[Opensim-users] npc and attachments

[paul emery]

Am wondering if anybody has some hints for simulating a bot picking up an
object carrying it some where and then putting it down. I have a kludge to
get the bot to bend over and "pick up" an object and carry it somewhere. I
cannot get him to drop the attachment. Here is my kludge.
             ...
                // appearance is a note card of bot without an attachment
                npc = osNpcCreate("Casias", "Twin", <104, 57, 27>,
"appearance");
                vector first = osNpcGetPos(npc);
                vector second = first + <6,0,0> ;
                llOwnerSay("I am going to get it. ");
                //osNpcMoveToTarget(npc, llGetPos() + <2,0,0>,
OS_NPC_NO_FLY); 
                osNpcMoveToTarget(npc, second, OS_NPC_NO_FLY); 
                llSleep(5);
                llOwnerSay("I am picking it up.");
                osAvatarPlayAnimation(npc, "Casbow");
                osNpcLoadAppearance(npc,"carry"); 
// replaced the bot appearance from a second notecare that includes the item
attached to chest
                llSleep(5);
                vector xyz_angles = <0,0,180>; // This is to define a 45
degree change
                vector angles_in_radians = xyz_angles * DEG_TO_RAD; //
Change to Radians
                rotation rot_xyzq = llEuler2Rot(angles_in_radians); //
Change to a Rotation                
                rotation rot = osNpcGetRot(npc);
                osNpcSetRot(npc, rot * rot_xyzq);
                //osNpcMoveToTarget(npc, llGetPos() - <2,0,0>,
OS_NPC_NO_FLY);  
                llOwnerSay("returning");
                osNpcMoveToTarget(npc,first, OS_NPC_NO_FLY);
                llSleep(5);
                llOwnerSay("I am putting it down.");
                osAvatarPlayAnimation(npc, "Casbow"); 
                llSleep(5);    
                // i thought going back to original notecard appearance
would get rid of the attachment
                // but it doesn't. So really bad kludge             
                osNpcRemove (npc);
                llOwnerSay("should have disappeared");
                npc = osNpcCreate("Casias", "Twin", <104, 57, 27>,
"appearance");

Ok now don't laugh just give me some suggestions
