First off, you can't rotate a background with draw_background_tiled. However, you can draw anything on a BIG surface, and a surface can be rotated and doubled up.

So, the infinite floor uses a surface, and now it's not chugging so hard. Look at the FPS.

I made an up-to-date trailer for Terry's Treasure Trouble!

You know, in case it wasn't clear what kind of game this is.

Three reasons to be going after the treasure:

Trying to do that Infinite Floor thing (technically, it's a trick of the camera), and I think it chugs.

Makes sense, since it's drawing on one surface over and over for each scanline, then putting that on another surface, which puts that on-screen.

Hmm...

I'm getting closer to my goal here.

All these rock piles are gonna loop indefinitely for now. My goal is to make the road widen, tighten, and move side-to-side with the walls.

...and replace the grassy floor with something more fruitcake-like.

A step-by-step process for bigger sprites.

GM Studio 1 works like Windows XP's Paint, but with nicer features. As such, even a lefty like me can learn to draw right-handed with a Line tool.

...well... This is awkward.

Yes, I CAN make an animated background within a matte, with a shifting color palette. However, I realize this doesn't look like lava, no matter which way you shake it.

...the effect's cool, though.

I might have gone too far in a few places, and not enough in others.

The only thing harder than animating a set of wheels is making it handle like a set of wheels.

...and making an infinite floor without resorting to the official 3D engine.

Still working on it.

There's definitely treasure around here, but it'll still take a while 'til we reach it.
