Just like the "or" command, the "and" command allows several conditions to be checked. Example:
if(alive player and speed player > 0 and _someOtherVar) then { hint"All three condtions are true" }; The example above will check if the player is alive and if the player is moving and checks if _someOtherVar is true.
