drawing vertices

Questions & Answers

I'm drawing vertices in the editor as gizmo spheres however the positions are always stationary, never moving when I adjust the position or scale of the object it's attached to. Is there something I'm missing?

void OnDrawGizmosSelected () {

    MeshFilter selectedMeshFilter = (MeshFilter)gameObject.GetComponent("MeshFilter");
    Mesh mesh = selectedMeshFilter.mesh;
    Vector3[] vertices  = mesh.vertices;
    Color[] colors = new Color[vertices.Length];

    for (var i = 0  ; i < vertices.Length   ;   i++){

        Gizmos.DrawSphere (vertices*, vertexSize);*
 *}*
 *mesh.vertices = vertices;*
 *mesh.RecalculateBounds();*
*}*
*```*

Yes. The Transform component equates to a matrix that gets applied to vertex data. Changing values in the Transform will not update the vertices array of a mesh, nor would you want it to. Instead, use Matrix4x4.TRS, with the values from the Transform, and apply that to the vertices array that you get.
