Ambient sound triggered by time of day

I have a script that I was given that plays different sounds day vs. night. I would like to create a third category to play sounds at dusk. I have a general idea how to do it... any help here? The script is below:

list daySounds = ["American Oriole", "Cardinal", "Red-tailed Hawk", "Robin", "Song Sparrow", "Tree Swallow", "Locust"];
list nightSounds = ["Great Horned Owl"];

list nightAmbient = ["Cricket"];

default {
state_entry() {
llStopSound();
llSetTimerEvent(2.0);
}

timer() {
vector time = llGetSunDirection();
list myList;
float density = 0.9;

if (time.z > 0.0) {
myList = llListRandomize(daySounds, 1);
} else {
myList = llListRandomize(nightSounds, 1);
density = 0.98;

// Ambient nighttime sound
if (llFrand(1.0) > 0.85) {
llStopSound();
} else {
llLoopSound(llList2String(nightAmbient, 0), 1.0);
}
}

if (llFrand(1.0) > density) {
llTriggerSound(llList2String(myList, 0), 1.0);
}
}
}

You need the scripting forum. They're a real helpful bunch over there. It's about ten forums down. In the Content Creation section.

Yup there it is. Thanks...

I dropped a tested script that you can adapt into your inventory in game. I wrote a script that changes a texture according to the position of the sun (dilates cat eyes). I have four light states, day, night, low light (beginning of dawn or end of dusk) and medium light for end of dawn or beginning of dusk. Have fun.

Also, when posting scripts, it's nice to enclose the script in the PHP tags,

.
You can do that manually or if you use the enhanced editor it's the icon.

Doing so gives it syntax color coding and with proper copying and pasting preserves the indentation in the script.

Even if I did post in the wrong forum.
