29696: Calculate appropriate coordinates for a message box
Used by the routines at 29716, 29896 and 62668. Returns with the coordinates of the messenger's head in DE.
Input
H Messenger's character number (200-205)
29696 LD L,1 Point HL at byte 1 of the character's buffer
29698 LD E,(HL) E=character's x-coordinate
29699 INC E E=x-coordinate of the character's head
29700 DEC L L=0
29701 LD A,(HL) A=character's animatory state
29702 AND 7 Keep only bits 0-2
29704 CP 6 Set the zero flag if the character is sitting on the floor
29706 LD A,0 The y-coordinate offset should be 0 if the character is standing
29708 JR NZ,29711 Jump if character is standing
29710 INC A A=1 (one level lower if the character is sitting on the floor)
29711 LD L,2 Point HL at byte 2 of the character's buffer
29713 ADD A,(HL) Add the character's y-coordinate and the offset
29714 LD D,A D=y-coordinate of the character's head
29715 RET
