## 1. Config Values

### 1.1 Whitelisting surfaces for digging

Single surfaces can be whitelisted by adding `ACE_canDig = 1` into `CfgSurfaces`.
```cpp
class CfgSurfaces {
    class myAwesomeSurface {
        ACE_canDig = 1;
    };
};
```

### 1.2 Enabling entrenching tool features on an item or backpack

```cpp
class CfgWeapons { // same config also works on backpacks (CfgVehicles)
    class yourBaseClass;
    class yourEntrenchingToolClass: yourBaseClass
        ace_trenches_entrenchingTool = 1;
    };
};
```
