25534: Determine ERIC's y-coordinate

Used by the routines at 25944 and 32000. Returns with D holding ERIC's y-coordinate if he has his feet on the floor. Otherwise returns with D=3, 10, 14 or 17, indicating the floor that ERIC is directly above.
25534 | LD DE,(53761) | Get ERIC's coordinates in DE
25538 | LD A,(32763) | Copy ERIC's status flags from 32763 to A
25541 | RRCA | Is ERIC jumping?
25542 | JR C,25551 | Jump if so
25544 | RRCA | Does ERIC have his feet on the floor?
25545 | RET NC | Return if so (with D holding ERIC's y-coordinate)
25546 | LD A,(32749) | Copy ERIC's other status flags from 32749 to A
25549 | AND 6 | Set the zero flag unless bit 1 (ERIC is standing on a plant) or bit 2 (ERIC's stepping off a plant or the stage) is set
25551 | JP 28085 | Determine which floor ERIC's closest to
