Background

Hi Clickers,

does anyone of you know the game "Donkey Kong Country 2"?
In the 3rd Level (inside the ship) the game has a neat background which I would like to create in MMF 2. Does anybody know how to do something like that?

For all of you who don't know what I mean. The background in that level is not just vertical perspective. It is horizontal too. At the beginning of that level the player is automatically falling down. By the way the background scrolls it looks like the player is falling through the ceiling.

The same thing in the Game "Sonic the Hedgehog 3" for Genesis in 2nd level when Sonic falls into the water.

There`s an example of what I'm talking about:

I have seen this done - I think it was achieved using the Perspective object for the floor and ceiling, and stretching external images as appropriate.

You've got the Hydrocity music stuck in my head now.

*g* sorry for that.

I already use the perspective object for the floor which works fine. But I don_'t know how to strech or shrink an image depending on the scrolling.

Yeah I don't think the perspective object alone would work for that. You could make the floor an active object and scale it vertically depending on the position of it in relation to the screen, and also have a perspective object on top of it to give it the illusion of depth.

Using something like Mode 7 would work, that's really the only other way I can think of without using hundreds of layers or faking the 3D effect with an animation of the floor skewing which progresses in frames as fast the screen scrolls.

I saw this effect in The Chaos Gate, which Ben Berntson has now abandoned for the moment, maybe ask him, see what he says?

I just realized that the perspective object has no Set Width/Height actions :S
I will add them asap.

@AsparagusTrev: I've been thinking about using Mode 7 but I ain't got no clue what kinda effects I can create with it and how.

@ChrisStreet: Where can I find that game? I googled it but there's no page where I can download it.

@Andos: Your extension is great! Just have to tell you that.
I don't know nothing about "real" programming. That's why I thank everyone who makes a great extension!

Does anyone know how you can create an effect like that using mode 7?

I got thinking and maybe we can solve that problem by calculating the distance bewteen 2 actives and using this distance to resize a 3rd active. Do you think that would work?

I tried it but somehow I can't get it to work. I'm just frustrated anymore because I'm just not smart enough to think the way programmers think! Test-File

What I thought of is resizing a floor object. From the top, as it's reaching the middle of the screen it would shrink downwards, then as it's passed the middle it would start to grow again.

Take a look at my Test-File again (see above).

Looks pretty good so far (at least to me it does). The only problem left, how do i get a left/right-perspective? the perspective-object would be the best choice, but it can't be resized...

Cant you just make a big animated active object in a background layer? That wouldn't be too hard.

Sure you can, but why would you wanna do that? The way I got it solved is better I think! Besides that, one big animatied active in the background would slow it down.

Just check it out!
