MeshFilter.mesh

Descripción

Retorna el Mesh instanciado asignado al mesh filter.

Si no hay un mesh asignado al mesh filter, un nuevo mesh será creado y asignado.

If a mesh is assigned to the mesh filter already, then first query of mesh property will create a duplicate of it, and this copy will be returned. Further queries of mesh property will return this duplicated mesh instance. Once mesh property is queried, link to the original shared mesh is lost and MeshFilter.sharedMesh property becomes an alias to mesh. If you want to avoid this automatic mesh duplication, use MeshFilter.sharedMesh instead.

By using mesh property you can modify the mesh for a single object only. The other objects that used the same mesh will not be modified.

It is your responsibility to destroy the automatically instantiated mesh when the game object is being destroyed. Resources.UnloadUnusedAssets also destroys the mesh but it is usually only called when loading a new level.

Considere la propiedad mesh como un atajo para el siguiente código:

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    void Start()
    {
        Mesh mesh = GetComponent<MeshFilter>().sharedMesh;
        Mesh mesh2 = Instantiate(mesh);
        GetComponent<MeshFilter>().sharedMesh = mesh2;
    }
}

Que se llama en la primera consulta de una propiedad mesh.

Note:
If MeshFilter is a part of an asset object, quering mesh property is not allowed and only asset mesh can be assigned.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    // Distorts the mesh vertically.
    void Update()
    {
        // Get instantiated mesh
        Mesh mesh = GetComponent<MeshFilter>().mesh;
        // Randomly change vertices
        Vector3[] vertices = mesh.vertices;
        int p = 0;
        while (p < vertices.Length)
        {
            vertices[p] += new Vector3(0, Random.Range(-0.3F, 0.3F), 0);
            p++;
        }
        mesh.vertices = vertices;
        mesh.RecalculateNormals();
    }
}
