29052: Make a character open or close a door
Used by command lists 22, 24, 26, 28, 76 and 78. This routine works on two parameters. First the door identifier:
ID Door Command lists
8 Boys' skool door 76, 78
16 Skool gate 76, 78
32 Drinks cabinet door 22, 24, 26, 28
And then the action identifier:
0 Close it
1 Open it
Input
H 204 (MISS TAKE) or 205 (ALBERT)
29052 LD L,3 Replace the address of this routine in bytes 3 and 4 of the character's buffer with 29061 (below)
29054 LD (HL),133
29056 LD L,19 Copy the door identifier and open/close parameter from the command list into bytes 19 and 20 of the character's buffer
29058 CALL 25188
29061 LD L,19
29063 LD A,(HL) A=door identifier
29064 CP 8 Is it the boys' skool door?
29066 JR NZ,29101 Jump if not
29068 LD A,(54017) A=x-coordinate of the bike
29071 CP 94 Is the bike in the boys' skool?
29073 JR C,29087 Jump if so
29075 LD DE,4448 (E,D)=(96,17)
This entry point is used by the routine at 29101 with (E,D)=(136,17):
29078 CP E Set the carry flag if the bike is blocking the way
29079 LD A,(54016) A=bike's animatory state
29082 CALL C,26496 Move the bike to the location in DE if it's blocking the boys' skool door or the skool gate
29085 LD H,205 205=ALBERT
This entry point is used by the routine at 29101.
29087 LD L,4 Remove the address of this routine from bytes 3 and 4 of the character's buffer
29089 LD (HL),0
29091 JP 28840 Open or close the door
