i=1,10000 do --Put your test code here end local deltaTime = os.clock() - startTime print("Elapsed time method 1: " .. deltaTime)

Otherwise, yeah you got the formula correctly, but you haven’t applied ToObjectSpace correctly since you will need to inverse the parent CFra…

Here is an example with point to object space used for a Motor6D turret

How do I apply PID to CFrame lerping?

Nice! Here’s what I’ve come up with, it only rotates on the yaw axis, I was thinking it’d be interesting to have yaw and pitch be different “hinges” / Motor6Ds: [pd]

TurretController

local RunS = game:GetService("RunService") local PIDController = require(game.ServerStorage.PIDController) PIDController.update_time_on(RunS.Heartbeat) local turret = script.Parent local turretBase = turret.Base local yawBase = turret.YawAssembly.YawBase local yawMotor = turret.Base.YawMotor6D …

And also welds can also have C0 and C1 properties and hence be CFrame animated but usually we expect welds to not move like Motor6Ds so we use Motor6Ds instead of welds.

There are probably other cases but personally I mostly work with Motor6Ds CFrame animations where ToObjectSpace is used a lot so that should show the possibilities of using the CFrame functions.
