[ruby-talk:444595] Montreal.rb Hack Night Solutions for Hunt The Wampus
by Andy Maleh 09 Dec '24

09 Dec '24

In November and December of 2024, Montreal.rb hosted 2 Ruby Hack Night meetups about building the historic computer game, Hunt The Wampus, which was a text-based adventure game developed by Gregory Yob in 1973. A GitHub repo has been provided with solutions, which include the Ruby code for the Model layer, a desktop GUI View layer, and a Rails Web Frontend View layer: https://andymaleh.blogspot.com/2024/12/montrealrb-hack-night-solutions-for.… https://raw.githubusercontent.com/AndyObtiva/hunt_the_wampus/refs/heads/sol…

[ruby-talk:444594] [ANN] graphics 1.1.2 Released
by Ryan Davis 07 Dec '24

07 Dec '24

graphics version 1.1.2 has been released! * home: <https://github.com/seattlerb/graphics> * rdoc: <http://docs.seattlerb.org/graphics> Graphics provides a simple framework to implement games and/or simulations and is designed to follow mathematical conventions, NOT game programming conventions. Particularly it: * Uses degrees. * Draws in quadrant 1 (0-90 degrees). * Right hand rule: 0 degrees is east, 90 is north, etc. These allow simple things like Trigonometry functions to work as expected. It means that all that stuff you were taught in grade school still work as intended. This makes one less thing you have to adjust when implementing your simulation. Changes: ### 1.1.2 / 2024-12-07 * 1 minor enhancement: * Bumped required ruby version. * 3 bug fixes: * Fixed bad copy/paste in setup script. (havenwood) * Fixed color handling in polygon. * Fixed frozen string literal in examples/editor.rb

This is major development update including a lot of bug fixes (no? really?), changes, improvements and extensions. **wxRuby3/Shapes** (Wx::SF) is a pure Ruby 2D shapes and diagramming software library/framework based on wxRuby3 which allows easy development of software applications manipulating graphical objects (shapes) like various CASE tools, technological process modeling tools, etc. ## What's changed * refactor the serialization code into a separate gem [FIRM](https://github.com/mcorino/firm) with it's own improvements, optimizations and extensions (like XML serialization) * add many new arrow types (square, prong, cross-bar, etc. and combinations) * add BoxShape (incl. VBoxShape and HBoxShape) shapes with similar child management as wxRuby's BoxSizers * major changes and extensions of the 'demo' sample * lots of other changes, bug-fixes and optimizations Github: https://github.com/mcorino/wxRuby3-shapes Github-pages: https://mcorino.github.io/wxRuby3-shapes Rubygems: https://rubygems.org/gems/wxruby3-shapes
