53815: Fetch Object Data Pointer
Used by the routines at CharacterAction_BasilPhipps, CheckObjectInCharacterLocation, CheckCharacterState, PointToObjectAttributeByte, CalculateObjectPointerOffset, ProcessEntryWithCounter, ProcessDisplayAction, CheckObjectLocationMatch, GetObjectLocation, CheckObjectMother, GetObjectAttribute, GetObjectMotherID, TestObjectHasSpecialDescription, ProcessObjectAttribute_C8C6, SetObjectPointers, ProcessObjectDisplayEntry, ProcessCharacterDisplay_CBC2, ProcessLocationTokenDisplay, CheckCharacterIDRange, IsCharacterTheChinaMan, PrintObjectDescription, PrintLocationExits, 56587, 56629, PrintObjectDescriptionText, 57292, 57402, 57723, 58905 and UpdateObjectLocation.
Looks up an object in the objects table and returns a pointer to it's data structure.
Input
A Object ID
Output
IX Pointer to object data
FetchObjectDataPointer 53815 LD IX,35695 IX=Table_Objects.
53819 CALL SearchThreeByteTable Call SearchThreeByteTable.
This will be restored back into HL by the end of the routine.
53822 PUSH HL Stash HL on the stack temporarily.
Pretty clever way of using the stack here.
53823 LD L,(IX+1) Load the object pointer into HL.
53826 LD H,(IX+2)
53829 EX (SP),HL Swap the *SP with the object pointer, restoring HL to the original value.
53830 POP IX Restore the object pointer into IX (from the stack).
53832 RET Return.
