Can anyone help me tackle an 8 direction Animation Script?

So I'm working on a Animate script that will hopefully have 8 different animations for all 8 directions. Aka up, down, left, right, up right, up left, down right, and down left. Pretty simple on paper but I'm struggling with understanding concepts like :AdjustWeight and other animation gimmicks. Was wondering if someone could help me figure out a way to make the script without have a mish-mash of conditions and exceptions.

What I have right now is this which I borrowed from another post about a similar topic. But sadly it only handles 4 directions(up,down,left,right) and I'm trying to see if I can make it handle 8 instead

local character = script.Parent
local humanoid = character:WaitForChild("Humanoid")
local agility = character:WaitForChild("Agility")
local UIS = game:GetService("UserInputService")
script:WaitForChild("leftwalk"):WaitForChild("Animation")
local currently_playing_anim = {}
local anim = {
	["frontrun"]=humanoid:LoadAnimation(script.Movement.run.Animation);
	["frontwalk"]=humanoid:LoadAnimation(script.Movement.walkA0.Animation);
	["frontrightwalk"]=humanoid:LoadAnimation(script.Movement.walkA2.Animation);
	["frontleftwalk"]=humanoid:LoadAnimation(script.Movement.walkA1.Animation);
	["rightwalk"]=humanoid:LoadAnimation(script.Movement.walkA4.Animation);
	["leftwalk"]=humanoid:LoadAnimation(script.Movement.walkA3.Animation);
	["backrightwalk"]=humanoid:LoadAnimation(script.Movement.walkA6.Animation);
	["backleftwalk"]=humanoid:LoadAnimation(script.Movement.walkA5.Animation);
	["backwalk"]=humanoid:LoadAnimation(script.Movement.walkA7.Animation)
	}
local X,Z = 0,0
for i,v in pairs(anim) do
	v:Play()
	v.Looped = true
end
local function setallweight(num)
	for i,v in pairs(anim) do
		v:AdjustWeight(num)
	end
end

humanoid:GetPropertyChangedSignal("WalkSpeed"):Connect(function()
	anim["backwalk"]:AdjustSpeed(humanoid.WalkSpeed/10)
	anim["frontwalk"]:AdjustSpeed(humanoid.WalkSpeed/10)
	anim["frontrun"]:AdjustSpeed(humanoid.WalkSpeed/25)
end)

			anim["frontrun"]:AdjustWeight((agility.Value/10)-1)
		else
			anim["frontrun"]:AdjustWeight(Z*-1.1)
			anim["frontwalk"]:AdjustWeight(1-((agility.Value/10)-1))
		end
	elseif Z > 0 then

		humanoid.WalkSpeed = agility.Value/2
	end
	if X == 0 then

	elseif X < 0 and not UIS:IsKeyDown(Enum.KeyCode.W) and not UIS:IsKeyDown(Enum.KeyCode.S) then
