Drutt will only push other entities when he is under player control. If he is not, then he will just pass through pushable entities.
Used by the routine at 52142.
|
||||||||
| 52148 | CALL 54569 | Check Drutt for collision with another impassable / pushable entity immediately to the right... | ||||||
| 52151 | JR C,52182 | ...and if a collision has not occurred, then skip ahead to 52182 | ||||||
|
At this point, a collision has occurred, so IY points to the complex state data entry of the entity with which Drutt has collided
|
||||||||
| 52153 | CP 22 | If collision was with an entity of class 22 or greater (can't be picked up)... | ||||||
| 52155 | JR NC,52171 | ...then skip ahead to 52171 | ||||||
| 52157 | BIT 1,(IX+9) | If Drutt's under-player-control flag is reset... | ||||||
| 52161 | JR Z,52182 | ...then skip ahead to 52182 (move Drutt right without pushing anything) | ||||||
| 52163 | PUSH IX | Store IX (address of current level's complex state data for Drutt) | ||||||
| 52165 | CALL 52193 | Advance position of entity pushed right by Drutt | ||||||
| 52168 | POP IX | Restore IX (address of current level's complex state data for Drutt) | ||||||
| 52170 | RET | Return | ||||||
|
Collision with entity of class 22 or greater
|
||||||||
| 52171 | CP 129 | If collision was with entity of class 129 (causes other entities to start falling)... | ||||||
| 52173 | JR Z,52182 | ...then skip ahead to 52182 | ||||||
|
At this point, the entity to Drutt's right is neither passable nor pushable.
|
||||||||
| 52175 | POP BC | Remove top value from stack (i.e. return address to routine that called this routine) | ||||||
| 52176 | LD HL,51630 | Point HL at script data for Drutt swapping depth levels... | ||||||
| 52179 | JP 48098 | ...and execute | ||||||
|
No collision, not under player control or collision with entity of class 129
|
||||||||
| 52182 | CALL 54313 | Move Drutt into room to the right, if appropriate... | ||||||
| 52185 | RET NC | ...and if Drutt can't enter new room then return | ||||||
| 52186 | INC (IX+5) | Move Drutt right one character... | ||||||
| 52189 | INC (IX+7) | ... | ||||||
| 52192 | RET | Return | ||||||
