Sprite Editor



The viewport in the Sprite Editor shows the currently selected Texture Atlas. Frames are shown as grey boxes on the texture atlas. The currently selected asset is shown with two sets of handles. green and blue. Green handles modify the frame's width and height, blue handles modify the frame's border property.

Editing Texture Atlases

Within the viewport use the mouse to drag the outline of a Frame, then use the green and blue handles to modify the frames extents and borders.


Frames are a defined region on a Texture Atlas. A frame has a name, a position and size and a border. The border is used to define the edges of the 9-slicing region. See the 9-slicing documentation for more information.


The inspector panel shows the properties of the currently selected item. The inspector changes depending on whether the selected item is a Texture Atlas, Frame or Sprite Asset.

Then select the method of specifying the grid cells

  • Grid By Frame Count - Specify the number of grid cells horizontally and vertically to divide the texture into
  • Grid By Frame Size - Specify the size in pixels that each grid cell should be

Then set the values for Offset and Spacing. Offset is the number of pixels to move in from the top left of the texture before starting the grid. Spacing is the number of pixels between each grid cell.
