### Interactive Points

These SimVars are used in relation to the values of the [Interactive Points](../../../../content-configuration/cfg-files/flight_model.cfg/#interactive-points) that have been defined for the aircraft. Each of these SimVars requires a *name* (or an *index* value) to be supplied, and this is the name (or index) of the corresponding `interactive_point.N` defined in the appropriate CFG file. This name can be given using the following format:

``` xml
[SimVar]:'[COMPONENT_NAME]'_n
```

For example:

``` xml
(A:INTERACTIVE POINT BANK:'Door_1'_n, Volts)
```

It should be noted that there are two versions of these SimVars, and for all aircraft developed specifically for MSFS 2024 you should be using the EX1 versions. The legacy versions do not work well with the `'[COMPONENT_NAME]'_n` format, and will fall back to index 0 when given an invalid index/name parameter. The EX1 versions will instead either return default values or simply do nothing.
