Apple ][ Graphic Adventure Part V

Now that my memory issues are seemingly under control, let's take a look at my modifications to the parser. Normally, in these types of graphical adventures the player enters two words in the form of VERB OBJECT. My interface limits the number of verb choices and allows the player to enter a verb with a single keystroke.

Apple ][ Graphic Adventure Part IV

Previously I discussed the overall structure of my soon-to-be hit adventure game. Well, last night was a milestone. I managed to write an Applesoft program so epic that it overwrote the high-resolution graphics page. Compared to other programs I have seen, mine isn't that huge. Around 250 lines isn't that huge, right? Transylvania clocks in at 464 lines.

Apple ][ Graphic Adventure Part III

The previous post in this series explained how to get Graphics Magician images to display from Applesoft. Now, I'd like to go over the structure of the program listed in Write your Own Adventure Programs. The bulk of the program listing consists of the game data including objects, room descriptions, verbs and state flags. Most of the remaining code is comprised of a series of conditions that check how the player's actions affect the objects in the game world.

Apple ][ Graphic Adventure Part I

Having recently played the Apple ][ game Transylvania and its sequel, I was inspired to mess with the art program which those games used. The Graphics Magician was a huge hit for Penguin Software, but I never actually had a chance to use it when we had an Apple ][. I just remember it being advertised in every computer magazine I had.

Apple ][ Assembly Language Programming

The past few weeks I have been diving into the world of assembly language programming on the Apple ][ computer. My interest in the topic stems from the recent book release of a compilation of articles on assembly language programming called Assembly Lines: The Complete Book. The articles were written by Roger Wagner and originally published in Softalk magazine back in the early eighties. This edition was edited by Chris Torrence and is available for download and purchase from a number of locations.

Now, I am pretty familiar with Applesoft Basic programming, but I was always in awe of commercially released software on the Apple ][ that ran so fast, had fancy hi-res graphics and used sounds other than the system beep. What was the secret of these mythical programs that required you to type "BRUN" in order to get them to load? The secret was machine language.

My First Foray into SASS

As I mentioned a few posts ago, this site has received a major theme overhaul. Aside from a couple form element styles, this change was mostly structural and behind-the-scenes. The new theme is my first foray into using the SASS CSS preprocessing language. Let me tell you, it was a revelation. SASS allows you to write CSS using a super-clean tabbed coding style and (finally) allows the use variables and expressions in styles.

Haunted House Text Adventure

Type 'HELP' for a list of verbs.

Back in the late 80s, I learned much about computer programming from this book: Write Your Own Adventure Programs For Your Microcomputer. This is the same book that I used as a guide when creating Malfunction for my Apple IIgs back in 1988.

"Dippy Golf" - Another Apple ][ Game I Wrote as a Kid

After posting Malfunction, my text adventure game for the Apple ][, I have been spending a whole bunch of time tinkering with my old Apple ][ software creations. Another one of my better creations was a golf game that I titled, Dippy Golf. This game featured nine holes which were loaded in from external graphics files and, even more impressive, was the use of audio samples of my voice! The game worked but still felt somewhat unfinished, so I decided to complete the game and post it here on the Pages of Fun!

My Apple ][ Masterpiece, "Malfunction"

(Okay, Masterpiece should probably be in quotes too!) I have been on a bit of a retro computing kick this evening. I have been playing around with AppleWin, which is the best Apple ][ emulator for Windows that I know of. I played a little bit of the original Castle Wolfenstein and then decided to fire up my trusty Apple ][gs and port some of my old Applesoft programs to PC.
