Really? Neat!
With regards to actorFace, its used in quite a few places. For example:
[0C86] (B8) printActor.msg(:sound:"Don't worry guys!")
[0CAA] (AC) soundKludge([268,97,0,1])
[0CBA] (5E) startScript(2,71,[8,7,6,48,136])
[0CD3] (CA) delayFrames(2)
[0CD7] (81) faceActor(2,6)
[0CDE] (81) faceActor(3,6)
[0CE5] (81) faceActor(1,6)
[0CEC] (81) faceActor(4,6)
[0CF3] (6C) breakHere()
[0CF4] (5D) unless ((array236[6] == 0)) jump cf3
[0D01] (82) animateActor(6,245)
[0D08] (82) animateActor(6,4)
[0D0F] (A9) wait.waitForMessage()
[0D11] (82) animateActor(6,5)
[0D18] (BA) talkActor(:sound:"This time I KNOW I can stop him!",6)
(One of the cutscenes near to the end. Actor 1 is Bernard, 2 is
Laverne, 3 is Hoagie, 4 is Dr Fred, 6 is green tentacle)
[067D] (81) faceActor(8,VAR_EGO)
[0684] (B0) delay(30)
[0688] (BA) talkActor(:sound:"Voila.",8)
[06A3] (A9) wait.waitForMessage()
[06A5] (BA) talkActor(:sound:"You're quite a man.",3)
[06CD] (A9) wait.waitForMessage()
[06CF] (BA) talkActor(:sound:"Yes, I know.",8)
[06F0] (A9) wait.waitForMessage()
(Near the end of the cutscene which plays when GW cuts down the cherry
tree. Actor 8 is GW, 3 is Hoagie)
I couldn't find any reference to setActorDirection in the de-compiled
DOTT or SAMNMAX scripts, unless it's called something obscure or it's
in a local script. Looking at the V5 opcodes, it doesn't appear to be
there at all, which suggests to me it could be a late V6 addition
perhaps.
In any case, setActorDirection accepts degrees, whereas actorFace
accepts actors and objects (though mainly just actors).
Sadly i seem to have mislaid my patch to rd.c. Although the auto
dumper did suffer from a little issue whereby the script indexes
weren't being dumped, which made following everything a bit difficult.
Not sure if i was using the wrong variable or what.
(I'll probably do a rewrite and dump the object and room info's
related to script as well)

One has a verb to show it, like so.
setCurrentVerb(SntcLine);
initVerb();
setVerbName("%v{sntcVerb} %n{sntcObjA} %s{sntcPrepo}
%n{sntcObjB}");
setVerbXY(160,145);
setVerbColor(color);
setVerbHiColor(hiColor);
verbCenter();
Then all you need to do to update it is to redraw it, like so:
setCurrentVerb(SntcLine);
redrawVerb();
If you look at the code in the road example, you'll notice all the
variables listed in the string passed to "setVerbName" are listed in
common.scc, with the exception of sntcPrepo which is listed in
common.h. So in essence, the entire sentence line is powered by script.
I'm not sure what the problem could be with your actor names. As long
as you detect the actor and assign sntcObjA or sntcObjB to it, and it
has a name, you should be able to see it.

Interesting - perhaps in the original these debug messages are printed
somewhere else, like a com port for example?
