Scratch File Format (1.4)/Sprite File

This article or section documents something not included in the current version of Scratch (3.0). It is only useful from a historical perspective.

This is a technical description of the file format. For sprites in general, see Sprite.

A sprite file is used to save a single sprite that can be imported into other Scratch projects. They have the extension .sprite.

Structure

Perhaps confusingly, sprite files do not just contain a sprite object.

They actually contain a stage object encoded as an Object Table (the same as the project file contents). This is because global variables/lists need to be saved as well.

Unlike a project file, there is no preceding ScratchV02 header or info table; just the single object table for the stage.
