d2clone-kit

Diablo 2 is arguably one of the best action RPG created ever. This is humble
attempt to recreate and, hopefully, deconstruct it using Common Lisp
programming language and related techniques.

• Support for Tiled map format.
• Support for Aseprite sprite format.
• Support for CastleDB database format.
• Performant Entity-Component-System implementation supporting
  parent-child entitiy relationships.
• Prefab subsystem allowing creation of new components using
  predefined file-backed template.
• Simple yet powerful events subsystem.
• Full-blown game character subsystem.
• Simple actions subsystem, providing building blocks for complex
  character behaviour.
• Basic game session utilities.
• 2D renderer with functional interface.
• Sprite batching subsystem.
• Simple DSL for creating GUI windows by
  Nuklear library.
• Naïve implementation of A* pathfinding algorithm.
• Powerful debugging facilities, including entity tree dumping and
  visual debugging.
• Loading assets from zip files.
• Simple yet versatile configuration subsystem.
• Logging subsystem.

d2clone-kit requires liballegro to function. To install
liballegro, refer to your distribution’s package manager; for instance, on
Debian derivatives (including Ubuntu and Mint):

sudo apt-get install liballegro-acodec5.2 liballegro-audio5.2 \
    liballegro-image5.2 liballegro-dialog5.2 liballegro-ttf5.2 \
    liballegro-physfs5.2 liballegro-video5.2

Currently the following Common Lisp implementations are tested and supported by
d2clone-kit:

• SBCL
• CCL
• ECL

You can run it on x86_64 Linux, macOS, and Windows, while SBCL on Linux is the
recommended platform.

To install d2clone-kit, clone the repository to your Quicklisp’s
local-projects directory (assuming you have
Quicklisp installed):

$ git clone https://gitlab.com/lockie/d2clone-kit \
    ~/quicklisp/local-projects/d2clone-kit
$ sbcl --quit --eval \
    "(progn (ql:register-local-projects) (ql:quickload :d2clone-kit))"

• action – abstraction of a multi-frame action performed by an
  entity. Unless stated otherwise, action is represented with its global index.
• isometric coordinates – coordinates in isometric projection.
• orthogonal coordinates – floating point in-game world coordinates. One
  unit of length corresponds to one map tile width, typically 64 pixels.
• prefab – system-specific object loaded from file and used as a template
  to create new instances of system’s component.
• screen coordinates – integer screen pixel coordinates.
• viewport coordinates – screen pixel coordinates relative to the current
  camera position.
