Lady Bug

BTW did you know that at the start of the game the tune plays longer with a bit more variation if you don't start shooting aliens immediately as the alien dying sound effect cuts the music short

I did something silly with the editor, I created a maze with only 1 dot that is right under ladybugs starting position and loaded this into all 3 maze slots

Now when the level starts ladybug will automatically collect the dot under her which ends the level
The level will then advance to the next and continue do this forever

When I originally wrote ladybug it was a single maze game like the arcade game where the central enemy box had a single upwards facing exit

Later I added the maze editor to allow players to create/edit many mazes on disk and select any 3 to play in game, this led to the possibility of the enemy central box having exit(s) in other directions or even none at all !

The game was originally hard coded to assume that there was only the upward facing exit so in this build I have fixed the .enemyRelease function in ladybug.asm to check for available exits and chose one at random, if none exist then the enemy is left inside the box and isn't released

I just wondered what would happen if you

1) create a maze and save it
2) press break and *delete it
3) boot the disk and go back to the editor

well it doesn't like it ! maybe I should fix this ?
the editor is extremely low of free memory so I'm not sure it will be possible to add the extra code required

a work-around if this ever happens is to boot the disk, choose option 'R' and reset the maps to default
after this the editor will load correctly and you'll be able to load and edit your custom maps again

I had a thought about this and I think the solution would be to do the file exists check in boot.bas which can replace a missing file name with a default map name to prevent this editor glitch

i'll add that tonight

Build 003388

Added a test in boot.bas to check if the files named in _Maps actually exist on the disk, any files that are not found will have its filename in _Maps replaced with the default file name for that slot _Map1 _Map2 _Map3

This prevents the map editor going crazy if a map file was renamed or deleted from the disk but still referenced in the _Maps file

Build 003392

I noticed that the changes to boot.bas has had an effect on reset.bas for some reason, when choosing the R option from the menu I saw that the screen kind of glitched a little so I have fixed this by changing the way the screen is cleared

Also in .enemySpawn (ladybug.asm) there were two loops to check if the enemy box was empty and if there was an available enemy to spawn into the box, I have combined these two loops into one saving 7 bytes
