Material.mainTexture

描述

主纹理。

By default, Unity considers a texture with the property name name "_MainTex" to be the main texture. Use the [MainTexture] ShaderLab Properties attribute to make Unity consider a texture with a different property name to be the main texture. When the main texture is set using the [MainTexture] attribute, it is not visible in the Game view when you use the texture streaming debugging view mode or a custom debug tool.

这与调用将主纹理属性名称作为参数的 Material.GetTexture 或 Material.SetTexture 相同。

另请参阅：SetTexture、GetTexture、ShaderLab：属性、ShaderPropertyFlags.MainTexture。

// Change main texture each changeInterval/
// seconds from the texture array defined in the inspector.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    public Texture[] textures;
    public float changeInterval = 0.33F;
    public Renderer rend;

    void Start()
    {
        rend = GetComponent<Renderer>();
    }

    void Update()
    {
        if (textures.Length == 0)
            return;

        int index = Mathf.FloorToInt(Time.time / changeInterval);
        index = index % textures.Length;
        rend.material.mainTexture = textures[index];
    }
