Implementation details:
|
|
+ stoppers have special $10 line behind them
|
|
has to be special so climbers can't treat it as wall
|
|
and climb
|
|
+ bridge is solid $FF color. Allow things to walk through this,
|
|
so shouldn't allow backgrounds to have this pattern
|
|
|
|
|
|
Plan for future scrolling:
|
|
+ Foreground drawn with a tilemap
|
|
Write program to pick optimal tiles
|
|
5 wide screen = ? in size
|
|
Scroll the tilemap
|
|
+ Actual collision detection happens in offscreen buffer
|
|
Each pixel equivalent is one 7-pixel chunk wide
|
|
Should be small enough
|
|
Physics engine happens entirely on that
|
|
|
|
|
|
|
|
Heights for detection:
|
|
Walking lemming = 10 high
|
|
Floating lemming = 16 high
|
|
|
|
Detect ground (walking) = y+10?
|
|
Detect in ground (need to bump up) = ?
|
|
Height we detect wall collision = ?
|
|
|
|
|
|
|
|
|
|
|
|
LEMM: 23782 (original v0.01)
|
|
|
|
|
|
Plan:
|
|
$000 = zero page
|
|
$100 = stack
|
|
$300 = disk lookup tables
|
|
$400-$700 = text page 1
|
|
$800-$b00 = hgr lookup tables
|
|
$c00-$f00 = particle effects?
|
|
$1000-$1100 = disk code
|
|
$1200-$1f00 = common routines
|
|
|
|
HGR PAGE1 = $2000
|
|
HGR PAGE2 = $4000
|
|
|
|
LEMM load at $6000
|
|
|
|
LEVELs load at $A000
|
|
|
|
SOUND/MUSIC data in language card at $D000
|
|
|
|
|
|
level data
|
|
number of lemmings
|
|
number needed to win (percent? percent is hard)
|
|
lemming_start_x
|
|
lemming_start_y
|
|
lemming_start_direction
|
|
location of entrance door
|
|
entrace door type
|
|
location of exit door
|
|
number of each job type
|
|
release speed
