Background Scroll effect, how?

[N64Mario]

I'm wondering if this background scrolling technique is possible, and how?

Specifically, look at how the floor and/or ceiling moves. The tiles aren't exactly equal every time when you move left or right. Is this possible if each of the floor sprites displayed is 1 tile high, and for each 1 tile, just move them at different speeds? Or is there another way to achieve this?

Also, this won't be automatic scrolling. It'll be scrolling based on the positions of players 1 and 2.


And I can't seem to delete stuff that I just uploaded to my attachments.

I don't think this is possible with a 2D effect. You could render out a 3D sequence as 2D and use that as a sprite, but in terms of getting that perspective, I don't see it being possible. It's not as simple as just offsetting speeds of tiles. The entire perspective of the tiles is being skewed.

The example image you provided is using two 3D planes with textures mapped to them, and then a 3D camera perspective.

Check out the MMF2 Parallaxer extension: http://www.andersriggelsen.dk/mmf2_extensions.php . I've never used it, and don't know if it's CF2.5 compatible, but it sounds like what you're looking for.

The parallaxer object seems to work on CTF 2.5. Except that in the example provided, it keeps crashing on frame 1. On the other frames, it works fine.

Hi N64Mario and all clickers! See this theme on site: http://www.extentofthejam.com/pseudo/. This is possible without special extensions!

that's a great link crayzorechos ! always curious about some of those retro effects.

Hi DaveC and all clickers! Yeah this is great cool link, but how know, maybe anybody create example for pseudo 3D racing game! This is will be cool and nice!

This is nice and all. It gives some great details, info about the effect. Though I was hoping for an explanation in CT Fusion that I could understand. :-/

Hi N64Mario! Yes it is be cool, but maybe some not understanding for you! But if you have brain and lucky, you can make this. Sorry for aggression style of my post, but if you have programing algorithmic logic you can do this!

Well...... I can only think of one way to do this, and it's the method I said before. To try and crop each height of the floor sprite as 1 pixel high, and place them together in MMF2/CTF, but move them in different velocities. But i don't know how that would work in terms of # of objects being used, RAM usage, etc.
