EnterName and HighScore GameStates not working as expected

[RyanPadveen]

I get a black screen. Am I using these GameStates correctly?

require 'rubygems' rescue nil
$LOAD_PATH.unshift File.join(File.expand_path(__FILE__), "..", "..", "lib")
require 'chingu'
include Gosu
include Chingu

class Game < Chingu::Window
  def initialize
    super
  end
  def setup
    switch_game_state(MainState)
  end
end

class MainState < Chingu::GameState
  def initialize
    super
    $name = "Player"
    $points = 500
    $high_score_list = Chingu::HighScoreList.load(:size => 10)
    $window.push_game_state(GameStates::EnterName.new(:callback => method(:got_name)))
  end

  def got_name(name)
    $name = name
    $newscore = $high_score_list.add({name: $name, score:   $points})
    puts "Got name: #{name}"
    pop_game_state
    $window.switch_game_state(HighScores)
  end
end

class HighScores < Chingu::GameState
  def initialize
    super
    create_text
  end

  def create_text
    $high_score_list.each_with_index do |high_score, index|
      y = index * 25 + 100
      Text.create(high_score[:name], :x => 200, :y => y, :size => 20)
      Text.create(high_score[:score], :x => 400, :y => y, :size => 20)
    end
  end
end

Game.new.show

does example16_online_high_scores.rb or example13_high_scores work for you?

[RyanPadveen]

@ippa example13_high_scores.rb works perfectly. example16_online_high_scores.rb mostly works, but it crashes sometimes when I press R.
