尝试用Common Lisp写游戏

以前刚学C++的时候,学会了循环和条件语句后,就用控制台写了个黑简单的,文字显示的RPG打怪升级的"游戏".

哈哈哈,相当简单,进去时候输名字选职业,然后就随机遇怪,打了得经验,可以升级.完了.

不过那时候还是黑兴奋诶,而且后来学校里面那些问怎么开始学习游戏,我都说的这个来练习.

 

现在试看用CL来写看,前面看的数据库的黑多部分可以拿来用.

写了哈游戏主函数和游戏循环.明天写其他的.

 

不晓得囊个的用Emacs来显示文本的时候,如果直接用中文字符串显示是乱码,但是如果输入的是中文显示是正常,可能Emacs配置不对.

先不管了英文不影响效果.

 

下面是代码

(defun game-main () (create-role) (game-run)) (defvar *player* ()) (defun make-role (name job) (list :name name :job job :hp 100 :atk 5 :def 3)) (defun save-role (role) (setf *player* role)) (defun show-role () (format t "~{~a:~2t~a~2t~}~%" *player*)) (defun read-info (info) (format *query-io* "Enter Your ~a: " info) (force-output *query-io*) (read-line *query-io*)) (defun create-role () (save-role (make-role (read-info "Name") (read-info "Job")))) (Defun game-run () (loop (game-loop) (if (want-over) (return)))) (defun game-loop () (show-role)) (defun want-over () (format t "Enter q or Q GameOver:") (equal 'q (read *query-io*)))

现在游戏循环只是简单的显示玩家信息

今天又写了哈,随机遇怪,战斗,有暴击,战斗结束得的到经验,恢复血.

大致熟悉了哈写的方式,因为还不晓得局部变量之类的东西有没,所以有些函数要多次用到同一个变量的时候,都是当参数传入的.

 

还有昨天那个中文显示问题,估计应该是slime的问题,用了Emacs和Slime的时候才这样.直接用ccl加载fasl文件中文都是正常显示的.

 

下面是今天的代码

(defun game-main () (create-role) (game-run) nil) (defvar *player* ()) (defun make-role (name job exp hp atk def) (list :name name :job job :exp exp :hp hp :atk atk :def def)) (defun save-role (role) (setf *player* role)) (defun show-role (role) (format t "Your ~{~a:~2t~a~2t~}~%" role)) (defun read-info (info) (format *query-io* "Enter Your ~a: " info) (force-output *query-io*) (read-line *query-io*)) (defun create-role () (save-role (make-role (read-info "Name") (read-info "Job") 0 100 15 3))) (Defun game-run () (loop (game-loop) (if (game-over?)
