Keeps track if the sun in a region is day or night.
You can use this script to turn a light on automatically when it becomes night time and off in the day. Just add your script snippets where it says "Do something here" below.
integer time = 120; //How many seconds between checking integer IsDay; Check() { vector sun_dir = llGetSunDirection(); //gets sun direction if (sun_dir.z > 0 && IsDay == FALSE) //a positive value for sun_dir.z means its daytime { IsDay = TRUE; //Do something here for when it is day. } else if (sun_dir.z < 0 && IsDay == TRUE) //a negative value for sun_dir.z means its nighttime { IsDay = FALSE; //Do something here for when it is night. } } default { on_rez(integer start_param) { llResetScript(); } state_entry() { vector sun_dir = llGetSunDirection(); IsDay = (sun_dir.z < 0); Check(); llSetTimerEvent(time); } timer() { Check(); //this calls the function to check the day / night status } touch_start(integer total_number) //only for debug - can be removed { Check(); if (IsDay == TRUE) { llSay(0, "It is currently day."); } else { llSay(0, "It is currently night."); } } }
