# Input hints

How interaction work from inside

All interactions extends from base class `Interactable` and should override next methods:

* `UsePrimaryActionHint()` 
* `GetPrimaryHintText()`
* `UseSecondaryActionHint()`
* `GetSecondaryHintText()`

This methods determine if action script will show any hints or not. For example:

```csharp
UsePrimaryActionHint() => true;
GetPrimaryHintText() => "Pick object";
UseSecondaryActionHint() => true;
GetSecondaryHintText() => "Examine";
```

UseSecondaryActionHint() => false;
GetSecondaryHintText() => default;
```

> Also, remember: If you want that action hints to be changed, you need to call method [`UpdateHints()`](/easy-interaction-system/creating-new-interactions/interaction-anatomy/input-hints/updatehints.md) from interaction script.
