GetRegionTimeDilation

llGetRegionTimeDilation

Summary

Function: float llGetRegionTimeDilation( );

227	Function ID
0.0	Forced Delay
10.0	Energy

Returns a float that is the current time dilation, the value range is [0.0, 1.0], 0.0 (full dilation) and 1.0 (no dilation).^[1]

It is used as the ratio between the change of script time to that of real world time.

Specification

Time dilation is a method the server uses to cope with simulator lag. Physics and script generated lag can result in time dilation. Time dilation slows script time & execution. When time dilation is zero script execution halts.

Affects

• llGetTime & llGetAndResetTime
• Intervals of timer & sensor events queued as a result of llSetTimerEvent & llSensorRepeat.

Caveats

• Region idling lowers a region's framerate when no avatars are currently on or looking into the region. Scripts measuring time dilation with llGetRegionTimeDilation may report significant time dilation if the region is idle.

Examples

// The beginnings of a region-info script.
string region;
string sim;

default
{
    state_entry()
    {
        llSetTimerEvent(1.0);
    }
    timer()
    {
        string here = llGetRegionName();
        if(region != here)
        {
            sim = llGetSimulatorHostname();
            region = here;
        }
        llSetText(
                "   REGION NAME : " + region + 
              "\n  SIM HOSTNAME : " + sim + 
              "\n TIME DILATION : " + (string)llGetRegionTimeDilation() +
              "\n    REGION FPS : " + (string)llGetRegionFPS(),
            <0,1,0>, 1.0);
