807A: Create Delay
The handler for entities that have nothing to do. If the entity is one of the first three 16-byte records, which start at CreatureRecords, then a short delay loop is run before returning. Otherwise it returns straight away.
Input
IX The entity
CreateDelay 807A PUSH IX Copy IX to HL (using the stack).
807C POP HL
807D LD DE,$EE60 Point DE at the creatures at CreatureRecords.
8080 AND A Subtract DE from HL, to get the offset of the entity into the 16-byte records.
8081 SBC HL,DE
8083 LD A,H Return if the high byte of the offset is not zero.
8084 AND A
8085 RET NZ
8086 LD A,L Return if the low byte of the offset is 30 or more.
8087 CP $30
8089 RET NC
808A LD HL,$00C0 HL=00C0 (the length of the delay).
CreateDelay_Loop 808D DEC HL Decrease the delay counter by one.
808E LD A,H Loop back to CreateDelay_Loop until the delay counter is zero.
808F OR L
8090 JR NZ,CreateDelay_Loop
8092 RET Return.
