Detailed Description

Representation of an in-game level.

A Level is a discrete section of the game, each with a well defined start and end. Most Levels in VoltAir start at the Robot's spawn point and end when the Robot successfully enters an activated Portal.

Levels are comprised of a collection of Actors (for example, the Robot). The data describing the initial state of these Actors is loaded from data (QML) and instantiated into a tree structure. Nodes are QQuickItems or QObjects, and form part of the QML tree. The Level object itself becomes the parent of all of these objects.

Aside from containing Actors, the Level is responsible for maintaining some of the state that is global to the Level, such as the intensity of gravity. The Level is also the owner of the physics world (b2World).
