The graphics are now displayed +using Lispbuilder \url{http://lispbuilder.sourceforge.net}'s libraries, +so the problems with portability from CMUCL and X Window Sistem do +not exist anymore. Also the code is cleaner and more extensible. +\end{abstract} +\tableofcontents{} + + +\section{Introduction} + +The Feebs are intelligent and hostile creatures that live inside maze +tunnels. They also have no mercy with each other, so they frequently +throw a letal flame from through their mouth, getting rid of their +opponent and eatting the carcass left. But throwing flames have an +energy cost, so they must keep tracking for food. + +This game is intended to help lisp newbies (or maybe a little more +advanced lispers) to learn lisp. A player must create a function that +receives what his/her feeb is seeing and feeling, and returns what +it will do next. To create the better feeb, one can create variables +to store data from previous moves (or not), and can also use all the +power of lisp to improve his/her creature. But the most important +is to make good choices and be aware of danger! + + +\subsection{Changes from \emph{Planet of the Feebs}} + +Many changes were made from the original game, but, if you have any +feeb definition and you want to use it, it should be easy to adapt +the brain function to the new rules. + +The main reason of this project is that \textit{Planet of the Feebs} +is really interesting for (not just) newbies to learn lisp, but the +difficulties to install, unportability and the ausence of competitors +make it difficult to someone to be interested in making a feeb. So, +I hope that making these adjustments and maybe creating some contests +over the web make people be more interested in learning lisp. + +So, these are (some of) the changes: + +\begin{itemize} +\item The graphics are not based on X Window Sistem anymore, but on \textit{Lispbuilder}, +and there are no CMUCL's event handler. This way, the code is more +portable and graphics can be improved. Just creating some image +files of a feeb and your feeb is much more personalized! +\item Every element of the map (including walls) is a list, so the brain of +a feeb doesn't need to test all the time if the element is an atom +or a list (wich, in my opinion, is really boring, unlispy and unnecessary +in this case). That was only a reason to duplicate code and work, +adding no results at all... +\item Many functions and variables are changed and others were added +\item Documentation is more objective than the one provided with \textit{Planet +of the Feebs}, and is fully compatible with the code. This way it +is easier to understand the game. +\item Security is improved. Now it the behavior functions are allowed to store +and change structures and vectors passed to it. +The parameters can't be change by those functions while inside the game. +\item It is possible now to extend the rules: the code is object oriented and +new rules, special moves, change the behavior of flames, etc, can be done +by adding new classes and/or methods. This manual is just the beginning! +end{itemize} + +\section{The Game} + + +\subsection{Overview} + +Your feeb's objective is to survive and kill other feebs. It is inside +a maze of tunnels. Every turn, all feebs lose one unit of energy, +and maybe starves. Your feeb is able to move forward, turn left, right +or around, flame, peek around a corner, eat something or just wait. +After all feebs move, the flames thrown before also move (or dissipate), +carcasses may rot and mushrooms may grow, accordingly to some rules. + +The game rules are defined by parameters. These parameters can be read +by the command \textsf{\textbf{(get-feeb-parm~}'parameter\textbf{)}} +To see all parameters, values and also all the documentation, one can use +\textsf{\textbf{(list-parameter-settings)}}. Using +\textsf{\textbf{(change-feeb-parm}'parameter~value\textbf{)}} +gives the possibility to change them (but not during the game) and +\textsf{\textbf{(documentation~}'parameter~'feeb-parm\textbf{)}} +can be used to know them. Just remember that every probability +must be a rational number (like 1/2). + +But don't panic! These parameters are just for one to know how +the game is going to be, but in the begining there is no need +to explicitly use them when creating the brain of a feeb. +The best way to create a feeb is watching a game (among system feebs), +improving it (it is defined in file brains.lisp) a little more, +testing the changes... + +These are some global parameters: + +\begin{lyxlist}{00.00.0000} +\item [{\textsf{\textbf{'game-length}}}] Number of turns the game +will last. +\item [{\textsf{\textbf{'points-for-killing}}}] How many points some +feeb earn for killing someone. +\item [{\textsf{\textbf{'points-for-dying}}}] How many points some +feeb earn for dying (usually negative). +\item [{\textsf{\textbf{'maze-x-size}}}] Horizontal size of the maze. +\item [{\textsf{\textbf{'maze-y-size}}}] Vertical size of the maze. +\end{lyxlist} + +\subsection{Throwing flame} + +If a feeb decides to throw a flame, if it is prepared to and has +enough energy, the next turn there will be a flame in the square +in front of the feeb, and it will see it, so the feeb shouldn't move +forward. For a few turns, the feeb will not be able to +throw flames. Each turn, the flame moves forward destroing mushrooms and +killing feebs it encounters, transforming them into carcass. If there +is a wall, the flame can reflect, and, if so, it will turn 180 degrees. + +Once a feeb is killed (or starves), in it's place in the maze there will appear +a carcass. The feeb goes to the end of the dead feebs line. When the +carcass rots, the first feeb in line reincarnates. So, dying is not so terrible. + +These are the parameters related to flames: + +\begin{lyxlist}{00.00.0000} +\item [{\textsf{\textbf{'flame-energy}}}] Amount of energy lost after +throwing a flame. +\item [{\textsf{\textbf{'fireball-guaranteed-lifetime}}}] Number of +turns that a fireball is guaranteed not to dissipate, unless it encounters +a wall. +\item [{\textsf{\textbf{'fireball-dissipation-probability}}}] Probability +of the flame to dissipate each turn after the apropriate time. +\item [{\textsf{\textbf{'fireball-reflection-probability}}}] Probability +of the flame to reflect when encountering a wall. +\item [{\textsf{\textbf{'flame-no-recovery-time}}}] Number of turns +that a feeb cannot fire. +\item [{\textsf{\textbf{'flame-recovery-probability}}}] Probability +of the feeb to recover the hability to throw a flame, after the apropriate +time. +\end{lyxlist} + +\subsection{Eating food} + +There are two kinds of food, carcasses and mushrooms. Carcasses usually +give less energy than mushrooms, and may rot, but, while it does not +rot, a feeb can feed as long as it wishes. Mushrooms disapear after +being eaten. By eating food, the feeb +will be able to recover energy, wich is important because, if a feeb +stays with 0 or less units of energy, it starves. + +These are the quantities: + +\begin{lyxlist}{00.00.0000} +\item [{\textsf{\textbf{'mushroom-energy}}}] Amount of energy recovered +when the feeb eats a mushroom. +\item [{\textsf{\textbf{'carcass-energy}}}] Amount of energy recovered +each turn that the feeb eats a carcass. +\item [{\textsf{\textbf{'carcass-guaranteed-lifetime}}}] Number of +turns that a carcass will surely not rot. After these turns, it +can rot, depending on probabilities. +\item [{\textsf{\textbf{'carcass-rot-probability}}}] Probability of +the carcass to rot, after the apropriate time. +\item [{\textsf{\textbf{'maximum-energy}}}] Maximum amount of energy +that a feeb can have eating. +\item [{\textsf{\textbf{'starting-energy}}}] Amount of energy a feeb +has when it reincarnates. +\item [{\textsf{\textbf{'number-of-mushrooms}}}] Quantity of mushrooms +that exist in the maze. +\end{lyxlist} + +\section{The Feeb} + +A feeb needs four things: a name, a brain and a set of graphics (optional). + +\begin{itemize} +\item The name, a string. +\item The brain is a function that decides what the feeb will do next, based +on what it is seeing and feeling. +\item The set of graphics is an image file (of format BMP, JPEG, PNG, and +any others that supported by SDL\_image). +\end{itemize} +One can create a feeb calling +\textsf{\textbf{(define-feeb}~name~brain~\textbf{:graphics}~graphics\textbf{)}}. +If name is already used, a warning will be signaled, and the old feeb +will be substituted. Calling \textsf{\textbf{(list-of-feebs)}} will +return the list of the feebs (names only) that will be defined when +the game begins. \textsf{\textbf{(delete-feeb}}\textsf{~name}\textsf{\textbf{)}} +will delete the feeb with this name from this list, and \textsf{\textbf{(delete-all-feebs)}} +will clear it. + + +\subsection{Possible decisions} + +After processing the information available, the brain will take a +decision. If this decision is not one of the decisions listed down, +a warning will be signaled, and the result will be like \textsf{\textbf{:wait}}. +Then, if someone are testing a brain function, he or she will be able +to know if something goes wrong. + +The possible values that the brain function can return are these: + +\begin{lyxlist}{00.00.0000} +\item [{\textsf{\textbf{:move-forward}}}] Move one square forward, unless +there is a wall in front of the feeb. +\item [{\textsf{\textbf{:turn-left}}}] Turn 90 degrees to the left. +\item [{\textsf{\textbf{:turn-right}}}] Turn 90 degrees to the right. +\item [{\textsf{\textbf{:turn-around}}}] Turn 180 degrees. +\item [{\textsf{\textbf{:flame}}}] Throw a flame. The flame will be created +next turn in the front square of the feeb. +\item [{\textsf{\textbf{:wait}}}] Do nothing in this turn. +\item [{\textsf{\textbf{:peek-left}}}] Peek to the left around a corner. +The creature does note actually move, but, in the next turn, the creature +will have the same vision that it would have if he had moved one step +foward and turned left (and one step back because the feeb needs to see +what is actually in front of it). Peeking used so a feeb can analize a corridor +before trespassing it. +\item [{\textsf{\textbf{:peek-right}}}] Peek to the right around a corner, +analogous to \textsf{\textbf{:peek-left}}. +\item [{\textsf{\textbf{:eat-carcass}}}] Eat a carcass if there is any +available in the feeb's square. The amount of the parameter +\textsf{\textbf{'carcass-energy}} is restored to the feeb's energy. +\item [{\textsf{\textbf{:eat-mushroom}}}] Eat a mushroom if there is any +available in the feeb's square. The amount of the parameter +\textsf{\textbf{'mushroom-energy}} is restored to the feeb's energy. +\end{lyxlist} + +\subsection{Information available} + +The brain of a feeb must take five arguments; I'll call them \textsf{\emph{status}}, +\textsf{\emph{proximity}}, \textsf{\emph{vision}}, \textsf{\emph{vision-left}} +and \textsf{\emph{vision-right}}. + + +\subsubsection{Status} + +Every time the brain is called, it receives some useful information +through \textsf{\textbf{status}}. + +The structure \textsf{\textbf{status}} keeps information about the +feeb itself. Also it has information of the previous movement of the +feeb. To access them, one must call: + +\begin{lyxlist}{00.00.0000} +\item [{\textsf{\textbf{(name}}\textsf{\emph{~status}}\textsf{\textbf{)}}}] \begin{flushleft} +The name of the feeb. +\par\end{flushleft} +\item [{\textsf{\textbf{(facing}}\textsf{\emph{~status}}\textsf{\textbf{)}}}] \begin{flushleft} +Where the feeb is facing to, one of the constants provided: \textsf{\textbf{north}}, +\textsf{\textbf{east}}, \textsf{\textbf{south}} or \textsf{\textbf{west}}, +wich are 0, 1, 2 and 3 respectivelly. +\par\end{flushleft} +\item [{\textsf{\textbf{(x-position}\emph{~status}\textbf{)}}}] \begin{flushleft} +The horizontal position of the feeb, starting with 0 and increasing to east. +If \textsf{\textbf{'sense-location-p}} is nil, it returns nil instead. +\par\end{flushleft} +\item [{\textsf{\textbf{(y-position}\emph{~status}\textbf{)}}}] \begin{flushleft} +The vertical position of the feeb, starting with 0 and increasing to south. +If \textsf{\textbf{'sense-location-p}} is nil, it returns nil instead. +\par\end{flushleft} +\item [{\textsf{\textbf{(peeking}\emph{~status}\textbf{)}}}] \begin{flushleft} +If it is \textsf{\textbf{:peek-left}} or \textsf{\textbf{:peek-right}}, it means +that the current \textsf{\emph{vision}} provided is result of a previous +\textsf{\textbf{:peek-left}} or \textsf{\textbf{:peek-right}} command +of the same feeb. Otherwise, it is \textsf{\textbf{nil}}. Note that +\textsf{\emph{proximity}} is \emph{not} affected. +\par\end{flushleft} +\item [{\textsf{\textbf{(line-of-sight}\emph{~status}\textbf{)}}}] \begin{flushleft} +Indicates the amount of valid entries in \textsf{\emph{vision}}. It actually +means that \textsf{\textbf{(aref}\emph{~vision~}\textbf{(line-of-sight}\emph{~status}\textbf{))}} +will return \textsf{\textbf{'(:rock)}}. +\par\end{flushleft} +\item [{\textsf{\textbf{(ready-to-fire}\emph{~status}\textbf{)}}}] \begin{flushleft} +If \textsf{\textbf{T}} indicates that the feeb is ready to fire. +If \textsf{\textbf{Nil}} indicates it is not. +\par\end{flushleft} +\item [{\textsf{\textbf{(aborted}\emph{~status}\textbf{)}}}] \begin{flushleft} +Related with timing. Returns \textsf{\textbf{T}} if the last move of feeb +was aborted because of timing issues. +\par\end{flushleft} +\item [{\textsf{\textbf{(last-move}\emph{~status}\textbf{)}}}] \begin{flushleft} +The feeb's previous move, or \textsf{\textbf{:dead}} if it has just reincarnated. +\par\end{flushleft} +\end{lyxlist} + +\subsubsection{Proximity and vision} + +The brain receives also information about what is near the feeb and +what the feeb sees. We note that, contrary to \emph{Planet of the Feebs}, +it is safe to change anything inside these structures, so you are +alowed to keep them stored and to modify them as you wish. + +The structure \textsf{\emph{proximity}} has the contents of the squares +near the feeb (not affected by peeking) with these fields: + +\begin{lyxlist}{00.00.0000} +\item [{\textsf{\textbf{(my-square}}\textsf{\emph{~proximity}}\textsf{\textbf{)}}}] \begin{flushleft} +Contents of the feeb's current square. +\par\end{flushleft} +\item [{\textsf{\textbf{(left-square}}\textsf{\emph{~proximity}}\textsf{\textbf{)}}}] \begin{flushleft} +Contents of the right square of the feeb. +\par\end{flushleft} +\item [{\textsf{\textbf{(right-square}}\textsf{\emph{~proximity}}\textsf{\textbf{)}}}] \begin{flushleft} +Contents of the left square of the feeb. +\par\end{flushleft} +\item [{\textsf{\textbf{(rear-square}}\textsf{\emph{~proximity}}\textsf{\textbf{)}}}] \begin{flushleft} +Contents of the square behind the feeb. +\par\end{flushleft} +\item [{The}] vector \textsf{\emph{vision}} has the contents of the squares +that are in front of the feeb. For example, +\textsf{\textbf{(aref}\emph{~vision~}0\textbf{)}} +will return the contents of the square in front of the feeb, +\textsf{\textbf{(aref}\emph{~vision~}1\textbf{)}} +will return the contents of the next square, and so on. As said before, +\textsf{\textbf{(aref}\emph{~vision~}\textbf{(line-of-sight}\emph{~status}\textbf{))}} +will be the first \textsf{\textbf{'(:rock)}} encountered. All subsequents square, like +\textsf{\textbf{(aref}\emph{~vision~}\textbf{(+}~1~\textbf{(line-of-sight}\emph{~status}\textbf{)))}}, +will be garbage and should not be used. +\end{lyxlist} +The contents of one square returned by any of these calls is either +a list of elements, a wall \textsf{\textbf{'(:rock)}} (i.e. a list with +one element, a \textsf{\textbf{:rock}}) or \textsf{\textbf{()}} if the +square is empty. Each element of the square is one of these: + +\begin{itemize} +\item \textbf{Feeb image.} One can call \textsf{\textbf{(feeb-image-p}~element\textbf{)}} +to see if element is a feeb image. +\item \textbf{Fireball image.} One can call \textsf{\textbf{(fireball-image-p}~element\textbf{)}} +to check if element is a fireball image. +\item \textsf{\textbf{:carcass}}. If there is a \textsf{\textbf{:carcass}} +in the square of the feeb (i.e. in \textsf{\textbf{(my-square}}\textsf{\emph{~proximity}}\textsf{\textbf{)}}), +the call \textsf{\textbf{:eat-carcass}} will make the feeb eat it. +\item \textsf{\textbf{:mushroom}}. Analogous to \textsf{\textbf{:carcass}}. +A mushroom appears randomly in places previously marked in the map. +\end{itemize} + +\subsubsection{Feebs and fireballs images} + +Both fireballs and feebs that are given to the brain function are +not the real ones, but just images with contents that the brain function +can access. It is allowed to keep and change its contents because they +won't be used internally. + +These are the accessors available (they read and change the fiels): + +\begin{lyxlist}{00.00.0000} +\item [{\textsf{\textbf{(feeb-image-name}~feeb-image\textbf{)}}}] \begin{flushleft} +The name of the feeb.

Also +their valid contents are limited by \textsf{\textbf{(line-of-sight}~\emph{status}\textbf{)}}, +so \textsf{\textbf{(aref}~\emph{vision-left}~\textbf{(line-of-sight}~\emph{status}\textbf{))}}, +for example, will return \textsf{\textbf{:unknown}}. + +Note that feebs that are not peeking, mushrooms and carcasses are +\emph{not} be detected by these vectors. Also, if there is a feeb +peeking to the opposite side, it won't be detected either. The +elements in \textsf{\textbf{vision-left}} and \textsf{\textbf{vision-right}} +are lists containing these elements: + +\begin{lyxlist}{00.00.0000} +\item [{\textsf{\textbf{:peek-letf}}}] This means that in that square there +is a feeb peeking to (its) left. +\item [{\textsf{\textbf{:peek-right}}}] This means that in that square +there is a feeb peeking to (its) right. +\item [{\textsf{\textbf{:rock}}}] This square is just a wall. In this case, +this is the only element in the square. +\end{lyxlist} + +\subsection{Extra functions provided} + +Before making the brain of your feeb, you might want to take a look +at the Extra functions that are available at the end of the feebs.lisp +file. The only thing you need so you can use them is to see their +code and know what they do. + + +\subsection{Changing the map layout} + +It is possible to change the layout of the map by calling +\textsf{\textbf{(change-layout}~new-layout\textbf{)}}. +There are a few predefined mazes that are in variables \textsf{\textbf{{*}maze-0{*}}} +(which is set by default) throw \textsf{\textbf{{*}maze-5{*}}}. +In a layout, `X' represents a wall, `e' represents a feeb entry point +(there will be as many entry points as feebs in the maze at the same time), +`m' represents a mushroom site and ` ' is a blank space. + +If you want to create a new map, you can start by an empty template +of any size that is provided by \textsf{\textbf{(make-template}~x-size~y-size\textbf{)}}, +or you can get a reandom map calling +\textsf{\textbf{(generate-maze}~x-size~y-size~\textbf{:density}~density\textbf{)}} +The density is a number, recomended to be between 0.25 and 0.45, +which tells the portion of the maze should be blank spaces. +The function quits after a while if it doesn't meet this portion. See +its documentation for more details and options. + + +\subsection{Graphics} + +With this version of the game, it's possible to choose the graphics +of a feeb when creating it, so your feeb will be more personalized. + +The graphic of a feeb is defined by an image file, which should have +three colunms by eight lines of pictures of the same size. The four +first lines must be the animations of the feeb walking up, left, down +and right, respectively. The next four lines must be the pictures +of the feeb flaming up, left, down and right, respectively. To see +an example, see {}``default-feeb.png''. + +After creating the image file, you must call \textsf{\textbf{(create-graphics}}\textsf{~path-to-image-file}\textsf{\textbf{)}}. +If you now how to work with sdl surfaces in lispbuilder, you may use +the function with a surface instead of a image file; or you can call +\textsf{\textbf{(create-graphics}~path-to-image-file~nil\textbf{)}} +if the surface should not be freed after the call. The result must +be the third argument given to define-feeb. + + +\subsection{Starting the game} + +The game loop is started by calling \textsf{\textbf{(simple-play)}}. + + + +\section{Contests} + +I sugest that you see this chapter only after you have created at +least a basic brain feeb, which is better than the (simple) provided +brain, or if you want to participate of a contest or a game with +your friends. + + +\subsection{\label{sub:Map}Map} + +It is possible to get the maze map during the game, but with only +the corridors. Note that the function that gets the map is purposely +a little slow, so, invoking it too many times in a contest that uses +timing atributes is not a good idea; anyway, it is possible to invoke +this function before defining the feeb, and store its value somewhere. +Also note that the map returned does not have any information about +what is really in the maze, but only the possible ways. + +To get the map, one can call \textsf{\textbf{(get-maze-map)}}. This +function will return \textsf{\textbf{nil}} if parameter +\textsf{\textbf{'may-get-maze-map-p}} is also \textsf{\textbf{nil}}. +Otherwise, the map returned is an array, so that calling +\textsf{\textbf{(aref}~map~x~y\textbf{)}} will get the contents +in the position (x,y) (like euclidean but inverting the y axis). +The contents of a cell could be one of these: + +\begin{lyxlist}{00.00.0000} +\item [{\textsf{\textbf{:mushroom-place}}}] A mushroom patch, i.e. when +a mushroom is reincarnate, it could reincarnate here. +\item [{\textsf{\textbf{:feeb-entry-place}}}] A feeb entry, i.e. if a carcass +rots a feeb can appear here. +\item [{\textsf{\textbf{:rock}}}] A wall. Feebs cannot come to this place. +\item [{\textsf{\textbf{nil}}}] An {}``empty'' place, i.e. neither of +the previous. +\end{lyxlist} + +This map can safelly be used since \textsf{\textbf{(get-maze-map)}} makes +a new copy every time it is called. + +\subsection{Timing} + +There are also some timing atributes that can be given to the game. +The more time the feeb takes make a decision, greater is the probability +of its command to be aborted. + +To make this available, someone must set these parameters: + +\begin{lyxlist}{00.00.0000} +\item [{\textsf{\textbf{'slow-feeb-noop-switch}}}] If is non-nil, +there is a possibility that the move of a feeb is aborted according +to its function time. +\item [{\textsf{\textbf{'slow-feeb-noop-factor}}}] The probability +of the feeb to abort will be this factor times the amount of time +the feeb takes to have a decision, divided by the total time taken +by all the feebs in the current turn or divided by a reference time. +\item [{\textsf{\textbf{'reference-time}}}] Time taken by reference +if non-nil. +\item [{\textsf{\textbf{'points-for-slow-down}}}] Points earned when +a feeb's move is aborted due to slowness. +\end{lyxlist} + +\subsection{Sense of location} + +Some accessors related to position and orientation of the feeb can +be turned off. + +These are the parameters: + +\begin{lyxlist}{00.00.0000} +\item [{\textsf{\textbf{'sense-location-p}}}] If nil, +\textsf{\textbf{x-position}} and \textsf{\textbf{y-position}} +will return nil when someone tries to invoke it. +Otherwise return the position. +\end{lyxlist} + +\subsection{Changing the rules} + +To change the rules of the contest, they must be changed before the +feebs are defined, because in a feeb definition it could use the values +of the variables to make a global strategy. + +All the parameters, values and documentation that can be listed using +\textsf{\textbf{(list-parameter-settings)}} can be changed using +\textsf{\textbf{(change-feeb-parm name value)}}, which is deactivated +during the game. Also, they all have documentation about themselves, so feel free to use +\textsf{\textbf{(documentation~}}\textsf{'parameter~'feeb-parm}\textsf{\textbf{)}} +and see what each parameter does. Documentation is available to external +functions as well. + + +\section{Reference} + +\begin{quote} +Fahlman, S.
