Newlife uses a number of data types, some standard, some specialized.

Standard

Type	Description	Notes
Object	This is an object type as defined here (e.g ClothingItem).	Sometimes abbreviated as "obj". Further methods can be called on this e.g. `$w.getLegwear().getBasicDesc()`
String	A text string.	Sometimes abbreviated as "str". These include both Strings intended for direct insertion into output and enumerated values.
Enum	An enumerated string.	These are technically strings but valid values are from a set range. They are usually all uppercase. They are defined in the enum reference documentation that are intended to be tested in conditional statements. If a method takes an enum value as a parameter then it will error if provided a String that isn't a valid type for that enum.
Boolean	A true/false value.	Sometimes abbreviated as "bool".
Void	Null	Only in return types. This means the method returns nothing. Typically the case for methods that change the game's state.
Integer	An integer (whole-number) numeric value.	Often abbreviated as "int". Newlife custom scenes do not use any floating-point numbers: only integers.

Velocity also uses the above types and also uses lists (single dimension arrays) and maps (hashed arays).
