      public void compile(ShaderCompiler.Context context, ShaderCompiler compiler) throws Exception
      Description copied from interface: ShaderProgram
      Compiles this shader based on the specified definition.
      Specified by:
      compile in interface ShaderProgram
      Parameters:
      context - The context to use when compiling shaders

      Exception - If an error occurs while compiling or linking shaders

    • free

      public void free()
      Specified by:
      free in interface org.lwjgl.system.NativeResource

    • getShaders

      public it.unimi.dsi.fastutil.ints.Int2ObjectMap<CompiledShader> getShaders()
      Specified by:
      getShaders in interface ShaderProgram
      Returns:
      The shaders attached to this program

    • getDefinitionDependencies

      public Set<String> getDefinitionDependencies()
      Specified by:
      getDefinitionDependencies in interface ShaderProgram
      Returns:
      All shader definitions this program depends on

    • getId

      public net.minecraft.resources.ResourceLocation getId()
      Specified by:
      getId in interface ShaderProgram
      Returns:
      The id of this program

    • toShaderInstance

      public ShaderProgramImpl.Wrapper toShaderInstance()
      Description copied from interface: ShaderProgram

      Wraps this shader with a vanilla Minecraft shader instance wrapper. There are a few special properties about the shader wrapper.

      • The shader instance cannot be used to free the shader program. NativeResource.free() must be called separately. If the shader is loaded through ShaderManager then there is no need to free the shader.
      • Calling Uniform.upload() will do nothing since the values are uploaded when the appropriate methods are called
      • Uniforms are lazily wrapped and will not crash when the wrong method is called.
      • Uniform.set(int, float) is not supported and will throw an UnsupportedOperationException.
      • Only Uniform.set(Matrix3f) and Uniform.set(Matrix4f) will be able to set matrix values. All other matrix methods will throw an UnsupportedOperationException.
      • Uniform.set(float[]) only works for 1, 2, 3, and 4 float elements. Any other size will throw an UnsupportedOperationException.
      Specified by:
      toShaderInstance in interface ShaderProgram
      Returns:
      A lazily loaded shader instance wrapper for this program
