44927: Check Task Completion

Used by the routine at GameStart. Check Task Completion for the current Thing Upstairs task.
Check_Task_Completion	44927	LD A,(29358)	Load A with the current task index (CurrentTaskIndex).
	44930	CP 5	Is current task index equal to 5? If not, return.
	44932	RET NZ	Is current task index equal to 5? If not, return.
	44933	LD A,(29364)	Load A with the task status flags (TaskStatusFlags).
	44936	BIT 7,A	Is bit 7 of task status flags set? If so, return.
	44938	RET NZ	Is bit 7 of task status flags set? If so, return.
	44939	LD HL,36585	Point HL at Boney's complex entity state (StateData_Boney).
	44942	LD DE,14	Each entity record is 0014 bytes long, then load that length into DE.
Scan Boney's complex state for the 55 busy pattern that marks task completion.
Check_Task_Completion_ScanBerk	44945	LD A,(HL)	Fetch the next byte from Boney's complex entity state.
	44946	CP 55	Is task status flags equal to 55? If so, jump to Check_Task_Completion_SetBusyBit7.
	44948	JR Z,Check_Task_Completion_SetBusyBit7
	44950	CP 1	Is task status flags equal to 1? If so, jump to Check_Task_Completion_NextBerkRecord.
	44952	JR Z,Check_Task_Completion_NextBerkRecord
	44954	BIT 7,A	Is bit 7 of task status flags set? If so, jump to Check_Task_Completion_NextBerkRecord.
	44956	JR NZ,Check_Task_Completion_NextBerkRecord
	44958	OR A	Is task status flags zero? If not, return.
	44959	RET NZ	Is task status flags zero? If not, return.
Advance to the next Berk state record and keep scanning for completion.
Check_Task_Completion_NextBerkRecord	44960	ADD HL,DE	Add the offset in DE to the pointer in HL.
	44961	JR Check_Task_Completion_ScanBerk	Jump to Check_Task_Completion_ScanBerk to keep testing task-status combinations.
Mark task status bit 7 so Berk's script/dialogue is busy.
Check_Task_Completion_SetBusyBit7	44963	LD HL,29364	Point HL at the task status flags (TaskStatusFlags).
	44966	SET 7,(HL)	Set "Berk script / dialogue busy" (bit 7 of TaskStatusFlags).
	44968	RET	Return.
