# Rules: Battle Audio

These are rules that are used to customize certain music tracks for this battle.

<details>

<summary><mark style="background-color:green;"><strong>"battleBGM"</strong></mark></summary>

You can use this rule to customize the BGM that will play during this battle.\
This is entered as `setBattleRule("battleBGM", String)`, where "String" is the file name of the track you want to play.

If you set this to an empty string, like `""`, then this will make it so the battle will have no battle music at all.

</details>

<details>

<summary><mark style="background-color:green;"><strong>"victoryBGM"</strong></mark></summary>

You can use this rule to customize the victory music that will play upon winning this battle.\
This is entered as `setBattleRule("victoryBGM", String)`, where "String" is the file name of the track you want to play.

If you set this to an empty string, like `""`, then this will make it so that this battle won't play any victory music at all. Instead, the battle music will just continue to play until it fades out.

</details>

<details>

<summary><mark style="background-color:green;"><strong>"lowHealthBGM"</strong></mark></summary>

You can use this rule to customize the low health music that will play upon the HP of the player's Pokemon falling to critically low levels.\
This is entered as `setBattleRule("lowHealthBGM", String)`, where "String" is the file name of the track you want to play.

If you set this to an empty string, like `""`, then this will make it so that this battle won't play any low HP music at all. Instead, the battle music will just continue to play as it normally would.

</details>

<details>

<summary><mark style="background-color:green;"><strong>"captureME"</strong></mark></summary>

You can use this rule to customize the jingle that plays upon successfully capturing a wild Pokemon. This is entered as `setBattleRule("captureME", String)`, where "String" is the file name of the track you want to play.

If you set this to an empty string, like `""`, then this will make it so that this battle won't play a capture jingle at all.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://lucidious89-tutorials.gitbook.io/deluxe-battle-kit-tutorial/deluxe-battle-kit-for-v21.1/deluxe-battle-rules/rules-battle-audio.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
