Help with trigger, two cases
|
On the MUD I'm playing you can assign labels to players that can contain any length of letters.
I'm writing a trigger that matches two cases, both with and without labels.
These are the texts that I want to be able to match.
| Code: |
Player has arrived from the south.
Player (leader) has arrived from the south.
|
The following trigger works OK:
| Code: |
<trigger priority="9280" case="true" id="928">
<pattern>^(%w){ ~(leader~)|} has arrived from the *.$</pattern>
<value>#Show {Match! player=%1}</value>
</trigger>
|
However, here I have specified the label as "leader" and if I want to use different labels (I want to match all)
it doesn't work. When I replace leader with * in the following example it doesn't work.
| Code: |
<trigger priority="9280" case="true" id="928">
<pattern>^(%w){ ~(*~)|} has arrived from the *.$</pattern>
<value>#Show {Match! player=%1}</value>
</trigger>
|
Any ideas why? Maybe there is a better way of writing this trigger? |

This Regex should work for you:
| Code: |
| ^(\w+)\s(?:\(.+\)\s)?has arrived from the |
Make sure you check the box for Regular Expression
If you know the types of characters you might have for the label, it's best to not use the ".+" pattern (the dot character matches almost everything). Such as if you know you'll just have alpha-numeric characters and spaces, you can replace ".+" with "[\w\s]+" |

Thanks. I figured it would be best to use regular expressions to solve this. Since I'm really bad at writing them I try to avoid them. Just curious, is it not possible to use * inside {alternative 1|alternative 2} in zscript because that is what's not working for me.

No, you can't use wildcards in expression lists.

Actually, there is an option for this. Look in the Scripting page of the Preferences and you'll see an option called "Allow wildcards within {} trigger patterns". Try turning that on. Just keep in mind that putting wildcards within {} lists will slow the triggers down, so it's best to avoid them when possible.
