| F41F | LD HL,$7FF6 | 7FF6 holds the catapult-firing action timer (initially 0x18) | ||
| F422 | DEC (HL) | Has ERIC finished firing the catapult? | ||
| F423 | JR NZ,$F434 | Jump if not | ||
|
This entry point is used by the routines at F4A4 and F533 to restore ERIC's animatory state to what it was before he jumped or threw a punch.
|
||||
| F425 | XOR A | Clear all of ERIC's status flags at 7FFB | ||
| F426 | LD ($7FFB),A | |||
| F429 | LD H,$AC | 0xAC=ERIC | ||
| F42B | CALL $6214 | Update the SRB for ERIC's current animatory state | ||
| F42E | LD L,$66 | Restore ERIC's animatory state to what it was before he fired the catapult, jumped, or threw the punch | ||
| F430 | LD A,(HL) | |||
| F431 | JP $61B0 | Update ERIC's animatory state and location and update the SRB | ||
|
ERIC hasn't finished firing the catapult. Check which phase of the firing action we're at.
|
||||
| F434 | LD A,(HL) | Pick up the current value of the action timer in A | ||
| F435 | LD H,$AC | 0xAC=ERIC | ||
| F437 | CP $12 | Is it time to raise the catapult to eye level? | ||
| F439 | JP Z,$7041 | Jump if so | ||
| F43C | CP $06 | Is it time to start lowering the catapult? | ||
| F43E | JP Z,$706B | Jump if so | ||
| F441 | CP $0C | Is it time to launch the pellet? | ||
| F443 | RET NZ | Return if not | ||
|
It's time to launch the catapult pellet.
|
||||
| F444 | LD L,$60 | Byte 0x60 of ERIC's buffer holds his animatory state | ||
| F446 | LD A,(HL) | Pick this up in A | ||
| F447 | OR $7F | A=0x7F or 0xFF (catapult pellet) | ||
| F449 | INC L | Pick up ERIC's coordinates in DE; they will be the initial coordinates of the catapult pellet | ||
| F44A | LD D,(HL) | |||
| F44B | INC L | |||
| F44C | LD E,(HL) | |||
| F44D | DEC H | H=0xAB (ERIC's catapult pellet) | ||
| F44E | CALL $7057 | Launch the catapult pellet | ||
| F451 | CALL $FE75 | Play the catapult sound effect | ||
| F454 | LD B,$0D | Reprimand message 0x0D: CATAPULTS ARE FORBIDDEN | ||
| F456 | LD H,$AC | 0xAC=ERIC | ||
| F458 | PUSH BC | Save the reprimand message identifier | ||
| F459 | CALL $6E3C | Check whether any teachers saw ERIC throw a punch, fire his catapult, or jump | ||
| F45C | POP BC | Restore the reprimand message identifier to B | ||
| F45D | RET NC | Return if ERIC wasn't seen by a teacher | ||
| F45E | EXX | |||

| F461 | LD D,(HL) | Pick up the coordinates of the teacher who saw ERIC in DE' | ||
| F462 | INC L | |||

| F464 | PUSH DE | |||
| F465 | EXX | |||
| F466 | POP DE | Now DE holds the coordinates of the teacher who saw ERIC | ||
| F467 | LD A,H | A=0xAC (ERIC) | ||
| F468 | JP $7700 | Make the teacher give ERIC lines | ||
