Okay I havenít finished my remake of Joust yet, nor did I want to wait until the last week of the month to get an article out. Instead, I offer you Monster Maker as Juneís monthly program. Itís pretty straight forward and anti-climatic against the power of todayís programs. Once you load it, enter in five numbers and type your monsterís name. Thatís it. The program will then display a nicely formatted monster description based on your input.
If you couldnít tell, I wrote Monster Maker during my D&D days. I fancied myself a DM (dungeon master) and spent a lot of time drafting out maps, writing campaigns, and creating new monsters. It shouldnít be surprising that my work often spilled into my programming. Unfortunately, this attempt wasnít very advanced. The monster created is pretty static and running it more than once yields minor changes.
Monster Maker is actually a ZX81 version of a program I drafted for the schoolsí computer. I hadnít learned random numbers or flow control yet when I first penned it so the program is pretty basic. It uses mostly
AT. I even used some functions like
ABS to remove the sign should a negative number be returned. I also used DIM to create a number array, a common function even on old computers. There are a lot of good programming concepts here, just not enough.
If this had been an exercise, by the way it wasnít, I could have presented a few more challenges to the programmer as he or she learned more BASIC commands. Here are some of my ideas should you wish to attempt them.
- Eliminated the need to input numbers.
- Using flow controls, change the shape and color of the monster.
- The statistics arenít very interesting, add more variability in them. (Extra credit, find a D&D book and try to match them based on the monsterís level.)
- Create a random name generator to drop the need to query the user. (Check here for inspiration.)
Iím sure you can think of a few more ways to make this program even more interesting. You could even attempt to use this monster generation routine in a battle game. See, even a simple program can be a jumping point for something bigger.
My programs, fortunately, did get better and much more interesting. However, visiting these old programs remind me of the wonder I had when I first learned about computers. But even a computer as simple as the ZX81 can do some pretty amazing things. As archaic as these programs may seem, they have the roots of many of the amazing programs you use today. Monster Maker was root for me, one that grew into a life long career.
If you want to run this program on your Android phone or tablet you can download a compressed copy of the program to your device. Youíll need to save the .p version of the program to your device to allow Zed Ex (Beta) to run it.
