Used by the routine at 25581. Checks for a closed door in the character's path and makes him open it if he's an adult.
Input
H | Character number (183-209)
28814 | CALL 28767 | Check for closed doors in the character's path
28817 | JP NC,25012 | Update the SRB for the character's current animatory state and location if no doors need opening
28820 | LD A,H | A=character number
28821 | SUB 200 | Are we dealing with a teacher or ALBERT (i.e. someone who can open doors)?
28823 | CP 6
28825 | JR C,28833 | Jump if so
28827 | CALL 25012 | Update the SRB for the character's current animatory state and location
28830 | XOR 128 | Characters who can't open doors have bit 7 of their animatory state flipped (i.e. they are turned around)
28832 | RET | Return to place the character midstride
The character we're dealing with is confronted by a closed door and is able to open it.
28833 | POP DE | Drop the return address; we will handle updating the SRB and setting the character's new animatory state here instead
This entry point is used by the routine at 25944.
28834 | LD L,19 | Place the identifier of the closed door (see 28767) into byte 19 of the character's buffer
28836 | LD (HL),C
28837 | INC L | L=20
28838 | LD (HL),1 | Signal: open the door
This entry point is used by the routines at 29052 and 62572.
28840 | LD L,18 | Place the address of the uninterruptible subcommand routine at 28855 into bytes 17 and 18 of the character's buffer
28842 | LD (HL),112
28844 | DEC L
28845 | LD (HL),183
28847 | CALL 25012 | Update the SRB for the character's current animatory state and location
28850 | OR 7 | A=animatory state of the character with his arm up (to open the door)
28852 | JP 24880 | Update the character's animatory state and update the SRB
