Vanilla Quake-C files make ample use of binary flags for entity properties as disparate as whether the entity is touching the ground to which weapons a player possesses.
Binary flags can be thought of as a bunch of switches that are either on or off pushed up next to each other. The weapons are a great example of this:
| item flag-constant | integer value | 2 | binary value |
|---|---|---|---|
| IT_SHOTGUN | 1 | 2^0 | 0000 0001
|
| IT_SUPER_SHOTGUN | 2 | 2^1 | 0000 0010
|
| IT_NAILGUN | 4 | 2^2 | 0000 0100
|
| IT_SUPER_NAILGUN | 8 | 2^3 | 0000 1000
|
| IT_GRENADE_LAUNCHER | 16 | 2^4 | 0001 0000
|
| IT_ROCKET_LAUNCHER | 32 | 2^5 | 0010 0000
|
| IT_LIGHTNING | 64 | 2^6 | 0100 0000
