All,
I am trying to create a two dimension array in Ruby. The books I have
referred two doesn't give me any examples on how to create a two dimension
array by a programmatic way. They do talk about creating it by hard code.
The below method is trying creates a 3 by 3 array with a random number
between 0 to 1.
def create_world x, y
col = Array.new
row = Array.new
counter_x = 0
counter_y = 0
while (counter_x < x)
puts 'x ' + counter_x.to_s.to_s
while (counter_y < y)
puts 'y ' + counter_y.to_s
map_type = rand(2)
puts 'Random: ' + map_type.to_s
row.push map_type
counter_y = counter_y + 1
end
col.push row
counter_y = 0
counter_x = counter_x + 1
end
return col
end
world = create_world(3, 3)
puts world.to_s
puts 'array ' + world[0].size.to_s
Problem with code above is:
1. I get 3 rows. But in each row I get 9 columns.
2. Each row content is the same.
So can anyone help with the above?
