[matchonce] ; optional parameter
[ <matchkey > <matchvalue> weight nnn required ]
}
- matchonce (off by default): means that the rule is deactivated after the first time it is matched
Note:Additional "unnamed" criteria can be specified inline in the rule using the same syntax as for defining a criterion, except for the criterion keyword and the criterion name keys.Here is an example from scripts/talker/npc_alyx.txt.
