Aiming in 2d space

[EpicScarGaming121 (spoon)]

How would I be able to allow my character to aim up and down depending on mouse location?

Example: Mouse in top right corner allows the character to aim in the top right direction.

local Player = game:GetService("Players")
local player = Player.LocalPlayer
local Character = player.Character or player.CharacterAdded:Wait()
local mouse = player:GetMouse()
local pp = Character.HumanoidRootPart

while wait() do
	
	pp.CFrame = CFrame.new(pp.Position, Vector3.new(mouse.Hit.p.X, pp.Position.Y, mouse.Hit.p.Z))  -- If you want a in-depth cframe  tutorial on what this line does click the link below
end

CFrame lookVector point to target: lookAt()

" CFrame.new( Vector3 pos, Vector3 lookAt )" is apparently deprecated (I don’t know why they would do that with no easy/simple alternative) according to the wiki, and gives the function below as a way to achieve the same effect. However, it seems to be looking away from the target. Here’s a test place. Click play, switch to server view, and drag around either part (I’ve marked the front surface of the light gray part with a different surface type to show which way it’s facing). function lookAt…

If you want the script to work in server you’ll place the same thing but either use remoteEvent or a RemoteFunction to get mouse to the server.

While this was not what I wanted, I edited the script to help aim with only the X and Y axis. Its getting close, but not that good.

this is what i want to acomplish with aiming.

After a lot of blood, sweat, and tears, i have finally made it so i can aim on 2 axis after using your answer and this guide.
