Run-time problem

P54 - Only things can be moved

Most problems are detected when Inform translates the source text, but this is one of the exceptions, a "run-time problem" which emerges only during play.

Most everyday items in an Inform work are things - which includes people, containers, vehicles and so on. Those can all move around, at least in theory. The other kinds of object - such as room, region and direction - do not represent portable items, and so can't be moved. An attempt to move them with a line like now the Mirror Room is in Versailles will cause this problem message.
