@Robert strange that you’re having that problem; I used Cygwin and I can recall lots of case problems. Sorry about that.

Glad to hear it helps; the line-of-sight algorithm was particularly tricky. Sorry, the code is not that great

Hi,

it seems you developed the game in an environment without case-sensitive filenames. Because when I try to run it under Linux it fails with a lot of dangling requires due to casing issues.

Besides this, I am glad to see the source code of roguelike developed in Ruby since I am currently developing one myself in this fine language.

Here’s how to do an inline style declaration along with link_to image_tag, and with text!:

image.name, :title=> image.name, :height=>”64px”, :width=>”64px”) + image.name), “url”, :style=>”text-decoration:none;” %>

Hi,
I am looking for relevant material and I found your website “http://www.railsrocket.com/” really informative.
I would like to do business with you. I basically have an offer of buying text-links on your site.
Let me know if you would be interested in hearing more.

Best regards,

Dennis

Comment on Many-to-Many Association by Riccardo

In Course class this:

has_and_belongs_to_many :courses

is wrong. That is correct:

has_and_belongs_to_many :students

A course has to point to many students, not himself.

Why don’t you do price < 0.01.to_d instead so that it will compare using bigdecimal instead of float.

Comment on Formatting Decimals by Andy

You’ve mixed up the formatting string and the argument to be formatted. It’s the other way around: sprintf (format_string, arg)

Comment on Rails 2.1: Named Scope by Kirk Bushell

ashes – models only get loaded once – when the server starts. As a result, any code that isn’t run at runtime (this includes behaviours, relationships/associations, scopes.etc.) only get evaluated once the server has started.
