Translate: - English - Türkçe - 中文 - українська мова 

An image of the Stage with a sprite on it (the Scratch Cat). A thumbnail of the stage is on the left.

The Stage is the term for the background of the project, but can have scripts, backdrops (costumes), and sounds, similar to a sprite. It has some restrictions of sprite functionality, such as motion and size blocks.

No sprites can move behind the Stage — the Stage is always at the back layer.

Differences from Other Sprites

There are many differences between the Stage and other sprites. These include the following:

• Is stationary

— thus,

• • Cannot use Motion Blocks
  • Cannot use any Pen functions, other than Clear
  • Has no size blocks
  • Has no "touching" blocks in the Sensing category
  • Has no "distance to" block in the Sensing category
• Cannot talk

— thus

• • Has no "Say" or "Think" blocks in the Looks category
  • When asking, places the question above the text box rather than in a speech bubble.

• Has backdrops instead of costumes
• Cannot be renamed
• Has no "show" or "hide" blocks in the Looks category
• Cannot change layers

— it is always at the very back layer.

• Must have a 480x360 dimension
• Space in backgrounds left transparent becomes white automatically

Scripting

The Stage field has a scripts tab that can be used in the same way as in a sprite, with the following exceptions:

• The motion, say, think,

Show, Hide, costume, size, layer, Costume #, pen (except Clear), When I Start as a Clone, Delete This Clone, touching, and Distance to () blocks cannot be used.

• The

Switch Backdrop to () and Wait, Next Backdrop, and Backdrop # blocks are only for the Stage. This field is optional.

There is also a backdrops tab that can be used to add, delete, and edit backdrops. This field is required, and you cannot delete a backdrop when it's the only one. The dimensions are always 480x360. Transparent areas automatically become white in the project.

The optional sounds tab is identical to the sounds tab in sprites.

Stage Sizes

The stage can be 3 different sizes:

Regular

Normal mode; the Stage is 480x360 pixels

Small Stage Layout

The stage is half the size with a resolution of 240x180 pixels; this is useful for having more room in the scripts area.

Full-screen mode

Main article: Full Screen

fits the player to one's web browser's current resolution

History

Originally the Stage was included as another sprite in the sprite corral (now the sprite pane) and called the "Background".

The Stage was introduced in Scratch 0.2.
