384a9ea233 Make more globals per player and index into them with the player number at game time. 2021-01-10 23:17:05 -05:00

8963a9d76c I believe I have fixed the invisible mushroom bug. I have inspected all of the code which sets a tileType to something that didn't mark the tile as dirty. I believe the problem occurred because the code in update which placed/changed mushrooms assumed that the draw code which then mark the tile as dirty because the bug which caused the change which dirty that tile. But that is an assumption. If the bug is shot, perhaps the draw routine will not mark the tile dirty. So, now the tile is always marked dirty right at the point where the mushroom is placed. I believe this will fix the problem but more play testing is required to confirm I don't see it anymore. 2020-12-26 15:26:19 -05:00

b432cf654b Implement stereo sound. Sounds now come from the left or the right speaker depending on where the sound is coming from on the screen as much as possible. 2020-12-22 23:40:21 -05:00

d962e98368 Add the flea sound. 2020-12-22 01:00:10 -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

0136579125 Disassociate sound resources from the generators they are connected with. Use multiple generators to play multiple shot sounds at the same time. It sounds weird but it kind of works. 2020-12-10 21:55:13 -05:00

bae931aaa6 Add sounds for shooting, killing bugs, dying and resetting mushrooms after death. The shoot sound isn't great because it doesn't restart when rapid fire is happening but this is a start. 2020-12-10 00:45:48 -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

2abb57b1a5 Add the code for detecting player collisions, exploding the player, decrementing the number of lives and maybe ending the game. 2020-11-11 23:51:09 -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

0dd8222611 Add the code to handle restricting the spider to lower and lower rows as the score goes up. This is the final bit of game logic necessary for the bugs in the game I think. 2020-10-26 22:32:46 -04:00

5a08aefab5 Fix the code for setting the starting flea speed based on the score threshold. 2020-10-25 23:19:31 -04:00

96a6b6f51f Implement the code to add the flea at the right time. This includes tracking the score in multiples of 20,000 and adjusting the number of mushrooms required in the infield before a flea will appear. Simplify the other score based thresholds which are based on multiples of 20,000 to use this test. Add debug which allows me to add 20,000 to the score whenever I want so I can test these thresholds more easily. 2020-10-25 23:11:11 -04:00

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

92c02ded0f Simplify the handling of the dirty tiles to just store the dirty word and not keep the array of dirty tile offsets. Have the flea use game and non-game dirty tiles to fix the problem with LHS tiles being marked dirty all the time. 2020-09-04 01:55:38 -04:00

22a22d3533 Change the code to race the beam down the screen, redrawing the dirty game rows as it goes. 2020-09-04 00:17:19 -04:00
Jeremy Rand
b07221c363 Change from an array of structs to a series of individual arrays for the tile information. This makes it easier to index into the arrays because the tile number * 2 is the offset, rather than tile number * 16. 2020-09-02 00:15:53 -04:00

3a63b2ef1b Add code to support marking dirty tiles under head and body segments. 2020-08-27 22:36:04 -04:00
Jeremy Rand
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

2b45813cbb Increase the chance that a flea produces a mushroom. 2020-07-28 15:44:55 -04:00

883d882d0e Provide an API to set the default speed of a flea or a scorpion. This will allow the speed to be changed for different levels in the game. Need to add this API for spiders also. 2020-07-27 22:27:18 -04:00

3ad311dca6 Add support for shooting the spider and displaying a score. 2020-07-27 14:22:34 -04:00

b3da2023e4 Get the scorpion moving to the right and to the left and poisoning the mushrooms. Still need to handle exploding the scorpion and double speed scorpions. 2020-07-22 00:06:01 -04:00

44cb944f22 More general cleanup and get rid of more magic numbers. 2020-07-21 22:30:05 -04:00
Jeremy Rand
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

b813253c83 Add support for shooting fleas. When a flea is shot once, it accelerates its drop to the bottom. On the second shot, it explodes. 2020-07-20 00:05:18 -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
