A variable type which can have one of two values: <code>true</code> or <code>false</code>. Wikipedia has a comprehensive article on [[wikipedia:Boolean|Booleans]].
 
== Advanced ==
Booleans used in prototypes can also be be defined by other variable types which are then coerced to boolean values by the game. This type coercion differs from the [https://www.lua.org/manual/5.2/manual.html#2.1 standard Lua truthy/falsy] coercion.
 
It is recommended to only use <code>true</code> and <code>false</code>, not the options listed below.
