I got some trouble here help pleas ? help this poor bacon guy finish his task ;(

local player = game.Players.LocalPlayer
local Character = player.Character or player.CharacterAdded:Wait()
local Mouse = player:GetMouse()

local BodyAngularVelocity = script.Parent:WaitForChild("BodyAngularVelocity")

local Patterns = { 
	Pattern1 = {
		Vector3.new(0, 0, 0),
		Vector3.new(0, 0, 0),
		0.0
	},
	
	Pattern2 = {
		Vector3.new(0, -10, 0),
		Vector3.new(0, 50, 0),
		0.25
	},
	
	Pattern3 = {
		Vector3.new(0, 25, 0),
		Vector3.new(0, 50, 0),
		0.5
	}
}

Mouse.Button1Down:Connect(function()
	for Key, Variables in pairs (Patterns) do
		print(Key) -- here is the print thing
		BodyAngularVelocity.AngularVelocity = Variables[1]
		BodyAngularVelocity.MaxTorque = Variables[2]
		
		wait(Variables[3])
	end
end)

However, it keeps printing

Pattern2
Pattern3
Pattern1

Why!?!? WHY ROBLOX

help me else ill have a mental breakdown

Dictionaries don't behave like Arrays. In it's largest difference, it doesn't have any uniform containment, as it's indices are completely random, there is no way for it to have any form of natural order. This is why when iterating over the key-value pairs, they are arbitrarily outputted.

To resolve this problem, you can form an array containing the desired references in their proper order:

local scatteredDictionary = {
    letter2 = {"a"}; letter3 = {"b"};
    letter4 = {"c"}; letter1 = {"d"}
}

local correctOrder = {"letter2", "letter3", "letter4", "letter1"}

local allAttributes = {}
for _,index in pairs(correctOrder) do
        table.insert(allAttributes, scatteredDictionary[index]))
end

print(table.concat(allAttributes, ", "))
--// -> "a, b, c, d"
