脚本

This type of node is used to write a UnigineScript logic in an ULON-based material file. The Script node specifies a single script that can be used in different Expression nodes.这种类型的节点用于在基于 ULON 的材料文件中写入 UnigineScript 逻辑。 Script 节点指定可以在不同的 Expression 节点中使用的单个脚本。

The syntax is the following:语法如下：

Script script_name =
#{
    // UnigineScript code
#}

As a node’s value you must specify a UnigineScript-based code enclosed in "#{" and "#}".作为节点的值，您必须指定包含在 "#{" 和 "#}" 中的基于 UnigineScript 的代码。

The script node is usually used as a script value for the Expression node.脚本节点通常用作 Expression 节点的脚本值。

Script named_script =
#{
    // UnigineScript code
#}

Expression expression_name = named_script

You can also specify a path to an external script file (in usc or h format) or the name of a different Script node inside this material:您还可以指定外部脚本文件的路径（以 usc 或 h 格式）或此材料中不同 Script 节点的名称：

Script external_script = "some/path/to/your/script.usc";	// script.usc consists of some UnigineScript code

Script linked_script = external_script 

Expression RENDER_CALLBACK_* = linked_script

To include the code of a different script use the following marker: #script script_name.要包含不同脚本的代码，请使用以下标记：#script script_name。

Script a = 
#{
        // UnigineScript code A
}#

Script b = 
#{
        // UnigineScript code B
        #script a
}#

// the result script b will look like this: 
Script b = 
#{
        // UnigineScript code B
        // UnigineScript code A
#}
