| MovePercyRight | 62A2 | XOR A | Write 00 to *PercyFacingDirection (Percy is facing right). | |||||||
| 62A3 | LD ($5FA5),A | |||||||||
|
If *CarryingWormFlag is set, apply an extra boundary check.
|
||||||||||
| 62A6 | LD A,($5FAA) | Jump to MovePercyRight_Apply if *CarryingWormFlag is unset. | ||||||||
| 62A9 | OR A | |||||||||
| 62AA | JR Z,MovePercyRight_Apply | |||||||||
| 62AC | LD A,(IX+$00) | Load A with Percy's X position (*IX+00) + the number of pixels to move (from D) + 04. | ||||||||
| 62AF | ADD A,D | |||||||||
| 62B0 | ADD A,$04 | |||||||||
|
If Percy has gone past the right edge transition into the next room.

||||||||||
| 62B2 | CP $EF | Jump to TransitionRoomRight if Percy's new position is greater than or equal to EF. | ||||||||
| 62B4 | JR NC,TransitionRoomRight | |||||||||
| MovePercyRight_Apply | 62B6 | LD A,(IX+$00) | Load A with Percy's X position (*IX+00) + the number of pixels to move (from D). | |||||||
| 62B9 | ADD A,D | |||||||||
|
If Percy has gone past the right edge transition into the next room.
|
||||||||||
