A boolean value is a toggle used in programming that is inherently exclusively either "on" or "off". When enabled it is denoted with true or 1, and with false or 0 when disabled, depending on the syntax of the language being used.
Its use varies in different areas of the engine:
- C++ code generally uses
true / false, which occupies 1 byte. - The unmodified
Half-Life SDK uses BOOLto represent boolean values, it is a typedef forint; therefore it uses 4 bytes instead of 1. - Materials use
1 / 0 - Weapon Scripts use
1 / 0 - .VMF files use
1 / 0 - .DMX files Todo: Verify how, and which form
- .VCD files use
1 / 0
Certain file types used in Source also do not typically use booleans:
