通行证

Specifies shaders and their defines to be used during the specific pass. The shaders are compiled for the specified render pass using the defines specified in attributes.指定要在特定通道期间使用的着色器及其定义。使用属性中指定的定义为指定的渲染通道编译着色器。

The syntax is the following:语法如下:

ULON
Pass render_pass_name
{
	Vertex = deferred_shader
	Fragment = deferred_shader
}
注意
You can specify various types of shaders in the pass (see the list of available shaders in UNIGINE).您可以在通道中指定各种类型的着色器 (见清单UNIGINE 中可用的着色器)。

You can check the current pass in the shader using the following defines:您可以使用以下定义检查着色器中的当前通道:

UUSL
PASS_<pass name>

Types of Passes通行证类型#

  • refractionrefraction passrefraction - refraction 通行证
  • reflectionreflection passreflection - reflection 通行证
  • transparent_blurtransparent blur passtransparent_blur - transparent blur 通行证

Usage Examples使用示例#

ULON
Pass deferred 
{
	Vertex = deferred_shader
	Fragment = deferred_shader
}
	
Pass shadow 
{
	Vertex = deferred_shader
	Fragment = deferred_shader
}

Pass depth_pre_pass 
{
	Vertex = depth_pre_pass_shader
	Fragment = depth_pre_pass_shader
}
	
Pass ms_depth 
{
	Vertex = depth_pre_pass_shader
	Fragment = depth_pre_pass_shader
}
注意
If the vertex shader isn't specified, the default core/shaders/common/empty.vert shader will be used.如果未指定顶点着色器,将使用默认的 core/shaders/common/empty.vert 着色器。

Besides the shader node you can specify the relative path (as a string) to the file containing shader code in UUSL:除了着色器节点,您还可以在 UUSL 中指定包含着色器代码的文件的相对路径(作为字符串):

ULON
Pass lightmap_data
{
	Vertex = "core/shaders/mesh/lightmap_data.shader"
	Fragment = "core/shaders/mesh/lightmap_data.shader"
}

It is also possible to write inline shaders inside the Pass node (put them inside the #{ … }# construct):也可以在Pass节点内编写内联着色器(将它们放在 #{ … }# 构造中):

ULON
Pass name
{
	Geometry = 
	#{
		// UUSL code
	}#
}

Arguments论据#

definesdefines#

String

Definitions that will be passed to the shader.将传递给着色器的定义。

Usage Example:使用示例:

ULON
defines="MY_DEFINE=32,MY_DEFINE_2"
注意
You can list multiple defines separated by a comma without any space. To specify a value for a define, write the value after the equals sign symbol.您可以列出多个用逗号分隔的定义,不带任何空格。要为定义指定一个值,请将值写在等号符号之后。

nodenode#

String

Specifies the type of a node for which this pass will be used (by default - all node types).指定将使用此通道的节点的类型(默认情况下 - 所有节点类型)。

Available values:可用值:

Usage Example使用示例#

ULON
Pass ambient <defines="BOX,HEIGHT" node=ObjectVolumeBox>
{
	Vertex = volume_shader
	Fragment = volume_shader
}

Pass ambient <defines="SPHERE,HEIGHT" node=ObjectVolumeSphere>
{
	Vertex = volume_shader
	Fragment = volume_shader
}
