## 1. Config Values
### 1.1 Launchers
```cpp
class CfgWeapons {
class MyLauncher {
ace_overpressure_angle = 60; // Cone in which the damage is applied (in degrees from the back end of the launcher)
ace_overpressure_range = 15; // Range in meters in which the damage is applied
ace_overpressure_damage = 0.7; // Damage multiplier
ace_overpressure_offset = 1; // Offset from the projectile, where the backblast originates
};
};
```
### 1.2 Cannons
```cpp
class CfgWeapons {
class MyBananaCannon {
ace_overpressure_angle = 90; // Cone in which the damage is applied (in degrees from the muzzle of the cannon)
ace_overpressure_range = 50; // Range in meters in which the damage is applied
ace_overpressure_damage = 0.85; // Damage multiplier
};
};
```
- You can note that the angle range and damage values are higher, that's because this is a cannon and the backblast area is bigger.
