//  Analog Wall Clock
//  Created by Water Rogers for IBM/Opensource
 
//  Purpose
//  --------------------------------------------------------------
//  This purpose of this script is to show llRotateTexture() in
//  action.  It also uses multiple scripts in different links of
//  the object.
 
//  Requirements
//  --------------------------------------------------------------
//  3 Prims are required for all 3 functions, as well as a texture
//  that looks like a clock hand where the rotation of the object's
//  Roll is 0 degrees.
 
//  Usage
//  --------------------------------------------------------------
//  Put this script into an object, and use the function desired.
//  Hours, minutes, and seconds all affect how and when the texture
//  will rotate.
 
 
//  EVENTS
//  --------------------------------------------------------------
 
display_hours()
{
    //  Get the wallclock, and in order to figure out the hours, divide
    //  the seconds returned from wallclock by 60, then divide that number
    //  by 60.  This will return the hour of the day (in military time).
    //  Since this is the hour hand, we take 360 degrees (a full circle)
    //  and divide it by 12 (the hours on a clock).  This returns 30
    //  degrees - multiply by the current hour, then translate the remainder
    //  to Radians, since that's how rotations are interpretted in SL.
    llRotateTexture(-(((llGetWallclock() / 60) / 60) * 30) * DEG_TO_RAD, ALL_SIDES);
}
 
display_minutes()
{
    //  The same logic applies to minutes, as with hours, except this time we
    //  are only interested by how many minutes have passed rather then hours.
    //  One less mathmatical computation.  Also, 360 divided by 60 segments
    //  equates to 6 degrees.
    llRotateTexture(-((llGetWallclock() / 60) * 6) * DEG_TO_RAD, ALL_SIDES);
}
 
display_seconds()
{
    //  Same as the other two, except the wallclock already returns how many
    //  seconds, so there is no need to do any other math other then to translate
    //  to radians and rotate the texture.
    llRotateTexture(-(llGetWallclock() * 6) * DEG_TO_RAD, ALL_SIDES);
}

    state_entry()

        //  Call the function that this object will represent.  This particular
        //  object happens to be the "seconds" hand of the clock.  The other 2
        //  will call the other 2 respectively.
        display_seconds();
        llSetTimerEvent(1);  //change this to (15) for minutes and (60) for hours for better function in OS.
