This will be more of a FAQ on some important notes before you embark on your next big bot project!
|
|
|
|
## Default Abilities
|
|
|
|
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
|
|
There is a global flag in AbilityBot that restricts the kind of "updates" it can process. The default implementation is passthrough - it allows all updates to be processed.
|
|
As an example, if you want to restrict the updates to photos only, then you may do:
|
|
|
|
```java
|
|
@Override
|
|
public boolean checkGlobalFlags(Update update) {
|
|
return Flag.PHOTO;
|
|
}
|
|
``` |
