How do I make a hammer that destroys GameObjects when I'm touching them and have left clicked?

I have tried using a global variable to be true when I left click, but it doesn't work. Can someone please help?

You can use a RemoteEvent for this.

RemoteEvent Code:

• make a remote event
• put this as a server script in serverscriptservice

local whitelisted = {
"BlinkyGamer99YT",
"Player1"
}


game.ReplicatedStorage.RemoteEvent.OnServerEvent:Connect(function(target, localname)
if table.find(whitelisted, localname) then
     target:Destroy()
    end
end)

LocalScript Code:

• put in player GUI or starter scripts

local player = game.Players.LocalPlayer
local Mouse = player:GetMouse()
local waitforevent = game.ReplicatedStorage:WaitForChild("RemoteEvent")

Mouse.Button1Down:Connect(function()
  game.ReplicatedSotrage.RemoteEvent:FireServer(Mouse.Target, player.Name)
end)
