Scrollin' scrolling' scrollin'...

 A couple of days ago I implemented the landscape scrolling and, much to my amazement, it actually worked first time - at least until the end of the first stage.

In the last few days I've been working on getting the so-called ground-based objects rendering. There was a bit of infrastructure to implement and also a minor re-architecture on some of the structures in RAM (simplfying them) but after fixing a bug this morning I've got the rockets rendering.

Too bad I can't upload a video of the scrolling landscape

Getting the rest of the ground-based objects rendering should now be straightforward, as they're all handled using a common object structure.

In fact looking at the disassembly it looks like most of the variables have been defined in the C code, so hopefully that'll be the last tweak of the structures.

The next few days will likely involve just working through the routines to create the rest of the ground-based objects and then 'animating' them which I am assuming is how the rockets are launched. Since the code simply operates on the existing structures, it should be a matter of cranking the handle.
