## 1. Requirements

Object must inherit from `ThingX` or any of its sub-classes.

Object must have Extended Event Handler (XEH) enabled (this is not the case for the majority of vanilla objects in `ThingX` class), configuration entry on how to do that is shown below.


## 2. Config Values

```cpp
class CfgVehicles {
    class MyChair {
        ace_sitting_canSit = 1;  // Enable sitting
        ace_sitting_sitDirection = 180;  // Direction relative to object
        ace_sitting_sitPosition[] = {0, -0.1, -0.45};  // Position relative to object (may behave weird with certain objects)
        XEH_ENABLED;  // Enable XEH (only necessary if XEH is not yet enabled for this class or the one this inherits from)
    };
};
```
