40178: 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 40178 LD A,C Call CheckObjectInCharacterLocation to check object in character location.
40179 LD (41012),A
40182 CALL CheckObjectInCharacterLocation
40185 JR Z,ProcessCharacterActionParameter_Next Jump ahead to ProcessCharacterActionParameter_Next when this character holds the object.
40187 DEC (HL) Jump to ProcessCharacterActionParameter_0 if the count does not become negative.
40188 JP P,ProcessCharacterActionParameter_0
40191 INC (HL) Count one more in the pointer.
ProcessCharacterActionParameter_0 40192 POP DE Restore DE from the stack.
40193 RET Return.
When the counter has run out, stores this character's attribute plus thirty.
ProcessCharacterActionParameter_Next 40194 LD A,(HL) Jump back to ProcessCharacterActionParameter_0 while this byte is not zero.
40195 AND A
40196 JR NZ,ProcessCharacterActionParameter_0
40198 LD A,15 Case, then call GetRandomNumber to take a random number.
40200 CALL GetRandomNumber
40203 ADD A,30 Advance the result by 30.
40205 LD (HL),A Store the result at the pointer.
40206 XOR A Clear A.
40207 RET Return.
