Help needed with Parallaxer

[Virginityrocks]

The author of the object advised me on his Youtube comment page to come here for advice instead of consistently pestering him about the nitty-gritty with his object.

Basically, what I want is to make the parallaxer image always center itself in relation to the camera. The current set-up, depending on where the parallaxer is placed, will usually give the wrong perspective. I uploaded an example image as a youtube video. For some reason I had thought this would be easier.

The parallaxer is a cube. In the left, we have what it is now, and to the right is how I would like it to behave.

Here is a link to a thrown-together example build.

The cube on the left is about right perceptually, but only because it was placed within the 640x480 perforated starter frame. The cube to the right is off. If the image were centered properly in relation to the camera, there would not even be cutoff, as you can see on the right cube.

I would suspect it has something to do with setting the offset to the camera's x position + ( screen size / 2 ), but that is only a guess.

Probably would be best to give us raw code to look at, an mfa. That way we can trouble shoot it for you.

I can't remember if this version is published yet, but my next version already has an option to keep a certain line stationary while the rest scrolls. It makes it easier to make that kind of cube effect you are trying to make. In fact I actually also made an example of doing what you are trying to do.

The in your case, you probably set the offset of all parallaxer objects to be: X("Player")
To adjust the parallaxer object's offset you need to take their x-position into account. It's a little bit difficult to describe. I will try to release the next version of Parallaxer object as quick as possible.

Thanks, Andos. You should post a link to this example!

[Anders]

Will do as soon as I release the new Parallaxer version.

Hey Andos. It wasn't too complicated at all. You really threw me off by making me overthink this!

All you have to do is subtract the player's X coordinate by the parallaxer's X coordinate. All solved.

Alright Andos. Next up the 320 Z-length isn't working as well as I had thought. It still moves much quicker than the rest of the frame and other objects.

Here. I posted the project file on filefront for you to see. If I set the z-length to 6000, it'll move at the same pace as the rest of the frame, but it destroys the 3d effect. Basically what I want is the Z-length to be 320, but for the front of the house to move at the proper pace, so that it looks like a flat 2d square with depth trailing behind it in parallel.

Those 2 actives in the windows should stay in those windows as the character moves left and right.
