Wiki description

Instantiate inventory object rotated to rot with its root at position, moving at velocity, using param as the start parameter

Function notes

To rez an object so its center is at position (instead of the root) use llRezObject instead.

Caveats

• Silently fails to rez inventory if position is more than 10 meters away from the prim trying to rez inventory. (Note: the max distance is actually 10.0 + llVecMag(llGetScale()/2))
• If the object is unattached and the owner of the object does not have copy permission on inventory, the object will no longer be present in inventory after it is rezzed (so another attempt to rez (the same object) will fail); if the owner does have copy permission, then a copy is rezzed, and the original inventory remains in inventory.
• If the object is attached and the owner of the object does not have copy permission on inventory, an error is shouted on DEBUG_CHANNEL: "Cannot rez no copy objects from an attached object."
• Silently fails if you don't have offline building rights on the land. To have the right, your objects needs to either:
  • Be on land you own yourself.
  • Be on land where anyone is allowed to build, e.g. a sandbox.
  • Be deeded to the group that owns the land.
  • Be set to the same group that owns the land and the land have the parcel flag 'allow group to build' set.
• The group role "Always allow 'Create Objects'" will only work to override this when you are online, in the region, or have a child agent in the region. See the issues under Deep Notes for more information.
• See object_rez for examples on how to establish communications between the rezzing object and the new prim.

Examples

//Rez an object on touch
string object = "Object";//Object in inventory
integer start_param = 10;
rotation rot;

default
{
    state_entry()
    {
        rot = llEuler2Rot(< 0, 90, 90> * DEG_TO_RAD);
    }
    touch_start(integer a)
    {
        vector vec = llGetPos() + < 0.0, 0.0, 5.0>; // 5 meter above this
        vector speed = llGetVel();
        llRezAtRoot(object, vec, speed, rot, start_param);
    }
}

//Rez an object on touch, with relative position, rotation, and velocity all described in the rezzing prim's coordinate system.
string object = "Object"; // Name of object in inventory
vector relativePosOffset = <2.0, 0.0, 1.0>; // "Forward" and a little "above" this prim
vector relativeVel = <1.0, 0.0, 0.0>; // Traveling in this prim's "forward" direction at 1m/s
rotation relativeRot = <0.707107, 0.0, 0.0, 0.707107>; // Rotated 90 degrees on the x-axis compared to this prim
integer startParam = 10;

default
{
    touch_start(integer a)
    {
        vector myPos = llGetPos();
        rotation myRot = llGetRot();

        vector rezPos = myPos+relativePosOffset*myRot;
        vector rezVel = relativeVel*myRot;
        rotation rezRot = relativeRot*myRot;

        llRezAtRoot(object, rezPos, rezVel, rezRot, startParam);
    }
}

Template:LSL Function/position

Original shared helper source (conditional wiki logic is not evaluated)

{{LSL Injection Test}}<noinclude>
This template is to be used to specify setup the description for position like parameters (offsets, positions, points, etc.).

Right now it's pretty basic and easy to edit. I'm wondering if these functions should be in a position parameter specific category.

====TODO====
