| 52193 | PUSH IY | Transfer address of complex state data for pushed entity from IY... | ||||||
| 52195 | POP IX | ...to IX | ||||||
| 52197 | CALL 54569 | Check pushed entity for collision with another impassable / pushable entity immediately to the right... | ||||||
| 52200 | JR C,52207 | ...and if a collision has not occurred, then skip ahead to 52207 | ||||||
| 52202 | CP 129 | If collision was with entity of class 129 (causes other entities to start falling)... | ||||||
| 52204 | JR Z,52235 | ...then skip ahead to 52235 | ||||||
| 52206 | RET | Return (as Drutt can't push two entities) | ||||||
|
No knock-on collision

| 52207 | LD A,(34235) | Load E with width of current room (chars) + 99... | ||||||
| 52210 | SUB 2 | ...minus 2... | ||||||
| 52212 | LD E,A | ... | ||||||
| 52213 | LD A,(IX+7) | ...and if x-coordinate of right edge of pushed entity is less than this... | ||||||
| 52216 | CP E | ...i.e. not yet at right edge of room... | ||||||
| 52217 | JR C,52227 | ...then skip ahead to 52227 | ||||||
| 52219 | CALL 54505 | Load B with index of room to right of current character's current room... | ||||||
| 52222 | RET Z | ...and if there is no room to the right then return | ||||||
| 52223 | CALL 54313 | Move pushed entity into room to the right, if appropriate... | ||||||
| 52226 | RET NC | ...and if pushed entity can't enter new room then return | ||||||
| 52227 | INC (IX+5) | Move pushed entity right one character... | ||||||
| 52230 | INC (IX+7) | ... | ||||||
| 52233 | XOR A | Load A with zero (see trivia) | ||||||
| 52234 | RET | Return | ||||||
| 52235 | CALL 55516 | Set can-fall flag and set initial velocity factor of 2 for pushed entity | ||||||
| 52238 | CALL 52227 | Move pushed entity right two characters... | ||||||
