Mesh.MeshDataArray.Dispose

描述

Use this method to dispose of the MeshDataArray struct.

It is important to dispose of a MeshDataArray struct once you have finished working with it. Modifying a Mesh while a MeshDataArray struct for that Mesh exists results in memory allocations and data copies. Use Dispose to dispose of the MeshDataArray struct when you have finished using it, or use the C# using pattern to do this automatically:

using Unity.Collections;
using UnityEngine;
public class ExampleScript : MonoBehaviour
{
    void Start()
    {
        var mesh = new Mesh();
        mesh.vertices = new[] {Vector3.one, Vector3.zero};
        using (var dataArray = Mesh.AcquireReadOnlyMeshData(mesh))
        {
            // prints "2"
            Debug.Log(dataArray[0].vertexCount);
        }
    }
}
