Colours the level display for each player green, then prints each player's level as "L" followed by two digits (1UP on the left, 2UP on the right). Flag_ActivePlayer decides which of the active and inactive player levels is used for each.
|
||||
|
Colour the 1UP level green. Both levels are on pixel row 8 (character row 1): 1UP starts at X=72 (column 9) and 2UP starts at X=160 (column 20).
|
||||
| PrintPlayerLevels | 62956 | LD HL,2120 | Set the 1UP level pixel co-ordinates in HL (Y=8 X=72). | |
| 62959 | CALL ColourLevelsGreen | Call ColourLevelsGreen to colour the three level characters green. | ||
|
Colour the 2UP level green.
|
||||
| 62962 | LD HL,2208 | Set the 2UP level pixel co-ordinates in HL (Y=8 X=160). | ||
| 62965 | CALL ColourLevelsGreen | Call ColourLevelsGreen to colour the three level characters green. | ||
|
Is the active player 1UP or 2UP?
|
||||
| 62968 | LD A,(24165) | If Flag_ActivePlayer is not zero, jump to Handler_PrintPlayerLevels. | ||
| 62971 | AND A | |||
| 62972 | JR NZ,Handler_PrintPlayerLevels | |||
|

| 62977 | CALL Print_ActivePlayerLevel | Call Print_ActivePlayerLevel. | ||
| 62980 | LD HL,2208 | Set the 2UP level pixel co-ordinates in HL (Y=8 X=160). | ||
| 62983 | JR Print_InactivePlayerLevel | Jump to Print_InactivePlayerLevel. | ||
|

| 62988 | CALL Print_InactivePlayerLevel | Call Print_InactivePlayerLevel. | ||
|
Handles the 2UP level.
|
||||
| 62991 | LD HL,2208 | Set the 2UP level pixel co-ordinates in HL (Y=8 X=160). | ||
|

|
||||
| PrintLevel | 63002 | PUSH BC | Stash BC on the stack. | |
| 63003 | ADD A,48 | Add 48 to convert to an ASCII character (starting at "0"). | ||
| 63005 | CALL PrintLevelMessaging | Call PrintLevelMessaging. | ||
| 63008 | POP BC | Restore BC from the stack. | ||
|
Now move onto the second digit held in C.
|
||||
| 63009 | LD A,C | A=C. | ||
| 63010 | ADD A,48 | Add 48 to convert to an ASCII character (starting at "0"). | ||
| 63012 | CALL PrintLevelMessaging | Call PrintLevelMessaging. | ||
