What is the easiest way to find the player in a PVP setting?

So basically I've always had trouble finding the player while making a few games. Right now I'm trying to make a game where one player can use a tool to summon a block and when that block hits another player it damages them. How I'm finding the player right now is really convoluted and I feel there is probably a much easier way. What I'm doing to get the player is making it so that when a player joins, a StringValue records their name and then I get that name from the StringValue by using FindFirstChild in ReplicatedStorage (where the StringValue is located). Here's the script:

game.Players.PlayerAdded:connect(function(player)
local stat = Instance.new("StringValue",  game.ReplicatedStorage)
stat.Name = "NameVal"
stat.Value = player.Name
end)

and here's the script for when the player is hit with the block:

local part = script.Parent
local name = game.ReplicatedStorage:FindFirstChild("NameVal").Value
local player = game.Players:FindFirstChild(name)
local char = game.Workspace:WaitForChild(name)

function onTouch(hit)
	if hit.Parent:FindFirstChild("Humanoid") then
		if hit.Parent:FindFirstChild("Humanoid") == char.Humanoid then
			return
		end
		hit.Parent:FindFirstChild("Humanoid").Health = hit.Parent:FindFirstChild("Humanoid").Health - 10
	else
		return
	end
end

part.Touched:connect(onTouch)

Please inform me if there's a better way of handling this. I'm pretty new to scripting and I'd appreciate any feedback given. Thanks.
