  edu.gatech.cs2335.lemmings.file.LevelReader

public class LevelReader

extends java.lang.Object

Allows us to read level data, maps and other nice stuff. The string passed in to any of the "load" methods is basically the id of the level. The loader then tests if there is a directory with the same name in the levels list. If there is one, then it loads the level from it. If there is no such directory, then is appends a .lmf extension to it and checks wether there is a file with that name. If there is, it extracts the file and then loads the level from that. If there is no such file, then the loading fails and null is returned.
