DOORS

doorobjlist[] holds most of the information for the doors
|
|
|
|
doorposition[] holds the amount the door is open, ranging from 0 to 0xffff
|
|
this is directly accessed by AsmRefresh during rendering
|
|
|
|
The number of doors is limited to 64 because a spot in tilemap holds the
|
|
door number in the low 6 bits, with the high bit meaning a door center
|
|
and bit 6 meaning a door side tile
|
|
|
|
Open doors conect two areas, so sounds will travel between them and sight
|
|
will be checked when the player is in a connected area.
|
|
|
|
Areaconnect is incremented/decremented by each door. If >0 they connect
|
|
|
|
Every time a door opens or closes the areabyplayer matrix gets recalculated.
|
|
An area is true if it connects with the player's current spor.
