Issues with Converting CFrame To Attachment's Object Space

[Pan_Shyrikys (Mad)]

My goal is to convert the Y cframe orientation in world space to an attachment’s object space so that no matter where the attachment’s parent is looking, it will always point towards required direction.

local x,y,z = CFrame.Angles(0,YOrientation,0):ToObjectSpace(rope.Hook.Attachment.CFrame):ToOrientation()

rope.Hook.Attachment.CFrame = CFrame.Angles(0,y,0)

Where YOrientation is camera’s cframe Y orientation in radians converted via the same method

local x,y,z = game.Workspace.CurrentCamera.CFrame:ToOrientation()

The issue is that it doesn’t seem to point into the direction it’s supposed to.

Thank you for your attention.

Try this:

attachmentWorldCFrame = attachment.Parent.CFrame * attachment.CFrame
--To solve for attachment.CFrame, apply parent inverse left sides of the equation
attachment.Parent.CFrame:Inverse() * attachmentWorldCFrame =  attachment.CFrame
--rearrange
attachment.CFrame = attachment.Parent.CFrame:Inverse() * attachmentWorldCFrame 

--Apply desired World CFrame
local x,y,z = game.Workspace.CurrentCamera.CFrame:ToOrientation()
local rotationCF = attachment.Parent.CFrame:Inverse() * CFrame.fromOrientation(0,y,0)
attachment.CFrame = rotationCF.Rotation + attachment.CFrame.Position --Maintain original attachment position, use new rotation CFrame

There is also the attachment.WorldCFrame property which could also be used.
