It just comes to doing a loop over every player to either clone or destroy the tool.
local toolName = "Camera"
for _,player in pairs(game.Players:GetPlayers()) do
for _,tool in pairs(player.Backpack:GetChildren()) do
if tool.Name == toolName then
tool:Destroy()
end
end
if player.Character:FindFirstChild(toolName) then --This is done in case the player has the tool equipped
player.Character[toolName]:Destroy()
end
end
