integer link_number=llGetLinkNumber();
llSetLinkPrimitiveParams(link_number,[ PRIM_OMEGA ,<0,0,1>,0.1,PI]);
I used this scripts in the child prims only.then the child prims can rotate separately.But after I used this scripts in the root prim,the three objects rotate together and at the same time the child prims rotate by themself.I want to set the root prim to rotate separately too.How can I do?
