Texture Atlas

Texture Atlas

A Texture Atlas asset is a texture asset with additional data which describes 'Frames' inside the texture. Frames are regions defined in the texture as a rectangle with a 'pivot' point which sets the positional and rotational center of the frame.

Texture Atlases are created by right-clicking on a regular Texture Asset and selecting Create Atlas. Or by changing the default asset settings to enable Create Atlases

The Texture Atlas is used in combination with the Sprite Asset to render 2D graphics.



The Frames of a texture atlas are keyed by a unique value, usually a integer string. The format of a frame is:

rect: [0, 0, 0, 0], // u,v,width,height - width and height in pixels
pivot: [0, 0], // x,y - as a proportion 0-1
border: [0, 0, 0, 0] // left, bottom, right - top in pixels

Texture Properties

In addition to frame data the Texture Atlas contains the properties as a texture asset.
