This type of trigger is used specifically to provide information to an observer in the room about an affect that is currently in the room. For instance the poison gas affect uses this technique to inform the player that there is a cloud of poisonous vapours.
@n - The mobile "looking" in the room.
Example:
protect { if( %canSee( @n ) ) { %echoTo( "A cloud of dark swirling poisonous vapors " \ "surrounds you.", @n ) } endif } endprotect |
