Hi Niko.
Can you please point me on how can i change the scale of TCoords.X,TCoords.Y in a meshbuffer?
I am doing this but it doesn't work.

var SelMesh = SomeMesh.getMesh();
if (SelMesh)
{
var meshBuffer = SelMesh.GetMeshBuffers();
if (meshBuffer)
{
for (var j = 0; j < meshBuffer.length; j++)
{
var BufVertices = meshBuffer[j].Vertices;
for (var k = 0; k < BufVertices.length; k++ )
{
meshBuffer[j].Vertices[k].TCoords.X = 10;
meshBuffer[j].Vertices[k].TCoords.Y = 10;
}
meshBuffer[j].Mat.Tex1 = engine.getTextureManager().getTexture("Image.jpg", true);
}
}

}

Thank's

Scaling is done by multiplying, so your code should probably something like this:


var yourScale = 2.0; // scale by 2
...

meshBuffer[j].Vertices[k].TCoords.X *= yourScale;
meshBuffer[j].Vertices[k].TCoords.Y *= yourScale;

It doesn't work can you please check it out?
And the other post i had about cloning a mesh bug did you checked it?

Thank's

Should work, you probably forgot to call update() at the meshbuffer after you finished your modifications?
Cloning meshes should be fixed with the next update.

It's not working i called the update() and when i alert(meshBuffer[j].Vertices[k].TCoords.X ) it prints the right number (10) but it doesn't update the scale?????
