Unity3d怎么用c#代码更改物体颜色

修改天空盒颜色的例子(C#)：

using UnityEngine

using System.Collections

public class example : MonoBehaviour {

public Color colorStart = Color.blue

public Color colorEnd = Color.green

public float duration = 1.0F

void Update() {

float lerp = Mathf.PingPong(Time.time, duration) /烂链吵 duration

RenderSettings.skybox.SetColor("_Tint", Color.Lerp(colorStart, colorEnd, lerp))

}

}

修改天空盒材质的例子(C#)：

// 加载所有 skybox 纹理

Texture2D sbFront = Resources.Load("Texture/Skybox/skybox_Front") as Texture2D

Texture2D sbBack = Resources.Load("Texture/Skybox/skybox_Back") as Texture2D

...

// 创建新饥侍的 SkyBox 材质

Material mySkyBoxMat = new Material(Resources.Load("Shaders/myOwnSkyboxShader") as Shader)

// 将所有纹理添加到材质中

mySkyBoxMat.SetTexture("_FrontTex", sbFront)

mySkyBoxMat.SetTexture("_BackTex", sbBack)

//唤拿 设置RenderSettings skybox 变量

RenderSettings.skybox = mySkyBoxMat

稍微完整些的例子(C#)：

using UnityEngine

using System.Collections

public class SkyboxSetter : MonoBehaviour

{

// 创建Skybox材质

public static Material CreateSkyboxMaterial(SkyboxManifest manifest)

{

Material result = new Material(Shader.Find("RenderFX/Skybox"))

result.SetTexture("_FrontTex", manifest.textures[0])

result.SetTexture("_BackTex", manifest.textures[1])

result.SetTexture("_LeftTex", manifest.textures[2])

result.SetTexture("_RightTex", manifest.textures[3])

result.SetTexture("_UpTex", manifest.textures[4])

result.SetTexture("_DownTex", manifest.textures[5])

return result

}

public Texture2D[] textures

void OnEnable()

{

SkyboxManifest manifest = new SkyboxManifest(textures[0], textures[1], textures[2], textures[3], textures[4], textures[5])

Material material = CreateSkyboxMaterial(manifest)

SetSkybox(material)

enabled = false

}

// 材质加到天空盒

void SetSkybox(Material material)

{

GameObject camera = Camera.main.gameObject

Skybox skybox = camera.GetComponent<Skybox>()

if (skybox == null)

skybox = camera.AddComponent<Skybox>()

skybox.material = material

}

}

public struct SkyboxManifest

{

public Texture2D[] textures

public SkyboxManifest(Texture2D front, Texture2D back, Texture2D left, Texture2D right, Texture2D up, Texture2D down)

{

textures = new Texture2D[6]

{

front,

back,

left,

right,

up,

down

}

}

}

代码测试结果：

按照RenderSettings.skybox = mySkyBoxMat方式设置并没有成功，用下面例子中的SetSkybox运行成功。

需要注意的是，Texture目录需要放在Resources目录下，最终的目录结构是这样的：

项目主目录/Assets/Resources/Textures/Skybox/skybox_Front.jpg

1.打开软件扒册，新建工程如下图所示。点击创建工程按钮。

2.在层级面板中穿件Cube，在项目面板鼠标右键中创建材质，如下图所示

3.在项目面板下创建脚本文件，如图所示

4.双击脚本文件打开，编写代乱此岁码如哗睁下

5.创建标准shader，如下图所示

6.并将创建的shader替换给Cube对象

7.双击打开5中创建的Shader文件，查看参数信息（参数信息的结果是为了书写4中的代码，参见经验视频）

8.将3中的脚本附加给Cube。

9.点击运行，结果如图。

新建一个c#文件，名称为Test，复制以下代码到文件里，然后拖到要凯罩变色的梁激物体上，运行，OK

using System.Collections

using System.Collections.Generic

using UnityEngine

public class Test : MonoBehaviour {

// Use this for initialization

void Start () {

}

// Update is called once per frame

void Update () {

GetComponent<橡孙袜Renderer>().material.color = Color.red

Debug.Log("我变红啦！")

}

}
