Used by the routines at InitialiseDisplayBuffer, ReadRoomGraphicsParameter, RestoreSavedCharacterRecord, ProcessDisplayAction, RecordResultRoomGraphics and RecordResultRoomGraphics_CountCountRemaining.
Prepares the room or object named for the picture, and skips it when the record is not marked for display.

|
Set object pointers.
|
||||
| ProcessObjectDisplayLogic | 51497 | CALL SetObjectPointers | Call SetObjectPointers to point at this object's records. | |
| 51500 | LD A,(41012) | Jump to ProcessObjectDisplayLogic_SavedCharacterMove if the room display parameter is at least 254. | ||
| 51503 | CP 254 | |||
| 51505 | JR NC,ProcessObjectDisplayLogic_SavedCharacterMove | |||
| 51507 | LD IX,(40983) | Read the current character record. | ||
| 51511 | BIT 6,(IX+5) | Jump to ProcessObjectDisplayLogic_Next if the special-description flag is clear. | ||
| 51515 | JR Z,ProcessObjectDisplayLogic_Next | |||
|
No matching handler?
|
||||
| 51517 | XOR A | Jump ahead to ProcessObjectDisplayLogic_Next if CalculateHandlerOffset finds no handler. | ||
| 51518 | CALL CalculateHandlerOffset | |||
| 51521 | JR NC,ProcessObjectDisplayLogic_Next | |||
| 51523 | LD A,(41011) | Read the saved character and call SearchTwoByteTable to search the two-byte table. | ||
| 51526 | CALL SearchTwoByteTable | |||
| 51529 | CP 255 | Jump ahead to ProcessObjectDisplayLogic_MovedMarker if the entry is not the end marker. | ||
| 51531 | JR NZ,ProcessObjectDisplayLogic_MovedMarker | |||
| ProcessObjectDisplayLogic_Next | 51533 | LD A,(40975) | Jump to ProcessObjectDisplayLogic_SavedCharacterMove if the display mode is below 7. | |
| 51536 | CP 7 | |||
| 51538 | JR C,ProcessObjectDisplayLogic_SavedCharacterMove | |||
| 51540 | LD IX,(40979) | Call CalculateHandlerOffset to calculate handler offset. | ||

| 51547 | CALL CalculateHandlerOffset | |||
| 51550 | JR NC,ProcessObjectDisplayLogic_SavedCharacterMove | Jump ahead to ProcessObjectDisplayLogic_SavedCharacterMove if CalculateHandlerOffset finds no handler. | ||
| ProcessObjectDisplayLogic_MovedMarker | 51552 | LD A,(IX+1) | Read the moved marker. | |
| 51555 | LD E,A | |||
| 51556 | LD D,0 | |||
| 51558 | LD HL,43633 | Use the lookup table: object display data at Table_ObjectDisplayData. | ||
| 51561 | DEC DE | Index the word table at Table_ObjectDisplayData and draw that record from ProcessObjectDisplayEntry. | ||
| 51562 | ADD HL,DE | |||
| 51563 | ADD HL,DE | |||
| 51564 | LD E,(HL) | |||

| 51566 | LD D,(HL) | |||
| 51567 | EX DE,HL | |||
| 51568 | JR ProcessObjectDisplayEntry | |||
|
Read the saved character, then use the display records at 40760 as the character record, then check for the end marker.
|
||||
| ProcessObjectDisplayLogic_SavedCharacterMove | 51570 | LD A,(41011) | Call SearchThreeByteTable to search three-byte length table. | |
| 51573 | LD IX,40760 | |||
| 51577 | CALL SearchThreeByteTable | |||
| 51580 | CP 255 | Return zero through ParseInputNumber_ReturnZero if the entry is the end marker. | ||
| 51582 | JP Z,ParseInputNumber_ReturnZero | |||
| 51585 | LD L,(IX+1) | Read the display-record pointer and draw it from ProcessObjectDisplayEntry. | ||
