RezAtRoot

llRezAtRoot

Summary

1 Bug

Function: llRezAtRoot( string inventory, vector position, vector velocity, rotation rot, integer param );

0.1	Forced Delay
200.0	Energy

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

• string	inventory	–	an object in the inventory of the prim this script is in
• vector	position	–	position in region coordinates to place the object
• vector	velocity	–	initial velocity
• rotation	rot	–	initial rotation
• integer	param	–	on_rez event parameter and value returned by llGetStartParameter in the rezzed object (or by each of the items in a coalesced object).

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

Caveats

• This function causes the script to sleep for 0.1 seconds.
• If inventory is missing from the prim's inventory or it is not an object then an error is shouted on DEBUG_CHANNEL.
• 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);
    }
}

/* 
    NO COPY Rezzer Example by Daemonika Nightfire
    Always rez the first object at touch, removing it from the content,
    when the first one is removed, the next object automatically moves to the first position.

    Content example:
    object (no copy)
    object 1 (no copy)
    object 2 (no copy)
    object 3 (no copy)
    object 4 (no copy)
    ...
