ruby - Pick two different items randomly from an array -

in fighting program, have 2 players in array:

players = [brad, josh] 

i want randomly select 2 distinct players, 1 of attack other, schematically this:

random_player.attack(other_random_player) 

i want make sure players never attack themselves. if do:

players[rand(0..1)].attack(players[rand(0..1)]) 

there chance 1 player fight itself. how make once first player chosen , fights remaining player(s) array?

you use .sample:

match = players.sample(2); match[0].attack(match[1]); 

this randomly pick 2 players array, have them fight each other. there no way same player picked both.

more cleanly:

p1, p2 = players.sample(2) p1.attack p2
