I've been continuing work on getting the Status Bar (at the bottom of the screen) to "seamlessly" transition between levels of my NES game.

It now works properly when transitioning in all directions.

πŸ§΅πŸ‘‡


It's complicated because the status bar lives in the BG layer, so you would see it moving up/down the screen as you scroll up and down.

The Fix?

The NES renders the screen top to bottom, so I detect when it is drawing 1 pixel above the status bar. At that precise moment, in the middle of drawing the screen, I tell the renderer to skip down to 1 pixel BELOW the status bar.

This effectively erases the existence of the status bar in the middle over screen by redirecting the renderer to a different part of video memory for that section of the screen.

A bit like folding a piece of paper over itself to hide some of the contents.

You may notice that during the video, the Status Bar sometimes vanishes.

This looks pretty bad, but is actually a simple thing to fix!

It is happening because my level streaming logic is not yet accounting for the status bar area, and loading level data in over top of it. I just need to stream in less data.

The only reason it isn't fixed yet, is because I hope to get a little performance boost out of it, so I want to take some time to measure just how much of a boost I get. 😁

With a LOT of help from the #nesdev Discord, I was able to clean up the seam above the status bar.

Also there's some new (temp) art, and I even perform the forbidden mid-frame palette update for extra colors!
