Have gui frame match a parts size and position on screen for different resolutions

[Thernus]

I’m not sure if there’s a better approach, there’s a good chance that there might be, but this would do something similar to that:

local RunService = game:GetService("RunService")
local Players = game:GetService("Players")

local Rig = workspace.Rig
local Camera = workspace.CurrentCamera

local pivot = Rig:GetPivot()
local position = pivot.Position
local lookVector = pivot.LookVector

local screenGui = Instance.new("ScreenGui")
screenGui.Parent = Players.LocalPlayer.PlayerGui

local frame = Instance.new("Frame")
frame.Parent = screenGui

RunService.RenderStepped:Connect(function()
	local upperTorso = Rig.UpperTorso

	local topLeft = upperTorso.Position - upperTorso.Size/2
	local bottomRight = upperTorso.Position + upperTorso.Size / 2
	
	local leftScreenPoint = Camera:WorldToScreenPoint(topLeft)
	local rightScreenPoint = Camera:WorldToScreenPoint(bottomRight)
	
	frame.Size = UDim2.fromOffset(rightScreenPoint.X - leftScreenPoint.X, rightScreenPoint.Y - leftScreenPoint.Y)
	frame.Position = UDim2.fromOffset(leftScreenPoint.X, leftScreenPoint.Y)
end)

You’ll have to make this code work with your system, and of course disconnect the RenderStepped connection whenever this UI shouldn’t be visible! But this should be able to help get you started, best of luck!

This is about as perfect as it could ever get . Thank you very much!
