I would like to know how to change properties of all player characters in a game. For instance, how to delete all torsos from all characters. I know how to do :GetAllPlayers, but with that you can't change any properties.
I have made a post on your previous question on how to GetAllParts, this is no different.
Also please read the previous post so you will get this one
for _, player in pairs(game.Players:GetPlayers()) do if player.Character:FindFirstChild('Torso') then player.Character.Torso:Destroy() end end
Note this will only work for R6, for R15, you would have to change Torso to a part that R15 has, note that this many kill the player.
Please read the previous posts answer and you will understand more.
