The following are explanations of things that some people seem to be confused about. There are no new requirements here; the intent is to clarify the existing requirements.

Gorgo

• You are not Gorgo!

  Gorgo is a Neandertal (cave man) who wanders around the game doing random things, and mostly gets in your way. When, for example, Gorgo takes the key, you can't take the key; if you want it, you have to wait for him to drop it again.

  Unless you want to change that part of the program (which would be fine with me), there isn't much you can do about Gorgo.

• The assignment says, "Fix the look command so that look Gorgo works." The problem is that look Gorgo always produces "I don't see it here." regardless of whether Gorgo is in the room with you or not. You should be able to look at Gorgo and get a description of some sort if he is present, and not if he is in some other room. This is a bit of a challenge because Gorgo is not (and should not be) a Thing.

Commands

• The assignment says, "Be sure to list your commands with the others when the user types help." This implies that you need to add new commands, not just new versions of the use command. New commands might be, for example, open box, shoot gun, escape, teleport Room, eat, eat food, etc. If it makes sense to use the verb use, it would be a good idea (though not required) to overload it: use gun, but probably not use box.
  
  
• All commands are one or two words: either verb or verb object. For example, escape would mean that you, the player, escape from something; look gun would mean that you, the player, look at the gun. While look at the gun would be better English, my parser isn't that sophisticated.
  
  
• The assignment says "Do not use lock or unlock--I've already written the code for those." That is, your object should do something other than (or in addition to) creating/removing paths between rooms. You need to add commands that require writing at least a little bit of original code.
  
  
• Your commands should have reasonable conditions. For example, you can't use the key unless you are holding it and your are somewhere that there is something to lock. You shouldn't be able to shoot a gun unless you are holding it.

Things

• You need to add two objects to the game. These objects are probably associated with your new commands, but that isn't necessary. For example, if you add a gun object, you probably want a shoot gun command (or maybe a shoot command). But you could equally well add, say, a run command that takes you to some randomly chosen adjacent room, and this would have nothing to do with any particular object.
  
  
• If you add your things correctly (as subclasses of Thing), you will automatically get the correct behavior for take, drop, and inventory, and reasonable default behavior (which you should probably override) for look and use. If this doesn't happen, you've done something wrong.

Rooms

• You can add new rooms as subclasses of Room, but this only makes sense if there is some new behavior you want to add for a room. In general, though, you should read my code and create your rooms the same way I did.
  
  
• Please add descriptions of your new rooms.

String Comparisons

If you have two Strings you want to compare, say, string1 and string2, you should say string1.equals(string2) rather than string1==string2. If one of the strings might possibly be null, use it as the parameter; for example, "key".equals(thing) is better than thing.equals("key"). This will avoid some problems which we will talk about in class when we get to the lecture on characters and strings.
