## PsMenuActionEvent

`com.realisticnode.rnpsmenu.api.PsMenuActionEvent` is called just before rnPsMenu changes a region for a player, after every check has passed. Cancel it to stop the change.

```java
@EventHandler
public void onAction(PsMenuActionEvent e) {
    if (e.getAction().equals("unclaim") && isInWar(e.getPlayer())) {
        e.setCancelled(true);
    }
}
```
