Retreiving Sides Position

Hello Devs!

I’ve been having a tiny problem with getting the Left and Right Positions of a Part, to place another Part. I’ve already got the Top and Bottom

-- Top
AddedPart.CFrame = Target.CFrame + Vector3.new(0, Target.Size.Y/2 + AddedPart.Size.Y/2, 0)

-- Bottom
AddedPart.CFrame = Target.CFrame + Vector3.new(0, -Target.Size.Y/2 - AddedPart.Size.Y/2, 0)

I’ve tried to do the Right side but it doesn’t seem to move at all.

-- Right
AddedPart.CFrame = Target.CFrame + Vector3.new(-Target.Size.X/2 + AddedPart.Size.X/2, 0, 0)

Sorry if this is a easy question, practicing object oriented scripting!

CFrame multiplication is basically just applying relative positions

part.CFrame * CFrame.new(leftRight,0,0) gets the left and right offsets relative to the part
part.CFrame * CFrame.new(0,upDown,0) gets the up and down offsets relative to the part
part.CFrame * CFrame.new(0,0,frontBack) gets the front and back offsets relative to the part

These can all be combined to do some pretty useful things
So basically all you need to do is do * CFrame.new( instead of + Vector3.new(

Oh okay, thank you for the info!

I tried doing it with CFrame multiplication, It worked with top and bottom again, but not the other sides like Right

-- CFrame Multiplication | Right Side
AddedPart.CFrame = AddedPart.CFrame * CFrame.new(Target.Size.X/2 + AddedPart.Size.X/2,0,0)

Unless I am doing it wrong, I probably am :sweat:

I think its just that you accidentally put AddedPart on the second part instead of Target
Like:

AddedPart.CFrame = Target.CFrame * CFrame.new(Target.Size.X/2 + AddedPart.Size.X/2,0,0)

Hmm, I have no Idea of how I missed that, but It still doesn’t work, It just stays at original Parts CFrame.

#6

The added part doesnt move at all? Or does the added part go to the target but not the right position

#7

It goes to the target but not the right position.

#8

Does it go to the front? Left? etc
If so it would just be as simple as changing around the values a bit until it works

#9

It doesn’t go either, It goes to the original target’s CFrame

#10

Have you tried using the Z size instead or made other small changes which might affect it?
You could even try putting a set value in the cframe to see if its properly responding to a value
Eg:

AddedPart.CFrame = Target.CFrame * CFrame.new(10,0,0)

I just tested it and it worked! but It doesn’t work on that line

	if selection == Target then
		if side == "Top" then
			AddedPart.CFrame = Target.CFrame * CFrame.new(0, Target.Size.Y/2 + AddedPart.Size.Y/2, 0)
		elseif side == "Bottom" then			
			AddedPart.CFrame = Target.CFrame * CFrame.new(0, -Target.Size.Y/2 - AddedPart.Size.Y/2, 0)
		elseif side == "Right" then -- Doesn't work here
			AddedPart.CFrame = Target.CFrame * CFrame.new(Target.Size.X/2 + AddedPart.Size.X/2,0,0)	 -- Works Perfectly
		end
	end

Wow, not sure why but the problem wasn’t the placement but it was the if statement. Didn’t know it couldn’t hold more than 3 elseif. Thank you for your help!
