ec1eb7cc0e Directly control the Ensoniq sound chip by writing to its registers to play sounds rather than using the free form synthesizer functions in the sound toolbox. 2020-12-17 00:35:56 -05:00

d201f80c3b Move the sound code into a gameSound.s file. This is the first step towards going around the sound toolset for playing sounds. 2020-12-16 12:00:56 -05:00

42585898a4 Rename tileData.pl to genData.pl because we are generating more than just tile data now. 2020-12-08 00:28:04 -05:00

73458254e5 Add an acknowledgements file and fill in some information but I need to go through and make sure more people are recognized for their support. Add some raw sounds and include them as resources in the binary. 2020-12-08 00:23:42 -05:00

fd40c12d31 Explode a bug when it crashes into the player. When the last segment collides with the player, go onto the next level. 2020-11-18 23:36:01 -05:00

520aaa5a34 Add collision detection for all of the bug types. Remove the debug code for shooting bugs. It is almost a functional game now! 2020-11-17 22:53:30 -05:00

4e6bad0ae7 Start adding the code for supporting shooting. 2020-11-16 00:14:08 -05:00

edcddc0bd8 This build has the player moving in X and Y directions and with cleaner handling of the dirty tile to remove the inefficiencies. The good news is that there is no longer any performance problem at 2.8 MHz now that the inefficient dirty tile handling has been removed. The bad news is that they player leaves garbage behind indicating some kind of problem with dirty tile marking. But it is close. 2020-11-05 00:21:46 -05:00

bb66ef4b03 Replace the C code which built tables at game launch time with a script which generates these tables at build time. This reduces the start time of the application and saves code space and is a necessary step before adding some new tables to handle the mouse efficiently. 2020-11-04 22:48:18 -05:00

4e500c6f38 Start adding some mouse code and display a player on the bottom row of tiles only for now. No collision detection hooked up and it is terribly inefficient but it seems to work. 2020-10-28 23:46:32 -04:00

62fcc82790 Add the code to shoot mushrooms and hook up a debug routine to shoot random mushrooms. 2020-10-26 23:26:12 -04:00

9a34532d77 Implement the code to add spiders to the game. From my testing, it looks like 2 seconds after a spider leaves the game (either shot or off the screen), another one is added. Also, once the score is about 5000, the spiders added will be fast. The only spider behaviour I know of which is so far not implemented is as the player reaches higher levels, the spider constrains itself closer and closer to the bottom of the screen. 2020-10-22 00:00:16 -04:00

a1b4013e1c Hook up the score. Shooting fleas, spiders, scorpions or segments will increase the score. We track the score in two ways. One is just as a 32-bit unsigned integer for doing numeric comparisons on the score (say to the high score list to be implemented in the future) and secondly as a series of numeric digits displayed in a tile. Both are updated. 2020-10-13 23:24:15 -04:00

b85000b4ed Start adding the infrastructure for levels and score. 2020-10-13 00:09:37 -04:00

c4902f486b Add some global data to have a bit mask of tiles which contain a centipede segment. This will allow the update code to figure out if centipede segments are colliding and if so, change direction. Still need to write some codegen for this global constant data rather than building it at runtime in C. 2020-09-20 22:22:58 -04:00

7d7afc908d Use macros to reduce the copy/pasted code for marking tiles as dirty. Rough out the support for body and head segments. 2020-07-30 23:34:48 -04:00
Jeremy Rand
4f74d630b9 Start coding support for the spider. Also, try to show the performance of the main game loop in the border colour. 2020-07-23 23:41:12 -04:00

c614164c14 Add code to get scorpions animating to the left. Lots of cleanup, adding a global data section that also has important global constants. 2020-07-21 21:47:50 -04:00

1ccdb1d0b6 Start to get scorpion support into the game. 2020-07-20 23:04:27 -04:00

88ea840e23 Update the flea sprite as it drops. Add random routines. Thanks to John Brooks for those. Use the random routines to pick a column for the flea to drop from. Also, randomly leave behind a mushroom as it falls. 2020-07-19 15:15:45 -04:00

0336c692c4 Add some code to support animating fleas in the game. 2020-07-18 22:11:20 -04:00

a718c8caef Lots of general sprite cleanup. Add sprites for the ship and the shots and include collision detection in those routines. I think all of the drawing code is done now, maybe? 2020-07-09 22:55:08 -04:00

7f33c3d400 Create all of the left facing head segment sprites. 2020-07-04 02:45:53 -04:00

598934446b Finish the spider sprites and the explosion sprites. Remove "and" masking from the spider and scorpion sprites because they will be drawn first and will not overlap with anything on the foreground. Split the sprite.s file into a series of smaller files for each type of sprite. Add a file to describe the overall plan for the design of the sprites. 2020-07-02 22:57:52 -04:00

a9810ecb75 Well, it launches, clears the screen, waits for a key and then quits. But it is a start. 2020-06-10 23:51:53 -04:00
