GlobalKeyword.Create

参数

返回

GlobalKeyword Returns a new instance of the GlobalKeyword class.

描述

Creates and returns a GlobalKeyword that represents a new or existing global shader keyword.

Unity creates and returns a GlobalKeyword struct to represent the global shader keyword with the given name. If a global shader keyword with the given name does not yet exist in Unity's internal list of global shader keywords, Unity adds a global shader keyword with the given name to the list.

The following example creates a GlobalKeyword struct with the name EXAMPLE_FEATURE_ON, and caches it. It provides functions to enable and disable it.

using UnityEngine;
using UnityEngine.Rendering;

public class GlobalKeywordExample : MonoBehaviour
{
    private GlobalKeyword exampleFeatureKeyword;

    private void Start()
    {
        exampleFeatureKeyword = GlobalKeyword.Create("EXAMPLE_FEATURE_ON");
    }

    public void EnableExampleFeature()
    {
        Shader.EnableKeyword(exampleFeatureKeyword);
    }

    public void DisableExampleFeature()
    {
        Shader.DisableKeyword(exampleFeatureKeyword);
    }
}
