Motor6D Rotation Values Not Setting Properly

[ne3ulimity]

I’m trying to make it so players can hold items in my game, so I decided to use Motor6D’s as the attachment method. I used the explorer to edit the values so that the character holds the item “correctly,” and then I apply them in a script when the player picks up an item.

However, the angles 20, -90, 50 turn into 0, -90, 30 once i set them in the script.

Angles set using explorer:

Angles set with the script

Config table:

Offsets = {
			R6 = {
				C0 = CFrame.new(-0.4, -1.4, -0.4) * CFrame.Angles(math.rad(20), math.rad(-90), math.rad(50)),
				C1 = CFrame.new(),
			},
			R15 = {
				C0 = CFrame.new(-0.4, -0.4, -0.4) * CFrame.Angles(math.rad(20), math.rad(-90), math.rad(50)),
				C1 = CFrame.new(),
			},
		},

The script:

local offset = definition.Offsets[rigKey]
local c0, c1 = offset.C0 or CFrame.new(), offset.C1 or CFrame.new()
local motor6D = Instance.new("Motor6D")
motor6D.Part0 = attachPart
motor6D.Part1 = model.PrimaryPart
motor6D.C0    = c0
motor6D.C1    = c1
motor6D.Parent= attachPart

Thanks for any help because I’m really confused.

• For empty CFrame please use CFrame.identity
  And dont call constructor each time.
• Consider looking at CFrame overloads and i think

CFrame.new(Vector3.new(),Vector3.new())

Is the one you are looking for.

• Consider doing better formatting:

--!strict
type Offsets = {
	[Enum.HumanoidRigType]:{
	C0:CFrame;
	C1:CFrame
}
}
local Offsets:Offsets = {
	[Enum.HumanoidRigType.R15]={
		C0=CFrame.identity;--Your cframe thingy here
		C1=CFrame.identity;--Your cframe thingy here
	};
	[Enum.HumanoidRigType.R6]={
		C0=CFrame.identity;--Your cframe thingy here
		C1=CFrame.identity;--Your cframe thingy here
	}
}

Thanks for the suggestions on the formatting!
I tried using CFrame.new(Vector3.new(-0.4, -1.4, -0.4), Vector3.new(math.rad(20), math.rad(-90), math.rad(50))) instead of CFrame.new(-0.4, -1.4, -0.4) * CFrame.Angles(math.rad(20), math.rad(-90), math.rad(50)), but unfortunately now my angles appear as -6.6, -150, 0.

what is the model.primarypart and attacthPart? if model.primary part is the character primarypart then you may want to change it to humanoidrootpart

[ne3ulimity]

The model’s primary part is Handle (the mesh used for the model).

[b6d7a]

okay then the attachpart is the rootpart?

[ne3ulimity]

It attaches itself to the Right Arm.

Motor6D.Part0 = character["Right Arm"]
Motor6D.Part1 = Handle

[b6d7a]

then just try adjusting angles

[ne3ulimity]

i will do that as a last resort, but id rather not just guess random angles until it looks right in game

[b6d7a]

looks like you might need to go ahead with it, since the way youre getting the angle from the explorer isnt giving accurate values when used with the motor.

I ended up discovering the issue. CFrames are rotated in YXZ order. So instead of:

C0 = CFrame.new(x_pos, y_pos, z_pos) * CFrame.Angles(math.rad(x_rot) math.rad(y_rot), math.rad(z_rot))

it would actually be:

C0 = CFrame.new(x_pos, y_pos, z_pos) * CFrame.Angles(0, math.rad(y_rot), 0) * CFrame.Angles(math.rad(x_rot), 0, 0) * CFrame.Angles(0, 0, math.rad(z_rot)),
