What to use instead of 'getPlayer'?

script.Parent.Touched:connect(function(Part)
    if Part.Parent:FindFirstChild("Humanoid") then
        local player=getPlayer(Part.Parent)
        game.ReplicatedStorage.Tool:clone().Parent=player.Backpack
    end
end)

I wouldn't know what to use instead of 'getPlayer' for the third line of code as it says it is an unknown. I was attempting to create a script that would clone a tool into the player's backpack on touch of a specific brick.

You're looking for the GetPlayerFromCharacter method of game.Players:

script.Parent.Touched:connect(function(Part)
    if Part.Parent:FindFirstChild("Humanoid") then
        local player=game.Players:GetPlayerFromCharacter(Part.Parent)
        game.ReplicatedStorage.Tool:clone().Parent=player.Backpack
    end
end)

Try using the GetPlayerFromCharacter method of Players

The script below should fix your issue:

script.Parent.Touched:connect(function(Part)
	if Part.Parent:FindFirstChild("Humanoid") then
	local player=game.Players:GetPlayerFromCharacter(Part.Parent)
		game.ReplicatedStorage.Tool:clone().Parent=player.Backpack
	end
end)
