Arx scripting language

This article describes the scripting language used in Arx Fatalis and Arx Libertatis.

Variables

Main article: Script:Variables.

Arx scripts know three basic data types: int, Template:Real and Template:Text. Variables can be either global (shared between all entities) or entity-specific. There are also special system variables than can only be read. The variable type is defined by the first character of the variable name.

Char	Byte	Scope	Type
#	0x23	global	int
&	0x26	global	Template:Real
$	0x24	global	Template:Text
§	0xA7	entity	int
@	0x40	entity	Template:Real
£	0xA3	entity	Template:Text
^	0x5E	system	(mixed)

While variables in Arx scripts are typed, there are no type restrictions for where variables are used: the types are converted automatically.
