Shader.SetKeyword

切换到手册
public static void SetKeyword (ref Rendering.GlobalKeyword keyword, bool value);

参数

keyword The GlobalKeyword to enable or disable.
value The desired keyword state.

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); } }
