## 1. Overview
The Advanced Ballistics module improves internal and external ballistics. 

## 2. Features
- Drag modeling based on real-world ballistic coefficients.
- Ambient air density (air pressure, temperature, humidity) affects drag.
- Wind affects drag and deflects the trajectory.
- Wind speed varies with altitude.
- Terrain features, buildings and other objects disrupt the wind.
- [Magnus effect](https://en.wikipedia.org/wiki/Magnus_effect) (spin drift)
- [Coriolis effect](https://en.wikipedia.org/wiki/Coriolis_effect) and [Eötvös effect](https://en.wikipedia.org/wiki/Eotvos_effect) (Earth rotation)
- Loss of stability during transonic flight.
- Variable muzzle velocity based on powder burn rate and barrel length.
- Bullet trace effect for supersonic bullets (light refraction due to air pressure waves).
- A protractor for quickly measuring the inclination angle.

## 3. Usage

### 3.1 Protractor
Press <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>K</kbd> while using a compatible weapon to toggle the protractor. The red line indicates the current inclination angle in degrees. The protractor will disappear if you lower or holster your weapon.

## 4. Dependencies
`ace_ballistics`, `ace_weather`, `ace_modules`
Create missing documentation placeholders Creates placeholder documentation for modules which did not previously have any. If a module had the same name and apparent purpose as a module from AGM, AGM's documentation was imported into the placeholder. These documentation are useful to users for explaining what ACE3 changes. They are also useful to community admins who want to create a custom distribution of ACE3 and need to know which modules to disable. The documentation needs to be significantly fleshed out before it's ready for public consumption, but this should be a helpful start. 2015-05-13 00:28:18 +00:00			`---`
