When in some servers I notice the admins change some settings. Here are some questions I'd like to ask.

1. How do you turn damage off for all players?
2. In some servers I've noticed admins are in "God Mode". How do you activate this?
3. And finally, how do you turn damage off for blocks?

I am new to this site, so please excuse me if i called something by the wrong name.

some servers are different than others like the one i am trying to setup called pyspades allows you to do those options unlike a vanilla server

im just guessing its a pyspades server

if your on pyspades server, just type /help for all commands

1. put everyone on god mode by typing /god (player name or number) and do that to each player
2. number 1 is god mode
3. this is also god mode

For number 1 and 3 the commands to use are /togglekill and /togglebuild

Oh I see, thank you all.
