Continues from F862. Controls MR WACKER as he walks from the vicinity of the stinkbomb cloud over to the nearest closed window, opens it, and walks back again.
|
||||||||
| F939 | LD L,$15 | Pick up the x-coordinate of the window to be opened from byte 0x15 of MR WACKER's buffer | ||||||
| F93B | LD A,(HL) | |||||||
| F93C | LD L,$01 | Byte 0x01 of MR WACKER's buffer holds his current x-coordinate | ||||||
| F93E | CP (HL) | Has MR WACKER reached the window yet? | ||||||
| F93F | JP NZ,$6420 | Keep going if not | ||||||
| F942 | CALL $61B4 | Update the SRB for MR WACKER's current animatory state and location | ||||||
| F945 | OR $07 | A=animatory state of MR WACKER with his arm up | ||||||
| F947 | CALL $7746 | Place address F94A (below) into bytes 0x11 and 0x12 of MR WACKER's buffer and update his animatory state | ||||||
|
The address of this entry point is placed into bytes 0x11 and 0x12 of MR WACKER's buffer by the instruction above when he has reached the window that needs opening.
|
||||||||
| F94A | LD L,$11 | Replace the address of this entry point in bytes 0x11 and 0x12 of MR WACKER's buffer with F956 | ||||||
| F94C | LD (HL),$56 | |||||||
| F94E | LD B,$01 | B=1 (open window) | ||||||
| F950 | LD L,$16 | Pick up the window identifier (0x40/0x80) from byte 0x16 of MR WACKER's buffer | ||||||
| F952 | LD A,(HL) | |||||||
| F953 | JP $70BF | Open the window and lower MR WACKER's arm | ||||||
|
This entry point is used after the window has been opened.
|
||||||||
| F956 | CALL $61B4 | Update the SRB for MR WACKER's current animatory state and location | ||||||
| F959 | XOR $80 | A=animatory state of MR WACKER facing left | ||||||
| F95B | CALL $7746 | Place address F95E (below) into bytes 0x11 and 0x12 of MR WACKER's buffer and update his animatory state | ||||||
|
This entry point is used after MR WACKER has turned round to begin his return journey from the window.
|
||||||||
| F95E | LD L,$00 | Point HL at byte 0x00 of MR WACKER's buffer | ||||||
| F960 | BIT 0,(HL) | Is MR WACKER midstride? | ||||||
| F962 | JP NZ,$63FD | Finish his stride if so | ||||||
| F965 | LD L,$13 | Byte 0x13 stores MR WACKER's x-coordinate before he went off to the window; pick this up in A | ||||||
| F967 | LD A,(HL) | |||||||
| F968 | LD L,$01 | Byte 0x01 of MR WACKER's buffer holds his x-coordinate | ||||||
| F96A | CP (HL) | Is MR WACKER at his pre-window-opening position? | ||||||
| F96B | JP NZ,$6420 | Continue his return journey if not | ||||||
|
MR WACKER has now returned to the spot where the stinkbomb first offended his nostrils.
|
||||||||
| F96E | LD L,$12 | Remove the routine address (F95E above) from bytes 0x11 and 0x12 of MR WACKER's buffer | ||||||
| F970 | LD (HL),$00 | |||||||
| F972 | JP $75A0 | Restore MR WACKER's original animatory state and update SRB | ||||||
