||||||||
| Advance_Falling_Entity | 45539 | CALL Test_EntityOverlap | Call Test_EntityOverlap to test Entity Overlap? If so, jump to Advance_Falling_Entity_LowerY. | |||||
| 45542 | JR C,Advance_Falling_Entity_LowerY | |||||||
| 45544 | CP 33 | Is A equal to 33? If not, jump to Advance_Falling_Entity_LowerY. | ||||||
| 45546 | JR NZ,Advance_Falling_Entity_LowerY | |||||||
| 45548 | LD A,(29365) | Load A with the task-two flags (TaskTwoFlags). | ||||||
| 45551 | SET 1,A | Set "task-two script should advance" (bit 1 of TaskTwoFlags). | ||||||
| 45553 | LD (29365),A | Set the task-two flags (TaskTwoFlags). | ||||||
| 45556 | XOR A | Clear A as a false / no-match result. | ||||||
| 45557 | RET | Return. | ||||||
|
Lower the falling entity one character; keep falling, or relocate it when it reaches the floor band.
|
||||||||
| Advance_Falling_Entity_LowerY | 45558 | DEC (IX+5) | Move this entity one character up. | |||||
| 45561 | DEC (IX+6) | |||||||
| 45564 | LD A,(IX+6) | Load A with the current entity's y-extent. | ||||||
| 45567 | CP 12 | Is the current entity's y-extent less than 12? If so, jump to Advance_Falling_Entity_RelocateAtFloor. | ||||||
| 45569 | JR C,Advance_Falling_Entity_RelocateAtFloor | |||||||
| 45571 | SET 2,(HL) | Set the falling-entity latch (bit 2 of GameEventFlags). | ||||||
| 45573 | SCF | Signal success. | ||||||
| 45574 | RET | Return. | ||||||
|
Snap the fallen entity into room 3 at floor x 109 and finish the fall.
|
||||||||
| Advance_Falling_Entity_RelocateAtFloor | 45575 | LD (IX+4),3 | Write 3 to the current entity's room index. | |||||
| 45579 | LD A,(IX+8) | Load A with the current entity's x-extent. | ||||||
| 45582 | SUB (IX+7) | Subtract the current entity's x-coordinate from A. | ||||||
| 45585 | LD C,A | Keep the current entity's x-extent in C for later. | ||||||
| 45586 | LD A,109 | Load A with floor x-coordinate 109. | ||||||
| 45588 | LD (IX+7),A | Set the current entity's x-coordinate. | ||||||
| 45591 | ADD A,C | Add the saved count in C to A. | ||||||
| 45592 | LD (IX+8),A | Set the current entity's x-extent. | ||||||
