# Overview
|
|
## Advanced ballistics simulation
|
|
The advanced ballistics module improves projectile physics by simulating internal and external ballistics. Factors used in the simulation include:
|
|
|
|
- Ambient air pressure, temperature and humidity
|
|
- Wind drift
|
|
- [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 on powder burn rate and barrel length
|
|
- Barrel length effect on muzzle velocity
|
|
|
|
## Advanced drag model
|
|
Realistic drag modeling based on the G Model and real-world ballistic coefficient data.
|
|
|
|
## Wind simulation
|
|
Wind speed varies with altitude. Terrain features, buildings and other objects disrupt the wind.
|
|
|
|
## Bullet trace effects
|
|
Supersonic bullets have a refraction effect due to air pressure waves.
|
|
|
|
## Protractor
|
|
Adds a protractor for quickly measuring inclination angle.
|
|
|
|
# Usage
|
|
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.

|
This module uses relatively complex scripting. Several options are provided in the ACE menu to reduce the performance impact of this module.
