Strife Onizuka: bad assumption i think, llGetRootPosition i do not think includes the attachments local position (since the rot does not), pretty sure of this because attachment pos doesn't effect rez offset.

New page

While writing another function, I got thinking about the whole attachment local root rotation problem (you need to know the local rotation of the root prim in an attachment so you can use [[PRIM_ROT]]). I came to the conclusion with all the new(ish) functions, it is now possible to actually work this out.

# You know the position and rotation of the avatar, thanks to [[llGetObjectDetails]].
# You know the attach point ([[llGetAttached]])
# You know the combined rotation and position ([[llGetRootRotation]] & [[llGetRootPosition]])

It should just be a matter of subtracting the one from the other and canceling out the attach point offsets.

Something like this should work...

vector GetRootLocalPos()
{
integer point = llGetAttached();
if(point)
{
list avatar = llGetObjectDetails( llGetOwner(), [OBJECT_POS, OBJECT_ROT]);
return ((llList2Vector(avatar, 0) - llGetRootPosition()) / llList2Rot(avatar, 1)) / llList2Rot(offsets, point);
}
return llGetRootPosition();
}

vector GetRootLocalRot()
{
integer point = llGetAttached();
rotation root = llGetRootRotation();
if(point)
return ((root / llList2Rot(llGetObjectDetails( llGetOwner(), [OBJECT_ROT]), 0)) / llList2Rot(offsets, point);
return root;
