9CF2: Process Character Action Parameter
Used by the routines at ProcessCharacterActionWithText, StoreSetMarkPrintPoliceLine, PrintSurprisedRemarkOnce and StoreSetMarkPointer.
Stores the room picture, and counts down while the object is not in the character's room. When the character holds it, stores a fresh delay once the counter has run out.
Input
HL Pointer to counter/state variable
C Room display parameter
DE (preserved on stack)
ProcessCharacterActionParameter 9CF2 LD A,C Call CheckObjectInCharacterLocation to check object in character location.
9CF3 LD ($A034),A
9CF6 CALL CheckObjectInCharacterLocation
9CF9 JR Z,ProcessCharacterActionParameter_Next Jump ahead to ProcessCharacterActionParameter_Next when this character holds the object.
9CFB DEC (HL) Jump to ProcessCharacterActionParameter_0 if the count does not become negative.
9CFC JP P,ProcessCharacterActionParameter_0
9CFF INC (HL) Count one more in the pointer.
ProcessCharacterActionParameter_0 9D00 POP DE Restore DE from the stack.
9D01 RET Return.
When the counter has run out, stores this character's attribute plus thirty.
ProcessCharacterActionParameter_Next 9D02 LD A,(HL) Jump back to ProcessCharacterActionParameter_0 while this byte is not zero.
9D03 AND A
9D04 JR NZ,ProcessCharacterActionParameter_0
9D06 LD A,$0F Case, then call GetRandomNumber to take a random number.
9D08 CALL GetRandomNumber
9D0B ADD A,$1E Advance the result by 1E.
9D0D LD (HL),A Store the result at the pointer.
9D0E XOR A Clear A.
9D0F RET Return.
