| B18B | LD A,(IY+$07) | Load A with the referenced entity's x-coordinate. | ||
| B18E | CP $AB | Is referenced entity's x-coordinate less than AB? If so, jump to Update_Drutt_Animation_NextEntity. | ||
| B190 | JR C,Update_Drutt_Animation_NextEntity | |||
| B192 | LD A,$B1 | Load A with B1. | ||
| B194 | CP (IY+$08) | Is B1 less than the referenced entity's x-extent? If so, jump to Update_Drutt_Animation_NextEntity. | ||
| B197 | JR C,Update_Drutt_Animation_NextEntity | |||
| B199 | BIT 5,(IY+$01) | Is bit 05 of the referenced entity's flags byte 1 set? If so, jump to Update_Drutt_Animation_NextEntity. | ||
| B19D | JR NZ,Update_Drutt_Animation_NextEntity | |||
| B19F | CP $AB | Compare B1 with AB. | ||
| B1A1 | LD A,(IY+$00) | Load A with the referenced entity's entity type. | ||
