Works, but how can I find the character that has shot the weapon from a server script?

local Tool = script.Parent.Parent
debounce = false
local Muzzle = Tool.Muzzle.PointLight
local FireSound = script:WaitForChild("FireSound")
local HitSound = script:WaitForChild("HitSound")
local CS = game:GetService("CollectionService")
local player = game.Players.LocalPlayer



game.ReplicatedStorage.RayCastEvent.OnServerEvent:Connect(function(Player,FromP,ToP)
	local RayCast = Ray.new(FromP,(ToP-FromP).unit*100)
	local ignore = workspace:GetChildren();
    table.insert(ignore,player)
	local Part = game.Workspace:FindPartOnRayWithIgnoreList(RayCast,workspace.Camera:GetDescendants())
	FireSound:Play()
	if Part and debounce == false then
		local Hum = Part.Parent:FindFirstChild("Humanoid")
		Hum:TakeDamage("20")
		HitSound:Play()
		Muzzle.Enabled = true
		wait(0.1)
		debounce = true
		wait(0.1)
		Muzzle.Enabled = false
		debounce = false
	end
end)

Edit 2 : I have fixed my old issue, now though I need to find a way to make the script ignore local player (This is problematic because you cannot find character from a server script, so, is there anyway I can make this server script make sure that the ray ignores the player who shot the gun?

This is the local part where the event is fired

local UnequipEvent = game.ReplicatedStorage.Folder.Unequipped

EquippedEvent.OnClientEvent:Connect(function()
	Fired = true
end)
UnequipEvent.OnClientEvent:Connect(function()
	Fired = false
end)

player.Character.Humanoid.Running:connect(function(speed) --I hope player is a variable of an actual player.
	    if speed <= 16 and humanoid.Jump == false then --If they are not walking,

                 Running = true

	end)

	        Ammo = 30

	end
end)

Before firing event in local script you need a line like that:
