Shader.SetKeyword

参数

描述

Sets the state of a global shader keyword.

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

When value is true, this function calls EnableKeyword. Otherwise, it calls DisableKeyword.

The following example creates and caches a GlobalKeyword, and provides a function to toggle its state.

using UnityEngine;
using UnityEngine.Rendering;

public class GlobalKeywordExample : MonoBehaviour
{
    private GlobalKeyword exampleFeatureKeyword;

    private void Start()
    {
        // Create and cache the GlobalKeyword
        exampleFeatureKeyword = GlobalKeyword.Create("EXAMPLE_FEATURE_ON");
    }

    public void ToggleExampleFeature()
    {
        // Get the current state of the global keyword
        bool state = Shader.IsKeywordEnabled(exampleFeatureKeyword);

        // Toggle the state
        Shader.SetKeyword(exampleFeatureKeyword, !state);
    }
}
