Sprites

Sprites are the objects in your project: characters, buttons, backgrounds of movement, anything with its own scripts, costumes, and sounds. The sprite pane sits below the stage and lists every sprite, shows the selected sprite's properties, and lets you add new ones.

A new Bilup project starts with one sprite named Misty.

The sprite list​

Each sprite appears as a tile showing its thumbnail and name. Click a tile to select that sprite; the Code, Costumes, and Sounds tabs then edit that sprite. The selected sprite is highlighted.

Right-clicking a sprite tile opens a menu with:

  • duplicate: make a full copy, including scripts, costumes, and sounds.
  • export: save the sprite to your computer as a .sprite3 file, which you can import into another project.
  • rename
  • delete

You can drag tiles to reorder them.

Sprite properties​

When a sprite is selected, its properties appear above the list:

  • Sprite name: rename the sprite.
  • x and y: its position on the stage.
  • Show / hide: whether the sprite is visible (the eye buttons).
  • Size: scale as a percentage, where 100 is the costume's natural size.
  • Direction: the way the sprite points, set with the direction dial.

Editing these here is the same as the sprite doing it with motion and looks blocks; it is just the starting value.

Rotation style​

The direction dial also sets the rotation style, which controls how the sprite turns:

  • All around: the costume rotates freely to face its direction.
  • Left-right: the costume only flips horizontally, so it never appears upside down.
  • Don't rotate: the costume never turns, whatever the direction.

Adding sprites​

The round add-sprite button (bottom-right of the pane) offers four ways to add a sprite:

  • Choose a Sprite: pick from the built-in sprite library.
  • Paint: create a blank sprite and open the paint editor.
  • Surprise: add a random sprite from the library.
  • Upload Sprite: load an image or sprite file from your computer. Accepted types include .svg, .png, .bmp, .jpg, .jpeg, .jfif, .webp, .gif, and Scratch sprite files (.sprite2, .sprite3). You can select several files at once.

The stage and backdrops​

To the right of the sprite list is the stage tile. Selecting it lets you edit the stage's scripts, its backdrops (the Costumes tab becomes Backdrops), and its sounds. The stage cannot move, so it has no position, size, or direction, but it can have many backdrops and switch between them.
