Try this method instead.
var mesh:Mesh = gameGrid.getChildByName(e.object.name) as Mesh;
for each(face:Face in mesh.faces)
{
face.material = new WireColorMaterial(0xFF0000, {alpha:0.2,
wireColor:0xFFFFFF, thickness:3});
}
With this you're getting the cell you want selected, and then no
matter how many faces you put inside the object, you'll update them
all.
I don't think you'll need to assign an entirely new material either so
trying something like:
WireColorMaterial(face.material).color = 0xFF0000;
That is if all you're looking for is to change the color, can do the
same way with other properties.
