Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased

Added

  • SYSTEM-REF helper re-added for loose coupling reasons.
  • Priorities of CastleDB tables.
  • Default value for font configuration variable.
  • Interactive restarts for ENSURE-LOADED to specify another file name and retry loading.
  • Interactive restart for game loop to proceed to next iteration.
  • PACKAGE-VERSION helper to get package versions from asdf.
  • Ability to create coordinates component with :ISO-X and :ISO-Y arguments.
  • Support for Tiled objects' type (point, ellipse, polygon, rectangle).
  • Ability to draw debug ellipses.
  • Movement target indicator for debugging.
  • Ability to load game objects from Tiled objects.

Changed

  • Changed syntax of WITH-SYSTEM-SLOTS macro to be more DSL-ish.
  • Changed inlined functions to be uninlined in debug mode.
  • Load all CastleDB .cdb files instead of the one specific for the game.
  • Improved error handling of .cdb file loading.
  • Removed source file and line output from log.
  • Supply correct file mode to al_fopen in BINARY-STREAM.

Removed

Fixed

  • Fixed compilation warnings, slightly improving performance.
  • Minor performance improvements in game loop.
  • Fixed bug causing broken lisp image stuck at "filesystem already initialized" error when there was a condition in system initialization.
  • Minor performance improvement in loading of text resource files.
  • Fixed audio crash when using Pulseaudio by enforcing OpenAL allegro backend.

0.1.1 - 2021-08-07

  • MacOS support.
  • Helper function to do proper error checking on liballegro file loading.
  • Proper collision map clearing on map chunks deletion.
  • System initialization method.
  • Game session control functions (NEW-GAME, GAME-STARTED-P, EXIT).
  • READ-FILE-INTO-LIST helper to be used in credits screen.
  • GUI system DSL based on Nuklear library.
  • Main menu.
  • Credits screen.
  • Parent-child relationship in ECS entities.
  • Actions subsystem.

  • Random sound effect variablility.
  • Attack impact sounds.
  • Mention of engine version in the log.

Changed

  • Removed ubiquitous mana system component.
  • Refactored coordinates system. Now orthogonal coordinates are stored and used everywhere, and isometric ones are calculated on the fly when needed.
  • Removed ubiquitous coordinates component.
  • Removed ubiquitous sprite batch system component.
  • Refactored new game object initialization to avoid runtime code generation.
  • DEFPREFAB macro now also defines necessary empty MAKE-COMPONENT method.
  • ECS systems refactored to use DEFSTRUCTs for performance reasons.
  • Refactored invalid entity mechanics.
  • ECS components refactored to sparse SoA arrays for performance and memory consumption reasons.
  • Radically simplified events subsystem.
  • Delta time between frames is now a global variable.
  • Mob health bar and item text drawing refactored out of player system.
  • Refactored sprite frame time calculation.
  • Comply with ECS system order when initializing component in MAKE-OBJECT.
  • Comply with ECS system order when finalizing systems.
  • Forced the 80 columns limit on all source code files.
  • Prevented unwanted symbol interning.

Removed

  • Obsolete console-system stub.
  • QUIT event in favour of plain SYSTEM-FINALIZE method.
  • SYSTEM-REF replaced with global-vars for performance reasons.
  • Removed cl-static-dispatch library usage.

Fixed

  • Fixed compilation on CCL.
  • Assets are now loaded using path relative to executable, not to current working directory.
  • Minor performance improvements in asset loading.
  • Fixed bug causing FLOATING-POINT-INVALID-OPERATION on some systems.
  • Greatly improved memory usage by avoiding storing parsed ase files.
  • Fixed bug causing log messages with % symbol to be output incorrectly.
  • Fixed bug causing log messages longer than approx. 2kbytes to be truncated.
  • Fixed bug causing character shadow to be drawn over the weapon.
  • Fixed bug causing character to be able to move through other characters.
  • Fixed bug causing player character not being able to stop the initiated attack.
  • Fixed item-related performance issue.
  • Greatly improved sprite batch performance.
  • Fixed bug causing item sprite batch to be still drawn when item was picked up.
