6.3.8 Exchange cons: E>RH

This non-terminal command has sub-commands for exchanging all room constructions (swapping places) in their entirety: foreground, background and extension. If any of the following positions are referencing either of the exchanging places, they are updated to point to the exchanged places.

Each sub-command is non-input and represents a particular place mapping.

RH>HVR

Every sub-command works in the same way: they immediately exchange the constructions of the currently displayed room according to their particular mapping. These sub-commands have the following meanings:

H

horizontal reflection. Inverts the start facing direction of guards and the kid, and current facing direction of character instances as well.

V

vertical reflection

R

random place within the currently selected room

To apply the exchange to just a couple of constructions see Exchange cons: E>CH.
