sun direction

Time for me to hit the spotlights with an issue that will most of you laugh at

trying to make a solar panel to follow the sun and if it`s night return to it`s standard position
the panel works after throwing a multiplyer in and if not to picky, it rotates well following the sun when time lapping with the estate tools

the main problem i have is the ground prim that rotates the panel, been at it for the past 2 hours throwing the entire wiki at it trying to create a vector from the sun x and y position to rotate the base prim on the z axis

does anyone have/know a script that just follows the sun on the z axis? (horizontal rotate)?

math has never been my strongest point
Thanks

You might try

vector sun = llGetSunDirection();

rotation sunRot = ZERO_ROTATION;

if (sun.z >= 0.0) {
    sunRot = llAxes2Rot(<sun.x, sun.y, 0.0>, <-sun.y, sun.x, 0.0>, <0.0, 0.0, 1.0>);
}

llSetRot(sunRot);

it`s finally rotating where it`s supposed to rotate to instead of every where else lol

thanks BamBam!

might aswell throw it in if any one wants to play with it aswell as i`m doing it to just fill my island abit

root prim

integer night=0; // 0 = daytime, 1 = nighttime
vector sun;

default
{
    state_entry()
    {
        llSetTimerEvent(5); // Check every 5 minutes
    }
    timer()
    {
        vector sun = llGetSunDirection();

        if (sun.z <= 0) {
            night = 1; // Sun is below the horizon
            llSetLocalRot( <0, 0, 0, 0> );
        } else if (sun.z > 0) {
            night = 0; // Sun is above the horizon

            rotation sunRot = ZERO_ROTATION;

            if (sun.z >= 0.0) {
                sunRot = llAxes2Rot(<sun.x, sun.y, 0.0>, <-sun.y, sun.x, 0.0>, <0.0, 0.0, 1.0>);
            }

            llSetRot(sunRot);

            
            //llSay(0, (string)turn);
        }        
    }
}

child prim

integer night=0; // 0 = daytime, 1 = nighttime
vector sun;

default
{
    state_entry()
    {
        llSetTimerEvent(5); // Check every 5 minutes
    }
    timer()
    {
        vector sun = llGetSunDirection();
        if (sun.z <= 0) {
            night = 1; // Sun is below the horizon
            llSetLocalRot( <0, 0, 0, 0> );
        } else if (sun.z > 0) {
            night = 0; // Sun is above the horizon
            vector target = sun; // A vector to look at.

            vector eul = <0, 180 -(sun.z * 60), 0>; //45 degrees around the z-axis, in Euler form
            eul *= DEG_TO_RAD; //convert to radians rotation
            rotation quat = llEuler2Rot( eul ); //convert to quaternion
            llSetLocalRot( quat ); //rotate the object
        }
    }
}

the 180 in the rotation is just cause my prim is aligned wrong
5 second timer is for testing with instant rotation with estate tools, set it at 300/600 or so
during the night it will rotate back to basic position till the sun comes up (directly from the wiki

have fun
