[Solved]AngelScript function to generate geometry

Hello,

I want to write a script function, that will generate some custom geometry, something like this:

Geometry GustomGeom(uint16 param)
{
   Geometry@ geom = Geometry();  
   ...
   Do stuff, Generating and assigning vertex and index buffers
   ...
  
   return geom;
{

It does not work. I’ve tried returning Model type, I’ve tried to pass Model or Geometry as a parameter into void function, so it can do it’s stuff to it, but outcome is always the same:

[Mon Sep 07 03:31:12 2015] INFO: Scripts/game.as:117,1 Compiling void MakeObjects()
[Mon Sep 07 03:31:12 2015] ERROR: Scripts/game.as:124,13 No appropriate opAssign method found in 'Geometry' for value assignment

[Mon Sep 07 03:31:12 2015] ERROR: Failed to compile script module Scripts/game.as

I feel, I’m missing something essential.

Full code just in case:

[spoiler][code]
void MakeObjects()
{

Model@ rb_Model = Model();

Geometry geom = Ribbon(50);

rb_Model.numGeometries = 1;
rb_Model.SetGeometry(0, 0, geom);
rb_Model.boundingBox = BoundingBox(Vector3(-0.5, -0.5, -0.5), Vector3(0.5, 0.5, 0.5));

Node@ node = scene_.CreateChild(“rb_Model”);
node.position = Vector3(0.0, 0.0, 0.0);
StaticModel@ object = node.CreateComponent(“StaticModel”);
object.model = rb_Model;
}

Geometry Ribbon(uint16 numVertices)
{
Array vertexData(numVertices * 6, 0.0f);
Array indexData(numVertices);

for (uint16 i = 0; i<numVertices; ++i) vertexData[i] = Random();

for (uint16 i = 0; i<numVertices; ++i) indexData[i] = i;


VertexBuffer@ vb = VertexBuffer();
IndexBuffer@ ib = IndexBuffer();
Geometry@ geom = Geometry();

vb.shadowed = true;
vb.SetSize(numVertices, MASK_POSITION|MASK_NORMAL);
VectorBuffer temp;
for (uint i = 0; i < numVertices * 6; ++i)
    temp.WriteFloat(vertexData[i]);
vb.SetData(temp);

ib.shadowed = true;
ib.SetSize(numVertices, false);
temp.Clear();
for (uint i = 0; i < numVertices; ++i)
    temp.WriteUShort(indexData[i]);
ib.SetData(temp);

geom.SetVertexBuffer(0, vb);
geom.SetIndexBuffer(ib);
geom.SetDrawRange(TRIANGLE_LIST, 0, numVertices);

return geom;

}

Should be:

Daaaamn, shame I didn’t figured myself, to try that.

Thank you very much.
