What wrong in this code? I’m try to get vertexes in current facet.

m_normIdx [4], m_uvwIdx [4] also don’t working :(

var oNode = Scene.getPrimarySelection();
if( oNode ){
var oObject = oNode.getObject();
var oShape = oObject.getCurrentShape();
var oGeometry = oShape.getGeometry();
var oFacet = oGeometry.getFacet(0);
for( k = 0; k < 4; k++ ) {
  var currentVertex = oGeometry.getVertex(oFacet.m_vertIdx[k]);
                                                                      ~~~~~~~~~~~~~~~
}
}

TypeError: Result of expression ‘oFacet.m_vertIdx’ [undefined] is not an object.

Edit - while I stand by my advice below, you should also check the type of oGeometry. I don’t see getFacet() in the DS 3 scripting docs, and I don’t see m_vertIdx as a member of any of the facet types which may be your biggest problem - it isn’t defined by you either.

—————————————————————————-

Try adding some error checking - I suspect you’re being too trusting and not ending up with a facet.

Same result with checking :(

Script Error: Line 12

From last SDK documentation:

file:
C:\Program Files\DAZ 3D\DAZStudio4 SDK\docs\class_dz_facet.html

DzFacet::m_vertIdx[4]
Array of vertex indices that make up the face. m_vertIdx[3] will be -1 if this is a triangle.

That’s the SDK, not the Scripting kit - they are not the same.

My fault

Whether there is a fresh version of Scripting kit? In DazStudio 4.5 it seems any more polygons, only triangles and quads are supported?

There are a couple of samples related to mesh generation, which isn’t of course what you are doing but it may be helpful:

You can also use Rob’s trick to see what members an object has:

Have you solved the problem yet?
Recently,my problem was how to add a single arrow to only one facet. Recently I installed a new version of R:

  platform i386-pc-mingw32
  version.string R version 2.14.2 (2012-02-29) ggplot2_0.9.0

Here is the code example
xdf <- data.frame(x=rep(1:10,each=4)
          ,y=rep(1:10,each=4)*rep(1:4,10)  +rnorm(40,0,1)
          ,g=rep(c(“R”,“S”),20)
          ,z=rep(c(“A”,“A”,“B”,“B”),10)
          )
head(xdf)
# plot
xp <- ggplot(xdf,aes(x=x,y=y, group=g)) +
geom_line() +
facet_grid(. ~ z)
xp
# location of the arrow: x=4, y=y+1 on the top of the first facet (A)
(f1x4 <- subset(xdf,x==4 & g==“R” & z==“A”)$y)
arrdf <- data.frame(x = 4, y = f1x4, z = “A”, g = “R”)  # create new data.frame for   annotations
# add arrow and label
xp + geom_segment(data=arrdf,aes(x=x,xend=x,y=y+3,yend=y,z=z,g=g)  # <—see the z=‘A’
          , arrow=arrow(length=unit(0.4,“cm”)
          )
        ) +
geom_text(data=arrdf,aes(x=x,y=y+4, label=“a”,z=z, g=g))
