What ways could I achieve this

How would find the distance between a parts top and bottom.
Unlike finding the distance between two several parts. I’m only trying to find the distance between a parts top and bottom. I haven’t tried any solutions yet because I don’t think there currently is a method of finding the distance between a part’s top and bottom.

What if you made two points and just added/subtracted the part’s size to it?

local top = part.Position + Vector3.new(0, part.Size.Y/2, 0)
local bottom = part.Position - Vector3.new(0, part.Size.Y/2, 0)

local dist = (top - bottom).Magnitude

Just an idea, but this might work:

math.abs(part1.Position.Y - part2.Position.Y)

Please read my first post carefully. To keep it simple I’m only using one part.

when you say the distance from the top to the bottom, do you just mean the size of the part’s Y?

Could you explain this in a more informative way?

#7

if the part’s orientation is 0,0,0 then the part.Size.Y is the distance from the top of it to the bottom of it

This works but only when the part is completely not rotated

You could try this script that gets the cframe positions of the top and bottom faces using the part’s size’s Y component

function FindDistBetweenTopAndBottom(Target: BasePart)
	local Top = Target.CFrame:ToWorldSpace(CFrame.new(0,Target.Size.Y/2,0)).Position
	local Bottom = Target.CFrame:ToWorldSpace(CFrame.new(0,-Target.Size.Y/2,0)).Position
	
	return (Top - Bottom).Magnitude
end

You can also use this function to get distance between left/right front/back faces by using x or z components

This is equivalent to Part.Size.Y. You just added half of Size.Y to itself Size.Y/2 + Size.Y/2 which is equal to Size.Y.

#11

There may be a better way to do this, but this is my solution. This function returns a Vector3 size. In your case, you would index the Y value to only get the height.

This is for only one part.

local function GetBoxSize(Part: BasePart): Vector3
	local model = Instance.new("Model")
	local clone = Instance.new("Part",model)
	clone.Size = Part.Size
	clone.CFrame = Part.CFrame
	model.WorldPivot = CFrame.identity
	return select(2,model:GetBoundingBox())
end

This is for multiple parts

local function GetBoxSize(Parts: {BasePart}): Vector3
	local model = Instance.new("Model")
	for _, v in ipairs(Parts) do
		local clone = Instance.new("Part",model)
		clone.Size = v.Size
		clone.CFrame = v.CFrame
	end
	model.WorldPivot = CFrame.identity
	return select(2,model:GetBoundingBox())
end

This reply is the equivalent of finding the parts size, which could be simply be done by doing:

local size =  p.Size
#13

All this is currently doing is finding the the parts y axis.

#14

S = parts.Size.Y/2 is distance from center so pretty much you do (top = part.Position.Y +S) (bottom = part.Position.Y -S)

#15

I don’t think you know how this works.

  1. First of all, it takes all parts into a model
  2. Then it sets the model’s world pivot to CFrame.identity (Zero rotation, and Zero position)
  3. Then it takes its Bounding Box (CFrame Pos, Vector3 Size)

Clearly you haven’t tested my script, because I did, and I know that it works. It takes the size of a part in global rotation.

If you don’t know about pivot, you can search about it. If you don’t know about CFrame, you can search about it. If you don’t know about the Bounding Box, it is just the size of a model.

And also, about the solution and the problem, the solution was taking the position of the parts top and bottom. But in your post you said “distance between top and bottom” which is equal to Part.Size.Y.

#16

You’re coming off as quite rude. The only thing is script does is fine the parts y. And I have tested that piece of waste you call code. I usually don’t get frustrated about some dude criticizing my profession, and skills. The only reason I selected him as the solution was because every single post has been the same, including yours, the only difference was that you made it more complicated than it had to be. I’m sincerely sorry if this comes off as rude. :crying_cat_face: .

#17

I’m sorry if I was rude aswell. I understand what you are saying. Its just that I hate when people judge code without testing it first. I thought you did not test it so I got irritated, thus what I said was also affected.

I tested this, and I got close results. If it did not work for you, I will just post screenshots of me doing it and my code working.

You wanted a different solution anyways (and I misunderstood your problem) so let’s not argue about my code not working.

#18

I never so your code didn’t work. And I’m personally sorry, if this offended you in way.
