How can you get a player to look at a part?

You should be able to do this with by tweening the player's humanoid root part to look at the part. It can be done seen here:

local lookAt = script.Parent -- Part.
local tweenService = game:GetService("TweenService")
local basicTweenInfo = TweenInfo.new(0.01) -- Tween time.

game.Players.PlayerAdded:Connect(function(player)
    player.CharacterAdded:Connect(function(character)
        wait(5) -- To make sure the character is on the ground before doing this.

        local root = character:WaitForChild("HumanoidRootPart")

        spawn(function()
            while true do
                wait()
                tween(root)
            end
        end)
    end)
end)

function tween(part)
    local tweenGoals = {
        CFrame = CFrame.new(part.CFrame.Position, lookAt.CFrame.Position)
    }
    local createTween = tweenService:Create(part, basicTweenInfo, tweenGoals)
    createTween:Play()
end

May be a little shaky but this is only a written example.

Nvm I have stupid, if anyone else wants to know what I did just use this

local Object = Vector3.new( Target.Hitbox.Position.x, Target.Hitbox.Position.y, Target.Hitbox.Position.z )

TroopA[3].HumanoidRootPart.CFrame = CFrame.new( TroopA[3].HumanoidRootPart.Position, Object )
