Atlas Editor

Atlases in Buildbox store all images in your game. To access the Atlas Editor, on the menu bar, select View and click Atlases.

This is an advanced Editor that allows you to edit atlases and individual sprite files.

Editing Atlas Attributes

To edit an atlas, select it in the panel on the left and update it as needed in the Options panel on the right.

The more Atlases are present in a game, the larger your exported game will be. In general, the smaller the game size, the better it is for memory usage and download size of the app.
Option Description
Name Enter a custom name for the atlas, if needed.
Width Enter the number of pixels as a base-2 number, such as 256,52, 1024, 2048, and so on, to specify the width of the atlas.
Height Enter the number of pixels as a base-2 number, such as 256,52, 1024, 2048, and so on, to specify the height of the atlas.
Padding Enter a non-zero number of pixels to specify the space between individual sprites.
Optimize Click to remove unused images.
Rebuild Click to reorganize the images in a way that uses the Atlas space most efficiently.

Editing Sprite File Attributes

To edit an individual sprite from an Atlas, expand the Atlas and select the sprite name in the left pane. Otherwise, click the image in the Editor. The sprite attributes appear in the Options panel.

To edit image properties, such as brightness, contrast, hue, and saturation, you need to open the sprite image in the Sprite Editor and update its attributes in the Options panel.

Option Description
Name Enter a custom name for the file, including the file extension.
Format Enter the file format. Currently only PNG is supported for images.
Offset The offset and position for the image on the screen.
