How do you make your own admin commands script on roblox with no free models

idk what u mean by no free models but i kinda have an idea so ik how to make one.....

vip = game.Players.NAME function onChatted(msg) if msg == "kill/me" then game.Workspace.NAME.Head:remove() end end vip.Chatted:connect(onChatted)

to change what u have to say to make something happen is the "kill/me" part
switch NAME with ur username of course and put in ur own script where it says game.Workspace.NAME.Head:remove()
