setlistener("/some/switch", func {
if (cmdarg().getBoolValue()) {
print("turned on");
} else {
print("turned off");
}
});
You can also define the function elsewhere and just call it like that:
on_switch = func {
...
}
setlistener("/some/switch", on_switch);
cmdarg() returns the listened-to property as props.Node object,
so you can use it with all its methods (see $FG_ROOT/Nasal/props.nas),
for example:
print(cmdarg().getPath(), " has been changed to ", cmdarg().getValue())
m.
