Learning Libgdx Game Development

Exploring Scene2D (UI), TableLayout, and skins

Libgdx comes with a great feature set to easily create scene graphs. A scene graph is a hierarchically organized structure of objects similar to files and folders on a hard disk. In Libgdx, such objects are called actors. Actors can be nested to create logical groups. Grouping actors is a very useful feature, since modifications applied to a parent actor will also affect its child actors. Furthermore, each actor has its own local coordinate system, which makes it very easy to define relative offsets inside a group of actors including position, angle of rotation, and scale.

Scene2D supports hit detection of rotated and scaled actors. Libgdx's flexible event system allows handling and routing inputs ...
