Here's an interesting method for bypassing the 10m limitation in Non-Physical movement. It has its similarities to warpPos, but with minimal overhead.
<lsl> posJump(vector target_pos) { // An alternative to the warpPos trick without all the overhead. // Trickery discovered by Uchi Desmoulins and Gonta Maltz. More exact value provided by Fake Fitzgerald. llSetPrimitiveParams([PRIM_POSITION, <1.304382E+19, 1.304382E+19, 0.0>, PRIM_POSITION, target_pos]); } </lsl>
If the target position turns out to be no-entry, your object will go offworld. So Alias Turbo included a step that sends the object back to its starting position before trying the target position again. So if it can't enter the target position, it doesn't move at all.
<lsl>
safe_posJump(vector target_pos)
{
// An alternative to the warpPos trick without all the overhead.
// Trickery discovered by Uchi Desmoulins and Gonta Maltz. More exact value provided by Fake Fitzgerald. Safe movement modification provided by Alias Turbo.
vector start_pos = llGetPos();
llSetPrimitiveParams([PRIM_POSITION, <1.304382E+19, 1.304382E+19, 0.0>, PRIM_POSITION, target_pos, PRIM_POSITION, start_pos, PRIM_POSITION, target_pos]); } </lsl>
Don't rely on this behavior without first discussing it with a Physics Linden. It's certainly a bug, and likely to be fixed.
