Configuration#

goboscript uses a goboscript.toml configuration file to store project-specific configuration.

Standard Library Version#

If not provided, the latest version is picked (Updates fetched daily)

std = "2.1.0" # default is unset

Sprites layer order#

Specify the order in which sprites are layered, by default the order is alphabetical by name.

layers = ["sprite_name_1", "sprite_name_2"]

Bitmap Resolution#

Controls the resolution handling for bitmap images (PNG, BMP) in your project.

bitmap_resolution = 2 # default is 1

How Bitmap Resolution Works#

Scratch internally uses high-resolution bitmaps where each screen pixel corresponds to 4 image pixels (2x scale factor). This setting determines how goboscript handles this scaling:

  • bitmap_resolution = 1 (default): Your images are stored as-is, and Scratch automatically scales them up by 2x when the project loads. Use normal-sized images (e.g., 480x360 for full stage backdrops).

  • bitmap_resolution = 2: Your images are treated as high-resolution and displayed at half their pixel size. You must provide double-sized images (e.g., 960x720 for full stage backdrops) to achieve the same visual size.

Note

This setting only affects bitmap formats (PNG, BMP). Vector formats (SVG) are unaffected.

Turbowarp options#

goboscript can generate a turbowarp configuration comment inside the Stage. https://docs.turbowarp.org/advanced-settings
