Remember way back in 1.02 when we generated a whole world full of maps and added the ability to move between them? Let’s add that functionality back in. But now, we’ll put it behind our new user interface that we built using Curses.
The PC can now use the movement keys to move into a gate. Doing this does not leave the PC standing in the gate; instead, it places the PC in the in the road square directly abeam of the gate in the neighboring map. For example, if the west gate is at (0,10) in map (0,0), moving west into (0,10) will place the PC at (78,10) in map (-1,0).
NPCs cannot move into gates.
NPCs and their respective turn queues should be maintained across movement through gates. To achieve this, you’ll probably want a turn queue per map. Time does not (need to1) pass in a map where the PC is not present.
Additionally, implement fly, as per 1.02, but using the curses interface you built last week. The command ’f’ indicates that the player wants to fly. The interface will then need to read X and Y coordinates. Placement within the destination map is at your discretion (on the road is probably a good idea). Turn queues and NPC positions should also be maintained while flying.
We’ll be converting (porting) our entire game into C++ this week, as well. You’ll need to rename all of your C files with a .cpp extension (if using my makefile, do a make clobber before renaming). You’ll also need to update your makefile. If you’re using one of my code drops (or if you’ve taken my makefile into your project), there is already automatic support to compile C++ code; however, you will need to change the link line to link with the C++ compiler (try to figure this out on your own).
The major structs in your game should be changed to classes; this includes the map and the character structures. There are no requirements about access to members (public, private, etc.); you decide what you think is best. My code uses a pseudo-object-oriented design of the character t, with sub-types pc t and npc t. If you are using my code, you should change these so that they use C++ class inheritance (pc and npc should inherit from character2). If you’re not using my code, but you have a similar design, you should also use inheritance3.
You do not have to do anything with heap.h and heap.c. These already include the necessary syntax to make them play nice with C++ and may remain as C files.
