@listen
@listen
Section titled “@listen”@listen <object>[=<pattern>]
Sets the object’s listen pattern to <pattern>, which can have wildcards. Whenever something the object hears matches the pattern, the object’s ahear/amhear/aahear attribute will be triggered. In addition, anything inside the object will hear it as well, if the speaker passes @lock/infilter.
Rather than using @listen, it’s recommended you use ^-listening patterns, which can be set in any attribute similar to $-commands. This allows for descriptive attribute names, and also allows multiple patterns per object. See listening listen patterns for more information.
For example:
> @listen Chair=*Since the wildcard (*) matches anything, anyone inside the object will hear anything said outside it.
> @listen Butler=* has arrived.> @ahear Butler=:walks over to the new arrival and takes %p coat.In this case, the listen pattern is met whenever someone ‘arrives’ in the room, and then the object does whatever is inside its @ahear attribute.
Cyclonus has arrived.Butler walks over to the new arrival and takes his coat.Listening behavior
Section titled “Listening behavior”An object “hears” anything that another player standing in the same room would hear. For example, if you type in a command, the object does NOT hear it. If the command has a result that people in the room hear, the object will hear it.
For example:
> @listen Recorder=@emit *> @ahear Recorder=:records %0> @emit Whee!Whee!In this example, the Recorder’s listen-pattern is NOT matched, because it doesn’t hear the ‘@emit Whee!’, it only hears the ‘Whee!’ part, which doesn’t match.
> @listen Recorder=Cyclonus says, "*"> say Whee!Cyclonus says, "Whee!"Recorder records: Whee!::: seealso
