This will be more of a FAQ on some important notes before you embark on your next big bot project!
|
||
|
|
|
||
|
|
## Default Abilties
|
||
|
|
|
||
|
|
It is possible to declare "DEFAULT" abilities that process non-command messages. This is quite close to a reply. If a user says "Hey there" and the default ability is implemented, it will process this input.
|
||
|
|
```java
|
||
|
|
/**
|
||
|
|
* This ability has an extra "flag". It needs a photo to activate! This feature is activated by default if there is no /command given.
|
||
|
|
*/
|
||
|
|
public Ability sayNiceToPhoto() {
|
||
|
|
return Ability.builder()
|
||
|
|
.name(DEFAULT) // DEFAULT ability is executed if user did not specify a command -> Bot needs to have access to messages (check FatherBot)
|
||
|
|
.flag(PHOTO)
|
||
|
|
.privacy(PUBLIC)
|
||
|
|
.locality(ALL)
|
||
|
|
.input(0)
|
||
|
|
.action(ctx -> silent.send("Daaaaang, what a nice photo!", ctx.chatId()))
|
||
|
|
.build();
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
This ability will send a *"Daaaaang, what a nice photo!"* whenever the bot receives a photo. This is one use case where replies and abilities are interchangeable.
|
||
|
|
|
||
|
|
## The Global Flag
|
||
|
|
However, there is one important note here. This ability without any additional code will not be able to process photos. There is a global flag in AbilityBot that restricts the kind of "updates" it can process.
|
||
|
|
To freely process any update given to your bot, make sure to:
|
||
|
|
|
||
|
|
```java
|
||
|
|
/**
|
||
|
|
* By default, any update that does not have a message will not pass through abilities.
|
||
|
|
* To customize that, you can just override this global flag and make it return true at every update.
|
||
|
|
* This way, the ability flags will be the only ones responsible for checking the update's validity.
|
||
|
|
*/
|
||
|
|
@Override
|
||
|
|
public boolean checkGlobalFlags(Update update) {
|
||
|
|
return true;
|
||
|
|
}
|
||
|
|
```
