Timed Lights - Need to know...

I need to figure out how much time is between sunrise and sunset. If you have any idea, please reply. I really need a specific response, as specific as possible so its realistic. I've heard roughly 3-4 hours, but I can't work with that

Thanks.

Talk to Ama Omega... he rigged our clock tower to tell our windows in the village when night is so they glow bright yellow. (:

There is a scripting command that tells the location of the sun in the sky - this is the one to use for timed street lights.

Hey, I found out the llGetSunDirection; code but im not quite sure how to use it. All i have is llGetSunDirection();
I tried to make the object say where the sun was, but being a newb to scripting has been troublesome. Any help is appreciated, and yes I contacted Ama

I think llGetTimeOfDay(), which (I'm pretty sure) returns the "in world" time, might work. (As opposed to llGetWallclock(), which returns server time).

Xylor

vector sun = llGetSunDirection();
integer isDay = ( sun.z > 0 );

isDay will be TRUE if it is day, FALSE if it is night.

Well i compiled a script to make it work properly...well in theory it SHOULD have worked, but what it does is just flash the colour i need it to change to then goes back to the original, but if you check in textures, under colour, it worked. Here's an example of what i have:

default
{
state_entry()
{
vector sun = llGetSunDirection();
integer isDay = ( sun.z > 0 );
if ( isDay = FALSE );
{
llSetColor(<1.0, 0.0, 0.0>, ALL_SIDES);
}
if ( isDay = TRUE );
{
llSetColor(<0.2, 0.0, 0.0>, ALL_SIDES);
}

}
touch_start(integer total_number)
{
llSay(0,""+(string)llGetSunDirection());
}

}


Let me know whats wrong with it.

Change your isDay = FALSE and isDay = TRUE to isDay == FALSE and isDay == TRUE, otherwise you are assigning the value in your if statement, which is definitely not what you want, = is assignment == is comparison.

Something else you could do, because isDay is returning a boolean value (i.e. true or false) and would make it simpler:

if (isDay) //This will happen if isDay is TRUE
{
llSetColor(<0.2, 0.0, 0.0>, ALL_SIDES);
}
else //Otherwise, this will happen
{
llSetColor(<1.0, 0.0, 0.0>, ALL_SIDES);
}

Also, don't put semicolons after your "if" or "else" statements.
or anything that is followed by an opening brace {

Well i'm really close now. I did what you said about the ==. but now they dont turn off or on based on the sun. See I added a say line so i know if it works or not, and when i reversed the true and false to make it think it was night, it ran through both llSay and said both of them. The lights do work if i reset the script though. Here's a copy of what i have:

default
{
state_entry()
{
vector sun = llGetSunDirection();
integer isDay = ( sun.z > 0 );
if ( isDay == FALSE );
{
llSetColor(<1.0, 0.0, 0.0>, ALL_SIDES);
llSay(0, "Lights Activated";
}
if ( isDay == TRUE)
{
llSetColor(<0.2, 0.0, 0.0>, ALL_SIDES);
llSay(0, "Lights Deactivated";
}

}
touch_start(integer total_number)
{
llSay(0,""+(string)llGetSunDirection());
}

}

So like i said, when i activate the script, it says "Lights Activated" then immidiatly after "Lights Deactivated" but they stay on.. or off dependant on the day. And i tried working with the else statement, I probably didn't do it right cuz it doesnt work either

Your code that checks the value of isDay is in the state_entry handler for the default state; that means it's being executed only once, when the script starts running. (Resetting the script starts it over again.)

You want to check the value of isDay at regular intervals, say every five or ten minutes. For that you need the timer event. Try this:

default
{
    state_entry()
    {
        // set interval at 300 seconds, i.e. five minutes
        llSetTimerEvent( 300.0 );
    }

    timer()
    {
        vector sun = llGetSunDirection();
        integer isDay = ( sun.z > 0 );
        if ( isDay == FALSE );
        {
            llSetColor(<1.0, 0.0, 0.0>, ALL_SIDES);
            llSay(0, "Lights Activated");
        }
        if ( isDay == TRUE)
        {
            llSetColor(<0.2, 0.0, 0.0>, ALL_SIDES);
            llSay(0, "Lights Deactivated");
        }

    }

    touch_start(integer total_number)
    {
        llSay(0,""+(string)llGetSunDirection());
    }

}

Another thing you could try is have an object using light material rez inside you light which wouldn't be a light material object and have it die when not needed. This might cut down on lighting taxes as well.

Thats a good idea, but i dont need it lol, its only 10 bucks to have them both out

This is a follow up -

The lights do currently work
I'd like to say thank you to everyone who contributed to the script.

So umm yeah if u need the script IM me in game and ill give u a copy.

Thanks again!
