the design of elements in PAC MAN scene such as maps characters items and winning conditions It is designed especially for those who have wished to be a God in the world of Pac Man PaCaml helps recall a generations of 1980 s of the best of their childhood memories 1 1Background PAC MAN is an arcade game immensely popular since its original release and is considered as an icon of 1980 s popular culture 1 It has made a great impact on a generation of people and is still appealing to the public for today 2 However the game scenes of each stage the size of the map winning condition and the number of ghosts etc in PAC MAN is all pre designed and players are unable to create or change them It could be a great fun if the players can design a PAC MAN based on their own favorite Therefore we introduce PaCaml a PAC MAN game design language which enables users to create their favorite scenes and design whatever they like to make PAC MAN more interesting 1 2Description The language PaCaml PAC MAN Ocaml is developed using Ocaml language It is text based and java like but has its own primitives The language has a main function like C and each statement ends with a semicolon The basic idea and rules in PAC MAN will not be changed However the language allows users to design mazes number and distribution of eating dots number and speed of the ghosts location of the power pellets figure of each character etc Users can also design the condition of scoring and set the winning condition using the language 1 1 3Features Simple We aim to design a language which can be fast and easily learned by users As most of programmers today have dealt with Java we design PaCaml and make it very similar to Java in syntax and expressions We omit some data types which are not necessary in PaCaml such as any floating point related types boolean etc We also add some game related functions like setMap setPlayer which make the language easy to program Object oriented PaCaml inherits the technique of object oriented design from Java which focuses on the data objects and on the interfaces to it Statically scoped PaCaml is statically scoped which means that the environment in PaCaml which is extended and becomes current when a procedure is called is the environment in which the procedure was created Applicative ordered PaCaml uses applicative order during the evaluation Robust As we have said the programmer will be the God in the world of Pac Man which means they can design the Pac Man as they wish Users are able to design the strategy of the ghosts color of characters etc Interesting Our goal is to make Pac Man programming as interesting as possible Unlike other languages which might be tedious during programming PaCaml is designed to be friendly interacted with programmers 1 4A Quick Look at PaCaml Code int main create a barrier a ghost and add them to the map point p player pacman 2 item bar item ghost add a barrier p getAvailablePoint bar i type BARRIER
