Making a dice in ruby language

Im coding a dice in ruby in which when i rolled it, it would either come up north south east or west.

what im having trouble with is when i roll it how do i tell it to return to 开发者_高级运维me one of these directions?

any help would be great.

Use Array.sample:

[ 'north', 'south', 'east', 'west' ].sample

It doesn't get much easier than %w(north south east west).sample (that's 1.9 method btw). Another thing that works in 1.8 and 1.9 is %w(north south east west)[rand(4)].
