[Closed] A simple question

I think you are looking for something like this:

(
local arraySize = [10,10,1]
local sphereRad = 1

for x = 1 to arraySize.x do (
[indent]for y = 1 to arraySize.y do (
[indent]for z = 1 to arraySize.z do (
[indent]local a = sphere radius:sphereRad
a.pos = [sphereRad * x,sphereRad * y,sphereRad * z]
 ) -- end of z loop
[/indent]) -- end of y loop
[/indent]) -- end of x loop
[/indent]) -- end of script

Thanks TzMtN, but I need a loop from 1 to 100,do you have any idea?

Why do you need a loop from 1 to 100?
you can devide the i by 10 to get the x value and use ‘mod i 10’ for the y value or something like that.

respect to you matan, an elegant recursive loop

Thanks TzMtN, you are right!

I agree it’s elegant, but how is it recursive?

I think he meant “nested” rather than “recursive”?

Great,I also found it in the SDK example, I need to rewrite it to c# code.There is also a problem if those Bezier Shapes come from two different nodes,Do we need to transform their corresponding matrix?

I rewrite them :

        int boff = shape.SplineCount;
        for (int i = 0; i < attShape.SplineCount; ++i)
        {
            int index = shape.SplineCount;
            ISpline3D spline = shape.NewSpline(0, 1, 0);
            spline = attShape.GetSpline(i);
            for (int seg = 0; seg < spline.Segments / 3; ++seg)
                spline.SetMatID(seg, (ushort)(spline.GetMatID(seg) + mtlOffset));
            shape.VertSel.Insert(shape.SplineCount - 1, spline.Verts);
            shape.SegSel.Insert(shape.SplineCount - 1, spline.Segments);
            shape.PolySel.Insert(shape.SplineCount - 1);
            shape.VertSel = attShape.VertSel;
            shape.SegSel = attShape.SegSel;
            shape.PolySel.Set(index, attShape.PolySel[i]);

            for (int j = 0; j < spline.KnotCount; ++j)
                spline.SetAux2(j, -1);
        }
        //copy over binds + offset
        for (uint i = 0; i < attShape.BindList.Length; i++)
        {
            attShape.BindList[i].PointSplineIndex += boff;
            attShape.BindList[i].SegSplineIndex += boff;


            shape.BindList.Append(attShape.BindList[i]);
        }
        for (uint i = 0; i < shape.BindList.Length; i++)
        {
            int index = 0;
            int spindex = shape.BindList[i].PointSplineIndex;
            if (shape.BindList[i].IsEnd)
                index = shape.GetSpline(spindex).KnotCount - 1;
            shape.BindList[i].BindPoint = shape.GetSpline(spindex).GetKnotPoint(index);
            shape.BindList[i].SegPoint = shape.GetSpline(spindex).GetKnotPoint(index);

        }

These are my test code:

                //spls is List<IINOde>
                IObject sobj = spls[0].ObjectRef;
                ISplineShape spl = (ISplineShape)sobj;
                IBezierShape bzSpl = spl.Shape;

                for (int i = 1; i < spls.Count; i++)
                {
                    ISplineShape nextspl = (ISplineShape)spls[i].ObjectRef;
                    SRYDoAttach(bzSpl, nextspl.Shape,0);
                 }
                bzSpl.UpdateSels(true);
                bzSpl.InvalidateGeomCache();

There is not any change for two splineshape s in my scene.Why?(using redraw views)
