Used by the routine at Update_Task_Four_Entities.
Advance task-four entity scripts and start/stop the entity when game event flags at GameEventFlags change.
|
||||
| Update_TaskFourEntityState | CAC4 | LD A,($72B3) | Load A with the game event flags (GameEventFlags). | |
| CAC7 | BIT 7,A | Is bit 07 of game event flags set? If so, jump to AdvanceScriptInstruction. | ||
| CAC9 | JP NZ,AdvanceScriptInstruction | |||
| CACC | BIT 7,(IX+$00) | Is bit 07 of the current entity's entity type set? If so, jump to Update_TaskFour_StopEntity. | ||
| CAD0 | JR NZ,Update_TaskFour_StopEntity | |||
| CAD2 | BIT 1,A | Is bit 01 of game event flags set? If so, jump to AdvanceScriptInstruction. | ||
| CAD4 | JP NZ,AdvanceScriptInstruction | |||
|
This entry point is used by the routine at ScriptRoutine_TaskFourClearScriptFlags.
Shared entry used by script routine ScriptRoutine_TaskFourClearScriptFlags to start the task-four entity script.
|
||||
| Update_TaskFour_StartEntity | CAD7 | SET 7,(IX+$00) | Set bit 07 of the current entity's entity type. | |
| CADB | XOR A | Clear the current task phase (idle). | ||
| CADC | LD ($72AF),A | Set the current task phase (CurrentTaskPhase). | ||
| CADF | LD HL,$CA23 | Point HL at task-four script Data_TaskFourScript. | ||
| CAE2 | LD ($72CF),HL | Store HL in the active script cursor (Pointer_ActiveScriptCursor). | ||
| CAE5 | RET | Return. | ||
|
Stop the task-four entity when game-event bit 01 is set: clear type bit 07 and continue the script.
|
||||
| Update_TaskFour_StopEntity | CAE6 | BIT 1,A | Is bit 01 of game event flags set? If not, return. | |
| CAE8 | RET Z | |||
| CAE9 | RES 7,(IX+$00) | Reset bit 07 of the current entity's entity type. | ||
