Background Effect - Damnae/storybrew GitHub Wiki
Minimal configuration
The Background effect does not need any configuration, as long as your map has a background.
Configurable fields
SpritePath
The path to an image to use as a background. Will use the map's background if this is left empty.
StartTime / EndTime
The period of time during which the background will be visible. If they are equal, the EndTime will be set to the time of the last hitobject, or at the end of the song if there are no hitobjects.
Opacity
Adjust the background's transparency, where 0 is completely hidden and 1 is fully visible.
