This checks that the hero is within the roll call bounds. hero_map_position_x must be in ($72..$7C) and hero_map_position_y must be in ($6A..$72). If not, then the bell is sounded and the "MISSED ROLL CALL" message is queued. Otherwise all visible characters are made to face bottom left.

Is the hero within the roll call area bounds?
|
||||
| event_roll_call | EF9A | LD DE,$727C | Load DE with the X coordinates of the roll call area ($72..$7C) | |
| EF9D | LD HL,$81B8 | Point HL at global map position (hero) | ||
| EFA0 | LD B,$02 | Set B for two iterations | ||
|
Start loop
|
||||
| event_roll_call_0 | EFA2 | LD A,(HL) | Fetch the next coord | |

| EFA4 | JR C,not_at_roll_call | |||
| EFA6 | CP E | |||
| EFA7 | JR NC,not_at_roll_call | |||
| EFA9 | INC HL | On the second iteration advance to hero_map_position_y ($6A..$72) | ||
| EFAA | LD DE,$6A72 | On the second iteration load DE with the Y coordinates of the main gate ($6A..$72) | ||
| EFAD | DJNZ event_roll_call_0 | ...loop | ||
|
Make all visible characters turn forward.
|
||||
| EFAF | LD HL,$800D | Point HL at the visible character's input field (always $800D) | ||
| EFB2 | LD B,$08 | Set B for 8 iterations | ||
|
Start loop
|
||||
| event_roll_call_1 | EFB4 | LD (HL),$80 | Set input to input_KICK | |
| EFB6 | INC L | Point HL at the visible character's direction field (always $800E) | ||
| EFB7 | LD (HL),$03 | Set the direction field to 3 => face bottom left | ||
| EFB9 | LD A,L | Advance HL to the next vischar | ||
| EFBA | ADD A,$1F | |||
| EFBC | LD L,A | |||
| EFBD | DJNZ event_roll_call_1 | ...loop | ||
| EFBF | RET | Return | ||
| not_at_roll_call | EFC0 | XOR A | Make the bell ring perpetually | |
| EFC1 | LD ($A130),A | |||
| EFC4 | LD B,A | Queue the message "MISSED ROLL CALL" | ||
| EFC5 | CALL queue_message | |||
| EFC8 | JP hostiles_pursue | Exit via hostiles_pursue | ||
