This page is a part of the Lua and UI Reference.
Firaxis Hungarian notation
What is it?
Firaxis used a naming convention categorized as Hungarian Notation. The prefixes provide informations regarding the type.
- s, sz and str mean a string.
- Example: sName expects something like "Genghis Khan".
- b means boolean.
- Example: bHide expects true or false.
- f means floating-point, a number.
- Example: fScale expects a scale factor, may be 0.5, 1.0, 2.0, etc.
- i means integer, a number. Sometimes it may be one of the identifiers listed on the main page.
- Example: iPlayer expects a PlayerID while iWidth expects a width in pixels (50, 200, etc).
- e means an identifier (integer) taken from a Lua enumeration.
- Example: eBuilding expects a BuildingType. You could assign it with 10 or
GameInfoTypes.BUILDING_SEAPORT, both are equivalent.
- Example: eBuilding expects a BuildingType. You could assign it with 10 or
- p means an API object (p means pointer but pointer is a C term with no relevance in Lua).
- Example: pPlayer expects a Player object.
Should you use the same notation?
- Pro: it's widely used in the community and your code will harmonize with the one from Firaxis.
- Pro: you always now the type of a variable by looking at its name, which is useful since ModBuddy does not inform us about the type.
- Con: it adds some clutter and it's not really necessary because most of the time a consistent naming is enough to know the type of a variable: for example playerID for a PlayerID and player for a Player.
