Shader.IsKeywordEnabled

参数

返回

bool Returns true if the given global shader keyword is enabled. Otherwise, returns false.

描述

Checks whether a global shader keyword is enabled for this material.

Shader keywords determine which shader variants Unity uses. For information on working with local and global shader keywords and how they interact, see Using shader keywords with C# scripts.

The following example checks the state of a global shader keyword called EXAMPLE_FEATURE_ON.

using UnityEngine;

public class Example : MonoBehaviour
{
    void Start()
    {
        if (Shader.IsKeywordEnabled("EXAMPLE_FEATURE_ON"))
        {
            Debug.Log("EXAMPLE_FEATURE_ON is enabled");
        }
    }
}
