Important: This page contains obsolete information and is kept only for historic purposes. The exploit that allowed this method to work was fixed in 2012. Use llSetRegionPos instead. |
Here's an interesting method for bypassing the 10m limitation in Non-Physical movement. Be aware that IT WILL NOT WORK FOREVER, there are plans to fix this bug - for long-term use, rely on warpPos. Alternatives that offer the same functionality are being considered. Until there's an alternative, this bug may be allowed to persist. More information here.
A replacement function llSetRegionPos() has been released and is now live grid-wide.
As of August 13th, 2012 there are already reported breakages of this function on some Channels.
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.
llSetLinkPrimitiveParamsFast(!!llGetLinkNumber(), [PRIM_POSITION, <1.304382E+19, 1.304382E+19, 0.0>, PRIM_POSITION, target_pos]);
}
//the !!llGetLinkNumber() thing is a little trick to always point to the root regardless of where the script is or whether the linkset got only one or more prims.
// If you are using a single prim object, you can substitute 0 or LINK_THIS. If it is a multiple prim object, you can substitute LINK_ROOT.
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 (just in case!) before trying the target position again. So in the case that the target position is no-entry, it will either move 10m at most, or not at all.
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();
llSetLinkPrimitiveParamsFast(!!llGetLinkNumber(), [PRIM_POSITION, <1.304382E+19, 1.304382E+19, 0.0>, PRIM_POSITION, target_pos, PRIM_POSITION, start_pos, PRIM_POSITION, target_pos]);
}
//the !!llGetLinkNumber() thing is a little trick to always point to the root regardless of where the script is or whether the linkset got only one or more prims.
// If you are using a single prim object, you can substitute 0 or LINK_THIS. If it is a multiple prim object, you can substitute LINK_ROOT.
