Run script when variable changes
|
What's the best way to run a script when the value of a variable changes? There seems to be no way to match MXP entity publication with an MXP trigger, which is rather what I'm after, but running on a value change would actually be better.
It seems clear that button captions that are variables, as well as gauges, update themselves when the associated value changes, so I'm hoping to add similar functionality to a script, somehow. |

A trigger of type expression is what you want, with the variable as the pattern

| Code: |
<?xml version="1.0" encoding="ISO-8859-1" ?>
<cmud>
<trigger type="Expression" priority="28310" copy="yes">
<pattern>@test</pattern>
<value>#SAY The value of the test variable changed!</value>
</trigger>
</cmud> |
Then on the command line, type test = 1, test = 2, test = "abc", etc. |
