Settings

gunslinger.lite [bool] (defaults to false)

gunslinger.disable_builtin [bool] (defaults to false)
- Enables/Disables builtin guns - only the API will be provided.
- Useful if mods/games provide custom guns.

Architecture

Gunslinger makes use of gun types in order to ease registration of similar guns. A type is made up of a name and a table of default values to be applied to all guns registered with that type. Types are optional, and can also be omitted altogether. Guns are allowed to override their type defaults, for maximum customisability. Raycast is used to find target in line-of-sight, and all objects including non-player entities take damage.

Final damage is calculated like so:

Initial/rated damage = def.base_dmg
If headshot, damage is increased by 50%
If shooter was looking through scope, damage is increased by 20%

Lite mode

Enabling lite mode will disable the realistic/fancy features which are potentially lag-inducing. Recommended for large servers.

Note: As of now, enabling lite mode will only disable automatic guns, but there are plans to allow lite mode to disable much more.

Automatic guns

gunslinger supports automatic guns out of the box, while not causing excessive lag. This is achieved by adding players who left-click while wielding automatic guns to a special list, and the entry remains in the list only as long as their left mouse button is held down. A globalstep iterates through the table and fires one shot for all players in the list (while also respecting the fire-rate of the wielded guns).

The use of a dedicated list improves performance greatly, as the globalstep would have to otherwise iterate through all connected players, check if their mouse button is down, and only then, fire a shot. Nevertheless, disabling automatic guns (by enabling lite mode) is recommended on large public servers as it would still cause quite a bit of lag, in spite of this optimisation.

gunslinger provides a setting "gunslinger.enable_automatic". Disabling this setting will throw an error when an automatic gun is registered.
