Hi,

In new to away3d, i like to ask, if there’s a way to trace or get the background color of my mesh object?
Kindly refer on my code below. Thanx.

case AssetType.MESH:
    _mesh = new Mesh();
    _mesh = evt.asset as Mesh;
    _mesh.mouseEnabled = true;
    _mesh.addEventListener(MouseEvent3D.CLICK, onMouseClick);
    _mesh.addEventListener(MouseEvent3D.MOUSE_OUT, onMouseOut);
    _mesh.addEventListener(MouseEvent3D.MOUSE_OVER, onMouseOver);

    trace("Mesh: " + _mesh.name);
    trace("Submesh:" + _mesh.subMeshes.length);
    
    for each(var sg:SubGeometry in _mesh.geometry.subGeometries)
    {
     sg.autoDeriveVertexNormals = true;
     sg.autoDeriveVertexTangents = true;
    }
    
    for each(var sm:SubMesh in _mesh.subMeshes)
    {
     _material = new ColorMaterial(0xFFFFFF * Math.random());
     
     sm.material = _material;
     _mesh.material = _material;
     
     sm.material.lightPicker = _staticLightPicker;
    }
   break;

What do you mean by the “background color” of your mesh? You are configuring your material to be randomly colored, so your code is already controlling the color. Isn’t that the color that you’re after?

I have a MouseEvent3D, that when i click the specific mesh on the stage. I want to get the backgroundColor value in hexadecimal format.

For example.

When i click the cellphone Mesh object with white background Color.
I want to trace the color of if and show on my output tab. “0xFFFFFF”.
Hope you can help me.

Thanx,

Best Regards,
Josh

Listen for a mouse event, when the event fires, cast the event.currentTarget object to a Mesh, and cast it’s material to a ColorMaterial, and retrieve the color property from there.

myMesh.addEventListener(MouseEvent3D.CLICK, onClick);

function onClick(ev : MouseEvent3D) : void
{
  var mesh : Mesh = Mesh(ev.currentTarget);
  var mat : ColorMaterial = ColorMaterial(mesh.material);
  trace(mat.color);
} 

The color property contains the numeric representation of the color (i.e. the hexadecimal value that you passed into your material constructor). If you really care about it being a hexadecimal string representation, you can use Number.toString() for that.
