Position objects relative to other object

Help and Feedback Scripting Support
#1

So let’s say I have this setup
image
The multiple parts a model. I want each individual to be positioned on top of the blue part, but maintain their relative positions.

local Blue = workspace.Blue
local Model = workspace.Model

for i = 1, 4 do
	local Part = Model[i]
	Part:PivotTo(Blue.CFrame)
	
	task.wait(2)
end


So when the model has been moved over, the model should look the exact same

#2 
local Blue = workspace.Blue
local Model = workspace.Model

local LastPartCFrame, LastPartPos

for i = 1, 4 do
	local Part = Model[i]

If LastPartSize == nil then

Part:PivotTo(Blue.CFrame) + Vector3.new(0,Blue.Position.Y,0)

Else

Part:PivotTo(LastPartCFrame) + Vector3.new(0,LastPartPos/2,0)

end


LastPartSize = Model[i].CFrame
LastPartPos = Model[i].Position.Y

	
	task.wait(2)
end

No clue if this will work so let me know. Just edited to make it work.

Without trying, but just by looking, this needs to work if each colored part were say a seperate model with multiple parts in it. So it can’t just work on a single part basis :grimacing: sorry should have mentioned that in original post

#4

Just make it the primary part. And weld.

Missing a few references

It also doesn’t work anyway :confused:

Not sure if this is what your looking for but i would say save cframe offsets of that red part to each and every part by using .CFrame:Inverse()

-- for each part in that model
-- part is the current part
-- red part is, well, the red part
-- best to save in a table for access
local offset = part.CFrame:Inverse() * redPart.CFrame

Then you can cframe the red part to where you want, and loop through all cframe offsets and set the cframe based off of the cframe of the red parts and the offsets.

-- for each part 
part.CFrame = redPart.CFrame * the_cframe_offset

Or maybe this is just too complicated and your looking for something related to :PivotTo

Seemed to just position them under the red part. There’s no reference to the blue part there either

#9

Did you cframe the red part first? Also I think for the cframe offset code it was supposed to be

local offset = redPart.CFrame:Inverse() * part.CFrame
#10

That still didn’t work unfortunately :confused:

#11 
local Blue = workspace.Blue
local Model = workspace.Model

local LastPartCFrame, LastPartSize = nil

for _, v in Model:GetChildren() do -- Iterate over the model, you can change this to :GetDescendants() if you want.
	if v:IsA("BasePart") then -- Make sure its a part and not a script or anyother object
		
		local Part = v -- Set the part
		
		if LastPartSize ~= nil and LastPartCFrame ~= nil then -- Check if there was a last part
			
			Part.CFrame = LastPartCFrame + Vector3.new(0,LastPartSize ,0)
		else
			
			Part.CFrame = Blue.CFrame + Vector3.new(0,Blue.Size.Y ,0)
		end
		
		LastPartCFrame = Part.CFrame -- Set the last part CFrame to the parts CFrame
		LastPartSize = Part.Size.Y -- Set LastPartSize to parts size

		task.wait(2)
	end
end

I have tried this and it worked. If it doesn’t let me know.
