I was making a kill on sight command, when you executed the kos command to a player, it will show up, if you executed the revoke kos command to a player, the kos will be removed. Kos by the way is Kill on Sight.
Script:
local kos = script.KoS:Clone()
game.Players.PlayerAdded:Connect(function(plr)
plr.CharacterAdded:Connect(function(char)
plr.Chatted:Connect(function(msg)
if msg == "kos ".. plr.Name then
kos.Parent = char.Head
elseif msg == "revoke kos ".. plr.Name then
kos.ImageLabel.Visible = false
end
end)
end)
end)
