Scripts

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.

The syntax is the following:

ULON
Script script_name =
#{
    // UnigineScript code
#}

As a node’s value you must specify a UnigineScript-based code enclosed in "#{" and "#}".

Usage Examples#

The script node is usually used as a script value for the Expression node.

ULON
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:

ULON
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.

Source code (ULON)
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
#}
