-- By this point, the script (should have) done the following:
-- ► Created an "ESP Folder" directory inside game/CoreGui
-- ► Defined all required functions to create ESP elements
-- ► Have predefined functions: create, getChildren, getDescendants and espObject

-- If one or more of those functions are not working, or the entire script itself is broken, check the Roblox console
-- You can do this by pressing F9 (PC) or by typing /console into the Roblox chat
-- Look for any yellow or red text seemingly related to the script, such as something like "LocalScript:38::Failed to index nil with Name"

-- The getChildren and getDescendants functions are essentially better versions of Instance:GetChildren() and Instance:GetDescendants()
-- The difference being they can be more precise, returning only instances matching the given parameters, rather than every instance in the library

-- An example of getChildren:
-- local allChildren = getChildren(directory, nil, "Folder")

-- Say there were 5 folders inside the directory Instance.
-- As the specificName parameter is nil (does not exist / undefined) and the specificClass is "Folder", the function returns a table of every child Instance that is a folder
-- So the returned table would look something like this:
-- allChildren = {
--    Instance_1,
--    Instance_2,
--    Instance_3,
--    Instance_4,
--    Instance_5
--}

-- To get one of the instances in the table, you simply type the table name, followed by the position of where the desired Instance is in the table
-- So if I wanted Instance_3, I would type allChildren[3]
-- This gets the third Instance in the table
-- Most programming languages start table positions at 0, but Luau starts at 1

-- It's the same with getDescendants, but that get all instances that can be found inside the ancestor, including nested ones (an instance inside another instance)
-- getDescendants can cause performance drops due to it essentially being a deep search, so it advised you do not loop it too much
-- If you need a looping search, I recommend using getChildren, setting the parent parameter to the specific Instance you want to search inside

-- An example of espObject:
-- local object = game.Workspace.Part
-- local espColor = Color3.fromRGB(255, 255, 255)
-- espObject(object, espColor, true, true, "Just a part")

-- This adds a highlight and text to the main directory folder and links them to the object Instance, both of which take on the given color parameter (in this case, white)
-- If no color parameter is provided, the highlight and the text colors will default to green.
-- The given color parameters must be in Color3 format for the function to work
-- To load colors from RGB, Hex or HSV, use Color3.fromRGB(red, green, blue), Color3.fromHex(hexColorCode) or Color3.fromHSV(hue, saturation, volume)
-- Color3.new is basically rgb but on a scale of 0 to 1 for each, 0 being the lowest and 1 being the highest
-- So to get red you'd use Color3.new(1, 0, 0), green you'd use Color3.new(0, 1, 0) and blue you'd use Color3.new(0, 0, 1)
-- To get colors in between, you use decimals
-- Like if I wanted to get dark blue I'd use Color3.new(0, 0, 0.5) or if I wanted pastel pink I'd use Color3.new(1, 0.7, 1)

-- Every line with -- before them are comments, they do not change how the script works (so you do not have to delete these comments if you do not want to)

-- That is all I have to say regarding this script. Have fun making your own ESP scripts using this template.
-- Credit is appreciated, but I'm not going to force it
-- This is just text on a screen, after all
