MESH

Meshes terdiri atas vertices dan triangle arrays. Triangle arrays diindeks dalam array vertex. Tiga index untuk setiap triangle. Untuk setiap vertex terdiri atas normal, koordinat dua texture, warna, dan tangent, ini opsional dan dapat dihilangkan jika diinginkan. Semua informasi vertex disimpan dalam array terpisah pada ukuran yang sama, jadi jika sebuah mesh memiliki 10 verticesmaka kita juga akan memiliki array berukuran 10 untuk normal dan atribut lain. Ada 3 kemungkinan terhadap mofidikasi sebuah mesh.

a.) Membuat sebuah mesh dari awal

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    public Vector3[] newVertices;
    public Vector2[] newUV;
    public int[] newTriangles;
    void Start() {
        Mesh mesh = new Mesh();
        GetComponent<MeshFilter>().mesh = mesh;
        mesh.vertices = newVertices;
        mesh.uv = newUV;
        mesh.triangles = newTriangles;
    }
}

b.) Memodikasi atribut vertex setiap frame

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    void Update() {
        Mesh mesh = GetComponent<MeshFilter>().mesh;
        Vector3[] vertices = mesh.vertices;
        Vector3[] normals = mesh.normals;
        int i = 0;
        while (i < vertices.Length) {
            vertices[i] += normals[i] * Mathf.Sin(Time.time);
            i++;
        }
        mesh.vertices = vertices;
    }
}

c.) Merubah mesh triangle dan vertices terus menerus

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    public Vector3[] newVertices;
    public Vector2[] newUV;
    public int[] newTriangles;
    void Update() {
        Mesh mesh = GetComponent<MeshFilter>().mesh;
        mesh.Clear();
        mesh.vertices = newVertices;
        mesh.uv = newUV;
        mesh.triangles = newTriangles;
    }
}

Variables

bindposes	The bind poses. The bind pose at each index refers to the bone with the same index.
blendShapeCount	Returns BlendShape count on this mesh.
boneWeights	The bone weights of each vertex.
bounds	The bounding volume of the mesh.
colors	Vertex colors of the mesh.
colors32	Vertex colors of the mesh.
isReadable	Returns state of the Read/Write Enabled checkbox when model was imported.
normals	The normals of the mesh.
subMeshCount	The number of submeshes. Every material has a separate triangle list.
tangents	The tangents of the mesh.
triangles	An array containing all triangles in the mesh.
uv	The base texture coordinates of the mesh.
uv2	The second texture coordinate set of the mesh, if present.
vertexCount	Returns the number of vertices in the mesh (Read Only).
vertices	Returns a copy of the vertex positions or assigns a new vertex positions array.

Constructors

Mesh	Creates an empty mesh.

Functions

Clear	Clears all vertex data and all triangle indices.
CombineMeshes	Combines several meshes into this mesh.
GetBlendShapeName	Returns name of BlendShape by given index.
GetIndices	Returns the index buffer for the submesh.
GetTopology	Gets the topology of a submesh.
GetTriangles	Returns the triangle list for the submesh.
MarkDynamic	Optimize mesh for frequent updates.
Optimize	Optimizes the mesh for display.
RecalculateBounds	Recalculate the bounding volume of the mesh from the vertices.
RecalculateNormals	Recalculates the normals of the mesh from the triangles and vertices.
SetIndices	Sets the index buffer for the submesh.
SetTriangles	Sets the triangle list for the submesh.

Inherited members

Variables

hideFlags	Should the object be hidden, saved with the scene or modifiable by the user?
name	The name of the object.

Functions

GetInstanceID	Returns the instance id of the object.
ToString	Returns the name of the game object.

Static Functions

Destroy	Removes a gameobject, component or asset.
DestroyImmediate	Destroys the object obj immediately. You are strongly recommended to use Destroy instead.
DontDestroyOnLoad	Makes the object target not be destroyed automatically when loading a new scene.
FindObjectOfType	Returns the first active loaded object of Type type.
FindObjectsOfType	Returns a list of all active loaded objects of Type type.
Instantiate	Clones the object original and returns the clone.

Operators

bool	Does the object exist?
operator !=	Compares if two objects refer to a different object.
operator ==	Compares if two objects refer to the same.
