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)
