An Example of a YAML Scene File

An example of a simple but complete sceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info

is given below. The scene contains just a cameraA component which creates an image of a particular viewpoint in your scene. The output is either drawn to the screen or captured as a texture. More info

and a cube object. Note that the file must start with the two lines
