This is a script that has been painstakingly crafted by Nexii Malthus to create a highly efficient and advanced system of controlling a large linkset of prims in a parametric fashion of a mechanical structure or robotic limb. I am giving out this script to the people now, to me it is a huge contribution to the community as I have spent many weeks designing the plans and debugging the script as well as studying and researching efficient script design. This can be used in your product under the condition you put credit in a visible location to the consumer that you used my work or derived from my work.


Simple Example: Create a prim and shift-drag to create a tower of 4 prims. Name 3 of them as following, from top to bottom 

A.B.C
A.B
A

Link them all up so the 4th unnamed prim is the root object, which should be the last prim on the bottom as a base.

Drop the Hierarchics script into each of the named prims.

Create a new script in the root object. Put the following constants as globals. <lsl> integer Link_HierarchicsRot = 660333; rotation LastQuatA; rotation LastQuatB; </lsl>

In the touch_start event, put the following. <lsl> 

   rotation QuatA = llEuler2Rot( < 0, 0, 15 > * DEG_TO_RAD ) * LastQuatA;
   rotation QuatB = llEuler2Rot( < 5, 0, 0 > * DEG_TO_RAD ) * LastQuatB;
   llMessageLinked(LINK_SET, Link_HierarchicsRot, (string)QuatA+";"+(string)QuatB, "A;A.B" );
   LastQuatA = QuatA;
   LastQuatB = QuatB;

</lsl>

Keep touching and observe the prims following their commanded rotations.
