public void SetColor (string name, Color value);
public void SetColor (int nameID, Color value);

参数

nameID 属性名称 ID,使用 Shader.PropertyToID 获取。
name Property name. For example, "_Color" in Built-in Render Pipeline, "_BaseColor" in URP.
value 要设置的颜色值。

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

Color property names are defined in the Properties section in the shader code. Here are examples of the color properties in Unity pre-built shaders:
_Color: the main color of a material (URP: _BaseColor). You can access this shader property via the color property.
_EmissionColor: the emissive color of a material.

//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>();

// Use SetColor to set the main color shader property cubeRenderer.material.SetColor("_Color", Color.red); // If your project uses URP, uncomment the following line and use it instead of the previous line // cubeRenderer.material.SetColor("_BaseColor", Color.red); } }
