Beta 2 of Hands-on Rust is now available

Beta 2 adds chapters entitled Health and Melee Combat, and Victory and Defeat, as well as some errata. Learn to track hit points, for both the player and monsters. Add a heads-up display. Find the lost amulet, or die trying.

The new chapters are focused on state management, and structuring your game to support different modes.

New chapters added:

• Health and Melee Combat
• Victory and Defeat

This release also includes the following changes:

• Clarified the placement of the stdin call.
• Changed references from cargo init to cargo new to reflect the preferred usage of the tool.
• Added an aside explaining why you create a new String before passing it to read_line.
• Added discussion about Rust’s handling of trailing commas in lists.
• Fixed capitalization of set().
• Changed _ctx to ctx.
• Added a small section to chapter 2 discussing enum initialization.
• The map_render code used from Chapter 5 onwards is more efficiently structured.
• Added instructions to insert the Collision System into your scheduler.
• Added a note that the map_idx function should be implemented outside of the Map structure’s implementation block.
• Expanded the code example in “Consume the Map API” to include the main function.
• Corrected an issue in the source code in which camera.rs changed the function signature of on_player_move in later chapters.
