|0001096||Core Inform||Actions||public||2013-04-04 09:45||2014-05-07 07:33|
|Target Version||Fixed in Version||6L02|
|Summary||0001096: Actor, noun, second noun, etc. change meaning when used in a stored action comparison|
|Description||The attached source generates I6 that calls STORED_ACTION_TY_Adopt and STORED_ACTION_TY_Unadopt, which clobber and unclobber globals like actor, noun, and second. But the other side of the comparison is also evaluated between the calls, so one of the I6 tests reads ``second == actor'', asking whether the stored action's actor and second noun are equal, not whether the stored action's second noun is equal to the current actor.|
|Minimal Source Text To Reproduce|
There is a room. Sal is a woman. Sal carries a frisbee. Foo is a stored action that varies. When play begins: now foo is the action of Sal throwing the frisbee at the player. Instead of looking: showme foo; showme the actor; showme whether or not foo is throwing something at the actor.
|Tags||No tags attached.|
|Effect||(serious/mild) Game compiles but misbehaves|
Behavior is confirmed, but Graham will have to decide whether it's a bug. The semantics of variables in conditions in I7 frequently confuse me...
In this case, it may be the intended behavior for "actor", "noun", "second noun" to effectively be symbols in the context of a condition, rather than naive global variables.
|If it is intended, then let this be a request that the behavior be documented in WI 12.20.|
I've clarified this in the documentation.
The semantics of I7 here amount to whatever will enable the functionality of the whole thing to continue hanging by a thread. But I think it's reasonable, just about.
