erlang - Create a mini-delay before each recursion in Erlang?

Question

For some of my foolish reasons and monotony, How do I create a half second delay before each recursion?

Answer 1

Pascal 是对的，但如果您不需要接收任何消息以提高可读性，请使用timer:sleep/1。这个函数的作用完全相同。

Answer 2

使用接收块的 after 语句

wait_ms(X) when is_integer(X) ->
    receive
    after X ->
        done
    end.
