llSetLinkPrimitiveParamsFast Calcs

[Creative Starfall]

Hi:

Can you please help with these calculations?

Quote

 

vector localPos = <0.13982,-0.02822,1.79004>;
vector localRot = <0,0,22>;

vector AdjustPos = <0.0,0.0,0.5>;
vector AdjustRot = <0.0,0.0,-6.05>;

HOW TO MAKE THESE CALCULATIONS? <-------------
setLocalPos = localPos - AdjustPos;
setLocalRot = localRot - AdjustRot;

llSetLinkPrimitiveParamsFast(linkNr, [PRIM_POS_LOCAL, setLocalPos, PRIM_ROT_LOCAL, setLocalRot]);

 

Thank you!

Well, first use legitimate rotations.  The values you are using are all vectors.  So, either replace them with rotations or use llEuler2Rot to convert them.

Ty for reply Rolig!

 

Can you please tell me if this code is ok?

            vector t_Pos = (((llList2Vector(PosInit, i)-llList2Vector(AdjP, i))-llGetRootPosition())) / llGetRootRotation();
            t_Pos = llGetRootPosition() + t_Pos * llGetRootRotation();
            
            rotation childRot = llEuler2Rot(llList2Vector(RotInit, i) * DEG_TO_RAD) / llEuler2Rot(llList2Vector(AdjR, i) * DEG_TO_RAD);
            rotation t_Rot = childRot / llGetRootRotation();
            t_Rot = t_Rot * llGetRootRotation();

            llSetLinkPrimitiveParamsFast(llList2Integer(BDLnk, i), [PRIM_POS_LOCAL, t_Pos, PRIM_ROT_LOCAL, t_Rot]);

 

I'm not sure about / or * signs!

It looks reasonable, although you should be using llGetRot instead of llGetRootRot.  The best way to find out whether it is doing what you hope is to try it out and see.  In the end, that's the test you want to satisfy
