function Clear () : void

Description

Clears all vertex data and all triangle indices.

You should call this function before rebuilding triangles array.

JavaScripts
// Draws a simple triangle with UVs

function Start () {
gameObject.AddComponent("MeshFilter");
gameObject.AddComponent("MeshRenderer");
var mesh : Mesh = GetComponent(MeshFilter).mesh;

// Clears all the data that the mesh can contain previously.
mesh.Clear();

mesh.vertices = [Vector3(0,0,0), Vector3(0,1,0), Vector3(1, 1, 0)];
mesh.uv = [Vector2 (0, 0), Vector2 (0, 1), Vector2 (1, 1)];
mesh.triangles = [0, 1, 2];
}
