Rotation around pivot point

[DesertFoxHU]

Helo!

I want to make a lever on top of a wagon/train like this and move it around it’s pivot point:

I’ve tried so many things to try to rotate around it’s own pivot point or around a pivot part.
But I just became more confused about it.

So I will include a model so anybody can try it or check it:
train.rbxm (10.3 KB)

There is a part called “Power” which is connected to the wagon by weld, on top of that is a pivot part connected by motor6d to the pole part (I’ve tried without physical parts too) and the pivot part connected by weld to the lever.

I’ve already tried make it the whole thing a model, setting a primary cframe, lots of different formula and calculate into Orientation.

If I am not mistaken the official doc says something about you can’t move parts by CFrame when they are connected or atleast if you want to move a part locally (without affecting the other connected parts). So I converted everything to Orientation:

local rx, ry, rz = newFrame:ToOrientation();
local dx, dy, dz = math.deg(rx), math.deg(ry), math.deg(rz);
	
lever.Orientation = Vector3.new(dx, dy, dz);

However the best result was only rotation in a very weird angle (spin around on local X axis or around it’s center).

So to summerize: I want to achieve the level part to rotate around it’s pivot point in right or left direction.

Thanks for any help!

Try This:

local pivot = Vector3.new(0, 0, 0)
local part = workspace.Part

local newpivot = CFrame.new(pivot) -- Create decoy pivot that will "rotate"
local offset = newpivot:toObjectSpace(part.CFrame) -- Get the offset from the part to the pivot
while wait() do
newpivot = newpivot * CFrame.Angles(0, math.rad(1), 0) -- Rotate the pivot
part.CFrame = newpivot * offset -- Re-offset the part from the new rotation
end

I’ve seen this answer in some other topics and I don’t in the past I’ve tried this too.

The wagon just starts flying randomly, it looks very glitchy and other parts move with the wagon.

With this modification, the lever rotates locally but around it’s own center not around the pivot point.

local pivot = Vector3.new(0, 0, 0)
local part = script.Parent

local newpivot = CFrame.new(pivot) -- Create decoy pivot that will "rotate"
local offset = newpivot:toObjectSpace(part.CFrame) -- Get the offset from the part to the pivot
while wait() do
	newpivot = newpivot * CFrame.Angles(0, math.rad(1), 0) -- Rotate the pivot
	local newFrame = newpivot * offset -- Re-offset the part from the new rotation
	
	local rx, ry, rz = newFrame:ToOrientation();
	local dx, dy, dz = math.deg(rx), math.deg(ry), math.deg(rz);

	part.Orientation = Vector3.new(dx, dy, dz);
end

I am starting to think the problem here is the conversion to Orientation not the CFrames

instead of using math.rad try using math.deg

Made your train lever connected via motor6d as oppose to a weld now you can rotate it nicely.
