public Rendering.LocalKeywordSpace keywordSpace ;

説明

The local keyword space of this compute shader.

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.

keywordSpace represents all keywords declared in the source file for a compute shader. For information about declaring and using shader keywords in shader source files, see Shader keywords.

This example iterates over the local shader keywords in the local keyword space for a compute shader. It determines whether they are overridden by a global shader keyword, and prints their state.

using UnityEngine;
using UnityEngine.Rendering;

public class Example : MonoBehaviour { public ComputeShader computeShader;

void Start() { CheckShaderKeywordState(); }

void CheckShaderKeywordState() { // Get all the local keywords that affect the Compute Shader var keywordSpace = computeShader.keywordSpace;

// Iterate over the local keywords foreach (var localKeyword in keywordSpace.keywords) { // If the local keyword is overridable, // and a global keyword with the same name exists and is enabled, // then Unity uses the global keyword state if (localKeyword.isOverridable && Shader.IsKeywordEnabled(localKeyword.name)) { Debug.Log("Local keyword with name of " + localKeyword.name + " is overridden by a global keyword, and is enabled"); } // Otherwise, Unity uses the local keyword state else { var state = computeShader.IsKeywordEnabled(localKeyword) ? "enabled" : "disabled"; Debug.Log("Local keyword with name of " + localKeyword.name + " is " + state); } } } }
