Material.SetColor

参数

描述

Sets a color value.

许多着色器使用多种颜色。使用 SetColor 可更改颜色（由着色器属性名称或唯一的属性名称 ID 标识）。

使用标准着色器对材质设置颜色值时应该知道，可能需要使用 EnableKeyword 启用以前未使用的着色器功能。有关更多详细信息，请参阅Accessing Materials via Script。

Unity 内置着色器使用的常用颜色名称：\ "_Color" 是材质的主色。它还可以通过 color 属性进行访问。\ "_EmissionColor" 是材质的发光颜色。

//Attach this script to any GameObject in your scene to spawn a cube and change the material color
using UnityEngine;

public class Example : MonoBehaviour
{
   void Start()
   {
       // Create a new cube primitive to set the color on
       GameObject cube = GameObject.CreatePrimitive(PrimitiveType.Cube);

       // Get the Renderer component from the new cube
       var cubeRenderer = cube.GetComponent<Renderer>();

       // Call SetColor using the shader property name "_Color" and setting the color to red
       cubeRenderer.material.SetColor("_Color", Color.red);
   }
}

//Attach this script to any GameObject in your scene to spawn a cube and change the material color to a custom color
using UnityEngine;

public class Example : MonoBehaviour
{
   void Start()
   {
       // Create a new cube primitive to set the color on
       GameObject cube = GameObject.CreatePrimitive(PrimitiveType.Cube);

       // Get the Renderer component from the new cube
       var cubeRenderer = cube.GetComponent<Renderer>();

        // Create a new RGBA color using the Color constructor and store it in a variable
        Color customColor = new Color(0.4f, 0.9f, 0.7f, 1.0f);

       // Call SetColor using the shader property name "_Color" and setting the color to the custom color you created
       cubeRenderer.material.SetColor("_Color", customColor);
   }
