Backgrounds are important. They show the scenary of the scene. Duh. Without them, every scene in your game will look like that load program from The Matrix, and that gets old quick.

Since PCG is just regular HTML, the best way to implement a background is to add a standard img tag to the top of each Scenes file, above all your game objects.

<img src="/demo/images/cave.jpg" width="1200" height="800" alt="cave">
<game-object x="700" y="650">


The size of the image is effectively the size of your scene canvas. If you place any Game Object (or any of it’s derivitives) outside the bounds of the width and height of your image, they will appear to be floating in space outside the “world”. That is, unless you’ve designed something clever I haven’t thought of.
