|
A warlock can appear in the room:
No warlock appears on level 8 (Chambers of Chaos). On level 9 (High Temple of Chaos), DEMONS materialize in rooms instead of warlocks.
|
||||
| 54865 | LD A,(60105) | Get the current level text number (1-9) - calculated from lookup table at 50852 | ||
| 54868 | LD B,A | Store in B register | ||
|
There are only 7 warlocks, so we need to do something for levels 8 and 9
|
||||
| 54869 | CP 8 | Are we in the Chambers of Chaos (level 8)? | ||
| 54871 | JP Z,54991 | If so there's no warlock on this level - jump to the end of this check routine | ||
| 54874 | CP 9 | Are we in the High Temple of Chaos (level 9)? | ||
| 54876 | JR Z,54948 | If so, jump out and generate a DEMON instead of a WARLOCK | ||
| 54878 | LD A,(60074) | Game cycle timer | ||
| 54881 | AND 63 | Check bits 0-5 (values = 0-63) | ||
| 54883 | JP NZ,54991 | |||
|
Every 64 game cycles, reduce the timer counter for a warlock appearing in the room
|
||||
| 54886 | LD A,(60340) | Get warlock appearance timer | ||
| 54889 | DEC A | Decrement it | ||
| 54890 | LD (60340),A | ...and re-store | ||
| 54893 | LD C,A | |||
| 54894 | CALL 56070 | Run pseudo-random number generator to produce a random number (returned in A register) | ||
| 54897 | CP C | Compare it against the warlock appearance timer | ||
| 54898 | JR C,54991 | If random number < warlock timer, jump out here | ||
| 54900 | LD A,(60333) | Random number > warlock timer. Get byte 6 of warlock data set | ||
| 54903 | CP 0 | |||
| 54905 | JR NZ,54991 | If this byte isn't 0, there's already a warlock so we can jump out at this point | ||
