I'm not sure how to add in a new Part, PointLight, or any other object with scripting. Can you please give me a link to the page where I can find out more information on that? I need it to be InstanceNew("Part") or something like that. I also need to know how to make it go into another part so that the part is it's parent. I need to learn that so that I make a script that adds a PointLight to all players' torsos.
wait(5) -- Waits 5 seconds until script starts for i,v in pairs (game.Players:GetPlayers()) do Instance.new("PointLight").Parent = v.Character.Torso end
Put this script in Workspace this adds a PointLight to the torso of all the player's at one time.
+1 if this helped!
