Requirements

  • x86_64 Windows, GNU/Linux or macOS
  • OpenGL 2.1 or 3.3+
  • x86_64 SBCL or CCL
  • Quicklisp

How to install SBCL or CCL

  • Go to http://www.sbcl.org or https://ccl.clozure.com and download the tool.
  • After sbcl is installed you can call it with the command sbcl from command line.
  • After ccl is installed run the exe in the folder and you are ready to go.

How to install Quicklisp

  • Go to https://www.quicklisp.org ad download ´quicklisp.lisp´
  • While sbcl or ccl is running enter the command (load "c:/somewhere/path_to_where_you_downloaded_quicklisp.lisp")
  • Quicklisp will be installed into your user folder.
  • Run the command (load "~/quicklisp/setup.lisp") to start setup.
  • Run the command (ql:add-to-init-file) to load quick lisp automatically when you run sbcl or ccl.

How to Run

To run from REPL, clone project into ~/quicklisp/local-projects/ and run the following commands.

(ql-dist:install-dist "http://bodge.borodust.org/dist/org.borodust.bodge.testing.txt")

(ql:register-local-projects)

(ql:quickload :moppu) (moppu::run)

moppu's Issues

local variables

small improvement to your code: in Common Lisp setting a variable is a different operation from defining it.

(defun check-collision-all (item)
  (setf collides nil)
  (loop
    :for elem :in (nth (- *game-state* 2) *levels*)
    :when (check-collision item elem)
    :do (setf collides t))
  collides)

You have that pattern in your code elsewhere, too. load-level and check-collision for example.

SETF does not define a variable, but sets it only. To define a function local variable one has two options: let and (not that often seen) &aux:

(let ((collides nil))
  (loop ... (setf collides t) ...)
  collides)

or

(defun check-collision-all (item &aux (collides nil))
   (loop ... (setf collides t) ...)
   collides)

Otherwise collides possibly would be a global and undefined variable. A Common Lisp compiler will typically warn about that.
