Does the "success tolerance" of 0.1m hint that the function is for some reason prone to hitting with that wide an error, or is it just a very, very, very safe margin for a floating point roundoff of the requested location? | Does the "success tolerance" of 0.1m hint that the function is for some reason prone to hitting with that wide an error, or is it just a very, very, very safe margin for a floating point roundoff of the requested location? | ||

Does the "success tolerance" of 0.1m hint that the function is for some reason prone to hitting with that wide an error, or is it just a very, very, very safe margin for a floating point roundoff of the requested location? Tali Rosca 10:10, 3 March 2012 (PST)
The comment about warpPos is wrong
The error is <= 1e-6 .
( except of course if you try to go under the ground )
Tested on Linden Sandbox Magnum RC :
5000 llSetregionpos with random values ;
for z values < ground , we raise z;
Result : the 5000 llsetregionpos go to a correct position
<lsl>
default
{
touch_start(integer total_number)
{
integer numberTests = 5000 ;
integer n = 1;
vector d;
float h;
vector posTouched = llGetPos();
do
{
d = <llFrand(256.0), llFrand(256.0), llFrand(4096.0)>;
h = llGround(d-llGetPos());
if ( d.z <= h )
d.z = h + 1.0;
llSetRegionPos(d);
llOwnerSay(llList2CSV([ "test #", n, "error", llGetPos()-d, "pos",llGetPos(), "dest", d ]));
n++;
} while ( ((llGetPos()-d) == ZERO_VECTOR ) && ( n <= numberTests) ) ;
llSetRegionPos(posTouched);
}
}
