This category only has one file: a video that plays in the background of the main menu. This isn't used at all in the default game, it's a feature specific to Resource Packs.
This category uses JSON files. JSON files are used to set additional information which can't be specified in the file itself. To use a JSON file, make a new file of file type .json with the same name as the file you are setting information for. For example, if you're setting custom information for the file rifle.png, you would make a new file named rifle.json. Inside the JSON file, you can set variables which will affect how the file is affected in-game. Each file page has an example of the default JSON it uses, so you can see which variables you can modify. Additionally, the table below shows all modifiable JSON variables for this category.
| Name | Description |
|---|---|
| width | The width of the video, in pixels. |
| height | The height of the video, in pixels. |
| mute | true (mute audio) or false (play audio if the video has it). |
