Summary

Function: llSetPos( vector pos );

Moves the object or primitive towards pos without using physics.

• vector pos position in region or local coordinates depending upon the situation (see #Specification).

Movement is capped to 10m per call for unattached root prims.[1]

Specification

This function is available for nonphysical root prims and all child prims. It has no effect on the root prim if the object is physical.

Coordinate Frame

Caveats

  • This function causes the script to sleep for 0.2 seconds.
  • Because of the intermixing of local and regional coordinates with this function, when a prims position is wanted it is best to use llGetLocalPos.
  • This function does not work in the root prim of physical objects. Use a physical function like llMoveToTarget instead.
  • If you have explicitally set your object as "static obstacle" for pathfinding , the function will fail with the error in the debug channel:
    • "Unable to set prim position or scale: object contributes to the navmesh."

Examples

//Move the object up 1m when someone touches it.

     touch_start(integer i) {
          llSetPos(llGetPos() + <0,0,1>);
     }

llSetLocalPos(vector offset)
{
    vector save = offset;
    if(offset.x < 0.0) offset.x -= 1;
    else offset.x += 1;
    if(offset.y < 0.0) offset.y -= 1;
    else offset.y += 1;
    if(offset.z < 0.0) offset.z -= 1;
    else offset.z += 1;
    llSetPos(offset);
    llSetPos(save);    
}

Notes

Multiple movement commands can be chained together with llSetPrimitiveParams and PRIM_POSITION. The advantage of doing this is that the script only sleeps once per function call instead of once per movement.
