| Ah, that explains it. I didnt look too closely at Rocketry, so I must have missed that. Super cool idea to use that to make unlimited x scrolling possible. |

So I checked my old source code, I can linecrunch 5 lines too:
"lc_max = 5"
I use 0-4 for bitmap Y movement, and reserve +1 extra linecrunch for sideways motion to relieve vsp wraparound. |

| Thanks for the clarification info, yeah there are more twists than I could see at first. Haven't noticed the bitmap height difference, probably because of the repeating nature of the bitmap theme. Very cool! |

Hey Clarence, the AGSP is ofcourse based on yours in Rocketry. This version is multicolored (like you noticed), so 1000 more bytes to copy.
But also, new lines get added to the bottom of the bitmap (the picture is 40 rows high). So there is no 'skew' error, the picture is straight when it overflows at the bottom. This means you also have to copy one more row each frame, so an additional 320+40+40 = 400 bytes each frame.
In total there's 1000+6*400 = 3400 more bytes that get copied before a new bitmap takes over.
I managed one more line of linecrunch (0-5 lines of crunching). Rocketry could do 1 line less (0-4 lines of crunching).
This one extra frame is not enough to make it possible, the part uses a triple buffer method, reusing loads and storing twice.
Deekay did the picture in photoshop btw. The source loads in the 3 png files that Deekay made and converts it to UFLI-max. |

Nice mirrored distorter. Also nice to see the first ufli max pic. What editor did Deekay use?
I think I did a *very* similar LC free bitmap mover in 'Rocketry', would love to know what's difference here exactly. I see it's mc, and goes only upwards but 2 chars/frame. Is that it?
Mine had more freedom in sideways motion and could switch vertical direction in 1 chars/frame movement and was hires bitmap. |
