Its expecting object.pnt[#s array] and only constant strings part should
be inside quotes, vars should be outside.
//piece of lightrig:
var oLightRig = activesceneroot.addlightrig( "Spot.Preset",
"Spot_Root");
oLightRig.light.posx = 5
oLightRig.light.posy = 5
oLightRig.light.posz = 5
var oCurve = createcurve( 1, 0, "(0,0,0),(5,5,5)", false )(0);
oLightRig.addchild( oCurve );
logmessage(oCurve.activeprimitive.geometry.points(0).index);
var cc = ApplyOp("ClusterCenter",
oCurve+".pnt["+oCurve.activeprimitive.geometry.points(0).index+"];"+oLig
htRig.light.interest , 3, siPersistentOperation,null);
var cc2 = ApplyOp("ClusterCenter",
oCurve+".pnt["+(oCurve.activeprimitive.geometry.points.count-1 (See http://unt-1.ora-code.com))+"];"+oLi
ghtRig.light , 3, siPersistentOperation,null);
//access and use egs:
logmessage(cc(0).posy);
logmessage(cc2(0).posy);
SetKey(oLightRig.light.posx, 0, 10, null);
SetKey(oLightRig.light.posx, 10, 20, null);
