//	GetGOScriptID
//	Purpose:
//		Given the name of the object (from it's pagename), this function will search through it's
//	list of General Object Scripts for a script with a matching name (to see if there is a script
//	for that type/id of object within this DLL).  If a matching scriptname is found, a UNIQUE ID
//	is to be returned back to Descent 3.  This ID will be used from here on out for all future
//	interaction with the DLL.  Since doors are not part of the generic object's, it's possible
//	for a door to have the same name as a generic object (OBJ_POWERUP, OBJ_BUILDING, OBJ_CLUTTER
//	or OBJ_ROBOT), therefore, a 1 is passed in for isdoor if the given object name refers to a
//	door, else it is a 0.  The return value is the unique identifier, else -1 if the script
//	does not exist in the DLL.
int DLLFUNCCALL GetGOScriptID(const char *name, uint8_t isdoor) { return -1; }

//	CreateInstance
//	Purpose:
//		Given an ID from a call to GetGOScriptID(), this function will create a new instance for that
//	particular script (by allocating and initializing memory, etc.).  A pointer to this instance
//	is to be returned back to Descent 3.  This pointer will be passed around, along with the ID
//	for CallInstanceEvent() and DestroyInstance().  Return NULL if there was an error.
void DLLFUNCCALLPTR CreateInstance(int id) { return NULL; }

//	DestroyInstance
//	Purpose:
//		Given an ID, and a pointer to a particular instance of a script, this function will delete and
//	destruct all information associated with that script, so it will no longer exist.
void DLLFUNCCALL DestroyInstance(int id, void *ptr) {}

//	CallInstanceEvent
//	Purpose:
//		Given an ID, a pointer to a script instance, an event and a pointer to the struct of
//	information about the event, this function will translate who this event belongs to and
//	passes the event to that instance of the script to be handled.  Return a combination of
//	CONTINUE_CHAIN and CONTINUE_DEFAULT, to give instructions on what to do based on the
//	event. CONTINUE_CHAIN means to continue through the chain of scripts (custom script, level
//	script, mission script, and finally default script).  If CONTINUE_CHAIN is not specified,
//	than the chain is broken and those scripts of lower priority will never get the event.  Return
//	CONTINUE_DEFAULT in order to tell D3 if you want process the normal action that is built into
//	the game for that event.  This only pertains to certain events.  If the chain continues
//	after this script, than the CONTINUE_DEFAULT setting will be overridden by lower priority
//	scripts return value.
int16_t DLLFUNCCALL CallInstanceEvent(int id, void *ptr, int event, tOSIRISEventInfo *data) {
  return CONTINUE_CHAIN | CONTINUE_DEFAULT;
}

//	SaveRestoreState
//	Purpose:
//		This function is called when Descent 3 is saving or restoring the game state.  In this function
//	you should save/restore any global data that you want preserved through load/save (which includes
//	demos).  You must be very careful with this function, corrupting the file (reading or writing too
//	much or too little) may be hazardous to the game (possibly making it impossible to restore the
//	state).  It would be best to use version information to keep older versions of saved states still
//	able to be used.  IT IS VERY IMPORTANT WHEN SAVING THE STATE TO RETURN THE NUMBER OF _BYTES_ WROTE
//	TO THE FILE.  When restoring the data, the return value is ignored.  saving_state is 1 when you should
//	write data to the file_ptr, 0 when you should read in the data.
int DLLFUNCCALL SaveRestoreState(void *file_ptr, uint8_t saving_state) { return 0; }
